                                  THE COMPANY
   
  The Company is the world's preeminent integrated media and marketing company
focused on computing and Internet-related technology, with principal platforms
in print publishing, trade shows and conferences, online content, market
research and education. The Company provides global technology companies with
marketing strategies for reaching key decision-makers.     
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the top
three computer magazines in the U.S. and are among the top 25 U.S. magazines,
each as measured by total revenue in 1996 (the latest year for which data is
available). The Company also produces the world's most important trade shows
serving vendors, resellers, buyers and users of computer technology, including
COMDEX/Fall, the largest trade show in the U.S. The Company's ZDNet.com Web
site ("ZDNet") is the leading computing content site and ranked the number one
Web site in 1997 in the category of news, information and entertainment, as
measured by visitors per month.
 
  The Company's 28 primary U.S. and international titles, including its joint
ventures, and over 50 licensed publications, total more than 80 publications
distributed worldwide, with a combined circulation of over eight million
primary readers. In 1997, Ziff-Davis was the largest technology publisher in
the U.S. in terms of total magazine revenue. In that same year, Ziff-Davis
accounted for 36.8% of all advertising and circulation dollars spent in
computer periodicals, with at least 50% more total magazine revenue than its
closest competitor. The preeminence of the Company's publications among readers
and advertisers is based on its comprehensive market and product coverage, the
quality of its editorial content and the influence of its readership.

with over two million estimated attendees. The Company's COMDEX/Fall event is
the number one ranked trade show for all industries in the U.S. as measured by
total revenue, total exhibit space and number of attendees.

market research, education and the publication of computer-related newsletters
and training manuals and materials. In addition, the Company has an option to
acquire an interest in ZDTV: Your Computer Channel ("ZDTV"), the first 24-hour

computers, technology and the Internet, which is expected to be launched in the
first half of 1998.

total revenue in 1997. The second largest component of the Company's revenue is
derived from trade shows and conferences, which accounted for 23.5% of total
revenue in 1997. Circulation revenue, comprised of subscription and newsstand
single copy sales, generated 13.1% of the Company's revenue in 1997 and other
revenue components, including online content, market research and revenue
derived from joint ventures and licenses, contributed 11.5% in 1997. The
Company had a net loss of $71.2 million for 1997 and expects the net loss for
the first quarter of 1998 to increase by 15-20% as compared with the first
quarter of 1997. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."     
 
BUSINESS AND OPERATING STRATEGY
 
  The Company's objective is to be the preferred marketing partner to
technology vendors and service providers seeking to reach primary decision-
makers involved in the specification and purchase of their products and
services. Major elements of the Company's strategy include:
 
  .Maintain Focus on the Computer and Internet Technology Markets
 
  .Develop the Most Comprehensive, Objective and Authoritative Content
 
  .Build Upon Brand Strength of Existing Media Properties
 
  .Continue to Leverage Multiple Media Marketing Platforms
 
  .Expand Leadership on the Internet
 
  .Launch New Products and Services
 
  .Expand Global Reach
 
  The Company expects to fund its business and operating strategy from
internally generated cash flow from operations, which are estimated to be
sufficient to fund investments and the repayment of indebtedness. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

RELATIONSHIP WITH SOFTBANK
   
  Upon the completion of the Reorganization described below, SOFTBANK Corp., a
Japanese Corporation publicly-traded on the Tokyo Stock Exchange First Section
(together with its affiliates, "Softbank"), will own approximately 74.2% of the
outstanding shares of Common Stock (71.4% if the U.S. Underwriters' over-
allotment is exercised in full). The Company and Softbank have entered into
certain agreements governing various interim and ongoing relationships between
Softbank and the Company. Softbank also has given the Company an undertaking
not to expand certain operations outside Japan in competition with the Company
without the prior approval of the Company's management directors after
consulting with the Company's independent directors. This undertaking would not
preclude investments by investment funds managed by Softbank. The Company has
undertaken not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s Board of Directors and has agreed to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest," "The Company--Relationship with Softbank" and "Certain
Transactions."     
 
  The following table presents Softbank's total historical investment in and
return on investment from the Company as well as the value of its investment at
the assumed initial offering price (calculated based on the midpoint of the

                               THE REORGANIZATION
   
  The Company is an indirect subsidiary of SOFTBANK Corp., which, as of
December 31, 1997, was 50.2% owned by Mr. Masayoshi Son, its President,
including 43.4% directly held by his 99% owned holding company, MAC Inc., a
Japanese corporation ("MAC"), and SOFTBANK Corp.'s largest shareholder. Prior
to the Offerings, the Company's businesses were conducted through various
indirect subsidiaries of SOFTBANK Corp. The Company's publishing business was
principally conducted through Ziff-Davis Inc. ("ZDI") and its trade show
business was principally conducted through ZD COMDEX and Forums Inc. ("ZDCF").
The MAC Assets were managed by ZDI and ZDCF, but were owned by MAC.
Concurrently with the Offerings, the Company will consummate a Reorganization
(as described under "The Reorganization") pursuant to which: (i) all of the
stock of ZDI and ZDCF will be contributed to the Company by Softbank in
exchange for 74.2% of the Company's Common Stock; (ii) the Company will
complete the purchase of the MAC Assets; (iii) the Company will issue and sell
the Common Stock and the Notes pursuant to the Offerings; (iv) the Company will
enter into a credit facility with a group of financial institutions (the
"Credit Facility") and borrow $1.25 billion thereunder; and (v) approximately
$928 million of the Company's obligations to Softbank will be converted to
equity and the Company will repay approximately $1.531 billion of obligations
to Softbank. The Company has obtained a commitment letter from The Bank of New
York, Morgan Stanley Senior Funding, DLJ Capital Funding and The Chase
Manhattan Bank to provide such Credit Facility. All of the transactions
comprising the Reorganization will be deemed to occur simultaneously. See "Risk
Factors--Risks Relating to the Reorganization," and "--Absence of History as a
Stand-Alone Company; Limited Relevance of Historical Financial Information,"
"The Reorganization" and "Unaudited Pro Forma Combined Financial Information."

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

(1) Due to the subjectivity inherent in the assumptions concerning the timing
    and nature of the uses of cash generated by the pro forma adjustments, cash
    flows from operating, investing and financing activities are not presented
    in the pro forma data.
   
(2) No historical earnings per share or share data are presented as the Company
    does not consider such data meaningful. Upon closing of the Offering, 100
    million shares of common stock will be outstanding and pro forma earnings
    per share data gives effect to these shares as if they were outstanding on
    January 1, 1997.     
(3) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. EBITDA is not intended to represent
    cash flows from operations and should not be considered as an alternative
    to net income as an indicator of the Company's operating performance or to
    cash flows as a measure of liquidity. The Company believes that EBITDA is a
    standard measure commonly reported and widely used by analysts, investors
    and other interested parties in the publishing and media industries.
(4) For purposes of the computations, earnings before fixed charges consist of
    income/(loss) before income taxes adjusted for equity earnings (loss), as
    appropriate, plus fixed charges. Fixed charges are defined as interest
    expense plus that portion of rental expense which is deemed to be
    representative of the interest factor. For the years ended December 31,
    1996, 1997 and Pro Forma 1997 earnings were insufficient to cover fixed
    charges by $26,598, $74,520 and $6,805, respectively.

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves various
risks. Prior to investing in the Common Stock being offered hereby,
prospective investors should consider carefully the factors set forth below,
together with the other information set forth in this Prospectus. Certain
information contained in this section and elsewhere in this Prospectus
contains forward-looking statements which involve risks and uncertainties. The
Company's actual results could differ materially from those anticipated in
these forward-looking statements as a result of certain factors set forth in
this section and elsewhere in this Prospectus.
 
RISKS RELATING TO THE REORGANIZATION
 
  The Company is a newly organized Delaware corporation, incorporated on
February 4, 1998 in contemplation of the Reorganization. As part of the
Reorganization, the Company has acquired and will acquire the MAC Assets for
approximately $370 million. Although the Company believes, based on an
independent appraisal of the assets, that the purchase price does not exceed
fair market value, such arrangements are not the result of an arm's length
negotiation between unrelated parties, and there can be no assurance that the
Company would not have been able to obtain better terms from unrelated
parties. See "The Reorganization," "Unaudited Pro Forma Combined Financial
Information," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Certain Transactions."
 
ABSENCE OF HISTORY AS A STAND-ALONE COMPANY; LIMITED RELEVANCE OF HISTORICAL
FINANCIAL INFORMATION
 
  The Company has never operated as a stand-alone company. Until October 1997,
the ZDI and the ZDCF businesses were managed as separate Softbank
subsidiaries. The Company's future operating results will depend in part on
its ability to integrate these businesses and manage the combined enterprise.
In addition, although the Company will be a subsidiary of Softbank following
the Offerings, Softbank will be under no obligation to provide assistance to
the Company or any of its subsidiaries.
 
  The financial information of ZDI and ZDCF included herein does not reflect
what the actual results of operations, financial position and cash flows of
the Company would have been had the Company existed and the Reorganization
been completed prior to the periods presented, nor is it necessarily
indicative of the results of operations, financial position and cash flows of
the Company in the future. The financial statements also include the MAC
Assets which are being transferred to the Company pursuant to the
Reorganization. See "Unaudited Pro Forma Combined Financial Information,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Presentation of Financial Information" and "Certain Transactions."
 
CONTROL BY PRINCIPAL STOCKHOLDERS AND POTENTIAL CONFLICTS OF INTEREST
   
  Upon the completion of the Reorganization, Softbank will own approximately
74.2% of the outstanding shares of Common Stock of the Company (71.4% if the
U.S. Underwriters' over-allotment option is exercised in full). As a result,
Softbank will be in a position to direct the election of all members of the
Board of Directors of the Company and to control even those actions that
require the approval of two-thirds or more of the voting share capital of the
Company, including amendments to the Company's Certificate of Incorporation
and any business combinations. Such concentration of ownership would also have
the effect of preventing a change in control of the Company that might
otherwise be beneficial to stockholders. Section 141 of the Delaware General
Corporation Law, however, imposes upon directors a fiduciary duty to
shareholders.     
   
  The Company and Softbank have entered into certain agreements governing
various interim and ongoing relationships between Softbank and the Company,
including certain licensing and management agreements relating to
publications, trade shows, ZDTV and ZDNet. In addition, Softbank has given the
Company an undertaking that, as long as it owns 40% of the voting stock of the
Company and can elect a majority of the Board of Directors, it will not expand
operations involving (x) publishing information on computing and Internet-
related technology through the media of print, CD-ROM/DVD, Internet and
television, or (y) producing trade shows, conferences, exhibitions and similar
events primarily related to computing and Internet-related technology outside
Japan in competition with the Company without the prior approval of the
Company's management
    
                                      12
<PAGE>
 
   
directors after consulting with the Company's independent directors. This
undertaking does not preclude investments by investment funds managed by
Softbank. Softbank manages certain venture capital funds which invest in,
among other things, computer and Internet-related companies. These funds may
be able to co-invest with the Company or compete with the Company with respect
to new investments. Softbank may develop new funds in the future, which funds
may compete with the Company for investment opportunities. The Company has
undertaken not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s Board of Directors and has agreed to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. Such arrangements and undertaking are not the result of an arm's length
negotiation between unrelated parties. See "--New Product Risks," "The
Company--Relationship with Softbank," "Certain Transactions," "Principal
Stockholders" and "Description of Capital Stock."     
 
SIGNIFICANT DEBT OBLIGATIONS
 
  At December 31, 1997, on a pro forma basis after giving effect to the
Reorganization described under "Unaudited Pro Forma Combined Financial
Information," the Company's total debt was approximately $1.594 billion, its
total stockholders' equity was approximately $1.441 billion, its earnings were
insufficient to cover fixed charges by $6.8 million and its total debt was
52.5% of total capitalization. The Company's indebtedness is substantial in
relation to its stockholders' equity. The degree to which the Company is
leveraged could have important consequences to holders of Common Stock
because: (i) the Company's ability to obtain additional financing in the
future for working capital, capital expenditures, acquisitions or general
corporate purposes may be impaired; (ii) the funds available to the Company
for its operations may be reduced if a substantial portion of the Company's
cash flow from operations is dedicated to the payment of principal and
interest on its indebtedness; and (iii) the Company's ability to incur
additional debt may be impaired because the Credit Facility and the Notes are
expected to contain 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. See "Description of Certain
Indebtedness." The indebtedness of the Company requires a substantial portion
of the Company's cash flow to be dedicated to the payment of principal and
interest on indebtedness, thereby reducing funds available for capital
expenditures and future business opportunities. In addition, the Company's
indebtedness could increase the Company's vulnerability to adverse general
economic conditions (including increases in interest rates) and could impair
the Company's ability to take advantage of significant business opportunities
that may arise.
 
DEPENDENCE ON DEMAND FOR ADVERTISING
   
  A significant portion of the Company's total revenue in 1997 (51.9%) was
derived from advertising sales. Should a general economic downturn or a
recession in the United States occur in the future, the Company's advertisers
may reduce their advertising budgets. In addition, technology product
advertisers may be affected by factors such as pricing pressures and new
product launches. Furthermore, there can be no assurance that technology
product advertisers will maintain current levels of advertising in special
interest magazines and events as opposed to general interest media such as
newspapers, television and Internet sites. Any material decline in the demand
for advertising by technology product advertisers could have an adverse effect
on the Company's financial condition and results of operations.     
 
IMPORTANCE OF CERTAIN PUBLICATIONS AND TRADE SHOWS
 
  Certain of the Company's publications have represented a significant portion
of the Company's historic revenue, and the Company expects that such
publications will continue to do so in the future. The Company's business
publications, which include such titles as PC Magazine, Computer Shopper and
PC Week, accounted for 49.0% of the Company's print publishing revenue in
1997. Although the Company believes it has a diversified portfolio of special-
interest publications and is not dependent on any single publication, a
significant decline in the performance of any of these publications could have
an adverse effect on the Company's financial condition and results of
operations. See "Business--Print Publishing--Sources of Print Publishing
Revenue."
 
  Certain of the Company's trade shows and conferences have represented a
significant portion of the Company's historic revenue, and the Company expects
that such trade shows and conferences will continue to
 
                                      13
<PAGE>
 
do so in the future. COMDEX/Fall accounted for 34.0% of the Company's trade
show and conference revenue in 1997. Although the Company believes it has a
diversified portfolio of trade shows worldwide, a significant decline in the
performance of COMDEX/Fall could have an adverse effect on the Company's
financial condition and results of operations. See "Business--Trade Shows and
Conferences--Sources of Trade Show and Conference Revenue."
 
SEASONALITY OF REVENUE; FLUCTUATIONS IN REVENUE FROM PERIOD TO PERIOD;
ANTICIPATED LOSS FOR FIRST QUARTER OF 1998
   
  The Company's business is seasonal, with revenue typically reaching its
highest level during the fourth quarter of each calendar year, largely due to
the timing of its single largest trade show event, COMDEX/Fall, and the
increase in publishing revenue in the fourth quarter due to increased consumer
buying activity during the holiday season. In 1997, 35.0% of the Company's
revenue was generated during the fourth quarter, with the first, second and
third quarters accounting for 19.5%, 26.1% and 19.4% of revenue, respectively.
In addition, the Company may experience fluctuations in revenue from period to
period based on levels of marketing expenditure by the Company's advertising
customers and by competition among computer technology marketers. Many of the
Company's large customers concentrate their advertising expenditures around
major new product launches. Marketing expenditure by technology companies can
also be affected by factors affecting the computer industry generally,
including changes in end user demand, pricing pressures and inventory
surpluses. Furthermore, the Company's results are affected by the number and
timing of new product launches and the timing of events. The launch of new
publications, trade shows and services are funded with cash flow from
operations and are expensed as incurred. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Overview" and "--
Seasonality."     
   
  For the first quarter of 1998, the Company expects that its net loss will
increase by 15-20% as compared with the first quarter of 1997. There are
several factors influencing the lower operating results anticipated for the
first quarter of 1998, including lower advertising revenue in the Company's
business publications as a result of factors affecting the computer technology
industry generally (substantially offset by revenue from trade shows which
were not held in the comparable period of the prior year) and certain one-time
costs occurring in the first quarter of 1998. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Three Months Ended
March 31, 1998 Compared With Three Months Ended March 31, 1997 (unaudited)."
    
HISTORICAL NET LOSSES
   
  The Company had net losses of $52.1 million and $71.2 million for the twelve
months ended December 31, 1996 and 1997, respectively. On a pro forma as
adjusted basis giving effect to the Reorganization, the Company had a net loss
of $7.9 million, or $(.08) per share, for the twelve months ended December 31,
1997. See "Unaudited Pro Forma Combined Financial Information." There can be
no assurance that the Company will report net income in the future.     
 
NEW PRODUCT RISKS
 
  The Company's future success will depend in part on its ability to monitor
rapidly changing technologies and market trends and offer new publications,
trade shows and services that address the needs of specific target audiences.
The process of internally researching and developing, launching, acquiring
acceptance and establishing profitability for a new publication, trade show or
service, or assimilating and marketing an acquired publication, trade show or
service, can be risky and costly. There can be no assurance that the Company's
efforts to introduce new or assimilate acquired publications, trade shows or
services will be successful or profitable. In addition to its publications,
trade shows and services, the Company is a leading provider of Internet
content about computing services, primarily through its ZDNet online service.
The Internet is still in the relatively early stages of development;
therefore, there can be no assurance that the Company's Internet services will
remain competitive. Costs related to the development of new products are
expensed as incurred and, accordingly, the Company's profitability from year
to year may be adversely affected by the number and timing of new product
launches. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
  The Company has entered into a license and services agreement with MAC to
develop ZDTV. ZDTV is owned by MAC, but as part of this license and services
agreement MAC has granted the Company an option
 
                                      14
<PAGE>
 
exercisable through December 31, 1998 to purchase all of MAC's interest in
ZDTV for an amount equal to MAC's investment plus 10% per annum for the period
of its investment. The Company does not intend to exercise the option unless
ZDTV has secured sufficient cable carriage. This may include entering into a
joint venture or other co-ownership arrangement. The Company is currently
funding ZDTV's operations on behalf of MAC through unsecured advances which,
for approved levels of expenditure, are to be reimbursed by MAC. ZDTV's cash
requirements are expected to be approximately $54 million in 1998. There can
be no assurance that MAC will continue to approve and reimburse the Company
for expenditures or that the Company will exercise its option. If the Company
exercises its option, there can be no assurance that ZDTV will ultimately
obtain sufficient cable carriage and commercial acceptance to be profitable.
See "The Company--Relationship with Softbank" and "Certain Transactions."
 
RISKS ASSOCIATED WITH FLUCTUATIONS IN PAPER AND POSTAGE COSTS
 
  The Company's principal raw material is paper. Paper costs constitute a
significant expense, accounting for 15.2% of the Company's total U.S. print
publishing operating expenses in 1997. Paper prices have been volatile over
the past several years, initially rising in 1994, rising more significantly in
1995 and 1996 and declining in 1997. Management anticipates paper prices will
increase in 1998. The Company does not use forward contracts and most of its
paper supply contracts, which are generally for a two to three year renewable
term, provide for price adjustments to reflect changing market prices.
Accordingly, significant increases in paper prices could adversely affect the
Company's future results of operations.
 
  Postage for magazine distribution is also a significant expense for the
Company, accounting for 11.3% of the Company's total U.S. print publishing
operating expenses in 1997. Postage costs increase periodically and can be
expected to increase in the future. The United States Postal Service has
recently announced a 5.4% increase for commercial magazine rates, which is
expected to become effective in 1998. The Company may not be able to recover,
in whole or in part, paper or postage cost increases. Accordingly, significant
cost increases could have an adverse effect on the Company's financial
condition or results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business--Print
Publishing--Paper and Printing."
 
COMPETITION
   
  The Company faces significant competition with respect to its print
publications, trade shows and conferences and other technology information
services. In its publishing business, the Company principally competes for
advertising and circulation revenue with publishers of other computer
technology publications and also faces broad competition from media companies
that produce general interest magazines, newspapers and online content.
Overall competitive factors include product positioning, editorial quality,
circulation, price and customer service. Competition for advertising dollars
is primarily based on advertising rates, the nature and scope of readership,
reader response to advertisers' products and services and the effectiveness of
sales teams. In its trade show and conference business, the Company competes
with other producers of trade shows and conferences for exhibition space,
exhibitors and attendees, primarily on the basis of the quality of the
conference, its content and organizational efficiency. If the Company is
unable to compete effectively for advertisers, readers, exhibitors and/or
attendees, its financial condition and results of operations could be
adversely affected. See "Business--Competition."     
 
CONSOLIDATION OF PRINCIPAL VENDORS; SIGNIFICANT SUPPLIER
 
  The Company's principal vendors include paper suppliers, printers,
fulfillment houses and national newsstand distributors. Each of these
industries is currently experiencing consolidation among their principal
participants. Such consolidation may result in: (i) decreased competition,
which may lead to increased prices; (ii) interruptions and delays in services
provided by such vendors; and (iii) greater dependence on certain vendors.
Such factors could adversely affect the Company's results of operations. One
printing company
 
                                      15
<PAGE>
 
accounted for approximately 50% of the Company's total print publishing
manufacturing expenditures in 1997 for its U.S.-based publications. While the
Company believes there are adequate alternatives available, an interruption or
delay in service from, or the loss of, this printer could have an adverse
effect on the Company. See "Business--Print Publishing--Paper and Printing."
 
RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION
 
  One component of the Company's growth strategy is to further expand into
international markets. There are certain risks inherent in doing business in
international markets, such as the uncertainty of product acceptance by
different cultures, the risks of divergent business expectations or
difficulties in establishing joint ventures with foreign partners,
difficulties in staffing and managing multinational operations, currency
fluctuations, state-imposed restrictions on the repatriation of funds and
potentially adverse tax consequences. There can be no assurance that one or
more of such factors will not have an adverse effect on the Company's future
international operations and, consequently, on the Company's financial
condition and results of operations. See "Business --Print Publishing--
International Publications" and "Business--Trade Shows and Conferences."
 
SHARES ELIGIBLE FOR FUTURE SALE
   
  Upon completion of the Offering, the Company expects to have 100 million
shares of Common Stock outstanding (approximately 103.9 million shares if the
U.S. Underwriters' over-allotment option is exercised in full), of which the
25.8 million shares offered hereby will be freely tradeable without
restriction by persons other than "affiliates" of the Company. The remaining
shares of Common Stock will be deemed "restricted" securities within the
meaning of the Securities Act of 1933, as amended (the "Securities Act"), and
as such may not be sold in the absence of registration under the Securities
Act or an exemption therefrom, including the exemption contained in Rule 144
under the Securities Act. The Company and Softbank have entered into a
registration rights agreement in connection with the Offering which provides
Softbank with the right to require the Company to register any or all of the
Common Stock held by Softbank in a public offering pursuant to the Securities
Act and the right to "piggyback" or include Softbank's Common Stock in any
registration of Common Stock made by the Company. No prediction can be made as
to the effect, if any, that future sales of shares of Common Stock, or the
availability of such shares for future sales, will have on the market price of
the shares of Common Stock prevailing from time to time. Sales of substantial
amounts of Common Stock, or the perception that such sales could occur, could
adversely affect prevailing market prices for the Common Stock, and such a
reduction in the market price of the Common Stock could impair the ability of
the Company to raise additional capital through future public offerings of its
equity securities. See "Shares Eligible for Future Sale."     
 
DIVIDEND POLICY; HOLDING COMPANY STRUCTURE
 
  The Company currently intends to retain earnings to finance its operations,
fund future growth and reduce indebtedness and does not anticipate paying
dividends in the foreseeable future. In addition, as a holding company, the
Company's major assets will initially be the shares it holds in its
subsidiaries. Therefore, the Company's ability to pay future dividends and
distributions, if any, to holders of the Common Stock is dependent upon the
receipt of dividends or other payments from its subsidiaries. See "Dividend
Policy."
 
SUBSTANTIAL AND IMMEDIATE DILUTION
   
  The initial public offering price of the Common Stock will be higher than
the book value per share of Common Stock. Accordingly, purchasers in the
Offering will suffer a substantial and immediate dilution of $31.39 in the net
tangible book value per share of Common Stock from the initial public offering
price. See "Dilution."     
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
  Prior to the Offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market for
the Company's Common Stock will develop or be sustained after
 
                                      16
<PAGE>
 
the Offering. The initial public offering price will be determined by
negotiation between the Company and the representatives of the Underwriters
based upon several factors. See "Underwriters" for a discussion of the factors
to be considered in determining the initial public offering price. The trading
price of the Company's Common Stock could be subject to wide fluctuations in
response to quarterly variations in operating results, expectations of
securities analysts, announcements of new publications or technological
innovations by the Company or its competitors, changes in financial estimates
by securities analysts, the operating and stock price performance of other
companies that investors may deem comparable to the Company and other events
or factors. In addition, the stock market in general has experienced extreme
volatility that often has been unrelated to the operating performance of
particular companies which are traded on the market. These broad market and
industry fluctuations may adversely affect the trading price of the Company's
Common Stock, regardless of the Company's actual operating performance.
 
CERTAIN ANTI-TAKEOVER EFFECTS
 
  Certain provisions of the Company's Certificate of Incorporation and By-Laws
may inhibit changes in control of the Company not approved by the Board of
Directors. The Company will also be afforded the protections of Section 203 of
the Delaware General Corporation Law, which could have similar effects. See
"Description of Capital Stock."

                                  THE COMPANY
 
  The Company is the world's preeminent integrated media and marketing company
focused on computing and Internet-related technology, with principal platforms
in print publishing, trade shows and conferences, online content, market
research and education. The Company's 28 primary U.S. and international
titles, including its joint ventures, and over 50 licensed publications, total
more than 80 publications distributed worldwide, with a combined circulation
of more than eight million primary readers. The Company's predecessor was
founded in 1927 and pioneered the development of special-interest magazines,
including Car and Driver, Popular Photography, Stereo Review, Boating, Skiing
and Modern Bride. The Company also produces the world's most important trade
shows related to computer technology, with over two million estimated
attendees at over 50 trade shows and conferences worldwide in 1997. The
Company's COMDEX/Fall event is the number one ranked trade show for all
industries in the U.S. as measured by total revenue, total exhibit space and
number of attendees. The Company's ZDNet.com Web site is the leading computing
content site and ranked the number one Web site in 1997 in the category of
news, information and entertainment, as measured by visitors per month. The
Company's other media and marketing platforms include market research,
education and the publication of computer-related newsletters, training
manuals and materials.
 
  The Company's principal executive offices are located at One Park Avenue,
New York, New York 10016 and its telephone number is (212) 503-3500.
 
RELATIONSHIP WITH SOFTBANK
   
  The Company is an indirect subsidiary of SOFTBANK Corp., which, as of
December 31, 1997, was 50.2% owned by Mr. Masayoshi Son, its President,
including 43.4% directly held by his 99% owned holding company, MAC. Softbank
is a leading provider of information and distribution services as
infrastructure for the digital information industry. Softbank is Japan's
leading distributor of computer software as well as a leading publisher of
Japanese computer technology publications. It also is an 80% owner of Kingston
Technology Company ("Kingston"), one of the world's largest independent
providers of computer memory modules; a founder and co-owner of Japan Sky
Broadcasting Co., Ltd. ("JSkyB"), a digital satellite broadcasting venture in
Japan; a shareholder, directly or through its investment fund affiliates, in
over 50 network and computer-related venture businesses in the digital
information industry; and a 29.4% owner of Yahoo! Inc.     
   
  Upon the completion of the Reorganization, Softbank will own approximately
74.2% of the outstanding shares of Common Stock (71.4% if the U.S.
Underwriters' overallotment is exercised in full). The Company and Softbank
have entered into certain agreements governing various interim and ongoing
relationships between Softbank and the Company, including certain licensing
and management agreements relating to publications, trade shows, ZDTV and
ZDNet. See "Certain Transactions."     
   
  In addition, Softbank has given the Company an undertaking that, as long as
it owns 40% of the voting stock of the Company and can elect a majority of the
Board of Directors, it will not expand operations involving (x) publishing
information on computing and Internet-related technology through the media of
print, CD-ROM/DVD, Internet and television, or (y) producing trade shows,
conferences, exhibitions and similar events primarily related to computing and
Internet-related technology outside Japan in competition with the Company
without the prior approval of the Company's management directors after
consulting with the Company's independent directors.     
 
  This undertaking does not preclude investments by investment funds managed
by Softbank. Softbank manages certain venture capital funds which invest in,
among other things, computer and Internet-related companies. These funds may
be able to co-invest with the Company or compete with the Company with respect
to new investments. Softbank may develop new funds in the future, which funds
may compete with the Company for investment opportunities. The Company has
undertaken not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s Board of Directors and has agreed to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest" and "Certain Transactions."
 
                                      18
<PAGE>
 
   
  In order to expand its media platforms, the Company has entered into a
license and services agreement with MAC to develop ZDTV, a 24-hour cable
television channel and integrated Web site focused exclusively on computers,
technology and the Internet. ZDTV is owned by MAC, but as part of this license
and services agreement MAC has granted the Company an option exercisable
through December 31, 1998 to purchase all of MAC's interest in ZDTV for an
amount equal to MAC's investment plus 10% per annum for the period of its
investment. Pursuant to the license and services agreement, the Company has
agreed to fund ZDTV's operations on behalf of MAC through unsecured advances
which, for approved levels of expenditure, are to be reimbursed by MAC. Such
advances bear interest at the 30-day LIBOR rate plus .50%. ZDTV's cash
requirements are expected to be approximately $54 million in 1998. The
Company's cumulative advances in respect of ZDTV, which totaled $14.4 million
net of $10.1 million in repayments through December 31, 1997, will be repaid
concurrently with the Reorganization. The Company has not yet determined
whether it will exercise its option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon securing sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Company. ZDTV is not included in the
Company's results of operations. See "Certain Transactions."     
 
                                      19
<PAGE>
 
                              THE REORGANIZATION
   
  The businesses to be conducted by the Company were acquired in a series of
acquisitions and internal reorganizations undertaken by Softbank. See "The
Company--Relationship with Softbank." The Company's principal business
operations are as follows:     
 
    (i) the computer technology publishing operations of Ziff-Davis
  Publishing Company ("ZD Pubco"), which Softbank acquired in February 1996
  for $1.8 billion in cash and subsequently renamed Ziff-Davis Inc.;
 
    (ii) the COMDEX computer-related trade show operations ("COMDEX"), which
  Softbank acquired in April 1995 for $803 million in cash and renamed
  SOFTBANK COMDEX Inc. ("SB COMDEX"); and
 
    (iii) the computer and network-related trade show operations of Ziff-
  Davis Exposition and Conference Company ("ZD Expos"), which Softbank
  acquired in December 1994 for $127 million in cash and subsequently renamed
  SOFTBANK Forums Inc. ("SB Forums").
 
  Concurrently with the ZD Pubco and ZD Expos acquisitions described above,
MAC purchased certain operations and assets of these companies for $302
million and $75 million, respectively. The MAC Assets consist of certain
international consumer and Internet publications, international trade shows
and the ZDNet business, most of which were still under development. The MAC
Assets and related operations have been managed by ZDI and ZDCF since their
acquisition by MAC. As part of the Reorganization discussed below, the MAC
Assets, except for those that have been discontinued, have been or will be
acquired by the Company at a purchase price that does not exceed fair market
value, based on an independent appraisal. A portion of the MAC Assets was
acquired by the Company on October 31, 1997 for $100 million, and the balance
will be sold to the Company concurrently with the Offerings. See "Use of
Proceeds."
   
  In October 1997, Softbank decided to combine the businesses of ZDI, SB
COMDEX and SB Forums. SB Forums and SB COMDEX were merged as of December 31,
1997, with the surviving corporation named ZDCF. In order to complete the
combination and establish the Company as a separate public company,
concurrently with the sale of the Company's Common Stock offered hereby, ZDI
and ZDCF will be contributed to the Company in exchange for 74.2% of the
Company's Common Stock, and approximately $928 million of the Company's
obligations to Softbank will be converted to equity at the initial public
offering price. The amount of intercompany indebtedness to be converted to
equity is comprised of the obligations due to Softbank as of December 31,
1997, except those repaid with borrowings under the Credit Facility and the
proceeds of the Notes Offering and a $94.2 million note which matures on
February 20, 2009. Assuming an initial public offering price of $15.50 per
share, the value of the capitalized intercompany indebtedness would have been
equivalent to 59.8 million shares of Common Stock. In addition, the Company
will receive approximately $10 million of fixed assets from Kingston in
exchange for $10 million of shares of the Company's Common Stock (valued at
the initial public offering price), which assets will be subsequently leased
back to Kingston.     
   
  As part of the Reorganization, the Company will: (i) issue 25.8 million
shares of its Common Stock in the Offering; (ii) sell $250 million aggregate
principal amount of its    % Senior Subordinated Notes due 2008 in the Notes
Offering; and (iii) enter into the $1.35 billion Credit Facility and borrow
$1.25 billion thereunder. The Company will use the net proceeds from the
Offerings and the Credit Facility to (i) pay $270 million to MAC, representing
the purchase price for the remaining MAC Assets, and (ii) repay approximately
$1.589 billion of obligations to Softbank (including the Company's liability
to Softbank with respect to the $100 million purchase price for the initial
portion of the MAC Assets, net of the approximately $42 million of balances
due from MAC in connection with funding for the MAC Assets and ZDTV through
December 31, 1997), which payment will eliminate all except $94.2 million of
the remaining intercompany indebtedness as of December 31, 1997. The Company
has obtained a commitment letter from The Bank of New York, Morgan Stanley
Senior Funding, DLJ Capital Funding and The Chase Manhattan Bank to provide
such Credit Facility.     
 
  Unless the context otherwise indicates, references herein to the
"Reorganization" include all of the transactions described above. The
Offerings will be conditioned upon the completion of all such transactions
comprising the Reorganization, which shall be deemed to occur simultaneously.

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the Common Stock and the
Notes are estimated to be $377.5 million ($434.5 million if the U.S.
Underwriters' over-allotment option is exercised in full) and $241.3 million,
respectively, after deducting underwriting discounts and commissions and
estimated offering expenses payable by the Company. The Company intends to use
the proceeds from the Offerings and approximately $1.25 billion in borrowings
under the Credit Facility, to fund the approximately $270 million purchase
price of the balance of the MAC Assets (see "Risk Factors--Risks Relating to
the Reorganization") and repay approximately $1.589 billion of intercompany
obligations.

                                DIVIDEND POLICY
   
  The Company currently intends to retain all of its earnings following the
Offering in order to finance its operations, repay indebtedness and fund
future growth and, accordingly, does not expect to pay any dividends for the
foreseeable future. The Board of Directors will review this dividend policy
from time to time in light of the conditions then existing, including the
Company's financial condition, results of operations, capital requirements,
restrictions, if any, contained in financing or other agreements binding upon
the Company, and such other factors as the Board of Directors deems relevant.
The Credit Facility and provisions of the Notes contain certain limitations on
the payment of dividends. See "Risk Factors--Dividend Policy; Holding Company
Structure" and "Description of Certain Indebtedness--Notes" and "--Credit
Facility."

                                   DILUTION
   
  As of December 31, 1997 the pro forma net tangible book value of the Company
was a deficit of $1.97 billion or $26.50 per share of Common Stock. Pro forma
net tangible book value per share is determined by dividing the tangible net
worth of the Company (total assets less intangible assets and total
liabilities) by the aggregate number of shares of Common Stock outstanding,
assuming the Reorganization had taken place on January 1, 1997. After giving
effect to the sale of the 25.8 million shares of Common Stock offered hereby
(at an assumed initial offering price of $15.50 per share, the mid point of
the range set forth on the cover page of this Prospectus) and the application
of the net proceeds therefrom, pro forma net tangible book value of the
Company as of December 31, 1997 would have been a deficit of approximately
$1.59 billion, or $15.89 per share. This represents an immediate increase in
pro forma net tangible book value of $10.61 per share to Softbank, the current
stockholder of ZDI and ZDCF, and an immediate dilution in pro forma net
tangible book value of $31.39 per share to purchasers of Common Stock in the
Offering. The following table illustrates the per share dilution in pro forma
net tangible book value to new investors:

  The following table summarizes, on a pro forma basis, as of December 31,
1997, the number of shares of Common Stock purchased from the Company, the
total consideration paid (or to be paid) and the average price per share paid
(or to be paid) by the Company's existing stockholder and by new investors
purchasing shares of Common Stock in the Offering, based on an assumed initial
public offering price of $15.50 per share, before deducting estimated offering
expenses and underwriting discounts and commissions.

(1) Historical Combined Financial and Other Data of ZDI has been presented for

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

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

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

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 the Company's new
product launches and launches in new markets, as well as by acquisitions. New
publications generally require several years to achieve profitability and upon
achieving initial profitability, often have lower margins than more
established publications. The launch of new publications, trade shows and
services are funded with cash flow from operations and are expensed as
incurred. Accordingly, the Company's revenue from year to year may be affected
by the number and timing of new product launches. If the Company concludes
that a new publication, trade show or service will not achieve certain
milestones with regard to revenues, profitability and cash flow within a
reasonable period of time, management may discontinue such publication, trade
show or service or merge it into another existing publication, trade show or
service. See "Risk Factors--New Product Risks."     
 
  Historically, the financing requirements of the Company have been funded
through intercompany loans and advances, totaling $2.5 billion at December 31,
1997, of which $126 million was current. As a result of the Reorganization,
the Company's intercompany debt owed to Softbank will be reduced to $94.2
million. Such indebtedness bears interest at 9.9% and matures in February
2009. Concurrently with the Offering, the Company intends to issue and sell
$250 million aggregate principal amount of Notes and will enter into the $1.35
billion Credit Facility and borrow $1.25 billion thereunder. See "--Liquidity
and Capital Resources."
 
PRESENTATION OF FINANCIAL INFORMATION
 
  ZD Inc. was incorporated on February 4, 1998. Concurrent with the completion
of the Offerings, all of the common stock of ZDI and ZDCF, the Company's
principal operating subsidiaries, will be contributed to the Company.
 
  These subsidiaries were acquired in a series of acquisitions and internal
reorganizations undertaken by the Company's principal stockholder, Softbank.
In December 1994, Softbank acquired SB Forums for $127 million in cash. The
acquisition was accounted for using the purchase method of accounting and
accordingly, the results of operations of SB Forums are included in the
Combined Financial Statements of ZDI and ZDCF for 1995, 1996 and 1997.
 
  In April 1995, SOFTBANK acquired SB COMDEX for $803 million in cash, plus
transaction costs. The acquisition was accounted for using the purchase method
of accounting and accordingly, SB COMDEX's results are included in the
Combined Financial Statements since the date of acquisition. As of December
31, 1997, SB Forums and SB COMDEX were merged, with the surviving corporation
named ZD Comdex and Forums (ZDCF).
 
  In February 1996, Softbank acquired Ziff-Davis Publishing Company
(subsequently renamed Ziff-Davis Inc.) for $1.8 billion in cash. The
acquisition of ZDI has been accounted for using the purchase method of
accounting and accordingly, the results of ZDI are included in the Combined
Financial Statements since the date of acquisition. ZDI's results of
operations for periods prior to the date of acquisition are set forth in the
ZDI Financial Statements included elsewhere in this Prospectus.
 
  In connection with the acquisition of SB Forums and ZDI described above,
MAC, Softbank's largest shareholder, purchased certain operations and assets
of these companies for $75 million and $302 million, respectively. The MAC
Assets consist of certain international publications, consumer and Internet
publications, international trade shows and the ZDNet business, most of which
were still under development. As part of the Reorganization, the MAC Assets,
except for those which have been discontinued, have been or will be sold to
the Company. The acquisition of the MAC Assets has been accounted for in a
manner similar to a pooling of interests and is reflected in the Combined
Financial Statements of ZDI and ZDCF for all periods presented.
 
  Due to the acquisition of ZDI on February 29, 1996 and the resulting
revaluation of assets and liabilities and the change in the Company's capital
structure, the historical financial statements of ZDI and ZDCF are not
directly comparable. The table below presents the Company's pro forma results
for 1996 and 1995 as if ZDI and ZDCF had been under common control since
January 1, 1995. The results of SB COMDEX are included since
 
                                      31
<PAGE>
 
April 1, 1995. The combined results for 1995 and 1996 were derived by
combining the statement of operations for ZDI for the year ended December 31,
1995 and for the period January 1, 1996 to February 28, 1996 with the combined
statement of operations for ZDI and ZDCF for the years ended 1995 and 1996. In
addition, the purchase accounting adjustments related to the 1996 acquisition
of ZDI have been reflected as of January 1, 1995 resulting in pro forma
amortization, interest and income tax provision adjustments. Such adjustments
are further described in note (a) to the table set forth below under "--
Results of Operations." No pro forma adjustments have been made related to the
acquisition of SB COMDEX as such adjustments are not material. Although such
combination is not in accordance with generally accepted accounting
principles, management believes the combined statements present the most
meaningful basis of comparison. Intercompany transactions for those periods
were immaterial. The financial information presented herein may not
necessarily reflect the results of operations which would have occurred had
the Company been a stand-alone entity.

January 1, 1995.

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

THREE MONTHS ENDED MARCH 31, 1998 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1997 (UNAUDITED)
   
  For the first quarter of 1998, the Company expects to report approximately
the same level of revenue as compared with the first quarter of 1997. Revenue
from publishing operations will decline approximately 5% primarily due to the
absence of over $12 million of revenue from Macuser and MacWeek magazines,
which were transferred in October 1997 to a 50/50 joint venture with another
publishing company and are no longer consolidated in the Company's results.
The publishing segment will also record lower advertising revenue from its
business publications principally as a result of factors affecting the
computer technology industry generally, including slowing demand for computer
products, fewer new product launches, pricing pressures, vendor market share
shifts and excess PC inventories in distribution channels. This decline will
be largely offset by increased advertising sales in the Company's Internet
business and consumer publications. More than offsetting the decline in
publishing revenue will be an increase of approximately 75% in revenue from
the Company's tradeshows and conferences operations, primarily the result of
earlier production of two events in the first quarter of 1998 that had been
held in the second quarter of 1997.     
   
  The Company expects the net loss for the first quarter to increase by 15-20%
as compared with the first quarter of 1997 and expects EBITDA to decline 40-
45%. The unfavorable variances are primarily due to the lower level of
advertising in business publications, which have higher profit margins than
consumer publications or the Internet business, coupled with approximately
$3.4 million of one-time costs for office relocations and $1.8 million of
expenses incurred in launching two new publications.     
   
  As indicated below under "Seasonality," the first quarter accounted for
approximately 19.4% and 19.5% of the Company's revenue in 1996 on a pro forma
basis and 1997, respectively, and approximately 12.0% and 9.4% of the
Company's EBITDA for the respective years.     
 
YEAR ENDED DECEMBER 31, 1997 COMPARED WITH PRO FORMA YEAR ENDED DECEMBER 31,
1996
 
 Revenue
 
  Revenue increased by $73.2 million or 6.8% from $1,080.6 million in 1996 to
$1,153.8 million in 1997.
 
  Revenue from publishing grew by $50.5 million or 6.2% from $815.7 million to
$866.2 million. Approximately $22 million was due to inclusion of a full year
of results for the electronic gaming publications acquired in mid-1996 and two
publications launched in late 1996. Revenue from Internet services increased
$13.5 million or 71.9% due to higher advertising volume attributable to the
Company's growing presence on the Internet. Increases in advertising rates,
generally ranging between 3% and 10%, and a 5.1% increase in advertising pages
contributed $11.5 million. Revenue from international operations, which
generated 10.2% of the segment's revenue, decreased by $6.6 million due to the
strengthening of the U.S. dollar relative to the major European currencies.
Continued growth from new educational product launches and sales of market
research studies accounted for the balance of the revenue growth.
 
  Revenue from trade shows and conferences increased $22.6 million or 8.5%
from $264.9 million to $287.5 million. Approximately $15 million of the
increase was due to 11 new trade show launches, including revenue from
ancillary show-related sources. The balance of revenue growth was due to
higher exhibitor rates charged at the major events, partly offset by a decline
in revenue from COMDEX/Spring and certain U.K. events.
 
 Cost of production
 
  Production costs increased $22.6 million or 7.5% from $302.6 million to
$325.2 million.
 
  Publishing production costs increased $10.4 million or 4.8% from $215.3
million in 1996 to $225.7 million. Costs related to new launches and volume-
related growth increased approximately $20 million but were partly offset by
approximately $10 million of lower paper costs.
 
  The costs of producing trade shows and conferences increased $12.2 million
or 14.0% from $87.3 million to $99.5 million primarily as a result of costs
related to new events launched in 1997.
 
                                      33
<PAGE>
 
 Selling, general and administrative expenses
 
  Selling, general and administrative expenses increased $35.7 million or 6.8%
from $528.6 million to $564.3 million. The increase was due to the addition of
employees to support base business volume growth and launches of new products
and services. Results included a one-time $6.0 million charge for the
consolidation and restructuring of the trade shows and conferences business
which was announced in the fourth quarter of 1997. Costs for the publishing
segment rose 4.2% while those for the trade shows and conferences segment rose
22.1% due to the number of new launches and the one-time restructuring charge.
 
 Depreciation and amortization
 
  Total depreciation and amortization decreased $6.3 million to $154.9 million
in 1997. The reduction in depreciation and amortization expense was a result
of certain assets being fully depreciated in 1996.
 
 Interest expense, net
 
  Net interest expense increased $54.9 million or 40.5% to $190.4 million in
1997 due to interest on an additional $900 million of intercompany
indebtedness to Softbank incurred to finance a return of capital.
 
 Other non-operating income, net
 
  Other non-operating income/expense primarily reflects the Company's equity
share of earnings and losses from joint ventures and fees earned from
management of trade shows and conferences not produced by the Company. Income
increased $2.6 million from $6.1 million in 1996 to $8.7 million or 42.6%
reflecting growth in fees from managed events and reduced losses from joint
ventures.
 
 Income Taxes
 
  The 1997 combined income tax benefit of $1.3 million compares to a pro forma
income tax provision of $25.7 million in 1996. The improvement in the tax
provision is due to a higher pre-tax loss giving rise to a tax benefit. The
difference between the 1997 and 1996 effective tax rates and the federal
statutory tax rate of 35.0% is primarily due to non-recognition of tax losses
generated by the MAC Assets ($56.9 million and $77.2 million in 1997 and 1996,
respectively), non-deductible goodwill amortization ($10.2 million and $8.6
million, respectively) and state and local income taxes. In addition, the 1996
tax provision increased approximately $3.2 million as a result of pro forma
adjustments related to the ZDI acquisition.
 
 Net loss
   
  As a result of the 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%.
Excluding the one-time charge related to the consolidation and restructuring
of the trade shows and conferences business, the 1997 ratio would have been
24.2%.
 
PRO FORMA YEAR ENDED DECEMBER 31, 1996 COMPARED WITH PRO FORMA YEAR ENDED
DECEMBER 31, 1995
 
 Revenue
 
  Revenue increased by $108.9 million or 11.2% from $971.7 million in 1995 to
$1,080.6 million in 1996.
 
  Revenue from publishing grew by $46.7 million or 6.1% from $769.0 million to
$815.7 million. Higher overall advertising rates combined with a 12.4% growth
in advertising pages contributed 47.5% of the revenue increase while the mid-
1996 acquisition of several electronic gaming publications accounted for 33.5%
of the increase. New educational product launches and growth in sales of
market research studies accounted for the balance of revenue growth. Internet
revenue was slightly below the prior year due to the transition from a
business based on membership and subscription fees to one which is supported
primarily by advertising.
 
                                      34
<PAGE>
 
  Revenue from trade shows and conferences increased $62.2 million or 30.7%
from $202.7 million to $264.9 million. The launch of new international trade
shows accounted for 36.7% of the growth while the introduction of customized
events contributed 19.8%. The balance of the increase was due to growth in
exhibitor square footage and rates at the Company's major U.S. shows.
 
 Cost of production
 
  Production costs increased $40.2 million or 15.3% from $262.4 million to
$302.6 million.
 
  Publishing production costs increased $21.6 million or 11.2% from $193.7
million to $215.3 million, primarily due to volume-related growth and higher
paper costs. Approximately 31.5% of the increase was attributed to costs for
the magazines acquired mid-year while increased frequencies on certain
publications and a full year of costs for publications launched in late 1995
accounted for 18.1% of the increase.
 
  The costs of producing trade shows and conferences increased $18.6 million
or 27.0% from $68.8 million to $87.4 million. The increase was driven by the
cost of new product launches as well as higher direct marketing and facility-
related fees for the major U.S. events.
 
 Selling, general and administrative expenses
 
  Selling, general and administrative expenses rose $53.6 million or 11.3%
from $475.0 million to $528.6 million. This increase reflects the addition of
employees to support growth in the base business along with the launches of
new products and services. Costs for the publishing segment rose 6.1% while
those for the trade shows and conferences segment rose 58.7%, reflecting a
higher level of new launches and the absence of COMDEX related expenses for
the first three months of 1995 (COMDEX was acquired April 1, 1995).
 
 Depreciation and amortization
 
  Total depreciation and amortization of $161.3 million increased $7.1 million
from $154.2 million in 1995 primarily due to the inclusion of a full year's
depreciation and amortization relating to SB COMDEX, which was acquired April
1, 1995.
 
 Interest expense, net
 
  Net interest expense increased $2.4 million or 1.8% on a pro forma basis due
to higher average debt levels in 1996.
 
 Other non-operating income, net
 
  Income increased to $6.1 million compared to $.8 million in 1995 due to the
growth in fees from managed events along with reduced losses from joint
ventures.
 
 Income Taxes
 
  The combined income tax provision of $25.7 million compares to an income tax
provision of $9.6 million in 1995. The unfavorable variance in income taxes
and the difference in the 1996 and 1995 effective tax rates from the federal
statutory tax rate of 35% is primarily attributable to non-recognition of tax
losses generated by the MAC Assets ($77.2 million in 1996) and non-deductible
goodwill amortization ($8.6 million in 1996). In addition, the tax effects of
the 1996 and 1995 pro forma adjustments relating to the ZDI acquisition were a
$3.2 million and $11.9 million increase in tax provision, respectively.
 
 Net Loss
   
  As a result of the changes described above, net loss for the period
increased $5.2 million or 8.4% from $61.8 million to $67.0 million.     
 
                                      35
<PAGE>
 
 EBITDA
 
  EBITDA for 1996 was $255.4 million, an increase of $20.3 million or 8.7%
from the $235.1 million generated in 1995. The increase was due to higher
revenue and management fee income, net of higher production costs and selling,
general and administrative expenses. The cost of new product launches caused
the growth rate of expenses to exceed the revenue growth rate and, as a
result, the ratio of EBITDA to revenue of 23.6% decreased slightly from 24.2%
for 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Historically, the financing requirements of the Company have been funded
through intercompany loans and advances.
 
  As a result of the Reorganization, the Company's intercompany debt owed to
Softbank will be reduced to $94.2 million. Such indebtedness bears interest at
9.9% and matures in February 2009. Concurrently with the Offering, the Company
intends to issue and sell $250 million aggregate principal amount of Notes. In
addition, the Company will enter into the $1.35 billion Credit Facility, and
borrow $1.25 billion thereunder, to provide additional funds for the repayment
of intercompany debt to Softbank and to provide for the Company's working
capital requirements. The Credit Facility will consist of a $700 million
reducing revolving credit facility (with $600 million drawn at closing) and a
$650 million term loan, both of which will mature in March 2005. There will be
no scheduled reductions in the revolving credit commitment or amortization
under the term loan until September 2000.
 
  Cash and cash equivalents were $30.3 million and $29.9 million at December
31, 1997 and 1996, respectively. The balance increased $.4 million due to the
factors discussed below:
 
  Cash (used) provided by operating activities was $(3.4) million and $65.7
million for the years ended December 31, 1997 and 1996, respectively. The
decrease from 1996 to 1997 was the result of higher interest expense and final
payment of long-term incentives to management established in connection with
the sale of ZDI in 1994.
 
  For the year ended December 31, 1997, the Company used $44.2 million in cash
for investing activities, principally $30.2 million in capital expenditures.
The majority of these expenditures were for computer equipment and leasehold
improvements. The Company believes that future capital expenditures associated
with new office space will be approximately $35 million in 1998 and $25
million in 1999 (net of tenant improvement credits). Cash used for investing
activities on a pro forma basis for 1996 was $66.8 million principally due to
capital expenditures of $22 million and the acquisition of Sendai Publishing
Group for $28 million.
 
  For the year ended December 31, 1997, the Company generated $47.9 million in
cash from financing activities, principally $50.8 million of capital
contributed by MAC to fund the operating losses of the MAC Assets, net of a
$21.4 million repayment of intercompany indebtedness. Cash flow from financing
activity for the year 1996 was $6.8 million, primarily from capital
contributions of $14.8 million from Softbank offset by a dividend of $8.0
million.
 
  The Company believes that, based on its current level of operations and
anticipated growth, the Company's ability to generate cash, together with
other available sources of funds including available cash on hand at December
31, 1997, of $30.3 million, will be adequate over the next 12 months to make
required payments of principal and interest on the Company's indebtedness, to
fund anticipated capital expenditures and future working capital requirements.
However, actual capital requirements may change, particularly as a result of
any acquisitions the Company may pursue. The ability of the Company to meet
its debt service obligations and reduce its total debt will depend upon the
future performance of the Company.
 
  The Company has entered into a license and services agreement with MAC to
develop ZDTV. ZDTV is owned by MAC, but as part of this license and services
agreement MAC has granted the Company an option exercisable through December
31, 1998 to purchase all of MAC's interest in ZDTV for an amount equal to
 
                                      36
<PAGE>
 
   
MAC's investment plus 10% per annum for the period of its investment. Pursuant
to the license and services agreement, the Company has agreed to fund ZDTV's
operations on behalf of MAC through unsecured advances which, for approved
levels of expenditure, are to be reimbursed by MAC. Such advances bear
interest at the 30-day LIBOR rate plus .50%. ZDTV's cash requirements are
expected to be approximately $54 million in 1998. The Company's cumulative
advances in respect of ZDTV, which totaled $14.4 million net of $10.1 million
in repayments through December 31, 1997, will be repaid concurrently with the
Reorganization. The Company has not yet determined whether it will exercise
its option to purchase MAC's interest in ZDTV. Any such purchase will depend
upon securing sufficient cable carriage, which may include entering into a
joint venture or other co-ownership arrangement, including an arrangement with
a third party cable system operator which will provide carriage and also
assume a portion of the ongoing cash requirements on terms that are acceptable
to the Company. ZDTV is not included in the Company's results of operations.
In the event that the Company acquires a controlling interest in ZDTV from
MAC, such acquisition would be accounted for as a pooling transaction; in the
event that the Company acquires a non-controlling interest, such acquisition
would be accounted for under the equity method. See "Certain Transactions."
    
SEASONALITY
 
  Historically, the Company's business has been seasonal as a significant
portion of the trade shows and conferences segment revenue has occurred in the
second and fourth quarters. In addition, the Company's publishing segment has
generated higher revenue in the second and fourth quarters. The following
table sets forth certain unaudited quarterly combined statements of operations
data for each of the eight quarters in the period ended December 31, 1997. In
the opinion of the Company's management, this unaudited information has been
prepared on a basis consistent with the audited Combined Financial Statements
of ZDI and ZDCF appearing elsewhere in this Prospectus (with the exception of
the March 31, 1996 data which has been prepared on the basis described in
Presentation of Financial Information above) and includes all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the information set forth therein when read in conjunction with the Combined
Financial Statements and related notes thereto. The operating results for any
quarter are not necessarily indicative of results for any future period.

INFLATION AND CHANGES IN PAPER PRICES
 
  The Company continually assesses the impact of inflation and changes in
paper prices. The Company generally enters into contracts for the purchase of
paper which adjust the price on a quarterly basis. Paper prices began to rise
in 1994, rose significantly in 1995 and 1996 then decreased in 1997.
Management expects paper prices to increase again in 1998. The Company will
continue to monitor the impact of inflation and paper prices and will consider
these matters in setting its pricing policies.
 
  The Company frequently reviews its purchasing and manufacturing processes
for opportunities to reduce costs and mitigate the impact of paper price and
postage rate increases (such as purchasing lighter-grade paper stock or, when
paper prices are at cyclical lows, increasing paper inventory or entering into
longer term contracts
 
                                      37

with suppliers). However, the Company has not entered, and does not currently
plan to enter, into long-term forward price or option contracts for paper. See
"Risk Factors--Risks Associated with Fluctuations in Paper and Postage Costs"
and "Business--Print Publishing--Paper and Printing."
 
YEAR 2000 ISSUES
 
  The Company uses a number of computer software programs and operating
systems, including applications for its internal electronic communications
network and for various administrative and billing functions. The Company has
assessed the scope of the Company's risks related to problems these computer
systems may have in processing date information related to the year 2000 and
believes such risks are not significant.
 
  The Company has identified all of its significant internal software
applications which contain source codes that may be unable to appropriately
interpret the year 2000 and has already begun to modify or replace those
applications. The estimated costs to modify or replace these applications are
not material to the Company.
 
  In addition, the Company has inquired of its vendors and business partners
about their progress in identifying and addressing problems related to the
year 2000. All major vendors with whom the Company exchanges electronic
information or on whose internal software applications the Company may be
dependent, have committed to the Company that plans are in place to be
compliant before processing of information related to calendar year 2000 would
be required. Although no assurance can be given that all of these third party
systems will be year 2000 compliant, the Company believes that risk is not
significant.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  SFAS No. 130, "Reporting Comprehensive Income," issued in June 1997, will
require the Company to disclose, in financial statement format, all non-owner
changes in equity. Such changes include, for example, cumulative foreign
currency translation adjustments, certain minimum pension liabilities and
unrealized gains and losses on securities available for sale. This statement
is effective for fiscal years beginning after December 15, 1997 and requires
presentation of prior period financial statements for comparability purposes.
 
  SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," issued in June 1997, establishes standards for reporting
information about operating segments in annual financial statements and
interim financial reports. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
Generally, financial information is required to be reported on the basis that
is used internally for evaluating segment performance and deciding how to
allocate resources to segments.
 
  SFAS No. 132, "Employer's Disclosure about Pensions and Other Postretirement
Benefits," is effective for the year ended December 31, 1998. This statement
revises the disclosure requirements for employers' pension and other retiree
benefits.
 
  The Company expects to adopt the above statements beginning with its 1998
financial statements.
 
FORWARD-LOOKING STATEMENTS
 
  "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and other sections of this Prospectus contain forward-looking
statements which are subject to various risks and uncertainties. Actual
results could differ materially from those discussed herein. Important factors
that could cause or contribute to such differences include those discussed

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

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

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

PRINT PUBLISHING
 
  The Company is a leading computer-related magazine publisher, with 28
primary U.S. and international titles, including its joint ventures, and over
50 licensed publications, totaling more than 80 publications distributed
worldwide. In 1997, the Company's publications had combined circulation of
over eight million primary readers worldwide. Approximately 62% of the
Company's total revenue in 1997 was attributable to its print publishing
business. Each of the Company's magazines is designed to appeal to a target
audience of sophisticated customers in the business and consumer markets by
providing high-quality editorial content, often supported by independent
laboratory-based product testing. The Company seeks to maintain and increase
its revenue by introducing current advertisers to new titles, by attracting
new advertisers targeted at the Company's readership and by developing new
reader and advertising categories. Each of the Company's primary publications
has established its own Web site as a complementary delivery platform.
 
  The Company believes its preeminent position in the computer publishing
market is based upon its leading brands in key categories, its ability to
successfully develop new brands for emerging product categories, its strength
in circulation and its ability to expand internationally. Ziff-Davis seeks to
produce the highest quality editorial content; it employs top editors and
columnists supported by laboratory-testing facilities that produce widely
acknowledged authoritative benchmarks for determining product quality. See "--
Editorial, Laboratory Testing and Benchmark Software." In addition to its
leading publications targeted at brand-specifiers and other industry
professionals, the Company has successfully introduced new publications
targeted at emerging sectors, including the consumer market (Family PC,
Computer Life and Computer Gaming World), technology lifestyle (Yahoo!
Internet Life) and Internet professionals (Internet Computing and Inter@ctive
Week). The Company's newsstand strategy focuses on developing strong
relationships with a key distributor and large retail accounts. In order to
offer clients coverage of broad international markets, the Company has adopted
a licensing strategy designed to maximize global reach and maintain content
quality in international publications while reducing cost of entry into new
markets. Depending on the characteristics of a particular market, the Company
may choose to own an international publication, enter into a master license
covering one or more titles, or enter into a joint venture if an attractive
local partner can be identified.
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the
top three computer magazines in the U.S. and are among the top 25 U.S.
magazines, each as measured by total revenue in 1996 (the latest year for
which data is available). In 1997, Ziff-Davis was the largest technology
publisher in the U.S. in terms of total magazine revenue. In that same year,
Ziff-Davis accounted for 36.8% of all advertising and circulation dollars
spent in computer periodicals, with at least 50% more total magazine revenue
than its closest competitor. In recent years, advertisements in the Company's
publications have expanded beyond those for computer technology products to
include consumer product advertising, reflecting the desirable demographics of
the Company's readership, as well as the expanding readership of computer
technology publications to a broader consumer market.
 
  The Company's publications include paid-circulation magazines, which
generate revenue from newsstand sales, subscriptions and advertising, and
controlled-circulation publications, which are distributed free of charge to
qualified information technology professionals and generate revenue
principally from the sale of advertising. In addition, the readership of
controlled-circulation publications provides valuable demographic information
to the Company. Most of the current Ziff-Davis publications are either monthly
magazines providing comparative, laboratory-based product reviews or news
weeklies providing product and industry news and analysis; however, the
Company also serves the developing market for lifestyle and entertainment
publications focusing on technology.
   
  The Company's U.S. publications have a total circulation of over six million
primary readers, and the Company had a worldwide circulation of over eight
million primary readers. Its six paid-circulation business magazines
(including one joint venture) accounted for 47.2% of the total paid-
circulation of all computer technology business magazines in the U.S. in 1997.
In 1997, PC Magazine's circulation was greater than that of Business Week,
Fortune or Forbes. With respect to newsstand sales, a critical measure of
magazine vitality, in the first six months of 1997 Ziff-Davis accounted for
47.5% of all computer magazine copies sold, and on average Computer Shopper
had greater newsstand sales than Business Week, Fortune and Forbes combined.

 ZIFF-DAVIS MEDIA NETWORK
 
  The Company's Ziff-Davis Media Network integrates the Company's marketing
activities into one cohesive resource for its largest customers. Originally
established to provide discounts for advertisers buying across two or more
magazine titles, the Media Network has been expanded to allow marketers to
reach their various target buyers through any combination of the Company's
media and marketing platforms. Currently 21 professionals in the Ziff-Davis
Media Network link major advertisers from one platform into other platforms.
 
 EDITORIAL, LABORATORY TESTING AND BENCHMARK SOFTWARE
 
  The Company has invested heavily in its editorial staff and in training and
technology to develop the high level of technical expertise required to
provide quality content on computer technology. It employs over 450 editorial
personnel worldwide, including award-winning editors and experts in their
fields. The Company believes that it provides its consumers with the most
reliable, objective and focused product evaluations and industry news. Because
of the quality and reputation of Ziff-Davis laboratory tests, the Company's
publications are widely regarded as a reliable source of objective product
evaluations. The Company's influence over computer purchasing carries with it
the responsibility to maintain the highest standards of fairness and
objectivity in its product reviews. To ensure this impartiality, Ziff-Davis
has instituted policies governing separation of editorial functions from
advertising sales functions and restricting trading in securities of
technology-related companies by its journalists.
 
  The Company is committed to laboratory-based product testing as an integral
part of its editorial mission. In 1997, the Company spent over $10 million in
laboratory testing. Testers from many of the Company's different publications
work with the ZD Labs staff to provide comprehensive, objective test results
that can assist readers and users of Ziff-Davis publications and other
content-based services in making buying decisions. In addition to the core ZD
Labs staff, Ziff-Davis publications such as PC Magazine, PC Week, Computer
Shopper and PC Computing maintain their own staff and/or testing space at ZD
Labs as well as at their own locations. The ZD Labs testing facility provides
space for testing hundreds of products and systems. One of its newest
facilities is an Internet/Intranet lab dedicated to testing Web servers and
other Internet products. In its domestic lab facilities, the Company employs
120 technicians, enabling it to test thousands of products each year and
conduct large-scale tests that effectively simulate corporate installations.
The Company believes ZD Labs gives it a competitive advantage in terms of
staffing, equipment and access to the technology necessary to evaluate
products.
 
  ZD Labs produces the core, publicly available and widely distributed
benchmark software that Ziff-Davis publications use worldwide to measure the
performance of PCs, Macintosh systems and servers. The Company's benchmarks
have become industry standards among major buyers of computer and Internet-
related technology.
 
 SOURCES OF PRINT PUBLISHING REVENUE
 
  Advertising Sales. The Company's advertising strategy for its publishing
business is based on helping customers maximize the return on their
advertising investment. Advertising sales accounted for 78.4% of the Company's
total print publishing revenue for 1997. Ziff-Davis has historically invested
in comprehensive research to better understand the computer technology market
and the positions of its different publications. The Ziff-Davis sales
philosophy is to encourage its sales force to adopt the role of marketing
consultant, using Ziff-Davis market research tools, such as the Company's
InternetTrack and BrandTrack services, to provide clients with information on
overall industry trends as opposed to more limited sales presentations
focusing on individual publications. As of December 31, 1997, Ziff-Davis
employed over 250 salespeople, sales managers and sales executives and over
325 sales support staff in its publishing segment to provide customer service,
research, promotional support and value-added programs for advertisers.
 
  Circulation. Ziff-Davis maintains centralized circulation operations which
enable the Company to capitalize on its successful strategies and practices
across all publications on a timely basis. The Company strives
 
                                      45
<PAGE>
 
to increase its readership by building relationships with distributors,
retailers and subscribers. Revenue from circulation of the Company's paid-
circulation magazines accounted for 18.4% of the Company's total print
publishing revenue in 1997. This was comprised of subscription sales (10.1% of
total revenue in 1997 and 10.5% in 1996) and newsstand sales (8.1% in each of
1997 and 1996). The Company's publications have a total circulation of over
eight million primary readers worldwide.
 
  The Company's newsstand strategy focuses on developing strong relationships
with a key distributor and large retail accounts. Ziff-Davis recently entered
into a newsstand distribution arrangement in the U.S. with Warner Publishers
Services ("Warner"), a division of Time Warner Inc., which covers the
Company's entire line of paid-circulation magazines. As of January 1998, the
Company became Warner's principal supplier of computer technology
publications. In addition, the Company has preferred distribution arrangements
with large retailers including WalMart, Barnes & Noble, Staples and Office
Max. These arrangements include special magazine displays featuring Ziff-Davis
brand products which increase the prominence of the Company's publications and
strengthen its brand identity. With respect to newsstand sales, a critical
measure of magazine vitality, Ziff-Davis publications accounted for 47.5% of
all computer magazine copies sold in the first six months of 1997.
 
  The Company's subscription strategy is to maintain a highly focused
readership in order to provide the most effective affinity between advertisers
and readers. The Company believes that this strategy increases subscriber
loyalty and renewal rates and allows the Company to provide advertisers with
access to a precisely focused target audience. The Company's six paid-
circulation business magazines (including one joint venture) accounted for
47.2% of the total paid circulation of all computer technology business
magazines in the U.S. in 1996.
 
  Licensing and Joint Ventures. The Company has adopted a licensing strategy
designed to maximize global reach and maintain content quality in
international publications while reducing the cost of entry into new markets.
In markets where the Company believes that the opportunity is significant
relative to the cost of entry, the Company may operate through wholly-owned
publishing companies. Through subsidiaries, the Company currently has
publishing operations in France, the United Kingdom and Germany. In other
markets, the Company has opted to enter into licensing arrangements with local
publishing companies, and currently has over 50 licensed publications
worldwide. The Company's licenses are generally three to five year agreements
that provide for a minimum annual royalty against a percentage of revenue. The
Company also operates through a number of joint venture companies with
partners, including joint ventures with International Data Group, Inc. ("IDG")
and an affiliate of The Walt Disney Company ("Disney") in the U.S. and a
venture with Richina Media Holdings and other local agencies in China. The
Company is currently negotiating with an affiliate of Disney to buy its
interest in the Family PC joint venture.
 
 U.S. PUBLICATIONS
 
  Business Magazines. In the U.S. market, the Company publishes ten computer
publications directed to business buyers, including six paid-circulation
magazines and four controlled-circulation weeklies or bi-weeklies. Each

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

TRADE SHOWS AND CONFERENCES
 
  The Company is the leading producer of trade shows, conferences and
customized marketing and educational programs for the computer industry in the
U.S. Approximately 25% of the Company's total revenue in 1997 was attributable
to its trade show and conference business which includes the industry-wide
COMDEX events, other trade shows and conferences focused on specific segments
of the computer technology industry, and customized events designed to meet
the marketing needs of specific clients. In 1997, the Company produced over 50
trade shows and conferences, 18 of which were held in North America.
 
  The COMDEX/Fall event has been held for 18 years and is the number one
ranked trade show for all industries in the U.S. as measured by total revenue,
total exhibit space and number of attendees. In 1997, the Company estimates
that over two million people attended Company trade shows and conferences
worldwide. In addition to COMDEX/Fall, held annually in Las Vegas, the Company
produces 18 other COMDEX events in 13 countries.
 
  "NetWorld+Interop" ("N+I") and "Seybold Seminars" are segment-focused
Company trade shows. In 1997, nine such shows were held in six countries. The
N+I trade shows focus on the networking/interconnectivity segment of the

Microsystems, Inc. which were designed to introduce Java software to the
developer community.
 
  Attendees at the Company's trade shows and conferences cover a wide range of
participants from the computer industry, including manufacturers,
distributors, dealers, retailers, value-added and other resellers and large
corporate end-users. Each event includes an extensive conference program,
which provides a forum for the exchange and dissemination of information
germane to the particular event's focus. In addition, each event has one or
more "keynote" sessions with speakers drawn from computer industry leaders.

exhibitors in its trade shows and conferences and over 8,000 industry experts,
analysts and consultants spoke at its conference programs.

 SOURCES OF TRADE SHOW AND CONFERENCE REVENUE
 
  In 1997, exhibitor space fees accounted for 64.8% of the Company's total
trade show and conference revenue. The Company believes most trade show
producers receive virtually all of their revenue from the sale of exhibitor
space fees. The Company has actively sought to increase its revenue from other
sources, including attendee fees, which accounted for 35.2% of all trade show
and conference revenue in 1997.
 
  At each trade show, all exhibitors pay the same price per square foot of
booth space, regardless of the exhibit hall they select or the location or
size of their booth within a given hall. Typically, a majority of each trade
show's exhibitors commit to booth space during that year's show for the next
year's show. The Company encourages this commitment through a booth selection
procedure that grants priority based upon a seniority system. Annual renewal
is required for exhibitors to maintain their seniority. Exhibitors pay for
space in two or three installments, the last of which is usually due six
months prior to the upcoming event.
 
  In 1997, attendee fees accounted for 14.9% of the Company's trade show and
conference revenue, primarily from N+I and Seybold events. Most COMDEX
attendees come as the invited guests of exhibiting companies. The Company
provides exhibiting companies with a supply of complimentary admission
tickets, which are generally given to customers and key prospects. This helps
exhibitors ensure that their best customers and prospects will attend.
 
  The Company's trade show and conference advertising revenue is derived
principally from five products: (i) a daily newspaper distributed during the
show; (ii) the Program Exhibits Guide; (iii) the Preview, a newspaper
published and distributed to pre-registrants and certain prior year attendees
in advance of the show; (iv) advertising billboards and banners; and (v)
ancillary exhibitor logo products which are sold to exhibitors to increase
booth traffic and name recognition.
 
  The Company also maintains a continuously updated database containing the
names and certain demographic information on its over two million attendees.
This database is rented to direct mail users on a fee-per-use basis.
 
 COMDEX
 
  COMDEX trade shows cover a broad range of new technologies at every stage in
their development and evolution--from introduction to commercial maturity.
Many of the most significant computer product launches over the past 18 years
occurred at COMDEX, including the launch of the IBM PC, Lotus 1-2-3, Windows
3.1 and DVD.
 
  COMDEX/Fall is a five-day trade show held annually in November in Las Vegas.
In 1997 COMDEX/Fall had over 1,750 exhibiting companies occupying more than
1,350,000 net square feet of exhibit space and more than 200,000 attendees.
COMDEX/Spring, which was launched in 1981, is a smaller version of the fall
event. In 1997, it was held in Atlanta and had more than 600 exhibiting
companies and over 100,000 attendees. In April 1998, COMDEX/Spring will be
held in Chicago. For the last six years, the Company, in cooperation with
Microsoft Corporation, has produced a WINDOWS WORLD trade show concurrently
with COMDEX/Spring.
 
  In 1993, the Company began launching additional COMDEX events in order to
capitalize on the international recognition of the COMDEX brand name. The 1998
schedule includes other COMDEX events in Miami, Toronto, Vancouver, Montreal,
Mexico City, Monterrey (Mexico), Buenos Aires, Sao Paulo, Rio de Janeiro,
London, Paris, Tokyo, Seoul, New Delhi, Beijing, Singapore and Cairo.
 
 NETWORLD + INTEROP
 
  N+I is the largest of the Company's segment-focused trade shows and is the
leading show for professionals in the rapidly growing field of computer
networking. N+I places strong emphasis on the quality of its conference
programs and, in recent years, has become a leading educational forum for the
Internet and enterprise computing
 
                                      51
<PAGE>
 
communities. The largest N+I event is held annually in Las Vegas in May. Each
N+I trade show features InteropNet, a live, multi-platform network that
interconnects exhibitors to one another and to the Internet. In 1997, the N+I
Las Vegas event had over 600 exhibiting companies occupying more than 400,000
net square feet of exhibit space and more than 55,000 attendees. The N+I
Atlanta event, held in October each year, is only slightly smaller in all
categories. The 1998 schedule of N+I events includes seven shows in six
countries.
 
 SEYBOLD SEMINARS
 
  The Company's Seybold Seminars are segment-focused trade shows and are a
leading information and education provider for traditional and new media
publishing industries. These shows focus on the latest technologies and
products, design tools and desktop applications. The largest of the Seybold
series is held annually each September in San Francisco. In 1997, this Seybold
show had over 300 exhibiting companies occupying more than 140,000 net square
feet of exhibit space and more than 38,000 attendees. Other Seybold events are
held in New York and Tokyo.
 
 OTHER EVENTS
 
  The Company also produces EXPO COMM, a series of worldwide trade shows
focusing on the telecommunications, wireless and telephony segments of the
information technology marketplace. The Company purchased a 50% interest in
the series from EXPO COMM's founder, E.J. Krause & Associates, Inc., in 1996.
EXPO COMM events are held in Chicago, Moscow, Beijing, Buenos Aires, Sao
Paulo, Mexico City, Monterrey (Mexico) and Tokyo. WINDOWS WORLD trade shows
are held in cooperation with Microsoft Corporation concurrently with the
Company's COMDEX events in Chicago, Mexico City and Toronto. These events
showcase the latest Windows-based applications and solutions.
 
  The Company also produces Learning Technology trade shows for professionals
focused on learning and helping others to learn to use technology, held in
Atlanta and Los Angeles, and Object World trade shows focused on the
commercial and practical aspects of applying object technology and distributed
computing in today's business environment, held in San Francisco, Boston,
London, Frankfurt and Tokyo.
 
INTERNET
 
  The Company maintains a number of Web sites related to its publications,
trade shows and conferences and other media platforms. The Company's ZDNet.com
Web site is the leading computing content site and the number one Web site in
the category of news, information and entertainment, in each case as measured
by visitors per month in 1997, ranking it higher than Web sites produced by
Time Warner Inc. (Pathfinder.com), Disney (Disney.com) and ESPN
(Sportzone.com). The Company estimates that the ZDNet Web site serves more
than 100 million pages each month to more than five million visitors. It has
over one million registered users and over 2.5 million e-mail recipients per
month. ZDNet has successfully attracted new audiences in addition to
established computer enthusiasts, as is evidenced by the fact that 64% of
ZDNet users do not regularly read any computer technology publications. ZDNet
seeks to be the most comprehensive site for quality content about computing.
 
  ZDNet has its own staff of over 100 editors, designers and technology
experts who create and develop a wide range of content, including current and
in-depth news, product reviews, investor information, shareware library,
online shopping, training, forums and chat areas. ZDNet coordinates and
collaborates on content development with the Company's other publications and
businesses and is fully integrated with the Company's individual Web sites.
ZDNet includes Netbuyer, a leading Web site devoted to computer retailing.
Softbank is a majority owner of Gamespot, a leading Web site for gaming
information, including reviews, demo downloads and other content. Softbank's
interest in Gamespot will be contributed to the Company concurrently with the
Reorganization. Over 80% of the content on ZDNet is original, with the
remainder supplied by the Company's print publications.
 
                                      52
<PAGE>
 
  The Company has a number of arrangements with leading Web sites and product
manufacturers to increase traffic and thereby advertising revenue to ZDNet.
ZDNet is the preferred computer and technology content-provider for leading
Internet sites and products, including Yahoo!, Excite, MSNBC and Pointcast, as
well as for leading Internet service providers such as Mindspring and AT&T's
World Net, each of which provides a direct link to ZDNet. ZDNet also has
arrangements with original equipment manufacturers, such as Compaq Computer
Corp. and Gateway 2000, Inc., whereby ZDNet is an automatic bookmark in the
Web browsers included on such computers.
 
  The Company distributes localized versions of ZDNet in Germany as ZDNet
Deutschland, in France as ZDNet France and in the United Kingdom as ZDNet UK.
Localized versions of ZDNet are also distributed by licensees in Italy,
Russia, Japan, China, Taiwan, Australia and Latin America.
 
TELEVISION
 
  In order to expand its media platforms, the Company has entered into a
license and services agreement with MAC to develop ZDTV, which is expected to
be launched in the first half of 1998. ZDTV will be the first 24-hour cable
television channel and integrated Web site focused exclusively on computers,
technology and the Internet. ZDTV will target a wide range of viewers,
including computer and technology enthusiasts, computer gaming enthusiasts,
business people, teens, families and other viewers with a sustained interest
in computers, technology and the Internet. Programs are expected to include
educational features, product evaluations, gaming tips and strategies, current
events and other entertainment. ZDTV will also feature live interactive
programming allowing viewers to participate through simultaneous Web
programming on ZDTV.com.
 
  ZDTV is owned by MAC, but as part of the license and services agreement, MAC
has granted the Company an option exercisable through December 31, 1998 to
purchase all of MAC's interest in ZDTV for an amount equal to MAC's investment
plus 10.0% per annum for the period of its investment. The Company is
currently funding ZDTV's operations on behalf of MAC through unsecured
advances which, for approved levels of expenditure, are to be reimbursed by
MAC. Such advances bear interest at the 30-day LIBOR rate plus .50%. ZDTV's
cash requirements are expected to be approximately $54 million in 1998. The
Company's cumulative advances in respect of ZDTV, which totaled approximately
$14.4 million net of $10.1 million in repayments through December 31, 1997,
will be repaid concurrently with the Reorganization. The Company has not yet
determined whether it will exercise its option to purchase MAC's interest in
ZDTV. Any such purchase will depend upon access to sufficient cable carriage,
which may include entering into a joint venture or other co-ownership
arrangement, including an arrangement with a third party cable system operator
which will provide carriage and also assume a portion of the ongoing cash
requirements on terms that are acceptable to the Company. ZDTV is not included
in the Company's results of operations. See "Certain Transactions."
 
  ZD Television Productions, which is also owned by MAC, creates customized
programming for ZDTV and third parties. The Company's option to purchase ZDTV
from MAC also includes the option to purchase ZD Television Productions. Its
productions have included the regional Emmy award-winning "The Site" with
MSNBC and "21st Century Home" with Home & Garden Television. See "Certain
Transactions."
 
EDUCATION
 
  The Company is an independent publisher of computer training products and
services for end-users and advanced technology professionals. Its products and
services include Internet-based training, computer-based training, instructor-
led courseware and customization tools. The Company believes that its
education offerings extend the Company's reach and brand reputation while
permitting the Company to attract and retain customers.
 
  The Company is a source of software-specific newsletters and technology
information, with more than 50 titles, a family of CD-ROM products and an
interactive Web site. Generally published monthly, the titles include time-
saving tips and techniques on products such as Windows 95, Novel NetWare,
Visual Basic, Word, Excel, Microsoft Office, PhotoShop and Windows NT, in
addition to several programming and operating systems journals. The Company's
informational Web site provides instant access to a library of back issues,
reviews, online links and chats with authors.
 
                                      53
<PAGE>
 
  Through ZD University, an Internet-based educational program, the Company
provided training to more than 37,000 paid subscribers in 1997, an increase of
100% from 1996. The ZD University Web site is closely integrated with ZDNet,
helping to ensure that customers of one service are exposed to other Company
services.
 
  Through the Help Desk Institute and the Support Services Professionals
Association, the Company provides training programs and publications for
hardware and software support service professionals. The Company also
publishes Inside Technology Training, which reaches 40,000 information
technology and training managers, and other software support professionals. In
addition, the Company owns and operates a single-site training center that
specializes in applications, programming and certification training for
Microsoft, Novell and Lotus, and the Training Center Alliance, which provides
qualifying training center customers with enhanced marketing support and
referral capabilities worldwide.
 
MARKET RESEARCH
 
  The Company's market research division develops, analyzes and compiles a
wide variety of information on computer technology issues ranging from
technical aspects of current usage to trends in decision making. The Computer
Intelligence ("CI") unit focuses on information concerning installed and
planned technology hardware and software purchases, and is a leading source in
North America and Europe of fact-based information concerning hardware and
software needs for the computer and communications industries. CI is an
important part of the Company's effort to be a single source marketing
solution, as it can provide the Company's marketing customers with important
information to identify their target customers. CI's databases are built from
more than 30,000 telephone interviews per month and contain data on installed
and planned computer and communications products and services at over 400,000
business sites in the U.S., Canada and eight European countries, according to
Company estimates. CI assists the Company's clients in identifying and
targeting their customers by tracking current activity and market share in the
business, home and reseller channels. Customers use CI's services to make
important marketing decisions.
 
  The Company also identifies and analyzes trends in the decision making
process for consumers of computer technology. This type of information helps
to identify criteria other than technical product specifications that are used
in product selection. The Company's market research division also consolidates
information obtained in each of the databases maintained by the Company's
other operating divisions, so that each Ziff-Davis division can offer the
Company's clients a wide range of information to meet their marketing needs
across multiple platforms.
 
  The Company publishes Microprocessor Report, a leading technical publication
for the microprocessor industry. It also produces Microprocessor Forum, the
industry's leading conference for the introduction of new high-performance
microprocessors, and PC Tech Forum, events which together attract more than
1,000 paid attendees and provide information on trends and markets.
 
COMPETITION
 
  The Company competes with a wide range of companies for each of the products
and services it provides. Although such competition is significant and is
likely to increase in the future, the Company believes it has a greater
breadth of product and service offerings than any of its competitors.
 
  The magazine publishing business is highly competitive. The Company faces
broad competition, not only from other technology publishers, but from other
media companies as well, including business, news and general interest
magazine publishers. Other principal computer and technology publishers in the
United States include IDG, CMP Media Inc., The McGraw-Hill Companies and
Imagine Publishing, each of which produces publications that directly compete
with one or more of the Company's publications. The Company also competes with
various computer and technology publishers in the international markets in
which it conducts business. A
 
                                      54
<PAGE>
 
publishing company's success depends upon a number of factors, such as
editorial quality, product positioning and price. Competitive factors for
advertising sales include quality of readership, circulation, reader response
and advertising rates. The Company believes its publications effectively
compete in the marketplace on the basis of each of these factors.
 
  The Company also faces competition in its trade show and conference
business, primarily from several significant trade show management companies.
These include Miller Freeman, Mecklermedia Corporation and IDG. The Company
believes its trade shows compete in the marketplace on the basis of quality of
conference content, organizational efficiency, and quality and number of
exhibitors and attendees.
 
  The Internet media business is highly competitive. An increasing number of
companies are developing online content and services for delivery on the World
Wide Web in order to compete for audiences and the advertising dollars that
are currently being directed to the Internet. ZDNet competes with other
technology-related online content sites such as c|net, CMPnet, and IDGnet.
 
  The Company's market research division faces competition from numerous
market research companies, including International Data Corporation, Gartner
Group's Dataquest and IntelliQuest. Database providers such as Information
Resource Group and Dun & Bradstreet provide additional competition.
 
  The Company's education division competes with a variety of education
providers, including vendor-supplied training materials and traditional
classroom-based computer training.
 
  ZDTV is expected to be the first 24-hour cable television channel and
integrated Web site focused on computer technology and the Internet, and as
such it is not expected to face direct competition in the near future. It
will, however, face competition from a variety of general and special interest
television programs. The market for television programming is highly
competitive, with many programming producers competing both for channel
carriage and for advertiser and audience market share.
 
TRADEMARKS
 
  The Company has developed strong brand awareness for its principal
publications, trade shows and other products and services. Accordingly, the
Company considers its trademarks, copyrights, trade secrets and similar
intellectual property as critical to its success and relies on trademark,
copyright and trade secrets laws, as well as licensing and confidentiality
agreements, to protect its intellectual property rights. The Company generally
registers its material trademarks in the United States and in certain other
key countries in which these trademarks are used. Effective trademark,
copyright and trade secret protection may not be available in every country in
which the Company's publications and services are available.
 
  The Company may be subject to claims of alleged infringement by it or its
licensees of trademarks and other intellectual property rights of third
parties from time to time in the ordinary course of business. The Company does
not believe there are any such legal proceedings or claims that are likely to
have, individually or in the aggregate, a material adverse effect on the
Company's business, financial condition or results of operations.
 
FACILITIES
 
  The Company's world headquarters are located in New York and the Company has
over 50 editorial, production and sales offices and computer labs in many
other cities in the United States and around the world. The Company's other
principal offices are located in the Boston and San Francisco metropolitan
areas. The Company does not own real property that is material to its business
and leases all but one of its offices from third parties. The Company believes
that its properties, taken as a whole, are in good operating condition and are
suitable and adequate for the Company's current business operations, and that
suitable additional or alternative space, including space available under
lease options, will be available at commercially reasonable terms for future
expansion.

BOARD COMPOSITION
   
  Following the Offering, the Board of Directors will consist of ten members,
which will include the nine current members of the Board plus one additional
"independent director" (within the meaning of the regulations of the New York
Stock Exchange (the "NYSE")) nominated for election by the Board of Directors.
It is expected that the new director will be elected by the Board within three
months following the closing of the Offering. Directors of the Company are
currently elected annually by its stockholders to serve during the ensuing
year or until their respective successors are duly elected and qualified.
Following the Offering, the Board of Directors will be divided into three
classes each of whose members will serve for a staggered three-year term. Upon
the expiration of the term of a class of directors, directors in such class
will be elected for three-year terms at the annual meeting of stockholders in
the year in which such term expires. See "Description of Capital Stock--
Certain Provisions of the Certificate of Incorporation and By-laws."     
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
  The Board of Directors currently has two committees: an Audit Committee and
a Compensation Committee.
 
  The Audit Committee will be comprised of the independent directors. The
Audit Committee reviews and recommends to the Board, as it deems necessary,
the internal accounting and financial controls for the Company and the
accounting principles and auditing practices and procedures to be employed in
preparation and review of financial statements of the Company. The Audit
Committee makes recommendations to the Board concerning the engagement of
independent public accountants and the scope of the audit to be undertaken by
such accountants. Price Waterhouse LLP presently serves as the independent
accountants of the Company.
   
  The Compensation Committee is currently comprised of Mr. Fisher, who,
following the Offering, will be joined by the two independent directors. The
Committee reviews and, as it deems appropriate, recommends to the Board
policies, practices and procedures relating to the compensation of the
officers and other managerial employees and the establishment and
administration of employee benefit plans. The Committee exercises all
authority under any employee stock option plans of the Company as the
Committee therein specifies (unless the Board resolution appoints any other
committee to exercise such authority), and advises and consults with the
officers of the Company as may be requested regarding managerial personnel
policies. The Committee will have such additional powers and be granted
additional authority as may be conferred upon it from time to time by the
Board.     
 
COMPENSATION OF DIRECTORS
 
  Directors who are not executive officers or employees of the Company or
Softbank will receive an annual retainer of $25,000 for Board of Directors
service and a fee of $2,000 for each meeting of the Board of Directors or any
committee thereof attended.
 
  The Company has adopted the 1998 ZD Inc. Incentive Compensation Plan (the
"1998 Incentive Compensation Plan"). Directors of the Company who are not
employees of the Company or any of its subsidiaries ("Non-employee Directors")
will automatically participate in the 1998 Incentive Compensation Plan. See
"--Stock Plans--Incentive Compensation Plan" for a detailed discussion of the
1998 Incentive Compensation Plan.
 
 
                                      59
<PAGE>
 
   
  Pursuant to the 1998 Incentive Compensation Plan, each Non-employee Director
shall receive upon election as a member of the Board an initial grant of stock
options to purchase 10,000 shares of Common Stock; provided, that each Non-
employee Director who is on the Board of Directors on the date of the Offering
shall receive such initial grant of stock options on the date of the Offering.
Each Non-employee Director shall automatically receive on each annual meeting
thereafter an annual grant of stock options to purchase 7,500 additional
shares of Common Stock. The terms of each stock option granted to a Non-
employee Director shall provide that (i) the option price shall be equal to
100% of the fair market value (as defined in the 1998 Incentive Compensation
Plan) of the Common Stock on the date of grant, (ii) such option shall be
exercisable for a period of ten years following the date of grant, and (iii)
such option shall vest and become exercisable in five equal installments
beginning on the first anniversary of the date of grant.     
 
  Upon ceasing to be a Non-employee Director, such option shall terminate
except with respect to any portion of such option then exercisable, which
portion shall remain exercisable for a period of (x) 90 days, if the
termination as Director resulted from any reason other than death, disability
or Cause (as defined in the 1998 Incentive Compensation Plan), or (y) one
year, if the termination resulted from death or disability; provided, that in
the event the termination resulted from a removal for Cause, such option shall
immediately terminate and no longer be exercisable to any extent; provided,
further, that in no event shall any such option remain exercisable past the
remainder of its scheduled ten-year term.
 
  Upon a "change in control" of the Company (as defined in the 1998 Incentive
Compensation Plan), each outstanding option shall fully vest and become
immediately exercisable in full. In addition, the Committee may provide in its
sole discretion that upon a change in control of the Company, each Non-
employee Director shall be entitled to receive in cancellation of such Non-
employee Director's outstanding and unexercised stock options, a cash payment
in an amount equal to the difference between the option price of such stock
options and (i) in the event the change of control is the result of a tender
offer or exchange offer for the Common Stock, the final offer price per share
paid for the Common Stock, multiplied by the number of shares of Common Stock
covered by such stock options, or (ii) in the event the change of control is
the result of any other occurrence, the aggregate value of the Common Stock
covered by such stock options, as determined by the Committee at such time.

STOCK PLANS
 
 Incentive Compensation Plan
 
  General.  The Company has adopted a 1998 Incentive Compensation Plan (the
"Plan") to provide long-term incentives for its key employees and enhance
shareholder value. The Plan will be administered by the Compensation Committee
(for purposes herein, the "Committee"), which will (i) select the
participants, determine the type of awards, and the number of shares or share
units subject to awards, and (ii) interpret the Plan and make all other
determinations necessary or advisable for its administration.
 
  All employees and consultants of the Company and its affiliates who have
demonstrated significant management potential or the capacity for contributing
substantially to the successful performance of the Company and its affiliates,
are eligible to be participants in the Plan. Awards may consist of stock
awards, stock options (either incentive stock options within the meaning of
Section 422 of the Internal Revenue Code or nonstatutory stock options), stock
appreciation rights, performance shares (which may be granted as performance
share units) and restricted stock (which may be granted as restricted stock
units).
   
  The Common Stock available for awards under the Plan shall not exceed
8,500,000 shares. In the event of any change in the outstanding shares by
reason of any stock dividend or split, recapitalization, merger or other
corporate change, or any distributions to common shareholders other than
regular cash dividends, the Committee may make such substitution or
adjustment, if any, as it deems to be equitable, as to the number or kind of
shares of Common Stock or other securities issued pursuant to the Plan and to
outstanding awards. Shares subject to an award that expires unexercised, is
forfeited, or terminated, or settled in cash in lieu of Common Stock, and
shares tendered to pay for the exercise of a stock option, shall thereafter
again be available for grant under the Plan.     
 
  Each award under the Plan shall be evidenced by an agreement setting forth
the terms and conditions, as determined by the Committee, which apply to such
award. In the sole discretion of the Committee, a participant may be permitted
to defer the receipt of cash or Common Stock otherwise deliverable under any
award.
   
  Stock Options. The Committee shall establish the option price at the time
each stock option is granted, which price shall not be less than 100% of the
fair market value of the Common Stock on the date of grant. Stock options
shall vest and become exercisable at a rate determined by the Committee, and
shall remain exercisable for such period as specified by the Committee. The
award agreements in respect of options that are intended to qualify as
incentive stock options will contain any additional provisions necessary to
comply with the requirements of Section 422 of the Internal Revenue Code. In
no event may any employee receive in any calendar year grants of stock options
with respect to more than 1,000,000 shares of Common Stock.     
 
  The option price of each share as to which a stock option is exercised will
be paid in full at the time of such exercise in cash, by tender of shares of
Common Stock owned by the participant valued at fair market value, by a "sale
to cover" broker transaction or other cashless exercise method permitted under
Regulation T of the Federal Reserve Board, or by a combination of cash, shares
of Common Stock and other consideration as the Committee deems appropriate.
   
  Stock Appreciation Rights. Stock appreciation rights ("SARs") may be granted
in tandem with a stock option or unrelated to a stock option. SARs shall vest
and become exercisable at a rate determined by the Committee, and shall remain
exercisable for such period as specified by the Committee. A SAR entitles its
holder to receive from the Company an amount equal to the excess of the fair
market value of a share of Common Stock on the exercise of the SAR over the
fair market value on the date of grant. The Committee may determine in its
sole discretion whether a SAR will be settled in cash, Common Stock or a
combination thereof. In no event may any employee receive in any calendar year
grants of SARs with respect to more than 500,000 shares of Common Stock.     
 
  Performance Shares. Performance shares may be granted in the form of actual
shares of Common Stock or share units having a value equal to an identical
number of shares of Common Stock. The performance
 
                                      61
<PAGE>
 
conditions and the length of the performance period will be determined by the
Committee but in no event may a performance period be less than one year. The
Committee may determine in its sole discretion whether performance shares
granted in the form of share units shall be paid in cash, Common Stock, or a
combination thereof.
   
  Unless the Committee determines otherwise, awards of performance shares to a
Covered Employee will be subject to performance conditions based on the
achievement by the Company of target levels of items such as consolidated net
income, return on shareholders' equity, return on net assets or share price
performance. For purposes of the 1998 Incentive Compensation Plan, a "Covered
Employee" generally includes any employee that would be a covered employee
within the meaning of Section 162(m) of the Internal Revenue Code, and any
other employee of the Company or its subsidiaries designated by the Committee
in its discretion. The maximum number of performance shares subject to any
award to a Covered Employee is 500,000 for the first 12 months during the
performance period and each 12-month period thereafter.     
 
  Restricted Stock. Restricted stock may be granted in the form of actual
shares of Common Stock or share units having a value equal to an identical
number of shares of Common Stock. The employment conditions and the length of
the period for vesting of restricted stock will be established by the
Committee at time of grant, except that each restriction period shall not be
less than twelve months. During the restricted period, shares of restricted
stock may not be sold, assigned, transferred or otherwise disposed of, or
pledged or hypothecated as collateral for a loan or as security for the
performance of any obligation or for any other purpose as the Committee shall
determine. The Committee may determine in its sole discretion whether
restricted stock granted in the form of share units will be paid in cash,
Common Stock or a combination thereof.
 
  Stock awards. In addition to awards of performance shares and restricted
stock, awards of Common Stock may be granted under the Plan in the form of
actual shares of Common Stock. Full ownership of such shares, whether issued
in the form of a certificate or in book entry, including the right to vote and
receive dividends, shall immediately vest in such participant.
 
  Change in Control. In the event of a Change in Control (as defined below):
(i) all stock options will be fully vested and exercisable in full (ii) all
SARs which have not been granted in tandem with stock options will become
exercisable in full (iii) the restrictions applicable to all shares of
restricted stock will lapse and such shares will be deemed fully vested and
all restricted stock granted in the form of share units will be paid in cash;
(iv) all performance shares will be deemed to be earned at target level; and
(v) all performance shares granted in the form of share units will be paid in
cash.
 
  For purposes of the Plan, "Change in Control" is generally defined as (i) a
change in the majority of the Board except upon consent of the previous Board;
(ii) certain mergers, consolidations or similar corporate transactions in
which the Company is not the surviving corporation or entity; or (iii) the
shareholders of the Company approve a plan of complete liquidation or
dissolution of the Company or a sale of all or substantially all of the
Company's assets; provided, that a Change in Control will not be deemed to
occur under clause (ii) if Softbank, directly or indirectly, is the beneficial
owner of more than 25% of the Company's voting securities or of the voting
securities of any surviving corporation, respectively.
 
  Amendment and Termination. The Board may amend, suspend or terminate the
Plan or any portion thereof at any time, provided that (a) no amendment will
be made without stockholder approval (including an increase in the number of
shares reserved for issuance under the Plan) if such approval is necessary to
comply with any applicable law, regulations or stock exchange rule, and (b)
except as otherwise provided under the cashout provisions in the event of a
Change in Control, no amendment will be made that would adversely affect the
rights of a participant under any award previously granted, without such
participant's written consent.
 
                                      62
<PAGE>
 
  Effective Date. The Plan will have a term of ten years from February 15,
1998, subject to earlier termination.
 
 Softbank Executive Stock Option Plans
 
  The SOFTBANK Group Executive Stock Option Plans (the "Softbank Plans")
authorize the grant of options to those officers, directors and key employees
of Softbank as selected by a committee appointed by the Board of Directors of
SOFTBANK Holdings Inc. The Softbank Plans authorize the granting of options to
purchase SOFTBANK Corp. common stock at not less than 100% of the closing
market price on the date the option is granted. As of December 31, 1997,
substantially all options granted become exercisable in various installments
over the first six anniversaries of the date of grant and expire ten years
after the date of grant.
 
  As of December 31, 1997, 966,986 options had been granted under the Softbank
Plans. On January 23, 1998, the exercise price of all options was reset at
4,000 Japanese yen per share, the market price of SOFTBANK Corp.'s common
stock on that date.
 
 Employee Stock Purchase Plan
 
  General. The Company has adopted an employee stock purchase plan (the "Stock
Purchase Plan"). The Stock Purchase Plan is intended to meet the applicable
requirements of Section 423 of the Internal Revenue Code and will be
administered by the Committee.
   
  Option to Purchase. Under the Stock Purchase Plan, all full-time and certain
part-time employees of the Company who meet certain minimum service
requirements will be eligible to purchase shares of Common Stock by means of
payroll deductions, except for certain employees who earn above a certain
level of total compensation and participate in the 1998 Incentive Compensation
Plan. Eligible employees may elect to participate in offering periods by
authorizing after-tax payroll deductions of between 1% and 10% (in whole
percentages) of their base pay for the purchase of shares of Common Stock. The
aggregate maximum number of shares of Common Stock purchasable under the Stock
Purchase Plan is 1,500,000, subject to adjustment by the Committee in its sole
discretion in the event of any increase, reduction or change or exchange of
shares of Common Stock for a different number or kind of shares or other
securities of the Company by reason of any stock dividend or split,
recapitalization, merger, consolidation, spin-off, combination or exchange of
shares or other corporate change, or any distribution to common shareholders
other than cash dividends. Upon the dissolution or liquidation of the Company,
or upon a reorganization, merger or consolidation of the Company as a result
of which the Company is not the surviving corporation, or upon a sale of
substantially all of the Company's assets, or a sale or distribution of a
subsidiary of the Company, any affected participant will thereafter be
entitled to receive, for each share of Common Stock subject to such
participant's option, the cash, securities and/or property which a holder of
one share of Common Stock was entitled to receive upon and at the time of such
transaction.     
 
  The price at which shares of Common Stock will be purchased at the end of
each purchase period will be the lesser of (i) 85% of the Fair Market Value of
a share of Common Stock on the first business day of such purchase period or
(ii) 85% of the fair market value on the last business day of each purchase
period. No participating employee will be entitled in any calendar year to
purchase Common Stock having an aggregate fair market value as of the first
business day in any Purchase Period in excess of $25,000.
 
  Amendment and Termination. The Board may at any time terminate or amend the
Plan. No such termination shall adversely affect options previously granted
and no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. No amendment shall be
effective unless approved by the shareholders of the Company if such
shareholder approval of such amendment is required to comply with any law,
regulation or stock exchange rule.

                             CERTAIN TRANSACTIONS
 
ARRANGEMENTS BETWEEN THE PRINCIPAL STOCKHOLDERS AND THE COMPANY
 
  The Company and Softbank have entered into certain agreements governing
ongoing business relationships between them, including: (i) a master license
agreement for Softbank's producing and distributing Ziff-Davis publications in
Japan; (ii) a license agreement for Softbank's operating ZDNet in Japan; and
(iii) a series of agreements, including a service mark license agreement,
technical assistance agreement and accounting and administrative services
agreement, pursuant to which the Company will manage all ZDCF trade shows and
conferences conducted in Japan, but owned by Softbank. Total revenue earned by
the Company from such trade show and conference agreements will approximate
50% of the pre-tax income generated by such trade shows and conferences.
 
  Softbank has given the Company an undertaking not to expand operations
involving (x) publishing information on computing and Internet-related
technology through the media of print, CD-Rom/DVD, Internet and television, or
(y) producing trade shows, conferences, exhibitions and similar events
primarily related to computing and Internet-related technology outside Japan
in competition with the Company without the prior approval of the Company's
management directors after consulting with the Company's independent
directors. This undertaking does not preclude investments by investment funds
managed by Softbank. Softbank manages certain venture capital funds which
invest in, among other things, computer and Internet-related companies. These
funds may be able to co-invest with the Company or compete with the Company
with respect to new investments. Softbank may develop new funds in the future,
which funds may compete with the Company for investment opportunities. The
Company has undertaken not to compete with Softbank in Japan without the prior
approval of SOFTBANK Corp.'s Board of Directors and to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest."
   
  The Company and Softbank entered into a Registration Rights Agreement, dated
as of April 1, 1998, in connection with the Offering. The Agreement entitles
Softbank to require the Company to register any or all of the Common Stock
held by it in a public offering pursuant to the Securities Act of 1933, as
amended, as well as to "piggyback" or include its shares of Common Stock in
any registration of Common Stock made by the Company.     
 
CERTAIN RELATED PARTY TRANSACTIONS
 
  The Company is a member of a group of companies affiliated through common
ownership under SOFTBANK Corp. and has various transactions and relationships
with members of the group, including SOFTBANK Corp.'s wholly-owned U.S.
subsidiary, SOFTBANK Holdings Inc. ("SBH"). Because of these relationships, it
is possible that the terms of the various transactions are not those that
would result from an arm's length dealing among unrelated parties.
   
  In December 1994, as part of the acquisition of ZD Expos, MAC purchased a
portion of the trade show assets for $45 million and its parent company, Son
Kosan Ltd., purchased an additional portion for $10 million. Son Kosan's trade
show assets were sold to SB Forums for $30 million in January 1997 and certain
of MAC's trade show assets are being contributed to ZDCF as part of the
Reorganization. See "The Reorganization."     
 
  In February 1996, as part of the acquisition of ZD Pubco, MAC purchased
certain publishing assets for $302 million in cash. Concurrently with the sale
of assets, ZDI and MAC entered into a management agreement pursuant to which
ZDI agreed to provide management services with respect to the purchased
assets. The Company earned approximately $2 million for such services for each
of the years ended December 31, 1996 and 1997, respectively. Of these assets,
a portion was transferred to ZDI for $100 million as of October 31, 1997 and
the balance will be sold to ZDI for $270 million concurrently with the
Offering. See "The Reorganization." The purchase price for the assets sold to
ZDI was not more than fair market value as determined by an independent
appraiser.
 
 
                                      64

  ZDI and Softbank entered into a series of license and syndication agreements
pursuant to which Softbank was granted the license to publish, or use certain
materials from, PC Week, Computer Shopper, PC Computing, MacWeek, Computer
Gaming World, PC Magazine and Internet Business Advantage. The Company earned
approximately $963,948 and $1,817,986 in connection therewith for the years
ended December 31, 1996 and 1997, respectively. Such agreements are being
combined into the master license agreement described above.     
   
  The Company has advanced funds for the account of MAC in managing the MAC
Assets and ZDTV, bearing interest at the 30-day LIBOR rate plus .50%; subject
to periodic reimbursement by MAC. Such advances totalled $8.1 million, $68.2
million and $70.9 million in 1995, 1996 and 1997, respectively. The remaining
outstanding amount as of December 31, 1997 of $42.6 million will be reimbursed
in connection with the Reorganization. See Note 9 to the Notes to the Combined
Financial Statements of ZDI and ZDCF.     
 
  During 1996 and 1997, the Company recorded revenues of approximately $.9
million and $2.7 million, respectively, from sales of advertising space and
trade show services to Kingston, an 80%-owned Softbank partnership. These
services were provided under terms consistent with those provided to
unaffiliated customers. See Note 9 of the Notes to the Combined Financial
Statements. Concurrently with the Offering the Company is entering into a
sale-leaseback transaction with Kingston. See "The Reorganization."
 
  In 1997 the Company had an arrangement with SOFTBANK Interactive Marketing
("SIM"), a 65.3%-owned Softbank subsidiary, for providing interactive media
sales. The Company paid SIM approximately $.6 million and $1.8 million in
commissions for the years ended December 31, 1996 and 1997, respectively.
Effective December 31, 1997, SIM was acquired by an unrelated third party and
the Company terminated its representation agreement with SIM. See Note 9 of
the Notes to the Combined Financial Statements of ZDI and ZDCF.
 
  During 1996 and 1997, the Company and Softbank were parties to a joint
venture agreement pursuant to which the Company managed all ZDCF trade shows
and conferences conducted in Japan. The Company earned approximately
$1,727,000 and $1,413,000 for such services for the years ended December 31,
1996 and 1997, respectively.
   
  During 1996 and 1997, the Company incurred $2 million and approximately $1.6
million in advertising expenses with Yahoo! Inc., which is 29.4% owned by
Softbank. Mr. Yang is a co-founder and Chief Yahoo and Mr. Hippeau is a
director of Yahoo! Inc.     
 
  During 1995 to 1997, the Company issued notes payable to Softbank in an
aggregate principal amount of $2.5 billion as of December 31, 1997,
principally for indebtedness incurred in the acquisition of ZD Expos, COMDEX
and ZD Pubco. See Note 9 of the Notes to the Combined Financial Statements.
 
  As part of the acquisition of the Company by its former owner in 1994, the
Company agreed to assume certain obligations to management arising out of
prior employment arrangements with Ziff Communications Company. In 1995 and
immediately after the end of the 1996 calendar year, the Company paid under
such arrangements $29,702,469 to Mr. Hippeau, the Company's Chairman and CEO
and a Director of the Company, and $1,114,565 to Mr. Sheer, the President of
ZD Publishing and a Director of the Company. See Note 8 to the Notes to the
Combined Financial Statements of ZDI and ZDCF.
 
  The Company has participated in the U.S. Softbank cash management program,
periodically transferring excess cash to SBH and in turn receiving cash
advances from SBH to fund the Company's short-term working capital
requirements. Under the program, interest is accrued based on the net balance
outstanding at the end of each month. Interest income is earned at the 30-day
LIBOR rate. Interest expense is incurred at such rate plus .50%. As of
December 31, 1996 and 1997, such net cash transfers from the Company to SBH
amounted to $41.3 million and $76.5 million, respectively. See Note 9 of the
Notes to the Combined Financial Statements of ZDI and ZDCF.
 
  During 1997, the Company was a guarantor under SBH's $150 million loan
agreement with The Bank of New York, under which $102.5 million was
outstanding as of December 31, 1997, bearing interest at a weighted average
rate of 6.51% per annum. In March, 1998 this agreement was amended and
restated to increase the loan
 
                                      65
<PAGE>
 
   
amount to $450 million. Under the amended agreement, the Company is a
guarantor under SBH's $450 million credit facility with The Bank of New York,
as agent, The Bank of New York and Morgan Stanley Senior Funding, Inc., as
lenders, and certain affiliate guarantors. The agreement governing the credit
facility contains certain restrictive covenants and other provisions which
bind the Company, but it does not prevent the Company from consummating the
Offering. Concurrently with the Reorganization, the Company will repay
obligations due to SBH; and it is expected that SBH will use a portion of such
proceeds to prepay the loans under the credit facility and terminate the
commitments thereunder.     
 
  SBH and its subsidiary SBH Delaware have agreed to act as guarantors for
payments under the Company's lease for its new headquarters located at 28 East
28th Street, New York, New York. In addition, the various intercompany loans
from SBH Delaware to the Company were subordinated to the lease agreement. In
accordance with the terms of these agreements, these arrangements will
terminate when the Company and SBH meet minimum net worth levels of $850
million and $715 million, respectively, upon completion of the Offerings, at
which time the Company will become the sole guarantor under the lease.
 
  During 1997, the Company entered into an operating lease with GE Capital
Corp. for certain television production equipment that the Company subleased
to ZDTV on similar terms. This arrangement is expected to continue upon
completion of the Offering. The total amount of leased equipment will not
exceed $10 million.
 
  During 1997, the Company participated in a global insurance program
implemented by SBH. Upon completion of the Offering, it is expected that the
Company will remain a part of this program. The total amount of insurance
expenses allocated to the Company for the period from August 1, 1997 to July
30, 1998 does not exceed $1.35 million.

  The Company is a newly organized Delaware corporation, incorporated on
February 4, 1998, with no stock issued prior to the Reorganization. SBH is a

                          DESCRIPTION OF CAPITAL STOCK
   
  The following summary of certain provisions of the Company's capital stock
describes all material provisions of, but does not purport to be complete and
is subject to, and qualified in its entirety by, the Company's Certificate of
Incorporation and By-laws, copies of which have been filed as exhibits to the
Registration Statement of which this Prospectus forms a part and by the
provisions of applicable law. See "Additional Information."     
   
  At the time of the Offering, the total amount of authorized capital stock of
the Company will be 120 million shares, consisting of 110 million shares of
Common Stock, par value $.01 per share, and 10 million shares of Preferred
Stock, par value $.01 per share (the "Preferred Stock"). Upon completion of the
Offering, 100 million shares of Common Stock and no shares of Preferred Stock
will be issued and outstanding. As of April 1, 1998, there were no shares of
Common Stock outstanding. The discussion herein describes the Company's Amended
and Restated Certificate of Incorporation (the "Certificate of Incorporation")
and By-laws, as anticipated to be in effect upon consummation of the Offering,
and their effect on the Common Stock.     
 
  Prior to the Offering, there has been no public market for the Common Stock.
See "Risk Factors--No Prior Public Market; Possible Volatility of Stock Price."
 
COMMON STOCK
 
  The issued and outstanding shares of Common Stock are, and the shares of
Common Stock being offered by the Company will be upon payment therefor,
validly issued, fully paid and nonassessable. The holders of outstanding shares
of Common Stock are entitled to receive dividends out of assets legally
available therefor at such time and in such amounts as the Board of Directors
may from time to time determine. See "Dividend Policy." The shares of Common
Stock are not convertible and the holders thereof have no preemptive or
subscription rights to purchase any securities of the Company. Upon
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to receive pro rata the assets of the Company which are
legally available for distribution, after payment of all debts and other
liabilities. Each outstanding share of Common Stock is entitled to one vote on
all matters submitted to a vote of the stockholders, including election of
directors. There is no cumulative voting. Except as otherwise required by law
or the Certificate of Incorporation, the Common Stock will vote on all matters
submitted to a vote of the stockholders, including election of directors.
 
PREFERRED STOCK
 
  The Certificate of Incorporation provides that shares of Preferred Stock may
be issued in one or more series from time to time by the Board, and the Board
is expressly authorized 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: (a) the distinctive serial
designation of such series which shall distinguish it from other series; (b)
the number of shares included in such series; (c) the dividend rate (or method
of determining such rate) payable to the holders of the shares of such series,
any conditions upon which such dividends shall be paid and the date or dates
upon which such dividends shall be payable; (d) 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; (e) the amount or amounts which shall be payable out of the assets
of the Company to the holders of the shares of such series upon voluntary or
involuntary liquidation, dissolution or winding up the Company, and the
relative rights of priority, if any, of payment of the shares of such series;
(f) 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 the Company or at the option of the holder
or holders thereof or upon the happening of a specified event or events; (g)
the obligation, if any, of the Company 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
 
                                       68
<PAGE>
 
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; (h)
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 the Company 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 the Company, and the price or prices or
rate or rates of exchange or conversion and any adjustments applicable
thereto; and (i) whether or not the 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. Subject to the rights of the 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 shares thereof then outstanding) by the affirmative vote of the
holders of a majority of the outstanding shares entitled to vote, irrespective
of the provisions of Section 242(b)(2) of the General Corporation Law of
Delaware or any corresponding provision hereafter enacted.
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BY-LAWS
 
 Staggered Board of Directors
 
  Following the Offering, the Board of Directors will consist of ten members.
The Certificate of Incorporation provides that the directors of the Company
will be divided into three classes, as nearly equal in number as reasonably
possible, as determined by the Board. The initial term of office of Class I
directors will expire at the first annual meeting of stockholders, the initial
term of office of Class II directors will expire at the second annual meeting
of stockholders and the initial term of office of Class III directors will
expire at the third annual meeting of stockholders, with each class of
directors to hold office until their successors have been duly elected and
qualified. At each annual meeting of stockholders, directors elected to
succeed the directors whose terms expire at such annual meeting shall be
elected to hold office for a term expiring at the annual meeting of
stockholders in the third year following the year of their election and until
their successors have been duly elected and qualified. The classification of
the Board will have the effect of making it more difficult for stockholders to
change the composition of the Board, because only a minority of the directors
are up for election at each annual meeting, and the Board may not be replaced
by vote of the stockholders at any one time.
 
 Number of Directors; Removal; Filling Vacancies
 
  The Certificate of Incorporation provides that the number of members of the
Board of Directors will be fixed from time to time pursuant to the By-laws.
The By-laws provide that the Board will consist of one or more members, the
number of which will be determined from time to time by the Board. The
Certificate of Incorporation and By-laws provide that in the event of any
increase or decrease in the authorized number of directors, (a) each director
then serving as such 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 (b) the newly created or
eliminated directorships resulting from such increase or decrease shall be
apportioned by the Board among the three classes of directors so as to
maintain such classes as nearly equal in number as reasonably possible. The
Certificate of Incorporation and By-laws provide that directors may be removed
only for cause except that a director who is also an officer may be removed
upon ceasing to be an officer. The By-laws provide that 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, or by the sole remaining director of that class if
one such director remains, or by the majority vote of the directors of the
remaining classes if no such director remains, or by stockholders at an annual
meeting of stockholders of the Company. A director elected to fill a vacancy
shall serve for the remainder of the then present term of office of the class
to which he is elected. These provisions would prevent any stockholder from
enlarging the Board and then filling the new directorships with such
stockholder's own nominees.
 
                                      69
<PAGE>
 
 No Stockholder Action by Written Consent; Special Meetings
 
  The Certificate of Incorporation and By-laws provide that any action
required or permitted to be taken by the stockholders of the Company 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. The Certificate of
Incorporation and By-laws provide that special meetings of stockholders of the
Company may be called only by the Chairman of the Board, the Vice Chairman of
the Board, the President or the Board pursuant to a resolution stating the
purpose or purposes thereof, and 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 will 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 for consideration of such proposal.
 
 Advance Notice for Stockholder Nominations and Proposals of New Business
 
  The By-laws require notice of any proposal to be presented by any
stockholder or of the name of any person to be nominated by any stockholder
for election as a director of the Company at a meeting of stockholders to be
delivered to the Secretary of the Company not less than 60 nor more than 90
days prior to the date of the meeting. 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 Certificate of Incorporation provides that the affirmative vote of the
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 is required to amend provisions of the By-laws relating to stockholder
action without a meeting; the calling of special meetings; the number (or
manner of determining the number), election and term of the Company's
directors; the filling of vacancies; and the removal of directors.
 
CERTAIN PROVISIONS OF DELAWARE LAW
 
  Following the consummation of the Offering, the Company will be subject to
the "Business Combination" provisions of Section 203 of the DGCL. 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 which the person
became an "interested stockholder," unless: (i) the transaction is approved by
the Board of Directors prior to the date the "interested stockholder" obtained
such status; (ii) 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 (a) persons who are
directors and also officers and (b) 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
(iii) 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 the Company and, accordingly, may discourage
attempts to acquire the Company.
 
  Section 203 and the provision of the Company's Certificate of Incorporation
and By-laws described above may make it more difficult for a third party to
acquire, or discharge bids for, the Company. Section 203 and these provisions
could have the effect of inhibiting attempts to change the membership of the
Company's Board of Directors.
 
                                      70
<PAGE>
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  Section 102 of the DGCL 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 and 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 and their
stockholders for monetary damages for conduct constituting gross negligence in
the exercise of their duty of care. Although Section 102 of the DGCL does not
change a director's duty of care, it enables corporations to limit available
relief to equitable remedies such as injunction or rescission. The Company's
Certificate of Incorporation and By-laws include provisions which limit or
eliminate the personal liability of its directors to the fullest extent
permitted by Section 102 of the DGCL. Consequently, a director or officer will
not be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for (i) any breach
of the director's duty of loyalty to the Company or its stockholders, (ii)
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) unlawful payments of dividends or unlawful
stock repurchases, redemptions or other distributions and (iv) any transaction
from which the director derived an improper personal benefit.
 
  The Certificate of Incorporation and By-laws provide that the Company will
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 the Company or serves or served at the request of the Company as a
director, officer or employee. The Certificate of Incorporation and By-laws
provide that expenses, including attorneys' fees, incurred by any such person
in defending any such action, suit or proceeding will be paid or reimbursed by
the Company 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 the Company.
The inclusion of these indemnification provisions in the Company's Certificate
of Incorporation and By-laws is intended to enable the Company to attract
qualified persons to serve as directors and officers who might otherwise be
reluctant to do so.
 
  The directors and officers of the Company are insured under policies of
insurance maintained by the Company, subject to the limits of the policies,
against certain losses arising from any claim made against them by reason of
being or having been such officers or directors. In addition, the limited
liability provisions in the Certificate of Incorporation and the
indemnification provisions in the Certificate of Incorporation and 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 the Company and it stockholders.
Furthermore, a stockholder's investment in the Company may be adversely
affected to the extent the Company pays the costs of settlement and damage
awards against directors and officers of the Company pursuant to the
indemnification provisions in the Company's By-laws. The limited liability
provisions in the Certificate of Incorporation will not limit the liability of
directors under federal securities laws.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to the Offering, there has been no market for the Common Stock of the
Company. The Company can make no predictions as to the effect, if any, that
sales of shares or the availability of shares for sale will have on the market
price prevailing from the time. Nevertheless, sales of significant amounts of
Common Stock in the public market, or the perception that such sales may
occur, could adversely affect the prevailing market prices. See "Risk
Factors--Shares Eligible for Future Sale."
   
  Upon completion of the Offering, the Company expects to have 100,000,000
shares of Common Stock outstanding. Of the shares outstanding after the
Offering, the 25,800,000 shares of Common Stock (29,670,000 shares if the U.S.
Underwriters' over-allotment is exercised in full) sold in the Offering will
be freely tradeable without restriction under the Securities Act, except for
any such shares which may be acquired by an "affiliate" of the Company (an
"Affiliate"), which shares will be subject to the volume limitations of Rule
144. As defined in Rule 144, an Affiliate of an issuer is a person that,
directly or indirectly, through one or more intermediaries, controls or is
controlled by, or is under common control with, such issuer.     
   
  An aggregate of 74,200,000 shares of Common Stock held by existing
stockholders upon completion of the Offering will be "restricted securities"
(as that phrase is defined in Rule 144) and may not be resold in the absence
of registration under the Securities Act or pursuant to exemptions from such
registration, including among others, the exemption provided by Rule 144 under
the Securities Act. One year after the date of this Prospectus, such shares of
Common 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 as currently in effect, beginning 90 days after
the date of this Prospectus, if a period of at least one year has elapsed
since the later of the date the "restricted securities" were acquired from the
Company and the date they were acquired from an Affiliate, then the holder of
such restricted securities (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 of the Common Stock
(approximately 1,000,000 shares immediately after the Offering) or the average
weekly reported volume of trading of the Common Stock 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 the Company. Affiliates may sell shares not constituting restricted
shares in accordance with the foregoing volume limitations and other
requirements without regard to any holding period. Under Rule 144 (k), if a
period of at least two years has elapsed between the later of the date
restricted securities were acquired from the Company and the date they were
acquired from an Affiliate, as applicable, a holder of such restricted
securities who 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 would be entitled to
sell the shares immediately without regard to the volume limitations and other
restrictions described above.     
 
  Any employee of the Company who purchased his or her shares of Common Stock
or received an option to purchase Common Stock pursuant to a written
compensation plan or contract while the Company was not subject to the
reporting requirements of the U.S. Securities Exchange Act of 1934, as amended
(the "Exchange Act") may be entitled to rely on the resale provisions of Rule
701 under the Securities Act, which permits nonaffiliates to sell their Rule
701 shares without having to comply with the current public information,
holding period, volume limitation or notice provisions of Rule 144 and permits
Affiliates to sell their Rule 701 shares without having to comply with the
holding period provision of Rule 144, in each case beginning 90 days after the
Company became subject to the reporting requirements of the Exchange Act.
   
  The Company and Softbank entered into a Registration Rights Agreement, dated
as of April 1, 1998 (the "Registration Rights Agreement"), in connection with
the Offering. The Registration Rights Agreement provides Softbank with the
right to require the Company to register any or all of the Common Stock held
by it in a public offering pursuant to the Securities Act of 1933, as amended.
Pursuant to the Registration Rights     
 
                                      72
<PAGE>
 
Agreement, Softbank also has the right to "piggyback" or include its Common
Stock in any registration of Common Stock made by the Company.
   
  Notwithstanding the foregoing, in connection with the Offering, each of the
Company and SBH, which owns in aggregate 74.2 million shares of Common Stock,
has agreed that, without the prior written consent of Morgan Stanley & Co.
Incorporated on behalf of the Underwriters, during the period ending 180 days
after the date of the Prospectus, they will not, directly or indirectly, (i)
offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock (whether such shares or any such
securities are then owned by such person or are thereafter acquired directly
from the Company) or (ii) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of Common Stock, whether any such transaction described in clause
(i) or (ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise. The restrictions described in this paragraph
do not apply to (a) the sale to the Underwriters of the shares of Common Stock
under the Underwriting Agreement, (b) the issuance by the Company of shares of
Common 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, (c) transactions by any person
other than the Company relating to shares of Common Stock or other securities
acquired in open market transactions after the completion of the offering of
the shares, (d) the issuance of shares of Common Stock in connection with the
Reorganization, (e) the issuance of shares of Common Stock in connection with
the Company's Employee Stock Purchase Plan or (f) subject to certain
conditions, the sale of the shares of Common Stock issued in exchange for the
Kingston assets. In addition, SBH has agreed that, without the prior written
consent of Morgan Stanley & Co. Incorporated on behalf of the Underwriters,
neither it nor any of its affiliates will, during the period ending 180 days
after the date of the Prospectus, make any demand for, or exercise any right
with respect to, the registration of any shares of Common Stock or any
security convertible into or exercisable or exchangeable for Common Stock.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
   
  The following summaries of certain material provisions of the Company's
Notes and Credit Facility do not purport to be complete and are subject to,
and qualified in their entirety by, the Company's Indenture (as defined below)
and Credit Facility, copies of which have been filed as exhibits to the
Registration Statement of which this Prospectus forms a part and by the
provisions of applicable law. See "Additional Information."     
 
NOTES
 
 General
 
  The Notes are to be issued under an Indenture, to be dated as of      , 1998
(the "Indenture"), between the Company and The Bank of New York, as trustee
(the "Trustee"). The Notes are general unsecured senior subordinated
obligations of the Company, and will rank on a parity with all other unsecured
and subordinated indebtedness of the Company. The Notes will be subordinated
in right of payment to all senior indebtedness of the Company (including
indebtedness under the Credit Agreement) as well as all other Senior
Indebtedness (as defined in the Indenture).
   
  The Notes will be limited to $250,000,000 aggregate principal amount and
will mature on      , 2008. Interest on the Notes will be payable on      and
      of each year, commencing      , 1998 at the rate of  % per annum. The
Notes will be redeemable, at the Company's option, in whole or in part, at any
time after      , 2003, at redemption prices starting at   % of their
principal amount and declining to 100% of their principal amount on or after
     , 2006 plus accrued and unpaid interest. In addition, upon a change of
control of the Company, each holder of Notes will have the right to require
the Company to purchase such holder's Notes. The Company will be permitted to
redeem a portion of the Notes following one or more public equity offerings
consummated prior to      , 2001.     
 
 Covenants
   
  The Indenture contains certain restrictive covenants, including, among
others, the following: (i) a limitation on the ability of the Company 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; (ii) a limitation on the ability of the Company 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; (iii) a
limitation on the ability of the Company to suffer to exist certain dividend
and other payment restrictions affecting its Restricted Subsidiaries; (iv) a
limitation on the ability of the Company to sell or to permit any Restricted
Subsidiary to issue or sell capital stock of a Restricted Subsidiary; (v) a
limitation on the ability of the Company and its Restricted Subsidiaries to
consummate certain Asset Sales (as defined in the Indenture) unless certain
conditions are fulfilled; and (vi) 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 the Company to merge with
or to transfer all or substantially all of its assets to another person.
Except as set forth above, the Indenture does not contain any material
quantitative financial requirements. The Notes provide for acceleration upon
customary events of default.
 
CREDIT FACILITY
   
  The Company has obtained a commitment letter from The Bank of New York,
Morgan Stanley Senior Funding, DLJ Capital Funding and The Chase Manhattan
Bank to provide a $1.35 billion term Credit Facility. In connection with the
Reorganization, the Company will enter into the Credit Facility and borrow
$1.25 billion thereunder. The Credit Facility will consist of a seven year
$700 million reducing revolving credit facility (with $600 million drawn at
assets, maintenance of adequate and customary insurance coverage, consummation
of the     
 
                                      74
<PAGE>
 
   
Offerings) and a seven year $650 million term loan. The revolving credit
commitments will be reduced and the term loan will be amortized, beginning in
September 2000, by (x) 10% in 2000, in two equal quarterly installments, (y)
20% in each of 2001, 2002, 2003 and 2004 in four equal quarterly installments
and (z) 10% at final maturity in March, 2005.     
 
  The Credit Facility will contain certain customary affirmative and negative
covenants, including covenants (subject to certain exceptions) with respect
to, among other things, the delivery of financial statements and other
information, limitations on dispositions of assets, changes of business and
ownership, mergers or acquisitions, restricted payments, indebtedness, loans
and investments, and transactions with affiliates, negative pledge of
compliance with all applicable laws and regulations, and restriction on
modifications of certain agreements, charter documents or other material
documents without the consent of the lenders. The Credit Facility will also
contain certain financial covenants.
 
  The failure to satisfy any of the covenants would constitute an Event of
Default under the Credit Facility. The Credit Facility will also include other
customary events of default, including, without limitation, nonpayment,
misrepresentation in a material respect, cross-default to other indebtedness,
bankruptcy, ERISA, judgments and change of control.
 
  The Credit Facility is subject to certain terms and conditions, including
without limitation negotiation, execution and delivery of definitive financing
agreements, in each case containing terms and conditions, representations and
warranties, covenants, indemnifications, events of default and conditions to
lending. There can be no assurance as to when or whether the Credit Facility
will be entered into or as to whether the Credit Facility will contain the
terms and conditions described above, and such may contain terms and
conditions more favorable or less favorable to the Company than set forth
above.

                    CERTAIN UNITED STATES TAX CONSEQUENCES
                      TO NON-U.S. HOLDERS OF COMMON STOCK
 
  The following is a general discussion of the material United States federal
income and estate tax consequences of the ownership and disposition of Common
Stock by a person that, for United States federal income tax purposes, is a
non-resident alien individual, a foreign corporation, a foreign partnership or
an estate or trust, in each case not subject to United States federal income
tax on a net income basis in respect of income or gain from Common Stock (a
"non-U.S. holder"). This discussion does not consider the specific facts and
circumstances that may be relevant to particular holders in light of their
personal circumstances and does not address the treatment of non-U.S. holders
of Common Stock under the laws of any state, local or foreign taxing
jurisdiction. Further, the discussion is based on provisions of the United
States Internal Revenue Code of 1986, as amended (the "Code"), Treasury
regulations thereunder, and administrative and judicial interpretations
thereof, all as in effect on the date hereof and all of which are subject to
change on a possibly retroactive basis. Each prospective holder is urged to
consult a tax advisor with respect to the United States federal tax
consequences of acquiring, holding and disposing of Common Stock, as well as
any tax consequences that may arise under the laws of any state, local or
foreign taxing jurisdiction.
 
DIVIDENDS
 
  Dividends paid to a non-U.S. holder of Common Stock will be subject to
withholding of United States federal income tax at a 30% rate or such lower
rate as may be specified by an applicable income tax treaty, unless the
dividends are effectively connected with the conduct of a trade or business
within the United States (and are attributable to a United States permanent
establishment of such holder, if an applicable income tax treaty so requires
as a condition for the non-U.S. holder to be subject to United States income
tax on a net income basis in respect of such dividends). Such "effectively
connected" dividends are subject to tax at rates applicable to United States
citizens, resident aliens and domestic United States corporations, and are not
generally subject to withholding. Any such effectively connected dividends
received by a non-United States corporation may also, under certain
circumstances, be subject to an additional "branch profits tax" at a 30% rate
or such lower rate as may be specified by an applicable income tax treaty.
 
  Under currently effective United States 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 withholding discussed above and, under the current interpretation of
United States Treasury regulations, for purposes of determining the
applicability of a tax treaty rate. Under recently finalized United States
Treasury regulations that will generally be effective for distributions after
December 31, 1999 (the "Final Withholding Regulations"), however, a non-U.S.
holder of Common Stock who wishes to claim the benefit of an applicable treaty
rate would be required to satisfy applicable certification requirements. In
addition, under the Final Withholding Regulations, in the case of Common Stock
held by a foreign partnership, (x) the certification requirement would
generally be applied to the partners of the partnership and (y) the
partnership would be required to provide certain information, including a
United States taxpayer identification number. The Final Withholding
Regulations also provide look-through rules for tiered partnerships.
 
  A non-U.S. holder of Common Stock that is eligible for a reduced rate of
United States withholding tax pursuant to a tax treaty may obtain a refund of
any excess amounts currently withheld by filing an appropriate claim for
refund with the United States Internal Revenue Service.
 
GAIN ON DISPOSITION OF COMMON STOCK
 
  A non-U.S. holder generally will not be subject to United States federal
income tax in respect of gain recognized on a disposition of Common Stock
except in the following circumstances: (i) the gain is effectively connected
with a trade or business conducted by the non-U.S. holder in the United States
(and is attributable to a permanent establishment maintained in the United
States by such non-U.S. holder if an applicable income tax treaty so requires
as a condition for such non-U.S. holder to be subject to United States
taxation on a net income
 
                                      76
<PAGE>
 
basis in respect of gain from the sale or other disposition of the Common
Stock); (ii) in the case of a non-U.S. holder who is an individual and holds
the Common Stock as a capital asset, such holder is present in the United
States for 183 or more days in the taxable year of the sale and certain other
conditions exist; (iii) the Company is or has been a "United States real
property holding corporation" for federal income tax purposes and, in the
event that the Common Stock is considered "regularly traded on an established
securities market", the non-U.S. holder 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 (and is not eligible for any treaty exemption); or (iv)
the non-U.S. holder is subject to tax pursuant to certain provisions of the
Code applicable to U.S. expatriates. Effectively connected gains realized 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 such lower rate as may be
specified by an applicable income tax treaty.
 
  The Company believes it is not currently, 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 such holder's gross estate for United States federal estate tax purposes,
unless an applicable estate tax treaty provides otherwise.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  Under current law, United States information reporting requirements (other
than reporting of dividend payments for purposes of the withholding tax noted
above) and backup withholding tax generally will not apply to dividends paid
to non-U.S. holders that are either subject to the 30% withholding discussed
above or that are not so subject because an applicable tax treaty reduces such
withholding. Otherwise, backup withholding of United States federal income tax
at a rate of 31% may apply to dividends paid with respect to Common Stock to
holders that are not "exempt recipients" and that fail to provide certain
information (including the holder's United States taxpayer identification
number). Generally, unless the payor of dividends has definite knowledge that
the payee is a United States person, the payor may treat dividend payments to
a payee with a foreign address as exempt from information reporting and backup
withholding. However, under the Final Withholding Regulations, dividend
payments generally will be subject to information reporting and backup
withholding unless applicable certification requirements are satisfied. See
the discussion above with respect to the rules applicable to foreign
partnerships under the Final Withholding Regulations.
 
  In general, United States information reporting and backup withholding
requirements also will not apply to a payment made outside the United States
of the proceeds of a sale of Common Stock through an office outside the United
States of a non-United States broker. However, United States information
reporting (but not backup withholding) requirements will apply to a payment
made outside the United States of the proceeds of a sale of Common Stock
through an office outside the United States of a broker (i) that is a United
States person, (ii) that derives 50% or more of its gross income for certain
periods from the conduct of a trade or business in the United States, (iii)
that is a "controlled foreign corporation" as to the United States, or (iv)
(effective beginning January 1, 2000) 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 if, at any time during its
tax year, such foreign partnership is engaged in a United States trade or
business, unless the broker has documentary evidence in its records that the
holder or beneficial owner is a non-United States person or the holder or
beneficial owner otherwise establishes an exemption. Payment of the proceeds
of the sale of Common Stock to or through a United States office of a broker
is currently subject to both United States backup withholding and information
reporting unless the holder certifies its non-United States status under
penalties of perjury or otherwise establishes an exemption.
 
  A non-United States holder generally may obtain a refund of any excess
amounts withheld under the backup withholding rules by filing the appropriate
claim for refund with the United States Internal Revenue Service.

</TABLE>    
   
  The U.S. Underwriters and the International Underwriters, and the U.S.
Representatives and the International Representatives, are collectively
referred to as the "Underwriters" and the "Representatives," respectively. The
Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to
take and pay for all of the shares of Common Stock offered hereby (other than
those covered by the U.S. Underwriters' over-allotment option described below)
if any such shares are taken.     
   
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented and agreed that, with certain exceptions: (i)
it is not purchasing any Shares (as defined herein) for the account of anyone
other than a United States or Canadian Person (as defined herein) and (ii) it
has not offered or sold, and will not offer or sell, directly or indirectly,
any Shares or distribute any prospectus relating to the Shares outside the
United States or Canada or to anyone other than a United States or Canadian
Person. Pursuant to the Agreement between U.S. and International Underwriters,
each International Underwriter has represented and agreed that, with certain
exceptions: (i) it is not purchasing any Shares for the account of any United
States or Canadian Person and (ii) it has not offered or sold, and will not
offer or sell, directly or indirectly, any Shares or distribute any prospectus
relating to the Shares in the United States or Canada or to any United States
or Canadian Person. With respect to any Underwriter that is a U.S. Underwriter
and an International Underwriter, the foregoing representations and agreements
(i) made by it in its capacity as a U.S. Underwriter apply only to it in its
capacity as a U.S. Underwriter and (ii) made by it in its capacity as an
International Underwriter apply only to it in its capacity as an International
Underwriter. The foregoing limitations do not apply to stabilization
transactions or to certain other transactions specified in the Agreement

entity organized under the laws of the United States or Canada or of any
political subdivision thereof (other than a branch located outside the United
States and Canada of any United States or Canadian Person), and includes any
United States or Canadian branch of a person who is otherwise not a United
States or Canadian Person. All shares of Common Stock to be purchased by the
Underwriters under the Underwriting Agreement are referred to herein as the
"Shares."
 
  Pursuant to the Agreement between U.S. and International Underwriters, sales
may be made between the U.S. Underwriters and International Underwriters of
any number of Shares as may be mutually agreed. The per share price of any
Shares sold shall be the public offering price set forth on the cover page
hereof, in United States dollars, less an amount not greater than the per
share amount of the concession to dealers set forth below.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented that it has not offered or sold, and has
agreed not to offer or sell, any Shares, directly or indirectly, in any
province or territory of Canada or to, or for the benefit of, any resident of
any province or territory of Canada in contravention of the securities laws
thereof and has represented that any offer or sale of Shares in Canada will be
made only pursuant to an exemption from the requirement to file a prospectus
in the province or territory of Canada in which such offer or sale is made.
Each U.S. Underwriter has further agreed to send to any dealer who purchases
from it any of the Shares a notice stating in substance that, by purchasing
such Shares, such dealer represents and agrees that it has not offered or
sold, and will not offer or sell, directly or indirectly, any of such Shares
in any province or territory of Canada or to, or for the benefit of, any
resident of any province or territory of Canada in contravention of the
securities laws thereof and that any offer or sale of Shares in Canada will be
made only pursuant to an exemption from the requirement to file a prospectus

such Shares a notice containing substantially the same statement as contained
in this sentence.

International Underwriter has represented and agreed that (i) it has not
offered or sold and, prior to the date six months after the closing date for
the sale of the Shares to the International Underwriters, will not offer or
sell, any Shares to persons in the United Kingdom except to persons whose
ordinary activities involve them in acquiring, holding, managing or disposing
of investments (as principal or agent) for the purposes of their businesses or
otherwise in circumstances which have not resulted and will not result in an
offer to the public in the United Kingdom within the meaning of the Public
Offers of Securities Regulations 1995; (ii) it has complied and will comply
with all applicable provisions of the Financial Services Act 1986 with respect
to anything done by it in relation to the Shares in, from or otherwise
involving the United Kingdom; and (iii) it has only issued or passed on and
will only issue or pass on in the United Kingdom any document received by it
in connection with the offering of the Shares to a person who is of a kind
described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 or is a person to whom such document
may otherwise lawfully be issued or passed on.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has further represented that it has not offered or
sold, and has agreed not to offer or sell, directly or indirectly, in Japan or
to or for the account of any resident thereof, any of the Shares acquired in
connection with the distribution contemplated hereby, except for offers or
sales to Japanese International Underwriters or dealers and except pursuant to
any exemption from the registration requirements of the Securities and
Exchange Law and otherwise in compliance with applicable provisions of
Japanese law. Each International Underwriter has further agreed to send to any
dealer who purchases from it any of the Shares a notice stating in substance
that, by purchasing such Shares, such dealer represents and agrees that it has
not offered or sold, and will not offer or sell, any of such Shares, directly
or indirectly, in Japan or to or for the account of any resident thereof
except for offers or sales to Japanese International Underwriters or dealers
and except pursuant to any exemption from the registration requirements of the
Securities and Exchange Law and otherwise in compliance with applicable
 
                                      79

provisions of Japanese law, and that such dealer will send to any other dealer
to whom it sells any of such Shares a notice containing substantially the same
statement as contained in this sentence.
 
  The Underwriters initially propose to offer part of the shares of Common
Stock directly to the public at the public offering price set forth on the
cover page hereof and part to certain dealers at a price that represents a
concession not in excess of $          a share under the public offering
price. Any Underwriter may allow, and such dealers may reallow, a concession
not in excess of $               a share to other Underwriters or to certain
other dealers. After the initial offering of the shares of Common Stock, the
offering price and other selling terms may from time to time be varied by the
Representatives.
   
  The Company has granted to the U.S. Underwriters an option, exercisable for
30 days from the date of this Prospectus, to purchase up to an aggregate of
3,870,000 additional shares of Common Stock at the public offering price set
forth on the cover page hereof, less underwriting discounts and commissions.
The U.S. Underwriters may exercise such option solely for the purpose of
covering over-allotments, if any, made in connection with the offering of the
shares of Common Stock offered hereby. To the extent such option is exercised,
each U.S. Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional shares of Common
Stock as the number set forth next to such U.S. Underwriter's name in the
preceding table bears to the total number of shares of Common Stock set forth
next to the names of all U.S. Underwriters in the preceding table.     
   
  The Company has submitted an application to list the Common Stock on the New
York Stock Exchange under the symbol "ZD." In order to meet the requirements
for listing the Common Stock on the New York Stock Exchange, the Underwriters
have undertaken to meet the New York Stock Exchange's minimum distribution,
issuance and aggregate market value requirements.     
   
  At the request of the Company, the U.S. Underwriters have reserved shares of
Common Stock offered hereby for sale, at the initial public offering price, up
to 1,550,000 shares to be issued by the Company and offered hereby for
directors, officers, employees, business associates and related persons of the
Company. The number of shares of Common Stock available for sale to the
general public will be reduced to the extent such individuals purchase such
reserved shares. Any reserved shares which are not so purchased will be
offered by the U.S. Underwriters to the general public on the same basis as
the other shares offered hereby.     
   
  Each of the Company and SBH has agreed that, without the prior written
consent of Morgan Stanley & Co. Incorporated on behalf of the Underwriters,
during the period ending 180 days after the date of the Prospectus, they will
not, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell
any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant to purchase, lend, or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock
(whether such shares or any such securities are then owned by such person or
are thereafter acquired directly from the Company) or (ii) enter into any swap
or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of Common Stock, whether any such
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise. The
restrictions described in this paragraph do not apply to (a) the sale to the
Underwriters of the shares of Common Stock under the Underwriting Agreement,
(b) the issuance by the Company of shares of Common 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, (c)
transactions by any person other than the Company relating to shares of Common
Stock or other securities acquired in open market transactions after the
completion of the offering of the Shares, (d) the issuance of shares of Common
Stock in connection with the Reorganization, (e) the issuance of shares of
Common Stock in connection with the Company's Employee Stock Purchase Plan or
(f) subject to certain conditions, the sale of the shares of Common Stock
issued in exchange for the Kingston assets. In addition, SBH has agreed that,
without the prior written consent of Morgan Stanley & Co. Incorporated on
behalf of the Underwriters, neither it nor any of its affiliates will, during
the period ending 180 days after the date of the Prospectus, make any demand
for, or exercise any right with respect to, the registration of any shares of
Common Stock or any security convertible into or exercisable or exchangeable
for Common Stock.     
 
                                      80
<PAGE>
 
  The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Common Stock offered by them.
 
  In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may over-allot in
connection with the Offering, creating a short position in the Common Stock
for their own account. In addition, to cover over-allotments or to stabilize
the price of the Common Stock, the Underwriters may bid for, and purchase,
shares of Common Stock in the open market. Finally, the underwriting syndicate
may reclaim selling concessions allowed to an Underwriter or a dealer for
distributing the Common Stock in the Offering if the syndicate repurchases
previously distributed shares of Common Stock in transactions to cover
syndicate short positions, in stabilization transactions or otherwise. Any of
these activities may stabilize or maintain the market price of the Common
Stock above independent market levels. The Underwriters are not required to
engage in these activities, and may end any of these activities at any time.
 
  The Company and the Underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.
   
  The Underwriters have agreed to reimburse the Company for a portion of the
Company's expenses in connection with the Offerings.     
   
  Certain of the Underwriters from time to time perform various investment
banking services for the Company and Softbank, for which such Underwriters
receive compensation. Morgan Stanley, Merrill Lynch and DLJ are also acting as
underwriters in connection with the Notes Offering and will receive customary
discounts and commissions in connection therewith. Morgan Stanley Senior
Funding, an affiliate of Morgan Stanley, and DLJ Capital Funding, an affiliate
of DLJ, will each act as an agent and a lender under the Credit Facility and
will receive fees pursuant to the Credit Facility customary to performing such
services. In addition, Morgan Stanley Senior Funding is currently a lender to
SBH under a $450 million revolving credit facility and will receive fees
pursuant to such financing arrangement customary to performing such services.
    
PRICING OF OFFERING
 
  Prior to the Offering, there has been no public market for the Common Stock.
Consequently, the initial public offering price for the Common Stock will be
determined by negotiations between the Company and the Representatives. Among
the factors to be considered in determining the initial public offering price
will be the Company's record of operations, the Company's current financial
position and future prospects, the experience of its management, the economics
of the industry in general, the general condition of the equity securities
markets, sales, earnings and certain other financial operation information of
the Company in recent periods, the price-earnings ratios, price-sales ratios,
market prices of securities and certain financial and operating information of
companies engaged in activities similar to those of the Company. The estimated
initial public offering price range set forth on the cover page of this
Preliminary Prospectus is subject to change as a result of market conditions
and other factors.
                                 
                              LEGAL MATTERS     
 
  The validity of the Common Stock offered hereby will be passed upon for the
Company by Sullivan & Cromwell, New York, New York, U.S. counsel to the
Company. Stephen A. Grant, a partner of Sullivan & Cromwell, owns 5,350 shares
of common stock of SOFTBANK Corp., which are held in a retirement account.
Certain legal matters will be passed upon for the Underwriters by Davis Polk &
Wardwell, New York, New York.

To the Board of Directors and Stockholder of
ZD Inc.
 
  The information and capitalization of the Company described in Note 1 to the
balance sheet has not been consummated at March 27, 1998. When it has been
consummated, we would be in a position to furnish the following report:
 
    "In our opinion, the accompanying balance sheet presents fairly, in all
    material respects, the financial position of ZD Inc. at March 27, 1998
    in conformity with generally accepted accounting principles. This
    balance sheet is the responsibility of the Company's management; our
    responsibility is to express an opinion on this balance sheet based on
    our audit. We conducted our audit in accordance with generally accepted
    auditing standards which require that we plan and perform the audit to
    obtain reasonable assurance about whether the balance sheet is free of
    material misstatement. An audit includes examining, on a test basis,
    evidence supporting the amounts and disclosures in the balance sheet,
    assessing the accounting principles used and significant estimates made
    by management, and evaluating the overall balance sheet presentation.
    We believe that our audit provides a reasonable basis for the opinion
    expressed above."

                            NOTES TO BALANCE SHEET
 
1. ORGANIZATION
 
  ZD Inc. (the "Company") is a newly formed corporation incorporated in the
State of Delaware on February 4, 1998. Upon completion of the reorganization
discussed below, the Company will be a majority-owned indirect subsidiary of
SOFTBANK Corp. and affiliates ("Softbank").
 
  The Company was formed to effect the reorganization of ZDI (Ziff-Davis Inc.)
and ZDCF (ZD COMDEX and Forums Inc.), both indirect wholly-owned subsidiaries
of Softbank. The reorganization is expected to be completed in the second
quarter of 1998 and will be accounted for in a manner similar to a pooling of
interests as the Company, ZDI and ZDCF will be companies under common control.
 
  There have been no operations of ZD Inc. as of March 27, 1998, and,
accordingly, statements of ZD Inc.'s operations and cash flows have not been
included herein.
 
2. FINANCING ARRANGEMENTS
   
  The Company expects to raise approximately $400,000,000 from the initial
public offering of its Common Stock, approximately $250,000,000 in notes, and
approximately $1,250,000,000 of senior bank debt. There can be no assurances
that the expected levels of financing from the Common Stock and Notes
Offerings will be obtained.     
   
  The Company has obtained a commitment from a group of banks to enter into a
$1.35 billion Credit Facility. The Credit Facility will consist of a seven
year $700 million reducing revolving credit facility (with $600 million drawn
at closing) and a seven year $650 million term loan. The revolving credit will
be available for loans, letters of credit, and swing-line loans, subject to a
certain maximum level of borrowing. Reductions in revolving credit commitments
and term loan amortization will occur in equal quarterly amounts beginning
September, 2000 through final maturity in March, 2005. The Credit Agreement
will also provide the Company the ability to increase the revolving credit
portion by $300 million to $1 billion at any time prior to June, 2000 if the
banks agree to increase their commitments.     
 
  Loans under both the revolving credit and term loan portions of the Credit
Facility will bear interest at either LIBOR plus an applicable margin or the
Alternate Base Rate plus an applicable margin. The applicable margin will be
based on a pricing grid to be determined by the Company's ratio of total debt
to EBITDA. The Company will also pay a commitment fee on the unused portion of
the revolving credit.
 
  The funds raised will be used to retire substantially all of the existing
notes payable to Softbank and its affiliates of ZDI and ZDCF, and for the
purchase of certain assets from affiliated companies.
   
3. EMPLOYEE BENEFIT PLANS     
   
 1998 Incentive Compensation Plan     
   
  The Company adopted the 1998 Incentive Compensation Plan (the "Plan") to
provide long-term incentives for its key employees and enhance shareholder
value. The Plan provides for the issuance of up to 8,500,000 options, stock
appreciation rights, stock awards and other interests in the Company's Common
Stock. On February 13, 1998, the Company granted 5,254,700 options with an
exercise price of $16.00 per share representing the fair value of such options
at that date. Such options vest ratably over five years.     
   
 1998 Employee Stock Purchase Plan     
   
  The Company adopted the Employee Stock Purchase Plan (the "Stock Purchase
Plan") whereby eligible employees may purchase the Company's Common Stock with
after tax payroll deductions of 1% to 10% of their base pay. The price at
which shares of Common Stock will be purchased is the lesser of 85% of the
fair market value of a share of Common Stock on (i) the first business day of
a purchase period or (ii) the last business day of a purchase period. The
Company has reserved 1,500,000 shares of Common Stock for issuance under the
Stock Purchase Plan.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholder of Ziff-Davis Inc. and ZD COMDEX and
Forums Inc.
 
In our opinion, the accompanying combined balance sheets and the related
combined statements of operations, cash flows and changes in stockholder's
equity, present fairly, in all material respects, the financial position of
Ziff-Davis Inc. and ZD COMDEX and Forums Inc. and their subsidiaries (the
"Companies") at December 31, 1997 and 1996, and the results of Ziff-Davis
Inc.'s operations and cash flows for the period from February 29, 1996 to
December 31, 1996 and for the year ended December 31, 1997 and the results of
ZD COMDEX and Forums Inc.'s operations and cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Companies' management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
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 COMBINED FINANCIAL STATEMENTS
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
1. THE COMPANIES AND BASIS OF PRESENTATION
   
  The combined financial statements include the accounts of ZDI (Ziff-Davis
Inc.) and ZDCF (ZD COMDEX and Forums, Inc.) and their subsidiaries and
predecessor companies (collectively the "Companies"). The Companies are
wholly-owned indirect subsidiaries of SOFTBANK Corp. ("Softbank"), a Japanese
corporation which, as of December 31, 1997, was 50.2% owned by Mr. Son, its
President, including 43.4% directly owned by his wholly-owned holding company,
MAC Inc. ( "MAC"), also a Japanese corporation.     
 
  As further described below, the combined financial statements include the
accounts of COMDEX (formerly Softbank COMDEX, Inc.) and ZDI as of their
respective acquisition dates and Forums (formerly Softbank Forums Inc.) for
all periods presented. Effective December 31, 1997, COMDEX and Forums merged
and the surviving company was renamed ZD COMDEX and Forums Inc.
 
  The Companies operate in two business segments: (i) publishing and (ii)
trade shows and conferences.
 
 Publishing
 
  The publishing segment is engaged in publishing magazines, journals,
newsletters, electronic information products, training manuals and providing
market research about the computer industry. The publishing segment's
principal operations are in the United States and Europe, although it also
licenses or syndicates its editorial content to over 50 other publications
distributed worldwide.
 
 Trade shows and conferences
 
  The trade shows and conferences segment is engaged in the organization,
production and management of trade shows, conferences and seminars for the
computer industry. The trade shows and conferences segment's principal
operations are in the United States and to a lesser extent in Europe and Asia.
 
 Acquisition of ZDI (formerly Ziff-Davis Publishing Company and Ziff-Davis
Holdings Corp.)
 
  In February 1996, Softbank acquired the stock of Ziff-Davis Holdings Corp.
("Holdings") for an aggregate purchase price of approximately $1,800,000, plus
transaction costs. Concurrent with the acquisition, in a separate agreement,
MAC Inc., directly or through wholly-owned affiliates, acquired certain of the
assets and assumed certain of the liabilities of ZDI (the "MAC Assets") for an
aggregate purchase price of approximately $302,000.
 
  The acquisitions of ZDI by the Companies and the MAC Assets by MAC Inc. have
been accounted for as of February 29, 1996 using the purchase method of
accounting. The excess of the purchase price over the fair value of the assets
acquired and liabilities assumed was $1,922,000 and $285,000, respectively.
 
  Subsequent to the acquisition, Holdings and ZDI were merged with ZDI being
the surviving corporation.

  The pro forma results include amortization of intangible assets and interest
expense on debt assumed issued to finance the purchase. The pro forma results
are not necessarily indicative of what actually would have occurred if the
acquisition had been completed as of the beginning of the year, nor are they
necessarily indicative of future combined results.
 
 Purchase of MAC Assets
 
  In 1997, ZDI agreed to purchase certain of the MAC Assets for $370,000. The
acquisition will be effected in two tranches; the first of which closed on
October 31, 1997 and the second, which is subject to the successful completion
of an initial public offering of ZD Inc.'s Common Stock (refer to Note 18) or
upon a similar significant external financing. At December 31, 1997, ZDI has
accrued the $370,000 purchase price which has been recorded as a return of
capital.
 
  The acquisitions from MAC described above have been accounted for in a
manner similar to a pooling of interests as all entities involved are under
common control. Accordingly, the accompanying combined financial statements
include the results of operations of the MAC Assets from February 29, 1996.
Throughout these financial statements any reference to ZDI and ZDCF or the
Companies includes ZDI, ZDCF and the MAC Assets from February 29, 1996.
 
 Acquisition of Sendai
 
  On May 8, 1996, ZDI acquired substantially all of the assets and liabilities
of Sendai Publishing Group, Inc., a publisher and distributor of magazines,
books, products and computer services related to the electronic gaming
industry, for approximately $27,500, plus transaction costs. The acquisition
was accounted for as a purchase and accordingly, Sendai's results are included
in the combined financial statements since the date of acquisition. The excess
of the purchase price over assets acquired approximated $33,378. The
operations of Sendai did not have a material effect on the combined results of
operations for the year ended December 31, 1996.
 
 Acquisition of COMDEX
 
  Effective April 1, 1995, Softbank acquired the assets of the COMDEX trade
show business, now part of ZDCF, for approximately $803,000, plus transaction
costs. The acquisition has been accounted for as of April 1, 1995 using the
purchase method of accounting and accordingly COMDEX's results are included in
the combined financial statements since the date of acquisition. The excess of
the purchase price over the fair value of the assets acquired and liabilities
assumed was $849,000.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Combination
 
  The combined financial statements include the accounts of ZDI and ZDCF
including, as discussed above, the MAC Assets. All significant transactions
between these entities have been eliminated in combination.
 
  Investments in companies in which ownership interests range from 20 to 50
percent and the Companies have the ability to exercise significant influence
over the operating and financial policies of such companies are accounted for
under the equity method.
 
 Parent Company Financing
 
  As described in Note 18, Softbank announced a Reorganization and a financing
plan which includes a recapitalization of the Companies' debt and equity
structures. Prior to the consummation of the recapitalization transactions,
the Companies are dependent on funding from Softbank. At December 31, 1997,
the Companies had current liabilities which exceeded current assets by
$371,140. To the extent that the Companies are unable to fund their current
obligations as they become due from their operating cash flows, Softbank has
committed to provide additional financing or to restructure existing loan
arrangements at least through February 1999.
 
 Cash and cash equivalents
 
  The Companies consider all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
 Concentration of credit risk
 
  The Companies place its temporary cash investments with high credit quality
financial institutions. At times, such investments may be in excess of
federally insured limits. The Companies have not experienced losses in such
accounts.
 
  The Companies' advertisers and exhibitors include principally customers who
represent a variety of technology companies in the United States and other
countries. The Companies extend credit to their customers and distributors and
historically have not experienced significant losses relating to receivables
from individual customers or groups of customers.
 
 Property and equipment
 
  Property and equipment have been recorded at cost or their estimated fair
value at the date of acquisition. Depreciation is computed using the straight-
line method over the estimated useful lives of the assets which range from
three to thirty years. Leasehold improvements are amortized using the
straight-line method over the service life of the improvement or the life of
the related lease, whichever is shorter. Maintenance and repair costs are
charged to expense as incurred.
 
 Inventories
 
  Inventories, which consist principally of paper, are stated at the lower of
cost or market. Cost is determined on a first-in, first-out basis.
 
 Intangible assets
 
  Intangible assets consist principally of advertising lists, exhibitor
relationships, trademarks and trade names, and goodwill. Amortization of these
assets is computed on a straight-line basis over their estimated useful lives.
Identifiable
 
                                     F-12
<PAGE>
 
          ZDI (ZIFF-DAVIS INC.) AND ZDCF (ZD COMDEX AND FORUMS INC.)
            (WHOLLY-OWNED INDIRECT SUBSIDIARIES OF SOFTBANK CORP.)
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
intangible assets are amortized over a period of 2 to 40 years and goodwill,
which represents the excess of the purchase price over the estimated fair
values of net assets acquired, is amortized over a period of 5 to 40 years
(refer to Note 5). The Companies assess the recoverability of their intangible
assets whenever adverse events or changes in circumstances indicate that
expected future cash flows (undiscounted and without interest charges) may not
be sufficient to support the carrying amount of intangible assets. If
undiscounted cash flows are not sufficient to support the recorded assets, an
impairment is recognized to reduce the carrying value of the intangibles to
estimated recoverable values. The Companies have not experienced any
impairment of its intangible assets.
 
 Revenue recognition
 
  Advertising revenue for the Companies' publications, less agency
commissions, is recognized as income in the month that the related
publications are sent to subscribers or become available for sale at
newsstands.
 
  Circulation revenue consists of both subscription revenue and single copy
newsstand sales. Subscription revenue, less estimated cancellations, is
deferred and recognized as income in the month that the related publications
are sent to subscribers. Newsstand sales, less estimated returns, are
recognized in the month that the related publications become available for
sale at newsstands.
 
  Payments received in advance of trade shows, conferences and seminars are
initially reported on the balance sheet as deferred revenue and are recognized
as income when the events take place.
 
  Revenue generated by market research is recognized when the service is
provided.
 
  On-line revenue, predominantly advertising, is recognized evenly over the
period of the related advertising contract which corresponds to the period of
time the advertising is displayed.
 
 Operating costs and expenses
 
  Cost of production includes the direct costs of producing magazines,
newsletters and training materials, primarily paper, printing and
distribution, and the direct costs associated with organizing, producing and
managing trade shows, seminars, conferences and expositions. Selling, general
and administrative costs include subscriber acquisition costs which are
expensed as incurred. Editorial and product development costs are expensed as
incurred. Product development costs include the cost of artwork, graphics,
prepress, plates and photography for new products.
 
 Foreign currency
 
  The effect of translating foreign currency financial statements into U.S.
dollars is included in the cumulative translation adjustments account in
stockholder's equity. Gains and losses on foreign currency transactions, which
are not significant to operations, have been included in selling, general and
administrative expenses. The Companies have not historically entered into
forward currency contracts.
 
 Other non-operating income
 
  Other non-operating income includes management fee income and the Companies'
equity share of income or loss from joint ventures.
 
 Income taxes
 
  The Companies use the asset and liability approach for financial accounting
and reporting of deferred taxes.

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

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

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

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

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

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

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

 Other affiliated arrangements
 
  During the years ended December 31, 1996 and 1997, the Companies incurred
$2,000 and $1,631, advertising expense with Yahoo!, Inc. (Yahoo!), an
affiliated company. No advertising expense with Yahoo! was incurred in 1995.
 
  The Companies sell advertising space and exhibition services to Kingston
Technology Company ("Kingston"), an affiliated company. During the years ended
December 31, 1995, 1996 and 1997, the Companies recorded revenues of $0, $882
and $2,667, respectively, from sales to Kingston. These services were provided
under terms consistent with those provided to unaffiliated customers.
 
  ZDCF has entered into an agreement to manage certain trade shows and
expositions owned by Softbank and its affiliates, whereby ZDCF earns
management and licensing fees. The fees earned by ZDCF for the years ended
December 31, 1995, 1996 and 1997 were $1,979, $3,394 and $4,057, respectively.
 
  In 1996 and 1997, the Companies had an arrangement with SOFTBANK Interactive
Marketing ("SIM"), an affiliated company, for the provision of interactive
media sales. The Companies paid commissions to SIM of $600 and $1,800 during
the years ended December 31, 1996 and 1997, respectively. Effective December
31, 1997, SIM was acquired by an unrelated third party. Management believes
that the sale of SIM by Softbank will have no material impact on the
Companies.
 
  The Companies have an arrangement with SOFTBANK Services, an affiliated
company, whereby the Companies are charged for administrative services
provided plus a management fee. For the years ended December 31, 1995, 1996

publishing and distribution of Japanese language editions of certain
publications. The fees earned by ZDI for the years ended December 31, 1996 and
1997 were approximately $964 and $1,818 respectively in each year.
 
  The Companies have entered into a license and services agreement with MAC to
develop ZDTV: Your Computer Channel. ZDTV is owned by MAC, but as part of this
license and services agreement MAC has granted the Companies an option
exercisable through December 31, 1998 to purchase all of MAC's interest in
ZDTV for an amount equal to MAC's investment plus 10% per annum. The Companies
are currently funding ZDTV's operations on behalf of MAC through unsecured
advances which, for approved levels of expenditure, are to be reimbursed by
MAC. Such advances bear interest at the 30-day LIBOR rate plus .50%. The
Companies' cumulative advances, which totaled $14.4 million net of $10.1
million in repayments through December 31, 1997, will be repaid concurrently
with the Reorganization (See Note 18). The Companies have not yet determined
whether they will exercise the option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon access to sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Companies. ZDTV is not included in the
Companies' financial statements.
 
  If the Companies were to acquire a controlling interest in ZDTV from MAC,
such acquisition would be accounted for as a pooling transaction; if the
Companies were to acquire a non-controlling interest, such acquisition would
be accounted for under the equity method.
 
  ZDI has entered into operating leases for television production equipment
and has sublet such equipment to ZDTV, an affiliated company. The terms of the
subleases are substantially identical to the terms of the leases which provide
for annual lease payments totaling approximately $610 through 2003.

  See Note 18 for a discussion of the Companies' plan to restructure its debt
and equity structures.
 
 Guarantee of Softbank's U.S. debt
 
  In April 1996, Softbank signed a line of credit agreement totaling $50,000
with an independent lender for which the Companies, along with certain other
Softbank affiliates, are guarantors. In January 1997 and October 1997, this
line of credit was increased to $75,000 and $150,000, respectively. At
December 31, 1997, $102,500 was outstanding under the line of credit.
 
 Return of capital and dividends
 
  On December 15, 1996, the Companies declared a return of capital of
approximately $900,000 paid through the issuance of a note payable to a
subsidiary of Softbank and a cash dividend of $8,000 to Softbank. In 1997, the
Companies recorded a return of capital of $381,434 in connection with the
purchase price of companies under common control.

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

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

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

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

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

18. SUBSEQUENT EVENTS (UNAUDITED)
 
 Reorganization of the Companies
 
  In February 1998, Softbank announced a reorganization of the Companies (the
"Reorganization"). In connection with the Reorganization, Softbank will
contribute the common stock of ZDI and ZDCF to a newly formed company in
exchange for a majority of the new company's common stock, the balance of
which will be offered to the public. In addition, approximately $928 million
of obligations owed to Softbank will be converted to equity, approximately
$1.5 billion of notes payable to affiliates will be refinanced, the $370
million obligation for the purchase of the MAC Assets will be paid and
balances totaling approximately $42 million due from MAC will be settled. The
Reorganization is contingent upon the successful completion of the public
stock offering and refinancing of the notes payable to affiliates.
   
 Guarantee of Softbank's U.S. Debt     
 
  In March 1998, the Company increased its guarantee of Softbank's U.S. debt
from $150 million to $450 million.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholder of
   
Ziff-Davis Inc., (formerly Ziff-Davis Publishing Company)     
 
In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, cash flows and changes in stockholder's
equity, present fairly, in all material respects, the financial position of
Ziff-Davis Inc. and its subsidiaries (formerly Ziff-Davis Publishing Company
or the "Company") at December 31, 1995 and February 28, 1996, and the results
of their operations and their cash flows for the year ended December 31, 1995
and for the period from January 1, 1996 to February 28, 1996, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.
 
As discussed in Note 16 to the financial statements, the Company was acquired
by SOFTBANK Holdings Inc. on February 29, 1996.

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

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

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

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

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

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

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

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

12. EMPLOYEE BENEFIT PLANS
 
 Retirement plans
 
  ZDI and its subsidiaries maintain various defined contribution retirement
plans. Substantially all of ZDI's employees are eligible to participate in one
of the plans under which annual contributions may be made by ZDI for the
benefit of all eligible employees. Employees may also make contributions to
the plan in which they participate which, subject to certain limitations, may
be matched by ZDI up to certain specified percentages. Employees are generally
eligible to participate in a plan upon joining ZDI and receive matching
contributions after one year of employment. ZDI made contributions of $8,432
and $1,407 for the year ended December 31, 1995 and for the period ended
February 28, 1996, respectively.
 
13. SALE OF BUSINESSES
 
  During 1995, ZDI disposed of two subsidiaries and received cash
consideration of $23,508. No gain or loss was realized on the dispositions.
 
14. OPERATING LEASE COMMITMENTS
 
  ZDI is obligated under various operating leases which expire at various
dates through 2006. Future minimum rental commitments under noncancelable
operating leases are as follows:

   1996 (ten-month period).............................................. $15,771
   1997.................................................................  19,606
   1998.................................................................  18,219
   1999.................................................................  12,532
   2000.................................................................   9,611
   Thereafter...........................................................  14,583
                                                                         -------
     Total.............................................................. $90,322

</TABLE>
 
  Netted in the above totals is approximately $2,300 for which ZDI has
noncancelable subleases in place. Total sublease income approximates ZDI's
required payments under the related leases. Rent expense amounted to
approximately $22,900 and $4,020 for the year ended December 31, 1995 and for
the period from January 1, 1996 to February 28, 1996, respectively.
 
15. CONTINGENCIES
 
  ZDI is subject to various claims and legal proceedings arising in the normal
course of business. Management believes that the ultimate liability, if any,
in the aggregate will not be material to the consolidated balance sheet,
future operations or cash flows.
 
16. SUBSEQUENT EVENTS
 
 Acquisition of the Company
 
  In February 1996, SOFTBANK Corp. entered into an agreement to acquire the
stock of ZDI for an aggregate purchase price of approximately $1,800,000, plus
transaction costs. In a separate agreement, MAC Inc. Ltd., an affiliated
company of SOFTBANK Corp., acquired directly and through affiliates, certain
of the assets and assumed certain of the liabilities of ZDI for an aggregate
purchase price of approximately $302,000.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers as well as other employees
and individuals against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with any threatened, pending or completed actions, suits or
proceeding in which such person is made a party by reason of such person being
or having been a director, officer, employee or agent to the Registrant. The
statute provides that it is not exclusive of other rights to which those
seeking indemnification may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or otherwise. Section 6.4 of the
Registrant's By-laws provides for indemnification by the Registrant of its
directors, officers and employees to the fullest extent permitted by the
Delaware General Corporation Law.
 
  Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) for payments of unlawful dividends or unlawful stock repurchases or
redemptions, or (iv) for any transaction from which the director derived an
improper personal benefit. The Company's Certificate of Incorporation provides
for such limitation of liability.
 
  Reference is also made to Section 7(c) of the Underwriting Agreement filed
as Exhibit 1.1 to the Registration Statement for information concerning the
Underwriters' obligation to indemnify the Registrant and its officers and
directors in certain circumstances.

denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

  (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under "Item 14,
Indemnification of Directors and Officers" above, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment to the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
  (c) The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 424(b)(1) or (4) or 497(h)
  under the Securities Act shall be deemed to be part of this Registration
  Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

                                  ZIFF-DAVIS
 
                       1998 EMPLOYEE STOCK PURCHASE PLAN
 
1. PURPOSE.
 
  The purpose of the Ziff-Davis 1998 Employee Stock Purchase Plan (the "Plan")
is to provide employees of ZD Inc. (the "Company") and its Subsidiaries with
an opportunity to acquire an interest in the Company through the purchase of
common stock of the Company, par value $0.01 per share (the "Common Stock")
with accumulated payroll deductions. The Company intends the Plan to qualify
as an "employee stock purchase plan" within the meaning of Section 423 of the
Internal Revenue Code of 1986, as amended (the "Code"), and the provisions of
the Plan shall be construed in a manner consistent with the requirements of
Section 423 of the Code. For purposes of the Plan, "Subsidiary" shall mean any
corporation, if any, having the relationship to the Company described in
Section 424(f) of the Code.
 
2. ADMINISTRATION.
 
  The Plan shall be administered by a committee (the Committee) of at least
three members of the board of directors of the Company (the Board) appointed
by the Board to administer the Plan and who are "non-employee directors"
within the meaning of Rule 16b-3 as promulgated under Section 16 of the
Securities Exchange Act of 1934. A majority of the Committee shall constitute
a quorum, and the acts of the majority of such quorum shall be the acts of the
Committee. The Committee may select an administrator to whom its duties and
responsibilities hereunder may be delegated. The Committee shall have full
power and authority, subject to the provisions of the Plan, to promulgate such
rules and regulations as it deems necessary for the proper administration of
the Plan, to interpret the provisions and supervise the administration of the
Plan, and to take all action in connection therewith or in relation thereto as
it deems necessary or advisable. The Committee may correct any defect, supply
any omission or reconcile any inconsistency in the Plan in the manner and to
the extent it shall deem desirable to carry it into effect. The determinations
of the Committee in the administration of the Plan, as described herein, shall
be final, conclusive and binding on all persons, including the Company and its
Subsidiaries, its shareholders, Participants and their estates and
beneficiaries. Members of the Committee and any officer or employee of the
Company or any Subsidiary acting at the direction of, or on behalf of, the
Committee shall not be personally liable for any action or determination taken
or made in good faith with respect to the Plan, and shall, to the extent
permitted by law, be fully indemnified by the Company with respect to any such
action or determination.
 
3. ELIGIBILITY AND PARTICIPATION.
 
  (a)  Any person, including an officer, who is regularly employed by the
Company or one of its Subsidiaries (an Employee) who is an Eligible Employee
on an Offering Date (as defined in Section 5(a)) shall be eligible to become a
Participant in the Plan beginning on such Offering Date. For purposes of the
Plan, an "Eligible Employee" is any Employee of the Company or a Subsidiary
excluding:
 
    (1) any Employee who customarily is employed for twenty (20) hours per
  week or less;
 
    (2) any Employee who customarily is employed for not more than five (5)
  months in a calendar year;
 
    (3) any Employee who is a highly compensated employee (within the meaning
  of Section 414(q) of the Code) and who participates in the ZD Inc. 1998
  Incentive Compensation Plan; or
 
    (4) any Employee who (immediately after the grant of an option under the
  Plan and applying the rules of Section 424(d) of the Code in determining
  stock ownership) would own shares, and/or hold outstanding options to
  purchase shares, possessing five percent (5%) or more of the total combined
  voting power or value of all classes of shares of the Company (or its
  "parent corporation" or "subsidiary corporation" as such terms are defined
  in Section 424 of the Code).
<PAGE>
 
  (b) Any Employee who first becomes an Eligible Employee during an Offering
Period (as defined in Section 5(a)) shall be eligible to become a Participant
in the Plan as of the first day of the Offering Period occurring after the
date on which such Employee becomes an Eligible Employee.
 
  (c) An Eligible Employee shall become a Participant in the Plan by
completing a form (an Authorization Form) supplied by and delivered to the
Company by a Participant authorizing payroll deductions as set forth in
Section 6 hereof and such other terms and conditions as the Company from time
to time may determine, and filing such Authorization Form with the Company by
the date required by the Company, or by any other means prescribed by the
Committee. Such Authorization Form shall remain in effect for subsequent
Offering Periods, until modified or terminated by the Participant.
 
  (d) A person shall cease to be a Participant upon the earliest to occur of:
 
    (1) the date the Participant ceases to be an Eligible Employee, for any
  reason;
 
    (2) the first day of the Offering Period beginning after the date on
  which the Participant ceases payroll deductions under the Plan; or
 
    (3) the date of a withdrawal from the Plan by the Participant.
 
4. SHARES SUBJECT TO PLAN.
 
  (a) The maximum number of shares of Common Stock reserved for sale under the
Plan shall be 1,500,000, subject to adjustment as provided in Section 13. If
the total number of shares which would otherwise be subject to options granted
pursuant to Section 5(a) on an Offering Date exceeds the number of shares then
available under the Plan (after deduction of all shares for which options have
been exercised or are then outstanding), the Committee shall make a pro rata
allocation of the shares remaining available for option grant in as uniform a
manner as shall be practicable and as it shall determine in its sole
discretion to be equitable. In such event, the Committee shall give written
notice to each Participant of such reduction of the number of option shares
affected thereby and shall similarly reduce the rate of payroll deductions, if
necessary. The Plan shall terminate upon the issuance of the maximum number of
shares of Common Stock (unless sooner terminated under Section 14).
 
  (b) Shares of Common Stock to be delivered to a Participant under the Plan
shall be registered in the name of the Participant or, at the election of the
Participant, in the name of the Participant and another person as joint
tenants with rights of survivorship.
 
5. GRANT OF OPTION.
   
  (a) On each Offering Date the Company shall grant each Eligible Employee an
option to purchase shares of Common Stock, and each Eligible Employee shall
have the same rights and privileges under the Plan, subject only to the
limitations set forth in Sections 4, 5(b), and 5(c). For purposes of the Plan,
Offering Date means the first business day of any period of time (the Offering
Period) as determined from time to time by the Committee during the
effectiveness of the Plan during which options to purchase shares of Common
Stock are granted to Participants.     
 
  (b) The option price per share of Common Stock in respect of any Offering
Period shall be an amount equal to the lesser of: (i) eighty-five percent
(85%) of the Fair Market Value of a share of Common Stock on the Offering Date
or (ii) eighty-five percent (85%) of the Fair Market Value of a share of
Common Stock on the last business day of such Offering Period (the Exercise
Date). For purposes of the Plan, "Fair Market Value" shall mean, per share of
Common Stock, the closing price of the Common Stock on the New York Stock
Exchange (the "NYSE") on the applicable date, or, if there are no sales of
Common Stock on the NYSE on such date, then the closing price of the Common
Stock on the last previous day on which a sale on the NYSE is reported.
       
                                       2
<PAGE>
 
  (c) No Participant shall be granted an option which permits such
Participants rights to purchase Common Stock under all employee stock purchase
plans of the Company to accrue at a rate which exceeds $25,000 of the Fair
Market Value of the Common Stock (determined at the time the option is
granted) for each calendar year in which such stock option is outstanding at
any time.
 
6. PAYROLL DEDUCTIONS.
   
  A Participant may, in accordance with rules adopted by the Committee, submit
an Authorization Form that authorizes a payroll deduction of any whole
percentage (from one (1) percent to ten (10) percent) of such Participant's
Compensation (as defined below) on each pay period during the Offering Period.
A Participant may increase, decrease or cease such payroll deduction effective
as of the beginning of each calendar quarter, provided such Participant files
with the Company an Authorization Form requesting such change by the date
required by the Company. For purposes of the Plan, Compensation means base
salary or wage, including salary deferral contributions pursuant to Section
401(k) of the Code and any amount excludable pursuant to Section 125 of the
Code, but excluding any bonus, fee, overtime pay, severance pay, or other
special emolument or any credit or benefit under any employee plan maintained
by the Company or any Subsidiary. All payroll deductions made by a Participant
shall be credited to such Participant's account under the Plan.     
 
7. EXERCISE OF OPTION.
 
  (a) Unless a Participant withdraws from the Plan as provided in Section 9
hereof, such Participant's election to purchase shares shall be exercised
automatically on the Exercise Date, and the maximum number of full shares
subject to such option shall be purchased for such Participant at the
applicable option price with the accumulated payroll deductions and cash
dividends (credited pursuant to Section 10 hereof) in such Participant's
account. During a Participant's lifetime, such Participants option to purchase
shares hereunder is exercisable only by such Participant.
 
  (b) The shares of Common Stock purchased upon exercise of an option
hereunder shall be credited to the Participant's account under the Plan and
shall be deemed to be transferred to the Participant on the Exercise Date and,
except as otherwise provided herein, the Participant shall have all rights of
a stockholder with respect to such shares. Notwithstanding the foregoing, in
accordance with the rules and procedures prescribed by the Committee, in lieu
of crediting shares of Common Stock to the Participants account, such shares
may be issued or transferred to the Participant.
 
  (c) Shares of Common Stock held in nominee name for the account of a
Participant shall be voted as the Participant directs.
 
8. DELIVERY OF COMMON STOCK.
 
  As promptly as practicable after receipt by the Committee of a written
request by a Participant for withdrawal of Common Stock, the Company shall
cause to be delivered to such Participant a stock certificate representing the
shares of Common Stock which the Participant requests to withdraw. Withdrawals
may be made no more frequently than once each Offering Period unless otherwise
approved by the Committee in its sole discretion.
 
 
9. WITHDRAWAL; TERMINATION OF EMPLOYMENT.
   
  (a) A Participant may withdraw all the payroll deductions and cash dividends
credited to such Participant's account (that have not been used to purchase
shares of Common Stock) under the Plan at any time by giving written notice to
the Company received at least 15 days prior to the next Exercise Date. All
such payroll deductions and cash dividends credited to such Participant's
account shall be paid to such Participant promptly after receipt of such
Participant's notice of withdrawal and such Participant's option for the
Offering Period in which the withdrawal occurs shall be automatically
terminated. No further payroll deductions for the purchase of shares of Common
Stock shall be made for such Participant during such Offering Period, and any
additional cash dividends during the Offering Period shall be distributed to
the Participant.     
       
                                       3
<PAGE>
 
   
  (b) Upon termination of a Participant's status as an Eligible Employee
during the Offering Period for any reason, including voluntary or involuntary
termination, retirement or death, the payroll deductions and cash dividends
credited to such Participant's account that have not been used to purchase
shares of Common Stock shall be returned (and any future cash dividends shall
be distributed) to such Participant or, in the case of such Participant's
death, his designated beneficiary, or if no beneficiary has been designated,
his estate, and such Participant's option with respect to such Offering Period
shall be automatically terminated. A Participant's status as an Employee shall
not be considered terminated in the case of a leave of absence agreed to in
writing by the Company (including, but not limited to, military and sick
leave), provided that such leave is for a period of not more than ninety (90)
days or reemployment upon expiration of such leave is guaranteed by contract
or statute.     
 
  (c) A Participant's withdrawal from an offering shall not have any effect
upon such Participant's eligibility to participate in a succeeding offering or
in any similar plan which may hereafter be adopted by the Company.
 
10. DIVIDENDS.
 
  (a) Cash dividends paid on Common Stock held in a Participant's account
shall be credited to such Participant's account and used in addition to
payroll deductions to purchase shares of Common Stock on the Exercise Date.
Dividends paid in Common Stock or stock splits of the Common Stock shall be
credited to the accounts of Participants. Dividends paid in property other
than cash or Common Stock shall be distributed to Participants as soon as
practicable.
 
  (b) No interest shall accrue on or be payable with respect to the payroll
deductions or credited cash dividends of a Participant in the Plan.
 
11. NONTRANSFERABILITY.
 
  Neither payroll deductions credited to a Participant's account nor any
rights with regard to the exercise of an option or to receive shares under the
Plan may be assigned, transferred, pledged or otherwise disposed of by the
Participant in any way (other than by will and the laws of descent and
distribution) by the Participant. Any such attempt at assignment, transfer,
pledge or other disposition shall be without effect, except that the Company
may treat such act as an election to withdraw funds in accordance with Section
9 hereof.
 
12. USE OF FUNDS.
 
  All payroll deductions received or held by the Company under the Plan may be
used by the Company for any corporate purpose, and the Company shall not be
obligated to segregate such payroll deductions.
 
13. ADJUSTMENT OF AND CHANGE IN STOCK.
 
  (a) 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 or exchange of shares or other corporate
change, or any distributions to common shareholders other than cash dividends,
the Committee shall in its sole discretion conclusively determine the
appropriate equitable adjustments, if any, to be made under the Plan,
including without limitation adjustments to the number of shares of Common
Stock which have been authorized for issuance under the Plan but have not yet
been placed under option, as well as the price per share of Common Stock
covered by each option under the Plan which has not yet been exercised.
       
  (b) Upon the dissolution or liquidation of the Company, or upon a
reorganization, merger or consolidation of the Company as a result of which
the Company is not the surviving corporation, or upon a sale of substantially
all of the Companys assets, or a sale or distribution of a Subsidiary, any
affected Participant will thereafter be
 
                                       4
<PAGE>
 
including without limitation adjustments to the number of shares of Common
Stock which have been authorized for issuance under the Plan but have not yet
been placed under option, as well as the price per share of Common Stock
covered by each option under the Plan which has not yet been exercised.
 
  (b) Upon the dissolution or liquidation of the Company, or upon a
reorganization, merger or consolidation of the Company as a result of which
the Company is not the surviving corporation, or upon a sale of substantially
all of the Companys assets, or a sale or distribution of a Subsidiary, any
affected Participant will thereafter be entitled to receive on the next
Exercise Date for each share of Common Stock subject to such Participants
option, the cash, securities and/or property which a holder of one share of
Common Stock was entitled to receive upon and at the time of such transaction.
The Board and the Committee shall take such steps in connection with such
transaction as the Board and the Committee respectively shall deem necessary
to assure that the provisions of this Section 13(b) shall be complied with.
 
14. AMENDMENT OR TERMINATION.
 
  The Board may at any time terminate or amend the Plan. Except as provided in
Section 4, no such termination shall adversely affect options previously
granted and no amendment may make any change in any option theretofore granted
which adversely affects the rights of any Participant. No amendment shall be
effective unless approved by the stockholders of the Company if stockholder
approval of such amendment is required to comply with any law, regulation or
stock exchange rule.
 
15. NOTICES.
 
  All notices or other communications by a Participant to the Company under or
in connection with the Plan shall be deemed to have been duly given when
received in the form specified by the Company at the location, or by the
person, designated by the Company for the receipt thereof.
 
16. GOVERNING LAW; REGULATORY APPROVALS.
 
  (a) This Plan and the rights of all persons claiming hereunder shall be
construed and determined in accordance with the laws of the State of New York
applicable to contracts made and to be performed in such State.
 
  (b) The obligation of the Company to sell or deliver shares of Common Stock
with respect to options granted under the Plan shall be subject to all
applicable laws, rules and regulations, including all applicable Federal and
state securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Committee.
 
17. NOTICE OF SALE.
 
  If the Participant makes a disposition, within the meaning of Section 424(c)
of the Code and regulations promulgated thereunder, of any share or shares
issued to such Participant pursuant to such Participant's exercise of an
option granted hereunder, and such disposition occurs within the two-year
period commencing on the day after the Offering Date or within the one-year
period commencing on the day after the Exercise Date, such Participant shall,
within five (5) days of such disposition, notify the Company thereof
(including the proceeds of such disposition).
 
18. REPORTS.
   
  Each Participant having an account balance in the Plan shall receive a
quarterly statement of such Participants account.     
 
19. EFFECTIVE DATE; APPROVAL OF STOCKHOLDERS.
 
  The Plan shall be effective as of July 1, 1998, subject to the approval of
the stockholders of the Company within 12 months before or after the date the
Plan is adopted, and failure to receive such approval shall render the Plan
and all outstanding options issued thereunder void and of no effect.

Ziff-Davis Inc.,
  One Park Avenue,
     New York, NY 10011.

Attention: Mr. Eric Hippeau, Chairman and CEO

Dear Sirs:

        In connection with the public offering of shares of Ziff-Davis Inc. 
(formerly ZD Inc., the "Company"), SOFTBANK Corp. ("SOFTBANK") undertakes that 
SOFTBANK and its subsidiaries will not expand their operations involving

                (i) publishing information on computing and Internet-related
        technology through the media of print, CD ROM/DVD, Internet and
        television, or
        
                (ii) producing trade shows, conferences, exhibitions and
        similar events primarily related to computing and Internet-related
        technology,

outside Japan in competition with the Company and its subsidiaries, without the 
prior approval of the Company's management directors in consultation with the 
independent directors. It is agreed that the term "subsidiaries" as used herein 
shall include only majority-owned subsidiaries of the Company or SOFTBANK, as 
the case may be.

        For its part, the Company undertakes that the Company and its 
subsidiaries will

                (i) not compete with SOFTBANK in Japan without the prior
        approval of SOFTBANK's Board of Directors, and will afford SOFTBANK
        full cooperation and a right of first license on all of the Company's  
        products and services in Japan, and

                (ii) identify each as a member of the SOFTBANK Group by

                of all publications, (b) primary promotional materials for
                all trade shows and conferences, and (c) the letterhead
                and calling cards of all personnel.

        The foregoing undertakings of SOFTBANK and the Company shall be in 
effect only so long as SOFTBANK maintains ownership of at least 40% of the 
outstanding voting stock of the Company and such ownership is sufficient to 
elect a majority of the Company's Board of Directors.

        Please confirm your agreement with the foregoing by signing and 
returning a copy of this letter.


                                                Very truly yours,

written notice to the TV Affiliates, to amend Exhibit B to withdraw from the
license granted herein any of the Licensed Marks which are no longer used by
Ziff-Davis (whether due to discontinuance, sale or otherwise), or for which

assist and fully cooperate with Ziff-Davis' efforts during and after the term of
this agreement to secure, protect and preserve Ziff-Davis' rights and interests
in the Licensed Marks.

     (c) Use of Licensed Marks; Quality Control by Ziff-Davis.
         ---------------------------------------------------- 

          Each TV Affiliate warrants that  it shall maintain the quality of
their respective products and  services  at a level consistent with the high
quality and standard of Ziff-Davis' products and services.  Upon Ziff-Davis'
request, the TV Affiliates shall provide to Ziff-Davis access to representative
samples of all of the TV Affiliates' uses of the Licensed Marks in connection
with their products and services.

          Each TV Affiliate acknowledges and agrees that the Licensed Marks have
an established prestige, reputation and goodwill and are of great value to Ziff-
Davis.   The TV Affiliates each warrant that it shall use the Licensed Marks in
its services and products in a responsible manner to protect and enhance the
prestige of the Licensed Marks and Ziff-Davis.   Each TV Affiliate further
warrants that it shall only use the Licensed Marks in  its services and products
in a manner consistent with Ziff-Davis trademark usage policies and Exhibit A,
as it may be amended by Ziff-Davis from time to time upon notice to the TV
Affiliates.

          on Exhibit A, as from time to time amended, (each a "Publication and
          collectively, the Publications")  in print and on CD-ROM, DVD and on
          ZDNet (as long as Licensee holds a license to publish ZDNet in the
          Territory) but not in any other platform without Licensor's consent
          which shall not be unreasonably withheld.  Licensee shall not, without
          the prior written consent of Licensor, directly or indirectly export
          or allow the export of any Foreign Edition outside of the

          Territory. Licensee shall use its best efforts in all respects in the
          promotion, publication, distribution and sale of each Foreign Edition.

               (ii)Subject to the terms and conditions set forth in this
          agreement, Licensor also hereby grants to Licensee the right during
          the term of each license to translate into and use in the Japanese

              ------------------

period of its intention to terminate the license on that expiration date.  As
used in this agreement, the term "License Year" shall mean a 12-month period

              (i) With respect to each Foreign Edition licensed hereunder,
          royalties for every six (6) month period during each License Year

          to Licensor a statement certified by an authorized officer of its
          publishing division in substantially the form of Exhibit D attached

              (iii)  Within ninety (90) days after the end of each License

interest shall accrue on all unpaid amounts at the published prime rate of the
Bank of New York per annum, or, if lower, the highest rate then permitted by New
York law from the date on which payment was due through the date on which
Licensor receives payment. Licensee agrees to pay such interest and all
collection costs.

          ------------------ 
          Foreign Editions.
          ---------------- 

         (a) During the term of each license under this agreement, Licensor
shall at Licensor's expense, send via air mail or air courier, at Licensor's
option, to Licensee five (5) copies of each issue of each Publication or
Additional Publication immediately upon publication. For purposes of this
agreement, subject to any use restrictions identified by Licensor, all editorial
items (which term includes, without limitation, graphics and artwork) from each
Publication or Additional Publication in which Licensor owns the right to
license publication by Licensee in any Foreign Edition or SB Publication shall
be referred to as "Available Material", including editorial items available on
any CD version of the Publication or Additional Publication. Available Material
shall also include Benchmarks developed by any Publication or Additional
Publication and upon request, Licensor will provide Licensee with any software
required to conduct benchmark tests.

         (b) Upon Licensee's request, Licensor shall make available to Licensee
electronic files, in a format and via a medium to be determined by Licensor, of
text, graphics and artwork that have been identified by Licensor as Available
Material.  In the event that Licensee wishes to use at reasonable cost any
editorial item from any Publication or Additional Publication that is not
Available Material, Licensor shall use reasonable efforts to obtain permission,
on Licensee's behalf, for Licensee to use that item and Licensee shall promptly
reimburse Licensor for any fees, costs or expenses paid by Licensor to obtain
such permission, provided that Licensor shall have obtained Licensee's approval
of the amount of any such fees, costs or expenses prior to having incurred them.
Licensee shall also be responsible for the cost of all film or transparency
duplication and all costs of shipping or otherwise transmitting editorial
material, including Available Material (other than the copies of the

                                       6
<PAGE>
 
         (c) Notwithstanding any provision in this agreement to the contrary, if
Licensor is notified or believes that there is a likelihood of a suit or claim
relating to any item of Available Material, Licensor reserves the right not to
provide Licensee with such item and to revoke by notice to Licensee the right to
publish such item.  Licensee shall not publish that item after receipt from
Licensor of such notice.  Any action by Licensee in breach of this Section 6(c)
shall be at Licensee's own risk.

         (d) In no event shall Licensee publish and distribute any Available
Material in any Foreign Edition or SB Publication prior to the publication and
distribution of such material by Licensor in the corresponding  Publication or
Additional Publication.

         (e) Licensee shall cause the translation of Available Material to be
made faithfully and accurately by a reasonably competent translator. Licensee,
if requested to do so, shall submit its translation to Licensor for review and
comment. Notwithstanding the foregoing, Licensee may edit Available Material so
long as the resulting changes do not affect the meaning of any item of Available
Material and are required (i) by any governmental authority, or (ii) in
Licensee's reasonable judgment, to fit space or similar editorial requirements
for publication or to render any item of Available Material more readily
comprehensible in style or language to the readers of the Foreign Edition or the
SB Publication. Any information relating to authorship credit, trademarks or
copyrights shall not be changed for any reason and must be included.

         (f) In addition to Available Material from Publications, Licensee may
also include in any Foreign Edition other material prepared by Licensee or
purchased or licensed from other parties (the "Other Material"), provided that
the standard, content and quality of the Other Material is reasonably consistent
with the standard, content and quality of the corresponding Publication or
Publications; provided further that if Licensee wishes to include in any Foreign
Edition material which is not created specifically for such Foreign Edition,
Licensee shall first obtain Licensor's prior written consent.

         (g) During the term of each license hereunder, upon request, Licensor
shall provide Licensee with a reasonable amount of editorial and sales training
support, and marketing and promotional assistance for each Foreign Edition.
Licensee shall bear all of Licensor's reasonable out-of-pocket expenses in
providing such support or assistance, including, without limitation, reasonable
travel and per diem expenses for support or assistance provided outside of the
United States.

<PAGE>
 
         (h) In no event may the Available Material contained in any SB
Publication exceed 25% of the total edit material in that SB Publication.

     7.  Identification of Foreign Edition.  The front cover of each issue of
         ---------------------------------                                   
any Foreign Edition shall bear the title set forth in Exhibit A, and all the
trademarks  and logos set forth in Exhibit B, all in accordance with the
standards for form, size, logo, color  and position set forth in Exhibit B, and
language identifying the Foreign Edition as the Japanese edition or derivative
of the Publication. Licensee will take reasonable steps to insure that all
references to the Trademarks and any other trademarks of Licensor or its
affiliates in the editorial content of any Foreign Edition, including articles,
headlines and section headlines, and on the cover of any Foreign Edition and in
advertising, publicity and promotional materials, and any editorial references
to any other trademarks of Licensor or its affiliates, are consistent with
proper trademark usage, Exhibit B and such other guidelines of Licensor on such
usage as are communicated by Licensor to Licensee in writing from time to time.

     8.  Quality Standards and Quality Control; Conflict of Interest.
         ----------------------------------------------------------- 

         (a) All aspects of the publication and distribution of each Foreign
Edition, including, but not limited to, all aspects of advertising (including
advertisers, products advertised, advertising copy, sales practices and terms),
all aspects of editorial content, design and structure (including design, art
work, layout and design and copy lines of the front cover), all aspects of
manufacturing and production (including paper, printing and binding), and all
advertisements, publicity and promotional material regarding such Foreign
Edition, including, without limitation, premium disks and CD-ROMs, shall be of a
standard, content and quality that meets or exceeds the standard, content and
quality of the Publication, and that does not, in all material respects,
adversely reflect upon the reputation, integrity and high standing of the
Publication and Licensor or its affiliates or infringe or adversely affect the
value or reputation of or misuse any of the Trademarks or any other trademarks
of Licensor or its affiliates.

         (b) Licensee shall, at its expense, send by air mail to Licensor five
(5) copies of each issue of each Foreign Edition published by Licensee promptly
after its publication so that Licensor may verify the continued overall quality
of the same.

         (c) Licensee shall not engage in any actual or apparent conflict of
interest which would tend to create an impression in the minds of the public,
and especially readers of and advertisers in computer publications, that any
Foreign Edition is not an impartial, independent publication.  The sale by
Licensee or its subsidiaries or affiliates of computer hardware or 

                                       8
<PAGE>
 
software shall not by itself be deemed a conflict of interest under this Section
8(c), provided such activity does not affect the impartiality or the
independence of any Foreign Edition.

     9.  Specific Advertising Matters.
         ---------------------------- 

         (a) In the event that advertising in any Foreign Edition is sold in
combination with one or more of Licensee's other publications, the revenues from
such a combined sale shall be allocated among all publications involved in that
sale on the ratio of the then current one-time full page black and white rate
card rates for those publications.

         (b) For the purpose of calculating Net Revenue, any barter
advertisement (i.e., any advertisement for which Licensee receives consideration
in a form other than cash) shall be deemed to have generated revenues at the
average page rate for the issue in which the advertisements appeared and any
house advertisements (i.e., advertisements promoting Licensee's own products
and/or services) in excess of two (2) pages per issue of the Foreign Edition,
shall be deemed to have generated revenues at the greater of (x) the amount
charged by Licensee to its divisions for those advertisements and (y) the paper,
printing and other production costs of such ads.

     10.  Copyright and Trademark Notice and Credit.
          ----------------------------------------- 

         (a) Each copy of each Foreign Edition shall carry the following notice
and credit on the contents or masthead page in the Japanese language: "The
Japanese edition of [the Publication] is published under license from Ziff-Davis
Inc., New York, New York. Editorial items appearing in [the Foreign Edition]
that were originally published in the U.S. Edition of [the Publication] are the
copyright property of Ziff-Davis Inc. Copyright _199_ [or other year of first
publication] Ziff-Davis Inc. All Rights Reserved. [Trademark] is a trademark of
Ziff-Davis Inc".

         (b) Each copy of each SB Publication containing Available Material

the Japanese language: "Editorial items appearing in [the SB Publication] that
were originally published in the U.S. Edition of [the Additional Publication]
are the copyright property of Ziff-Davis Inc. Copyright _199_ [or other year of
first publication] Ziff-Davis Inc. All Rights Reserved. [Trademark] is a
trademark of Ziff-Davis Inc"

     11.  Non-Competition.
          --------------- 

         (a) During the term of this agreement, Licensee shall not, directly or
indirectly, engage in the business of publishing or distributing in the
Territory any publication, in print, electronic or other form, the principal
editorial content of which is directly competitive with any 

                                       9
<PAGE>
 
Foreign Edition, provided, that nothing herein shall prevent Licensor's
continued publication of its existing publications. Nothing herein shall prevent
Licensee from licensing materials or publications from other US publishers
provided such publishers are not competitors of Licensor. If such publishers are
competitors of Licensor, Licensee shall not licensee materials or publications
without Licensor's consent, not be unreasonably withheld.

         (b) The provisions of this Section 11 shall also apply in the Territory
to the actions of and be directly binding on any company directly or indirectly
owned or controlled by or under common ownership or control with Licensee, or
which directly or indirectly owns or controls Licensee (each of the foregoing
companies shall be referred to in this agreement as a "Licensee Affiliate") to
the same extent Licensee is bound by such provisions, as if they were direct
obligations of the Licensee Affiliate and as if the Licensee Affiliate were a
party to this agreement.

         (c) The provisions of this Section 11 shall survive the expiration or
termination of this agreement.

     12.  Trademarks.
          ---------- 

         (a) Except for the permission specifically given to Licensee in this
agreement, as between Licensor and Licensee, all rights and interests in the
Trademarks remain Licensor's exclusive property.  The scope of Licensee's
permission will not be considered as expanded in any respect, by implication,
operation of law or any other means except by a writing signed by both parties.
All use of the Trademarks and any other trademarks owned by Licensor or its
affiliates at any time during or after the term of each license under this
agreement anywhere in the world (collectively, the "Other Trademarks"), and all
translations of and any marks similar to any of the foregoing (all of the
foregoing Other Trademarks, and all translations of such Other Trademarks and
any marks similar to such Other Trademarks in English or in translation, and any
marks similar to the Trademarks, in English or in translation, are hereinafter
collectively referred to as the "Ziff-Davis Marks") will accrue solely to the
benefit of Licensor or its affiliates, as the case may be.

         (b) Licensee (including all Licensee Affiliates) acknowledges that, as
between Licensee and Licensor, Licensor or its affiliate(s), as the case may be,
is the exclusive owner of the Trademarks and the Ziff-Davis Marks and of all
trademark rights related to or created by Licensee's use of the Trademarks in
any language or the Ziff-Davis Marks and agrees that it will 

                                      10
<PAGE>
 
not have or obtain, by exercising its rights under this agreement or otherwise,
any right or interest in the Trademarks or the Ziff-Davis Marks, beyond the
rights specifically given in this agreement.

         (c) Licensee agrees to use the Trademarks only in accordance with, and
subject to the restrictions set forth in, this agreement and Exhibit B and such
other guidelines as Licensor may prescribe from time to time and in a manner
that does not derogate Licensor's rights therein, and not in combination with
any other word(s) or mark(s).  Licensee shall not at any time directly or
indirectly, use or permit the use of the Trademarks or the Ziff-Davis Marks in
any way which might infringe the rights of Licensor or its affiliates therein.

         (d) Ancillary to the licenses granted under this agreement, to the
extent that any trademarks owned by Licensor or its affiliates, in addition to
the Trademarks, are used by Licensor within the editorial content of any
Publication and are included in the Available Material, Licensee shall have the
limited right to use such trademarks in the corresponding Foreign Edition during
the term of its license under this agreement, but only in connection with the
publication of Available Material in such Foreign Edition in accordance with the
terms and conditions of this agreement and only as used by Licensor in the
Publication in connection with the Available Material and only in the exact
context and form used by Licensor in the Publication in connection with the
Available Material and not in combination with any other words or marks or in
any other manner.

         (e) Licensee agrees that it shall not, directly or indirectly (i)
challenge, contest or attack the ownership by Licensor or its affiliate, of the
Trademarks or any Ziff-Davis Marks or the validity of the Trademarks or any
Ziff-Davis Marks or the license granted under this agreement, or (ii) seek to
register or claim ownership of any of the Trademarks, or any other designation
similar to the Trademarks or any copyright, trademark, including, without
limitation, the Ziff-Davis Marks, or other right of Licensor or its affiliates.

         (f) Upon Licensor's written instructions, Licensee will assist and
reasonably cooperate with Licensor's efforts to secure, protect and preserve
Licensor's rights and interests in the Trademarks, including Licensor's
procuring of copyright and trademark registrations, and Licensee will, at its
expense, execute and deliver any and all documents and perform any and all acts
related thereto, including, without limitation, the supplying of such samples
and similar materials (e.g., copies of issues of the Foreign Edition and
promotional or similar materials) as may be required in this agreement or
requested by Licensor, including, without limitation, documents and acts to
reflect or confirm Licensor's or its affiliate's exclusive ownership rights.

                                       11
<PAGE>
 
Licensee further agrees, at its expense, to execute and deliver to Licensor such
documents as Licensor may request to register or record Licensee as a Registered
User or Permitted User of such trademark rights in any jurisdiction and to
follow Licensor's instructions for proper use thereof in order that protection
and/or registrations for the trademark rights may be obtained or maintained.

         (g) During the term of this agreement, Licensee will immediately notify
Licensor in writing of any infringement or imitation of, or any other event or
claim adverse to or in violation of Licensor's or its affiliates' rights or
interests in, the Trademarks or the Ziff-Davis Marks, or any other rights,
occurring within the Territory, which comes to Licensee's attention.  Licensor
will have sole discretion to decide whether any communication or legal action is
undertaken with respect to such events or claims, and will have sole right to
control all aspects of such communication and action (including choice of
attorney and settlement). Licensee will assist and fully cooperate with Licensor
in connection with any such communications and actions, and, in connection
therewith, Licensee will execute and deliver any and all documents and perform
any and all acts related thereto.

         (h) The obligations, acknowledgments, representations, covenants and
agreements of a Licensee Affiliate under this Section 12 shall be directly
binding on such Licensee Affiliate to the same extent Licensee is bound by such
provisions, as if they were direct obligations, acknowledgments,
representations, covenants and agreements of the Licensee Affiliate and as if
the Licensee Affiliate were a party to this agreement.

     13.  Indemnities.
          ----------- 

         (a) Subject to Section 13(b) below, Licensor shall indemnify and hold
Licensee harmless from any and all loss, cost, liability, damage and expense
(including reasonable attorneys' fees and other legal costs) incurred by
Licensee on account of any suit or claim by a third party against Licensee
alleging (i) that Licensee's use of the Trademarks in accordance with the terms
and conditions hereof is an infringement of the rights of that third party in
their trademark, or (ii) that Licensee's publication in any Foreign Edition in
accordance with the terms and conditions of this agreement of any item
designated as Available Material and supplied pursuant to Section 6(a) above
(but only if the claim did not arise out of the translation or alteration by
Licensee of the Available Material) is libelous, an infringement of copyright,
or an invasion of privacy (but only to the extent that the claim would have been
actionable in the United States, it being understood that Licensor shall not be
responsible for claims of libel, infringement of copyright, or invasion of

                                      12
<PAGE>
 
privacy that may arise solely under the law of any country other than the United
States).  Licensee shall promptly advise Licensor of any such claim, shall give
Licensor the opportunity to defend, compromise or settle the same, as Licensor
in its sole discretion may determine, shall cooperate fully with Licensor in the
defense of same, and shall not settle any such claim without first obtaining
Licensor's written consent thereto.

         (b) In the event of a third party claim alleging that Licensee's use of
the Trademarks is an infringement of the rights of that third party, Licensee
shall, upon Licensor's request and at Licensee's expense, use for the title of
any Foreign Edition a modified non-infringing form of the Trademarks, or a
different title and/or logo, as designated by Licensor, which shall be the sole
and exclusive property of Licensor and licensed to Licensee by Licensor under
the terms and conditions of this agreement. If the title and/or logo of such
Foreign Edition is changed pursuant to this Section 13(b), unless restricted by
law, Licensee shall place the title and logo of the corresponding Publication in
small size print on the cover page accompanied by words indicating that such
Foreign Edition is the Japanese edition or derivative of the Publication.
Licensor shall have the right to settle any claim or action arising out of any
such third party claim in its sole discretion. Subject to Section 13(a) above,
if Licensee brings any claim or counterclaim against such third party with
respect to any of the Trademarks, or continues to use any of the Trademarks
following any judgment or settlement enjoining such use, Licensee shall
indemnify and hold Licensor and its affiliates harmless from and against any and
all loss, cost, liability, damage and expense (including reasonable attorneys'
fees and other legal costs) incurred by Licensor and its affiliates on account
of such claim, counterclaim or use. In no event may Licensee make any settlement
or compromise which may authorize or permit any third party to use any of the
Trademarks, or any element thereof, or any similar trademark in any language
without Licensor's written consent.

         (c) Licensee shall indemnify and hold Licensor and its affiliates
harmless from any and all loss, cost, liability, damage and expense (including
reasonable attorneys' fees and other legal costs) incurred by Licensor and its
affiliates on account of any third party claims or lawsuits arising out of or
relating to any of Licensee's activities hereunder (other than claims as to
which Licensor indemnifies Licensee under Section 13(a)), including, without
limitation, the claims or lawsuits arising out of or relating to the Other
Material; the mistranslation of Available Material or the marketing, promotion,
publication, sale or distribution of the Foreign Edition.

                                      13
<PAGE>
 
         (d) Notwithstanding anything to the contrary in this agreement, in no
event shall either party be liable to the other for consequential or indirect
damages, including, but not limited to damages resulting from lost profits or
goodwill, whether or not that party has been advised or is aware of the
possibility of such damages.

         (e) The provisions of this Section 13 shall survive the expiration or
termination of any license under this agreement.

     14.  Retention of Rights.  All rights not specifically granted to Licensee
          -------------------                                                  
herein are retained by Licensor.  Without limiting the generality of the
foregoing, except for the rights specifically granted to Licensee in Section
1(a) above, Licensor retains all rights in and to the Trademarks, and any
additional trademarks used by Licensee pursuant to Section 12(d) above, and all
Available Material, including, but not limited to, the right to use and exploit
the Trademarks and such additional trademarks and all Available Material
throughout the world other than the Territory, in all languages in any medium or
form.  Notwith-standing the foregoing, Licensee is authorized to use any of the
material licensed under this agreement in advertising or promotion of any
Foreign Edition or in promotional or similar products ancillary to the
publication of such Foreign Edition (for example, calendars, tee shirts, etc.).

     15.  Assignment.
          ---------- 

         (a) This agreement and all rights and obligations under this agreement
shall not, other than to a subsidiary or majority-owned affiliate or with the
prior written consent of Licensor, be assigned, sublicensed, delegated or
otherwise transferred by  Licensee or by operation of law.

         (b) This agreement shall not, without the prior written consent of
Licensee, be assigned by Licensor except to an affiliate or division or in
connection with the sale or transfer of all or substantially all of the assets
of any Publication, or the sale or transfer, merger, consolidation or similar
reorganization by Licensor of trademarks and/or other intangible property or all
or substantially all of its assets.

         (c) Subject to the foregoing, this agreement shall inure to the benefit
of the parties' successors and assigns.

     16.  Breach. If Licensee fails to timely pay to Licensor any amounts due

                               LICENSE AGREEMENT

                               As of July 1, 1997


     The parties to this agreement are (i) Mac Inc., a corporation organized and
existing under the laws of Japan acting through one of its divisions, with its
offices at 1 Athenaeum Street, Riverview Building, Cambridge, Massachusetts
02142 USA ("ZDNet"), (ii) Ziff-Davis Inc., a corporation organized and existing
under the laws of the State of Delaware, with its principal office at One Park
Avenue, New York, NY 10016 USA ("Ziff-Davis"), and (iii) SOFTBANK Corp., a
corporation organized and existing under the laws of Japan, with its principal
office at 24-1 Nihonbashi Hakozaki-cho, Chuo-ku, Tokyo 103-8501, Japan
("Licensee"). ZDNet and Ziff-Davis are collectively referred to herein as
"Licensor."

     ZDNet is an affiliate and licensee of, and managed by, Ziff-Davis. ZDNet is
the publisher in the United States of the online service entitled "ZDNet" (the
"Service").  Ziff-Davis licenses ZDNet the right to use and sublicense the ZDNet
mark and logo and other materials from its publications.

     Licensee desires to publish a localized edition of the Service using
editorial material from the Service.
     Accordingly, it is agreed:

1.   Grant of License
     ----------------

     (a)  Subject to the terms and conditions set forth in this agreement,
Licensor hereby grants to Licensee, and Licensee hereby accepts, the exclusive
license during the term of this agreement to reproduce, publicly perform,
publicly display, transmit and distribute online throughout the world via the
worldwide web from server(s) located in Japan (the "Territory") a Japanese
language edition of the 
<PAGE>
 
Service directed to residents of the Territory to be entitled "ZDNET Japan" (the
"Localized Edition"). The Licensee will not, without the prior written consent
of Licensor, promote or distribute the Localized Edition from servers outside of
the Territory or to residents outside of the Territory. Licensee shall use its
best efforts in all respects in the promotion and distribution of the Localized
Edition; provided that, subject to Sections 4(f) and 12 below, Licensee may also
promote and distribute Japanese editions of other online services from
publishers other than Licensor.

     (b)  Subject to the terms and conditions set forth in this agreement,
Licensor also hereby grants to Licensee the right during the term of this
agreement to translate into and use in the Japanese language, solely in
connection with the Localized Edition, Available Material (as defined in Section
4 below) from the Service and the right during the term of this agreement to
use, solely in connection with the Localized Edition and the advertising and
promotion of the Localized Edition in the Territory, the trademark "ZDNET" in
English and the "ZDNET" logo, as more fully described in Exhibit A hereto and as
                                                         ---------              
it may be amended from time to time by Licensor upon notice to Licensee
(collectively, the "Trademarks"). Licensee may also use a reasonable amount of
Available Material from Web sites of Licensor's print publications which are
part of the Service in corresponding licensed foreign editions of those
publications.

     (c)  Subject to the terms and conditions set forth in this agreement,
Licensor also hereby grants to Licensee the exclusive right in the Territory
during the term of this agreement to use as part of the Localized Edition
elements of the graphic user interface ("GUI") used by Licensor for the Service
(the "ZDNET GUI"), as it may be modified from time to time by Licensor.

                                       2
<PAGE>
 
     (d)  Licensor agrees to furnish Licensee with materials from any other
online service, currently or hereafter published by Licensor and, upon written
request from Licensee, to grant Licensee an exclusive license, on terms and
conditions to be agreed, to publish a Japanese language edition of such service,
subject only to rights of third parties; provided, in the event there shall be
                                         --------                             
any such rights, Licensor shall use its best efforts to obtain any consent or
permission required to allow Licensee to publish or include material in such
Japanese language edition.  In addition, Licensor agrees that Licensee shall
have a right of first refusal on all licenses with respect to publication of
Japanese language editions of any of Licensor's existing or future online
services, and that neither Licensor nor any of its  wholly owned subsidiaries
will initiate discussions with any third party in Japan with respect to possible
licensing of any such online service to such party without giving prior notice
to Licensee.  If Licensee shall terminate publication of the Localized Edition,
the license for the Localized Edition shall be terminated for any other reason,
or Licensee shall decline a right of first refusal within sixty (60) days after
Licensor's notice of such right, then Licensor shall be free to license the
right to publish the Localized Edition (or any other Licensor service) or the
right to use Available Material to any other entity in the Territory, but not on
terms more favorable than those offered to Licensee in the right of first
refusal.

2.   Term
     ----
     Unless terminated earlier pursuant to this agreement, the term of this
agreement shall be for an initial period commencing on the date set forth above
(the "Effective Date") and ending on December 31, 2004.  After the expiration of
the initial term, the term of this agreement 

                                       3
<PAGE>
 
shall be automatically extended for additional one-year periods unless either
party shall give notice to the other at least one hundred eighty (180) days
prior to the expiration of the initial or any renewal period of its intention to
terminate this agreement on that expiration date.

3.   Compensation
     ------------

     (a)  In consideration of the rights granted by Licensor under this
agreement, Licensee shall pay to Licensor royalties equal to 30% of Licensee's
Operating Income (as defined in Section 3(b) below).

     (b)  As used in this agreement, the term "Operating Income" shall mean the
total amount of net income or net loss of the Localized Edition before any
applicable income taxes (whether national, local or otherwise), determined on
the basis of financial statements prepared by Licensee in accordance with
generally accepted accounting principles in the Territory, but with the
following adjustments:  (i) the Localized Edition shall be accounted for as a
separate business; (ii) gains and losses not considered recurring in the
ordinary course of business shall be excluded; (iii) the provisions of Section
7(b) shall be applied; (iv) employee claims and similar extraordinary
liabilities not directly related to the Localized Edition shall be excluded; (v)
any payment under Licensee's indemnity obligation shall be excluded; and (vi)
general and administrative expenses charged by Licensee to the Localized Edition
shall be reasonable and shall not exceed allocations generally made by Licensee
to its other operations of comparable size.

     (c)  Licensor shall pay to Licensee (Yen)20,000,000 in marketing support in
connection with the 1997 launch of the Localized Edition. Licensor shall pay
Licensee the marketing support payment no later than April 30, 1998 or such
later date as the parties may agree.

                                       4
<PAGE>
 
     (d)  In further consideration of the rights granted by and obligations
assumed by Licensor under this agreement,  Licensor shall be entitled to sell
available advertising opportunities in the Localized Edition in an amount up to
15% of available advertising opportunities in the Localized Edition during
calendar year 1998, 12.5% during calendar year 1999, and 10% thereafter during
each calendar year of the remaining term; provided, however, that Licensor shall
have such opportunities only to the extent that Licensee shall have sufficient
advertising opportunities available.  Licensor shall be entitled to retain all
of the revenues received from the sale of such advertising; provided that
Licensor shall pay Licensee a commission on all such advertisements equal to the
following percentages of the "Net Amount" (as defined below) received by
Licensor for such advertising: 25% for advertising appearing in the Localized
Edition in calendar year 1998, 22.5% for advertising appearing in calendar year
1999, 20% for calendar year 2000 and 15% for advertising appearing thereafter in
each calendar year of the remaining term. "Net Amount" means gross advertising
revenues actually received by Licensor, less advertising agency commissions,
cash discounts, credits, make-goods and other billing adjustments and
allowances, but not Licensor's commission. The advertising opportunities made
available to Licensor shall include banners, sponsorships, micro sites, and
other opportunities and shall be available on all of the pages and sites within
the Localized Edition (other than the home page) on which Licensee sells
advertising.  Licensee shall provide Licensor with appropriate information on
the Localized Edition including the total number of impressions for each month
and quarter (or more frequently as requested by Licensor in order to satisfy any
advertiser information requirements) by advertising site and category. 
Licensee 

                                       5
<PAGE>
 
acknowledges that Licensor will sell its ads based on the level of estimated
impressions and Licensee shall promptly provide "make good" impressions for ads
sold by Licensor within its area of availabilities that do not receive the
number of impressions estimated by Licensee. Licensor shall be free to discount
from Licensee's regular rates the advertising space sold under this Section 3(d)
as part of a sale or a network or other combination of sites or for other
similar reasons which Licensor deems appropriate in the circumstances.

4.   Design and Contents of the Localized Edition
     --------------------------------------------

     (a)  Licensee shall be responsible for the design and development of the
Localized Edition; provided, however, that (i) the name of the Localized Edition
shall include the ZDNet name and logo in accordance with Exhibit A; (ii) the
                                                         ---------          
graphic user interface used by Licensee for the Localized Edition  shall be the
ZDNET GUI, as it may be modified by Licensor from time to time; and (iii)
Licensor shall have the right to specify the ad banner format used in the
Localized Edition and all changes in that format shall be subject to Licensor's
written approval (which shall not unreasonably be withheld).

     (b)  During the term of this agreement, Licensor shall on a weekly basis
send or make available electronically to Licensee, at Licensor's expense,
electronic files, in a format and in a media to be determined by Licensor, of
all material from the Service immediately upon publication.  For purposes of
this agreement, subject to any use restrictions identified by Licensor, all
editorial items (which term includes, without limitation, graphics, images and
music) from the Service in which Licensor owns the right to license publication
by Licensee in the Localized Edition shall be referred to as "Available
Material," as described in Exhibit B excluding (i) Netbuyer; (ii) GameSpot,
                           ---------                                       
Video GameSpot or  

                                       6
<PAGE>
 
any other games-related materials; (iii) ZD University; (iv) Computer Database
Plus; (v) any other content on the Service which is surcharged; or (vi) software
used to develop Available Material or used for the display or performance of
Available Material unless Licensor specifically agrees in a separate writing to
provide such material or software. In the event that Licensee wishes to use at
reasonable cost any editorial item from the Service that is not Available
Material, Licensor shall use its reasonable efforts to obtain permission, on
Licensee's behalf, for Licensee to use that item and Licensee shall promptly
reimburse Licensor for any fees, costs or expenses paid by Licensor to obtain
such permission, provided that Licensor shall have obtained Licensee's approval
of the amount of any such fees, costs or expenses prior to having incurred them.
Licensee acknowledges that Licensor is not authorizing the distribution of
shareware, demonstration software, patches or other software contained in the
Software Library part of the Service, but only Licensor's descriptions of such
software. Licensee shall be responsible for securing any necessary permission to
distribute such software and for complying with all terms and conditions on
distribution imposed by the software owners. Prior to publishing any
downloadable software in the Localized Edition, Licensee agrees to test such
software to ensure that it operates on the local versions of the relevant
platform and operating system.

     (c)  Notwithstanding any provision in this agreement to the contrary, if
Licensor is notified or believes that there is a likelihood of a suit or claim
relating to any item of Available Material, Licensor reserves the right not to
provide Licensee with such item and to revoke by notice to Licensee the right to
publish any such item.  Licensee shall not publish that item after receipt from
Licensor of such 

                                       7
<PAGE>
 
notice. Any action by Licensee in breach of this Section 4(c) shall be at
Licensee's own risk. Upon notice by Licensor of a correction to any item of
Available Material, Licensee shall use reasonable commercial efforts to make the
correction to such item as instructed by Licensor's notice, but in any event
within thirty-six (36) hours after receipt of notice from Licensor.

     (d)  In no event shall Licensee publish  any Available Material in the
Localized Edition prior to the publication of such material by Licensor on the
Service.

     (e)  Licensee shall cause the translation of Available Material to be made
faithfully and accurately by a reasonably competent translator.  Notwithstanding
the foregoing, Licensee may edit Available Material so long as the resulting
changes do not affect the meaning of any item of Available Material and are
required (i) in Licensee's reasonable judgment, to fit space or similar
editorial requirements for publication or to render any item of Available
Material more readily comprehensible in style or language to the Localized
Edition's readers, or (ii) by any governmental authority.  Any information
relating to authorship credit, trademarks, copyrights and licenses of any
Available Material shall not be changed for any reason and must be included on
the Localized Edition.  In addition, Licensee must host all of the files from
the Software Library included within Available Material on its servers within
the Territory and may not point back to the Software Library on the Service
without Licensor's prior written consent.

     (f)  In addition to Available Material from the Service, Licensee may also
include in the Localized Edition other localized material prepared by Licensee
or purchased or licensed from other parties ("Other Material"), provided that
the standard, content and quality of Other Material is 

                                       8
<PAGE>
 
reasonably consistent with the standard, content and quality of the Service.
Licensee agrees that, within sixty (60) days after the signing of this
agreement, it will enter into a license with MAC Publications LLC for the
license of MacWeek publication content which shall be included within the
Localized Edition. Without limiting the foregoing, Licensee may not include any
materials from publications or services published by competitors of Licensor or
their affiliates, which shall include without limitation, CMP, IDG, C/Net and
McGraw Hill, except that materials from MAC Publications, LLC may be included so
long as it remains a joint venture between Ziff-Davis and IDG. Immediately upon
notice from Licensor, Licensee shall remove from the Localized Edition any Other
Material Licensor reasonably deems inappropriate.

     (g)  During the term of this agreement, upon request, Licensor shall
provide Licensee with reasonable editorial and sales training support, and
marketing and promotional assistance for the Localized Edition.   Licensee shall
bear all of Licensor's reasonable out-of-pocket expenses in providing such
support or assistance, including, without limitation, reasonable travel and per
diem expenses for support or assistance provided outside of the United States.

5.   Publication of the Localized Edition
     ------------------------------------

     (a)  Immediately following the execution of this agreement, Licensee shall
obtain from the appropriate authority in the Territory a local URL for the
Localized Edition, which to the extent obtainable, shall include the word
"ZDNet". Upon termination of this agreement, Licensee shall, at Licensor's
option, transfer such URL to Licensor's designee, cancel such URL, or hold, but
not use, such URL on Licensor's behalf.

     (b)  The first screen of the Localized Edition shall bear as the title of
the Localized Edition the trademark 

                                       9
<PAGE>
 
"ZDNET" in English, and the "ZDNET" logo, all in accordance with the standards
for form, size, logo, color and position set forth in Exhibit A, and shall bear
                                                      ---------
language identifying the Localized Edition as the Japanese edition of ZDNET.

     (c) Licensee shall update the Localized Edition  at least weekly. Licensee
will be responsible for support of the Localized Edition at appropriate
technical levels, including  twenty-four (24) hours, seven (7) days a week
support for the local servers serving the Localized Edition site.  Licensee will
also at all times maintain sufficient available network bandwidth, disk and file
system throughput, computer capacity, memory capacity and application capacity
to meet the needs of users of the Localized Edition, including needs during peak
usage time and as a result of growth in usage.

     (d)  Each party shall appoint a Relationship Manager to administer this
agreement.  The Relationship Managers shall be responsible for coordination and
general review of the ongoing development and marketing of the Localized Edition
and any other issues of concern to the parties.  The Relationship Managers shall
also be responsible for coordination of delivery to Licensee and upload by
Licensee to the Localized Edition of weekly updates of the Available Material.
Each Relationship Manager shall be reasonably available to the other by
telephone or electronic mail.

     (e) Licensee shall use its best efforts to promote the Localized Edition
and to establish the Localized Edition as the leading online source of
information about computers in the Territory.

     (f)  Licensor will promote the Localized Edition by listing it on
Licensor's international page for the Service for a period of fifteen (15) days
after launch of the Localized Edition, with an active link, and by listing the
URL for the Localized Edition.

                                       10
<PAGE>
 
     (g)  Licensor may require that each filter and navigation page from the
Localized Edition and any Available Material used by Licensee link directly to a
site in the Service specified by Licensor.

6.   Quality Standards and Quality Control; Conflict of Interest
     -----------------------------------------------------------

     (a)  All aspects of the publication of the Localized Edition, including,
but not limited to, all aspects of advertising (including advertisers, products
advertised, advertising copy, sales practices and terms), all aspects of
editorial content, design and structure (including GUI design, art work, layout
and design and copy lines of the home page), all aspects of production, and all
advertisements, publicity and promotional material regarding the Localized
Edition and Licensee's Service, shall be of a standard, content and quality that
meets or exceeds the standard, content and quality of the Service and that does
not, in any material respect, adversely reflect upon the reputation, integrity
and high standing of the Service and Licensor or its affiliates or infringe or
adversely affect the value or reputation of or misuse any of the Trademarks or
any other trademarks of Licensor or  its affiliates.

     (b)  Licensee shall advise Licensor of Licensee's URLs for the Localized
Edition and Licensee's Service as soon as available so that Licensor may verify
the continued overall quality of the same.

     (c)  Licensee shall not engage in any actual or apparent conflict of
interest which would tend to create an impression in the minds of the public,
and especially users of online services and advertisers advertising in online
services, that the Localized Edition is not an impartial, independent service.
The sale by Licensee or its subsidiaries or affiliates of computer hardware or
software shall not by itself be deemed a conflict of interest under 

                                       11
<PAGE>
 
this Section 6(c), provided such activity does not affect the impartiality or
the independence of the Localized Edition.

7.   Specific Advertising Matters
     ----------------------------

     (a)  In the event that advertising in the Localized Edition is sold in
combination with one or more of Licensee's other services or its publications,
the revenues from such a combined sale shall be allocated among all services and
publications involved in that sale in the respective proportions of the then
current average ad rates paid by third parties in such services and
publications.

     (b)   For the purpose of calculating Operating Income, (i)   any house
advertisements (i.e., advertisements promoting Licensee's own products and/or
                ----                                                         
services) in excess of 5% of advertising inventory per reporting period, shall
be deemed to have generated revenues at the amount charged by Licensee to its
other divisions for those advertisements; and (ii) any barter advertisement
(i.e., any advertisement for which Licensee receives consideration in a form
- -----                                                                       
other than cash) shall be deemed to have been sold at the average cost of such
advertisement not sold for barter.

     (c)  Licensor may require that promptly after launch the Localized Edition
will have the capability to rotate advertising as on the Service; provided
Licensor provides or arranges for Licensee to obtain software for such
capability.

     (d)  Licensee shall measure and maintain records of the number of monthly
impressions, page requests, unique IP (Internet provider) addresses,
registrants, ad requests (click through), file downloads, numbers and names of
advertisers, local marketing activities, content development and similar
information on the Localized Edition, and deliver a report on such information
within thirty (30) days following the end of each calendar quarter.

     (b)  Licensee acknowledges that, as between Licensee and Licensor or an
affiliate, Licensor is the exclusive owner of the Ziff-Davis Marks and of all
trademark rights related to or created by Licensee's use of the Ziff-Davis Marks

other guidelines as Licensor may prescribe from time to time and in a manner
that does not derogate Licensor's or its affiliate's rights therein, and not in
combination with any other word(s) or mark(s).  Licensee shall not at any time
directly or indirectly use or permit the use of the Trademarks or the Ziff-Davis
Marks in any way which might infringe on the rights of Licensor or its
affiliates thereon.

     (d)  Ancillary to the licenses granted under this agreement, to the extent
that any trademarks owned by Licensor or its affiliates, in addition to the
Trademarks, are used by Licensor within the editorial content of any Service and
are included in the Available Material, Licensee shall have the limited right to
use such trademarks in the corresponding Localized Edition during the term of
its license under this agreement, but only in connection with the publication of
Available Material in such Localized Edition in accordance with the terms and
conditions of this agreement and only as used by Licensor in the Service in

contest or attack the ownership by Licensor or its affiliate, of the Trademarks
or any Ziff-Davis Marks or the validity of the Trademarks or any Ziff-Davis
Marks or the license granted under this agreement, or (ii) seek to register or
claim ownership of 

                                       14
<PAGE>
 
any of the Trademarks, or any other designation similar to the Trademarks or any
copyright, trademark, including, without limitation, the Ziff-Davis Marks, or
other right of Licensor or its affiliates.

   (f) Upon Licensor's written instructions, Licensee will assist and reasonably
cooperate with Licensor's efforts to secure, protect and preserve Licensor's
rights and interests in the Trademarks, including Licensor's procuring of
copyright and trademark registrations, and Licensee will, at its expense,
execute and deliver any and all documents and perform any and all acts related
thereto, including, without limitation, the supplying of such samples and
similar materials (e.g., copies of issues of the Localized Edition and
promotional or similar materials) as may be required in this agreement or
requested by Licensor, including, without limitation, documents and acts to
reflect or confirm Licensor's or its affiliate's exclusive ownership rights.
Licensee further agrees, at its expense, to execute and deliver to Licensor such
documents as Licensor may request to register or record Licensee as a Registered
User or Permitted User of such trademark rights in any jurisdiction and to
follow Licensor's instructions for proper use thereof in order that protection
and/or registrations for the trademark rights may be obtained or maintained.

  (g) During the term of this agreement, Licensee will immediately notify
Licensor in writing of any infringement or imitation of, or any other event or
claim adverse to or in violation of Licensor's or its affiliates' rights or
interests in, the Trademarks or the Ziff-Davis Marks, or any other rights,
occurring within the Territory, which comes to Licensee's attention. Licensee,
Licensor will have sole discretion to decide whether any communication or legal
action is undertaken with respect to such events or 

                                       15
<PAGE>
 
claims, and will have sole right to control all aspects of such communication
and action (including choice of attorney and settlement). Licensee will assist
and fully cooperate with Licensor in connection with any such communications and
actions, and, in connection therewith, Licensee will execute and deliver any and
all documents and perform any and all acts related thereto.

10.  Indemnities
     -----------

    (a)  Subject to Section 10(b) below, Licensor shall indemnify and hold
Licensee harmless from any and all loss, cost, liability, damage and expense
(including reasonable attorneys' fees and other legal costs) incurred by
Licensee on account of any suit or claim by a third party against Licensee
alleging (i) that Licensee's use of the Trademarks in accordance with the terms
and conditions hereof is an infringement of the rights of that third party in
their trademark, or (ii) that Licensee's publication in the Localized Edition in
accordance with the terms and conditions of this agreement of any item
designated as Available Material and supplied pursuant to Section 4(b) above
(but only if the claim did not arise out of the translation or alteration by
Licensee of the Available Material) is libelous, an infringement of copyright,
or an invasion of privacy (but only to the extent that the claim would have been
actionable in the United States, it being understood that Licensor shall not be
responsible for claims of libel, infringement of copyright, or invasion of
privacy that may arise solely under the law of any country other than the United
States).  Licensee shall promptly advise Licensor of any such claim, shall give
Licensor the opportunity to defend, compromise or settle the same, as Licensor
in its sole discretion may determine, shall cooperate fully with Licensor in the
defense of same, and 

                                       16

shall not settle any such claim without first obtaining Licensor's written
consent thereto.

    (b)  In the event of a third party claim alleging that Licensee's use of the
Trademarks is an infringement of the rights of that third party, Licensee shall,
upon Licensor's request and at Licensee's expense, use for the title of the
Localized Edition a modified non-infringing form of the Trademarks, or a
different title and/or logo, as designated by Licensor, which shall be the sole
and exclusive property of Licensor or its affiliate and licensed to Licensee by
Licensor under the terms and conditions of this agreement.  If the title and/or
logo of the Localized Edition is changed pursuant to this Section 10(b), unless
restricted by law, Licensee shall place the "ZDNET" title and logo in small size
print on the top page of the home page accompanied by words indicating that the
Localized Edition is the Japanese edition of the Service.  Licensor shall have
the right to settle any claim or action arising out of any such third party
claim in its sole discretion.  Subject to Section 10(a) above, if Licensee
brings any claim or counterclaim against such third party with respect to any of
the Trademarks, or continues to use any of the Trademarks following any judgment
or settlement enjoining such use, Licensee shall indemnify and hold Licensor and
its affiliates harmless from and against any and all loss, cost, liability,
damage and expense (including reasonable attorneys' fees and other legal costs)
incurred by Licensor and its affiliates on account of such claim, counterclaim
or use.  In no event may Licensee make any settlement or compromise which may
authorize or permit any third party to use any of the Trademarks, or any element
thereof, or any similar trademark in any language, or any of the Ziff-Davis
Marks, without Licensor's written consent.

any of Licensee's activities hereunder, (other than claims as to which Licensor
indemnifies Licensee under Section 10(a) above), including, without limitation,
claims or lawsuits arising out of or relating to the Other Material, the
mistranslation of Available Material or the marketing, promotion, publication,
sale or distribution of the Localization Edition.

    (d)  Notwithstanding anything to the contrary in this agreement, in no event
shall either party be liable to the other for consequential or indirect damages,
including, but not limited to damages resulting from lost profits or goodwill,
whether or not that party has been advised or is aware of the possibility of
such damages.

Exhibit A
- ---------

Guidelines for the Use of the "ZDNET" Trademark and Logo by Licensee

The "ZDNET" logo licensed under the agreement to which this Exhibit is attached
(the "Agreement") may be used by Licensee only as a composite mark with the
ZDNET trademark as specified below and on the attached, which is incorporated
herein, and only in connection with the Localized Edition and only in the exact
form and context specified by Licensor, all as more fully set forth herein and
in the Agreement.  Until Licensor directs or consents to another location, the
ZDNet logo shall be used in the manner and location as used by ZDNet on the
Service.

The "ZDNET" trademark and the "ZDNET" logo composite mark licensed under the
Agreement consists of four individual marks:

  1. the words "ZDNET"
     2. the "ZDNET' logo design, including the tilted box
     design, without
     the words "ZDNET"
  3. the "ZD" stylized type
  4. the "NET" stylized type

All rights of Licensor and all obligations of Licensee, and its Licensee
Affiliates, under the Agreement shall apply with equal force and effect to the
composite mark and the four individual marks comprising the composite mark.

The "ZDNET" logo composite mark licensed under the Agreement shall be used only
in accordance with the specifications as to placement, size and design set forth
herein and must appear as the title of the Localized Edition and always be used
in one of the three following color choices:

  1. 100% Black
  2. 91% Magenta, 87% Yellow (process color)
  3. 100% PMS 485 (match color)

The "ZDNET" trademark and the "ZDNET" logo composite mark must not be enclosed
in any way by any border may not be combined with any other word(s) or mark(s).

The ZDNET trademark shall always be written in a distinctive fashion, e.g.,

                                       29
<PAGE>
 
                                      .ZDNET (all caps)   
                                      .ZDNET (all italics)
                                      .ZDNET (bold)        

Licensee will use commercially diligent efforts to use the ZDNET trademark only
as an adjective followed by the common generic term for the mark, e.g., the
ZDNET online service, and shall not use the ZDNET trademark in the possessive.

Any additional trademarks to be used by Licensee in the Localized Edition
pursuant to Section 9(a) of the Agreement may be used only in connection with
Available Material and only in the exact context and form used by Licensor, as
more fully set forth in the Agreement.

Whenever reasonable in the context of a particular use of the trademarks
licensed under the Agreement, Licensee shall identify such trademarks as being
used under license from Licensor.

All terms used in this Exhibit which are defined in the Agreement shall have the
meaning ascribed to them in the Agreement. These guidelines may be amended from
time to time by the Licensor on written notice to Licensee.

April 1, 1998



     AGREEMENT TO PRODUCE "COMDEX/ JAPAN," "NETWORLD+INTEROP JAPAN," "WINDOWS
NT INTRANET SOLUTIONS TOKYO," "SEYBOLD SEMINARS TOKYO," "OBJECT WORLD JAPAN" AND
"NEW BUSINESS" EVENTS IN JAPAN.


     This agreement dated 1st day of April 1998 is between ZD COMDEX and
Forums, Inc., a subsidiary of ZD Inc. (herein referred as `ZDCF'), owners and
producers of  COMDEX, NetWorld + Interop, Windows NT Intranet Solutions, Seybold
Seminars and Object World events, worldwide and SOFTBANK FORUMS KK, A SUBSIDIARY
OF SOFTBANK CORP, A JAPANESE CORPORATION, (herein referred to as ("Forums"),
owners and producers of trade shows in Japan.  This agreement is intended to
govern the ownership and production of a series of annual trade exhibitions and
seminars  in Japan known as: "COMDEX/ Japan," "NetWorld + Interop Japan,"
                              -------------------------------------------
"Windows NT Intranet Solutions Tokyo," "Seybold Seminars Tokyo," "Object World
- ------------------------------------------------------------------------------
Japan" and other "New Business" events still to be determined (hereinafter the
- ------------------------------------------------------------------------------
"Events").  Pursuant to this agreement, Forums will own the Events in Japan and
- ---------                                                                      
will be responsible for the overall production and management of the Events.
ZDCF agrees to give a limited license to Forums to use the trademarks:
"COMDEX," "NetWorld + Interop", "Windows NT Intranet Solutions," "Seybold
Seminars" and "Object World" solely for the purpose of organizing the above
events in Japan, in accordance with the "Trademark License Agreement" attached
hereto and incorporated herein.  Additionally, ZDCF will provide technical
assistance and know-how to the events all as more fully set forth on the
attached Technical Assistance Agreement and incorporated herein. ZDCF will also
provide invoicing, collection and administrative services to FORUMS, related to
servicing exhibitors based outside Japan, interested in exhibiting at
COMDEX/Japan, NetWorld + Interop Japan, Windows NT Intranet Solutions Tokyo,
Seybold Seminars Tokyo ,Object World Japan and still to be determined "New
Business" events, all as more fully set forth on the attached Accounting and
Administrative Services Agreement and incorporated herein.

     Whereas, heretofore, ZDCF was a wholly-owned subsidiary of SOFTBANK Corp,
and ZDCF owned and managed the Events in Japan; and

     Whereas, Softbank Corp has elected to reorganize certain of its subsidiary
entities the end result of which will be that ZDCF will no longer be a wholly-
owned subsidiary of SOFTBANK Corp; and

     Whereas, such reorganization requires that a new business arrangement be
established between ZDCF and Softbank Corp to control the ownership and
production of the Events in Japan to assure a fair and reasonable division of
the historic profits of the Events; and

     Whereas, this agreement is intended to supercede all prior agreements
between the parties (or any predecessor entity of either party) and most
specifically, the agreement dated March 31, 1997 entitled "Agreement to Produce
COMDEX /Japan";

     Now, therefore, it is agreed as follows:
<PAGE>
 
1.  OWNERSHIP OF THE EVENTS

    It is agreed between ZDCF and SOFTBANK CORP that the Events in Japan will be
    owned by Forums. Accordingly, Forums undertakes to exert its best effort to
    organize, plan, promote, and manage all aspects of the Events, except those
    specifically reserved to ZDCF pursuant to the attached agreements.
    Specifically, Forums will be responsible for all promotion, marketing,
    sales, conference activities, operations, publications, administration,
    accounting, public relations and all other Event related activities. All
    profits and losses from the Events shall be for Forums account, and all
    payments due ZDCF by Forums shall be paid in accordance with the specific
    provisions of paragraph 3 hereof and the relevant paragraphs of the attached
    agreements.

2.   RESPONSIBILITIES OF ZDCF

     a. ZDCF shall provide technical assistance (all as more fully set forth in
        the attached Technical Assistance Agreement) to Forums to facilitate
        their production and operation of the Events. Such assistance other than
        during a specific event shall be performed at the ZDCF offices in the
        United States, as ZDCF will have no permanent presence in Japan.

     b. ZDCF will act as a sales agent for Forums outside of Japan selling
        exhibit space and related products (all as more fully set forth in the
        attached Accounting and Administrative Services Agreement) for all the
        Events. ZDCF will utilize its existing worldwide network of general
        sales agents to sell outside of the United States and Canada (except
        Japan which will be the sales territory of Forums).

     c. ZDCF will license to Forums the trademarks/service marks used in
        connection with the Events, to wit, "COMDEX," "Networld + Interop,"
        "Seybold Seminars," "Object World" and such other marks as may be owned
        or controlled by ZDCF and required for the effective promotion of the
        Events (all as more fully set forth on the attached Trademark License
        Agreement).
 
3.   FINANCIAL TERMS

     a. All working capital necessary for the efficient operation of the Events
        shall be provided by Forums.

     b. As the owner of the events, Forums shall retain all profits and be
        responsible for all losses from the Events.

     c. ZDCF shall be compensated for its services to the Events as provided in
        the several agreements attached, provided, however, that,
        notwithstanding anything to the contrary set forth in the technical
        Assistance Agreement, the Accounting and Administrative Services
        Agreement and Trademark License Agreement, each between ZDCF and Forums
        and dated of even date herewith, in no event, shall the fees paid ZDCF
        pursuant to such agreements exceed, in gross, a sum greater than 50% of
        the net (pre-tax) profits earned by Forums from the Events on an annual
        basis. The fiscal year for the combination of Events shall end on
        December 31.

     d. ZDCF and Forums shall be responsible for their respective taxes on their
        profits or fees, as the case may be.

                                       2
<PAGE>
 
     e. If the Events show a loss for the fiscal year, then such loss shall be
        borne solely by Forums.

4.  BUDGETS

    Within the sixty(60) day period next following the execution of this
    Agreement, ZDCF and Forums shall jointly develop budgets of income and
    expenses for the Events to be held in 1998. In addition to the Events
    budgets, Forums shall submit a proposed overhead budget for calendar year
    1998 and submit same to ZDCF for its reasonable approval. With respect to
    all subsequent events, Forums shall, within the sixty (60) day period next
    following the conclusion of each event, prepare a proposed budget of income
    and expenses for the next year's event and submit same to ZDCF for its
    reasonable approval. Once approved, the 1998 or subsequent year's budgets
    will become the operating budget and business plan for each of the Events,
    subject to revisions and amendments from time to time, as proposed by Forums
    and reasonably approved by ZDCF. Forums will maintain one or more separate
    bank accounts in the name of Forums or each of the Events into which all
    event revenues will be deposited and from which all event expenses will be
    paid. Forums will maintain complete and accurate books of account for all
    Event-related activities. Such books of account will be open for the
    reasonable inspection of ZDCF or its agent from time to time and at
    reasonable times.

5.  DURATION

    This Agreement shall have an indefinite term provided, however, that either
    ZDCF or Forums shall be able to terminate this Agreement by notice in
    writing to the other for the following reasons and on the following
    conditions;

     a. at any time if the other party has committed a material breach of the
        terms of this Agreement which remains unremedied 30 days after service
        of notice from the first party drawing attention to the breach and
        requiring it to be remedied:

     b. with respect to any single Event, such Event may be canceled or
        postponed upon the mutual agreement of ZDCF and Forums;

     c. in the event that either party goes into receivership or liquidation (or
        analogous corporate procedure).

     d. at any time with the mutual agreement of both ZDCF and Forums.


6.  CONSEQUENCES OF TERMINATION

    Where the Agreement has been lawfully terminated pursuant to paragraph 5 (a)
    (b) (c) hereof, then the party in breach or the party in financial distress
    shall:

          (i) be precluded from producing or marketing a trade show or
              conference in Japan using ZDCF trademarks or service marks or from
              licensing such marks to enable third parties.

     Where the Agreement has been terminated by mutual agreement of the parties,
     then Forums shall be able to own, produce or manage trade shows or
     conferences in Japan thereafter, but Forums shall not be permitted to
     utilize the ZDCF trademarks or service marks to promote such events.

2.       Registration Rights
         -------------------

         2.1      Demand Registrations.
                  --------------------

                  (a) Softbank may make three written requests to the Company to
effect a registration under and in accordance with the provisions of the
Securities Act of all or part of the Registrable Securities.

                  "Registrable Securities" shall mean the Softbank Shares and
all shares of Common Stock issued or issuable upon conversion or exercise of any
securities of the Company, which may be issued or distributed with respect to,
or in exchange for, the Softbank Shares pursuant to a stock dividend, stock
split or other distribution, merger, consolidation, recapitalization or
reclassification or otherwise, and any securities of the Company which may be
issued or distributed with respect to, or in exchange for, any such Common Stock
or such other securities pursuant to a stock dividend, stock split or other
distribution, merger, consolidation, recapitalization or reclassification or
otherwise; provided, however, that any such Registrable Securities shall cease
to be Registrable Securities when (i) a Registration Statement with respect to
the sale of such Registrable Securities has been declared effective under the
Securities Act and such Registrable Securities have been disposed of in
accordance with the plan of distribution set forth in such Registration
Statement, (ii) such Registrable Securities are distributed pursuant to Rule 144
or Rule 144A (or any similar provision then in force) under the Securities Act
or (iii) such Registrable Securities shall have been otherwise transferred, new

                                      -2-
<PAGE>
 
certificates for them not bearing a legend restricting further transfer under
the Securities Act shall have been delivered by the Company and they may be
resold without subsequent registration under the Securities Act; provided,
further, however, that any securities that have ceased to be Registrable
Securities cannot thereafter become Registrable Securities, and any security
that is issued or distributed in respect to securities that have ceased to be
Registrable Securities are not Registrable Securities.

                  Any registration requested pursuant to Section 2.1(a) shall
hereinafter be referred to as a "Demand Registration." Each request for a Demand
Registration shall specify the kind and aggregate amount of Registrable
Securities to be registered and the intended methods of disposition thereof,
which may be stated in the alternative if a shelf Registration Statement is
requested pursuant to Rule 415 under the Securities Act. The Company shall be
deemed to have effected a Demand Registration if (i) the Registration Statement
relating to such Demand Registration is declared effective by the Commission and
remains effective for at least 30 days; provided, however, that no Demand
Registration shall be deemed to have been effected if (x) such registration,
after it has become effective, is interfered with by any stop order, injunction
or other order or requirement of the Commission or other governmental agency or
court or (y) the conditions to closing specified in the purchase agreement or
underwriting agreement entered into in connection with such registration are not
satisfied or (ii) at any time after Softbank's request a Demand Registration and
prior to the effectiveness of the Registration Statement, the preparation of
such Registration Statement is discontinued or such Registration Statement is
withdrawn or abandoned at Softbank's request unless either (x) Softbank has
elected to pay and has paid to the Company in full the Registration Expenses (as
hereinafter defined) in connection with such Registration Statement or (y) such
discontinuation, withdrawal or abandonment is requested by Softbank because of
the occurrence of a significant negative change in market conditions or the
Company's business condition or prospects since the date of the initial request
for a Demand Registration.

                  (b) Priority of Demand Registrations. If the managing
                      --------------------------------
underwriter or agent of a Demand Registration (or, in the case of a Demand
Registration not being underwritten, Softbank), advises the Company in writing
that in its opinion the number of securities requested to be included in such
Demand Registration exceeds the number which can be sold in such offering
without a significant adverse effect on the price, timing or distribution of the
securities offered, the Company will include in such Registration only the
number of securities that, in the opinion of such underwriter or agent (or
Softbank, as the case may be), can be sold without a significant adverse affect
on the price, timing or distribution of the securities offered.

                  The Company and other holders of securities of the Company may
include other securities in such Registration if, but only if, such underwriter
or agent (or Softbank, as the case may be) concludes that such inclusion will
not have a significant adverse effect on the price, timing or distribution of
all the securities requested to be included in such Registration.

                  (c) The Company's Right to Defer Registration. If the Company
                      -----------------------------------------
is requested to effect a Demand Registration and the Company furnishes to
Softbank a copy of a resolution of the Board of Directors certified by the
Secretary of the Company stating that in the good faith judgment of the Board of
Directors it would be adverse to the Company and its

                                      -3-
<PAGE>
 
securityholders for such Registration Statement to be filed on or before the
date such filing would otherwise be required hereunder because such registration
would interfere with any financing, acquisition, corporate reorganization or
other material transaction involving the Company or any of its Subsidiaries or
would require premature disclosure thereof, or would require disclosure of
material information which the Company would be justified in not disclosing in
the absence of such Registration, the Company shall have the right to defer such
filing for a reasonable period not to exceed 90 days after receipt of the
request for such Registration from Softbank. If the Company shall so postpone
the filing of a Registration Statement and if Softbank within 30 days after
receipt of the notice of postponement advises the Company in writing that it has
determined to withdraw its request for Registration, then such Demand
Registration shall be deemed to be withdrawn by it and such request shall be
deemed not to have been exercised for purposes of determining whether Softbank
retains the right to Demand Registrations pursuant to this Section 2.1. In
addition, if Softbank so notifies the Company of its determination to withdraw
its request for Registration and, within the 60 days immediately following the
deferral period, Softbank makes a written request to the Company for
Registration of the same class of Registrable Securities that were subject to
the Registration withdrawn pursuant to the preceding sentence, the Company shall
have no right to defer such Registration pursuant to this paragraph (c).

                  (d) Registration Statement Form. Registrations under this
                      ---------------------------
Section 2.1 shall be on such appropriate registration form of the Commission (i)
as shall be selected by the Company and as shall be reasonably acceptable to
Softbank and (ii) as shall permit the disposition of such Registrable Securities
in accordance with the intended method or methods of disposition specified in
Softbank's request for such Registration. If, in connection with any
Registration under this Section 2.1 which is proposed by the Company to be on
Form S-3 or any successor form to such Form, the managing underwriter, if any,
shall advise the Company in writing that in its opinion the use of another
permitted form is of material importance to the success of the offering, then
such Registration shall be on such other permitted form.

                  (e) Selection of Underwriters. If any offering pursuant to a
                      -------------------------
Demand Registration involves an underwritten offering, Softbank shall have the
right to select the managing underwriter or underwriters to administer the
offering, subject to the consent of the Company, which consent shall not be
unreasonably withheld.

         2.2      Piggyback Registrations.
                  -----------------------

                  (a) Participation. Subject to Section 2.2(b) hereof, if at any
                      -------------
time and from time to time after the date hereof, the Company files a
Registration Statement under the Securities Act with respect to any offering of
any equity securities by the Company for its own account or for the account of
any of its equity holders (other than (i) a registration on Form S-4 or S-8 or
any successor form to such Forms or (ii) any registration of securities as it
relates to an offering and sale to management of the Company pursuant to any
employee stock plan or other employee benefit plan arrangement) then, as soon as
practicable (but in no event less than ten days prior to the proposed date of
filing such Registration Statement), the Company shall give written notice of
such proposed filing to Softbank, and such notice shall offer Softbank the
opportunity to register such number of Registrable Securities as Softbank may
request (a

                                      -4-
<PAGE>
 
"Piggyback Registration") and shall specify whether the offering is to be
underwritten or is to on another basis. Subject to Section 2.2(b), the Company
shall include in such Registration Statement all Registrable Securities
requested within 30 days after the receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by Softbank)
to be included in the Registration for such offering pursuant to a Piggyback
Registration; provided, however, that if, at any time after giving written
notice of its intention to register any securities and prior to the effective
date of the Registration Statement filed in connection with such Registration,
the Company shall determine for any reason not to register or to delay
registration of such securities, the Company may, at its election, give written
notice of such determination to Softbank and, thereupon, (i) in the case of a
determination not to register, shall be relieved of its obligation to register
any Registrable Securities in connection with such Registration (but not from
its obligation to pay the Registration Expenses in connection therewith),
without prejudice, however, to the rights of Softbank to request that such
Registration be effected as a Registration under Section 2.1, and (ii) in the
case of a determination to delay registering, shall be permitted to delay
registering any Registrable Securities, for the same period as the delay in
registering such other securities. If the offering pursuant to such Registration
Statement is to be underwritten, then Softbank must participate in such
underwritten offering and shall not be permitted to make any other offering in
connection with such Registration. If the offering pursuant to such Registration
Statement is to be on any other basis, then, if Softbank makes a request for a
Piggyback Registration pursuant to this Section 2.2(a), it must participate in
such offering on such basis and it shall not be permitted to make an
underwritten offering in connection with such Registration. Softbank shall be
permitted to withdraw all or part of its Registrable Securities from a Piggyback
Registration at any time prior to the effective date thereof.

                  (b) Underwriter's Cutback. The Company shall use its best
                      ---------------------
efforts to cause the managing underwriter or underwriters of a proposed
underwritten offering to permit the Registrable Securities requested to be
included in the Registration for such offering under Section 2.2(a) or pursuant
to other piggyback registration rights granted by the Company, if any
("Piggyback Securities"), to be included on the same terms and conditions as any
similar securities included therein. Notwithstanding the foregoing, if the
managing underwriter or underwriters of any such proposed underwritten offerings
informs the Company and Softbank in writing that the total amount or kind of
securities, including Piggyback Securities, which Softbank and any other persons
or entities intend to include in such offering would be reasonably likely to
adversely affect the price or distribution of the securities offered in such
offering or the timing thereof, then the securities to be included in such
Registration shall be (i) first, 100% of the securities that the Company or
Softbank making a request for a Demand Registration pursuant to Section 2.1 or
pursuant to other demand registration rights, as the case may be, proposes to
sell, subject to the provisions of Section 2.1(b) and (ii) second, the number of
securities that, in the opinion of such underwriter or underwriters, can be sold
without an adverse effect on the price, timing or distribution of the securities
to be included.

                  (c) No Effect on Demand Registrations. No Registration of
                      ---------------------------------
Registrable Securities effected pursuant to a request under this Section 2.2
shall be deemed to have been effected pursuant to Section 2.1 hereof or shall
relieve the Company of its obligation to effect any Registration upon request
under Section 2.1 hereof.

         2.3      Hold-Back Agreements.
                  --------------------

                  (a) Restrictions on Public Sale by Softbank. Softbank agrees,
                      ---------------------------------------
if requested by (i) the Company, or (ii) the managing underwriters in an
underwritten offering, not to effect any public sale or distribution of
securities of the Company the same as or similar to those being registered, or
any securities convertible into or exchangeable or exercisable for such
securities, in any Registration Statement, including a sale pursuant to Rule 144
under the Securities Act (except as part of such underwritten registration),
during the 14-day period prior to, and during the 90-day period (or, with
respect to a Piggyback Registration, such longer period of up to 180 days as may
be required by such underwriter) beginning on, the effective date of any
Registration Statement (except as part of such registration) or the commencement
of the public distribution of securities, to the extent timely notified in
writing by the Company or the managing underwriters (or the holders, as the case
may be).

                  (b) Restrictions on Public Sale by the Company and Others. The
                      -----------------------------------------------------
Company agrees, if requested by the managing underwriter in an underwritten
offering, not to effect any public sale or distribution of any securities the
same as or similar to those being registered by the Company, or any securities
convertible into or exchangeable or exercisable for such securities, during the
14-day period prior to, and during the 90-day period (or, with respect to a
Piggyback Registration, such longer period of up to 180 days as may be required
by the underwriter) beginning on, the effective date of a Registration Statement
filed under Section 2.1 or Section 2.2 hereof or the commencement of the public
distribution of securities to the extent timely notified in writing by Softbank
or the managing underwriters (except as part of such registration, if permitted,
or pursuant to registrations on Forms S-4 or S-8 or any successor form to such
Forms or any registration of securities for offering and sale to management of
the Company pursuant to any employee stock plan or other employee benefit plan
arrangement). The Company agrees to use reasonable efforts to obtain from each
holder of restricted securities of the Company the same as or similar to those
being registered by the Company, or any restricted securities convertible into
or exchangeable or exercisable for any of its securities, an agreement not to
affect any public sale or distribution of such securities (other than securities
purchased in a public offering) during such period, except as part of any such
registration if permitted.

                  (c) Other Registration Rights Agreements. The Company may
                      ------------------------------------
enter into any other registration rights agreement; provided, however, that the
rights and benefits of a securityholder with respect to registration of the
Company's securities as contained in any such other agreement shall be no more
favorable than the rights and benefits of holders of Registrable Securities as
contained in this Agreement.

         2.4 Registration Procedures. In connection with the Company's
             -----------------------
Registration obligations pursuant to Sections 2.1 and 2.2 hereof, the Company
will use its best efforts to effect such registration to permit the sale of such
Registrable Securities in accordance with the intended method or methods of
distribution thereof, and pursuant thereto the Company will as expeditiously as
possible:

                  (a) prepare and, not later than 45 days after receipt of any
request for a Demand Registration, file with the Commission a Registration
Statement or Registration

                                      -6-
<PAGE>
 
Statements relating to the applicable Demand Registration or Piggyback
Registration including all exhibits and financial statements required by the
Commission to be filed therewith, and use its best efforts to cause such
Registration Statement to become effective under the Securities Act; provided,
however, that the Company may discontinue any Registration of its securities
which are not Registrable Securities (and, under the circumstances specified in
Section 2.1(d), may delay and, under the circumstances specified in Section
2.2(a), may delay or discontinue Registration of its securities which are
Registrable Securities) at any time prior to the effective date of the
Registration Statement relating thereto;

                  (b) prepare and file with the Commission such amendments and
post-effective amendments to the Registration Statement as may be requested by
Softbank or as may be necessary to keep the Registration Statement effective for
a period of not less than 270 days (or such shorter period which shall terminate
when all Registrable Securities covered by such Registration Statement have been
sold or withdrawn), or, if such Registration Statement relates to an
underwritten offering, such longer period as in the opinion of counsel for the
underwriters a Prospectus is required by law to be delivered in connection with
sales of Registrable Securities by an underwriter or dealer; cause the
Prospectus to be supplemented by any required Prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 under the Securities Act; and
comply with the provisions of the Securities Act, the Exchange Act, and the
rules and regulations promulgated thereunder with respect to the disposition of
all securities covered by such Registration Statement during the applicable
period in accordance with the intended method or methods of distribution by
Softbank set forth in such Registration Statement or supplement to the
Prospectus;

                  (c) notify Softbank and the managing underwriters, if any, and
(if requested) confirm such advice in writing, as soon as practicable after
notice thereof is received by the Company (i) when the Registration Statement or
any amendment thereto has been filed or becomes effective, the Prospectus or any
amendment or supplement to the Prospectus has been filed, and, to furnish
Softbank and managing underwriters, if any, with copies thereof, (ii) of any
request by the Commission or any other federal or state governmental authority
for amendments or supplements to the Registration Statement or the Prospectus or
for additional information, (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement or any order
preventing or suspending the use of any preliminary Prospectus or Prospectus or
the initiation or threatening of any proceedings for such purposes, (iv) if at
any time the representations and warranties of the Company contemplated by
paragraph (m) below cease to be true and correct and (v) of the receipt by the
Company of any notification with respect to the suspension of the qualification
of the Registrable Securities for offering or sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose;

                  (d) promptly notify Softbank and the managing underwriters, if
any, when the Company becomes aware of the happening of any event as a result of
which the Registration Statement or the Prospectus included in such Registration
Statement (as then in effect) contains any untrue statement of a material fact
or omits to state a material fact necessary to make the statements therein (in
the case of the Prospectus and any preliminary prospectus, in the light of the
circumstances under which they were made) not misleading or, if for any other
reason it shall be necessary during such time period to amend or supplement the
Registration Statement or the

                                      -7-
<PAGE>
 
Prospectus in order to comply with the Securities Act and, in either case as
promptly as practicable thereafter, prepare and file with the Commission, and
furnish without charge to the selling holders and the managing underwriters, if
any, a supplement or amendment to such Registration Statement or Prospectus
which will correct such statement or omission or effect such compliance;

                  (e) make every reasonable effort to prevent the issuance of or
to obtain the withdrawal of any stop order or other order suspending the use of
any preliminary Prospectus or Prospectus or suspending any qualification of the
Registrable Securities;

                  (f) if requested by the managing underwriter or underwriters
or Softbank, promptly incorporate in a Prospectus supplement or post-effective
amendment such information as the managing underwriters and Softbank agree
should be included therein relating to the plan of distribution with respect to
such Registrable Securities, including, without limitation, information with
respect to the number of Registrable Securities being sold to such underwriters,
the purchase price being paid therefor by such underwriters and with respect to
any other terms of the underwritten (or best efforts underwritten) offering of
the Registrable Securities to be sold in such offering; and make all required
filings of such Prospectus supplement or post-effective amendment as soon as
practicable after being notified of the matters to be incorporated in such
Prospectus supplement or post-effective amendment;

                  (g) furnish to Softbank and each managing underwriter, without
charge, one executed copy and as many conformed copies as they may reasonably
request, of the Registration Statement and any amendment or post-effective
amendment thereto, including financial statements and schedules, all documents
incorporated therein by reference and all exhibits (including those incorporated
by reference);

                  (h) deliver to Softbank and the underwriters, if any, without
charge, as many copies of the Prospectus (including each preliminary prospectus)
and any amendment or supplement thereto as such Persons may reasonably request
(it being understood that the Company consents to the use of the Prospectus or
any amendment or supplement thereto by Softbank and the underwriters, if any, in
connection with the offering and sale of the Registrable Securities covered by
the Prospectus or any amendment or supplement thereto) and such other documents
as Softbank may reasonably request in order to facilitate the disposition of the
Registrable Securities by Softbank;

                  (i) on or prior to the date on which the Registration
Statement is declared effective, use its best efforts to register or qualify,
and cooperate with Softbank, the managing underwriter or agent, if any, and
their respective counsel in connection with the registration or qualification of
such Registrable Securities for offer and sale under the securities or blue sky
laws of each state and other jurisdiction of the United States as Softbank, any
such underwriter or agent reasonably requests in writing and do any and all
other acts or things reasonably necessary or advisable to keep such registration
or qualification in effect for so long as such Registration Statement remains in
effect and so as to permit the continuance of sales and dealings therein for as
long as may be necessary to complete the distribution of the Registrable
Securities covered by the Registration Statement; provided that the Company will
not be

                                      -8-
<PAGE>
 
required to qualify generally to do business in any jurisdiction where it is not
then so qualified or to take any action which would subject it to taxation or

<PAGE>
 
                  (r) use its best efforts to comply with all applicable rules
and regulations of the Commission and make generally available to its security
holders, as soon as reasonably practicable (but not more than fifteen months)
after the effective date of the Registration Statement, an earnings statement
satisfying the provisions of Section 11(a) of the Securities Act and the rules
and regulations promulgated thereunder;

                  (s) as promptly as practicable after filing with the
Commission of any

the Prospectus, provide copies of such document to counsel for Softbank and to
the managing underwriters, if any;

                  (t) provide and cause to be maintained a transfer agent and

                  The Company may require Softbank to furnish to the Company
such information regarding distribution of such securities and such other

necessary to enable the Company to comply with the provisions of this Agreement.

                  Softbank agrees by acquisition of such Registrable Securities
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 2.4(d) hereof, Softbank will forthwith
discontinue disposition of Registrable Securities pursuant to such Registration
Statement until Softbank's receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 2.4(d) hereof, or until it is advised in
writing by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings which are incorporated
by reference in the Prospectus, and, if so directed by the Company, such holder
will deliver to the Company (at the Company's expense) all copies, other than
permanent file copies then in such holder's possession, of the Prospectus
covering such Registrable Securities current at the time of receipt of such
notice. In the event the Company shall give any such notice, the time periods
during which such Registration Statement shall be maintained effective
(including the period referred to in Section 2.4(b) hereof) shall be extended by
the number of days during the period from and including the date of the giving
of such notice to and including the date when Softbank either receives the
copies of the supplemented or amended Prospectus contemplated by Section 2.4(d)
hereof or is advised in writing by the Company that the use of the Prospectus
may be resumed.

         2.5      Underwritten Offerings.
                  ----------------------

                  (a) Requested Underwritten Offerings. If requested by the
                      --------------------------------
underwriters for any underwritten offering by Softbank pursuant to a
Registration requested under Section 2.1, the Company will use reasonable
efforts to enter into an underwriting agreement with such underwriters for such
offering, such agreement to be reasonably satisfactory in substance and form to
the Company, Softbank and the underwriters and to contain such representations
and warranties by the Company and such other terms as are generally prevailing
in agreements of that type, including, without limitation, indemnities to the
effect and to the extent provided in Section 2.8. Softbank will cooperate with
the Company in the negotiation of the underwriting agreement and will give
consideration to the reasonable suggestion of the Company regarding the form
thereof. Softbank shall be a party to such underwriting agreement and may, at
its option, require that any or all of the representations and warranties by,
and the other agreements on the part of, the Company to and for the benefit of
such underwriters shall also be made to and for the benefit of Softbank and that
any or all of the conditions precedent to the obligations of such underwriters
under such underwriting agreement be conditions precedent to the obligations of
Softbank. Softbank shall not be required to make any representations or
warranties to or agreements with the Company or the underwriters other than
representations, warranties or agreements regarding such holder, such holder's
Registrable Securities, such holder's intended method of distribution and any
other representations required by law.

                  (b) Incidental Underwritten Offerings. If the Company proposes
                      ---------------------------------
to register any of its securities under the Securities Act as contemplated by
Section 2.2 and such securities are to be distributed by or through one or more
underwriters, the Company will, if requested by Softbank pursuant to Section 2.2
and subject to the provisions of Section 2.2(b), use its best efforts to arrange
for such underwriters to include all the Registrable Securities to be offered
and sold by Softbank among the securities of the Company to be distributed by
such underwriters. Softbank shall be a party to the underwriting agreement
between the Company and such underwriters and may, at its option, require that
any or all of the representations and warranties by, and the other agreements on
the part of, the Company to and for the benefit of such underwriters shall also
be made to and for the benefit of Softbank and that any or all of the conditions
precedent to the obligations of such underwriters under such underwriting
agreement be conditions precedent to the obligations of Softbank. Softbank shall
not be required to make any representations or warranties to or agreements with
the Company or the underwriters other than representations, warranties or
agreements regarding Softbank, Softbank's Registrable Securities and Softbank's
intended method of distribution or any other representations required by law.

                  (c) Participation in Underwritten Registration. No person may
                      ------------------------------------------
participate in any underwritten registration hereunder unless such Person (i)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Persons entitled to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

         2.6 Preparation; Reasonable Investigation. In connection with the
             -------------------------------------
preparation and filing of each Registration Statement, the Company will give
Softbank, its underwriters, if any, and its respective counsel and accountants
the opportunity to participate in the preparation of such Registration
Statement, each Prospectus included therein or filed with Commission, and, to
the extent practicable, each amendment thereof or supplement thereto, and give
each of them such access to its books and records (to the extent customarily
given to underwriters of the Company's securities) and such opportunities to
discuss the business of the Company with its officers and the independent public
accountants who have certified its financial statements as shall be necessary,
in the opinion of Softbank's and such underwriters' respective counsel, to
conduct a reasonable investigation within the meaning of the Securities Act;
provided, however, that any books, records, information or documents that are
designated by the Company in writing as confidential shall be kept confidential
by such Persons unless disclosure thereof is required by law.

         2.7 Registration Expenses. All expenses incident to the Company's
             ---------------------
performance of or compliance with this Agreement, including without limitation
(i) all registration and filing fees, any other fees and expenses associated
with filings required to be made with the Commission or the NASD (including, if
applicable, the fees and expenses of any "qualified independent underwriter" and
its counsel as may be required by the rules and regulations of the NASD), (ii)
all fees and expenses of compliance with state securities or blue sky laws
(including fees and disbursements of counsel for the underwriters or selling
holders in connection with blue sky qualifications of the Registrable Securities
and determination of their eligibility for investment under the laws of such
jurisdictions as the managing underwriters or holders of a majority of the
Registrable Securities being sold may designate), (iii) all printing and related
messenger and delivery expenses (including expenses of printing certificates for
the Registrable Securities in a form eligible for deposit with The Depository
Trust Company and of printing prospectuses), (iv) all fees and disbursements of
counsel for the Company and of all independent certified public accountants of
the Company (including the expenses of any special audit and cold comfort
letters required by or incident to such performance), (v) reasonable premiums
for Securities Act liability insurance if the Company so desires or the
underwriters to reasonably require in accordance with then customary
underwriting practice, (vi) all fees and expenses incurred in connection with
the listing of the Registrable Securities on any securities exchange or
quotation of the Registrable Securities on any inter-dealer quotation system,
(vii) all reasonable fees and disbursements of one counsel selected by Softbank
to represent Softbank in connection with such registration, (viii) all fees and
disbursements of underwriters customarily paid by the issuers or sellers of
securities, excluding underwriting discounts and commissions and transfer taxes,
if any, and excluding fees and disbursements of counsel to such underwriters
(other than such fees and disbursements incurred in connection with any
registration or qualification of Registrable Securities under the securities or
blue sky laws of any state), (ix) all fees and expenses of accountants to
Softbank and (x) fees and expenses of other Persons retained by the Company (all
such expenses being herein called "Registration Expenses"), will be borne by the
Company, regardless of whether the Registration Statement becomes effective
(except as provided in Section 2.1 hereof). The Company will, in any event, pay
its internal expenses (including, without limitation, all salaries and expenses
of its officers and employees performing legal or accounting duties), the
expense of any audit and the fees and expenses of any Person, including special
experts, retained by the Company.

         2.8      Indemnification.
                  ---------------

                  (a) Indemnification by the Company. The Company agrees to
                      ------------------------------
indemnify and hold harmless, to the full extent permitted by law, Softbank, its
officers, directors, employees, partners, shareholders and agents and each
Person who controls Softbank (within the meaning of the Securities Act or the
Exchange Act) from and against all losses, claims, damages, liabilities and
expenses (including reasonable costs of investigation and legal expenses)
arising out of or based upon any untrue or alleged untrue statement of a
material fact contained in any Registration Statement, Prospectus or preliminary
Prospectus or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as the same are caused by or contained in any
information furnished in writing to the Company, by Softbank expressly for use
therein; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage, liability or expense
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any such preliminary Prospectus if (i)
it is determined that it was the responsibility of Softbank to provide the
Person asserting such loss, claim, damage, liability or expense with a current
copy of the Prospectus and Softbank failed to deliver or cause to be delivered a
copy of the Prospectus to such Person after the Company had furnished such
holder with a sufficient number of copies of the same and (ii) the Prospectus
completely corrected in a timely manner such untrue statement or omission. This
indemnity shall be in addition to any liability the Company may otherwise have,
shall remain in full force and effect regardless of any investigation made by or
on behalf of such holder or any such officer, director, employee, agent,
partner, shareholder or controlling Person and shall survive termination of this
Agreement and the transfer of Registrable Securities by Softbank. The Company
will also indemnify underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, their
officers, directors, partners, shareholders and each Person who controls such
Persons (within the meaning of the Securities Act and the Exchange Act) to the
same extent as provided above (with appropriate modification) with respect to
the indemnification of the holders of Registrable Securities, if requested.

                  (b) Indemnification by Softbank. Softbank agrees to indemnify
                      ---------------------------
and hold harmless, to the full extent permitted by law, the Company, its
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act or the Exchange Act) from and against any losses,
claims, damages, liabilities and expenses resulting from any untrue statement of
a material fact or any omission of a material fact required to be stated in the
Registration Statement, Prospectus or preliminary Prospectus or necessary to
make the statements therein not misleading, to the extent, but only to the
extent, that such untrue statement or omission is caused by or contained in any
information furnished in writing by Softbank to the Company specifically for
inclusion in such Registration Statement or Prospectus and has not been
corrected in a subsequent writing prior to or concurrently with the sale of the
Registrable Securities to the Person asserting such loss, claim, damage,
liability or expense. This indemnity shall be in addition to any liability such
selling holder may otherwise have, shall remain in full force and effect
regardless of any investigation made by or on behalf of the Company or any such
officer, director or controlling Person and shall survive termination of this
Agreement and the transfer of Registrable Securities by Softbank. The Company
shall be entitled to receive

                                     -13-
<PAGE>
 
indemnities from underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the same
extent as provided above (with appropriate modification) with respect to
information so furnished in writing by such Persons specifically for inclusion
in any Prospectus or Registration Statement.

                  (c) Conduct of Indemnification Proceedings. Any Person
                      --------------------------------------
entitled to indemnification hereunder will (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks indemnification
and (ii) permit such indemnifying party to assume the defense of such claim with
counsel reasonably satisfactory to the indemnified party; provided, however,
that any delay or failure to so notify the indemnifying party shall relieve the
indemnifying party of its obligations hereunder only to the extent, if at all,
that it is prejudiced by reason of such delay or failure; provided further,
however, that any Person entitled to indemnification hereunder shall have the
right to select and employ separate counsel and to participate in the defense of
such claim, but the fees and expenses of such counsel shall be at the expense of
such Person unless (i) the indemnifying party has agreed in writing to pay such
fees or expenses, or (ii) the indemnifying party shall have failed to assume the
defense of such claim within a reasonable time after receipt of notice of such
claim from the Person entitled to indemnification hereunder and employ counsel
reasonably satisfactory to such Person, or (iii) in the reasonable judgment of
any such Person, based upon advice of its counsel, a conflict of interest may
exist between such Person and the indemnifying party with respect to such claims
(in which case, if the Person notifies the indemnifying party in writing that
such Person elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of
such claim on behalf of such Person). If such defense is not assumed by the
indemnifying party, the indemnifying party will not be subject to any liability
for any settlement made without its consent (but such consent will not be
unreasonably withheld), provided that an indemnifying party shall not be
required to consent to any settlement involving the imposition of equitable
remedies or involving the imposition of any material obligations on such
indemnifying party other than financial obligations for which such indemnified
party will be indemnified hereunder. No indemnifying party shall consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation. Whenever the indemnified party or the indemnifying party receives a
firm offer to settle a claim for which indemnification is sought hereunder, it
shall promptly notify the other of such offer. If the indemnifying party refuses
to accept such offer within 20 business days after receipt of such offer (or of
notice thereof), such claim shall continue to be contested and, if such claim is
within the scope of the indemnifying party's indemnity contained herein, the
indemnified party shall be indemnified pursuant to the terms hereof. If the
indemnifying party notifies the indemnified party in writing that the
indemnifying party desires to accept such offer, but the indemnified party
refuses to accept such offer within 20 business days after receipt of such
notice, the indemnified party may continue to contest such claim and, in such
event, the total maximum liability of the indemnifying party to indemnify or
otherwise reimburse the indemnified party hereunder with respect to such claim
shall be limited to and shall not exceed the amount of such offer, plus
reasonable out-of-pocket costs and expenses (including reasonable attorneys'
fees and disbursement) to the date of notice that the indemnifying party desires
to accept such offer, provided that this sentence shall not apply to any
settlement of any claim involving the imposition of equitable remedies or to any



                                     -14-
<PAGE>
 
settlement imposing any material obligations on such indemnified party other
than financial obligations for which such indemnified party will be indemnified
hereunder. An indemnifying party who is not entitled to, or elects not to,
assume the defense of a claim will not be obligated to pay the fees and expenses
of more than one counsel for all parties indemnified by such indemnifying party
who is not entitled to, or elects not to, assume the defense of a claim will not
be obligated to pay the fees and expenses of more than one counsel for all
parties indemnified by such indemnifying party with respect to such claim,
unless in the written opinion of counsel to the indemnified party reasonably
satisfactory to the indemnifying party, use of one counsel by the underwriters
on the one hand, and by the securityholders on the other, would be expected to
give rise to a conflict of interest between such underwriters, on the one hand
and such securityholders on the other with respect to such claim, in which event
the indemnifying party shall be obligated to pay the fees and expenses of one
such additional counsel.

                  (d) Contribution. If for any reason the indemnification
                      ------------
provided for in the preceding paragraphs (a) and (b) is unavailable to an
indemnified party or insufficient to hold it harmless as contemplated by the
preceding paragraphs (a) and (b), then the indemnifying party shall contribute
to the amount paid or payable by the indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect not
only the relative benefits received by the indemnified party and the
indemnifying party, but also the relative fault of the indemnified party and the
indemnifying party, as well as any other relevant equitable considerations,
provided that Softbank shall not be required to contribute in an amount greater
than the dollar amount of the proceeds received by Softbank with respect to the
sale of any such Registrable Securities. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

         2.9 Rules 144 and 144A. The Company covenants that it will file the
             ------------------
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the Commission thereunder (or, if the
Company is not required to file such reports, it will, upon the request of
Softbank after the date that is the second anniversary of the date thereof, make
publicly available other information so long as necessary to permit sales
pursuant to Rule 144 or 144A under the Securities Act), and it will take such
further action as Softbank may reasonably request, all to the extent required
from time to time to enable Softbank to sell Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by (i) Rules 144 or 144A under the Securities Act, as such Rules may be
amended from time to time, or (ii) any similar rule or regulation hereafter
adopted by the Commission. Upon the request of any holder of Registrable
Securities, the Company will deliver to such holder a written statement as to
whether it has complied with such requirements.

3.       Transfer of Securities.
         ----------------------

         3.1 Notice of Proposed Transfer. At the time of any transfer or sale or
             ---------------------------
proposed transfer or sale of any Softbank Securities, the Company may require
written notice describing briefly the manner of such transfer or sale and a
written opinion of counsel for the holder thereof (who may be inside counsel) to
the effect that such transfer or sale may be effected without the registration
of Softbank Securities under the Securities Act and will be made in compliance
with

                                     -15-
<PAGE>
 
applicable state securities and blue sky laws. The Company shall thereupon
permit or cause its transfer agent (if any) to permit such transfer or sale to
be effected unless the Company, within five days after receipt of such notice
and opinion, shall furnish to such holder and such holder's counsel (if any) an
opinion of the Company's outside counsel which (i) states that such sale or
transfer may not be effected without the registration of such Softbank
Securities under the Securities Act (or will not be made in compliance with
applicable securities and blue sky laws) and (ii) specifies the reasons,
factual, legal or both, why such counsel's opinion differs from that of holder's
counsel. However, if in such written notice to the Company the transferring
holder informs the Company that the transfer or sale is to a purchaser or
transferee whom the transferring holder knows or reasonably believes to be a
"qualified institutional buyer," as that term is defined in Rule 144A
promulgated under the Securities Act, no opinion of counsel shall be required.

         3.2 Termination of Restrictions. Notwithstanding the foregoing
provisions of this Section 3, the restrictions imposed by this Section 3 upon
the transferability of the Softbank Securities shall terminate as to any
particular Softbank Securities when (i) such Softbank Securities shall have been
effectively registered under the Securities Act and sold by the holder thereof
in accordance with such registration, (ii) such Softbank Securities have been
sold in accordance with Rule 144 or 144A promulgated under the Securities Act,
or (iii) written opinions to the effect that such restrictions are no longer
required or necessary under any federal or state law or regulation have been
received from counsel for the holder of thereof (who may be inside counsel) and,
if the Company shall so require, from counsel for the Company.

         3.3 Exchange, Transfer and Replacement of Certificates. Subject to the
foregoing provisions of this Section 3, upon surrender of any certificate
representing Softbank Securities duly endorsed for exchange or transfer, the
Company will, at its expense, or will cause its transfer agent, at the Company's
expense, to issue in exchange therefor new certificates in such denominations as
may be requested by the certificate so surrendered and registered as such
stockholder may request. Upon receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of any certificate
representing Softbank Securities and, in the case of any such loss, theft or
destruction, upon delivery of an agreement of indemnity satisfactory to the
Company, or, in the case of any such mutilation, upon surrender and cancellation
of such certificate, the Company will issue, at its expense, or will cause its
transfer agent, at the Company's expense, to issue a new certificate
representing the same aggregate number of Softbank Securities represented by
such lost, stolen, destroyed or mutilated certificate; provided, however, that
in the event of any loss, theft or destruction of any certificate representing
Softbank Securities registered in the name of Softbank or any of its Affiliates,
or in the name of any other holder which is an institutional investor or its
nominee, the Company shall not require such person or Affiliate or any other
holder which is an institutional investor or its nominee to furnish any
indemnity or surety bond in connection with the issuance of a new certificate
therefor if the Company is furnished with an affidavit of the holder (if the
holder is an individual) or, otherwise, the Chairman of the Board, President,
any Vice President, Treasurer or any Assistant Treasurer of the holder (or, in
the case of a nominee, the beneficial owner for which such holder is serving as
nominee) setting forth the fact of such loss, theft or destruction and, together
with such affidavit, such holder furnishes (or, in case of a nominee, the
beneficial owner for which such holder is serving as nominee furnishes) to the
Company its written



                                     -16-
<PAGE>
 
agreement to indemnify the Company with respect to such loss, theft or
destruction; the Company shall, however, have the right to require any holder of
Softbank Securities other than Softbank or any of its Affiliates or any other
holder which is an institutional investor or its nominee to furnish such an
indemnity or surety bond. The party delivering any certificate representing
Softbank Securities pursuant to this Section 3.3 will pay the cost of such
delivery (including the cost of insurance against loss or theft in an amount
satisfactory to the sender).

4.       Miscellaneous.
         -------------

         4.1 Injunctive Relief. Remedies for breach by the Company of its
             -----------------
obligations to register the Registrable Securities shall be as otherwise set
forth herein. It is hereby agreed and acknowledged that it will be impossible to
measure in money the damages that would be suffered if the parties fail to
comply with any of the obligations herein imposed on them and that in the event
of any such failure, an aggrieved Person will be irreparably damaged and will
not have an adequate remedy at law. Any such Person shall, therefore, be
entitled to injunctive relief, including specific performance, to enforce such
obligations, and if any action should be brought in equity to enforce any of the
provisions of this Agreement, none of the parties hereto shall raise the defense
that there is an adequate remedy at law.

         4.2 Notices. All notices, other communications or documents provided
             -------
for or permitted to be given hereunder, shall be made in writing and shall be
given either personally by hand-delivery, by facsimile transmission, by mailing
the same in a sealed envelope, registered first-class mail, postage prepaid,
return receipt requested, or by air courier guaranteeing overnight delivery:

                           Dated as of March 27, 1996

                As Amended and Restated as of February 26, 1998

     SOFTBANK HOLDINGS INC., a Delaware corporation, each of the Guarantors and

                                   ARTICLE 1
                                   ---------

     Section 1.01  Commitment to Lend.
                   ------------------ 

          (a)   RC Loans.
                -------- 

          Upon the terms and subject to the conditions of this Agreement, each
Bank agrees to make, from time to time during the period from the Restated
Agreement Date through the Termination Date, one or more RC Loans to the
Borrower in an aggregate unpaid principal amount not exceeding at any time such
Bank's Commitment at such time; provided that no RC Loan shall be made if, after
                                --------                                        
giving effect to the making of such Loan and the simultaneous application of the
proceeds thereof, (i) the Exposure of such Bank would exceed the Commitment of
such Bank or (ii) the aggregate amount of the Exposures of all of the Banks
would exceed the aggregate amount of the Commitments.  The aggregate amount of
the Commitments on the Restated Agreement Date is $250,000,000.  Subject to

the making of such Loan and the simultaneous application of the proceeds thereof
(i) the aggregate principal amount of outstanding Swing Loans would exceed the
Swing Line Sublimit or (ii) the aggregate amount of the Exposures of all of the
Banks would exceed the aggregate amount of the Commitments.  Swing Loans may
only be made and continued as Base Rate Loans or Agreed Rate Loans.  The Swing
Line Sublimit is $25,000,000.


     Section 1.02  Manner of Borrowing.
                   ------------------- 


          (a)  RC Loans.
               -------- 

          With respect to RC Loans:


     (i)  The Borrower shall give the Agent notice (which shall be irrevocable)
no later than, in the case of a Base Rate Loan, 10:00 a.m. on the requested date
for the making of such Loan and, in the case of a Eurodollar Rate Loan, 11:00
a.m. on the third Eurodollar 
<PAGE>
 
Business Day before the requested date for the making of such Loan. Each such
notice shall be in the form of Schedule 1.02(a) and shall specify (A) the 
                               ----------------
requested date for the making of the requested Loan, which shall be, in the case
of a Base Rate Loan, a Business Day and, in the case of a Eurodollar Rate Loan,
a Eurodollar Business Day, (B) the Type or Types of Loans requested and (C) the
amount of each such Type of Loan, the aggregate of which amounts for all Types
of Loans requested shall be not less than (1) in the case of Eurodollar Rate
Loans $5,000,000 or any integral multiple of $5,000,000 in excess thereof and
(2) in the case of Base Rate Loans the lesser of $1,000,000 or any integral
multiple of $1,000,000 in excess thereof, and the aggregate amount of the unused
Commitments. Upon receipt of any such notice, the Agent shall promptly notify
each Bank of the contents thereof and the amount and Type of Loan to be made by
such Bank. Each Loan so requested shall be disbursed by the Agent not later than
2:00 p.m. on the requested date therefor in Dollars in funds immediately
available to the Borrower by credit to an account of the Borrower at the Agent's
Office or in such other manner as may have been specified in the applicable
notice and as shall be acceptable to the Agent.



   (ii)  On each requested date for the making of RC Loans, each Bank shall, if
it has received the notice contemplated by Section 1.02(a)(i) on or prior to (A)
in the case of Eurodollar Rate Loans, its close of business on the third
Eurodollar Business Day before such requested date and (B) in the case of Base
Rate Loans, 11:00 a.m. on such requested date, make available to the Agent, not
later than (x) in the case of Eurodollar Rate Loans, 11:00 a.m. and (y) in the
case of Base Rate Loans, 1:00 p.m., in Dollars in funds immediately available to
the Agent at the Agent's Office, the RC Loans to be made by such Bank on such
requested date.  Any Bank's failure to make any RC Loan to be made by it on the
requested date therefor shall not relieve any other Bank of its obligation to
make any Loan to be made by such other Bank on such date, but such other Bank
shall not be liable for such failure.

               

   (iii)  Unless the Agent shall have received notice from a Bank prior to (A)
in the case of Eurodollar Rate Loans, 10:00 a.m., and (B) in the case of Base
Rate Loans, 12:00 noon, on the requested date for the making of any RC Loans
that such Bank will not make available to the Agent the RC Loans requested to be
made by such Bank on such date, the Agent may assume that such Bank has made
such RC Loans available to the Agent on such date in accordance with Section
1.02(a)(ii) and the Agent in its sole discretion may, in reliance upon such
assumption, make available to the Borrower (or, in the case of RC Loans
requested pursuant to Section 1.04(b) or Section 1.05(c)(i), to the Swing Line
Bank) on such date a corresponding amount on behalf of such Bank. If and to the
extent such Bank shall not have so made available to the Agent the RC Loans
requested to be made by such Bank on such date and the Agent shall have so made
available to the Borrower a corresponding amount on behalf of such Bank, such
Bank shall, on demand, pay to the Agent such corresponding amount together with
interest thereon, for each day from the date such amount shall have been so made
available by the Agent to the Borrower until the date such amount shall have
been repaid to the Agent, at the Federal Funds Rate until (and including) the
third Business Day after demand is made and thereafter at the Base Rate. If such
Bank does not pay such corresponding amount promptly upon the Agent's demand
therefor, the Agent shall promptly notify the Borrower and the Borrower shall
immediately repay such corresponding amount to the Agent together with accrued
interest thereon at the applicable rate or rates provided in Section 1.03(a).

          With respect to Swing Loans:

               

     (i) The Borrower shall give the Agent and, if the Swing Line Bank is a Bank
that is not the Agent, the Swing Line Bank notice (which shall be irrevocable)
no later than 1:00 p.m. on the requested date for the making of a Swing Loan.
Each such notice shall specify (A) the amount of the requested Swing Loan, which
amount shall be not less than the lesser of (1) $100,000 or any integral
multiple of $100,000 in excess thereof and (2) the Swing Line Availability on
the requested date for the making of such Swing Loan, (B) whether such Swing
Loan shall be an Agreed Rate Loan or a Base Rate Loan and (C) if such Swing Loan
shall be an Agreed Rate Loan, the number of days (which shall not be more than
five Business Days) that the Agreed Rate for such Swing Loan is to obtain (the
"Agreed Rate Interest Period").  Such notice may be by telephone, confirmed by
telecopy on the date of the making of the requested Swing Loan.  If the Borrower
and the Swing Line Bank do not agree upon a requested Agreed Rate, the requested
Swing Loan shall be made as a Base Rate Loan, unless the Borrower withdraws the
request for such Swing Loan.  Upon the expiration of an Agreed Rate Interest
Period, the Swing Loan in question shall be continued, subject to Section
1.04(b), as a Base Rate Loan.

                   

   (ii)  Swing Loans shall be disbursed by the Swing Line Bank not later than
4:30 p.m. on the requested date therefor in Dollars in funds immediately

thereof at a rate per annum equal to the Base Rate as in effect from time to
time plus the applicable Base Rate Margin or, if the Borrower and the Swing Line
Bank shall have agreed upon an Agreed Rate with respect to such Swing Loan, such
Agreed Rate; provided that upon the earliest of (A) the fifth Business Day after
             --------

interest at the Agreed Rate and shall bear interest at the Base Rate as in
effect from time to time plus the applicable Base Rate Margin.

               (iii)  Post-Default Rate.
                      ----------------- 

         During an Event of Default (which is such by virtue of clause (a) of
Section 6.01 and whether before or after judgment), each Loan (whether or not
due) and, to the maximum extent permitted by Applicable Law, all other amounts
of interest and fees due and payable under the Borrower Loan Documents, shall
bear interest at a rate per annum equal to the applicable Post-Default Rate.

          (b)  Payment.
               ------- 

          Interest shall be payable, (i) in the case of Base Rate Loans that are
RC Loans, on each Interest Payment Date, (ii) in the case of Eurodollar Rate
Loans, on the 

                                       3

last day of each applicable Interest Period (and, if an Interest Period is
longer than three months, at intervals of three months after the first day of
such Interest Period) and (iii) in the case of any Loan, when such Loan shall be
due (whether at maturity, by reason of notice of prepayment or acceleration or
otherwise) or converted, but only to the extent then accrued on the amount then
so due or converted. Interest at the Post-Default Rate shall be payable on
demand.

          (c)  Conversion and Continuation.
               ---------------------------

   (ii)  Each RC Loan that is a Base Rate Loan shall continue as a Base Rate
Loan unless and until such Loan is converted into an RC Loan of another Type.
Each RC Loan that is a Eurodollar Rate Loan of any Type shall continue as a Loan
of such Type until the end of the then current Interest Period therefor, at
which time it shall be automatically converted into a Base Rate Loan unless the
Borrower shall have given the Agent notice in accordance with Section 1.03(c)
requesting either that such Loan continue as a Loan of such Type for another
Interest Period or that such Loan be converted into a Loan of another Type at
the end of such Interest Period.

                      

  (iii)  Notwithstanding anything to the contrary contained in Section
1.03(c)(i) or (ii), during a Default, the Agent may notify the Borrower that RC
Loans may only be converted into or continued as RC Loans of certain specified
Types and, thereafter, until no Default shall continue to exist, RC Loans may
not be converted into or continued as RC Loans of any Type other than one or
more of such specified Types.

                     

  (iv)   The Borrower shall give the Agent notice (which shall be irrevocable)
of each conversion of an RC Loan or continuation of an RC Loan that is a
Eurodollar Rate Loan no later than, in the case of a conversion into a Base Rate
Loan, 12:00 noon on the Business Day, and, in the case of a conversion into or
continuation of an RC Loan that is a Eurodollar Rate Loan, 11:00 a.m. on the

or continuation, (B) the amount and Type and, in the case of Eurodollar Rate
Loans, the last day of the applicable Interest Period of each Loan to be
converted or continued and (C) the amount and Type or Types of Loans into which
such Loans are to be converted.  Upon receipt of any such notice, the Agent
shall promptly notify each Bank of (x) the contents thereof, (y) the amount and
Type and, in the case of Eurodollar Rate Loans, the last day of the applicable
Interest Period of each Loan to be converted or continued by such Bank and (z)
the amount and Type or Types of Loans into which such Loans are to be converted
or as which such Loans are to be continued.

any asset of the Borrower or any Guarantor (other than dispositions to which
Section 4.10 is not applicable) the Commitments shall be reduced in an amount

the Commitments as so reduced. The Commitments shall be reduced and any Loans to
be prepaid shall be prepaid at the time or times that Net Cash Proceeds from
such disposition are paid.

          (c) Default Mandatory Prepayments and Fundings.
              ------------------------------------------ 

                (i)   Default Mandatory Prepayments of Swing Loans.
                      -------------------------------------------- 

         If any Default other than a Bankruptcy Default exists, the Swing Line
Bank may request that outstanding Swing Loans be refunded by delivering to the
Agent and the Borrower on a Business Day a request to that effect, specifying
the principal amount of outstanding Swing Loans.  Such a request shall (A) be
deemed to constitute a notice under Section 1.02(a) requesting RC Loans in an
amount equal to the outstanding Swing Loans be made by the Banks (including the
Swing Line Bank) and that such Loans be Base Rate Loans, (B) have the same force
and effect as a notice from the Borrower under such Section and (C) be subject
to all the terms and conditions of Section 1.02(a), except that (1) the
requirement (aa) to deliver a notice in the form of Schedule 1.02(a) and (bb)
                                                    ----------------         
that the aggregate amount of Loans be not less than the amount specified in
Section 1.02(a) for the applicable Type of Loan shall not apply and (2) the
conditions to borrowing specified in Section 2.02 (other than that a Bankruptcy
Default shall not exist) shall not apply.

               (ii) Default Mandatory Fundings of Participations in Swing Loans.
                    ----------------------------------------------------------- 

(A)   During a Bankruptcy Default, upon request (which shall relate to all Swing
Loans then outstanding) by the Swing Line Bank on a Business Day, each Bank
shall purchase from the Swing Line Bank, without recourse or warranty (except
that such outstanding Swing Loans in fact were made in accordance with Section
1.01(b)(i), and are not subject to any Liens arising out of any act of the Swing
Line Bank), a participation in the Swing Loans then outstanding by paying to the
Swing Line Bank, in Dollars immediately available to the Swing Line Bank at the
Swing Line Bank's Office, an amount equal to such Bank's Pro Rata Share of the
principal amount of such Swing Loans, with such payment being due on the day
such request is made, if such request is made prior to 2:00 p.m. on such day, or
if such request is made after 2:00 p.m. on the next Business Day (the
"Participation Payment Date").  Such participation shall constitute an undivided
interest and participation in the principal amount of Swing Loans then
outstanding and in interest that accrues thereon after the Participation Payment
Date.  The Swing Line Bank shall, upon the request of a Bank, furnish to such
Bank a participation certificate evidencing any participation purchased by such
Bank pursuant to this Section 1.05.  If any Bank does not pay any amount which
it is required to pay to the Swing Line Bank pursuant to this Section
1.05(c)(ii)(A) when due, the Swing Line Bank shall be entitled to recover such
amount from such Bank, together with interest thereon for each day from the
Participation Payment Date until the date such amount shall be paid to the Swing
Line Bank, at the Federal Funds Rate until (and including) the third Business
Day after the Participation Payment Date and thereafter at the Base Rate.

          (B) Whenever, at any time after the Swing Line Bank has received from
any Bank payment in accordance with Section 1.05(c)(ii)(A) for its participation
in a Swing Loan, the Swing Line Bank receives any payment attributable to the
principal of, or interest accrued after the Participation Payment Date on, such
Swing Loan, the Swing Line Bank will promptly distribute to such Bank its share
thereof; provided, that in the event that any such payment received by the Swing
         --------                                                               
Line Bank shall be required to be returned by the Swing Line Bank, for any
reason, such Bank shall return to the Swing Line Bank the portion thereof
previously distributed by the Swing Line Bank to it, but without interest
(unless the Swing Line Bank is required to pay interest on the amount so
returned, in which case such Bank shall be required to pay interest at a like
rate).  Payments received after the Participation Payment Date 

                                       6
<PAGE>
 
by the Swing Line Bank on account of Swing Line Loans shall be applied first to
the payment of interest accrued thereon prior to the Participation Payment Date.

               (iii)  Obligations of Banks Absolute and Unconditional.
                      ----------------------------------------------- 

          The obligation of each Bank to make an RC Loan to repay Swing Loans as
contemplated by Section 1.05(c)(i) and to purchase and fund its participation in
Swing Loans as contemplated by Section 1.05(c)(ii) shall be absolute and
unconditional.

          (d) Capital Securities Transfer Mandatory Prepayment.
              ------------------------------------------------ 

          In the event that the Borrower transfers any Capital Securities to ZD
Inc. in a transaction to which Section 4.14 is not applicable by virtue of
clause (d) of such Section, the Commitments shall be reduced in an amount equal
to the Net Cash Proceeds of the public offering referred to in such clause (d)
and the Borrower shall prepay the principal amount of the Loans that is in
excess of the aggregate amount of the Commitments as so reduced.  Such amounts
shall be prepaid and the Commitments shall be reduced at the time or times that
Net Cash Proceeds from such public offering are paid to the Person entitled
thereto.

          (e)  Application to Types of Loans.
               ----------------------------- 

          Amounts prepaid pursuant to Section 1.05(b) shall be applied to
prepay, first, Swing Loans, second, RC Loans that are Base Rate Loans and,
        -----               ------                                        
third, RC Loans that are Eurodollar Rate Loans in the order that the Agreed Rate

Interest Period or Interest Periods, as applicable, for such Loans ends.
Amounts to be prepaid pursuant to Section 1.05(b) shall be paid on the day or
within the time period specified therefor, whether or not such payment would
require a prepayment of Eurodollar Rate Loans prior to the last day of an
applicable Interest Period or would result in losses, costs or expenses
compensable under Section 7.04.

     Section 1.06  Limitation on Types of  Loans.
                   ----------------------------- 

     Notwithstanding anything to the contrary contained in this Agreement, the
Borrower shall borrow, prepay, convert and continue RC Loans in a manner such
that (a) the aggregate principal amount of Eurodollar Rate Loans of the same
Type and having the same Interest Period shall at all times be not less than
$5,000,000, (b) there shall not be, at any one time, more than six Interest
Periods in effect with respect to Eurodollar Rate Loans of all Types and (c) no
payment of a Eurodollar Rate Loan will have to be made prior to the last day of
an applicable Interest Period in order to repay the Loans on (subject to Section
1.11(c)) the Termination Date.

     Section 1.07  Reduction of Commitments.
                   ------------------------ 

     The Borrower may reduce the Commitments by giving the Agent notice (which
shall be irrevocable) thereof no later than 10:00 a.m. on the third Business Day
before the requested date of such reduction, except that no partial reduction of
the Commitments shall be in an aggregate amount less than $10,000,000 or any
integral multiple of $500,000 in excess thereof.  Upon receipt of any such
notice, the Agent shall promptly notify each Bank of the contents thereof and
the amount to which such Bank's Commitment is to be reduced.

     Section 1.08  Commitment Fees.
                   --------------- 

     The Borrower shall pay to the Agent for the account of each Bank a
commitment fee on the daily amount by which such Bank's Commitment exceeds the
aggregate principal amount of its RC Loans for each day from the Restated
Agreement Date through the Termination Date at a rate per annum of (a) on or
prior to May 15, 

                                       7
<PAGE>
 
1998, 0.200%, (b) on or after May 16, 1998, and on or before June 15, 1998,
0.250% and (c) thereafter, 0.375%, payable on successive Interest Payment Dates,
on the Termination Date and on the date of any reduction of such Commitments (to
the extent accrued and unpaid on the amount of such reduction).

     Section 1.09  Computation of Interest and Fees.
                   -------------------------------- 

     Interest on Eurodollar Rate Loans shall be computed on the basis of a year
of 360 days and paid for the actual number of days elapsed.  Interest on Base
Rate Loans and, unless otherwise agreed by the Borrower and the Agent, Agreed
Rate Loans and the commitment fee shall be computed on the basis of a year of
365 or 366 days, as applicable, and paid for the actual number of days elapsed.
Interest for any period shall be calculated from and including the first day
thereof to but excluding the last day thereof.

     Section 1.10  Evidence of Indebtedness.
                   ------------------------ 

     Each Bank's Loans (including the Swing Line Bank) and the Borrower's
obligation to repay such Loans with interest in accordance with the terms of
this Agreement shall be evidenced by this Agreement, the records of such Bank
and, in the case of RC Loans, a single RC Note payable to the order of such Bank
and, in the case of Swing Loans, a Swing Loan Note payable to the order of the
Swing Line Bank.  The records of each Bank shall be prima facie evidence of such
Bank's Loans and accrued interest thereon and of all payments made in respect
thereof.

     Section 1.11  Payments by the Borrower.
                   ------------------------ 

          (a)  Time, Place and Manner.
               ---------------------- 

          All payments due to the Agent under the Borrower Loan Documents shall
be made to the Agent  at the Agent's Office or at such other address as the
Agent may designate by notice to the Borrower.  All payments due to any Bank
under the Borrower Loan Documents shall, in the case of payments by the Borrower
on account of principal of or interest on the Loans (including Swing Loans, so
long as the Bank that is the Swing Line Bank is also the Agent) or fees be made
to the Agent at the Agent's Office and in the case of all other payments
(including payments of principal of, and interest on, Swing Loans, if the Bank
that is the Swing Line Bank is not the Agent), be made directly to such Bank at
its Domestic Lending Office or such other address as the Bank may designate. All
payments due to any Bank under the Borrower Loan Documents, whether made to the
Agent or directly to such Bank, shall be made for the account of, in the case of
payments in respect of Eurodollar Rate Loans, such Bank's Eurodollar Lending
Office and, in the case of all other payments, such Bank's Domestic Lending
Office.  A payment shall not be deemed to have been made on any day unless such
payment has been received by the required Person, at the required place of
payment, in Dollars in funds immediately available to the Agent at such place,
no later than 12:00 noon on such day.

          (b)  No Reductions.
               ------------- 

          All payments due to the Agent or any Bank under the Borrower Loan
Documents, and all other terms, conditions, covenants and agreements to be
observed and performed by the Borrower thereunder, and all payments due to the
Swing Line Bank by a Bank, shall be made, observed or performed by the Borrower
or such Bank, as the case may be, without any reduction or deduction whatsoever,
including any reduction or deduction for any set-off, recoupment, counterclaim
(whether sounding in tort, contract or otherwise) or Tax, except in the case of
payments by the Borrower, subject to Section 1.13, for any withholding or
deduction for Taxes required to be withheld or deducted under Applicable Law;
provided that no payment by any Person to another Person shall constitute a
waiver or 

                                       8
<PAGE>
 
release by the Person making such payment of any right it may have against the
Person receiving such payment.

          (c)  Extension of Payment Dates.
               -------------------------- 

          Whenever any payment to the Agent or any Bank under the Borrower Loan
Documents would otherwise be due (except by reason of acceleration) on a day
that is not a Business Day, or, in the case of payments of the principal of
Eurodollar Rate Loans, a Eurodollar Business Day, such payment shall instead be
due on the next succeeding Business or Eurodollar Business Day, as the case may
be, unless, in the case of a payment of the principal of a Eurodollar Rate Loan,
such extension would cause payment to be due in the next succeeding calendar
month, in which case such due date shall be advanced to the next preceding
Eurodollar Business Day.  If the date any payment under the Borrower Loan
Documents is due is extended (whether by operation of any Borrower Loan
Document, Applicable Law or otherwise), such payment shall bear interest for
such extended time at the rate of interest applicable hereunder.

     Section 1.12  Distribution of Payments by the Agent.
                   ------------------------------------- 

             

   (a)    The Agent shall promptly distribute to each Bank its ratable share of
each payment received by the Agent under the Loan Documents for the account of
the Banks by credit to an account of such Bank at the Agent's Office or by wire
transfer to an account of such Bank at an office of any other commercial bank
located in the United States.

             

   (b)    Unless the Agent shall have received notice from the applicable Loan
Party prior to the date on which any payment is due to the Banks under the Loan
Documents that such Loan Party will not make such payment in full, the Agent may
assume that such Loan Party has made such payment in full to the Agent on such
date and the Agent in its sole discretion may, in reliance upon such assumption,
cause to be distributed to each Bank on such due date a corresponding amount
with respect to the amount then due such Bank.  If and to the extent such Loan
Party shall not have so made such payment in full to the Agent and the Agent
shall have so distributed to any Bank a corresponding amount, such Bank shall,
on demand, repay to the Agent the amount so distributed together with interest
thereon, for each day from the date such amount is distributed to such Bank
until the date such Bank repays such amount to the Agent, at the Federal Funds
Rate until (and including) the third Business Day after demand is made and
thereafter at the Base Rate.

                   ----- 

          (a)  Taxes Payable by the Borrower.
               ----------------------------- 

          If under Applicable Law any Tax is required to be withheld or deducted
from, or is otherwise payable by the Borrower in connection with, any payment to
the Agent or any Bank under the Loan Documents, the Borrower (A) shall (1), if
so required, withhold or deduct the amount of such Tax from such payment and, in
any case, pay such Tax to the appropriate taxing authority in accordance with
Applicable Law and (2) indemnify the Agent or such Bank in accordance with the
provisions of Section 10.02(a) against its failure so to do and (B) shall pay to
the Agent or such Bank such additional amounts as may be necessary so that the
net amount received by the Agent or such Bank with respect to such payment,
after withholding or deducting all Taxes required to be withheld or deducted, is
equal to the full amount payable under the Loan Documents less any Bank Taxes
required to be withheld or deducted, or otherwise payable by the Borrower.  If
any Tax is withheld or deducted from, or is otherwise payable by the Borrower in
connection with, any payment payable to any Bank under the Loan Documents, the
Borrower shall, as soon as 

                                       9
<PAGE>
 
possible after the date of such payment, furnish to the Agent or such Bank the
original or a certified copy of a receipt for such Tax from the applicable
taxing authority. If any payment due to the Agent or any Bank under the Loan
Documents is or is expected to be made without withholding or deducting
therefrom, or otherwise paying in connection therewith, any Tax payable to any
taxing authority, the Borrower shall, within 30 days after any request from the
Agent, furnish to the Agent a certificate from such taxing authority, or an
opinion of counsel acceptable to the Agent, in either case stating that no Tax
payable to such taxing authority was or is, as the case may be, required to be
withheld or deducted from, or otherwise paid by the Borrower in connection with,
such payment.

          (b) Taxes Payable by the Agent or any Bank.
              -------------------------------------- 

          The Borrower shall, promptly upon request by the Agent or any Bank for
the payment thereof, pay to the Agent or such Bank (A) all Taxes (other than
Bank Taxes) payable by the Agent or such Bank with respect to any payment due to
the Agent or such Bank under the Loan Documents and (B) all Taxes payable by the
Agent or such Bank as a result of payments made by the Borrower (whether made to
a taxing authority or to the Agent or such Bank) pursuant to this Section
1.13(b).

          (c)  Limitations.
               ----------- 

     Notwithstanding anything to the contrary contained herein, the Borrower
shall not be required to pay any additional amount in respect of withholding
taxes pursuant to this Section 1.13 to any Bank (A) in respect of any Bank Tax,
(B) except to the extent such Taxes are required to be withheld as a result of
(1) in the case of a Person that is a Bank on the Effective Date, a Regulatory
Change Enacted after the Effective Date and (2) in the case of a Person that
becomes a Bank after the Effective Date, a Regulatory Change Enacted after such
Person becomes a Bank, or (C) to the extent such withholding is required because
such Bank has failed to submit any form or certificate that it is entitled to so
submit under Applicable Law.

     Section 1.14  Pro Rata Treatment.
                   ------------------ 

     Except to the extent otherwise provided herein, (a) RC Loans of each Type
to be made on any day shall be made by the Banks pro rata in accordance with
their respective Commitments, (b) RC Loans of the Banks shall be converted and
continued pro rata in accordance with their respective amounts of RC Loans of
the Type and, in the case of Eurodollar Rate Loans, having the Interest Period
being so converted or continued, (c) each reduction in the Commitments shall be
made pro rata in accordance with the respective amounts thereof and  (d) each
payment of the principal of or interest on the Loans or of fees shall be made
for the account of the Banks pro rata in accordance with the respective amounts
thereof then due and payable.

respect to any such Benefit Plan, except that no event or condition referred to

Section 6.01(f)) and in every such event, the Agent, upon notice to the
Borrower, may do either or both of the following:  (a) declare, in whole or,
from time to time, in part, the principal of and interest on the Loans and the
Notes and all other amounts owing under the Borrower Loan Documents to be, and
the Loans and the Notes and all such other amounts shall thereupon and to that
extent become, due and payable and (b) terminate, in whole or, from time to
time, in part, the Commitments.  Upon the occurrence of an Event of Default

Borrower, (a) the principal of and interest on the Loans and the Notes and all
other amounts owing under the Borrower Loan Documents shall be due and payable

of any kind (other than the notice provided for in the first sentence of this

     Each Banks' obligations to make, continue or convert into Eurodollar Rate
Loans of any Type shall be suspended, all outstanding Loans of that Type shall
be converted on the last day of their applicable Interest Periods (or, if
earlier, in the case of clause (b) below, on the last day the Bank may lawfully
continue to maintain Loans of that Type or, in the case of clause (c) below, on
the day determined by such Bank to be the last Business Day before the effective
date of the applicable restriction) into, and all pending requests for the
making or continuation of or conversion into Loans of such Type shall be deemed
requests for, Base Rate Loans, if:

          

    (a)   on or prior to the determination of an interest rate for a Eurodollar
Rate Loan of that Type for any Interest Period, such Bank determines that for
any reason appropriate quotations are not available to it (including, in the
case of the Eurodollar Rate, quotations in the London interbank market for
deposits with it) for purposes of determining the Eurodollar Rate for such
Interest Period or that such rate would not accurately reflect the cost to such
Bank of making, continuing or converting into a Eurodollar Rate Loan of such
Type for such Interest Period;

          

    (b)   at any time such Bank determines that any Regulatory Change Enacted
after the Effective Date makes it unlawful or impracticable for the Bank or the
applicable Lending Office to make, continue or convert into any Eurodollar Rate
Loan of that Type, or to comply with its obligations hereunder in respect
thereof; or

          

    (c)   such Bank determines that, by reason of any Regulatory Change Enacted
after the Effective Date, the Bank or the applicable Lending Office is

     Such Bank shall promptly notify the Borrower of any circumstance that would
make the provisions of this Section 7.01 applicable, but the failure to give any
such notice shall not affect such Bank's rights hereunder.

     Section 7.02  Regulatory Changes.
                   ------------------ 

     If in the determination of any Bank (a) any Regulatory Change Enacted after
the Effective Date shall directly or indirectly (i) reduce the amount of any sum
received or receivable by such Bank with respect to any Loan or the return to be
earned by such Bank on such Loan, (ii) impose a cost on such Bank or any
Affiliate of such Bank that is attributable to the making, funding or
maintaining of, or such Bank's commitment to make, any Loan or to purchase a
participation in any Swing Loan, (iii) require such Bank or any Affiliate of
such Bank to make any payment on or calculated by reference to the gross amount
of any amount received by such Bank under any Loan Document or (iv) reduce, or
have the effect of reducing, the rate of return on any capital of such Bank or
any Affiliate of such Bank that such Bank or such Affiliate is required to
maintain on account of any Loan or such Bank's commitment to make any Loan or to
purchase a participation in any Swing Loan and (b) such reduction, increased
cost or payment shall not be fully compensated for by an adjustment in the
applicable rates of interest payable under the Loan Documents, then the Borrower
shall pay to such Bank such additional amounts as such Bank determines will,
together with any adjustment in the applicable rates of interest payable
hereunder, fully compensate for such reduction, increased cost or payment.  Such
additional amounts shall be payable, in the case of those applicable to prior
periods, within 15 days after request by such Bank for such payment and, in the
case of those applicable to future periods, on the dates specified, or
determined in accordance with a method specified, by such Bank.  Each Bank will
promptly notify the Borrower of any determination made by it referred to in
clauses (a) and (b) above, but the failure to give such notice shall not affect
such Bank's right to compensation.

     Section 7.03  Capital Requirements.
                   -------------------- 

     If, in the determination of any Bank, such Bank or any Affiliate of such
Bank is required, as a result of any Regulatory Change Enacted after the
Effective Date, to maintain capital on account of any Loan or such Bank's
commitment to make any Loan or to purchase a participation in any Swing Loan,
then, upon request by such Bank, the Borrower shall from time to time thereafter
pay to such Bank such additional amounts as such Bank determines will fully
compensate for any reduction in the rate of return on the capital that such Bank
or such Affiliate is so required to maintain on account of such Loan or
commitment suffered as a result of such capital requirement.  Such additional
amounts shall be payable, in the case of those applicable to prior periods,
within 15 days after request by such Bank for such payment and, in the case of
those relating to future periods, on the dates specified, or determined in
accordance with a method specified, by such Bank.

     Section 7.04  Funding Losses.
                   --------------

as such Bank determines are necessary to compensate it for any loss, cost or
expense incurred by it as a result of (a) in the case of Eurodollar Rate Loans,

other than the last day of an Interest Period for such Eurodollar Rate Loan or
(ii) a Eurodollar Rate Loan for any reason not being made or converted, or any
payment of principal thereof or interest thereon not being made, on the date
therefor determined in accordance with the applicable provisions of this
Agreement, and (b) in the case of Agreed Rate Loans, (i) any payment or
prepayment of an Agreed Rate Loan on a date other than the last day of an Agreed
Rate Interest Period or (ii) an Agreed Rate

interest thereon not being made, on the date required therefor determined in
accordance with the applicable provisions of this Agreement, including any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period after any such payment or conversion or
failure to borrow, convert, continue or prepay.

     Section 7.05  Certain Determinations.
                   ---------------------- 

     In making the determinations contemplated by Sections 7.01, 7.02, 7.03 and
7.04, each Bank may make such estimates, assumptions, allocations and the like
that such Bank in good faith determines to be appropriate, and each Bank's
selection thereof in accordance with this Section 7.05, and the determinations
made by such Bank on the basis thereof, shall be final, binding and conclusive
upon the Borrower, except, in the case of such determinations, for manifest
errors in computation or transmission.  Each Bank shall furnish to the Borrower
upon request a certificate outlining in reasonable detail the computation of any
amounts claimed by it under Sections 7.02, 7.03 and 7.04 and the assumptions
underlying such computations.

     Section 7.06  Change of Lending Office.
                   ------------------------ 

     If an event occurs with respect to a Lending Office that obligates the
Borrower to pay any amount under Section 1.13, makes operable the provisions of
clause (b) or (c) of Section 7.01 or entitles any Bank to make a claim under
Section 1.13(a), 7.02 or 7.03, such Bank shall, if requested by the Borrower,
use reasonable efforts to designate another Lending Office or Offices the
designation of which will reduce the amount the Borrower is so obligated to pay,
eliminate such operability or reduce the amount such Bank is so entitled to
claim, provided that such designation would not, in the sole and absolute
discretion of such Bank, be disadvantageous to such Bank in any manner or
contrary to Bank policy.  Each Bank may at any time and from time to time change
any Lending Office and shall give notice of any such change to the Borrower.
Except in the case of a change in Lending Offices made at the request of the
Borrower, the designation of a new Lending Office by any Bank shall not obligate
the Borrower to pay any amount to such Bank under Section 1.13, make operable
the provisions of clause (b) or (c) of Section 7.01 or entitle the Bank to make
a claim under Section 1.13(a), 7.02 or 7.03 if such obligation, the operability
of such clause or such claim results solely from such designation and not from a
Regulatory Change Enacted thereafter.

Agent hereby agrees, to act as the agent for such Bank under the Loan Documents
with such powers as are delegated to the Agent by the terms thereof, together
with such other powers as are reasonably incidental thereto.  The Agent's duties
shall be purely ministerial and it shall have no duties or responsibilities
except those expressly set forth in the Loan Documents.  The Agent shall not be
required under any circumstances to take any action that, in its judgment, (a)
is contrary to any provision of the Loan Documents or Applicable Law or (b)
would expose it to any Liability or expense against which it has not been
indemnified to its satisfaction.  The Agent shall not, by reason of its serving
as the Agent, be a trustee or other fiduciary for any Bank.

                   ------------------------------- 

     Neither the Agent nor any of its directors, officers, employees or agents
shall be liable or responsible for any action taken or omitted to be taken by it
or them under or in connection with the Loan Documents, except for its or their
own gross negligence, willful misconduct or knowing violations of law.  The
Agent shall not be responsible to any Bank for (a) any recitals, statements,
representations or warranties contained in the Loan Documents or in any
certificate or other document referred to or provided for in, or received by any
of the Banks under, the Loan Documents, (b) the validity, effectiveness or
enforceability of the Loan Documents or any such certificate or other document
or (c) any failure by the Loan Parties to perform any of their obligations under
the Loan Documents.  The Agent may employ agents and attorneys-in-fact and shall
not be responsible for the negligence or misconduct of any such agents or
attorneys-in-fact so long as the Agent was not grossly negligent in selecting or
directing such agents or attorneys-in-fact.  The Agent shall be entitled to rely
upon any certification, notice or other communication (including any thereof by
telephone, telex, telecopier, telegram or cable) believed by it to be genuine
and correct and to have been signed or given by or on behalf of the proper
Person or Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Agent.  As to any matters not
expressly provided for by the Loan Documents, the Agent shall in all cases be
fully protected in acting, or in refraining from acting, under the Loan
Documents in accordance with instructions signed by the Required Banks, and such
instructions of the Required Banks and any action taken or failure to act
pursuant thereto shall be binding on all of the Banks.

     Section 8.03  Defaults.
                   -------- 

     The Agent shall not be deemed to have knowledge of the occurrence of a
Default (other than the non-payment to it of principal of or interest on Loans
or fees) unless the Agent has received notice from a Bank or the Borrower
specifying such Default and stating that such notice is a "Notice of Default".
In the event that the Agent has knowledge of such a non-payment or receives such
a notice of the occurrence of a Default, the Agent shall give prompt notice
thereof to the Banks.  In the event of any Default, the Agent shall (a) in the
case of a Default that constitutes an Event of Default, take either or both of
the actions referred to in clauses (a) and (b) of the first sentence of Section
6.02 if so directed by the Required Banks and (b) in the case of any Default,
take such other action with respect to such Default as shall be reasonably
directed by the Required Banks.  Unless and until the Agent shall have received
such directions, in the event of any Default, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interests of the Banks.

     Section 8.04  Rights as a Bank.
                   ---------------- 

     Each Person acting as the Agent that is also a Bank shall, in its capacity
as a Bank, have the same rights and powers under the Loan Documents as any other
Bank and may exercise the same as though it were not acting as the Agent, and
the term "Bank" or "Banks" shall include such Person in its individual capacity.
Each Person acting as the Agent (whether or not such Person is a Bank) and its
Affiliates may (without having to account therefor to any Bank) accept deposits
from, lend money to and generally engage in any kind of banking, trust or other
business with the Loan Parties and their Affiliates as if it were not acting as
the Agent, and such Person and its Affiliates may accept fees and other
consideration from the Loan Parties and their Affiliates for services in
connection with the Loan Documents or otherwise without having to account for
the same to the Banks.

                   --------------- 

     The Banks agree to indemnify the Agent (to the extent not reimbursed by the
Loan Parties under the Loan Documents), ratably on the basis of the respective
aggregate principal amounts of the Exposures of the Banks (or, if no Exposures
are at the time outstanding, ratably on the basis of their respective
Commitments), for any and all Liabilities, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature
whatsoever that may be imposed on, incurred by or asserted against the Agent
(including the costs and expenses that the Loan Parties are obligated to pay
under the Loan Documents) in any way relating to or arising out of the Loan
Documents or any other documents contemplated thereby or referred to therein or
the transactions contemplated thereby or the enforcement of any of the terms
thereof or of any such other documents, provided that no Bank shall be liable
for any of the foregoing to the extent (a) they are subject to the indemnity
contemplated by the last sentence of Section 10.10(b) or (b) they arise from
gross negligence, willful misconduct or knowing violations of law by the Agent.

     Section 8.06  Non-Reliance on Agent and Other Banks.
                   ------------------------------------- 

     Each Bank agrees that it has made and will continue to make, independently
and without reliance on the Agent or any other Bank, and based on such documents
and information as it deems appropriate, its own credit analysis of the Loan
Parties and its own decision to enter into the Loan Documents and to take or
refrain from taking any action in connection therewith.  The Agent shall not be
required to keep itself informed as to the performance or observance by the Loan
Parties of the Loan Documents or any other document referred to or provided for
therein or to inspect the properties or books of any Loan Party or any
Subsidiary thereof.  Except for notices, reports and other documents and
information expressly required to be furnished to the Banks by the Agent under
the Loan Documents, the Agent shall have no obligation to provide any Bank with
any information concerning the business, status or condition of any Loan Party
or any Subsidiary thereof or the Loan Documents that may come into the
possession of the Agent or any of its Affiliates.

of and on behalf of such Bank, any Loan Document requiring execution by or on
behalf of such Bank.

                   ------------------------ 

     The Agent may at any time give notice of its resignation to the Banks and
the Borrower.  Upon receipt of any such notice of resignation, the Required
Banks may, after consultation with the Borrower, appoint a successor Agent.  If
no successor Agent shall have been so appointed by the Required Banks and shall
have accepted such appointment within 30 days after the retiring Agent's giving
of notice of resignation, then the retiring Agent may, on behalf of the Banks
and after consultation with the Borrower, appoint a successor Agent.  Upon the
acceptance by any Person of its appointment as a successor Agent, such Person
shall thereupon succeed to and become vested with all the rights, powers,
privileges, duties and obligations of the retiring Agent and the retiring Agent
shall be discharged from its duties and obligations as Agent under the Loan
Documents.  After any retiring Agent's resignation as Agent, the provisions of
this  Article 8 shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as the Agent.

     Section 9.01  Guaranty of Payment.
                   ------------------- 

     The Borrower and each of the Guarantors hereby (a) guarantees to each Bank
and each holder of a Note the due and punctual payment of all of the Guaranteed
Obligations (other than those that constitute Liabilities of such Guarantor) in
accordance with their respective terms and when and as due (whether at maturity,
by reason of acceleration or otherwise), or deemed to be due pursuant to Section
9.03, and (b) agrees so to pay the same when so due, or deemed to be due, upon
demand.

     Section 9.02  Limitation on Guaranty.
                   ---------------------- 

     It is the intention of the Borrower, each of the Guarantors and the Banks
that the obligations of the Borrower and each such Guarantor hereunder shall be
in, but not in excess of, the maximum amount permitted by Applicable Law.  To
that end, but only to the extent such obligations would otherwise be void,
voidable or otherwise unenforceable, the obligations of the Borrower and each
such Guarantor hereunder shall be limited to the maximum amount that would not
make such obligations void, voidable or otherwise unenforceable.  This Section
9.02 is intended solely to preserve the rights of each Bank and each holder of a
Note hereunder to the maximum extent permitted by Applicable Law, and neither
the Borrower, any Guarantor nor any other Person shall have any right under this
Section 9.02 that it would not otherwise have under Applicable Law.

automatic acceleration of any Guaranteed Obligations shall occur;

          

    (b)   any injunction, stay or the like that enjoins any acceleration, or
demand for the payment of any Guaranteed Obligations that would otherwise be
required or permitted hereunder shall become effective; or

          

    (c)   any Guaranteed Obligations shall be or be determined to be or become
discharged, disallowed, invalid, illegal, void or otherwise unenforceable
(whether by operation of any present or future law or by order of any court or
governmental agency) against the Borrower; then (i) such Guaranteed Obligations
shall, for all purposes hereof, be deemed (A) in the case of clause (c), to
continue to be outstanding and in full force and effect notwithstanding the
unenforceability thereof against the Borrower and (B) if such is not already the
case, to have thereupon become immediately due and payable and, if subject
thereto, to have commenced bearing interest at the Post-Default Rate and (ii)
such Bank or other holder of a Note to which such Guaranteed Obligations are
owing may, with respect to such Guaranteed Obligations, exercise all of the
rights and remedies under the Borrower Loan Documents that would be available to
them during an Event of Default.

     Section 9.04  Recovered Payments.
                   ------------------ 

     The Guaranteed Obligations shall be deemed not to have been paid, and the
Borrower's and each Guarantor's obligations hereunder in respect thereof shall
continue and not be discharged, to the extent that any payment thereof by the

Borrower or any other guarantor, or out of the proceeds of any collateral, is
recovered from or paid over by or for the account of any Bank or other holder of
a Note for any reason, including as a preference or fraudulent transfer or by
virtue of any subordination (whether present or future or contractual or
otherwise) of the Guaranteed Obligations, whether such recovery or payment over
is effected by any judgment, decree or order of any court or governmental
agency, by any plan of reorganization or by settlement or compromise by such
Bank or other holder of a Note (whether or not consented to by the Borrower, any
Guarantor or any other guarantor) of any claim for any such recovery or payment
over.  The Borrower and each Guarantor hereby expressly waives the benefit of
any applicable statute of limitations and agrees that it shall be liable
hereunder with respect to any Guaranteed Obligation whenever such a recovery or
payment over thereof occurs.

     Section 9.05  Evidence of Guaranteed Obligations.
                   ---------------------------------- 

     The records of the Agent and each Bank or other holder of a Note shall be
conclusive evidence of the Guaranteed Obligations owing to it and of all
payments in respect thereof.

     Section 9.06  Binding Nature of Certain Adjudications.
                   --------------------------------------- 

     The Borrower and each Guarantor shall be conclusively bound by the
adjudication in any action or proceeding, legal or otherwise, involving any
controversy arising under, in connection with, or in any way related to, any of
the Guaranteed Obligations, and by a judgment, award or decree entered therein.

     Section 9.07  Nature of Guarantor's Obligations.

     The Borrower's and each Guarantor's obligations hereunder (a) are absolute
and unconditional, (b) are unlimited in amount except as provided in Section
9.02, (c) constitute a guaranty of payment and not a guaranty of collection, (d)
are as primary obligor and not as a surety only, (e) shall be a continuing
guaranty of all present and future Guaranteed Obligations and all promissory
notes and other documentation given in extension or renewal or substitution for
any of the Guaranteed Obligations and (f) shall be irrevocable.

                    ----------------------- 

     The various rights and remedies of the Agent and each of the Banks under

Agent and each of the Banks shall be entitled to obtain a decree requiring
specific performance of each such right and remedy.

     Section 10.05  Rights Cumulative.
                    ----------------- 

     Each of the rights and remedies of the Agent and the Banks under the Loan
Documents shall be in addition to all of its other rights and remedies under the
Loan Documents and Applicable Law, and nothing in the Loan Documents shall be
construed as limiting any such rights or remedies.

     Section 10.06  Disclosures.
                    ----------- 

     The Agent and the Banks shall maintain the confidentiality of non-public

                                                                      --------

Agent or the Banks from disclosing such information (i) to its officers,

     Section 10.07  Amendments; Waivers.
                    ------------------- 

     Any term, covenant, agreement or condition of the Borrower Loan Documents
may be amended, and any right under the Borrower Loan Documents may be waived,
if, but only if, such amendment or waiver is in writing and is signed by the
Required Banks and, if the rights and duties of the Agent or the Swing Line Bank
are affected thereby, by the Agent or the Swing Line Bank, as the case may be,
and, in the case of an amendment, by the Borrower; provided, however, that no
amendment or waiver shall be effective, unless in writing and signed by each
Bank affected thereby, to the extent it (A) changes the amount of such Bank's
Commitment, (B) reduces the principal of or the rate of interest on such Bank's
Loans or Note or the fees payable to such Bank hereunder, (C) postpones any date
fixed for any payment of principal of or interest on such Bank's Loans or Note
or the fees payable to such Bank hereunder or (D) amends Section 1.14, this
Section 10.07 or any other provision of this Agreement requiring the consent or
other action of all of the Banks. Unless otherwise specified in such waiver, a
waiver of any right under the Borrower Loan Documents shall be effective only in
the specific instance and for the specific purpose for which given. No election
not to exercise, failure to exercise or delay in exercising any right, nor any
course of dealing or performance, shall operate as a waiver of any right of any
Bank under the Borrower Loan Documents or Applicable Law, nor shall any single
or partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right of the Agent or any Bank under the
Borrower Loan Documents or Applicable Law.

     Section 10.08  Set-Off; Suspension of Payment and Performance.
                    ---------------------------------------------- 

     The Agent and each Bank is hereby authorized by the Borrower and each
Guarantor, at any time and from time to time, without notice, during any Event
of Default, to set off against, and to appropriate and apply to the payment of,
the Liabilities of such Person under the Loan Documents (whether owing to the
Agent or such Bank or to any other Person that is the Agent or a Bank and
whether matured or unmatured, fixed or contingent or liquidated or unliquidated)
any and all Liabilities owing by the Agent or such Bank or any of its Affiliates
to such Person (whether payable in Dollars or any other currency, whether
matured or unmatured and, in the case of Liabilities that are deposits, whether
general or special, time or demand and however evidenced and whether maintained
at a branch or office located within or without the United States).

     Section 10.09  Sharing of Recoveries.
                    --------------------- 

          

    (a)   Each Bank agrees that, if, for any reason, including as a result of
(i)  the exercise of any right  of counterclaim, set-off, banker's lien or
similar right,  (ii)  its claim in any applicable bankruptcy, insolvency or
other similar law being deemed secured by a Debt owed by it to any Loan Party,
including a claim deemed secured under Section 506 of the Bankruptcy Code, or
(iii)  the allocation of payments by the Agent or any Loan Party in a manner
contrary to the provisions of Section 1.14, such Bank shall receive 

                                       38
<PAGE>
 
payment of a proportion of the aggregate amount due and payable to it hereunder
(A) as principal of or interest on the RC Loans or (B) fees that is greater than
the proportion received by any other Bank in respect of the respective
aggregates of such amounts due and payable to such other Bank hereunder, then
the Bank receiving such proportionately greater payment shall purchase
participations (which it shall be deemed to have done simultaneously upon the
receipt of such payment) in the rights of the other Banks hereunder in such RC
Loans or fees, as the case may be, so that all such recoveries with respect to
such respective amounts due and payable hereunder (net of costs of collection)
shall be pro rata; provided, that if all or part of such proportionately greater
payment received by the purchasing Bank is thereafter recovered by or on behalf
of any Loan Party from such Bank, such purchases shall be rescinded and the
purchase prices paid for such participations shall be returned to such Bank to
the extent of such recovery, but without interest (unless the purchasing Bank is
required to pay interest on the amount recovered to the Person recovering such
amount, in which case the selling Bank shall be required to pay interest at a
like rate). The Borrower expressly consents to the foregoing arrangements and
agrees that any holder of a participation in any rights hereunder so purchased
or acquired pursuant to this Section 10.09(a) shall, with respect to such
participation be entitled to all of the rights of a Bank under Sections 7.02,
10.02 and 10.08 (subject to any condition imposed on a Bank hereunder with
respect thereto) and may exercise any and all rights of set-off with respect to
such participation as fully as though the Borrower were directly indebted to the
holder of such participation for Loans in the amount of such participation.

          

    (b)   Each Bank agrees to exercise any right of counterclaim, set-off,
banker's lien or similar right that it may have in respect of any Loan Party in
a manner so as to apportion the amount subject to such exercise, on a pro rata
basis, first, between  (i)  obligations of such Loan Party for amounts subject
to the sharing provisions of Section 10.09(a) and (ii) other Liabilities of such
Loan Party and, second, with respect to amounts allocated to obligations of such
Loan Party referred to in clause (i), between, first, to RC Loans and second,
participations in Swing Loans.

     Section 10.10  Assignments and Participations.
                    ------------------------------ 

          (a)  Assignments.
               ----------- 

    (i)   Neither the Borrower nor any Guarantor may assign any of its rights or
obligations under the Borrower Loan Documents without the prior written consent
of each Bank, and no assignment of any such obligation shall release the
Borrower or such Guarantor therefrom unless each Bank, as applicable, shall have
consented to such release in a writing specifically referring to the obligation
from which the Borrower or such Guarantor is to be released.

               

    (ii)  Each Bank may from time to time assign any or all of its rights and
obligations under the Borrower Loan Documents to one or more Persons; provided
                                                                      --------
that, except in the case of the grant of a security interest to a Federal
Reserve Bank (which may be made without condition or restriction), no such
assignment shall be effective unless (A) the assignment is consented to by the
Agent and, unless a Bankruptcy Default with respect to the Borrower or a
Guarantor exists, the Borrower and the Guarantors, (B)  the assignment shall
involve the assignment of not less than $5,000,000 of the assignor Bank's
Commitment, (C) a Notice of Assignment with respect to the assignment, duly
executed by the assignor and the assignee, shall have been given to the Borrower
and the Agent and  (D)  except in the case of an assignment by the Bank that is
the Agent, the Agent shall have been paid an assignment fee of $3,500.  Upon any
effective assignment, the assignee shall have all of the rights and shall be
obligated to 

                                       39
<PAGE>
 
perform all of the obligations of a Bank; provided, however, that no assignee 
                                          --------  -------      
shall be entitled to any amounts that would otherwise be payable to it with
respect to its assignment under Section 7.02 unless (x) such amounts are payable
in respect of a Regulatory Change Enacted after the date the applicable
assignment agreement was executed or (y) such amounts would have been payable to
the Bank that made such assignment if such assignment had not been made. In the
event of any effective assignment by a Bank, the Borrower shall, against (except
in the case of a partial assignment) receipt of the existing Note of the
assignor Bank, issue a new Note to the assignee Bank.

          (b)  Participation.
               ------------- 

          Each Bank may from time to time sell or otherwise grant participations
in any or all of its rights and obligations under the Borrower Loan Documents
without the consent of the Borrower, any Guarantor, the Agent or any other Bank.
In the event of any such grant by a Bank of a participation, such Bank's
obligations under the Loan Documents to the other parties thereto shall remain
unchanged, such Bank shall remain solely responsible for the performance
thereof, and the Borrower, the Guarantors, the Agent and the other Banks may
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations thereunder.  A Bank may not grant to any holder of
a participation the right to require such Bank to take or omit to take any
action under the Loan Documents, except that a Bank may grant to any such holder
the right to require such holder's consent to  (i)  reduce the principal of or
the rate of interest on such Bank's Loans or the fees payable to such Bank
hereunder,  (ii)  postpone any date fixed for any payment of principal or of
interest on such Bank's Loans or the fees payable to such Bank hereunder,  (iii)
permit any Loan Party to assign any of its obligations under the Loan Documents
to any other Person or  (iv)  release any Guarantor from its obligations under
Article 9.  Each holder of a participation in any rights under the Borrower Loan
Documents, if and to the extent the applicable participation agreement so
provides, shall, with respect to such participation, be entitled to all of the
