Recent Developments

     On August 7, 1998, Pittway Corporation completed the tax-free spinoff of
Penton Media, Inc. (the "Company") in a one-for-one distribution of our common
stock for each share of Pittway Corporation stock outstanding, regardless of
class. Immediately following the distribution, we acquired Donohue Meehan
Publishing Company ("DM Publishing"). DM Publishing published three magazines
in the baking and convenience store markets: Modern Baking, Baking Management
and Convenience Store Decisions. It also produced a number of related special
editions and directory and show issues serving the baking and convenience store
markets.

     Prior to the spin-off and our acquisition of DM Publishing we acquired the
following three trade show companies in 1997 for a combined purchase price of
$48.1 million plus contingent payments of up to $13.5 million based on future
earnings:

       -      SYSTEM International ("A/E/C"), which produces conference and
              trade show events for computer and high-tech solutions in the
              architectural, engineering, and construction industries;

       -      Industrial Shows of America ("ISOA"), which produces 24 industrial
              trade shows in the United States and Latin America that focus on
              the machine tool, plant maintenance, supply chain and
              heating/ventilating/air conditioning markets; and

       -      Independent Exhibitions Limited, Equity Information Exchange
              Limited and Service Exhibitions Limited (collectively referred to
              herein as "INDEX"), which is an owner and producer of eight trade
              shows serving the computer, manufacturing and leisure markets in
              the United Kingdom.

       Our strategy to focus on core market segments led to three dispositions
in the 1990s. In 1995, we sold Progressive Architecture magazine, which was a
stand-alone title for our Company in the market it served. Also, in 1995, we
exchanged our Millimeter magazine, a market leader but a stand-alone in serving
the motion picture, television and video production industry, for EEPN magazine,
a property that strengthened our portfolio in the electronic engineering
market. In 1997, we sold Managing Office Technology magazine because the market
served did not fit our strategic plans.

       On October 7, 1998, along with our wholly owned subsidiary, Internet
World Media, Inc., we entered into a merger agreement with Mecklermedia
Corporation ("Mecklermedia") and Alan M. Meckler, its controlling stockholder,
pursuant to which Internet World Media, Inc. launched a tender offer for the
outstanding common stock of Mecklermedia for $29.00 per share. Following the
tender offer, Internet World Media, Inc. merged with and into Mecklermedia, with
Mecklermedia continuing as the surviving corporation.  The transaction value of
the tender offer and the merger was approximately $273.8 million. 


       Mecklermedia provides information through the Internet through its:

              -      Internet World trade shows and conferences;

              -      publication of Internet World, a weekly 
                     business-to-business controlled circulation newspaper;

              -      Boardwatch magazine;

              -      ISP Directory; and

              -      ISPCON Trade shows.

       In May 1998, Mecklermedia acquired all of the outstanding capital stock
of Boardwatch, Inc. and One, Inc. Boardwatch is the publisher of the monthly
trade magazine Boardwatch and One, Inc. is the producer of the ISPCON trade
shows. 

Domestic and Foreign Revenues and Assets

       Domestic sales of our products and services comprised 97.7%, 96.9% and
92.3% of total revenues for the fiscal years ended December 31, 1996, 1997 and
1998, respectively. Foreign sales totaled 2.9%, 3.1% and 7.7% of our revenues
for the fiscal years  ended December 31, 1996, 1997 and 1998, respectively. In
1998, 77% of these foreign sales were to customers in the United Kingdom.
Substantially all of the United Kingdom sales were made by INDEX, a subsidiary
of Penton located in the United Kingdom.

       We intend to further expand into international markets. We have limited
experience in developing localized versions of our publications and trade shows
and conferences and in marketing and distributing them internationally. In
addition, the following risks in international markets could have a material
adverse effect on our future international operations and, consequently, on our
business, results of operations and financial condition:

       -      the uncertainty of product acceptance by different cultures;

       -      the risks of divergent business expectations or cultural 
              incompatibility inherent in establishing joint ventures with 
              foreign partners;

       -      difficulties in staffing and managing multi-national operations;

       -      currency fluctuations;
   
       -      general economic and political uncertainties and potential for 
              social unrest;

       -      limitations on our ability to enforce legal rights and remedies;

       -      state-imposed restrictions on the repatriation of funds; and

       -      potentially adverse tax consequences.

       See Note 15 of the Notes to Consolidated Financial Statements included 
herein for a description of the Company's assets located in the United States 
and in the United Kingdom.

</TABLE>
 
 
PRODUCTS AND SERVICES
 
     We serve specific industry sectors with our business publications, our
trade shows and conferences and our electronic media products.
 
In Print: Publications
 
     Trade Magazines. We publish specialized trade magazines in the United
States. According to Advertising Age's annual ranking of magazines in the United
States, Penton publishes two of the ten largest business-to-business magazines,
based on advertising revenues. Our publications are widely recognized for the
quality of our editorial content. Since 1990, our magazines have won nearly 600
editorial awards.
 
     We publish 50 trade magazines with a combined circulation of over 3.2
million subscribers worldwide. Our magazines are primarily
controlled-circulation. They are distributed free-of-charge to qualified
subscribers in our targeted industries.
 
     Our publications generate revenues primarily from the sale of advertising
space. Subscribers to controlled-circulation publications qualify to receive our
magazines by verifying their responsibility for specific job functions,
including purchasing authority. We survey subscribers to our
controlled-circulation magazines annually to verify their continued
qualification.
 
     Circulation information for the majority of our publications is audited
each year by BPA International, an independent auditor of magazine circulation.
These audits verify that we have accurately identified the number and job
responsibilities of qualified subscribers and that those subscribers are,
eligible to receive the relevant publication according to our established
criteria.
 
     Each of our publications has its own advertising sales team and rate
structure. Some advertisers may qualify for discounts based on advertising in
multiple publications. We enable marketers to be more cost efficient in their
advertising purchases by providing a single source for integrated products.
 
     In addition, each of our publications has its own editorial staff,
including writers, designers and production personnel. To preserve the editorial
integrity of each publication's news reporting and analysis, we seek to maintain
separation between the editorial and sales staffs of each publication. We
believe that our reputation for objective, fair and credible editorial content
contributes significantly to our success. Fifteen of our publications have
served their industries for over 50 years.
 
     Our editorial staffs meet frequently with readers of their publications to
maintain a current understanding of the information needs and interests of those
readers in an effort to serve them more effectively. We devote considerable
resources to the study of trends in our industries and strive to make our
publications the most widely used among our targeted audiences. Many of our
editors and contributors are recognized as experts in their fields and are
regularly contacted by the general press to comment on developments and trends
in their respective markets.
 
     Directories and Buyer's Guides. We also publish 32 directories and buyer's
guides, which are respected sources of buying information for industry decision
makers. Most of the business directories we publish have limited competition.
 
IN PERSON: TRADE SHOWS AND CONFERENCES
 
     We produce 118 trade shows and conferences in our ten industry sectors. In
addition to these events, we maintain licensing agreements for 3 trade shows and
we produce 4 trade shows under management contracts.
 
     In the early 1990s, we entered the trade show and conference business and
have more recently expanded our presence through acquisitions. For example, the
acquisition of Mecklermedia in 1998 added the ISPCON and Internet World trade
shows to our portfolio. In addition, we recently expanded our global presence.
In 1997, we acquired INDEX, a United Kingdom-based producer of trade shows, and
ISOA, which is experienced in producing trade shows in Latin America.
 
     Attendees at our trade shows and conferences are professionals and managers
in the industries we serve. Most trade shows include an extensive conference
program, which provides a forum for the exchange and dissemination of
information relevant to the particular event's focus. In addition, most trade
shows have one or more "keynote" sessions with speakers who are known for their
industry knowledge and expertise.
 
     Trade show exhibitors pay a set price per square foot of booth space.
Typically, a majority of each trade show's exhibitors commit to booth space
during that year's show for the following year. In addition, Penton receives
revenues from attendee fees at trade shows and conferences
 
ONLINE: ELECTRONIC MEDIA
 
     Our presence in print and trade show media enables us to market our Web
sites in the industries that we serve. We believe the growth of
electronic publishing will provide opportunities to market existing and develop
new editorial content from our publications in different formats. We currently
maintain 42 Web sites.
 
OTHER
 
     We also provide ancillary information services that complement our
principal business media platforms. These services include:
 
          - Market Access & Business Development Services. We provide a variety
            of marketing services, including database rentals and research
            services. We use information from our subscription lists and other
            available databases to compile detailed mailing lists for rental by
            marketers who want to promote their products and services through
            direct mail programs. We offer these services to our customers to
            help them reach their targeted audience.
 
          - Specialized Advertising Services. We collect and forward reader
            inquiries to our advertisers. In addition, classified and
            recruitment advertising sections in our publications provide a
            cost-efficient medium for reaching prospects who are ready to buy
            specialized products and services. Also recruitment advertising
            provides an effective way to reach qualified professionals seeking
            career opportunities.
 
          - Custom Communications/Promotion. Penton Custom Publishing produces a
            full range of client-specific communications services for print,
            electronic media and the Internet, including newsletters, magazines,
            catalogs, directories, education and training materials, and other
            support materials.
 
          - Research. Penton Research Services offers a full range of primary
            and secondary research services for advertisers and industry
            associates. Primary research is used to develop original statistics
            and analysis based on a variety of research methodologies that may
            include interviews, surveys and focus groups. Secondary research
            makes use of existing research developed by other organizations,
            collating it to answer a specific research need.
 
 
CUSTOMERS
 
     We have more than 5,000 customers and our top ten customers in 1998
accounted for only 5.3% of our total revenue.
 
COMPETITION
 
     We experience intense competition for our products and services. We compete
with several much larger international firms that operate in many markets and
have broad product offerings in publishing, trade shows and conferences. We
compete for readers and advertisers in the publishing marketplace. We also
compete for trade show and exhibition expenditures, sponsorships and show
attendees in the trade show and conference marketplace. Because our industry is
relatively easy to enter, we anticipate that additional competitors may enter
these markets and intensify competition.
 
     Our publications compete on the basis of:
 
     - advertisers' perception of the target audience served by the magazine;
 
     - readers' preference for the publication's content;
 
     - reader's acceptance of the publication's authoritative position in its
       markets;
 
     - editorial quality;
 
     - quantity and quality of circulation;
 
     - readers' response to advertisers' products and services;
 
     - the strength of complementary products serving the same niche; and
 
     - the effectiveness of sales and customer service and advertising rates.
 
     Our trade shows and conferences compete on the basis of:
 
     - the availability of alternative venues,
 
     - the ability to define events for particular market segments and/or with
different strategic positioning,
 
     - the range of competition for exposition dollars, sponsorships and show
and conference attendees.
 
     In addition, in our trade show and conference business, we compete with
many industry associations and, in several countries, the trade show and
conference hall owner and operator may also be a competitor.
 
PRODUCTION AND DISTRIBUTION
 
     We print nearly all of our own magazines and about 50 outside titles at our
printing facility in Berea, Ohio. If additional printing capacity is needed, we
believe that outside printing services are readily available at competitive
prices.
 
     The principal raw material used in our print publications is paper. We
believe that the existing arrangements providing for the supply of paper are
adequate and that, in any event, alternative sources are available. Paper costs
accounted for about 8.1% of our total operating costs for the year ended
December 31, 1998. Paper prices are affected by a variety of factors, including
demand, capacity, pulp supply and general economic conditions.
 
     Substantially all of our publications and direct mail promotions are
delivered by the United States Postal Service within the continental United
States. Postage costs also represent a significant expense, accounting for about
6.8% of our total operating costs and expenses for the year ended December 31,
1998.
 
     We recently announced that we were seeking to explore strategic
alternatives for our printing facility.
 
TRADEMARKS AND INTELLECTUAL PROPERTY RIGHTS
 
     We regard our copyrights, trademarks, service marks and similar
intellectual property as critical to our success and rely upon copyright and
trademark laws, as well as confidentiality agreements with our employees and
others, to protect our rights. We pursue the registration of our material
trademarks in the United States and, depending upon use, in other countries.
Effective trademark and copyright protection may not be available in every
country in which our publications and services are available.
 
     We may be subject to claims of alleged infringement of our trademarks or
our licensees of trademarks and other intellectual property rights of third
parties from time to time in the ordinary course of business. We do not believe
that these legal proceedings or claims are likely to have, individually or in
the aggregate, a material adverse effect on our business, financial condition or
results of operations.

SEASONALITY

     For a discussion of seasonality, see Item 7 of this Annual Report on Form
10-K "Management's Discussion and Analysis of Financial Condition and Results
of Operations--Seasonality." 

ENVIRONMENTAL MATTERS
 
     We anticipate that compliance with various laws and regulations relating to
protection of the environment will not have a material effect on our capital
expenditures, earnings or competitive position.
 
LEGAL PROCEEDINGS
 
     A former shareholder of Mecklermedia, Ariff Alidina, filed suit against us
in the Federal District Court in the Southern District of New York for an
unspecified amount, as well as other relief. The plaintiff claims that we
violated the federal securities laws by selling Mr. Meckler an 80.1% interest in
internet.com for what the plaintiff alleges was a below-market price, thereby
giving to Mr. Meckler more consideration for his common stock in Mecklermedia
than was paid to other stockholders of Mecklermedia. We intend to vigorously
defend this suit and we have filed a motion to dismiss the lawsuit, which is
pending.
 
EMPLOYEES
 
     On December 31, 1998, we employed about 1,455 persons, primarily located in
the United States. None of our employees is represented by a labor union, and we
consider our relations with our employees to be good.

present needs.

Item 3.  LEGAL PROCEEDINGS.

     In connection with the acquisition of Mecklermedia Corporation, on December
1, 1998, a lawsuit was brought against the Company by Ariff Alidina (the
"Plaintiff") a former shareholder of Mecklermedia, in Federal District Court in
the Southern District of New York for an unspecified amount, as well as other
relief. The Plaintiff has claimed that the Company violated the federal
securities laws by selling Mr. Meckler, a beneficial owner of approximately 26%
of the shares of Mecklermedia, an 80.1% interest in internet.com for what the
Plaintiff alleges was a below-market price, thereby giving to Mr. Meckler more
consideration for his common stock in Mecklermedia than was paid to other
stockholders of Mecklermedia. The Company intends to vigorously defend this suit
and has filed a motion to dismiss the lawsuit, which is pending.

Item 6.  SELECTED FINANCIAL DATA.

     The following table summarizes limited financial data with respect to the
Company. The historical income statement data for each of the three years in the
period ended December 31, 1998 and balance sheet data as of December 31, 1997
and 1998 have been derived from the Company's audited annual financial
statements and related notes. The information set forth below should be read in
conjunction with our consolidated financial statements and related notes and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" appearing elsewhere herein. As you read the following, you should
consider that:
 
     - The Company defines EBITDA as operating income before depreciation and
       amortization. EBITDA is often used to analyze and compare companies on
       the basis of operating performance and cash flow. However, EBITDA is not
       adjusted for all non-cash expenses or for working capital, capital
       expenditures and other investment requirements. EBITDA should not be
       considered in isolation or as a substitute for measures of performance
       prepared in accordance with generally accepted accounting principles. Not
       all companies calculate EBITDA in the same manner, and EBITDA as
       presented may not be comparable to similarly titled measures presented by
       other companies.

Item 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.

                  
 
     Set forth below is a discussion and analysis of the Company's financial
condition and results of operations. Such discussion and analysis should be read
in conjunction with the financial statements and the related notes appearing
elsewhere herein.
 
OVERVIEW
 
     We are a leading business media company operating in three business
segments: media services, printing and direct mail marketing. Our media services
segment serves specific targeted industries with integrated product
offerings, including, trade magazines, trade shows and conferences, directories,
electronic media products (including Web sites), custom publishing, research,
databases and information products.

     Trade magazine revenues are generated primarily from advertising, which
accounted for 70.0% of total revenue in 1998, 76.0% in 1997 and 78.0% in 1996.
No single advertiser comprised more than 1.2% of our advertising revenue during
1998. The Company's top 10 advertisers accounted for 5.3% of total revenue and
its top 25 customers accounted for less than 8.7% of total revenues in 1998.

Trade show and conference revenues represented 12% of total revenues in 1998,
5.0% in 1997 and 3.0% in 1996. Trade show and conference revenues are derived
from exhibition and meeting space sales, registration fees, and ancillary
services which are recognized at the time of the show. Trade show exhibition
space sales are contracted and partial payment is received as far as one year in
advance of the show, although some refunds may occur prior to the show due to
cancellations. For example, 66% of budgeted exhibit space at our 1999 Internet
World Fall Show was reserved prior to the end of last year's show. Companies
that exhibit at trade shows pay on the basis of the space that their exhibit
occupies. Revenue and related direct event expenses are recognized in the month
in which the event is held. Cash is collected in advance of a trade show or
conference and is recorded on our balance sheet as deferred revenue. We expect
the percentage of total revenues from trade shows and conferences to increase as
a result of the acquisition of Mecklermedia. 

The printing segment prints magazines, catalogs, brochures and direct mail
pieces for the media services segment and outside commercial customers. The
direct mail segment serves primarily the pharmaceutical and business services
markets with the ability to design, produce, print and mail direct mail
campaigns. The Company has announced it is exploring strategic alternatives for
both its printing segment and direct mail segment.
 
The Company was spun off from Pittway Corporation in August 1998. On November
24, 1998, the Company acquired Mecklermedia, a provider of information about the
Internet through various business media products, for $273.8 million. On August
7, 1998, the Company acquired Donohue Meehan Publishing for $7.0 million in
cash, 1,541,638 shares of the Company's common stock and a contingent payment of
up to $4.0 million based on future earnings of Donohue Meehan Publishing.
Donohue Meehan Publishing publishes three magazines in the baking and
convenience store markets: Modern Baking, Baking Management and Convenience
Store Decisions. It also produces a number of related special editions and
directory and show issues serving the baking and convenience store markets. In
1997, Penton acquired three trade show companies -- Independent Exhibitions,
Ltd., Industrial Shows of America and A/E/C SYSTEMS International -- for a
combined purchase price of $48.1 million, plus contingent payments of up to
$13.5 million based on future earnings. All of these acquisitions were accounted
for using the purchase method of accounting and, accordingly, the results of the
acquired companies are included in the Company's consolidated statement of
income since their respective dates of acquisition.

million, or 13.8%, from $204.9 million to $233.1 million.
 
Media services revenues increased $26.5 million, or 14.6%, to $207.7 million.
Advertising revenues from the Company's publishing operations accounted for $7.1
million of the increase, due primarily to the following: (1) the Donohue Meehan
Publishing Company acquisition in August 1998; (2) two new publications launched
in the first quarter, IW Growing Companies and Embedded Systems Development; (3)
the publication of Hydraulics and Pneumatics' Fluid Power Handbook and
Directory, which is published every other year; and (4) higher pricing on other
advertising business. Trade show and conference revenues increased $17.2 million
to $28.0 million in 1998. About $12.0 million of the increase in 1998 was due to
the first-time inclusion of the operations of Independent Exhibitions, Ltd. and
about $5.0 million of this increase was due to Industrial Shows of America. Both
Independent Exhibitions and Industrial Shows of America were acquired in
December 1997. In addition, 1998 includes an increase in the Wireless
Symposium/Portable by Design Conference and Exhibition and approximately $0.8
million related to the addition of Mecklermedia in November 1998. The remaining
increase in media services revenues of $2.1 million relates to other
initiatives.

from 87.6% in 1997 to 88.5% in 1998. The increase in percentage was due
primarily to the increase in depreciation and amortization related to
acquisitions, period costs related to Mecklermedia Corporation and one-time
spin-off and start-up costs. These increases were offset partially by the first
full year of operations of Independent Exhibitions, Ltd. and Industrial Shows of
America.
 
     Editorial, Production and Circulation. Total editorial, production and
circulation expenses, after elimination of intersegment charges, grew to $101.8
million in 1998 compared with $94.6 million in 1997, representing an increase of
$7.2 million, or 7.6%. As a percentage of revenues, editorial, production and
circulation expenses decreased from 46.1% in 1997 to 43.7% in 1998. The decrease
is due largely to the acquisition of Donohue Meehan Publishing in 1998 and to
production improvements.
 
     Media services editorial, production and circulation expenses grew $5.7
million, or 6.9%, due to the inclusion of the Independent Exhibitions and
Industrial Shows of America trade shows acquired in late 1997, which accounted
for $4.7 million of the total production expenses increase. Other expense
increases relate to the acquisition of Donohue Meehan Publishing Company in
August 1998, the acquisition of Mecklermedia Corporation in November 1998 and
the publication of the biennial Fluid Power Handbook and Directory, which was
not published in 1997.
 
     Editorial, production and circulation expense for the printing segment
increased $1.8 million due to volume-related growth of the total business.
 
     Editorial, production and circulation expenses for the direct mail segment
decreased $0.3 million or 3.1% compared with a 3.6% increase in revenue. The
decrease is due largely to productivity improvements.
 
     Selling, General and Administrative. Total selling, general and
administrative expenses grew $15.4 million, or 19.5%, to $93.9 million. As a
percentage of revenues, selling, general and administrative expenses increased
from 38.3% in 1997 to 40.3% in 1998. The increase is due primarily to period
costs related to the acquisition of Mecklermedia Corporation  and one-time
spin-off costs.
 
     Media services selling, general and administrative expenses increased $15.5
million, or 21.6%. The increase was due to: (1) expenses of the Independent
Exhibitions, Ltd. and Industrial Shows of America trade shows held in 1998,
which amounted to $4.9 million and $3.7 million; (2) period costs of the newly
acquired Mecklermedia Corporation trade shows (for which revenues will not be
recognized until those trade shows are held in future periods) in the amount of
$1.7 million; (3) costs related to launching two new publications in the first
quarter, IW Growing Companies and Embedded Systems Development; (4) the Donohue
Meehan Publishing Company acquisition in August 1998; (5) one-time spin-off
costs of about $0.4 million; (6) costs related to the biennial Fluid Power
Handbook and Directory; (7) sales volume growth; and (8) higher charges related
to Pittway stock appreciation rights held by the Company's employees, which will
not recur. Total costs charged to the Company by Pittway for both 1998 and 1997
were $1.4 million.
 
     Selling, general and administrative expenses of the printing segment were
level with the prior year.
 
     Direct mail selling, general and administrative expenses decreased $0.2
million, or 4%, due primarily to cost-cutting measures implemented in 1998.
 
     Depreciation and Amortization. Depreciation and amortization increased
$4.2 million to $10.7 million. The higher expense was the result primarily of
the amortization of intangible assets associated with the trade shows acquired
in December 1997, the Donohue Meehan Publishing Company acquisition in August
1998, the Mecklermedia Corporation acquisition in November 1998 and, beginning
with the fourth quarter of 1998, the change in Penton's goodwill amortization
policy for acquired trade shows from 40 years to 20 years, which accounted for
$0.3 million of additional amortization in 1998. While this change will
negatively impact the reported earnings per share, it will have no impact on
either EBITDA or after-tax cash flow. The anticipated annual charges for
intangibles related to the Mecklermedia Corporation acquisition in 1999 and
future years is $14.5 million.
 
     Operating Income. Overall, the Company's operating income increased $1.4
million, or 5.6%, to $26.7 million from $25.3 million in the prior year.
Operating income as a percentage of revenue decreased from 12.3% to 11.5%, due
primarily to the increase in depreciation and amortization associated with
Penton's acquisitions.
 
     Media services operating income increased $1.5 million, or 5.5%. This
comprised an increase in publishing of 10.6% to $24.9 million, and a decrease in
trade shows and conferences from $2.5 million to $1.3 million. The increase in
publishing was the result primarily of the acquisition of Donohue Meehan
Publishing Company in 1998. The increase was offset by start-up costs associated
with two magazine launches in 1998, and one-time costs incurred from the
spinoff from Pittway. The decrease in trade shows and conferences was primarily
the result of period costs of the Mecklermedia Corporation acquisition (since
all of 1998's shows occurred prior to the acquisition), higher amortization
expense resulting from acquisitions and the change in Penton's amortization
policy noted above.
 
     Operating income of the printing segment decreased $0.7 million, to $0.8
million.
 
     The direct mail segment recorded an operating loss of $0.3 million compared
with the prior year's operating loss of $1.1 million. The improvement was due
largely to the increase in revenue of this segment's printing operations and
lower production costs.
 
     Interest Expense. Interest expense increased $4.7 million to $5.6 million
due to additional borrowings used to finance the two trade show company
acquisitions in December 1997, the Donohue Meehan Publishing Company acquisition
in August 1998 and the Mecklermedia Corporation acquisition in November 1998.
 
     Other. In 1998, the Company wrote down the carrying value of various
intangible assets by $1.0 million. In 1997, Penton recognized a $1.0 million
gain on the sale of Managing Office Technology magazine.
 
     Effective Tax Rates. The effective tax rates were 45.9% in 1998 and 41.7%
in 1997. The Company's acquisition of Donohue Meehan Publishing Company in
August 1998 and Mecklermedia Corporation in November 1998 resulted in the
recording of goodwill. The amortization of such goodwill is recognized for
financial statement purposes, but is not deductible for tax purposes due to the
structure of the purchase transactions. Accordingly, the company's effective tax
rate has increased in 1998 and is expected to increase in 1999 as well, due to
the full year effect of the acquisitions.
 
1997 COMPARED TO 1996
 
  Revenues
 
     Total revenues, after elimination of intersegment sales, increased $16.3
million, or 8.7%, from $188.6 million to $204.9 million.
 
     Media services revenues increased $14.5 million, or 8.7%, to $181.1
million. Revenues from publishing operations accounted for $9.1 million of the
improvement, due primarily to increased advertising revenues. Advertising
revenues grew 7.1%, resulting from a 1.9% growth in page volume and an overall
improvement of 4% in yield per advertising  page. In addition, the Company
benefitted from the introduction of four publications launched during 1997.
Trade show and conference revenues increased $5.4 million or 100% to $10.8
million due to the inclusion of a full year of operations of the A/E/C SYSTEMS
International trade shows, acquired in January 1997.
<PAGE>   7

     Revenues from the printing segment increased $1.2 million, or 3.1%, to
$39.0 million. The increase in this segment was due principally to the addition
of several new third-party customers, which accounted for a 19% increase in
outside revenue. The media services segment continued to be the printing
segment's principal customer, accounting for $28.6 million of its revenue in
1997 compared to $29.0 million in 1996.
 
     Direct mail revenues increased $0.2 million, or 1.5%, due to strong
performance from the related printing operation, which experienced a 25%, or
$1.8 million, increase in revenue from outside customers, and growth in its
advertising agency business. However, the increases were offset by a decline in
revenues of the direct marketing medical group. This group's revenues declined
for the second consecutive year as pharmaceutical company customers continued to
shift their focus from direct marketing of pharmaceuticals to consumer oriented
mass media advertising.
 
     Operating Expenses. Operating expenses, after elimination of intersegment
charges, increased $9.5 million, or 5.6%, from $170.1 million to $179.6 million.
As a percentage of revenues, operation costs decreased from 90.2% in 1996 to
87.7% in 1997. The improvement was due primarily to productivity improvements,
cost cutting measures and the acquisition of A/E/C SYSTEMS International in
January 1997.
 
     Editorial, Production and Circulation. Total editorial, production and
circulation expense, after elimination of intersegment charges, grew to $94.6
million in 1997 compared with $91.6 million in 1996, representing an increase of
$3.0 million, or 3.2%. As a percent of revenues, editorial, production and
circulation expenses decreased from 48.5% in 1996 to 46.1% in 1997. The decrease
was due primarily to the higher margins of the A/E/C SYSTEMS International trade
shows and lower paper expenses.
 
     Media services editorial, production and circulation expense increased $1.5
million, or 1.8%, to $80.4 million, due primarily to additional expenses related
to the inclusion of a full year's operations of A/E/C SYSTEMS International, new
product launches during the year and volume-related growth. These increases were
offset partially by savings resulting from productivity improvements and lower
paper expenses.
 
     Editorial, production and circulation expense for the printing segment
increased $0.6 million, or 2%, to $3.5 million, which was attributable primarily
to the increase in volume of outside sales.
 
     Editorial, production and circulation expense for the direct mail segment
increased $0.4 million, or 4.5%, to $9.3 million. The increase was attributable
primarily to the growth of printing and advertising agency group sales volume,
offset by a reduction in expenses attributable to lower sales volume of the
direct marketing medical group.
 
     Selling, General and Administrative Expense. Selling, general and
administrative costs of media services increased $5.3 million, or 8%. The
increase was due principally to an increase in selling expenses resulting from
the growth in revenue, inclusion of a full year's operations of the A/E/C
SYSTEMS International trade shows, and the addition of staff to support new
product launches.
 
     Selling, general and administrative expenses of the printing segment
increased $0.2 million, or 11%, primarily from selling expenses associated with
the increase in sales volume.
 
     Direct mail selling, general and administrative expenses increased $0.4
million as a result of increased selling costs associated with higher sales
volume and an expanded number of customer presentations and related promotion
costs.
 
     Depreciation and Amortization.  Depreciation and amortization increased
$0.6 million to $6.5 million. The higher expense was the result primarily of
capital equipment additions and increased amortization of intangible assets
associated with the A/E/C SYSTEMS International trade shows acquired in January
1997.
 
  Operating Income.  

     Overall, the Company's operating income increased $6.8 million, or 36.7%,
to $25.3 million compared with $18.5 million. Operating income as a percentage
of revenue increased to 12.3% from 9.8%, reflecting the benefits achieved from
increased revenue; favorable shifts in product mix, including the addition of
the A/E/C SYSTEMS International trade shows; and improved productivity.
 
     Media services operating income increased $7.2 million, or 40.6%, to $24.9
million. In 1995, Penton implemented a number of programs to improve
productivity, reduce costs and streamline operations. These efforts continued in
1997, resulting in operating savings. Combined with the favorable impact of
revenue growth, productivity improvement and reduced paper costs, operating
income improved from 10.6% of total media services revenue to 13.7%.
 
     Operating income from the printing segment improved 20.3% to $1.5 million.
The increase was due primarily to higher sales volume coupled with the benefits
of reduced paper costs.
 
     Direct mail operating losses increased $0.6 million to $1.1 million from
$0.5 million, due principally to the decrease in revenue of the direct marketing
medical group and development costs associated with a physicians retraining
program.
 
  Other Income (Expense)
 
     In 1997, other income (expense) included a $1.0 million gain on the sale of
Managing Office Technology magazine, offset by $0.8 million of interest expense
incurred as a result of borrowings used to finance acquisitions.
 
  Effective Tax Rates
 
     The effective tax rates were 41.7% and 40.7% in 1997 and 1996,
respectively. An analysis of Penton's effective tax rate appears in the
Company's consolidated financial statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Historically, cash flow generated by the Company's operations has been used
to invest in capital assets, finance acquisitions and reduce debt. Prior to the
spinoff's excess cash was used to pay dividends to Pittway Corporation, its
former parent company.
 
     Cash flow provided by operations in 1998 was $25.7 million, up $2.5 million
from $23.2 million in 1997. The increase in 1998 was due primarily to an
increase in unearned income (primarily advance deposits related to
fourth-quarter trade shows), accounts payable and accrued expenses. Partially
offsetting this increase were lower net income, increases in accounts
receivable, prepayments and deposits.
 
     Cash from operating activities was used for capital expenditures; to make
cash distributions to Pittway, including final settlement of intercompany
balances existing at the spin-off date; and to pay dividends to the Company's
stockholders. Capital expenditures for 1996 were $4.8 million, 1997 were $5.5
million and 1998 were $5.8 million. We anticipate that our total capital
expenditures for 1999 will be about $6.5 million, which will be used primarily
to upgrade Penton's information technology systems. We plan to fund these
expenditures from cash flow from operations, and, if necessary, borrowings under
our credit facilities.
 
     On August 7, 1998, the Company entered into a five-year, $75.0 million
unsecured revolving credit agreement. The Company's short-term notes payable
were refinanced with this facility, which was also utilized to finance the cash
portion of the acquisition price of Donohue Meehan Publishing Company. On
November 24, 1998, the Company entered into a credit agreement with several
banks under which it may borrow up to $325.0 million.
 
<PAGE>   8
     The agreement provides for a revolving loan facility of up to $25.0
million, a long-term loan of $175.0 million (Term Loan A) and a long-term loan
of $125.0 million (Term Loan B). The proceeds of this credit agreement were used
to repay Penton's debt outstanding under the $75.0 million revolving credit
facility obtained at the spin-off date and to purchase Mecklermedia Corporation.
At December 31, 1998, $306.0 million was outstanding under the credit agreement.
The Company and the banks intend to amend this agreement to enable the Company
to borrow an additional $15.0 million as part of the Term Loan B facility to be
effective in April 1999. 
 
     The Term Loans under this credit facility amortize quarterly. The Company
must repay Term Loan A in aggregate annual amounts of $10 million in each of
1999 and 2000, $20 million 2001, $25 million in 2002, $30 million in 2003, and
$40 million in 2004, with the balance payable in 2005. The Company must repay
Term Loan B in aggregate annual amounts of $1.25 million in each of 1999 through
2005, with the balance payable in 2006.

     The interest rate for borrowings under the Revolving Credit Facility and
Term Loan A is, at the option of the Company, LIBOR plus 2.75% or the Base Rate
plus 1.75%. After late May 1999, the interest rate for borrowings under the
Revolving Credit Facility and Term Loan A will become variable, ranging from
LIBOR plus 2.25% to 3.00% or the Base Rate plus 1.25% to 2.00%, depending on the
Company's debt to EBITDA ratio. The interest rate for Term Loan B is, at the
option of the Company, LIBOR plus 3.50% or the Base Rate plus 2.50%.

     The Company must pay quarterly fees for letters of credit issued under the
Credit Agreement. Currently, the Company must pay (i) a 0.25% per annum fee to
the issuing bank and (ii) a 2.75% per annum fee shared by all lenders, both of
which are based on the amount available for drawing under outstanding letters of
credit. After late May 1999, the latter fee will become variable, and will range
from 2.25% to 3.00% depending on the Company's debt to EBITDA ratio. 

     All existing (and future) domestic subsidiaries of the Company (the
"Guarantors") have guaranteed (or will guaranty) indebtedness incurred under the
Credit Agreement.

     The credit facility contains customary and appropriate representations and
warranties, including those relating to due organization and authorization,
enforceability, financial condition, no material adverse changes, title to
properties, liens, litigation, payment of taxes, no material adverse agreements,
employee benefit liabilities, environmental liabilities, perfection and priority
of liens securing debt incurred under the Credit Agreement, and full disclosure.

     The credit facility also contains customary affirmative and negative
covenants, including but not limited to furnishing information and limitations
on other indebtedness, liens, investments, guarantees, restricted payments,
mergers and acquisitions, sales of assets, capital expenditures, leases,
affiliate transactions, and conduct of business. The facility also contains
customary financial covenants, including those relating to: minimum interest
coverage, minimum fixed charge coverage, minimum EBITDA and maximum leverage.

     Events of default under the credit facility include events of default
relating to: (a) nonpayment of interest, principal or fees payable under the
credit facility; (b) nonperformance of covenants; (c) cross-default to other
material agreements and debt of the company and its subsidiaries; (d) bankruptcy
or insolvency; (e) judgments in excess of specified amounts; (f) impairment of
security interests in collateral; (g) invalidity of guarantees; (h) materially
inaccurate or false representations or warranties and (i) change of control.
 
     Based upon current and anticipated levels of operations, we believe that
our cash on hand and cash flow from operations, combined with borrowings
available under our credit facilities, will be sufficient to enable us to meet
our current and anticipated cash operating requirements, including scheduled
interest and principal payments, capital expenditures and working capital needs.
However, actual capital requirements may change, particularly as a result of any
acquisitions which we may make. Our ability to meet current and anticipated
operating requirements will be dependent upon our future performance which, in
turn, will be subject to general economic conditions and to financial, business
and other factors, including factors beyond our control. Depending on the
nature, size and timing of future acquisitions, we may be required to raise
additional capital through additional financing arrangements or the issuance of
private or public debt or equity securities of the Company. We cannot assure you
that such additional financing will be available on acceptable terms.
Substantially all of our debt bears interest at floating rates. Therefore, our
liquidity and financial condition is and will continue to be affected by changes
in prevailing interest rates.
 
FOREIGN CURRENCY
 
     The functional currency of the Company's foreign operations acquired in
December 1997 is the local currency. Accordingly, assets and liabilities of
foreign operations are translated to United States dollars at the rates of
exchange in effect on the balance sheet date; income and expense are translated
at the average rates of exchange prevailing during the year. There were no
significant foreign currency transaction gains or losses during 1998 or 1997.
 
SEASONALITY
 
     Historically, the Company has not experienced significant seasonality in
its business. The introduction of trade shows and conferences into the Company's
product mix through the acquisitions of Independent Exhibitions, Ltd. and
Industrial Shows of America in late 1997, and the acquisition of Mecklermedia
Corporation in November 1998, has changed the seasonal pattern of revenue and
profit, as all three companies have pronounced seasonal patterns in their
businesses. The majority of the trade shows owned by Industrial Shows of America
and Mecklermedia Corporation are held in the second and fourth quarters and,
accordingly, the majority of their revenue is recognized in these quarters.
Further, the majority of the Independent Exhibitions, Ltd. shows historically
have been held in the fourth quarter. Accordingly, the Company anticipates that
these acquisitions will have a positive impact on revenue and profit for these
quarters.
 
     The Company may also experience seasonality fluctuations as trade shows and
conferences held in one period in the current year may be held in a different
period in future years.
 
INFLATION
 
     The impact of inflation on the Company's results of operations has not been
significant in recent years.
 
ACCOUNTING CHANGES
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). The Company is required to
adopt this statement in the first quarter of 2000. Management does not believe
this statement will have a material impact on the Company's business, results of
operations or financial condition.
 
EURO CONVERSION
 
     On January 1, 1999, eleven of the 15 participating countries that are
members of the European Union established a new uniform currency known as the
"Euro." The currency existing prior to such date in the participating countries
will be phased out during the transition period commencing January 1, 1999 and
ending January 1, 2002. During such transition period both the Euro and the
existing currency will be available in the participating countries. Although the
Company generates revenues in some of the participating countries, management
does not anticipate that the introduction and use of the Euro will materially
affect Penton's business, results of operations or financial condition.

YEAR 2000

  General
 
     The year 2000 issue is the result of computer programs that were written
using two digits rather than four to define the applicable year. If our computer
programs with date-sensitive functions are not year 2000 compliant, they may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in a system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in similar normal business activities.
 
     Our year 2000 project is proceeding as scheduled. Some of our systems and
related software are already year 2000 compliant, and our project is designed to
bring the remaining software and systems into year 2000 compliance in time to
minimize any significant detrimental effects on operations. Our project covers
information systems infrastructure, financial and administrative systems,
production and circulation operating systems and significant vendors and
customers.
 
  Project
 
     The first component of our project is to identify the internal business
systems and non-information-technology systems of Penton and our operating
subsidiaries that are susceptible to system failures or processing errors as a
result of the year 2000 issue. This effort is substantially complete with all
business systems identified and priorities established for repair or
replacement. Those systems considered most critical to continuing operations are
being given the highest priority.
 
     The second component of our project involves the actual remediation and
replacement of the various business systems. Our company and our operating
subsidiaries are using both internal and external resources to complete this
process. Systems ranked highest in priority have either been remediated or
replaced or scheduled for remediation or replacement including the replacement
of the primary general ledger and accounts payable systems with programs from a
national software vendor. Our objective is to complete substantially all
remediation and replacement of internal systems by July 1999, and to complete
final testing and certification for readiness by the end of the third quarter of
1999.
 
     As part of the second component of our project, significant service
providers, vendors, suppliers and customers that are believed to be critical to
our business operations after January 1, 2000, have been identified and steps
are being taken in an attempt to reasonably ascertain their state of year 2000
readiness through questionnaires, inquiries and other available means. This
process is progressing according to plan.
 
<PAGE>   10
 
  Costs
 
     It is currently estimated that the aggregate incremental cost of our
efforts will range from $0.3 million to $0.8 million, of which about $0.2
million has been spent. These costs are being expensed as they are incurred and
are being funded through operating cash flow. These amounts do not include any
costs associated with the implementation of contingency plans, which are in the
process of being developed to supplement our existing disaster recovery plan.
The costs associated with the replacement of computerized systems, hardware or
equipment is currently estimated to be about $0.5 million, substantially all of
which would be capitalized, and is not included in the above estimates.
 
  Risks
 
     The failure to correct a material year 2000 problem could result in an
interruption in, or a failure of, our normal business activities or operations.
These failures could materially and adversely affect our results of operations,
liquidity and financial condition. Due to the general uncertainty inherent in
the year 2000 problem, resulting in part from the uncertainty of the year 2000
readiness of third-party suppliers and customers, we are unable to determine at
this time whether the consequences of year 2000 failures will have a material
impact on our results of operations, liquidity or financial condition. Our Year
2000 project is expected to significantly reduce our level of uncertainty about
the year 2000 problem and, in particular, about the year 2000 compliance and
readiness of its material external agents. We believe that, with the
implementation of new business systems and completion of our project as
scheduled, the possibility of significant interruptions of normal operations
should be reduced.
 
     Our project readiness program is an ongoing process and the estimates of
costs and completion dates for various components of our project readiness
program described above are subject to change. Based on the company's assessment
and evaluation of its year 2000 readiness, it believes that the most reasonably
likely worst case scenario includes a temporary shut-down of Penton's press. We
estimate that a one-month stoppage of our publishing operations could lead to a
loss of operating income of about $9.4 million.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. 

     The Company's major market risk exposure is due primarily to possible 
fluctuations in interest rates as they relate to its variable rate debt. The 
Company currently has a credit agreement with three components as follows: (1) 
$25 million revolving credit facility which has an interest rate, at the option 
of the Company, of LIBOR plus 2.75% or the Base Rate plus 1.75%; (2) $175.0 
million Term Loan A with the same interest rate as the revolving credit 
facility; and (3) $125.0 million Term Loan B which has an interest rate, at the 
option of the Company, of LIBOR plus 3.50% or the Base Rate plus 2.50%.

     The Company does not enter into derivative financial investments for 
trading or speculation purposes. Overall, the Company believes that its market 
risk exposure is not material to the Company's financial position, liquidity or 
results of operations.

                       REPORT OF INDEPENDENT ACCOUNTANTS
                          

To the Board of Directors of Penton Media, Inc.

In our opinion, the consolidated financial statements and financial statement
schedule as listed in the accompanying index present fairly, in all material
respects, the financial position of Penton Media, Inc. (formerly Penton
Publishing, Inc. and, prior to August 7, 1998, a wholly owned subsidiary of
Pittway Corporation) and its subsidiaries at December 31, 1998, and 1997, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of
Penton Media, Inc.'s management; our responsibility is to express an opinion on
these financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
NATURE OF BUSINESS

Penton Media, Inc., formerly known as Penton Publishing, Inc. ("Penton" or the
"Company") is a business media company that publishes magazines and electronic
media, produces trade shows and conferences, and provides marketing and business
development products and services, including direct mail lists, research and
custom publishing. Penton serves the design/engineering; electronics;
Internet/IT; food/hospitality; government/compliance; leisure; management;
manufacturing; mechanical systems/construction; and supply chain/aviation
markets.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Penton and its
subsidiaries. All significant intercompany accounts and transactions have been
eliminated.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents.

INVENTORIES

Inventories are stated at the lower of cost or market. Costs included in
inventories are raw materials, direct labor and manufacturing overhead. Cost of
substantially all of the paper and ink stock is determined by using the last-in,
first-out (LIFO) method, while the remaining inventories are valued primarily
using the average cost method.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost. The Company records
depreciation, using the straight-line method, in amounts sufficient to write off
the cost of depreciable assets over the following estimated useful lives:

Computer equipment                   3-5 years
Furniture, fixtures and equipment   3-10 years
Buildings                          18-40 years
Leasehold improvements             Estimated useful lives
                                   or lease term,
                                   whichever is shorter

     Depreciation expense amounted to approximately $6.2 million, $5.3 million
and $5.0 million for the years ended December 31, 1998, 1997 and 1996,
respectively.

     Maintenance and repair expenditures are charged to appropriate expense
accounts in the period incurred; replacements, renewals and betterments are
capitalized. Upon sale or other disposition of property, the cost and
accumulated depreciation of such properties are eliminated from the accounts and
the gains or losses thereon are reflected in results of operations.

INTANGIBLE ASSETS

Goodwill, trademarks and trade names acquired in purchase transactions are
amortized using the straight-line method over periods ranging from 20 to 40
years.

     Other intangibles acquired in purchase transactions or developed
internally, consisting of non-compete agreements, customer mailing lists,
exhibitor lists, and patents and copyrights, are being amortized using the
straight-line method over their estimated useful lives ranging from 3 to 15
years. 

     Amortization expense amounted to approximately $4.6 million, $1.3 million
and $0.9 million for the years ended December 31, 1998, 1997 and 1996,
respectively.

     When conditions warrant, the Company reviews the carrying value of its
intangible assets and property and equipment to determine whether an impairment
may exist. The Company considers relevant cash flow, estimated future operating
trends and other available information in assessing whether the carrying value
of these assets can be recovered. In December 1998, the Company wrote down the
carrying value of various intangible assets by $1.0 million, determined using
the expected future cash flows generated from, and market value of, the various
ventures.

DEFERRED FINANCING COSTS

Costs incurred in obtaining long-term financing are included in other intangible
assets in the accompanying balance sheet and are amortized over the terms of the
related debt agreements; such amortization is reflected as amortization expense
in the consolidated statements of income.

REVENUE RECOGNITION

Advertising revenues from the Company's trade magazines are recognized in the
month the publications are mailed. Revenues from trade shows and conferences are
recognized in the month the events are held. Licensing revenues are recognized
on a straight-line basis over the term of the license agreements.

ADVERTISING AND PROMOTION EXPENSES

Advertising and promotion costs are expensed primarily as incurred. These costs
amounted to $12.4 million, $8.4 million and $9.3 million in 1998, 1997 and 1996,
respectively.

                               PENTON MEDIA, INC.

INCOME TAXES

The Company accounts for income taxes in accordance with the provisions of
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" ("SFAS 109"). SFAS 109 requires an asset and liability approach, which
requires the recognition of deferred tax assets and deferred tax liabilities for
the expected future tax consequences of temporary differences between the
carrying amounts and the tax bases of assets and liabilities. Valuation
allowances are established when necessary to reduce deferred tax assets to the
amount expected to be realized.

     For periods prior to and including the date of the spinoff (see Note 2),
the results of the Company were included in Pittway Corporation's consolidated
U.S. federal income tax returns. The provision for income taxes included in the
consolidated statements of income represented an allocated share of Pittway's
tax expense. The allocated share approximated the tax expense that would have
been incurred on a separate return basis. The liability for income taxes payable
at December 31, 1997, was recorded by Pittway.

     Pursuant to the Combination Agreement (see Note 2), the Company is required
to indemnify Pittway for any additional federal, state, local and foreign income
tax liabilities with respect to all periods prior to and including the date of
the spinoff. All consolidated federal income tax returns of Pittway have been
audited by the Internal Revenue Service through 1995.

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 reported amounts of assets and liabilities and the reported amounts
of revenues and expenses during the reporting period. Actual results could
differ from those estimates.

TRANSLATION OF FOREIGN CURRENCIES

The functional currency of the Company's foreign operations is the local
currency. Accordingly, assets and liabilities of foreign operations are
translated to U.S. dollars at the rates of exchange in effect on the balance
sheet at December 31, 1998; income and expense are translated at the average
rates of exchange prevailing during the year. There were no transaction gains or
losses in 1998 and 1997.

NET INCOME PER SHARE

The weighted average number of common shares outstanding is adjusted for common
stock equivalents when they are dilutive.

RECLASSIFICATIONS

Certain reclassifications have been made to the 1997 and 1996 financial
statements to conform to the 1998 presentation.

CHANGE IN ACCOUNTING ESTIMATE

Effective October 1, 1998, the Company changed its estimated useful life on
goodwill associated with trade show acquisitions from 40 to 20 years. The change
decreased 1998 net income by $0.3 million, or $0.01 per share. The estimated
effect of the change on future years will be to decrease income by $1.2 million.
The change was made to better reflect the estimated useful life of goodwill and
to be consistent with prevalent industry practice.

NEW ACCOUNTING STANDARDS

The Company does not believe any recently issued accounting standards will have
a material impact on its financial condition or results of operations.

NOTE 2 - SPINOFF FROM PITTWAY AND
SUBSEQUENT ACQUISITION

Prior to August 7, 1998, Penton was a wholly owned subsidiary of Pittway
Corporation. On August 7, 1998, Pittway distributed 100% of the Company's common
stock on a share-for-share basis to holders of Pittway stock.

     Immediately after the spinoff, the Company entered into an agreement (the
"Combination Agreement") and completed the acquisition of Donohue/Meehan
Publishing Company ("DM Publishing"). DM Publishing was acquired for $7.0
million in cash, 6.767% (1,541,638 shares) of the Company's stock to be
outstanding immediately after the acquisition and up to an additional $4.0
million in cash based on DM Publishing's pre-tax income for the years 1998 and
1999, of which $2.0 million was earned in 1998. The Company also has agreed to
make a contingent cash payment to the extent, if any, that the shares issued in
the acquisition have an average aggregate market value of less than $29.0
million during either of two 30-day periods in the year 2000. The contingent
payment is subject to certain limitations as to any of such shares sold prior to
the payment. A portion of the contingent payment may be made with common stock
rather than cash under certain conditions.

     The transaction was accounted for as a purchase and, accordingly, the
operating results of DM Publishing have been included in the Company's
consolidated financial statements since the date of acquisition. The excess of
the aggregate purchase price over the fair market value of net assets acquired
of approximately $32.4 million is being amortized over 40 years.

NOTE 3 - ACQUISITIONS AND DISPOSITIONS

In addition to the acquisition of DM Publishing, the Company, pursuant to an
Agreement and Plan of Merger, completed its cash tender offer for all of the
outstanding shares of Mecklermedia Corporation ("Mecklermedia") on November 24,
1998. In connection with the acquisition, each Mecklermedia shareholder received
$29.00 in cash for each share of common stock owned. The total value of the
transaction was $273.8 million, and it was funded with the net proceeds
available from the credit agreement dated November 24, 1998 (see Note 6). The
transaction was accounted for as a purchase and, accordingly, the operating
results of Mecklermedia have been included in the Company's consolidated
financial statements since the date of acquisition. The excess of the aggregate
purchase price over the fair market value of net assets acquired of
approximately $242.5 million is being amortized over 20 years.

     During 1997, the Company acquired one foreign and two domestic trade show
companies for $45.6 million in cash and $2.5 million of notes payable to the
sellers. The acquisitions also include future contingent payments up to $13.5
million tied to future earnings of the acquired companies through the year 2000,
of which $2.4 million and $0.7 million were earned in 1998 and 1997,
respectively.

     In 1997, the Company also sold one publication for $1.0 million and the
assumption of certain liabilities.

     All the aforementioned acquisitions were accounted for as purchase
transactions. These operations have been included in the consolidated financial
statements from their respective dates of acquisition or to the dates of
disposition.

     The following unaudited supplemental pro forma information is presented to
reflect the effects of the issuance of common stock pursuant to the spinoff from
Pittway and the DM Publishing acquisition, the Mecklermedia acquisition, and the
1997 acquisitions and dispositions, as if all such transactions had occurred on
January 1, 1997.

     The pro forma financial information is presented for informational purposes
only, and may not be indicative of what actual results of operations would have
been had the acquisitions occurred as indicated; nor does it purport to
represent the results of the operations for future periods. (Dollars in

NOTE 4 - INVENTORIES

The LIFO reserve balances of $0.4 million and $0.5 million at December 31, 1998,
and 1997, respectively, represent the excess of current replacement cost over
the LIFO value of inventory, which consists principally of raw materials.

NOTE 5 - EQUITY INVESTMENTS IN JOINT VENTURES

Penton, in November 1998, entered into a joint venture agreement with Alan M.
Meckler, Mecklermedia's founder, with respect to the limited liability company
Internet.com. Internet.com is a network of Web sites that provides news,
analysis and information resources for Internet professionals. Penton sold an
80.1% equity interest in Internet.com to Mr. Meckler for $18.0 million,
retaining 19.9% of the equity and warrants to acquire up to a 29.9% interest. At
December 31, 1998, the Company's investment in Internet.com was $4.5 million.
Internet.com and Penton also entered into various agreements relating to the
exchange of services between the two companies.

NOTE 6 - DEBT

CREDIT AGREEMENT

     On November 24, 1998, the Company entered into a credit agreement with
several banks under which it may borrow up to $325.0 million. The agreement
provides for a revolving loan facility of up to $25.0 million, a long-term loan
of $175.0 million (Term A Loan) and a long-term loan of $125.0 million (Term B
Loan). The proceeds of the new facility were used to repay the Company's debt
outstanding under a $75.0 million revolving credit facility obtained at the
spinoff date and to purchase Mecklermedia.

     The credit facility is collateralized by receivables, inventories,
equipment and certain real and personal property. Under the terms of the
agreement, the Company is required to maintain certain financial ratios and
other financial conditions. The agreement also prohibits the Company from
incurring certain additional indebtedness; limits certain investments, advances
or loans; and restricts substantial asset sales, capital expenditures and cash
dividends. At December 31, 1998, the Company was in compliance with all loan
covenants.

     The revolving loan facility includes a revolving loan and a swing loan. The
revolving loan requires payment of interest (only) at a Base Rate (determined as
the higher of the Prime Rate or the Federal Funds Effective Rate plus 1/2 of 1%)
or an Adjusted Eurodollar Rate, at the Company's option, plus a rate margin
ranging from 1.25% to 3.0% based on the Company's consolidated leverage ratio,
as defined. At December 31, 1998, the rate on the revolving loan was 9.5%.


<PAGE>   21
                               PENTON MEDIA, INC.

     The swing loan, which permits borrowings up to $5.0 million, requires
payment of interest (only) at the Base Rate plus a Base Rate margin ranging from
1.25% to 2.00% based on the Company's consolidated leverage ratio, as defined,
less the applicable commitment fee percentage per annum. At December 31, 1998,
no amounts were drawn on the swing loan facility.

     The Company has agreed to pay a commitment fee of 0.50% on the unused
portion of the revolving loan facility commitment. At December 31, 1998, $19
million was available under the facility.

     The Term A Loan bears interest at the Base Rate or at an Adjusted
Eurodollar Rate, at the Company's option, plus a rate margin ranging from 1.25%
to 3.0% based on the Company's consolidated leverage ratio, as defined. Interest
is payable monthly; at December 31, 1998, the rate in effect was 7.79%. The
loan, which requires quarterly principal payments of $2.5 million starting in
March 1999, will mature on June 30, 2005. At December 31, 1998, $175.0 million
was outstanding under the Term A Loan.

     The Term B Loan bears interest at the Base Rate plus 2.5% or at the
Adjusted Eurodollar Rate plus 3.5%, at the Company's option. Interest is payable
monthly; at December 31, 1998, the rate in effect was 8.54%. The loan, which
requires quarterly principal payments of $0.3 million starting on March 31,
1999, and a balloon payment at maturity, will mature on May 31, 2005. At
December 31, 1998, $125.0 million was outstanding under the Term B Loan.

     As of December 31, 1998, the scheduled principal payments of the Term A
Loan and Term B Loan for the next five years and thereafter are as follows (in
thousands):

</TABLE>

     The credit agreement requires the Company to hedge not less than 50% of the
Term A Loan outstanding with a fixed interest rate agreement for a term of not
less than two years.

NOTE PAYABLE

The short-term note payable at December 31, 1998, of $1.0 million represented
foreign indebtedness, was denominated in British pounds and bore interest at the
Company's foreign borrowing rate (8.2% at December 31, 1998). The note, plus
accrued interest, was paid off in early January 1999.

     The Company's short-term notes payable at December 31, 1997, included $29.2
million of foreign indebtedness denominated in British pounds and bearing
interest at 8.1%, and $5.0 million of domestic indebtedness at 6%. Concurrent
with the spinoff from Pittway, $27.8 million of foreign debt, including accrued
interest and the $5.0 million domestic debt, was refinanced with the $75.0
million revolving credit facility.

     There are no compensating balance or commitment fee requirements associated
with these short-term borrowings.

NOTE 7 - FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amount of accounts and notes receivable, accounts payable,
accrued expenses and notes payable approximates fair value because of the short
maturity of these instruments.

     The carrying amount of the Company's borrowing under its senior debt
facility and revolving credit facility approximates fair value because such
borrowings are at variable rates. The Company may, from time to time, enter into
interest rate hedge agreements to manage interest costs and risks associated
with changing interest rates.

NOTE 9 - RETIREMENT PLAN

The Company has various non-contributory retirement plans covering substantially
all current and former domestic employees. Retirement benefits for employees in
foreign countries are generally provided by national statutory programs.
Benefits for domestic employees are based on years of service and annual
compensation as defined by each plan. All employees received credit for their
years of service in the Pittway plan. Prior to 1995, Pittway allocated net
pension plan income credits to the Company based upon the assets of a previously
separate Company plan, which was merged into the Pittway plan in 1991. At the
time the plans were merged, the amount of the Company's plan assets exceeded its
projected benefit obligation and, by 1995, such excess ("Funding Excess") had
increased and had become substantially disproportionate to the Funding Excess
for the remainder of the Pittway plan. As a result, for the years 1996 and 1997,
Pittway limited the allocation of net pension income credits to the Company to
$1.5 million per year.

     As provided in the Combination Agreement, Pittway transferred $45.0 million
of its plan assets ("Allocated Assets"), including approximately $10.5 million
of Funding Excess as of December 31, 1997, to the new Penton plan. The amount of
Allocated Assets was determined by Pittway as the estimated proportion of total
Pittway plan assets that would result in the elimination of the Funding Excess
for the Company in the same future year as such elimination for the remainder of
the Pittway plan based on historical rates of service cost increases and return
on plan assets. 

     The "Net deferred pension credits" in the consolidated balance sheet at
December 31, 1997, includes deferred investment gains of $29.5 million, which
Pittway allocated to the Company on a basis consistent with the above-mentioned
limitation on previous net pension plan income credits.

     The reconciliation of the funded status of the Company's portion of the
plan follows (in thousands):

NOTE 10 - BENEFIT PLANS

STOCK OPTION AND OTHER EQUITY-BASED PLANS

Effective August 1998, the Company established a stock option plan under which
the Company may issue qualified incentive stock options to key employees,
including officers, up to an aggregate of 2,500,000 shares of common stock.
Awards may be issued in the form of options to purchase shares of common stock,
stock appreciation rights ("SARs"), restricted shares, deferred shares,
performance shares and performance units. In 1998, 700,452 shares were granted
under the Equity and Incentive Plan, of which 686,055 were stock options and
14,397 were deferred shares. Options granted under the plan generally become
exercisable in the year after the date of grant as to one-third of the optioned
shares, with the remaining options being exercisable over the following two-year
period. Included in the stock options issued during 1998 are 47,655
non-qualified shares, which represent the conversion of the Chief Executive
Officer's non-qualified Pittway options for an equal value of Penton options.
These options vest 50% in 1999 and 50% in 2000. As of December 31, 1998, no
shares were exercisable. The option price of all options granted was $16.23.

     As noted above, 14,397 deferred shares were issued in 1998. These shares
become vested between one and three years. The Board of Directors of the Company
may authorize the payment of dividend equivalents on such shares on a current,
deferred or contingent basis, either in cash or additional shares of common
stock. At December 31, 1998, no such authorization had been made.

     In addition to the stock option plan described above, the Company granted
options for a total of 69,000 shares to its directors who are not employees of
the Company. Such options were granted at the fair market value on the date of
grant. Options with respect to 13,000 shares were exercisable immediately after
grant, and options with respect to the remaining 56,000 shares become
exercisable one year after the date of grant as to one-fourth of the 56,000
shares, with the remaining options being exercisable over the following
three-year period. The option price at the date of grant was $16.23.

     The following table reflects the stock option activity described above (in
thousands):

</TABLE>

     The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model, with the following assumptions used for
grants in 1998: risk-free interest rate of 5.4%; expected lives ranging from 8.0
to 10.0 years; expected dividend rate of 0.3%; and expected volatility of 70.6%.

     The Company applies Accounting Principles Board Opinion No. 25 in
accounting for its stock option plans. Accordingly, no compensation expense has
been recognized for its stock option plans. If compensation expense had been
determined in accordance with Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation," net income would have been
reduced by $0.9 million in 1998 and basic and diluted earnings per share would
have been reduced by $0.04.

401(k) PLAN

Effective September 1, 1998, the Company adopted a 401(k) defined contribution
plan ("Plan") covering substantially all of the officers and employees of the
Company. The Combination Agreement provided for a transfer of assets and
liabilities attributable to Penton employees in the Pittway 401(k) plan to be
transferred to this Plan. The Plan permits participants to defer up to a maximum
of 15% of their compensation. The Company will match 50% of an employee's
contributions up to a maximum of 6% of an employee's annual compensation. The
employees' contribution and the Company's matching contribution vest
immediately. The Company's contribution to the Plan for the year ended December
31, 1998, was $0.4 million. The 401(k) plan was fully funded at December 31,
1998.

SERP

Two executive officers participate in the Company's supplemental executive
retirement plan, which is not tax-qualified. At December 31, 1998, the estimated
annual benefit payable under the plan upon retirement at age 65 was $0.1 million
for both participants, assuming a life expectancy of 80 years and a discount
rate of 7%. At December 31, 1998, $0.03 million was accrued related to this
future obligation, and $0.02 million of expense was recognized in 1998,
representing service costs and interest.

NOTE 11 - COMMITMENTS AND CONTINGENCIES

The Company leases certain office space and equipment under non-cancelable
operating leases. Some of the leases contain renewal options and certain
equipment leases include options to purchase during or at the end of the lease
term. The following is a schedule of approximate future annual minimum rental
payments required under operating leases that have initial or remaining
non-cancelable lease terms in excess of one year as of December 31, 1998 (in

</TABLE>
     For the years ended December 31, 1998, 1997 and 1996, the total rent
expense (including taxes, insurance and maintenance when included in the rent)
incurred by the Company was approximately $6.5 million, $6.6 million and $6.3
million, respectively.

     The Company has employment agreements with six key employees for terms of
two years, and the ability to extend for additional one-year periods.

     In connection with the acquisition of Mecklermedia, a lawsuit was brought
against the Company by a former shareholder of Mecklermedia for an unspecified
amount, as well as other relief. The plaintiff is claiming that the Company
violated the federal securities laws by selling Mr. Meckler an 80.1% interest in
Internet.com for what the plaintiff alleges was a below-market price, thereby
giving to Mr. Meckler more consideration for his common stock in Mecklermedia
than was paid to the other stockholders of Mecklermedia. The Company believes
that the allegations are without merit and has filed a motion to dismiss the
lawsuit, which is pending.

     The Company in the normal course of business is subject to a number of
lawsuits and claims, both actual and potential in nature. While management
believes that resolution of existing claims and lawsuits will not have a
material adverse effect on the Company's financial statements, management is
unable to estimate the magnitude of financial impact of claims and lawsuits that
may be filed in the future.

NOTE 12 - RELATED PARTY TRANSACTIONS

The Combination Agreement provides for Pittway to assist Penton in preparing its
tax returns for 1998 and to assist in other tax matters for fees to be
negotiated.

     Included in the consolidated statements of income is an allocation of
corporate expenses related to services provided for the Company by Pittway. This
allocation was based on an estimate of the incremental corporate expenses
related to the Company's operations for the periods presented and, in the
opinion of management, has been made on a reasonable basis. However, the
allocation is not necessarily indicative of the level of expenses that might
have been incurred had the Company been a separate company. The aggregate
allocated costs totaled $0.3 million, $0.4 million and $0.3 million for the
years ended 1998, 1997 and 1996, respectively. The Company's employees also
participated in Pittway's pension plan (see Note 9). Certain of the Company's
employees participated in Pittway's 1990 Stock Awards Plan, for which Pittway
has allocated costs to the Company totaling $1.2 million, $1.0 million and $1.1
million in 1998, 1997 and 1996, respectively.

     Other transactions between the Company and Pittway, consisting principally
of taxes and other reimbursable expenses paid by Pittway, have been reflected in
the historical financial statements as though on a stand-alone basis, except
that no interest income or expense has been allocated on intercompany balances.

     Pittway utilized a centralized cash management system. Under this system,
cash generated by Penton in excess of its cash requirements (including cash
requirements for Penton's income taxes and other reimbursable expenses paid by
Pittway) was transferred to Pittway and reflected as "Due from parent company"
in the balance sheet. This account was reduced by dividends declared by the
Company. In August 1998, a final non-cash dividend of $12.2 million was made to
Pittway to settle the "Due from parent company" account.

NOTE 13 - CAPITAL STOCK

Pursuant to the spinoff (see Note 2), the Company amended its certificate of
incorporation on June 4, 1998, to authorize capital stock consisting of 60
million shares of common stock, par value $0.01 per share, and 2 million shares
of preferred stock, par value $0.01 per share. Immediately thereafter, the
Company recapitalized the 1,000 shares of $1 par value common stock outstanding
into 21,240,000 shares of common stock. An amount of $211 was transferred from
capital in excess of par value to common stock. The financial statements and
related notes have been restated to reflect this recapitalization retroactively.

In connection with the DM Publishing acquisition (see Note 2), 1,541,638 
shares were issued as partial consideration.

NOTE 14 - EARNINGS PER SHARE

Effective December 31, 1997, the Company adopted the provisions of Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"), which
requires the replacement of primary and fully diluted earnings per share with
basic and diluted earnings per share, respectively. SFAS 128 also requires
restatement of previously reported earnings per share information for certain
periods presented in the accompanying statement of income to ensure consistency
with currently reported amounts. 

     Computations of basic and diluted earnings per share for the years ended
December 31, 1998, 1997 and 1996 are shown in Table 1.

     Options to purchase 750,055 shares of common stock at $16.23 per share were
outstanding at December 31, 1998, but were not included in the computation of
diluted earnings per share because the average market value of the options was
below the exercise price.

NOTE 15 - SEGMENT INFORMATION

As indicated in Table 2 below, the Company has three reportable segments:
Media Services, Printing and Direct Mail. The segments are based on the
Company's internal organization and are managed separately due to inherent
differences in the nature of these businesses. Within the Media Services
segment, operating segments serving differing industries were combined due to
the similarity of their economic characteristics and other factors.

     The Media Services segment serves specific industries and broad markets
with integrated product offerings including trade magazines, trade shows and
conferences, directories, direct mail lists and a variety of other products and
services. Revenues of this segment are generated primarily from magazine
advertising and trade show booth rentals. The Printing segment prints magazines,
catalogs, brochures and direct mail pieces for the Media Services segment and
outside commercial customers. The Direct

                               PENTON MEDIA, INC.

Mail segment serves primarily the pharmaceutical and business services markets
with the ability to design, produce, print and mail direct mail marketing
campaigns. The $1.0 million impairment charge relates principally to this
segment.

     Intersegment revenues are made at approximate arm's-length prices. The
Company evaluates performance based on operating income. Segment assets are
those assets that are specifically identified with the reportable segments in
which operations are conducted. Non-current assets at December 31, 1998, and
1997 included $31.7 million and $30.0 million, respectively, identified with
operations in the United Kingdom, substantially all of which are intangible
assets, with the remaining assets identified with domestic operations.
Non-current assets at December 31, 1996, were domestic. Export sales were not
material and no single customer accounted for 10% or more of sales.

                          RESTATED EMPLOYMENT AGREEMENT
                          -----------------------------


                  This RESTATED EMPLOYMENT AGREEMENT ("Agreement") effective as
of January 1, 1999, between Penton Media, Inc. (formerly known as Penton
Publishing, Inc.), a Delaware corporation (the "COMPANY"), and Thomas L. Kemp
("EXECUTIVE").

                                   WITNESSETH:

                  WHEREAS, Executive is presently the Chief Executive Officer of
the Company and has made and is expected to continue to make major contributions
to the profitability, growth and financial strength of the Company;

                  WHEREAS, the Company recognizes that, as is the case with many
publicly held companies, the possibility of a Change of Control (as that term is
hereafter defined) exists;

                  WHEREAS, the Company wishes to assure itself of both present
and future continuity of management in the event of any Change of Control;

                  WHEREAS, the Company wishes to ensure that certain of its
executives are not practically disabled from discharging their duties upon a
Change of Control; and

                  WHEREAS, the Company and Executive currently are parties to an
Employment Agreement (the "PRIOR AGREEMENT") providing certain benefits, and the
Company and Executive desire to amend and restate the Prior Agreement;

                  NOW, THEREFORE, in consideration of the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

                  1. EMPLOYMENT. The Company shall employ Executive, and
Executive accepts continued employment with the Company as of the date hereof,
upon the terms and conditions set forth in this Agreement for the period
beginning on the date hereof and ending as provided in paragraph 5 hereof (the
"EMPLOYMENT PERIOD").

                  2. POSITION AND DUTIES.

                  (a) During the Employment Period, Executive shall serve as the
chief executive officer of the Company and, subject to the management of the
business and affairs of the Company at the direction of the Board of Directors
of the Company (the "BOARD"), shall have the normal duties, responsibilities and
authority of an executive serving in such position, including without limitation
the development of short- and long-term operating plans, the development of
operating and capital budgets, the overseeing of Company personnel and the
development of compensation proposals and proposals for acquisitions and
dispositions. Executive shall have the title Chief Executive Officer of the
Company, subject to the power of the Board to change such title to President and
Chief Executive Officer or some combination thereof. During the Employment
Period, Executive shall also serve as a director of the Company for so long as
the Board (or a


<PAGE>   2



nominating committee of the Board) nominates him to that position and he is
elected to it and as a director of any affiliate of the Company designated by
the Board for so long as the Board causes him to be elected to such position.

                  (b) Executive shall report to the Board.

                  (c) During the Employment Period, Executive shall devote his
best efforts and his full business time and attention (except for permitted
vacation periods, reasonable periods of illness or other incapacity, and,
provided such activities do not have more than a DE MINIMIS effect on
Executive's performance of his duties under this Agreement, participation in
charitable and civic endeavors and management of Executive's personal
investments and business interests) to the business and affairs of the Company,
its subsidiaries and affiliates. Executive shall perform his duties and
responsibilities to the best of his abilities in a diligent, trustworthy,
businesslike and efficient manner.

                  (d) Executive shall perform his duties and responsibilities
principally in the Cleveland, Ohio metropolitan area, and shall not be required
to travel outside that area any more extensively than he has done in the past in
the ordinary course of the business of the Company.

                  3. COMPENSATION AND BENEFITS.

                  (a) SALARY. The Company agrees to pay Executive a salary
during the Employment Period in monthly installments. Executive's initial salary
shall be $470,000 per year. The Compensation Committee of the Board (or, if
there is no such Committee, the Board) shall review Executive's salary from time
to time and may, in its sole discretion, increase it.

                  (b) BONUS(ES). Effective January 1, 1999 and for subsequent
years, Executive will be eligible for an annual bonus (the "Target Bonus") based
on the achievement of specified Company goals (as determined by the Compensation
Committee of the Board (or, if there is no such Committee, the Board) with input
from Executive). Any bonus payable pursuant to this subparagraph (b) may, at the
discretion of the Compensation Committee of the Board (or, if there is no such
Committee, the Board), after considering any preference expressed by Executive,
be paid in the form of cash, in a Performance Shares Award related to shares of
the Company's Common Stock or in a combination of both.

                  (c) STOCK OPTIONS. The Company has adopted a plan (the "1998
STOCK OPTION PLAN") pursuant to which options to purchase shares of the
Company's Common Stock, and other equity-based incentive compensation awards,
may be granted to Executive and other officers of the Company. Executive shall
be eligible to receive grants of options and other awards under the 1998 Stock
Option Plan, at the discretion of the Compensation Committee of the Board (or,
if there is no such Committee, the Board). Under the terms of the 1998 Stock
Option Plan, the Compensation Committee of the Board (or, if there is no such
Committee, the Board) has the right to amend the 1998 Stock Option Plan. If, at
the time of the grant of any option pursuant to this paragraph (c), the issuance
of shares upon exercise thereof has not been registered under the Securities Act
of 1933, as amended, it shall be a condition to such grant that Executive
execute and deliver to the Company a certificate confirming that Executive is an
accredited investor (as such term is used in Regulation D under such Act) and
including transfer restrictions and other provisions customary in connection
with grants under such circumstances. Each option to be granted as set forth
above shall be substantially in the form of EXHIBIT 1 attached to this
Agreement, except that it is understood that


<PAGE>   3



reference to any then existing registration statement or related plan
information document in EXHIBIT 1, or its equivalent, shall be included if and
only if the same exists at the time of grant and is relevant to such option.

                  (d) EXPENSE REIMBURSEMENT. The Company shall reimburse
Executive for all reasonable expenses incurred by him during the Employment
Period in the course of performing his duties under this Agreement that are
consistent with the Company's policies in effect from time to time with respect
to travel, entertainment and other business expenses, subject to the Company's
requirements applicable generally with respect to reporting and documentation of
such expenses. Executive acknowledges that under the Company's current air
travel reimbursement policy, reimbursement is limited to coach fare (plus
Executive's cost of any upgrade certificates used to upgrade to first class) on
travel within the United States and is limited to business class fare on travel
to and from foreign cities.

                  (e) STANDARD EXECUTIVE BENEFITS PACKAGE. In addition to the
salary, bonus(es), stock options and expense reimbursements payable to Executive
pursuant to this paragraph 3, Executive shall be entitled during the Employment
Period to participate, on the same basis as other executives of the Company, in
the Company's Standard Executive Benefits Package. The Company's "STANDARD
EXECUTIVE BENEFITS PACKAGE" means those benefits (including insurance, vacation,
Company car or car allowance, equity-based benefits, and other benefits) for
which substantially all of the executives of the Company are from time to time
generally eligible, as determined from time to time by the Board. Without
limiting the generality of the foregoing, Executive and the Company acknowledge
and agree that, for purposes of vacation benefits included in the Standard
Executive Benefits Package, Executive has been credited with 22 years of service
in addition to his actual period of service with the Company.

                  (f) ADDITIONAL BENEFITS. In addition to participation in the
Company's Standard Executive Benefits Package pursuant to this paragraph,
Executive shall be entitled during the Employment Period to:

                  (i)      additional term life insurance coverage in an amount
                           equal to Executive's salary, but only if and so long
                           as such additional coverage is available at standard
                           rates from the insurer providing term life insurance
                           coverage under the Standard Executive Benefits
                           Package or from a comparable insurer acceptable to
                           the Company;

                  (ii)     supplementary long-term disability coverage in an
                           amount that will include maximum covered annual
                           compensation of $330,000 and maximum monthly payments
                           of $18,333, but only if and so long as such
                           supplementary coverage is available at standard rates
                           from the insurer providing long-term disability
                           coverage under the Standard Executive Benefits
                           Package or a comparable insurer acceptable to the
                           Company;

                  (iii)    in the event the Employment Period ends at a time
                           when Executive is not entitled to all of the benefits
                           under the tax-qualified pension plan and
                           tax-qualified defined contribution plan (401(k) plan)
                           of the Company included in the Standard Executive
                           Benefits Package to which he would have been entitled
                           had he been fully vested under such plans at the
                           beginning of the Employment Period, a supplemental
                           payment (independent of any plan)


<PAGE>   4



                           promptly following the end of the Employment Period
                           equal to the sum of (A) the discounted present value
                           of his accrued but unvested future payments (on a
                           straight life basis) under such pension plan,
                           calculated using the discount rate and actuarial
                           methods and procedures then utilized under such plan
                           and (B) the unvested portion of his account under
                           such defined contribution plan; and

                  (iv)     pursuant to authorization by the Compensation
                           Committee of the Board (or, if there is no such
                           Committee, the Board), participation in the Penton
                           Media, Inc. Supplemental Executive Retirement Plan
                           (the "SERP"), effective August 7, 1998, as currently
                           in effect, except that (A) the beginning date for
                           accrual of a benefit shall be the date on which
                           Executive's employment with the Company began and (B)
                           no benefit shall be payable thereunder unless the
                           Employment Period shall end five years or more after
                           the beginning thereof (or, if the Employment Period
                           ends early pursuant to paragraph 5 hereof, within
                           such five years on account of a Termination without
                           Cause, a Termination by Executive for Good Reason or
                           a Termination Following a Change of Control, provided
                           that the date on which (without any extension
                           thereof) the Employment Period is then scheduled to
                           end shall be five years or more after the beginning
                           of the Employment Period).

                  (g) INDEMNIFICATION. With respect to Executive's acts or
failures to act during the Employment Period in his capacity as a director,
officer, employee or agent of the Company, Executive shall be entitled to
indemnification from the Company, and to liability insurance coverage (if any),
on the same basis as other directors and officers of the Company.

                  4. ADJUSTMENTS. Notwithstanding any other provision of this
Agreement, it is expressly understood and agreed that if there is a significant
reduction in the level of the business to which Executive's duties under this
Agreement relate, the Compensation Committee of the Board (or, if there is no
such Committee, the Board) may make adjustments in "EXECUTIVE'S REFERENCE
SALARY" (i.e., Executive's initial salary or, in the event the Employment Period
has been extended pursuant to paragraph 5(b) hereof, Executive's salary on the
date on which the most recent such extension occurred) as the Compensation
Committee of the Board (or, if there is no such Committee, the Board) deems
appropriate to reflect such reduction.

                  5. EMPLOYMENT PERIOD.

                  (a) Except as hereinafter provided, the Employment Period
shall continue until, and shall end upon, the third anniversary of the date on
which the Employment Period begins.

                  (b) On each anniversary of the date on which the Employment
Period begins which precedes Executive's sixty-fifth birthday by more than two
years, unless the Employment Period shall have ended early pursuant to (c) below
or either party shall have given the other party written notice that the
extension provision in this sentence shall no longer apply, the Employment
Period shall be extended for an additional year (unless Executive's sixty-fifth
birthday occurs during such additional year, in which event the Employment
Period shall be extended only until such birthday). In no event shall the
Employment Period be extended beyond Executive's sixty-fifth birthday except by
mutual written agreement of the Company and Executive.

                  (c) Notwithstanding (a) and (b) above, the Employment Period
shall end early upon the first to occur of any of the following events:

                  (i)      Executive's death;

                  (ii)     Executive's retirement upon or after reaching age 65

                  (iii)    the Company's termination of Executive's employment
                           on account of Executive's having become unable (as
                           determined by the Board in good faith) to regularly
                           perform his duties hereunder by reason of illness or
                           incapacity for a period of more than six (6)
                           consecutive months ("TERMINATION FOR DISABILITY");

                  (iv)     the Company's termination of Executive's employment

                  (v)      the Company's termination of Executive's employment
                           other than a Termination for Disability or a
                           Termination for Cause ("TERMINATION WITHOUT CAUSE");

                  (vi)     Executive's termination of Executive's employment for
                           Good Reason by means of advance written notice to the
                           Company at least thirty (30) days prior to the
                           effective date of such termination identifying such
                           termination as a Termination by Executive for Good
                           Reason and identifying the Good Reason ("TERMINATION
                           BY EXECUTIVE FOR GOOD REASON") (it being expressly
                           understood that Executive's giving notice that the
                           extension provision in the first sentence of
                           paragraph 5(b) hereof shall no longer apply shall not
                           constitute a Termination by Executive for Good
                           Reason);

                  (vii)    Executive's termination of Executive's employment for
                           any reason other than Good Reason, by means of
                           advance written notice to the Company at least one
                           hundred twenty (120) days prior to the effective date
                           of such termination identifying such termination as a
                           Termination by Executive with Advance Notice
                           ("TERMINATION BY EXECUTIVE WITH ADVANCE NOTICE") (it
                           being expressly understood that Executive's giving

                  (v)      gross negligence or willful misconduct by Executive

                           Termination by Executive for Good Reason or a
                           Termination by Executive with Advance Notice shall

                  (vii)    breach by Executive of any of the agreements in
                           paragraph 8 hereof prior to the end of the Employment
                           Period; or

                  (viii)   any other breach by Executive of this Agreement which

                           days after written notice thereof to Executive from
                           the Company.

                  (ix)     Notwithstanding the foregoing, Executive shall in no
                           event be deemed to have been terminated for "Cause"
                           hereunder unless prior to his termination there shall
                           have been delivered to Executive a copy of a
                           resolution duly adopted by the affirmative vote of
                           not less than a majority of the non- employee
                           Directors then in office at a meeting of the Board
                           called and held for such purpose, after reasonable
                           notice to Executive and an opportunity for Executive,
                           together with Executive's counsel (if Executive
                           chooses to have counsel present at such meeting), to
                           be heard before the Board, finding that, in the good
                           faith opinion of the Board, Executive had committed
                           an act constituting "Cause" as herein defined and
                           specifying the particulars thereof in detail. While
                           such a determination will be a condition precedent
                           for the existence of "Cause" for purposes of this
                           Agreement, such a determination will not be
                           determinative or create a presumption that "Cause" in
                           fact exists and nothing herein will limit the right
                           of Executive or his beneficiaries to contest the
                           validity or propriety of any such determination.

                  (e)      For purposes of this Agreement, "GOOD REASON" shall
                           mean:

                  (i)      any downward adjustment by the Board in Executive's
                           Reference Salary pursuant to paragraph 4 hereof or
                           any downward adjustment by the Board in Executive's
                           Target Bonus; or

                  (ii)     the Company's giving notice that the extension
                           provision in the first sentence of paragraph 5(b)
                           hereof shall no longer apply; or

                  (iii)    any breach by the Company of this Agreement which is
                           material and which is not cured within thirty (30)
                           days after written notice thereof to the Company from
                           Executive.

                  (f) For purposes of this Agreement, "CHANGE OF CONTROL" shall
mean the occurrence of any of the following events during the Employment Period:

         the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
         Act of 1934, as amended (the "Exchange Act")) (a "Person") of
         beneficial ownership (within the meaning of Rule 13d-3 promulgated
         under the Exchange Act) of 40% or more of either: (A) the
         then-outstanding shares of common stock of the Company (the "Company
         Common Stock") or (B) the combined voting power of the then-outstanding
         voting securities of the Company entitled to vote generally in the
         election of directors ("Voting Stock"); PROVIDED, HOWEVER, that for
         purposes of this subparagraph (i), the following acquisitions shall not
         constitute a Change of Control: (A) any acquisition directly from the
         Company, (B) any acquisition by the Company, a subsidiary of the
         Company or the Harris Group, (C) any acquisition by any employee
         benefit plan (or related trust) sponsored or maintained by the Company
         or any subsidiary of the Company, or (D) any acquisition by any Person
         pursuant to a transaction which complies with clauses (A), (B) and (C)

                  (ii) Individuals who, as of the date hereof, constitute the
         Board (the "Incumbent Board") cease for any reason (other than death or

         hereof whose election, or nomination for election by the Company's
         shareholders, was approved by a vote of at least a majority of the
         directors then comprising the Incumbent Board (either by a specific
         vote or by approval of the proxy statement of the Company in which such
         person is named as a nominee for director, without objection to such
         nomination) shall be considered as though such individual were a member
         of the Incumbent Board, but excluding for this purpose, any such
         individual whose initial assumption of office occurs as a result of an
         actual or threatened election contest (within the meaning of Rule
         14a-11 of the Exchange Act) with respect to the election or removal of
         directors or other actual or threatened solicitation of proxies or
         consents by or on behalf of a Person other than the Board; or

                  (iii) Consummation of a reorganization, merger or
         consolidation or sale or other disposition of all or substantially all
         of the assets of the Company (a "Business Combination"), in each case,
         unless, following such Business Combination, (A) all or substantially
         all of the individuals and entities who were the beneficial owners,
         respectively, of the Company Common Stock and Voting Stock immediately
         prior to such Business Combination beneficially own, directly or
         indirectly, more than a majority of, respectively, the then-outstanding
         shares of common stock and the combined voting power of the
         then-outstanding voting securities entitled to vote generally in the
         election of directors, as the case may be, of the entity resulting from
         such Business Combination (including, without limitation, an entity
         which as a result of such transaction owns the Company or all or
         substantially all of the Company's assets either directly or through
         one or more subsidiaries)

         in substantially the same proportions relative to each other as their
         ownership, immediately prior to such Business Combination, of the
         Company Common Stock and Voting Stock of the Company, as the case may
         be, (B) no Person (excluding any entity resulting from such Business
         Combination, the Harris Group or any employee benefit plan (or related
         trust) sponsored or maintained by the Company, a subsidiary of the
         Company or such entity resulting from such Business Combination)
         beneficially owns, directly or indirectly, 40% or more of,
         respectively, the then-outstanding shares of common stock of the entity
         resulting from such Business Combination, or the combined voting power
         of the then-outstanding voting securities of such corporation except to
         the extent that such ownership existed prior to the Business
         Combination and (C) at least a majority of the members of the board of
         directors of the corporation resulting from such Business Combination
         were members of the Incumbent Board at the time of the execution of the
         initial agreement, or of the action of the Board, providing for such
         Business Combination; or

                  (iv) Approval by the shareholders of the Company of a complete
         liquidation or dissolution of the Company.

                  (v) For purposes of this paragraph 5(f), the "Harris Group"
         shall mean Messrs. Irving B. Harris, Neison Harris, King Harris,
         William W. Harris and June H. Barrows, and their respective spouses,

                  6. POST-EMPLOYMENT PERIOD PAYMENTS.

                  (a) If the Employment Period ends on the date on which
(without any extension thereof) it is then scheduled to end pursuant to
paragraph 5 hereof, or if the Employment Period ends early pursuant to paragraph
5 hereof for any reason, Executive shall cease to have any rights to salary,
bonus (if any), options, expense reimbursements or other benefits other than:
(i) any salary which has accrued but is unpaid, any reimbursable expenses which
have been incurred but are unpaid, and any unexpired vacation days which have
accrued under the Company's vacation policy but are unused, as of the end of the
Employment Period, (ii) any option rights or plan benefits which by their terms
extend beyond termination of Executive's employment (but only to the extent
provided in any option theretofore granted to Executive or in the SERP or any
other benefit plan in which Executive has participated as an employee of the
Company), (iii) any benefits to which Executive is entitled under Part 6 of
Subtitle B of Title I of the Employee Retirement Income Security Act of 1974, as
amended ("COBRA"), and (iv) any other amount(s) payable pursuant to the

                  (c) If the Employment Period ends early pursuant to paragraph
5 hereof on account of Termination for Cause, the Company shall pay Executive an
amount equal to that amount Executive would have received as salary (based on
Executive's salary then in effect) had the Employment Period remained in effect
until the later of the effective date of the Company's termination of
Executive's employment or the date thirty days after the Company's notice to
Executive of such termination. The Company shall make no further payments to
Executive except as contemplated in (a) (i), (ii) and (iii) above.

                  (d) If the Employment Period ends early pursuant to paragraph
5 hereof on account of a Termination without Cause or a Termination by Executive
for Good Reason, and such termination does not constitute a Termination
Following a Change of Control, the Company shall pay to Executive a lump sum
payment equal to three times Executive's base salary at the time of such
termination (or, if higher, Executive's Reference Salary). In addition, the
Company shall reimburse Executive (net after taxes on the receipt of such
reimbursement) for any premiums paid by Executive for health insurance provided
to Executive (for Executive and his dependents) by the Company subsequent to the
end of the Employment Period pursuant to the requirements of COBRA as in effect
on the date of this Agreement. The Company shall make no further payments to
Executive except as contemplated in (a)(i), (ii) and (iii) above. It is
expressly understood that the Company's payment obligations under this
subparagraph (d) shall cease in the event Executive breaches any of his
agreements in paragraph 7 or 8 hereof.

                  (e) If the Employment Period ends early pursuant to paragraph
5 hereof on account of a Termination by Executive with Advance Notice, and such
termination does not constitute a Termination Following a Change of Control, the
Company shall make no further payments to Executive except as contemplated in
(a) (i), (ii) and (iii) above.

                  (f)(i)   If the Employment Period ends early pursuant to

                           Following a Change of Control, Executive shall be
                           entitled to receive the following:

                           (A)      For a period of three years following the
                                    date of termination, Executive's base salary
                                    at the time of such termination (or, if
                                    higher, Executive's Reference Salary)
                                    payable at the times such amounts would have
                                    been paid; PROVIDED, HOWEVER, that if
                                    Executive so chooses, in his sole
                                    discretion, such payment under this
                                    subparagraph (f)(i)(A) shall be made in a
                                    lump sum;

                           (B)      A lump sum payment equal to Executive's
                                    Target Bonus for the year in which such
                                    termination occurs (or, if higher,
                                    Executive's Target Bonus for the preceding
                                    year or the year in which the Change of
                                    Control occurs);

                           (C)      If Executive's employment is terminated
                                    after July 1 of the then-current year, an
                                    additional amount equal to the product of
                                    (x) Executive's Target Bonus for the year in
                                    which such termination occurs (or, if
                                    higher, Executive's Target Bonus for the
                                    preceding year or the year in which the
                                    Change of Control occurs) multiplied by (y)
                                    a fraction, the numerator of which shall be
                                    the number of months that have elapsed, on
                                    the day of termination, during the
                                    then-current year

                                    (rounded up to the nearest full month) and
                                    the denominator of which shall be 12; and

                           (D)      For a period of one year following the date
                                    of termination, Executive shall be entitled
                                    to be a full participant in, and shall be
                                    entitled to the benefits provided under, the
                                    Company's Standard Executive Benefits
                                    Package (but shall not be entitled to stock
                                    option, performance share, performance unit,
                                    stock purchase, stock appreciation or
                                    similar equity-based compensatory benefit
                                    awards) and the additional benefits set
                                    forth in Section 3(f) hereof at the time of
                                    such termination (or, if higher, for the
                                    preceding year or the year in which the
                                    Change of Control occurs). If, however,
                                    Executive is not eligible to participate in
                                    the benefits as set forth in the preceding
                                    sentence, the Company shall reimburse
                                    Executive, on a monthly basis (net after
                                    taxes on the receipt of such reimbursement),
                                    for any premiums or other fees paid by
                                    Executive to obtain benefits (for Executive
                                    and his dependents) equivalent to the
                                    Standard Executive Benefits Package and the
                                    additional benefits set forth in Section
                                    3(f). Notwithstanding the foregoing or any
                                    other provision of this Agreement, (A) for
                                    the purpose of determining the period of
                                    continuation coverage to which the Executive
                                    or any of his dependents is entitled
                                    pursuant to the requirements of COBRA, the
                                    Executive's "qualifying event," subject to
                                    the requirements of applicable plans, will
                                    be the termination of the one-year period
                                    set forth above in this subparagraph
                                    (f)(i)(D) and the Executive will be
                                    considered to have remained actively
                                    employed on a full time basis through that
                                    date and (B) the Company shall reimburse
                                    Executive (net after taxes on the receipt of
                                    such reimbursement) for any premiums paid by
                                    Executive for health insurance provided to
                                    Executive (for Executives and his
                                    dependents) by the Company pursuant to the
                                    requirements of COBRA as in effect on the
                                    date of this Agreement.

         (ii)     LIMITATION ON PAYMENTS AND BENEFITS. Notwithstanding any
                  provision of this Agreement to the contrary, if any amount or
                  benefit to be paid or provided under this Agreement or
                  otherwise pursuant to or by reason of any other agreement,
                  policy, plan, program or arrangement, including without
                  limitation any bonus, stock option, performance share,
                  performance unit, stock appreciation right or similar right,
                  or the lapse or termination of any restriction on or the
                  vesting or exercisability of any of the foregoing would be an
                  "Excess Parachute Payment," within the meaning of Section 280G
                  of the Code, or any successor provision thereto, but for the
                  application of this sentence, then the payments and benefits
                  to be paid or provided under this Agreement shall be reduced
                  to the minimum extent necessary (but in no event to less than
                  zero) so that no portion of any such payment or benefit, as so
                  reduced, constitutes an Excess Parachute Payment; provided,
                  however, that the foregoing reduction shall be made only if
                  and to the extent that such reduction would result in an
                  increase in the aggregate payment and benefits to be provided
                  to Executive, determined on an after-tax basis (taking into
                  account the excise tax imposed pursuant to Section 4999 of the
                  Code, or any successor provision thereto, any tax imposed by
                  any comparable provision of state law, and any applicable
                  federal, state and local


<PAGE>   11



                  income taxes). The determination of whether any reduction in
                  such payments or benefits to be provided under this Agreement
                  is required pursuant to the preceding sentence shall be made
                  at the expense of the Company, if requested by the Executive
                  or the Company, by the Company's independent accountants. The
                  fact that the Executive's right to payments or benefits may be
                  reduced by reason of the limitations contained in this
                  paragraph 6(f) shall not of itself limit or otherwise affect
                  any other rights of the Executive other than pursuant to this
                  Agreement. In the event that any payment or benefit intended
                  to be provided under this Agreement is required to be reduced
                  pursuant to this paragraph 6(f), the Executive shall be
                  entitled to designate the payments and/or benefits to be so
                  reduced in order to give effect to this paragraph 6(f). The
                  Company shall provide the Executive with all information
                  reasonably requested by the Executive to permit the Executive
                  to make such designation. In the event that the Executive
                  fails to make such designation within 10 business days of the
                  Date of Termination, the Company may effect such reduction in
                  any manner it deems appropriate.

                  (g) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided hereunder on a timely basis, the Company will pay
interest on the amount or value thereof at an annualized rate of interest equal
to the so-called composite "prime rate" as quoted from time to time during the
relevant period in the Midwest Edition of THE WALL STREET JOURNAL. Such interest
will be payable as it accrues on demand. Any change in such prime rate will be
effective on and as of the date of such change.

                  (h) Executive shall not be required to mitigate the amount of
any payment or benefit provided for in this Agreement by seeking other
employment or otherwise.

                  7. CONFIDENTIAL INFORMATION. Executive acknowledges that the
information, observations and data obtained by him while employed by the Company
pursuant to this Agreement, as well as those obtained by him while employed by
the Company or any of its subsidiaries or affiliates or any predecessor thereof
prior to the date of this Agreement, concerning the business or affairs of the
Company or any of its subsidiaries or affiliates or any predecessor thereof
(unless and except to the extent the foregoing become generally known to and
available for use by the public other than as a result of Executive's acts or
omissions to act, "CONFIDENTIAL INFORMATION") are the property of the Company or
such subsidiary or affiliate. Therefore, Executive agrees that during the
Employment Period and for three years thereafter he shall not disclose any
Confidential Information without the prior written consent of the Board unless
and except to the extent that such disclosure is (i) made in the ordinary course
of Executive's performance of his duties under this Agreement or (ii) required
by any subpoena or other legal process (in which event Executive will give the
Company prompt notice of such subpoena or other legal process in order to permit
the Company to seek appropriate protective orders), and that he shall not use
any Confidential Information for his own account without the prior written
consent of the Board. Executive shall deliver to the Company at the termination
of the Employment Period, or at any other time the Company may reasonably
request, all memoranda, notes, plans, records, reports, computer tapes and
software and other documents and data (and copies thereof) relating to the
Confidential Information, or to the work product or the business of the Company
or any of its subsidiaries or affiliates which he may then possess or have under
his control.



<PAGE>   12



                  8. NON-COMPETE, NON-SOLICITATION.

                  (a) Executive acknowledges that in the course of his
employment with the Company pursuant to this Agreement he will become familiar,
and during the course of his employment by the Company or any of its
subsidiaries or affiliates or any predecessor thereof prior to the date of this
Agreement he has become familiar, with trade secrets and customer lists of and
other confidential information concerning the Company and its subsidiaries and
affiliates and predecessors thereof and that his services have been and will be
of special, unique and extraordinary value to the Company.

                  (b) Executive agrees that during the Employment Period and for
a period of one year after termination of his employment with the Company, he
shall not in any manner, directly or indirectly, through any person, firm or
corporation, alone or as a member of a partnership or as an officer, director,
shareholder, investor or employee of or in any other corporation or enterprise
or otherwise, engage or be engaged in, or assist any other person, firm,
corporation or enterprise in engaging or being engaged in, any business then
actively being conducted by the Company or any of its subsidiaries or
affiliates.

                  (c) Executive further agrees that during the Employment Period
and for a period of two years after termination of his employment with the
Company, he shall not in any manner, directly or indirectly, induce or attempt
to induce any employee of the Company or of any of its subsidiaries or
affiliates to quit or abandon his employ.

                  (d) Nothing in this paragraph 8 shall prohibit Executive from
being: (i) a shareholder in a mutual fund or a diversified investment company or
(ii) a passive owner of not more than 5% of the outstanding equity securities of
any class of a corporation or other entity which is publicly traded, so long as
Executive has no active participation in the business of such corporation or
other entity.

                  (e) If, at the time of enforcement of this paragraph, a court
holds that the restrictions stated herein are unreasonable under circumstances
then existing, the parties hereto agree that the maximum period, scope or
geographical area reasonable under such circumstances shall be substituted for
the stated period, scope or area and that the court shall be allowed to revise
the restrictions contained herein to cover the maximum period, scope and area
permitted by law.

                  9. ENFORCEMENT. Because Executive's services are unique and
because Executive has access to Confidential Information and work product, the
parties hereto agree that the Company would be damaged irreparably in the event
any of the provisions of paragraph 8 hereof were not performed in accordance
with their specific terms or were otherwise breached and that money damages
would be an inadequate remedy for any such non-performance or breach. Therefore,
the Company or its successors or assigns shall be entitled, in addition to other
rights and remedies existing in their favor, to an injunction or injunctions to
prevent any breach or threatened breach of any of such provisions and to enforce
such provisions specifically (without posting a bond or other security).

                  10. EXECUTIVE REPRESENTATIONS. Executive represents and
warrants to the Company that (i) the execution, delivery and performance of this
Agreement by Executive does not and will not conflict with, breach, violate or
cause a default under any contract, agreement, instrument, order, judgment or
decree to which Executive is a party or by which he is bound,


<PAGE>   13



(ii) Executive is not a party to or bound by any employment agreement,
noncompete agreement or confidentiality agreement with any other person or
entity and (iii) upon the execution and delivery of this Agreement by the
Company, this Agreement shall be the valid and binding obligation of Executive,
enforceable in accordance with its terms.

                  11. SURVIVAL. Subject to any limits on applicability contained
therein, paragraphs 7 and 8 hereof shall survive and continue in full force in
accordance with their terms notwithstanding any termination of the Employment
Period.

                  12. NOTICES. Any notice provided for in this Agreement shall
be in writing and shall be either personally delivered, sent by reputable
overnight carrier or mailed by first class mail, return receipt requested, to
the recipient at the address below indicated:

or such other address or to the attention of such other person as the recipient
party shall have specified by prior written notice to the sending party. Any
notice under this Agreement will be deemed to have been given when so delivered,
sent or mailed.

                  13. SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

                  14. PAYMENT OF CERTAIN COSTS AND EXPENSES.

                  (a) PREVAILING PARTY'S LITIGATION EXPENSES. In the event of
litigation between the Company and Executive related to this Agreement, the
non-prevailing party shall reimburse the prevailing party for any costs and
expenses (including without limitation attorneys' fees) reasonably incurred by
the prevailing party in connection therewith.

                  (b) CHANGE OF CONTROL OF THE COMPANY. Without limiting the
generality of (a) above, in the event that there is a Change of Control of the
Company, if it should appear to Executive that the Company has failed to comply
with any of its obligations under this Agreement or if it wrongfully withholds
from Executive any amount payable to Executive pursuant to the SERP,


<PAGE>   14



or in the event that the Company or any other person takes or threatens to take
any action to declare this Agreement void or unenforceable, or institutes any
litigation or other action or proceeding designed to deny, or to recover from,
Executive the benefits provided or intended to be provided to Executive
hereunder, the Company irrevocably authorizes Executive from time to time to
retain counsel of Executive's choice, at the expense of the Company as hereafter
provided, to advise and represent Executive in connection with any such
interpretation, enforcement or defense, including without limitation the
initiation or defense of any litigation or other legal action, whether by or
against the Company or any Director, officer, stockholder or other person
affiliated with the Company, in any jurisdiction. Notwithstanding any existing
or prior attorney-client relationship between the Company and such counsel, the
Company irrevocably consents to Executive's entering into an attorney-client
relationship with such counsel, and in that connection the Company and Executive
agree that a confidential relationship will exist between Executive and such
counsel. Without respect to whether Executive prevails, in whole or in part, in
connection with any of the foregoing, the Company will pay and be solely
financially responsible for any and all attorneys' and related fees and expenses
incurred by Executive in connection with any of the foregoing.

                  (c) SOURCE OF PAYMENTS. Except as otherwise specified herein,
in the event a Change of Control occurs, any payments to Executive pursuant to
this Agreement and the performance of the Company's obligations hereunder shall
be secured by amounts deposited or to be deposited in a trust established by the
Company for the benefit of Executive (and, at the Company's option, for the
benefit of other executives of the Company who are entitled to payments similar
to those provided in this Agreement) (the "Trust"). The Company shall transfer
to such Trust assets from which all or a portion of the payments provided under
this Agreement are to be paid, provided that such assets of the Trust shall at
all times be subject to the claims of general unsecured creditors of the Company
and that neither Executive nor any other person entitled to payments through the
Trust shall at any time have a prior claim to such assets. Any payments to
Executive under this Agreement that are not paid through the Trust shall be paid
from the Company's general assets, and Executive shall have the status of a
general unsecured creditor with respect to the Company's obligations to make
payments under this Agreement.

                  15. COMPLETE AGREEMENT. This Agreement embodies the complete
agreement and understanding between the parties with respect to the subject
matter hereof and effective as of its date supersedes and preempts any prior
understandings, agreements or representations by or between the parties, written
or oral, which may have related to the subject matter hereof in any way.

                  16. COUNTERPARTS. This Agreement may be executed in separate
counterparts, each of which shall be deemed to be an original and both of which
taken together shall constitute one and the same agreement.

                  17. SUCCESSORS AND ASSIGNS. This Agreement shall bind and
inure to the benefit of and be enforceable by Executive, the Company and their
respective heirs, executors, personal representatives, successors and assigns,
except that neither party may assign any of his or its rights or delegate any of
his or its obligations hereunder without the prior written consent of the other
party. Executive hereby consents to the assignment by the Company of all of its
rights and obligations hereunder to any successor to the Company by merger or
consolidation or purchase of all or substantially all of the Company's assets,
provided such transferee or successor assumes the liabilities of the Company
hereunder.



<PAGE>   15


                  18. CHOICE OF LAW. This Agreement shall be governed by the
internal law, and not the laws of conflicts, of the State of Ohio.

                  19. AMENDMENT AND WAIVER. The provisions of this Agreement may
be amended or waived only with the prior written consent of the Company and
Executive, and no course of conduct or failure or delay in enforcing the
provisions of this Agreement shall affect the validity, binding effect or
enforceability of this Agreement.

                  IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the date written below.

                          RESTATED EMPLOYMENT AGREEMENT


                  This RESTATED EMPLOYMENT AGREEMENT ("Agreement") effective as
of January 1, 1999, between Penton Media, Inc. (formerly known as Penton
Publishing, Inc.), a Delaware corporation (the "COMPANY"), and Daniel J. Ramella
("EXECUTIVE")

                                   WITNESSETH:

                  WHEREAS, Executive is presently the President and Chief
Operating Officer of the Company and has made and is expected to continue to
make major contributions to the profitability, growth and financial strength of
the Company;

                  WHEREAS, the Company recognizes that, as is the case with many
publicly held companies, the possibility of a Change of Control (as that term is
hereafter defined) exists;

                  WHEREAS, the Company wishes to assure itself of both present
and future continuity of management in the event of any Change of Control;

                  WHEREAS, the Company wishes to ensure that certain of its
executives are not practically disabled from discharging their duties upon a
Change of Control; and

                  WHEREAS, the Company and Executive currently are parties to an
Employment Agreement (the "PRIOR AGREEMENT") providing certain benefits, and the
Company and Executive desire to amend and restate the Prior Agreement;

                  NOW, THEREFORE, in consideration of the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

                  1. EMPLOYMENT. The Company shall employ Executive, and
Executive accepts continued employment with the Company as of the date hereof,
upon the terms and conditions set forth in this Agreement for the period
beginning on the date hereof and ending as provided in paragraph 5 hereof (the
"EMPLOYMENT PERIOD").

                  2.       POSITION AND DUTIES.

                  (a) During the Employment Period, Executive shall serve as the
chief operating officer of the Company and shall have the normal duties,
responsibilities and authority of an executive serving in such position, subject
to the power of the Board of Directors of the Company (the "BOARD") or the Chief
Executive Officer of the Company to expand or limit such duties,
responsibilities and authority, either generally or in specific instances.
Executive shall have the title President of the Company, subject to the power of
the Board to change such title from time to time. During the Employment Period,
Executive shall also serve as a director of the Company for so long as the Board
(or a nominating committee of the Board) nominates him to that position and he
is elected to it, and as a director of any affiliate of the Company designated
by the Board for so long as the Board causes him to be elected to such position.

                  (b) Executive shall report to the Chief Executive Officer of
the Company.

                  (c) During the Employment Period, Executive shall devote his
best efforts and his full business time and attention (except for permitted
vacation periods, reasonable periods of illness or other incapacity, and,
provided such activities do not have more than a DE MINIMIS effect on
Executive's performance of his duties under this Agreement, participation in
charitable and civic endeavors and management of Executive's personal
investments and business interests) to the business and affairs of the Company,
its subsidiaries and affiliates. Executive shall perform his duties and
responsibilities to the best of his abilities in a diligent, trustworthy,
businesslike and efficient manner.

                  (d) Executive shall perform his duties and responsibilities
principally in the Cleveland, Ohio metropolitan area, and shall not be required
to travel outside that area any more extensively than he has done in the past in

                  3. COMPENSATION AND BENEFITS.

                  (a) SALARY. The Company agrees to pay Executive a salary
during the Employment Period, in semi-monthly installments. Executive's initial
salary shall be $365,000 per year. The Compensation Committee of the Board (or,

time to time and may, in its sole discretion, increase it.

                  (b) BONUS(ES). Effective January 1, 1999 and for subsequent
years, Executive will be eligible for an annual bonus based on the achievement
of specified Company goals (the "Target Bonus") (as determined by the
Compensation Committee of the Board (or, if there is no such Committee, the
Board)). Any bonus payable pursuant to this subparagraph (b) may, at the
discretion of the Compensation Committee of the Board (or, if there is no such
Committee, the Board), after considering any preference expressed by Executive,
be paid in the form of cash, in a Performance Shares Award related to shares of
the Company's Common Stock or in a combination of both.

                  (c) STOCK OPTIONS. The Company has adopted a plan (the "1998
STOCK OPTION PLAN") pursuant to which options to purchase shares of the
Company's Common Stock, and other equity-based incentive compensation awards,
may be granted to Executive and other officers of the Company. Executive shall
be eligible to receive grants of options and other awards under the 1998 Stock
Option Plan, at the discretion of the Compensation Committee of the Board (or,
if there is no such Committee, the Board). Under the terms of the 1998 Stock
Option Plan, the Compensation Committee of the Board (or, if there is no such
Committee, the Board) has the right to amend the 1998 Stock Option Plan. If, at
the time of the grant of any option pursuant to this paragraph (c), the issuance
of shares upon exercise thereof has not been registered under the Securities Act
of 1933, as amended, it shall be a condition to such grant that Executive
execute and deliver to the Company a certificate confirming that Executive is an
accredited investor (as such term is used in Regulation D under such Act) and
including transfer restrictions and other provisions customary in connection
with grants under such circumstances. Each option to be granted as set forth
above shall be substantially in the form of EXHIBIT 1 attached to this
Agreement, except that it is understood that reference to any then existing
registration statement or related plan information document in EXHIBIT 1, or its
equivalent, shall be included if and only if the same exists at the time of
grant and is relevant to such option.

Executive for all reasonable expenses incurred by him during the Employment
Period in the course of performing his duties under this Agreement that are
consistent with the Company's policies in effect from time to time with respect
to travel, entertainment and other business expenses, subject to the Company's
requirements applicable generally with respect to reporting and documentation of
such expenses. Executive acknowledges that under the Company's current air

                           as such additional coverage is available at standard
                           rates from the insurer providing term life insurance
                           coverage under the Standard Executive Benefits
                           Package or from a comparable insurer acceptable to
                           the Company;

                  (ii)     supplementary long-term disability coverage in an
                           amount that will include maximum covered annual

                           supplementary coverage is available at standard rates
                           from the insurer providing long-term disability
                           coverage under the Standard Executive Benefits
                           Package or a comparable insurer acceptable to the

                  (iii)    pursuant to authorization by the Compensation
                           Committee of the Board (or, if there is no such
                           Committee, the Board), participation in the Penton
                           Media, Inc. Supplemental Executive Retirement Plan

                           in effect, except that the beginning date for accrual
                           of a benefit shall be the date on which Executive's
                           employment with the Company began.

                  (g) INDEMNIFICATION. With respect to Executive's acts or
failures to act during the Employment Period in his capacity as a director,
officer, employee or agent of the Company, Executive shall be entitled to

                  4. ADJUSTMENTS. Notwithstanding any other provision of this
Agreement, it is expressly understood and agreed that if there is a significant
reduction in the level of the business to which Executive's duties under this
Agreement relate, or if all or any significant part of such business is disposed
of by the Company and/or its subsidiaries or affiliates during the Employment
Period but Executive thereafter remains an employee of the Company, the
Compensation Committee of the Board (or, if there is no such Committee, the
Board) may make adjustments in Executive's duties, responsibility and authority,
and in Executive's compensation, as the Compensation Committee of the Board (or,
if there is no such Committee, the Board) deems appropriate to reflect such
reduction or disposition.

                  5.       EMPLOYMENT PERIOD.

                  (a) Except as hereinafter provided, the Employment Period

Period begins which precedes Executive's sixty-fifth birthday by more than two
years, unless the Employment Period shall have ended early pursuant to (c) below
or either party shall have given the other party written notice that the
extension provision in this sentence shall no longer apply, the Employment
Period shall be extended for an additional year (unless Executive's sixty-fifth
birthday occurs during such additional year, in which event the Employment
Period shall be extended only until such birthday). In no event shall the
Employment Period be extended beyond Executive's sixty-fifth birthday except by
mutual written agreement of the Company and Executive.

                  (c) Notwithstanding (a) and (b) above, the Employment Period

                           on account of Executive's having become unable (as
                           determined by the Board in good faith) to regularly
                           perform his duties hereunder by reason of illness or
                           incapacity for a period of more than six (6)

                  (iv)     the Company's termination of Executive's employment
                           for Cause ("TERMINATION FOR CAUSE");

                  (v)      the Company's termination of Executive's employment
                           other than a Termination for Disability or a

                           effective date of such termination identifying such
                           termination as a Termination by Executive for Good
                           Reason and identifying the Good Reason ("TERMINATION
                           BY EXECUTIVE FOR GOOD REASON") (it being expressly

                           understood that Executive's giving notice that the
                           extension provision in the first sentence of

                           hundred twenty (120) days prior to the effective date
                           of such termination identifying such termination as a
                           Termination by Executive with Advance Notice
                           ("TERMINATION BY EXECUTIVE WITH ADVANCE NOTICE") (it
                           being expressly understood that Executive's giving

                           account of a Termination without Cause before the
                           second anniversary of a Change of Control, (B) on
                           account of a Termination by Executive for Good Reason
                           before the second anniversary of a Change of Control
                           or (C) in connection with but prior to a Change of
                           Control and following the commencement of any
                           discussion with any third party that (i) requests or
                           suggests that Executive's employment be terminated

                           (collectively, "TERMINATION FOLLOWING A CHANGE OF
                           CONTROL").

                  (d)      For purposes of this Agreement, "CAUSE" shall mean:

                  (i)      the commission by Executive of a felony or a crime
                           involving moral turpitude;

                  (ii)     the commission by Executive of a fraud;

                           or any of its subsidiaries or affiliates that harms
                           or damages any of them to any extent;

                  (iv)     conduct by Executive that brings the Company or any
                           of its subsidiaries or affiliates into substantial
                           public disgrace or disrepute;

                  (v)      gross negligence or willful misconduct by Executive
                           with respect to the Company or any of its
                           subsidiaries or affiliates;

                  (vi)     repudiation of this Agreement by Executive or
                           Executive's abandonment of his employment with the

                           Termination by Executive for Good Reason or a
                           Termination by Executive with Advance Notice shall
                           not constitute such a repudiation or abandonment);

                  (vii)    breach by Executive of any of the agreements in
                           paragraph 8 hereof prior to the end of the Employment
                           Period; or



<PAGE>   6



                  (viii)   any other breach by Executive of this Agreement which
                           is material and which is not cured within thirty (30)
                           days after written notice thereof to Executive from
                           the Company.

                  (ix)     Notwithstanding the foregoing, Executive shall in no
                           event be deemed to have been terminated for "Cause"
                           hereunder unless prior to his termination there shall
                           have been delivered to Executive a copy of a
                           resolution duly adopted by the affirmative vote of
                           not less than a majority of the non- employee
                           Directors then in office at a meeting of the Board
                           called and held for such purpose, after reasonable
                           notice to Executive and an opportunity for Executive,
                           together with Executive's counsel (if Executive
                           chooses to have counsel present at such meeting), to
                           be heard before the Board, finding that, in the good
                           faith opinion of the Board, Executive had committed
                           an act constituting "Cause" as herein defined and
                           specifying the particulars thereof in detail. While
                           such a determination will be a condition precedent
                           for the existence of "Cause" for purposes of this
                           Agreement, such a determination will not be
                           determinative or create a presumption that "Cause" in
                           fact exists and nothing herein will limit the right
                           of Executive or his beneficiaries to contest the
                           validity or propriety of any such determination.

                  (e)      For purposes of this Agreement, "GOOD REASON" shall
                           mean:

                  (i)      a reduction by the Company in Executive's salary to
                           an amount less than "EXECUTIVE'S REFERENCE SALARY"
                           (i.e., Executive's initial salary or, in the event
                           the Employment Period has been extended pursuant to
                           paragraph 5(b) hereof, Executive's salary on the date
                           on which the most recent such extension occurred) or
                           any downward adjustment in Executive's Target Bonus;
                           or

                  (ii)     the Company's giving notice that the extension
                           provision in the first sentence of paragraph 5(b)
                           hereof shall no longer apply; or

                  (iii)    any breach by the Company of this Agreement which is
                           material and which is not cured within thirty (30)
                           days after written notice thereof to the Company from
                           Executive.

                  (f) For purposes of this Agreement, "CHANGE OF CONTROL" shall
mean the occurrence of any of the following events during the Employment Period:

                  (i) The acquisition by any individual, entity or group (within
         the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
         Act of 1934, as amended (the "Exchange Act")) (a "Person") of
         beneficial ownership (within the meaning of Rule 13d-3 promulgated
         under the Exchange Act) of 40% or more of either: (A) the
         then-outstanding shares of common stock of the Company (the "Company
         Common Stock") or (B) the combined voting power of the then-outstanding
         voting securities of the Company entitled to vote generally in the
         election of directors ("Voting Stock"); PROVIDED, HOWEVER, that for
         purposes of this subparagraph (i), the following acquisitions shall not
         constitute a Change of Control: (A) any acquisition directly from the
         Company, (B) any acquisition by the Company, a subsidiary of the
         Company or the Harris Group, (C) any acquisition by any employee
         benefit plan (or related trust) sponsored or maintained by the Company
         or any subsidiary of the Company,


<PAGE>   7



         or (D) any acquisition by any Person pursuant to a transaction which
         complies with clauses (A), (B) and (C) of subparagraph (iii) of this
         paragraph 5(f); or

                  (ii) Individuals who, as of the date hereof, constitute the
         Board (the "Incumbent Board") cease for any reason (other than death or
         disability) to constitute at least a majority of the Board; PROVIDED,
         HOWEVER, that any individual becoming a director subsequent to the date
         hereof whose election, or nomination for election by the Company's
         shareholders, was approved by a vote of at least a majority of the
         directors then comprising the Incumbent Board (either by a specific
         vote or by approval of the proxy statement of the Company in which such
         person is named as a nominee for director, without objection to such
         nomination) shall be considered as though such individual were a member
         of the Incumbent Board, but excluding for this purpose, any such
         individual whose initial assumption of office occurs as a result of an
         actual or threatened election contest (within the meaning of Rule
         14a-11 of the Exchange Act) with respect to the election or removal of
         directors or other actual or threatened solicitation of proxies or
         consents by or on behalf of a Person other than the Board; or

         consolidation or sale or other disposition of all or substantially all
         of the assets of the Company (a "Business Combination"), in each case,
         unless, following such Business Combination, (A) all or substantially
         all of the individuals and entities who were the beneficial owners,
         respectively, of the Company Common Stock and Voting Stock immediately
         prior to such Business Combination beneficially own, directly or
         indirectly, more than a majority of, respectively, the then-outstanding
         shares of common stock and the combined voting power of the
         then-outstanding voting securities entitled to vote generally in the
         election of directors, as the case may be, of the entity resulting from
         such Business Combination (including, without limitation, an entity
         which as a result of such transaction owns the Company or all or
         substantially all of the Company's assets either directly or through
         one or more subsidiaries) in substantially the same proportions
         relative to each other as their ownership, immediately prior to such
         Business Combination, of the Company Common Stock and Voting Stock of
         the Company, as the case may be, (B) no Person (excluding any entity
         resulting from such Business Combination, the Harris Group or any

         Business Combination) beneficially owns, directly or indirectly, 40% or
         more of, respectively, the then-outstanding shares of common stock of
         the entity resulting from such Business Combination, or the combined
         voting power of the then-outstanding voting securities of such
         corporation except to the extent that such ownership existed prior to
         the Business Combination and (C) at least a majority of the members of
         the board of directors of the corporation resulting from such Business
         Combination were members of the Incumbent Board at the time of the
         execution of the initial agreement, or of the action of the Board,
         providing for such Business Combination; or

                  (iv) Approval by the shareholders of the Company of a complete

         for the benefit of such persons (acting in their capacity as trustees
         of such trusts),

         and executors of estates of such persons (acting in their capacity as
         executors of such estates), and each person of which any of the
         foregoing owns (i) more than fifty percent (50%) of the voting stock or
         other voting interests and (ii) stock or other interests representing
         more than fifty percent (50%) of the total value of the stock or other
         interests of such person.

                  6. POST-EMPLOYMENT PERIOD PAYMENTS.

                  (a) If the Employment Period ends on the date on which
(without any extension thereof) it is then scheduled to end pursuant to
paragraph 5 hereof, or if the Employment Period ends early pursuant to paragraph
5 hereof for any reason, Executive shall cease to have any rights to salary,
bonus (if any), options, expense reimbursements or other benefits other than:
(i) any salary which has accrued but is unpaid, any reimbursable expenses which
have been incurred but are unpaid, and any unexpired vacation days which have
accrued under the Company's vacation policy but are unused, as of the end of the
Employment Period, (ii) any option rights or plan benefits which by their terms
extend beyond termination of Executive's employment (but only to the extent
provided in any option theretofore granted to Executive or in the SERP or any
other benefit plan in which Executive has participated as an employee of the
Company), (iii) any benefits to which Executive is entitled under Part 6 of
Subtitle B of Title I of the Employee Retirement Income Security Act of 1974, as
amended ("COBRA"), and (iv) any other amount(s) payable pursuant to the
succeeding provisions of this paragraph 6.

                  (b) If the Employment Period ends pursuant to paragraph 5
hereof on Executive's sixty-fifth birthday, or if the Employment Period ends
early pursuant to paragraph 5 hereof on account of Executive's death, Retirement
(provided such Retirement is not a Termination Following a Change of Control) or
Termination for Disability, the Company shall make no further payments to
Executive except as contemplated in (a)(i), (ii) and (iii) above.

                  (c) If the Employment Period ends early pursuant to paragraph
5 hereof on account of Termination for Cause, the Company shall pay Executive an
amount equal to that amount Executive would have received as salary (based on
Executive's salary then in effect) had the Employment Period remained in effect
until the later of the effective date of the Company's termination of
Executive's employment or the date thirty days after the Company's notice to
Executive of such termination. The Company shall make no further payments to
Executive except as contemplated in (a)(i), (ii) and (iii) above.

                  (d) If the Employment Period ends early pursuant to paragraph
5 hereof on account of a Termination without Cause or a Termination by Executive
for Good Reason, and such termination does not constitute a Termination
Following a Change of Control, the Company shall pay to Executive a lump sum
payment equal to three times Executive's base salary at the time of such
termination (or, if higher, Executive's Reference Salary). In addition, the
Company shall reimburse Executive (net after taxes on the receipt of such
reimbursement) for any premiums paid by Executive for health insurance provided
to Executive (for Executive and his dependents) by the Company subsequent to the
end of the Employment Period pursuant to the requirements of COBRA as in effect
on the date of this Agreement. The Company shall make no further payments to
Executive except as contemplated in (a)(i), (ii) and (iii) above. It is
expressly understood that the Company's payment obligations under this
subparagraph (d) shall cease in the event Executive breaches any of his
agreements in paragraph 7 or 8 hereof.



<PAGE>   9



                  (e) If the Employment Period ends early pursuant to paragraph
5 hereof on account of a Termination by Executive with Advance Notice, and such
termination does not constitute a Termination Following a Change of Control, the
Company shall make no further payments to Executive except as contemplated in
(a)(i), (ii) and (iii) above.

                  (f)(i)   If the Employment Period ends early pursuant to
                           paragraph 5 hereof on account of a Termination
                           Following a Change of Control, Executive shall be
                           entitled to receive the following:

                           (A)      For a period of three years following the
                                    date of termination, Executive's base salary
                                    at the time of such termination (or, if
                                    higher, Executive's Reference Salary)
                                    payable at the times such amounts would have
                                    been paid; PROVIDED, HOWEVER, that if
                                    Executive so chooses, in his sole
                                    discretion, such payment under this
                                    subparagraph (f)(i)(A) shall be made in a
                                    lump sum;

                           (B)      A lump sum payment equal to Executive's
                                    Target Bonus for the year in which such
                                    termination occurs (or, if higher,
                                    Executive's Target Bonus for the preceding
                                    year or the year in which the Change of
                                    Control occurs);

                           (C)      If Executive's employment is terminated
                                    after July 1 of the then- current year, an
                                    additional amount equal to the product of
                                    (x) Executive's Target Bonus for the year in
                                    which such termination occurs (or, if
                                    higher, Executive's Target Bonus for the
                                    preceding year or the year in which the
                                    Change of Control occurs) multiplied by (y)
                                    a fraction, the numerator of which shall be
                                    the number of months that have elapsed, on
                                    the day of termination, during the
                                    then-current year (rounded up to the nearest
                                    full month) and the denominator of which
                                    shall be 12; and

                           (D)      For a period of one year following the date
                                    of termination, Executive shall be entitled
                                    to be a full participant in, and shall be
                                    entitled to the benefits provided under, the
                                    Company's Standard Executive Benefits
                                    Package (but shall not be entitled to stock
                                    option, performance share, performance unit,
                                    stock purchase, stock appreciation or
                                    similar equity-based compensatory benefit
                                    awards) and the additional benefits set
                                    forth in Section 3(f) hereof at the time of
                                    such termination (or, if higher, for the
                                    preceding year or the year in which the
                                    Change of Control occurs). If, however,
                                    Executive is not eligible to participate in
                                    the benefits as set forth in the preceding
                                    sentence, the Company shall reimburse
                                    Executive, on a monthly basis (net after
                                    taxes on the receipt of such reimbursement),
                                    for any premiums or other fees paid by
                                    Executive to obtain benefits (for Executive
                                    and his dependents) equivalent to the
                                    Standard Executive Benefits Package and the
                                    additional benefits set forth in Section
                                    3(f). Notwithstanding the foregoing or any
                                    other provision of this Agreement, (A) for
                                    the purpose of determining the period of
                                    continuation coverage to which the Executive
                                    or any of his dependents is entitled
                                    pursuant to the


<PAGE>   10



                                    requirements of COBRA, the Executive's
                                    "qualifying event," subject to the
                                    requirements of applicable plans, will be
                                    the termination of the one-year period set
                                    forth above in this subparagraph (f)(i)(D)
                                    and the Executive will be considered to have
                                    remained actively employed on a full time
                                    basis through that date and (B) the Company
                                    shall reimburse Executive (net after taxes
                                    on the receipt of such reimbursement) for
                                    any premiums paid by Executive for health
                                    insurance provided to Executive (for
                                    Executives and his dependents) by the
                                    Company pursuant to the requirements of
                                    COBRA as in effect on the date of this
                                    Agreement.

                  (ii)     LIMITATION ON PAYMENTS AND BENEFITS. Notwithstanding
                           any provision of this Agreement to the contrary, if
                           any amount or benefit to be paid or provided under
                           this Agreement or otherwise pursuant to or by reason
                           of any other agreement, policy, plan, program or
                           arrangement, including without limitation any bonus,
                           stock option, performance share, performance unit,
                           stock appreciation right or similar right, or the
                           lapse or termination of any restriction on or the
                           vesting or exercisability of any of the foregoing
                           would be an "Excess Parachute Payment," within the
                           meaning of Section 280G of the Code, or any successor
                           provision thereto, but for the application of this
                           sentence, then the payments and benefits to be paid
                           or provided under this Agreement shall be reduced to
                           the minimum extent necessary (but in no event to less
                           than zero) so that no portion of any such payment or
                           benefit, as so reduced, constitutes an Excess
                           Parachute Payment; provided, however, that the
                           foregoing reduction shall be made only if and to the
                           extent that such reduction would result in an
                           increase in the aggregate payment and benefits to be
                           provided to Executive, determined on an after-tax
                           basis (taking into account the excise tax imposed
                           pursuant to Section 4999 of the Code, or any
                           successor provision thereto, any tax imposed by any
                           comparable provision of state law, and any applicable
                           federal, state and local income taxes). The
                           determination of whether any reduction in such
                           payments or benefits to be provided under this
                           Agreement is required pursuant to the preceding
                           sentence shall be made at the expense of the Company,
                           if requested by the Executive or the Company, by the
                           Company's independent accountants. The fact that the
                           Executive's right to payments or benefits may be
                           reduced by reason of the limitations contained in
                           this paragraph 6(f) shall not of itself limit or
                           otherwise affect any other rights of the Executive
                           other than pursuant to this Agreement. In the event
                           that any payment or benefit intended to be provided
                           under this Agreement is required to be reduced
                           pursuant to this paragraph 6(f), the Executive shall
                           be entitled to designate the payments and/or benefits
                           to be so reduced in order to give effect to this
                           paragraph 6(f). The Company shall provide the
                           Executive with all information reasonably requested
                           by the Executive to permit the Executive to make such
                           designation. In the event that the Executive fails to
                           make such designation within 10 business days of the
                           Date of Termination, the Company may effect such
                           reduction in any manner it deems appropriate.

                  (g) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided


<PAGE>   11



hereunder on a timely basis, the Company will pay interest on the amount or
value thereof at an annualized rate of interest equal to the so-called composite
"prime rate" as quoted from time to time during the relevant period in the
Midwest Edition of THE WALL STREET JOURNAL. Such interest will be payable as it
accrues on demand. Any change in such prime rate will be effective on and as of
the date of such change.

                  (h) Executive shall not be required to mitigate the amount of
any payment or benefit provided for in this Agreement by seeking other
employment or otherwise.

                  7. CONFIDENTIAL INFORMATION. Executive acknowledges that the
information, observations and data obtained by him while employed by the Company
pursuant to this Agreement, as well as those obtained by him while employed by
the Company or any of its subsidiaries or affiliates or any predecessor thereof
prior to the date of this Agreement, concerning the business or affairs of the
Company or any of its subsidiaries or affiliates or any predecessor thereof
(unless and except to the extent the foregoing become generally known to and
available for use by the public other than as a result of Executive's acts or
omissions to act, "CONFIDENTIAL INFORMATION") are the property of the Company or
such subsidiary or affiliate. Therefore, Executive agrees that during the
Employment Period and for three years thereafter he shall not disclose any
Confidential Information without the prior written consent of the Chief
Executive Officer of the Company unless and except to the extent that such
disclosure is (i) made in the ordinary course of Executive's performance of his
duties under this Agreement or (ii) required by any subpoena or other legal
process (in which event Executive will give the Company prompt notice of such
subpoena or other legal process in order to permit the Company to seek
appropriate protective orders), and that he shall not use any Confidential
Information for his own account without the prior written consent of the Chief
Executive Officer of the Company. Executive shall deliver to the Company at the
termination of the Employment Period, or at any other time the Company may
reasonably request, all memoranda, notes, plans, records, reports, computer
tapes and software and other documents and data (and copies thereof) relating to
the Confidential Information, or to the work product or the business of the
Company or any of its subsidiaries or affiliates which he may then possess or
have under his control.

                  8. NON-COMPETE, NON-SOLICITATION.

                  (a) Executive acknowledges that in the course of his
employment with the Company pursuant to this Agreement he will become familiar,
and during the course of his employment by the Company or any of its
subsidiaries or affiliates or any predecessor thereof prior to the date of this
Agreement he has become familiar, with trade secrets and customer lists of and
other confidential information concerning the Company and its subsidiaries and
affiliates and predecessors thereof and that his services have been and will be
of special, unique and extraordinary value to the Company.

                  (b) Executive agrees that during the Employment Period and for
a period of one year after termination of his employment with the Company, he
shall not in any manner, directly or indirectly, through any person, firm or
corporation, alone or as a member of a partnership or as an officer, director,
shareholder, investor or employee of or in any other corporation or enterprise
or otherwise, engage in or be engaged in, or assist any other person, firm,
corporation or enterprise in engaging or being engaged in, any business then
actively being conducted by the Company or any of its subsidiaries or
affiliates.



<PAGE>   12



                  (c) Executive further agrees that during the Employment Period
and for a period of two years after termination of his employment with the
Company, he shall not in any manner, directly or indirectly, induce or attempt
to induce any employee of the Company or of any of its subsidiaries or
affiliates to quit or abandon his employ.

                  (d) Nothing in this paragraph 8 shall prohibit Executive from
being: (i) a shareholder in a mutual fund or a diversified investment company or
(ii) a passive owner of not more than 5% of the outstanding equity securities of
any class of a corporation or other entity which is publicly traded, so long as
Executive has no active participation in the business of such corporation or
other entity.

                  (e) If, at the time of enforcement of this paragraph, a court
holds that the restrictions stated herein are unreasonable under circumstances
then existing, the parties hereto agree that the maximum period, scope or
geographical area reasonable under such circumstances shall be substituted for
the stated period, scope or area and that the court shall be allowed to revise
the restrictions contained herein to cover the maximum period, scope and area
permitted by law.

                  9. ENFORCEMENT. Because Executive's services are unique and
because Executive has access to Confidential Information and work product, the
parties hereto agree that the Company would be damaged irreparably in the event
any of the provisions of paragraph 8 hereof were not performed in accordance
with their specific terms or were otherwise breached and that money damages
would be an inadequate remedy for any such non-performance or breach. Therefore,
the Company or its successors or assigns shall be entitled, in addition to other
rights and remedies existing in their favor, to an injunction or injunctions to
prevent any breach or threatened breach of any of such provisions and to enforce
such provisions specifically (without posting a bond or other security).

or such other address or to the attention of such other person as the recipient
party shall have specified by prior written notice to the sending party. Any

sent or mailed.

                  13. SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

                  14. PAYMENT OF CERTAIN COSTS AND EXPENSES.

                  (a) PREVAILING PARTY'S LITIGATION EXPENSES. In the event of
litigation between the Company and Executive related to this Agreement, the
non-prevailing party shall reimburse the prevailing party for any costs and
expenses (including without limitation attorneys' fees) reasonably incurred by
the prevailing party in connection therewith.

                  (b) CHANGE OF CONTROL OF THE COMPANY. Without limiting the
generality of (a) above, in the event that there is a Change of Control of the
Company, if it should appear to Executive that the Company has failed to comply
with any of its obligations under this Agreement or if it wrongfully withholds
from Executive any amount payable to Executive pursuant to the SERP, or in the
event that the Company or any other person takes or threatens to take any action
to declare this Agreement void or unenforceable, or institutes any litigation or
other action or proceeding designed to deny, or to recover from, Executive the
benefits provided or intended to be provided to Executive hereunder, the Company
irrevocably authorizes Executive from time to time to retain counsel of
Executive's choice, at the expense of the Company as hereafter provided, to
advise and represent Executive in connection with any such interpretation,
enforcement or defense, including without limitation the initiation or defense
of any litigation or other legal action, whether by or against the Company or
any Director, officer, shareholder or other person affiliated with the Company,
in any jurisdiction. Notwithstanding any existing or prior attorney-client
relationship between the Company and such counsel, the Company irrevocably
consents to Executive's entering into an attorney-client relationship with such
counsel, and in that connection the Company and Executive agree that a
confidential relationship will exist between Executive and such counsel. Without
respect to whether Executive prevails, in whole or in part, in connection with
any of the foregoing, the Company will pay and be solely financially responsible
for any and all attorneys' and related fees and expenses incurred by Executive
in connection with any of the foregoing.

                  (c) SOURCE OF PAYMENTS. Except as otherwise specified herein,
in the event a Change of Control occurs, any payments to Executive pursuant to
this Agreement and the


<PAGE>   14



performance of the Company's obligations hereunder shall be secured by amounts
deposited or to be deposited in a trust established by the Company for the
benefit of Executive (and, at the Company's option, for the benefit of other
executives of the Company who are entitled to payments similar to those provided
in this Agreement) (the "Trust"). The Company shall transfer to such Trust
assets from which all or a portion of the payments provided under this Agreement
are to be paid, provided that such assets of the Trust shall at all times be
subject to the claims of general unsecured creditors of the Company and that
neither Executive nor any other person entitled to payments through the Trust
shall at any time have a prior claim to such assets. Any payments to Executive
under this Agreement that are not paid through the Trust shall be paid from the
Company's general assets, and Executive shall have the status of a general
unsecured creditor with respect to the Company's obligations to make payments
under this Agreement.

                  15. COMPLETE AGREEMENT. This Agreement embodies the complete
agreement and understanding between the parties with respect to the subject
matter hereof and effective as of its date supersedes and preempts any prior
understandings, agreements or representations by or between the parties, written
or oral, which may have related to the subject matter hereof in any way.

                  16. COUNTERPARTS. This Agreement may be executed in separate
counterparts, each of which shall be deemed to be an original and both of which
taken together shall constitute one and the same agreement.

                  17. SUCCESSORS AND ASSIGNS. This Agreement shall bind and
inure to the benefit of and be enforceable by Executive, the Company and their
respective heirs, executors, personal representatives, successors and assigns,
except that neither party may assign any of his or its rights or delegate any of
his or its obligations hereunder without the prior written consent of the other
party. Executive hereby consents to the assignment by the Company of all of its
rights and obligations hereunder to any successor to the Company by merger or
consolidation or purchase of all or substantially all of the Company's assets,
provided such transferee or successor assumes the liabilities of the Company
hereunder.

                  18. CHOICE OF LAW. This Agreement shall be governed by the
internal law, and not the laws of conflicts, of the State of Ohio.

                  19. AMENDMENT AND WAIVER. The provisions of this Agreement may
be amended or waived only with the prior written consent of the Company and
Executive, and no course of conduct or failure or delay in enforcing the
provisions of this Agreement shall affect the validity, binding effect or
enforceability of this Agreement.

                              EMPLOYMENT AGREEMENT

     This EMPLOYMENT AGREEMENT ("AGREEMENT") made as of January 1, 1999, between
Penton Media, Inc. (formerly known as Penton Publishing, Inc.), a Delaware
corporation (the "COMPANY"), and James D. Atherton ("EXECUTIVE")

     In consideration of the mutual covenants contained herein and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

     1. EMPLOYMENT. The Company shall employ Executive, and Executive accepts
continued employment with the Company as of the date hereof, upon the terms and
conditions set forth in this Agreement for the period beginning on the date
hereof and ending as provided in paragraph 5 hereof (the "EMPLOYMENT PERIOD").

     2. POSITION AND DUTIES.

     (a) During the Employment Period, Executive shall serve as a Group
President of the Company, with initial responsibility for the Company's
Mechanical Systems/Construction, Government/Compliance, Management, Supply
Chain/Aviation, Industrial Shows of America, and Ancillary Product Sales and
Marketing Groups (the "Division"), and shall have the normal duties,
responsibilities and authority of an executive serving in such position, subject
to the power of the Board of Directors of the Company (the "BOARD") or the Chief
Executive Officer of the Company to expand or limit such duties,
responsibilities and authority, either generally or in specific instances.

     (b) Executive shall report to the Chief Executive Officer or the President
and Chief Operating Officer of the Company.

     (c) During the Employment Period, Executive shall devote his best efforts
and his full business time and attention (except for permitted vacation periods,
reasonable periods of illness or other incapacity, and, provided such activities
do not have more than a DE MINIMIS effect on Executive's performance of his
duties under this Agreement, participation in charitable and civic endeavors and
management of Executive's personal investments and business interests) to the
business and affairs of the Company and the Division. Executive shall perform
his duties and responsibilities to the best of his abilities in a diligent,
trustworthy, businesslike and efficient manner.

     (d) Executive shall perform his duties and responsibilities principally in
the Cleveland, Ohio metropolitan area, and shall not be required to travel
outside that area any more extensively than he has done in the past in the
ordinary course of the business of the Company.

     3. COMPENSATION AND BENEFITS.

     (a) SALARY. The Company agrees to pay Executive a salary during the
Employment Period, in semi-monthly installments. Executive's initial salary
shall be $265,000 per year. The Compensation Committee of the Board (or, if
there is no such Committee, the Board) shall review Executive's salary from time
to time and may, in its sole discretion, increase it.

     (b) BONUS(ES). Effective January 1, 1999 and for subsequent years,
Executive will be eligible for an annual bonus based on the achievement of
specified Company goals (the "Target Bonus") (as determined by the Compensation
Committee of the Board (or, if there is no such Committee, the Board)). Any
bonus payable pursuant to this subparagraph (b) may, at the discretion of the
Compensation Committee of the Board (or, if there is no such Committee, the
Board), after considering any preference expressed by Executive, be paid in the
form of cash, in a Performance Shares Award related to shares of the Company's
Common Stock or in a combination of both.

     (c) STOCK OPTIONS. The Company has adopted a plan (the "1998 STOCK OPTION
PLAN") pursuant to which options to purchase shares of the Company's Common
Stock, and other equity-based incentive compensation awards, may be granted to
Executive and other officers of the Company. Executive shall be eligible to
receive grants of options and other awards under the 1998 Stock Option Plan, at
the discretion of the Compensation Committee of the Board (or, if there is no
such Committee, the Board). Under the terms of the 1998 Stock Option Plan, the
Compensation Committee of the Board (or, if there is no such Committee, the
Board) has the right to amend the 1998 Stock Option Plan. If, at the time of the
grant of any option pursuant to this paragraph (c), the issuance of shares upon
exercise thereof has not been registered under the Securities Act of 1933, as
amended, it shall be a condition to such grant that Executive execute and
deliver to the Company a certificate confirming that Executive is an accredited
investor (as such term is used in Regulation D under such Act) and including
transfer restrictions and other provisions customary in connection with grants
under such circumstances. Each option to be granted as set forth above shall be
substantially in the form of EXHIBIT 1 attached to this Agreement, except that
it is understood that reference to any then existing registration statement or
related plan information document in EXHIBIT 1, or its equivalent, shall be
included if and only if the same exists at the time of grant and is relevant to
such option.

     (d) EXPENSE REIMBURSEMENT. The Company shall reimburse Executive for all
reasonable expenses incurred by him during the Employment Period in the course
of performing his duties under this Agreement that are consistent with the
Company's policies in effect from time to time with respect to travel,
entertainment and other business expenses, subject to the Company's requirements
applicable generally with respect to reporting and documentation of such
expenses. Executive acknowledges that under the Company's current air travel
reimbursement policy, reimbursement is limited to coach fare (plus Executive's
cost of any upgrade certificates used to upgrade to first class) on travel
within the United States and is limited to business class fare on travel to and
from foreign cities.

     (e) STANDARD EXECUTIVE BENEFITS PACKAGE. In addition to the salary,
bonus(es), stock options and expense reimbursements payable to Executive
pursuant to this paragraph, Executive shall be entitled during the Employment
Period to participate, on the same basis as other executives of the Company, in
the Company's Standard Executive Benefits Package. The Company's "STANDARD
EXECUTIVE BENEFITS PACKAGE" means those benefits (including insurance, vacation,
Company car or car allowance, equity-based benefits, and other benefits) for
which


<PAGE>   3



substantially all of the executives of the Company are from time to time
generally eligible, as determined from time to time by the Board.

     (f) INDEMNIFICATION. With respect to Executive's acts or failures to act
during the Employment Period in his capacity as a director, officer, employee or
agent of the Company, Executive shall be entitled to indemnification from the
Company, and to liability insurance coverage (if any), on the same basis as
other directors and officers of the Company.

     4. ADJUSTMENTS. Notwithstanding any other provision of this Agreement, it
is expressly understood and agreed that if there is a significant reduction in
the level of the business to which Executive's duties under this Agreement
relate, or if all or any significant part of such business is disposed of by the
Company and/or its subsidiaries or affiliates during the Employment Period but
Executive thereafter remains an employee of the Company, the Compensation
Committee of the Board (or, if there is no such Committee, the Board) may make
adjustments in Executive's duties, responsibility and authority, and in
Executive's compensation, as the Compensation Committee of the Board (or, if
there is no such Committee, the Board) deems appropriate to reflect such
reduction or disposition.

     5. EMPLOYMENT PERIOD.

     (a) Except as hereinafter provided, the Employment Period shall continue
until, and shall end upon, the second anniversary of the date on which the
Employment Period begins.

     (b) On each anniversary of the date on which the Employment Period begins
which precedes Executive's sixty-fifth birthday by more than one year, unless
the Employment Period shall have ended early pursuant to (c) below or either
party shall have given the other party written notice that the extension
provision in this sentence shall no longer apply, the Employment Period shall be
extended for an additional year (unless Executive's sixty-fifth birthday occurs
during such additional year, in which event the Employment Period shall be
extended only until such birthday). In no event shall the Employment Period be
extended beyond Executive's sixty-fifth birthday except by mutual written
agreement of the Company and Executive.

     (c) Notwithstanding (a) and (b) above, the Employment Period shall end
early upon the first to occur of any of the following events:

     (i) Executive's death;

     (ii) Executive's retirement upon or after reaching age 65 ("RETIREMENT");

period of more than six (6) consecutive months ("TERMINATION FOR DISABILITY");

     (iv) the Company's termination of Executive's employment for Cause
("TERMINATION FOR CAUSE");


<PAGE>   4

          termination as a Termination by Executive for Good Reason and
          identifying the Good Reason ("TERMINATION BY EXECUTIVE FOR GOOD
          REASON") (it being expressly understood that Executive's giving notice
          that the extension provision in the first sentence of paragraph 5(b)
          hereof shall no longer apply shall not constitute a Termination by
          Executive for Good Reason);

    (vii) Executive's termination of Executive's employment for any reason
          other than Good Reason, by means of advance written notice to the
          Company at least one hundred twenty (120) days prior to the effective
          date of such termination identifying such termination as a Termination
          by Executive with Advance Notice ("TERMINATION BY EXECUTIVE WITH
          ADVANCE NOTICE") (it being expressly understood that Executive's
          giving notice that the extension provision in the first sentence of
          paragraph 5(b) hereof shall no longer apply shall not constitute a
          Termination by Executive with Advance Notice); or

   (viii) the termination of Executive's employment (A) on account of a
          Termination without Cause before the second anniversary of a Change of
          Control, (B) on account of a Termination by Executive for Good Reason
          before the second anniversary of a Change of Control or (C) in
          connection with but prior to a Change of Control and following the
          commencement of any discussion with any third party that (i) requests
          or suggests that Executive's employment be terminated, and (ii)
          ultimately engages in a Change of Control (collectively, "TERMINATION
          FOLLOWING A CHANGE OF CONTROL").
   
      (d) For purposes of this Agreement, "CAUSE" shall mean:

     (i)  the commission by Executive of a felony or a crime involving moral
          turpitude;

     (ii) the commission by Executive of a fraud;

     (iii) the commission by Executive of any act involving dishonesty or
          disloyalty with respect to the Company or any of its subsidiaries or

          of his employment with the Company (it being expressly understood that
          a Termination by Executive for Good Reason or a Termination by

          or abandonment);

    (vii) breach by Executive of any of the agreements in paragraph 8 hereof
          prior to the end of the Employment Period; or

   (viii) any other breach by Executive of this Agreement which is material
          and which is not cured within thirty (30) days after written notice
          thereof to Executive from the Company.

          paragraph 5(b) hereof, Executive's salary on the date on which the
          most recent such extension occurred) or any downward adjustment in
          Executive's Target Bonus; or

     (ii) the Company's giving notice that the extension provision in the first
          sentence of paragraph 5(b) hereof shall no longer apply; or

either: (A) the then-outstanding shares of common stock of the Company (the

voting securities entitled to vote generally in the election of directors, as
the case may be, of the entity resulting from such Business Combination
(including, without limitation, an entity which as a result of such transaction

<PAGE>   7

representing more than fifty percent (50%) of the total value of the stock or

     6. POST-EMPLOYMENT PERIOD PAYMENTS.

     (a) If the Employment Period ends on the date on which (without any
extension thereof) it is then scheduled to end pursuant to paragraph 5 hereof,
or if the Employment Period ends early pursuant to paragraph 5 hereof for any
reason, Executive shall cease to have any rights to salary, bonus (if any),
options, expense reimbursements or other benefits other than: (i) any salary
which has accrued but is unpaid, any reimbursable expenses which have been
incurred but are unpaid, and any unexpired vacation days which have accrued
under the Company's vacation policy but are unused, as of the end of the
Employment Period, (ii) any option rights or plan benefits which by their terms
extend beyond termination of Executive's employment (but only to the extent
provided in any option theretofore granted to Executive or any benefit plan in
which Executive has participated as an employee of the Company), (iii) any
benefits to which Executive is entitled under Part 6 of Subtitle B of Title I of
the Employee Retirement Income Security Act of 1974, as amended ("COBRA") and
(iv) any other amount(s) payable pursuant to the succeeding provisions of this

     (b) If the Employment Period ends pursuant to paragraph 5 hereof on
Executive's sixty-fifth birthday, or if the Employment Period ends early

(provided such Retirement is not a Termination Following a Change of Control) or
Termination for Disability, the Company shall make no further payments to
Executive except as contemplated in (a)(i), (ii) and (iii) above.

     (c) If the Employment Period ends early pursuant to paragraph 5 hereof on
account of Termination for Cause, the Company shall pay Executive an amount
equal to that amount Executive would have received as salary (based on
Executive's salary then in effect) had the Employment Period remained in effect
until the later of the effective date of the Company's termination of
Executive's employment or the date thirty days after the Company's notice to
Executive of such termination. The Company shall make no further payments to
Executive except as contemplated in (a)(i), (ii) and (iii) above.

     (d) If the Employment Period ends early pursuant to paragraph 5 hereof on
account of a Termination without Cause or a Termination by Executive for Good
Reason, and such termination does not constitute a Termination Following a

amounts Executive would have received as salary (based on Executive's salary
then in effect or, if greater, Executive's Reference Salary) had the Employment
Period remained in effect for a period of twenty-four (24) months after the last
day of the month in which the Employment Period ends (in the event Executive is
entitled during the payment period to any payments under any disability benefit
plan or the like in which Executive has participated as an employee of the
Company, less such payments), payable at the times such amounts would have been
paid; PROVIDED, HOWEVER, that if Executive so chooses, in his sole discretion,
such payment under this subparagraph (d) shall be made in a lump sum. In
addition, the Company shall reimburse Executive (net after taxes on the receipt
of such reimbursement) for any premiums paid by Executive for health insurance
provided to Executive (for Executive and his dependents) by the Company
subsequent to the end of the Employment Period pursuant to the requirements of
COBRA as in effect on the date of this Agreement. The Company shall make no
further payments to Executive except as contemplated in (a)(i), (ii) and (iii)
above. It is expressly understood that the Company's payment


<PAGE>   8



obligations under this subparagraph (d) shall cease in the event Executive
breaches any of his agreements in paragraph 7 or 8 hereof.

     (e) If the Employment Period ends early pursuant to paragraph 5 hereof on
account of a Termination by Executive with Advance Notice, and such termination
does not constitute a Termination Following a Change of Control, the Company
shall make no further payments to Executive except as contemplated in (a)(i),
(ii) and (iii) above.

   (f)(i) If the Employment Period ends early pursuant to paragraph 5 hereof
          on account of a Termination Following a Change of Control, Executive
          shall be entitled to receive an amount equal to two times the sum of
          (A) Executive's base salary at the time of such termination (or, if
          higher, Executive's Reference Salary) and (B) Executive's Target Bonus
          for the year in which such termination occurs (or, if higher,
          Executive's Target Bonus for the preceding year or the year in which
          the Change of Control occurs), payable at the times such amounts would
          have been paid; PROVIDED, HOWEVER, that if Executive so chooses, in
          his sole discretion, such payment under this subparagraph (f)(i) shall
          be made in a lump sum. In addition, the Company shall reimburse
          Executive (net after taxes on the receipt of such reimbursement) for
          any premiums paid by Executive for health insurance provided to
          Executive (for Executive and his dependents) by the Company subsequent
          to the end of the Employment Period pursuant to the requirements of
          COBRA as in effect on the date of this Agreement.

     (ii) Notwithstanding any provision of this Agreement to the contrary, if
          any amount or benefit to be paid or provided under this Agreement or
          otherwise pursuant to or by reason of any other agreement, policy,
          plan, program or arrangement, including without limitation any bonus,
          stock option, performance share, performance unit, stock appreciation
          right or similar right, or the lapse or termination of any restriction
          on or the vesting or exercisability of any of the foregoing would be
          an "Excess Parachute Payment," within the meaning of Section 280G of
          the Code, or any successor provision thereto, but for the application
          of this sentence, then the payments and benefits to be paid or
          provided under this Agreement shall be reduced to the minimum extent
          necessary (but in no event to less than zero) so that no portion of
          any such payment or benefit, as so reduced, constitutes an Excess
          Parachute Payment; provided, however, that the foregoing reduction
          shall be made only if and to the extent that such reduction would
          result in an increase in the aggregate payment and benefits to be
          provided to Executive, determined on an after-tax basis (taking into
          account the excise tax imposed pursuant to Section 4999 of the Code,
          or any successor provision thereto, any tax imposed by any comparable
          provision of state law, and any applicable federal, state and local
          income taxes). The determination of whether any reduction in such
          payments or benefits to be provided under this Agreement is required
          pursuant to the preceding sentence shall be made at the expense of the
          Company, if requested by the Executive or the Company, by the
          Company's independent accountants. The fact that the Executive's right
          to payments or benefits may be reduced by reason of the limitations
          contained in this paragraph 6(f) shall not of itself limit or
          otherwise affect any other rights of the Executive other than pursuant
          to this Agreement. In the event


<PAGE>   9



                    that any payment or benefit intended to be provided under
                    this Agreement is required to be reduced pursuant to this
                    paragraph 6(f), the Executive shall be entitled to designate
                    the payments and/or benefits to be so reduced in order to
                    give effect to this paragraph 6(f). The Company shall
                    provide the Executive with all information reasonably
                    requested by the Executive to permit the Executive to make
                    such designation. In the event that the Executive fails to
                    make such designation within 10 business days of the Date of
                    Termination, the Company may effect such reduction in any
                    manner it deems appropriate.

          (g) Without limiting the rights of the Executive at law or in equity,
     if the Company fails to make any payment or provide any benefit required to
     be made or provided hereunder on a timely basis, the Company will pay
     interest on the amount or value thereof at an annualized rate of interest
     equal to the so-called composite "prime rate" as quoted from time to time
     during the relevant period in the Midwest Edition of THE WALL STREET
     JOURNAL. Such interest will be payable as it accrues on demand. Any change
     in such prime rate will be effective on and as of the date of such change.

          (h) Executive shall not be required to mitigate the amount of any
     payment or benefit provided for in this Agreement by seeking other
     employment or otherwise.

          7. CONFIDENTIAL INFORMATION. Executive acknowledges that the
     information, observations and data obtained by him while employed by the
     Company pursuant to this Agreement, as well as those obtained by him while
     employed by the Company or any of its subsidiaries or affiliates or any
     predecessor thereof prior to the date of this Agreement, concerning the
     business or affairs of the Company or any of its subsidiaries or affiliates
     or any predecessor thereof (unless and except to the extent the foregoing
     become generally known to and available for use by the public other than as
     a result of Executive's acts or omissions to act, "CONFIDENTIAL
     INFORMATION") are the property of the Company or such subsidiary or
     affiliate. Therefore, Executive agrees that during the Employment Period
     and for two years thereafter he shall not disclose any Confidential
     Information without the prior written consent of the Chief Executive
     Officer of the Company unless and except to the extent that such disclosure
     is (i) made in the ordinary course of Executive's performance of his duties
     under this Agreement or (ii) required by any subpoena or other legal
     process (in which event Executive will give the Company prompt notice of
     such subpoena or other legal process in order to permit the Company to seek
     appropriate protective orders), and that he shall not use any Confidential
     Information for his own account without the prior written consent of the
     Chief Executive Officer of the Company. Executive shall deliver to the
     Company at the termination of the Employment Period, or at any other time
     the Company may reasonably request, all memoranda, notes, plans, records,
     reports, computer tapes and software and other documents and data (and
     copies thereof) relating to the Confidential Information, or to the work
     product or the business of the Company or any of its subsidiaries or
     affiliates which he may then possess or have under his control.


<PAGE>   10



     8. NON-COMPETE, NON-SOLICITATION.

          (a) Executive acknowledges that in the course of his employment with
     the Company pursuant to this Agreement he will become familiar, and during
     the course of his employment by the Company or any of its subsidiaries or
     affiliates or any predecessor thereof prior to the date of this Agreement
     he has become familiar, with trade secrets and customer lists of and other
     confidential information concerning the Company and its subsidiaries and
     affiliates and predecessors thereof and that his services have been and
     will be of special, unique and extraordinary value to the Company.

          (b) Executive agrees that during the Employment Period and for a
     period of two years after termination of his employment with the Company,
     he shall not in any manner, directly or indirectly, through any person,
     firm or corporation, alone or as a member of a partnership or as an
     officer, director, shareholder, investor or employee of or in any other
     corporation or enterprise or otherwise, engage in or be engaged in, or
     assist any other person, firm, corporation or enterprise in engaging or
     being engaged in, any business then actively being conducted by the Company
     or any of its subsidiaries or affiliates.

          (c) Executive further agrees that during the Employment Period and for
     a period of two years after termination of his employment with the Company,
     he shall not in any manner, directly or indirectly, induce or attempt to
     induce any employee of the Company or of any of its subsidiaries or
     affiliates to quit or abandon his employ.

          (d) Nothing in this paragraph 8 shall prohibit Executive from being:
     (i) a shareholder in a mutual fund or a diversified investment company or
     (ii) a passive owner of not more than 5% of the outstanding equity
     securities of any class of a corporation or other entity which is publicly
     traded, so long as Executive has no active participation in the business of
     such corporation or other entity.

          (e) If, at the time of enforcement of this paragraph, a court holds
     that the restrictions stated herein are unreasonable under circumstances
     then existing, the parties hereto agree that the maximum period, scope or
     geographical area reasonable under such circumstances shall be substituted
     for the stated period, scope or area and that the court shall be allowed to
     revise the restrictions contained herein to cover the maximum period, scope
     and area permitted by law.

          9. ENFORCEMENT. Because Executive's services are unique and because
     Executive has access to Confidential Information and work product, the
     parties hereto agree that the Company would be damaged irreparably in the
     event any of the provisions of paragraph 8 hereof were not performed in
     accordance with their specific terms or were otherwise breached and that
     money damages would be an inadequate remedy for any such non-performance or
     breach. Therefore, the Company or its successors or assigns shall be
     entitled, in addition to other rights and remedies existing in their favor,
     to an injunction or injunctions to prevent any breach or threatened breach
     of any of such provisions and to enforce such provisions specifically
     (without posting a bond or other security).

          10. EXECUTIVE REPRESENTATIONS. Executive represents and warrants to
     the Company that (i) the execution, delivery and performance of this
     Agreement by Executive does not and will not conflict with, breach, violate
     or cause a default under any contract, agreement, instrument, order,
     judgment or decree to which Executive is a party or by which he is bound,
     (ii) Executive is not a party to or bound by any employment agreement,
     noncompete agreement or


<PAGE>   11


confidentiality agreement with any other person or entity, and (iii) upon the
execution and delivery of this Agreement by the Company, this Agreement shall be
the valid and binding obligation of Executive, enforceable in accordance with
its terms.

          11. SURVIVAL. Subject to any limits on applicability contained
     therein, paragraphs 7 and 8 hereof shall survive and continue in full force
     in accordance with their terms notwithstanding any termination of the
     Employment Period.

          12. NOTICES. Any notice provided for in this Agreement shall be in
     writing and shall be either personally delivered, sent by reputable
     overnight carrier or mailed by first class mail, return receipt requested,
     to the recipient at the address below indicated:

party shall have specified by prior written notice to the sending party. Any
notice under this Agreement will be deemed to have been given when so delivered,
sent or mailed.

          13. SEVERABILITY. Whenever possible, each provision of this Agreement
     shall be interpreted in such manner as to be effective and valid under
     applicable law, but if any provision of this Agreement is held to be
     invalid, illegal or unenforceable in any respect under any applicable law
     or rule in any jurisdiction, such invalidity, illegality or
     unenforceability shall not affect any other provision or any other
     jurisdiction, but this Agreement shall be reformed, construed and enforced
     in such jurisdiction as if such invalid, illegal or unenforceable provision
     had never been contained herein.

          14. PAYMENT OF CERTAIN COSTS AND EXPENSES.

          (a) PREVAILING PARTY'S LITIGATION EXPENSES. In the event of litigation
     between the Company and Executive related to this Agreement, the
     non-prevailing party shall reimburse the prevailing party for any costs and
     expenses (including without limitation attorneys' fees) reasonably incurred
     by the prevailing party in connection therewith.

          (b) CHANGE OF CONTROL OF THE COMPANY. Without limiting the generality
     of (a) above, in the event that there is a Change of Control of the
     Company, if it should appear to Executive that the Company has failed to
     comply with any of its obligations under this Agreement or in the event
     that the Company or any other person takes or threatens to take any action
     to declare this Agreement void or unenforceable, or institutes any
     litigation or other action or proceeding


<PAGE>   12



designed to deny, or to recover from, Executive the benefits provided or
intended to be provided to Executive hereunder, the Company irrevocably
authorizes Executive from time to time to retain counsel of Executive's choice,
at the expense of the Company as hereafter provided, to advise and represent
Executive in connection with any such interpretation, enforcement or defense,
including without limitation the initiation or defense of any litigation or
other legal action, whether by or against the Company or any Director, officer,
shareholder or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to Executive's
entering into an attorney-client relationship with such counsel, and in that
connection the Company and Executive agree that a confidential relationship will
exist between Executive and such counsel. Without respect to whether Executive
prevails, in whole or in part, in connection with any of the foregoing, the
Company will pay and be solely financially responsible for any and all
attorneys' and related fees and expenses incurred by Executive in connection
with any of the foregoing.

     (c) SOURCE OF PAYMENTS. Except as otherwise specified herein, in the event
a Change of Control occurs, any payments to Executive pursuant to this Agreement
and the performance of the Company's obligations hereunder shall be secured by
amounts deposited or to be deposited in a trust established by the Company for
the benefit of Executive (and, at the Company's option, for the benefit of other
executives of the Company who are entitled to payments similar to those provided
in this Agreement) (the "Trust"). The Company shall transfer to such Trust
assets from which all or a portion of the payments provided under this Agreement
are to be paid, provided that such assets of the Trust shall at all times be
subject to the claims of general unsecured creditors of the Company and that
neither Executive nor any other person entitled to payments through the Trust
shall at any time have a prior claim to such assets. Any payments to Executive
under this Agreement that are not paid through the Trust shall be paid from the
Company's general assets, and Executive shall have the status of a general
unsecured creditor with respect to the Company's obligations to make payments
under this Agreement.

     15. COMPLETE AGREEMENT. This Agreement embodies the complete agreement and
understanding between the parties with respect to the subject matter hereof and
effective as of its date supersedes and preempts any prior understandings,
agreements or representations by or between the parties, written or oral, which
may have related to the subject matter hereof in any way.

     16. COUNTERPARTS. This Agreement may be executed in separate counterparts,
each of which shall be deemed to be an original and both of which taken together
shall constitute one and the same agreement.

     17. SUCCESSORS AND ASSIGNS. This Agreement shall bind and inure to the
benefit of and be enforceable by Executive, the Company and their respective
heirs, executors, personal representatives, successors and assigns, except that
neither party may assign any of his or its rights or delegate any of his or its
obligations hereunder without the prior written consent of the other party.
Executive hereby consents to the assignment by the Company of all of its rights
and obligations hereunder to any successor to the Company by merger or
consolidation or purchase of all or substantially all of the Company's assets,
provided such transferee or successor assumes the liabilities of the Company
hereunder.

     18. CHOICE OF LAW. This Agreement shall be governed by the internal law,
and not the laws of conflicts, of the State of Ohio.

     19. AMENDMENT AND WAIVER. The provisions of this Agreement may be amended
or waived only with the prior written consent of the Company and Executive, and
no course of conduct or failure or delay in enforcing the provisions of this
Agreement shall affect the validity, binding effect or enforceability of this
Agreement.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date written below.

                              EMPLOYMENT AGREEMENT
                              --------------------

     This EMPLOYMENT AGREEMENT ("AGREEMENT") made as of January 1, 1999, between
Penton Media, Inc. (formerly known as Penton Publishing, Inc.), a Delaware
corporation (the "COMPANY"), and James W. Zaremba ("EXECUTIVE")

     In consideration of the mutual covenants contained herein and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

     1. EMPLOYMENT. The Company shall employ Executive, and Executive accepts
continued employment with the Company as of the date hereof, upon the terms and
conditions set forth in this Agreement for the period beginning on the date
hereof and ending as provided in paragraph 5 hereof (the "EMPLOYMENT PERIOD").

     2.   POSITION AND DUTIES.

     (a) During the Employment Period, Executive shall serve as a Group
President of the Company, with initial responsibility for the Company's
Design/Engineering, Foodservice/Hospitality, Manufacturing Groups, and
A/E/C/SYSTEMS (the "Division"), and shall have the normal duties,
responsibilities and authority of an executive serving in such position, subject
to the power of the Board of Directors of the Company (the "BOARD") or the Chief
Executive Officer of the Company to expand or limit such duties,
responsibilities and authority, either generally or in specific instances.

     (b) Executive shall report to the Chief Executive Officer or the President
and Chief Operating Officer of the Company.

     (c) During the Employment Period, Executive shall devote his best efforts
and his full business time and attention (except for permitted vacation periods,
reasonable periods of illness or other incapacity, and, provided such activities
do not have more than a DE MINIMIS effect on Executive's performance of his
duties under this Agreement, participation in charitable and civic endeavors and
management of Executive's personal investments and business interests) to the
business and affairs of the Company and the Division. Executive shall perform
his duties and responsibilities to the best of his abilities in a diligent,
trustworthy, businesslike and efficient manner.

     (d) Executive shall perform his duties and responsibilities principally in
the Cleveland, Ohio metropolitan area, and shall not be required to travel
outside that area any more extensively than he has done in the past in the
ordinary course of the business of the Company.

     3. COMPENSATION AND BENEFITS.

     (a) SALARY. The Company agrees to pay Executive a salary during the
Employment Period, in semi-monthly installments. Executive's initial salary
shall be $265,000 per year. The Compensation Committee of the Board (or, if
there is no such Committee, the Board) shall review Executive's salary from time
to time and may, in its sole discretion, increase it.

     (b) BONUS(ES). Effective January 1, 1999 and for subsequent years,
Executive will be eligible for an annual bonus based on the achievement of
specified Company goals (the "Target Bonus") (as determined by the Compensation
Committee of the Board (or, if there is no such Committee, the Board)). Any
bonus payable pursuant to this subparagraph (b) may, at the discretion of the
Compensation Committee of the Board (or, if there is no such Committee, the
Board), after considering any preference expressed by Executive, be paid in the
form of cash, in a Performance Shares Award related to shares of the Company's
Common Stock or in a combination of both.

     (c) STOCK OPTIONS. The Company has adopted a plan (the "1998 STOCK OPTION
PLAN") pursuant to which options to purchase shares of the Company's Common
Stock, and other equity-based incentive compensation awards, may be granted to
Executive and other officers of the Company. Executive shall be eligible to
receive grants of options and other awards under the 1998 Stock Option Plan, at
the discretion of the Compensation Committee of the Board (or, if there is no
such Committee, the Board). Under the terms of the 1998 Stock Option Plan, the
Compensation Committee of the Board (or, if there is no such Committee, the
Board) has the right to amend the 1998 Stock Option Plan. If, at the time of the
grant of any option pursuant to this paragraph (c), the issuance of shares upon
exercise thereof has not been registered under the Securities Act of 1933, as
amended, it shall be a condition to such grant that Executive execute and
deliver to the Company a certificate confirming that Executive is an accredited
investor (as such term is used in Regulation D under such Act) and including
transfer restrictions and other provisions customary in connection with grants
under such circumstances. Each option to be granted as set forth above shall be
substantially in the form of EXHIBIT 1 attached to this Agreement, except that
it is understood that reference to any then existing registration statement or
related plan information document in EXHIBIT 1, or its equivalent, shall be
included if and only if the same exists at the time of grant and is relevant to
such option.

     (d) EXPENSE REIMBURSEMENT. The Company shall reimburse Executive for all
reasonable expenses incurred by him during the Employment Period in the course
of performing his duties under this Agreement that are consistent with the
Company's policies in effect from time to time with respect to travel,
entertainment and other business expenses, subject to the Company's requirements
applicable generally with respect to reporting and documentation of such
expenses. Executive acknowledges that under the Company's current air travel
reimbursement policy, reimbursement is limited to coach fare (plus Executive's
cost of any upgrade certificates used to upgrade to first class) on travel
within the United States and is limited to business class fare on travel to and
from foreign cities.

     (e) STANDARD EXECUTIVE BENEFITS PACKAGE. In addition to the salary,
bonus(es), stock options and expense reimbursements payable to Executive
pursuant to this paragraph, Executive shall be entitled during the Employment
Period to participate, on the same basis as other

<PAGE>   3

executives of the Company, in the Company's Standard Executive Benefits Package.
The Company's "STANDARD EXECUTIVE BENEFITS PACKAGE" means those benefits
(including insurance, vacation, Company car or car allowance, equity-based
benefits, and other benefits) for which substantially all of the executives of
the Company are from time to time generally eligible, as determined from time to
time by the Board.

     (f) INDEMNIFICATION. With respect to Executive's acts or failures to act
during the Employment Period in his capacity as a director, officer, employee or
agent of the Company, Executive shall be entitled to indemnification from the
Company, and to liability insurance coverage (if any), on the same basis as
other directors and officers of the Company.

     4. ADJUSTMENTS. Notwithstanding any other provision of this Agreement, it
is expressly understood and agreed that if there is a significant reduction in
the level of the business to which Executive's duties under this Agreement
relate, or if all or any significant part of such business is disposed of by the
Company and/or its subsidiaries or affiliates during the Employment Period but
Executive thereafter remains an employee of the Company, the Compensation
Committee of the Board (or, if there is no such Committee, the Board) may make
adjustments in Executive's duties, responsibility and authority, and in
Executive's compensation, as the Compensation Committee of the Board (or, if
there is no such Committee, the Board) deems appropriate to reflect such
reduction or disposition.

     5. EMPLOYMENT PERIOD.

     (a) Except as hereinafter provided, the Employment Period shall continue
until, and shall end upon, the second anniversary of the date on which the
Employment Period begins.

     (b) On each anniversary of the date on which the Employment Period begins
which precedes Executive's sixty-fifth birthday by more than one year, unless
the Employment Period shall have ended early pursuant to (c) below or either
party shall have given the other party written notice that the extension
provision in this sentence shall no longer apply, the Employment Period shall be
extended for an additional year (unless Executive's sixty-fifth birthday occurs
during such additional year, in which event the Employment Period shall be
extended only until such birthday). In no event shall the Employment Period be
extended beyond Executive's sixty-fifth birthday except by mutual written
agreement of the Company and Executive.

     (c) Notwithstanding (a) and (b) above, the Employment Period shall end
early upon the first to occur of any of the following events:

     (i) Executive's death;

<PAGE>   4

          for a period of more than six (6) consecutive months ("TERMINATION FOR

     (iv) the Company's termination of Executive's employment for Cause
          ("TERMINATION FOR CAUSE");

          WITHOUT CAUSE");

     (vi) Executive's termination of Executive's employment for Good Reason, by
          means of advance written notice to the Company at least thirty (30)
          days prior to the effective date of such termination identifying such
          termination as a Termination by Executive for Good Reason and
          identifying the Good Reason ("TERMINATION BY EXECUTIVE FOR GOOD
          REASON") (it being expressly understood that Executive's giving notice
          that the extension provision in the first sentence of paragraph 5(b)
          hereof shall no longer apply shall not constitute a Termination by
          Executive for Good Reason);

     (vii)Executive's termination of Executive's employment for any reason
          other than Good Reason, by means of advance written notice to the
          Company at least one hundred twenty (120) days prior to the effective
          date of such termination identifying such termination as a Termination
          by Executive with Advance Notice ("TERMINATION BY EXECUTIVE WITH
          ADVANCE NOTICE") (it being expressly understood that Executive's
          giving notice that the extension provision in the first sentence of
          paragraph 5(b) hereof shall no longer apply shall not constitute a
          Termination by Executive with Advance Notice); or

     (viii) the termination of Executive's employment (A) on account of a
          Termination without Cause before the second anniversary of a Change of
          Control, (B) on account of a Termination by Executive for Good Reason
          before the second anniversary of a Change of Control or (C) in
          connection with but prior to a Change of Control and following the
          commencement of any discussion with any third party that (i) requests
          or suggests that Executive's employment be terminated, and (ii)
          ultimately engages in a Change of Control (collectively, "TERMINATION
          FOLLOWING A CHANGE OF CONTROL").

     (d) For purposes of this Agreement, "CAUSE" shall mean:

     (i)  the commission by Executive of a felony or a crime involving moral
          turpitude;

     (ii) the commission by Executive of a fraud;

<PAGE>   5

     (iii)the commission by Executive of any act involving dishonesty or

          affiliates that harms or damages any of them to any extent;

     (iv) conduct by Executive that brings the Company or any of its

          the Company or any of its subsidiaries or affiliates;

     (vi) repudiation of this Agreement by Executive or Executive's abandonment
          of his employment with the Company (it being expressly understood that
          a Termination by Executive for Good Reason or a Termination by
          Executive with Advance Notice shall not constitute such a repudiation
          or abandonment);

     (vii)breach by Executive of any of the agreements in paragraph 8 hereof
          prior to the end of the Employment Period; or

     (viii) any other breach by Executive of this Agreement which is material
          and which is not cured within thirty (30) days after written notice
          thereof to Executive from the Company.

     (e) For purposes of this Agreement, "GOOD REASON" shall mean:

     (i)  a reduction by the Company in Executive's salary to an amount less
          than "EXECUTIVE'S REFERENCE SALARY" (i.e., Executive's initial salary
          or, in the event the Employment Period has been extended pursuant to
          paragraph 5(b) hereof, Executive's salary on the date on which the
          most recent such extension occurred) or any downward adjustment in
          Executive's Target Bonus; or

     (ii) the Company's giving notice that the extension provision in the first
          sentence of paragraph 5(b) hereof shall no longer apply; or

          occurrence of any of the following events during the Employment
          Period:

     (i)  The acquisition by any individual, entity or group (within the meaning
          of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
          1934, as amended (the "Exchange Act")) (a "Person") of beneficial
          ownership (within the meaning of Rule 13d-3 promulgated under the
          Exchange Act) of 40% or more of either: (A) the then-outstanding
          shares of common stock of the Company (the "Company Common Stock") or
          (B) the combined voting

<PAGE>   6

          power of the then-outstanding voting securities of the Company
          entitled to vote generally in the election of directors ("Voting
          Stock"); PROVIDED, HOWEVER, that for purposes of this subparagraph
          (i), the following acquisitions shall not constitute a Change of
          Control: (A) any acquisition directly from the Company, (B) any
          acquisition by the Company, a subsidiary of the Company or the Harris
          Group, (C) any acquisition by any employee benefit plan (or related
          trust) sponsored or maintained by the Company or any subsidiary of the
          Company, or (D) any acquisition by any Person pursuant to a
          transaction which complies with clauses (A), (B) and (C) of
          subparagraph (iii) of this paragraph 5(f); or

               (ii) Individuals who, as of the date hereof, constitute the Board
          (the "Incumbent Board") cease for any reason (other than death or
          disability) to constitute at least a majority of the Board; PROVIDED,
          HOWEVER, that any individual becoming a director subsequent to the
          date hereof whose election, or nomination for election by the
          Company's shareholders, was approved by a vote of at least a majority
          of the directors then comprising the Incumbent Board (either by a
          specific vote or by approval of the proxy statement of the Company in
          which such person is named as a nominee for director, without
          objection to such nomination) shall be considered as though such
          individual were a member of the Incumbent Board, but excluding for
          this purpose, any such individual whose initial assumption of office
          occurs as a result of an actual or threatened election contest (within
          the meaning of Rule 14a-11 of the Exchange Act) with respect to the
          election or removal of directors or other actual or threatened
          solicitation of proxies or consents by or on behalf of a Person other
          than the Board; or

               (iii) Consummation of a reorganization, merger or consolidation
          or sale or other disposition of all or substantially all of the assets
          of the Company (a "Business Combination"), in each case, unless,
          following such Business Combination, (A) all or substantially all of
          the individuals and entities who were the beneficial owners,
          respectively, of the Company Common Stock and Voting Stock immediately
          prior to such Business Combination beneficially own, directly or
          indirectly, more than a majority of, respectively, the
          then-outstanding shares of common stock and the combined voting power
          of the then-outstanding voting securities entitled to vote generally
          in the election of directors, as the case may be, of the entity
          resulting from such Business Combination (including, without
          limitation, an entity which as a result of such transaction owns the
          Company or all or substantially all of the Company's assets either
          directly or through one or more subsidiaries) in substantially the
          same proportions relative to each other as their ownership,
          immediately prior to such Business Combination, of the Company Common
          Stock and Voting Stock of the Company, as the case may be, (B) no
          Person (excluding any entity resulting from such Business Combination,
          the Harris Group or any employee benefit plan (or related trust)
          sponsored or maintained by the Company, a subsidiary of the Company or
          such entity resulting from such Business Combination) beneficially
          owns, directly or indirectly, 40% or more of, respectively, the
          then-outstanding shares of common stock of the entity resulting from
          such Business Combination, or the combined voting power of the
          then-outstanding voting securities of such corporation except to the
          extent that such ownership existed prior to the Business Combination
          and (C) at least a majority of the members of the board of directors
          of the corporation resulting from such Business Combination were
          members of the

<PAGE>   7

          Incumbent Board at the time of the execution of the initial agreement,
          or of the action of the Board, providing for such Business
          Combination; or

               (iv) Approval by the shareholders of the Company of a complete
          liquidation or dissolution of the Company.

               (v) For purposes of this paragraph 5(f), the "Harris Group" shall
          mean Messrs. Irving B. Harris, Neison Harris, King Harris, William W.
          Harris and June H. Barrows, and their respective spouses, descendants
          and spouses of descendants, trustees of trusts established for the
          benefit of such persons (acting in their capacity as trustees of such
          trusts), and executors of estates of such persons (acting in their
          capacity as executors of such estates), and each person of which any
          of the foregoing owns (i) more than fifty percent (50%) of the voting
          stock or other voting interests and (ii) stock or other interests
          representing more than fifty percent (50%) of the total value of the

               6. POST-EMPLOYMENT PERIOD PAYMENTS.

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

               (a) If the Employment Period ends on the date on which (without
          any extension thereof) it is then scheduled to end pursuant to
          paragraph 5 hereof, or if the Employment Period ends early pursuant to
          paragraph 5 hereof for any reason, Executive shall cease to have any
          rights to salary, bonus (if any), options, expense reimbursements or
          other benefits other than: (i) any salary which has accrued but is
          unpaid, any reimbursable expenses which have been incurred but are
          unpaid, and any unexpired vacation days which have accrued under the
          Company's vacation policy but are unused, as of the end of the
          Employment Period, (ii) any option rights or plan benefits which by
          their terms extend beyond termination of Executive's employment (but
          only to the extent provided in any option theretofore granted to
          Executive or any benefit plan in which Executive has participated as
          an employee of the Company), (iii) any benefits to which Executive is
          entitled under Part 6 of Subtitle B of Title I of the Employee
          Retirement Income Security Act of 1974, as amended ("COBRA") and (iv)
          any other amount(s) payable pursuant to the succeeding provisions of
          this paragraph 6.

               (b) If the Employment Period ends pursuant to paragraph 5 hereof
          on Executive's sixty-fifth birthday, or if the Employment Period ends
          early pursuant to paragraph 5 hereof on account of Executive's death,
          Retirement (provided such Retirement is not a Termination Following a
          Change of Control) or Termination for Disability, the Company shall
          make no further payments to Executive except as contemplated in
          (a)(i), (ii) and (iii) above.

               (c) If the Employment Period ends early pursuant to paragraph 5
          hereof on account of Termination for Cause, the Company shall pay
          Executive an amount equal to that amount Executive would have received
          as salary (based on Executive's salary then in effect) had the
          Employment Period remained in effect until the later of the effective
          date of the Company's termination of Executive's employment or the
          date thirty days after the Company's notice to Executive of such
          termination. The Company shall make no further payments to Executive
          except as contemplated in (a)(i), (ii) and (iii) above.

<PAGE>   8

               (d) If the Employment Period ends early pursuant to paragraph 5
          hereof on account of a Termination without Cause or a Termination by
          Executive for Good Reason, and such termination does not constitute a
          Termination Following a Change of Control, the Company shall pay to
          Executive amounts equal to the amounts Executive would have received
          as salary (based on Executive's salary then in effect or, if greater,
          Executive's Reference Salary) had the Employment Period remained in
          effect for a period of twenty-four (24) months after the last day of
          the month in which the Employment Period ends (in the event Executive
          is entitled during the payment period to any payments under any
          disability benefit plan or the like in which Executive has
          participated as an employee of the Company, less such payments),
          payable at the times such amounts would have been paid; PROVIDED,
          HOWEVER, that if Executive so chooses, in his sole discretion, such
          payment under this subparagraph (d) shall be made in a lump sum. In
          addition, the Company shall reimburse Executive (net after taxes on
          the receipt of such reimbursement) for any premiums paid by Executive
          for health insurance provided to Executive (for Executive and his
          dependents) by the Company subsequent to the end of the Employment
          Period pursuant to the requirements of COBRA as in effect on the date
          of this Agreement. The Company shall make no further payments to
          Executive except as contemplated in (a)(i), (ii) and (iii) above. It
          is expressly understood that the Company's payment obligations under
          this subparagraph (d) shall cease in the event Executive breaches any
          of his agreements in paragraph 7 or 8 hereof.

               (e) If the Employment Period ends early pursuant to paragraph 5
          hereof on account of a Termination by Executive with Advance Notice,
          and such termination does not constitute a Termination Following a
          Change of Control, the Company shall make no further payments to
          Executive except as contemplated in (a)(i), (ii) and (iii) above.

               (f)(i)  If the Employment Period ends early pursuant to paragraph
                       5 hereof on account of a Termination Following a Change
                       of Control, Executive shall be entitled to receive an
                       amount equal to two times the sum of (A) Executive's base
                       salary at the time of such termination (or, if higher,
                       Executive's Reference Salary) and (B) Executive's Target
                       Bonus for the year in which such termination occurs (or,
                       if higher, Executive's Target Bonus for the preceding
                       year or the year in which the Change of Control occurs),
                       payable at the times such amounts would have been paid;
                       PROVIDED, HOWEVER, that if Executive so chooses, in his
                       sole discretion, such payment under this subparagraph
                       (f)(i) shall be made in a lump sum. In addition, the
                       Company shall reimburse Executive (net after taxes on the
                       receipt of such reimbursement) for any premiums paid by
                       Executive for health insurance provided to Executive (for
                       Executive and his dependents) by the Company subsequent
                       to the end of the Employment Period pursuant to the
                       requirements of COBRA as in effect on the date of this
                       Agreement.

                  (ii) Notwithstanding any provision of this Agreement to the 
                       contrary, if any amount or benefit to be paid or provided
                       under this Agreement or otherwise pursuant to or by
                       reason of any other agreement, policy, plan, program or
                       arrangement, including without limitation any bonus,
                       stock option, performance share, performance unit, stock
                       appreciation right or similar right, or the lapse or
                       termination of any restriction on or the vesting or

<PAGE>   9

                    exercisability of any of the foregoing would be an "Excess
                    Parachute Payment," within the meaning of Section 280G of
                    the Code, or any successor provision thereto, but for the
                    application of this sentence, then the payments and benefits
                    to be paid or provided under this Agreement shall be reduced
                    to the minimum extent necessary (but in no event to less
                    than zero) so that no portion of any such payment or
                    benefit, as so reduced, constitutes an Excess Parachute
                    Payment; provided, however, that the foregoing reduction
                    shall be made only if and to the extent that such reduction
                    would result in an increase in the aggregate payment and
                    benefits to be provided to Executive, determined on an
                    after-tax basis (taking into account the excise tax imposed
                    pursuant to Section 4999 of the Code, or any successor
                    provision thereto, any tax imposed by any comparable
                    provision of state law, and any applicable federal, state
                    and local income taxes). The determination of whether any
                    reduction in such payments or benefits to be provided under
                    this Agreement is required pursuant to the preceding
                    sentence shall be made at the expense of the Company, if
                    requested by the Executive or the Company, by the Company's
                    independent accountants. The fact that the Executive's right
                    to payments or benefits may be reduced by reason of the
                    limitations contained in this paragraph 6(f) shall not of
                    itself limit or otherwise affect any other rights of the
                    Executive other than pursuant to this Agreement. In the
                    event that any payment or benefit intended to be provided
                    under this Agreement is required to be reduced pursuant to
                    this paragraph 6(f), the Executive shall be entitled to
                    designate the payments and/or benefits to be so reduced in
                    order to give effect to this paragraph 6(f). The Company
                    shall provide the Executive with all information reasonably
                    requested by the Executive to permit the Executive to make
                    such designation. In the event that the Executive fails to
                    make such designation within 10 business days of the Date of
                    Termination, the Company may effect such reduction in any
                    manner it deems appropriate.

     (g) Without limiting the rights of the Executive at law or in equity, if
the Company fails to make any payment or provide any benefit required to be made
or provided hereunder on a timely basis, the Company will pay interest on the
amount or value thereof at an annualized rate of interest equal to the so-called
composite "prime rate" as quoted from time to time during the relevant period in
the Midwest Edition of THE WALL STREET JOURNAL. Such interest will be payable as
it accrues on demand. Any change in such prime rate will be effective on and as
of the date of such change.

     (h) Executive shall not be required to mitigate the amount of any payment
or benefit provided for in this Agreement by seeking other employment or
otherwise.

     7. CONFIDENTIAL INFORMATION. Executive acknowledges that the information,
observations and data obtained by him while employed by the Company pursuant to
this Agreement, as well as those obtained by him while employed by the Company
or any of its subsidiaries or affiliates or any predecessor thereof prior to the
date of this Agreement, concerning the business or affairs of the Company or any
of its subsidiaries or affiliates or any predecessor thereof (unless and

<PAGE>   10

except to the extent the foregoing become generally known to and available for
use by the public other than as a result of Executive's acts or omissions to
act, "CONFIDENTIAL INFORMATION") are the property of the Company or such
subsidiary or affiliate. Therefore, Executive agrees that during the Employment
Period and for two years thereafter he shall not disclose any Confidential
Information without the prior written consent of the Chief Executive Officer of
the Company unless and except to the extent that such disclosure is (i) made in
the ordinary course of Executive's performance of his duties under this
Agreement or (ii) required by any subpoena or other legal process (in which
event Executive will give the Company prompt notice of such subpoena or other
legal process in order to permit the Company to seek appropriate protective
orders), and that he shall not use any Confidential Information for his own
account without the prior written consent of the Chief Executive Officer of the
Company. Executive shall deliver to the Company at the termination of the
Employment Period, or at any other time the Company may reasonably request, all
memoranda, notes, plans, records, reports, computer tapes and software and other
documents and data (and copies thereof) relating to the Confidential
Information, or to the work product or the business of the Company or any of its
subsidiaries or affiliates which he may then possess or have under his control.

     8. NON-COMPETE, NON-SOLICITATION.

     (a) Executive acknowledges that in the course of his employment with the
Company pursuant to this Agreement he will become familiar, and during the
course of his employment by the Company or any of its subsidiaries or affiliates
or any predecessor thereof prior to the date of this Agreement he has become
familiar, with trade secrets and customer lists of and other confidential
information concerning the Company and its subsidiaries and affiliates and
predecessors thereof and that his services have been and will be of special,
unique and extraordinary value to the Company.

     (b) Executive agrees that during the Employment Period and for a period of
two years after termination of his employment with the Company, he shall not in
any manner, directly or indirectly, through any person, firm or corporation,
alone or as a member of a partnership or as an officer, director, shareholder,
investor or employee of or in any other corporation or enterprise or otherwise,
engage in or be engaged in, or assist any other person, firm, corporation or
enterprise in engaging or being engaged in, any business then actively being
conducted by the Company or any of its subsidiaries or affiliates.

     (c) Executive further agrees that during the Employment Period and for a
period of two years after termination of his employment with the Company, he
shall not in any manner, directly or indirectly, induce or attempt to induce any
employee of the Company or of any of its subsidiaries or affiliates to quit or
abandon his employ.

     (d) Nothing in this paragraph 8 shall prohibit Executive from being: (i) a
shareholder in a mutual fund or a diversified investment company or (ii) a
passive owner of not more than 5% of the outstanding equity securities of any
class of a corporation or other entity which is publicly traded, so long as
Executive has no active participation in the business of such corporation or
other entity.

<PAGE>   11

     (e) If, at the time of enforcement of this paragraph, a court holds that
the restrictions stated herein are unreasonable under circumstances then
existing, the parties hereto agree that the maximum period, scope or
geographical area reasonable under such circumstances shall be substituted for
the stated period, scope or area and that the court shall be allowed to revise
the restrictions contained herein to cover the maximum period, scope and area
permitted by law.

     9. ENFORCEMENT. Because Executive's services are unique and because
Executive has access to Confidential Information and work product, the parties
hereto agree that the Company would be damaged irreparably in the event any of
the provisions of paragraph 8 hereof were not performed in accordance with their
specific terms or were otherwise breached and that money damages would be an
inadequate remedy for any such non-performance or breach. Therefore, the Company
or its successors or assigns shall be entitled, in addition to other rights and
remedies existing in their favor, to an injunction or injunctions to prevent any
breach or threatened breach of any of such provisions and to enforce such
provisions specifically (without posting a bond or other security).

     10. EXECUTIVE REPRESENTATIONS. Executive represents and warrants to the
Company that (i) the execution, delivery and performance of this Agreement by
Executive does not and will not conflict with, breach, violate or cause a
default under any contract, agreement, instrument, order, judgment or decree to
which Executive is a party or by which he is bound, (ii) Executive is not a
party to or bound by any employment agreement, noncompete agreement or
confidentiality agreement with any other person or entity, and (iii) upon the
execution and delivery of this Agreement by the Company, this Agreement shall be
the valid and binding obligation of Executive, enforceable in accordance with
its terms.

     11. SURVIVAL. Subject to any limits on applicability contained therein,
paragraphs 7 and 8 hereof shall survive and continue in full force in accordance
with their terms notwithstanding any termination of the Employment Period.

     12. NOTICES. Any notice provided for in this Agreement shall be in writing
and shall be either personally delivered, sent by reputable overnight carrier or
mailed by first class mail, return receipt requested, to the recipient at the
address below indicated:

     Chief Executive Officer
     Penton Media, Inc.
     1100 Superior Avenue
     Cleveland, OH 44114

or such other address or to the attention of such other person as the recipient
party shall have specified by prior written notice to the sending party. Any
notice under this Agreement will be deemed to have been given when so delivered,
sent or mailed.

     13. SEVERABILITY. Whenever possible, each provision of this Agreement shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

     14. PAYMENT OF CERTAIN COSTS AND EXPENSES.

     (a) PREVAILING PARTY'S LITIGATION EXPENSES. In the event of litigation
between the Company and Executive related to this Agreement, the non-prevailing
party shall reimburse the prevailing party for any costs and expenses (including
without limitation attorneys' fees) reasonably incurred by the prevailing party
in connection therewith.

     (b) CHANGE OF CONTROL OF THE COMPANY. Without limiting the generality of
(a) above, in the event that there is a Change of Control of the Company, if it
should appear to Executive that the Company has failed to comply with any of its
obligations under this Agreement or in the event that the Company or any other
person takes or threatens to take any action to declare this Agreement void or
unenforceable, or institutes any litigation or other action or proceeding
designed to deny, or to recover from, Executive the benefits provided or
intended to be provided to Executive hereunder, the Company irrevocably
authorizes Executive from time to time to retain counsel of Executive's choice,
at the expense of the Company as hereafter provided, to advise and represent
Executive in connection with any such interpretation, enforcement or defense,
including without limitation the initiation or defense of any litigation or
other legal action, whether by or against the Company or any Director, officer,
shareholder or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to Executive's
entering into an attorney-client relationship with such counsel, and in that
connection the Company and Executive agree that a confidential relationship will
exist between Executive and such counsel. Without respect to whether Executive
prevails, in whole or in part, in connection with any of the foregoing, the
Company will pay and be solely financially responsible for any and all
attorneys' and related fees and expenses incurred by Executive in connection
with any of the foregoing.

     (c) SOURCE OF PAYMENTS. Except as otherwise specified herein, in the event
a Change of Control occurs, any payments to Executive pursuant to this Agreement
and the performance of the Company's obligations hereunder shall be secured by
amounts deposited or to be deposited in a trust established by the Company for
the benefit of Executive (and, at the Company's option, for the benefit of other
executives of the Company who are entitled to payments similar to those provided
in this Agreement) (the "Trust"). The Company shall transfer to such Trust
assets from which all or a portion of the payments provided under this Agreement
are to be paid,

<PAGE>   13

provided that such assets of the Trust shall at all times be subject to the
claims of general unsecured creditors of the Company and that neither Executive
nor any other person entitled to payments through the Trust shall at any time
have a prior claim to such assets. Any payments to Executive under this
Agreement that are not paid through the Trust shall be paid from the Company's
general assets, and Executive shall have the status of a general unsecured
creditor with respect to the Company's obligations to make payments under this
Agreement.

     15. COMPLETE AGREEMENT. This Agreement embodies the complete agreement and
understanding between the parties with respect to the subject matter hereof and
effective as of its date supersedes and preempts any prior understandings,
agreements or representations by or between the parties, written or oral, which
may have related to the subject matter hereof in any way.

     16. COUNTERPARTS. This Agreement may be executed in separate counterparts,
each of which shall be deemed to be an original and both of which taken together
shall constitute one and the same agreement.

     17. SUCCESSORS AND ASSIGNS. This Agreement shall bind and inure to the
benefit of and be enforceable by Executive, the Company and their respective
heirs, executors, personal representatives, successors and assigns, except that
neither party may assign any of his or its rights or delegate any of his or its
obligations hereunder without the prior written consent of the other party.
Executive hereby consents to the assignment by the Company of all of its rights
and obligations hereunder to any successor to the Company by merger or
consolidation or purchase of all or substantially all of the Company's assets,
provided such transferee or successor assumes the liabilities of the Company
hereunder.

     18. CHOICE OF LAW. This Agreement shall be governed by the internal law,
and not the laws of conflicts, of the State of Ohio.

     19. AMENDMENT AND WAIVER. The provisions of this Agreement may be amended
or waived only with the prior written consent of the Company and Executive, and
no course of conduct or failure or delay in enforcing the provisions of this
Agreement shall affect the validity, binding effect or enforceability of this
Agreement.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date written below.
