ITEM 1.  BUSINESS

GENERAL

     Penton Media is a diversified business-to-business ("b-to-b") media
company. We provide media products that deliver proprietary business information
to owners, operators, managers and professionals in the industries we serve.
Through these products, we offer industry suppliers multiple ways to reach their
customers and prospects as part of their sales and marketing efforts. We publish
43 specialized trade magazines, produce 35 trade shows and conferences, and
provide Web sites, electronic newsletters, Web conferences and other Web-based
media products.

     In June 2004, the Company appointed David B. Nussbaum as Chief Executive
Officer ("CEO"). Mr. Nussbaum is now Penton's chief operating decision maker.
After reviewing the Company's operations, Mr. Nussbaum and the executive team
implemented a change in the Company's reportable segments effective in the third
quarter of 2004 to conform with the way the Company's businesses are now
assessed and managed. The Company is structured along segment and industry lines
rather than by product lines. This enables us to promote our related group of
products, including publications, trade shows and conferences, and online media
products, to our customers. As a result of this change in reportable segments,
all prior periods were recast to conform with the new segment format. Our five
principal segments and the industries they serve are as follows:

<Table>
           <S>                                      <C>

           INDUSTRY                                 TECHNOLOGY
           Manufacturing                            Business Technology

           INTERNATIONAL                            Hospitality
           United Kingdom
</Table>

     Since our founding in 1892, we have grown from an industrial trade magazine
publishing company into an integrated b-to-b media company serving a wide range
of industrial, technology and retail markets. We became an independent company,
incorporated in the State of Delaware, as a result of our spinoff from Pittway
Corporation in August 1998.

     Our principal executive offices are located at The Penton Media Building,
1300 East Ninth Street, Cleveland, Ohio 44114, telephone 216-696-7000.

     We maintain a Web site at http://www.penton.com. The information contained
on our Web site is not incorporated by reference in this report, and you should
not consider it a part of this report. Our Annual Report on Form 10-K, Quarterly
Reports on Form 10-Q, Current Reports on Form 8-K, and any amendments to those
reports are available free of charge on our Web site as soon as reasonably
practicable after they are filed, or furnished to, the Securities and Exchange
Commission.

     Unless otherwise noted herein, disclosures in this Annual Report on Form
10-K relate only to our continuing operations. Our discontinued operations
consist of Penton Media Australia Pty, Limited ("PM Australia"), which was sold
in December 2002, and Professional Trade Shows ("PTS"), which was sold in
January 2003.

     Unless the context otherwise requires, the terms "we," "our," "us,"
"Company," and "Penton" as used herein refer to Penton Media, Inc. and its
subsidiaries.

RECENT DEVELOPMENTS

RESTATEMENT OF FINANCIAL STATEMENTS

     On March 24, 2005, the Company's management concluded that the Company's
previously issued consolidated financial statements should be restated to
increase income tax expense to correct the computation of our valuation
allowance for deferred tax assets. Management reached this conclusion following
a comprehensive review of the Company's deferred tax assets and deferred tax
liabilities. The Company determined that certain deferred tax liabilities had
been incorrectly offset against its deferred tax assets. Under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes," taxable
temporary differences related to indefinite-lived intangible assets or
tax-deductible goodwill (for which reversal cannot be anticipated) should not be
offset against deductible temporary differences for other indefinite-lived
intangible assets or tax-deductible goodwill when scheduling reversals of
temporary differences.

     The Company evaluated the materiality of the correction on its consolidated
financial statements using the guidelines of Staff Accounting Bulletin 99,
"Materiality" ("SAB 99") and concluded that the cumulative effects of the
corrections were material to its annual consolidated financial statements for
2004, 2003 and 2002 and the related quarterly consolidated financial statements
for such periods. As a result, the Company concluded that it will restate its
previously issued consolidated financial statements to recognize the impact of
the correction, as well as other accounting adjustments that were deemed in
earlier periods to be immaterial.

     These financial statements have been restated to reflect adjustments to the
Company's previously reported financial information on Form 10-K for the years
ended December 31, 2003 and 2002. The Company's 2004 and 2003 quarterly
financial information also has been restated to reflect adjustments to the
Company's previously reported financial information on Form 10-Q for the
quarters ended March 31, 2004, June 30, 2004 and September 30, 2004. As a result
of the restatement, the Company identified adjustments through the filing date
of this Form 10-K that were required to be recorded which increased previously
reported stockholders' deficit at December 31, 2003 and September 30, 2004 by
$15.4 million and $17.1 million (unaudited), respectively. For additional
information on the restatement, see Note 2 -- Restatement, in the notes to
consolidated financial statements included herein.

     The Company will restate the quarterly periods ended March 31, 2004, June
30, 2004, and September 30, 2004 on Forms 10-Q/A to be filed as expeditiously as
possible.

SENIOR SUBORDINATED NOTES REPURCHASE

     In February 2005, the Company repurchased $5.5 million par value of its
10 3/8% senior subordinated notes ("Subordinated Notes") for a total of $3.9
million, including $0.1 million of accrued interest, using excess cash on hand.
These notes were purchased in the open market and were trading at 69% of their
par value at the time of purchase. The repurchase resulted in a gain of
approximately $1.6 million, which will be recognized in the first quarter of
2005.

LOAN AND SECURITY AGREEMENT

     On March 30, 2005, the Company received an extension until May 15, 2005 to
deliver its annual audited financial statements to its Lender Group. The terms
of our Loan and Security Agreement require us to provide annual audited
financial statements within 90 days of the end of our fiscal year.

     On April 1, 2005, the Company borrowed $6.0 million under the Company's
Loan and Security Agreement. The proceeds were used to pay the interest due on
April 1 under the Company's 11 7/8% senior secured notes ("Secured Notes").

SALE OF PROPERTIES

     In December 2004, the Company completed the sale of 70% of its interest in
Penton Media Germany ("PM Germany"), a consolidated subsidiary, to Neue Medien
Ulm Holdings GmbH ("Neue Medien") for $0.8 million in cash, resulting in a loss
of approximately $0.9 million classified in loss (gain) on sale of

                                        4
<PAGE>

properties, on the accompanying consolidated statements of operations. The
Company retains a 15% interest in PM Germany, which includes a call/put option.
The Company accounts for its investment using the cost method, as the Company
does not exercise significant influence.

FORWARD-LOOKING INFORMATION (SAFE HARBOR STATEMENT)

     This Annual Report on Form 10-K contains statements relating to Penton
Media, Inc. (including its future results and business trends) that are
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended, and are subject to the "safe harbor" created by those sections.
Although Penton believes that the expectations reflected in such forward-looking
statements are based upon reasonable assumptions, it can give no assurance that
its expectations will be achieved. Actual results or events may differ
materially from those projected as a result of certain risks and uncertainties.
These risks and uncertainties include, but are not limited to, those set forth
herein under the heading "Risk Factors." For this purpose, any statements
contained herein that are not statements of historical fact may be deemed to be
forward-looking statements. Without limiting the foregoing, the words
"believes," "anticipates," "plans," "expects," "seeks," "estimates" and similar
expressions are intended to identify forward-looking statements. These
forward-looking statements are made only as of the date hereof, and we undertake
no obligation to update or revise any of them, whether as a result of new
information, future events or otherwise.

OUR INDUSTRY

     The b-to-b media industry provides information in various formats to
targeted business and professional audiences. B-to-b media include print
products such as magazines and newsletters; in-person media such as trade shows
and conferences; and online media, such as Web sites, Web conferences,
electronic newsletters, and electronic books.

     Through b-to-b media, marketers can reach targeted business and
professional audiences whose responsibilities include the buying or specifying
of products and services for their business organizations. Marketing
opportunities include advertising in specialized business magazines; exhibiting
at or sponsoring trade shows and conferences; sponsorship of digital media and
highly customized media products; and the strategic use of products related to
core media products, such as direct marketing mailing and e-mail lists, article
reprints and electronic reuse of content; and exclusive market intelligence and
data.

     The b-to-b media industry suffered significant declines in 2001 and 2002 as
the weak economy, disappointing corporate profits and the lingering effects of
geopolitical events pressured many companies to reduce costs, including
marketing spending.

     As the economy strengthened in 2003 and 2004 and companies gained
confidence in their business results and re-engaged in marketing investment,
b-to-b media experienced growth, albeit modest. Advertising pages in U.S. b-to-b
magazines grew 1.4%, and advertising spending in b-to-b magazines grew by 3.8%
in 2004, according to the Business Information Network ("BIN"). Net square
footage of exhibit space at trade shows held in North America grew by 1.5%, the
number of exhibiting companies expanded 1.6%, and attendance grew by 2.7%,
according to Tradeshow Week magazine. Many b-to-b media companies also
experienced significant growth in their online media product lines, as marketers
continued a trend of allocating increased spending to a wide range of Web-based
opportunities.

     U.S. spending in b-to-b magazines and trade shows is projected to grow at a
compounded annual growth rate of 4.0% in the period 2003 to 2008, according to
the July 2004 Veronis Suhler Stevenson Media Merchant Bank's Communications
Industry Forecast & Report.

THE PENTON BUSINESS MODEL

     Penton's strategic goal is to be the leading provider of integrated media
and marketing solutions in the target markets we serve.

                                        5
<PAGE>

     Our business is organized along segment and industry lines, rather than
product lines. This business model allows our staff to develop deeper market
knowledge and experience that benefits our customers through our ability to
develop and produce the most relevant and timely information products, and our
ability to provide marketing counsel and services to marketers that reflect the
most current market conditions, trends and opportunities.

     Operating in a market-focused manner also allows us to cross-promote our
related groups of publications, trade shows and conferences, online media, and
custom media solutions to our customers. This enables our customers to utilize
multiple complimentary channels for delivering their marketing message to their
best sales prospects and provides us with the opportunity to capture a larger
share of our customers' total marketing expenditure.

IN PRINT: PUBLICATIONS

     We publish specialized trade magazines in the United States. Of our 33
magazines that are audited by a third-party service, 25 magazines, or 76%, hold
the number-one or number-two market share position in their target markets,
based on the number of advertising pages. Our publications are recognized for
the quality of their editorial content; since 1990, our magazines have won more
than 880 editorial awards.

     We publish 43 trade magazines that are published six times or more per
year. These titles have a combined circulation of about 3.0 million subscribers.
Our magazines generate revenues primarily from the sale of advertising space and
are primarily distributed through controlled circulation free of charge to
qualified subscribers in our target industries. Subscribers to
controlled-circulation publications qualify to receive our trade magazines by
verifying, among other things, their responsibility for specific job functions,
including purchasing authority. We survey our magazine subscribers annually to
verify their continuing qualification.

     BPA Worldwide, an independent auditor of magazine circulation, audits
circulation information for the majority of our publications each year. 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 reaching customers and
prospects in multiple but related markets.

     In addition, each of our publications has its own editorial staff. 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. Seventeen
of our publications have served their industries for more than 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 their respective 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 markets.

     We also publish print and online industry directories and buyers' guides,
which are respected sources of purchasing information for professionals in the
markets we serve.

IN PERSON: TRADE SHOWS, CONFERENCES AND ROADSHOWS

     We produce 35 trade shows and conferences, which attract attendees with
purchasing and specifying responsibility.

                                        6
<PAGE>

     Attendees at our trade shows and conferences are professionals and managers
in the industries we serve. Our trade shows include extensive conference
programs, which provide a forum for the exchange and dissemination of
information relevant to attendees' professional roles and responsibilities.

     Trade show exhibitors pay a fixed price per square foot for booth space. In
addition, we receive revenues from attendee fees and from exhibitor sponsorships
of promotional media.

     Our conferences are supported by either attendee registration fees or
marketer sponsorship fees, or a combination of both. The high quality and
unbiased nature of our conference content attract professional attendees. We are
able to cost-effectively promote to attendees by utilizing related media
products serving the same end-user audience. For example, potential attendees
are the readers of our magazines and the users of our Web sites and electronic
newsletters.

     We also produce roadshow conferences, which are typically sponsored by a
single or small group of sponsors and address special topics of interest to
business attendees. The roadshow conferences take place in multiple markets as
determined by concentration of local attendees and the marketing objectives of
sponsors. As a turnkey organizer, Penton typically manages content development,
recruitment of presenters, attendee marketing and site logistics. While
sponsorship fees represent the greatest source of revenues for roadshows, we
sometimes also generate revenues from attendees.

ONLINE: WEB SITES AND ELECTRONIC NEWSLETTERS

     We currently maintain 41 Web sites serving numerous markets. Our online
portfolio also includes electronic newsletters; Web conferences; sponsored
topic-specific microsites; and electronic books. These products provide timely
and focused information to highly targeted professionals, and typically are
sponsored by advertisers interested in delivering marketing information to these
professionals because of their product/service purchasing or specifying
responsibilities. We believe we have a competitive advantage in the online
business because of our established customer relationships in the markets we
serve, the industry and product development expertise of our staff, and the
opportunities we have to promote our online media to targeted audiences through
our magazines and trade shows.

CUSTOM MEDIA

     Providing integrated media and marketing solutions to our customers also
involves producing customized media products that address specific marketing
communications objectives. We produce a wide range of customer-sponsored
communications, such as sponsored magazines, newsletters, catalogs, education
and training materials, electronic books and Web-based conferences.

     We also sell a variety of ancillary products that our customers use in
their direct marketing and promotional efforts. These include article reprints
and rights for electronic re-use of our editorial content, and rentals of our
magazine subscriber and event attendee databases.

OUR BUSINESS SEGMENTS

     Our five segments derive their revenues from in-print publications,
in-person trade shows and conferences, and online media to customers in the
industries we serve. These segment results are regularly reviewed by the
Company's executive management team to determine how resources will be allocated
to the segments and in assessing segment performance.

     For information about the revenues from external customers, adjusted
segment EBITDA and total assets of each of our business segments, see Note
18 -- Segment Information, in the notes to consolidated financial statements
included herein. In addition, Item 7 -- Management's Discussion and Analysis of
Financial Condition and Results of Operations, provides a description of segment
results.

online media products is geared to customers in the manufacturing,
design/engineering, mechanical systems/construction, and government/compliance
industries. Our Industry segment generated 35.2%, 36.5% and 35.0% of our total
revenues in 2004, 2003 and 2002, respectively. The percentages of the Industry

MANUFACTURING:

     Our manufacturing portfolio represented approximately 10.0% of our revenues
in 2004. This portfolio targets executives in manufacturing organizations,
managers of industrial facilities, material handling engineers, third-party
logistics providers, and management personnel in the machine tool and metals
industries. Many of our products in this portfolio have a long history and are
leaders in the industry. They include the following:

     - IndustryWeek, first published in 1882, brings together senior
       manufacturing executives to explore business issues, strategies, trends
       and technologies that can help them succeed in today's "better, faster,
       cheaper" global economy. IndustryWeek focuses on providing well-informed
       ideas and best practices presented from an authoritative point-of-view.

     - American Machinist, first published in 1877, focuses on the metalworking
       marketplace, which consists of industries primarily engaged in
       manufacturing durable goods and other metal products.

     - Material Handling Management magazine reaches subscribers responsible for
       material handling functions in manufacturing, warehousing and
       distribution. Editorial content focuses on material handling
       applications, technology and management strategies for increasing
       productivity, cutting operating costs, improving safety, supporting
       effective planning, and facilitating product/information flow.

     - Logistics Today serves the transportation, warehousing and distribution,
       technology, and global business markets. Its content focuses on what is
       new, what others are doing, and what trends will impact future work.

     - New Equipment Digest, first published in 1936, presents concise
       descriptions and photos of new and/or improved industrial products,

DIVESTITURES

     In December 2004, the Company completed the sale of 70% of its interest in
PM Germany, a consolidated subsidiary, to Neue Medien Ulm Holdings GmbH ("Neue
Medien") for $0.8 million in cash. PM Germany was part of our International
segment. The sale did not qualify as discontinued operations under SFAS No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144").
Consequently, the related loss on sale of $0.9 million is included in loss on
sale of properties on the accompanying consolidated statements of operations. At
December 31, 2004, the Company retains a 15% interest in PM Germany, which
includes a call/put option. The Company accounts for its investment using the
cost method, as the Company does not exercise significant influence.

     In January 2003, the Company completed the sale of the assets of its PTS
group, which was part of our Industry segment, to Cygnus Business Media, Inc.
for total consideration of approximately $3.2 million. The cash received from
the sale was used to pay down the Company's outstanding credit facility. A gain
of approximately $1.4 million on the sale was recorded in the first quarter of
2003. The results of PTS are

facility. The related loss on the sale of approximately $0.6 million is included

The aggregate consideration for these properties was approximately $0.9 million.
The cash received from these sales was used to pay down the Company's
outstanding credit facility. The sale of the properties resulted in a loss of
approximately $0.9 million and is included in operations as loss on sale of
properties in the accompanying consolidated statements of operations as these
properties did not qualify for discontinued operations treatment.

COMPETITION

     We experience intense competition for our products and services. We compete
with several much larger international companies that operate in many markets
and have broad product offerings in both publishing and trade shows and
conferences. We compete for readers and advertisers in the publishing
marketplace, which is fragmented. According to industry sources, in March 2005,
there were about 1,500 publishing companies and more than 5,200 trade magazine
titles.

     Our publications generally compete on the basis of:

        - editorial quality and integrity;

        - quantity and quality of circulation;

        - the strength of complementary products serving the same niche;

        - the effectiveness of sales and customer service; and

        - advertising rates.

     In certain markets we serve with our trade shows and conferences, we
compete for venues, exhibitors, sponsorships and show attendees.

        - the availability of attractive venues and dates;

        - the quality and integrity of educational offerings;

        - the ability to provide events that meet the needs of particular market
          segments;

        - the ability to attract qualified attendees; and

          and attractive marketing and sponsorship opportunities.

<PAGE>

     As online media has gained favor for both information delivery and for
marketing purposes, there has been a major influx of new product offerings by
b-to-b media companies and other information providers who represent added
competition.

     Our online media products generally compete on the basis of:

        - quality and uniqueness of information content;

        - quality and speed of sales lead generation;

        - technical quality and the related ease of use for the end user;

        - product development speed; and

        - advertising and sponsorship rates.

OUR BUSINESS STRATEGY

     Over the past four years, Penton has responded aggressively to the severe
downturn in our financial performance. We substantially reduced the Company's
fixed costs by reducing our net headcount by 56.5% in the period 2001 to 2004,
including 71 positions in 2004; freezing our pension plan and introducing a
defined contribution plan; reducing capital spending; outsourcing certain
corporate and division functions; renegotiating key vendor contracts; and
implementing process improvements.

     Our strategy for restoring stockholder value is now directed toward
expanding revenues so that the operating leverage that these cost savings has
created will result in improved cash flows and return the Company to a positive
net cash flow position.

     The key elements of our strategy are to:

        - Provide each of our customer markets with a full range of media across
          all information delivery channels, including print, in-person and
          online media, thereby capturing a significant portion of available
          marketing expenditures;

        - Leverage our customers' desire to utilize online media to reach their
          marketing objectives by ensuring we offer a robust portfolio of
          digital media offerings, including traditional Web site advertising;
          search engine advertising; Web-based conferencing; e-newsletters; and
          e-books;

        - Extend the market equity of our long-established, respected print
          media brands by launching new products and services in emerging,
          related markets;

        - Provide valued services that build community and meaningful
          buyer-seller connections in the markets we serve, thereby
          differentiating Penton from its competitors;

        - Develop a corporate culture that thrives through open communication
          and effective cross-sharing of business ideas; and

        - Continue to seek cost efficiencies and business process improvements.

2002, respectively. In 2004, 2003 (as restated) and 2002, 81.9%, 81.0% and
74.9%, respectively, of these foreign revenues were generated by Penton Media
Europe Limited, a subsidiary of Penton located in the United Kingdom. See Note
18 -- Segment Information, in 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.

PRODUCTION AND DISTRIBUTION

     All of the Company's print products are printed and bound by independent
printers. We have a non-cancelable service contract through 2006 that provides
for the printing of a majority of our magazines. In 2005, we signed a new
printing agreement with our current service provider, which extends through
2011. If additional printing capacity is needed, we believe that additional
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, in any event, alternative sources are available. Paper costs
accounted for approximately 8.0%, 7.8% and 8.4% of our total editorial,
production and circulation costs for the years ended December 31, 2004, 2003 and
2002, respectively. Paper prices are affected by a variety of factors, including
demand, capacity, pulp supply, and general economic conditions.

     Substantially all of our publications are delivered by the United States
Postal Service within the continental United States. Consequently, postage costs
are subject to postage rate changes. Postage costs represent a significant
expense, accounting for approximately 13.3%, 14.5% and 14.2% of our total
editorial, production and circulation costs for the years ended December 31,
2004, 2003 and 2002, respectively. Most of the Company's magazines are packaged
and delivered to the United States Postal Service directly by the printer.
Postage rates increased on June 30, 2002. In April 2003, President Bush signed
legislation that will hold postal rates stable until at least 2006.

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 licenses 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 any 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

     We may experience seasonal fluctuations as trade shows and conferences held
in one quarter in the current year may be held in a different quarter in future
years.

EMPLOYEES

     On December 31, 2004, we employed 779 people, primarily in the United
States. None of our employees are represented by a labor union, and we consider
relations with our employees to be good.

RISK FACTORS

     The following are factors that may affect our actual operating results and
could cause results to differ materially from those in any forward-looking
statements. In addition to the other information contained in this document, you
should carefully consider the following risk factors.

We are incurring substantial operating losses, we anticipate additional future
losses and we must increase our revenues to become profitable.

     We incurred net losses of $67.2 million, $93.1 million and $296.5 million
in 2004, 2003 (as restated) and 2002 (as restated), respectively. We face an
environment of uncertainty, and visibility for the Company's

                                        16
<PAGE>

business, particularly advertising sales, remains limited. We expect that we
will continue to incur operating losses in the near term.

     In order to return to profitability, we must achieve substantial revenue
growth. Revenue growth will depend on a recovery in marketing spending in
traditional b-to-b media along with continued growth from new online media
offerings. Although we have implemented a number of expense reduction and
restructuring initiatives to more closely align our cost structure with the
current business environment, expense reductions alone, without revenue growth,
will not return us to profitability. We cannot assure you as to whether or when
we will return to profitability or whether we will be able to sustain such
profitability, if achieved.

We depend on advertising revenues, which decrease during economic downturns and
fluctuate from period to period.

     For the years ended December 31, 2004, 2003 (as restated), and 2002, about
58.6%, 62.0% and 59.7%, respectively, of our revenues came from advertising in
our publications. Our advertising revenues fluctuate with general economic
cycles, and any material decline in these revenues could have a material adverse
effect on our business, results of operations and financial condition.
Historically, advertising revenues have increased during economic recoveries and
decreased during both general economic downturns and regional economic
recessions. In a general economic downturn or a recession, advertisers reduce
their advertising budgets, intensify their attempts to negotiate lower
advertising rates and pay outstanding invoices more slowly. We have experienced
some of these effects in 2002, 2003 and 2004. Our advertising revenues decreased
by 9.0% from 2002 to 2003 and by 2.4% between 2003 and 2004. If the anticipated
recovery in marketing spending in traditional b-to-b media does not take place,
or is significantly delayed, our results of operations may be adversely
affected.

We have a significant amount of debt.

     At December 31, 2004, we had total indebtedness of approximately $329.1
million, net of approximately $3.0 million of original-issue discount on our
Subordinated Notes and approximately $0.5 million of original-issue discount on
our Secured Notes. Subject to restrictions in our debt instruments, we had the
ability to incur additional indebtedness of approximately $39.7 million under
our credit facility at December 31, 2004.

     The level of our indebtedness could have important consequences, including:

        - Limiting cash flow available for general corporate purposes, including
          capital expenditures, because a substantial portion of our cash flow
          from operations must be dedicated to servicing our debt;

        - Limiting our ability to obtain additional debt financing in the future
          for working capital, capital expenditures or acquisitions;

        - Making us more vulnerable in the event of a further downturn in
          general economic conditions or in our business; and

        - Limiting our flexibility in reacting to competitive and other changes
          in our industry.

     Our current debt levels have subjected us to the risks described above. If
new debt is added to our current debt levels, these risks could intensify.

We may not be able to service our debt.

     Our ability to pay or to refinance our indebtedness will depend upon our
future operating performance, which will be affected by general economic,
financial, competitive, business, and other factors beyond our control.

     We cannot assure you that our business will generate sufficient cash flow
from operations, that currently anticipated revenues and cost-saving efforts
will be realized on schedule or at all, or that future borrowings will be
available to us under our credit facility or otherwise in amounts sufficient to
enable us to service our debt

                                        17
<PAGE>

obligations, to pay our indebtedness at maturity or otherwise, or to fund our
other liquidity needs. If we are unable to meet our debt obligations or fund our
other liquidity needs, we may need to further restructure or refinance our
indebtedness, sell assets or seek additional equity capital. We cannot assure
you that we will be able to accomplish those actions on satisfactory terms, if
at all, which could cause us to default on our obligations and impair our
liquidity. Our ability to restructure or refinance will depend on the capital
markets and our financial condition at such time. Any refinancing of our debt
could be at higher interest rates and may require us to comply with more onerous
covenants, which could further restrict our business operations. In addition,
the terms of the convertible preferred stock and warrants to purchase common
stock, including the conversion price, dividend and liquidation preference
adjustment provisions, could result in substantial dilution to holders of our
common stock. The redemption price premiums, and board representation rights,
could negatively impact our ability to access the equity markets in the future.

     Because a significant portion of our operations are currently conducted
through our subsidiaries, our ability to pay our indebtedness is also dependent
on the cash flows of our subsidiaries and the distribution of those cash flows
to us, or upon loans or other payments of funds by our subsidiaries to us. The
ability of our subsidiaries to make distributions or other payments to us will
depend upon their operating results, applicable laws and any contractual
restrictions contained in the instruments governing their indebtedness. If money
generated by our subsidiaries is not available to us, our ability to repay our
indebtedness may be adversely affected.

The terms of our debt instruments and convertible preferred stock impose
financial and operating restrictions.

     The indentures governing our Subordinated Notes and our Secured Notes, our
loan and security agreement and our convertible preferred stock contain
restrictive covenants that limit our ability to engage in a variety of
transactions, including incurring or guaranteeing additional indebtedness,
making investments, creating liens on our assets, transferring or selling our
assets, paying dividends or engaging in certain mergers, acquisitions or
consolidations. The terms of our credit facility prohibit us from voluntarily
prepaying certain indebtedness.

     A breach of any of the covenants or other provisions in our debt
instruments could result in a default thereunder. Upon the occurrence of an
event of default under our debt instruments, the lenders could elect to declare
all amounts outstanding thereunder to be immediately due and payable and
terminate all commitments to extend further credit, which would adversely affect
our ability to fund our operations. An acceleration of amounts due under our
loan and security agreement would cause us to be in default under the indenture
governing our Subordinated Notes and our Secured Notes, resulting in the
acceleration of all outstanding amounts, and vice versa, given certain
thresholds. If we are unable to repay any accelerated amounts under our debt
instruments, the respective lenders/holders could proceed against the collateral
granted to them to secure that indebtedness. If the lenders/holders under our
debt instruments accelerate the repayment of borrowings, we cannot assure you
that we will have sufficient assets to repay all of our indebtedness.

We are controlled by our Series C preferred stockholders whose interests may
differ from the interests of the common stockholders.

     Effective at the annual meeting of stockholders on July 15, 2004, the
number of board members was reduced from 11 to 8. With this reduction, the
holders of the convertible preferred stock achieved and now constitute a
majority of the Company's Board of Directors. In addition, the Board of
Directors named Royce Yudkoff as its non-executive chairman. Mr. Yudkoff is a
co-founder of ABRY Partners, LLC and currently serves as its president and
managing partner. Affiliates of ABRY Partners, LLC own the majority of the
Company's convertible preferred stock.

     Circumstances may occur in which the interests of our Series C preferred
stockholders could be in conflict with the interests of our common stockholders.
As a result of their majority position, the Series C preferred stockholders have
the power to appoint new management as well as the power to approve acquisitions
or sales of our assets. If the Company is sold, we cannot assure the common
stockholders that

                                        18
<PAGE>

there will be enough proceeds from the sale to pay off all of our outstanding
debt, the outstanding amount due to the Series C preferred stockholders, and
have funds remaining for the common stockholders. If the Company would have been
sold as of March 31, 2005, the bondholders would be entitled to receive $330.3
million and the Series C preferred stockholders would be entitled to receive
$144.8 million before the common stockholders would receive anything for their
common shares.

If the U.S. and European economies worsen, the cost-saving efforts we
implemented may not be sufficient to achieve the benefits we expect.

     In 2002 and 2003, we experienced a significant decline in revenue, due
primarily to weak economic conditions, which were exacerbated by the threat of
additional terrorist attacks and the war with Iraq. Although revenues in 2004
increased by 3.2%, we cannot predict what the economy will do in the future. We
have taken a number of steps designed to improve our profits and margins despite
consistent-level or declining revenues. We have sold properties that were
underperforming; restructured a number of our businesses and support
departments; and reduced overhead infrastructure by consolidating and closing
several facilities, centralizing enterprise information technology services and
outsourcing certain corporate functions. As a result, we recorded special
charges to our income of $16.4 million in 2002, $5.9 million in 2003 (as
restated), and $6.2 million in 2004. If the U.S. and European economies worsen,
or if additional terrorist attacks occur, our revenues may decline. If revenues
decline beyond our expectations, the cost-saving efforts we implemented in 2002,
2003 and in 2004 will likely not achieve the benefits we expect. We may be
forced to take additional cost-saving steps that could result in additional
charges and otherwise have a material adverse affect on our business.

The profitability and success of our trade shows and conferences could be
adversely affected if we are unable to obtain desirable dates and locations.

     In 2004, about 24.2% of our revenues came from trade shows and conferences.
We compete for desirable dates and venues for our trade shows and conferences.
If this competition intensifies, we may be unable to schedule important
engagements. If we are unable to obtain desirable dates and venues for events,
the profitability and future success of these events could be adversely
affected. Although we generally reserve venues and dates more than one year in
advance, these reservations are not binding until we sign a contract with a
facility operator. These contracts generally hold venues and dates for only one
year. In addition, because trade shows and conferences are held on pre-scheduled
dates at specific locations, the success of a particular trade show or
conference depends upon events outside or our control, such as natural
catastrophes, labor strikes and transportation shutdowns.

A significant portion of our revenues and operating margin is generated from our
Natural Products Expo East and Natural Products Expo West trade shows. A major
decline in the performance of these shows would significantly reduce our
revenues and operating income.

     For the year ended December 31, 2004, our Natural Products Expo East and
Natural Products Expo West trade shows represented approximately 10.3% of our
total revenue and approximately 28.9% of operating margin. We expect that the
Natural Products Expo East and Natural Products Expo West trade shows will
continue to represent a significant portion of our overall revenue and operating
margin in the future. Therefore, a significant decline in the performance of one
or both of the Natural Products Expo East and Natural Products Expo West trade
shows could have a material adverse effect on our financial condition and
results of operations.

A terrorist attack or the outbreak of disease could have a significant effect on
our trade shows.

     The events of September 11, 2001 had a material adverse impact on the
Company. The occurrence of another terrorist attack could again have a material
adverse impact on the Company and its operations.

     In 2003, there was an outbreak of Severe Acute Respiratory Syndrome
("SARS"), which primarily had an adverse impact on the Company's Asia trade
show. If there were another outbreak of a disease (such as

                                        19
<PAGE>

SARS) that affected travel behavior, particularly in the U.S., it could have a
material adverse impact on the Company's trade show operations.

Our trade shows, conferences and publishing revenues vary due to the movement of
annual events or publication mailing dates and the timing of our customers'
product launches.

     Our trade shows, conferences and publishing revenues are seasonal, due
primarily to the timing of our large trade shows and conferences and the mailing
dates of our magazines and industry directories. Because event revenues are
recognized when a particular event is held, and publication revenues are
recognized in the month publications are mailed, we may also experience
fluctuations in quarterly revenues based on the movement of annual events or
mailing dates from one quarter to another. In 2004, about 25.6% of our total
revenues was generated during the first quarter, about 24.0% during the second,
about 24.8% during the third, and about 25.6% of our revenues was generated
during the fourth quarter.

     In addition, our trade show and conference revenues may fluctuate from
period to period based on the spending patterns of our customers. Many of our
large customers concentrate their trade show participation around major product
launches. Because we cannot always know or predict when our large customers
intend to launch new products, it is difficult to anticipate any related
fluctuations in our trade show and conference revenues.

We depend on key personnel and the loss of any of those employees could impair
our success.

     We benefit from the leadership and experience of our senior management team
and other key employees, and we depend on their continuing services in order to
successfully implement our business strategy. In addition, our success is
dependent on our ability to attract, train, retain and motivate high-quality
personnel. Although we have entered into employment agreements with David
Nussbaum, Preston L. Vice and Darrell Denny, they and other key personnel may
not remain in our employment. The loss of a number of key personnel could have a
material adverse effect on our business, results of operations and financial
condition. We do not maintain "key person" life insurance with respect to our
senior management team.

Competition may adversely affect our earnings and results of operations.

     We experience intense competition for our products and services. If we fail
to compete effectively, our earnings and results of operations could be
adversely affected. We compete for readers and advertisers in the publishing
marketplace and for trade show and conference venues, exhibitors, sponsorships
and show attendees. Because our industry is relatively easy to enter, we
anticipate that additional competitors, some of whom may have greater resources
than we do, may enter these markets and intensify competition.

Our overall operations may be adversely affected by risks associated with
international operations.

     We have operations outside the United States. 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;

     - difficulties in staffing and managing multinational operations;

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

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

     - reduced protection for intellectual property rights in some countries;

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

     - potentially adverse tax consequences.

                                        20
<PAGE>

New product launches or acquired products may reduce our earnings or generate
losses.

     Our future success will depend in part on our ability to continue offering
new products and services that gain market acceptance by addressing the needs of
specific audience groups within our targeted industries. Our efforts to
introduce new or to integrate acquired products may not be successful or
profitable. The process of internally researching, developing, launching,
gaining acceptance and establishing profitability for a new product, or
assimilating and marketing an acquired product, is both risky and costly.

     Costs related to the development of new products and services are expensed
as incurred and, accordingly, our profitability from year to year may be
adversely affected by the number, timing, and scope of new product launches.

The infringement or invalidation of our proprietary rights could have an adverse
effect on our business.

     We regard our copyrights and trademarks, including our Internet domain
names, service marks and similar intellectual property, as critical to our
success. We rely on copyright and trademark laws in the United States and other
jurisdictions and on confidentiality agreements with some of our employees and
others to protect our proprietary rights. If any of these rights were infringed
or invalidated, our business could be adversely affected. In addition, our
business activities could infringe or be alleged to infringe upon the
proprietary rights of others, who could assert infringement claims against us.
If we are forced to defend against any such claims, whether they are with or
without merit or are determined in our favor, then we may face costly
litigation, diversion of technical and management personnel, or product and
service delays. As a result of such a dispute, we may have to develop
non-infringing technology or enter into royalty or licensing agreements. Such
royalty or licensing agreements, if required, may be unavailable on terms
acceptable to us, or at all. If there is a successful claim of infringement
against us and we are unable to develop non-infringing technology or enter into
royalty or licensing agreements on a timely basis, our business could be
adversely affected.

     We seek to register our trademarks in the United States and elsewhere.
These registrations could be challenged by others or invalidated through
administrative process or litigation. In addition, our confidentiality
agreements with some of our employees or others may not provide adequate
protection of our proprietary rights in the event of unauthorized use or
disclosure of our proprietary information, or if our proprietary information
otherwise becomes known or is independently developed by competitors.

Reliance on principal vendors could adversely affect our business.

     We rely on our principal vendors and their ability or willingness to sell
products to us on favorable price and other terms. Many factors outside our
control may harm these relationships and the ability or willingness of these
vendors to sell these products to us on such terms. Currently, our principal
vendors are paper suppliers, the United States Postal Service and printing
suppliers. If any of our principal vendors discontinues or temporarily
terminates its services and we are unable to find adequate alternatives, we may
experience increased prices, interruptions and delays in services. These factors
could adversely affect our business.

Increases in paper or postage costs could cause our expenses to increase and may
adversely affect our business.

     Paper and postage are necessary expenses relating to our print products and
magazine distribution. In 2004, these expenses accounted for approximately 8.0%
and 13.3%, respectively, of our total editorial, production and circulation
costs. Significant increases in paper prices or in postage prices may have an
adverse effect on our business. We do not use forward contracts, and all of our
paper supply vendor arrangements provide for price adjustments to reflect
prevailing market prices. We use the United States Postal Service for domestic
distribution of substantially all of our magazines and marketing materials. If
we cannot pass significant increases in paper and postage costs through to our
customers, our financial condition and results of operations could be materially
adversely affected.

ITEM 3.  LEGAL PROCEEDINGS

     On November 3, 2003, a lawsuit was brought against the Company for an
unspecified amount by Allison & Associates, Inc. under the Telephone Consumer
Protection Act ("TCPA") which prohibits the transmission of unsolicited fax
advertisements. The lawsuit is a punitive class action that seeks to represent a
class of plaintiffs comprised of all individuals and entities who, during the
period November 3, 1999, through the present, received one or more facsimiles
sent by or on behalf of the Company advertising the commercial availability of
its products or services and who did not give their prior expressed permission
or invitation to receive such faxes. The statutory penalty for a single
violation of the TCPA is $500, although the penalty can increase to $1,500 per
violation if the Company is found to have willfully or knowingly violated these
laws. The case is currently pending in the Richmond County, Georgia, Superior
Court, and the Company is complying with the Court's order for discovery. A
hearing on class certification is currently scheduled for May 3, 2005. The
Company is uncertain as to the outcome of this case.

     In the normal course of business, Penton 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 Penton's financial statements, management is unable to estimate the
magnitude or financial impact of claims and lawsuits that may be filed in the
future.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND
         ISSUER REPURCHASES OF EQUITY SECURITIES

     In June 2003, the Company was notified by the New York Stock Exchange
("NYSE") that it would begin delisting procedures of the Company's common stock.
The NYSE reached its decision because Penton had been unable to comply with the
NYSE's continued listing criteria, which include minimum levels for stock price,
market capitalization, and stockholders' equity. The NYSE took this action at
that time because Penton was not expected to be able to increase its equity to
the minimum listing requirements within the required time frame. On June 17,
2003, Penton's stock began trading on the Over-the-Counter Bulletin Board under
the symbol PTON.

     The following tables set forth, for the periods indicated, the high and low
sales prices for Penton's common stock.

     The Company had approximately 812 record holders of its common stock on
March 31, 2005.

     Our dividend policy is determined by our Board of Directors. Any decision
to pay dividends in the future will be made by our Board of Directors based upon
the results of our operations and financial condition and such other matters as
our Board of Directors considers relevant. The terms of our outstanding
convertible preferred stock, however, limit the payment of dividends on the
common stock until all accrued dividends have been paid on the convertible
preferred stock. We may not pay accrued dividends on the convertible preferred
stock unless approved by the holders of not less than 75% of the then
outstanding shares of the convertible preferred stock. Furthermore, the
Company's ability to pay dividends is restricted by certain covenants in our
bond indentures and credit facility. No dividends were paid in 2003 or 2004.

     As discussed in Note 2 -- Restatement, of the notes to the consolidated
     financial statements appearing elsewhere herein, adjustments made to the
     2003 and 2002 financial statements were classified as "deferred tax
     adjustments" and "other accounting adjustments."

     The increase in net loss in 2003 was due primarily to an increase of $6.8
     million in income tax expense due to the correction of our deferred taxes
     offset in part by a decrease of $2.0 million in impairment of asset charges
     as our minority interest in consolidated subsidiaries balance should have
     been reduced when certain assets contributed in 2002 by our minority
     interest partner were impaired.
                                        26
<PAGE>

     The increase in net loss in 2002 was due primarily to an increase of $10.1
     million in income tax expense due to the correction of our deferred taxes.

     The amortization of the deemed dividend and accretion Preferred stock
     decreased by $0.3 million in 2003 and increased by $0.3 million in 2002. In
     June 2003, it was discovered that the Company should not have only been
     accruing the dividends on the preferred stock from the time of issuance but
     should have also been accreting some of the preferred stock.

     Total assets increased in 2003 due to the establishment of a receivable and
     corresponding payable for $4.6 million related to the tentative settlement
     in the Meckler lawsuit between Penton's insurance carrier and the
     plaintiff. This amount was offset in part by a reduction of $2.6 million in
     accounts receivable related to certain trade show receivables that were
     recorded at their full contract amounts even though the contract stipulated
     that only a portion of the contract was due.

     Total assets increased in 2002 due to the establishment of a deferred tax
     asset of $0.5 million and $0.2 million in tenant reimbursements, which were
     improperly classified in 2001.

     The increase in long-term liabilities and deferred credits in 2003 and 2002
     is due primarily to the establishment of a deferred tax liability of $6.8
     million and $10.1 million, respectively. The 2003 liability also includes
     the offset adjustments related to the $4.6 Meckler lawsuit and $2.6 trade
     show receivable adjustments discussed above.

 (2) Operating expenses include the following charges: (a) impairment of
     Internet asset charges of $2.1 million in 2000; (b) impairment of asset
     charges of $39.7 million, $43.8 million, $223.4 million and $59.8 million,
     in 2004, 2003, 2002 and 2001, respectively; (c) restructuring and other
     charges of $6.2 million, $5.9 million (as restated), $16.4 million, and
     $18.8 million in 2004, 2003, 2002 and 2001, respectively (of which $1.0
     million is classified with discontinued operations in 2002); (d) loss on
     sale of properties of $0.9 million in 2004 and 2002, respectively; and (e)
     amortization of goodwill in 2000 and 2001.

 (3) In 2004 and 2003 (as restated), for income taxes includes a $33.9 million
     and $25.8 million charge, respectively, to establish a valuation allowance
     for our net deferred tax assets and net operating loss carryforwards.

 (4) Included in interest expense in 2003 is approximately $0.9 million related
     to the write-off of unamortized financing fees associated with the
     commitment reduction of our credit facility revolver in January 2003 from
     $40.0 million to $20.1 million. Also included in interest expense in 2003
     is approximately $1.0 million related to the write-off of unamortized
     financing fees associated with the replacement of our senior secured credit
     facility in August 2003 with a new four-year loan agreement. Included in
     interest expense in 2002 is approximately $0.7 million related to the
     write-off of unamortized finance fees associated with the commitment
     reduction of our credit facility revolver from $185.0 million to $40.0
     million in March 2002 and approximately $1.4 million related to hedging
     activities.

 (5) Included in cash flows from operations in 2003 is a tax refund of $52.7
     million.

 (6) In 2002, Penton adopted Statement of Financial Accounting Standard ("SFAS")
     No. 142 and recorded a transitional one-time, non-cash goodwill impairment
     charge of $39.7 million related to two of our reporting units, which are
     part of our Technology segment. The charge was recorded as a cumulative
     effect of accounting change.

 (7) In 2002, the amortization of deemed dividend and accretion of preferred
     stock included a $42.1 million, one-time, non-cash charge, which was the
     result of stockholder approval on May 31, 2002 to remove the 10-year
     mandatory redemption date on our convertible preferred stock.

 (8) The extinguishment of debt of $0.3 million in 2002 consists of a gain on
     the purchase of $10.0 million face value of our Subordinated Notes in March
     2002, at prevailing market prices, offset by the write-off

                                        27
<PAGE>

     of unamortized deferred financing costs associated with the payoff of our
     term loan A and term loan B facilities.

 (9) Penton sold its stock in Jupitermedia Corporation and recognized a gain
     from its sale of $1.5 million and $110.2 million in 2002 and 2000,
     respectively.

(10) Included in 2001 other, net on the consolidated income statement is
     approximately $0.8 million of proceeds related to the write-off of Internet
     investments for LeisureHub.com. In 2000 other, net includes a loss of
     approximately $9.5 million related to the Company reducing the carrying
     value of its investment in Cayenta and LeisureHub.com to zero.

(11) 2001 reported total assets of $700.4 million and reported total long-term
     liabilities and deferred credits of $369.8 million were restated to $700.6
     million and $370.0 million, respectively, due to approximately $0.2 million
     in tenant reimbursements, which were improperly classified.

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

     Set forth below is a discussion and analysis of our financial condition and
results of operations. You should read this discussion and analysis in
conjunction with the audited consolidated financial statements of Penton Media,
Inc. included elsewhere in this document. This "Management's Discussion and
Analysis of Financial Condition and Results of Operations" contains
forward-looking statements. See "Forward-Looking Information (Safe Harbor
Statement)" and "Risk Factors" in Item 1 of this annual report on Form 10-K for
a discussion of the uncertainties, risks and assumptions associated with these
statements.

OVERVIEW

     Penton Media is a diversified business-to-business ("b-to-b") media
company. We provide media products that deliver proprietary business information
to owners, operators, managers and professionals in the industries we serve.
Through these products, we offer industry suppliers multiple ways to reach their
customers and prospects as part of their sales and marketing efforts. In June
2004, the Company appointed David B. Nussbaum as Chief Executive Officer
("CEO"). Mr. Nussbaum is now Penton's chief operating decision maker. After
reviewing the Company's operations, Mr. Nussbaum and the executive team
implemented a change in the Company's reportable segments effective in the third
quarter of 2004 to conform with the way the Company's businesses are now
assessed and managed. The Company is structured along segment and industry lines
rather than by product lines. This enables us to promote our related group of
products, including publications, trade shows and conferences, and online media
products, to our customers. As a result of this change in reportable segments,
all prior periods were recast to conform with the new segment format. Our five
principal segments and the industries they serve are as follows:

<Table>
           <S>                                <C>                                   <C>
           INDUSTRY                           TECHNOLOGY
           Manufacturing                      Business Technology
           Design/Engineering                 Aviation
           Mechanical Systems/Construction    Enterprise Information Technology
           Government/Compliance              Electronics

           LIFESTYLE                          RETAIL
           Natural Products                   Food/Retail
                                              Hospitality
           INTERNATIONAL
           United Kingdom
</Table>

     We believe we have leading media products in each of the industries we
serve. We are structured along segment and industry lines rather than by product
lines. This enables us to promote our related media products to our customers.

                                        28

     The b-to-b media industry suffered significant declines in 2001 and 2002 as
the weak economy, disappointing corporate profits and the lingering effects of
geopolitical events pressured many companies to reduce costs, including
marketing spending.

     As the economy strengthened in 2003 and 2004 and companies gained
confidence in their business results and re-engaged in marketing investment,
b-to-b media experienced growth, albeit modest. Advertising pages in U.S. b-to-b
magazines grew 1.4% and spending in b-to-b magazines grew by 3.8% in 2004,
according to the Business Information Network ("BIN"). Net square footage of
exhibit space at trade shows held in North America grew by 1.5%, the number of
exhibiting companies expanded 1.6%, and attendance grew by 2.7%, according to
Tradeshow Week magazine. Many b-to-b media companies also experienced
significant growth in their online media product lines, as marketers continued a
trend of allocating increased spending to a wide range of Web-based
opportunities.

     Mirroring the industry's modest growth trends, Penton's revenues in 2004
expanded approximately 3%. It is the first year since 2000 that revenues grew
year-on-year. Publishing revenues continued a declining trend; however, the rate
of decline was only 2.9% after double-digit declines for the past two years.
While we believe that our print advertising business has stabilized, and we do
not expect it to grow significantly in the near term. We are planning for modest
growth in 2005 but continue to focus on margin improvement of this business
through process efficiencies and improved vendor contracts. Growth in the
Company's event and online business also followed industry trends, with revenues
expanding 16.2% and 27.0%, respectively. Management expects the revenue growth
rate for these product lines to outpace the growth rate for publishing
throughout 2005.

     We continue to note that b-to-b marketers are employing a range of
integrated media solutions to achieve their marketing objectives, and that they
are highly interested in media solutions that provide a measurable return on
their marketing investment. Because electronic media and customized media offer
unique return-on-investment metrics, marketers are allocating more significant
portions of their media spending to these products.

     Penton management has responded to these trends by expanding our online
media infrastructure. We appointed a senior executive in the summer of 2004 to
lead our electronic media business strategy initiatives and restructure our
online media development teams to leverage our internal staff and accelerate
product development. We also have added online media product management and
sales and marketing competencies in certain business units to accommodate
growing volumes. In addition, we have added to our custom media development and
project management staffs to help facilitate growth in this service area.

     We are focused on applying proper resources to these efforts, even as we
have significantly reduced costs of the business over the past few years and
continue to recognize the importance of continued cost management to expand
profits and margins. Our intention is to center ongoing cost-reduction efforts
primarily on overhead areas and to apply optimal staffing and investment
resources to our products and our customer service areas.

MANAGEMENT OBJECTIVES

     Management's key objective is to restore value for our stockholders. We are
focused on conserving cash and maintaining sound liquidity. We reduced long-term
debt from $329.1 million to $323.6 million in February 2005 through the
repurchase of $5.5 million face value of our Subordinated Notes on the open
market. The purchase will result in a reduction of the Company's annual interest
payments by $0.6 million. We continue to work with our Board of Directors on
strategies for strengthening the Company's balance sheet.

     Operationally, we are focused on driving revenues and profitability with
the goal of reaching a positive net cash flow position in the near term.

     Over the past four years, we have responded to the severe downturn in our
financial performance by reducing the Company's fixed costs by reducing our net
headcount by 56.5% in the period 2001 to 2004, including 71 positions in 2004;
freezing our pension plan and introducing a defined contribution plan; reducing
capital spending; outsourcing certain corporate and division functions;
renegotiating key vendor contracts; and
                                        29
<PAGE>

implementing process improvements. We continue to manage a disciplined
cost-management effort throughout the Company, with a particular focus on
overhead areas.

     Our critical focus is on driving revenue growth, so that the operating
leverage that our cost savings has created results in improved cash flows and
returns the Company to a positive net cash flow position. The senior operating
managers of the business are executing strategies that we believe address unique
incremental revenue generation opportunities within their respective markets. We
expect to invest in such opportunities, including certain small, yet strategic
acquisitions and a range of new product launches.

SIGNIFICANT EVENTS

Restatement of Financial Statements

     On March 24, 2005, the Company's management concluded that the Company's
previously issued consolidated financial statements should be restated to
increase income tax expense to correct the computation of our valuation
allowance for deferred tax assets. Management reached this conclusion following
a comprehensive review of the Company's deferred tax assets and deferred tax
liabilities. The Company determined that certain deferred tax liabilities had
been incorrectly offset against its deferred tax assets. Under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes," taxable
temporary differences related to indefinite-lived intangible assets or
tax-deductible goodwill (for which reversal cannot be anticipated) should not be
offset against deductible temporary differences for other indefinite-lived
intangible assets or tax-deductible goodwill when scheduling reversals of
temporary differences.

     The Company evaluated the materiality of the correction on its consolidated
financial statements using the guidelines of SAB 99 and concluded that the
cumulative effects of the corrections were material to its annual consolidated
financial statements for 2004, 2003 and 2002 and the related quarterly
consolidated financial statements for such periods. As a result, the Company
concluded that it will restate its previously issued consolidated financial
statements to recognize the impact of the correction, as well as other
accounting adjustments that were deemed in earlier periods to be immaterial.

     These financial statements have been restated to reflect adjustments to the
Company's previously reported financial information on Form 10-K for the years
ended December 31, 2003 and 2002. The Company's 2004 and 2003 quarterly
financial information also has been restated to reflect adjustments to the
Company's previously reported financial information on Form 10-Q for the
quarters ended March 31, 2004, June 30, 2004 and September 30, 2004. As a result
of the restatement, the Company identified adjustments through the filing date
of this Form 10-K that were required to be recorded which increased previously
reported stockholders' deficit at December 31, 2003 and September 30, 2004 by
$15.4 million and $17.1 million (unaudited), respectively. For additional
information on the restatement, see Note 2 -- Restatement, in the notes to
consolidated financial statements included herein.

     The Company will restate the quarterly periods ended March 31, 2004; June
30, 2004; and September 30, 2004 on Forms 10-Q/A to be filed as expeditiously as
possible following the filing of the Form 10-Q for the quarterly period ended
March 31, 2005.

Senior Subordinated Notes Repurchase

     In February 2005, the Company repurchased $5.5 million par value of its
10 3/8% senior subordinated notes for a total of $3.9 million, including $0.1
million of accrued interest, using excess cash on hand. These notes were
purchased in the open market and were trading at 69% of their par value at the
time of purchase. The repurchase resulted in a gain of approximately $1.6
million.

Loan and Security Agreement

     On March 30, 2005, the Company received an extension until May 15, 2005 to
deliver its annual audited financial statements to its Lender Group. The terms
of our Loan and Security Agreement require us to provide annual audited
financial statements within 90 days of the end of our fiscal year.

                                        30
<PAGE>

     On April 1, 2005, the Company borrowed $6.0 million under the Company's
Loan and Security Agreement. The proceeds were used to pay the interest due on
April 1 under the Company's Secured Notes.

Sale of Properties

     In December 2004, the Company completed the sale of 70% of its interest in
PM Germany, a consolidated subsidiary, to Neue Medien Ulm Holdings GmbH ("Neue
Medien") for $0.8 million in cash. The sale did not qualify as discontinued
operations under SFAS No. 144, "Accounting for the Impairment or Disposal of
Long-Lived Assets" ("SFAS 144"). Consequently, the related loss on sale of $0.9
million is included in loss on sale of properties, on the accompanying
consolidated statements of operations. The Company retains a 15% interest in PM
Germany, which includes a call/put option. The Company accounts for its
investment using the cost method, as the Company does not exercise significant
influence.

Exchange of Convertible Preferred Stock

     On September 13, 2004, the Company filed a Certificate of Designations
governing a new series of convertible preferred stock, $0.01 par value (the
"Series C Preferred"), with the Secretary of State for the State of Delaware.
The Series C Preferred stock was exchanged on a share-for-share basis with the
Company's Series B Convertible Preferred Stock, $0.01 par value (the "Series B
Preferred"). The Certificate of Designations for the Series C Preferred stock is
identical to the Series B Preferred stock Certificate of Designations except
that:

     - the new series allows for the sharing of the liquidation preference with
       the new Series M Preferred Stock (discussed below),

     - certain technical and correcting amendments have been made to the
       Certificate of Designations for the Series C Preferred stock, including
       fixing the formula used to calculate the "Change of Control Cap" (as
       defined in the Series C Preferred stock Certificate of Designations), and

     - certain conforming changes were made to the Series C Preferred stock
       Certificate of Designations to account for the fact that the Series C
       Preferred stock was issued in exchange for the Series B Preferred stock.

Series M Preferred Stock

     On September 13, 2004, the Company filed a Certificate of Designations for
a new series of preferred stock, $0.01 par value (the "Series M Preferred"),
with the Secretary of State for the State of Delaware. The Board of Directors of
the Company created the Series M Preferred stock for issuance to certain
employees of the Company as a long-term incentive plan to incentitize management
by giving them an equity stake in the performance of the Company. The Series M
Preferred stock is limited to 150,000 shares, of which 68,625 shares have been
issued as of December 31, 2004. The Series M Preferred stock is treated under
fixed plan accounting and is classified in the mezzanine section of the balance
sheet because redemption is outside the control of the Company.

     Among other rights and provisions, the Series M Preferred stock Certificate
of Designations provides that the holder of each share will receive a cash
distribution upon any liquidation, dissolution, winding-up or change of control
of the Company. The amount of such distribution is first a percentage of what
the holders of Series C Preferred stock and second a percentage of what the
holders of the Company's common stock would receive upon such liquidation,
dissolution, winding-up or change of control.

New Chairman and Chief Executive Officer

     On June 21, 2004, the Board of Directors announced the appointment of David
B. Nussbaum as CEO of Penton. Mr. Nussbaum succeeded Thomas L. Kemp. The Company
had announced on March 24, 2004 that Mr. Kemp would be leaving the Company.

                                        31
<PAGE>

     Mr. Nussbaum was previously an executive vice president with the Company
and president of the Company's former Technology and Lifestyle Media Division.
Mr. Nussbaum joined Penton in 1998 after an 18-year career with Miller Freeman,
Inc., where he was a senior vice president responsible for its New York
Division.

     In addition, on June 14, 2004, the Board of Directors named Royce Yudkoff
as its non-executive chairman. Mr. Yudkoff is a co-founder of ABRY Partners,
LLC, a media-focused private equity investment firm based in Boston, and
currently serves as its president and managing partner.

Board of Director Changes

     Effective at the annual meeting of stockholders on July 15, 2004, the
number of board members was reduced from 11 to 8. With this reduction, the
holders of the Series C Preferred stock constitute a majority of the Company's
Board of Directors. Upon the Series C Preferred stockholders obtaining this
majority, the conversion price of the Company's convertible preferred stock
adjusted back to $7.61 (see Preferred Stock Leverage Ratio Event of
Non-Compliance below).

     The Company announced on June 14, 2004, that the Series C Preferred
stockholders had appointed Mr. Yudkoff as a director to replace Daniel C. Budde,
who resigned effective June 11, 2004. At the same meeting, the Board named Mr.
Yudkoff its non-executive chairman.

     At the Company's Board of Directors meeting held on July 21, 2004, the
Board named Mr. Nussbaum as a director and decreased the number of directors to
seven.

Management Restructuring

     On June 24, 2004, the Company announced a reorganization of its corporate
leadership structure. These changes, which are aimed at accelerating product and
service development, driving revenue growth, and flattening the Company's
organizational structure, included the following actions:

     - Daniel J. Ramella, president and Chief Operating Officer of Penton Media,
       Inc. and president of the Company's Industry Media Division, and William
       C. Donohue, who managed the Retail Media group operation, left the
       Company as of June 30, 2004.

     - David B. Nussbaum, the Company's new CEO, assumed the senior operating
       responsibilities for the Industry group and Darrell Denny, president of
       the Company's IT Media and Lifestyle Media groups, assumed the operating
       responsibilities for the Retail Media, IT Media and Lifestyle Media
       groups.

     - Eric Shanfelt, director of eMedia strategy for Penton's IT Media Group
       and New Hope Natural Media business, assumed the newly created corporate
       position of vice president of eMedia Strategy as Penton moves to expand
       its online media portfolio.

Senior Executive Bonus and Termination Benefits

     As noted above, on June 21, 2004, Penton's Board of Directors announced the
appointment of David B. Nussbaum as CEO of the Company. In addition to the
Company's standard executive incentive and benefit package, Mr. Nussbaum
received a signing bonus of approximately $1.7 million and 30,000 shares of
Series M Preferred stock. In addition, the Board accelerated the vesting of
135,000 deferred shares granted to Mr. Nussbaum on February 3, 2004. Mr.
Nussbaum used the net proceeds from his signing bonus and 288,710 shares of
Penton common stock, which were returned to the Company, to repay his executive
loan balance in full.

     On March 24, 2004, the Company announced that its Chairman and CEO, Thomas
L. Kemp, would be leaving the Company. Mr. Kemp's employment was terminated
effective June 30, 2004, and on July 1, 2004,

                                        32
<PAGE>

Mr. Kemp and the Company signed a Separation Agreement and General Release. Mr.
Kemp's separation agreement includes the following:

     - A lump-sum payment of approximately $2.3 million, of which $0.8 million
       has been placed in escrow. Included in this payment is severance of
       approximately $1.8 million per Mr. Kemp's employment agreement, $0.3
       million related to performance units granted on May 22, 2003, and $0.2
       million related to the settlement of Mr. Kemp's accrued supplemental
       executive retirement plan obligation;

     - The accelerated vesting of 100,000 stock options granted to Mr. Kemp
       prior to his termination making them immediately exercisable; and

     - The immediate vesting of 125,000 performance shares in accordance with
       the terms of his performance share agreement dated February 5, 2002.

     In addition, the Board and Mr. Kemp agreed upon a number of provisions
related to Mr. Kemp's outstanding executive loan balance. The underlying goal of
these provisions was to mitigate any tax exposure to the Company should the loan
be discharged at a future date. Specifically, $0.8 million of the lump-sum
payment described above has been placed in escrow and will be returned to Mr.
Kemp only if he pays off the entire loan balance by its due date. Furthermore,
Mr. Kemp has granted Penton a security interest in approximately 1.1 million
shares of Penton common stock. These pledged securities could be transferred to
Penton's ownership under certain circumstances and used to pay down the
outstanding loan balance.

     On June 28, 2004, Mr. Kemp was granted 514,706 deferred shares that vested
on January 3, 2005. In return for these shares, Mr. Kemp agreed to comply with
the terms of certain restrictive covenants, including a non-compete and a
non-solicitation covenant.

     At December 31, 2004, $2.7 million in termination benefits related to Mr.
Kemp have been included in selling, general and administrative expenses on the
consolidated statements of operations.

     On June 27, 2004, the Company announced that its President and Chief
Operating Officer, Daniel J. Ramella, would be leaving the Company as part of a
management restructuring plan. Mr. Ramella's employment was terminated effective
June 30, 2004, and on July 1, 2004, Mr. Ramella and the Company signed a
Separation Agreement and General Release agreement. Mr. Ramella's separation
agreement includes the following:

     - A lump-sum payment of approximately $1.7 million. Included in this
       payment is severance of approximately $1.4 million per Mr. Ramella's
       employment agreement, $0.1 million related to performance units granted
       on May 22, 2003, and $0.2 million related to the settlement of Mr.
       Ramella's accrued supplemental executive retirement plan obligation;

     - The accelerated vesting of 139,999 stock options granted to Mr. Ramella
       prior to his termination making them immediately exercisable; and

     - The immediate vesting of 90,000 performance shares in accordance with the
       terms of his performance share agreement dated February 5, 2002.

     In addition, the Board agreed to discharge the balance of Mr. Ramella's
$2.6 million executive loan in return for the full and final settlement of any
claims Mr. Ramella may have had against the Company.

     At December 31, 2004, $1.4 million in termination benefits related to Mr.
Ramella were included in restructuring and other charges on the consolidated
statements of operations.

PREFERRED STOCK LEVERAGE RATIO EVENT OF NON-COMPLIANCE

     At December 31, 2004, an event of non-compliance continues to exist under
our Series C Preferred stock because the Company's leverage ratio of 11.8
(defined as debt less cash balances in excess of $5.0 million plus the
liquidation value of the preferred stock and unpaid dividends divided by
adjusted EBITDA) exceeds 7.5. Upon the occurrence of this event of
non-compliance, the 5% per annum dividend rate on the convertible preferred
stock increased by one percentage point as of April 1, June 30, September 28 and
December 27,

                                        33
<PAGE>

2003 and March 26, 2004 to the current maximum rate of 10% per annum. The
dividend rate will adjust back to 5% as of the date on which the leverage ratio
is less than 7.5. The leverage ratio event of non-compliance does not represent
an event of default or violation under any of the Company's outstanding notes or
the loan agreement. As such, there is no acceleration of any outstanding
indebtedness as a result of this event. In addition, this event of
non-compliance and the resulting consequences have not resulted in any cash
outflow from the Company.

     If the Company had been sold on December 31, 2004, the bondholders would
have been entitled to receive $335.8 million and the Series C Preferred
stockholders would have been entitled to receive $122.5 million before the
common stockholders would have received any amounts for their common shares. The
amount the Series C Preferred stockholders would be entitled to receive could
increase significantly in the future under certain circumstances. Stockholders
are urged to read the terms of the Series C Preferred stock carefully.

RESULTS OF OPERATIONS

     Since early 2001, the Company, like many of our customers and competitors,
has been adversely impacted by the broad economic slowdown. The b-to-b media
industry, in particular, has experienced severe declines as companies have
reduced their overall marketing expenditures in response to the global economic
slowdown and the resulting pressure on their businesses.

     The overall slowdown in b-to-b media has impacted our margins and operating
income. As a result of sharply reduced revenues across our magazines and trade
shows, we recorded special charges of $51.3 million, $57.3 million, and $239.7
million in 2004, 2003 (as restated) and 2002, respectively, primarily for asset
impairments and restructuring and other costs resulting from our cost reduction
initiatives and the closure of certain facilities.

REVENUES

     We recognize advertising revenues from Penton's trade magazines in the
month the publications are mailed. Amounts received in advance of trade shows
and conferences are deferred and recognized in the month the events are held.
Online media revenues, primarily advertising revenues, are recognized in the
period the obligation is fulfilled or delivered.

     Our magazines generate revenues primarily from the sale of advertising
space. Our magazines are primarily controlled circulation and are distributed
free of charge to qualified subscribers in our target industries. Subscribers to
controlled-circulation publications qualify to receive our trade magazines by
verifying their responsibility for specific job functions, including purchasing
authority. We survey our magazine subscribers annually to verify their
continuing qualification. Trade show exhibitors pay a fixed price per square
foot of booth space. In addition, we receive revenues from attendee fees at
trade shows and from exhibitor sponsorships of promotional media. Our
conferences are supported by either attendee registration fees or marketer
sponsorship fees, or a combination of each. Online media revenues are generated
from a variety of sources, such as: advertising on Web sites, including
search-engine advertising; sponsorship of Web conferences; advertising in and
sponsorships of electronic newsletters; sponsorship of content on Web sites and
in electronic books; and listings in online databases and directories.

     The following table summarizes our net revenues:

     As the general economy and many of the markets Penton serves strengthened
in 2004, Penton's revenues stabilized. Overall revenues for the Company grew
3.2% in 2004, after a year-over-year decline of 12.3% in 2003 and double-digit
declines in 2002 and 2001. Publishing revenues, which have experienced the most
significant declines in the most recent economic downturn, stabilized in 2004,
with a modest 2.9% decline

                                        34
<PAGE>

compared with a 10.6% decline in 2003 over 2002. The Company's manufacturing
titles experienced revenue growth in 2004, reversing declines in 2003. Magazines
serving enterprise IT markets continued to struggle in 2004; however, we are
beginning to see improvements in those titles in 2005.

     Mirroring b-to-b media industry trends, in-person media revenues improved
by 16.2% in 2004 compared with a 22.0% revenue decline in 2003. Online media
revenues expanded 27.0%, compared with 9.2% in 2003.

     Visibility continues to be somewhat limited for b-to-b magazine
advertising, and marketers are continuing to direct greater portions of their
expenditures toward a broader variety of media, particularly online media. As
such, we are planning for modest growth in publishing revenues through the near
term, and expect revenue growth rates for trade shows and conferences and online
media to outpace publishing revenue growth in 2005.

     Revenue trends within each segment are further detailed below in the
segment discussion section.

2004 vs. 2003

     Total revenues increased $6.7 million, or 3.2%, from $206.0 million in 2003
(as restated) to $212.7 million in 2004. The increase was due primarily to an
increase in trade show and conference revenues of $7.2 million, or 16.2%, from
$44.2 million for 2003 to $51.4 million for 2004, and an increase in online
media revenues of $3.7 million, or 27.0%, from $13.9 million for 2003 to $17.6
million for 2004. This increase was partially offset by a decrease in publishing
revenues of $4.3 million, or 2.9%, from $147.9 million for 2003 (as restated) to
$143.6 million for 2004.

     The $4.3 million, or 2.9%, decrease in publishing revenues was due
primarily to decreases in advertising revenues and revenues from subscriptions
and list rentals. The two primary reasons for the decrease in magazine revenues
is the period-on-period decrease in our IT Media publications and the
elimination of our Internet World magazine in June of 2003, which generated
revenues of approximately $1.1 million in 2003.

     The $3.7 million, or 27.0%, increase in online media revenues was due
primarily to increases in sponsorship revenues for electronic newsletters, Web
conferences and sponsorships of content on Web sites and in electronic books.
Period-on-period increases were realized by most of Penton's online media
products, with Windows IT Pro, IndustryWeek and Business Finance electronic
media generating the largest increases.

     The $7.2 million, or 16.2%, increase in trade show and conference revenues
for 2004 compared with the same prior-year period was due primarily to an
increase in sponsorship and attendee revenues offset by a decrease in exhibitor
revenues from booth rentals. Increased trade show and conference revenues were
due primarily to: (i) the improved revenue for two of our fall technology
conferences -- SQL Server and ASP/VS Connections; (ii) the year-on-year results
of a highly successful Natural Products Expo West show held in March 2004; (iii)
the biannual Motion & Control event, which was held in the United Kingdom in
2004; and (iv) the year-on-year results of our Windows IT Pro roadshows.

     Revenue trends within each segment are further detailed below in the
segment discussion section.

2003 vs. 2002

     Total revenues decreased $28.9 million, or 12.3%, from $234.9 million in
2002 (as restated) to $206.0 million in 2003 (as restated). The decrease was due
primarily to a decrease in publishing revenues of $17.6 million, or 10.6%, from
$165.5 million in 2002 (as restated) to $147.9 million in 2003 (as restated) and
a decrease in trade show and conference revenues of $12.5 million, or 22.0%,
from $56.7 million in 2002 to $44.2 million in 2003. Online media revenues
increased $1.2 million, or 9.2%, from $12.7 million in 2002 to $13.9 million in
2003. Included in revenues for 2002 were publishing revenues of $1.3 million,
trade show and conference revenues of $5.4 million and online media revenues of
$0.8 million associated with properties sold in December 2002, which were not
classified as discontinued operations.

     The $17.6 million decrease in publishing revenues was due primarily to a
decrease in our Industry and Technology segments. Our manufacturing and
design/engineering portfolios accounted for $6.9 million of the decrease, while
our Internet technology, electronics and enterprise information technology
portfolios accounted for an additional $11.9 million of the decrease. The
decrease was offset by improvements in our Germany operations publications.
Overall, advertising revenues accounted for 9.0% of the 10.6% publishing revenue
decrease as companies remained cautious about their marketing budgets.
Subscription revenues, which represent about 6.5% of our total 2003 publishing
revenues, decreased by approximately $1.7 million when compared with 2002. List
rental revenues and licensing revenues also showed declines in 2003 when
compared with 2002.

     The $12.5 million decrease in our trade show and conference revenues was
due primarily to a decrease of $12.4 million in our Technology segment and a
decrease of $2.7 million in our Industry segment. These declines were partially
offset by revenue improvements in our Lifestyle segment of $0.9 million and an
increase in our Retail segment of $1.7 million. Exhibitor revenues, which
represent about 69.0% of 2003 trade show and conference revenues, declined
nearly 24.2%, due primarily to a decrease in booth rentals. Exhibitor
cancellation revenues declined $3.3 million from $4.5 million in 2002 to $1.2
million in 2003. Attendee revenues declined nearly $1.9 million; however,
sponsorship revenues more than offset this decrease.

     The $1.2 million increase in online media revenues was due primarily to an
increase in our International segment of $1.0 million and an increase in our
Industry segment of $0.4 million, offset by a decrease of $0.2 million in our
Technology segment. Most of the increase in online media revenues was due to
increases in electronic newsletters and Web conferences.

<PAGE>

increase in editorial, production and circulation expenses for the year ended
2004 compared with the same period in 2003 primarily reflect costs associated
with our biannual Motion & Control event which was held in 2004; costs
associated with a full year of Logistics Today, which was launched in September
2003; and costs associated with an increase in the number of roadshows held
during 2004. These cost increases were partially offset by lower headcount and
personnel-related costs, lower postage costs, and lower paper and printing
costs. Expenses in 2003 include some costs attributable to unprofitable
properties, which have been eliminated, particularly Internet World magazine.

     The decrease in editorial, production and circulation expenses for 2003
compared to 2002 primarily reflects the effects of our expense reduction
initiatives including, lower headcount and personnel-related costs and the
elimination of some unprofitable properties. The decrease also reflects lower
costs due to decreases in volume, as well as the sale of four properties in
December 2002, which were not classified as discontinued operations. These
properties accounted for $3.1 million of the decrease.

</Table>

     Our selling, general and administrative ("SG&A") expenses include personnel
costs, independent sales representative commissions, product marketing and
facility costs. Our SG&A expenses also include costs of corporate functions,
including accounting, finance, legal, human resources, information systems, and
communications. The decrease in SG&A expenses for the year ended December 31,
2004 compared with the same period in 2003 was due primarily to a $2.7 million
charge related to executive separation costs for Mr. Kemp, who left the Company
on June 30, 2004; a signing bonus of $1.7 million paid to Mr. Nussbaum (net of a
reversal of $1.1 million related to Mr. Nussbaum's executive loan); and $0.4
million in other executive-related separation costs. These additional costs were
partially offset by the restructuring efforts undertaken in 2003 and 2004, which
have resulted in lower headcount and personnel-related costs and lower facility
costs.

     The decrease in SG&A expenses for 2003 compared with 2002 was due primarily
to cost savings associated with additional office closings completed in the
second half of 2002 and in 2003 as well as other facility cost reductions;
additional staff reductions completed in 2002 and 2003; continued cost
reductions across all corporate functions; continued division overhead cost
reduction; a pension plan curtailment gain of $2.2 million recognized in 2003;
reduced marketing expenses; and the sale of properties in December 2002, which
were not classified as discontinued operations. These properties accounted for
$5.1 million of the decrease.

2004 IMPAIRMENTS

     During the third quarter of 2004, the Company completed its annual goodwill
impairment review in accordance with SFAS 142, which resulted in a non-cash
charge of $37.8 million and reduced the carrying value of goodwill for two
reporting units in our Technology segment and one reporting unit in our
International segment. As a result of the impairment of goodwill for three of
our seven reporting units, the Company also completed an assessment at September
30, 2004 of its other intangibles in accordance with SFAS No. 144, "Accounting
for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144"), and recorded
a non-cash charge of $1.9 million. The 2004 goodwill impairment charge is due
primarily to lower than expected future cash flows in two of our reporting units
in our Technology segment and by lower than expected future cash

                                        37
<PAGE>

flows in our International segment. Impaired long-lived assets in 2004 relate to
exhibitor lists and advertising relationships in our Information Technology
market due to lower than expected revenues and lower retention rates.

2003 IMPAIRMENTS

     During the third quarter of 2003, we completed our annual impairment test
of goodwill and other intangible assets under the provisions of SFAS 142 and
recorded a non-cash charge of $37.6 million related to the reduction of the
carrying value of goodwill in three of our seven identified reporting units. We
utilized a third-party valuation company to assist management in determining the
fair value of the reporting units. Two of the reporting units are part of our
Technology segment and one of the reporting units is part of our Retail segment.
The fair value of our reporting units was determined using the income approach,
which is similar to the discounted cash flows approach.

     Due to the impairment of goodwill in three of our seven reporting units, as
noted above, we also completed an assessment in accordance with SFAS 144 at
September 30, 2003 (as restated) and recorded non-cash charges of $6.2 million.
These charges primarily relate to the write-off of trade names and advertiser
relationships for properties in our Technology segment. The fair value of the
asset groups was determined using the income approach.

2002 IMPAIRMENTS

     During the third quarter of 2002, we completed our transitional goodwill
impairment test under SFAS 142 for January 1, 2002 and recorded a non-cash
charge of $39.7 million to reduce the carrying value of goodwill for two of our
seven identified reporting units. Penton utilized a third-party valuation
company to determine the fair value of its reporting units. Both of these
reporting units are part of the Company's Technology segment. The charge is
reflected as a cumulative effect of accounting change in the accompanying
consolidated statements of operations.

     During the third quarter, a number of events occurred that indicated that a
possible additional impairment of goodwill might exist. These events included
lower-than-expected revenues and adjusted EBITDA results for the year; a letter
from the NYSE indicating that the Company had fallen below minimum listing
standards; a significant decline in the Company's stock price; and the decision
by management to potentially sell or dispose of certain non-core assets. As a
result of these triggering events and circumstances, the Company completed an
additional SFAS 142 impairment review at September 30, 2002. This review
resulted in a non-cash charge of approximately $203.3 million, further reducing
the carrying value of goodwill for these two reporting units in our Technology
segment. The fair value of the reporting units for the initial and interim
impairment test was determined using the income approach.

     Because of the events noted above, we also completed an assessment in
accordance with SFAS 144 and recorded a non-cash charge of $20.0 million. This
charge primarily relates to the write-off of mailing/exhibitor lists and sponsor
relationships for properties in our Technology segment. The fair value of the
asset groups was determined using the income approach.

     EITF 00-23, "Issues Related to the Accounting for Stock Compensation under
APB Opinion No. 25 and FASB Interpretation No. 44," requires that once a Company
forgives all or part of a recourse note it must consider all other existing
recourse notes as nonrecourse prospectively (variable accounting). Consequently,
the Company recognized $0.1 million in additional paid-in capital in excess of
par equal to the fair market value of the stock issued in conjunction with the
establishment of the executive loans. In addition, the Company recorded a $1.8
million provision for loan impairment on the remaining unreserved loan balance.

                                        38
<PAGE>

Additionally, the Company reversed the $1.1 million reserve established in June
2003 related to Mr. Nussbaum's loan against his signing bonus of $1.7 million,
which was recorded in selling, general and administrative expenses on the
consolidated statements of operations. Going forward, all future awards
exercised with recourse notes shall be presumed to be exercised with nonrecourse
notes with any dividends recorded as compensation expense and interest recorded
as part of the exercise price.

     At December 31, 2004 and 2003, the outstanding loan balance due under the
Executive Loan Program was approximately $5.8 million and $9.5 million,
respectively. The loan balance, net of amounts reserved of $5.8 million and $7.6
million at December 31, 2004 and 2003, respectively, is classified in the
stockholders' deficit section of the consolidated balance sheets as notes
receivable from officers. At December 31, 2004, all executive loans are fully
reserved for.

     During the second quarter of 2003, the Company determined that certain
executives would probably be unable to repay a significant portion of the
outstanding balance due under their executive loans without a significant
recovery in the Company's stock price. Consequently, the Company recorded a
provision for loan impairment in the amount of $7.6 million, reflecting the
amount by which the carrying value of each individual's loan exceeded the
underlying estimated fair value of the assets available to repay the loan. The
Company will recognize any recoveries of amounts reserved only upon payment of
the loans. The notes are full recourse loans, and the Company intends to pursue
collection of all amounts when due. In addition to the factors noted above,
additional considerations in determining whether a reserve was necessary
included the delisting of the Company's common stock from the NYSE in the second
quarter and the continued uncertainty of an economic recovery in the markets
served by the Company.

     Commencing in 2001 with the effects of the economic slowdown and continuing
through 2004, we implemented a number of cost reduction initiatives to more
closely align our cost structure with the current business environment. In 2004,
2003 (as restated) and 2002 (as restated), operating costs, as reported in the
consolidated statement of operations, were reduced by $1.3 million, $39.7
million and $96.9 million, respectively. Specific actions taken are as follows:

     - Reduced staffing levels by approximately 1,000 positions through
       terminations and attrition;

     - Shut down or consolidated more than 30 facilities worldwide;

     - Reduced benefit costs by increasing employee contributions for health
       care;

     - Froze the benefits of the Company's defined benefit pension plan and
       supplemental executive retirement plan;

     - Suspended the Company match for our defined contribution plan;

     - Eliminated unprofitable properties;

     - Restructured various under-performing events by either eliminating these
       events or by co-locating them with other events and realigning management
       structures;

     - Sold non-core and non-strategic properties;

     - Reduced the production cost of various under-performing magazines through
       process improvements, automation of pre-press work, new printing
       contracts and selective reduction in frequency and circulation levels;

                                        39
<PAGE>

     - Commenced a plan to centralize all information technology and accounting
       services; and

     - Effectively outsourced various corporate and divisional functions.

     The Company is actively attempting to sublease all vacant facilities. For
facilities that the Company no longer occupies and which have not yet been
subleased, management makes assumptions to estimate sublease income, including
the number of years a property will be subleased, square footage, market trends,
property location and the price per square foot based on discussions with
realtors and/or parties that have shown interest in the space. The Company
records estimated sublease income as a credit to restructuring and other charges
in the consolidated statements of operations.

     Personnel costs include payments for severance, benefits and outplacement
services.

     For a more detailed discussion of activity under our restructuring plans,
including adjustments, see Note 16 -- Business Restructuring Charges, in the
notes to consolidated financial statements included herein.

2004 RESTRUCTURING CHARGES

     In 2004, the Company restructured its operations by flattening its
organizational structure as well as implementing other cost-saving strategies,
recording restructuring charges of $5.2 million. The following sets forth
details concerning the principal components of this charge:

     - Personnel costs of $4.7 million are associated with the elimination of 68
       positions, including several executive positions, primarily in the United
       States. Approximately 93% of the eliminated positions are in the United
       States, with the remainder primarily in the United Kingdom. As of
       December 31, 2004, the elimination of 67 positions and payments of $4.0
       million had been completed.

     - Office closure costs of $0.1 million relate primarily to the closure of a
       warehouse in Colorado.

     - Other exit costs of $0.4 million relate primarily to the cancellation of
       an agreement with a former employee to provide trade show and conference
       services to selected Penton events.

2003 RESTRUCTURING CHARGES

     In order to meet continued revenue challenges in 2003, the Company recorded
restructuring charges of $4.7 million. The following sets forth detail
concerning the principal components of this charge:

     - Personnel costs of $2.7 million (as restated) are associated with the
       elimination of 85 positions, of which 79 position eliminations and
       payments of $1.1 million were completed by year end 2003 with the
       remainder completed in 2004. Approximately 91% of the positions
       eliminated are in the United States, with most of the remaining positions
       in the United Kingdom.

     - Office closure costs of $3.8 million relate primarily to the closure of
       one floor at the Company's corporate headquarters and the partial closure
       of one additional facility. This charge was offset by $2.3 million of
       estimated sublease income related to these facilities.

     - The charge for other exit costs of $0.7 million relates primarily to
       equipment leases at closed facilities, cancellations of certain contracts
       and broker commissions.

     Included in restructuring and other charges in 2003 are approximately $0.6
million related to our 401(k) plan for employees who had rescissionary rights
and $0.8 million related to legal fees written off related to the Alidina suit.

2002 RESTRUCTURING CHARGES

     During 2002, we recorded restructuring charges of $16.4 million ($1.0
million of which is classified as discontinued operations). The following sets
forth additional detail concerning the principal components of this charge:

     - Personnel costs of $10.3 million were associated with the elimination of
       over 316 positions. Approximately 93% of the positions eliminated were in
       the United States, with most of the remaining positions in the United
       Kingdom.

     - Office closure costs of $5.1 million related to nine offices primarily in
       the United States. These amounts were offset by approximately $1.7
       million related to two facilities that were subleased in 2002.
       Adjustments of $1.2 million primarily relate to escalation provisions,
       which had not been taken into consideration when the original 2002
       liability was recorded.

     - Other exit costs of $1.6 million include contractual obligations
       associated with cancellation of certain trade show venues, hotel
       contracts and service agreements.

2001 RESTRUCTURING CHARGES

     During 2001, we recorded restructuring charges of $19.8 million. The
following sets forth additional detail concerning the principal components of
this charge:

     - Personnel costs of $6.8 million were associated with the elimination of
       over 400 positions. The elimination of all positions and related payments
       were completed in 2003. Approximately 84% of the positions eliminated
       were in the United States, with most of the remaining positions in the
       United Kingdom and Germany.

     - Office closure costs of $8.7 million related to the closure of more than
       20 offices worldwide. These lease obligations continue through 2013.

     Other exit costs of $4.4 million include the write-off of capitalized
software development costs associated with the discontinuance of the industry
exchange component of New Hope Natural Media's Healthwell.com. In the third
quarter of 2001, we determined that some first-quarter restructuring initiatives
would not require the level of spending that had been originally estimated and
approximately $1.0 million was reversed.

</Table>

     At December 31, 2004, the Company had an accrued restructuring balance of
$8.7 million. We expect to make cash payments in 2005 of approximately $3.3
million, comprised of $0.7 million for employee separation costs, $2.2 million
for lease obligations and $0.4 million for other contractual obligations. The
balance of severance costs will be paid through 2007. We expect to pay the
balance of facility costs, primarily long-term leases, through the end of the
respective lease terms, which extend through 2013. Amounts due within one year
of approximately $2.7 million and $3.7 million at December 31, 2004 and December
31, 2003, respectively, are classified in other accrued expenses on the
consolidated balance sheets. Amounts due after one year of approximately $6.0
million and $7.6 million at December 31, 2004 and December 31, 2003,
respectively, are included in other non-current liabilities on the consolidated
balance sheets.

     The Company expects to realize sufficient savings from its 2004
restructuring efforts to recover the employee termination costs by July 31,
2005. Savings from terminations of contracts and lease costs will be realized
over the estimated lives of the contracts or leases.

LOSS ON SALE OF PROPERTIES

     In December 2004, the Company completed the sale of 70% of its interest in
PM Germany for a loss on sale of $0.9 million. At December 31, 2004, the Company
retains a 15% interest in PM Germany, which is accounted for using the cost
method, as the Company does not exercise significant influence. See Note 3 --
Disposals, in the notes to consolidated financial statements included herein.

     In 2002, we recognized a $0.9 million loss from the sale of four properties
in December 2002, including Streaming Media, Boardwatch and ISPCON, which were
part of our Technology segment, and A/E/C, which was part of our Industry
segment.

</Table>

     The decrease in depreciation and amortization for 2004 compared to 2003 is
due to lower amortization expense related to intangible assets of properties
sold in January 2003, as well as the write-off of approximately $1.9 million and
$6.2 million of intangibles in the third quarter of 2004 and 2003 (as restated),
respectively.

     The decrease in depreciation and amortization for 2003 compared to 2002 is
due to lower amortization expense related to intangible assets of properties
sold in December 2002 and January 2003, as well as the write-off of
approximately $6.2 million and $20.0 million of intangibles in the third quarter
of 2003 (as restated) and 2002, respectively.

OTHER INCOME (EXPENSE)

     Other income (expense) consists of the following:

</Table>

     Interest expense for 2004 does not include any unusual or one-time items.
Included in interest expense in 2003 is approximately $0.9 million related to
the write-off of unamortized financing fees associated with the commitment
reduction of our credit facility revolver in January 2003 from $40.0 million to
$20.1 million. Also included in interest expense in 2003 is approximately $1.0
million related to the write-off of unamortized financing fees associated with
the replacement of our senior secured credit facility in August 2003 with a new
four-year loan agreement (see Item 1 Business -- Recent Developments and Note
7 -- Debt). Included in interest expense in 2002 is approximately $0.7 million
related to the write-off of unamortized financing fees associated with the
commitment reduction of our credit facility revolver from $185.0 million to
$40.0 million in March 2002 and approximately $1.4 million related to hedging
activities. The increase in interest expense comparing 2003 and 2002 also
reflects the higher weighted-average interest rate.

     Significant items included in other net, are as follows:

     - In January 2002, Penton sold its remaining 11.8% ownership interest in
       Jupitermedia Corporation (formerly known as INT Media Group, Inc.) for
       $5.8 million and recognized a $1.5 million gain from its sale.

     - In March 2002, we purchased $10.0 million face value of our Subordinated
       Notes at prevailing market prices, resulting in a gain of $1.4 million.
       This gain was offset by the write-off of unamortized deferred financing
       costs of approximately $1.1 million associated with the payoff of our
       term loan A and term loan B facilities, which also occurred in March
       2002.

TAXES

     In 2004 and 2002 (as restated), the Company recorded a benefit for income
taxes of $0.1 million and $30.4 million, respectively. The Company recorded a
provision for income taxes of $6.8 million in 2003 (as restated). The Company
recorded valuation allowances to offset their respective annual income tax
benefits from operations as well as the amount by which their deferred tax
assets exceeded their deferred tax liabilities, excluding the deferred tax
liability related to indefinite-lived intangibles as of 2004, 2003, and 2002.
The effective tax rates for 2004 and 2003 were a benefit of 0.1% and a provision
of 7.8%, respectively. The change in the effective tax rate for 2004 is due to
the Company realizing a tax benefit related to the reversal of approximately
$2.9 million of contingent liabilities for which the statutes of limitations
have expired.
                                        43
<PAGE>

     The effective tax rates for 2003 and 2002 were a provision of 7.8% and a
benefit of 10.7%, respectively. The change in the effective tax rate for 2003 is
due to the net operating loss available for carryforward being offset by a
valuation allowance for the Company's net deferred tax assets and net operating
loss carryforwards not expected to be utilized. The difference in the effective
tax rate between the periods is due to the establishment of the valuation
allowance in the third quarter of 2002.

     The calculation of our tax liabilities involves dealing with uncertainties
in the application of complex tax regulations. We recognize liabilities for
anticipated tax audit issues based on our estimate of whether, and the extent to
which, additional taxes will be due. If we ultimately determine that payment of
these amounts is unnecessary, we reverse the liability and recognize a tax
benefit during the period in which we determine that the liability is no longer
necessary. We also recognize tax benefits to the extent that it is probable that
our positions will be sustained when challenged by the taxing authorities. As of
December 31, 2004 we had not recognized tax benefits of approximately $2.2
million relating to various state tax positions. Should the ultimate outcome be
unfavorable, we would be required to make a cash payment for all tax reductions
claimed as of that date.

     Discontinued operations for all periods presented include the results of PM
Australia, which was sold in December 2002, and the results of PTS, which was
sold in January 2003. PM Australia was part of our Technology segment, and PTS
was part of our Industry segment.

     The $0.7 million of income recognized for 2003 was due primarily to a gain
of approximately $1.4 million associated with the sale of PTS, offset by one
month of operations for PTS and settlement costs for certain pending lawsuits
related to PM Australia. The loss from discontinued operations in 2002 of $3.3
million is due primarily to PTS where revenues decreased from $12.7 million in
2001 to $8.7 million in 2002. The revenue decrease was due primarily to the
significant economic slowdown, which started in 2001, was exacerbated by the
events of September 11, 2001, and continued through all of 2002. The loss from
discontinued operations in 2002 also included $1.0 million related to
restructuring charges and $0.6 million related to the loss from the sale of PM
Australia in December 2002.

SEGMENTS

     As of July 2004, Mr. Nussbaum is Penton's chief operating decision maker.
Mr. Nussbaum and the executive team assess and manage the Company's operations
differently than the prior management team, resulting in a change in the
Company's reportable segments effective in the third quarter of 2004. As a
result of this change in reportable segments, all prior periods have been recast
to conform with the new segment format.

     The Company's newly designated segments include: Industry, Technology,
Lifestyle, Retail and International. The results of these newly established
segments will, consistent with past practice, be regularly reviewed by the
Company's chief operating decision maker and the executive team to determine how
resources will be allocated to each segment and to assess the performance of
each segment. The segments derive their revenues from publications, trade shows
and conferences, and online media products.

     The executive management team evaluates performance of the segments based
on revenues and adjusted segment EBITDA. As such, in the analysis that follows,
we have used adjusted segment EBITDA, which we define as net income (loss)
before interest, taxes, depreciation and amortization, non-cash compensation,
executive separation costs, impairment of assets, restructuring charges,
provision for loan impairment, (gain) loss on sale of properties, discontinued
operations, general and administrative costs, and other non-operating items.
General and administrative costs include functions such as finance, accounting,
human

                                        44
<PAGE>

resources and information systems, which cannot reasonably be allocated to each
segment. See Note 18 - Segment Information, in the notes to consolidated
financial statements included herein, for a reconciliation of total adjusted
segment EBITDA to loss from continuing operations before income taxes and
cumulative effect of accounting change.

     Financial information by segment for 2004, 2003 and 2002, adjusted for
discontinued operations, is summarized as follows (in thousands):

INDUSTRY

     Our Industry segment, which represented 35.2%, 36.5% and 35.0% of total
Company revenues for 2004, 2003 and 2002, respectively, serves customers in the
manufacturing, design/engineering, mechanical systems/construction, and
government/compliance industries. For the years ended December 31, 2004, 2003
and 2002, respectively, 92.7%, 94.8% and 93.6% of this segment's revenues were
generated from publications, 2.8%, 2.4% and 4.3% from trade shows and
conferences, and 4.5%, 2.8% and 2.1% from online media and ancillary sources.

     As part of our product portfolio restructuring initiative in 2002, the
Company completed the sale of its A/E/C trade shows in December 2002 and its PTS
trade shows in January 2003, both of which were part of our Industry segment.
PTS was included as a component of discontinued operations in the accompanying
consolidated statements of operations, while A/E/C did not qualify for
discontinued operations treatment. We continually respond to opportunities in
the Industry markets we serve by developing new products that serve our
customers' changing information and marketing needs. We expect to introduce new
products in 2005.

2004 vs. 2003

     Revenues for this segment decreased $0.5 million, or 0.7%, from $75.2
million for the year ended December 31, 2003 to $74.7 million for the same
period in 2004. The decrease was due primarily to lower publication revenues of
$2.1 million partially offset by improved online media revenues of $1.3 million
and an increase in trade show and conference revenues of $0.3 million. Lower
publishing revenues were due primarily to lower advertising revenues from our
government/compliance group. The increase in online media revenues was primarily
from year-on-year improvements in our manufacturing, government/compliance and
design/engineering Web sites. The IndustryWeek Web site in our manufacturing
unit increased by 77.1% when comparing the year ended December 31, 2003 to the
same period in 2004. The increase in trade show and conferences revenues was
attributed to our Comfortech HVAC conference, which showed a 25.9% year-on-year
revenue increase.

     Adjusted segment EBITDA for our Industry portfolio increased $1.4 million,
or 7.5%, from $18.9 million for the year ended December 31, 2003 to $20.4
million for the same period in 2004. This increase is due to our online media
products, which increased by $1.0 million, and our trade shows and conferences,
which increased $0.6 million. These increases were partially offset by a
decrease of $0.2 million in publishing. The increase in adjusted segment EBITDA
margins was due primarily to cost reduction efforts.

                                        45
<PAGE>

2003 vs. 2002

     Revenues for this segment decreased $7.0 million, or 8.5%, from $82.2
million in 2002 to $75.2 million in 2003. The decrease was due primarily to
lower revenues from publications of $5.5 million and lower revenues from trade
shows and conferences of $1.8 million. Online media revenues increased $0.3
million from $1.8 million in 2002 to $2.1 million in 2003. Print advertising in
our design/engineering and government portfolios contributed most significantly
to the declines in publishing revenues in 2003; these portfolios accounted for
approximately $4.2 million of the decrease. The decrease in trade show and
conference revenues was due primarily to the loss of approximately $1.7 million
in revenues that were associated with the A/E/C trade shows, which were sold in
December 2002.

     Adjusted segment EBITDA for our Industry portfolio decreased $1.7 million,
or 8.0%, from $20.6 million in 2002 to $18.9 million in 2003. Industry
publications decreased $2.0 million, while trade shows and conferences decreased
$0.1 million. These decreases were partially offset by an increase of $0.4
million in the segment's online media portfolio. The improvement in adjusted
segment EBITDA margins was due primarily to the improvement of online media.

TECHNOLOGY

     Our Technology segment, which represented 29.4%, 30.0% and 34.9% of total
Company revenues in 2004, 2003 (as restated) and 2002, respectively, serves
customers in the business technology, enterprise information technology,
electronics, and aviation markets. For the years ended December 31, 2004, 2003
(as restated) and 2002, respectively, 63.5%, 71.1% and 68.2% of this segment's
revenues were generated from publications, 16.6%, 12.5% and 19.2% from trade
shows and conferences, and 19.9%, 16.4% and 12.6% from online media and
ancillary sources.

     As part of our product portfolio restructuring initiative in 2002, the
Company completed the sale of three properties and discontinued one property in
this segment. These properties include Streaming Media, Boardwatch, ISPCON and
PM Australia. PM Australia was included as a component of discontinued
operations in the accompanying consolidated statements of operations, while
Streaming Media, Boardwatch and ISPCON did not qualify for discontinued
operations treatment. The elimination of these properties improved the adjusted
EBITDA of our Technology segment in 2003. We are continually looking for
opportunities in the Technology segment to develop new products.

2004 vs. 2003

     Revenues for this segment increased $0.6 million, or 1.0%, from $61.8
million for the year ended December 31, 2003 (as restated) to $62.4 million for
the same period in 2004. The increase was due primarily to higher trade show and
conference revenues of $2.7 million and higher online media revenues of $2.3
million, offset by a decrease in publishing revenues of $4.4 million. The
increase in trade show and conference revenues was due primarily to an increase
of $1.4 million or 66.5% in Windows IT Pro roadshow revenues in 2004 compared
with 2003. The fall ASP/VS Connections and SQL server conferences, which are
both IT Media events, contributed a $1.5 million increase over 2003 revenues.
The increase in online media revenues was due to year-over-year improvements in
Windows online custom media, the Windows Web sites, Business Finance webcasts
and eMedia in our Electronics OEM group. The decrease in the segment's
publishing revenues was due partially to a decline in our Windows IT Pro and
e-Pro magazines of $3.3 million, and the elimination of over $1.1 million in
revenues related to our Internet World magazine. Internet World was discontinued
in 2003. e-Pro was discontinued in May 2004.

     Adjusted segment EBITDA for our Technology portfolio increased $3.4
million, or 37.3%, from $8.9 million for the year ended December 31, 2003 (as
restated) to $12.3 million for the same period in 2004. The increase was
attributable to online media of $2.0 million and trade shows and conferences of
$2.1 million. Overhead costs for the segment also improved by $0.5 million.
These improvements were partially offset by a decline of $1.2 million in the
segment's publications. The increase in adjusted segment EBITDA margins was due
to cost reduction efforts taken.

2003 vs. 2002

     Revenues for this segment decreased $20.1 million, or 24.5%, from $81.9
million in 2002 (as restated) to $61.8 million in 2003 (as restated). The
decrease was due primarily to lower revenues from publications of $11.8 million
and lower revenues from trade shows and conferences of $8.1 million. Consistent
with most b-to-b technology media, Penton's products suffered through a third
full year of difficult conditions in 2003. Our print media serving the
enterprise information technology and electronics OEM portfolios experienced the
greatest market challenges. Online media revenues decreased $0.2 million from
$10.3 million in 2002 to $10.1 million in 2003.

     Adjusted segment EBITDA for our Technology portfolio increased $4.5
million, or 103.6%, from $4.4 million in 2002 (as restated) to $8.9 million in
2003 (as restated). Trade shows and conferences accounted for $3.3 million of
the increase, while general and administrative and facility costs improved by
$1.9 million. These improvements were partially offset by a decrease in the
segment's publications of $0.5 million and a decrease in online media of $0.2
million. The significant adjusted segment EBITDA increase for trade shows and
conferences and the lower general and administrative and facility costs were due
primarily to our restructuring activities taken in 2002 and 2003.

LIFESTYLE

     Our Lifestyle segment, which represented 17.0%, 15.4% and 12.9% of total
Company revenues in 2004, 2003 and 2002, respectively, serves customers in our
natural products industry sector. Products in this sector serve the natural and
organic products and nutraceuticals markets, including producers of raw
materials, manufacturers, distributors and retailers. For the years ended
December 31, 2004, 2003, and 2002, respectively, 33.4%, 34.8% and 36.4% of this
segment's revenues were generated from publications and 66.6%, 65.2% and 63.6%
from trade shows and conferences.

2004 vs. 2003

     Revenues for this segment increased $4.5 million, or 14.1%, from $31.7
million for the year ended December 31, 2003 to $36.2 million for the same
period in 2004. Trade shows and conferences accounted for $3.4 million of the
increase and publishing revenues accounted for $1.0 million. The increase in our
Lifestyle segment was due primarily to the success of the Natural Products Expo
West and East events, which were held in the first and fourth quarter of 2004,
respectively. Natural Products Expo West experienced a 20.2% year-over-year
increase in revenues and the East event had a 15.0% year-over-year improvement
in revenues. Publishing revenues in the segment also grew, with improvements
experienced by Delicious Living and The Natural Foods Merchandiser magazines.

     Adjusted segment EBITDA for the Lifestyle segment increased $2.6 million,
or 22.2%, from $11.6 million for the year ended December 31, 2003 to $14.1
million for the same period in 2004. Trade shows and conferences accounted for
$2.0 million and publications accounted for $1.4 million of the increase, offset
by $0.8 million higher overhead costs.

2003 vs. 2002

     Revenues for this segment increased $1.5 million in 2003 when compared with
2002. The Natural Products Expo East and the Natural Products Expo West trade
shows accounted for all of this increase as publication revenues in 2003 were
flat with 2002.

     Adjusted segment EBITDA for the Lifestyle segment increased $1.1 million to
$11.6 million in 2003, from $10.5 million in 2002. Trade shows and conferences
increased $1.0 million, from $10.9 million in 2002 to $11.9 million in 2003.
Publications for this segment were flat when compared with 2002. Adjusted
segment EBITDA margins improved from 34.8% in 2002 to 36.4% in 2003, due
primarily to stable revenues and cost reduction measures taken in 2003.

RETAIL

     Our Retail segment, which represented 9.8%, 9.7% and 8.3% of total Company
revenues for 2004, 2003 and 2002, respectively, serves customers in the
food/retail and hospitality sectors. Revenues for this segment are primarily
generated from publishing sales, which comprised approximately 92.4%, 90.0% and
91.1% of total 2004, 2003 and 2002 revenues, respectively. Trade shows and
conferences make up a majority of the remaining revenues for this segment, while
online media revenues generated $0.3 million, $0.4 million and $0.4 million in
revenues in 2004, 2003 and 2002, respectively.

2004 vs. 2003

     Revenues for this segment increased $1.0 million, or 5.0%, from $19.9
million for the year ended December 31, 2003 to $20.9 million for the same
period in 2004. The increase was due primarily to year-over-year revenue
improvements in our Restaurant Hospitality and Lodging Hospitality magazines
offset by lower year-on-year revenues from our Convenience Store Decisions
magazine, slightly lower trade show and conference revenues, and a modest
decline in online media revenues.

     Adjusted segment EBITDA for the Retail segment remained flat for the year
ended December 31, 2003 compared with the same period in 2004. Although EBITDA
for publications increased by $1.2 million due to revenue increases noted above,
these improvements were offset by a slight decrease from trade shows and
conferences and higher overhead costs.

2003 vs. 2002

     Revenues for this segment increased $0.4 million, or 1.9%, from $19.6
million in 2002, to $19.9 million in 2003. This increase was due primarily to an
increase in trade show and conference revenues of $0.3 million and an increase
in publishing revenues of $0.1 million. Online media revenues remained flat.

     Adjusted segment EBITDA for the Retail segment increased $0.5 million, or
10.7%, from $4.9 million in 2002 to $5.4 million in 2003. Publications and trade
shows and conferences accounted for $0.2 million and $0.3 million of the
increase, respectively. Online media remained flat. Improvements across the
board were due to higher revenues and cost reduction measures taken, including
staff reductions, office closings, and process improvements.

INTERNATIONAL

     Our International segment represented 8.6%, 8.4% and 8.9% of total Company
revenues for 2004, 2003 and 2002, respectively, serves customers in the European
markets. For the year ended December 31, 2004 and 2003, respectively, 18.0%,
24.4% and 15.7% of this segment's revenues were generated from publications,
74.0%, 68.4% and 83.0% from trade shows and conferences, and 8.0%, 7.2% and 1.3%
from online media products.

2004 vs. 2003

     Revenues for this segment increased $1.0 million, or 5.8%, from $17.3
million for the year ended December 31, 2003 to $18.3 million for the same
period in 2004. The increase was due primarily to an improvement in trade show
and conference revenues of $1.7 million and an increase in online media revenues
of $0.2 million, offset by a decrease in publishing revenues of $0.9 million.
The increase in trade show and conference revenues was due primarily to our
biannual Motion & Control event, which was held in 2004, and the year-on-year
improvement of trade shows and conferences produced in Germany. The increase in
online media revenues was due primarily to the launch of our Service Management
Online 365 virtual event in 2004. The decrease in publishing revenues was due
primarily to our German operations, which discontinued a number of magazines in
2004.

     Adjusted segment EBITDA for the International segment decreased $0.6
million, or 83.2%, from $0.7 million for the year ended December 31, 2003 to
$0.1 million for the same period in 2004. The decrease was due primarily to
year-over-year performance declines of European trade shows and conferences.
This
                                        48
<PAGE>

trend has continued into the first quarter of 2005. The Company may be required
to record additional impairment charges in addition to those already taken in
2004, if this trend continues.

2003 vs. 2002

     Revenues for this segment decreased $3.7 million, or 17.6%, from $21.0
million for the year ended December 31, 2002 to $17.3 million for the same
period in 2003. The decrease was due primarily to a decline in trade show and
conferences revenues of $5.6 million. These decreases were partially offset by
an increase in online media revenues of $1.0 million and an increase in
publishing revenues of $0.9 million. The decrease in trade show and conferences
revenues was due primarily to our Internet World Berlin trade show and the sale
of our ISPCON London trade show. Also contributing to the decrease was our
biannual Motion & Control event, which was held in 2002 and not in 2003. The
increase in online media revenues is due primarily to the launch of our iSeries
Online in 2003. The increase in publishing was due primarily to our German
operations.

     Adjusted segment EBITDA for the International segment increased $0.3
million, or 59.7%, from $0.4 million for the year ended December 31, 2002 to
$0.7 million for the same period in 2003. The increase was due primarily to the
increase in online products and overhead cost reductions.

LIQUIDITY AND CAPITAL RESOURCES

Current Liquidity

     At December 31, 2004, our principal sources of liquidity are our existing
cash reserves of $7.7 million and available borrowing capacity under our credit
facility of $39.7 million.

     In February 2005, we repurchased $5.5 million of our 10 3/8% senior
subordinated notes for $3.9 million, including $0.1 million of accrued interest,
using excess cash on hand. The notes were purchased in the open market and were
trading at 69% of their par value at the time of purchase. The repurchase is
expected to reduce interest costs by approximately $0.6 million annually. We may
from time to time seek to retire additional outstanding debt through cash
purchases on the open market, privately negotiated transactions or otherwise.
Such repurchases, if any, will depend on the prevailing market conditions, our
liquidity requirements, contractual restrictions and other factors. The amounts
involved may be material.

     Our cash requirements for the next 12 months are primarily to fund:

     - operations;

     - debt service costs, which are expected to be approximately $36.3 million
       in 2005;

     - capital expenditures of approximately $1.5 million;

     - payments related to our business restructuring initiatives of
       approximately $3.3 million, comprising $0.7 million for employee
       separation costs, $2.2 million for lease obligations and $0.4 million for
       other contractual obligations; and

     - contributions totaling $1.6 million to our employees' Retirement and
       Savings Plan accounts. No cash contributions are expected to be made in
       2005 related to our defined benefit pension plan.

     We have no principal repayment requirements until maturity of our Secured
Notes in October 2007. In addition, we have no bank debt and no maintenance
covenants on our existing bond debt.

     We believe that our existing sources of liquidity, along with revenues
expected to be generated from operations, will be sufficient to fund our
operations, anticipated capital expenditures, working capital, and other
financing requirements. However, we cannot assure you that this will be the
case, and if we continue to incur operating losses and negative cash flows in
the future, we may need to reduce further our operating costs or obtain
alternate sources of financing, or both, to remain viable. Our ability to meet
cash operating requirements depends upon our future performance, which is
subject to general economic conditions and to financial, competitive, business,
and other factors. The Company's ability to return to sustained profitability at
acceptable levels will depend on a number of risk factors, many of which are
largely beyond the Company's

                                        49
<PAGE>

control. Some of the risk factors that have had and/or may have a negative
impact on the Company's business and financial results are discussed in "Risk
Factors" under Item 1 of this document. If we are unable to meet our debt
obligations or fund our other liquidity needs, particularly if our revenues
deteriorate, we may be required to raise additional capital through financing
arrangements or the issuance of private or public debt or equity securities. We
cannot assure you that such additional financing will be available at acceptable
terms. In addition, the terms of our convertible preferred stock and warrants
issued, including the conversion price, dividend and liquidation adjustment
provisions could result in substantial dilution to common stockholders. The
redemption price premiums and board representation rights could negatively
impact our ability to access the equity markets in the future.

     The Company has implemented, and continues to implement, various
cost-cutting programs and cash conservation plans, which involve the limitation
of capital expenditures and the control of working capital.

     Our loan and security agreement contains several provisions, which could
have a significant impact as to the classification as well as the acceleration
of payments for any borrowings outstanding under the agreement, including the
following: (i) the obligation of the lender to provide any advances under the
loan agreement is subject to no material adverse change events; (ii) reserves
may be established against the borrowing base for sums that the Company is
required to pay, such as taxes and assessments and other types of required
payments, and has failed to pay; (iii) in the event of a default under the loan
agreement, the lender has the right to direct all cash that is deposited in the
Company's lock boxes to be sent to the lender to pay down outstanding
borrowings; (iv) the loan agreement establishes cross-defaults to the Company's
other indebtedness (such as the Secured Notes and Subordinated Notes) such that
a default under the loan agreement could cause a default under the notes
agreements and vice versa; however, default triggering thresholds are different
in the loan agreement and the notes; (v) if the Company is in default of any
material agreement to which it is a party and the counter-party to that
agreement has the right to terminate such agreement as a result of the default,
this constitutes an event of default under the loan agreement. Under the loan
agreement, the lenders reserve the right to deem the notes in default, and in
those limited circumstances, could accelerate payment of the outstanding loan
balances should the Company undergo a material adverse event. Even though the
criteria defining a material adverse event are subjective, the Company does not
believe that the exercise of the lenders' right is probable nor does it foresee
any material adverse events in 2005. In addition, the Company believes that the
11 7/8% senior secured and 10 3/8% senior subordinated note agreements are
long-term in nature. Accordingly, the Company continues to classify its notes as
long term. At December 31, 2004, the Company was in compliance with all of the
above provisions.

Analysis of Cash Flows

     Penton's cash and cash equivalents at December 31, 2004, was $7.7 million
compared with $29.6 million at December 31, 2003. Cash used by operating
activities was $20.5 million for the year ended December 31, 2004, compared with
cash provided by operations of $27.7 million for the year ended December 31,
2003. Operating cash flows for the year ended December 31, 2004, reflected a net
loss of $67.2 million and a net decrease in working capital items of $14.4
million, partially offset by non-cash charges (primarily impairment of asset
charges and depreciation and amortization) of approximately $61.1 million.
Operating cash flows for the year ended December 31, 2003, reflected a net loss
of $93.1 million, offset by a net increase in working capital items (due
primarily to a tax refund of $52.7 million) of approximately $42.7 million and
non-cash charges (primarily impairment of asset charges, depreciation and
amortization, provision for loan impairment and deferred income tax) of
approximately $78.2 million. Operating cash flows for the year ended December
31, 2002, reflected a net loss of $296.5 million, which was offset by non-cash
charges (primarily impairment of asset charges, cumulative effect of accounting
change, restructuring charges and depreciation and amortization) of
approximately $328.7 million.

     The decrease in cash from operating activities in 2004 compared to 2003 was
due primarily to the tax refund of $52.7 million received in January 2003 and
the absence of such benefit in 2004. Excluding this refund from 2003 operating
activities, the cash used from operations in 2004 actually improved by nearly
$4.6 million. Also contributing to the decrease in cash from operating
activities in 2004 compared to 2003 was the increase in accounts receivable, net
and the decrease in unearned income, both due to timing of when
                                        50
<PAGE>

trade shows are held and when deposits are due and collected. The increase in
operating cash flows for 2003 compared with 2002 was due primarily to the tax
refund received in January 2003 of approximately $52.7 million, compared with a
tax refund of $12.2 million received in February 2002 and the increase in
unearned income due primarily to the timing of exhibition deposit payments and
the timing of when trade shows are held.

     Investing activities used $1.5 million of cash in 2004. The use of $2.3
million for capital expenditures was partially offset by cash proceeds of $0.8
million from the sale of 70% of our interest in PM Germany. Capital expenditures
in 2004 were primarily for computer hardware and software. Investing activities
provided $1.5 million of cash in 2003 (as restated) due primarily to proceeds
from the sale of PTS in January 2003 of $3.2 million and repayment of a note
receivable of $1.6 million. These proceeds were partially offset by capital
expenditures of $3.3 million. Capital expenditures in 2003 were primarily for
desktop computers and management information systems. Investing activities used
$2.7 million of cash in 2002 (as restated). Capital expenditures of
approximately $3.9 million and earnout payments of approximately $5.5 million
were offset by proceeds of $5.8 million from the sale of approximately 3.0
million shares of Jupitermedia Corporation common stock, as well as proceeds
received from the sale of certain properties in December 2002.

     Financing activities provided $0.1 million of cash in 2004 primarily as a
result of an increase in cash overdrafts partially offset by an increase in
restricted cash. Financing activities used $6.5 million of cash for 2003 (as
restated) primarily for the repayment of $4.5 million of our senior secured
credit facility, the payment of financing fees of approximately $2.0 million and
the payoff of a note payable of $0.4 million. These uses were partially offset
by $0.7 million of restricted cash and proceeds of approximately $0.3 million
from the partial repayment of an officer's loan. Financing activities provided
$6.0 million of cash in 2002 (as restated), due to the issuance of our Secured
Notes, the sale of 50,000 shares of Series B Preferred stock, amounts drawn
under our revolving credit facility, and proceeds received from the repayment of
executive loans. These proceeds were primarily offset by the pay down of our
senior secured credit facility; the purchase of $10.0 million face value of our
Subordinated Notes at prevailing market prices; the payment of financing fees
associated with the amendment to our senior credit facility and the issuance of
our Secured Notes; and the payment of the short-term portion of our note
payable.

DEBT SERVICE

     At December 31, 2004, we had total indebtedness of $329.1 million. Our
principal obligations are described below.

Subordinated Notes:

     In June 2001, we issued $185.0 million of 10 3/8% Subordinated Notes due
June 2011. Interest on the notes is payable semiannually, on June 15 and
December 15. The Subordinated Notes are fully and unconditionally, jointly and
severally guaranteed, on a senior subordinated basis, by the assets of our
domestic subsidiaries, which are 100% owned by the Company, and may be redeemed,
in whole or in part, on or after June 15, 2006. In addition, we may redeem up to
35% of the aggregate principal amount of the Subordinated Notes before June 15,
2004 with the proceeds of certain equity offerings. The Subordinated Notes were
offered at a discount of $4.2 million. This discount is being amortized using
the interest method over the term of the Subordinated Notes. Costs representing
underwriting fees and other professional fees of approximately $1.7 million are
being amortized over the term of the Subordinated Notes. The Subordinated Notes
are our unsecured senior subordinated obligations, subordinated in right of
payment to all existing and future senior indebtedness, including the loan
agreement and the Secured Notes discussed below.

     The Subordinated Notes are jointly and severally irrevocably and
unconditionally guaranteed on a senior subordinated basis by each of our present
and future domestic subsidiaries. The indenture governing the Subordinated Notes
contains covenants that, among other things, restrict our and our subsidiaries'
ability to borrow money; pay dividends on or repurchase capital stock; make
certain investments; enter into agreements that restrict our subsidiaries from
paying dividends or making other distributions, making loans or otherwise
transferring assets to us or to any other subsidiaries; create liens on assets;
engage in transactions with

                                        51
<PAGE>

affiliates; sell assets, including capital stock of our subsidiaries; and merge,
consolidate or sell all or substantially all of our assets and the assets of our
subsidiaries. Our ability to obtain dividends from our subsidiaries is
restricted only if we are in default under our loan agreement or if we have
exceeded our limitation of additional indebtedness, as specified in the
indenture.

Secured Notes:

     In March 2002, Penton issued $157.5 million of 11 7/8% Secured Notes due in
2007. Interest is payable on the Secured Notes semiannually on April 1 and
October 1. The Secured Notes are fully and unconditionally, jointly and
severally guaranteed, on a senior basis, by all of our domestic subsidiaries,
which are 100% owned by the Company, and also the stock of certain subsidiaries.
We may redeem the Secured Notes, in whole or in part, during the periods October
1, 2005 through October 1, 2006 and thereafter at redemption prices of 105.9375%
and 100.0000% of the principal amount, respectively, together with accrued and
unpaid interest to the date of redemption. In addition, at any time prior to
October 1, 2005, upon certain public equity offerings of our common stock, up to
35% of the aggregate principal amount of the Secured Notes may be redeemed at
our option, within 90 days of such public equity offering, with cash proceeds
from the offering at a redemption price equal to 111.875% of the principal
amount, together with accrued and unpaid interest to the date of redemption.

     The Secured Notes were offered at a discount of $0.8 million, which is
being amortized, using the interest method, over the term of the Secured Notes.
Costs representing underwriting fees and other professional fees of $6.6 million
are being amortized over the term of the Secured Notes. The Secured Notes rank
senior in right to all of our senior subordinated indebtedness, including our
Subordinated Notes. The guarantees are senior secured obligations of each of our
subsidiary guarantors and rank senior in right of payment to all subordinated
indebtedness of the subsidiary guarantors, including the guarantees of our
Subordinated Notes, and equal in right of payment with all of our senior
indebtedness. The notes and guarantees are secured by a lien on substantially
all of our assets and those of our subsidiary guarantors, other than specified
excluded assets. Excluded assets consist of, among other things, the capital
stock of Duke Communications International, Inc. and Internet World Media, Inc.;
the capital stock of our foreign subsidiaries directly owned by us or the
subsidiary guarantors which exceed 65% of the outstanding capital stock or
equity interest of such foreign subsidiaries; and all of the capital stock of
our other foreign subsidiaries.

     The indenture governing the Secured Notes contain covenants that, among
other things, restrict our and our subsidiaries' ability to borrow money; pay
dividends on or repurchase capital stock; make certain investments; enter into
agreements that restrict our subsidiaries from paying dividends or other
distributions, making loans or otherwise transferring assets to us or to any
other subsidiaries; create liens on assets; engage in transactions with
affiliates; sell assets, including capital stock of our subsidiaries; and merge,
consolidate or sell all or substantially all of our assets and the assets of our
subsidiaries. Our ability to obtain dividends from our subsidiaries is
restricted only if we are in default under our loan agreement or if we have
exceeded our limitation of additional indebtedness, as specified in such
agreement.

Loan and Security Agreement:

     In August 2003, the Company entered into a four-year revolving loan and
security agreement. Pursuant to the terms of the loan and security agreement,
the Company can borrow up to the lesser of (i) $40.0 million; (ii) 2.25x the
Company's last twelve months adjusted EBITDA measured monthly through August 13,
2005 and 2.0x thereafter; (iii) 40% of the Company's last six months of
revenues; or (iv) 25% of the Company's enterprise value, as determined annually
by a third party. The revolving credit facility bears interest at LIBOR plus
5.0% subject to a LIBOR minimum of 1.5%. The Company must comply with a
quarterly financial covenant limiting the ratio of maximum bank debt to the last
twelve months adjusted EBITDA to 2.25x from June 30, 2004 through March 31, 2005
and 2.0x thereafter. The loan agreement permits the Company to sell assets of up
to $12.0 million in the aggregate during the term or $5.0 million in any single
asset sale, and complete acquisitions of up to $5.0 million per year. Included
in the loan agreement are two stand-by letters of credit of $0.1 million and
$0.2 million, respectively, required by two of the Company's facility leases.
The amounts of the letters of credit reduce the availability under the credit
facility. As of December 31, 2004, no
                                        52
<PAGE>

amounts were drawn under the stand-by letters of credit. Costs representing bank
fees and other professional fees of $1.9 million are being amortized over the
life of the loan agreement. At December 31, 2004, $39.7 million was available
under the loan agreement.

     On March 30, 2005, the Company received an extension until May 15, 2005 to
deliver its annual audited financial statements to its Lender Group. The terms
of our Loan and Security Agreement require us to provide annual audited
financial statements within 90 days of the end of our fiscal year.

     On April 1, 2005, the Company borrowed $6.0 million under the Company's
Loan and Security Agreement. The proceeds were used to pay the interest due on
April 1 under the Company's 11 7/8% senior secured notes ("Secured Notes").

Consolidated Adjusted EBITDA

     Pursuant to the terms of the loan and security agreement, the Company can
borrow up to the lesser of (i) $40.0 million; (ii) 2.25x the Company's last 12
months' Consolidated Adjusted EBITDA measured monthly through August 13, 2005
and 2.0x thereafter; (iii) 40% of the Company's last six months of revenues; or
(iv) 25% of the Company's enterprise value, as determined annually by a third
party. In addition, under our loan and security agreement, we are not permitted
to allow the ratio of outstanding indebtedness to Consolidated Adjusted EBITDA
to exceed 2.25 to 1.00 for the 12-month period ending March 31, 2005 and 2.0 to
1.00 thereafter.

     Consolidated EBITDA is a non-GAAP financial measure that is presented not
as a measure of operating results, but rather as a measure of our ability to
service debt. It should not be construed as an alternative to either income/loss
before income taxes, or cash flows from operating activities. Our inability to
borrow based on the terms of the loan and security agreement could have a
material adverse effect on our liquidity and operations. Accordingly, management
believes that the presentation of Consolidated Adjusted EBITDA will provide
investors with information needed to assess our ability to continue to have
access to funds as necessary. The following table presents a reconciliation of
EBITDA and Consolidated adjusted EBITDA to net loss (in thousands). Other
companies may calculate similarly titled measures differently than we do.

CONVERTIBLE PREFERRED STOCK

     In March 2002, we entered into an agreement with a group of investors to
sell 50,000 shares of Series B Preferred stock and warrants to purchase 1.6
million shares of our common stock for $50.0 million. We received gross proceeds
of $40.0 million from the sale of 40,000 shares of convertible preferred stock
and warrants to purchase 1,280,000 shares of our common stock on March 19, 2002
and gross proceeds of $10.0 million from the sale of 10,000 shares of
convertible preferred stock and warrants to purchase 320,000 shares of our
common stock on March 28, 2002.

     On September 13, 2004, the Company filed a Certificate of Designations
governing a new series of convertible preferred stock, $0.01 par value (the
"Series C Preferred"), with the Secretary of State for the State of Delaware.
The Series C Preferred stock was exchanged on a share-for-share basis with the
Company's Series B Convertible Preferred Stock, $0.01 par value (the "Series B
Preferred"). The Certificate

                                        54
<PAGE>

of Designations for the Series C Preferred stock is identical to the Series B
Preferred stock Certificate of Designations except that:

     - the new series allows for the sharing of the liquidation preference with
       the new Series M Preferred Stock (discussed below),

     - certain technical and correcting amendments have been made to the
       Certificate of Designations for the Series C Preferred stock, including
       fixing the formula used to calculate the "Change of Control Cap" (as
       defined in the Series C Preferred stock Certificate of Designations), and

     - certain conforming changes were made to the Series C Preferred stock
       Certificate of Designations to account for the fact that the Series C
       Preferred stock was issued in exchange for the Series B Preferred stock.

     At December 31, 2004, the amount due to the Series C Preferred
stockholders, including principal and accrued dividends, was $67.2 million. The
convertible preferred stock currently accrues dividends at the maximum rate of
10% per annum. If the Company had been sold on December 31, 2004, the Series C
Preferred stockholders would have been entitled to receive $122.5 million for
their shares. The amount the Series C Preferred stockholders would be entitled
to receive could increase significantly in the future under certain
circumstances. See Note 11 -- Mandatorily Redeemable Convertible Preferred
Stock, in the notes to consolidated financial statements included herein.

(1) There are no required debt principal payments until October 2007. Interest
    is paid semi-annually in June and December for the Subordinated Notes and
    April and October for the Secured Notes. In February 2005, the Company
    repurchased $5.5 million par value of its 10 3/8% senior subordinated notes
    for a total of $3.9 million. The notes were purchased in the open market and
    were trading at 69% of their par value at the time of purchase. As a result
    of this repurchase, future interest payments will be reduced annually by
    $0.6 million.

(2) We lease all of our facilities and certain equipment under non-cancelable
    operating leases. The leases expire at various dates through 2014 and some
    contain various provisions for rental adjustments.

(3) In December 1999, Penton entered into a print agreement with R.R. Donnelley,
    which entitles them to the exclusive right to print and produce certain
    Penton magazines through November 30, 2006. Under

                                        55
<PAGE>

    the agreement, which is non-cancelable, Penton is obligated to pay certain
    minimum amounts. These minimum amounts will be adjusted annually based on
    changes in the Consumer Price Index. In February 2005, the Company signed a
    new agreement with R.R. Donnelley, which expires in December 2011, unless a
    minimum revenue commitment of $42.0 million is not reached, at which time
    the agreement would extend until the commitment is reached.

(4) In February 2004, the Company amended its communication services agreement
    with Sprint, originally entered into in 2002, to extend the term to February
    2007. The agreement provides for annual minimum usage levels by Penton of
    $0.8 million each year.

(5) Penton made a $1.5 million cash contribution to its defined benefit pension
    plan for 2004. Based on current estimates the Company expects to make a
    contribution of approximately $1.8 million in 2007. No contributions are
    expected in 2005 or 2006. Due to the presence of significant variables,
    actual future contributions may differ materially.

     In 2004, the Company made contributions totaling $1.7 million to employees'
Retirement Savings Plan accounts. We expect to make contributions totaling $1.6
million in 2005. Contributions are made at the discretion of our Board of
Directors.

     The Company is self-insured for health and workers' compensation benefits
up to certain stop-loss limits. In 2004, the Company paid approximately $3.6
million in health and workers' compensation claims. The Company expects payments
in 2005 to range between $3.5 million and $4.0 million.

     In December 2003, the Company entered into an agreement with a former
employee to provide trade show and conference services to select Penton events.
Under the agreement, the former employee was to receive guaranteed minimum
payments of $0.7 million in 2005 unless the contract was cancelled. In December
2004, the Company terminated the agreement, which required a $0.2 million
cancellation fee. The fee will be paid in twelve equal installments throughout
2005.

OFF-BALANCE SHEET ARRANGEMENTS

     The Company has no special purpose entities or off-balance sheet debt,
other than operating leases in the ordinary course of business, which are fully
disclosed in Note 10 -- Commitments and Contingencies of the notes to the
consolidated financial statements appearing elsewhere herein.

     The Company has stand-by letters of credit of $0.1 million and $0.2
million, respectively, required by two of the Company's facility leases. At
December 31, 2004, no amounts were drawn under the stand-by letters of credit.
Letters of credit are purchased guarantees that ensure our performance or
payment to third parties in accordance with specified terms and conditions.

     Under certain agreements, indemnification provisions may require the
Company to make payments to third parties. In connection with certain facility
leases, we may be required to indemnify our lessors for certain claims. The
Company has agreed to indemnify the purchasers of several of our properties from
all claims prior to the sale. The Company will also indemnify its directors,
officers, employees and agents to the maximum extent permitted under the laws of
the State of Delaware. The duration of these indemnity provisions under the
terms of each agreement varies. The majority of indemnities do not provide for
any limitation of the maximum potential future payments we could be obligated to
make.

     In 2004, we did not make any payments under any of these indemnification
provisions or guarantees, and we have not recorded any liability for these
indemnities in the accompanying consolidated balance sheets.

RELATED PARTY TRANSACTIONS

     See Note 17 -- Related Party Transactions, in the notes to consolidated
financial statements included herein for a complete description of all related
party transactions.

FOREIGN CURRENCY

     The functional currency of our foreign operations is their local currency.
Accordingly, assets and liabilities of foreign operations are translated to U.S.
dollars at the rates of exchange 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 for the
periods presented.

SEASONALITY

     We may experience seasonal fluctuations as trade shows and conferences held
in one quarter in the current year may be held in a different quarter in future
years.

INFLATION

     The impact of inflation on our results of operations has not been
significant in recent years.

RECENT ACCOUNTING PRONOUNCEMENTS

     See Note 1 -- Description of Business and Significant Accounting Policies,
in the notes to consolidated financial statements included herein.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     Our discussion and analysis of our financial condition and results of
operations are based upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities,
revenues and expenses, and related disclosure of contingent assets and
liabilities. On an ongoing basis, we evaluate our estimates, including those
related to bad debts, intangible assets, income taxes, restructuring, pension
benefits, contingencies and litigation. We base our estimates on historical
experience and on various other assumptions that are believed to be reasonable
under the circumstances, the results of which form the basis for making
judgments about the carrying values of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

     We believe the following critical accounting policies affect our more
significant judgments and estimates used in the preparation of our consolidated
financial statements. We have discussed the application of these critical
accounting estimates with the Audit Committee of our Board of Directors.

REVENUE RECOGNITION

     Advertising revenues from Penton's trade magazines are recognized in the
month the publications are mailed. Subscription revenues are recognized over the
subscription period, typically one year. Amounts received in advance of trade
shows and conferences are deferred and recognized in the month the events are
held. Online media revenues primarily include advertising revenues such as
banner advertising, sponsorships, e-newsletters, e-books and web seminars.
Revenue is recognized in the period the obligation is fulfilled or delivered.

     When a sale involves multiple deliverables where the deliverables are
governed by more than one authoritative standard, we evaluate all deliverables
to determine whether they represent separate units of accounting based on the
following criteria:

     - whether the delivered item has value to the customer on a stand-alone
       basis;

     - whether there is objective and reliable evidence of the fair value of the
       undelivered item(s); and

     - if the contract includes a general right of return relative to the
       delivered item, delivery or performance of the undelivered item(s) is
       considered probable and is substantially in our control.

                                        57
<PAGE>

     Our determination of whether deliverables within a multiple element
arrangement can be treated separately for revenue recognition purposes involves
significant estimates and judgment, such as whether fair value can be
established on undelivered obligations and/or whether delivered elements have
standalone value to the customer. Changes in our assessment of the accounting
units in an arrangement and/or our ability to establish fair values could
significantly change the timing of revenue recognition.

COLLECTIBILITY OF ACCOUNTS RECEIVABLE

     In order to record our accounts receivable at their net realizable value,
we must assess their collectibility. A considerable amount of judgment is
required in order to make this assessment, including an analysis of historical
bad debts, a review of the aging of our receivables and the current
creditworthiness of our customers. Generally, individual credit assessments of
all current and potential customers occur prior to any credit being extended and
at regular intervals thereafter. The following factors are considered as part of
the credit assessment:

     - a customer's ability to meet and sustain its financial commitments;

     - a customer's current and projected financial condition;

     - the positive or negative effects of the current and projected industry
       outlook; and

     - the economy in general.

     After considering all of the above factors, we record an allowance for
doubtful accounts for those receivables that we feel are uncollectible. In
general, if a balance has been outstanding for 90 days, we require cash with any
future order. Balances outstanding in excess of 120 days are placed in
collections. Based on historical collections of amounts placed for collection,
we reserve 50% of all such amounts. In addition, a detailed subjective
assessment of each account placed for collection is performed and additional
reserves are recorded as needed.

     The decrease in our allowance for doubtful accounts from $4.3 million at
December 31, 2002, to $3.7 million at December 31, 2003, and to $2.8 million at
December 31, 2004 primarily reflects the general improvement in the overall
economy during those periods. It appears that our customers are feeling the
impact of this improvement as our days-sales-outstanding ratio has steadily
decreased over the period.

IMPAIRMENT OF LONG-LIVED ASSETS

     We continually monitor and review long-lived assets, including fixed
assets, goodwill and intangible assets, for impairment whenever events or
changes in circumstances indicate that the carrying amount of any such asset may
not be recoverable. Factors that could trigger an impairment test include, but
are not limited to:

     - a permanent decline in cash flows;

     - continued decreases in utilization of a long-lived asset;

     - a change in business strategy;

     - a significant adverse change in the business climate or legal factors;

     - unanticipated competition;

     - loss of key personnel;

     - the likelihood that a reporting unit or a significant portion of a
       reporting unit will be sold or disposed of; and/or

     - recognition of a goodwill impairment loss in the financial statements of
       a subsidiary that is a component of a reporting unit.

                                        58
<PAGE>

     The process involves management determining if the cash flows expected to
be generated from the use of a long-lived asset group and its eventual
disposition (undiscounted and without interest charges) are less than the
carrying amount of the asset group. If the criteria are met, the fair value is
determined using appropriate assumptions. The estimate of cash flows is based
upon, among other things, certain assumptions about expected future operating
performance, growth rates and other factors. Our estimates may differ from
actual cash flows due to, among other things, technological changes, economic
conditions, changes to our business model, or changes in our operating
performance. The determination of impairment requires significant management
judgment, including establishing asset groupings.

     Goodwill is tested annually on September 30 of each year for impairment
using the fair-value-based test prescribed by SFAS 142. The estimates and
assumptions described above (along with other factors such as discount rates)
affect the amount of impairment recognized.

     The Company completed its annual SFAS 142 impairment review at September
30, 2004, which resulted in a non-cash impairment charge of approximately $37.8
million. This goodwill impairment charge is due primarily to lower-than-expected
future cash flows in two reporting units in our Technology segment and
lower-than-expected future cash flows in our International segment.

     The Company completed its annual SFAS 142 impairment review at September
30, 2003, which resulted in a non-cash goodwill impairment charge of
approximately $37.6 million to reduce the carrying value of goodwill for two
reporting units, that are part of our Technology segment and one reporting unit,
that is part of our Retail segment.

     During the third quarter of 2002, Penton completed its initial impairment
test under SFAS 142 for January 1, 2002 and recorded a non-cash charge of $39.7
million to reduce the carrying value of goodwill for two of our seven identified
reporting units. In addition, a number of events occurred during the third
quarter that indicated an additional impairment of goodwill might exist. As a
result of these triggering events and circumstances, the Company completed an
additional SFAS 142 impairment review at September 30, 2002. This review
resulted in a non-cash impairment charge of approximately $203.3 million to
further reduce the carrying value of goodwill for the two reporting units, which
are part of our Technology segment.

     The Company's SFAS 142 evaluations were performed by management with the
assistance of a third-party valuation firm, utilizing assumptions and
projections we believe to be reasonable and supportable, and that reflect
management's best estimate of projected future cash flows. Considerable judgment
was required in selecting discount rates, developing cash flow projections and
developing balance sheets for each reporting unit. Slight changes in any of
these assumptions could create a material impact on the impairment charge
recorded by the Company.

DEFERRED TAX ASSET VALUATION AND TAX CONTINGENCIES

     In 2004 and 2003 (as restated), the Company recorded a $33.9 million and
$25.8 million charge, respectively, to establish a full valuation allowance for
its net deferred tax assets and net operating loss carryforwards. The valuation
allowance was calculated in accordance with the provisions of SFAS No. 109,
"Accounting for Income Taxes" ("SFAS 109"), which places primary importance on
the Company's operating results in the most recent three-year period when
assessing the need for a valuation allowance. Although we believe that our
results for the last three years were heavily affected by impairments and
planned restructuring activities, which were undertaken to right-size our cost
structure, the cumulative losses represented sufficient negative evidence to
require a valuation allowance under the provisions of SFAS 109. We intend to
maintain a valuation allowance until sufficient positive evidence exists to
support its reversal. Until such time, except for minor foreign and state tax
provisions, the Company will have no reported tax provision, net of valuation
allowance adjustments. See Note 8 -- Income Taxes, in the notes to consolidated
financial statements included herein, for additional information regarding this
charge.

     We are subject to ongoing examinations by certain taxation authorities of
the jurisdictions in which we operate. We regularly assess the status of these
examinations and the potential for adverse outcomes to

                                        59
<PAGE>

determine the adequacy of the provision for income and other taxes. We believe
that we have adequately provided for tax adjustments that we believe are
probable as a result of any ongoing examination.

RESTRUCTURING RESERVE

     Restructuring reserves include estimated costs for severance benefits,
lease termination expenses and other costs. If the future payments of these
costs were to differ from our estimates, we may need to increase or decrease our
reserves. Specifically, for leased premises that the Company no longer occupies,
management makes certain assumptions as to when or if these premises will be
subleased and at what price. Assumptions include the number of years of any
sublease, square footage, market trends, property locations and the price per
square foot. These assumptions involve significant judgments and estimations. We
have based our assumptions on discussions with brokers and/or parties that have
shown interest in the space.

     At each reporting date, we evaluate our accruals related to workforce
reduction charges, contract settlement and lease costs to ensure that these
accruals are still appropriate. In certain instances, we may determine that
these accruals are no longer required because of efficiencies in carrying out
our restructuring plan. In these cases, we reverse any related accrual to income
when it is determined that it is no longer required. Alternatively, in certain
circumstances, we may determine that certain accruals are insufficient as new
events occur or as additional information is obtained. In these cases, we would
increase the applicable existing accrual with the offset recorded against
income.

DIVESTITURES

     Pursuant to SFAS 142, reporting unit level goodwill should be allocated to
individual properties that are sold, if these properties qualify as a "business"
under Emerging Issues Task Force ("EITF") Issue No. 98-3, "Determining Whether a
Nonmonetary Transaction Involves Receipt of Productive Assets or of a Business"
("EITF 98-3"). We undertook a detailed analysis of each property sold in 2002,
2003 and 2004 to determine if it qualified as a business. Considerable judgment
is required to determine if a transferred set of activities possesses all of the
criteria for a business under EITF 98-3. In addition, further judgment is
required to determine if missing elements (for a business) are major or minor
items.

     The allocation of reporting unit goodwill to the individual properties is
further affected by whether a business is considered to be integrated. SFAS 142
states that if a business is not integrated, the initial goodwill that was
generated upon the acquisition of that business will be included in the
computation of the gain or loss on the disposition of that unit. Considerable
judgment is required to determine if a particular property has been integrated.
Factors such as length of time since acquisition, common management, knowledge
sharing, synergies between properties and shared services such as legal and
accounting have to be considered carefully in determining whether a property is
integrated. The Company has concluded that all the properties classified as
discontinued operations have been integrated, and as such, the goodwill has been
allocated to each property sold based on its relative fair value. The difference
between the initial goodwill generated upon acquisition and the amount allocated
using relative fair value can be material.

     In order for a property to be classified as discontinued operations, it
must meet the definition of a component under SFAS 144. A component is defined
as a reportable segment, a reporting unit, a subsidiary, an asset group or any
group of assets for which there is clearly distinguishable cash flows and such
cash flows will be eliminated upon the sale. This assessment requires
significant judgment.

PENSION PLANS

     Assumptions used in determining the projected benefit obligation and the
fair value of plan assets for our pension plans are determined by us in
consultation with our outside actuary. Changes in assumptions are based upon our
historical data, such as the rate of compensation increase and the long-term
rate of return on plan assets. Assumptions, including the discount rate and the
long-term rate of return on plan assets, are evaluated and updated at least
annually. Based upon our evaluation, we have changed the discount rate from
6.75% at December 31, 2002 to 6.0% at December 31, 2003, to 5.91% at December
31, 2004. We use a discount rate 1.0% lower for lump-sum distributions. The
discount rate decrease in 2003 and 2004 reflects the decrease in
                                        60
<PAGE>

Moody's Aa corporate bond yields, which were 6.52% at December 31, 2002, 6.01%
at December 31, 2003, and 5.66% at December 31, 2004 and the underlying stream
of expected benefit payments.

     Based upon our evaluation, we have changed our expected long-term rate of
return on plan assets to 8.5% from 9.0% used in 2002 and 2003. The expected
long-term rate of return of 8.5% is based on the actual historical rates of
return of published indices consistent with the plan's targeted asset
allocation. The historical rates are then discounted to consider fluctuations in
the historical rates as well as potential changes in the investment environment.

     Changes in pension expense may occur in the future due to changes in our
expected rate of return on plan assets and discount rate resulting from economic
events. A decrease of 0.25% in the discount rate would increase pension expense
approximately $0.3 million, while a decrease of 0.25% in the expected return on
asset rate would increase pension expense by approximately $0.1 million.

COMMITMENTS AND CONTINGENCIES

     We are subject to legal proceedings related to employment, intellectual
property, contract disputes and other matters. In order to determine the amount
of reserves required, we assess the likelihood of any adverse judgments or
outcomes to these matters as well as potential ranges of probable losses. A
determination of the amount of reserves required for these contingencies is made
after analysis of each individual issue and discussion with our legal counsel.
The required reserves may change in the future due to new developments in each
matter or changes in approach, such as a change in settlement strategy.

SELF INSURANCE

     The Company is self-insured for employee health benefits up to a certain
stop-loss limit. The Company is also self-insured in Ohio for workers
compensation up to a certain stop-loss limit. Such costs are accrued based on
known claims and an estimate of incurred, but not reported ("IBNR") claims. IBNR
claims are estimated using historical claims information and other data provided
by claims administrators. This estimation process is subjective, and to the
extent that future actual results differ from original estimates, adjustments to
recorded accruals may be necessary.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Market risk is the potential loss arising from adverse changes in market
rates and prices, such as foreign currency exchange rates and interest rates. We
do not enter into financial instruments for trading or speculative purposes. As
of December 31, 2004, the Company was exposed to the following market risks:

INTEREST RATE RISK

     Our cash and cash equivalents are not subject to significant interest rate
risk due to the short maturities of these instruments. As of December 31, 2004,
the carrying value of our cash and cash equivalents approximates fair value.

FAIR VALUE RISK

     Our long-term debt consists of senior notes with interest at fixed rates.
Consequently, we do not have significant interest rate risk exposure related to
our long-term debt. However, the fair value of our senior notes fluctuates with
the market, as they are publicly traded.

FOREIGN CURRENCY EXCHANGE RATE RISK

     We maintain assets and operations in the United Kingdom and in various
other countries. As a result, we may be exposed to fluctuations in currency
rates relative to these markets. At December 31, 2004, a hypothetical 10%
strengthening or weakening of the U.S. dollar relative to the currencies of
foreign countries in which we operate would have resulted in an immaterial
impact on our financial results and cash flows.

2003 MARKET RISK

     At December 31, 2003, the Subordinated Notes had a carrying amount of
$171.7 million and a fair value of $116.8 million and the Secured Notes had a
carrying amount of $156.9 million and a fair value of $153.0 million. The fair
value of the notes is determined by quotations in the open market.

     At December 31, 2003, the Company was exposed to interest rate risk due to
the variable rate on our notes receivable. As of December 31, 2003, a
hypothetical 10% increase in the interest rate would have resulted in an
immaterial impact on our financial results and cash flows.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of Penton Media, Inc.:

     In our opinion, the consolidated financial statements listed in the
accompanying index present fairly, in all material respects, the financial
position of Penton Media, Inc. (the "Company") and its subsidiaries at December
31, 2004 and 2003, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 2004, in conformity
with accounting principles generally accepted in the United States of America.
In addition, in our opinion, the financial statement schedule listed in the
accompanying index presents fairly, in all material respects, the information
set forth therein when read in conjunction with the related consolidated
financial statements. These financial statements and financial statement
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these financial statements and the financial
statement schedule based on our audits. We conducted our audits of these
statements in accordance with standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, 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 our opinion.

     As discussed in Note 1 -- Description of Business and Significant
Accounting Policies to the consolidated financial statements, effective January
1, 2002, the Company changed its method of accounting for goodwill and other
intangible assets to comply with the provisions of Statement of Financial
Accounting Standards No. 142, "Goodwill and Other Intangible Assets."

     As described in Note 2 -- Restatement to the consolidated financial
statements, the Company has restated its previously issued consolidated
financial statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

     Penton Media, Inc. ("Penton" or the "Company"), which was founded in 1892,
is a leading diversified business-to-business media company. Penton became an
independent company, incorporated in the State of Delaware, as a result of our
spin-off from Pittway Corporation in August 1998. Penton provides media products
that deliver proprietary business information to owners, operators, managers and
professionals in the industries that are served. Through these products, the
Company offers industry suppliers multiple ways to reach their customers and
prospects as part of their sales and marketing efforts. The Company publishes
specialized trade magazines, produces trade shows and conferences, and provides
a range of online media products, including Web sites, electronic newsletters
and Web-based conferences.

     In 2004, the Company implemented a change in its reportable segments to
conform with the way the Company's businesses are now assessed and managed. Our
five segments are Industry, Technology, Lifestyle, Retail and International. Our
segments are structured along industry lines, which enables the Company to
promote our related groups of products to our customers. Penton's integrated
media portfolios serve the following markets: design/engineering,
government/compliance, manufacturing, mechanical systems/construction, aviation,
Internet technologies, enterprise information technology, electronics, natural
products, food/retail and leisure/hospitality.

PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States of America and
include the accounts of the Company and each of its subsidiaries. All
intercompany accounts and transactions have been eliminated in consolidation.

     The financial statements of entities, which are controlled by Penton
through voting equity interests are consolidated. Entities that are jointly
controlled and entities that are not controlled, but those on which Penton has
the ability to exercise significant influence, are accounted for using the
equity method. Variable Interest Entities ("VIEs"), which include, but are not
limited to, special purpose entities, trusts, partnerships, certain joint
ventures and other legal structures, as defined in Financial Accounting
Standards Board ("FASB") Interpretation ("FIN") No. 46 (Revised 2003),
"Consolidation of Variable Interest Entities -- an Interpretation of Accounting
Research Bulletin No. 51" ("FIN 46(R)"), are entities in which equity investors
do not have the characteristics of a "controlling financial interest" or there
is not sufficient equity at risk for the entity to finance its activities
without additional subordinated financial support. VIEs are consolidated by
Penton when it is determined that Penton will, as the primary beneficiary,
absorb the majority of a VIE's expected losses and/or expected residual returns.
The Company presently does not hold an interest in any VIEs.

USE OF ESTIMATES

     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles in the United States of America
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. Management reviews its estimates based
upon currently available information on an ongoing basis. Actual results could
differ from these estimates.

CASH AND CASH EQUIVALENTS, AND RESTRICTED CASH

     Cash and cash equivalents include primarily cash on hand and short-term
investments with original maturity of three months or less. At December 31,
2004, the Company had $0.1 million of restricted cash,

                                        70

                               PENTON MEDIA, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

related to medical self insurance requirements. At December 31, 2004 and 2003,
the Company had cash overdrafts of $0.5 million and $0.2 million, respectively.

ALLOWANCE FOR DOUBTFUL ACCOUNTS RECEIVABLE

     The Company establishes its credit policies based on an ongoing evaluation
of its customers' credit worthiness and competitive market conditions and
establishes its allowance for doubtful accounts based on an assessment of
exposures to credit losses at each balance sheet date. Trade accounts receivable
are considered past due after 30 days and delinquent after 90 days. The Company
believes its allowance for doubtful accounts is sufficient based on the credit
exposures outstanding at December 31, 2004.

INVENTORIES

     Inventories, which consist primarily of paper stock, are stated at the
lower of cost or market, cost being determined on the basis of the last-in,
first-out ("LIFO") method. The difference between cost determined on a LIFO
basis and a first-in, first-out basis was insignificant at December 31, 2004 and
2003.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Penton records depreciation
using the straight-line method over the following estimated useful lives:

<Table>
<S>                                         <C>
Computer equipment and software..........   3-5 years
Web site development costs...............   3 years
Furniture, fixtures and equipment........   3-10 years
Leasehold improvements...................   Estimated useful lives or lease term,
                                            whichever is shorter
</Table>

     Depreciation expense was $6.4 million, $8.0 million and $8.8 million for
the years ended December 31, 2004, 2003 and 2002, 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 operations.

GOODWILL, OTHER INTANGIBLE ASSETS AND LONG-LIVED ASSETS

     The Company adopted Statement of Financial Accounting Standards ("SFAS"),
No. 142, "Goodwill and Other Intangible Assets" ("SFAS 142"), on January 1,
2002. Under SFAS 142, goodwill and certain other intangible assets having
indefinite lives, which were previously amortized over the periods benefited,
are no longer being amortized to earnings, but instead are subject to periodic
testing for impairment. The Company does not have other intangibles with
indefinite lives. Goodwill is tested for impairment on an annual basis or
between annual tests if events occur or circumstances change that could indicate
a reduction in the fair value of a reporting unit below its carrying amount. If
the carrying amount of the reporting unit's goodwill exceeds the implied fair
value of that goodwill, an impairment loss is recognized in an amount equal to
that excess.

     In January 2002, the Company also adopted SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets" ("SFAS 144"). This statement
requires long-lived assets with determinable lives to be grouped with other
assets and liabilities at the lowest level for which there are identifiable cash
flows that are largely independent of the cash flows of other groups of assets
and liabilities. An impairment exists only if the carrying amount of the
long-lived assets, or group, is not recoverable and exceeds its fair value.
Intangible

                                        71

                               PENTON MEDIA, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

assets determined to have definite lives are amortized over their remaining
useful lives. Intangible and other long-lived assets with determinable lives are
reviewed for impairment whenever events and circumstances indicate that the
carrying amount may not be recoverable pursuant to SFAS 144. In reviewing for
impairment, the Company compares the undiscounted cash flows generated by such
assets to the carrying value of such assets. If the total cash flows are less
than the carrying amount, the Company compares the carrying value of such assets
to the fair value determined using the income approach, which is similar to the
discounted cash flows approach. Impairment is recognized equal to the difference
between the asset's fair value and its carrying amount.

DEFERRED FINANCING COSTS

     Costs incurred in obtaining long-term financing are included in other
non-current assets, in the accompanying consolidated balance sheets, and are
amortized over the term of there related indebtedness using the effective
interest method.

REVENUE RECOGNITION

     Advertising revenues from Penton's trade magazines are recognized in the
month the publications are mailed. Subscription revenues are recognized over the
subscription period, typically one year. Amounts received in advance of trade
shows and conferences are deferred and recognized on the last day of the event,
in the month the event is held. Online media revenues primarily include
advertising revenues such as banner advertising, sponsorships, e-newsletters,
e-books and web seminars. Revenue is recognized in the period the obligation is
fulfilled or delivered.

     When a sale involves multiple deliverables where the deliverables are
governed by more than one authoritative standard, the Company evaluates all
deliverables to determine whether they represent separate units of accounting
based on the following criteria:

     - whether the delivered item has value to the customer on a stand-alone
       basis;

     - whether there is objective and reliable evidence of the fair value of the
       undelivered item(s); and

     - if the contract includes a general right of return relative to the
       delivered item, delivery or performance of the undelivered item(s) is
       considered probable and is substantially in our control.

     Our determination of whether deliverables within a multiple element
arrangement can be treated separately for revenue recognition purposes involves
significant estimates and judgment, such as whether fair value can be
established on undelivered obligations and/or whether delivered elements have
standalone value to the customer. Changes in our assessment of the accounting
units in an arrangement and/or our ability to establish fair values could
significantly change the timing of revenue recognition.

ADVERTISING AND PROMOTION EXPENSES

     Advertising and promotion costs are expensed as incurred. These costs
amounted to $6.4 million, $6.7 million and $11.9 million in 2004, 2003 and 2002,
respectively.

SELF INSURANCE

     The Company is self-insured for a portion of its risk on workers'
compensation and employee medical costs. The arrangements provide for stop loss
insurance to manage the Company's risk. Operations are charged with the cost of
claims reported and an estimate of claims incurred but not reported. The Company
does not provide health care benefits to retired employees.

                               PENTON MEDIA, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

INCOME TAXES

     Income taxes are accounted for using the asset and liability method
pursuant to the provisions of SFAS No. 109 "Accounting for Income Taxes" ("SFAS
109"). Deferred tax assets and liabilities are recognized for the expected
future tax consequences attributable to temporary differences between the
financial statement carrying amounts and the tax basis of assets and
liabilities. Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.

     The Company assesses the recoverability of its deferred tax assets in
accordance with SFAS 109. Accordingly, the Company recorded a valuation
allowance for its net deferred tax assets and net operating loss carryforwards
of $106.0 million and $72.1 million as of December 31, 2004 and 2003,
respectively. See Note 8 -- Income Taxes for additional information.

RESTRUCTURING

     The Company adopted SFAS No. 146, "Accounting for Costs Associated with
Exit or Disposal Activities," ("SFAS 146") effective for all exit or disposal
activities initiated after December 31, 2002. SFAS 146 requires that liabilities
for costs associated with exit or disposal activities be recognized when the
liabilities are incurred, rather than when an entity commits to an exit plan.
SFAS 146 changes the timing of liability and expense recognition related to exit
or disposal activities, but not the ultimate amount of such expenses.

TRANSLATION OF FOREIGN CURRENCIES

     The functional currency of Penton's foreign operations is their local
currency. Accordingly, assets and liabilities of foreign operations are
translated to U.S. dollars at the rates of exchange at year-end; income and
expense are translated at the average rates of exchange prevailing during the
applicable year. The effects of translation are included in accumulated other
comprehensive loss in stockholders' equity (deficit). There were no significant
foreign currency transaction gains or losses in 2004, 2003 or 2002.

STOCK BASED COMPENSATION PLANS

     At December 31, 2004, the Company has various stock-based compensation
arrangements (see Note 13 -- Common Stock and Common Stock Award Programs). The
Company accounts for these plans under the recognition and measurement
principles of Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees" ("APB 25"), and related interpretations. For stock option
plans, no compensation is recognized as all grants are issued at the market
value of the Company's stock.

     The following table illustrates the effects on net loss and earnings per
share as if the Company had applied the fair value recognition provision of SFAS
No. 123, "Accounting for Stock-Based Compensation"

EARNINGS PER SHARE

     Basic earnings per share are based upon the weighted-average number of
common shares outstanding plus the weighted-average number of fully vested
Restricted Stock Units and deferred shares. Diluted earnings per share also
includes the effect of stock options and other common stock equivalents
outstanding during the period, if they are dilutive. In periods of a net loss
position, basic and diluted weighted average shares are the same.

NEW ACCOUNTING STANDARDS

     In March 2004, the Emerging Issues Task Force ("EITF") reached a final
consensus on EITF Issue 03-6, "Participating Securities and the Two-Class Method
Under FASB Statement 128, Earnings Per Share" ("EITF 03-6"). EITF 03-6 addresses
the computation of earnings per share by companies that have issued securities
other than common stock that participate in dividends and earnings of the
issuing entity. EITF 03-6 is effective for the quarter ended June 30, 2004 and
requires the restatement of previously reported earnings per share. The adoption
of this issue did not have an effect on the Company's earnings per share as the
Company already used the two-class method for its participating securities.

     In December 2004, the FASB issued SFAS 123 (revised 2004), "Share-Based
Payment" ("SFAS 123(R)"), which replaces SFAS 123 and supersedes APB 25. SFAS
123-R requires recognition of an expense when a company exchanges its equity
instruments for goods or services, based on the fair value of the share-based
compensation at the grant date. The related expense is recognized over the
period in which the share-based compensation vests. SFAS 123(R) permits either a
prospective or one of two modified

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

versions of retrospective application under which financial statements for prior
periods are adjusted on a basis consistent with the pro forma disclosures
required for those periods by the original SFAS 123. The Company is required to
adopt the provisions of SFAS 123(R) effective January 1, 2006, at which time the
Company will begin recognizing an expense for unvested share-based compensation
that has been issued or will be issued after that date. Prior periods may be
restated. In March 2005, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 107, "TOPIC 14: Share-based payment" ("SAB 107").
SAB 107 addresses the interaction between SFAS 123(R) and certain SEC rules and
regulations and provides views regarding the valuation of share-based payment
arrangements for public companies. This bulletin is effective immediately. The
Company has not yet finalized its decision concerning the transition method it
will utilize to adopt SFAS 123(R) and its impact on the financial statements.

     In March 2005, the FASB Staff issued Interpretation No. 47, "Accounting for
Conditional Asset Retirement Obligations" ("FIN 47"). FIN 47 clarifies the term
conditional asset retirement obligation as used in FASB Statement No. 143,
"Accounting for Asset Retirement Obligations" as well as other issues related to
asset retirement obligations. FIN 47 is effective for fiscal years ending after
December 15, 2005. The Company is in the process of determining if this
interpretation will have any impact on its financial statements.

NOTE 2 -- RESTATEMENT

     The consolidated financial statements for the years ended December 31, 2003
and 2002 and the related quarterly financial data for the years ended December
31, 2004 and 2003 included in this Annual Report on Form 10-K have been restated
to reflect adjustments to our previously reported quarterly financial data and
annual financial statements included in our Form 10-K for the year ended
December 31, 2003. In addition, previously filed quarterly financial data on
Form 10-Q for the quarters ended March 31, 2004, June 30, 2004 and September 30,
2004 have been restated in this annual report on Form 10-K. See Note
21 -- Quarterly Results (Unaudited) for the effect of the restatement on
quarterly periods of 2004 and 2003. The Company intends to file amendments to
all of our 2004 Form 10-Qs as expeditiously as possible.

     The Company performed a comprehensive review of the Company's deferred tax
assets and deferred tax liabilities and determined that certain deferred tax
liabilities had been incorrectly offset against its deferred tax assets. In
addition to correcting the deferred tax issue, the restatement also includes
other accounting adjustments that were deemed in earlier periods to be
immaterial. The cumulative effect of these corrections is an increase in
stockholders' deficit at December 31, 2003 and September 30, 2004 of $15.4
million and $17.1 million (unaudited), respectively. The corrections are further
described as follows:

DEFERRED TAX ADJUSTMENTS

     On March 24, 2005, the Company's management concluded that its previously
issued consolidated financial statements should be restated to increase income
tax expense and establish a corresponding deferred tax liability of $6.8 million
and $10.1 million for the years ended December 31, 2003 and 2002, respectively,
to correct the computation of our valuation allowance for deferred tax assets
over those periods.

     Management reached this conclusion following a comprehensive review of the
Company's deferred tax assets and deferred tax liabilities. Under SFAS 109,
taxable temporary differences related to indefinite-lived intangible assets or
tax-deductible goodwill (for which reversal cannot be anticipated) should not
have been offset by the Company against deductible temporary differences for
other indefinite-lived intangible assets or tax-deductible goodwill when
scheduling reversals of temporary differences.

OTHER ACCOUNTING ADJUSTMENTS

     Other accounting adjustments represent items previously identified but
deemed to be immaterial and recorded in the period Penton identified the error
or in a subsequent period. Adjustments in this category

change the timing of income and expense items that were previously recognized.
The impact of these adjustments was a decrease in net loss of $1.7 million in
2003 and an increase in net loss of $1.7 million in 2004. Of this amount, the
largest item represents an adjustment of $2.0 million between the third quarter
of 2003 and the fourth quarter of 2004. In September 2003, our minority interest
in consolidated subsidiaries balance should have been reduced when certain
assets contributed in 2002 by our minority interest partner were impaired.
Additionally, revenues were reduced by approximately $0.2 million in 2002 due to
the reclassification of sales discounts, which were originally classified in
selling, general and administrative expenses. The amortization of deemed
dividend and accretion of preferred stock decreased by $0.3 million in 2003 and
increased by $0.3 million in 2002. In June 2003, it was discovered that the
Company should not have only been accruing the dividends on the preferred stock
from the time of issuance but should have also been accreting some of the
preferred stock. Other less significant income statement adjustments were also
recorded for items related to tenant improvements in 2001, and subscription
revenues and restructuring charges in 2003.

     The following adjustments affected the classification of certain balance
sheet accounts:

     - In February 2004, a tentative settlement agreement was reached in the
       Meckler lawsuit. The settlement amount of $4.6 million, which was paid in
       its entirety by Penton's insurance company, should have been recorded as
       a liability and corresponding receivable at December 31, 2003, as
       required by FIN 39, "Offsetting of Amounts Related to Certain Contracts."
       The 2003 restated balance sheet includes the $4.6 million in current
       assets under prepayments, deposits and other and in current liabilities
       under other accrued expenses.

     - At December 31, 2003 certain trade show receivables were recorded at
       their full contract amounts even though the contract stipulated that only
       a portion of the contract was due. This correction reduced accounts
       receivable and unearned income by $2.6 million.

     - Other less significant balance sheet adjustments were also recorded for
       items related to tenant improvements in 2001, and subscription revenues,
       restructuring charges and accounts payable in 2003.

OTHER

     All previously reported amounts affected by the restatement that appear
elsewhere in these notes to the consolidated financial statements have also been
restated.

NOTE 3 -- DISPOSALS

     In December 2004, the Company completed the sale of 70% of its interest in
PM Germany, a consolidated subsidiary, to Neue Medien Ulm Holdings GmbH ("Neue
Medien") for $0.8 million in cash. The sale did not qualify as discontinued
operations under SFAS 144; consequently, the related loss on sale of $0.9
million is included in loss (gain) on sale of properties, on the accompanying
consolidated statements of operations. At December 31, 2004, the Company retains
a 15% interest in PM Germany, which includes a call/put option. The Company
accounts for its investment using the cost method, as the Company does not
exercise significant influence.

     At December 31, 2002, the net assets of our Professional Trade Shows
("PTS") group were classified as held for sale. The sale was completed in
January 2003 for approximately $3.8 million, including an earnout of $0.6
million based on reaching certain performance objectives in 2003. At December
31, 2003, these performance objectives had not been reached. The sale resulted
in a gain of approximately $1.4 million, which was recorded in the first quarter
of 2003. PTS was part of our Industry segment. The results of PTS are reported
as discontinued operations for all periods presented.

     In December 2002, the Company disposed of the net assets of Penton Media
Australia ("PM Australia") for approximately $0.01 million in cash at closing
and $0.1 million received through July 2004. The sale resulted in a loss of
approximately $0.6 million. PM Australia was part of our Technology segment. The
results of PM Australia are reported as discontinued operations for all periods
through the date of sale.

     In addition to the above components, the Company recognized a $0.9 million
loss included in operating expenses as loss on sale of properties related to the
sale of four properties in December 2002, including Streaming Media, Boardwatch
and ISPCON, which were part of our Technology segment, and AEC, which was part
of our Industry segment. The aggregate consideration for these properties was
approximately $0.9 million in cash.

NOTE 4 -- ACCOUNTS RECEIVABLE, NET

     Trade accounts receivable are recorded at the invoiced amount and do not
bear interest. The allowance for doubtful accounts is our best estimate of the
amount of probable credit losses in our existing accounts receivable. The
Company determines the allowance based on historical write-off experience by
industry and regional economic data. The Company reviews the allowance for
doubtful accounts monthly. Past due balances over 90 days and over a specified
amount are reviewed individually for collectibility. All other balances are
charged against the allowance when the Company believes it is probable the
receivable will not be recovered. We do not have any off-balance-sheet credit
exposure related to our customers.

     Accounts receivable, net consist of the following at December 31, 2004 and

NOTE 6 -- GOODWILL AND OTHER INTANGIBLES

IMPAIRMENT OF GOODWILL

     The Company has selected September 30 of each year to perform its annual
impairment reviews under SFAS 142, which are performed by management with the
assistance of a third party valuation firm. The evaluations utilize both an
income and market valuation approach and contain reasonable and supportable
assumptions and projections and reflect management's best estimate of projected
future cash flows. If the assumptions and estimates underlying these goodwill
impairment evaluations are not achieved, additional impairment charges may be
necessary. Impairment charges are reflected as impairment of assets in the
accompanying consolidated statements of operations.

     In 2004, the Company recorded a non-cash goodwill impairment charge of
$37.8 million. This goodwill impairment charge is due primarily to lower than
previously expected future cash flows in two reporting units in our Technology
segment and by lower than previously expected future cash flows in our
International segment.

     In 2003, the Company recorded a non-cash goodwill impairment charge of
$37.6 million. This goodwill impairment charge is due primarily to the reduction
of the fair value of goodwill in three of our reporting units due to lower than
previously expected future cash flows. Two of the reporting units are part of
the Company's Technology segment and one is part of our Retail segment.

     During the third quarter of 2002, Penton completed its initial impairment
test under the provisions of SFAS 142 for January 1, 2002 and recorded a
non-cash goodwill impairment charge of $39.7 million to reduce the carrying
value of goodwill for two of our reporting units in the Technology segment. The
charge is reflected as a cumulative effect of an accounting change in the
accompanying consolidated statements of operations.

     During the third quarter of 2002, a number of events occurred that
indicated an additional possible impairment of goodwill might exist. These
events included our determination in July of lower-than-expected revenues and
adjusted EBITDA results for the year; a letter from the New York Stock Exchange
indicating that the Company had fallen below minimum listing standards; a
significant decline in the Company's stock price; and the decision by management
to potentially sell or dispose of certain non-core assets. As a result of these
triggering events and circumstances, the Company completed an additional SFAS
142 impairment

review at September 30, 2002. This review resulted in a non-cash goodwill
impairment charge of approximately $203.3 million to further reduce the carrying
value of goodwill for two reporting units in our Technology segment.

(2) The $2,790 consists of acquisition costs reclassified to goodwill and

(3) Represents goodwill related to PM Germany, which was sold in December 2004.

IMPAIRMENT OF LONG-LIVED ASSETS

     Due to the impairments of goodwill in 2004, 2003 and 2002, the Company also
completed annual assessments of its long-lived assets in accordance with the
provisions of SFAS 144 and recorded non-cash charges of $1.9 million, $6.2
million and $20.0 million in 2004, 2003 (as restated) and 2002, respectively.
These charges relate primarily to the write-off of trade names and subscriber
and advertiser relationships for properties in our Technology segment.

     The fair value of the asset groups was determined using the income
approach, which is similar to the discounted cash flows approach. The charges
are reflected as impairment of assets in the accompanying consolidated
statements of operations.

NOTE 7 -- DEBT

LOAN AND SECURITY AGREEMENT

     In August 2003, the Company entered into a four-year revolving loan and
security agreement. Pursuant to the terms of the loan and security agreement,
the Company can borrow up to the lesser of (i) $40.0 million; (ii) 2.25x the
Company's last twelve months adjusted EBITDA measured monthly through August 13,
2005 and 2.0x thereafter; (iii) 40% of the Company's last six months of
revenues; or (iv) 25% of the Company's enterprise value, as determined annually
by a third party. The revolving credit facility bears interest at LIBOR plus
5.0% subject to a LIBOR minimum of 1.5%. The Company must comply with a
quarterly financial covenant limiting the ratio of maximum bank debt to the last
twelve months adjusted EBITDA to 2.25x from June 30, 2004 through March 31, 2005
and 2.0x thereafter. The loan agreement permits the Company to sell assets of up
to $12.0 million in the aggregate during the term or $5.0 million in any single
asset sale; and

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

complete acquisitions of up to $5.0 million per year. Included in the loan
agreement are two stand-by letters of credit of $0.1 million and $0.2 million,
respectively, required by two of the Company's facility leases. The amounts of
the letters of credit reduce the availability under the credit facility. As of
December 31, 2004, no amounts were drawn under the stand-by letters of credit.
Costs representing bank fees and other professional fees of $1.9 million are
being amortized over the life of the loan agreement. At December 31, 2004, $39.7
million was available under the loan agreement. There were no amounts
outstanding, see Note 23 -- Subsequent Events.

     The loan and security agreement contains several provisions, which could
have a significant impact as to the classification as well as the acceleration
of payments for borrowings outstanding under the agreement, including the
following: (i) the obligation of the lender to provide any advances under the
loan agreement is subject to no material adverse change events; (ii) reserves
may be established against the borrowing base for sums that the Company is
required to pay, such as taxes and assessments and other types of required
payments, and has failed to pay; (iii) in the event of a default under the loan
agreement, the lender has the right to direct all cash that is deposited in the
Company's lock boxes to be sent to the lender to pay down outstanding
borrowings; (iv) the loan agreement establishes cross-defaults to the Company's
other indebtedness (such as the 11 7/8% senior secured notes and 10 3/8% senior
subordinated notes) such that a default under the loan agreement could cause a
default under the note agreements and vice versa; however, default-triggering
thresholds are different in the loan agreement and the notes; (v) if the Company
is in default of any material agreement to which it is a party and the
counter-party to that agreement has the right to terminate such agreement as a
result of the default, this constitutes an event of default under the loan
agreement. Under the loan agreement, the lenders reserve the right to deem the
notes in default, and in those limited circumstances, could accelerate payment
of the outstanding loan balances should the Company undergo a material adverse
event. Even though the criteria defining a material adverse event are
subjective, the Company does not believe that the exercise of the lenders' right
is probable nor does it foresee any material adverse events in 2005. In
addition, the Company believes that the 11 7/8% senior secured and 10 3/8%
senior subordinated note agreements are long-term in nature. Accordingly, the
Company continues to classify its notes as long term. See Note 23 -- Subsequent
Events.

SENIOR SECURED NOTES

     In March 2002, Penton issued $157.5 million of 11 7/8% senior secured notes
(the "Secured Notes") due in 2007. Interest is payable on the Secured Notes
semiannually on April 1 and October 1. The Secured Notes are fully and
unconditionally, jointly and severally guaranteed on a senior basis by all of
the assets of Penton's domestic subsidiaries, which are 100% owned by the
Company, and also by the stock of certain subsidiaries. Condensed consolidating
financial information is presented in Note 22 -- Guarantor and Non-guarantor
Subsidiaries. Penton may redeem the Secured Notes, in whole or in part, during
the periods October 1, 2005 through October 1, 2006 and thereafter at redemption
prices of 105.9% and 100.0% of the principal amount, respectively, together with
accrued and unpaid interest. In addition, at any time prior to October 1, 2005,
up to 35% of the aggregate principal amount of the Secured Notes may be redeemed
at Penton's option, within 90 days of certain public equity offerings of its
common stock, at a redemption price equal to 111.875% of the principal amount,
together with accrued and unpaid interest.

     The Secured Notes were offered at a discount of $0.8 million, which is
being amortized using the interest method, over the term of the Secured Notes.
In 2004, 2003 and 2002, respectively, the Company recorded $0.3 million, $0.2
million and $0.1 million of amortization expense related to the discount. Costs
representing underwriting fees and other professional fees of $6.6 million are
being amortized, using the effective interest method, over the term of the
Secured Notes. Net proceeds of $150.1 million were used to pay down $83.6
million of Penton's term loan A facility and $49.0 million of its term loan B
facility under the Company's previous loan agreement and to repurchase $10.0
million of the Company's 10 3/8% senior subordinated notes for $8.3 million,
excluding interest. The remaining net proceeds of $9.2 million were used
                                        84

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

for general corporate purposes. The Secured Notes rank senior in right to all of
Penton's subordinated indebtedness, including the 10 3/8% senior subordinated
notes due in 2011. The indenture governing the Secured Notes contains covenants
that, among other things, limit the Company's ability to pay dividends, incur
additional debt, sell assets and enter into mergers or consolidations. The
Company's ability to obtain dividends from its subsidiaries is only restricted
if Penton is in default under its debt arrangement or if the Company has
exceeded its limitation of additional indebtedness, as specified in the
indenture.

SENIOR SUBORDINATED NOTES

     In June 2001, Penton issued $185.0 million of 10 3/8% senior subordinated
notes (the "Subordinated Notes") due in 2011. Interest is payable on the
Subordinated Notes semiannually on June 15 and December 15. The Subordinated
Notes are fully and unconditionally, jointly and severally guaranteed, on a
senior subordinated basis, by the assets of Penton's domestic subsidiaries,
which are 100% owned by the Company. Condensed consolidating financial
information is presented in Note 22 -- Guarantor and Non-guarantor Subsidiaries.
The notes may be redeemed in whole or in part on or after June 15, 2006. The
Subordinated Notes were offered at a discount of $4.2 million, which is being
amortized using the interest method, over the term of the Subordinated Notes. In
2004, 2003 and 2002, respectively, the Company recorded $1.0 million, $0.6
million and $0.4 million of amortization expense related to the discount. Costs
representing underwriting fees and other professional fees of $1.7 million are
being amortized over the term of the Subordinated Notes. Net proceeds of $180.2
million were used to pay down $136.0 million under our previous revolving credit
facility, $12.8 million under our previous term loan A and $7.2 million under
our previous term loan B. The remaining net proceeds of $24.2 million were used
for general corporate purposes. The Subordinated Notes are unsecured senior
subordinated obligations of the Company, subordinated in right of payment to all
existing and future senior indebtedness of the Company, including the credit
facility. The indenture governing the Subordinated Notes contains covenants
that, among other things, restrict the Company's ability to borrow money, pay
dividends on or repurchase capital stock, make investments, sell assets and
enter into mergers or consolidations. The Company's ability to obtain dividends
from its subsidiaries is only restricted if Penton is in default under its debt
arrangement or if the Company has exceeded its limitation of additional
indebtedness, as specified in such agreement.

     In March 2002, the Company repurchased $10.0 million of its Subordinated
Notes with $8.7 million of the proceeds from the Secured Notes offering,
completed in March 2002, resulting in a gain of $1.4 million, which is
classified in other net in the consolidated statements of operations.

CASH PAID FOR INTEREST

     Cash paid for interest for 2004, 2003 and 2002 was $36.9 million, $36.9
million and $29.9 million, respectively.

     Included in interest expense in the consolidated statements of operations
for the years ended December 31, 2003 and 2002 are write-offs of unamortized
financing fees of approximately $1.9 million and $0.7 million, respectively,
related to refinancing of debt. In addition, 2003 interest expense includes a
net deferred loss on cash flow hedges of $1.4 million and net losses on interest
swaps that did not qualify as hedges under SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities" ("SFAS 133") of $0.1 million.

     SFAS 109 required that deferred tax assets be reduced by a valuation
allowance, if based on available evidence, it is more likely than not that the
deferred tax assets will not be realized. Under generally accepted accounting
principles, available evidence includes the reversal of existing taxable
temporary differences. Upon the adoption of SFAS 142 on January 1, 2002 (See
Note 1 -- Description of Business and Significant Accounting Policies), the
Company can no longer amortize tax deductible goodwill and indefinite-lived
intangible assets for financial reporting purposes. Therefore, the deferred tax
liability related to the taxable temporary differences caused by different
amortization periods for identified intangibles will not reverse unless the
underlying assets are sold or an impairment is recorded. The Company had net
deferred tax liabilities related to indefinite-lived intangibles for 2004, 2003
and 2002 of $19.6 million, $17.0 million and $10.1 million respectively. As the
Company has cumulative losses in recent years, it recorded valuation allowances
to offset their respective annual income tax benefits from operations as well as
the amount by which their deferred tax assets exceeded their deferred tax
liabilities, excluding the deferred tax liability related to indefinite-lived
intangibles. In 2003 and 2002, the Company established a valuation allowance
related to discontinued operations and cumulative effect of accounting change of
$3.0 million and $3.7 million, respectively.

     At December 31, 2004, the Company had federal operating loss carryforwards
of $142.7 million for tax purposes, which will begin expiring from 2022 to 2024.
A full valuation has been provided on the federal operating loss carryforwards.

     At December 31, 2004, the Company had state operating loss carryforwards of
$373.6 million for tax purposes, which will begin expiring from 2006 to 2024. A
full valuation has been provided on the state operating loss carryforwards.

     At December 31, 2004, the Company had available foreign tax credit
carryforwards of approximately $1.1 million, which will begin expiring from 2007
to 2008. A full valuation allowance has been provided on the foreign tax credit
carryforwards.

     During 2004, the Company paid net cash tax payments of $0.7 million ($0.2
million of tax refunds for prior years less cash paid for taxes in 2004 of $0.9
million). For 2003 and 2002, net cash tax refunds were $52.0 million and $17.6
million, respectively.

     Prior to 2004, the Company did not provide for federal income taxes or tax
benefits on the undistributed earnings or losses of its international
subsidiaries because earnings were considered indefinitely reinvested, in the
opinion of management. In 2004 the Company has provided federal income tax
benefits, subject to valuation allowance, on temporary differences on certain
international subsidiaries.

     The American Job Creation Act of 2004 was signed into law in October of
2004. Due to the Company's U.S. tax loss position, the law should not have a
material impact on our income taxes.

NOTE 9 -- EMPLOYEE BENEFIT PLANS

     Penton maintains three retirement plans: a defined benefit plan; a
supplemental executive retirement plan ("SERP"); and a defined contribution
plan.

DEFINED BENEFIT PLAN AND SERP

     Penton's defined benefit pension plan covers all employees who were Plan
participants at December 31, 2003. Retirement benefits for employees in foreign
countries generally are provided by national statutory programs. Benefits for
domestic employees are based on years of service and annual compensation as
defined by the plan.

     In November 2003, the Company's defined benefit plan was amended to freeze
the accrual of any benefits under the plan after December 31, 2003. As a result,
the Company recorded a curtailment gain of $2.2 million for the year ended
December 31, 2003. This amount is included in selling, general and
administrative expenses in the consolidated statements of operations. The
benefit accruals in the frozen plan are payable to participating employees when
they qualify for retirement.

     Restructuring efforts in 2002 triggered a need for a revised valuation of
our defined benefit pension plan. Pursuant to this revised valuation, the
Company recorded a curtailment gain of $0.9 million and a settlement gain of
$1.1 million in 2002. These amounts have been recorded as part of selling,
general and administrative expenses on the consolidated statements of
operations. Due to this revised valuation, the Company also updated its
assumptions resulting in additional pension expense of $0.7 million for 2002.

     In November 2003, Penton's SERP was amended to freeze benefits effective on
January 1, 2004. As a result, the Company recorded a curtailment charge of $0.3
million for the year ended December 31, 2003. This amount is included in
selling, general and administrative expenses in the consolidated statements of
operations. In place of the SERP, the Company will accrue throughout the year an
amount equal to between 3% and 6% of the participants eligible salary plus an
investment return equal to the Moody's AA Corporate Bond note. The accrued
percentage is based on each executive's age and years of service.

     As a result of the elimination of four plan participants, the SERP was
revalued in 2002. Pursuant to this revised valuation, the Company recorded a
curtailment charge of $0.1 million and an immaterial settlement charge, which
were recorded as part of selling, general and administrative expenses on the
consolidated statements of operations. The SERP plan is an unfunded,
non-qualified plan and hence has no plan assets.

INVESTMENT POLICY

     The Investment Committee of the Board of Directors has developed and
implemented an investment policy to effectively manage the defined benefit plan
assets in the context of meeting the plan's obligations. The portfolios
investment objectives are to maximize plan assets within designated risk and
return profiles; optimize returns of invested assets consistent with prudent
risk-taking; provide returns that exceed relevant market averages and benchmarks
of comparable size portfolios; and produce returns that are consistent with
those of asset classes indices weighted by policy target weights. All assets are
managed externally according to guidelines the Company has established
individually with the investment manager. Fixed income securities are required
to carry a AA or better rating, those not carrying these ratings require
approval of the Investment

Committee. The Investment Committee periodically reviews the overall plan
performance, the risk level, asset allocation and the investment manager's
performance to evaluate the effectiveness of the program.

     The current asset allocation consists primarily of listed stocks and
corporate bonds. Investment policy decisions and asset allocation strategies are
refined based on information, analysis and recommendations as provided by the
investment manager. The following table indicates Penton's 2005 targeted asset
allocation and breaks down its 2004 and 2003 asset allocation:

     For 2004, the Company assumed a long-term rate of return of 8.5%. In
developing this rate, the Company evaluated the actual historical rates of
return for the plan since Penton was spun-off in 1998 as well as input from our
pension fund consultant and our actuarial consultant on asset class return and
long-term inflation rate expectations.

RETIREMENT AND SAVINGS PLAN

     The Penton Media, Inc. Retirement and Savings Plan (the "RSP") is a 401(k)
contribution plan that covers substantially all domestic employees of the
Company. The RSP permits participants to defer up to a maximum of 25% of their
compensation. Beginning in 2004, the Company made monthly contributions to each
employee's retirement account equal to between 3% and 6% of the employee's
annual salary, based on age and years of service. Beginning in 2005, the Company
will make quarterly contributions to eligible employees who are employed on the
last day of the quarter equal to 3% of the employee's annual salary. The
Company's contributions become fully vested once the employee completes five
years of service. In 2004 the Company made total contributions of $1.7 million
to the RSP and expects to make contributions of approximately $1.6 million in
2005.

     For the years ended December 31, 2004, 2003 and 2002, the total rent
expense (including taxes, insurance and maintenance when included in the rent
payment) incurred by Penton was approximately $4.6 million, $5.1 million and
$6.7 million, respectively. In addition, rent expense classified as part of
restructuring and other charges in the consolidated statements of operations
were $2.2 million, $3.3 million and $2.3 million for the years ended 2004, 2003
and 2002, respectively.

LEGAL PROCEEDINGS

     On November 3, 2003, a lawsuit was brought against the Company for an
unspecified amount by Allison & Associates, Inc. under the Telephone Consumer
Protection Act ("TCPA"), which prohibits against the transmission of unsolicited
fax advertisements. The lawsuit is a punitive class action that seeks to
represent a class of plaintiffs comprised of all individuals and entities who,
during the period November 3, 1999, through the present, received one or more
facsimiles sent by or on behalf of the Company advertising the commercial
availability of its products or services and who did not give their prior
expressed permission or invitation to receive such faxes. The statutory penalty
for a single violation of the TCPA is $500, although the penalty can increase to
$1,500 per violation if the Company is found to have willfully or knowingly
violated these laws. The case is currently pending in the Richmond County,
Georgia, Superior Court, and the Company is complying with the Court's order for
discovery. A hearing on class certification is currently scheduled for May 3,
2005. The Company is uncertain as to the outcome of this case.

     In connection with the acquisition of Mecklermedia Corporation in 1998, a
lawsuit was brought against the Company on December 1, 1998 by Ariff Alidina
(the "Plaintiff"), a former stockholder of Mecklermedia Corporation, in the
United States Federal District Court in the Southern District of New York for an
unspecified amount, as well as other relief. The Plaintiff had 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 Jupitermedia Corporation for what the Plaintiff alleges was a below-
market price, thereby giving to Mr. Meckler more consideration for his common
stock in Mecklermedia Corporation than was paid to other stockholders of
Mecklermedia Corporation. On May 16, 2001, the United States District Court for
the Southern District of New York granted the Plaintiff's motion for
certification of a class consisting of all former stockholders of Mecklermedia
who tendered their shares in the tender offer. By letter dated November 3, 2003,
plaintiffs' counsel informed the Court that a settlement had been reached in the
case. In July 2004, the Federal District Court approved the settlement between
the former stockholders of Mecklermedia and the Company for $4.6 million. The
class settlement was paid entirely from insurance proceeds in August 2004. As
part of the settlement, the Company wrote off $0.8 million in related legal
fees, which are not expected to be reimbursed from the insurance carrier. This
amount was classified with restructuring and other expenses in the consolidated
statements of operations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In the normal course of business, Penton 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 Penton's financial statements, management is unable to estimate the
magnitude or financial impact of claims and lawsuits that may be filed in the
future.

TAX MATTERS

     The calculation of our tax liabilities involves dealing with uncertainties
in the application of complex tax regulations. We recognize liabilities for
anticipated tax audit issues based on our estimate of whether, and the extent to
which, additional taxes will be due. If we ultimately determine that payment of
these amounts is unnecessary, we reverse the liability and recognize a tax
benefit during the period in which we determine that the liability is no longer
necessary. We also recognize tax benefits to the extent that it is probable that
our positions will be sustained when challenged by the taxing authorities. As of
December 31, 2004 we had not recognized tax benefits of approximately $2.2
million relating to various state tax positions. Should the ultimate outcome be
unfavorable, we would be required to make a cash payment for all tax reductions
claimed as of that date.

CURRENT LIQUIDITY

     The Company believes that its existing sources of liquidity, along with
revenues expected to be generated from operations, will be sufficient to fund
operations, anticipated capital expenditures, working capital, and other
financing requirements. However, if the Company continues to incur operating
losses and negative cash flows in the future, Penton may need to further reduce
its operating costs or obtain alternate sources of financing, or both, to remain
viable. The Company's ability to meet cash operating requirements depends upon
its future performance, which is subject to general economic conditions and to
financial, competitive, business, and other factors. The Company's ability to
return to sustained profitability at acceptable levels will depend on a number
of risk factors, many of which are largely beyond the Company's control. If the
Company is unable to meet its debt obligations or fund its other liquidity
needs, particularly if the revenue environment deteriorates, Penton may be
required to raise additional capital through additional financing arrangements
or the issuance of private or public debt or equity securities. Such additional
financing may not be available at acceptable terms. In addition, the terms of
our convertible preferred stock and warrants issued, including the conversion
price, dividend and liquidation adjustment provisions could result in
substantial dilution to common stockholders. The redemption price premiums and
board representation rights could negatively impact our ability to access the
equity markets in the future.

OTHER COMMITMENTS

     At December 31, 2004, Penton had in place a print agreement with R.R.
Donnelley & Sons Company ("R.R. Donnelley"), which entitles R.R. Donnelley to
the exclusive right to print and produce certain magazines for a period of seven
years beginning December 1, 1999 through November 30, 2006. Under the agreement,
which is non-cancelable, Penton is obligated to pay certain minimum amounts.
These minimum amounts will be adjusted annually based on changes in the Consumer
Price Index.

     The following schedule sets forth the minimum liability under the agreement
with R.R. Donnelley as of December 31, 2004 (in thousands):

     Effective January 1, 2005, Penton and R.R. Donnelley replaced the print
agreement with a new seven-year agreement. See Note 23 -- Subsequent Events.

     The Company entered into a two-year agreement with Sprint in July 2002. The
agreement, which was amended in 2004, provides for annual minimum usage levels
by Penton of approximately $0.8 million each year.

NOTE 11 -- MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK

PREFERRED STOCK LEVERAGE RATIO EVENT OF NON-COMPLIANCE

     On September 13, 2004, the Company filed a Certificate of Designations
governing a new series of convertible preferred stock, $0.01 par value (the
"Series C Preferred") with the Secretary of State for the State of Delaware. The
Series C Preferred stock was exchanged on a share-for-share basis with the
Company's Series B Convertible Preferred Stock, $0.01 par value (the "Series B
Preferred"). The Certificate of Designations for the Series C Preferred stock is
identical to the Series B Preferred stock Certificate of Designations except:

     - The new series allows for the sharing of the liquidation preference with
       the new Series M Preferred stock (discussed below);

     - Certain technical and correcting amendments have been made to the
       Certificate of Designations for the Series C Preferred stock, including
       fixing the formula used to calculate the "Change of Control Cap" (as
       defined in the Series C Preferred stock Certificate of Designations); and

     - Certain conforming changes were made to the Series C Preferred stock
       Certificate of Designations to account for the fact that the Series C
       Preferred stock was issued in exchange for the Series B Preferred stock.

     At December 31, 2004, an event of non-compliance continues to exist under
our Series C Preferred stock because the Company's leverage ratio of 11.8
(defined as debt less cash balances in excess of $5.0 million plus the
liquidation value of the convertible preferred stock and unpaid dividends
divided by adjusted EBITDA) exceeds 7.5. Upon the occurrence of this event of
non-compliance, the 5% per annum dividend rate on the preferred stock increased
by one percentage point as of April 1, June 30, September 28 and December 27,
2003 and March 26, 2004 to the current maximum rate of 10% per annum. The
dividend rate will adjust back to 5% as of the date on which the leverage ratio
is less than 7.5. The leverage ratio event of non-compliance does not represent
an event of default or violation under any of the Company's outstanding notes or
the loan agreement. As such, there is no acceleration of any outstanding
indebtedness as a result of this event. In addition, this event of
non-compliance and the resulting consequences have not resulted in any cash
outflow from the Company.

     If the Company had been sold on December 31, 2004, the bondholders would
have been entitled to receive $335.8 million and the Series C Preferred
stockholders would have been entitled to receive $122.5 million before the
common stockholders would have received any amounts for their common shares. The
amount the Series C Preferred stockholders would be entitled to receive could
increase significantly in the future under certain circumstances. Common
stockholders are urged to read the terms of the Series C Preferred stock
agreement carefully.

     Under the conversion terms of the preferred stock, each holder has a right
to convert dividends into additional shares of common stock. At December 31,
2004, no dividends have been declared. However, in light of each holder's
conversion right and considering the increase in the dividend rate and the
concurrent reduction of the conversion price as noted above, the Company has
recognized a deemed dividend for the beneficial conversion feature inherent in
the accumulated dividend based on the original commitment date(s). At December
31, 2004, 2003 and 2002, $12.2 million, $8.5 million and $4.3 million,
respectively have been

ISSUANCE OF MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK AND WARRANTS

     On March 19, 2002, the Company issued 40,000 shares of Series B Preferred

1,280,000 shares of Penton's common stock, par value $0.01 per share, for $40.0
million in a private placement to institutional investors and affiliated
entities. On March 28, 2002, the Company issued an additional 10,000 shares of
Series B Preferred stock, par value $0.01 per share, and warrants to purchase an
additional 320,000 shares of Penton's common stock, par value $0.01 per share,
for $10.0 million to the same group of investors. The net proceeds from the sale
of the Series B Preferred stock and warrants were used to repay the term loan
indebtedness outstanding under Penton's senior credit facility.

     The net proceeds of $46.2 million from the issuance of the convertible
preferred stock and warrants, net of issuance costs of $3.8 million, were
allocated to the convertible preferred stock and warrants based on the relative
fair values of each security as of the respective commitment dates noted above.
Approximately $4.1 million of the net proceeds were allocated to the warrants
and were recorded in capital in excess of par value, resulting in a discount to
the convertible preferred stock. The fair value of the warrants was determined
using the Black-Scholes pricing model.

     The balance of the net proceeds of approximately $42.1 million was
allocated to the convertible preferred stock, which, because of the mandatory
redemption date and other redemption provisions, was classified outside of
permanent equity. Pursuant to the provisions of EITF 98-5, "Accounting for
Convertible Securities with Beneficial Conversion Features or Contingently
Adjustable Conversion Ratios," ("EITF 98-5") and EITF 00-27, "Application of
Issue 98-5 to Certain Convertible Instruments," ("EITF 00-27") the entire amount
of $42.1 million was initially recorded as a beneficial conversion feature in
capital in excess of par value, resulting in an additional discount to the
convertible preferred stock. The amount of the beneficial conversion feature was
determined pursuant to Issue 2 of EITF 00-27. As such, the most beneficial
"accounting conversion price" at the issue date of the preferred shares was
compared with the closing market price of the stock on that date, and the
intrinsic spread was multiplied by the number of most beneficial shares into
which the preferred shares can be converted. This beneficial conversion feature
was being recognized, using the interest method, as a deemed dividend to the
preferred stockholders and an increase in the carrying value of the preferred
stock from the issuance date to the 10-year mandatory redemption date.

     The preferred stock was also initially being accreted to its maximum
redemption amount possible pursuant to Topic D-98, "Classification and
Measurement of Redeemable Securities," using the interest method from the
issuance date to the 10-year mandatory redemption date.

     In April 2002, the Company reached an agreement with the preferred
stockholders to eliminate the scheduled 10-year redemption date of the preferred
stock, and on May 31, 2002, the Company's common stockholders approved an
amendment to remove the scheduled redemption feature. In exchange for removing
the scheduled redemption date, the Company agreed to grant the holders of the
preferred stock the right to require Penton to seek a buyer for substantially
all of its assets or issued and outstanding capital stock beginning on March 19,
2008, if any preferred stock remains outstanding. The Company sought the
amendment to eliminate the requirement to accrete the preferred stock to the
maximum possible redemption amount by such date. However, it did not seek to
eliminate the preferred stockholders' right to require the Company to redeem the
security upon the occurrence of certain contingent events, including a change in
control or liquidation, dissolution or winding-up of Penton. To the extent that
redemption of the preferred stock becomes probable in the future pursuant to a
contingent redemption provision of the preferred stock, accretion to the maximum
redemption amount will be required at such time.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Prior to the stockholder approval to remove the scheduled redemption date,
the Company was required to accrete a portion of the maximum redemption amount.
Accordingly, approximately $2.5 million was accreted, using the interest method,
prior to May 31, 2002. In addition, certain features of the preferred stock had
to be accounted for as embedded derivatives, which required mark-to-market
accounting that could have potentially resulted in significant swings in net
income and earnings per share. The preferred shares agreement has a number of
conversion and redemption provisions that represented derivatives under SFAS 133
prior to the elimination of the mandatory redemption date. The Company
determined that certain of these derivatives do not qualify for scope exemption
and are not clearly and closely related to the host contract. As such, these
embedded derivatives were required to be bifurcated and recorded at fair value.
The fair values of these derivatives were calculated using the Black-Scholes
pricing model.

     As a result of stockholder approval on May 31, 2002, accretion was no
longer required and the $42.1 million of unamortized beneficial conversion
feature was recognized immediately as a charge to capital in excess of par and
as a reduction of income available to common stockholders in the consolidated
statements of operations. In addition, mark-to-market accounting for the
embedded derivatives was no longer required subsequent to May 31, 2002. Pursuant
to SFAS 133, the elimination of the mandatory redemption feature made the
preferred shares agreement more akin to an equity instrument than a debt
instrument. Consequently, the embedded derivatives noted above, which related to
the conversion or redemption options, either qualified for a scope exemption or
did not constitute derivatives pursuant to SFAS 133. Therefore, the elimination
of the mandatory redemption feature also eliminated the requirement to
mark-to-market these derivatives.

     The elimination of the mandatory redemption date does not alter the
mezzanine classification of the preferred shares in the consolidated balance
sheets because of the existence of other redemption provisions in the preferred
shares agreement, such as the optional redemption by the holders of the
preferred shares in the event of a change in control. Dividends on the preferred
stock will continue to be accrued and will be reflected as a reduction in
earnings applicable to common stockholders.

SUMMARY OF TERMS OF CONVERTIBLE PREFERRED STOCK

     Below is a description of the material terms of the preferred stock and
warrants reflecting the effects of the stockholder approval of the transaction
and the elimination of the mandatory redemption date discussed above.

Liquidation Preference

     The preferred stock has preferences over the common stock in the event of
liquidation or change in control, dissolution or winding-up. Upon the occurrence
of any such event, the preferred stockholders will be entitled to be paid in
cash, subject to the satisfaction of Penton's obligations under the indentures
governing the Company's Subordinated Notes and Secured Notes.

     The initial liquidation value of the preferred stock is $1,000 per share.
If the preferred stock is not converted or redeemed prior to March 19, 2008, the
liquidation value will increase to $4,570 per share. The liquidation preference
is the liquidation value plus accrued and unpaid dividends.

Dividends

     From the date of issuance until March 19, 2008, the dividends on the
preferred stock accrues daily on the sum of the then-applicable liquidation
preference and the accrued dividends thereon. Initially the annual rate was 5%
per annum. However, upon the occurrence of certain triggering events, the
dividend rate increases by one percentage point, with additional
one-percentage-point increases every ninety days up to a maximum increase of
five percentage points. One of those triggering events is a leverage ratio event
of non-compliance. As noted above, a leverage ratio event of non-compliance
initially occurred on April 1, 2003 and continues to

                                        99

                               PENTON MEDIA, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

exist as of the date of this filing. Consequently, the dividend rate is
currently 10%. The dividend rate will adjust back to 5% (to the extent of any
preferred shares still outstanding) once the leverage ratio is less than 7.5.

     From and after March 19, 2008, the dividends will accrue at a rate of 15%
per annum. Preferred dividends of $11.4 million were accrued at December 31,
2004.

     Dividends are payable semiannually in cash only if declared by Penton's
Board of Directors and approved by holders of no less than 75% of the preferred
stock then outstanding. The provisions of Penton's notes limit its ability to
pay dividends in cash, and the Company has no present intention to either
declare or pay cash dividends on the preferred stock.

Conversion Provisions

     Each share of preferred stock is convertible into common stock at each
holder's option and, subject to certain restrictions, at Penton's option.
Preferred stock is convertible into Penton common stock by multiplying the
number of shares of preferred stock to be converted by the liquidation value
plus accrued and unpaid dividends divided by the conversion price. The
conversion price for the preferred stock is $7.61 per share, subject to certain
anti-dilution adjustments. Among others, the restrictions on Penton's right to
force conversion include the market price of the common shares being equal to or
greater than the applicable share minimum noted below.

Company's Redemption Provisions

     The Company can redeem the preferred stock at any time, in whole or in
part, at a cash redemption price equal to the product of the number of shares of
common stock into which the preferred shares can be converted and the greater of
the volume weighted-average closing share price of Penton's common stock for the
preceding 30 trading days or the applicable minimum share price derived from the
following schedule (as may be adjusted for stock splits and similar
transactions):

<Table>
<S>                                                            <C>
If being redeemed prior to the third anniversary............   $15.18
If being redeemed after the third, but before the fourth
  anniversary...............................................   $17.51
If being redeemed after the fourth, but before the fifth
  anniversary...............................................   $19.31
If being redeemed after the fifth, but before the sixth
  anniversary...............................................   $23.26
</Table>

Holders' Redemption Provisions

     The preferred stockholders have the right to require the Company to redeem
the security upon the occurrence of certain contingent events, including a
change in control or liquidation, dissolution or winding-up of Penton.

Conversion Prices

     The initial conversion price is $7.61 per share (subject to certain
anti-dilution adjustments) until the sixth anniversary of issuance, at which
time the price may be adjusted to the lesser of (a) the conversion price in
effect on the sixth anniversary or (b) the greater of 90% of the market price of
the Company's common stock on the conversion date or $4.50.

     If Penton fails to comply with specific covenants contained in the purchase
agreement, the conversion price of the preferred stock will be reduced by $0.76
(adjusted for stock splits and similar transactions) until such failure is no
longer in existence, and every 90 days thereafter, the conversion price shall be
reduced by an additional $0.76 up to a maximum reduction of $3.80 (adjusted for
stock splits and similar transactions). The conversion price will adjust to what
it would have been absent such breach (to the extent of any shares of preferred
stock still outstanding) once the breach is cured. No such reduction to the
conversion price will be

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

made at any time that representatives of the investors constitute a majority of
the Board of Directors. In addition, if Penton's leverage ratio, as previously
defined, exceeds 7.5 to 1.0 for any quarterly period beginning on December 31,
2002, and such leverage ratio remains in excess of 7.5 to 1.0 for a period of 90
days, the conversion price of the preferred stock will be reduced by $0.76
(adjusted for stock splits and similar transactions). The conversion price will
be reduced by another $0.76 (adjusted for stock splits and similar
transactions), subject to a maximum reduction not to exceed $3.80 (adjusted for
stock splits and similar transactions) every 90 days until the leverage ratio is
less than 7.5 to 1.0. The conversion price will adjust to what it would have
been absent such event (to the extent of any shares of preferred stock still
outstanding) once the leverage ratio is less than 7.5 to 1.0. No such reduction
to the conversion price will be made at any time that representatives of the
investors constitute a majority of the Board of Directors.

Board Representation

     The preferred stockholders were initially entitled to three Board seats.
When the leverage ratio event of non-compliance first occurred on April 1, 2003,
the holders of a majority of the preferred stock were able to nominate two
additional members to our Board of Directors. Since the event of non-compliance
was not cured by June 30, 2003, the holders of a majority of the preferred stock
then outstanding had the right to elect one less than a minimum majority of our
Board of Directors. As the holders of the preferred stock already maintained one
less than a minimum majority of our Board, no change was necessary. In July
2004, at the Company's annual stockholders' meeting, changes were made to its
Board of Directors such that the preferred stockholders now constitute a
majority of the Board.

     At such time as the holders of preferred stock cease to hold shares of
preferred stock having an aggregate liquidation preference of at least $25.0
million, they will lose the right to appoint the director for one of these Board
seats. On March 19, 2008, the holders of a majority of the preferred stock then
outstanding, if any, will be entitled to appoint one less than a minimum
majority of the Board of Directors. In addition, if the Company initiates or
consents to proceedings under any applicable bankruptcy, insolvency,
composition, or other similar laws, the holders of a majority of the preferred
stock may appoint a minimum majority of Penton's Board of Directors. At such
time as the holders of preferred stock cease to hold shares of preferred stock
having an aggregate liquidation preference of at least $10.0 million, and such
holders' beneficial ownership of Penton's preferred stock and common stock
constitutes less than 5% of the aggregate voting power of the Company's voting
securities, the holders of preferred stock will no longer have the right to
appoint any directors to the Board of Directors.

     Penton has also granted the holders of the preferred stock the right to
have representatives attend meetings of the Board of Directors after such time
as they are no longer entitled to appoint any members to the Board of Directors
and until such time as they no longer own any preferred stock, warrants or
shares of common stock issued upon conversion of the preferred stock or exercise
of the warrants.

Voting Rights

     The holders of the preferred stock are entitled to vote on all matters
submitted to a vote of Penton's stockholders, voting as a single class with the
common stockholders on an as-converted basis. In addition, Penton may not,
without the affirmative vote of the holders of not less than 75% of the
preferred stock then outstanding, declare and pay dividends, impact the existing
classes of capital stock or increase the size of the Board, among other
conditions.

Covenants

     The terms of the preferred stock have several financial and non-financial
covenants. As of December 31, 2004, Penton was in compliance with all such
covenants, except the preferred stock leverage ratio, as discussed above.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Sales Rights

     The terms of the preferred stock require that Penton maintain a leverage
ratio, as previously defined, of 7.5 to 1.0 for the twelve month period ending
on the last day of December, March, June, and September of each year beginning
with the period ending on December 31, 2002. If Penton is not in compliance with
this covenant for four consecutive fiscal quarters, then the holders of a
majority of the preferred stock have the right to cause the Company to seek a
buyer for all of its assets or all of its issued and outstanding capital stock.
As discussed previously, as of December 31, 2004, the leverage ratio has
exceeded 7.5 for four consecutive quarters and the preferred stockholders have
the right to cause the Company to seek a buyer for all of the assets or the
issued and outstanding capital stock of the Company.

     In exchange for removing the scheduled redemption date, as approved at the
2002 annual stockholders' meeting, as discussed above, the Company agreed to
grant the holders of the preferred stock the right to require the Company to
seek a buyer for substantially all of its assets or issued and outstanding
capital stock beginning on March 19, 2008. The holders of the preferred stock
will not have this right if less than 3,500 shares of preferred stock (as
adjusted for stock splits and similar transactions) are then outstanding.

Warrants

     The initial exercise price of the warrants was $7.61 per share. The
warrants are subject to anti-dilution and other adjustments that mirror those
applicable to the preferred stock. The warrants are immediately exercisable and
expire 10 years after issuance.

SERIES M PREFERRED STOCK

     In September 2004, the Company filed a Certificate of Designations for a
new series of preferred stock, $0.01 par value (the "Series M Preferred") with
the Secretary of State for the State of Delaware. The Board of Directors of the
Company created the Series M Preferred stock for issuance to certain officers
and other key employees of the Company as a long-term incentive plan for
management by giving them an equity stake in the performance of the Company. The
Series M Preferred stock is limited to 150,000 shares of which 68,625 shares
were issued as of December 31, 2004. The Series M Preferred stock is treated
under fixed plan accounting and is classified in the mezzanine section of the
consolidated balance sheets because redemption is outside the control of the
Company. The Company recognized an immaterial amount of expense related to the
Series M Preferred in 2004.

     Among other rights and provisions, the Series M Preferred provides that the
holder of each share will receive a cash distribution upon any liquidation,
dissolution, winding-up or change of control of the Company. The amount of such
distribution is first a percentage of what the holders of Series C Preferred
stock and second a percentage of what the holders of the Company's common stock
would receive upon such liquidation, dissolution, winding-up or change of
control.

NOTE 12 -- COMMON STOCK AND COMMON STOCK AWARD PROGRAMS

BOARD OF DIRECTOR CHANGES

     Effective at the annual meeting of stockholders on July 15, 2004, the
number of board members decreased from eleven to eight. Furthermore, at the
Company's Board of Directors meeting held on July 21, 2004, the Board named Mr.
Nussbaum as a director and decreased the number of directors from eight to
seven.

EQUITY AND PERFORMANCE INCENTIVE PLAN

     There are 5,500,000 shares of common stock reserved for issuance under the
Company's 1998 Equity and Performance Incentive Plan.

  Stock Options

     The Company has stock option plans under which employees and directors may
be granted options to purchase shares of the Company's common stock. Options
granted under the plans generally vest equally over three years from the date of
grant. However, most options granted are not exercisable until the third
anniversary. All options granted pursuant to the plans expire no later than 10
years from the date the option was granted.

     At December 31, 2004, a total of 1,432,675 options are outstanding. In 2004
and 2003, employees exercised 17,000 and 30,249 options, respectively. No
options were exercised in 2002.

     In February 2004, 473,700 options were granted to certain executives and
other eligible employees at an exercise price of $0.90 per share. No
compensation expense was recorded by the Company as a result of this grant.

     In July 2002, Penton filed a tender offer for eligible employees who had
options outstanding with exercise prices greater than or equal to $16.225 per
share. The offer to exchange options expired on August 22, 2002, at which time
860,100 options, out of a total of 917,600 eligible options, had been cancelled.
In February 2003, 334,850 new options were granted at an exercise price of $0.37
per share. No compensation expense was recorded by the Company as a result of
the tender offer. The following table presents a summary of Penton's stock
option activity and related information for the years ended 2002, 2003 and 2004

     In February 2004, 445,000 deferred shares were granted to certain
executives and in June 2004, the Board granted 514,706 deferred shares to one
executive. Furthermore, in June 2004, the Board accelerated the vesting of
345,000 deferred shares originally granted in February 2004 to two executives.
At December 31, 2004, 614,706 deferred shares are outstanding. Of these shares,
100,000 shares vest one-fourth on each three-month anniversary following the
date of grant, and 514,706 shares vested on January 3, 2005. During 2004,
587,785 deferred shares were issued for Penton common stock under this plan, of
which, 292,271 deferred shares were returned to the Company by executives to
cover the taxes related to the issuance of these shares and to pay down a
portion of an executive loan.

     Compensation expense is being recognized over the related vesting period
based on the fair value of the shares at the date of grant. During 2004, 2003
and 2002, approximately $0.6 million, $1.4 million and $4.3 million,
respectively, were charged to expense under this plan. The Board of Directors
may authorize the payment of dividend equivalents on such shares on a current,
deferred or contingent basis, either in cash or in additional shares of common
stock. At December 31, 2004, no such authorization has been made.

  Performance Shares

     In 2004, the Company issued common stock related to 11,250 performance
shares, which were earned as of December 31, 2003. Furthermore, a total 255,000
performance shares were immediately vested in accordance with the respective
performance share agreements when the employment of three executives was
terminated in June 2004. These shares were issued in July 2004. At December 31,
2004, no performance shares are outstanding.

     Performance shares are generally not issuable until earned. Compensation
expense related to these shares is recorded over the performance period. For the
year ended December 31, 2004, $0.1 million was charged to expense for this plan.
For the years ended December 31, 2003 and 2002, an immaterial amount and $1.4
million, respectively, was credited to expense. These credits resulted from the
decrease in the Company's stock price.

REDEEMABLE COMMON STOCK

     At December 31, 2003, the Company classified 4,191 common shares outside of
stockholders' deficit because the redemption of the stock was not within the
control of the Company. Redeemable common stock relates to common stock that may
be subject to rescissionary rights. The purchase of common stock by certain

employees in the Company's 401(k) plan from May 2001 through March 2003 was not
registered under the federal securities laws. As a result, such purchasers of
our common stock during that period may have had the right to rescind their
purchases for an amount equal to the purchase price paid for the shares, plus
interest from the date of purchase. On March 14, 2004, all rescissionary rights
expired.

EMPLOYEE STOCK PURCHASE PLAN

     In 2004, the Company terminated its Employee Stock Purchase Plan. The plan
allowed employees the opportunity to purchase shares of Penton common stock at
85% of the lower of the market price at the beginning or end of each quarter.
This plan was deemed to be non-compensatory. Employees purchased 65,711 shares
and 542,450 shares in 2003 and 2002, respectively. No shares were purchased in
2004.

MANAGEMENT STOCK PURCHASE PLAN

     The Company has a Management Stock Purchase Plan ("MSPP") for designated
officers and other key employees. Participants in the plan may elect to receive
restricted stock units ("RSUs") in lieu of a designated portion of up to 100% of
their annual incentive bonus. Each RSU represents the right to receive one share
of Penton common stock. RSUs are granted at a 20% discount from fair market
value on the date awarded. RSUs vest two years after the date of grant and are
settled in shares of common stock after a period of deferral (of no less than
two years) selected by the participant, or upon termination of employment. The
discount is recorded as compensation expense over the minimum vesting period.
The amounts of expense recognized for the years 2004, 2003 and 2002 were not
material.

     In February 2004, a total of 595 RSUs were granted at $0.84 per share. At
December 31, 2004, 2003 and 2002, 79,424, 106,392 and 56,079 RSUs were
outstanding, respectively. During 2004, 2003 and 2002, the Company issued 24,611
shares, 35,850 shares and 17,472 shares, respectively, of common stock under
this plan.

EXECUTIVE LOAN PROGRAM

     In 2000, the Company established an Executive Loan Program, which allowed
Penton to issue shares of Company common stock at fair market value to six key
executives, in exchange for full recourse notes. In December 2001, the loan
notes were amended to cease interest charges as well as to extend the maturity
date from the fifth anniversary of the first loan date to six months following
the seventh anniversary of the first loan date. No payments are required until
maturity, at which time all outstanding amounts are due.

     In June 2004, Mr. Nussbaum repaid his outstanding loan balance with
proceeds from his signing bonus and 288,710 shares of Penton common stock, which
were returned to the Company. In addition, the Board agreed to discharge the
outstanding balance due on Mr. Ramella's executive loan in exchange for Mr.
Ramella releasing the Company of any claims he may have had. The Board also
agreed upon a number of provisions related to Mr. Kemp's outstanding executive
loan balance. See Note 15 -- Executive Bonus and Termination Benefits for a
detailed discussion of events related to the above transactions.

     EITF 00-23, "Issues Related to the Accounting for Stock Compensation under
APB Opinion No. 25 and FASB Interpretation No. 44" ("EITF 00-23") requires that
when a Company forgives all or part of a recourse note it must consider all
other existing recourse notes as nonrecourse prospectively (variable
accounting). Consequently, the Company recognized $0.1 million in additional
paid in capital in excess of par equal to the fair market value of the stock
issued in conjunction with the establishment of the loans. In addition, the
Company recorded a $1.8 million provision for loan impairment on the remaining
unreserved loan balance in 2004. Additionally, the Company reversed the $1.1
million reserve established in June 2003 related to Mr. Nussbaum's loan note
against his signing bonus of $1.7 million, which was recorded in selling,
general and administrative expenses on the consolidated statements of
operations. In the future, all awards exercised with

recourse notes shall be presumed to be exercised with nonrecourse notes with any
dividends recorded as compensation expense and interest recorded as part of the
exercise price.

     At December 31, 2004 and 2003, the outstanding loan balance due under the
Executive Loan Program was approximately $5.8 million and $9.5 million,
respectively. The loan balance, net of amounts reserved of $5.8 million and $7.6
million at December 31, 2004 and 2003, respectively, is classified in the
stockholders' deficit section of the consolidated balance sheets as notes
receivable from officers.

PERFORMANCE UNITS

     In 2003, the Company granted 490,155 performance units to certain key
executives. Subject to the attainment of certain performance goals over a
three-year period from January 1, 2003 through December 31, 2005, each grantee
can earn a cash award in respect to each performance unit. In 2004 and 2003,
approximately $0.5 million and $0.2 million, respectively, was recognized as
expense. A total of 195,012 performance units worth $0.4 million were
immediately vested in accordance with their respective performance share
agreements when the employment of two executives was terminated in June 2004.
These amounts were paid in July 2004.

TREASURY STOCK

     In 2004 and 2003, five executives returned 157,271 shares and 89,214
shares, respectively, to the Company to cover taxes for deferred shares issued
during the year. In addition, in 2004, one executive returned 288,710 shares
valued at $0.1 million, to pay down a portion of his executive loan balance. In
2003, the Company issued 19,050 shares of treasury stock to employees under the
management stock purchase plan.

     Treasury stock is purchased for constructive retirement and is carried at
cost and recorded as a net decrease in capital in excess of par value.

     Our preferred stock and RSUs are participating securities, such that in the
event a dividend is declared or paid on the common stock, the Company must
simultaneously declare and pay a dividend on the preferred stock and the RSUs as
if the preferred stock and the RSUs had been converted into common stock. EITF
03-6 requires that participating securities included in the scope of EITF 03-6
be included in the computation of basic earnings per share if the effect of
inclusion is dilutive. Vested RSUs and vested deferred shares are always
included in the computation of basic earnings per share as they are considered
equivalent to common stock. For participating securities included in the scope
of EITF 03-6, the use of the two-class method to determine whether the inclusion
of such securities is dilutive is required. Furthermore, non-vested RSUs are
included in basic EPS using the two-class method in accordance with SFAS 128. To
the extent not included in basic earnings per share, the redeemable preferred
stock and the non-vested RSUs are considered in the diluted earnings per share
calculation under the "if-converted" method and "treasury stock" method,
respectively. At December 31, 2004, 2003 and 2002, redeemable preferred stock
and non-vested RSUs were excluded from the calculation of basic earnings per
share as the results were anti-dilutive.

     Due to the net loss applicable to common stockholders in 2004, 1,432,675
stock options, 115,000 performance shares, 539,706 non-vested deferred shares,
73,695 non-vested RSUs and 1,600,000 warrants were excluded from the calculation
of diluted earnings per share as the result would have been anti-dilutive. Due
to the net loss applicable to common stockholders in 2003, 1,911,280 stock
options, 381,250 performance shares, 99,579 non-vested deferred shares, 100,696
non-vested RSUs, and 1,600,000 warrants were excluded from the calculation of
diluted earnings per share as the result would have been anti-dilutive. Due to
the net loss applicable to common stockholders in 2002, 1,597,355 stock options,
603,003 performance shares, 234,542 non-vested deferred shares, 47,677
non-vested RSUs and 1,600,000 warrants were excluded from the calculation of

NOTE 15 -- EXECUTIVE BONUS AND TERMINATION BENEFITS

     In June 2004, Penton's Board of Directors announced the appointment of
David B. Nussbaum as Chief Executive Officer ("CEO") of the Company. In addition
to the Company's standard executive incentive and benefit package, Mr. Nussbaum
received a signing bonus of approximately $1.7 million and 30,000 shares of the
new Series M Preferred Stock. The Board also accelerated the vesting of 135,000
deferred shares granted to Mr. Nussbaum in February 2004. Mr. Nussbaum used the
net proceeds from his signing bonus and 288,710 shares of Penton common stock,
which were returned to the Company, to repay his executive loan balance in full.

     In March 2004, the Company announced that its Chairman and CEO, Thomas L.
Kemp, would be leaving the Company. Mr. Kemp's employment was terminated
effective June 30, 2004, and on July 1, 2004, Mr. Kemp and the Company signed a
Separation Agreement and General Release agreement. The separation agreement
stipulated a lump-sum payment of $2.3 million (including the settlement of Mr.
Kemp's accrued SERP obligation of $0.2 million), the acceleration of 100,000
stock options, and the acceleration of 125,000 performance shares.

     In addition, the Board and Mr. Kemp agreed upon a number of provisions
related to Mr. Kemp's outstanding executive loan balance. The underlying goal of
these provisions is to ensure that there are sufficient funds available to pay
any amount due to taxing authorities in case the loan is discharged at a future
date. Specifically, $0.8 million of the $2.3 million lump-sum payment has been
placed in escrow and will be returned to Mr. Kemp only if he pays off the entire
loan balance by its due date. Furthermore, Mr. Kemp has granted Penton a
security interest in approximately 1.1 million shares of Penton common stock.
These pledged securities could be transferred to Penton's ownership under
certain circumstances and the proceeds used to pay down the outstanding loan
balance.

     Furthermore, in June 2004, Mr. Kemp was granted 514,706 deferred shares
that vested on January 3, 2005. In return for these shares, Mr. Kemp agreed to
comply with the terms of certain restrictive covenants, including a non-compete
and a non-solicitation covenant. See Note 23 -- Subsequent Events.

     In June 2004, the Company announced that its President and Chief Operating
Officer, Daniel J. Ramella, would be leaving the Company as part of a management
restructuring plan. Mr. Ramella's employment was terminated effective June 30,
2004, and on July 1, 2004, Mr. Ramella and the Company signed a Separation
Agreement and General Release agreement. The separation agreement stipulated a
lump-sum payment of $1.7 million (including the settlement of Mr. Ramella's
accrued SERP obligation of $0.2 million), and the acceleration of 139,999 stock
options, 210,000 deferred shares and 90,000 performance shares. In addition, the
Board agreed to discharge the $2.6 million outstanding balance on Mr. Ramella's
executive loan in return for full and final settlement of any claims Mr. Ramella
might have against the Company.

NOTE 16 -- BUSINESS RESTRUCTURING CHARGES

     Since 2001, the Company implemented a number of cost reduction initiatives
to improve its operating cost structure. The cost reduction initiatives included
workforce reductions, the consolidation and closure of over 30 facilities, and
the cancellation of various contracts. The costs associated with restructuring
activities are included in restructuring and other charges in the consolidated
statements of operations.

     The Company is actively attempting to sublease all vacant facilities. For
facilities that the Company no longer occupies and which have not yet been
subleased, management makes assumptions to estimate sublease income, including
the number of years a property will be subleased, square footage, market trends,
property location and the price per square foot based on discussions with
realtors and/or parties that have shown interest in the space. The Company
records estimated sublease income as a credit to restructuring and other charges
in the consolidated statements of operations.

2001 RESTRUCTURING PLAN

     In 2001, as part of a broad cost reduction initiative, the Company
announced certain expense reduction initiatives, including a reduction in
workforce of approximately 400 employees, the closure of more than 20 offices
worldwide and other exit costs primarily related to the write-off of
computerized software development costs. Adjustments to other exit costs of
approximately $1.0 million in 2001 primarily relate to the reversal of certain
restructuring initiatives that did not require the level of spending that had
originally been estimated. Adjustments to the 2001 Plan in 2002 and 2003 of $0.6
million and $0.3 million, respectively, were made to facility closing costs to
reflect changes in sublease assumption.

     Activity and liability balances related to the 2001 restructuring plan are

     The Company completed payments related to the reduction in workforce and
other exit cost in 2003. The Company expects to pay the obligations for the
non-cancelable leases over their respective lease terms, which expire at various
dates through 2013.

2002 RESTRUCTURING PLAN

     In 2002, the Company announced a number of expense reduction and
restructuring initiatives intended to further improve its operating cost
structure. The actions included costs of $5.1 million related to the closure of
nine additional offices worldwide. These amounts were offset in part by
approximately $1.7 million related to our New York, NY and Burlingame, CA
offices that were subleased in 2002. In addition, the Company reduced the
workforce by approximately 316 employees and recorded a liability for other
contractual obligations related primarily to the cancellation of trade show
venues, hotel contracts and service agreements. Facility closing cost
adjustments of $1.7 million in 2002 relate primarily to rent escalation
provisions, which had not been taken into consideration when the original 2002
liability was recorded. Adjustments to the 2002 plan in 2003 and 2004 of $0.6
million and $0.3 million, respectively, were made to facility closing costs to
reflect changes in sublease assumption.

2003 RESTRUCTURING PLAN

     In order to meet continued revenue challenges in 2003, the Company
implemented a number of additional expense reduction and restructuring
activities totaling $4.9 million, net of estimated sublease income. The
following sets forth additional detail concerning the principal components of
this charge:

        - Personnel costs of $2.7 million (as restated) are associated with the
          elimination of 85 positions. Approximately 91% of the positions
          eliminated were in the United States, with most of the remaining
          positions in the United Kingdom.

        - The Company recorded office closure costs of $3.8 million primarily
          related to the closure of one floor at the Company's corporate
          headquarters and the partial closure of one additional facility. This
          charge was offset by $2.3 million of estimated sublease income related
          to these facilities.

        - The charge for other exit costs of $0.7 million relates primarily to
          equipment lease payments at closed office facilities, cancellation of
          certain contracts and broker commissions.

NOTE 17 -- RELATED PARTY TRANSACTIONS

     The Company has an Executive Loan Program, which allowed Penton to issue
shares of Company common stock at fair market value to six key executives, in
exchange for full recourse notes. At December 31, 2004 and 2003, the outstanding
loan balance under the Executive Loan Program was approximately $5.8 million and
$9.5 million, respectively. In 2004 and 2003, executive loans of $1.0 million

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In December 2003, the Company entered into an agreement with a former
employee to provide trade show and conference services to select Penton events
in 2004 and 2005. In 2004, the Company paid $0.4 million under this agreement.
Effective December 31, 2004, the Company cancelled the agreement, resulting in
approximately $0.2 million of cancellation fees to be paid in 2005. This amount
is included in restructuring and other charges in the consolidated statements of
operations as of December 31, 2004.

     At December 31, 2003, Neue Medien owed PM Germany, a consolidated
subsidiary, $0.5 million. This amount is classified as notes receivable in the
consolidated balance sheets. Neue Median and Penton jointly own PM Germany. The
notes are due on demand and bear interest at the German Federal rate plus 3%, or
4.22% at December 31, 2003. As noted above, in December 2004, Penton sold 70% of
its interest in PM Germany to Neue Medien. See Note 3 -- Disposals.

     In January 2003, the Company sold its PTS group assets to Cygnus
Expositions, a division of Cygnus Business Media, Inc., a Delaware corporation,
for $3.2 million. Cygnus Business Media, Inc. is owned by ABRY Mezzanine
Partners L.P., which holds a significant portion of our Series C Preferred stock
and has two members on the Company's Board of Directors.

NOTE 18 -- SEGMENT INFORMATION

     Penton designates its operating segments based on how the chief operating
decision maker reviews the Company's performance. As the Company's new CEO, Mr.
Nussbaum, along with his executive team assess and manage the Company's
operations differently than the prior management team resulting in a change in
the Company's reportable segments effective in the third quarter of 2004. As a
result of this change in reportable segments, all prior periods were recast to
conform with the new segment format.

     The Company's newly designated segments include: Industry, Technology,
Lifestyle, Retail and International. The results of these newly established
segments will, consistent with past practice, be regularly reviewed by the
Company's chief operating decision maker and the executive team to determine how
resources will be allocated to each segment and to assess the performance of
each segment. All five segments derive their revenues from publications, trade
shows and conferences, and online media products. The segments are generally
based on the market sectors they serve, except the International segment, which
is primarily based on the geographical markets it serves.

     Content of each of our segment publications, trade shows and conferences,
and online media products is geared to customers in the following market sectors
and geographic markets (International):

NOTE 20 -- FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following methods and assumptions were used by the Company in
estimating fair value of financial instruments as of December 31, 2004 and 2003:

CASH AND CASH EQUIVALENTS, RESTRICTED CASH, ACCOUNTS RECEIVABLE, NOTES
RECEIVABLE, ACCOUNTS PAYABLE AND ACCRUED EXPENSES

     The carrying amounts reported in the consolidated balance sheets for cash
and cash equivalents, restricted cash, accounts and notes receivable, accounts
payable and accrued expenses approximated fair value because of their short
maturities.

SENIOR SECURED NOTES AND SENIOR SUBORDINATED NOTES

     The fair values of the Secured Notes and Subordinated Notes are determined
by reference to quoted market prices. At December 31, 2004 and 2003, the
Company's Secured Notes had fair values of $157.5 million and $153.0 million,
respectively, and carrying amounts of $157.0 million and $156.9 million,
respectively. At December 31, 2004 and 2003, the Company's Subordinated Notes
had fair values of $115.5 million and $116.8 million, respectively, and carrying

     Earnings per share calculations for each of the quarters are based on the
weighted-average number of shares outstanding for each quarter. The sum of the
quarters may not necessarily be equal to the full-year earnings per share
amounts.

     The increase in net loss, as restated, for the first, second and third
quarters of 2004 is due primarily to the additional income tax expense of $0.7
million, $0.7 million and $0.5 million, respectively, as a result of correcting
the Company's deferred taxes.

(a)  Includes $0.9 million restructuring charge and $2.4 million of executive
     separation costs.

(b)  Includes $3.5 million restructuring charge and $1.7 million provision for
     loan impairment.

(c)  Includes $1.5 million restructuring charge and $39.7 million related to
     impairment of assets.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 23 -- SUBSEQUENT EVENTS

     In February 2005, the Company replaced its printing agreement with R.R.
Donnelley dated December 1999 with a new seven-year agreement. The new agreement
expires on December 31, 2011 unless the a minimum revenue commitment to R.R.
Donnelley of $42.0 million is not reached at which time the agreement would
extend until the commitment is reached. The Company also agreed to consolidate
certain magazines under the new agreement when their current contract with other
vendors expired. In exchange, the Company will receive certain credits in 2005
and pricing reductions in 2006 through 2011. In addition the current purchase
commitments of $7.2 million and $6.8 million in 2005 and 2006 were eliminated.

     In the first quarter of 2005, the Company issued 614,706 deferred shares to
three executives, including 514,706 to a former executive. In addition, the
Company issued 69,775 shares in the first quarter of 2005 under the Company's
Management Stock Purchase Plan.

     In February 2005, the Company repurchased $5.5 million par value of its
10 3/8% senior subordinated notes for a total of $3.9 million, including $0.1
million of accrued interest, using excess cash on hand. The notes were purchased
in the open market and were trading at 69% of their par value at the time of
purchase. The repurchase resulted in a gain of approximately $1.6 million and
will reduce our annual interest charges by nearly $0.6 million.

     On March 30, 2005, the Company received an extension until May 15, 2005
under Section 6.3(b) of our Loan and Security agreement, which required the
Company to deliver its annual audited financial statements to the Lender Group
within 90 days of our fiscal year, that ended on December 31, 2004.

     On April 1, 2005, the Company borrowed $6.0 million under the Company's
Loan and Security Agreement. The proceeds were used to pay the interest due on
April 1 under the Company's 11 7/8% senior secured notes.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
         FINANCIAL DISCLOSURE

     Not applicable.

ITEM 9A.  CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

     We maintain disclosure and controls and procedures (as defined in Exchange
Act Rules 13a -- 15(e) and 15d -- 15(e)) that are designed to ensure that
information required to be disclosed in reports that we file or submit under the
Securities Exchange Act of 1934 is recorded, processed, summarized, and reported
within the time periods specified in the Securities and Exchange Commission's
rules and forms, and that such information is accumulated and communicated to
our management, including our Chief Executive Officer and Chief Financial
Officer, as appropriate, to allow timely decisions regarding the required
disclosure.

     As of December 31, 2004, an evaluation was performed under the supervision
and with the participation of the Company's management, including the CEO and
CFO, of the effectiveness of the design and operation of the Company's
disclosure controls and procedures. As further discussed below, based on that
evaluation, the Company's management, including the CEO and CFO, concluded that
the Company's disclosure controls and procedures were not effective as of
December 31, 2004.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

     Other than the material weakness discussed below, during the Company's
fourth fiscal quarter, there were no changes in internal control over financial
reporting (as defined in Exchange Act Rules 13a -- 15(f) and

                                       128

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

15(d) -- 15(f)) that have materially affected or are reasonably likely to
materially affect the Company's internal control over financial reporting.

     Following a comprehensive review of the Company's deferred tax assets and
deferred tax liabilities, we determined that certain deferred tax liabilities
had been incorrectly offset against its deferred tax assets. Under Statement of
Financial Accounting Standard 109, "Accounting for Income Taxes" ("SFAS 109")
taxable temporary differences related to indefinite-lived intangible assets or
tax-deductible goodwill (for which reversal cannot be anticipated) should not
have been offset by the Company against deductible temporary differences for
other indefinite-lived intangible assets or tax-deductible goodwill when
scheduling reversals of temporary differences.

     The Company evaluated the materiality of the correction on its consolidated
financial statements using the guidelines of Staff Accounting Bulletin No. 99,
"Materiality" and concluded that the cumulative effects of the corrections were
material to its annual consolidated financial statements for 2004, 2003 and 2002
and the related quarterly consolidated financial statements for such periods. As
a result, the Company concluded that it will restate its previously issued
consolidated financial statements to recognize the impact of the correction. See
Note 2 -- Restatement, in the notes to the consolidated financial statements
included under Item 8 within this Annual Report on Form 10-K.

     A material weakness is a condition in which the design or operation of one
or more of the internal control components does not reduce to a relatively low
level the risk that misstatements caused by error or fraud in amounts that would
be material in relation to the financial statements being audited may occur and
not be detected within a timely period by employees in the normal course of
performing their assigned functions. The Company concluded that the matter
discussed above represents a material weakness in our disclosure controls and
procedures and internal control over financial reporting.

     We have taken steps to remediate this material weakness by adding
additional levels of tax review and requiring all personnel who have
responsibilities for the Company's income taxes to attend an annual SFAS 109
review course.

  AGREEMENTS REGARDING BOARD REPRESENTATION

     The holders of the preferred stock were initially entitled to appoint three
members to our Board of Directors. Pursuant to the agreement by which Penton
sold its preferred stock and related warrants to a group of investors led by
ABRY Mezzanine Partners, L.P., Mr. Daniel Budde (formerly of ABRY Partners, LLC)
and Mmes. Craven and Garber were appointed by the Board of Directors of Penton
to serve as directors of Penton. At the 2003 annual meeting of stockholders, Mr.
Budde and Mmes. Craven and Garber were elected to the Board of Directors by the
preferred stockholders to serve a three-year term expiring in 2007. Mr. Budde
resigned from the Board on June 11, 2004 and was replaced by Mr. Royce Yudkoff
of ABRY Partners, LLC.

     At such time as the holders of convertible preferred stock cease to hold
shares of preferred stock having an aggregate liquidation preference of at least
$25 million, they will lose the right to appoint the director for one of these
three Board seats.

     Upon the occurrence of the following events, the holders of a majority of
the preferred stock may nominate two additional members to our Board of
Directors and, if such triggering events have not been cured or waived prior to
the end of the next succeeding quarter, may appoint one less than a minimum
majority of our Board of Directors:

        - failure to comply with certain specified covenants and obligations
          contained in the convertible preferred stock certificate of
          designations or purchase agreement and such failure is not cured
          within 90 days;

        - any representation or warranty in the convertible preferred stock
          purchase agreement is proven to be false or incorrect in any material
          respect; and

        - any default that results in the acceleration of indebtedness, where
          the principal amount of such indebtedness, when added to the principal
          amount of all other indebtedness then in default, exceeds $5 million
          or final judgments for the payment of money aggregating more than $1
          million (net of insurance proceeds) are entered against the Company
          and are not discharged, dismissed, or stayed pending appeal within 90
          days after entry.

     As of April 1, 2003, the holders of preferred stock were entitled to two
additional seats on the Board of Directors as a result of Penton's leverage
ratio, as determined in accordance with the terms of the preferred stock
purchase agreement, exceeding 7.5 to 1.0. In accordance with agreements entered
into at the time of the private placement, Messrs. John Meehan and David
Nussbaum resigned as directors. The Board of Directors appointed Messrs. Kelly
and Sook to fill the vacancies and serve until the annual meeting.

     Upon the occurrence of the following events, the holders of a majority of
the preferred stock may appoint one less than a minimum majority of our Board of
Directors:

        - failure to pay the liquidation preference or any cash dividends, to
          the extent declared, when due; and

        - failure to comply with certain specified covenants and obligations
          contained in the preferred stock certificate of designations or
          purchase agreement.

     Upon the occurrence of the following event, the holders of a majority of
the preferred stock may appoint a minimum majority of our Board of Directors:

        - Penton initiates or consents to proceedings under any applicable
          bankruptcy, insolvency, composition, or other similar laws or make a
          conveyance or assignment for the benefit of our creditors generally,
          or any holders of any lien takes possession of, or a receiver,
          administrator, or other similar officer is appointed for all or
          substantially all of our properties, assets or revenues and is not
          discharged within 90 days.

     On March 19, 2008, the holders of a majority of the preferred stock then
outstanding, if they meet the threshold described in the following paragraph,
will be entitled to appoint one less than a minimum majority of

                                       132
<PAGE>

our Board of Directors, subject to the right to appoint a minimum majority of
our Board of Directors as described in the immediately preceding paragraph.

     At such time as the holders of preferred stock cease to hold shares of
convertible preferred stock having an aggregate liquidation preference of at
least $10 million and such holders' beneficial ownership of our preferred stock
and common stock constitutes less than 5% of the aggregate voting power of our
voting securities, the holders of preferred stock will no longer have the right
to have any member on our Board of Directors.

     The Company has also granted the holders of the preferred stock the right
to have representatives attend meetings of the Board of Directors until such
time as they no longer own any preferred stock, warrants or shares of common
stock issued upon conversion of the preferred stock and exercise of the
warrants.

(1) The assumed annual rates of appreciation in the price of common stock are in
    accordance with rules of the Securities and Exchange Commission and are not
    predictions of future market prices of the common stock nor of the actual
    values the named executive officers will realize. In order for such annual
    rates of appreciation to be realized over the 10-year term of the options,
    the market price of the common stock would have to increase to $1.47/share
    (5%) or $2.33/share (10%) during that term. In such event, and assuming
    corresponding annual rates of increase for the market price of common stock,
    the market value of all currently outstanding shares of common stock would
    have increased by approximately $50,697,172 (5%) or $80,356,742 (10%) during
    that 10-year term.

(2) Consists of non-qualified options to purchase common stock granted under the
    Equity Incentive Plan at an exercise price equal to the closing price of the
    common stock on the date of grant, February 3, 2004. Each option becomes
    fully exercisable on the third anniversary of the date of grant, subject to
    full or partial acceleration in the event of earlier termination of
    employment (full acceleration if earlier termination is on account of death,
    permanent disability, retirement upon or after reaching age 65 or upon a
    change of control of Penton; partial acceleration in increments of 33 1/3%
    each year commencing one year after the date of grant if termination is for
    any other reason other than for "cause").

BOARD COMPENSATION

     Compensation of non-employee directors consists of an annual retainer of
$20,000, plus $3,000 for each Board meeting attended in person, $1,000 for each
Board meeting attended by telephone and $1,000 for each Board committee meeting
attended, except that only $500 is paid for attending a committee meeting held
on the same day as a Board meeting. The Chairman of the Audit Review Committee
is paid an additional $5,000 per year. Ms. Craven, Ms. Garber and Mr. Yudkoff
and employee directors are not compensated by the Company for serving as
directors.

     Each director of Penton will be reimbursed by Penton for out-of-pocket
expenses incurred in attending Board and Board committee meetings.

     Penton has adopted the Penton Media, Inc. 1998 Director Stock Option Plan
(as Amended and Restated Effective as of March 15, 2001) for non-employee
directors. The plan was approved by the stockholders at the 1999 annual meeting,
and an increase in the number of shares of common stock authorized under the
plan was approved by stockholders at the 2001 annual meeting. Pursuant to the
plan, and subject to certain limitations contained in it, the Board may grant
non-qualified options to purchase common stock, at an exercise price not less
than fair market value on the date of grant, to directors of Penton who at the
time of grant are not employees of Penton or any of its subsidiaries. In
addition, the Board may authorize the grant of restricted stock or deferred
shares to non-employee directors under the plan. The plan also provides that the
Board may permit non-employee directors to elect to receive non-qualified
options, restricted stock or deferred shares in lieu of all or a portion of such
non-employee director's compensation otherwise payable in cash.

EMPLOYMENT AGREEMENT WITH MR. KEMP

     During his service as Chief Executive Officer of Penton from January 1,
2004 through June 30, 2004, Mr. Kemp had an employment agreement with Penton.

     Mr. Kemp's agreement provided for participation in Penton's Supplemental
Executive Retirement Plan. Effective December 31, 2003, the Supplemental
Executive Retirement Plan was frozen and all participants ceased to accrue
benefits under the plan on such date. The agreement also provided for
supplementary life insurance in an amount equal to one and one-half times Mr.
Kemp's salary and supplementary long-term disability coverage that provided for
a maximum monthly benefit (when combined with Penton's base long-term disability
plan) of $18,333 per month.

     In addition, the agreement provided for additional supplementary life and
long-term disability insurance coverage that would provide benefits, in the
event of Mr. Kemp's covered death or disability, in the amount of $4,000,000,
payable in a single lump sum.

                                       136
<PAGE>

     The employment agreement for Mr. Kemp provided for a payment to him in an
amount equal to the total of all income taxes imposed on him as a result of (a)
the provision of the life insurance and the long-term disability coverage, (b)
imputed income to him with respect to the Senior Executive Loan Program and (c)
such payment. The employment agreement for Mr. Kemp also provided for a payment
to him in an amount equal to the total of all income taxes imposed on him as a
result of (a)(i) the issuance to him of the deferred shares granted to him on
April 23, 2002, on an accelerated basis following a change of control, his death
or permanent disability, a termination without cause, a termination by him for
good reason or involuntary retirement or (ii) any other issuance of the deferred
shares if a change of control occurred prior to the payment in full of amounts
due under the Senior Executive Loan Program and (b) such payment.

     The employment agreement for Mr. Kemp further entitled him to receive a
payment in the event that the excise tax under Section 4999 of the Internal
Revenue Code applied to the issuance of the deferred shares or the payment
described in the preceding paragraph and the sum of (a) the value of the
deferred shares (reduced by such excise tax) plus (b) the value of the shares
purchased by him pursuant to the Senior Executive Loan Program plus (c) the
proceeds of any life insurance or long-term disability coverage ((a), (b) and
(c), the "Loan Payments") was less than the amount due and owing under the
Senior Executive Loan Program at the time of the change of control (the "Change
of Control Loan Balance"). In that event, the payment referred to in the
preceding sentence would have been in an amount equal to the sum of (x) the
lesser of (1) the difference between the Change of Control Loan Balance and the
Loan Payments or (2) 20% of the sum of the value of the deferred shares at the
time of the change of control plus such payment plus (y) an amount, such that
after payment of all taxes (including any excise tax under Code Section 4999)
imposed on such payment, Mr. Kemp retained an amount equal to the Code Section
4999 excise tax imposed upon such payment.

     The agreement also provided that in the event that Mr. Kemp's employment
was terminated by Penton (other than for "cause" (as defined in the agreement)
or by reason of his death, disability or retirement) or by him for "good reason"
(as defined in the agreement), Mr. Kemp would have been entitled to receive
certain severance benefits.

     Upon the occurrence of the events described in the preceding paragraph, Mr.
Kemp would have been entitled to receive (a) any accrued but unpaid salary and
expense reimbursement and (b) his salary (as in effect at the time of
termination or, if higher, as in effect as of the most recent extension of the
employment period) for a period of three years following the date of his
termination of employment. In addition, in the event that the employment of Mr.
Kemp was terminated by Penton other than for cause or by Mr. Kemp for good
reason within the two-year period following a "change of control," he would have
been entitled to receive a payment (payable, at his option, in a lump sum) equal
to (i) Mr. Kemp's target bonus for the year in which the termination occurred
or, if higher, his target bonus for the preceding year or the year in which the
change of control occurred and (ii) if his employment was terminated after July
1 of the then-current year, a pro-rated portion of his target bonus for the year
in which the termination occurred or, if higher, a pro-rated portion of his
target bonus for the preceding year or the year in which the change of control
occurred. Mr. Kemp would also have been entitled to the continuation of certain
additional benefits (e.g., medical insurance).

     Payments and benefits under the employment agreement were subject to
reduction in order to avoid the application of the excise tax on "excess
parachute payments" under the Internal Revenue Code, but only if the reduction
would increase the net after-tax amount received by him.

     The agreement included non-competition, non-solicitation and
confidentiality obligations on the part of Mr. Kemp, which survived its
termination.

SEPARATION AGREEMENT WITH MR. KEMP

     On March 24, 2004, the Company announced that Mr. Kemp would be leaving the
Company. Mr. Kemp's employment was terminated effective June 30, 2004, and on
July 1, 2004, Mr. Kemp and the Company signed a Separation Agreement and General
Release agreement. Mr. Kemp's separation agreement

                                       137
<PAGE>

provides for the following: (1) a lump-sum payment of approximately $2.3
million, of which $0.8 million has been placed in escrow, (included in this
payment is severance of approximately $1.8 million per Mr. Kemp's employment
agreement; $0.3 million related to performance units granted on May 22, 2003;
and $0.2 million related to the settlement of Mr. Kemp's accrued supplemental
executive retirement plan obligation); (2) the accelerated vesting of 100,000
stock options granted to Mr. Kemp prior to his termination making them
immediately exercisable; (3) the immediate vesting of 125,000 performance shares
in accordance with the terms of his performance share agreement dated February
5, 2002; (4) the immediate vesting of restricted stock units granted to Mr. Kemp
under Penton's Management Stock Purchase Plan; (5) continued participation for
Mr. Kemp and his eligible dependents in Penton's group health plan for 18 months
after his termination; (6) Penton will use its reasonable best efforts to
maintain term life insurance and long-term disability coverage for Mr. Kemp's
benefit until the date that he has no outstanding balance under the Executive
Loan Program in an amount equal to at least the total amount Mr. Kemp would be
required to remit under applicable tax laws if an amount equal to the remaining
outstanding balance due under the note were paid to Mr. Kemp and the payment was
treated as compensation paid to an employee; and (7) each year, Penton will make
a payment to Mr. Kemp in an amount equal to the total of all income taxes
imposed on Mr. Kemp as a result of (a) the provision of the life insurance and
long-term disability coverage and (b) such payment.

     In addition, the Board and Mr. Kemp agreed upon a number of provisions
related to Mr. Kemp's outstanding executive loan balance. The underlying goal of
these provisions was to mitigate any tax exposure to the Company should the loan
be discharged at a future date. Specifically, $0.8 million of the lump-sum
payment described above has been placed in escrow and will be returned to Mr.
Kemp only if he pays off the entire loan balance by its due date. Furthermore,
Mr. Kemp has granted Penton a security interest in approximately 1.1 million
shares of Penton common stock. These pledged securities could be transferred to
Penton's ownership under certain circumstances and used to pay down the
outstanding loan balance.

     On June 28, 2004, Mr. Kemp was granted 514,706 deferred shares that vested
on January 3, 2005. In return for these shares, Mr. Kemp agreed to comply with
the terms of certain restrictive covenants, including a non-compete and a
non-solicitation covenant.

EMPLOYMENT AGREEMENTS WITH MESSRS. NUSSBAUM, VICE AND DENNY

     The Compensation Committee approved initial employment agreements with each
of Messrs. Nussbaum, Vice and Denny in 1998, 1999 and 2000, respectively. Each
of these employment agreements was amended on December 11, 2001, and Mr.
Nussbaum's employment agreement was further amended on June 23, 2004. The
agreements are for terms currently expiring June 23, 2006, in the case of Mr.
Nussbaum; August 24, 2006, in the case of Mr. Vice; and October 15, 2006, in the
case of Mr. Denny; and renew automatically for an additional year on each
anniversary of the effective date of the agreement (or until age 65, if earlier)
unless either party thereto elects otherwise, but may be terminated by the
executive with 120 days notice.

     The agreements for Messrs. Vice and Denny provide for participation in
Penton's Supplemental Executive Retirement Plan. Effective December 31, 2003,
the Supplemental Executive Retirement Plan was frozen and all participants
ceased to accrue benefits under the plan on such date. The agreements also
provide for supplementary life insurance in an amount equal to one and one-half
times each executive's salary in the case of Mr. Denny and one times the
executive's salary in the case of Messrs. Nussbaum and Vice and supplementary
long-term disability coverage that provides for a maximum monthly benefit (when
combined with Penton's base long-term disability plan) of $18,333 per month for
Messrs. Nussbaum and Denny and $10,000 per month in the case of Mr. Vice.

     In addition, the agreements provide for additional supplementary life and
long-term disability insurance coverage for Messrs. Vice and Denny that would
provide benefits, in the event of the executive's covered death or disability,
in the amount of $900,000 for Mr. Vice; and $270,000 for Mr. Denny, each payable
in a single lump sum. In the event the life or long-term disability insurance
coverage described in the preceding sentence cannot be procured or maintained,
Penton will pay the benefit from its own funds.

                                       138
<PAGE>

     The employment agreements for Messrs. Vice and Denny provide for a payment
to each executive in an amount equal to the total of all income taxes imposed on
the executive as a result of (a) the provision of the life insurance and the
long-term disability coverage, (b) imputed income to the executive with respect
to the Senior Executive Loan Program and (c) such payment.

     The employment agreements for Messrs. Vice and Denny also provide for a
payment to each executive in an amount equal to the total of all income taxes
imposed on the executive as a result of (a)(i) the issuance to the executive of
the deferred shares granted to the executive on April 23, 2002, on an
accelerated basis following a change of control, the executive's death or
permanent disability, a termination without cause, a termination by the
executive for "good reason" (as defined in the agreements and as described
below) or involuntary retirement or (ii) any other issuance of the deferred
shares if a change of control occurs prior to the payment in full of amounts due
under the Senior Executive Loan Program and (b) such payment.

     The employment agreements for Messrs. Vice and Denny further entitle the
executive to receive a payment in the event that the excise tax under Section
4999 of the Internal Revenue Code applies to the issuance of the deferred shares
or the payment described in the preceding paragraph and the sum of (a) the value
of the deferred shares (reduced by such excise tax) plus (b) the value of the
shares purchased by the executive pursuant to the Senior Executive Loan Program
plus (c) the proceeds of any life insurance or long-term disability coverage
((a), (b) and (c), the "Loan Payments") is less than the amount due and owing
under the Senior Executive Loan Program at the time of the change of control
(the "Change of Control Loan Balance"). In that event, the payment referred to
in the preceding sentence will be in an amount equal to the sum of (x) the
lesser of (1) the difference between the Change of Control Loan Balance and the
Loan Payments or (2) 20% of the sum of the value of the deferred shares at the
time of the change of control plus such payment, plus (y) an amount, such that
after payment of all taxes (including any excise tax under Code Section 4999)
imposed on such payment, the executives retain an amount equal to the Code
Section 4999 excise tax imposed upon such payment.

     The agreements also provide that in the event the executive's employment is
terminated by Penton (other than for "cause" (as defined in the agreements) or
by reason of his death, disability or retirement) or by the executive for good
reason, the executive will be entitled to receive certain severance benefits.

     In the case of Mr. Nussbaum, he is entitled to receive (a) any accrued but
unpaid salary and expense reimbursement; (b) his salary (as in effect at the
time of termination or, if higher, as in effect as of the most recent extension
of the employment period) for a period of 12 months after termination of
employment; and (c) a lump sum payment equal to his target bonus.

     In the case of Messrs. Vice and Denny, each such executive is entitled to
receive (a) any accrued but unpaid salary and expense reimbursement and (b) his
salary (as in effect at the time of termination or, if higher, as in effect as
of the most recent extension of the employment period) for a period of two years
following the date of his termination of employment. In addition, in the event
that the employment of Messrs. Vice or Denny is terminated by Penton other than
for cause or by the executive for good reason within the two-year period
following a "change of control," each such executive will be entitled to receive
a payment (payable, at the executive's option, in a lump sum) equal to his
target bonus for the year in which the termination occurs or, if higher, the
executive's target bonus for the preceding year or the year in which the change
of control occurs. All executives party to such agreements are also entitled to
the continuation of certain additional benefits (e.g., medical insurance).

     Payments and benefits under the employment agreements are subject to
reduction in order to avoid the application of the excise tax on "excess
parachute payments" under the Internal Revenue Code, but only if the reduction
would increase the net after-tax amount received by the executive.

     The transactions that are deemed to result in a change of control for the
purposes of these agreements include: (a) any person (with certain exceptions as
described in the agreements) becoming the beneficial owner of 40% or more of the
voting stock of Penton; (b) individuals who, as of the date of the agreements,
constitute the Board of Directors (the "Incumbent Board") cease for any reason
(other than death or disability) to constitute at least a majority of the Board
of Directors (provided that any individual who

                                       139
<PAGE>

becomes a director subsequent to the date of the agreements whose appointment or
election is approved by a majority of the Incumbent Board is considered to be a
member of the Incumbent Board); (c) a merger or consolidation with, or sale of
all of or substantially all of Penton's assets to another entity, as a result of
which less than a majority of the voting shares of the surviving entity are
owned by former stockholders of Penton; and (d) approval by the stockholders of
Penton of a complete liquidation or dissolution of Penton. "Good reason" for
termination of employment by the executive includes reduction in salary, the
failure by Penton to extend the executive's employment under the agreement or a
breach by Penton of the terms of the agreement and, in the case of Mr. Nussbaum,
a change of control.

     Each agreement includes non-competition, non-solicitation and
confidentiality obligations on the part of the executive, which survive its
termination.

PLANS AND ARRANGEMENTS

Retirement Plan

     Participants in the Penton Media, Inc. Retirement Plan consist of a
majority of the full-time employees of Penton and its subsidiaries in the United
States, including the executive officers. The plan is fully paid for by Penton,
and employees become fully vested after five years of service. The annual
benefit payable to an employee under the plan upon retirement, computed as a
straight life annuity amount, equals the sum of the separate amounts the
employee accrues for each of his years of service under the plan. Such separate
amounts are determined as follows: for each year through 1988, 1.2% of such
year's compensation up to the Social Security wage base for such year and 1.85%
(2.0% for years after 1986) of such year's compensation above such wage base;
for each year after 1988 through the year in which the employee reaches 35 years
of service, 1.2% of such year's "covered compensation" and 1.85% of such year's
compensation above such "covered compensation;" and for each year thereafter,
1.2% of such year's compensation. Years of service and compensation with Pittway
Corporation prior to Penton's spinoff from Pittway in August of 1998 are taken
into account under the plan. The employee's compensation under the plan for any
year includes all salary (before any election under Pittway's or Penton's salary
reduction plan or cafeteria plan), commissions and overtime pay and, beginning
in 1989, bonuses, subject to such year's limit applicable to tax-qualified
retirement plans ($160,000 for 1999, $170,000 for 2000 and 2001, and $200,000
each year thereafter). The employee's "covered compensation" under the plan for
any year is generally the average, computed as of such year, of the Social
Security wage bases for each of the 35 years preceding the employee's Social
Security retirement age, assuming that such year's Social Security wage base
will not change in the future. Normal retirement age under the plan is age 65,
and reduced benefits are available as early as age 55. Benefits are not subject
to reduction for Social Security benefits or other offset amounts.

     Effective December 31, 2003, the plan was frozen and participants in the
plan ceased to accrue benefits under the plan as of such date. Estimated annual
benefits payable under the plan upon retirement at normal retirement age for the
following persons (assuming 1999 compensation at $160,000, 2000 and 2001
compensation at $170,000 and 2002 and 2003 compensation at $200,000) are $19,621
for Mr. Kemp; $14,229 for Mr. Nussbaum; $6,369 for Mr. Denny and $52,342 for Mr.
Vice.

Supplemental Executive Retirement Plan

     Messrs. Kemp, Denny, Nussbaum and Vice participate in Penton's Supplemental
Executive Retirement Plan, which is not tax-qualified. The annual benefit
payable to a participant under the plan at age 65, computed as a straight life
annuity amount, equals the sum of the separate amounts the participant accrues
for each of his years of service after September 3, 1996, for Mr. Kemp;
September 8, 1998, for Mr. Nussbaum; October 16, 2000, for Mr. Denny; and
February 15, 1974, for Mr. Vice. Years of service and compensation with Pittway
are taken into account. The separate amount for each such year is 1.85% of that
portion of the participant's salary and annual discretionary cash bonus, if any,
for such year (before any election under Pittway's or Penton's salary reduction
plan, and including any portion of such bonus taken in the form of Deferred
Shares Awards) in excess of the limit applicable that year to the compensation
that may be taken into account under tax-qualified retirement plans ($160,000 in
1999, $170,000 in 2000 and 2001 and $200,000

                                       140
<PAGE>

in 2002 and 2003) but less than $500,000. Benefits are not subject to reduction
for Social Security benefits or other offset amounts. Accrued benefits are
subject to forfeiture in certain events. Effective December 31, 2003, the plan
was frozen and participants in the plan ceased to accrue benefits under the plan
as of such date. Estimated annual benefits payable under the plan upon
retirement at age 65 for the following persons are $27,300 for Mr. Nussbaum;
$10,564 for Mr. Denny and $11,421 for Mr. Vice.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     None of the individuals who served as members of the Compensation Committee
of the Board of Directors in 2004 was or has been an officer or employee of
Penton or engaged in transactions with Penton (other than in his capacity as
director).

  *  Less than one percent

 (1) Except as otherwise indicated below, beneficial ownership means the sole
     power to vote and dispose of shares.

 (2) Calculated using 34,487,872 the number of shares of common stock
     outstanding as of March 31, 2005. This number excludes the number of shares
     of common stock (a) into which the outstanding Series C preferred stock is
     convertible, (b) for which the outstanding warrants are exercisable and (c)
     for which any options to purchase common stock held by directors and
     executive officers are exercisable.

 (3) The information as to ABRY Mezzanine Partners, L.P. ("ABRY") and entities
     controlled directly or indirectly by ABRY is derived in part from Schedule
     13D, as filed with the Securities and Exchange Commission on March 28,
     2002, statements required to be filed by ABRY pursuant to Section 16(a) of
     the Exchange Act, and information furnished to Penton separately by ABRY.

 (4) ABRY does not currently own any shares of common stock. This number
     represents the number of shares of common stock ABRY would be entitled to
     receive upon conversion of its preferred stock and exercise of its warrants
     to purchase common stock. ABRY and its affiliated entities currently own
     30,000 shares of preferred stock convertible, as of March 31, 2005, into
     approximately 4,963,845 shares of common stock and warrants to purchase an
     aggregate of 960,000 shares of common stock.

 (5) This number reflects the total number of shares of common stock such holder
     is entitled to receive upon conversion of its preferred stock and exercise
     of the related warrants. The number of shares into which a share of
     preferred stock is convertible is calculated by dividing its current
     liquidation preference by the conversion price of $7.61. The liquidation
     preference is the sum of the liquidation value of the preferred stock,
     currently $1,000, plus any accrued dividends. Currently, dividends compound
     and accrue daily. Consequently, the number of shares into which the
     preferred stock is convertible increases daily. So long as any of Penton's
     10 3/8% senior subordinated notes due 2011 and 11 7/8% senior secured notes
     due 2007 remain outstanding, the number of shares of common stock that each
     of ABRY and its affiliated entities, ABACUS Fund Partners, LP, ABACUS Fund,
     Ltd. and Sandler Capital Management and its affiliated entities are
     entitled to receive pursuant to the conversion of their preferred stock and
     exercise of the warrants is limited by the terms of the Certificate of
     Designations governing the preferred stock and warrant agreements,
     respectively, to prevent any holder or group of holders of preferred stock
     or warrants from becoming the beneficial owner of more than 35% of the
     aggregate votes of the outstanding capital stock of Penton entitled to vote
     in the election of directors. Currently, no holder of preferred stock is
     limited by this provision.

 (6) ABACUS Fund Partners, LP and ABACUS Fund, Ltd. do not currently own any
     shares of common stock. This number represents the number of shares of
     common stock they would be entitled to receive upon conversion of their
     preferred stock and exercise of their warrants to purchase common stock.
     They currently own 5,000 shares of preferred stock convertible, as of March
     31, 2005, into approximately 826,343 shares of common stock and warrants to
     purchase an aggregate of 160,000 shares of common stock.

 (7) The information as to Mario J. Gabelli and entities controlled directly or
     indirectly by Mr. Gabelli is derived from Schedule 13D/A, as filed with the
     Securities and Exchange Commission on January 27, 2005, and statements
     required to be filed by Mr. Gabelli and entities controlled directly or
     indirectly by

     regulations thereunder, and (c) with respect to Penton common stock, Mr.
     Gabelli and such entities have the sole power to vote and dispose of all
     the shares of which they are beneficial owners, unless the aggregate voting
     interest of all such entities exceeds 25% of Penton's total voting interest
     or other special circumstances exist, in which case the proxy voting
     committees of certain of such entities would have the sole power to vote
     certain shares of Penton common stock except 93,383 shares of Penton's
     common stock as to which they have no voting power.

 (8) The information as to Mr. Greene is derived in part from Schedule 13D, as
     filed with the Securities and Exchange Commission on June 21, 1999,

     2005, into approximately 2,481,510 shares of common stock and warrants to
     purchase an aggregate of 480,000 shares of common stock.

(12) Ms. Craven may be deemed to beneficially own the stock beneficially owned
     by Sandler and its affiliated entities because of her relationship with
     Sandler and its affiliated entities and because she was appointed to
