NOTE 1 -- BASIS OF PRESENTATION

         The consolidated financial statements include the accounts of Penton
Media, Inc. (formerly known as Penton Publishing, Inc.) and its subsidiaries
("Penton" or the "Company"). The Company was a wholly owned subsidiary of
Pittway Corporation ("Pittway" or "Parent Company") until August 7, 1998, when
it was spun off as a separate entity (See Note 2).

         The accompanying unaudited interim consolidated financial statements
have been prepared pursuant to the rules and regulations of the Securities and
Exchange Commission. Accordingly, certain information and footnote disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been omitted.

         In the opinion of management, the interim consolidated financial
statements reflect all adjustments necessary for a fair presentation of the
interim periods. The results of operations for the interim periods are not
necessarily indicative of the results of operations to be expected for the full
year.


NOTE 2 - SPIN-OFF FROM PITTWAY AND SUBSEQUENT ACQUISITION

         On August 7, 1998 Pittway distributed 100% of the Company's Common
Stock on a share-for-share basis to holders of Pittway stock. Immediately
thereafter, the Company completed the acquisition of Donohue Meehan Publishing
Company.

         Donohue Meehan Publishing Company ("DM Publishing") was acquired for $7
million in cash, 6.76% (1,541,638 shares) of the Company's stock to be
outstanding immediately after the acquisition, and up to an additional $4
million in cash based on DM Publishing's pre-tax income for the years 1998 and
1999. The Company also agreed to make a contingent cash payment to the extent,
if any, that the shares issued in the acquisition have an average aggregate
market value less than $29 million during either of two 30-day periods in the
year 2000. The contingent payment is subject to certain limitations as to any of
such shares sold prior to the



                                       7

payment. A portion of the contingent payment may be made with Common Stock
rather than cash under certain conditions.


NOTE 3 - PRO FORMA FINANCIAL INFORMATION

         The following unaudited supplemental pro forma operating data is
presented for the nine months ended September 30, 1998 as if the DM Publishing

NOTE 4 - RELATIONSHIP AND TRANSACTIONS WITH PITTWAY

         Included in the consolidated statement of income is an allocation of
corporate expenses related to services provided to the Company by Pittway.
Certain of the Company's employees participated in Pittway's 1990 Stock Awards
Plan, for which Pittway has allocated costs to the Company totaling $1,412 and
$443 in the nine months ended September 30, 1998 and 1997, respectively. The
allocated costs from Pittway to the Company total $1,291 and $361 for the third
quarters ended September 30, 1998 and 1997, respectively.



                                       8

<PAGE>   9



         In August 1998, the Company and Pittway agreed to discharge the 
majority of the amount due from the parent company by a charge to stockholders'
equity in the amount of approximately $17.0 million.


NOTE 5 - INVENTORIES

         The LIFO reserve balances of $585 and $462 at September 30, 1998 and
December 31, 1997, respectively, represent the excess of current replacement
cost over the LIFO value of inventory, which consists principally of raw
materials.


NOTE 6 - NOTES PAYABLE AND REVOLVING CREDIT FACILITY

         The Company's short-term note payable at September 30, 1998 represents
foreign indebtedness, is denominated in British pounds and bears interest at
8.1%. The note, due in December 1998, is convertible into Common Stock at fair
market value.

         Concurrent with the spin-off from Pittway, the short-term notes payable
of $27,800 of foreign debt, including accrued interest, denominated in British
pounds and bearing interest at 8.1% and the $5,000 domestic note bearing
interest at 6% were refinanced with a new revolving credit facility. The new
facility, which provides for the availability of up to $75 million, bears
interest at LIBOR plus a margin of between 0.5% and 0.875% (currently at 6.125%
domestic and 8.1% foreign), and includes a commitment fee for the unused portion
of the facility of between 0.125% and 0.250%.


NOTE 7 - NET INCOME PER SHARE

         Net income per share reflects net income divided by the average number
of shares outstanding, including the shares issued in the acquisition of Donohue
Meehan Publishing Company in August 1998.


NOTE 8 - SUBSEQUENT EVENT

         On October 8, 1998, the Company signed a definitive merger agreement to
acquire Mecklermedia Corporation ("Meckler"). On October 15, 1998, the Company
commenced a tender offer to acquire all outstanding shares of Meckler



                                       9

for $29 per share. It is anticipated that the tender offer will be completed in
late November 1998.


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

         The following discussion should be read in conjunction with the
accompanying unaudited consolidated financial statements and the notes thereto.

Impact of Acquisition

         As noted above, the Company was spun off from Pittway and acquired DM
Publishing in August 1998. As the Company acquires additional companies, its
sales mix, market focus, cost structure, operating leverage and the seasonality
of the business may change significantly. Consequently, the Company's historical
and future results of operations reflect and will reflect the impact of
acquisitions, and period-to-period comparisons may not be meaningful in certain
respects. Historical information for companies subsequent to their acquisition
may include integration and other costs that are not expected to continue in the
future.

RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED WITH THE NINE MONTHS ENDED
SEPTEMBER 30, 1997

Revenues

         Total revenues, after elimination of inter-segment sales, increased
$11.1 million, or 7%, from $153.4 million to $164.5 million.

         Media services revenues increased $9.4 million, or 7%, to $145.6
million. Advertising revenues from Penton's publishing operations accounted for
$5.4 million of the increase, primarily due to the following; (1) the
publication of Hydraulics and Pneumatics' Fluid Power Handbook and Directory,
which is published every other year, (2) two new publications launched in the
first quarter, IW Growing Companies and Penton's Embedded Systems Development,
(3) the Donohue Meehan acquisition in August 1998, and (4) higher pricing on
other advertising business. The remaining $4.0 million increase resulted from an
increase in trade show and conference revenues. The increase is due to the
first-time inclusion of the operations of Independent



                                       10

<PAGE>   11



Expositions, Ltd. ("INDEX") -- specifically, the Service Management Europe Show
in March -- and Industrial Shows of America ("ISOA") -- 10 regional shows in the
second quarter. Both INDEX and ISOA were acquired in December 1997. In addition,
1998 includes an increase in the Wireless Symposium & Exhibition/Portable by
Design Show. These increases were partially offset by lower exhibition revenues
for certain other shows.

         Printing revenues increased $1.5 million, or 5%, bringing total segment
revenue to $30.1 million. Sales to external customers increased $1.0 million or
12%, to $8.8 million.

         Direct-mail marketing revenues increased $0.6 million, or 6%, to $10.0
million. The increase was primarily in the segment's printing operations.

Cost of Production

         Total cost of production, after elimination of inter-segment charges,
grew to $74.8 million in 1998 compared with $71.3 million in 1997, representing
an increase of $3.5 million, or 5%.

         Media services production costs grew 3%, due to the inclusion of the
INDEX and ISOA trade shows acquired in late 1997, and also to the publication of
the biannual Fluid Power Handbook and Directory, which was not published in
1997.

         Cost of production for the Printing segment increased $1.5 million due
to volume-related growth of total business (including inside and outside).

         Direct-mail marketing cost of production decreased by 2%, compared with
the 6% increase in revenue, due largely to productivity improvements.

Selling, General, and Administrative

         Total selling, general, and administrative expenses grew $9.0 million,
or 16%, to $67.0 million.

         Media services selling, general, and administrative expenses increased
$9.0 million, or 17%. The increase was due to; (1) expenses of the INDEX and
ISOA trade shows held to date in 1998, (2) period costs of the remainder of the
newly acquired trade shows for which revenues will not be recognized until those
trade shows are held in future



                                       11

<PAGE>   12



periods, (3) costs related to launching two new publications in the first
quarter, IW Growing Companies and Penton's Embedded Systems Development, (4) the
Donohue Meehan acquisition (in August 1998), (5) one time spin off costs of
approximately $0.5 million, (6) costs related to the biannual Fluid Power
Handbook and Directory, (7) sales volume growth, and (7) higher charges related
to Pittway stock appreciation rights held by Penton employees. Total costs
charged to the Company by Pittway for the nine months ended September 30, 1998
and 1997 were $1.5 million and $1.0 million, respectively.

         Selling, general, and administrative expenses of the printing and the
direct-mail marketing segments were level with the prior year.

Depreciation and Amortization

         Depreciation and amortization increased $1.3 million to $6.3 million.
The higher expense was primarily the result of the amortization of intangible
assets associated with trade show company acquisitions completed in December
1997, and the Donohue Meehan acquisition in August 1998.

Operating Income

         Overall, the Company's operating income for the nine months decreased
$2.8 million, or 15%, to $16.3 million from $19.1 million in the prior year.

         Media services operating income decreased $2.9 million, or 15%. The
first three quarters of 1998 were negatively impacted by the period costs of the
trade shows acquired in 1997, start-up costs associated with the two magazine
launches, and higher amortization expense as noted above.

         Operating income of the printing segment decreased by $0.4 million to
$0.5 million.

         The Direct-mail marketing operations recorded an operating loss of $0.3
million compared with the prior year's operating loss of $0.8 million. The
improvement was largely due to the increase in revenue of this segment's
printing operations and lower production costs due to the elimination of certain
programs in 1998.



                                       12

<PAGE>   13


Interest Expense

         Interest expense increased $1.5 million, due to additional borrowings
used to finance the two trade show company acquisitions in December 1997, and
the Donohue Meehan acquisition in August 1998.

Effective Tax Rates

         The effective tax rates were 41.9% and 41.6%, for the first three
quarters of 1998 and 1997, respectively.


THREE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED WITH THE THREE MONTHS ENDED
SEPTEMBER 30, 1997

Revenues

         Total revenues, after elimination of inter-segment sales, increased
$2.1 million, or 4%, from $50.7 million to $52.8 million.

         Media services revenues increased $2.6 million, or 6%, to $46.3
million. Advertising revenues from Penton's publishing operations accounted for
$1.2 million of the increase, primarily due to advertising revenues from the
Donohue Meehan acquisition (in August 1998) and two new publications launched in
the first quarter, IW Growing Companies and Penton's Embedded Systems
Development. Trade show and conference revenues increased $1.4 million. The
increase is due largely to the first-time inclusion of the operations of ISOA
and INDEX (both acquired in December 1997).

         Printing revenues decreased $0.3 million, or 3%, bringing total segment
revenue to $10.1 million. Sales to external customers decreased $0.4 million or
13%, to $2.9 million, primarily due to the loss of a significant customer. These
revenues were partially off-set by the addition of one time catalog and
directory related business as well as several new customers.

         Direct-mail marketing revenues were level with prior year.




                                       13

<PAGE>   14

Cost of Production
       
         Total cost of production, after elimination of inter-segment charges,
grew to $24.6 million compared with $24.4 million, an increase of $0.2 million,
or 1%.

         Media services production costs grew approximately 1%, due largely to
the Donohue Meehan acquisition (in August 1998), the two new publications
launched in the first quarter, IW Growing Companies and Penton's Embedded
Systems Development, and the inclusion of the ISOA and INDEX trade shows
acquired in late 1997.

         Cost of production for the printing and direct mail marketing segments
were level with prior year.

Selling, General, and Administrative

         Total selling, general, and administrative expenses grew $2.3 million,
or 12%, to $21.3 million.

         Media services selling, general, and administrative expenses increased
$2.4 million, or 14%. The increase was due to; (1) expenses of the ISOA and
INDEX trade shows held to date in 1998, (2) period costs of other newly acquired
ISOA and INDEX trade shows for which revenues will not be recognized until those
trade shows are held in the fourth quarter, (3) the Donohue Meehan acquisition
(in August 1998), (4) one time spin off costs of approximately $0.5 million, and
(5) costs related to the two new publications launched in the first quarter, IW
Growing Companies and Penton's Embedded Systems Development. Total costs charged
to the company by Pittway for the third quarter were $0.1 million and $0.6
million for 1998 and 1997 respectively, primarily related (in both periods) to
Pittway stock appreciation rights held by Penton employees.

         Selling, general, and administrative expenses of the printing and the
direct-mail marketing segments were level with the prior year.

Depreciation and Amortization

         Depreciation and amortization increased $0.5 million to $2.2 million.
The higher expense was primarily the result of the amortization of intangible
assets associated with trade shows acquired in December 1997, and the Donohue
Meehan acquisition in August 1998.



                                       14

<PAGE>   15


Operating Income

         Overall, the Company's operating income for the three months decreased
$1.0 million, or 17%, to $4.7 million from $5.7 million in the prior year.

         Media services operating income decreased $0.6 million, or 11%. The
third quarter of 1998 was negatively impacted by the period costs of the trade
shows acquired in 1997, minor seasonal operating losses associated with the two
new magazine launches, and higher amortization expense as noted above.

         Operating income of the printing segment decreased $0.2 million to $0.1
million, due to lower revenues.

         Direct-mail marketing operated at break even, compared with prior
year's profit of $0.1 million.

Interest Expense

         Interest expense increased $0.6 million, due to additional borrowings
to finance the two trade show company acquisitions completed in December 1997,
and the Donohue Meehan acquisition in August 1998.

Effective Tax Rates

         The effective tax rates were 42.6% and 41.6%, for the third quarters of
1998 and 1997, respectively. The Company's acquisition of Donohue Meehan
resulted in the recording of goodwill. The amortization of such goodwill is
recognized for financial statement purposes but not deductible for tax purposes
due to the structure of the purchase transaction. Accordingly, the Company's
effective tax rate has increased. The Company's effective tax rate would have
been 41.3% for the third quarter of 1998, had such goodwill been deductible for
tax purposes.

EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION

         Earnings before interest expense, taxes, depreciation and amortization
("EBITDA") is a widely used and commonly reported standard measure utilized by
analysts and investors in the analysis of the media industry. EBITDA is not a
measure of performance under GAAP because it excludes those items listed above
which are significant components in understanding and evaluating the Company's
financial performance. However, the following EBITDA information can provide
additional information for determining the ability


                                       15

of the company to meet its debt service requirements and for other comparative
analyses of the Company's operating performance relative to other publishing 
companies. The Company's calculation of EBITDA is as follows (in thousands):

</TABLE>

         The Company's EBITDA decreased $1.5 million, or 6.0%, to $22.6 million
for the nine months ended September 30, 1998 from $24.1 million for the nine
months ended September 30, 1997. Increased period costs of the trade shows
acquired in 1997, start-up costs associated with the two magazine launches and
one time spin off costs were the primary contributing factors to the decrease in
EBITDA.

FOREIGN CURRENCY

         The functional currency of the Company's foreign operations acquired in
December 1997 is the local currency. Accordingly, assets and liabilities of
foreign operations are translated to 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 during 1997 or the nine months ended
September 30, 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Historically, cash flow generated by the Company's operations has been
used to invest in capital assets, finance acquisitions, and reduce debt. Excess
cash was used to pay dividends to Pittway Corporation, its former parent
company.

         For the first nine months of 1998, cash flow provided by operations was
$16.6 million, up $3.0 million from $13.6 million for the first nine months of
1997. The increase in 1998 was primarily due to an increase in unearned income
(primarily advance deposits related to fourth quarter trade shows) which was
partially off-set by a lower net income and 



                                       16

<PAGE>   17



increases in accounts receivable and prepayments and deposits.

         Cash from operating activities was used for capital expenditures ($4.3
million and $3.3 million in the first three quarters of 1998 and 1997,
respectively) and to make cash distributions to Pittway, including final
settlement of intercompany balances existing at the spin-off date.

         On August 7, 1998, the Company entered into a five-year, $75.0 million
unsecured revolving credit agreement, which includes an option to increase the
facility to $100 million. The Company's short-term notes payable were refinanced
with this facility, which was also utilized to finance the cash portion of the
acquisition price of Donohue Meehan Publishing Company. At September 30, 1998,
$38.5 million was outstanding under the revolving credit facility.

         Penton's management anticipates that Penton's long-term financing 
needs will be met with internally generated cash flows and financing 
arrangements with lenders, if necessary.

SEASONALITY

         Historically, the Company has not experienced significant seasonality
in its business. The acquisitions of ISOA and INDEX in late 1997, however,
changed the seasonal pattern of revenue and profit, as both companies have
pronounced seasonal patterns in their businesses. The majority of the trade
shows owned by ISOA are held in the second and fourth quarters and, accordingly,
the majority of their revenue is recognized in these quarters. As explained
above, a portion of the Company's revenue growth in the second quarter was due
to the newly acquired ISOA shows. Further, the majority of the INDEX shows have
historically been held in the fourth quarter. Accordingly, the Company
anticipates that these acquisitions will have a positive impact on revenue and
profit as approximately 70% of the annual revenues for these combined shows are
expected to be generated in the fourth quarter of the year.

ACCOUNTING CHANGES

         In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). This statement is required to
be adopted by the Company in the first quarter of 1999. The Company currently
has no derivative instruments and, as such, this statement will not have a
material impact on the Company.

YEAR 2000

General:

         The "Year 2000 Issue" is the result of computer programs that were
written using two digits rather than four to define the applicable year. If the
Company's computer programs with date-sensitive functions are not Year 2000
compliant, they may recognize a date using "00" as the Year 1900 rather than the
Year 2000. This could result in a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary inability
to process transactions, send invoices or engage in similar normal business
activities.

         Penton's Year 2000 Project ("Project") is proceeding as scheduled. Some
of our systems and related software are already Year 2000 compliant, however the
Project is designed to bring the remaining software and systems into Year 2000
compliance in time to minimize any significant detrimental effects on
operations. The Project covers information systems infrastructure, financial and
administrative systems, production and circulation operating systems and
significant vendors and customers.

Project:

         The first component of the Projects it to identify the internal
business systems of the Company and its operating subsidiaries that are
susceptible to system failures or processing errors as a result of the Year 2000
issue. This effort is substantially complete with all business systems
identified and priorities established for repair or replacement. Those systems
considered most critical to continuing operations are being given the highest
priority.

         The second component of the Project involves the actual remediation and
replacement of the various business systems. The Company and its operating
subsidiaries are using both internal and external resources to complete this
process. Systems ranked highest in priority have either been remediated or
replaced or scheduled for remediation or replacement including the replacement
of the primary general ledger and accounts payable systems with programs from a
national software vendor. The implementation of the new systems is in its final
stages and is expected to be completed by year-end. The Company's objective is
to complete substantially all remediation and replacement of internal systems by
July 1999, and to complete final testing



                                       18

<PAGE>   19



and certification for readiness by the end of the third quarter of 1999.

         As part of the second component of the Project, significant service
providers, vendors, suppliers and customers that are believed to be critical to
business operations after January 1, 2000, have been identified and steps are
being undertaken in an attempt to reasonably ascertain their state of Year 2000
readiness through questionnaires, inquiries and other available means. This
process is progressing according to plan.

Costs:

         It is currently estimated that the aggregate incremental cost of the
Company's Project efforts will be approximately $0.3 million to $0.8 million, of
which approximately $0.1 million has been spent. These costs are being expensed
as they are incurred and are being funded through operating cash flow. These
amounts do not include any costs associated with the implementation of
contingency plans, which are in the process of being developed to supplement the
Company's existing Disaster Recovery Plan. The costs associated with the
replacement of computerized systems, hardware or equipment is currently
estimated to be approximately $0.5 million, substantially all of which would be
capitalized, are not included in the above estimates.

Risks:

         The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. Such failures could materially and adversely affect the company's
results of operations, liquidity and financial condition. Due to the general
uncertainty inherent in the Year 2000 problem, resulting in part from the
uncertainty of the Year 2000 readiness of third-party suppliers and customers,
the company is unable to determine at this time whether the consequences of Year
2000 failures will have a material impact on the company's results of
operations, liquidity or financial condition. The Year 2000 Project is expected
to significantly reduce the company's level of uncertainty about the Year 2000
problem and, in particular, about the Year 2000 compliance and readiness of its
material external agents. The company believes that, with the implementation of
new business systems and completion of the Project as scheduled, the possibility
of significant interruptions of normal operations should be reduced.

         The company's Project readiness program is an ongoing process and the
estimates of costs and completion dates for various components of the Project
readiness program described above are subject to change.

         Funds Effective Rate in effect on such day plus 1/2 of 1%. For purposes
         hereof: "PRIME RATE" shall mean, at any time, the rate of interest per
         annum publicly announced from time to time by First Union at its

         change in the Prime Rate shall be effective as of the opening of
         business on the day such change in the Prime Rate occurs. The parties
         hereto acknowledge that the rate announced publicly by First Union as
         its Prime Rate is an index or base rate and shall not necessarily be
         its lowest or best rate charged to its customers or other banks; and
         "FEDERAL FUNDS EFFECTIVE RATE" shall mean, for any day, the weighted
         average of the rates on overnight federal funds transactions with
         members of the Federal Reserve System arranged by federal funds

         Federal Reserve Bank of New York, or, if such rate is not so published
         on the next succeeding Business Day, the average of the quotations for
         the day of such transactions received by the Administrative Agent from
         three federal funds brokers of recognized standing selected by it. If
         for any reason the Administrative Agent shall have determined (which
         determination shall be conclusive in the absence of manifest error)
         that it is unable to ascertain the Federal Funds Effective Rate,
         including the inability or failure of the Administrative Agent to
         obtain sufficient quotations in accordance with the terms thereof, the
         Base Rate shall be determined without regard to clause (b) of the first
         sentence of this definition, as appropriate, until the circumstances
         giving rise to such inability no longer exist. Any change in the Base
         Rate due to a change in the Prime Rate or the Federal Funds Effective
         Rate shall be effective on the opening of business on the date of such
         change.

                  "BASE RATE LOANS": Revolving Loans that bear interest at an
         interest rate based on the Base Rate.

                  "BORROWER" AND "BORROWERS": such terms as defined in the first
         paragraph of this Agreement.

                  "BORROWING DATE": in respect of any Loan, the date such Loan
         is made.

                  "BUSINESS": such term as defined in Section 3.10(b).

                  "BUSINESS DAY": a day other than a Saturday, Sunday or other
         day on which commercial banks in Charlotte, North Carolina or
         Cleveland, Ohio are authorized or required by law to close; PROVIDED,
         HOWEVER, that when used in connection with a rate determination,
         borrowing or payment in respect of a Eurocurrency Loan, the term
         "Business Day" shall also exclude any day on which banks in London,
         England are not open for dealings in Dollar deposits in the London
         interbank market.

shall be interpreted, all accounting determinations hereunder shall be made, and

                  (b)      REVOLVING LOAN BORROWINGS.

                           (i) NOTICE OF BORROWING. Penton USA shall request a
                  Revolving Loan borrowing by written notice (or telephone
                  notice promptly confirmed in writing) to the Agent not later
                  than 11:00 A.M. (Charlotte, North Carolina time) on the

                  the case of Base Rate Loans, and on the third Business Day
                  prior to the date of the requested borrowing in the case of

                  combination thereof, and if Eurocurrency Loans are requested,
                  the Interest Period(s) therefor. If Penton USA shall fail to
                  specify in any such Notice of Borrowing (i) an applicable
                  Interest Period in the case of a Eurocurrency Loan, then such
                  notice shall be deemed to be a request for an Interest Period
                  of one month, or (ii) the Type of Revolving Loan requested,
                  then such notice shall be deemed to be a request for a
                  Eurocurrency Loan for an Interest Period of one month
                  hereunder. The Agent shall give notice to each affected Lender
                  promptly upon receipt of each Notice of Borrowing pursuant to
                  this Section 2.1(b)(i), the contents thereof and each such
                  Lender's share of any borrowing to be made pursuant thereto.

                           (ii) MINIMUM AMOUNTS. Each Revolving Loan made as (A)
                  a Eurocurrency Loan shall be in a minimum aggregate principal
                  amount of $1,000,000 and integral multiples of $1,000,000 in
                  excess thereof and (B) a Base Rate Loan shall be in a minimum
                  aggregate principal amount of $1,000,000 and integral
                  multiples of $500,000 in excess thereof (or if less, the
                  remaining Revolving Committed Amount).

                           (iii) ADVANCES. Each Lender will make its Revolving
                  Commitment Percentage of each Revolving Loan borrowing
                  available to the Agent for the account of Penton USA as
                  specified in Section 2.17(b), or in such other account in the
                  United States as the Agent may specify in writing, by 1:00
                  P.M. (Charlotte, North Carolina time) on the date specified in
                  the applicable Notice of Borrowing in Dollars and in funds
                  immediately available to the Agent. Such borrowing will then
                  be made available to Penton USA by the Agent by crediting the
                  account of Penton USA on the books of such office with the
                  aggregate of the amounts made available to the Agent by the
                  Lenders and in like funds as received by the Agent together
                  with any amounts advanced by the Agent under Section 2.15(b).
                  Penton USA hereby irrevocably authorizes the Administrative
                  Agent to disburse the proceeds of each borrowing requested
                  pursuant to this Section 2.1 in immediately available funds by
                  crediting such proceeds to a deposit account of Penton USA
                  maintained with the Administrative Agent or by wire transfer
                  to any other account

                  of Penton USA in each such case as may be specified by Penton

                  hereto as SCHEDULE 2.1(B)(III) (a "NOTICE OF ACCOUNT
                  DESIGNATION"). Unless otherwise specified by Penton USA, the
                  Notice of Account Designation most recently provided to the
                  Administrative Agent shall control.

                  (c) REPAYMENT. The principal amount of all Revolving Loans
         shall be due and payable in full on the Termination Date.

                  (d) INTEREST. Subject to the provisions of Section 2.3.

                           (i) BASE RATE LOANS. During such periods as Revolving
                  Loans shall be comprised in whole or in part of Base Rate
                  Loans, such Base Rate Loans shall bear interest at a per annum
                  rate equal to the Base Rate;

                           (ii) EUROCURRENCY LOANS. During such periods as
                  Revolving Loans shall be comprised in whole or in part of
                  Eurocurrency Loans, such Eurocurrency Loans shall bear
                  interest at a per annum rate equal to the sum of the
                  Eurocurrency Rate PLUS the Applicable Interest Rate
                  Percentage.

         Interest on Revolving Loans shall be payable in arrears on each
         applicable Interest Payment Date (or at such other times as may be
         specified herein).

                  (e) REVOLVING NOTES. The Revolving Loans shall be evidenced by
         a duly executed Revolving Note in favor of each Lender in substantially
         the form of SCHEDULE 2.1(E). Each Lender is hereby authorized to record
         the date, Type and amount of each Revolving Loan made by such Lender,
         each continuation thereof, each conversion of all or a portion thereof
         to another Type, the date and amount of each payment or prepayment of
         principal thereof and, in the case of Eurocurrency Loans, the length of
         each Interest Period with respect thereto, on the schedule annexed to
         and constituting a part of its Revolving Note, and any such recordation
         shall constitute prima facie evidence of the accuracy of the
         information so recorded absent manifest error; PROVIDED that neither
         the failure to make, nor any error in the making of, any such
         recordation shall limit or otherwise affect the obligation of the
         Borrowers hereunder or under such Revolving Note with respect to any
         Revolving Loan and payments of principal or interest on such Revolving
         Note. Each Revolving Note shall be dated the Closing Date and provide
         for the payment of interest in accordance with subsection 2.1(d).

         2.2      FOREIGN CURRENCY LOAN SUBFACILITY.

         the provisions hereof.

                  (b) FOREIGN CURRENCY LOAN BORROWINGS.

                  to each Lender promptly upon 


                                       25
<PAGE>   31

                  receipt of each Notice of Borrowing, the contents thereof and
                  each such Lender's share of any borrowing to be made pursuant
                  thereto.

                           (ii) MINIMUM AMOUNTS. Each Foreign Currency Loan
                  shall be in a minimum aggregate principal amount equal to the
                  applicable Foreign Currency Equivalent of approximately
                  $1,000,000 and integral multiples of the applicable Foreign
                  Currency Equivalent of approximately $1,000,000 in excess
                  thereof.

                           (iii) ADVANCES. Each Lender will make its Revolving
                  Commitment Percentage of each Foreign Currency Loan borrowing
                  available to the Agent by 1:00 P.M., local time in the place
                  where such deposit is required to be made by the succeeding
                  terms hereof, on the date specified in the applicable Notice
                  of Borrowing by deposit with the Agent, at the same place and
                  same account specified in Section 2.17(b) for payments by
                  Penton UK in the applicable Foreign Currency, of same day
                  funds in the applicable Foreign Currency. Such deposit will be
                  made to such accounts in the primary market for such Foreign
                  Currency as the Agent shall specify from time to time by
                  notice to the Lenders. To the extent funds are received from
                  the Lenders, the Agent shall promptly make such funds
                  available by wire transfer to such accounts as Penton UK shall
                  have specified to the Agent together with any amounts advanced
                  by the Agent under Section 2.15(b).

                  (c) REPAYMENT. The principal amount of all Foreign Currency
         Loans shall be due and payable in full in the applicable Foreign
         Currency on the Termination Date.

                  (d) INTEREST. Subject to the provisions of Section 2.3,
         Foreign Currency Loans shall bear interest at a per annum rate equal to
         the Eurocurrency Rate PLUS the Applicable Interest Rate Percentage.
         Interest on Foreign Currency Loans shall be payable (in the applicable
         Foreign Currency) in arrears on each applicable Interest Payment Date
         (or at such other times as may be specified herein). Any Foreign
         Currency Loan made in British Pounds Sterling shall have added to the
         interest otherwise applicable to such Loan the MLA Cost associated with
         such Loan.

                  (e) FOREIGN CURRENCY NOTES. The Foreign Currency Loans shall
         be evidenced by a Revolving Note duly executed by Penton UK in favor of
         each Lender.

                  (f) MAXIMUM NUMBER OF LOANS. Penton UK will be limited to a
         maximum number of Loans under this Section 2.2 as provided in Section
         2.1(f).

         2.3      DEFAULT RATE.

         Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable on demand, at a per


                                       26
<PAGE>   32

annum rate, in the case of overdue principal, equal to the rate that would
otherwise be applicable thereto plus 2% and in the case of all other over due
amounts, equal to the Base Rate plus 2%.

         2.4      EXTENSION AND CONVERSION.

         Subject to the terms of Section 4.2, a Borrower shall have the option,
on any Business Day, to extend existing Loans into a subsequent permissible
Interest Period or to convert Loans into Loans of another interest rate type;
PROVIDED, HOWEVER, that (i) except as provided in Section 2.11, Eurocurrency
Loans may be converted into Base Rate Loans only on the last day of the Interest
Period applicable thereto, (ii) Eurocurrency Loans may be extended, and Base
Rate Loans may be converted into Eurocurrency Loans, only if no Default or Event
of Default is in existence on the date of extension or conversion and the
conditions set forth in subsections (a), (b), (c) and (d) of Section 4.2 have
been satisfied, (iii) Loans extended as, or converted into, Eurocurrency Loans
shall be subject to the terms of the definition of "INTEREST PERIOD" set forth
in Section 1.1 and shall be in such minimum amounts as provided in, with respect
to Revolving Loans, Section 2.1(b)(ii) or, with respect to Foreign Currency
Loans, Section 2.2(b)(ii), and (iv) any request for extension or conversion of a
Eurocurrency Loan which shall fail to specify an Interest Period shall be deemed
to be a request for an Interest Period of one month. Each such extension or
conversion shall be effected by a Borrower, by giving a Notice of
Extension/Conversion (or telephone notice promptly confirmed in writing) to the
Agent prior to 11:00 A.M. (Charlotte, North Carolina time) on the Business Day
prior to, in the case of the conversion of a Eurocurrency Loan into a Base Rate
Loan, and on the third Business Day prior to (or fourth Business Day prior to,
in the case of a Foreign Currency Loan), in the case of the extension of a
Eurocurrency Loan as, or conversion of a Base Rate Loan into, a Eurocurrency
Loan, the date of the proposed extension or conversion, specifying the date of
the proposed extension or conversion, the Loans to be so extended or converted,
the types of Loans into which such Loans are to be converted and, if
appropriate, the applicable Interest Periods with respect thereto. Each request
for extension or conversion shall be irrevocable and shall constitute a
representation and warranty by the applicable Borrower of the matters specified
in subsections (a), (b), (c) and (d) of Section 4.2. In the event a Borrower
fails to request extension or conversion of any Eurocurrency Loan in accordance
with this Section, or any such conversion or extension is not permitted or
required by this Section, then (i) in the case of any Eurocurrency Loan which is
not a Foreign Currency Loan, such Eurocurrency Loan shall be automatically
converted into a Eurocurrency Loan for an Interest Period of one month at the
end of the Interest Period applicable thereto, and (ii) in the case of any
Foreign Currency Loan, such Eurocurrency Loan shall be automatically continued
as a Eurocurrency Loan in the same Foreign Currency for an Interest Period of
one month. The Agent shall give each Lender notice as promptly as practicable of
any such proposed extension or conversion affecting any Loan.

         2.5      REDUCTIONS AND INCREASE IN COMMITMENTS AND PREPAYMENTS.

                  (a) VOLUNTARY REDUCTION IN REVOLVING COMMITMENT. The Borrowers
         may from time to time permanently reduce the aggregate amount of the
         Revolving Commitments in whole or in part without premium or penalty
         except as provided in 


                                       27
<PAGE>   33

         Section 2.14 upon three (3) Business Days' prior written notice to the
         Agent; PROVIDED that after giving effect to any such voluntary
         reduction the Dollar Amount (determined as of the most recent
         Determination Date) of Revolving Loans and Foreign Currency Loans then
         outstanding shall not exceed the Aggregate Revolving Committed Amount,
         as reduced. Partial reductions in the aggregate Revolving Commitments
         shall in each case be in a minimum aggregate amount of $1,000,000 and
         integral multiples of $1,000,000 in excess thereof.

                  (b) INCREASE IN REVOLVING LOAN COMMITMENTS. The Borrowers
         shall have the right upon at least thirty (30) Business Days' prior
         written notice to the Agent and the Lenders to request an increase the
         Revolving Committed Amount by up to $25,000,000, in a single increase,
         at any time on or after the Closing Date. Approval of such request
         shall be in the sole discretion of the Agent and the Lenders and any
         such increase shall be subject to the following additional conditions:

                           (i) no Default or Event of Default shall have
                  occurred and be continuing on the date on which such Revolving
                  Committed Amount increase is to become effective;

                           (ii) the representations and warranties set forth in
                  Section 3 of this Credit Agreement shall be true and correct
                  in all material respects on and as of the date on which such
                  Revolving Committed Amount increase is to become effective;

                           (iii) on or before the date on which such Revolving
                  Committed Amount increase is to become effective, the Agent
                  shall have received, for its own account, the mutually
                  acceptable fees and expenses required by separate agreement of
                  the Borrowers and the Agent to be paid in connection with such
                  increase;

                           (iv) such Revolving Committed Amount increase shall
                  be an integral multiple of $5,000,000 and shall in no event be
                  less than $5,000,000; and

                           (v) such requested Revolving Committed Amount
                  increase shall be effective on such date only to the extent
                  that, on or before such date, the Agent shall have received
                  and accepted a corresponding amount of additional
                  Commitment(s) pursuant to a commitment letter(s) acceptable to
                  the Agent from one or more Lenders acceptable to the Agent
                  and, with respect to any Lender that is not at such time a
                  Lender hereunder, to the Borrowers.

                  (c) MANDATORY PREPAYMENT ON REVOLVING LOANS. If at any time
         the Dollar Amount (determined as of the most recent Determination Date)
         of Revolving Loans and Foreign Currency Loans then outstanding shall
         exceed the Aggregate Revolving Committed Amount, as reduced from time
         to time, the Borrowers shall immediately 


                                       28
<PAGE>   34

         make payment on the Loans in an amount sufficient to eliminate such
         excess. Any such mandatory prepayments shall be applied first to Loans
         in the currency in which such payment is received, and first to Base
         Rate Loans and then to Eurocurrency Loans in direct order of their
         Interest Period maturities.

                  (d) VOLUNTARY PREPAYMENTS. Loans may be prepaid in whole or in
         part without premium or penalty; PROVIDED that (i) Eurocurrency Loans
         may not be prepaid other than at the end of the Interest Period
         applicable thereto and only then on three (3) Business Days' (four (4)
         Business Days' in the case of Foreign Currency Loans) prior written
         notice to the Agent, (ii) any prepayment of Eurocurrency Loans will be
         subject to Section 2.14, and (iii) each such partial prepayment shall
         be in a minimum aggregate principal Dollar Amount of $1,000,000 and
         integral multiples of $1,000,000 in excess thereof ($500,000 in the
         case of Base Rate Loans). Voluntary prepayments on the Revolving Loans
         may be reborrowed in accordance with the provisions hereof. Any such
         voluntary prepayments shall be applied first to Base Rate Loans and
         then to Eurocurrency Loans in direct order of their Interest Period
         maturities.

                  (e) NOTICE. Except as otherwise provided herein, the Borrowers
         will provide notice to the Agent of any prepayment by 11:00 A.M.
         (Charlotte, North Carolina time) on the day prior to the date of
         prepayment.

         2.6      REPLACEMENT OF LENDERS UNDER CERTAIN CIRCUMSTANCES.

         The Borrowers shall be permitted to replace any Lender which (a)
requests reimbursements for amounts owing pursuant to Section 2.9, 2.12 or 2.13
or (b) defaults in its obligation to make loans under this Agreement, with a
replacement financial institution; provided that (i) such replacement does not
conflict with any applicable Requirement of Law, (ii) no Default of Event of
Default shall have occurred and be continuing, (iii) with respect to clause (a)
hereof, prior to any such replacement, such Lender shall not have eliminated the
continued need for payments of amounts owing pursuant to Section 2.9, 2.12
and/or 2.13, (iv) the replacement financial institution shall purchase, at par,
all Loans and other amounts owing to such replaced Lender on or prior to the
date of replacement, (v) the Borrowers shall be liable to such replaced Lender
under Section 2.14 if any Eurocurrency Loan owing to such replaced Lender shall
be purchased other than on the last day of the Interest Period relating thereto,
(vi) the replacement financial institution, if not already a Lender, shall be
reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender
shall be obligated to make such replacement in accordance with Section 9.6
(provided that the Borrowers or the replacement financial institution shall be
obligated to pay the registration and processing fee referred to therein),
(viii) until such time as such replacement shall be consummated, the Borrowers
shall pay all additional amounts, if any, required pursuant to Section 2.9, 2.12
and/or 2.13, as the case may be, and (ix) in the case of clause (b) above, any
such replacement shall not be deemed to be a waiver of any rights which the
Borrowers, the Administrative Agent or any other Lender shall have against the
replaced Lender.

         2.7      FEES.

                  (a) COMMITMENT FEE. In consideration of the Revolving
         Commitments hereunder, the Borrowers agree to pay to the Agent for the
         ratable benefit of the Lenders an aggregate commitment fee (the
         "COMMITMENT FEE") equal to the Applicable Commitment Fee Percentage per
         annum on the average daily unused amount of the Revolving Committed
         Amount for the applicable period. The Commitment Fee shall accrue from
         the Closing Date and shall be payable quarterly in arrears on the 15th
         day following the last day of each calendar quarter for the immediately
         preceding quarter (or portion thereof) beginning with the first such
         date to occur after the Closing Date.

                  (b) FACILITY FEE. The Borrowers agree to pay to the Agent, for
         its own account, the facility fee (the "FACILITY FEE"), as referred to
         in the Commitment Letter.

         2.8      EUROCURRENCY RESERVE COMPENSATION.

         For so long as any Lender maintains reserves against "Eurocurrency
liabilities" (or any other category of liabilities which includes deposits by
reference to which the interest rate on any Eurocurrency Loans is determined),
and, as a result, the cost to such Lender of making or maintaining any of its
Eurocurrency Loans is increased, then such Lender may require the Borrowers to
pay, contemporaneously with each payment of interest on such Eurocurrency Loans
of such Lender, additional interest at a rate per annum up to but not exceeding
the excess of (i) (A) the applicable Eurocurrency Rate divided by (B) one MINUS
the Eurocurrency Reserve Percentage OVER (ii) the applicable Eurocurrency Rate.
Any Lender wishing to require payment of such additional interest (x) shall so
notify the Borrowers and the Agent, in which case such additional interest on
the Eurocurrency Loans of such Lender shall be payable to such Lender at the
place indicated in such notice with respect to each Interest Period commencing
at least three (3) Business Days after the giving of such notice and (y) shall
furnish to the Borrowers at least five (5) Business Days prior to each date on
which interest is payable on the Eurocurrency Loans a certificate setting forth
the amount to which such Lender is then entitled under this Section 2.8 (which
shall be consistent with such Lender's good faith estimate of the level at which
the related reserves are maintained by it). Each such certificate shall be
accompanied by such information as the Borrowers may reasonably request as to
the computation set forth therein.

         2.9      CAPITAL ADEQUACY.

         If any Lender has determined, that the adoption or the becoming
effective of, or any change in, or any change by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, in the interpretation or administration of any
applicable law, rule or regulation regarding capital adequacy, in each case
after the date hereof, or compliance by such Lender or any controlling
corporation of such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's capital or assets (or that of any controlling
corporation of such 


                                       30
<PAGE>   36

Lender) as a consequence of its commitments or obligations hereunder to a level
below that which such Lender or any controlling corporation of such lender could
have achieved but for such adoption, effectiveness, change or compliance (taking
into consideration such Lender's policies (or those of any controlling
corporation of such Lender) with respect to capital adequacy), then, upon five
Business Days' notice from such Lender to the Borrowers, accompanied by a
certificate from such Lender setting forth the additional amount or amounts to
be paid to it hereunder, the Borrowers shall be obligated to pay to such Lender
such additional amount or amounts as will compensate such Lender or any such
controlling corporation of such Lender for such reduction; provided that the
Borrowers shall not be required to compensate such Lender pursuant to this
Section 2.9 for any reductions incurred more than six months prior to the date
that such Lender notifies the Borrowers of such change in applicable law, rule
or regulation regarding capital adequacy giving rise to such reduction. Each
determination by any such Lender of amounts owing under this Section shall,
absent manifest error, be conclusive and binding on the parties hereto.

         2.10     UNAVAILABILITY.

         In the event, and on each occasion, that on the day that is two (2)
Business Days prior to the commencement of any Interest Period for a
Eurocurrency Loan of any amount, Interest Period or currency, the Agent shall
have determined or shall have been notified by the Majority Lenders (a) that
deposits in the relevant amount in the relevant currency and for the relevant
Interest Period are not available in the relevant market to any Lender, or that
reasonable means do not exist for ascertaining the Eurocurrency Rate for any
such Loan, or (b) that the rates at which such deposits are being offered will
not adequately and fairly reflect the cost to any Lender of making or
maintaining its Eurocurrency Loan during such Interest Period, the Agent shall
promptly give written or telecopy notice of such determination to the Borrowers
and the Lenders. In the event of any such determination, until the Agent shall
have advised the Borrowers and the Lenders that the circumstances giving rise to
such notice no longer exist, any request by a Borrower for a Eurocurrency Loan
of the affected amount, Interest Period or currency, or a conversion to or
continuation of a Eurocurrency Loan of the affected amount, Interest Period or
currency, shall be deemed rescinded. Each determination by the Agent hereunder
shall be conclusive absent manifest error.

         2.11     ILLEGALITY.

                  (a) Notwithstanding any other provision herein, if (i) the
         adoption of or any change in any Requirement of Law or in the
         interpretation or application thereof occurring after the Closing Date
         shall make it unlawful for any Lender to make or maintain any
         Eurocurrency Loan or Foreign Currency Loan, or (ii) there shall have
         occurred any change in national or international financial, political
         or economic conditions (including the imposition of or any change in
         exchange controls) or currency exchange rates which would make it
         impracticable for any Lender to make Loans denominated in any Foreign
         Currency to any Borrower, as contemplated by this Credit Agreement,
         then such Lenders, together with Lenders giving notice under Section
         2.10 


                                       31
<PAGE>   37

         and 2.12, shall be an "AFFECTED LENDER" and by written notice to the
         Borrowers and to the Agent:

                           (i) such Lender may declare that Eurocurrency Loans
                  or Foreign Currency Loans (in the affected currency or
                  currencies), as the case may be, will not thereafter (for the
                  duration of such unlawfulness or impracticability) be made by
                  such Lender hereunder, whereupon any request for a
                  Eurocurrency Loan or Foreign Currency Loan (in the affected
                  currency or currencies), as the case may be, shall, as to such
                  Lender only, (A) if such Loan is not a Foreign Currency Loan,
                  be deemed a request for a Base Rate Loan, unless such
                  declaration shall be subsequently withdrawn and (B) if such
                  Loan is a Foreign Currency Loan, be deemed to have been
                  withdrawn, unless such declaration shall be subsequently
                  withdrawn; and

                           (ii) such Lender may require that all outstanding
                  Eurocurrency Loans or Foreign Currency Loans (in the affected
                  currency or currencies), as the case may be, made by it be (A)
                  if such Loans are not Foreign Currency Loans, converted to
                  Base Rate Loans, in which event all such Eurocurrency Loans
                  shall be automatically converted to Base Rate Loans as of the
                  effective date of such notice as provided in paragraph (b)
                  below or (B) if such Loans are Foreign Currency Loans, repaid
                  immediately, in which event all such Foreign Currency Loans
                  (in the affected currency or currencies) shall be required to
                  be repaid in full by the Borrowers as of the effective date of
                  such notice as provided in paragraph (b) below.

         In the event any Lender shall exercise its rights under (i) or (ii)
         above with respect to any Loans which are not Foreign Currency Loans,
         all payments and prepayments of principal which would otherwise have
         been applied to repay the Eurocurrency Loans that would have been made
         by such Lender or the converted Eurocurrency Loans of such Lender shall
         instead be applied to repay the Base Rate Loans made by such Lender in
         lieu of, or resulting from the conversion, of such Eurocurrency Loans.

                  (b) For purposes of this Section 2.11, a notice to the
         Borrowers by any Lender shall be effective as to each such Loan, if
         lawful, on the last day of the Interest Period currently applicable to
         such Loan; in all other cases such notice shall be effective on the
         date of receipt by the Borrowers.

         2.12     REQUIREMENTS OF LAW.

         If, after the date hereof, the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof applicable to
any Lender, or compliance by any Lender with any request or directive (whether
or not having the force of law) from any central bank or other Governmental
Authority, in each case made subsequent to the Closing Date (or, if later, the
date on which such Lender becomes a Lender):



                                       32
<PAGE>   38

                  (a) shall subject such Lender to any additional tax of any
         kind whatsoever with respect to any Eurocurrency Loans made by it or
         its obligation to make Eurocurrency Loans, or change the basis of
         taxation of payments to such Lender in respect thereof (except for (i)
         Non-Excluded Taxes covered by Section 2.13 (including Non-Excluded
         Taxes imposed solely by reason of any failure of such Lender to comply
         with its obligations under Section 2.13(b)) and (ii) changes in taxes
         measured by or imposed upon the overall net income, or franchise tax
         (imposed in lieu of such net income tax), of such Lender or its
         applicable lending office, branch, or any affiliate thereof));

                  (b) shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         held by, deposits or other liabilities in or for the account of,
         advances, loans or other extensions of credit by, or any other
         acquisition of funds by, any office of such Lender which is not
         otherwise included in the determination of the Eurocurrency Rate
         hereunder or any additional interest payable under Section 2.8; or

                  (c) shall impose on such Lender any other similar condition
         (excluding any tax of any kind whatsoever);

         and the result of any of the foregoing is to increase the cost to such
         Lender, by an amount which such Lender reasonably deems to be material,
         of making, converting into, continuing or maintaining Eurocurrency
         Loans or to reduce any amount receivable hereunder in respect thereof,
         then, in any such case, upon notice to the Borrowers from such Lender,
         through the Agent, in accordance herewith, each Borrower shall be
         obligated to promptly pay such Lender, upon its demand, any additional
         amounts necessary to compensate such Lender for such increased cost or
         reduced amount receivable, PROVIDED that, in any such case other than
         as set forth in clause (b) above, any Borrower may elect to convert the
         Eurocurrency Loans (other than Foreign Currency Loans) made by such
         Lender hereunder to Base Rate Loans by giving the Agent at least one
         Business Day's notice of such election, in which case the applicable
         Borrower shall promptly pay to such Lender, upon demand, without
         duplication, such amounts, if any, as may be required pursuant to
         Section 2.14. If any Lender becomes entitled to claim any additional
         amounts pursuant to this subsection, it shall provide prompt notice
         thereof to the Borrowers, through the Agent, certifying (x) that one of
         the events described in this Section 2.12 has occurred and describing
         in reasonable detail the nature of such event, (y) as to the increased
         cost or reduced amount resulting from such event and (z) as to the
         additional amount demanded by such Lender and a reasonably detailed
         explanation of the calculation thereof; provided that the Borrowers
         shall not be required to compensate such Lender pursuant to this
         Section 2.12 for any increased costs incurred more than six months
         prior to the date that such Lender notifies the Borrowers of such
         change in such Requirement of Law giving rise to such increased costs.
         Such a certificate as to any additional amounts payable pursuant to
         this subsection submitted by such Lender, 


                                       33
<PAGE>   39

         through the Agent, to the Borrowers shall be conclusive and binding on
         the parties hereto in the absence of manifest error. This covenant
         shall survive the termination of this Credit Agreement and the payment
         of the Loans and all other amounts payable hereunder.

         2.13     TAXES.

                  (a) Except as provided below in this subsection, all payments
         made by any Borrower under this Credit Agreement and any Notes shall be
         made free and clear of, and without deduction or withholding for or on
         account of, any present or future income, stamp or other taxes, levies,
         imposts, duties, charges, fees, deductions or withholdings, now or
         hereafter imposed, levied, collected, withheld or assessed by any
         court, or governmental body, agency or other official, excluding: (i)
         taxes measured by or imposed upon the overall net income of any Lender
         or its applicable lending office, or any branch or affiliate thereof,
         and (ii) all franchise taxes, branch taxes, taxes on doing business or
         taxes on the overall capital or net worth of any Lender or its
         applicable lending office, or any branch or affiliate thereof, in each
         case imposed in lieu of net income taxes, imposed (A) by the
         jurisdiction under the laws of which such Lender, applicable lending
         office, branch or affiliate is organized or is located, or in which its
         principal executive office is located, or any nation within which such
         jurisdiction is located or any political subdivision thereof, or (B) by
         reason of any connection between the jurisdiction imposing such tax and
         such Lender, applicable lending office, branch or affiliate other than
         a connection arising solely from such Lender having executed, delivered
         or performed its obligations, or received payment under or enforced,
         this Credit Agreement or any Notes. If any such non-excluded taxes,
         levies, imposts, duties, charges, fees, deductions or withholdings
         ("NON-EXCLUDED TAXES") are required to be withheld from any amounts
         payable to the Agent or any Lender hereunder or under any Notes, (1)
         the amounts so payable to the Agent or such Lender shall be increased,
         subject to subsection (c) of this Section 2.13 to the extent necessary
         to yield to the Agent or such Lender (after payment of all Non-Excluded
         Taxes) interest or any such other amounts payable hereunder at the
         rates or in the amounts specified in this Credit Agreement and any
         Notes, PROVIDED, HOWEVER, that a Borrower shall be entitled to deduct
         and withhold any Non-Excluded Taxes imposed by the United States
         federal government and shall not be required to increase any such
         amounts payable to any Lender that is not organized under the laws of
         the United States of America or a state thereof if such Lender fails to
         comply with the requirements of paragraph (b) of this subsection
         whenever any such Non-Excluded Taxes are payable by such Borrower, and
         (2) as promptly as possible thereafter such Borrower shall send to the
         Agent for its own account or for the account of such Lender, as the
         case may be, a certified copy of an original official receipt received
         by such Borrower showing payment thereof. If a Borrower fails to pay
         any Non-Excluded Taxes when due to the appropriate taxing authority or
         fails to remit to the Agent the required receipts or other required
         documentary evidence, such Borrower shall indemnify the Agent and the
         Lenders for any incremental taxes, interest or penalties that may
         become payable by the Agent or any Lender as a result of any such
         failure. The agreements in this subsection 


                                       34
<PAGE>   40

         shall survive the termination of this Credit Agreement and the payment
         of the Loans and all other amounts payable hereunder.

                  (b) Each Lender that is not incorporated under the laws of the
         United States of America or a state thereof shall:

                           (X)(i) on or before the date of any payment by a
                  Borrower under this Credit Agreement or Notes to such Lender,
                  deliver to the Borrowers and the Agent (A) two (2) duly
                  completed copies of United States Internal Revenue Service
                  Form 1001 or 4224, or successor applicable form, as the case
                  may be, certifying that it is entitled to receive payments
                  under this Credit Agreement and any Notes without deduction or
                  withholding of any United States federal income taxes and (B)
                  an Internal Revenue Service Form W-8 or W-9, or successor
                  applicable form, as the case may be, certifying that it is
                  entitled to an exemption from United States backup withholding
                  tax;

                           (ii) deliver to the Borrowers and the Agent two (2)
                  further copies of any such form or certification on or before
                  the date that any such form or certification expires or
                  becomes obsolete and after the occurrence of any event
                  requiring a change in the most recent form previously
                  delivered by it to the Borrowers; and

                           (iii) obtain such extensions of time for filing and
                  complete such forms or certifications as may reasonably be
                  requested by the Borrowers or the Agent; or

                           (Y) Each Lender or transferee that is not a "bank"
                  under Section 881(c)(3)(A) of the Internal Revenue Code
                  thereof shall:

                           (i) on or before the date it becomes a party to this
                  Credit Agreement (or, in the case of a participant, on or
                  before the date such participant becomes a participant
                  hereunder), deliver to the Borrowers and the Agent (i) a
                  statement under penalties of perjury that such Lender or
                  transferee (x) is not a "bank" under Section 881(c)(3)(A) of
                  the Internal Revenue Code, is not subject to regulatory or
                  other legal requirements as a bank in any jurisdiction, and
                  has not been treated as a bank for purposes of any tax,
                  securities law or other filing or submission made to any
                  Governmental Authority, any application made to a rating
                  agency or qualification for any exemption from tax, securities
                  law or other legal requirements, (y) is not a 10-percent
                  shareholder within the meaning of Section 811(c)(3)(B) of the
                  Internal Revenue Code and (z) is not a controlled foreign
                  corporation receiving interest from a related person within
                  the meaning of Section 881(c)(3)(C) of the Internal Revenue
                  Code and (ii) a properly completed and duly executed Internal
                  Revenue Service Form W-8 or applicable successor form;



                                       35
<PAGE>   41

                           (ii) deliver to the Borrowers and the Agent two
                  further properly completed and duly executed copies of such
                  Form W-8 expires or becomes obsolete or after the occurrence
                  of any event requiring a change in the most recent form
                  previously delivered by it to the Borrowers or upon the
                  request of the Borrowers; and

                           (iii) obtain such extensions of time for filing and
                  completing such forms or certifications as may be reasonably
                  requested by the Borrowers or the Agent;

         unless in any such case any change in treaty, law or regulation has
         occurred after the date such Person becomes a Lender hereunder which
         renders all such forms inapplicable or which would prevent such Lender
         from duly completing and delivering any such form with respect to it
         and such Lender so advises the Borrowers and the Agent.

                  (c) Each Lender shall, as soon as is reasonably practicable
         after the Closing Date, file a form FD 13 with the United States
         Internal Revenue Service in relation to payments made or to be made by
         Penton UK under this Credit Agreement and any Foreign Currency Loans.
         If the United States Internal Revenue Service determines that the form
         FD 13 filed by such Lender does not establish that the Lender is
         entitled to receive payments made by Penton UK under this Credit
         Agreement, the Foreign Currency Loans and the Revolving Note as at the
         date of delivery thereof without deduction or withholding of English
         withholding taxes or, if the Inland Revenue requires proof of such
         entitlement, such Lender shall, within forty-five (45) days after a
         written request from Penton UK, offer such reasonable assistance as
         Penton UK may request in order to establish such Lender's entitlement
         (if any) to receive payments made by Penton UK under this Credit
         Agreement, any Foreign Currency Loans and the Revolving Note without
         deduction or withholding of English withholding taxes. Penton UK shall
         not be required pursuant to subsection (a) of this Section 2.13 to
         increase any amounts payable to any Lender because of any deduction or
         withholding of English withholding taxes required by English law (and
         Penton UK, if required by law to do so, shall be entitled to withhold
         such amounts and pay such amounts to the government of England) if the
         obligation to make such deduction or withholding would not have arisen
         but for the Lender not being entitled (pursuant to any applicable tax
         treaty or otherwise) to receive payments made by Penton UK under this
         Agreement, any Foreign Currency Loans and the Revolving Note executed
         in its favor or the failure by such Lender to provide Penton UK and the
         United States Internal Revenue Center with the requested forms or other
         reasonable assistance.

                  (d) Each Lender agrees to make a good faith effort to minimize
         any Non-Excluded Taxes by making, funding or maintaining its Foreign
         Currency Loans through another lending office located in another
         jurisdiction so long as the making, funding or maintenance of such
         Foreign Currency Loans through such other office does not, in the
         reasonable judgment of such Lender, materially affect such Lender;
         provided that any 


                                       36
<PAGE>   42

         Lender which is unable or unwilling to fund its Foreign Currency Loans
         through a branch of such Lender in England will so notify the
         Borrowers.

                  (e) Each Person that shall become a Lender or a participant of
         a Lender pursuant to subsection 9.6 shall, upon the effectiveness of
         the related transfer, be required to provide all of the forms,
         certifications and statements required pursuant to this subsection,
         PROVIDED that in the case of a participant of a Lender the obligations
         of such participant of a Lender pursuant to subsection (b) shall be
         determined as if the participant of a Lender were a Lender except that
         such participant of a Lender shall furnish all such required forms,
         certifications and statements to the Lender from which the related
         participation shall have been purchased.

         2.14     INDEMNITY.

         Each Borrower promises to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur (other
than through such Lender's gross negligence or willful misconduct and except as
set forth in Sections 2.10 and 2.11) as a consequence of (a) default by such
Borrower in making a borrowing of, conversion into or continuation of
Eurocurrency Loans after such Borrower has given a notice requesting the same in
accordance with the provisions of this Credit Agreement, (b) default by such
Borrower in making any prepayment of a Eurocurrency Loan after such Borrower has
given a notice thereof in accordance with the provisions of this Credit
Agreement or (c) the making of a prepayment of Eurocurrency Loans on a day which
is not the last day of an Interest Period with respect thereto. With respect to
Eurocurrency Loans, such indemnification shall be an amount equal to the excess,
if any, of (i) the amount of interest which would have accrued on the amount so
prepaid, or not so borrowed, converted or continued, for the period from the
date of such prepayment or of such failure to borrow, convert or continue to the
last day of the applicable Interest Period (or, in the case of a failure to
borrow, convert or continue, the Interest Period that would have commenced on
the date of such failure) in each case at the applicable rate of interest for
such Eurocurrency Loans provided for herein (excluding, however, the Applicable
Interest Rate Percentage included therein, if any) over (ii) the amount of
interest (as reasonably determined by such Lender) which would have accrued to
such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurocurrency market. The covenants of
each Borrower set forth in this Section 2.14 shall survive the termination of
this Credit Agreement and the payment of the Loans and all other amounts payable
hereunder.

         2.15     PRO RATA TREATMENT.

         Except to the extent otherwise provided herein:

                  (a) LOANS. Each of the Revolving Loans and Foreign Currency
         Loans and payments of principal, interest and fees (including the
         Commitment Fee) on or in respect thereof and each reduction in the
         Revolving Commitments relating thereto, and each


                                       37
<PAGE>   43

         conversion or extension of such Loans and obligations shall be
         allocated pro rata among the Lenders in accordance with the respective
         principal amounts of their outstanding Revolving Loans and Foreign
         Currency Loans.

                  (b) ADVANCES. Unless the Agent shall have been notified in
         writing by any Lender prior to a borrowing that such Lender will not
         make the amount that would constitute its ratable share of such
         borrowing available to the Agent, the Agent may assume that such Lender
         is making such amount available to the Agent, and the Agent may, in
         reliance upon such assumption, make available to a Borrower a
         corresponding amount. If such amount is not made available to the Agent
         by such Lender within the time period specified therefor hereunder,
         such Lender shall pay to the Agent, on demand, such amount with
         interest thereon (or, in the case of a Foreign Currency Loan interest
         on the daily Dollar Equivalent thereof) at a rate equal to the Federal
         Funds Effective Rate for the period until such Lender makes such amount
         immediately available to the Agent. A certificate of the Agent
         submitted to any Lender with respect to any amounts owing under this
         subsection shall be conclusive in the absence of manifest error.

         2.16     SHARING OF PAYMENTS.

         Subject to the terms of Section 2.15 hereof, the Lenders agree among
themselves that, in the event that any Lender shall obtain payment in respect of
any Loan or any other obligation owing to such Lender under this Credit
Agreement through the exercise of a right of setoff, banker's lien or
counterclaim, or pursuant to a secured claim under Section 506 of the Bankruptcy
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable bankruptcy, insolvency or
other similar law or otherwise, or by any other means, in excess of its pro rata
share of such payment as provided for in this Credit Agreement, such Lender
shall promptly purchase from the other Lenders a participation in such Loans and
other obligations in such amounts, and make such other adjustments from time to
time, as shall be equitable to the end that all Lenders share such payment in
accordance with their respective ratable shares as provided for in this Credit
Agreement. The Lenders further agree among themselves that if payment to a
Lender obtained by such Lender through the exercise of a right of setoff,
banker's lien, counterclaim or other event as aforesaid shall be rescinded or
must otherwise be restored, each Lender which shall have shared the benefit of
such payment shall, by repurchase of a participation theretofore sold, return
its share of that benefit (together with its share of any accrued interest
payable with respect thereto) to each Lender whose payment shall have been
rescinded or otherwise restored. Each Borrower agrees that any Lender so
purchasing such a participation may, to the fullest extent permitted by law,
exercise all rights of payment, including setoff, banker's lien or counterclaim,
with respect to such participation as fully as if such Lender were a holder of
such Loan or other obligation in the amount of such participation. Except as
otherwise expressly provided in this Credit Agreement, if any Lender or the
Agent shall fail to remit to the Agent or any other Lender an amount payable by
such Lender or the Agent to the Agent or such other Lender pursuant to this
Credit Agreement on the date when such amount is due, such payments shall be
made together with interest thereon for each date from the date such amount is
due until the date such 


                                       38
<PAGE>   44

amount is paid to the Agent or such other Lender at a rate per annum equal to
the Federal Funds Effective Rate. If under any applicable bankruptcy, insolvency
or other similar law, any Lender receives a secured claim in lieu of a setoff to
which this Section 2.16 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders under this Section 2.16 to share in the benefits of
any recovery on such secured claim.

         2.17     PAYMENTS, COMPUTATIONS, ETC.

                  (a) CURRENCY OF PAYMENTS. Each payment on account of an amount
         due from any Credit Party hereunder or under any other Credit Document
         shall be made by such Credit Party to the Agent for the PRO RATA
         account of the Lenders entitled to receive such payment as provided
         herein in the currency in which such amount is denominated and in such
         funds as are customary at the place and time of payment for the
         settlement of international payments in such currency. Without limiting
         the terms of the preceding sentence, accrued interest on any Loans
         denominated in a Foreign Currency shall be payable in the same Foreign
         Currency as such Loan. Upon request, the Agent will give the Credit
         Parties a statement showing the computation used in calculating such
         amount, which statement shall be conclusive in the absence of manifest
         error. The obligation of each Credit Party to make each payment on
         account of such amount in the currency in which such amount is
         denominated shall not be discharged or satisfied by any tender, or any
         recovery pursuant to any judgment, which is expressed in or converted
         into any other currency, except to the extent such tender or recovery
         shall result in the actual receipt by the Agent of the full amount in
         the appropriate currency payable hereunder. Each Credit Party agrees
         that its obligation to make each payment on account of such amount in
         the currency in which such amount is denominated shall be enforceable
         as an additional or alternative claim for recovery in such currency of
         the amount (if any) by which such actual receipt shall fall short of
         the full amount of such currency payable hereunder, and shall not be
         affected by judgment being obtained for such amount.

                  (b) PLACE AND MANNER OF PAYMENTS. Except as otherwise
         specifically provided herein, all payments hereunder shall be made to
         the Agent in immediately available funds, without offset, deduction,
         counterclaim or withholding of any kind, prior to 12:00 noon, local
         time in the place where such payment is required to be made pursuant to
         this subsection (b), on the date due at:

         with respect to payment in Dollars:

         or at such other place as may be designated by the Agent to the
         Borrowers in writing. Any payments received after such time shall be
         deemed received on the next succeeding Business Day. The Agent may, but
         shall not be obligated to, charge any account of any Borrower at the
         Agent for the payment when due of all amounts payable by the Borrowers
         hereunder. Each Borrower shall, at the time it makes any payment under
         this Credit Agreement, specify to the Agent the Loans, Fees, interest
         or other amounts payable by such Borrower hereunder to which such
         payment is to be applied (and in the event that it fails so to specify,
         or if such application would be inconsistent with the terms hereof, the
         Agent shall distribute such payment to the Lenders in such manner as
         the Agent may reasonably determine to be appropriate in respect of
         obligations owing by such Borrower hereunder, subject to the terms of
         Section 2.15(a)). The Agent shall promptly remit in same day funds to
         each Lender such Lender's share, if any, of payments received by the
         Agent for the account of such Lender. Whenever any payment hereunder
         shall be stated to be due on a day which is not a Business Day, the due
         date thereof shall be extended to the next succeeding Business Day
         (subject to accrual of interest and Fees for the period of such
         extension), except that in the case of Eurocurrency Loans, if the
         extension would cause the payment to be made in the next following
         calendar month, then such payment shall instead be made on the next
         preceding Business Day. Except as expressly provided otherwise herein,
         all computations of interest and fees shall be made based on a year of
         365 or 366 days, as appropriate. All computations of interest on
         Eurocurrency Loans and Foreign Currency Loans (other than Loans made in
         British Pounds Sterling) shall be based on a year of 360 days for the
         actual days elapsed. Interest shall accrue from and include the date of
         borrowing, but exclude the date of payment.

                  (c) ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.
         Notwithstanding any other provisions of this Credit Agreement to the
         contrary, after the occurrence and during the continuance of an Event
         of Default, all amounts collected or received by the Agent or any
         Lender on account of the Obligations or any other amounts outstanding
         under any of the Credit Documents or in respect of the Collateral shall
         be paid over or delivered as follows:



                                       40
<PAGE>   46

                  FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation reasonable attorneys' fees)
         of the Agent in connection with enforcing the rights of the Lenders
         under the Credit Documents;

                  SECOND, to payment of any fees owed to the Agent;

                  THIRD, to the payment of all reasonable out-of-pocket costs
         and expenses, (including without limitation, reasonable attorneys'
         fees) of each of the Lenders in connection with enforcing its rights
         under the Credit Documents or otherwise with respect to the Obligations
         owing to such Lender;

                  FOURTH, to the payment of all accrued interest and fees in
         respect of the Obligations;

                  FIFTH, to the payment of the outstanding principal amount of
         the Obligations;

                  SIXTH, to all other Obligations and other obligations which
         shall have become due and payable under the Credit Documents or
         otherwise and not repaid pursuant to clauses "FIRST" through "FIFTH"
         above; and

                  SEVENTH, to the payment of the surplus, if any, to whoever may
         be lawfully entitled to receive such surplus.

         In carrying out the foregoing, (i) amounts received shall be applied in
         the numerical order provided until exhausted prior to application to
         the next succeeding category; and (ii) each of the Lenders shall
         receive an amount equal to its pro rata share (based on the proportion
         that the then outstanding Loans held by such Lender bears to the
         aggregate then outstanding Loans) of amounts available to be applied
         pursuant to clauses "THIRD", "FOURTH", "FIFTH" and "SIXTH" above.

         2.18     CHANGE OF CURRENCY.

                  (a) If more than one currency or currency unit is at any time
         recognized by the Bank of England as the lawful currency of the United
         Kingdom, then (i) any reference in the Credit Documents to, and any
         obligations arising under the Credit Documents in, British Pounds
         Sterling, shall be translated into, or paid in, the currency or
         currency unit designated by the Agent on behalf of the Lenders and (ii)
         any translation from one currency or currency unit to another shall be
         at the official rate of exchange recognized by the Bank of England for
         the conversion of that currency or currency unit into the other,
         rounded up or down by the Administrative Agent on behalf of the Lenders
         acting reasonably.

                  (b) If a change in British Pounds Sterling occurs (including,
         without limitation, in consequence of European monetary union), this
         Agreement will be 


                                       41
<PAGE>   47

         amended as specified by the Agent on behalf of the Lenders to reflect
         the change in currency and to put the Lenders in the same position, as
         far as possible, as they would have been had no change in currency
         occurred.


                    SECTION 3. REPRESENTATIONS AND WARRANTIES

         To induce the Lenders to enter into this Agreement and to make the
Loans herein provided for, the Borrowers hereby represent and warrant to the
Administrative Agent and to each Lender that:

         3.1      FINANCIAL CONDITION.

         The financial statements provided to the Administrative Agent and the
Lenders, consisting of an audited balance sheet of the Borrowers dated as of
December 31, 1997, together with related statements of operations and statements
of cash flows, copies of which have heretofore been provided to each of the
Lenders, are complete and correct in all material respects and present fairly in
all material respects in accordance with GAAP the financial condition and pro
forma results from operations of the entities for the periods specified, except
as noted therein and subject to normal year-end adjustments and the footnote
disclosures required by GAAP.

         3.2      NO CHANGE.

         Since December 31, 1997, there has been no development or event which
has had a Material Adverse Effect.

         3.3      EXISTENCE; COMPLIANCE WITH LAW.

         Each of the Borrowers and each Subsidiary (a) is organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization, (b) has the limited liability company, corporate or partnership
power and authority and the legal right to own and operate all its material
property, to lease the material property it operates as lessee and to conduct
the business in which it is currently engaged, (c) is qualified as a foreign
limited liability company, corporation or partnership and in good standing under
the laws of each jurisdiction where its ownership, lease or operation of
property or the conduct of its business requires such qualification except to
the extent that the failure to so qualify or be in good standing would not, in
the aggregate, have a Material Adverse Effect and (d) is in compliance with all
applicable Requirements of Law except to the extent that the failure to comply
therewith would not, in the aggregate, reasonably be expected to have a Material
Adverse Effect.

         3.4      POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS.

         Each of the Borrowers and each Subsidiary has the corporate, limited
liability company or partnership power and authority and the legal right to
make, deliver and perform the Credit 


                                       42
<PAGE>   48

Documents to which it is party and has taken all necessary company, corporate or
partnership action to authorize the execution, delivery and performance by it of
the Credit Documents to which it is party. No consent or authorization of,
filing with, notice to or other act by or in respect of, any Governmental
Authority or any other Person is required in connection with the borrowings
hereunder or with the execution, delivery or performance of any Credit Document
by the Borrowers or any Subsidiary (other than those which have been obtained)
or with the validity or enforceability of any Credit Document against the
Borrowers or any Subsidiary (except such filings as are necessary in connection
with the perfection of the Liens created by such Credit Documents) except to the
extent that the failure to obtain any such consent or authorization or to affect
any filing or notice would not in the aggregate, reasonably be expected to have
a Material Adverse Effect. Each Credit Document to which the Borrowers or any
Subsidiary is a party has been duly executed and delivered on behalf of the
Borrowers or such Subsidiary. Each Credit Document to which it is a party
constitutes a legal, valid and binding obligation of the Borrowers or such
Subsidiary enforceable against the Borrowers or such Subsidiary in accordance
with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or
similar laws affecting the enforcement of creditors' rights generally and by
general equitable principles (whether enforcement is sought by proceedings in
equity or at law).

         3.5      NO LEGAL BAR; NO DEFAULT.

         The execution, delivery and performance of the Credit Documents, the
borrowings thereunder and the use of the proceeds of the Loans will not violate
any Requirement of Law or any Contractual Obligation of the Borrowers or any
Subsidiary (except those as to which waivers or consents have been obtained and
except for any such violation which would not reasonably be expected to have a
Material Adverse Effect), and will not result in, or require, the creation or
imposition of any Lien on any of their respective properties or revenues
pursuant to any Requirement of Law or Contractual Obligation other than the
Liens arising under or contemplated in connection with the Credit Documents.
Neither of the Borrowers nor any Subsidiary is in default under or with respect
to any of its Contractual Obligations in any respect which would reasonably be
expected to have a Material Adverse Effect. No Default or Event of Default has
occurred and is continuing.

         3.6      NO MATERIAL LITIGATION.

         Except as set forth in SCHEDULE 3.6, no litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the best knowledge of the Borrowers, threatened by or against the Borrowers
or any Subsidiary or against any of its or their respective properties or
revenues (a) with respect to the Credit Documents or any Loan or any of the
transactions contemplated hereby, or (b) which could reasonably be expected to
have a Material Adverse Effect.

         3.7      INVESTMENT COMPANY ACT.

         Neither of the Borrowers nor any Subsidiary is an "investment company",
or a company "controlled" by an "investment company", within the meaning of the
Investment Company Act of 1940, as amended.

         3.8      FEDERAL REGULATIONS.

         No part of the proceeds of any Loan hereunder will be used directly or
indirectly for any purpose which violates, or which would be inconsistent with,
the provisions of Regulation G, T, U or X of the Board of Governors of the
Federal Reserve System as now and from time to time hereafter in effect. Neither
of the Borrowers nor any Subsidiary owns "margin stock" except as identified in
the financial statements referred to in Section 3.1 and the aggregate value of
all "margin stock" owned by the Borrowers and the Subsidiaries taken as a group
does not exceed 25% of the value of their assets.

         3.9      ERISA.

         Neither a Reportable Event nor an "accumulated funding deficiency"
(within the meaning of Section 412 of the Code or Section 302 of ERISA) has
occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code, except to the extent that any such occurrence or failure to comply
would not reasonably be expected to have a Material Adverse Effect. No
termination of a Single Employer Plan has occurred resulting in any liability
that has not been satisfied, and no Lien in favor of the PBGC or a Plan has
arisen, during such five-year period which would reasonably be expected to have
a Material Adverse Effect. The present value of all accrued benefits under each
Single Employer Plan (based on those assumptions used to fund such Plans) did
not, as of the last annual valuation date prior to the date on which this
representation is made or deemed made, exceed the value of the assets of such
Plan allocable to such accrued benefits by an amount which, as determined in
accordance with GAAP, would reasonably be expected to have a Material Adverse
Effect. Neither of the Borrowers, nor any Subsidiary, nor any Commonly
Controlled Entity is currently subject to any liability for a complete or
partial withdrawal from a Multiemployer Plan which would reasonably be expected
to have a Material Adverse Effect.

         3.10     ENVIRONMENTAL MATTERS.

         Except to the extent that all of the following, in the aggregate, would
not reasonably be expected to have a Material Adverse Effect:

                  (a) To the best knowledge of the Borrowers, the facilities and
         properties owned, leased or operated by the Borrowers and their
         Subsidiaries (the "PROPERTIES") do not use, store, generate, dispose of
         or handle any Materials of Environmental Concern in



                                       44
<PAGE>   50

         amounts or concentrations which could reasonably be expected to give
         rise to liability under any applicable Environmental Law.

                  (b) To the best knowledge of the Borrowers, the Properties and
         all operations at the Properties are in material compliance, and have
         in the last five years been in compliance, in all material respects
         with all applicable Environmental Laws, and there has been no material
         violation of any Environmental Law with respect to the Properties or
         the business operated by the Borrowers (the "BUSINESS").

                  (c) Neither of the Borrowers nor any Subsidiary has received
         any notice of violation, alleged violation, non-compliance, liability
         or potential liability regarding environmental matters or compliance
         with Environmental Laws with regard to any of the Properties or the
         Business, nor do the Borrowers have knowledge that any such notice is
         being threatened.

                  (d) To the best knowledge of the Borrowers, all Materials of
         Environmental Concern at, on or under any of the Properties have been
         generated, treated, stored or disposed of in accordance with applicable
         Environmental Law.

                  (e) No judicial proceeding or governmental or administrative
         action is pending or, to the best of the knowledge of the Borrowers,
         threatened, under any Environmental Law to which either of the
         Borrowers or any Subsidiary is or will be named as a party with respect
         to the Properties or the Business or any facility that has received
         Materials of Environmental Concern generated by the Borrowers, nor are
         there any consent decrees or other decrees, consent orders,
         administrative orders or other orders, or other administrative or
         judicial requirements outstanding under any Environmental Law with
         respect to the Properties or the Business.

                  (f) To the best knowledge of the Borrowers, there has been no
         release of Materials of Environmental Concern at or from the Properties
         arising from or related to the Business or the operations of the
         Borrowers or any Subsidiary in connection with the Properties, in
         violation of or in amounts or in a manner that could reasonably be
         expected to give rise to liability under applicable Environmental Laws.

         3.11     PURPOSE OF LOAN.

         The proceeds of the Loans will be used to finance the acquisition of
the Acquired Assets and closing costs incurred in connection therewith, to repay
existing Indebtedness, to pay closing costs incurred in connection herewith and
to provide senior debt capacity to make acquisitions and investments permitted
hereby and to provide general working capital.

         3.12     SUBSIDIARIES.

         Set forth on SCHEDULE 3.12 is a complete and accurate list of all
Subsidiaries of the Borrowers as of the Closing Date. As of the Closing Date,
information on the attached Schedule includes state of organization; the number
of shares of each class of capital stock or partnership or other equity
interests (identified by type) outstanding; the number and percentage of
outstanding shares of each class of stock or percentage of ownership interest;
and the number and effect, if exercised, of all outstanding options, warrants,
rights of conversion or purchase and similar rights. The outstanding capital
stock and partnership and other equity interests of all such Subsidiaries are
validly issued, fully paid and non-assessable and are owned, free and clear of
all Liens (other than those arising under or contemplated in connection with the
Credit Documents). As of the Closing Date, except as set forth on SCHEDULE 3.12,
there are no outstanding options or other rights pertaining to the partnership
or other equity interests of the Borrowers, and no voting trusts, shareholders'
or partners' agreements (other than the partnership agreements relating to the
formation, organization, operation and governance of the partnerships, copies of
which have been provided to the Administrative Agent and the Lenders) or similar
agreement affecting either ownership of or the right to vote such partnership
interests.

         3.13     INTELLECTUAL PROPERTY RIGHTS.

         The Borrowers and their Subsidiaries own or have the right to use,
subject to any of its obligations under any valid and binding license agreement,
the Intellectual Property (as defined below) disclosed in SCHEDULE 3.13 hereto,
which, to the best of their knowledge, represents all Intellectual Property
individually or in the aggregate material to the conduct of the businesses of
the Borrowers and their Subsidiaries taken as a whole on the date hereof. Except
as disclosed in SCHEDULE 3.13 hereto or where the failure shall not have a
Material Adverse Effect, (i) each of the Borrowers or a Subsidiary has the right
to use the Intellectual Property disclosed in SCHEDULE 3.13 hereto in perpetuity
and without payment of royalties, (ii) all registrations with and applications
to Governmental Authorities in respect of such Intellectual Property are valid
and in full force and effect and are not subject to the payment of any taxes or
maintenance fees or the taking of any other actions by the Borrowers or a
Subsidiary to maintain their validity or effectiveness, and (iii) there are no
restrictions on the direct or indirect transfer of any Contractual Obligation,
or any interest therein, held by the Borrowers or any Subsidiary in respect of
such Intellectual Property. Neither the Borrowers nor any Subsidiary of the
Borrowers is in default (or with the giving of notice or lapse of time or both,
would be in default) under any license to use such Intellectual Property the
loss of which would reasonably be expected to have a Material Adverse Effect To
the best of the Borrowers' and their Subsidiaries' knowledge none of the
Intellectual Property is being infringed by any third party the loss of which
may have a Material Adverse Effect, and to the best of the Borrowers' and their
Subsidiaries' knowledge neither the Borrowers nor any Subsidiary of the
Borrowers is infringing any Intellectual Property of any third party the
infringement of which would reasonably be expected to have a Material Adverse
Effect. For purposes of this Section 3.13, "INTELLECTUAL PROPERTY" means patents
and patent rights, trademarks and trademark rights, trade names and trade name
rights, service marks and service mark rights, copyrights and copyright rights,
including the right to sue for past 


                                       46
<PAGE>   52

infringement, licenses, proprietary information, designs, processes, inventions,
software and related intellectual property rights and all pending applications
for and registrations of any of the foregoing.

         3.14     NO BURDENSOME RESTRICTIONS.

         No applicable Requirement of Law known to the Borrowers or Contractual
Obligation of the Borrowers could reasonably be expected to have a Material
Adverse Effect.

         3.15     TAXES.

         The Borrowers and their Subsidiaries have filed, or caused to be filed,
all material tax returns (Federal, state, local and foreign) required to be
filed on or prior to the Closing Date and paid all taxes shown thereon to be due
(including interest and penalties) and have paid all other taxes, fees,
assessments and other governmental charges (including mortgage recording taxes,
documentary stamp taxes and intangibles taxes) owing (or necessary to preserve
any Liens in favor of the Lenders) with respect to taxable periods ending on or
before the Closing Date by them, except for such taxes (i) which are not yet
delinquent, (ii) as are being contested in good faith and by proper proceedings,
and against which adequate reserves are being maintained in accordance with GAAP
or (iii) the nonpayment of which would not, in the aggregate, reasonably be
expected to have a Material Adverse Effect. The Borrowers are not aware of any
proposed material tax assessments against it or any of their Subsidiaries.

         3.16     NO INTEREST IN REAL ESTATE.

         Other than the fee simple interests and leasehold interests reflected
on SCHEDULE 3.16, neither the Borrowers nor any of their Subsidiaries has any
interest in any real property.

Agreement, the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein and in the other
Credit Documents, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or otherwise exist against the Administrative Agent.

         8.2      DELEGATION OF DUTIES.

         The Administrative Agent may execute any of its duties under this
Agreement by or through agents or attorneys-in-fact and shall be entitled to
rely on advice of counsel concerning all matters pertaining to such duties. The
Administrative Agent shall not be responsible for the negligence or misconduct
of any agents or attorneys-in-fact selected by it with reasonable care. Without
limiting the foregoing, the Administrative Agent may appoint an affiliate as its
agent to perform the functions of the Administrative Agent hereunder relating to
the advancing of funds to the Borrowers and distribution of funds to the Lenders
and to perform such other related functions of the Administrative Agent
hereunder as are reasonably incidental to such functions. No such appointment
shall relieve the Administrative Agent of its responsibilities hereunder.

         8.3      EXCULPATORY PROVISIONS.

         Neither the Administrative Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (a) liable for any
action lawfully taken or omitted to be taken by it or such Person under or in
connection with this Agreement (except for its or such Person's own gross
negligence or willful misconduct) or (b) responsible in any manner to any of the
Lenders for any recitals, statements, representations or warranties made by the
Borrowers or 


                                       64
<PAGE>   70

any officer thereof contained in this Agreement or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or for the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
any of the Credit Documents or for any failure of the Borrowers to perform their
Obligations hereunder or thereunder. The Administrative Agent shall not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance by the Borrowers of any of the agreements contained in, or
conditions of, this Agreement, or to inspect the properties, books or records of
the Borrowers.

         8.4      RELIANCE BY ADMINISTRATIVE AGENT.

         The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any Note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation reasonably believed
by it to be genuine and correct and to have been signed, sent or made by the
proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Borrowers), independent
accountants and other experts selected by the Administrative Agent. The
Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless (a) a written notice of assignment, negotiation
or transfer thereof shall have been filed with the Administrative Agent and (b)
the Administrative Agent shall have received the written agreement of such
assignee to be bound hereby as fully and to the same extent as if such assignee
were an original Lender party hereto, in each case in form satisfactory to the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement unless it shall
first receive such advice or concurrence of the Majority Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred it by reason of
taking or continuing to take any such action. The Administrative Agent shall in
all cases be fully protected in acting, or in refraining from acting, under any
of the Credit Documents in accordance with a request of the Majority Lenders,
and such request and any action taken or failure to act pursuant thereto shall
be binding upon all the Lenders and all future holders of the Notes.

         8.5      NOTICE OF DEFAULT.

         The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent has received notice from a Lender or the Borrowers
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
prompt notice thereof to each of the Lenders. The Administrative Agent shall
take such action with respect to such Default or Event of Default as shall be
directed by the Majority Lenders, including, without limitation, exercise of
remedies and initiation of litigation; PROVIDED, HOWEVER, that unless and until
the Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking 


                                       65
<PAGE>   71

such action, with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the Lenders.

         8.6      NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its officers, directors, employees, agents, attorneys-in-fact
or affiliates has made any representation or warranty to it and that no act by
the Administrative Agent hereinafter taken, including any review of the affairs
of the Borrowers, shall be deemed to constitute any representation or warranty
by the Administrative Agent to any Lender. Each Lender represents to the
Administrative Agent that it has, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrowers and made its own decision to
make its Loans hereunder and enter into this Agreement. Each Lender also
represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial and other condition
and creditworthiness of the Borrowers. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Borrowers which may come into
the possession of the Administrative Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates.

         8.7      INDEMNIFICATION.

         The Lenders agree to indemnify the Administrative Agent in its capacity
hereunder (to the extent not reimbursed by the Borrowers and without limiting
the obligation of the Borrowers to do so), ratably according to their respective
Commitment Percentages in effect on the date on which indemnification is sought
under this subsection, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever which may at any time (including, without
limitation, at any time following the payment of the Notes) be imposed on,
incurred by or asserted against the Administrative Agent in any way relating to
or arising out of any Credit Document or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by the Administrative Agent under or in
connection with any of the foregoing; PROVIDED, HOWEVER, that no Lender shall be
liable for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
to the extent resulting from the Administrative Agent's gross negligence or
willful misconduct. The agreements in this 


                                       66
<PAGE>   72

subsection shall survive the termination of this Agreement and payment of the
Notes and all other amounts payable hereunder.

         8.8      ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.

         The Administrative Agent and its affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Borrowers as
though the Administrative Agent were not the Administrative Agent hereunder.
With respect to its Loans made or renewed by it and any Note issued to it, the
Administrative Agent shall have the same rights and powers under this Agreement
as any Lender and may exercise the same as though it were not the Administrative
Agent, and the terms "Lender" and "Lenders" shall include the Administrative
Agent in its individual capacity.

         8.9      SUCCESSOR ADMINISTRATIVE AGENT.

         The Administrative Agent may resign or be removed as Administrative
Agent upon 30 days' prior notice to the Borrowers and the Lenders. The
Administrative Agent may be removed by the written consent of the Majority
Lenders. If the Administrative Agent shall resign or be removed as
Administrative Agent under this Agreement and the Notes, then the Majority
Lenders shall appoint from among the Lenders a successor agent for the Lenders,
which successor agent shall be approved by the Borrowers, or if the Majority
Lenders cannot agree on a successor within 30 days from the notice of
resignation by the Administrative Agent, the Administrative Agent, with the
approval of the Borrowers, may appoint a bank or trust company with capital and
surplus of at least $500,000,000 as successor Administrative Agent within 30
days thereafter, whereupon such successor agent shall succeed to the rights,
powers and duties of the Administrative Agent, and the term "Administrative
Agent" shall mean such successor agent effective upon such appointment and
approval, and the former Administrative Agent's rights, powers and duties as
Administrative Agent shall be terminated, without any other or further act or
deed on the part of such former Administrative Agent or any of the parties to
this Agreement or any holders of the Notes. After any retiring Administrative
Agent's resignation or renewal as Administrative Agent, the provisions of this
subsection shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement. Resignation
by the Administrative Agent shall become effective upon appointment of, and
acceptance by, a successor Administrative Agent, or the passage of the
applicable periods without appointment of a successor.


                            SECTION 9. MISCELLANEOUS

         9.1      AMENDMENTS, WAIVERS AND RELEASE OF COLLATERAL.

         Neither this Agreement, nor any of the Notes, nor any of the other
Credit Documents, nor any terms hereof or thereof may be amended, supplemented,
waived or modified except in accordance with the provisions of this subsection.
The Majority Lenders affected thereby may, 


                                       67
<PAGE>   73

or, with the written consent of the Majority Lenders affected thereby, the
Administrative Agent may, from time to time, (a) enter into with the Borrowers
written amendments, supplements or modifications hereto and to the other Credit
Documents for the purpose of adding any provisions to this Agreement or the
other Credit Documents or (b) waive, on such terms and conditions as the
Majority Lenders may specify in such instrument, any of the requirements of this
Agreement or the other Credit Documents or any Default or Event of Default and
its consequences; PROVIDED, HOWEVER, that no such waiver and no such amendment,
waiver, supplement, modification or release shall (i) reduce the amount or
extend the scheduled final date of maturity of any Loan or Note or any
installment thereon, or reduce the stated rate of any interest or fee payable
hereunder or extend the scheduled date of any payment thereof or increase the
amount or extend the expiration date of any Lender's Commitment, in each case
without the written consent of each Lender directly affected thereby, or (ii)
amend, modify or waive any provision of this subsection or reduce the percentage
specified in the definition of Majority Lenders, or consent to the assignment or
transfer by the Borrowers of any of its rights and obligations under this
Agreement, in each case without the written consent of all the Lenders, or (iii)
amend, modify or waive any provision of Section 8 without the written consent of
the then Administrative Agent, or (iv) release all or substantially all of the
collateral, if any, or any Guarantor, without the written consent of all of the
Lenders except to the extent such releases are provided for in this Agreement or
the other Credit Documents, including, without limitation, pursuant to Section
6.5(a) hereof. Any such waiver, any such amendment, supplement or modification
and any such release shall apply equally to each of the Lenders and shall be
binding upon the Borrowers, the Lenders, the Administrative Agent and all future
holders of the Notes. In the case of any waiver, the Borrowers, the Lenders and
the Administrative Agent shall be restored to their former position and rights
hereunder and under the outstanding Loans and Notes and other Credit Documents,
and any Default or Event of Default waived shall be deemed to be cured and not
continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon.

         9.2      NOTICES.

         Except as otherwise provided in Section 2, all notices, requests and

         9.4      SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

         All representations and warranties made hereunder and in any document,
certificate or statement delivered pursuant hereto or in connection herewith
shall survive the execution and delivery of this Agreement and the Notes and the

modification to, the Credit Documents and any other documents prepared in
connection herewith or therewith, and the consummation and administration of the

         9.6      SUCCESSORS AND ASSIGNS; PARTICIPATIONS; PURCHASING LENDERS.

                  (a) This Agreement shall be binding upon and inure to the
         benefit of the Borrowers, the Lenders, the Administrative Agent, all
         future holders of the Notes and their respective successors and
         assigns, except that the Borrowers may not assign or transfer any of
         its rights or obligations under this Agreement or the other Credit
         Documents without the prior written consent of each Lender.

                  (b) Any Lender may, in the ordinary course of its commercial
         banking business and in accordance with applicable law, at any time
         sell to one or more banks or other entities ("PARTICIPANTS")
         participating interests in any Loan owing to such Lender, any Note held
         by such Lender, any Commitment of such Lender, or any other interest of
         such Lender hereunder, PROVIDED, HOWEVER, that in the case of any
         Participant that is not a bank or savings and loan association, no
         transaction described in this Section 9.6(b) may be consummated until
         such Participant demonstrates to the reasonable satisfaction of the
         Borrowers that such transaction will not constitute a prohibited
         transaction under Section 406 of ERISA or Section 4975 of the Code. In
         the event of any such sale by a Lender of participating interests to a
         Participant, such Lender's obligations under this Agreement to the
         other parties to this Agreement shall remain unchanged, such Lender
         shall remain solely responsible for the performance thereof, such
         Lender shall remain the holder of any such Note for all purposes under
         this Agreement, and the Borrowers and the Administrative Agent shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under this Agreement. No
         Lender shall transfer or grant any participation under which the
         Participant shall have rights to approve any amendment to or waiver of
         this Agreement or any other Credit Document except to the extent such
         amendment or waiver would (i) extend the final maturity of any Loan or
         Note in which such Participant is participating, or reduce the stated
         rate or extend the time of payment of interest or Fees thereon (except
         in connection with a waiver of interest at the increased post-default
         rate) or reduce the principal amount thereof, or increase the amount of
         the Participant's participation over the amount thereof then in effect
         (it being understood that a waiver of any Default or Event of Default
         shall not constitute a change in the terms of such participation, and
         that an increase in any Commitment or Loan shall be permitted without
         consent of any Participant if the Participant's participation is not
         increased as a result thereof), (ii) except as otherwise expressly
         provided in a Credit Document, release all or substantially all of the
         collateral, if any, or (iii) consent to the assignment or transfer by
         the Borrowers of any of its rights and obligations under this
         Agreement. In the case of any such participation, the Participant shall
         not have any rights under this Agreement or any of the other Credit
         Documents (the Participant's rights against such Lender in respect of
         such participation to be those set forth in the agreement executed by
         such Lender in favor of the Participant relating thereto) and all
         amounts payable by the Borrowers hereunder shall be determined as if
         such Lender had not sold such participation, PROVIDED that each
         Participant shall be entitled to the benefits of Sections 2.13, 2.14
         and 9.5 with respect to its participation in the Commitments and the
         Loans outstanding from time to time; PROVIDED, that no


                                       71
<PAGE>   77

         Participant shall be entitled to receive any greater amount pursuant to
         such subsections than the transferor Lender would have been entitled to
         receive in respect of the amount of the participation transferred by
         such transferor Lender to such Participant had no such transfer
         occurred.

                  (c) Any Lender may, in the ordinary course of its commercial
         banking business and in accordance with applicable law, at any time
         sell or assign to any Lender or any affiliate thereof and, with the
         consent of the Administrative Agent, and, so long as no Event of
         Default has occurred and is continuing, with the consent of the
         Borrowers (in each case, which consent shall not be unreasonably
         withheld), to one or more additional banks or financial institutions
         ("PURCHASING LENDERS"), all or any part of its rights and obligations
         under this Agreement and the Notes in minimum amounts of $5,000,000 and
         minimum increments of $1,000,000 in excess thereof (or, if less, the
         entire amount of such Lender's obligations) if the Purchasing Lender is
         not a Lender hereunder, or with no minimum amount if the Purchasing
         Lender is a Lender hereunder, pursuant to a Commitment Transfer
         Supplement, executed by such Purchasing Lender, such transferor Lender
         (and, in the case of a Purchasing Lender that is not then a Lender or
         an affiliate thereof, by the Administrative Agent and, so long as no
         Event of Default has occurred and is continuing, by the Borrowers), and
         delivered to the Administrative Agent for its acceptance and recording
         in the Register; provided that at no time shall there be more than a
         total of five (5) Lenders. Each such assignment must be of a constant,
         not varying, percentage of all of such Lender's rights and obligations
         hereunder. Upon such execution, delivery, acceptance and recording,
         from and after the Transfer Effective Date specified in such Commitment
         Transfer Supplement, (x) the Purchasing Lender thereunder shall be a
         party hereto and, to the extent provided in such Commitment Transfer
         Supplement, have the rights and obligations of a Lender hereunder with
         a Commitment as set forth therein, and (y) the transferor Lender
         thereunder shall, to the extent provided in such Commitment Transfer
         Supplement, be released from its obligations under this Agreement (and,
         in the case of a Commitment Transfer Supplement covering all or the
         remaining portion of a transferor Lender's rights and obligations under
         this Agreement, such transferor Lender shall cease to be a party
         hereto). Such Commitment Transfer Supplement shall be deemed to amend
         this Agreement to the extent, and only to the extent, necessary to
         reflect the addition of such Purchasing Lender and the resulting
         adjustment of Commitment Percentages arising from the purchase by such
         Purchasing Lender of all or a portion of the rights and obligations of
         such transferor Lender under this Agreement and the Notes. On or prior
         to the Transfer Effective Date specified in such Commitment Transfer
         Supplement, the Borrowers shall execute and deliver to the
         Administrative Agent in exchange for the Note delivered to the
         Administrative Agent pursuant to such Commitment Transfer Supplement a
         new Note to the order of such Purchasing Lender in an amount equal to
         the Commitment assumed by it pursuant to such Commitment Transfer
         Supplement and, unless the transferor Lender has not retained a
         Commitment hereunder, a new Note to the order of the transferor Lender
         in an amount equal to the Commitment retained by it hereunder. Such new
         Note shall be dated the Closing Date and shall otherwise be in the form
         of the Note replaced 


                                       72
<PAGE>   78

         thereby. The Note surrendered by the transferor Lender shall be
         returned by the Administrative Agent to the Borrowers marked
         "canceled".

                  (d) The Administrative Agent shall maintain at its address
         referred to in Section 9.2 a copy of each Commitment Transfer
         Supplement delivered to it and a register (the "REGISTER") for the
         recordation of the names and addresses of the Lenders and the
         Commitment of, and principal amount of the Loans owing to, each Lender
         from time to time. The entries in the Register shall be conclusive, in
         the absence of manifest error, and the Borrowers, the Administrative
         Agent and the Lenders may treat each Person whose name is recorded in
         the Register as the owner of the Loan recorded therein for all purposes
         of this Agreement. The Register shall be available for inspection by
         the Borrowers or any Lender at any reasonable time and from time to
         time upon reasonable prior notice.

                  (e) Upon its receipt of a Commitment Transfer Supplement
         executed by a transferor Lender and a Purchasing Lender (and, in the
         case of a Purchasing Lender that is not then a Lender or an affiliate
         thereof, by the Administrative Agent and, so long as no Event of
         Default has occurred and is continuing, by the Borrowers) together with
         payment to the Administrative Agent (by the transferor Lender or the
         Purchasing Lender, as agreed between them) of a registration and
         processing fee of $3,000 for each Purchasing Lender listed in such
         Commitment Transfer Supplement, and the Notes subject to such
         Commitment Transfer Supplement, the Administrative Agent shall (i)
         accept such Commitment Transfer Supplement, (ii) record the information
         contained therein in the Register and (iii) give prompt notice of such
         acceptance and recordation to the Lenders and the Borrowers.

                  (f) The Borrowers authorize each Lender to disclose to any
         Participant or Purchasing Lender (each, a "TRANSFEREE") and any
         prospective Transferee any and all financial information in such
         Lender's possession concerning the Borrowers and their Affiliates which
         has been delivered to such Lender by or on behalf of the Borrowers
         pursuant to this Agreement or which has been delivered to such Lender
         by or on behalf of the Borrowers in connection with such Lender's
         credit evaluation of the Borrowers and its Affiliates prior to becoming
         a party to this Agreement; in each case subject to Section 9.15.

                  (g) At the time of each assignment pursuant to this Section
         9.6 to a Person which is not already a Lender hereunder and which is
         not a United States person (as such term is defined in Section
         7701(a)(30) of the Code) for Federal income tax purposes, the
         respective assignee Lender shall provide to the Borrowers and the
         Administrative Agent the appropriate Internal Revenue Service Forms
         described in Section 2.13.

                  (h) Nothing herein shall prohibit any Lender from pledging or
         assigning any of its rights under this Agreement (including, without
         limitation, any right to payment of 


                                       73
<PAGE>   79

         principal and interest under any Note) to any Federal Reserve Bank in
         accordance with applicable laws.

         9.7      ADJUSTMENTS; SET-OFF.

                  (a) Each Lender agrees that if any Lender (a "BENEFITTED
         LENDER") shall at any time receive any payment of all or part of its
         Loans, or interest thereon, or receive any collateral in respect
         thereof (whether voluntarily or involuntarily, by set-off, pursuant to
         events or proceedings of the nature referred to in clause (e) of
         Section 7, or otherwise) in a greater proportion than any such payment
         to or collateral received by any other Lender, if any, in respect of
         such other Lender's Loans, or interest thereon, such benefitted Lender
         shall purchase for cash from the other Lenders a participating interest
         in such portion of each such other Lender's Loan, or shall provide such
         other Lenders with the benefits of any such collateral, or the proceeds
         thereof, as shall be necessary to cause such benefitted Lender to share
         the excess payment or benefits of such collateral or proceeds ratably
         with each of the Lenders; PROVIDED, HOWEVER, that if all or any portion
         of such excess payment or benefits is thereafter recovered from such
         benefitted Lender, such purchase shall be rescinded, and the purchase
         price and benefits returned, to the extent of such recovery, but
         without interest. The Borrowers agree that each Lender so purchasing a
         portion of another Lender's Loans may exercise all rights of payment
         (including, without limitation, rights of set-off) with respect to such
         portion as fully as if such Lender were the direct holder of such
         portion.

                  (b) In addition to any rights and remedies of the Lenders
         provided by law (including, without limitation, other rights of
         set-off), each Lender shall have the right, without prior notice to the
         Borrowers, any such notice being expressly waived by the Borrowers to
         the extent permitted by applicable law, upon the occurrence of any
         Event of Default, to setoff and appropriate and apply any and all
         deposits (general or special, time or demand, provisional or final), in
         any currency, and any other credits, indebtedness or claims, in any
         currency, in each case whether direct or indirect, absolute or
         contingent, matured or unmatured, at any time held or owing by such
         Lender or any branch or agency thereof to or for the credit or the
         account of the Borrowers, or any part thereof in such amounts as such
         Lender may elect, against and on account of the obligations and
         liabilities of the Borrowers to such Lender hereunder and claims of
         every nature and description of such Lender against the Borrowers, in
         any currency, whether arising hereunder, under the Notes or under any
         documents contemplated by or referred to herein or therein, as such
         Lender may elect, whether or not such Lender has made any demand for
         payment and although such obligations, liabilities and claims may be
         contingent or unmatured. The aforesaid right of set-off may be
         exercised by such Lender against the Borrowers or against any trustee
         in bankruptcy, debtor in possession, assignee for the benefit of
         creditors, receiver or execution, judgment or attachment creditor of
         the Borrowers, or against anyone else claiming through or against the
         Borrowers or any such trustee in bankruptcy, debtor in possession,
         assignee for the benefit of creditors, receiver, or execution, judgment
         or attachment creditor, notwithstanding the fact that such right of


                                       74
<PAGE>   80

         set-off shall not have been exercised by such Lender prior to the
         occurrence of any Event of Default. Each Lender agrees promptly to
         notify the Borrowers and the Administrative Agent after any such
         set-off and application made by such Lender; PROVIDED, HOWEVER, that
         the failure to give such notice shall not affect the validity of such
         set-off and application.

         9.8      TABLE OF CONTENTS AND SECTION HEADINGS.

         The table of contents and the Section and subsection headings herein
are intended for convenience only and shall be ignored in construing this
Agreement.

         9.9      COUNTERPARTS.

         This Agreement may be executed by one or more of the parties to this
Agreement on any number of separate counterparts, and all of said counterparts
taken together shall be deemed to constitute one and the same instrument. A set
of the copies of this Agreement signed by all the parties shall be lodged with
the Borrowers and the Administrative Agent.

         9.10     SEVERABILITY.

         Any provision of this Agreement which is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         9.11     INTEGRATION.

         This Agreement, the Notes and the other Credit Documents represent the
agreement of the Borrowers, the Administrative Agent and the Lenders with

representations or warranties by the Administrative Agent, the Borrowers or any
Lender relative to the subject matter hereof not expressly set forth or referred
to herein or in the Notes. Upon execution and delivery of this Agreement, except
with respect to the payment of Fees, the Commitment Letter shall cease to be of
any further force and effect.

         9.13     CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

         All judicial proceedings brought against the Borrowers and/or any other
Credit Party with respect to this Agreement, any Note or any of the other Credit
Documents may be brought in the courts of the State of North Carolina in
Mecklenburg County or of the United States for the Western District of North
Carolina and, by execution and delivery of this Agreement, each of the Borrowers
and the other Credit Parties accepts, for itself and in connection with its
properties, generally and unconditionally, the non-exclusive jurisdiction of the
aforesaid courts and irrevocably agrees to be bound by any final judgment
rendered thereby in connection with this Agreement from which no appeal has been
taken or is available. Each of the Borrowers and the other Credit Parties
irrevocably agrees that all service of process in any such proceedings in any
such court may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to it at its
address set forth in Section 9.2 or at such other address of which the Agent
shall have been notified pursuant thereto, such service being hereby
acknowledged by the each of the Borrowers and the other Credit Parties to be
effective and binding service in every respect. Each of the Borrowers, the other
Credit Parties, the Agent and the Lenders irrevocably waives any objection,
including, without limitation, any objection to the laying of venue or based on
the grounds of forum non conveniens which it may now or hereafter have to the
bringing of any such action or proceeding in any such jurisdiction. Nothing
herein shall affect the right to serve process in any other manner permitted by
law or shall limit the right of any Lender or the Agent to bring proceedings
against the Borrowers or the other Credit Parties in the court of any other
jurisdiction.

         9.14     ARBITRATION.

                  (a) Notwithstanding the provisions of Section 9.13 to the
         contrary, upon demand of any party hereto, whether made before or after
         institution of any judicial proceeding (but in no event more than 90
         days after the institution of any such judicial proceeding), any
         dispute, claim or controversy arising out of, connected with or
         relating to this Agreement and other Credit Documents ("Disputes")
         between or among parties to this Agreement shall be resolved by binding
         arbitration as provided herein. Institution of a judicial proceeding by
         a party does not waive the right of that party to demand arbitration
         hereunder. Disputes may include, without limitation, tort claims,
         counterclaims, disputes as to whether a matter is subject to
         arbitration, claims arising from Credit Documents executed in the
         future, or claims arising out of or connected with the transaction
         reflected by this Agreement.

                  Arbitration shall be conducted under and governed by the
         Commercial Arbitration Rules (the "Arbitration Rules") of the American
         Arbitration Association (the "AAA") and Title 9 of the U.S. Code as
         currently in effect. All arbitration hearings shall be conducted in
         Charlotte, North Carolina. A hearing shall begin within 90 days of
         demand for arbitration and all hearings shall be concluded within 120
         days of demand for arbitration. These time limitations may not be
         extended unless a party shows cause for extension and then no more than
         a total extension of 60 days. The expedited procedures


                                       76
<PAGE>   82

         set forth in Rule 51 ET SEQ. of the Arbitration Rules shall be
         applicable to claims of less than $1,000,000. All applicable statutes
         of limitation shall apply to any Dispute. A judgment upon the award may
         be entered in any court having jurisdiction. Arbitrators shall be
         licensed attorneys selected from the Commercial Financial Dispute
         Arbitration Panel of the AAA. The parties hereto do not waive
         applicable Federal or state substantive law except as provided herein.
         Notwithstanding the foregoing, this arbitration provision does not
         apply to disputes under or related to Interest Rate Protection
         Agreements.

                  (b) Notwithstanding the preceding binding arbitration
         provisions, the Agent, the Lenders, the Borrowers and the other Credit
         Parties agree to preserve, without diminution, certain remedies that
         the Agent on behalf of the Lenders may employ or exercise freely,
         independently or in connection with an arbitration proceeding or after
         an arbitration action is brought. The Agent on behalf of the Lenders
         shall have the right to proceed in any court of proper jurisdiction or
         by self-help to exercise or prosecute the following remedies, as
         applicable (i) all rights of self-help including peaceful occupation of
         real property and collection of rents, set-off, and peaceful possession
         of personal property; and (ii) obtaining provisional or ancillary
         remedies including injunctive relief, sequestration, garnishment,
         attachment, appointment of receiver and filing an involuntary
         bankruptcy proceeding. Preservation of these remedies does not limit
         the power of an arbitrator to grant similar remedies that may be
         requested by a party in a Dispute. Any claim or controversy with regard
         to any party's entitlement to such remedies is a Dispute.

                  (c) The parties hereto agree that they shall not have a remedy
         of punitive or exemplary damages against the other in any Dispute and
         hereby waive any right or claim to punitive or exemplary damages they
         have now or which may arise in the future in connection with any
         Dispute whether the Dispute is resolved by arbitration or judicially.

                  (d) By execution and delivery of this Agreement, each of the
         parties hereto accepts, for itself and in connection with its
         properties, generally and unconditionally, the non-exclusive
         jurisdiction relating to any arbitration proceedings conducted under
         the Arbitration Rules in Charlotte, North Carolina and irrevocably
         agrees to be bound by any final judgment rendered thereby in connection
         with this Agreement from which no appeal has been taken or is
         available.

         9.15     CONFIDENTIALITY.

         The Administrative Agent and each of the Lenders agrees that it will
use reasonable and customary efforts not to disclose without the prior consent
of the Borrowers (other than to its employees, Subsidiaries, Affiliates,
auditors or counsel or to another Lender) any information with respect to the
Borrowers and their Subsidiaries which is furnished pursuant to this Agreement,
any other Credit Document or any documents contemplated by or referred to herein
or therein and which is designated by the Borrowers to the Lenders in writing as
confidential or as to which it is otherwise reasonably clear such information is
not public, except that any Lender may disclose any such information (a) as has
become generally available to the public


                                       77
<PAGE>   83

other than by a breach of this Section 9.15, (b) as may be required or
appropriate in any report, statement or testimony submitted to any municipal,
state or federal regulatory body having or claiming to have jurisdiction over
such Lender or to the Federal Reserve Board or the Federal Deposit Insurance
Corporation or the OCC or similar organizations (whether in the United States or
elsewhere) or their successors or the National Association of Insurance
Commissioners, (c) as may be required or appropriate in response to any summons
or subpoena or any law, order, regulation or ruling applicable to such Lender or
(d) to any prospective Participant or assignee in connection with any
contemplated transfer pursuant to Section 9.6, PROVIDED that such prospective
transferee shall have been made aware of this Section 9.15 and shall have agreed
to be bound by its provisions as if it were a party to this Agreement.

         9.16     ACKNOWLEDGMENTS.

         The Borrowers hereby acknowledge that:

                  (a) each has been advised by counsel in the negotiation,
         execution and delivery of each Credit Document;

                  (b) neither the Administrative Agent nor any Lender has any
         fiduciary relationship with or duty to either of the Borrowers arising
         out of or in connection with this Agreement and the relationship
         between Administrative Agent and Lenders, on one hand, and the
         Borrowers, on the other hand, in connection herewith is solely that of
         debtor and creditor; and

                  (c) no joint venture exists among the Lenders or among either
         of the Borrowers and the Lenders.


                              SECTION 10. GUARANTY

         10.1     THE GUARANTY.

         In order to induce the Lenders to enter into this Agreement and to
extend credit hereunder and in recognition of the direct benefits to be received
by the Guarantors from the Loans hereunder, each of the Guarantors hereby agrees
with the Administrative Agent and the Lenders as follows: each Guarantor hereby
unconditionally and irrevocably jointly and severally guarantees as primary
obligor and not merely as surety the full and prompt payment when due, whether
upon maturity, by acceleration or otherwise, of any and all indebtedness of the
Borrowers to the Administrative Agent and the Lenders and all other Obligations
of the Borrowers and the other Credit Parties hereunder (excluding in the case
of Penton USA, in its capacity as a Guarantor, any obligations of Penton USA
under this Credit Agreement or the Notes, in its capacity as a Borrower). If any
or all of the indebtedness of the Borrowers to the Administrative Agent and the
Lenders becomes due and payable hereunder, each Guarantor unconditionally
promises to pay such indebtedness to the Administrative Agent and the Lenders,


                                       78
<PAGE>   84

or order, on demand, together with any and all reasonable expenses which may be
incurred by the Administrative Agent or the Lenders in collecting any of the
indebtedness. The word "indebtedness" is used in this Section 10 in its most
comprehensive sense and includes any and all advances, debts, obligations and
liabilities of the Borrowers arising in connection with this Agreement, in each
case, heretofore, now, or hereafter made, incurred or created, whether
voluntarily or involuntarily, absolute or contingent, liquidated or
unliquidated, determined or undetermined, whether or not such indebtedness is
from time to time reduced, or extinguished and thereafter increased or incurred,
whether the Borrowers may be liable individually or jointly with others, whether
or not recovery upon such indebtedness may be or hereafter become barred by any
statute of limitations, and whether or not such indebtedness may be or hereafter
become otherwise unenforceable.

         Notwithstanding any provision to the contrary contained herein or in
any other of the Credit Documents, to the extent the obligations of a Guarantor
shall be adjudicated to be invalid or unenforceable for any reason (including,
without limitation, because of any applicable state or federal law relating to
fraudulent conveyances or transfers) then the obligations of each such Guarantor
hereunder shall be limited to the maximum amount that is permissible under
applicable law (whether federal or state and including, without limitation, the
Bankruptcy Code).

         10.2     BANKRUPTCY.

         Additionally, each of the Guarantors unconditionally and irrevocably
guarantees jointly and severally the payment of any and all indebtedness of the
Borrowers to the Lenders whether or not due or payable by the Borrowers upon the
occurrence of any of the events specified in Section 7(a), and unconditionally
promises to pay such indebtedness to the Administrative Agent for the account of
the Lenders, or order, on demand, in lawful money of the United States. Each of
the Guarantors further agrees that to the extent that the Borrowers or a
Guarantor shall make a payment or a transfer of an interest in any property to
the Administrative Agent or any Lender, which payment or transfer or any part
thereof is subsequently invalidated, declared to be fraudulent or preferential,
or otherwise is avoided, and/or required to be repaid to the Borrowers or a
Guarantor, the estate of the Borrowers or a Guarantor, a trustee, receiver or
any other party under any bankruptcy law, state or federal law, common law or
equitable cause, then to the extent of such avoidance or repayment, the
obligation or part thereof intended to be satisfied shall be revived and
continued in full force and effect as if said payment had not been made.

         10.3     NATURE OF LIABILITY.

         The liability of each Guarantor hereunder is exclusive and independent
of any security for or other guaranty of the indebtedness of the Borrowers
whether executed by any such Guarantor, any other guarantor or by any other
party, and no Guarantor's liability hereunder shall be affected or impaired by
(a) any direction as to application of payment by the Borrowers or by any other
party, or (b) any other continuing or other guaranty, undertaking or maximum
liability of a guarantor or of any other party as to the indebtedness of the
Borrowers, or (c) any payment on or in reduction of any such other guaranty or
undertaking, or (d) any dissolution, termination or 


                                       79
<PAGE>   85

increase, decrease or change in personnel by the Borrowers, or (e) any payment
made to the Administrative Agent or the Lenders on the indebtedness which the
Administrative Agent or such Lenders repay the Borrowers pursuant to court order
in any bankruptcy, reorganization, arrangement, moratorium or other debtor
relief proceeding, and each of the Guarantors waives any right to the deferral
or modification of its obligations hereunder by reason of any such proceeding.

         10.4     INDEPENDENT OBLIGATION.

         The obligations of each Guarantor hereunder are independent of the
obligations of any other guarantor or the Borrowers, and a separate action or
actions may be brought and prosecuted against each Guarantor whether or not
action is brought against any other guarantor or the Borrowers and whether or
not any other Guarantor or the Borrowers is joined in any such action or
actions.

         10.5     AUTHORIZATION.

         Each of the Guarantors authorizes the Administrative Agent and each
Lender without notice or demand (except as shall be required by applicable
statute and cannot be waived), and without affecting or impairing its liability
hereunder, from time to time to (a) renew, compromise, extend, increase,
accelerate or otherwise change the time for payment of, or otherwise change the
terms of the indebtedness or any part thereof in accordance with this Agreement,
including any increase or decrease of the rate of interest thereon, (b) take and
hold security from any guarantor or any other party for the payment of this
Guaranty or the indebtedness and exchange, enforce waive and release any such
security, (c) apply such security and direct the order or manner of sale thereof
as the Administrative Agent and the Lenders in their discretion may determine
and (d) release or substitute any one or more endorsers, guarantors, the
Borrowers or other obligors.

         10.6     RELIANCE.

         It is not necessary for the Administrative Agent or the Lenders to
inquire into the capacity or powers of the Borrowers or the officers, directors,
partners or Administrative Agents acting or purporting to act on its behalf, and
any indebtedness made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

         10.7     WAIVER.

                  (a) Each of the Guarantors waives any right (except as shall
         be required by applicable statute and cannot be waived) to require the
         Administrative Agent or any Lender to (i) proceed against the
         Borrowers, any other guarantor or any other party, (ii) proceed against
         or exhaust any security held from the Borrowers, any other guarantor or
         any other party, or (iii) pursue any other remedy in the Administrative
         Agent's or any Lender's power whatsoever. Each of the Guarantors waives
         any defense based on or 


                                       80
<PAGE>   86

         arising out of any defense of the Borrowers, any other guarantor or any
         other party other than payment in full of the indebtedness, including
         without limitation any defense based on or arising out of the
         disability of the Borrowers, any other guarantor or any other party, or
         the unenforceability of the indebtedness or any part thereof from any
         cause, or the cessation from any cause of the liability of the
         Borrowers other than payment in full of the indebtedness. The
         Administrative Agent or any of the Lenders may, at their election,
         foreclose on any security held by the Administrative Agent or a Lender
         by one or more judicial or nonjudicial sales, whether or not every
         aspect of any such sale is commercially reasonable (to the extent such
         sale is permitted by applicable law), or exercise any other right or
         remedy the Administrative Agent and any Lender may have against the
         Borrowers or any other party, or any security, without affecting or
         impairing in any way the liability of any Guarantor hereunder except to
         the extent the indebtedness has been paid. Each of the Guarantors
         waives any defense arising out of any such election by the
         Administrative Agent and each of the Lenders, even though such election
         operates to impair or extinguish any right of reimbursement or
         subrogation or other right or remedy of the Guarantors against the
         Borrowers or any other party or any security.

                  (b) Each of the Guarantors waives all presentments, demands
         for performance, protests and notices, including without limitation
         notices of nonperformance, notice of protest, notices of dishonor,
         notices of acceptance of this Guaranty, and notices of the existence,
         creation or incurring of new or additional indebtedness. Each Guarantor
         assumes all responsibility for being and keeping itself informed of the
         Borrowers' financial condition and assets, and of all other
         circumstances bearing upon the risk of nonpayment of the indebtedness
         and the nature, scope and extent of the risks which such Guarantor
         assumes and incurs hereunder, and agrees that neither the
         Administrative Agent nor any Lender shall have any duty to advise such
         Guarantor of information known to it regarding such circumstances or
         risks.

                  (c) Each of the Guarantors hereby agrees it will not exercise
         any rights of subrogation which it may at any time otherwise have as a
         result of this Guaranty (whether contractual, under Section 509 of the
         U.S. Bankruptcy Code, or otherwise) to the claims of the Lenders
         against the Borrowers or any other guarantor of the indebtedness of the
         Borrowers owing to the Lenders (collectively, the "OTHER PARTIES") and
         all contractual, statutory or common law rights of reimbursement,
         contribution or indemnity from any Other Party which it may at any time
         otherwise have as a result of this Guaranty until such time as the
         Loans hereunder shall have been paid and the Commitments have been
         terminated. Each of the Guarantors hereby further agrees not to
         exercise any right to enforce any other remedy which the Administrative
         Agent and the Lenders now have or may hereafter have against any Other
         Party, any endorser or any other guarantor of all or any part of the
         indebtedness of the Borrowers and any benefit of, and any right to
         participate in, any security or collateral given to or for the benefit
         of the Lenders to secure payment of the indebtedness of the Borrowers
         until such time as the Loans hereunder shall have been paid and the
         Commitments have been terminated.

         10.8     LIMITATION ON ENFORCEMENT.

         The Lenders agree that this Guaranty may be enforced only by the action
of the Administrative Agent acting upon the instructions of the Majority Lenders
and that no Lender shall have any right individually to seek to enforce or to
enforce this Guaranty, it being understood and agreed that such rights and
remedies may be exercised by the Administrative Agent for the benefit of the
Lenders upon the terms of this Agreement. The Lenders further agree that this
Guaranty may not be enforced against any director, officer, employee or
stockholder of the Guarantors.

         10.9     CONFIRMATION OF PAYMENT.

         The Administrative Agent and the Lenders will, upon request after
payment of the indebtedness and obligations which are the subject of this
Guaranty and termination of the commitments relating thereto, confirm to the
Borrowers, the Guarantors or any other Person that such indebtedness and
obligations have been paid and the commitments relating thereto terminated,
subject to the provisions of Section 10.2.

                              EMPLOYMENT AGREEMENT


              THIS EMPLOYMENT AGREEMENT is made on August 7, 1998,1998
between Penton Media, Inc., a Delaware corporation (the "COMPANY"), and William
C. Donohue ("EXECUTIVE").

              This Employment Agreement is entered into as a condition precedent
to the consummation of the transactions contemplated in a Combination Agreement
dated as of May 21, 1998 by and among the Company, Executive and other parties
(the "COMBINATION AGREEMENT"). Pursuant to the Combination Agreement, Donohue
Meehan Publishing Company, an Illinois corporation, is being merged with and
into D-M Acquisition Corp., an Illinois corporation wholly-owned by the Company
that is changing its name to Donohue Meehan Publishing Company in connection
with the merger. The corporation surviving the merger as Donohue Meehan
Publishing Company is referred to herein as "D.M. PUB."; the original Donohue
Meehan Publishing Company is referred to herein as "D.M. PUB.'S PREDECESSOR".

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

              1. EMPLOYMENT. The Company shall employ Executive, and Executive
accepts employment with the Company, upon the terms and conditions set forth in
this Agreement, for the period beginning at the Effective Time (as defined in
the Combination Agreement) and ending on the second anniversary of the Effective
Time (the "EMPLOYMENT PERIOD").

               2. POSITION AND DUTIES.

              (a) During the Employment Period, Executive shall serve as the
President of D.M. Pub., and shall have the normal duties, responsibilities and
authority of an executive serving in such position, under the direction of the
Board of Directors of the Company (the "BOARD"), the Chief Executive Officer and
the Chief Operating Officer of the Company and the Board of Directors of D.M.
Pub.

              (b) Until the Company's 2000 annual meeting of stockholders,
Executive shall serve as a director of the Company.

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

              (d) During the Employment Period, Executive shall devote his full
business time and attention (except for permitted vacation periods, reasonable
periods of illness or other incapacity and, provided such activities do not
exceed those in which Executive has engaged in the past while serving as the
President of D.M. Pub.'s predecessor, participation in charitable and civic
endeavors and management of Executive's personal investments and business
interests) to the business and affairs of D.M. Pub.; provided that the Company
may require Executive to devote up to 10% of his





<PAGE>   2



business time to the business and affairs of the Company and its other
subsidiaries and affiliates. Executive shall perform his duties and
responsibilities to the best of his abilities in a diligent, trustworthy,
businesslike and efficient manner.

              (e) Executive shall be based at a location in, and shall perform
his duties and responsibilities principally in, the Chicago metropolitan area,
and shall not be required to travel outside that area significantly more
extensively than he has done in the past in the ordinary course of the business
of D.M. Pub.'s predecessor.

              (f) Nothing contained in this Paragraph 2 shall constitute a
waiver by either the Company or Executive of any of the provisions of Section
2.4 (g)(iv) of the Combination Agreement.

              3.     COMPENSATION AND BENEFITS.

              (a) SALARY. The Company agrees to pay Executive a salary during
the Employment Period, in semimonthly installments. Executive's salary shall be
$250,000 per annum.

              (b) BONUS. If, based on the final determinations of the Surviving
Corporation's Pre- Tax Profits for 1998 and 1999 pursuant to Section 2.4 of the
Combination Agreement, the total Contingent Cash Payments which the D-M
Shareholders, in the aggregate, would have become entitled to receive pursuant
to Section 2.4(g)(i) of the Combination Agreement would have exceeded $4.0
million had there been no $4.0 million limitation on the total amount of such
Contingent Cash Payments, the Company shall pay to Executive, on the date on
which the Employment Period is scheduled to end, an amount equal to (x) one-half
of such excess divided by (y) four and one-half. Notwithstanding the foregoing:
(i) the amount of the bonus shall not exceed $114,000 and (ii) if any event
described in clause (B) of the final sentence of Section 2.4(g)(i) of the
Combination Agreement occurs, the amount of the bonus shall be $114,000. (Thus,
for example, if the total amount of Contingent Cash Payments which the D-M
Shareholders, in the aggregate, become entitled to receive is less than $4.0
million, the amount of the bonus will be zero dollars, and if the total amount
of Contingent Cash Payments which the D-M Shareholders, in the aggregate, become
entitled to receive is $4.0 million but such total amount would have been $5.026
million but for the $4.0 million limitation, the amount of the bonus will be
$114,000). For purposes of this Agreement, any bonus will be deemed earned on
(but not until) the date on which the Employment Period is scheduled to end.

              (c) EXPENSE REIMBURSEMENT. The Company shall reimburse Executive
for all reasonable expenses incurred by him in the course of performing his
duties under this Agreement which are consistent with the Company's policies in
effect from time to time with respect to travel, entertainment and other
business expenses, subject to the Company's requirements applicable generally
with respect to reporting and documentation of such expenses.

              (d) STANDARD BENEFITS PACKAGE. In addition to the salary and any
bonus earned, Executive shall be entitled during the Employment Period to
participate in the Company's standard benefits package in effect from time to
time, on the same basis (including sharing of costs) as other



                                       2

<PAGE>   3



executives of the Company having principal responsibility for magazines
comparable in profit contribution to those for which Executive has principal
responsibility; provided that (i) any awards made to Executive under the Penton
1998 Stock Awards Plan (as defined in the Combination Agreement) prior to
January 1, 2000 (or, if earlier, the occurrence of any event described in clause
(B) of the final sentence of Section 2.4(g)(i) of the Combination Agreement)
shall be limited to non-qualified options and (ii) Executive shall be entitled
to vacation at the rate of four weeks per calendar year. In order to be provided
such employee benefits (other than vacation), Executive shall satisfy such
requirements for eligibility and coverage as may be in force from time to time
during the Employment Period taking into account the provisions of the second
sentence of Section 7.8(i) of the Combination Agreement.

              4.    TERMINATION.

              (a) Notwithstanding Paragraph 1 hereof, the Employment Period
shall end early upon the first to occur of any of the following events:

                    (i)    Executive's death;

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

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

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

                    (v)    Executive's termination of Executive's employment for
                           Good Reason, by means of written notice to the
                           Company identifying such termination as a Termination
                           by Executive for Good Reason ("TERMINATION BY
                           EXECUTIVE FOR GOOD REASON").

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

                    (i)    the commission by Executive of a felony;

                    (ii)   the commission by Executive of any act involving
                           fraud or dishonesty with respect to the Company or
                           any of its subsidiaries or affiliates which causes
                           harm or damage material to them as a whole;




                                       3

<PAGE>   4



                    (iii)  gross negligence or willful misconduct by Executive
                           related to his duties and responsibilities hereunder
                           which causes harm or damage material to the Company
                           and its subsidiaries and affiliates as a whole;

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

                    (v)    breach by Executive of any of the agreements in
                           Paragraph 7 hereof; or

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

              (c) For purposes of this Agreement, "GOOD REASON" shall mean any
breach by the Company of this Agreement which is material and which is not cured
within thirty (30) days after written notice thereof to the Company from
Executive.

              5.    POST-EMPLOYMENT PERIOD PAYMENTS.

              (a) If the Employment Period ends on the date on which it is
scheduled to end, or if the Employment Period ends early for any reason,
Executive shall thereafter be entitled to (and only to):

                    (i)    any salary or bonus which has been earned but is
                           unpaid, any reimbursable expenses which have been
                           incurred but are unpaid, and any vacation days which
                           have accrued but are unused and unexpired under the
                           Company's vacation policy, as of the end of the
                           Employment Period;

                    (ii)   any plan benefits which by their terms extend beyond
                           termination of Executive's employment;

                    (iii)  any benefits to which Executive is entitled under the
                           Consolidated Omnibus Budget Reconciliation Act of
                           1985, as amended ("COBRA"); and

                    (iv)   any other amount(s) payable pursuant to the
                           succeeding provisions of this Paragraph 5.

                    (b) In the event of Executive's death during the Employment
Period, the Company shall pay to Executive's estate (or such person or persons
as Executive may designate in a written instrument signed by him) amounts equal
to the amounts Executive would have received as salary and bonus had the
Employment Period remained in effect until the date on which it was scheduled to
end, at the times such amounts would have been paid.




                                       4

<PAGE>   5



                    (c) If the Employment Period ends early on account of
Termination for Cause: (i) the Company shall pay Executive an amount equal to
that Executive would have received as salary had the Employment Period remained
in effect until the later of the effective date of the Company's termination of
Executive's employment or the date thirty days after the Company's notice to
Executive of such termination; and (ii) the Company shall pay to Executive an
amount equal to any amount Executive would have received as bonus had the
Employment Period remained in effect until the date on which it was scheduled to
end, reduced to the fraction thereof of which the numerator is the number of
days during the Employment Period which have elapsed as of the end of the
Employment Period and the denominator is 731, at the time such amount would have
been paid.

                    (d) If the Employment Period ends early on account of a
Termination without Cause or a Termination by Executive for Good Reason, the
Company: (i) shall pay to Executive amounts equal to the amounts Executive would
have received as salary and bonus had the Employment Period remained in effect
until the date on which it was scheduled to end, at the times such amounts would
have been paid, less payments, if any, to which Executive is entitled during the
payment period under any disability benefit plan or the like in which Executive
has participated as an employee of the Company; and (ii) shall permit Executive
to participate, until the date on which the Employment Period was scheduled to
end, in any medical, dental and life insurance programs included in the
Company's standard benefits package in effect from time to time, on the same
basis (including sharing of costs) as other executives of the Company having
principal responsibility for magazines comparable in profit contribution to
those for which Executive had principal responsibility at the end of the
Employment Period, in the case of each of such programs to the extent
participation by a former employee is permitted by the terms thereof. It is
expressly understood that the Company's payment obligations under this (d) shall
cease in the event Executive breaches any of his agreements in Paragraph 6 or 7
hereof.

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



                                       5

or to the work product or the business of the Company or any of its subsidiaries
or affiliates, which he may then possess or have under his control.

                    7.     NON-COMPETE, NON-SOLICITATION.

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

                    (b) Executive agrees that during the Employment Period and
for a period of three years after termination of his employment with the Company
he shall not in any manner, directly or indirectly, through any person, firm or
corporation, alone or as a member of a partnership or as an officer, director,
stockholder, investor or employee of or in any other corporation or enterprise
or otherwise, engage or be engaged in, or assist any other person, firm,
corporation or enterprise in engaging or being engaged in, anywhere in the
world, the publishing or production of any Business Information Product (as
defined in the Combination Agreement) that competes with a Business Information
Product being published or produced by the Company or any of its subsidiaries or
affiliates when the Employment Period ends.

                    (c) Executive further agrees that during the Employment
Period and for three years thereafter he shall not in any manner, directly or
indirectly, induce or attempt to induce any employee of the Company or of any of
its subsidiaries or affiliates to quit or abandon his/her employ.

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

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

                    (f) The provisions of (b) of this Paragraph shall not apply
following a Termination without Cause or a Termination by Executive for Good
Reason.

                    8. ENFORCEMENT. Because Executive's services are unique and
because Executive has access to Confidential Information and work product, the
parties hereto agree that the Company would be damaged irreparably in the event
any of the provisions of Paragraph 6 or 7 hereof were not performed in
accordance with their specific terms or were otherwise breached and that money


                                       6

<PAGE>   7



damages would be an inadequate remedy for any such non-performance or breach.
Therefore, the Company or its permitted successors or assigns shall be entitled,
in addition to other rights and remedies existing in their favor, to an
injunction or injunctions to prevent any breach or threatened breach of any of
such provisions and to enforce such provisions specifically (without posting a
bond or other security).

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

                    10. SURVIVAL. Subject to any limits on applicability
contained therein, Paragraphs 6, 7 and 8 hereof shall survive and continue in
full force in accordance with their terms notwithstanding any termination of the
Employment Period.

                    11. NOTICES. Any notice provided for in this Agreement shall
be in writing and shall be either personally delivered, sent by reputable
overnight carrier or mailed by first class mail, return receipt requested, to

sent or mailed.

                    12. SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under

illegal or unenforceable in any respect under any applicable law

                                       7
<PAGE>   8


or rule in any jurisdiction, such invalidity, illegality or unenforceability
shall not affect any other provision or any other jurisdiction, but this
Agreement shall be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

                    13. COMPLETE AGREEMENT. This Agreement embodies the complete
agreement and understanding between the parties with respect to the subject
matter hereof and effective upon the commencement of the Employment Period
supersedes and preempts any prior understandings, agreements or representations

party. Executive hereby consents to the assignment by the Company of all of its
rights and obligations hereunder to: (i) any subsidiary or affiliate of the

Executive's duties under this Agreement relate are transferred thereto on or
after January 1, 2000 and (ii) any successor to the Company by merger or

in each case provided such transferee or successor assumes the liabilities of
the Company hereunder.

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

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

IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the date
first written above.

                              EMPLOYMENT AGREEMENT


              THIS EMPLOYMENT AGREEMENT is made on August 7, 1998 between Penton
Media, Inc., a Delaware corporation (the "COMPANY"), and John J. Meehan
("EXECUTIVE").

              This Employment Agreement is entered into as a condition precedent
to the consummation of the transactions contemplated in a Combination Agreement
dated as of May 21, 1998 by and among the Company, Executive and other parties
(the "COMBINATION AGREEMENT"). Pursuant to the Combination Agreement, Donohue
Meehan Publishing Company, an Illinois corporation, is being merged with and
into D-M Acquisition Corp., an Illinois corporation wholly-owned by the Company
that is changing its name to Donohue Meehan Publishing Company in connection
with the merger. The corporation surviving the merger as Donohue Meehan
Publishing Company is referred to herein as "D.M. PUB."; the original Donohue
Meehan Publishing Company is referred to herein as "D.M. PUB.'S PREDECESSOR".

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

              1. EMPLOYMENT. The Company shall employ Executive, and Executive
accepts employment with the Company, upon the terms and conditions set forth in
this Agreement, for the period beginning at the Effective Time (as defined in
the Combination Agreement) and ending on the second anniversary of the Effective
Time (the "EMPLOYMENT PERIOD").

                  2. POSITION AND DUTIES.

              (a) During the Employment Period, Executive shall serve as the
Executive Vice President of D.M. Pub., and shall have the normal duties,
responsibilities and authority of an executive serving in such position, under
the direction of the Board of Directors of the Company (the "BOARD"), the Chief
Executive Officer and the Chief Operating Officer of the Company and the Board
of Directors of D.M. Pub.

              (b) Until the Company's 2000 annual meeting of stockholders,
Executive shall serve as a director of the Company.

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

              (d) During the Employment Period, Executive shall devote his full
business time and attention (except for permitted vacation periods, reasonable
periods of illness or other incapacity and, provided such activities do not
exceed those in which Executive has engaged in the past while serving as the
Executive Vice President of D.M. Pub.'s predecessor, participation in charitable
and civic endeavors and management of Executive's personal investments and
business interests) to the business and affairs of D.M. Pub.; provided that the
Company may require Executive to devote up to 10% of his business time to the
business and affairs of the Company and its other subsidiaries and





<PAGE>   2



affiliates. Executive shall perform his duties and responsibilities to the
best of his abilities in a diligent, trustworthy, businesslike and efficient
manner.

              (e) Executive shall be based at a location in, and shall perform
his duties and responsibilities principally in, the Philadelphia metropolitan
area, and shall not be required to travel outside that area significantly more
extensively than he has done in the past in the ordinary course of the business
of D.M. Pub.'s predecessor.

              (f) Nothing contained in this Paragraph 2 shall constitute a
waiver by either the Company or Executive of any of the provisions of Section
2.4 (g)(iv) of the Combination Agreement.

              3.     COMPENSATION AND BENEFITS.

              (a) SALARY. The Company agrees to pay Executive a salary during
the Employment Period, in semimonthly installments. Executive's salary shall be
$250,000 per annum.

              (b) BONUS. If, based on the final determinations of the Surviving
Corporation's Pre- Tax Profits for 1998 and 1999 pursuant to Section 2.4 of the
Combination Agreement, the total Contingent Cash Payments which the D-M
Shareholders, in the aggregate, would have become entitled to receive pursuant
to Section 2.4(g)(i) of the Combination Agreement would have exceeded $4.0
million had there been no $4.0 million limitation on the total amount of such
Contingent Cash Payments, the Company shall pay to Executive, on the date on
which the Employment Period is scheduled to end, an amount equal to (x) one-half
of such excess divided by (y) four and one-half. Notwithstanding the foregoing:
(i) the amount of the bonus shall not exceed $114,000 and (ii) if any event
described in clause (B) of the final sentence of Section 2.4(g)(i) of the
Combination Agreement occurs, the amount of the bonus shall be $114,000. (Thus,
for example, if the total amount of Contingent Cash Payments which the D-M
Shareholders, in the aggregate, become entitled to receive is less than $4.0
million, the amount of the bonus will be zero dollars, and if the total amount
of Contingent Cash Payments which the D-M Shareholders, in the aggregate, become
entitled to receive is $4.0 million but such total amount would have been $5.026
million but for the $4.0 million limitation, the amount of the bonus will be
$114,000). For purposes of this Agreement, any bonus will be deemed earned on
(but not until) the date on which the Employment Period is scheduled to end.

              (c) EXPENSE REIMBURSEMENT. The Company shall reimburse Executive
for all reasonable expenses incurred by him in the course of performing his
duties under this Agreement which are consistent with the Company's policies in
effect from time to time with respect to travel, entertainment and other
business expenses, subject to the Company's requirements applicable generally
with respect to reporting and documentation of such expenses.

              (d) STANDARD BENEFITS PACKAGE. In addition to the salary and any
bonus earned, Executive shall be entitled during the Employment Period to
participate in the Company's standard benefits package in effect from time to
time, on the same basis (including sharing of costs) as other executives of the
Company having principal responsibility for magazines comparable in profit




                                       2
<PAGE>   3



contribution to those for which Executive has principal responsibility; provided
that (i) any awards made to Executive under the Penton 1998 Stock Awards Plan
(as defined in the Combination Agreement) prior to January 1, 2000 (or, if
earlier, the occurrence of any event described in clause (B) of the final
sentence of Section 2.4(g)(i) of the Combination Agreement) shall be limited to
non-qualified options and (ii) Executive shall be entitled to vacation at the
rate of four weeks per calendar year. In order to be provided such employee
benefits (other than vacation), Executive shall satisfy such requirements for
eligibility and coverage as may be in force from time to time during the
Employment Period taking into account the provisions of the second sentence of
Section 7.8(i) of the Combination Agreement.

              4.    TERMINATION.

              (a) Notwithstanding Paragraph 1 hereof, the Employment Period
shall end early upon the first to occur of any of the following events:

                    (i)    Executive's death;

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

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

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

                    (v)    Executive's termination of Executive's employment for
                           Good Reason, by means of written notice to the
                           Company identifying such termination as a Termination
                           by Executive for Good Reason ("TERMINATION BY
                           EXECUTIVE FOR GOOD REASON").

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

                    (i)    the commission by Executive of a felony;

                    (ii)   the commission by Executive of any act involving
                           fraud or dishonesty with respect to the Company or
                           any of its subsidiaries or affiliates which causes
                           harm or damage material to them as a whole;





                                       3
<PAGE>   4



                    (iii)  gross negligence or willful misconduct by Executive
                           related to his duties and responsibilities hereunder
                           which causes harm or damage material to the Company
                           and its subsidiaries and affiliates as a whole;

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

                    (v)     breach by Executive of any of the agreements in
                            Paragraph 7 hereof; or

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

              (c) For purposes of this Agreement, "GOOD REASON" shall mean any
breach by the Company of this Agreement which is material and which is not cured
within thirty (30) days after written notice thereof to the Company from
Executive.

              5.    POST-EMPLOYMENT PERIOD PAYMENTS.

              (a) If the Employment Period ends on the date on which it is
scheduled to end, or if the Employment Period ends early for any reason,
Executive shall thereafter be entitled to (and only to):

                    (i)    any salary or bonus which has been earned but is
                           unpaid, any reimbursable expenses which have been
                           incurred but are unpaid, and any vacation days which
                           have accrued but are unused and unexpired under the
                           Company's vacation policy, as of the end of the
                           Employment Period;

                    (ii)   any plan benefits which by their terms extend beyond
                           termination of Executive's employment;

                    (iii)  any benefits to which Executive is entitled under the
                           Consolidated Omnibus Budget Reconciliation Act of
                           1985, as amended ("COBRA"); and

                    (iv)   any other amount(s) payable pursuant to the
                           succeeding provisions of this Paragraph 5.

                    (b) In the event of Executive's death during the Employment
Period, the Company shall pay to Executive's estate (or such person or persons
as Executive may designate in a written instrument signed by him) amounts equal
to the amounts Executive would have received as salary and bonus had the
Employment Period remained in effect until the date on which it was scheduled to
end, at the times such amounts would have been paid.

<PAGE>   5



                    (c) If the Employment Period ends early on account of
Termination for Cause: (i) the Company shall pay Executive an amount equal to
that Executive would have received as salary had the Employment Period remained
in effect until the later of the effective date of the Company's termination of
Executive's employment or the date thirty days after the Company's notice to
Executive of such termination; and (ii) the Company shall pay to Executive an
amount equal to any amount Executive would have received as bonus had the
Employment Period remained in effect until the date on which it was scheduled to
end, reduced to the fraction thereof of which the numerator is the number of
days during the Employment Period which have elapsed as of the end of the
Employment Period and the denominator is 731, at the time such amount would have
been paid.

                    (d) If the Employment Period ends early on account of a
Termination without Cause or a Termination by Executive for Good Reason, the
Company: (i) shall pay to Executive amounts equal to the amounts Executive would
have received as salary and bonus had the Employment Period remained in effect
until the date on which it was scheduled to end, at the times such amounts would
have been paid, less payments, if any, to which Executive is entitled during the
payment period under any disability benefit plan or the like in which Executive
has participated as an employee of the Company; and (ii) shall permit Executive
to participate, until the date on which the Employment Period was scheduled to
end, in any medical, dental and life insurance programs included in the
Company's standard benefits package in effect from time to time, on the same
basis (including sharing of costs) as other executives of the Company having
principal responsibility for magazines comparable in profit contribution to
those for which Executive had principal responsibility at the end of the
Employment Period, in the case of each of such programs to the extent
participation by a former employee is permitted by the terms thereof. It is
expressly understood that the Company's payment obligations under this (d) shall
cease in the event Executive breaches any of his agreements in Paragraph 6 or 7
hereof.

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


                                       5

or to the work product or the business of the Company or any of its subsidiaries
or affiliates, which he may then possess or have under his control.

                    7.     NON-COMPETE, NON-SOLICITATION.

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

                    (b) Executive agrees that during the Employment Period and
for a period of three years after termination of his employment with the Company
he shall not in any manner, directly or indirectly, through any person, firm or
corporation, alone or as a member of a partnership or as an officer, director,
stockholder, investor or employee of or in any other corporation or enterprise
or otherwise, engage or be engaged in, or assist any other person, firm,
corporation or enterprise in engaging or being engaged in, anywhere in the
world, the publishing or production of any Business Information Product (as
defined in the Combination Agreement) that competes with a Business Information
Product being published or produced by the Company or any of its subsidiaries or
affiliates when the Employment Period ends.

                    (c) Executive further agrees that during the Employment
Period and for three years thereafter he shall not in any manner, directly or
indirectly, induce or attempt to induce any employee of the Company or of any of
its subsidiaries or affiliates to quit or abandon his/her employ.

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

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

                    (f) The provisions of (b) of this Paragraph shall not apply
following a Termination without Cause or a Termination by Executive for Good
Reason.

                    8. ENFORCEMENT. Because Executive's services are unique and
because Executive has access to Confidential Information and work product, the
parties hereto agree that the Company would be damaged irreparably in the event
any of the provisions of Paragraph 6 or 7 hereof were not performed in
accordance with their specific terms or were otherwise breached and that money

                                       6

<PAGE>   7



damages would be an inadequate remedy for any such non-performance or breach.
Therefore, the Company or its permitted successors or assigns shall be entitled,
in addition to other rights and remedies existing in their favor, to an
injunction or injunctions to prevent any breach or threatened breach of any of
such provisions and to enforce such provisions specifically (without posting a
bond or other security).

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

                    10. SURVIVAL. Subject to any limits on applicability
contained therein, Paragraphs 6, 7 and 8 hereof shall survive and continue in
full force in accordance with their terms notwithstanding any termination of the
Employment Period.

                    11. NOTICES. Any notice provided for in this Agreement shall
be in writing and shall be either personally delivered, sent by reputable
overnight carrier or mailed by first class mail, return receipt requested, to

                    12. SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under

illegal or unenforceable in any respect under any applicable law



                                       7

or rule in any jurisdiction, such invalidity, illegality or unenforceability
shall not affect any other provision or any other jurisdiction, but this
Agreement shall be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

Executive's duties under this Agreement relate are transferred thereto on or
after January 1, 2000 and (ii) any successor to the Company by merger or
consolidation or purchase of all or substantially all of the Company's assets;
in each case provided such transferee or successor assumes the liabilities of
the Company hereunder.

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

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

IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the date
first written above.

                              EMPLOYMENT AGREEMENT


                  This EMPLOYMENT AGREEMENT ("AGREEMENT") made as of July 16,

                                   WITNESSETH:

                  WHEREAS, Executive desires to become an executive employee of
the Company, and the Company desires to employ Executive as an executive
employee;

                  WHEREAS, pursuant to a Combination Agreement among the Company
and other parties, all of the outstanding capital stock of the Company will be
distributed by Pittway Corporation to the shareholders of Pittway Corporation
(the "SPINOFF");

                  WHEREAS, as a result of the Spinoff, the Company will become
publicly held;

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

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

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

                  1. EMPLOYMENT. The Company shall employ Executive, and
Executive accepts employment with the Company, upon the terms and conditions set
forth in this Agreement for the period beginning on the Effective Date (as
defined in paragraph 20) and ending as provided in paragraph 5 hereof (the
"EMPLOYMENT PERIOD").

                  2.       POSITION AND DUTIES.

                  (a) During the Employment Period, Executive shall serve as the
Group President of the Company's New York Division (the "DIVISION"), with
initial responsibility for the Company's electronics group and independent
exhibitions and shall have the normal duties, responsibilities and authority of
an executive serving in such position with such responsibilities, subject to the
power of the Board of Directors of the Company (the "BOARD") or the Chief
Executive Officer of the Company to reasonably expand or limit such duties,
responsibilities and authority, either generally or in specific instances.
Executive also shall have the title Executive Vice President of the Company.

                  (b) Executive shall report to the Chief Executive Officer or

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

                  (d) Executive shall have offices at the Company's Hasbrouck
Heights and New York City offices, and shall perform his duties and
responsibilities principally from those locations. In the event the Company and
the Executive agree at any time that the Executive should relocate to the

executive relocation.

                  3.       COMPENSATION AND BENEFITS.

                  (a) SALARY. The Company agrees to pay Executive a salary

discretion, increase it.

                  (b)      BONUS(ES).

                  (i)      SIGNING BONUS. In order to mitigate any loss
                           Executive would incur relative to Executive's United
                           News & Media options as a result of the execution of
                           this Agreement, Executive shall receive a signing
                           bonus of $200,000 payable, at the Executive's
                           election, in either (A) cash (less applicable
                           withholding taxes) upon the Effective Date, (B) such
                           number of shares of the Company's Common Stock as is
                           determined by dividing $200,000 by the average
                           closing price per share of the Company's Common Stock
                           on the New York Stock Exchange for the five trading
                           days preceding the Effective Date, to be delivered to
                           Executive on the first anniversary of the Effective
                           Date, or (C) any combination thereof, provided that
                           Executive shall make appropriate tax withholding
                           arrangements if he elects payment in shares of the
                           Company's Common Stock pursuant to the foregoing (B)
                           or (C).

                  (ii)     ANNUAL BONUS. Subject to approval by the Compensation
                           Committee of the Board (or if there is no such
                           Committee, the Board), beginning in the 1998 calendar
                           year, Executive shall be eligible for an annual bonus
                           based on the achievement of specified Division and
                           Company goals. The Division goal shall be based on
                           the Division's budgeted 1998 contribution profit of
                           $16,307,000. "Contribution profit" shall mean an
                           amount equal to the direct revenues of the New York
                           Division less direct operating expenses before any
                           allocation of corporate overheads as calculated by
                           the Company. The Company goal shall be based on the
                           Company's adjusted budgeted 1998

                           amortization ("EBITDA"), adjusted to take into
                           account the Spinoff, the related acquisition of the
                           operations of Donohue-Meehan Publishing Company for

                           the exclusion of the operations of Curtin &
                           Pease/Peneco, Inc. ("Adjusted Budgeted 1998 EBITDA").
                           The Company's Adjusted Budgeted 1998 EBITDA is
                           expected to be determined on or before July 31, 1998,
                           and shall be used for purposes of determining 1998
                           annual incentive compensation of the Executive and
                           other comparable executive officers of the Company.
                           The total bonus opportunity for 1998 at budget as
                           adjusted is $150,000, which amount shall be
                           guaranteed for 1998 regardless of Division or Company
                           performance. Executive shall receive additional
                           annual bonus for 1998 as follows: two percent of all
                           dollar amounts of the Division's contribution profit
                           in excess of the target specified above; and one
                           percent of all dollar amounts of the Company's EBITDA
                           in excess of Adjusted Budgeted 1998 EBITDA. Annual
                           bonus opportunities for subsequent years shall be
                           based on principles similar to the foregoing and
                           shall be comparable to bonus opportunities for
                           similarly situated Executives of the Company, but
                           with a minimum bonus opportunity of $200,000 per
                           year.

                  (c)      LONG TERM INCENTIVE.

                           Subject to approval by the Compensation Committee of
                           the Board (or, if there is no such Committee, the
                           Board), Executive will be granted an award entitling
                           him to earn additional long-term incentive
                           compensation over the 1998, 1999 and 2000 calendar
                           years up to $450,000 (the "PERFORMANCE AWARD"). Such
                           Performance Award shall become 100% vested on
                           December 31, 2000, if Executive remains an employee
                           of the Company until that date and

                           (A)      the Division's cumulative contribution
                                    profit for 1998, 1999 and 2000 attributable
                                    solely to Organic Growth (as hereinafter
                                    defined), equals or exceeds $56,627,000; or

                           (B)      the Division, through a combination of
                                    Organic Growth and Acquisition Growth (as
                                    hereinafter defined), achieves $30,000,000

                           before December 31, 2000, based on the following
                           schedule, if the following performance targets have
                           been met or exceeded by the Division:

                           (X)      if the Executive's employment is terminated
                                    in the circumstances described in this
                                    sentence during 1999 and the Division's 1998
                                    contribution profit equaled or exceeded
                                    $16,307,000, Executive shall be vested upon

                           Executive shall be 100% vested in such Performance
                           Award upon such termination of employment.

                           Any Performance Award that becomes payable shall be
                           paid to the Executive, at the Executive's election,
                           as soon as reasonably practicable after the Executive

                           Black- Scholes methodology applied on a basis
                           consistent with the application of such methodology
                           in connection with option grants to the other

                           executive officers of the Company) of $100,000, but

                           the fair market value of the Company's Common Stock
                           at the date of grant, such a number of shares of the
                           Company's Common Stock as is necessary to generate an
                           expected value per annual grant (using Black-Scholes
                           methodology applied on a basis consistent with the
                           application of such methodology in connection with
                           option grants to the other executive officers of the
                           Company) of $100,000, but in any event, for each

                           such year.

                  (iv)     If for any year subsequent to 1999, the Compensation
                           Committee of the Board (or, if there is no such
                           Committee, the Board) elects to grant Executive
                           options to purchase the Company's Common Stock with
                           an expected value less than $100,000, or if the
                           Compensation Committee of the Board (or, if there is
                           no such Committee, the Board) elects not to grant

                  (v)      The terms of each stock option (such as length and
                           exercisability) shall be as set forth in a stock
                           option agreement between the Company and the

                           each such option that is otherwise exercisable in
                           accordance with its terms may be exercised by the
                           Executive for the one- year period following any
                           termination of the Executive's employment by the
                           Company not for Cause or by the Executive for Good
                           Reason.

                  (vi)     If, at the time of the grant of any option pursuant
                           to this paragraph (d), the issuance of shares upon

Agreement, it is expressly understood and agreed that if there is a significant
reduction in the level of the business to which Executive's duties under this
Agreement relate, or if all or any significant part of such business is disposed
of by the Company and/or its subsidiaries or affiliates during the Employment

Compensation Committee of the Board (or, if there is no such Committee, the
Board) may make adjustments in Executive's duties, responsibility and authority,

                  (a) If the Employment Period ends on the date on which
(without any extension thereof) it is then scheduled to end pursuant to
paragraph 5 hereof, or if the Employment Period ends early pursuant to paragraph
5 hereof for any reason, Executive shall cease to have any rights to salary,
bonus (if any), options, expense reimbursements or other benefits other than:

Executive's employment or the date thirty days after the Company's notice to
Executive of such termination. The Company shall make no further payments to
Executive except as contemplated in (a)(i), (ii) and (iii) above.

Company shall pay to Executive amounts equal to the amounts Executive would have
received as salary (based on Executive's salary then in effect or, if greater,
Executive's Reference Salary) had the Employment Period remained in effect for a
period of twenty-four (24) months after the last day of the month in which the
Employment Period ends, at the times such amounts would have been paid (in the
event Executive is entitled during the payment period to any payments under any
disability benefit plan or the like in which Executive has participated as an
employee of the Company, less such payments), plus, for the year in which such
termination occurs and the following year, the amount the Executive would have
received as an annual bonus if the Division and the Company performed at bonus
target for the year in which such termination occurs, such amount payable first
at the time the annual bonus normally would be paid for the year in which such
termination occurs and again at the time the annual bonus normally would be paid
for the following year; PROVIDED, HOWEVER, that in the event of Executive's
death during the payment period, the Company shall pay any subsequent such
amounts to Executive's estate (or such person or persons as Executive may
designate in a written instrument signed by him and delivered to the Company
prior to his death) or, if so elected by the payee(s) by written notice to the
Company within the period of sixty (60) days after the date of Executive's
death, shall pay to such payee(s) a lump sum amount equivalent to the discounted
present value of such amounts, discounted at the publicly announced reference
rate for commercial lending of the Company's principal lending bank in effect at
the date of notice to the Company of such election, with said amount to be paid
on a date no later than thirty (30) days following the date of notice to the
Company of such election. In addition, the Company shall reimburse Executive
(net after taxes on the receipt of such reimbursement) for any premiums paid by
Executive for health insurance provided to Executive (for Executive and his
dependents) by the Company subsequent to the end of the Employment Period
pursuant to the requirements of COBRA as in effect on the date of this
Agreement. The Company shall make no further payments to Executive except as
contemplated in (a)(i), (ii) and (iii) above. It is expressly understood that
the Company's payment obligations under this (d) shall cease in the event
Executive breaches any of his agreements in paragraph 7 or 8 hereof.

                  (e) If the Employment Period ends early pursuant to paragraph
5 hereof on account of a Termination by Executive with Advance Notice, the
Company shall make no further payments to Executive except as contemplated in
(a)(i), (ii) and (iii) above.

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

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

disclosure is (i) made in the ordinary course of Executive's performance of his
duties under

this Agreement or (ii) required by any subpoena or other legal process (in which
event Executive will give the Company prompt notice of such subpoena or other
legal process in order to permit the Company to seek appropriate protective
orders), and that he shall not use any Confidential Information for his own
account without the prior written consent of the Chief Executive Officer of the
Company. Executive shall deliver to the Company at the termination of the
Employment Period, or at any other time the Company may reasonably request, all
memoranda, notes, plans, records, reports, computer tapes and software and other
documents and data (and copies thereof) relating to the Confidential
Information, or to the work product or the business of the Company or any of its
subsidiaries or affiliates which he may then possess or have under his control.

                  8.       NON-COMPETE, NON-SOLICITATION.

                  (a) Executive acknowledges that in the course of his
employment with the Company pursuant to this Agreement he will become familiar,
and during the course of his employment by the Company or any of its

other confidential information concerning the Company and its subsidiaries and
affiliates and predecessors thereof and that his services have been and will be
of special, unique and extraordinary value to the Company.

                  (b) Executive agrees that during the Employment Period and for
any period following the Employment Period during which the Executive continues
to receive payments pursuant to this Agreement, he shall not in any manner,
directly or indirectly, through any person, firm or corporation, alone or as a
member of a partnership or as an officer, director, stockholder, investor or
employee of or in any other corporation or enterprise or otherwise, engage in or
be engaged in, or assist any other person, firm, corporation or enterprise in
engaging or being engaged in, any business then actively being conducted by the
Company or any of its subsidiaries or affiliates, including, without limitation,
the publication or production of any magazine, special issue, catalogue,
directory, newsletter, card deck, electronic/internet product, trade show,
exhibition or ancillary product. Notwithstanding the foregoing, the restrictions
of this subparagraph 8(b) shall not apply if Executive's employment with the
Company is terminated by the Executive for Good Reason during the two year
period following a Change of Control.

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

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

                  (e) If, at the time of enforcement of this paragraph, a court
holds that the restrictions stated herein are unreasonable under circumstances
then existing, the parties hereto agree that the maximum period, scope or
geographical area reasonable under such circumstances shall be

                                     - 13 -

<PAGE>   14



substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum period,
scope and area permitted by law.

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

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

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

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

attorneys' fees) reasonably incurred by Executive in obtaining such judgment and
shall pay Executive interest on the amount of each such cost or expense from the
date of payment thereof by Executive to the date of reimbursement by the Company
at a floating rate per annum equal to the publicly announced reference rate for
commercial lending of the Company's principal lending bank in effect from time

under the terms of the agreement referred to in paragraph 10, unless Miller
Freeman, Inc. agrees otherwise, Executive must give Miller Freeman, Inc. ninety
days' notice in order to terminate his employment thereunder. Executive agrees
to give Miller Freeman, Inc. such notice within seven days of the date hereof.
Such notice shall request that Miller Freeman, Inc. waive the requirement of the
ninety day notice period. Executive shall deliver a copy of such notice to the
Company. In the event Executive shall not have provided the Company with the
copy of such notice within seven days of the date hereof, the Company may, at
its option, declare this Agreement null and void. The Executive shall use his
best efforts to obtain the written agreement of Miller Freeman, Inc. to the
termination of his employment under such agreement at the earliest possible date
after the Executive gives such notice. Executive's employment hereunder shall
commence on the first day after the date on which Miller Freeman, Inc. agrees to
the termination of Executive's employment with Miller Freeman, Inc., or, if
Miller Freeman, Inc. does not so agree, on the first day after the expiration of
the ninety day notice period (the first day of Executive's employment hereunder
being referred to herein as the "EFFECTIVE DATE").

         4. OPTION RIGHTS. The Board may, from time to time and upon such terms

contained in the following provisions:

                  (a) Each grant shall specify the number of shares of Common
Stock to which it pertains subject to the limitations set forth in Section 3 of
this plan.

                  (b) Each grant shall specify an Option Price per share. The
Option Price of an Incentive Stock Option may not be less than 100% of the
Market Value per Share on the Date of Grant as set by the Board on such date.
The Option Price of all other Option Rights may not be less than 85% of the
Market Value per Share on the Date of Grant as set by the Board on such date and
may not be less than the par value of a share of Common Stock.

                  (c) Each grant shall specify whether the Option Price shall be
payable (i) in cash or by check acceptable to the Company, (ii) by the actual or
constructive transfer to the Company of shares of Common Stock owned by the
Optionee for at least 6 months (or other consideration authorized pursuant to
Section 4(d)) having a value at the time of exercise equal to the total Option
Price, or (iii) by a combination of such methods of payment.

                  (d) The Board may determine, at or after the Date of Grant,
that payment of the Option Price of any Option Right (other than an Incentive
Stock Option) may also be made in whole or in part in the form of Restricted
Shares or other shares of Common Stock that are forfeitable or subject to
restrictions on transfer, Deferred Shares, Performance Shares (based, in each
case, on the Market Value per Share on the date of exercise), other Option
Rights (based on the Spread on the date of exercise) or Performance Units.
Unless otherwise determined by the Board at or after the Date of Grant, whenever
any Option Price is paid in whole or in part by means of any of the forms of
consideration specified in this Section 4(d), the shares of Common Stock
received upon the exercise of the Option Rights shall be subject to such risks
of forfeiture or restrictions on transfer as may correspond to any that apply to
the consideration surrendered, but only to the extent, determined with respect
to the consideration surrendered, of (i) the number of shares or Performance
Shares, (ii) the Spread of any unexercisable portion of Option Rights, or (iii)
the stated value of Performance Units.

                  (e) Any grant may provide for deferred payment of the Option
Price from the proceeds of sale through a broker on a date satisfactory to the
Company of some or all of the shares to which such exercise relates.

                  (f) Any grant may provide for payment of the Option Price, at
the election of the Optionee, in installments, with or without interest, upon
terms determined by the Board.

                  (g) Any grant may, at or after the Date of Grant, provide for
the automatic grant of Reload Option Rights to an Optionee upon the exercise of
Option Rights (including Reload Option Rights) using shares of Common Stock or
other consideration specified in Section 4(d). Reload Option Rights shall cover
up to the number of shares of Common Stock, Deferred Shares, Option Rights or
Performance Shares (or the number of shares of Common Stock having a value equal
to the value of any Performance Units) surrendered to the Company upon any such
exercise in payment of the Option Price or to meet any withholding obligations.
Reload Options may have an Option Price that is no less than that which
represents the same percentage of the Market Value per Share at the time of
exercise of the Option Rights that the share Option Price represented of the
Market Value per Share at the time the Option Rights being exercised were
granted and shall be on such other terms as may be specified by the Directors,
which may be the same as or different from those of the original Option Rights.

                  (h) Successive grants may be made to the same Participant
whether or not any Option Rights previously granted to such Participant remain
unexercised.

                  (i) Each grant shall specify the period or periods of
continuous service by the Optionee with the Company or any Subsidiary that is
necessary before the Option Rights or installments thereof will become
exercisable and may provide for the earlier exercise of such Option Rights in
the event of a Change of Control.

                  (j) Any grant of Option Rights may specify Management
Objectives that must be achieved as a condition to the exercise of such rights.

                  (k) Option Rights granted under this Plan may be (i) options,
including, without limitation, Incentive Stock Options, that are intended to
qualify under particular provisions of the Code, (ii) options that are not
intended so to qualify, or (iii) combinations of the foregoing.

                  (l) The Board may, at or after the Date of Grant of any Option
Rights (other than Incentive Stock Options), provide for the payment of dividend
equivalents to the Optionee on either a current or deferred or contingent basis
or may provide that such equivalents shall be credited against the Option Price.

                  (m) The exercise of an Option Right shall result in the
cancellation on a share-for-share basis of any Tandem Appreciation Right
authorized under Section 5 of this Plan.

                  (n) No Option Right shall be exercisable more than 10 years
from the Date of Grant.

                  (o) Each grant of Option Rights shall be evidenced by an
agreement executed on behalf of the Company by an officer and delivered to the
Optionee and containing such terms and provisions, consistent with this Plan, as
the Board may approve.

         5. APPRECIATION RIGHTS. (a) The Board may authorize the granting (i) to
any Optionee, of Tandem Appreciation Rights in respect of Option Rights granted
hereunder, and (ii) to any Participant, of Free-Standing Appreciation Rights. A
Tandem Appreciation Right shall be a right of the Optionee, exercisable by
surrender of the related Option Right, to receive from the Company an amount
determined by the Board, which shall be expressed as a percentage of the Spread
(not exceeding 100 percent) at the time of exercise. Tandem Appreciation Rights
may be granted at any time prior to the exercise or termination of the related
Option Rights; provided, however, that a Tandem Appreciation Right awarded in
relation to an Incentive Stock Option must be granted concurrently with such
Incentive Stock Option. A Free-Standing Appreciation Right shall be a right of
the Participant to receive from the Company an amount determined by the Board,
which shall be expressed as a percentage of the Spread (not exceeding 100
percent) at the time of exercise.

                  (b) Each grant of Appreciation Rights may utilize any or all
of the authorizations, and shall be subject to all of the requirements,
contained in the following provisions:

                           (i) Any grant may specify that the amount payable on
         exercise of an Appreciation Right may be paid by the Company in cash,
         in shares of Common Stock or in any combination thereof and may either
         grant to the Participant or retain in the Board the right to elect
         among those alternatives.

                           (ii) Any grant may specify that the amount payable on
         exercise of an Appreciation Right may not exceed a maximum specified by
         the Board at the Date of Grant.

                           (iii) Any grant may specify waiting periods before
         exercise and permissible exercise dates or periods.

                           (iv) Any grant may specify that such Appreciation
         Right may be exercised only in the event of, or earlier in the event
         of, a Change of Control.

                           (v) Any grant may provide for the payment to the
         Participant of dividend equivalents thereon in cash or shares of Common
         Stock on a current, deferred or contingent basis.

                           (vi) Any grant of Appreciation Rights may specify
         Management Objectives that must be achieved as a condition of the
         exercise of such Rights.

                           (vii) Each grant of Appreciation Rights shall be
         evidenced by an agreement executed on behalf of the Company by an
         officer and delivered to and accepted by the Participant, which
         agreement shall describe such Appreciation Rights, identify the related
         Option Rights (if applicable), state that such Appreciation Rights are
         subject to all the terms and conditions of this Plan, and contain such
         other terms and provisions, consistent with this Plan, as the Board may
         approve.



                                        7

<PAGE>   8



                  (c) Any grant of Tandem Appreciation Rights shall provide that
such Rights may be exercised only at a time when the related Option Right is
also exercisable and at a time when the Spread is positive, and by surrender of
the related Option Right for cancellation.

                  (d)      Regarding Free-standing Appreciation Rights only:

                           (i) Each grant shall specify in respect of each
                  Free-standing Appreciation Right a Base Price, which shall be
                  equal to or greater or less than the Market Value per Share on
                  the Date of Grant;

                           (ii) Successive grants may be made to the same
                  Participant regardless of whether any Free-standing
                  Appreciation Rights previously granted to the Participant
                  remain unexercised; and

                           (iii) No Free-standing Appreciation Right granted
                  under this Plan may be exercised more than 10 years from the
                  Date of Grant.


         6. RESTRICTED SHARES. The Board may also authorize the grant or sale of
Restricted Shares to Participants. Each such grant or sale may utilize any or
all of the authorizations, and shall be subject to all of the requirements,
contained in the following provisions:

                  (a) Each such grant or sale shall constitute an immediate
transfer of the ownership of shares of Common Stock to the Participant in
consideration of the performance of services, entitling such Participant to
voting, dividend and other ownership rights, but subject to the substantial risk
of forfeiture and restrictions on transfer hereinafter referred to.

                  (b) Each such grant or sale may be made without additional
consideration or in consideration of a payment by such Participant that is less
than Market Value per Share at the Date of Grant.

                  (c) Each such grant or sale shall provide that the Restricted
Shares covered by such grant or sale shall be subject to a "substantial risk of
forfeiture" within the meaning of Section 83 of the Code for a period to be
determined by the Board at the Date of Grant and may provide for the lapse of
such substantial risk of forfeiture in the event of a Change in Control.

                  (d) Each such grant or sale shall provide that during the
period for which such substantial risk of forfeiture is to continue, the
transferability of the Restricted Shares shall be prohibited or restricted in
the manner and to the extent prescribed by the Board at the Date of Grant (which
restrictions may include, without limitation, rights of repurchase or first
refusal in the Company or provisions subjecting the Restricted Shares to a
continuing substantial risk of forfeiture in the hands of any transferee).

                  (e) Any grant of Restricted Shares may specify Management
Objectives that, if achieved, will result in termination or early termination of
the restrictions applicable to such



                                        8

<PAGE>   9



shares. Each grant may specify in respect of such Management Objectives a
minimum acceptable level of achievement and may set forth a formula for
determining the number of Restricted Shares on which restrictions will terminate
if performance is at or above the minimum level, but falls short of full
achievement of the specified Management Objectives.

                  (f) Any such grant or sale of Restricted Shares may require
that any or all dividends or other distributions paid thereon during the period
of such restrictions be automatically deferred and reinvested in additional
Restricted Shares, which may be subject to the same restrictions as the
underlying award.

                  (g) Each grant or sale of Restricted Shares shall be evidenced
by an agreement executed on behalf of the Company by any officer and delivered
to and accepted by the Participant and shall contain such terms and provisions,
consistent with this Plan, as the Board may approve. Unless otherwise directed
by the Board, all certificates representing Restricted Shares shall be held in
custody by the Company until all restrictions thereon shall have lapsed,
together with a stock power or powers executed by the Participant in whose name
such certificates are registered, endorsed in blank and covering such Shares.


         7. DEFERRED SHARES. The Board may also authorize the granting or sale
of Deferred Shares to Participants. Each such grant or sale may utilize any or
all of the authorizations, and shall be subject to all of the requirements,
contained in the following provisions:

                  (a) Each such grant or sale shall constitute the agreement by
the Company to deliver shares of Common Stock to the Participant in the future
in consideration of the performance of services, but subject to the fulfillment
of such conditions during the Deferral Period as the Board may specify.

                  (b) Each such grant or sale may be made without additional
consideration or in consideration of a payment by such Participant that is less
than the Market Value per Share at the Date of Grant.

                  (c) Each such grant or sale shall be subject to a Deferral
Period, as determined by the Board at the Date of Grant, and may provide for the
lapse or other modification of such Deferral Period in the event of a Change in
Control.

                  (d) During the Deferral Period, the Participant shall have no
right to transfer any rights under his or her award and shall have no rights of
ownership in the Deferred Shares and shall have no right to vote them, but the
Board may, at or after the Date of Grant, authorize the payment of dividend
equivalents on such Shares on either a current or deferred or contingent basis,
either in cash or in additional shares of Common Stock.

                  (e) Each grant or sale of Deferred Shares shall be evidenced
by an agreement executed on behalf of the Company by any officer and delivered
to and accepted by the



                                        9

<PAGE>   10



Participant and shall contain such terms and provisions, consistent with this
Plan, as the Board may approve.


         8. PERFORMANCE SHARES AND PERFORMANCE UNITS. The Board may also
authorize the granting of Performance Shares and Performance Units that will
become payable to a Participant upon achievement of specified Management
Objectives. Each such grant may utilize any or all of the authorizations, and
shall be subject to all of the requirements, contained in the following
provisions:

                  (a) Each grant shall specify the number of Performance Shares
or Performance Units to which it pertains, which number may be subject to
adjustment to reflect changes in compensation or other factors; provided,
however, that no such adjustment shall be made in the case of a Covered Employee
where such action would result in the loss of the otherwise available exemption
of the award under Section 162(m) of the Code.

                  (b) The Performance Period with respect to each Performance
Share or Performance Unit shall be such period of time (not less than 3 years,
except in the event of a Change of Control, if the Board shall so determine;
provided, however, that no such acceleration determination shall be made in the
case of a Covered Employee where such action would result in the loss of the
otherwise available exemption of the award under Section 162(m) of the Code)
commencing with the Date of Grant (as shall be determined by the Board at the
time of grant).

                  (c) Any grant of Performance Shares or Performance Units shall
specify Management Objectives which, if achieved, will result in payment or
early payment of the award, and each grant may specify in respect of such
specified Management Objectives a minimum acceptable level of achievement and
shall set forth a formula for determining the number of Performance Shares or
Performance Units that will be earned if performance is at or above the minimum
level, but falls short of full achievement of the specified Management
Objectives. The grant of Performance Shares or Performance Units shall specify
that, before the Performance Shares or Performance Units shall be earned and
paid, the Board must certify that the Management Objectives have been satisfied.

                  (d) Each grant shall specify the time and manner of payment of
Performance Shares or Performance Units that have been earned. Any grant may
specify that the amount payable with respect thereto may be paid by the Company
in cash, in shares of Common Stock or in any combination thereof and may either
grant to the Participant or retain in the Board the right to elect among those
alternatives.

                  (e) Any grant of Performance Shares may specify that the
amount payable with respect thereto may not exceed a maximum specified by the
Board at the Date of Grant. Any grant of Performance Units may specify that the
amount payable or the number of shares of Common Stock issued with respect
thereto may not exceed maximums specified by the Board at the Date of Grant.




                                       10

<PAGE>   11



                  (f) The Board may, at or after the Date of Grant of
Performance Shares, provide for the payment of dividend equivalents to the
holder thereof on either a current or deferred or contingent basis, either in
cash or in additional shares of Common Stock.

                  (g) Each grant of Performance Shares or Performance Units
shall be evidenced by an agreement executed on behalf of the Company by any
officer and delivered to and accepted by the Participant, which agreement shall
state that such Performance Shares or Performance Units are subject to all the
terms and conditions of this Plan, and contain such other terms and provisions,
consistent with this Plan, as the Board may approve.


         9. TRANSFERABILITY. (a) Except as otherwise determined by the Board, no
Option Right, Appreciation Right or other derivative security granted under this
Plan shall be transferable by a Participant other than by will or the laws of
descent and distribution. Except as otherwise determined by the Board, Option
Rights and Appreciation Rights shall be exercisable during the Optionee's
lifetime only by him or her or by his or her guardian or legal representative.

                  (b) The Board may specify at the Date of Grant that part or
all of the shares of Common Stock that are (i) to be issued or transferred by
the Company upon the exercise of Option Rights or Appreciation Rights, upon the
termination of the Deferral Period applicable to Deferred Shares or upon payment
under any grant of Performance Shares or Performance Units or (ii) no longer
subject to the substantial risk of forfeiture and restrictions on transfer
referred to in Section 6 of this Plan, shall be subject to further restrictions
on transfer.


         10. ADJUSTMENTS. The Board may make or provide for such adjustments in
the numbers of shares of Common Stock covered by outstanding Option Rights,
Appreciation Rights, Deferred Shares, and Performance Shares granted hereunder,
in the Option Price and Base Price provided in outstanding Appreciation Rights,
and in the kind of shares covered thereby, as the Board, in its sole discretion,
exercised in good faith, may determine is equitably required to prevent dilution
or enlargement of the rights of Participants or Optionees that otherwise would
result from (a) any stock dividend, stock split, combination of shares,
recapitalization or other change in the capital structure of the Company, or (b)
any merger, consolidation, spin-off, split- off, spin-out, split-up,
reorganization, partial or complete liquidation or other distribution of assets,
issuance of rights or warrants to purchase securities, or (c) any other
corporate transaction or event having an effect similar to any of the foregoing.
Moreover, in the event of any such transaction or event, the Board, in its
discretion, may provide in substitution for any or all outstanding awards under
this Plan such alternative consideration as it, in good faith, may determine to
be equitable in the circumstances and may require in connection therewith the
surrender of all awards so replaced. The Board may also make or provide for such
adjustments in the numbers of shares specified in Section 3 of this Plan as the
Board in its sole discretion, exercised in good faith, may determine is
appropriate to reflect any transaction or event described in this Section 10;
provided, however, that any such adjustment to the number specified in Section
3(c)(i) shall be made only if and to the extent that such adjustment would not
cause any Option intended to qualify as an Incentive Stock Option to fail so to
qualify.

<PAGE>   12




         11. CHANGE OF CONTROL. For purposes of this Plan, a "Change of Control"
shall mean if at any time any of the following events shall have occurred:

                  (a) The Company is merged or consolidated or reorganized into
or with another corporation or other legal person, and as a result of such
merger, consolidation or reorganization less than a majority of the combined
voting power of the then-outstanding securities of such corporation or person
immediately after such transaction are held in the aggregate by the holders of
securities entitled to vote generally in the election of Directors immediately
prior to such transaction;

                  (b) The Company sells or otherwise transfers all or
substantially all of its assets to any other corporation or other legal person,
and less than a majority of the combined voting power of the then-outstanding
securities of such corporation or person immediately after such sale or transfer
is held in the aggregate by the holders of shares of Common Stock immediately
prior to such sale or transfer;

                  (c) There is a report filed on Schedule 13D or Schedule 14D-1
(or any successor schedule, form or report), each as promulgated pursuant to the
Exchange Act, disclosing that any person (as the term "person" is used in
Section 13(d)(3) or Section 14(d)(2) of the Exchange Act) has become the
beneficial owner (as the term "beneficial owner" is defined under Rule 13d-3 or
any successor rule or regulation promulgated under the Exchange Act) of
securities representing 20% or more of the Voting Power;

                  (d) The Company files a report or proxy statement with the
Securities and Exchange Commission pursuant to the Exchange Act disclosing in
response to Form 8-K or Schedule 14A (or any successor schedule, form or report
or item therein) that a change of control of the Company has or may have
occurred or will or may occur in the future pursuant to any then-existing
contract or transaction; or

                  (e) If during any period of two consecutive years, individuals
who at the beginning of any such period constitute the Directors cease for any
reason to constitute at least a majority thereof, unless the election, or the
nomination for election by the Company's shareholders, of each Director first
elected during such period was approved by a vote of at least two-thirds of the
Directors then still in office who were Directors at the beginning of any such
period.

                  Notwithstanding the foregoing provisions of Section 11(c) and
(d) above, unless otherwise determined in a specific case by majority vote of
the Board, a "Change of Control" shall not be deemed to have occurred for
purposes of this Plan (i) solely because (A) the Company; (B) a Subsidiary; (C)
the Harris Group; or (D) any Company-sponsored employee stock ownership plan or
any other employee benefit plan of the Company or any Subsidiary either files or
becomes obligated to file a report or proxy statement under or in response to
Schedule 13D, Schedule 14D-1, Form 8-K or Schedule 14A (or any successor
schedule, form or report or item therein) under the Exchange Act, disclosing
beneficial ownership by it of shares, whether in excess of 20%



                                       12

<PAGE>   13



of the Voting Power or otherwise, or because the Company reports that a change
of control of the Company has or may have occurred or will or may occur in the
future by reason of such beneficial ownership or (ii) solely because of a change
of control of any Subsidiary. For purposes of the preceding sentence, the
"Harris Group" shall mean Messrs. Irving B. Harris, Neison Harris, King Harris,
William W. Harris and Sidney Barrows, and their respective spouses, descendants
and spouses of descendants, trustees of trusts established for the benefit of
such persons (acting in their capacity as trustees of such trusts), and
executors of estates of such persons (acting in their capacity as executors of
such estates), and each person of which any of the foregoing owns (i) more than
fifty percent (50%) of the voting stock or other voting interests and (ii) stock
or other interests representing more than fifty percent (50%) of the total value
of the stock or other interests of such person. For purposes of the preceding
sentence, the term "spouses" includes widows and widowers until first remarried.


         12. FRACTIONAL SHARES. The Company shall not be required to issue any
fractional shares of Common Stock pursuant to this Plan. The Board may provide
for the elimination of fractions or for the settlement of fractions in cash.


         13. WITHHOLDING TAXES. To the extent that the Company is required to
withhold federal, state, local or foreign taxes in connection with any payment
made or benefit realized by a Participant or other person under this Plan, and
the amounts available to the Company for such withholding are insufficient, it
shall be a condition to the receipt of such payment or the realization of such
benefit that the Participant or such other person make arrangements satisfactory
to the Company for payment of the balance of such taxes required to be withheld,
which arrangements (in the discretion of the Board) may include relinquishment
of a portion of such benefit. The Company and a Participant or such other person
may also make similar arrangements with respect to the payment of any taxes with
respect to which withholding is not required.


         14. FOREIGN EMPLOYEES. In order to facilitate the making of any grant
or combination of grants under this Plan, the Board may provide for such special
terms for awards to Participants who are foreign nationals or who are employed
by the Company or any Subsidiary outside of the United States of America as the
Board may consider necessary or appropriate to accommodate differences in local
law, tax policy or custom. Moreover, the Board may approve such supplements to
or amendments, restatements or alternative versions of this Plan as it may
consider necessary or appropriate for such purposes, without thereby affecting
the terms of this Plan as in effect for any other purpose, and the Secretary or
other appropriate officer of the Company may certify any such document as having
been approved and adopted in the same manner as this Plan. No such special
terms, supplements, amendments or restatements, however, shall include any
provisions that are inconsistent with the terms of this Plan as then in effect
unless this Plan could have been amended to eliminate such inconsistency without
further approval by the shareholders of the Company.





                                       13

         15. ADMINISTRATION OF THIS PLAN. (a) This Plan shall be administered by
the Board, which may from time to time delegate all or any part of its authority
under this Plan to a committee of the Board (or subcommittee thereof) consisting
of not less than two Directors appointed by the Board. The members of the
committee shall be "Non-Employee Directors" within the meaning of Rule 16b-3 and
"outside directors" within the meaning of Section 162(m) of the Code. A majority
of the committee (or subcommittee) shall constitute a quorum, and the action of
the members of the committee (or subcommittee) present at any meeting at which a
quorum is present, or acts unanimously approved in writing, shall be the acts of
the committee (or subcommittee). To the extent of any such delegation,
references in this Plan to the Board shall be deemed to be references to any
such committee or subcommittee.

                  (b) The interpretation and construction by the Board of any
provision of this Plan or of any agreement, notification or document evidencing
the grant of Option Rights, Appreciation Rights, Restricted Shares, Deferred
Shares, Performance Shares or Performance Units and any determination by the
Board pursuant to any provision of this Plan or of any such agreement,
notification or document shall be final and conclusive. No member of the Board
shall be liable for any such action or determination made in good faith.


         16. AMENDMENTS, ETC. (a) The Board may at any time and from time to
time amend this Plan in whole or in part; provided, however, that any amendment
which must be approved by the shareholders of the Company in order to comply
with applicable law or the rules of the New York Stock Exchange or, if the
shares of Common Stock are not traded on the New York Stock Exchange, the
principal national securities exchange upon which the shares of Common Stock are
traded or quoted, shall not be effective unless and until such approval has been
obtained. Presentation of this Plan or any amendment hereof for shareholder
approval shall not be construed to limit the Company's authority to offer
similar or dissimilar benefits under other plans without shareholder approval.

                  (b) The Board may, with the concurrence of the affected
Participant, cancel any agreement evidencing Option Rights or any other award
granted under this Plan. In the event of such cancellation, the Board may
authorize the granting of new Option Rights or other such awards under this Plan
(which may or may not cover the same number of shares of Common Stock that had
been the subject of the prior award) in such manner, at such Option Price and
subject to such other terms, conditions and discretions as would have been
applicable under this Plan had the canceled Option Rights or other awards not
been granted.

                  (c) The Board also may permit Participants to elect to defer
the issuance of shares of Common Stock or the settlement of awards in cash under
this Plan pursuant to such rules, procedures or programs as it may establish for
purposes of this Plan. The Board also may provide that deferred issuances and
settlements include the payment or crediting of dividend equivalents or interest
on the deferral amounts.

                  (d) The Board may condition the grant of any award or
combination of awards authorized under this Plan on the surrender or deferral by
the Participant of his or her right to



                                       14

<PAGE>   15


receive a cash bonus or other compensation otherwise payable by the Company or a
Subsidiary to the Participant.

                  (e) In case of termination of employment by reason of death,
disability or normal or early retirement, or in the case of hardship or other
special circumstances, of a Participant who holds an Option Right or
Appreciation Right not immediately exercisable in full, or any Restricted Shares
as to which the substantial risk of forfeiture or the prohibition or restriction
on transfer has not lapsed, or any Deferred Shares as to which the Deferral
Period has not been completed, or any Performance Shares or Performance Units
which have not been fully earned, or who holds shares of Common Stock subject to
any transfer restriction imposed pursuant to Section 9(b) of this Plan, the
Board may, in its sole discretion, accelerate the time at which such Option
Right or Appreciation Right may be exercised or the time at which such
substantial risk of forfeiture or prohibition or restriction on transfer will
lapse or the time when such Deferral Period will end or the time at which such
Performance Shares or Performance Units will be deemed to have been fully earned
or the time when such transfer restriction will terminate or may waive any other
limitation or requirement under any such award.

                  (f) This Plan shall not confer upon any Participant any right
with respect to continuance of employment or other service with the Company or
any Subsidiary, nor shall it interfere in any way with any right the Company or
any Subsidiary would otherwise have to terminate such Participant's employment
or other service at any time.

                  (g) To the extent that any provision of this Plan would
prevent any Option Right that was intended to qualify as an Incentive Stock

this Plan.


         17. TERMINATION. No grant shall be made under this Plan more than 10
years after the date on which this Plan is first approved by the shareholders of
the Company, but all grants made on or prior to such date shall continue in
effect thereafter subject to the terms thereof and of this Plan.

         1. PURPOSE. The purpose of the Penton Media, Inc. 1998 Director Stock
Option Plan (the "Plan") is to promote the long-term financial interests of
Penton Media, Inc., a Delaware corporation (the "Company"), and its subsidiaries
by:

         (a) providing an incentive for all non-employee members of the Board of
Directors (the "Non-Employee Directors") to maximize the long-term value of the
Company's Common Stock and otherwise act in the best interest of the Company's
stockholders;

         (b) providing Non-Employee Directors with the opportunity to acquire a
greater stake in the future of the Company and its subsidiaries through stock
ownership; and

         (c) attracting and retaining highly qualified Non-Employee Directors.

         2. DEFINITIONS. The following words and phrases have the respective
meanings indicated below unless a different meaning is plainly implied by the
context.

         (a) "Board of Directors" means the Board of Directors of the Company.

         (b) "Code" means the Internal Revenue Code of 1986, as amended.

         (c) "Common Stock" means Common Stock, par value $.01 per share, of the

         (d) "Eligible Director" means any present or future member of the Board
of Directors who, on the date of an award pursuant to the Plan, (1) is a member
of the Board of Directors, and (2) is not an employee of the Company or any of
its subsidiaries.

         (e) "Market Value" of Common Stock on any date means, for Options
granted during the first twenty days on which the Common Stock is traded on the
New York Stock Exchange, the fair market value of the shares of Common Stock as
determined by the Board of Directors, and, for any subsequent grant of Options,
on any date, means the most recently reported closing price of such Common Stock
on that date on the New York Stock Exchange Composite Transactions list, as
subsequently reported in THE WALL STREET JOURNAL.

         (f) "Option" means a right awarded to a Participant pursuant to the
Plan to purchase a designated number of shares of Common Stock at a stated price
for a stated period of time.

         (g) "Participant" means an Eligible Director who has been awarded an

shall not exceed, in the aggregate, 100,000 shares; it being understood that to
the extent any Options expire unexercised or are cancelled, terminated or
forfeited in any manner without the issuance of shares of Common Stock
thereunder, such shares shall again be available under the Plan. Such 100,000
shares of Common Stock may be authorized and unissued shares, treasury shares,
or a combination thereof, as the Board of Directors shall determine.

         4. OPTIONS. The Board of Directors may grant Options to Eligible
Directors in accordance with this paragraph 4 and the other provisions of the
Plan.

         (a) PROVISIONS.

         (i) Options shall not qualify as incentive stock options within the
meaning of Section 422 of the Code or any successor provision.

         (ii) Options shall have such terms, not to exceed ten years from the
date of grant, as the Board of Directors shall determine at grant.

         (iii) The Option price per share of Common Stock shall be 100% of the
Market Value on the date of grant and not less than the par value of a share of
Common Stock.

         (iv) Options shall be exercisable at such time or times as the Board of
Directors shall determine at or subsequent to grant; provided that, except in
the event of death or disability of the Participant, no Option may be exercised
until the Eligible Director has served on the Board of Directors for at least
six months after it is awarded; further provided that an Option may be exercised
only during a period beginning on the third business day following the date of
release of the Company's quarterly or annual summary statement of sales and
earnings and ending on the fifteenth business day following such date; and
further provided that in the event of termination of service of a Participant as
a member of the Board of Directors for any reason (including without limitation
expiration of term without re-election, resignation, retirement, disability or
death), each Option granted to the Participant shall cease to be exercisable not
later than the fifth anniversary of the date of termination or, if earlier, on
the scheduled date of expiration of such Option.

         (b) EXERCISE. Shares shall be issued to a Participant pursuant to the
exercise of an Option only upon receipt by the Company from the Participant of
written notice of exercise, specifying the number of shares with respect to
which the Option is being exercised, accompanied by payment in full in cash
(including check, bank draft or money order) or, to the extent permitted by the
Board of Directors, by a single exchange of shares of Common Stock already owned
by the Participant for at least six months in an amount equal to the aggregate
Option price for the shares of Common Stock subject to the Option or portion
thereof being exercised or by a combination of such methods; provided that the
Board of Directors may permit the Participant to elect to pay such aggregate
Option price by authorizing a third party to sell the shares of Common Stock
acquired upon exercise (or a sufficient portion thereof) and thereafter remit to
the Company sale proceeds sufficient to pay such aggregate Option price and any
withholding or other tax resulting from exercise. The value of already owned
shares of Common Stock exchanged in full or partial payment for the shares
purchased upon the exercise of an Option shall be equal to the aggregate Market
Value of such already owned shares on the date of the exercise of such Option.

         (c) SURRENDER. If so provided by the Board of Directors at or
subsequent to the time of grant, an Option may be surrendered to the Company on
such terms and conditions, and for such consideration, as the Board of Directors
shall determine.

         (d) FORM. The form of each Option (and of the documentation evidencing
each Option) shall be determined by the Board of Directors.

         5.       MISCELLANEOUS PROVISIONS.

         (a) ADMINISTRATION. The Plan shall be administered by the Board of
Directors. Subject to the limitations of the Plan, the Board of Directors shall
have the sole and complete authority: (i) to select Participants, (ii) to award
Options in such forms and amounts as it shall determine, (iii) to impose such
limitations, restrictions and conditions upon such Options as it shall deem
appropriate, (iv) to interpret the Plan and to adopt, amend and rescind
administrative guidelines and other rules and regulations relating to the Plan,
(v) to correct any defect or omission or to reconcile any inconsistency in the
Plan or in any Options and (vi) to make all other determinations and to take all
other actions necessary or advisable for the implementation and administration
of the Plan. The Board of Directors' determinations on matters within its
authority shall be conclusive and binding upon the Company and all other
persons. All expenses associated with the Plan shall be borne by the Company.

         (b) NON-TRANSFERABILITY. Except as otherwise determined by the Board of
Directors, no Option, and no interest therein, shall be transferable by a
Participant otherwise than by will or the laws of descent and distribution, and
all Options shall be exercisable during a Participant's lifetime only by the
Participant or the Participant's legal representative. Any purported transfer
contrary to this provision will nullify the Option.

         (c) ADJUSTMENT. The Board of Directors may make or provide for such
adjustments in the numbers of shares of Common Stock covered by outstanding
Options granted hereunder as the Board of Directors, in its sole discretion,
exercised in good faith, may determine is equitably required to prevent dilution
or enlargement of the rights of Participants that otherwise would result from
(a) any stock dividend, stock split, combination of shares, recapitalization or
other change in the capital structure of the Company, or (b) any merger,
consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial
or complete liquidation or other distribution of assets, issuance of rights or
warrants to purchase securities, or (c) any other corporate transaction or event
having an effect similar to any of the foregoing. Moreover, in the event of any
such transaction or event, the Board of Directors, in its discretion, may
provide in substitution for any or all outstanding awards under the Plan such
alternative consideration as it, in good faith, may determine to be equitable in
the circumstances and may require in connection therewith the surrender of all
awards so replaced. The Board may also make or provide for such adjustments in
the numbers of shares specified in Section 3 of the Plan as the Board in its
sole discretion, exercised in good faith, may determine is appropriate to
reflect any transaction or event described in this Section 5(c).

         (d) TAX WITHHOLDING. The Board of Directors shall have the power to
withhold, or to require a Participant to remit to the Company, an amount
sufficient to satisfy any withholding or 


                                        3

<PAGE>   4




other tax due with respect to the Participant's exercise of an Option. Subject
to the consent of the Board of Directors, a Participant may make an irrevocable
election to have shares of Common Stock otherwise issuable under an Option
withheld, tender back to the Company shares of Common Stock received pursuant to
an Option or deliver to the Company shares of Common Stock already owned by the
Participant having a Market Value sufficient to satisfy all or part of the
Participant's estimated tax obligations associated with the transaction. Such
election must be made by a Participant prior to the date on which the relevant
tax obligation arises. The Board of Directors may disapprove of any election and
may limit, suspend or terminate the right to make such elections.

         (e) TERMINATION; AMENDMENTS. The Board of Directors may terminate the
Plan at any time. The Board of Directors may amend the Plan at any time or from
time to time; provided that no such amendment shall be made without stockholder
approval to the extent such approval is required by law, regulation or the rules
of any exchange upon which the Common Stock is listed.

                  The Board of Directors may amend an outstanding Option in any
manner to the extent that the Board of Directors would have had the authority
under the Plan to initially grant the Option as so amended.

                  No termination or amendment of the Plan or amendment of any
outstanding Option shall adversely affect any outstanding Option without the
consent of the Participant who holds it.

         (f) RIGHTS OF PARTICIPANTS. Nothing in the Plan shall confer on any
Eligible Director any right to continue to serve as a member of the Board of
Directors or affect in any way the right of the Company to terminate such
service at any time. No Eligible Director shall have a right to be selected as a
Participant, or, having been so selected, to be selected again as a Participant.

         (g) EFFECTIVE DATE. The effective date of the Plan shall be August 7,
1998.

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

                                    ARTICLE 1
                                    ---------

                                  INTRODUCTION
                                  ------------

                  1.1 PURPOSE OF THE PLAN, EFFECTIVE DATE. This Penton Media,
Inc. Retirement Plan (the "plan"), was established effective as of August 7,
1998 (the "effective date") by Penton Media, Inc. (the "company") for the
purpose of providing retirement and other benefits for its eligible employees
and for eligible employees of its subsidiaries and other related companies which
adopt the plan with the consent of the company. The plan represents a
continuation of the Pittway Corporation Retirement Plan (the "Pittway plan") as
to employees or former employees of the company and its current or former
subsidiaries (other than Saddlebrook Resorts, Inc., Saddlebrook International
Tennis, Inc., C & A Investments, Inc. and Pittway Real Estate, Inc)
("transferred participants"). The Combination Agreement dated May 21, 1998,
among the company, Pittway Corporation and other parties (the "Combination
Agreement") provides for a transfer of assets and liabilities attributable to
transferred participants from the Pittway plan to this plan effective as of the
effective date. Subject to the completion of such transfer, all benefit
liabilities with respect to transferred participants attributable to their
covered employment with Pittway Corporation and the employers under the Pittway
plan and attributable to their covered employment under this plan, if any, shall
be provided under this plan, provided that, until the completion of such
transfer, any benefits owed to a transferred participant under this plan shall
be offset by benefits owed to such transferred participant under the Pittway
plan. Benefits provided hereunder as a result of the transfer of assets and
liabilities from the Pittway plan to this plan with respect to periods of
employment prior to the effective date, except as otherwise provided herein,
continue to be governed by the terms of the Pittway plan in effect on the
relevant date. The plan shall be deemed to have become effective on the
effective date following the Distribution described in the Combination
Agreement.
                  1.2 PLAN ADMINISTRATOR, PLAN YEAR. The plan is administered by
a plan committee (the "plan administrator") consisting of not less than three
persons appointed by the company to carry out the administration of the plan.
The plan is administered on the basis of a



                                      - 1 -




<PAGE>   9



plan year (the "plan year") which coincides with the calendar year. Article 10
describes certain specific powers, duties and responsibilities of the plan
administrator with respect to the administration of the plan. For purposes of
the 1998 plan year, the plan year shall begin on the effective date and end on
December 31, 1998.

                  1.3 THE EMPLOYERS. With the consent of the company, the plan
may be adopted in accordance with the provisions of section 11.2 by any
subsidiary of the company or any related company for the benefit of its eligible
employees. The plan is maintained by the company and the related companies that
are set forth in Supplement A to the plan. The company and its subsidiaries and
related companies that adopt the plan are referred to herein collectively as the
"employers" and individually as an "employer." A "subsidiary" means any
corporation 50 percent or more of the voting stock of which is directly or
indirectly owned by the company and a "related company" means any corporation
which directly or indirectly owns 50 percent or more of the voting stock of the
company and any corporation (other than the company and its subsidiaries) 50
percent or more of the voting stock of which is directly or indirectly owned by
any corporation which directly or indirectly owns 50 percent or more of the
voting stock of the company. The term "Penton Companies" includes the employers
and all subsidiaries and related companies that have not adopted the plan (and
each such corporation is sometimes referred to herein individually as a "Penton
Company"). In addition, although only covered employees of an employer that has
adopted the plan may participate in the plan, when determining a participant's
years of service under plan sections 4.3(d), 6.3 or 17.2 or Article 8 solely for
purposes of determining his vested and nonforfeitable interest in his plan
benefits, employment with certain entities that have not adopted the plan will
be taken into account, such that for these purposes, the terms "Penton
Companies" and "employers" shall include any corporation, trade, business or
other separate organization required to be aggregated with the company or other
employer that has adopted the plan under Sections 414(b), (c), (m) or (o) of the
Internal Revenue Code of 1986, as amended (the "Code"), or the regulations
thereunder.
                  1.4 PRESERVATION OF BENEFITS UNDER PREDECESSOR PLANS. Any
other pension plan maintained by an employer may be continued in effect by its
merger into this plan with the consent of the company. If appropriate, special
provisions relating to employees covered under any such



                                      - 2 -




<PAGE>   10


pension plan when it is merged into this plan may be set forth in a supplement
of certification of eligibility which, by amendment, will be attached to and
form a part of this plan. Any pension plan which is merged into this plan, and
the Pittway plan as to transferred participants, may be referred to below as a
"predecessor plan." As to employees who participate in the plan on the effective
date of any merger of all or a portion of a predecessor plan into the plan, it
is intended that the benefits they earned under the predecessor plan up to the
effective date of its merger into this plan shall be preserved unless limited by
Article 9. If the plan administrator determines that any such benefits have not
been provided for under the terms and provisions of the plan as in effect on and
after the effective date of such merger of all or a portion of a predecessor
plan into the plan, the plan administrator shall direct the payment of such
benefits under the plan to the participant or other person entitled to them.

                  1.5 SUPPLEMENTS. In addition to the supplements described in
section 1.4, from time to time supplements or other certifications of
eligibility may by amendment be attached to and form a part of this plan. The
provisions of any such supplements shall be given the same effect that such
provisions would have if they were incorporated in the basic text of the plan.
Supplements may modify the provisions of the plan as they apply to particular
groups of participants. Supplements will specify the persons affected by such
supplements or exhibits and shall supersede the other provisions of the plan to
the extent necessary to eliminate inconsistencies between the plan provisions
and the provisions of such supplements. The terms used in such supplements shall
have the same meanings as those terms have for all other purposes under the plan
and all provisions of the plan not inconsistent with such supplements will
continue to apply to the persons affected by such supplements.

                                PLAN PARTICIPANTS
                                -----------------

                  2.1 ELIGIBILITY. Each employee of an employer on the effective
date who was a participant in the Pittway plan immediately prior to the
effective date will be a participant in the plan on and after the effective
date, subject to the conditions and limitations of the plan. Each other employee
of an employer will become a participant in the plan on the effective date or on
any January 1 thereafter if such employee meets all of the following
requirements:

                           (a) The employee is a "covered employee" (as defined
                  below),

                           (b) The employee has been employed by an employer for
                  at least three full calendar months; provided, however, that
                  he completes one year of eligibility service (as defined in
                  section 2.2) following such January 1.

A "covered employee" shall mean any employee of an employer to which the plan
has been and continues to be extended excluding (i) any employee who is included
in a unit of employees covered by a negotiated bargaining agreement which does
not provide for such employee's participation in the plan, provided that there
is evidence that retirement benefits were the subject of good faith bargaining;
(ii) any non-resident alien with no U.S. source income; (iii) seasonal or
temporary employees whose services for the employers are performed solely from
their homes; and (iv) any leased employee (as defined below)
                  A "leased employee" shall mean any person who, pursuant to an
agreement between an employer and any other person ("leasing organization"), has
performed services for the employer on a substantially full-time basis for a
period of at least one year, and such services are performed under the primary
direction or control of the employer. Contributions or benefits provided a
leased employee by the leasing organization which are attributable to services
performed for an employer will be treated as provided by the employer. A leased
employee will not be considered an employee of an employer, however, if (1)
leased employees do not constitute more than 20 percent of the employer's
nonhighly compensated work force (within the meaning of Section
414(n)(5)(C)(ii)) of the Code, and (2) such leased employee is covered by a
money purchase pension plan maintained by the leasing organization that provides
(i)


                                      - 4 -




<PAGE>   12



a nonintegrated employer contribution rate of at least 10 percent of the
leased employee's compensation, (ii) immediate participation and (iii) full and
immediate vesting.

                  2.2 ELIGIBILITY SERVICE. An employee of an employer shall be
credited with one year of eligibility service if he completes 1,000 or more
hours of service (as defined in section 2.3) during the twelve-consecutive-month
period commencing on his date of hire by the employers or any plan year
following his date of hire. An employee's date of hire shall be the date on
which the employee first completes an hour of service with the employers or with
an employer under the Pittway Plan.

                  2.3      HOURS OF SERVICE.  An "hour of service" means:

                           (a) Each hour for which an employee is directly or
                  indirectly compensated or entitled to be compensated for his
                  performance of duties for the Penton Companies as an employee
                  (with each overtime hour being taken into account as if it
                  were a normal work hour).

                           (b) Each hour for which an employee is directly or
                  indirectly compensated or entitled to be compensated by the
                  Penton Companies with respect to a period of time during which
                  no duties are performed (irrespective of whether the
                  employment relationship has terminated) due to vacation,
                  holiday, illness, incapacitation (including disability),
                  military duty or leave of absence (as defined in section 2.4);
                  provided, however, that not more than 501 hours of service
                  shall be credited to an employee on account of any single
                  continuous period during which he performs no duties (i) if
                  his compensation for such period is in the form of payments
                  made or due under a plan maintained solely for the purpose of
                  complying with applicable worker's compensation, unemployment
                  compensation or state disability insurance laws, (ii) if his
                  compensation for such period constitutes reimbursement for
                  medical or medically related expenses incurred by the
                  employee, or (iii) if his compensation for such period is paid
                  to the employee while on a maternity or paternity leave of
                  absence (as described in subsection 2.4(b) below).

                           (c) Each other hour required by federal law to be
                  counted as an "hour of service," including each such hour for
                  which back pay, irrespective of mitigation of damages, is
                  either awarded or agreed to by the Penton Companies; provided,
                  however, that not more than 501 hours of service shall be
                  credited for payments of back pay, to the extent that such
                  back pay is awarded for a period of time during which the
                  employee did not or would not have performed duties as an
                  employee.

                           (d) Each hour for which an employee is on a maternity
                  or paternity leave of absence in accordance with subsection
                  2.4(b), but only for purposes of preventing the employee from
                  incurring a one-year break in service (as defined in 



                                      - 5 -




<PAGE>   13





                  section 8.3) and only if the employee timely furnishes to the
                  plan administrator such information as it may reasonably
                  require to establish that his absence from work was due to a
                  maternity or paternity leave of absence as defined in
                  subsection 2.4(b) and the number of days for which there was
                  an absence; provided, however, that not more than 501 hours of
                  service shall be credited by reason of a maternity or
                  paternity leave of absence.

Compensated hours described in subsection (b) above shall be determined by
multiplying the number of scheduled work days during the applicable period for
which the employee is compensated by the number of hours in the average
scheduled work day (based on the scheduled work week for his job classification
then in effect, provided, however, that in the case of an employee without a
regular work schedule, such hours shall be computed on the basis of a 40-hour
work week). Hours described in subsection (d) next above for employees on
maternity or paternity leave of absence shall be determined in the same manner
as compensated hours described in subsection (b) next above. In determining
hours of service, hours shall be credited for the period in which such duties
were performed (regardless of when payment is due) or for which such
compensation was paid and for this purpose the rules for crediting hours of
service set forth in section 2530.200b-2 of the Department of Labor regulations
are hereby incorporated by reference; provided that hours of service credited
under subsection (d) next above for a maternity or paternity leave of absence
shall be credited to the year in which such leave begins if such hours are
required to prevent a one-year break in service from occurring in such year, or
if not so required in that year, such hours shall be credited in the immediately
following year. In construing the foregoing provisions of this section,
ambiguities shall be resolved in favor of crediting employees with hours of
service. A transferred participant and any other employee of the Penton
Companies as of the effective date also shall be credited with the same number
of hours of service as were credited to such individual under the Pittway plan
as of the effective date.

                  2.4 LEAVE OF ABSENCE. A "leave of absence" as used in the plan
                  means:

                           (a) A leave of absence required by law or granted by
                  an employer on account of service in military or governmental
                  branches described in any applicable statute granting
                  reemployment rights to employees who enter such branches, or
                  any other military or governmental branch designated by the
                  employer.

                           (b) A leave of absence for any period the employee is
                  absent from work by reason of the employee's pregnancy, the 
                  birth of the child of the employee, the 



                                      - 6 -


<PAGE>   14



                  placement of a child with the employee in connection with the
                  adoption of the child by the employee or the caring for the
                  child for a period beginning immediately after such birth or
                  placement.

                           (c) A leave of absence resulting from the
                  participant's disability (as defined in section 6.2) which is
                  incurred while he is a covered employee of an employer and any
                  other absence from active employment with an employer that is
                  approved by such employer and not treated by it as a
                  termination of employment.

Leaves of absence granted by an employer will be governed by rules uniformly
applied to all employees of that employer similarly situated.

                  2.5 NOTICE OF PARTICIPATION. Each employee will be notified of
the date he becomes a plan participant. Each participant and other person
receiving benefits under the plan will be furnished with a copy of a summary
plan description.

                  2.6 U.S. FOREIGN SERVICE EMPLOYEES. It is intended that a U.S.
foreign service employee (as defined below) may become or remain eligible to
participate in the plan to the same extent as if the employee were employed by
the company. A "U.S. foreign service employee" means a person (i) who is a
citizen of the United States, (ii) who is employed by a subsidiary of the
company incorporated outside the United States that qualifies as a "foreign
subsidiary" as defined in section 406 of the Code, and as to which an employer
has entered into an agreement under section 3121(l) of the Code, and (iii) for
whom contributions under a funded plan of deferred compensation (whether or not
a plan described in section 401(a), 403(a) or 405(a) of the Code) are not
provided by any other person with respect to remuneration paid to such
individual by that subsidiary.

                  RETIREMENT DATES, EMPLOYMENT TERMINATION DATE
                  ---------------------------------------------

                  3.1 NORMAL RETIREMENT DATE. A participant's "normal retirement
date" will be the first day of the calendar month coincident with or next
following the date the participant attains age 65 years ("normal retirement
age").

                  3.2 DEFERRED RETIREMENT DATE. A participant's "deferred
retirement date" will be the first day of the calendar month coincident with or
next following the date of such participant's retirement from the employ of all
of the Penton Companies (as defined in section 1.3) after his normal retirement
date.

                  3.3 EARLY RETIREMENT DATE. A participant's "early retirement
date" will be the first day of the calendar month coincident with or next
following the date of his retirement from the employ of all of the Penton
Companies before his normal retirement date, but after he has both attained age
55 years and completed 10 years of service.

                  3.4 DISABILITY RETIREMENT DATE. A participant's "disability
retirement date" will be the first day of the calendar month coincident with or
next following the date such participant's employment with all of the Penton
Companies terminates on account of his total and permanent disability (as
defined in section 6.2) prior to his normal retirement.

                  3.5 RETIREMENT DATE. Reference to the "retirement date" of a
participant who retires under the plan means his normal retirement date, if his
retirement from the employ of all of the Penton Companies occurs on that date,
but otherwise means his deferred retirement date or his early retirement date,
whichever applies in his case.

                  3.6 EMPLOYMENT TERMINATION DATE. Reference to the "employment
termination date" of a participant whose employment terminates before he
qualifies for retirement on a retirement date means the date his employment with
all of the Penton Companies ceases.

                  3.7 RETIREMENT OR TERMINATION WHILE ON LEAVE OF ABSENCE. A
participant who is otherwise eligible to retire under the plan or who will be
entitled to deferred vested benefits under the plan upon his termination of
employment with the Penton Companies may retire or terminate employment without
returning to active employment with the Penton Companies if he is absent from
work because of a leave of absence (as defined in section 2.4).

                          BENEFIT DETERMINATION FACTORS
                          -----------------------------

                  4.1 GENERAL. A participant's eligibility for, and amount of,
benefits payable under the plan will be based on his years of service, earnings,
covered compensation and annualized covered compensation as determined in
accordance with the provisions of this Article 4, Article 8 and any applicable
supplement to the plan. Years of service, earnings, covered compensation and
annualized covered compensation credited to a transferred participant under the
Pittway plan shall be credited to such transferred participant under this plan.

                  4.2 YEARS OF SERVICE. Subject to the provisions of section 4.3
and Article 8, a participant will be granted one "year of service" for each
calendar year during which such participant completes 1,000 or more hours of
service.
                  4.3 SPECIAL RULES AS TO DETERMINATIONS OF SERVICE. Subject to
the final sentence of Section 4.1, determinations of years of service and hours
of service shall be subject to the provisions of Article 8 and the following
provisions:

                           (a) If a participant had a period or periods of
                  employment with a Penton Company that has not adopted the
                  plan, with a Penton Company before it adopted the plan or with
                  a predecessor company to a Penton Company, such period or
                  periods of employment will be considered as employment with
                  the Penton Companies in determining his hours of service under
                  section 2.1 but will not be considered as employment with the
                  Penton Companies and will be disregarded in determining his
                  years of service under section 4.2 unless and to the extent
                  otherwise required by law or specified by the company;
                  provided that this subsection shall not be applied so as to
                  allow an employee to become a participant prior to his actual
                  employment by an employer and prior to his becoming a covered
                  employee. A "predecessor company" means any other corporation
                  or other entity the stock, assets or business of which was
                  acquired by a Penton Company prior to the effective date or is
                  acquired by a Penton Company on or after the effective date,
                  whether by merger, consolidation, purchase of assets or
                  otherwise, and any predecessor thereto designated by the
                  company.

                           (b) A period of concurrent employment with two or
                  more Penton Companies will be considered as employment with
                  only one of them during that period.

                           (c) A leave of absence (as defined in section 2.4)
                  will not interrupt continuity of employment for purposes of
                  the plan, but hours of service shall be

                                      -9-
<PAGE>   17

                  credited with respect to a paid or unpaid leave of absence
                  only as provided in section 2.3.

                           (d) Separate periods of an employee's employment
                  shall be aggregated for purposes of determining his years of
                  service; provided, however, that if an employee terminates his
                  employment with the employers before he is either eligible to
                  retire on a retirement date or entitled to a deferred vested
                  benefit under section 6.3 and he is reemployed by an employer
                  after he has incurred five consecutive one-year breaks in
                  service (as defined in section 8.3) and his number of
                  consecutive one-year breaks in service exceeds his prior years
                  of service, his prior years of service shall be disregarded.

                  4.4 EARNINGS. Subject to the final sentence of Section 4.1,
for purposes of the plan, a participant's "earnings" means his total, regular
cash compensation paid during the plan year for services rendered to the
employers as a covered employee, including overtime, bonuses, commissions,
incentive compensation, unused vacation pay, and income realized for federal
income tax purposes as a result of the grant or exercise of an option or options
to acquire shares of stock of any Penton Company, the receipt of a cash
appreciation payment in lieu of such an option or options, and the disposition
of shares acquired by the exercise of such an option, but excluding:

                           (a) Any noncash compensation, including any amounts
                  contributed by the employers for the participant's benefit
                  under this plan or any other retirement or benefit plan,
                  arrangement, or policy maintained by the employers; provided,
                  however, any salary reduction amounts elected by the
                  participant and credited to a cafeteria plan (as defined in
                  section 125(c) of the Code) or a qualified cash or deferred
                  arrangement (as defined in section 401(k) of the Code) shall
                  be included in his compensation;

                           (b) Any reimbursements for medical, dental, or travel
                  expenses, automobile allowances, relocation allowances,
                  educational assistance allowances, awards and other special
                  allowances;

                           (c) Any income realized for federal income tax
                  purposes as a result of (i) group life insurance, (ii) the
                  personal use of an employer owned automobile, or
                  (iii) the transfer of restricted shares of stock or restricted
                  property of a Penton Company, or the removal of any such
                  restrictions;

                           (d) Any severance pay paid as a result of the
                  participant's termination of employment;



                                     - 10 -




<PAGE>   18




                           (e) Any compensation paid or payable to the
                  participant, or to any governmental body or agency on account
                  of the participant, under the terms of any state, federal or
                  foreign law requiring the payment of such compensation because
                  of the participant's voluntary or involuntary termination of
                  employment with any Penton Company.

                           (f) Any compensation paid or payable to the
                  participant which is in excess of $150,000 as adjusted by the
                  Commissioner of Internal Revenue for increases in the cost of
                  living in accordance with Section 401(a)(17)(B) of the Code.
                  The cost-of-living adjustment in effect for a calendar year
                  applies to any period, not exceeding 12 months, over which
                  compensation is determined (determination period) beginning in
                  such calendar year. If a determination period consists of
                  fewer than 12 months, the annual compensation limit will be
                  multiplied by a fraction, the numerator of which is the number
                  of months in the determination period, and the denominator of
                  which is 12. Any reference in this plan to the limitation
                  under section 401 (a)(17) of the Code shall mean the annual
                  compensation limit set forth in this provision. If
                  compensation for any prior determination period is taken into
                  account in determining an employee's benefits accruing in the
                  current plan year, the compensation for that prior
                  determination period is subject to the annual compensation
                  limit in effect for that prior determination period.

                  4.5 DETERMINATION OF BASES OF BENEFITS. A participant's hours
of service, years of service, earnings, and any other factor relating to
benefits payable to him under the plan shall be determined by the plan
administrator pursuant to the foregoing provisions of this Article 4, Article 9
and any supplement to the plan on the basis of the records of the employers and
on the basis of reasonable estimates where such records are not sufficient to
provide all required data and information.

                  4.6 MILITARY SERVICE. Notwithstanding any provisions of this
plan to the contrary, contributions, benefits and service credit with respect to
qualified military service will be provided in accordance with Section 414(u) of
the Code. "Qualified military service" means any service in the uniformed
services (as defined in chapter 43 of title 38 of the United States
Code) by any individual if such individual is entitled to reemployment rights
under such chapter with respect to such service.

                                RETIREMENT INCOME
                                -----------------

                  5.1 NORMAL OR DEFERRED RETIREMENT. Subject to the conditions
and limitations of the plan, if a participant retires on his normal retirement
date or a deferred retirement date he will be entitled to a monthly retirement
income payable for the life of the participant commencing on his retirement date
in an amount equal to one-twelfth of the sum of the participant's accrued
benefits for each plan year that he participated in the plan. Subject to the
conditions and limitations of this section 5.1, each plan year up to 35 years of
plan participation, the participant's accrued benefit shall equal (a) plus (b)
below:
                           (a) 1.2 percent of his earnings for such plan year up
                  to covered compensation (as defined below).

                           (b) 1.85 percent of his earnings for such plan year
                  in excess of covered compensation.

For purposes of this section 5.1, a participant's "covered compensation" is
equal to the average of the Social Security taxable wage bases in effect for
each calendar year (under Table II of the tables issued each year by the Social
Security Administration) during the 35-year period ending with the last day of
the calendar year in which the participant attains (or will attain) Social
Security retirement age (as defined in Section 415(b)(8) of the Code). If the
participant's employment terminates prior to his Social Security retirement age,
then for purposes of determining the participant's covered compensation amount
it shall be assumed that the taxable wage base for the plan year of the
determination shall continue in effect for each subsequent plan year. If the
participant's employment terminates after his Social Security retirement age,
then a participant's covered compensation for a plan year shall be equal to the
covered compensation as determined for the plan year during which he attained
his Social Security retirement age. For each plan year, a participant's
applicable "covered compensation" shall be based on the applicable Social
Security wage base for individuals born in the year of the participant's birth
as set forth in the foregoing Table II. With respect to a participant who has
completed more than 35 years of plan participation, each plan year of plan
participation that exceeds 35 such years, the participant's accrued benefit for
such plan year shall be an amount equal to:



                                     - 12 -




<PAGE>   20



                           1.2 percent of his earnings for such plan year.

A participant's accrued benefit with respect to the plan year in which his
retirement date or employment termination date occurs shall be based on (X) his
actual earnings for such plan year but annualized as though his retirement date
or employment termination date had occurred on the last day of such plan year,
(Y) the amount of such annualized earnings that would constitute the
participant's covered compensation for such plan year had the participant
actually earned such annualized amount (the "annualized covered compensation"),
and (Z) the excess of the participant's annualized earnings over his annualized
covered compensation for such plan year. The participant's accrued benefit for
such plan year shall be an amount equal to the sum of (i) plus (ii) with such
sum multiplied by (iii), where (i), (ii), and (iii) are as follows:

                           (i)      1.2 percent of annualized earnings up to
                                    annualized covered compensation.

                           (ii)     1.85 percent of annualized earnings in
                                    excess of annualized covered compensation.

                           (iii)    A fraction the numerator of which is the
                                    number of full months of service the
                                    participant completed in the plan year in
                                    which his retirement date or employment
                                    termination date occurs and the denominator
                                    of which is 12.

With respect to a participant who has completed 35 or more years of plan
participation, the foregoing computation of his accrued benefit for his final
plan year of participation shall be based on 1.2 percent of his annualized
earnings multiplied by the fraction set forth in (iii) above. A participant's
right to his normal retirement benefit shall be nonforfeitable and fully vested
when he attains normal retirement age or when his employment with the employers
terminates by reason of his total and permanent disability (as defined in
Section 6.2).

                  5.2 EARLY RETIREMENT. Subject to the conditions and
limitations of the plan, if a participant retires on an early retirement date he
will be entitled to a monthly retirement income commencing on his normal
retirement date and payable in the normal form in an amount equal to
his retirement benefit on his early retirement date as determined under section
5.1. However, in lieu of receiving a monthly retirement income commencing on his
normal retirement date, the participant may elect (by filing a written election
with the plan administrator in advance) to


                                     - 13 -




<PAGE>   21



receive a monthly retirement income commencing at his early retirement date, or
on the first day of any calendar month thereafter that occurs before his normal
retirement date. If such monthly retirement income is to commence prior to the
date the participant attains his normal retirement age, the amount of such
monthly retirement income that he would otherwise be entitled to on his normal
retirement date shall be reduced by 1/180 for each of the first 60 months and
1/360 for each of the next 60 months by which the commencement of the payment of
the retirement income precedes his normal retirement age.

                  5.3 FORM OF PAYMENT. If a participant becomes entitled to
receive a retirement income benefit under the foregoing provisions of this
Article 5, payment of such benefit shall be made in accordance with, and subject
to, the applicable provisions of Article 7.

                                    ---------

                   DISABILITY BENEFIT; DEFERRED VESTED BENEFIT
                   -------------------------------------------

                  6.1 DISABILITY BENEFIT. Subject to the conditions and
limitations of the plan, if a participant's employment with all of the Penton
Companies is terminated before he becomes eligible for early or normal
retirement because of his total and permanent disability (as defined in section
6.2), he will be entitled to a monthly disability benefit commencing on his
disability retirement date regardless of whether he has completed five years of
service as of such date. The amount of his monthly disability benefit will be
computed in accordance with the benefit formula in section 5.1 above (as in
effect as of his disability retirement date) as of his disability retirement
date but shall be actuarially reduced to account for commencement on his
disability retirement date. In lieu of receiving his monthly disability benefit
commencing on his disability retirement date, a participant may elect (by filing
a written election with the plan administrator in advance) to receive his
monthly disability benefit commencing on the first day of any calendar month
commencing on or after his disability retirement date that occurs before his
normal retirement date, subject to actuarial reduction. Notwithstanding anything
in this section 6.1 or the plan to the contrary, no monthly disability benefit
shall be payable for any month for which the participant receives long-term
disability benefits under a disability benefit program maintained by his


                                     - 14 -

employer. The participant's monthly disability benefit will be payable only to
him, on a life annuity basis, pursuant to the applicable provisions of Article
7, subject to the following:

                           (a) If the participant recovers from his disability
                  prior to his normal retirement date, if he should no longer be
                  entitled to disability insurance benefits under the Social
                  Security Act or if he should refuse to submit evidence to the
                  plan administrator of his disability, his entitlement to his
                  monthly disability benefit shall cease. Unless he then is
                  reemployed by an employer, he shall be deemed to have
                  terminated employment on his actual employment termination
                  date for a reason other than disability. His eligibility for,
                  and the amount of, benefits payable to him under the plan
                  after his recovery from his disability shall be determined in
                  accordance with section 6.3 and the benefit formula in section
                  5.1 (as in effect as of his actual employment termination date
                  and as if such date were a retirement date) as of his actual
                  employment termination date and his accrued benefits under the
                  plan shall be reduced by the actuarial value of the disability
                  benefits he previously received under the plan.

                           (b) If the participant does not recover from his
                  disability prior to his normal retirement age and is not
                  married as of his normal retirement age, his monthly
                  disability benefit shall be payable to him on a life annuity
                  basis until his attainment of normal retirement age and his
                  normal retirement benefit (as actuarially reduced to account
                  for his benefits having commenced prior to his normal
                  retirement date) shall continue to be payable to him in the
                  form of a life annuity thereafter (unless the participant
                  rejects the life annuity form of benefit in accordance with
                  the provisions of sections 7.1 and 7.3).

                           (c) If the participant has completed 10 years of
                  service but has not attained age 55 years as of his disability
                  retirement date, does not recover from his disability prior to
                  his attainment of age 55 years, and is married as of the date
                  he attains age 55 years, his monthly disability benefit (as
                  actuarially reduced to account for his benefits having
                  commenced prior to his normal retirement date) shall be
                  payable to him on a life annuity basis until his attainment of
                  age 55 years and shall be payable in the form of a qualified
                  joint and survivor annuity thereafter (unless the participant
                  and his spouse reject the qualified joint and survivor annuity
                  form of benefit in accordance with the provisions of sections
                  7.1 and 7.3). If such a participant dies prior to his
                  attainment of age 55 years and he has an eligible spouse (as
                  defined in Section 7.4) as of the date of his death, his
                  surviving eligible spouse shall be eligible for a
                  pre-retirement spouse's benefit as set forth in section 7.4.

                           (d) If the participant has completed five but less
                  than 10 years of service as of his disability retirement date,
                  does not recover from his disability prior to his attainment
                  of normal retirement age, and is married as of the date he
                  attains his normal retirement age, his monthly disability
                  benefit (as actuarially reduced to



                                     - 15 -




<PAGE>   23



                  account for his benefits having commenced prior to his normal
                  retirement date) shall be payable to him on a life annuity
                  basis until his attainment of normal retirement age and his
                  normal retirement benefit shall be payable in the form of a
                  qualified joint and survivor annuity thereafter (unless the
                  participant and his spouse reject the qualified joint and
                  survivor annuity form of benefit in accordance with the
                  provisions of sections 7.1 and 7.3). If such a participant
                  dies prior to his attainment of normal retirement age and he
                  has an eligible spouse (as defined in section 7.4) as of the
                  date of his death, his surviving eligible spouse shall be
                  eligible for a pre-retirement spouse's benefit as set forth in
                  Section 7.4.

                  6.2 DISABILITY. A participant shall be considered to have
incurred a "total and permanent disability" for purposes of the plan if he
qualifies for and is receiving disability benefits under the Social Security Act
or he qualifies for and is receiving long-term disability benefits under any
disability benefit program maintained by his employer. For the purpose of
determining whether a participant has incurred a total and permanent disability
or has recovered from a total and permanent disability, the plan administrator
from time to time may require that a participant either verify that he currently
qualifies for and is receiving disability benefits under the Social Security Act
or submit to medical examinations at any reasonable time (but not more
frequently than twice in a twelve-month period) prior to his normal retirement
date. The plan administrator's determination of the existence of a disability
and of the medical evidence necessary and appropriate to determine its existence
shall be conclusive.

                  6.3 MONTHLY DEFERRED VESTED BENEFIT. Subject to the conditions
and limitations of the plan, if a participant resigns or is dismissed from the
employ of all of the employers before he qualifies for retirement under the plan
after he has completed five or more years of service, or if his employment with
the employers terminates by reason of his disability (as defined in section
6.2), he will be eligible to receive a monthly deferred vested benefit for life
commencing on his normal retirement date. The amount of his monthly deferred
vested benefit will be computed in accordance with the benefit formula described
in section 5.1 (as in effect as of his employment termination date as if such
date were a retirement date) as of his employment termination date.

                  6.4 EARLY COMMENCEMENT OF DEFERRED VESTED BENEFIT. A
participant who is entitled to a monthly deferred vested benefit may elect (by
filing a written election with the plan administrator in advance) to receive, in
lieu of a monthly deferred vested benefit commencing at

                                     - 16 -




<PAGE>   24



his normal retirement date, a monthly deferred vested benefit commencing on or
after the first day of any month on or after the date the participant attains
age 55 and has completed 10 years of service and prior to his normal retirement
date. If a participant elects early commencement of his monthly deferred vested
benefit the amount of such monthly deferred vested benefit shall be determined
by reducing the amount of monthly deferred vested benefit to which the
participant is otherwise entitled commencing on his normal retirement date by
1/180 for each of the first 60 months and 1/360 for each of the next 60 months
by which the commencement of his benefits precedes his normal retirement date.

                  6.5 ANNUITY COMMENCEMENT DATE. A participant's "annuity
commencement date" means the date as of which the initial payment of the
retirement income or deferred vested benefit to which he is entitled under the
plan is payable.

                  6.6 FORM OF PAYMENT. If a participant becomes entitled to
receive a deferred vested retirement income benefit under the foregoing
provisions of this Article 6, payment of such benefit shall be made in
accordance with, and subject to, the applicable provisions of Article 7.


                                    ARTICLE 7
                                    ---------

                 PAYMENT OF RETIREMENT INCOME AND OTHER BENEFITS
                 -----------------------------------------------

                  7.1 NORMAL FORM OF PAYMENT OF BENEFITS. Except as otherwise
specifically provided, payment of participants' monthly retirement income or
deferred vested benefits under Articles 5 and 6 shall be made to them, and
payment of monthly benefits shall be made to their spouses, if eligible for such
benefits, as follows:

                           (a) QUALIFIED JOINT AND SURVIVOR ANNUITY. If a
                  participant retires on a normal, early or deferred retirement
                  date under the plan, or if a participant's employment
                  terminates before retirement under the plan and he is entitled
                  to a deferred vested benefit, and if the participant has an
                  eligible spouse (as defined in section 7.4) immediately
                  preceding his annuity commencement date, payment of his
                  monthly benefit shall be in the form of a "qualified joint and
                  survivor annuity" unless he had elected in lieu thereof to
                  receive payment either in the form of a life annuity under
                  subsection (b) next below or under a benefit option described
                  in section 7.2 (and such option is in effect on his annuity
                  commencement date). Such qualified joint and survivor annuity
                  shall consist of a monthly benefit continuing during the
                  participant's lifetime and if the participant's eligible
                  spouse is living at the time of the participant's death,
                  payment of 50 percent of such monthly benefit


                                     - 17 -




<PAGE>   25



                  shall be made to his eligible spouse until the eligible
                  spouse's death occurs. The amount of such monthly benefit
                  under this subsection shall be calculated so that it is the
                  actuarial equivalent of the retirement or deferred vested
                  benefit to which the participant is otherwise entitled. If a
                  participant who has five or more years of service who retired
                  on a normal or early retirement date dies prior to his annuity
                  commencement date, or if a participant who has continued
                  employment after he has attained normal retirement age dies
                  before his retirement date, and if such participant has an
                  eligible spouse at the time of his death, then, unless the
                  participant had elected that benefits not be paid to his
                  eligible spouse under this subsection, benefits shall be
                  payable to the participant's eligible spouse in accordance
                  with the foregoing provisions of this subsection as if the
                  participant's annuity commencement date had occurred
                  immediately prior to the date of his death.

                           (b) LIFE ANNUITY. A participant shall receive payment
                  of his monthly benefit during his lifetime on a life annuity
                  basis if he is not eligible for a qualified joint and survivor
                  annuity under subsection (a) next above, or, if he is eligible
                  for a qualified joint and survivor annuity under (a) above,
                  and prior to his annuity commencement date he had elected not
                  to receive payment in the form of a qualified joint and
                  survivor annuity or any of the optional forms of payment of
                  benefits described in section 7.2.

                           (c) WRITTEN EXPLANATION OF QUALIFIED JOINT AND
                  SURVIVOR ANNUITY: The plan administrator shall provide to each
                  participant, not more than 90 days nor less than 7 days before
                  the participant's annuity starting date, a written explanation
                  of (i) the terms and conditions of the qualified joint and
                  survivor annuity, (ii) the participant's right to make, and
                  the effect of, an election to waive the qualified joint and
                  survivor annuity, (iii) the rights of a participant's spouse
                  under this section, (iv) the right to make, and the effect of,
                  a revocation of an election to waive the qualified joint and
                  survivor annuity and (v) a general description of the
                  eligibility features and relative values of a qualified joint
                  and survivor annuity, single life annuity and the other
                  optional forms of benefit under the plan. Each participant
                  shall have an election period beginning not more than 90 days
                  before his annuity commencement date and ending on the annuity
                  commencement date. An election made by the participant under
                  subsection (a) next above may be revoked by the participant,
                  and a new election made at any time during the election
                  period, providing that such a new election meets the
                  requirements of section 7.3.

                  7.2 OPTIONAL FORMS OF PAYMENT OF BENEFITS. In lieu of the
normal form and amount of monthly benefit specified in section 7.1, and subject
to the provisions of section 7.3, a participant before his retirement date
(excluding a participant entitled to a monthly disability 


                                     - 18 -




<PAGE>   26

benefit) may elect a retirement income or deferred vested benefit of actuarially
equivalent value in one of the following forms:

                           (a) FIVE, TEN OR FIFTEEN YEAR CERTAIN OPTION. A
                  monthly benefit payable to the participant during his lifetime
                  and, if the participant dies within a period of five, ten or
                  fifteen years (as selected by the participant) from his
                  annuity commencement date, a continuing monthly payment of the
                  same amount to a person or persons designated by the
                  participant for the balance of such five, ten or fifteen year
                  period; provided, however, that the ten or fifteen years
                  option shall not be available if the life expectancy of the
                  participant or the joint and survivor life expectancy of the
                  participant and his beneficiary is less than the applicable
                  five, ten or fifteen years on his annuity commencement date.

                           (b) JOINT AND SURVIVOR ANNUITY. A monthly benefit
                  payable to the participant during his lifetime and, if another
                  person he had designated is living at the time of his death,
                  payment of 100 percent, 66-2/3 percent or 50 percent of that
                  amount to such other person as long as such other person
                  lives; provided, however that if the participant designates
                  someone other than his spouse, the option shall be designed so
                  that the lump sum actuarially equivalent value of the monthly
                  benefit payable to the participant under the option over his
                  life expectancy shall be greater than 50 percent of the lump
                  sum actuarially equivalent value of the monthly benefit that
                  otherwise would be payable to the participant on a life
                  annuity basis.

                           (c) LEVEL BENEFIT OPTION. If payment of a
                  participant's monthly benefit begins before he commences
                  receiving Old Age Insurance Benefits under the Social Security
                  Act, a larger monthly retirement income or deferred vested
                  benefit payable to him until the first to occur of his death
                  or the earliest date on which he becomes eligible to apply for
                  and receive Old Age Insurance Benefits under the Social
                  Security Act, and, where the full actuarial equivalent of the
                  normal form of the participant's monthly benefit has not been
                  provided under the option, with a continuance of a smaller
                  amount of monthly benefit after such date until the
                  participant's death.

                           (d) LUMP SUM OPTION. A single lump sum payment of the
                  actuarially equivalent present value of the participant's
                  monthly retirement benefit.

                           (e) FULL CASH REFUND OPTION. A monthly benefit
                  payable to the participant during his lifetime and, if the
                  participant dies before he has received payments equal to the
                  actuarial value of his pension at the earlier of his normal
                  retirement date or annuity commencement date, then the excess
                  of such amount over the amount received by the participant
                  shall be paid in a lump sum or life annuity to a person or
                  persons designated by the participant.



                                     - 19 -

Elections under this section shall be in writing on forms prescribed by and
filed with the plan administrator.

                  7.3 RULES AS TO WAIVER OF NORMAL FORM OF BENEFIT, ELECTION AND
DISCONTINUANCE OF OPTIONAL FORMS OF PAYMENT OF BENEFITS AND SPOUSAL CONSENTS. A
participant's waiver of a normal form of benefit and election of an optional
form of monthly benefit specified in section 7.2 and an eligible spouse's
consent of the participant's waiver and election shall be subject to the
following rules, to the extent appropriate:

                           (a) A waiver of the normal form of benefit and
                  election of an optional form of benefit must be in writing,
                  signed by the participant, and approved by the company. If
                  payment of the participant's monthly benefit otherwise would
                  be required pursuant to subsection 7.1(a), the election of an
                  optional form of benefit will not be valid unless (i) it also
                  contains the participant's waiver of his right to receive
                  payment in the form of a qualified joint and survivor annuity
                  and (ii) the participant's eligible spouse consents, in
                  writing, to the participant's waiver of the normal form of
                  benefit, to the optional form of benefit or the plan
                  administrator determines that a consent cannot be obtained
                  because the participant is not married or because the eligible
                  spouse cannot be located or because of such other
                  circumstances as the Secretary of the Treasury may, by
                  regulation, prescribe. An eligible spouse's consent is
                  irrevocable and must be witnessed by a notary public or a plan
                  representative.

                           (b) A participant may waive the normal form of
                  benefit and elect an optional form of benefit, and an eligible
                  spouse may consent to such a waiver and election, at any time
                  during the applicable election period. The applicable election
                  period shall commence on the date which is 90 days prior to
                  the participant's annuity commencement date and shall end on
                  the participant's annuity commencement date.

                           (c) A participant who has elected an option may
                  revoke it or change it to another option at any time prior to
                  the participant's annuity commencement date by filing, with
                  the plan administrator, a superseding election, in accordance
                  with the foregoing provision of this section 7.3. A revocation
                  or change of an option may be made without the consent of the
                  person or persons the participant has designated in the
                  option. Notwithstanding the immediately preceding provision, a
                  participant's eligible spouse must consent, in accordance with
                  the foregoing provision of this section 7.3, to a change of an
                  optional form of benefit.

                           (d) If a participant who had elected an option dies
                  before he attains age 65 and before his annuity commencement
                  date, such option automatically will be canceled and no
                  benefits will be paid to any person (or any person's estate)
                  under



                                     - 20 -


<PAGE>   28




                  such option. If a participant dies after attaining age 65, but
                  before his benefit commencement date, such option will
                  continue in effect as if the participant retired immediately
                  prior to his death.

                           (e) If the beneficiary designated by a participant in
                  his election of an option dies before the participant's
                  annuity commencement date, the option automatically will be
                  canceled and the participant's monthly benefit will be paid to
                  him in the normal form unless a new election can be and is
                  made by the participant pursuant to the foregoing provisions
                  of this section.

                           (f) If after a participant has commenced receiving
                  monthly benefits under subsections 7.2(a) or (e), but prior to
                  the participant's death, the person or persons designated by
                  the participant under that subsection die, the option shall
                  remain in effect and, unless the participant designates
                  another beneficiary to receive any benefits payable under that
                  option after his death, such benefits shall be payable to the
                  participant's estate. If after a participant has commenced
                  receiving monthly benefits under subsection 7.2(b), but prior
                  to the participant's death the beneficiary designated as the
                  joint annuitant by the participant under that subsection dies,
                  the option shall remain in effect but no benefits shall become
                  payable to any person (or any person's estate) upon the
                  participant's death.

                  7.4 PRE-RETIREMENT SPOUSE'S BENEFIT. If a participant who has
completed five or more years of service dies before his annuity commencement
date and if he has an eligible spouse at the time of his death, his eligible
spouse shall be entitled to receive a monthly benefit for life. The monthly
benefit payable to the participant's eligible spouse for life shall be an amount
equal to 50 percent of the amount of monthly retirement income or monthly
deferred vested benefit that would have been payable to the participant under
subsection 7.1(a) in the form of the qualified joint and survivor annuity
described therein if he had terminated employment as of the date of his death
(if he had not already so terminated his employment) and his annuity
commencement date was to occur on the first day of the calendar month coincident
with or next following the later of the date of his death or the date the
participant would have attained normal retirement age with the qualified joint
and survivor annuity in effect for him. The first payment to a participant's
eligible spouse under this section shall be made as of the first day of the
calendar month coincident with or next following the later of the date of the
participant's death or the date the participant would have attained age 65
years, and the final payment shall be made as of the first day of the calendar
month during which the eligible spouse's death occurs. In lieu of



                                     - 21 -

receiving a monthly benefit commencing on the participant's normal retirement
date, an eligible spouse of a participant who had completed 10 years of service
as of the date of his death may elect (by filing a written election with the
plan administrator in advance) to receive a monthly benefit for life commencing
on the first day of the calendar month coincident with or next following the
later of the date of the participant's death or the date the participant would
have been eligible for early retirement, or on the first day of any calendar
month thereafter that occurs prior to the participant's normal retirement date.
If such monthly benefit is to commence prior to the participant's normal
retirement date, the amount of such monthly benefit shall be determined by
reducing the amount of monthly benefit to which the eligible spouse would
otherwise be entitled commencing on the participant's normal retirement date by
1/180 for each of the first 60 months and 1/360 for each of the next 60 months
by which the commencement of the monthly benefit precedes the participant's
normal retirement date. Notwithstanding anything in this section 7.4 or the plan
to the contrary, if a participant who has completed five or more years of
service continues in the employ of the employers after he has attained age 65
years and the participant is married, the participant may elect prior to his
retirement (in writing on a form prescribed by and filed with the plan
administrator prior to the participant's death) to have the lump sum actuarially
equivalent present value of his monthly retirement benefit paid to his eligible
spouse, if any, as soon as practicable after his death provided that he dies
prior to his annuity commencement date and his spouse consents in writing to
such immediate lump sum payment in accordance with the spousal consent rules
described in section 7.3(a). The spouse of a participant will be considered as
an "eligible spouse" as of any date only if at least twelve months prior thereto
the participant and spouse are married in a religious or civil ceremony
recognized under the laws of the state where the marriage was contracted and the
marriage remains legally effective.

                  7.5 SPECIAL PRE-RETIREMENT LUMP SUM DEATH BENEFIT. A
participant who continues in the employ of the Penton Companies after his
attainment of normal retirement age may elect the lump sum benefit payment
described in section 7.2(d) as a pre-retirement death benefit to his designated
beneficiary. If a participant elects a lump sum pre-retirement death benefit
under this section, dies prior to his employment termination date or retirement
date and has not revoked his election as of the date of his death, payment of
the lump sum shall be made to



                                     - 22 -




<PAGE>   30





the participant's designated beneficiary; provided, however, that if the
participant has an eligible spouse as of the date of the participant's death,
the eligible spouse shall receive the pre-retirement spouse's benefit described
in section 7.4 and the participant's election of a lump sum pre-retirement death
benefit described in this section shall be canceled unless the participant's
eligible spouse consents (within the 90-day period ending on the benefit
commencement date in accordance with the procedures described in section 7.3) to
the payment of such lump sum benefit to the participant's designated beneficiary
in lieu of the pre-retirement spouse's benefit. Any election made under this
section 7.5 shall be canceled upon the participant's employment termination
provided the participant's employment terminates by reason other than his death.

                  7.6 SPECIAL PAYMENT LIMITATIONS. Notwithstanding anything in
this plan to the contrary,

                           (a) As provided in section 401(a)(9) of the Code, (i)
                  in the case of a participant who (A) is a five-percent owner
                  or (B) attains age 70 1/2 prior to January 1, 1999, the
                  payment of such participant's benefits shall in no event
                  commence later than April 1 of the calendar year following the
                  calendar year in which the participant attains age 70 1/2 and
                  (ii) in the case of any other participant, the payment of such
                  participant's benefit shall in no event commence later than
                  April 1 of the calendar year following the later of the
                  calendar year in which the participant attains age 70 1/2 or
                  the calendar year in which the participant terminates
                  employment with the employers;

                           (b) If the actuarial present value of a participant's
                  vested accrued benefits exceeds, or at any time exceeded,
                  $5,000, no amount shall be distributable to the participant
                  prior to the date the participant attains normal retirement
                  age without the participant's written consent and, if the
                  participant's benefit is to be distributed in any form other
                  than a qualified joint and survivor annuity, the written
                  consent of the participant's eligible spouse;

                           (c) Payment of benefits under the plan to a
                  participant shall commence not later than the 60th day after
                  the end of the plan year in which occurs the latest of the
                  participant's termination of employment with the employer, the
                  participant's attainment of normal retirement age, or the
                  tenth anniversary of the year in which the participant
                  commenced participation in the plan; and

                           (d) If a participant continues in the employ of the
                  Penton Companies after his normal retirement date, the payment
                  of his accrued monthly retirement income shall be suspended
                  only for those calendar months within the period of his
                  continued employment during which he receives compensation for
                  at least 40

                                     - 23 -




<PAGE>   31



                  hours of service as long as proper notification of such
                  suspension of benefits has previously been distributed to such
                  participant.

                  7.7 PAYMENT OF SMALL AMOUNTS. If the lump sum actuarially
equivalent value of the monthly benefit payable to or with respect to a
participant under the plan does not exceed $5,000 as of the participant's
employment termination date, then, in lieu of payment of such monthly benefits,
the plan administrator shall direct that an amount equal to the lump sum
actuarially equivalent value of such monthly benefits be paid to the participant
(or, in the event of the participant's death, to the participant's beneficiary)
in a lump sum as soon as practicable thereafter; and for this purpose, if the
value of the participant's vested and nonforfeitable benefit under the plan as
of the participant's employment termination date is zero, the participant shall
be deemed to have received a total distribution of such vested and
nonforfeitable benefit as of such date. For purposes of determining the lump sum
amount under this section, the interest rate used in determining actuarial
equivalence shall not be greater than the interest rate which would be used as
of the date of a distribution under this section by the Pension Benefit Guaranty
Corporation ("PBGC") for purposes of determining the present value of a lump sum
distribution under a plan which terminates on such date.

                  7.8 PAYMENT BY ANNUITY PURCHASE. The purchase for a
participant, contingent annuitant or beneficiary and distribution to that person
of an annuity contract or annuity certificate to provide such person's benefits
shall constitute the complete payment of that person's benefits under the plan.

                  7.9 DIRECT ROLLOVER OF ELIGIBLE ROLLOVER DISTRIBUTIONS.
Notwithstanding any provision of the plan to the contrary that would otherwise
limit a distributee's election under this Article 7, a distributee may elect, at
the time and in the manner prescribed by the plan administrator, to have any
portion of an eligible rollover distribution paid directly to an eligible
retirement plan specified by the distributee in a direct rollover.

                  An "eligible rollover distribution" is any distribution of all
or any portion of the balance to the credit of the distributee, except that an
eligible rollover distribution does not include: any distribution that is one of
a series of substantially equal periodic payments (not less frequently than
annually) made for the life (or life expectancy) of the distributee or the joint
lives



                                     - 24 -




<PAGE>   32





(or joint life expectancies) of the distributee and the distributee's designated
beneficiary, or for a specified period of ten years or more; any distribution to
the extent such distribution that is not includable in gross income (determined
without regard to the exclusion for net unrealized appreciation with respect to
employer securities).

                  An "eligible retirement plan" is an individual retirement
account described in section 408(a) of the Code, an individual retirement
annuity described in section 408(b) of the Code, an annuity plan described in
section 403(a) of the Code, or a qualified trust described in section 401(a) of
the Code, that accepts the distributee's eligible rollover distribution.
However, in the case of an eligible rollover distribution to the surviving
spouse, an eligible retirement plan is an individual retirement account or
individual retirement annuity.

                  A "distributee" includes an employee or former employee. In
addition, the employee's or former employee's surviving spouse and the
employee's or former employee's spouse or former spouse who is the alternate
payee under a qualified domestic relations order, as defined in section 414(p)
of the Code, are distributees with regard to the interest of the spouse or
former spouse.

                  A "direct rollover" is a payment by the plan to the eligible
retirement plan specified by the distributee.

                  7.10 DESIGNATED BENEFICIARIES. A participant may from time to
time designate a beneficiary or beneficiaries on a form provided by the plan
administrator, to whom the participant's benefit will be distributed following
the participant's death. A participant may designate contingent or successive
beneficiaries and may name individuals, legal persons or entities, trusts,
estates, trustees or other legal representatives as beneficiaries. Beneficiary
designations must be completed and filed with the plan administrator during the
participant's lifetime, and, if the participant has an eligible spouse at the
date of the participant's death, the participant's surviving spouse will be the
participant's designated beneficiary unless the surviving spouse has consented
or consents in writing to the participant's designation of another beneficiary
in accordance with section 7.3. The consent of the spouse shall not be required
to the participant's designation of a beneficiary upon proof satisfactory to the
plan administrator that the participant is not married, the spouse of the
participant cannot be located, or the consent of the



                                     - 25 -




<PAGE>   33





spouse cannot be obtained under such circumstances as may be prescribed in
regulation issued by the Secretary of Treasury or its delegate. A beneficiary
designation properly completed and filed will cancel all such designations filed
earlier.

                  7.11 MISSING PERSONS. Each participant and each other person
entitled to benefits under the plan must file with the plan administrator from
time to time in writing his post office address and each change of post office
address. Any communication, statement or notice addressed to a participant or a
person entitled to benefits at his last post office address as shown on the
employers' records will be binding on the participant and any person entitled to
benefits for all purposes of the plan. None of the employers or the plan
administrator are required to search for or locate any participant or other
person entitled to benefits under the plan. If the plan administrator notifies a
participant or any other person that he is entitled to a distribution and also
notifies him of the provisions of this section, and the participant or person
entitled to benefits fails to claim his benefits under the plan or make his
whereabouts known to the plan administrator within five years after the
notification, the benefits under the plan of the participant or other person may
be disposed of, to the extent permitted by federal law, as follows:

                           (a) If the whereabouts of the participant is unknown
                  and the whereabouts of a person entitled to receive the
                  participant's benefits under the plan then is known to the
                  plan administrator, distribution may be made to such other
                  person.

                           (b) If the whereabouts of the participant and any
                  person entitled to his benefits then is unknown to the plan
                  administrator, but the whereabouts of one or more relatives by
                  blood, adoption or marriage of the participant is known to the
                  plan administrator, distribution may be made to any one or
                  more of such relatives and in such proportions as the plan
                  administrator determines.

                  7.12 PAYMENT WITH RESPECT TO INCAPACITATED PARTICIPANTS OR
BENEFICIARIES. If any person entitled to benefits under the plan is under a
legal disability or, in the plan administrator's opinion, is incapacitated in
any way so as to be unable to manage his financial affairs, the plan
administrator may direct the payment of such benefits to such person's legal
representative or to a relative or friend of such person for such person's
benefit, or the plan administrator may direct the application of such benefit
for the benefit of such person in any manner which the plan administrator may
select that is permitted by federal law and is consistent with the plan. Any

payments made in accordance with the foregoing provisions of this section shall
be a full and complete discharge of any liability for such payments.

                                    ---------

                                  REEMPLOYMENT
                                  ------------

                  8.1 REHIRED EMPLOYEE. If a former employee of a Penton Company
who had not previously become a participant in the plan is reemployed by an
employer and becomes a covered employee before his retirement date, the
following provisions shall apply in his case, notwithstanding any other
provisions of the plan:

                           (a) If he is reemployed by a Penton Company before he
                  has incurred a one-year break in service (as defined in
                  subsection 8.3), his employment with the employers shall be
                  deemed to have continued without interruption for purposes of
                  determining his eligibility to become a participant and his
                  years of service and he shall become a participant during his
                  period of reemployment when he meets the eligibility
                  requirements of section 2.1.

                           (b) If he is reemployed by a Penton Company after he
                  has incurred a one-year break in service, he will become a
                  participant immediately following the twelve consecutive month
                  period commencing on the date of his reemployment, provided he
                  meets all of the eligibility requirements of section 2.1.

                           (c) If he is reemployed by a Penton Company after he
                  has incurred a one-year break in service and if he becomes a
                  participant in the plan pursuant to subsection (b) next above,
                  then:

                                    (i) If subparagraph (ii) next below does not
                           apply in his case, his prior years of service shall
                           be added to his years of service earned after his
                           reemployment.

                                    (ii) If at the time of his prior termination
                           of employment with the employers he had no vested
                           interest in the plan and if he incurred five
                           consecutive one-year breaks in service, his prior
                           years of service shall not be reinstated and shall be
                           disregarded for purposes of the plan.

                  8.2 REHIRED PARTICIPANT. If a former participant or a
participant whose employment with the employers had terminated but who has not
received all benefits due him under the plan is reemployed by a Penton Company
but he does not again become a covered employee before his retirement date,
payment of his benefits, if any, shall be suspended for each



                                     - 27 -




<PAGE>   35





calendar month within the period of his reemployment during which he receives
compensation for at least 40 hours of service, but shall be resumed when such
period of reemployment ends. However, if his death occurs during the period of
his reemployment and if immediately prior to his reemployment his benefits were
being paid in the form of the qualified joint survivor annuity described in
subsection 7.1(a), in the form of a joint and survivor annuity described in
subsection 7.2(b), in the form of a period certain option described in
subsection 7.2(a), or in the full cash refund form described in subsection
7.2(e) benefits that would have been payable under the plan to his spouse under
the qualified joint and survivor annuity or to his spouse or any other person he
had designated under the joint and survivor annuity option, the period certain
option, or the full cash refund option, whichever applies, if he had not been
reemployed and his benefits had not been suspended shall become payable under
the plan. If a former participant, or a participant whose employment with the
Penton Companies had terminated but who has not received all benefits due him
under the plan, is reemployed by a Penton Company and again becomes a
participant before his retirement date, payment of his benefits, if any, shall
be suspended for each calendar month which commences during the period of his
reemployment. The following provisions shall apply in the case of such a
participant or former participant, notwithstanding any other provisions of the
plan:

                           (a) He shall become an active participant on the date
                  he again becomes a covered employee of an employer.

                           (b) If he is reemployed and becomes an active
                  participant before he has incurred a one-year break in
                  service, his prior years of service shall be added to his
                  years of service earned after his reemployment and his prior
                  years of service shall be added to his years of service earned
                  after his reemployment.

                           (c) If he is reemployed and becomes an active
                  participant after he has incurred a one-year break in service,
                  his prior years of service shall be added to his years of
                  service earned after his reemployment, except as follows:

                                    (i) If at the time of his prior termination
                           of employment with the employers he had less than
                           five years of service and thus was not entitled to a
                           monthly retirement income or deferred vested benefit
                           at the time of his prior termination of employment,
                           and if his break in service period exceeds his prior
                           years of service, his prior years of service shall
                           not be reinstated and shall be disregarded for
                           purposes of the plan; and

<PAGE>   36




                                    (ii) If subparagraph (i) above does not
                           apply in his case but as a result of his prior
                           termination of employment he has received his entire
                           benefit due under the plan in the form of a lump sum
                           payment, his prior years of service shall not be
                           reinstated and shall be disregarded for purposes of
                           the plan.

                  8.3 ONE-YEAR BREAK IN SERVICE, FIVE-YEAR BREAK IN SERVICE,
BREAK-IN SERVICE PERIOD. For purposes of the plan, a "one-year break in service"
means any plan year in which a terminated employee or participant does not
complete more than 500 hours of service. A "five-year break in service" means a
period of five consecutive one-year breaks in service. A "break-in service
period" means the total number of an employee's or participant's consecutive
one-year breaks in service after his employment termination or retirement date.

                  8.4 REDETERMINATION OF BENEFITS. If a former employee who is
reemployed by a Penton Company and who had previously participated in the plan
again becomes an active participant in accordance with subsection 8.2(a), no
benefits shall be payable to him under the plan during the period of his
reemployment if he was not receiving benefits at the time of his reemployment
and, if he was receiving benefits at the time of his reemployment, payment of
his benefits shall be suspended for any calendar month within the period of his
reemployment during which he receives compensation for at least 40 hours of
service. Benefits payable to or with respect to a participant under the plan
after his period of reemployment ends shall be redetermined in accordance with
the provisions of the plan as then in effect. However, if the years of service
he was entitled to at the time of his initial termination of employment have
been added to the years of service earned after his reemployment pursuant to
section 8.2, such benefits shall be reduced by the actuarial equivalent of the
benefits, if any, previously paid to him under the plan. In no event shall his
redetermined benefits be less than the benefits he was receiving or entitled to
receive under the plan immediately prior to his reemployment.

                                ----------------
                  9.1 BENEFIT LIMITATIONS. Section 415 of the Code imposes
certain limitations on the amount of benefits that may be provided for a
participant under a defined benefit plan (as 



                                     - 29 -

defined in section 414(j) of the Code) maintained by his employer. If a
participant in a defined benefit plan maintained by his employer also is a
participant in a defined contribution plan (as defined in section 414(i) of the
Code) maintained by his employer, section 415 imposes certain combined
limitations as to the amount of benefits that may be provided for the
participant under both types of plans. This plan is a defined benefit plan and,
therefore, each participant in the plan shall be subject to the maximum benefit
limitations set forth in section 9.3 or 9.4, whichever applies, irrespective of
any other provisions of the plan. For purposes of section 415 of the Code, the
employers' "limitation year" is the plan year.

                  9.2 TOTAL COMPENSATION. For purposes of this Article 9, a
participant's "total compensation" means, with respect to any plan year, the
total compensation paid to the participant during that year for services
rendered to the Penton Companies as an employee that is subject to withholding
for federal income tax purposes (before taking into account any withholding
exemptions) and amounts contributed by an employee pursuant to a salary
reduction agreement as defined in section 414(s)(3) of the Code, but excluding
any noncash compensation and any compensation deferred beyond the participant's
retirement date or employment termination date.

                  9.3 PARTICIPANT COVERED BY DEFINED BENEFIT PLAN. If a
participant in the plan is not covered by a defined contribution plan maintained
by the employers, the participant's monthly retirement income or deferred vested
benefit payable under the plan (disregarding for this purpose that portion of
any joint and survivor annuity which constitutes a qualified joint and survivor
annuity under section 417(b) of the Code) may not exceed an amount that is
actuarially equivalent to a monthly benefit, commencing for life only, equal to
the lesser of (1) $7,500 (or such other maximum amount effective no sooner than
January 1 of any plan year as may be permitted from time to time by the
Secretary of the Treasury or his delegate or by law) (the "$7,500 limitation")
or (2) 1/12 of 100 percent of the participant's average annual total
compensation during that period of three consecutive plan years during which he
actively participated in the plan and in which his aggregate total compensation
was the greatest (or during his entire period of participation if less than
three such years). The foregoing limitation is subject to the following:

                           (a) ADJUSTMENT OF LIMITATION FOR YEARS OF
                  PARTICIPATION OR SERVICE. In the case of a participant with
                  less than ten years of

                  participation, the limitation described in (1) of the first
                  sentence of this section shall be multiplied by a fraction,
                  the numerator of which shall be the participant's number of
                  years (or part thereof) of participation in the plan, and the
                  denominator of which shall be ten. In the case of a
                  participant with less than ten years of service the
                  limitations described in (2) of the first sentence of this
                  section and section 415(b)(4) of the Code shall be multiplied
                  by a fraction, the numerator of which shall be the
                  participant's number of years of service (or part thereof),
                  and the denominator of which shall be ten. In no event shall
                  the adjustments provided in this subsection (a) reduce the
                  limitations described in subsection (1) of the first sentence
                  of this section and section 415(b)(4) of the Code to an amount
                  less than one-tenth of the applicable limitation (determined
                  without regard to this subsection).

                           (b) ADJUSTMENT OF LIMITATION FOR EARLY OR DEFERRED
                  RETIREMENT. If the benefit payable under the plan to a
                  participant commences after his attainment of the Social
                  Security retirement age, the limitation described in (1) of
                  the first sentence of this section shall be adjusted in
                  accordance with Treasury regulations so that it equals the
                  actuarial equivalent of the maximum benefit payable at the
                  Social Security retirement age, based on an interest rate
                  assumption of five percent (5%) per year. If the benefit
                  payable under the plan to a participant commences prior to his
                  attainment of the Social Security retirement age, the
                  limitation described in (1) of the first sentence of this
                  section shall be adjusted in accordance with Treasury
                  regulations so that it equals the actuarial equivalent of such
                  benefit commencing at the Social Security retirement age. The
                  adjustment provided in the preceding sentence shall be made in
                  such manner as the Secretary of the Treasury may prescribe
                  which is consistent with the reduction for old-age insurance
                  benefits commencing before the Social Security retirement age
                  under the Social Security Act.

                           (c) SOCIAL SECURITY RETIREMENT AGE DEFINED. The term
                  "Social Security retirement age" shall mean the age used as
                  the retirement age for the participant under section 216(1) of
                  the Social Security Act, except that such section shall be
                  applied without regard to the age increase factor, and as if
                  the early retirement age under section 216(1)(2) of such Act
                  were 62.

                           (d) PRESERVATION OF CURRENT ACCRUED BENEFIT. If the
                  current accrued benefit of an employee who is a participant as
                  of the effective date exceeds the limitations of section 415
                  of the Code (as modified by paragraphs (b) and (c) of this
                  section), then, for purposes of sections 415(b) and 415(e) of
                  the Code, the defined benefit dollar limitation with respect
                  to such participant shall be equal to his current accrued
                  benefit. The term "current accrued benefit" means a
                  participant's accrued benefit under the plan, determined as if
                  the participant had 

                                     - 31 -

                  separated from service on December 31, 1988, when expressed as
                  an annual benefit within the meaning of section 415(b)(2) of
                  the Code (without regard to any cost of living adjustment
                  occurring after May 5, 1986).

                  9.4 PARTICIPANT COVERED BY DEFINED BENEFIT PLAN AND DEFINED
CONTRIBUTION PLAN. Effective prior to January 1, 2000, if a participant in the
plan also is a participant in a defined contribution plan maintained by the
employers, the benefit payable to the participant under this plan and the
contributions made on behalf of the participant under such defined contribution
plan shall be determined in a manner consistent with section 415 of the Code, as
follows:
                           (a) A fraction shall be determined which will equal
                  the benefits accrued or payable to or for such participant
                  under the plan as of the end of the plan year divided by the
                  "defined benefit limitation amount" in effect for that year.
                  The "defined benefit limitation amount" for any plan year
                  shall be the lesser of (i) 1.25 multiplied by the dollar
                  limitation in effect under section 415(b)(1)(A) of the Code
                  for such year, provided that in any year in which the plan
                  would be a "top-heavy" plan if 90 percent were substituted for
                  60 percent in subsection 17.1(b), 1.0 shall be substituted for
                  1.25, or (ii) 1.4 multiplied by 100 percent of the
                  participant's average annual total compensation for the three
                  consecutive plan years during which he actively participated
                  in the plan and in which his aggregate total compensation was
                  the greatest; provided that such amount shall be appropriately
                  adjusted if necessary as provided in section 415(b) of the
                  Code.

                           (b) A fraction shall also be determined indicating
                  the ratio of the participant's annual additions (as defined in
                  section 415(c)(2) of the Code) under the defined contribution
                  plans of the employers for each plan year to the aggregate of
                  the "defined contribution limitation amount" in effect for
                  each year of the participant's employment by the employers.
                  The "defined contribution limitation amount," for any year
                  shall be the lesser of (i) 1.25 multiplied by the dollar
                  limitation in effect under section 415(c)(1)(A) of the Code
                  for such year, provided that in any year in which the plan
                  would be a top-heavy plan if 90 percent were substituted for
                  60 percent in subsection 17.1(b), 1.0 shall be substituted for
                  1.25, or (ii) 1.4 multiplied by 25 percent of the
                  participant's total compensation for such year.

                           (c) The benefits under this plan shall be reduced
                  (before any reductions are made in contributions under the
                  defined contribution plans of the employers) so that the sum
                  of the fractions determined with respect to any participant in
                  accordance with subsections 9.4(a) and (b) above will

                  not exceed 1.0 (or such other applicable maximum amount
                  permitted by law).

                  9.5 COMBINING OF PLANS. In applying the limitations set forth
in sections 9.3 and 9.4 reference to the plan shall mean the plan and all other
defined benefit plans (whether or not terminated) maintained by the employers,
reference to a defined contribution plan maintained by the employers shall mean
that plan and all other defined contribution plans (whether or not terminated)
maintained by the employers.

                  10.1 PLAN ADMINISTRATOR'S DUTIES. As provided in section 1.2,
a committee appointed by the company is responsible for the administration of
the plan. Except as otherwise specifically provided and in addition to the
powers, rights and duties specifically given to the plan administrator elsewhere
in the plan, the plan administrator shall have the following powers, rights and
duties:

                           (a) To construe and interpret the plan, to decide all
                  questions of plan eligibility, to determine the amount, manner
                  and time of payment of any benefits under the plan, to make
                  findings of fact and to remedy ambiguities, inconsistencies or
                  omissions.


                           (b) To adopt such rules of procedure as may be
                  necessary for the efficient administration of the plan and as
                  are consistent with the plan, and to enforce the plan in
                  accordance with its terms and such rules.

                           (c) To make determinations as to the right of any
                  person to a benefit, to afford any person dissatisfied with
                  such determination the right to a hearing thereon, and to
                  direct payments or distributions from the trust in accordance
                  with the provisions of the plan.

                           (d) To furnish the employers with such information as
                  may be required by them for tax or other purposes in
                  connection with the plan.

                           (f) To employ agents, attorneys, accountants,
                  actuaries or other persons (who also may be employed by the
                  employers, the trustees, or any investment manager or
                  managers) and to allocate or delegate to them such powers,
                  rights and duties as the plan administrator considers
                  necessary or advisable to properly carry out the
                  administration of the plan (including but not limited to the
                  preparation of recommendations of actuarial assumptions which
                  shall be reviewed by the plan administrator), provided that
                  any such allocation or delegation and the acceptance thereof
                  must be in writing.

                           (g) To report to the directors of the company or to
                  such person or persons as the directors of the company
                  designate as to the administration of the plan, any
                  significant problems which have developed in connection with
                  the administration of the plan and any recommendations which
                  the plan administrator may have as to the amendment of the
                  plan or the modification of plan administration.

                  10.2 ACTION BY PLAN ADMINISTRATOR. During a period in which
two or more plan administrative committee members are acting, any action by the
plan administrator will be subject to the following provisions:

                           (a) The committee may act by meeting (including a
                  meeting from different locations by telephone conference) or
                  by document signed without meeting, and documents may be
                  signed through the use of a single document or concurrent
                  documents.

                           (b) A committee member by writing may delegate part
                  or all of his rights, powers, duties and discretions to any
                  other committee member, with such other committee member's
                  consent.

                           (c) The committee shall act by a majority decision,
                  which action shall be as effective as if such action had been
                  taken by all members of the committee; provided that by
                  majority action one or more committee members or other persons
                  may be authorized to act with respect to particular matters on
                  behalf of all committee members.

                           (d) If there is an equal division among the committee
                  members with respect to any questions, a disinterested party
                  may be selected by a majority vote to decide the matter. Any
                  decision by such disinterested party will be binding.

                           (e) The certificate of the secretary of the committee
                  or the majority of the committee members that the committee
                  has taken or authorized any action shall be conclusive in
                  favor of any person relying on such certificate.

                           (f) Except as required by law, no member of the
                  committee shall be liable or responsible for an act or
                  omission of other committee members in which the former has
                  not concurred.

                  10.3 INFORMATION REQUIRED FOR PLAN ADMINISTRATION. The
employers shall furnish the plan administrator with such data and information as
the plan administrator considers necessary or desirable to perform its duties
with respect to plan administration. The records of an employer as to an
employee's or participant's period or periods of employment, termination of
employment and the reason therefor, leaves of absence, reemployment, and
compensation will be conclusive on all persons unless determined to the plan
administrator's satisfaction to be incorrect. Participants and other persons
entitled to benefits under the plan also shall furnish the plan administrator
with such evidence, data or information as the plan administrator considers
necessary or desirable for the plan administrator to perform his duties with
respect to plan administration.

                  10.4 DECISION OF PLAN ADMINISTRATOR FINAL. Subject to
applicable law and the provision of section 10.5, any interpretation of the
provisions of the plan and any decision on any matter within the discretion of
the plan administrator made by the plan administrator in good faith shall be
binding on all persons. A misstatement or other mistake of fact shall be
corrected when it becomes known, and the plan administrator shall make such
adjustment on account thereof as the plan administrator considers equitable and
practicable.

                  10.5 REVIEW OF BENEFIT DETERMINATIONS. If a claim for benefits
made by a participant or his beneficiary is denied, the plan administrator
shall, within 90 days (or 180 days if special circumstances require an extension
of time) after the claim is made, furnish the person making the claim with a
written notice specifying the reasons for the denial. Such notice shall also
refer to the pertinent plan provisions on which the denial is based, describe
any additional material or information necessary for properly completing the
claim and explain why such material or information is necessary, and explain the
plan's claim review procedures. If requested in writing, the plan administrator
shall afford each claimant whose claim has been denied a full and fair review of
the plan administrator's decision and, within 60 days (120 days if special
circumstances require additional time) of the request for reconsideration of the
denied claim, the plan administrator shall notify the claimant in writing of the
plan administrator's final decision.

                  10.6 UNIFORM RULES. The plan administrator shall perform his
duties with respect to plan administration on a reasonable and nondiscriminatory
basis and shall apply uniform rules to all participants similarly situated.

                  10.7 PLAN ADMINISTRATOR'S EXPENSES. All costs, charges and
expenses reasonably incurred by the plan administrator will be paid by the plan
to the extent not paid by the employers in such portions as the company shall
direct; provided no compensation will be paid to a committee member as such.

                  10.8 INTERESTED PLAN ADMINISTRATOR. If a member of the plan
committee is also a participant in the plan, he may not decide or determine any
matter or question concerning his benefits unless such decision or determination
could be made by him under the plan if he were not a committee member.

                  10.9 RESIGNATION OR REMOVAL OF PLAN ADMINISTRATIVE COMMITTEE
MEMBERS. A member of the committee may be removed by the company at any time by
ten days' prior notice to him and the other members of the committee. A member
of the committee may resign at any time by giving ten days' prior written notice
to the company and the other members of the committee. The company may fill any
vacancy in the membership of the committee; provided, however, that if a vacancy
reduces the membership of the committee to less than three, such vacancy shall
be filled as soon as practicable. The company shall give prompt written notice
thereof to the other members of the committee. Until any such vacancy is filled,
the remaining members may exercise all of the powers, rights and duties
conferred on the plan administrator.

                  10.10 INDEMNIFICATION. To the extent permitted by law, no
person (including a trustee, any present or former plan administrative committee
member, and any present or former director, officer or employee of any employer)
shall be personally liable for any act done or omitted to be done in good faith
in the administration of the plan or the investment of the pension fund. To the
extent permitted by law, each present or former director, officer or employee of
any employer to whom the plan administrator or an employer has delegated any
portion of its responsibilities under the plan and each present or former plan
administrative committee member shall be indemnified and saved harmless by the
employers (to the extent not indemnified or saved harmless under any liability
insurance or other indemnification arrangement with respect to the


                                     - 36 -

plan) from and against any and all claims of liability to which they are
subjected by reason of any act done or omitted to be done in good faith in
connection with the administration of the plan or the investment of the trust
fund, including all expenses reasonably incurred in their defense if the
employers fail to provide such defense.

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

                  11.1 ACTION BY EMPLOYERS. Any action required or permitted of
an employer under the plan shall be by resolution of its board of directors or
by a duly authorized committee of its board of directors, or by a person or
persons authorized by resolution of its board of directors or such committee.

                  11.2 ADDITIONAL EMPLOYERS. Any subsidiary or other related
company that is not an employer may adopt the plan and become an employer
thereunder by filing with the trustees and the plan administrator a certified
copy of a resolution of the board of directors of the subsidiary or other
related company providing for its adoption of the plan and a certified copy of a
resolution of the directors of the company consenting to such adoption.

                  11.3 RESTRICTIONS ON REVERSIONS. The employers shall have no
right, title or interest in the assets of the plan, nor will any part of the
assets of the plan at any time revert or be repaid to an employer, directly or
indirectly, except as follows:

                           (a) If the Internal Revenue Service initially
                  determines that the plan, as applied to any employer, does not
                  meet the requirements of a "qualified plan" under section
                  401(a) of the Code, the assets of the plan attributable to
                  contributions made by that employer under the plan shall be
                  returned to that employer within one year of the date of
                  denial of qualification of the plan as applied to that
                  employer.

                           (b) If a contribution or a portion of a contribution
                  is made by an employer as a result of a mistake of fact, such
                  contribution or portion of a contribution shall not be
                  considered to have been contributed under the plan by that
                  employer and, after having been reduced by any losses of the
                  trust fund allocable thereto, shall be returned to that
                  employer within one year of the date the amount is contributed
                  under the plan.

                           (c) Each contribution made by an employer is
                  conditioned upon the deductibility of such contribution as an
                  expense for federal income tax purposes and, therefore, to the
                  extent that a contribution is made by an employer under the
                  plan for a period for which the deduction for a contribution
                  made by the employer is disallowed, then such contribution or
                  portion of a contribution, after having been reduced by any
                  losses of the pension fund allocable thereto, shall be
                  returned to that employer within one year of the date of
                  disallowance of the deduction.

                           (d) If after all fixed and contingent liabilities or
                  obligations to persons entitled to benefits under the plan
                  shall have been paid or provided for in full any plan assets
                  remain because of erroneous actuarial computation, such assets
                  shall be returned to the company.

                      AMENDMENT, TERMINATION OR PLAN MERGER
                      -------------------------------------

                  12.1 AMENDMENT. While the employers expect and intend to
continue the plan, the company must necessarily reserve and hereby does reserve
the right, subject to section 11.3, to amend the plan from time to time, except
as follows:

                           (a) The duties and liabilities of the plan
                  administrator cannot be changed substantially without the
                  consent of the plan administrator; and

                           (b) No amendment shall reduce the value of a
                  participant's benefits to less than the amount he would be
                  entitled to receive if he had resigned from the employ of all
                  of the employers on the day of the amendment.

The foregoing provisions of this section shall be subject to any applicable
collective bargaining agreements, provided that the company may amend the plan
at any time to the extent necessary in order that the plan shall meet the
requirements of a "qualified plan" under section 401(a) of the Code and any
other requirements of applicable law.

                  12.2 TERMINATION. The plan will terminate as to all employers
on any date specified by the company, and as to any employer on any date
specified by the that employer, if 10 days' advance written notice of the
termination is given to the plan administrator and any other employers. The plan
will terminate as to an individual employer on the first to occur of the
following:

                           (a) The date that employer is judicially declared
                  bankrupt or insolvent.

                           (b) The dissolution, merger, consolidation or
                  reorganization of that employer, or the sale by that employer
                  of all or substantially all of its assets, except that:

                                    (i) In any such event arrangements may be
                           made with the consent of the company whereby the plan
                           will be continued by any successor to that employer
                           or any purchaser of all or substantially all of its
                           assets without a termination thereof, in which case
                           the successor or purchaser will be substituted for
                           that employer under the plan; and

                                    (ii) If any employer is merged, dissolved or
                           in any way reorganized into, or consolidated with,
                           any other employer, the plan as applied to the former
                           employer will automatically continue in effect
                           without a termination thereof.

Notwithstanding the foregoing, if any of the events described above should occur
but some or all of the participants employed by an employer are transferred to
employment with one or more of the other employers coincident with or
immediately after the occurrence of such event, the plan as applied to those
participants will automatically continue in effect without a termination
thereof. The foregoing provisions of this section shall be subject to any
applicable collective bargaining agreements.

                  12.3 PLAN MERGER. In no event shall there be any merger or
consolidation of the plan with, or transfer of assets or liabilities to, any
other plan unless each participant in the plan would (if the plan then
terminated) received a benefit immediately after the merger, consolidation or
transfer which is equal to or greater than the benefit the participant would
have been entitled to receive immediately before the merger, consolidation or
transfer (if the plan had then terminated).

                  12.4 CONTINUATION BY A SUCCESSOR OR PURCHASER. Notwithstanding
section 12.2, the plan and the trust shall not terminate in the event of
dissolution, merger, consolidation or reorganization of an employer or sale by
an employer of its entire assets or substantially all of its
assets if arrangements are made in writing between the employer and any
successor to the employer or purchaser of all or substantially all of its assets
whereby such successor or purchaser will continue the plan and the trust. If
such arrangements are made, then such successor or purchaser shall be
substituted for the employer under the plan and the trust agreement.

                  12.5 NOTICE TO PARTICIPANTS OF AMENDMENTS, TERMINATIONS OR
PLAN MERGERS. Participants affected thereby shall be notified by the company
within a reasonable time following any amendment, termination, plan merger, or
consolidation.
                  12.6 VESTING AND DISTRIBUTION ON TERMINATION. On termination
or partial termination of the plan as respects all employers (and, at the
discretion of the company, on a termination or partial termination of the plan
as respects any employer that does not result in the termination or partial
termination of the plan as respects all employers), the rights of all affected
employees to benefits accrued to the date of such termination shall be
nonforfeitable, but in such event such affected employees and other participants
and other persons entitled to benefits under the plan who are affected by such
event shall have no recourse towards the satisfaction of their nonforfeitable
benefits from other than the assets allocable to them under Article 14 or the
PBGC. Notwithstanding the above, the benefits provided upon plan termination to
any highly compensated employee (or any highly compensated former employee)
shall be limited to a benefit that is nondiscriminatory within the meaning of
section 401(a)(4) of the Code. For purposes of this Article 12, whether an
employee is highly compensated will be determined in accordance with section
414(q) of the Code and regulations thereunder.

                            FUNDING OF PLAN BENEFITS
                            ------------------------

                  13.1 EMPLOYER CONTRIBUTIONS. Subject to the provisions of
Article 14, the employers expect and intend to make contributions under the plan
from time to time of such amounts as are required under accepted actuarial
principles to maintain the plan in a sound condition and to meet all applicable
funding requirements imposed by federal law. The method of valuation used to
calculate the cost of the plan for purposes of this section and the actuarial
assumptions applied in regard to such method of valuation shall be determined
from time to time by the company, subject to applicable law.

                  13.2 PENSION FUND. A "pension fund" will be maintained in
order to implement and carry out the provisions of the plan and to fund benefits
payable under the plan. The pension fund from time to time shall consist of one
or more funds established through one or more 



                                     - 40 -




<PAGE>   48


insurance contracts or trust agreements, or through a combination of insurance
contracts and trust agreements, as determined by the company. Such fund or funds
shall be maintained for the purposes of receiving and holding contributions to
the plan and interest and other income thereon and paying benefits provided
under the plan. The company shall determine the form and terms of each insurance
contract and trust agreement and from time to time may direct the transfer of
amounts held in any such fund to any other such fund in accordance with the
provisions of the applicable trust agreements or insurance contracts. Subject to
applicable law, benefits provided through any insurance contract will be paid in
accordance with its terms and conditions.

                  13.3 APPLICATION OF FORFEITED BENEFITS. Benefits that would
have been payable to a participant if his employment with the employers had not
terminated before he was eligible to receive a monthly retirement income or
deferred vested benefits, and benefits that would have been payable to the
participant or any other person but for the participant's death, shall not be
applied to increase the benefits of any other participants or other persons.
However, the limitation contained in the next preceding sentence shall not in
any way limit the right reserved to the company under section 12.1 to amend the
plan to provide for increases or decreases in the amount of benefits or to
modify the form of any benefits payable under the plan.

                   ALLOCATION AND DISTRIBUTION ON TERMINATION
                   ------------------------------------------

                  On termination or partial termination of the plan as respects
all employers (and, at the discretion of the company, on a termination or
partial termination of the plan as respects any employer that does not result in
the termination or partial termination of the plan as respects all employers),
the plan administrator will direct the allocation and distribution of plan
assets allocable to participants employed by that employer with respect to whom
the plan is terminated, to retired or terminated participants, and to spouses
and other persons entitled to benefits under the plan as joint annuitants, to
the extent their benefits are attributable to employment with that employer.
After payment of any expenses of administration and liquidation allocable to
such plan assets, such plan assets remaining shall be allocated and distributed
to such participants and other persons to provide their benefits accrued to the
date of plan termination, to the extent of the



                                     - 41 -

sufficiency of the plan assets, in accordance with the provisions of section
4044 of the Employee Retirement Income Security Act of 1974, as amended
("ERISA").

                            RESTRICTIONS ON BENEFITS
                            ------------------------

                  15.1 PRE-TERMINATION RESTRICTIONS. In the event of the
termination of the plan, as provided in section 12.2, the benefit of any
highly-compensated employee (and any highly compensated former employee) will be
limited to a benefit that is nondiscriminatory under section 401(a)(4) of the
Code. For purposes of this Article 15, whether an employee is highly compensated
will be determined in accordance with section 414(q) of the Code and regulations
thereunder.

                  15.2 RESTRICTION OF BENEFITS. Annual payments to a "restricted
employee" are restricted to an amount equal in each year to the payments that
would be made on behalf of the employee under (i) a straight life annuity that
is the actuarial equivalent of the accrued benefit and other benefits to which
the employee is entitled under the plan (other than a Social Security
supplement), and (ii) the amount of the payments that the employee is entitled
to receive under a Social Security supplement; provided, however, that the
foregoing restrictions on annual payments to a restricted employee shall not
apply if any one of the following requirements is satisfied:

                           (a) The value of plan assets remaining after payment
                  of all benefits payable to the restricted employee equals or
                  exceeds 110 percent of the value of current liabilities, as
                  defined in section 412(l)(7) of the Code;

                           (b) The value of the benefits payable to the
                  restricted employee from the plan is less than one percent of
                  the value of current liabilities of the plan as determined
                  before distribution to such restricted employee; or

                           (c) The value of the benefits payable to the
                  restricted employee from the plan does not exceed the amount
                  described in section 411(a)(11)(A) of the Code.

For purposes of this Article 15, a "restricted employee" is an employee who is a
highly compensated employee or highly compensated former employee; provided
that, in any plan year,


                                     - 42 -




<PAGE>   50



no more than 25 employees will be restricted employees, and those employees who
are restricted employees will be those highly compensated employees and highly
compensated former employees with the greatest compensation in the current or
any prior plan year. The value of benefits payable to a restricted employee and
the current liabilities of the plan shall be determined in accordance with
Treasury Regulation section 1.401(a)(4)-5 or any substitute therefor.

                               GENERAL PROVISIONS
                               ------------------

                  16.1 EXAMINATION OF PLAN DOCUMENTS. Copies of the plan and any
amendments thereto will be on file at the principal office of each employer
where they may be examined by any participant or any other person entitled to
benefits under the plan.

                  16.2 NOTICES. A notice mailed to a participant or beneficiary
at his last address filed with the plan administrator in care of the company
will be binding on the participant or beneficiary for all purposes of the plan.
Any notice or document relating to the plan required to be given to or filed
with the plan administrator or any employer shall be considered as given or
filed if delivered or mailed by registered or certified mail, postage prepaid,
to the plan administrator, in care of Penton Media, Inc., 1100 Superior Avenue,
Cleveland, Ohio 44114.

                  16.3 NONALIENATION OF PLAN BENEFITS. The rights or interests
of any participant or any participant's beneficiaries to any benefits or future
payments hereunder shall not be subject to attachment or garnishment or other
legal process by any creditor of any such participant or beneficiary, nor shall
any such participant or beneficiary have any right to alienate, anticipate,
commute, pledge, encumber or assign any of the benefits or rights which he may
expect to receive, contingently or otherwise under this plan except as may be
required by the tax withholding provisions of the Code or of a state's income
tax act or pursuant to a qualified domestic relations order, as defined in
section 414(p) of the Code.

                  16.4 NO EMPLOYMENT GUARANTEE. None of the establishment of the
plan, modification thereof, the creation of any fund or account, or the payment
of any benefits shall be construed as giving to any participant or other person
any legal or equitable right against the employers, the plan administrator or
any trustee except as herein provided. Under no


                                     - 43 -

circumstances shall the terms of employment of any participant be modified or in
any way affected hereby. The maintenance of this plan shall not constitute a
contract of employment, and participation in the plan will not give any
participant a right to be retained in the employ of the employers. None of the
employers, the plan administrator or the trustees in any way guarantees any
assets of the plan from loss or depreciation or any payment to any person. The
liability of the plan administrator or any employer as to any payment or
distribution of benefits under the plan is limited to the available assets of
the trust fund.

                  16.5 PARTICIPANT LITIGATION. In any action or proceeding
regarding the plan assets (or any property constituting a portion or all
thereof), any plan benefit, or regarding the administration of the plan,
employees or former employees of the employers or their beneficiaries or any
other persons having or claiming to have an interest in this plan shall not be
necessary parties and shall not be entitled to any notice or process. Any final
judgment which is not appealed or appealable and may be entered in any such
action or proceeding shall be binding and conclusive on the parties hereto and
all persons having or claiming to have any interest in this plan. To the extent
permitted by law, if a legal action is begun against the employers, the plan
administrator or the trustees by or on behalf of any person, and such action
results adversely to such person, or if a legal action arises because of
conflicting claims to a participant's or other person's benefits, the costs to
the employers, the plan administrator or the trustees of defending the action
will be charged to the sums, if any, which were involved in the action or were
payable to the participant or other person concerned. To the extent permitted by
applicable law, acceptance of participation in this plan shall constitute a
release of the employers, the plan administrator and the trustees and their
agents from any and all liability and obligation not involving willful
misconduct or gross neglect. Notwithstanding any other provisions of the plan,
if the plan administrator is required by a final court order to distribute the
benefits of a participant other than in a manner required under the plan, then
the plan administrator shall cause the participant's benefits to be distributed
in a manner consistent with such final court order. The plan administrator shall
not be required to comply with the requirements of a final court order in an
action in which the plan administrator, the trustees, the plan or the trust was
not a party, except to 


                                     - 44 -




<PAGE>   52



the extent that such final court order is qualified domestic relations order (as
defined in section 414(p) of the Code).

                  16.6 ACTUARIAL EQUIVALENT. A benefit shall be actuarially
equivalent to any other benefit if the actuarial reserve required to provide the
same is equal to the actuarial reserve required to provide such other benefit,
computed on the basis of the actuarial rates, tables and procedures adopted by
the company for this purpose as reflected in Supplement B which is attached to
and forms a part of the plan. No adjustment to a determination of an actuarially
equivalent value or amount shall be made solely because such tables, rates and
procedures are changed subsequent to a determination. If the actuarial rates or
factors applicable under the plan to the calculation of benefits in the joint
and survivor form or any optional form of payment are changed, the plan
administrator shall thereafter maintain a record of each participant's accrued
benefit as of the date of such change and the amount of such joint and survivor
or any such optional form of payment to which such participant was eligible
immediately prior to such change. Thereafter, if such participant's benefits are
payable in the joint and survivor or in any such optional form, then such
benefits shall not be less than the benefits to which the participant would have
been entitled had the participant terminated employment on the date of such
change and received his benefits in such form.

                  16.7 SUCCESSORS. The plan and the trust will be binding on all
persons entitled to benefits hereunder and their respective heirs and legal
representatives, and on the plan administrator and the trustees and their
successors.

                  16.8 ADEQUACY OF EVIDENCE. Evidence which is required of
anyone under the plan shall be executed or presented by the proper individuals
or parties and may be in the form of certificates, affidavits, documents or
other information which the plan administrator, the trustees, the employers or
other persons acting on such evidence considers pertinent and reliable.

                  16.9 GENDER AND NUMBER. Words denoting the masculine gender
shall include the feminine and neuter genders and the singular shall include the
plural and the plural shall include the singular wherever required by the
context.

                  16.10 WAIVER OF NOTICE. Any notice required under the plan may
be waived by the person entitled to notice.

                  16.11 APPLICABLE LAW. The plan and the trust shall be
construed in accordance with the provisions of ERISA and other applicable
federal laws. To the extent not inconsistent with such laws, this plan shall be
construed in accordance with the laws of the state of Ohio.

                  16.12 SEVERABILITY. If any provision of the plan shall be held
illegal or invalid for any reasons such illegal or invalid provision shall not
affect the remaining provisions of the plan, and the plan shall be construed and
enforced as if such illegal or invalid provisions had never been contained in
the plan.

                  16.13 FIDUCIARY RESPONSIBILITIES. It is specifically intended
that all provisions of the plan shall be applied so that all fiduciaries with
respect to the plan shall be required to meet the prudence and other
requirements and responsibilities of applicable law to the extent such
requirements of responsibilities apply to them. No provisions of the plan are
intended to relieve a fiduciary from any responsibility, obligation, duty or
liability imposed by applicable law. In general, a fiduciary shall discharge his
duties with respect to the plan solely in the interests of participants and
other persons entitled to benefits under the plan and with the care, skill,
prudence, and diligence under the circumstances then prevailing that a prudent
man acting in a like capacity and familiar with such matters would use in the
conduct of an enterprise of like character and with like aims.

                  17.1 TOP-HEAVY PLAN DETERMINATION. For purposes of determining
whether the plan is "top-heavy" for any plan year, the following shall apply:

                           (a) KEY EMPLOYEES. An employee or former employee
                  shall be a "key employee" for any plan year if during such
                  plan year or during any of the four preceding plan years he
                  is:

                                    (i) An officer of his employer whose
                           compensation exceeds 50 percent of the dollar limit
                           as defined in section 415(b)(1)(A) of the Code; or

                                    (ii) One of the ten employees of his
                           employer having annual compensation from his employer

                           the Code and owning (or considered as owning within
                           the meaning of section 318 of the Code) the largest
                           interests in the employer; or

                                    (iii) Any person who owns (or is considered
                           as owning within the meaning of section 318 of the
                           Code) more than five percent of the outstanding stock
                           of an employer or stock possessing more than five
                           percent of the total combined voting power of all of
                           an employer's stock (a "five-percent owner"); or

                                    (iv) Any person having annual compensation
                           in excess of $150,000 who owns (or is considered as
                           owning within the meaning of section 318 of the Code)
                           more than one percent of the outstanding stock of an
                           employer or stock possessing more than one percent of
                           the total combined voting power of all of an
                           employer's stock.

                  For purposes of subparagraph (i) above, if the number of
                  officers exceeds 50, only the 50 officers with the highest
                  compensation shall be considered key employees; and if the
                  number of officers is less than 50, the number of officers
                  considered key employees shall not exceed the greater of
                  three, or ten percent of all employees. For purposes of
                  subparagraphs (iii) and (iv) above, section 318(a)(2)(C) of
                  the Code shall be applied by substituting "five percent" for
                  the reference to "50 percent" therein and the rules of section
                  414(b), (c) and (m) of the Code shall not apply for
                  determining ownership in the employer. In addition, the
                  beneficiary of a key employee shall be deemed to be a key
                  employee. A "non-key employee" is any person who is not a key
                  employee or a beneficiary of such person, including any
                  employee who is a former key employee.

                           (b) TOP HEAVY PLAN. The plan will be considered a
                  "top-heavy plan" for any plan year if, as of the last day of
                  the preceding plan year, (the last day of the initial plan
                  year, in case of that year) (the "determination date") the sum
                  of (i) the aggregate of the accounts of all key employees
                  under all defined contribution plans in an aggregation group
                  of plans as described in subsection (c) below and (ii) the
                  present value of the aggregate accrued benefits for key
                  employees under the plan and all other defined benefit plan in
                  an aggregation group of plans exceeds 60 percent of such sum
                  determined for all participants under all such plans,
                  excluding participants who are former key employees. There
                  shall be included in the determination of a participant's
                  accounts and accrued benefit under such plans any amounts
                  distributed to him during the preceding five-year period.
                  However, a rollover contribution initiated by a participant
                  and made after December 31, 1983 to any plan in an aggregation
                  group of plans shall not be taken into account for purposes of
                  determining whether the plan is a top-heavy plan.
                  Notwithstanding the foregoing, if an individual has not been
                  an employee of the employers at any time during the five-year
                  period ending on the last day of the 



                                     - 47 -




<PAGE>   55





                  preceding plan year, any account balance or accrued benefits
                  of such individual shall be excluded from the determination
                  made under this subsection.

                           (c) AGGREGATION GROUPS. For purposes of this
                  subsection and Article 9, all Penton Companies shall be
                  included in the term "employer." All employer plans in a
                  required aggregation group of plans shall be considered to be
                  top-heavy plans if either the required or permissible
                  aggregation group of plans is determined to be top-heavy under
                  subsection (b) above. If the required or permissive
                  aggregation group of plans is not a top-heavy group, no
                  employer plans in the group shall be considered to be
                  top-heavy plans. A "required aggregation group of plans" shall
                  include each employer plan (whether or not terminated) in
                  which a key employee participates and any other employer plan
                  which enables any plan in which a key employee participates to
                  meet the coverage and nondiscrimination requirements of
                  sections 401(a)(4) or 410 of the Code. A "permissive
                  aggregation group of plans" shall include all plans in the
                  required aggregation group plus any other employer plans which
                  satisfy the requirements of sections 401(a)(4) and 410 of the
                  Code when considered together with the required aggregation
                  group of plans.

                  17.2 SPECIAL TOP-HEAVY PLAN VESTING SCHEDULE. Notwithstanding
the foregoing provisions, a participant who is employed by an employer when the
plan is considered a "top-heavy plan" (as defined in subsection 17.1(b)) shall
be eligible to receive the portion of his benefit commencing on his normal
retirement date equal to the vested percentage determined in accordance with the
following schedule based on the participant's years of service:


                  If the Participant's               His Vested and
                  Number of Years of                 Nonforfeitable
                  Service Equals:                    Interest Shall Be:
                  ---------------                    ------------------

                  Less than 1                                  0%
                  1 but less than 2                           20%
                  2 but less than 3                           40%
                  3 but less than 4                           60%
                  4 but less than 5                           80%
                  5 or more                                  100%

If the plan becomes a top-heavy plan and subsequently ceases to be a top-heavy
plan, the retirement benefits of a participant who has previously become vested
under this special vesting schedule shall again be his benefit calculated under
section 5.1; provided, however:
                           (a) A participant with less than five years of
                  service on the date the plan ceases to be a top-heavy plan
                  shall retain his vested interest as determined under the
                  special vesting schedule in his accrued retirement benefit as
                  of such date.

<PAGE>   56

                           (b) A participant with five or more years of service
                  on the date the plan ceases to be a top-heavy plan shall be
                  entitled to continue under the special vesting schedule if, at
                  termination of employment, it would produce a larger deferred
                  vested benefit for such participant.

                  17.3 TOP-HEAVY MINIMUM BENEFITS. Notwithstanding the
provisions of Article 5 and this Article 17, a participant's normal or deferred
retirement benefit (or, if applicable, his monthly deferred vested benefit
commencing on his normal retirement date) shall not be less than an amount equal
to 3.0 percent of his final average earnings (as defined below) multiplied by
the aggregate of his number of years of service (not in excess of 10 such years)
in all plan years for which the plan is considered a top-heavy plan. For this
purpose, a participant's "final average earnings" shall be the monthly average
of the total earnings (including bonuses) paid to the participant during the
five consecutive calendar year period for which his earnings were highest within
his period of employment as a covered employee.

                  Executed as of this 7th day of August, 1998.

                       PENTON MEDIA, INC. RETIREMENT PLAN


                  B-1 PURPOSE, USE OF TERMS. The purpose of this Supplement B is
to set forth the actuarial assumptions referred to in section 16.6 of the plan.
Except where the context indicates to the contrary, terms used and defined in
the plan shall have the same respective meanings for purposes of this
Supplement.
                  B-2 ACTUARIAL ASSUMPTIONS. Until the actuarial assumptions are
modified by the company, actuarial equivalence shall be determined during any
plan year on the basis of the 1971 Group Annuity Mortality Table for Males set
back one year of age for participants and five years of age for beneficiaries
under the qualified joint and survivor and optional joint and survivor forms of
benefit and a 6 percent interest rate assumption. In addition, for purposes of
computing the lump sum actuarially equivalent value of the monthly benefit
payable (or with respect to) to a participant, the lump sum actuarially
equivalent value shall be determined by using an interest rate equal to 7
percent. Notwithstanding anything in this Supplement B or the plan to the
contrary, in no event will the lump sum actuarially equivalent value of a
monthly benefit payable to (or with respect to) a participant be less than the
greatest of (a) the lump sum actuarially equivalent value determined using the
interest rate which would be used (as of the calendar month in which the date of
the distribution occurs) by the PBGC for purposes of determining the lump sum
actuarially equivalent value of a lump sum distribution on plan termination, or
(b) the lump sum actuarially equivalent value of the participant's accrued
benefit, if any, under the plan as of December 31, 1986, determined using a 6
percent interest rate assumption.

                                  INTRODUCTION
                                  ------------

1.1 THE PLAN AND ITS EFFECTIVE DATE. This Penton Media, Inc. Supplemental
Executive Retirement Plan (the "plan") has been established by Penton Media,
Inc. (the "company"), effective August 7, 1998 (the "effective date").

1.2 PURPOSE. The company maintains the Penton Media, Inc. Retirement Plan (as
the same may hereafter be amended, the "retirement plan"), which is intended to
meet the requirements of a "qualified plan" under the Internal Revenue Code of
1986, as amended (the "Code"). While the Code places limitations on the maximum
benefits which may be paid from a qualified plan and the maximum amount of an
employee's compensation that may be taken into account for determining benefits
payable under a qualified plan, the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), permits the payment under an "unfunded plan" of
benefits which may not be paid under a qualified plan because of such
limitations. The purpose of the plan is to provide certain key employees of the
company and its subsidiaries with certain benefits which may not be provided
under the retirement plan because of the maximum compensation limitation of the
Code.

                                   SECTION 2
                                   ---------
                                        
                            ELIGIBILITY AND BENEFITS
                            ------------------------

2.1 ELIGIBILITY. Each key employee of the company or a subsidiary of the company
(a "participant") who participates in the retirement plan and who is a party to
an employment agreement with the company or a subsidiary of the company
substantially in the form attached hereto as Exhibit 1 (as the same may
hereafter be amended, his "Employment Agreement") that provides for his
participation in the plan or in the Pittway Corporation Supplemental Executive
Retirement Plan shall participate in the plan, subject to the conditions and
limitations of the plan. It is expressly understood that variations among the
participants' Employment Agreements may result in differences in the numbered
paragraphs thereof in which corresponding provisions appear (for example, the
non-competition provisions which are in paragraph 10 of Exhibit 1 attached
hereto, or variations thereof, may be in paragraph 10 of certain of the
Employment Agreements but in paragraph 9 of others). Accordingly, each reference
in the plan to a particular numbered paragraph of a participant's Employment
Agreement shall be deemed to be a reference to the paragraph thereof, if any,
which corresponds to the identically numbered paragraph of Exhibit 1.

2.2 ACCRUED BENEFIT. For 1995 and for each full calendar year and any final
fraction of a calendar year of a participant's Employment Period (as such term
is defined in such participant's Employment Agreement), the participant shall
accrue a benefit under the plan equal to 1.85 percent of that portion of his
earnings (as defined in section 2.3 below) for such year or fraction that is in
excess of the "maximum dollar limitation" (as defined below) for such year or
fraction and is less than $300,000. 



                                      - 1 -

<PAGE>   2



For purposes of the plan, "maximum dollar limitation" means, for
any year or fraction of a year, the greater of $150,000 or the dollar amount of
any higher maximum limitation on annual compensation taken into account under a
qualified plan for such year or fraction of a year determined by the Secretary
of Treasury or his delegate or by law under section 401(a) (17) of the Code; it
being understood that annual compensation for purposes of such limitation is
computed differently from "earnings" for purposes of the plan. A participant's
accrued benefits under the plan shall be referred to hereinafter as the
participant's "supplemental retirement benefits."

2.3 EARNINGS. For purposes of the plan, a participant's "earnings" for any year
or fraction means his total, regular cash compensation paid for such year or
fraction for services rendered to any Penton Company (as such term is defined in
the retirement plan) or, prior to the effective date, to the Pittway Companies
(as such term is defined in the Pittway Corporation Retirement Plan) during such
year or fraction, consisting solely of his salary and his annual discretionary
cash bonus, if any, for such year. It is expressly understood that a
participant's "earnings" do not include any other compensation, including,
without limitation, any of the following:

         (a)      Long-term incentive compensation;

         (b)      Unused vacation pay;

         (c)      Special cash bonuses;

         (d)      Any income realized for Federal income tax purposes as a
                  result of the grant or exercise of an option or options to
                  acquire shares of common stock of a Pittway Company or the
                  company, the receipt or exercise of any stock appreciation
                  right or payment, or the disposition of shares acquired by the
                  exercise of such an option or right;

         (e)      Any noncash compensation, including any amounts contributed by
                  the participant's employer(s) for his benefit under the
                  retirement plan or any other retirement or benefit plan,
                  arrangement, or policy maintained by his employer(s);

         (f)      Any reimbursements for medical, dental or travel expenses,
                  automobile allowances, relocation allowances, educational
                  assistance allowances, awards and other special allowances;

         (g)      Any income realized for Federal income tax purpose as a result
                  of (i) group life insurance, (ii) the personal use of an
                  employer-owned automobile, or (iii) the transfer of restricted
                  shares of stock or restricted property of a Pittway Company or
                  the company, or the removal of any such restrictions;

         (h)      Any severance pay paid as a result of the participant's
                  termination of employment (it being expressly understood that
                  any amount(s) taken into account pursuant to the final
                  sentence of section 2.8 below shall not be deemed severance
                  pay for purposes hereof); or

         (i)      Any compensation paid or payable to the participant, or to any
                  governmental body or agency on account of the participant,
                  under the terms of any state, Federal or foreign



                                      - 2 -

                  law requiring the payment of such compensation because
                  of the participant's voluntary or involuntary termination of
                  employment with the company .

Notwithstanding the foregoing, a participant's "earnings" do include (i) any
salary reduction amount elected by the participant and credited to a cafeteria
plan (as defined in section 125(c) of the Code) or a qualified cash or deferred
arrangement (as defined in section 401(k) of the Code) and (ii) the initial
value ascribed to any performance shares award the participant elects to receive
in lieu of a portion of his annual discretionary cash bonus.

2.4 PAYMENT OF BENEFITS. Each participant's Employment Agreement provides that
in no event shall his Employment Period be extended beyond his 65th birthday
except by mutual agreement of the participant and his employer. Subject to the
conditions and limitations of the plan, upon a participant's attainment of age
65 years, he shall be entitled to a monthly benefit payable for his life
commencing upon his attainment of age 65 years in an amount equal to one-twelfth
(1/12) of the sum of the participant's accrued supplemental retirement benefits.
A participant's supplemental retirement benefits shall be paid to him in the
form described below that applies to the participant; provided, however, that in
lieu of payment in the normal form described below, the participant may
irrevocably elect, within thirty (30) days after his commencement of
participation in the plan, to receive his supplemental retirement benefits in a
single lump sum as soon as practicable after his attainment of age 65 years. A
participant's "supplemental retirement benefit commencement date" means the date
as of which the initial payment (or, in the case of a single lump sum, full
payment) of the supplemental retirement benefits to which the participant is
entitled is payable. Subject to the conditions and limitations of the plan, a
participant's supplemental retirement benefit commencement date shall normally
be the first day of the calendar month coincident with or next following the
participant's attainment of age 65 years. Notwithstanding the immediately
preceding sentence, if a participant's Employment Period under his Employment
Agreement terminates prior to his attainment of age 65 years and he is eligible,
and elects, to receive early retirement benefits under the retirement plan, and
if the participant requests a supplemental retirement benefit commencement date
prior to his attainment of age 65 years, then with (but only with) the consent
of the committee (as defined in section 3.1 below), the participant's
supplemental retirement benefit commencement date shall be such earlier date, if
any, selected by the committee. Supplemental retirement benefits that are paid
in a lump sum, or commence, before the participant's attainment of age 65 years,
if any, shall be subject to actuarial reduction in accordance with section 2.5
below.

         (a)      LIFE ANNUITY. If a participant does not have a spouse (as
                  defined in section 2.7 below) on his supplemental retirement
                  benefit commencement date, and if he has not elected pursuant
                  to the preceding provisions of this section 2.4 to receive his
                  supplemental retirement benefits in a single lump sum, payment
                  of his supplemental retirement benefits shall be during his
                  lifetime on a life annuity basis.

         (b)      JOINT AND SURVIVOR ANNUITY. If a participant has a spouse (as
                  defined in section 2.7 below) on his supplemental retirement
                  benefit commencement date, payment of his supplemental
                  retirement benefits shall be in the form of a joint and 50
                  percent survivor annuity unless the participant has
                  theretofore elected pursuant to the preceding provisions of
                  this section 2.4 to have his benefits provided in a single
                  lump sum.

                  Such joint and 50 percent survivor annuity shall consist of a
                  reduced monthly benefit continuing during the participant's
                  lifetime, and if such spouse is living at the time of


                                      -3-
<PAGE>   4


                  the participant's death, payment of 50 percent of such monthly
                  benefit shall be made to such spouse until such spouse's death
                  occurs. The amount of the participant's and such spouse's
                  benefits under this subsection shall be calculated so that it
                  is the actuarial equivalent of the supplemental retirement
                  benefits to which the participant would otherwise be entitled
                  under the plan. If such spouse predeceases the participant, or
                  if the participant and such spouse cease to be married after
                  the participant's supplemental retirement benefit commencement
                  date, there shall be no adjustment to the participant's
                  monthly payments and no supplemental retirement benefits shall
                  be payable to any person after the participant' s death.

2.5 ACTUARIAL EQUIVALENT. A benefit shall be actuarially equivalent to another
benefit if the actuarial reserve required to provide such benefit is equal to
the actuarial reserve required to provide such other benefit, computed on the
basis of the same actuarial assumptions, interest rates, tables, methods and
procedures, including reduction factors for commencement of payments prior to
attainment of age 65 years, that are used for purposes of the retirement plan as
in effect on the applicable date that a benefit payment amount is determined.

2.6 PRE-RETIREMENT SURVIVING SPOUSE BENEFIT. If a participant dies prior to his
supplemental retirement benefit commencement date, no supplemental retirement
benefits under the plan shall be paid or payable with respect to the
participant; provided, however, that if the participant has a spouse (as defined
in section 2.7 below) at the time of his death, such spouse shall be entitled to
receive a monthly benefit for such spouse's lifetime equal to 50 percent of the
amount of monthly benefit that would have been payable to the participant in the
form of a joint and 50 percent survivor annuity if he had terminated employment
as of the date of his death with entitlement to supplemental retirement benefits
under the plan and the committee (as defined in section 3.1 below) had permitted
his supplemental retirement benefit commencement date to occur on the first day
of the calendar month coincident with or next following the date of his death,
taking into account actuarial reduction for commencement prior to the
participant's attainment of age 65 years. The first payment to the spouse shall
be made as of the first day of the calendar month coincident with or next
following the date of the participant's death and the final payment shall be
made as of the first day of the calendar month during which the spouse's death
occurs. If, prior to the participant's death, the participant had elected
pursuant to section 2.4 above to receive his supplemental retirement benefits in
a single lump sum, in lieu of the monthly payments described above, such spouse
shall be entitled to receive a single lump sum equal to 50 percent of the lump
sum value of the participant's supplemental retirement benefits as of the date
of his death, taking into account actuarial factors for payment prior to the
participant's attainment of age 65 years. Such lump sum payment shall be made to
such spouse as soon as practicable following the participant's death.

2.7 SPOUSE. For purposes of the plan, a person will be considered the "spouse"
of a participant as of any date if and only if such person and the participant
have been married in a religious or civil ceremony recognized under the laws of
the state where the marriage was contracted and the marriage remains legally
effective. Any person who is not, or who has ceased to be, a participant's
"spouse" on the participant's supplemental retirement benefit commencement date
(or, in the event of the participant's death prior to his supplemental
retirement benefit commencement date, the date of his death) shall not be
considered the participant's "spouse" for purposes of the plan.

2.8 FORFEITURE; EARLY TERMINATION OF EMPLOYMENT PERIOD. If the participant's
Employment Period ends early pursuant to paragraph 5 of his Employment Agreement
on account of a Termination for

                                      -4-
<PAGE>   5




Cause or a Termination by Executive with Advance Notice (as such terms are
defined, respectively, in his Employment Agreement), or if after the
participant's Employment Period ends (whether or not early and regardless of the
reason) the participant breaches any of his agreements in paragraph 7, 9 or 10
of his Employment Agreement, the participant shall forfeit all of his
supplemental retirement benefits, if any, under the plan, no benefit under the
plan shall thereafter be payable to or with respect to the participant or his
spouse, and any benefit under the plan theretofore paid to or with respect to
the participant or his spouse must be repaid to the company by the participant
or his spouse promptly upon demand. If the participant's Employment Period ends
early pursuant to paragraph 5 of his Employment Agreement on account of a
Termination without Cause or a Termination by Executive for Good Reason (as such
terms are defined, respectively, in his Employment Agreement), the participant's
supplemental retirement benefits under the plan shall be the supplemental
retirement benefits the participant would have been entitled to under the plan
had his Employment Period remained in effect until the earlier of the date on
which (without any extension thereof) such Employment Period was then scheduled
to end pursuant to his Employment Agreement or the date of his death and had the
participant's salary in effect as of the last day of his Employment Period (or,
if greater, his Executive's Reference Salary (as such term is defined in his
Employment Agreement)) continued until the earlier of such dates and been paid
at the times such salary would have been paid, and had the participant received
no further annual cash bonus.

2.9 FUNDING. The plan is intended to be non-qualified for purposes of the Code
and unfunded for purposes of the Code and ERISA. Benefits payable under the plan
to a participant and/or his spouse, as the case may be, shall be paid directly
by the company . The company shall not be required to segregate on its books or
otherwise any amount to be used for payment of supplemental retirement benefits
under the plan. Each participant and spouse is solely an unsecured creditor of
the company with respect to any benefit payable with respect to a participant
hereunder.

Company (but subject to variations among executives resulting from differences

                           equal to Executive's salary; but only if and so long

                           Package or from a comparable insurer acceptable to
                           the Company;

                  (ii)     supplementary long-term disability coverage in an
                           amount which will increase maximum covered annual
                           compensation to $330,000 and the maximum monthly
                           payments to $18,333; but only if and so long as such

                           from the insurer providing long-term disability

                           Package or a comparable insurer acceptable to the
                           Company; and

                  (iii)    participation in the Penton Media, Inc. Supplemental
                           Executive Retirement Plan (the "SERP"), a copy of
                           which, as currently in effect, is attached hereto as
                           Exhibit A.

                  4. ADJUSTMENTS. Notwithstanding any other provision of this
Agreement, it is expressly understood and agreed that if there is a significant
reduction in the level of the business to which Executive's duties under this
Agreement relate, or if all or any significant part of such business is disposed
of by the Company and/or its subsidiaries or affiliates during the Employment
Period but Executive thereafter remains an employee of the Company, the Board
may make adjustments in Executive's duties, responsibility and authority, and in
Executive's compensation, as the Board deems appropriate to reflect such
reduction or disposition.

                  5.       EMPLOYMENT PERIOD.

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

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

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

                           perform his duties hereunder by reason of illness or

                           hundred eighty (180) days prior to the effective date
                           of such termination identifying such termination as a
                           Termination by Executive with Advance Notice
                           ("TERMINATION BY EXECUTIVE WITH ADVANCE NOTICE") (it
                           being expressly understood that Executive's giving
                           notice that the extension provision in the first
                           sentence of paragraph 5(b) hereof shall no longer
                           apply shall not constitute a "TERMINATION BY
                           EXECUTIVE WITH ADVANCE NOTICE").

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

                           or any of its subsidiaries or affiliates;

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

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

                  (vi)     repudiation of this Agreement by Executive or

                           Termination by Executive with Advance Notice shall

                  (vii)    breach by Executive of any of the agreements in
                           paragraph 10 hereof; or

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

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

<PAGE>   12


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

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

                  6.       POST-EMPLOYMENT PERIOD PAYMENTS.

                  (a) If the Employment Period ends on the date on which
(without any extension thereof) it is then scheduled to end pursuant to
paragraph 5 hereof, or if the Employment Period ends early pursuant to paragraph
5 hereof for any reason, Executive shall cease to have any rights to salary,
bonus (if any), or benefits other than: (i) any salary which has accrued but is
unpaid, any reimbursable expenses which have been incurred but are unpaid, and
any unexpired vacation days which have accrued under the Company's vacation
policy but are unused, as of the end of the Employment Period, (ii) (but only to
the extent provided in any option theretofore granted to Executive or in the
SERP or any other benefit plan in which Executive has participated as an
employee of the Company) any option rights or plan benefits which by their terms
extend beyond termination of Executive's employment, (iii) any benefits to which
Executive is entitled under the Consolidated Omnibus Budget Reconciliation Act
of 1985, as amended ("COBRA"), and (iv) any other amounts(s) payable pursuant to
the succeeding provisions of this paragraph 6.

                  (b) If the Employment Period ends pursuant to paragraph 5
hereof on Executive's sixty-fifth birthday, or if the Employment Period ends
early pursuant to paragraph 5 hereof on account of Executive's death, Retirement
or Termination for Disability, the Company shall make no further payments to
Executive except as contemplated in (a) (i), (ii) and (iii) above.

                  (c) If the Employment Period ends early pursuant to paragraph
5 hereof on account of Termination for Cause, the Company shall pay Executive an
amount equal to that Executive would have received as salary (based on
Executive's salary then in effect) had the Employment Period remained in effect
until the later of the effective date of the Company's termination of
Executive's employment or the date thirty days after the Company's notice to
Executive of such termination.

                  (d) If the Employment Period ends early pursuant to paragraph
5 hereof on account of a Termination without Cause or a Termination by Executive
for Good Reason, the Company shall pay to Executive amounts equal to the amounts
Executive would have received as salary (based on Executive's salary then in
effect or, if greater, Executive's Reference Salary) had the Employment Period
remained in effect until the date on which (without any extension thereof) it
was then scheduled to end, at the times such amounts would have been paid (in
the event Executive is entitled during the payment period to any payments under
any disability benefit plan or the like in which Executive has participated as
an employee of the Company, less such payments); PROVIDED, HOWEVER, that in the
event of Executive's death during the payment period, the Company shall pay


                                      -5-
<PAGE>   13



any subsequent such amounts to Executive's estate (or such person or persons as
Executive may designate in a written instrument signed by him and delivered to
the Company prior to his death) either (i) amounts during the remainder of the
payment period equal to one-half of the of the amounts which would have been
paid to Executive but for his death or (ii) if so elected by the payee(s) by
written notice to the Company within the period of sixty (60) days after the
date of Executive's death, a lump sum amount equivalent to the discounted
present value of such reduced amounts, discounted at the publicly announced
reference rate for commercial lending of the Company's principal lending bank in
effect from time to time, in effect at the date of notice to the Company of such
election, with said amount to be paid on a date no later than thirty (30) days
following the date of notice to the Company of such election. In addition, the
Company shall reimburse Executive (net after taxes on the receipt of such
reimbursement) for any premiums paid by Executive for health insurance provided
to Executive (for Executive and his dependents) by the Company subsequent to the
end of the Employment Period pursuant to the requirements of COBRA as in effect
on the date of this Agreement. It is expressly understood that the Company's
payment obligations under this (d) shall cease in the event Executive breaches
any of his agreements in paragraph 7, 9 or 10 hereof.

                  (e) If the Employment Period ends early pursuant to paragraph
5 hereof on account of a Termination by Executive with Advance Notice, the
Company shall make no further payments to Executive except as contemplated in
(a) (i), (ii) and (iii) above.

                  7. INVENTIONS AND OTHER INTELLECTUAL PROPERTY. Executive
agrees that all inventions, innovations, improvements, developments, methods,
designs, analyses, drawings, reports, trademarks, slogans, product or other
designs, advertising or marketing programs, and all similar or related
information which relate to the Company's or any of its subsidiaries' or
affiliates' actual or anticipated business, research and development or existing
or future products or services and which are (or were prior to the date of this
Agreement) conceived, developed or made by Executive, whether alone or jointly
with others, while employed by the Company or any such subsidiary or affiliate
or any predecessor thereof ("WORK PRODUCT") belong to the Company or such
subsidiary or affiliate. Executive will promptly disclose such Work Product to
the President of the Company and perform all actions reasonably requested by the
President of the Company (whether during or after the Employment Period) to
establish and confirm such ownership (including, without limitation,
assignments, consents, powers of attorney and other instruments).

                  8. LIMITATION/ILLINOIS DISCLOSURE. Paragraph 7 of this
Agreement regarding the ownership of inventions and other intellectual property
does not apply to the extent application thereof is prohibited by any law the
benefits of which cannot be waived by Executive. Executive hereby waives the
benefits of any such law to the maximum extent permitted by law. In accordance
with Section 2872 of the Illinois Employee Patent Act, Ill. Rev. Stat. Chap.
140, ss. 301 ET. SEQ. (1983), Executive is hereby advised that in the event and
to the extent such Act is applicable to Executive, paragraph 7 of this Agreement
regarding the ownership of inventions and other intellectual property does not
apply to any invention for which no equipment, supplies, facilities or trade
secret information of the Company or any of its subsidiaries or affiliates was
used and which was developed entirely on Executive's own time, unless (i) the
invention relates to the business of the Company or any of its subsidiaries or
affiliates or to the Company's or any of its subsidiaries' or affiliates' actual
or demonstrably anticipated research or development or (ii) the invention
results from any work performed by Executive for the Company or any of its
subsidiaries or affiliates.

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

                  10.      NON-COMPETE, NON-SOLICITATION.

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

                  (b) Executive agrees (i) that during the Employment Period he
shall not in any manner, directly or indirectly, through any person, firm or
corporation, alone or as a member of a partnership or as an officer, director,
stockholder, investor or employee of or in any other corporation or enterprise
or otherwise, engage or be engaged in, or assist any other person, firm,
corporation or enterprise in engaging or being engaged in, any business then
actively being conducted by the Company or any of its subsidiaries or
affiliates, and (ii) that for two years after the Employment Period he shall not
in any manner, directly or indirectly, through any person, firm or corporation,
alone or as a member of a partnership or as an officer, director, stockholder,
investor or employee of or in any other corporation or enterprise or otherwise,
assist _______________ or any subsidiary or affiliate of _____________, or any
successor or assign of ____________, in engaging or being engaged in the
business activity of publishing a magazine or electronic media product that
directly competes with any magazine or electronic media product then being
published by, conducting a trade show that directly competes with any trade show
then being conducted by, or creating or disseminating any other product that
competes directly with any product then being created or disseminated by, the
Company or any of its subsidiaries or affiliates.

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

<PAGE>   15


                  (d) Nothing in this paragraph 10 shall prohibit Executive from
being: (i) a stockholder in a mutual fund or a diversified investment company or
(ii) a passive owner of not more than 2% of the outstanding stock of any class
of a corporation which is publicly traded, so long as Executive has no active
participation in the business of such corporation.

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

                  11. ENFORCEMENT. Because Executive's services are unique and
because Executive has access to Confidential Information and Work Product, the
parties hereto agree that the Company would be damaged irreparably in the event
any of the provisions of paragraph 7, 9 or 10 hereof were not performed in
accordance with their specific terms or were otherwise breached and that money
damages would be an inadequate remedy for any such non-performance or breach.
Therefore, the Company or its successors or assigns shall be entitled, in
addition to other rights and remedies existing in their favor, to an injunction
or injunctions to prevent any breach or threatened breach of any of such
provisions and to enforce such provisions specifically (without posting a bond
or other security).

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

                  13. SURVIVAL. Paragraphs 7, 9 and 10 hereof shall survive and
continue in full force in accordance with their terms notwithstanding any
termination of the Employment Period.

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

                  Cleveland, Ohio  44114

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

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

                  16. PAYMENT OF CERTAIN COSTS AND EXPENSES. In the event that
there is a Change of Control of the Company, if the Company thereafter
wrongfully withholds from Executive any amount payable to Executive pursuant to
this Agreement or the SERP and Executive obtains a final judgment against the
Company for such amount, the Company shall reimburse Executive for any costs and
expenses (including without limitation attorneys' fees) reasonably incurred by
Executive in obtaining such judgment and shall pay Executive interest on the
amount of each such cost or expense from the date of payment thereof by
Executive to the date of reimbursement by the Company at a floating rate per
annum equal to the publicly announced reference rate for commercial lending, in
effect from time to time, of the Company's principal lending bank in effect from
time to time. For purposes of the foregoing, a "CHANGE OF CONTROL OF THE
COMPANY" will be deemed to have occurred if but only if, for purposes of Section
13(d) of the Securities Exchange Act of 1934, as amended, a person or group
other than (i) Pittway or (ii) one or more members of the Harris Group becomes
the beneficial owner of stock of the Company possessing a majority of the voting
power under ordinary circumstances with respect to the election of directors.
For purposes of the preceding sentence, the "Harris Group" shall mean Messrs.
Irving B. Harris, Neison Harris, King Harris, William W. Harris and Sidney
Barrows, and their respective spouses, descendants and spouses of descendants,
trustees of trusts established for the benefit of such persons (acting in their
capacity as trustees of such trusts), and executors of estates of such persons
(acting in their capacity as executors of such estates), and each person of
which any of the foregoing owns (i) more than fifty percent (50%) of the voting
stock or other voting interests and (ii) stock or other interests
representing more than fifty percent (50%) of the total value of the stock or
other interests of such person.

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

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

                  19. SUCCESSORS AND ASSIGNS. This Agreement shall bind and
inure to the benefit of and be enforceable by Executive, the Company and their
respective heirs, executors, personal representatives, successors and assigns,
except that neither party may assign any of his or its rights or delegate any of
his or its obligations hereunder without the prior written consent of the other
party. Executive hereby consents to the assignment by the Company of all of its
rights and obligations hereunder to: (i) Pittway or any subsidiary or affiliate
thereof in the event all or any substantial part of the business to which
Executive's duties under this Agreement relate are transferred thereto and (ii)
any successor to the Company by merger or consolidation or purchase of all or
substantially all of the Company's assets; in each case provided such transferee
or successor assumes the liabilities of the Company hereunder.

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

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