                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Participants and Administrator of
Penton Media, Inc. 401(k) Retirement Savings Plan

In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Penton Media, Inc. 401(k) Retirement Savings Plan (the "Plan") at
December 31, 2001 and 2000, and the changes in net assets available for benefits
for the year ended December 31, 2001 in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Plan's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of Assets Held
for Investment Purposes is presented for the purpose of additional analysis and
is not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

PENTON MEDIA, INC. 401(K) RETIREMENT SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2001 AND 2000
--------------------------------------------------------------------------------

     1.   PLAN DESCRIPTION

     The following description of the Penton Media, Inc. 401(k) Retirement
     Savings Plan (the "Plan") provides only general information. Participants
     should refer to the Plan document for a more complete description of the
     Plan's provisions.

     GENERAL
     Prior to August 7, 1998, Penton Media, Inc. ("Penton" or "Company") was a
     wholly owned subsidiary of Pittway Corporation ("Pittway"). Pittway
     distributed 100% of Penton's common stock on August 7, 1998, to Pittway's
     shareholders in a tax-free spinoff. On September 1, 1998, the Company
     adopted the Plan, a 401(k) defined contribution plan. Effective January 1,
     2001, the Plan was amended and restated to incorporate various plan
     qualification requirements made by the Uruguay Round Agreements Act (GATT),
     the Taxpayer Relief Act of 1997, the Reemployment Rights Act of 1994
     (USERRA), the Internal Revenue Service Restructuring and Reform Act of 1998
     and the Small Business Job Protection Act of 1996 (SBJPA).

     On March 15, 2000 Penton sold its Direct Mail segment. Pursuant to Section
     401(k)(10) of the Code, employees of the Direct Mail segment were given the
     option to keep their accounts in the Plan, transfer their account balances
     to a qualified IRA, transfer their account balances to a new plan or
     receive a distribution.

     In September 2000, Penton acquired the stock of Duke Communications
     International ("Duke"). Effective February 23, 2001, Duke employees ceased
     participation in the Duke Communications International 401(k) Retirement
     Plan ("the Duke Plan"), the Duke Plan was frozen and Duke employees began
     participation in the Plan. Effective March 7, 2001, the Duke Plan was
     merged into the Plan and the assets from the Duke Communications
     International 401(k) Retirement Plan were transferred to Fidelity.

     The Plan is subject to the provisions of the Employee Retirement Income
     Security Act of 1974 (ERISA). All non-union employees of the Company become
     eligible to participate in the plan on the first day of the month that is
     at least 30 days after the date on which the employee begins employment
     with the Company.

     CONTRIBUTIONS
     Each year, participants may contribute up to 15% of pretax annual
     compensation, as defined in the Plan. Unless waived, 3% of an
     eligible employee's compensation will automatically be deducted and
     contributed to the Plan. The matching percentage contributed by the
     Company is determined by resolution of the Board of Directors of the
     Company, at their discretion. Contributions are subject to certain
     limitations. Prior to January 1, 2002, the matching contribution was equal
     to 50% of the first 6% of the participants' contributions to the Plan.
     Effective January 1, 2002, the Company temporarily suspended the Company
     match.

     The Plan also permits rollover contributions from other qualified
     retirement plans. Rollover contributions are included in participant
     contributions and amounted to $626,384 in 2001.

     PARTICIPANT ACCOUNTS
     Fidelity maintains an individual account for each participant. This account
     is credited with participant contributions, employer matching contributions
     and Plan earnings, as allocated, based upon each participant's election.

     VESTING
     Participants are immediately vested in both employee and the employer
     matching contributions, plus actual earnings thereon.

     INVESTMENT OPTIONS
     Upon enrollment in the Plan, a participant may direct employee and matching
     employer contributions in one quarter percent increments in any of the
     investment options. Two of the investment options are no longer available
     for future investment purposes, as noted in the descriptions which follow.

     Northern Trust is the trustee for the following funds: AptarGroup Inc.
     Stock Fund, Pittway Corporation Stock Fund, and the Penton Media, Inc.
     Stock Fund. Northern Trust reports all activity of these funds to
     Fidelity. Fidelity manages the following remaining funds: Retirement
     Government Money Market Portfolio, Managed Income Portfolio, Growth &
     Income Portfolio, Aggressive Growth Fund, Magellan Fund, Spartan 500 Index
     Fund, Diversified International Fund, Fidelity Mid-Cap Stock Fund, PIMCO

     mutual fund that invests in obligations, issued or guaranteed as to
     principal and interest by the U.S. Government.

     Fidelity Managed Income Portfolio is a stable value fund (common or
     collective trust). It invests primarily in high-quality, short and long
     term insurance company investment contracts (GICs), bank investment
     contracts (BICs), short term money market instruments and "synthetic" GICs
     (debt obligations issued by one institution and insured by another as to
     the payment of principal at maturity).

     Fidelity Growth & Income Portfolio is a growth and income mutual fund,
     which seeks long-term capital growth, current income, and growth of income
     consistent with reasonable investment risk. It invests primarily in U.S.
     and foreign stocks, focusing on those that pay dividends and show potential
     earnings growth. It may also invest in bonds.

     Fidelity Aggressive Growth Fund is a growth mutual fund and invests
     primarily in stocks of small and medium size developing companies that have
     the potential to grow rapidly. Such stocks may be subject to abrupt or
     erratic price changes.

     Fidelity Magellan Fund is a growth mutual fund and seeks long-term capital
     appreciation by investing in the stocks of both well known and lesser known
     companies with potentially above-average growth potential and a
     correspondingly higher level of risk. Securities held by the fund may
     include both foreign and domestic companies.

     Spartan 500 Index Fund is a growth mutual fund and invests primarily in the
     stocks that are included in the Standard & Poor's Composite Index of 500
     stocks and other securities that are based on the value of the index.

     Fidelity Diversified International Fund is a growth mutual fund that
     invests primarily in stocks of companies located outside of the U.S. that
     are included in the Morgan & Stanley EAFE Index (Europe, Australia, Far
     East Index). It seeks stocks of larger companies that are considered
     undervalued in their countries.

     Fidelity Mid-Cap Stock Fund is a long-term growth mutual fund that invests
     primarily in domestic and foreign stocks of companies with medium market
     capitalization.

DECEMBER 31, 2001 AND 2000
--------------------------------------------------------------------------------

     PIMCO Total Return Fund II seeks total fund return with an average
     portfolio duration between three and six years. The fund invests primarily
     in investment grade fixed income securities, which may include U.S.
     government obligations, mortgage and asset backed securities, variable and
     floating debt securities and convertible securities.

     Neuberger Berman Genesis Trust seeks long term capital appreciation. The
     fund primarily invests in common stocks of small companies.

     Morgan Stanley Value Added Equity Fund seeks capital appreciation and
     current income. The fund primarily invests in common stocks listed on the
     S&P 500.

     Fidelity Freedom Funds provides investing opportunities for both short and
     long term goals by allowing investors to choose from the following fund
     options based on the participants' targeted retirement date: Fidelity
     Freedom Income Fund, Fidelity Freedom 2000 Fund, Fidelity Freedom 2010
     Fund, Fidelity Freedom 2020 Fund, Fidelity Freedom 2030 Fund and Fidelity
     Freedom 2040 Fund. The funds invest in a combination of Fidelity equity,
     fixed income and money market funds which are allocated differently based
     on the retirement goal.

     AptarGroup, Inc. Stock Fund is a fund which, under a former plan, invested
     exclusively in shares of AptarGroup, Inc. stock. Any contributions or
     investment gains previously invested in the AptarGroup, Inc. Stock Fund,
     may, at the present time, remain invested in Aptar Stock. These
     contributions or investment gains may be reinvested in another fund. The
     AptarGroup, Inc. Stock Fund is no longer available as an investment option
     for future contributions.

     Pittway Corporation Stock Fund is a fund which, under a former plan,
     invested exclusively in shares of Pittway Corporation Class A stock. Early
     in 2000, Pittway was sold to Honeywell International, Inc ("Honeywell").
     Upon consummation of the transaction, the Pittway Corporation Stock Fund
     was liquidated and participants were given the option to transfer any
     assets held in the Pittway Stock Fund to the other remaining funds. During
     2000 (for the period prior to the sale to Honeywell), the fund was not
     available as an investment option; therefore, any contributions or
     investment gains previously invested in the fund remained invested in
     Pittway stock.

     Penton Media, Inc. Stock Fund invests exclusively in shares of Penton
     Media, Inc. stock. Investment gains may result from both dividends and
     increases in the market value of shares. Shares in the Penton Media, Inc.
     Stock Fund are acquired on the open market at fair market value on the date
     purchased.

     PARTICIPANT LOANS
     Participants may borrow from their fund accounts a minimum of $1,000 not to
     exceed the lesser of $10,000 or 50% of the account balance. Loan repayments
     are treated as a transfer to the investment funds from the Loan Fund.
     Participant loans are reflected as a transfer from the respective
     investment funds to the Loan Fund. Loan terms may not exceed five years.
     The loans are secured by the balance in the participant's vested account
     and carry an interest rate equal to the prime rate plus one percent on the
     date of the loan. Interest rates range from 6.00% to 11.50%. Principal and
     interest are paid ratably through payroll deductions.

     PAYMENT OF BENEFITS AND WITHDRAWALS
     A participant may withdraw their account balance upon termination of
     employment or upon reaching age 59 1/2 by calling Fidelity directly.

     Hardship withdrawals are available if requirements are met as outlined in
     the plan document.

     Upon termination of employment or death, the accumulated benefits will be
     paid to the participant or beneficiary based on their payment election.
     Participants may elect to receive either a lump sum, a series of
     installments over a period of time as determined by the plan document, or a
     combination of the two.

     2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF ACCOUNTING
     The financial statements of the Plan have been prepared on the accrual
     basis of accounting in accordance with accounting principles generally
     accepted in the United States of America ("GAAP").

     The Plan presents in the statement of changes in net assets available for
     benefits the net appreciation or depreciation in the fair value of its

3.   RISKS AND UNCERTAINTIES

     The Plan provides for various investment options in any combination of
     stocks, bonds, fixed income securities, mutual funds, and other investment
     securities. Investment securities are exposed to various risks, such as
     interest rate, market and credit. Due to the level of risk associated with
     certain investment securities and the level of uncertainty related to
     changes in the value of investment securities, it is at least reasonably
     possible that changes in risks in the near term would materially affect
     participants' account balances and the amounts reported in the Statement of
     Net Assets Available for Benefits and the Statement of Changes in Net
     Assets Available for Benefits.

4.   PARTY-IN-INTEREST TRANSACTIONS

     Party-in-interest transactions consist of loans made to participants,
     investments in the Fidelity Funds and investments in the Penton Media, Inc.
     Stock Fund, Pittway Corporation Stock Fund, and AptarGroup, Inc. Stock
     Fund.

5.   PLAN TERMINATION

     Although it has not expressed any intent to do so, the Company has the
     right under the Plan to amend or terminate the Plan subject to the
     provisions of ERISA. The Company also has the right under the Plan to
     discontinue its contributions at anytime. As mentioned previously in Note
     1, Contributions, effective January 1, 2002, the Company temporarily
     suspended the 50% Company match of the first 6% of each participant's
     contribution.

7.   FEDERAL INCOME TAX STATUS

     The Plan filed for a determination letter from the Internal Revenue Service
     on December 20, 2001 with respect to its qualified status under Section
     401(a) of the Code. The application for a determination letter was filed
     within the remedial amendment period which extended the determination
     letter filing deadline until February 28, 2002. Prior to this filing, the
     Plan did not have a favorable determination letter. However, since the Plan
     was spun-off from the Pittway 401(k) plan in the same form, and Pittway
     received a favorable determination letter dated May 22, 1995, the plan
     administrator believes that the Plan is designed and is currently being
     operated in compliance with the applicable requirements of the Code. As
     such, the Plan financial statements do not reflect any accruals for federal
     and state taxes.
