================================================================================

         This Amendment No. 2 to Schedule 13D (this "STATEMENT") relates to the
common stock, par value $0.01 per share (the "COMMON STOCK"), of Penton Media,
Inc. (the "ISSUER"). This Statement supplementally amends the initial statement
on Schedule 13D, filed on March 19, 2002 (the "INITIAL STATEMENT"), as amended
by Amendment No. 1 to the Initial Statement, filed on August 1, 2006 (the "First
Amendment"), by ABRY Mezzanine Partners, L.P., a Delaware limited partnership,
ABRY Mezzanine Investors, L.P., a Delaware limited partnership, ABRY Mezzanine
Holdings, LLC, a Delaware limited liability company and Royce Yudkoff, an
individual resident of the state of Massachusetts (collectively, the "REPORTING
PERSONS").

ITEM 4. PURPOSE OF TRANSACTIONS.

         Item 4 is hereby amended by adding the following:

         On November 1, 2006, the Issuer entered into an Agreement and Plan of
Merger (the "Prism Merger Agreement") with Prism Business Media Holdings, Inc.,
a Delaware corporation ("Parent"), and Prism Acquisition Co., a Delaware
corporation and a direct wholly-owned subsidiary of Parent ("Merger
Subsidiary"). Pursuant to the Prism Merger Agreement, (i) Merger Subsidiary will
merge with and into the Issuer (the "Prism Merger"), (ii) the separate corporate
existence of Merger Sub shall cease and the Issuer shall continue its corporate
existence under Delaware law as the surviving corporation (the "Surviving
Corporation") and shall become a wholly-owned subsidiary of Parent, (iii) each
share of Common Stock, par value $0.01 per share, of the Issuer ("Issuer Common
Stock") issued and outstanding, other than any shares of Issuer Common Stock
owned by the Issuer or any of its wholly-owned subsidiaries, by Parent or any of
its wholly-owned subsidiaries or by dissenting stockholders that properly
exercise appraisal rights, or Issuer Common Stock to be cancelled, shall be
converted into the right to receive the Common Stock Per Share Merger
Consideration, as defined in the Prism Merger Agreement, (iv) each share of
Series C Preferred Stock, par value $0.01 per share, of the Issuer (the "Series
C Preferred Stock") issued and outstanding, other than any shares of Series C
Preferred Stock owned by the Issuer or any of its wholly-owned subsidiaries, by
Parent or any of its wholly-owned subsidiaries or by dissenting stockholders
that properly exercise appraisal rights, or Series C Preferred Stock to be
cancelled, shall be converted into the right to receive an amount in cash,
without interest, equal to the Series C Preferred Stock Per Share Merger
Consideration, as defined in the Prism Merger Agreement, (v) each share of
Series M Preferred Stock, par value $0.01 per share, of the Issuer (the "Series
M Preferred Stock") issued and outstanding, other than any shares of Series M
Preferred Stock owned by the Issuer or any of its wholly-owned subsidiaries, by
Parent or any of its wholly-owned subsidiaries or by dissenting stockholders
that properly exercise appraisal rights, or Series M Preferred Stock to be
cancelled, shall be converted into the right to receive an amount in cash,
without interest, equal to the Series M Preferred Stock Per Share Merger
Consideration, as defined in the Prism Merger Agreement.

         As a condition to the willingness of Parent and Merger Subsidiary to
enter into the Prism Merger Agreement, Parent and Merger Subsidiary required
ABRY Mezzanine Partners, L.P., ABACUS Fund Partners, LP, ABACUS Fund, Ltd.,
Sandler Capital Partners V Germany, L.P., Sandler Capital Partners V FTE, L.P.
and Sandler Capital Partners V, L.P. (each individually a "Stockholder", and
collectively the "Stockholders") to enter into a voting agreement (the "Voting
Agreement").

         Pursuant to the Voting Agreement, the Stockholders agreed to vote (or
cause to be voted) all shares of Issuer capital stock held by them and any
shares of Issuer capital stock that may be acquired after the date of the Voting
Agreement (the "Covered Shares") in favor of the Prism Merger, the Prism Merger
Agreement and the transactions contemplated by the Prism Merger Agreement and
against any extraordinary corporate transaction, other than the Prism Merger,
such as a merger, consolidation,


                                       6


business combination, tender or exchange offer, reorganization,
recapitalization, liquidation, sale or transfer of all or substantially all of
the assets or securities of the Issuer and any of is subsidiaries, other than
pursuant to the Prism Merger, or any other acquisition proposal.

         As part of the Voting Agreement, the Stockholders entered into an
irrevocable proxy appointing Parent and certain of its officers or designees as
the sole and exclusive attorneys and proxies of each Stockholder to vote and
exercise all voting and related rights with respect to all of the shares of
Issuer capital stock that now are or hereafter may be beneficially owned by the
Stockholders.

         Pursuant to the Voting Agreement, the Stockholders are prohibited from
transferring any shares of Issuer capital stock.

         The Voting Agreement and the irrevocable proxies will expire upon the
earliest to occur of (i) the effective time of the Prism Merger, (ii) the date
on which the Prism Merger Agreement is terminated pursuant to its terms (iii)
April 30, 2007 and (iv) written notice of termination of the Voting Agreement by
Parent to the Stockholders.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

         Item 5 is hereby amended by adding the following thereto:

         By virtue of the Voting Agreement, the Reporting Persons may be deemed
to share dispositive power and voting power of the Issuer Common Stock held by
them with Parent and Merger Sub.

         The numbers of shares and percentages reported on the cover pages of
this Second Amendment have not been updated since September 30, 2006 to give
effect to the accrual of additional dividends on the Series C Preferred Stock,
the numbers do reflect the accrual of additional dividends on the Series C
Preferred Stock up through September 30, 2006. As dividends on the Series C
Preferred Stock accrue but are not paid, the actual number of shares of Issuer
Common Stock into which the Series C Preferred Stock is convertible and the
voting power of the Issuer represented by such shares, will increase
accordingly.

         Each of the Reporting Persons expressly disclaims beneficial ownership
of any Issuer Common Stock held by any other person to the extent that the
Reporting Person does not hold a pecuniary interest therein.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER.

         The responses to Item 4 of this Amendment and the Exhibit to this
Amendment are incorporated herein by this reference.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.

         Item 7 is hereby amended by adding the following thereto:

         Exhibit 10:  Voting Agreement, dated as of November 1, 2006, by and
                      among ABRY Mezzanine Partners, L.P., ABACUS Fund Partners,

                      Delaware corporation and wholly-owned subsidiary of Parent
                      (incorporated by reference to Exhibit 99.1 to the Current
                      Report on Form 8-K of Penton Media, Inc. filed with the
                      Securities and Exchange Commission on November 2, 2006).
