(1)  Pursuant to Rule 416(c) under the Securities Act of 1933, this registration
     statement also covers an indeterminate amount of interests to be offered
     pursuant to the Penton Media, Inc. 401(k) Retirement Plan (As Amended and
     Restated as of January 1, 2001) (the "Plan").

(2)  Also relates to stock purchase rights that are attached to each share of
     common stock of the Registrant in accordance with the Rights Agreement,
     dated as of June 9, 2000 (as amended), between the Registrant and National
     City Bank, as successor rights agent. These rights are not exercisable
     until the occurrence of






     events described in the Rights Agreement, are evidenced by the certificates
     for the common stock, and are transferred solely with the common stock. The
     value attributed to the rights, if any, is reflected in the value of the
     common stock, and, accordingly, no separate fee is paid.

(3)  Pursuant to Rule 457(h) under the Securities Act of 1933, this estimate is
     made solely for the purpose of calculating the amount of the registration
     fee and is based on the average of the high and low prices of the Common
     Shares of the Registrant on the New York Stock Exchange on March 24, 2003.

     Pursuant to General Instruction E to Form S-8, the contents of the
