WHAT:    Wireless Security Panel Discussion and Media Q&A

         The domestic market for wireless data alone is projected to
         generate $13 billion by 2006 (Atlantic-ACM). However, if the
         market is to safely reach its full potential, industry
         leaders must address the security and interoperability
         challenges of the future -- today. Wireless innovation is one
         of this year's special areas of focus at NetWorld+Interop Las
         Vegas 2003, taking place April 27 - May 2, 2003 at the Las
         Vegas Convention Center.

         To support this focus, media are invited to join in the
         wireless security discussion with industry leaders from
         Microsoft, Vivato and Fortress about the issues and
         technology trends surrounding wireless security.

         The discussion panel includes:

             -- Jawad Khaki, Corporate Vice President of Windows
                Networking and Communications Technology, Microsoft
             -- Ken Biba, CEO, Vivato
             -- Janet Kumpu, Chief Operating Officer, Fortress
                Technologies

         The discussion, which will take the form of a 45-minute
         telephone format, will be followed by a fifteen minute Q&A.

WHEN:    The Wireless Security Panel Discussion and Q&A will be
         conducted via conference call on Monday, April 21, 2003 at

Certain matters discussed in this release are "forward-looking statements," including statements about Key3Media's future results, plans and goals and other events which have not yet occurred. These statements are intended to qualify for the safe harbors from liability provided by the Private Securities Litigation Reform Act of 1995. You can find many (but not all) of these statements by looking for words like "will," "may," "believes," "expects," "anticipates," "plans" and "estimates" and for similar expressions. Because forward-looking statements involve risks and uncertainties, there are many factors that could cause Key3Media's actual results to differ materially from those expressed or implied in this release. These include, but are not limited to, economic conditions generally and in the information technology industry in particular; the timing of Key3Media's events and their popularity with exhibitors, sponsors and attendees; technological changes and developments; intellectual property rights; competition; capital expenditures; and factors impacting Key3Media's international operations. In addition, the IT industry has experienced a significant downturn since the middle of 2001 and the terrorist attacks on September 11, 2001 have adversely affected the economy generally and significantly decreased air travel in particular. These developments have and will continue to adversely affect participation and attendance at Key3Media's events, although the Company is not able to quantify or reliably estimate the future impact that these matters may have on its businesses, results of operations or financial condition. The sections entitled "Item 1. Business -- Certain Factors That May Affect our Businesses" and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Annual Report on Form 10-K for the year ended December 31, 2001 filed by Key3Media with the SEC contain important cautionary statements and a discussion of many of the factors that could materially affect the accuracy of Key3Media's forward-looking statements and/or adversely affect its business, results of operations and financial position. These statements and discussions, as well as any others contained in Key3Media's other SEC public filings, are incorporated herein by reference.
