Notes to Editors:

CMP MEDIA LLC

CMP Media LLC (www.cmp.com) is a leading integrated media company providing
essential information and marketing services to the entire technology spectrum
-- the builders, sellers and users of technology worldwide. Capitalising on its
editorial strength, CMP is uniquely positioned to offer marketers
comprehensive, integrated media solutions tailored to meet their individual
needs. Its diverse products and services include newspapers, magazines,
Internet products, research, direct marketing services, education and training,
trade shows and conferences, and custom publishing.

BASIS OF COMPILATION OF STATISTICS

The statistics, which are the main subject of today's release, are
independently compiled by IMS/Auditor. The basis of compilation includes:

  * pages are hand counted and verified by the publishers
   
  * regional ads are counted if in over 50% of circulation
   
  * house ads are not counted
   
  * inserts are counted if bound in publication
   
  * the database will continually be updated as more accurate information
    arrives
   
All CMP High Tech publications are tracked. CMP determines the competitive set
of publishing titles which are measured on its behalf by IMS Auditor and
periodically adjusts the population to ensure that it is properly
representative of the changing US business technology advertising market in
which CMP competes.

Note: that these statistics represent only total advertising page volumes as
counted above, they do not represent paid advertising page volumes nor do they
show the revenue yields which the operators in these market segments have
achieved.

This press release includes statements which are not historical facts and are
considered "forward-looking" within the meaning of Section 27 of the Securities
Act of 1933, as amended. These forward-looking statements reflect UBM's current
views about future events, business and growth strategy and financial
performance. These forward-looking statements are identified by their use of
terms and phrases such as "believe," "expect," "plan," "anticipate," "on
target" and similar expressions identifying forward-looking statements.
Investors should not rely on forward-looking statements because they are
subject to a variety of risks, uncertainties and other factors that could cause
actual results to differ materially from UBM's expectations. UBM expressly does
not undertake any duty to update forward-looking statements. Management does
not attempt to update forecasts unless conditions materially change.
