    PRODUCT LINE OVERVIEW

    o PUBLISHING

         o     Q2 revenues declined $1.5m, or 4%, compared with 2Q 2004.
               Revenues declined $1.0m, or 2.7% after adjusting for
               discontinuations of two print properties and publishing schedule
               changes.

         o     YTD revenues declined $2.3m, or 3.3%; revenues declined $2.0m, or
               2.9% after adjusting for factors noted above.

    o EVENTS

         o     Q2 revenues declined $1.3m, or 26%, primarily due to the
               discontinuation of two events and the timing change of three
               conferences. Revenues grew $1.3m, or 56.7%, adjusting for these
               factors.

         o     YTD revenues declined $0.6m, or 2.8%, due primarily to the change
               in timing of a conference from June in 2004 to September this
               year. Revenues increased $1.6m or 8.4%, after adjusting for the
               timing change and event discontinuations.

    o ONLINE

         o     Q2 revenues grew $0.4m, or 10%, due primarily to new product
               successes across several business units. Adjusting for
               discontinued properties, revenues expanded $0.5m, or 12.2%.

         o     YTD eMedia revenues increased $1.1m, or 14.3%. Adjusting for
               discontinued properties, revenues increased $1.4m or 19.2%.

         o     New Web conferences and product introductions are expected to
               accelerate our eMedia growth rate to high teens in Q3 and Q4.

REPORTING SEGMENT OVERVIEW

    o INDUSTRY

         o     Q2 revenues expanded $0.6m, or 2.8%, to $20.0m on the strength of
               eMedia increases across the four market units that comprise the
               segment. After adjusting for a conference timing shift, revenues
               were up $0.8m, or 4.2%.

         o     YTD revenues grew $0.8m, or 2.1%, to $37.5m. After adjusting for
               the event timing change noted, revenues grew $1.0m, or 2.9%.

    o TECHNOLOGY

         o     Q2 revenues declined $1.3m or 7.7%. The decline was due largely
               to shift in timing of two IT conferences, roadshow timing and
               weakness in electronics OEM print advertising. IT media print
               advertising strengthened with a more modest revenue decline
               year-to-year. Adjusting for discontinued properties and timing of
               events, revenues were flat with the year-ago period.

         o     YTD revenues down $1.9m, or 6.2%. Adjusting for discontinued
               properties, revenues were down $0.8, or 2.7%.




    o LIFESTYLE

         o     Q2 revenues down $1.0m, or 24.9%, due largely to discontinuation
               of Natural Products Expo Europe, which took place in Q2 of 2004.
               Adjusting for that factor, segment revenues increased modestly.

         o     YTD revenues down $0.3m, or 1.3%. Adjusting for the discontinued
               event, revenues increased $0.8m, or 3.8%.

    o RETAIL

         o     Q2 revenues were down $0.6m, or 9.8%, due primarily to publishing
               schedule changes and a discontinued conference. Revenues
               decreased $0.1m, or 2%, after adjusting for these factors.

         o     YTD revenues decreased $0.4m, or 3.6%. Adjusting for timing
               differences and cancelled products, revenues were flat to the
               year-ago period.

STRATEGIC REVIEW

    o Significant progress made with strategies to drive revenue and profits by
      accelerating eMedia product development and serving customers' marketing
      needs through integrated media solutions that leverage the strength of our
      leading magazine brands. The Company also is pursuing selected strategic
      investments in add-on properties and strategic partnerships that enhance
      our current product offering. Recent strategic highlights include:

         o     125 Web conferences produced in the first half of 2005 compared
               with 100 in the first half of 2004;

         o     25 digital editions developed YTD, including 2 digital-only
               editions creating growth opportunities in targeted markets;

         o     8 Web sites and 3 new microsites were launched or redeveloped in
               first half of 2005;

         o     Acquisition in June of Kosher World trade show, to collocate with
               Natural Products Expo West in March 2006, providing foundation
               for expansion of natural products/food sector portfolio into
               ethnic/specialty foods markets;

         o     Acquisition in August of MSD2D (Microsoft Developer to
               Developer), a high-tech media company serving the Exchange,
               SharePoint, .NET, and Security communities of IT professionals
               with a broad product portfolio, creating market synergies with
               Penton Windows IT Pro Group and TCI (conference group), and
               strengthening the Company's IT media business; and

         o     Partnership formed in August with Global Sources/CMP Media joint
               venture to publish Electronic Design - China, extending Penton
               Electronics Group's reach into the booming Asian market.


BALANCE SHEET/LIQUIDITY

    o Total debt at June 30, 2005, was $328.2m. As of June 30, Penton had access
      to $36.5m of its credit facility. The Company's financial position is
      strong and we have ample liquidity under our credit facility.
