Strengthens Commonwealth Business Media's Events Portfolio for Aviation
                            Intelligence Market

    LONDON, January 4 /PRNewswire-FirstCall/ -- United Business Media plc
announces today that its Commonwealth Business Media division has acquired
the UK-based Aviation Industry Group Ltd (AIG) for an initial cash
consideration of GBP6m, with a further consideration of up to GBP1m being
payable, depending on certain conditions being met.
    AIG organises 21 annual exhibitions and conferences for the aviation
industry, supported by three print titles and associated online platforms.
The exhibitions are held in the UK, with the conferences taking place
across the United States, Middle East, Asia Pacific and Europe.
Approximately 60% of AIG's GBP3m total revenues are generated from trade
shows and conferences.
    The acquisition will both extend Commonwealth Business Media's
geographical reach and enhance its product portfolio for the aviation
industry which includes BACK Aviation Solutions and the OAG business
acquired in December 2006.
    The acquisition is anticipated to meet UBM's 8% post-tax cost of
capital criterion in its first year of ownership.
    Alan Glass, President and Chief Executive Officer of Commonwealth
Business Media said:
    "I am delighted that we have completed the acquisition of AIG and I am
particularly pleased to welcome the AIG management team to Commonwealth
Business Media."
    "The acquisition of AIG strengthens Commonwealth's events and media
presence in the aviation market. This market offers us considerable growth
opportunities, particularly in the significant maintenance, repair and
overhaul segments - core strengths of both AIG and our existing BACK
business."
    "Coupled with our acquisition of OAG in December, the acquisition of
AIG means Commonwealth Business Media has an excellent multiple media
product offering for the aviation market and is well for positioned for
further growth."
