BUHRMANN ANNOUNCES PRICING OF TENDER OFFER

        Buhrmann—one of the world's largest business-to-business suppliers of office products, computer supplies and business services—announced today the pricing in connection with its previously announced tender offer and consent solicitation (the "Tender Offer") for all of its USD 350 million of outstanding 121/4% Senior Subordinated Notes due 2009 (the "2009 Notes").

        The yield to maturity of the 73/4% U.S. Treasury Note due 15 November 2004 was 1.532% as of 28 June 2004. Accordingly, Buhrmann anticipates that each holder of 2009 Notes who tendered their 2009 Notes prior the 5:00 p.m., New York City time, on June 16, 2004 (the "Consent Payment Deadline") will receive total consideration of USD 1095.596 per USD 1,000 principal amount and that each holder of 2009 Notes who tendered after the Consent Payment Deadline will receive total consideration of USD 1085.596 per USD 1,000 principal amount. The Tender Offer is expected to close at 12:00 midnight, New York time on Wednesday 30 June 2004, and the settlement date for the Tender Offer is expected to be 1 July 2004. However, Buhrmann US Inc. may extend, amend, terminate or withdraw the Tender Offer at its discretion.
