  DAISYTEK OFFER DOCUMENT MAILED TO ISA SHAREHOLDERS; ACCEPTANCES REPRESENTING
               56.5% OF U.K. WHOLESALER'S ORDINARY SHARES IN HAND;
                         CLOSING COULD COME IN LATE JUNE

    ALLEN, Texas--(BUSINESS WIRE)--May 24, 2002--Daisytek International
Corporation (Nasdaq:DZTK), which announced on May 7 its intention to make a cash
offer for all of the ordinary share capital of ISA International plc (London
AIM: ISA.L), mailed a recommended offer to ISA shareholders Thursday.

    Mailing of the offer document sets a timetable in motion that could see the
deal closing as early as June 27. Daisytek, a $1.2 billion wholesale distributor
of computer and office supplies and provider of marketing and demand-generation
services, has already received irrevocable commitments to accept the offer in
respect of 56.5% of ISA ordinary shares. ISA's directors are recommending in the
offer document acceptance of Daisytek's proposal. Due to Daisytek's effective
control over ISA, Daisytek will consolidate ISA's results for approximately two
months of the first quarter of fiscal year 2003 regardless of the final closing
date or outcome of the offer.

    ISA -- one of the largest, publicly listed, pan-European computer supplies
distributors -- announced that its shareholders passed a resolution related to
borrowing limits at an extraordinary general meeting held Wednesday and that its
directors have approved the fiscal and calendar year 2001 financial statements.

    As Daisytek announced on May 7, the cash offer is 7.5 pence (approximately
$0.11) in cash for each ordinary share, which values the existing issued
ordinary share capital of ISA at approximately 4.4 million pounds sterling
(approximately $6.4 million). ISA shareholders are also being offered a share
alternative in unregistered Daisytek common stock.
