"The quarter ended November 30, 2004 was the first quarter in over 5 years in
which our earnings declined, but was in line with our expectations following the
exceptionally high level of cancellations we suffered in the previous quarter",
commented Chairman, Dr John Climax. " As predicted, this high cancellation
experience appears to have been an anomaly. With strong gross wins of $122
million, and cancellations of only $2 million in our most recent quarter, we
believe we have a solid foundation for a return to growth in Fiscal 2006
although we will need


further quarters of solid business wins to consolidate this. Nevertheless we are revising our EPS guidance for Fiscal 2005 to between $1.68 - $1.70. The rationale for this revision will be discussed in more detail on our conference call today" The company will hold its second quarter conference call today, January 6, 2005 at 8:00 EST [13:00 GMT / 14:00 CET].
