                   Management Bonus Plan ("Plan") Description

     Under the Plan, participants are eligible to receive a target bonus each
fiscal year equal to a fixed percentage of his or her base salary based upon
achievement of certain performance objectives. Senior management of the Company
determines which employees may participate in the Plan and the percentage of
base salary that may be earned, unless the employee has an agreement that
specifies otherwise.

     For all participants in the Plan, a portion of the target bonus depends
upon satisfaction of one or more Company-wide objectives and a portion of the
target bonus depends upon satisfaction of one or more personal objectives. For
fiscal 2002, regardless of achievement of personal objectives, no target bonuses
will be paid under the Plan unless the Company achieves a certain minimum
threshold performance. The relative share of the target bonus that is payable
based upon Company-wide objectives and payable based upon personal objectives is
the same for all participants. Senior management determines the Company-wide
objectives, while personal objectives are determined jointly by the
participant's manager and someone who is senior to the manager. Personal
objectives are measurable objectives that are linked directly to functional
goals specific to the participant and related strategic goals of the Company.

     During fiscal 2001, participants earned 40% of their target bonus based
upon whether the Company achieving an EBITDA target, 20% of their target bonus
based upon whether the Company achieved a return on capital employed (ROCE)
target and 20% of their target bonus based upon whether the Company achieved
customer satisfaction targets. The remaining 20% of target bonus was based upon
achievement of personal objectives, with half of that amount payable if a
participant achieved a minimum threshold performance, but did not achieve target
performance.
