Notes:

The RM plc Co-Investment Plan was approved by shareholders in January 2003. It
is a long-term incentive plan, which is designed to align the interests of RM's
senior executives with those of shareholders. Under the Plan, participating
senior executives are required to hold shares in RM and, if certain performance
conditions are achieved over a period of time, they are granted additional
shares.
