must leave their Investment Shares in the trust and remain in employment for a
period of three years from the date of grant of the Matching Award.  The actual
number of Shares transferred to a director or senior executive on the vesting of
the Matching Award will depend on the extent to which a corporate performance
target (which relates to the Company's Total Shareholder Return relative to a
group of comparator companies) is satisfied over the three-year vesting period.

Full details of the LTIP are provided in the report on directors' remuneration
in the London Stock Exchange Group plc 2005 Annual Report.
