On 25 May 2007 London Stock Exchange Group plc was notified that on 24 May 2007

Exchange Employee Benefit Trust, purchased 20,245 ordinary shares of 6 79/86

Term Incentive Plan 2004 (the LTIP) whereby an employee undertakes to use a
percentage of their bonus to purchase Shares in the Company (Investment Shares)
and, in return, are granted a matching award of Shares.

In return for the director and senior executives purchasing Investment Shares
the Company has granted them matching awards over such number of Shares that
equals two times the number of Shares that the director and senior executives
could have bought had the investment of his or her bonus been made on a pre-tax
basis (the Matching Award).

managerial responsibilities) acquired interests in Shares under the LTIP as

To be eligible to receive the Matching Award, directors and senior executives
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 2006 Annual Report.
