Acquisition of shares under the terms of the London Stock Exchange 2004 Long
Term Incentive Plan

On 5 December 2007 London Stock Exchange Group plc was notified that on 4
December 2007 Massimo Capuano purchased 7,760 ordinary shares of 6 79/86 pence
each in the Company (Shares) in accordance with the Rules of the London Stock
Exchange Long Term Incentive Plan 2004 (the LTIP) whereby a participant
undertakes to purchase Shares in the Company (Investment Shares) and, in return,
is granted a matching award of Shares.

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

The following director acquired interests in Shares under the LTIP as follows:


Director/PDMR     Number and percentage of Number of Shares         Total beneficial holding of
                  issued class of          conditionally awarded    Shares and total percentage
                  Investment Shares        under the Matching Award beneficial holding following
                  purchased of which the                            notification
                  trustee is the
                  registered holder

Massimo Capuano   7,760 at £17.720254 per  30,318                   66,451
                  share
                                                                    0.02%
                  0.003%



To be eligible to receive the Matching Award, directors and senior executives
must hold their Investment Shares 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 Remuneration Report in the London
Stock Exchange Group plc 2007 Annual Report.
