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



On 3 March 2006 London Stock Exchange plc was notified that on that date Mourant
& Co Trustees Limited, the trustee of the London Stock Exchange Employee Benefit
Trust, purchased 13,108 ordinary shares of 55/6 pence each in the Company
(Shares) at a price of £8.59 per Share on behalf of the director noted below who
is participating in the London Stock Exchange Long 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 purchasing Investment Shares the Company has granted
her a matching award over such number of Shares that equals two times the number
of Shares that the director could have bought had the investment of his or her
bonus been made on a pre-tax basis (the Matching Award).

The following directors and senior executives (being persons discharging
managerial responsibilities) 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 at £8.59 per                            notification
                  share of which the
                  trustee is the
                  registered holder

Clara Furse       13,108                   44,444                   471,836 (of which 129,859
                                                                    are unvested)
                  0.005%
                                                                    0.18%



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 plc 2005 Annual Report.

Rule 3.1.4R(1)(a) and Disclosure Rule 3.1.4(R)(1)(b) (a disclosure made in
accordance with section 324 of the Companies Act 1985).
