Acquisition and sale to meet PAYE liabilities of shares under the terms of the
London Stock Exchange 2004 Long Term Incentive Plan ('the Plan').

On 24 August 2007 London Stock Exchange Group plc was notified that on 20 August
2007 certain of its senior executives received ordinary shares of 6 79/86 pence
in London Stock Exchange Group plc ('Shares') following the vesting of Matching
Share awards made under the Plan and that some of those Shares had been sold on
20 August to meet PAYE and National Insurance liabilities and dealing costs.

The Matching Awards were made on 20 August 2004 when, in return for the senior
executives purchasing Investment Shares, the Company granted matching awards
over such number of Shares that equaled two times the number of Shares that the
senior executives could have bought had the investment of his bonus been made on
a pre-tax basis (the Matching Award).  The Matching Awards vested in full on 20
August 2007 in accordance with the Plan rules and the specific performance
condition required for vesting.

In respect of Martin Graham, Nic Stuchfield and John Wallace (being persons
discharging managerial responsibilities), Halifax EES Trustees International
Limited, the trustee of the London Stock Exchange Employee Benefit Trust,
released 184,458 Shares to satisfy the vesting of their awards.  The individual
awards, numbers of Shares sold to meet PAYE and National Insurance liabilities
and dealing costs, the resulting Shares transferred to the individuals and the
resulting total beneficial holdings are shown in the following table:
