accordance with the terms and conditions set out in the appendix to this
announcement and will close by no later than 6.30pm today but may be closed

Principal terms of the Placing

Hoare Govett is arranging the Placing as agent for Marconi. The Placing will
establish a single price payable by all placees (the "Placing Price"). The

legally binding upon you to the extent that they are not varied or revoked prior

be retained by Marconi. Hoare Govett retains absolute discretion as to
allocations of Placing Shares. Any Placing Shares which are successfully
allocated to placees in the Placing ("Placing Participation") will be free of
stamp duty and stamp duty reserve tax (at a rate of 0.5 per cent.). No
commissions will be paid to placees or by placees in respect of any Placing
Participation. The contract created by the acceptance of a bid will be governed
by English law.
