1. Amersham plc – Exchange Ratio

THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER TO PURCHASE OR A SOLICITATION OF AN OFFER TO SELL ANY SECURITIES

6 April 2004

ACQUISITION OF AMERSHAM PLC

EXCHANGE RATIO

Recommended share exchange acquisition of Amersham plc (“Amersham”) by General Electric Company and GE Investments, Inc. (together “GE”) by means of a scheme of arrangement (the “Scheme”) under section 425 of the Companies Act 1985 (the “Acquisition”)

Amersham and GE are pleased to announce that, at the first of the two Court hearings to be held this week, the High Court sanctioned the Scheme. The Scheme still remains conditional upon the confirmation by the High Court of the reduction of capital which forms part of the Scheme. It is expected that the Scheme will become effective on 8 April 2004.

Assuming that, as expected, the Scheme does become effective on 8 April 2004, the Exchange Ratio that will be used to calculate the number of New GE Shares to which holders of Amersham Securities will be entitled is 0.4833 and the ADS Exchange Ratio is 2.4165. The Exchange Ratio has been calculated by dividing £8.00 by the Final Sterling GE Price (as set out below) and the ADS Exchange Ratio has been calculated by multiplying the Exchange Ratio by five.

Trading in Amersham Shares on the London Stock Exchange and Amersham ADSs on the NYSE will be suspended from close of business today and the suspension of trading of entitlements to Amersham Shares on the Oslo Børs will continue. It is expected that the listing of Amersham Securities on the London, New York and Oslo stock exchanges will, in each case, be cancelled on the trading day on each such exchange immediately following the Scheme becoming effective.

Terms used in this announcement shall have the same meanings as set out in the Scheme document dated 17 February 2004.
