                                                                 21 JANUARY 2004

                           ACQUISITION OF AMERSHAM PLC

                         SATISFACTION OF PRE-CONDITIONS

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")

On 10 October 2003, GE and Amersham announced the pre-conditional recommended
Acquisition of Amersham applying a share exchange ratio which, at announcement,
valued each Amersham share at 800 pence and the diluted share capital of
Amersham at approximately (pound)5.7 billion ($9.5 billion).

GE and Amersham today announce that the pre-conditions to the making of the
Acquisition have now been satisfied. The pre-conditions included regulatory
clearances from the European Commission, received today, and from the US
anti-trust authorities, received on 1 December 2003.

It is expected that Amersham's preliminary results for 2003 will be announced
and the documentation relating to the Scheme (which will incorporate Amersham's
preliminary results) will be despatched to Amersham shareholders in
approximately four weeks and it is intended that the Acquisition will complete
in early April. Full details of the terms and conditions and expected timetable
of the Acquisition and the Scheme will be set out in the scheme documentation.

Completion of the Acquisition remains subject to the satisfaction or, if
permitted, waiver of the conditions to the Acquisition as set out in the press
release of 10 October 2003, including, inter alia, the approval of Amersham
shareholders and the sanction of the Scheme by the High Court.

This document contains "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995. Forward-looking statements may
be identified by words such as "expects", "anticipates", "intends", "plans",
"believes", "seeks", "estimates", "will" or words of similar meaning and
include, but are not limited to, statements about the expected future business
and financial performance of GE resulting from and following the proposed
acquisition of Amersham. These statements are based on management's current
expectations and are inherently subject to uncertainties and changes in
circumstances. Among the factors that could cause actual results to differ
materially from those described in the forward-looking statements are factors
relating to satisfaction of the pre-conditions and the conditions to the making
and consummation of the proposed acquisition of Amersham, GE's ability to
successfully combine the businesses of GE Medical Systems and Amersham and to
realize expected operating synergies from the proposed acquisition of Amersham,
and changes in global, political, economic, business, competitive, market and
regulatory forces. More detailed information about certain of these factors is
contained in General Electric Company's and Amersham's filings with the SEC.
Neither GE nor Amersham undertakes any obligation to update the forward-looking
statements to reflect actual results, or any change in events, conditions,
assumptions or other factors.

The foregoing does not constitute an offer for sale of any securities or an
offer or an invitation to purchase any such securities. If and when GE commences
the proposed acquisition of Amersham and the acquisition is implemented by way
of a scheme of arrangement, any securities to be delivered pursuant to the
scheme of arrangement will not be registered under the Securities Act but will
be delivered in reliance on the exemption provided by Section 3(a)(10) thereof,
and Amersham will furnish the acquisition document to the SEC under cover of a
Form 6-K. If and when GE commences the proposed acquisition of Amersham and the
acquisition is implemented by way of an offer rather than a scheme of
arrangement, GE will file a registration statement relating to the offer with
the SEC. If GE files a registration statement with the SEC, it will contain a
prospectus and other documents relating to the offer. Such prospectus and other
documents will contain important information about GE, Amersham, the offer and
related matters. Holders of Amersham securities who are U.S. persons or who are
located in the United States are urged to read such prospectus (if any) and
other documents that would form part of such registration statement if and when
it becomes available before they make any decision with respect to the offer.
Holders of Amersham securities should also read the related
solicitation/recommendation statement on Schedule 14D-9 that will be filed with
the SEC by Amersham relating to the offer. Such prospectus and any other
relevant documents filed by GE and Amersham with the SEC will be available free
of charge at the SEC's web site at www.sec.gov and from GE. These documents will
also be available for inspection and copying at the public reference room
maintained by the SEC at 450 Fifth Street, N.W., Washington, D.C. 20549, US. For
further information about the public reference room, call the SEC at +1 800 732
0330.
