Summary

•           The boards of Drilling and Wireline Solutions Limited ('DWSL') and

reached agreement on the terms of a recommended cash offer to be made by DWSL, a
wholly-owned subsidiary of General Electric Company, for the entire issued and
to be issued share capital of Sondex (the 'Offer'). It is intended that the

the Companies Act.

•           Under the terms of the Offer, Scheme Shareholders will receive 460
pence in cash for each Sondex Share.

•           The Offer values Sondex's existing issued share capital at
approximately £262.7 million and the entire issued and to be issued share
capital at approximately £288.7 million.

•           The Offer of 460 pence per Sondex Share represents a premium of
approximately:

-        35.5 per cent. to the Closing Price of 339.5 pence per Sondex Share on
30 August 2007, being the last Business Day prior to the date of the
announcement by Sondex that it was in discussions in relation to a possible
offer; and

-        38.1 per cent. to the average Closing Price of approximately 333.2
pence per Sondex Share for the 30 days ended 30 August 2007.

•           The directors of Sondex, who have been so advised by Investec,
consider the terms of the Offer to be fair and reasonable. In providing its
advice, Investec has taken into account the commercial assessments of the
directors of Sondex. Accordingly, the directors of Sondex will unanimously
recommend that Sondex Shareholders vote in favour of the Scheme and the
resolutions at the Court Meeting and the EGM.

•           DWSL has received irrevocable undertakings to vote in favour of the
Scheme and the resolutions at the Court Meeting and the EGM from the directors
of Sondex in respect of all of their own beneficial shareholdings of Sondex
Shares (and, where applicable, of their connected persons) amounting, in

undertakings and non-binding letters of intent to vote in favour of the Scheme
and the resolutions at the Court Meeting and the EGM from Sondex Shareholders in

of Sondex's entire existing issued share capital.

equipment to oilfield service companies that run operations at well-sites on
behalf of oil or gas companies. Sondex equipment is used by leading operators
and service companies worldwide and has established a reputation for quality and
reliability.

significantly, both organically and through international acquisitions,
increasing its market capitalisation from £38.8 million on 12 June 2003 to
£193.9 million on 30 August 2007. As at 28 February 2007, the Sondex Group
employed 513 staff in nine countries. Corporate and financial growth has been
matched by operational progress, with Sondex's product range constantly being
expanded and upgraded, driven by an annual investment of approximately 10 per
cent. of revenues in research and development.

financial services company, with products and services ranging from aircraft
engines, power generation, water processing and sensor technology to medical

Optimization and Control business.

Commenting on the Offer, Brian Palmer, Vice President of GE Energy's
Optimization and Control business, said:

complementing our existing Tensor product line. The company brings to us a broad
range of advanced products and technologies, as well as employees with a deep
understanding of the customers they serve. We expect the combination to form a
substantial growth business for GE going forward.'

Commenting on the Offer, Iain Paterson, chairman of Sondex, said:

prospects and the directors are unanimous in recommending Sondex Shareholders to

ability to realise the value of their holdings at an attractive premium to the
historic share price. The team at Sondex look forward to working in partnership
with our new colleagues at GE Energy to continue to drive the business forwards.
'

Commenting on the proposed transaction, Martin Perry, CEO of Sondex said:

'The acquisition of Sondex by DWSL is an exciting move for our company and
employees. With GE Energy, we will have greater resources to further develop
innovative new technologies and we will be able to provide an enhanced level of
global support to our customers.'

subscribe for or an invitation to purchase or subscribe for any securities or
the solicitation of any vote or approval in any jurisdiction pursuant to the
Offer or otherwise. Any response in relation to the Offer should be made only on
the basis of the information in the Scheme Document or any document by which the
Offer is made. Sondex will prepare the Scheme Document to be distributed to
Sondex Shareholders. Sondex and DWSL urge Sondex Shareholders to read the Scheme
Document when it becomes available because it will contain important information
relating to the Offer.


Investec, which is authorised and regulated in the United Kingdom by the

in connection with the Offer and will not be responsible to anyone other than
Sondex for providing the protections afforded to clients of Investec or for

The availability of the Offer to Sondex Shareholders who are not resident in and
citizens of the United Kingdom may be affected by the laws of the relevant
jurisdictions in which they are located or of which they are citizens. Such
persons should inform themselves of, and observe, any applicable legal or
regulatory requirements of their jurisdictions. Further details in relation to

The distribution of this announcement in jurisdictions other than in the United
Kingdom may be restricted by law and therefore any persons who are subject to
the laws of any jurisdiction other than the United Kingdom should inform
themselves about, and observe, any applicable requirements. This announcement
has been prepared for the purposes of complying with English law and the City
Code and the information disclosed may not be the same as that which would have

Notice to US investors



The Offer relates to the shares in an English company and is being made by means
of a scheme of arrangement provided for under English company law. A transaction
effected by means of a scheme of arrangement is not subject to the proxy and
tender offer rules under the US Exchange Act. Accordingly, the Offer is subject
to the disclosure requirements and practices applicable in the UK to schemes of

may not be able to sue Sondex, DWSL or General Electric Company in a non-US
court for violations of US securities laws.



Neither the SEC nor any securities commission of any state of the United States
has (a) approved or disapproved of the Offer; (b) passed upon the merits or
fairness of the Offer; or (c) passed upon the adequacy or accuracy of the
disclosure in this document. Any representation to the contrary is a criminal
offence in the United States.



Forward-Looking Statements



This announcement, oral statements made regarding the Offer, and other
information published by General Electric Company, GE Energy, DWSL and Sondex
contain 'forward-looking statements'. These statements are based on the current
expectations of the management of General Electric Company, GE Energy, DWSL and
Sondex and are naturally subject to uncertainty and changes in circumstances.
The forward-looking statements contained herein include statements about the
expected effects of the Offer on Sondex and DWSL, the expected timing and scope
of the Offer, enhanced customer support, access to greater resources and other
synergies, other strategic options and all other statements in this announcement
other than historical facts. Forward-looking statements include, without
limitation, statements typically containing words such as 'intends', 'expects',
'anticipates', 'believes', 'estimates', 'will' 'may' and 'should' and words of
similar import. By their nature, forward-looking statements involve risk and
uncertainty because they relate to events and depend on circumstances that will
occur in the future. There are a number of factors that could cause actual
results and developments to differ materially from those expressed or implied by
such forward-looking statements. These factors include, but are not limited to,
the satisfaction of the Conditions to the Offer, as well as additional factors,
such as changes in economic conditions, changes in the level of capital
investment, success of business and operating initiatives and restructuring
objectives, customers' strategies and stability, changes in the regulatory
environment, fluctuations in interest and exchange rates, the outcome of
litigation, government actions and natural phenomena such as floods, earthquakes
and hurricanes. Other unknown or unpredictable factors could cause actual
results to differ materially from those in the forward-looking statements.
Neither General Electric Company, GE Energy, DWSL, nor Sondex undertakes any
obligation to update publicly or revise forward-looking statements, whether as a
result of new information, future events or otherwise, except to the extent
legally required.



Dealing Disclosure Requirements

'interested' (directly or indirectly) in 1 per cent. or more of any class of
'relevant securities' of Sondex, all 'dealings' in any 'relevant securities' of
Sondex (including by means of an option in respect of, or a derivative
referenced to, any such 'relevant securities') must be publicly disclosed by no
later than 3.30 p.m. (London time) on the Business Day following the date of the
relevant transaction. This requirement will continue until the date on which the
Offer becomes effective, lapses or is otherwise withdrawn or on which the 'offer
period' otherwise ends. If two or more persons act together pursuant to an
agreement or understanding, whether formal or informal, to acquire an 'interest'
in 'relevant securities' of Sondex, they will be deemed to be a single person
for the purpose of Rule 8.3.



Under the provisions of Rule 8.1 of the City Code, all 'dealings' in 'relevant
securities' of Sondex by DWSL or Sondex, or by any of their respective
'associates', must be disclosed by no later than 12.00 noon (London time) on the

securities' 'dealings' should be disclosed, and the number of such securities in
issue, can be found on the Panel's website at http://
www.thetakeoverpanel.org.uk.



'Interests in securities' arise, in summary, when a person has long economic

securities. In particular, a person will be treated as having an 'interest' by
virtue of the ownership or control of securities, or by virtue of any option in
respect of, or derivative referenced to, securities.

                                    Limited,
             a wholly-owned subsidiary of General Electric Company



1.                Introduction

The boards of Drilling and Wireline Solutions Limited ('DWSL') and Sondex PLC ('
Sondex' or the 'Company') are pleased to announce that they have reached
agreement on the terms of a recommended cash offer to be made by DWSL, a
wholly-owned subsidiary of General Electric Company, for the entire issued and
to be issued share capital of Sondex (the 'Offer').

2.                The Offer

It is intended that the Offer be implemented by way of a scheme of arrangement
under section 425 of the Companies Act.

           Under the Offer, which will be subject to the Conditions and further
terms set out in Appendix 1 to this announcement and to be set out in the Scheme
Document, Scheme Shareholders will be entitled to receive:

for each Sondex Share                                          460 pence in cash



The Offer values Sondex's existing issued share capital at approximately £262.7
million and the entire issued and to be issued share capital at approximately
£288.7 million.

The Offer of 460 pence per Sondex Share represents a premium of approximately:

-        35.5 per cent. to the Closing Price of 339.5 pence per Sondex Share on
30 August 2007, being the last Business Day prior to the date of the
announcement by Sondex that it was in discussions in relation to a possible
offer; and

-        38.1 per cent. to the average Closing Price of approximately 333.2
pence per Sondex Share for the 30 days ended 30 August 2007.

3.                Recommendation

The directors of Sondex, who have been so advised by Investec, consider the
terms of the Offer to be fair and reasonable. In providing its advice, Investec
has taken into account the commercial assessments of the directors of Sondex.
Accordingly, the directors of Sondex will unanimously recommend that Sondex
Shareholders vote in favour of the Scheme and the resolutions at the Court
Meeting and the EGM, as they have irrevocably undertaken to do in respect of
their own beneficial shareholdings.



4.                Background to, and reasons for, recommending the Offer

The Company listed on the Official List of the London Stock Exchange in June
2003. Since then the Company has:

-        grown sales from £17.5 million for the year ended February 2004 to
£68.5 million for the year ended February 2007; and

-        increased its share price from 100 pence per share to 339.5 pence per
share (the Closing Price on 30 August 2007 being the last Business Day prior to
the date of the announcement by Sondex that it was in discussions in relation to
a possible offer) and its market capitalisation from £38.8 million on 12 June
2003 to £193.9 million on 30 August 2007 (based on the Closing Price on the last
Business Day prior to the date of the announcement by Sondex that it was in
discussions in relation to a possible offer).

Sondex operates in the oil services markets which have been experiencing a
period of strong growth and consolidation.

During the first half of 2007, the Company was approached by a number of
companies that operate in the same industry as Sondex, with a view to their
acquiring the Company. As a result the directors decided to undertake a
confidential process to establish if an acceptable offer for the Company was
available.

The confidential process involved discussions with those parties who had
expressed an interest and a number of other companies which the directors
considered might be interested in acquiring the Company. The result of the
confidential process is the Offer from DWSL.

In considering whether to recommend the Offer, the directors of Sondex have
taken into account the following:

-        a process involving a number of interested parties was carried out to
establish the best price available from these parties;

-        the Offer represents both fair value to Sondex Shareholders today and
additional value for foregoing the opportunity to participate in the future
growth available to the Company; and

-        the Offer represents an opportunity for Sondex Shareholders to realise
their entire investment in Sondex, in cash at a premium, within a relatively
short period of time.

5.                Background to and reasons for the Offer

General Electric Company views Sondex as an attractive addition to its portfolio
of businesses and an opportunity to enhance GE Energy's participation in a high
growth segment of the oilfield technology industry. Sondex's products are
complementary to the product range of GE Energy's Optimization and Control
business and Sondex brings a pipeline of innovative new technologies that will
further expand GE Energy's offering to its customers. General Electric Company
believes that GE Energy's knowledge of the oil and gas sector combined with the
skills and experience of the employees and management of Sondex will provide GE
Energy with a well-positioned platform for continued growth.

GE Energy has served the oil and gas exploration and production industry with
specialised equipment from its Reuter Stokes Measurement Solutions product lines
for over 30 years. The Sondex acquisition will expand the product portfolio and
allow customers worldwide to benefit from the combined capabilities, capacity
and resources of the two businesses.

6.                Information on Sondex

Sondex designs, manufactures and markets electro-mechanical based equipment to
oilfield service companies that run operations at well-sites on behalf of oil or
gas companies. Sondex equipment is used by leading operators and service
companies worldwide and has established a reputation for quality and
reliability.

Corporate and financial growth has been matched by operational progress. The
product range is constantly being expanded and upgraded, driven by an annual
investment of approximately 10 per cent. of revenues in research and
development.

For the year ended 28 February 2007, Sondex's turnover was £68.5 million (2006:
£51.4 million), profit before tax was £8.5 million (2006: £7.5 million). The net
assets of Sondex as at 28 February 2007 were £70.2 million (2006: £59.9
million).

Further information on Sondex is available on its website at www.sondex.com.

7.                Current Trading and Prospects of Sondex

Market conditions have remained favourable as operators of oil and gas fields
continue to turn to sophisticated technologies and instruments, such as those
supplied by Sondex, to optimise recovery from maturing oil and gas fields.
Revenues for the first half of the financial year have benefited from these good
market conditions and the position of Sondex's products in the industry.

The directors of Sondex are confident in the trading prospects of the Sondex
Group for the current financial year.

8.                Information on DWSL and General Electric Company

DWSL is a private company incorporated in the United Kingdom for the purpose of
implementing the Offer. DWSL has not traded since its incorporation and its sole
current activity relates to the implementation of the Offer. DWSL is a
wholly-owned subsidiary of General Electric Company.

9.                Irrevocable Undertakings

DWSL has received irrevocable undertakings to vote in favour of the Scheme and
the resolutions at the Court Meeting and the EGM from the directors of Sondex in
respect of all of their own beneficial holdings of Sondex Shares (and, where
applicable, their connected persons) amounting, in aggregate, to 3,636,982
Sondex Shares, representing approximately 6.4 per cent. of Sondex's entire
existing issued share capital. These undertakings will remain binding in the
event of a competing offer being made for Sondex.

DWSL has also received non-binding letters of intent to vote in favour of the
Scheme and the resolutions at the Court Meeting and the EGM from Sondex
Shareholders in respect of, in aggregate, 21,595,763 Sondex Shares, representing
a further 37.8 per cent. of Sondex's entire existing issued share capital.

Accordingly, DWSL has received, in aggregate, irrevocable undertakings and
non-binding letters of intent to vote in favour of the Scheme and the
resolutions at the Court Meeting and the EGM from Sondex Shareholders in respect
of 25,232,745 Sondex Shares, representing approximately 44.2 per cent. of
Sondex's entire existing issued share capital.

Further details of these irrevocable undertakings and non-binding letters of
intent are set out in Appendix 3 to this announcement.

10.             Structure of the Offer

The Offer is expected to be effected by means of a scheme of arrangement between
Sondex and the Scheme Shareholders under section 425 of the Companies Act. The
procedure involves an application by Sondex to the Court to sanction the Scheme
and to confirm the cancellation of all the Scheme Shares, in consideration for
which the Scheme Shareholders will receive cash on the basis set out above.

Before the Final Court Order can be sought, the Scheme will require approval by
Scheme Shareholders at a Court convened meeting and approval of the Sondex
Shareholders of certain resolutions to be proposed at the EGM.

The Court Meeting will be convened by order of the Court for the purposes of
considering and, if thought fit, approving the Scheme (with or without
modification). The Scheme will be approved at the Court Meeting if a majority in
number representing not less than 75 per cent. in value of the Scheme
Shareholders present and voting, either in person or by proxy, votes in favour
of the Scheme.

The EGM will be convened for the purposes of considering and, if thought fit,
passing a special resolution to approve the reduction of Sondex's share capital
and the amendments to the articles of association of Sondex necessary to
implement the Scheme and any other resolutions that may be necessary.

Once the necessary approvals from the Sondex Shareholders have been obtained and
the other Conditions have been satisfied or (where applicable) waived, the
Scheme will become effective upon sanction by the Court and registration of the
Final Court Order by the Registrar of Companies. Upon the Scheme becoming
effective, it will be binding on all Scheme Shareholders, irrespective of
whether or not they attended or voted at the Court Meeting or the EGM.

Under the Scheme, each Scheme Share will be cancelled and new Sondex Shares will
be issued fully paid to DWSL. In consideration for the cancellation of their
Scheme Shares, Scheme Shareholders will receive consideration under the terms of
the Offer as set out above.

It is intended that, following the Scheme becoming effective, and subject to
applicable requirements of the London Stock Exchange, DWSL will procure that
Sondex apply to the London Stock Exchange for the Sondex Shares to cease trading
and to the UK Listing Authority to remove the Sondex Shares from the Official
List. It is also intended that Sondex will be re-registered as a private limited
company as part of the Scheme.

DWSL and Sondex have agreed that, if DWSL so elects, the Offer may be
implemented by way of a takeover offer. In this event, that offer will be
implemented on the same terms, so far as applicable, as those which would apply
to the Scheme. If DWSL does elect to implement the Offer by way of a takeover
offer, and if sufficient acceptances of such offer are received and/or
sufficient Sondex Shares are otherwise acquired, it is the intention of DWSL to
apply the provisions of sections 979 to 982 (inclusive) of the Companies Act
2006 to acquire compulsorily any outstanding Sondex Shares to which such offer
relates.

11.             Expected Timetable

It is intended that the Scheme Document containing further details of the Scheme
will shortly be despatched to Sondex Shareholders and, for information only, to
participants in the Sondex Share Schemes. The Meetings will be held in October.
The Scheme Document will include the notices of the Meetings and full details of
the Scheme together with the expected timetable, and will specify the necessary
actions to be taken by the Sondex Shareholders. The Scheme is expected to become
effective by 26 October 2007 and the consideration due to Scheme Shareholders is
expected to be despatched on the Effective Date.

12.             Financing the Offer

The cash consideration payable by DWSL to Scheme Shareholders under the Offer
will be funded using existing cash resources of the GE Group.

Credit Suisse, financial adviser to DWSL, is satisfied that sufficient financial
resources are available to DWSL to enable it to satisfy in full the cash
consideration payable under the Offer.

13.            Management, employees and pensions

DWSL values highly the skills, knowledge and expertise of Sondex's existing
management and employees. DWSL has given assurances to the directors of Sondex
that the existing employment rights of the management and employees of Sondex
will be safeguarded upon the Scheme becoming effective.

14.             Sondex Share Schemes

Participants in the Sondex Share Schemes will be contacted regarding the effect
of the Offer on their rights under these schemes and appropriate proposals will
be made to such participants in due course.

15.             Arrangements between DWSL and Sondex in relation to the Offer

Sondex and DWSL have entered into an agreement in respect of various matters
related to the Offer (the 'Offer Agreement').

Under the Offer Agreement Sondex has agreed to pay DWSL an inducement fee of
£2,886,700 (plus VAT to the extent it is fully recoverable by Sondex) if, in
summary: (i) a competing proposal for Sondex is made before the Offer lapses or
is withdrawn and that proposal or any other competing proposal is completed;
(ii) the directors of Sondex withdraw or modify their recommendation of the

Sondex has also agreed in the Offer Agreement that if it receives an approach
relating to a competing proposal for Sondex which it intends to recommend
instead of the Offer, it will notify DWSL of the terms of that competing
proposal and will not withdraw or modify its recommendation of the Offer unless
either: (i) DWSL informs Sondex that it is not willing to revise the Offer such

not, within 72 hours of being notified of the competing proposal, confirm that
it is willing to revise the Offer such that the directors of Sondex determine to
continue to recommend the Offer; or (iii) DWSL, having confirmed within 72 hours
of being notified of the competing proposal that it is willing to revise its
Offer such that the directors of Sondex determine to continue to recommend the
Offer, fails within 108 hours of receipt of such notice to announce such revised
Offer.

The Offer Agreement also contains non-solicitation obligations on the part of
Sondex in relation to competing proposals and obligations on Sondex to notify
DWSL about other approaches from any bona fide potential offeror in relation to
competing proposals.

16.             Disclosure of interests in Sondex

Save for the irrevocable undertakings referred to in paragraph 9 above, as at
the close of business on 31 August 2007, the last Business Day prior to the date
of this announcement, neither General Electric Company, DWSL, nor any of the
directors of General Electric Company or DWSL, nor, so far as General Electric
Company or DWSL are aware, any person acting in concert with General Electric
Company or DWSL has any interest in, or right to subscribe for, any Sondex
Shares or securities convertible or exchangeable into Sondex Shares ('Sondex
Securities'), nor does any such person have any short position (whether
conditional or absolute and whether in the money or otherwise) including short
positions under derivatives or arrangement in relation to Sondex Securities. For
these purposes, 'arrangement' includes any indemnity or option arrangement or
any agreement or understanding, formal or informal, of whatever nature, relating
to Sondex Securities which may be an inducement to deal or refrain from dealing
in such securities. In the interests of secrecy prior to this announcement, DWSL
has not made any enquiries in this respect of the matters referred to in this
paragraph of certain parties who may be deemed by the Panel to be acting in
concert with them for the purposes of the Scheme. Enquiries of such parties will
be made as soon as practicable following the date of this announcement and any
material disclosure in respect of such parties will be included in the Scheme
Document.

17.            General

The Offer will comply with the applicable rules and regulations of the UK
Listing Authority, the London Stock Exchange and the City Code. The Offer will
be governed by English law and will be subject to the jurisdiction of the
English courts and the Conditions and further terms set out in Appendix 1 to
this announcement and to be set out in the Scheme Document.

The bases and sources of certain financial information contained in this
announcement are set out in Appendix 2 to this announcement.

Certain terms used in this announcement are defined in Appendix 4 to this
announcement.

This announcement is not intended to and does not constitute an offer to sell or
subscribe for or an invitation to purchase or subscribe for any securities or
the solicitation of any vote or approval in any jurisdiction pursuant to the
Offer or otherwise. Any response in relation to the Offer should be made only on
the basis of the information in the Scheme Document or any document by which the
Offer is made. Sondex will prepare the Scheme Document to be distributed to
Sondex Shareholders. Sondex and DWSL urge Sondex Shareholders to read the Scheme
Document when it becomes available because it will contain important information
relating to the Offer.



Investec, which is authorised and regulated in the United Kingdom by the
Financial Services Authority, is acting exclusively for Sondex and no-one else
in connection with the Offer and will not be responsible to anyone other than
Sondex for providing the protections afforded to clients of Investec or for
providing advice in relation to the Offer.


Credit Suisse, which is authorised and regulated in the United Kingdom by the
Financial Services Authority, is acting exclusively for General Electric Company
and DWSL and no-one else in connection with the Offer and will not be
responsible to anyone other than General Electric Company or DWSL for providing
the protections afforded to clients of Credit Suisse or for providing advice in
relation to the Offer or to the matters referred to herein.



The availability of the Offer to Sondex Shareholders who are not resident in and
citizens of the United Kingdom may be affected by the laws of the relevant
jurisdictions in which they are located or of which they are citizens. Such
persons should inform themselves of, and observe, any applicable legal or
regulatory requirements of their jurisdictions. Further details in relation to
overseas shareholders will be contained in the Scheme Document.



The distribution of this announcement in jurisdictions other than in the United
Kingdom may be restricted by law and therefore any persons who are subject to
the laws of any jurisdiction other than the United Kingdom should inform
themselves about, and observe any applicable requirements. This announcement has
been prepared for the purposes of complying with English law and the City Code
and the information disclosed may not be the same as that which would have been
disclosed if this announcement had been prepared in accordance with the laws of
any jurisdiction outside the United Kingdom.



If the transaction is carried out by way of offer, the Offer will not be made,
directly or indirectly, in, into or from any jurisdiction where to do so would
violate the laws in that jurisdiction. Accordingly, copies of this announcement
and formal documentation relating to the Offer will not be and must not be,
mailed or otherwise forwarded, distributed or sent in, into or from any
jurisdiction where to do so would violate the laws in that jurisdiction.



Notice to US investors



The Offer relates to the shares in an English company and is being made by means
of a scheme of arrangement provided for under English company law. A transaction
effected by means of a scheme of arrangement is not subject to the proxy and
tender offer rules under the US Exchange Act. Accordingly, the Offer is subject
to the disclosure requirements and practices applicable in the UK to schemes of
arrangement which differ from the disclosure requirements of the US proxy and
tender offer rules. If DWSL exercises its right to implement the Offer by way of
a takeover offer, the Offer will be made in compliance with applicable US laws
and regulations.



Sondex is organised under the laws of England. All of the directors of Sondex
and most of its officers are residents of countries other than the United
States, and most of the assets of Sondex are located outside of the United
States. DWSL is a newly incorporated UK company wholly-owned by General Electric
Company, a New York corporation, and formed in connection with the Offer. You
may not be able to sue Sondex, DWSL or General Electric Company in a non-US
court for violations of US securities laws.



Neither the SEC nor any securities commission of any state of the United States
has (a) approved or disapproved of the Offer; (b) passed upon the merits or
fairness of the Offer; or (c) passed upon the adequacy or accuracy of the
disclosure in this document. Any representation to the contrary is a criminal
offence in the United States.



Forward-Looking Statements



This announcement, oral statements made regarding the Offer, and other
information published by General Electric Company, GE Energy, DWSL and Sondex
contain 'forward-looking statements'. These statements are based on the current
expectations of the management of General Electric Company, GE Energy, DWSL and
Sondex and are naturally subject to uncertainty and changes in circumstances.
The forward-looking statements contained herein include statements about the
expected effects of the Offer on Sondex and DWSL, the expected timing and scope
of the Offer, enhanced customer support, access to greater resources and other
synergies, other strategic options and all other statements in this announcement
other than historical facts. Forward-looking statements include, without
limitation, statements typically containing words such as 'intends', 'expects',
'anticipates', 'believes', 'estimates', 'will' 'may' and 'should' and words of
similar import. By their nature, forward-looking statements involve risk and
uncertainty because they relate to events and depend on circumstances that will
occur in the future. There are a number of factors that could cause actual
results and developments to differ materially from those expressed or implied by
such forward-looking statements. These factors include, but are not limited to,
the satisfaction of the Conditions to the Offer, as well as additional factors,
such as changes in economic conditions, changes in the level of capital
investment, success of business and operating initiatives and restructuring
objectives, customers' strategies and stability, changes in the regulatory
environment, fluctuations in interest and exchange rates, the outcome of
litigation, government actions and natural phenomena such as floods, earthquakes
and hurricanes. Other unknown or unpredictable factors could cause actual
results to differ materially from those in the forward-looking statements.
Neither General Electric Company, GE Energy, DWSL, nor Sondex undertakes any
obligation to update publicly or revise forward-looking statements, whether as a
result of new information, future events or otherwise, except to the extent
legally required.



Dealing Disclosure Requirements



Under the provisions of Rule 8.3 of the City Code, if any person is, or becomes,
'interested' (directly or indirectly) in 1 per cent. or more of any class of
'relevant securities' of Sondex, all 'dealings' in any 'relevant securities' of
Sondex (including by means of an option in respect of, or a derivative
referenced to, any such 'relevant securities') must be publicly disclosed by no
later than 3.30 p.m. (London time) on the Business Day following the date of the
relevant transaction. This requirement will continue until the date on which the
Offer becomes effective lapses or is otherwise withdrawn or on which the 'offer
period' otherwise ends. If two or more persons act together pursuant to an
agreement or understanding, whether formal or informal, to acquire an 'interest'
in 'relevant securities' of Sondex, they will be deemed to be a single person
for the purpose of Rule 8.3.



Under the provisions of Rule 8.1 of the City Code, all 'dealings' in 'relevant
securities' of Sondex by DWSL or Sondex, or by any of their respective
'associates', must be disclosed by no later than 12.00 noon (London time) on the
Business Day following the date of the relevant transaction.



A disclosure table, giving details of the companies in whose 'relevant
securities' 'dealings' should be disclosed, and the number of such securities in
issue, can be found on the Panel's website at http://
www.thetakeoverpanel.org.uk.



'Interests in securities' arise, in summary, when a person has long economic
exposure, whether conditional or absolute, to changes in the price of
securities. In particular, a person will be treated as having an 'interest' by
virtue of the ownership or control of securities, or by virtue of any option in
respect of, or derivative referenced to, securities.



Terms in quotation marks are defined in the City Code, which can also be found
on the Panel's website. If you are in any doubt as to the application of Rule 8
to you, please contact an independent financial adviser authorised under the
Financial Services and Markets Act 2000, or consult the Panel's website at
www.thetakeoverpanel.org.uk.

shall be under no obligation to waive or treat as fulfilled any of Conditions 3
(A) to 3(H) inclusive by a date earlier than the date specified in Condition 1
for the fulfilment thereof, notwithstanding that other of Conditions 3(A) to 3
(H) inclusive may at such earlier date have been waived or fulfilled and that
there are at such earlier date no circumstances indicating that any of such
Conditions may not be capable of fulfilment.

under Rule 9 of the City Code, DWSL may make such alterations to the above
Conditions as are necessary to comply with that Rule.

6.      The Offer will lapse (unless otherwise agreed by the Panel) if,
following the posting of the Scheme Document, there is a referral in respect of
the Offer by the Office of Fair Trading to the Competition Commission before the

DWSL reserves the absolute right to elect to implement the Offer by way of a
takeover offer as it may determine in its absolute discretion. In such event,
such offer will be implemented on the same terms (subject to appropriate
amendments, including (without limitation) an acceptance condition set at 90 per
cent. (or such lesser percentage (being more than 50 per cent.) as DWSL may
decide) of the Sondex Shares to which such offer relates), so far as applicable,
as those which would apply to the Scheme.

PART B: Certain further terms of the Offer

1.      For the purpose of these Conditions, a Third Party shall be regarded as
having 'intervened' if it has decided to take, institute, implement or threaten
any action, proceeding, suit, investigation, enquiry or reference or made,
proposed or enacted any statute, regulation, decision or order or taken any
measures or other steps or required any action to be taken or information to be
provided or otherwise having done anything, and 'intervene' shall be construed
accordingly.

2.      The Sondex Shares will be acquired by DWSL fully paid and free from all
liens, equitable interests, charges, encumbrances, rights of pre-emption and
other third party rights of any nature whatsoever and together with all rights
now or hereafter attaching thereto including the right to receive and retain all
dividends and other distributions (if any) announced, declared or paid on or
after the date of this announcement.

3.      The Offer will be subject, amongst other things, to those terms which
will be set out in the Scheme Document and such further terms as may be required
to comply with the Listing Rules and the provisions of the City Code.

4.      The availability of the Offer to persons not resident in the United
Kingdom may be affected by the laws of the relevant jurisdictions. Persons who
are not resident in the United Kingdom should inform themselves about and
