COMPANIES FORM No. 429(4)

NOTICE TO NON-ASSENTING SHAREHOLDERS

                                                                          429(4)

Pursuant to Section 429(4) of the Companies Act 1985 as inserted by Schedule 12
to the Financial Services Act 1986

A takeover offer (the "OFFER") was made on 28 March 2002 by GBV Funfte
Gesellschaft fur Beteiligungsverwaltung mbH (the "OFFEROR"), a wholly-owned
subsidiary of RWE AG and (outside the United States) by Merrill Lynch on its
behalf for the whole of the issued share capital (including Innogy Shares
represented by Innogy ADSs) of Innogy Holdings plc ("INNOGY") and any further
ordinary shares of Innogy which are unconditionally allotted or issued before
the date on which the Offer closes.

The terms of the Offer are set out in the offer document dated 28 March, 2002
(the "OFFER DOCUMENT"). The definitions set out in that document apply to this
notice unless the context otherwise requires. The Offeror has, within four
months of making the Offer, acquired or contracted to acquire not less than
nine-tenths in value of the Innogy Shares (including Innogy Shares represented
by Innogy ADSs) to which the Offer relates. The Offeror gives notice that it now
intends to exercise its right under section 429 of the Companies Act 1985 to
acquire the Innogy Shares held by you.

The terms of the Offer provide for the Innogy Shares to be acquired on the
following basis:

          FOR EACH INNOGY SHARE     275 PENCE IN CASH

Alternatively (except, as described in the Offer Document, in the case of
certain overseas shareholders) you may elect to receive Loan Notes in lieu of
some or all of the cash consideration which you would otherwise receive under
the Offer on the basis of (pound)1 nominal value of Loan Notes for every
(pound)1 of cash otherwise receivable under the Offer.

As these terms include a choice of consideration, you should, within six weeks
of the date of this notice, inform the Offeror in writing at Lloyds TSB
Registrars, Antholin House, 71 Queen Street, London, EC4N 1SL which of the
choices you wish to accept. If you fail to make a choice and do not make
application to the Court (see note below), the Offeror will acquire your Innogy
Shares on the basis of 275 pence in cash for each Innogy Share.

The Offer (including the Loan Note Alternative) is not being made, directly or
indirectly, in or into Australia, Canada or Japan and the Offer is not capable
of acceptance from or within Australia, Canada or Japan. Accordingly, copies of
the Offer Document or any related documents are not being, and must not be,
mailed or otherwise forwarded, distributed or sent in, into or from Australia,
Canada or Japan.

The Loan Notes have not been, and will not be, listed on any stock exchange and
have not been, and will not be, registered under the US Securities Act or under
any relevant laws of any state or other jurisdiction of the United States, nor
have the clearances been, nor will they be, obtained from the securities
commission or similar authority of any province or territory of Canada and no
prospectus has been, or will be, filed, or



registration made, under any securities law of any province or territory of
Canada, nor has a prospectus in relation to the Loan Notes been, nor will one
be, lodged with, or registered by, the Australian Securities and Investments
Commission, nor have any steps been taken, nor will any steps be taken, to
enable the Loan Notes to be offered in compliance with applicable securities
laws of Japan. Accordingly, unless an exemption under relevant securities laws
is available, the Loan Notes may not be offered, sold, re-sold or delivered,
directly or indirectly, in, into or from the United States, Australia, Canada or
Japan or any other jurisdiction in which an offer of Loan Notes would constitute
a violation of relevant laws or require registration of the Loan Notes, or to or
for the account or benefit of any US person or resident of Australia, Canada or
Japan or any other such jurisdiction.

NOTE: YOU ARE ENTITLED UNDER SECTION 430C OF THE COMPANIES ACT 1985 TO MAKE AN
APPLICATION TO THE COURT WITHIN SIX WEEKS OF THE DATE OF THIS NOTICE FOR AN
ORDER EITHER THAT THE OFFEROR SHALL NOT BE ENTITLED AND BOUND TO ACQUIRE YOUR
INNOGY SHARES OR THAT DIFFERENT TERMS TO THOSE OF THE OFFER SHALL APPLY TO THE
ACQUISITION. IF YOU ARE CONTEMPLATING SUCH AN ACTION YOU MAY WISH TO SEEK LEGAL
ADVICE.

Signed                                                      Dated: 5 June 2002

        THIS DOCUMENT IS IMPORTANT AND REQUIRES YOUR IMMEDIATE ATTENTION

IF YOU ARE IN ANY DOUBT ABOUT THE ACTION YOU SHOULD TAKE, YOU SHOULD IMMEDIATELY
CONSULT YOUR STOCKBROKER, BANK MANAGER, SOLICITOR, ACCOUNTANT OR OTHER
INDEPENDENT FINANCIAL ADVISER DULY AUTHORISED UNDER THE FINANCIAL SERVICES AND
MARKETS ACT 2000 IF YOU ARE RESIDENT IN THE UNITED KINGDOM, OR, IF NOT, ANOTHER
APPROPRIATELY AUTHORISED INDEPENDENT FINANCIAL ADVISER.

THIS FORM OF ACCEPTANCE SHOULD BE READ IN CONJUNCTION WITH THE ACCOMPANYING
OFFER DOCUMENT DATED 28 MARCH 2002. Unless the context otherwise requires,
definitions contained in the Offer Document also apply in this Form of
Acceptance.

If you have sold or otherwise transferred all of your Innogy Shares, please
forward this Form of Acceptance, together with the accompanying documents as
soon as possible to the purchaser or transferee, or to the bank, stockbroker or
other agent through whom the sale or transfer was effected for onward
transmission to the purchaser or transferee. However, such documents should not
be forwarded or transmitted in or into Australia, Canada or Japan or any other
jurisdiction if to do so would constitute a violation of the relevant laws in
such jurisdictions. See paragraph 6 of Part B of Appendix I to the Offer
Document.

The Offer (including the Loan Note Alternative) is not being made, directly or
indirectly, in or into Australia, Canada or Japan and, subject to certain
exemptions, the Offer is not capable of acceptance from or within Australia,
Canada or Japan. Accordingly, neither this Form of Acceptance nor any of the
accompanying documents is being or may be mailed or otherwise forwarded,
distributed or sent into or from Australia, Canada or Japan and doing so may
render any purported acceptance of the Offer invalid. All holders of Innogy
Shares (including nominees, trustees or custodians) who may have a contractual
or legal obligation, or may otherwise intend, to forward this Form of Acceptance
and/or the accompanying documents, should read the further details in this
regard which are contained in paragraph 6(e) of Part B of Appendix I to the
Offer Document before taking any action.

The Loan Notes to be issued pursuant to the Loan Note Alternative have not been,
and will not be, listed on any stock exchange and have not been and will not be
registered under the US Securities Act or under any relevant securities laws of
any state or other jurisdiction of the United States, or under the relevant
securities laws of Australia, Canada or Japan or any other jurisdiction.
Accordingly, unless an exemption under such relevant laws is available, Loan
Notes may not be offered, sold, re-sold or delivered, directly or indirectly,
in, into or from the United States, Australia, Canada or Japan or any other
jurisdiction in which an offer of Loan Notes would constitute a violation of
relevant laws or require registration of the Loan Notes, or to or for the
account or benefit of any US person or resident of Australia, Canada or Japan or
any other such jurisdiction.

If you are a CREST sponsored member, you should refer to your CREST sponsor

o    To accept the Offer, complete page 3 of this Form of Acceptance by
     following the instructions and notes for guidance set out on pages 2 and 4.
     Please also refer to the document "How to accept the Offer for your Innogy

o    If your Innogy Shares are in certificated form (that is, not in CREST),
     return this Form of Acceptance duly completed and signed and accompanied by
     your certificate(s) and/or other document(s) of title, by post or by hand

     the action set out in paragraph 13 of the letter from Merrill Lynch
     contained in the Offer Document to transfer your Innogy Shares to an escrow

o    If your Innogy Shares are held outside of CREST and your share
     certificate(s) and/or other document(s) of title are with your bank,
     stockbroker or other agent, you should complete and sign this Form of
     Acceptance and arrange for it to be lodged by such agent with the relevant
     document(s).

o    Please read Parts A and B of Appendix I to the Offer Document, the terms of
     which are incorporated in and form part of this Form of Acceptance.

o    If you hold Innogy Shares jointly with others, you must arrange for all
     your co-holders to sign this Form of Acceptance.

o    A Form of Acceptance which is received in an envelope postmarked, or which
     otherwise appears to RWE, or the Offeror or their agents to have been sent
     from Australia, Canada or Japan, may be rejected as an invalid acceptance
     of the Offer.
