Enclosure:   Announcement dated January 10, 2005: Avecia Group plc Announces
Revised Price Range Relating to its Offer to Purchase for Cash Outstanding 11%
Senior Notes Due July 1, 2009

================================================================================




This announcement is neither an offer to purchase nor a solicitation of an offer
to sell any securities. The offer described below is made only pursuant to the
Offer Document (as defined below) in those jurisdictions where the securities or
other laws require the offer to be made on behalf of the Company (as defined
below) by the dealer manager or one or more brokers or dealers licensed or
registered under the laws of such jurisdiction. Holders of Notes (as defined
below) should seek advice from an independent financial adviser as to whether
they should tender Notes.

                 AVECIA GROUP PLC ANNOUNCES REVISED PRICE RANGE
                   RELATING TO ITS OFFER TO PURCHASE FOR CASH
                 OUTSTANDING 11% SENIOR NOTES DUE JULY 1, 2009

     REG S NOTES (CUSIP G9894BAA6 AND ISIN USG9894BAA64), 144A NOTES (CUSIP
     988788AA3 AND COMMON CODE 9875069) REGISTERED NOTES (CUSIP 05354RAA9,
                   ISIN US05354RAA95, COMMON CODE 010588502)

JANUARY 10, 2005 - In connection with its previously announced cash tender offer
(the "Tender Offer") and solicitation of related consents (the "Consent
Solicitation" and, together with the Tender Offer, the "Offer") relating to its
outstanding 11% Senior Notes due July 1, 2009 (the "Notes"), Avecia Group plc
(the "Company"), today announced that it has revised the Maximum Offer Price and
Minimum Offer Price relating to the Tender Offer.

All capitalized terms not defined herein have the meanings ascribed to them in
the Offer Document (as defined below).

The Maximum Offer Price has been raised from US$990.00 to US$1,045.00 per
US$1,000.00 principal amount of the Notes. The Minimum Offer Price has been
raised from US$861.00 to US$980.00 per US$1,000.00 principal amount of the Notes

The Consent Payment in an amount equal to US$10.00 per US$1,000.00 principal
amount of Notes that will be paid to all holders of Notes who validly tender and
do not validly withdraw their Notes and deliver Consents to the Proposed
Amendments prior to the Consent Payment Deadline, regardless of whether such
tendered Notes are accepted for purchase pursuant to the terms of the Offer,
remains unchanged.

The time by which holders of Notes must tender their Notes in order to be
eligible to receive the Clearing Price and the Consent Payment (together, the
"Total Consideration") is prior to 5:00 p.m. New York time, on January 18, 2005,
unless extended (such time and date as the same may be extended, the "Consent
Payment Deadline"). Holders of Notes who desire to receive the Total
Consideration must validly consent to the Proposed Amendments by validly
tendering their Notes in accordance with the requirements of the Depository
Trust Company, on or prior to the Consent Payment Deadline and must have such
tendered Notes accepted for purchase pursuant to the terms of the Offer. Holders
who tender their Notes after the Consent Payment Deadline will be eligible to
receive only the Clearing Price.

The Offer expires at 5:00 p.m., New York time, on February 1, 2005 (such time
and date as the same may be extended, the "Expiration Time"), unless extended or
earlier terminated by the Company by press release or notice to the Tender Agent
in the manner provided in the Offer to Purchase and Consent Solicitation
Statement dated as of January 4, 2005 (the "Offer Document"). If the Offer is
consummated, the settlement date will be on a date




promptly after the acceptance by the Company of tendered Notes. The Company
expects the settlement date (subject to any extension thereof) to be February 4,
2005.

As set forth in the Offer to Purchase, the Company does not yet have the
financial resources to pay for the Notes tendered in the Offer. The Company's
ability to purchase the Notes pursuant to the Offer is dependent on the Company
receiving the proceeds from the consummation of the sale of its NeoResins
business to Koninklijke DSM N.V. (the "Transaction"). The receipt of such
proceeds is conditional, inter alia, upon receipt by the Company of the
Requisite Consents. The consummation of the Transaction is also dependent on
receiving certain approvals and other closing conditions. Any proceeds of the
Transaction will be received by the Company in Euros, while the Offer
consideration will be paid in U.S. dollars. The Company has not hedged, nor does
it intend to hedge, the currency exchange risks it faces with regard to the
Offer, or the repayment of its credit facilities, which credit facilities are
denominated in Pounds Sterling. The Company may therefore be required to amend
the Offer as a result of changes in exchange rates and their impact on the funds
of the Company required to repay the credit facilities and available to
consummate the Offer. The Company continues to keep this situation under review,
particularly in light of changes in the Euro / U.S. dollar exchange rate since
the publication of the Offer on January 4, 2005.

The Offer is being made solely pursuant to the Offer Document which, among other
things, (a) more fully sets forth and governs the terms and conditions of the
Offer, (b) contains additional information about the terms of the Offer, (c)
sets forth how to tender Notes and deliver Consents and (d) contains the
conditions to the Offer.

The Offer Document contains important information that should be read carefully
before any decision is made with respect to the Offer. In deciding whether to
participate in the Offer, each holder should carefully consider the factors set
forth under "Risks to Non-Tendering Holders" and "Risks to Tendering Holders" in
the Offer Document.

Goldman, Sachs & Co. is acting as the exclusive dealer manager for the Offer.
The tender agent for the Offer is Bondholder Services Corporation and the
Luxembourg tender agent for the Offer is Kredietbank S.A. Luxembourgeoise
(together, the "Tender Agents").

Copies of the Offer Document can be obtained (as well as information about the
terms of the Offer, how to tender Notes and the conditions to the Offer) by
contacting Goldman, Sachs & Co. at 85 Broad Street, New York, New York 10004,

(as well as information about the terms of the Offer, how to tender Notes and
the conditions to the Offer) may also be obtained from the Tender Agents, Global

Luxembourgeoise, at 43 Boulevard Royal, L-2955 Luxembourg, Attn: Cecilia
Guichart, Corporate Trust and Agencies Department, +352 47 97 39 35.

This announcement does not constitute a recommendation regarding the Offer.
Holders should seek advice from an independent financial adviser as to the
suitability of the transactions described herein for the individual concerned.

UNDER NO CIRCUMSTANCES SHALL THIS NOTICE CONSTITUTE AN INVITATION OR OFFER TO
SELL OR THE SOLICITATION OF AN INVITATION OR OFFER TO BUY THE NOTES.




THIS COMMUNICATION IS ONLY FOR CIRCULATION TO HOLDERS OF THE NOTES AND TO OTHER
PERSONS TO WHOM IT MAY LAWFULLY BE ISSUED IN ACCORDANCE WITH THE FINANCIAL
