06 January 2006



                                  Dewhurst Plc
                         ('Dewhurst' or 'the Company')

Publication of Circular regarding Acquisition of TMP Limited and Cancellation of
                                    Listing

The Company has today posted a circular to shareholders in relation, inter alia,
to the proposed acquisition of Traffic Management Products Limited, the
cancellation of listing on the Official List and the admission of the Company to
trading on AIM and notice of an Extraordinary General Meeting to be held on 24
January 2006.

The Directors believe that there are a number of benefits for the Company in
transferring its listing to AIM from the Official List. AIM is more appropriate
for a company of Dewhurst's size; it offers the advantage of greater
flexibility, particularly with regard to corporate transactions and related
costs. In addition, there are possible beneficial tax consequences for
individual Shareholders.

The AIM Rules require that the Company appoints a nominated adviser and broker
before its shares are admitted to trading on AIM and Seymour Pierce has agreed
to act in these roles.

The Board is aware that there may be circumstances in which certain Shareholders
may be prohibited from investing in AIM shares: AIM shares are not allowed to be
held in a personal equity plan or an individual savings account. Such
Shareholders are advised to review their position in this respect as soon as
possible and take independent professional advice if necessary.

If the Cancellation is approved, the Company intends to apply for the
cancellation of the listing of its Ordinary Shares and A Non Voting Ordinary
Shares on the Official List to become effective at 7.30 am on 22 February 2006.

Further, application will be made for the Ordinary Shares and A Non Voting
Ordinary Shares to be admitted to trading on AIM and it is expected that
Admission will be effective on 22 February 2006, immediately following the
Cancellation. Shareholders should note that the cancellation of the listing of
the Shares on the Official List requires to be approved at the Extraordinary
General Meeting to be held on 24 January 2006

('FSA') and will shortly be available for inspection at the FSA's Document
Viewing Facility, which is situated at:
