                  Offer declared unconditional in all respects




1.         Offer unconditional in all respects

Persimmon, having received valid acceptances of the Offer in respect of Westbury
Shares representing more than 61 per cent. of Westbury's issued share capital,
announces that the acceptance condition to the Offer has been satisfied. Further
to the announcement on 6 January 2006 that Persimmon Shareholders have approved
the Acquisition and the announcement on 23 December 2005 that the Office of Fair
Trading has decided not to refer the Acquisition to the Competition Commission,
all the conditions of the Offer have now been satisfied and/or waived.
Accordingly, the Offer has been declared unconditional in all respects and will
remain open for acceptance until further notice.

2.         Detailed level of acceptances

As at 3.00 p.m. (London time) on 16 January 2006, valid acceptances of the Offer
had been received in respect of a total of 70,827,883 Westbury Shares,
representing approximately 61.6 per cent. of Westbury's issued share capital.
(Of these valid acceptances, valid elections for the Loan Note Alternative had
been received in respect of a total of 1,960,647 Westbury Shares, representing
approximately 1.7 per cent. of Westbury's issued share capital.) None of these
acceptances were received from persons acting in concert with Persimmon.
Accordingly, the Offer has been declared unconditional as to acceptances.

On 24 November 2005, being the date of the announcement of the Offer, Persimmon
announced that it had received irrevocable undertakings to accept (or procure
the acceptance of) the Offer in respect of a total of 310,951 Westbury Shares,
representing approximately 0.3 per cent. of Westbury's issued share capital.
Valid acceptances have been received in respect of 295,156 of those Westbury
Shares, representing approximately 0.3 per cent. of Westbury's issued share
capital. All of these acceptances are included in the total of valid acceptances
referred to above.

As announced on 24 November 2005, Persimmon acquired 30,000,000 Westbury Shares
thereby increasing its total holding of Westbury Shares to 30,000,001,
representing approximately 26.1 per cent. of Westbury's issued share capital.

Accordingly, as at 3.00 p.m. (London time) on 16 January 2006, Persimmon either
owned or had received valid acceptances in respect of a total of 100,827,884
Westbury Shares representing approximately 87.7 per cent. of Westbury's issued
share capital.

3.         Consideration

Settlement of the consideration due under the Offer will, on or before 30
January 2006, be dispatched by first class post (in the case of holders of

have elected to take up Loan Notes) to or credited to the relevant CREST
accounts (in the case of holders of uncertificated Westbury Shares) of Westbury
Shareholders who have validly accepted the Offer on or before 16 January 2006.

4.         Delisting and Compulsory Acquisition

Application will be made to the Financial Services Authority for the
cancellation of the listing of the Westbury Shares on the Official List and to
the London Stock Exchange for the cancellation of the admission to trading of
Westbury Shares on the London Stock Exchange, with each expected to take effect
from 14 February 2006, being 20 business days following the date of this
announcement.

In addition, if sufficient acceptances are received, Persimmon intends to
implement the procedures set out in sections 428 to 430F (inclusive) of the
Companies Act to acquire compulsorily any Westbury Shares to which the Offer
relates.

Westbury Shareholders who have not yet accepted the Offer and who hold Westbury

Acceptance to Computershare Investor Services PLC as soon as possible. Westbury
Shareholders who have not yet accepted the Offer and who hold Westbury Shares in
uncertificated form are urged to make acceptance electronically through CREST so
that the TTE Instruction settles as soon as possible. Westbury Shareholders who
hold Westbury Shares as a CREST sponsored member, should refer to their CREST
sponsor as only their CREST sponsor will be able to send the necessary TTE
