Dear Sirs,
1. All defined terms herein shall have the meanings given in the Company
Support Agreement between Offeror and Offeree dated 28 September 2004
("CSA") unless otherwise defined herein.
2. In consideration of the Offeror agreeing to make the Offer we hereby
irrevocably undertake, represent and warrant to the Offeror as
follows:-
(A) we shall accept or procure acceptance of the Offer in
accordance with its terms in respect of all the Shares held by
the Offeree by not later than 5.00 p.m. California time on the
tenth Business Day after the despatch of the Offer Documents,
and shall forward or procure that there is forwarded, with
such acceptance, the share certificates or other documents of
title in respect of the Shares in accordance with the terms of
the Offer;
(B) we shall not withdraw our acceptance(s) and shall procure that
our acceptance(s) is not withdrawn in respect of all or any of
the Shares;
(C) until the earlier of the First Closing Date or the Expiration
Date the Offeree shall not accept or solicit any exchange
offer commenced by a third party other than Parent or any
Subsidiary of Parent with respect to the Shares.
3. We agree and consent to the deletion of Clause 2 of the CSA
("Irrevocable Undertaking to Accept Offer"), and such Clause 2 shall
forthwith cease to have effect. All other terms of the CSA shall remain
valid and binding.

if we should fail to accept, or procure the acceptance of, the Offer in
accordance with our obligations under this undertaking or should
otherwise be in breach of any of our obligations under this
undertaking, an order of specific performance will be the only adequate
remedy.
6. In the case where the Shares are registered in the name of a nominee,
we shall direct the nominee to act as if the nominee were bound by the
terms of this irrevocable undertaking and we shall use our best
endeavours to do all acts and things necessary to carry the terms
hereof into effect as if we had been the registered holder of the
Offeree Shares registered in the name of such nominee.
7. In the event that the First Closing shall not have taken place before
31 March 2005 this irrevocable undertaking shall automatically lapse
and be of no further force or effect and no party to it shall have any
claim against the other save in respect of any antecedent breach of its
terms.

successors.
