Dear Sirs

Enclosed are amended notifications of disclosable interests under the U.K.
Companies Act 1985. Please note that while this information details the
disclosable interests of more than one entity, the enclosed disclosure
constitutes separate notifications of interest which have been combined solely
for purposes of clarity and efficiency. It is not intended to indicate that any
of these entities act as a group or in concert with respect to these interests.

These disclosures are made in the interest of conformity with the Companies Act.
The Interest detailed herein was acquired solely for investment purposes. For
disclosure purposes, holdings should be represented as Fidelity International
Limited (FIL) and its direct and indirect subsidiaries, both being
non-beneficial holders.

 3. The notifiable interests also comprise the notifiable interest of:

    Mr. Edward C. Johnson 3d

    82 Devonshire Street

    Boston, MA 02109

    A principal shareholder of FMR Corp. and Fidelity International Limited.
 4. The notifiable interests include interest held on behalf of authorized unit
    trust schemes in the U.K., notwithstanding the exemption from reporting
    pursuant to Section 209 (1)(h) of the Companies Act 1985.
 5. These notifications of disclosable interests constitute separate
    notifications of interest in the shares and are combined solely for the
    purposes of clarity and efficiency. Nothing herein should be taken to
    indicate that FMR Corp. and its direct and indirect subsidiaries, Fidelity
    International Limited and its direct and indirect subsidiaries or Mr. Edward
    C. Johnson 3d act as a group or in concert in respect of the disclosed
    interests, or that they are required to submit these notifications on a
    joint basis.
 6. The disclosable interests arise under section 208 (4)(b) of the Act, namely
    where a person, not being the registered holder, is entitled to exercise a
    right conferred by the holding of the shares or to control the exercise of
    such rights, or under section 203 of the Act respectively.
 7. Inasmuch as there is no disclosable interest of 3% or greater of the share
    capital, FMR Corp. and its direct and indirect subsidiaries, and Fidelity
    International Limited and its direct and indirect subsidiaries have no
    further reporting obligation under Section 198 to 202 of the UK Companies
    Act. This statement speaks as of its date, and no inference should be drawn
    that no change has occurred in the facts set forth herein after the date
