Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the City Code on Takeovers and Mergers, if
any person is, or becomes, 'interested' (directly or indirectly) in 1% or more
of any class of 'relevant securities' of Prudential or of Aviva, all 'dealings'
in any 'relevant securities' of that company (including by means of an option in
respect of, or a derivative referenced to, any such 'relevant securities') must
be publicly disclosed by no later than 3.30 pm (London time) on the London
business day following the date of the relevant transaction.  This requirement
will continue until the date on which any offer becomes, or is declared,
unconditional as to acceptances, lapses or is otherwise withdrawn or on which
the 'offer period' otherwise ends.  If two or more persons act together pursuant
to an agreement or understanding, whether formal or informal, to acquire an '
interest' in 'relevant securities' of Prudential or of Aviva, they will be
deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the City Code, all 'dealings' in 'relevant
securities' of Prudential or of Aviva by Prudential or Aviva, or by any of their
respective 'associates', must be disclosed by no later than 12.00 noon (London
time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose 'relevant
securities' 'dealings' should be disclosed, and the number of such securities in
issue, can be found on the Takeover Panel's website at
www.thetakeoverpanel.org.uk.

'Interests in securities' arise, in summary, when a person has long economic
exposure, whether conditional or absolute, to changes in the price of
securities.  In particular, a person will be treated as having an 'interest' by
virtue of the ownership or control of securities, or by virtue of any option in
respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the City Code, which can also be found
on the Panel's website.  If you are in any doubt as to whether or not you are
required to disclose a 'dealing' under Rule 8, you should consult the Panel.
