Dealing disclosure requirements

Under the provisions of Rule 8.3 of the Irish Takeover Rules, if any
person is, or becomes, "interested" (directly or indirectly) in, one
per cent or more of any class of "relevant securities" of
EcoSecurities, all "dealings" in any "relevant securities" of
EcoSecurities (including by means of an option in respect of, or a
derivative referenced to, any such "relevant securities") must be
publicly disclosed by not later than 3.30pm (Dublin time) on the
business day following the date of the relevant transaction.  This
requirement will continue until the date on which the Revised Offer
becomes, or is declared, unconditional as to acceptances or lapses or
is otherwise withdrawn or on which the "offer period" otherwise
ends.  If two or more persons co-operate on the basis of any
agreement, either express or tacit, either oral or written, to
acquire an "interest" in "relevant securities" of EcoSecurities, they
will be deemed to be a single person for the purpose of Rule 8.3 of
the Irish Takeover Rules.

Under the provisions of Rule 8.1 of the Irish Takeover Rules, all
"dealings" in "relevant securities" of EcoSecurities by Carbon
Acquisition Company or EcoSecurities, or by any of their respective
"associates" must also be disclosed by no later than 12 noon (Dublin
time) on the 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 can be found on
the Irish Takeover Panel's website at www.irishtakeoverpanel.ie.

"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 Irish Takeover Rules,
which can also be found on the Irish Takeover Panel's website. If you
are in any doubt as to whether or not you are required to disclose a
dealing under Rule 8, please consult the Irish Takeover Panel's
website at www.irishtakeoverpanel.ie or contact the Irish Takeover
Panel on telephone number [phone]; fax number +353 (0)1
