* The financial terms of the Serica Offer are final and will not be increased or improved except that Serica reserves the right to increase the value of the Serica Offer if (a) there is an announcement on or after the date of this Announcement of an offer or possible offer for Pharos, including a partial offer, or a firm intention to make an offer, by any third party offeror or potential offeror other than Ratio; or (b) the Takeover Panel provides its consent, which will only be given in wholly exceptional circumstances.
