Confirmation of changes to the concert party

Crimson Tide, the provider of the mpro5 process management app, announces recent changes to the composition of the concert party in respect of the Company.

Under the City Code on Takeovers and Mergers (the "Code") published by the Panel on Takeovers and Mergers (the "Panel"), a concert party arises where persons who, pursuant to an agreement or understanding (whether formal or informal), co-operate to obtain or consolidate control (as defined in the Code) of a company or to frustrate the successful outcome of an offer for a company.

Certain persons will be presumed, as set out in the Definitions in the Code, to be persons acting in concert with other persons in the same category unless the contrary is established, including shareholders in a private company who sell their shares or interests in consideration for the issue of new shares in a company to which the Code applies, or who, in connection with an initial public offering or otherwise, become shareholders in a company to which the Code applies.

At the time of its admission to AIM on 22 August 2006, the Company stated in its AIM Admission Document that it had agreed with the Panel that a concert party existed in the context of the Company (the "IPO Concert Party") which held approximately 76% of the Company's issued share capital. Material developments since that time have prompted a review of the IPO concert party, including a share consolidation; the deaths of several IPO Concert Party members; and the disassociation of certain IPO Concert Party members.

Accordingly, the Company has now agreed with the Panel that the IPO Concert Party is now comprised of the following members, who together hold approximately 19.96% of the Company's issued share capital:

Under Rule 9 of the Code, any person who acquires an interest in shares which, taken together with shares in which that person or any person acting in concert with that person is interested, carry 30% or more of the voting rights of a company which is subject to the Code is normally required to make an offer to all the remaining shareholders to acquire their shares.
