This document, which comprises an AIM admission document drawn up in accordance with the AIM Rules, has been issued in connection with the application for admission to trading of the Enlarged Share Capital on AIM. This document contains no offer to the public within the meaning of section 102B of FSMA, the Act or otherwise. Accordingly, this document does not comprise a prospectus within the meaning of section 85 of FSMA and has not been drawn up in accordance with the Prospectus Rules or approved by or filed with the Financial Services Authority or any other competent authority. Application will be made for the Enlarged Share Capital to be admitted to trading on AIM, a market operated by the London Stock Exchange. AIM is a market designed primarily for emerging or smaller companies to which a higher investment risk tends to be attached than to larger or more established companies. AIM securities are not admitted to the Official List of the UK Listing Authority. A prospective investor should be aware of the risks of investing in such companies and should make the decision to invest only after careful consideration and, if appropriate, consultation with an independent financial adviser. Each AIM company is required pursuant to the AIM Rules for Companies to have a nominated adviser. The nominated adviser is required to make a declaration to the London Stock Exchange on Admission in the form set out in Schedule Two to the AIM Rules for Nominated Advisers. The London Stock Exchange has not itself examined or approved the contents of this document. The Company, its Directors and the Proposed Directors (whose names and functions appear in paragraph 13 of Part I of this document) accept responsibility for the information contained in this document and for compliance with the AIM Rules for Companies.
