Checkit : Circular and Notice of General Meeting

THIS DOCUMENT IS IMPORTANT AND REQUIRES YOUR IMMEDIATE ATTENTION. If you are in any doubt about the contents of this document or as to what action you should take, you should immediately consult your stockbroker, bank manager, solicitor, accountant or other independent financial adviser duly authorised under the Financial Services and Markets Act 2000 (as amended) if you are a resident of the United Kingdom or, if not, another appropriately authorised independent professional adviser.

The Existing Ordinary Shares are admitted to trading on AIM. 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 United Kingdom Listing Authority. The London Stock Exchange has not itself examined or approved the contents of this document.

If you have sold or otherwise transferred all of your Ordinary Shares, please send this document and the accompanying proxy form as soon as possible to the purchaser or transferee, or to the stockbroker or other agent through whom the sale or transfer was effected for transmission to the purchaser or transferee. If you have sold or otherwise transferred some (but not all) of your Ordinary Shares, please retain these documents and consult the stockbroker or other agent through whom the sale or transfer was effected immediately.

The Placing Shares shall only be available to qualified investors for the purposes of the Prospectus Regulation Rules or otherwise in circumstances not resulting in an offer of transferable securities to the public under section 102B of FSMA. The Placing does not constitute an offer to the public requiring an approved prospectus under section 85 of FSMA and accordingly this document does not constitute a prospectus for the purposes of the Prospectus Regulation Rules of FCA nor does it comprise an admission document prepared in accordance with the AIM Rules. Accordingly, this document has not been approved by or filed with FCA, the London Stock Exchange or any other regulatory authority. This document does not constitute or form part of any offer or invitation to sell or issue, or a solicitation of any offer to acquire, purchase or subscribe for, Ordinary Shares.

Application will be made to the London Stock Exchange for the Placing Shares to be admitted to trading on AIM, subject to the Resolutions being passed at the General Meeting. On the assumption that, inter alia, the Resolutions are passed, it is expected that Admission will occur and dealings will commence in the Placing Shares at 8.00 a.m. on 17 December 2021. The Placing Shares will, when issued, rank pari passu in all respects with the Existing Ordinary Shares, including the right to receive all dividends or other distributions declared, made or paid on or after they are issued.

Without limiting the generality of the foregoing, subject to certain exemptions in accordance with United States federal and applicable state securities laws and pursuant to the US Securities Act, this document does not constitute an offer of Ordinary Shares to any person with a registered address, or who is resident in, the United States, or who is otherwise a "U.S. Person" as defined in Regulation S under the US Securities Act. The Ordinary Shares may not be offered, sold, taken up, resold, transferred or delivered directly or indirectly, within, into or in the United States except pursuant to an applicable exemption from, or in a transaction not subject to,
