Idox plc (the "Company") announces that 347,561 ordinary shares of 1 pence each ("Ordinary Shares") have been issued and allotted following an exercise of options by an employee and a former employee.

Application has been made to the London Stock Exchange for the Ordinary Shares, which will rank pari passu with the existing shares in issue, to be admitted to trading on AIM and admission is expected to become effective on 29 August 2014.

The Company's total issued share capital after the admission of the new Ordinary Shares will be 358,733,615 Ordinary Shares. The Company holds 2,355,219 Ordinary Shares in treasury. Therefore the total number of Ordinary Shares in issue excluding shares held in treasury is 356,378,396.

The above figure of 356,378,396 Ordinary Shares may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the FCA's Disclosure and Transparency Rules.
