Exercise of Options, Movement of Treasury Shares and Total Voting Rights

Idox plc (the "Company") announces that on 23 February 2016, 3,340,354 ordinary shares of 1 pence each ("Ordinary Shares") were allotted following an exercise of options by the Company's former Chairman, Martin Brooks. All of Mr Brooks' outstanding options have now been exercised.

Application will be made to the London Stock Exchange for the 3,340,354 new 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 1 March 2016.

In addition, on 23 February 2016, the Company transferred 25,000 Ordinary Shares out of treasury to satisfy the exercise of options granted to an employee under the terms of the Company's EMI Scheme.

The Company's total issued share capital after the admission of the new Ordinary Shares will be 362,073,969 Ordinary Shares. The Company now holds 3,030,219 Ordinary Shares in treasury. Therefore the total number of Ordinary Shares in issue excluding shares held in treasury is 359,043,750.

The above figure of 359,043,750 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.
