Purchase of Shares following Consolidation

26 July 2013

Biome Technologies plc ("Biome", "the Company" or "the Group")

Purchase of Shares following Consolidation

On 23 May 2013, the Company announced a proposed Capital Reduction, Consolidation and Sub-division of its Existing Ordinary Shares which was approved by Shareholders on 20 June.

Further to the Circular sent to Shareholders on 23 May 2013, the Company has now purchased 102,483 New Ordinary Shares of 5p at 85.9p from those Shareholders who held less than 430,000 Existing Ordinary Shares on the Record date, being 15 July 2013. The proceeds of this purchase (net of costs) will be sent to those Shareholders as soon as practicable.

The majority of the New Ordinary Shares bought back will be cancelled. A small number will be held in treasury to satisfy imminent requirements to issue shares. As a result, following the above purchase and cancellation, the Company will have 2,339,794 New Ordinary Shares in Issue, of which 14,545 New Ordinary Shares will be held in treasury. The total number of New Ordinary Shares in issue (excluding shares held as treasury shares) is therefore 2,325,249 (the total number of voting rights in the Company). This figure 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, Biome under the FCA's Disclosure and Transparency Rules

Capitalised terms, unless otherwise defined in this announcement, have the meaning given to them in the Circular.
