to be implemented by means of a Scheme of Arrangement (the "Scheme")

Scheme Effective

The Directors of 1Spatial are pleased to announce that the Scheme of Arrangement under Part 26 of the Companies Act 2006 to implement the recommended acquisition by Avisen of the entire issued share capital of 1Spatial is now effective.

Accordingly, 1Spatial has become a wholly-owned subsidiary of Avisen. Avisen has issued and allotted 5.761 New Avisen Shares for each 1Spatial Share held by 1Spatial Shareholders on the 1Spatial register at 6.00 p.m. on 24 November 2011.

The admission of the 1Spatial Shares to trading on AIM will be cancelled with effect from 7.00 a.m. on 28 November 2011. Application has been made for the admission of 122,069,396 New Avisen Shares to trading on AIM with effect from 8.00 a.m. on 28 November 2011.

Following admission of the New Avisen Shares, which will rank pari passu in all respects with the existing Avisen Shares in issue, Avisen's total issued share capital will comprise 348,769,274 ordinary shares of 1p each. 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, securities of Avisen.

CREST accounts will be credited with New Avisen Shares on 28 November 2011 and share certificates in respect of New Avisen Shares will be despatched no later than 9 December 2011.
