Avisen plc (AIM: AVI)

("Avisen", "the Group" or "the Company")

Result of General Meeting

The directors of Avisen are pleased to announce that further to the Company's announcement on 7 October 2011 regarding Avisen's proposed acquisition of 1Spatial Holdings Plc ("1Spatial") (the "Proposed Acquisition"), all resolutions at the General Meeting ("GM") held earlier today were duly passed. The Proposed Acquisition, which remains subject to certain other conditions, was conditional upon the passing of the resolutions at the GM.

Next Steps

Completion of the Scheme remains subject to the satisfaction or, if permitted, waiver of the remaining conditions of the Scheme set out in the Scheme Document dated 13 October 2011 (the "Scheme Document") including, inter alia, the sanction of the Scheme by the Court, expected to take place on 23 November 2011, and the Reduction of Capital expected to take place on 25 November 2011.

It is expected that the last day for dealings in 1Spatial Shares will be 24 November 2011 and that the Scheme will become effective on 25 November 2011. If the Scheme becomes effective on 25 November 2011, it is expected that the admission to trading on AIM of the 1Spatial Shares will be cancelled at 7.00 am on 28 November 2011 or shortly thereafter. The new Avisen Shares to be allotted to existing 1Spatial Shareholders pursuant to the Scheme will be admitted to trading on AIM on the 28 November 2011.

Unless otherwise stated, all references to time in this announcement are to London time. The dates in this announcement are indicative only. These dates depend on, inter alia, the date upon which the Court sanctions the Scheme and confirms the associated Reduction of Capital, and the date on which the Court Order is delivered to the Registrar and whether the Conditions are satisfied or, (if capable of waiver) waived. Further announcements will be made in due course.

Capitalised terms in this announcement shall have the same meaning as set out in the Scheme Document.

In accordance with Rule 19.11 of the City Code, a copy of this announcement will be made available on the Company's website at www.avisenplc.com and 1Spatials's website at www.1spatial.com.

An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any paper offeror(s).
