4) About the GXG Exchange

GXG Markets operates an European Regulated Market and Multilateral Trading Facility (“MTF”). All shares trading on GXG Markets takes place through GXG’s proprietary electronic trading platform that provides regulated brokers with direct market access so that brokers can:

– see the order book for each security, for both the prices and volumes available;

– place orders to buy and sell at prices and volumes that suit their investors; and – report trades that have been agreed with their clients.

The Directors believe that by providing direct market access, GXG Markets offer a more transparent trading model with prices set by the last traded price rather than by a market maker. This, they believe, delivers faster trade reporting and eliminates spreads between the price a buyer pays and the price a seller obtains.

Commenting on the Admission, Brian McDonnell said ‘We are delighted to be trading on the GXG MTF Market as the shares will now be available to a wider range of potential investors. We are also pleased to be working with Alexander David Securities as our Corporate Advisor, and look forward with them to the next stage in the company’s development.’

(1) Renamed Proventus Renewables plc, following the reverse takeover completed on 23 May 2012.
