The Placing announced on 15 May 2018 has closed successfully, resulting in the issue of 66,666,667 new ordinary shares of no par value in the Company at 15 pence per share, raising aggregate gross proceeds for the Company of approximately £10 million.

Voluntary delisting from the Toronto Stock Exchange

The Company also announces that it has applied for a voluntary delisting of its ordinary shares from the Toronto Stock Exchange (“TSX”) in Canada (the “Delisting”). The Company intends to voluntarily delist from the TSX post-market on May 22, 2018, retaining its listings on the Warsaw Stock Exchange and AIM.

The Company believes that the relatively low trading volume of its shares on the TSX over a sustained period no longer justifies the financial and administrative costs associated with maintaining a TSX listing.

Shareholders of the Company (the “Shareholders”) currently hold shares of the Company (the “Shares”) in physical certificated form or through the Canadian Depositary for Securities (“CDS”). Following the Delisting, Shareholders wishing to trade their Shares on AIM will require that such shares are made eligible to be transferred and settled though CREST, the United Kingdom based share transfer and settlement system. Shares cannot be transferred and settled through CREST until a Shareholder’s CDS Participant broker or the Shareholder, if the Shares are held in certificated form, as applicable, validly instructs Computershare Trust Company of Canada (“Computershare”) to arrange for the Shares to be held by a CREST participant broker. This can be done by completing a ‘ Register Removal Request – Canada to Jersey ’ form, with valid CREST participant account details, and submitting such form to Computershare via email at globaltransactionteam@computershare.com .

For any questions on this process please contact Computershare’s global transaction unit by phone at +1 (877) 624-5999. The Company intends to maintain CDS eligibility for its shares until June 29, 2018 in order to allow Shareholders time to complete the process contemplated above.
