The Loan can be drawn down until 31 December 2018 and is repayable in April 2019, it pays an interest of 10 per cent. per annum and the interest, but not the principal, on the loan is payable in new Proton Power ordinary shares at 2p per share at the option of the lender.

The balance of €10.24 million will be used to finance the Company's working capital.

Related Party Transaction

Mr Falih Nahab is indirectly, via Roundstone Properties Limited, a substantial shareholder (as defined in the AIM Rules) of the Company. The entering into the loan agreement with Mr Falih Nahab is therefore classified as a transaction with a related party for the purposes of the AIM Rules.
