Loan agreement

Proton Power Systems plc (AIM: PPS), the designer, developer and producer of fuel cells and fuel cell electric hybrid systems, announces that it has agreed the terms of a €10.9 million loan (the "Loan") with Roundstone Properties Limited ("Roundstone"). The Loan is repayable on 6 May 2017 and is on the same terms as the loan previously announced on 28 November 2012, including the conversion right of the interest payable on the Loan, and will be used to satisfy the Company's working capital needs.

Related Party Transaction

Roundstone is a company connected to Dr. Faiz Nahab, the Chief Executive Officer of the Company, and is also a substantial shareholder (as defined in the AIM Rules) of the Company. Entering into the agreement in relation to the Loan with Roundstone is therefore classified as a transaction with a related party for the purposes of the AIM Rules. In accordance, therefore, with the AIM Rules, the directors of the Company, with the exclusion of Dr. Faiz Nahab, having consulted with the Company's nominated adviser, Westhouse Securities Limited, consider that the terms of the transaction are fair and reasonable in so far as the Company's shareholders are concerned.
