Extension of Repayment Date of Convertible Loan Notes

MALVERN, PENNSYLVANIA, AND STAFFORD, UK, 13 December 2011 - PuriCore (LSE: PURI), the water-based clean technology company focused on developing and commercialising proprietary, green solutions that safely, effectively, and naturally kill infectious pathogens, today announces an extension of the repayment date in relation to the convertible loan notes issued by the Company on 14 June 2010 (the "Convertible Loan Notes"), details of which were announced and set out in a circular to shareholders on 28 May 2010.

Following the announcement on 21 October 2011 that the Company was exploring a number of options regarding the Convertible Loan Notes, PuriCore has reached an agreement with the requisite majority of holders of the Convertible Loan Notes for a two-year extension of the repayment date, which will now be 31 December 2013. The Convertible Loan Notes, amounting to £7.95 million, were due to be repaid on 31 December 2011, subject to the holders having the right to convert all or part of their holdings into ordinary shares of the Company at a price (following the consolidation of the share capital on 14 June 2010) of 75p per share. There have otherwise been no other changes to the terms of the Convertible Loan Notes.

The Company is currently negotiating additional funding lines and is considering raising further capital. All new funding will be used for market development and general working capital purposes. Any issue of new equity may be undertaken in conjunction with a renegotiation of the Convertible Loan Notes to include a reduction in the conversion price (if appropriate) to reflect market conditions and to provide an incentive for early conversion. Any significant issue of new equity and proposed changes to the conversion terms of the Convertible Loan Notes will be subject to shareholder approval.
