                            Director's Dealing and Loan Back of Monies

The Company has today been informed that Bramley Limited, ("Bramley") a company owned by a discretionary trust of which
Lionel Simons, the Chairman of the Company, and his family, are potential beneficiaries, sold 1,470,000 Ordinary 1p
shares at 17p per share on 13 April 2007, and a further 421,136 Ordinary 1p shares at 20p per share on 16 April 2007.
The sales were made through the market by Falcon Securities, the Company's broker. The gross proceeds of these disposals
total £334,127.

Bramley has in turn agreed to make available a portion of the proceeds of these disposals to the Company by way of a
standby credit facility (the "Facility").  These funds will be used to provide working capital to support the currently
increasing order flow for emission reduction products; Bramley is in discussions with the Company about the exact size
and terms of the Facility, but these will be on arms length, commercial terms.

Following the disposal, Bramley will hold 1,226,511 Ordinary Shares, representing 6.19% of the voting rights of the
Company.  Lionel Simons will now have beneficial interests in a total of 2,226,511 Ordinary Shares, representing 11.24%
of the voting rights of the Company.
