Tersus Energy – update on HT Blade

Tersus Energy Plc (“Tersus”) has been informed of a transaction related to its investment in ZhongHong (Baoding) Huiteng WindPower Equipment Company Ltd (“HT Blade”).

Tersus, the renewable energy company traded on AIM, invested $2 million in February 2006 in a Texan partnership called Tang Wind Energy LP ("TWELP"). This investment acquired a 12.1 per cent. interest in TWELP through a convertible loan note since converted. TWELP's only asset, other than cash, is a 100 per cent. holding in TWELLC, a Cayman Islands corporation. TWELLC's only asset is a 25 per cent. holding in HT Blade. Thus, Tersus indirectly acquired a 3.03 per cent. interest in HT Blade's equity. The implied value of HT Blade's equity at the time of this transaction was, therefore, $66 million.

TWELP recently sold part of its interest in TWELLC. The new investor introduced $20 million, before expenses, and acquired an interest in TWELLC based on a valuation of HT Blade equal to 8 times 2007 post tax profit or 10 times 2007 profit if the option referred to below is exercised. The investor also has an option, until February 2008, to invest a further $20 million into TWELLC at a valuation based on 10 times HT Blade's 2007 profit. This option is exercisable if certain IPO process related milestones are achieved. The percentage interest in TWELLC to be allocated to the new investor will be determined in 2008 based on HT Blade's audited 2007 accounts.

If HT Blade's profit were to be the same in 2007 as it was in 2006 then the HT Blade values implied by the initial investment and the option would be $96m and $120m respectively.
