2. 22 Forward-looking statements This presentation and our answers to questions contain statements about expected future events and financial and operating results of BIOX that are forward-looking. By their nature, forward-looking statements require BIOX to make assumptions and are subject to inherent risks and uncertainties. There is significant risk that the forward-looking statements will not prove to be accurate. Readers are cautioned not to place undue reliance on forward-looking statements as a number of factors could cause actual future results and events to differ materially from that expressed in the forward-looking statements. Accordingly, our comments are subject to this disclaimer and qualified by the assumptions, qualifications and risk factors (including those associated with legislation affecting the biodiesel industry, the availability of producer payment programs, and commodity prices) referred to in BIOX’s public disclosure documents filed with Canadian securities regulatory authorities. Except as required by law, BIOX disclaims any intention or obligation to update or revise forward-looking statements.

11. 11 The BIOX multi-feedstock advantage High FFA feedstocks historically trade at 35-40% discount to seed oils impede High levels of FFAs traditional conversion processes 2008 U.S. Biodiesel feedstock sources Low FFA High FFA 17% 26% Other 57% Soy White grease Yellow grease Tallow

13. 13 The impact of our technical advantage CompetitionBIOX Chemistry consumption likely higher Higher priced low FFA feedstock or pretreatment = yield loss Yield: ? 35-40% price discount on higher FFA feedstock Cannot use less chemistry (stoichiometrically) Yield: 1:1 Atmospheric pressure and ambient temperature = low energy cost Energy consumption likely higher BIOX = low cost provider 13

14. 14 Biodiesel directly competes against fossil fuel prices; Many of our competitors sit idle Biodiesel prices based on production costs; BIOX maintains cost advantage The BIOX economic advantage Obligatory (post-mandate)Voluntary (pre-mandate) Biodiesel fixed to diesel price Unprofitable 30% lower cost Traditional (soy feedstock) Biodiesel price BIOX (multi- feed stock) Traditional (soy feedstock) 30% lower cost + industry margin Biodiesel fixed to feedstock price Biodiesel price BIOX (multi- feed stock) 14
