Forward-looking statements: This press release contains certain information that may constitute “forward-looking statements” and “forward looking information” (collectively, “forward-looking statements”) within the meaning of applicable securities laws. Such forward-looking statements include, without limitation, statements evaluating the market, potential demand for stevia and general economic conditions and discussing future-oriented costs and expenditures. Often, but not always, forward-looking statements can be identified by the use of words such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes” or variations of such words and phrases or words and phrases that state or indicate that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved.

While the Company has based these forward-looking statements on its current expectations about future events, the statements are not guarantees of the Company’s future performance and are subject to risks, uncertainties, assumptions and other factors which could cause actual results to differ materially from future results expressed or implied by such forward-looking statements. Such factors include amongst others the effects of general economic conditions, consumer demand for our products and new orders from our customers and distributors, changing foreign exchange rates and actions by government authorities, uncertainties associated with legal proceedings and negotiations, industry supply levels, competitive pricing pressures and misjudgments in the course of preparing forward-looking statements. Specific reference is made to the risks set forth under the heading “Risk Factors” in the Company’s Annual Information Form for the financial year ended December 31, 2010. In light of these factors, the forward-looking events discussed in this press release might not occur.

Further, although the Company has attempted to identify factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

As there can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements, readers should not place undue reliance on forward-looking statements.

Financial outlook information contained in this press release about prospective results of operations, capital expenditures or financial position is based on assumptions about future events, including economic conditions and proposed courses of action, based on management’s assessment of the relevant
