GLG Life Tech Corporation ("GLG" or the "Company"), the vertically integrated leader in the agricultural and industrial development of stevia extracts, announces that it has received a demand letter from Weider Global Nutrition ("WGN") that states that WGN will commence, on November 4, 2009, legal proceedings in the Supreme Court of British Columbia against the Company. WGN alleges that pursuant to the shareholder agreement between WGN and the Company, GLG Weider Sweet Naturals Corp. ("Sweet Naturals") became the exclusive marketing and sales arm of the Company, except for its Strategic Alliance and Supply Agreement. WGN also alleges misrepresentation and breach of fiduciary duty by the Company. WGN is claiming injunctive relief, an accounting and damages for alleged breaches of the shareholder agreement.

The Company is of the view that the allegations are entirely without merit. The shareholder agreement contemplates the Company's strategic alliance and supply agreement with its key customer and in no way restricts the Company's ability to perform that agreement and pursue any further opportunities arising from that agreement. Further, the shareholder agreement contemplates that marketing and distribution of wholesale stevia extract products through Sweet Naturals is subject to the permission of the Company and that nothing in the agreement prevents the shareholders of Sweet Naturals from competing with Sweet Naturals. The shareholder agreement contemplates that exclusivity for Sweet Naturals is limited to new business actually generated or customers secured by Sweet Naturals. The Company's position is that any claim by WGN for lost profits is expressly excluded under the shareholders' agreement. It is the Company's view that the injunctions and accounting sought are not legally available and the other remedies would not, in any event, materially and adversely effect the business or operations of the Company. The Company will vigorously defend these allegations.

Since the Company is not dependent upon the non-material revenues from Sweet Naturals, Management of the Company reconfirms its financial guidance for 2009 as disclosed in its press release issued October 30, 2009.
