Item 2:	Date of Material Change
	December 18, 2008
Item 3:	News Release
	The news releases were issued at Vancouver, British Columbia on December 18, 2008 and disseminated via PR Newswire.
Item 4:	Summary of Material Change
	The Company announced that the Food and Drug Administration of the United States (“FDA”) confirmed on December 18, 2008 that it had no objection to the conclusion of an independent expert panel which reviewed research on Rebiana and concluded that it is generally recognized as safe for use as a general purpose sweetener, including for use in food and beverages.Rebiana is an all natural, zero calorie sweetener made with 97% Rebaudioside A from the leaves of the stevia plant. The Company also announced that it has completed the necessary work required to declare self-affirmed GRAS status for its RebpureTM product which contains 97% pure Rebaudioside, a stevia extract.
Item 5:	Full Description of Material Change
	5.1          Full Description of Material Change
	The Company announced that the FDA confirmed on December 18, 2008 that it had no objection to the conclusion of an independent expert panel which reviewed research of Rebiana and concluded that it is generally recognized as safe for use (GRAS) as a general purpose sweetener, including for use in food and beverages.Rebiana is an all natural, zero calorie sweetener made with 97% Rebaudioside A from the leaves of the stevia plant. The Company’s strategic partner, Cargill, submitted an application to the FDA for GRAS approval of Rebiana in May of last year. Since then, Rebiana has been under review by the FDA who confirmed that they have no objection to Rebiana being GRAS which will allow the use of Rebiana as a food and beverage ingredient in the U.S.

	The Company has a 10-year renewable strategic alliance and supply agreement with Cargill to provide it with 80% of its global Rebaudioside A extract supply for the first five years of the agreement. The Company’s operations cover each step in the stevia supply chain including seed breeding, propagation, growth and harvest, extraction, refining and distribution of finished product. Cargill has already introduced TRUVIATM, a tabletop product made with Rebiana. A U.S. national marketing campaign has been launched for TRUVIATM, with interest in the market for the zero-calorie sweetener continuing to grow. The Company also announced that it has completed the necessary work required to declare self-affirmed GRAS status for its RebpureTM product which contains 97% pure Rebaudioside, a stevia extract. The RebpureTM GRAS review, which began several months ago, included an extensive review of current research including toxicological data demonstrating the safety of the product. Key to GLG’s self-affirmation, the molecular structure of RebpureTM has been proven to match the molecular structure of Rebiana, which the FDA concluded had been sufficiently documented to receive GRAS approval. As an important step in the GRAS self-affirmation process, GLG worked closely with ChromaDex (CDXC — OTC), a leader in the development of phytochemical and botanical reference standards and the creation of associated intellectual property, to perform a characterization study on GLG’s high grade stevia extract RebpureTM. More specifically, the evaluation showed conclusively that the molecular structures of each product, RebpureTM and Rebiana, were a match. Following GLG’s self-affirmation of GRAS, a notification will be filed with the FDA.
