("VA5"), Venrock Partners V, L.P. ("VP5") and Venrock Entrepreneurs Fund V, L.P. ("VEF5") purchased an aggregate of 110,000,000 shares of the Issuer's common shares. On October 27, 2008, the Issuer filed Articles of Amendment with Industry Canada, under the Canada Business Corporations Act, to effect a one-for-thirty reverse stock split and commenced trading on the NASDAQ Capital Market on a post-consolidation basis on October 28, 2008 (the "Reverse Split"). The Reverse Split affected all holders of the Issuer's common shares uniformly. The common shares listed herein are disclosed on a post-consolidation basis.
