AND WHEREAS effective February 4, 2010, Gold Wheaton Gold Corp. consolidated the GW Common Shares on the basis of ten pre-consolidation GW Common Shares for each one post-consolidation GW Common Share (the “Consolidation”);

AND WHEREAS in connection with the Consolidation, Gold Wheaton Gold Corp. entered into a supplemental warrant indenture dated as of February 4, 2010 (together with the Original Warrant Indenture, the “Indenture”) with the Warrant Agent which amended the Original Warrant Indenture so as to provide that a total of 14,375,000 Warrants are created and authorized to be issued under the Indenture, each whole Warrant exercisable to acquire one post-consolidation GW Common Share at an exercise price of $5.00 per GW Common Share at any time prior to 5:00 p.m. (Vancouver time) on the fifth anniversary of the date of issuance;
