The underwriters have agreed to purchase 114,000,000 units (the “Units”) at a price of US$0.15 per Unit for gross proceeds of approximately US$17.1 million. Each Unit will entitle the holder to acquire, for no additional consideration, one common share (“Common Share”) of Platinum Group Metals and one common share purchase warrant (a “Warrant”) of Platinum Group Metals. Each Warrant will entitle the holder thereof to purchase one Common Share at a price of US$0.17 for a term of 18 months from the date of closing of the Offering.

In addition to the above, the Company granted the underwriters an option, exercisable for a period of 30 days after closing, to purchase additional Units, Common Shares or Warrants, or any combination thereof, equal to up to 15% of the aggregate number of such securities to be sold in the Offering on the same terms and conditions, to cover over-allotment, if any, and for market stabilization purposes.
