The closing of the prospectus offering of debentures is expected to occur prior to the opening of business on Wednesday, July 12, 2017. The debentures will be posted for trading at the opening of business on Wednesday, July 12, 2017, upon confirmation of closing of the offering.

The debentures will not trade or be quoted on an accrued interest basis (they will trade and be quoted on an interest flat basis). All bids, offers and trades in the debentures must reflect both the capital portion of the debentures and all accrued interest. The TSX Venture Exchange will not report accrued interest in regard to any trade in the debentures made through the facilities of the exchange. The debentures, which were issued in the minimum principal amount of $1,000 each, will be quoted based on $1,000 principal amounts with all trades being made in multiples of $1,000 principal amounts (excluding any amount for interest). For example, an order to buy $5,000 principal amount will be given as an order to buy 5,000. An order to sell $20,000 principal amount will be shown as an order to sell 20,000. An order for 1,500, for example, is not acceptable since all trades must be made in multiples of $1,000. The minimum trading unit of debentures is $1,000 principal amount and a board lot of debentures is $1,000 principal amount.
