Buffalo Potash has granted the Lead Agent an over-allotment option, exercisable at any time prior to the Closing Date, to offer up to an additional 15% of the Subscription Receipts at the Offering Prices. The Subscription Receipts will be issued pursuant to a subscription receipt agreement (the “Subscription Receipt Agreement”) to be entered into among Buffalo Potash, the Lead Agent, and the Subscription Receipt Agent. Upon satisfaction of the escrow release conditions (the “Escrow Release Conditions”), which will be further outlined in the Subscription Receipt Agreement, each Subscription Receipt will entitle the holder thereof, without payment of any additional consideration, to one Unit or one FT Share, as applicable. If the Escrow Release Conditions are not satisfied or waived by December 31, 2025, the Subscription Receipts will be cancelled, and the Escrowed Funds, together with any interest earned thereon, will be returned by the Subscription Receipt Agent to subscribers on a pro rata basis.
