Contingent coupons are paid monthly only if the lowest performing underlier on the related calculation day is at or above its coupon threshold (50% of starting value); the contingent coupon rate will be set on the pricing date and will be at least 26.07% per annum. If an automatic call condition is met on specified calculation days, securities will be redeemed early for face amount plus accrued contingent coupons.

The securities are unsecured obligations of Bank of Montreal and carry issuer credit risk and complex tax considerations, including uncertain U.S. federal tax treatment and potential withholding for non-U.S. holders.
