The Bank of Nova Scotia

US$1,250,000,000 3.400% SENIOR NOTES DUE 2024 (Bail-inable notes)

* Note: A rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time. Each of the ratings above should be evaluated independently of any other rating.

No PRIIPs KID. Not for retail investors in the EEA.

The Notes are bail-inable debt securities (as defined in the Prospectus) and subject to conversion in whole or in part – by means of a transaction or series of transactions and in one or more steps – into common shares of the Bank or any of its affiliates under subsection 39.2(2.3) of the Canada Deposit Insurance Corporation Act (Canada) (the “CDIC Act”) and to variation or extinguishment in consequence, and subject to the application of the laws of the Province of Ontario and the federal laws of Canada applicable therein in respect of the operation of the CDIC Act with respect to the Notes.

We expect that delivery of the Notes will be made against payment therefor on or about the third Business Day following the Trade Date (this settlement cycle being referred to as “T+3”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two Business Days (“T+2”), unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the Trade Date will be required, by virtue of the fact that each Note initially will settle in three Business Days (T+3), to specify alternative settlement arrangements to prevent a failed settlement.
