Reference Index: points per annum.

The Reference Asset is the Solactive Canadian Large-Cap 100 AR Index which aims to track the gross total return performance of the Solactive Canada Large Cap Index (GTR), calculated in CAD, reduced by an Adjusted Return Factor of 100 index points per annum.

As of May 16, 2023, the dividends and/or distributions paid on account of all of the issuers or constituents of the TR Index represented an annual indicative yield of approximately 3.56%, representing an aggregate yield of approximately 17.80% over the term of the Note Securities, assuming that the dividends and/or distributions remain constant and are not reinvested. An investment in the Note Securities does not represent a direct or indirect investment in the TR Index or any of the constituent securities that comprise the TR Index. Holders have no right or entitlement to the dividends or distributions paid on such securities.

The performance of the Reference Index will vary higher or lower from the performance of the TR Index over the term of the Note Securities depending on whether the impact of the dividends and other distributions reinvested in the TR Index is greater or less than the impact the Adjusted Return Factor has on the Closing Level over the term of the Note Securities.

• Should you have any questions, do not hesitate to contact your advisor.

FUNDSERV CODE: NBC24467

The Closing Level of the Reference Index on May 16, 2023 was 2,452.81. The Adjusted Return Factor divided by the Closing Level of the Reference Index was therefore equal to 4.08% on May 16, 2023. Over the term of the Note Securities, the sum of the Adjusted Return Factor of 100 points per annum will be approximately 500 index points, representing 20.38% of the Closing Level of the Reference Index on May 16, 2023.

• the Note Securities provide no protection for your original principal investment and if the Reference Portfolio Return is lower than the Call Threshold on every Call Valuation Date and is lower than the Barrier on the Final Valuation Date, you will receive an amount which is less than your original principal investment on the Maturity Payment Date;

• your Note Securities will be redeemed automatically prior to the Maturity Date if on any Call Valuation Date the Reference Portfolio Return is equal to or higher than the Call Threshold;

• any positive Reference Portfolio Return in excess of the Variable Return Threshold on either a Call Valuation Date or the Final Valuation Date will be multiplied by a Participation Factor which will result in a Holder receiving less than 100% of that excess amount, as the case may be;

• your investment strategy should be consistent with the investment features of the Note Securities;

• your investment time horizon should correspond with the term of the Note Securities; and

• your investment will be subject to the risk factors summarized in the section “Risk Factors” in the Prospectus Supplement and the Prospectus.

Risk Factors

The Note Securities differ from conventional debt and fixed income investments; repayment of the entire Principal Amount is not guaranteed. The Note Securities entail downside risk and are not designed to be alternatives to conventional debt or fixed income investments or money market instruments.

Investing in the Note Securities involves risks that are described under “Risk Factors” in the Prospectus Supplement and the Prospectus, including, without limitation, the section therein entitled “Certain Risk Factors related to the Index Linked Note Securities”. Purchasers are urged to read the information about these risks, together with the other information in the Pricing Supplement, the Prospectus Supplement and the Prospectus, before investing in the Note Securities. Holders who are not prepared to accept the risks described in the Prospectus Supplement and the Prospectus should not invest in the Note Securities.

Use of the Reference Asset

The Reference Index is the intellectual property (including any registered trademarks) of Solactive AG, which is used under license. The Note Securities are not sponsored, promoted, sold or supported in any other manner by Solactive AG nor does Solactive AG offer any express or implicit guarantee or assurance either with regards to the results of using the Reference Index and/or Reference Index trademark or the Closing Level of the Reference Index at any time or in any other respect.

NOTICE

The Note Securities will not constitute deposits that are insured under the Canada Deposit Insurance Corporation Act or any other deposit insurance regime designed to ensure the payment of all or a portion of a deposit upon insolvency of the deposit taking institution.

Amounts paid to Holders will depend on the performance of the Reference Portfolio. None of the Bank, its affiliates, the Dealers, or any other person or entity guarantees that Holders will receive an amount equal to their original investment in the Note Securities or guarantees that any return will be paid on the Note Securities on a Call Date or at maturity. Since the Note Securities are not protected and the Principal Amount will be at risk (other than the minimum Maturity Redemption Payment of 1% of the Principal Amount), it is possible that Holders could lose some or substantially all of their original investment in the Note Securities.

For the various risks associated with such an investment, please see the “Risk Factors” section of this document and the “Risk Factors” section in the Prospectus Supplement and the Prospectus. Any prospective investor must be able to bear the risks involved and must meet the suitability requirements of the Note Securities. Please see the section “Suitability of the Note Securities for Investors” in the Pricing Supplement and the Prospectus Supplement.
