Any capitalized term not defined herein shall have the meaning set forth in the preliminary pricing supplement to which the term sheet relates (se e h yperlink below). 1 SEC File No. 333 - 264388 | May 1, 2024 This term sheet, which gives a brief summary of the terms of the notes, relates to, and should be read in conjunction with, t he pricing supplement dated May 1, 2024, the Product Supplement dated July 7, 2023, the Prospectus Supplement dated May 26, 2022, and to the Prospectus dated May 26, 2022. DATES Offering Period Closes: May 24, 2024 (at 2 pm NY Time.) Pricing Date: On or about May 24, 2024 Settlement Date: On or about May 31, 2024 Valuation Date: On or about May 25, 2027 Maturity Date: On or about May 28, 2027 Term: Approximately 3 Years INVESTMENT OBJECTIVE The objective of the notes is to provide clients the potential for capped leveraged participation in any upside performance o f t he Reference Asset. As such, the notes may be suitable for investors with a bullish view of the Reference Asset over the term of the notes. The performance of the notes ma y n ot be consistent with the investment objective. TERMS Upside Leverage Factor: 150.00% Initial Level: The closing level of the Reference Asset on the Pricing Date. Final Level: The closing level of the Reference Asset on the Valuation Date. Payment at Maturity: If the Final Level of the Reference Asset is greater than its Initial Level and the Percentage Change of the Reference Asset multiplied by the Upside Leverage Factor is greater than or equal to the Maximum Return, the payment at maturity for each $1,000 in principal amount of the notes will equal the Maximum Redemption Amount. If the Final Level of the Reference Asset is greater than its Initial Level and the Percentage Change of the Reference Asset multiplied by the Upside Leverage Factor is less than the Maximum Return, then the amount that investors will receive at maturity for each $1,000 in principal amount of the notes will equal: $1,000 + [$1,000 x (Percentage Change of the Reference Asset x Upside Leverage Factor)] If the Final Level of the Reference Asset is less than or equal to its Initial Level, then investors will, for each $1,000 in principal amount of the notes, receive the principal amount of $1,000 and no additional return. Percentage Change: The Percentage Change of the Reference Asset, expressed as a percentage, is calculated using the following formula: (Final Level – Initial Level) / Initial Level Maximum Return: 30.00% Maximum Redemption Amount: The payment at maturity will not exceed the Maximum Redemption Amount of $1,300.00 per $1,000 in principal amount of the notes. This document amends and restates the free writing prospectus filed April 29, 2024

2 Secondary Market: The notes will not be listed on any securities exchange. Although not obligated to do so, BMO Capital Markets Corp. (or one of its affiliates), plans to maintain a secondary market in the notes after the Settlement Date. Proceeds from a sale of notes prior to maturity may be less than the principal amount initially invested. Selected Risk Considerations: The risks summarized below are some of the most important factors to be considered prior to any purchase of the notes. Investors are urged to read all the risk factors related to the notes in the pricing supplement and the product supplement to which this term sheet relates. • Your return on the notes is limited to the Maximum Redemption Amount, regardless of any appreciation in the levels of the Reference Asset. • Your return on the notes may be lower than the return on a conventional debt security of comparable maturity. • The notes are unsecured debt obligations of the Issuer and your investment is subject to the credit risk of the Issuer. • Our and our affiliates’ activities may conflict with your interests and may also adversely affect the value of the notes. • Our initial estimated value of the notes will be lower than the price to public, does not represent any future value of the notes, and may also differ from the estimated value of any other party. • The terms of the notes are not determined by reference to the credit spreads for our conventional fixed - rate debt. • The inclusion of the hedging profits, if any, in the initial price to public of the notes, as well as our hedging costs, is likely to adversely affect the price at which you can sell your notes. • You will have no right to receive any futures contracts or commodities included in the Reference Asset at maturity. • Changes that affect the Reference Asset will affect the market value of the notes and the amount you will receive at maturity. Adjustments to the Reference Asset could adversely affect the notes. The sponsor of the Reference Asset may make adjustments, discontinue or suspend calculations or publication of the Reference Asset, or discontinue of suspend maintenance of the Reference Asset at any time. • We and our affiliates do not have any affiliation with the sponsor of the Reference Asset and are not responsible for their actions. • The notes will not be listed on any securities exchange. BMOCM may offer to purchase the notes in the secondary market, but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. • The notes could be accelerated upon the occurrence of a commodity hedging disruption event. • The notes will not be regulated by the Commodity Futures Trading Commission. • Prices of futures contracts are characterized by high and unpredictable volatility, which could lead to high and unpredictable volatility in the Reference Asset. • The notes do not offer direct exposure to commodity spot prices. • The prices of commodities are volatile and are affected by numerous factors, certain of which are specific to the commodity sector for each commodity.

3 Hypothetical Calculations for the Payment at Maturity: Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in the notes The following table illustrates the hypothetical payments on a note at maturity. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of 100.00, a hypothetical Upside Leverage Factor of 150.00%, the Maximum Return of 30.00%, the Maximum Redemption Amount of $1,300.00, a range of hypothetical Final Levels and the effect on the payment at maturity. The hypothetical examples shown below are intended to help you understand the terms of the notes. The actual cash amount that you will receive at maturity will depend upon the Final Level of the Reference Asset. These examples do not give effect to any U.S. federal tax payments or brokerage commissions that you may be required to pay in connection with your purchase of the notes.
