Summary

The Accelerated Return Notes® Linked to a Basket of Three Financial Sector Stocks, due May 22, 2020 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the United States, Canada or any other jurisdiction or secured by collateral. The notes are not bail-inable notes (as defined on page S-2 of the prospectus supplement). The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC.  The notes provide you a leveraged return, subject to a cap, if the Ending Value of the Market Measure, which is the basket of three financial sector stocks described below (the “Basket”), is greater than its Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Basket, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Capped Value) are based on our internal funding rate, which is the rate we would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements.  Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging related charge described below, reduced the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes is greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value for the notes. This initial estimated value was determined based on our pricing models, and was based on our internal funding rate on the pricing date, market conditions and other relevant factors existing at that time, and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-15.

The terms and risks of the notes are contained in this term sheet and in the following:

Investor Considerations

We urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Hypothetical Payout Profile and Examples of Payments at Maturity

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. They illustrate the calculation of the Redemption Amount and total rate of return based on the Starting Value of 100.00, the Participation Rate of 300%, the Capped Value of $12.49 per unit and a range of hypothetical Ending Values. The actual amount you receive and the resulting total rate of return will depend on the actual Ending Value and whether you hold the notes to maturity. The following examples do not take into account any tax consequences from investing in the notes.

For recent hypothetical values of the Basket, see “The Basket” section below. For recent actual prices of the Basket Stocks, see “The Basket Stocks” section below. The Ending Value will not include any income generated by dividends paid on the Basket Stocks, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

(1)       The Starting Value was set to 100.00 on the pricing date.

(2)       The Redemption Amount per unit cannot exceed the Capped Value.

Redemption Amount Calculation Examples

Example 1

The Ending Value is 50.00, or 50.00% of the Starting Value:

Starting Value:     100.00

Ending Value:      50.00

Example 3

The Ending Value is 130.00, or 130.00% of the Starting Value:

Starting Value:     100.00

Ending Value:      130.00

Risk Factors

There are important differences between the notes and a conventional debt security.  An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-6 of product supplement STOCK ARN-1, page S-1 of the prospectus supplement, and page 1 of the prospectus identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

§                  Depending on the performance of the Basket as measured shortly before the maturity date, you may lose up to 100% of the principal amount.

§                  Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

§                  Your investment return is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the Basket Stocks.

§                  Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

§                  Our initial estimated value of the notes is lower than the public offering price of the notes. The public offering price of the notes exceeds our initial estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, all as further described in “Structuring the Notes” on page TS-15, are included in the public offering price of the notes.

§                  Our initial estimated value does not represent future values of the notes and may differ from others’ estimates. Our initial estimated value is only an estimate, which was determined by reference to our internal pricing models when the terms of the notes were set. This estimated value was based on market conditions and other relevant factors existing at that time, our internal funding rate on the pricing date and our assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for the notes that are greater or less than our initial estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the market value of the notes could change significantly based on, among other things, changes in market conditions, including the value of the Market Measure, our creditworthiness, interest rate movements and other relevant factors, which may impact the price at which MLPF&S or any other party would be willing to buy notes from you in any secondary market transactions. Our estimated value does not represent a minimum price at which MLPF&S or any other party would be willing to buy your notes in any secondary market (if any exists) at any time.

§                  Our initial estimated value of the notes was not determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate that was used in the determination of our initial estimated value of the notes generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. If we were to have used the interest rate implied by our conventional fixed-rate debt, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate for market-linked notes had an adverse effect on the economic terms of the notes and the initial estimated value of the notes on the pricing date, and could have an adverse effect on any secondary market prices of the notes.

§                  A trading market is not expected to develop for the notes. Neither we nor MLPF&S is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market. Our business, hedging and trading activities, and those of MLPF&S and our respective affiliates (including trading in shares of the Basket Stocks), and any hedging and trading activities we, MLPF&S or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

§                  None of Citigroup Inc., KeyCorp or Wells Fargo & Company (collectively, the “Underlying Companies”) will have any obligations relating to the notes, and neither we nor MLPF&S will perform any due diligence procedures with respect to the Underlying Companies in connection with this offering.

§                  Changes in the prices of the Basket Stocks may offset each other.

§                  You will have no rights of a holder of the Basket Stocks, and you will not be entitled to receive shares of the Basket Stocks or dividends or other distributions by the Underlying Companies.

§                  While we, MLPF&S or our respective affiliates may from time to time own securities of the Underlying Companies, we, MLPF&S and our respective affiliates do not control any of the Underlying Companies, and have not verified any disclosure made by the Underlying Companies.

§                  The Redemption Amount will not be adjusted for all corporate events that could affect a Basket Stock. See “Description of ARNs—Anti-Dilution Adjustments” beginning on page PS-19 of product supplement STOCK ARN-1.

§                  There may be potential conflicts of interest involving the calculation agent, which is MLPF&S.  We have the right to appoint and remove the calculation agent.

§                  The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes.  See “Summary of U.S. Federal Income Tax Consequences” below and “U.S. Federal Income Tax Summary” beginning on page PS-34 of product supplement STOCK ARN-1.  For a discussion of the Canadian federal income tax consequences of investing in the notes, see “Material Income Tax Consequences—Canadian Taxation” in the prospectus dated March 28, 2017, as supplemented by the discussion under “Summary of Canadian Federal Income Tax Considerations” herein.

Additional Risk Factors

The stocks included in the Basket are concentrated in one sector.  All of the stocks included in the Basket are issued by companies in the financial sector. Although an investment in the notes will not give holders any ownership or other direct interests in the Basket Stocks, the return on an investment in the notes will be subject to certain risks associated with a direct equity investment in companies in the financial services sector. Accordingly, by investing in the notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

Adverse conditions in the financial sector may reduce your return on the notes.  All of the Basket Stocks are issued by companies whose primary lines of business are directly associated with the financial services sector. The profitability of these companies is largely dependent on the availability and cost of capital funds, and can fluctuate significantly, particularly when market interest rates change. Credit losses resulting from financial difficulties of these companies’ customers can negatively impact the sector. In addition, adverse economic, business, or political developments affecting the U.S., including with respect to the insurance sector, or to real estate and loans secured by real estate, could have a major effect on the value of the Basket. As a result of these factors, the value of the notes may be subject to greater volatility and be more adversely affected by economic, political, or regulatory events relating to the financial services sector.

Economic conditions have adversely impacted the stock prices of many companies in the financial services sector, and may do so during the term of the notes.  In recent years, economic conditions in the U.S. have resulted, and may continue to result, in significant losses among many companies that operate in the financial services sector. These conditions have also resulted, and may continue to result, in a high degree of volatility in the stock prices of financial institutions, and substantial fluctuations in the profitability of these companies. Numerous financial services companies have experienced substantial decreases in the value of their assets, taken action to raise capital (including the issuance of debt or equity securities), or even ceased operations. Further, companies in the financial services sector have been subject to unprecedented government actions and regulation, which may limit the scope of their operations and, in turn, result in a decrease in value of these companies. Any of these factors may have an adverse impact on the performance of the Basket. As a result, the value of the Basket may be adversely affected by economic, political, or regulatory events affecting the financial services sector or one of the sub-sectors of the financial services sector. This in turn could adversely impact the market value of the notes and decrease the Redemption Amount.

The Basket

The Basket is designed to allow investors to participate in the percentage changes of the Basket from the Starting Value to the Ending Value. The Basket Stocks are described in the section entitled “The Basket Stocks” below. Each Basket Stock was assigned an initial weight on the pricing date, as set forth in the table below.

For more information on the calculation of the value of the Basket, please see the section entitled “Description of ARNs—Basket Market Measures” beginning on page PS-25 of product supplement STOCK ARN-1.

On the pricing date, for each Basket Stock, the Initial Component Weight, the Closing Market Price, the Component Ratio and the initial contribution to the Basket value were as follows:

(1)         These were the Closing Market Prices of the Basket Stocks on the pricing date.

(2)         Each Component Ratio equals the Initial Component Weight of the relevant Basket Stock (as a percentage) multiplied by 100, and then divided by the Closing Market Price of that Basket Stock on the pricing date and rounded to eight decimal places.

The calculation agent will calculate the Ending Value of the Basket by summing the products of the Closing Market Price for each Basket Stock (multiplied by its Price Multiplier) on the calculation day and the Component Ratio applicable to that Basket Stock. The Price Multiplier for each Basket Stock will initially be 1, and is subject to adjustment as described in product supplement STOCK ARN-1. If a Market Disruption Event occurs as to any Basket Stock on the scheduled calculation day, the Closing Market Price of that Basket Stock will be determined as more fully described in the section entitled “Description of ARNs—Basket Market Measures—Ending Value of the Basket” beginning on page PS-26 of product supplement STOCK ARN-1.

While actual historical information on the Basket did not exist before the pricing date, the following graph sets forth the hypothetical historical daily performance of the Basket from January 1, 2008 through March 28, 2019. The graph is based upon actual daily historical prices of the Basket Stocks, hypothetical Component Ratios based on the closing prices of the Basket Stocks as of December 31, 2007, and a Basket value of 100.00 as of that date. This hypothetical historical data on the Basket is not necessarily indicative of the future performance of the Basket or what the value of the notes may be. Any hypothetical historical upward or downward trend in the value of the Basket during any period set forth below is not an indication that the value of the Basket is more or less likely to increase or decrease at any time over the term of the notes.

Hypothetical Performance of the Basket

The Basket Stocks

We have derived the following information from publicly available documents. We have not independently verified the accuracy or completeness of the following information.

Because each Basket Stock is registered under the Securities Exchange Act of 1934, each Underlying Company is required to file periodically certain financial and other information specified by the SEC. Information provided to or filed with the SEC by the Underlying Companies can be located at the Public Reference Section of the SEC, 100 F Street, N.E., Room 1580, Washington, D.C. 20549 or through the SEC’s website at http://www.sec.gov by reference to the applicable CIK number set forth below.

This term sheet relates only to the notes and does not relate to any securities of the Underlying Companies. Neither we nor any of our affiliates have participated or will participate in the preparation of the Underlying Companies’ publicly available documents. Neither we nor any of our affiliates have made any due diligence inquiry with respect to the Underlying Companies in connection with the offering of the notes. None of us, MLPF&S or any of our affiliates makes any representation that the publicly available documents or any other publicly available information regarding the Underlying Companies are accurate or complete. Furthermore, there can be no assurance that all events occurring prior to the date of this term sheet, including events that would affect the accuracy or completeness of these publicly available documents that would affect the trading price of the Basket Stocks, have been or will be publicly disclosed. Subsequent disclosure of any events or the disclosure of or failure to disclose material future events concerning the Underlying Companies could affect the value of the Basket Stocks and therefore could affect your return on the notes. Information from outside sources is not incorporated by reference in, and should not be considered part of, this term sheet or any accompanying prospectus, prospectus supplement or product supplement. The selection of the Basket Stocks is not a recommendation to buy or sell shares of the Basket Stocks.

The tables set forth below show the quarterly high and low Closing Market Prices of the shares of the Basket Stocks on their primary exchange from the first quarter of 2008 through the pricing date.  We obtained this historical data from Bloomberg L.P.  We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. These historical trading prices may have been adjusted to reflect certain corporate actions such as stock splits and reverse stock splits.

Supplement to the Plan of Distribution

Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

We will deliver the notes against payment therefor in New York, New York on a date that is greater than two business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than two business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S acting as a principal in effecting the transaction for your account.

MLPF&S may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these prices will include MLPF&S’s trading commissions and mark-ups. MLPF&S may act as principal or agent in these market-making transactions; however, it is not obligated to engage in any such transactions. At MLPF&S’s discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes. Any price offered by MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Basket and the remaining term of the notes. However, none of us, MLPF&S, or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

The value of the notes shown on your account statement will be based on MLPF&S’s estimate of the value of the notes if MLPF&S or another of its affiliates were to make a market in the notes, which it is not obligated to do. That estimate will be based upon the price that MLPF&S may pay for the notes in light of then-prevailing market conditions, and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding CIBC or for any purpose other than that described in the immediately preceding sentence.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Basket. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. The internal funding rate we use in pricing the market-linked notes is typically lower than the rate we would pay when we issue conventional fixed-rate debt securities of comparable maturity. This difference is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. This generally relatively lower internal funding rate, which is reflected in the economic terms of the notes, along with the fees and charges associated with market-linked notes, resulted in the initial estimated value of the notes on the pricing date being less than their public offering price.

At maturity, we are required to pay the Redemption Amount to holders of the notes, which will be calculated based on the performance of the Basket and the $10 per unit principal amount. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with MLPF&S or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including MLPF&S and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Basket Stocks, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

MLPF&S has advised us that the hedging arrangements will include a hedging related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to MLPF&S from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by MLPF&S or any third party hedge providers.

For further information, see “Risk Factors—General Risks Relating to ARNs” beginning on page PS-6 and “Use of Proceeds and Hedging” on page PS-15 of product supplement STOCK ARN-1.

MLPF&S Reorganization

The current business of MLPF&S is being reorganized into two affiliated broker-dealers: MLPF&S and a new broker-dealer, BofA Securities, Inc. (“BofAS”). MLPF&S will be assigning its rights and obligations as agent for the notes under our distribution agreement to BofAS effective on the “Transfer Date”. Effective on the Transfer Date, BofAS will be the new legal entity for the institutional services that are now provided by MLPF&S. As such, beginning on the Transfer Date, the institutional services currently being provided by MLPF&S, including acting as agent for the notes, acting as calculation agent for the notes, acting as principal or agent in secondary market-making transactions for the notes and entering into hedging arrangements with respect to the notes, are expected to be provided by BofAS. Accordingly, references to MLPF&S in this term sheet as such references relate to MLPF&S’s institutional services, such as those described above, should be read as references to BofAS to the extent these services are to be performed on or after the Transfer Date.

Summary of Canadian Federal Income Tax Considerations

In the opinion of Blake, Cassels & Graydon LLP, our Canadian tax counsel, the following summary describes the principal Canadian federal income tax considerations under the Income Tax Act (Canada) (the “Canadian Tax Act”) generally applicable at the date hereof to a purchaser who acquires beneficial ownership of a note pursuant to this term sheet and who for the purposes of the Canadian Tax Act and the regulations thereto and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with CIBC and any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the note; (c) does not use or hold and is not deemed to use or hold the note in, or in the course of, carrying on a business in Canada; (d) is entitled to receive all payments (including any interest and principal) made on the note; and (e) is not a, and deals at arm’s length with any, “specified shareholder” of CIBC for purposes of the thin capitalization rules in the Canadian Tax Act (a “Non-Resident Holder”).  A “specified shareholder” for these purposes generally includes a person who (either alone or together with persons with whom that person is not dealing at arm’s length for the purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own 25% or more of CIBC’s shares determined on a votes or fair market value basis.  Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning notes under “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

Based on Canadian tax counsel’s understanding of the Canada Revenue Agency’s administrative policies and having regard to the terms of the notes, interest payable on the notes should not be considered to be “participating debt interest” as defined in the Canadian Tax Act and accordingly, a Non-Resident Holder should not be subject to Canadian non-resident withholding tax in respect of amounts paid or credited or deemed to have been paid or credited by CIBC on a note as, on account of or in lieu of payment of, or in satisfaction of, interest.

Non-Resident Holders should consult their own tax advisors regarding the consequences to them of a disposition of the notes to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.

Summary of U.S. Federal Income Tax Consequences

The following discussion is a brief summary of the material U.S. federal income consequences relating to an investment in the notes.  The following summary is not complete and is both qualified and supplemented by, or in some cases supplements, the discussion entitled “U.S. Federal Income Tax Summary” beginning on page PS-34 of product supplement STOCK ARN-1, which you should carefully review prior to investing in the notes.

The U.S. federal income tax consequences of your investment in the notes are uncertain. No statutory, judicial or administrative authority directly discusses how the notes should be treated for U.S. federal income tax purposes. In the opinion of our tax counsel, Mayer Brown LLP, it would generally be reasonable to treat the notes as prepaid cash-settled derivative contracts. Pursuant to the terms of the notes, you agree to treat the notes in this manner for all U.S. federal income tax purposes. If your notes are so treated, you should generally recognize capital gain or loss upon the sale, exchange, redemption or payment on maturity in an amount equal to the difference between the amount you receive at such time and the amount that you paid for your notes. Such gain or loss should generally be long-term capital gain or loss if you have held your notes for more than one year.

The characterization described above is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Thus, it is possible that the IRS would seek to characterize your notes in a manner that results in tax consequences to you that are different from those described above or in the accompanying product supplement. For a more detailed discussion of certain alternative characterizations with respect to your notes and certain other considerations with respect to your investment in the notes, you should consider the discussion set forth in “U.S. Federal Income Tax Summary” of the product supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the notes for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of the notes for U.S. federal income tax purposes. You should also consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

Validity of the Notes

In the opinion of Blake, Cassels & Graydon LLP, as Canadian counsel to CIBC, the issue and sale of the notes has been duly authorized by all necessary corporate action of CIBC in conformity with the indenture, and when the notes have been duly executed, authenticated and issued in accordance with the indenture, the notes will be validly issued and, to the extent validity of the notes is a matter governed by the laws of the Province of Ontario or the federal laws of Canada applicable therein, will be valid obligations of CIBC, subject to applicable bankruptcy, insolvency and other laws of general application affecting creditors’ rights, equitable principles, and subject to limitations as to the currency in which judgments in Canada may be rendered, as prescribed by the Currency Act (Canada). This opinion is given as of the date hereof and is limited to the laws of the Province of Ontario and the federal laws of Canada applicable therein. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and the genuineness of signature, and to such counsel’s reliance on CIBC and other sources as to certain factual matters, all as stated in the opinion letter of such counsel dated February 27, 2017, which has been filed as Exhibit 5.2 to CIBC’s Registration Statement on Form F-3 filed with the SEC on February 27, 2017.

In the opinion of Mayer Brown LLP, when the notes have been duly completed in accordance with the indenture and issued and sold as contemplated by the prospectus supplement and the prospectus, the notes will constitute valid and binding obligations of CIBC, entitled to the benefits of the indenture, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. This opinion is given as of the date hereof and is limited to the laws of the State of New York.

Market-Linked Investments Classification

MLPF&S classifies certain market-linked investments (the “Market-Linked Investments”) into categories, each with different investment characteristics. The following description is meant solely for informational purposes and is not intended to represent any particular Enhanced Return Market-Linked Investment or guarantee any performance.

Enhanced Return Market-Linked Investments are short- to medium-term investments that offer you a way to enhance exposure to a particular market view without taking on a similarly enhanced level of market downside risk. They can be especially effective in a flat to moderately positive market (or, in the case of bearish investments, a flat to moderately negative market). In exchange for the potential to receive better-than market returns on the linked asset, you must generally accept market downside risk and capped upside potential. As these investments are not market downside protected, and do not assure full repayment of principal at maturity, you need to be prepared for the possibility that you may lose all or part of your investment.
