            You may wish to consider an investment in the notes if:
           | 
            The notes may not be an appropriate investment for you if:
           | |
| 
              ■   
             
              You anticipate that the value of the Basket on any of the Observation Dates will be equal to or greater than the Starting Value and, in that case, you accept an early exit from your investment.
             
              ■   
             
              You accept that the return on the notes will be limited to the return represented by the applicable Call Premium even if the percentage change in the value of the Basket is significantly greater than the applicable Call Premium.
             
              ■   
             
              If the notes are not called, you accept that your investment will result in a loss, which could be significant, if the Ending Value is below the Threshold Value.
             
              ■   
             
              You are willing to forgo the interest payments that are paid on conventional interest bearing debt securities.
             
              ■   
             
              You are willing to forgo dividends or other benefits of owning the Basket Components or the assets held by the Basket Components.
             
              ■   
             
              You are willing to accept a limited or no market for sales prior to maturity, and understand that the market prices for the notes, if any, will be affected by various factors, including our and BAC's actual and perceived creditworthiness, BAC's internal funding rate and fees and charges on the notes.
             
              ■   
             
              You are willing to assume our credit risk, as issuer of the notes, and BAC's credit risk, as guarantor of the notes, for all payments under the notes, including the Call Amounts and the Redemption Amount.
             | 
              ■   
             
              You wish to make an investment that cannot be automatically called prior to maturity.
             
              ■   
             
              You believe that the notes will not be automatically called and the value of the Basket will decrease from the Starting Value to the Ending Value.
             
              ■   
             
              You anticipate that the Observation Level will be less than the Call Level on each Observation Date.
             
              ■   
             
              You seek an uncapped return on your investment.
             
              ■   
             
              You seek principal repayment or preservation of capital.
             
              ■   
             
              You seek interest payments or other current income on your investment.
             
              ■   
             
              You want to receive dividends or other benefits of owning the Basket Components or the assets held by the Basket Components.
             
              ■   
             
              You seek an investment for which there will be a liquid secondary market.
             
              ■   
             
              You are unwilling or are unable to take market risk on the notes or to take our credit risk as issuer of the notes or to take BAC's credit risk, as guarantor of the notes.

            If the notes are not automatically called, your investment will result in a loss; there is no guaranteed return of principal.
           | 
| 
            ■   
           | 
            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.
           | 
| 
            ■   
           | 
            Payments on the notes are subject to our credit risk, and the credit risk of BAC, and any actual or perceived changes in our or BAC's creditworthiness are expected to affect the value of the notes. If we and BAC become insolvent or are unable to pay our respective obligations, you may lose your entire investment.
           | 
| 
            ■   
           | 
            Your investment return is limited to the return represented by the applicable Call Premium and may be less than a comparable investment directly in the Basket Components or the assets included in the Basket Components.
           | 
| 
            ■   
           | 
            Changes in the prices of the Basket Components may offset each other.

| 
            ■   
           | 
            The initial estimated value of the notes considers certain assumptions and variables and relies in part on certain forecasts about future events, which may prove to be incorrect. The initial estimated value of the notes is an estimate only, determined as of a particular point in time by reference to our and our affiliates' pricing models. These pricing models consider certain assumptions and variables, including our credit spreads and those of BAC, BAC's internal funding rate on the pricing date, mid-market terms on hedging transactions, expectations on interest rates and volatility, price-sensitivity analysis, and the expected term of the notes.  These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect.
           | 
| 
            ■   
           | 
            The public offering price you pay for the notes will exceed the initial estimated value. If you attempt to sell the notes prior to maturity, their market value may be lower than the price you paid for them and lower than the initial estimated value. This is due to, among other things, changes in the value of the Basket, changes in BAC's internal funding rate, and the inclusion in the public offering price of the underwriting discount and the hedging related charge, all as further described in "Structuring the Notes" on page TS-19. These factors, together with various credit, market and economic factors over the term of the notes, are expected to reduce the price at which you may be able to sell the notes in any secondary market and will affect the value of the notes in complex and unpredictable ways.
           | 
| 
            ■   
           | 
            The initial estimated value does not represent a minimum or maximum price at which we, BAC, MLPF&S, BofAS or any of our other affiliates would be willing to purchase your notes in any secondary market (if any exists) at any time. The value of your notes at any time after issuance will vary based on many factors that cannot be predicted with accuracy, including the performance of the Basket, our and BAC's creditworthiness and changes in market conditions.
           | 
| 
            ■   
           | 
            A trading market is not expected to develop for the notes. None of us, BAC, MLPF&S or BofAS 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.

           | 
            BAC and its affiliates' hedging and trading activities (including trades in shares of the Basket Components or the assets included in the Basket Components) and any hedging and trading activities BAC or its affiliates engage in that are not for your account or on your behalf, may affect the market value and return of the notes and may create conflicts of interest with you.

            The performance of the Basket Components may not correlate with the performance of the assets held by the Basket Components as well as the net asset value per share of the Basket Components, especially during periods of market volatility when the liquidity and the market price of shares of the Basket Components and/or the assets held by the Basket Components may be adversely affected, sometimes materially.
           | 
| 
            ■

            Risks associated with the Basket Components or the underlying assets of the Basket Components will affect the share price of the Basket Components and hence, the value of the notes.

            The payments on the notes will not be adjusted for all corporate events that could affect the Basket Components. See "Description of the Notes-Anti-Dilution and Discontinuance Adjustments Relating to Underlying Funds" beginning on page PS-32 of the accompanying product supplement.

            There is no statutory, judicial, or administrative authority directly addressing the characterization of the notes.
           | 
| 
            ■   
           | 
            You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the notes for all tax purposes as a callable single financial contract with respect to the Basket.
           | 
| 
            ■   
           | 
            Under this characterization and tax treatment of the notes, a U.S. Holder (as defined on page 71 of the prospectus) generally will recognize capital gain or loss upon maturity or upon a sale, exchange, or redemption of the notes prior to maturity. This capital gain or loss generally will be long-term capital gain or loss if you held the notes for more than one year.
           | 
| 
            ■   
           | 
            No assurance can be given that the Internal Revenue Service ("IRS") or any court will agree with this characterization and tax treatment.
           |

           | 
            Under current IRS guidance, withholding on "dividend equivalent" payments (as discussed in the product supplement), if any, will not apply to notes that are issued as of the date of this term sheet unless such notes are "delta-one" instruments.
