Auto Callable Contingent Interest Notes Linked to the Class A Common Stock of Facebook, Inc. due January 17, 2019

Fully and Unconditionally Guaranteed by JPMorgan Chase & Co.

● The notes are designed for investors who seek a Contingent Interest Payment with respect to each Review Date for which the closing price of one share of the Reference Stock is greater than or equal to 70.00% of the Initial Value, which we refer to as the Interest Barrier.

● The earliest date on which an automatic call may be initiated is April 13, 2018.

● Investors in the notes should be willing to accept the risk of losing some or all of their principal and the risk that no Contingent Interest Payment may be made with respect to some or all Review Dates.

Total Contingent Interest Payments

The table below illustrates the hypothetical total Contingent Interest Payments per $1,000 principal amount note over the term of the notes based on a hypothetical Contingent Interest Rate of 6.00% per annum, depending on how many Contingent Interest Payments are made prior to automatic call or maturity. The actual Contingent Interest Rate will be provided in the pricing supplement and will be at least 6.00% per annum.

Number of Contingent Interest Payments	Total Contingent Interest Payments
5	$75.00
4	$60.00
3	$45.00
2	$30.00
1	$15.00
0	$0.00

Hypothetical Payout Examples

The following examples illustrate payments on the notes linked to a hypothetical Reference Stock, assuming a range of performances for the hypothetical Reference Stock on the Review Dates. The hypothetical payments set forth below assume the following:

● an Initial Value of $100.00;

● an Interest Barrier and a Trigger Value of $70.00 (equal to 70.00% of the hypothetical Initial Value); and

● a Contingent Interest Rate of 6.00% per annum (payable at a rate of 1.50% per quarter).

The hypothetical Initial Value of $100.00 has been chosen for illustrative purposes only and may not represent a likely actual Initial Value.

The actual Initial Value will be the closing price of one share of the Reference Stock on the Pricing Date and will be provided in the pricing supplement. For historical data regarding the actual closing prices of one share of the Reference Stock, please see the historical information set forth under “The Reference Stock” in this pricing supplement.

Each hypothetical payment set forth below is for illustrative purposes only and may not be the actual payment applicable to a purchaser of the notes. The numbers appearing in the following examples have been rounded for ease of analysis.

Example 1 — Notes are automatically called on the second Review Date.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$105.00	$15.00
Second Review Date	$110.00	$1,015.00
	Total Payment	$1,030.00 (3.00% return)

Because the closing price of one share of the Reference Stock on the second Review Date is greater than or equal to the Initial Value, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, of $1,015.00 (or $1,000 plus the Contingent Interest Payment applicable to the second Review Date), payable on the applicable Call Settlement Date. The notes are not automatically callable before the second Review Date, even though the closing price of one share of the Reference Stock on the first Review Date is greater than the Initial Value. When added to the Contingent Interest Payment received with respect to the prior Review Date, the total amount paid, for each $1,000 principal amount note, is $1,030.00. No further payments will be made on the notes.

PS-3| Structured Investments Auto Callable Contingent Interest Notes Linked to the Class A Common Stock of Facebook, Inc.

Example 2 — Notes have NOT been automatically called, the Final Value is greater than or equal to the Initial Value and a Trigger Event has occurred.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$95.00	$15.00
Second Review Date	$85.00	$15.00
Third through Fourth Review Dates	Less than Interest Barrier	$0
Final Review Date	$105.00	$1,015.00
	Total Payment	$1,045.00 (4.50% return)

Because the notes have not been automatically called and the Final Value is greater than or equal to the Initial Value (and, therefore, the Interest Barrier), even though a Trigger Event has occurred, the payment at maturity, for each $1,000 principal amount note, will be $1,015.00 (or $1,000 plus the Contingent Interest Payment applicable to the final Review Date). When added to the Contingent Interest Payments received with respect to the prior Review Dates, the total amount paid, for each $1,000 principal amount note, is $1,045.00.

Example 3 — Notes have NOT been automatically called, the Final Value is less than the Initial Value and a Trigger Event has NOT occurred.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$95.00	$15.00
Second Review Date	$95.00	$15.00
Third through Fourth Review Dates	Greater than Interest Barrier	$15.00
Final Review Date	$70.00	$1,015.00
	Total Payment	$1,075.00 (7.50% return)

Because the notes have not been automatically called, the Final Value is greater than or equal to the Interest Barrier and a Trigger Event has not occurred, even though the Final Value is less than the Initial Value, the payment at maturity, for each $1,000 principal amount note, will be $1,015.00 (or $1,000 plus the Contingent Interest Payment applicable to the final Review Date). When added to the Contingent Interest Payments received with respect to the prior Review Dates, the total amount paid, for each $1,000 principal amount note, is $1,075.00.

Example 4 — Notes have NOT been automatically called, the Final Value is less than the Initial Value and the Interest Barrier and a Trigger Event has occurred.

Date	Closing Price	Payment (per $1,000 principal amount note)
First Review Date	$65.00	$0
Second Review Date	$60.00	$0
Third through Fourth Review Dates	Less than Interest Barrier	$0
Final Review Date	$50.00	$500.00
	Total Payment	$500.00 (-50.00% return)

Because the notes have not been automatically called, the Final Value of the Reference Stock is less than the Initial Value and the Interest Barrier, a Trigger Event has occurred and the Stock Return is -50.00%, the payment at maturity will be $500.00 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 × (-50.00%)] = $500.00

The hypothetical returns and hypothetical payments on the notes shown above apply only if you hold the notes for their entire term or until automatically called. These hypotheticals do not reflect the fees or expenses that would be associated with any sale in the secondary market. If these fees and expenses were included, the hypothetical returns and hypothetical payments shown above would likely be lower.

Selected Risk Considerations

An investment in the notes involves significant risks. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement.

● YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS —
The notes do not guarantee any return of principal. If the notes have not been automatically called and (i) the Final Value is less than the Initial Value and (ii) a Trigger Event has occurred, you will lose 1% of the principal amount of your notes for every 1% that the Final Value is less than the Initial Value. Accordingly, under these circumstances, you will lose some or all of your principal amount at maturity.

● THE NOTES DO NOT GUARANTEE THE PAYMENT OF INTEREST AND MAY NOT PAY ANY INTEREST AT ALL —
If the notes have not been automatically called, we will make a Contingent Interest Payment with respect to a Review Date only if the closing price of one share of the Reference Stock on that Review Date is greater than or equal to the Interest Barrier. If the closing price of one share of the Reference Stock on that Review Date is less than the Interest Barrier, no Contingent Interest Payment will be made with respect to that Review Date. Accordingly, if the closing price of one share of the Reference Stock on each Review Date is less than the Interest Barrier, you will not receive any interest payments over the term of the notes.

● CREDIT RISKS OF JPMORGAN FINANCIAL AND JPMORGAN CHASE & CO. —
Investors are dependent on our and JPMorgan Chase & Co.’s ability to pay all amounts due on the notes. Any actual or potential change in our or JPMorgan Chase & Co.’s creditworthiness or credit spreads, as determined by the market for taking that credit risk, is likely to adversely affect the value of the notes. If we and JPMorgan Chase & Co. were to default on our payment obligations, you may not receive any amounts owed to you under the notes and you could lose your entire investment.

● AS A FINANCE SUBSIDIARY, JPMORGAN FINANCIAL HAS NO INDEPENDENT OPERATIONS AND HAS LIMITED ASSETS —
As a finance subsidiary of JPMorgan Chase & Co., we have no independent operations beyond the issuance and administration of our securities. Aside from the initial capital contribution from JPMorgan Chase & Co., substantially all of our assets relate to obligations of our affiliates to make payments under loans made by us or other intercompany agreements. As a result, we are dependent upon payments from our affiliates to meet our obligations under the notes. If these affiliates do not make payments to us and we fail to make payments on the notes, you may have to seek payment under the related guarantee by JPMorgan Chase & Co., and that guarantee will rank pari passu with all other unsecured and unsubordinated obligations of JPMorgan Chase & Co.

● THE APPRECIATION POTENTIAL OF THE NOTES IS LIMITED TO THE SUM OF ANY CONTINGENT INTEREST PAYMENTS THAT MAY BE PAID OVER THE TERM OF THE NOTES,
regardless of any appreciation in the price of the Reference Stock, which may be significant. You will not participate in any appreciation in the price of the Reference Stock.

● POTENTIAL CONFLICTS —
We and our affiliates play a variety of roles in connection with the notes. In performing these duties, our and JPMorgan Chase & Co.’s economic interests are potentially adverse to your interests as an investor in the notes. It is possible that hedging or trading activities of ours or our affiliates in connection with the notes could result in substantial returns for us or our affiliates while the value of the notes declines. Please refer to “Risk Factors — Risks Relating to Conflicts of Interest” in the accompanying product supplement.

● THE BENEFIT PROVIDED BY THE TRIGGER VALUE MAY TERMINATE ON ANY DAY DURING THE MONITORING PERIOD—
If, on any day during the Monitoring Period, the closing price of one share of the Reference Stock is less than the Trigger Value (i.e., a Trigger Event occurs) and the notes have not been automatically called, the benefit provided by the Trigger Value will terminate and you will be fully exposed to any depreciation in the closing price of one share of the Reference Stock. You will be subject to this potential loss of principal even if the Reference Stock subsequently recovers such that the closing price of one share of the Reference Stock is greater than or equal to the Trigger Value.

● THE AUTOMATIC CALL FEATURE MAY FORCE A POTENTIAL EARLY EXIT —
If your notes are automatically called, the term of the notes may be reduced to as short as approximately six months and you will not receive any Contingent Interest Payments after the applicable Call Settlement Date. There is no guarantee that you would be able to reinvest the proceeds from an investment in the notes at a comparable return and/or with a comparable interest rate for a similar level of risk. Even in cases where the notes are called before maturity, you are not entitled to any fees and commissions described on the front cover of this pricing supplement.

● YOU WILL NOT RECEIVE DIVIDENDS ON THE REFERENCE STOCK OR HAVE ANY RIGHTS WITH RESPECT TO THE REFERENCE STOCK.

● NO AFFILIATION WITH THE REFERENCE STOCK ISSUER —
We have not independently verified any of the information about the Reference Stock issuer contained in this pricing supplement. You should undertake your own investigation into the Reference Stock and its issuer. We are not responsible for the Reference Stock issuer’s public disclosure of information, whether contained in SEC filings or otherwise.

● THE ANTI-DILUTION PROTECTION FOR THE REFERENCE STOCK IS LIMITED AND MAY BE DISCRETIONARY —
The calculation agent will not make an adjustment in response to all events that could affect the Reference Stock. The calculation

PS-5| Structured Investments Auto Callable Contingent Interest Notes Linked to the Class A Common Stock of Facebook, Inc.

agent may make adjustments in response to events that are not described in the accompanying product supplement to account for any diluting or concentrative effect, but the calculation agent is under no obligation to do so or to consider your interests as a holder of the notes in making these determinations.

● THE RISK OF THE CLOSING PRICE OF ONE SHARE OF THE REFERENCE STOCK FALLING BELOW THE INTEREST BARRIER OR TRIGGER VALUE IS GREATER IF THE PRICE OF ONE SHARE OF THE REFERENCE STOCK IS VOLATILE.

● LACK OF LIQUIDITY—
The notes will not be listed on any securities exchange. Accordingly, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which JPMS is willing to buy the notes. You may not be able to sell your notes. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

● THE FINAL TERMS AND VALUATION OF THE NOTES WILL BE PROVIDED IN THE PRICING SUPPLEMENT —
You should consider your potential investment in the notes based on the minimums for the estimated value of the notes and the Contingent Interest Rate.

● THE ESTIMATED VALUE OF THE NOTES WILL BE LOWER THAN THE ORIGINAL ISSUE PRICE (PRICE TO PUBLIC) OF THE NOTES —
The estimated value of the notes is only an estimate determined by reference to several factors. The original issue price of the notes will exceed the estimated value of the notes because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include the selling commissions, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. See “The Estimated Value of the Notes” in this pricing supplement.

● THE ESTIMATED VALUE OF THE NOTES DOES NOT REPRESENT FUTURE VALUES OF THE NOTES AND MAY DIFFER FROM OTHERS’ ESTIMATES —
See “The Estimated Value of the Notes” in this pricing supplement.

● THE ESTIMATED VALUE OF THE NOTES IS DERIVED BY REFERENCE TO AN INTERNAL FUNDING RATE —
The internal funding rate used in the determination of the estimated value of the notes is based on, among other things, our and our affiliates’ 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 the conventional fixed-rate debt of JPMorgan Chase & Co. The use of an internal funding rate and any potential changes to that rate may have an adverse effect on the terms of the notes and any secondary market prices of the notes. See “The Estimated Value of the Notes” in this pricing supplement.

● THE VALUE OF THE NOTES AS PUBLISHED BY JPMS (AND WHICH MAY BE REFLECTED ON CUSTOMER ACCOUNT STATEMENTS) MAY BE HIGHER THAN THE THEN-CURRENT ESTIMATED VALUE OF THE NOTES FOR A LIMITED TIME PERIOD —
We generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. See “Secondary Market Prices of the Notes” in this pricing supplement for additional information relating to this initial period. Accordingly, the estimated value of your notes during this initial period may be lower than the value of the notes as published by JPMS (and which may be shown on your customer account statements).

● SECONDARY MARKET PRICES OF THE NOTES WILL LIKELY BE LOWER THAN THE ORIGINAL ISSUE PRICE OF THE NOTES —
Any secondary market prices of the notes will likely be lower than the original issue price of the notes because, among other things, secondary market prices take into account our internal secondary market funding rates for structured debt issuances and, also, because secondary market prices (a) exclude selling commissions and (b) may exclude projected hedging profits, if any, and estimated hedging costs that are included in the original issue price of the notes. As a result, the price, if any, at which JPMS will be willing to buy the notes from you in secondary market transactions, if at all, is likely to be lower than the original issue price. Any sale by you prior to the Maturity Date could result in a substantial loss to you.

● SECONDARY MARKET PRICES OF THE NOTES WILL BE IMPACTED BY MANY ECONOMIC AND MARKET FACTORS —
The secondary market price of the notes during their term will be impacted by a number of economic and market factors, which may either offset or magnify each other, aside from the selling commissions, projected hedging profits, if any, estimated hedging costs and the price of one share of the Reference Stock. Additionally, independent pricing vendors and/or third party broker-dealers may publish a price for the notes, which may also be reflected on customer account statements. This price may be different (higher or lower) than the price of the notes, if any, at which JPMS may be willing to purchase your notes in the secondary market. See “Risk Factors — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement.

Tax Treatment

You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4-I. In determining our reporting responsibilities we intend to treat (i) the notes for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any Contingent Interest Payments as ordinary income, as described in the section entitled “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Prepaid Forward Contracts with Associated Contingent Coupons” in the accompanying product supplement. Based on the advice of Davis Polk & Wardwell LLP, our special tax counsel, we believe that this is a reasonable treatment, but that there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the notes could be materially affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments and the relevance of factors such as the nature of the underlying property to which the instruments are linked. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially affect the tax consequences of an investment in the notes, possibly with retroactive effect. You should consult your tax adviser regarding the U.S.

PS-7| Structured Investments Auto Callable Contingent Interest Notes Linked to the Class A Common Stock of Facebook, Inc.

federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by this notice.

Non-U.S. Holders — Tax Considerations. The U.S. federal income tax treatment of Contingent Interest Payments is uncertain, and although we believe it is reasonable to take a position that Contingent Interest Payments are not subject to U.S. withholding tax (at least if an applicable Form W-8 is provided), a withholding agent may nonetheless withhold on these payments (generally at a rate of 30%, subject to the possible reduction of that rate under an applicable income tax treaty), unless income from your notes is effectively connected with your conduct of a trade or business in the United States (and, if an applicable treaty so requires, attributable to a permanent establishment in the United States). If you are not a United States person, you are urged to consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the notes in light of your particular circumstances.

Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax (unless an income tax treaty applies) on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. Section 871(m) provides certain exceptions to this withholding regime, including for instruments linked to certain broad-based indices that meet requirements set forth in the applicable Treasury regulations (such an index, a “Qualified Index”). Additionally, the applicable regulations exclude from the scope of Section 871(m) instruments issued in 2017 that do not have a delta of one with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on certain determinations made by us, we expect that Section 871(m) will not apply to the notes with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the notes. You should consult your tax adviser regarding the potential application of Section 871(m) to the notes.

FATCA. Withholding under legislation commonly referred to as “FATCA” could apply to payments with respect to the notes that are treated as U.S.-source “fixed or determinable annual or periodical” income (“FDAP Income”) for U.S. federal income tax purposes (such as interest, if the notes are recharacterized, in whole or in part, as debt instruments, or Contingent Interest Payments if they are otherwise treated as FDAP Income). If the notes are recharacterized, in whole or in part, as debt instruments, withholding could also apply to payments of gross proceeds of a taxable disposition, including an early redemption or redemption at maturity. However, under a recent IRS notice, this regime will not apply to payments of gross proceeds (other than any amount treated as FDAP Income) with respect to dispositions occurring before January 1, 2019. You should consult your tax adviser regarding the potential application of FATCA to the notes.

In the event of any withholding on the notes, we will not be required to pay any additional amounts with respect to amounts so withheld.

The Estimated Value of the Notes

The estimated value of the notes set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the notes, valued using the internal funding rate described below, and (2) the derivative or derivatives underlying the economic terms of the notes. The estimated value of the notes does not represent a minimum price at which JPMS would be willing to buy your notes in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the estimated value of the notes is based on, among other things, our and our affiliates’ 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 the conventional fixed-rate debt of JPMorgan Chase & Co. For additional information, see “Selected Risk Considerations — The Estimated Value of the Notes Is Derived by Reference to an Internal Funding Rate” in this pricing supplement.

The value of the derivative or derivatives underlying the economic terms of the notes is derived from internal pricing models of our affiliates. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, the estimated value of the notes is determined when the terms of the notes are set based on market conditions and other relevant factors and assumptions existing at that time.

The estimated value of the notes does not represent future values of the notes and may differ from others’ estimates. Different pricing models and assumptions could provide valuations for the notes that are greater than or less than the estimated value of the notes. 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 value of the notes could change significantly based on, among other things, changes in market conditions, our or JPMorgan Chase & Co.’s creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which JPMS would be willing to buy notes from you in secondary market transactions.

The estimated value of the notes will be lower than the original issue price of the notes because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include the selling commissions paid

to JPMS and other affiliated or unaffiliated dealers, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. A portion of the profits, if any, realized in hedging our obligations under the notes may be allowed to other affiliated or unaffiliated dealers, and we or one or more of our affiliates will retain any remaining hedging profits. See “Selected Risk Considerations — The Estimated Value of the Notes Will Be Lower Than the Original Issue Price (Price to Public) of the Notes” in this pricing supplement.

Secondary Market Prices of the Notes

For information about factors that will impact any secondary market prices of the notes, see “Risk Factors — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement. In addition, we generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. These costs can include projected hedging profits, if any, and, in some circumstances, estimated hedging costs and our internal secondary market funding rates for structured debt issuances. This initial predetermined time period is intended to be the shorter of six months and one-half of the stated term of the notes. The length of any such initial period reflects the structure of the notes, whether our affiliates expect to earn a profit in connection with our hedging activities, the estimated costs of hedging the notes and when these costs are incurred, as determined by our affiliates. See “Selected Risk Considerations — The Value of the Notes as Published by JPMS (and Which May Be Reflected on Customer Account Statements) May Be Higher Than the Then-Current Estimated Value of the Notes for a Limited Time Period” in this pricing supplement.

Supplemental Use of Proceeds

The notes are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the notes. See “How the Notes Work” and “Hypothetical Payout Examples” in this pricing supplement for an illustration of the risk-return profile of the notes and “The Reference Stock” in this pricing supplement for a description of the market exposure provided by the notes.

The original issue price of the notes is equal to the estimated value of the notes plus the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes, plus the estimated cost of hedging our obligations under the notes.

Supplemental Plan of Distribution

We expect that delivery of the notes will be made against payment for the notes on or about the Original Issue Date set forth on the front cover of this pricing supplement, which will be the third business day following the Pricing Date of the notes (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, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on any date prior to two business days before delivery will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

Additional Terms Specific to the Notes

You may revoke your offer to purchase the notes at any time prior to the time at which we accept such offer by notifying the applicable agent. We reserve the right to change the terms of, or reject any offer to purchase, the notes prior to their issuance. In the event of any changes to the terms of the notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes, in which case we may reject your offer to purchase.
