Additional Information about JPMorgan Chase & Co. and the Securities

You should read this pricing supplement together with the prospectus, as supplemented by the prospectus supplement, each dated November 7, 2014, relating to our Series E medium-term notes of which these Securities are a part, and the more detailed information contained in product supplement no. UBS-1a-I dated November 7, 2014 and underlying supplement no. 1a-I. This pricing supplement, together with the documents listed below, contains the terms of the Securities, supplements the free writing prospectus related hereto and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, correspondence, trade ideas, structures for implementation, sample structures, fact sheets, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in "Risk Factors" in the accompanying product supplement no. UBS-1a-I and "Risk Factors" in the accompanying underlying supplement no. 1a-I, as the Securities involve risks not associated with conventional debt securities.

You may access these on the SEC website at www.sec.gov as follows (or if such address has changed, by reviewing our filing for the relevant date on the SEC website):

As used in this pricing supplement, the "Issuer," "JPMorgan Chase," "we," "us" and "our" refer to JPMorgan Chase & Co.

Investor Suitability

The suitability considerations identified above are not exhaustive. Whether or not the Securities are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisers have carefully considered the suitability of an investment in the Securities in light of your particular circumstances. You should also review carefully the "Key Risks" beginning on page 6 of this pricing supplement and "Risk Factors" in the accompanying product supplement no. UBS-1a-I for risks related to an investment in the Securities.

What Are the Tax Consequences of the Securities?

You should review carefully the section entitled "Material U.S. Federal Income Tax Consequences" in the accompanying product supplement no. UBS-1a-I. In determining our reporting responsibilities we intend to treat (i) the Securities for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any Contingent Coupons 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 no. UBS-1a-I. 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.

Sale, Exchange or Redemption of a Security. Assuming the treatment described above is respected, upon a sale or exchange of the Securities (including redemption upon an automatic call or at maturity), you should recognize capital gain or loss equal to the difference between the amount realized on the sale or exchange and your tax basis in the Securities, which should equal the amount you paid to acquire the Securities (assuming Contingent Coupons are properly treated as ordinary income, consistent with the position referred to above). This gain or loss should be short-term capital gain or loss unless you hold the Securities for more than one year, in which case the gain or loss should be long-term capital gain or loss, whether or not you are an initial purchaser of the Securities at the issue price. The deductibility of capital losses is subject to limitations. If you sell your Securities between the time your right to a Contingent Coupon is fixed and the time it is paid, it is likely that you will be treated as receiving ordinary income equal to the Contingent Coupon. Although uncertain, it is possible that proceeds received from the sale or exchange of your Securities prior to an Observation Date but that can be attributed to an expected Contingent Coupon payment could be treated as ordinary income. You should consult your tax adviser regarding this issue.

As described above, 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 Securities 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 Securities, possibly with retroactive effect. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Securities 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 Coupons is uncertain, and although we believe it is reasonable to take a position that Contingent Coupons 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 Securities 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 Securities in light of your particular circumstances.

FATCA. Withholding under legislation commonly referred to as "FATCA" could apply to payments on the Securities, and (if they are recharacterized, in whole or in part, as debt instruments) could also apply to the payment of gross proceeds of a sale of a Security occurring after December 31, 2016 (including an automatic call or redemption at maturity). You should consult your tax adviser regarding the potential application of FATCA to the Securities.

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

Key Risks

An investment in the Securities involves significant risks. Investing in the Securities is not equivalent to investing directly in the Index. These risks are explained in more detail in the "Risk Factors" section of the accompanying product supplement no. UBS-1a-I and the "Risk Factors" section of the accompanying underlying supplement no. 1a-I. We also urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Securities.

Risks Relating to the Securities Generally

Risks Relating to the Index

Hypothetical Examples

The examples below illustrate the hypothetical payments on a Coupon Payment Date, upon an automatic call or at maturity under different hypothetical scenarios for a $10.00 Security on an offering of the Securities linked to a hypothetical Index and assume an Initial Index Level of 100 and reflect the Contingent Coupon Rate of 5.50% per annum and a Trigger Level and Coupon Barrier of 70.00 (which is 70.00% of the hypothetical Initial Level). The hypothetical Initial Index Level has been chosen for illustrative purposes only and does not represent the actual Initial Index Level. The actual Initial Index Level, Trigger Level and Coupon Barrier are based on the closing level of the Index on the March 16, 2015 and are specified on the cover of this pricing supplement.* For historical data regarding the actual closing levels of the Index, please see the historical information set forth under "The Index" in this pricing supplement.

The examples below are purely hypothetical and are not based on any specific offering of Securities linked to any specific Index. These examples are intended to illustrate how the value of any payment on the Securities will depend on the closing level on the Observation Dates.

Example 1 — Securities Are Automatically Called on the Fourth Observation Date

Although the closing level is above the Initial Index Level on the first Observation Date, the Securities are not called because the Securities cannot be called before the fourth Observation Date. Because the Securities are automatically called on the fourth Observation Date, we will pay you on the applicable Call Settlement Date a total of $10.1375 per Security, reflecting your principal amount plus the applicable Contingent Coupon. When that amount is added to the Contingent Coupon payment of $0.1375 received in respect of prior Observation Dates, we will have paid you a total of $10.275 per Security for a 2.75% total return on the Securities. No further amounts will be owed on the Securities.

Example 2 — Securities Are Automatically Called on the Fifth Observation Date

Because the Securities are automatically called on the fifth Observation Date, we will pay you on the applicable Call Settlement Date a total of $10.1375 per Security, reflecting your principal amount plus the applicable Contingent Coupon. When that amount is added to the Contingent Coupon payments of $0.55 received in respect of prior Observation Dates, we will have paid you a total of $10.6875 per Security for a 6.875% total return on the Securities. No further amounts will be owed on the Securities.

Example 3 — Securities Are NOT Automatically Called and the Final Index Level Is at or above the Trigger Level and the Coupon Barrier

At maturity, we will pay you a total of $10.1375 per Security, reflecting your principal amount plus the applicable Contingent Coupon. When that amount is added to the Contingent Coupon payment of $0.1375 received in respect of prior Observation Dates, we will have paid you a total of $10.275 per Security for a 2.75% total return on the Securities.

Example 4 — Securities Are NOT Automatically Called and the Final Index Level Is below the Trigger Level and the Coupon Barrier

Because the Securities are not automatically called, the Final Index Level is below the Trigger Level and the Coupon Barrier and the Index Return is -45%, at maturity we will pay you $5.50 per Security. When that amount is added to the Contingent Coupon payments of $1.5125 received in respect of prior Observation Dates, we will have paid you $7.0125 per Security for a loss on the Securities of 29.875%.

Example 5 — Securities Are NOT Automatically Called and the Final Index Level is below the Trigger Level and the Coupon Barrier

Because the Securities are not automatically called, the Final Index Level is below the Trigger Level and the Coupon Barrier and the Index Return is -50%, at maturity we will pay you $5.00 per Security for a loss on the Securities of 50.00%. Because there is no Contingent Coupon paid during the term of the Securities, that represents the total payment on the Securities.

The hypothetical returns and hypothetical payments on the Securities shown above apply only if you hold the Securities for their entire term or until called. These hypotheticals do not reflect 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.

Supplemental Plan of Distribution

We have agreed to indemnify UBS and JPMS against liabilities under the Securities Act of 1933, as amended, or to contribute to payments that UBS may be required to make relating to these liabilities as described in the prospectus supplement and the prospectus. We have agreed that UBS may sell all or a part of the Securities that it purchases from us to the public or its affiliates at the price to public indicated on the cover hereof.

Subject to regulatory constraints, JPMS intends to offer to purchase the Securities in the secondary market, but it is not required to do so.

We or our affiliates may enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the Securities, and JPMS and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions. See "Supplemental Use of Proceeds" in this pricing supplement and "Use of Proceeds and Hedging" beginning on page PS-43 of the accompanying product supplement no. UBS-1a-I.

We expect that delivery of the Securities will be made against payment for the Securities on or about the Settlement Date set forth on the front cover of this pricing supplement, which will be the fourth business day following the Trade Date of the Securities (this settlement cycle being referred to as T+4). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade Securities on the Trade Date 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.

JPMS's Estimated Value of the Securities

JPMS's estimated value of the Securities 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 Securities, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the Securities. JPMS's estimated value does not represent a minimum price at which JPMS would be willing to buy your Securities in any secondary market (if any exists) at any time. The internal funding rate used in the determination of JPMS's estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. For additional information, see "Key Risks — Risks Relating to the Securities Generally — JPMS's Estimated Value Is Not Determined by Reference to Credit Spreads for Our Conventional Fixed-Rate Debt." The value of the derivative or derivatives underlying the economic terms of the Securities is derived from JPMS's internal pricing models. 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, JPMS's estimated value of the Securities is determined when the terms of the Securities are set based on market conditions and other relevant factors and assumptions existing at that time. See "Key Risks — Risks Relating to the Securities Generally — JPMS's Estimated Value Does Not Represent Future Values of the Securities and May Differ from Others' Estimates."

JPMS's estimated value of the Securities is lower than the original issue price of the Securities because costs associated with selling, structuring and hedging the Securities are included in the original issue price of the Securities. These costs include the selling commissions paid to UBS, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the Securities and the estimated cost of hedging our obligations under the Securities. 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. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the Securities. See "Key Risks — Risks Relating to the Securities Generally — JPMS's Estimated Value of the Securities Is Lower Than the Original Issue Price (Price to Public) of the Securities" in this pricing supplement.

Secondary Market Prices of the Securities

For information about factors that will impact any secondary market prices of the Securities, see "Key Risks — Risks Relating to the Securities Generally — Secondary Market Prices of the Securities Will Be Impacted by Many Economic and Market Factors" in this pricing supplement. In addition, we generally expect that some of the costs included in the original issue price of the Securities will be partially paid back to you in connection with any repurchases of your Securities by JPMS in an amount that will decline to zero over an initial predetermined period that is intended to be approximately five months. The length of any such initial period reflects secondary market volumes for the Securities, the structure of the Securities, whether our affiliates expect to earn a profit in connection with our hedging activities, the estimated costs of hedging the Securities and when these costs are incurred, as determined by JPMS. See "Key Risks — Risks Relating to the Securities Generally — The Value of the Securities as Published by JPMS (and Which May Be Reflected on Customer Account Statements) May Be Higher Than JPMS's Then-Current Estimated Value of the Securities for a Limited Time Period."

Supplemental Use of Proceeds

The Securities are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the Securities. See "Hypothetical Examples" in this pricing supplement for an illustration of the risk-return profile of the Securities and "The Index" in this pricing supplement for a description of the market exposure provided by the Securities.

The original issue price of the Securities is equal to JPMS's estimated value of the Securities plus the selling commissions paid to UBS, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the Securities, plus the estimated cost of hedging our obligations under the Securities.

Validity of the Securities

In the opinion of Davis Polk & Wardwell LLP, as our special products counsel, when the Securities offered by this pricing supplement have been executed and issued by us and authenticated by the trustee pursuant to the indenture, and delivered against payment as contemplated herein, such Securities will be our valid and binding obligations, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors' rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above. This opinion is given as of the date hereof and is limited to the federal laws of the United States of America, the laws of the State of New York and the General Corporation Law of the State of Delaware. In addition, this opinion is subject to customary assumptions about the trustee's authorization, execution and delivery of the indenture and its authentication of the Securities and the validity, binding nature and enforceability of the indenture with respect to the trustee, all as stated in the letter of such counsel dated November 7, 2014, which was filed as an exhibit to the Registration Statement on Form S-3 by us on November 7, 2014.
