JPMorgan Alerian MLP Index ETNs OVERVIEW JPMorgan Alerian MLP Index Exchange Traded Notes ("ETNs") provide access to midstream energy MLPs. The ETNs pay a variable quarterly coupon linked to the cash distributions paid on the MLPs in the index, less accrued tracking fees(1). Investors can trade the ETNs on the NYSE Arca exchange or receive a cash payment at the scheduled maturity or upon early repurchase(2), based on the performance of the index. The ETNs are unsecured and unsubordinated obligations of JPMorgan Chase and Co. For information about recent events please see "Recent Developments" on page PS-1 of the reopening supplement to this offering. MAXIMUM ISSUANCE LIMITATION The ETNs are subject to a maximum issuance limitation of 129,000,000 number of ETNs, which may cause the ETNs to trade at a premium in relation to their IIV (defined below). Investors that pay a premium for the ETNs could incur significant losses if that investor sells its ETNs at a time when some or all of the premium is no longer present. JPMorgan Chase & Co. issued the remaining 11,050,000 ETNs authorized for issuance on June 19, 2012. Sources: Bloomberg, JPMorgan. Calculated as of August 27, 2012.

The "Accrued Tracking Fee" for a given coupon period, as more fully described in the relevant pricing supplement, represents an amount equal to the Tracking Fee of 0.85% per annum accrued for that coupon period multiplied by the Current Indicative Value on the Index Business Day prior to the date of determination, plus the aggregate amounts, if any, by which the previous Accrued Tracking Fees have exceeded the cash distributions, if any, made by the underlying MLPs. 2. Investors may request on a weekly basis that the Issuer repurchase a minimum of 50,000 notes prior to the maturity date, subject to the procedures described in the relevant pricing supplement. Early repurchases will be subject to a Repurchase Fee of 0.125% , as further described in the relevant pricing supplement. 3. The intraday indicative value of the ETNs (the "IIV") is meant to approximate the intrinsic economic value of an ETN. The IIV calculation will be provided for reference purposes only. It is not intended as a price or quotation. The IIV will be based on the intraday indicative values of the Index, and may not be equal to the payment at maturity or upon early repurchase. It is possible that the maximum issuance limitation of 129,000,000 number of ETNs may cause the ETNs to trade at a significant premium in relation to the IIV. ETN investors should always consult their advisors before purchasing or selling the ETNs, particularly if the ETNs are trading at a premium over the IIV. Please see the relevant reopening pricing supplement for details. 4. Current yield equals the most recent coupon, with ex-dividend data on or before August 24, 2012, annualized and divided by the closing price of the ETN on August 27, 2012 and rounded to two decimal places for ease of presentation. The coupons are based on the cash distributions, if any, paid on the underlying MLPs, less the Accrued Tracking Fee. The coupons are variable and may be zero. 5. This number, in some cases, has been rounded for ease of presentation. As of August 27, 2012, the Market Capitalization of the ETNs was $5,045,190,000 which equals the closing price of the ETNs on August 27, 2012 multiplied by the number of ETNs issued as of August 27, 2012, including any ETNs held by an affiliate of JPMorgan Chase and Co. 6. As of August 27, 2012, the current maximum market capitalization of the ETNs was $5,045,190,000 which equals the maximum number of ETNs authorized for issuance of 129,000,000 multiplied by the closing price of the ETNs on August 27, 2012.

Contact Details Telephone: 800-576-3529 Website: www.jpmorganetns.com Email: alerian_etn@jpmorgan.com MLP Overview: What are MLPs? Master Limited Partnerships ("MLPs") are limited partnerships that are publicly traded on a U.S. securities exchange. The majority of MLPs currently operate in the energy infrastructure industry, owning assets such as pipelines that transport crude oil, natural gas and other refined petroleum products. MLPs typically generate fee-based revenues, which tend not to be directly tied to changes in commodity prices. Why invest in MLPs? MLPs provide relatively low correlation to a wide range of asset classes including equities and commodities and have produced attractive historical yields compared to other income-oriented investments. Benefits of Investing in the ETNs Exposure to a portfolio of energy MLPs through a single investment. Income via quarterly coupons linked to the cash distributions, if any, paid on the MLPs in the Index, less fees. No K-1 forms will be received by investors in the ETNs. The coupons are reported as ordinary income on Form 1099. There is no leverage to the MLPs in the ETN performance . What are the main risks in the ETNs? The ETNs may result in a loss. The ETNs are exposed to the credit risk of JPMorgan Chase & Co. The ETNs may not have an active trading market and may not continue to be listed over their term. The ETNs are subject to a maximum issuance limitation of 129,000,000 number of ETNs, which may cause the ETNs to trade at a premium to its IIV. Investors that pay a premium for the ETNs may incur a substantial loss if they sell the ETNs when some or all of the premium is no longer present. The payment at maturity or upon early repurchase of the ETNs will be based on the VWAP Level of the Index and not on the closing level of the Index. The VWAP Level of the Index will most likely differ from the closing level of the Index or the IIV. The coupon payments on the ETNs will be variable and may be zero. The Accrued Tracking Fee reduces the potential coupons and/or the payment at maturity or upon early repurchase. The Issuer's obligation to repurchase the ETNs is on a weekly basis, and is subject to substantial minimum size restrictions. You will not know how much you will receive upon early repurchase at the time that you elect we repurchase your ETNs. The risks identified above are not exhaustive.
