Overview Investor Material Important Information FAQs Morgan Stanley Cushing[R] MLP High Income Index ETN The Exchange Traded Notes (ETNs) are based on the performance of the Cushing[R] MLP High Income Index (the Index), which is a criteria-weighted index tracking the performance of 30 Master Limited Partnerships (MLPs) which hold energy and shipping assets in North America. These Index constituents are chosen for having the highest current indicative yields among MLPs meeting certain criteria(1). The quarterly coupon payments are linked to the cash distributions paid on the MLPs in the Index, less accrued tracking fees. The ETNs are senior, unsecured debt obligations of Morgan Stanley.

The quarterly distributions on the ETNs, if any, will be based on the actual quarterly distributions made by the MLPs that are included in the Index net of the Annual Tracking Fee of 0.85% per annum. (1) The "current indicative yield" of a security is defined as the last quarterly distribution annualized divided by the current security price, with adjustment in some cases made for more current information. See "Information About the Index--Current Indicative Yield" in the pricing supplement. Since the current indicative yield reflects only the last quarterly distribution by the MLP, there can be no assurance that the MLPs included in the Index based on this past performance will make any distributions in the next or any future period. (2) The "current indicative yield of ETN" equals the latest quarterly coupon annualized and divided by the ETN closing price on March 28, 2013.

MLP Overview What are MLPs? MLPs are partnerships that trade on U.S. public exchanges or markets (e.g., NYSE). Most MLPs own and operate assets in the energy sector as natural resource-based companies that own, build and maintain the energy infrastructure (e.g., pipelines, storage facilities, gathering systems and processing plants) of North America. They are structured as partnerships rather than taxable corporations, so they do not pay federal or state income taxes at the entity level. The business model of a typical MLP seeks the advantages of high barriers to entry, low price sensitivities and continued demand for energy-related products and services due to overall energy demand. Why invest in MLPs? MLPs have historically performed well in a variety of market environments, typically with low correlation to the market. Investors have favored this asset class for its recent history of high, stable and growing distributions. However, there can be no assurance that performance, low correlation or high distributions will continue in the future.

"Alerian MLP Index", "REITs Index", "Utilities Index", and "S[AND]P 500[R] Index" refer to the Alerian MLP Index, the Dow Jones U.S. Real Estate Index, the Utilities Select Sector Index, and the S[AND]P 500[R] Index, respectively. The last twelve month dividend yield equals the sum of gross dividend per share amounts that have gone ex-dividend over the prior 12 months, divided by the current price on the date shown above. Benefits of Investing in the ETNs [] Portfolio of MLPs: Exposure to a portfolio of 30 high income MLPs in a single investment. [] Variable quarterly coupons: Based on the cash distributions, if any, made by the MLPs in the Index, less fees. [] Simplified tax reporting: Investors receive Form 1099 (for coupon payments); no K-1 forms to deal with for underlying MLP exposure. [] Reduced tracking error: Performance calculated based on benchmark index. What are some of the key risks of an investment in the ETNs? [] The ETNs may result in a loss of some or all of your investment. [] The ETNs are unsecured debt obligations of Morgan Stanley and therefore are subject to the credit risk of Morgan Stanley. [] Coupon payments are not guaranteed, will be variable and may be zero. The Accrued Tracking Fee reduces the potential coupons and/or the payment at maturity, call or upon early repurchase. [] The ETNs may not have an active secondary market and may not continue to be listed over their term. [] The Index constituents are concentrated in the energy industry. The Index is solely comprised of securities of MLPs which hold energy and shipping assets in North America. [] The payment on the ETNs at maturity or call, or upon early repurchase, is linked to the VWAP Level, not to the closing level of the Index and not to the published intraday indicative value of the ETNs. The VWAP Level of the Underlying Index will most likely differ from the closing level of the Underlying Index. [] Your right to obligate us to repurchase the ETNs is on a weekly basis and is subject to a substantial minimum size restriction of at least 100,000 ETNs and a Repurchase Fee of 0.125% of the applicable Repurchase Amount as of the Repurchase Valuation Date. Liquidity could be limited if you hold less than the minimum amount of ETNs. [] The ETNs may be accelerated and mandatorily repurchased by the Issuer, resulting in a loss of some or all of your investment. [] You will not know the Repurchase Amount that you will receive at the time you elect to request that we repurchase your ETNs. [] Significant aspects of the tax treatment of the ETNs are uncertain. Morgan Stanley ETNs are debt securities subject to credit risk and not equivalent to exchange traded funds or ETFs that are typically registered investment companies that hold an underlying portfolio of securities. The risks identified above are not exhaustive.
