Postponement of maturity date:

In 2007, the U.S. Treasury Department and the Internal Revenue Service (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 holders of 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; whether short-term instruments should be subject to any such accrual regime; the relevance of factors such as the exchange-traded status of the instruments and the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose an interest charge. 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 and adversely affect the tax consequences of an investment in the Trigger PLUS, possibly with retroactive effect.

Both U.S. and non-U.S. investors considering an investment in the Trigger PLUS should read the discussion under “Risk Factors” in this document and the discussion under “United States Federal Taxation” in the accompanying prospectus supplement for PLUS and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the Trigger PLUS, including possible alternative treatments, the issues presented by the aforementioned notice and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The discussion in the preceding paragraphs under “Tax considerations” and the discussion contained in the section entitled “United States Federal Taxation” in the accompanying prospectus supplement for PLUS, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell

The following section replaces the section entitled “Description of PLUS—Alternate Exchange Calculation in Case of an Event of Default” in the accompanying prospectus supplement for PLUS:

In case an event of default with respect to the Trigger PLUS shall have occurred and be continuing, the amount declared due and payable per Trigger PLUS upon any acceleration of the Trigger PLUS shall be an amount in cash equal to the value of such Trigger PLUS on the day that is two business days prior to the date of such acceleration, as determined by the calculation agent (acting in good faith and in a commercially reasonable manner) by reference to factors that the calculation agent considers relevant, including, without limitation: (i) then-current market interest rates; (ii) our credit spreads as of the pricing date, without adjusting for any subsequent changes to our creditworthiness; and (iii) the then-current value of the performance-based component of such Trigger PLUS. Because the calculation agent will take into account movements in market interest rates, any increase in market interest rates since the pricing date will lower the value of your claim in comparison to if such movements were not taken into account.

Notwithstanding the foregoing, if a voluntary or involuntary liquidation, bankruptcy or insolvency of, or any analogous proceeding is filed with respect to the issuer, then depending on applicable bankruptcy law, your claim may be limited to an amount that could be less than the default amount.

The proceeds from the sale of the Trigger PLUS will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per Trigger PLUS issued, because, when we enter into hedging transactions in order to meet our obligations under the Trigger PLUS, our hedging counterparty will reimburse the cost of the agent’s commissions. The costs of the Trigger PLUS borne by you and described on page 2 above comprise the agent’s commissions and the cost of issuing, structuring and hedging the Trigger PLUS.

On or prior to the pricing date, we will hedge our anticipated exposure in connection with the Trigger PLUS by entering into hedging transactions with our affiliates and/or third party dealers. We expect our hedging counterparties to take positions in the underlying commodity or futures contracts or forward contracts on the underlying commodity or positions in any other available instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the price of the underlying commodity on the pricing date, and therefore, could increase the trigger level, which is the price at or above which the underlying commodity must close on the valuation date so that investors do not suffer a significant loss on their initial investment in the Trigger PLUS. In addition, through our affiliates, we are likely to modify our hedge position throughout the life of the Trigger PLUS, including on the valuation date, by purchasing and selling the underlying commodity or futures contracts or forward contracts on the underlying commodity or positions in any other available securities or instruments that we may wish to use in connection with such hedging activities. As a result, these entities may be unwinding or adjusting hedge positions during the term of the Trigger PLUS, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches. We cannot give any assurance that our hedging activities will not affect the price of the underlying commodity and, therefore, adversely affect the value of the Trigger PLUS or the payment you will receive at maturity, if any. For further information on our use of proceeds and hedging, see “Use of Proceeds and Hedging” in the accompanying prospectus supplement for PLUS.

Each fiduciary of a pension, profit-sharing or other employee benefit plan subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) (a “Plan”), should consider the fiduciary standards of ERISA in the context of the Plan’s particular circumstances before authorizing an investment in the Trigger PLUS. Accordingly, among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the Plan.

In addition, we and certain of our affiliates, including MS & Co., may each be considered a “party in interest” within the meaning of ERISA, or a “disqualified person” within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”), with respect to many Plans, as well as many individual retirement accounts and Keogh plans (such accounts and plans, together with other plans, accounts and arrangements subject to Section 4975 of the Code, also “Plans”). ERISA Section 406 and Section 4975 of the Code generally prohibit transactions between Plans and parties in interest or disqualified persons. Prohibited transactions within the meaning of ERISA or the Code would likely arise, for example, if the Trigger PLUS are acquired by or with the assets of a Plan with respect to which MS & Co. or any of its affiliates is a service provider or other party in interest, unless the Trigger PLUS are acquired pursuant to an exemption from the “prohibited transaction” rules. A violation of these “prohibited transaction” rules could result in an excise tax or other liabilities under ERISA and/or Section 4975 of the Code for those persons, unless exemptive relief is available under an applicable statutory or administrative exemption.

The U.S. Department of Labor has issued five prohibited transaction class exemptions (“PTCEs”) that may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase or holding of the Trigger PLUS. Those class exemptions are PTCE 96-23 (for certain transactions determined by in-

house asset managers), PTCE 95-60 (for certain transactions involving insurance company general accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 90-1 (for certain transactions involving insurance company separate accounts) and PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide an exemption for the purchase and sale of securities and the related lending transactions, provided that neither the issuer of the securities nor any of its affiliates has or exercises any discretionary authority or control or renders any investment advice with respect to the assets of the Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than “adequate consideration” in connection with the transaction (the so-called “service provider” exemption). There can be no assurance that any of these class or statutory exemptions will be available with respect to transactions involving the Trigger PLUS.

Because we may be considered a party in interest with respect to many Plans, the Trigger PLUS may not be purchased, held or disposed of by any Plan, any entity whose underlying assets include “plan assets” by reason of any Plan’s investment in the entity (a “Plan Asset Entity”) or any person investing “plan assets” of any Plan, unless such purchase, holding or disposition is eligible for exemptive relief, including relief available under PTCEs 96-23, 95-60, 91-38, 90-1, 84-14 or the service provider exemption or such purchase, holding or disposition is otherwise not prohibited. Any purchaser, including any fiduciary purchasing on behalf of a Plan, transferee or holder of the Trigger PLUS will be deemed to have represented, in its corporate and its fiduciary capacity, by its purchase and holding of the Trigger PLUS that either (a) it is not a Plan or a Plan Asset Entity and is not purchasing such Trigger PLUS on behalf of or with “plan assets” of any Plan or with any assets of a governmental, non-U.S. or church plan that is subject to any federal, state, local or non-U.S. law that is substantially similar to the provisions of Section 406 of ERISA or Section 4975 of the Code (“Similar Law”) or (b) its purchase, holding and disposition of these Trigger PLUS will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or violate any Similar Law.

Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering purchasing the Trigger PLUS on behalf of or with “plan assets” of any Plan consult with their counsel regarding the availability of exemptive relief.

The Trigger PLUS are contractual financial instruments. The financial exposure provided by the Trigger PLUS is not a substitute or proxy for, and is not intended as a substitute or proxy for, individualized investment management or advice for the benefit of any purchaser or holder of the Trigger PLUS. The Trigger PLUS have not been designed and will not be administered in a manner intended to reflect the individualized needs and objectives of any purchaser or holder of the Trigger PLUS.

Each purchaser or holder of any Trigger PLUS acknowledges and agrees that:

(i)   the purchaser or holder or its fiduciary has made and shall make all investment decisions for the purchaser or holder and the purchaser or holder has not relied and shall not rely in any way upon us or our affiliates to act as a fiduciary or adviser of the purchaser or holder with respect to (A) the design and terms of the Trigger PLUS, (B) the purchaser or holder’s investment in the Trigger PLUS, or (C) the exercise of or failure to exercise any rights we have under or with respect to the Trigger PLUS;

(ii)  we and our affiliates have acted and will act solely for our own account in connection with (A) all transactions relating to the Trigger PLUS and (B) all hedging transactions in connection with our obligations under the Trigger PLUS;

(iii) any and all assets and positions relating to hedging transactions by us or our affiliates are assets and positions of those entities and are not assets and positions held for the benefit of the purchaser or holder;

(iv)  our interests are adverse to the interests of the purchaser or holder; and

(v)   neither we nor any of our affiliates is a fiduciary or adviser of the purchaser or holder in connection with any such assets, positions or transactions, and any information that we or any of our affiliates may provide is not intended to be impartial investment advice.

Each purchaser and holder of the Trigger PLUS has exclusive responsibility for ensuring that its purchase, holding and disposition of the Trigger PLUS do not violate the prohibited transaction rules of ERISA or the Code or any Similar Law. The sale of any Trigger PLUS to any Plan or plan subject to Similar Law is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all

relevant legal requirements with respect to investments by plans generally or any particular plan, or that such an investment is appropriate for plans generally or any particular plan. In this regard, neither this discussion nor anything provided in this document is or is intended to be investment advice directed at any potential Plan purchaser or at Plan purchasers generally and such purchasers of these Trigger PLUS should consult and rely on their own counsel and advisers as to whether an investment in these Trigger PLUS is suitable.

However, individual retirement accounts, individual retirement annuities and Keogh plans, as well as employee benefit plans that permit participants to direct the investment of their accounts, will not be permitted to purchase or hold the Trigger PLUS if the account, plan or annuity is for the benefit of an employee of Morgan Stanley or Morgan Stanley Wealth Management or a family member and the employee receives any compensation (such as, for example, an addition to bonus) based on the purchase of the Trigger PLUS by the account, plan or annuity.

The agent may distribute the Trigger PLUS through Morgan Stanley Smith Barney LLC (“Morgan Stanley Wealth Management”), as selected dealer, or other dealers, which may include Morgan Stanley & Co. International plc (“MSIP”) and Bank Morgan Stanley AG. Morgan Stanley Wealth Management, MSIP and Bank Morgan Stanley AG are affiliates of ours. Selected dealers, including Morgan Stanley Wealth Management, and their financial advisors will collectively receive from the agent, Morgan Stanley & Co. LLC, a fixed sales commission of $17.50 for each Trigger PLUS they sell. In addition, Morgan Stanley Wealth Management will receive a structuring fee of $5 for each Trigger PLUS.

MS & Co. is an affiliate of MSFL and a wholly owned subsidiary of Morgan Stanley and it and other affiliates of ours expect to make a profit by selling, structuring and, when applicable, hedging the Trigger PLUS. When MS & Co. prices this offering of Trigger PLUS, it will determine the economic terms of the Trigger PLUS such that for each Trigger PLUS the estimated value on the pricing date will be no lower than the minimum level described in “Investment Summary” on page 3.
