General Information
Listing:	The SPARQS have been approved for listing on the AMEX subject to official notice of issuance.  The AMEX listing symbol for the SPARQS is “AHY.”  It is not possible to predict whether any secondary market for the SPARQS will develop.
CUSIP:	617475561
Minimum ticketing size:	25SPARQS
Tax considerations:	The U.S. federal income tax consequences of an investment in the SPARQS are uncertain.  There is no direct legal authority as to the proper tax treatment of the SPARQS, and the Issuer’s counsel has not rendered an opinion as to their proper characterization for U.S. federal income tax purposes.  Pursuant to the terms of the SPARQS and subject to the discussion in the accompanying prospectus supplement for SPARQS under “United States Federal Taxation,” you agree with the Issuer to treat a SPARQS as a unit consisting of (i) a terminable forward contract and (ii) a deposit with the Issuer of a fixed amount of cash to secure your obligation under the terminable forward contract.  We have determined that the Yield on the Deposit is 5.38% per annum compounded quarterly, and that the remainder of the stated interest payments on the SPARQS is attributable to the Contract Fees, as described in the section of the accompanying prospectus supplement called “United States Federal Taxation — Tax Treatment of the SPARQS.” Assuming the characterization of the SPARQS as set forth above is respected, the following U.S. federal income tax consequences would result.  The portion of the stated interest payment on the SPARQS that is attributable to the deposit will be taxable to a U.S. Holder as ordinary interest income.  The Issuer will treat the portion of the stated interest payment that is attributable to the terminable forward contract as ordinary income.  Based on the tax treatment described above, upon sale, exchange or redemption of the SPARQS solely for cash, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized and the issue price.  Upon physical settlement of the terminable forward contract at maturity, a U.S. Holder generally will not recognize any gain or loss with respect to the underlying equity received and will have a tax basis in the underlying equity received equal to the issue price. Please read the discussion under “Risk Factors ― Structure Specific Risk Factors” in this pricing supplement and the discussion under “United States Federal Taxation” in the accompanying prospectus supplement for SPARQS concerning the U.S. federal income tax consequences of investing in the SPARQS. Notwithstanding the foregoing, any stated interest payments on the SPARQS made to non-U.S. holders (as defined in the accompanying prospectus supplement for SPARQS) will generally be withheld upon at a rate of 30%.   See the section called “United States Federal Taxation — Tax Consequences to Non-U.S. Holders” in the accompanying prospectus supplement for SPARQS.  Non-U.S. holders should also note that the discussion in the accompanying prospectus supplement for SPARQS does not address the tax consequences to non-U.S. holders for whom income or gain in respect of the SPARQS is effectively connected with the conduct of a trade or business in the United States.
Trustee:	The Bank of New York (as successor trustee to JPMorgan Chase Bank, N.A.)
Calculation agent:	Morgan Stanley & Co. Incorporated (“MS & Co.”)
Use of proceeds and hedging:	The net proceeds we receive from the sale of the SPARQS will be used for general corporate purposes and, in part, in connection with hedging our obligations under the SPARQS through one or more of our subsidiaries. On, or prior to, the pricing date, we, through our subsidiaries or others, hedged our anticipated exposure in connection with the SPARQS by taking positions in AAPL Stock and in options contracts on AAPL Stock listed on major securities markets.  Such purchase activity could have increased the price of AAPL Stock, and, accordingly, could have increased the issue price of the SPARQS, and therefore, the price at which AAPL Stock must close before you would receive for each SPARQS at maturity an amount of common stock worth as much as or more than the stated principal amount of the SPARQS.  For further information on our use of proceeds and hedging, see “Use of Proceeds and Hedging” in the prospectus supplement for SPARQS.
ERISA:	See “ERISA” in the prospectus supplement for SPARQS.
Contact:	You may contact your local Morgan Stanley branch office or our principal executive offices at 1585 Broadway, New York, New York, 10036 (telephone number (866) 477-4776 / (914) 225-7000).

Hypothetical Call Price Calculations

The following tables set forth sample values based on calculations of the call price for hypothetical call dates as indicated based on the following terms:

Original issue date:	June 29, 2007
Interest payment dates:	October 20, 2007, January 20, 2008, April 20, 2008 and the maturity date.
Yield to call:	19% per annum (computed on the basis of a 360-day year of twelve 30-day months)
Stated principal amount:	$24.60 per SPARQS
Interest rate:	10% per annum
Discount factor:	1 / 1.19x, where x is the number of years from the original issue date to, and including, the applicable call date.
The call price with respect to any call date is an amount of cash per SPARQS such that the sum of the present values of all cash flows on each SPARQS to, and including, the call date (i.e., the call price and all of the interest payments and accrued interest on each SPARQS), discounted to the original issue date at the applicable discount factor, equals the stated principal amount.  The discount factor is based on the yield to call rate of 19% per annum and the number of years (or fraction of a year) from the original issue date to, and including, the applicable call date. Each of the call price and total amount received calculations below are based upon the terms set forth above and the sample call dates as indicated.  The actual amount you will receive if the issuer calls the SPARQS will depend upon the actual terms of the SPARQS and the actual call date.
Call on January 20, 2008 (first call date)
Call price received:	$25.7020
Total amount received over the term of the SPARQS:	$27.0755
Call on February 29, 2008 (random interim call date)
Call price received:	$25.9313
Total amount received over the term of the SPARQS:	$27.5645
Call on July 20, 2008 (maturity date)
Call price received:	$26.7802
Total amount received over the term of the SPARQS:	$29.3837

The table on the following page sets forth a more detailed sample calculation of the call price for a hypothetical call date of January 20, 2008 based upon the terms set forth above.

Hypothetical Call Price Calculations (continued)

The call price in the hypothetical example shown below is determined as follows:

¡   The known cash flows on the SPARQS (i.e., the interest payments) are discounted to their present value on the original issue date at the applicable discount factor.  The sum of these present values equals the present value on the original issue date of all of the interest payments payable on the SPARQS to, and including, the applicable call date.

–     For example, the present value of all of the interest payments for the hypothetical call date of January 20, 2008 is $1.2770 ($0.7189 + $0.5581).

¡   Since the present value of all payments on the SPARQS to, and including, the call date (i.e., the call price and all of the interest payment on each SPARQS) must equal the stated principal amount, the issuer can determine the present value of the applicable call price by subtracting the sum of the present values of the interest payments from the stated principal amount.

–     For example, for the hypothetical call date of January 20, 2008, the present value of the call price is $23.3230 ($24.60 - $1.2770).

¡   The call price is then derived by determining the amount that, when discounted to the original issue date from the applicable call date at the applicable discount factor, equals the present value of the call price.

–     For the hypothetical call date of January 20, 2008, the call price is therefore $25.7020, which is the amount that, if paid on January 20, 2008, has a present value on the original issue date of $23.3230, based on the applicable discount factor.

The call price calculated in the following table is based upon the terms set forth above and the sample call date of January 20, 2008. The actual amount you will receive, if the issuer calls the SPARQS, will depend upon the actual terms of the SPARQS and the actual call date.

Call date (January 20, 2008)				$25.7020	$25.7020	201	0.55833	90.744%	$23.3230

Total amount received on the call date:  $26.3170

Total amount received over the term of the SPARQS $27.0755

1   The call price of $25.7020 is the dollar amount that has a present value of $23.3230, which has been discounted to the original issue date from the call date at the yield to call rate of 19% so that the sum of the present values of all of the interest payments on the SPARQS and the present value of the call price is equal to the stated principal amount of $24.60per SPARQS.

Risk Factors

The SPARQS are financial instruments that are suitable only for investors who are capable of understanding the complexities and risks specific to the SPARQS.  Accordingly, investors should consult their own investment, legal, tax, accounting and other advisors as to the risks entailed by an investment in the SPARQS and the suitability of such SPARQS in light of an investor’s particular circumstances.

The following is a non-exhaustive list of certain key considerations for investors in the SPARQS.  For a complete list of considerations and risk factors, you should read the section entitled “Risk Factors” beginning on page S-7 of the prospectus supplement for SPARQS.

Structure Specific Risk Factors

¡   No guaranteed return of principal.  If, at maturity, the closing price of AAPL Stock has declined from the closing price on the pricing date, and the issuer has not called the SPARQS, the payout at maturity will be less than the stated principal amount of the SPARQS.

¡   The return on the SPARQS is limited by the issuer’s call right.  The return you realize on the SPARQS is limited by the issuer’s call right.  The issuer may call the SPARQS at any time beginning January 20, 2008, including at maturity, for the cash call price, which will be calculated based on the call date.  The call price will be an amount of cash per SPARQS that, together with all of the interest paid on the SPARQS to and including the call date, gives you a yield to call of 19% per annum on the stated principal amount of each SPARQS from, and including, the date of issuance to, but excluding, the call date.  You should not expect to obtain a total yield (including interest payments) of more than 19% per annum on the stated principal amount of the SPARQS to the call date.

¡   Market price influenced by many unpredictable factors.  Several factors will influence the value of the SPARQS in the secondary market.  It is expected that generally the trading price of AAPL Stock on any day will affect the value of the SPARQS more than any other single factor.  However, because of the issuer’s call right, the SPARQS may trade differently from AAPL Stock.  Other factors that may influence the value of the SPARQS include: the volatility of AAPL Stock, geopolitical conditions and economic, financial, political, regulatory or judicial events, interest and yield rates, time remaining until the issuer can call the SPARQS and until the SPARQS mature, the dividend rate on AAPL Stock, the issuer’s creditworthiness and the occurrence of certain events affecting Apple Inc. that may or may not require an adjustment to the exchange ratio.

¡   Maturity date of the SPARQS may be accelerated. The maturity of the SPARQS will be accelerated if (i) the closing price of AAPL Stock on any two consecutive trading days is less than (x) $2.00 times (y) the exchange ratio on the original issue date or (ii) there is an event of default with respect to the SPARQS.  The amount payable to you, if the maturity of the SPARQS is accelerated, will differ depending on the reason for the acceleration and may be substantially less than the principal amount of the SPARQS.

¡   No shareholder rights.  Investing in SPARQS is not equivalent to investing in AAPL Stock.  As an investor in the SPARQS, you will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to AAPL Stock.

¡   The SPARQS may become exchangeable into the common stock of companies other than Apple Inc.  Following certain corporate events relating to AAPL Stock, you will receive, at maturity, either the common stock of three companies in the same industry group as Apple Inc. in lieu of, or in addition to, AAPL Stock or the common stock of a successor corporation to Apple Inc.  For these

June 2007 Page 6

10% SPARQS

Mandatorily Exchangeable for

Common Stock of Apple Inc.

SPARQS, the three companies would be selected from the S&P 500^® Index.  The occurrence of such corporate events and the consequent adjustments may materially and adversely affect the market price of the SPARQS.

¡   Antidilution adjustments.  Although the calculation agent will adjust the amount payable at maturity for certain corporate events affecting AAPL Stock, other corporate events may occur (such as partial tender or exchange offers) for which the calculation agent is not required to make any adjustments.  If an event occurs that does not require the calculation agent to adjust the amount of AAPL Stock payable at maturity, the market price of the SPARQS may be materially and adversely affected.

¡   The inclusion of commissions and projected profit from hedging in the original issue price is likely to adversely affect secondary market prices.  Assuming no change in market conditions or any other relevant factors, the price, if any, at which MS & Co. is willing to purchase SPARQS in secondary market transactions will likely be lower than the original issue price, since the original issue price included, and secondary market prices are likely to exclude, commissions paid with respect to the SPARQS, as well as the projected profit included in the cost of hedging the issuer’s obligations under the SPARQS.

¡   The U.S. federal income tax consequences of an investment in the SPARQS are uncertain.  There is no direct legal authority as to the proper tax treatment of the SPARQS, and the Issuer’s counsel has not rendered an opinion as to their proper characterization for U.S. federal income tax purposes.   Please read the discussion under “Fact Sheet ― General Information ― Tax Considerations” in this pricing supplement and the discussion under “United States Federal Taxation” in the accompanying prospectus supplement for SPARQS (together the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of investing in the SPARQS.  If the Internal Revenue Service (the “IRS”) were successful in asserting an alternative characterization for the SPARQS, the timing and character of income on the SPARQS might differ from the tax treatment described in the Tax Disclosure Sections.  The Issuer does not plan to request a ruling from the IRS regarding the tax treatment of the SPARQS, and the IRS or a court may not agree with the tax treatment described in this pricing supplement and the prospectus supplement for SPARQS.

Other Risk Factors

¡   Secondary trading may be limited.  There may be little or no secondary market for the SPARQS.  Because it is not possible to predict whether the market for the SPARQS will be liquid or illiquid, you should be willing to hold your SPARQS to maturity.

¡   No affiliation with Apple Inc.  Apple Inc. is not an affiliate of ours, is not involved with this offering in any way, and has no obligation to consider your interests in taking any corporate actions that might affect the value of the SPARQS.  The issuer has not made any due diligence inquiry with respect to Apple Inc. in connection with this offering.

¡   Potential adverse economic interest of the calculation agent.  The economic interest of the calculation agent and other affiliates of ours that will carry out hedging activities related to the SPARQS, or that trade AAPL Stock on a regular basis, are potentially adverse to your interests as an investor in the SPARQS.  The hedging or trading activities of the issuer’s affiliates on or prior to the pricing date and during the term of the SPARQS could have adversely affected the price of AAPL Stock on the pricing date and could adversely affect the price of AAPL Stock at maturity and, as a result, could decrease the value of the payment you receive on the SPARQS at maturity.  Any of

June 2007 Page 7

10% SPARQS

Mandatorily Exchangeable for

Common Stock of Apple Inc.

¡   these hedging or trading activities on or prior to the pricing date could have potentially affected the price of AAPL Stock and, accordingly, could have increased the issue price of the SPARQS and, therefore, the price at which AAPL Stock must close before you would receive at maturity an amount of AAPL Stock worth as much as or more than the issue price of the SPARQS.  Additionally, such hedging or trading activities during the term of the SPARQS could adversely affect the price of AAPL Stock at maturity and, accordingly, if the issuer has not called the SPARQS, the value of AAPL Stock, or in certain circumstances cash, you will receive at maturity, including upon an acceleration event.

¡   Morgan Stanley may engage in business with or involving Apple Inc. without regard to your interests.  The issuer or its affiliates may presently or from time to time engage in business with Apple Inc. without regard to your interests, and thus may acquire non-public information about Apple Inc.  Neither the issuer nor any of its affiliates undertakes to disclose any such information to you.  In addition, the issuer or its affiliates from time to time have published and in the future may publish research reports with respect to Apple Inc., which may or may not recommend that investors buy or hold AAPL Stock.
