SUMMARY

The following summary describes the leveraged index-linked securities, offered under this program, in general terms only. You should read the summary together with the more detailed information contained in this prospectus supplement, in the accompanying prospectus and in the applicable pricing supplement. We may also prepare free writing prospectuses that describe particular issuances of leveraged index-linked securities. Any free writing prospectus should also be read in connection with this prospectus supplement and the accompanying prospectus. For purposes of this prospectus supplement, any references to an applicable pricing supplement may also refer to a free writing prospectus, unless the context otherwise requires.

We will sell these leveraged index-linked securities primarily in the United States, but may also sell them outside the United States or both in and outside the United States simultaneously. The leveraged index-linked securities we offer under this prospectus supplement are among the notes we refer to as our Series F medium-term notes. We refer to the offering of the Series F medium-term notes as our Series F program. See “Plan of Distribution” in this prospectus supplement.

General terms of the leveraged index-linked securities |  | Unlike ordinary debt securities, the leveraged index-linked securities do not guarantee any return of principal at maturity. The leveraged index-linked securities generally do not pay interest, but may do so if so specified in the applicable pricing supplement. At maturity, the leveraged index-linked securities will pay an amount in cash based upon the change in value of an index or a basket of indices, which we refer to as the underlying index or the underlying basket of indices. Some of the potential underlying indices that may be specified in the applicable pricing supplement are described in Annex A to this prospectus supplement titled “Underlying Indices and Underlying Index Publishers.”
Payment at maturity |  | At maturity, you will receive for each leveraged index-linked security that you hold an amount in cash based upon the value of the underlying index or basket of indices on the specified observation date, determined as follows: For leveraged index-linked securities without a buffer:

| • | If the ending index level is greater than the initial index level, you will receive for each leveraged index-linked security that you hold a payment at maturity equal to:
|  | provided that the payment at maturity in excess of the stated principal amount will be subject to any maximum total return specified in the applicable pricing supplement,
|  | where,

| stated principal |  | = |  | $1,000, unless otherwise specified in the applicable pricing |
| amount |  |  |  | supplement; |
| upside leverage |  | = |  | the factor specified in the applicable pricing supplement; and |
| factor |  |  |  |  |
| index return |  | = |  | ending index level – initial index level |
|  |  |  |  | initial index level |

S-4

| • | If the ending index level is less than or equal to the initial index level, you will receive for each leveraged index-linked security that you hold a payment at maturity that is less than the stated principal amount of each leveraged index-linked security by an amount proportionate to the decrease in value of the underlying index, which will be equal to:
| Because the index return will be less than or equal to 0, the payment at maturity will be less than or equal to the stated principal amount. Under no circumstances will the payment at maturity be less than zero.
| For leveraged index-linked securi ties with a buffer:
| • | If the ending index level is greater than the initial index level, you will receive for each leveraged index-linked security that you hold a payment at maturity equal to:
|  | provided that the payment a t maturity in excess of the stated principal amount will be subject to any maximum total return specified in the applicable pricing supplement,
| where,

| stated principal |  | = |  | $1,000, unless otherwise specified in the applicable pricing |
| amount |  |  |  | supplement; |
| upside leverage |  | = |  | the factor specified in the applicable pricing supplement; and |
| factor |  |  |  |  |
| index return |  | = |  | ending index level – initial index level |
|  |  |  |  | initial index level |

| • | If the ending index level is l ess than or equal to the initial index level, but has declined by an amount less than or equal to the buffer amount, you will receive for each leveraged index-linked security that you hold a payment at maturity equal to the stated principal amount.
| • | If the ending index level is l ess than the initial index level, and has declined by an amount greater than the buffe r amount, you will receive for each leveraged index- linked security that you hold a payment at maturity that is less than the stated principal amount of each lev eraged index-linked security by an amount proportionate to the decrease in value of the underlying index below the buffer amount times the downside factor, which will be equal to:

S-5

|  | where, |  |  |  |
|  | buffer amount |  | = |  | the percentage decline from the initial index level to which the ending index level may decline before you will lose any part of your stated principal amount; and
|  | downside factor |  | = |  | the factor specified in the applicable pricing supplement by which any percentage decline in the underlying index below the buffer amount is multiplied.
|  | Because in this scenario the sum of the index return and the buffer amount will be less than 0, the payment at maturity will be less than the stated principal amount. Under no circumstances will the payment at maturity be less than zero. Index return calculations: For purposes of determining the index return and the payment at maturity, we use the following terms:
|  | initial index level |  | = |  | the index closing level of the underlying index on the index setting date specified in the applicable pricing supplement;
|  | ending index level |  | = |  | the index closing level on the observation date;
|  | index closing level |  | = |  | the closing level of the underlying index or any successor index (as defined under “Description of Leveraged Index- Linked Securities—Discontinuance of Any Underlying Index; Alteration of Method of Calculation” below) published at the regular weekday close of trading on the relevant index business day. In certain circumstances, the index closing level will be based on the alternate calculation of the index described under “Description of Leveraged Index-Linked Securities—Discontinuance of Any Underlying Index; Alteration of Method of Calculation;” and
|  | observation date |  | = |  | the date specified in the applicable pricing supplement; provided that if a market disruption event occurs on the scheduled observation date or the scheduled observation date is not otherwise an index business day, the observation date will be subject to postponement for up to ten index business days. See “Description of Leveraged Index- Linked Securities—Payment at Maturity” in this prospectus supplement for leveraged index-linked securities.

|  | Certain issuances of leveraged index-linked securities will not be subject to a maximum total return and in such cases the payment at maturity will not be capped. In each applicable pricing supplement, we will provide a graph or table, which will illustrate the performance of the particular issuance of leveraged index-linked securities at maturity over a range of hypothetical percentage changes in the underlying index. You should also review the graphs in the section of this prospectus supplement titled

S-6

|  | “Hypothetical Payments on the Leveraged Index-Linked Securities at Maturity,” which provide illustrations of the payments for leveraged index-linked securities over a range of hypothetical changes in the value of the underlying index.
Other features of leveraged index-linked securities |  | Certain leveraged index-linked securities may have features that differ from the basic leveraged index-linked securities described above. An issuance of leveraged index- linked securities could combine more than one of the features listed below. Leveraged Index-Linked Securities Linked to a Basket of Indices: For issuances of leveraged index-linked securities that are linked to a basket of indices, at maturity you will receive for each leveraged index-linked security that you hold an amount in cash based upon the value of the underlying basket of indices on the specified observation date, determined as follows: For leveraged index-linked securities linked to a basket of indices without a buffer:

| • | If the ending basket level is greater than the starting basket level, you will receive for each leveraged index-linked security that you hold a payment at maturity equal to:
|  | provided that the payment at maturity in excess of the stated principal amount will b e subject to any maximum t otal return specified in the applicable pricing supplement,

| where, |  |  |  |
| stated principal |  | = |  | $1,00 0, unless otherwise specified in the applicable pricing
| amount |  |  |  | supple ment;
| basket return |  | = |  | the sum of the products, as calculated for each underlying
|  |  |  |  | index in the basket, of the index return for such basket index
|  |  |  |  | and its respective index weighting, as further described
|  |  |  |  | under “—Basket return calculations” below; and
| upside leverage |  | = |  | the factor specified in the applicable pricing supplement.
| factor |  |  |  |

| • | If the ending basket level is less than or equal to the starting basket level, you will receive for each leveraged index-linked security that you hold a payment at maturity that is less than the stated p rincipal amount of each leveraged index-linked security by an amount proportionate to the decrease in value of the basket, which will be equal to:

S-7

|  | Because the basket return will be less than or equal to 0, the payment at maturity will be less than or equal to the stated principal amount. Under no circumstances will the payment at maturity be less than zero.

|  | For leveraged index-linked securities linked to a basket of indices with a buffer:
| • | If the ending basket level is greater than the starting basket level, you will receive for each leveraged index-linked security that you hold a payment at maturity equal to:
|  | provided that the payment at maturity in excess of the stated principal amount will be subject to any maximum total return specified in the applicable pricing supplement,
| where, |

| stated principal |  | = |  | $1,00 0, unless otherwise specified in the applicable pricing
| amount |  |  |  | supple ment;
| basket return |  | = |  | the sum of the products, as calculated for each underlying
|  |  |  |  | index in the basket, of the index return for such basket index
|  |  |  |  | and its respective index weighting, as further described
|  |  |  |  | under “—Basket return calculations” below; and
| upside leverage |  | = |  | the factor specified in the applicable pricing supplement.
| factor |  |  |  |

| • | If the ending basket level is less than or equal to the starting basket level, but has declined by an amount less than or equal to the buffer amount, you will receive for each leveraged index-linked security that you hold a payment at maturity equal to the stated principal amount.
| • | If the ending basket level is less than the starting basket level, and has declined by an amount greater than the buffer amount, you will receive for each leveraged index-linked security that y ou hold a payment at maturity that is less than the stated principal amount of each lev eraged index-linked security by an amount proportionate to the decrease in value of the basket below the buffer amount times the downside factor, which will be equal to:
| where, |

S-8

| buffer amount |  | = |  | the percentage decline from the starting basket level to which the ending basket level may decline before you will lose any part of your stated principal amount; and
| downside factor |  | = |  | the factor specified in the applicable pricing supplement by which any percentage decline in the underlying basket of indices below the buffer amount is multiplied.

|  | Because in this scenario the sum of the basket return and the buffer amount will be less than 0, the payment at maturity will be less than the stated principal amount. Under no circumstances will the payment at maturity be less than zero.

| Basket return calculations:
| For purposes of determining the basket return and the payment at maturity, we use the following terms:
| starting basket level |  | = |  | a predetermined basket value specified in the applicable
|  |  |  |  | pricing supplement. The initial index weighting and the
|  |  |  |  | initial index level for each basket index included in the
|  |  |  |  | basket will be specified in the applicable pricing
|  |  |  |  | supplement. The initial index level for each basket index
|  |  |  |  | will be the closing level of such basket index on the
|  |  |  |  | applicable index setting date. The index weighting for each
|  |  |  |  | basket index will remain constant for the term of the
|  |  |  |  | leveraged index-linked securities.
| ending basket level |  | = |  | the basket closing level on the observation date
| basket closing level |  | = |  |

| basket return |  | = |  | the sum of the products, as calculated for each underlying
|  |  |  |  | index in the basket, of the index return for such basket
|  |  |  |  | index and its respective index weighting.
| index return |  | = |  | ending index level initial index level
|  |  |  |  | initial index level

|  | where, the ending index level is the index closing level of such basket index on the observation date. For example, in the case of an issuance of leveraged index-linked securities linked to the value of a basket composed of three indices, the basket return will be the sum of:

S-9

| observation date |  | = |  | the date specified in the applicable pricing supplement; provided that if a market disruption event occurs on the scheduled observation date or the scheduled observation date is not otherwise an index business day, the observation date will be subject to postponement for up to ten index business days. See “Description of Leveraged Index-Linked Securities—Payment at Maturity” in this prospectus supplement for leveraged index-linked securities.

|  | Averaging Dates: If the applicable pricing supplement specifies that an issuance of leveraged index-linked securities will have averaging dates, the payment at maturity will depend on the value of the underlying index or basket of indices as determined on a number of specified dates, and the mechanics described above under “—Payment at maturity” will apply, except that, the ending index level will equal: for leveraged index-linked securities linked to a single index, the arithmetic average of the index closing levels of the underlying index on the relevant averaging dates, as calculated by the Calculation Agent on the final averaging date, provided that if there is a market disruption event on any scheduled averaging date or if any scheduled averaging date is not otherwise an index business day, such averaging date will be the immediately succeeding index business day on which no market disruption event occurs; provided further that the final averaging date will be subject to postponement for up to ten index business days, or for leveraged index-linked securities linked to a basket of indices, the arithmetic average of the basket closing levels of the basket of indices on the relevant averaging dates, as calculated by the Calculation Agent on the final averaging date; provided that if any scheduled averaging date is not an index business day with respect to a basket index or if there is a market disruption event on any scheduled averaging date with respect to a basket index, such averaging date (solely with respect to the affected basket index) will be the immediately succeeding index business day on which no market disruption event occurs with respect to the affected basket index; provided further that the final averaging date will be subject to postponement for up to ten index business days. See “Description of Leveraged Index-Linked Securities—Payment at Maturity— Postponement of Observation Date; Averaging Dates” in this prospectus supplement for leveraged index-linked securities for a detailed description of the postponement procedures.

S-10

|  | Strike Level: For issuances of leveraged index-linked securities that have a strike level, which will be specified in the applicable pricing supplement, the mechanics described above under “— Payment at maturity” will apply, except that, in lieu of the initial index level, we will use the strike level which will equal a pre-determined percentage of the initial index level, which percentage will be specified in the applicable pricing supplement, and may be lower or greater than 100% of the initial index level. In the case of issuances of leveraged index-linked securities with a strike level, the payment at maturity will be calculated using the strike level and not the initial index level in calculating any index return.
Underlying Indices |  | For a description of certain indices to which the leveraged index-linked securities may be linked, see “Underlying Indices and Underlying Index Publishers Information” under Annex A attached to this prospectus supplement for leveraged index-linked securities. Any other index or indices to which the leveraged index-linked securities may be linked will be described in the applicable pricing supplement.
Postponement of Maturity Date |  | If due to a market disruption event or otherwise, the scheduled observation date or final averaging date is postponed, as described under “Description of Leveraged Index-Linked Securities—Payment at Maturity—Postponement of Observation Date; Averaging Dates,” to a date later than the third scheduled trading day prior to the scheduled maturity date, the maturity date will be the third scheduled trading day following the observation date or final averaging date as postponed.
The payment you receive, if any, on any leveraged index-linked security above the stated principal amount will be limited by the maximum total return |  | Unless the applicable pricing supplement for a leveraged index-linked security does not specify a maximum total return, the payment you receive on the leveraged index-linked securities above the stated principal amount, if any, will be limited by the maximum total return. Although the upside leverage factor provides increased exposure to any increase in the value of the underlying index at maturity, the payment at maturity in excess of the stated principal amount, if any, will never exceed the maximum total return, which will be a fixed percentage of the stated principal amount. In the case of leveraged index-linked securities without a buffer, in the event of any decrease in the value of the underlying index, you will realize the entire decline. Further, in the case of leveraged index-linked securities with a buffer, in the event of any decrease below the buffer amount, you will realize the decline beyond the buffer amount, as leveraged by the downside factor. As a result, you may receive less, and possibly significantly less, than the stated principal amount per leveraged index-linked security.
Issue price of the leveraged index-linked securities includes commissions and projected profit |  | The issue price of the leveraged index-linked securities, which will be specified in the applicable pricing supplement, includes the agent’s commissions paid with respect to the leveraged index-linked securities and the cost of hedging our obligations under the leveraged index-linked securities. The cost of hedging includes the projected profit that our subsidiaries may realize in consideration for assuming the risks inherent in managing the hedging transactions. The fact that the issue price of the leveraged index-linked securities includes these commissions and hedging costs is expected to adversely affect the secondary market prices of the leveraged index-linked securities. See “Risk Factors—The inclusion of commissions and projected profit from hedging in the original issue price is likely to adversely affect secondary market prices” and “Use of Proceeds and Hedging.”

S-11

Other terms of the leveraged index-linked securities |  | • | The leveraged index-linked securities may bear interest, if any, at either a fixed rate or a floating rate, as specified in the applicable pricing supplement and may pay such interest, if any, on the dates specified in the applicable pricing supplement.
|  | • | The leveraged index-linked securities will be denominated in U.S. dollars unless we specify otherwise in the applicable pricing supplement.
|  | • | You will not have the right to present the leveraged index-linked securities to us for repayment prior to maturity unless we specify otherwise in the applicable pricing supplement.
|  | • | We may from time to time, without your consent, create and issue additional leveraged index-linked securities with the same terms as leveraged index-linked securities previously issued so that they may be combined with the earlier issuance.
|  | • | The leveraged index-linked securities will not be listed on any securities exchange, unless we specify otherwise in the applicable pricing supplement.

MS & Co. will be the Calculation Agent |  | We have appointed our affiliate, Morgan Stanley & Co. Incorporated or its successors, which we refer to as MS & Co., to act as Calculation Agent for us with respect to the leveraged index-linked securities. As Calculation Agent, MS & Co. will determine the initial index level, the index closing levels, the ending index level, the index return, the starting basket level, the ending basket level, the basket closing levels, the basket return, the payment to you at maturity and whether a market disruption event has occurred. All determinations made by the Calculation Agent will be at the sole discretion of the Calculation Agent and will, in the absence of manifest error, be conclusive for all purposes and binding on you, the Trustee and us.
Forms of securities |  | The leveraged index-linked securities will be issued in fully registered form and will be represented by a global security registered in the name of a nominee of The Depository Trust Company, as depositary, unless we indicate in the applicable pricing supplement that they will be represented by certificates issued in definitive form. We will not issue book-entry securities as certificated securities except under the circumstances described in “Forms of Securities—The Depositary” in the prospectus, under which heading you may also find information on The Depository Trust Company’s book-entry system.
Where you can find more information on the leveraged index- linked securities |  | Because this is a summary, it does not contain all of the information that may be important to you. You should read the “Description of Leveraged Index-Linked Securities” section in this prospectus supplement and the “Description of Debt Securities” section in the prospectus for a detailed description of the terms of the leveraged index-linked securities. You should also read about some of the risks involved in investing in the leveraged index-linked securities in the section of this prospectus supplement called “Risk Factors.” We urge you to consult with your investment, legal, accounting and other advisors with regard to any investment in the leveraged index-linked securities.

HYPOTHETICAL PAYMENTS ON THE LEVERAGED INDEX-LINKED SECURITIES AT MATURITY

Leveraged Index-Linked Securities without a Buffer:

Assuming an issuance of leveraged index-linked securities with the hypothetical terms given below, the following graph illustrates the payment at maturity on each leveraged index-linked security for a range of hypothetical percentage changes in the underlying index or indices. The graph does not illustrate every percentage change that may occur. The Leveraged Zone illustrates the leveraging effect of the upside leverage factor taking into account the maximum total return. The graph is based on the following hypothetical terms:

• | stated principal amount per leveraged index-linked security: |  | $1,000
• | initial index level: |  | 1,000
• | upside leverage factor: |  | 2
• | maximum total return: |  | $200 (20% of the stated principal amount)

Where the ending index level is greater than the initial index level, the payment at maturity on the leveraged index-linked securities reflected in the graph below is greater than the $1,000 principal amount per leveraged index-linked security, but in all cases the payment at maturity in excess of the stated principal amount is subject to the maximum total return.

Where the ending index level is less than or equal to the initial index level, the payment at maturity on the leveraged index-linked securities reflected in the graph below is less than the $1,000 principal amount per leveraged index-linked security.

In the hypothetical example above, you will realize the maximum total return at the ending index level of 110% of the hypothetical initial index level because of the upside leverage factor. For a hypothetical initial index level of 1,000, you would realize the maximum total return at the ending index level of 1,100. You will not share in increases in the ending index level above 120% of the hypothetical initial index level, or 1,200.

Assuming an issuance of leveraged index-linked securities with the hypothetical terms given below, the following graph illustrates the payment at maturity on each leveraged index-linked security for a range of hypothetical percentage changes in the underlying index or indices. The graph does not illustrate every percentage change that may occur. The Leveraged Zone illustrates the leveraging effect of the upside leverage factor taking into account the maximum total return. The Buffer Zone illustrates the effect of the partial downside protection offered by the buffer amount. The graph is based on the following hypothetical terms:

• | stated principal amount per leveraged index-linked security: |  | $1,000
• | initial index level: |  | 1,000
• | upside leverage factor: |  | 2
• | downside factor: |  | 1.111
• | buffer amount: |  | 15%
• | maximum total return: |  | $200 (20% of the stated principal amount)

Where the ending index level is greater than the initial index level, the payment at maturity on the leveraged index-linked securities reflected in the graph below is greater than the $1,000 principal amount per leveraged index-linked security, but in all cases is subject to the maximum total return.

Where the ending index level is less than or equal to the initial index level, but has declined by an amount less than or equal to the buffer amount, the payment at maturity on the leveraged index-linked securities reflected in the graph below is $1,000.

Where the ending index level is less than the initial index level, and has declined by an amount greater than the buffer amount, the payment at maturity on the leveraged index-linked securities reflected in the graph below is less than the $1,000 principal amount per leveraged index-linked security.

In the hypothetical example above, you will realize the maximum total return at the ending index level of 110% of the hypothetical initial index level because of the upside leverage factor. For a hypothetical initial index level of 1,000, you would realize the maximum total return at the ending index level of 1,100. You will not share in increases in the ending index level above 120% of the hypothetical initial index level, or 1,200.

Leveraged Index-Linked Securities Linked to a Basket of Indices without a Buffer:

Assuming an issuance of leveraged index-linked securities with the hypothetical terms given below, the following tables illustrate the payment at maturity on each leveraged index-linked security for a range of hypothetical percentage changes in the basket. The tables are based on the following hypothetical terms:

• | stated principal amount per leveraged index-linked security: |  | $1,000
• | starting basket level: |  | 100
• | upside leverage factor: |  | 2
• | maximum total return: |  | $200 (20% of the stated principal amount)

Example 1: The index returns for all of the basket indices are positive.

|  | Percentage Weight |  | Hypothetical |  | Hypothetical |  | Index Return x
Basket Index |  | of Basket Index |  | Initial Index level |  | Ending Index Level |  | Index Weighting
Index A |  | 33.333% |  | 20 |  | 22 |  | 3.3333%
Index B |  | 33.333% |  | 80 |  | 88 |  | 3.3333%
Index C |  | 33.333% |  | 150 |  | 165 |  | 3.3333%
|  |  |  |  |  |  |  | 10%

The ending index level of each basket index in the above example is 10% higher than its initial index level and, accordingly, the basket return is 10%. The payment at maturity is calculated as follows:

> > > > > or

> provided that the payment at maturity in excess of the stated principal amount will be subject to any maximum total return specified in the applicable pricing supplement.

Therefore, in this hypothetical example, the total payment at maturity per leveraged index-linked security will equal $1,200, which is the sum of the stated principal amount and the product of (a) the stated principal amount, (b) the basket return and (c) the upside leverage factor. In this scenario, the payment you will receive at maturity in excess of the stated principal amount is equal to the maximum total return. This is the maximum payment that is payable on the leveraged index-linked securities.

Example 2: Two of the basket indices have a positive index return, but this is offset by a negative index return of the third basket index with the greatest index weighting.

|  | Percentage Weight |  | Hypothetical |  | Hypothetical |  | Index Return x
Basket Index |  | of Basket Index |  | Initial Index level |  | Ending Index Level |  | Index Weighting
Index A |  | 25% |  | 20 |  | 24 |  | 5%
Index B |  | 50% |  | 80 |  | 40 |  | -25%
Index C |  | 25% |  | 150 |  | 165 |  | 2.5%
|  |  |  |  |  |  |  | -17.5%

S-15

The ending index level of Index A is 20% greater than its initial index level and the ending index level of Index C is 10% greater than its initial index level. However, the ending index level of Index B, which represents 50% of the basket, is 50% lower than its initial index level. Accordingly, the basket return is -17.5% . The payment at maturity is calculated as follows:

Therefore, in this hypothetical example, the total payment at maturity per leveraged index-linked security will equal $825, which is the sum of the stated principal amount and the product of (a) the stated principal amount and (b) the basket return. Because the basket return is less than 0, the payment at maturity is less than the stated principal amount.

Leveraged Index-Linked Securities Linked to a Basket of Indices with a Buffer:

Assuming an issuance of leveraged index-linked securities with the hypothetical terms given below, the following tables illustrate the payment at maturity on each leveraged index-linked security for a range of hypothetical percentage changes in the basket. The tables are based on the following hypothetical terms:

• | stated principal amount per leveraged index-linked security: |  | $1,000
• | starting basket level: |  | 100
• | upside leverage factor: |  | 2
• | buffer amount: |  | 15%
• | downside factor: |  | 1.111
• | maximum total return: |  | $200 (20% of the stated principal amount)

Example 1: The index returns for all of the basket indices are positive.

|  | Percentage Weight |  | Hypothetical |  | Hypothetical |  | Index Return x
Basket Index |  | of Basket Index |  | Initial Index level |  | Ending Index Level |  | Index Weighting
Index A |  | 33.333% |  | 20 |  | 22 |  | 3.3333%
Index B |  | 33.333% |  | 80 |  | 88 |  | 3.3333%
Index C |  | 33.333% |  | 150 |  | 165 |  | 3.3333%
|  |  |  |  |  |  |  | 10%

The ending index level of each basket index in the above example is 10% higher than its initial index level and, accordingly, the basket return is 10%. The payment at maturity is calculated as follows:

> provided that the payment at maturity in excess of the stated principal amount will be subject to any maximum total return specified in the applicable pricing supplement.

Therefore, in this hypothetical example, the total payment at maturity per leveraged index-linked security will equal $1,200, which is the sum of the stated principal amount and the product of (a) the stated principal amount, (b) the basket return and (c) the upside leverage factor.

Example 2: Two of the basket indices have a positive index return, but this is offset by a negative index return of the third basket index with the greatest index weighting.

|  | Percentage Weight |  | Hypothetical |  | Hypothetical |  | Index Return x
Basket Index |  | of Basket Index |  | Initial Index level |  | Ending Index Level |  | Index Weighting
Index A |  | 25% |  | 20 |  | 24 |  | 5%
Index B |  | 50% |  | 80 |  | 40 |  | -25%
Index C |  | 25% |  | 150 |  | 165 |  | 2.5%
|  |  |  |  |  |  |  | -17.5%

S-17

The ending index level of Index A is 20% greater than its initial index level and the ending index level of Index C is 10% greater than its initial index level. However, the ending index level of Index B, which represents 50% of the basket, is 50% lower than its initial index level. Accordingly, the basket return is -17.5%, and has declined by an amount greater than the buffer amount. The payment at maturity is calculated as follows:

Therefore, in this hypothetical example, the total payment at maturity per leveraged index-linked security will equal $972, which is the sum of the stated principal amount and the product of (a) the stated principal amount, (b) the basket return plus the buffer amount and (c) the downside factor. Because the basket return plus the buffer amount is less than 0, the payment at maturity is less than the stated principal amount.

Example 3: The basket return is negative but the extent of the decline in the basket closing level is less than the buffer amount.

|  | Percentage Weight |  | Hypothetical |  | Hypothetical |  | Index Return x
Basket Index |  | of Basket Index |  | Initial Index level |  | Ending Index Level |  | Index Weighting
Index A |  | 25% |  | 20 |  | 16 |  | -5%
Index B |  | 50% |  | 80 |  | 72 |  | -5%
Index C |  | 25% |  | 150 |  | 165 |  | 2.5%
|  |  |  |  |  |  |  | -7.5%

In this hypothetical example, even though the basket return is -7.5%, the basket closing level has not declined by an amount greater than the buffer amount of 15%. Therefore, you would receive at maturity the stated principal amount of $1,000 for each leveraged index-linked security you hold.

S-18

RISK FACTORS

The leveraged index-linked securities are not secured debt, are riskier than ordinary debt securities and, unlike ordinary debt securities, the leveraged index-linked securities generally do not pay interest or guarantee any return of principal at maturity. The return investors realize on the leveraged index-linked securities above the stated principal amount is generally limited by the maximum total return. This section describes the most significant risks relating to the leveraged index-linked securities. You should carefully consider whether the leveraged index-linked securities are suited to your particular circumstances before you decide to purchase them.

Leveraged index-linked securities generally do not pay interest or guarantee any return of principal

The terms of the leveraged index-linked securities differ from those of ordinary debt securities in that we do not guarantee to pay you the principal amount of the leveraged index-linked securities at maturity and generally do not pay you interest on the leveraged index-linked securities. Instead, at maturity, you will receive for each leveraged index-linked security that you hold an amount in cash based upon the ending index level (or ending basket level) as follows:

For leveraged index-linked securities without a buffer:

- If the ending index level (or ending basket level) is greater than the initial index level (or starting basket level), you will receive a return on the principal amount of the leveraged index-linked securities equal to the index return (or basket return) times the upside leverage factor, provided that the payment at maturity in excess of the stated principal amount will be subject to the maximum total return, if any.
- If the ending index level (or ending basket level) is less than the initial index level (or starting basket level), you will lose some or all of your investment.

For leveraged index-linked securities with a buffer:

- If the ending index level (or ending basket level) is greater than the initial index level (or starting basket level), you will receive a return on the principal amount of the leveraged index-linked securities equal to the index return (or basket return) times the upside leverage factor, provided that the payment at maturity in excess of the stated principal amount will be subject to the maximum total return, if any.
- If the ending index level (or ending basket level) is less than the initial index level (or starting basket level), but has not declined by an amount greater than the buffer amount, you will receive an amount in cash equal to the stated principal amount. Because the leveraged index-linked securities do not pay interest, even if you receive the principal amount at maturity, the return on the principal amount of the leveraged index-linked securities will be less than the amount that would be paid on an ordinary debt security.
- If the ending index level (or ending basket level) is less than the initial index level (or starting basket level), and has declined by an amount greater than the buffer amount, you will lose some or all of your investment.

Your appreciation potential is limited

The appreciation potential of the leveraged index-linked securities above the stated principal amount is generally limited by the maximum total return. Although the upside leverage factor provides increased exposure to any increase in the value of the underlying index or indices over the term of the leveraged index-linked securities, the payment at maturity in excess of the stated principal amount will never exceed the maximum total return, which will be a fixed percentage of the stated principal amount. In the case of leveraged index-linked securities without a buffer, in the event that the value of the underlying index or basket of indices decreases over the term of the leveraged index-linked securities, you will incur the entire decline. Further, in the case of leveraged index-linked securities with a buffer, in the event that the value of the underlying index or basket of indices decreases by more than the buffer amount over the term of the leveraged index-linked securities, you will incur the decline beyond the

S-19

buffer amount, multiplied by the downside factor. As a result, you may receive less, and possibly significantly less, than the stated principal amount per leveraged index-linked security.

Secondary trading may be limited

There may be little or no secondary market for the leveraged index-linked securities. Although we may apply to list certain issuances of leveraged index-linked securities, we may not meet the requirements for listing and do not expect to announce whether or not we will meet such requirements prior to the pricing of the leveraged index-linked securities. Even if there is a secondary market, it may not provide significant liquidity. MS & Co. currently intends to act as a market maker for the leveraged index-linked securities but is not required to do so. If, at any time, MS & Co. were to cease acting as a market maker, it is likely that there would be significantly less liquidity in the secondary market, in which case the price at which you would be able to sell your leveraged index-linked securities would likely be lower than if an active market existed. If the leveraged index-linked securities are not listed on any securities exchange and MS & Co. were to cease acting as a market maker, it is likely that there would be no secondary market for the leveraged index-linked securities.

Market price of the leveraged index-linked securities may be influenced by many unpredictable factors

Several factors, many of which are beyond our control, will influence the value of the leveraged index-linked securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the leveraged index-linked securities in the secondary market, including:

- the value of the underlying index or indices at any time, including on the observation date or on the specified averaging dates;
- the volatility (frequency and magnitude of changes in value) of the underlying index or indices;
- the interest and yield rates in the market;
- the dividend rate on the stocks constituting the underlying index or indices;
- geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the securities constituting the underlying index or indices or stock markets generally and which may affect the ending index level (or ending basket level);
- the time remaining until the leveraged index-linked securities mature; and
- our creditworthiness.

Some or all of these factors will influence the price you will receive if you sell your leveraged index-linked securities prior to maturity. For example, you may have to sell your leveraged index-linked securities at a substantial discount from the principal amount if, at the time of sale or on earlier averaging dates, the underlying index or basket of indices is at or below the initial index level or starting basket level.

You cannot predict the future performance of the underlying index or indices based on historical performance. The value of the applicable underlying index or indices may decrease so that you will receive at maturity a payment that is less than the principal amount of the leveraged index-linked securities by an amount proportionate to the decrease in the value of the underlying index or indices. In addition, there can be no assurance that the value of the underlying index or indices will increase so that you will receive at maturity an amount in excess of the principal amount of the leveraged index-linked securities. Nor can there be any assurance that the value of the underlying index or indices will not increase by more than the maximum total return, in which case you will only receive the stated principal amount plus the maximum total return.

S-20

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 leveraged index-linked securities in secondary market transactions will likely be lower than the original issue price, since the original issue price includes, and secondary market prices are likely to exclude, commissions paid with respect to the leveraged index-linked securities, as well as the projected profit included in the cost of hedging our obligations under the leveraged index-linked securities. In addition, any such prices may differ from values determined by pricing models used by MS & Co. as a result of dealer discounts, mark-ups or other transaction costs.

The basket indices may not be equally weighted

If the leveraged index-linked securities are linked to a basket of indices, the component indices may have different weights in determining the value of the basket. In such case, the same percentage change in two of the basket indices could have different effects on the basket closing value because of the unequal index weighting. For example, if the index weighting of one basket index is greater than the index weighting of another basket index, a 5% decrease in the value of the basket index with the greater index weighting will have a greater impact on the basket closing value than a 5% increase in the value of the basket index with the lesser index weighting.

Changes in the value of one or more of the basket indices may offset each other

For leveraged index-linked securities where the payment at maturity is based on a basket of two or more indices, price movements in the basket indices may not correlate with each other. At a time when the value of one or more of the basket indices increases, the value of one or more of the other basket indices may not increase as much or may even decline in value. Therefore, in calculating the basket closing level on an observation date or on an averaging date, increases in the value of one or more of the basket indices may be moderated, or wholly offset, by lesser increases or declines in the value of one or more of the other basket indices.

You can review the historical prices of each of the basket indices in the section called “Historical Information” in the applicable pricing supplement. You cannot predict the future performance of any of the basket indices or of the basket as a whole, or whether increases in the levels of any of the basket indices will be offset by decreases in the levels of other basket indices, based on their historical performance. In addition, there can be no assurance that the ending basket level will be higher than the starting basket level. If the ending basket level for a leveraged index-linked security without a buffer is below the starting basket level, you will lose money on your investment. If the ending basket level for a leveraged index-linked security with a buffer has decreased by more than the buffer amount, you will incur the decline below the buffer amount, multiplied by the downside factor.

In the case of leveraged index-linked securities with specified averaging dates, you may lose some of your investment even where the ending index level (or ending basket level) is higher than the initial index level (or starting basket level)

In the case of issuances of leveraged index-linked securities where the payment at maturity is determined based on the index closing level (or basket closing level) on specified averaging dates over the term of the leveraged index-linked securities, you will receive a payment at maturity that is greater than the stated principal amount of the leveraged index-linked securities only if the arithmetic average of the index return (or basket return) on the averaging dates is greater than zero. A positive index return (or basket return) on any one averaging date may be partially or entirely offset by a lesser or negative index return (or basket return) on any other averaging date. Consequently, it is possible that you may lose some of your investment even if the underlying index or basket of indices has increased substantially on the final averaging date.

S-21

In the case of issuances of leveraged index-linked securities with a strike level above 100%, the ending index level (or ending basket level) must increase above the strike level for you to receive more than the principal amount at maturity

For issuances of leveraged index-linked securities that have a strike level in lieu of the initial index level (or starting basket level), we will use the strike level, which will equal a pre-determined percentage of the initial index level (or starting basket level), to determine the payment at maturity. In the event that the strike level is greater than 100%, the ending index level (or ending basket level) will have to increase to a level greater than the strike level before you will receive a payment at maturity that exceeds the stated principal amount of the leveraged index-linked securities. You will not benefit from any appreciation in the value of the underlying index or indices below the strike level.

The leveraged index-linked securities are designed to be held to maturity

The leveraged index-linked securities are not designed to be short-term trading instruments. The price at which you will be able to sell your leveraged index-linked securities prior to maturity, if at all, may be at a substantial discount from the principal amount of the leveraged index-linked securities, even in cases where the index or basket of indices has appreciated since the date of the issuance of the leveraged index-linked securities. The potential returns described in any pricing supplement assume that your leveraged index-linked securities are held to maturity.

Investing in the leveraged index-linked securities is not equivalent to investing in the underlying index or indices, or their component stocks

Investing in the leveraged index-linked securities is not equivalent to investing in the underlying index or basket of indices or their component stocks. The payment you receive at maturity on the leveraged index-linked securities will be based on the index closing level (or basket closing level) of the underlying index or indices only on the specified observation date or averaging dates. In addition, the index closing level (or basket closing level) on any day reflects the prices of the component common stocks of the underlying index or indices but does not take into consideration the value of dividends paid on those stocks. As an investor in the leveraged index-linked securities, you will not have voting rights to receive dividends or other distributions or any other rights with respect to the stocks that underlie the underlying index or indices.

Adjustments to the underlying index or indices could adversely affect the value of the leveraged index-linked securities

The index publishers are responsible for calculating and maintaining the underlying index or indices. Index publishers can add, delete or substitute the stocks constituting the underlying index or basket index or make other methodological changes that could change the value of the underlying index or indices. Any of these actions could adversely affect the value of the leveraged index-linked securities.

The index publishers may discontinue or suspend calculation or publication of the underlying index or basket index at any time. In these circumstances, MS & Co., as the Calculation Agent, will have the sole discretion to substitute a successor index that is comparable to the discontinued underlying index or indices. MS & Co. could have an economic interest that is different than that of investors in the leveraged index-linked securities insofar as, for example, MS & Co. is not precluded from considering indices that are calculated and published by MS & Co. or any of its affiliates. If MS & Co. determines that there is no appropriate successor index, at maturity the payout on the leveraged index-linked securities will be an amount based on the closing prices at maturity of the stocks underlying the affected index at the time of such discontinuance, without rebalancing or substitution, computed by the Calculation Agent in accordance with the formula for calculating the affected index last in effect prior to discontinuance of the underlying index or basket index.

There are risks associated with investments in leveraged index-linked securities linked to the value of indices of foreign equity securities

Investments in leveraged index-linked securities linked to the value of indices comprising foreign equity securities involve risks associated with the foreign securities market, including volatility, governmental intervention and cross-shareholdings among companies in such foreign indices. Also, there is generally less publicly available

S-22

information about foreign companies than about U.S. companies that are subject to the reporting requirements of the United States Securities and Exchange Commission, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements different from those applicable to U.S. reporting companies.

The prices of securities in countries other than the United States that may underlie certain indices may be affected by political, economic, financial and social factors in such jurisdictions, including changes in a country’s government, economic and fiscal policies and currency exchange laws. Moreover, the economies in such countries may differ favorably or unfavorably from the economy in the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency. Such countries may be subjected to different and, in some cases, more adverse economic environments.

Leveraged index-linked securities linked to certain indices, like the MSCI EAFE Index or the Dow Jones EURO STOXX 50 Index are subject to currency exchange risk

Because the prices of the component securities are converted into U.S. dollars for purposes of calculating the value of certain indices, such as the MSCI EAFE Index (and its component country indices) or the Dow Jones EURO STOXX 50 Index, holders of the leveraged index-linked securities will be exposed to currency exchange rate risk with respect to each of the currencies represented in indices calculated in that manner. An investor’s net exposure will depend on the extent to which the currencies represented in such an index strengthen or weaken against the U.S. dollar and the relative weight of each relevant currency represented in the overall index. If, taking into account such index weighting, the dollar strengthens against the component currencies, the value of the relevant index will be adversely affected and the payment at maturity of the leveraged index-linked securities may be reduced.

Of particular importance to potential currency exchange risk are:

- existing and expected rates of inflation;
- existing and expected interest rate levels;
- the balance of payments; and
- the extent of governmental surpluses or deficits in the underlying countries and the United States of America.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of various component countries and the United States and other countries important to international trade and finance.

The economic interests of the Calculation Agent and other affiliates of ours are potentially adverse to your interests

The economic interests of the Calculation Agent and other affiliates of ours are potentially adverse to your interests as an investor in the leveraged index-linked securities.

As Calculation Agent, MS & Co. will determine the initial index level, the ending index level, the starting basket level, the ending basket level and calculate the amount of cash, if any, you will receive at maturity. Determinations made by MS & Co., in its capacity as Calculation Agent, including with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or calculation of any index closing level or basket closing level in the event of a discontinuance of the underlying index or indices, may affect the payout to you at maturity. See the sections of this prospectus supplement called “Description of Leveraged Index-Linked Securities—General Terms of the Leveraged Index-Linked Securities—Some Definitions” and “Discontinuance of Any Underlying Index; Alteration of Method of Calculation.”

The original issue price of the leveraged index-linked securities includes the agent’s commissions and certain costs of hedging our obligations under the leveraged index-linked securities. The subsidiaries through which we hedge our obligations under the leveraged index-linked securities expect to make a profit. Since hedging our obligations entails risk and may be influenced by market forces beyond our or our subsidiaries’ control, such hedging may result in a profit that is more or less than initially projected.

S-23

Hedging and trading activity by the Calculation Agent and its affiliates could potentially adversely affect the value of the leveraged index-linked securities

MS & Co. and other affiliates of ours will carry out, hedging activities related to the leveraged index-linked securities (and possibly to other instruments linked to the underlying index or indices or their component stocks), including trading in the stocks that constitute the underlying index or indices as well as in other instruments related to the underlying index or indices or their underlying stocks. MS & Co. and some of our other subsidiaries also trade the stocks that constitute the underlying index or indices and other financial instruments related to the underlying index or indices and the stocks that constitute the underlying index or indices on a regular basis as part of their general broker-dealer and other businesses. Any of these hedging or trading activities on or prior to the index setting date could potentially affect the initial index level or starting basket level and, therefore, could increase the value at which the underlying index or indices must close on the observation date or on the averaging dates before you receive a payment at maturity that exceeds the principal amount of the leveraged index-linked securities. Additionally, such hedging or trading activities during the term of the leveraged index-linked securities could adversely affect the value of the underlying index or indices on the observation date or on the averaging dates, and, accordingly, the amount of cash you will receive at maturity.

The tax consequences of an investment in the leveraged index-linked securities are unclear.

There is no direct legal authority as to the proper U.S. federal income tax characterization of the leveraged index-linked securities, and we do not intend to request a ruling from the Internal Revenue Service (the “IRS”) regarding the leveraged index-linked securities. No assurance can be given that the IRS will accept, or that a court will uphold, the characterization and tax treatment of the leveraged index-linked securities described in “United States Federal Taxation.” If the IRS were successful in asserting an alternative characterization for the leveraged index-linked securities, the timing and character of income on the leveraged index-linked securities could differ materially from our description herein. Non-U.S. Holders should note that, if all or any portion of a leveraged index-linked security were recharacterized as a debt instrument, tax may be withheld upon at a rate of 30% unless the Non-U.S. Holder has submitted a properly completed IRS Form W-8BEN or otherwise satisfy the applicable documentation requirements. You are urged to review carefully the section entitled “United States Federal Taxation” in this prospectus supplement and consult your tax advisors regarding your particular circumstances.

If you are a non-U.S. investor, please also read the section of this prospectus supplement called “United States Federal Taxation.”

You are urged to consult your own tax advisors regarding all aspects of the U.S. federal income tax consequences of investing in the leveraged index-linked securities as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

DESCRIPTION OF LEVERAGED INDEX-LINKED SECURITIES

Investors should carefully read the general terms and provisions of our debt securities in “Description of Debt Securities” in the prospectus. This section supplements that description. The pricing supplement will specify the particular terms for each issuance of leveraged index-linked securities, and may supplement, modify or replace any of the information in this section and in “Description of Debt Securities” in the prospectus. References in this prospectus supplement to a leveraged index-linked security shall refer to the stated principal amount specified as the denomination for that issuance of leveraged index-linked securities in the applicable pricing supplement.

The following terms used in this section are defined in the indicated sections of the accompanying prospectus:

- Senior Debt Indenture (“Description of Debt Securities—Indentures”)
- senior indebtedness (“Description of Debt Securities—Subordination Provisions”)

General Terms of Leveraged Index-Linked Securities

We will issue the leveraged index-linked securities as part of our Series F medium-term notes under the Senior Debt Indenture. The Series F medium-term notes issued under the Senior Debt Indenture, together with our senior Series G and Series H global medium-term notes, referred to below under “Plan of Distribution,” will constitute a single series under that indenture, together with any other obligations we issue in the future under the Senior Debt Indenture that we designate as being part of that series. The Senior Debt Indenture does not limit the amount of additional indebtedness that we may incur. We may, without your consent, create and issue additional leveraged index-linked securities with the same terms as previous issuances of leveraged index-linked securities, so that the additional leveraged index-linked securities will be considered as part of the same issuance as the earlier leveraged index-linked securities.

Ranking. Leveraged index-linked securities issued under the Senior Debt Indenture will rank on a parity with all of our other senior indebtedness and with all of our other unsecured and unsubordinated indebtedness, subject to statutory exceptions in the event of liquidation upon insolvency.

Terms Specified in Pricing Supplements. A pricing supplement will specify the following terms of any issuance of leveraged index-linked securities to the extent applicable:

- the issue price (price to public);
- the stated principal amount per leveraged index-linked security;
- the aggregate principal amount;
- the denominations or minimum denominations;
- the original issue date;
- the stated maturity date and any terms related to any extension of the maturity date not otherwise set forth in this prospectus supplement;
- the underlying index or basket of indices, and if so, the applicable index weighting for each basket index;
- the value of the underlying index or basket of indices on the index setting date;
- the upside leverage factor;
- the buffer amount;
- the downside factor;
- the maximum total return, if applicable;

S-25

- the rate per year at which the leveraged index-linked securities will bear interest, if any, or the method of calculating that rate and the dates on which interest will be payable;
- whether the leveraged index-linked securities may be redeemed, in whole or in part, at our option or repaid at your option, prior to the stated maturity date, and the terms of any redemption or repayment;
- if any leveraged index-linked security is not denominated and payable in U.S. dollars, the currency or currencies in which the principal, premium, if any, and interest, if any, will be paid, which we refer to as the “specified currency,” along with any other terms relating to the non-U.S. dollar denomination, including historical exchange rates as against the U.S. dollar;
- whether the leveraged index-linked securities will be listed on any stock exchange;
- whether the leveraged index-linked securities will be issued in book-entry or certificated form;
- if the leveraged index-linked securities are in book-entry form, whether the leveraged index-linked securities will be offered on a global basis to investors through Euroclear and Clearstream, Luxembourg as well as through the Depositary (each as defined below); and
- any other terms on which we will issue the leveraged index-linked securities.

Some Definitions. We have defined some of the terms that we use frequently in this prospectus supplement below:

“averaging dates” with respect to an issuance of leveraged index-linked securities will be specified in the applicable pricing supplement. The ending index level or ending basket level will be determined on the last averaging date, which we refer to as the “final averaging date.”

“basket closing level” on any date is the starting basket level plus the product of the (a) basket return and the (b) starting basket level. In certain circumstances, the basket closing level will be based on the alternate calculation of the basket indices described under “—Discontinuance of Any Underlying Index; Alteration of Method of Calculation.”

“basket index” with respect to an issuance of leveraged index-linked securities linked to a basket of indices, means each of the indices specified in the applicable pricing supplement, the performance of which underlies the leveraged index-linked securities.

“basket return” on any date is the sum of the products, as calculated for each underlying index in the basket, of the index return for such basket index and its respective index weighting. For example, in the case of an issuance of leveraged index-linked securities linked to the value of a basket composed of three indices, the basket return on any day, will be the sum of the following:

S-26

The index return for each basket index will be calculated using the following formula:

|  |  |  | ending index level - initial index level
index return |  | = |  |
|  |  |  | initial index level

where, the initial index level is the index closing level of such basket index on the applicable index setting date and the ending index level is the index closing level of such basket index on the relevant date.

“buffer amount” means the percentage decline from the initial index level or the starting basket level, as applicable, to which the ending index level or ending basket level may decline before you will lose any part of the principal amount of your notes.

“business day” means any day, other than a Saturday or Sunday, (i) that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close (a) in The City of New York or (b) for leveraged index-linked securities denominated in a specified currency other than U.S. dollars, euro or Australian dollars, in the principal financial center of the country of the specified currency or (c) for leveraged index-linked securities denominated in Australian dollars, in Sydney, and (ii) for leveraged index-linked securities denominated in euro, a day that is also a TARGET Settlement Day.

“Clearstream, Luxembourg” means Clearstream Banking, société anonyme.

“Depositary” means The Depository Trust Company (“DTC”), New York, New York.

“downside factor” means the factor specified in the applicable pricing supplement by which any percentage decline in the underlying index or basket of indices below the buffer amount is multiplied.

“ending basket level” with respect an issuance of leveraged index-linked securities linked to a basket of indices will be:

- for issuances of leveraged index-linked securities with an observation date: the ending basket level will be the basket closing level on such observation date; or
- for issuances of leveraged index-linked securities with averaging dates: the ending basket level will be the arithmetic average of the basket closing levels on the averaging dates, as calculated by the Calculation Agent.

“ending index level” with respect an issuance of leveraged index-linked securities linked to a single index will be:

- for issuances of leveraged index-linked securities with an observation date: the ending index level will be the index closing level on such observation date; or
- for issuances of leveraged index-linked securities with averaging dates: the ending index level will be the arithmetic average of the index closing levels of the underlying index on the averaging dates, as calculated by the Calculation Agent.

“Euroclear operator” means Euroclear Bank S.A./N.V., as operator of the Euroclear System.

“index business day” means, with respect to the underlying index or any basket index, a day, as determined by the Calculation Agent, on which trading is generally conducted on each relevant exchange, other than a day on which trading on any relevant exchange is scheduled to close prior to the time of the posting of its regular final weekday closing price.

“index closing level” means, on any index business day, the closing level of the underlying index or basket index or any successor index (as defined under “—Discontinuance of Any Underlying Index; Alteration of Method of Calculation” below) published at the regular weekday close of trading on that index business day. In certain

S-27

circumstances, the index closing level will be based on the alternate calculation of the underlying index or basket index described below under “—Discontinuance of Any Underlying Index; Alteration of Method of Calculation.”

“index setting date” will be the pricing date, unless otherwise specified in the applicable pricing supplement. If the index setting date specified in the applicable pricing supplement for determining the initial index level of the underlying index or any basket index is a date other than the pricing date, and such index setting date is not an index business day with respect to that underlying index or basket index or there is a market disruption event with respect to such underlying index or basket index on such day, then the index setting date for that underlying index or basket index will be postponed to the next succeeding index business day solely with respect to such underlying index or basket index on which there is no market disruption event.

“index weighting” of a basket index in an underlying basket of indices represents the percentage of the basket initially assigned to such index. The index weightings will be specified in the applicable pricing supplement.

“initial index level” for any underlying index or for any basket index means the index closing level on the index setting date, as specified in the applicable pricing supplement.

“interest payment date” for any leveraged index-linked security means a date on which, under the terms of that leveraged index-linked security, regularly scheduled interest, if any, is payable.

“issue price” means the amount per leveraged index-linked security specified in the applicable pricing supplement and will equal the principal amount of each leveraged index-linked security, unless otherwise specified.

“market disruption event” means, with respect to the underlying index or any basket index, the occurrence or existence of any of the following events, as determined by the Calculation Agent in its sole discretion:

| (i) | (a) a suspension, absence or material limitation of trading of stocks then constituting 20 percent or more of the value of the underlying index or basket index (or the successor index) on the relevant exchanges for such securities for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such relevant exchange; or
|  | (b) a breakdown or failure in the price and trade reporting systems of any relevant exchange as a result of which the reported trading prices for stocks then constituting 20 percent or more of the value of the underlying index or basket index or (or the successor index) during the last one-half hour preceding the close of the principal trading session on such relevant exchange are materially inaccurate; or
|  | (c) the suspension, material limitation or absence of trading on any major securities market for trading in futures or options contracts or exchange traded funds related to the underlying index or basket index (or the successor index) for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such market; and
| (ii) | a determination by the Calculation Agent in its sole discretion that any event described in clause (i) above materially interfered with our ability or the ability of any of our affiliates to unwind or adjust all or a material portion of the hedge position with respect to the leveraged index-linked securities.

For the purpose of determining whether a market disruption event exists at any time, if trading in a security included in the underlying index or any basket index is materially suspended or materially limited at that time, then the relevant percentage contribution of that security to the value of the underlying index or basket index shall be based on a comparison of (x) the portion of the value of the underlying index or basket index attributable to that security relative to (y) the overall value of the underlying index or basket index, in each case immediately before that suspension or limitation.

For the purpose of determining whether a market disruption event has occurred: (1) a limitation on the hours or number of days of trading will not constitute a market disruption event if it results from an announced change in the regular business hours of the relevant exchange or market, (2) a decision to permanently discontinue trading in the relevant futures or options contract or exchange traded fund will not constitute a market disruption event, (3) limitations pursuant to the rules of any relevant exchange similar to New York Stock Exchange LLC (“NYSE”)

S-28

Rule 80A (or any applicable rule or regulation enacted or promulgated by any other self-regulatory organization or any government agency of scope similar to NYSE Rule 80A as determined by the Calculation Agent) on trading during significant market fluctuations will constitute a suspension, absence or material limitation of trading, (4) a suspension of trading in futures or options contracts or exchange traded funds on an underlying index or any basket index by the primary securities market trading in such contracts or funds by reason of (a) a price change exceeding limits set by such securities exchange or market, (b) an imbalance of orders relating to such contracts or funds, or (c) a disparity in bid and ask quotes relating to such contracts or funds will constitute a suspension, absence or material limitation of trading in futures or options contracts or exchange traded funds related to the underlying index or basket index and (5) a “suspension, absence or material limitation of trading” on any relevant exchange or on the primary market on which exchange traded funds related to the underlying index or any basket index are traded will not include any time when such securities market is itself closed for trading under ordinary circumstances.

“maturity date” means the date specified in the applicable pricing supplement, subject to extension if such day is not a business day or if the scheduled observation date or the scheduled final averaging date, in the case of averaging dates, is postponed in accordance with the definition thereof. If the scheduled maturity date is not a business day, then the maturity date will be the next succeeding business day immediately following the scheduled maturity date. If the observation date or the final averaging date is postponed so that it falls less than three scheduled trading days prior to the scheduled maturity date, the maturity date will be the third scheduled trading day following the observation date or the final averaging date as postponed. See the discussion under “—Payment at Maturity—Postponement of Observation Date; Averaging Dates” below. If the applicable pricing supplement specifies that an issuance of leveraged index-linked securities will have an interest rate payment, and if the scheduled maturity date is postponed due to a market disruption event or otherwise, no interest will accrue on the leveraged index-linked securities during the period from or after the scheduled maturity date.

“maximum total return” means the maximum percentage return on the stated principal amount, if any, specified as such in the applicable pricing supplement.

“observation date” means the date specified in the applicable pricing supplement.

“original issue date” means the date specified in the applicable pricing supplement on which a particular issuance of leveraged index-linked securities will be issued.

“payment at maturity” means the payment due at maturity with respect to each leveraged index-linked security, as described under “—Payment at Maturity” below.

“pricing date” means the day when we price the leveraged index-linked securities for initial sale to the public.

“record date” for any interest payment date, if applicable, is the date 15 calendar days prior to that interest payment date, whether or not that date is a business day.

“relevant exchange” means the primary exchange(s) or market(s) of trading for (i) any security then included in any underlying index, or any successor index, and (ii) any futures or options contracts related to such underlying index or to any security then included in any underlying index.

“starting basket level” for any underlying basket of indices means the predetermined basket level specified in the applicable pricing supplement.

“stated principal amount” for an issuance of leveraged index-linked securities shall be the principal amount per leveraged index-linked security, as specified in the applicable pricing supplement.

“strike level” means the percentage of the initial index level, if any, that may be specified in the applicable pricing supplement for certain issuances of leveraged index-linked securities.

“TARGET Settlement Day” means any day on which the Trans-European Automated Real-time Gross Settlement Express Transfer System is open.

S-29

“trading day” means a day, as determined by the Calculation Agent, on which trading is generally conducted on the NYSE, the American Stock Exchange LLC (“AMEX”), The NASDAQ Stock Market LLC, the Chicago Mercantile Exchange and the Chicago Board of Options Exchange and in the over-the-counter market for equity securities in the United States.

“underlying index” or “underlying indices” means the index or indices specified in the applicable pricing supplement, the performance of which underlies the leveraged index-linked securities.

“underlying index publisher” means the publisher of the applicable underlying index.

“upside leverage factor” means the factor specified in the applicable pricing supplement.

In this “Description of Leveraged Index-Linked Securities,” references to the underlying index or a basket index will include the index or indices specified in the applicable pricing supplement and any successor index or indices, unless the context requires otherwise.

References in this prospectus supplement to “U.S. dollar,” or “U.S.$” or “$” are to the currency of the United States of America.

Other terms of the leveraged index-linked securities are described in the following paragraphs.

Payment at Maturity

At maturity, upon delivery of the leveraged index-linked securities to the Trustee, we will pay with respect to each leveraged index-linked security an amount in cash equal to:

| • | for a leveraged index-linked security without a buffer,
|  | ° | if the ending index level is greater than the initial index level, the lesser of (a) the stated principal amount plus the leveraged upside payment and (b) the stated principal amount plus the product of the stated principal amount and the maximum total return, or
|  | ° | if the ending index level is less than or equal to the initial index level, (a) the stated principal amount plus (b) the stated principal amount times the index return. Because the index return will be less than or equal to 0, this payment will be less than or equal to the stated principal amount.

OR

| • | for a leveraged index-linked security with a buffer,
|  | ° | if the ending index level is greater than the initial index level, the lesser of (a) the stated principal amount plus the leveraged upside payment and (b) the stated principal amount plus the product of the stated principal amount and the maximum total return, or
|  | ° | if the ending index level is less than or equal to the initial index level, but has declined by an amount less than or equal to the buffer amount, the stated principal amount, or
|  | ° | if the ending index level is less than the initial index level, and has declined by an amount greater than the buffer amount, the stated principal amount plus the downside buffer payment. Because the downside buffer payment will be less than 0, this payment will be less than the stated principal amount.

S-30

| where, |

| • | for a leveraged index-linked security linked to a basket of indices without a buffer,
|  | ° | if the ending basket level is greater than the starting basket level, the lesser of (a) the stated principal amount plus the leveraged upside payment and (b) the stated principal amount plus the product of the stated principal amount and the maximum total return, or
|  | ° | if the ending basket level is less than or equal to the starting basket level, (a) the stated principal amount plus (b) the stated principal amount times the basket return. Because the basket return will be less than or equal to 0, this payment will be less than or equal to the stated principal amount.

OR

| • | for a leveraged index-linked security linked to a basket of indices with a buffer,
|  | ° | if the ending basket level is greater than the starting basket level, the lesser of (a) the stated principal amount plus the leveraged upside payment and (b) the stated principal amount plus the product of the stated principal amount and the maximum total return, or
|  | ° | if the ending basket level is less than or equal to the starting basket level, but has declined by an amount less than or equal to the buffer amount, the stated principal amount, or
|  | ° | if the ending basket level is less than the starting basket level, and has declined by an amount greater than the buffer amount, the stated principal amount plus the downside buffer payment. Because the downside buffer payment will be less than 0, this payment will be less than the stated principal amount.
| where, |  |

Postponement of Observation Date; Averaging Dates. The Calculation Agent will take into account market disruption events and non-index business days in any calculation of the ending index level as follows:

> For issuances of leveraged index-linked securities linked to a single index: If a market disruption event with respect to such underlying index occurs on the scheduled observation date or on any scheduled averaging date or if the scheduled observation date or any such scheduled averaging date is not an index business day, the

S-31

> index closing level for such scheduled observation date or averaging date will be determined on the immediately succeeding index business day on which no market disruption event shall have occurred; provided that the index closing level will not be determined on a date later than the tenth scheduled index business day after the scheduled observation date or final averaging date, as applicable, and if such date is not an index business day, or if there is a market disruption event on such date, the Calculation Agent will determine the ending index level on such date in accordance with the formula for calculating the underlying index last in effect prior to the commencement of the market disruption event (or prior to the non-index business day), without rebalancing or substitution, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the closing price that would have prevailed but for such suspension, limitation or non-index business day) on such date of each security most recently constituting the underlying index.

> For issuances of leveraged index-linked securities linked to a basket of indices: If a market disruption event with respect to any basket index occurs on the scheduled observation date or on any scheduled averaging date or if the scheduled observation date or any scheduled averaging date is not an index business day with respect to such basket index, the index closing level (solely with respect to such affected basket index) will be determined on the immediately succeeding index business day on which no market disruption event shall have occurred with respect to such affected basket index, and the basket closing level for such scheduled observation date or averaging date shall be determined on the later of such date as so postponed and the date on which the index closing level for each of the basket indices is available; provided that the basket closing level will not be determined on a date later than the tenth scheduled index business day after the scheduled observation date or final averaging date, as applicable, and if such date is not an index business day or if there is a market disruption event on such date, in each case, with respect to any basket index for which an index closing level has not been determined, the Calculation Agent will determine the basket closing level using the index closing level of any affected basket index as determined by the Calculation Agent in accordance with the formula for calculating such index last in effect prior to the commencement of the market disruption event (or prior to the non-index business day), without rebalancing or substitution, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the closing price that would have prevailed but for such suspension, limitation or non-index business day) on such date of each security most recently constituting such affected basket index.

We shall, or shall cause the Calculation Agent to, (i) provide written notice to the Trustee and to The Depository Trust Company, which we refer to as DTC, of the amount of cash to be delivered with respect to the stated principal amount of each leveraged index-linked security, on or prior to 10:30 a.m. on the trading day preceding the maturity date (but if such trading day is not a business day, prior to the close of business on the business day preceding the maturity date), and (ii) deliver the aggregate cash amount due with respect to the leveraged index-linked securities to the Trustee for delivery to DTC, as holder of the leveraged index-linked securities, on the maturity date. We expect such amount of cash will be distributed to investors on the maturity date in accordance with the standard rules and procedures of DTC and its direct and indirect participants. See “—Form of Securities—Book Entry Securities” “—Form of Securities—Certificated Securities” below, and see “The Depositary” in the accompanying prospectus supplement.

Postponement of Maturity. If the scheduled observation date or final averaging date is postponed, as described above, to a date later than the third scheduled trading day prior to the scheduled maturity date, the maturity date of the notes will be postponed until the third scheduled trading day following that observation date or final averaging date, in the case of averaging dates, as postponed.

Trustee

The “Trustee” for each offering of leveraged index-linked securities issued under our Senior Debt Indenture will be The Bank of New York, a New York banking corporation (as successor to JPMorgan Chase Bank, N.A.).

Agent

The “agents” for each underwritten offering of leveraged index-linked securities will be specified in the applicable pricing supplement.

S-32

Calculation Agent and Calculations

The “Calculation Agent” for the leveraged index-linked securities will be MS & Co. As Calculation Agent, MS & Co. will determine the initial index level, the index closing level, the ending index level, the starting basket level, the ending basket level, the basket closing level, the index return, the basket return and the payment at maturity.

All determinations made by the Calculation Agent will be at the sole discretion of the Calculation Agent and will, in the absence of manifest error, be conclusive for all purposes and binding on you, the Trustee and us.

All calculations with respect to the payment at maturity, if any, will be made by the Calculation Agent and will be rounded to the nearest one billionth, with five ten-billionths rounded upward (e.g., .9876543215 would be rounded to .987654322); all dollar amounts related to determination of the amount of cash payable per leveraged index-linked security will be rounded to the nearest ten-thousandth, with five one hundred-thousandths rounded upward (e.g., .76545 would be rounded up to .7655); and all dollar amounts paid on the aggregate number of leveraged index-linked securities will be rounded to the nearest cent, with one-half cent rounded upward.

Because the Calculation Agent is our affiliate, the economic interests of the Calculation Agent and its affiliates may be adverse to your interests, as an owner of the leveraged index-linked securities, including with respect to certain determinations and judgments that the Calculation Agent must make in determining the index return (or basket return), the ending index level (or ending basket level), the payment at maturity or whether a market disruption event has occurred. See “Discontinuance of Any Underlying Index; Alteration of Method of Calculation”, and the definition of market disruption event under “—General Terms of Leveraged Index-Linked Securities—Some Definitions.” MS & Co., as a registered broker-dealer, is required to maintain policies and procedures regarding the handling and use of confidential proprietary information, and such policies and procedures will be in effect throughout the term of the leveraged index-linked securities to restrict the use of information relating to the calculation of the ending index level (or ending basket level) prior to the dissemination of such information. MS & Co. is obligated to carry out its duties and functions as Calculation Agent in good faith and using its reasonable judgment.

Alternate Exchange Calculation in Case of an Event of Default

In case an event of default with respect to the leveraged index-linked securities shall have occurred and be continuing, the amount declared due and payable per leveraged index-linked security upon any acceleration of the leveraged index-linked securities (an “Event of Default Acceleration”) shall be determined by the Calculation Agent and shall be an amount in cash equal to the payment at maturity calculated using the index closing level as of the date of such acceleration as the ending index level, plus, if applicable, any accrued but unpaid interest as of the date of such acceleration.

If the maturity of the leveraged index-linked securities is accelerated because of an event of default as described above, we shall, or shall cause the Calculation Agent to, provide written notice to the Trustee at its New York office, on which notice the Trustee may conclusively rely, and to DTC of the cash amount due with respect to the leveraged index-linked securities as promptly as possible and in no event later than two business days after the date of acceleration.

Discontinuance of Any Underlying Index; Alteration of Method of Calculation

If any underlying index publisher discontinues publication of the underlying index or a basket index and such underlying index publisher or another entity (including MS & Co.) publishes a successor or substitute index that MS & Co., as the Calculation Agent, determines, in its sole discretion, to be comparable to the discontinued underlying index or basket index (such index being referred to herein as a “successor index”), then any subsequent index closing level will be determined by reference to the published value of such successor index at the regular weekday close of trading on the index business day that any index closing level is to be determined.

Upon any selection by the Calculation Agent of a successor index, the Calculation Agent will cause written notice thereof to be furnished to the Trustee, to Morgan Stanley and to DTC, as holder of the leveraged index-linked

S-33

securities, within three trading days of such selection. We expect that such notice will be passed on to you, as a beneficial owner of the leveraged index-linked securities, in accordance with the standard rules and procedures of DTC and its direct and indirect participants.

If any underlying index publisher discontinues publication of the underlying index or a basket index prior to, and such discontinuance is continuing on, the observation date or the date of acceleration and MS & Co., as the Calculation Agent, determines, in its sole discretion, that no successor index is available at such time, then the Calculation Agent will determine the index closing level for such observation date or date of acceleration. The index closing level will be computed by the Calculation Agent in accordance with the formula for and method of calculating the underlying index or basket index last in effect prior to such discontinuance, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the closing price that would have prevailed but for such suspension or limitation) at the close of the principal trading session of the relevant exchange on such observation date or date of acceleration of each security most recently constituting such underlying index or basket index without any rebalancing or substitution of such securities following such discontinuance. Notwithstanding these alternative arrangements, discontinuance of the publication of the underlying index or basket index may adversely affect the value of the leveraged index-linked securities.

If at any time the method of calculating the underlying index or a basket index or a successor index, or the value thereof, is changed in a material respect, or if such underlying index or basket index or a successor index is in any other way modified so that such index does not, in the opinion of MS & Co., as the Calculation Agent, fairly represent the value of the underlying index or basket index or such successor index had such changes or modifications not been made, then, from and after such time, the Calculation Agent will, at the close of business in New York City on each date on which the index closing level is to be determined, make such calculations and adjustments as, in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a value of a stock index comparable to the underlying index or basket index or such successor index, as the case may be, as if such changes or modifications had not been made, and the Calculation Agent will calculate the ending index level with reference to the underlying index or basket index or such successor index, as adjusted. Accordingly, if the method of calculating the underlying index or basket index or a successor index is modified so that the value of such index is a fraction of what it would have been if it had not been modified (e.g., due to a split in the index), then the Calculation Agent will adjust such index in order to arrive at a value of the underlying index or basket index or such successor index as if it had not been modified (e.g., as if such split had not occurred).

Forms of Securities

As noted above, leveraged index-linked securities are issued as part of our Series F medium-term note program. We will issue leveraged index-linked securities only in fully registered form either as book-entry securities or as certificated securities. References to “holders” mean those who own securities registered in their own names, on the books that we or the Trustee maintain for this purpose, and not those who own beneficial interests in securities registered in street name or in leveraged index-linked securities issued in book-entry form through one or more depositaries.

Book-Entry Securities. For securities in book-entry form, we will issue one or more global certificates representing the entire issue of securities. Except as set forth in the prospectus under “Forms of Securities—Global Securities,” you may not exchange book-entry securities or interests in book-entry securities for certificated securities.

Each global security certificate representing book-entry securities will be deposited with, or on behalf of, the Depositary and registered in the name of the Depositary or a nominee of the Depositary. These certificates name the Depositary or its nominee as the owner of the securities. The Depositary maintains a computerized system that will reflect the interests held by its participants in the global securities. An investor’s beneficial interest will be reflected in the records of the Depositary’s direct or indirect participants through an account maintained by the investor with its broker/dealer, bank, trust company or other representative. A further description of the Depositary’s procedures for global leveraged index-linked securities representing book-entry securities is set forth under “Forms of Securities—The Depositary” in the prospectus. The Depositary has confirmed to us, the agents and each Trustee that it intends to follow these procedures.

S-34

Certificated Securities. If we issue securities in certificated form, the certificate will name the investor or the investor’s nominee as the owner of the security. The person named in the security register will be considered the owner of the security for all purposes under the Senior Debt Indenture. For example, if we need to ask the holders of any issuance of securities to vote on a proposed amendment to such securities, the person named in the security register will be asked to cast any vote regarding that issuance of securities. If you have chosen to have some other entity hold the certificates for you, that entity will be considered the owner of your security in our records and will be entitled to cast the vote regarding your security. You may not exchange certificated securities for book-entry securities or interests in book-entry securities.

New York Law to Govern. The leveraged index-linked securities will be governed by, and construed in accordance with, the laws of the State of New York.

Interest and Principal Payments

You should read the section called “Description of Debt Securities” in the prospectus, where we describe generally how principal and interest payments, if any, on the leveraged index-linked securities are made, how exchanges and transfers of the leveraged index-linked securities are effected and how fixed and floating rates of interest on the leveraged index-linked securities, if any, are calculated.

S-35

USE OF PROCEEDS AND HEDGING

The net proceeds we receive from the sale of the leveraged index-linked securities will be used for general corporate purposes and, in part, in connection with hedging our obligations under the leveraged index-linked securities through one or more of our subsidiaries. See also “Use of Proceeds” in the accompanying prospectus. The original issue price of the leveraged index-linked securities includes the agent’s commissions (as shown on the cover page of the applicable pricing supplement) paid with respect to the leveraged index-linked securities and the cost of hedging our obligations thereunder. The cost of hedging includes the projected profit that our subsidiaries expect to realize in consideration for assuming the risks inherent in managing the hedging transactions. Since hedging our obligations entails risk and may be influenced by market forces beyond our or our subsidiaries’ control, such hedging may result in a profit that is more or less than initially projected, or could result in a loss. See also “Use of Proceeds” in the accompanying prospectus.

On or prior to the day we price the leveraged index-linked securities for initial sale to the public, we, through our subsidiaries or others, expect to hedge our anticipated exposure in connection with the leveraged index-linked securities by taking positions in the stocks constituting the underlying index or indices, in futures or options contracts on the underlying index or indices or its component stocks listed on major securities markets or positions in any other available securities or instruments that we may wish to use in connection with such hedging. Such purchase activity could increase the value of the underlying index or indices, and therefore the value at which the underlying index or indices must close on the observation date or on the averaging dates before you would receive at maturity a payment that exceeds the principal amount of the leveraged index-linked securities. In addition, through our subsidiaries, we are likely to modify our hedge position throughout the life of the leveraged index-linked securities, including on the observation date or averaging dates, by purchasing and selling the stocks constituting the underlying index or indices, futures or options contracts on the underlying index or indices or its component stocks listed on major securities markets or positions in any other available securities or instruments that we may wish to use in connection with such hedging activities, including by selling any such securities or instruments on the observation date or on the specified averaging dates. We cannot give any assurance that our hedging activities will not affect the value of the underlying index or indices and, therefore, adversely affect the value of the leveraged index-linked securities or the payment you will receive at maturity.

LEVERAGED INDEX-LINKED SECURITIES OFFERED ON A GLOBAL BASIS

If we offer the leveraged index-linked securities on a global basis, we will so specify in the applicable pricing supplement. The additional information contained in the prospectus under “Securities Offered on a Global Basis through the Depositary,” “—Book-Entry, Delivery and Form” and “—Global Clearance and Settlement Procedures” will apply to every offering on a global basis. The additional provisions described under “Securities Offered on a Global Basis through the Depositary”, “—Tax Redemption” and “—Payment of Additional Amounts” will apply to leveraged index-linked securities offered on a global basis only if we so specify in the applicable pricing supplement.

ERISA

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 leveraged index-linked securities. 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 subsidiaries and affiliates, including MS & Co. and Morgan Stanley DW Inc. (formerly Dean Witter Reynolds Inc.) (“MSDWI”), may be each 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 (also “Plans”). Prohibited transactions within the meaning of ERISA or the Code would likely arise, for example, if the leveraged index-linked securities are acquired by or with the assets of a Plan with respect to which MS & Co., MSDWI or any of their affiliates is a service provider or other party in interest, unless the leveraged index-linked

S-36

securities 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 such 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 leveraged index-linked securities. 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 asset managers). In addition, ERISA Section 408(b)(17) provides an exemption for the purchase and sale of securities and related lending transactions, provided that neither the issuer of the securities nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Plan involved in the transaction, and provided further that the Plan pays no more than “adequate consideration” (to be defined in regulations to be issued by the Secretary of the Department of Labor) in connection with the transaction (the so-called “service provider” exemption).

Because we may be considered a party in interest with respect to many Plans, the leveraged index-linked securities 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 leveraged index-linked securities will be deemed to have represented, in its corporate and its fiduciary capacity, by its purchase and holding of the leveraged index-linked securities that either (a) it is not a Plan or a Plan Asset Entity and is not purchasing such leveraged index-linked securities on behalf of or with “plan assets” of any Plan, or with any assets of a governmental or church plan that is subject to any federal, state or local law that is substantially similar to the provisions of Section 406 of ERISA of Section 4975 of the Code or (b) its purchase, holding and disposition are eligible for exemptive relief or such purchase, holding and disposition are not prohibited by ERISA or Section 4975 of the Code (or in the case of a governmental or church plan, any substantially similar federal, state or local law).

Under ERISA, assets of a Plan may include assets of certain commingled vehicles and entities in which the Plan has invested (including, in certain cases, the general account of an insurance company). Accordingly, commingled vehicles and entities which include assets of a Plan must ensure that one of the foregoing exemptions is available. 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 leveraged index-linked securities on behalf of or with “plan assets” of any Plan consult with their counsel regarding the availability of exemptive relief under any available exemptions, such as PTCEs 96-23, 95-60, 91-38, 90-1 or 84-14 or the service provider exemption.

Purchasers of the leveraged index-linked securities have exclusive responsibility for ensuring that their purchase, holding and disposition of the leveraged index-linked securities do not violate the prohibited transaction rules of ERISA or the Code or similar regulations applicable to governmental or church plans, as described above. The sale of any leveraged index-linked securities to any Plan investor 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 Plan investors generally or any particular Plan investor, or that such an investment is appropriate for Plan investors generally or any particular Plan investor.

S-37

UNITED STATES FEDERAL TAXATION

In the opinion of Davis Polk & Wardwell, our counsel (“Tax Counsel”), the following are the material U.S. federal tax consequences of ownership and disposition of the leveraged index-linked securities.

The discussion below assumes that the leveraged index-linked securities will not pay any stated interest. The U.S. federal tax consequences of investing in leveraged index-linked securities which will pay stated interest will be set forth in the applicable pricing supplement.

This discussion only applies to initial investors in the leveraged index-linked securities who:

- purchase the leveraged index-linked securities at their “issue price”; and
- will hold the leveraged index-linked securities as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”).

Subject to any additional discussion under the applicable pricing supplement, it is expected, and the discussion below assumes, that, for U.S. federal income tax purposes, the issue price of a leveraged index-linked security is equal to its stated issue price indicated in the applicable pricing supplement.

This discussion does not describe all of the tax consequences that may be relevant to a particular holder in light of the holder’s particular circumstances or to holders subject to special rules, such as:

- certain financial institutions;
- insurance companies;
- dealers in securities or foreign currencies;
- investors holding the leveraged index-linked securities as part of a hedging transaction, “straddle”, conversion transaction, or integrated transaction or holding the securities as part of a constructive sale transaction;
- U.S. Holders, as defined below, whose functional currency is not the U.S. dollar;
- partnerships or other entities classified as partnerships for U.S. federal income tax purposes;
- regulated investment companies;
- real estate investment trusts;
- tax exempt entities, including an “individual retirement account” or “Roth IRA” as defined in Section 408 or 408A of the Code, respectively;
- persons subject to the alternative minimum tax;
- nonresident alien individuals who have lost their U.S. citizenship or who have ceased to be taxed as U.S. resident aliens; and
- Non-U.S. Holders, as defined below, for whom income or gain in respect of the leveraged index-linked securities is effectively connected with a trade or business in the United States.

As the law applicable to the U.S. federal income taxation of instruments such as the leveraged index-linked securities is technical and complex, the discussion below necessarily represents only a general summary. Moreover, the effect of any applicable state, local or foreign tax laws is not discussed.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein. Persons considering the purchase of the leveraged index-linked securities are urged to consult their tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

This discussion is subject to any additional discussion regarding U.S. federal income taxation contained in the applicable pricing supplement. Accordingly, you should also consult the applicable pricing supplement for any additional discussion regarding U.S. federal income taxation with respect to the specific leveraged index-linked securities offered thereunder.

S-38

General

Except as otherwise provided in the applicable pricing supplement and based on certain assumptions and representations that will be confirmed at or prior to the pricing date with respect to each offering, it is reasonable to treat the leveraged index-linked securities as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. Due to the absence of statutory, judicial or administrative authorities that directly address the characterization or treatment of the leveraged index-linked securities or instruments that are similar to the leveraged index-linked securities for U.S. federal income tax purposes, no assurance can be given that the IRS or the courts will agree with the characterization and tax treatment described herein. You are urged to consult your own tax advisors regarding all aspects of the U.S. federal tax consequences of an investment in the leveraged index-linked securities (including alternative characterizations of the leveraged index-linked securities) and with respect to any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. Unless otherwise stated, the following discussion is based on the characterization and treatment of the leveraged index-linked securities described above.

Tax Consequences to U.S. Holders

As used herein, the term “U.S. Holder” means beneficial owner of a leveraged index-linked security that is for U.S. federal income tax purposes:

| • | a citizen or resident of the United States;
| • | a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any political subdivision thereof; or
| • | an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

The term U.S. Holder also includes certain former citizens and residents of the United States.

Tax Treatment of the Leveraged Index-Linked Securities

Except as otherwise provided in the applicable pricing supplement and assuming the characterization of the leveraged index-linked securities as set forth above is respected, the following U.S. federal income tax consequences should result.

Tax Treatment Prior to Maturity. A U.S. Holder should not be required to recognize taxable income over the term of the leveraged index-linked securities prior to maturity, other than pursuant to a sale or exchange as described below.

Tax Basis. A U.S. Holder’s tax basis in the leveraged index-linked securities should equal the amount paid by the U.S. Holder to acquire the leveraged index-linked securities.

Sale, Exchange or Settlement of the Leveraged Index-Linked Securities. Upon a sale or exchange of the leveraged index-linked securities, or upon settlement of the leveraged index-linked securities at maturity, a U.S. Holder should generally recognize gain or loss equal to the difference between the amount realized on the sale, exchange or settlement and the U.S. Holder’s tax basis in the leveraged index-linked securities sold, exchanged, or settled. Any capital gain or loss recognized upon sale, exchange or settlement of a leveraged index-linked security should be long-term capital gain or loss if the U.S. Holder has held the leveraged index-linked securities for more than one year at such time.

Possible Alternative Tax Treatments of an Investment in the Leveraged Index-Linked Securities

Due to the absence of authorities that directly address the proper characterization of the leveraged index-linked securities, no assurance can be given that the IRS will accept, or that a court will uphold, the characterization and treatment described above. In particular, with respect to a leveraged index-linked security that matures (after taking into account the last possible date that the leveraged index-linked securities could be outstanding under the terms of

S-39

the leveraged index-linked securities) more than one year from its date of issuance, the IRS could seek to analyze the U.S. federal income tax consequences of owning a leveraged index-linked security under Treasury regulations governing contingent payment debt instruments (the “Contingent Debt Regulations”).

If the IRS were successful in asserting that the Contingent Debt Regulations applied to the leveraged index-linked securities, the timing and character of income thereon would be significantly affected. Among other things, a U.S. Holder would be required to accrue original issue discount on the leveraged index-linked securities every year at a “comparable yield” determined at the time of their issuance. Furthermore, any gain realized by a U.S. Holder at maturity or upon a sale or other disposition of the leveraged index-linked securities would generally be treated as ordinary income, and any loss realized at maturity would be treated as ordinary loss to the extent of the U.S. Holder’s prior accruals of original issue discount, and as capital loss thereafter.

Even if the Contingent Debt Regulations do not apply to the leveraged index-linked securities, other alternative federal income tax characterizations of the leveraged index-linked securities are also possible, which if applied could also affect the timing and character of the income or loss with respect to the leveraged index-linked securities. It is possible, for example, that a leveraged index-linked security could be treated as a unit consisting of a loan and a forward contract, in which case a U.S. Holder would be required to accrue original issue discount as income on a current basis. Accordingly, prospective investors are urged to consult their own tax advisors regarding all aspects of the U.S. federal income tax consequences of an investment in the leveraged index-linked securities.

Backup Withholding and Information Reporting

Backup withholding may apply in respect of the amounts paid to a U.S. Holder, unless such U.S. Holder provides proof of an applicable exemption or a correct taxpayer identification number, or otherwise complies with applicable requirements of the backup withholding rules. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the U.S. Holder’s U.S. federal income tax liability, provided that the required information is furnished to the IRS. In addition, information returns will be filed with the IRS in connection with payments on the leveraged index-linked securities and the proceeds from a sale or other disposition of the leveraged index-linked securities, unless the U.S. Holder provides proof of an applicable exemption from the information reporting rules.

Tax Consequences to Non-U.S. Holders

This section only applies to Non-U.S. Holders. As used herein, the term “Non-U.S. Holder” means a beneficial owner of a leveraged index-linked security issued under this prospectus supplement that is for U.S. federal income tax purposes:

- an individual who is classified as a nonresident alien;
- a foreign corporation; or
- a foreign trust or estate.

“Non-U.S. Holder” does not include a holder who is an individual present in the United States for 183 days or more in the taxable year of disposition and who is not otherwise a resident of the United States for U.S. federal income tax purposes. Such holder is urged to consult his or her own tax advisors regarding the U.S. federal income tax consequences of the sale, exchange or other disposition of a leveraged index-linked security.

Tax Treatment upon Sale, Exchange or Settlement of a Leveraged Index-Linked Security

In general. Except as otherwise provided in the applicable pricing supplement and assuming the characterization of the leveraged index-linked securities as set forth above is respected, a Non-U.S. Holder of the leveraged index-linked securities will not be subject to U.S. federal income or withholding tax in respect of amounts paid to the Non-U.S. Holder.

If all or any portion of a leveraged index-linked security were recharacterized as a debt instrument, any payment made to a Non-U.S. Holder with respect to the leveraged index-linked securities would not be subject to U.S. federal withholding tax, provided that:

S-40

- the Non-U.S. Holder does not own, directly or by attribution, ten percent or more of the total combined voting power of all classes of our stock entitled to vote;
- the Non-U.S. Holder is not a controlled foreign corporation related, directly or indirectly, to us through stock ownership;
- the Non-U.S. Holder is not a bank receiving interest under section 881(c)(3)(A) of the Code; and
- the certification requirement described below has been fulfilled with respect to the beneficial owner.

Certification Requirement. The certification requirement referred to in the preceding paragraph will be fulfilled if the beneficial owner of a leveraged index-linked security (or a financial institution holding the leveraged index-linked securities on behalf of the beneficial owner) furnishes to us an IRS Form W-8BEN, in which the beneficial owner certifies under penalties of perjury that it is not a U.S. person.

U.S. Federal Estate Tax

Individual Non-U.S. Holders and entities the property of which is potentially includible in such an individual’s gross estate for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, the leveraged index-linked securities are likely to be treated as U.S. situs property subject to U.S. federal estate tax. Prospective investors that are non-U.S. individuals, or are entities of the type described above, are urged to consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in the leveraged index-linked securities.

Backup Withholding and Information Reporting

Information returns may be filed with the IRS in connection with the payment on the leveraged index-linked securities at maturity as well as in connection with the proceeds from a sale, exchange or other disposition. A Non-U.S. Holder may be subject to backup withholding in respect of amounts paid to the Non-U.S. Holder, unless such Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person for U.S. federal income tax purposes or otherwise establishes an exemption. The certification procedures described above under “—Tax Treatment upon Sale, Exchange or Settlement of a Leveraged Index-Linked Security — Certification Requirement” will satisfy the certification requirements necessary to avoid the backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is furnished to the IRS.

S-41

PLAN OF DISTRIBUTION

We are offering the leveraged index-linked securities as part of our Series F medium-term notes on a continuing basis through Morgan Stanley & Co. Incorporated and Morgan Stanley DW Inc., which we refer to individually as an “agent” and together as the “agents.” We also expect to use other agents that will be named in the applicable pricing supplement. Each agent has, or will have, agreed to use reasonable efforts to solicit offers to purchase these securities. We will have the sole right to accept offers to purchase these securities and may reject any offer in whole or in part. Each agent may reject, in whole or in part, any offer it solicited to purchase securities. We will pay an agent, in connection with sales of these leveraged index-linked securities resulting from a solicitation that agent made or an offer to purchase that agent received, a commission that will be specified in the applicable pricing supplement.

We may also sell these securities to an agent as principal for its own account at discounts to be agreed upon at the time of sale within the range of the commissions stated above or as otherwise disclosed in the applicable pricing supplement. That agent may resell these securities to investors and other purchasers at a fixed offering price or at prevailing market prices, or prices related thereto at the time of resale or otherwise, as that agent determines and as we will specify in the applicable pricing supplement. An agent may offer the securities it has purchased as principal to other dealers, which may include Morgan Stanley & Co. International Limited and Bank Morgan Stanley AG. That agent may sell the securities to any dealer at a discount and, unless otherwise specified in the applicable pricing supplement, the discount allowed to any dealer will not be in excess of the discount that agent will receive from us. After the initial public offering of securities that an agent is to resell on a fixed public offering price basis, the agent may change the public offering price, concession and discount.

Each of the agents may be deemed to be an “underwriter” within the meaning of the Securities Act of 1933, as amended. We and the agents have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act, or to contribute to payments made in respect of those liabilities. We have also agreed to reimburse the agents for specified expenses.

We estimate that we will spend approximately $5,070,500 for printing, rating agency, Trustee’s and legal fees and other expenses allocable to the offering of the Series F medium term notes, including the leveraged index-linked securities, and the other securities registered on our shelf registration statement and estimate that we will spend corresponding amounts with respect to any additional securities that we may register on our shelf registration statement subsequent to our initial filing.

Unless otherwise provided in the applicable pricing supplement, we do not intend to apply for the listing of these leveraged index-linked securities on a national securities exchange, but have been advised by the agents that they intend to make a market in these leveraged index-linked securities as applicable laws and regulations permit. The agents are not obligated to do so, however, and the agents may discontinue making a market at any time without notice. No assurance can be given as to the liquidity of any trading market for these leveraged index-linked securities.

Morgan Stanley & Co. Incorporated and Morgan Stanley DW Inc. are our wholly-owned subsidiaries. Each agent that is an NASD member will conduct each offering of these securities in compliance with the requirements of Rule 2720 of the NASD regarding an NASD member firm’s distributing the securities of an affiliate. Following the initial distribution of these leveraged index-linked securities, each agent may offer and sell those leveraged index-linked securities in the course of its business as a broker-dealer. An agent may act as principal or agent in those transactions and will make any sales at varying prices related to prevailing market prices at the time of sale or otherwise. Morgan Stanley & Co. Incorporated and Morgan Stanley DW Inc. may use this prospectus supplement in connection with any of those transactions. The agents are not obligated to make a market in any of these leveraged index-linked securities and may discontinue any market-making activities at any time without notice.

No agent or dealer that is an NASD member utilized in the initial offering of these securities will confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

S-42

In order to facilitate the offering of these leveraged index-linked securities, the agents may engage in transactions that stabilize, maintain or otherwise affect the price of these leveraged index-linked securities or of the securities that constitute the underlying index or indices. Specifically, the agents may sell more leveraged index-linked securities than they are obligated to purchase in connection with the offering, creating a naked short position for their own accounts. The agents must close out any naked short position by purchasing leveraged index-linked securities in the open market. A naked short position is more likely to be created if the agents are concerned that there may be downward pressure on the price of these leveraged index-linked securities in the open market after pricing that could adversely affect investors who purchase in the offering. As an additional means of facilitating the offering, the agents may bid for, and purchase, these leveraged index-linked securities or the securities that constitute the underlying index or indices in the open market to stabilize the price of these leveraged index-linked securities or of such underlying securities. Finally, in any offering of the leveraged index-linked securities through a syndicate of underwriters or dealer group, the agent acting on behalf of the underwriting syndicate or for itself may also reclaim selling concessions allowed to an underwriter or a dealer for distributing these leveraged index-linked securities in the offering, if the agent repurchases previously distributed leveraged index-linked securities to cover syndicate short positions, to stabilize the price of these leveraged index-linked securities or otherwise. Any of these activities may raise or maintain the market price of these leveraged index-linked securities above independent market levels or prevent or retard a decline in the market price of these leveraged index-linked securities. The agents are not required to engage in these activities, and may end any of these activities at any time.

Concurrently with the offering of these leveraged index-linked securities through the agents, we may issue other debt securities under the indenture referred to in this prospectus supplement similar to those described in this prospectus supplement. Those debt securities may include other Series F medium-term notes and medium-term notes under our Series G and Series H prospectus supplement, which we refer to as “Euro medium-term notes.” The other Series F medium-term notes and the Euro medium-term notes may have terms substantially similar to the terms of the leveraged index-linked securities offered under this prospectus supplement. The Euro medium-term notes may be offered concurrently with the offering of these leveraged index-linked securities, on a continuing basis outside the United States by us, under a distribution agreement with Morgan Stanley & Co. International Limited, as agent for us. The terms of that distribution agreement, which we refer to as the Euro Distribution Agreement, are substantially similar to the terms of the distribution agreement for a U.S. offering, except for selling restrictions specified in the Euro Distribution Agreement.

We expect the agent or an affiliate of ours will enter into a hedging transaction with us in connection with each offering of leveraged index-linked securities. See “Use of Proceeds and Hedging” above.

With respect to each issuance of leveraged index-linked securities, we expect to deliver the leveraged index-linked securities against payment therefor in New York, New York on the original issue date (settlement date) specified in the applicable pricing supplement. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the original issue date for any issuance of leveraged index-linked securities is more than three business days after the pricing date, purchasers who wish to trade leveraged index-linked securities more than three business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

Index-Linked Securities Offered outside the United States

If any of our leveraged index-linked securities are offered outside the United States, those securities will be offered for sale in those jurisdictions outside of the United States where it is legal to make offers for sale of those securities.

Each of the agents has represented and agreed, and any other agent through which we may offer any leveraged index-linked securities on a global basis will represent and agree, that it will comply with all applicable laws and regulations in force in any jurisdiction in which it purchases, offers, sells or delivers the securities or possesses or distributes the applicable pricing supplement, this prospectus supplement or the accompanying prospectus and will obtain any consent, approval or permission required by it for the purchase, offer or sale by it of the securities under the laws and regulations in force in any jurisdiction to which it is subject or in which it makes purchases, offers or

S-43

sales of the securities, and we shall not have responsibility for the agent’s compliance with the applicable laws and regulations or obtaining any required consent, approval or permission.

With respect to sales in any jurisdictions outside of the United States of such securities, purchasers of any such securities may be required to pay stamp taxes and other charges in accordance with the laws and practices of the country of purchase in addition to the issue price set forth on the cover page hereof.

General

No action has been or will be taken by us, the agents or any dealer that would permit a public offering of the leveraged index-linked securities or possession or distribution of any pricing supplement or this prospectus supplement or the accompanying prospectus in any jurisdiction, other than the United States, where action for that purpose is required. No offers, sales or deliveries of the leveraged index-linked securities, or distribution of any pricing supplement or this prospectus supplement and the accompanying prospectus or any other offering material relating to the leveraged index-linked securities, may be made in or from any jurisdiction except in circumstances which will result in compliance with any applicable laws and regulations and will not impose any obligations on us, any agent or any dealer.

The agents have represented and agreed, and each dealer through which we may offer the leveraged index-linked securities has represented and agreed, that it (i) will comply with all applicable laws and regulations in force in each non-U.S. jurisdiction in which it purchases, offers, sells or delivers the leveraged index-linked securities or possesses or distributes any pricing supplement, this prospectus supplement and the accompanying prospectus and (ii) will obtain any consent, approval or permission required by it for the purchase, offer or sale by it of the leveraged index-linked securities under the laws and regulations in force in each non-U.S. jurisdiction to which it is subject or in which it makes purchases, offers or sales of the leveraged index-linked securities. We shall not have responsibility for any agent’s or any dealer’s compliance with the applicable laws and regulations or obtaining any required consent, approval or permission.

Argentina

The leveraged index-linked securities are not and will not be authorized by the Comisión Nacional de Valores for public offer in Argentina and may thus not be offered or sold to the public at large or to sectors or specific groups thereof by any means, including but not limited to personal offerings, written materials, advertisements or the media, in circumstances which constitute a public offering of securities under Argentine Law No. 17,811, as amended.

Brazil

The leveraged index-linked securities have not been and will not be registered with the Comissão de Calores Mobiliários (The Brazilian Securities Commission). The leveraged index-linked securities may not be offered or sold in the Federative Republic of Brazil (“Brazil”) except in circumstances which do not constitute a public offering or distribution under Brazilian laws and regulations.

Chile

The leveraged index-linked securities have not been registered with the Superintendencia de Valores y Seguros in Chile and may not be offered or sold publicly in Chile. No offer, sales or deliveries of the leveraged index-linked securities or distribution of this prospectus supplement or the accompanying prospectus, may be made in or from Chile except in circumstances which will result in compliance with any applicable Chilean laws and regulations.

Hong Kong

No action has been taken to permit an offering of the leveraged index-linked securities to the public in Hong Kong as the leveraged index-linked securities have not been authorized by the Securities and Futures Commission of Hong Kong and, accordingly, no advertisement, invitation or document relating to the leveraged index-linked securities, whether in Hong Kong or elsewhere, shall be issued, circulated or distributed which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong other than (i) with respect to the

S-44

leveraged index-linked securities which are or are intended to be disposed of only to persons outside Hong Kong or only to professional investors within the meaning of the Securities and Futures Ordinance (Cap. 571) of Hong Kong ("SFO") and any rules made thereunder or (ii) in circumstances that do not constitute an invitation to the public for the purposes of the SFO.

Mexico

The leveraged index-linked securities have not been registered with the National Registry of Securities maintained by the Mexican National Banking and Securities Commission and may not be offered or sold publicly in Mexico. This prospectus supplement and the accompanying prospectus may not be publicly distributed in Mexico.

Singapore

The agent and each dealer represent and agree that they will not offer or sell the leveraged index-linked securities nor make the leveraged index-linked securities the subject of an invitation for subscription or purchase, nor will they circulate or distribute the Information Memorandum or any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the leveraged index-linked securities, whether directly or indirectly, to persons in Singapore other than:

(a) an institutional investor (as defined in section 4A of the Securities and Futures Act (Chapter 289 of Singapore (the “SFA”));

(b) an accredited investor (as defined in section 4A of the SFA), and in accordance with the conditions, specified in Section 275 of the SFA;

(c) a person who acquires the leveraged index-linked securities for an aggregate consideration of not less than Singapore dollars Two Hundred Thousand (S$200,000) (or its equivalent in a foreign currency) for each transaction, whether such amount is paid for in cash, by exchange of shares or other assets, unless otherwise permitted by law; or

(d) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA.

ANNEX A

UNDERLYING INDICES AND UNDERLYING INDEX PUBLISHERS INFORMATION

We have derived all information contained in this prospectus supplement and the applicable pricing supplement regarding any specified underlying index or basket index, including, without limitation, its make up, its method of calculation and changes in its components and its historical closing values, from publicly available information. Such information reflects the policies of, and is subject to change by, the publisher of the applicable underlying index or basket index, whom we refer to as the underlying index publisher. Each underlying index or basket index is developed, calculated and maintained by its respective underlying index publisher. Neither we nor the agent has participated in the preparation of such documents or made any due diligence inquiry with respect to any underlying index or basket index or underlying index publisher in connection with the offering of the leveraged index-linked securities. In connection with the offering of leveraged index-linked securities, neither we nor the agent makes any representation that such publicly available information regarding any underlying index or basket index or underlying index publisher is accurate or complete. Furthermore, we cannot give any assurance that all events occurring prior to the date of any offering of leveraged index-linked securities (including events that would affect the accuracy or completeness of the publicly available information described in this paragraph or in the applicable pricing supplement) that would affect the value of any underlying index or basket index have been publicly disclosed. Subsequent disclosure of any such events could affect the value received at maturity or on any call date with respect to the leveraged index-linked securities and therefore the trading prices of the leveraged index-linked securities.

We or our affiliates may presently or from time to time engage in business with one or more of the issuers of the component stocks of any underlying index or basket index without regard to your interests, including extending loans to or entering into loans with, or making equity investments in, one or more of such issuers or providing advisory services to one or more of such issuers, such as merger and acquisition advisory services. In the course of our business, we or our affiliates may acquire non-public information about one or more of such issuers and neither we nor any of our affiliates undertakes to disclose any such information to you. In addition, we or our affiliates from time to time have published and in the future may publish research reports with respect to such issuers. These research reports may or may not recommend that investors buy or hold the securities of such issuers. As a prospective purchaser of leveraged index-linked securities, you should undertake an independent investigation of the issuers of the component stocks of the underlying index or basket indices and of the underlying index or basket indices to the extent required, in your judgment, to allow you to make an informed decision with respect to an investment in any leveraged index-linked securities.

In this prospectus supplement and any applicable pricing supplement, unless the context requires otherwise, references to any specific underlying index or basket index listed below will include any successor index to such underlying index or basket index and references to the underlying index publisher will include any successor thereto.

Dow Jones Euro STOXX 50® Index

The Dow Jones EURO STOXX 50® Index, which we refer to as the Euro STOXX 50 Index, was created by STOXX® Limited, a joint venture between Deutsche Boerse AG, Dow Jones & Company, Inc. and SWX Swiss Exchange. Publication of the Euro STOXX 50 Index began on February 28, 1998, based on an initial index value of 1,000 at December 31, 1991. The Euro STOXX 50 Index is published in The Wall Street Journal and disseminated on the STOXX Limited website: http://www.stoxx.com. Morgan Stanley obtained all information contained in this prospectus supplement regarding the Euro STOXX 50 Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, STOXX Limited. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the Euro STOXX 50 Index. STOXX Limited is under no obligation to continue to publish the Euro STOXX 50 Index and may discontinue publication of the Euro STOXX 50 Index at any time.

Euro STOXX 50 Index Composition and Maintenance. The Euro STOXX 50 Index is composed of 50 component stocks of market sector leaders from within the Dow Jones STOXX 600 Supersector Indices, which includes stocks selected from the Eurozone. The component stocks have a high degree of liquidity and represent the largest companies across all market sectors.

A-1

The composition of the Euro STOXX 50 Index is reviewed annually, based on the closing stock data on the last trading day in August. The component stocks are announced the first trading in September. Changes to the component stocks are implemented on the third Friday in September and are effective the following trading day. Changes in the composition of the Euro STOXX 50 Index are made to ensure that the Euro STOXX 50 Index includes the 50 market sector leaders from within the Euro STOXX Index.

The free float factors for each component stock used to calculate the Euro STOXX 50 Index, as described below, are reviewed, calculated and implemented on a quarterly basis and are fixed until the next quarterly review. Each component’s weight is capped at 10% of the index’s total free float market capitalization.

The Euro STOXX 50 Index is also reviewed on an ongoing basis. Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings and bankruptcy) that affect the Euro STOXX 50 Index composition are immediately reviewed. Any changes are announced, implemented and effective in line with the type of corporate action and the magnitude of the effect.

Euro STOXX 50 Index Calculation. The Euro STOXX 50 Index is calculated with the “Laspeyres formula,” which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the Euro STOXX 50 Index value can be expressed as follows:

The “free float market capitalization of the Euro STOXX 50 Index” is equal to the sum of the products of the closing price, market capitalization and free float factor for each component stock as of the time the Euro STOXX 50 Index is being calculated.

The divisor for the Euro STOXX 50 Index is adjusted to maintain the continuity of the Euro STOXX 50 Index values across changes due to corporate actions. The following is a summary of the adjustments to any component stock made for corporate actions and the effect of such adjustment on the divisor, where shareholders of the component stock will receive “B” number of shares for every “A” share held (where applicable).

| (1) | Cash dividend:
|  | Adjusted price = closing price – announced dividend * (1 – withholding tax)
|  | Divisor: decreases
| (2) | Special cash dividend:
|  | Adjusted price = closing price – announced dividend * (1 – withholding tax)
|  | Divisor: decreases
| (3) | Split and reverse split:
|  | Adjusted price = closing price * A/B
|  | New number of shares = old number of shares * B / A
|  | Divisor: no change

A-2

| (4) | Rights offering:
|  | Adjusted price = (closing price * A + subscription price * B) / (A + B)
|  | New number of shares = old number of shares * (A + B) / A
|  | Divisor: increases
| (5) | Stock dividend:
|  | Adjusted price = closing price * A / (A + B)
|  | New number of shares = old number of shares * (A + B) / A
|  | Divisor: no change
| (6) | Stock dividend of another company:
|  | Adjusted price = (closing price * A - price of other company * B) / A
|  | Divisor: decreases
| (7) | Return of capital and share consideration:
|  | Adjusted price = (closing price - dividend announced by company * (1-withholding tax)) * A / B
|  | New number of shares = old number of shares * B / A
|  | Divisor: decreases
| (8) | Repurchase shares / self tender:

|  | Adjusted price = | ((price before tender * old number of shares ) - (tender price * number
|  |  | of tendered shares)) / (old number of shares - number of tendered
|  |  | shares)

|  | New number of shares = old number of shares - number of tendered shares
|  | Divisor: decreases
| (9) | Spin-off:
|  | Adjusted price = (closing price * A - price of spun-off shares * B) / A
|  | Divisor: decreases
| (10) | Combination stock distribution (dividend or split) and rights offering:
|  | For this corporate action, the following additional assumptions apply:
|  | Shareholders receive B new shares from the distribution and C new shares from the
|  | rights offering for every A shares held
|  | If A is not equal to one share, all the following “new number of shares” formulae
|  | need to be divided by A:
|  | - If rights are applicable after stock distribution (one action applicable to other):
|  | Adjusted price = (closing price * A + subscription price * C * (1 + B / A)) / ((A + B) * (1 + C / A))
|  | New number of shares = old number of shares * ((A + B) * (1 + C / A)) / A

A-3

|  | Divisor: increases
|  | - If stock distribution is applicable after rights (one action applicable to other):
|  | Adjusted price = (closing price * A + subscription price * C) / ((A + C) * (1 + B / A))
|  | New number of shares = old number of shares * ((A + C) * (1 + B / A))
|  | Divisor: increases
|  | - Stock distribution and rights (neither action is applicable to the other):
|  | Adjusted price = (closing price * A + subscription price * C) / (A + B + C)
|  | New number of shares = old number of shares * (A + B +C) / A
|  | Divisor: increases

Dow Jones Industrial Average SM

The Dow Jones Industrial AverageSM, which we refer to as the DJIASM, is a price-weighted index composed of 30 common stocks selected at the discretion of the editors of The Wall Street Journal (the “WSJ”), which is published by Dow JonesSM & Company, Inc., which we refer to as Dow Jones, as representative of the broad market of U.S. industry. Morgan Stanley obtained all information contained in this prospectus supplement regarding the DJIA, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, Dow Jones. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the DJIA. Dow Jones is under no obligation to continue to publish the DJIA and may discontinue publication of the DJIA at any time.

There are no pre-determined criteria for selection of a component stock except that component companies represented by the DJIA should be established U.S. companies that are leaders in their industries. The DJIA serves as a measure of the entire U.S. market such as financial services, technology, retail, entertainment and consumer goods and is not limited to traditionally defined industrial stocks. Changes in the composition of the DJIA are made entirely by the editors of the WSJ without consultation with the component companies represented in the DJIA, any stock exchange, any official agency or us. In order to maintain continuity, changes to the component stocks included in the DJIA tend to be made infrequently and generally occur only after corporate acquisitions or other dramatic shifts in a component company’s core business. When one component stock is replaced, the entire index is reviewed. As a result, multiple component changes are often implemented simultaneously. The component stocks of the DJIA may be changed at any time for any reason.

The DJIA is price weighted rather than market capitalization weighted. Therefore, the component stock weightings are affected only by changes in the stocks’ prices, in contrast with the weightings of other indices that are affected by both price changes and changes in the number of shares outstanding. The value of the DJIA is the sum of the primary exchange prices of each of the 30 common stocks included in the DJIA, divided by a divisor. The divisor is changed in accordance with a mathematical formula to adjust for stock dividends, stock splits and other corporate actions. The current divisor of the DJIA is published daily in the WSJ and other publications. While this methodology reflects current practice in calculating the DJIA, no assurance can be given that Dow Jones will not modify or change this methodology in a manner that may affect the return on your investment.

The formula used to calculate divisor adjustments is:

FTSE TM 100 Index

The FTSETM 100 Index is calculated, published and disseminated by FTSE International Limited (“FTSE”), a company owned equally by the London Stock Exchange Plc (the “LSE”) and the Financial Times Limited (the “FT”), in association with the Institute and the Faculty of Actuaries. Morgan Stanley obtained all information contained in this prospectus supplement regarding the FTSE 100 Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, FTSE. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the FTSE 100 Index. FTSE is under no obligation to continue to publish the FTSE 100 Index and may discontinue publication of the FTSE 100 Index at any time.

The FTSE 100 Index was first calculated on January 3, 1984 with an initial base level index value of 1,000 points. Publication of the FTSE 100 Index began in February 1984. Real-time FTSE indices are calculated on systems managed by Reuters. Prices and FX rates used are supplied by Reuters.

The FTSE 100 Index is a free float adjusted index which measures the composite price performance of stocks of the largest 100 companies (determined on the basis of market capitalization) traded on the LSE. The 100 stocks included in the FTSE 100 Index (the “FTSE Underlying Stocks”) are selected from a reference group of stocks trading on the LSE which are in turn selected by excluding certain stocks that have low liquidity based on public float, accuracy and reliability of prices, size and number of trading days. The FTSE Underlying Stocks are selected from this reference group by selecting 100 stocks with the largest market value.

FTSE, the publisher of the FTSE 100 Index, is responsible for calculating, publishing and disseminating the FTSE 100 Index. The FTSE 100 Index is overseen by the FTSE’s Europe/Middle East/Africa Committee (the “FTSE EMEA Committee”), which is made up of independent senior industry representatives, which is responsible for the index review process.

FTSE can add, delete or substitute the stocks underlying the FTSE 100 Index or make other methodological changes that could change the value of the FTSE 100 Index. FTSE may discontinue or suspend calculation or

A-6

dissemination of the FTSE 100 Index. The FTSE EMEA Committee reviews the FTSE Underlying Stocks quarterly in March, June, September and December in order to maintain continuity in the index level. FTSE prepares information regarding possible companies to be included or excluded from the FTSE 100 Index using the close of business figures from the Tuesday before a review. The review is then presented to the FTSE EMEA Committee for approval.

Changes to the constituents can be prompted by new listings on the exchange, corporate actions (e.g., mergers and acquisitions) or an increase or decrease in a market capitalization. The FTSE Underlying Stocks may be replaced, if necessary, in accordance with deletion/addition rules which provide generally for the removal and replacement of a stock from the FTSE 100 Index if such stock is delisted or its issuer is subject to a takeover offer that has been declared unconditional or it has ceased, in the opinion of the FTSE EMEA Committee, to be a viable component of the FTSE 100 Index. To maintain continuity, a stock will be added at the quarterly review if it has risen to 90th place or above and a stock will be deleted if at the quarterly review it has fallen to 111th place or below, in each case ranked on the basis of market capitalization. Where a greater number of companies qualify to be inserted in the FTSE 100 Index than those qualifying to be deleted, the lowest ranking constituents presently included in the FTSE 100 Index will be deleted to ensure that an equal number of companies are inserted and deleted at the periodic review. Likewise, where a greater number of companies qualify to be deleted than those qualifying to be inserted, the securities of the highest ranking companies which are presently not included in the index will be inserted to match the number of companies being deleted at the periodic review.

The FTSE 100 Index is obtained by: (i) calculating the sum of the products of the per share price of each stock included in the FTSE 100 Index by the number of their respective outstanding shares (such sum, the “FTSE Aggregate Market Value”) as of the relevant current date and (ii) dividing the FTSE Aggregate Market Value as of the relevant current date by a divisor which represents the adjustments to the FTSE Aggregate Market Value as of the base date. The divisor is continuously adjusted to reflect changes, without distorting the FTSE 100 Index, in the issued share capital of individual underlying stocks, including the deletion and addition of stocks, the substitution of stocks, stock dividends and stock splits.

All rights to the FTSE 100 Index are owned by the FTSE, the publisher of the FTSE 100 Index. Morgan Stanley, the Calculation Agent and the Trustee disclaim all responsibility for the calculation or other maintenance of or any adjustments to the FTSE 100 Index. In addition, none of the LSE, the Financial Times and FTSE has any relationship to Morgan Stanley or the leveraged index-linked securities. None of the LSE, the Financial Times and the FTSE sponsors, endorses, authorizes, sells or promotes the leveraged index-linked securities, or has any obligation or liability in connection with the administration, marketing or trading of the leveraged index-linked securities or with the calculation of the payment at maturity.

License Agreement between FTSE International Limited and Morgan Stanley. The license agreement between FTSE International Limited and Morgan Stanley provides that the following language must be set forth in this prospectus supplement:

Hang Seng® Index

The Hang Seng® Index is compiled, published and managed by HSI Services Limited, a wholly owned subsidiary of the Hang Seng Bank, and was first calculated and published on November 24, 1969. The HSI is a market capitalization weighted stock market index in the Stock Exchange of Hong Kong Ltd. (the “SEHK”) and purports to be an indicator of the performance of the Hong Kong stock market. Morgan Stanley has derived all information contained in this prospectus supplement regarding the Hang Seng Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by HSI Services Limited. The Hang Seng Index was developed by HSI Services Limited and is calculated, maintained and published by HSI Services Limited. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of such information.

Only companies with a primary listing on the main board of the SEHK are eligible as constituents of the Hang Seng Index. Mainland China enterprises that have an H-share listing in Hong Kong are eligible for inclusion in the Hang Seng Index when they meet any one of the following conditions: (1) the H-share company has 100% of its ordinary share capital in the form of H-shares which are listed on the SEHK; (2) the H-share company has completed the process of share reform, with the result that there is no unlisted share capital in the company; or (3) for new H-share initial public offerings, the company has no unlisted share capital. For any H-share company included in the Hang Seng Index, only the H-share portion of the share capital of the company will be used for index calculation, subject to free float adjustment. H-shares are shares of mainland China companies listed on SEHK.

To be eligible for selection in the Hang Seng Index, a company: (1) must be among those that constitute the top 90% of the total market value of all primary shares listed on the SEHK (market value is expressed as an average of the past 12 months); (2) must be among those that constitute the top 90% of the total turnover of all primary listed shares on the SEHK (turnover is aggregated and individually assessed for eight quarterly sub-periods for the past 24 months); and (3) should normally have a listing history of 24 months. From the candidates, final selections are based on the following: (1) the market value and turnover rankings of the companies; (2) the representation of the sub-sectors within the Hang Seng Index directly reflecting that of the market; and (3) the financial performance of the companies.

Calculation Methodology. From September 11, 2006, and phased in over a period of 12 months from September 2006 to September 2007, the calculation methodology of the Hang Seng Index has been changed from a full market capitalization weighting to a free float-adjusted market capitalization weighting. Under this calculation methodology, the following shareholdings are viewed as strategic in nature and excluded for calculation: shares held by strategic shareholders who individually or collectively control more than 30% of the shareholdings; shares held by directors who individually control more than 5% of the shareholdings; shares held by a Hong Kong-listed company which controls more than 5% of the shareholdings as investments; and shares held by a shareholders who individually or collectively represent more than 5% of the shareholdings in the company and with a publicly disclosed lock-up management. A free float adjustment factor representing the proportion of shares that is free floated as a percentage of the issued shares, is rounded up to the nearest multiple of 5% for the calculation of the Hang Seng Index and is updated half-yearly.

A cap of 15% on individual stock weightings is applied. A cap factor is calculated half-yearly to coincide with the regular update of the free float adjustment factor. Additional re-capping is performed upon constituent changes.

KOSPI 200 Index

Unless otherwise stated, all information regarding the KOSPI 200 Index is derived from the Korea Stock Exchange (“KSE”) or other publicly available sources. Such information reflects the policies of KSE as stated in such sources, and such policies are subject to change by KSE. Morgan Stanley does not assume any responsibility for the accuracy or completeness of such information. KSE is under no obligation to continue to publish the KOSPI 200 Index and may discontinue publication of the KOSPI 200 Index at any time.

The KOSPI 200 Index is a market capitalization based index and was developed as an underlying index for derivatives products (index futures and index options) traded on the KRX-Futures Market. The calculation of the value of the KOSPI 200 Index (discussed below in further detail) is based on the relative value of the aggregated current Market Value (as defined below) of the common stocks of 200 companies (the “Constituent Stocks”) as of a particular time as compared to the aggregated average Market Value of the common stocks of 200 companies at the base date of January 3, 1990. The current “Market Value” of any Constituent Stock is the product of the market price per share and the number of the then outstanding shares of such Constituent Stock. KSE chooses companies for inclusion in the KOSPI 200 Index with an aim of accurately representing overall market movement. KSE may from time to time, in its sole discretion, add companies to, or delete companies from, the KOSPI 200 Index to achieve the objectives stated above. The KOSPI 200 Index selects stocks of companies that belong to one of eight industry groups, whose market capitalization is at least 1% of the total market capitalization. The capitalization requirement ensures the high percentage of market capitalization of Constituent Stocks against the total. Stocks initially listed or relisted after May 1 of the year preceding the year of the periodic realignment review date, stocks designated as administrative issue as of the periodic realignment review date, stocks of securities investment companies, issues of liquidation sale and stocks deemed unsuitable are ineligible to become a Constituent Stock of the KOSPI 200 Index.

Basic selection criteria are the average market capitalization obtained by dividing the aggregated value (attained by multiplying the closing price of the listed common shares by the number of listed common shares for one year from April of the year preceding the year to which the periodic realignment review date belongs), by 12, and the sum of daily trading value for the same period. In the case of a stock which has been reclassified under a different industry group, such stock is grouped with the newly classified industry group.

A-9

First, the Constituent Stocks from non-manufacturing industries are chosen on the basis of rank order of average monthly market capitalization, while ensuring that the accumulated market capitalization of a stock is at least 70% of the total market capitalization of the same industry group. The number of stocks selected is considered as is the number of Constituent Stocks chosen from the same industry group. However, a stock is excluded if its ranking of annual trading value is below 85% of the same industry group, and a stock that satisfies the trading value requirement is chosen from among the stocks whose market capitalization is ranked next.

Second, the Constituent Stocks from the manufacturing industry are selected by rank order of market capitalization, while ensuring that annual trading value of stocks are ranked above 85% of the industry group. The number of the stocks selected from the manufacturing industry is the number obtained by subtracting the number of Constituent Stocks chosen from the non-manufacturing industry group from 200.

Notwithstanding the above criteria, a stock whose market capitalization is within the top 50 of its industry group may be included in the constituents. The KOSPI Maintenance Committee (the “KOSPI Committee”) makes the decision while taking into account such factors as the percentage of market capitalization of the industry group to the total and the liquidity of such stock.

To ensure that the KOSPI 200 Index accurately represents the overall market movement, its Constituent Stocks are realigned as the need arises. There are two types of realignments: periodic realignment and special realignment. Periodic realignment takes place regularly once a year, on the trading day following the day which is the last trading day of June contracts of both the index futures and index options. Special realignment takes place at the time when a stock has to be excluded from the constituents as a result of, for instance, delisting, designation as administrative issue or a merger.

The method of periodic realignment is similar to the method used for selection of Constituent Stocks. However, to maintain constancy of the KOSPI 200 Index, a replacement stock must both satisfy the criteria for selection of Constituent Stocks, and its ranking of market capitalization should be within 90% of total market capitalization of the constituents of the same industry group. However, even if an existing Constituent Stock does not satisfy the criteria for selection of Constituent Stocks, such stock remains a constituent as long as its ranking of market capitalization is within 110% of the market capitalization of the constituents. In the case of a stock with a market capitalization ranking that has reached 90% of the total market capitalization of the constituents of the same industry group, such stock is excluded unless there is an existing Constituent Stock whose ranking falls below 110% of the constituents.

Special realignment is carried out by choosing a stock from a replacement list prepared beforehand in a priority order by industry group. In the event that the replacement list includes no stock for a specific industry, a stock is chosen from the manufacturing industry group.

In cases where there is an initial listing of a stock that is deemed to have high liquidity and is worthy in terms of its impact on KOSPI 200 Index, a Constituent Stock is merged into non-Constituent Stock or a company is established as result of merger between the constituent, it is possible to include before the periodic realignment date.

The level of the KOSPI 200 Index reflects the total current Market Value of all 200 Constituent Stocks relative to the base index of the KOSPI 200 Index as of the base date of January 3, 1990 (the “Base Index.”), which is 100. An indexed number is used to represent the results of this calculation.

The actual aggregate Market Value of the Constituent Stocks at the base date (the “KOSPI 200 Base Market Value”) has been set. In practice, the calculation of the KOSPI 200 Index is computed by dividing the total current aggregated Market Value of the Constituent Stocks by the KOSPI 200 Base Market Value and then multiplying by the Base Index of 100.

In order to maintain the consistency of the KOSPI 200 Index, the Market Value and KOSPI 200 Base Market Value can be readjusted. Readjustment includes changing the KOSPI 200 Base Market Value when there is an event, such as a distribution of rights or dividends, that affects the stock price, in order to equalize the stock price index on the day before the event and the stock price index on the day of the event. The following formula is used:

A-10

Current Market Value increases or decreases when there is a rights offering a new listing, a delisting or merger. Therefore, to maintain consistency, the KOSPI 200 Base Market Value is adjusted when there is a change in current Market Value, using the following formula:

The KOSPI Committee is charged with reviewing matters relating to calculation and management of the KOSPI 200 Index. The KOSPI Committee is composed of 10 members who are chosen as representatives of institutional investors and securities related institutions, legal and accounting professions, and professors and researchers. The KOSPI Committee is responsible for matters relating to the calculation method of the KOSPI 200 Index; matters relating to selection and realignment of KOSPI 200 Constituent Stocks; matters relating to establishment, amendment and abolishment of the criteria for selection of KOSPI 200 Constituent Stocks; and any other matters that are requested by the chief executive officer of the KSE.

Regular meetings of the KOSPI Committee are held in May of each year for the purpose of realigning the Constituent Stocks, but a special meeting can be called if need arises.

Although KSE currently employs the above methodology to calculate the KOSPI 200 Index, we cannot assure you that KSE will not modify or change this methodology in a manner that may affect the return on your investment.

MSCI EAFE Index®

The MSCI EAFE Index® is a stock index calculated, published and disseminated daily by MSCI, a majority-owned subsidiary of Morgan Stanley, through numerous data vendors, on the MSCI website and in real time on Bloomberg Financial Markets and Reuters Limited. See “—Affiliation of MSCI, MS & Co. and Morgan Stanley” below.

Morgan Stanley obtained all information contained in this prospectus supplement regarding the MSCI EAFE Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, MSCI. Neither MSCI nor Morgan Stanley has any obligation to continue to calculate and publish, and may discontinue calculation and publication of the MSCI EAFE Index.

The MSCI EAFE Index is intended to provide performance benchmarks for the developed equity markets in Australia and New Zealand and in Europe and Asia, which are Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy, Japan, the Netherlands, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom.

A-11

Index Calculation. The performance of the MSCI EAFE Index is a free float weighted average of the U.S. dollar values of all of the equity securities (the “Component Securities”) constituting the MSCI indexes for the 21 selected countries (the “Component Country Indices”). Each Component Country Index is a sampling of equity securities across industry groups in such country’s equity markets. See “—Maintenance of the MSCI EAFE Index and the Component Country Indices” below.

Prices used to calculate the Component Securities are the official exchange closing prices or prices accepted as such in the relevant market. In general, all prices are taken from the main stock exchange in each market. Closing prices are converted into U.S. dollars using the closing exchange rates calculated by The WM Company at 5 p.m. Central Europe Time. The U.S. dollar value of the MSCI EAFE Index is calculated based on the free float-adjusted market capitalization in U.S. dollars of the Component Securities. The MSCI EAFE Index was launched on December 31, 1969 at an initial value of 100.

Maintenance of the MSCI EAFE Index and the Component Country Indices. In order to maintain the representativeness of the MSCI EAFE Index, structural changes to the MSCI EAFE Index as a whole may be made by adding or deleting Component Country Indices and the related Component Securities. Currently, such changes in the MSCI EAFE Index may only be made on four dates throughout the year: after the last scheduled index close of each February, May, August and November.

MSCI may add additional Component Country Indices to the MSCI EAFE Index or subtract one or more of its current Component Country Indices prior to the expiration of the leveraged index-linked securities. Any such adjustments are made to the MSCI EAFE Index so that the value of the MSCI EAFE Index at the effective date of such change is the same as it was immediately prior to such change.

Each Component Country Index is maintained with the objective of reflecting, on a timely basis, the evolution of the underlying equity markets. In maintaining each Component Country Index, emphasis is also placed on its continuity, replicability and on minimizing turnover in the MSCI EAFE Index.

MSCI classifies index maintenance in three broad categories. The first consists of ongoing event-related changes, such as mergers and acquisitions, which are generally implemented in the indices in which they occur. The second category consists of quarterly index reviews, aimed at promptly reflecting other significant market events. The third category consists of full Component Country Index reviews that systematically re-assess the various dimensions of the equity universe for all countries simultaneously and are conducted on a fixed annual timetable.

Ongoing event-related changes to the indices are the result of mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events. They can also result from capital reorganizations in the form of rights issues, bonus issues, public placements and other similar corporate actions that take place on a continuing basis. These changes are reflected in the indices at the time of the event. All changes resulting from corporate events are announced prior to their implementation, provided all necessary information on the event is available.

The quarterly index review process is designed to ensure that the indices continue to be an accurate reflection of evolving equity markets. This goal is achieved by rapidly reflecting significant market driven changes that were not captured in the MSCI EAFE Index at the time of their actual occurrence and that should not wait until the annual full Component Country Index review due to their importance. These quarterly index reviews may result in additions and deletions of Component Securities from a Component Country Index and changes in “foreign inclusion factors” and in number of shares. Additions and deletions to Component Securities may result from: the addition or deletion of securities due to the significant over- or under-representation of one or more industry groups as a result of mergers, acquisitions, restructurings or other major market events affecting the industry group; the addition or deletion of securities resulting from changes in industry classification, significant increases or decreases in free float or relaxation/removal or decreases of foreign ownership limits not implemented immediately; the additions of large companies that did not meet the minimum size criterion for inclusion at the time of their initial public offering or secondary offering; the replacement of companies which are no longer suitable industry representatives; the deletion of securities whose overall free float has fallen to less than 15% and that do not meet specified criteria; the deletion of securities that have become very small or illiquid; the replacement of securities resulting from the review of price source for Component Securities with both domestic and foreign board quotations; and the addition or deletion of securities as a result of other market events. Significant changes in free float estimates and corresponding changes

A-12

in the foreign inclusion factor for Component Securities may result from: large market transactions involving strategic shareholders that are publicly announced; secondary offerings that, given lack of sufficient notice, were not reflected immediately; increases in foreign ownership limits; decreases in foreign ownership limits not applied earlier; corrections resulting from the reclassification of shareholders from strategic to non-strategic, and vice versa; updates to foreign inclusion factors following the public disclosure of new shareholder structures for companies involved in mergers, acquisitions or spin-offs, where different from MSCI’s pro forma free float estimate at the time of the event; large conversions of exchangeable bonds and other similar securities into already existing shares; the end of lock-up periods or expiration of loyalty incentives for non-strategic shareholders; and changes in the foreign inclusion factor as a result of other events of similar nature. Changes in the number of shares are generally small and result from, for example, exercise of options or warrants, conversion of convertible bonds or other instruments or share buybacks. The implementation of changes resulting from quarterly index reviews occurs on only three dates throughout the year: as of the close of the last business day of February, August and November. The results of the quarterly index reviews are announced at least two weeks prior to their implementation. Any country may be impacted at the quarterly index review.

The annual full Component Country Index review includes a re-appraisal of the free float-adjusted industry group representation within a country relative to the 85% target, a detailed review of the shareholder information used to estimate free float for Component and non-Component Securities, updating the minimum size guidelines for new and existing Component Securities, as well as changes typically considered for quarterly index reviews. During a full Component Country Index review, securities may be added or deleted from a Component Country Index for a range of reasons, including the reasons discussed in the preceding sentence and the reasons for Component Securities changes during quarterly index reviews as discussed above. The results of the annual full Component Country Index reviews are announced at least two weeks in advance of their effective implementation date as of the close of the last business day in May.

Index maintenance also includes monitoring and completing the adjustments for share changes, stock splits, stock dividends, and stock price adjustments due to company restructurings or spinoffs. Index maintenance of the Component Country Indices is reflected in the MSCI EAFE Index.

Selection of Component Securities and Calculating and Adjusting for Free Float. The selection of the Component Securities for each Component Country Index is based on the following guidelines:

| (i) | Define the universe of listed securities within each country;
| (ii) | Adjust the total market capitalization for each security for its respective free float available to foreign investors;
| (iii) | Classify securities into industry groups under the Global Industry Classification Standard (GICS); and
| (iv) | Select securities for inclusion according to MSCI’s index construction rules and guidelines.

To determine the free float of a security, MSCI considers the proportion of shares of such security available for purchase in the public equity markets by international investors. In practice, limitations on the investment opportunities for international investors include: strategic stakes in a company held by private or public shareholders whose investment objective indicates that the shares held are not likely to be available in the market; limits on the proportion of a security’s share capital authorized for purchase by non-domestic investors; or other foreign investment restrictions which materially limit the ability of foreign investors to freely invest in a particular equity market, sector or security.

MSCI will then derive a “foreign inclusion factor” for the company that reflects the percentage of the total number of shares of the company that are not subject to strategic shareholdings and/or foreign shareholder ownership or investment limits. MSCI will then “float-adjust” the weight of each constituent company in an index by the company’s foreign inclusion factor. Typically, securities with a free float adjustment ratio of .15 or less will not be eligible for inclusion in MSCI’s indices.

A-13

Once the free float factor has been determined for a security, the security’s total market capitalization is then adjusted by such free float factor, resulting in the free float-adjusted market capitalization figure for the security.

These guidelines and the policies implementing the guidelines are the responsibility of, and, ultimately, subject to adjustment by, MSCI.

The MSCI EAFE Index is Subject to Currency Exchange Risk. Because the closing prices of the Component Securities are converted into U.S. dollars for purposes of calculating the value of the MSCI EAFE Index, investors in the leveraged index-linked securities will be exposed to currency exchange rate risk with respect to each of the currencies in which the Component Securities trade. Exposure to currency changes will depend on the extent to which such currencies strengthen or weaken against the U.S. dollar and the relative weight of the Component Securities in the MSCI EAFE Index denominated in each such currency. The devaluation of the U.S. dollar against the currencies in which the Component Securities trade will result in an increase in the value of the MSCI EAFE Index. Conversely, if the U.S. dollar strengthens against such currencies, the value of the MSCI EAFE Index will be adversely affected and may reduce or eliminate any return on your investment. Fluctuations in currency exchange rates can have a continuing impact on the value of the MSCI EAFE Index, and any negative currency impact on the MSCI EAFE Index may significantly decrease the value of the leveraged index-linked securities. The return on an index composed of the Component Securities where the closing price is not converted into U.S. dollars can be significantly different than the return on the MSCI EAFE Index, which is converted into U.S. dollars.

MSCI Taiwan Index SM

The MSCI Taiwan IndexSM is a stock index owned, calculated, and published by MSCI, a majority-owned subsidiary of Morgan Stanley. See “—Affiliation of MSCI, MS & Co. and Morgan Stanley” below.

Morgan Stanley obtained all information contained in this prospectus supplement regarding the MSCI Taiwan Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, MSCI. Neither MSCI nor Morgan Stanley has any obligation to continue to calculate and publish, and may discontinue calculation and publication of the MSCI Taiwan Index.

The MSCI Taiwan Index is a free float adjusted market capitalization index of securities listed on the Taiwan Stock Exchange. MSCI targets an 85% free float adjusted market representation level within each industry group in Taiwan.

Selection Criteria. The security selection process within each industry group is based on analysis of the following: i) Each company’s business activities and the diversification that its securities would bring to the index. ii) All other things being equal, MSCI targets for inclusion the most sizable securities in an industry group. Securities that do not meet the minimum size guidelines are not considered for inclusion. iii) MSCI targets for inclusion the most liquid securities in an industry group. MSCI does not define absolute minimum or maximum liquidity levels for stock inclusion or exclusion from the MSCI Taiwan Index but considers each stock’s relative standing within Taiwan and between cycles. Only securities of companies with an estimated overall or security free float greater than 15% are generally considered for inclusion in the MSCI Taiwan Index. For more information on the selection criteria, see the discussion regarding the Component Country Indices in “—MSCI EAFE Index—Selection of Component Securities and Calculating and Adjusting for Free Float,” which apply to the MSCI Taiwan Index as well as the Component Country Indices of the MSCI EAFE Index.

Index Calculation. The MSCI Taiwan Index is computed generally by multiplying the previous day’s index level by the free float adjusted market capitalization level of each share in the MSCI Taiwan Index on the prior day divided by the free float market capitalization level of each share in the MSCI Index on the current day. The numerator is adjusted market capitalization, but the denominator is unadjusted, meaning that the price adjustment factor is applied to the numerator, but not the denominator.

Maintenance of the MSCI Taiwan Index. There are three broad categories of MSCI Taiwan Index maintenance: an annual full country index review that reassesses the various dimensions of the equity universe in Taiwan; quarterly index reviews, aimed at promptly reflecting other significant market events; and ongoing event-related changes, such as mergers and acquisitions, which are generally implemented in the index rapidly as they occur. For more information on the maintenance standards, see the discussion regarding the Component Country Indices in “—MSCI EAFE Index—Maintenance of the MSCI EAFE Index and the Component Country Indices,” which apply to the MSCI Taiwan Index as well as the Component Country Indices of the MSCI EAFE Index.

NASDAQ-100 Index®

The NASDAQ-100 Index® was developed by The Nasdaq Stock Market, Inc., which we refer to as The Nasdaq®. The NASDAQ-100 Index is determined and calculated by The Nasdaq and was first published in January 1985. Morgan Stanley obtained all information contained in this prospectus supplement regarding the NASDAQ-100 Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, The Nasdaq. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the NASDAQ-100 Index. The Nasdaq is under no obligation to continue to publish the NASDAQ-100 Index and may discontinue publication of the NASDAQ-100 Index at any time.

The NASDAQ-100 Index is a modified capitalization-weighted index of 100 of the largest non-financial companies listed on the The NASDAQ Stock Market LLC. The NASDAQ-100 Index constitutes a broadly diversified segment of the largest securities listed on The NASDAQ Stock Market LLC and includes companies across a variety of major industry groups. At any moment in time, the value of the NASDAQ-100 Index equals the aggregate value of the then-current NASDAQ-100 Index share weights of each of the NASDAQ-100 Index component securities, which are based on the total shares outstanding of each such NASDAQ-100 Index component security, multiplied by each such security’s respective last sale price on The NASDAQ Stock Market LLC (which may be the official closing price published by The NASDAQ Stock Market LLC), and divided by a scaling factor (the “divisor”), which becomes the basis for the reported NASDAQ-100 Index value. The divisor serves the

A-18

purpose of scaling such aggregate value (otherwise in the trillions) to a lower order of magnitude which is more desirable for NASDAQ-100 Index reporting purposes.

To be eligible for inclusion in the NASDAQ-100 Index, a security must be traded on the The NASDAQ Stock Market LLC and meet the other eligibility criteria, including the following: the security’s U.S. listing must be exclusively on the NASDAQ Global Select Market or the NASDAQ Global Market (unless the security was dually listed on another U.S. market prior to January 1, 2004 and has continuously maintained such listing), the security must be of a non-financial company; only one class of security per issuer is allowed; the security may not be issued by an issuer currently in bankruptcy proceedings; the security must have an average daily trading volume of at least 200,000 shares; the security must have “seasoned” on The NASDAQ Stock Market LLC or another recognized market (generally a company is considered to be seasoned by The Nasdaq if it has been listed on a market for at least two years; in the case of spin-offs, the operating history of the spin-off will be considered); if the security would otherwise qualify to be in the top 25% of the securities included in the NASDAQ-100 Index by market capitalization for the six prior consecutive month ends, then a one-year “seasoning” criteria would apply; if the security is of a foreign issuer, it must have listed options or be eligible for listed-options trading; the issuer of the security may not have annual financial statements with an audit opinion which the auditor or the company have indicated cannot be currently relied upon; and the issuer of the security may not have entered into a definitive agreement or other arrangement which would result in the security no longer being listed on The NASDAQ Stock Market LLC within the next six months.

In addition, to be eligible for continued inclusion in the NASDAQ-100 Index, the following criteria apply: the security’s U.S. listing must be exclusively on the NASDAQ Global Select Market or the NASDAQ Global Market (unless the security was dually listed on another U.S. market prior to January 1, 2004 and has continuously maintained such listing); the security must be of a non-financial company; the security may not be issued by an issuer currently in bankruptcy proceedings; the security must have an average daily trading volume of at least 200,000 shares; if the security is of a foreign issuer, it must have listed options or be eligible for listed-options trading; the issuer of the security may not have annual financial statements with an audit opinion which the auditor or the company have indicated cannot be currently relied upon; and the security must have an adjusted market capitalization equal to or exceeding 0.10% of the aggregate adjusted market capitalization of the NASDAQ-100 Index at each month end. In the event a company does not meet this criterion for two consecutive month ends, it will be removed from the NASDAQ-100 Index effective after the close of trading on the third Friday of the following month.

The securities in the NASDAQ-100 Index are monitored every day by The Nasdaq with respect to changes in total shares outstanding arising from secondary offerings, stock repurchases, conversions or other corporate actions. The Nasdaq has adopted the following quarterly scheduled weight adjustment procedures with respect to such changes. If the change in total shares outstanding arising from such corporate action is greater than or equal to 5.0%, such change is made to the NASDAQ-100 Index on the evening prior to the effective date of such corporate action or as soon as practical thereafter. Otherwise, if the change in total shares outstanding is less than 5.0%, then all such changes are accumulated and made effective at one time on a quarterly basis after the close of trading on the third Friday in each of March, June, September and December. In either case, the NASDAQ-100 Index share weights for such NASDAQ-100 Index component securities are adjusted by the same percentage amount by which the total shares outstanding have changed in such NASDAQ-100 Index component securities.

Additionally, The Nasdaq may periodically (ordinarily, several times per quarter) replace one or more component securities in the NASDAQ-100 Index due to mergers, acquisitions, bankruptcies or other market conditions, or due to delisting if an issuer chooses to list its securities on another marketplace, or if the issuers of such component securities fail to meet the criteria for continued inclusion in the NASDAQ-100 Index.

The NASDAQ-100 Index share weights are also subject, in certain cases, to a rebalancing (see “Rebalancing of the NASDAQ-100 Index for Modified Capitalization-Weighted Methodology” below). Ordinarily, whenever there is a change in the NASDAQ-100 Index share weights or a change in a component security included in the NASDAQ-100 Index, The Nasdaq adjusts the divisor to assure that there is no discontinuity in the value of the NASDAQ-100 Index which might otherwise be caused by such change.

Annual Ranking Review. The NASDAQ-100 Index component securities are evaluated on an annual basis, except under extraordinary circumstances which may result in an interim evaluation, the “Annual Ranking Review,” as described below. Securities listed on The NASDAQ Stock Market LLC which meet the eligibility criteria described above are ranked by market value using closing prices as of the end of October and publicly available total shares outstanding as of the end of November. NASDAQ-100 Index-eligible securities which are already in the NASDAQ-100 Index and which are in the top 150 eligible securities (based on market value) are retained in the NASDAQ-100 Index provided that such security was ranked in the top 100 eligible securities as of the previous year’s ranking review. Securities not meeting such criteria are replaced. The replacement securities chosen are the largest market capitalization NASDAQ-100 Index-eligible securities not currently in the NASDAQ-100 Index. Generally, the list of annual additions and deletions is publicly announced via a press release in the early part of December. Replacements are made effective after the close of trading on the third Friday in December. Moreover, if at any time during the year a NASDAQ-100 Index component security is no longer traded on The Nasdaq, or is otherwise determined by The Nasdaq to become ineligible for continued inclusion in the NASDAQ-100 Index, the security will be replaced with the largest market capitalization security not currently in the NASDAQ-100 Index and meeting the NASDAQ-100 Index eligibility criteria listed above.

Rebalancing of the NASDAQ-100 Index for Modified Capitalization-weighted Methodology. Effective after the close of trading on December 18, 1998, the NASDAQ-100 Index has been calculated under a “modified capitalization-weighted” methodology, which is a hybrid between equal weighting and conventional capitalization weighting. This methodology is expected to: (1) retain in general the economic attributes of capitalization weighting; (2) promote portfolio weight diversification (thereby limiting domination of the NASDAQ-100 Index by a few large stocks); (3) reduce NASDAQ-100 Index performance distortion by preserving the capitalization ranking of companies; and (4) reduce market impact on the smallest NASDAQ-100 Index component securities from necessary weight rebalancings.

Under the methodology employed, on a quarterly basis coinciding with The Nasdaq’s quarterly scheduled weight adjustment procedures described above, the NASDAQ-100 Index component securities are categorized as either “Large Stocks” or “Small Stocks” depending on whether their current percentage weights (after taking into account such scheduled weight adjustments due to stock repurchases, secondary offerings or other corporate actions) are greater than, or less than or equal to, the average percentage weight in the NASDAQ-100 Index (i.e., as a 100-stock index, the average percentage weight in the NASDAQ-100 Index is 1.0%) .

Such quarterly examination will result in a NASDAQ-100 Index rebalancing if either one or both of the following two weight distribution requirements are not met: (1) the current weight of the single largest market capitalization NASDAQ-100 Index component security must be less than or equal to 24.0% and (2) the “collective weight” of those NASDAQ-100 Index component securities whose individual current weights are in excess of 4.5%, when added together, must be less than or equal to 48.0% . In addition, The Nasdaq may conduct a special rebalancing if it is determined necessary to maintain the integrity of the NASDAQ-100 Index.

If either one or both of these weight distribution requirements are not met upon quarterly review or The Nasdaq determines that a special rebalancing is required, a weight rebalancing will be performed in accordance with the following plan. First, relating to weight distribution requirement (1) above, if the current weight of the single largest NASDAQ-100 Index component security exceeds 24.0%, then the weights of all Large Stocks will be scaled down proportionately towards 1.0% by enough for the adjusted weight of the single largest NASDAQ-100 Index component security to be set to 20.0% . Second, relating to weight distribution requirement (2) above, for those NASDAQ-100 Index component securities whose individual current weights or adjusted weights in accordance with the preceding step are in excess of 4.5%, if their “collective weight” exceeds 48.0%, then the weights of all Large Stocks will be scaled down proportionately towards 1.0% by just enough for the “collective weight,” so adjusted, to be set to 40.0% .

The aggregate weight reduction among the Large Stocks resulting from either or both of the above rescalings will then be redistributed to the Small Stocks in the following iterative manner. In the first iteration, the weight of the largest Small Stock will be scaled upwards by a factor which sets it equal to the average NASDAQ-100 Index weight of 1.0% . The weights of each of the smaller remaining Small Stocks will be scaled up by the same factor reduced in relation to each stock’s relative ranking among the Small Stocks such that the smaller the NASDAQ-100

A-20

Index component security in the ranking, the less the scale-up of its weight. This is intended to reduce the market impact of the weight rebalancing on the smallest component securities in the NASDAQ-100 Index.

In the second iteration, the weight of the second largest Small Stock, already adjusted in the first iteration, will be scaled upwards by a factor which sets it equal to the average index weight of 1.0% . The weights of each of the smaller remaining Small Stocks will be scaled up by this same factor reduced in relation to each stock’s relative ranking among the Small Stocks such that, once again, the smaller the stock in the ranking, the less the scale-up of its weight.

Additional iterations will be performed until the accumulated increase in weight among the Small Stocks exactly equals the aggregate weight reduction among the Large Stocks from rebalancing in accordance with weight distribution requirement (1) and/or weight distribution requirement (2).

Then, to complete the rebalancing procedure, once the final percent weights of each NASDAQ-100 Index component security are set, the NASDAQ-100 Index share weights will be determined anew based upon the last sale prices and aggregate capitalization of the NASDAQ-100 Index at the close of trading on the Thursday in the week immediately preceding the week of the third Friday in March, June, September, and December. Changes to the NASDAQ-100 Index share weights will be made effective after the close of trading on the third Friday in March, June, September, and December and an adjustment to the NASDAQ-100 Index divisor will be made to ensure continuity of the NASDAQ-100 Index. Ordinarily, new rebalanced weights will be determined by applying the above procedures to the current NASDAQ-100 Index share weights. However, The Nasdaq may from time to time determine rebalanced weights, if necessary, by instead applying the above procedure to the actual current market capitalization of the NASDAQ-100 Index components. In such instances, The Nasdaq would announce the different basis for rebalancing prior to its implementation.

Nikkei 225 Index

The Nikkei 225 Index is a stock index calculated, published and disseminated by Nihon Keizai Shimbun, Inc., which we refer to as NIKKEI, that measures the composite price performance of selected Japanese stocks. Morgan Stanley obtained all information contained in this prospectus supplement regarding the Nikkei 225 Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, NIKKEI. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the Nikkei 225 Index. NIKKEI is under no obligation to continue to publish the Nikkei 225 Index and may discontinue publication of the Nikkei 225 Index at any time.

The Nikkei 225 Index currently is based on 225 underlying stocks (the “Nikkei Underlying Stocks”) trading on the Tokyo Stock Exchange (the “TSE”) representing a broad cross-section of Japanese industries. Stocks listed in the First Section of the TSE are among the most actively traded stocks on the TSE. All 225 Nikkei Underlying Stocks are stocks listed in the First Section of the TSE. NIKKEI rules require that the 75 most liquid issues (one-third of the component count of the Nikkei 225 Index) be included in the Nikkei 225 Index. NIKKEI first calculated and published the Nikkei 225 Index in 1970.

The 225 companies included in the Nikkei 225 Index are divided into six sector categories: Technology, Financials, Consumer Goods, Materials, Capital Goods/Others and Transportation and Utilities. These six sector categories are further divided into 36 industrial classifications as follows:

Technology — Pharmaceuticals, Electrical machinery, Automobiles, Precision machinery, Telecommunications

Financials — Banks, Miscellaneous finance, Securities, Insurance

Consumer Goods — Marine products, Food, Retail, Services

Materials — Mining, Textiles, Paper & pulp, Chemicals, Oil, Rubber, Ceramics, Steel, Nonferrous metals, Trading House

Capital Goods/Others — Construction, Machinery, Shipbuilding, Transportation equipment, Miscellaneous manufacturing, Real estate

Transportation and Utilities — Railroads & Buses, Trucking, Shipping, Airlines, Warehousing, Electric power, Gas

The Nikkei 225 Index is a modified, price-weighted index (i.e., a Nikkei Underlying Stock’s weight in the index is based on its price per share rather than the total market capitalization of the issuer) which is calculated by (i) multiplying the per share price of each Nikkei Underlying Stock by the corresponding weighting factor for such Nikkei Underlying Stock (a “Weight Factor”), (ii) calculating the sum of all these products and (iii) dividing such sum by a divisor (the “Nikkei Divisor”). The Nikkei Divisor was initially set at 225 for the date of May 16, 1949 using historical numbers from May 16, 1949, the date on which the Tokyo Stock Exchange was reopened. The Nikkei Divisor is subject to periodic adjustments as set forth below. Each Weight Factor is computed by dividing ¥50 by the par value of the relevant Nikkei Underlying Stock, so that the share price of each Nikkei Underlying Stock when multiplied by its Weight Factor corresponds to a share price based on a uniform par value of ¥50. The

A-22

stock prices used in the calculation of the Nikkei 225 Index are those reported by a primary market for the Nikkei Underlying Stocks (currently the TSE). The level of the Nikkei 225 Index is calculated once per minute during TSE trading hours.

In order to maintain continuity in the Nikkei 225 Index in the event of certain changes due to non-market factors affecting the Nikkei Underlying Stocks, such as the addition or deletion of stocks, substitution of stocks, stock splits or distributions of assets to stockholders, the Nikkei Divisor used in calculating the Nikkei 225 Index is adjusted in a manner designed to prevent any instantaneous change or discontinuity in the level of the Nikkei 225 Index. Thereafter, the Nikkei Divisor remains at the new value until a further adjustment is necessary as the result of another change. As a result of such change affecting any Nikkei Underlying Stock, the Nikkei Divisor is adjusted in such a way that the sum of all share prices immediately after such change multiplied by the applicable Weight Factor and divided by the new Nikkei Divisor (i.e., the level of the Nikkei 225 Index immediately after such change) will equal the level of the Nikkei 225 Index immediately prior to the change.

A Nikkei Underlying Stock may be deleted or added by NIKKEI. Any stock becoming ineligible for listing in the First Section of the TSE due to any of the following reasons will be deleted from the Nikkei Underlying Stocks: (i) bankruptcy of the issuer, (ii) merger of the issuer with, or acquisition of the issuer by, another company, (iii) delisting of such stock, (iv) transfer of such stock to the “Seiri-Post” because of excess debt of the issuer or because of any other reason or (v) transfer of such stock to the Second Section. In addition, a component stock transferred to the “Kanri-Post” (Posts for stocks under supervision) is in principle a candidate for deletion. Nikkei Underlying Stocks with relatively low liquidity, based on trading value and rate of price fluctuation over the past five years, may be deleted by NIKKEI. Upon deletion of a stock from the Nikkei Underlying Stocks, NIKKEI will select a replacement for such deleted Nikkei Underlying Stock in accordance with certain criteria. In an exceptional case, a newly listed stock in the First Section of the TSE that is recognized by NIKKEI to be representative of a market may be added to the Nikkei Underlying Stocks. In such a case, an existing Nikkei Underlying Stock with low trading volume and deemed not to be representative of a market will be deleted by NIKKEI.

A list of the issuers of the Nikkei Underlying Stocks constituting Nikkei 225 Index is available from the Nikkei Economic Electronic Databank System and from the Stock Market Indices Data Book published by NIKKEI. NIKKEI may delete, add or substitute any stock underlying the Nikkei 225 Index.

PHLX Housing Sector SM Index

The PHLX Housing SectorSM Index (the “PHLX Housing Index”) was developed by the Philadelphia Stock Exchange, Inc. (the “PHLX”) and is calculated, maintained and published by PHLX. Morgan Stanley obtained all information contained in this prospectus supplement regarding the PHLX Housing Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, PHLX. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the PHLX Housing Index. PHLX is under no obligation to continue to publish the PHLX Housing Index and may discontinue publication of the PHLX Housing Index at any time.

The PHLX Housing Index is a modified capitalization weighted index composed of twenty companies whose primary lines of business are directly associated with the United States housing construction market (the “PHLX Housing Index Stocks”). The PHLX Housing Index composition encompasses residential builders, suppliers of

A-23

aggregate, lumber and other construction materials, manufactured housing and mortgage insurers. The PHLX Housing Index was set to an initial value of 250 on January 2, 2002. Options commenced trading on the PHLX Housing Index on July 17, 2002. The PHLX split the level of the PHLX Housing Index in half on February 1, 2006. Modified capitalization weighting is intended to maintain as closely as possible the proportional capitalization distribution of the portfolio of PHLX Housing Index Stocks, while limiting the maximum weight of a single stock or group of stocks to a predetermined maximum (normally 25% for a single stock, and 50% to 60% for the top five or an aggregation of all stocks weighing 5% or more). This rebalancing is accomplished by occasionally artificially reducing the capitalization of higher weighted stocks and redistributing the weight to lower weighted stocks without changing the total capitalization of the portfolio. The net result is a weight distribution that is less skewed toward the larger stocks, but still does not approach equal weighting. The PHLX Housing Index value calculation is described by the following formula:

Modified Market Capitalization of the PHLX Housing Index
Base Market Divisor

Modified Capitalization Weighting Methodology for the PHLX Housing Index. PHLX Housing Index securities are first defined as small stocks (current market capitalization less than or equal to 50% of the average market capitalization of all component securities), medium stocks (current market capitalization greater than 50% and less than 150% of the average market capitalization of all component securities), or large stocks (current market capitalization greater than or equal to 150% of the average market capitalization of all component securities).

A determination is then made, based on the current (true) market capitalization if:

| 1. | Any single component security represents 25% or more of the current market capitalization of the basket; and/or
| 2. | All component securities that individually represent 5% or more of the total current market capitalization of the basket in aggregate represent 50% or more of the total current market capitalization of the basket.
If 1 is true, then:
| 3. | The weight of all qualifying component securities is set to 22.5%;
| 4. | The weight that represents the aggregate difference between the original weight and the new weight of 22.5% for each qualifying component is redistributed as follows:

|  | a) | The weight of any component security that represents less than 1% of the total current market capitalization of the basket is increased to exactly 1%, beginning with the highest weighted, sub 1% component security and continuing until either all component securities are equal to or above 1% or until no excess weight remains to be distributed;
|  | b) | Beginning with the largest small stock, its weight is increased to the nearest whole percentage weight, and in one half percentage increments thereafter until the last iteration causes its weight to exceed the weight of the second largest small stock by 100%, and continuing until no excess weight remains to be distributed, except that:

|  |  | i | If the next iteration would cause the subject stock to have a higher weight than the stock ranked immediately above it, the larger stock’s weight is increased to the nearest whole percentage weight and in one half percents increments thereafter until the paused iteration would no longer cause the original subject stock to have a higher weight than the stock ranked immediately above it, until no excess weight remains to be distributed, or until the larger stock’s weight exceeds the stock ranked immediately above it, in which case the step is repeated for the next higher weighted stock.

A-24

If 2 is true after steps 3 and 4, then:

| 5. | The weight of each qualifying component is proportionally reduced such that the aggregate weight of the qualifying components is exactly 45%, as follows:
|  | a) | For qualifying components 1 through n, (a) the difference between 45% and the aggregate weight of all the qualifying components prior to this reduction and (b) the percent of the total capitalization of the qualifying components that each qualifying component represents, is calculated. The weight of each qualifying component is reduced by an amount that equals a *b(1- n) , except that the proportional reduction shall not cause any component to have a lesser weight than the component security ranked immediately beneath it. If such a situation should occur, then the next largest component security or securities that would not have otherwise qualified for inclusion in the proportional reduction shall then be included.

| 6. | The weight that represents the difference between the original aggregate weight and the new weight of 45% for the group of qualifying components is redistributed as follows:
|  | a) | Beginning with the largest small stock, its weight is increased to the nearest whole percentage weight, and in one half percentage increments thereafter until the last iteration causes its weight to exceed the weight of the second largest small stock by 100%, and continuing until no excess weight remains to be distributed, except that:

|  |  | i. | If the next iteration would cause the subject stock to have a higher weight than the stock ranked immediately above it, the larger stock’s weight is increased to the nearest one half percentage weight and in half percent increments thereafter until the paused iteration would no longer cause the original subject stock to have a higher weight than the stock ranked immediately above it, until no excess weight remains to be distributed, or until the larger stock’s weight exceeds the stock ranked immediately above it, in which case this step is repeated for the next higher weighted stock; and
|  |  | ii. | Excess weight distributed to the smallest stock will increase its weight to no more than that of the adjusted weight of the second smallest stock; and
|  |  | iii. | If the smallest stock has been increased to the level of the second smallest stock and excess weight remains to be distributed, then beginning with the largest small stock and continuing downward, the weight of each component is increased by half percentage increments until no excess weight remains, subject to the conditions and remedies of (i) above, except that if insufficient excess weight remains to solve the conditions and remedies of paragraph (i) above, than paragraph (iii) is started with the smallest stock whose weight exceeds the next smallest stock by at least one half percent.

New share values will be assigned to each component security by calculating the dollar value of each component security’s new percent weight of the original total current market capitalization of the basket, divided by the last sale price of each respective component security.

This process will be repeated at least semi-annually for implementation at the end of the January and July option expiration if the modified capitalization of a single component or group of components exceed the concentration thresholds stated above as of the last trading day of the previous month, and such rebalancing will be based on actual market capitalizations of the component stocks as determined by actual share amounts and closing prices on the last trading day of the previous month.

Adjustments for corporate actions are as follows:

> Stock splits – modified share amounts will be adjusted proportionally to the stock price adjustment using the announced split ratio on the effective date of the split. No divisor change should be necessary except for rounding.

A-25

> Share changes greater than 5% – due to mergers, acquisitions, or stock repurchase, modified share amounts will be adjusted in proportion to the announced share change. Divisor changes will be necessary.

Adjustments for stock addition or removal are as follows:

> Stock removal – no adjustments to the remaining component modified shares made. Divisor changes will be necessary.

> Stock addition – the modified share weight of a stock addition will be determined in a 4 step process:

> > > Determine the relative weight rank of the new component’s true capitalization compared to the true capitalization of the current component list (e.g., 14th out of 25);

> > > Assign a modified capitalization to the new component that is midway between the modified capitalization of the two current components that ranked immediately above and below the new component (e.g., midway between the modified cap of numbers 13 and 14);

> > > Determine a number of modified shares required to achieve the modified capitalization based on the closing price of the new component on the day immediately prior to its addition; and

> > > Divisor changes will be necessary.

PHLX Oil Service Sector SM Index

Morgan Stanley has derived all information contained in this prospectus supplement regarding the PHLX Oil Service SectorSM Index (the “PHLX Oil Index”), including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by the Philadelphia Stock Exchange, Inc., which we refer to as the “PHLX.” The PHLX Oil Index was developed by PHLX and is calculated, maintained and published by PHLX. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of such information.

A-26

The PHLX Oil Index is a price-weighted index composed of fifteen companies that provide oil drilling and production services, oil field equipment, support services and geophysical/reservoir services. The PHLX Oil Index was set to an initial value of 75 on December 31, 1996 and options commenced trading on the PHLX Oil Index on February 24, 1997.

The PHLX Oil Index is calculated by adding the prices of the component stocks and dividing by the base market divisor, without any regard to capitalization. Typically, the higher priced and more volatile constituent issues will exert a greater influence over the movement of a price-weighted index. The PHLX Oil Index value calculation is described by the following formula:

Sum of All Component Prices
Base Market Divisor

To maintain the continuity of the PHLX Oil Index, the divisor is adjusted to reflect non-market changes in the price of the component securities as well as changes in the composition of the PHLX Oil Index. Changes which may result in divisor adjustments include but are not limited to stock splits, dividends, spin offs, certain rights issuances and mergers and acquisitions.

License Agreement between the PHLX and Morgan Stanley.

Russell 2000® Index

The Russell 2000® Index is an index calculated, published and disseminated by Frank Russell Company, and measures the composite price performance of stocks of 2,000 companies (the “Russell 2000 Component Stocks”) incorporated in the U.S. and its territories. Morgan Stanley obtained all information contained in this prospectus supplement regarding the Russell 2000 Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, Frank Russell Company. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the Russell 2000 Index. Frank Russell Company is under no obligation to continue to publish the Russell 2000 Index and may discontinue publication of the Russell 2000 Index at any time.

All 2,000 stocks are traded on either the NYSE or the AMEX or in the over-the-counter market and are the 2,000 smallest securities that form the Russell 3000® Index. The Russell 3000 Index is composed of the 3,000

A-27

largest U.S. companies as determined by market capitalization and represents approximately 98% of the U.S. equity market. The Russell 2000 Index consists of the smallest 2,000 companies included in the Russell 3000 Index and represents a small portion of the total market capitalization of the Russell 3000 Index. The Russell 2000 Index is designed to track the performance of the small capitalization segment of the U.S. equity market.

Selection of stocks underlying the Russell 2000 Index. The Russell 2000 Index is a sub-group of the Russell 3000 Index. To be eligible for inclusion in the Russell 3000 Index, and, consequently, the Russell 2000 Index, a company’s stocks must be listed on May 31 of a given year and Frank Russell Company must have access to documentation verifying the company’s eligibility for inclusion. Beginning September 2004, eligible initial public offerings are added to Russell U.S. Indices at the end of each calendar quarter, based on total market capitalization rankings within the market-adjusted capitalization breaks established during the most recent reconstitution. To be added to any Russell U.S. index during a quarter outside of reconstitution, initial public offerings must meet additional eligibility criteria.

Only common stocks belonging to corporations incorporated in the U.S. and its territories are eligible for inclusion in the Russell 3000 Index and, consequently, the Russell 2000 Index. The following securities are specifically excluded from the Russell 2000 Index: (i) stocks traded on U.S. exchanges but incorporated in other countries; (ii) preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights and trust receipts; (iii) royalty trusts, limited liability companies, closed-end investment companies and limited partnerships and (iv) bulletin board, pink sheets or over-the-counter traded securities. In addition, Berkshire Hathaway is excluded as a special exception due to its similarity to a mutual fund and lack of liquidity.

The primary criteria used to determine the initial list of securities eligible for the Russell 3000 Index is total market capitalization, which is defined as the price of the shares times the total number of available shares. All common stock share classes are combined in determining market capitalization. If multiple share classes have been combined, the price of the primary vehicle (usually the most liquid) is used in the calculations. In cases where the common stock share classes act independently of each other (e.g., tracking stocks), each class is considered for inclusion separately. Stocks must trade at or above $1.00 on May 31 of each year to be eligible for inclusion in the Russell 2000 Index. However, if a stock falls below $1.00 intra-year, it will not be removed until the next reconstitution if it is still trading below $1.00.

The Russell 2000 Index is reconstituted annually to reflect changes in the marketplace. The list of companies is ranked based on May 31 total market capitalization, with the actual reconstitution effective on the first trading day following the final Friday of June each year. Changes in the constituents are preannounced and subject to change if any corporate activity occurs or if any new information is received prior to release.

Capitalization Adjustments. As a capitalization-weighted index, the Russell 2000 Index reflects changes in the capitalization, or market value, of the Russell 2000 Component Stocks relative to the capitalization on a base date. The current Russell 2000 Index value is calculated by adding the market values of the Russell 2000 Index’s Russell 2000 Component Stocks, which are derived by multiplying the price of each stock by the number of available shares, to arrive at the total market capitalization of the 2,000 stocks. The total market capitalization is then divided by a divisor, which represents the “adjusted” capitalization of the Russell 2000 Index on the base date of December 31, 1986. To calculate the Russell 2000 Index, last sale prices will be used for exchange-traded stocks. If a component stock is not open for trading, the most recently traded price for that security will be used in calculating the Russell 2000 Index. In order to provide continuity for the Russell 2000 Index’s value, the divisor is adjusted periodically to reflect events including changes in the number of common shares outstanding for Russell 2000 Component Stocks, company additions or deletions, corporate restructurings and other capitalization changes.

Available shares are assumed to be shares available for trading. Exclusion of capitalization held by other listed companies and large holdings of private investors (10% or more) is based on information recorded in corporate filings with the Securities and Exchange Commission. Other sources are used in cases of missing or questionable data.

The following types of shares are considered unavailable for the purposes of capitalization determinations:

> ESOP or LESOP shares – corporations that have Employee Stock Ownership Plans that comprise 10% or more of the shares outstanding are adjusted;

A-28

> Corporate cross-owned shares – when shares of a company in the index are held by another company also in the index, this is considered corporate cross-ownership. Any percentage held in this class will be adjusted;

> Large private and corporate shares – large private and corporate holdings are defined as those shares held by an individual, a group of individuals acting together or a corporation not in the index that own 10% or more of the shares outstanding. However, not to be included in this class are institutional holdings, which are: investment companies, partnerships, insurance companies, mutual funds, banks or venture capitals;

> Unlisted share classes – classes of common stock that are not traded on a U.S. securities exchange; and

> Initial public offering lock-ups – shares locked-up during an initial public offering are not available to the public and will be excluded from the market value at the time the initial public offering enters the index.

Corporate Actions Affecting the Russell 2000 Index. The following summarizes the types of Russell 2000 Index maintenance adjustments and indicates whether or not an index adjustment is required:

> “No Replacement” Rule – Securities that leave the Russell 2000 Index, between reconstitution dates, for any reason (e.g., mergers, acquisitions or other similar corporate activity) are not replaced. Thus, the number of securities in the Russell 2000 Index over the past year will fluctuate according to corporate activity.

> Rule for Deletions – When a stock is acquired, delisted, or moves to the pink sheets or bulletin boards on the floor of a U.S. securities exchange, the stock is deleted from the index at the close on the effective date or when the stock is no longer trading on the exchange. When deleting stocks from the Russell 2000 Index as a result of exchange de-listing or reconstitution, the price used will be the market price on the day of deletion, including potentially the OTC bulletin board price. Previously, prices used to reflect de-listed stocks were the last traded price on the primary exchange. Exceptions exist for certain corporate events, like mergers or acquisitions, that result in the lack of current market price for the deleted security and in such an instance the latest primary exchange closing price available will be used.

> When acquisitions or mergers take place within the Russell 2000 Index, the stock’s capitalization moves to the acquiring stock, hence, mergers have no effect on the index total capitalization. Shares are updated for the acquiring stock at the time the transaction is final.

> Rule for Additions – The only additions between reconstitution dates are as a result of spin-offs and initial public offerings. Spin-off companies are added to the parent company’s index and capitalization tier of membership, if the spin-off is large enough. To be eligible, the spun-off company’s total market capitalization must be greater than the market-adjusted total market capitalization of the smallest security in the Russell 2000 Index at the latest reconstitution.

> Rule for Corporate Action-Driven Changes – Beginning April 1, 2003 changes resulting from corporate actions generally are applied at the open of the ex-date using the previous day’s closing prices. For reclassification of shares, mergers and acquisitions, spin-offs or reorganizations, adjustments will be made at the open of the ex-date using previous day closing prices. For re-incorporations and exchange delisting, deleted entities will be removed at the open on the day following re-incorporation or delisting using previous day closing prices (including OTC prices for delisted stocks).

Updates to Share Capital Affecting the Russell 2000 Index. Each month, the Russell 2000 Index is updated for changes to shares outstanding as companies report changes in share capital to the Securities and Exchange Commission. Effective April 30, 2002, only cumulative changes to shares outstanding greater than 5% will be reflected in the Russell 2000 Index. This does not affect treatment of major corporate events, which are effective on the ex-date.

A-29

Pricing of Securities Included in the Russell 2000 Index. Effective on January 1, 2002, primary exchange closing prices are used in the daily index calculations. FT Interactive data is used as the primary source for U.S. security prices, income, and total shares outstanding. Prior to January 1, 2002, composite closing prices, which are the last trade price on any U.S. exchange, were used in the daily index calculations.

S&P 500® Index

The S&P 500® Index was developed by Standard & Poor’s® Corporation, which we refer to as S&P®, and is calculated, maintained and published by S&P. Morgan Stanley obtained all information contained in this prospectus supplement regarding the S&P 500 Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, S&P. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the S&P 500 Index. S&P is under no obligation to continue to publish the S&P 500 Index and may discontinue publication of the S&P 500 Index at any time.

The S&P 500 Index is intended to provide a performance benchmark for the U.S. equity markets. The calculation of the value of the S&P 500 Index (discussed below in further detail) is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 500 companies (the “S&P 500 Component Stocks”) as of a particular time as compared to the aggregate average Market Value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. The “Market Value” of any S&P 500 Component Stock is the product of the market price per share and the number of the then outstanding shares of such S&P 500 Component Stock. The 500 companies are not the 500 largest companies listed on the NYSE and not all 500 companies are listed on such exchange. S&P chooses companies for inclusion in the S&P 500 Index with an aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the U.S. equity market. S&P may from time to time, in its sole discretion, add companies to, or delete companies from, the S&P 500 Index to achieve the objectives stated above. Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the company’s common stock is widely-held and the Market Value and trading activity of the common stock of that company.

The S&P 500 Index is calculated using a base-weighted aggregate methodology: the level of the S&P 500 Index reflects the total Market Value of all 500 S&P 500 Component Stocks relative to the S&P 500 Index’s base period of 1941-43 (the “Base Period”).

An indexed number is used to represent the results of this calculation in order to make the value easier to work with and track over time.

The actual total Market Value of the S&P 500 Component Stocks during the Base Period has been set equal to an indexed value of 10. This is often indicated by the notation 1941-43=10. In practice, the daily calculation of the S&P 500 Index is computed by dividing the total Market Value of the S&P 500 Component Stocks by a number called the “S&P 500 Index Divisor.” By itself, the S&P 500 Index Divisor is an arbitrary number. However, in the context of the calculation of the S&P 500 Index, it is the only link to the original base period value of the S&P 500 Index. The S&P 500 Index Divisor keeps the S&P 500 Index comparable over time and is the manipulation point for all adjustments to the S&P 500 Index (“S&P 500 Index Maintenance”).

S&P 500 Index Maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructurings or spinoffs.

To prevent the value of the S&P 500 Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the S&P 500 Index require a S&P 500 Index Divisor adjustment. By adjusting the S&P 500 Index Divisor for the change in total Market Value, the value of the S&P 500 Index remains constant. This helps maintain the value of the S&P 500 Index as an accurate barometer of stock market performance and ensures that the movement of the S&P 500 Index does not reflect the corporate actions of individual companies in the S&P 500 Index. All S&P 500 Index Divisor adjustments are made after the close of trading and after the calculation of the closing value of the S&P 500 Index. Some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the S&P 500 Index and do not require S&P 500 Index Divisor adjustments.

The table below summarizes the types of S&P 500 Index maintenance adjustments and indicates whether or not a S&P 500 Index Divisor adjustment is required:

A-31

|  |  |  |  | Divisor |
| Type of Corporate |  |  |  | Adjustment |
| Action |  | Adjustment Factor |  | Required |
| Stock split |  | Shares Outstanding multiplied by 2; |  | No |
| (i.e., 2-for-1) |  | Stock Price divided by 2 |  |  |
| Share issuance |  | Shares Outstanding plus newly |  | Yes |
| (i.e., change ≥ 5%) |  | issued Shares |  |  |
| Share repurchase |  | Shares Outstanding minus |  | Yes |
| (i.e., change ≥ 5%) |  | Repurchased Shares |  |  |
| Special cash dividends |  | Share Price minus Special Dividend |  | Yes |
| Company Change |  | Add new company Market Value |  | Yes |
|  |  | minus old company Market Value |  |  |
| Rights Offering |  | Price of parent company minus |  | Yes |
|  |  | Price of Rights Right Ratio |  |  |
| Spin-Off |  | Price of parent company minus |  | Yes |
|  |  | Price of Spinoff Co. Share Exchange Ratio |  |  |

Stock splits and stock dividends do not affect the S&P 500 Index Divisor of the S&P 500 Index, because following a split or dividend both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the S&P 500 Component Stock. All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

Each of the corporate events exemplified in the table requiring an adjustment to the S&P 500 Index Divisor has the effect of altering the Market Value of the S&P 500 Component Stock and consequently of altering the aggregate Market Value of the S&P 500 Component Stocks (the “Post-Event Aggregate Market Value”). In order that the level of the S&P 500 Index (the “Pre-Event Index Value”) not be affected by the altered Market Value (whether increase or decrease) of the affected S&P 500 Component Stock, a new S&P 500 Index Divisor (“New S&P 500 Divisor”) is derived as follows:

A large part of the S&P 500 Index maintenance process involves tracking the changes in the number of shares outstanding of each of the S&P 500 Index companies. Four times a year, on a Friday close to the end of each calendar quarter, the share totals of companies in the S&P 500 Index are updated as required by any changes in the number of shares outstanding. After the totals are updated, the S&P 500 Index Divisor is adjusted to compensate for the net change in the total Market Value of the S&P 500 Index. In addition, any changes over 5% in the current common shares outstanding for the S&P 500 Index companies are carefully reviewed on a weekly basis, and when appropriate, an immediate adjustment is made to the S&P 500 Index Divisor.

The S&P 500 Index and S&P’s other U.S. indices moved to a float adjustment methodology in 2005 so that the indices will reflect only those shares that are generally available to investors in the market rather than all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by other publicly traded companies, venture capital firms, private equity firms, strategic partners or leveraged buyout groups; government entities; or other control groups, such as a company’s own current or former officers, board members, founders,

A-32

employee stock ownership plans or other investment vehicles controlled by the company or such other persons. In March 2005 the official S&P U.S. indices moved half way to float adjustment and in September 2005 the indices will move to full float adjustment.

License Agreement between S&P and Morgan Stanley. S&P and Morgan Stanley have entered into a non-exclusive license agreement providing for the license to Morgan Stanley, and certain of its affiliated or subsidiary companies, in exchange for a fee, of the right to use the S&P 500 Index, which is owned and published by S&P, in connection with securities, including the leveraged index-linked securities.

The license agreement between S&P and Morgan Stanley provides that the following language must be set forth in this prospectus supplement:

The leveraged index-linked securities are not sponsored, endorsed, sold or promoted by S&P. S&P makes no representation or warranty, express or implied, to the owners of the leveraged index-linked securities or any member of the public regarding the advisability of investing in securities generally or in the leveraged index-linked securities particularly or the ability of the S&P 500 Index to track general stock market performance. S&P’s only relationship to us is the licensing of certain trademarks and trade names of S&P and of the S&P 500 Index, which is determined, composed and calculated by S&P without regard to us or the leveraged index-linked securities. S&P has no obligation to take our needs or the needs of the owners of the leveraged index-linked securities into consideration in determining, composing or calculating the S&P 500 Index. S&P is not responsible for and has not participated in the determination of the timing of, prices at, or quantities of the leveraged index-linked securities to be issued or in the determination or calculation of the equation by which the leveraged index-linked securities are to be converted into cash. S&P has no obligation or liability in connection with the administration, marketing or trading of the leveraged index-linked securities.

S&P DOES NOT GUARANTEE THE ACCURACY AND/OR THE COMPLETENESS OF THE S&P 500 INDEX OR ANY DATA INCLUDED THEREIN. S&P MAKES NO WARRANTY, EXPRESS OR IMPLIED, AS TO RESULTS TO BE OBTAINED BY MORGAN STANLEY, OWNERS OF THE LEVERAGED INDEX-LINKED SECURITIES, OR ANY OTHER PERSON OR ENTITY FROM THE USE OF THE S&P 500 INDEX OR ANY DATA INCLUDED THEREIN IN CONNECTION WITH THE RIGHTS LICENSED UNDER THE LICENSE AGREEMENT DESCRIBED HEREIN OR FOR ANY OTHER USE. S&P MAKES NO EXPRESS OR IMPLIED WARRANTIES, AND HEREBY EXPRESSLY DISCLAIMS ALL WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR USE WITH RESPECT TO THE S&P 500 INDEX OR ANY DATA INCLUDED THEREIN. WITHOUT LIMITING ANY OF THE FOREGOING, IN NO EVENT SHALL S&P HAVE ANY LIABILITY FOR ANY SPECIAL, PUNITIVE, INDIRECT OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS), EVEN IF NOTIFIED OF THE POSSIBILITY OF SUCH DAMAGES.

S&P 100® Index

The S&P 100® Index is calculated, maintained and published by S&P. Morgan Stanley obtained all information contained in this prospectus supplement regarding the S&P 100 Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, S&P. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the S&P 100 Index. S&P is under no obligation to continue to publish the S&P 100 Index and may discontinue publication of the S&P 100 Index at any time.

The S&P 100 Index is a subset of the S&P 500 Index and comprises 100 leading U.S. stocks with exchange-listed options. Constituents of the S&P 100 Index are selected for sector balance. The calculation of the value of the S&P 100 Index (discussed below in further detail) is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 100 companies (the “S&P 100 Component Stocks”) as of a particular time as compared to the aggregate average Market Value of the common stocks of 100 similar companies during the

A-33

base period. The “Market Value” of any S&P 100 Component Stock is the product of the market price per share and the number of the then outstanding shares of such S&P 100 Component Stock.

The S&P 100 Index was originally developed by the Chicago Board Options Exchange (CBOE), which later transferred the S&P 100 Index to S&P for management. S&P’s U.S. Index Committee, which oversees the S&P 500 Index and other S&P equity indices, maintains the S&P 100 Index. Because the S&P 100 Index is derived from the S&P 500 Index, the S&P 100 Index stocks are also subject to the published S&P 500 criteria for additions and deletions. In addition, only companies included in the S&P 500 Index are eligible for inclusion in the S&P 100 Index. All stocks added to the S&P 100 Index must maintain exchange-listed options. Stocks included in the S&P 100 Index must also meet the S&P U.S. Index Committee’s guidelines for sector representation. The sector composition of the S&P 100 Index has remained comparable to the sector composition of the S&P 500 Index. The S&P U.S. Index Committee may remove a company from the S&P 100 Index if the company does not meet the inclusion qualifications or if the index becomes unbalanced in its sector representation. The S&P U.S. Index Committee may also remove any company that violates any of the S&P 500 criteria.

The S&P 100 Index is calculated using a base-weighted aggregate methodology where the level of the S&P 100 Index reflects the total Market Value of all 100 S&P 100 Component Stocks relative to the S&P 100 Index’s base period.

An indexed number is used to represent the results of this calculation in order to make the value easier to work with and track over time.

The daily calculation of the S&P 100 Index is computed by dividing the total Market Value of the S&P 100 Component Stocks by a number called the “S&P 100 Index Divisor.” By itself, the S&P 100 Index Divisor is an arbitrary number. However, in the context of the calculation of the S&P 100 Index, it is the only link to the original base period value of the S&P 100 Index. The S&P 100 Index Divisor keeps the S&P 100 Index comparable over time and is the manipulation point for all adjustments to the S&P 100 Index (“S&P 100 Index Maintenance”).

S&P 100 Index Maintenance includes monitoring and completing adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock-price adjustments due to company restructurings or spinoffs.

To prevent the value of the S&P 100 Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the S&P 100 Index require a S&P 100 Index Divisor adjustment. By adjusting the S&P 100 Index Divisor for the change in total Market Value, the value of the S&P 100 Index remains constant. This helps maintain the value of the S&P 100 Index as an accurate barometer of stock market performance and ensures that the movement of the S&P 100 Index does not reflect the corporate actions of individual companies in the S&P 100 Index. All S&P 100 Index Divisor adjustments are made after the close of trading and after the calculation of the index closing value of the S&P 100 Index. Some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the S&P 100 Index and do not require S&P 100 Index Divisor adjustments.

The table below summarizes the types of S&P 100 Index maintenance adjustments and indicates whether or not a S&P 100 Index Divisor adjustment is required:

|  |  |  |  | Divisor |
| Type of Corporate |  |  |  | Adjustment |
| Action |  | Adjustment Factor |  | Required |
| Stock split |  | Shares Outstanding multiplied by 2; |  | No |
| (i.e., 2-for-1) |  | Stock Price divided by 2 |  |  |
| Share issuance |  | Shares Outstanding plus newly |  | Yes |
| (i.e., change ≥ 5%) |  | issued Shares |  |  |

A-34

| Share repurchase |  | Shares Outstanding minus |  | Yes |
| (i.e., change ≥ 5%) |  | Repurchased Shares |  |  |
| Special cash dividends |  | Share Price minus Special Dividend |  | Yes |
| Company Change |  | Add new company Market Value |  | Yes |
|  |  | minus old company Market Value |  |  |
| Rights Offering |  | Price of parent company minus |  | Yes |
|  |  | Price of Rights Right Ratio |  |  |
| Spin-Off |  | Price of parent company minus |  | Yes |
|  |  | Price of Spinoff Co. Share Exchange Ratio |  |  |

Stock splits and stock dividends do not affect the S&P 100 Index Divisor of the S&P 100 Index, because following a split or dividend both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the S&P 100 Component Stock. All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

Each of the corporate events exemplified in the table requiring an adjustment to the S&P 100 Index Divisor has the effect of altering the Market Value of the S&P 100 Component Stock and consequently of altering the aggregate Market Value of the S&P 100 Component Stocks (the “Post-Event Aggregate Market Value”). In order that the level of the S&P 100 Index (the “Pre-Event Index Value”) not be affected by the altered Market Value (whether increase or decrease) of the affected S&P 100 Component Stock, a new S&P 100 Index Divisor (“New S&P 100 Divisor”) is derived as follows:

A large part of the S&P 100 Index maintenance process involves tracking the changes in the number of shares outstanding of each of the S&P 100 Index companies. Four times a year, on a Friday close to the end of each calendar quarter, the share totals of companies in the S&P 100 Index are updated as required by any changes in the number of shares outstanding. After the totals are updated, the S&P 100 Index Divisor is adjusted to compensate for the net change in the total Market Value of the S&P 100 Index. In addition, any changes over 5% in the current common shares outstanding for the S&P 100 Index companies are carefully reviewed on a weekly basis, and when appropriate, an immediate adjustment is made to the S&P 100 Index Divisor.

The S&P 100 Index and S&P’s other U.S. indices moved to a float adjustment methodology in 2005 so that the indices will reflect only those shares that are generally available to investors in the market rather than all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by other publicly traded companies, venture capital firms, private equity firms, strategic partners or leveraged buyout groups; government entities; or other control groups, such as a company’s own current or former officers, board members, founders, employee stock ownership plans or other investment vehicles controlled by the company or such other persons. In March 2005 the official S&P U.S. indices moved half way to float adjustment and in September 2005 the indices will move to full float adjustment.

S&P 400® (Midcap) Index

Morgan Stanley obtained all information contained in this prospectus supplement regarding the S&P 400® (Midcap) Index, which we refer to as the S&P MidCap Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, S&P. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of any information relating to the S&P MidCap Index. S&P is under no obligation to continue to publish the S&P MidCap Index and may discontinue publication of the S&P MidCap Index at any time.

The S&P MidCap Index is published by S&P and is intended to provide a benchmark for performance measurement of the medium capitalization segment of the U.S. equity markets. It tracks the stock price movement of 400 companies with mid-sized market capitalizations, primarily ranging from $1 billion to $4 billion. The calculation of the value of the S&P MidCap Index (discussed below in further detail) is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 400 companies (the “S&P Midcap Component Stocks”) as of a particular time as compared to the aggregate average Market Value of the common stocks of 400 similar companies during the base period of June 28, 1991. The “Market Value” of any S&P Midcap Component Stock is the product of the market price per share and the number of the then outstanding shares of such S&P Midcap Component Stock. S&P chooses companies for inclusion in the S&P MidCap Index with an aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the medium capitalization segment of the U.S. equity market. S&P may from time to time, in its sole discretion, add companies to, or delete companies from, the S&P MidCap Index to achieve the objectives stated above. Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the company’s common stock is widely held and the Market Value and trading activity of the common stock of that company.

A-36

The S&P MidCap Index is calculated using a base-weighted aggregate methodology: the level of the S&P MidCap Index reflects the total Market Value of all 400 S&P Midcap Component Stocks relative to the S&P MidCap Index’s base period of June 28, 1991 (the “Base Period”). An indexed number is used to represent the results of this calculation in order to make the value easier to work with and track over time.

The actual total Market Value of the S&P Midcap Component Stocks during the Base Period has been set equal to an indexed value of 100. This is often indicated by the notation June 28, 1991=100. In practice, the daily calculation of the S&P MidCap Index is computed by dividing the total Market Value of the S&P Midcap Component Stocks by a number called the “S&P MidCap Index Divisor.” By itself, the S&P MidCap Index Divisor is an arbitrary number. However, in the context of the calculation of the S&P MidCap Index, it is the only link to the original base period value of the S&P MidCap Index. The S&P MidCap Index Divisor keeps the S&P MidCap Index comparable over time and is the manipulation point for all adjustments to the S&P MidCap Index (“S&P MidCap Index Maintenance”). S&P MidCap Index Maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spinoffs.

To prevent the value of the S&P MidCap Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the S&P MidCap Index require a S&P MidCap Index Divisor adjustment. By adjusting the S&P MidCap Index Divisor for the change in total Market Value, the value of the S&P MidCap Index remains constant. This helps maintain the value of the S&P MidCap Index as an accurate barometer of stock market performance and ensures that the movement of the S&P MidCap Index does not reflect the corporate actions of individual companies in the S&P MidCap Index. All S&P MidCap Index Divisor adjustments are made after the close of trading and after the calculation of the index closing value of the S&P MidCap Index. Some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the S&P MidCap Index and do not require S&P MidCap Index Divisor adjustments.

The table below summarizes the types of S&P MidCap Index maintenance adjustments and indicates whether or not a S&P MidCap Index Divisor adjustment is required.

| Type of Corporate Action |  | Adjustment Factor |  | Divisor Adjustment Required |
| Stock split |  | Shares Outstanding |  |  |
| (i.e., 2-for-1) |  | multiplied by 2; Stock Price |  |  |
|  |  | divided by 2 |  | No |
| Share issuance |  | Shares Outstanding plus |  |  |
| (i.e., change > 5%) |  | newly issued Shares |  | Yes |
| Share repurchase |  | Shares Outstanding minus |  |  |
| (i.e., change > 5%) |  | Repurchased Shares |  | Yes |
| Special cash |  | Share Price minus Special |  |  |
| dividends |  | Dividend |  | Yes |
| Company change |  | Add new company Market |  |  |
|  |  | Value minus old company |  |  |
|  |  | Market Value |  | Yes |
| Rights offering |  | Price of parent company |  |  |
|  |  | minus |  |  |
|  |  | Price of Rights |  |  |
|  |  | Right Ratio |  | Yes |
| Spin-Off |  | Price of parent company |  |  |
|  |  | minus |  |  |
|  |  | Price of Spinoff Co. |  |  |
|  |  | Share Exchange Ratio |  | Yes |

Stock splits and stock dividends do not affect the S&P MidCap Index Divisor of the S&P MidCap Index, because following a split or dividend both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the S&P Midcap Component Stock. All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

Each of the corporate events exemplified in the table requiring an adjustment to the S&P MidCap Index Divisor has the effect of altering the Market Value of the S&P Midcap Component Stock and consequently of altering the aggregate Market Value of the S&P Midcap Component Stocks (the “Post-Event Aggregate Market Value”). In order that the level of the S&P MidCap Index (the “Pre-Event Index Value”) not be affected by the altered Market Value (whether increase or decrease) of the affected S&P Midcap Component Stock, a new S&P MidCap Index Divisor (“New S&P MidCap Divisor”) is derived as follows:

Four times a year, on a Friday near the end of each calendar quarter, the share totals of companies in the S&P MidCap Index are updated as required by any changes in the number of shares outstanding. After the totals are updated, the S&P MidCap Index Divisor is adjusted to compensate for the net change in the total Market Value of the S&P MidCap Index.

Tokyo Stock Price Index

The Tokyo Stock Price Index (the “TOPIX Index®”) is published by Tokyo Stock Exchange, Inc. (“TSE”). Morgan Stanley has derived all information regarding the TOPIX Index, including its method of calculation, from publicly available sources, including the websites of the Tokyo Stock Exchange and other sources it believes to be reliable. Morgan Stanley makes no representation or warranty as to the accuracy or completeness of such information, nor incorporate any such information into this prospectus supplement.

The TOPIX Index was developed by the TSE. Publication of the TOPIX Index began on July 1, 1969, based on a base index value of 100 as of January 4, 1968. The TOPIX Index is computed and published every 15 seconds via TSE’s Market Information System, and is reported to securities companies across Japan and available worldwide through computerized information networks.

The component stocks of the TOPIX Index consist of all common domestic stocks listed on the First Section of the TSE which have an accumulative length of listing of at least six months. The TOPIX Index measures changes in the aggregate market value of these stocks. The TSE domestic stock market is divided into two sections: the First Section and the Second Section. Listings of stocks on the TSE are divided between these two sections, with stocks listed on the First Section typically being limited to larger, longer established and more actively traded issues and the Second Section to smaller and newly listed companies. The component stocks of the TOPIX Index are determined based on market capitalization and liquidity. Review and selection of component stocks is conducted semiannually, based on market data as of the base date for selection.

The TOPIX Index is a free float adjusted market capitalization weighted index, with the market price of each component stock multiplied by the number of shares listed (as adjusted by multiplying the Free-Float Weight (“FFW”) to take into account only the listed shares deemed to be available for trading in the market). The TSE is responsible for calculating and maintaining the TOPIX Index, and can add, delete or substitute the stocks underlying the TOPIX Index or make other methodological changes that could change the value of the TOPIX Index. The underlying stocks may be removed, if necessary, in accordance with deletion/addition rules which provide generally for the deletion of a stock from the TOPIX Index if such stock ceases to meet the criteria for inclusion. Stocks listed on the Second Section of the TSE may be transferred to the First Section if they satisfy applicable criteria. Such criteria include numerical minimum values for number of shares listed, number of shareholders and average monthly trading volume, among others. Similarly, when a First Section stock falls within the coverage of TSE rules prescribing reassignment thereof to the Second Section, such stock will be removed from the First Section.

The TOPIX Index is not expressed in Japanese Yen, but is presented in terms of points (as a decimal figure) rounded off to the nearest one-hundredth. The TOPIX Index is calculated by multiplying 100 by the figure obtained by dividing the current free-float adjusted market value (the current market price per share at the time of the index calculation multiplied by the number of common shares listed on the First Section of the TSE at the same instance

A-39

(as adjusted by multiplying the FFW)) (the “TOPIX Current Market Value”) by the base market value (i.e., the TOPIX Current Market Value on the base date) (the “TOPIX Base Market Value”).

The calculation of the TOPIX Index can be represented by the following formula:

In order to maintain continuity, the TOPIX Base Market Value is adjusted from time to time to ensure that it reflects only price movements resulting from auction market activity, and to eliminate the effects of other factors and prevent any instantaneous change or discontinuity in the level of the TOPIX Index. Such factors include, without limitation: new listings; delistings; new share issues either through public offerings or through rights offerings to shareholders; issuance of shares as a consequence of exercise of convertible bonds or warrants; and transfer of listed securities from the First Section to the Second Section of the TSE.

The formula for the adjustment is as follows:

Where, adjustment amount is equal to the changes in the number of shares included in the calculation of the index multiplied by the price of those shares used for the purposes of the adjustment.

Therefore,

The TOPIX Base Market Value remains at the new value until a further adjustment is necessary as a result of another change. As a result of such change affecting the TOPIX Current Market Value or any stock underlying the TOPIX Index, the TOPIX Base Market Value is adjusted in such a way that the new value of the TOPIX Index will equal the level of the TOPIX Index immediately prior to such change.

No adjustment is made to the TOPIX Base Market Value, however, in the case of events such as stock splits or decreases in capital without compensation, which theoretically do not affect market value.

License Agreement between TSE and Morgan Stanley. Morgan Stanley has entered into a non-exclusive license agreement with TSE providing for the license to Morgan Stanley, and certain of its affiliated or subsidiary companies, in exchange for a fee, of the right to use the TOPIX Index, which is owned and published by the TSE, in connection with securities, including the leveraged index-linked securities.
