Reverse of Security

This Security is one of a duly authorized series of Securities of the Company designated as Bearish Return Optimization Securities with Partial Protection Linked to the iShares® Dow Jones U.S. Real Estate Index Fund Due August 29, 2008 (herein called the “Securities”). The Company may, without the consent of the holders of the Securities, create and issue additional notes ranking equally with the Securities and otherwise similar in all respects so that such further notes shall be consolidated and form a single series with the Securities; provided that no additional notes can be issued if an Event of Default has occurred with respect to the Securities. This series of Securities is one of an indefinite number of series of debt securities of the Company, issued and to be issued under an indenture, dated as of September 1, 1987, as amended (herein called the “Indenture”), duly executed and delivered by the Company and Citibank, N.A., as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities.

The Payment at Maturity, at the request of the Trustee, shall be determined by the Calculation Agent pursuant to the Calculation Agency Agreement. The Trustee shall fully rely on the determination by the Calculation Agent of the Payment at Maturity and shall have no duty to make any such determination. The Calculation Agent will provide written notice to the Trustee at its New York office, on which notice the Trustee may conclusively rely, of the Payment at Maturity on or prior to 11:00 a.m. on the Business Day preceding the Maturity Date.

All calculations with respect to the Initial Share Price, any Closing Price of one share of the Index Fund, the Share Adjustment Factor, the Final Share Price and the Share Return will be rounded to the nearest one hundred-thousandth, with five one-millionths rounded upward (e.g., .876545 would be rounded to .87655); all dollar amounts related to determination of the payment per $10 principal amount Security, if any, at maturity 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 principal amount of Securities per Holder will be rounded to the nearest cent, with one-half cent rounded upward.

This Security is not subject to any sinking fund.

If an Event of Default with respect to the Securities shall occur and be continuing, the amounts payable on all of the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under the Indenture will be equal to the Payment at Maturity calculated as though the date of acceleration were the Maturity Date and the third Business Day immediately preceding the date of acceleration were the Final Valuation Date. If the maturity of the Securities is accelerated because of an Event of Default, the Company 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 The Depository Trust Company of the cash amount due with respect to the Securities as promptly as possible and in no event later than two Business Days after the date of acceleration.

1

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than 66 ²/3% in aggregate principal amount of each series of Securities at the time Outstanding to be affected (each series voting as a class), evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to, or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Securities of all such series; provided, however, that no such supplemental indenture shall, among other things, (i) change the fixed maturity of any Security, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, if any, or reduce any premium payable on redemption, or make the principal thereof, or premium, if any, or interest thereon, if any, payable in any coin or currency other than that hereinabove provided, without the consent of the holder of each Security so affected, or (ii) change the place of payment on any Security, or impair the right to institute suit for payment on any Security, or reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of each Security so affected. It is also provided in the Indenture that, prior to any declaration accelerating the maturity of any series of Securities, the holders of a majority in aggregate principal amount of the Securities of such series Outstanding may on behalf of the holders of all the Securities of such series waive any past default or Event of Default under the Indenture with respect to such series and its consequences, except a default in the payment of interest, if any, or the principal of, or premium, if any, on any of the Securities of such series, or in the payment of any sinking fund installment or analogous obligation with respect to Securities of such series. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future holders and owners of this Security and any Securities which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Payment at Maturity with respect to this Security.

The Securities are issuable in denominations of $10 and any whole multiples of $10.

The Company, the Trustee, and any agent of the Company or of the Trustee may deem and treat the registered holder (the “Holder”) hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment hereof, or on account hereof, and for all other purposes and neither the Company nor the Trustee nor any agent of the Company or of the Trustee shall be affected by any notice to the contrary. All such payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, effectually satisfy and discharge liability for moneys payable on this Security.

No recourse for the payment of the principal of, premium, if any, or interest on this Security, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as

2

such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office or agency in a Place of Payment for this Security, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Securities of this series or of like tenor and of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Company intends to treat, and by purchasing this Security, the Holder agrees to treat, for all tax purposes, this Security as a cash-settled financial contract, rather than as a debt instrument.

Calculation Agent

The Calculation Agent will determine, among other things, the Initial Share Price, the Closing Price, as applicable, of one share of the Index Fund with respect to each Trading Day for the purposes of determining the Share Adjustment Factor and anti-dilution adjustments, if any, the Final Share Price, the Share Return and the Payment at Maturity, if any. The Calculation Agent will also be responsible for determining, among other things, whether a Market Disruption Event has occurred, which exchange traded fund will be substituted for the Index Fund (or Successor Index Fund, if applicable) if the Index Fund (or Successor Index Fund, if applicable) is de-listed, liquidated or otherwise terminated, whether the Underlying Index (or the underlying index related to a Successor Index Fund) has been changed in a material respect,

8

and whether the Index Fund (or Successor Index Fund, if applicable) has been modified so that the Index Fund (or Successor Index Fund, if applicable) does not, in the opinion of the Calculation Agent, fairly represent the price of the Index Fund (or Successor Index Fund, if applicable) had those modifications not been made. All calculations, determinations and adjustments 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 Holders and on the Company. The Company may appoint a different Calculation Agent from time to time after the date of the original issue of the Securities without the Holders’ consent and without notifying Holders.

Anti-Dilution Adjustments

Share Splits and Reverse Share Splits

If the shares of the Index Fund are subject to a share split or reverse share split, then once such split has become effective, the Share Adjustment Factor will be adjusted so that the new Share Adjustment Factor shall equal the product of:

Share Dividends or Distributions

If the Index Fund is subject to a (i) share dividend, i.e., an issuance of additional shares of the Index Fund that is given ratably to all or substantially all holders of shares of the Index Fund or (ii) distribution of shares of the Index Fund as a result of the triggering of any provision of the corporate charter of the Index Fund, then, once the dividend or distribution has become effective and the shares of the Index Fund are trading ex-dividend, the Share Adjustment Factor will be adjusted so that the new Share Adjustment Factor shall equal the prior Share Adjustment Factor plus the product of:

Non-cash Distributions

If the Index Fund distributes shares of capital stock, evidences of indebtedness or other assets or property of the Index Fund to all or substantially all holders of shares of the Index Fund (other than (i) share dividends or distributions referred to under “—Share Dividends or Distributions” above and (ii) cash dividends referred under “—Cash Dividends or Distributions” below), then, once the distribution has become effective and the shares of the Index Fund are trading ex-dividend, the Share Adjustment Factor will be adjusted so that the new Share Adjustment Factor shall equal the product of:

9

The “Current Market Price” of the Index Fund means the arithmetic average of the Closing Prices of one share of the Index Fund for the ten Trading Days prior to the Trading Day immediately preceding the ex-dividend date of the distribution requiring an adjustment to the Share Adjustment Factor.

The “ex-dividend date” shall mean the first Trading Day on which transactions in the shares of the Index Fund trade on the Relevant Exchange without the right to receive that dividend or distribution.

The “Fair Market Value” of any such distribution means the value of such distribution on the ex-dividend date for such distribution, as determined by the Calculation Agent. If such distribution consists of property traded on the ex-dividend date on a U.S. national securities exchange, the Fair Market Value will equal the closing price of such distributed property on such ex-dividend date.

Cash Dividends or Distributions

If the issuer of any shares of the Index Fund pays dividends or makes other distributions consisting exclusively of cash to all or substantially all holders of shares of the Index Fund during any fiscal quarter during the term of the Securities, in an aggregate amount that, together with other such dividends or distributions made during such quarterly fiscal period, exceeds the Dividend Threshold, then, once the dividend or distribution has become effective and the shares of the Index Fund are trading ex-dividend, the Share Adjustment Factor will be adjusted so that the new Share Adjustment Factor shall equal the product of:

“Dividend Threshold” shall mean the amount of any cash dividend or cash distribution distributed per share of the Index Fund that exceeds the immediately preceding cash dividend or other cash distribution, if any, per share of the Index Fund by more than 10% of the Closing Price of the Index Fund on the Trading Day immediately preceding the ex-dividend date.

The Calculation Agent will provide information as to any adjustments to the Share Adjustment Factor upon written request by any Holder.

10

Alternative Calculation of Closing Price

If the Index Fund (or a Successor Index Fund (as defined herein) is de-listed from the NYSE (or any other Relevant Exchange), liquidated or otherwise terminated, the Calculation Agent will substitute an exchange traded fund that the Calculation Agent determines, in its sole discretion, is comparable to the discontinued Index Fund (or such successor index fund) (such index fund being referred to herein as a “Successor Index Fund”). If the Index Fund (or a Successor Index Fund) is de-listed, liquidated or otherwise terminated and the Calculation Agent determines that no Successor Index Fund is available, then the Calculation Agent will, in its sole discretion, calculate the appropriate Closing Price of the shares of the Index Fund (or a Successor Index Fund) by a computation methodology that the Calculation Agent determines will as closely as reasonably possible replicate the Index Fund (or a Successor Index Fund). If a Successor Index Fund is selected or the Calculation Agent calculates a Closing Price by a computation methodology that the Calculation Agent determines will as closely as reasonably possible replicate the Index Fund (or a Successor Index Fund), that Successor Index Fund or Closing Price, as applicable, will be substituted for the Index Fund (or such Successor Index Fund) for all purposes of the Securities.

If at any time:

then, from and after that time, the Calculation Agent will make those calculations and adjustments as, in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a Closing Price of an exchange traded fund comparable to the Index Fund (or such Successor Index Fund) as if those changes or modifications had not been made, and calculate the Closing Price with reference to the shares of the Index Fund (or such Successor Index Fund), as adjusted. The Calculation Agent also may determine that no adjustment is required by the modification of the method of calculation.

The Calculation Agent will provide information as to the method of calculating the Closing Price of the shares of the Index Fund (or such Successor Index Fund) upon written request by any Holder.
