 Reverse of Security 
 This Security is one of a duly authorized series of Securities of the Company designated as Return Optimization Securities with Partial Protection Linked to the S&P 500® Index Due May 6, 2009 (herein called the “Securities”). The Company may, without the consent of the holders of the Securities, create and issue additional securities ranking equally with the
Securities and otherwise similar in all respects so that such additional securities shall be consolidated and form a single series with the Securities; provided that no additional securities 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 Index Ending Level and the Index Return or any Index Closing Level 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 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 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.

  







 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 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. 
 THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK. 
 Definitions 
 Set forth below are definitions of the terms used in this Security. 
 “Business Day”,
notwithstanding any provision in the Indenture, shall mean any day that is not a Saturday or Sunday and that is not a day on which banking institutions in the City of New York are authorized or obligated by law to close. 
 “Calculation Agency Agreement” shall mean the Calculation Agency Agreement, dated as of December 21, 2006 between the Company and
the Calculation Agent, as amended from time to time, or any successor calculation agency agreement. 
 “Calculation Agent”
shall mean the person that has entered into an agreement with the Company providing for, among other things, the determination of the Payment at Maturity, which term shall, unless the context otherwise requires, include its successors and assigns.
The initial Calculation Agent shall be Lehman Brothers Inc. 
 “Closing Price” of a security, on any particular day, means
the last reported sales price for that security on the Relevant Exchange at the scheduled weekday closing time of the regular trading session of the Relevant Exchange. If, however, the security is not listed or traded on a bulletin board, then the
Closing Price of the security will be determined using the average execution price per share that an affiliate of the Company pays or receives upon the purchase or sale of the security used to hedge the Company’s obligations under the
Securities. 
  







 “Company” shall have the meaning set forth on the face of this Security. 
 “Holder” shall have the meaning set forth on the reverse of this Security. 
 “Indenture” shall have the meaning set forth on the reverse of this Security. 
 “Index” shall mean the S&P 500® Index, as calculated, published and
disseminated by S&P. 
 “Index Closing Level”, as determined by the Calculation Agent, shall mean, with respect to any
Trading Day, the closing level of the Index or the Successor Index, as the case may be, at the regular official weekday close of the principal trading session of the Relevant Exchange or market for the Index or the Successor Index, as the case may
be, on such day, or as determined by the Calculation Agent pursuant to the Calculation Agency Agreement as described below under “Discontinuation of the Index; Alteration of Method of Calculation.” 
 “Index Ending Level” shall equal the Index Closing Level on the Valuation Date. 
 “Index Return”, as calculated by the Calculation Agent, is calculated as follows: 
 Index Ending Level – Index Starting Level 
 Index Starting Level 
 “Index Sponsor”, with respect to the Index, shall be Standard & Poor’s
(“S&P”), a division of The McGraw-Hill Companies, Inc. The Calculation Agent, in its sole discretion, may select a new Index Sponsor as described under “Discontinuation of the Index; Alteration of Method of Calculation.”

 “Index Starting Level” shall equal 1,509.65. 
 “Leverage Factor” shall equal 2. 
 “Market Disruption Event”, with respect to the Index or any Successor Index, shall mean any of the following events has occurred on any day as determined by the Calculation Agent: 
  

	 	(1)	a suspension, absence or material limitation of trading of stocks then constituting 20% or more of the level of the Index (or the relevant Successor Index) on the Relevant Exchanges
for such securities at any time during the one hour period preceding the close of the principal trading session on such Relevant Exchange; 

  

	 	(2)	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% or more of
the level of the Index (or the relevant Successor Index) at any time during the one hour period preceding the close of the principal trading session on such Relevant Exchange are materially inaccurate; 









	 	(3)	a suspension, absence or material limitation of trading on any major securities exchange for trading in futures or options contracts or exchange traded funds related to the Index
(or the relevant Successor Index) at any time during the one hour period preceding the close of the principal trading session on such exchange; or 

  

	 	(4)	a decision to permanently discontinue trading in the relevant futures or options contracts or exchange traded funds. 

 For the purpose of determining whether a Market Disruption Event exists at any time, if trading in a security included in the Index is materially
suspended or materially limited at that time, then the relevant percentage contribution of that security to the level of the Index shall be based on a comparison of: 
  

	 	(1)	the portion of the level of the Index attributable to that security relative to 

  

	 	(2)	the overall level of the Index, 

 in each case immediately before that
suspension or limitation. 
 For purposes 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)	limitations pursuant to the rules of any Relevant Exchange similar to NYSE Rule 80B (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 80B as determined by the Calculation Agent in its sole discretion) on trading during significant market fluctuations will constitute a suspension, absence or material limitation of
trading; 

  

	 	(3)	a suspension of trading in futures or options contracts on the Index by the primary securities market trading in such contracts by reason of (i) a price change exceeding limits
set by such exchange or market, (ii) an imbalance of orders relating to such contracts, or (iii) a disparity in bid and ask quotes relating to such contracts, will, in each such case, constitute a suspension, absence or material limitation
of trading in futures or options contracts related to the Index; and 

  

	 	(4)	a suspension, absence or material limitation of trading on any Relevant Exchange or on the primary market on which futures or options contracts related to the Index are traded will
not include any time when such market is itself closed for trading under ordinary circumstances. 








 “Maturity Date” shall mean May 6, 2009, unless that day is not a Business Day, in
which case the amount equal to the Payment at Maturity that would otherwise be due on the scheduled Maturity Date will instead be due on the next succeeding Business Day following such scheduled Maturity Date, with the same effect as if paid on the
scheduled Maturity Date; provided that if due to a non-Trading Day or a Market Disruption Event, the Valuation Date is postponed so that it falls less than three Business Days prior to the scheduled Maturity Date, the Maturity Date will be the third
Business Day following the Valuation Date, as postponed. 
 “Payment at Maturity”, as calculated by the Calculation Agent
for each $10 principal amount Security, shall equal: 
  

	 	•	 	 If the Index Return is positive, the lesser of: 


 (1) $10 + ($10 × Index Return × Leverage Factor); and 
 (2) $12.03 
  

	 	•	 	 If the Index Return is equal to or less than 0% and equal to or greater than -10%: $10 


  

	 	•	 	 If the Index Return is less than -10%: $10 + [$10 × (Index Return + 10%)]. 


 “Place of Payment” shall mean the place or places where the Payment at Maturity on the Securities is payable. 
 “Pricing Date” shall mean November 2, 2007. 
 “Relevant Exchange” for any security (or any combination thereof) then included in the Index or any Successor Index, shall mean the primary exchange, quotation system (which includes bulletin board
services) or other market of trading for such security. 
 “Securities” shall have the meaning set forth on the reverse of
this Security. 
 “Successor Index” shall have the meaning specified under “Discontinuation of the Index; Alteration
of Method of Calculation”. 
 “Trading Day” means a day, as determined by the Calculation Agent, on which trading is
generally conducted (i) on the Relevant Exchanges for securities included in the Index (or the relevant Successor Index) and (ii) the exchanges on which futures or options contracts related to the Index (or the relevant Successor Index)
are traded, other than a day on which trading on such Relevant Exchange or exchange on which such securities, futures or options contracts are traded is scheduled to close prior to its scheduled weekday closing time. 
 “Trustee” shall have the meaning set forth on the reverse of this Security. 
 “Valuation Date” shall mean May 1, 2009; provided, however, that if the scheduled Valuation Date is not a Trading
Day or if there is a Market Disruption Event on such day, the Valuation Date shall be postponed to the immediately succeeding Trading Day during which no Market Disruption Event shall have occurred or shall be continuing; provided,
however, that the Index Ending Level for the Valuation Date shall not be determined on a date later than the eighth 








 
scheduled Trading Day after the originally scheduled Valuation Date, and if such day is not a Trading Day, or if there is a Market Disruption Event on such
date, the Calculation Agent shall determine the Index Ending Level for the Valuation Date on such date in accordance with the formula for and method of calculating the Index Ending Level last in effect prior to commencement of the Market Disruption
Event (or prior to the non-Trading Day), using the Closing Price (or, if trading in the relevant securities has been materially suspended or materially limited, the Calculation Agent’s good faith estimate of the Closing Price that would have
prevailed but for such suspension or limitation or non-Trading Day) on such eighth scheduled Trading Day of each security most recently constituting the Index. 
 All terms used but not defined in this Security are used herein as defined in the Calculation Agency Agreement or the Indenture. 
 Calculation Agent 
 The Calculation Agent will determine, among other things, the Index Ending Level, the Index Return and
the Payment at Maturity. In addition, the Calculation Agent will determine whether there has been a Market Disruption Event or a discontinuation of the Index, and whether there has been a material change in the method of calculation of the Index.
All calculations, determinations or 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. 
 Discontinuation of the Index; Alteration of Method of Calculation 
 If the Index Sponsor discontinues publication of the Index and the Index Sponsor or another entity publishes a successor or substitute index that the Calculation Agent determines, in its sole discretion, to be
comparable to the discontinued Index (a “Successor Index”), then any Index Closing Level will be determined by reference to the level of such Successor Index at the close of trading on the Relevant Exchange or market for the Successor
Index on any Trading Day. Upon any selection by the Calculation Agent of a Successor Index, the Calculation Agent will cause written notice thereof to be promptly furnished to the Trustee, to the Company and to the Holders. 
 If the Index Sponsor discontinues publication of the Index, and such discontinuation is continuing on any Trading Day, and the Calculation Agent
determines, in its sole discretion, that no Successor Index is available at such time, or if the Calculation Agent has previously selected a Successor Index and publication of such Successor Index is discontinued, and such discontinuation is
continuing on any Trading Day, or if the Index Sponsor (or the publisher of any Successor Index) fails to calculate and publish an Index Closing Level for the Index (or any Successor Index) on any date when it would ordinarily do so in accordance
with its customary practice, then the Calculation Agent will determine the Index Closing Level for such Trading Day or such date. The Index Closing Level will be computed by the Calculation Agent in 








 
accordance with the formula for and method of calculating the Index or Successor Index, as applicable, last in effect on the date prior to such
discontinuation or failure to calculate or publish an Index Closing Level for the Index or Successor Index, as applicable, 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 on such date of each security most recently included in the Index or Successor Index, as
applicable. 
 If at any time the method of calculating the Index or a Successor Index, or the level thereof, is changed in a material
respect, or if the Index or a Successor Index is in any other way modified so that the Index or such Successor Index does not, in the opinion of the Calculation Agent, fairly represent the level of the Index or such Successor Index in the absence of
such changes or modifications, then 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 level of a stock index comparable to the Index or such Successor Index, as the case may be, as if such changes or modifications were not made, and the Calculation Agent will calculate the
Index Closing Level with reference to the Index or such Successor Index, as adjusted. Accordingly, if the method of calculating the Index or a Successor Index is modified so that the level of the Index or such Successor Index is a fraction of what
it would have been if there had been no such modification (e.g., due to a split in the Index), then the Calculation Agent will adjust its calculation of the Index or such Successor Index in order to arrive at a level of the Index or such
Successor Index as if there had been no such modification (e.g., as if such split had not occurred).
