 Reverse of Security 
 This Security is one of a duly authorized series of Securities of the Company designated as Buffered Principal at Risk Enhanced Participation Notes Linked to a Basket of Four Indices Due May 9, 2011 (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 Basket Ending Level and the Basket Return (including each Basket
Index 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 $1,000 principal amount note 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 Observation 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. 

 2 
  
  

 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 $1,000 and any whole multiples of $1,000. 
 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 

 3 
  
  

 
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. 
 “Basket” shall mean the basket of four indices to which the Securities are linked. The Basket consists of the Dow Jones EURO STOXX 50® Index (SX5E), the FTSE 100 Index® (UKX), the Nikkei 225SM Index (NKY) and the S&P®/ASX 200 Index (AS51). 
 “Basket Closing Level,” as calculated by the Calculation Agent, is calculated as follows: 
 Basket Starting Level x [1 + (the sum of (Basket Index Return * Index Weighting) for all Basket Indices)] 
 “Basket Ending Level,” as calculated by the Calculation Agent, is equal to the Basket Closing Level on the Observation Date. 

“Basket Index” refers to each of the Dow Jones EURO STOXX 50® Index (SX5E), the FTSE 100 Index® (UKX), the Nikkei 225SM Index (NKY) and the S&P®/ASX 200 Index (AS51). 
 “Basket Index Ending Level” is the Closing Level of the Basket Index on the Observation Date. 

 4 
  
  

 “Basket Index Return,” as calculated by the Calculation Agent, is calculated as follows
for each Basket Index: 
  

	
	        Basket Index Ending Level – Basket Index Starting
Level        
	Basket Index Starting Level

 “Basket Index Starting Level” for each of the four indices is as follows:

  

			
	 Dow Jones EURO STOXX 50® Index
 FTSE 100 Index®
 Nikkei 225SM Index
 S&P®/ASX 200 Index
	  	4445.59
6603.70
17669.83
6304.90

 “Basket Return”, as calculated by the Calculation Agent, is calculated as
follows: 
  

	
	        Basket Ending Level – Basket Starting Level        
	Basket Starting Level

 “Basket Starting Level” will be set to equal 100 on the Pricing Date. 

“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 Level” of a Basket Index on any Trading Day will generally equal the official Closing Level of the Basket Index, or any
Successor Basket Index thereto published following the regular official weekday close of trading for each such Basket Index on that Trading Day. 
 “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. 

 5 
  
  

 “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 Weightings” shall mean the weighting for the Basket Indices (each an “Index Weighting”). The Index Weightings of the
four Basket Indices are as follows: 
  

				
	 Dow Jones EURO STOXX 50® Index
 FTSE 100 Index®
 Nikkei 225SM Index
 S&P®/ASX 200 Index
	  	39.0
29.0
22.0
10.0	%

%

 “Market Disruption Event”, with respect to any of the Basket Indices (or any
Successor Basket Index), means: 
  

	 	•	 	 a suspension, absence or material limitation of trading of stocks then constituting 20% or more of the level of such Basket Index (or the relevant Successor Basket
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; 

  

	 	•	 	 a breakdown or failure in the price and trade reporting systems of the primary market of any Relevant Exchange as a result of which the reported trading prices for
stocks then constituting 20% or more of the level of such Basket Index (or the relevant Successor Basket Index) at any time during the one hour period preceding the close of the principal trading session on such Relevant Exchange are materially
inaccurate; 

  

	 	•	 	 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 such Basket Index (or the relevant Successor Basket Index) at any time during the one hour period preceding the close of the principal trading session on such exchange; or 

  

	 	•	 	 a decision to permanently discontinue trading in the relevant futures or options contracts or exchange traded funds; 

 in each case as determined by the Calculation Agent in its sole discretion. 
 For the purpose of determining whether a Market Disruption Event exists at any time, if trading in a security included in a Basket Index (or relevant Successor Basket Index) is materially suspended or materially
limited at that time, then the relevant percentage contribution of that security to the level of such Basket Index (or the relevant Successor Basket Index) shall be based on a comparison of: 

 6 
  
  

	 	•	 	 the portion of the level of such Basket Index (or the relevant Successor Basket Index) attributable to that security relative to 

  

	 	•	 	 the overall level of such Basket Index (or the relevant Successor Basket Index), 

 in each case immediately before that suspension or limitation. 
 For purposes of determining whether a
Market Disruption Event has occurred: 
  

	 	•	 	 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; 

  

	 	•	 	 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; 

  

	 	•	 	 a suspension of trading in futures or options contracts on a Basket Index (or the relevant Successor Basket Index) by the primary securities market trading in such
contracts by reason of: 

  

	 	•	 	 a price change exceeding limits set by such exchange or market, 

  

	 	•	 	 an imbalance of orders relating to such contracts, or 

  

	 	•	 	 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 such Basket Index (or the relevant Successor Basket Index); and 
  

	 	•	 	 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 a Basket
Index (or the relevant Successor Basket Index) are traded will not include any time when such market is itself closed for trading under ordinary circumstances. 

 7 
  
  

 “Maturity Date” shall mean May 9, 2011, 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 Observation 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 Observation Date, as postponed. 
 “Observation Date” shall mean May 4, 2011, provided
that if the Observation Date is not a Trading Day or if there is a Market Disruption Event on such day, with respect to a Basket Index, the Calculation Agent will: 
  

	 	•	 	 with respect to each Basket Index for which such day is a Trading Day and for which a Market Disruption Event has not occurred, determine the Closing
Level of such Basket Index for use in calculating the Basket Index Ending Level by reference to the Closing Level of such Basket Index on that Trading Day; and 

  

	 	•	 	 with respect to each Basket Index for which such day is not a Trading Day or for which a Market Disruption Event has occurred, determine the Closing
Level of such Basket Index for use in calculating the Basket Index Ending Level by reference to the Closing Level of such Basket Index on the next Trading Day for such Basket Index on which there is not a Market Disruption Event; provided,
however, if a Market Disruption Event with respect to such Basket Index occurs on each of the eight Trading Days following the originally scheduled Observation Date, then the Calculation Agent shall determine the Closing Level of such Basket
Index for use in calculating the Basket Index Ending Level in accordance with the formula for and method of calculating the closing index level of such Basket Index 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, its 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 included in the Basket Index. 

 “Participation Rate” shall be equal to 130.00%. 
 “Payment at Maturity”, as calculated by the
Calculation Agent for each $1,000 principal amount Security shall equal: 
  

	 	•	 	 If the Basket Ending Level is equal to or above the Basket Starting Level, $1,000 + [$1,000 x (Basket Return x Participation Rate)]. 

 

	 	•	 	 If the Basket Ending Level is below the Basket Starting Level by an amount equal to or less than the Protection Percentage, $1,000. 

 8 
  
  

	 	•	 	 If the Basket Ending Level is below the Basket Starting Level by more than the Protection Percentage, $1,000 + [($1,000 x (Basket Return + Protection Percentage)].

 “Place of Payment” shall mean the place or places where the Payment at Maturity on the Securities is
payable. 
 “Pricing Date” shall mean May 7, 2007. 
 “Protection Percentage” shall be equal to 20%. 
 “Relevant Exchange” for any security (or any combination thereof) then included in a Basket Index or any Successor Basket Index, means 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. 
 “Security” shall have the meaning set forth on the face of this Security. 
 “Successor Basket Index” shall have the meaning specified under “Discontinuance of a Basket Index; Alteration of Method of
Calculation” with respect to each Basket Index. 
 “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 Basket Index (or the relevant Successor Basket Index) and (ii) the exchanges on which futures or options contracts related to the Basket
Index (or the relevant Successor Basket 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. 
 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 Basket Closing Level on the Observation Date, including each Basket Index Return and each Basket Index Ending Level, the Basket Ending Level, the Basket Return and the payment at maturity, if any, on the
Securities. In addition, the Calculation Agent will determine whether there has been a Market Disruption Event or a discontinuation of any Basket Index (or the relevant Successor Basket Index) and whether there has been a material change in the
method of calculating any of the Basket Indices. 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 

 9 
  
  

 
may appoint a different Calculation Agent from time to time after the date of the original issue of the Securities without Holders’ consent and without
notifying Holders. 
 Discontinuation of a Basket Index; Alteration of Method of Calculation 
 Dow Jones EURO STOXX 50® Index 
 If STOXX Limited discontinues publication of the Dow Jones EURO STOXX 50® Index and STOXX Limited or another entity publishes a successor or substitute index that the Calculation Agent determines, in its sole discretion, to be comparable to the discontinued Dow Jones EURO STOXX 50® Index (a “Successor Basket Index”), then any
Basket Closing Level will be determined by reference to the level of such Successor Basket Index at the close of trading on the Relevant Exchange or market for the Successor Basket Index on the Observation Date. Upon any selection by the Calculation
Agent of a EURO STOXX 50® Index 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
STOXX Limited discontinues publication of the Index prior to, and such discontinuation is continuing on, the Observation Date, and the Calculation Agent determines, in its sole discretion, that no Successor Basket Index is available at such time, or
the Calculation Agent has previously selected a EURO STOXX 50® Successor Index and publication of such Successor Basket Index is discontinued prior to, and such discontinuation is continuing on, the Observation Date, or if STOXX Limited (or the publisher of any Successor Basket
Index) fails to calculate and publish a Closing Level for the Dow Jones EURO STOXX 50® Index (or any Successor Basket Index) on any date when it would ordinarily do so in accordance with its customary practice, then the Calculation Agent will determine the Closing Level for such date. The
Closing Level will be computed by the Calculation Agent in accordance with the formula for and method of calculating the Dow Jones EURO STOXX 50® Index or Successor Basket Index, as applicable, last in effect prior to such discontinuation or failure to calculate or publish a Closing Level for the
Dow Jones EURO STOXX 50® Index or Successor Basket
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 composing the Dow Jones EURO STOXX 50® Index or Successor Basket Index, as applicable. 
 If at any time the method of calculating the Dow Jones EURO STOXX 50® Index or a Successor Basket Index, or the level thereof, is changed in a material respect, or if the Dow Jones EURO STOXX 50® Index or a Successor Basket Index is in any other way modified so that the Dow Jones EURO STOXX 50® Index or such Successor Basket Index does not, in the opinion of the Calculation Agent,
fairly represent the level of the Dow Jones EURO STOXX 50® Index or such Successor Basket Index had such changes or modifications not been made, then the Calculation Agent will, at the close of business in New York City on each date on which the 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 Dow Jones EURO STOXX 50® Index or such Successor Basket Index, as the 

 10 
  
  

 
case may be, as if such changes or modifications had not been made, and the Calculation Agent will calculate the Closing Level with reference to the Dow
Jones EURO STOXX 50® Index or such Successor Basket
Index, as adjusted. Accordingly, if the method of calculating the Dow Jones EURO STOXX 50® Index or a Successor Basket Index is modified so that the level of the Dow Jones EURO STOXX 50® Index or such Successor Basket 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 Dow Jones EURO STOXX 50® Index or such Successor Basket Index in order to arrive at a level of the Dow Jones EURO STOXX 50® Index or such Successor Basket Index as if there had been no such modification (e.g., as if such split had not
occurred). 
 FTSE 100 Index® 
 If FTSE discontinues publication
of the FTSE 100 Index® and FTSE or another entity
publishes a successor or substitute index that the Calculation Agent determines, in its sole discretion, to be comparable to the discontinued FTSE 100 Index® (a “Successor Basket Index”), then any Basket Closing Level will be determined by reference to the level of such Successor Basket
Index at the close of trading on the Relevant Exchange or market for the Successor Basket Index on the Observation Date. Upon any selection by the Calculation Agent of a Successor Basket Index, the Calculation Agent will cause written notice thereof
to be promptly furnished to the Trustee, to the Company and to the Holders. 
 If FTSE discontinues publication of the FTSE 100 Index® prior to, and such discontinuation is continuing on,
the Observation Date, and the Calculation Agent determines, in its sole discretion, that no Successor Basket Index is available at such time, or the Calculation Agent has previously selected a Successor Basket Index and publication of such Successor
Basket Index is discontinued prior to, and such discontinuation is continuing on, the Observation Date, or if FTSE (or the publisher of any Successor Basket Index) fails to calculate and publish a Closing Level for the FTSE 100 Index® (or any Successor Basket Index) on any date when it
would ordinarily do so in accordance with its customary practice, then the Calculation Agent will determine the Closing Level for such date. The Closing Level will be computed by the Calculation Agent in accordance with the formula for and method of
calculating the FTSE 100 Index® or Successor Basket
Index, as applicable, last in effect prior to such discontinuation or failure to calculate or publish an Closing Level for the FTSE 100 Index® or Successor Basket 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 composing the FTSE 100 Index
or Successor Basket Index, as applicable. 
 If at any time the method of calculating the FTSE 100 Index® or a Successor Basket Index, or the level thereof, is changed in a material respect, or
if the FTSE 100 Index® or a Successor Basket Index
is in any other way modified so that the FTSE 100 Index® or such Successor Basket Index does not, in the opinion of the Calculation Agent, fairly represent the level of the FTSE 100 Index® or such Successor Basket Index had such changes or modifications not been made, then the Calculation Agent will, at the
close of business in New York City on 

 11 
  
  

 
each date on which the 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 FTSE 100 Index® or such FTSE Index, as the case may be, as if such changes or modifications had not been made, and the Calculation Agent will calculate the Closing Level with reference to the FTSE 100
Index® or such Successor Basket Index, as adjusted.
Accordingly, if the method of calculating the FTSE 100 Index® or a Successor Basket Index is modified so that the level of the FTSE 100 Index® or such Successor Basket 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 FTSE 100 Index® or
such Successor Basket Index in order to arrive at a level of the FTSE 100 Index® or such Successor Basket Index as if there had been no such modification (e.g., as if such split had not occurred). 
 Nikkei 225SM Index 
 If Nikkei
Inc. discontinues publication of the Nikkei 225SM Index and Nikkei Inc. or another entity publishes a successor or
substitute index that the Calculation Agent determines, in its sole discretion, to be comparable to the discontinued Nikkei 225SM Index (a “Successor Basket Index”), then any Nikkei 225SM Index Closing Level will be
determined by reference to the level of such Successor Basket Index at the close of trading on the Relevant Exchange or market for the Successor Index on the Observation Date. Upon any selection by the Calculation Agent of a Successor Basket Index,
the Calculation Agent will cause written notice thereof to be promptly furnished to the Trustee, to the Company and to the Holders. 
 If Nikkei Inc. discontinues publication of the Nikkei 225SM Index prior to, and such discontinuation is continuing on, the Observation Date, and the Calculation Agent determines, in its sole discretion, that
no Successor Basket Index is available at such time, or the Calculation Agent has previously selected a Successor Basket Index and publication of such Successor Basket Index is discontinued prior to, and such discontinuation is continuing on, the
Observation Date, or if Nikkei Inc. (or the publisher of any Successor Basket Index) fails to calculate and publish a Closing Level for the Nikkei 225SM Index (or any Successor Basket Index) on any date when it would ordinarily do so in accordance with its customary practice, then the Calculation Agent will determine the Closing Level for such date.
The Closing Level will be computed by the Calculation Agent in accordance with the formula for and method of calculating the Nikkei 225SM Index or Successor Basket Index, as applicable, last in effect prior to such discontinuation or failure to calculate or publish an Closing Level for the Nikkei 225SM Index or Successor Basket 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 composing the Nikkei 225SM Index or Successor Basket Index, as applicable. 
 If at any time the method of calculating the Nikkei 225SM Index or a Successor Basket Index, or the level thereof, is changed in a material respect, or if the Nikkei 225SM Index or a Successor Basket Index is in any other way modified so that the Nikkei 225SM Index or such Successor Basket Index does not, in the opinion of the Calculation Agent, fairly represent the 

 12 
  
  

 
level of the Nikkei 225SM Index or such Successor Basket Index had such changes or modifications not been made, then the Calculation Agent will, at the close of business in New York City on each date on which the 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 Nikkei 225SM Index or such Successor Basket Index, as the case may be, as if such changes or modifications had not been made, and the Calculation Agent will calculate the
Closing Level with reference to the Nikkei 225SM Index or such Successor Basket Index, as adjusted. Accordingly, if
the method of calculating the Nikkei 225SM Index or a Successor Basket Index is modified so that the level of the
Nikkei 225SM Index or such Successor Basket 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 Nikkei 225SM Index or such Successor Basket Index in order to arrive at a level of the Nikkei 225SM Index or
such Successor Basket Index as if there had been no such modification (e.g., as if such split had not occurred). 
 S&P®/ASX 200 Index 
 If Standard & Poor’s Australian Index Committee discontinues publication of the S&P®/ASX 200 Index and Standard & Poor’s Australian Index Committee or another entity publishes a successor or substitute index that the Calculation Agent determines, in its
sole discretion, to be comparable to the discontinued S&P®/ASX 200 Index (an “Successor Basket Index”), then any S&P®/ASX 200 Index Closing Level will be determined by reference to the level of such Successor Basket Index at the close of trading on the Relevant Exchange or market for the Successor
Basket Index on the Observation Date. Upon any selection by the Calculation Agent of a Successor Basket Index, the Calculation Agent will cause written notice thereof to be promptly furnished to the Trustee, to the Company and to the Holders.

 If Standard & Poor’s Australian Index Committee discontinues publication of the S&P®/ASX 200 Index prior to, and such discontinuation is continuing on, the Observation
Date, and the Calculation Agent determines, in its sole discretion, that no Successor Basket Index is available at such time, or the Calculation Agent has previously selected a Successor Basket Index and publication of such Successor Basket Index is
discontinued prior to, and such discontinuation is continuing on, the Observation Date, or if Standard & Poor’s Australian Index Committee (or the publisher of any Successor Index) fails to calculate and publish a Closing Level for the
S&P®/ASX 200 Index (or any Successor Basket
Index) on any date when it would ordinarily do so in accordance with its customary practice, then the Calculation Agent will determine the Closing Level for such date. The Closing Level will be computed by the Calculation Agent in accordance with
the formula for and method of calculating the S&P®/ASX 200 Index or Successor Basket Index, as applicable, last in effect prior to such discontinuation or failure to calculate or publish an Closing Level for the S&P®/ASX 200 Index or Successor Basket 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 composing the S&P®/ASX 200 Index or Successor Basket Index, as applicable.

 If at any time the method of calculating the S&P®/ASX 200 Index or a Successor Basket Index, or the level thereof, is changed in a
material respect, or if the S&P®/ASX 200 Index
or a Successor Basket Index is in any other way modified so that the S&P®/ASX 200 Index or such Successor Basket Index does not, in the opinion of the Calculation Agent, fairly represent the level of the S&P®/ASX 200 Index or such Successor Basket Index had such changes or modifications not been made, then the Calculation
Agent will, at the close of business in New York City on each date on which the 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 S&P®/ASX 200 Index or such Successor Basket Index, as the case may be, as if such changes or modifications had not been made, and the Calculation Agent will calculate the Closing Level with reference to the S&P®/ASX 200 Index or such Successor Basket Index, as
adjusted. Accordingly, if the method of calculating the S&P®/ASX 200 Index or a Successor Basket Index is modified so that the level of the S&P®/ASX 200 Index or such Successor Basket 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 S&P®/ASX 200 Index or such Successor Basket Index in order to arrive at a level of the S&P®/ASX 200 Index or such Successor Basket Index as if there had been no such modification (e.g., as if such split had not occurred).

 Exhibit 10.1 
 Summary of Performance Measures Established for the WebEx Executive Cash Bonus Plan 
 On
January 3, 2007, the Board of Directors of WebEx Communications, Inc. (the Company or WebEx) established the performance measures for the WebEx executive cash bonus plan, effective as of January 1, 2007. 
 The WebEx Executive Cash Bonus Plan (the “Plan”) is not set forth in a written agreement. The Plan covers WebEx’s chief executive officer,
its chief financial officer and certain other executive officers. 
 Each participant in the Plan will be assigned an annual target bonus.
Bonuses are paid on a quarterly basis, based on performance in the preceding quarter. The amount of the bonus paid each quarter is subject to approval by the Board’s Compensation Committee, and the amount that would otherwise be due under the
Plan may be modified or eliminated by the Board’s Compensation Committee. The bonus for the chief executive officer is within the discretion of the Board’s Compensation Committee. The bonus for the chief marketing officer is based on
specific marketing objectives recommended to the Board’s Compensation Committee by the chief executive officer. For other company officers, the Plan consists of two components: (1) 20% from the chief executive officer’s recommendation
based on individual contribution (“Individual Performance Portion”), and (2) 80% from a formula based on Company financial performance and other metrics (“Company Performance Portion”). The Company Performance Portion is
determined primarily by the Company’s achievement of an incremental quarterly revenue goal which is set by the Board’s Compensation Committee each quarter. The Company Performance Portion may be reduced for failure to achieve the revenue
goal and the bonus may be eliminated entirely if the revenue falls below a certain threshold. The Company Performance Portion may be increased for achieving incremental quarterly revenue above the goal, if such over-achievement of incremental
quarterly revenue also meets certain profitability criteria. The maximum bonus payable each quarter under the Company Performance Portion of the Plan is 200% of the target amount. Amounts otherwise due under the Company Performance Portion may also
be reduced or eliminated for failure to achieve certain profitability goals and may also be reduced by up to 20% for failing to achieve other special objectives set by the Board’s Compensation Committee each quarter. The Compensation Committee
set special objectives for the first quarter of 2007 based on service availability and customer retention. 
 Bonuses for vice presidents who
do not report directly to the chief executive officer are based partially on this Plan and partially on specified personal objectives or, in the case of sales vice presidents, achievement of sales quotas.
