 Index LeAding StockmarkEt Return Securities (Index LASERSSM) Based Upon the S&P 500® 
 Index Due January 27, 2010

  
 Citigroup Funding Inc., a Delaware corporation (hereinafter
referred to as the “Company”, which term includes any successor corporation under the Indenture herein referred to), for value received and on condition that this Note is not redeemed by the Company prior to January 27, 2010
(the “Stated Maturity Date”), hereby promises to pay to CEDE & CO., or its registered assigns, the Maturity Payment (as defined below), on the Stated Maturity Date. This Note will not bear interest, is not subject to any
sinking fund, is not subject to redemption at the option of the holder thereof prior to the Stated Maturity Date, and is not subject to the defeasance provisions of the Indenture. The payments on this Note are fully and unconditionally guaranteed by
Citigroup Inc., a Delaware corporation (the “Guarantor”). 
  
 Payment of the Maturity Payment with respect to this Note shall be made upon presentation and surrender of this Note at the corporate trust office of the Trustee in the Borough of Manhattan, The City and State of New
York, in such coin or currency of the United States as at the time of payment is legal tender for payment of public and private debts. 







 This Note is one of the series of 1,925,000 Index LeAding StockmarkEt Return Securities (Index
LASERSSM) Based Upon the S&P 500® Index (the “Index”) Due January 27, 2010 (the “Index LASERS”). 
  
 INTEREST 
  
 The Index LASERS do not bear interest. No payments on the Index LASERS will
be made until the Stated Maturity Date. 
  
 PAYMENT AT MATURITY 
  
 The Index LASERS will mature on
January 27, 2010. On the Stated Maturity Date, Holders of the Index LASERS will receive for each Index LASERS the Maturity Payment described below. 
  
 DETERMINATION OF THE MATURITY PAYMENT 
  
 The Maturity Payment for each Index LASERS equals the sum of the initial principal amount of $10 per Index LASERS plus the Index Return Amount.

  
 The “Index Return Amount” is calculated as
follows: 
  

	 	•	 	If the Index Return is positive, the Index Return Amount will equal the product of: 

  
 $10 * Upside Participation Rate * Index Return 
  

	 	•	 	If the Index Return is negative and 

  

	 	•	 	the value of the S&P 500 Index on any Index Business Day after January 24, 2006 up to and including the third Index Business Day before the Stated Maturity Date (whether
intra-day or at the close of trading on any Index Business Day) is less than or equal to 981.82, then the Index Return Amount will equal the product of: 

  
     $10 * Index Return 
  

	 	•	 	the value of the S&P 500 Index on any Index Business Day after January 24, 2006 up to and including the third Index Business Day before the Stated Maturity Date (whether
intra-day or at the close of trading on any Index Business Day) is not less than or equal to 981.82, then the Index Return Amount will be zero. 

  

	 	•	 	If the Index Return is zero, the Index Return Amount will be zero. 

  
 The “Index Return” equals: 
  
 Ending Value – Starting Value 
 Starting Value 
  

 2 








 The “Upside Participation Rate” is 110%. 
  
 The “Starting Value” is 1266.86, the closing value of the
Index on January 24, 2006. 
  
 The “Ending
Value” will be the closing value of the Index on the third Index Business Day before the Stated Maturity Date. 
  
 If no closing value of the Index is available on the third Index Business Day before the Stated Maturity Date because of a Market Disruption Event or
otherwise, the value of the Index for that Index Business Day, unless deferred by the calculation agent as described below, will be the arithmetic mean, as determined by the calculation agent, of the value of the Index obtained from as many dealers
in equity securities (which may include Citigroup Global Markets Inc. or any of the Company’s other affiliates), but not exceeding three such dealers, as will make such value available to the calculation agent. The determination of the value of
the Index by the calculation agent in the event of a Market Disruption Event may be deferred by the calculation agent for up to five consecutive Index Business Days on which a Market Disruption Event is occurring, but not past the Index Business Day
prior to the Stated Maturity Date. 
  
 An “Index Business
Day” means a day, as determined by the calculation agent, on which the Index or any Successor Index is calculated and published and on which securities comprising more than 80% of the value of the Index on such day are capable of being
traded on their relevant exchanges or markets during the one-half hour before the determination of the closing value of the Index. All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will be
conclusive for all purposes and binding on the Company, the Guarantor and the beneficial owners of the Index LASERS, absent manifest error. 
  
 A “Market Disruption Event” means, as determined by the calculation agent in its sole discretion, the occurrence or existence of any
suspension of or limitation imposed on trading (by reason of movements in price exceeding limits permitted by any relevant exchange or market or otherwise) of, or the unavailability, through a recognized system of public dissemination of transaction
information, for a period longer than two hours, or during the one-half hour period preceding the close of trading, on the applicable exchange or market, of accurate price, volume or related information in respect of (a) stocks which then
comprise 20% or more of the value of the Index or any Successor Index, (b) any options or futures contracts, or any options on such futures contracts relating to the Index or any Successor Index, or (c) any options or futures contracts
relating to stocks which then comprise 20% or more of the value of the Index or any Successor Index on any exchange or market if, in each case, in the determination of the calculation agent, any such suspension, limitation or unavailability is
material. 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 value of the Index will be based on a comparison of the portion of the value of the Index attributable to that security relative to the overall value of the Index, in each case immediately before that suspension or limitation.

 DISCONTINUANCE OF THE INDEX 
  
 If Standard & Poor’s (“S&P”) discontinues
publication of the Index or if it or another entity publishes a successor or substitute index that the calculation agent determines, in its sole discretion, to be comparable to the Index, then the value of the Index will be determined by reference
to the value of that index, which is referred to as a “Successor Index.” 
  
 Upon any selection by the calculation agent of a Successor Index, the calculation agent will cause notice to be furnished to the Company and the Trustee, who will provide notice of the selection of the Successor Index
to the registered holders of the Index LASERS. 
  
 If S&P
discontinues publication of the Index and a Successor Index is not selected by the calculation agent or is no longer published on any date of determination of the value of the Index, the value to be substituted for the Index for that date will be a
value computed by the calculation agent for that date in accordance with the procedures last used to calculate the Index prior to any such discontinuance. 
  
 If S&P discontinues publication of the Index prior to the determination of the Index Return Amount and the calculation agent determines that no
Successor Index is available at that time, then on each Index Business Day until the earlier to occur of (a) the determination of the Index Return Amount and (b) a determination by the calculation agent that a Successor Index is available,
the calculation agent will determine the value that is to be used in computing the value of the Index as described in the preceding paragraph. The calculation agent will cause notice of daily closing values to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general circulation). Notwithstanding these alternative arrangements, discontinuance of the publication of the Index may adversely affect trading in the Index LASERS. 

 
 If a Successor Index is selected or the calculation agent calculates a
value as a substitute for the Index as described above, the Successor Index or value will be substituted for the Index for all purposes, including for purposes of determining whether an Index Business Day or Market Disruption Event
occurs. Notwithstanding these alternative arrangements, discontinuance of the publication of the Index may adversely affect the market value of the Index LASERS. 
  
 All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will be
conclusive for all purposes and binding on the Company, the Guarantor and the beneficial owners of the Index LASERS, absent manifest error. 
  
 ALTERATION OF METHOD OF CALCULATION 
  
 If at any time the method of calculating the Index or any Successor Index is changed in any material respect, or if the Index or any Successor Index is in
any other way modified so that the value of the Index or the Successor Index does not, in the opinion of the calculation agent, fairly represent the value of that index had the changes or modifications not been made, then, from and after that time,
the calculation agent will, at the close of business in New York, New York, make those adjustments as, in the good faith judgment of the calculation agent, may be 
  

 4 








 necessary in order to arrive at a calculation of a value of a stock index comparable to the Index or the Successor Index
as if the changes or modifications had not been made, and calculate the value of the index with reference to the Index or the Successor Index. Accordingly, if the method of calculating the Index or the Successor Index is modified so that the value
of the Index or the Successor Index is a fraction or a multiple of what it would have been if it had not been modified, then the calculation agent will adjust that index in order to arrive at a value of the index as if it had not been modified.

  
 GENERAL 
  
 This Note is one of a duly authorized issue of debt securities (the
“Debt Securities”) of the Company, issued and to be issued in one or more series under a Senior Debt Indenture, dated as of June 1, 2005 (the “Indenture”), among the Company, the Guarantor and The Bank of New
York, as trustee (the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Guarantor, the Trustee and the holders of the Index LASERS, and the terms upon which the Index LASERS are, and are to be, authenticated and delivered. 
  
 In case an Event of Default with respect to the Index LASERS shall have occurred and be continuing, the amount declared due
and payable upon any acceleration of the Index LASERS permitted by the Indenture will be determined by the calculation agent and will be equal to, with respect to this Note, the Maturity Payment calculated as though the Stated Maturity Date of this
Note were the date of early repayment. In case of default at the Stated Maturity Date of this Note, this Note shall bear interest, payable upon demand of the beneficial owners of this Note in accordance with the terms of the Index LASERS, from and
after the Stated Maturity Date through the date when payment of such amount has been made or duly provided for, at the rate of 5.25% per annum on the unpaid amount due. 
  
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights
and obligations of the Company and the Guarantor and the rights of the holders of the Debt Securities of each series to be affected under the Indenture at any time by the Company, the Guarantor and a majority in aggregate principal amount of the
Debt Securities at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the holders of specified percentages in aggregate principal amount of the Debt Securities of any series at the time
Outstanding, on behalf of the holders of all Debt Securities of such series, to waive compliance by the Company and the Guarantor with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether
or not notation of such consent or waiver is made upon this Note. 
  
 The holder of this Note may not enforce such holder’s rights pursuant to the Indenture or the Index LASERS except as provided in the Indenture. No reference herein to the Indenture and no provision of this Note or of the Indenture
shall alter or impair the obligation of the 
  

 5 








 Company and the Guarantor to pay the Maturity Payment with respect to this Note, and to pay any interest on any overdue
amount thereof at the time, place and rate, and in the coin or currency, herein prescribed. 
  
 All terms used in this Note which are defined in the Indenture but not in this Note shall have the meanings assigned to them in the Indenture. 
  
 Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purposes.
