CITIGROUP FUNDING INC., a corporation duly organized and existing under the laws of the State of Delaware (herein referred to as the “Company”), for value received hereby promises to pay CEDE & Co. or registered assigns (a) the Principal Amount or, in the case of an Indexed Principal Note, the Face Amount adjusted by reference to prices, changes in prices, or differences between prices, of securities, currencies, intangibles, goods, articles or commodities or by such other objective price, economic or other measures (an “Index”) as described on the face hereof or in the pricing supplement attached hereto or delivered herewith, in the Specified Currency on the Stated Maturity shown above or earlier if and to the extent so provided herein and (b) accrued interest on the Principal Amount then outstanding (or in the case of an Indexed Principal Note, the Face Amount, then outstanding) at the Interest Rate shown above from the Original Issue Date shown above or from the most recent date to which interest has been paid or duly provided for, semiannually in arrears (unless otherwise set forth herein or in the pricing supplement attached hereto or delivered herewith) on the Interest Payment Dates specified on the face of this Note or in the pricing supplement attached hereto or delivered herewith and at the Stated Maturity, until, in either case, the Principal Amount then outstanding or the Face Amount is paid or duly provided for in accordance with the terms hereof.  Unless otherwise specified herein or in the pricing supplement attached hereto or delivered herewith, interest on this Note, if any, will be computed on the basis of a 360-day year of twelve 30-day months or, in the case of an incomplete month, the number of days elapsed.

The interest so payable, and punctually paid or duly provided for, on each Interest Payment Date will, as provided in the Indenture referred to on the reverse hereof, be paid to the person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which, unless otherwise specified on the face of this Note or in the pricing supplement attached hereto or delivered herewith (and other than interest payable at Stated Maturity), shall be the date (whether or not a Business Day) fifteen calendar days immediately preceding such Interest Payment Date and, in the case of interest payable at Stated Maturity, shall be the Stated Maturity of this Note.  Notwithstanding the foregoing, if this Note is issued between a Regular Record Date and the related Interest Payment Date, the interest so payable for the period from the Original Issue Date to such Interest Payment Date shall be paid on the next succeeding Interest Payment Date to the Registered Holder hereof on the related Regular Record Date.  Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Registered Holder hereof on such Regular Record Date, and may be paid to the person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Registered Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

The Company and the Trustee acknowledge that the Company is a “participating entity,” as that term is defined in 12 CFR Section 370.2(g), in the debt guarantee program (the “Debt Guarantee Program”) established by the Federal Deposit Insurance Corporation (“FDIC”) under its Temporary Liquidity Guarantee Program (“TLGP”).  As a result, this debt is guaranteed under the FDIC TLGP and is backed by the full faith and credit of the United States.  The details of the FDIC guarantee are provided in the FDIC’s regulations, 12 CFR Part 370, and at the FDIC’s website, www.fdic.gov/tlgp .  The expiration date of the FDIC’s guarantee is the earlier of the maturity date of this debt or June 30, 2012.

The Bank of New York Mellon is hereby designated as the duly authorized representative of the holder for purposes of making claims and taking other permitted or required actions under the Debt Guarantee Program (the “Representative”).  Any holder may elect not to be represented by the Representative by providing written notice of such election to the Representative.

For purposes of this Note, “Business Day” means:  (i) with respect to any Registered Note, any day that is not a Saturday or Sunday and that, in The City of New York, is not a day on which banking institutions are authorized or obligated by law or executive order to close; (ii) with respect to Registered Notes having a specified currency other than U.S. dollars only, other than Registered Notes denominated in Euros, any day that, in the principal financial center (as defined below) of the country of the Specified Currency, is not a day on which banking institutions generally are authorized or obligated by law to close; (iii) with respect to Notes denominated in Euros, a day on which the Trans-European Automated Real-Time Gross Settlement Express Transfer (“TARGET”) System is open (a “TARGET Business Day”); and (iv) with respect to any determination by the exchange rate agent (as defined below) of an exchange rate pursuant to notes having a specified currency other than U.S. dollars, any such day on which banking institutions and foreign exchange markets settle payments in New York City and London (an “Exchange Rate Business Day”).

As used above, a “principal financial center” means the capital city of the country issuing the Specified Currency.  However, with respect to U.S. dollars, Australian dollars, Canadian dollars, and Swiss francs, the principal financial center shall be The City of New York, Sydney, Toronto, and Zurich, respectively.

If this Note is an Amortizing Note as shown on the face hereof or in the pricing supplement attached hereto or delivered herewith, a portion or all the principal amount of the Note is payable prior to Stated Maturity in accordance with a schedule, by application of a formula, or by reference to an Index (as described above).

If the Holder of this Note has a Survivor’s Option, as indicated above, to elect repayment of this Note prior to Stated Maturity in the event of the death of any beneficial owner hereof, then, pursuant to exercise of such Survivor’s Option, the Company will repay this Note (or applicable portion hereof) when properly tendered for repayment by or on behalf of the Person (the “Representative”) that has authority to act on behalf of the deceased beneficial owner hereof under the laws of the appropriate jurisdiction (including, without limitation, the personal representative, executor, surviving joint tenant or surviving tenant by the entirety of such deceased beneficial owner) at a price equal to the Amortized Face Amount (calculated as set forth below) payable hereunder with respect to such beneficial owner, plus accrued interest thereon to the date of such repayment; provided , however , that the Company may, in its sole discretion, limit to $2,500,000 (or the approximate equivalent thereof in other currencies) the aggregate principal amount of Notes of this series as to which exercises of the Survivor’s Option will be accepted in any calendar year (the “Annual Put Limitation”) and, in the event that the Annual Put Limitation is applied, limit to $250,000 (or the approximate equivalent thereof in other currencies) the aggregate principal amount of Notes (or portions thereof) as to which exercises of the Survivor’s Option will be accepted in such calendar year with respect to any individual deceased beneficial owner of Notes; and provided , further , that the Company will not make any principal payment pursuant to exercise of the Survivor’s Option in an amount that is less than $5,000 (or the approximate equivalent thereof in other currencies), and, in the event that the foregoing limitations would result in the partial repayment to any individual deceased beneficial owner of Notes, the principal amount owned by such deceased beneficial owner must not be less than $5,000 (or the approximate equivalent thereof in other currencies) as a result of such repayment, which is the minimum authorized denomination of the Notes.  This Note, or any portion hereof, if tendered pursuant to an exercise of the Survivor’s Option, may be withdrawn by a written request of the Holder hereof received by the Paying Agent prior to its repayment.

The Amortized Face Amount of this Note on any date shall be the amount equal to (i) the Issue Price set forth on the face hereof plus (ii) that portion of the difference between such Issue Price and the stated principal amount of such Note that has accrued by such date at (x) the Bond Yield to Maturity set forth on the face hereof or (y) if so specified, the Bond Yield to Call set forth on the face hereof (computed in each case in accordance with generally accepted United States bond yield computation principles), provided , however , that in no event shall the Amortized Face Amount of a Note exceed its stated principal amount.  The Bond Yield to Call listed on the face of this Note shall be computed on the basis of the first occurring Optional Redemption Date with respect to such Note and the amount payable on such Optional Redemption Date.  In the event that such Note is not redeemed on such first occurring Optional Redemption Date, the Bond Yield to Call with respect to such Note shall be recomputed on such Optional Redemption Date on the basis of the next occurring Optional Redemption Date and the amount payable on such Optional Redemption Date, and shall continue to be so recomputed on each succeeding Optional Redemption Date until the Note is so redeemed.

This Note (or any portion hereof), if tendered pursuant to a valid exercise of the Survivor’s Option, will be accepted promptly based on the order in which all such Notes (or any portion thereof) are tendered, unless the acceptance hereof would (i) contravene the Annual Put Limitation or (ii) result in the acceptance during the then current calendar year of an aggregate principal amount of Notes (or portions thereof) exceeding $250,000 (or the approximate equivalent thereof) with respect to any individual deceased beneficial owner.  If, as of the end of any calendar year, the Company has not imposed the Annual Put Limitation or the aggregate principal amount of Notes that have been accepted pursuant to exercise of the Survivor’s Option during such year has not exceeded the Annual Put Limitation for such year, any exercise of the Survivor’s Option with respect to this Note (or any portion hereof) not accepted during such calendar year because more than $250,000 (or the approximate equivalent thereof) aggregate principal amount of Notes (or portions thereof) was tendered with respect to the individual deceased beneficial owner hereof will be accepted in the order all such Notes were tendered, to the extent that any such exercise would not trigger the Annual Put Limitation, if any, for such calendar year.  This Note (or portion hereof), if accepted for repayment pursuant to exercise of the Survivor’s Option, will be repaid on the first Interest Payment Date that occurs twenty or more calendar days after the date of such acceptance.  If this Note (or any portion hereof) is tendered for repayment and is not accepted in any calendar year due to the application of the Annual Put Limitation, then this Note (or any such portion) will be deemed to be tendered in the following calendar year based on the order in which all such Notes (or any portion thereof) were originally tendered, unless this Note (or any such portion hereof) is withdrawn by the Holder.  In the event that this Note (or any portion hereof) tendered for repayment pursuant to valid exercise of the Survivor’s Option is not accepted, the Paying Agent will deliver a notice to the affected Representative by first-class mail to the broker or other entity that represents the deceased beneficial owner of this Note that states the reasons this Note (or such portion) has not been accepted for repayment.  If this Note is an Amortizing Note as shown on the face hereof or in the pricing supplement attached hereto or delivered herewith, a portion or all the principal amount of the Note is payable prior to Stated Maturity in accordance with a schedule, by application of a formula, or by reference to an Index (as described above).

Subject to the foregoing, in order for the Survivor’s Option to be validly exercised, the Paying Agent must receive (i) a written request for repayment signed by the Representative, and such signature must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc. or a commercial bank or trust company having an office or correspondent in the United States, (ii) tender of this Note (or applicable portion hereof), (iii) appropriate evidence satisfactory to the Company and the Paying Agent that (A) the Representative has authority to act on behalf of the applicable deceased beneficial owner hereof, (B) the death of such beneficial owner has occurred and (C) the deceased was a beneficial owner hereof at the time of death, and (iv) if applicable, a properly executed assignment or endorsement, and (v) if the Note is held by a nominee of the deceased beneficial owner, a certificate satisfactory to the Paying Agent from such nominee attesting to the beneficial ownership of such Note.  All questions as to the eligibility or validity of any exercise of the Survivor’s Option will be determined by the Company, in its sole discretion, which determination will be final and binding.

The principal hereof and any premium and interest hereon are payable by the Company in the Specified Currency shown above.  If the Specified Currency shown above is other than U.S. dollars, the Company will arrange to convert all payments in respect hereof into U.S. dollars in the manner described on the reverse hereof.  The Holder hereof may, if so indicated above, elect to receive all payments in respect hereof in the Specified Currency by delivery of a written notice to the Trustee not later than fifteen calendar days prior to the applicable payment date.  Such election will remain in effect until revoked by written notice to the Trustee received not later than fifteen calendar days prior to the applicable payment date.  If the Company determines that the Specified Currency is not available for making payments in respect hereof due to the imposition of exchange controls or other circumstances beyond the Company’s control or is no longer used by the government of the country issuing such currency or for the settlement of transactions by public institutions or within the international banking community, then the Holder hereof may not so elect to receive payments in the Specified Currency, and any such outstanding election shall be automatically suspended, and payments shall be in U.S. dollars, until the Company determines that the Specified Currency is again available for making such payments.

Payments of interest in U.S. dollars (other than interest payable at Stated Maturity) will be made by check mailed to the address of the Person entitled thereto as such address shall appear on the Register; provided that, if the Holder hereof is the Holder of U.S. $10,000,000 (or the equivalent thereof in a currency other than U.S. dollars determined as provided on the reverse hereof) or more in aggregate principal amount of Registered Notes of like tenor and term, such U.S. dollar interest payments will be made by wire transfer of immediately available funds, but only if appropriate wire transfer instructions have been received in writing by the Trustee not less than fifteen calendar days prior to the applicable Interest Payment Date.  Simultaneously with any election by the Holder hereof to receive payments in respect hereof in the Specified Currency (if other than U.S. dollars), such Holder shall provide appropriate wire transfer instructions to the Trustee and all such payments will be made by wire transfer of immediately available funds to an account maintained by the payee with a bank located outside the United States.  The principal hereof and any premium and interest hereon payable at Stated Maturity will be paid in immediately available funds upon surrender of this Note at the corporate trust office or agency of the Trustee located in the City and State of New York.

The payments due on this Note are fully and unconditionally guaranteed by Citigroup Inc. (the “Guarantor”).

REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF AND IN ANY PRICING SUPPLEMENT ATTACHED HERETO OR DELIVERED HEREWITH, AND SUCH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS THOUGH FULLY SET FORTH IN THIS PLACE.

IN WITNESS WHEREOF, the Company has caused this Note to be executed under its corporate seal.
