(c) The Notes shall be direct, senior, unsecured and unsubordinated obligations of the Issuer and shall rank pari passu, without any preference or priority of payment, between themselves and equally with all other senior, unsecured, unsubordinated obligations of the Issuer, from time to time outstanding. The 2011 Notes shall mature, unless previously redeemed or repurchased and cancelled, on July 18, 2011. The 2036 Notes shall mature, unless previously redeemed or repurchased and cancelled, on July 18, 2036.

(h) The Issuer initially appoints JPMorgan Chase Bank, N.A. (the “Calculation Agent”) to act as its calculation agent with respect to the Floating Rate Notes pursuant to a Calculation Agency Agreement, dated as of the date hereof, between the Issuer, the Guarantor and the Calculation Agent.

Section 1.02. AMOUNT

(a) The Trustee is authorized, upon receipt of Notes executed by an authorized officer of the Issuer for the purposes of the original issuance of the Notes, to authenticate, for the 2011 Notes, Notes in an aggregate principal amount initially not in excess of $750,000,000, for the 2036 Notes, Notes in an aggregate principal amount initially not in excess of $1,000,000,000, and for the Floating Rate Notes, Notes in an aggregate principal amount initially not in excess of $850,000,000 without any further action by the Issuer and to deliver the Global Securities in accordance with the written order of the Issuer.

Subject to the limitations set forth in the next sentence, the Issuer may, without the consent of any Holder, reopen any series of Notes and issue additional 2011 Notes, 2036 Notes or Floating Rate Notes, of like tenor (a “Further Issue”). Any Further Issue that utilizes the same ISIN, Common Code or “CUSIP” number as a Note already issued hereunder shall be effected only in a manner and under circumstances whereby the Further Issue is treated as a “qualified reopening” (within the meaning of U.S. Treasury Regulation Section 1.1275-2(k)(3), or any successor provision, all as in effect at the time of the Further Issue) of the issue of Notes having the shared ISIN, Common Code or “CUSIP” number, as the case may be. Any Further Issue shall initially be represented by a Global Security, in substantially the same form as set forth in Annexes A, B, C or D hereto, as the case may be. Any Further Issue shall be considered to be part of the relevant series of Notes, shall be fungible therewith shall rank equally and ratably therewith.

(c) The Issuer may not issue new Notes to replace securities that it has paid or delivered to the Trustee for cancellation.

Section 1.03. INTEREST

(a) Interest Rates.

(i) The 2011 Notes will bear interest from the Issue Date to Maturity at a fixed rate per annum equal to 6.20%.

(ii) The 2036 Notes will bear interest from the Issue Date to Maturity at a fixed rate per annum equal to 7.20%.

(iii) The Floating Rate Notes will bear interest from the Issue Date to Maturity at a floating rate to be reset quarterly on the first day of each Floating Rate Notes Interest Period (as defined below) that will be equal to LIBOR (as defined below) plus 0.61%, as determined by the Calculation Agent. The amount of interest on each Floating Rate Note for each day the Floating Rate Notes are outstanding (the “Daily Interest Amount”), will be calculated by dividing the interest rate in effect for that day by 360 and multiplying the result by the principal amount of such Floating Rate Note. The amount of interest to be paid on the Floating Rate Notes for each Floating Rate Notes Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Floating Rate Notes Interest Period. All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or 0.09876545) being rounded to 9.87655% (or 0.0987665)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). The interest rate on the Floating Rate Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

(b) Interest Payments.

(i) Interest on the 2011 Notes will be payable semi-annually in arrears on January 18 and July 18 of each year (each, a “2011 Notes Interest Payment Date”) commencing on January 18, 2007, to the persons in whose names the notes are registered at the close of business on the applicable preceding January 1 and July 1.

(ii) Interest on the 2036 Notes will be payable semi-annually in arrears on January 18 and July 18 of each year (each, a “2036 Notes Interest Payment Date” and, together with each 2011 Notes Interest Payment Date, a “Fixed Rate Notes Interest Payment Date”) commencing on January 18, 2007, to the persons in whose names the notes are registered at the close of business on the applicable preceding January 1 and July 1.

(iii) Interest on the Floating Rates Notes will be payable quarterly in arrears on January 18, April 18, July 18 and October 18 of each year (each, a “Floating Rate Notes Interest Payment Date” and, together with each Fixed Rate Notes Interest Payment Date an “Interest Payment Date”) with respect to the Floating Rate Notes Interest Period ending on and including the day prior to each Floating Rate Notes Interest Payment Date, commencing on October 18, 2006, to the persons in whose names the notes are registered at the close of business on the 15th calendar day preceding each Floating Rate Notes Payment Date.

(iv) The dates in this Section 1.03(b) with which reference is made to determine the Persons entitled to receive interest on the Notes of a series are collectively referred to as “Regular Record Dates”.

(v) If any Fixed Rate Notes Interest Payment Date, the Stated Maturity date or any earlier redemption or repayment date with respect to the applicable series of Fixed Rate Notes falls on a day which is not a Fixed Rate Notes Business Day, the related payment of principal, and any premium, and any accrued interest shall be postponed to the next succeeding Fixed Rate Notes Business Day; provided that interest on such payment shall not accrue during the period from and after such Fixed Rate Notes Interest Payment Date, Stated Maturity date, redemption or repayment date, as the case may be.

(vi) If any Floating Rate Notes Interest Payment Date, other than a Floating Rate Notes Interest Payment Date at maturity, would otherwise fall on a day which is not a Floating Rate Notes Business Day, it shall be postponed to the next day which is a Floating Rate Notes Business Day, except that, if that Floating Rate Notes Business Day falls in the next calendar month, then the Floating Rate Notes Interest Payment Date will be advanced to the immediately preceding Floating Rate Notes Business Day. If the maturity of the Floating Rate Notes falls on a day that is not a Floating Rate Notes Business Day, the required payment of principal, premium, if any, and interest shall be postponed to the next Floating Rate Notes Business Day, and no interest on such payment will accrue for the period from and after the maturity.

Section 1.04. REDEMPTION

(a) There shall be no sinking fund for the retirement of the Notes.

(b) Except as provided for in Section 1108 of the Base Indenture, neither the Issuer, the Guarantor nor the Holders shall be entitled to call any series of the Notes, except as provided below.

(i) At the option of the Issuer and without the consent of the Holders of the Fixed Rate Notes or the Trustee, the 2011 Notes and the 2036 Notes may be redeemed, in whole or in part, at any time on and after January 19, 2008, upon giving not less than 30 nor more than 60 days’ notice to the Holders of the Notes at a redemption price equal to the greater of (x) 100% of their aggregate principal amount plus accrued but unpaid interest to (but excluding) the date fixed for such redemption or (y) the Fixed Rate Notes Make-Whole Amount.

“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of five reference treasury dealer quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Further Issue” shall have the meaning as set forth in Section 1.02 hereof.

“Indenture” shall mean the Base Indenture, dated as of October 6, 2004, as supplemented and amended by this Third Supplemental Indenture.

If fewer than two rates are so provided, then LIBOR for the Floating Rate Notes Interest Period will be LIBOR in effect with respect to the immediately preceding Floating Rate Notes Interest Period. All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or 0.09876545) being rounded to 9.87655% (or 0.0987665)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

Annex B

Form of Reverse of Fixed Rate Security

This Security is one of a duly authorized issue of securities of the Issuer (the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of October 6, 2004, among the Issuer, Telecom Italia S.p.A., a joint stock company established under the laws of the Republic of Italy (herein called the “Guarantor”, which term includes any successor Person under the Indenture referred to herein), and JPMorgan Chase Bank, N.A., as Trustee (the “Trustee”, which term includes any other successor trustee under the Indenture), as supplemented by the Third Supplemental Indenture, dated as of July 18, 2006, among the Issuer, the Guarantor and the Trustee (as so supplemented, the “Indenture”), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Guarantor, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof and shall not be limited in aggregate principal amount.

The Issuer may from time to time, without the consent of the Holders, create and issue further securities having the same terms and conditions as the Securities in all respects (or in all respects except for the issue date, the first payment of interest thereon and/or issue price), so that such further issue shall be consolidated and form a single series with the outstanding Securities or upon such terms as the Issuer may determine at the time of their issue.

The Securities of this series are subject to redemption upon not less than 30 nor more than 60 days’ notice by mail, at any time on or after January 19, 2008 as a whole or in part, at the election of the Issuer, at the greater of (x) 100% of their aggregate principal amount plus accrued but unpaid interest to (but excluding) the date fixed for such redemption or (y) a Fixed Rate Note Make-Whole Amount.

The Securities may be redeemed at the option of the Issuer or the Guarantor, in whole but not in part, upon not less than 30 nor more than 60 days’ notice given as provided in the Indenture, at any time at a Redemption Price equal to the principal amount thereof plus accrued interest to the date fixed for redemption if as a result of any change in or amendment to the laws or any regulations or rulings promulgated thereunder of the jurisdiction (or of any political subdivision or taxing authority thereof or therein) in which the Issuer or the Guarantor is incorporated (or in the case of a successor Person to the Issuer or the Guarantor, of the jurisdiction in which such successor Person is organized or any political subdivision or taxing authority thereof or therein) or any change in the official application or interpretation of such laws, regulations or rulings, or any change in the official application or interpretation of, or any execution of or amendment to, any treaty or treaties affecting taxation to which such jurisdiction or such political subdivision or taxing authority (or such other jurisdiction or political subdivision or taxing authority) is a party, which change, execution or amendment becomes effective on or after July 18, 2006 (or, in the case of a successor Person to the Issuer or the Guarantor, the date on which such successor Person became such pursuant to the applicable provisions of the Indenture) (i) the Issuer or the Guarantor (or such successor Person) is or would be required to pay Additional Amounts with respect to the Securities or the Guarantees, respectively, on the next succeeding Fixed Rate Notes Interest Payment Date as set forth below

B-1

or in the Guarantee endorsed hereon or (ii) the Guarantor or any Subsidiary of the Guarantor is or would be required to deduct or withhold tax on any payment to the Issuer to enable the Issuer to make any payment of principal or interest in respect of the Securities and, in each case, the payment of such Additional Amounts in the case of (i) above or such deduction or withholding in the case of (ii) above cannot be avoided by the use of any reasonable measures available to the Issuer, the Guarantor or the Subsidiary.

The Securities may also be redeemed in whole but not in part upon not less than 30 nor more than 60 days’ notice given as provided in the Indenture at any time at a Redemption Price equal to the principal amount thereof plus accrued interest to the date fixed for redemption if the Person formed by a consolidation of the Issuer or the Guarantor or into which the Issuer or the Guarantor is merged or to which the Issuer or the Guarantor conveys, transfers or leases its properties and assets substantially as an entirety is required to pay a Holder additional amounts in respect of any tax, assessment or governmental charge imposed on any such Holder or required to be withheld or deducted from any payment to such Holder as a consequence of such consolidation, merger, conveyance, transfer or lease. However, the Securities may not be redeemed if the sole purpose of such a merger would be to permit such redemption.

Notice of redemption will be given by mail to Holders of Securities, not less than 30 nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance by the Issuer or the Guarantor with certain conditions set forth therein, which provisions apply to this Security.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

If any deduction or withholding for any present or future taxes or other governmental charges (including, for the avoidance of any doubt, any increase in the rate of the tax described in clause (6) below) of the Relevant Jurisdiction shall at any time be required by the Relevant Jurisdiction in respect of any amounts to be paid by the Issuer under the Securities, the Issuer will pay to the Holder of this Security, such additional amounts as may be necessary in order that the net amounts paid to such Holder of such Security shall be not less than the amounts specified in such Security to which such Holder is entitled; provided, however, that the Issuer shall not be required to make any payment of additional amounts for or on account of:

(1) any tax or other governmental charge which would not have been imposed but for the existence of any present or former connection between such Holder and the Relevant Jurisdiction (other than the mere holding of a Security and the receipt of payments thereon), including, without limitation, such Holder being or having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein;

B-2

(2) the application of European Directive 2003/48/EC of June 3, 2003, on the taxation of income from savings, as well as any equivalent measure adopted according to such directive;

(3) any tax or other governmental charge that would not have been imposed but for a failure to comply with any applicable certification, information, identification, documentation or other reporting requirements concerning the nationality, residence, identity or connection with the Relevant Jurisdiction if such compliance is required as a precondition to relief or exemption from such tax or other governmental charge (including without limitation a certification that such Holder is not resident in the Relevant Jurisdiction or an individual resident in a member state of the European Union);

(4) any tax or other governmental charge which would not have been imposed but for a change in law that becomes effective more than 30 days after a payment by the Issuer under the Securities becomes due and payable, or is duly provided for and notice thereof is duly published, whichever occurs later;

(5) any tax or other governmental charge required to be withheld by any Paying Agent from a payment on a Security, if such payment can be made without such deduction or withholding by any other Paying Agent;

(6) any tax or other governmental charge imposed pursuant to Italian Law No. 239 of April 1, 1996, as amended, on Holders not resident, for income tax purposes, in Italy and not resident, for income tax purposes, in the countries identified in the Decree of the Ministry of Finance of Italy of September 4, 1996, as amended or any superseding Decree replacing or modifying such list of countries; or

(7) any combination of items (1), (2), (3), (4), (5) and (6) above.

The foregoing provisions shall apply mutatis mutandis to any withholding or deduction for or on account of any present or future taxes or governmental charges of whatever nature of any jurisdiction in which any successor Person to the Issuer is organized, or any political subdivision or taxing authority thereof or therein. In addition, neither the Issuer nor the Guarantor shall have any obligation to pay Additional Amounts to a Holder that is a fiduciary or partnership or an entity that is not the sole beneficial owner of the payment of the principal or interest on a Security to the extent that the laws of the Relevant Jurisdiction require the payment to be included in the income of a beneficiary or settlor for tax purposes with respect to such fiduciary, a member of such partnership or the beneficial owner who would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Security.

Upon request, the Issuer shall provide the Trustee with documentation (which may consist of certified copies of such documentation) satisfactory to the Trustee evidencing the payment of Luxembourg taxes with respect to payment on the Securities. Copies of such documentation shall be made available to the Owners of the Securities or the Paying Agent, as applicable, upon request therefor.

B-3

The Issuer shall pay all stamp and other duties, if any, and all documentary stamp or similar taxes, if any, which may be imposed by The Grand Duchy of Luxembourg, or any other governmental entity or political subdivision therein or thereof or any taxing authority of or in any of the foregoing, with respect to the Indenture, the initial issuance of this Security, any transfer of this Security or payment orders relating to this Security. The Issuer shall not assert or claim any exemption available to it in respect of any stamp or other duties, or documentary stamp or similar taxes, which it has agreed to pay under the preceding sentence, if, after the assertion or claiming of such exemption, Holders or Owners of this Security would be liable for such duty or tax.

All references in this Security to principal, premium or interest in respect of any Security shall be deemed to mean and include all Additional Amounts, if any, payable in respect of such principal, premium or interest, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such express mention is not made.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the Guarantor and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer, the Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer or 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any proceeding with respect to the Indenture, the Guarantee endorsed hereon, this Security or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, and the Trustee shall not have received from the Holders of a majority in principal of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal (and premium, if any) or any interest on this Security on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed or to convert this security as provided in the Indenture.

B-4

The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Security Registrar duly executed by, the Holder hereof or his, her or its attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Issuer may require from the Holder hereof payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Guarantor, the Trustee and any agent of the Issuer, the Guarantor or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and none of the Issuer, the Guarantor, the Trustee nor any such agent shall be affected by notice to the contrary.

The Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York. For the avoidance of doubt the provisions of Articles 86 to 94-8 of the Luxembourg law on commercial companies of August 10, 1915, as amended, are excluded.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

In case of the failure of Telecom Italia Capital (the “Issuer”, which term includes any successor Person under such Indenture), punctually to make any such payment of principal, premium, if any, or interest or any sinking fund or analogous payment, the Guarantor hereby agrees to cause any such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such payment were made by the Issuer.

The Guarantor hereby further agrees, subject to the limitations and exceptions set forth below, that if any deduction or withholding for any present or future taxes or other governmental charges (including, for the avoidance of any doubt, any increase in the rate of the tax described in clause (f) below) of the Relevant Jurisdiction shall at any time be required by the Relevant Jurisdiction in respect of any amounts to be paid by the Guarantor under this Guarantee, then the Guarantor will pay to the Holder of a Security as additional interest such additional amounts as may be necessary in order that the net amounts paid to the Holder of such Security shall be not less than the amounts specified in such Security to which such Holder is entitled; provided, however, that the Guarantor shall not be required to make any payment of additional amounts for or on account of:

(b) the application of European Directive 2003/48/EC of June 3, 2003, on the taxation of income from savings, as well as any equivalent measure adopted according to such directive;

E-1

(c) any tax or other governmental charge that would not have been imposed but for a failure to comply with any applicable certification, information, identification, documentation or other reporting requirements concerning the nationality, residence, identity or connection with the Relevant Jurisdiction if such compliance is required as a precondition to relief or exemption from such tax or other governmental charge (including without limitation a certification that such Holder is not resident in the Relevant Jurisdiction or an individual resident in a member state of the European Union);

(d) any tax or other governmental charge which would not have been imposed but for a change in law that becomes effective more than 30 days after a payment by the Guarantor under this Guarantee becomes due and payable, or is duly provided for and notice thereof is duly published, whichever occurs later;

(e) any tax or other governmental charge required to be withheld by any Paying Agent from a payment on a Security, if such payment can be made without such deduction or withholding by any other Paying Agent;

The foregoing provisions shall apply mutatis mutandis to any withholding or deduction for or on account of any present or future taxes or governmental charges of whatever nature of any jurisdiction in which any successor Person to the Guarantor is organized, or any political subdivision or taxing authority thereof or therein.

The Guarantor hereby agrees that its obligations hereunder shall be as if it were principal debtor and not merely surety, and shall be absolute, full and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or such Indenture, any failure to enforce the provisions of such Security or such Indenture, or any waiver, modification or indulgence granted to the Issuer with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of the Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or increase any premium payable upon redemption thereof, or alter the Stated Maturity thereof or,

No reference herein to such Indenture and no provision of this Guarantee or of such Indenture shall alter or impair the guarantee of the Guarantor, which is absolute and unconditional, of the due and punctual payment of the principal of, premium, if any, and interest on, and any sinking fund or analogous payments with respect to, the Security upon which this Guarantee is endorsed.

The obligations of the Guarantor under this Guarantee shall, without any further act or thing being required to be done or to occur, extend to the obligations of any successor Person who is not the Guarantor arising in respect of the Securities by virtue of a substitution pursuant to the Indenture.

This Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication of such Security shall have been manually executed by or on behalf of the Trustee under such Indenture.

All terms used in this Guarantee which are defined in such Indenture shall have the meanings assigned to them in such Indenture.

The Guarantee shall be governed by and construed in accordance with the laws of the State of New York.

Claims against the Issuer and the Guarantor for payment of principal in respect of the Indenture shall be prescribed unless made within ten years from the date of payment of the relevant series of securities.
