SCHEDULE 13D

This Amendment No. 6 (this “Amendment”) amends the statement on Schedule 13D, dated October 31, 2007, as subsequently amended (the “Schedule 13D”), filed by Telefónica, S.A., a corporation organized under the laws of the Kingdom of Spain (“Telefónica”), with respect to the ordinary shares, euro 0.55 par value per share, of Telecom Italia S.p.A. (the “Telecom Italia Shares”), a company incorporated under the laws of the Republic of Italy (“Telecom Italia”). Except as expressly provided, this Amendment does not modify any of the information previously reported in the Schedule 13D. Capitalized terms used in this Amendment without definition have the meanings ascribed to them in the Schedule 13D.

Introduction

As previously described in Amendment No. 2 and No. 3 to Schedule 13D (filed on November 23, 2009 and December 29, 2009 by Telefónica), the terms of SI’s exit were approved on November 26, 2009, and the SI Exit Transaction was concluded on December 22, 2009. In addition, as previously described in Amendment No. 4 to Schedule 13D (filed on January 26, 2010, by Telefónica), on January 11, 2010 Telco refinanced its existing financial indebtedness maturing through the New Refinancing Facility with the Senior Lenders.

As previously described in Amendment No.5 to Schedule 13 D (filed on March 12, 2012 by Telefónica) on February 29, 2012, the Existing Shareholders agreed to renew the Shareholders’ Agreement for 3 years, that is, until 28 February 2015, and undertook to take actions to ensure the refinancing of Telco’s financial indebtedness through appropriate financial instruments, contractual agreements and/or corporate transactions in proportion to their respective shareholdings of Telco. A copy of the Telco press release related to these events, dated February 29, 2012, was previously filed as Exhibit 26.

On May 31, 2012 the Existing Shareholders announced the completion of the transactions regarding the refinancing of the financial indebtedness of Telco maturing in 2012 (the “2012 Refinancing”).

As part of the 2012 Refinancing, Telco (a) executed a capital increase of euro 600 million, entirely subscribed by all the Existing Shareholders on a pro rata basis (the “Capital Increase”), (b) issued a euro 1,750 million bond, entirely subscribed by all the Existing Shareholders on a pro rata basis, and (c) entered into a euro 1,050 million loan agreement (the “2012 Refinancing Facility”) with Société Générale, UniCredit Corporate Banking S.p.A., HSBC Bank plc, Intesa Sanpaolo and Mediobanca, as lenders (collectively, the “2012 Lenders”). The 2012 Refinancing Facility matures on November 27, 2013 and is guaranteed by a pledge (the “2012 Pledge”) in favor of the 2012 Lenders over 1,730,000,000 Telecom Italia Shares held by Telco (as such number of Telecom Italia Shares may vary from time to time also in accordance with the 2012 Refinancing Facility (the “2012 Pledged Shares”).

In connection with the Capital Increase, the Existing Shareholders amended article 5 of Telco’s by-laws, previously filed on Schedule 13D as Exhibit 13. An un-official translation of the amendments to article 5 of Telco’s by-laws is filed as Exhibit 27 hereto.

The funds received by Telco under the 2012 Refinancing have been used to repay the January 2010 New Refinancing Facility and the €1,300 million bonds previously issued by Telco and subscribed by Existing Shareholders, and will be used to repay the remaining banking debt of €860 million maturing between June and October 2012.

3

Pursuant to the terms of the 2012 Refinancing Facility, on May 31, 2012, the Existing Shareholders and the 2012 Lenders, entered into a new separate option agreement (the “2012 Pledged Shares Option Agreement”) pursuant to which the parties (i) terminated the Pledged Shares Option Agreement, entered into in January 2010; and (ii) established the terms and conditions that would govern the Existing Shareholders’ option to acquire the 2012 Pledged Shares from the 2012 Lenders (the “2012 Call Option”) in the event that the 2012 Lenders enforce the 2012 Pledge. Copies of the 2012 Pledged Shares Option Agreement and the Telco press releases announcing the events described above, dated May 3, 2012 and May 31, 2012, are filed as Exhibit 28, Exhibit 29 and Exhibit 30 hereto, respectively.

Items 6 and 7 of the Schedule 13D are hereby amended and supplemented to add the following:

Item 6. Contracts, Agreements, Understandings or Relationships with Respect to Securities of the Issuer.

2012 PLEDGED SHARES OPTION AGREEMENT

The description of the 2012 Pledged Shares Option Agreement in the Introduction to this Amendment No. 6 is incorporated herein by reference.

Pursuant to the 2012 Option Agreement, UniCredit S.p.A. (in its capacity as facility agent under the 2012 Refinancing Facility (the “Facility Agent”) will provide written notice to the Existing Shareholders of any enforcement of the 2012 Pledge under the 2012 Refinancing Facility (the “Enforcement Notice”). Together with the Enforcement Notice, the Facility Agent will also deliver to the Existing Shareholders a written notice (the “Calculation Notice”) stating (i) the aggregate amount outstanding under the 2012 Refinancing Facility plus interest accrued and to accrue thereunder and any other costs and expenses, including enforcement costs under the 2012 Refinancing Facility; (ii) the price at which the 2012 Lenders are entitled to acquire the 2012 Pledged Shares by enforcing the 2012 (the “Enforcement Price”), and (iii) the number of Pledged Shares that the 2012 Lenders would be entitled to appropriate by virtue of the enforcement of the 2012 Pledge (the “Appropriation Shares”).

Each Existing Shareholder is entitled to acquire from the 2012 Lenders the Appropriation Shares at a price per Appropriation Share equal to the higher of (i) the aggregate amount outstanding plus interest accrued and to accrue thereunder and any other costs and expenses, including enforcement costs, under the 2012 Refinancing Facility, divided by the aggregate number of the Appropriation Shares, and (ii) the Enforcement Price (in either case, the “Purchase Price”).

The 2012 Call Option will be validly exercised only if it is exercised for the exact amount of Appropriation Shares, provided, however, that if there is a discrepancy in the aggregate number of Appropriation Shares reported on the Exercise Notice due to clerical error, the relevant Existing Shareholders are entitled to cure, within one business day, such clerical error. The 2012 Call Option is exercised by means of delivery to the Facility Agent, and the other Existing Shareholders, of a written notice (the “Exercise Notice”), no later than five business days after receipt of the Calculation Notice, stating (i) its unconditional and irrevocable offer to purchase from the 2012 Lenders all or part of the Appropriation Shares at a price per share equal to the Purchase Price, and (ii) that the Exercise Notice complies with the shareholders agreement with respect to Telco then in force among the Existing Shareholders at that time. An Existing shareholder that delivers a valid Exercise Notice is referred to as an “Exercising Shareholder.”

If the 2012 Call Option is not validly exercised and, therefore, the Existing Shareholders do not acquire the Appropriation Shares, any Existing Shareholder, who refuses to make available to Telco in proportion to its shareholding in Telco the fund necessary to avoid or cure a default under the 2012 Refinancing Facility within the timeframe necessary to avoid the enforcement of the 2012 Pledge, by means of a transaction in compliance with the terms of the 2012 Shareholders Agreement (such Existing Shareholder, a “Dissenting Shareholder”), will be subject to a lock-up period for a period of six months from receipt of the Calculation Notice (the “Lock-up Period”).

4

During the Lock-up Period, each Dissenting Shareholder agrees not to sell, transfer, exchange either by way of a spot or forward contract or by any other derivative instruments or arrangements of any kind having a similar effect, any shares, convertible instrument or other equity or quasi-equity instruments of Telecom Italia (any such activity, a “Share Disposal”), provided, however, that such undertaking shall not apply (i) to Mediobanca and Intesa Sanpaolo when appropriating, buying or selling or otherwise transferring securities and other rights in the context of the enforcement of the 2012 Pledge, and (ii) to Mediobanca, Intesa Sanpaolo and Generali when appropriating, buying or selling or otherwise transferring securities and other rights in the context of the ordinary course of their trading activities. Nothing in the 2012 Option Agreement shall constitute or be interpreted as a restriction, impediment or limitation whatsoever to the right of the Existing Shareholders, whether a Dissenting Shareholder or not, to purchase or appropriate, either by way of a spot or forward contract or by any other derivative instruments or arrangements of any kind having a similar effect, any shares, convertible instrument or other equity or quasi-equity instruments of Telecom Italia at any time (any such activity, a “Share Acquisition”).

The Existing Shareholders further agreed that, during the Lock-up Period, following any enforcement of the 2012 Pledge, they will: (i) use their reasonable efforts to make Share Acquisitions (if any) from the 2012 Lenders in priority to any other market counterparty; and (ii) refrain from any trading activity or the making of any intentional, specific, negative communication (outside of the normal periodic or customary corporate communications of such entity) to either financial market counterparties or the press with respect to Telecom Italia Shares, which would adversely affect any Share Disposal by the 2012 Lenders in the context of an enforcement of the 2012 Pledge.

The foregoing summary of certain material provisions of the 2012 Pledged Shares Option Agreement does not purport to be a full and complete description of such document and is entirely qualified by reference to the full text of such document attached as Exhibit 27 hereto.

Dear Sirs,

Following to our conversations, please find attached herebelow our agreement and understanding in relation to the following:

This option agreement (the “Agreement”) is entered into

BY AND BETWEEN

Ÿ (Intesa Sanpaolo, Mediobanca, UniCredit, SG and HSBC hereinafter collectively referred to as the “Lenders”);

AND

Ÿ (TE, AG, IS and MB hereinafter collectively referred to as the “Shareholders”); (the “Parties”).

BETWEEN THE PARTIES IT IS AGREED as follows:

1.1 The Facility Agent (as defined below) undertakes to copy the Shareholders in any of the communications to be given to the Borrower in relation to Clause 19.13 (Acceleration) of the facility agreement (the “New Banking Facility Agreement”) entered into on 28^th May 2012 between inter alios the Lenders, as lenders, Telco S.p.A., as borrower, and UniCredit, also as facility agent (the “Facility Agent”).

1.2 Without prejudice to 1.1 above, should the Lenders decide to enforce the share pledge created over Telecom Italia S.p.A. ordinary shares pursuant to the provision of the pledge agreement to be entered into pursuant to the New Banking Facility Agreement (the “Share Pledge” and the “Share Pledge Agreement” respectively) (a form of which is attached hereto as Schedule 1) following an acceleration pursuant to and in accordance with Clause 19.13 (Acceleration) of the New Banking Facility Agreement, the following shall apply.

1.2.1 The Facility Agent shall copy each of the Shareholders in the notice enforcing the Share Pledge to be given to Telco S.p.A. pursuant to Clause 6.1 (Escussione del pegno) of the Share Pledge Agreement (the “Enforcement Notice”). Together with the Enforcement Notice or as soon as possible thereafter when the relevant information become available, the Facility Agent will also deliver to the Shareholders a calculation notice (the “Calculation Notice”) stating (i) the aggregate amount outstanding under the New Banking Facility Agreement plus interest accrued and to accrue thereunder and all other costs and expenses, including enforcement costs, up to the Transfer Date (as defined below); (ii) the price at which the Lenders can appropriate the pledged shares pursuant to Clause 6.3 (Determinazione del valore dell’Oggetto del Pegno e delle Obbligazioni Garantite) of the Share Pledge Agreement; and consequently (iii) the number of pledged shares that the Lenders may have the right to appropriate pursuant to the Share Pledge Agreement (the “Appropriation Shares”). It is agreed and understood that, if Clause 6.3(i)(c) and/or Clause 6.3(ii)(c) of the Share Pledge Agreement apply, the Calculation Notice shall be sent after the Facility Agent having obtained the appraisal referred to thereunder. If notwithstanding the good faith efforts of the Facility Agent no appraisal is obtained within 20 Business Days from the Enforcement Notice, the Shareholders shall no longer have any right to purchase the Appropriation Shares under this Agreement and the Lenders shall have the right to enforce the Share Pledge at their discretion, provided in such case that upon enforcement of the pledge in accordance with the Share Pledge Agreement the Lenders shall ensure, to the maximum extent allowed by applicable laws, that the Shareholders are allowed to participate, part passu with any other potential acquirer, in any sale process of the Appropriation Shares.

1.2.2 Each Shareholder shall be entitled to call and acquire from the Lenders (the “Right to Call”) the Appropriation Shares at the terms and conditions referred to herein and at a price per Appropriation Share (the “Purchase Price”) equal to the higher of (i) the price indicated in Clause 1.2.1 (ii) above, and (ii) the amount indicated in Clause 1.2.1 (i) above divided by the aggregate total number of the Appropriation Shares. The Facility Agent shall include the Purchase Price in the Calculation Notice.

1.2.4 The Exercise Notices shall be served upon UniCredit in its capacity as Facility Agent (or to any of its successors pursuant to the provisions of Clause 20.13 (Resignation of the Facility Agent) of the New Banking Facility Agreement), copying therein all the other Shareholders.

1.2.5 The Exercise Notices shall be valid and effective only if and to the extent they contain in aggregate offers to purchase the exact amount of the Appropriation Shares. If, instead, the Exercise Notices contain in aggregate offers to purchase a number of Appropriation Shares which is greater or lower than the number of Appropriation Shares, then, the Exercise Notices shall be deemed ineffective and the Shareholders shall no longer have any right to purchase the Appropriation Shares under this Agreement and the Lenders shall have the right to enforce the Share Pledge at their discretion. Provided further that, in the event the Exercise Notice(s) contain(s) in aggregate offers to purchase not the exact amount of the Appropriation Shares, the Facility Agent shall allow the Shareholders who have delivered valid Exercise Notice(s) 1 Business Day to cure the mistake by sending a further joint notice signed by all Shareholders that have delivered the Exercise Notice, stating the exact allocation of Appropriation Shares among the Shareholders.

1.2.6 The Shareholders acknowledge that the Facility Agent shall:

1.2.7 If the conditions under Clauses 1.2.5 and 1.2.6 above are satisfied, the Lenders shall appropriate the Appropriation Shares at a price per share equal to the Purchase Price under the Share Pledge Agreement on the 8^th Business Days from the date of the Calculation Notice and shall then sell and transfer on the same day (the “Transfer Date”) all the Appropriation Shares to the Exercising Shareholders as per the indications received in the Exercise Notices, provided that the transfer of all Appropriation Shares shall occur simultaneously and be conditional upon (i) receipt of a legal opinion issued by reputable legal counsel (at the request of any Exercising Shareholder) confirming valid delivery of the Exercise Notice based on the Shareholders Agreement, validity and enforceability of the relevant transfer deed, no conflict with applicable law and capacity and authority of the Exercising Shareholder(s), and (ii) receipt in full of the Purchase Price multiplied by the number of the Appropriation Shares. If for any reason whatsoever (including for the avoidance of doubt, any order of authority, attachment, seizure or precautionary measure) appropriation under the Share Pledge Agreement or transfer to the Exercising Shareholders cannot take place, then the Exercise Notices shall be deemed ineffective and the Shareholders shall no longer have any right to purchase the Appropriation Shares under this Agreement and the Lenders shall have the right to enforce the Share Pledge at their discretion, provided however in such case that (a) should the relevant order of authority, attachment, seizure, precautionary measure consist in an impediment to enforce the pledge (and consequently appropriation and transfer of the Appropriation Shares under this Agreement) (i) should it be removed or cured within 60 days, then the Lenders shall remain bound to this Agreement and shall deliver to the Shareholders a new Enforcement Notice and a new Calculation Notice and each Shareholder shall be entitled to exercised its Right to Call by delivering its Exercise Notice in accordance with this Agreement, (ii) should it NOT be removed or cured within 60 days, then the Lenders shall ensure, to the maximum extent allowed by applicable laws, that the Shareholders are allowed to participate, pari passu with any other potential acquirer, in any subsequent sale process of the Appropriation Shares provided that if the relevant order of authority, attachment, seizure or precautionary measure described above has been procured by a Shareholder who is also a Dissenting Party (as defined below), then the provisions of Clause 1.2.18 shall apply (save that the relevant period will commence from the end of the relevant authority, attachment, seizure or precautionary measure); and (b) should the relevant order of authority, attachment, seizure, precautionary measure impede appropriation and/or transfer of the Appropriation Shares under this Agreement but NOT enforcement of the pledge through other means, then the Exercise Notices shall be deemed ineffective and the Shareholders shall no longer have any right to purchase the Appropriation Shares under this Agreement and the Lenders shall have the right to enforce the Share Pledge at their discretion but the Lenders shall ensure, to the maximum extent allowed by applicable laws, that the Shareholders are allowed to participate, pari passu with any other potential acquirer, in any subsequent sale process of the Appropriation Shares provided, that if the relevant order of authority, attachment, seizure or precautionary measure described above has been procured by a Shareholder who is also a Dissenting Party, then the provisions of Clause 1.2.18 shall apply (save that the relevant period will commence from the end of the relevant authority, attachment, seizure or precautionary measure).

In the event an Exercising Shareholder is also a Lender and the transfer of the Appropriation Shares is to occur in respect of all Exercising Shareholders in accordance with this Clause 1.2.7, then such Lender / Exercising Shareholder (a) shall only purchase a number of Appropriation Shares equal to the positive difference between (i) the number of Appropriation Shares for which it has delivered a valid Exercise Notice; and (ii) the number of Appropriation Shares corresponding to its quota in the Facility Agreement; or (b) shall only sell a number of Appropriation Shares equal to the positive difference between (i) the number of Appropriation Shares corresponding to its quota in the Facility Agreement; and (ii) the number of Appropriation Shares for which it has delivered a valid Exercise Notice.

For the purpose of this Agreement “Dissenting Shareholder” means a Shareholder that refuses to make available to Telco in proportion to its shareholding in Telco, through a modality complying with the relevant terms of the Shareholders Agreement, the fund necessary to Telco to avoid or cure the default under the New Banking Facility Agreement within the timeframe necessary to avoid the enforcement of the Shares Pledge Agreement.

1.2.8 If, as a result of the procedure set out in paragraphs 1.2.2 to 1.2.6 above, the Lenders have not received valid and effective Exercise Notices for all and no more or no less than the Appropriation Shares, the Shareholders shall no longer have any right to purchase the Appropriation Shares under this Agreement and the Lenders shall have the right to enforce the Share Pledge at their discretion.

1.2.9 Any obligation assumed by a Shareholder under this Agreement or the Exercise Notice shall be assumed on a several basis (senza vincolo di solidarietà) with the other Shareholders. It remains understood and agreed that if on the Transfer Date any of Exercising Shareholder(s) does (do) not pay the purchase price pursuant to the relevant Exercise Notice, then the Lenders shall have no obligation to transfer the Appropriation Shares to that or to any other Exercising Shareholder(s), the Exercise Notices shall be deemed ineffective, the Shareholders shall no longer have any right to purchase the Appropriation Shares under this Agreement and the Lenders shall have the right to enforce the Share Pledge at their discretion, provided that the Facility Agent shall allow the Shareholder(s) who have/has not paid the purchase price 1 Business Day to cure its default and shall allow the Shareholder(s) to purchase their corresponding Appropriation Shares, in which case all transfers of Appropriation Shares shall take place one Business Day after the intended Transfer Date and after full payment for all Appropriation Shares has been received in full.

1.2.10 The obligations assumed by the Lenders under this Agreement shall be assumed by each Lender severally from the other Lender (senza vincolo di solidarietà) in proportion to each respective loans and commitments under the New Banking Facility Agreement at the time of the Transfer Date.

1.2.11 For the avoidance of doubt (as between the Shareholders only) (i) any sale and purchase of Appropriation Shares made pursuant to this Agreement shall be deemed to be permitted under the Shareholders’ Agreement and each Shareholder commits to the other Shareholders to take any step and carry out all actions required to give full implementation to the rights and obligations set out in this Agreement and (ii) any reference in the Shareholders Agreement to the New Refinancing Facility must be interpreted as a reference to the New Banking Facility Agreement.

1.2.12 The Parties agree that, for the sake of completeness, this Agreement shall be disclosed and made public in accordance to applicable laws.

1.2.14 Each Exercising Shareholder, severally and not jointly and pro-quota in proportion to the percentage of the Appropriation Shares acquired, further undertakes to indemnify and keep harmless each Lender and the Facility Agent and their respective directors and employees (each an “Indemnified Party”), from any prejudices, expenses and damages or liabilities incurred or suffered as a result of an action or lawsuit or claim brought by Telco S.p.A., any of the Shareholders and/or any third party in connection with the delivery and transfer of the Appropriation Shares pursuant to the Exercise Notices and the appropriation of the Appropriation Shares pursuant to Clause 1.2.7. To this purpose (i) the Indemnified Party shall deliver to the Exercising Shareholders notice of the relevant action, claim or lawsuit, specifying reasonable details thereto, (ii) in the event of a claim brought by a third party, before making any payment or settlement, the Indemnified Party shall consult in good faith with the Exercising Shareholders for at least 10 Business Days, including taking advice from reputable international legal counsel, provided that if the payment is to be made earlier than 10 Business Days the consultation period shall be shortened accordingly, (iii) after the Indemnified Party having fulfilled its obligations under (i) and (ii) above, payment of the indemnity hereunder shall be made 1 Business Day prior to the date on which the relevant Indemnified Party declares that it is under an obligation to make a payment or post a collateral in favor of a third party, without raising any objection (solve et repete), (iv) the Indemnified Party shall keep informed the Exercising Shareholders of the relevant action, lawsuit or claim and will consult and cooperate in good faith with the relevant Exercising Shareholders in pursuing any legal defense, against said action, lawsuit or claim, and (v) after payment by the Exercising Shareholders the Indemnified Party shall return to the relevant Exercising Shareholders any money paid by such Exercising Shareholders and recovered by the Indemnified Party from the third party or released from a collateral.

The Parties agree that (x) the above provisions will only apply to any indemnification which has an overall aggregate amount not exceeding Euro 260 million, while (y) in the event of an indemnification for an overall aggregate amount exceeding Euro 260 million the above provisions (including the “solve and repete” principle) would still apply, but no payment shall be demanded by the Indemnified Party unless such Indemnified Party has received a judgment or order of an authority (even if not final and conclusive) ordering it to pay such third party claim or requiring it to post a collateral.

Without prejudice to the solve et repete provision set forth above, no indemnity shall be payable to an Indemnified Party under this Clause 1.2.14 in relation to prejudices, expenses and damages or liabilities incurred or suffered as a result of such Indemnified Party gross negligence or willful misconduct (dolo o colpa grave), provided for the sake of clarity that the solve et repete will only apply to the extent the legal advice under (ii) above has been obtained.

If an Exercising Shareholder who is under an obligation to indemnify pursuant to this Clause 1.2.14 is also an Indemnified Party, then its indemnity obligation as Exercising Shareholder will be extinguished by way of confusione (pursuant to Article 1253 of the Civil Code) for an amount equal to the amount that it is entitled to receive as Indemnified Party.

1.2.15 The Parties acknowledge and agree that obligations under this Agreement are undertaken by each Party also by way of alea, pursuant to article 1469 of the Italian Civil Code.

1.2.16 The Parties acknowledge and agree that in case of a transfer or assignment from an Existing Lender to a New Lender pursuant to and in accordance with Clause 26.2 (Assignments and transfers by Lenders) of the New Banking Facility Agreement, the transferring Lender shall procure that the New Lender assumes all rights and obligations of the transferring Lender under this Agreement, by executing a letter of accession to this Agreement concurrently with the assignment or transfer pursuant to the New Banking Facility Agreement. The Parties grant the consent to such assumption of rights and obligation by the New Lender pursuant to article 1406 of the Italian Civil Code, with release pursuant to Article 1408 of the Italian Civil Code of the transferring Lender with respect to the portion of obligations hereunder which is assigned or transferred. The Parties further acknowledge and accept that any EIB/BdI/ECB Assignment under Clause 26.3 (Assignment to EIB, Bank of Italy or to the European Central Bank) of the New Banking Facility Agreement may be made only to the extent that the right of the Shareholders to exercise the call option over all the pledged TI Shares under and pursuant to this Agreement is not prejudiced or impaired in any manner whatsoever.

1.2.18 If the option hereunder is not validly exercised and no transfer of Appropriation Shares occurs, each Shareholder who is a Dissenting Party hereby agrees and undertakes that for a period of 6 {six) months from receipt of the Calculation Notice (the “Lock-up Period”), it shall not sell, transfer, exchange either by way of a spot or forward contract or by any other derivative instruments or arrangements of any kind having a similar effect, any shares, convertible instrument or other equity or quasi-equity instruments of Telecom Italia S.p.A. (any such activity, a “Share Disposal”), provided however that such undertaking shall not apply (i) to Mediobanca and Intesa Sanpaolo when appropriating, buying or selling or otherwise transferring shares and other rights in the context of the enforcement of the Shares Pledge Agreement, and (ii) to Mediobanca, Intesa Sanpaolo and Generali when appropriating, buying or selling or otherwise transferring shares and other rights in the context of the ordinary course of their trading activities taking principal positions resulting from client facilitation. For the avoidance of doubt, nothing in this Agreement shall constitute or be interpreted as a restriction, impediment or limitation whatsoever to the right of each Shareholder, whether a Dissenting Party or not, to purchase or appropriate, either by way of a spot or forward contract or by any other derivative instruments or arrangements of any kind having a similar effect, any shares, convertible instrument or other equity or quasi-equity instruments of Telecom Italia S.p.A, at any time (any such activity, a “Share Acquisition”). The Shareholders agree that, during the Lock-up Period, following any enforcement of the Shares Pledge Agreement, they will: (i) use their reasonable efforts to make Share Acquisitions (if any) from the Lenders in priority to any other market counterparty; and (ii) refrain from any trading activity or the making of any intentional, specific, negative briefing (outside of the normal periodic or customary corporate communications of such entity) to either financial market counterparties or the press with respect to Telecom Italia S.p.A.’s shares, which would adversely affect any Share Disposal by the Lenders (or their relevant agents) in the context of an enforcement of the Shares Pledge Agreement.

1.2.19 The Parties (other than HSBC) hereby agree and acknowledge that the option agreement entered into between them on 11 January 2010 is terminated and no longer in force between themselves as of the date of execution of this Agreement.

1.2.20 This Agreement and all the schedules hereto constitute the entire agreement among the Parties and supersede in full any prior understandings, agreements or representations by or among the Parties, written or oral, with respect to the subject matter hereof.

1.2.21 This Agreement shall be governed by, and interpreted in accordance with, the laws of the Republic of Italy. Any disputes arising out of or in connection with this Agreement shall be submitted by the Parties to the Courts of Milan.

Today the Board of Directors has acknowledged the resignation of Mr. Mario Martin, board member designated by Telefonica, and has appointed Mrs. Natalia Sainz Stuyck.

On even date the Board of Directors has approved nine months accounts as of January 31, 2012 with a period loss of Euro 1,001m, after impairment of Telecom Italia investment of Euro 901m. Following such impairment the carrying value of Telecom Italia investment stands at Euro 4,505m or Euro 1.50 per Telecom Italia ordinary share. The adjustment is aligned with the valuation carried out by a first standing international investment bank which issued a fairness opinion in this respect.

In addition, following discussions with shareholders and the banking system, the Board of Directors has approved the framework to refinance the bonds (€1.3bn has already been subscribed for by shareholders pro rata) and the bank debts (€2.1bn), both of which fall due between May and October. The framework, which is currently being finalized, would involve:

Under the terms of the loan facility agreement, as was the case in 2010, the lending banks have granted Telco shareholders a call option over the Telecom Italia shares which may become available to them as a result of a potential enforcement of the pledge. Exercise of this call option is governed by a separate amendment agreement which is part of the existing agreement between shareholders.
