2. CALL OPTION ON OLIMPIA SHARES

2.1 Grant of Call Option. Subject to the terms and conditions of this Call Option Agreement, Telco hereby irrevocably and unconditionally grants to TE the right to purchase from Telco the Olimpia Shares (as defined below) and, provided that the Call Option is exercised in accordance with the terms and conditions of this Call Option Agreement, Telco irrevocably and unconditionally agrees to transfer the Olimpia Shares for the Olimpia Purchase Price (as defined below) pursuant to the terms set forth in this Article II.

2.2 Consideration. The Call Option is hereby granted to TE by Telco in consideration of the investment commitment in Telco undertaken by TE pursuant to the Co-Investment Agreement and taking into account the overall balance of the economic interests existing between all parties to the Co-Investment Agreement and the Shareholders Agreement. Accordingly, TE and Telco hereby acknowledge and agree that the Call Option on Olimpia Shares shall be deemed to be onerous and not gratuitous.

2.3 Object of the Call Option. Object of the Call Option shall be the number of O shares (or the relevant rights attaching thereto) which the Board of Directors of Telco will have resolved to dispose or encumber, as specified in the relevant Telco’s Board of Directors resolution adopted pursuant to paragraph 1.2(bb) of the Shareholders’ Agreement, (the “Olimpia Shares” and such relevant Telco’s Board of Directors resolution, the “Relevant Telco’s Board of Directors Resolution”).

2.4 Purchase Price. Subject to the exercise of the Call Option, the purchase price to be paid upon Olimpia Closing (as defined below) by TE to Telco as consideration for the Olimpia Shares in the event of any transaction which involves a cash purchase price shall be equal to the price indicated in the Relevant Telco’s Board of Directors Resolution (the “Olimpia Purchase Price”).

In the event of any transaction which involves a non-cash consideration, Telco Directors, on or before the Telco’s Board of Directors called pursuant to paragraph 1.1(c) of the Shareholder’s Agreement, shall determine and unanimously agree in writing on the Olimpia Purchase Price (to be determined as equivalent cash value of such transaction). In the event Telco Directors do not reach an agreement on the Olimpia Purchase Price on or before the Telco’s Board of Directors called to resolve upon the transaction pursuant to paragraph 1.1(c) of the Shareholders’ Agreement (the “First Telco’s Board of Directors”), the Olimpia Purchase Price shall be determined - based on valuation principles generally accepted for transactions similar for size and nature - pursuant to Article 1349, first paragraph, of the Italian Civil Code, by a first tier International Investment Bank (the “Arbitrator”) to be appointed jointly by TE and Telco’ shareholders or, lacking an agreement within 3 days from the First Telco’s Board of Directors, by the Chairman of the Tribunal of Milan (in which case, following the referred term of 3 days, any of the parties, any of the Telco’ shareholders or TE, will be entitled to request such appointment from the Chairman of the Tribunal of Milan). The Parties agree that the Arbitrator shall determine the Olimpia Purchase Price within 5 Business Days from its appointment, based on the criteria indicated above.

The Parties agree that the appointment of the Arbitrator for the determination of the Olimpia Purchase Price shall not prejudice the possibility and efforts of the Telco Directors to reach an agreement also after the First Telco’s Board of Directors up until the date of the Telco’s Board of Directors pursuant to paragraph 1.2(bb) of the Shareholders’ Agreement which, in any case, shall not be called to resolve on the acceptance of the non-cash offer without a prior determination of the equivalent cash value, which will be the Olimpia Purchase Price.

In the event of any transaction which involves the formation of an encumbrance, except as provided for in section 25 below, Telco Directors, prior to the Telco’s Board of Directors called pursuant to paragraph 1.1(c) of the Shareholder’s Agreement, shall determine and unanimously agree in writing on the Olimpia Purchase Price. In the event Telco Directors do not reach an agreement on the Olimpia Purchase Price on or before the First Telco’s Board of Directors, the Olimpia Purchase Price shall be determined - based on valuation principles generally accepted for transactions similar for size and nature - pursuant to Article 1349, first paragraph, of the Italian Civil Code, by the

Arbitrator to be appointed jointly by TE and Telco’ shareholders or, lacking an agreement within 3 days from the First Telco’s Board of Directors, by the Chairman of the Tribunal of Milan (in which case, following the referred term of 3 days, any of the parties, any of the Telco’ shareholders or TE, will be entitled to request such appointment from the Chairman of the Tribunal of Milan). The Parties agree that the Arbitrator shall determine the Olimpia Purchase Price within 5 Business Days from its appointment, based on the criteria indicated above.

The Parties agree that the appointment of the Arbitrator for the determination of the Olimpia Purchase Price shall not prejudice the possibility and efforts of the Telco Directors to reach an agreement also after the First Telco’s Board of Directors up until the date of the Telco’s Board of Directors pursuant to paragraph 1.2(bb) of the Shareholders’ Agreement which, in any case, shall not be called to resolve upon any encumbrance without a prior determination of the Olimpia Purchase Price.

2.5 Exercise of the Call Option.

2.5.1 The Call Option on the Olimpia Shares shall become exercisable by TE upon verification of the following conditions:

(i) the Board of Directors of Telco having resolved in the Relevant Telco’s Board of Directors Resolution to dispose, directly or indirectly in any form of manner (including through measures with equivalent effect, such as mergers or demergers of Telco), or encumber, O shares or any rights attached thereto (including, but not limited to, voting rights), pursuant to Clause 1.2(bb) of the Shareholders Agreement; and

Without prejudice to Article 2.10 below, following the exercise of the Call Option and upon payment of the Olimpia Purchase Price, TE will become the owner of the Olimpia Shares. Any further actions or steps to be taken following the exercise of the Call Option and the granting of any applicable regulatory and/or

antitrust authorisation will be deemed to be merely performance of the obligations to deliver to TE the Olimpia Shares, it being understood that the performance of the aforementioned actions and steps and the fulfilment of the aforementioned obligation will not affect the effectiveness of the transfer which will be deemed to have occurred following the exercise of the Call Option and upon granting of any applicable regulatory and/or antitrust authorisation.

2.6 Time of Exercise. TE shall have the right to exercise the Call Option within thirty days following the date of the conditions under Article 2.5.1 above have occurred.

The Call Option shall be exercised in writing by means of a notice to be sent to the Chairman of the Board of Directors of Telco, including written confirmation that TE has no actual knowledge of any fact or condition such to determine the prohibition of the Olimpia Closing pursuant to Article 2.10 below which cannot be remedied within the 180 days term provided under the same Article 2.10 below.

2.8 Escrow deposit. Immediately upon receipt of the Call Option notice (i) the Olimpia Shares shall be deposited in escrow with a fiduciary company or otherwise, in any case to secure the delivery of the Olimpia Shares, and (ii) subject to deposit in escrow of the full Olimpia Purchase Price, the voting rights thereon shall be exercised in accordance with TE instructions, to the extent permitted by law.

2.9 Closing.

2.9.1 Subject to the exercise of the Call Option, the completion of the acquisition of the Olimpia Shares by TE (“Olimpia Closing”) shall take place within 15 Business Days following:

(a) the relevant written request sent by TE to the Chairman of the Telco Board of Directors, or

(b) if the transaction is subject to any antitrust and/or regulatory authorisation (and subject to Clause 2.10 below), the earlier of (i) the obtaining of such authorisations, or (ii) 180 days from the exercise of the Call Option, or the longer maximum term provided for in the third party proposal triggering the exercise of the Call Option.

2.9.2 At the Olimpia Closing:

(a) TE shall pay to Telco the Olimpia Purchase Price, as well as any applicable stamp duty, transfer charges and notary expenses;

(b) Telco shall meet before the public notary that will be indicated by TE and shall duly endorse in favour of TE and deliver to TE the certificates representing the Olimpia Shares free and clear from any lien, option, charge, or encumbrances of any kind, and a copy of the relevant page of the relevant shareholders’ book containing the annotation attesting that TE

has been registered therein as the owner and the holder of the Olimpia Shares;

(c) Telco shall execute and deliver all other documents and instruments required to be executed or delivered before or at Olimpia Closing, in order to perfect the delivery of the Olimpia Shares to TE.

2.9.3 It is hereby understood and agreed that TE shall be entitled to appoint any company controlled or controlling pursuant to Article 2359, first paragraph, n. 1, of the Italian Civil Code to close the transaction exercising the above mentioned rights and perform the above mentioned obligations at the Olimpia Closing, provided that TE shall remain responsible toward Telco of the full compliance by such person or entity of the Olimpia Closing pursuant to this Clause 2.9.

2.10 Authorizations. If the Olimpia Closing requires any antitrust and/or regulatory authorisation, TE shall prepare and submit to the competent authorities the relevant filing as soon as reasonably possible and the Parties shall cooperate in good faith to obtain such authorisations.

In such event - unless more favourable conditions and/or terms are provided for in the transaction triggering the exercise of the Call Option, in which case TE may opt (at its own unquestionable discretion) to match and benefit of the same conditions and/or terms of such transaction - if, within 180 days from the exercise of the Call Option:

2.10.1 TE is not formally prohibited to proceed with the Olimpia Closing and obtains the necessary EU Commission and/or EU Member State antitrust authorities’ authorisations, then TE will have to acquire the Olimpia Shares in accordance with Section 2.9, irrespective of whether one or more authorisations are still pending or have been granted subject to conditions (including conditions imposed by EU Commission and/or EU Member State antitrust authority), provided however that if a decision of the EU Commission or any EU Member State antitrust authority is not obtained, then the Olimpia Closing shall not occur and no Party shall have any liability for or in connection with such circumstances and within the following six month period Telco shall be free to execute an agreement with the original potential buyer or with any other party for the disposal of the relevant Olimpia Shares under the terms and conditions included in the Relevant Telco’s Board of Directors Resolution (provided that a consideration that is higher than the Olimpia Purchase Price shall always be admitted with no reserves or further need of approval).

2.10.2 Any competent authority has prohibited TE to proceed with the Olimpia Closing, then:

(a) the relevant Olimpia Closing shall not occur and no Party shall have any liability for or in connection with such circumstances and, within the following six month period, Telco shall be free to execute an agreement with the original potential buyer or with any other party for the disposal of

the relevant Olimpia Shares under the terms and conditions included in the Relevant Telco’s Board of Directors Resolution, (provided that a consideration that is higher than the Olimpia Purchase Price shall always be admitted with no reserves or further need of approval), and

(b) in the event Telco receives, at any time, any other unsolicited offer for the acquisition of Olimpia Shares and a new Relevant Telco’s Board of Directors Resolution is passed, then TE will only be entitled to exercise the Call Option on the Olimpia Shares to the extent it gives evidence, through a legal opinion of a primary law firm, that all reasons that motivated the prohibition have been removed. Provided that, if, once again, any competent authority prohibits, also for reasons other than those that have motivated the first prohibition, TE to proceed with the Olimpia Closing, then the Olimpia Closing shall occur in accordance with section 2.9, provided further that in this case TE will be entitled to appoint any person or entity to close the transaction exercising the rights and performing the obligations referred to in Section 2.9 above at the Olimpia Closing and provided further that TE shall remain responsible toward Telco of the full compliance by such person or entity of the Olimpia Closing.
