In the case of the Subscription Right, the Purchaser shall likewise be required to adhere to this Agreement at the time of conversion of the bonds or securities into shares entitled to vote or subscription.

11.2. If the selling Party is AG LTDA. and it sells its Affected Shares or Subscription Rights in part to two or more third parties, AG LTDA. (if the sale is partial) and such third party Purchasers shall exercise all the rights collectively and in block as if, for purposes of this Agreement — AG, they were one sole Shareholder, jointly liable for the performance of the obligations hereunder.

11.3.

SECTION XII

SALE OF CORPORATE EQUITY INTERESTS BY THE COMPANY AND BY THE SHAREHOLDERS

12.1. This Agreement does not jeopardize the rules of transfer of the Affected Shares and/or Subscription Rights of Telemar Participações reflected in the General Shareholders Agreement, to which AG and Portugal Telecom are signatories and which shall be complied with where applicable also in the procedural part.

12.2. If AG decides to transfer or in any way sell the totality of the Telemar Participações Affected Shares, even if the transfer is imposed by virtue of the provisions of the General Shareholders Agreement (“Transfer”), the sale of the Telemar Participações Affected Shares shall be binding on the Shareholders to approve the dissolution of the Company and of AG in a Shareholders Meeting of Company and of AG, and the respective Transfer may only be completed once such dissolutions have been resolved, establishing the simultaneous payment to Portugal Telecom and to AG LTDA., in proportion to their respective equity interests in the Company’s capital of the sales price of Telemar Participações Affected Shares, within a maximum term of two (2) Business Days after receipt thereof, as anticipation of the amounts that the Shareholders shall be entitled to receive by virtue of the liquidation of the Company and of AG, after deducting all the taxes due by the Company and by AG and of the amounts required to meet all the other liabilities registered with their respective accountings, including accrual for the expenses required for liquidation and unequivocally demonstrated to the Shareholders (“Credit of Portugal Telecom” and “Credit of AG”, as the case may be). The other assets owned by the Company and by AG shall also be distributed among the Shareholders at the ratio of their equity interests, with due regard for the liquidation procedures.

12.2.1. Should the Transfer of the Telemar Participações Affected Shares be partial, as an alternative to the dissolution, the sale may be completed after the resolution on the adoption of the corporate procedures that result in the refund of the sales price of the Telemar Participações Affected Shares to the Shareholders, with due regard for the other terms and conditions set forth herein, such as redemption of shares, payment of extraordinary dividends, reduction of capital, or any corporate transaction which may be agreed by the Parties.

12.2.2. In the event that, as a result of the refund to the shareholders of the sales price of the Telemar Participações Affected Shares referred to in the previous item 12.2.1, any Taxes, costs and expenses (“Costs”) are due as a result of the liquidation of the Company (and not of AG) or, further, due to the adoption of other procedures which may be adopted for this same purpose and which affect the Company, it shall be AG LTDA.’s liability to pay the Costs, so that Portugal Telecom may receive the amounts that shall be ascribed to it as if the Company did not exist.

12.3. Even if a Transfer of the Affected Rights and/or Subscription Rights issued by Telemar Participações is made by AG, the rights of Portugal Telecom as holder of the Telemar Participações Affected Shares set forth in the General Shareholders Agreement shall not be jeopardized. In this way, Portugal Telecom may in this case exercise its Preemptive Rights in the acquisition of the Affected Shares and/or Subscription Rights issued by Telemar Participações and take part in the offer to purchase it as the General Shareholders Agreement entitles it to do.

12.3.1. If Portugal Telecom purchases the Affected Shares and/or Subscription Rights issued by Telemar Participações held by AG, as Purchaser, or in the exercise of its rights set forth under the General Shareholders Agreement, Portugal Telecom is forthwith authorized by AG LTDA., by the Company and by AG to use the Credit of Portugal Telecom to pay to AG and up to the limit thereof the amount corresponding to the price of purchase or Transfer of the mentioned Affected Shares and/or Subscription rights issued by Telemar Participações purchased by Portugal Telecom.

12.4. Furthermore, if the Company decides to cause AG to make the Transfer of its Telemar Participações Affected Shares, Portugal Telecom shall be entitled to sell collectively with AG the totality of the Affected Shares (and/or Subscription Rights, if this is the case) issued by the Company, the totality of the Affected Shares (and/or the Subscription Rights, if this is the case) issued by LF, as defined in the Shareholders Agreement — LF, and the totality of its Affected Shares (and/or Subscription Rights, if this is the case) issued by Telemar Participações, as defined in the General Shareholders Agreement (“Tag Along Right with the Company”), provided that Portugal Telecom may not exercise its Tag Along Right, only if the Purchaser in the Transfer is any of the shareholders signatories to the General Shareholders Agreement, though they may be LF TEL and/or its controlling shareholders.

12.4.1. Portugal Telecom shall be entitled (but not required) to include in its Tag Along Right with the Company the Shares Without Liquidity (and/or subscription inherent thereto) held by it, as set forth in Section 10.7.1.

12.5. All the procedures and conditions set forth in Section 10.7 to 10.12 for the exercise of the Tag Along Right set forth in Section 12.4 above shall be complied with, mutatis mutandis .

12.6. In the event of Transfer of Affected Shares of the capital of Telemar Participações

held by AG, including if the Transfer derives from the provisions of Section X of the General Shareholders Agreement, and provided that Portugal Telecom has purchased shares issued by Telemar Participações through the exercise of its Preemptive Right, including by taking part in the apportionment of residue, if any, without reconstructing its Equity Interest at the moment immediately prior to its sale, or in the event in which it does not have the right to exercise its preemptive right, as set forth in the General Shareholders Agreement, Portugal Telecom shall be entitled to receive from AG LTDA., from the Company or from AG (which in this case are joint), in the same act of receipt by AG of the price of Telemar Participações Affected Shares obtained at the Transfer, a recomposition amount of its investment which shall be ascertained in accordance with the formula set forth in Exhibit 12.6 (“Recomposition”). The Recomposition shall be ascertained upon valuation of the shares issued by Telemar Participações, according to the rules, methodologies and criteria set forth in the same Exhibit 12.6 (“Valuation Value”). The rule of Recomposition does not apply to the event of Portugal Telecom using its right to a First Offer set forth in Section X above and a sale is made for an amount greater than that offered by Portugal Telecom, regardless of the amount of the shares that it may purchase as a result of the preemptive right set forth in the General Shareholders Agreement.

12.7. Except for the sale of shares issued by Telemar Participações, which shall be subject to the above rules, AG, upon sale of their other Equity Interests, shall have regard for a price not lower than the respective market value, which shall be ascertained according to the average quotation in the stock exchange in the thirty (30) trading sessions prior to the date of sale. In the case of sale of the Shares Without Liquidity, the sales price may not be lower than the value obtained according to the criteria set forth in Exhibit 10.7.1.

12.8. The sale of the Shares Without Liquidity by AG or by Portugal Telecom, when not made in any one of the cases of Tag Along set forth herein, shall respectively entitle Portugal Telecom or AG to take part in the mentioned sale with the same number of TNL and Telemar Without Liquidity Shares of the seller under the intended sale, with due regard for the same terms and conditions, including price, term and form of payment.

12.8.1. With the purpose of organizing the sale set forth in Section 12.8 above, Portugal Telecom and AG shall establish the procedures regarding such sale, within a term of fifteen (15) days counted as from the date of notice of the intention to carry out such sale, as sent by one party to the other.

SECTION XIII

PURCHASES OF EQUITY INTERESTS OF AG

13.1. Without prejudice to the other applicable provisions set forth herein, if AG intends to purchase, per purchase or subscription, shares issued or subscription of shares (or securities convertible into shares) by Telemar Participações, including those that come to be offered to AG by virtue of the preemptive right set forth in the General Shareholders Agreement

(including the right set forth in Section X of the General Shareholders Agreement), the terms and conditions set forth in this Section shall be complied with.

13.2. Portugal Telecom may oppose to AG purchasing shares or rights to subscription of shares (or securities convertible into shares) issued by Telemar Participações if the purchase price is greater than the Valuation Value ascertained according to the Valuation procedures established in Exhibit 13.2 hereof.

13.2.1 For purposes of this Section, the Company may notify Portugal Telecom as to its intention to cause AG to purchase shares or rights to subscription of shares (or securities convertible into shares) issued by Telemar Participações on a timely basis in order that the Valuation Procedures set forth in Exhibit 13.2 may be completed prior to expiration of the term for exercising the preemptive right to subscription of shares and increase of capital or of the term for exercising the Preemptive Right set forth in the General Shareholders Agreement, as the case may be. The notice shall contain all the terms and conditions of the intended acquisition. Once said notice has been received, Portugal Telecom shall have a term of six (6) Business Days to request the Valuation, and its silence shall be understood as waiver of its right to submit opposition, in which case AG shall be free to purchase the shares or rights to subscription of shares (or securities convertible into shares) issued by Telemar Participações pursuant to the terms of the notice made, without regard for the Valuation procedures set forth herein.

13.2.1.1. The Company shall also send to Portugal Telecom a communication advising about the receipt of a Notice (as defined in the General Shareholders Agreement), on the business day immediately subsequent to the receipt of the mentioned Notice.

13.2.2. If the price proposed for purchase of the shares or rights to subscription of shares (or securities convertible into shares) issued by Telemar Participações contained in the notice covered in Section 13.2.1 exceeds the Amount of Valuation by more than ten percent (10%), Portugal Telecom may submit opposition to the purchase intended upon express communication sent to the Company and to AG.

13.3. AG LTDA. and its Affiliates (including the Company) may only purchase shares or rights to subscription of shares (or securities convertible into shares) issued by Telemar Participações by means of AG. However, if Portugal Telecom exercises its right to submit opposition to the purchase pursuant to the terms set forth herein, the shares or rights to subscription of shares (or securities convertible into shares) issued by Telemar Participações may be purchased by AG LTDA. or by any of its Affiliates (except for the Company and AG), in which case it shall assign to AG LTDA. or to its Affiliates (provided that the provisions set forth in Section 8.22 of the General Shareholders Agreement are complied with), in a non-burdensome way, the rights that allow it to purchase the shares or rights to subscription of shares issued by Telemar Participações. If it is not possible for any reason to make an assignment during the period of exercise of the preemptive right, AG, with the funds

supplied by AG LTDA., shall make the acquisition of shares or rights to the subscription of shares (or securities convertible into shares) issued by Telemar Participações, immediately assigning them to it after the purchase to AG LTDA., free of any kind of burden to the Company and to AG.

13.4. Without prejudice to the provisions set forth in Section 13.2.2, the right of Portugal Telecom to submit opposition set forth above may be exercised if Portugal Telecom does not exercise purchase rights by virtue of the General Shareholders Agreement for the acquisition of shares or rights to subscription of shares (or securities convertible into shares) issued by Telemar Participações, whose purchase was intended by AG.

13.5. The Company may create any pledge, guarantee or other Lien on Equity Interest which the Company may have or may come to have, with due regard where applicable for the restrictions and formalities set forth in this Agreement. Such authorization does not encompass the shares issued by AG held by the Company, whose burdening shall always depend on the authorization of Portugal Telecom, in a Shareholders Meeting, pursuant to this Agreement. Additionally, any Lien may only be valid and effective if the lender declares expressly and in writing that it is aware of all the provisions of this Agreement and that it shall have regard for all the rules set forth herein with respect to the provision of the Equity Interests held by the Company. Any Lien that may be imposed on the Equity Interests shall be immediately informed to the Company which, in turn, shall notify all the other Parties about this Agreement.

13.6. Portugal Telecom shall also have the right to oppose the purchase of other Equity Interests by AG, with due regard mutatis mutandis for all the procedures and conditions set forth in Sections 13.2 to 13.5 above, if the purchase price is greater than the respective market value, which shall be determined according to the average quotation in the stock exchange in the thirty (30) trading sessions preceding the purchase date. In the case of purchase of Shares Without Liquidity, Portugal Telecom may also submit opposition if the purchase price exceeds the amount thereof obtained according to criteria set forth in Exhibit 10.7.1.

13.7. Any transactions with the Equity Interests made in disagreement with the procedures and rules established herein shall be ineffective in relation to the Company, to AG and to the Parties and shall not be acknowledged nor be carried out by the Company, by AG and by the Parties.

13.8. Without prejudice to the provisions set forth in Section 13.3 above, AG shall not assign to the Company the rights arising out of its condition of shareholder of Telemar Participações without prior and express consent of Portugal Telecom.
