(“GB,” and together with Embratel and Embrapar, the “Offerors”), each a corporation organized under the laws of the Federative Republic of Brazil, hereby offer to purchase any and all outstanding common shares, no par value (“Common Shares”), and outstanding preferred shares, no par value (“Preferred Shares”), including Preferred Shares represented by American Depositary Shares (“ADSs”), of Net Serviços de Comunicação S.A., a corporation organized under the laws of the Federative Republic of Brazil (“Net”), other than those held by the Offerors or their affiliates, in cash at a price of 26.64 Brazilian reais (“R$”) per Common Share and per Preferred Share (for reference, equivalent to approximately U.S.$ per ADS based on the average of the buy and sell U.S. dollar-Brazilian real exchange rates indicated under “transaction PTAX 800, option 5” published by the Central Bank of Brazil through the SISBACEN system at 7:00 p.m., Brasilia time, on , 2012, which was U.S.$1.00 = R$ ), in each case plus interest at the benchmark interest rate of the Interbank Deposit Certificate, Certificado de Depósito Interbancário (for reference, approximately % on , 2012), calculated pro rata from June 8, 2012 to the Settlement Date (as defined herein), net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase and the related ADS letter of transmittal. ADS holders tendering the Preferred Shares represented by their ADSs through The Bank of New York Mellon, as receiving agent, will receive payment in U.S. dollars, which shall also be net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer. The tender offer is not subject to any conditions other than that the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) be validly tendered.

The tender offer is a “unified offer” for Brazilian purposes, in that it satisfies two different offer requirements under Brazilian law: (i) a mandatory offer in connection with an indirect change in control of Net; and (ii) a voluntary offer in connection with Net’s withdrawal from the Level 2 listing regime of the BM&FBOVESPA – Bolsa de Valores, Mercadorias e Futuros (the “São Paulo Stock Exchange”). After the completion of the tender offer, the Common Shares and Preferred Shares will continue to be listed on the São Paulo Stock Exchange under its general listing regime. The tender offer will be conducted as an auction on the São Paulo Stock Exchange pursuant to Brazilian law and practice, and holders of Common Shares and Preferred Shares must qualify for, and be represented at the auction by, a Brazilian brokerage firm authorized to conduct trades on the São Paulo Stock Exchange (a “Brokerage Firm”).

A holder of ADSs representing Preferred Shares may participate in the tender offer by (1) delivering its ADSs to The Bank of New York Mellon, as receiving agent, and instructing the receiving agent to tender the Preferred Shares underlying those ADSs in the tender offer on its behalf or (2) surrendering its ADSs to JPMorgan Chase Bank N.A., as ADS depositary, withdrawing the Preferred Shares underlying the ADSs from the ADS program and participating directly in the tender offer as a holder of Preferred Shares, in which case the holder needs to allow sufficient time to complete all required steps described in this offer to purchase. See THE TENDER OFFER – Section 3 – “Procedures for Participating in the Tender Offer.” Each ADS represents one Preferred Share of Net.

Questions or requests for assistance may be directed to the U.S. information agent set forth on the back cover of this offer to purchase. Additional copies of this offer to purchase may also be obtained from the U.S. information agent.

You must make your own decision as to whether to tender your Common Shares or Preferred Shares and, if so, how many to tender.

The Tender Offer: We are offering to purchase any and all outstanding common shares, no par value (the “Common Shares”), and outstanding preferred shares, no par value (“Preferred Shares”), including Preferred Shares represented by American Depositary Shares (“ADSs”), of Net Serviços de Comunicação S.A. (“Net”), other than those held by us or our affiliates, in cash at a price of 26.64 Brazilian reais (“R$”) per Common Share and per Preferred Share (for reference, equivalent to approximately U.S.$ per ADS based on the average of the buy and sell U.S. dollar-Brazilian real exchange rates indicated under “transaction PTAX 800, option 5” published by the Central Bank of Brazil (the “Central Bank”) through the SISBACEN system at 7:00 p.m., Brasilia time (“PTAX exchange rate”), on , 2012, which was U.S.$1.00 = R$ ), in each case plus interest at the benchmark interest rate of the Interbank Deposit Certificate, Certificado de Depósito Interbancário (the “CDI Rate,” for reference, approximately % on , 2012), calculated pro rata from June 8, 2012 to the Settlement Date (as defined herein), net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase and the related ADS letter of transmittal. ADS holders tendering the Preferred Shares represented by their ADSs through The Bank of New York Mellon, as receiving agent, will receive payment in U.S. dollars, which shall also be net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer. Such cancellation fees will be remitted to JPMorgan Chase Bank N.A. (“JPMorgan Chase Bank”), as ADS depositary.

The tender offer will be conducted as an auction on the BM&FBOVESPA – Bolsa de Valores, Mercadorias e Futuros (the “São Paulo Stock Exchange”) pursuant to Brazilian law and practice, and holders of Common Shares and Preferred Shares must qualify for, and be represented at the auction by, a Brazilian brokerage firm authorized to conduct trades on the São Paulo Stock Exchange (a “Brokerage Firm”).

•

Reasons for the Tender Offer: The tender offer is a “unified offer” for Brazilian purposes, in that it satisfies two different offer requirements under Brazilian law: (i) a mandatory offer in connection with an indirect change in control of Net (the “Change in Control of Net”); and (ii) a voluntary offer in connection with Net’s withdrawal from the Level 2 listing regime (the “Level 2 Delisting”) of the São Paulo Stock Exchange.

Under the terms of certain shareholders’ agreements to which Empresa Brasileira de Telecomunicações S.A. – Embratel (“Embratel”) and Embratel Participações S.A (“Embrapar”) are parties (the “Shareholders’ Agreements”), upon a change of Brazilian law so that a non-Brazilian entity could legally own a controlling interest in Net, Embrapar would have the right to acquire control over Net. Due to a change in Brazilian law, as of September 12, 2011, a non-Brazilian entity is permitted to own a controlling interest in Net. On March 5, 2012, in accordance with the Shareholders’ Agreements, Embrapar acquired indirect control of Net by exercising its option to purchase from Globo Comunicação e Participações S.A. a controlling stake in GB Empreendimentos e Participações S.A. (“GB”), Net’s controlling shareholder. As a result of the Change in Control of Net, pursuant to applicable Brazilian law and regulations, we are required to offer to purchase all of Net’s Common Shares and Preferred Shares, including Preferred Shares represented by ADSs. See SPECIAL FACTORS – “Background of the Tender Offer.”

The tender offer also has been structured to satisfy the requirements in connection with the Level 2 Delisting. The São Paulo Stock Exchange’s Corporate Governance Level 2 Listing Regulation (the “Level 2

Regulation”) requires that at all times at least 25% of an issuer’s total capital stock be part of a free float consisting of outstanding shares held by persons or entities other than those party to a shareholders’ agreement or the controlling shareholder and its affiliates. We are pursuing the Level 2 Delisting because Net’s free float has fallen below the 25% minimum required under the Level 2 Regulation. After the completion of the tender offer, the Common Shares and Preferred Shares will continue to be listed on the São Paulo Stock Exchange under its general listing regime, but will no longer be subject to certain rules related to mandatory disclosure, tender offers, delisting and deregistration and general corporate governance of the Level 2 Regulation. See SPECIAL FACTORS – “Certain Effects of the Tender Offer.”

•

Relationship between the Offerors and Net: As of August 30, 2010, Embratel and Embrapar together directly owned 38% of the Common Shares and 12.9% of the Preferred Shares, while GB directly owned 51% of the Common Shares. Embratel was the bidder in a tender offer for Net’s Preferred Shares, including those represented by ADSs, which was launched in August 2010 and completed in January 2011, after which Embratel held 193,701,299, or 84.77%, of the Preferred Shares. In March 2012, Embrapar exercised its right under the Shareholders’ Agreements to purchase a controlling stake in GB, and, as of March 31, 2012, it had acquired 1,077,520 or 5.5% of GB’s common shares at a price of R$5.98 per share. Because GB is Net’s controlling shareholder, the change in control of GB also resulted in the Change in Control of Net.

On September 17, 2012, Globo Comunicações e Participações S.A. (“Globo”), Embrapar and Embratel undertook a corporate reorganization of their holdings in GB and Net to address regulatory concerns raised by the Brazilian National Telecommunications Agency, Agência Nacional de Telecomunicações – Anatel. This reorganization involved (i) the transfer of 12,436,716 Common Shares held by GB to EG Participações S.A., an entity controlled by Embrapar (“EG”), through a partial spin-off by GB of these Net shares and the subsequent merger of the spun-off assets with EG; (ii) the transfer of 1,643,988 Common Shares directly held by Globo to EG through a capital increase; and (iii) the transfer of all Common Shares and Preferred Shares directly held by Embrapar and Embratel to GB through a capital increase. See SPECIAL FACTORS — “Background of the Tender Offer” for more information about the corporate reorganization. As a result of the above transactions, Embratel and Embrapar no longer directly own any of Net’s shares, and together they own 100% of GB’s shares. GB directly owns 89,446,769 Common Shares and 223,080,448 Preferred Shares of Net, representing 78.15% of the total number of Net’s Common Shares, 97.63% of the total number of its Preferred Shares (including Preferred Shares represented by ADSs) and 91.13% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG owns 14,080,704 Common Shares, currently representing 12.30% of the total number of Net’s Common Shares, or 4.11% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG has issued and outstanding 7,040,352 common shares and 7,040,352 preferred shares. While EG’s common shares and preferred shares have equivalent economic rights, the preferred shares have no voting rights. Embrapar and Embratel together own 51% of EG’s common shares, and Globo owns the remaining 49% of EG’s common shares and 100% of its preferred shares.

Embrapar, Embratel and Net engage in a variety of transactions in the ordinary course of business and are party to certain commercial agreements, including those governing the lease of optical fibers, the use of broadband internet service, fixed-line telephony services, programming agreements and programming guides as well as certain loan and guarantee agreements. See SPECIAL FACTORS — “Interests of Certain Persons in the Tender Offer; Security Ownership; Transactions and Arrangements Concerning the Common Shares, Preferred Shares and ADSs.”

•

Minimum Price: Pursuant to applicable Brazilian law and regulations, certain minimum price requirements apply to this tender offer that are intended to protect minority shareholders in connection with the Change in Control of Net and the Level 2 Delisting. The offer price represents a premium to the minimum price we are required to pay unaffiliated holders under the Level 2 Regulation as a result of the Change in Control of Net. In addition, at Net’s shareholder meeting held on April 5, 2012, unaffiliated minority shareholders qualified to vote unanimously approved the preparation of a valuation report (the “Valuation Report”) by Banco BTG Pactual S.A. (“BTG Pactual”) to determine the economic value of Net’s Common Shares and Preferred Shares,

which would be the minimum offer price under the Level 2 Regulation for the purposes of the Level 2 Delisting. The offer price is within the price range reflecting the economic value of Net’s shares indicated by BTG Pactual in its Valuation Report, and, while below the midpoint of that range, it is substantially higher than the minimum price we are required to pay in the mandatory tender offer resulting from the Change in Control of Net. See SPECIAL FACTORS – “Valuation Report of BTG Pactual.”

What securities are being sought in the tender offer?

We are offering to purchase all Common Shares and Preferred Shares, including Preferred Shares represented by ADSs.

Who can participate in this tender offer? Who may use this offer document? Why are there separate U.S. and Brazilian offer documents?

holders of Common Shares and Preferred Shares that are not U.S. residents is being published in Portuguese concurrently in Brazil as required under applicable Brazilian law. In addition, a short circular primarily corresponding to the Edital for use by holders of Preferred Shares listed on the Mercado de Valores Latinoamericanos is being published in Spanish concurrently in Spain as required under applicable Spanish law.

U.S. and Brazilian law and practice relating to tender offers are inconsistent in a number of ways. This offer document complies with U.S. law and practice, and the Edital complies with Brazilian law and practice. The terms of the tender offer, however, are the same in all material respects. There are certain minor differences described below under “What are the differences in this tender offer applicable to direct holders of Common Shares and Preferred Shares, on the one hand, and holders of ADSs, on the other hand?” See INTRODUCTION.

What are the differences in this tender offer applicable to direct holders of Common Shares and Preferred Shares, on the one hand, and holders of ADSs, on the other hand?

The terms and conditions of the tender offer are the same for all holders of Common Shares, Preferred Shares and ADSs in all material respects. However, the procedures for accepting the tender offer and tendering securities are not identical for direct holders of Common Shares and Preferred Shares, on the one hand, and holders of ADSs, on the other hand. In addition, holders of Common Shares and Preferred Shares tendering directly in the tender offer will be paid in Brazilian reais, net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase and the related ADS letter of transmittal. ADS holders tendering the Preferred Shares represented by their ADSs through The Bank of New York Mellon, as receiving agent, will receive payment in U.S. dollars, which shall also be net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer.

What is the purpose of the tender offer?

Pursuant to Brazilian law, we are required to offer to purchase all of the Common Shares and Preferred Shares, including Preferred Shares represented by ADSs, because the tender offer is a “unified offer” for Brazilian purposes satisfying two different offer requirements under Brazilian law:

(i)

a mandatory offer in connection with the Change in Control of Net; and

(ii)

a voluntary offer in connection with the Level 2 Delisting.

How much are you offering to pay? What is the form of payment?

The purchase price in the tender offer will be R$26.64 per Common Share and Preferred Share (for reference, equivalent to approximately U.S.$ per ADS based on the PTAX exchange rate of U.S.$1.00 = R$ on , 2012), plus interest at the CDI Rate (for

reference, approximately % on , 2012), calculated pro rata from June 8, 2012 to the Settlement Date (as defined below), properly and timely tendered and not properly withdrawn. Each ADS represents one Preferred Share. Upon the terms and conditions of the tender offer, we will pay this purchase price in cash, net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase and the related ADS letter of transmittal. ADS holders tendering the Preferred Shares represented by their ADSs through The Bank of New York Mellon, as receiving agent, will receive payment in U.S. dollars, which shall also be net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer. We have waived the right to increase the purchase price during the auction on the São Paulo Stock Exchange as provided for under applicable Brazilian law.

When will you pay for the Common Shares and Preferred Shares, including Preferred Shares represented by ADSs, purchased in the tender offer?

The Common Shares and Preferred Shares that we purchase in the tender offer will be purchased through an auction on the São Paulo Stock Exchange that is scheduled to occur at 2:00 p.m., New York City time, on the Auction Date, one business day after the Expiration Date. We will pay for the Common Shares and Preferred Shares purchased in the tender offer on the settlement date (the “Settlement Date”), which we expect will be the third Brazilian business day after the Auction Date, in accordance with the rules established by the clearing and settlement chamber of the São Paulo Stock Exchange. We will make payment in cash, net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase and the related ADS letter of transmittal. As promptly as practicable after receipt of the payment in respect of Preferred Shares purchased in the auction that underlie ADSs, The Bank of New York Mellon, as receiving agent, will convert such payment into U.S. dollars and will distribute the proceeds, net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer. See THE TENDER OFFER – Section 2 – “Acceptance for Payment and Payment for Shares.”

Will holders have to pay fees or brokerage commissions if they tender Common Shares or Preferred Shares?

Each shareholder that sells Common Shares or Preferred Shares directly must pay a combined fee to the São Paulo Stock Exchange and the BM&FBOVESPA Central Depositary, Central Depositária da BM&FBOVESPA (the “Central Depositary”), in an amount equal to 0.035% of the purchase price received by that holder. In addition, the Brokerage Firm that sells Common Shares or Preferred Shares on behalf of a shareholder in the auction may charge a fee or commission for doing so. Each shareholder should consult its Brokerage Firm or other securities intermediary to determine what fees or commissions apply. See INTRODUCTION.

If you are an ADS holder and you hold your ADSs through a broker or other securities intermediary, you should ask such securities intermediary whether any additional fees or brokerage commissions apply in connection with the tender offer.

If you are an ADS holder participating in the tender offer through The Bank of New York Mellon, as receiving agent, you will pay (1) a fee of up to U.S.$5.00 per 100 ADSs or portion thereof for the cancellation of the ADSs representing Preferred Shares purchased in the tender offer, (2) the combined fee of 0.035% of the purchase price payable to the São Paulo Stock Exchange and the Central Depositary described above, and (3) your pro rata portion of the fee or commission charged by the receiving agent’s Brokerage Firm to tender Preferred Shares underlying ADSs on behalf of ADS holders participating in the tender offer. Because the purchase price will be paid in Brazilian reais, you will also pay the expenses of converting Brazilian reais to U.S. dollars. These fees and expenses will be deducted from the proceeds received by the holder. In addition, ADS holders must pay any applicable taxes or governmental charges, including those payable in connection with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer and any other withholding taxes related to their sale.

If you are an ADS holder and elect to surrender your ADSs to JPMorgan Chase Bank, withdraw the Preferred Shares underlying your ADSs from the ADS program and participate directly in the tender offer as a holder of Preferred Shares, you will pay (1) a fee of up to U.S.$5.00 per 100 ADSs or portion thereof for the cancellation of the ADSs you surrender, (2) the combined fee of 0.035% of the purchase price payable to the São Paulo Stock Exchange and the Central Depositary described above, (3) any fee or commission charged by your Brokerage Firm and (4) any applicable taxes or governmental charges.

We intend to fund the tender offer through our available cash resources. Banco Itaú BBA S.A. (“Itaú BBA”), the Brazilian intermediary agent, has agreed to provide a guarantee of settlement of the tender offer, except with respect to a competing offer from a third party. See THE TENDER OFFER – Section 5 – “Source and Amount of Funds” and – Section 2 – “Acceptance for Payment and Payment for Shares.”

Is your financial condition relevant to my decision whether to tender in this tender offer?

We do not think our financial condition is relevant to your decision whether to tender your Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) in the tender offer because (a) the tender offer is being made for all Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), (b) the tender offer is solely for cash, (c) the tender offer is not subject to any financing condition, and (d) Itaú BBA, as Brazilian intermediary agent, has agreed to provide a guarantee of settlement of

the tender offer, except with respect to a competing offer from a third party. See THE TENDER OFFER – Section 2 – “Acceptance for Payment and Payment for Shares.”

Are there any conditions to the tender offer?

There are no conditions to the tender offer other than that the Common Shares and Preferred Shares, including Preferred Shares represented by ADSs, be validly tendered. We are not obligated to purchase any tendered Common Shares or Preferred Shares, including Preferred Shares represented by ADSs, if they are not validly tendered. See THE TENDER OFFER – Section 2 – “Acceptance for Payment and Payment for Shares” and – Section 3 – “Procedures for Participating in the Tender Offer.” As noted below, if a competing bidder makes an offer that the Brazilian Securities and Exchange Commission, Comissão de Valores Mobiliários (“CVM”), approves, the publication of the approved competing bid will automatically make void as a matter of Brazilian law any tenders of any Common Shares and Preferred Shares, including Preferred Shares represented by ADSs, previously made and such securities will be returned to the relevant holders. See THE TENDER OFFER – Section 2 – “Acceptance for Payment and Payment for Shares.”

How long do I have to decide whether to participate in the tender offer?

Holders of ADSs will have from , 2012, the date of the commencement of the tender offer, until the ADS Expiration Time on the Expiration Date whether to tender the Preferred Shares underlying their ADSs through the receiving agent. Holders of ADSs holding through a broker or other securities intermediary should contact that entity, since such entities will establish their own cutoff dates and times that will be earlier than the ADS Expiration Time.

Direct holders of Common Shares and Preferred Shares will have from , 2012, the date of the commencement of the tender offer, until 5:00 p.m., New York City time, on , 2012, or until the expiration of any extension of the tender offer, to decide whether to tender their Common Shares or Preferred Shares in the tender offer. See THE TENDER OFFER – Section 1 – “Terms of the Tender Offer and Expiration Date” and – Section 3 – “Procedure for Participating in the Tender Offer.”

Can the tender offer be extended and under what circumstances?

Yes, although we may only extend the tender offer under the limited circumstances permitted by the applicable rules and regulations of the CVM. We may also be required to extend the tender offer by the rules of the CVM and applicable U.S. securities laws. During any extension of the tender offer, all Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) that were previously tendered and not withdrawn will remain subject to the terms of the tender offer, including the right of a tendering holder to withdraw any or all of its Common Shares, Preferred Shares or ADSs. See THE TENDER OFFER – Section 1 – “Terms of the Tender Offer and Expiration Date” and – Section 3 – “Procedures for Participating in the Tender Offer.”

How will you notify holders if you extend the tender offer?

Any extension of the period of time during which the tender offer is open, thereby delaying acceptance for purchase of and payment for tendered Common Shares and Preferred Shares, would need to be announced prior to the auction on the São Paulo Stock Exchange that is scheduled to occur at 2:00 p.m., New York City time, on the Auction Date, one business day after the Expiration Date.

If we decide to extend the tender offer, we will make a public announcement of such extension no later than 9:00 a.m., New York City time, on the next day after the previously scheduled Expiration Date, as required under the Exchange Act.

Can the tender offer be withdrawn?

Under Brazilian law, we are not permitted to withdraw the tender offer once it commences. However, if a competing bidder makes an offer that the CVM approves, the publication of the approved competing bid will void as a matter of Brazilian law all prior tenders of Common Shares and Preferred Shares, including Preferred Shares represented by ADSs, and such securities will be returned to the relevant holders. See THE TENDER OFFER – Section 4 – “Withdrawal Rights.”

How do holders tender the Preferred Shares underlying ADSs?

An ADS holder may tender the Preferred Shares underlying its ADSs through The Bank of New York Mellon, as receiving agent, prior to the ADS Expiration Time on the Expiration Date, in accordance with the instructions set forth in THE TENDER OFFER – Section 3 – “Procedures for Participating in the Tender Offer” and the accompanying ADS letter of transmittal. Immediately following the ADS Expiration Time, the receiving agent will surrender the validly delivered ADSs to JPMorgan Chase Bank, the ADS depositary, with an instruction to cancel the validly delivered ADSs and authorize their custodian to withdraw the underlying Preferred Shares from their account and deliver those underlying Preferred Shares to the receiving agent’s custodian for further delivery to a Brokerage Firm. The Brokerage Firm will tender those Preferred Shares in the auction by presenting a sell order through the São Paulo Stock Exchange’s Megabolsa electronic trading system, as described in THE TENDER OFFER – Section 2 – “Acceptance for Payment and Payment for Shares.”

As an alternative to tendering the Preferred Shares underlying its ADSs through the receiving agent, an ADS holder may also surrender its ADSs, withdraw the Preferred Shares underlying the ADSs from the ADS program and participate directly in the tender offer as a holder of Preferred Shares. The ADS holder would surrender to JPMorgan Chase Bank the ADSs representing Preferred Shares that it wishes to tender, pay a fee to the ADS depositary in the amount of up to U.S.$5.00 per 100 ADSs or portion thereof for the cancellation of those ADSs and pay any taxes or governmental charges payable in connection with its withdrawal of the Preferred Shares from the ADS program. If an ADS holder surrenders ADSs and receives Preferred

Shares, the Preferred Shares so received will need to be registered at the Central Depositary, and the holder will need to obtain its own foreign investor registration under Resolution No. 2,689/00, as amended, of the Brazilian Conselho Monetário Nacional (the “National Monetary Council”). After the holder appoints a Brazilian representative for purposes of Resolution No. 2,689/00 of the National Monetary Council, the holder must make arrangements for that representative to tender the Preferred Shares on its behalf in the same manner as any other direct holder of Preferred Shares registered at the Central Depositary. The holder will need to take these steps in sufficient time to allow its Brazilian representative to tender on its behalf no later than the Share Expiration Time on the Expiration Date, in the manner described in this offer to purchase.

A beneficial owner of ADSs holding through a broker or other securities intermediary must contact that entity if that beneficial owner desires to participate in the tender offer. See THE TENDER OFFER – Section 3 – “Procedures for Participating in the Tender Offer.”

How do holders tender Common Shares and Preferred Shares?

If you hold Common Shares or Preferred Shares directly, to participate in the tender offer, you must, no later than the Share Expiration Time on the Expiration Date, (1) contact a Brokerage Firm, (2) present certain required documentation and (3) ask the Brokerage Firm to register your Common Shares or Preferred Shares at the Central Depositary and sell them in the auction on your behalf. To sell your Common Shares or Preferred Shares in the auction, your Brokerage Firm must, no later than 11:00 a.m., New York City time, on the Auction Date, present a sell order on your behalf through the São Paulo Stock Exchange’s Megabolsa electronic trading system. If you have invested in Common Shares or Preferred Shares under Resolution No. 2,689/00 of the National Monetary Council (which are registered at the Central Depositary), you should ask your Brazilian representative, for purposes of Resolution No. 2,689/00 of the National Monetary Council, to contact such a Brokerage Firm on your behalf and ensure that you qualify for, and are represented in, the auction by such Brokerage Firm. Preferred Shares held in the custody of Banco Bradesco S.A. (“Bradesco”), Net’s transfer agent, are not registered at the Central Depositary. Holders of Common Shares or Preferred Shares held in the custody of Bradesco should request Bradesco to transfer their Common Shares or Preferred Shares to the custody of the Central Depositary in order to enable a Brokerage Firm to sell the Common Shares or Preferred Shares in the auction on their behalf. It is your responsibility to contact a Brokerage Firm sufficiently in advance of the Share Expiration Time on the Expiration Date, to ensure that Bradesco can transfer your Common Shares or Preferred Shares to the custody of the Central Depositary before the Share Expiration Time on the Expiration Date.

Any holder that does not know whether it holds its Common Shares or Preferred Shares through the Central Depositary or Bradesco should ask its broker or other securities intermediary.

See THE TENDER OFFER – Section 3 – “Procedures for Participating in the Tender Offer.”

Can I withdraw previously tendered Common Shares or Preferred Shares? Can I withdraw previously delivered ADSs? How do I withdraw previously tendered Common Shares or Preferred Shares or previously delivered ADSs?

If you hold Common Shares or Preferred Shares directly and have tendered any of those securities, you or your representative in Brazil must contact the Brokerage Firm that you instructed to sell Common Shares or Preferred Shares in the auction on your behalf in sufficient time to enable the Brokerage Firm to withdraw the order to sell any or all of your Common Shares or Preferred Shares before the beginning of the auction on the Auction Date and must provide any documentation required by the Brokerage Firm.

If you are an ADS holder who has delivered ADSs to the Bank of New York Mellon, as receiving agent, in order to tender the Preferred Shares underlying your ADSs, your signed written notice of withdrawal must be received by the receiving agent prior to the ADS Expiration Time on the Expiration Date. As promptly as practicable upon valid withdrawal, the American Depositary Receipts (“ADRs”) evidencing your ADSs will be returned to you if you directly delivered ADRs to The Bank of New York Mellon, or your ADSs will be credited into The Depository Trust Company account from which they were transferred if you delivered your ADSs to The Bank of New York Mellon through a book-entry transfer. See THE TENDER OFFER – Section 4 – “Withdrawal Rights.”

Do you think this tender offer is fair to holders of Common Shares and Preferred Shares, including Preferred Shares represented by ADSs?

Yes, we believe the tender offer is substantively and procedurally fair to unaffiliated holders of Common Shares and Preferred Shares, including Preferred Shares represented by ADSs. See SPECIAL FACTORS – “Position of the Offerors Regarding Fairness of the Tender Offer.”

What does the board of directors of Net think of the tender offer?

The Level 2 Regulation requires that Net’s board of directors recommend for or against the tender offer. Such recommendation must be announced no later than 15 days following commencement of the tender offer.

In addition, Net must provide a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 and a Transaction Statement on Schedule 13E-3 containing a statement of Net’s position with respect to the tender offer no later than 10 U.S. business days following commencement of the tender offer.

Are there appraisal rights with respect to the tender offer?

No, there are no appraisal or similar rights available in connection with the tender offer.

How will consummation of the tender offer affect untendered Common Shares and Preferred Shares (including Preferred Shares represented by ADSs)?

If you do not tender your Common Shares and Preferred Shares in the tender offer, you will remain a holder of Common Shares or Preferred Shares, as the case may be. There will be no squeeze out transaction or other form of mandatory redemption after completion of the tender offer, because any such transaction is only available under applicable Brazilian law in certain circumstances that are not contemplated in this tender offer. Currently, there are only 10,932,212 Common Shares (9.55% of the total Common Shares) and 5,423,468 Preferred Shares (including Preferred Shares represented by ADSs) (2.37% of the total Preferred Shares) in public circulation. After the completion of the tender offer, the number of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) remaining in public circulation will decrease, and the already small market for such securities may be even further reduced. Depending upon the number of Common Shares and Preferred Shares purchased in the tender offer, the tender offer will likely adversely affect the liquidity and market value of any Common Shares and Preferred Shares held by public shareholders after the tender offer is completed. See SPECIAL FACTORS – “Certain Effects of the Tender Offer.”

We intend to cause Net to take steps necessary to terminate the deposit agreement with JPMorgan Chase Bank and the ADS facility promptly after the tender offer is completed, as set forth below under “Will the ADSs (or the Preferred Shares they represent) be delisted or deregistered in the United States?” If such termination is successful, then the holders of ADSs who did not deliver their ADSs to The Bank of New York Mellon, as receiving agent in the tender offer, or surrender their ADSs to JPMorgan Chase Bank will only be entitled to receive the underlying Preferred Shares or, if such Preferred Shares have not been withdrawn after the termination of the ADS facility within the time permitted under the deposit agreement, the net proceeds from the sale of the Preferred Shares represented by such ADSs in accordance with the terms of the deposit agreement.

Will Net be delisted or deregistered in Brazil following the completion of the tender offer?

Pursuant to a shareholders’ meeting of Net on April 5, 2012, the shareholders of Net voted to approve Net’s withdrawal from the Level 2 listing regime of the São Paulo Stock Exchange, which provides enhanced shareholder protections. Following the tender offer, the Level 2 Delisting will be complete. However, Net will continue to be a registered public company in Brazil and its Common Shares and Preferred Shares will continue to be listed on the São Paulo Stock Exchange under its general listing regime. Unlike the Level 2 Regulation, the general listing regime does not require its listed companies to comply with certain rules related to mandatory disclosure, tender offers, delisting, deregistration and general corporate governance. See SPECIAL FACTORS – “Certain Effects of the Tender Offer.”

Will the ADSs (or the Preferred Shares they represent) be delisted or deregistered in the United States?

We intend to cause Net to terminate the deposit agreement for the ADSs promptly after the tender offer is completed. We also intend to cause Net to take steps following the completion of the tender offer

that are necessary to delist the Preferred Shares and the ADSs from NASDAQ Global Market (“NASDAQ”) and, if the relevant requirements are met, terminate the registration of the Preferred Shares under the Exchange Act. See SPECIAL FACTORS – “Certain Effects of the Tender Offer.”

What are the weighted average trading prices of the Common Shares, Preferred Shares and ADSs for the 60 days prior to the last trading day before the announcement of the tender offer in Brazil?

The weighted average trading prices for the 60 days prior to March 5, 2012, the last trading day before the announcement of the tender offer in Brazil, were R$20.22 per Common Share, R$20.79 per Preferred Share and U.S.$11.99 per ADS.

Does the offer price represent a premium over the weighted average trading prices of the Common Shares, Preferred Shares and ADSs for the 60 days prior to the last trading day before the announcement of the tender offer in Brazil?

Yes, the offer price represents a premium of approximately 28% for the Preferred Shares, of approximately 32% for the Common Shares and of approximately 10% for the ADSs over the weighted average trading prices for the 60 days prior to March 5, 2012, the last trading day before the announcement of the tender offer in Brazil.

What are the minimum prices required to be paid to me for my Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) under Brazilian law?

Pursuant to the Level 2 Regulation, certain minimum price requirements apply to this tender offer that are intended to protect minority shareholders in connection with the Change in Control of Net and the Level 2 Delisting. The minimum price we are required to pay unaffiliated holders as a result of the Change in Control of Net is R$5.98 per Common Share and per Preferred Share (including Preferred Shares represented by ADSs), which is the price attributed to each Common Share of Net indirectly acquired by Embrapar when it purchased a controlling stake in GB, Net’s controlling shareholder. See SPECIAL FACTORS – “Background of the Tender Offer.” In addition, in accordance with applicable Brazilian regulations, the offer price must at least be equivalent to the economic value per Common Share and Preferred Share determined by BTG Pactual in the Valuation Report it prepared in connection with this tender offer. The offer price is within the price range reflecting the economic value of Net’s shares indicated in the Valuation Report, which is between R$25.89 and R$28.34, and, while below the midpoint of that range, it is substantially higher than the minimum price we are required to pay in the mandatory tender offer resulting from the Change in Control of Net. See SPECIAL FACTORS – “Valuation Report of BTG Pactual.”

If I sell my Common Shares or Preferred Shares, including Preferred Shares represented by ADSs, at the offer price, will I secure a premium on the minimum prices required under Brazilian law?

The offer price represents a premium of R$20.66 to the minimum price of R$5.98 we are required to pay unaffiliated holders as a result of the Change in Control of Net. In addition, the offer price is within the price range reflecting the economic value of Net’s shares indicated in the Valuation Report, and, while below the midpoint of that range, it is substantially higher than the minimum price we are required to pay in the mandatory tender offer resulting from the Change in Control of Net.

What are the U.S. federal income tax and Brazilian tax consequences to a tendering shareholder?

The receipt of cash in exchange for Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) pursuant to the tender offer will generally give rise to gain or loss for U.S. federal and Brazilian income tax purposes.

Empresa Brasileira de Telecomunicações S.A. – Embratel (“Embratel”), Embratel Participações S.A. (“Embrapar”) and GB Empreendimentos e Participações S.A. (“GB,” and together with Embratel and Embrapar, the “Offerors”) hereby offer to purchase any and all outstanding common shares, no par value (the “Common Shares”), and outstanding preferred shares, no par value (“Preferred Shares”), including Preferred Shares represented by American Depositary Shares (“ADSs”), of Net Serviços de Comunicação S.A. (“Net”), other than those held by the Offerors or their affiliates, at a price in cash of 26.64 Brazilian reais (“R$”) per Common Share and Preferred Share (for reference, equivalent to approximately U.S.$ per ADS based on the average of the buy and sell U.S. dollar-Brazilian real exchange rates included under “transaction PTAX 800, Option 5” published by the Central Bank of Brazil (the “Central Bank”) through the SISBACEN System at 7:00 p.m., Brasilia time (“PTAX exchange rate”), on , 2012, which was U.S.$1.00 = R$ ), in each case plus interest at the benchmark interest rate of the Interbank Deposit Certificate, Certificado de Depósito Interbancário (the “CDI Rate,” for reference, approximately % on , 2012), calculated pro rata from June 8, 2012 to the Settlement Date (as defined below), net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase and the related ADS letter of transmittal. ADS holders tendering the Preferred Shares represented by their ADSs through The Bank of New York Mellon, as receiving agent, will receive payment in U.S. dollars, which shall also be net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer.

In accordance with applicable Brazilian regulations, subject to the terms and conditions described herein, the Common Shares and Preferred Shares tendered in the tender offer will be purchased through an auction on the BM&FBOVESPA – Bolsa de Valores, Mercadorias e Futuros (the “São Paulo Stock Exchange”) that is currently scheduled to occur at 2:00 p.m., New York City time, on , 2012, one business day after the Expiration Date (the “Auction Date”). We will pay for the Common Shares and Preferred Shares purchased in the tender offer on the settlement date (the “Settlement Date”), which we expect will be the third Brazilian business day after the Auction Date, in accordance with the rules established by the clearing and settlement chamber of the São Paulo Stock Exchange.

On , 2012, the Brazilian Securities and Exchange Commission, Comissão de Valores Mobiliários (“CVM”), approved our structuring of the tender offer as a “unified offer” for Brazilian purposes to satisfy two different offer requirements under Brazilian law in connection with (i) the Change in Control of Net (as defined below); and (ii) Net’s Level 2 Delisting (as defined below).

On March 5, 2012, Embrapar acquired a controlling interest in Net’s controlling shareholder, GB, resulting in the change in control of Net (“Change in Control of Net”). As a result of the Change in Control of Net, pursuant to article 254-A of Brazilian Law No. 6404/76, CVM Instruction 361/02 and Section VIII of the São Paulo Stock Exchange’s Corporate Governance Level 2 Listing Regulation (the “Level 2 Regulation”), we are required to offer to purchase all of Net’s Common Shares and Preferred Shares, including Preferred Shares represented by ADSs. The tender offer also has been structured to satisfy the requirements in connection with Net’s withdrawal from the Level 2 listing regime (the “Level 2 Delisting”) of the São Paulo Stock Exchange. After the completion of the tender offer, the Common Shares and Preferred Shares will continue to be listed on the São Paulo Stock Exchange under its general listing regime.

Pursuant to applicable Brazilian law and regulations, certain minimum price requirements apply to the tender offer that are intended to protect minority shareholders in connection with the Change in Control of Net

and the Level 2 Delisting. The minimum price we are required to pay unaffiliated holders under the Level 2 Regulation as a result of the Change in Control of Net is R$5.98 per Common Share and per Preferred Share (including Preferred Shares represented by ADSs). In addition, in accordance with applicable Brazilian regulations related to the Level 2 Delisting, the offer price must at least be equivalent to the economic value per Common Share and Preferred Share determined by Banco BTG Pactual S.A. (“BTG Pactual”) in the valuation report it prepared in connection with this tender offer (the “Valuation Report”), which is between R$25.89 and R$28.34. The offer price represents a premium to the minimum price we are required to pay unaffiliated holders as a result of the Change in Control of Net, and it is within the price range reflecting the economic value of Net’s shares indicated in the Valuation Report, and, while below the midpoint of that range, it is substantially higher than the minimum price we are required to pay in the mandatory tender offer resulting from the Change in Control of Net.

The tender offer is being conducted concurrently in the United States and Brazil and is open to all holders of Common Shares, Preferred Shares and ADSs. This offer document is intended solely for holders of Common Shares and Preferred Shares that are U.S. residents (within the meaning of Rule 14d-1(d) under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”)), and all holders of ADSs representing Preferred Shares. Holders of Common Shares and Preferred Shares that are not U.S. residents may not use this offer document. A separate offer document, called an Edital, for use by holders of Common Shares and Preferred Shares that are not U.S. residents is being published in Portuguese concurrently in Brazil, as required under Brazilian law. In addition, a short circular primarily corresponding to the Edital for use by holders of Preferred Shares listed on the Mercado de Valores Latinoamericanos is being published in Spanish concurrently in Spain as required under applicable Spanish law.

Subject to the terms described herein, unless the tender offer is extended, to tender Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) in the tender offer a holder must tender: (1) if a holder of ADSs electing to tender the Preferred Shares represented by its ADSs through The Bank of New York Mellon, as receiving agent, no later than 10:00 a.m., New York City time (the “ADS Expiration Time”), on , 2012 (such date, as it may be extended by us, the “Expiration Date”), and (2) if a holder of Common Shares or Preferred Shares, no later than 5:00 p.m., New York City time (the “Share Expiration Time”), on the Expiration Date.

Each shareholder that tenders Common Shares or Preferred Shares in the tender offer and each ADS holder for which the receiving agent tenders Preferred Shares underlying ADSs will be required to pay a combined fee to the São Paulo Stock Exchange and the BM&FBOVESPA Central Depositary, Central Depositária da BM&FBOVESPA (the “Central Depositary”), in an amount equal to 0.035% of the purchase price received by that holder. This fee will be deducted from the proceeds received by that holder.

A beneficial owner of Common Shares or Preferred Shares registered in the name of a broker or other securities intermediary must contact that entity if that beneficial owner desires to tender Common Shares or Preferred Shares and may be charged a fee or commission by that entity for tendering Common Shares or Preferred Shares in the tender offer. In addition, a brokerage firm authorized to conduct trades on the São Paulo Stock Exchange (a “Brokerage Firm”) that tenders Common Shares or Preferred Shares on behalf of any shareholder in the auction, as described in THE TENDER OFFER – Section 2 – “Acceptance for Payment and Payment for Shares,” may charge a fee or commission for doing so. Each shareholder should consult its broker or other securities intermediary to determine what fees or commissions apply. ADS holders participating in the tender offer by tendering the Preferred Shares underlying their ADSs through the receiving agent must pay the applicable fees, taxes and charges described in THE TENDER OFFER – Section 3 – “Procedures for Participating in the Tender Offer.”

The purchase price received by holders of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) participating in the tender offer may be subject to applicable Brazilian withholding taxes. See THE TENDER OFFER – Section 6 – “Certain U.S. Federal Income and Brazilian Tax Consequences.”

Net is also required to file a Solicitation/Recommendation Statement on Schedule 14D-9 and a Transaction Statement on Schedule 13E-3 containing additional information regarding Net’s board of directors’ determination as to whether it is in favor of the tender offer and whether it recommends that holders tender their Common Shares and Preferred Shares in the tender offer no later than 10 U.S. business days following commencement of the tender offer. A copy of the Schedule 14D-9 and Schedule 13E-3 will be furnished to all holders of ADSs and U.S. resident holders of Common Shares and Preferred Shares by Net. Net is required to publish its position in connection with the tender offer pursuant to Brazilian regulations no later than 15 days following commencement of the tender offer. Holders of Common Shares, Preferred Shares and ADSs are urged to read these documents carefully when they become available and as they may be amended from time to time, before making any decision with respect to the tender offer.

This offer to purchase and the related ADS letter of transmittal contain important information that you should read before making any decision in connection with the tender offer.

We are offering to purchase all Common Shares and Preferred Shares as a result of our recent acquisition of the voting control of Net. On March 21, 2005, (a) Embratel entered into a shareholders’ agreement with Globo Comunicações e Participações S.A. and Distel Holdings S.A. (together “Grupo Globo”), and Teléfonos de México, S.A. de C.V. (“Telmex”), as an intervening party, with respect to Net (the “Net Shareholders’ Agreement”) and (b) Embrapar entered into a shareholders’ agreement with Grupo Globo and GB and Telmex, as intervening parties, with respect to GB (together with the Net Shareholders’ Agreement, the “Shareholders’ Agreements”), which included provisions related to the transfer of shares of GB and certain other governance rights of GB and Net. As of the date of the Shareholders’ Agreements, Brazilian law did not permit non-Brazilian entities to directly or indirectly own a controlling interest in Net. Under the terms of the Shareholders’ Agreements, upon a change of Brazilian law so that a non-Brazilian entity could legally own a controlling interest in Net, Embrapar would have the right to acquire from Grupo Globo, and Grupo Globo would have the right to cause Embrapar to purchase from Grupo Globo, subject to certain conditions, an additional interest in the voting capital of GB that would give Embrapar, through GB, control over Net.

Due to a change in Brazilian law, as of September 12, 2011 a non-Brazilian entity is permitted to own a controlling interest in Net. On January 26, 2012, the Brazilian National Telecommunications Agency, Agência Nacional de Telecomunicações – Anatel (“Anatel”), approved the transfer of indirect control of Net to Embrapar pursuant to Act 612, published on February 1, 2012. On March 5, 2012, Embrapar exercised its right under the Shareholders’ Agreements to purchase the controlling stake in GB and purchased 1,077,520 of GB’s common shares at a price of R$5.98 per share. Because GB is Net’s controlling shareholder, the change in control of GB also resulted in the Change in Control of Net, which triggered a mandatory tender offer obligation under Brazilian law.

On March 6, 2012, we announced our intention to commence a tender offer that would be a “unified offer” satisfying three different offer requirements: (i) a mandatory offer in connection with the Change in Control of Net; (ii) a voluntary offer in connection with the Level 2 Delisting; and (iii) a voluntary offer in connection with the deregistration of Net as a public company in Brazil through the cancellation of the registration of the Common Shares and Preferred Shares with the CVM (the “Brazilian Deregistration”). We also announced that our maximum price for the proposed tender offer would be R$26.04, as adjusted in accordance with the variation in the CDI Rate from March 6, 2012. We expressly reserved the right to cancel the tender offer in connection with the Level 2 Delisting and the Brazilian Deregistration if the lower end of the price range indicated by a valuation report prepared in accordance with applicable Brazilian law and regulations were to be higher than the maximum price, as announced.

On April 5, 2012, at Net’s special shareholders’ meeting, Net’s shareholders approved the Level 2 Delisting and the Brazilian Deregistration. At that meeting, unaffiliated holders of minority shares qualified to vote unanimously approved the preparation by BTG Pactual of a valuation report, as required under Brazilian regulations in connection with offers involving a Level 2 Delisting and Brazilian Deregistration. Those Brazilian regulations require us to pay for the preparation of a valuation report by a third-party expert selected in this manner.

BTG Pactual’s Valuation Report presents an analysis and determination of the economic value of Net’s Common Shares and Preferred Shares. On June 6, 2012, we filed with the CVM the Valuation Report, which indicated a price range between R$25.89 and R$28.34. On the following day, we announced that we would set the offer price at the maximum price we had announced on March 6, 2012 (as adjusted by the CDI Rate since that date), or R$26.64 per Common Share and per Preferred Share, including Preferred Shares represented by

ADSs, in each case plus the CDI Rate calculated pro rata from June 8, 2012 to the Settlement Date. In that announcement, we expressly reserved the right not to pursue the Brazilian Deregistration if shareholders representing more than 10% of Net’s outstanding shares not held by us or our affiliates required that Net call a special meeting to consider the preparation of an additional valuation report. The offer price is within the price range reflecting the economic value of Net’s Common Shares and Preferred Shares indicated by BTG Pactual in its Valuation Report, and, while below the midpoint of that range, it is substantially higher than the minimum price we are required to pay in the mandatory tender offer resulting from the Change in Control of Net. See – “Valuation Report of BTG Pactual.”

On June 12, 2012, we submitted a first draft of the Brazilian tender offer document, known as an Edital, to the CVM, describing our proposed unified tender offer (including the Brazilian Deregistration) at the offer price. On June 21, 2012, Net announced it had received a letter from certain shareholders representing more than 10% of Net’s outstanding shares not held by us or our affiliates (the “Petitioning Shareholders”) requesting a special shareholders’ meeting to consider commissioning an additional valuation of Net’s Common Shares and Preferred Shares, and on June 27, 2012, Net’s board of directors issued a notice calling that meeting. On July 5, 2012, we decided not to pursue the Brazilian Deregistration and to proceed with a unified offer relating only to the Change in Control of Net and its Level 2 Delisting, on the basis that the request from the Petitioning Shareholders indicated that we would not be able to obtain the necessary consents from Net’s shareholders to successfully complete the Brazilian Deregistration. On July 11, 2012, Net’s board of directors announced the cancellation of the special shareholders’ meeting, because without a tender offer in connection with the Brazilian Deregistration, an additional valuation report was no longer required under applicable Brazilian law and regulations.

This unified tender offer does not include certain features that would have been part of the offer if we had decided to pursue the Brazilian Deregistration, including in particular (i) the possibility of a mandatory redemption (squeeze out) of minority holders and (ii) a put right that would have been available to holders of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) to put their Common Shares or Preferred Shares to the Offerors for a period of three months, in each case in the event that the Brazilian Deregistration were successful.

On July 19, 2012, we submitted a second draft of the Edital to the CVM, which superseded the first draft of the Edital and reflected the changes to our offer described above. Subsequently, the Petitioning Shareholders asked the CVM to require an additional valuation report and to condition the success of the Level 2 Delisting on the tendering of at least two-thirds of the Common Shares and Preferred Shares. The CVM is analyzing the request of the Petitioning Shareholders and the arguments presented by them and Embrapar. We do not intend to commence the tender offer until the CVM has decided these issues. We believe the Petitioning Shareholders’ arguments have no merit and intend to continue contesting them vigorously before the CVM.

On August 13, 2012, we first filed a draft of this U.S. offer to purchase with the U.S. Securities and Exchange Commission (“SEC”). Following receipt of comments from the CVM, we submitted a third draft of the Edital to the CVM on September 14, 2012. On September 14, 2012, Embrapar announced that it had reached an agreement with Globo to implement a corporate reorganization involving the shares of GB and Net held by Embrapar, Embratel and Globo in order to address Anatel’s concerns about Globo, a Brazilian producer of cable television and other media content, being a part of the group controlling Net. On September 17, 2012, Globo, Embrapar and Embratel undertook the corporate reorganization, which involved (i) the transfer of 12,436,716 Common Shares held by GB to EG Participações S.A., an entity controlled by Embrapar (“EG”), through a partial spin-off by GB of these Net shares and the subsequent merger of the spun-off assets with EG; (ii) the transfer of 1,643,988 Common Shares of Net directly held by Globo to EG through a capital increase; and (iii) the transfer of the 43,509,045 Common Shares and 223,080,448 Preferred Shares directly held by Embrapar and Embratel to GB through a capital increase. As a result of the reorganization of their holdings in GB and Net, Embrapar and Embratel no longer directly hold any shares in Net, and Globo no longer holds any interest in GB. Embratel and Embrapar own 100% of GB’s shares. GB directly owns 89,446,769 Common Shares and 223,080,448 Preferred Shares of Net, representing 78.15% of the total number of Net’s Common Shares, 97.63%

of the total number of its Preferred Shares (including Preferred Shares represented by ADSs) and 91.13% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG owns 14,080,704 Common Shares, currently representing 12.30% of the total number of Net’s Common Shares, or 4.11% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG has issued and outstanding 7,040,352 common shares and 7,040,352 preferred shares. While EG’s common shares and preferred shares have equivalent economic rights, the preferred shares have no voting rights. Embrapar and Embratel together own 51% of EG’s common shares, and Globo owns the remaining 49% of EG’s common shares and 100% of its preferred shares. A total of 10,932,212 Common Shares and 5,423,468 Preferred Shares (including Preferred Shares represented by ADSs), representing 9.55% of the total number of Net’s Common Shares and 2.37% of the total number of Net’s Preferred Shares, are not held by any of the Offerors or their affiliates.

Following receipt of comments from the SEC, we filed a revised draft of this offer to purchase with to the SEC on October 1, 2012. The CVM registered this tender offer and approved the Edital on , 2012.

Purpose of and Reasons for the Tender Offer; Plans for Net Following the Tender Offer

The tender offer is a “unified offer” for Brazilian purposes, which seeks to satisfy two different offer requirements under Brazilian law: (i) a mandatory offer in connection with the Change in Control of Net; and (ii) a voluntary offer in connection with the Level 2 Delisting. In addition, we intend to cause Net to terminate its deposit agreement with JPMorgan Chase Bank N.A. (“JPMorgan Chase Bank”) governing the ADSs promptly after the completion of the tender offer, and subsequently, we intend to cause Net to delist the Preferred Shares and the ADSs from the NASDAQ Global Market (“NASDAQ”), and effect the deregistration of the Preferred Shares under the Exchange Act if the relevant requirements are satisfied.

As a result of the Change in Control of Net, applicable Brazilian law and regulations require us to make this tender offer for all of the Common Shares and Preferred Shares, including those represented by ADSs, not owned by our affiliates, at a price at least equivalent to the price attributed to each Common Share of Net indirectly acquired by Embrapar when it purchased a controlling stake in GB, Net’s controlling shareholder. See – “Background of the Tender Offer.” The tender offer has also been structured to satisfy the requirements in connection with Net’s Level 2 Delisting. The Level 2 Regulation requires that at all times at least 25% of an issuer’s total capital stock be part of a free float consisting of outstanding shares held by persons or entities other than those party to a shareholders’ agreement or the controlling shareholder and its affiliates. We are pursuing the Level 2 Delisting because Net’s free float has fallen below the 25% minimum required under the Level 2 Regulation. We therefore proposed at Net’s special shareholders’ meeting that this mandatory tender offer in connection with the Change in Control of Net also be used to fulfill the tender offer requirements under Brazilian law in connection with a Level 2 Delisting. On April 5, 2012, Net’s shareholders approved the Level 2 Delisting. The Level 2 Regulation requires the offer price to be within the price range reflecting the economic value of Net’s Common Shares and Preferred Shares indicated in the Valuation Report of BTG Pactual filed with the CVM on June 6, 2012, obtained in accordance with applicable Brazilian regulations, and, while the offer price is below the midpoint of that range, it is substantially higher than the minimum price we are required to pay in the mandatory tender offer resulting from the Change in Control of Net. See – “Valuation Report of BTG Pactual.” The requirements to make this offer and the minimum price provisions are intended to protect minority shareholders.

We plan to continue operating Net as a going concern under our control for the foreseeable future. Except as disclosed in this offer document, the Offerors do not have any present plans or proposals that would result in (a) any extraordinary corporate transaction, such as a merger, reorganization, liquidation, or purchase, sale or transfer of a material amount of assets, involving Net or its subsidiaries, (b) any change in the current board of directors or management of Net (including any plans or proposals to change the number or term of directors, to

fill any existing vacancies on the board of directors or to change any material term of the employment contract of any executive officer) or (c) any other material change to Net’s current dividend rate or policy, indebtedness, capitalization or corporate structure or business.

We do not intend to relocate any activities of Net or to close any offices. It is our intent to pursue Net’s current policy related to employment and human resources for employees. We therefore do not expect that the tender offer will have an adverse effect on any of the employees of Net.

We expect to review Net and its assets, corporate structure, capitalization, operations, properties, policies, management and personnel to determine what changes, if any, would be desirable following the completion of the tender offer. We expressly reserve the right to make any changes that we may deem necessary or appropriate in light of our review or in light of future developments. In addition, we regularly review acquisition opportunities in the telecommunications industry and may pursue such opportunities when appropriate.

Regardless of the results of the tender offer, we intend to effect Net’s Level 2 Delisting. We intend to cause Net to terminate the deposit agreement for the ADSs promptly after the tender offer is completed. We also intend to cause Net to take steps following the completion of the tender offer that are necessary to delist the Preferred Shares and the ADSs from NASDAQ and, if the relevant requirements are met, terminate the registration of the Preferred Shares under the Exchange Act. See – “Certain Effects of the Tender Offer.”

We currently intend to retain all of our shares, including those tendered pursuant to the tender offer, but may in the future consider transfers or sales to related companies or other third parties. See – “Certain Effects of the Tender Offer.”

Holders who sell their Common Shares and Preferred Shares, including Preferred Shares represented by ADSs, in the tender offer will cease to have any equity interest in Net or any right to participate in its earnings and future growth. After selling their Common Shares or Preferred Shares, including Preferred Shares represented by ADSs, in the tender offer, such holders also will not bear the risk of any decrease in the value of Net.

If you do not tender your Common Shares and Preferred Shares in the tender offer, you will remain a holder of Common Shares or Preferred Shares, as the case may be. Currently, there are only 10,932,212 Common Shares (9.55% of the total Common Shares) and 5,423,468 Preferred Shares (including Preferred Shares represented by ADSs) (2.37% of the total Preferred Shares) in public circulation. After the completion of the tender offer, the number of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) remaining in public circulation will decrease, and the already small market for such securities may be even further reduced.

Embratel and Embrapar own 100% of GB’s shares. GB directly owns 89,446,769 Common Shares and 223,080,448 Preferred Shares of Net, representing 78.15% of the total number of Net’s Common Shares, 97.63% of the total number of its Preferred Shares (including Preferred Shares represented by ADSs) and 91.13% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. Our ownership of Common Shares and Preferred Shares through GB may be deemed to represent a 91.13% interest in the net book value and a 91.13% interest in the net income of Net, or the equivalent of approximately R$3,968 million (for reference, equivalent to approximately U.S.$ million based on the PTAX exchange rate of U.S.$1.00 = R$ on , 2012) in net book value and R$353.58 million (for reference, equivalent to approximately U.S.$ million based on the PTAX exchange rate of U.S.$1.00 = R$ on , 2012) in net income, respectively, for the year ended December 31, 2011.

In addition, because Embrapar and Embratel together own 51% of EG’s common shares, they may be deemed to beneficially own the 14,080,704 Common Shares currently held by EG, representing 12.30% of the total number of Net’s Common Shares, or 4.11% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG owns 14,080,704 Common Shares, currently representing 12.30% of the total number of Net’s Common Shares, or 4.11% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG has issued and outstanding 7,040,352 common shares and 7,040,352 preferred shares. While EG’s common shares and preferred shares have equivalent economic rights, the preferred shares have no voting rights. Embrapar and Embratel together own 51% of EG’s common shares, and Globo owns the remaining 49% of EG’s common shares and 100% of its preferred shares. Globo owns the remaining 49% of EG’s common shares and 100% of its preferred shares. If all holders of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) not owned by us tender their Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) into the tender offer, we will directly own or may be deemed to beneficially own 100% of Net’s total outstanding shares, and our interest in Net’s net book value and net income will increase to 100%, or the equivalent of approximately U.S.$ million in net book value and U.S.$ million in net income for the year ended December 31, 2011.

We believe that the accounting treatment of the tender offer is not material to the decision of holders of Common Shares or Preferred Shares whether to tender their Common Shares or Preferred Shares into the tender offer. The purchase of Common Shares and Preferred Shares by us in the tender offer will have no effect on the financial statements of Net. For the Offerors, the financial statements of which are not material to you for the reasons stated in this offer to purchase, the acquisition of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) in the tender offer will be accounted for as a purchase.

After the completion of the tender offer, we will withdraw Net’s Common Shares and Preferred Shares from the Level 2 listing regime of the São Paulo Stock Exchange, which provides enhanced shareholder protections, including:

Holders that do not tender their Common Shares and Preferred Shares into the tender offer will no longer be entitled to the benefits of the enhanced shareholder protections of the Level 2 listing regime described above. Following completion of the tender offer, the number of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) remaining in public circulation will decrease and the already small market for such securities may be even further reduced. Depending upon the number of Common Shares and Preferred Shares purchased in the tender offer, the tender offer will likely adversely affect the liquidity and market value of any Common Shares and Preferred Shares held by public shareholders after the tender offer is completed.

The exchange of cash for Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) pursuant to the tender offer will not result in any material Brazilian income tax consequences for the Offerors or Net. The exchange of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) for cash pursuant to the tender offer could give rise to a tax on gains realized by a holder not deemed to be domiciled in Brazil for Brazilian tax purposes. See THE TENDER OFFER – Section 6 – “Certain U.S. Federal Income and Brazilian Tax Consequences.”

We intend to cause Net to terminate the deposit agreement, dated as of July 28, 2006, among Net, JPMorgan Chase Bank, as ADS depositary, and holders and beneficial owners of American Depositary Receipts (“ADRs”) evidencing ADSs of Net, promptly after the tender offer is completed. The ADS depositary is obligated to terminate the deposit agreement at any time at the direction of Net by mailing a notice of termination to the holders of ADSs then outstanding at least 30 days prior to the termination date fixed in such notice. We also intend to cause Net to take steps following the completion of the tender offer that are necessary to delist the Preferred Shares and the ADSs from NASDAQ and, if the relevant requirements are met, terminate the registration of the Preferred Shares under the Exchange Act. As a result, if the termination of the deposit agreement is successful, the holders of ADSs that do not deliver their ADSs to The Bank of New York Mellon, as receiving agent in the tender offer, or surrender their ADSs to JPMorgan Chase Bank will only be entitled to receive the underlying Preferred Shares or, if such Preferred Shares have not been withdrawn after the termination of the ADS facility within the time permitted under the deposit agreement, the net proceeds from the sale of the Preferred Shares represented by such ADSs in accordance with the terms of the deposit agreement.

The ADSs and the Preferred Shares underlying the ADSs are currently registered under the Exchange Act. Following the completion of the tender offer, we intend to cause Net to take the necessary steps to terminate the registration of the ADSs and the Preferred Shares under the Exchange Act if the relevant requirements under applicable U.S. securities laws are met.

Termination of registration of the ADSs and the Preferred Shares underlying the ADSs under the Exchange Act would reduce the information required to be furnished by Net to holders of its securities, would eliminate the obligation of Net to furnish information to the SEC and would make certain provisions of the Exchange Act, such as the requirement to file annual reports with the SEC, no longer applicable with respect to Net.

In addition, if the ADSs and the Preferred Shares are no longer registered under the Exchange Act, the ability of “affiliates” of Net and persons holding “restricted securities” of Net to dispose of such securities pursuant to Rule 144 under the U.S. Securities Act of 1933, as amended, may be impaired or eliminated.

The receipt of cash in exchange for Preferred Shares (including ADSs) pursuant to the tender offer will generally give rise to taxable gain or loss for U.S. federal income tax purposes. See THE TENDER OFFER – Section 6 – “Certain U.S. Federal Income and Brazilian Tax Consequences.”

The ADSs and the underlying Preferred Shares are currently “margin securities” under the regulations of the Board of Governors of the Federal Reserve System. This classification has the effect, among other things, of allowing brokers to extend credit using those securities as collateral. If the ADSs and the underlying Preferred Shares are delisted from NASDAQ, they will no longer constitute “margin securities” for the purposes of the margin regulations and will be ineligible as collateral for margin loans made by brokers.

Holders will not have appraisal or similar rights in connection with the tender offer. No provision has been made to grant unaffiliated shareholders access to the corporate files of Net or to obtain counsel or appraisal services at the expense of the Offerors in relation to the tender offer. The Valuation Report prepared by BTG Pactual, however, is attached as an exhibit to the combined Schedule TO and Schedule 13E-3 to which this offer to purchase relates.

Net is a Brazilian company, and Brazilian law and regulations govern our duties and obligations to Net and the holders of the Common Shares, Preferred Shares and ADSs with respect to the tender offer. As a result of the Change in Control of Net, the Level 2 Regulation requires us to make this tender offer for all of Net’s Common Shares and Preferred Shares, including those represented by ADSs, not owned by our affiliates, at a price at least equivalent to the price attributed to each Common Share of Net indirectly acquired by Embrapar when it purchased a controlling stake in GB, Net’s controlling shareholder. See – “Background of the Tender Offer”. The Level 2 Regulation also requires us to conduct this tender offer for all of the Common Shares and Preferred Shares, including those represented by ADSs, not owned by our affiliates in connection with the Level 2 Delisting at a price reflecting the economic value of Net’s Common Shares and Preferred Shares indicated in the Valuation Report of BTG Pactual filed with the CVM on June 6, 2012, obtained from BTG Pactual in accordance with applicable Brazilian regulations. See – “Valuation Report of BTG Pactual”. The requirements to make this offer and the minimum price provisions are intended to protect minority shareholders.

Other than these requirements, Brazilian law does not impose any obligation on us to make any determination or analysis regarding whether the tender offer is fair to unaffiliated shareholders. Nonetheless, the U.S. “going-private” rules set forth in Rule 13e-3 under the Exchange Act require us (as affiliates of Net for this purpose under U.S. securities laws) to do so. We believe that the tender offer is substantively and procedurally fair to unaffiliated holders of Common Shares and Preferred Shares, including Preferred Shares represented by ADSs.

In reaching our conclusion that the consideration that unaffiliated holders of Common Shares, Preferred Shares and ADSs will receive in the tender offer is fair, and that such transaction is substantively fair to unaffiliated shareholders, we considered and relied upon a number of factors, including the following:

We believe that the procedures governing the tender offer are fair to unaffiliated shareholders for the following reasons:

We recognize, however, that there are also some detriments to holders of Common Shares, Preferred Shares and ADSs who participate in the tender offer, including the following:

We believe that each of the factors above is relevant to unaffiliated holders of Common Shares, Preferred Shares and ADSs. The foregoing discussion of the information and factors we considered is not intended to be exhaustive but includes all material factors we considered. In view of the variety of factors considered in connection with our evaluation of the tender offer, we did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors and considered all factors as a whole in reaching a decision.

We did not consider the third-party sale value or liquidation value of Net because we intend for Net to continue operating as a going concern. We did, however, consider Net’s net book value of R$12.63 per Common Share and Preferred Share as of June 30, 2012 (unaudited), calculated by dividing stockholders’ equity by the number of Common Shares and Preferred Shares. Net’s net book value per Common Share and Preferred Share as set forth in the Valuation Report was R$12.54. This value is substantially below the offer price.

We are not aware of any firm offers made by any unaffiliated party for Net, a controlling interest in Net or a substantial part of Net’s assets during the past two years and therefore did not consider any such offers in reaching our conclusion as to fairness.

None of the Offerors has directly purchased any Common Shares in the two years prior to the date of this offer to purchase, and we therefore did not consider any such purchases in reaching our conclusion as to fairness.

However, when Embrapar exercised its right under the Shareholders’ Agreements to purchase a controlling stake in GB in March 2012, it purchased 1,077,520 of GB’s common shares at a price of R$5.98 per share, and it thereby acquired control over the 58,374,440 Common Shares of Net that GB owns. See Schedule 2 for information about purchases of Preferred Shares by the Offerors in the two years prior to the date of this offer to purchase.

In evaluating the substantive and procedural fairness of the tender offer, we considered the technical objections raised by the Petitioning Shareholders to BTG Pactual’s Valuation Report, which alleged that it contained certain errors, inconsistencies and deficiencies in methodology. As part of its review process, the CVM conveyed the Petitioning Shareholders’ concerns to BTG Pactual and requested that it make certain clarifications in a revised Valuation Report, which we filed on September 14, 2012. Because BTG Pactual (i) did not alter the price range previously indicated as reflecting the economic value of Net’s Common Shares and Preferred Shares; and (ii) addressed the Petitioning Shareholders’ concerns, its revisions to the Valuation Report did not change our position as to the substantive fairness of the tender offer. The decision not to pursue the Brazilian Deregistration meant that a special shareholders’ meeting to discuss the preparation of an additional valuation report was no longer required under applicable Brazilian law and regulations. See SPECIAL FACTORS – “Background of the Tender Offer.” We have respected the procedural safeguards designed to protect minority shareholders under applicable Brazilian law and regulations in this tender offer. We did not consider that commissioning an additional valuation report would be necessary for us to conclude that the tender offer is substantively or procedurally fair.

In making our determinations as to the substantive and procedural fairness of the tender offer, we recognized that no unaffiliated representative has been retained by the members of Net’s board of directors that is not an employee of Net to act solely on behalf of unaffiliated holders of Common Shares, Preferred Shares or ADSs for purposes of negotiating the terms of the tender offer. As noted above, this is not required as a matter of Brazilian law. In any event, the absence of a separate unaffiliated representative did not affect our determination based on the factors set forth above. We recognized that the tender offer is not structured in such a way that agreement with at least a majority of the unaffiliated holders is required. We felt that the absence of such a condition supported our determination, rather than detracted from it. We note that the absence of such a condition means that each and every unaffiliated holder that wants to take advantage of the tender offer can do so, irrespective of the views of the other holders. Accordingly, the absence of such a condition did not affect our determination, based on the factors set forth above, that the tender offer is substantively and procedurally fair to the unaffiliated holders.

Our views as to the fairness of the tender offer to the unaffiliated holders of Common Shares, Preferred Shares and ADSs are not meant, and should not be construed, as a recommendation to any holder as to whether such holder should tender its Common Shares or Preferred Shares, including Preferred Shares represented by ADSs.

Position of Net’s Board of Directors Regarding Fairness of the Tender Offer

Net is a Brazilian company, and Brazilian law and regulations govern the duties and obligations of Net’s board of directors. Pursuant to the Level 2 Regulation, Net’s board of directors is required to provide unaffiliated holders with a reasoned opinion in favor or against the acceptance of the tender offer and may not remain neutral. Such opinion must be presented no later than 15 days following commencement of the tender offer. Net is also required to file a Solicitation/Recommendation Statement on Schedule 14D-9 and a Transaction Statement on Schedule 13E-3 containing additional information regarding Net’s board of directors’ determination as to whether it is in favor of the tender offer and whether it recommends that holders tender their Common Shares and Preferred Shares in the tender offer no later than 10 U.S. business days following commencement of the tender offer. A copy of the Schedule 14D-9 and Schedule 13E-3 will be furnished to holders of Common Shares, Preferred Shares and ADSs by Net. Holders of Common Shares, Preferred Shares and ADSs are urged to read these documents carefully when they become available and as they may be amended from time to time, before making any decision with respect to the tender offer.

The Valuation Report is required to comply with applicable Brazilian regulations. In a tender offer of this type, a valuation report on the economic value of the securities subject to the tender offer must be prepared by an appraiser in accordance with specific procedures established by Brazilian regulations. The Level 2 Regulation, which governs the listing regime currently applicable to Net, sets out requirements for the selection of the appraiser by the unaffiliated holders of minority shares. At a duly called shareholder meeting (at which the required quorum of unaffiliated holders of minority shares was present) held on April 5, 2012, unaffiliated holders of minority shares, by a majority of the votes cast at that meeting, had the option to select from among one of the three independent, specialized third-party valuation firms recommended by the board of directors of Net to prepare the Valuation Report, in accordance with the Level 2 Regulation. At that meeting, unaffiliated holders of minority shares unanimously selected BTG Pactual as the appraiser.

BTG Pactual prepared the Valuation Report with respect to and exclusively for the mandatory tender offer in connection with the Change in Control of Net and the Level 2 Delisting, in accordance with applicable provisions of Brazilian law and regulations.

The Valuation Report is intended solely for the use of the management, the board of directors and the shareholders of Net for the purpose of supporting their respective decisions to participate in the tender offer, as applicable. It was prepared for exclusive use within the context of the tender offer and should not be used for any other purpose. Net’s shareholders should conduct their own analysis of the tender offer and should rely on their own financial, tax and legal advisers when evaluating the tender offer.

The Valuation Report is not, and should not be used as, (i) an opinion as to the adequacy of the tender offer; (ii) a recommendation regarding any aspects of the tender offer; (iii) a valuation report issued for any purposes other than those provided for by applicable Brazilian law and regulations in connection with tender offers of this type; or (iv) an opinion on the adequacy or a determination of a fair price for the tender offer. The Valuation Report was not compiled or created for the purposes of complying with any law or regulation in Brazil or abroad other than those applicable Brazilian laws and regulations described above.

Upon delivery of the Valuation Report by BTG Pactual to us, we paid BTG Pactual a fee of R$664,084.12 for the preparation of the Valuation Report and reimbursed BTG Pactual R$933.93 for its reasonable travel and other out-of-pocket expenses incurred in connection with its engagement. We have also agreed to reimburse BTG Pactual for the remainder of its expenses, including the reasonable fees and expenses of its counsel, and to indemnify BTG Pactual and its affiliates against specific liabilities and expenses arising out of its engagement.

You should consider the following when reading the discussion of the Valuation Report of BTG Pactual:

For the analysis and conclusions contained in the Valuation Report, BTG Pactual carried out the following actions:

In preparing the Valuation Report, BTG Pactual assumed, and relied upon, the accuracy, content, veracity, completeness, sufficiency and integrity of all such Information provided, obtained or discussed with Net or from other public and non-public information (including the Projections), in all material respects. BTG Pactual was not requested to carry out, and did not carry out, (i) any independent verification of any Information or any documentation on which the Information was based that was publicly available or that was provided by Net, its representatives or any third parties for the preparation of the Valuation Report, and, accordingly, does not assume any responsibility for such Information, (ii) any technical audit of Net’s operations, nor any accounting, financial, legal, tax or any other audit of Net or any third parties, (iii) an independent verification or valuation of any of Net’s assets or liabilities (including any non-registered contingency, obligation or financing, property or other assets); (iv) an evaluation of Net’s solvency, in accordance with any bankruptcy, insolvency or similar legislation; or (v) any physical inspection of Net’s properties, facilities or assets.

The Valuation Report applied the discounted cash flow (“DCF”) methodology, which used parameters and financial variables disclosed by the Central Bank that may differ substantially from actual future economic conditions. Furthermore, the DCF methodology does not anticipate changes in the internal and external environment in which Net operates, except for those expressly set out in the Valuation Report. The Valuation Report did not account for financial or operational gains or losses that may occur after the conclusion of the tender offer. The estimates set forth in the Valuation Report and the evaluation resulting from any specific analysis are not necessarily indicative of the actual amounts or results or future values, which may be significantly more or less favorable in relation to those suggested by the analysis. BTG Pactual did not express any opinion about the values at which the Common Shares and Preferred Shares related to the tender offer could trade in the capital markets at any time. The future results of Net may also be affected by market and economic conditions. BTG Pactual shall not be responsible in any manner should the future results of Net differ from those presented in the Valuation Report.

Unless otherwise indicated in the Valuation Report, the Information used in the Valuation Report regarding the accounting, financial and operational position or performance of Net, as well as about the market, was limited to information available as of May 25, 2012. BTG Pactual did not, and does not, undertake any obligation to review, amend or update the Valuation Report, in whole or in part, after May 25, 2012, or to advise of any third party facts or matters of which BTG Pactual may have become aware that would impact the content of the Valuation Report after such date, subject to the applicable terms of Brazilian law and regulations.

The Valuation Report is the result of a complex process involving selection of the most appropriate methods of analysis and their applicability to specific circumstances. In order to reach the conclusions presented in the Valuation Report, BTG Pactual did not assign special weight to any particular factor considered therein, but it took into account the relevant factors as applied to Net’s specific circumstances. The final conclusions of the Valuation Report are the result of such analysis, considered as a whole. Selecting portions of BTG Pactual’s analysis without considering it as a whole could provide only an incomplete view of the processes underlying the Valuation Report.

The Valuation Report is not intended to be the sole basis for an evaluation of Net’s Common Shares and Preferred Shares and, therefore, the Valuation Report does not comprise all the necessary information needed for such purpose. Consequently, it does not represent or constitute any form of recommendation by BTG Pactual in connection with the tender offer. The content of the Valuation Report is not, and shall not be, considered a promise or guarantee with respect to the past or future. The decision to accept or reject the tender offer is solely the responsibility of Net’s shareholders.

The Valuation Report shall not be used for any purpose other than within the strict context of this tender offer without the previous and written authorization of BTG Pactual.

The following is a summary of the material analyses undertaken by BTG Pactual in connection with the preparation of the Valuation Report.

Historical Market Prices. BTG Pactual measured the volume weighted average price of the Common Shares and Preferred Shares of Net for the 30-trading day period, 60-trading day period, 90-trading day period, 180-trading day period and 12-month period preceding the publication of the announcement of the tender offer on March 6, 2012 (the “Material Fact”), as well as for the period between that date and the date of the Valuation Report, on May 25, 2012. Based on this analysis, the volume weighted average price of each Common Share was R$20.22 for the 30-trading day and 60-trading day periods preceding the publication of the Material Fact; R$15.83 for the 90-trading day period preceding the publication of the Material Fact; R$15.80 for the 180-trading day period preceding the publication of the Material Fact; R$15.05 for the 12-month period preceding the publication of the Material Fact; and R$25.93 for the period between the publication of the Material Fact and the date of the Valuation Report. The volume weighted average price of each Preferred Share was R$21.61 for the 30-trading day period preceding the publication of the Material Fact; R$20.09 for the 60-trading day period preceding the publication of the Material Fact; R$19.82 for the 90-trading day period preceding the publication of the Material Fact; R$18.09 for the 180-trading day period preceding the publication of the Material Fact; R$17.43 for the 12-month period preceding the publication of the Material Fact; and R$25.83 for the period between the publication of the Material Fact and the date of the Valuation Report. Accordingly, this historical market price data indicated a volume weighted average price valuation range between R$15.05 and R$25.93 per Common Share and R$17.43 and R$25.83 per Preferred Share, in both cases with the low end of the price range being the volume weighted average price for the 12-month period preceding the publication of the Material Fact and the high end of the price range being the volume weighted average price for the period between the publication of the Material Fact and the date of the Valuation Report. BTG Pactual used a 12-month range because it is consistent with best practices in Brazil and the guidelines provided by applicable Brazilian law and regulations.

Book Value. BTG Pactual measured Net’s book value per share based on the accounting value of Net’s shareholders’ equity as of March 31, 2012 divided by the total number of shares outstanding (excluding treasury shares). As of March 31, 2012, Net’s total shareholders’ equity was R$4,302.4 million, as calculated by subtracting Net’s total liabilities (in the amount of R$4,547.2 million) from its total assets (in the amount of R$8,849.8 million). Net had 343.0 million shares outstanding as of March 31, 2012, thus yielding a book value per share of Net equal to R$12.54.

Discounted Cash Flow Analysis. Based on the Information (including the Projections), BTG Pactual performed a DCF analysis to estimate a range of implied present values per share of Net, as of March 31, 2012. The Weighted Average Cost of Capital (“WACC”) estimated by BTG Pactual was 9.71% in nominal U.S. dollars, reflecting the industry and the country risk of Net and Brazil, respectively. BTG Pactual calculated the WACC using the Capital Asset Pricing Model (“CAPM”), which compares cost of equity to cost of debt, weighted by an estimated capital structure of, to arrive at Net’s nominal discount rate.

Pursuant to CVM Rule 361 and the specific procedures established under Brazilian law regarding valuation criteria, BTG Pactual determined, based on its professional judgment and experience, that the DCF methodology was the most appropriate means of assessing the economic value range of Net’s Common Shares and Preferred Shares.

The main assumptions and Projections that BTG Pactual used in its DCF analysis are:

Macroeconomic Conditions: estimates were based on publicly available data, including information from the Central Bank and the Economist Intelligence Unit, as well as the judgments and internal evaluations of BTG Pactual. BTG Pactual considered various macroeconomic factors in undertaking its DCF analysis, including (i) inflation in Brazil, as measured by both the general index of market prices (Índice Geral de Preços – Mercado) (IGP-M) and the consumer price index, as calculated by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística) (IPC-A); (ii) inflation in the United States, as measured by the U.S. Department of Labor consumer price index (CPI); (iii) the base interest rate in Brazil, known as the SELIC rate; and (iv) the U.S. dollar/real exchange rate.

Net Revenues: estimates were based on the average number of connected households and the average revenue per user (“ARPU”) in the period analyzed, net of taxes and cancellations. Below is the Information (including certain Projections) illustrating Net’s revenues for the periods indicated:

In preparing the Valuation Report, BTG Pactual used the following Information (including certain Projections) illustrating the number of households connected by Net at the end of the periods indicated:

Net had 4.7 million households connected at the end of 2010 and 5.5 million households connected at the end of 2011. The projected number of households connected by the end of 2012 was 6.8 million, which is assumed to increase to 17.4 million households connected by the end of 2021, representing an estimated compound annual growth rate of 11.1% for this forecasted period. BTG Pactual calculated the average number of connected households using the values for households connected at the end of each year analyzed.

In preparing the Valuation Report, BTG Pactual used the following Information (including certain Projections) illustrating Net’s average ARPU per household for the periods indicated:

Net’s ARPU was R$103.99 in 2010 and R$109.10 in 2011. From 2012 to 2021, the projected ARPU increases from R$109.92 in 2012 to R$130.58 in 2021. According to discussions with Net’s management, the projected ARPU compound annual growth rate was assumed to be 1.9% for the period from 2012 to 2021. This rate is lower than the projected inflation rate for the same period due to the following factors: (i) substantial competition in the segments in which Net operates, (ii) price adjustments for a portion of existing customers at a rate below the inflation rate in order to maintain the market share, (iii) migration of certain existing customers to lower-priced service package options, and (iv) reduced prices for certain new customers during Net’s expansion period (particularly between 2012 and 2015).

Households Connected: estimates of new installations were based on Net’s expansion plan and on Net’s average rate of disconnections, or churn rate, for 2010 and 2011.

BTG Pactual used the following Information (including certain Projections) illustrating Net’s new installations for the periods indicated:

Net had 1.3 million new installations in 2010 and 1.5 million new installations in 2011. In the early years of the Projections and in line with Net’s network expansion plans, BTG Pactual assumed greater increases of new installations, from 2.1 million in 2012 to 3.4 million in 2015. The number of projected new installations declined to 2.9 million in 2016 mainly due to Net’s expectation that it will have met its network expansion goals by this time. As a result, from 2016 onwards, BTG Pactual assumed, based on discussions with Net’s management, that Net’s customer base growth would primarily occur in coverage areas already served by Net, thus explaining the projected slowdown in Net’s new installations, which is expected to increase from 2.9 million in 2016 to 3.4 million in 2021.

BTG Pactual used the following Information (including certain Projections) illustrating Net’s churn rate for the periods indicated:

Net’s churn rate was calculated as the number of disconnected households divided by the number of households connected at the beginning of the period, which, based on the Information, yielded a churn rate of 15.4% and 15.8% for 2010 and 2011, respectively, and a projected churn rate of 15.6% per year from 2012 to 2021.

Operating Costs and Expenses: estimated as a function of the average base of households connected per period analyzed. BTG Pactual assumed stable inflation in its analyses of costs and expenses per new customer, per client connected and per households reached. BTG Pactual also considered the number of homes passed as part of its calculation of operating costs and expenses because providing network coverage capabilities to such homes represents a cost without any corresponding income associated with subscription.

BTG Pactual used the following Information (including certain Projections) illustrating the number of homes passed and covered by Net for the periods indicated:

As illustrated in the graph above, Net had approximately 11.8 million and 13.4 million homes passed in 2010 and 2011, respectively. Based on discussions with Net’s management, BTG Pactual assumed that the number of homes passed would increase from 15.9 million in 2012 to 29.4 million in 2021. During Net’s planned expansion period from 2012 through 2015, BTG Pactual assumed an increase in coverage, as measured by the total number of homes passed divided by the total number of urban class A, B and C households (Net’s target

market), from an estimated 37.1% coverage in 2012 to a projected 60.3% coverage by 2015. BTG Pactual projects that coverage will remain relatively stable from 2016 onwards due to Net’s expectation that by 2016 it will have attained its goal of reaching 60% coverage of urban households in income classes A, B and C in the cities where Net operates or plans to operate. Based on discussions with Net’s management, BTG Pactual assumed that expanding beyond 60% of that coverage would be riskier, from a perspective of expected returns, thus explaining the projected plateau in terms of coverage expansion from 2016 to 2021. Net’s management does not intend to invest in network expansion once its goal of 60% coverage of urban households in income classes A, B and C is reached.

Capital Expenditures: based on the estimated amount needed to offset the depreciation of assets and meet the need for operating infrastructure improvements for each year.

In preparing the Valuation Report, BTG Pactual used the following Information (including certain Projections) illustrating Net’s total coaxial cable network extension for the periods indicated:

The capital expenditures estimates were based on the current geographical expansion plans described by Net’s management, which include major investments to expand its network, particularly the coaxial cables network. Net’s total coaxial cables network extension was 52,000 kilometers in 2010 and 58,000 kilometers in 2011. Net projects that its total coaxial cable network will increase from 64,000 kilometers in 2012 to 111,000 kilometers by 2021, representing an estimated compound annual growth rate of 6.3% for this forecasted period.

BTG Pactual used the following Information (including certain Projections) illustrating Net’s capital expenditures, including in relation to its net revenues, for the periods indicated:

The projected increase in capital expenditures as a percentage of net revenue from 2012 through 2015 is, according to discussions with Net’s management, in line with Net’s network coverage expansion plan, which aims to capture new customers on an accelerated basis during this period.

Depreciation and Amortization: calculated based on the depreciation schedule of fixed assets, new investments and amortization of goodwill, in the amount of R$1.3 billion, according to Net’s financial records.

Working Capital: for the periods analyzed, BTG Pactual used working capital amounts in line with average historical ratios of working capital accounts in relation to Net’s net revenues, costs and expenses.

Income Tax and Social Contribution: BTG Pactual used a marginal income tax rate of 34% and the full use of accumulated losses (R$2.8 billion for income taxes and R$3.6 billion for social contribution taxes) for the projected period.

Net Income. In preparing the Valuation Report, BTG Pactual used the following Information (including certain Projections) illustrating Net’s net income and net margin for the periods indicated:

In 2010, Net’s net income and net margin were R$307 million and 5.7%, respectively, and in 2011 Net’s net income and net margin were R$373 million and 5.6%, respectively. From 2012 to 2021, Net’s projected net income increases from R$793 million in 2012 to R$2.2 billion in 2021, with net margins decreasing from 9.8% to 8.3% during the same period.

Terminal Value: the valuation of Net’s assets after the ten-year forecast period, or terminal value, was based on the Gordon perpetuity growth model assuming a growth rate of 2.2%.

WACC Discount Rate: WACC was calculated by combining the estimated cost of equity and estimated cost of debt and adjusting them by Net’s target capital.

The estimated cost of equity was based on (i) a relevered beta of 0.882, which is derived from the average of betas for the two years ended May 25, 2012 of comparable companies operating in the telecommunications sector in Brazil, in each case unlevered by such company’s capital structure and levered by Net’s capital structure, (ii) a risk-free rate of 3.06%, which is based on the average price of 10-year U.S. treasury notes for the three years ended May 25, 2012, (iii) a country risk premium of 2.45%, which is based on the average price of the JPMorgan Chase Bank Emerging Markets Bond Index Plus (EMBI +) Brazil spread for the three years ended May 25, 2012, and (iv) a market risk premium of 6.62%, which represents the estimated long-term expected equity risk premium (historical) as calculated in the 2012 Ibbotson Report.

The estimated cost of debt was assumed to be 11.4%, which was derived from Net’s estimated marginal cost of debt consisting of the average daily CDI Rate, plus a spread of 2.5%.

Net’s target capital was assumed to be 75% equity and 25% debt. The assumed 25% debt ratio is higher than the 15.3% debt ratio of Net’s capital structure as of May 25, 2012. However, BTG Pactual views the higher debt ratio to be consistent with Net’s management practices given that such ratio is expected to be achieved with a low likelihood of adversely affecting Net’s current credit rating.

The enterprise value of Net (the “Enterprise Value”), according to the DCF methodology and based on the assumptions set forth above, was calculated as the sum of (i) the present value of “free cash flows to the firm” on March 31, 2012 of US$537 million, projected for a time horizon of ten years in nominal terms in Brazilian reais,

converted to U.S. dollars at the average exchange rate estimated for each year, discounted at WACC in nominal U.S. dollars of 9.71%; and (ii) the present value of perpetuity (the sum of cash flows generated in all years after the 2012-2021 annual projections) of US$537 million on March 31, 2012, discounted at the same rate used for the “free cash flows to the firm” during the ten-year period. The equity value of Net of R$9,299 million was calculated by (i) subtracting net debt of R$1,649 million and net contingencies (which includes contingency provisions (including tax provisions) and excludes judicial deposits) of R$457 million as of March 31, 2012 from the Enterprise Value, and (ii) adding the present value of the tax benefit from accumulated losses of R$620 million, which assumes losses up to 30% of the tax base for each period discounted at the same WACC and an initial tax base of R$2.8 billion for income tax and R$3.6 billion for social contribution.

This Enterprise Value was then divided by the total number of outstanding common and preferred shares (excluding treasury shares) as of March 31, 2012, which resulted in a price of R$27.12 per share. BTG Pactual then performed a sensitivity analysis of 4.5% in both directions, which resulted in a valuation range per share (common and preferred) between R$25.89 and R$28.34.

In addition, the Valuation Report also shows Net’s EBITDA and EBITDA margins for the periods indicated, which are derived from Information (including certain Projections) used in BTG Pactual’s DCF analysis:

In 2010, Net’s EBITDA and EBITDA margin were R$1.6 billion and 28.8%, respectively, and in 2011, Net’s EBITDA and EBITDA margin were R$1.9 billion and 29.0%, respectively. From 2012 to 2021, Net’s projected EBITDA increases from R$2.4 billion in 2012 to R$7.3 billion in 2021, with EBITDA margins decreasing from 29.6% to 27.7% during the same period. Net’s EBITDA margin is expected to decrease between 2012 and 2013 mainly due to the costs associated with Net’s rapid expansion plan coupled with a projected decrease in ARPU during this period. Such costs include expenses related to the expansion of Net’s business unit responsible for attracting new customers and costs related to supporting new customers, including increased field service and call center support. Net also expects to have additional costs associated with programming updates in order to capture new customers. These additional costs are only partially offset by the dilution of other fixed costs in the period.

The Valuation Report also includes disclosure derived from the Information relating to (i) historical data intended to illustrate the evolution of the Brazilian telecommunications industry, (ii) information with respect to growth trends in the pay-TV, broadband and fixed-line markets for the recent years and comparisons between direct to home (DTH) and cable segments, as well as selected operating data of Net and the other two leading players in the industry, and (iii) a summary overview of Net, which consist of key company events and selected operating data, including Net’s estimated market share in the pay-TV, broadband and fixed-line markets, Net’s subscription volume in 2011, composition of Net’s shareholders’ base and management and Net’s balance sheet and income statement as of and for the period covered therein.

BTG Pactual’s qualifications to render the Valuation Report arise from its extensive experience as a recognized investment banking firm engaged, among other things, in the valuation of telecommunications and

other businesses and their securities, in Brazil and elsewhere, in connection with tender offers, mergers and acquisitions, restructurings, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. A detailed description of BTG Pactual’s qualification is included in the Valuation Report.

BTG Pactual is a financial institution that provides a variety of financial services and other services related to commercial banking, securities, brokerage and investment banking. Each of Net, Embrapar and Embratel have bank accounts with BTG Pactual, and during the last two years, BTG Pactual has exchanged currencies for Embratel in the ordinary course of business and entered into a swap transaction with Net.

In addition, BTG Pactual has provided, directly or through its affiliated companies, certain financial and investment banking services to Net, Embrapar and Embratel, as well as to their controlling shareholders, subsidiaries and affiliates, for which BTG Pactual has received compensation. BTG Pactual continues to provide these services and could, at any time, provide them again. BTG Pactual received a customary fee of R$200,668.86 from Embratel for coordination and distribution services of debentures issued by Embratel in September 2010. BTG Pactual received no other amounts in compensation for financial or investment banking services from Net, Embrapar or Embratel during the past two years.

In the normal course of its activities, BTG Pactual has, directly or through its affiliated companies and proprietary trading accounts, traded equity and debt securities of Net (and currently holds Eurobonds issued by Net), and could, directly or through its affiliated companies and proprietary trading accounts, acquire, hold or sell, on its behalf or on behalf of its clients, shares, debt instruments and other securities and financial instruments (including bank loans and other obligations) of the Offerors, Net and/or their respective affiliates involved in this transaction, as well as provide investment banking services to such companies, controlling shareholders or affiliates and, consequently, could, at any time, retain buying or selling positions with respect to such securities.

BTG Pactual, directly or through its affiliated companies, is or could become a creditor of the Offerors or Net, its subsidiaries and its affiliates, as well as of the controlling shareholders of the Offerors in certain financial transactions.

BTG Pactual has adopted policies and procedures for preserving independence between investment banking and other areas and departments of BTG Pactual and its affiliates, including but not limited to asset management and the proprietary desk for trading shares, debt instruments, securities and other financial instruments.

Other valuations of companies and sectors prepared by BTG Pactual could treat market assumptions in a different way than was reflected in the Valuation Report. The research departments and other departments of BTG Pactual and its affiliated companies may use other analyses, reports and publications, as well as estimates, projections and different methodologies than those used in the Valuation Report, which may contain different conclusions from those set out in the Valuation Report. Valuations of companies and segments that were prepared by other appraisers or by the companies themselves, may treat different factors of analysis in different ways when compared to the approach used in the Valuation Report, and consequently, may present significantly different results.

Interests of Certain Persons in the Tender Offer; Security Ownership; Transactions and Arrangements Concerning the Common Shares, Preferred Shares and ADSs

Embratel and Embrapar own 100% of GB’s shares. GB directly owns 89,446,769 Common Shares and 223,080,448 Preferred Shares of Net, representing 78.15% of the total number of Net’s Common Shares, 97.63% of the total number of its Preferred Shares (including Preferred Shares represented by ADSs) and 91.13% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG owns 14,080,704 Common Shares, currently representing 12.30% of the total number of Net’s Common Shares, or 4.11% of the total number of Net’s Common Shares and Preferred Shares (including Preferred Shares represented by ADSs), taken as a whole. EG has issued and outstanding 7,040,352 common shares and 7,040,352 preferred shares. While EG’s common shares and preferred shares have equivalent economic rights, the preferred shares have no voting rights. Embrapar and Embratel together own 51% of EG’s common shares, and Globo owns the remaining 49% of EG’s common shares and 100% of its preferred shares.

In accordance with Brazilian law and practice, each member of a company’s board of directors must also be a shareholder of such company. Accordingly, upon becoming a member of the board of directors of Net in April 2012, Oscar Von Hauske Solis was given one Common Share by Net. Mr. Von Hauske Solis is also a member of the board of directors of Embratel. Other than Mr. Von Hauske Solis, to the best of our knowledge, none of the directors or executive officers of Embratel, Embrapar or GB, or any of the persons who may be deemed to control us, Telmex Internacional S.A.B de C.V. (“Telmex Internacional”), América Móvil, S.A.B. de C.V. (“América Móvil”), or the members of the Slim Family (as defined below) listed on Schedule 1, beneficially owns any Common Shares or Preferred Shares (other than Common Shares and Preferred Shares held by us) or has engaged in transactions in Common Shares or Preferred Shares since January 6, 2012 (60 days prior to the announcement of the tender offer).

We are indirectly controlled subsidiaries of América Móvil through its subsidiary Telmex Internacional, which as a result may be deemed to be a beneficial owner of the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) owned by us. As of July 31, 2012, Carlos Slim Helú, together with his sons and daughters (together, the “Slim Family”), through their beneficial ownership held by a trust and another entity and their direct ownership of shares, may be deemed to beneficially own approximately 65.6% of the outstanding voting securities of América Móvil. As a result, members of the Slim Family may also be deemed to be beneficial owners of the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) owned by us.

Embratel was the bidder in a tender offer for Net’s Preferred Shares, including those represented by ADSs, which was launched in August 2010 and completed in January 2011. Except in that tender offer and as set forth on Schedule 2, none of the Offerors has directly purchased any Common Shares or Preferred Shares since May 1, 2010. However, when Embrapar exercised its right under the Shareholders’ Agreements to purchase a controlling stake in GB in March 2012, it purchased 1,077,520 of GB’s common shares at a price of R$5.98 per share, and it thereby acquired control over the 58,374,440 Common Shares of Net that GB owns. To the best of our knowledge, there have been no transactions involving Common Shares or Preferred Shares effected by Net or by any pension, profit-sharing or similar plan of Net or the Offerors since May 1, 2010. On September 17, 2012, Globo, Embrapar and Embratel undertook a corporate reorganization of their holdings in GB and Net to address regulatory concerns raised by Anatel, which involved (i) the transfer of 12,436,716 Common Shares held by GB to EG through a partial spin-off by GB of these Net shares and the subsequent merger of the spun-off assets with EG; (ii) the transfer of 1,643,988 Common Shares directly held by Globo to EG through a capital increase; and (iii) the transfer of all Common Shares and Preferred Shares directly held by Embrapar and Embratel to GB through a capital increase. See SPECIAL FACTORS – “Background of the Tender Offer.”

We engage in a variety of transactions in the ordinary course of business with Net and its subsidiaries.

In addition to provisions regarding the transfer of Net’s shares and of GB’s shares, the Shareholders’ Agreements to which we are a party contain provisions relating to, among other things, rights of first refusal and governance, including the right of each of Grupo Globo, Embrapar and Embratel, acting together, and GB to appoint members to Net’s board of directors and board of executive officers. We have agreed that the terms and conditions of the Shareholders’ Agreements shall continue to govern the relationship between Embrapar and Globo and shall also apply to EG until the time that a new shareholders agreement between EG and Net is executed.

On November 22, 2005, Net entered into an agreement with Embratel pursuant to which Net leases new and surplus optical fibers, i.e., disconnected optical fibers, to Embratel for an initial term of 10 years (the “Optical Fiber Lease Agreement”). Lease payments under this Optical Fiber Lease Agreement are made on a monthly basis and are calculated based on use. The Optical Fiber Lease Agreement, as amended, prohibits Embratel from providing certain pay-television and residential Internet broadband services through the subject optical fibers and prohibits Net from providing certain voice and corporate Internet broadband services through the subject optical fibers. Under the Optical Fiber Lease Agreement, Embratel has a right of first refusal to acquire Net’s optical fiber network should Net decide to sell it or any part thereof. The amount paid by Embratel to Net under the Optical Fiber Lease Agreement totaled R$8,939,808 in 2011 and R$9,145,111 in 2010.

On December 29, 2009, Embratel entered into two Indefeasible Right of Use agreements with Net, each with a term of five years beginning on December 1, 2009, to (i) allow Net to use Embratel’s network to provide Net’s broadband Internet service in exchange for a one-time payment in the amount of R$849.6 million; and (ii) allow Embratel to use Net’s transmission capacity to provide fixed telephony services in exchange for a one-time payment in the amount of R$873.5 million.

Other transactions involving Net and companies related to Embratel, such as private circuits for internal fixed-line telephony services and general fixed telephony services, are provided at what Net believes to be market-rate prices. The amount Net paid to Embratel for these services, together with bandwidth access to the Internet, totaled R$531.9 million in 2011 and R$370.7 million in 2010.

Net entered into agreements with Embratel in 2006 to offer fixed-line telephony services and small and medium business services. According to the agreement governing the fixed-line telephony services, Net is responsible for managing the operation of such services and Embratel, which owns the licenses to provide the fixed-line telephony services, is responsible for investments in infrastructure to offer the services and for providing customer service expertise for the fixed-line telephony business. Pursuant to the partnership agreement governing the fixed-line telephony services, Net will share the fixed-line telephony services’ operating results, calculated by subtracting taxes on revenues and interconnection fees and costs incurred in connection with defaulting end users from gross fixed-line telephony revenues. According to the agreement governing small and medium business services, as amended, Net is responsible for the infrastructure that provides Embratel corporate internet protocol access telecommunication services, including certain equipment and general field services. Embratel is responsible for offering broadband Internet and fixed-line telephony services, providing certain equipment and adapting and managing its information technology systems and applications in connection with the services provided to small and medium business. Net’s net sales arising from fixed-line telephony services and small and medium business services amounted to R$572.7 million and R$451.1 million for the years ended December 31, 2011 and 2010, respectively.

Net entered into a Loan and Guaranty Agreement, dated as of June 19, 2008 (the “Loan and Guaranty Agreement”) with Banco Inbursa S.A., an affiliate of Telmex Internacional, our controlling shareholder, and certain of Net’s subsidiaries as guarantors. The Loan and Guaranty Agreement provides for a U.S.$200 million

term loan facility (the “Term Credit Facility”) guaranteed by Net’s subsidiaries that are a party thereto. Interest on borrowings under the Term Credit Facility accrues at a rate of 7.875% per annum and is payable in arrears on April 15 and October 15 of each year. On June 24, 2008, Net drew down the full amount available under the Term Credit Facility. The Term Credit Facility matures on June 18, 2019 and amortizes in three equal installments as follows: one-third on June 18, 2017, one-third on June 18, 2018 and one-third on June 18, 2019. The Term Credit Facility is pre-payable in whole or in part, at any time after the fifth anniversary of the draw date, together with accrued and unpaid interest on the amount prepaid plus certain prepayment fees. Net paid Banco Inbursa S.A. a fee of U.S.$1.2 million in connection with entry into the Loan and Guaranty Agreement, which was deferred and will be amortized over the term of the facility using the interest method.

Net Brasil S.A. (“Net Brasil”) is controlled by Embrapar. On June 27, 2004, Net entered into a programming agreement with Net Brasil whereby it obtains all of its programming from Brazilian sources through Net Brasil for an automatically renewable term of ten years. Net paid Net Brasil a fixed brokerage service fee equal to R$154,412 per month, adjusted by the Consumer Price Index. On June 27, 2004, Net also entered into a licensing agreement with Net Brasil, whereby Net Brasil grants Net the right to use the “NET” brand name for 10 years from the date of effectiveness and, in the case of termination, for an additional 30 months from the date of termination. On December 16, 2005, Net entered into an amended agreement with Net Brasil whereby Net extended the term of the current licensing agreement until 2015. Much of the programming that Net purchases through Net Brasil is produced by Globosat Programadora Ltda. (“Globosat”), which is wholly-owned by Grupo Globo, and its affiliates. Pursuant to Net’s programming agreements with Net Brasil, we recognized expenses of R$1,087.7 million to Net Brasil in 2011, including programming from Globosat and the brokerage fee.

Upon the terms and conditions described in this offer to purchase and the related ADS letter of transmittal, the Offerors are offering to purchase any and all Common Shares and Preferred Shares, including Preferred Shares represented by ADSs, of Net that are properly and timely tendered and not properly withdrawn, at a price in cash of R$26.64 per Common Share and Preferred Share (for reference, equivalent to approximately U.S.$ per ADS based on the PTAX exchange rate of U.S.$1.00 = R$ on , 2012), in each case plus interest at the CDI Rate (for reference, approximately % on , 2012), calculated pro rata from June 8, 2012 to the Settlement Date, net of the stock exchange and settlement fee described in the next sentence, any applicable brokerage fees or commissions and applicable withholding taxes. Each shareholder whose Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) are purchased in the tender offer must pay a combined fee to the São Paulo Stock Exchange and the Central Depositary in an amount equal to 0.035% of the purchase price received by that holder. This fee will be deducted from the proceeds received by that holder. ADS holders tendering the Preferred Shares represented by their ADSs through The Bank of New York Mellon, as receiving agent, will receive payment in U.S. dollars, which will also be net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer.

Subject to the exceptions described herein, unless the tender offer is extended, to tender Common Shares or Preferred Shares or (including Preferred Shares represented by ADSs) in the tender offer, a holder must tender:

In accordance with applicable Brazilian regulations, the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) tendered in the tender offer will be purchased through an auction on the São Paulo Stock Exchange that is currently scheduled to occur at 2:00 p.m., New York City time, on the Auction Date. If we extend the Auction Date, we will also extend the Expiration Date. See Section 3 – “Procedures for Participating in the Tender Offer” for information about participating in the tender offer. On the Auction Date, Brokerage Firms acting on behalf of holders that wish to participate in the tender offer will present sell orders for the applicable Preferred Shares in the auction, as described in Section 2 – “Acceptance for Payment and Payment for Shares.”

ADS holders may tender the Preferred Shares underlying their ADSs through The Bank of New York Mellon, as receiving agent, in accordance with the instructions set forth below under Section 3 – “Procedures for Participating in the Tender Offer” and in the accompanying ADS letter of transmittal. The receiving agent will surrender those ADSs to the ADS depositary and tender the Preferred Shares underlying the ADSs in the auction, as described in Section 2 – “Acceptance for Payment and Payment for Shares.” As an alternative to participating in the tender offer through the receiving agent, an ADS holder may also surrender its ADSs to JPMorgan Chase Bank, as ADS depositary, withdraw the Preferred Shares underlying the ADSs from the ADS program and participate directly in the tender offer as a holder of Preferred Shares, in which case holders need to allow sufficient time to complete all required steps described in this offer to purchase and the related ADS letter of transmittal before the Share Expiration Time on the Expiration Date. See Section 3 – “Procedures for Participating in the Tender Offer.”

Unless the tender offer is extended, ADS holders who have tendered the Preferred Shares underlying their ADSs through The Bank of New York Mellon, as receiving agent, will be entitled to withdraw from the tender offer up until the ADS Expiration Time on the Expiration Date.

We will pay the purchase price for all Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) properly and timely tendered, not properly withdrawn and purchased in the auction on the third Brazilian business day following the auction. As promptly as practicable after receipt of that payment, The Bank of New York Mellon, as receiving agent, will convert that payment into U.S. dollars and will distribute the U.S. dollars to the holders of ADSs representing Preferred Shares accepted for purchase in the tender offer. See Section 2 – “Acceptance for Payment and Payment for Shares.”

The tender offer is not subject to any conditions other than that the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) be validly tendered.

To the extent permitted by applicable Brazilian and U.S. securities laws, the CVM, the SEC and the terms of the tender offer, we reserve the right, at any time (1) to extend the period of time during which the tender offer is open and thereby delay the purchase of Common Shares and Preferred Shares through an auction on the São Paulo Stock Exchange and payment for tendered shares and (2) to amend the tender offer in any respect. Any such extension, delay, waiver or amendment will be followed as promptly as practicable by public announcement thereof, such announcement in the case of an extension to be made prior to the Auction Date, in accordance with Brazilian law. Subject to applicable law (including Rule 14e-1 under the Exchange Act, which requires that material changes be promptly disseminated to shareholders in a manner reasonably designed to inform them of such changes) and without limiting the manner in which we may choose to make any public announcement, we will have no obligation to publish, advertise or otherwise communicate any such public announcement in the United States other than by issuing a press release to the Dow Jones News Service, the Public Relations Newswire or Business Wire.

If we make a material change in the terms of the tender offer or the information concerning the tender offer, we will extend the tender offer to the extent required by Rules 14d-4(d), 14d-6(c) and 14e-1 under the Exchange Act and to the extent permitted under applicable Brazilian law and regulations. We have waived the right to increase the purchase price during the auction on the São Paulo Stock Exchange as provided for under applicable Brazilian law. If we decide to increase the purchase price being offered in the tender offer in the event of a competing offer from a third party as described below, the increase in the purchase price being offered will be applicable to all shareholders whose Common Shares and Preferred Shares are accepted for purchase in the tender offer. If at the time notice of any such increase in the consideration being offered is first published, sent or given to holders of those Common Shares and Preferred Shares, the tender offer is scheduled to expire at any time earlier than the tenth business day from and including the date that such notice is first so published, sent or given, the tender offer will be extended at least until that tenth business day after such notice.

This offer to purchase, the related ADS letter of transmittal and other relevant materials will be mailed by us to the record holders of ADSs and the U.S. resident record holders of Common Shares and Preferred Shares whose names appear on the shareholder lists maintained by the Central Depositary and Banco Bradesco S.A. (“Bradesco”), the list of record holders of ADSs maintained by JPMorgan Chase Bank, as ADS depositary, and the security position listing of The Depository Trust Company (“DTC”), as the book-entry transfer facility for ADSs of Net, and will be furnished, for subsequent transmittal to the beneficial owners of ADSs and the U.S. resident beneficial owners of Common Shares and Preferred Shares, to Brokerage Firms or other securities intermediaries and similar persons whose names, or the names of whose nominees, appear on the shareholder lists or, if applicable, who are listed as participants in the security position listing of the DTC. We will reimburse brokers and other securities intermediaries for customary handling and mailing expenses incurred by them in forwarding the tender offer materials to their customers. We will also mail this offer to purchase, the related ADS letter of transmittal and other relevant materials to any registered or beneficial holder of Common Shares, Preferred Shares or ADSs that requests a copy of the tender offer materials.

For purposes of this offer to purchase and the related ADS letter of transmittal:

The Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) tendered in the tender offer will be purchased through an auction on the São Paulo Stock Exchange. The auction is currently scheduled to occur at 2:00 p.m., New York City time, on the Auction Date.

Sell orders from Brokerage Firms tendering Common Shares and Preferred Shares on behalf of tendering shareholders, including the receiving agent’s Brokerage Firm tendering Preferred Shares underlying ADSs on behalf of ADS holders participating in the tender offer, must be submitted no later than 11:00 a.m., New York City time, on the Auction Date through the São Paulo Stock Exchange’s Megabolsa electronic trading system using the code “NETC3L” and “NETC4L” for Common Shares and Preferred Shares, respectively. Sell orders for tendered Common Shares and Preferred Shares that have not been withdrawn before the beginning of the auction on the Auction Date or, in the case of Preferred Shares represented by ADSs, before the ADS Expiration Time on the Expiration Date, will be deemed accepted for purchase and may not be withdrawn. All Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) purchased by us in the tender offer will be acquired through buy orders at the price set forth in this offer to purchase presented by Embratel, Embrapar and GB through Itaú Corretora de Valores S.A. (“Itaú Corretora”), an affiliate of Banco Itaú BBA S.A. (“Itaú BBA”), our intermediary agent in Brazil for the tender offer. Subject to the terms and conditions of the agreement with Itaú BBA as intermediary agent and the tender offer documents in Brazil, Itaú BBA guarantees the settlement of the tender offer, except with respect to a competing offer from a third party, as described below.

Under the rules of the CVM, a third party is permitted to commence a competing tender offer for all or a part of the Common Shares or Preferred Shares subject to this tender offer, so long as the competing offeror offers a price at least 5% greater than the price offered in this offer to purchase and complies with other provisions of applicable Brazilian law, including the publication of offering materials in Brazil. Any such competing offer must be filed with the São Paulo Stock Exchange no later than 5:00 p.m., Brasília time (4:00 p.m., New York City time) ten Brazilian business days immediately preceding the Auction Date. In such an event, the Auction may be postponed or shareholders may be required to take such additional actions to participate in the tender offer as may be announced by us. In the event of such a competing tender offer, we may, in our sole discretion but subject to Brazilian law, CVM regulations and the Exchange Act and the rules and regulations thereunder (including without limitation, the requirement under Rule 14e-1 that we extend the tender offer if we increase the purchase price offered), submit a higher counteroffer for the Common Shares or Preferred Shares sought by the competing offeror. In the event that the date of the Auction is extended or we otherwise modify the terms of the tender offer, we will make an announcement of that fact in the manner described in Section 1 – “Terms of the Tender Offer and Expiration Date.”

We will pay for the Common Shares and Preferred Shares purchased in the tender offer on the Settlement Date, which we expect will be the third Brazilian business day after the Auction Date, in accordance with the rules established by the clearing and settlement chamber of the São Paulo Stock Exchange. We will make payment in cash, net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase and the related ADS letter of transmittal. As promptly as practicable after receipt of the proceeds, The Bank of New York Mellon, as receiving agent, will convert such proceeds into U.S. dollars and will

distribute them to the holders of ADSs representing Preferred Shares accepted for purchase in the tender offer; net of expenses for converting Brazilian reais to U.S. dollars, any applicable taxes and fees associated with the cancellation of the ADSs representing Preferred Shares purchased in the tender offer.

To tender Common Shares and Preferred Shares (including Preferred Shares underlying ADSs) in the tender offer, a holder must follow the procedures indicated below. The steps a holder must follow in order to tender differ according to whether it holds ADSs representing Preferred Shares or it holds Common Shares or Preferred Shares directly.

A direct holder of Common Shares or Preferred Shares wishing to tender his or her shares must, no later than the Share Expiration Time on the Expiration Date, qualify to participate in the auction (to “qualify for the auction” or “qualify”). To qualify, a holder must, either personally or by means of a duly appointed proxy, contact any Brokerage Firm, present the documentation listed below and ask the Brokerage Firm to represent him or her at the auction.

Common Shares and Preferred Shares held directly are generally held either through the Central Depositary, the custodian for Net’s Common Shares and Preferred Shares that are traded on the São Paulo Stock Exchange, or through Bradesco, Net’s depositary of its book-entry shares. Settlement of the tender offer will occur through the facilities of the Central Depositary. Holders of Common Shares or Preferred Shares under Resolution No. 2,689/00 of the Brazilian Conselho Monetário Nacional (the “National Monetary Council”) hold their securities through the Central Depositary. These holders should ask their respective Brazilian representative for purposes of Resolution No. 2,689/00 of the National Monetary Council to contact a Brokerage Firm on their behalf and ensure that they qualify for, and are represented in, the auction by such Brokerage Firm. To qualify for the auction, a holder whose Common Shares or Preferred Shares are held through Bradesco must, in addition to presenting the documentation listed below to its Brokerage Firm, have Bradesco transfer its Common Shares or Preferred Shares to the custody of the Central Depositary in accordance with the rules, terms and procedures of the São Paulo Stock Exchange. Before accepting an order to transfer Common Shares or Preferred Shares to a Brokerage Firm, Bradesco will generally check the personal information for that holder in its records against the personal information the holder has provided to the Brokerage Firm in the documentation listed below to make sure they are the same. If there are inconsistencies between the records, Bradesco will not transfer the Common Shares or Preferred Shares. It is the responsibility of any shareholder through Bradesco to ensure that the information it provides to its Brokerage Firm is consistent with that in Bradesco’s records. It is also the shareholder’s responsibility to contact a Brokerage Firm sufficiently in advance of the Share Expiration Time on the Expiration Date, to ensure that Bradesco can transfer the shareholder’s Common Shares or Preferred Shares to the custody of the Central Depositary before the Share Expiration Time on the Expiration Date.

Any holder that does not know whether it holds its Common Shares or Preferred Shares through the Central Depositary or Bradesco should ask its broker or other securities intermediary. In addition, any holder that has invested directly in Common Shares or Preferred Shares in Brazil other than through Resolution No. 2,689/00 of the National Monetary Council should consult its broker, securities intermediary, lawyer or other professional advisor without delay regarding the steps it would need to follow in order to qualify for the auction. Such a holder may need to change the form of its investment under applicable Brazilian law and regulations to qualify, and may not be able to make that change in time to participate in the tender offer.

In order to qualify for the auction, a shareholder must present the following documents and any additional information or documents that may be requested by the São Paulo Stock Exchange’s Clearing and Settlement Chamber, Bradesco or its Brokerage Firm:

Direct holders of Common Shares or Preferred Shares that fail to timely deliver all documents required to qualify for the auction, or that fail to transfer their shares to the custody of the Central Depositary, will not qualify for the auction.

Direct holders of Common Shares or Preferred Shares that qualify for the auction and do not withdraw their shares or cancel their qualification for the auction as set forth in Section 4 – “Withdrawal Rights,” will have a stop transfer order on all of the Common Shares or Preferred Shares they have qualified for the auction, which will prevent such holders from being able to transfer such shares until the Settlement Date.

Shares transferred to the Central Depositary and tendered in the tender offer may be traded up until the beginning of the auction on the Auction Date. In order to ensure its ability to tender such Common Shares or Preferred Shares in the tender offer, the purchaser will need to allow sufficient time for its Brokerage Firm to tender on its behalf no later than the Share Expiration Time on the Expiration Date, in the manner described in this offer to purchase.

Having qualified for the auction, the holder of Common Shares or Preferred Shares that wishes to tender his or her shares in the tender offer must, by means of its custody agent at the Central Depositary, transfer his or her shares to portfolio 7105-6, opened in its name and kept by the Central Depositary exclusively for such purpose, by 11:00 a.m., New York City time on the Auction Date. Registered sale orders, the corresponding Common Shares or Preferred Shares of which have not been deposited at the portfolio kept by the Central Depositary, shall be cancelled.

After it has qualified for the auction and deposited its shares at the portfolio, the holder must instruct its Brokerage Firm to tender its Common Shares or Preferred Shares in the auction on its behalf. To tender a holder’s Common Shares or Preferred Shares, the holder’s Brokerage Firm must, no later than 11:00 a.m., New York City time, on the Auction Date, present a sell order on behalf of the holder through the São Paulo Stock Exchange’s Megabolsa electronic trading system using the codes set forth in Section 2 – “Acceptance for Payment and Payment for Shares.”

The purchase price in the tender offer will be R$26.64 per Common Share and Preferred Share (for reference, equivalent to approximately U.S.$ per ADS based on the average of the buy and sell U.S. dollar-Brazilian real exchange rates indicated under “transaction PTAX 800, option 5” published by the Central Bank of Brazil through the SISBACEN system at 7:00 p.m., Brasilia time, on , 2012, which was U.S.$1.00 = R$ ), in each case plus interest at the CDI Rate (for reference, approximately % on , 2012), calculated pro rata from June 8, 2012 to the Settlement Date, properly and timely tendered and not properly withdrawn. The Offerors will pay this purchase price in cash, net of the stock exchange and settlement fee described herein, any applicable brokerage fees or commissions and applicable withholding taxes, upon the terms and subject to the conditions described in this offer to purchase and the related ADS letter of transmittal, for Common Shares and Preferred Shares purchased in the auction on the third Brazilian business day after the auction, in accordance with the rules established by the Central Depositary. Each shareholder that sells Common Shares or Preferred Shares directly must pay a combined fee to the São Paulo Stock Exchange and the Central Depositary in an amount equal to 0.035% of the purchase price received by that holder. Shareholders must pay any fee or commission charged by their Brokerage Firm. See INTRODUCTION.

If a holder of ADSs wishes to participate in the tender offer, the holder may tender the Preferred Shares underlying its ADSs through The Bank of New York Mellon, as receiving agent, prior to the ADS Expiration Time on the Expiration Date, in accordance with the instructions set forth below and in the accompanying ADS letter of transmittal. The receiving agent will surrender those ADSs to the ADS depositary and instruct a Brokerage Firm to tender the Preferred Shares underlying the ADSs in the auction. There is no separate tender offer being made in the United States to acquire ADSs.

Any holder of ADSs that wishes to tender the Preferred Shares underlying its ADSs through the receiving agent must either:

Brokers and other securities intermediaries impose cutoff dates and times to give instructions to deliver ADSs and tender the underlying Preferred Shares that will be earlier than the ADS Expiration Time on the Expiration Date. Beneficial owners holding through brokers and other securities intermediaries should contact their brokers and other securities intermediaries to determine the cutoff date and time applicable to them.

Registered holders of uncertificated ADSs will not deliver ADRs evidencing their ADSs but must still deliver a signed ADS letter of transmittal and any other documents required by the ADS letter of transmittal.

Delivery of documents to DTC will not constitute delivery to the receiving agent.

The ADS letter of transmittal accompanying this offer to purchase is to be properly completed and duly executed by ADS holders registered in the books of the ADS depositary. An agent’s message (as defined below) must be used if delivery of ADSs is to be made by book-entry transfer to an account maintained by the receiving agent at DTC pursuant to the procedures for book-entry transfer. ADRs evidencing ADSs together with a

properly completed and duly executed ADS letter of transmittal (or an originally signed facsimile thereof) with any required signature guarantees and any other documents required by the receiving agent must be delivered to the receiving agent at one of its addresses set forth in the ADS letter of transmittal, or, in the case of a book-entry transfer through DTC, an agent’s message must be transmitted to the receiving agent, in each case to be received prior to the ADS Expiration Time on the Expiration Date. If ADRs are forwarded to the receiving agent in multiple deliveries, a properly completed and duly executed ADS letter of transmittal (or an originally signed facsimile thereof) must accompany each such delivery.

Except as otherwise provided below, all signatures on the ADS letter of transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a participant in good standing in the Securities Transfer Agents Medallion Program (STAMP), the New York Stock Exchange Medallion Signature Program (MSP), or the Stock Exchanges Medallion Program (SEMP) or any other “eligible guarantor institution” (as defined in Rule 17Ad-15 under the Exchange Act) (collectively, “Eligible Institutions”). Signatures on the ADS letter of transmittal need not be guaranteed (1) if the ADS letter of transmittal is signed by the registered holder of the ADSs representing the Preferred Shares tendered with it and that holder has not completed either Box 2: “Special Issuance Instructions” or Box 3: “Special Delivery Instructions” on the ADS letter of transmittal, or (2) if the Preferred Shares represented by ADSs are tendered for the account of an Eligible Institution.

The term “agent’s message” means a message transmitted by means of DTC to, and received by, the receiving agent and forming a part of a book-entry confirmation that states that DTC has received an express acknowledgment from the DTC participant tendering ADSs that are the subject of such book-entry confirmation that such participant has received and agrees to be bound by the terms of the ADS letter of transmittal and that the purchaser may enforce such agreement against the participant.

The method of delivery of letters of transmittal, ADRs and any other required documents is at the sole option and risk of the tendering holders of ADSs. Letters of transmittal, ADRs and any other required documents will be deemed delivered only when actually received by the receiving agent. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery prior to the ADS Expiration Time on the Expiration Date.

No alternative, conditional or contingent tenders will be accepted. By executing the letter of transmittal, all tendering ADS holders waive any right to receive any notice of the acceptance of the Preferred Shares underlying their ADSs for purchase.

All properly completed and duly executed letters of transmittal, ADRs and any other required documents or, in the case of a book-entry transfer, all agent’s messages, delivered to the receiving agent by holders of ADSs will be deemed, without any further action by the receiving agent, to constitute acceptance by such holders of the tender offer with respect to the Preferred Shares represented by those ADSs, upon the terms set forth in this offer to purchase and the accompanying ADS letter of transmittal.

After purchase by us of the Preferred Shares underlying the ADSs tendered through the receiving agent and receipt by the receiving agent of payment of the consideration for those Preferred Shares, the receiving agent will pay to the applicable holders of ADSs the U.S. dollar equivalent (based on the spot market exchange rate on the date the receiving agent is notified that its Brokerage Firm has received payment in Brazilian reais, net of expenses for converting Brazilian reais to U.S. dollars) of R$26.64 per Preferred Share (for reference, equivalent to approximately U.S.$ per ADS based on the PTAX exchange rate of U.S.$1.00 = R$ on , 2012), plus interest at the CDI Rate (for reference, approximately % on , 2012), calculated pro rata from June 8, 2012 to the Settlement Date, minus (1) a fee of up to U.S.$5.00 per 100 ADSs or portion thereof for the cancellation of the ADSs representing Preferred Shares purchased in the tender offer, (2) the combined fee of 0.035% of the purchase price payable to the São Paulo Stock Exchange and the Central Depositary, as described

in Section 1 – “Terms of the Tender Offer and Expiration Date;” (3) the holder’s pro rata portion of the fee or commission charged by the receiving agent’s Brokerage Firm to tender Preferred Shares underlying ADSs on behalf of ADS holders participating in the tender offer; and (4) applicable withholding taxes. The ADS cancellation fee is payable to JPMorgan Chase Bank, as depositary under the deposit agreement governing Net’s ADS program. In addition, ADS holders must pay any taxes or governmental charges payable in connection with the cancellation of ADSs representing Preferred Shares purchased in the tender offer. ADS holders will receive the consideration for the ADSs representing Preferred Shares accepted for purchase in the tender offer in cash by check or, in the case of ADSs held through DTC, by means of delivery of funds to the account maintained at DTC by the tendering participant. Under no circumstances will interest be paid on such consideration for the ADSs regardless of any delay in making payment to holders of ADSs.

If the Preferred Shares underlying a holder’s ADSs are not accepted for purchase for any reason or a tender is withdrawn, those ADSs will be returned as promptly as practicable after the expiration of the tender offer or the proper withdrawal of the Preferred Shares underlying the ADSs, as applicable, or, in the case of ADSs transferred through DTC, the unpurchased ADSs will be credited as promptly as practicable to the account at DTC from which they were transferred.

A tender of Preferred Shares underlying ADSs through the receiving agent can be made only by the holder of record of the ADSs or a securities intermediary holding ADSs through DTC. Any beneficial owner of ADSs that wishes to participate in the tender offer must instruct the broker or other securities intermediary through which those ADSs are held to tender the ADSs by completing, executing, detaching and returning to that broker or other securities intermediary the accompanying instruction form. If a beneficial owner authorizes the tender of the Preferred Shares underlying its ADSs, all the Preferred Shares underlying the ADSs will be tendered unless otherwise specified in the instruction form. The instruction form must be forwarded to that broker or other securities intermediary in ample time to permit that securities intermediary to tender the Preferred Shares underlying the ADSs through the receiving agent on the beneficial owner’s behalf before the ADS Expiration Time on the Expiration Date.

As an alternative to tendering Preferred Shares underlying ADSs through the receiving agent, an ADS holder may also surrender its ADSs, withdraw the Preferred Shares underlying the ADSs from the ADS program and participate directly in the tender offer as a holder of Preferred Shares. If a holder of ADSs wishes to participate directly in the tender offer in this manner, that ADS holder must first:

If an ADS holder surrenders ADSs and receives the Preferred Shares underlying the ADSs, the Preferred Shares so received will need to be registered at the Central Depositary and the holder will need to obtain its own foreign investor registration under Resolution No. 2,689/00 of the National Monetary Council. See Section 10 – “Certain Legal and Regulatory Matters – Registering Under Resolution No. 2,689/00” for more information on obtaining a foreign investor registration.

After the holder appoints a Brazilian representative for purposes of Resolution No. 2,689/00 of the National Monetary Council, the holder must make arrangements for that representative to tender the Preferred Shares on its behalf in the same manner as any other direct holder of Preferred Shares registered at the São Paulo Stock

Exchange’s Clearing and Settlement Chamber. The holder will need to take these steps in sufficient time to allow its Brazilian representative to participate in the tender offer on its behalf no later than the Share Expiration Time on the Expiration Date, in the manner described in – “Direct Holders of Common Shares and Preferred Shares.”

Tendering the Preferred Shares underlying the ADSs and participating directly in the tender offer enables holders to withdraw from the tender offer until the beginning of the auction on the Auction Date, as described in Section 4 – “Withdrawal Rights.” However, withdrawal of the Preferred Shares underlying the ADSs from the ADS program requires payment of the ADS cancellation fee described above. In addition, upon the redeposit of Preferred Shares into Net’s ADS program, an additional fee of up to U.S.$5.00 per 100 ADSs or portion thereof will be payable to the depositary.

There will be no guaranteed delivery process available to tender Common Shares or Preferred Shares, including Preferred Shares represented by ADSs.

All questions as to the form of documents and the validity, form, eligibility (including time of receipt) and acceptance of any tender of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) will be determined by us in our sole discretion, which determination shall be final and binding on all parties. We reserve the absolute right to reject any and all tenders of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) determined by us not to be in proper form. We also reserve the absolute right to waive any defect or irregularity in the tender of any Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) of any particular holder, whether or not similar defects or irregularities are waived in the case of other holders. No tender of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) will be deemed to have been validly made until all defects and irregularities have been cured or waived. Neither we nor any of our affiliates or assigns nor any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Our interpretation of the terms of the tender offer will be final and binding.

The tender of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) pursuant to any of the procedures described above will constitute the tendering holder’s acceptance of the terms of the tender offer, as well as the tendering holder’s representation and warranty to us that:

Holders that have tendered their Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) may withdraw from the tender offer, but they may do so only as described in this section. Holders may withdraw any or all of the securities they have tendered as described in this section. For a withdrawal to be effective, the Brokerage Firm that has been instructed to tender Common Shares or Preferred Shares in the auction, as described in Section 2 – “Acceptance for Payment and Payment for Shares,” including the receiving agent’s Brokerage Firm, must withdraw the order to sell those Common Shares or Preferred Shares before the beginning of the auction on the Auction Date. Any tender of Common Shares or Preferred Shares will be irrevocable after that time. If a shareholder wishes to withdraw the tender of its Common Shares or Preferred Shares, it is the responsibility of the shareholder to ensure that the Brokerage Firm that has been instructed to tender its Common Shares or Preferred Shares receives instructions to withdraw the tender of those Common Shares or Preferred Shares before that time. An ADS holder must submit a written notice of withdrawal to the receiving agent prior to the ADS Expiration Time on the Expiration Date. In order to withdraw from the tender offer, shareholders and ADS holders should follow the instructions below.

If a shareholder holds Common Shares or Preferred Shares directly, the shareholder or its representative in Brazil must contact the Brokerage Firm that it has instructed to sell Common Shares or Preferred Shares in the auction on its behalf in sufficient time to enable the Brokerage Firm to withdraw the order to sell any or all of those Common Shares or Preferred Shares before the beginning of the auction on the Auction Date and must provide any documentation required by the Brokerage Firm. Shareholders that wish to withdraw from the tender offer are strongly advised to contact their Brokerage Firms well before the beginning of the auction.

If an ADS holder is participating in the tender offer by tendering the Preferred Shares underlying its ADSs through the receiving agent, its originally signed written notice of withdrawal must be received by the receiving agent prior to the ADS Expiration Time on the Expiration Date at one of the addresses below.

As promptly as practicable upon valid withdrawal, the ADRs evidencing the relevant ADSs will be returned or, in the case of a book-entry transfer of ADSs, the ADSs representing the relevant Preferred Shares will be credited into the DTC account from which they were transferred. Preferred Shares represented by properly withdrawn ADSs may be re-tendered by following the procedures described in Section 3 – “Procedures for Participating in the Tender Offer” at any time prior to the ADS Expiration Time on the Expiration Date.

Please note that any ADS holder that wishes to be able to withdraw up until the beginning of the auction on the Auction Date must surrender its ADSs to JPMorgan Chase Bank, as ADS depositary, withdraw the Preferred Shares underlying the ADSs from the ADS program and participate directly in the tender offer as a holder of Preferred Shares, allowing sufficient time for the completion of all required steps described in this offer to purchase before the Share Expiration Time on the Expiration Date. See Section 3 – “Procedures for Participating in the Tender Offer – Holders of ADSs – Direct Participation in the Tender Offer.”

In accordance with Section 14(d)(5) of the Exchange Act, a shareholder that has tendered Common Shares or Preferred Shares may withdraw any or all of those Common Shares or Preferred Shares at any time after 60 days from date hereof if the auction has not occurred before that date, by communicating its request to withdraw its Common Shares or Preferred Shares in the manner described above.

Even if we extend the tender offer or we are delayed in accepting, or unable to accept, Common Shares or Preferred Shares for purchase pursuant to the tender offer for any reason, elections to tender may be withdrawn only as described herein. Any such delay will be made by an extension of the tender offer to the extent required by law. See Section 1 – “Terms of the Tender Offer and Expiration Date.”

All questions as to the form and validity (including time of receipt) of any notice of withdrawal will be determined by us, in our sole discretion, and our determination will be final and binding. Neither we nor any of our affiliates or assigns nor any other person will be under any duty to give any notification of any defects or irregularities in any withdrawal or incur any liability for failure to give any such notification.

Withdrawals of tendered Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) may not be rescinded. Any Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) properly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the tender offer. However, holders of Common Shares or Preferred Shares that have properly withdrawn tendered Common Shares or Preferred Shares may re-tender those Common Shares or Preferred Shares at any time before the Share Expiration Time on the Expiration Date. ADS holders that have properly withdrawn the Preferred Shares represented by their ADSs from the tender offer may re-tender through the receiving agent at any time before the ADS Expiration Time on the Expiration Date. See Section 3 – “Procedures for Participating in the Tender Offer.”

The total amount of funds that we must provide to purchase all of the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) not already owned by us or our affiliates, which is the maximum number of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) subject to the tender offer, before fees and expenses, is estimated to be approximately R$479,510,863 million (for reference, equivalent to approximately U.S.$ million based on the PTAX exchange rate of U.S.$1.00 = R$ on , 2012) based on an offer price of R$26.64 per Common Share and per Preferred Share. We plan to acquire the tendered Common Shares and Preferred Shares, and to cover any related fees and expenses through our available cash resources. Itaú BBA guarantees the settlement of the tender offer, except with respect to a competing offer from a third party, as described in Section 2 – “Acceptance for Payment and Payment for Shares.”

The following discussion summarizes the material Brazilian tax consequences of the disposition of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) by a holder not deemed to be domiciled in Brazil for Brazilian tax purposes (for purposes of this subsection – “Brazilian Tax Consequences,” a “non-Brazilian holder”), including a disposition of Common Shares and Preferred Shares

(including Preferred Shares represented by ADSs) in the tender offer. This discussion does not address all the Brazilian tax considerations that may be applicable to any particular non-Brazilian holder, and each non-Brazilian holder should consult its own tax advisor about the Brazilian tax consequences of disposing of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) in the tender offer.

According to article 26 of Brazilian Law No. 10,833, enacted on December 29, 2003, the disposition of assets located in Brazil by a non-resident to either a Brazilian resident or a non-resident may be subject to taxation in Brazil, regardless of whether the disposition occurs outside or within Brazil.

Gains realized outside Brazil or in Brazil by a non-Brazilian holder on disposition of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) of Net may be taxed at 20% or 15%, or be free of Brazilian tax, depending on the circumstances:

The “gain realized” as a result of a transaction on a Brazilian stock exchange is the difference between the amount in Brazilian reais realized on the sale or exchange and the acquisition cost measured in Brazilian reais, without any correction for inflation. Despite the fact that the legislation is not entirely clear, the acquisition cost of Common Shares or Preferred Shares registered as an investment with the Central Bank has been historically calculated on the basis of the foreign currency amount registered with the Central Bank translated into Brazilian reais at the commercial market rate on the date of the sale or exchange.

There are no Brazilian stamp, issue, registration or similar taxes or duties payable by holders of Common Shares or Preferred Shares.

A financial transaction tax (“IOF tax”) may be imposed on a variety of transactions, including the conversion of Brazilian currency into foreign currency (e.g., for purposes of paying dividends and interest). The IOF tax rate on such conversions is currently 0%, for investments registered with the Central Bank pursuant to

Resolution No. 2,689/00 of the National Monetary Council, or 0.38%, for investments that are not registered as such but the minister of finance has the legal power to increase the rate to a maximum of 25%. Any increase would be applicable only prospectively. The IOF tax may also be levied on transactions involving bonds or securities (“IOF/Títulos tax”) even if the transactions are effected on Brazilian stock, futures or commodities exchanges. The rate of the IOF/Títulos tax with respect to Common Shares and Preferred Shares is currently 0%. The minister of finance, however, has the legal power to increase the rate to a maximum of 1.5% of the amount of the taxed transaction per each day of the investor’s holding period, but only to the extent of gain realized on the transaction and only on a prospective basis.

The following is a summary of the material U.S. federal income tax consequences of the tender offer with respect to the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs). As used in this subsection, – “United States Federal Income Tax Consequences,” the term “Preferred Shares” refers to both Preferred Shares and the ADSs. The discussion set forth below is only applicable to U.S. Holders (as defined below) that tender Common Shares or Preferred Shares in the tender offer. This discussion addresses only beneficial owners of Common Shares and Preferred Shares that hold such shares as capital assets.

The summary does not purport to be a comprehensive description of all of the tax considerations that may be relevant to any particular investor, including tax considerations that arise from rules of general application to all taxpayers or certain aspects of U.S. federal income taxation that may be applicable to a holder subject to special treatment under the Internal Revenue Code of 1986, as amended (the “Code”) (including, but not limited to, banks or other financial institutions, regulated investment companies, holders that own or are treated as owning 10% or more of any class of stock of Net, entities that are treated for U.S. federal income tax purposes as partnerships or other pass-through entities, tax-exempt organizations, insurance companies, brokers or dealers in securities or foreign currency, traders in securities who elect to mark their securities to market for U.S. federal income tax purposes, holders that have a functional currency other than the U.S. dollar, and holders that acquired shares pursuant to the exercise of an employee stock option or otherwise as compensation). In addition, the discussion does not address the state, local or foreign tax consequences (or other tax consequences such as estate or gift tax consequences) of the tender offer. The discussion below is based upon the provisions of the Code and U.S. Treasury regulations, rulings and decisions thereunder as of the date hereof, and such authorities may be repealed, revoked or modified (with possible retroactive effect) so as to result in U.S. federal income tax consequences different from those discussed below.

Holders should consult their own tax advisors concerning the tax consequences of the tender offer in light of their particular situations, as well as any consequences arising under the laws of any other taxing jurisdiction.

As used in this subsection – “United States Federal Income Tax Consequences,” the term “U.S. Holder” means a beneficial holder of Common Shares or Preferred Shares that is (1) an individual citizen or resident of the United States, (2) a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state thereof or the District of Columbia, or (3) otherwise subject to U.S. federal income taxation on a net income basis in respect of the Common Shares or Preferred Shares. This summary does not apply to holders of Common Shares or Preferred Shares who are not U.S. Holders. Non-U.S. Holders should consult their own tax advisors regarding the U.S. federal income tax consequences and any applicable state, local and non-U.S. tax consequences of the tender offer.

The receipt of cash in exchange for Common Shares or Preferred Shares pursuant to the tender offer will be a taxable transaction for U.S. federal income tax purposes. A U.S. Holder of Common Shares or Preferred Shares will generally recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference

between the amount of cash received and the U.S. Holder’s tax basis in the Common Shares or Preferred Shares exchanged. Such gain or loss generally will be capital gain or loss. Capital gains of individuals derived with respect to capital assets held for more than one year at the time the Common Shares or Preferred Shares are exchanged are subject to reduced rates of taxation. The deductibility of capital losses is subject to limitations.

The amount of any cash paid to a U.S. Holder (pursuant to the tender offer) in Brazilian reais will equal the U.S. dollar value of the Brazilian reais received, calculated by reference to the exchange rate in effect on the date the cash is received by the U.S. Holder, regardless of whether the Brazilian reais are converted into U.S. dollars. If the Brazilian reais received are not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a basis in the Brazilian reais equal to their U.S. dollar value on the date of receipt, and any gain or loss realized on a subsequent conversion or other disposition of the Brazilian reais will generally be treated as ordinary income or loss.

Brazilian taxes that may be imposed on a U.S. Holder upon gain realized pursuant to the tender offer will generally be treated as foreign income taxes eligible for credit against a U.S. Holder’s federal income tax liability or for deduction in computing such U.S. Holder’s taxable income. Any gain or loss generated by the sale of the Common Shares or Preferred Shares by a U.S. Holder will generally be treated as U.S. source gain or loss. Accordingly, a U.S. Holder may not be able to use the foreign tax credit arising from any Brazilian tax imposed on the disposition of the Common Shares or Preferred Shares unless such credit can be applied (subject to applicable limitations) against tax due on other income treated as derived from foreign sources in the appropriate income category. The calculation and availability of foreign tax credits and, in the case of a U.S. Holder that elects to deduct foreign taxes, the availability of deductions, involves the application of complex rules that depend on a U.S. Holder’s particular circumstances. U.S. Holders should consult with their own tax advisors with regard to the availability of foreign tax credits and the application of the foreign tax credit limitations in light of their particular situations.

In general, information reporting requirements will apply to the cash payments received pursuant to the tender offer that are paid within the United States (and in certain cases, outside of the United States) to U.S. Holders other than certain exempt recipients (such as corporations), and backup withholding (currently at a rate of 28%, but scheduled to increase to a rate of 31% as of January 1, 2013) may apply to such amounts if a U.S. Holder fails to provide an accurate taxpayer identification number and make any other required certification or otherwise establish an exemption. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a refund or a credit against the U.S. Holder’s U.S. federal income tax liability so long as the required information is provided to the IRS.

Backup withholding and information reporting will not generally apply to the cash payments made pursuant to the tender offer that are received by a non-U.S. Holder if such holder certifies under penalties of perjury that such holder is a non-U.S. person for U.S. federal income tax purposes.

The name, business address, citizenship, present principal occupation and employment history for the past five years of each of the directors and executive officers of Embratel, Embrapar and GB are set forth on Schedule 1 to this Offer to Purchase.

None of Embratel, Embrapar and GB or, to the knowledge of Embratel, Embrapar or GB after reasonable inquiry, any of the persons listed in Schedule 1, has during the last five years (a) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) been a party to any judicial or administrative proceeding (except for matters that were dismissed without sanction or settlement) that resulted in a judgment, decree or final order enjoining the person from future violations of, or prohibiting activities subject to, U.S. federal or state securities laws or a finding of any violation of U.S. federal or state securities laws.

Except as set forth elsewhere in this Offer to Purchase or in Schedule 1: (a) none of Embratel, Embrapar and GB or, to the knowledge of Embratel, Embrapar or GB after reasonable inquiry, any of the persons listed in Schedule 1 or any associate or majority-owned subsidiary of Embratel, Embrapar or GB or any of the persons so listed, beneficially owns or has a right to acquire any Shares or any other equity securities of Net, (b) none of Embratel, Embrapar and GB or, to the knowledge of Embratel, Embrapar or GB after reasonable inquiry, any of the persons referred to in clause (a) above or any of their executive officers, directors, affiliates or subsidiaries has effected any transaction in Shares or any other equity securities of Net during the past 60 days, (c) none of Embratel, Embrapar, GB , their subsidiaries or, to the knowledge of Embratel, Embrapar or GB after reasonable inquiry, any of the persons listed in Schedule 1, has any agreement, arrangement, or understanding, whether or not legally enforceable, with any other person with respect to any securities of Net (including, but not limited to, any agreement, arrangement, or understanding concerning the transfer or the voting of any such securities, joint ventures, loan or option arrangements, puts or calls, guarantees of loans, guarantees against loss or the giving or withholding of proxies, consents or authorizations), (d) in the past two years, except as set forth elsewhere in this document, there have been no transactions that would require reporting under the rules and regulations of the SEC between any of Embratel, Embrapar, GB their subsidiaries or, to the knowledge of Embratel, Embrapar or GB after reasonable inquiry, any of the persons listed in Schedule 1, on the one hand, and Net or any of its executive officers, directors or affiliates, on the other hand, and (e) in the past two years, there have been no negotiations, transactions or material contacts between any of Embratel, Embrapar, GB , their subsidiaries or, to the knowledge of Embratel, Embrapar or GB after reasonable inquiry, any of the persons listed in Schedule 1, on the one hand, and Net or any of its affiliates, on the other hand, concerning a merger, consolidation or acquisition, a tender offer or other acquisition of Net’s securities, an election of Net’s directors or a sale or other transfer of a material amount of assets of Net.

We do not believe that the financial condition of Embratel, Embrapar and GB is relevant to a decision by a holder of Common Shares, Preferred Shares or ADSs to tender Common Shares or Preferred Shares (including

Preferred Shares represented by ADSs) in the tender offer because (a) the tender offer is being made for all Common Shares and Preferred Shares, (b) the tender offer is solely for cash and (c) the tender offer is not subject to any financing condition.

Neither Embratel nor GB is subject to the informational requirements of the CVM, the São Paulo Stock Exchange or of the SEC.

As of July 31, 2012, the Slim Family, through their beneficial ownership held by a trust and another entity and their direct ownership of shares, may be deemed to beneficially own approximately 65.6% of the outstanding voting securities of América Móvil, our parent company. As a result, members of the Slim Family may also be deemed to be beneficial owners of the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) owned by us. Because they have the effective power to designate a majority of the members of América Móvil’s board of directors and to determine the outcome of other actions requiring a vote, the Slim Family may be deemed to control América Móvil.

The name, business address and telephone number and business experience of each member of the Slim Family are set forth in Schedule 1 hereto.

We are not aware of (1) any license or other regulatory permit that appears to be material to the business of Embratel, Embrapar, GB or any of their subsidiaries that might be adversely affected by the purchase of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) by us in the tender offer or (2) except for the registration of the tender offer with the CVM, any approval or other action by any domestic (federal or state) or foreign governmental authority that would be required before the purchase of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) by us in the tender offer. Should any such approval or other action be required, it is our present intention to seek that approval or action. We do not currently intend, however, to delay the purchase of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) pursuant to the tender offer pending the outcome of any such action or the receipt of any such approval. However, we may be required to delay the acceptance for payment of or payment for Common Shares or Preferred Shares tendered in the tender offer until the outcome of that process, if necessary, is

known. Any such approval or other action, if needed, might not be obtained or might be obtained only with substantial cost or conditions, and adverse consequences to our business, Net or our respective subsidiaries might result.

The purchase of the Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) by us pursuant to the tender offer is not subject to the approval of the Brazilian or U.S. antitrust authorities.

Because we may be deemed to be an affiliate of Net for the purposes of Rule 13e-3 under the Exchange Act, this tender offer constitutes a “going private” transaction pursuant to Rule 13e-3. Rule 13e-3 requires, among other things, that certain financial information concerning Net and certain information relating to the fairness of the offer price be filed with the SEC. We have provided such information in this offer to purchase and in the combined Schedule TO and Schedule 13E-3, together with the exhibits thereto, filed with the SEC pursuant to Rule 14d-3 under the Exchange Act.

This offer qualifies as a “Tier II” offer in accordance with Rule 14d-1(d) under the Exchange Act and is, as a result, exempt from certain provisions of otherwise applicable U.S. statutes and rules relating to tender offers. U.S. and Brazilian law and practice relating to tender offers are inconsistent in a number of ways. We intend to rely on the Tier II exemption from Rule 14e-1(c) on prompt payment and from Rule 14e-1(d) on the procedures for giving notices of any extensions of the length of the tender offer, where we will follow Brazilian law and practice.

The right to convert dividend payments and proceeds from the sale of Brazilian securities into foreign currency and to remit those amounts outside Brazil is subject to restrictions under foreign investment regulations, which generally require, among other things, the electronic registration of the relevant investment with the Central Bank. JPMorgan Chase Bank, as ADS depositary, holds an electronic registration for the Preferred Shares underlying the ADSs of Net.

Any ADS holder that wishes to participate directly in the tender offer, as described in Section 3 – “Procedures for Participating in the Tender Offer – Holders of ADSs – Direct Participation in the Tender Offer,” rather than tender Preferred Shares underlying ADSs through the receiving agent, must withdraw the Preferred Shares it wishes to tender from Net’s ADS program. That holder must then obtain its own electronic registration by registering its investment in the Preferred Shares as a foreign portfolio investment under Resolution No. 2,689/00 of the National Monetary Council.

Under Resolution No. 2,689/00 of the National Monetary Council, foreign investors may invest in almost all financial assets and engage in almost all transactions available in the Brazilian financial and capital markets, provided that certain requirements are met. Resolution No. 2,689/00 of the National Monetary Council affords favorable tax treatment to foreign portfolio investors that are not residents of a “low tax” jurisdiction as defined by Brazilian tax laws (meaning a country that does not impose taxes, a country where the maximum income tax rate is lower than 20% or a country that restricts the disclosure of shareholder composition or the ownership of investments). See Section 6 – “Certain U.S. Federal Income and Brazilian Tax Consequences.” Nevertheless, trading of securities is restricted to transactions carried out on the stock exchanges or organized over-the-counter markets licensed by the CVM.

A foreign portfolio investor under Resolution No. 2,689/00 of the National Monetary Council must:

Securities and other financial assets held by foreign investors pursuant to Resolution No. 2,689/00 of the National Monetary Council must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or the CVM.

If a holder of ADSs wishes to withdraw the Preferred Shares underlying those ADSs and convert its investment into a foreign portfolio investment under Resolution No. 2,689/00 of the National Monetary Council, it should begin the process of obtaining its own foreign investor registration in advance of surrendering the ADSs to JPMorgan Chase Bank, as ADS depositary, and withdrawing the Preferred Shares from the ADS program. If the holder of ADSs does not timely complete this process, the custodian for the depositary will neither effect the exchange nor deliver the Preferred Shares underlying the ADSs, and will instruct the depositary to cancel the exchange and return the ADSs to the holder.

We have retained BTG Pactual to prepare a valuation report, as required under Brazilian regulations in connection with the tender offer. Upon delivery of the Valuation Report by BTG Pactual to us, we paid BTG Pactual a fee of R$664,084.12 for the preparation of its Valuation Report and reimbursed BTG Pactual R$933.93 for its reasonable travel and other out-of-pocket expenses incurred in connection with its engagement. We have also agreed to reimburse BTG Pactual for the remainder of its expenses, including the reasonable fees and expenses of its counsel, and to indemnify BTG Pactual and its affiliates against specific liabilities and expenses arising out of its engagement. BTG Pactual has provided in the past, and may continue to provide from time to time, investment banking advice and financial advisory services to Embratel, Embrapar, GB and its affiliates (including Net). BTG Pactual and its affiliates have received and will receive customary fees for such services.

We have retained Itaú BBA and Itaú Corretora as the Brazilian intermediary institutions, the Bank of New York Mellon as the receiving agent, and D.F. King & Co., Inc., as the U.S. information agent in connection with the tender offer. Each of these entities will receive customary compensation and reimbursement for reasonable out-of-pocket expenses, as well as indemnification against certain liabilities in connection with the tender offer.

The U.S. information agent may contact holders of Common Shares, Preferred Shares and ADSs by personal interview, mail, electronic mail, telephone and other methods of electronic communication and may request brokers and other securities intermediaries to forward the tender offer materials to beneficial holders of Common Shares, Preferred Shares and ADSs to the extent permitted by applicable law.

Except as set forth above, we have not retained and will not pay any fees or commissions to any broker or dealer or other person for recommending or soliciting tenders of Common Shares and Preferred Shares (including Preferred Shares represented by ADSs) pursuant to the tender offer.

Brokers and other securities intermediaries will be reimbursed by us for customary handling and mailing expenses incurred by them in forwarding material to their customers.

Although the tender offer is open to all holders of Common Shares, Preferred Shares and ADSs, this offer document is intended solely for holders of Common Shares and Preferred Shares that are U.S. residents (within the meaning of Rule 14d-1(d) under the Exchange Act) and holders of ADSs representing Preferred Shares. Holders of Common Shares or Preferred Shares that are not U.S. residents may not use this offer document. Separate offer materials referred to as an Edital in Portuguese have been published in Brazil, as required by Brazilian law. In addition, a short circular primarily corresponding to the Edital for use by holders of Preferred Shares listed on the Mercado de Valores Latinoamericanos is being published in Spanish concurrently in Spain as required under applicable Spanish law. We are not aware of any jurisdiction where the making of the tender offer or the election to tender Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) in connection therewith would not be in compliance with the laws of that jurisdiction. If we become aware of any jurisdiction in which the making of the tender offer or the election to tender Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) in connection therewith would not be in compliance with applicable law, we will make a good faith effort to comply with any such law. If, after making such good faith effort, we cannot comply with any such law, the tender offer will not be made to (nor will elections to tender Common Shares or Preferred Shares be accepted from or on behalf of) the holders of Common Shares or Preferred Shares (including Preferred Shares represented by ADSs) in that jurisdiction. In any jurisdiction where the securities, blue sky or other laws require the tender offer to be made by a licensed broker or dealer, the tender offer will be deemed to be made on our behalf by one or more registered brokers or dealers licensed under the laws of such jurisdiction.

No person has been authorized to give any information or make any representation on our behalf not contained in this offer to purchase, and if given or made, such information or representation must not be relied upon as having been authorized.

We have filed with the SEC a combined Schedule TO and Schedule 13E-3, together with exhibits, furnishing certain additional information with respect to the tender offer. You may read and copy the combined Schedule TO and Schedule 13E-3 and any amendments thereto, including exhibits, at the SEC’s public reference room at 100 F Street, N.E., Washington, D.C. 20549. You may obtain information on the operation of the public reference room by calling the SEC at 1-800-SEC-0330. The SEC maintains an Internet site at http://www.sec.gov that contains reports and other information regarding issuers that file electronically with the SEC.

You should rely only on the information incorporated by reference or provided in this offer to purchase or any supplement to this offer to purchase. We have not authorized anyone to provide you with different information. The date of this offer to purchase is , 2012. You should not assume that the information in this offer to purchase is accurate as of any date other than that date, regardless of the time such offer to purchase is made available to you.
