c) The STFC concession agreement

The Company is a concessionaire of the fixed-switch telephone service (STFC) to render local and domestic long-distance calls originated in Region 3, which comprises the State of São Paulo, in Sectors 31, 32 and 34, established in the General Concession Plan (PGO).

The current Concession Agreement’s renewal, dated December 22, 2005, in force since January 1, 2006, awarded as an onerous title, will be valid until December 31, 2025. However, the agreement can be reviewed on December 31, 2010, 2015 and 2020. Such condition allows ANATEL to set up new requirements and goals for universalization and quality of telecommunication services, according to the conditions in force at that moment.

The Concession Agreement establishes that all assets owned by the Company and which are indispensable to the provision of the services described on such agreement are considered reversible assets and are deemed to be part of the concession assets. These assets will be automatically returned to ANATEL upon expiration of the concession agreement, according to the regulation in force at that moment. In September 30, 2010, the net book value of reversible assets is estimated at R$6,197,787 (R$6,954,479 on December 31, 2009), comprised of switching and transmission equipment and public use terminals, external network equipment, energy equipment and system and operation support equipment.

Under the concession agreement, every two years, during the contractual term of twenty years, the Company shall pay a renewal charge of 2% (two percent) of its prior-year STFC revenue, net of taxes and social contributions levied thereon. The next payment will take place in 2011 based on 2010 revenues.

2. Corporate events in 2009

a) Corporate restructuring involving A.Telecom S.A.:

By resolution of the General Shareholders’ Meeting held on December 30, 2009, A.Telecom was split off, and its split-off portion was later merged into the Company.

3. Presentation of consolidated quarterly information

The consolidated quarterly information (ITR) as of September 30, 2010 is presented by the Company in accordance with the International Financial Reporting Standards (IFRS) issued by IASB (see Note 4), and with the accounting practices adopted in Brazil, which include the Corporate Law provisions set forth in Law No. 6404/76, amended by Laws No. 11638/07 and No. 11941/09, and the accounting pronouncements issued by Brazilian Financial Accounting Standards Board (CPC) approved by Brazilian Securities and Exchange Commission (CVM).

Notes to the consolidated quarterly information (Continued) Nine months period ended September 30, 2010 (In thousands of reais – R$) (A free translation of the original report issued in Portuguese)

3. Presentation of consolidated quarterly information (Continued)

consolidated information as of September 30, 2009 and the information corresponding to the annual consolidated financial statements as of December 31, 2009 were adjusted and are presented for comparability purposes using the same criterion.

Assets and liabilities are classified as “current” when their realization or settlement is likely to occur within the next twelve months. Otherwise, they are classified as noncurrent.

Accounting estimates are considered for the quarterly information preparation process. Such estimates are based on objective and subjective factors according to Management’s judgment for the appropriate amounts to be recorded in the financial statements.

Transactions, which involve estimates mentioned above, may result in different amounts when realized in subsequent periods due to inaccurate results regarding the estimate process. The Company revises its estimations and assumptions periodically.

In consolidation, all assets, liabilities, revenues and expenses resulting from intercompany transactions and equity holdings between the company and its subsidiaries have been eliminated.

This ITR was prepared based on accounting principles, practices and criteria that are consistent with those adopted in the preparation of the financial statements for the last financial year, supplemented with the accounting practices described in Note 4.2, for purposes of full compliance with IFRS. This ITR should be analyzed together with such financial statements.

4. First-time adoption of IFRS

The preparation of consolidated quarterly information under IFRS requires certain modifications to the presentation and assessment that were being applied until December 31, 2009, as some IFRS principles and requirements differ substantially from the accounting practices adopted until then in Brazil.

Adjustment of the consolidated quarterly information to the international accounting standards has been carried out by applying IFRS 1 – First Time Adoption of International Financial Reporting Standards. The Company prepared the opening balance sheet using 1/1/2009 as the transition date (base date 12/31/2008).

4. First-time adoption of IFRS (Continued)

4.1 Exemptions and exceptions applied for first-time adoption of IFRS in the opening balance sheet

IFRS 1 provides for certain elective exemptions for retroactive adoption of IFRS in the opening balance sheet. In this regard, the options selected by the Company on the transition date are as follows:

IFRS 3 – Business combinations

The Company has elected to apply IFRS 3, Business Combinations, prospectively from the transition date. Therefore, business combinations occurring prior to January 1, 2009 were not restated. As such, the goodwill balance in Intangible Assets reflects the net balance presented in accordance with accounting practices adopted in Brazil at December 31, 2008.

IAS 16 – Fair value or revaluation of property, plant and equipment as acquisition cost

The Company has elected not to restate its fixed and intangible assets at their fair value, maintaining them at the respective acquisition cost carried out under accounting practices adopted in Brazil at December 31, 2008.

Exemptions of mandatory adoption according to IFRS 1 are not applicable to the Company.

The reconciliation of (i) consolidated shareholders’ equity as of January 1, September 30 and December 31, 2009, (ii) net income and (iii) comprehensive income as of September 30, 2009, as well as a brief description of the major differences between accounting practices adopted in Brazil until December 31, 2009 and IFRS are presented below:

4. First-time adoption of IFRS (Continued)

4.2 Major differences that impacted the financial statements on the transition date and on 12/31/2009

a) Business combinations

In connection with transactions that involve business combinations, the Company elected not to apply IFRS 3 – Business Combinations requirements retroactively, maintaining the same accounting treatment applied on the previous GAAP until 12/31/2008. From 1/1/2009, no operations involving business combinations were conducted.

b) Revenue recognition

According to IAS 18 - Revenue, which addresses revenue recognition, revenues from services rendered must be recognized according to the period in which the service is rendered. According to BRGAAP, revenue from activation fees was recognized upon connection of the client to the network. For IFRS purposes, revenue from activation fees is deferred and recognized in income throughout the average estimated customer length relationship period. This difference in revenue recognition accounting policies resulted in the recognition of a liability (deferred revenue) in the opening balance sheet at 1/1/2009 to reflect the portion of revenue from activation fees that will be recognized in future periods.

c) Post-employment benefits

The Company maintained BRGAAP accounting policy whereby actuarial gains and losses are immediately recognized. Under BRGAAP, actuarial gains or losses were immediately recognized in P&L, whereas for IFRS purposes (IAS19 – Employee Benefits), such gains and losses are recognized in Shareholders’ equity (Other Comprehensive Income).

Concerning to overfunded pension plans, according to BRGAAP, employee benefits assets may only be recorded if there is evidence that the surplus (plan assets in excess of obligations) will be reimbursed to the sponsor, for this reason, according to plan’s characteristics, such surplus was not recognized. As per IFRS, assets from overfunded pension plans are recognized up to the probable amount that will reduce future Company’s contributions to such plans, which is why the Company has recorded the related assets.

4. First-time adoption of IFRS (Continued)

4.2 Major differences that impacted the financial statements on the transition date and on 12/31/2009 (Continued)

d) Additional proposed dividends

According to IFRIC Interpretation 17 – Distribution of Non-cash assets to owners – a dividend payable shall be recognized as liability upon effective approval by the board of directors. Previously, the result remaining in retained earnings was considered as a dividend proposed. With the new accounting practice, dividends proposed above the minimum required by the Article of Incorporation that has not been finally approved by the Ordinary General Shareholders’ Meeting must be maintained in Shareholders’ equity, under a specific account (additional dividends proposed).

e) Unclaimed dividends and interest on shareholders’ equity

Under IAS 32 – Financial Instruments: Presentation, is considered a financial liability any contractual obligation involving cash delivery. In view of this, dividends and interest on shareholders’ equity due to Company’s shareholders, after approval thereof by management, meet this definition and are therefore classified as financial instruments.

Under IAS 39 – Financial Instruments: Recognition and Measurement, if the obligation to pay a financial liability ceases to exist, its write-off shall be recognized in profit or loss. As such, the liability corresponding to dividends and interest on shareholders’ equity not claimed by shareholders within a period of three years from the date on which they became payable (Law No. 6404/76, article 287, item II, letter a) is written off and recorded in profit or loss for the year in which the liability is statute barred (see note 23). Previously, under BR GAAP, write-off of such dividends and interest on shareholders’ equity was recognized directly in equity.

f) Income taxes

Deferred income and social contribution taxes were accrued on the previously mentioned adjustments, as applicable.

4.2 Major differences that impacted the financial statements on the transition date and on 12/31/2009 (Continued)

g) Reclassifications

There are other accounting standards adopted for IFRS purposes which differ from their equivalents adopted in Brazil. However, shareholders’ equity is not affected by these differences, but do affect presentation of balance sheet. The adjustments carried out refer to the following:

- Reclassifications of escrow deposits related to liabilities (provisions) –For BRGAAP purposes, liabilities and provision balances were presented net of the corresponding escrow deposits. For IFRS purposes, such offset is not permitted, therefore, the escrow deposits must remain in assets;

- Reclassifications of deferred income and social contribution taxes –BRGAAP required the segregation of deferred tax item in the balance sheet into current and non-current. For IFRS purposes, deferred income and social contribution tax assets and liabilities must be recorded as non-current.

Short-term investments are basically CDB (Bank Deposits Certificate), indexed under CDI (Interbank Deposit Certificate) rate variation, with quick liquidity and maintained with reputable financial institutions.

Review of property, plant and equipment useful lives

During the 1st semester of 2010, the Company detected the need of adopting new useful lives for certain categories of assets. For being a change in accounting estimates, the effects of this change will be recorded on a prospective basis as from 2010. This change represented both an extension and a reduction in useful lives in relation to those considered in 2009, causing a decrease in the depreciation expense of R$335,984 for the period ended September 30, 2010. The total estimated impact for 2010 is a decrease in the depreciation expense of R$440 million.

14. Loans and financing (Continued)

In 2007, BNDES approved a credit facility to the Company to finance investments in services and products produced domestically. The totally of these resources have been drawn and their investments are proven and accepted by BNDES. The TJLP is a specific referential rate not comparable with other market-observable rates applicable to similar repayment terms. Accordingly, at September 30, 2010 this instrument was recognized in the balance sheet at its amortized cost, which is equivalent to its fair value as of that date.

The maturity date of these debentures was September 1, 2010, but on June 7, 2010 the company made an early redemption of all outstanding debentures.

Notes to the consolidated quarterly information (Continued) Nine months period ended September 30, 2010 (In thousands of reais – R$) (A free translation of the original report issued in Portuguese)

18. Reserves for contingencies (Continued)

In the nine months period ended September 30, 2010 there were no significant changes in labor, tax and civil provisions, evaluated as “probable” loss, when compared to the previous year.

In the nine months period ended September 30, 2010 there were no significant changes in labor, tax and civil contingencies in comparison with the previous year, except for the contingency commented below:

The Public Prosecutor Office of the State of São Paulo commenced a class action claiming moral and property damages suffered by all consumers of telecommunications services from 2004 to 2009 due to the bad quality of services and failures of the communications system. The public Prosecutor Office suggested that the indemnification to be paid should be R$1 billion. The decision handed down on 4/20/2010 imposes the payment of indemnification for damages caused to all consumers who have filed a suit for such. Conversely, in the event that the number of consumers claiming to the award is not in line with the gravity of their damages, after the lapsing of one year, the judge determined that the amount of R$ 60 million be deposited in the Special Expenses Fund to Recover Natural Rights Damages (Fundo Especial de Despesa de Reparação de Interesses Difusos Lesados). It is not possible to estimate the number of consumers who will individually file suits nor the amounts claimed thereby. The Company filed an appeal on the merit of the case. The judgment effects are in abeyance. The risk of such proceeding is assessed as possible.

In addition, the State and Federal Prosecution Units have filed judicial proceedings claiming that the amounts charged on PIS and COFINS are unduly included in fixed telephone service tariffs and that amounts charged should be returned double. There are eight collective suits and several individual ones based on the same argument and claim. The decisions of these lawsuits will be affected by favorable result obtained at Supreme Court in a similar action involving a third party, justifying the absence of provision and its assessment as remote.

27

(a) Amounts resulting from the auction of share fractions after the reverse spin-off process in 2005, and TDBH acquisition process in 2006.

(b) Refer mainly to deferral of revenue from activation fee (Note 4.2.b) and inductive cards. (c) The Company has finance lease contracts for use of IT equipment.

29. Financial instruments (Continued)

Interests in other companies

The Company has direct and indirect interests in other companies resulting from the privatization process. These investments, measured at market value, consider the latest quotation available in September 30, 2010 and December 31, 2009.

The table below shows the composition of investments in other companies at market value as of September 30, 2010 and December 31, 2009:

The Company is exposed to several market risks as a result of its commercial operations, debts obtained to finance its activities and debt-related financial instruments.

The principal market risk factors that affect the Company’s business are detailed below:

a) Exchange rate risk

This risk arises from the possibility that the Company may incur losses due to exchange rate fluctuations, which would increase the financial expenses of loans denominated in foreign currency.

At September 30, 2010, 0,92% (0,65% at December 31, 2009) of the financial debt was denominated in foreign currency (US dollar). The Company has enter into derivative transactions (exchange rate hedge) with financial institutions to protect itself against exchange rate variation on its gross debt in foreign currency (R$17,644 at September 30, 2010 and R$ 23,006 at December 31, 2009).

In view of this, the indebtedness entirety (at September 30, 2010 and December 31, 2009) was covered by asset positions of exchange rate hedge with swap for CDI.

Notes to the consolidated quarterly information (Continued) Nine months period ended September 30, 2010 (In thousands of reais – R$) (A free translation of the original report issued in Portuguese)

29. Financial instruments (Continued)

There is also the exchange rate risk related to non-financial assets and liabilities in foreign currency, which can lead to a lower amount receivable or higher amount payable, depending on exchange rate variation in the period.

As from May 2010, hedge operations were contracted to minimize the exchange rate risk related to these non-financial assets and liabilities in foreign currency. This balance is subject to daily changes due to business dynamics, however, the Company aims to cover the net balance of these rights and obligations (US$29,305 payable and €33,480 receivable at September 30, 2010) to minimize the related foreign exchange risk.

b) Interest rate risk

This risk arises from the possibility of the Company to incur losses due to changes in internal interest rates, which may affect negatively derivatives in liability positions (exchange rate hedges) contracted at floating interest rates (CDI).

The debt taken out from BNDES bank is indexed by the TJLP (Long Term Interest Rate quarterly set by the National Monetary Council), which was kept at 6,0% per annum since July 2009.

The Company invests cash surplus of R$1,626,108 (R$2,266,896 at December 31, 2009), mainly in short-term financial investments (Bank Deposit Certificates) based on CDI variation, thus generating exposure to variable internal interest rate (CDI). The book value of these instruments approximates market, since they are redeemable within short term.

c) Debt acceleration risk

As of September 30, 2010, the Company had one financing agreement in force, containing restrictive clauses (covenants), typically applicable to such agreements, relating to cash generation, debt ratios and other restrictions. These covenants – which could otherwise demand payment of liabilities at an earlier time – have been fully performed by the Company, and all economic and financial indexes contractually provided have been achieved.

Risk management policy (Continued)

d) Credit risk

This risk arises from the possibility that the Company may incur losses due to the difficulty in receiving amounts billed to its customers. The credit risk on accounts receivable is dispersed. The Company constantly monitors the level of accounts receivable and limits the risk of past-due accounts, interrupting access to telephone lines in case the customer does not pay the related bills in 30 days. Exceptions are made for telecommunication services that must be maintained for security or national defense reasons.

As of September 30, 2010, the Company’s customer portfolio had no subscribers whose receivables were individually higher than 1% of the total accounts receivable from services.

The Company is also subject to credit risk arising from short-term investments, letters of guarantee received as collateral in connection with certain operations and receivables from swap transactions. The Company controls the credit limit granted to all counterparties and diversifies such exposure among top-rated financial institutions.

Derivatives

All the Company’s derivative instruments have the objective of providing a hedge against the risk of variation in exchange rates arising from assets and liabilities in foreign currency, according to the Company’s risk management policy. As such, any changes in risk factors generate an opposite effect on the hedged end. There are no derivative instruments for speculative purposes and liabilities in foreign exchange are hedged.

The Company has internal controls over its derivative instruments, which, according to management, are adequate to control the risks associated with each market strategy. The Company’s results derived from its derivative financial instruments indicate that the risks have been adequately managed.

Notes to the consolidated quarterly information (Continued) Nine months period ended September 30, 2010 (In thousands of reais – R$) (A free translation of the original report issued in Portuguese)

29. Financial instruments (Continued)

The Company and its subsidiaries determine the effectiveness of the hedge instruments entered into to hedge its financial liabilities upon origination and on an ongoing basis (quarterly). As of September 30, 2010, the hedge instruments taken were effective for the debts they are intended to provide coverage. Provided these derivatives contracts qualify as hedge accounting, the debt covered may also be adjusted at fair value as per the rules applicable to fair value hedge.

Fair value of derivative financial instruments

The discounted cash flow method was used to determine the market value of finance liabilities (where applicable) and derivative instruments (foreign currency swap), considering expected settlement of liabilities or realization of assets and liabilities at the market rates prevailing at balance sheet date.

Fair values are calculated by projecting future operating flows, using BM&F Bovespa curves, and discounting to present value through market DI rates for swaps, as informed by BM&F Bovespa.

The market values of exchange rate derivatives was obtained through market currency rates in force at the balance sheet date and projected market rates were obtained from currency coupon curves. The coupon for positions indexed to foreign currencies was determined using the 360-calendar-day straight-line convention; the coupon for positions indexed to CDI was determined using the 252-workday exponential convention.

The consolidated derivative financial instruments shown below are registered with CETIP. All of them are classified as swaps and do not require margin deposits.

a) Swaps of foreign currency x CDI (R$36,983) – swap operations with several maturities until 2014, with the objective of hedging foreign exchange variation for loans and non-financial commitments, net (debt fair value of R$17,644 and non-financial commitments of R$ 19,337).

b) US dollar x Euro forward (R$31,784) – forward operations maturing on January 3, 2011, with the objective of hedging foreign exchange variation for amounts payable in US dollars (book value of R$30,312).

29. Financial instruments (Continued)

c) Swap CDI + 0,35% x CDI – swap operations maturing until September 2010 with the same flow as that of debentures (Note15). The debentures were fully early redeemed on June 7, 2010 and this swap was also early settled.

d) CDI percentage swap x foreign currency – swap operations maturing on January 3, 2011. The short position of this operation (R$43,063), added to the short position of the US dollar X Euro forward (R$34,019) aims at providing hedge against exchange variation risk on amounts receivable in Euro (book value of R$77,415 receivable).

29. Financial instruments (Continued)

For purpose of preparing the quarterly information, the Company adopted hedge accounting only for its foreign currency X CDI swap operations providing financial debt hedge. Under this methodology, both the derivative and the hedged instrument are stated at fair value.

For the period ended September 30, 2010, derivative operations generated a net consolidated loss of R$5,260 (Note 24). At September 30, 2010, currency hedge transactions generated a net consolidated loss of R$5,341. On June 30, 2010 the Company settled its operations involving swap – CDI + spread vs, %CDI, in the principal amount of R$1,500,000, to cover fixed debentures spread, which generated gains of R$81.

At September 30, 2010, the balance of R$258 is recorded as assets and R$28,334 as liabilities, recognizing the position of derivatives as of that date.

Gains and losses for the nine months period ended September 30, 2010, grouped by contracts, were posted to profit and loss accounts (Note 24), as required by CVM Instruction No.475/08.

Sensitivity analysis of the Company’s risk variables

CVM Deliberation 604/09 requires listed companies to disclose, in addition to the provisions of Technical Pronouncement CPC No. 40 - Financial Instruments: Disclosure (equivalent to IFRS 7), a table showing the sensitivity analysis of each type of market risk inherent in financial instruments considered relevant by management and to which the company is exposed at the closing date of each reporting period, including all operations involving derivative financial instruments.

In compliance with the foregoing, all the operations involving derivative financial instruments were evaluated considering a probable scenario and two scenarios that may adversely impact the Company.

The assumption taken into consideration under the probable scenario was to keep what has been signaled by the market through BM&FBovespa market curves (currencies and interest rates). Accordingly, the probable scenario does not provide for any impact on the fair value of the derivative financial instruments mentioned above. For scenarios II and III, risk variables contemplated 25% and 50% deterioration, respectively, pursuant to the applicable CVM instruction.

Notes to the consolidated quarterly information (Continued) Nine months period ended September 30, 2010 (In thousands of reais – R$) (A free translation of the original report issued in Portuguese)

29. Financial instruments (Continued)

Considering that the Company has derivative instruments only to cover its assets and liabilities in foreign currency, the changes in scenarios offset by changes in the related hedged items, thus indicating that the effects are practically null. For these operations, the Company reported the value of the hedged item and of the derivative financial instrument on separate rows in the sensitivity analysis table in order to provide information on the Company’s net exposure for each of the three mentioned scenarios, as shown below:

45

To determine the net exposure of the sensibility analysis, all derivatives were considered at market value and only (hedged elements) classified under hedge accounting method were also considered at fair value.

The fair values shown in the table above are based on the status of the portfolio as of September 30, 2010, not reflecting an estimated realization in view of the market dynamics, always monitored by the Company. The use of different assumptions may significantly impact estimates.

Management comments on consolidated performance (In millions of reais – R$) September 30, 2010

(A free translation of the original report issued in Portuguese)

1. Net operating revenue accumulated through September 2010 amounted to R$11,764,8 million, which, when compared to R$11,810,5 million recorded in the same prior-year period, represented a decrease of R$45,7 million, or 0.4%. The major reductions occurred in local fixed telephone revenues, explained by a drop of VC1 traffic and fixed-to-fixed traffic in the period. Such effects were offset against the increase in revenues from network use, due to higher incoming traffic originating from fixed and mobile network, broadband and data services in the corporate segment.

2. Operating expenses decreased by R$24,7 or 0.3%. The major variations are explained by: a) personnel expenses arising from headcount increase in workforce and increase in provisions for bonuses; b) third-party services, mainly with advertising, client serving and selling expenses. Such an increase was offset by a decrease in expenses with depreciation, as a result of the revaluation of the useful life of the assets (switching centers, equipment and cables), and allowance for doubtful accounts expenses, explained by the improvement in customer base profile as a result of the Company´s concerted efforts through its commercial and collecting policy and practices.

3. Financial expenses: presented a decrease by R$48,8 million, or 35.64%, as a result of a reduction in net indebtedness.

4. Investments

The Company confirms the long-term commitment of the Telefonica Group in Brazil regarding both maintenance and socialization of traditional business and growth of new services, with better and more comprehensive customer services.

Up to September 30, 2010, the Company invested the consolidated amount of R$1,365,6 million.
