Report on review of quarterly information

To the Board of Directors and Stockholders

Telefônica Brasil S.A.

Introduction

We have reviewed the accompanying parent company and consolidated interim accounting information of Telefônica Brasil S.A. ("Company"), included in the Quarterly Information Form (ITR) for the quarter ended June 30, 2017, comprising the balance sheet at that date and the statements of income and comprehensive income for the quarter and six-month periods then ended, and changes in equity and cash flows for the six-month period then ended, and a summary of significant accounting policies and other explanatory information.

Management is responsible for the preparation of the parent company interim accounting information in accordance with the accounting standard CPC 21 - "Interim Financial Reporting", of the Brazilian Accounting Pronouncements Committee (CPC), and of the consolidated interim accounting information in accordance with CPC 21 and International Accounting Standard (IAS) 34 - "Interim Financial Reporting" issued by the International Accounting Standards Board (IASB), as well as the presentation of this information in accordance with the standards issued by the Brazilian Securities Commission (CVM), applicable to the preparation of the Quarterly Information (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and International Standards on Reviews of Interim Financial Information (NBC TR 2410 - "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" and ISRE 2410 - "Review of Interim Financial Information Performed by the Independent Auditor of the Entity", respectively). A review of interim information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Brazilian and International Standards on Auditing and consequently did not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the parent company interim information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying parent company interim accounting information included in the Quarterly Information referred to above has not been prepared, in all material respects, in accordance with CPC 21 applicable to the preparation of the Quarterly Information, and presented in accordance with the standards issued by the CVM.

Conclusion on the consolidated interim information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying consolidated interim accounting information included in the Quarterly Information referred to above has not been prepared, in all material respects, in accordance with CPC 21 and IAS 34 applicable to the preparation of the Quarterly Information, and presented in accordance with the standards issued by the CVM.

Other matters

Statement of value added

We have also reviewed the parent company and consolidated statements of value added for the six-month period ended June 30, 2017. These statements are the responsibility of the Company's management and are required to be presented in accordance with standards issued by the CVM applicable to the preparation of Quarterly Information (ITR) and are considered supplementary information under IFRS, which do not require the presentation of the statement of value added. These statements have been submitted to the same review procedures described above and, based on our review, nothing has come to our attention that causes us to believe that they have not been prepared, in all material respects, in a manner consistent with the parent company and consolidated interim accounting information taken as a whole.

Audit and review of prior-year information

The Quarterly Information Form (ITR) mentioned in the first paragraph includes accounting information, presented for comparison purposes, related to the statements of income and comprehensive income for the quarter and six-month periods ended June 30,2016, and the statements of changes in equity, cash flows and value added for the six-month period then ended, obtained from the Quarterly Information Form (ITR) for that quarter, and also to the balance sheet as at December 31, 2016, obtained from the financial statements at December 31, 2016. The review of the Quarterly Information (ITR) for the quarter ended June 30, 2016 and the audit of the financial statements for the year ended December 31, 2016 were conducted by other independent auditors, whose unqualified review and audit reports were dated July 25, 2016 and February 17, 2017, respectively.
