“First Supplemental Indenture”), among EMPRESA BRASILEIRA DE TELECOMUNICAÇÕES S.A., a company organized under the laws of the Federative Republic of Brazil (herein called the “Company”), having
its principal office at Avenida Presidente Vargas, 1,012-10o andar 20071-910, Rio de Janeiro, RJ, Brazil, EMBRATEL PARTICIPAÇÕES S.A., a company organized under the laws of the Federative Republic of Brazil (herein called

 W I T N E S S E T H : 
  
 Whereas, the Original Indenture provides for the issuance from time to time
thereunder, in series, of Securities of the Company carrying the Guaranty of the Guarantor, and Section 3.1 of the Original Indenture provides for the establishment of the form or terms of Securities issued thereunder through one or more
supplemental indentures; 
  
 Whereas, by means of the First Supplemental
Indenture, the Company and the Guarantor created two series of Securities issued under the Original Indenture, as supplemented by the First Supplemental Indenture, known as the Company’s 11.0% Series A Guaranteed Notes due 2008 (the
“Series A Notes”) and the Company’s 11.0% Series B Guaranteed Notes due 2008 (the “Series B Notes,” and, together with the Series A Notes, the “Notes”) and issued $200,000,000 aggregate
principal amount of Notes; 
  
 Whereas, the First Supplemental Indenture
provides for the issuance from time to time by the Company of additional notes, carrying the Guaranty of the Guarantor, on the terms and conditions identical to those of the Notes, which additional notes shall increase the aggregate principal amount
of, and shall be consolidated and form a single series with, the Notes; 
  
 Whereas, the Company and the Guarantor desire by this Supplement to issue Securities under the Original Indenture and the First Supplemental Indenture, to be consolidated and form a single series with the Notes, limited in aggregate
principal amount as specified in this Supplement, and the terms and provisions of which are to be as specified in the First Supplemental Indenture as supplemented by this Supplement; 
  
 Whereas, all things necessary to make this Supplement a valid and binding legal obligation of the Company and the Guarantor according
to its terms have been done.

	2.	General Terms and Conditions of the Notes 

  

	 	2.1.	Designation and Principal Amount 

  
 The aggregate principal amount, the 11.0% Series A Guaranteed Notes due 2008 and the 11.0% Series B Guaranteed Notes due 2008, are hereby increased to
$275,000,000 (which amount does not include Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of such series pursuant to Sections 3.4, 3.5, 8.6 or 10.3 of the Original Indenture).
For purposes of Section 3.1 of the Original Indenture, this Supplement supplements the First Supplemental Indenture to increase the limit on the aggregate principal amount of the Notes and to set forth the matters expressly set forth herein. All the
Notes issued under the First Supplemental Indenture as supplemented by this Supplement (including, for the avoidance of doubt, the Additional Issue) shall form a single series for all purposes under the Original Indenture, including without
limitation for purposes of waivers, amendments, redemptions, offers to purchase and acceleration. 
  

	 	2.2.	Forms Generally 

  
 Upon their original issuance, Notes offered and sold pursuant to the Additional Purchase Agreement to Qualified Institutional Buyers in accordance with
Rule 144A shall be issued in the form of one or more Restricted Global Notes. Such Restricted Global Notes shall be registered in the name of the Depositary, or its nominee, deposited with the Trustee, at its Corporate Trust Office, as custodian for
the Depositary, duly executed by the Company, and by the Guarantor, in the case of the Guaranty endorsed thereon, and authenticated by the Trustee. 
  
 Upon their original issuance, Notes offered and sold pursuant to the Additional Purchase Agreement in reliance on Regulation S shall initially be issued
in the form of one or more Regulation S Global Notes. Such Regulation S Global Notes shall be registered in the name of the Depositary, or its nominee, deposited with the Trustee, at its Corporate Trustee Office, as custodian for the Depositary,
duly executed by the Company, and by the Guarantor, in the case of the Guaranty endorsed thereon, and authenticated by the Trustee. After such time as the Additional Distribution Compliance Period shall have terminated, each such Regulation S Global
Note shall be an “Unrestricted Global Note” for all purposes under the First Supplemental Indenture. 
  
 Section 2.2.1 of the First Supplemental Indenture provides that the first paragraph of the reverse of each Global Note, contains a phrase “initially
limited in aggregate principal amount to $200,000,000.” In the Global Notes delivered pursuant to this Section 2.2, the words “initially limited in aggregate principal amount to $200,000,000” shall be amended to read “initially
limited in aggregate principal amount to $275,000,000.” 
  

	 	2.3.	Transfers and Exchanges 

  

	 	2.3.1	In case of any transfer or exchange the procedures and requirements for which are not addressed in detail in Section 2.3 of the First Supplemental Indenture or


  

 3 








 this Section 2.3, such transfer or exchange will be subject to such procedures and requirements as may
be reasonably prescribed by the Company and the Trustee from time to time and, in the case of a transfer or exchange invoking a Global Note, the Applicable Procedures. 
  

	 	2.3.2	Notwithstanding the foregoing and the provisions of Section 2.3 of the First Supplemental Indenture, during the period of two years after the Closing Date, the Company shall
not, and shall not permit any of its Affiliates that are Subsidiaries, to purchase or agree to purchase or otherwise acquire any Restricted Notes, whether as beneficial owner or otherwise (except as agent on behalf of and for the account of
customers in the ordinary course of business as a securities broker in unsolicited broker’s transactions) unless, immediately upon any such purchase, the Company or any such Affiliate shall submit such Restricted Notes to the Trustee for
cancellation. The Company further agrees to ask its Affiliates that are not Subsidiaries to agree not to purchase or otherwise acquire any Restricted Notes, whether as beneficial owner or otherwise, except as permitted in the preceding sentence.


  

	 	2.4.	Registration Rights 

  
 The Holders of the Notes are entitled to the benefits of a Registration Rights Agreement dated the date hereof among the Company, the Guarantor and the
Initial Purchasers (the “Additional Registration Rights Agreement”). 
  

	3.	Miscellaneous Provisions 

  

	 	3.1.	Separability of Invalid Provisions 

  
 In case any one or more of the provisions contained in this Supplement should be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provisions contained in this Supplement, and to the extent and only to the extent that any such provision is invalid, illegal or unenforceable, this Supplement shall be construed as if such
provision had never been contained herein. 
  

	 	3.2.	Execution in Counterparts 

  
 This First Supplemental Indenture may be simultaneously executed and delivered in any number of counterparts, each of which when so executed and delivered
shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument.
