(b) Each Strategic Plan
  shall be developed by Embratel with MCIs assistance and presented to the
  Board of Directors of EMBRATEL (the Board) for its approval.


|3.03 Organizational
        Structure and Designation of Personnel.
|-------------------------------------------------------------------

(a) MCI shall advise EMBRATEL on any restructuring of, or modifications to, the organizational structure of EMBRATEL (the Organizational Structure) which MCI may deem advisable and propose to EMBRATEL, from time to time, the personnel to occupy positions within EMBRATEL and its Affiliates. MCI shall endeavor that any such proposal comply with all pertinent labor laws, regulations, and agreements (including the Share Purchase Agreement). Any action shall be taken only at the direction of Embratel management and shall strictly comply with all pertinent labor laws, regulations, and agreements (including the Share Purchase Agreement). The designation and/or ratification of senior management and changes in the Organizational Structure shall be subject, where appropriate, to the approval of the Board in accordance with EMBRATELs By-laws.


(b) The officers and senior management employees proposed by MCI shall, to the knowledge of MCI, have the professional and technical qualifications to perform the functions that in each case are assigned to them. MCI shall assess such qualifications on the basis of objective evaluation methods. Such persons may come from MCI and its Affiliates, from EMBRATEL through internal promotion or from unaffiliated third parties.


|ARTICLE IV
|----------
|          
|PAYMENTS  

4.01 Management Fee.
  EMBRATEL shall pay MCI as compensation for the Management Services a management
  fee (the Fee) which shall be the amount resulting from the application
  of the percentage stipulated below on EMBRATELs Annual Revenue derived
  from the Services.

The percentage to be applied shall be 1% per annum through December 31, 2000; 0.5% per annum from January 1, 2001, through December 31, 2002; and 0.2% per annum as of January 1, 2003.

Embratel agrees to provide MCI with appropriate office space, computer equipment and software, telephones, copiers, and local transportation, at its own expense.

|4.02 Payment Terms.
|-------------------

(a) The Fee shall be payable in advance in quarterly installments
    payable no later than the first day of the corresponding calendar quarter
    and shall be calculated by applying the formula set forth in Section 4.01
    of this Agreement to the applicable portion of EMBRATELs
    revenue for that quarter as set forth in the current business plan approved
    by the Board (Advance Fee). In order to reconcile discrepancies
    between the Advance Fee, based on forecasted revenue, and actual revenue earned
    by EMBRATEL during the same quarter, at the end of each
    calendar quarter EMBRATEL will calculate all revenue of said quarter arising
    out of the Services, including revenues due but not yet paid (EMBRATELs
    Quarterly Revenue). The percentages set forth in Section 4.01 of this
    Agreement will then be calculated over EMBRATELs Quarterly Revenue.
    The Fee payment at the end of each quarter (in addition to the Advance Fee,
    if applicable) shall be calculated by multiplying the final full quarterly
    portion of Annual Revenue, based upon the applicable financial statements
    of EMBRATEL, by the applicable percentage referred to in Section 4.01, and
    subtracting therefrom the Advance Fee payment made with respect to such quarter
    (Adjusted Fee). Any excess Advance Fee payments shall be deducted
    from subsequent installments due, or at EMBRATELs option, shall be promptly
    refunded by MCI. As the Services are invoiced by EMBRATEL in Brazilian current
    currency, but the Fees are to be paid in U.S. dollars, the calculation of
    both the Advance Fee and the Adjusted Fee shall use the average U.S. dollar
    sales rate, employed by major commercial banks operating with the floating
    exchange rate (commercial rate) in the City of Rio de Janeiro, Rio de Janeiro,
    Brazil, for the first day of the calendar quarter for which such Advance Fee
    or Adjusted Fee is calculated. Once said conversion to U.S. dollars has been
    made, the corresponding Fee shall henceforth for all legal purposes be referred
    to in U.S. dollars. EMBRATEL shall send to MCI every quarter, within 30 (thirty)
    days following the end of said period, a written report of all invoicing and
    the calculation of the Fees during said period. In addition, the Fee payment
    at the end of each Fiscal Year shall be calculated by multiplying the final
    full year Annual Revenue based upon the audited financial statements of EMBRATEL
    by the applicable percentage referred to in Section 4.01, and subtracting
    therefrom all prior Fee installment payments made with respect to such Fiscal
    Year. Any excess payments shall be deducted from subsequent installments due,
    or at EMBRATELs option, shall be promptly refunded by MCI.


5

---



Any late payments made by EMBRATEL will be subject to a fine
  of 5% (five percent) and a late payment interest rate of 1% (one percent), calculated
  pro rata monthly, over the amounts due in US dollars, provided that the percentage
  limitations set forth in Section 4.01 are not exceeded.

9.05 Entire Agreement. This Agreement contains the
  entire agreement, and supersedes all prior agreements and understandings and
  arrangements, oral or written, between the Parties with respect to the subject
  matter hereof.

9.06 Amendment. This Agreement may not be modified,
  amended or changed in any respect except in writing duly signed by the Party
  against whom enforcement of such modification, amendment or change is sought.

9.07 Successors and Assigns. All of the terms and
  provisions of this Agreement shall be binding upon and shall inure to the benefit
  of the Parties and their respective successors and permitted assigns.

9.08 Assignment. Except as provided in Section 9.09,
  no Party shall assign this Agreement, in whole or in part, without the prior
  written consent of the other Party, and any such assignment contrary to the
  terms hereof shall be null and void and of no force or effect. No permitted
  or purported assignment of all or any portion of this Agreement shall effect
  a release of the transferor of its obligations under this Agreement without
  an express written release from such obligations by the other Party.

9.09 Assignment by MCI. Notwithstanding Section
  9.08, MCI may assign or transfer its rights and obligations under this Agreement
  to any Affiliate of MCI, including entities organized under the laws of Brazil,
  without the consent of EMBRATEL.

9.10 Interpretation. Whenever possible, each provision
  of this Agreement shall be interpreted in such manner as to be effective and
  valid under applicable law, but if any provision of this Agreement shall be
  unenforceable or invalid under applicable law, such provision shall be ineffective
  only to the extent of such unenforceability or invalidity, and the remaining
  provisions of this Agreement shall continue to be binding and in full force
  and effect. In the event of such unenforceability or invalidity the Parties
  shall negotiate in good faith to agree on changes or amendments to this Agreement
  which are required to carry out the intent of this Agreement in light of such
  unenforceability or invalidity.

9.11 Counterparts. This Agreement may be executed
  in counterparts, each of which shall be deemed to be an original, and all such
  counterparts together shall constitute one and the same legal document.

9.12 Language. This Agreement and any amendments
  or other modifications hereof shall be executed in the English language and
  translated into Portuguese for convenience. In the event of a conflict between
  the English language and the Portuguese language versions of this Agreement,
  the English language version shall prevail.

9.13 Headings. The Article and other headings contained
  in this Agreement are for convenience only and shall not be deemed to limit,
  characterize or interpret any provision of this Agreement.

9.14 Force Majeure.Any failure by a Party to perform
  obligations and responsibilities under this Agreement (other than payment obligations)
  shall not be considered a breach of this Agreement if and to the extent such
  failure to perform is caused by one or more occurrences beyond the reasonable
  control of the Party affected, including without limitation acts of God, earthquakes,
  volcanic eruptions, hurricanes or other natural disasters, embargoes, acts of
  government in exercising its sovereign capacity, governmental restrictions,
  strikes, labor unrest, riots, wars or other military action, civil disorders,
  rebellion, acts of terrorism, sabotage, or political or economic crisis or instability
  (each a Force Majeure Event). The Party suffering the Force Majeure
  Event shall promptly notify the other Party in writing of the details of such
  Force Majeure Event and thereupon the obligations of the Party giving such notice
  shall be suspended during, but not longer than, the continuance of the Force
  Majeure Event. The affected Party shall use all reasonable diligence to remove
  the Force Majeure Event as quickly as possible, provided that this requirement
  shall not require the settlement of strikes, lockouts or other labor difficulty
  by the Party involved, contrary to its wishes, and how all such difficulties
  shall be handled shall be entirely within the discretion of the Party involved.
