                  expiration of this Addendum, before the expiration of the

                  shall keep supplying the Services rendered to the Contracting
                  Party, pursuant to the terms of this Addendum and of its
                  Exhibits, pursuant to the same conditions agreed upon, for the
                  minimum term of ninety (90) days, at the Contracting Party's
                  exclusive discretion, as of such termination date, with no
                  prejudice to payment obligations due with respect to such

         8.1.     None of the Parties shall be considered in default of its
                  duties set forth in the Agreement or in this Addendum if and
                  provided that its performance is directly or indirectly
                  prevented or delayed by Acts of God and/or force majeure
                  events, as set forth in the Brazilian Civil Code (hereinafter
                  any of such events shall be called "Force Majeure Event").
                  Notwithstanding what has been detailed herein, if Contracted
                  Party's suppliers fails to comply with its duties taken over
                  in the letter's agreement with the Contracted Party, this
                  shall not constitute a Force Majeure Event for the Contracted
                  Party, unless such fault, on the part of the supplier, is
                  caused by a Force Majeure Event.

         8.2.     Concerning any Force Majeure Event, the damaged Party shall
                  not be compelled to comply with its duties, then affected
                  during the period through which such circumstances remain, and
                  such Party shall exert its best efforts to resume its
                  performance, as soon as possible. Any Party, whose performance
                  is prevented or delayed by the Force Majeure Event shall
                  forthwith notify the other Party through telephone contact (to
                  be confirmed in writing in up to two (02) weekdays as of the
                  outset of such delay) and describe in detail the Force Majeure
                  Event. In so far as one Party can reasonably foresee that it
                  will be affected by a Force Majeure Event, such Party shall
                  immediately notify the other Party of such foreseen delay and
                  describe, in as much detail as possible, the force Majeure
                  Event.

         8.3.     If a Force Majeure Event prevents or delays the Contracted
                  Party's performance for more than thirty (30) consecutive
                  days, then, the Contracting Party can hire any third parties
                  for the services set forth in this Addendum, without incurring
                  in any fines or penalties, being ascertained that, subsequent
                  to that discontinuance of the service providing by the
                  Contracted Party, the Contracting Party commits to restore the
                  provisions of this Addendum and its Exhibits in up to thirty
                  (30) consecutive days.

9. NINTH CLAUSE - MISCELLANEOUS.

         9.2.     The Exhibits mentioned hereinbelow, initialed by the Parties,
                  integrate this Addendum for legal purposes.

         9.3.     This Addendum constitutes the full agreement between the
                  Parties, related to the subject matter in question, replacing
                  each and any document produced about the same subject. Each
                  and any modification, alteration or addendum to the present
                  Addendum shall only be valid if performed through a written
                  document, signed by all the Parties.

                  9.3.1.   Activation or deactivation of the TC DIAL IP Service
                           by the Contracted Party, stemming from the
                           Contracting Party's written request shall be
                           considered an automatic addendum to the present
                           Addendum, particularly its Exhibits 1.4 and 1.5.

         9.4.     In case of any divergence between the present Addendum and any
                  of its Exhibits, the provisions of this Addendum shall always
                  fully prevail.

         9.5.     Each Party states and guarantees that (i) it has the necessary
                  power and authority to hire and comply with the duties and
                  transactions described in the Agreement and in the present
                  Addendum and (ii) the execution, the delivery and the
                  compliance with the Agreement and the present Addendum and the
                  accomplishment of the transactions described by the Agreement
                  and the present Addendum have been duly authorized in
                  accordance with the necessary procedures of the respective
                  Party.

         9.6.     In case any of the terms of this Agreement or of this Addendum
                  eventually conflict with the law under which the Agreement and
                  this Addendum are constituted or if any of the terms herein
                  set forth is considered invalid by a court with jurisdiction
                  over both the Parties, the rest of the Agreement or of this
                  Addendum shall remain in full validity. In case the invalidity
                  of the said terms prevents the compliance of the fundamental
                  purpose of this Agreement, the Contracted Party and the
                  Contracting Party shall forthwith start negotiations in good
                  faith to refund the affected Party of such a fact of the value
                  (either cash or in services) equivalent to the amount that
                  such Party would have received in case such terms had not been
                  considered invalid.

         9.7.     In the assumption that the Contracted Party is forbidden to
                  provide the services hired by the present instrument, by order
                  of the National Agency of Telecommunications (ANATEL),
                  provided that such a prohibition had not stemmed from acts of
                  the Contracted Party's responsibility, including, but not
                  limiting, failing to comply with the present concession
                  agreement or by virtue of any modification in the applicable
                  legislation in force, the present instrument shall be
                  forthwith terminated through the Contracted Party's written
                  notice to the Contracting Party, informing that it shall be
                  immediately terminated. The Agreement's termination for such a
                  reason, even if on the grounds of acts of the Contracted
                  Party's responsibility shall not provide any of the parties
                  with any right to indemnification, reparation and/or
                  compensation and the Contracted Party shall have to exert its
                  best efforts to assure the continuity of the hired service.

         9.8.     Except for the cases where the previous liberation to the
                  other Party is impossible by law, none of the Parties shall
                  issue any notices to the press, advertisements and marketing
                  material, advertising or other promotional materials related
                  to the Agreement or to the present Addendum or that make
                  reference to the other Party or to its commercial names,
                  trademarks or service marks without the previous written
                  authorization of the other Party, which shall not be denied or
                  put off without feasible reasons.

                  9.8.1.   Notwithstanding the aforedetailed, (i) any of the
                           Parties can issue press releases and other notices,
                           as requested by the United States Securities and
                           Exchange Commission, without the other Party's
                           authorization, and (ii) the Contracting Party can
                           issue press releases solely mentioning the existence
                           of this Addendum, without the Contracted Party's
                           authorization.

         9.9.     All the notices, requisitions, demands and determinations
                  under this Agreement (except for communications of operational
                  routine and the ones hereby specified) shall be in writing and
                  shall be considered as having been properly delivered (i) when

provided that one Party gives the other previous notice of this new address and
the date when it will become effective.

         9.10.    Nothing herein contained shall be interpreted as creation of
                  any representation, partnership or any other type of company
                  formation between the Parties.

         9.11.    The Parties make themselves responsible for the payment of

                  Services to be provided, responsibility which falls fully to
                  the respective Party. Besides, each Party assumes full labor
                  responsibility for their personnel, including social, social
                  security, death, administrative, disciplinary, fiscal and/or

                  with the adverse Party.

                  9.11.1.  In case any complaints or judicial claims are filed
                           against one of the Parties by an employee, director,

                           defendant in such a complaint or claim. In case this
                           substitution is unfeasible, the adverse Party agrees
                           to refund the other Party for any expenditures
                           (including attorneys' fees for loss of suit)
                           incurred by such Party in the filed complaint or
                           claim.

         9.12.    The Parties forthwith agree that any duties that remain in
                  force after the termination, the cancellation or the
                  expiration of this Agreement, of this Addendum and its
                  Exhibits shall survive and remain in force, as expressly set

         9.13.    Both the Parties shall act in compliance with all the laws and
                  regulations which are relevant to its respective performance,
                  pursuant to this Agreement and/or this Addendum. The
                  Contracted Party shall not collect, sue, file or reveal any

1.1.     As of the Addendum's execution date, the Services shall fully comply
         with the ITU - International Telecommunication Union - standards for
         V.90 protocols, as revised by ITU on September 1998.The Contracted
         Party agrees to offer the V.90 protocol immediately after they are made
         available in its network. Additionally, the Services shall comply with
         all the successions, developments and betterments to such protocols
         within the time period to be agreed upon between both the Parties, as
         of their adoption by ITU.

1.2.     The Services shall be in accordance with the Contracting Party's access
         methods, access technology, central architecture and other access
         methods that may eventually become available to the Contracting Party
         or that may be implemented pursuant to the terms of clause 2.4
         hereinbelow. The access methods shall include:

1.2.1.   L2TP- level 2 of tunneling based on 2661 RFC, using a common field
         frequency to route the traffic to the Contracting Party. The
         Contracting Party shall appoint the routable IP address. 1.2.2.
         Point-to-point standard protocol - PPP- based on 1661 RFC. The
         Contracted Party shall furnish a sole routable IP address for each
         session as of a group of IP addresses allotted to the Contracting
         Party. An ordinary certification is used for each session.

1.2.3.   P3 protocol of the Contracting Party's ownership - a Contracting
         Party's protocol guided by characters using a simple or basic telnet
         model -TCP. The remote access provider makes use of a user's ordinary
         identification and password for each session.

1.2.4.   TCP/IP;

1.2.5.   UDP.

2. PROVIDERS OF REMOTE ACCESS.

2.1.     The providers of remote access shall stem from suppliers of good
         standing in the market (first line) and shall be preferably compatible
         for digital connections. Such equipment shall comply with the
         specifications of certification and ticketing implemented by the
         Contracting Party and shall block national return calls, coming from
         the Contracted Party's network.

2.2.     In no circumstances shall the Contracted Party simultaneously use
         different access technologies for the same telephone number.

2.3.     The Parties mutually agree about the technology used by the Contracted
         Party for the Access Ports at the outset of the Services rendering. The
         Contracted Party shall give to the Contracting Party written previous
         notice with at least sixty (60) days in advance about any changes
         whatsoever related to the suppliers of Access Port's equipment, which
         are used to provide the services set forth in this Exhibit and in its
         Addendum, prior to the implementation of such changes. The Contracted
         Party will not be allowed to implement any of the aforementioned
         changes without the Contracting Party's previous written consent. By
         virtue of the afore-established, it is forthwith agreed that the
         Contracted Party shall maintain the right not to expand more ports to
         the Contracting Party, as set forth in the Addendum. We cannot agree
         with this because of exclusivity.

2.4.     The Contracted Party agrees to make use of all commercially reasonable
         efforts to implement, with no additional costs to the Contracting
         Party, any new technology (including any hardware or software upgrades)
         as soon as possible, if so requested by the Contracting Party. In case
         the Contracted Party has implemented a new technology just as an
         outcome of the Contracting Party's request and such technology has not
         been introduced by the Contracted Party as a result of the Contracted
         Party's obligation, in accordance with the aforementioned terms, then,
         if there are any sole costs associated with the implementation of such
         new technology, such costs shall be shared among the beneficiaries. In
         case of its being the sole beneficiary, then the Contracting Party
         shall bear all the costs. Refunding of such costs shall not imply
         reduction or exemption of the monthly costs related to services
         providing, which make use of such new technology.

                                      A-4
<PAGE>

3. ROUTERS AND SWITCHES

Such equipment shall be furnished to the first line suppliers, taking into
consideration the specific configuration needs of each locality. They must be
flexible so as to accept, including but not limiting to, QoS,CoS and filters.

4. INTERCONNECTION OF THE CONTRACTED PARTY'S NETWORK AND THE CONTRACTING PARTY'S
   NETWORK.

4.1.     The Contracted Party commits to provide routing to a point of physical
         interconnection with the Contracting Party's facilities, in a meeting
         point determined by the Contracting Party where the dialed access
         traffic will be delivered by the Contracted Party to the Contracting
         Party (each of such points being a "Meeting Point").

5. TRAFFIC CACHING DEVICES

The Contracting Party and the Contracted Party will be able to examine caching
solutions that aim at bettering the reply times to the Contracting Party's
content, at diminishing the traffic in the internal links of the Contracted
Party's Network, provided that the correct accessibility to the Contracting
Party's content is assured and the information about the traffic of the
Contracting Party's users and subscribers and of the visiting users are kept.

6. MONITORING OF THE CONTRACTED PARTY'S NETWORK SERVICES

The Contracted Party shall make available to the Contracting Party such devices
that will allow the monitoring of the occupation (in absolute and percentage
terms) of the ports' and circuits' data in real and historical time.

7. ARCHITECTURE INDEPENDENCE

In case the Contracted Party establishes that the offer of another operator
features a better value, or other factors that may favor the offer of the other
operator, the Contracted Party may make use of a different operator from its
current one for its network or for any part of it, provided that, nevertheless,
such uses do not adversely affect the services supplied pursuant to this
Addendum. The Contracted Party shall provide the Services in such a way that is
compatible with the Contracting Party's targets of attaining architecture
independence. Along these lines, the Contracted Party shall:

(a)      manage all its providers of network service so as to minimize the
         possibility that a single failure may impact the Contracting Party's
         service and

(b)      guarantee that each of the Contracted Party's service provider
         minimizes the possibility that a single failure may impact the
         Contracting Party's service. The Contracted Party shall request the
         Contracting Party's approval before making use of a new operator
         besides its current operator in accordance with what is allowed by this
         Article.

         With limiting to the Contracted Party duties describe above, the
         Contracted Party will project and execute the Network used to provide
         the services to the Contracting Party as set forth in the present
         Addendum in a manner that there will be no unique point of failure in
         such Network, which could result in an important adverse effect in the
         cities that are capitals of States located in Region I of the GPG.

EXHIBIT 2.4 (II) QUALITY CRITERIA

1.BASIC CRITERIA

The regularity and the non-interruption of the Contracting Party's services and
of the subscribers' connection to the Internet and to the Contracting Party's
content is of major importance. Thus, the quality criteria shall include:

1.1.     real time monitoring of the occupation of the ports and access links of
         the Contracting Party's Network, separated by locality, offering to the
         Contracted Party the remote online monitoring of the communication
         ports, via a page made available in the Internet and protected by a
         password;

1.2.     access ports associated to the Contracted Party's number of lines,
         which are needed to guarantee the full availability of the operation
         attendance at MMT (Major Movement Time), in each performance place, as
         requested by the Contracting Party, with thirty (30) days in advance,
         for increases of up to

                                      A-5
<PAGE>

         three hundred and fifty (350) new ports at each thirty(30) days. Above
         such amount, the Contracted Party agrees to exert its best efforts for
         the term of enlargement not to overcome ninety (90) days.

1.3.     managerial reports and logs (both offline) of the sessions performed in
         the access network, containing all the samples of the variables used to
         prepare the online monitoring graphs as well as the real and the
         percentage occupation (number of ports and kbps, respectively) per
         attended place;

1.4.     provide daily reports, under request, of the percentage of non-effected
         calls, including their respective causes, whenever requested by the
         Contracting Party, provided that the need is actually attested.

2. GUARANTEES AND SLA

The Contracted Party shall guarantee the minimum allocation of 10 (ten) kbps per
access port in each locality, and it must analyze, through mutual concord with
the Contracting Party, the future need, according to the demand duly formalized
by the Contracted Party.

The average time for failure repair shall not exceed three (03) hours, being the
period between the outset and the actual solution of such failure taken into
consideration, independently of the time of the occurrence opening.

2.1.     The performance indexes to be used as a reference for the Guarantee of
         Service Level (SLA) of the Contracted Party's Access Network are:

EXHIBIT 2.10. - TECHNICAL DESCRIPTION OF SOLUTION

The TC Dial IP is a solution for the supply of dialed access to the Internet
with high quality and reliability which makes available the most modern
infra-structure and the advanced management to companies that wish to act as
Internet service providers, outsourcing the necessary infra-structure. The
solution is valid for the Contracting Party in the more than 140 presence points
of the Contracted Party's Backbone I P in Region I.

Dialed access to the Internet is the access performed through the Commuted Fixed
Telephony Service (CFTS) by means of the Remote Access Service (RAS) which
performs the interface between the Telephony Network and the IP/Internet
Network. It constitutes a predominant form of access to the great public, due to
CFTS's extensive capillarity and penetration.

When contracting the TC Dial IP, the Contracting Party becomes able to offer
dialed access to the Internet to its users, clients, partners and suppliers. The
Contracting Party makes available telephone numbers attended to by an
infrastructure capable of receiving modem calls and of connecting the computers
which have originated the calls to the Internet.

The TC Dial IP will allow the Contracting Party to keep the focus on its clients
enjoying its high capillarity and the quality in the service rendered,
outsourcing part of the infra-structure of access to the Internet and being its
management under the Contracted Party's responsibility, with the possibility of
Remote Monitoring, by the Contracted Party, of the Access Interfaces available
in the Contracted Party's IP Network.

1. TOPOLOGY OF THE SOLUTION

The connection model, exclusive for the delivery of the TC Dial IP service to
the Contracting Party, is detailed in the figure hereinbelow:

The TC Dial IP has its quality acknowledged by Cisco, having received the seal
"Cisco Powered Network - CPN" to attest it. The RAS used are all of them Cisco's
last generation equipment, assuring the higher quality of connection and extreme
reliability.

         3.3. Rejection. If a Port fails to comply with any of the Acceptance

         corrected and such Ports meet the Acceptance Criteria.

         trials for curing the Non-Conformities, the Contracted Party has not
         delivered the respective Port, according to the applicable Acceptance

         with no cost or liability for the Contracting Party, the total or the
         part which has not been met of the Accepted Request as of a specific
         date, through a written cancellation notice issued by the Contracting

         towards the Contracted Party related to any cancelled part of the
         request.

services for AOL Switched Access National Network, as provided in Section 1 of
the Agreement and according to Exhibits "D" and "C" thereof.

II.- On October 31, 2001, the Parties entered into (i) a letter agreement to

<PAGE>

                                     CLAUSES

FIRST.-  PORTS
1. PORT CANCELLATION; PENALTIES.- The Parties hereby agree to the cancellation
of the [**] Ports identified in Annex 1 attached hereto (the "Cancelled Ports")
as of the effective dates specified in Annex 1.

AOL and AVANTEL agree that, notwithstanding anything to the contrary in the Main
Agreement, the penalties for the early cancellation of the Cancelled Ports shall
be the ones indicated in the following table:

--------------------------------------------------------------------------------
                 CONCEPT                             PENALTY
--------------------------------------------------------------------------------
               [**] Ports                            USD$[**]
--------------------------------------------------------------------------------
              STM-1 Dallas                           USD$[**]
--------------------------------------------------------------------------------
                  TOTAL                              USD$[**]
--------------------------------------------------------------------------------

AVANTEL will invoice AOL the above-mentioned penalties on or before June 26,
2003 and AOL will pay such penalties on or before December 31, 2003. AOL shall
be responsible for any Value Added Tax ("VAT") which is owed as a result of the
payment of such penalties.

AVANTEL recognizes and acknowledges that the amounts of these penalties were
calculated by AVANTEL itself and accepted by AOL.

AVANTEL will receive the payments from AOL as indicated here: $[**] United
States Dollars, plus VAT, by wire transfer to the JP Morgan Chase bank, Account
No. [**] ABA [**] in favor of AVANTEL S.A.

AVANTEL acknowledges and agrees that the amounts payable to it under this
Section 1 shall be the only amounts AVANTEL will be entitled to receive from AOL
in connection with the cancellation of the Cancelled Ports, and that no other
amounts whatsoever shall be owed as a result of such cancellation.

2. Remaining Ports.- Avantel agrees that, except as otherwise provided herein,
it shall continue to provide the Ports specified on Annex 2 (the "Remaining
Ports") in accordance with the terms of the Main Agreement. The price of the
Remaining Ports shall be MXP$[**] plus applicable taxes per month per Port from
July 1, 2003 through September 30, 2005.

3. Volume Discount.- AVANTEL shall commit to the volume discounts set forth
below for all Ports installed pursuant to the terms of the Main Agreement or any
other arrangement between the Parties. Once the aggregate number of Ports meets
one of the volume thresholds in the table below, the relevant price
corresponding to that threshold shall apply to all Ports, not just to the excess
number of Ports above the threshold.

4. Modification of Clause (iii) of the December 13 Letter Agreement. The Parties
agree that the [**]% discount against invoiced amounts in calendar years 2003
and 2004 to which AOL is entitled under clause (iii) of the December 13 Letter
Agreement shall be provided to AOL based on an alternative scheme. In lieu of
calculating the [**]% discount in advance each year based on forecasted invoice
amounts, the [**]% discount shall be calculated each month based on the gross
amount of each invoice (i.e. excluding any other discounts to which AOL may be
entitled under the December 13 Letter Agreement or any other agreement). As a
result of the discount being calculated monthly based on actual invoiced
amounts, the year-end review/adjustments provided for under clauses (iii)(c) and
(iii)(d) of the December 13 Letter Agreement will no longer be necessary. The

                                       2
<PAGE>

Parties agree that a review will be made within 30 days of the Effective Date
(the "Adjustment Date") to determine the amount of any discrepancy between
discounts provided under clause (iii)(b) of the December 13 Letter Agreement
from January 1, 2003 through the Adjustment Date and the actual [**]% discount
to which AOL was entitled based on the gross invoices during such period. To the
extent such review shows any surplus or deficiency in the amount of discounts
provided, an adjustment to remedy such discrepancy shall be set forth in the
first invoice delivered by AVANTEL following such date.

5. Modem access number changes:

     a.   The [**] Remaining Ports in the 1943-2265 Mexico City access number
          will be migrated to the following access numbers:

          o    [**] modems to the 5448-8400 access number

          o    [**] modems to the 9160-0000 access number

     b.   The [**] Remaining Ports in the 8122-9999 Monterrey number will be
          migrated to the following number:

          o    [**] modems to a local AVANTEL access number to be defined by
               AVANTEL

For the Ports in the two cities mentioned in clauses a. and b. above, it will be
considered that the installation dates of the Ports in the new DIDs is the
original date of delivery, in other words, July 4, 2000 for Mexico City and
December 7, 2000 for Monterrey.

AOL grants Avantel permission to send all traffic through the Internet instead
of using an International Private Line. Avantel hereby agrees to send the
aforementioned traffic through redundant Internet circuits of higher than STM-4
capacity. Furthermore, Avantel agrees that these circuits will not be used above
[**]% during peak hours.

SECOND.- RELEASE.

As consequence of having received at its entire satisfaction and conformity the
payment of the amounts referred to in the first article, upon execution of this
Agreement, AVANTEL on behalf of itself and all of its officers, directors,
stockholders, employees, agents, successors, assigns, parent and subsidiary
corporations, and related entities and affiliates (collectively, the "AVANTEL
Releasing Parties"), hereby releases and irrevocably discharges AOL and all of
AOL's officers, directors, stockholders, employees, agents, successors, assigns,
parent and subsidiary corporations, and related entities and affiliates
(collectively, the "AOL Released Parties") from any and all complaints, claims,
causes of action, suits, costs, losses, liabilities, damages, and demands of any
kind, whether known or unknown (collectively, "Claims"), which any of the
AVANTEL Releasing Parties has alleged or could have alleged against any of the
AOL Released Parties as of the Effective Date, which relate to, or arise from
the subject matter of the Main Agreement.

THIRD.- GENERAL

Parties hereto acknowledge that except as set forth herein, all the other terms
and conditions of the Main Agreement, shall remain in full force and effect,
including, without limitation, with respect to the Remaining Ports.

FOURTH.- CONFIDENTIALITY

This Agreement, including the amounts paid by AOL to AVANTEL hereunder, shall be
considered as confidential by the Parties, and shall be governed as stated in
Section 9 of the Main Agreement. Notwithstanding the foregoing, either Party may
disclose this Agreement, including the terms hereof, without the consent of the
other Party, to the extent such disclosure is required by law, rule, regulation
or government or court order. In such event, the disclosing Party shall provide
at least three (3) days prior written notice of such proposed disclosure to the
other Party. Further, in the event such disclosure is required of either Party
under the laws, rules or regulations of any applicable governing body, such
Party shall (i) consider in good faith any request made by the other Party to
redact certain portions of this Agreement to the extent permitted under
applicable laws, rules and regulations and (ii) submit a request to such

                                       3
<PAGE>

governing body that such portions and other provisions of this Agreement receive
confidential treatment or otherwise be held in the strictest confidence to the
fullest extent permitted under the laws, rules or regulations of the applicable
governing body. For the avoidance of doubt, the final determination at to what
portions of the Agreement shall be redacted, if any, shall be made by the
disclosing Party in its sole discretion.

Spanish version shall always prevail in the event of any disputes concerning
this Agreement.

SIXTH.- JURISDICTION, INTERPRETATION AND ENFORCEABILITY.

For the interpretation, fulfillment and enforceability of this document, PARTIES
submit themselves to the applicable laws and competent federal courts in Mexico
City, Federal District, expressly waving any other forum to which they could be
entitled resulting from their present or future domiciles.

Considering this Agreement contains no article contrary to law, and contains no
willful act, bad intention or any other reason that may invalidate it, the
Parties sign two copies on July 1st, 2003, and such date shall be the day on
which this Agreement becomes effective ("Effective Date").
