      (A CORPORATION ORGANIZED UNDER THE LAWS OF THE REPUBLIC OF COLOMBIA)
 
                               The Exchange Offer
      and withdrawal rights will expire at 5:00 p.m., New York City time,
            on                , 1996 (as such date may be extended,
                            the "Expiration Date").
                            ------------------------
     Occidente y Caribe Celular S.A., a Colombian corporation (the "Company" or
"Occel"), is hereby offering to exchange an aggregate principal amount at
maturity of up to US$190,745,000 of its 14% Series B Senior Discount Notes due
2004 (the "New Notes") for a like principal amount at maturity of its 14% Senior
Discount Notes due 2004 (the "Old Notes") outstanding on the date hereof upon
the terms and subject to the conditions set forth in this Prospectus and in the
accompanying Letter of Transmittal (which together will constitute the "Exchange
Offer"). The New Notes and Old Notes are collectively hereinafter referred to as
the "Notes".
 
     The terms of the New Notes are identical in all material respects to those
of the Old Notes, except for certain transfer restrictions and registration
rights relating to the Old Notes. The New Notes will be issued pursuant to, and
entitled to the benefits of, the Indenture (as defined) governing the Old Notes.
 
     The Accreted Value (as defined herein) of the New Notes initially will be
equal to the Accreted Value of the Old Notes at the time of exchange. Cash
interest will not accrue on the New Notes prior to March 15, 2001, from which
time cash interest will accrue on the New Notes at a rate of 14% per annum.
Interest on the New Notes is payable semiannually on each March 15 and September
15, commencing September 15, 2001. The Company will redeem 50% of the original
aggregate principal amount at maturity of the New Notes, on March 15, 2003, at
100% of the principal amount thereof. The New Notes will mature on March 15,
2004. The New Notes will be redeemable at the option of the Company, in whole or
in part, at 100% of the principal amount thereof if redeemed prior to September
15, 2000 and, thereafter, at the redemption prices set forth herein, in each
case together with accrued and unpaid interest, if any, to the date of
redemption. In addition, at any time prior to March 15, 1999, the Company may
redeem up to 33% of the original aggregate principal amount at maturity of the
New Notes from the net proceeds of any Public Equity Offering (as defined
herein) at a redemption price equal to 114% of the Accreted Value (as defined
herein) thereof. The New Notes will be redeemable at the option of the Company,
as a whole, but not in part, in the event of certain changes in Colombian tax
law. Upon the occurrence of a Change of Control, each holder of New Notes may
require the Company to purchase all or a portion of such holder's New Notes at a
purchase price in cash equal to 101% of the Accreted Value thereof, together
with accrued and unpaid interest, if any, to the date of purchase. The Company's
ability to redeem the New Notes is subject to certain limitations under
Colombian law. See "Description of the Notes".
 
     The New Notes will be senior unsecured obligations of the Company ranking
pari passu in right of payment with all other existing and future unsubordinated
obligations of the Company (other than obligations preferred by statute or by
operation of law), except as described in the "Description of the
Notes -- Ranking", and senior in right of payment to all existing and future
obligations of the Company expressly subordinated in right of payment to the New
Notes. The New Notes, however, will be effectively subordinated to senior
secured obligations of the Company with respect to the assets of the Company
securing such obligations.
                                                        (Continued on next page)
                            ------------------------
      SEE "RISK FACTORS" BEGINNING ON PAGE 17 HEREIN FOR A DISCUSSION OF CERTAIN
FACTORS THAT HOLDERS OF OLD NOTES SHOULD CONSIDER IN CONNECTION WITH THE
EXCHANGE OFFER.
                            ------------------------
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES
  SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR
  HAS THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION OR ANY STATE
      SECURITIES COMMISSION PASSED UPON THE ACCURACY OF OR ADEQUACY OF
      THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL
        OFFENSE.
 
                            ------------------------
               The date of this Prospectus is             , 1996.
 
     Information contained herein is subject to completion or amendment. A
     registration statement relating to these securities has been filed with the
     Securities and Exchange Commission. These securities may not be sold nor
     may offers to buy be accepted prior to the time the registration statement
     becomes effective. This prospectus shall not constitute an offer to sell or
     the solicitation of an offer to buy nor shall there be any sale of these
     securities in any State in which such offer, solicitation or sale would be
     unlawful prior to registration or qualification under the securities laws
     of any such state.
<PAGE>   5
 
(Continued from previous page)
 
     The Company will not receive any proceeds from the Exchange Offer. The
Company will pay all the expenses incident to the Exchange Offer. Tenders of Old
Notes pursuant to the Exchange Offer may be withdrawn at any time prior to the
Expiration Date (as defined) for the Exchange Offer. In the event the Company
terminates the Exchange Offer and does not accept for exchange any Old Notes
with respect to the Exchange Offer, the Company will promptly return such Old
Notes to the holder thereof. See "The Exchange Offer".
 
     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. The Letter of Transmittal states
that by so acknowledging and by delivering a prospectus, a broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act of 1933, as amended (the "Securities Act"). This Prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of New Notes received in exchange for
Old Notes where such Old Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities. The Company has agreed
that, for a period of 180 days after the Expiration Date, it will make this
Prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution".
 
     Prior to the Exchange Offer, there has been no public market for the Old
Notes. If a market for the New Notes should develop, such New Notes could trade
at a discount from their accreted value. The Company currently does not intend
to list the New Notes on any securities exchange or to seek approval for
quotation through any automated quotation system and no active public market for
the New Notes is currently anticipated.
 
     The Exchange Offer is not conditioned upon any minimal principal amount of
Old Notes being tendered for exchange pursuant to the Exchange Offer.
 
     The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company under the Purchase Agreement dated as of May 31, 1996
between the Company and the initial purchasers of the Old Notes (the "Initial
Purchasers") and the Registration Rights Agreement dated June 7, 1996 (the
"Registration Rights Agreement") between the Company and the Initial Purchasers.
 
     The Old Notes were issued in a transaction (the "Offering") pursuant to
which the Company issued US$190,745,000 principal amount at maturity of the Old
Notes. The Old Notes were sold by the Company to the Initial Purchasers on June
7, 1996 (the "Issue Date") pursuant to the Purchase Agreement. The Initial
Purchasers subsequently resold the Old Units in reliance on Rule 144A and
certain other exemptions under the Securities Act.
<PAGE>   6
 
     THE ISSUANCE OF THE NOTES HAS BEEN APPROVED BY THE COLOMBIAN
SUPERINTENDENCY OF CORPORATIONS (SUPERINTENDENCIA DE SOCIEDADES) (THE
"SUPERINTENDENCY OF CORPORATIONS"). SUCH APPROVAL DOES NOT IMPLY AN APPROVAL OF
THE QUALITY OF THE NOTES OR THE SOLVENCY OF THE COMPANY. THE NOTES MAY NOT BE
OFFERED OR SOLD IN THE REPUBLIC OF COLOMBIA ("COLOMBIA").
                            ------------------------

this Prospectus reside outside of the United States, and all or a substantial
portion of the assets of such persons and the Company are located outside the
United States. As a result, it may not be possible for investors to effect
service of process within the United States upon such persons, including with
respect to matters arising under the Securities Act of 1933, as amended (the
"Securities Act"), or to enforce against the Company or any of them judgments
obtained in United States courts predicated upon the civil liability provisions
of the federal securities laws of the United States. The Company has been
advised by its Colombian legal counsel, Holguin, Neira y Pombo, that there is
doubt as to the enforceability, in original actions in Colombian courts, of
liabilities predicated solely on the United States federal securities laws and
as to the enforceability in Colombian courts, of judgments of United States
courts obtained in actions predicated upon the civil liability provisions of the
United States federal securities laws. The Company has appointed CT Corporation
System, New York, New York, as its agent to receive service of process with
respect to any action brought against it in any federal or state court in the
State of New York arising from the Exchange Offer. The Company has been advised
by its Colombian legal counsel that a claim by a holder of Notes or Warrants in
connection with the Exchange Offer may be brought in such courts. See
"Enforcement of Foreign Judgments in Colombia".

     Data regarding population in Colombia and the Western Region (as defined
herein) are based on projections of 1995 population figures calculated by the
Colombian National Administrative Department of Statistics (Departamento
Administrativo Nacional de Estadistica) ("DANE") on the basis of the 1985
census. The results of the 1993 census are not officially available yet. There
can be no assurance that these projections accurately reflect the current
population in the Western Region.

                                 EXCHANGE RATES
 
     Until 1991, the Colombian Central Bank (Banco de la Republica) (the
"Central Bank") set an official exchange rate (the "Official Rate") applicable
to all foreign exchange transactions, based on its prevailing economic policy.
Since October 1991, exchange rates have been freely set by the market. The
Colombian Superintendency of Banking (Superintendencia Bancaria) (the
"Superintendency of Banking") calculates and publishes daily the Representative
Market Rate (Tasa Representativa del Mercado) (the "Representative Market Rate")
which is the weighted average of the foreign exchange buy and sell rates quoted
on the previous business day by certain commercial banks and financial
institutions in Santafe de Bogota, Cali, Medellin and Barranquilla for the
purchase and sale of foreign currency. The Representative Market Rate serves as
a basis for establishing the rate used in many foreign exchange transactions
conducted on the foreign exchange market and the free market as defined under
Law 9/1991. From October 1991 through January 1995, the Central Bank set the
Official Rate for certain limited purposes. Since February 1995, the Central
Bank has not established an Official Rate. See "Annex B -- Republic of
Colombia -- Monetary System and Monetary Aggregates -- Foreign Exchange Rates
and International Reserves".
 
     The following table sets forth the Peso/Dollar Official Rate (as defined
below) at the end of each period indicated and, for each such period, the high,

     The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, included
elsewhere in this Prospectus. The Company publishes its financial statements in
Colombian pesos and in accordance with Colombian generally accepted accounting
principles. In this Prospectus, unless otherwise indicated, amounts are
expressed in Colombian pesos ("Ps" or "Pesos") and in United States dollars
("US$" or "Dollars"). The term "billion" as used in this Prospectus means one
thousand million (in Dollars and in Pesos). The "Company" or "Occel" means
Occidente y Caribe Celular S.A.
 
     The term "reported subscribers" means subscribers as reported by the
Company to the Colombian Ministry of Communications. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- General". Consistent with the Company's interpretation of the
Ministry's reporting guidelines and with what the Company believes to be the
common interpretation of cellular operators in Colombia, the Company currently
includes in such term subscribers who have been temporarily disconnected and are
under evaluation by the Company for reconnection or permanent deactivation.
"Active subscribers" is the Company's internal measure of customers currently
generating revenue. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- General" and "-- Price Competition and
Related Matters," for a discussion of the differences between reported and
active subscribers. See also the "Glossary of Certain Telecommunications Terms"
attached as Annex A hereto for a definition of certain terms.
 
                                  THE COMPANY
 
GENERAL
 
     Occel is one of only two providers of cellular telecommunications services
in the densely populated western region of Colombia (the "Western Region"). The
Western Region has a population of approximately 12.8 million people (or
approximately 36% of the country's population), and includes the cities of
Medellin and Cali, the second and third largest metropolitan areas in the
country, as well as thirteen other cities with populations in excess of 100,000
each. The Company commenced commercial cellular service in September 1994,
pursuant to a ten-year concession effective as of March 28, 1994, and has
subsequently generated significant growth in total subscribers and revenues. As
of December 31, 1995 and March 31, 1996, the Company had 40,887 and 48,460
reported subscribers, respectively, and realized average monthly revenue per
active subscriber for the quarters ended December 31, 1995 and March 31, 1996 of
US$141.76 and US$143.84, respectively (in actual Pesos translated at the average
Representative Market Rates for the respective quarters). As of June 30, 1996,
the Company had 56,741 reported subscribers.
 
     Since the launch of its service, the Company has sought to rapidly increase
its coverage areas, establish recognition of its "Vozavoz" brand name and
provide a superior quality of service that is equivalent to that provided by
world class operators. As of March 31, 1996, the Company had reached a
penetration level of 0.56% of the population covered by its cellular network,
which included the metropolitan areas of Medellin (with approximately 2.4
million pops), Cali (with approximately 1.8 million pops), Pereira (with
approximately 0.5 million pops), Manizales (with approximately 0.4 million
pops), Armenia (with approximately 0.2 million pops) and other urban areas
(having in the aggregate approximately 0.7 million pops). In addition, the
Company has roaming agreements with other cellular operators which provide its
customers with nationwide coverage throughout Colombia as well as access in
several other countries.
 
     The Company has invested heavily in constructing a state-of-the-art network
which has dual analog and digital capacity and which can support continued
growth in subscribers as well as technologically advanced new services. As of
March 31, 1996, the Company's cellular telecommunications network covered
approximately 67% of the population of the Western Region. The Company had
incurred approximately Ps 57 billion (US$54 million) in capital expenditures
through March 31, 1996 to build its network, and expects to incur approximately
an additional US$51 million to substantially complete its build-out (including
planned upgrades) by 1999.
 
     The Company's headquarters are located at Carrera 55 No. 49-101, Medellin,
Colombia, and its telephone and fax numbers are 574-512-9090 and 574-513-0199,
respectively.

SHAREHOLDERS
 
     The Company was organized in 1992 and its shareholders include Cable and
Wireless plc ("C&W"), Itochu Corporation ("Itochu") and, through holding
companies, the second and fourth largest wireline telephone companies in
Colombia as well as several other major Colombian public sector and private
sector enterprises (collectively, the "Shareholders"). C&W is an international
telecommunications company with revenues of L5.5 billion for the fiscal year
ended March 31, 1996 and operations in over 50 countries including the United
Kingdom, Hong Kong, Australia, Colombia and certain Caribbean countries. Itochu
is one of the largest Japanese trading companies with operations in
approximately 90 countries throughout the world, including the United States and
Colombia. In addition, the Company's local shareholders include Empresas
Departamentales de Antioquia (providing telephone services to 102 municipalities
in Antioquia), Telearmenia (a telecommunications company in the city of
Armenia), and Empresas Municipales de Cali, Empresas Publicas de Medellin, de
Manizales and de Pereira (public utility companies providing electric power,
water, telecommunications and gas distribution to Cali, Medellin, Manizales and
Pereira, respectively). Approximately 78% of the Company's capital stock is
beneficially owned by private-sector companies and 22% is beneficially owned by
public sector entities. As of March 31, 1996, the Shareholders had contributed
Ps 96.6 billion (US$115.0 million based on the Representative Market Rate on the
date of each contribution) of equity capital to the Company. The Shareholders
have also provided substantial technical, financial and other expertise to the
Company, and a C&W executive was seconded to, and is employed by, the Company as
a member of the Company's senior management team.
 
THE COLOMBIAN CELLULAR INDUSTRY
 
     Colombia's cellular industry was launched in early 1994, when the Colombian
government conducted a public auction to grant a limited number of long-term
concessions to operate cellular telecommunications networks. For this purpose,
Colombia was divided into three regions: (i) the Western Region, (ii) the
eastern region, which includes Santafe de Bogota, the capital of Colombia (the
"Eastern Region"), and (iii) the Atlantic coast region, which includes the
cities of Barranquilla, Cartagena and Santa Marta (the "Atlantic Region" and
together with the Western Region and the Eastern Region, the "Regions"). The
government awarded a total of six concessions, with two concessions on two
frequencies (the "A Band" and "B Band") in each of the Regions, as follows:

</TABLE>
 
     The densely populated Western Region, for which Occel has one of the two
concessions, encompasses 18% of the territory of Colombia and 36% of its
population. The Western Region contributes approximately 36% of Colombia's gross
domestic product (based on 1993 data) and encompasses a large portion of the
nation's commerce and manufacturing and agricultural industries, including many
of the main export-oriented industries of Colombia, such as coffee, bananas,
sugar and textiles. In addition, the Western Region has an extensive
transportation infrastructure, which includes four major airports and Colombia's
most important industrial seaport, the Buenaventura Port, which handles
approximately half of Colombian exports.
 
     The Company believes that Colombia is a very attractive market for cellular
services and provides a substantial business opportunity for the following
reasons:
 
          - Stable, Growing Economy.  Colombia is one of the oldest democracies
     and most stable economies in Latin America. Since 1950, Colombia has
     enjoyed positive real economic growth in every year, with real compounded
     average annual growth in its GDP of approximately 4.5% from 1986 to 1995,
     one of the highest growth rates in Latin America. In addition, annual
     inflation has declined steadily in each of the past five years from 26.8%
     in 1991 to 22.6% and 19.5% in 1994 and 1995, respectively. In recent years,
     the government's economic growth strategy has encouraged foreign investment
     and exports through reduced foreign exchange controls and lower import
     quotas and tariffs. The government has also begun to open certain public
     services to private sector investment and has commenced privatization of
     certain state-owned industries in the power and banking sectors, and is
     considering other sectors for privatization.
 
                                        6
<PAGE>   11
 
     In part as a result of these policies, foreign investment in Colombia has
     grown from US$3.5 billion in 1990 to US$6.6 billion in 1995. During the
     same period, Colombia has achieved increased diversification of its export
     base and the value of its exports has grown from US$6.7 billion to US $9.8
     billion. However, Colombia is currently experiencing political turmoil
     which could have an adverse effect on the economy. See "Risk
     Factors -- Risk Related to Colombian Political, Economic and Social
     Factors".
 
          - High Demand Potential.  The Company believes there is significant
     demand for cellular service in Colombia as evidenced by the growth in the
     number of subscribers since the concessions were awarded in 1994. Reported
     subscribers in Colombia grew from 81,895 as of December 31, 1994 to 187,514
     as of June 30, 1995 and 274,590 as of December 31, 1995, representing
     growth rates of 129% and 46% for the respective six-month periods. As of
     December 31, 1995, cellular penetration (based on reported subscribers) in
     Colombia was 0.78%. This compares favorably with penetration rates achieved
     at comparable developmental stages in other Latin American countries and a
     penetration rate of 12.96% in the United States. See "Business -- Colombian
     Telecommunications Industry". The Company believes that there are several
     factors, in addition to the recent growth in Colombia's economy and
     particularly its infrastructure, which will support continued growth in
     cellular subscribers. For example, Colombia has a low wireline penetration
     rate, with an average of only approximately ten telephone lines per 100
     persons as of December 31, 1994. Additionally, there is typically a long
     waiting time for wireline telephone connection, which ranges from a few
     weeks or months in the best markets (including Medellin) to two years or
     longer. This can be contrasted with cellular service, where, in the case of
     the Company, new customers generally are connected to its cellular network
     within a few days (shortly after the completion of a credit check).
     Moreover, the Company believes that cellular service is popular even where
     wireline service is relatively good because of advantages such as
     convenience, personal safety and mobility. This is illustrated by the fact
     that Medellin, which has the highest wireline penetration rate in the
     country, is also the Company's best market.
 
          - Limited Cellular Competition.  The Company faces limited cellular
     competition because the cellular industry in each Region is a regulated
     duopoly. Each concessionaire has the exclusive right for a minimum of ten
     years to use a defined frequency band within its region. The terms of the
     concessions provide that the government may not award additional
     concessions for cellular services prior to 1999.
 
          - Supportive Regulatory Environment.  The Colombian government has
     adopted several policies and practices that the Company believes will help
     stimulate industry growth. These include the fact that the concessions are
     limited to two operators per region through 1999 and are awarded for terms
     of ten years, subject to renewal as described herein. The government has
     also mandated a "calling party pays" system which requires that the
     originator pay for the call. The Company believes that the policy of
     calling party pays has resulted in a much higher percentage of incoming
     traffic and more usage overall by its subscribers as they are more likely
     to give their telephone number to callers since they are not charged for
     the incoming call. The policy also encourages subscribers to keep their
     phones turned on. In addition, the government does not currently regulate
     pricing, although the Company is required to notify the government and its
     subscribers of price changes.
 
          - Industry Cooperation.  The Company and other Colombian cellular
     phone operators benefit from government policies which permit industry
     cooperation to facilitate high quality, nationwide service. Through roaming
     and other agreements, the Company and the other A Band operators in the
     Eastern and Atlantic Regions have formed "REDCEL", a national cellular
     network which enables their respective subscribers to make calls from each
     other's coverage areas. These companies also cooperate on issues of common
     interest including, among other things, customer service, collections,
     technical assistance, other services to customers and procedures for fraud
     prevention.
 
COMPANY STRENGTHS
 
     Since its inception in 1992, the Company has capitalized on the market
opportunity created by the aforementioned factors. The Company has constructed a
network that covers most of the major population areas in the Western Region,
built its subscriber base and recognition of its "Vozavoz" brand name, and
developed a variety of service offerings to appeal to diverse groups of
consumers. The Company believes that it
 
                                        7
<PAGE>   12
 
is well positioned to achieve continued growth in its subscriber base and cash
flow by virtue of a number of factors, including the following:
 
          - Attractive Concession Area.  The Western Region has many
     characteristics which create an attractive cellular market, including
     principally a diverse and well developed economy. The region generates over
     one third of Colombia's gross national product and includes a substantial
     part of the country's commerce and manufacturing and agricultural
     industries. Approximately 71% of the national coffee production and 55% of
     the national banana production, the country's two largest agricultural
     commodities, are produced in the Western Region. Approximately half of
     Colombia's hydro-electric power is produced in the Western Region and
     approximately half of the country's exports pass through the Western
     Region's Buenaventura Port. The Western Region also houses the Colombian
     headquarters of 21 of the top 50 industrial and commercial companies in
     Colombia, including Carvajal S.A., Noel S.A. and Colgate Palmolive y Cia
     S.A. In addition, the headquarters of 11 of the top 25 financial
     institutions in Colombia, including Banco Industrial Colombiano S.A.,
     Conavi S.A. and Banco Popular S.A., are located in the Western Region.
 
          - Favorable Demographics.  The metropolitan areas of Medellin and
     Cali, with populations of 2.4 million and 1.8 million, respectively, are
     major economic centers in the country, are densely populated and have
     significant concentrations of affluence. The Company has experienced
     considerable demand in these areas despite their relatively high wireline
     penetration rates. The Company believes this reflects the advantages of
     cellular service, such as personal safety, convenience and mobility, to
     diverse segments of the population, including professional workers as well
     as small businessmen, contractors and other tradesmen who work on location.
 
          - Superior Customer Service.  The Company believes that quality of
     customer service is a key competitive factor in the Colombian duopolistic
     market. The provision of excellent customer service is an essential element
     in the Company's business strategy and an inherent part of its corporate
     culture. Staff in all areas of the Company attend a five-day customer
     service training program, and the Company's specialized customer service
     team (consisting of 91 members as of March 31, 1996) provide service 24
     hours per day, responding to telephone queries from three regional centers.
     On average, the customer service team answers 2000-3000 calls per working
     day (74.2% within 20 seconds in March 1996) and answers 1000 letters per
     month. New customers generally receive service within a few days, as well
     as individual welcome calls to confirm that they are not experiencing
     problems. The Company's dedication to customer service is also illustrated
     by the provision of its free "*911" emergency service and by the provision
     of nationwide service through roaming agreements.
 
          - High Quality Advanced Network.  Due to the recent development of the
     cellular telecommunications industry in Colombia, Occel has been able to
     construct a dual analog/digital network from inception using state of the
     art technology under a TDMA platform with equipment supplied by Northern
     Telecom. The Company believes a significant component of offering the
     highest quality of customer service entails providing its customers
     continual access to its network. The Company measures this in terms of the
     customers' ability to make a call whenever desired and the probability that
     a call will not fail (a "dropped call") once it is connected. During the
     six-month period ended March 31, 1996, the Company connected more than 97%
     of attempted calls and dropped less than 3% of total calls made. The
     Company believes its dual analog/digital network provides it with the
     ability to quickly and cost-effectively offer more digital capacity in its
     network as the demand for digital service increases without incurring the
     problems and costs experienced by many North American operators who are
     encountering operational difficulties and significant expenses as they seek
     to upgrade their networks to digital. As of March 31, 1996, approximately
     30% of the Company's subscribers used digital handsets and the Company
     expects that more than half of its customers will be using digital
     equipment by the end of 1997. The Company expects to realize significant
     benefits from increasing the usage of digital equipment, such as increased
     system capacity, reduced operating expenses and additional revenue from the
     sale of digital-specific services such as "caller i.d." and voice mail
     message waiting notification. The Company believes its network has
     sufficient capacity to accommodate projected growth in subscribers and has
     the flexibility to handle new services.

          - Numerous Service Offerings.  The Company provides the basic cellular
     service options offered by world class operators, such as call transfer,
     call waiting, voice mail and national and international roaming. In
     addition, the Company offers several other services that are aimed at the
     particular needs of its customer base and that enhance the Company's brand
     name and image as a provider of the highest quality service. These include
     its free "*911" emergency service (which is trademarked within Colombia),
     where a customer can call *911 at any time and be connected to a Company
     representative who can then contact the police, the fire department, an
     automobile towing service or any other emergency service desired by the
     customer. This service has proved especially popular because the Colombian
     wireline companies do not have a universal emergency service such as the
     911 service in the United States. The Company also offers value-priced
     services that it believes attract different segments of the population than
     traditional users of cellular services, thereby enhancing its penetration
     rate. The Company offers "Beepervoz", a budget service in which the
     customer can only receive calls and make outgoing calls to the Company's
     *911 emergency service. This service provides a low-cost introduction to
     cellular service and is also designed to compete with pagers. In addition,
     the Company's "Fijovoz" service provides cellular service from a fixed
     wireless phone in the home or office for a lower price than its mobile
     cellular service. This option is designed to appeal to customers seeking to
     avoid the long waiting time for wireline service or who are otherwise
     dissatisfied with wireline service but who do not need the mobility of full
     cellular service. The Company also believes a number of these
     budget-conscious customers will ultimately upgrade to higher classes of
     service over time.
 
          - Management of Churn.  The Company's monthly average churn rate for
     the year ended December 31, 1995, was 3.2%. This reflected a churn rate of
     approximately 2% per month for most of the year, except between August and
     October when churn was approximately 8% per month. This temporary increase
     in churn resulted from Company-initiated disconnections in order to upgrade
     the quality of its customer base. The Company estimates that the monthly
     churn rate for the first six months of 1996 averaged 2.9%, in part because
     there was a similar month of Company-initiated disconnections, which may
     occur from time to time in the future. The Company recognizes that managing
     customer churn is an important factor in maximizing revenues and cash flow.
     In order to minimize churn caused by customers voluntarily terminating
     service, the Company aims to ensure that its services remain competitive
     and has one-year customer contracts that contain penalties for early
     termination. To reduce Company-initiated disconnections resulting from
     non-payment, beginning in August 1995, the Company implemented policies
     which require thorough credit checks for new customers, encourage direct
     debit payment plans, and impose gradual restrictions on service once
     payment dates have been missed. For instance, customers' outgoing calls are
     automatically routed to customer service if payment is not received within
     ten days of the final due date, and service is temporarily disconnected in
     the event payment is not received within ten more days. The Company
     believes that these policies reduce the likelihood that customers will run
     up excessive debts, thus enhancing the likelihood of settlement and
     reconnection.
 
          - Experienced Management Team.  The members of the Company's senior
     management team have substantial experience in the telecommunications
     industry as well as in the public and private sectors in the Western
     Region. Many of them worked for local telephone companies and public
     utilities in the Western Region and participated in the development of
     Colombia's cellular regulatory regime. In addition, an executive of C&W,
     was seconded to, and is employed by, the Company as a member of the
     Company's senior management.
 
BUSINESS STRATEGY
 
     The Company's strategy is to continue to capitalize on the high potential
demand for cellular telecommunication services and favorable demographic
characteristics of its concession area to maximize revenues and cash flow from
its cellular business through increased market penetration and subscriber usage.
The Company intends to achieve these objectives by completing construction of
its network, implementing aggressive marketing efforts to attract and retain
additional subscribers and continuing to provide superior customer service,
reliability and a wide range of value-added optional services. The Company's
commercial slogan is "Seriousness, Security and Service", which is intended to
convey the high degree of professionalism with which the Company seeks to
provide its services, the security (i.e., increased personal safety) such
services provide to its customers, and the Company's responsiveness to its
customers. The Company will also evaluate and may participate in future
opportunities in related wireless technology businesses in order to enhance its
position as a leading provider of such services.

                                THE REFINANCING
 
     The Old Notes were issued on June 7, 1996 pursuant to the Offering of
190,745 units (the "Units"), each of which consisted of US$1,000 principal
amount at maturity of Old Notes and four warrants to purchase 5.709 shares of
Class B Common Stock with a par value of 1,000 Pesos per share, at a price of
US$1.00 per share (or, if greater, the U.S. dollar equivalent of 1,000 Pesos),
subject to adjustment (the "Warrants"). The Old Notes and the Warrants will
become separately transferable as of the date of this Prospectus.
 
     Concurrently with the issuance of the Units, the Company borrowed US$80.0
million under the Bank Facility (as defined under "Description of Company
Indebtedness -- Bank Facility"), which loans are secured by security interests
in, among other things, (i) all receivables originated from the provision of
cellular communications and roaming and interconnection services, (ii) the
pledge of 99.99% of the Company's outstanding stock, and (iii) the Concession.
The aggregate net proceeds of the Offering and the borrowings under the Bank
Facility were US$171.5 million. Such net proceeds were used to repay
substantially all existing indebtedness of the Company and for working capital.
See "Description of Company Indebtedness -- Bank Facility".

Federal Income Tax
  Consequences.............  The exchange of Notes pursuant to the Exchange
                             Offer will not be a taxable event for federal

Warrants Not Part

                             Units each consisting of US$1,000 principal amount
                             at maturity of Old Notes and the Warrants. The
                             Warrants are not part of the Exchange Offer and
                             should not be tendered to the Exchange Agent. As of
                             the date of this Prospectus, the Old Notes and the
                             Warrants are separately transferable.
 
CONSEQUENCES OF EXCHANGING OLD NOTES PURSUANT TO THE EXCHANGE OFFER
 
     Based on certain interpretive letters issued by the staff of the SEC to
third parties in unrelated transactions, holders of Old Notes (other than any
holder who is an "affiliate" of the Company within the meaning of Rule 405 under
the Securities Act) who exchange their Old Notes for New Notes pursuant to the
Exchange Offer generally may offer such New Notes for resale, resell such New
Notes, and otherwise transfer such Notes without compliance with the
registration and prospectus delivery provisions of the Securities Act provided
such New Notes are acquired in the ordinary course of the holders' business and
such holders are not participating in, and have no arrangement or understanding
with any person to participate in, a distribution of such New Notes. Each
broker-dealer that receives New Notes for its own account in exchange for Old
Notes, where such Old Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such New Notes. See
"Plan of Distribution". If a holder of Old Notes does not exchange such Old
Notes for New Notes pursuant to the Exchange Offer, such Old Notes will continue
to be subject to the restrictions on transfer contained in the legend thereon.
In general, the Old Notes may not be offered or sold, unless registered under
the Securities Act, except pursuant to an exemption from, or in a transaction
not subject to, the Securities Act and applicable state securities laws. See
"The Exchange Offer -- Consequences of Failure to Exchange; Resale of New
Notes".
 
     The Old Notes are currently eligible for trading in the Private Offerings,
Resales and Trading through Automated Linkages ("PORTAL") market. Following
commencement of the Exchange Offer but prior to its consummation, the Old Notes
may continue to be traded in the PORTAL market. However, to the extent that Old
Notes are tendered and accepted in connection with the Exchange Offer, any
trading market for remaining Old Notes will be adversely affected. Following
consummation of the Exchange Offer, the New Notes will not be eligible for
PORTAL trading.
 
                                 THE NEW NOTES
 
     The terms of the New Notes are identical in all material respects to the
Old Notes, except for certain transfer restrictions and registration rights
relating to the Old Notes.

                             to the date of redemption, provided that no less
                             than 67% of the original aggregate principal amount
                             at maturity of the New Notes remains outstanding.
                             The New Notes will be redeemable at the option of
                             the Company, as a whole, but not in part, in the
                             event of certain changes in Colombian tax law. The
                             Company's ability to redeem the New Notes is
                             subject to certain limitations under Colombian law.
                             See "Description of the Notes -- Optional

                             amount thereof.
 
Colombian Withholding
Taxes......................  Interest on the New Notes, including the accretion
                             of value thereof, is not currently subject to
                             Colombian Withholding Taxes (as defined herein).
                             See "Taxation -- Colombia".
 
Additional Amounts.........  Subject to limited exceptions, if Colombian
                             Withholding Taxes are deducted or withheld from
                             payments on the New Notes, the Company will pay
                             Additional Amounts (as defined herein) to the
                             extent necessary so that, after such deduction or
                             withholding, holders of the New Notes receive the
                             stated amount due. Currently, no Additional Amounts
                             are required to be paid. See "Description of the
                             Notes -- Additional Amounts" and

                             require the Company to purchase all or a portion of
                             such holder's New Notes at a purchase price in cash
                             equal to 101% of the Accreted Value thereof,
                             together with accrued and unpaid interest, if any,
                             to the date of purchase. The Company's ability to
                             purchase New Notes upon the occurrence of a Change
                             of Control is subject to certain limitations under
                             Colombian law. See "Description of the
                             Notes -- Certain Covenants -- Purchase of Notes
                             upon a Change of Control".
 
Ranking....................  The New Notes will be senior unsecured obligations
                             of the Company, ranking pari passu in right of
                             payment with all other existing and future
                             unsubordinated obligations of the Company (other
                             than obligations preferred by statute or by
                             operation of law), except to the extent the
                             provisions of the Indenture require the Trustee to

                             Company until all claims under the Bank Facility
                             are satisfied during the period from the Issue Date
                             until the restriction on the right of the Lenders
                             to exercise their remedies under the pledge of the
                             Concession expires, and senior in right of payment
                             to all existing and future obligations of the
                             Company expressly subordinated in right of payment
                             to the New Notes. The New Notes, however, will be
                             effectively subordinated to senior secured
                             obligations of the Company with respect to the
                             assets of the Company securing such obligations,
                             including Indebtedness under the Bank Facility
                             which is secured by, among other things, (i) all of
                             the Company's receivables originated from the
                             provision of cellular communications and roaming
                             and interconnection services and (ii) the pledge of
                             the Concession to operate its business, provided
                             that the Lenders may not exercise any remedies
                             thereunder prior to March 28, 1997. The
                             Indebtedness under the Bank Facility is also
                             secured by a pledge of 99.99% (as of the date
                             thereof) of the Company's outstanding common stock.
                             See "Description of Company Indebtedness -- Bank
                             Facility". As of June 30, 1996, Indebtedness of the
                             Company was approximately US$181.8 million, of
                             which US$80.0 million was senior secured
                             Indebtedness and US$101.8 million was senior
                             unsecured Indebtedness. Subject to certain
                             limitations, the Company and any Restricted
                             Subsidiary (as defined herein) may incur additional
                             Indebtedness, including secured Indebtedness, in
                             the future.
 
Original Issue Discount....  Both the Old Notes and the New Notes will be
                             treated as having been issued at an original issue
                             discount for United States federal income tax
                             purposes. Thus, although cash interest will not
                             begin to accrue on the Notes until March 15, 2001,
                             and there will be no periodic payments of interest
                             on the Notes prior to September 15, 2001, original
                             issue discount (i.e., the difference between the
                             stated redemption price at maturity and the portion
                             of the issue price of the Units allocated, for
                             federal income tax purposes, to the Notes) will
                             accrue from the Issue Date and will be includible
                             as interest income periodically in a Note holder's
                             gross income for federal income tax purposes in
                             advance of receipt of the cash payments to which
                             the income is attributable. See "Taxation -- United
                             States".
 
Restrictive Covenants......  The Indenture (as defined herein) contains certain
                             covenants, including, but not limited to, covenants
                             with respect to the following matters: (i)
                             limitation on indebtedness; (ii) limitation on
                             restricted payments; (iii) limitation on issuances
                             and sale of capital stock of restricted
                             subsidiaries; (iv) limitation on transactions with
                             affiliates; (v) limitation on liens; (vi)
                             limitation on sale of assets; (vi) limitation on
                             sale and leaseback transactions; (vii) limitation
                             on the activities of the Company; (viii) limitation
                             on dividends and other payment restrictions
                             affecting subsidiaries; and (ix) reports. See
                             "Description of the Notes -- Certain Covenants".
 
Absence of a Public Market
for the New Notes..........  The New Notes are new securities and there is
                             currently no established market for the New Notes.
                             Accordingly, there can be no assurance as to the
                             development or liquidity of any market for the New
                             Notes. The

                      SUMMARY FINANCIAL AND OPERATING DATA
 
     The Company was incorporated in 1992 and commenced offering commercial
cellular services in September 1994. Accordingly, the Company has no commercial
operating history prior to such time, and results for 1994 are not directly
comparable to those of 1995. The summary statement of operations data for each
of the fiscal years ended December 31, 1993, 1994 and 1995, and the summary
balance sheet data as of December 31, 1994 and 1995 are derived from financial
statements which are prepared in accordance with Colombian generally accepted
accounting principles and which have been audited by KPMG Peat Marwick,
independent auditors. The historical information for the three months ended
March 31, 1995 and 1996 has been derived from the unaudited financial statements
of the Company included herein. In the opinion of management, the information
for the three months ended March 31, 1995 and 1996 includes all material
adjustments (consisting only of adjustments of a normal and recurring nature)
necessary for a fair presentation of the results for such periods. The results
of operations for any interim period are not necessarily indicative of the
results of operations for a full year. Colombian generally accepted accounting
principles differ in certain significant respects from United States generally
accepted accounting principles. See note 17 to the financial statements of the
Company included elsewhere in this Prospectus. This information should be read
in conjunction with, and is qualified in its entirety by reference to,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the financial statements of the Company, including the notes
thereto, included elsewhere in this Prospectus.

     generally accepted accounting principles), because it understands that it
     is used by certain investors as one measure of an issuer's ability to
     service or incur indebtedness. EBITDA should not be construed as an
     alternative to operating income (as determined in accordance with generally
     accepted accounting principles) as an indicator of the Company's
     performance or to cash flows from operating activities (as determined in
     accordance with generally accepted accounting principles) as a measure of
     liquidity. EBITDA is calculated using financial statement information
     included herein and, accordingly, is in constant Colombian pesos and
     includes inflation adjustments.
 
 (6) The ratio of earnings to fixed charges covers continuing operations, and
     for this purpose (i) earnings consist of income (loss) before income taxes
     plus fixed charges and (ii) fixed charges consist of interest expense on
     all debt (including capitalized interest), amortization of deferred
     financing costs and a percentage of rental expense deemed to be interest.
     There were no fixed charges in 1993. Earnings were inadequate to cover
     fixed charges in 1994 and 1995 and in the three months ended March 31, 1995
     and 1996. The fixed charge coverage deficiency for the years ended December
     31, 1994 and 1995 amounted to Ps 3.1 billion (US$3.0 million) and Ps 43.8
     billion (US$41.8 million), respectively. The fixed charge coverage
     deficiency for the three months ended March 31, 1995 and 1996 amounted to
     Ps 7.9 billion (US$7.6 million) and Ps 4.8 billion (US$4.6 million),
     respectively.
 
 (7) Pro forma for the issuance of the Notes and the borrowings under the Bank
     Facility and application of the proceeds thereof as if the same occurred at
     the beginning of the periods shown. Pro forma cash interest expense is
     based on an assumed annual interest rate of 9.25% applied to an outstanding
     balance of US$80 million under the Bank Facility and an average rate of
     8.7% on an average letter of credit balance of US$3 million. Pro forma
     total interest expense consists of the accretion on the Notes and the pro
     forma cash interest expense. Numbers for the year ended December 31, 1995
     do not give effect to constant Peso adjustments.

                                  RISK FACTORS
 
     Holders of Old Notes should consider carefully all the information set
forth herein and, in particular, the following risks in connection with the
Exchange Offer. For additional information concerning Colombia and certain
matters discussed below, see "Annex B -- Republic of Colombia". In general,
investing in the securities of issuers in emerging markets such as Colombia
involves a higher degree of risk than investing in the securities of issuers in
the United States and other jurisdictions.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon as a
consequence of the issuance of the Old Notes pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities Act
and applicable states securities laws. In general, the Old Notes may not be
offered or sold, unless registered under the Securities Act, except pursuant to
an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. The Company does not currently anticipate that
it will register Old Notes under the Securities Act. See "The Exchange
Offer -- Consequences of Failure to Exchange; Resale of New Notes".
 
POSSIBLE LIMITATIONS ON SALE OF NEW NOTES
 
     To comply with the securities laws of certain jurisdictions, if applicable,
the New Notes may not be offered or sold unless they have been registered or
qualified for sale in such jurisdictions or an exemption from registration or
qualification is available and is complied with. The Company has agreed to
register or qualify the sale of the New Notes in such jurisdictions only in
limited circumstances and subject to certain conditions. See "The Exchange
Offer -- Consequences of Failure to Exchange; Resale of New Notes".
 
HIGH LEVERAGE AND ABILITY TO SERVICE DEBT
 
     The Company is highly leveraged. As of June 30, 1996, the Company's total
indebtedness was US$181.8 million or, approximately 69% of its total
capitalization. The Exchange Offer will not increase or decrease the Company's
total indebtedness.
 
     The Company's high degree of leverage will have important consequences to
holders of the Notes, including the following: (i) the ability of the Company to
obtain additional financing in the future for working capital, capital
expenditures, acquisitions or other purposes, may be impaired; (ii) a
substantial portion of the Company's cash flow from operations will be required
to be dedicated to meet the Company's debt service obligations, which will
reduce the funds available to the Company for its operations and future business
opportunities; (iii) the Company may be more highly leveraged than its
competitors which may place it at a competitive disadvantage; (iv) the Company's
high degree of leverage may make it more vulnerable to a downturn in its
business and may limit its ability to respond to price competition or changes in
the economy generally; (v) the Company may not have sufficient funds to repay
the Notes at maturity or may not be able to refinance the indebtedness
thereunder at maturity; and (vi) the Company's ability to invest in or develop
new technologies or take advantage of new opportunities may be restricted.
 
     The ability of the Company to meet its debt service obligations will depend
on the future operating performance and financial results of the Company
(requiring a significant and sustained growth in cash flow), which will be
subject in part to factors beyond the control of the Company, such as prevailing
economic conditions and financial, business and other factors. Management
believes that the Company's cash flow from operations will be adequate to meet
its anticipated requirements for working capital, capital expenditures, interest
payments and scheduled principal payments. There can be no assurance, however,
that the Company's business will generate cash flow at the necessary levels. If
the Company is unable to generate sufficient cash flow from operations in the
future to service its debt, it may be required to reduce capital expenditures,
refinance all or a portion of its existing debt (including the Notes), or obtain
additional financing. There can be no assurance that any such refinancing would
be possible or that any additional financing can be obtained on satisfactory
terms, in which case the Company might not be able to meet its obligations under
the Notes.

RISKS RELATED TO COLOMBIAN POLITICAL, ECONOMIC AND SOCIAL FACTORS
 
     Colombia is currently experiencing political turmoil stemming principally
from allegations that President Samper's 1994 election campaign received
contributions from the Cali drug cartel. On December 15, 1995, the Congressional
committee that had been examining evidence of such allegations ruled that there
was insufficient evidence to open a formal investigation against President
Samper. However, on January 22, 1996, the campaign manager and former Minister
of Defense, who (together with two other senior campaign officials) was arrested
in connection with such allegations, made a public statement alleging that
contributions from the Cali drug cartel had, in fact, been received and that
President Samper was aware of them. Consequently, the Attorney General's Office
formally accused the President before Congress and a new investigation began.
This investigation concluded last June with the Congress' decision to preclude
the process against President Samper, as recommended by the Congressional
committee in charge of the investigation. This political crisis has had and may
continue to have an adverse effect on the country's economy. Industry
associations have reported declines in sales, investments and other economic
activities. Many of the country's business leaders have called on President
Samper to resign. Although the crisis has not led to repeal of the actions taken
in recent years to open and liberalize the economy, it has weakened the
government and could result in a change in government. This in turn could lead
to a change in public policy generally regarding economic development and the
economy.
 
     The political crisis has occurred against a backdrop of periodic violence
related to both drug activities and guerilla movements in Colombia and was
aggravated by the announcement by President Clinton on March 1, 1996 that the
United States was "decertifying" Colombia for failing to take sufficient action
to stem the production and export of narcotics. Under United States law, the
President was required to certify to the U.S. Congress which nations that are
major producers or major transit points for drugs were cooperating with efforts
to stem the flow of narcotics into the United States. As a result of such
decertification, the following policies are in effect: (i) the United States
representatives on the boards of certain multilateral development banks, such as
the International Bank for Reconstruction and Development and the Interamerican
Development Bank, are instructed to vote against lending to Colombia, (ii) the
United States government may impose trade sanctions on Colombian products
exported to the United States and (iii) United States credit institutions, such
as the Export-Import Bank and the Overseas Private Investment Corporation, will
not lend funds, or issue insurance (including political risk insurance), for
Colombian projects. For example, subsequent to President Clinton's announcement,
the Export-Import Bank withdrew support for a US$296 million loan to Ecopetrol,
the state-owned oil company, intended to help finance the Cusiana Oil pipeline,
a major development project in Colombia. On July 11, 1996, the United States
government announced the cancellation of President Samper's visa to enter the
United States based on the allegation that Mr. Samper had cooperated with
illegal drug traffickers. Although the United States has not imposed further
sanctions at this time, there can be no assurance that additional sanctions will
not be imposed in the future.
 
     For the past 40 years, various guerrilla groups have waged campaigns
against the Colombian governmental system. The actions of guerilla groups have
included terrorist attacks, kidnapping and extortion. There is no assurance that
continued guerrilla activity will not have a material adverse effect on the
general economic, social or political situation in Colombia and the Company's
operations, in particular.
 
     Medellin and Cali have been the centers of operations of Colombia's most
powerful drug cartel groups and are also the Company's largest markets. These
areas have suffered from the violence and the costs of attempting to curb the
drug trade, but may also have benefitted from the capital generated by it, to
the extent reinvested locally. The Company believes that its business has
historically not been materially adversely affected either by the drug activity
or by efforts to curb it. However, no assurance can be given that drug activity
in the future will not materially adversely affect the Company or that the
efforts to curb such activity will not have an adverse effect on the economy of
the region and thereby on the Company.
 
     It is impossible to predict what effect these events and conditions, which
are entirely outside the control of the Company, will have on the country or the
Company. Holders of the Notes should recognize that these
 
                                       18
<PAGE>   23
 
conditions and events create significant uncertainties and risks, which could
result in material adverse effects on the Company and its ability to meet its
obligations, including obligations under the Notes.
 
INFLATION
 
     Throughout most of the 1980s and 1990s, Colombia experienced high levels of
inflation. While the Colombian government adopted policies which resulted in
reducing the inflation rate from 26.8% in 1991 to 22.6% and 19.5% in 1994 and
1995, respectively, there can be no assurance that the performance of the
Colombian economy or its securities markets, the operating results of the
Company or the value of the Notes will not be adversely affected by continuing
or increased levels of inflation.
 
LIMITED OPERATING HISTORY; OPERATING LOSSES
 
     The Company is a new enterprise. The Company was incorporated in 1992 and
commenced offering commercial cellular services in September 1994. Since such
commencement date, the Company has experienced cumulative net negative cash flow
resulting principally from high operating expenses associated with the start up
of the Company's business, as well as cumulative net losses resulting from the
foregoing. Although the Company expects to generate positive cash flow from
operations by 1997, it expects to incur net losses in the near-term. There can
be no assurance that the Company will achieve positive cash flow from operations
within its projected time frame, or that it will generate net income upon
completion of its network.
 
CURRENCY FLUCTUATIONS, FOREIGN EXCHANGE CONTROLS AND DEVALUATION
 
     Substantially all of the Company's debt obligations are denominated in
Dollars while the Company generates revenues in Pesos. In addition, the Company
has incurred and expects to incur a significant portion of its equipment costs
in Dollars. Therefore, the Company is exposed to currency exchange rate risks
which could significantly impact the Company's ability to meet its obligations
and finance its network construction. The Company currently does not plan to
enter into hedging transactions with respect to these foreign currency risks and
it is unlikely that the Company would be able to obtain hedging arrangements on
commercially satisfactory terms with respect to all such risks. The exchange
rate of the Peso to the Dollar has declined in recent years, and any further
decrease in the value of the Peso relative to the Dollar may have a material
adverse effect on the Company and on its ability to meet its obligations under
the Notes.
 
     The Colombian government does not currently restrict the ability of
Colombian persons or entities to convert Pesos into Dollars. See "Foreign
Investment and Exchange Controls in Colombia". However, Colombian law permits
the government to impose foreign exchange controls on dividend payments and
repatriation of capital in the event that the foreign currency reserves of the
Central Bank fall below a level equal to the value of three months of imports
into Colombia. No such foreign exchange controls are currently applicable to
payments on debt instruments such as the Notes. As of December 31, 1995, the
Central Bank's currency reserves were sufficient for approximately seven months
of imports. Nevertheless, there is no assurance such restrictions will not be
imposed in the future, and any such restrictions could prevent or restrict the
Company's access to Dollars with which to meet its obligations, including its
obligations under the Notes.
 
     Colombian law prohibits the prepayment of the Notes within one year of
their issuance, whether by redemption, repurchase, acceleration or otherwise.
Any redemption, repurchase, acceleration or other event requiring repayment
occurring on or prior to the first anniversary of the Issue Date will require
the Company, in lieu of such redemption, repurchase, acceleration or other
prepayment, to deposit with the Trustee cash and/or United States Government
Obligations in an amount (without taking into account the payment of interest
thereon) sufficient to make such prepayment with respect to the Notes on the
first Business Day after the first anniversary of the Issue Date at a price
which the Company would have had to pay with respect to such a prepayment
occurring on the first anniversary date, provided that in the event of an offer
to purchase under a Change of Control, the Company would have to deposit with
the Trustee an amount (without taking into account the payment of interest
thereon) sufficient to repurchase all of the Notes.
 
     Central Bank regulations require that, as a general rule, borrowers
incurring indebtedness in a foreign currency with a term of 36 months or less
make deposits in Pesos at the Central Bank in order to be able to
 
                                       19
<PAGE>   24
 
remit payments in such foreign currency. As the scheduled repayment of the Notes
will begin after the third anniversary of the Issue Date, the Company does not
currently have an obligation to make such a deposit. However, if the Company
desires or is required to make a prepayment of the Notes in an amount exceeding
40% of the principal amount thereof prior to the third anniversary of the Issue
Date, the Company would be required to make such a deposit, in which case the
Company may elect to deposit with the Trustee amounts sufficient to redeem the
remainder of the Notes on the first business day after the third anniversary of
the Issue Date. There can be no assurance that the necessary Peso funds for such
a deposit will be available to the Company at the time of any such requirement
to make a prepayment. See "Foreign Investment and Exchange Controls in Colombia"
and "Description of the Notes".
 
ECONOMY OF COLOMBIA AND THE WESTERN REGION
 
     The Company's operations are dependent upon the performance of the
Colombian economy and the Western Region, in particular. The economy of Colombia
and of the Western Region is in a stage of development and structural reform and
the possibility exists that rapid fluctuations in consumer prices, gross
domestic product and interest rates will occur. The Company's financial results
may be subject to such fluctuations in the economy of Colombia and of the
Western Region and the effect of such fluctuations on the ability of customers
to pay for the Company's services and on the ability of the market to support
the growth of cellular telephone operations.
 
     The Colombian government has historically exercised significant influence
over the Colombian economy. Governmental actions concerning the economy could
continue to have an important effect on Colombian entities, including the
Company, and on market conditions, prices and returns on Colombian securities,
including the Notes. There can be no assurance that recent policies that have
resulted in favorable economic growth in Colombia will be maintained by this
government or any new government or that such growth will continue.
 
RISKS ASSOCIATED WITH NEW INDUSTRY AND GROWTH
 
     The success of the Company's operating strategy is subject to factors that
are beyond the control of the Company and impossible to predict, in part because
cellular telecommunications is a new industry in Colombia. Although the Company
has experienced significant growth in the number of its subscribers since
commencing operations in 1994, the Company is unable to predict how consumer
demand for cellular telecommunications services may develop over time. The size
of the Colombian market for cellular telecommunications, the rates of
penetration of the market and the sensitivity of potential subscribers to
changes in prices, among other factors, are uncertain. In addition, the
Company's continued rapid growth will require the training of new personnel, the
expansion of its management information systems and effective control of its
expenses related to operations and systems construction and effective controls
over the quality of new subscribers and churn rate. If the Company is unable to
satisfy these requirements, if it is unable to generate sufficient revenue to
meet its current expenses and future obligations or if it is otherwise unable to
manage growth effectively, the Company's ability to meet its obligations under
the Notes may be materially adversely affected.
 
COMPETITION; RAPID TECHNOLOGICAL CHANGE
 
     The Company faces competition primarily from Cocelco, the other Western
Region cellular operator, and from wireline telephone services. Cocelco's
principal shareholders include the Organizacion Luis Carlos Sarmiento, one of
the largest commercial groups in Colombia, and Telefonica de Espana, a major
Spanish telecommunications organization actively involved in Latin America.
Cocelco may have greater financial and other resources than the Company, and may
be in a better position to fund operating deficits or unexpected capital costs.
Competition in the Western Region between the Company and Cocelco, and to a
lesser extent with wireline telephone services, is based on price, services
offered, quality of service and coverage area. During the first quarter of 1995,
there was significant price competition between the Company and Cocelco, and
there is no assurance that additional periods of price competition will not
follow or that they will not result in substantial operating losses for the
Company. Moreover, there can be no assurance that, in the event of an
 
                                       20
<PAGE>   25
 
aggressive price competition resulting in substantial losses, the Company will
be able to raise the necessary capital or financing to finance such losses. See
"Management Discussion and Analysis of Financial Condition and Results of
Operations". In addition, after March 28, 1999, the fifth anniversary of the
Concession, additional concessions for cellular services in the Western Region
may be granted by the Ministry of Communications which could mean that the
Company would no longer enjoy a duopolistic position in the Western Region.
 
     The Company also faces competition from other existing wireless services,
such as mobile radio and beeper services, and may face competition from emerging
technologies and services which might be introduced in the future, including
enhanced specialized mobile radio, Personal Communication Services ("PCS") or
satellite telephone. Insofar as such services require the granting of new
concessions by the Colombian government, it is possible that the government
could grant such concessions prior to 1999 (i.e., prior to the date that
additional concessions for cellular services in the Western Region may be
granted by the Ministry of Communications). In addition, to the extent that
substantial capital is invested in the wireline telephone industry and results
in improved service and increased wireline density, some of the Company's
existing and potential subscribers may choose wireline service rather than the
Company's cellular services. There can be no assurance that the Company will be
able to compete successfully against existing competitors or new entrants.
 
CHURN RATE RISKS
 
     The Company's churn rate (the rate at which subscribers leave the system,
calculated as a percentage of active subscribers at the end of a calculation
period) in 1995 averaged 2% per month except between August and October when
churn was approximately 8% per month. During the months of August through
October 1995, in order to upgrade the quality of its customer base, the Company
disconnected a number of customers with nonperforming accounts, many of whom
subscribed to the Company's service during promotions offered in the early part
of 1995. The Company estimates that the monthly churn rate for the first six
months of 1996 averaged 2.9%, in part because there was a similar month of
Company-initiated disconnections, which may occur from time to time in the
future. To reduce churn and to deal with its associated risks, such as the
difficulty in collecting receivables, the Company has since implemented more
rigorous customer credit checks, gradual restrictions on service in the event of
nonpayment and other measures to minimize the risk of bad debts. If the Company
is not able to maintain these measures, or is not otherwise able to maintain
churn at a low level, it could have an adverse effect on its financial condition
and may adversely affect its ability to meet its obligations under the Notes.
 
FUTURE CAPITAL NEEDS
 
     The Company expects to increase operating expenses and capital expenditures
as it continues to pursue its strategy of completing the construction of its
network, increasing its existing base of subscribers and expanding its
operations to provide a wider array of value-added services. The Company expects
to incur capital expenditures of approximately US$51 million to substantially
complete by 1999 the build-out of its network (including planned upgrades). The
Company currently expects to fund all of such capital expenditures with
internally generated cash flow, although there can be no assurance that such
cash flow will be sufficient. In addition, if the Company were to decide to
pursue other investments, including PCS or satellite services, additional
resources would be required. If the Company is unable to fund such expenditures
or investments, or if the Company's cash flow from operations does not increase
from its present level or decreases even further, the Company might not be able
to continue to pursue its network construction and subscriber growth strategy.
Moreover, in any such circumstance, the Company could experience difficulty in
meeting its debt service requirements. If the Company were unable to meet its
debt service requirements in the future, it may, depending upon the
circumstances which then exist, seek additional equity and/or debt financing or
refinance its existing indebtedness. There can be no assurance that the Company
could refinance existing indebtedness or raise sufficient funds. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources".
 
                                       21
<PAGE>   26
 
REGULATORY AND CONCESSION MATTERS
 
     The construction, ownership and operation of the Company's cellular
telephone system, the maintenance and renewal of the Concession, the pricing of
the Company's services and related matters are subject to regulation by the
Ministry of Communications and the Colombian Telecommunications Regulatory
Commission (Comision de Regulacion de Telecomunicaciones) (the "TRC"). Changes
in the regulation of, or the interpretation thereof, the Company's activities
could have a material adverse effect on the Company. Although the TRC has the
authority to determine the pricing of cellular services, cellular operators have
not been subject to tariff regulation. The Company believes that cellular
operators will continue to have the flexibility to set prices freely, although
there can be no assurance that the TRC will not impose price regulation in the
future.
 
     The continued existence and terms of the Concession are subject to ongoing
review by regulatory authorities in Colombia and to interpretation, modification
or termination by such authorities. The terms of the Concession provide for an
initial term of ten years, and the Concession may be renewed for another ten
years if the Company has complied with the terms of the Concession and neither
the Ministry of Communications nor the Company has expressed an intention not to
renew during the eighth year of the Concession's ten-year term. The terms and
conditions of any such renewal, including the amount of any necessary payment to
the Colombian government, are not specified. Although the Company intends to
seek amendments to the Concession to eliminate uncertainties regarding renewal,
there is no assurance such amendments can be obtained. While the Company would
not normally expect to be required to cease operations at or prior to the end of
the ten-year term of the Concession, there can be no assurance that the
Concession will not be terminated or that renewal will be effected at all or on
acceptable economical terms.
 
     The Company's assets that are directly related to the Concession are to
revert to the Ministry of Communications at the end of the Concession's term
without compensation to the Company. The Ministry of Communications is also
entitled to a reversion of such assets upon an event of termination of the
Concession for default in performance by the Company. If such reversion were to
occur, it will have a material adverse effect on the Company's ability to meet
its obligations under the Notes. See "Business -- Regulation -- Termination upon
Default in Performance -- Reversion of Assets".
 
     The Concession, as well as certain other Colombian government contracts, is
subject to unilateral interpretation, modification and termination by the
Colombian government under certain circumstances. In the event of such
unilateral interpretation, modification or termination, based on circumstances
not attributable to the Company, the Company would be entitled to compensation
from the Ministry of Communications. However, there can be no assurance that any
such compensation would be sufficient to enable the Company to meet its
obligations under the Notes. See "Regulation -- Unilateral Interpretation,
Modification and Termination of Government Contracts". In addition, the Ministry
of Communications may, without compensation, terminate the Concession for
certain events of default under the Concession; in the event of such
termination, the Ministry of Communications would also be entitled to a payment
by the Company in the amount of the performance bond posted by the Company under
the Concession. See "Regulation--Termination upon Default in Performance". The
Ministry of Communications may also seek payment from the Company for any
damages suffered in excess of the amount covered by such performance bond.
 
ASSET ENCUMBRANCES AND PLEDGE OF STOCK
 
     The Company's obligations under the Bank Facility are secured by liens on
the Company's receivables and a pledge of the Concession, provided that the
Lenders may not exercise any remedies with respect to the pledge of the
Concession prior to March 28, 1997. If an event of default occurs under the Bank
Facility, the Lenders will have a prior right to such collateral and may
foreclose upon such collateral to the exclusion of the holders of the Notes,
notwithstanding the existence of an event of default with respect to the Notes.
Accordingly, in such event, such collateral would first be used to repay in full
amounts outstanding under the Bank Facility, and there can be no assurance that
there would be sufficient assets remaining to satisfy the claims of holders of
the Notes.
 
                                       22
<PAGE>   27
 
     For the period until the restriction on the right of the Lenders to
exercise their remedies under the pledge of the Concession expires, the
Indenture provides that should the Company enter into a bankruptcy
reorganization (concordato) or liquidation under the laws of Colombia during
such period, the Trustee will turn over to the collateral agents for the lenders
under the Bank Facility all amounts that constitute proceeds of the Concession
received pursuant to a bankruptcy reorganization (concordato) or liquidation of
the Company until all claims under the Bank Facility are satisfied. The
Shareholders have also pledged substantially all of the capital stock of the
Company to the Lenders. If an event of default occurs under the Bank Facility,
the Lenders could foreclose upon such stock, which could result in a change of
control of the Company.
 
RESTRICTIONS UNDER DEBT INSTRUMENTS
 
     The Company's operations and financial performance are subject to covenants
contained in the Bank Facility and the Indenture that, among other things, limit
the Company's ability to incur liens, incur additional indebtedness, dispose of
assets, engage in mergers or engage in certain other transactions, and redeem or
purchase the Notes. In addition, the Bank Facility requires the Company to
maintain certain financial ratios and to meet certain financial and operating
performance tests. There can be no assurance that these requirements will be met
in the future. If the covenants under the Bank Facility are not met, the Lenders
will be entitled to declare such indebtedness immediately due and payable. See
"Description of the Notes" and "Description of Company Indebtedness".
 
TAX LITIGATION
 
     The Company is currently in litigation with the tax authorities of Medellin
with respect to the municipality's efforts to require the Company and Cocelco to
collect a monthly tax on cellular subscribers whose calls use base stations
located in Medellin. As of May 17, 1996, the amount in dispute for the period
through March 30, 1996 was Ps 565 million (US$587,236), including interest
accrued thereon. While the Company believes it will prevail in this litigation,
if it does not the Company believes that it would be able to collect from its
subscribers a portion of this tax. To the extent the Company is unsuccessful in
its attempts to collect such tax from its subscribers, it will pay such amount
to the tax authorities of Medellin. Although no other city has proposed to
implement a similar tax, there is no assurance that other cities will not do so.
An adverse outcome in the legal proceedings and the imposition of a similar tax
in other cities could have an adverse effect on the Company's financial
condition and may adversely affect its ability to meet its obligations under the
Notes. See "Business -- Legal Proceedings -- Medellin's Cellular Services Tax".
 
LIMITATIONS ON CHANGE OF CONTROL
 
     The Indenture requires the Company, in the event of a Change of Control, to
make an offer to purchase the Notes at 101% of the Accreted Value thereof, plus
accrued interest, if any, to the purchase date. Certain events involving a
Change of Control may be an event of default under the Bank Facility or
indebtedness of the Company that may be incurred in the future. Moreover, the
exercise by the holders of the Notes of their right to require the Company to
purchase the Notes may cause a default under the Bank Facility or such other
indebtedness, even if the Change of Control does not. Finally, there can be no
assurance that the Company will have the financial resources necessary to
repurchase the Notes upon a Change of Control. See "Description of the
Notes -- Certain Covenants -- Change of Control".
 
ORIGINAL ISSUE DISCOUNT
 
     Both the Old Notes and the New Notes will be treated as having been issued
at a substantial discount from their principal amount at maturity. Consequently,
United States Holders of the Notes generally will be required to include amounts
in gross income for United States federal income tax purposes in advance of
receipt of the cash payments to which such income is attributable. See
"Taxation -- United States -- Notes -- Original Issue Discount" for a more
detailed discussion of the United States federal income tax consequences to
United States Holders of the purchase, ownership and disposition of the Notes.

LACK OF ESTABLISHED MARKET FOR THE NOTES
 
     The New Notes are new securities for which there currently is no trading
market. The Company does not intend to apply for listing of the New Notes on any
national securities exchange or to seek admission thereof to trading on the
National Association of Securities Dealers Automated Quotation System. Although
the Initial Purchasers have informed the Company that they currently intend to
make a market in the New Notes, they are not obligated to do so, and any such
market-making may be discontinued at any time without notice. The liquidity of
any market for the New Notes will depend upon the number of holders of the New
Notes, the interest of securities dealers in making a market in the New Notes
and other factors. Accordingly, there can be no assurance as to the development
or liquidity of any trading market for the New Notes. The Old Notes are eligible
for trading in the PORTAL market. To the extent that Old Notes are tendered and
accepted in connection with the Exchange Offer, any trading market for remaining
Old Notes will be adversely affected.
 
     Historically, the market for non-investment grade debt has been subject to
disruptions that have caused substantial volatility in the prices of securities
similar to the Notes. There can be no assurance that the market, if any, for the
Notes will not be subject to similar disruptions. Any such disruptions may have
an adverse effect on the holders of the Notes. In addition, Colombia is
generally considered by international investors to be an "emerging market".
Political, economic, social and other developments in other "emerging markets"
may have an adverse effect on the market value and liquidity of the Notes.

                                USE OF PROCEEDS
 
     The Company will not receive any cash proceeds from the Exchange Offer.
 
                                THE REFINANCING
 
     The Old Notes were issued on June 7, 1996 pursuant to the Offering of the
Units, each of which consisted of US$1,000 principal amount at maturity of Old
Notes and the Warrants. The Old Notes and the Warrants will become separately
transferable as of the date of this Prospectus.
 
     Concurrently with the issuance of the Units, the Company borrowed US$80.0
million under the Bank Facility, which loans are secured by security interests
in, among other things, (i) all receivables originated from the provision of
cellular communications and roaming and interconnection services, (ii) the
pledge of 99.99% of the Company's outstanding stock, and (iii) the Concession.
The aggregate net proceeds of the Offering and the borrowings under the Bank
Facility were US$171.5 million. Such net proceeds were used to repay
substantially all existing indebtedness of the Company and for working capital.
See "Description of Company Indebtedness -- Bank Facility".

                               THE EXCHANGE OFFER
 
GENERAL
 
     The Company hereby offers upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal (which
together constitute the "Exchange Offer"), to exchange up to US$190,745,000
aggregate principal amount at maturity of New Notes for a like aggregate
principal amount at maturity of Old Notes properly tendered on or prior to the
Expiration Date and not withdrawn as permitted pursuant to the procedures
described below. The Exchange Offer is being made with respect to all of the Old
Notes; the total aggregate principal amount at maturity of Old Notes and New
Notes will in no event exceed US$190,745,000, except as provided in the
Indenture.
 
     As of the date of this Prospectus, US$190,745,000 aggregate principal
amount at maturity of the Old Notes was outstanding. This Prospectus, together
with the Letter of Transmittal, is first being sent on or about [          ],
1996, to all holders of Old Notes known to the Company. The Company's obligation
to accept Old Notes for exchange pursuant to the Exchange Offer is subject to
certain conditions set forth under "-- Certain Conditions to the Exchange Offer"
below and to the terms and provisions of the Registration Rights Agreement.
 
PURPOSE OF THE EXCHANGE OFFER
 
     The Old Notes were issued by the Company on June 7, 1996 in transactions
exempt from the registration requirements of the Securities Act. Accordingly,
the Old Notes may not be reoffered, resold, or otherwise transferred in the
United States unless so registered or unless an applicable exception from the
registration and prospectus delivery requirements of the Securities Act is
available.
 
     In connection with the issuance and sale of the Old Notes, the Company
entered into an Exchange and Registration Rights Agreement, dated as of June 7,
1996, (the "Registration Rights Agreement"), which requires the Company to use
its best efforts to file with the SEC a registration statement relating to the
Exchange Offer within 60 days after the Issue Date, and to use its best efforts
to cause the registration relating to the Exchange Offer to become effective
under the Securities Act within 150 days after the Issue Date and the Exchange
Offer to be consummated within 180 days after the Issue Date. The Exchange Offer
is being made by the Company to satisfy its obligations with respect to the
Registration Rights Agreement.
 
EXPIRATION DATE; EXTENSION; TERMINATION; AMENDMENT
 
     The Exchange Offer will expire at 5:00 p.m., New York City time, on [30
days after mailing of notice], 1996, unless the Company, in its sole discretion,
has extended the period of time for which the Exchange Offer is open (such date,
as it may be extended, is referred to herein as the "Expiration Date"). The
Company expressly reserves the right, at any time or from time to time, to
extend the period of time during which the Exchange Offer is open, and thereby
delay acceptance for exchange of any Old Notes, by giving oral notice (promptly
confirmed in writing) or written notice to the Exchange Agent and by giving
written notice of such extension to the holders thereof or by timely public
announcement communicated, unless otherwise required by applicable law or
regulation, by making a release through the Dow Jones News Service, in each
case, no later than 9:00 a.m. New York City time, on the next business day after
the previously scheduled Expiration Date. During any such extension, all Old
Notes previously tendered will remain subject to the Exchange Offer unless
properly withdrawn.
 
     In addition, the Company expressly reserves the right to terminate or to
amend the Exchange Offer, and not to accept for exchange any Old Notes not
theretofore accepted for exchange, upon the occurrence of any of the events
specified below under "-- Certain Conditions to the Exchange Offer". If any such
termination or amendment occurs, the Company will notify the Exchange Agent and
will either issue a press release or give oral or written notice to the holders
of the Old Notes as promptly as practicable in the manner set forth above with
respect to an extension of the Expiration Date.
 
                                       27
<PAGE>   32
 
     For purposes of the Exchange Offer, a "business day" means any day other
than a Saturday, a Sunday or a date on which banking institutions in New York
City are not required to be open, and consists of the time period from 12:01
a.m. through 12:00 midnight, New York City time.
 
PROCEDURES FOR TENDERING OLD NOTES
 
     The tender to the Company of Old Notes by a holder thereof as set forth
below and the acceptance thereof by the Company will constitute a binding
agreement between the tendering holder and the Company upon the terms and
subject to the conditions set forth in this Prospectus and in the accompanying
Letter of Transmittal.
 
     Except as set forth below, a holder of Old Notes who wishes to tender Old
Notes for exchange pursuant to the Exchange Offer must transmit a properly
completed and duly executed Letter of Transmittal, including all other documents
required by such Letter of Transmittal to the Exchange Agent at one of the
addresses set forth below under "Exchange Agent" on or prior to the Expiration
Date. In addition, either (i) certificates for such Old Notes must be received
by the Exchange Agent along with the Letter of Transmittal, or (ii) a timely
confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such Old
Notes, if such procedure is available, into the Exchange Agent's account at The
Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the
procedure for book-entry transfer described below, must be received by the
Exchange Agent prior to the Expiration Date, or (iii) the holder of Old Notes
must comply with the guaranteed delivery procedures described below.
 
     THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH DELIVERY
IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL PROPERLY INSURED, WITH RETURN
RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
INSURE TIMELY DELIVERY. NO OLD NOTES OR LETTERS OF TRANSMITTAL SHOULD BE SENT TO
THE COMPANY.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless the Old Notes surrendered for exchange
pursuant thereto are tendered (i) by a registered holder of the Old Notes who
has not completed the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" on the Letter of Transmittal or (ii) for the account of
an Eligible Institution (as defined below). In the event that signatures on a
Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantees must be by a firm which is a member
of a registered national securities exchange or a member of the National
Association of Securities Dealers, Inc. or by a clearing agency, an insured
credit union, a savings association or a commercial bank or trust company having
an office or a correspondent in the United States (collectively, "Eligible
Institutions"). If Old Notes are registered in the name of a person other than a
signer of the Letter of Transmittal, the Old Notes surrendered for exchange must
be endorsed by, or be accompanied by a written instrument or instruments of
transfer or exchange, in satisfactory form as determined by the Company in its
sole discretion, duly executed by the registered holder thereof with the
signature thereon guaranteed by an Eligible Institution.
 
     A tender will be deemed to have been received as of the date when the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by (i) the Old Notes (or a confirmation of book-entry transfer of
such Old Notes into the Exchange Agent's account at the Book-Entry Transfer
Facility) is received by the Exchange Agent, or (ii) a Notice of Guaranteed
Delivery or letter, telegram or facsimile transmission to similar effect (as
provided above) from an Eligible Institution is received by the Exchange Agent.
Issuances of New Notes in exchange for Old Notes tendered pursuant to a Notice
of Guaranteed Delivery or letter, telegram or facsimile transmission to similar
effect (as provided above) by an Eligible Institution will be made only against
timely deposit of the Letter of Transmittal (and any other required documents)
and the tendered Old Notes.
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the Company in its sole discretion, which determination shall be final and
binding. The Company reserves the absolute right to reject any and all tenders
of any particular Old Notes not properly tendered or to not accept any
particular Old Notes which acceptance might, in the judgment of the Company or
its counsel, be unlawful. The Company also reserves the absolute right to waive
 
                                       28
<PAGE>   33
 
any defects or irregularities or conditions of the Exchange Offer as to any
particular Old Notes either before or after the Expiration Date (including the
right to waive the ineligibility of any holder who seeks to tender Old Notes in
the Exchange Offer). The interpretation of the terms and conditions of the
Exchange Offer as to any particular Old Notes either before or after the
Expiration Date (including the Letter of Transmittal and the instructions
thereto) by the Company shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
for exchange must be cured within such reasonable period of time as the Company
shall determine. Neither the Company, the Exchange Agent nor any other person
shall be under any duty to give notification of any defect or irregularity with
respect to any tender of Old Notes for exchange, nor shall any of them incur any
liability for failure to give such notification.
 
     If the Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Old Notes, such Old Notes must be endorsed
or accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered holder or holders appear on the Old
Notes.
 
     If the Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted.
 
     By tendering, each holder will represent to the Company that, among other
things, the New Notes acquired pursuant to the Exchange Offer are being acquired
in the ordinary course of business of the person receiving such New Notes,
whether or not such person is the holder, that neither the holder nor any such
other person has an arrangement or understanding with any person to participate
in the distribution of such New Notes and that neither the holder nor any such
other person is an "affiliate" as defined under Rule 405 of the Securities Act,
of the Company, or if it is an affiliate it will comply with the registration
and prospectus requirements of the Securities Act to the extent applicable.
 
     Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities must acknowledge
that it will deliver a prospectus in connection with any resale of such New
Notes. See "Plan of Distribution".
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request within two business days after the
date of this Prospectus to establish accounts with respect to the Old Notes at
the Book-Entry Transfer Facility. The Depository Trust Company, for the purpose
of facilitating the Exchange Offer, and subject to the establishment thereof,
any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Old Notes by causing the
Book-Entry Transfer Facility to transfer such Old Notes into the Exchange
Agent's account with respect to the Old Notes in accordance with the Book-Entry
Transfer Facility's procedures for such transfer. Although delivery of Old Notes
may be effected through book-entry transfer into the Exchange Agent's account at
the Book-Entry Transfer Facility, an appropriate Letter of Transmittal with any
required signature guarantee and all other required documents must in each case
be transmitted to and received or confirmed by the Exchange Agent at its address
set forth below on or prior to the Expiration Date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under such procedures.
 
GUARANTEED DELIVERY PROCEDURES
 
     If a holder of Old Notes desires to accept the Exchange Offer and time will
not permit a Letter of Transmittal or Old Notes to reach the Exchange Agent
before the Expiration Date or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if the Exchange Agent has
received at its address set forth below on or prior to the Expiration Date, a
letter, telegram or facsimile transmission from an Eligible Institution setting
forth the name and address of the tendering holder, the names in which the Old
Notes are registered and, if possible, the certificate numbers of the Old Notes
to be tendered, and stating that the tender is being made thereby and
guaranteeing that within three business days after the
 
                                       29
<PAGE>   34
 
Expiration Date, the certificates for all physically tendered Old Notes, in
proper form for transfer, or a Book-Entry Confirmation of such Old Notes into
the Exchange Agent's account at the Book-Entry Transfer Facility, will be
delivered by such Eligible Institution together with a properly completed and
duly executed Letter of Transmittal (and any other required documents). Unless
Old Notes being tendered by the above-described method are deposited with the
Exchange Agent within the time period set forth above (accompanied or preceded
by a properly completed Letter of Transmittal and any other required documents),
the Company may, at its option, reject the tender. Copies of Notice of
Guaranteed Delivery which may be used by Eligible Institutions for the purposes
described in this paragraph are available from the Exchange Agent.
 
WITHDRAWAL RIGHTS
 
     Tenders of Old Notes may be withdrawn at any time prior to the Expiration
Date.
 
     For a withdrawal to be effective, a written notice of withdrawal sent by
telegram, facsimile transmission (receipt confirmed by telephone) or letter must
be received by the Exchange Agent prior to the Expiration Date at its address
set forth below. Any such notice of withdrawal must specify the name of the
person having tendered the Old Notes to be withdrawn, identify the Old Notes to
be withdrawn (including the amount of such Old Notes), and (where certificates
for Old Notes have been transmitted) specify the name in which such Old Notes
are registered, if different from that of the withdrawing holder thereof. If
certificates for Old Notes have been delivered or otherwise identified to the
Exchange Agent, then, prior to the release of such certificates the withdrawing
holder thereof must also submit the serial numbers of the particular
certificates to be withdrawn and a signed notice of withdrawal with signatures
guaranteed by an Eligible Institution unless such holder is an Eligible
Institution. If Old Notes have been tendered pursuant to the procedure for book-
entry transfer described above, any notice of withdrawal must specify the name
and number of the account at the Book-Entry Transfer Facility to be credited
with the withdrawn Old Notes and otherwise comply with the procedures of such
facility. All questions as to the validity, form and eligibility (including time
of receipt) of such notices will be determined by the Company in its sole
discretion, which determination will be final and binding on all parties. Any
Old Notes so withdrawn will be deemed not to have been validly tendered for
exchange for purposes of the Exchange Offer. Any Old Notes which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the holder thereof without cost to such holder (or, in the case of
Old Notes tendered by book-entry transfer into the Exchange Agent's account at
the Book-Entry Transfer Facility pursuant to the book-entry transfer procedures
described above, such Old Notes will be credited to an account with such
Book-Entry Transfer Facility specified by the holder thereof) as soon as
practicable after such withdrawal, rejection of tender or termination of the
Exchange Offer. Properly withdrawn Old Notes may be retendered by following one
of the procedures described under "-- Procedures for Tendering Old Notes" above
at any time on or prior to the Expiration Date.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company will accept, promptly after the Expiration Date, all Old Notes
properly tendered prior to 5:00 p.m., New York City time, on the Expiration Date
and will issue the New Notes promptly after such acceptance. See "-- Certain
Conditions to the Exchange Offer" below. For purposes of the Exchange Offer, the
Company shall be deemed to have accepted properly tendered Old Notes for
exchange when, as and if the Company has given oral and written notice thereof
to the Exchange Agent, with written confirmation of any oral notice to be given
promptly thereafter.
 
     For each Old Note accepted for exchange, the holder of such Old Note will
receive a New Note having a principal amount equal to that of the surrendered
Old Note.
 
     In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely Book-Entry
Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal and all other required documents. If any tendered Old Notes are not
accepted for any reason set forth in the terms and
 
                                       30
<PAGE>   35
 
conditions of the Exchange Offer or if Old Notes are submitted for a greater
principal amount than the holder desires to exchange, such unaccepted or
non-exchanged Old Notes will be returned without expense to the tendering holder
thereof (or, in the case of Old Notes tendered by book-entry transfer into the
Exchange Agent's account at the Book-Entry Transfer Facility pursuant to the
book-entry transfer procedures described below, such non-exchanged Old Notes
will be credited to an account maintained with such Book-Entry Transfer
Facility) as promptly as practicable after the expiration of the Exchange Offer.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other provision of the Exchange Offer, the Company
shall not be required to accept for exchange, or to issue New Notes in exchange
for, any Old Notes and may terminate or amend the Exchange Offer if at any time
before the acceptance of such Old Notes for exchange or the exchange of the New
Notes for such Old Notes, any of the following events shall occur:
 
          (i) there shall be threatened, instituted or pending any action or
     proceeding before, or any injunction, order or decree shall have been
     issued by, any court or any governmental agency seeking to restrain or
     prohibit or prevent the Company from proceeding with the Exchange Offer or
     assessing or seeking any damages as a result thereof, or that might result
     in a material adverse effect on the contemplated benefits of the Exchange
     Offer to the Company; or
 
          (ii) there shall be proposed, enacted, promulgated or deemed
     applicable to the Exchange Offer by any government or governmental agency
     or authority any law or regulation, including any applicable interpretation
     of the staff of the SEC, that might in the sole judgment of the Company
     result in any of the consequences described in clause (i).
 
     The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any such
condition or may be waived by the Company in whole or in part at any time and
from time to time in its reasonable judgment. The failure by the Company at any
time to exercise any of the foregoing rights shall not be deemed a waiver of any
such right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.
 
     In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes, if
at such time any stop order shall be threatened or in effect with respect to the
Registration Statement of which this Prospectus constitutes a part or the
qualification of the Indenture under the Trust Indenture Act of 1939 (the
"TIA"). In any such event the Company is required to use every reasonable effort
to obtain the withdrawal of any stop order at the earliest possible time.
 
     The Exchange Offer is not conditioned upon any minimum principal amount of
Old Notes being tendered for exchange.
 
EXCHANGE AGENT
 
     The Bank of New York has been appointed as the Exchange Agent for the
Exchange Offer. All tendered Old Notes, executed Letters of Transmittal, and
other related documents should be directed to the Exchange Agent at one of the
addresses set forth in the Letter of Transmittal. Questions and requests for
assistance, requests for additional copies of this Prospectus or of the Letter
of Transmittal and requests for Notices of Guaranteed Delivery should be
directed to the Exchange Agent at the address set forth in the Letter of
Transmittal.
 
     The Bank of New York also acts as Trustee under the Indenture.
 
SOLICITATION OF TENDERS; FEES AND EXPENSES
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith. The
Company will also pay brokerage houses
 
                                       31
<PAGE>   36
 
and other custodians, nominees and fiduciaries the reasonable out-of-pocket
expenses incurred by them in forwarding copies of this and other related
documents to the beneficial owners of the Old Notes and in handling or
forwarding tenders for their customers.
 
     The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Company and are estimated in the aggregate to be
approximately $[          ], which includes fees and expenses of the Exchange
Agent, Trustee, registration fees, accounting, legal, printing and related fees
and expenses.
 
     No person has been authorized to give any information or to make any
representations in connection with the Exchange Offer other than those contained
in this Prospectus. If given or made, such information or representations should
not be relied upon as having been authorized by the Company. Neither the
delivery of this Prospectus nor any exchange made hereunder shall, under any
circumstances, create any implication that there has been no change in the
affairs of the Company since the respective dates as of which information is
given herein. The Exchange Offer is not being made to (nor will tenders be
accepted from or on behalf of) holders of Old Notes in any jurisdiction in which
the making of the Exchange Offer or the acceptance thereof would not be in
compliance with the laws of such jurisdiction.
 
TRANSFER TAXES
 
     Holders who tender their Old Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith except that holders who instruct
the Company to register New Notes in the name of, or request Old Notes not
tendered or not accepted in the Exchange Offer be returned to, a person other
than the registered tendering holder will be responsible for the payment of any
applicable transfer tax thereon.
 
ACCRETED VALUE OF THE NEW NOTES
 
     No cash interest is payable on the Notes prior to March 15, 2001. Thus,
holders of Old Notes that are accepted for exchange will not receive accrued
interest thereon at the time of exchange. The Accreted Value of the New Notes
initially will be equal to the Accreted Value of the Old Notes at the time of
the exchange. See "Description of the Notes -- Certain Definitions" for the
definition of "Accreted Value".
 
ACCOUNTING TREATMENT
 
     The New Notes will be recorded at the carrying value of the Old Notes as
reflected in the Company's accounting records on the date of the exchange.
Accordingly, no gain or loss for accounting purposes will be recognized by the
Company upon the exchange of New Notes for Old Notes. Expenses incurred in
connection with the issuance of the New Notes will be amortized over the term of
the New Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE; RESALE OF NEW NOTES
 
     Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon as a
consequence of the issuance of the Old Notes pursuant to the exemptions from, or
in transactions not subject to, the registration requirements of the Securities
Act and applicable state securities laws. Old Notes not exchanged pursuant to
the Exchange Offer will continue to remain outstanding in accordance with their
terms. In general, the Old Notes may not be offered or sold unless registered
under the Securities Act, except pursuant to an exemption from, or in a
transaction not subject to, the Securities Act and applicable state securities
laws. The Company does not currently anticipate that it will register the Old
Notes under the Securities Act. However, (i) if the Initial Purchaser so
requests with respect to Old Notes not eligible to be exchanged for New Notes in
the Exchange Offer and held by it following consummation of the Exchange Offer
or (ii) if any holder of Old Notes is not eligible to participate in the
Exchange Offer or, in the case of any holder of Old Notes that participates in
the Exchange Offer, does not receive freely tradeable New Notes in exchange for
Old Notes, the Company is obligated to file a registration statement on the
appropriate form under the Securities Act relating to the Old Notes held by such
persons.
 
                                       32

     Based on certain no-action letters issued by the staff of the SEC to third
parties in unrelated transactions, the Company believes that New Notes issued
pursuant to the Exchange Offer may be offered for resale, resold or otherwise
transferred by holders thereof (other than (i) any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act or (ii) any broker-dealer that purchases Notes from the Company to resell
pursuant to Rule 144A or any other available exemption) without compliance with
the registration and prospectus delivery provisions of the Securities Act,
provided that such New Notes are acquired in the ordinary course of such
holders' business and such holders have no arrangement or understanding with any
person to participate in the distribution of such New Notes. If any holder has
any arrangement or understanding with respect to the distribution of the New
Notes to be acquired pursuant to the Exchange Offer, such holder (i) could not
rely on the applicable interpretations of the staff of the SEC and (ii) must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction. Thus, any New
Notes acquired by such holder will not be freely transferable except in
compliance with the Securities Act. A broker-dealer who holds Old Notes that
were acquired for its own account as a result of market-making or other trading
activities may be deemed to be an "underwriter" within the meaning of the
Securities Act and must, therefore, deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of New Notes.
Each such broker-dealer that receives New Notes for its own account in exchange
for Old Notes, where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
in the Letter of Transmittal that it will deliver a prospectus in connection
with any resale of such New Notes. See "Plan of Distribution".
 
     In addition, to comply with the securities laws of certain jurisdictions,
if applicable, the New Notes may not be offered or sold unless they have been
registered or qualified for sale in such jurisdiction or an exemption from
registration or qualification is available and is complied with. The Company has
agreed, pursuant to the Registration Rights Agreement and subject to certain
specific limitations therein, to register or qualify the New Notes for offer or
sale under the securities or blue sky laws of such jurisdictions as any holder
of the Notes reasonably requests in writing.
 
     Participation in the Exchange Offer is voluntary, and holders of Old Notes
should carefully consider whether to participate. Holders of the Old Notes are
urged to consult their financial and tax advisors in making their own decision
on what action to take.
 
     As a result of the making of, and upon acceptance for exchange of all
validly tendered Old Notes pursuant to the terms of this Exchange Offer, the
Company will have fulfilled a covenant contained in the Registration Rights
Agreement. Holders of Old Notes who do not tender their Old Notes in the
Exchange Offer will continue to hold such Old Notes and will be entitled to all
the rights, and limitations applicable thereto, under the Indenture, except for
any such rights under the Registration Rights Agreement that by their terms
terminate or cease to have further effectiveness as a result of the making of
this Exchange Offer. See "Description of Notes". All untendered Old Notes will
continue to be subject to the restrictions on transfer set forth in the
Indenture. To the extent that Old Notes are tendered and accepted in the
Exchange Offer, the trading market for untendered Old Notes could be adversely
affected.
 
     The Company may in the future seek to acquire untendered Old Notes in open
market or privately negotiated transactions, through subsequent exchange offers
or otherwise. The Company has no present plan to acquire any Old Notes which are
not tendered in the Exchange Offer.

                     SELECTED FINANCIAL AND OPERATING DATA
 
     The selected statement of operations data for each of the fiscal years
ended December 31, 1993, 1994 and 1995, and the balance sheet data dated as of
December 31, 1994 and 1995 are derived from the Company's financial statements
which have been audited by KPMG Peat Marwick, independent auditors. The
historical information for the three months ended March 31, 1995 and 1996 has
been derived from the unaudited financial statements of the Company included
herein. In the opinion of management, the information for the three month
periods ended March 31, 1995 and 1996 includes all material adjustments
(consisting only of adjustments of a normal and recurring nature) necessary for
a fair presentation of the results for such periods. The results of operations
for any interim period are not necessarily indicative of the results of
operations for a full year. This information should be read in conjunction with,
and is qualified in its entirety by reference to, such financial statements,
including the notes thereto, which are included elsewhere in this Prospectus.
 
     The Company was organized in February 1992 to participate in the auctioning
of cellular concessions by the Colombian government. The Company commenced
commercial cellular telephone service operations in September 1994. Accordingly,
the Company had no commercial operating history prior to such time, and results
for 1994 are not directly comparable to those of 1995.
 
     The financial statements included in this Prospectus have been prepared in
conformity with generally accepted accounting principles in Colombia ("Colombian
GAAP"), which differ in certain significant respects from generally accepted
accounting principles in the United States ("U.S. GAAP"). Note 17 to the
financial statements provides a description of the principal differences between
Colombian GAAP and U.S. GAAP as they relate to the Company, as well as a
reconciliation of the Company's net income (loss) and shareholders' equity
calculated in accordance with Colombian GAAP to amounts calculated in accordance
with U.S. GAAP.
 
     In accordance with the requirements of the SEC, the selected financial
information included herein and in the accompanying financial statements and
notes thereto for all periods presented has been restated into constant Pesos as
of the latest balance sheet date (March 31, 1996), using the Colombian consumer
price index, in order to express all financial information in purchasing power
as of the date of the latest balance sheet. Because of such requirements, the
Company's historical financial information will be revised from time to time in
the future when it publishes a new balance sheet so that such information is
restated in constant Pesos as of such latest date.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
 
     The following is a discussion of the financial condition and results of
operations of the Company as of and for the fiscal years ended December 31, 1995
and December 31, 1994 and the three-month periods ended March 31, 1996 and March
31, 1995. The discussion should be read in conjunction with the financial
statements of the Company and the notes thereto included elsewhere in this
Prospectus. The financial statements have been prepared in accordance with
Colombian GAAP, which differs in certain significant respects from US GAAP. Note
17 to the Company's financial statements provides a description of the
differences between US GAAP and Colombian GAAP, as well as a reconciliation to
US GAAP of the Company's net income (loss) and shareholders' equity. In
accordance with the requirements of the SEC, unless otherwise indicated, the
financial information has been presented in constant Pesos as of the latest
balance sheet date (March 31, 1996) in order to express all financial
information in purchasing power as of such date. See note 1 to the Company's
financial statements for a description of such constant Peso adjustments. The
following discussion gives all amounts in Pesos as well as in U.S. dollars. Such
U.S. dollar amounts are convenience translations of the Peso amounts at the
Representative Market Rate for March 31, 1996, which was 1,046.00 Pesos to one
U.S. dollar.
 
GENERAL
 
     The Company was awarded the Concession in March 1994 and began its
commercial service in September of the same year. Therefore, the balance sheet
and income statement as of and for the year ended December 31, 1994, reflect the
fact that the Company was in a pre-operative, development stage during the first
eight months of 1994 and was in commercial operation during the last four months
of such year. In light of the foregoing, the financial information for 1994 is
not directly comparable to that for 1995.
 
     On April 13, 1994, the Company paid Ps 123.1 billion (actual Pesos)
(US$148.5 million at the April 13, 1994 Representative Market Rate) to the
government for the Concession. This amount is being amortized over nine years
and seven months beginning September 1994, which period is the remaining term of
the Concession as of such date, using the units of activation method. To
calculate the monthly amortization charge, this method utilizes the sum of the
projected subscribers per month for each month during the term of the Concession
as the denominator and the sum of the subscribers per month for each month in
the reporting period as the numerator. The Company will revise the underlying
projections of subscribers on a periodic basis, and any resulting impact on
amortization expense will be accounted for in subsequent periods. The Company is
also obligated to pay the government a quarterly royalty payment during the term
of the Concession equal to 5% of the sum of activation fees, monthly fixed fees,
airtime charges, interconnection fees and supplementary services, minus
interconnection costs paid by the Company to other telecommunications operators.
Such royalty payment is included in operating costs in the Company's financial
statements.
 
     The Company generates revenue from (i) activation fees, which are the
initial charges paid by a new subscriber for service, (ii) monthly fixed fees,
which vary depending on the tariff plan chosen by the subscriber, (iii) airtime
charges, which are billed based on usage, vary depending upon the tariff plan
chosen and, under Colombia's calling party pays system, include airtime charges
received from other cellular and wireline operators for calls routed to the
Company's network, (iv) revenues from the sale of equipment to subscribers,
consisting of handsets and accessories and (v) other revenues generated from
roaming, domestic long-distance and value-added and supplementary services.
Equipment sales are made directly by the Company to its customers or to its
independent distributors. The Company believes its roaming, long-distance and
value-added and supplementary services are an important element in attracting
customers, although such services have not been a significant component of total
revenue thus far.
 
     The Company has varied the pricing of all the components of its services in
accordance with its marketing plan and in light of competitive factors, and
expects to continue to do so in the future. In particular, the Company
introduced a short-term pricing initiative in the first quarter of 1995 during a
period of price competition with its principal competitor, Cocelco, pursuant to
which it significantly reduced prices in order to capture market share as
discussed below. Following such period, the Company's airtime and monthly fixed
fees have returned to levels approximating those in effect at the end of 1994,
although the Company has kept
 
                                       37
<PAGE>   42
 
its activation fees low in order to attract subscribers. In December 1995, the
Company began a promotional campaign pursuant to which it does not charge any
activation fee.
 
     Consistent with cellular start-up environments, the Company believes that
the current fees and airtime tariffs charged by Colombian operators, including
the Company, are generally higher than those charged in more mature cellular
markets outside of Colombia. Accordingly, the Company believes that as the
market for cellular services in Colombia matures, prices will generally fall,
but at the same time the number of subscribers in Colombia should increase.
 
     The term "reported subscribers" means subscribers as reported by the
Company to the Colombian Ministry of Communications. Prior to September 1995, in
accordance with the reporting guidelines of the Ministry of Communications, the
Company filed quarterly reports which did not cover calendar quarters, but
lagged by approximately one month. For purposes of consistency, reported
subscribers set forth herein for periods prior to September 1995 have been
calculated to conform to calendar quarters. Consistent with the Company's
interpretation of the Ministry's reporting guidelines and with what the Company
believes to be the common interpretation of cellular operators in Colombia, the
Company includes in such term subscribers who have been temporarily
disconnected, and are under evaluation by the Company for reconnection or
permanent deactivation. Prior to September 1995, "reported subscribers" also
included permanently deactivated customers. See also the discussion under
"-- Price Competition and Related Matters" in the comparison of 1995 to 1994.
 
     Active subscribers is the Company's internal measure of subscribers
currently generating revenue, and thus is equal to reported subscribers less all
disconnected subscribers. Calculations of revenue per subscriber, monthly fees
per subscriber and usage per subscriber are made on the basis of active
subscribers. Activation fees per new subscriber and equipment sales per new
subscriber for a period are calculated based on the incremental increase in
reported subscribers for such period.
 
     See the discussion under "Price Competition and Related Matters" in the
comparison of 1995 to 1994 for a discussion of the differences between total
reported and active subscribers.
 
     Cellular operators typically experience losses and negative cash flow in
their initial years of operation due to the large capital investments required
for construction of their networks and the significant advertising and other
expenses needed to start the business. Consistent with this pattern, the Company
has incurred cumulative losses and negative cash flow from operations since
inception. The Company reported net losses for the years ended December 31, 1994
and, December 31, 1995 and the quarter ended March 31, 1996 of Ps 3.1 billion
(US$3.0 million), Ps 43.8 billion (US$41. 8 million) and Ps 5.2 billion (US$ 4.9
million), respectively. In addition, the purchase price for the Concession has
been capitalized and is being amortized over its term as described above.
 
     Effective January 1, 1996, according to Law 223/1995, the Company is liable
for income tax at a statutory tax rate of 35%. Before this change in the law,
the Company was not liable for income tax and, therefore, no provision was
recorded for income taxes. Fiscal losses may be carried forward for tax purposes
for five years. In 1996 and future years, the Company's tax liability will be
calculated based on the greater of (i) net taxable income and (ii) presumed
income, which is the greater of 5% of shareholders' fiscal equity and 1.5% of
total assets, in each case at the end of the previous fiscal year.
 
ACCOUNTING FOR INFLATION
 
     As a Colombian company, the Company maintains its financial records in
Colombian pesos. Effective January 1, 1992, Colombian GAAP required that the
financial statements of Colombian companies be adjusted to account for
inflation. Financial statements are adjusted for the effects of inflation on the
basis of changes in the Colombian CPI. This index is applied, on a one-month
lagging basis, to non-monetary assets and liabilities, shareholders' equity,
revenues and expense accounts. Monetary balances are not adjusted because they
reflect the purchasing power of the currency at the date of the balance sheet.
Foreign currency balances are not adjusted because they are translated into
Pesos at the exchange rate in effect on the date of the balance sheet and
consequently reflect the purchasing power of the currency on that date. The
resulting
 
                                       38
<PAGE>   43
 
net gain or loss from exposure to inflation is reflected as "Net monetary
correction" in the income statement for the period in question. See notes 1 and
15 to the Company's financial statements.
 
RESULTS OF OPERATION
 
YEAR ENDED DECEMBER 31, 1994 (FOUR MONTHS OF COMMERCIAL OPERATIONS)
 
     For the period from January 1, 1994 through August 31, 1994, the Company
was in a pre-operating phase. Accordingly, the Company did not generate any
revenues (although it had income from investments of excess cash), and
substantially all expenses during this period were capitalized in accordance
with Colombian GAAP. Such preoperating capitalized expenses consisted primarily
of expenses related to the construction of the Company's cellular network as
well as the development of the Company's corporate infrastructure. Such amount,
which is amortized as discussed below, totalled Ps 14.8 billion (US$14.1
million).
 
     Except as noted below, all references to 1994 mean the four months of
commercial operation.
 
  Revenues
 
     Revenues during 1994 were Ps 10.0 billion (US$9.6 million), all of which
were realized during the last four months of the year. Of such total, Ps 4.4
billion (US$4.2 million), or 44%, came from activation fees from new
subscribers, and Ps 3.6 billion (US$3.4 million), or 36%, came from sales of
equipment. The remainder came from airtime charges (8%) and monthly fixed fees
(12%).
 
     As of December 31, 1994, the Company had 9,356 reported subscribers.
Average monthly revenue per subscriber for 1994 was Ps 120,777 (US$115).
 
     Average activation charges per new subscriber in 1994 were Ps 465,781
(US$445). As is typical for cellular operators in the start-up period, this rate
was significantly higher than the rates the Company expects to realize in future
periods. Equipment sales were also made at average prices higher than those the
Company expects to realize in the future. Average airtime per subscriber was 207
minutes. Minutes in excess of those included in the basic service were charged
at an average of Ps 265 (US$0.25) per minute. Average monthly fixed fees per
subscriber were Ps 73,879 (US$71).
 
  Costs and Expenses
 
     Costs and expenses for 1994 were Ps 14.0 billion (US$13.4 million),
substantially all of which were incurred during the last four months of the
year.
 
     Operating costs were Ps 3.9 billion (US$3.7 million), or 39% of revenue.
Such expenses consist of cost of equipment sales, interconnection fees paid to
local wireline operators (for calls routed through their networks) and the
quarterly royalty payment to the government pursuant to the Concession. Cost of
equipment sales, which were Ps 3.1 billion (US$3.0 million), represent costs of
handsets and accessories sold by the Company directly to its subscribers or to
its distributors. Interconnection charges and the royalty payment (which
totalled Ps 0.8 billion (US$0.7 million)) were low because the Company commenced
commercial operations during this period.
 
     The largest component of costs and expenses (32%) was marketing and selling
expenses, which were Ps 4.5 billion (US$4.3 million), reflecting the Company's
emphasis on marketing efforts to build awareness among potential subscribers of
its "Vozavoz" brand name, its services and its image. Such expenses consisted
principally of advertising and publicity costs as well as incentives and
commissions paid to salespeople.
 
     General and administrative expenses were Ps 4.0 billion (US$3.8 million),
or 29% of total costs and expenses.
 
     Depreciation and amortization, which totalled Ps 1.6 billion (US$1.5
million) and represented 11% of total costs and expenses, consisted of (i)
amortization of intangibles (consisting of the purchase price of the
Concession), (ii) amortization of deferred charges (principally pre-operating
expenses) and (iii) depreciation.
 
                                       39
<PAGE>   44
 
  EBITDA
 
     As a result of the foregoing, EBITDA for 1994 was a negative Ps 2.4 billion
(US$2.3 million). See note [8] under "Selected Financial and Operating Data".
 
  Operating Loss
 
     As a result of the foregoing, the Company had an operating loss of Ps 4.0
billion (US$3.8 million) for 1994.
 
  Other Income (Expense)
 
     Other income, net, was Ps 0.9 billion (US$0.9 million). This was comprised
of interest income of Ps 6.0 billion (US$5.7 million), of which 52% resulted
from investments of excess cash and 48% from foreign exchange gains and other
adjustments, and net monetary correction of Ps 2.9 billion (US$2.8 million).
Other income was offset in part primarily by interest expense on indebtedness of
Ps 5.0 billion (US$4.8 million) and foreign exchange losses on the U.S.
dollar-denominated portion of such indebtedness of $2.8 billion (US$2.7
million). Such indebtedness was used to fund capital expenditures, working
capital and other operating costs and a portion of the purchase price of the
Concession. The foreign exchange losses resulted from the devaluation of the
Peso during this period from 816.08 Pesos to one U.S. dollar as of September 1,
1994 to 831.27 Pesos to one U.S. dollar as of December 31, 1994.
 
     Substantially all of the monetary correction, which represents the
aggregate impact of inflation adjustments to non-monetary assets and
liabilities, income statement accounts and shareholders' equity, reflected
inflation adjustments to balance sheet accounts. (See also note 15 to the
financial statements of the Company.)
 
  Net Loss
 
     As a result of the foregoing, the Company incurred a net loss of Ps 3.1
billion (US$3.0 million) during 1994.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED WITH YEAR ENDED DECEMBER 31, 1994
 
     Because 1995 reflects a full year of commercial operations, it is not
directly comparable to 1994, which includes only four months of commercial
operations. References to 1994 mean such four months unless otherwise noted.
 
  Revenues
 
     Revenues for 1995 were Ps 43.0 billion (US$41.1 million), an increase of
330% over 1994 revenues of Ps 10.0 billion (US$9.6 million). Such increase
reflected the full year of operations and the significant growth in reported
subscribers, which increased from 9,356 as of December 31, 1994 to 40,887 as of
December 31, 1995.
 
     The composition of revenue changed significantly as a result of the full
year of operations and the significant growth of subscribers, as well as certain
pricing changes and the price competition discussed below. Airtime charges
represented 41% of total revenue in 1995 compared to 8% in 1994, and monthly
fixed fees were 31% of revenue in 1995 compared to 12% in 1994. Equipment sales
represented 23% of revenue in 1995 compared to 36% in 1994, and activation fees
were 3% of revenue in 1995 compared to 44% in 1994. The remaining 2% of revenues
in 1995 consisted of other revenues, principally attributable to roaming charges
for which the Company did not charge prior to 1995.
 
     Revenue in all categories except activation fees increased significantly in
1995 compared to 1994. Airtime charges were Ps 17.5 billion (US$16.7 million) in
1995, compared to Ps 0.8 billion (US$0.8 million) in 1994. This reflected the
full year of operations, the increased number of subscribers, and an increase in
average usage per subscriber. Average minutes per subscriber increased
approximately 18% from 207 minutes in 1994
 
                                       40
<PAGE>   45
 
to 244 minutes in 1995. In addition, the average billed rate per minute
increased 41% from Ps 265 (US$0.25) in 1994 to Ps 374 (US$0.36) in 1995
primarily because of the inclusion of interconnection revenues for incoming
calls. This was partially offset by a reduction in prices discussed below.
 
     Monthly fixed fees were Ps 13.3 billion (US$12.7 million) in 1995, compared
to Ps 1.2 billion (US$1.1 million) in 1994. This again reflected the full year
of operations and the increased subscriber base. The average monthly fixed fee
per subscriber was Ps 46,585 (US$45) in 1995, a 37% decrease compared to the
1994 rate of Ps 73,879 (US$71). The Company reduced its monthly fixed fees in
order to increase its subscriber base and stimulate usage.
 
     Revenue from equipment sales was Ps 9.8 billion (US$9.4 million) in 1995,
an increase of 172% over 1994, which reflected the increase in subscribers,
partially offset by certain decreases in equipment prices.
 
     Activation fees were Ps 1.3 billion (US$1.2 million), compared to Ps 4.4
billion (US$4.2 million) in 1994. This reflected the substantial drop in average
activation fees per customer from Ps 465,781 (US$445) in 1994 to Ps 40,473
(US$39) in 1995, the effect of which was offset in part by the growth in
subscribers. Such decline was in part planned as the Company sought to broaden
its subscriber base in order to increase total revenues and was in part due to
price competition discussed below.
 
  Price Competition and Related Matters
 
     Beginning in January 1995, the Company substantially reduced its subscriber
charges in all categories in order to respond to price reductions by its
principal competitor, Cocelco. The Company reduced activation fees from Ps
650,000 (US$621) as of December 31, 1994 to Ps 290,000 (US$277) as of January
31, 1995, kept monthly fixed fees for its basic service at Ps 37,000 (US$35) and
reduced airtime charges for its basic service per peak minute from Ps 370
(US$0.35) as of December 31, 1994 to Ps 250 (US$0.24) as of January 31, 1995 and
per off peak minute from Ps 190 (US$0.18) as of December 31, 1994 to Ps 125
(US$0.12) as of January 31, 1995. Subsequently, the Company charged customers a
fee of Ps 290,000 (US$277) for activation as well as equipment, which
effectively reduced activation fees to zero. The Company believes these
reductions were the primary reason for the substantial increase in reported
customers in the first quarter of 1995, from 9,356 as of December 31, 1994 to
31,080 as of March 31, 1995. The price competition abated in the second quarter
of 1995, and the Company began at the end of the second quarter to increase its
average activation price, monthly fixed fees and airtime charges. The Company
also began to promote the use of digital handsets by setting the activation
charge for digital users lower than the activation charge for analog users. As
of December 31, 1995, airtime and monthly fixed fees returned to approximate
December 31, 1994 levels; however, in December, 1995, the Company began a
promotional campaign pursuant to which it does not charge any activation fee.
The foregoing prices are in actual Pesos and are translated into Dollars at the
Representative Market Rate on March 31, 1996.
 
     In order to rapidly establish awareness of cellular services and to respond
to the price competition, the Company's top priority during this period was to
increase its subscriber base. In order to accomplish this objective, management
did not strictly enforce its policies for managing customer credit checks, late
payments and collections. As a result, the Company found that its customer
accounts receivable were increasing at a fast rate because many of the customers
who joined in the first quarter of 1995 in particular were behind in payments.
The Company believes this reflected, among other things, a lower average credit
quality among those new customers as well as the fact that many of them did not
intend to be long-term customers, especially as prices increased.
 
     Beginning in August 1995, the Company implemented a variety of measures to
deal with late payments, collections and credit standards. The Company took more
aggressive action to temporarily disconnect customers who were behind in their
payments and to evaluate the reasons for late payments. Such actions included
enforcement of gradual restrictions on a subscriber's service, temporary
disconnection generally after 45 days, and, where appropriate, permanent
disconnection after 120 days, following the billing date. The Company also
implemented more thorough credit checks on new subscribers requiring credit
approval before activating service. All these measures were designed to upgrade
the credit quality of the Company's customers, minimize churn and minimize the
risk that subscribers would accumulate large unpaid balances.
 
                                       41
<PAGE>   46
 
     Through the Company actions described above, as well as voluntary
terminations, the Company expects that a significant number of its subscribers
(including approximately half of the customers who joined in the first quarter
of 1995) will ultimately be permanently deactivated or will otherwise leave its
subscriber base, although this will only be determined over time. As a result,
approximately 12,000 of the approximately 41,000 reported subscribers as of
December 31, 1995 are not considered active subscribers. Approximately 12,500 of
the approximately 48,500 reported subscribers as of March 31, 1996 are not
considered active subscribers.
 
     The Company believes that as a result of its actions it has increased the
overall credit quality of its customers and it has the policies and systems in
place to effectively manage subscriber growth. In connection with these efforts,
the Company in late 1995 implemented a new software package for general
accounting. The Company also expects to implement by the end of the second
quarter of 1996 a new software package designed to further improve the
administration of collections.
 
  Costs and Expenses
 
     Costs and expenses were Ps 63.7 billion (US$60.9 million), an increase of
355% over Ps 14.0 billion (US$13.4 million) in 1994. Such increase reflected the
overall growth in the business and, in particular, an increase in operating
costs because of the substantial increase in the number of subscribers.
 
     Operating costs were Ps 20.9 billion (US$19.9 million), compared to the
1994 amount of Ps 3.9 billion (US$3.7 million), and represented 49% of revenue
compared to 39% in 1994, primarily reflecting the leasing of equipment,
long-distance and interconnection fees and leased lines, none of which were
incurred in 1994. Included in operating costs were cost of equipment sold of Ps
9.4 billion (US$9.0 million) in 1995, compared to Ps 3.1 billion (US$3.0
million) in 1994, and interconnection charges and the quarterly royalty payment
to the government which totalled Ps 4.4 billion (US$4.2 million) in 1995
compared to Ps 0.8 billion (US$0.7 million) in 1994.
 
     Marketing and selling expenses were Ps 11.9 billion (US$11.4 million),
compared to Ps 4.5 billion (US$4.3 million) in 1994. Such costs were 28% of
revenue in 1995 compared to 45% in 1994, reflecting the realization of economies
of scale in sales and marketing.
 
     General and administrative costs were Ps 19.0 billion (US$18.2 million),
compared to the 1994 amount of Ps 4.0 billion (US$3.8 million), reflecting the
growth of the Company. Approximately 27% of such total constituted a provision
for bad debt of Ps 5.1 billion (US$4.9 million) which was related to the actions
by the Company to upgrade the quality of its customer base discussed above.
General and administrative costs were 44% of revenue in 1995 compared to 40% in
1994, primarily because of such provision.
 
     Depreciation and amortization was Ps 12.0 billion (US$11.5 million),
compared to Ps 1.6 billion (US$1.5 million) in 1994. Such charges were 28% of
revenues in 1995 compared to 16% in 1994, primarily because the growth in
subscribers increased amortization of intangibles under the units of activation
method as discussed above, and depreciation increased because of the increase in
property, plant and equipment from Ps $41.1 billion (US$39.3 million) as of
December 31, 1994 to Ps 68.6 billion (US$65.6 million) as of December 31, 1995.
 
  EBITDA
 
     As a result of the foregoing, EBITDA for 1995 was a negative Ps 8.7 billion
(US$8.3 million), compared to a negative Ps 2.4 billion (US$2.3 million) in
1994. See note 8 under "Selected Financial and Operating Data".
 
  Operating Loss
 
     As a result of the foregoing, the Company incurred an operating loss of Ps
20.7 billion (US$19.8 million) in 1995 compared to an operating loss of Ps 4.0
billion (US$3.8 million) in 1994.

  Other Income (Expense)
 
     Other expense, net, in 1995 amounted to Ps 23.1 billion (US$22.1 million),
compared to other income, net, of Ps 0.9 billion (US$0.9 million) in 1994. Other
expense consisted of interest expense on indebtedness of Ps 26.6 billion
(US$25.4 million) in 1995 compared to Ps 5.0 billion (US$4.8 million) in 1994
and foreign exchange losses on U.S. dollar-denominated indebtedness of Ps 20.2
billion (US$19.3 million) in 1995 compared to Ps 2.8 billion (US$2.7 million) in
1994. Such increases were primarily due to the devaluation of the Peso, as well
as the effect of the full year of interest expense in 1995 as opposed to four
months in 1994. The foreign exchange losses reflected devaluation of the Peso
from 831.27 Pesos to one U.S. dollar at December 31, 1994 to 987.65 Pesos to one
U.S. dollar at December 31, 1995. Such other expenses were offset in part
primarily by interest income of Ps 2.2 billion (US$2.1 million) compared to Ps
6.0 billion (US$5.7 million) in 1994, and a net monetary correction of Ps 21.8
billion (US$20.8 million) in 1995 compared to Ps 2.9 billion (US$2.8 million) in
1994. Of the total interest income in 1995, 37% resulted from investments of
excess cash compared to 52% in 1994 and 63% resulted from foreign exchange gains
and other adjustments compared to 48% in 1994.
 
     The increase in the monetary correction resulted primarily from an increase
in the valuation of intangibles and property, plant and equipment, partially
offset by an increase in shareholders' equity in 1994. Of the total monetary
correction, 85% was attributable to balance sheet account adjustments and the
remainder to income statement account adjustments.
 
  Net Loss
 
     As a result of the foregoing, the Company had a net loss of Ps 43.8 billion
(US$41.9 million), compared to a net loss of Ps 3.1 billion (US$3.0 million) in
1994.
 
THREE MONTHS ENDED MARCH 31, 1996 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1995
 
  Revenues
 
     Revenues for the three-month period ended March 31, 1996 were Ps 17.0
billion (US$16.2 million), an increase of 127% over the revenues for the
three-month period ended March 31, 1995 of Ps 7.5 billion (US$7.2 million). Such
increase reflected the significant growth in reported subscribers, which
increased from 31,080 as of March 31, 1995 to 48,460 as of March 31, 1996.
 
     The composition of revenue changed significantly as a result of an increase
in airtime charges and a decrease in equipment sales in the first quarter of
1996 compared to the first quarter of 1995. Airtime charges increased
principally as a result of higher tariffs and an increase in the number of
subscribers. Equipment sales declined primarily due to an overall market decline
in the price of handsets and a subsidy given by the Company beginning in the
first quarter of 1996 to promote the sale of digital handsets. Airtime charges
represented 51% of total revenue in the three-month period ended March 31, 1996
compared to 15% in 1995, and monthly fixed fees were 26% of revenue in the
three-month period ended March 31, 1996 compared to 23% in the three-month
period ended March 31, 1995. Equipment sales represented 12% of revenue in the
three-month period ended March 31, 1996 compared to 54% in the three-month
period ended March 31, 1995, and activation fees were 1% of revenue in the
three-month period ended March 31, 1996 compared to 8% in the three-month period
ended March 31, 1995. The remaining 11% of revenues in the three-month period
ended March 31, 1996 consisted of other revenues, principally attributable to
roaming charges.
 
     Revenue in all categories, except activation fees and equipment sales,
increased significantly for the quarter ended March 31, 1996 compared to the
quarter ended March 31, 1995. Airtime charges were Ps 8.6 billion (US$8.2
million) for the quarter ended March 31, 1996, compared to Ps 1.1 billion
(US$1.1 million) for the quarter ended March 31, 1995. This reflected the
increased number of subscribers and an increase in fees compared to the quarter
ended March 31, 1995. In addition, the average billed rate per minute increased
136% from Ps 210 (US$0.20) for the quarter ended March 31, 1995 to Ps 497
(US$0.48) for the quarter ended March 31, 1996 primarily because of the increase
in fees compared to the quarter ended March 31,
 
                                       43

1995 and the inclusion of interconnection revenues for incoming calls. This was
partially offset by a reduction in average minutes per subscriber from 237
minutes to 234 minutes.
 
     Monthly fixed fees were Ps 4.4 billion (US$4.2 million) for the quarter
ended March 31, 1996, compared to Ps 1.7 billion (US$1.6 million) for the
quarter ended March 31, 1995. This increase reflected the increased subscriber
base and the increased average monthly fixed fee per subscriber, which increased
12% from Ps 41,014 (US$39) for the quarter ended March 31, 1995 to Ps 45,947
(US$44) for the quarter ended March 31, 1996.
 
     Revenue from equipment sales decreased from Ps 4.1 billion (US$3.9 million)
for the quarter ended March 31, 1995 to Ps 2.0 billion (US$1.9 million) for the
quarter ended March 31, 1996, due to the factors discussed above.
 
     Activation fees decreased from Ps 0.6 billion (US$0.6 million) for the
quarter ended March 31, 1995 to Ps 0.1 billion (US$0.1 million) for the quarter
ended March 31, 1996, as a result of the promotional campaign commenced by the
Company in December 1995, pursuant to which the Company does not charge any
activation fee.
 
  Costs and Expenses
 
     Costs and expenses were Ps 18.7 billion (US$17.8 million), an increase of
50% over Ps 12.5 billion (US$12.0 million) for the three-month period ended
March 31, 1995. Such increase reflected the overall growth in the business and,
in particular, an increase in operating costs because of the substantial
increase in the number of subscribers.
 
     Operating costs were Ps 7.9 billion (US$7.6 million), an increase over the
amount for the three-month period ended March 31, 1995 of Ps 4.3 billion (US$4.1
million), and represented 46% of revenue compared to 57% for the three-month
period ended March 31, 1995, primarily reflecting the increase in the leasing of
equipment, interconnection costs, roaming fees and the quarterly royalty payment
to the government. Included in operating costs were cost of equipment sold of Ps
2.4 billion (US$2.3 million) for the three-month period ended March 31, 1996,
compared to Ps 3.6 billion (US$3.4 million) for the three-month period ended
March 31, 1995, and interconnection charges and the quarterly royalty payment to
the government which totalled Ps 2.5 billion (US$2.4 million) for the
three-month period ended March 31, 1996 compared to Ps 0.6 billion (US$0.6
million) for the three-month period ended March 31, 1995.
 
     Marketing and selling expenses were Ps 2.2 billion (US$2.1 million),
compared to Ps 2.8 billion (US$2.7 million) for the three-month period ended
March 31, 1995. Such costs were 13% of revenue for the three-month period ended
March 31, 1996 compared to 37% for the three-month period ended March 31, 1995,
reflecting the realization of economies of scale in sales and marketing.
 
     General and administrative costs were Ps 4.9 billion (US$4.7 million),
compared to Ps 2.9 billion (US$2.8 million) for the three-month period ended
March 31, 1995, reflecting the growth of the Company. Approximately 26% of such
total constituted a provision for bad debt of Ps 1.3 billion (US$1.2 million)
which was related to the actions by the Company to upgrade the quality of its
customer base discussed above. General and administrative costs were 29% of
revenue for the three-month period ended March 31, 1996 compared to 39% for the
three-month period ended March 31, 1995, reflecting the economy of scales
achieved by the Company.
 
     Depreciation and amortization was Ps 3.7 billion (US$3.5 million), compared
to Ps 2.5 billion (US$2.4 million) for the three-month period ended March 31,
1995. Such charges were 22% of revenues for the three-month period ended March
31, 1996 compared to 33% for the three-month period ended March 31, 1995,
resulting from an increase in amortization which was offset by a larger increase
in revenues.

  EBITDA
 
     As a result of the foregoing, EBITDA for the three-month period ended March
31, 1996 was Ps 2.0 billion (US$1.9 million), compared to a negative Ps 2.5
billion (US$2.4 million) for the three-month period ended March 31, 1995. See
note 8 under "Selected Financial and Operating Data".
 
  Operating Loss
 
     As a result of the foregoing, the Company incurred an operating loss of Ps
1.7 billion (US$1.6 million) for the three-month period ended March 31, 1996
compared to an operating loss of Ps 5.0 billion (US$4.8 million) for the
three-month period ended March 31, 1995.
 
  Other Income (Expense)
 
     Other expense, net, for the three-month period ended March 31, 1996
amounted to Ps 3.1 billion (US$3.0 million), compared to other expense, net, of
Ps 2.9 billion (US$2.8 million) for the three-month period ended March 31, 1995.
Other expense consisted of interest expense on indebtedness of Ps 7.2 billion
(US$6.9 million) for the three-month period ended March 31, 1996 compared to Ps
3.3 billion (US$3.2 million) for the three-month period ended March 31, 1995 and
foreign exchange losses on U.S. dollar-denominated indebtedness of Ps 6.9
billion (US$6.6 million) for the three-month period ended March 31, 1996
compared to Ps 5.9 billion (US$5.6 million) for the three-month period ended
March 31, 1995. Such increases were primarily due to the devaluation of the
Peso, as well as higher interest expense due to an increase in average
indebtedness. The foreign exchange losses reflected devaluation of the Peso from
987.65 Pesos to one U.S. dollar at December 31, 1995 to 1,046.00 Pesos to one
U.S. dollar at March 31, 1996. Such other expenses were offset in part primarily
by interest income of Ps 1.2 billion (US$1.1 million) for the three-month period
ended March 31, 1996 compared to Ps 0.4 billion (US$0.4 million) for the
three-month period ended March 31, 1995, and a net monetary correction of Ps
11.1 billion (US$10.6 million) for the three-month period ended March 31, 1996
compared to Ps 6.9 billion (US$6.6 million) for the three-month period ended
March 31, 1995. Of the total interest income for the three-month period ended
March 31, 1996, 76% resulted from investments of excess cash compared to 54% for
the three-month period ended March 31, 1995 and 24% resulted from foreign
exchange gains and other adjustments compared to 46% for the three-month period
ended March 31, 1995.
 
     The increase in the monetary correction resulted primarily from an increase
in the valuation of intangibles and property, plant and equipment, partially
offset by an increase in shareholders' equity for the three-month period ended
March 31, 1996. Of the total monetary correction, 94% was attributable to
balance sheet account adjustments and the remainder to income statement account
adjustments.
 
  Net Loss
 
     As a result of the foregoing, the Company had a net loss of Ps 5.2 billion
(US$5.0 million) for the three-month period ended March 31, 1996, compared to a
net loss of Ps 7.9 billion (US$7.6 million) for the three-month period ended
March 31, 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     As is typical with the commencement of a cellular business, the Company has
required substantial capital to purchase the Concession, construct its network
and fund operations. Because of the start-up nature of its operations, such
requirements have been largely funded through capital contributions from
shareholders and debt financing rather than cash flow.
 
     The Company's uses of funds to date have included Ps 123.1 billion (actual
Pesos) (US$148.5 million at the April 13, 1994 Representative Market Rate) to
pay for the Concession in 1994, capital expenditures to construct the network of
Ps 37.9 billion (US$36.2 million) in 1994 and Ps 24.8 billion (US$23.7 million)
in 1995, and funds for operations. For the years ended December 31, 1994, and
1995 and the quarter ended March 31, 1996, net cash used in operating activities
was Ps 3.7 billion (US$3.5 million), Ps 46.0 billion
 
                                       45

(US$44.0 million) and Ps 15.2 billion (US$14.5 million), respectively. For the
years ended December 31, 1994 and 1995 and the quarter ended March 31, 1996, net
cash used in investing activities was Ps 207.2 billion (US$198.1 million) and Ps
27.2 billion (US$26.0 million) and Ps 3.2 billion (US$3.0 million),
respectively.
 
     As of March 31, 1996 the Company had raised from its shareholders through
the issuance of common stock an aggregate amount of Ps 96.6 billion (US$92.4
million).
 
     During 1994, the Company borrowed, net of repayments, Ps 111.7 billion
(US$106.8 million) under bank loans, of which approximately 95% was U.S.
dollar-denominated indebtedness. During 1995, the Company borrowed, net of
repayments, Ps 74.3 billion (US$71.1 million), of which approximately 95% was
Peso-denominated indebtedness. During the quarter ended March 31, 1996, the
Company borrowed, net of repayments, Ps 14.2 billion (US$13.6 million, of which
approximately 31% was Peso-denominated indebtedness.
 
     As of December 31, 1995 and March 31, 1996, the Company's total
indebtedness was Ps 167.3 billion (US$160.0 million) and Ps 167.6 billion
(US$160.2 million), respectively. Of such total, Ps 83.7 billion (US$80.0
million) and Ps 84.2 billion (US$80.5 million), respectively was long-term debt
and Ps 83.6 billion (US$80.0 million) and Ps 83.4 billion (US$79.7 million),
respectively was short-term debt. In addition, of the total indebtedness, Ps
53.4 billion and Ps 53.3 billion, respectively, was Peso-denominated debt and Ps
113.9 billion and Ps 114.3 billion, respectively, was U.S. dollar-denominated
debt. The Company's cash and cash equivalents as of December 31, 1995 and March
31, 1996 was Ps 6.7 billion (US$6.4 million) and Ps 15.0 billion (US$14.3
million), respectively.
 
     In June 1996, the Company refinanced US$157 million of its indebtedness
with proceeds of the Offering and the Bank Facility. The Company expects to use
the remaining net proceeds of the Offering and the Bank Facility to fund
construction of the network and for working capital.
 
     In addition to the indebtedness represented by the Notes and the Bank
Facility, the Company as of June 30, 1996 had approximately US$1.8 million of
other indebtedness consisting primarily of letters of credit. The Company also
has obligations under leases which are not capitalized in accordance with
Colombian GAAP. See note 7 to the financial statements of the Company.
 
     The Company expects that the capital expenditures needed to complete
construction of its network (including planned upgrades by 1999) will aggregate
approximately US$54 million, of which approximately US$13.0 million is expected
to be incurred in each of fiscal 1996 and fiscal 1997. The Company expects that
its internally generated funds will be sufficient to satisfy debt service
requirements and operational needs as well as such capital requirements needed
to complete the build-out of its network through 1999, and, therefore, does not
expect to need additional financing. However, there can be no assurance that
such funds will be sufficient to satisfy such requirements and needs, and,
accordingly, the Company may need to obtain additional financing.

                                    BUSINESS
 
     Occel is one of only two providers of cellular telecommunications services
in the densely populated western region of Colombia (the "Western Region"). The
Western Region has a population of approximately 12.8 million people (or
approximately 36% of the country's population), and includes the cities of
Medellin and Cali, the second and third largest metropolitan areas in the
country, as well as thirteen other cities with populations in excess of 100,000
each. The Company commenced commercial cellular service in September 1994,
pursuant to a ten-year concession effective as of March 28, 1994, and has
subsequently generated significant growth in total subscribers and revenues. As
of December 31, 1995 and March 31, 1996, the Company had 40,887 and 48,460
reported subscribers, respectively, and realized average monthly revenue per
active subscriber for the quarters ended December 31, 1995 and March 31, 1996 of
US$141.76 and US$143.84, respectively (in actual Pesos translated at the average
Representative Market Rates for the respective quarters).
 
     Since the launch of its service, the Company has sought to rapidly increase
its coverage areas, establish recognition of its "Vozavoz" brand name and
provide a superior quality of service that is equivalent to that provided by
world class operators. As of March 31, 1996, the Company had reached a
penetration level of 0.56% of the population covered by its cellular network,
which included the metropolitan areas of Medellin (with approximately 2.4
million pops), Cali (with approximately 1.8 million pops), Pereira (with
approximately 0.5 million pops), Manizales (with approximately 0.4 million
pops), Armenia (with approximately 0.2 million pops) and other urban areas
(having in the aggregate approximately 0.7 million pops). In addition, the
Company has roaming agreements with other cellular operators which provide its
customers with nationwide coverage throughout Colombia as well as access in
several other countries.
 
     The Company has invested heavily in constructing a state-of-the-art network
which has dual analog and digital capacity and which can support continued
growth in subscribers as well as technologically advanced new services. As of
March 31, 1996, the Company's cellular telecommunications network covered
approximately 67% of the population of the Western Region. The Company had
incurred approximately Ps 57 billion (US$54 million) in capital expenditures
through March 31, 1996 to build its network, and expects to incur approximately
an additional US$51 million to substantially complete its build-out (including
planned upgrades) by 1999.
 
     The Company's headquarters are located at Carrera 55 No. 49-101, Medellin,
Colombia, and its telephone and fax numbers are 574-512-9090 and 574-513-0199,
respectively.
 
COLOMBIAN TELECOMMUNICATIONS INDUSTRY
 
  Overview
 
     Colombia is one of the oldest democracies and most stable economies in
Latin America. Since 1950, Colombia has enjoyed positive real economic growth in
every year, with real compounded average annual growth in its GDP of
approximately 4.5% from 1986 to 1995, one of the highest growth rates in Latin
America. In addition, annual inflation has declined steadily in each of the past
five years from 26.8% in 1991 to 22.6% and 19.5% in 1994 and 1995, respectively.
In recent years, the government's economic growth strategy has encouraged
foreign investment and exports through reduced foreign exchange controls and
lower import quotas and tariffs. The government has also begun to open certain
public services to private sector investment and has commenced privatization of
certain state-owned industries in the power and banking sectors, and is
considering other sectors for privatization. In part as a result of these
policies, foreign investment in Colombia has grown from US$3.5 billion in 1990
to US$6.6 billion in 1995. During the same period, Colombia has achieved
increased diversification of its export base and the value of its exports has
grown from US $6.7 billion to US $9.8 billion. However, Colombia is currently
experiencing political turmoil which could have an adverse effect on the
economy. See "Risk Factors -- Risks Related to Colombian Political, Economic and
Social Factors".

     Despite the growth in the economy and, in particular, the infrastructure in
Colombia in recent years, the country is significantly underserved by existing
wireline operators and demand for phone service substantially outweighs supply
of wireline phone service. As of December 31, 1994, as reported by International
Telecommunication Union, Colombia had only approximately 10 telephone lines per
100 persons. Colombia's wireline penetration compares with other Latin American
countries as follows:

     The Colombian government, recognizing the importance of an effective
telecommunications infrastructure and the role that the telecommunications
industry plays in national development, has taken steps in the last several
years to liberalize Colombia's telecommunications regulatory framework in order
to support the government's goals of increased coverage, modernization and
service diversification. In 1991, the Ministry of Communications opened the
value-added services market to competition. "Value-added services" are defined
as services other than basic telephone service, such as data transmission. In
1992, the Colombian government authorized the granting of cellular
telecommunications service concessions to public-sector, mixed-economy and
private-sector companies and subsequent legislation adopted in 1993 created the
framework for the provision of cellular telecommunications services.
 
     Currently, local wireline telephone service in the Western Region is
provided by six main local and municipal operators, who, through holding
companies, are also shareholders of the Company, as well as by several other
operators which service smaller cities. Wireline penetration in Colombia varies
significantly by city as does the waiting time for wireline service, which
ranges from a few weeks or months in the best markets (including Medellin) to
two years or longer. This can be contrasted with cellular service, where in the
case of the Company to date, service to new customers has generally commenced
within a few days.
 
     Domestic and international long distance wireline service is provided
exclusively by the state-owned Telecom, which has a monopoly on both
international calls and telex services. Cellular operators, pursuant to their
Concessions, can route domestic long-distance calls through their own networks
or through those of the other cellular companies. However, cellular operators
must route all international long distance service through Telecom. In 1995, the
Colombian government announced the opening of the domestic and international
long distance market to competition beginning in 1997, at which time there will
be up to two other licensed operators in addition to Telecom. The Company
believes that the deregulation of the long distance market will, as it has in
other countries, serve to stimulate phone usage, including the usage of cellular
phones, due to the fact that price competition is likely to lower tariffs to the
consumer.
 
  Cellular Concessions
 
     In 1993, the Colombian government initiated an auction process to grant a
limited number of long-term cellular telecommunications concessions throughout
the country. For purposes of this process, Colombia was divided into three
regions (i) the Western Region, (ii) the Eastern Region and (iii) the Atlantic
Region, with each Region having an A Band and a B Band. The government organized
two parallel, but separate, bidding processes for the concessions available in
each Region: (i) public-sector and mixed-economy companies (companies which have
both public sector and private sector shareholders, engage in commercial
activities and are created by special legislation) were permitted to bid for the
A Band concession and (ii) wholly private-sector companies were permitted to bid
for the B Band concession. The Colombian government first

awarded the B Band concessions and then, forty days later, awarded the A Band
concessions, which were priced at a minimum of 95% of the related winning B Band
bids.
 
     In awarding these concessions, the Colombian government considered not only
financial factors, but the underlying technical and operational capabilities of
the various bidders. The completion of the auction process has resulted in a
cellular duopoly similar to that which characterizes the United States, Canada
and most Latin American countries. The government awarded a total of six
concessions, with two concessions in each of the Regions, as follows:

</TABLE>
 
     The concessions were awarded for ten years, with a renewal option, subject
to certain conditions, for an additional ten-year period. The government may
issue additional concessions (though not on the frequencies awarded) after 1999.
 
     The following significant factors distinguish cellular systems in the
Western Region from those in the United States: (i) the early introduction of
digital technology, (ii) the policy of calling party pays and (iii) the ability
to deliver domestic long distance calls without routing such calls through a
long distance carrier. In the United States, cellular networks were originally
constructed using analog technologies. Cellular operators in many United States
markets either have implemented, have begun to implement or today face the need
to implement digital cellular technology, in each case often at significant
cost. In Colombia, the government mandated that cellular operators meet certain
digitalization targets as a condition of their concessions with a requirement
that 10% of the cellular operators' networks be digital by the third year of
operation, 30% by the fifth year and 50% by the eighth year. Cellular networks
in Colombia, including the Company's, are being constructed using TDMA
technology, the most widely used cellular digital standard in North America. The
policy of calling party pays differs from that in the United States where the
cellular subscriber pays for the incoming call. The Company believes that the
policy of calling party pays has resulted in a much higher percentage of
incoming traffic and more usage overall by its subscribers as they are more
likely to give their telephone number to callers since they are not charged for
the incoming call. The policy also encourages people to keep their phones turned
on. In the United States, cellular operators are required to route long-distance
calls through a long distance carrier and then share the resulting revenue. In
contrast, the Concession allows the Company to deliver calls anywhere in the
Western Region when it has the capability to do so, without routing such calls
through a long distance carrier. Accordingly, the Company is not required to
share revenues for such calls with another carrier.
 
  The Western Region
 
     The Western Region includes the departments of Antioquia, Caldas, Cauca,
Choco, Narino, Quindio, Risaralda and Valle. It has an area of 209,000 square
kilometers, representing 18% of the country's total area. The population of 12.8
million inhabitants represents 36% of the total population of Colombia. The
region is bounded by 1,300 kilometers of Pacific and 290 kilometers of Atlantic
coastline making it a strategically important area. The Western Region includes
the metropolitan areas of Medellin and Cali, the second and third largest cities
in Colombia, with populations of 2.4 million and 1.8 million, respectively. The
Western Region includes the Buenaventura Port, on the Pacific coast, which
handles approximately half of all exports of the country.
 
     The Western Region generates one third of Colombia's Gross National
Product, mainly with urban economic activities. Many of the largest national
manufacturing, agricultural and commercial companies are located in the Western
Region. Additionally, 50% of Colombia's hydro-electric power, which represents
76% of the total electric power, is produced in the region.

     In the Western Region there are four major and many smaller airports, and
four industrial and commercial "free zones" designed to attract industry and
commerce. The Western Railroad, which is undergoing a modernization and
enhancement program, runs through about 75% of the Western Region. In addition,
the Panamerican Highway, which runs from Alaska to the southern tip of Latin
America, covers the entire length of the Western Region.

  Growth of Cellular Industry
 
     Since the commencement of service in 1994, the Colombian cellular industry
has experienced significant growth. On September 30, 1994, total reported
subscribers in Colombia equaled 25,243. By December 31, 1995, the most recently
available period, the total number of reported subscribers had grown to 274,590,
according to the Ministry of Communications, and represents a penetration rate
for the total Colombian population of 0.78%. This compares favorably with
estimated penetration and growth rates in other Latin

Western Region, Comcel in the Eastern Region, and Celcaribe in the Atlantic
Region. The main purpose of REDCEL is to establish a strong competitive position
for the mixed-economy cellular companies by offering to their users access to
nationwide cellular coverage through roaming agreements. The three companies
also cooperate to provide to their respective customers (i) technical assistance
throughout Colombia, (ii) access to international roaming with a greater number
of North, Central and South American countries, (iii) access to common
information lines and short code access numbers throughout Colombia, (iv) a
nationwide payment system through selected banks and (v) a membership card that
will offer special discounts at selective outlets. They also intend to cooperate
in handling customer complaints and in fraud detection and prevention
procedures.
 
     In July 1995, the Colombian cellular companies formed the Colombian
Cellular Industry Association (Asociacion de la Industria Celular de Colombia)
("ASOCEL"), an industry association, and appointed Carlos Holguin, a former
Minister of Communications and a former President of the Colombian Senate, as
its president. ASOCEL was created to promote the development and consolidation
of the cellular industry in Colombia and focus on common industry concerns.
ASOCEL also plans to (i) address operational issues, including fraud control and
credit checking procedures, (ii) participate in the drafting of and the
promotion of laws and regulations that benefit the cellular industry and (iii)
promote research on cellular and telecommunications issues.
 
COMPANY STRENGTHS
 
     Since its inception in 1992, the Company has capitalized on the market
opportunity created by the aforementioned factors. The Company has constructed a
network that covers most of the major population areas in the Western Region,
built its subscriber base and recognition of its "Vozavoz" brand name, and
developed a variety of service offerings to appeal to diverse groups of
consumers. The Company believes that it is well positioned to achieve continued
growth in its subscriber base and cash flow by virtue of a number of factors,
including the following:
 
          - Attractive Concession Area.  The Western Region has many
     characteristics which create an attractive cellular market, including
     principally a diverse and well developed economy. The region generates over
     one third of Colombia's gross national product and includes a substantial
     part of the country's commerce and manufacturing and agricultural
     industries. Approximately 71% of the national coffee production and 55% of
     the national banana production, the country's two largest agricultural
     commodities, are produced in the Western Region. Approximately half of
     Colombia's hydro-electric power is produced in the Western Region and
     approximately half of the country's exports pass through the Western
     Region's Buenaventura Port. The Western Region also houses the Colombian
     headquarters of 21 of the top 50 industrial and commercial companies in
     Colombia, including Carvajal S.A., Noel S.A. and Colgate Palmolive y Cia
     S.A. In addition, the headquarters of 11 of the top 25 financial
     institutions in
 
                                       53
<PAGE>   58
 
     Colombia, including Banco Industrial Colombiano S.A., Conavi S.A. and Banco
     Popular S.A., are located in the Western Region.
 
          - Favorable Demographics.  The metropolitan areas of Medellin and
     Cali, with populations of 2.4 million and 1.8 million, respectively, are
     major economic centers in the country, are densely populated and have
     significant concentrations of affluence. The Company has experienced
     considerable demand in these areas despite their relatively high wireline
     penetration rates. The Company believes this reflects the advantages of
     cellular service, such as personal safety, convenience and mobility, to
     diverse segments of the population, including professional workers as well
     as small businessmen, contractors and other tradesmen who work on location.
 
          - Superior Customer Service.  The Company believes that quality of
     customer service is a key competitive factor in the Colombian duopolistic
     market. The provision of excellent customer service is an essential element
     in the Company's business strategy and an inherent part of its corporate
     culture. Staff in all areas of the Company attend a five-day customer
     service training program, and the Company's specialized customer service
     team (consisting of 91 members as of March 31, 1996) provide service 24
     hours per day, responding to telephone queries from three regional centers.
     On average, the customer service team answers 2000-3000 calls per working
     day (74.2% within 20 seconds in March 1996) and answers 1000 letters per
     month. New customers generally receive service within a few days, as well
     as individual welcome calls to confirm that they are not experiencing
     problems. The Company's dedication to customer service is also illustrated
     by the provision of its free "*911" emergency service and by the provision
     of nationwide service through roaming agreements.
 
          - High Quality Advanced Network.  Due to the recent development of the
     cellular telecommunications industry in Colombia, Occel has been able to
     construct a dual analog/digital network from inception using state of the
     art technology under a TDMA platform with equipment supplied by Northern
     Telecom. The Company believes a significant component of offering the
     highest quality of customer service entails providing its customers
     continual access to its network. The Company measures this in terms of the
     customers' ability to make a call whenever desired and the probability that
     a call will not fail (a "dropped call") once it is connected. During the
     six-month period ended March 31, 1996, the Company connected more than 97%
     of attempted calls and dropped less than 3% of total calls made. The
     Company believes its dual analog/digital network provides it with the
     ability to quickly and cost-effectively offer more digital capacity in its
     network as the demand for digital service increases without incurring the
     problems and costs experienced by many North American operators who are
     encountering operational difficulties and significant expenses as they seek
     to upgrade their networks to digital. As of March 31, 1996, approximately
     30% of the Company's subscribers used digital handsets and the Company
     expects that more than half of its customers will be using digital
     equipment by the end of 1997. The Company expects to realize significant
     benefits from increasing the usage of digital equipment, such as increased
     system capacity, reduced operating expenses and additional revenue from the
     sale of digital-specific services such as "caller i.d." and voice mail
     message waiting notification. The Company believes its network has
     sufficient capacity to accommodate projected growth in subscribers and has
     the flexibility to handle new services.
 
          - Numerous Service Offerings.  The Company provides the basic cellular
     service options offered by world class operators, such as call transfer,
     call waiting, voice mail and national and international roaming. In
     addition, the Company offers several other services that are aimed at the
     particular needs of its customer base and that enhance the Company's brand
     name and image as a provider of the highest quality service. These include
     its free "*911" emergency service (which is trademarked within Colombia),
     where a customer can call *911 at any time and be connected to a Company
     representative who can then contact the police, the fire department, an
     automobile towing service or any other emergency service desired by the
     customer. This service has proved especially popular because the Colombian
     wireline companies do not have a universal emergency service such as the
     911 service in the United States. The Company also offers value-priced
     services that it believes attract different segments of the population than
     traditional users of cellular services, thereby enhancing its penetration
     rate. The Company offers "Beepervoz", a budget service in which the
     customer can only receive calls and make
 
                                       54
<PAGE>   59
 
     outgoing calls to the Company's *911 emergency service. This service
     provides a low-cost introduction to cellular service and is also designed
     to compete with pagers. In addition, the Company's "Fijovoz" service
     provides cellular service from a fixed wireless phone in the home or office
     for a lower price than its mobile cellular service. This option is designed
     to appeal to customers seeking to avoid the long waiting time for wireline
     service or who are otherwise dissatisfied with wireline service but who do
     not need the mobility of full cellular service. The Company also believes a
     number of these budget-conscious customers will ultimately upgrade to
     higher classes of service over time.
 
          - Management of Churn.  The Company's monthly average churn rate for
     the year ended December 31, 1995, was 3.2%. This reflected a churn rate of
     approximately 2% per month for most of the year, except between August and
     October when churn was approximately 8% per month. This temporary increase
     in churn resulted from Company-initiated disconnections in order to upgrade
     the quality of its customer base. The Company estimates that the monthly
     churn rate for the first six months of 1996 averaged 2.9%, in part because
     there was a similar month of Company-initiated disconnections, which may
     occur from time to time in the future. The Company recognizes that managing
     customer churn is an important factor in maximizing revenues and cash flow.
     In order to minimize churn caused by customers voluntarily terminating
     service, the Company aims to ensure that its services remain competitive
     and has one-year customer contracts that contain penalties for early
     termination. To reduce Company-initiated disconnections resulting from
     non-payment, beginning in August 1995, the Company implemented policies
     which require thorough credit checks for new customers, encourage direct
     debit payment plans, and impose gradual restrictions on service once
     payment dates have been missed. For instance, customers' outgoing calls are
     automatically routed to customer service if payment is not received within
     ten days of the final due date, and service is temporarily disconnected in
     the event payment is not received within ten more days. The Company
     believes that these policies reduce the likelihood that customers will run
     up excessive debts, thus enhancing the likelihood of settlement and
     reconnection.
 
          - Experienced Management Team.  The members of the Company's senior
     management team have substantial experience in the telecommunications
     industry as well as in the public and private sectors in the Western
     Region. Many of them worked for local telephone companies and public
     utilities in the Western Region and participated in the development of
     Colombia's cellular regulatory regime. In addition, an executive of C&W,
     was seconded to, and is employed by, the Company as a member of the
     Company's senior management.
 
BUSINESS STRATEGY
 
     The Company's strategy is to continue to capitalize on the high potential
demand for cellular telecommunication services and favorable demographic
characteristics of its concession area to maximize revenues and cash flow from
its cellular business through increased market penetration and subscriber usage.
The Company intends to achieve these objectives by completing construction of
its network, implementing aggressive marketing efforts to attract and retain
additional subscribers and continuing to provide superior customer service,
reliability and a wide range of value-added optional services. The Company's
commercial slogan is "Seriousness, Security and Service", which is intended to
convey the high degree of professionalism with which the Company seeks to
provide its services, the security (i.e., increased personal safety) such
services provide to its customers, and the Company's responsiveness to its
customers. The Company will also evaluate and may participate in, future
opportunities in related wireless technology businesses in order to enhance its
position as a leading provider of such services.
 
SALES AND MARKETING
 
     In order to implement its business strategy effectively, the Company has
focused its marketing efforts on (i) establishing brandname image and
recognition of its primary "Vozavoz" service and related product offerings, (ii)
targeting high quality, high use customer segments which have specific
identifiable needs through the use of a well trained sales network, and (iii)
differentiating the Company from its competitor on the basis of a superior
quality of service rather than price.

  Marketing Programs
 
     The Company uses both mass media campaigns and direct marketing through its
internal sales force and independent distributors to reach potential customers.
Mass media campaigns have been used by the Company to create awareness and
promote the benefits of cellular services and to position its Vozavoz brandname
and commercial slogan. The Company employs, among other media, billboards,
television, radio and direct mail as well as the sponsorship of sporting events
and educational seminars. Direct marketing efforts have been used by the Company
to reach priority segments of its target market, such as professionals and small
businessmen who travel or work on location. The initial selection of the
priority segments within the Company's target market was made using a demand
model created by the Company with the help of C&W, which has utilized similar
models in other emerging markets. The model took into account factors such as
market size, adoption rate, income levels and the need for mobile
communications, for various segments of the population. Over time, the Company
has identified additional factors that promote the use of cellular services,
such as personal safety, and broadened its marketing efforts to target
additional population groups.
 
  Sales Network
 
     The Company offers its cellular services to potential subscribers
principally through (i) direct marketing activities by its internal sales
representatives, which primarily target corporate accounts, government accounts
and high volume customers, and (ii) through its sales centers and its exclusive
network of independent distributors, both of which target residential customers
and small businesses. The Company believes that this mixed distribution approach
allows the Company to reach a broader customer base while avoiding the cost of a
large direct sales force. It also allows the Company to capitalize on the
distributors' knowledge of local markets and reduce inventory risks. As of
December 31, 1995, approximately 60% of new subscriber activations were effected
through the Company's distributor network and 40% through its internal sales
representatives.
 
     As of March 31, 1996, the Company's sales and distribution network
consisted of approximately 100 internal sales people and approximately 240 sales
people from independent distributors and subdistributors. The Company operates
five primary sales centers which are centrally located in Cali, Medellin,
Pereira, Manizales and Armenia and which provide both sales and customer support
services such as payment reception, repairs, insurance and billing claims
attention. The independent distributors operate 23 satellite distribution sales
offices primarily serving regional areas, suburbs and smaller towns. Although
most of the distributors' sales offices do not provide customer support
services, customers needing assistance are referred to centralized customer
service representatives. In addition to the Company-owned and operated sales
offices and the independent distributors' sales offices, customers can sign up
for the Company's service through 36 subdistributors, who operate 20 retail
stores selling cellular services, telephones and complementary products. The
breadth and diversity of the Company's sales and distribution network provide
its potential and existing customers with the benefits of convenient locations,
extended service hours, comprehensive phone and accessory selection and highly
trained sales and service staff.
 
     The Company's current independent distributors are locally established
firms, most of them dedicated to the communications business. Some specialized
distributors, such as Cellstar, are new in the Colombian market and are
dedicated exclusively to the cellular business. The independent distributors may
not represent the Company's competitor in the Western Region, but may and do
engage in other related businesses. The Company has contracts with the
independent distributors which are subject to certain sales, service and quality
standards. The independent distributors are paid a commission for upfront
revenues which could be affected if performance standards are not met. The
independent distributors also receive an ongoing residual commission which is
based on the collected revenues of airtime charges and monthly fixed fees. A
portion of the independent distributors' sales commission is pooled and used for
promotion and advertising pursuant to a cooperative marketing program. The
Company believes these arrangements encourage its distributors to attract and
retain long-term, high-quality customers. Subdistributors have contracts with
the independent distributors. The subdistributors are paid a commission based on
their sales, directly by the independent distributors.

  Customer Service and Expanded Service Offerings
 
     The Company's commitment to the provision of excellent customer service, as
reflected in the slogan, "Service, Seriousness and Security" is an intrinsic
element of its corporate strategy. The Company believes that in the cellular
market, the provision of superior customer service is the only differentiating
factor which can be continuously sustained, and has accordingly developed a
strategy which is service orientated. The high levels of service which the
Company provides and will continue to provide have been realized by setting
exacting service related performance objectives, by employing a skilled and
qualified workforce which is trained to rapidly resolve problems, by providing
customer service training for all staff and by investing in the technology,
products and processes required to deliver world class performance levels.
 
     Service related performance targets relate to the times required for
responding to customer queries and requests, to the quality of such responses
and to the performance of the network. The Company's specialized customer
service team of 91 members (as of March 31, 1996) provides 24 hour response to
telephone queries from three regional centers, answering 2000-3000 calls per
working day (74.2% within 20 seconds during March 1996), answering 1000 letters
per month and attending customer queries in eight different sales and service
locations.
 
     To aid its customer service team, the Company has invested in an advanced
Automatic Call Distribution system (ACD) for managing customers' calls, and a
state of the art Network Management Center which is staffed 24 hours a day to
enable rapid identification and resolution of network problems. An electronic
network links the Company's main sites providing access to E-mail and to the
main databases to provide rapid access to information required to solve customer
problems. Customer handset repairs are carried out by trained staff at the main
repair center in Medellin and at local centers in Cali and Pereira with only the
more complex problems being sent to the manufacturers for resolution. Customers
are typically activated within an hour of credit approval, and time for the
credit approval takes between an hour and a couple of days depending on the
complexity of the case and the amount of supplementary information required. In
addition, the network has been designed and is maintained for optimum
reliability, and during the six-month period prior to March 1996 the Company
connected more than 97% of attempted calls and dropped less than 3% of total
calls made.
 
     All Company employees attend a five-day customer service training program
which provides standards and formal skills to support the Company's commitment
to achieving the highest customer service standards. Employees are also actively
encouraged to take initiative to facilitate the resolution of customer problems.
 
OPERATIONS
 
  Services Offered
 
     In addition to basic incoming and outgoing service, the Company currently
provides all of the supplemental types of cellular services, such as call
transfer, call waiting, three-way conference calling and voice mail, that are
typically offered by most cellular operators in major industrial economies. In
addition to these services, the Company currently offers services not
customarily offered by cellular operators in other countries which are specially
suited to the needs of the Colombian market. Furthermore, certain of these
services are not available to Colombian wireline customers generally. By
offering such services, the Company believes it enhances its image as a provider
of the highest quality service. Some of these services are value-priced services
that the Company believes attract a different segment of the population than the
typical customer of traditional United States cellular services, thereby
enhancing the Company's penetration rate and generating additional revenue. The
Company also believes a number of the budget-conscious customers who currently
subscribe to the value-priced services offered by the Company will upgrade to
higher classes of service over time. In the future, the Company also plans to
offer additional services that capitalize on the digital capabilities of its
TDMA network, as described below.
 
                                       57
<PAGE>   62
 
          The Company's current primary and supplemental services are listed
     below:
 
          Primary Services
 
        Vozavoz.  The Company's basic cellular service consists primarily of its
        "Vozavoz" service. The basic features of Vozavoz include local cellular
        service, national coverage and 24-hour customer service. The Company
        offers to its Vozavoz customers automatic roaming coverage services
        throughout Colombia in association with the A Band operators. In
        addition, the Company offers automatic connection with wireline services
        and local and long distance wireline providers, giving its customers
        access to all Colombian wireline subscribers. In addition, the Company
        offers personalized customer service and information services 24 hours a
        day, seven days a week, which can be reached by cellular and wireline
        telephones.
 
        Fijovoz.  Fijovoz is a value-priced basic service offered by the Company
        that consists of a fixed cellular phone. Fijovoz is designed to appeal
        in particular to customers in areas with waiting lists for wireline
        services or who are otherwise dissatisfied with wireline services and
        who do not need the mobility of a traditional cellular phone. This
        service offers the same cellular technology of mobile handsets but using
        a set that is fixed at the subscriber location, providing an
        economically priced cellular service to subscribers which can be
        activated generally within a few days.
 
        Beepervoz.  With Beepervoz, which is another value-priced primary
        service offered by the Company, the subscriber receives a handset that
        is programmed only to receive incoming calls and to make outgoing calls
        only to the Company's *911 emergency service, customer service and,
        optionally, voice mail. This service is designed to appeal in particular
        to customers with safety and security concerns, customers with
        travelling sales forces and customers who need permanent contact with
        their offices. Beepervoz provides a low-cost introduction to cellular
        service and is also designed to compete with paging services. Certain of
        the Company's Beepervoz customers have upgraded to higher classes of
        service, and the Company believes that additional Beepervoz customers
        will ultimately upgrade in the future.
 
          Supplemental Services
 
        In addition to traditional premium cellular services such as call
        transfer, call waiting and three-way conference calling, which the
        Company offers its subscribers for an additional cost, the Company
        currently offers the following supplemental services, some of which
        produce additional revenue for the Company as noted below:
 
        Vozexpress.  Vozexpress is a voice mail service which receives and
        stores messages for subscribers when they do not answer the incoming
        calls. Vozexpress can be obtained for a fee as a supplement to any of
        the Company's basic services.
 
        *911 Vozavoz Emergency Service.  Centralized emergency services like the
        "911" emergency service in the United States are not available in
        Colombia, where the population has to call directly to the respective
        emergency service. The Company offers to its subscriber its "*911"
        service, in which a subscriber can call the Company at any time by
        dialing *911 and then be transferred by one of the Company's operators
        to the appropriate emergency service, including the fire department,
        police, medical emergency services and vehicle towing services. The
        Company's *911 service is trademarked within Colombia. The Company
        believes that this service, which is free to its customers who have
        purchased any of its basic services, is particularly important to, and
        is a primary driver in attracting, many of its customers given the high
        value placed on security and safety in Colombia.
 
        Detailed Billing Services.  As part of its customer service orientation,
        the Company provides free of charge a wide array of billing details to
        its subscribers. This information includes a list of all calls made
        (including free calls), the date and time of calls and the duration and
        the cost of calls. By contrast, local wireline companies typically
        provide such information only for long distance calls.
 
        International Roaming.  As a convenience to its Vozavoz customers who
        are travelling, the Company offers roaming services in other countries,
        including currently the United States, Canada,
 
                                       58
<PAGE>   63
 
        Venezuela, Ecuador and certain countries in the Caribbean where C&W is
        the mobile operator. This service allows the Company's customers to
        place calls from another country to participating countries or to
        Colombia. In some cases, the Company has roaming arrangements with
        operators in such countries pursuant to which the Company collects from
        the subscriber and forwards to such operators the charges for such
        calls. In other cases, the Company's subscribers pay for such calls
        directly. The Company does not charge an additional fee for this
        service.
 
        International Long Distance.  The Company offers connection to the
        Colombian international long distance operator, Telecom. This service
        allows calls to be made from Colombia to another country. The Company
        conducts a supplementary credit check on any customer applying for this
        service. However, the Company does not charge any fee (other than
        airtime) for the provision of this service.
 
        Vozseguro.  Vozseguro is an insurance service for the cellular handsets
        and other supplementary equipment which protects against theft and
        damage. More than 40% of new customers purchase this service.
 
          Future Services
 
        The Company is also planning to introduce new value-added services such
        as data transmission, internet access, caller identification and
        messaging services. These products capitalize on the digital
        capabilities of TDMA and make use of the handset screen to display
        information such as the calling party's identification, a brief message
        or information from a central data base.
 
  Pricing Plans
 
     The pricing structure of the Company's services consists of four basic
components: (i) activation fees, (ii) monthly service fees, (iii) airtime fees
and roaming charges and (iv) fees for supplemental value-added services. In
addition, subscribers are required to purchase a mobile cellular telephone and
to pay usage charges with respect to interconnection to the national wireline
network.
 
     Currently, the Company's subscribers pay a monthly service fee which ranges
from Ps 17,500 (US$16.73) for Beepervoz to Ps 44,000 (US$42.07) for Vozavoz or
as much as Ps 80,000 (US$76.48) for Vozavoz with 155 free minutes of service per
month. Airtime charges for outgoing calls range from Ps 275 (US$0.26) per minute
to Ps 790 (US$0.76) per minute during peak hours and from Ps 230 (US$0.22) per
minute to Ps 630 (US$0.60) per minute during nonpeak hours, in each case
depending on the tariff plan selected. As of December, 1995, the Company began a
promotional campaign pursuant to which it does not charge any activation fee.
See "Management's Discussion and Analysis of Financial Conditions and Results of
Operations".
 
     The Company modifies its prices from time to time to correspond with
marketing campaigns, to respond to competitive pressures, as well as to adjust
to inflation. In the first quarter of 1995, there was a significant price
competition between the Company and Cocelco, which resulted in significant,
temporary reductions in most categories of charges. The Company's prices have
since returned to levels approximating those in effect at the end of 1994. Such
price competition resulted in a significant increase in subscribers, although
many of these were later removed by the Company from its active subscriber
rolls. Currently, both the Company and Cocelco are offering promotions in which
activation fees are free, but airtime charges have actually been raised. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations".
 
     Although the rates and fees charged by cellular operators in Colombia are
currently not fixed by the Colombian government, cellular operators must
communicate to the TRC all their rates and fees and advise existing customers of
any changes.

     The Company uses a billing and customer management system developed by SEMA
UK Limited, a specialized United Kingdom company whose systems are utilized by
numerous international cellular companies. The accuracy and flexibility of the
Company's billing and customer management system are key to
 
                                       59
<PAGE>   64
 
efficiently serve its subscribers and to generate subscriber information vital
to the Company's management. The system currently permits the Company to bill
its customers monthly with a detailed billing statement, including itemized
local and long-distance calls. In contrast, local wireline companies typically
give equivalent details only with respect to long-distance calls, and Cocelco
currently charges a fee for such service. The Company also uses information from
the system to analyze the effects of price changes and promotional and
advertising campaigns as well as subscriber use patterns and to prevent fraud.
 
  Management of Churn
 
     The Company's monthly average churn rate for the year ended December 31,
1995, was 3.2%. This reflected a churn rate of approximately 2% per month for
most of the year, except between August and October when churn was approximately
8% per month. This temporary increase in churn resulted from Company-initiated
disconnections in order to upgrade the quality of its customer base. In
particular, the Company disconnected many customers who joined during the price
competition of the first quarter of 1995 who were behind in payments. The
Company estimates that the monthly churn rate for the first six months of 1996
averaged 2.9%, in part because there was a similar month of Company-initiated
disconnections, which may occur from time to time in the future. The Company
recognizes that managing customer churn is an important factor in maximizing
revenues and cash flow. In order to minimize churn caused by customers
voluntarily terminating service, the Company aims to ensure that its services
remain competitive and has one-year customer contracts that contain penalties
for early termination. To reduce Company-initiated disconnections resulting from
non-payment, beginning in August 1995, the Company implemented policies which
require thorough credit checks for new customers, encourage direct debit payment
plans, and impose gradual restrictions on service once payment dates are missed.
For instance, customers' outgoing calls are automatically routed to customer
service if payment is not received within ten days of the final due date, and
service is temporarily disconnected in the event payment is not received within
ten more days. The Company believes that these policies should reduce the
likelihood that customers will run up excessive debts, thus enhancing the
likelihood of settlement and reconnection.
 
  Fraud Detection and Prevention
 
     The Company currently uses a fraud detection system developed by C&W which
analyzes call data records to identify abnormal calling patterns and cloned
cellular phones and to take corrective actions promptly. In addition, the
Company's billing system generates daily reports on customers that have exceeded
their preassigned credit limits. Based on these reports, customers are contacted
by credit control staff of the Company or deactivated, depending on the
circumstances.
 
     To reduce the incidence of fraud in its operations, the Company has
developed a fraud prevention program that includes (i) background checks of its
employees, (ii) fraud awareness and prevention training, (iii) restrictions on
international calls to certain high risk destinations and restrictions on
three-way calling by customers with international direct dial access. The latter
restrictions prevent a caller from calling a cloned phone with three-way calling
and international access and thereby make an unbillable international call.
 
     In addition to the mentioned fraud detection and prevention methods, the
Company conducts credit checks and verifies the identity of each new subscriber
to reduce the incidence of fraudulent application. Moreover, as mandated by the
Colombian government, the Company is required to ensure that, at the time of
activation, all its subscribers register their phone with the police and carry
an identification card with the phone specifications. The Company and the other
A Band operators also share information on bad accounts and cooperate in
developing and implementing fraud detection systems.
 
  Equipment Supply
 
     The mobile equipment used by the Company consists of handsets and
accessories which are available for purchase from multiple sources. In order to
achieve significant cost savings from volume purchases, the Company currently
purchases its mobile equipment from Cellstar (a distributor for Motorola) and
Nokia under short-term arrangements. The Company has not experienced material
disruptions in supply and
 
                                       60
<PAGE>   65
 
anticipates that equipment will continue to be available to the Company from
many sources in the foreseeable future.
 
     Although the Company generally sells digital handsets at cost, it has
offered subsidies for purchasing such handsets during specific promotional
periods. At present, the Company sells only digital handsets to new Vozavoz
customers, and encourages its existing customers to trade in analog handsets.
Analog handsets are currently sold principally to Beepervoz and Fijovoz
subscribers. In addition, the Company recently commenced a handset leasing
program to expand its subscriber base.
 
NETWORK DESIGN AND OPERATION
 
  Network Design
 
     The Company developed its network design in conjunction with C&W. The
Company also incorporated service quality, redundancy and coverage objectives
based on the best practices in North America. To help meet these objectives, the
Company has employed sophisticated network design tools such as PLANET, a
software-based planning tool developed by Mobile System International ("MSI").
In addition, the Company's network was designed to take advantage of its
microwave transmission system along with multiple interconnect points with
wireline telephone companies in order to ensure that the Company has the ability
to carry a significant portion of its traffic on its own network and,
correspondingly, to reduce the Company's reliance on other networks over which
the Company has no control. In addition, the Company's design objectives require
that the network be sufficiently versatile to support a variety of desired
value-added cellular services such as call forwarding, call transfer, call
waiting, three-way conference calling, voice mail, caller identification,
cellular data transmission and technical support for fixed cellular operations.
 
  Capacity
 
     Each cellular telecommunications network is planned and constructed to meet
a certain level of subscriber density and traffic demand. Once this level is
exceeded, a cellular operator must take steps to increase network capacity in
order to maintain service standards. Such capacity increases can be accomplished
by increasing digital penetration and by using such techniques as sectorization
and cell splitting. Other techniques have been developed by operators and
infrastructure manufacturers to ensure service quality at minimal cost,
including microcells. Cellular telecommunications networks are typically
characterized by relatively high fixed costs and relatively low variable costs.
Until technological limitations on network capacity are reached, additional
capacity can usually be added in increments that closely match demand and at
less than the proportionate cost of initial capacity. At December 31, 1995, the
Company had a capacity margin of approximately 20%, with 65% of the network
capacity being analog and the rest digital.
 
  Network Expansion and Coverage
 
     The Company develops its cellular service areas by building new base
stations and adding cells to existing base stations. Such development is done
for the purpose of increasing capacity and improving coverage in direct response
to projected subscriber demand. The Company initially focused on providing
service to the top five cities in the Western Region -- Medellin, Cali, Pereira,
Manizales and Armenia -- and their surrounding metropolitan areas. The Company
continues to expand its network to cover as broad a geographical area as is
economically feasible, as geographic coverage is a key variable in the consumer
purchasing decision. Expansion of the network capacity also enhances the
Company's ability to provide service in the Cali and Medellin metropolitan areas
where the demand for cellular services continues to increase. As of December 31,
1995 the Company's network covered 65% of the population of the Western Region.
The Company has incurred approximately Ps 57 billion (US$54 million) in capital
expenditures through March 31, 1996 to build its network, and expects to incur
an additional US$51 million to substantially complete the build-out (including
planned upgrade) by 1999.
 
                                       61
<PAGE>   66
 
  Digitalization
 
     In building its cellular network, the Company, along with the majority of
other Colombian cellular operators, selected TDMA technology and offered digital
cellular service from the commencement of operations. Colombian subscribers have
bought digital handsets in significant quantities. Because of the benefits of
digitalization, including additional revenue through the sale of
digital-specific value-added cellular services, reduced operating expenses and
greater network capacity, the Company has sought to increase the digitalization
of its subscriber base. Under the Concession, the Company's network is required
to have 10% digital voice channels by the third year of operation, 30% by the
fifth year and 50% by the eighth year. As of December 31, 1995, 35% of the voice
channels in the Company's network were programmed to be digital. Digitalization
represents one of the key marketing and technical variables in the Company's
ongoing network rollout plan.
 
  Equipment
 
     In building its cellular network, the Company has purchased cellular
equipment manufactured by Northern Telecom. Each of the Company's three
switching centers, located in Medellin, Cali and Pereira, respectively, is
equipped with a Super Node SE DMS-MTX. As of December 31, 1995, the Company's
cellular telecommunications network consisted of three cellular switching
centers, 65 base stations, 125 cells and four cellular repeaters. The network is
connected primarily by its own microwave transmission system provided by
Microwave Network Incorporated and Ericsson consisting of 70 microwave hops as
of December 31, 1995. Interconnection with local PSTNs occurs at six locations.
The Company has recently introduced a new software package which increases
network efficiency and provides new services. In addition, the Company maintains
a network management center in Medellin capable of monitoring the performance of
the switching centers in Medellin, Cali and Pereira, the radio base stations,
the microwave transmission links and the leased circuits provided by third
parties. The Company also had a supply agreement with Nortel for network
equipment which expired on April 15, 1996, although the Company intends, and is
currently in negotiations, to renew such agreement until December 31, 1999. The
supply agreement with Nortel contains provisions for guaranteed prices and
volume-related discounts. Although the Company is not bound by the provisions of
any supply agreement to purchase from a particular supplier, the compatibility
of any newly acquired equipment with the Company's existing equipment
effectively may limit the Company's options.
 
  Performance Monitoring
 
     The Company continuously monitors the network's performance to ensure that
cellular telecommunications service quality meets its published standards. These
standards are derived from the standards specified by the Colombian government
and are in line with high international standards.
 
     As of December 31, 1995, the Company was able to limit average dropped
calls (which reflects the ability of the system to sustain a call in progress)
to less than 3% and achieved an average call blockage rate (which reflects the
percentage of subscriber calls that are unable to access the network during peak
usage periods) between 1% to 2%.
 
COMPETITION
 
     The cellular telecommunications business in the Western Region is a
regulated duopoly. Each of the two operators awarded a concession for the
Western Region has the exclusive use for 10 years of a defined frequency band
within the region. Competition is principally based on price, network coverage
and technical quality, value-added cellular services, quality and responsiveness
of customer service. The Company's primary competitor, Cocelco, is the holder of
the other concession for the Western Region. Cocelco is controlled by
Organizacion Luis Carlos Sarmiento-Angulo Ltda., one of Colombia's largest
conglomerates, and counts Telefonica de Espana and Chile's CTC
telecommunications groups among its other shareholders. The Company may also
face additional cellular competition after 1999 when the Colombian government
may auction additional cellular concessions in the Western Region, depending on
the technical availability at that time.
 
                                       62
<PAGE>   67
 
     The Company also competes with traditional wireline telephone service
operators. Wireline density in Colombia as of December 31, 1994 is estimated by
the International Telecommunication Union at approximately 10 telephone lines
per 100 persons compared to a wireline density of approximately 60 lines per 100
persons in the United States. If substantial capital were to be invested in the
wireline telephone industry, resulting in increased wireline density and
improved service, certain of the Company's existing and potential subscribers
might shift to wireline service providers due to a number of factors, some of
which are price related. Empresas Publicas de Medellin ("EPM") has reported that
its wireline density in Medellin was 30 lines per 100 persons as of December 31,
1995 and is expected to increase to approximately 34 lines per 100 persons by
the year 2000. Empresas Municipales de Cali ("EMCALI"), on the other hand, has
reported that its wireline density in Cali was approximately 20 lines per 100
persons as of December 31, 1995, and is expected to increase to approximately 30
lines per 100 persons by the year 2000. Although competition in local wireline
services was authorized in 1990, first with the previous authorization from the
Ministry of Communications and in 1994 with free entrance into the market, no
new wireline operators have entered into the industry. The entrance of new
wireline operators would result in additional competition for the Company.
 
     The Company also competes with certain other wireless communication
services, such as mobile radio, paging or beeper services, which are widely used
in Colombia as a substitute for wireline services in order to improve
productivity and to address security concerns. These services have certain
disadvantages compared to cellular services because of factors such as lack of
coverage, lack of handset portability, lack of privacy, lower transmission
quality, network overloading and lack of customer service. These competing
wireless communication services are nevertheless considerably less expensive
than cellular services.
 
     Technological advances in the communications field, such as the possible
introduction of PCS and mobile satellite services, continue to occur and make it
difficult to predict the extent of additional future competition for cellular
systems. For example, several mobile satellite-based phone systems are planning
to initiate service by the year 2000. While such services may offer worldwide
coverage, significant technological and other hurdles need to be overcome before
such services may be offered in Colombia.
 
OPERATING AGREEMENTS
 
     Interconnection Agreements
 
     The Company has executed interconnection agreements with EPM, EMCALI,
Empresas Publicas de Manizales, Telearmenia and Empresas Publicas de Pereira,
the wireline companies serving such areas, and has letters of intent to enter
into interconnection agreements with other wireline operators, such as Telecom
and Empresas Departamentales de Antioquia ("EDA"). All these operators other
than Telecom are also shareholders of the Company. The terms of the
interconnection agreements include provisions for the number of connection
points, the method by which signals must be received and transmitted, fraud
control, billing, damage liability, and the assumption of responsibility for the
costs of interconnection. Under such interconnection agreements, which reflect
regulations issued by the TRC, wireline telephone companies charge cellular
operators a fee per minute when a cellular subscriber places a call to a
wireline subscriber. The Company believes the terms of the interconnection
agreements are similar to those of interconnection agreements executed by such
companies and Cocelco.
 
     Currently, negotiations are in process for leasing transmission
infrastructure with Empresa Cafetera Celular S.A. ("ECCEL S.A.") for the coffee
region and Empresa Regional de Telecomunicaciones del Valle S.A. ("ERT").
 
     Roaming Agreements
 
     Agreements for automatic roaming have been entered into with the other two
A Band concessionaires in Colombia, Comcel and Celcaribe. See "-- Industry
Cooperation". The Company also has roaming agreements that permit its
subscribers to use their cellular telephones in the United States, Canada and
Ecuador and subscribers can roam in Venezuela pursuant to a letter of intent. In
addition, the Company has understandings regarding the provision of roaming
services with certain countries in the Caribbean where
 
                                       63
<PAGE>   68
 
C&W is the mobile operator. See "-- Operations -- Services
Offered -- Supplemental Services -- International Roaming".
 
     Other Agreements
 
     The Company is currently in negotiations to regulate the billing process
for cellular calls from wireline telephone companies to the Company's cellular
customers with several wireline telephone operators such as ETB, Empresas
Publicas de Popayan, Empresas Publicas de Palmira and Empresas Publicas de
Buenaventura. These operators do not require interconnection agreements.
 
LEGAL PROCEEDINGS
 
  Medellin's Cellular Services Tax
 
     On August 17, 1994, the municipality of Medellin through Resolution No. 019
imposed a monthly tax (the "Cellular Services Tax") on cellular subscribers
placing calls through base stations located in Medellin. Subsequently, the Mayor
of Medellin, on January 23, 1995, regulated the billing and collection of the
Cellular Services Tax through Municipal Decree 1244 (the "Decree"), which
imposed upon the two cellular operators of the Western Region the obligation to,
in each of their billing systems, determine, bill, collect and transfer the
Cellular Services Tax. Both regulations have been judicially challenged on the
grounds of not being consistent and in conformity with current higher ranking
law. Medellin's tax authorities through Resolution No. 005 and Resolution No.
006, issued on March 6, 1996 and May 17, 1996, respectively, determined that
Occel's transfer obligation under the Decree for the period through March 30,
1996, together with interest through May 17, 1996, is Ps 565 million
(US$587,236). The Company appealed this determination on March 14, 1996 and June
11, 1996, and a decision is still pending. Occel has not collected the Cellular
Services Tax from its customers because it believes that the tax is illegal and
that the challenges against Resolution No. 019 and the Decree will be successful
and, consequently, Resolution No. 005 and Resolution No. 006 will not be upheld.
In the event of unfavorable decisions in the referred cases, the Company
believes that it would be able to collect from its customers a portion of the
Cellular Services Tax. See "Risk Factors -- Tax Litigation".
 
  Other
 
     The Company is involved in other litigation from time to time in the
ordinary course of business. In management's opinion, the litigation in which
the Company is currently involved, individually and in the aggregate, is not
material to the Company's financial condition or results of operations.
 
EMPLOYEES
 
     As of December 31, 1995, the Company had 490 permanent full-time employees
and an additional 82 temporary full-time employees. None of the Company's
employees are unionized. The Company believes its employee relations are good.
 
PROPERTIES
 
     The Company has offices in Medellin, Cali, Pereira, Manizales and Armenia.
The Company owns the building in Medellin where its headquarters are located
(approximately 3,000 square meters) and leases approximately 2,500 square meters
of office space in Cali, Pereira, Manizales, Armenia, Rionegro, Cartago and
Apartado.
 
     The Company also owns or leases the sites where its cellular network
equipment is installed. As of December 31, 1995, the Company had 65 sites, 18 of
which were owned by the Company and the remainder of which were leased. Most of
these leases do not expire prior to 2000. In addition, the Company leases nine
and owns one of the sites where its cellular repeater (including its microwave
repeater) stations are located.

                                   REGULATION
 
  Regulatory Authorities and Legislation
 
     The Ministry of Communications and the Telecommunications Regulation
Commission ("TRC") are responsible for the regulation and oversight of the
telecommunications sector, including cellular operations. The Ministry of
Communications, which granted the cellular concessions in 1994, supervises and
audits the performance of the concessionaires' legal and contractual
obligations, in particular those related to the technical standards established
in the bid conditions and to the concessionaires' duty to answer their
subscribers' questions and complaints. The Ministry of Communications also has
general authority to issue regulations for cellular operations, subject to their
being in accordance with applicable law. The TRC is chaired by the Minister of
Communications and its other members are the Director of the National Planning
Department (Departamento Nacional de Planeacion) and three full-time experts
appointed by the President of Colombia. The TRC, which has jurisdiction over the
pricing of cellular services, has decided that tariffs be freely set by the
cellular operators with prior notice to the TRC and their subscribers. The TRC
is also charged with issuing regulations intended to promote free competition in
the cellular industry. In addition, the TRC regulates the pricing aspects of the
relationship between cellular and wireline operators, including interconnection
terms and tariffs.
 
     The Company's activities are also subject to the oversight of the Colombian
Superintendency of Industry and Commerce (Superintendencia de Industria y
Comercio) ("SIC"), which is empowered to enforce anti-trust regulations, protect
free competition in the marketplace and protect consumer rights on a
case-by-case basis.
 
     Finally, the Superintendency of Corporations (Superintendencia de
Sociedades) is entitled by Colombian Commercial Law to exercise legal control
over certain activities of the Company such as shares issuance, bonds placement
and equity reductions.
 
     The operations of the Company as a cellular operator are principally
governed by Law 37 of 1993 ("Law 37") and Decree 741 of 1993 ("Decree 741") and
the terms and conditions of the Concession and related documents. Law 37 sets
forth the basic framework for the introduction of cellular telecommunications
services in Colombia. Law 37 established a public bidding process open to
private-sector, public-sector and mixed-economy companies. Mixed-economy
companies have both public-sector and private-sector shareholders, engage in
commercial business activities and are created pursuant to special legislation.
For purposes of the bidding process, the country was divided into three regions,
(i) the Eastern Region, (ii) the Western Region, and (iii) the Atlantic Region.
Each Region has two competing operators: (i) one public-sector or mixed-economy
company and (ii) one wholly private-sector company. This effectively resulted in
a cellular duopoly similar to that which characterizes the United States, Canada
and most Latin American countries. Law 37 also authorized foreign investment in
certain areas of the telecommunications industry, including cellular operations.
Subsequently, Decree 741 established detailed rules for the bidding process and
developed provisions contained in Law 37 regarding matters such as the corporate
structure of cellular operators, the assignment of frequencies, the concession
agreements to be entered into between the winner of the bidding process and the
Ministry of Communications and the rules for interconnection between wireline
and cellular operators. Cellular operators are also subject to Decree 1900 of
1990 ("Decree 1900"), which regulates telecommunications services in general, to
the extent that Decree 1900 does not contradict the terms of Law 37.
 
  Terms of the Concession
 
     The Concession consists of the right to establish and develop a cellular
telecommunications business in the Western Region over a ten-year period in
exchange for a one-time Concession fee combined with quarterly royalty payments
to the Ministry of Communications for the use of cellular frequencies. The
Company was awarded the Concession in a competitive bidding process, based upon
not only the price offered by the Company, but also its technical capabilities
and operational capacity, the mobile cellular experience of its affiliates, and
its financial and planning capability. The Concession's term is 10 years
commencing March 28,
 
                                       65
<PAGE>   70
 
1994. The purchase price for the Concession was Ps 123.1 billion (actual Pesos)
(US$148.5 million at the April 13, 1994 Representative Market Rate), of which Ps
105.8 billion (US$127.7 million at the April 13, 1994 Representative Market
Rate) represented the actual fee paid for the Concession, while the remaining Ps
17.3 billion (actual Pesos) (US$20.8 million at the April 13, 1994
Representative Market Rate) represented the amount contributed by the Company to
a special expansion plan for municipalities with unsatisfied basic needs. In
addition, the Company makes a quarterly royalty payment to the Ministry of
Communications for the right to use its assigned frequencies in an amount equal
to 5% of the sum of activation fees, monthly fixed fees, airtime charges,
interconnection fees and supplementary services, minus interconnection costs
paid by the Company to other telecommunications operators.
 
     The Concession may be renewed for an additional 10-year term provided that
the Company has met the terms of the Concession and neither the Ministry of
Communications nor the Company has expressed an intention not to renew during
the Concession's eighth year. If renewed, an extension of the concession
agreement will be executed during the first year of renewal, containing the
economic conditions agreed upon by the licensees and the government.
 
     The Concession requires the Company to guarantee the performance of its
obligations thereunder and the payment of any liquidated damages or fines (as
described below) by obtaining a performance bond from a Colombian insurance
company or bank in an amount equal to approximately Ps 11.4 billion (US$10.9
million) (the "Performance Bond"). The Company has also obtained third party
liability insurance for Ps 1.1 billion (US$1.1 million) as required by the
Concession. Finally, the Company obtained a renewal bond of approximately Ps 1.0
billion (US$1.0 million) to support its obligation to maintain in force the
Performance Bond and the third party liability insurance policy.
 
     The Company and Cocelco, the Company's Western Region competitor, will
operate their cellular networks with no additional competition for five years.
After March 1999, the fifth anniversary of the Concession, the Ministry of
Communications may grant additional concessions for cellular telecommunications
services or other competing services in each of the Regions, depending on
technical availability at that time.
 
     The ability to provide national roaming (between concessioned cellular
telecommunications networks) is required by the Concession. Cellular companies
are also required to enter into interconnection agreements with wireline
telephone companies.
 
     The terms of the Concession and applicable Colombian law prohibit the
Company from assigning the Concession, and the shareholders from transferring
any shares of capital stock of the Company, for a period of three years.
Thereafter, assignment of the Concession is permitted only with the prior
approval of the Ministry of Communications, and shares of capital stock of the
Company may be transferred pursuant to the Company's Bylaws.
 
     The terms of the Concession bid required the Company to submit a detailed
timetable of its expansion plan, identifying the key cities, highways and other
areas to be covered by its network in the Western Region. During the second half
of the fifth year of the Concession, the Ministry of Communications, together
with the Company, will review the expansion plan. During this review, the
parties will determine if adjustments to the timetable are needed as a result of
developments in Colombia during the intervening years.
 
     Colombia is one of three Latin American countries which mandate "calling
party pays" policy. Contrary to North American practice, where a cellular user
generally pays for both outgoing and incoming calls, the "calling party pays"
policy requires the originator of the call to pay for the total cost of the
call. This policy reduces the cost of cellular services to cellular users. The
Company believes that the policy of calling party pays stimulates additional
usage by effectively spreading the cost of cellular service among cellular phone
subscribers and wireline phone subscribers.
 
     The Concession allows the Company to provide certain services not typically
permitted to be offered by cellular operators in North America. Unlike the North
American model, the Company is permitted to deliver calls anywhere in the
Western Region when it has the capability to do so, without routing such calls
through a long distance carrier and then sharing the resulting revenue. The
Company may also deliver calls to any
 
                                       66
<PAGE>   71
 
Region provided that it has a reciprocal agreement with an operator in such
Region. In addition, the bid conditions contemplated the possibility of
providing cellular service to subscribers using fixed equipment rather than
mobile handsets. The Company is thus offering fixed cellular services under the
trade name "Fijovoz". The Company has also successfully marketed the product
"Beepervoz" which enables the user to have a cellular phone only for incoming
calls, outgoing calls only to the Company's *911 emergency service and
optionally, voice mail (for an additional charge).
 
     Service Standards.  The Company files a written quarterly report on
technical performance indicators designed by the Ministry of Communications to
ensure that the service provided to subscribers is consistent with the
concession standards. Performance indicators include network congestion levels,
percentage of dropped calls, cell availability and microwave availability. The
Company also provides general network indicators such as details of cellular
traffic flows, cell site traffic loads and network status updates. Additionally,
the Ministry of Communications requires from all cellular companies to provide a
quarterly report on adjusted gross revenues for the period in order to liquidate
the 5% amount due to the Ministry.
 
     Digital Technology Requirements.  In its bidding specifications, the
Colombian government required the initial use of analog AMPS technology or
AMPS-compatible technology in order to ensure compatibility with cellular
systems in neighboring countries and in North America. There are two types of
digital multiplexing technologies: (i) TDMA, which is currently commercially
available and is being deployed in Colombia and in North America and (ii) CDMA,
which is under development. Pursuant to the Concession, on March 28, 1996 (the
second anniversary thereof), the Ministry of Communications decided that each
cellular operator is free to choose between TDMA and CDMA. Under the terms of
the Concession, the Company's network is required to have 10% digital voice
channels by the third year of operation, 30% by the fifth year and 50% by the
eighth year. As of December 31, 1995, 35% of the voice channels in the Company's
network were programmed to be digital.
 
     Social Sector Participation.  Colombian law requires that concessionaires
operating cellular telecommunications systems authorize for issuance 10% of
their total share capital (on a fully-diluted basis) to organizations belonging
to the "Social Solidarity Sector", of the economy consisting of unions,
foundations, non-profit or charitable corporations, employees' funds, credit
unions and savings cooperatives. The issuance of shares is to be made at the
option of the Social Solidarity Sector entities and may be exercised at any time
prior to March 28, 1998. The exercise price of this option would be at fair
market value. The Ministry of Communications has not issued complete regulations
for the implementation of this requirement.
 
     Restriction on Transfer of Shares by Certain Shareholders.  Pursuant to the
terms of the Concession, the shareholders of the Company are subject to
restrictions in the transfer of shares of common stock. The Concession requires
that the aggregate percentage of the capital stock of the Company held by
shareholders registered as "operators" and "traders" during the license
auctioning process remain constant for the term of the Concession. Consequently,
absent the Ministry of Telecommunications' approval, no transfers of shares of
the Company by those shareholders registered as "operators" or "traders",
respectively, are allowed if as a result such aggregate percentages would vary.
 
     Fines.  The Ministry of Communications may impose fines for noncompliance
with the terms and conditions of the Concession. The fine for nonperformance
depends on the gravity of the offense, the damage done and any recurrence and
can reach up to Ps 142 million (US$143,800) upon the occurrence of any event of
default. Breaches that may subject the Company to fines include: (i)
nonperformance or delay in the performance of the timetable established for the
expansion of the cellular services after the Ministry of Communications has
formally notified the Company that compliance is required, except where non-
performance or delays are caused by force majeure or by acts of God; (ii) the
installation or connection of equipment with wireline networks that does not
meet interconnection standards and plans, or damages the wireline network as a
result of using unauthorized connections or installations, without prejudice to
compensation due to injured parties; (iii) the Company unjustifiably fails to
provide the information and cooperation required by the Ministry of
Communications; and (iv) the Company fails to perform its obligations under the
Concession and applicable regulations that, in the Ministry of Communications'
opinion, do not justify the termination of the Concession.

     Termination upon Default in Performance.  Defaults which directly and
materially impair the ability of the Company to perform the services under the
Concession constitute grounds for its termination by the Ministry of
Communications. In addition, certain specific events are defined as constituting
grounds for such termination, including (i) providing false information at the
time of submission of the bid or prequalification document; (ii) assigning of
the Concession without the Ministry of Communications' approval; (iii)
suspending service without the Ministry of Communications' approval or without a
justifying cause; (iv) defaulting on required payments to the Ministry of
Communications; (v) providing false information which affects the calculation of
required payments to the Ministry of Communications; (vi) transferring shares
during the first three years of the concession and (vii) anti-competitive
behaviors. In the event of termination for default in performance, the Company
would not be entitled to compensation for loss of the Concession for the
remaining term. In addition, the Ministry of Communications would be entitled to
reversion of the assets directly related to the Concession and to payment of the
Performance Bond. The Ministry of Communications may also seek payment from the
Company for any damages suffered in excess of the amount covered by the
Performance Bond.
 
     Reversion of Assets.  At the end of the Concession's term, the Company's
assets directly related to the Concession are to revert to the Ministry of
Communications without compensation. During the concession bidding process, most
bidders expressed their concern regarding the extent of any such reversion. The
bidders, including the Company, argued that the interpretation of this clause
should be limited to the cellular frequencies assigned to each concessionaire
which are the basis for the concessions and for which each concessionaire pays a
quarterly fee. There can be no assurance that the concessionaires will be
successful in persuading the Ministry of Communications to limit this
interpretation to cellular frequencies. However, as a support to the Company's
interpretation, under recently issued regulations enacted in relation to the
long distance bidding process that will take place in 1996, reversion of assets
will not apply to such concessions. Although these rules apply only to long
distance service concessions, the Company believes they may establish the
government's policy on the interpretation of the reversion of assets issue. See
"Risk Factors -- Regulatory and Concession Matters".
 
     Unilateral Interpretation, Modification and Termination of Government
Contracts.  The Concession is subject to unilateral interpretation, modification
and termination under Law 80 of 1993 ("Law 80"), which is applicable to
Colombian government contracts. Pursuant to Law 80, in the event that a dispute
arises as to the interpretation of the Concession between the Ministry of
Communications and the Company, and an agreement cannot be reached between the
parties, the Ministry of Communications has the right to unilaterally interpret
the Concession if necessary in order to prevent a suspension of cellular service
to the public. If during the performance of the Concession, the need arises to
modify it in order to avoid a suspension of the public service contemplated
therein, and agreement cannot be reached between the parties, then the
government may unilaterally modify the relevant provisions. In addition, the
Ministry of Communications may unilaterally terminate the Concession in the
event that public service or public policy so requires, or if the Company
becomes legally unable (because of bankruptcy or dissolution of the Company or
attachment of a substantial portion of its assets which has a material adverse
effect on the Company's ability to render its cellular services) of performing
its obligations under the Concession. In the event of unilateral interpretation,
modification or termination, based on circumstances not attributable to the
Company, the Company may judicially challenge such decision and demand fair
compensation from the Ministry of Communications. In addition, the Ministry of
Communications may, without compensation, terminate the concession for certain
events of default under the Concession; in the event of such termination, the
Ministry of Communications would also be entitled to a payment by the Company in
the amount of the performance bond posted by the Company under the Concession.
See "Risk Factors -- Regulatory and Concession Matters".
 
     Arbitration.  Except for those disputes discussed above under
"-- Termination Upon Default in Performance" and "-- Unilateral Interpretation,
Modification and Termination of Government Contracts", any other disputes
related to the granting, execution, development or termination and liquidation
of the Concession, which cannot be directly resolved between the Company and the
Ministry of Communications, must be submitted to a three-member arbitration
panel which will decide in accordance with Colombian law.

                   CERTAIN TRANSACTIONS WITH RELATED PARTIES
 
INTERCONNECTION AGREEMENTS
 
     The Company has entered into interconnection agreements with wireline
operators which include EPM, EMCALI, Empresas Publicas de Manizales, Telearmenia
and Empresas Publicas de Pereira and has executed a letter of intent to enter
into an interconnection agreement with Empresas Departamentales de Antioquia and
Telecom. All of these wireline operators beneficially own capital stock of the
Company. The terms of the interconnection agreements include provisions for,
among other things, the number of connection points, the method by which signals
must be received and transmitted, and the assumption of responsibility for the
cost of interconnection. The Company believes that these interconnection
agreements contain terms substantially similar to the terms of the
interconnection agreements between Cocelco and such wireline operators. In
addition, the Company is currently negotiating lease agreements with ECCEL S.A.,
which owns 9.75% of the capital stock of the Company, and ERT (a shareholder of
Empresa Regional de Telecomunicaciones Celulares S.A.), which beneficially owns
approximately 3.84% of the capital stock of the Company, for the leasing of
transmission capacity.
 
AGREEMENTS WITH CABLE AND WIRELESS PLC
 
     The Company has had in the past several consulting arrangements with C&W
for the provision of technical, commercial, financial, marketing and billing
support. Although currently the Company does not have any consulting arrangement
with C&W, the latter continues to provide advice with respect to technical,
financial and equipment purchasing matters. As of December 31, 1995, the Company
had paid C&W an aggregate amount of approximately, Ps2.1 billion (US$2.0
million) for services rendered in the last three years.
 
                      DESCRIPTION OF COMPANY INDEBTEDNESS
 
BANK FACILITY
 
     The description set forth below does not purport to be complete and is
qualified in its entirety by reference to the definitive documentation for the
Credit Agreement entered into by the Company, ING Baring (U.S.) Securities, Inc.
and Merrill Lynch & Co., as arrangers (the "Arrangers"), ING Bank, N.V. and ING
(U.S.) Capital Corporation, as administrative and collateral agents (the
"Agents"), and the financial institutions party thereto (the "Credit
Agreement"), which is filed as exhibits to the Registration Statement of which
this Prospectus is a part.
 
     The Agents and the Arrangers have provided the Company with a term loan in
an aggregate principal amount of U.S.$80.0 million (the "Term Loan"). The
principal amount of the Term Loan is scheduled to be repaid in four semiannual
amortizations, each equal to 10% of the principal amount thereof, commencing on
the third anniversary of the closing date under the Credit Agreement, with the
remaining 60% of the principal amount of the Term Loan due five years and one
day after disbursement thereof. The interest rate per annum applicable to the
Bank Facility is the sum of the Applicable Margin plus the applicable Eurodollar
Rate. Such sum was equal to 9.3125% as of June 30, 1996. The Applicable Margin
shall be 3.75%; provided, however, that if the Company satisfies certain
leverage ratios, the Applicable Margin may be reduced by as much as 1%.
 
     The Company is required to make mandatory prepayments of the Term Loan in
amounts, at times and subject to certain exceptions, (i) in respect of 100% of
the cash proceeds of the issuance of equity in the Borrower in excess of
U.S.$30.0 million or the issuance or incurrence of indebtedness not permitted
pursuant to the Credit Agreement and (ii) in respect of 50% of the excess cash
flow of the Company.
 
     The obligations of the Company under the Credit Agreement are secured by,
among other things, (i) all of the Company's receivables originated from the
provision of cellular communications and roaming and interconnection services,
(ii) the pledge of 99.99% (as of the date thereof) of the Company's outstanding
 
                                       73
<PAGE>   78
 
common stock and (iii) the pledge of the Concession to operate its business,
provided that the Lenders may not exercise any remedies thereunder prior to
March 28, 1997.
 
     For the period described above until the restriction on the right of the
Lenders to exercise their remedies under the pledge of the Concession expires,
the Indenture will provide that should the Company enter into a bankruptcy
reorganization (concordato) or liquidation under the laws of Colombia during
such period, the Trustee will turn over to the Agents for the lenders under the
Bank Facility all amounts that constitute proceeds of the Concession received
pursuant to a bankruptcy reorganization (concordato)or liquidation until all the
claims under the Bank Facility are satisfied.
 
     The Credit Agreement contains a number of significant covenants that, among
other things, restrict the ability of the Company to create liens on assets, pay
dividends, incur additional indebtedness, make investments or advances, engage
in mergers or consolidations and otherwise restrict corporate activities. In
addition, under the Credit Agreement, the Company is required to comply with
specified financial ratios and tests, including quarterly recurring revenue,
fixed charge coverage, interest coverage and maximum leverage.
 
     The Credit Agreement also contains provisions that limit the Company's
ability to modify the Indenture relating to the Notes and to refinance the
Notes.
 
OTHER INDEBTEDNESS
 
     As of June 30, 1996, the Company also had Ps 36.6 billion (US$34.2 million)
of aggregate payments (without discount to present value) relating to leases and
US$1.8 million of letters of credit.
 
                            DESCRIPTION OF THE NOTES
 
     The Old Notes were issued and the New Notes offered hereby will be issued
under an indenture dated as of June 1, 1996 (the "Indenture") between the
Company, as issuer, and The Bank of New York, as trustee (the "Trustee"), a copy
of which is filed as an exhibit to the Registration Statement of which this
Prospectus is a part. The Indenture is subject to and governed by the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following
summary of the material provisions of the Indenture does not purport to be
complete and is subject to, and qualified in its entirety by reference to, the
provisions of the Indenture, including the definitions of certain terms
contained therein and those terms made part of the Indenture by reference to the
Trust Indenture Act. For definitions of certain capitalized terms used in the
following summary, see "-- Certain Definitions".
 
GENERAL
 
     The Notes will mature on March 15, 2004, will be limited to US$190,745,000
aggregate principal amount at maturity and will be general senior unsecured
obligations of the Company. Based on the issue price thereof, the yield to
maturity of the Notes is 14% per annum (computed on a semiannual bond equivalent
basis) calculated from June 7, 1996.
 
     The Old Notes have been offered at a substantial discount from their
principal amount at maturity. Cash interest will not accrue on the Notes prior
to March 15, 2001. Thereafter, cash interest on the Notes will be payable at the
applicable rate set forth on the front cover of this Prospectus, semiannually in
arrears on each March 15 and September 15, commencing September 15, 2001, until
the principal thereof is paid or duly provided for, to the Person in whose name
the Note (or any predecessor Note) is registered at the close of business on the
March 1 or September 1 next preceding such interest payment date. Cash interest
will accrue from the most recent interest payment date to which interest has
been paid or, if no interest has been paid, from March 15, 2001. Cash interest
will be computed on the basis of a 360-day year of twelve 30-day months.
 
     Principal of, premium, if any, and interest on the Notes will be payable,
and the Notes will be exchangeable and transferable, at the office or agency of
the Company in The City of New York maintained for such purposes (which
initially will be the Trustee); provided, however, that, at the option of the
Company, interest may be paid by check mailed to the address of the Person
entitled thereto as such address shall appear on the security register.
(Sections 301, 305 and 1002) The Old Notes have been and the New Notes will be
 
                                       74
<PAGE>   79
 
issued only in registered form without coupons and only in denominations of
US$1,000 and any integral multiple thereof. (Section 302) No service charge will
be made for any registration of transfer or exchange or redemption of Notes, but
the Company may require payment in certain circumstances of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith. (Section 305)
 
ADDITIONAL AMOUNTS
 
     The Notes provide that any and all payments thereunder will be made free
and clear of and without deduction for or on account of any and all present or
future taxes, levies, imposts, deductions, charges or withholdings and all
liabilities with respect thereto imposed by Colombia or any political
subdivision thereof excluding any taxes, levies, imposts, deductions, charges or
withholdings and all liabilities with respect thereto (i) resulting from the
holder of a Note having some connection with Colombia or any political
subdivision thereof other than the mere holding of or enforcement of or receipt
of any payment with respect to such Note, (ii) the payment of which may be
avoided by the holder of a Note complying with any certification, declaration or
other reporting requirement concerning the nationality, residence, identity or
connection with any taxing authority of such holder as the beneficial owner of
such Note, (iii) that would not have been imposed but for the presentation
(where presentation is required) of such Note for payment more than 30 days
after the date such payment became due and payable or was duly provided for,
whichever occurs later, (iv) in the nature of estate, inheritance, gift, sale,
transfer, personal property or similar taxes, or (v) imposed on or with respect
to any payment by the Company to the holder of a Note if such holder is a
fiduciary or partnership or person other than the sole beneficial owner of such
payment to the extent such tax, levy, impost, deduction, charge or withholding
would not have been imposed on a beneficiary or settlor with respect to such
fiduciary, member of such partnership or the beneficial owner of such payment
had such beneficiary, settlor, member or beneficial owner been the holder of
such Note (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being referred to collectively or individually as
"Colombian Withholding Taxes"). If the Company is required by law to deduct any
Colombian Withholding Taxes from or in respect of any sum payable under a Note,
the sum payable thereunder shall be increased by the amount necessary so that
after making all required deductions the holder of a Note will receive an amount
equal to the sum it would have received had no such deductions been made (such
additional amounts to be paid by the Company in accordance with the foregoing
being "Additional Amounts").
 
     At least 30 calendar days prior to each date on which any payment under or
with respect to the Notes is due and payable, if the Company will be obligated
to pay Additional Amounts with respect to such payment, the Company will deliver
to the Trustee an Officers' Certificate stating the fact that such Additional
Amounts will be payable and the amounts so payable and will set forth such other
information necessary to enable the Trustee to pay such Additional Amounts to
holders of Notes on the payment date. Whenever in the Indenture or in this
"Description of the Notes" there is mentioned, in any context, the payment of
principal, interest, if any, or any other amount payable, under or with respect
to any Note, such mention shall be deemed to include mention of the payment of
Additional Amounts to the extent that, in such context, Additional Amounts are,
were or would be payable in respect thereof.
 
RANKING
 
     The Notes are senior unsecured obligations of the Company, and the
Indebtedness evidenced by the Notes ranks pari passu in right of payment with
all other existing and future unsubordinated obligations of the Company (other
than obligations preferred by statute or by operation of law), except to the
extent that the provisions of the Indenture require the Trustee, during the
period from the Issue Date until the restriction on the right of the Lenders to
exercise their remedies under the pledge of the Concession expires, to turn over
to the collateral agents for the lenders under the Bank Facility all amounts
that constitute proceeds of the Concession received pursuant to a bankruptcy
reorganization (concordato) or liquidation of the Company until all claims under
the Bank Facility are satisfied, and senior in right of payment to all existing
and future Indebtedness of the Company expressly subordinated in right of
payment to any other Indebtedness of the Company. The Company currently has no
subordinated Indebtedness outstanding. The Notes, however, are effectively
subordinated to senior secured obligations of the Company with respect to the
assets of the
 
                                       75
<PAGE>   80
 
Company securing such obligations, including Indebtedness under the Bank
Facility, which are secured by, among other things, (i) all of the Company's
receivables originated from the provision of cellular communications and roaming
and interconnection services and (ii) when such pledge is permitted by law, but
not earlier than May 1, 1997, the Concession to operate its business. The
Indebtedness under the Bank Facility is also secured by a pledge of 99.99% of
the Company's outstanding common stock. See "Description of Company
Indebtedness -- Bank Facility". As of June 30, 1996, Indebtedness of the Company
was approximately US$181.8 million, of which US$80.0 million was senior secured
Indebtedness and US$101.8 million was senior unsecured Indebtedness. Subject to
certain limitations, the Company and any Restricted Subsidiary may incur
additional Indebtedness, including secured Indebtedness, in the future.
 
MANDATORY REDEMPTION
 
     The Company will redeem 50% of the original aggregate principal amount at
maturity of the Notes on March 15, 2003 at 100% of the principal amount thereof,
together with accrued and unpaid interest to the redemption date on a pro rata
basis from Persons in whose name the Notes (or any predecessor Note) are
registered at the close of business on March 1, 2003. Notice of redemption will
be mailed, first-class postage prepaid, at least 30 but not more than 60 days
before the redemption date to each holder of Notes to be redeemed at its
registered address. On and after the redemption date, interest will cease to
accrue on Notes or portions thereof called for redemption and accepted for
payment.
 
OPTIONAL REDEMPTION
 
     Redemption at the Option of the Company.  The Notes are redeemable at the
option of the Company, as a whole or from time to time in part, on not less than
30 nor more than 60 days' prior notice (i) at 100% of the principal amount
thereof if redeemed prior to September 15, 2000, (ii) 107.5% of the Accreted
Value thereof if redeemed during the six months beginning September 15, 2000 and
(iii) at the redemption prices (expressed as percentages of principal amount)

     In addition, at any time prior to March 15, 1999 the Company may redeem up
to 33% of the original aggregate principal amount at maturity of the Notes
within 45 days of one or more Public Equity Offerings with the net proceeds of
such offering at a redemption price equal to 114% of the Accreted Value thereof,
provided that no less than 67% of the original aggregate principal amount at
maturity of the Notes remains outstanding.
 
     For certain restrictions on the Company's ability to redeem the Notes, see
"-- Prepayment Events Prior to First Anniversary", "-- Prepayment Events Prior
to Third Anniversary" and "Foreign Investment and Exchange Controls".
 
     Redemption at the Option of the Company for Changes in Colombian
Withholding Tax.  The Notes are redeemable at the option of the Company, as a
whole, but not in part, at any time upon not less than 30 nor more than 60 days'
prior notice at 100% of the Accreted Value on the date of redemption, together
with accrued interest, if any, to the date of redemption, in the event the
Company has become or would be obligated to pay, on any date on which any amount
would be payable with respect to the Notes, any Additional Amounts as a result
of a change in the laws (including any regulations promulgated thereunder) of
Colombia (or any political subdivision or taxing authority thereof or therein),
or any change in any official position regarding the application or
interpretation of such laws or regulations, which change is announced or becomes
effective on or after the Issue Date (a "Tax Redemption").

     For certain restrictions on the Company's ability to redeem the Notes, see
"-- Prepayment Events Prior to First Anniversary", "-- Prepayment Events Prior
to Third Anniversary" and "Foreign Investment and Exchange Controls in
Colombia".
 
     Selection and Notice.  If less than all the Notes are to be redeemed, the
particular Notes to be redeemed will be selected not more than 60 days prior to
the redemption date by the Trustee by such method as the Trustee deems fair and
appropriate; provided, however, that no such partial redemption will reduce the
principal amount of a Note not redeemed to less than US$1,000. Notice of
redemption will be mailed, first-class postage prepaid, at least 30 but not more
than 60 days before the redemption date to each holder of Notes to be redeemed
at its registered address. On and after the redemption date, interest will cease
to accrue on Notes or portions thereof called for redemption and accepted for
payment. (Sections 1104, 1105, 1107 and 1108).
 
     Prepayment Events Prior to First Anniversary.  Colombian law currently
prohibits the prepayment of the Notes within one year of their issuance, whether
by redemption, repurchase, acceleration or otherwise. Accordingly, the Company
will not be able to effect an optional redemption, including a Tax Redemption,
during such period as long as such limitation is in effect. In addition, as long
as such limitation under Colombian law is in effect, in the event any mandatory
redemption, repurchase, acceleration or other event requiring repayment occurs
on or prior to the first anniversary of the Issue Date, in lieu of such
redemption, repurchase, acceleration or other prepayment, the Company will be
required to deposit with the Trustee cash and/or United States Government
Obligations in an amount (without taking into account the payment of interest
thereon) sufficient to make such prepayment with respect to the Notes on the
first Business Day after the first anniversary of the Issue Date ("First
Anniversary Date") at a price which the Company would have had to pay with
respect to such a prepayment occurring on the First Anniversary Date; provided,
however, that in the event of an offer to purchase described under "Certain
Covenants -- Purchase of Notes upon a Change of Control," the Company would have
to deposit with the Trustee an amount (without taking into account the payment
of interest thereon) sufficient to repurchase all of the Notes. Any funds
deposited with the Trustee (together with any additional funds provided by the
Company, if necessary) will be used by the Trustee to make the required
prepayment on the Notes on the First Anniversary Date. If the Company shall have
made the deposit with the Trustee as described in this paragraph, it will not be
in default of its obligations to redeem or repurchase the Notes prior to the day
on which the Notes are to be redeemed or repurchased as provided in the
preceding sentence.
 
     Prepayment Events Prior to Third Anniversary.  Colombian law currently
imposes certain deposit requirements on the Company upon a redemption,
repurchase, acceleration or other event requiring repayment on or prior to the
third anniversary of the Issue Date. See "Foreign Investment and Exchange
Controls in Colombia". Accordingly, in the event of an optional redemption,
including a Tax Redemption, a repurchase described under "Certain
Covenants -- Purchase of Notes upon a Change of Control" or any prepayment of
Notes upon acceleration on or prior to the third anniversary of the Issue Date
and after the one-year period described in the preceding paragraph, the Company
must comply with applicable law, including making the deposit required by the
Central Bank as described under "Foreign Investment and Exchange Controls in
Colombia" should such requirement then exist, prior to such redemption, purchase
or acceleration of the Notes. In addition, the Indenture provides that in the
event of any Excess Proceeds Offer from any Asset Sale on or prior to the third
anniversary of the Issue Date in which more than 40% of the aggregate principal
amount at maturity of the Notes (or such lesser amount that, when added to the
Notes previously redeemed or purchased, would exceed 40% of the aggregate
principal amount at maturity of the Notes) have been tendered for purchase, the
Company may (i) make the deposit required by the Central Bank as described under
"Foreign Investment and Exchange Controls in Colombia" and thereafter complete
the repurchase pursuant to the Excess Proceeds Offer or (ii) purchase pro rata
40% of the aggregate principal amount at maturity of the Notes (or such lesser
amount that would result, together with any prior redemption or purchase, in an
aggregate of 40% of the aggregate principal amount at maturity of the Notes
having been redeemed or purchased) and in lieu of the redemption of the
remainder of such tendered Notes, deposit with the Trustee cash or United States
Government Obligations in an amount (without taking into account the payment of
interest thereon) sufficient to purchase such remaining Notes on the first
Business Day after the
 
                                       77
<PAGE>   82
 
third anniversary of the Issue Date at a purchase price equal to the Accreted
Value of the Notes together with accrued interest to the date of purchase. Any
funds deposited with the Trustee (together with any additional funds provided by
the Company, if necessary) will be used by the Trustee to make the required
prepayment on the Notes on the first Business Day after the third anniversary of
the Issue Date. If the Company shall have made the deposit with the Trustee as
described in this paragraph, it will not be in default of its obligations to
redeem or repurchase the Notes prior to the day on which the Notes are to be
redeemed or repurchased as provided in the preceding sentence.

     Limitation on Indebtedness.  (a) The Company will not create, issue,

     the proposed Restricted Payment (the amount of any such Restricted Payment,
     if other than cash, as determined by the Board of Directors of the Company,
     whose determination shall be conclusive and evidenced by a Board
     Resolution) (1) no Default or Event of Default shall have occurred and be
     continuing, (2) the Company could incur at least US$1.00 of additional
     Indebtedness (other than Permitted Indebtedness) pursuant to the
     "Limitation on Indebtedness" covenant and (3) the aggregate amount of all
     Restricted Payments declared or made after the Issue Date shall not exceed
     the sum of:
 
          (A) the remainder of (x) cumulative Consolidated Cash Flow of the
     Company during the period (taken as a single accounting period) beginning
     on the first day of the fiscal quarter of the Company beginning after the
     Issue Date and ending on the last day of the last full fiscal quarter
     immediately preceding the date of such Restricted Payment for which
     quarterly or annual financial statements of the
 
                                       78
<PAGE>   83
 
     Company are available minus (y) the product of 1.75 times cumulative

     Company from the issuance or sale (other than to any Restricted Subsidiary)
     of debt securities or Redeemable Capital Stock that have been converted

          (D) to the extent not otherwise included in the Consolidated Cash Flow
     of the Company, an amount equal to the sum of (i) the net reduction in
     Investments in any Person (other than the Permitted Investments) resulting
     from the payment in cash of dividends, repayments of loans or advances or
     other transfers of assets, in each case to the Company or any Restricted
     Subsidiary after the Issue Date from such Person and (ii) the portion
     (proportionate to the Company's equity interest in such Subsidiary) of the
     fair market value of the net assets of any Unrestricted Subsidiary at the
     time such Unrestricted Subsidiary is designated a Restricted Subsidiary;
     provided, however, that in the case of (i) or (ii) above the foregoing sum
     shall not exceed the amount of Investments previously made (and treated as
     a Restricted Payment) by the Company or any Restricted Subsidiary in such
     Person or Unrestricted Subsidiary, plus
 
          (E) US$2.5 million.
 
     (b) Notwithstanding paragraph (a) above, the Company and any Restricted
Subsidiary may take the following actions so long as (with respect to clauses
(ii), (iii), (iv) and (v) below) no Default or Event of Default shall have
occurred and be continuing:
 
          (i) the payment of any dividend within 60 days after the date of
     declaration thereof, if at such date of declaration the payment of such
     dividend would have complied with the provisions of paragraph (a) above
     (such payment will be deemed to have been paid on such date of declaration
     for purposes of the calculation required by paragraph (a) above), provided,
     however, that such dividend (but not the declaration thereof) shall be
     included in the calculation of the amount of Restricted Payments;
 
          (ii) the purchase, redemption or other acquisition or retirement for
     value of any shares of Capital Stock of the Company in exchange for, or out

     (other than to a Restricted Subsidiary) of, shares of Qualified Capital
     Stock of the Company, provided, however, that (A) such purchase, redemption
     or other acquisition or retirement shall be excluded in the calculation of
     the amount of Restricted Payments, and (B) the aggregate net cash proceeds
     (to the extent used for such purchase, redemption, acquisition or
     retirement) and the Fair Market Value of such Capital Stock received by the
     Company from such issuance and sale shall be excluded from the calculation
     of amounts available for Restricted Payments under clause (3) of paragraph
     (a) above;
 
          (iii) the purchase, redemption, defeasance or other acquisition or
     retirement for value of any Subordinated Indebtedness in exchange for, or
     out of the net cash proceeds of a substantially concurrent issuance and

     Capital Stock of the Company, provided, however, that (A) such purchase,
     redemption, defeasance or other acquisition or retirement shall be excluded
     in the calculation of the amount of Restricted Payments, and (B) the
     aggregate net cash proceeds (to the extent used for such purchase,
     redemption, defeasance, acquisition or retirement) and the Fair Market
     Value of such Subordinated Indebtedness received by the Company from such
     issuance and sale shall be excluded from the calculation of amounts
     available for Restricted Payments under clause (3) of paragraph (a) above;
 
                                       79
<PAGE>   84
 
          (iv) the purchase, redemption, defeasance or other acquisition or
     retirement for value of Subordinated Indebtedness in exchange for, or out
     of the net cash proceeds of a substantially concurrent incurrence (other
     than to a Restricted Subsidiary) of, new Subordinated Indebtedness so long
     as (A) the principal amount of such new Indebtedness does not exceed (1)
     the principal amount (or, if such Subordinated Indebtedness being
     refinanced was incurred with original issue discount, the aggregate
     accreted value as of the date of determination) of the Subordinated
     Indebtedness being so purchased, redeemed, defeased, acquired or retired,
     plus (2) the lesser of the amount of any premium required to be paid in
     connection with such refinancing pursuant to the terms of the Subordinated
     Indebtedness being refinanced or the amount of any premium reasonably
     determined by the Company as necessary to accomplish such refinancing plus
     (3) the amount of any fees and expenses incurred to accomplish such
     refinancing, (B) such new Subordinated Indebtedness is subordinated to the
     Notes to the same extent as such Subordinated Indebtedness so purchased,
     redeemed, defeased, acquired or retired and (C) such new Subordinated
     Indebtedness has an Average Life equal to or greater than the Average Life
     of the Indebtedness being refinanced and a final Stated Maturity of
     principal later than the final Stated Maturity of principal of the
     Indebtedness being refinanced, provided, however, that such purchase,
     redemption, defeasance or other acquisition or retirement shall be excluded
     in the calculation of the amount of Restricted Payments; and
 
          (v) the repurchase of Warrants in accordance with the terms of the
     Warrant Agreement, provided, however, that such repurchase shall be
     excluded in the calculation of the amount of Restricted Payments.
 
     (c) In computing Consolidated Cash Flow and Consolidated Interest Expense
of the Company under paragraph (a) above, (1) the Company shall use audited
financial statements for the portions of the relevant period for which audited
financial statements are available on the date of determination and unaudited
financial statements and other current financial data based on the books and
records of the Company for the remaining portion of such period and (2) the
Company shall be permitted to rely in good faith on the financial statements and
other financial data derived from the books and records of the Company that are
available on the date of determination. If the Company makes a Restricted
Payment which, at the time of the making of such Restricted Payment would in the
good faith determination of the Company be permitted under the requirements of
the Indenture, such Restricted Payment shall be deemed to have been made in
compliance with the Indenture notwithstanding any subsequent adjustments made in
good faith to the Company's financial statements affecting Consolidated Cash
Flow and Consolidated Interest Expense of the Company for any period. (Section
1011)
 
     Limitation on Issuances and Sales of Capital Stock of Restricted
Subsidiaries.  The Company (a) will not permit any Restricted Subsidiary to
issue any Capital Stock (other than to the Company or a Wholly Owned Restricted
Subsidiary) and (b) will not permit any Person (other than the Company or a
Wholly Owned Restricted Subsidiary) to own any Capital Stock of any Restricted
Subsidiary; provided, however, that this covenant shall not prohibit (i) the
sale or other disposition of all, but not less than all, of the issued and
outstanding Capital Stock of any Restricted Subsidiary owned by the Company and
all Restricted Subsidiaries in compliance with the other provisions of the
Indenture and (ii) the ownership by directors of director's qualifying shares or
the ownership by foreign nationals of Capital Stock of any Restricted
Subsidiary, to the extent mandated by applicable law. (Section 1012)
 
     Limitation on Transactions with Affiliates.  The Company will not, and will
not permit any Restricted Subsidiary to enter into or suffer to exist, directly
or indirectly, any transaction or series of related transactions (including,
without limitation, the sale, purchase, exchange or lease of assets, property or
services) with, or for the benefit of, any Affiliate of the Company or any
Restricted Subsidiary (other than the Company or a Wholly Owned Restricted
Subsidiary) unless such transaction is entered into in good faith and (i) such
transaction or series of transactions are fair and reasonable to the Company or
such Restricted Subsidiary, as the case may be, and are on terms that are no
less favorable to the Company or such Restricted Subsidiary, as the case may be,
than those that could have been obtained in an arm's-length transaction with a
third party that is not an Affiliate, (ii) with respect to any transaction or
series of related transactions involving aggregate consideration equal to or
greater than US$5 million, the Company will deliver an Officers' Certificate to
the Trustee certifying that such transaction or series of transactions complies
with clause (i) above and such transaction or series of related transactions has
been approved by a majority of the Disinterested Directors of
 
                                       80
<PAGE>   85
 
the Company or, in the event no members of the Board of Directors of the Company
are Disinterested Directors with respect to such transaction or series of
transactions, the Company will obtain a written opinion from an internationally
recognized United States, United Kingdom or European investment banking firm to
the effect that such transaction or series of related transactions is fair to
the Company or its Restricted Subsidiary, as the case may be, from a financial
point of view and (iii) with respect to any transaction or series of related
transactions involving aggregate consideration in excess of US $10 million, the
Board of Directors will approve the fairness of such transaction after the
Company has obtained a written opinion from an internationally recognized United
States, United Kingdom or European investment banking firm to the effect set
forth in the preceding clause (ii); provided, however, that no opinion from an
investment banking firm will be required with respect to interconnection
agreements entered into by the Company or any Restricted Subsidiary in the
ordinary course of business and provided further that this covenant will not
restrict (1) the Company from paying reasonable and customary regular
compensation and fees to directors of the Company or any Restricted Subsidiary
who are not employees of the Company or any Restricted Subsidiary, (2) the
performance of the Company's obligations under agreements existing on the Issue
Date and listed on a schedule to the Indenture; provided that any amendments or
modifications to the terms of such agreements shall be no less favorable to the
Company than the terms existing on the Issue Date, (3) the grant of stock
options or similar rights to acquire Capital Stock to employees and directors of
the Company pursuant to plans approved by the Board of Directors provided that,
in the aggregate, the shares underlying such options or similar rights issued
since the Issue Date (exclusive of any shares underlying such options or similar
rights required to be issued by law) shall not exceed 5% of the outstanding
Common Stock of the Company on a fully diluted basis at the date of
determination, (4) loans or advances to employees in the ordinary course of
business in an aggregate amount not to exceed US$1 million at any one time
outstanding and (5) any Restricted Payment permitted to be paid pursuant to the
covenant described under "-- Limitation on Restricted Payments". (Section 1013)
 
     Limitation on Liens.  The Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, create, incur, assume or
suffer to exist any Lien of any kind (other than Permitted Liens) on or with
respect to any of its property or assets, including any shares of stock or
indebtedness of any Restricted Subsidiary, whether owned at the date of the
Indenture or thereafter acquired, or any income, profits or proceeds therefrom,
or assign or otherwise convey any right to receive income thereon, unless (x) in
the case of any Lien securing Subordinated Indebtedness, the Notes are secured
by a Lien on such property, assets or proceeds that is senior in priority to
such Lien and (y) in the case of any other Lien, the Notes are equally and
ratably secured with the obligation or liability secured by such Lien. (Section
1014)
 
     Purchase of Notes upon a Change of Control.  If a Change of Control shall
occur at any time, then each holder of Notes will have the right to require that
the Company purchase such holder's Notes, in whole or in part in integral
multiples of US$1,000, at a purchase price (the "Change of Control Purchase
Price") in cash in an amount equal to 101% of the Accreted Value thereof plus
accrued interest, if any, to the date of purchase (the "Change of Control
Purchase Date"), pursuant to the offer described below (the "Change of Control
Offer") and the other procedures set forth in the Indenture.
 
     Within 15 days following any Change of Control, the Company shall notify
the Trustee thereof and give written notice of such Change of Control to each
holder of Notes by first-class mail, postage prepaid, at the address of such
holder appearing in the security register, stating, among other things, (i) the
purchase price and the purchase date, which shall be a Business Day no earlier
than 30 days nor later than 60 days from the date such notice is mailed, or such
later date as is necessary to comply with requirements under the Exchange Act or
any applicable securities laws or regulations; (ii) that any Note not tendered
will continue to accrue interest or accrete in value, as the case may be; (iii)
that, unless the Company defaults in the payment of the purchase price, any
Notes accepted for payment pursuant to the Change of Control Offer shall cease
to accrue interest or accrete in value after the Change of Control Purchase
Date; and (iv) certain other procedures that a holder of Notes must follow to
accept a Change of Control Offer or to withdraw such acceptance. (Section 1015)
 
     If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
Purchase Price for all of the Notes that might be delivered by
 
                                       81
<PAGE>   86
 
holders of the Notes seeking to accept the Change of Control Offer. The failure
of the Company to make or consummate the Change of Control Offer or pay the
Change of Control Purchase Price when due would result in an Event of Default
and would give the Trustee and the holders of the Notes the rights described
under "-- Events of Default".
 
     The existence of a holder's right to require the Company to purchase such
holder's Notes upon a Change of Control may deter a third party from acquiring
the Company in a transaction that constitutes a Change of Control.
 
     The Change of Control purchase feature is a result of negotiations between
the Company and the Initial Purchasers. Management has no present intention to
engage in a transaction involving a Change of Control, although it is possible
that the Company would decide to do so in the future. Subject to the limitations
discussed below, the Company could, in the future, enter into certain
transactions, including acquisitions, refinancings or other recapitalizations,
that would not constitute a Change of Control under the Indenture, but that
could increase the amount of indebtedness outstanding at such time or otherwise
affect the Company's capital structure or credit ratings. Restrictions on the
ability of the Company to incur additional Indebtedness are contained in the
covenants described under "-- Certain Covenants -- Limitation on Indebtedness",
"-- Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries", "-- Limitation on Liens" and "-- Limitation on Sale and Leaseback
Transactions". Such restrictions can only be waived with the consent of the
holders of a majority in principal amount of the Notes then outstanding. Except
for the limitations contained in such covenants, however, the Indenture will not
contain any covenants or provisions that may afford holders of the Notes
protection in the event of a highly leveraged transaction.
 
     As indicated under "-- Prepayment Events Prior to First Anniversary," the
Company is currently prohibited under Colombian law from making any prepayment
of the Notes, including pursuant to a Change of Control Offer, on or prior to
the first anniversary of the Issue Date, and if the Company is required to make
a Change of Control Offer while such prohibition is in effect, the Company will
be required to deposit with the Trustee cash and/or United States Government
Obligations in an amount sufficient (without taking into account the payment of
interest thereon) to acquire all of the Notes on the first Business Day after
the first anniversary of the Issue Date. Under current Colombian law, any
prepayment of the Notes within three years of the Issue Date and after the
one-year period described in the preceding sentence resulting in more than 40%
of the aggregate principal amount at maturity of the Notes being redeemed would
impose certain deposit requirements on the Company, and the Company will be
required to comply with applicable law, including making such deposit should
such requirement then exist, prior to consummating any Change of Control Offer.
See "-- Prepayment Events Prior to Third Anniversary" and "Foreign Investment
and Exchange Controls in Colombia".
 
     The Company will comply with any applicable securities laws and regulations
in connection with a Change of Control Offer. (Section 1015)
 
     The Company will not enter into any agreement (other than the Bank Credit
Agreement or agreements governing Indebtedness in effect on the date of the
Indenture) that would prohibit the Company from making a Change of Control Offer
to purchase the Notes or, if such Change of Control Offer is made, to pay for
the Notes tendered for purchase. (Section 1015)
 
     Limitation on Sale of Assets.  (a) The Company will not, and will not
permit any Restricted Subsidiary to, engage in any Asset Sale unless (i) the
consideration received by the Company or such Restricted Subsidiary for such
Asset Sale is not less than the Fair Market Value of the assets subject to such
Asset Sale (as determined by the Board of Directors of the Company, whose
determination shall be conclusive and evidenced by a Board Resolution), (ii) the
consideration received by the Company or the relevant Restricted Subsidiary in
respect of such Asset Sale consists of at least 85% cash or Cash Equivalents and
(iii) immediately before and immediately after giving effect to such Asset Sale,
no Default or Event of Default shall have occurred and be continuing or be
anticipated to occur.
 
     (b) If the Company or any Restricted Subsidiary engages in an Asset Sale,
the Company may use the Net Cash Proceeds thereof, within 12 months after the
later of such Asset Sale or the receipt of such Net
 
                                       82
<PAGE>   87
 
Cash Proceeds, to (i) permanently repay or prepay any then outstanding secured
Indebtedness of the Company under the Bank Credit Agreement or other secured
Indebtedness of the Company that is not subordinated to payment of the Notes or
Indebtedness of any Restricted Subsidiary or (ii) invest (or enter into a
legally binding agreement to invest) in properties and assets that will be used
in businesses of the Company or its Restricted Subsidiaries, as the case may be,
that (x) existed on the date of the Indenture or (y) is a Permitted
Telecommunications Business. If any such legally binding agreement to invest
such Net Cash Proceeds is terminated, then the Company may, within 90 days of
such termination or within 12 months of such Asset Sale, whichever is later,
invest such Net Cash Proceeds as provided in clause (i) or (ii) (without regard
to the parenthetical contained in such clause (ii)) above. The amount of such
Net Cash Proceeds not so used as set forth above in this paragraph (b)
constitutes "Excess Proceeds".
 
     (c) When the aggregate amount of Excess Proceeds exceeds US$10 million, the
Company shall, within 15 business days, make an offer to purchase (an "Excess
Proceeds Offer") from all holders of Notes, on a pro rata basis, in accordance
with the procedures set forth below, the maximum principal amount of Notes that
may be purchased with the Excess Proceeds (rounded down to the nearest multiple
of $1,000). The offer price as to each Note shall be payable in cash in an
amount equal to 100% of the Accreted Value of such Note plus accrued interest,
if any, to the date such Excess Proceeds Offer is consummated. To the extent
that the aggregate principal amount of Notes tendered pursuant to an Excess
Proceeds Offer is less than the Excess Proceeds, the Company may use such
deficiency for general corporate purposes. If the aggregate principal amount of
Notes validly tendered and not withdrawn by holders thereof exceeds the Excess
Proceeds, Notes to be purchased will be selected on a pro rata basis. Upon
completion of such Excess Proceeds Offer, the amount of Excess Proceeds shall be
reset to zero. (Section 1016)
 
     As indicated under "-- Prepayment Events Prior to First Anniversary," the
Company's ability to prepay the Notes, including pursuant to an Excess Proceeds
Offer, on or prior to the first anniversary of the Issue Date is prohibited by
Colombian law, and if the Company is required to make an Excess Proceeds Offer
while such prohibition is in effect, the Company will be required to deposit
with the Trustee cash and/or United States Government Obligations in an amount
sufficient (without taking into account the payment of interest thereon) to
acquire the Notes on the first Business Day after the first anniversary of the
Issue Date. Under current Colombian law, any purchase of the Notes within three
years of the Issue Date and after the one-year period described in the preceding
sentence resulting in more than 40% of the aggregate principal amount at
maturity of the Notes being redeemed or repurchased would impose certain deposit
requirements on the Company, and the Company may elect to make such deposits or
purchase the Notes up to such limit and deposit with the Trustee amounts
sufficient to acquire the remainder of the Notes on the first Business Day after
the third anniversary of the Issue Date. If the Company shall have made the
deposit with the Trustee as described in this paragraph, it will not be in
default of its obligations to make an Excess Proceeds Offer prior to the day on
which the applicable Notes are to be acquired pursuant to this paragraph. See
"-- Prepayment Events Prior to Third Anniversary" and "Foreign Investment and
Exchange Controls in Colombia".
 
     Limitation on Sale and Leaseback Transactions.  The Company will not, and
will not permit any Restricted Subsidiary to, directly or indirectly, enter into
any Sale and Leaseback Transaction with respect to any property or assets
(whether now owned or hereafter acquired), unless the sale or transfer of such
property or assets to be leased is treated as an Asset Sale and the Company
complies with the "Limitation on Sale of Assets" covenant. (Section 1017)
 
     Limitation on the Activities of the Company.  The Company and its
Restricted Subsidiaries will not engage in any business other than the business
of the Company or its Restricted Subsidiaries existing on the Issue Date and any
Permitted Telecommunications Business and the making of Investments permitted by
Section 1011. (Section 1018)
 
     Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries.  The Company will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to (a) pay dividends, in cash or otherwise,
or make any other distributions on or in respect of its Capital Stock, (b) pay
any Indebtedness owed to the Company or any other Restricted
 
                                       83
<PAGE>   88
 
Subsidiary that, directly or indirectly, owns any Capital Stock of such
Restricted Subsidiary, (c) make loans or advances to the Company or any other
Restricted Subsidiary that, directly or indirectly, owns any Capital Stock of
such Restricted Subsidiary or (d) transfer any of its properties or assets to
the Company or any other Restricted Subsidiary that, directly or indirectly,
owns any Capital Stock of such Restricted Subsidiary (other than customary
restrictions on transfers of property subject to a Lien permitted under the
Indenture that would not materially adversely affect the Company's ability to
satisfy its obligations under the Notes and the Indenture), except, in each
case, for such encumbrances or restrictions existing under or by reason of (i)
the Notes and the Indenture, (ii) any agreement in effect on the Issue Date,
(iii) applicable law, (iv) customary provisions restricting subletting or
assignment of any lease or assignment of any other contract to which the Company
or any Restricted Subsidiary is a party or to which any of their respective
properties or assets are subject, (v) any agreement or other instrument of a
Person, or pertaining to property or assets, acquired by the Company or any
Restricted Subsidiary in existence at the time of such acquisition (but not
created in contemplation thereof), which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than
the Person, or the property or assets of the Person, so acquired, (vi) any Lien
permitted by the "Limitation on Liens" covenant, (vii) any encumbrance or
restriction contained in contracts for sales of assets or Capital Stock of a
person with respect to the assets or Capital Stock to be sold (or the assets
owned by the Person whose Capital Stock is to be sold) pursuant to such contract
that terminates upon the earlier of the termination of such agreement or the
consummation of such sale and (viii) any encumbrance or restriction existing
under any agreement that extends, renews, refinances or replaces the agreements
containing the encumbrances or restrictions in the foregoing clauses (i), (ii)
and (v); provided that the terms and conditions of any such encumbrances or
restrictions are not materially less favorable to the holders of the Notes than
those under or pursuant to the agreement so extended, renewed, refinanced or
replaced. (Section 1019)
 
     Reports.  The Company will file with the Trustee and provide the holders of
Notes, within 15 days after it files them with the SEC, copies of its annual and
quarterly reports and other information, documents and other reports (or copies
of such portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which the Company is required to file with the SEC pursuant to
Section 13(a) or 15(d) of the Exchange Act. Notwithstanding that the Company may
not be required to remain subject to the reporting requirements of Section 13(a)
or 15(d) of the Exchange Act or otherwise report on an annual and quarterly
basis on forms provided for such annual and quarterly reporting pursuant to
rules and regulations promulgated by the SEC, the Company will file with or
furnish to the SEC and provide to the Trustee and to the holders of Notes and
potential purchasers of Notes upon written request to the Trustee by any holder
of Notes, potential purchaser of Notes or Initial Purchaser: (i) within 140 days
after the end of each fiscal year, annual reports on Form 20-F (or any successor
form) containing the information required to be contained therein (or required
in such successor form); (ii) within 60 days after the end of each of the first
three fiscal quarters of each fiscal year, reports on Form 6-K (or any successor
form) containing substantially the same information required to be contained in
Form 10-Q (or required in any successor form); and (iii) promptly from time to
time after the occurrence of an event required to be therein reported, such
other reports on Form 6-K (or any successor form) containing substantially the
same information required to be contained in Form 8-K (or required in any
successor form). Financial statements of the Company contained in any such
report will be prepared in accordance with Colombian GAAP and each such report
referred to in clauses (i) and (ii) above will contain a reconciliation to U.S.
GAAP consistently applied and will be prepared in accordance with the applicable
rules and regulations of the SEC. (Section 1009)
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     The Company will not, in a single transaction or through a series of
transactions, consolidate with or merge with or into any other Person or sell,
assign, convey, transfer, lease or otherwise dispose of all or substantially all
of its properties and assets as an entirety to any other Person or Persons or
permit any of its Restricted Subsidiaries to enter into any such transaction or
series of transactions if such transaction or series of transactions, in the
aggregate, would result in the sale, assignment, conveyance, transfer, lease or
other disposition of all or substantially all of the properties and assets of
the Company and its Restricted Subsidiaries on a consolidated basis as an
entirety to any other Person or Persons, unless at the time and immediately
after
 
                                       84
<PAGE>   89
 
giving effect thereto (i) either (a) the Company will be the continuing
corporation or (b) the Person (if other than the Company) formed by such
consolidation or into which the Company or such Restricted Subsidiary is merged
or the Person that acquires by sale, assignment, conveyance, transfer, lease or
disposition all or substantially all the properties and assets of the Company
and its Restricted Subsidiaries on a consolidated basis as an entirety (the
"Surviving Entity") (1) will be a corporation duly organized and validly
existing under the laws of Colombia and (2) will expressly assume, by a
supplemental indenture in form satisfactory to the Trustee, the Company's
obligation for the due and punctual payment of the principal of, premium, if
any, and interest on all the Notes and the performance and observance of every
covenant of the Indenture on the part of the Company to be performed or
observed; (ii) immediately before and immediately after giving effect to such
transaction or series of transactions on a pro forma basis (and treating any
obligation of the Company or any Restricted Subsidiary incurred in connection
with or as a result of such transaction or series of transactions as having been
incurred at the time of such transaction), no Default or Event of Default will
have occurred and be continuing; (iii) immediately after giving effect to such
transaction or series of transactions on a pro forma basis (and treating any
obligation of the Company or any Restricted Subsidiary incurred in connection
with or as a result of such transaction or series of transactions as having been
incurred at the time of such transaction), the Consolidated Net Worth of the
Company (or of the Surviving Entity if the Company is not the continuing obligor
under the Indenture) is equal to or greater than the Consolidated Net Worth of
the Company immediately prior to such transaction or series of transactions; and
(iv) immediately after giving effect to such transaction or series of
transactions on a pro forma basis (on the assumption that the transaction or
series of transactions occurred on the first day of the most recent full fiscal
quarter for which financial statements are available prior to the consummation
of such transaction or series of transactions with the appropriate adjustments
with respect to the transaction or series of transactions being included in such
pro forma calculation), the Company (or the Surviving Entity if the Company is
not the continuing obligor under the Indenture) could incur at least US$1.00 of
additional Indebtedness (other than Permitted Indebtedness) under the provisions
of the "Limitation on Indebtedness" covenant. (Section 801)
 
     In connection with any such consolidation, merger, sale, assignment,
conveyance, transfer, lease or other disposition, the Company or the Surviving
Entity shall have delivered to the Trustee, in form and substance reasonably
satisfactory to the Trustee, an Officers' Certificate (attaching the authentic
computations to demonstrate compliance with clauses (iii) and (iv) above) and an
opinion of counsel, each stating that such consolidation, merger, sale,
assignment, conveyance, transfer, lease or other disposition, and if a
supplemental indenture is required in connection with such transaction, such
supplemental indenture, comply with the requirements of the Indenture and that
all conditions precedent therein provided for relating to such transaction have
been complied with. (Section 801)
 
     Upon any consolidation or merger, or any sale, assignment, conveyance,
transfer, lease or disposition of all or substantially all of the properties and
assets of the Company in accordance with the immediately preceding paragraphs in
which the Company is not the continuing obligor under the Indenture, the
Surviving Entity shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under the Indenture with the same effect
as if such successor had been named as the Company therein. When a successor
assumes all the obligations of its predecessor under the Indenture or the Notes,
the predecessor shall be released from those obligations; provided that in the
case of a transfer by lease, the predecessor shall not be released from the
payment of principal and interest on the Notes. (Section 802)
 
EVENTS OF DEFAULT
 
          The following will be "Events of Default" under the Indenture:
 
          (i) default in the payment of any interest on any Note when it becomes
     due and payable and continuance of such default for a period of 30 days;
 
          (ii) default in the payment of the principal of or premium, if any, on
     any Note at its Maturity (upon acceleration, optional redemption, required
     purchase or otherwise);
 
          (iii) default in the performance, or breach, of the provisions
     described in "Consolidation, Merger and Sale of Assets," the failure to
     make or consummate a Change of Control Offer in accordance with
 
                                       85
<PAGE>   90
 
     the provisions of the "Purchase of Notes upon a Change of Control" covenant
     or the failure to make or consummate an Excess Proceeds Offer in accordance
     with the provisions of the "Limitation on Disposition of Proceeds of Asset
     Sales" covenant;
 
          (iv) default in the performance, or breach, of any covenant or
     warranty of the Company contained in the Indenture (other than a default in
     the performance, or breach, of a covenant or warranty which is specifically
     dealt with in clauses (i), (ii) or (iii) above) and continuance of such
     default or breach for a period of 30 days after written notice shall have
     been given to the Company by the Trustee or to the Company and the Trustee
     by the holders of at least 25% in aggregate principal amount of the Notes
     then outstanding;
 
          (v) (A) one or more defaults in the payment of principal of or
     premium, if any, on Indebtedness of the Company or any Subsidiary
     aggregating US$3 million or more, when the same becomes due and payable at
     the stated maturity thereof, and such default or defaults shall have
     continued after any applicable grace period and shall not have been cured
     or waived or (B) Indebtedness of the Company or any Subsidiary aggregating
     US$3 million or more shall have been accelerated or otherwise declared due
     and payable, or required to be prepaid or repurchased (other than by
     regularly scheduled required prepayment prior to the stated maturity
     thereof);
 
          (vi) any holder of any Indebtedness in excess of US$3 million in the
     aggregate of the Company or any Subsidiary shall commence judicial
     proceedings, or take other action to foreclose on any assets of the Company
     or any Subsidiary that have been pledged to or for the benefit of such
     Person to secure such Indebtedness pursuant to the terms of any agreement
     or instrument evidencing any such Indebtedness of the Company or any
     Subsidiary or in accordance with applicable law subsequent to a default in
     the performance, or breach, of any covenant or warranty of the Company
     contained in any agreement or instrument evidencing any such Indebtedness;
 
          (vii) one or more final judgments or orders shall be rendered against
     the Company or any Subsidiary for the payment of money, either individually
     or in an aggregate amount, in excess of US$3 million and shall not be
     discharged and either (A) an enforcement proceeding shall have been
     commenced by any creditor upon such judgment or order and shall not have
     been stayed or (B) there shall have been a period of 60 consecutive days
     during which a stay of enforcement of such judgment or order, by reason of
     a pending appeal or otherwise, was not in effect;
 
          (viii) the occurrence of certain events of bankruptcy, insolvency or
     reorganization with respect to the Company or any Subsidiary; or
 
          (ix) the Company does not continue to be the holder of the Concession
     (provided that the pledge of the Concession as security under the Bank
     Facility shall not be deemed to be a transfer of the Concession) or the
     Concession to provide cellular service is not in full force and effect.
     (Section 501)
 
     If an Event of Default (other than as specified in clause (viii) above)
shall occur and be continuing, the Trustee or the holders of not less than 25%
in aggregate principal amount of the Notes then outstanding, by written notice
to the Company (and to the Trustee if such notice is given by the holders), may,
and the Trustee upon the written request of such holders shall, declare the
principal of, premium, if any, and accrued interest on all of the outstanding
Notes immediately due and payable, and upon any such declaration all such
amounts payable in respect of the Notes shall become immediately due and
payable. If an Event of Default specified in clause (viii) above occurs and is
continuing, then the principal of, premium, if any, and accrued interest on all
of the outstanding Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
holder of Notes. (Section 502)
 
     At any time after a declaration of acceleration under the Indenture, but
before a judgment or decree for payment of the money due has been obtained by
the Trustee, the holders of a majority in aggregate principal amount of the
outstanding Notes, by written notice to the Company and the Trustee, may rescind
such declaration and its consequences if (a) the Company has paid or deposited
with the Trustee a sum sufficient to pay (i) all overdue interest on all Notes,
(ii) all unpaid principal of and premium, if any, on any outstanding Notes that
has become due otherwise than by such declaration of acceleration and interest
thereon at the rate
 
                                       86
<PAGE>   91
 
borne by the Notes, (iii) to the extent that payment of such interest is lawful,
interest upon overdue interest and overdue principal at the rate borne by the
Notes, (iv) all sums paid or advanced by the Trustee under the Indenture and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and (b) all Events of Default, other than the
non-payment of amounts of principal of, premium, if any, or interest on the
Notes that has become due solely by such declaration of acceleration, have been
cured or waived. No such rescission shall affect any subsequent default or
impair any right consequent thereon. (Section 502)
 
     The holders of not less than a majority in aggregate principal amount of
the outstanding Notes may, on behalf of the holders of all the Notes, waive any
past defaults under the Indenture, except a default in the payment of the
principal of, premium, if any, or interest on any Note, or in respect of a
covenant or provision which under the Indenture cannot be modified or amended
without the consent of the holder of each Note outstanding. (Section 513)
 
     If a Default or an Event of Default occurs and is continuing and is known
to the Trustee, the Trustee will mail to each holder of the Notes notice of the
Default or Event of Default within 30 days after the occurrence thereof. Except
in the case of a Default or an Event of Default in payment of principal of,
premium, if any, or interest on any Notes, the Trustee may withhold the notice
to the holders of such Notes if a committee of its trust officers in good faith
determines that withholding the notice is in the interests of the holders of the
Notes. (Section 601)
 
     The Company is required to furnish to the Trustee annual statements as to
the performance by the Company of its obligations under the Indenture and as to
any default in such performance. The Company is also required to notify the
Trustee within five Business Days of the occurrence of any Default.
 
     The Trust Indenture Act contains limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases or to realize on certain property received by it in respect of any
such claims, as security or otherwise. The Trustee is permitted to engage in
other transactions; provided that if it acquired any conflicting interest, it
must eliminate such conflict upon the occurrence of an Event of Default or else
resign.
 
BANKRUPTCY ("CONCORDATO")
 
     Under Colombian law, the procedure for bankruptcy differs from that in the
United States. Under Law 222/1995, which will come into effect as of June 21,
1996, upon admittance of the Company to the "concordato" proceeding the Company
cannot make any payment or settle any of its obligations (including the Notes
and the Bank Facility) without obtaining a written consent of the
Superintendency of Corporations. Furthermore, the Company is restricted from
making any payments, as from the same date of admission to "concordato" and
until (i) the "concordato" proceeding is terminated by the Superintendency of
Corporations because of failure to reach any agreement or (ii) an agreement is
reached between the Company and its creditors during the "concordato" and is
declared by the Superintendency of Corporations to have been (x) fulfilled or
(y) terminated due to a breach of obligations under such agreement. Any creditor
who fails to file a timely claim under the "concordato" will be barred from the
"concordato" proceeding (except if during any hearing such creditor is accepted
to be a party of the "concordato" agreement) and cannot receive any payment from
the debtor during the period referred to in the preceding sentence, although the
statute of limitations applicable to such creditor's claim will be tolled during
such period. The Concession cannot be terminated by the Ministry of
Communications based on the grounds that the Company is then the subject of a
"concordato" proceeding (See "Regulation -- Termination Upon Default in
Performance").
 
DEFEASANCE OR COVENANT DEFEASANCE OF INDENTURE
 
     The Company may, at its option and at any time, elect to have the
obligations of the Company upon the Notes discharged with respect to the
outstanding Notes ("legal defeasance"). Such defeasance means that the Company
will be deemed to have paid and discharged the entire Indebtedness represented
by the outstanding Notes and to have satisfied all their other obligations under
such Notes and the Indenture insofar as such Notes are concerned except for (i)
the rights of holders of outstanding Notes to receive payments in
 
                                       87
<PAGE>   92
 
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due, (ii) the Company's obligations to issue temporary Notes,
register the transfer or exchange of any Notes, replace mutilated, destroyed,
lost or stolen Notes, maintain an office or agency for payments in respect of
the Notes and segregate and hold such payments in trust, (iii) the rights,
powers, trusts, duties and immunities of the Trustee and (iv) the defeasance
provisions of the Indenture. In addition, the Company may, at its option and at
any time, elect to have the obligations of the Company released with respect to
certain covenants set forth in the Indenture, and any omission to comply with
such obligations will not constitute a Default or an Event of Default with
respect to the Notes ("covenant defeasance"). (Sections 1301, 1302 and 1303)
 
     In order to exercise either legal defeasance or covenant defeasance, (i)
the Company must irrevocably deposit or cause to be deposited with the Trustee,
as trust funds in trust, specifically pledged as security for, and dedicated
solely to, the benefit of the holders of the Notes, cash in United States
dollars, U.S. Government Obligations (as defined in the Indenture), or a
combination thereof, in such amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants, to pay and
discharge the principal of, premium, if any, and interest on the outstanding
Notes on the Stated Maturity (or upon redemption, if applicable) of such
principal, premium, if any, or installment of interest; (ii) no (a) Default in
the payment of principal of or premium, if any, or interest on any Note or a
Default resulting from the occurrence of certain events of bankruptcy,
insolvency or reorganization, or (b) Event of Default with respect to the Notes
(other than as a result of a breach of the provisions described under
"Consolidation, Merger and Sale of Assets" arising from a merger or
consolidation occurring contemporaneously with such defeasance) will have
occurred and be continuing on the date of, or immediately after, such deposit
or, insofar as an event of bankruptcy, insolvency or reorganization is
concerned, at any time during the period ending on the 91st day after the date
of such deposit; (iii) such legal defeasance or covenant defeasance will not
result in a breach or violation of, or constitute a default under, any material
agreement or instrument to which the Company is a party or by which it is bound;
(iv) in the case of legal defeasance, the Company shall have delivered to the
Trustee an Opinion of Counsel stating that the Company has received from, or
there has been published by, the Internal Revenue Service a ruling, or since May
31, 1996, there has been a change in applicable federal income tax law, in
either case to the effect that, and based thereon such opinion shall confirm
that, the holders of the outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such defeasance had not occurred; (v)
in the case of covenant defeasance, the Company shall have delivered to the
Trustee an Opinion of Counsel to the effect that the holders of the Notes
outstanding will not recognize income, gain or loss for federal income tax
purposes as a result of such covenant defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such covenant defeasance had not occurred; and (vi)
the Company shall have delivered to the Trustee an Officers' Certificate and an
Opinion of Counsel, each stating that all conditions precedent provided for
relating to either the legal defeasance or the covenant defeasance, as the case
may be, have been complied with. (Section 1304)
 
SATISFACTION AND DISCHARGE
 
     The Indenture will cease to be of further effect (except as to surviving
rights of registration of transfer or exchange of the Notes as expressly
provided for in the Indenture) and the Trustee, at the expense of the Company,
will execute proper instruments acknowledging satisfaction and discharge of the
Indenture when (i) either (a) all the Notes theretofore authenticated and
delivered (other than destroyed, lost or stolen Notes which have been replaced
or paid and Notes for whose payment money has been deposited in trust with the
Trustee or any Paying Agent or segregated and held in trust by the Company and
thereafter repaid to the Company or discharged from such trust as provided for
in the Indenture) have been delivered to the Trustee for cancellation or (b) all
Notes not theretofore delivered to the Trustee for cancellation (x) have become
due and payable, (y) will become due and payable at Stated Maturity within one
year or (z) are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company, and the Company has
irrevocably deposited or caused to be deposited with the Trustee as trust funds
in trust for such purpose an amount sufficient to pay and discharge the entire
Indebtedness on such Notes not theretofore delivered to the
 
                                       88
<PAGE>   93
 
Trustee for cancellation, for principal of, premium, if any, and interest on the
Notes to the date of such deposit (in the case of Notes which have become due
and payable) or to the Stated Maturity or Redemption Date, as the case may be;
(ii) the Company has paid or caused to be paid all sums payable under the
Indenture by the Company; and (iii) the Company has delivered to the Trustee an
Officer's Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided in the Indenture relating to the satisfaction and
discharge of the Indenture have been complied with. (Section 401)
 
MODIFICATIONS AND AMENDMENTS
 
     Modifications and amendments of the Indenture may be made by a supplemental
indenture entered into by the Company and the Trustee with the consent
(including consents obtained in connection with a tender offer or exchange for
the Notes) of the holders of a majority in aggregate outstanding principal
amount of the Notes then outstanding; provided, however, that no such
modification or amendment may, without the consent of the holder of each
outstanding Note affected thereby: (i) change the Stated Maturity of the
principal of, or any installment of interest on, any Note, or reduce the
principal amount thereof (or premium, if any) or the rate of interest thereon or
change the coin or currency in which the principal of any Note or any premium or
the interest thereon is payable, or impair the right to institute suit for the
enforcement of any such payment after the Stated Maturity thereof (or, in the
case of redemption, on or after the Redemption Date); (ii) amend, change or
modify in any material respect the obligation of the Company to make and
consummate an Excess Proceeds Offer with respect to any Asset Sale in accordance
with the "Limitation on Sale of Assets" covenant or the obligation of the
Company to make and consummate a Change of Control Offer in the event of a
Change of Control in accordance with the "Purchase of Notes Upon a Change of
Control" covenant, including, in each case, amending, changing or modifying in
any material respect any definition relating thereto; (iii) reduce the
percentage in principal amount of outstanding Notes, the consent of whose
holders is required for any such supplemental indenture or the consent of whose
holders is required for any waiver of compliance with certain provisions of the
Indenture; (iv) modify any of the provisions relating to supplemental indentures
requiring the consent of holders or relating to the waiver of past defaults or
relating to the waiver of certain covenants, except to increase the percentage
of outstanding Notes required for such actions or to provide that certain other
provisions of the Indenture cannot be modified or waived without the consent of
the holder of each Note affected thereby; or (v) except as otherwise permitted
under "Consolidation, Merger and Sale of Assets," consent to the assignment or
transfer by the Company of any of its obligations under the Indenture. (Sections
901 and 902)
 
     Notwithstanding the foregoing, without the consent of any holder of the
Notes, the Company and the Trustee may modify or amend the Indenture: (a) to
evidence the succession of another Person to the Company or any other obligor on
the Notes, and the assumption by any such successor of the covenants of the
Company or such obligor in the Indenture and in the Notes in accordance with
"-- Consolidation, Merger, Sale of Assets;" (b) to add to the covenants of the
Company or any other obligor upon the Notes for the benefit of the holders of
the Notes or to surrender any right or power conferred upon the Company or any
other obligor upon the Notes, as applicable, in the Indenture or in the Notes;
(c) to cure any ambiguity, or to correct or supplement any provision in the
Indenture or the Notes which may be defective or inconsistent with any other

pledged or hypothecated, or in which a security interest is required to be
granted to the Trustee pursuant to the Indenture or otherwise. (Section 901)

THE TRUSTEE
 
     The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indenture. If an Event of Default has occurred and is continuing, the
Trustee will exercise such rights and powers vested in it under the Indenture
and use the same degree of care and skill in its exercise as a prudent Person
would exercise under the circumstances in the conduct of such Person's own
affairs. (Section 602)
 
     The Indenture and provisions of the Trust Indenture Act of 1939, as
amended, incorporated by reference therein contain limitations on the rights of
the Trustee thereunder, should it become a creditor of the Company, to obtain
payment of claims in certain cases or to realize on certain property received by
it in respect of any such claims, as security or otherwise. The Trustee is
permitted to engage in other transactions; provided, however, that if it
acquires any conflicting interest (as defined) it must eliminate such conflict
or resign.
 
GOVERNING LAW AND SUBMISSION TO JURISDICTION
 
     The Indenture and the Notes are governed by, and construed in accordance
with, the laws of the State of New York. The Indenture is subject to the
provisions of the Trust Indenture Act of 1939, as amended, that are required to
be part of the Indenture and shall, to the extent applicable, be governed by
such provisions. The Company has submitted to the jurisdiction of any United
States federal or state court located in New York, New York for the purposes of
all legal actions and proceedings instituted in connection with Notes and the
Indenture. The Company has appointed CT Corporation System as its authorized
agent upon which process may be served in any such action. See "Enforceability
of Civil Liabilities" and "Enforcement of Foreign Judgments in Colombia".

                    BOOK-ENTRY, DELIVERY AND FORM PROCEDURES
 
GENERAL
 
     The Old Notes offered and sold in reliance on Regulation S under the
Securities Act were initially represented by a single, permanent Global Note in
definitive, fully registered book-entry form (the "Regulation S Global Note")
which was registered in the name of a nominee of DTC and deposited on behalf of
the purchasers of the Notes represented thereby with the Trustee as custodian
for DTC for credit to the respective accounts of the purchasers (or to such
other accounts as they may direct) at the Euroclear System ("Euroclear") or
Cedel Bank S.A. ("CEDEL"). The Old Notes offered and sold to "qualified
institutional buyers" ("QIBs") in reliance on Rule 144A under the Securities Act
were initially represented by a single, permanent Global Note in definitive,
fully registered book-entry form (the "Rule 144A Global Note," and, together
with the Regulation S Global Note, the "Old Global Notes") which was registered
in the name of a nominee of DTC and deposited on behalf of purchasers of the
Notes represented thereby with the Trustee as custodian for DTC for credit to
the respective accounts of the purchasers (or to such other accounts as they may
direct) at DTC. The Old Notes offered and sold to institutional "accredited
investors" as defined in Rule 501(a)(1), (2), (3) and (7) under the Securities
Act were initially delivered in certificated fully registered form only (the
"Restricted Certificated Notes"). Except as set forth below, it is expected that
the New Notes Issued pursuant to the Exchange Offer will be issued in global
form (the "New Global Notes", and, with the Old Global Notes, the "Global
Notes").
 
GLOBAL NOTES
 
     Upon the issuance of the New Global Notes, DTC or its custodian will
credit, on its internal system, the respective principal amount of the
individual beneficial interests represented by such New Global Note to the
accounts of persons who have accounts with such depositary. Such accounts
initially will be designated by the Exchange Agent. Ownership of beneficial
interests in a New Global Note will be limited to persons who are members of, or
participants in, DTC (the "Agent Members") or persons who hold interests through
Agent Members. Ownership of beneficial interests in the New Global Notes will be
shown on, and the transfer of that ownership will be effected only through,
records maintained by DTC or its nominee (with respect to interests of Agent
Members) and the records of Agent Members (with respect to interests of persons
other than Agent members).
 
     So long as DTC, or its nominee, is a registered holder of a Global Note,
DTC or such nominee, as the case may be, will be considered the absolute owner
or holder of the Notes represented by such Global Note for all purposes under
the Indenture and the Notes, and Agent Members, as well as any other persons on
whose behalf Agent Members may act (including Euroclear and CEDEL and account
holders and participants therein), will have no rights under the Indenture or
under a Global Note. Owners of beneficial interests in a Global Note will not be
considered to be the owners or holders of any Notes under the Indenture or the
Notes.
 
                                       101
<PAGE>   106
 
In addition, no beneficial owner of an interest in a Global Note will be able to
exchange or transfer that interest, except in accordance with the applicable
procedures of DTC (the "Applicable Procedures").
 
     Payments in respect of each Global Note registered in the name of DTC's
nominee will be made to the order of DTC's nominee as the registered owner of
such Global Note. None of the Company, the Trustee or the Warrant Agent will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial interests in the Global Notes or for
maintaining, supervising or reviewing any records relating to such beneficial
interests.
 
     The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Note, will immediately credit the
accounts of Agent Members with payments in the amounts proportionate to their
respective beneficial interests in the principal amount of such Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by Agent Members to owners of beneficial interests in such Global Note
held through such Agent Members be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers registered in the names of nominees for such customers. Such payments
will be the responsibility of such Agent Members.
 
     Transfers between participants in DTC will be effected in the ordinary way
in accordance with the Applicable Procedures and will be settled in same-day
funds.
 
     DTC has advised the Company that it will take any action permitted to be
taken by a holder of Notes (including the presentation of Notes for exchange as
described below) only at the direction of one or more Agent Members to whose
account the DTC interests in the Global Notes is credited and only in respect of
such portion of the aggregate principal amount of Notes as to which such Agent
Member or Agent Members has or have given such direction.
 
     The Company understands: DTC is a limited purpose trust company organized
under the laws of the State of New York, a "banking organization" within the
meaning of New York Banking Law, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the Uniform Commercial Code and a
"Clearing Agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. DTC was created to hold securities for its participants and
facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes in accounts of its
participants, thereby eliminating the need for physical movement of
certificates. Participants include securities brokers and dealers, banks, trust
companies and clearing corporations and certain other organizations. Indirect
access to the DTC system is available to others such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a participant, either directly or indirectly ("indirect participants").
 
     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the Global Notes among participants of DTC,
it is under no obligation to perform or continue to perform such procedures, and
such procedures may be discontinued at any time. Neither the Company, the
Trustee nor the Warrant Agent will have any responsibility for the performance
by DTC, its participants or indirect participants of their respective
obligations under rules and procedures governing its operations.
 
CERTIFICATED NOTES
 
     New Notes issued in exchange for Old Notes held by institutional
"accredited investors" which are not QIBs within the meaning of Rule 144A of the
Securities Act will be issued in the form of registered definitive certificates
("Certificated Notes"). Upon transfer of Certificated Notes to a QIB, such
Certificated Notes may be transferred to a Global Note upon delivery of
appropriate certifications to the Trustee.
 
     In addition, interests in a Global Note will be exchangeable or
transferable, as the case may be, for Certificated Notes if (i) DTC notifies the
Company that it is unwilling or unable to continue as depositary for such Global
Notes, or DTC ceases to be a "Clearing Agency" registered under the Exchange
Act, and a successor depositary is not appointed by the Company within 90 days,
or (ii) an Event of Default has occurred and is continuing with respect to such
Notes and Noteholders who hold more than 25% in aggregate principal amount of
the Notes at the time outstanding represented by the Global Notes advise the
Trustee through DTC in writing that the continuation of a book-entry system
through DTC (or a successor thereto) with respect to the Global Notes is no
longer required. Upon the occurrence of any of the events described in the
 
                                       102
<PAGE>   107
 
preceding sentence, the Company will cause the appropriate Certificated Notes to
be delivered. Upon the transfer, exchange or replacement of Old Notes bearing
such legend, or upon specific request for removal of such legend, the Company
shall deliver only Notes that bear a legend as to restrictions on transfer of
such Note, or shall refuse to remove such legend, as the case may be, unless
there is delivered to the Company and the Trustee a certificate in the form
provided in the Indenture or such satisfactory evidence as may reasonably be
required by the Company, which may include an opinion of United States counsel,
that neither the legend nor the restrictions on transfer set forth therein are
required to ensure compliance with the provisions of the Securities Act.

                                    TAXATION
 
     The following discussion summarizes certain Colombian and United States
federal income tax consequences of the acquisition, ownership and disposition of
Notes. Although the following discussion does not purport to describe all of the
tax considerations that may be relevant to holders of the Notes such discussion,
it summarizes the material Colombian tax consequences to Non-Colombian Holders
(as defined herein) of holding Notes and the material United States federal
income tax consequences to United States Holders (as defined herein) of holding
Notes.
 
     The statements regarding United States and Colombian tax laws and practices
set forth below are based on the laws in force and as applied in practice on the
date of this Prospectus and are subject to changes to those laws and practices,
and any relevant judicial decision, subsequent to the date of this Prospectus
which changes may be retroactive.
 
     As used herein, a "Non-Colombian Holder" means a holder that is not a
citizen or a resident of Colombia or a company or other entity not organized
under the laws of Colombia and that has no connection to Colombia other than its
investment in the Notes.
 
     As used herein, a "United States Holder" means a holder that is a citizen
or resident of the United States, a corporation created or organized in or under
the laws of the United States or any political subdivision thereof or a person
that otherwise is subject to United States federal income tax on a net income
basis in respect of the Notes.
 
     HOLDERS OF THE OLD NOTES ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS AS
TO THE UNITED STATES, COLOMBIAN OR OTHER TAX CONSEQUENCES OF THE PURCHASE,
OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE EFFECT OF ANY STATE OR
LOCAL TAX LAWS.
 
COLOMBIA
 
     The following summary is a general description of certain Colombian tax
aspects of the Notes and does not purport to be a comprehensive description of
Colombian tax aspects of the Notes. No information is provided regarding the tax
aspects of owning, holding or disposing of the securities under applicable tax
laws of any jurisdiction other than Colombia.
 
  Notes
 
     Non-Colombian Resident Holders will not be required to file any tax returns
in Colombia solely by reason of their investments in the Notes, and will not be
subject to Colombian income and remittance withholding taxes to the extent
payments on the Notes do not constitute Colombian source income. Article 25 of
the Estatuto Tributario (the "Colombian Tax Code") provides that credits
obtained abroad (including bank loans and debt securities) by Colombian
companies carrying out activities deemed to be of interest to the social and
economic development of the country, as per policies adopted by the National
Council on Economic and Social Policies (CONPES), do not generate Colombian
source income and will not be considered to be possessed in Colombia. Resolution
54 of 1992 ("Resolution 54") from CONPES establishes that all activities
pertaining to the primary, manufacturing and service sector are deemed to be of
interest to the social and economic development of the country. Under Colombian
law, the Company's activities would be categorized as being part of the service
sector. As a result, no income or remittance tax will be withheld from interest
payments on the Notes by the Company to Non-Colombian Holders.
 
     Resolution 54 may be rescinded or modified. In the event the Company's
activities were not deemed to be of interest for the social and economic
development of the country, interest payments on the Notes from the Company to
Non-Colombian Holders could be subject to withholding of income tax at the rate
of 35% and withholding of remittance tax at the rate of 7% on the net amount of
the payment after deducting the withholding of income tax. Due to the imposition
of such taxes on interest payments on the Notes, the Company generally would be
required to pay Additional Amounts to Non-Colombian Holders. See "Description of
the Notes -- Additional Amounts." Any gain realized on the sale, transfer,
exchange or other
 
                                       104
<PAGE>   109
 
disposition of a Note by a Non-Colombian Holder would not be subject to
Colombian capital gain taxes nor to Colombian income tax.
 
     The exchange of the Old Notes for the New Notes in the Exchange Offer, see
"The Exchange Offer", will not constitute a taxable event to Non-Colombian
Holders for Colombian income tax purposes. There are no regulations in Colombia
with regard to inheritance, gift or wealth taxes applicable to the Notes.
 
UNITED STATES
 
     The following deals only with Units and Notes that are held by United
States Holders, and does not deal with persons that are subject to special tax
rules, such as dealers in securities or currencies, financial institutions, life
insurance companies, tax-exempt entities, persons holding Units or Notes as a
part of a hedging or conversion transaction or a straddle, persons that own (or
are deemed for United States tax purposes to own) 10% or more of the total
combined voting power of all classes of voting stock of the Company, persons
that have a principal place of business or "tax home" outside the United States
or persons whose "functional currency" is not the U.S. dollar. The discussion
below is based upon the provisions of the United States Internal Revenue Code of
1986, as amended (the "Internal Revenue Code"), and regulations, rulings and
judicial decisions thereunder as of the date hereof; any such authority may be
repealed, revoked or modified, perhaps with retroactive effect, so as to result
in federal income tax consequences different from those discussed below.
 
Units
 
     The issue price of the Units is equal to the first price at which a
substantial amount of Units is sold to persons other than bond houses, brokers
or similar persons or organizations acting in the capacity of underwriters,
placement agents or wholesalers. The Company has been informed by the Initial
Purchasers that the issue price of the Units as so determined, was US$524.26 per
Unit. The issue price of a Unit must then be allocated for United States tax
purposes between the Note and Warrants that comprise the Unit based on their
relative fair market values at the time of issuance. The Company has allocated
US$464.49 per Unit to the Note and US$59.77 per Unit to the Warrants. The
portion of the issue price of the Unit that is allocated to the Note is the
issue price of the Note. The Company's allocation of the issue price of the
Units between the Notes and the Warrants for United States tax purposes will be
binding on each holder of a Unit, unless the holder explicitly discloses its use
of a different allocation in a manner prescribed by applicable regulations. A
holder of Units or Notes may contact the Company's Vice President -- Finance at
(574) 510-9410, in order to obtain information as to the allocation of issue
price made by the Company, as well as any other relevant information.
 
Notes
 
  Exchange of Notes
 
     The exchange of Old Notes for New Notes pursuant to the Exchange Offer
should not be treated as an exchange or other taxable event to United States
Holders. Consequently, no gain or loss should be realized by a United States
Holder upon receipt of a New Note; the holding period of the New Note should
include the holding period of the Old Note exchanged therefor and the adjusted
tax basis of the New Note should be the same as the adjusted tax basis of the
Old Note exchanged therefor.
 
  Original Issue Discount
 
     General.  The Old Notes and New Notes will be treated as having been issued
with original issue discount ("OID"). The amount of OID on a Note will be equal
to the excess of (i) the aggregate amount payable on the Note (whether
denominated as principal or as interest) over (ii) the issue price of the Note
(determined in the manner described above).
 
     The Code and the OID Regulations provide rules that require a United States
Holder of a Note to include OID in income, as ordinary interest income, before
the receipt of cash attributable to such income
 
                                       105
<PAGE>   110
 
without regard to the holder's method of accounting for tax purposes. The amount
of OID includible in gross income by a United States Holder of a Note is the sum
of the "daily portions" of OID with respect to the Note for each day during the
taxable year or portion of the taxable year in which the United States Holder
holds such Note ("accrued OID"). The daily portion is determined by allocating
to each day in any "accrual period" a pro rata portion of the OID allocable to
that accrual period. Under the OID Regulations, accrual periods with respect to
a Note may be any set of periods (which may be of varying lengths) selected by
the United States Holder as long as (i) no accrual period is longer than one
year and (ii) each scheduled payment of interest or principal on the Security
occurs on the first day or final day of an accrual period.
 
     The amount of OID allocable to an accrual period equals the product of the
Note's adjusted issue price at the beginning of the accrual period and the
Note's yield to maturity (determined on the basis of compounding at the close of
each accrual period and properly adjusted for the length of the accrual period).
The "adjusted issue price" of a Note at the beginning of the first accrual
period is the issue price and at the beginning of any accrual period thereafter
is (x) the sum of the issue price of such Note and the accrued OID for each
prior accrual period (determined without regard to the amortization of any
acquisition premium or bond premium), less (y) any prior payments on the Notes.
If a payment is made on the first day of an accrual period, then the adjusted
issue price at the beginning of such accrual period is reduced by the amount of
the payment.
 
     The OID Regulations contain certain special rules that generally allow any
reasonable method to be used in determining the amount of OID allocable to a
short initial accrual period (if all other accrual periods are of equal length),
and require that the amount of OID allocable to the final accrual period equal
the excess of the amount payable at the maturity of the Note over the Note's
adjusted issue price as of the beginning of such final accrual period.
 
     U.S. Holders of Notes generally will have to include in income increasingly
greater amounts of OID over the life of the Notes.
 
  Acquisition Premium
 
     A United States Holder that purchases a Note at its original issuance for
an amount in excess of its issue price but less than its stated redemption price
at maturity (any such excess being "acquisition premium") is permitted to reduce
the daily portions of OID by a fraction, the numerator of which is the excess of
the sum of all amounts payable on the Note after the purchase date, other than
payments of qualified stated interest, over the Note's issue price.
Alternatively, a United States Holder may elect to compute OID accruals as
described under "Original Issue Discount -- General" above, treating the United
States Holder's purchase price as the issue price.
 
  Election to Treat all Interest as Original Issue Discount
 
     Any United States Holder may elect to include in gross income all interest
that accrues on a Note using the constant yield method described above under the
heading "Original Issue Discount -- General", with the modifications described
below. For purposes of this election, interest includes stated interest, OID, de
minimis OID, market discount, de minimis market discount and unstated interest,
as adjusted by any acquisition premium.
 
     In applying the constant yield method to a Note with respect to which this
election has been made, the issue price of the Note will equal the electing
United States Holder's adjusted basis in the Note immediately after its
acquisition, and the issue date of the Note will be the date of its acquisition
by the electing United States Holder. This election is generally applicable only
to the Note with respect to which it is made and may not be revoked without the
consent of the IRS.
 
     If the election described above to apply the constant yield method to all
interest on a Note is made with respect to a Market Discount Note, as defined
below, then the electing United States Holder will be treated as having made the
election discussed below under "Notes Purchased at a Market Discount" to include
market discount in income currently over the life of all debt instruments held
or thereafter acquired by such United States Holder.
 
                                       106
<PAGE>   111
 
  Notes Purchased at a Market Discount
 
     A Note will be treated as issued at a market discount (a "Market Discount
Note") if the amount for which a United States Holder purchased a Note is less
than the Note's issue price by more than a de minimis amount.
 
     In general, any partial payment of principal on, or gain recognized on the
maturity or disposition of, a Market Discount Note will be treated as ordinary
income to the extent that such gain does not exceed the accrued market discount
on such Note. Alternatively, a United States Holder of a Market Discount Note
may elect to include market discount in income currently over the life of the
Market Discount Note. Such an election applies to all debt instruments with
market discount acquired by electing United States Holder on or after the first
day of the first taxable year to which the election applies and may not be
revoked without the consent of the IRS.
 
     Market discount accrues on a straight-line basis, unless the United States
Holder elects to accrue such discount on a constant yield to maturity basis.
Such an election is applicable only to the Note with respect to which it is made
and is irrevocable. A U.S. Holder of a Market Discount Note that does not elect
to include market discount in income currently generally will be required to
defer deductions for interest on borrowings allocable to such Note in an amount
not exceeding the accrued market discount on such Note, until the maturity or
disposition of such Note.
 
  Purchase, Sale and Retirement of the Notes
 
     A United States Holder's tax basis in a Note will generally be its U.S.
dollar cost increased by the amount of any OID or market discount included in
the United States Holder's income with respect to the Note and the amount, if
any, of income attributable to de minimis OID included in the United States
Holder's income with respect to the Note, and reduced by the sum of (i) the
amount of any payments on the Note and (ii) the amount of any amortizable bond
premium applied to reduce interest on the Note. A United States Holder generally
will recognize gain or loss on the sale or retirement of a Note equal to the
difference between the amount realized on the sale or retirement and the tax
basis of the Note. The amount realized on a sale or retirement for an amount in
foreign currency will be the U.S. dollar value of such amount on the date of
sale or retirement. Except to the extent described above under "Market Discount"
and except to the extent attributable to accrued but unpaid interest, gain or
loss recognized on the sale or retirement of a Note will be capital gain or loss
and will be long-term capital gain or loss if the Note was held for more than
one year.
 
  Foreign Tax Credit
 
     For United States foreign tax credit purposes, OID on a Note generally will
be treated as foreign-source income and as passive income, subject to the
separate foreign tax credit limitation (basket) for passive income. However, if
such OID becomes subject to Colombian withholding tax at a rate of five percent
or more, then such OID instead will be segregated in the separate foreign tax
credit basket for high withholding tax interest.
 
     Gain realized on the sale, exchange or retirement of a Note by the United
States Holder generally will be treated as United States-source income. The IRS
is authorized to issue regulations to govern the source of losses recognized on
the sale of personal property (such as the Notes); however, to date, no such
regulations have been issued. While there can be no assurance in the matter,
relevant legislative history suggests that the regulations, when and if issued,
generally should treat loss recognized by a United States Holder on the sale,
exchange or retirement of a Note as United States-source loss.

              FOREIGN INVESTMENT AND EXCHANGE CONTROLS IN COLOMBIA
 
     The current legal framework for foreign investment in Colombia was
established by Law 9 of 1991, Resolution 51 of October 1991 (the Foreign
Investment Statute) of the CONPES, and Resolution 21 of 1993 as amended by
several resolutions issued by Banco de la Republica (Central Bank). The main
guiding principles of the current regulatory framework are: (i) Equality of
Treatment: foreign and domestic investment in Colombia must receive equal
treatment and discrimination is illegal; (ii) Freedom of Access: foreign
investment is permitted in any sector of the economy except defense, national
security, the processing, disposal, and discharge of toxic, hazardous, or
radioactive waste not produced in Colombia, and real estate; (iii) Automatic
procedures: foreign investors need not follow any special authorization
procedure to invest in Colombia. However, investors should register their
investments with the Central Bank to preserve certain foreign-exchange-related
rights.
 
     Under Colombian law there are three types of foreign capital investment:
First, direct investment, which is defined as any contribution (i.e., cash and
debt capitalization) by a foreigner into the capital of an existing or newly
formed company in Colombia. Second, indirect investment, which involves any acts
or contracts by which a foreign investor makes a contribution to a company
without taking an equity position, but the income derived by the foreign
investor nevertheless depends on the profits generated by the Company. Finally,
portfolio investment which is made through a foreign capital investment fund for
the acquisition of shares and other securities traded on Colombian stock
exchanges. Foreign investment can be made in different ways, including the
transfer of foreign currency for conversion into Colombian currency as a direct
contribution to the equity of an existing or newly formed company, the
acquisition of rights, shares, or other securities, the capitalization of funds
with remittance rights, the importation of capital goods; and contributions in
kind such as technologies, trademarks, and patents.
 
     Registration of foreign capital investment (registration must be made
within the following three months, but could be extended to six months, to avoid
fines), entitles the holder to repatriate all net profits in freely convertible
currency based on the financial statements of the company, reinvest profits or
retain undistributed surpluses, capitalize the remittable amounts produced by
the investment, and remit, in freely convertible currency, the capital
reductions, portfolio liquidation, or the proceeds of the sale of investments
within Colombia. Repatriation and remittance rights can be temporarily modified
if foreign currency reserve levels fall below the equivalent of three months'
imports.
 
     Resolution 21 establishes two distinct foreign exchange markets: (i) the
formal foreign exchange market, which is conducted through authorized financial
intermediaries (each an "Authorized Intermediary") and subject to the procedures
established by Resolution 21, as amended, which requires certain specified
transactions to be carried out through such market and (ii) the free market,
which is available for all transactions not required to be conducted on the
foreign exchange market, including the exchange of foreign currency relating to
professional services, donations and sales of goods and services to tourists.
 
     Transactions conducted through the foreign exchange market are conducted at
market rates freely negotiated with authorized intermediaries (banks, financial
corporations and others). The payment of the Exercise Price of the Warrants, the
distribution by the Company of dividends of the Warrant Shares and the
remittance abroad of the proceeds of the sale in Colombia of any Warrant Shares
must be conducted through the foreign exchange market. To carry out an exchange
transaction, an exchange declaration (declaracion de cambio) must be prepared
and filed with an authorized intermediary. Conversion from Pesos to Dollars for
payments of principal and interest of the Notes will be required to be made on
the foreign exchange market through an Authorized Intermediary.
 
     Resolution 21, as amended, allows Colombian residents to incur indebtedness
in foreign currency but requires that borrowers incurring indebtedness in a
foreign currency with a term of 36 months or less, in addition to registration,
make deposits in Pesos at the Central Bank in order to be able to remit payments
in such foreign currency. Such deposits must be maintained for a term of 18
months and the deposit amount equals 50% of the total amount borrowed,
liquidated at the market representative exchange rate of the day of
constitution.
 
                                       108
<PAGE>   113
 
     There are some exceptions to the deposit requirement, including: (i)
borrowings with a final maturity of more than 36 months, but with repayments not
exceeding 40% of principal within the initial 36-month period. (If repayments
exceed 40% of principal within the initial 36-month period, a 50% deposit must
be made with respect to the portion of principal repaid during such initial
period); and (ii) borrowings obtained by Colombian residents to finance payments
to public entities (a) to buy shares or shares' preference subscription rights
in privatization processes and (b) to pay concession or license fees.
 
     In addition, any partial or total prepayment or redemption of indebtedness
in foreign currency can be done without the making of a previous deposit in
Pesos at the Central Bank after the initial 36-month period, or before that
term, without the making of a deposit, in the following cases:
 
     (i) if an authorization is obtained from the Central Bank on the basis of
an existing "justified cause" which allows the prepayment;
 
     (ii) if the substitution of foreign currency indebtedness agreements with
other foreign currency indebtedness agreements or through the issuance and
placement of securities in international capital markets, provided such other
foreign currency indebtedness agreements or securities have a term greater than
36 months;
 
     (iii) if the mandatory prepayment arises pursuant to a foreign indebtedness
agreement incurred to finance a private project through a BOT (build, operate
and transfer), BOM (build, operate and manage), BOMT (build, operate, manage and
transfer), BOOM (build, own, operate and manage) or any similar agreement in the
event of (a) the early termination of such agreement, (b) the total or partial
loss of the assets of the project such that its continuation is no longer
economical or (c) the expropriation of assets or goods of the project;
 
     (iv) if prepayment is made after half of the agreed term for payment has
elapsed with the proceeds of a foreign investment obtained through (a) placement
of ADRs or BOCEAS of Colombian companies or (b) capitalization of external debt
through acquisition of shares of the debtor company; or
 
     (v) if the prepayment relates to indebtedness that was recorded without
having made a previous deposit or if the terms of the indebtedness has a term of
36 months or less.
 
     There can be no assurance that the deposit requirements of Resolution 21,
as amended by Resolution 005, 1996, will not be amended or that additional
foreign exchange controls which are applicable to the Notes will not be enacted.

                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver this Prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer who
holds Old Notes acquired for its own account as a result of market-making
activities or other trading activities (a "Participating Broker-Dealer") in
connection with resales of New Notes received in exchange for Old Notes. For a
period of 180 days after the Expiration Date, the Company will make this
Prospectus, amended or supplemented, available to any Participating
Broker-Dealer for use in connection with any such resale, provided that such
Participating Broker-Dealer indicates in the Letter of Transmittal that it is a
broker-dealer. In addition, until             , 1996, (90 days after the date of
this Prospectus), all dealers affecting transactions in the New Notes may be
required to deliver a prospectus.
 
     The Company will not receive any proceeds from the exchange of Old Notes
for New Notes by broker-dealers. New Notes received by broker-dealers for their
own account pursuant to the Exchange Offer may be sold from time to time in one
or more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Notes or a combination of such methods
of resale, at market prices prevailing at the time of resale, or at prices
related to such prevailing market prices or at negotiated prices. Any such
resale may be made directly to purchasers or to or through broker-dealers who
may receive compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any New Notes. Any broker-dealer that
resells New Notes that were received by it for its own account pursuant to the
Exchange Offer and any person that participates in the distribution of such New
Notes may be deemed an "underwriter" within the meaning of the Securities Act
and any profit on any such resale of New Notes and any commissions or
concessions received by any such broker-dealers may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
 
     For a period of 180 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any Participating Broker-Dealer that requests
such documents in the Letter of Transmittal. The Company has agreed to pay all
expenses incident to the Exchange Offer other than commissions or concessions of
any broker-dealers and will indemnify the holders of the Old Notes (including
Participating Broker-Dealers) participating in the Exchange Offer against
certain liabilities, including liabilities under the Securities Act.
 
     By acceptance of this Exchange Offer, each broker-dealer that receives New
Notes pursuant to the Exchange Offer agrees that, upon receipt of notice from
the Company of the happening of any event which makes any statement in this
Prospectus untrue in any material respect or which requires the making of any
changes in this Prospectus in order to make the statements therein not
misleading (which notice the Company agrees to deliver promptly to such
broker-dealer), such broker-dealer will suspend use of this Prospectus until the
Company has amended or supplemented this Prospectus to correct such misstatement
or omission and has furnished copies of the amended or supplemented Prospectus
to such broker-dealer. If the Company gives any such notice to suspend the use
of the Prospectus, it will extend the 180-day period referred to above by the
number of days during the period from and including the date of the giving of
such notice up to and including when broker-dealers shall have received copies
of the supplemented or amended Prospectus necessary to permit resales of New
Notes.

                  ENFORCEMENT OF FOREIGN JUDGMENTS IN COLOMBIA
 
     The courts of Colombia give effect to and enforce judgments obtained in
non-Colombian courts through a process provided for under Colombian law known as
exequatur, subject to the provisions of Articles 693 through 695 of the
Colombian Code of Civil Procedure (Codigo de Procedimiento Civil). Such articles
provide for enforcement by Colombian courts of foreign judgments which are
obtained without fraud and rendered after due notice, provided that either (a)
Colombia and the country where the foreign judgment has been issued are parties
to a treaty which recognized the enforceability of foreign judgments or (b) a
judgment rendered by a court of Colombia would be enforceable on a reciprocal
basis in the country where such foreign judgment is obtained, and that the
foreign judgment (i) does not relate to "in rem" rights vested in assets that
were located in Colombia at the time the suit was filed, (ii) does not
contravene any public policy laws or regulations of Colombia, other than those
governing judicial procedures, (iii) is a final judgment not subject to appeal
in accordance with the applicable foreign laws and an original certified copy of
such judgment is filed with the court, (iv) does not refer to any matter upon
which Colombian courts have exclusive jurisdiction, (v) does not refer to any
matter subject to a lawsuit presently ongoing in Colombia or already decided by
any court of Colombia, (vi) was obtained upon complying with the applicable
foreign laws relating to service of process to the defendant, which compliance
is presumed if the judgment is final, and (vii) be submitted to the exequatur
procedure before the Supreme Court of Colombia, which requires that the party
proposing to enforce the foreign judgment give prior judicial notice to any
person or entity that may be affected by the judgment.
 
     Of those requirements imposed by the Colombian Code of Civil Procedure, the
two issues which are most likely to generate controversy in exequatur
proceedings are (i) whether there exists an applicable treaty or reciprocity
between the two countries, as described in the previous paragraph and (ii)
whether the foreign judgment contravenes Colombia's public policy laws and
regulations. Occel has been advised by its Corporate Secretary General and
Administrative Vice President that the United States and Colombia do not have a
treaty providing for reciprocal recognition and enforcement of judgments in
civil and commercial matters; however, there is a precedent (a ruling issued on
July 19, 1994) in which the Supreme Court of Colombia recognized the existence
of such reciprocity based upon (i) evidence that a court in the State of Florida
had accepted the validity of a Colombian judgment in a certain case and (ii)
declarations by the United States lawyers acting as expert witnesses to the
effect that courts in the State of Florida had enforced judgments issued in
Latin American countries other than Colombia and that judgments issued by
Colombian courts would be enforced under the same principles. The Company can
provide no assurance, however, that this interpretation will prevail in future
exequatur proceedings. The Company does not believe, in the case of the Notes,
that a foreign judgment ordering the payment of money would conflict with any of
Colombia's current public policy laws or regulations.
 
     The Company has been advised by its Corporate Secretary General and
Administrative Vice President that there can be no assurance as to the
enforceability, in original actions in Colombian courts, of liabilities
predicated solely on the United States federal or other non-Colombian securities
laws.
 
                                 LEGAL MATTERS

de Bogota, Colombia, and Mauricio Campillo-Orozco, Medellin, Colombia, with

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
Occidente y Caribe Celular S.A.:
 
     We have audited the accompanying balance sheets of Occidente y Caribe
Celular S.A. as of December 31, 1995 and 1994, and the related statements of
income (loss), shareholders' equity, cash flows and changes in financial
position for each of the years in the three-year period ended December 31, 1995.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards in Colombia. Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Occidente y Caribe Celular
S.A. as of December 31, 1995 and 1994, and the results of its operations, cash
flows and changes in its financial position for each of the years in the
three-year period ended December 31, 1995, in conformity with generally accepted
accounting principles in Colombia.
 
     Generally accepted accounting principles in Colombia vary in certain
significant respects from generally accepted accounting principles in the United
States. Application of generally accepted accounting principles in the United
States would have affected results of operations for each of the years in the
three-year period ended December 31, 1995 and shareholders' equity as of
December 31, 1995 and 1994, to the extent summarized in note 17 to the financial
statements.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1994 AND 1995
              (EXPRESSED IN MILLIONS OF CONSTANT COLOMBIAN PESOS)
 
(1)  OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES
 
  Operations
 
     Occidente y Caribe Celular S.A. (the Company or Occel) is a mixed economy
company (owned by public and private sector shareholders) established under
public deed No. 378 dated February 14, 1992 of the only Notary in Soledad
(Atlantic Department). The Company was incorporated for a period ending on
December 31, 2092.
 
     The Company provides mobile cellular telephone and other related
telecommunication services in the western region of Colombia (the "Western
Region") pursuant to a ten-year concession, subject to renewal for an additional
10 years (the "Concession"), awarded under contract No. 000005 dated March 28,
1994 by the Ministry of Communications.
 
     Cellular operators typically experience losses and negative cash flow in
their initial years of operation due to the large capital investments required
for construction of their networks and the significant advertising and other
expenses needed to start the business. Consistent with this pattern, the Company
has incurred cumulative losses and negative cash flows from operations since
September 1, 1994. In addition, the Company has accumulated a significant
working capital deficiency due to these factors as well as the scheduled
maturities of its notes payable and long-term debt. The Company is currently
pursuing a debt offering and new banking facility which will enable the Company
to repay substantially all its existing indebtedness and fund its working
capital and capital expenditure needs. Should this plan not succeed, the Company
would be dependent upon capital contributions from its shareholders or other
financing in order to fund any working capital deficiencies and capital
expenditures. (See note 18 -- Subsequent event -- unaudited.)
 
  Financial statements
 
     During 1992, 1993 and through August 31, 1994, the Company was a
development stage enterprise. The financial statements for 1994 and 1993,
provided herein, reflect the results for such pre-operating period. Results for
the year ended December 31, 1994 may not be comparable as the Company commenced
commercial operations in September 1994. The financial statements as of March
31, 1995 and 1996 and for the three months ended March 31, 1995 and 1996 are
unaudited. In the opinion of management the interim financial statements include
all material adjustments (consisting only of adjustments of a normal and
recurring nature) necessary for a fair presentation of the results for such
periods. The results of operations for any interim period are not necessarily
indicative of the results of operations for a full year.
 
  Convenience translation (unaudited)
 
     For the convenience of the reader, the financial statements of the Company
contain translations of certain Colombian peso amounts into US dollars at the
March 31, 1996 exchange rate of 1,046.00 pesos per US dollar, the rate reported
by the Superintendency of Banking. No representation is made that the Colombian
peso amounts have been, could have been, or could be converted into US dollars
at such a rate or any other rates.
 
  Significant accounting principles
 
     (A) INFLATION ACCOUNTING
 
     Financial statements are adjusted for the effects of inflation on the basis
of changes in the official Colombian middle-income Consumer Price Index ("CPI")
established by the National Administrative Statistics Department. This index is
applied, on a one-month lagging basis, to non-monetary assets and liabilities,
shareholders' equity and revenue and expense accounts. Monetary balances are not
adjusted because they reflect purchasing power of the currency as of the balance
sheet date. Foreign currency balances are not adjusted since they are translated
into Colombian pesos as of the date of the balance sheet and, consequently,
reflect the purchasing power of the currency on that date.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The resulting net gain or loss from exposure to inflation is reflected as
"Net Monetary Correction" in the statements of operations. Accordingly, the "Net
Monetary Correction" reflected in the statements of operations of the Company is
the result of netting or offsetting the following items:
 
     - a credit for inflation affecting non-monetary assets;
 
     - a charge for inflation affecting non-monetary liabilities and
       shareholders' equity; and
 
     - charges and credits representing inflation adjustments made to revenue
       and expense items, respectively. Such adjustments are included within the
       individual expense and income captions in the statements of operations.
 
     Since monetary inflation adjustments contained within the individual
expense and income captions are offset in the Net Monetary Correction account in
the statements of operations, the net effect on net income or loss from the
expense and income inflation adjustments is zero. Therefore, the only impact on
the statements of operations of the effects of inflation is attributable to the
restatement of non-monetary assets, liabilities and shareholders' equity
accounts.
 
     Unless expressly stated otherwise, the financial information included in
the accompanying financial statements and notes thereto for all periods
presented has been restated into constant Colombian pesos as of March 31, 1996
in order to express all financial information in purchasing power as of that
date. The rate of inflation and the CPI factor applied to the Company's nominal
financial statements data for each period is as follows:

     (b) CASH AND CASH EQUIVALENTS
 
     Short-term investments with original maturities of three months or less are
considered cash equivalents for the purposes of the cash flow statements due to
their high liquidity.
 
     (c) INVENTORIES
 
     Inventories primarily consist of telephones and accessories and are
recorded at the lower of average cost or market, adjusted for inflation.
 
     (d) PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment are recorded at cost, adjusted for inflation.
Depreciation is calculated on the straight-line method over the estimated useful
lives of the assets, as follows:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     (e) INTANGIBLE ASSET
 
     Intangible asset corresponds to the acquisition cost of the Concession to
provide cellular mobile telephone service in the Western region of Colombia and
is recorded at inflation-adjusted cost less accumulated amortization. The
Concession cost is amortized over nine years and seven months from September
1994, the start date of the Company's commercial operations, based on the units
of activation method. To calculate the monthly amortization charge, this method
utilizes the sum of the projected subscribers per month for each month during
the term of the Concession as the denominator and the sum of the subscribers per
month for each month in the reporting period as the numerator. The Company will
revise the underlying projections of subscribers on a periodic basis, and any
resulting impact on amortization expense will be accounted for in subsequent
periods.
 
     (f) DEFERRED CHARGES
 
     Deferred charges consist of organization and preoperating expense, deferred
monetary correction, software and leasehold improvements.
 
     Costs and expenses incurred during the preoperating period are amortized by
the straight-line method over five years starting September 1, 1994, the start
date of the Company's commercial operations.
 
     Deferred monetary correction represents the inflation adjustments on the
Company's non-monetary assets and equity during the preoperating phase, i.e.,
through August 31, 1994. The amounts are amortized over the life of the
Concession using the same method for amortization as that used for intangible
assets.
 
     Purchased software is amortized over three years. Leasehold improvements
are amortized over the life of the rental agreement.
 
     (g) ASSET REVALUATIONS
 
     In addition to inflation adjustments, changes in the market value of
property, plant and equipment, for reasons other than inflation, are recorded
periodically. Positive revaluations related to inflation-adjusted net book value
are recorded in compensating balance sheet accounts which are shown in the asset
caption and the shareholders' equity caption "Revaluations". Should a
devaluation result, a provision is made in the statement of income (loss) and
the value of the asset is reduced.
 
     Revaluations of assets must be made and recorded whenever management
becomes aware of a material difference between the market value and the
inflation-adjusted net book value of the assets. The revaluations are based on
the difference between technical appraisals of the replacement costs of such
assets and the respective inflation-adjusted net book values. Such appraisals
should be made every three years. As the Company commenced operations in 1994,
no appraisal has yet been made.
 
     (h) FOREIGN CURRENCY TRANSACTIONS
 
     Foreign currency transactions and balances denominated in a currency other
than Colombian pesos are translated monthly into Colombian pesos at market rates
certified by the Banking Superintendency. The exchange rate used to adjust the
resulting balance in US dollars at December 31, 1993, 1994 and 1995 was
Ps804.33, Ps831.60 and Ps987.65 per US$1.00, respectively. The resulting
difference is charged or credited to the statement of income (loss).
 
     (i) RELATED PARTIES
 
     The Company classifies any balances and transactions with its affiliates
and principal owners as related party transactions.

     (j) REVENUE RECOGNITION
 
     Cellular service revenues based upon subscriber usage and access and
special feature cellular service revenues are recognized at the time the service
is provided. Equipment sales are recognized at the time equipment is delivered
to the subscriber or to an agent.
 
     (k) LEASE PAYMENTS
 
     Lease payments are recorded as an expense. The total liability under lease
contracts is recorded in the memorandum accounts. The leased asset is only
booked when the purchase option is exercised.
 
     (l) INCOME TAX
 
     Effective from 1996, according to Law 223 of December 20, 1995, the Company
is liable for income tax at a statutory tax rate of 35%. Before this change in
the law, the Company was not liable for income tax and, therefore, no provision
has been recorded for income taxes. Fiscal losses may be carried forward for tax
purposes for five years. In 1996 and future years, the Company's tax liability
will be calculated on the greater of (i) net taxable income and (ii) presumed
income, which is the greater of 5% of shareholders' fiscal equity or 1.5% of
total assets, in each case at the beginning of the taxable year.
 
     (m) NET INCOME (LOSS) PER SHARE
 
     Net income (loss) per share is computed by dividing net income (loss) by
the weighted average number of common shares outstanding during each year
presented.
 
     (n) USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
(2)  CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with original maturity
of three months or less to be cash equivalents. Substantially all of the
Company's cash and cash equivalents are denominated in Colombian Pesos. A
summary follows:

     The Concession consists of the right to establish and develop a cellular
telephone communications business in the western region over a 10-year period in
exchange for a one-time concession fee, combined with quarterly royalty payments
in the amount of 5% of adjusted gross revenues to the Ministry of Communications
for the use of the cellular frequencies. The Company was awarded the Concession
in a competitive bidding process, based upon not only the price offered by the
Company, but also the technical capabilities and operational capacity, the
mobile cellular experience of its affiliates, and its financial and planning
capability. The Concession commenced March 28, 1994 and may be renewed for an
additional 10-year term. The purchase price for the Concession was Ps 123.1
billion (actual pesos). The Concession may not be assigned during the first
three years from the date of signing. However, once this period has elapsed, it
may be assigned subject to authorization by the Ministry of Communications. At
the end of the Concession's term, those Company assets that are directly related
to the Concession are to revert to the Ministry of Communications without
compensation.

</TABLE>
 
     Deferred monetary correction represents the inflation adjustment on the
portion of the Company's shareholders' equity used to finance the Concession,
deferred charges and construction in progress. Since debt is a monetary
liability, no inflation adjustment is required, however, since shareholders'
equity is non-monetary, inflation adjustments are applied. Such resulting
charges were capitalized during the preoperating period and are amortized using
the same method for amortization or depreciation as that used for the respective
asset.

     A guaranty trust was set up to serve as the main guaranty for the Company's
financing obligations. The trust was set up by eleven trust companies, all of
them subsidiaries of Occel's lender banks. To facilitate the operation of the
trust, one of the trust companies was appointed by the others to serve as a
leader and administrator of the trust.
 
     The value of the trust is 70% of the net present value of the revenues of
the Company for the first 10 years of operations. The value of the trust is
revised every six months. The value of the trust is divided proportionally among
all the participating trust companies; each company issues certificates of
guarantee as requested. When Occel arranges a loan, both Occel and the creditor
bank, request the leader of the trust for the issuance of a certificate of
guaranty in the name of the creditor bank. The leader selects in turn, one trust
company to issue such certificate. The certificate is issued in the same amount
of the loan. The difference between the value of the trust and the total of the
certificates issued is available for the issuance of more certificates if
needed.
 
     Additionally, US$50,000,000 are guaranteed by certain Colombian banks
including certain indirect shareholders of the Company and are backed by assets
of the trust.

(12) SHAREHOLDERS' EQUITY
 
     On September 5, 1995 the Shareholders increased the authorized capital to
Ps 91,964, representing 91,964,254 shares, with a nominal value of one thousand
pesos each.
 
     In accordance with current regulations, the Company is required to maintain
a legal reserve, setting aside a minimum of 10% of net income each year until
the reserve reaches 50% of the subscribed capital. Amounts appropriated to legal
reserve cannot be reduced below 50% of the subscribed capital unless they are
applied to losses in excess of retained earnings.
 
     In accordance with exchange control provisions in effect, there is no limit
on dividend remittances abroad. Article 133 of the law 6 of 1992 established a
rate of 10% withholding at source on remittance of dividends or equity earned by
companies or other foreign entities without a domicile in the country. This rate
was effective through 1994, decreased to 8% for 1995 and will be reduced to 7%
for 1996 and thereafter.

(14) COMMITMENTS AND CONTINGENCIES
 
     The Company has agreements with telephone companies in the Western Region
of the Country which establish the technical, operative, administrative,
economic, financial and judicial rights and obligations that regulate the access
and use of the public switched telephone and the cellular mobile telephone
networks, as well as the billing and collection conditions.
 
     The Company signed a letter of intent to enter into an interconnection
agreement in 1995 with the "Empresa Nacional de Telecomunicaciones-Telecom".
Such letter of intent includes provisions for the number of connection points,
the method by which signals must be received and transmitted, fraud control,
billing, damage liability and the assumption of responsibility for the costs of
interconnection.
 
     The Company has signed financial leasing agreements with purchase options
for the acquisition of base stations, microwave links and vehicles, with
maturities up to the year 2000. The minimum leasing payments as of December 31,
1995 are as follows:

     On August 17, 1994, the municipality of Medellin through Resolution No. 019
imposed a monthly tax on cellular subscribers (the "Cellular Services Tax")
whose calls use base stations located in Medellin. Subsequently, the mayor of
Medellin, on January 23, 1995, regulated the billing and collection of this tax
through Municipal Decree 1244 (the "Decree"), which imposed upon the two
cellular operators of the Western Region the obligation to, in each of their
billing systems, determine, bill, collect and transfer this tax. Both
regulations have been challenged in court by the Company on the grounds of not
being consistent and in conformity with current higher ranking law. Medellin's
tax authorities through Resolution No. 005, issued on March 6, 1996, determined
that Occel's transfer obligation under the Decree, together with interest, for
the period through October 31, 1995 was Ps 317 million (US$303,000). The Company
appealed this determination on March 14, 1996, and a decision is still pending.
Occel has not collected the Cellular Services Tax from its customers because it
believes that the tax is illegal and that the challenges against Resolution No.
019 and the Decree will be successful and, consequently, Resolution No. 005 will
not be upheld. In the event of an unfavorable decision, the Company believes
that it would be able to collect from its registered customers a portion of the
Cellular Services Taxes. At December 31, 1995 the Company recorded Ps 329
million

(US$315,000), excluding interest, as accounts receivable and accrued expenses.
No provision has been made for any amounts that may not be recoverable from
customers.
 
     When the proposal for the Concession was presented to the Ministry of
Communications, "A" Band cellular operators, including Occel, were not subject
to income taxes. However, as mentioned in note 1(l), "A" Band cellular operators
are now subject to income taxes. As this affects the economic return on the
Concession, the Company has filed a claim against the Ministry of
Communications. Should this claim not be accepted by the Ministry, or should the
Ministry not recognize an adequate compensation, the Company will go to an
arbitration tribunal as established under the Concession. There is no income tax
liability for 1995 or earlier years. The Company's net losses may be carried
forward for five years.

     During the preoperating period, the inflationary effect calculated on
intangible assets and deferred charges was recorded as a deferred credit for
monetary correction, and the inflationary effect arising from the adjustment to
shareholders' equity that financed such assets was recorded as a deferred charge
for monetary correction. Deferred balances are amortized using the same method
as for the Concession. Starting in September, 1994, when the Company commenced
operations, all inflationary effects are recognized as monetary correction in
the statements of income (loss).

     In January and February 1996, the shareholders subscribed and paid for Ps
13,000 (12,999,999 shares) of additional common stock.
 
(17)  SUMMARY OF THE SIGNIFICANT DIFFERENCES BETWEEN COLOMBIAN AND UNITED STATES
ACCOUNTING PRINCIPLES
 
     The Company's financial statements are prepared in accordance with
Colombian generally accepted accounting principles (Colombian GAAP), which
differ in certain significant respects from accounting principles generally
accepted in the United States (U.S. GAAP) as described below. The effects of
inflation adjustments have not been eliminated in the reconciliation to U.S.
GAAP nor has the Company reflected monetary gains or losses associated with the
various U.S. GAAP adjustments.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     (a) CAPITALIZED INTEREST
 
     Under Colombian GAAP, interest was not capitalized relating to the
construction of buildings as there were no loans specifically related to the
buildings.
 
     Under U.S. GAAP, in accordance with the provisions of SFAS 34, interest
incurred on borrowings is capitalized to extent that borrowings do not exceed
construction in progress. Such treatment increases the amount capitalized and
reduces interest expense. Additionally, the U.S. GAAP interest expense
adjustment excludes foreign exchange gains and losses on foreign currency
borrowings.
 
     (b) CAPITAL LEASES
 
     Under Colombian GAAP, lease payments are recorded as an expense. The total
liability under lease contracts is recorded in memorandum accounts. The leased
asset is only booked when the purchase option is exercised.
 
     Under U.S. GAAP, equipment under capital leases is recorded as an asset and
a liability is recorded for the present value of minimum lease payments at the
inception of the lease. This equipment is depreciated over the estimated useful
life of the asset.
 
     (c) INTANGIBLE ASSETS
 
     Under Colombian GAAP, the intangible asset, consisting of the Concession,
is amortized over the life of the Concession using the units of activation
method. Under U.S. GAAP, amortization is calculated over the life of the
Concession using the straight-line method.
 
     (d) PREOPERATING EXPENSES
 
     Under Colombian GAAP, preoperating expenses are capitalized during the
preoperating period and amortized when commercial operations begin. Under U.S.
GAAP such costs would be expensed as incurred.
 
     (e) DEFERRED CHARGES AND CREDITS FOR MONETARY CORRECTION
 
     In accordance with Colombian GAAP for inflation accounting, the effects of
inflation on preoperating activities, construction in process and the respective
portion of shareholders' equity used to finance such charges are deferred and
amortized over the life of the related assets when the Company becomes
operational.
 
     Under U.S. GAAP, such amounts may not be deferred. Accordingly, they are
expensed when incurred and the related amortization is reversed and financial
statements are prepared in accordance with the historical cost convention.
 
     (f) EFFECT IN REVALUATION OF SHAREHOLDERS' EQUITY
 
     This adjustment gives effect to the revaluation of shareholders' equity
arising from the above reconciling items.
 
ADDITIONAL DISCLOSURES REQUIRED BY U.S. GAAP
 
  CONCENTRATION OF CREDIT RISK
 
     Financial instruments which potentially subject the Company to
concentration of credit risk consist principally of accounts receivable
resulting from customer financing plans and other receivables from customers and
distributors. Concentration of credit risk with respect to such receivables is
limited to a large number of customers comprising the Company's customer base.
However, the Company's customers are concentrated in Colombia and the ability of
the customers to pay amounts due depends, in part, upon the

general condition of the Colombian economy. Generally, the Company does not
require collateral or other security to support receivables.
 
  ACCOUNTING FOR IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE
DISPOSED OF
 
     Effective for fiscal years beginning after December 15, 1995 SFAS No. 121
requires that long-lived assets and certain identifiable intangibles held by an
entity be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. The
Company has determined that adoption of SFAS 121 will not have any material
impact on Occel's financial position or results of operations.
 
  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     Cash and cash equivalents, trade and other receivables and accounts
payables: the carrying amount approximates fair value because of the short
maturity of these instruments.
 
     Long and short-term debt: the carrying amounts of the Company's variable
rate borrowings under its credit agreements approximate their fair value. The
fair value of the Company's fixed rate debt is estimated using discounted cash
flow analyses, based on the Company's current incremental borrowing rates.
 
     The carrying amounts and fair values of the Company's financial instruments
at December 31, 1995 are as follows:

(18) SUBSEQUENT EVENT (UNAUDITED)
 
     On June 7, 1996, pursuant to an offering of 190,745 units each of which
consisted of US$1,000 principal amount at maturity of 14% Senior Discount Notes
due 2004 and four warrants to purchase 5.709 shares of Class B common stock, the
Company raised US$100.0 million (gross proceeds). Concurrently with the issuance
of the units, the Company borrowed US$80.0 million under a bank facility, which
loans are secured by security interests in, among other things, (i) all
receivables originated from the provision of cellular communications and roaming
and interconnection services, (ii) the pledge of 99.99% of the Company's
outstanding stock and (iii) the Concession. The aggregate net proceeds of the
Offering and the borrowings under the Bank Facility were US$171.5 million. Such
net proceeds were used to repay substantially all existing indebtedness of the
Company and for working capital.

active subscribers:                         Reported subscribers currently generating
                                            revenue, which consist of reported subscribers
                                            minus disconnected subscribers.

Analog:                                     A transmission method employing a continuous
                                            electrical signal that varies in amplitude or
                                            frequency in response to changes in sound, light,
                                            position, etc., impressed on transducer in the
                                            sending device.

Band:                                       A range of frequencies between two defined
                                            limits.

Bandwidth:                                  The relative range of frequencies that can be
                                            passed through a transmission medium without
                                            distortion. The greater the bandwidth, the
                                            greater the information carrying capacity.
                                            Bandwidth is measured in hertz.

Base Station:                               In mobile telecommunications, the central radio
                                            transmitter/receiver that maintains
                                            communications with the cellular telephone sets
                                            within a given cell. Each cell or microcell has
                                            its own base station; each base station in turn
                                            is interconnected with other cells' base stations
                                            and with the public switched telephone network.

CDMA:                                       Code Division Multiple Access, a standard of
                                            digital cellular technology which allows for
                                            multiple conversations to be transported on a
                                            single radio carrier using digital "tags".
                                            Systems using this standard have not been placed
                                            into widespread commercial use.

Cell Site:                                  The location of a transmitting/receiving station
                                            serving a given geographic area in a cellular
                                            communications system.

Channel:                                    A pathway for the transmission of information
                                            between a sending point and a receiving point.

Churn:                                      Monthly disconnections expressed as a percentage
                                            of active subscribers at the beginning of the
                                            month.

Covered pops:                               The number of pops in a defined area for whom a
                                            cellular signal is accessible.

                                            referred to the legal area for account
                                            settlement. These subscribers are no longer
                                            included in the total of reported subscribers.

Digital:                                    A method of storing, processing and transmitting
                                            information through the use of distinct
                                            electronic or optical pulses that represent the
                                            binary digits 0 and 1. Digital transmission and
                                            switching technologies employ a sequence of
                                            discrete, distinct pulses to represent
                                            information, as opposed to the continuous analog
                                            signal.

Hand-off:                                   The act of switching a call in progress from one
                                            weak-signal site to a strong-signal site without
                                            disrupting the call. In current cellular systems,
                                            this function is performed by the MTSO, which
                                            monitors the signal strength of ongoing calls
                                            continuously. In cellular networks, both the MTSO
                                            and the user's equipment participate in the
                                            hand-off process.

Hertz:                                      The unit measuring the frequency with which an
                                            alternating electromagnetic signal cycles between
                                            its lowest and highest states. One hertz
                                            (abbreviated Hz) equals one cycle per second. kHz
                                            (kilohertz) stands for thousands of hertz; MHz
                                            (megahertz) stands for millions of hertz and hz
                                            (gigahertz) stands for billions of hertz.

Microwave:                                  The radio band transmission between 300 MHz -- 32
                                            hz.

Microwave Hop:                              The basic microwave transmission path (link),
                                            constituted by a couple of
                                            transmitters/receivers. The microwave frequency
                                            band requires "line of sight" between the two
                                            sides of the hop. Depending on the distance and
                                            topographical conditions, more than one "hop"
                                            could be necessary to establish a complete
                                            microwave transmission link.

MTSO:                                       Mobile Telephone Switching Office; the computer-
                                            controlled MTSO selects the appropriate path for
                                            the transmission of a cellular call and monitors
                                            the hand-off process. The MTSO allows cellular
                                            telephone users to move freely from one cell to
                                            another across the service area while continuing

Penetration:                                A cellular operator's subscribers within a
                                            defined area divided by total pops within that
                                            area. Colombian figures are based on reported,
                                            not active, subscribers. Penetration rates for
                                            countries other than Colombia are based on
                                            publicly available figures, which may calculate
                                            subscribers differently than in Colombia.

pops:                                       pops is the established population of the market
                                            and it is currently the most common technique for
                                            the measuring the relative size of a cellular
                                            telecommunications business.

PSTN:                                       Public Switched Telephone Network.

REDCEL:                                     A national cellular association composed of the A
                                            Band operators in the Western, Eastern and
                                            Atlantic Regions to enable their respective
                                            subscribers to make calls throughout the country
                                            and to enhance their competitive position.

reported subscribers:                       The subscribers as reported by the Company to the
                                            Colombian Ministry of Communications. Prior to
                                            September 1995, in accordance with the reporting
                                            guidelines of the Ministry of Communications, the
                                            Company filed quarterly reports which did not
                                            cover calendar quarters, but lagged by
                                            approximately one month. For purposes of
                                            consistency, reported subscribers set forth
                                            herein for periods prior to September 1995 have
                                            been calculated to conform to calendar quarters.
                                            Consistent with the Company's interpretation of
                                            the Ministry's reporting guidelines and with what
                                            the Company believes to be the common
                                            interpretation of cellular operators in Colombia,
                                            the Company currently includes in such term
                                            subscribers who have been temporarily
                                            disconnected and are under evaluation by the
                                            Company for reconnection or permanent
                                            deactivation. Prior to September 1995, reported
                                            subscribers also included permanently deactivated
                                            subscribers.

Repeater:                                   A device which automatically retransmits received
                                            signals on an outbound circuit, generally in an
                                            amplified form.

Roaming:                                    A service offered by mobile communications
                                            providers which allows a subscriber to use his or
                                            her cellular telephone while in the service area
                                            of another carrier.

Site or Cell Splitting                      The process of dividing sites or cells into
  or Sectorization:                         smaller coverage areas by reducing their power
                                            output and the antenna height of the station
                                            transmitter. Site or cell splitting (or
                                            sectoring) allows for the further reuse of
                                            frequencies by a mobile communications system.

Switch:                                     A device that opens or closes circuits or selects
                                            the paths or circuits to be used for transmission
                                            of information. Switching is the process of
                                            interconnecting circuits to form a transmission
                                            path between users.

TDMA:                                       Time Division Multiple Access, like AMPS, divides
                                            the radio spectrum into 30 kHz channels. The
                                            distinguishing feature of TDMA is it employs
                                            digital techniques at the base station and in the
                                            cellular radio to subdivide each channel into
                                            time slots which can be assigned to different
                                            users. Voice, data and access information are
                                            converted to digital information that is sent and
                                            received in bursts over the time slots. These
                                            bursts can be encoded, transmitted and decoded in
                                            a fraction of the time required to produce sound.
                                            The result is that only a fraction of the air
                                            time is used, and other subscribers can use the
                                            remaining time on a radio channel. Current IS-54
                                            TDMA technology allows three subscribers to share
                                            one channel without interference. With improved
                                            compression techniques, six subscribers could
                                            share a channel.

                              REPUBLIC OF COLOMBIA
 
A.  OVERVIEW
 
     Since 1950, Colombia has enjoyed positive real economic growth in every
year (ranging from a low of 0.95% in 1982 to a high of 8.47% in 1978) and
relatively stable rates of inflation (with a low of 2.2% in 1955 and a high of
32.6% in 1963). Inflation (as measured by the Colombian consumer price index
("CPI")) averaged 25.9% between 1990 and 1994. Unlike other major Latin American
countries, Colombia was not forced to restructure its debt with foreign
creditors during the 1980s, and instead entered into voluntarily syndicated loan
agreements to refinance certain maturities of its commercial bank debt. During
the same period, Colombia maintained access to new borrowings through
multilateral and bilateral credits. Colombia has regularly paid all principal
and interest payments on its external debt for over 60 years.
 
     Former President Cesar Gaviria, upon taking office in August 1990,
introduced a program called Apertura (opening), designed to transform the
economy from a relatively protected one to a modern, open economy, and to
redefine the government's role in the economy. Under Apertura, the government,
among other measures:
 
     - Removed restrictions on foreign investment generally, and eliminated
       restrictions on remittances of capital and dividends;
 
     - Eliminated import quotas and, during the 1989-1994 period, reduced
       tariffs from an average effective rate of 43.7% to 11.6% and entered into
       free trade agreements with Venezuela and some of its other regional
       trading partners;
 
     - Granted greater independence to Banco de la Republica, the country's
       central bank;
 
     - Reduced foreign exchange controls;
 
     - Began to liberalize labor laws, permitting greater flexibility in labor
       contracts and eliminating restrictions on severance and furloughs of
       workers, and partially privatized the pension system; and
 
     - Undertook a program of privatizing certain state-owned companies and
       financial institutions.
 
     Under the Samper administration, the Apertura has been modified, and
investors should consult other sources for an evaluation of the success of the
program to date.
 
GEOGRAPHY
 
     Colombia is the fourth largest country in South America, with a territory
of 441,020 square miles (1,141,748 square kilometers). Located on the
northwestern corner of the South American continent, Colombia borders Panama and
the Caribbean Sea on the north, Peru and Ecuador on the south, Venezuela and
Brazil on the east and the Pacific Ocean on the west.

GOVERNMENT AND POLITICAL PARTIES
 
     The Republic of Colombia is one of the oldest democracies in the Americas,
with regular transitions of power between successive administrations since 1957.
The main political parties are the Liberal Party (to which President Samper
belongs) and the Partido Social Conservador. There are other minority parties,
including the Alianza Democratica M-19, a former guerrilla organization that
recently became a recognized political party.
 
     In 1991, a popularly elected Constitutional Assembly approved a new
Constitution, replacing the Constitution of 1886. The main features of the new
Constitution include further governmental decentralization, increased
Congressional powers and the creation of several new public agencies. A number
of judicial reforms were also introduced to improve the government's ability to
combat the guerrilla and narcotic-related violence, and to enhance control and
supervision over public officials.
 
B.  ECONOMY
 
GROSS DOMESTIC PRODUCT
 
     Traditionally, agriculture has played a large role in the Colombian
economy, accounting for an estimated 19.7% of GDP in 1994, compared to 20.0% of
GDP for industry. In 1994, agricultural activity increased by 2.0% in real terms
(despite a decrease in coffee production of 11.8%), industrial activity
increased by 2.8% (due to a 4.7% increase in manufacturing partly offset by an
11.7% decrease in coffee processing), construction increased by 11.8%, and
services increased by 8.3%. Between 1990 and 1994, GDP grew at an average annual
rate of 4.2%. Real GDP growth for 1994 was 5.7%, which was achieved despite
lower prices for commodities, especially oil.
 
     The following table sets forth the annual change in Colombia's real GDP by
sector for the periods indicated.

C.  MONETARY SYSTEM AND MONETARY AGGREGATES
 
     Banco de la Republica, Colombia's central bank, was chartered in 1923.
Following ratification of the new Constitution in 1991, Banco de la Republica
was granted greater independence from the government in the formulation of
monetary policy.
 
     Monetary and exchange rate policy is set by Banco de la Republica's Board
of Directors. The Board of Directors is composed of seven members, five of whom
are permanent members appointed by the President for four-year terms, although
at the expiration of their terms, the President may not replace more than two
such members. The Minister of Finance, the sixth member of the Board of
Directors, is the sole representative of the government on the Board of
Directors. The seventh member, who is the Governor of Banco de la Republica, is
elected by the other six members. Unless all seven members of the Board of
Directors vote to do so, Banco de la Republica may not finance the government's
budget deficits, and Banco de la Republica is prohibited from making loans to
the private sector (except to provide liquidity to the financial system or for
the intermediation of foreign indebtedness).

FOREIGN EXCHANGE RATES AND INTERNATIONAL RESERVES
 
     Colombia's official monetary unit is the peso, the value of which was
established against foreign currencies under a crawling peg system between 1967
and 1991. Under this system, the nominal exchange rate was determined by Banco
de la Republica.
 
     In February 1994, Banco de la Republica instituted a mechanism, which
consists of a 15% band within which the exchange rate is allowed to fluctuate.
Banco de la Republica intervenes by selling or purchasing its debt securities in
order to maintain the exchange rate within the 15% band. Such band is allowed to
depreciate by small amounts to meet an annual target devaluation rate.
 
     Foreign exchange transactions today occur at free, or market, exchange
rates. During 1994, the nominal exchange rate devalued by 3.6%, while
appreciating 8.9% in real terms.

SECURITIES MARKETS
 
     Colombia has three stock exchanges, one located in each of the cities of
Bogota, Medellin and Cali. The stock exchanges are owned by member firms that
are responsible for developing and implementing regulations governing trade on
their exchanges. Although self-regulating, they remain subject to the approval
and supervision of the Superintendency of Securities, the principal securities
market regulatory agency. According to the Superintendency of Securities, the
market capitalization of the three exchanges as of December 31, 1994 was US$18.5
billion, with an average daily value of shares traded during 1994 of US$11.6
million.
 
     The total value of securities traded on the three Colombian stock exchanges
during 1994 was Ps18,652 billion (approximately US$22.6 billion), representing
nominal growth of 75.4% over the value of securities traded in 1993. Both debt
and equity securities are traded on the three stock exchanges, including stocks
and bonds of private-sector corporations, although the vast majority of
securities traded are fixed income debt securities.
 
     At the end of 1994, over 216 stocks were listed on the three exchanges. In
October 1995, the five companies with most actively traded shares on the three
exchanges represented 29.9% of the total value of stocks traded on the three
exchanges.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Directors and officers are severally liable to the Company, the
shareholders and third parties for any damages they cause as a result of their
negligence or fraud in the execution of their duties. There is a presumption of
negligence in cases where they breach their duties or violate the law or by-laws
of the Company. Directors and officers also have criminal liability where they
mislead the authorities, provide false information or permit, tolerate, order or
cover up misinterpretations in the financial statements of the Company.
 
     Under Colombian law, the Company can indemnify its directors and officers
and purchase director and officer insurance. However, the Company's by-laws
currently do not provide for indemnification of directors or officers, and the
Company presently does not have any director and officer insurance in effect.

ITEM 22.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that:
 
     (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(b)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (3) Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant, will unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

     (4) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed to be underwriters, in addition to the information
called for by the other Items of the applicable form.
 
     (5) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (4) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

are examined. 4th) To receive a proportional part of the corporate assets at
the time of liquidation and once the external liabilities of the corporation

common and single representative who shall exercise the rights inherent to the
condition as shareholders. ARTICLE TWENTY-FOURTH - The corporation shall open
and keep a stock register ledger, where the provisional certificates as well as
the final certificates corresponding to the subscribed shares shall be
registered, and any transfers, establishment of rights or real guarantees on
such shares, judicial attachments and civil suits that may affect them shall be
noted. ARTICLE TWENTY-FIFTH - The pledge established on the certificate shall
not grant the guaranteed creditor the rights inherent to the condition as
shareholder, but by virtue of an express stipulation or agreement shall only

except as expressly provided otherwise, shall grant its beneficiary all rights
inherent to the condition as shareholder, except the right to dispose of and
encumber them and that of their reimbursement at the time of liquidation.
ARTICLE TWENTY-SIXTH - The shareholder must register at the corporate offices
their address and the place to which the notices and communications from the

restriction related to the right of preference hereinafter regulated, the
shares of the corporation are freely negotiable, and for this purpose only the
agreement by the contracting parties shall be sufficient; however, the
assignment shall not produce any effects in respect of the corporation or third
parties, but only after registration in the stock register, which shall be made
based on a written order by the assignor who may give it by means of a letter
of transfer or the endorsement of the relevant certificates. In order to make
the new registration and issue the certificate to the new holder,
<PAGE>   5
the prior cancellation of the certificates sold shall be required. Public
entities which are shareholders expressly waive their right of preference
provided by article 10 of Decree law 130 of 1976, but the right of preference
provided by the Commercial Code shall be admitted, whereby the shareholders have
the privilege of acquiring the shares that anyone intends to sell, all in
accordance with the procedure and regulations stated next: a) The shareholder
who intends to assign his shares shall immediately give notice to the
corporation, by means of a letter addressed to the President indicating the
price, term and all other conditions of the disposal. The notice is considered
duly informed when the letter has been delivered to the President, which shall
be evidenced by a receipt from him or other means of proof. b) The President
shall inform all shareholders of the offer of the shares, which may be purchased
by them proportionately to the number of shares owned by them. This preferential
right of purchase may be exercised by the shareholders within twenty (20)
business days following the communication given by the President. c) The shares
that are not the object of preferential right may be sold by the shareholder
subject to the price, term and all other conditions contained in the offer, but
the assignment shall be made within sixty (60) business days following the
expiration of the term that the shareholders had for the acceptance of the
offer; therefore, every transaction executed subsequently shall require the
repetition of the procedure provided by this article. d) The shareholders that
may have exercised the right of preference shall have the obligation to execute
the transaction; but if the conditions of the offer would seem to them very
onerous, they shall be entitled to request a revision of such conditions. The
decision shall be binding upon the parties, but they may previously agree that
the conditions of the offer shall prevail if those established by the experts
would turn out to be more unfavorable for the purchasers. The qualified
revisions shall be performed by three experts who may be appointed directly and
by mutual agreement by the parties or the latter may delegate the total or
partial designation to a third party. Notwithstanding the foregoing, the parties
may agree to designate only one expert. In lieu of an agreement for the
appointment of the expert or when the third party delegated does not make the
designation in the time indicated by the parties for this purpose, any one of
them may request the judge to require the party reluctant to reach an agreement,
or the third party, to carry out the designation. If any of the parties does not
attend the hearing scheduled by the judge or an agreement or the designation is
not reached, the Judge shall proceed to appoint the corresponding experts, from
the list of the Chamber of Commerce of Santafe de Bogota. The request must
contain a clear and summarized statement of the relevant facts. For the purposes
of this item, by party is understood to be the offering shareholder, on the one
side, and those who have exercised the right of preference, on the other. e) The
right of preference shall be applicable even through the transaction covered by
the intended disposal may not be a purchase or sale but a different one, such as
an exchange, a contribution to a corporation, or also a delivery as payment,
etc.; in addition, if the transaction

<PAGE>   6
that the offering party intends to perform with a third party, in the event
that the right of preference is not exercised, were an interchange or a
donation, the offerer shall in any event state in his offer to the corporation
and to the shareholders, the value in money for which he estimates his shares,
since the preferential acquisition shall always have as a basis a purchase/sale
transaction. The shares may be the object of attachment and compulsory
disposal, but in this event, because the right of preference is expressly
agreed, the shareholders may acquire them in the manner and term indicated in
the Commercial and Civil Procedure Code. g) The right of preference shall not
be applicable when the transfer of the shares is made by a method that excludes
it, such as from the estate of a deceased person and the liquidation of the
joint properties of a married couple. h) The right of preference shall not be
applied either when the General Stockholders Meeting authorized its non-
applicability for a specific case, by a majority representing seventy percent
(70%) of the subscribed shares of the corporation. i) The share certificates
shall make express mention of the right of preference and of the conditions
provided in order to exercise such right. j) While the statutory right of
preference exists, the corporation cannot register its shares in the stock
market. PARAGRAPH When entities of the solidary social sector wish to totally
or partially transfer Type C shares which they own, they must offer them in
first term to other entities of the same solidary social sector and only in the
event that after four (4) years from the first offer have elapsed and their
transfer has not been possible, may they transfer them to another person who
has a different quality than that of the solidary social sector. In this last
case, that is, after four (4) years have elapsed without effecting the transfer
of Type C shares on the part of the solidary entity or entities to other
entities of the same sector, the transfer of these shares must be effected by
offering them preferentially to the Corporation and to the Shareholders of the
Corporation pursuant to the terms and steps described in this article. These
shares shall change series depending on the quality of the Shareholders
acquiring them. ARTICLE TWENTY-EIGHT - The Corporation shall not refuse to make
the registration in the stock register except by order of a competent authority
and if it were the case of Type C shares, their inscription could be denied
when solidary social sector entities have not fulfilled the procedures
established in the previous article. ARTICLE TWENTY NINTH - The transfer of
provisional certificates shall be made following the regulations indicated by
this same regulation for the transfer of final certificates representative of
shares. But in such a case, the assignor and assignee shall be jointly liable
to the corporation for the unpaid value of the subscribed shares represented by
said provisional certificates. CHAPTER VI: DIRECTION AND MANAGEMENT OF THE

        INDENTURE, dated as of June 1, 1996, between Occidente y Caribe Celular
S.A., a sociedad anonima de economia mixta existing under the laws of the
Republic of Colombia (herein called the "Company"), having its principal office
at Calle 50 No. 55-01, Medellin, Colombia, and The Bank of New York, a New York
banking corporation, as Trustee (hereinafter called the "Trustee").


                            RECITALS OF THE COMPANY

        The Company has duly authorized the creation of an issue of 14% Senior
Discount Notes due 2004 (herein called the "Initial Securities") and 14% Series
B Senior Discount Notes due 2004 (the "Exchange Securities" and, together with
the Initial Securities, the "Securities"), of substantially the tenor and
amount hereinafter set forth, and to provide therefor the Company has duly
authorized the execution and delivery of this Indenture.

        Upon the issuance of the Exchange Securities, if any, or the 
effectiveness of the Shelf Registration Statement (as defined herein), this
Indenture will be subject to the provisions of the Trust Indenture Act of 1939,
as amended, that are required to be part of this Indenture and shall, to the
extent applicable, be governed by such provisions.

        Pursuant to the terms of a Purchase Agreement dated as of May 31, 1996
(the "Purchase Agreement") between the Company and Merrill Lynch, Pierce,
Fenner & Smith Incorporated and ING Baring (U.S.) Securities, Inc., as Initial
Purchasers (the "Initial Purchasers"), the Company has agreed to issue and sell
190,745 units (the "Units"), each Unit consisting of US$1,000 principal amount
of the Securities and four Warrants (each, a "Warrant") entitling the holder
thereof to purchase 5.709 shares of Class B Common Stock, par value 1,000
Pesos per share, of the Company from the Company at an exercise price of
US$1.00 per share, subject to adjustment as provided in the Warrant Agreement
dated as of the date hereof (the "Warrant Agreement") between the Company and
The Bank of New York, as warrant agent. The Securities and the Warrants will
become separately transferable on the earlier of (i) 90 days after issuance,
(ii) the occurrence of a Change of Control (as defined herein) and (iii) the
date on which the Exchange Offer Registration Statement (as defined herein) is
declared effective (the "Separation Date").

        All things necessary have been done to make the Securities, when
executed by the Company and authenticated and delivered hereunder and duly
issued by the Company, the valid obligations of the Company and to make this
Indenture a valid agreement of the Company, in accordance with their and its
terms.

reasonable care should know, that the certificate or opinion or representations

representations by, an officer or officers of the Company stating that the

Company, unless such counsel knows, or in the exercise of reasonable care should

matters are erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 104. Acts of Holders.

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section .

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner that the Trustee deems sufficient.

         (c) The principal amount and serial numbers of Securities held by any
Person, and the date of holding the same, shall be proved by the Security
Register.

         (d) If the Company shall solicit from the Holders of Securities any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at
<PAGE>   38
                                       27

its option, by or pursuant to a Board Resolution, fix in advance a record date
for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. Such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities shall be computed as of such record date;
provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than 120 days after the record
date.

         (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

         SECTION 105. Notices, Etc., to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1) the Trustee by any Holder or by the Company shall be sufficient for
     every purpose hereunder if made, given, furnished or filed in writing to or
     with the Trustee at its Corporate Trust Office, Attention: Corporate Trust
     Administration, or

         (2) the Company by the Trustee or by any Holder shall be sufficient for
     every purpose hereunder (unless otherwise herein expressly provided) if in
     writing and mailed, first-class postage prepaid, to the Company addressed
     to it at the address of its principal office specified in the heading of
     this Indenture, or at any other address previously furnished in writing to
     the Trustee by the Company.

         SECTION 106. Notice to Holders; Waiver.

         Where this Indenture provides for notice of any event to Holders by the
Company or the Trustee, such notice shall be sufficiently given (unless
otherwise herein
<PAGE>   39
                                       28

expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the Security
Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         In case by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impracticable to mail
notice of any event to Holders when such notice is required to be given pursuant
to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving
of such notice for every purpose hereunder.

         SECTION 107. Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         SECTION 108. Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         SECTION 109. Separability Clause.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

         SECTION 110. Benefits of Indenture.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto, any Paying Agent, any
Securities Registrar and their successors hereunder and the Holders, any benefit
or any legal or equitable right, remedy or claim under this Indenture.

         SECTION 111. Governing Law.

         This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York. Upon the issuance of the
Exchange Securities or the effectiveness of the Shelf Registration Statement,
this Indenture shall be subject to the provisions of the Trust Indenture Act
that are required to be part of this Indenture and shall, to the extent
applicable, be governed by such provisions; and, if and to the extent that any
provision of this Indenture limits, qualifies or conflicts with another
provision included in this Indenture which is required to be included in this
Indenture by any of Sections 310 to 318, inclusive, of the Trust Indenture Act,
such required provision shall control.

         SECTION 112. Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date, or Stated
Maturity or Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of principal (or premium, if any) or interest need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date, Redemption Date, or at the
Stated Maturity or Maturity; provided that no interest shall accrue for the
period from and after such Interest Payment Date, Redemption Date, Stated
Maturity or Maturity, as the case may be.

         SECTION 113. Agent for Service; Submission to Jurisdiction; Waiver of
Immunities.

         By the execution and delivery of this Agreement, the Company (i)
acknowledges that it has, by separate written instrument, designated and

this Indenture, the Securities, the Purchase Agreement, the Registration Rights
Agreement and the Warrant Agreement and, if issued, the Exchange Securities and

accepted such designation, (ii) submits to the jurisdiction of any such court in
any such suit or proceeding and (iii) agrees that service of process upon the
Process Agent and written notice of said service to the Company in accordance
with Section 105 of this Indenture shall be deemed in every respect effective
service of process upon the Company in any such suit or proceeding. The Company
further agrees to take any and all action, including the execution and filing of
any and all such documents and instruments, as may be necessary to continue such
designation and appointment of the Process Agent in full force and effect so
long as any of the Securities or Exchange Securities shall be outstanding;
provided that the Company may (and, to the extent the Process Agent ceases to be
able to be served on the basis
<PAGE>   41
                                       30

contemplated herein, shall), by written notice to the Trustee in accordance with
Section 105 of this Indenture, designate such additional or alternative agent
for service of process under this Section 113 that (i) maintains an office
located in The City of New York, Borough of Manhattan, State of New York, and

for other persons in the ordinary course of its business. Such written notice
shall identify the name of such agent for service of process and the address of
the office of such agent for service of process in The City of New York, Borough
of Manhattan, State of New York. Notwithstanding the foregoing, any suit, action
or proceeding based upon this Agreement may be instituted by the Trustee or any
Holder of any Security in any competent court in the Republic of Colombia.

         To the extent that the Company has or hereafter may acquire any
sovereign immunity from jurisdiction of any court or from any legal process
(whether through service of notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, it hereby irrevocably waives such sovereign immunity in respect of its
obligations under the above-referenced documents.

         SECTION 114. Judgment Currency.

Securities against any loss incurred by any of them as a result of any judgment

judgment or order being expressed and paid in a currency (the "Judgment
Currency") other than United States dollars and as a result of any variation as
between (i) the rate of exchange at which the United States dollar amount is
converted into the Judgment Currency for the purpose of such judgment or order
and (ii) the spot rate of exchange in The City of New York at which any such
person on the date of payment of such judgment or order is able to purchase
United States dollars with the amount of the Judgment Currency actually received
by such person. The foregoing indemnity shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "spot rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of, or conversion into, United States dollars.

                                 THE SECURITIES

         SECTION 301. Title and Terms.

         The aggregate principal amount at final maturity of Securities which
may be authenticated and delivered under this Indenture is limited to
$190,745,000, except for Securities authenticated and delivered upon
registration of transfer of, or in exchange for, or in lieu of, other Securities
pursuant to Section 304, 305, 308, 906, 1015, 1016 or 1108.

         The Initial Securities shall be known and designated as the "14% Senior
Discount Notes due 2004" and the Exchange Securities shall be known as the "14%
Series B Senior Discount Notes due 2004," in each case of the Company. Their
Stated Maturity shall be March 15, 2004 and, except as may be otherwise provided
for in the Securities, they shall bear interest at the rate of 14% per annum
from March 15, 2001, or from the most recent
<PAGE>   46
                                       35

Interest Payment Date to which interest has been paid or duly provided for,
payable on September 15, 2001 and semiannually thereafter on March 15 and
September 15 in each year and at said Stated Maturity, until the principal
thereof is paid or duly provided for.

         The principal of (and premium, if any) and interest on the Securities
shall be payable at the office or agency of the Company maintained for such
purpose in The City of New York, or at such other office or agency of the
Company as may be maintained for such purpose; provided, however, that, at the
option of the Company, interest may be paid by check mailed to addresses of the
Persons entitled thereto as such addresses shall appear on the Security
Register.

         The Securities shall be redeemable as provided in Article Eleven.

         The Securities shall be subject to the provisions of Article Fourteen
relating to the payment of proceeds of the Concession to the Banks in certain
circumstances.

         SECTION 302. Denominations.

         The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 and any integral multiple thereof.

         SECTION 303. Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of the Company by its
Chairman, its President or a Vice President, under its corporate seal reproduced
thereon. The signature of any of these officers on the Securities may be manual
or facsimile signatures of the present or any future such authorized officer and
may be imprinted or otherwise reproduced on the Securities. The seal of the
Company, if any, may be in the form of a facsimile thereof and may be impressed,
affixed, imprinted or otherwise reproduced on the Securities.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities. In addition, any Security may
be signed on behalf of the Company by such Persons as, at the actual date of the
execution of such Security, shall be the proper officers of the Company,
although at the date of such Security or of the execution of this Indenture any
such Person was not such officer.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities.
<PAGE>   47
                                       36

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein duly
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture.

         In case the Company, pursuant to Article Eight, shall be consolidated
or merged with or into any other Person or shall convey, transfer, lease or
otherwise dispose of its properties and assets substantially as an entirety to
any Person, and the successor Person resulting from such consolidation, or
surviving such merger, or into which the Company shall have been merged, or the
Person which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article Eight, any of the Securities authenticated
or delivered prior to such consolidation, merger, conveyance, transfer, lease or
other disposition may, from time to time, at the request of the successor
Person, be exchanged for other Securities executed in the name of the successor
Person with such changes in phraseology and form as may be appropriate, but
otherwise in substance of like tenor as the Securities surrendered for such
exchange and of like principal amount at maturity; and the Trustee, upon Company
Request of the successor Person, shall authenticate and deliver Securities as
specified in such Request for the purpose of such exchange. If Securities shall
at any time be authenticated and delivered in the name of a successor Person
pursuant to this Section in exchange or substitution for or upon registration of
transfer of any Securities, such successor Person, at the option of the Holders
but without expense to them, shall provide for the exchange of all Securities at
the time Outstanding for Securities authenticated and delivered in such name.

         SECTION 304. Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as conclusively evidenced
by their execution of such Securities.

         If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at the office
or agency of the Company designated for such purpose pursuant to Section 1002,
without charge to the Holder (except as provided in Section 305). Upon surrender
for cancellation of any one or more temporary Securities, the
<PAGE>   48
                                       37

Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount at maturity of definitive Securities of
authorized denominations. Until so exchanged, the temporary Securities shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities.

         SECTION 305. Registration, Registration of Transfer and Exchange.

         The Company shall keep or cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency designated pursuant to Section 1002 being herein
sometimes referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers and exchanges of Securities. The
Security Register shall be in written form or any other form capable of being
converted into written form within a reasonable time. At all reasonable times,
the Security Register shall be open to inspection by the Trustee. The Trustee is
hereby initially appointed as security registrar (the "Security Registrar") for
the purpose of registering Securities and transfers and exchanges of Securities
as herein provided.

         Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated pursuant to Section 1002, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of any
authorized denomination or denominations of a like aggregate principal amount at
maturity.

         At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denomination and of a like aggregate principal
amount at maturity, upon surrender of the Securities to be exchanged at such
office or agency. Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive; provided
that no exchange of Initial Securities for Exchange Securities shall occur until
an Exchange Offer Registration Statement shall have been declared effective by
the Commission and that the Initial Securities to be exchanged for the Exchange
Securities shall be cancelled by the Trustee.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company) be duly endorsed, or be
accompanied by a written instrument of transfer, in form satisfactory to the
Company and the Security Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing.
<PAGE>   49
                                       38

         No service charge shall be made for any registration of transfer or
exchange or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906, 1015, 1016 or 1108 not involving
any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange any Security during a period beginning at the opening of business
15 days before the selection of Securities to be redeemed under Section 1104 and
ending at the close of business on the day of mailing of the relevant notice of
redemption, or (ii) to register the transfer of or exchange any Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

         SECTION 306. Book-Entry Provisions for Global Securities. (a) The U.S.
Global Security and Offshore Global Security initially shall (i) be registered
in the name of the Depositary for such Global Securities or the nominee of such
Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Section 202.

         Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depositary, or the Trustee as its custodian, or under any
Global Security, and the Depositary may be treated by the Company, the Trustee
and any agent of the Company or the Trustee as the absolute owner of such Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a beneficial owner of any Security.

         (b) Transfers of a Global Security shall be limited to transfers of
such Global Security in whole, but not in part, to the Depositary, its
successors or their respective nominees. Interests of beneficial owners in a
Global Security may be transferred in accordance with the applicable rules and
procedures of the Depositary and the provisions of Section 307. In addition,
U.S. Physical Securities or Offshore Physical Securities shall be transferred to
all beneficial owners in exchange for their beneficial interests in the U.S.
Global Security or the Offshore Global Security, respectively, if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for the U.S. Global Security or the Offshore Global Security, as the
case may be, or the Depositary ceases to be a "Clearing Agency" registered under
the Exchange Act and a successor depositary is not appointed by the Company
within 90 days or (ii) an Event of Default has occurred and Holders of more than
25% in aggregate principal amount of the Securities at the time outstanding
represented by the Global Securities advise the Trustee through the Depositary
in
<PAGE>   50
                                       39

writing that the continuation of a book-entry system through the Depositary with
respect to the Global Securities is no longer required.

         (c) Any beneficial interest in one of the Global Securities that is
transferred to a person who takes delivery in the form of an interest in the
other Global Security will, upon transfer, cease to be an interest in such
Global Security and become an interest in the other Global Security and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Security for as long as it remains such an interest.

         (d) In connection with any transfer pursuant to paragraph (b) of this
Section of a portion of the beneficial interests in the U.S. Global Security to
beneficial owners who are required to hold U.S. Physical Securities, the
Registrar shall reflect on its books and records the date and a decrease in the
principal amount at maturity of the U.S. Global Security in an amount equal to
the principal amount at maturity of the beneficial interest in the U.S. Global
Security to be transferred, and the Company shall execute, and the Trustee shall
authenticate and deliver, one or more U.S. Physical Securities of like tenor and
amount.

         (e) In connection with the transfer of the entire U.S. Global Security
or Offshore Global Security to beneficial owners pursuant to paragraph (b) of
this Section , the U.S. Global Security or Offshore Global Security, as the case
may be, shall be deemed to be surrendered to the Trustee for cancellation, and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the U.S. Global Security or Offshore Global Security, as
the case may be, an equal aggregate principal amount at maturity of U.S.
Physical Securities or Offshore Physical Securities, as the case may be, of
authorized denominations.

         (f) Any U.S. Physical Security delivered in exchange for an interest in
the U.S. Global Security pursuant to paragraph (b) or (d) of this Section shall,
except as otherwise provided by paragraph (a)(i)(x) or paragraph (e) of Section 
307, bear the legend regarding transfer restrictions applicable to the U.S.
Physical Security set forth in Section 202.

         (g) The registered holder of a Global Security may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

         (h) Beneficial owners of interests in a Global Security may receive
Physical Securities (which shall bear the Private Placement Legend if required
by Section 202) in accordance with the procedures of the Depositary. In
connection with the execution, authentication and delivery of such Physical
Securities, the Registrar shall reflect on its books and records a decrease in
the principal amount at maturity of the relevant Global Security
<PAGE>   51
                                       40

equal to the principal amount at maturity of such Physical Securities and the
Company shall execute and the Trustee shall authenticate and deliver one or more
Physical Securities having an equal aggregate principal amount at maturity.

         SECTION 307. Special Transfer Provisions. Unless and until (i) an
Initial Security is sold under an effective Registration Statement, or (ii) an
Initial Security is exchanged for an Exchange Security in connection with an
effective Registration Statement, in each case pursuant to the Registration
Rights Agreement, the following provisions shall apply:

         (a) Transfers to Non-QIB Institutional Accredited Investors. The
     following provisions shall apply with respect to the registration of any
     proposed transfer of an Initial Security to any Institutional Accredited

                  (i) The Registrar shall register the transfer of any Security,
          whether or not such Security bears the Private Placement Legend, if
          (x) the requested transfer is at least three years after the original
          issue date of the Initial Securities or (y) the proposed transferee
          has delivered to the Registrar a certificate substantially in the form
          of Exhibit C hereto.

                  (ii) If the proposed transferor is an Agent Member holding a
          beneficial interest in the U.S. Global Security, upon receipt by the
          Registrar of (x) the documents, if any, required by paragraph (i), and
          (y) instructions given in accordance with the Depositary's and the
          Registrar's procedures therefor, the Registrar shall reflect on its
          books and records the date and a decrease in the principal amount of
          the U.S. Global Security in an amount equal to the principal amount of
          the beneficial interest in the U.S. Global Security to be transferred,
          and the Company shall execute, and the Trustee shall authenticate and
          deliver, one or more U.S. Physical Securities of like tenor and
          amount.

         (b) Transfers to QIBs. The following provisions shall apply with
     respect to the registration of any proposed transfer of a U.S. Physical
     Security or an interest in the U.S. Global Security to a QIB (excluding
     Non-U.S. Persons):

                  (i) If the Security to be transferred consists of (x) U.S.
          Physical Securities, the Security Registrar shall register the
          transfer if such transfer is being made by a proposed transferor who
          has checked the box provided for on the form of Initial Security
          stating, or has otherwise advised the Company and the Security
          Registrar in writing, that the sale has been made in compliance with
          the provisions of Rule 144A to a transferee who has signed the
          certification provided for on the form of Initial Security stating, or
          has otherwise advised the Company and the Security Registrar in
          writing, that it is purchasing the Initial Security for its own
          account or an account with respect
<PAGE>   52
                                       41

          to which it exercises sole investment discretion and that it and any
          such account is a QIB within the meaning of Rule 144A, and is aware
          that the sale to it is being made in reliance on Rule 144A and
          acknowledges that it has received such information regarding the
          Company as it has requested pursuant to Rule 144A or has determined
          not to request such information and that it is aware that the
          transferor is relying upon its foregoing representations in order to
          claim the exemption from registration provided by Rule 144A or (y) an
          interest in the U.S. Global Security, the transfer of such interest
          may be effected only through the book-entry system maintained by the
          Depositary.

                  (ii) If the proposed transferee is an Agent Member, and the
          Security to be transferred consists of U.S. Physical Securities, upon
          receipt by the Security Registrar of the documents referred to in
          clause (i) and instructions given in accordance with the Depositary's
          and the Security Registrar's procedures, the Security Registrar shall
          reflect on its books and records the date and an increase in the
          principal amount at maturity of the U.S. Global Security in an amount
          equal to the principal amount at maturity of the U.S. Physical
          Securities to be transferred, and the Trustee shall cancel the
          Physical Securities so transferred.

         (c) Transfers of Interests in the Offshore Global Security or Offshore
     Physical Securities to U.S. Persons. The following provisions shall apply

          the Offshore Global Security or Offshore Physical Securities pursuant
          to Section 202, the Security Registrar shall refuse to register such
          transfer; and

                  (ii) after such removal, the Security Registrar shall register
          the transfer of any such Security without requiring any additional
          certification.

         (d) Transfers to Non-U.S. Persons at Any Time. The following provisions
     shall apply with respect to any transfer of an Initial Security to a
     Non-U.S. Person:

                  (i) The Security Registrar shall register any proposed
          transfer to any Non-U.S. Person if the Security to be transferred is a
          U.S. Physical Security or an interest in the U.S. Global Security only
          upon receipt of a certificate substantially in the form of Exhibit D
          from the proposed transferor.

                  (ii) (x) If the proposed transferee is an Agent Member holding
          a beneficial interest in the U.S. Global Security, upon receipt by the
          Security Registrar of (1) the documents required by paragraph (i) and
          (2) instructions in accordance with the Depositary's and the Security
          Registrar's procedures, the
<PAGE>   53
                                       42

         Security Registrar shall reflect on its books and records the date and
         a decrease in the principal amount at maturity of the U.S. Global
         Security in an amount equal to the principal amount at maturity of the
         beneficial interest in the U.S. Global Security to be transferred, and
         (y) if the proposed transferee is an Agent Member, upon receipt by the
         Security Registrar of instructions given in accordance with the
         Depositary's and the Security Registrar's procedures, the Security
         Registrar shall reflect on its books and records the date and an
         increase in the principal amount at maturity of the Offshore Global
         Security in an amount equal to the principal amount at maturity of the
         U.S. Physical Security or the U.S. Global Security, as the case may be,
         to be transferred, and the Trustee shall cancel the Physical Security,
         if any, so transferred or decrease the amount of the U.S. Global
         Security.

         (e) Private Placement Legend. Upon the transfer, exchange or
     replacement of Securities not bearing the Private Placement Legend, the
     Security Registrar shall deliver Securities that do not bear the Private
     Placement Legend. Upon the transfer, exchange or replacement of Securities
     bearing the Private Placement Legend, the Security Registrar shall deliver
     only Securities that bear the Private Placement Legend unless either (i)
     the Private Placement Legend is no longer required by Section 202 or (ii)
     there is delivered to the Security Registrar an Opinion of Counsel
     reasonably satisfactory to the Company and the Trustee to the effect that
     neither such legend nor the related restrictions on transfer are required
     in order to maintain compliance with the provisions of the Securities Act.

         (f) General. By its acceptance of any Security bearing the Private
     Placement Legend, each Holder of, or beneficial owner of an interest in,
     such Security acknowledges the restrictions on transfer of such Security
     set forth in this Indenture and in the Private Placement Legend and agrees
     that it will transfer such Security only as provided in this Indenture. The
     Security Registrar shall not register a transfer of any Security unless
     such transfer complies with the restrictions on transfer of such Security
     set forth in this Indenture. In connection with any transfer of Securities
     to an Institutional Accredited Investor, each such Holder or beneficial
     owner agrees by its acceptance of the Securities to furnish the Security
     Registrar or the Company such certifications, legal opinions or other
     information as such Person may reasonably require to confirm that such
     transfer is being made pursuant to an exemption from, or a transaction not
     subject to, the registration requirements of the Securities Act; provided
     that the Security Registrar shall not be required to determine (but may
     rely on a determination made by the Company with respect to) the
     sufficiency of any such certifications, legal opinions or other
     information.

         Every replacement Security is an additional obligation of the Company
and shall be entitled to the benefits of this Indenture.

         SECTION 308. Mutilated, Destroyed, Lost and Stolen Securities.

         If (i) any mutilated Security is surrendered to the Trustee, or (ii)
the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company and the Trustee such security or indemnity as may be required by them to
save each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
deliver, in exchange for any such mutilated Security or in lieu of any such
destroyed, lost or stolen Security, a new Security of like tenor, form, terms
and principal amount, bearing a number not contemporaneously Outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay or authorize the payment of such
Security.

         Upon the issuance of any new Security under this Section , the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

         All Securities shall be held and owned upon the express condition that
the foregoing provisions of this Section are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities, and
shall preclude any and all other rights or remedies, notwithstanding any law or
statute existing or hereinafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

         SECTION 309. Payment of Interest; Interest Rights Preserved.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name such Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest at the
office or agency of the Company maintained for such purpose pursuant to Section 
1002; provided, however, that each installment of interest may at the Company's
option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 310, to the
address of such Person as it appears in the Security Register at the close of
business on the Regular
<PAGE>   55
                                       44

Record Date for such interest payment or (ii) transfer to an account located in
the United States maintained by the payee the details of which account are
notified to the Security Registrar prior to the close of business on the Record
Date for such interest payment.

         Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date shall forthwith cease to
be payable to the Holder on the Regular Record Date by virtue of having been
such Holder, and such defaulted interest and (to the extent lawful) interest on
such defaulted interest at the rate borne by the Securities (such defaulted
interest and interest thereon herein collectively called "Defaulted Interest")
may be paid by the Company, at its election in each case, as provided in clause
(1) or (2) below:

         (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities (or their respective Predecessor
     Securities) are registered at the close of business on a Special Record
     Date for the payment of such Defaulted Interest, which shall be fixed in
     the following manner. The Company shall notify the Trustee in writing of
     the amount of Defaulted Interest proposed to be paid on each Security and
     the date of the proposed payment, and at the same time the Company shall
     deposit with the Trustee an amount of money equal to the aggregate amount
     proposed to be paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory to the Trustee for such deposit prior to the date
     of the proposed payment, such money when deposited to be held in trust for
     the benefit of the Persons entitled to such Defaulted Interest as in this
     clause provided. Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days after the receipt by the Trustee of the notice of the
     proposed payment. The Trustee shall promptly notify the Company of such
     Special Record Date, and in the name and at the expense of the Company,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be given in the manner provided for in
     Section 106, not less than 10 days prior to such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been so given, such Defaulted Interest shall be
     paid to the Persons in whose names the Securities (or their respective
     Predecessor Securities) are registered at the close of business on such
     Special Record Date and shall no longer be payable pursuant to the
     following clause (2).

         (2) The Company may make payment of any Defaulted Interest in any other
     lawful manner not inconsistent with the requirements of any securities
     exchange on which the Securities may be listed, and upon such notice as may
     be required by such exchange, if, after notice given by the Company to the
     Trustee of the proposed payment pursuant to this clause, such manner of
     payment shall be deemed practicable by the Trustee.
<PAGE>   56
                                       45

         Subject to the foregoing provisions of this Section , each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

         SECTION 310. Persons Deemed Owners.

         Prior to the due presentment of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered as the owner of
such Security for the purpose of receiving payment of principal of (and premium,
if any) and (subject to Sections 305 and 309) interest on such Security and for
all other purposes whatsoever, whether or not such Security be overdue, and none
of the Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         SECTION 311. Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and may deliver to the Trustee (or to any
other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. If
the Company shall so acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for cancellation. No Securities shall be authenticated in lieu of or in
exchange for any Securities cancelled as provided in this Section , except as
expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with its customary
procedures and certification of their disposal delivered to the Company unless
by Company Order the Company shall direct that cancelled Securities be returned
to it.

         SECTION 312. Computation of Interest.

         Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

         SECTION 313. Wire Transfers.

         Notwithstanding any other provision to the contrary in this Indenture,
the Company may make any payment of monies required to be deposited with the
Trustee on account of principal of, or premium, if any, or interest on, the
Securities (whether pursuant
<PAGE>   57
                                       46

to optional or mandatory redemption payments, interest payments or otherwise) by
wire transfer in immediately available funds to an account designated by the
Trustee on or before 10:00 a.m. (New York City time) the date such moneys are to
be paid to the Holders of the Securities in accordance with the terms hereof.

                           SATISFACTION AND DISCHARGE

         SECTION 401. Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Request cease to be of further effect
(except as to surviving rights and obligations of the Trustee expressly provided
for in this Indenture and the surviving rights of registration of transfer or
exchange of Securities expressly provided for herein or pursuant hereto) and the
Trustee, at the direction and expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture when

         (1) either

                  (a) all Securities theretofore authenticated and delivered
         (other than (i) Securities which have been destroyed, lost or stolen
         and which have been replaced or paid as provided in Section 308 and
         (ii) Securities for whose payment money has theretofore been deposited
         in trust with the Trustee or any Paying Agent or segregated and held in
         trust by the Company and thereafter repaid to the Company or discharged
         from such trust, as provided in Section 1003) have been delivered to
         the Trustee for cancellation; or

                  (b) all such Securities not theretofore delivered to the
         Trustee for cancellation

                           (i) have become due and payable, or

                           (ii) will become due and payable at their Stated
                  Maturity within one year, or

                           (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company,

         and the Company, in the case of (i), (ii) or (iii) above, has
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust for
<PAGE>   58
                                       47

         such purpose an amount sufficient to pay and discharge the entire
         indebtedness on such Securities not theretofore delivered to the
         Trustee for cancellation, for principal of (and premium, if any) and
         interest to the date of such deposit (in the case of Securities which
         have become due and payable) or to the Stated Maturity or Redemption
         Date, as the case may be;

         (2) the Company has paid or caused to be paid all other sums payable
     hereunder by the Company; and

         (3) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section , the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

         SECTION 402. Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee; but such money need not be segregated from other funds except to the
extent required by law. So long as no Event of Default shall have occurred and
be continuing, all interest allowed on any such moneys shall be paid from time
to time to the Company upon a Company Order.

         SECTION 502. Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than an Event of Default specified in
Section 501(8) or (9)) occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Securities Outstanding may declare the principal of all the Securities to be due
and payable immediately in an amount equal to (i) the Accreted Value of the
Securities as of the date on which the Securities first become due and payable,
if such date occurs prior to March 15, 2001, or (ii) the Accreted Value of the
Securities as of the date on which the Securities first become due and payable
plus accrued and unpaid interest, if any, to such date, if such date occurs on
or after March 15, 2001, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal shall
become immediately due and payable. If an Event of Default specified in Section 
501(8) or (9) occurs and is continuing,
<PAGE>   61
                                       50

then the principal of all the Securities shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder in an amount equal to (i) the Accreted Value of the
Securities as of the date on which the Securities first become due and payable,
if such date occurs prior to March 15, 2001, or (ii) the Accreted Value of the
Securities as of the date on which the Securities first become due and payable
plus accrued and unpaid interest, if any, to such date, if such date occurs on
or after March 15, 2001.

         At any time after a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter provided in this Article, the Holders of a majority
in principal amount of the Securities Outstanding, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if

         (1) the Company has paid or deposited with the Trustee a sum sufficient
     to pay,

                  (A) all overdue interest on all Outstanding Securities,

                  (B) all unpaid principal of and premium, if any, on any
          Outstanding Securities which has become due otherwise than by such
          declaration of acceleration, and interest on such unpaid principal at
          the rate borne by the Securities,

                  (C) to the extent that payment of such interest is lawful,
          interest on overdue interest and overdue principal at the rate borne
          by the Securities, and

                  (D) all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel; and

         (2) all Events of Default, other than the non-payment of amounts of
     principal of or premium, if any, on or interest on Securities which have
     become due solely by such declaration of acceleration, have been cured or
     waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

         SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee.

         The Company covenants that if
<PAGE>   62
                                       51

         (a) default is made in the payment of any installment of interest on
     any Security when such interest becomes due and payable and such default
     continues for a period of 30 days, or

         (b) default is made in the payment of the principal of or premium, if
     any, on any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee for the benefit
of the Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and interest on any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installment of interest,
at the rate borne by the Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

         SECTION 504. Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

         (i) to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     and to file
<PAGE>   63
                                       52

     such other papers or documents as may be necessary or advisable in order to
     have the claims of the Trustee (including any claim for the reasonable
     compensation, expenses, disbursements and advances of the Trustee, its
     agents and counsel) and of the Holders allowed in such judicial proceeding,
     and

         (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

         SECTION 505. Trustee May Enforce Claims Without Possession of
Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
and as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         SECTION 506. Application of Money Collected.

         Subject to Article Fourteen, any money collected by the Trustee
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on

Securities and the notation thereon of the payment, if only partially paid, and
upon surrender thereof if fully paid:

         FIRST: To the payment of all amounts due the Trustee under Section 606;
<PAGE>   64
                                       53

         SECOND: To the payment of the amounts then due and unpaid for principal

         SECTION 507. Limitation on Suits.

         No Holder of any Securities shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

         (1) such Holder has previously given written notice to the Trustee of a
     continuing Event of Default;

         (2) the Holders of not less than 25% in principal amount of the
     Outstanding Securities shall have made written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

         (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

         (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such action or
     proceeding; and

         (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority or
     more in principal amount of the Outstanding Securities;

it being understood and intended, and being expressly covenanted by the Holder
of every Security with every other Holder and the Trustee, that no one or more
Holders shall have any right in any manner whatever by virtue of, or by availing
of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other Holders, or to obtain or to seek to obtain priority or preference
over any other Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all the
Holders.

         SECTION 508. Unconditional Right of Holders to Receive Principal,
Premium and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment, as provided herein (including, if applicable, Article Thirteen)
and in such Security of the principal of (and premium, if any) and (subject to
Section 309) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment on or after
such respective dates, and such rights shall not be impaired without the consent
of such Holder.

         SECTION 509. Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

         SECTION 510. Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 308, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

         SECTION 511. Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

         SECTION 512. Control by Holders.
<PAGE>   66
                                       55

         Subject to the provisions of Section 602(5), the Holders of not less
than a majority in principal amount of the Outstanding Securities shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, provided that

         (1) such direction shall not be in conflict with any rule of law or
     with this Indenture,

         (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction, and

         (3) the Trustee need not take any action which might involve it in
     personal liability or be unjustly prejudicial to the Holders not
     consenting.

         SECTION 513. Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities may, on behalf of the Holders of all the Securities,
waive any past Default hereunder and its consequences, except a Default

         (1) in respect of the payment of the principal of (or premium, if any)
     or interest on any Security, or

         (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security affected.

         Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

         SECTION 514. Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

         SECTION 601. Notice of Defaults.

         Within 30 days after the occurrence of any Default hereunder, the
Trustee shall transmit in the manner and to the extent provided in TIA Section 
313(c), notice of such Default hereunder known to the Trustee, unless such
Default shall have been cured or waived; provided, however, that, except in the
case of a Default in the payment of the principal of (or premium, if any) or
interest on any Security, the Trustee shall be protected in withholding such
notice if and so long as a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders; and provided further that in the case
of any Default of the character specified in Section 501(4) no such notice to
Holders shall be given until at least 30 days after the occurrence thereof.

         SECTION 602. Certain Rights of Trustee.

         Subject to the provisions of TIA Sections 315(a) through 315(d):

         (1) the Trustee may rely and shall be protected in acting or refraining
     from acting upon any resolution, certificate, statement, instrument,
     opinion, report, notice, request, direction, consent, order, bond,
     debenture, note, other evidence of indebtedness or other paper or document
     believed by it to be genuine and to have been signed or presented by the
     proper party or parties;

         (2) any request or direction of the Company mentioned herein shall be
     sufficiently evidenced by a Company Request or Company Order (unless other
     evidence in respect thereof is herein specifically prescribed) and any
     resolution of the Board of Directors may be sufficiently evidenced by a
     Board Resolution;

         (3) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence is herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

         (4) the Trustee may consult with counsel and the written advice of such
     counsel or any Opinion of Counsel shall be full and complete authorization
     and protection in respect of any action taken, suffered or omitted by it
     hereunder in good faith and in reliance thereon;
<PAGE>   68
                                       57

         (5) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

         (6) prior to the occurrence of an Event of Default and after the curing
     of all Events of Default which may have occurred, the Trustee shall not be
     bound to make any investigation into the facts or matters stated in any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, direction, consent, order, bond, debenture, note, other evidence
     of indebtedness or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney;

         (7) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder; and

         (8) the Trustee shall not be liable for any action taken, suffered or
     omitted by it in good faith and believed by it to be authorized or within
     the discretion or rights or powers conferred upon it by this Indenture.

         The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

         SECTION 603. Trustee Not Responsible for Recitals or Issuance of
Securities.

         The recitals contained herein and in the Securities, except for the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.

Indenture or of the Securities, except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture, authenticate the
Securities and perform its obligations hereunder and that the statements made by
it in any Statement of Eligibility on Form T-1 supplied to the Company will be
true and accurate, subject to the qualifications set forth therein. The Trustee
shall not be accountable for the use or application by the Company of Securities
or the proceeds thereof.
<PAGE>   69
                                       58

         SECTION 604. May Hold Securities.

         The Trustee, any Paying Agent, any Security Registrar or any other
agent of the Company or of the Trustee, in its individual or any other capacity,
may become the owner or pledgee of Securities and, subject to the Trust
Indenture Act, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Paying Agent, Security Registrar or such other
agent.

         SECTION 605. Money Held in Trust.

         Subject to the provisions of Section 506, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company. So long as no Event of Default shall have occurred and
be continuing, all interest allowed on any such moneys shall be paid from time
to time to the Company upon a Company Order.

         SECTION 606. Compensation and Reimbursement.

         The Company agrees:

         (1) to pay to the Trustee from time to time such compensation as the
     Company and the Trustee shall agree in writing for all services rendered by
     it hereunder (which compensation shall not be limited by any provision of
     law in regard to the compensation of a trustee of an express trust);

         (2) to reimburse the Trustee upon its request for all reasonable
     expenses, disbursements and advances incurred or made by the Trustee in
     accordance with any provision of this Indenture (including the reasonable
     compensation and the expenses and disbursements of its agents and counsel),
     except any such expense, disbursement or advance as may be attributable to
     its negligence or bad faith; and

         (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of this trust, including the costs and expenses of investigating or
     defending itself against any claim or liability in connection with the
     exercise or performance of any of its powers or duties hereunder.

         The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the resignation or removal
of the Trustee and/or the satisfaction and discharge of this Indenture. As
security for the performance of such obligations of the Company, the Trustee
<PAGE>   70
                                       59

shall have a claim prior to the Securities upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the payment of
principal of (and premium, if any) or interest on particular Securities.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(8) or (9), the expenses (including
the reasonable charges and expenses of its counsel) of and the compensation for
such services are intended to constitute expenses of administration under any
applicable federal or state bankruptcy, insolvency or other similar Colombian or
other foreign law.

         The provisions of this Section shall survive the termination of this
Indenture.

         SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests.

         There shall be at all times a Trustee hereunder which shall be eligible
to act as Trustee under TIA Section 310(a)(1) and 310(a)(5) and shall have a
combined capital and surplus of at least $50,000,000. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section , the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section , it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.

         SECTION 608. Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

         (b) The Trustee may resign at any time by giving written notice thereof
to the Company. If the instrument of acceptance by a successor Trustee required
by Section 609 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

         (c) The Trustee may be removed at any time by Act of the Holders of not
less than a majority in principal amount of the Outstanding Securities,
delivered to the Trustee and to the Company.

         (d) If at any time:
<PAGE>   71
                                       60

         (1) the Trustee shall fail to comply with the provisions of TIA 
     Section 310(b) after written request therefor by the Company or by any 
     Holder who has been a bona fide Holder of a Security for at least six 
     months, or

         (2) the Trustee shall cease to be eligible under Section 607 and shall
     fail to resign after written request therefor by the Company or by any
     Holder who has been a bona fide Holder of a Security for at least six
     months, or

         (3) the Trustee shall become incapable of acting or shall be adjudged a
     bankrupt or insolvent or a receiver of the Trustee or of its property shall
     be appointed or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation,

then, in any such case, (i) the Company, by a Board Resolution, may remove the 
Trustee, or (ii) subject to TIA Section 315(e), any Holder who has been a bona 
fide Holder of a Security for at least six months may, on behalf of himself 
and all others similarly situated, petition any court of competent 
jurisdiction for the removal of the Trustee and the appointment of a successor 
Trustee.

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders and accepted appointment in the manner hereinafter provided, any Holder
who has been a bona fide Holder of a Security for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee.

         (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee to the Holders of
Securities in the manner provided for in Section 106. Each notice shall include
the name of the successor Trustee and the address of its Corporate Trust Office.

         SECTION 609. Acceptance of Appointment by Successor.

         Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested
<PAGE>   72
                                       61

with all the rights, powers, trusts and duties of the retiring Trustee; but, on
request of the Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder. Upon request of any
such successor Trustee, the Company shall execute any and all instruments for
more fully and certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts.

         No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified under the TIA and
eligible under this Article.

         SECTION 610. Merger, Conversion, Consolidation or Succession to
Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities. In
case at that time any of the Securities shall not have been authenticated, any
successor Trustee may authenticate such Securities either in the name of any
predecessor hereunder or in the name of the successor Trustee. In all such cases
such certificates shall have the full force and effect which this Indenture
provides for the certificate of authentication of the Trustee shall have;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or to authenticate Securities in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

agent of either of
<PAGE>   73
                                       62

them shall be held accountable by reason of the disclosure of any information as

regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under TIA Section 312(b).

         SECTION 702. Reports by Trustee.

         Within 60 days after May 15 of each year commencing with the first May

Holders, in the manner and to the extent provided in TIA Section 313(c), a brief
report dated as of such May 15 if required by TIA Section 313(a).

transactions, consolidate with or merge with or into any other Person or sell,
assign, convey, transfer, lease or otherwise dispose of all or substantially all
of its properties and assets substantially as an entirety to any other Person or
Persons or permit any of its Restricted Subsidiaries to enter into any such
transaction or series of transactions if such transaction or series of
transactions, in the aggregate, would result in the sale, assignment,
conveyance, transfer, lease or other disposition of all or substantially all of
the properties and assets of the Company and its Restricted Subsidiaries on a
consolidated basis as an entirety to any other Person or Persons, unless:

         (1) either (A) the Company shall be the continuing corporation or (B)
     the Person (if other than the Company) formed by such consolidation or into
     which the Company or such Restricted Subsidiary is merged or the Person
     which acquires by sale, assignment, conveyance, transfer, lease or
     disposition all or substantially all of the properties and assets of the
     Company and its Restricted Subsidiaries on a consolidated basis as an
     entirety (the "Surviving Entity") (i) shall be a corporation duly organized
     and validly existing under the laws of the Republic of Colombia and (ii)
     shall expressly assume, by a supplemental indenture in form satisfactory to
     the Trustee, the Company's obligation for the due and punctual payment of

     of the Company or any Restricted Subsidiary incurred in connection with or
     as a result of such transaction or series of transactions as having been
     incurred at the time of such transaction), no Default or Event of Default
     shall have occurred and be continuing;

         (3) immediately after giving effect to such transaction or series of
     transactions on a pro forma basis (and treating any obligation of the
     Company or any Restricted Subsidiary incurred in connection with or as a
     result of such transaction or series of transactions as having been
     incurred at the time of such transaction), the Consolidated Net Worth of
     the Company (or of the Surviving Entity if the Company is not the
     continuing obligor under this Indenture) is equal to or greater than the
     Consolidated Net Worth of the Company immediately prior to such transaction
     or series of transactions;

         (4) immediately after giving effect to such transaction or series of

     (other than Permitted Indebtedness) under the provisions of Section 1010.

         (5) the Company or the Surviving Entity shall have delivered to the
     Trustee, in form and substance reasonably satisfactory to the Trustee, an
     Officers' Certificate (attaching the authentic computations to demonstrate
     compliance with clauses (3) and (4) above) and an Opinion of Counsel, each
     stating that such consolidation, merger, sale, assignment, conveyance,
     transfer, lease or other disposition, and, if a supplemental indenture is
     required in connection with such transaction, such supplemental indenture,
     comply with the requirements of this Indenture and that all conditions
     precedent therein provided for relating to such transaction have been
     complied with.

         SECTION 802. Successor Substituted.

         Upon any consolidation or merger, or any sale, assignment, conveyance,
transfer, lease or disposition of all or substantially all of the properties and
assets of the Company in accordance with Section 801 in which the Company is not
the continuing obligor under this Indenture, the Surviving Entity shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor had been
named as the Company herein and, in the event of any such conveyance or
transfer, the Company (which term shall for this purpose mean the Person named
as the "Company" in the first paragraph of this Indenture or any successor
Person
<PAGE>   75
                                       64

which shall theretofore become such in the manner described in Section 801),
except in the case of a transfer by lease, shall be discharged of all
obligations and covenants under this Indenture and the Securities and may be
dissolved and liquidated.

         SECTION 803. Securities to Be Secured in Certain Events.

         If, upon any such consolidation of the Company with or merger of the
Company into any other corporation, or upon any sale, assignment, conveyance,
lease, transfer or disposition of all or substantially all of the properties and
assets of the Company substantially as an entirety to any other Person or
Persons, any property or assets of the Company would thereupon become subject to
any Lien, then unless such Lien could be created pursuant to Section 1014
without equally and ratably securing the Securities, the Company, prior to or
simultaneously with such consolidation, merger, conveyance, lease or transfer,
will as to such property or assets, secure the Securities Outstanding (together
with, if the Company shall so determine any other Indebtedness of the Company
now existing or hereinafter created which is not subordinate in right of payment
to the Securities) equally and ratably with (or prior to) the Indebtedness which
upon such consolidation, merger, conveyance, lease or transfer is to become
secured as to such property or assets by such Lien, or will cause such
Securities to be so secured.

     including any of which are required to be mortgaged, pledged or
     hypothecated, or in which a security interest is required to be granted to
     the Trustee pursuant to Section 803 or 1014 or otherwise.

         SECTION 902. Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in

consent of the Holder of each Outstanding Security affected thereby:

         (1) change the Stated Maturity of the principal of, or any installment
     of interest on, any Security, or reduce the principal amount thereof (or
     premium, if any) or the rate of interest thereon or reduce the amount of
     the principal of the Securities that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to Section 502

     Asset Sale in accordance with Section 1016 or the obligation of the Company
     to make and consummate a Change of Control Offer in the event of a Change

         (5) except as otherwise provided by Article Eight, consent to the
     assignment or transfer by the Company of any of its obligations under this
     Indenture.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

         SECTION 903. Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of Counsel stating that
the execution of such supplemental indenture is authorized or permitted by this
Indenture. The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which adversely affects the Trustee's own rights, duties
or immunities under this Indenture or otherwise.

         SECTION 904. Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,

                                       67

         SECTION 905. Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to the Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 906. Reference in Securities to Supplemental Indentures.

         Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities so modified as to conform, in the opinion of the Trustee and the
Company, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities. Failure to make the appropriate notation or to issue a
new Security shall not affect the validity of such amendment.

         SECTION 907. Notice of Supplemental Indentures.

         Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of Section 902, the Company
shall give notice thereof to the Holders of each Outstanding Security affected,
in the manner provided for in Section 106, setting forth in general terms the
substance of such supplemental indenture. Failure to provide such notice shall

                                    COVENANTS

         SECTION 1001. Payment of Principal, Premium, if any, and Interest.

         The Company covenants and agrees for the benefit of the Holders that it
will duly and punctually pay or cause to be paid the principal of (and premium,
if any) and interest on the Securities in accordance with the terms of the
Securities and this Indenture.
<PAGE>   79
                                       68

         SECTION 1002. Maintenance of Office or Agency.

         The Company will maintain in The City of New York, an office or agency
where Securities may be presented or surrendered for payment, where Securities
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Corporate Trust Office of the Trustee shall be such
office or agency of the Company, unless the Company shall designate and maintain
some other office or agency for one or more of such purposes. The Company will
give prompt written notice to the Trustee of any change in the location of any
such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies (in or outside of The City of New York) where the Securities
may be presented or surrendered for any or all such purposes and may from time
to time rescind any such designation; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in The City of New York for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and any change in the location of any such other
office or agency.

         SECTION 1003. Money for Security Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent, it will,
on or before each due date of the principal of (or premium, if any) or interest
on any of the Securities, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal of (or premium,
if any) or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for the
Securities, it will, on or before 10:00 a.m. on each due date of the principal
of (or premium, if any) or interest on any Securities, deposit with a Paying
Agent a sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of such action or
any failure so to act.

         The Company will cause each Paying Agent (other than the Trustee) to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section , that
such Paying Agent will:
<PAGE>   80
                                       69

         (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Securities in trust for the benefit of the
     Persons entitled thereto until such sums shall be paid to such Persons or
     otherwise disposed of as herein provided;

         (2) give the Trustee notice of any default by the Company (or any other
     obligor upon the Securities) in the making of any payment of principal (and
     premium, if any) or interest; and

         (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

         Notwithstanding anything in this Section 1003 to the contrary, the
Company may at any time, for the purpose of obtaining the satisfaction and
discharge of this Indenture or for any other purpose, pay, or by Company Order
direct any Paying Agent to pay, to the Trustee all sums held in trust by the
Company or such Paying Agent, such sums to be held by the Trustee upon the same
trusts as those upon which such sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such sums.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (or premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal, premium or interest has become due and payable shall be paid to
the Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, The City of New York, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

         SECTION 1004. Corporate Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect the corporate
existence, rights (charter and statutory) and franchises of the Company and each
Subsidiary; provided, however, that the Company shall not be required to
preserve any such right or franchise if the Board of
<PAGE>   81
                                       70

Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and its Subsidiaries as a whole
and that the loss thereof is not disadvantageous in any material respect to the
Holders.

         SECTION 1005. Payment of Taxes and Other Claims.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary and (b)
all lawful claims for labor, materials and supplies, which, if unpaid, might by
law become a material lien upon the property of the Company or any Subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings.

         SECTION 1006. Maintenance of Properties.

         The Company will cause all properties owned by the Company or any
Subsidiary or used or held for use in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from discontinuing the maintenance of any of such properties
if such discontinuance is, in the judgment of the Company, desirable in the
conduct of its business or the business of any Subsidiary and not
disadvantageous in any material respect to the Holders.

         SECTION 1007. Insurance.

         The Company will at all times keep all of its and its Subsidiaries
properties which are of an insurable nature insured with insurers, believed by
the Company to be responsible, against loss or damage to the extent that
property of similar character is usually so insured by corporations similarly
situated and owning like properties.

         SECTION 1008. Statement by Officers as to Default.

         (a) The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year, a brief certificate from the principal executive
officer, principal financial officer or principal accounting officer as to his
or her knowledge of the Company's compliance with all conditions and covenants
under this Indenture. For purposes of this
<PAGE>   82
                                       71

Section 1008(a), such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture.

         (b) When any Default has occurred and is continuing under this
Indenture, or if the trustee for or the holder of any other evidence of
Indebtedness of the Company or any Subsidiary gives any notice or takes any
other action with respect to a claimed default (other than with respect to
Indebtedness in the principal amount of less than $3,000,000), the Company shall
deliver to the Trustee by registered or certified mail or by telegram, telex or
facsimile transmission an Officers' Certificate specifying such event, notice or
other action within five Business Days of its occurrence.

         SECTION 1009. Provision of Reports and Financial Statements.

         (a) The Company shall file with the Trustee and provide the Holders of
Securities, within 15 days after it files them with the Commission, copies of
its annual and quarterly reports and other information, documents and other
reports (or copies of such portions of any of the foregoing as the Commission
may by rules and regulations prescribe) which the Company is required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act.

         (b) Notwithstanding that the Company may not be required to remain

Offer Registration Statement with the Commission and in the event that the
Company never becomes subject to the reporting requirements of Section 13(a) or
15(d) of the Exchange Act, the Company shall provide to the Trustee and to the

         Company, together with the aggregate Net Cash Proceeds and the Fair
         Market Value of property received by the Company at the time of such
         conversion or exchange, plus

                  (D) to the extent not otherwise included in the Consolidated
         Cash Flow of the Company, an amount equal to the sum of (i) the net
         reduction in Investments in any Person (other than the Permitted
         Investments) resulting from the payment in cash of dividends,
         repayments of loans or advances or other transfers of assets, in each
         case to the Company or any Restricted Subsidiary after the Issue Date
         from such Person, and (ii) the portion (proportionate to the Company's
         equity interest in such Subsidiary) of the fair market value of the net
         assets of any Unrestricted Subsidiary at the time such Unrestricted
         Subsidiary is designated a Restricted Subsidiary; provided, however,
         that in the case of (i) or (ii) above the foregoing sum shall not
         exceed the

                                       74

         amount of Investments previously made (and treated as a Restricted
         Payment) by the Company or any Restricted Subsidiary in such Person or
         Unrestricted Subsidiary, plus

Restricted Subsidiary may take the following actions so long as (with respect to
clauses (ii), (iii), (iv) and (v) below) no Default or Event of Default shall
have occurred and be continuing:

                  (i) the payment of any dividend within 60 days after the date
         of declaration thereof, if at such date of declaration the payment of
         such dividend would have complied with the provisions of paragraph (a)
         above (such payment shall be deemed to have been paid on such date of
         declaration for purposes of the calculation required by paragraph (a)
         above), provided, however, that such dividend (but not the declaration
         thereof) shall be included in the calculation of the amount of
         Restricted Payments;

                  (ii) the purchase, redemption or other acquisition or
         retirement for value of any shares of Capital Stock of the Company in
         exchange for, or out of the net cash proceeds of a substantially
         concurrent issuance and sale (other than to a Restricted Subsidiary)
         of, shares of Qualified Capital Stock of the Company, provided,
         however, that (A) such purchase, redemption or other acquisition or
         retirement shall be excluded in the calculation of the amount of
         Restricted Payments, and (B) the aggregate net cash proceeds (to the
         extent used for such purchase, redemption, acquisition or retirement)
         and the Fair Market Value of such Capital Stock received by the Company
         from such issuance and sale shall be excluded from the calculation of
         amounts available for Restricted Payments under clause (3) of paragraph
         (a) above;

                  (iii) the purchase, redemption, defeasance or other
         acquisition or retirement for value of any Subordinated Indebtedness in
         exchange for, or out of the net cash proceeds of a substantially
         concurrent issuance and sale (other than to a Restricted Subsidiary)
         of, shares of Qualified Capital Stock of the Company, provided,
         however, that (A) such purchase, redemption, defeasance or other
         acquisition or retirement shall be excluded in the calculation of the
         amount of Restricted Payments, and (B) the aggregate net cash proceeds
         (to the extent used for such purchase, redemption, defeasance,
         acquisition or retirement) and the Fair Market Value of such
         Subordinated Indebtedness received by the Company from such issuance
         and sale shall be excluded from the calculation of amounts available
         for Restricted Payments under clause (3) of paragraph (a) above;

                  (iv) the purchase, redemption, defeasance or other acquisition
         or retirement for value of Subordinated Indebtedness in exchange for,
         or out of the net cash proceeds of a substantially concurrent
         incurrence (other than to a Restricted Subsidiary) of, new Subordinated
         Indebtedness so long as (A) the principal amount of
<PAGE>   86
                                       75

         such new Indebtedness does not exceed (1) the principal amount (or, if
         such Subordinated Indebtedness being refinanced was incurred with
         original issue discount, the aggregate accreted value as of the date of
         determination) of the Subordinated Indebtedness being so purchased,
         redeemed, defeased, acquired or retired, plus (2) the lesser of the
         amount of any premium required to be paid in connection with such
         refinancing pursuant to the terms of the Subordinated Indebtedness
         being refinanced or the amount of any premium reasonably determined by
         the Company as necessary to accomplish such refinancing, plus (3) the
         amount of any fees and expenses incurred to accomplish such
         refinancing, (B) such new Subordinated Indebtedness is subordinated to
         the Securities to the same extent as such Subordinated Indebtedness so
         purchased, redeemed, defeased, acquired or retired and (C) such new
         Subordinated Indebtedness has an Average Life equal to or greater than
         the Average Life of the Indebtedness being refinanced and a final
         Stated Maturity of principal later than the final Stated Maturity of
         principal of the Indebtedness being refinanced, provided, however, that
         such purchase, redemption, defeasance or other acquisition or
         retirement shall be excluded in the calculation of the amount of
         Restricted Payments; and

                  (v) the repurchase of Warrants in accordance with the terms of
         the Warrant Agreement, provided, however, that such repurchase shall be
         excluded in the calculation of the amount of Restricted Payments.

                  (c) In computing Consolidated Cash Flow and Consolidated
Interest Expense of the Company under paragraph (a) above, (1) the Company shall
use audited financial statements for the portions of the relevant period for
which audited financial statements are available on the date of determination
and unaudited financial statements and other current financial data based on the
books and records of the Company for the remaining portion of such period and
(2) the Company shall be permitted to rely in good faith on the financial
statements and other financial data derived from the books and records of the
Company that are available on the date of determination. If the Company makes a
Restricted Payment which, at the time of the making of such Restricted Payment,
would in the good faith determination of the Company be permitted under the
requirements of this Indenture, such Restricted Payment shall be deemed to have
been made in compliance with this Indenture notwithstanding any subsequent
adjustments made in good faith to the Company's financial statements affecting
Consolidated Cash Flow and Consolidated Interest Expense of the Company for any
period.

                  SECTION 1012. Limitation on Issuances and Sales of Capital
Stock of Restricted Subsidiaries.

                  The Company (a) shall not permit any Restricted Subsidiary to
issue any Capital Stock (other than to the Company or a Wholly Owned Restricted
Subsidiary) and (b) shall not permit any Person (other than the Company or a
Wholly Owned Restricted Subsidiary) to own any Capital Stock of any Restricted
Subsidiary; provided, however, that this covenant shall not prohibit (i) the
sale or other disposition of all, but not less than all, of

<PAGE>   87
                                       76

the issued and outstanding Capital Stock of any Restricted Subsidiary owned by
the Company and all Restricted Subsidiaries in compliance with the other
provisions of this Indenture and (ii) the ownership by directors of director's
qualifying shares or the ownership by foreign nationals of Capital Stock of any
Restricted Subsidiary, to the extent mandated by applicable law.

                  SECTION 1013.  Limitation on Transactions with Affiliates.

                  The Company shall not, and shall not permit any Restricted

the sale, purchase, exchange or lease of assets, property or services) with, or
for the benefit of, any Affiliate of the Company or any Restricted Subsidiary
(other than the Company or a Wholly Owned Restricted Subsidiary) unless such
transaction is entered into in good faith and (i) such transaction or series of
transactions is fair and reasonable to the Company or such Restricted
Subsidiary, as the case may be, and is on terms that are no less favorable to
the Company or such Restricted Subsidiary, as the case may be, than those that
could have been obtained in an arm's-length transaction with a third party that
is not an Affiliate, (ii) with respect to any transaction or series of related
transactions involving aggregate consideration equal to or greater than
US$5,000,000, the Company shall deliver an Officers' Certificate to the Trustee
certifying that such transaction or series of transactions complies with clause
(i) above and such transaction or series of related transactions has been
approved by a majority of the Disinterested Directors of the Company or, in the
event no members of the Board of Directors of the Company are Disinterested
Directors with respect to such transaction or series of transactions, the
Company shall obtain a written opinion from an internationally recognized United
States, United Kingdom or European investment banking firm to the effect that
such transaction or series of related transactions is fair to the Company or its
Restricted Subsidiary, as the case may be, from a financial point of view and
(iii) with respect to any transaction or series of related transactions
involving aggregate consideration in excess of US$10,000,000, the Board of
Directors shall approve the fairness of such transaction after the Company has
obtained a written opinion from an internationally recognized United States,
United Kingdom or European investment banking firm to the effect set forth in
the preceding clause (ii); provided, however, that no opinion from an investment
banking firm will be required with respect to interconnection agreements entered
into by the Company or any Restricted Subsidiary in the ordinary course of
business and provided further that this covenant shall not restrict (1) the
Company from paying reasonable and customary regular compensation and fees to
directors of the Company or any Restricted Subsidiary who are not employees of
the Company or any Restricted Subsidiary, (2) the performance of the Company's
obligations under agreements existing on the Issue Date and listed on Schedule
II hereto; provided that any amendments or modifications to the terms of such
agreements shall be no less favorable to the Company than the terms existing on
the Issue Date, (3) the grant of stock options or similar rights to employees
and directors of the Company pursuant to plans approved by the Board of
Directors, provided that, in the aggregate, the shares underlying such options
or similar rights issued on or after the Issue Date (exclusive of any


<PAGE>   88
                                       77

shares underlying such options or similar rights required to be issued by law)

in the ordinary course of business in an aggregate amount not to exceed
US$1,000,000 at any one time outstanding and (5) any Restricted Payment

                  SECTION 1014.  Limitation on Liens.

                  The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist
any Lien of any kind (other than Permitted Liens) on or with respect to any of
its property or assets, including any shares of stock or indebtedness of any
Restricted Subsidiary, whether owned at the Issue Date or thereafter acquired,
or any income, profits or proceeds therefrom, or assign or otherwise convey any
right to receive income thereon, unless (x) in the case of any Lien securing
Subordinated Indebtedness, the Securities are secured by a Lien on such
property, assets or proceeds that is senior in priority to such Lien and (y) in
the case of any other Lien, the Securities are equally and ratably secured with
the obligation or liability secured by such Lien.

                  SECTION 1015. Purchase of Securities upon a Change of Control.

                  (a) If a Change of Control shall occur at any time, then each
Holder of Securities shall have the right to require that the Company purchase
such Holder's Securities, in whole or in part in integral multiples of US$1,000
principal amount at final maturity, at a purchase price (the "Change of Control
Purchase Price") in cash in an amount equal to 101% of the Accreted Value
thereof plus accrued interest, if any, to the date of purchase (the "Change of
Control Purchase Date"), in accordance with the procedures set forth in
paragraphs (b) and (c) of this Section (the "Change of Control Offer").

                  (b) Within 15 days following any Change of Control, the
Company shall notify the Trustee thereof and give written notice of such Change
of Control to each Holder of Securities in the manner provided in Section 106,
stating:

                  (1) that a Change in Control has occurred and that such Holder
         has the right to require the Company to repurchase such Holder's
         Securities at the Change of Control Purchase Price;

                  (2) the circumstances and relevant facts regarding such Change
         in Control (including but not limited to information with respect to
         pro forma historical income, cash flow and capitalization after giving
         effect to such Change in Control);

                  (3) the Change of Control Purchase Price and the Change of
         Control Purchase Date, which shall be a Business Day no earlier than 30
         days nor later than 60 days from the date such notice is mailed, or

<PAGE>   89
                                       78

         comply with requirements under the Exchange Act or any applicable
         securities laws or regulations;

                  (4) that all Securities validly tendered will be accepted for
         payment and that any Security not tendered shall continue to accrue
         interest or accrete in value, as the case may be;

                  (5) that, unless the Company defaults in the payment of the
         Change of Control Purchase Price, any Securities accepted for payment
         pursuant to the Change of Control Offer shall cease to accrue interest
         or accrete in value after the Change of Control Purchase Date;

                  (6) the instructions that a Holder of Securities must follow
         to accept a Change of Control Offer or to withdraw such acceptance in
         accordance with paragraph (c) of this Section; and

                  (7) if applicable, that the prohibition under Colombian law
         described in paragraph (f) below is in effect and that the Company is
         making the deposit with the Trustee required by such paragraph (f) and
         stating the date on which the purchase will be completed.

                  (c) Holders electing to have Securities purchased will be
required to surrender such Securities to the Company at the address specified in
the notice at least five Business Days prior to the Change of Control Purchase
Date (or such later date as provided in paragraph (f) below). Holders will be
entitled to withdraw their election if the Company receives, not later than
three Business Days prior to the Change of Control Purchase Date (or such later
date as provided in paragraph (f) below), a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Securities delivered for purchase by the Holder as to which his
election is to be withdrawn and a statement that such Holder is withdrawing his
election to have such Securities purchased. Holders whose Securities are
purchased only in part will be issued new Securities equal in principal amount
to the unpurchased portion of the Securities surrendered.

                  (d) The Company shall comply with any applicable securities
laws and regulations in connection with a Change of Control Offer.

                  (e) The Company shall not enter into any agreement (other than
the Bank Credit Agreement or agreements governing Indebtedness as in effect on
the Issue Date) that would prohibit the Company from making a Change of Control
Offer to purchase the Securities or, if such Change of Control Offer is made, to
pay for the Securities tendered for purchase.

                                       79

                  (f) If any redemption or prepayment of the Securities pursuant
to a Change of Control Offer on or prior to the first anniversary of the Issue
Date is prohibited by Colombian law, and if the Company is required to make a
Change of Control Offer with a Change of Control Purchase Date (determined
pursuant to clause (b)(3) above) on or prior to the first anniversary of the
Issue Date, the Company shall be required to deposit with the Trustee cash in
United States dollars and/or United States Government Obligations in an amount
sufficient (without taking into account the payment of interest thereon) to
acquire all of the Outstanding Securities on the first Business Day after the
first anniversary of the Issue Date. Such funds deposited with the Trustee
(together with any additional funds provided by the Company, if necessary) shall
be used by the Trustee to purchase the Securities on the first Business Day
after the first anniversary of the Issue Date. If the Company shall have (i)
delivered an Opinion of Counsel to the Trustee confirming such prohibition under
Colombian law and (ii) made such deposit with the Trustee prior to such Change
of Control Purchase Date, the Company shall not be in default of its obligations
to make a Change of Control Offer prior to the first Business Day after the
first anniversary of the Issue Date. If the notice sent pursuant to paragraph
(b) above is sent more than 60 days prior to the date of purchase provided in
this paragraph, the Company shall send an additional notice providing the
information required by paragraph (b) not less than 30 nor more than 60 days
prior to the date of purchase provided in this paragraph.

                  (g) If any redemption of the Securities within three years of
the Issue Date resulting in more than 40% of the aggregate principal amount at
maturity of the Securities being redeemed would impose certain deposit
requirements on the Company under Colombian law, the Company shall make such
deposit prior to consummating any Change of Control Offer.

                  SECTION 1016.  Limitation on Sale of Assets.

                  (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any Asset Sale unless (i) the consideration received by
the Company or such Restricted Subsidiary for such Asset Sale is not less than
the Fair Market Value of the assets subject to such Asset Sale (as determined by
the Board of Directors of the Company, whose determination shall be conclusive
and evidenced by a Board Resolution), (ii) the consideration received by the
Company or the relevant Restricted Subsidiary in respect of such Asset Sale
consists of at least 85% cash or Cash Equivalents and (iii) immediately before
and immediately after giving effect to such Asset Sale, no Default or Event of
Default shall have occurred and be continuing or be anticipated to occur.

                  (b) If the Company or any Restricted Subsidiary engages in an
Asset Sale, the Company may use the Net Cash Proceeds thereof, within 12 months
after the later of such Asset Sale or the receipt of such Net Cash Proceeds, to
(i) permanently repay or prepay any then outstanding secured Indebtedness of the
Company under the Bank Credit Agreement or other secured Indebtedness that is
not subordinated to payment of the Securities or Indebtedness of any Restricted
Subsidiary or (ii) invest (or enter into a legally binding


<PAGE>   91
                                       80

agreement to invest) in properties and assets that will be used in businesses of
the Company or its Restricted Subsidiaries, as the case may be, that (x) existed
on the Issue Date or (y) is a Permitted Telecommunications Business. If any such
legally binding agreement to invest such Net Cash Proceeds is terminated, then
the Company may, within 90 days of such termination or within 12 months of such
Asset Sale, whichever is later, invest such Net Cash Proceeds as provided in
clause (i) or (ii) (without regard to the parenthetical contained in such clause
(ii)) above. The amount of such Net Cash Proceeds not so used as set forth above
in this paragraph (b) constitutes "Excess Proceeds."

                  (c) When the aggregate amount of Excess Proceeds exceeds
US$10,000,000, the Company shall, within 15 Business Days, make an offer to
purchase (an "Excess Proceeds Offer") from all Holders of Securities, on a pro
rata basis, in accordance with the procedures set forth below, the maximum
principal amount of Securities that may be purchased with the Excess Proceeds
(rounded down to the nearest multiple of US$1,000). The offer price as to each
Security shall be payable in cash in an amount equal to 100% of the Accreted
Value of such Security plus accrued interest, if any, to the date such Excess
Proceeds Offer is consummated (the "Offered Price"). To the extent that the
aggregate principal amount of Securities tendered pursuant to an Excess Proceeds
Offer is less than the Excess Proceeds, the Company may use such deficiency for
general corporate purposes. If the aggregate principal amount of Securities
validly tendered and not withdrawn by Holders thereof exceeds the Excess
Proceeds, Securities to be purchased shall be selected on a pro rata basis, with
such adjustments as may be deemed appropriate by the Trustee, so that only
Securities in denominations of U.S.$1,000, or integral multiples thereof, shall
be purchased. Upon completion of such Excess Proceeds Offer, the amount of
Excess Proceeds shall be reset to zero.

                  (d) The Company shall, within the time period provided in
paragraph (c) above, notify the Trustee of any Excess Proceeds Offer and shall
give written notice of such Excess Proceeds Offer to each Holder of Securities
in the manner provided in Section 106 stating:

                  (1) that the Holder has the right to require the Company to
         repurchase such Holder's Securities at the Offered Price, subject to
         proration in the event the Excess Proceeds are less than the aggregate
         Offered Price of all Securities tendered;

                  (2) the date of purchase of Securities pursuant to the Excess
         Proceeds Offer (the "Asset Sale Purchase Date"), which shall be no
         earlier than 30 days nor later than 60 days from the date such notice
         is mailed, or such later date as is necessary to comply with
         requirements under the Exchange Act or any applicable securities laws
         or regulations;

                  (3) that any Security not tendered will continue to accrue
         interest or accrete in value, as the case may be;


<PAGE>   92
                                       81

                  (4) that, unless the Company defaults in the payment of the
         Offered Price, any Security accepted for payment pursuant to the Excess
         Proceeds Offer shall cease to accrue interest or accrete in value after
         the Asset Sale Purchase Date;

                  (5) the instructions a Holder must follow to accept an Excess
         Proceeds Offer or to withdraw such acceptance in accordance with
         paragraph (e) of this Section;

                  (6) if applicable, that the prohibition under Colombian law
         described in paragraph (f) below is in effect and that the Company is
         making the deposit with the Trustee required by such paragraph (f) and
         stating the date on which the purchase will be completed; and

                  (7) if applicable, that redemption or repurchase of 40% or
         more of the aggregate principal amount at maturity of the Securities
         would impose certain deposit requirements on the Company under
         Colombian law and describing the proration procedures or deposits with
         the Trustee that the Company may elect, as the case may be, pursuant to
         paragraphs (f) and (g).

                  (e) Holders electing to have Securities purchased will be
required to surrender such Securities to the Company at the address specified in
the notice at least five Business Days prior to the Asset Sale Purchase Date.
Holders will be entitled to withdraw their election if the Company receives, not
later than three Business Days prior to the Asset Sale Purchase Date (or such
later date as provided in paragraph (f) or (g) below, as the case may be), a
telegram, telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Securities delivered for purchase by the
Holder as to which his election is to be withdrawn and a statement that such
Holder is withdrawing his election to have such Securities purchased. Holders
whose Securities are purchased only in part will be issued new Securities equal
in principal amount to the unpurchased portion of the Securities surrendered.

                  (f) If any redemption or prepayment of the Securities pursuant
to an Excess Proceeds Offer on or prior to the first anniversary of the Issue
Date is prohibited by Colombian law, and if the Company is required to make an
Excess Proceeds Offer with an Asset Sale Purchase Date (determined pursuant to
clause (d)(2) above) on or prior to the first anniversary of the Issue Date, the
Company shall be required to deposit with the Trustee cash in United States
dollars and/or United States Government Obligations in an amount sufficient
(without taking into account the payment of interest thereon) to acquire all of
the Securities tendered pursuant to such Excess Proceeds Offer on the first
Business Day after the first anniversary of the Issue Date. Such funds deposited
with the Trustee (together with any additional funds provided by the Company, if
necessary) shall be used by the Trustee to purchase the Securities on the first
Business Day after the first anniversary of the Issue Date. If the Company shall
have (i) delivered an Opinion of Counsel to the Trustee confirming such
prohibition under Colombian law and (ii) made such deposit with the Trustee
prior to


<PAGE>   93
                                       82

such Asset Sale Purchase Date, the Company shall not be in default of its
obligations to make an Excess Proceeds Offer prior to the first Business Day
after the first anniversary of the Issue Date. If the notice sent pursuant to
paragraph (d) above is sent more than 60 days prior to the date of purchase
provided in this paragraph, the Company shall send an additional notice
providing the information required by paragraph (d) not less than 30 nor more
than 60 days prior to the date of purchase provided in this paragraph.

                  (g) If any redemption of the Securities within three years of
the Issue Date resulting in more than 40% of the aggregate principal amount at
maturity of the Securities being redeemed or repurchased would impose certain
deposit requirements on the Company under Colombian law and the Securities
tendered pursuant to an Excess Proceeds Offer with an Asset Sale Purchase Date
(determined pursuant to clause (d)(2) above) on or prior to the third
anniversary of the Issue Date exceed 40% of the aggregate principal amount at
maturity of the Securities (or such lesser amount that, when added to the
Securities previously redeemed or purchased, would exceed 40% of the aggregate
principal amount at maturity of the Securities), the Company may (i) make the
deposit required by the Central Bank and thereafter complete the purchase of the
Securities pursuant to the Excess Proceeds Offer or (ii) purchase pro rata 40%
of the aggregate principal amount at maturity of the Securities (or such lesser
amount that would result, together with any prior redemption or purchase, in an
aggregate of 40% of the aggregate principal amount at maturity of the Securities
having been redeemed or purchased) and, in lieu of the purchase of the remainder
of such tendered Securities, deposit with the Trustee cash in United States
dollars and/or United States Government Obligations in an amount sufficient
(without taking into account the payment of interest thereon) to purchase the
remaining Securities on the first Business Day after the third anniversary of
the Issue Date at the Offered Price (which shall be calculated with respect to
the actual date of purchase provided in this paragraph (g)). Such funds
deposited with the Trustee (together with any additional funds provided by the
Company, if necessary) shall be used by the Trustee to redeem the Securities on
the first Business Day after the third anniversary of the Issue Date. If the
Company shall have (i) delivered an Opinion of Counsel to the Trustee confirming
such deposit requirement under Colombian law and (ii) made such deposit with the
Trustee prior to the applicable Asset Sale Purchase Date, the Company shall not
be in default of its obligations to make an Excess Proceeds Offer prior to the
first Business Day after the third anniversary of the Issue Date. The Company
shall promptly notify the Holders of any election to make the deposit with the
Trustee provided in this paragraph, providing information with respect to any
proration and the date of, and procedures for, the purchase of any remaining
Securities tendered pursuant to the Excess Proceeds Offer. If the notice sent
pursuant to paragraph (d) above is sent more than 60 days prior to the date of
purchase provided in this paragraph, the Company shall send an additional notice
providing the information required by paragraph (d) not less than 30 nor more
than 60 days prior to the date of purchase provided in this paragraph.

                                       83

                  The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, enter into any Sale and Leaseback
Transaction with respect to any property or assets (whether owned at the date
hereof or hereafter acquired), unless the sale or transfer of such property or
assets to be leased is treated as an Asset Sale and the Company complies with
Section 1016 with respect thereto.

                  SECTION 1018.  Limitation on the Activities of the Company.

                  The Company and its Restricted Subsidiaries shall not engage
in any business other than the business of the Company or its Restricted
Subsidiaries existing on the Issue Date and any Permitted Telecommunications
Business and the making of Investments permitted by Section 1011.

                  SECTION 1019. Limitation on Dividends and Other Payment
Restrictions Affecting Restricted Subsidiaries.

                  The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to (a) pay dividends, in cash or otherwise,
or make any other distributions on or in respect of its Capital Stock, (b) pay
any Indebtedness owed to the Company or any other Restricted Subsidiary that,
directly or indirectly, owns any Capital Stock of such Restricted Subsidiary,
(c) make loans or advances to the Company or any other Restricted Subsidiary
that, directly or indirectly, owns any Capital Stock of such Restricted
Subsidiary or (d) transfer any of its properties or assets to the Company or any
other Restricted Subsidiary that, directly or indirectly, owns any Capital Stock
of such Restricted Subsidiary (other than customary restrictions on transfers of
property subject to a Lien permitted under this Indenture that would not
materially adversely affect the Company's ability to satisfy its obligations
under the Securities and this Indenture), except, in each case, for such
encumbrances or restrictions existing under or by reason of (i) the Securities
and this Indenture, (ii) any agreement in effect on the Issue Date, (iii)
applicable law, (iv) customary provisions restricting subletting or assignment
of any lease or assignment of any other contract to which the Company or any
Restricted Subsidiary is a party or to which any of their respective properties
or assets are subject, (v) any agreement or other instrument of a Person, or
pertaining to property or assets, acquired by the Company or any Restricted
Subsidiary in existence at the time of such acquisition (but not created in
contemplation thereof), which encumbrance or restriction is not applicable to
any Person, or the properties or assets of any Person, other than the Person, or
the property or assets of the Person, so acquired, (vi) any Lien permitted under
Section 1014, (vii) any encumbrance or restriction contained in contracts for
sales of assets or Capital Stock of a person with respect to the assets or
Capital Stock to be sold (or the assets owned by the Person whose Capital Stock
is to be sold) pursuant to such contract that terminates upon the earlier of the
termination of such agreement or the consummation of such sale and (viii) any
encumbrance or restriction existing under any agreement that extends, renews,
refinances or replaces the agreements containing the encumbrances or


<PAGE>   95
                                       84

restrictions in the foregoing clauses (i), (ii) and (v); provided that the terms
and conditions of any such encumbrances or restrictions are not materially less
favorable to the Holders of the Securities than those under or pursuant to the
agreement so extended, renewed, refinanced or replaced.

                  SECTION 1020.  Payment of Additional Amounts.

                  (a) Any and all payments made by the Company under the
Securities will be made free and clear of and without deduction for or on
account of any and all present or future taxes, levies, imposts, deductions,
charges or withholdings and all liabilities with respect thereto imposed by the
Republic of Colombia or any political subdivision thereof excluding any taxes,
levies, imposts, deductions, charges or withholdings and all liability with
respect thereto (i) resulting from the Holder having some connection with the
Republic of Colombia or any political subdivision thereof other than the mere
holding of or enforcement of or receipt of any payment with respect to such
Security, (ii) the payment of which may be avoided by the Holder complying with
any certification, declaration or other reporting requirement concerning the
nationality, residence, identity or connection with any taxing authority of such
Holder as the beneficial owner of such Security, (iii) that would not have been
imposed but for the presentation (where presentation is required) of such
Security for payment more than 30 days after the date such payment became due
and payable or was duly provided for, whichever occurs later, (iv) in the nature
of estate, inheritance, gift, sale, transfer, personal property or similar taxes
or (v) imposed on or with respect to any payment by the Company to the Holder if
such Holder is a fiduciary or partnership or person other than the sole
beneficial owner of such payment to the extent such tax, levy, impost,
deduction, charge or withholding would not have been imposed on a beneficiary or
settlor with respect to such fiduciary, member of such partnership or the
beneficial owner of such payment had such beneficiary, settlor, member or
beneficial owner been the Holder of such Security (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
referred to collectively or individually as "Colombian Withholding Taxes"). If
the Company is required by law to deduct any Colombian Withholding Taxes from or
in respect of any sum payable under a Security, the sum payable thereunder shall
be increased by the amount necessary so that after making all required
deductions the Holder will receive an amount equal to the sum it would have
received had no such deductions been made (such additional amounts to be paid by
the Company in accordance with the foregoing being "Additional Amounts").

                  (b) At least 30 calendar days prior to each date on which any
payment under or with respect to the Securities is due and payable, if the
Company will be obligated to pay Additional Amounts with respect to such
payment, the Company will deliver to the Trustee an Officers' Certificate (i)
stating the fact that such Additional Amounts will be payable and the amounts so
payable; (ii) certifying the amount required to be withheld on such date; (iii)
certifying that the Company shall withhold such amount on such date and shall
pay such amount with any required penalty or interest to the appropriate
governmental authorities; and (iv) setting forth such other information
necessary to enable the Trustee to


<PAGE>   96
                                       85

pay such Additional Amounts to Holders on the payment date. The Company agrees
to indemnify each of the Trustee and Paying Agents for, and to hold each
harmless against, any loss, liability or expense reasonably incurred without
negligence or bad faith on its part arising out of or in connection with actions
taken or omitted by it in reliance on any certificate furnished pursuant to this
Section 1020 or the failure of the Company to furnish any such certificate.
Whenever in this Indenture there is mentioned, in any context, the payment of
principal, interest, if any, or any other amount payable under or with respect
to any Security or Securities, such mention shall be deemed to include mention
of the payment of Additional Amounts provided for in this Section 1020, to the
extent that, in such context, Additional Amounts are, were or would be payable
in respect thereof pursuant to the provisions of this Section 1020 and express
mention of the payment of Additional Amounts (if applicable) in any provisions
hereof shall not be construed as excluding Additional Amounts in those
provisions hereof where such express mention is not made (if applicable).

                  (c) The obligations of the Company under this Section 1020
shall survive the termination of this Indenture, the resignation or removal of
the Trustee or any Paying Agent and the payment of all amounts under or with
respect to the Securities.

                  SECTION 1021.  Waiver of Certain Covenants.

                  The Company may omit in any particular instance to comply with
any term, provision or condition set forth in Section 803 or Section 1007 or
Sections 1010 through 1014, inclusive, or Sections 1017 through 1019, inclusive,
if before or after the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities, by Act of such
Holders, waive such compliance in such instance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

                  SECTION 1101.  Mandatory and Optional Redemption.

                  (a) The Company shall redeem 50% of the original aggregate
principal amount at maturity of the Securities on March 15, 2003 at 100% of the
principal amount thereof, together with accrued and unpaid interest to the
redemption date, on a pro rata basis from the Holders of the Securities at the
close of business on March 1, 2003.

                  (b) The Securities may be redeemed at the election of the
Company, as a whole or from time to time in part, at any time. In addition, at
any time prior to March 15,


<PAGE>   97
                                       86

1999, the Company may redeem up to 33% of the original aggregate principal
amount at maturity of the Securities within 45 days of one or more Public Equity
Offerings with the net proceeds of such offering at a redemption price equal to
114% of the Accreted Value thereof, provided that no less than 67% of the
original aggregate principal amount at maturity of the Notes remain outstanding.
In each case, redemption shall be subject to the conditions and at the
Redemption Prices specified in the form of Security, together with accrued
interest, if any, to the Redemption Date.

                  (c) If, as a result of any change in, or amendment to, the
laws (including any regulations promulgated thereunder) of the Republic of
Colombia (or any political subdivision or taxing authority thereof or therein),
or any change in, or amendment to, any official position regarding the
application or interpretation of such laws or regulations, which change or
amendment is announced or becomes effective on or after the Issue Date, the
Company has become or would be obligated to pay, on any date on which any amount
would be payable under or with respect to the Securities, any Additional Amounts
in accordance with Section 1020 hereof, then the Company may, at its option,
redeem the Securities, as a whole but not in part, at any time at a redemption
price equal to 100% of the Accreted Value thereof, together with accrued and
unpaid interest thereon, if any, to the redemption date.

                  SECTION 1102.  Applicability of Article.

                  Redemption of Securities at the election of the Company or
otherwise, as permitted or required by any provision of this Indenture, shall be
made in accordance with such provision and this Article.

                  SECTION 1103.  Notice to Trustee of Redemption.

                  (a) In the case of the mandatory redemption pursuant to
paragraph (a) of Section 1101, the Company shall, at least 60 days prior to the
Redemption Date (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee of such Redemption Date and of the principal amount of
Securities to be redeemed and shall deliver to the Trustee such documentation
and records as shall enable the Trustee to select the Securities to be redeemed
pro rata pursuant to Section 1104.

                  (b) The election of the Company to redeem any Securities
pursuant to paragraph (b) or (c) of Section 1101 shall be evidenced by a Board
Resolution. In case of any redemption at the election of the Company, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities to
be redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to
Section 1104.

                                       87

                  SECTION 1104. Selection by Trustee of Securities to Be
Redeemed.

                  If less than all the Securities are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities not
previously called for redemption, by such method as the Trustee shall deem fair
and appropriate (or, in the case of a mandatory redemption pursuant to paragraph
(a) of Section 1101, on a pro rata basis with such adjustments as may be deemed
appropriate by the Trustee to comply with the proviso below) and which may
provide for the selection for redemption of portions of the principal of
Securities; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Security not redeemed to less than
US$1,000.

                  The Trustee shall promptly notify the Company in writing of
the Securities selected for redemption and, in the case of any Securities
selected for partial redemption, the principal amount thereof to be redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to redemption of Securities shall
relate, in the case of any Security redeemed or to be redeemed only in part, to
the portion of the principal amount of such Security which has been or is to be
redeemed.

                  SECTION 1105.  Notice of Redemption.

                  Notice of redemption shall be given in the manner provided for
in Section 106 not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed. The notice if given in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice. In any case, failure to give
such notice or any defect in the notice to the Holder of any Security designated
for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security.

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price and the amount of accrued interest to
         the Redemption Date payable as provided in Section 1107, if any,

                  (3) if less than all Outstanding Securities are to be
         redeemed, the identification (and, in the case of a partial redemption,
         the principal amounts) of the particular Securities to be redeemed,

                  (4) in case any Security is to be redeemed in part only, the
         notice which relates to such Security shall state that on and after the
         Redemption Date, upon


<PAGE>   99
                                       88

         surrender of such Security, the holder will receive, without charge, a
         new Security or Securities of authorized denominations for the
         principal amount thereof remaining unredeemed,

                  (5) that on the Redemption Date the Redemption Price (and
         accrued interest, if any, to the Redemption Date payable as provided in
         Section 1107) will become due and payable upon each such Security, or
         the portion thereof, to be redeemed, and that interest thereon will
         cease to accrue on and after said date, and

                  (6) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price and accrued interest,
         if any.

                  Notice of redemption of Securities to be redeemed shall be
given by the Company or, at the Company's request, by the Trustee in the name
and at the expense of the Company.

                  SECTION 1106.  Deposit of Redemption Price.

                  On or prior to 10:00 a.m. (New York City time) on any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of, and accrued interest on, all the Securities which are to be
redeemed on that date.

                  SECTION 1107.  Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified (together with accrued
interest, if any, to the Redemption Date), and from and after such date (unless
the Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to accrete in value or bear interest. Upon
surrender of any such Security for redemption in accordance with said notice,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
309.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal (and premium, if any)
shall, until paid, bear interest, or the Security shall accrete in value, as the
case may be, from the Redemption Date at the rate borne by the Securities.

                  SECTION 1108.  Securities Redeemed in Part.

                  Any Security which is to be redeemed only in part shall be
surrendered at the office or agency of the Company maintained for such purpose
pursuant to Section 1002 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of like tenor and form, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                       DEFEASANCE AND COVENANT DEFEASANCE

                  SECTION 1301. Company's Option to Effect Defeasance or
Covenant Defeasance.

                  The Company may, at its option by Board Resolution, at any
time, with respect to the Securities, elect to have Section 1302 or Section 1303
be applied to all Outstanding Securities upon compliance with the conditions set
forth below in this Article Thirteen.

                  SECTION 1302.  Defeasance and Discharge.

                  Upon the Company's exercise under Section 1301 of the option
applicable to this Section 1302, the Company shall be deemed to have been
discharged from its obligations with respect to all Outstanding Securities on
the date the conditions set forth in Section 1304 are satisfied (hereinafter,
"legal defeasance"). For this purpose, such legal defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities, which shall thereafter be deemed to
be "Outstanding" only for the purposes of Section 1305 and the other Sections of
this Indenture referred to in (A) and (B) below, and to have satisfied all its
other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging the same), except for the following,
which shall survive until otherwise terminated or discharged hereunder: (A) the
rights of Holders of Outstanding Securities to receive, solely from the trust
fund


<PAGE>   101
                                       90

described in Section 1304 and as more fully set forth in such Section, payments
in respect of the principal of (and premium, if any, on) and interest on such
Securities when such payments are due, (B) the Company's obligations with
respect to such Securities under Sections 304, 305, 308, 1002 and 1003, (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (D)
this Article Thirteen. Subject to compliance with this Article Thirteen, the
Company may exercise its option under this Section 1302 notwithstanding the
prior exercise of its option under Section 1303 with respect to the Securities.

                  SECTION 1303.  Covenant Defeasance.

                  Upon the Company's exercise under Section 1301 of the option
applicable to this Section 1303, the Company shall be released from its
obligations under any covenant contained in Section 801(3) and Section 801(4)
and Section 803 and in Sections 1007 through 1019, inclusive, and the operation
of Sections 501(4) (to the extent it relates to Section 801(3), Section 801(4),
Section 803 and Sections 1007 through 1019, inclusive), 501(8) with respect to
Subsidiaries only) and 501(9) (with respect to Subsidiaries only) with respect
to the Outstanding Securities on and after the date the conditions set forth
below are satisfied (hereinafter, "covenant defeasance"), and the Securities
shall thereafter be deemed not to be "Outstanding" for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "Outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to the Outstanding
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 501(4), but,
except as specified above, the remainder of this Indenture and such Securities
shall be unaffected thereby.

                  SECTION 1304. Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of either
Section 1302 or Section 1303 to the Outstanding Securities:

                  (1) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 607 who shall agree to comply with the
         provisions of this Article Thirteen applicable to it) as trust funds in
         trust for the purpose of making the following payments, specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of such Securities, (A) cash in United States dollars, or (B)
         U.S. Government Obligations which through the scheduled payment of
         principal and interest in respect thereof in accordance with their
         terms will provide, not later than


<PAGE>   102
                                       91

         one day before the due date of any payment, money in an amount, or (C)
         a combination thereof, sufficient, in the opinion of a nationally
         recognized firm of independent public accountants expressed in a
         written certification thereof delivered to the Trustee, to pay and
         discharge, and which shall be applied by the Trustee (or other
         qualifying trustee) to pay and discharge, (i) the principal of (and
         premium, if any) and interest on the Outstanding Securities on the
         Stated Maturity (or Redemption Date, if applicable) of such principal
         (and premium, if any) or installment of interest and (ii) any mandatory
         redemption or analogous payments applicable to the Outstanding
         Securities on the day on which such payments are due and payable in
         accordance with the terms of this Indenture and of such Securities;
         provided that the Trustee shall have been irrevocably instructed to
         apply such cash in United States dollars or the proceeds of such U.S.
         Government Obligations to said payments with respect to the Securities;
         and provided further that upon the effectiveness of this Section 1304,
         the cash in United States dollars or U.S. Government Obligations
         deposited shall not be subject to the rights of the Banks pursuant to
         the provisions of Article Fourteen. Before such a deposit, the Company
         may give to the Trustee, in accordance with Section 1103 hereof, a
         notice of its election to redeem all of the Outstanding Securities at a
         future date in accordance with Article Eleven hereof, which notice
         shall be irrevocable. Such irrevocable redemption notice, if given,
         shall be given effect in applying the foregoing. For this purpose,
         "U.S. Government Obligations" means securities that are (x) direct
         obligations of the United States of America for the timely payment of
         which its full faith and credit is pledged or (y) obligations of a

         instrumentality of the United States of America the timely payment of

         obligation by the United States of America, which, in either case, are
         not callable or redeemable at the option of the issuer thereof, and
         shall also include a depository receipt issued by a bank (as defined in
         Section 3(a)(2) of the Securities Act of 1933, as amended), as
         custodian with respect to any such U.S. Government Obligation or a
         specific payment of principal of or interest on any such U.S.
         Government Obligation held by such custodian for the account of the
         holder of such depository receipt, provided that (except as required by
         law) such custodian is not authorized to make any deduction from the
         amount payable to the holder of such depository receipt from any amount
         received by the custodian in respect of the U.S. Government Obligation
         or the specific payment of principal of or interest on the U.S.
         Government Obligation evidenced by such depository receipt.

                  (2) No (a) Default in the payment of principal of or premium,
         if any, or interest on any Security or a Default resulting from the
         occurrence of a Default specified in Section 501(8) or (9) (without
         regard to any passage of time specified therein) or (b) Event of
         Default with respect to the Securities (other than as a result of a
         breach of the provisions of Article Eight arising from a merger or
         consolidation occurring contemporaneously with such defeasance) shall
         have occurred and be continuing on the date of, or immediately after,
         such deposit or, insofar as paragraphs (8) and (9) of Section 501
         hereof are concerned, at any time during the


<PAGE>   103
                                       92

         period ending on the 91st day after the date of such deposit (it being
         understood that this condition shall not be deemed satisfied until the
         expiration of such period).

                  (3) Such legal defeasance or covenant defeasance shall not
         result in a breach or violation of, or constitute a default under, any
         material agreement or instrument to which the Company is a party or by
         which it is bound.

                  (4) In the case of an election under Section 1302, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (x) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (y) since May 31, 1996, there has
         been a change in the applicable federal income tax law, in either case
         to the effect that, and based thereon such opinion shall confirm that,
         the Holders of the Outstanding Securities will not recognize income,
         gain or loss for federal income tax purposes as a result of such
         defeasance and will be subject to federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such defeasance had not occurred.

                  (5) In the case of an election under Section 1303, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of the Outstanding Securities will not recognize
         income, gain or loss for federal income tax purposes as a result of
         such covenant defeasance and will be subject to federal income tax on
         the same amounts, in the same manner and at the same times as would
         have been the case if such covenant defeasance had not occurred.

                  (6) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to either the legal
         defeasance under Section 1302 or the covenant defeasance under Section
         1303 (as the case may be) have been complied with.

                  SECTION 1305. Deposited Money and U.S. Government Obligations
to Be Held in Trust; Other Miscellaneous Provisions.

                  Subject to the provisions of the last paragraph of Section
1003, all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 1305, the "Trustee") pursuant to Section 1304 in
respect of the Outstanding Securities shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.


<PAGE>   104
                                       93

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Governmental
Obligations deposited pursuant to Section 1304 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the Outstanding Securities.

                  Anything in this Article Thirteen to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon Company Request any money or U.S. Government Obligations held by it as
provided in Section 1304 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance, as applicable, in accordance with this Article.

                  SECTION 1306.  Reinstatement.

                  If the Trustee or any Paying Agent is unable to apply any
money in accordance with Section 1305 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 1302 or 1303, as the case may be, until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 1305; provided, however, that if the Company makes any payment of
principal of (or premium, if any) or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held by
the Trustee or Paying Agent.

of such additional interest will increase by an additional one-half of one
percent per annum for each subsequent 90-day period until such Registration
Default has been cured, payable in cash semiannually, in arrears, on March 15
and September 15 of each year; provided, however, that in no event shall the
rate of such additional interest be more than one and one-half of one percent.
Upon the cure of all applicable Registration Defaults, such additional interest
shall cease to accrue.

                  Any and all payments made by the Company under this Note will
be made free and clear of and without deduction for or on account of any and all
present or future taxes, levies, imposts, deductions, charges or withholdings
and all liabilities with respect thereto imposed by the Republic of Colombia or
any political subdivision thereof excluding any taxes, levies, imposts,
deductions, charges or withholdings and all liability with respect thereto (i)
resulting from the Holder having some connection with the Republic of Colombia
or any political subdivision thereof other than the mere holding of or
enforcement of or receipt of any payment with respect to such Note, (ii) the
payment of which may be avoided by the Holder complying with any certification,
declaration or other reporting requirement concerning the nationality,
residence, identity or connection with any taxing authority of such Holder as
the beneficial owner of such Note, (iii) that would not have been imposed but
for the presentation (where presentation is required) of such Note for payment
more than 30 days after the date such payment became due and payable or was duly
provided for, whichever occurs later, (iv) in the nature of estate, inheritance,
gift, sale, transfer, personal property or similar taxes or (v) imposed on or
with respect to any payment by the Company to the Holder if such Holder is a
fiduciary or partnership or person other than the sole beneficial owner of such
payment to the extent such tax, levy, impost, deduction, charge or withholding
would not have been imposed on a beneficiary or settlor with respect to such
fiduciary, member of such partnership or the beneficial owner of such payment
had such beneficiary, settlor, member or beneficial owner been the Holder of
such Note (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being referred to collectively or individually as
"Colombian Withholding Taxes"). If the Company is required by law to deduct any
Colombian Withholding Taxes from or in respect of any sum payable under this
Note, the sum payable hereunder shall be increased by the amount


<PAGE>   114
                                       A-6

necessary so that after making all required deductions the Holder will receive
an amount equal to the sum it would have received had no such deductions been
made.

                  From and after March 15, 2001, interest on this Note will
accrue from the most recent date to which interest has been paid [on this Note
or the Note surrendered in Exchange herefor]* or, if no interest has been paid,
from March 15, 2001; provided that, if there is no existing default in the
payment of interest and if this Note is authenticated between a Regular Record
Date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such Interest Payment Date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

                  The Company shall pay interest on overdue principal and
premium, if any, and interest on overdue installments of interest, to the extent
lawful, at a rate per annum equal to the rate of interest applicable to the
Notes.

2.  Method of Payment.

                  The Company will pay interest (except Defaulted Interest) on
the principal amount of the Notes on each March 15 and September 15 to the
persons who are Holders (as reflected in the Security Register at the close of
business on the March 1 and September 1 immediately preceding the Interest
Payment Date), in each case, even if the Note is cancelled on registration of
transfer or registration of exchange after such record date; provided that, with
respect to the payment of principal, the Company will make payment to the Holder
that surrenders this Note to any Paying Agent on or after March 15, 2004.

                  The Company will pay principal, premium, if any, and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. However, the Company may pay principal,
premium, if any, and interest by its check payable in such money. The Company
may mail an interest check to a Holder's registered address (as reflected in the
Security Register). The Company may also make any payment of monies required to
be deposited with the Trustee on account of principal of, or premium, if any, or
interest on, this Note by wire transfer in immediately available funds to an
account designated by the Trustee on or before the date such monies are to be
paid to the Holder. If a payment date is a date other than a Business Day,
payment may be made on the next succeeding day that is a Business Day and no
interest shall accrue for the intervening period.

3.   Priority of Concession Proceeds.

                  Prior to the Pledge Effective Date (as defined in the
Indenture), the indebtedness evidenced by the Notes is, to the extent and in the
manner provided in the Indenture, subject in right of payment to the prior
payment in full of indebtedness under the Bank Facility to the extent of the

action as may be necessary or appropriate in order to effectuate such provisions
and (c) appoints the Trustee his attorney-in-fact for such purpose.

Subsidiary or any Affiliate of any of them may act as Paying Agent, Registrar or
co-registrar.

5.  Indenture; Limitations.

                  The Company issued the Notes under an Indenture dated as of
June 1, 1996 (the "Indenture"), between the Company and The Bank of New York, as
trustee (the "Trustee"). Capitalized terms herein are used as defined in the
Indenture unless otherwise indicated. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the Trust Indenture Act for a statement of all
such terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this Note and the terms of the Indenture, the
terms of the Indenture shall control.

                  The Notes are general unsecured obligations of the Company.
The Indenture limits the aggregate principal amount of the Notes to
US$190,745,000.

6.  Redemption.

original aggregate principal amount at maturity of the Notes on March 15, 2003
at 100% of the principal amount thereof, together with accrued and unpaid
interest to the redemption date, on a pro rata basis from the Holders of the
Notes at the close of business on March 1, 2003.

the Accreted Value of Notes so redeemed; provided that no less than 67% of the
original aggregate principal amount at maturity of the Notes remains
outstanding.

                  Optional Redemption for Changes in Colombian Withholding Tax.
The Notes may be redeemed at the election of the Company if, as a result of any
change in, or amendment to, the laws (including any regulations promulgated
thereunder) of Colombia (or any political subdivision or taxing authority
thereof or therein), or any change in, or amendment to, any official position
regarding the application or interpretation of such laws or regulations, which
change or amendment is announced or becomes effective on or after the Issue
Date, the Company has become or would be obligated to pay, on any date on which
any amount would be payable under or with respect to the Securities, any

Withholding Tax, then the Company may, at its option, redeem the Notes, as a
whole but not in part, at any time at a redemption price equal to 100% of the
Accreted Value thereof, together with accrued and unpaid interest thereon, if
any, to the redemption date.

                  Notice of a redemption will be mailed at least 30 days but not
more than 60 days before the Redemption Date to each Holder of Notes to be
redeemed at such Holder's last address as it appears in the Security Register.
Notes in original denominations larger than US$1,000 principal amount at
maturity may be redeemed in part in integral multiples of US$1,000 principal
amount at maturity. On and after the Redemption Date, interest ceases to accrue
on Notes or portions of Notes called for redemption, unless the Company defaults
in the payment of the Redemption Price.

7.  Repurchase upon a Change of Control.

have the right to require that the Company repurchase such Holder's Notes, in
whole or in part, in integral multiples of $1,000 principal amount at final
Maturity, at a purchase price in cash in an amount equal to 101% of the Accreted
Value thereof, plus accrued interest (if any) to the date of purchase (the
"Change of Control Purchase Price").

                  A notice of each Change in Control will be mailed within 15
days after such Change of Control occurs to each Holder at his last address as
it appears in the Security Register. On and after the Change of Control Payment
Date, interest ceases to accrue on Notes or portions of Notes surrendered for
purchase by the Company, unless the Company defaults in the payment of the
Change of Control Purchase Price.

8.  Denominations; Transfer; Exchange.

                  The Notes are in registered form without coupons, in
denominations of $1,000 principal amount at maturity and multiples of $1,000 in
excess thereof. A Holder may register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not register the transfer or exchange of any Notes selected for redemption
(except the unredeemed portion of any Note being redeemed in part). Also, it
need not register the transfer or exchange of any Notes for a period of 15 days
before a selection of Notes to be redeemed is made.

9.  Persons Deemed Owners.

                  A Holder may be treated as the owner of a Note for all
purposes.

10.  Unclaimed Money.

                  If money for the payment of principal, premium, if any, or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company at its request. After that, Holders entitled
to the money must look to the Company for payment, unless an abandoned property
law designates another Person, and all liability of the Trustee and such Paying
Agent with respect to such money shall cease.

11.  Amendment; Supplement; Waiver.

outstanding, and any existing default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount at final Maturity of the Notes then outstanding. Without notice to or the

provided such change does not materially adversely affect the rights of any
Holder.

Company contained in any agreement or instrument evidencing any such
Indebtedness; (g) one or more final judgments or orders shall be rendered
against the Company or any Subsidiary for the payment of money, either

                    Discount Notes due 2004 (the "Securities")

Ladies and Gentlemen:

         In connection with our proposed purchase of $____________ aggregate
principal amount of the Securities:

         1. We understand that the Securities have not been registered under the
     Securities Act of 1933, as amended (the "Securities Act"), and may not be
     sold except as permitted in the following sentence. We agree on our own
     behalf and on behalf of any investor account for which we are purchasing
     the Securities to offer, sell or otherwise transfer such Securities prior
     to the date which is three years after the later of the date of original
     issue and the last date on which the Company or any affiliate of the
     Company was the owner of such Securities, or any predecessor thereto (the
     "Resale Restriction Termination Date") only (a) to the Company, (b)
     pursuant to a registration statement which has been declared effective
     under the Securities Act, (c) for so long as the Securities are eligible
     for resale pursuant to Rule 144A under the Securities Act, to a person we
     reasonably believe is a qualified institutional buyer under Rule 144A (a
     "QIB") that purchases for its own account or for the account of a QIB to
     whom notice is given that the transfer is being made in reliance on Rule
     144A, (d) pursuant to offers and sales to non-U.S. Persons that occur
     outside the United States within the meaning of Regulation S under the
     Securities Act, (e) to an institutional "accredited investor" within the
     meaning of subparagraph (a)(1), (2), (3)
<PAGE>   126
                                       C-2

     or (7) of Rule 501 under the Securities Act that is acquiring the
     Securities for its own account or for the account of such an institutional
     "accredited investor" for investment purposes and not with a view to, or
     for offer or sale in connection with, any distribution thereof in violation
     of the Securities Act or (f) pursuant to any other available exemption from
     the registration requirements of the Securities Act, subject in each of the
     foregoing cases to any requirement of law that the disposition of our
     property and the property of such investor account or accounts be at all
     times within our or their control and to compliance with any applicable
     state securities laws. The foregoing restrictions on resale will not apply
     subsequent to the Resale Restriction Termination Date. If any resale or
     other transfer of the Securities is proposed to be made pursuant to clause
     (e) above prior to the Resale Restriction Termination Date, the transferor
     shall deliver a letter from the transferee substantially in the form of
     this letter to the Trustee, which shall provide, among other things, that
     the transferee is an institutional "accredited investor" within the meaning
     of subparagraph (a)(1), (2), (3) or (7) or Rule 501 under the Securities
     Act and that it is acquiring such Securities for investment purposes and
     not for distribution in violation of the Securities Act. We acknowledge
     that the Company and the Trustee reserve the right prior to any offer, sale
     or other transfer prior to the Resale Restriction Termination Date of the
     Securities pursuant to clauses (d), (e) and (f) above to require the
     delivery of an opinion of counsel, certifications and/or other information
     satisfactory to the Company and the Trustee.

         2. We are an institutional "accredited investor" (as defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act)
     purchasing for our own account or for the account of such an institutional
     "accredited investor," and we are acquiring the Securities for investment
     purposes and not with a view to, or for offer or sale in connection with,
     any distribution in violation of the Securities Act and we have such
     knowledge and experience in financial and business matters as to be capable
     of evaluating the merits and risks of our investment in the Securities, and
     we and any accounts for which we are acting are each able to bear the
     economic risk of our or its investment.

         3. We are acquiring the Securities purchased by us for our own account
     or for one or more accounts as to each of which we exercise sole investment
     discretion.

         4. We acknowledge and agree that, as specified on the face of the
     Securities, (i) the issuance of the Securities has been approved by the
     Colombian Superintendency of Corporations (Superintendencia de Sociedades),
     but that such approval does not imply an approval of the quality of the
     Securities, and (ii) the Securities may not be offered or sold in the
     Republic of Colombia.

Securities, Inc. (the "Registration Rights Agreement"). In the event that either
(a) the Exchange Offer Registration Statement (as such term is defined in the
Registration Rights Agreement) is not filed with the Securities and Exchange
Commission on or prior to the 60th calendar day following the date of original
issue of the Notes, (b) the Exchange Offer Registration Statement has not been
declared effective on or prior to the 150th calendar day following the date of

in the Registration Rights Agreement) is not declared effective on or prior to
the 210th calendar day following the date of original issue of the Notes, or (d)
the Exchange Offer Registration Statement or the Shelf Registration Statement is
declared effective, but thereafter ceases to be effective or usable except as
provided in Section 2(d)(ii) of the Registration Rights Agreement (each such
event referred to in clause (a) through (d) above, a "Registration Default")
interest (in addition to the accrual of original issue discount during the
period ending March 15, 2001 and in addition to the interest otherwise due on
the Notes after such date) will accrue on this Note at a rate of one-half of one
percent per annum of the Accreted Value on the immediately preceding semiannual
accrual date (for purposes of this paragraph, "semiannual accrual date" means
each March 15 or September 15 of each year (or, if such immediately preceding
March 15 or September 15 occurs before September 15, 1996 at a rate of one-half
of one percent of the Accreted Value of this Note on June 7, 1996)) with respect
to the first 90-day period following such Registration Default, and the amount
of such additional interest will increase by an additional one-half of one
percent per annum for each subsequent 90-day period until such Registration
Default has been cured, payable in cash semiannually, in arrears, on March 15
and September 15 of each year; provided, however, that in no event shall the
rate of such additional interest be more than one and one-half of one percent.
Upon the cure of all applicable Registration Defaults, such additional interest
shall cease to accrue.

                  Any and all payments made by the Company under this Note will
be made free and clear of and without deduction for or on account of any and all
present or future taxes, levies, imposts, deductions, charges or withholdings
and all liabilities with respect thereto imposed by the Republic of Colombia or
any political subdivision thereof excluding any taxes, levies, imposts,
deductions, charges or withholdings and all liability with respect thereto (i)
resulting from the Holder having some connection with the Republic of Colombia
or any political subdivision thereof other than the mere holding of or
enforcement of or receipt of any payment with respect to such Note, (ii) the
payment of which may be avoided by the Holder complying with any certification,
declaration or other reporting requirement concerning the nationality,
residence, identity or connection with any taxing authority of such Holder as
the beneficial owner of such Note, (iii) that would not have been imposed but
for the presentation (where presentation is required) of such Note for payment
more than 30 days after the date such payment became due and payable or was duly
provided for, whichever occurs later, (iv) in the nature of estate, inheritance,
gift, sale, transfer, personal property or similar taxes or (v) imposed on or
with respect to any payment by the Company to the Holder if such Holder is a
fiduciary or partnership or person other than the sole beneficial owner of such
payment to the extent such tax, levy, impost, deduction, charge or withholding
would not have been imposed on a beneficiary or settlor with respect to such
fiduciary, member of such partnership or the beneficial owner of such payment
had such beneficiary, settlor, member or beneficial owner been the Holder of
such Note (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being referred to collectively or individually as
"Colombian Withholding Taxes"). If the Company is required by law to deduct any
Colombian Withholding Taxes from or in respect of any sum payable under this
Note, the sum payable hereunder shall be increased by the amount


<PAGE>   8

necessary so that after making all required deductions the Holder will receive
an amount equal to the sum it would have received had no such deductions been
made.

                  From and after March 15, 2001, interest on this Note will
accrue from the most recent date to which interest has been paid [on this Note
or the Note surrendered in Exchange herefor]* or, if no interest has been paid,
from March 15, 2001; provided that, if there is no existing default in the
payment of interest and if this Note is authenticated between a Regular Record
Date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such Interest Payment Date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

                  The Company shall pay interest on overdue principal and
premium, if any, and interest on overdue installments of interest, to the extent
lawful, at a rate per annum equal to the rate of interest applicable to the
Notes.

2.  Method of Payment.

                  The Company will pay interest (except Defaulted Interest) on
the principal amount of the Notes on each March 15 and September 15 to the
persons who are Holders (as reflected in the Security Register at the close of
business on the March 1 and September 1 immediately preceding the Interest
Payment Date), in each case, even if the Note is cancelled on registration of
transfer or registration of exchange after such record date; provided that, with
respect to the payment of principal, the Company will make payment to the Holder
that surrenders this Note to any Paying Agent on or after March 15, 2004.

                  The Company will pay principal, premium, if any, and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. However, the Company may pay principal,
premium, if any, and interest by its check payable in such money. The Company
may mail an interest check to a Holder's registered address (as reflected in the
Security Register). The Company may also make any payment of monies required to
be deposited with the Trustee on account of principal of, or premium, if any, or
interest on, this Note by wire transfer in immediately available funds to an
account designated by the Trustee on or before the date such monies are to be
paid to the Holder. If a payment date is a date other than a Business Day,
payment may be made on the next succeeding day that is a Business Day and no
interest shall accrue for the intervening period.

3.   Priority of Concession Proceeds.

                  Prior to the Pledge Effective Date (as defined in the
Indenture), the indebtedness evidenced by the Notes is, to the extent and in the
manner provided in the Indenture, subject in right of payment to the prior
payment in full of indebtedness under the Bank Facility to the extent of the
Concession Proceeds (in each case, as defined in the Indenture). Each Holder of
this Note, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate in order to effectuate such provisions
and (c) appoints the Trustee his attorney-in-fact for such purpose.

4.  Paying Agent and Registrar.

                  Initially, the Trustee will act as authenticating agent,
Paying Agent and Registrar. The Company may change any authenticating agent,
Paying Agent or Registrar upon written notice thereto. The Company, any
Subsidiary or any Affiliate of any of them may act as Paying Agent, Registrar or
co-registrar.

5.  Indenture; Limitations.

                  The Company issued the Notes under an Indenture dated as of
June 1, 1996 (the "Indenture"), between the Company and The Bank of New York, as
trustee (the "Trustee"). Capitalized terms herein are used as defined in the
Indenture unless otherwise indicated. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the Trust Indenture Act for a statement of all
such terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this Note and the terms of the Indenture, the
terms of the Indenture shall control.

                  The Notes are general unsecured obligations of the Company.
The Indenture limits the aggregate principal amount of the Notes to
US$190,745,000.

6.  Redemption.

                  Mandatory Redemption. The Company will redeem 50% of the
original aggregate principal amount at maturity of the Notes on March 15, 2003
at 100% of the principal amount thereof, together with accrued and unpaid
interest to the redemption date, on a pro rata basis from the Holders of the
Notes at the close of business on March 1, 2003.

thereof, and (iii) on or after March 15, 2000, at the following Redemption

relevant Regular Record Date to receive interest due on the applicable Interest
Payment Date), if redeemed during the 12-month period beginning March 15 of each
of the years set forth below:

</TABLE>

                  Optional Redemption upon a Public Equity Offering. On or prior
to March 15, 1999, the Company may redeem up to 33% of the original aggregate
principal amount at maturity of the Notes, within 45 days after a Public Equity
Offering, using the net proceeds of such sale, at a redemption price of 114% of
the Accreted Value of Notes so redeemed; provided that no less than 67% of the
original aggregate principal amount at maturity of the Notes remains
outstanding.

                  Optional Redemption for Changes in Colombian Withholding Tax.
The Notes may be redeemed at the election of the Company if, as a result of any
change in, or amendment to, the laws (including any regulations promulgated
thereunder) of Colombia (or any political subdivision or taxing authority
thereof or therein), or any change in, or amendment to, any official position
regarding the application or interpretation of such laws or regulations, which
change or amendment is announced or becomes effective on or after the Issue
Date, the Company has become or would be obligated to pay, on any date on which
any amount would be payable under or with respect to the Securities, any
Additional Amounts as a result of certain changes affecting Colombian
Withholding Tax, then the Company may, at its option, redeem the Notes, as a
whole but not in part, at any time at a redemption price equal to 100% of the
Accreted Value thereof, together with accrued and unpaid interest thereon, if
any, to the redemption date.

                  Notice of a redemption will be mailed at least 30 days but not
more than 60 days before the Redemption Date to each Holder of Notes to be
redeemed at such Holder's last address as it appears in the Security Register.
Notes in original denominations larger than US$1,000 principal amount at
maturity may be redeemed in part in integral multiples of US$1,000 principal
amount at maturity. On and after the Redemption Date, interest ceases to accrue
on Notes or portions of Notes called for redemption, unless the Company defaults
in the payment of the Redemption Price.

7.  Repurchase upon a Change of Control.

                  Upon the occurrence of a Change in Control, each Holder shall
have the right to require that the Company repurchase such Holder's Notes, in
whole or in part, in integral multiples of $1,000 principal amount at final
Maturity, at a purchase price in cash in an amount equal to 101% of the Accreted
Value thereof, plus accrued interest (if any) to the date of purchase (the
"Change of Control Purchase Price").

                  A notice of each Change in Control will be mailed within 15
days after such Change of Control occurs to each Holder at his last address as
it appears in the Security Register. On and after the Change of Control Payment
Date, interest ceases to accrue on Notes or portions of Notes surrendered for
purchase by the Company, unless the Company defaults in the payment of the
Change of Control Purchase Price.

8.  Denominations; Transfer; Exchange.

                  The Notes are in registered form without coupons, in
denominations of $1,000 principal amount at maturity and multiples of $1,000 in
excess thereof. A Holder may register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not register the transfer or exchange of any Notes selected for redemption
(except the unredeemed portion of any Note being redeemed in part). Also, it
need not register the transfer or exchange of any Notes for a period of 15 days
before a selection of Notes to be redeemed is made.

9.  Persons Deemed Owners.

                  A Holder may be treated as the owner of a Note for all
purposes.

10.  Unclaimed Money.

                  If money for the payment of principal, premium, if any, or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company at its request. After that, Holders entitled
to the money must look to the Company for payment, unless an abandoned property
law designates another Person, and all liability of the Trustee and such Paying
Agent with respect to such money shall cease.

11.  Amendment; Supplement; Waiver.


<PAGE>   12

                  Subject to certain exceptions, the Indenture or the Notes may
be amended or supplemented with the consent of the Holders of at least a
majority in aggregate principal amount at final Maturity of the Notes then
outstanding, and any existing default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount at final Maturity of the Notes then outstanding. Without notice to or the
consent of any Holder, the parties thereto may amend or supplement the Indenture
or the Notes to, among other things, cure any ambiguity, or inconsistency
provided such change does not materially adversely affect the rights of any
Holder.

12.  Restrictive Covenants.

in other businesses, restrict payments from Restricted Subsidiaries or merge,
consolidate or transfer substantially all of its assets. At the end of each
fiscal year, the Company must report to the Trustee on compliance with such
limitations.

13.  Successor Persons.

                  When a successor person or other entity assumes all the
obligations of its predecessor under the Notes and the Indenture, the
predecessor person will be released from those obligations.

to or for the benefit of such Person to secure such Indebtedness pursuant to the
terms of any agreement or instrument evidencing any such Indebtedness of the
Company or any Subsidiary or in accordance with applicable law subsequent to a
default in the performance, or breach, of any covenant or warranty of the
Company contained in any agreement or instrument evidencing any such
Indebtedness; (g) one or more final judgments or orders shall be rendered

Registration Statement to be declared effective by the SEC within 150 days after
the Closing Date, (C) to cause such Registration Statement to remain effective
until the closing of the Exchange Offer and (D) to consummate the Exchange Offer
within 180 days following the Closing Date. The Exchange Securities will be
issued under the Indenture. As soon as practicable, but in no event later than
one week, after the effectiveness of the Exchange Offer Registration Statement,
the Company shall commence the Exchange Offer, it being the objective of such
Exchange Offer to enable each Holder (other than Participating Broker-Dealers
(as defined in Section 3(f)) eligible and electing to exchange Registrable
Securities for Exchange Securities (assuming that such Holder is not an
affiliate of the Company within the meaning of Rule 405 under the 1933 Act,
acquires the Exchange Securities in the ordinary course of such Holder's
business and has no arrangements or understandings with any Person to
participate in the Exchange Offer for the purpose of distributing the Exchange
Securities) to trade such Exchange Securities from and after their receipt
without any limitations or restrictions under the 1933 Act and without material
restrictions under the securities laws of a substantial proportion of the
several states of the United States.

         In connection with the Exchange Offer, the Company shall:

         (i) mail to each Holder a copy of the Prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;

         (ii) keep the Exchange Offer open for not less than 30 days after the
     date notice thereof is mailed to the Holders (or longer if required by
     applicable law);

         (iii) use the services of the Depositary for the Exchange Offer;

         (iv) permit Holders to withdraw tendered Registrable Securities at any
     time prior to 5:00 P.M. New York City time, on the last business day on
     which the Exchange Offer shall remain open, by sending to the institution
     specified in the notice, a telegram, telex,
<PAGE>   6
                                        5

     facsimile transmission or letter setting forth the name of such Holder, the
     principal amount of Registrable Securities delivered for exchange, and a
     statement that such Holder is withdrawing his election to have such
     Securities exchanged; and

                  (v) otherwise comply in all respects with all applicable laws
         relating to the Exchange Offer.

                  As soon as practicable after the close of the Exchange Offer,
         the Company shall:

                  (i) accept for exchange Registrable Securities duly tendered
         and not validly withdrawn pursuant to the Exchange Offer in accordance
         with the terms of the Exchange Offer Registration Statement and the
         letter of transmittal which is an exhibit thereto;

                  (ii) deliver, or cause to be delivered, to the Trustee for
         cancellation all Registrable Securities so accepted for exchange by the
         Company; and

                  (iii) cause the Trustee promptly to authenticate and deliver
         Exchange Securities to each Holder of Registrable Securities equal in
         Accreted Value (as defined in the Indenture) to the Accreted Value of
         the Registrable Securities of such Holder so accepted for exchange.

                  Interest on each Exchange Security will accrue from the last
date on which interest was paid on the Registrable Securities surrendered in
exchange therefor or, if no interest has been paid on the Registrable
Securities, from the date on which interest first began to accrue on the
Registrable Securities. The Exchange Offer shall not be subject to any
conditions, other than (i) that the Exchange Offer, or the making of any
exchange by a Holder, does not violate applicable law or any applicable
interpretation of the Staff of the SEC (ii) the due tendering of Registrable
Securities in accordance with the Exchange Offer, (iii) that no action or
proceeding shall have been instituted or threatened in any court or by or before
any governmental agency with respect to the Exchange Offer which, in the
Company's judgment, would reasonably be expected to impair the ability of the
Company to proceed with the Exchange Offer, (iv) that there shall not have been
adopted or enacted any law, statute, rule or regulation which, in the Company's
judgment, would reasonably be expected to impair the ability of the Company to
proceed with the Exchange Offer, (v) that there shall not have been declared by
U.S. federal, New York State or Colombian authorities a banking moratorium
which, in the Company's judgment, would reasonably be expected to impair the
ability of the Company to proceed with the Exchange Offer, (vi) that trading
generally on either the American Stock Exchange, the New York Stock Exchange or
the over-the-counter market shall not have been suspended by order of the SEC or
any other governmental authority, which, in the Company's judgment, would
reasonably be expected to impair the ability of the Company to proceed with the
Exchange Offer and (vii) that each Holder of Registrable Securities (other than
Participating Broker-Dealers) who wishes to exchange such Registrable Securities
for Exchange Securities in the Exchange Offer shall have represented that (A) it
is not an affiliate of the Company, (B) any Exchange Securities to be received
by it will be acquired in the ordinary course of business and (C) at the time of
the commencement of the Exchange Offer it has no arrangement with any Person to
participate in the distribution (within the meaning of the Securities Act) of
the Exchange Securities and shall have made such other representations as may be
reasonably necessary under applicable SEC rules, regulations or interpretations
to render the use of Form F-4 or another appropriate form under the 1933 Act
available. To the extent permitted by law, the Company shall inform the Initial
Purchasers
<PAGE>   7
                                        6

of the names and addresses of the Holders to whom the Exchange Offer is made,
and the Initial Purchasers shall have the right to contact such Holders and
otherwise facilitate the tender of Registrable Securities in the Exchange Offer.

         (b) Shelf Registration. (i) If, because of any change in law or
applicable interpretations thereof by the Staff of the SEC, the Company is not
permitted to effect the Exchange Offer as contemplated by Section 2(a) hereof,
or (ii) if for any other reason the Exchange Offer is not consummated within 180
days after the Closing Date, or (iii) if any Holder (other than an Initial
Purchaser) is not eligible to participate in the Exchange Offer or (iv) upon the
request of any Initial Purchaser (with respect to any Registrable Securities
which it acquired directly from the Company) following the consummation of the
Exchange Offer if such Initial Purchaser shall hold Registrable Securities which
it acquired directly from the Company and if such Initial Purchaser is not
permitted, in the opinion of counsel to such Initial Purchaser, pursuant to
applicable law or applicable interpretation of the Staff of the SEC to
participate in the Exchange Offer, the Company shall, at its cost,

         (A) as promptly as practicable, file with the SEC a Shelf Registration
     Statement relating to the offer and sale of the Registrable Securities by
     the Holders from time to time in accordance with the methods of
     distribution elected by the Majority Holders of such Registrable Securities
     and set forth in such Shelf Registration Statement, and use its best
     efforts to cause such Shelf Registration Statement to be declared effective
     by the SEC within 210 days after the Closing Date. In the event that the
     Company is required to file a Shelf Registration Statement upon the request
     of any Holder (other than an Initial Purchaser) not eligible to participate
     in the Exchange Offer pursuant to clause (iii) above or upon the request of
     any Initial Purchaser pursuant to clause (iv) above, the Company shall file
     and have declared effective by the SEC both an Exchange Offer Registration
     Statement pursuant to Section 2(a) with respect to all Registrable
     Securities and a Shelf Registration Statement (which may be a combined
     Registration Statement with the Exchange Offer Registration Statement) with
     respect to offers and sales of Registrable Securities held by such Holder
     or such Initial Purchaser after completion of the Exchange Offer.

         (B) use its best efforts to keep the Shelf Registration Statement
     continuously effective in order to permit the Prospectus forming part
     thereof to be usable by Holders for a period of three years from the date
     the Shelf Registration Statement is declared effective by the SEC (or one
     year from the date the Shelf Registration Statement is declared effective
     if such Shelf Registration Statement is filed upon the request of any
     Initial Purchaser pursuant to clause (iv) above) or such shorter period
     which will terminate when all of the Registrable Securities covered by the
     Shelf Registration Statement have been sold pursuant to the Shelf
     Registration Statement.

         (C) notwithstanding any other provisions hereof, use its best efforts
     to ensure that (i) any Shelf Registration Statement and any amendment
     thereto and any Prospectus forming part thereof and any supplement thereto
     comply in all material respects with the 1933 Act and the rules and
     regulations thereunder, (ii) any Shelf Registration Statement and any
     amendment thereto do not, upon effectiveness, contain an untrue statement
     of a material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein
<PAGE>   8
                                        7

     not misleading and (iii) any Prospectus forming part of any Shelf
     Registration Statement, and any supplement to such Prospectus (as amended
     or supplemented from time to time), do not include an untrue statement of a
     material fact or omit to state a material fact necessary in order to make
     the statements, in light of the circumstances under which they were made,
     not misleading.

                  The Company further agrees, if necessary, to supplement or
amend the Shelf Registration Statement if reasonably requested by the Majority
Holders with respect to information relating to the Holders and otherwise as
required by Section 3(b) below, to use all reasonable efforts to cause any such
amendment to become effective and such Shelf Registration to become usable as
soon as thereafter practicable and to furnish to the Holders of Registrable
Securities copies of any such supplement or amendment promptly after its being
used or filed with the SEC.

                  (c) Expenses. The Company shall pay all Registration Expenses
in connection with the registration pursuant to Section 2(a) or 2(b) and, in the
case of any Shelf Registration Statement, will reimburse the Holders or Initial
Purchasers for the reasonable fees and disbursements of one United States firm
or counsel and one Colombian firm or counsel designated in writing by the
Majority Holders to act as counsel for the Holders of the Registrable Securities
in connection therewith. Each Holder shall pay all expenses of its counsel other
than as set forth in the preceding sentence, underwriting discounts and
commissions and transfer taxes, if any, relating to the sale or disposition of
such Holder's Registrable Securities pursuant to the Shelf Registration
Statement.

                  (d) Effective Registration Statement. (i) The Company will be
deemed not to have used its best efforts to cause the Exchange Offer
Registration Statement or the Shelf Registration Statement, as the case may be,
to become, or to remain, effective during the requisite period if it voluntarily
takes any action that would result in any such Registration Statement not being
declared effective or in the Holders of Registrable Securities covered thereby
not being able to exchange or offer and sell such Registrable Securities during
that period unless (A) such action is required by applicable law or (B) such
action is taken by the Company in good faith and for valid business reasons (not
including avoidance of the Company's obligations hereunder), including the
acquisition or divestiture of assets, so long as the Company promptly complies
with the requirements of Section 3(k) hereof, if applicable.

                  (ii) The Company may suspend the availability of the Shelf
Registration Statement and the use of the Prospectus for a period not to exceed
30 days in any three month period or four periods not to exceed an aggregate of
60 days in any 12 month period if such suspension is effected in good faith and
for valid business reasons (not including avoidance of the Company's obligations
hereunder), including the acquisition or divestiture of assets, the filing of
public reports with the SEC and during the pendency of material corporate
developments, so long as the Company promptly complies with the requirements of
Section 3(k) hereof (including compliance with the obligation to prepare a
supplement or amendment to a Registration Statement and related Prospectus if
necessary) promptly after the termination of such suspension.

                  (iii) An Exchange Offer Registration Statement pursuant to
Section 2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b)
hereof will not be deemed to have become effective unless it has been declared
effective by the SEC; provided, however, that if, after it has
<PAGE>   9
                                        8

been declared effective, the offering of Registrable Securities pursuant to a
Registration Statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
Registration Statement will be deemed not to have been effective during the
period of such interference, until the offering of Registrable Securities
pursuant to such Registration Statement may legally resume.

                  (e) Increase in Interest Rate. In the event that (i) the
Exchange Offer Registration Statement is not filed with the SEC on or prior to
the 60th calendar day after the Closing Date, (ii) the Exchange Offer
Registration Statement is not declared effective on or prior to the 150th
calendar day after the Closing Date, (iii) the Exchange Offer is not consummated
on or prior to the 180th calendar day after the Closing Date or a Shelf
Registration Statement with respect to the Registrable Securities is not
declared effective on or prior to the 210th day after the Closing Date or (iv)
the Exchange Offer Registration Statement is declared effective but thereafter
ceases to be effective or usable except pursuant to Section 2(d)(ii), the
Company shall pay additional interest on the Securities (in addition to the
accrual of original issue discount pursuant to the terms of the Securities and
in addition to the interest otherwise due thereon) with respect to the first
90-day period from and including the first day immediately following such 60-day
period in the case of (i) above, such 150-day period in the case of (ii) above,
such 180-day or 210-day period in the case of (iii) above, or such event
described in (iv) above, at a rate of one-half of one percent (0.5%) per annum
of the Accreted Value (as defined in the Indenture), payable in cash on each
Semiannual Accrual Date (as defined in the Indenture) (or, after the fifth
anniversary of the Closing Date, on each interest payment date), such interest
rate to increase by an additional one-half of one percent (0.5%) for each
subsequent 90-day period, up to a maximum increase of one and one-half percent
(1.5%) per annum of the Accreted Value. Upon (x) the filing of the Exchange
Offer Registration Statement after the 60-day period described in clause (i)
above, (y) the effectiveness of the Exchange Offer Registration Statement after
the 150-day period described in clause (ii) above or the period during which it
ceases to be effective or usable as described in clause (iv) above or (z) the
consummation of the Exchange Offer after the 180-day period or the effectiveness
of a Shelf Registration Statement after the 210-day period, as the case may be,
described in clause (iii) above, and provided that none of the conditions set
forth in clauses (i), (ii), (iii) and (iv) above continues to exist, such
additional interest shall cease to accrue on the Securities from the date of
such filing, effectiveness or consummation, as the case may be.

                  (f) Specific Enforcement. Without limiting the remedies
available to the Initial Purchasers and the Holders, the Company acknowledges
that any failure by the Company to comply with its obligations under Section 
2(a) and Section 2(b) hereof may result in material irreparable injury to the
Initial Purchasers or the Holders for which there is no adequate remedy at law,
that it will not be possible to measure damages for such injuries precisely and
that, in the event of any such failure, the Initial Purchasers or any Holder may
obtain such relief as may be required to specifically enforce the Company's
obligations under Section 2(a) and Section 2(b) hereof.

                  3. Registration Procedures. In connection with the obligations
of the Company with respect to the Registration Statements pursuant to Sections 
2(a) and 2(b) hereof, the Company shall:

                  (a) prepare and file with the SEC a Registration Statement,
     within the time period specified in Section 2, on the appropriate form
     under the 1933 Act, which form (i) shall be selected by the Company, (ii)
     shall, in the case of a Shelf Registration, be available for the sale of
     the Registrable Securities by the selling Holders thereof and (iii) shall
     comply as to form in all material respects with the requirements of the
     applicable form and include or incorporate by reference all financial
     statements required by the SEC to be filed therewith, and use its best
     efforts to cause such Registration Statement to become effective and remain
     effective in accordance with Section 2 hereof;

                  (b) prepare and file with the SEC such amendments and
     post-effective amendments to each Registration Statement as may be
     necessary under applicable law to keep such Registration Statement
     effective for the applicable period; cause each Prospectus to be

     to be filed pursuant to Rule 424 under the 1933 Act; and comply with the
     provisions of the 1933 Act with respect to the disposition of all
     Securities covered by each Registration Statement during the applicable
     period in accordance with the intended method or methods of distribution by

                  (c) in the case of a Shelf Registration, (i) notify each
     Holder of Registrable Securities, at least five days prior to filing, that
     a Shelf Registration Statement with respect to the Registrable Securities
     is being filed and advising such Holders that the distribution of
     Registrable Securities will be made in accordance with the method elected
     by the Majority Holders; and (ii) furnish to each Holder of Registrable
     Securities, to counsel for the Initial Purchasers, to counsel for the

     Securities, if any, without charge, as many copies of each Prospectus,
     including each preliminary Prospectus, and any amendment or supplement
     thereto and such other documents as such Holder or underwriter may
     reasonably request, including financial statements and schedules and, if
     the Holder so requests, all exhibits (including those incorporated by
     reference) in order to facilitate the public sale or other disposition of
     the Registrable Securities; and (iii) subject to the last paragraph of this
     Section 3, hereby consent to the use of the Prospectus or any amendment or
     supplement thereto by each of the selling Holders of Registrable Securities
     in connection with the offering and sale of the Registrable Securities
     covered by the Prospectus or any amendment or supplement thereto;

                  (d) use its best efforts to register or qualify the
     Registrable Securities under all applicable state securities or "blue sky"
     laws of such jurisdictions as any Holder of Registrable Securities covered
     by a Registration Statement and each underwriter of an Underwritten
     Offering of Registrable Securities shall reasonably request by the time the
     applicable Registration Statement is declared effective by the SEC, to
     cooperate with the Holders in connection with any filings required to be
     made with the NASD, and do any and all other acts and things which may be
     reasonably necessary or advisable to enable such Holder to consummate the
     disposition in each such jurisdiction of such Registrable Securities owned
     by such Holder; provided, however, that the Company shall not be required
     to (i) qualify as a foreign corporation or as a dealer in securities in any
     jurisdiction where it would not otherwise be required to qualify but for
     this Section 3(d) or (ii) take any action
<PAGE>   11
                                       10

     which would subject it to general service of process or taxation in any
     such jurisdiction if it is not then so subject;

                  (e) in the case of a Shelf Registration, notify each Holder of
     Registrable Securities and U.S. counsel for the Initial Purchasers promptly
     and, if requested by such Holder or counsel, confirm such advice in writing
     promptly (i) when a Registration Statement has become effective and when
     any post-effective amendments and supplements thereto become effective,
     (ii) of any request by the SEC or any state securities authority for
     post-effective amendments and supplements to a Registration Statement and
     Prospectus or for additional information after the Registration Statement
     has become effective, (iii) of the issuance by the SEC or any state
     securities authority of any stop order suspending the effectiveness of a
     Registration Statement or the initiation of any proceedings for that
     purpose, (iv) if, between the effective date of a Registration Statement
     and the closing of any sale of Registrable Securities covered thereby, the
     representations and warranties of the Company contained in any underwriting
     agreement, securities sales agreement or other similar agreement, if any,
     relating to such offering cease to be true and correct in all material
     respects, (v) of the receipt by the Company of any notification with
     respect to the suspension of the qualification of the Registrable
     Securities for sale in any jurisdiction or the initiation or threatening of
     any proceeding for such purpose, (vi) of the suspension of the availability
     of the Shelf Registration Statement and the use of the Prospectus pursuant
     to Section 2(d)(ii) hereof or of the happening of any event or the
     discovery of any facts during the period a Shelf Registration Statement is
     effective which makes any statement made in such Registration Statement or
     the related Prospectus untrue in any material respect or which requires the
     making of any changes in such Registration Statement or Prospectus in order
     to make the statements therein not misleading and (vii) of any
     determination by the Company that a post-effective amendment to a
     Registration Statement would be appropriate;

                  (f) (A) in the case of the Exchange Offer, (i) include in the
     Exchange Offer Registration Statement a "Plan of Distribution" section
     covering the use of the Prospectus included in the Exchange Offer
     Registration Statement by broker-dealers who have exchanged their
     Registrable Securities for Exchange Securities for the resale of such
     Exchange Securities, (ii) furnish to each broker-dealer who desires to
     participate in the Exchange Offer, without charge, as many copies of each
     Prospectus included in the Exchange Offer Registration Statement, including
     any preliminary prospectus, and any amendment or supplement thereto, as
     such broker-dealer may reasonably request, (iii) include in the Exchange
     Offer Registration Statement a statement that any broker-dealer who holds
     Registrable Securities acquired for its own account as a result of
     market-making activities or other trading activities (a "Participating
     Broker-Dealer"), and who receives Exchange Securities for Registrable
     Securities pursuant to the Exchange Offer, may be a statutory underwriter
     and must deliver a Prospectus meeting the requirements of the 1933 Act in
     connection with any resale of such Exchange Securities, (iv) subject to the
     last paragraph of this Section 3, hereby consent to the use of the
     Prospectus forming part of the Exchange Offer Registration Statement or any

     or any amendment or supplement thereto, and (v) include in the transmittal
     letter or similar documentation to be executed by an exchange offeree in
     order to participate in the Exchange Offer (x) the following provision:
<PAGE>   12
                                       11

                  "If the undersigned is not a broker-dealer, the undersigned
                  represents that it is not engaged in, and does not intend to
                  engage in, a distribution of Exchange Securities. If the
                  undersigned is a broker-dealer that will receive Exchange
                  Securities for its own account in exchange for Registrable
                  Securities, it represents that the Registrable Securities to
                  be exchanged for Exchange Securities were acquired by it as a
                  result of market-making activities or other trading activities
                  and acknowledges that it will deliver a Prospectus meeting the
                  requirements of the 1933 Act in connection with any resale of
                  such Exchange Securities pursuant to the Exchange Offer;
                  however, by so acknowledging and by delivering a prospectus,
                  the undersigned will not be deemed to admit that it is an
                  "underwriter" within the meaning of the 1933 Act";

         and (y) a statement to the effect that by a broker-dealer making the
         acknowledgment described in subclause (x) and by delivering a
         Prospectus in connection with the exchange of registrable Securities,
         the broker-dealer will not be deemed to admit that it is an underwriter
         within the meaning of the 1933 Act; and

                  (B) to the extent any Participating Broker-Dealer participates
         in the Exchange Offer, the Company shall use its best efforts to cause
         to be delivered at the request of an entity representing the
         Participating Broker-Dealers (which entity shall be one of the Initial
         Purchasers, unless they elect not to act as such representative) only
         one, if any, "cold comfort" letter with respect to the Prospectus in
         the form existing on the last date for which exchanges are accepted
         pursuant to the Exchange Offer and with respect to each subsequent
         amendment or supplement, if any, effected during the period specified
         in clause (C) below; and

                  (C) to the extent any Participating Broker-Dealer participates
         in the Exchange Offer, the Company shall use its best efforts to
         maintain the effectiveness of the Exchange Offer Registration Statement
         for a period of 180 days following the closing of the Exchange Offer or
         such shorter period which will terminate when the Participating
         Broker-Dealers have completed all resales subject to applicable
         prospectus-delivery requirements; and

                  (D) the Company shall not be required to amend or supplement
         the Prospectus contained in the Exchange Offer Registration Statement
         as would otherwise be contemplated by Section 3(b) hereof, or take any
         other action as a result of this Section 3(f), for a period exceeding
         180 days after the last date for which exchanges are accepted pursuant
         to the Exchange Offer (as such period may be extended by the Company)
         and Participating Broker-Dealers shall not be authorized by the Company
         to, and shall not, deliver such Prospectus after such period in
         connection with resales contemplated by this Section 3.

                  (g) in the case of an Exchange Offer or a Shelf Registration,
         furnish U.S. counsel for the Initial Purchasers copies of any request
         by the SEC or any state securities authority for amendments or
         supplements to a Registration Statement and Prospectus or for
         additional information;
<PAGE>   13
                                       12

                  (h) make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of a Registration Statement as
         soon as practicable and provide immediate notice to each Holder of the
         withdrawal of any such order;

                  (i) in the case of a Shelf Registration, furnish to each
         Holder of Registrable Securities, without charge, at least one
         conformed copy of each Registration Statement and any post-effective
         amendment thereto (without documents incorporated therein by reference
         or exhibits thereto, unless requested);

                  (j) in the case of a Shelf Registration, cooperate with the
         selling Holders of Registrable Securities to facilitate the timely
         preparation and delivery of certificates representing Registrable
         Securities to be sold and not bearing any restrictive legends
         pertaining to U.S. securities laws; and cause such Registrable
         Securities to be in such denominations (consistent with the provisions
         of the Indenture) and registered in such names as the selling Holders
         or the underwriters, if any, may reasonably request at least two
         business days prior to the closing of any sale of Registrable
         Securities;

                  (k) in the case of a Shelf Registration, upon the occurrence
         of any event or the discovery of any facts, each as contemplated by
         Section 3(e)(vi) hereof, use its best efforts to prepare a supplement
         or post-effective amendment to a Registration Statement or the related
         Prospectus or any document incorporated therein by reference or file
         any other required document so that, as thereafter delivered to the
         purchasers of the Registrable Securities, such Prospectus will not
         contain at the time of such delivery any untrue statement of a material
         fact or omit to state a material fact necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading. The Company agrees to notify each Holder to suspend use of
         the Prospectus as promptly as practicable after the occurrence of such
         an event, and each Holder hereby agrees to suspend use of the
         Prospectus until the Company has amended or supplemented the Prospectus
         to correct such misstatement or omission. At such time as such public
         disclosure is otherwise made or the Company determines that such
         disclosure is not necessary, in each case to correct any misstatement
         of a material fact or to include any omitted material fact, the Company
         agrees promptly to notify each Holder of such determination and to
         furnish each Holder such numbers of copies of the Prospectus, as
         amended or supplemented, as such Holder may reasonably request;

                  (l) obtain a CUSIP number for all Exchange Securities, or
         Registrable Securities, as the case may be, not later than the
         effective date of a Registration Statement, and provide the Trustee
         with printed certificates for the Exchange Securities or the
         Registrable Securities, as the case may be, in a form eligible for
         deposit with the Depositary;

                  (m) (i) cause the Indenture to be qualified under the Trust
         Indenture Act of 1939, as amended (the "TIA"), in connection with the
         registration of the Exchange Securities, or Registrable Securities, as
         the case may be, (ii) cooperate with the Trustee and the Holders to
         effect such changes to the Indenture as may be required for the
         Indenture to be so qualified in accordance with the terms of the TIA
         and (iii) execute, and use its best efforts to cause the Trustee to
         execute, all documents as may be required to effect such changes, and
         all other
<PAGE>   14
                                       13

         forms and documents required to be filed with the SEC to enable the
         Indenture to be so qualified in a timely manner;

                  (n) in the case of a Shelf Registration, enter into agreements
         (including underwriting agreements) and take all other customary and
         appropriate actions (including those reasonably requested by the
         Majority Holders) in order to expedite or facilitate the disposition of
         such Registrable Securities and in such connection whether or not an
         underwriting agreement is entered into and whether or not the
         registration is an underwritten registration:

                           (i) make such representations and warranties to the
                  Holders of such Registrable Securities and the underwriters,
                  if any, in form, substance and scope as are customarily made
                  by issuers to underwriters in similar underwritten offerings
                  as may be reasonably requested by them;

                           (ii) obtain opinions of counsel to the Company and
                  updates thereof (which counsel and opinions (in form, scope
                  and substance) shall be reasonably satisfactory to the
                  managing underwriters, if any, and the Holders of a majority
                  in principal amount of the Registrable Securities being sold)
                  addressed to each selling Holder and the underwriters, if any,
                  covering the matters customarily covered in opinions requested
                  in sales of securities or underwritten offerings and such
                  other matters as may be reasonably requested by such Holders
                  and underwriters;

                           (iii) obtain "cold comfort" letters and updates
                  thereof from the Company's independent certified public
                  accountants addressed to the underwriters, if any, and will
                  use reasonable best efforts to have such letter addressed to
                  the selling Holders of Registrable Securities, such letters to
                  be in customary form and covering matters of the type
                  customarily covered in "cold comfort" letters to underwriters
                  in connection with similar underwritten offerings;

                           (iv) enter into a securities sales agreement with the
                  Holders and an agent of the Holders providing for, among other
                  things, the appointment of such agent for the selling Holders
                  for the purpose of soliciting purchases of Registrable
                  Securities, which agreement shall be in form, substance and
                  scope customary for similar offerings;

                           (v) if an underwriting agreement is entered into in
                  the case of an Underwritten Offering, cause the same to set
                  forth indemnification provisions and procedures substantially
                  equivalent to the indemnification provisions and procedures
                  set forth in Section 5 hereof with respect to the underwriters
                  and all other parties to be indemnified pursuant to said
                  Section ; and

                           (vi) deliver such documents and certificates as may
                  be reasonably requested and as are customarily delivered in
                  similar offerings.
<PAGE>   15
                                       14

                  The above shall be done at (i) the effectiveness of such
         Registration Statement (and, if appropriate, each post-effective
         amendment thereto) and (ii) each closing under any underwriting or
         similar agreement as and to the extent required thereunder. In the case
         of any Underwritten Offering, the Company shall provide written notice
         to the Holders of all Registrable Securities of such Underwritten
         Offering at least 30 days prior to the filing of a prospectus
         supplement for such Underwritten Offering. Such notice shall (x) offer
         each such Holder the right to participate in such Underwritten
         Offering, (y) specify a date, which shall be no earlier than 10 days
         following the date of such notice, by which such Holder must inform the
         Company of its intent to participate in such Underwritten Offering and
         (z) include the instructions such Holder must follow in order to
         participate in such Underwritten Offering;

                  (o) in the case of a Shelf Registration, make available for
         inspection by representatives of the Holders of the Registrable
         Securities and any underwriters participating in any disposition
         pursuant to a Shelf Registration Statement and any U.S. counsel or
         accountant retained by such Holders or underwriters, all financial and
         other records, pertinent corporate documents and properties of the
         Company reasonably requested by any such persons, and cause the
         respective officers, directors, employees, and any other agents of the
         Company to supply all information reasonably requested by any such
         representative, underwriter, special counsel or accountant in
         connection with a Registration Statement; provided that any such
         records, documents, properties and such information that is designated
         in writing by the Company, in good faith, as confidential at the time
         of delivery of such records, documents, properties or information shall
         be kept confidential by any such representative, underwriter, special
         counsel or accountant and shall be used only in connection with such
         Registration Statement, unless disclosure thereof is made in connection
         with a court proceeding or required by law, or such information has
         become available (not in violation of this agreement) to the public
         generally or through a third party without an accompanying obligation
         of confidentiality, and the Company shall be entitled to request that
         such representative, underwriter, special counsel or accountant sign a
         confidentiality agreement to the foregoing effect;

                  (p) (i) a reasonable time prior to the filing of any Exchange
         Offer Registration Statement, any Prospectus forming a part thereof,
         any amendment to an Exchange Offer Registration Statement or amendment
         or supplement to a Prospectus, provide copies of such document to the
         Initial Purchasers, and make such changes in any such document prior to
         the filing thereof as any of the Initial Purchasers or their U.S.
         counsel may reasonably request; (ii) in the case of a Shelf
         Registration, a reasonable time prior to filing any Shelf Registration
         Statement, any Prospectus forming a part thereof, any amendment to such
         Shelf Registration Statement or amendment or supplement to such
         Prospectus, provide copies of such document to the Holders of
         Registrable Securities, to the Initial Purchasers, to U.S. counsel on

         changes in any such document prior to the filing thereof as the Holders
         of Registrable Securities, the Initial Purchasers on behalf of such

         (iii) cause the representatives of the Company to be available for
         discussion of such document as shall be reasonably requested by the
         Holders of Registrable Securities, the Initial Purchasers on behalf of
         such Holders or any

                                       15

         underwriter and shall not at any time make any filing of any such
         document of which such Holders, the Initial Purchasers on behalf of
         such Holders, their U.S. counsel or any underwriter shall not have
         previously been advised and furnished a copy or to which such Holders,
         the Initial Purchasers on behalf of such Holders, their counsel or any
         underwriter shall reasonably object;

                  (q) in the case of a Shelf Registration, use its best efforts
         to cause all Registrable Securities to be listed on any securities
         exchange on which similar debt securities issued by the Company are
         then listed if requested by the Majority Holders or by the underwriter
         or underwriters of an Underwritten Offering of Registrable Securities,
         if any;

                  (r) in the case of a Shelf Registration, use its best efforts
         to cause the Registrable Securities to be rated with the appropriate
         rating agencies, if so requested by the Majority Holders or by the
         underwriter or underwriters of an Underwritten Offering of Registrable
         Securities, if any, unless the Registrable Securities are already so
         rated;

                  (s) otherwise use its best efforts to comply with all
         applicable rules and regulations of the SEC and make available to its
         security holders, as soon as reasonably practicable, an earnings
         statement covering at least 12 months which shall satisfy the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder;
         and

                  (t) cooperate and assist in any filings required to be made
         with the NASD and in the performance of any due diligence investigation
         by any underwriter and its U.S. counsel.

                  In the case of a Shelf Registration Statement, the Company may
(as a condition to such Holder's participation in the Shelf Registration)
require each Holder of Registrable Securities to furnish to the Company such
information regarding such Holder and the proposed distribution by such Holder
of such Registrable Securities as the Company may from time to time reasonably
request in writing.

                  In the case of a Shelf Registration Statement, each Holder
agrees that, upon receipt of any notice from the Company of the happening of any
event or the discovery of any facts, each of the kind described in Section 
3(e)(ii)-(vi) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(k) hereof, and, if so directed by the Company, such Holder will
deliver to the Company (at its expense) all copies in its possession, other than
permanent file copies then in such Holder's possession, of the Prospectus
covering such Registrable Securities current at the time of receipt of such
notice. If the Company shall give any such notice to suspend the disposition of
Registrable Securities pursuant to a Shelf Registration Statement as a result of
the happening of any event or the discovery of any facts, each of the kind
described in Section 3(e)(vi) hereof, the Company shall be deemed to have used
its best efforts to keep the Shelf Registration Statement effective during such
period of suspension provided that the Company shall use its best efforts to
file and have declared effective (if an amendment) as soon as practicable an
amendment or supplement to the Shelf Registration Statement and shall extend the
period during which the Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days during the period from and
including the date of the giving of such
<PAGE>   17
                                       16

notice to and including the date when the Holders shall have received copies of
the supplemented or amended Prospectus necessary to resume such dispositions.

                  4. Underwritten Registrations. If any of the Registrable
Securities covered by any Shelf Registration are to be sold in an Underwritten
Offering, the investment banker or investment bankers and manager or managers
that will manage the offering will be selected by the Majority Holders of such
Registrable Securities included in such offering and shall be reasonably
acceptable to the Company.

                  No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

                  5. Indemnification and Contribution. (a) The Company shall
indemnify and hold harmless each Initial Purchaser, each Holder, including
Participating Broker-Dealers, each underwriter who participates in an offering
of Registrable Securities, their respective affiliates, and the respective
directors, officers, employees, agents and each Person, if any, who controls any
of such parties within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact contained in any
         Registration Statement (or any amendment thereto) pursuant to which
         Exchange Securities or Registrable Securities were registered under the
         1933 Act, including all documents incorporated therein by reference, or
         the omission or alleged omission therefrom of a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact contained in any Prospectus (or any
         amendment or supplement thereto) or the omission or alleged omission
         therefrom of a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading;

                  (ii) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission; provided
         that (subject to Section 5(d) below) any such settlement is effected
         with the written consent of the Company; and

                  (iii) against any and all expense whatsoever, as incurred
         (including the fees and disbursements of United States and Colombian
         counsel chosen by any indemnified party), reasonably incurred in
         investigating, preparing or defending against any litigation, or
         investigation or proceeding by any governmental agency or body,
         commenced or threatened in
<PAGE>   18
                                       17

         connection with, or any claim whatsoever based upon, any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, to the extent that any such expense is not paid under
         subparagraph (i) or (ii) of this Section 5(a);

provided, however, that this indemnity does not apply to any loss, liability,
claim, damage or expense to the extent (A) arising out of an untrue statement or
omission or alleged untrue statement or omission (i) made in or omitted from a
preliminary Prospectus or registration statement and corrected or cured in a
subsequent Prospectus or registration statement or any amendment or supplement
thereto, (ii) made in reliance upon and in conformity with information furnished
to the Company by the Initial Purchasers, any Holder, including Participating
Broker-Dealers, or any underwriter expressly for use in the Registration
Statement (or any amendment thereto) or the Prospectus (or any amendment or
supplement thereto), or (B) resulting from the use of the Prospectus during a
period when the use of the Prospectus has been suspended in accordance with
Section 2(d)(ii) or Section 3(e)(vi) hereof, provided, in each case, that
Holders received prior notice of such suspension;

                  (b) In the case of a Shelf Registration, each Holder agrees,
severally and not jointly, to indemnify and hold harmless the Company, the
Initial Purchasers, each underwriter who participates in an offering of
Registrable Securities and the other selling Holders and each of their
respective directors and officers (including each officer of the Company who
signed the Registration Statement) and each Person, if any, who controls the
Company, the Initial Purchasers, any underwriter or any other selling Holder
within the meaning of Section 15 of the 1933 Act, against any and all loss,
liability, claim, damage and expense described in the indemnity contained in
Section 5(a) hereof, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto) or the Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with information
furnished to the Company by such Holder, as the case may be, expressly for use
in the Registration Statement (or any amendment thereto), or the Prospectus (or
any amendment or supplement thereto);

                  (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. An indemnifying
party may participate at its own expense in the defense of any such action and
will be entitled, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, also be counsel to the indemnifying party),
and after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation; provided, however,
that counsel to the indemnifying party shall not (except with the consent of the
indemnified party) also be counsel to the indemnified party. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel, in addition to any Colombian counsel, for all indemnified parties in
connection with any one action or separate but similar or
<PAGE>   19
                                       18

related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 5 hereof (whether or not the indemnified parties
are actual or potential parties thereof), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

                  (d) If at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel for which they are entitled to indemnification hereunder, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 5(a)(ii) hereof effected without its written
consent if (i) such settlement is entered into more than 45 days after receipt
by such indemnifying party of the aforesaid request, (ii) such indemnifying
party shall have received notice of the terms of such settlement at least 30
days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party for such fees and
expenses of counsel in accordance with such request prior to the date of such
settlement.

                  (e) If the indemnification provided for in any of the
indemnity provisions set forth in this Section 5 is for any reason unavailable
to or insufficient to hold harmless an indemnified party in respect of any
losses, liabilities, claims, damages or expenses referred to therein, then each
indemnifying party shall contribute to the aggregate amount of such losses,
liabilities, claims, damages and expenses incurred by such indemnified party, as
incurred, (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand, the Initial Purchasers on
another hand, and the Holders on another hand, from the offering of the Exchange
Securities or Registrable Securities included in such offering or (ii) if the
allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company on the one
hand, the Initial Purchasers on another hand, and the Holders on another hand,
in connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations. The relative fault of the Company on the one hand, the
Initial Purchasers on another hand, and the Holders on another hand shall be
determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company, the
Initial Purchasers or the Holders and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company, the Initial Purchasers and the Holders of the Registrable
Securities agree that it would not be just and equitable if contribution
pursuant to this Section 5 were determined by pro rata allocation (even if the
Initial Purchasers were treated as one entity, and the Holders were treated as
one entity, for such purpose) or by another method of allocation which does not
take account of the equitable considerations referred to above in Section 5. The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 5 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
<PAGE>   20
                                       19

party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by an governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1993 Act) shall be
entitled to contribution from any Person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 5, each Person, if any, who
controls an Initial Purchaser or Holder within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as such Initial Purchaser or Holder, and each director of the
Company, each officer of the Company who signed the Registration Statement, and
each Person, if any, who controls the Company within the meaning of Section 15
of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Company. The parties hereto agree that any underwriting
discount or commission or reimbursement of fees paid to any Initial Purchaser
pursuant to the Purchase Agreement shall not be deemed to be a benefit received
by any Initial Purchaser in connection with the offering of the Exchange
Securities or Registrable Securities included in such offering.

                  6. Miscellaneous. (a) Rule 144 and Rule 144A. For so long as
the Company is subject to the reporting requirements of Section 13 or 15 of the
1934 Act, the Company covenants that it will file or furnish the reports
required to be filed or furnished by it under the 1933 Act and Section 13(a) or
15(d) of the 1934 Act and the rules and regulations adopted by the SEC
thereunder, that if it ceases to be so required to file or furnish such reports,
it will upon the request of any Holder of Registrable Securities (i) make
publicly available such information as is necessary to permit sales pursuant to
Rule 144 under the 1933 Act, (ii) deliver such information to a prospective
purchaser as is necessary to permit sales pursuant to Rule 144A under the 1933
Act and it will take such further action as any Holder of Registrable Securities
may reasonably request, and (iii) take such further action that is reasonable in
the circumstances, in each case, to the extent required from time to time to
enable such Holder to sell its Registrable Securities without registration under
the 1933 Act within the limitation of the exemptions provided by (x) Rule 144
under the 1933 Act, as such Rule may be amended from time to time, (y) Rule 144A
under the 1993 Act, as such Rule may be amended from time to time, or (z) any
similar rules or regulations hereafter adopted by the SEC.

                  (b) No Inconsistent Agreements. The Company has not entered
into and the Company on or after the date of this Agreement will not enter into
any agreement which is inconsistent with the rights granted to the Holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Company's other issued and outstanding securities under any such agreements.

                  (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or departure; provided, however, that no amendment, modification,
supplement or waiver or consent to any departure from the provisions of Section 
5 hereof shall be effective as against any Holder of Registrable Securities
unless consented to in writing by such Holder.
<PAGE>   21
                                       20

                  (d) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any air courier (i) if to a Holder, at
the most current address given by such Holder to the Company by means of a
notice given in accordance with the provisions of this Section 6(d), which
address initially is, with respect to an Initial Purchaser, the address set
forth in the Purchase Agreement; and (ii) if to the Company, initially at the
Company's address set forth in the Purchase Agreement and thereafter at such
other address, notice of which is given in accordance with the provisions of
this Section 6(d).

                  All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; at the
time received, if mailed or sent by air courier; when answered back, if telexed;
and when receipt is acknowledged, by recipient's telecopy operator, if
telecopied.

                  Copies of all such notices, demands, or other communications
shall be concurrently delivered by the Person giving the same to the Trustee, at
the address specified in the Indenture.

                  (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of each
of the parties, including, without limitation and without the need for an
express assignment, subsequent Holders; provided that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms hereof or of the Purchase Agreement or the
Indenture. If any transferee of any Holder shall acquire Registrable Securities,
in any manner, whether by operation of law or otherwise, such Registrable
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Registrable Securities, such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement, including the restrictions on resale set
forth in this Agreement and, if applicable, the Purchase Agreement, and such
Person shall be entitled to receive the benefits hereof.

                  (f) Third Party Beneficiary. The Initial Purchasers shall be
third party beneficiaries to the agreements made hereunder between the Company,
on the one hand, and the Holders, on the other hand, and shall have the right to
enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

                  (g) Counterparts. This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

                  (h) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK,

UNITED STATES OF AMERICA.
<PAGE>   22
                                       21

                  (j) Agent for Service; Submission to Jurisdiction; Waiver of
Immunities. By the execution and delivery of this Agreement, the Company (i)
acknowledges that it has, by separate written instrument, designated and
appointed CT Corporation System, 1633 Broadway, New York, New York 10019 (the
"Agent") (and any successor entity), as its authorized agent upon which process
may be served in any suit or proceeding arising out of or relating to this
Agreement, the Securities or the Exchange Securities that may be instituted in
any federal or state court in The City of New York, Borough of Manhattan, State
of New York or brought under federal or state securities laws, and acknowledges
that the Agent has accepted such designation, (ii) submits to the jurisdiction
of any such court in any such suit or proceeding and (iii) agrees that service
of process upon the Agent and written notice of said service to the Company in
accordance with Section 6(d) hereof shall be deemed in every respect effective
service of process upon the Company in any such suit or proceeding. The Company
further agrees to take any and all action, including the execution and filing of
any and all such documents and instruments, as may be necessary to continue such
designation and appointment of the Agent in full force and effect so long as any
of the Securities or Exchange Securities shall be outstanding; provided that the
Company may (and, to the extent the Agent ceases to be able to be served on the
basis contemplated herein, shall), by written notice to the Initial Purchasers
and the Holders of Securities and Exchange Securities in accordance with Section
6(d) hereof, designate such additional or alternative agent for service of
process under this Section 6(j) (including counsel to the Company) that (i)
maintains an office located in The City of New York, Borough of Manhattan, State
of New York and (ii) is a corporate service company which acts as agent for
service of process for other persons in the ordinary course of its business.
Such written notice shall identify the name of such agent for service of process
and the address of the office of such agent for service of process in The City
of New York, Borough of Manhattan, State of New York.

                  To the extent that the Company has or hereafter may acquire
any sovereign immunity from jurisdiction of any court or from any legal process
(whether through service of notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, it hereby irrevocably waives such sovereign immunity in respect of its
obligations, to the extent permitted by law, under this Agreement, the
Securities, the Exchange Securities, the Indenture (or any similar agreement
used in connection with the Exchange Offer), the Purchase Agreement or the
separate written instrument referenced in this Section 6(j).

                  (k) Judgment Currency. The Company agrees to indemnify the
Initial Purchasers, each holder of the Securities and the Exchange Securities
and each indemnified party against any loss incurred by any of them as a result
of any judgment or order being given or made for any amount due to them under
this Agreement and such judgment or order being expressed and paid in a currency
(the "Judgment Currency") other than United States dollars and as a result of
any variation as between (i) the rate of exchange at which the United States
dollar amount is converted into the judgment Currency for the purpose of such
judgment or order and (ii) the spot rate of exchange in The City of New York at
which any such Person on the date of payment of such judgment in order is able
to purchase United States dollars with the amount of the Judgment Currency
actually received by such person. The foregoing indemnity shall continue in full
force and effect notwithstanding any such judgment or order as aforesaid. The
term "spot rate of exchange" shall include any premiums and costs of exchange
payable in connection with the purchase of, or conversion into, United States
dollars.

                  (l) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

the Prospectus, dated [ ], 1996 (the "Prospectus"), of Occidente y Caribe
Celular S.A., a Colombian corporation (the "Company"), and this Letter of

"Exchange Offer") to exchange up to US$190,745,000 aggregate principal amount at
maturity of 14% Series B Senior Discount Notes due 2004 (the "New Notes"), for a
like principal amount at maturity of the Company's issued and outstanding 14%

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

         Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount at
maturity of Old Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of the Old Notes tendered hereby, the undersigned hereby
sells, assigns and transfers to, or upon the order of, the Company all right,
title and interest in and to such Old Notes as are being tendered hereby.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Old Notes
tendered hereby and that the Company will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim when the same are accepted by the Company. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Company or the Exchange Agent to be necessary or desirable to
complete the sale, assignment and transfer of the Old Notes tendered hereby.

         The undersigned also acknowledges that this Exchange Offer is being
made in reliance on an interpretation by the staff of the Securities and
Exchange Commission (the "SEC") that the New Notes issued in exchange for the
Old Notes pursuant to the Exchange Offer may be offered for resale, resold and
otherwise transferred by holders thereof (other than (i) any such holder that is
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act of 1933, as amended (the "Securities Act") or (ii) any
broker-dealer that purchase Notes from the Company to resell pursuant to Rule
144A under the Securities Act ("Rule 144A") or any other available exemption)
without compliance with the registration and prospectus delivery provisions of
the Securities Act provided that such New Notes are acquired in the ordinary
course of such holders' business and such holders have no arrangement with any
person to participate in the distribution of such New Notes. The undersigned
acknowledges that any holder of Old Notes using the Exchange Offer to
participate in a distribution of the New Notes (i) cannot rely on the position
of the staff of the SEC enunciated in its interpretive letter with respect to
Exxon Capital Holdings Corporation (available April 13, 1989) or similar letters
and (ii) must comply with the registration and prospectus delivery requirements
of the Securities Act in connection with a secondary resale transaction.

         The undersigned represents that (i) the New Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of such holder's
business, (ii) such holder has no arrangements with any person to participate in
the distribution of such New Notes, and (iii) such holder is not an "affiliate,"
as defined in Rule 405 under the Securities Act, of the Company or, if such
holder is an affiliate, that such holder will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable.

         If the undersigned is not a broker-dealer, the undersigned represents
that it is not engaged in, and does not intend to engage in, a distribution of
New Notes. If the undersigned is a broker-dealer that will receive New Notes for
its own account in exchange for Old Notes that were acquired as a result of
market-making activities or other trading, it acknowledges that it will deliver
a prospectus in connection with any resale of such New Notes; however, by so
acknowledging and by delivering a prospectus, the undersigned will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

         The undersigned, if a California resident, hereby further represents
and warrants that the undersigned (or the beneficial owner of the Old Notes
tendered hereby, if not the undersigned) (i) is a bank, savings and loan
association, trust company, insurance company, investment company registered
under the Investment Company Act of 1940, pension or profit-sharing trust (other
than a pension or profit-sharing trust of the Company, a self-employed
individual retirement plan, or individual retirement account), or a corporation
which has a net worth on a consolidated basis according to its most recent
audited financial statement of not less than $14,000,000, and (ii) is acquiring
the

                                        3
<PAGE>   4
New Notes for its own account for investment purposes (or for the account of the
beneficial owner of such New Notes for investment purposes).

         All authority conferred or agreed to be conferred in this Letter and
every obligation of the undersigned hereunder shall be binding upon the
successors, assigns, heirs, executors, administrators, trustees in bankruptcy
and legal representatives of the undersigned and shall not be affected by, and
shall survive, the death or incapacity of the undersigned. This tender may be
withdrawn only in accordance with the procedures set forth in the instructions
contained in this Letter.

         The undersigned understands that tenders of the Old Notes pursuant to
any one of the procedures described under "The Exchange Offer--Procedures for
Tendering Old Notes" in the Prospectus and in the instructions hereto will
constitute a binding agreement between the undersigned and the Company in
accordance with the terms and subject to the conditions of the Exchange Offer.

         The undersigned recognizes that, under certain circumstances set forth
in the Prospectus under "The Exchange Offer--Certain Conditions to the Exchange
Offer," the Company may not be required to accept for exchange any of the Old
Notes tendered. Old Notes not accepted for exchange or withdrawn will be
returned to the undersigned at the address set forth below unless otherwise
indicated under "Special Delivery Instructions" below.

         Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please issue the New Notes (and, if applicable, substitute
certificates representing Old Notes for any Old Notes not exchanged) in the name
of the undersigned. Similarly, unless otherwise indicated under the box entitled
"Special Delivery Instructions" below, please deliver the New Notes (and, if
applicable, substitute certificates representing Old Notes for any Old Notes not
exchanged) to the undersigned at the address shown above in the box entitled
"Description of Old Notes."

         THE BOOK-ENTRY TRANSFER FACILITY, AS THE HOLDER OF RECORD OF CERTAIN
OLD NOTES, HAS GRANTED AUTHORITY TO BOOK-ENTRY TRANSFER FACILITY PARTICIPANTS
WHOSE NAMES APPEAR ON A SECURITY POSITION LISTING WITH RESPECT TO SUCH OLD NOTES
AS OF THE DATE OF TENDER OF SUCH OLD NOTES TO EXECUTE AND DELIVER THE LETTER OF
TRANSMITTAL AS IF THEY WERE THE HOLDERS OF RECORD. ACCORDINGLY, FOR PURPOSES OF
THIS LETTER OF TRANSMITTAL, THE TERM "HOLDER" SHALL BE DEEMED TO INCLUDE SUCH
BOOK-ENTRY TRANSFER FACILITY PARTICIPANTS.

         THE UNDERSIGNED, BY COMPLETING THE BOX ENTITLED "DESCRIPTION OF OLD
NOTES" ABOVE AND SIGNING THIS LETTER AND DELIVERING SUCH NOTES AND THIS LETTER
TO THE EXCHANGE AGENT, WILL BE DEEMED TO HAVE TENDERED THE OLD NOTES AS SET

Expiration Date, or (iii) the holder of Old Notes must comply with the
guaranteed delivery procedures described below.

         The method of delivery of this Letter, the Old Notes and all other
required documents is at the election and risk of the tendering holders, but the
delivery will be deemed made only when actually received or confirmed by the
Exchange Agent. If such delivery is by mail, it is recommended that registered
mail properly insured, with return receipt requested, be used. In all cases,
sufficient time should be allowed to permit timely delivery.

         If a holder desires to tender Old Notes and such holder's Old Notes are
not immediately available or time will not permit such holder's Letter of
Transmittal, Old Notes (or a confirmation of book-entry transfer of Old Notes
into the Exchange Agent's account at the book-entry transfer facility) or other
required documents to reach the Exchange Agent on or before the Expiration Date,
such holder's tender may be effected if:

         (a) such tender is made by or through an Eligible Institution (as
      defined below);

         (b) on or prior to the Expiration Date, the Exchange Agent has received
      a telegram, facsimile transmission (receipt confirmed by telephone and an
      original delivered by guaranteed overnight courier) or letter from such
      Eligible Institution setting forth the name and address of the holder of
      such Old Notes and the principal amount of Old Notes tendered and stating
      that the tender is being made thereby and guaranteeing that, within three
      business days after the Expiration Date, a duly executed Letter of
      Transmittal, or facsimile thereof, together with the Old Notes (or a
      confirmation of book-entry transfer of such Old Notes into the Exchange
      Agent's account at the book-entry transfer facility), and any other
      documents required by this Letter and the instructions hereto, will be
      deposited by such Eligible Institution with the Exchange Agent; and

         (c) this Letter, or a facsimile hereof, and Old Notes in proper form
     for transfer (or a confirmation of book-entry transfer of such Old Notes
     into the Exchange Agent's account at the book-entry transfer facility) and
     all other required documents are received by the Exchange Agent within
     three business days after the Expiration Date.

See "The Exchange Offer--Procedures for Tendering Old Notes," "The Exchange
Offer--Book-Entry Transfer," and "The Exchange Offer--Guaranteed Delivery
Procedures" in the Prospectus.

2.   WITHDRAWALS.

         Any holder who has tendered Old Notes may withdraw the tender by
delivering written notice of withdrawal (which may be sent by telegram,
facsimile (receipt confirmed by telephone and an original delivered by
guaranteed overnight courier)) to the Exchange Agent prior to the Expiration
Date. For a withdrawal to be effective, a written notice of withdrawal sent by
telegram, facsimile transmission (receipt confirmed by telephone) or letter must
be received by the Exchange Agent prior to the Expiration Date at its address
set forth below. Any such notice of withdrawal must specify the name of the
person having tendered the Old Notes to be withdrawn, identify the Old Notes to
be withdrawn (including the amount of such Old Notes), and (where certificates
for Old Notes have been transmitted) specify the name in which such Old Notes
are registered, if different from that of the withdrawing holder thereof. If
certificates for Old Notes have been delivered or otherwise identified to the
Exchange Agent, then, prior to the release of such certificates the withdrawing
holder thereof must also submit the serial numbers of the particular
certificates to be withdrawn and a signed notice of withdrawal with signatures
guaranteed by an Eligible Institution unless such holder is an Eligible
Institution. If Old Notes have been tendered pursuant to the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Old Notes and otherwise comply with the procedures
of such facility. See "The Exchange Offer--Withdrawal Rights" in the Prospectus.

3.   SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF
     SIGNATURES.

         If this Letter is signed by the registered holder of the Old Notes
tendered hereby, the signature must correspond exactly with the name as written
on the face of the certificates without any change whatsoever.

         If any tendered Old Notes are owned of record by two or more joint
owners, all such owners must sign this Letter.

         If any tendered Old Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this Letter as there are different registrations of certificates.

         The signatures on this Letter or a notice of withdrawal, as the case
may be, must be guaranteed unless the Old Notes surrendered for exchange
pursuant thereto are tendered (i) by a registered holder of the Old Notes who
has not completed the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" in this Letter or (ii) for the account of an Eligible
Institution. In the event that the signatures in this Letter or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantees
must be by a firm which is a member of a registered national securities exchange
or a member of the National Association of Securities Dealers, Inc., a clearing
agency, an insured credit union, a savings association or by a commercial bank
or trust company having an office or correspondent in the United States
(collectively, "Eligible Institutions"). If Old Notes are registered in the name
of a person other than the signer of this Letter, the Old Notes surrendered for
exchange must be endorsed by, or be accompanied by a written instrument or
instruments of transfer or exchange, in satisfactory form as determined by the
Company in its sole discretion, duly executed by the registered holder with the
signature thereon guaranteed by an Eligible Institution.

4.   SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.

         Tendering holders of Old Notes should indicate in the applicable box
the name and address to which New Notes issued pursuant to the Exchange Offer
are to be issued or sent, if different from the name or address of the person
signing this Letter. In the case of issuance in a different name, the employer
identification or social security number of the person named must also be
indicated. If no such instructions are given, any New Notes will be issued





                                        8
<PAGE>   9
in the name of, and delivered to, the name or address of the person signing this
Letter and any Old Notes not accepted for exchange will be returned to the name
or address of the person signing this Letter.

5.   BACKUP FEDERAL INCOME TAX WITHHOLDING AND SUBSTITUTE FORM W-9.

         Under the federal income tax laws, payments that may be made by the
Company on account of New Notes issued pursuant to the Exchange Offer may be
subject to backup withholding at the rate of 31%. In order to avoid such backup
withholding, each tendering holder should complete and sign the Substitute Form
W-9 included in this Letter and either (a) provide the correct taxpayer
identification number ("TIN") and certify, under penalties of perjury, that the
TIN provided is correct and that (i) the holder has not been notified by the
Internal Revenue Service (the "IRS") that the holder is subject to backup
withholding as a result of failure to report all interest or dividends or (ii)
the IRS has notified the holder that the holder is no longer subject to backup
withholding; or (b) provide an adequate basis for exemption. If the tendering
holder has not been issued a TIN and has applied for one, or intends to apply
for one in the near future, such holder should write "Applied For" in the space
provided for the TIN in Part 1 of the Substitute Form W-9, sign and date the
Substitute Form W-9 and sign the Certificate of Payee Awaiting Taxpayer
Identification Number. If "Applied For" is written in Part 1, the Company (or
the Paying Agent under the Indenture governing the New Notes) shall retain 31%
of payments made to the tendering holder during the sixty (60) day period
following the date of the Substitute Form W-9. If the holder furnishes the
Exchange Agent or the Company with his or her TIN within sixty (60) days after
the date of the Substitute Form W-9, the Company (or the Paying Agent) shall
remit such amounts retained during the sixty (60) day period to the holder and
no further amounts shall be retained or withheld from payments made to the
holder thereafter. If, however, the holder has not provided the Exchange Agent
or the Company with his or her TIN within such sixty (60) day period, the
Company (or the Paying Agent) shall remit such previously retained amounts to
the IRS as backup withholding. In general, if a holder is an individual, the
taxpayer identification number is the Social Security number of such individual.
If the Exchange Agent or the Company is not provided with the correct taxpayer
identification number, the holder may be subject to a $50 penalty imposed by the
IRS. Certain holders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, such holder must submit a statement (generally, IRS Form W-8), signed
under penalties of perjury, attesting to that individual's exempt status. Such
statements can be obtained from the Exchange Agent. For further information
concerning backup withholding and instructions for completing the Substitute
Form W-9 (including how to obtain a taxpayer identification number if you do not
have one and how to complete the Substitute Form W-9 if Old Notes are registered
in more than one name), consult the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9.

         Failure to complete the Substitute Form W-9 will not, by itself, cause
Old Notes to be deemed invalidly tendered, but may require the Company (or the
Paying Agent) to withhold 31% of the amount of any payments made on account of
the New Notes. Backup withholding is not an additional federal income tax.
Rather, the federal income tax liability of a person subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained.

6.   TRANSFER TAXES.

         The Company will pay all transfer taxes, if any, applicable to the
transfer of Old Notes to it or its order pursuant to the Exchange Offer. If,
however, New Notes and/or substitute Old Notes not exchanged are to be delivered
to, or are to be registered or issued in the name of, any person other than the
registered holder of the Old Notes tendered hereby, or if tendered Old Notes are
registered in the name of any person other than the person signing this Letter,
or if a transfer tax is imposed for any reason other than the transfer of Old
Notes to the Company or its order pursuant to the Exchange Offer, the amount of
any such transfer taxes (whether imposed on the registered





                                        9
<PAGE>   10
holder or any other persons) will be payable by the tendering holder. If
satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted herewith, the amount of such transfer taxes will be billed directly to
such tendering holder.

         Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes specified in this Letter.

7.   WAIVER OF CONDITIONS.

         The Company reserves the absolute right to waive satisfaction of any or
all conditions enumerated in the Prospectus.

8.   NO CONDITIONAL TENDERS.

         No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Old Notes, by execution of this Letter, shall
waive any right to receive notice of the acceptance of their Old Notes for
exchange.

         Neither the Company nor any other person is obligated to give notice of
defects or irregularities in any tender, nor shall any of them incur any
liability for failure to give any such notice.

9.   INADEQUATE SPACE.

         If the space provided herein is inadequate, the aggregate principal
amount of Old Notes being tendered and the certificate number or numbers (if
applicable) should be listed on a separate schedule attached hereto and
separately signed by all parties required to sign this Letter.

10.  MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES.

         If any certificate has been lost, mutilated, destroyed or stolen, the
holder should promptly notify The Bank of New York, as Exchange Agent, at the
address indicated above. The holder will then be instructed as to the steps that
must be taken to replace the certificate(s). This Letter of Transmittal and
related documents cannot be processed until the Old Notes have been replaced.

11.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

         Questions relating to the procedure for tendering, as well as requests
for additional copies of the Prospectus and this Letter may be directed to the
Exchange Agent at the address and telephone number indicated above.

recipients are required to file tax returns. Payers must generally withhold 31%
of taxable interest, dividends, and certain other payments to a payee who does
not furnish a taxpayer identification number to a payer. Certain penalties may
also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER--If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.

(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, your are subject to a penalty of $500.

(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

Ladies and Gentlemen:

         Occidente y Caribe Celular S.A. (the "Company"), a sociedad anonima de
economia mixta existing under the laws of the Republic of Colombia ("Colombia"),
proposes to issue and sell to each of Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") and ING Baring (U.S.) Securities, Inc. (each an
"Initial Purchaser" and together the "Initial Purchasers") 190,745 units (the
"Units") consisting of (x) US$190,745,000 aggregate principal amount at maturity
of the Company's 14% Senior Discount Notes due 2004 (the
<PAGE>   3
                                        2

"Notes") and (y) 762,980 warrants (the "Warrants") entitling the holders thereof
to purchase, under certain circumstances, an aggregate of 4,355,852 shares of
class B common stock, par value one thousand Pesos per share, of the Company
(the "Class B Common Stock"), subject to adjustment (the "Warrant Shares"),
either as (i) American Depositary Receipts ("ADRs"), or (ii) if ADRs are not
available, such Warrant Shares. The Notes are to be issued pursuant to an
indenture to be dated as of June 1, 1996 (the "Indenture") between the Company
and The Bank of New York, as trustee (the "Trustee"). The Warrants are to be
issued pursuant to a warrant agreement to be dated as of June 7, 1996, in
substantially the form attached hereto as Exhibit A with such changes as shall
be agreed to by the parties hereto (the "Warrant Agreement") between the Company
and The Bank of New York, as warrant agent (the "Warrant Agent"). The Notes and
the Warrants will initially be represented by 762,980 Units, each Unit
consisting of US$1,000 principal amount at maturity of the Notes and 4 Warrants,
each Warrant entitling the holder thereof to purchase 5.709 shares of Class B
Common Stock, at a price of US$1.00 per share (or, if greater, the U.S. dollar
equivalent of 1,000 Pesos) either as ADRs (each ADR representing 25 shares of
Class B Common Stock), or, in certain circumstances as set forth in the Offering
Memorandum, such Warrant Shares. If a holder of Warrants exercises such Warrants
for ADRs and the number of Warrant Shares entitled to be so purchased by such
holder is not a multiple of 25, the Company will pay to the holder of such
Warrants at the time of exercise an amount in cash equal to the then current
market value of that number of shares that exceeds the largest possible multiple
of 25. The Notes, the Warrants and the Units are collectively referred to herein
as the "Securities." The Securities, the Indenture and the Warrant Agreement are
more fully described in the Offering Memorandum (as hereinafter defined).
Capitalized terms used herein and not otherwise defined herein have the
respective meanings specified in the Offering Memorandum.

         The Securities will be offered and sold to the Initial Purchasers
without being registered under the Securities Act of 1933, as amended (the "1933
Act"), in reliance on an exemption therefrom. The Company has prepared a
preliminary offering memorandum, dated May 9, 1996 (such preliminary offering
memorandum being hereinafter referred to as the "Preliminary Offering
Memorandum"), and is preparing a final offering memorandum, dated May 31, 1996
(such final offering memorandum, in the form first furnished to the Initial
Purchasers for use in connection with the offering of the Securities, being
hereinafter referred to as the "Offering Memorandum"), each setting forth
information regarding the Company and the Securities. The Company hereby
confirms that it has authorized the use of the Preliminary Offering Memorandum
and the Offering Memorandum to the extent described therein in connection with
the offering and resale of the Securities.

         The Company understands that the Initial Purchasers propose to make an
offering of the Securities only on the terms set forth in the Offering
Memorandum, as soon
<PAGE>   4
                                        3

as they deem advisable after this Agreement has been executed and delivered, (i)
to persons in the United States whom the Initial Purchasers reasonably believe
to be qualified institutional buyers ("Qualified Institutional Buyers") as
defined in Rule 144A under the 1933 Act, as such rule may be amended from time
to time ("Rule 144A"), in transactions under Rule 144A, (ii) to a limited number
of other institutional "accredited investors" (as defined in Rule 501(a)(1),
(2), (3) or (7) under Regulation D ("Regulation D") of the 1933 Act ("Accredited
Investors")) in exempt private sales under the 1933 Act and/or (iii) to non-U.S.
persons outside the United States to whom the Initial Purchasers reasonably
believe offers and sales of the Securities may be made in reliance upon
Regulation S ("Regulation S") under the 1933 Act in transactions meeting the
requirements of Regulation S.

         The holders of the Notes will be entitled to the benefits of a
registration rights agreement, in substantially the form attached hereto as
Exhibit B with such changes as shall be agreed to by the parties hereto (the
"Notes Registration Rights Agreement"), pursuant to which the Company will file
a registration statement (the "Registration Statement") with the Securities and
Exchange Commission (the "Commission") registering the Notes or the Exchange
Notes referred to in the Notes Registration Rights Agreement under the 1933 Act.
The Initial Purchasers and other holders of the Warrants will have, with respect
to the Warrants, the registration rights set forth in the Warrant Agreement.

         Section 1. Representations and Warranties. (a) The Company represents
and warrants to and agrees with the Initial Purchasers as of the date hereof and

         include an untrue statement of a material fact or omitted or will omit
         to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading; except that this representation and warranty does not
         apply to statements or omissions made in the Preliminary Offering
         Memorandum that are corrected in the Offering Memorandum or any
         amendment or supplement thereto or to statements or omissions made in
         reliance upon and in conformity with information furnished in writing
         to the Company by the Initial Purchasers expressly for use in the

         quotation system.

                  (iii) There is no "substantial U.S. market interest" (as such

         the same class or series as the Securities.

         warranties of the Initial Purchasers in Section 2 hereof and (B) the
         due performance by the Initial Purchasers of the covenants and
         agreements set forth in Section 2 hereof, none of the Company or any

         the Company or any person acting on behalf thereof has engaged in any
         directed selling efforts (as such term is defined in Regulation S) with
         respect to any Securities offered and sold in reliance on Rule 903 of
         Regulation S, and the Company and such affiliates and such other
         persons acting on behalf thereof have complied with the offering
         restrictions requirement of Regulation S with respect to the
         Securities.

                  (v) Assuming (A) the accuracy of the representations and

         affiliate of the Company (as defined in Rule 501(b) under the 1933 Act)
         has directly or through any agent, sold, offered for sale, solicited
         offers to buy or otherwise negotiated in respect of, any security (as
         defined in the 1933 Act) by or for the Company that are of the same or
         similar class as the Securities (other than with respect to the
         Exchange Notes) in a manner that would require the registration of the
         Securities under the 1933 Act.

                  (vi) Assuming (A) the accuracy of the representations and
         warranties of the Initial Purchasers in Section 2 hereof and (B) the
         due performance by the Initial Purchasers of the covenants and
         agreements set forth in Section 2 hereof, none of the Company or any
         affiliate of the Company or any person acting on their behalf has (x)
         engaged, in connection with the offering of the Securities, in any form
         of general solicitation or general advertising (as those terms are used
         within the meaning of Regulation D); or (y) solicited offers for, or
         offered or sold, such Securities by means of any form of general
         solicitation or general advertising (as those terms are used in
         Regulation D under the 1933 Act) or in any manner involving a public
         offering within the meaning of Section 4(2) of the 1933 Act.

         assumptions used in the preparation thereof are reasonable and the
         adjustments used therein are appropriate to give effect to the
         transactions or circumstances referred to therein.

                  (ix) The Company is a sociedad anonima de economia mixta duly
         organized and existing under the laws of Colombia with the requisite

         extent that the failure to so qualify or be in good standing would not
         have a material adverse effect on the Company; and the Company has no
         subsidiaries.

                  (x) The Company does not, directly or indirectly, own any

         properties and to carry on its business as presently conducted, and the
         Company has not received any notice of proceedings relating to
         revocation or modification in any materially adverse respect of any
         such concessions, licenses, permits, certificates, consents, orders,

         adequate patents, patent licenses, trademarks, service marks and
         service and trade names necessary to carry on its business as presently
         conducted (collectively, "Intellectual Property"), and the Company has
         not received any notice of infringement of or conflict with asserted
         rights of others with respect to any Intellectual Property that in the
         aggregate, if the subject of an unfavorable decision, ruling or
         finding, could result in any Material Adverse Change.

                  (xxix) To the best knowledge of the Company, no labor problem
         exists with its employees or is imminent that could result in any
         Material Adverse Change.

         Registration Rights Agreement and the Warrant Agreement and any other
         document required to be furnished hereunder or thereunder is in proper
         legal form under the laws of Colombia for the enforcement thereof
         against the Company in Colombia without further action on the part of
         the Initial Purchasers, the Trustee or the Warrant Agent (provided that
         an official Spanish translation of any agreement or instrument is
         required to bring an action thereon in the courts of Colombia); and to
         ensure the validity, enforceability or admissibility in evidence in
         Colombia of this Agreement, the Indenture, the Notes, the Notes
         Registration Rights Agreement, the Warrant Agreement, the Warrants or
         any other document required to be furnished hereunder or thereunder, it
         is not necessary that this Agreement, the Indenture, the Notes, the
         Notes Registration Rights Agreement, the Warrant Agreement, the
         Warrants or such related document be submitted to or filed or recorded
         with any court or governmental agency or body in Colombia, with the
         exception of the registration of the terms of the Notes and the
         Warrants with Banco de la Republica which will have been obtained at or
         prior to the Closing Time, or any tax, imposition or charge be paid on
         or in respect of this Agreement, the Indenture, the Notes, the Notes
         Registration Rights Agreement, the Warrant Agreement, the Warrants or
         such related document with respect to the institution of any judicial
         proceeding to enforce such agreement or instrument in Colombia or to
         obtain an exequatur in order to be able to enforce the foreign judgment
         in Colombia.

                  (xxxi) No event with respect to the Company has occurred and
         is continuing which, upon issuance of the Notes, the Warrants or the
         Units would (whether or not with the giving of notice and/or the
         passage of time and/or the fulfillment of any other requirement)
         constitute an event of default, or breach under, as described in the
         Indenture or the Warrant Agreement, respectively.

                  (xxxii) The Company is subject to civil and commercial law
         with respect to its obligations hereunder, and the execution, delivery
         and performance of this Agreement, the Indenture, the Notes, the Notes
         Registration Rights Agreement, the Warrant Agreement and the Warrants
         by the Company constitute private and commercial acts rather than
         public or governmental acts. Neither the Company nor any of its
         properties has any sovereign immunity from jurisdiction or suit of any
         court or from set-off or from any legal process or remedy (whether
         through service, notice, attachment prior to judgment, attachment in
         aid of execution, execution or otherwise) under the laws of Colombia.

                  (xxxiii) The Company has not taken and will not take, directly
         or indirectly, any action designed to, or that might reasonably be
         expected to, cause or result in stabilization or manipulation of the
         price of the Securities.

                  (xxxiv) Assuming (A) the accuracy of the representations and
         warranties of the Initial Purchasers in Section 2 hereof and (B) the
         due performance by the Initial Purchasers of the covenants and
         agreements set forth in Section 2 hereof, it is not necessary in
         connection with the offer, sale and delivery of the Securities to the
         Initial Purchasers under, or in connection with the initial resale of
         such Securities by the Initial Purchasers in accordance with, this
         Agreement to register the Securities under the 1933 Act or to qualify
         any indenture in respect of the Securities under the Trust Indenture
         Act of 1939, as amended (the "Trust Indenture Act").

                  (xxxv) The Company has complied with all applicable provisions
         of Florida H.B. 1771, codified as Section 517.057 of the Florida
         Statutes, and all regulations promulgated thereunder relating to
         issuers doing business in Cuba.

                  (xxxvi) No part of the proceeds of the sale of the Securities

                                       13

         taxes due pursuant to such returns or pursuant to any assessment
         received by the Company, except for such taxes, if any, as are being
         contested in good faith and as to which adequate reserves have been
         provided. The charges, accruals and reserves on the books of the
         Company in respect of any income and corporation tax liability for any
         years not finally determined are adequate to meet any assessments or
         re-assessments for additional income tax for any years not finally
         determined, except to the extent of any inadequacy that would not
         result in any Material Adverse Change and such as do not materially
         adversely affect the ability of the Company to repay the Notes on a
         timely basis. Except as described in the Offering Memorandum, there are
         no disputes pending or, to its knowledge, threatened, between the

         of the date hereof, no income, stamp or other taxes or levies, imposts,
         deductions, charges, compulsory loans or withholdings whatsoever are or

         collected by Colombia or any political subdivision or taxing authority
         thereof or therein or on or in respect of principal, interest,
         premiums, dividends or other distributions and penalties or other
         amounts payable under the Notes and, if issued, the Exchange Notes, the
         Warrants or the Warrant Shares or on account of this Agreement or any
         payments hereunder.

         under the Indenture and the Notes issued thereunder, are and shall at

         ranking pari passu in right of payment with all other existing and
         future unsecured and unsubordinated indebtedness of the Company
         outstanding from time to time (other than obligations preferred by
         statute or operation of law).

                  (xl) Except as described in the Offering Memorandum, it is not
         necessary under the laws of Colombia that any of the holders of the
         Securities be licensed, qualified or entitled to carry on business in
         Colombia by reason solely of the execution, delivery, performance or
         enforcement of this Agreement, the Indenture, the Notes Registration
         Rights Agreement or the Warrant Agreement.

                  (xli) Except as described in the Offering Memorandum,
         non-Colombian holders of Notes or Warrants will not be deemed resident,

         solely by reason of the execution, delivery, performance or enforcement
         of this Agreement, the Indenture, the Notes Registration Rights
         Agreement or the Warrant Agreement, except as described in the

         registration and regulations, as described in the Offering Memorandum.

                  (xlii) The Company maintains a system of internal accounting
         controls sufficient to provide reasonable assurances that (A)
         transactions are generally executed in accordance with management's

         an "investment company," as such terms are defined in the Investment
         Company Act of 1940, as amended (the "1940 Act").

                  (xlv) Except as disclosed in the Offering Memorandum and

         Claims against the Company, and (D) there are no circumstances with
         respect to any property or operations of the Company that could

such transfer of Units is effected by the delivery to such purchaser of Units in
definitive form and registered in its name (or its nominee's name) on the books

                  (a) The Company will not at any time make any amendment or
         supplement to the Offering Memorandum of which the Initial Purchasers
         shall not have previously been advised and furnished a copy or to which
         the Initial Purchasers or the Initial Purchasers' counsel shall
         reasonably object.

                  (b) The Company will promptly deliver to the Initial
         Purchasers, without charge, during the period from the date hereof to
         the date of the completion of the distribution of the Securities by the

         Memorandum, as it may then be amended or supplemented, as the Initial
         Purchasers may reasonably request.

                  (c) If, at any time prior to completion of the distribution of
         the Securities by the Initial Purchasers, any event shall occur or
         condition exist as a result of which it is necessary, in the opinion of
         the Initial Purchasers' counsel or counsel for the Company, to amend or
         supplement the Offering Memorandum in order that the Offering
         Memorandum will not include an untrue statement of a material fact or
         omit to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances existing at the time it is
         delivered to a purchaser, not misleading or if, in the opinion of the

<PAGE>   19
                                       18

         is necessary to amend or supplement the Offering Memorandum to comply
         with applicable law, the Company, at its own expense, will promptly
         prepare such amendment or supplement as may be necessary so that the
         statements in the Offering Memorandum as so amended or supplemented
         will not, in the light of the circumstances existing at the time it is
         delivered to a purchaser, be misleading or so that such Offering
         Memorandum as so amended or supplemented will comply with applicable
         law, as the case may be, and furnish the Initial Purchasers such number
         of copies as the Initial Purchasers may reasonably request.

                  (d) The Company will endeavor, in cooperation with the Initial
         Purchasers, to qualify the Securities for offering and sale under the
         applicable securities laws of such states and other jurisdictions as
         the Initial Purchasers may reasonably designate and to maintain such
         qualifications in effect for a period of not less than a year from the
         date of the Offering Memorandum; provided, however, that the Company
         shall not be obligated to file any general consent to service of
         process or to qualify as a foreign corporation or as a dealer in
         securities in any jurisdiction in which it is not so qualified or to
         subject itself to taxation in respect of doing business in any
         jurisdiction in which it is not otherwise so subject. The Company will
         file such statements and reports as may be required by the laws of each
         jurisdiction in which the Securities have been qualified as above
         provided. The Company will also supply the Initial Purchasers with such
         information as is necessary for the determination of the legality of
         the Securities for investment under the laws of such jurisdictions as
         the Initial Purchasers may reasonably request.

                  (e) Except following the effectiveness of the Registration
         Statement and pursuant to the terms thereof, neither the Company nor
         any of its affiliates (as such term is defined in Rule 501(b) of
         Regulation D) will solicit any offer to buy or offer to sell the
         Securities by means of any form of general solicitation or general
         advertising (within the meaning of Rule 502(c) of Regulation D) or in
         any manner involving a public offering within the meaning of Section
         4(2) of the 1933 Act.

                  (f) Except following the effectiveness of the Registration
         Statement and pursuant to the terms thereof, the Company will not and
         will request its affiliates (as such term is defined in Rule 501(b) of
         the 1933 Act) not to offer, sell or solicit offers to buy or otherwise
         negotiate in respect of any security (as defined in the 1933 Act) the
         offering of which security could be integrated with the sale of the
         Securities in a manner that would require the registration of any of
         the Securities under the 1933 Act.

<PAGE>   20
                                       19

         company, unit investment trust or face-amount certificate company that
         is or is required to be registered under the 1940 Act, and will not be
         or become a closed-end investment company required to be registered,
         but not registered, thereunder.

                  (h) During the period from the Closing Time to the earlier of
         (i) three years after the Closing Time or (ii) the date of
         effectiveness of the Registration Statement, the Company will not, and
         will request its affiliates (as such term is defined in Rule 144 under
         the 1933 Act) not to, resell any of the Securities that have been
         reacquired thereby, except for Securities purchased by the Company or
         any of its affiliates and resold in a transaction registered under the
         1933 Act.

                  (i) The Company will file with the Trustee and provide the
         holders of Notes, within 15 days after it files them with the
         Commission, copies of its annual and quarterly reports and other
         information, documents and other reports (or copies of such portions of
         any of the foregoing as the Commission may by rules and regulations
         prescribe) which the Company is required to file with the Commission
         pursuant to Section 13(a) or 15(d) of the 1934 Act. Notwithstanding
         that the Company may not be required to remain subject to the reporting
         requirements of Section 13(a) or 15(d) of the 1934 Act or otherwise
         report on an annual and quarterly basis on forms provided for such
         annual and quarterly reporting pursuant to rules and regulations
         promulgated by the Commission, the Company will file with or furnish to
         the Commission and provide to the Trustee and to the holders of Notes
         and potential purchasers of Notes upon written request to the Trustee

         to be contained in Form 10-Q (or required in any successor form); and
         (iii) promptly from time to time after the occurrence of an event
         required to be therein reported, such other reports on Form 6-K (or any
         successor form) containing substantially the same information required
         to be contained in Form 8-K (or required in any successor form). Prior
         to the filing of the Registration Statement with the Commission and in
         the event that the Company never becomes subject to the reporting
         requirements of Section 13(a) or 15(d) of the 1934 Act, the Company
         will provide to the Trustee and to the holders of Notes, and potential
         purchasers of Notes upon written request to the Trustee by any holder
         of Notes, potential purchaser of Notes or Initial Purchaser, all of the

         such time as the Company would have been required to provide such
         information to the Commission pursuant to such clauses (i), (ii) and
         (iii) above. Financial statements of the Company contained in any such
         report will be prepared in accordance with Colombian GAAP and each such
         report referred to in clauses (i) and (ii) above will contain a
         reconciliation to U.S. GAAP consistently applied and will be prepared
         in accordance with the applicable rules and regulations of the
         Commission. For a period of four years after the Closing Time, the
         Company will make available to the Initial Purchasers upon request
         copies of all such documents, reports and information, except with
         respect to such documents, reports and information, or portions
         thereof, which were made as confidential submissions to the Commission
         together with such other documents, reports and information as shall be
         furnished by the Company to the holders of the Notes issued by it.

                  (j) If requested by the Initial Purchasers, the Company will
         use its best efforts in cooperation with the Initial Purchasers to (i)
         permit the Securities sold in transactions described in Sections

         the laws of Colombia and of the State of New York and the federal law
         of the United States, upon opinions of other counsel, who shall be
         counsel reasonably satisfactory to United States counsel for the
         Initial Purchasers, in which case the opinion shall state that they
         believe the Initial Purchasers are entitled to so rely. Such counsel
         may also state that, insofar as such opinion involves factual matters,
         they have relied, to the extent they deem proper, upon the
         representations and warranties of the Company set forth in this
         Agreement and certificates of officers of the Company and certificates
         of public officials; provided that such certificates have been
         delivered to the Initial Purchasers.

                  (b) At the Closing Time, each of the Initial Purchasers shall
         have received a signed opinion of Mauricio Campillo Orozco, General
         Counsel to the Company, dated as of the Closing Time, in substantially
         the form attached hereto as Exhibit D. Such opinion shall be to such
         further effect with respect to other legal matters relating to this
         Agreement and the sale of the Securities pursuant to this Agreement as
         counsel for the Initial Purchasers may reasonably request. In giving
         such opinion, such counsel may rely upon the opinion of Cravath, Swaine
         & Moore as to all matters governed by the laws of the State of New York
         and the federal law of the United States, and the Initial Purchasers
         are entitled to rely thereon.

                  (c) At the Closing Time, each of the Initial Purchasers shall
         have received a signed opinion of Holguin, Neira y Pombo, special
         Colombian counsel to the Company, dated as of the Closing Time, in
         substantially the form attached hereto as Exhibit E. Such opinion shall
         be to such further effect with respect to other legal matters relating
         to this Agreement and the sale of the Securities pursuant to this
         Agreement as United States counsel for the Initial Purchasers may
         reasonably request. In giving such opinion, such counsel may rely upon
         the opinion of Cravath, Swaine & Moore as to all matters governed by
         the laws of the State of New York and the federal law of the United
         States, and the Initial Purchasers are entitled to rely thereon. Such
         counsel may also state that, insofar as such opinion involves factual
         matters, they have relied, to the extent they deem proper, upon the
         representations and warranties of the Company set forth in this
         Agreement and certificates of officers of the Company and certificates
         of public officials; provided that such certificates have been
         delivered to the Initial Purchasers.

                  (d) At the Closing Time, each of the Initial Purchasers shall
         have received a signed opinion of Dunnington, Bartholow & Miller,
         counsel to the Trustee and the Warrant Agent, dated as of the Closing
         Time, in substantially the form attached hereto as Exhibit F. Such
         opinion shall be to such further effect with respect to other legal
         matters relating to the sale of the Securities, the Indenture and the
         Warrant Agreement as United States counsel for the Initial Purchasers
         may reasonably request.

                  (e) At the Closing Time, each of the Initial Purchasers shall
         have received a signed opinion of Brigard & Urrutia Abogados, Colombian
         counsel to the Initial Purchasers, dated as of the Closing Time. Such
         opinion shall be to such further effect with respect to other legal
         matters relating to this Agreement and the sale of the Securities
         pursuant to this Agreement as United States counsel for the Initial
         Purchasers may reasonably request. In giving such opinion, such counsel
         may rely, upon the opinion of Shearman & Sterling as to all matters
         governed by the laws of the State of New York and the federal law of
         the United States, and the Initial Purchasers are entitled to rely
         thereon. Such counsel may also state that, insofar as such opinion
         involves factual matters, they have relied, to the extent they deem
         proper, upon the representations and warranties of the Company set
         forth in this Agreement and certificates of officers of the Company and
         certificates of public officials; provided that such certificates have
         been delivered to the Initial Purchasers.

                  (f) At the Closing Time, each of the Initial Purchasers shall
         have received the favorable opinion of Shearman & Sterling, United
         States counsel for the Initial Purchasers, dated as of the Closing
         Time, to the effect that the opinions delivered pursuant to Sections
         5(a), 5(b), 5(c), 5(d) and 5(e) appear on their face to be

<PAGE>   27
                                       26

         appropriately responsive to the requirements of this Agreement except,
         specifying the same, to the extent waived by the Initial Purchasers,
         and with respect to the Securities, the Indenture, the Notes
         Registration Rights Agreement, the Warrant Agreement, the Offering
         Memorandum and such other related matters as the Initial Purchasers may
         require. In giving such opinion such counsel may rely, as to all
         matters governed by laws other than the law of the State of New York
         and the federal law of the United States, upon the opinions of counsel
         satisfactory to the Initial Purchasers. Such counsel may also state
         that, insofar as such opinion involves factual matters, they have
         relied, to the extent they deem proper, upon the representations and
         warranties of the Company set forth in this Agreement and certificates
         of officers of the Company and certificates of public officials;
         provided that such certificates have been delivered to the Initial
         Purchasers.

                  (g) At the Closing Time, (i) the Offering Memorandum, as it
         may then be amended or supplemented, shall not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading, (ii) there shall not have been, since the respective dates
         as of which information is given in the Offering Memorandum, any
         Material Adverse Change, whether or not arising in the ordinary course
         of business, (iii) no action, suit or proceeding at law or in equity
         shall be pending or, to the knowledge of the Company, threatened
         against the Company that would be required to be set forth in the
         Offering Memorandum other than as set forth therein and no proceedings
         shall be pending or, to the knowledge of the Company, threatened
         against the Company before or by any government, governmental
         instrumentality, court or arbitrator, domestic or foreign, that could
         reasonably result in any material adverse change in the condition
         (financial or otherwise), earnings, business affairs or business
         prospects of the Company other than as set forth in the Offering
         Memorandum, (iv) the Company shall have in all material respects
         complied with all agreements and satisfied all conditions on its part
         to be performed or satisfied at or prior to the Closing Time, (v) no
         event of default shall exist under any contract, indenture, mortgage,
         loan agreement, note, lease or other agreement or instrument to which
         the Company is a party or to which the Company is subject that in the
         aggregate could result in a Material Adverse Change and (vi) the other
         representations and warranties of the Company set forth in Section 1(a)
         shall be accurate in all material respects as though expressly made at
         and as of the Closing Time. At the Closing Time, each of the Initial
         Purchasers shall have received a certificate of the President and the
         Financial Vice President of the Company, dated as of the Closing Time,
         to such effect.

                  (h) At the time that this Agreement is executed by the
         Company, each of the Initial Purchasers shall have received from KPMG
         Peat Marwick, independent auditors for the Company, a letter, dated
         such date, in form and substance satisfactory to the Initial
         Purchasers, confirming that they are independent auditors with respect
         to the Company within the meaning of the standards established for
         independent public accountants in Colombia and under rule 101 of the
         AICPA's Code of Professional Conduct, and its interpretations and
         rulings, and stating in effect that:

                           (i) on the basis of procedures (but not an audit in
                  accordance with generally accepted auditing standards)
                  consisting of a reading of the latest available unaudited
                  interim consolidated financial statements of the Company
                  included in the Offering Memorandum, a reading of the minutes
                  of all meetings of the stockholders and directors of the
                  Company and the Financial Committee of the Company's Board of
                  Directors from January 1 to May 27, 1996 (except for those
                  meetings for which minutes have not yet been provided, in
                  which case minutes for such meetings in draft form have been
                  read) inquiries of certain officials of the Company
                  responsible for financial and accounting matters, and such
                  other inquiries and procedures as may be specified in such
                  letter, nothing came to their attention that caused them to
                  believe that:

                                    (A) at a specified date not more than five
                           days prior to the date of this Agreement, there was
                           any change in the capital stock of the Company or
                           increase in long-term debt, in each case as compared
                           with amounts shown on the March 31, 1996 unaudited
                           condensed balance sheet included in the Offering
                           Memorandum, except in each case for such changes or
                           decreases that the Offering Memorandum discloses have
                           occurred or may occur; or

                                    (B) for the period from April 1, 1996 to a
                           specified date not more than five days prior to the
                           date of this Agreement, there was as compared with
                           the comparable period in the preceding year, any
                           decrease in net revenues, or any increase in the
                           total or per share amounts of net loss, except in
                           each case for such decreases or increases that the
                           Offering Memorandum discloses have occurred or may
                           occur;

                           (ii) in addition to the procedures referred to in
                  clause (i) above, they have performed other specified
                  procedures, not constituting an audit, with respect to certain
                  amounts, percentages, numerical data and financial information
                  appearing in the Offering Memorandum, including the Selected

<PAGE>   29
                                       28

                  Financial Information, which have previously been specified by
                  the Initial Purchasers and which shall be specified in such
                  letter, and have compared certain of such items with, and have
                  found such items to be in agreement with, the accounting and
                  financial records of the Company.

                  (i) At the Closing Time, each of the Initial Purchasers shall
         have received from KPMG Peat Marwick a letter, in form and substance
         satisfactory to the Initial Purchasers and dated as of the Closing
         Time, to the effect that they reaffirm the statements made in the
         letter furnished pursuant to Section 5(h), except that the specified
         date referred to shall be a date not more than five days prior to the
         Closing Time.

                  (j) Subsequent to the execution and delivery of this Agreement
         and prior to the Closing Time, there shall not have been any
         downgrading, nor any notice given of any intended or potential
         downgrading or of a possible change that does not indicate the
         direction of the possible change, in the rating accorded any of the
         Company's securities, including the Securities, by any "nationally
         recognized statistical rating organization," as such term is defined
         for purposes of Rule 436(g)(2) under the 1933 Act.

                  (k) At the Closing Time, counsel for the Initial Purchasers
         shall have been furnished with all such documents, certificates and
         opinions as they may reasonably request for the purpose of enabling
         them to pass upon the issuance and sale of the Securities as
         contemplated in this Agreement and the matters referred to in Section
         5(f) and in order to evidence the accuracy and completeness of any of
         the representations, warranties or statements of the Company, the
         performance of any of the covenants of the Company, or the fulfillment
         of any of the conditions herein contained; and all proceedings taken by
         the Company at or prior to the Closing Time in connection with the
         authorization, issuance and sale of the Securities as contemplated in
         this Agreement shall be reasonably satisfactory in form and substance
         to the Initial Purchasers and to counsel for the Initial Purchasers.

                  (l) At the Closing Time, the Notes Registration Rights
         Agreement, the Indenture and the Warrant Agreement shall have been
         fully executed and be in full force and effect.

                  (m) At the Closing Time, the Credit Agreement among the
         Company, ING Bank, N.V., ING Baring (U.S.) Securities Corporation,
         Merrill Lynch and the other Lenders thereto shall have been fully
         executed and registered with Banco de la Republica and be in full force
         and effect, the proceeds thereunder shall have been

<PAGE>   30
                                       29

         simultaneously disbursed and such proceeds shall have been
         simultaneously utilized for the purposes described in the Offering
         Memorandum under the caption "Use of Proceeds."

                  (n) At or before the Closing Time, the Initial Purchasers
         shall have received a copy of the resolution of the Colombian
         Superintendency of Corporations approving the issuance of the Notes and
         the Warrants.

                  (o) At or before the Closing Time, the terms of the Notes and
         the Warrants shall have been duly registered with Banco de la
         Republica, and the Initial Purchasers shall have received a copy of
         such registration.

                  (p) CT Corporation System shall have accepted its appointment
         as Process Agent pursuant to Section 14, and the Initial Purchasers
         shall have received a letter from the Process Agent evidencing such
         acceptance.

                  If any of the conditions specified in this Section 5 shall not
have been fulfilled when and as required by this Agreement, this Agreement may
be terminated by the Initial Purchasers on notice to the Company at any time at
or prior to the Closing Time, and such termination shall be without liability of
any party to any other party, except as provided in Section 4. Notwithstanding
any such termination, the provisions of Sections 6, 7 and 8 shall remain in
effect.

                  Section 6. Indemnification. (a) The Company agrees to
indemnify and hold harmless the Initial Purchasers and each person, if any, who
controls the Initial Purchasers within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact included in any preliminary
         offering memorandum or the Offering Memorandum (or any amendment or
         supplement thereto) or the omission or alleged omission therefrom of a
         material fact necessary in order to make the statements therein, in the
         light of the circumstances under which they were made, not misleading;

                  (ii) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission;

<PAGE>   31
                                       30

         provided that (subject to Section 6(d) below) any such settlement is
         effected with the written consent of the Company; and

                  (iii) against any and all expense whatsoever, as incurred
         (including fees and disbursements of United States and Colombian
         counsel chosen by Merrill Lynch), reasonably incurred in investigating,
         preparing or defending against any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or any claim whatsoever, based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission, to the
         extent that any such expense is not paid under subparagraph (i) or (ii)
         above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Initial Purchaser through Merrill Lynch expressly for use in the Offering
Memorandum (or any amendment or supplement thereto), or any preliminary offering
memorandum; provided further that the foregoing indemnification with respect to
any preliminary offering memorandum shall not inure to the benefit of any
Initial Purchaser (or any person controlling such Initial Purchaser) from whom
the person asserting any such losses, claims, damages or liabilities purchased
any of the Units if a copy of the Offering Memorandum (as then amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) was not sent or given by or on behalf of such Initial Purchaser on the
initial resale to such person, at or prior to the written confirmation of the
sale of such Units to such person and if the Offering Memorandum (as so amended
or supplemented) would have cured the defect giving rise to such loss, claim,
damage or liability.

                  (b) Each Initial Purchaser severally (but not jointly) agrees
to indemnify and hold harmless the Company, its directors, each of its officers
and each person, if any, who controls the Company within the meaning of Section
15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss,
liability, claim, damage and expense described in the indemnity agreement in
subsection (a) of this Section, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in any
preliminary offering memorandum or the Offering Memorandum (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
furnished to the Company by such Initial Purchaser through Merrill Lynch
expressly for use in such preliminary offering memorandum or the Offering
Memorandum (or any amendment or supplement thereto).

                                       31

                  (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. In the case of
parties indemnified pursuant to Section 6(a) above, counsel to the indemnified
parties shall be selected by Merrill Lynch, and, in the case of parties
indemnified pursuant to Section 6(b) above, counsel to the indemnified parties
shall be selected by the Company. An indemnifying party may participate at its
own expense in the defense of such action provided, however, that counsel to the
indemnifying party shall not (except with the consent of indemnified party) also
be counsel to the indemnified party. In no event shall the indemnifying parties
be liable for fees and expenses of more than one counsel (in addition to any
Colombian counsel) separate from their own counsel for all indemnified parties
in connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances. If it so elects within a reasonable time after receipt of such
notice, an indemnifying party, jointly with any other indemnifying parties
receiving such notice, may assume the defense of such action with counsel chosen
by it and reasonably satisfactory to the indemnified parties defendant in such
action, unless such indemnified parties reasonably object to such assumption on
the ground that representation by such counsel would be inappropriate due to
actual or potential differing interests between the indemnified and the
indemnifying parties. If an indemnifying party assumes the defense of such
action, the indemnifying parties shall not be liable for any fees and expenses
of counsel for the indemnified parties incurred thereafter in connection with
such action. No indemnifying party shall, without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 6 or Section 7 hereof (whether or not the indemnified parties
are actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

                  (d) If at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel for which they are entitled to be indemnified hereunder, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 6(a)(ii) effected without its written consent if
(i) such settlement is entered into more than 45 days after

<PAGE>   33
                                       32

receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party for such
fees and expenses of counsel in accordance with such request prior to the date
of such settlement.

                  Section 7. Contribution. If the indemnification provided for
in Section 6 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Initial Purchasers on the other hand from the
offering of the Securities pursuant to this Agreement or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the Company on the one hand and of the
Initial Purchasers on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

                  The relative benefits received by the Company on the one hand
and the Initial Purchasers on the other hand in connection with the offering of
the Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total Initial Purchasers' discount received by the Initial
Purchasers, in each case as set forth on the cover page of the Offering
Memorandum bear to the price to investors appearing thereon.

                  The relative fault of the Company on the one hand and the
Initial Purchasers on the other hand shall be determined by reference to, among
other things, whether any such untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information supplied by the Company or by the Initial Purchasers and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

                  The Company and the Initial Purchasers agree that it would not
be just and equitable if contribution pursuant to this Section 7 were determined
by pro rata allocation (even if the Initial Purchasers were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
7. The aggregate amount of losses, liabilities, claims, damages and

<PAGE>   34
                                       33

expenses incurred by an indemnified party and referred to above in this Section
7 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

                  Notwithstanding the provisions of this Section 7, no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Securities underwritten by it and distributed
to investors were offered to investors exceeds the amount of any damages which
such Initial Purchaser has otherwise been required to pay by reason of any such
untrue or alleged untrue statement or omission or alleged omission.

                  No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

                  For purposes of this Section 7, each person, if any, who
controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act shall have the same rights to contribution as such
Initial Purchaser, and each director of the Company, each officer of the
Company, and each person, if any, who controls the Company within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Company. The Initial Purchasers' respective
obligations to contribute pursuant to this Section 7 are several in proportion
to the number of Initial Securities set forth opposite their respective names in
Schedule I hereto and not joint.

                  Section 8. Representations, Warranties and Agreements to
Survive Delivery. The representations, warranties, indemnities, agreements and
other statements of the Company or its officers set forth in or made pursuant to
this Agreement will remain operative and in full force and effect regardless of
any investigation made by or on behalf of the Company, the Initial Purchasers or
any person who controls the Company or the Initial Purchasers within the meaning
of Section 15 of the 1933 Act and will survive delivery of and payment for the
Securities.

                  Section 9. Termination of Agreement. (a) The Initial
Purchasers may terminate this Agreement, by notice to the Company, at any time
at or prior to the Closing Time (i) if there has been, since the time of
execution of this Agreement or since the respective dates as of which
information is given in the Offering Memorandum, any Material Adverse Change,
whether or not arising in the ordinary course of business, or (ii) if there

<PAGE>   35
                                       34

has occurred any material adverse change in the financial markets in the United
States, Colombia or other international financial markets, any outbreak of
hostilities or escalation thereof or other calamity or crisis or any change or
development involving a prospective change in national or international
political, financial or economic conditions, or in Colombian taxation affecting
the Company or the Securities or the transfer thereof (otherwise than as set
forth in or contemplated by the Offering Memorandum), or currency exchange rates
for the U.S. dollar into the Colombian peso or exchange controls applicable to
the U.S. dollar or the Colombian peso, in each case the effect of which is such
as to make it, in the judgment of the Initial Purchasers, impracticable to
market the Securities or to enforce contracts for the sale of the Securities, or
(iii) if trading in any securities of the Company has been suspended or limited
by the Commission, or if trading generally on either the Colombian Stock
Exchanges, the American Stock Exchange or the New York Stock Exchange or in the
Nasdaq National Market has been suspended or limited, or minimum or maximum
prices for trading have been fixed, or maximum ranges for prices have been
required, by any of said exchanges or by such system or by order of the
Commission, the National Association of Securities Dealers, Inc. or any other
United States or Colombian governmental authority, or (iv) if a banking
moratorium has been declared by either Colombian, United States federal or New
York state authorities.

                  (b) If this Agreement is terminated pursuant to this Section,
such termination shall be without liability of any party to any other party,
except as provided in Section 4 hereof, and provided further that Sections 6 and
7 shall survive such termination and remain in full force and effect.

                  Section 10. Default. If one of the Initial Purchasers shall
fail at the Closing Time to purchase the Securities that it is obligated to
purchase (the "Defaulted Securities"), the non-defaulting Initial Purchaser
shall have the right, within 24 hours thereafter, to make arrangements to
purchase all, but not less than all, of the Defaulted Securities upon the terms
herein set forth; if, however, such non-defaulting Initial Purchaser has not
completed such arrangements within such 24-hour period, then:

                  (a) if the aggregate principal amount of Defaulted Securities
         does not exceed 10% of the aggregate principal amount of the Securities
         to be purchased, the non-defaulting Initial Purchaser shall be
         obligated to purchase the full amount thereof, or

                  (b) if the aggregate principal amount of Defaulted Securities
         exceeds 10% of the aggregate principal amount of the Securities to be
         purchased, this Agreement shall terminate without liability on the part
         of the non-defaulting Initial Purchaser.

<PAGE>   36
                                       35

                  No action taken pursuant to this Section shall relieve any
defaulting Initial Purchaser from liability in respect of its default.

                  In the event of any such default that does not result in a
termination of this Agreement, either the Initial Purchasers or the Company
shall have the right to postpone the Closing Time for a period not exceeding
seven days in order to effect any required changes in the Offering Memorandum or
in any other documents or arrangements. As used herein, the term "Initial
Purchaser" includes any person substituted for an Initial Purchaser under this
Section 10.

hereunder shall be in writing and shall be deemed to have been duly given if

                  Section 12. Parties. This Agreement is made solely for the
benefit of the Initial Purchasers, the Company and, to the extent expressed, any
person who controls the Company or any Initial Purchaser within the meaning of
Section 15 of the 1933 Act, and the directors of the Company, its officers and
their respective executors, administrators, successors and assigns and no other
person shall acquire or have any right under or by virtue of this Agreement. The
term "successors and assigns" shall not include any purchaser, as such
purchaser, from the Initial Purchasers of the Securities.

                  Section 13. Governing Law and Time. This Agreement shall be

Corporation System, 1633 Broadway, New York, New York 10019 (the "Process
Agent") (and any successor entity), as its authorized agent upon which process
may be served in any suit or proceeding arising out of or relating to this
Agreement, the Indenture, the Notes Registration Rights Agreement and the
Warrant Agreement, the Securities and, if issued, the Exchange Notes and the
Warrant Shares that may be instituted in any federal or state court in The City
of New York, Borough of Manhattan, State of New York or brought under federal or
state securities laws, and acknowledges that the Process Agent has accepted such
designation, (ii) submits to the jurisdiction of any such court in any such suit
or proceeding and (iii) agrees that service of process upon the Process Agent
and written notice of said service to the Company in accordance with Section 11
of this Agreement shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding. The Company further agrees to
take any and all action, including the execution and filing of any and all such
documents and instruments, as may be necessary to continue such designation and
appointment of the Process Agent in full force and effect so long as any of the
Securities or Exchange Notes shall be outstanding; provided that the Company may
(and, to the extent the Process Agent ceases to be able to be served on the
basis contemplated herein, shall), by written notice to the Initial Purchasers
in accordance with Section 11 of this Agreement, designate such additional or
alternative agent for service of process under this Section 14 that (i)
maintains an office located in The City of New York, Borough of Manhattan, State
of New York and (ii) is a corporate service company which acts as agent for
service of process for other persons in the ordinary course of its business.
Such written notice shall identify the name of such agent for service of process

foregoing, any suit, action or proceeding based upon this Agreement may be
instituted by any Initial Purchaser in any competent court in Colombia.

                  To the extent that the Company has or hereafter may acquire
any sovereign immunity from jurisdiction of any court or from any legal process
(whether through service of notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, it hereby irrevocably waives such sovereign immunity, to the extent
permitted by law, in respect of its obligations under the above-referenced
documents.

                  Section 15. Judgment Currency. The Company agrees to indemnify
the Initial Purchasers, the officers, directors and agents or the Initial
Purchasers and each person, if any, who controls the Initial Purchasers within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against
any loss incurred by any of them as a result of any judgment or order being
given or made for any amount due to them under this Agreement and such judgment
or order being expressed and paid in a currency (the "Judgment

<PAGE>   38
                                       37

Currency") other than United States dollars and as a result of any variation as
between (i) the rate of exchange at which the United States dollar amount is
converted into the Judgment Currency for the purpose of such judgment or order
and (ii) the spot rate of exchange in The City of New York at which any such
person on the date of payment of such judgment or order is able to purchase
United States dollars with the amount of the Judgment Currency actually received
by such person. The foregoing indemnity shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "spot rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of, or conversion into, United States dollars.

                  Section 16. Withholding Taxes. All amounts payable by the
Company in respect of this Agreement shall be paid in U.S. dollars without
set-off or counterclaim and free and clear of, and without deduction or
withholding for or on account of, any present or future tax, assessment or other
governmental charge or any interest or penalty thereon (collectively, "Tax")
imposed, levied, collected, assessed, or required to be deducted, withheld or
paid by or for the account of Colombia or any taxing authority or political
subdivision thereof or therein. If any such Tax is required by law to be
withheld or deducted from any such payment, the Company shall pay the full
amount of such Tax and pay such additional amounts as may be necessary to ensure
that the net amount actually received by the Initial Purchasers in respect of
such payment is equal to the amount the Initial Purchasers would have received
had no such Tax been withheld or deducted from such payment.

                  Section 17. Counterparts. This Agreement may be executed in
one or more counterparts and when a counterpart has been executed by each party,
all such counterparts taken together shall constitute one and the same
agreement.

our agreement, please sign and return to us a counterpart hereof, whereupon this

Ladies and Gentlemen:

         In connection with our proposed purchase of ___ Units, each consisting
of US$1,000 principal amount of 14% Senior Discount Notes due 2004 (the "Notes")
and four warrants (each a "Warrant") to purchase 5.709 shares of Class B Common
Stock of the Company, with a par value of 1,000 Pesos per share (the "Warrant
Shares"), at a price of US$1.00 per share (or, if greater, the U.S. dollar
equivalent of 1,000 Pesos) either as American Depositary Receipts ("ADRs"; each
ADR representing 25 Warrant Shares) or, if ADRs are not available, such Warrant
Shares of Occidente y Caribe Celular S.A. (the "Issuer"), we confirm that:

         1. We understand that the Units have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), and may not be sold
except as permitted in the following sentence. We agree on our own behalf and on
behalf of any investor account for which we are purchasing Units to offer, sell
or otherwise transfer such Units prior to the date which is three years after
the later of the date of original issue and the last date on which the Issuer or
any affiliate of the Issuer was the owner of such Units (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to the Issuer, (b)
pursuant to a registration statement which has been declared effective under the
Securities Act, (c) for so long as the Units are eligible for resale pursuant to
Rule 144A under the Securities Act, to a person we reasonably believe is a
qualified institutional buyer under Rule 144A (a "QIB") that purchases for its
own account or for the account of a QIB and to whom notice is given that the
transfer is being made in reliance on Rule 144A, (d) pursuant to offers and
sales to non-U.S. persons that occur outside the United States within the
meaning of Regulation S


<PAGE>   42
                                                                             -2-

under the Securities Act, (e) to an institutional "accredited investor" within
the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the
Securities Act that is acquiring the Units for its own account or for the
account of such in institutional "accredited investor" for investment purposes
and not with a view to, or for offer or sale in connection with, any
distribution in violation of the Securities Act or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act,
subject in each of the foregoing cases to any requirement of law that the
disposition of our property or the property of such investor account or accounts
be at all times within our or their control and to compliance with any
applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or
other transfer of the Units is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination, the transferor shall deliver a
letter from the transferee substantially in the form of this letter to the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" within the meaning of subparagraph (a)(1),
(2), (3) or (7) of Rule 501 under the Securities Act and that it is acquiring
such Units for investment purposes and not for distribution in violation of the
Securities Act. We acknowledge that the Issuer and the Trustee reserve the right
prior to any offer, sale or other transfer prior to the Resale Restriction
Termination Date of the Units pursuant to clauses (d), (e) and (f) above to
require the delivery of an opinion of counsel, certifications and/or other
information satisfactory to the Issuer and the Trustee.

         2. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) purchasing
for our own account or for the account of such an institutional "accredited
investor," and we are acquiring the Units for investment purposes and not with a
view to, or for offer or sale in connection with, any distribution in violation
of the Securities Act and we have such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of our
investment in the Units, and we and any accounts for which we are acting are
each able to bear the economic risk of our or its investment.

         3. We are acquiring the Units purchased by us for our own account or
for one or more accounts as to each of which we exercise sole investment
discretion.

authorized to produce this letter or a copy hereof to any interested party in
any administrative or legal proceeding or official inquiry with respect to the

                    4,355,852 Shares of Class B Common Stock

Ladies and Gentlemen:

                  We have acted as United States counsel to Occidente y Caribe
Celular S.A., a sociedad anonima existing under the laws of Colombia (the
"Company"), in connection with the sale by the Company of 190,745 units (the
"Units") consisting of US$190,745,000 aggregate principal amount at maturity of
its 14% Senior Discount Notes due 2004 (the "Notes") and 762,980 warrants (the
"Warrants") entitling the holders thereof to purchase, under certain
circumstances, an aggregate of 4,355,852 shares of class B common stock, par
value one thousand Pesos per share, of the Company (the "Class B Common Stock"),
subject to adjustment (the "Warrant Shares"), to Merrill Lynch, Pierce, Fenner &
Smith Incorporated and ING Baring (U.S.) Securities, Inc. (collectively, the
"Initial Purchasers"), pursuant to the Purchase Agreement dated May 31, 1996
(the "Purchase Agreement") among the Initial Purchasers and the Company. The
Notes, the Warrants and the Units are collectively referred to herein as the

                  In that capacity, we participated in conferences with certain

                  Although we have made certain inquiries and investigations in

except to the extent set forth in paragraphs 1 and 7 in our opinion to you dated
the date hereof. Subject to the foregoing, we hereby advise you that our work in

included therein, as to which we do not express any view), as of its date or as
of the date hereof, included or includes an untrue statement of a material fact

Ladies and Gentlemen:

         I have acted as General Counsel (Secretario General y Vicepresidente
Administrativo) to Occidente y Caribe Celular S.A., a sociedad anonima existing
under the laws of Colombia (the "Company"), in connection with the issuance and
sale by the Company of 190,745 units (the "Units") consisting of US$190,745,000
aggregate principal amount at maturity of its 14% Senior Discount Notes due 2004
(the "Notes") and 762,980 warrants (the "Warrants") entitling the holders
thereof to purchase, under certain circumstances, an aggregate of 4,355,852
shares of class B common stock, par value one thousand Pesos per share, of the
Company (the "Class B Common Stock"), subject to adjustment (the "Warrant
Shares"). The Notes, the Warrants and the Units are collectively referred to
herein as the "Securities." The Notes are to be issued pursuant to an indenture
dated as of June 1, 1996 (the "Indenture") between the Company, as issuer, and
The Bank of New York, as trustee (the "Trustee"). The Warrants are to be issued
pursuant to a warrant agreement dated as of June 7, 1996 (the "Warrant
Agreement") between the Company and The Bank of New York, as warrant agent (the
"Warrant Agent"). This opinion is furnished to you pursuant to Section 5(b) of
the Purchase Agreement dated May 31, 1996 (the "Purchase Agreement") among the
Company, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch")
and ING Baring (U.S.) Securities, Inc. (together with Merrill Lynch, the
"Initial Purchasers") relating to the issuance and sale of the Securities. Terms
defined in the Purchase Agreement and not otherwise defined herein are used
herein with the meanings so defined.

         I have examined originals, or copies certified or otherwise identified
to my satisfaction, of such documents, corporate records and other instruments
as I have deemed necessary or appropriate for the purposes of this opinion,
including (a) the Preliminary


<PAGE>   54
                                       D-2

Offering Memorandum dated May 9, 1996 and the Offering Memorandum dated May 31,
1996, (b) the Purchase Agreement, (c) the Indenture, (d) the Notes Registration
Rights Agreement, (e) the Warrant Agreement and (f) the form of certificates
representing each of the Securities, and I have conducted such other
investigations of fact and law as I have deemed necessary or advisable for
purposes of this opinion. I have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as certified or photostatic copies and the
authenticity of the originals of such latter documents.

         In giving the opinions expressed below I do not express any opinion as
to the laws of any jurisdiction other than the laws of the Republic of Colombia
("Colombia"). The opinions set forth below are based on the laws, rules or
regulations as the case may be, in effect on the date hereof.

         Based upon and subject to the foregoing, I am of the opinion that:

         (i) The Company is a sociedad anonima de economia mixta duly organized
     and existing under the laws of Colombia, with the requisite power and
     authority under such laws to own or hold its properties and to carry on the
     business of providing cellular telecommunications services as described in
     the Offering Memorandum, and the Company does not own or hold any material
     properties or assets other than those incidental to its business.

         (ii) The Company owns or possesses or has obtained all material
     governmental licenses, certificates, permits, consents, orders, approvals
     and other authorizations necessary to hold all concessions, leases and
     permits or own its properties, including the Concession, and to carry on
     its business as presently conducted, and the Company has not received any
     notice relating to the revocation or modification of any such concession,
     license, certificate, permit, consent, order, approval or other
     authorizations.

         (iii) The authorized, issued and outstanding capital stock of the
     Company is as set forth in the capitalization table in the Offering
     Memorandum under the caption "Capitalization." All of the issued and
     outstanding shares of capital stock of the Company have been duly
     authorized and validly issued and are fully paid and nonassessable, the
     shareholders of the Company have no preemptive rights to acquire the
     Warrant Shares that have not been waived and there are no restrictions on
     transfer of any class of the capital stock of the Company, except for the
     right of first refusal as described in the Offering Memorandum.

         (iv) The Company has the requisite corporate capacity and power (A) to
     execute, deliver and perform its obligations under the Purchase Agreement,
     the Indenture, the Notes Registration Rights Agreement and the Warrant
     Agreement, and (B) to issue, deliver and perform its obligations under the
     Notes, the Warrants and the Warrant Shares; each of the Purchase Agreement,
     the Indenture, the Notes Registration Rights Agreement, the Warrant
     Agreement, the Notes and the Warrants has been duly authorized, executed
     and delivered by the Company.


<PAGE>   55
                                       D-3

         (v) To the best of my knowledge, no default exists in the performance
     or observance of any material obligation, agreement, covenant or condition
     contained in any contract, indenture, mortgage, loan agreement, note, lease
     or other agreement or instrument that is not described or referred to in
     the Offering Memorandum.

         (vi) The execution and delivery of the Purchase Agreement, the
     Indenture, the Notes Registration Rights Agreement and the Warrant
     Agreement, the issuance and delivery of the Notes, and, if issued, the
     Exchange Notes, the Warrants and, assuming the Company obtains the
     corporate and governmental approvals as set forth in the Offering
     Memorandum, the Warrant Shares, the consummation by the Company of the
     transactions contemplated therein and compliance by the Company with the
     terms thereof do not and will not result in any violation of the estatutos
     sociales of the Company, and do not and will not conflict with, or result
     in a breach of any of the terms or provisions of, or constitute a default
     under, or result in the creation or imposition of any lien, charge or
     encumbrance upon any property or assets of the Company under (A) any
     contract, indenture, mortgage, loan agreement, note, lease or any other
     agreement or instrument to which the Company is a party or by which it may
     be bound or to which any of its properties may be subject (except for such
     conflicts, breaches or defaults or liens, charges or encumbrances that in
     the aggregate, would not have a material adverse change in the condition
     (financial or otherwise), earnings, business affairs or business prospects
     of the Company), or (B) any judgment, order or decree of any government,
     governmental instrumentality, court or arbitrator, domestic or foreign,
     having jurisdiction over the Company or any of its respective properties
     (except as otherwise disclosed in the Offering Memorandum and except for
     such violations that in the aggregate would not have a material adverse
     change in the condition (financial or otherwise), earnings, business
     affairs or business prospects of the Company).

         (vii) There is no action, suit, proceeding, inquiry or investigation,
     pending, or to the best of my knowledge, threatened, other than as set
     forth in the Offering Memorandum to which the Company is a party, or to
     which the property of the Company is subject, before or brought by any
     court or governmental agency or body, domestic or foreign, which is likely
     to have a material adverse effect on the condition (financial or
     otherwise), earnings, business affairs or business prospects of the Company
     or which might reasonably be expected to materially and adversely affect
     the consummation of the Purchase Agreement, the Indenture, the Notes
     Registration Rights Agreement or the Warrant Agreement, or the performance
     by the Company of its obligations thereunder.

         I have participated in the preparation of the Offering Memorandum. In
the course of the preparation by the Company of the Offering Memorandum, I have
participated in discussions with your representatives and those of the Company
and its independent accountants, in which the business and affairs of the
Company and the contents of the Offering Memorandum were discussed. Nothing has
come to my attention that would lead me to believe that the Offering Memorandum
(except for Annex C thereof and the financial statements and other information
of an accounting or financial nature included therein, as to which I do not
express any view), as of its date or as of the date hereof, included or includes
an untrue statement of a material fact or omitted or omits to state a material
fact necessary in

order to make the statements therein, in the light of the circumstances under
which they were made, not misleading.

         I am an attorney admitted to practice in Colombia and I do not express
any opinion as to the laws of any other jurisdiction other than the laws of
Colombia. In particular, I do not purport to pass on any matter governed by the
laws of the State of New York and the federal law of the United States. I
understand that with regard to matters governed by the laws of the State of New
York and the federal law of the United States you are being provided with the
opinions of Cravath, Swaine & Moore, United States counsel to the Company,
delivered pursuant to Section 5(a) of the Purchase Agreement.

         Except as otherwise provided in the following sentence, this opinion is
being furnished only to you and is solely for your benefit in connection with
the above transaction and may not be relied upon for any other purpose or
furnished, used, circulated, quoted or otherwise referred to for any other
purpose without my prior written consent. This opinion may be delivered to
Cravath, Swaine & Moore, United States counsel to the Company, Holguin, Neira y
Pombo, special Colombian counsel to the Company and to The Bank of New York, as
Trustee under the Indenture and as Warrant Agent under the Warrant Agreement,
and each of them may rely on this opinion to the same extent as if such opinion
were addressed to them.

                                                     Very truly yours,

par value one thousand Pesos per share, of the Company (the "Class B Common
Stock"), subject to adjustment (the "Warrant Shares"). The Notes, the Warrants
and the Units are collectively referred to herein as the "Securities." The Notes
are to be issued pursuant to an indenture dated as of June 1, 1996 (the
"Indenture") between the Company, as issuer, and The Bank of New York, as
trustee (the "Trustee"). The Warrants are to be issued pursuant to a warrant
agreement dated as of June 7, 1996 (the "Warrant Agreement") between the Company
and The Bank of New York, as warrant agent (the "Warrant Agent"). This opinion
is furnished to you pursuant to Section 5(c) of the Purchase Agreement dated May
31, 1996 (the "Purchase Agreement") among the Company, Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("Merrill Lynch") and ING Baring (U.S.) Securities,
Inc. (together with Merrill Lynch, the "Initial Purchasers") relating to the
issuance and sale of the Securities. Terms defined in the Purchase Agreement and
not otherwise defined herein are used herein with the meanings so defined.

         In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary or appropriate for the
purposes of this opinion, including (a) the

                                       E-2

Preliminary Offering Memorandum dated May 9, 1996 and the Offering Memorandum
dated May 31, 1996, (b) the Purchase Agreement, (c) the Indenture, (d) the Notes
Registration Rights Agreement, (e) the Warrant Agreement and (f) the form of
certificates representing each of the Securities, and we have conducted such
other investigations of fact and law as we have deemed necessary or advisable
for purposes of this opinion. We have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such latter documents.

         In giving the opinions expressed below we do not express any opinion as
to the laws of any jurisdiction other than the laws of the Republic of Colombia
("Colombia"). The opinions set forth below are based on the laws, rules or
regulations as the case may be, in effect on the date hereof.

         Based upon and subject to the foregoing, we are of the opinion that:

         (i) The Company is a sociedad anonima duly organized and existing under
     the laws of Colombia, with the requisite power and authority under such
     laws to own or hold its properties and to carry on the business of
     providing cellular telecommunications services as described in the Offering
     Memorandum.

         (ii) The Company owns or possesses or has obtained all material
     governmental licenses, certificates, permits, consents, orders, approvals
     and other authorizations necessary to hold all concessions, leases and
     permits or own its properties, including the Concession, and to carry on
     its business as presently conducted, and, to the best of our knowledge
     after due inquiry, the Company has not received any notice relating to the
     revocation or modification of any such concession, license, certificate,
     permit, consent, order, approval or other authorizations.

         (iii) The authorized, issued and outstanding capital stock of the
     Company is as set forth in the capitalization table in the Offering
     Memorandum under the caption "Capitalization." All of the issued and
     outstanding shares of capital stock of the Company have been duly
     authorized and validly issued and are fully paid and nonassessable, the
     shareholders of the Company have no preemptive rights to acquire the
     Warrant Shares that have not been waived and there are no restrictions on
     transfer of any class of the capital stock of the Company, except for the
     right of first refusal as described in the Offering Memorandum.

         (iv) The Company has the requisite corporate capacity and power (A) to
     execute, deliver and perform its obligations under the Purchase Agreement,
     the Indenture, the Notes Registration Rights Agreement and the Warrant
     Agreement, and (B) to issue, deliver and perform its obligations under the
     Notes, the Warrants and the Warrant Shares; each of the Purchase Agreement,
     the Indenture, the Notes Registration Rights Agreement, the Warrant
     Agreement, the Notes and the Warrants has been duly authorized, executed
     and delivered by the Company.


<PAGE>   59
                                       E-3

         (v) The form of certificates representing each of the Notes and the
     Warrants complies with the provisions of the Colombian law relating
     thereto.

         (vi) The information in the Offering Memorandum with respect to or
     involving matters of Colombian law, including the information under the
     captions "Enforceability of Civil Liabilities," "Business -- Legal
     Proceedings," "Regulation," "Description of the Notes," "Description of the
     Warrants," "Description of the Units," "Description of Capital Stock,"
     "Description of American Depositary Receipts," "Foreign Investment and
     Exchange Controls in Colombia," "Enforcement of Foreign Judgments in
     Colombia" and "Taxation -- Colombia," to the extent that it constitutes
     matters of law, summaries of legal matters, the Company's estatutos
     sociales or legal proceedings, or legal conclusions, has been reviewed by
     us and is correct in all material respects.

         (vii) To the best of our knowledge, no default exists in the
     performance or observance of any material obligation, agreement, covenant
     or condition contained in any contract, indenture, mortgage, loan
     agreement, note, lease or other agreement or instrument that is not
     described or referred to in the Offering Memorandum.

         (viii) The execution and delivery of the Purchase Agreement, the
     Indenture, the Notes Registration Rights Agreement and the Warrant
     Agreement, the issuance and delivery of the Notes, and, if issued, the
     Exchange Notes, the Warrants and, assuming the Company obtains the
     corporate and governmental approvals as set forth in the Offering
     Memorandum, the Warrant Shares, the consummation by the Company of the
     transactions contemplated therein and compliance by the Company with the
     terms thereof do not and will not result in any violation of the estatutos
     sociales of the Company, and do not and will not conflict with, or result
     in a breach of any of the terms or provisions of, or constitute a default
     under, or result in the creation or imposition of any lien, charge or
     encumbrance upon any property or assets of the Company under (A) any
     contract, indenture, mortgage, loan agreement, note, lease or any other
     agreement or instrument to which the Company is a party or by which it may
     be bound or to which any of its properties may be subject (except for such
     conflicts, breaches or defaults or liens, charges or encumbrances that in
     the aggregate, would not have a material adverse change in the condition
     (financial or otherwise), earnings, business affairs or business prospects
     of the Company), or (B) any existing, applicable law, rule or regulation,
     or any judgment, order or decree of any government, governmental
     instrumentality, court or arbitrator, domestic or foreign, having
     jurisdiction over the Company or any of its respective properties (except
     as otherwise disclosed in the Offering Memorandum and except for such
     violations that would not have a material adverse change in the condition
     (financial or otherwise), earnings, business affairs or business prospects
     of the Company).

         (ix) No authorization, approval, consent, license, exemption, order or
     decree of any Colombian government, governmental instrumentality, court or
     arbitrator (A) is required for the execution, delivery and performance by
     the Company of each of the Purchase Agreement, the Indenture, the Notes
     Registration Rights Agreement and the Warrant Agreement including for the
     valid authorization, issuance, sale and delivery of the Notes and the
     Exchange Notes under the Indenture or the Warrants and the Warrant Shares
     under the Warrant Agreement, or (B) is required to permit the Company to
     effect


<PAGE>   60
                                       E-4

     payments of principal of, premium and interest on the Notes, and, if
     issued, the Exchange Notes, and the performance of its other obligations
     under the Indenture in United States dollars, except for the approvals from
     (i) the Ministry of Communications with respect to the exercise of the
     Warrants, (ii) the Colombian Superintendency of Securities as to the ADRs,
     (iii) the corporate and governmental approvals or actions necessary for the
     issuance of the ADRs and Warrant Shares as described in the Offering
     Memorandum and (iv) the registration of an official translation of the
     Indenture (which shall be signed before a notary public and consularized)
     and the Notes with Banco de la Republica, and except for such other
     authorizations, approvals, consents, licenses, exemptions, orders or
     decrees (including the authorization of the Colombian Superintendency of
     Corporations and the registration of the terms of the Notes and the Notes
     with Banco de la Republica) which have been obtained and are in full force
     and effect.

         (x) There is no action, suit, proceeding, inquiry or investigation,
     pending, or to the best of our knowledge, threatened, other than as set
     forth in the Offering Memorandum to which the Company is a party, or to
     which the property of the Company is subject, before or brought by any
     court or governmental agency or body, domestic or foreign, which is likely
     to have a material adverse effect on the condition (financial or
     otherwise), earnings, business affairs or business prospects of the Company
     or which might reasonably be expected to materially and adversely affect
     the consummation of the Purchase Agreement, the Indenture, the Notes
     Registration Rights Agreement or the Warrant Agreement, or the performance
     by the Company of its obligations thereunder.

         (xi) The governing law clauses subjecting the Purchase Agreement, the
     Indenture, the Notes Registration Rights Agreement, the Warrant Agreement,
     the Warrants and the Notes to New York law are valid under Colombian law.

         (xii) Each of the Purchase Agreement, the Indenture, the Notes
     Registration Rights Agreement, the Warrant Agreement, the Warrants and the
     Notes are in proper legal form under the laws of Colombia for the
     enforcement thereof against the Company in the courts of Colombia (provided
     that an official Spanish translation of each such document is required to
     bring an action thereon in the courts of Colombia and the registrations
     listed in paragraph (xix) below shall have been made).

         (xiii) In any action or proceeding arising out of or relating to any of
     the Purchase Agreement, the Indenture, the Notes Registration Rights
     Agreement, the Warrant Agreement, the Notes or the Warrants in any court in
     Colombia, such court would recognize and give effect to the provisions of
     such agreement or security wherein the parties thereto agree that the
     Purchase Agreement, the Indenture, the Notes Registration Rights Agreement,
     the Warrant Agreement, the Notes and the Warrants shall be governed by, and
     construed in accordance with, the provisions of New York law, provided that
     neither the terms of any such agreement or security nor any provisions of
     New York law applicable to any such agreement or security are found to be
     contrary to the public policy (orden publico) of Colombia.


<PAGE>   61
                                       E-5

         (xiv) In our opinion, none of the terms of the Purchase Agreement, the
     Indenture, the Notes Registration Rights Agreement or the Warrant
     Agreement, the Warrants, the Notes or if issued, the Exchange Notes, are
     contrary to the public policy (orden publico) of Colombia except that
     indemnification provisions might be subject to certain limitations.

         (xv) Any judgment against the Company of a court in the State of New
     York or of a federal court of the United States of America, in each case
     sitting in the Borough of Manhattan, The City of New York, which is
     obtained without fraud and rendered after due notice by any such state or
     federal court, is capable of being enforced in the courts of Colombia upon
     compliance with the requisites and procedures set forth in the Colombian
     Civil Procedure Code (including, in the case of such judgment, articles
     693, 694 and 695 of the Colombian Civil Procedure Code, which apply in
     order to obtain an exequator from the Supreme Court of Justice of
     Colombia).

         (xvi) The submission of the Company to the jurisdiction of the courts
     of the State of New York and of the federal courts of the United States of
     America, in each case sitting in the Borough of Manhattan, The City of New
     York, and the appointment of the agent for service of process, contained in
     the Purchase Agreement, the Indenture, the Notes Registration Rights
     Agreement and the Warrant Agreement is valid.

         (xvii) Neither the Company nor any of its properties or assets has any
     sovereign immunity from the jurisdiction of any court or from any legal
     process (whether through service or notice, attachment prior to judgment,
     attachment in aid of execution, execution or otherwise) under the laws of
     Colombia.

         (xviii) Except as otherwise described in the Offering Memorandum, there
     is no tax, duty, levy, impost, deduction, charge or withholding imposed by
     Colombia or any political subdivision thereof or taxing authority therein
     or any federation or organization or similar entity of which Colombia is a
     member either (A) on or by virtue of the Company's execution, delivery,
     performance or enforcement of the Purchase Agreement, the Indenture, the
     Notes Registration Rights Agreement, the Warrant Agreement, or of any other
     document to be furnished hereunder or thereunder, or (B) on any payment to
     be made pursuant to the Purchase Agreement, the Indenture, the Notes
     Registration Rights Agreement or the Warrant Agreement, except that
     withholding taxes are payable on the "Cash Election Warrant Repurchase" (as
     defined in Section 3.1 of the Warrant Agreement) and may be payable on the
     fees and expenses of the Trustee and the Warrant Agent. Under current
     Colombian law and regulations, payments on the Notes to nonColombian
     residents are not and will not be subject to any Colombian withholding or
     any other tax, except as otherwise described in the Offering Memorandum.

         (xix) To ensure the legality, validity, enforcement or admissibility
     into evidence in Colombia of the Purchase Agreement, the Indenture, the
     Notes Registration Rights Agreement, the Warrant Agreement, the Warrants or
     the Notes and any other document to be furnished thereunder, it is not
     necessary that the Purchase Agreement, the Indenture, the Notes
     Registration Rights Agreement, the Warrant Agreement, the Warrants or the
     Notes or any such other document be filed, recorded or registered with any
     court or other authority in Colombia, except (a) the registration of an
     official


<PAGE>   62
                                       E-6

     translation of the Indenture (which shall be signed before a notary public
     and consularized) and the Notes with Banco de la Republica and (b) the
     registration of the terms of the Notes and the Notes with Banco de la
     Republica, which registration has been duly obtained, or that any tax be
     paid in Colombia on or in respect of any of the Purchase Agreement, the
     Indenture, the Notes Registration Rights Agreement, the Warrant Agreement,
     or any such other document.

         (xx) Except as described in the Offering Memorandum, non-Colombian
     holders of Notes or Warrants will not be deemed resident, domiciled,
     carrying on business or subject to taxation in Colombia solely by reason of
     the execution, delivery, performance or enforcement of the Purchase
     Agreement, the Indenture, the Notes Registration Rights Agreement or the
     Warrant Agreement. Non-Colombian holders of the Warrant Shares will be
     subject to Colombian taxes and Colombian foreign investment registration
     and regulations, as described in the Offering Memorandum.

         (xxi) Except as described in the Offering Memorandum, it is not
     necessary under the laws of Colombia that any of the holders of the
     Securities be licensed, qualified or entitled to carry on business in
     Colombia by reason solely of the execution, delivery, performance or
     enforcement of this Agreement, the Indenture, the Notes Registration Rights
     Agreement or the Warrant Agreement.

         We have participated in the preparation of the Offering Memorandum. In
the course of the preparation by the Company of the Offering Memorandum, we have
participated in discussions with your representatives and those of the Company
and its independent accountants, in which the business and affairs of the
Company and the contents of the Offering Memorandum were discussed. Nothing has
come to our attention that would lead us to believe that the Offering Memorandum
(except for Annex C thereof and the financial statements and other information
of an accounting or financial nature included therein, as to which we do not
express any view), as of its date or as of the date hereof, included or includes
an untrue statement of a material fact or omitted or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

         We are attorneys admitted to practice in Colombia and we do not express
any opinion as to the laws of any other jurisdiction other than the laws of
Colombia. In particular, we do not purport to pass on any matter governed by the
laws of the State of New York and the federal law of the United States. We
understand that with regard to matters governed by the laws of the State of New
York and the federal law of the United States you are being provided with the
opinions of Cravath, Swaine & Moore, United States counsel to the Company,
delivered pursuant to Section 5(a) of the Purchase Agreement. Furthermore, we
rely, insofar as this opinion involves matters of fact (but not as to legal
conclusions), to the extent we deem proper, on information or certificates
received from responsible officers of the Company and public officials.

         We note that, as disclosed in the Offering Memorandum, a member of
Holguin Neira y Pombo is an alternate director of the Company.

Ladies and Gentlemen:

         We have acted as United States counsel to The Bank of New York, a New
York banking corporation, in connection with (i) its execution and delivery of
the Indenture dated as of June 1, 1996 (the "Indenture") by and between
Occidente y Caribe Celular S.A. (the "Company") and The Bank of New York, as
trustee (the "Trustee"), pursuant to which the Company is issuing on the date
hereof US$ 190,745,000 in aggregate principal amount at maturity of its 14%
Senior Discount Notes due 2004 (the "Notes"); (ii) its authentication and
delivery of the Notes in global and certificated form; and (iii) its execution
and delivery of a Warrant Agreement dated as of June 7, 1996 (the "Warrant
Agreement") by and between the Company and The Bank of New York, as Warrant
Agent, providing for the issuance by the Company of 762,980 warrants in global
and certificated form (the "Warrants") entitling the holders thereof to
purchase, under certain circumstances, an aggregate of 4,355,852 shares of class
B common stock, par value one thousand Pesos per share, of the Company (the
"Class B Common Stock"), subject to adjustment (the "Warrant Shares"), either as
(i) American Depositary Receipts (ADRs) or (ii) if ADRs are not available, such
Warrant Shares.

         In acting as such United States counsel, we have examined executed
copies of the Indenture, the global and certificated Notes, the Warrant
Agreement and the global and certificated Warrants. As to any facts material to
our opinions expressed herein, we have relied upon the representations and
warranties contained in the documents referred to above


<PAGE>   65
                                       F-2

and originals, or copies identified to our satisfaction, of such corporate
records of The Bank of New York and such agreements, certificates of responsible
officers of The Bank of New York and public officials, powers of attorney,
governmental orders and other documents as we have deemed necessary or
appropriate as a basis for the opinions hereinafter expressed. In such
examination, we have assumed the legal capacity of all natural persons, the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all documents submitted to
us as certified or photostatic copies and the authenticity of the originals of
such latter documents.

         We have assumed the due execution and delivery, pursuant to due
authorization, of the Indenture and the Warrant Agreement by the Company. We
have also assumed that the execution, delivery and performance by each of the
parties to each of the Indenture and the Warrant Agreement will not violate, or
be inconsistent with, any applicable law other than, but only insofar as it
relates to The Bank of New York, the law of the State of New York or the federal
law of the United States.

         Based upon and subject to the foregoing, we are of the opinion that:

         (i) The Indenture has been duly authorized, executed and delivered by
     The Bank of New York, as Trustee, and, assuming that the Indenture
     constitutes a valid and binding obligation of each of the other parties
     thereto enforceable against each of them in accordance with its terms,
     constitutes the valid and binding obligation of The Bank of New York, as
     Trustee, enforceable against it in accordance with its terms, except as
     enforceability may be limited by bankruptcy, insolvency (including, without
     limitation, all laws relating to fraudulent transfers), reorganization,
     moratorium or other similar laws affecting creditors' rights generally and
     except as enforcement thereof is subject to general principles of equity
     (regardless of whether enforcement is considered in a proceeding in equity
     or at law).

         (ii) Assuming due authorization, execution and delivery of the Notes by
     the Company, the Notes have been duly authenticated and delivered by The
     Bank of New York, as Trustee.

         (iii) The Warrant Agreement has been duly authorized, executed and
     delivered by The Bank of New York, as Warrant Agent, and, assuming that the
     Warrant Agreement constitutes a valid and binding obligation of each of the
     other parties thereto enforceable against each of them in accordance with
     its terms, constitutes the valid and binding obligation of The Bank of New
     York, as Warrant Agent, enforceable against it in accordance with its
     terms, except as enforceability may be limited by bankruptcy, insolvency
     (including, without limitation, all laws relating to fraudulent transfers),
     reorganization, moratorium or other similar laws affecting creditors'
     rights generally and except as enforcement thereof is subject to general
     principles of equity (regardless of whether enforcement is considered in a
     proceeding in equity or at law).


<PAGE>   66
                                       F-3

         (iv) Assuming due authorization, execution and delivery of the Warrants
     by the Company, the Warrants have been duly countersigned and delivered by
     The Bank of New York, as Warrant Agent.

         We are attorneys admitted to practice in the State of New York and we
do not express any opinion as to the laws of any other jurisdiction other than
the laws of the State of New York and the federal law of the United States of
America.

         This opinion is being furnished only to you and is solely for your
benefit in connection with the above transaction and may not be relied upon for
any other purpose or furnished, used, circulated, quoted or otherwise referred
to for any other purpose without our prior written consent.

set forth herein, each Lender severally agrees on the Borrowing Date to make a
loan to the Borrower on or prior to the Commitment Termination Date (each a
"Loan" and collectively, the "Loans"), which Loans shall be in the aggregate
amount of U.S.$80,000,000 and shall be for each Lender that amount which equals

                                      -16-
<PAGE>   22
than one Business Day prior to the Borrowing Date) give each Lender notice of

matters required by the immediately preceding sentences to be specified in the
Notice of Borrowing.

                  2.3 Disbursement of Funds. Subject to the terms and conditions

Lender will make available, through such Lender's Lending Office, its pro rata
portion of the aggregate amount of the Loans to be made on the Borrowing Date,
in Dollars and in immediately available funds at the Payment Office of the
Administrative Agents, and the Administrative Agents will transfer the aggregate
of the amounts so made available by the Lenders, net of fees and costs payable
to the Lenders, in accordance with Schedule VI hereto. Immediately upon receipt
by the Administrative Agents of a Lender's notification of its intention not to
make available the portion of its Commitment, the Administrative Agents shall
notify the Arrangers which shall then make available such amount to the
Administrative Agents on the Borrowing Date in accordance with the preceding
sentence. Unless the Administrative Agents shall have been notified by any
Lender prior to such Borrowing Date that such Lender does not intend to make
available to the Administrative Agents such Lender's portion of the Borrowing to
be made on the Borrowing Date, the Administrative Agents may assume that such
Lender has made such amount available to the Administrative Agents on the

to), in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such corresponding amount is not in fact made available
to the Administrative Agents by such Lender, the Administrative Agents shall be
entitled to recover such corresponding amount from such Lender on demand. If
such Lender does not pay such corresponding amount forthwith upon the
Administrative Agents' demand therefor, the Administrative Agents shall promptly
notify the Arrangers, and the Arrangers shall immediately pay such corresponding
amount to the Administrative Agents. The Administrative Agents shall also be
entitled to recover on demand from such Lender or the Arrangers, as the case may
be, interest on such corresponding amount in respect of each day from the date
such corresponding amount was made available by the Administrative Agents to the
Borrower until the date such corresponding amount is recovered by the
Administrative Agents, at a rate per annum equal to the cost to the
Administrative Agents of acquiring overnight federal funds at the then
applicable rate for the Loans. Nothing in this

                                      -17-
<PAGE>   23
Section 2.3 shall be deemed to relieve any Lender from its obligation to make a
Loan hereunder or to prejudice any rights which the Borrower and the Arrangers
may have against any Lender as a result of any failure by such Lender to make a
Loan hereunder.

                  2.4 Notes. The Borrower's obligation to pay the principal of,
and interest on, each Loan shall be evidenced by a promissory note duly executed
and delivered by the Borrower substantially in the form of Exhibit B hereto
(each, a "Note," and collectively, the "Notes") with blanks appropriately
completed in conformity herewith. Each of the Notes shall (i) be payable to the
order of the Lender making the Loan and be dated the Borrowing Date, (ii) be in
a stated principal amount equal to the Loan evidenced thereby, (iii) mature on
the Maturity Date, (iv) bear interest as provided in Section 2.6 and (v) be
entitled to the benefits of this Agreement and the other Credit Documents.

                  2.5 Pro Rata Borrowing. All Borrowings of Loans under this
Agreement shall be incurred from the Lenders pro rata on the basis of their
Commitments, but shall be undertaken by the Arrangers in any amount that the
Lenders fail to provide. It is understood that no Lender shall be responsible
for any default by any other Lender of its obligation to make a Loan hereunder
and that each Lender shall be obligated to make the Loan provided to be made by
it hereunder regardless of the failure of any other Lender to make its Loan
hereunder.

                  2.6 Interest. (a) The Borrower agrees to pay interest in
respect of the unpaid principal amount of each Loan from the date the proceeds
made thereof are made available to the Borrower until the maturity thereof
(whether by acceleration or otherwise) at a rate per annum which shall, during
each Interest Period applicable thereto, be equal to the sum of the Applicable
Margin (as defined below) plus the Eurodollar Rate for such Interest Period. The
"Applicable Margin" shall be 3.75% per annum; provided, however, that the
Applicable Margin shall be adjusted on any Determination Date, which adjusted
Applicable Margin shall remain in effect until adjusted on any subsequent
Determination Date in accordance with the following:

                (i) if the Debt Ratio as of any Determination Date is 5.00 or
         greater, then the Applicable Margin shall be 3.75% per annum;

                                      -18-
<PAGE>   24
               (ii) if the Debt Ratio as of any Determination Date is less than
         5.00 but not less than 3.80, then the Applicable Margin shall be 3.50%
         per annum;

              (iii) if the Debt Ratio as of any Determination Date is less than
         3.80 but not less than 3.10, then the Applicable Margin shall be 3.25%
         per annum;

               (iv) if the Debt Ratio as of any Determination Date is less than
         3.10 but not less than 2.775, then the Applicable Margin shall be 3.00%
         per annum; and

                (v) if the Debt Ratio as of any Determination Date is less than
         2.775, then the Applicable Margin shall be 2.75% per annum;

provided, further, that the Applicable Margin shall be 2.75% per annum with
respect to a portion of the unpaid principal amount of the Loans (pro rata among
the Lenders in proportion to the principal amount of their respective Loans)
equal to the amount, if any, of U.S. dollars deposited by the Borrower with the
Collateral Agent pursuant to, and in accordance with, Sections 4.2(b) and 4.2(c)
hereof (it being understood that no such adjustment in the Applicable Margin
shall be made under this subparagraph in respect of any deposits of Pesos
pursuant to Section 5.3 of the Disbursement Agreement).

                  (b) Overdue principal and, to the extent permitted by Law,
overdue interest in respect of each Loan and any other overdue amount payable by
the Borrower hereunder or under any other Credit Document shall bear interest at
a rate per annum equal to the rate which is 2.0% in excess of the rate then
borne by such Loans, or, if for any reason the Loans do not have an interest
rate otherwise applicable to them, then at a rate per annum equal to 2.0% per
annum in excess of the Base Rate plus the Applicable Margin, in each such case
accruing from the date on which such principal and interest was due, with such
overdue principal and interest payable on demand.

                  (c) Accrued (and theretofore unpaid) interest shall be payable
in respect of each Loan (i) quarterly in arrears on each September 7, December
7, March 7 and June 7, and (ii) on any repayment, whether mandatory or otherwise
(on the amount repaid), at maturity (whether by acceleration or otherwise) and,
after such maturity, on demand.

                                      -19-
<PAGE>   25
                  (d) On each Interest Determination Date, the Administrative
Agents shall determine the Eurodollar Rate for the Interest Period applicable to
the Loans and shall promptly notify the Borrower and the Lenders thereof. Each
such determination shall, absent manifest error, be final and conclusive and
binding on all parties hereto.

                  2.7 Increased Costs, Illegality, etc. (a) In the event that
any Lender shall have determined (which determination shall, absent manifest
error, be final and conclusive and binding upon all parties hereto but, with
respect to clause (i) below, may be made only by the Administrative Agents):

                (i) on any Interest Determination Date that, by reason of any
         changes arising after the Effective Date affecting the interbank
         Eurodollar market, adequate and fair means do not exist for
         ascertaining the applicable interest rate on the basis provided for in
         the definition of Eurodollar Rate; or

               (ii) at any time, that such Lender shall incur increased costs or
         reductions in the amounts received or receivable hereunder with respect
         to any Loan because of (x) any change since the Effective Date in any
         applicable Law or in the interpretation or administration thereof and
         including the introduction of any new Law, such as, for example, but
         not limited to: (A) a change in the basis of taxation of payments to
         any Lender of the principal of or interest on the Notes or any other
         amounts payable hereunder (except for (i) changes in respect of taxes
         imposed on overall net income pursuant to the Laws of the jurisdiction
         in which the Lender is organized or in which its principal office or
         applicable lending office is located or any subdivision thereof or
         therein, and (ii) any Taxes described in Section 4.4) or (B) a change
         in official reserve requirements and/or (y) other circumstances since
         the Effective Date affecting such Lender or the interbank Eurodollar
         market or the position of such Lender in such market; or

              (iii) at any time, that the making or continuance of any Loan has
         been made (x) unlawful by any Law or (y) impossible by compliance by
         any Lender in good faith with any Law;

then, and in any such event, such Lender (or the Administrative Agents, in the
case of clause (i) above) shall

                                      -20-

<PAGE>   26
promptly give telephonic notice (confirmed in writing) to the Borrower and,
except in the case of clause (i) above, to the Administrative Agents of such
determination (which notice the Administrative Agents shall promptly transmit to
each of the other Lenders). Thereafter (x) in the case of clause (i) above, the
interest rate during the applicable Interest Period shall be the Base Rate in
effect on the applicable Interest Determination Date plus the Applicable Margin,
(y) in the case of clause (ii) above, if the Borrower does not elect to prepay
the Loan or is otherwise unable to prepay the Loan pursuant to applicable Law
subject to such increased costs or reductions within 30 days after receipt of
notice thereof or if later, the last day of the Interest Period during which
such notice is received, in accordance with Section 4.2 hereof, the Borrower
shall pay to such Lender, upon written demand therefor (and against a
certificate specifying in reasonable detail the nature of the increased cost or
reduction, the date from which it has been applied and the method of calculating
such increased cost), such additional amounts (in the form of an increased rate
of, or a different method of calculating, interest) as shall be required to
compensate such Lender for such increased costs or reductions in amounts
received or receivable hereunder (a written notice as to the additional amounts
owed to such Lender, showing the basis for the calculation thereof, submitted to
the Borrower by such Lender shall, absent manifest error, be final and
conclusive and binding on all the parties hereto) and (z) in the case of clause
(iii) above, the Borrower shall repay the Loan of the affected Lender(s) in
accordance with Section 2.7(b) as promptly as possible and, in any event, within
the time period required by Law.

              (b) At any time that any Loan is affected by the circumstances
described in Section 2.7(a)(ii) or (iii), the Borrower may (and in the case of a
Loan affected by the circumstances described in Section 2.7(a)(iii) shall) if
the affected Loan is then outstanding, upon at least five Business Days' written
notice to the Administrative Agents, repay the Loan of the affected Lender(s)
(in which case the Borrower shall have no obligation to pay any additional
amounts pursuant to Section 2.7(a)(i), 2.7(a)(ii) or 2.7(a)(iii), as the case
may be), provided that, if more than one Lender is affected at any time, then
all affected Lenders must be treated the same pursuant to this Section 2.7(b).

              (c) If any Lender determines at any time that the introduction or
implementation of, or any change in, any Law after the Effective Date concerning
capital adequacy, or any change in interpretation or administration thereof by
any

                                      -21-
<PAGE>   27
governmental authority, central bank or comparable agency, will have the effect
of increasing the amount of capital required or expected to be maintained by
such Lender based on the existence of such Lender's Commitment hereunder or its
obligations hereunder, then the Borrower shall pay to such Lender, within 15
Business Days of its written demand therefor, such additional amounts as shall
be required to compensate such Lender for the increased cost to such Lender as a
result of such increase of capital. In determining such additional amounts, each
Lender will act in a commercially reasonable manner and in good faith and will
use averaging and attribution methods which are reasonable, and such Lender's
determination of compensation owing under this Section 2.7 shall, absent
manifest error or a lack of commercial reasonableness or good faith, be final
and conclusive and binding on all the parties hereto. Each Lender, upon
determining that any additional amounts will be payable pursuant to this Section
2.7, will give prompt written notice thereof to the Borrower, which notice shall
show the basis for calculation of such additional amounts, and the failure to
give any such notice shall not release Borrower's obligations to pay additional
amounts pursuant to this Section 2.7 (unless the relevant Lender failed to give
such notice within 90 days of the occurrence of the events which gave the
relevant Lender the right to demand that the Borrower pay additional amounts
pursuant to this Section 2.7, in which case the Borrower shall have no
obligation to pay such additional amounts).

              2.8 Compensation. The Borrower shall compensate each Lender, upon
its written request (which request shall set forth the basis for requesting such
compensation and shall, absent manifest error, be final and conclusive and
binding on all the parties hereto), for all reasonable losses, expenses and
liabilities (including, without limitation, any loss, expense or liability
incurred by reason of the liquidation or reemployment of deposits or other funds
required by such Lender to fund its Loans) which such Lender may sustain: (i) if
for any reason (other than a default by such Lender or the Administrative Agents
or the occurrence of a force majeure event) the Borrowing of Loans does not
occur on the date specified therefor in the Notice of Borrowing (whether or not
withdrawn by the Borrower); or (ii) if any repayment (including any repayment
made pursuant to Sections 4.1 and 4.2 or a result of an acceleration of the
Loans pursuant to Section 9) of its Loans occurs on a date which is not the last
day of an Interest Period with respect thereto.

                                      -22-
<PAGE>   28
              2.9 Change of Lending Office. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of Section 2.7(a)(ii) or
(iii), 2.7(c) or 4.4 with respect to such Lender and prior to delivery of the
notice referred to in Section 2.7 or 4.4, it will use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
designate a different Lending Office if the making of such a designation would
avoid the need for, or reduce the amount of, such increased cost (or increase in
capital) and would not, in the reasonable judgment of such Lender, be otherwise
disadvantageous to such Lender. Nothing in this Section 2.9 shall affect or
postpone any of the obligations of the Borrower or the right of any Lender
provided in Section 2.7 or 4.4.

              2.10 Interest Periods. At the time it gives any Notice of
Borrowing in respect of the Loans in the case of the initial Interest Period or
on the third Business Day prior to the expiration of any subsequent Interest
Period, the Borrower shall have the right to elect, by giving the Administrative
Agent notice thereof, the interest period (each an "Interest Period") applicable
to the Loans, which Interest Period shall, at the option of the Borrower be a
three or six month period, provided that: (a) the initial Interest Period shall
commence on the Borrowing Date and each subsequent Interest Period shall
commence on the date on which the immediately preceding Interest Period
applicable thereto expires; (b) if any Interest Period would otherwise end on a
day that is not a Business Day, such Interest Period shall be extended to the
next succeeding Business Day unless the result of such extension would be to
carry such Interest Period into another calendar month in which event such
Interest Period shall end on the immediately preceding Business Day; (c) any
Interest Period that would otherwise extend beyond the Maturity Date shall end
on the Maturity Date; and (d) any Interest Period that begins on the last
Business Day of a calendar month (or on a day for which there is no numerically
corresponding day in the calendar month at the end of such Interest Period)
shall end on the last Business Day of a calendar month.

              2.11 Interest Reserve. Notwithstanding anything herein to the
contrary, the Borrower acknowledges and agrees that on the Borrowing Date an
amount equal to three months' interest in respect of the principal amount of the
Loans shall be deposited with, and held by, the Collateral Agents under and
pursuant to the terms of the Disbursement Agreement.

                                      -23-
<PAGE>   29
              Section 3. Fees. The Borrower agrees to pay to the Administrative
Agents, for its own account, and to each Arranger, for their respective
accounts, such fees as have been agreed to in writing by the Borrower, the
Administrative Agents and the Arrangers, respectively.

              Section 4. Prepayments; Payments.

              4.1 Voluntary Prepayments. The Borrower shall have the right to
prepay the Loans, without premium or penalty, in whole or in part at any time
and from time to time after the Borrowing Date of such Loans on the following
terms and conditions: (i) the Borrower shall give the Administrative Agents at
the Notice Office at least five Business Days' prior written notice of its
intent to prepay the Loans and the aggregate principal amount of the prepayment
(which notice the Administrative Agents shall promptly transmit to each of the
Lenders); (ii) such prepayment shall be in an aggregate principal amount of at
least U.S.$1,000,000 or whole multiples thereof; (iii) prepayments of a Loan may
only be made pursuant to this Section 4.1 on the last day of an Interest Period
applicable thereto, unless the Borrower pays, together with any such prepayment,
all amounts owing under Section 2.8, if any, as a result of prepaying such Loan
on a day other than the last day of the Interest Period applicable thereto; (iv)
each prepayment shall be applied to reduce the then remaining Scheduled
Repayments on the Loans in order of maturity (or as otherwise agreed in writing
between the Borrower and the Lenders); and (v) the Borrower shall have provided
reasonable assurances satisfactory in all respects to the Administrative Agents
that the prepayment does not violate any applicable Law.

              4.2 Mandatory Repayments. (a) In addition to any other mandatory
repayments pursuant to this Section 4.2, on each date set forth below, the
Borrower shall be required to repay that principal amount of Loans, to the
extent then outstanding, as is set forth opposite such date (each such
repayment, a "Scheduled Repayment," and each such date, a "Scheduled Repayment
Date"):

                                      -24-
<PAGE>   30
; and the balance of the principal amount of each Loan shall be paid on the
Maturity Date.

              (b) In addition to any other mandatory repayments pursuant to this
Section 4.2, if at any time after the Borrowing Date, the Borrower receives any
cash proceeds from the sale or issuance of equity in the Borrower (other than
from a Permitted Equity Offering), which exceed, either individually or in the
aggregate, U.S.$30,000,000 or from any issuance or incurrence of Indebtedness
(other than Indebtedness permitted pursuant to Section 8.3), then the Borrower
shall apply an amount equal to (i) 100% of the cash proceeds of the respective
issuance or incurrence of Indebtedness and (ii) that amount of the respective
issuance of equity which exceeds U.S.$30,000,000 (in each case net of
underwriting discounts and commissions and other reasonable costs associated
therewith, including legal, accounting, investment banking, consulting,
governmental and other fees incurred or reasonably expected to be incurred and
net of taxes paid or payable in respect thereof) as a mandatory repayment of
principal of any outstanding Loans by reducing the then remaining Scheduled
Repayments in order of maturity (or as otherwise agreed to in writing between
the Borrower and the Lenders). Any mandatory repayment due and owing pursuant to
the operation of this Section 4.2(b) shall be made at the end of the Interest
Period next following the date of receipt by the Borrower of the proceeds of
such offering or Indebtedness. If, and to the extent, the application of such
proceeds to the repayment of the Loans is prohibited or restricted in any manner
under applicable Law (including, without limitation, if the Central Bank
requires the payment of any taxes or mandatory deposits with respect to such
repayment), then, subject to Section 11.10, such proceeds to the extent of such
prohibition or restriction shall not be prepaid but shall be deposited into an
interest bearing escrow account by the Borrower with, and held by, the
Collateral Agents pursuant to the Disbursement Agreement.

              (c) In addition to any other mandatory repayments pursuant to this
Section 4.2, on each Excess Cash Payment Date, the Borrower shall pay to the
Administrative Agents an amount equal to 50% of the Excess Cash Flow for each
relevant Excess Cash Payment Period (the "Excess Cash Flow Payment"), each such
amount to be applied as a mandatory repayment of principal of outstanding Loans
to reduce the then remaining Scheduled Repayments in order of maturity after
giving effect to all prior reductions thereto. If any such Excess Cash Flow
Payment is prohibited or restricted in any manner under applicable Law
(including, without limitation, if the Central

                                      -25-
<PAGE>   31
Bank requires the payment of any taxes or mandatory deposits with respect to
such repayment), then, subject to Section 11.10, such Excess Cash Flow Payments
to the extent of such prohibition or restriction shall not be prepaid but shall
be deposited into an interest bearing account by the Borrower with, and held by,
the Collateral Agents pursuant to the Disbursement Agreement.

              4.3 Method and Place of Payment. Except as otherwise specifically
provided herein, all payments under this Agreement or any Note shall be made to
the Administrative Agents for the account of the Lender or Lenders entitled
thereto not later than 12:00 Noon (New York time) on the date when due and shall
be made in Dollars in immediately available funds at the Payment Office.
Whenever any principal payment to be made hereunder or under any Note shall be
stated to be due on a day which is not a Business Day, the due date thereof
shall be extended to the next succeeding Business Day, and interest shall be
payable at the applicable rate during such extension.

              4.4 Net Payments. (a) All payments made by the Borrower hereunder
or under any Note will be made without setoff, counterclaim or other defense.
All such payments will be made free and clear of, and without deduction or
withholding for, any present or future taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or hereafter imposed by
Colombia or any other jurisdiction from which the Borrower elects to make
payments or by any political subdivisions or taxing authorities thereof or
therein excluding in the case of each Lender, the Administrative Agents and the
Collateral Agents, taxes that would not be imposed but for a connection between
such Lender, the Administrative Agents and the Collateral Agents (as the case
may be) and the jurisdiction imposing such tax other than a connection arising
solely by virtue of the activities of such Lender, the Administrative Agents and
the Collateral Agents (as the case may be) pursuant to or in respect of this
Agreement or under any other Credit Document, including entering into, lending
money or extending credit pursuant to, receiving payments under, or enforcing,
this Agreement or any other Credit Document (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). If any Taxes are so levied or imposed, the
Borrower agrees to pay the full amount of such Taxes and such additional amounts
as may be necessary so that every payment of all amounts due hereunder or under
any Note, after withholding or deduction for or on account of any Taxes, will
not be less than the

                                      -26-
<PAGE>   32
amount provided for herein or in such Note. The Borrower will furnish to the
Administrative Agents within 45 days after the date the payment of any Taxes is
due pursuant to applicable Law certified copies of tax receipts evidencing such
payment by the Borrower. The Borrower will indemnify and hold harmless each
Lender, and reimburse such Lender upon its written request, for the amount of
any Taxes so levied or imposed and paid by such Lender.

              (b) If the Borrower pays any additional amount pursuant to this
Section 4.4 and any Lender actually receives a refund of tax or a credit against
such Lender's tax liabilities as a result of such payment by the Borrower, such
Lender shall promptly pay to the Borrower an amount that such Lender determines,
in its sole judgment, is equal to (i) in the case of a refund of tax, the amount
of such refund actually received by such Lender as a result of such payment by
the Borrower, and (ii) in the case of a credit against its tax liabilities, the
net tax benefit obtained by such Lender as a result of such payment by the
Borrower. Whether or not any Lender claims any credit or refund shall be in the
sole discretion of each Lender. If any Lender makes a payment to the Borrower
pursuant to this Section 4.4(b) and at any time thereafter such Lender
determines in its sole judgment that it is required to repay the refund or has
been or will be denied the benefit of the credit, as the case may be, which gave
rise to the payment to the Borrower, then the Borrower shall repay to such
Lender, promptly upon the request of such Lender, the amount previously paid by
the Lender pursuant to this Section 4.4(b). Nothing in this Section 4.4 shall
require any Lender to disclose or detail the basis of its calculation of the
amount of any tax benefit or any other information to the Borrower or any other
party. Each Lender shall use its reasonable efforts (consistent with legal and
regulatory restrictions) to file any certificate or document reasonably
requested in writing by the Borrower, if the making of such filing would avoid
the need for or reduce the amount of any additional amounts that would be
payable or may hereafter accrue and would not be otherwise disadvantageous to
such Lender.

              Section 5. Conditions Precedent.

              5.1 Conditions Precedent to the Borrowing. The obligation of each
Lender to make the Loans on the Borrowing Date is subject, at the time of the
Borrowing, to the satisfaction of the following conditions:

              (d) Officer's Certificate. On the Borrowing Date, the
Administrative Agents shall have received a certificate, dated the Borrowing

rights generally or by general equitable principles and (y) the remedies under
the Pledge Agreement-License can only be exercised after March 28, 1997.

known conflict with the rights of others which, or the failure to obtain which,
as the case may be, could result in a Material Adverse Effect on the Borrower.

trust collateral described therein, and (ii) the provisions of the Pledge
Agreement-License are effective to pledge to the Collateral Agents as security
for the Obligations hereunder, for the benefit of the Lenders, all of the
Borrower's right, title and interest in and to the License and the other trust
collateral described therein, except for (w) tax and labor liabilities as
provided by Colombian Law, (x) payments to the Ministry in accordance with the
License, (y) Liens permitted by Section 8.1, and except as such enforcement may
be limited by applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization or by other similar Laws relating to or limiting creditors'
rights generally or by general equitable principles and (z) Existing
Indebtedness or Contingent Obligations existing prior to the execution of the
Guaranty Trust Agreement or the Pledge Agreement-License upon which the
creditors exercise the rights granted under Article 1238 of the Colombian
Commerce Code and the rights of the Guaranty Trustee and the Collateral Agents,
as the case may be, for the benefit of the Lenders, in and to the Cellular
Receivables and the License, as the case may be, supersede, or by the Borrowing
Date will supersede, any rights, interests or Liens of any other Person therein;
provided, however, that (1) in accordance with the terms of the License and
applicable Law in effect as of the Borrowing Date, the Collateral Agents, for
the benefit of the Lenders, may not exercise any remedies with respect to the
License in accordance with the terms of the Pledge Agreement-License until March
28, 1997 and (2) the foregoing assumes that the Guaranty Trustee shall have paid
the Existing Indebtedness set forth in Schedule III to be repaid with the
proceeds of the Loans and the Debt Offering in accordance with the terms of the
Guaranty Trusts Termination Agreement.

                  (c) The provisions of the Disbursement Agreement create, or by
the Borrowing Date will create, in favor of the Collateral Agents for the
benefit of the Lenders, a legal, valid and enforceable security interest in the
collateral described therein, subject to no other Liens.

                  6.22 Mandate. The Borrower has, or by the Borrowing Date will
have, duly executed and delivered the Mandate and the Mandate constitutes or,
when executed and delivered, will constitute, its legal, valid and binding
obligation enforceable in accordance with its terms, except as such enforcement
may be limited by applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization or other similar Laws relating to or limiting creditors' rights
generally or by general equity principles.

                  6.23 Availability and Transfer of Foreign Currency. All
requisite foreign exchange control approvals and other authorizations by
Colombia or any department or agency thereof have been duly obtained and are in
full force and effect to assure the availability of Dollars to enable the
Borrower to perform all of its obligations under each Credit Document to which
it is party in accordance with the terms thereof. Subject to the Colombian Law
which permits Colombian authorities to limit the availability or transfer of
foreign exchange whenever foreign currency reserves fall below the equivalent of
three months' imports into Colombia, there are no restrictions or requirements
which limit the availability or transfer of foreign exchange for the purpose of
the performance by the Borrower of its obligations under this Agreement or any
other Credit Document to which it is party.

                  6.24 Nature of Activities. The Borrower has engaged in no

including, without limitation, stamp, transaction, registration or similar
taxes, are required to be paid for the legality, validity, or enforceability of
this Agreement or any of the other Credit Documents. This Agreement and each
other Credit Document are each in proper legal form under the Laws of Colombia,
and under the respective governing Laws selected in such Credit Documents, for
the enforcement thereof in such jurisdiction without any further action by any
Other Document Party, the Guaranty Trustee, the Collateral Agents or the
Administrative Agents.

                  6.26 Withholding Taxes. No withholding or similar taxes are
required to be paid in respect of, or deducted from, any payment required to be
made by the Borrower under this Agreement or any other Credit Document.

                  6.27 Properties and Insurance. All tangible properties of the
Borrower utilized in the Business are in good working order and condition
(except to the extent as could not have a Material Adverse Effect on the
Borrower). The Borrower maintains insurance with financially sound and reputable
insurers against losses, damages or other risks (including, without limitation,
risks and liability to Persons and property) in such manner and to the same
extent as other companies in the business of constructing, owning and operating
a cellular telephone network in Colombia.

or levies imposed upon it or upon its income or profits or upon any of its
property, real, personal or mixed or upon any part thereof, when due, as well as

future agreement or instrument necessary to the Business by which it is party or
by which it is bound, including, without limitation, all interconnection

     detract from the value of the Borrower's property or assets or materially

which is to remain outstanding after the Borrowing Date pursuant to Schedule

     the Indebtedness so refinanced; (iii) any such refinanced Indebtedness
     shall be in a principal amount that does not exceed (x) the principal
     amount (or, if such Indebtedness being refinanced was incurred with
     original issue discount, the aggregate accreted value as of the date of
     determination) so refinanced, plus (y) the lesser of the amount of any
     premium required to be paid in connection with such refinancing pursuant to
     the terms of the amount of any premium reasonably determined as necessary
     to accomplish such refinancing, plus (z) the amount of any fees and

         9.9 License. (i) The Ministry or any other governmental authority in
Colombia shall declare the License terminated; (ii) the License shall terminate
for any reason whatsoever; (iii) the Borrower shall cease to have the right to

<PAGE>   62

other governmental authority in Colombia or any Other Document Party shall

the Borrower or any action that would prevent the Borrower or its officers from
carrying on the Business or a substantial part thereof;

then, and in any such event, and at any time thereafter, if any Event of Default
shall then be continuing, then the Administrative Agents shall at the request of
the Required Lenders, or may with the consent of the Required Lenders, by
written notice to the Borrower, take any and all of the following actions,
without prejudice to the rights of the Administrative Agents, any Lender or the
holder of any Note to enforce its claims against the Borrower (provided, that,
if an Event of Default specified in Section 9.5 shall occur with respect to the
Borrower, the result which would occur upon the giving of written notice by the
Administrative Agents to the Borrower as specified in clause (i) and (ii) below
shall occur automatically without the giving of any such notice): (i) to declare

whereupon the same shall become, forthwith due and payable without presentment,

                                      -58-
<PAGE>   64

Lien thereon for the benefit of the Lenders in the manner provided herein and in
the other Credit Documents. The Collateral Agents shall exercise such rights and
remedies with respect to the Collateral as are granted to them hereunder and
under the other Credit Documents and applicable Law and as shall be directed by
the Required Lenders.

         10.4 Application of Proceeds. Except as otherwise specifically provided
in any Security Document, the proceeds of any collection, sale, disposition or
other realization of all or any part of the Collateral shall be applied by the

     reasonable attorneys' fees) incurred by the Collateral Agents in obtaining,
     taking possession of, removing, insuring, repairing, storing and disposing
     of the Collateral and any and all amounts incurred by the Collateral Agents
     in connection therewith;

         (b) next, any surplus then remaining to the payment of the Obligations
     in the following order of priority:

         (c) any surplus remaining after payment of the foregoing amounts shall

<PAGE>   65
         10.5 Nature of Duties. Neither the Administrative Agents nor the
Collateral Agents shall have any duties or responsibilities except those
expressly set forth in this Agreement and in the other Credit Documents. Neither
the Administrative Agents nor the Collateral Agents nor any of their respective
officers, directors, agents or employees shall be liable for any action taken or
omitted by them hereunder or under any other Credit Document or in connection
herewith or therewith, unless caused by their gross negligence, fraud or willful
misconduct. The duties of the Administrative Agents and the Collateral Agents
shall be mechanical and administrative in nature; neither the Administrative
Agents nor the Collateral Agents shall have by reason of this Agreement or any
other Credit Document a fiduciary relationship in respect of any Lender or the
holder of any Note; and nothing in this Agreement or any other Credit Document,
expressed or implied, is intended to or shall be so construed as to impose upon
the Administrative Agents or the Collateral Agents any obligations in respect of
this Agreement or any other Credit Document except as expressly set forth herein
or therein.

         10.6 No Reliance on the Administrative Agents and the Collateral
Agents. Independently and without reliance upon the Administrative Agents or the
Collateral Agents, each Lender and the holder of each Note, to the extent it
deems appropriate, has made and shall continue to make (i) its own independent
investigation of the financial condition and affairs of each of the Other
Document Parties in connection with the making and the continuance of the Loans
and the taking or not taking of any action in connection herewith and (ii) its
own appraisal of the creditworthiness of each of the Other Document Parties and,
except as expressly provided in this Agreement, neither the Administrative
Agents nor the Collateral Agents shall have any duty or responsibility, either
initially or on a continuing basis, to provide any Lender or the holder of any
Note with any credit or other information with respect thereto, whether coming
into its possession before the making of the Loans or at any time or times
thereafter. Neither the Administrative Agents nor the Collateral Agents shall be
responsible to any Lender or the holder of any Note for any recitals,
statements, information, representations or warranties herein or in any
document, certificate or other writing delivered in connection herewith or for
the execution, effectiveness, genuineness, validity, enforceability, perfection,
collectibility, priority or sufficiency of this Agreement or any other Document
or the financial condition of any Other Document Party or be required to make
any inquiry concerning either the perfor-

                                      -60-
<PAGE>   66

mance or observance of any of the terms, provisions or conditions of this
Agreement or any other Credit Document, or the financial condition of any Other
Document Party or the existence or possible existence of any Default or Event of
Default.

         10.7 Certain Rights of the Administrative Agents and the Collateral
Agents. If either the Administrative Agents or the Collateral Agents shall
request instructions from the Required Lenders with respect to any act or action
(including failure to act) in connection with this Agreement or any other
Document, then the Administrative Agents or Collateral Agents requesting such
instructions shall be entitled to refrain from such act or taking such action
unless and until it shall have received instructions from the Required Lenders;
and, in any such event, neither the Administrative Agents nor Collateral Agents,
as the case may be, shall incur any liability to any Person by reason of so
refraining. Without limiting the generality of the foregoing, no Lender or the
holder of any Note shall have any right of action whatsoever against the
Administrative Agents or the Collateral Agents as a result of acting or
refraining from acting hereunder or under any other Document in accordance with
the instructions of the Required Lenders.

         10.8 Reliance by the Administrative Agents and the Collateral Agents.
Each of the Administrative Agents and the Collateral Agents shall be entitled to
rely, and shall be fully protected in relying, upon any note, writing,
resolution, notice, statement, certificate, telex, teletype or facsimile
message, cablegram, radiogram, order or other document or telephone message
signed, sent or made by any Person that the Administrative Agents or Collateral
Agents, as the case may be, believed to be the proper Person, and, with respect
to all legal matters pertaining to this Agreement and any other Credit Document
and their duties hereunder and thereunder, upon advice of counsel selected by
it.

         10.9 Indemnification. To the extent the Administrative Agents or the
Collateral Agents are not reimbursed and indemnified by the Borrower, the
Lenders will reimburse and indemnify the Administrative Agents or the Collateral
Agents, as the case may be, in proportion to the Lenders' outstanding Notes, for
and against any and all liabilities, obligations, losses, damages, penalties,
claims, actions, judgments, suits, costs, expenses or disbursements of
whatsoever kind or nature which may be imposed on, asserted against or incurred
by the Administrative Agents or

                                      -61-
<PAGE>   67

the Collateral Agents, as the case may be, in performing their duties hereunder
or under any other Credit Document, or in any way relating to or arising out of
this Agreement or any other Credit Document, provided that no Lender shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the gross negligence or willful misconduct of the Administrative Agents or
the Collateral Agents.

         10.10 Capacity as Lenders. Each of the Administrative Agents and the
Collateral Agents may accept deposits from, lend money to, and generally engage
in any kind of banking, trust or other business with the Borrower or any
Affiliate of the Borrower as if such Administrative Agents or Collateral Agents
were not performing the duties specified herein, and may accept fees and other
consideration from the Borrower for services in connection with this Agreement
and otherwise without having to account for the same to the Lenders.

         10.11 Holders. Each of the Administrative Agents and the Collateral
Agents may deem and treat the payee of any Note as the owner thereof for all
purposes hereof unless and until a written notice of the assignment, transfer or
endorsement thereof, as the case may be, shall have been filed with the
Administrative Agents. Any request, authority or consent of any Person who, at
the time of making such request or giving such authority or consent, is the
holder of any Note shall be conclusive and binding on any subsequent holder,
transferee, assignee or indorsee, as the case may be, of such Note or of any
Note or Notes issued in exchange therefor.

         10.12 Resignation. (a) Both or either ING (U.S.) Capital Corporation
and/or ING Bank N.V. may resign from the performance of its (or their, as the
case may be) duties as Administrative Agent and/or Collateral Agent (or
Administrative Agents and/or Collateral Agents) hereunder and/or under the other
Credit Documents at any time by giving 60 Business Days' prior written notice to
the Borrower and the Lenders. Such resignation shall take effect upon the
appointment of a successor Administrative Agent or Collateral Agent (or
successor Administrative Agents or Collateral Agents), as the case may be,
pursuant to clauses (b) and (c) below or as otherwise provided below.

         (b) Upon any such notice of resignation, the Required Lenders shall
appoint a successor Administrative

                                      -62-

Agent or Collateral Agent (or Administrative Agents or Collateral Agents), as
the case may be, hereunder or thereunder which shall be an
internationally-recognized commercial bank or trust company acceptable to the
Borrower.

         (c) If a successor Administrative Agent or Collateral Agent (or
     Administrative Agents or Collateral Agents), as the case may be, shall not
     have been so appointed within such 60 Business Day period, the
     Administrative Agents and/or Collateral Agents, as the case may be, with
     the consent of the Borrower, may then appoint a successor Administrative
     Agent and/or Collateral Agent, as the case may be, which shall serve as
     such hereunder or thereunder until such time, if any, as the Required
     Lenders appoint a successor as provided above.

         (d) If no successor has been appointed pursuant to clause (b) or (c)
     above by the 70th Business Day after the date such notice of resignation
     was given by the Administrative Agent and/or the Collateral Agent (or
     Administrative Agents or Collateral Agents), as the case may be, the
     resignation shall become effective and the Lenders shall thereafter perform
     all the duties of the Administrative Agent and/or Collateral Agent (or
     Administrative Agents and/or Collateral Agents), as the case may be,
     hereunder and/or under any other Credit Document until such time, if any,
     as the Required Lenders appoint a successor as provided above.

         10.13 Joint Action. Any action, notice or similar action that the
Administrative Agents or the Collateral Agents shall take or give to the
Borrower, the Guaranty Trustee or the Designated Shareholders shall be taken or
given jointly.

printing, document

production and delivery, communication and travel costs) incurred in connection
with the preparation, review, negotiation, translation, execution and delivery
of this Agreement and the other Credit Documents and the documents and
instruments prepared in connection herewith or in anticipation hereof and any
amendment, waiver or consent relating hereto or thereto, provided that the
foregoing costs and expenses shall not exceed U.S.$210,000, exclusive of (A)
reasonable legal expenses incurred in relation to the enforcement of any
provision of the Loan Documents and (B) customary breakage costs incurred in
connection with the Loans (to be applied for the account of the Borrower), and
(y) the Administrative Agents, the Collateral Agents and each of the Lenders in
connection with the enforcement of this Agreement and the other Credit Documents
and the documents and instruments referred to herein and therein (including,
without limitation, the reasonable fees and disbursements of counsel for the
Administrative Agents and the Collateral Agents and for each of the Lenders);
(ii) pay and hold each of the Lenders harmless from and against any and all
present and future stamp and other similar taxes with respect to the foregoing
matters and save and hold each of the Lenders harmless from and against any and
all liabilities with respect to or resulting from any delay or omission (other
than to the extent attributable to such Lender) to pay such taxes; and (iii)
indemnify the Administrative Agents, the Collateral Agents and each Lender, and
their respective officers, directors, employees, representatives and agents
(each an "indemnified person") from and hold each of them harmless against any
and all liabilities, obligations, losses, damages, penalties, claims, actions,
judgments, suits, costs, expenses and disbursements (collectively, "Losses")
incurred by any of them as a result of, or arising out of, or in any way related
to, or by reason of, any investigation, litigation or other proceeding (whether
or not the indemnified person is a party thereto) related to the entering into
and/or performance of this Agreement or any other Credit Document or the use of
the proceeds of any Loans hereunder or the consummation of any transactions
contemplated herein or in any other Credit Document, including, without
limitation, the reasonable fees and disbursements of counsel incurred in
connection with any such investigation, litigation or other proceeding and any
loss, expense or liability incurred by reason of the liquidation or reemployment
of deposits or other funds required by such Lender which any Lender may sustain
as a result of any default by the Borrower to repay the Loans when required
pursuant to the terms of this Agreement or the Notes (but excluding any such
Losses, to the extent incurred by reason

                                      -64-
<PAGE>   70

of the gross negligence, fraud or willful misconduct of the indemnified person),
provided that if an indemnified person is entitled to indemnification under this
subclause (iii), the Borrower shall be entitled to assume the defense of any
action, claim or proceeding with counsel reasonably satisfactory to such
indemnified person. The Borrower will not, without the prior written consent of
each indemnified person, settle any pending or threatened action, claim or
proceeding in respect of which indemnification may be sought hereunder unless
such settlement includes an unconditional release of each indemnified person
from all liability arising out of such action, claim or proceeding. Upon
assumption by the Borrower of the defense of any such action, claim or
proceeding, the indemnified person shall have the right to participate in such
action, claim or proceeding and to retain its own lawyers but the Borrower shall
not be liable for any legal fees or expenses subsequently incurred by such
indemnified person in connection therewith.

         11.2 Right of Setoff. In addition to any rights now or hereafter
granted under applicable Law or otherwise, and not by way of limitation of any
such rights, upon the occurrence of an Event of Default and the continuance
thereof, the Administrative Agents and each Lender is hereby authorized at any
time or from time to time, without presentment, demand, protest or other
notice of any kind to the Borrower or to any other Person, any such notice being
hereby expressly waived, to set off and to appropriate and apply any and all
deposits (general or special) and any other Indebtedness at any time held or
owing by such Lender (including, without limitation, by branches and agencies of
such Lender wherever located) to or for the credit or the account of the
Borrower against and on account of the Obligations of the Borrower to such
Lender or the Administrative Agents under this Agreement or under any of the
other Credit Documents, including, without limitation, all interests in
Obligations purchased by such Lender pursuant to Section 11.7(b), and all other
claims of any nature or description arising out of or connected with this
Agreement or any other Credit Document, irrespective of whether (i) such Lender
or the Administrative Agents shall have made any demand hereunder, or (ii) said
Obligations, liabilities or claims, or any of them, shall be unmatured.

         11.3 Notices. Except as otherwise expressly provided herein, all
notices and other communications provided for hereunder shall be in writing
(including telex or facsimile communication) and telexed, faxed or delivered: if
to the Borrower, at its address specified opposite its

                                      -65-
<PAGE>   71

signature below; if to any Lender, at its Lending Office specified opposite its
name on Schedule II; if to the Administrative Agents, at the Notice Office; and
if to the Collateral Agents, at its address specified in the Disbursement
Agreement; or, as to the Borrower, the Administrative Agents or Collateral
Agents, at such other address as shall be designated by such party in a written
notice to the other parties hereto, and, as to each other party, at such other
address as shall be designated by such party in a written notice to the
Borrower, the Collateral Agents and the Administrative Agents. All such notices
and communications shall, when faxed, telexed or delivered, be effective when
the facsimile is confirmed, confirmed by telex answerback or delivered by the
overnight courier company, respectively. All such notices and other
communications, if not in English, shall be accompanied by an English
translation.

         11.4 Benefit of Agreement. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the respective successors and
permitted assigns of the parties hereto, provided that the Borrower may not
assign or transfer any of its rights or obligations hereunder without the prior
written consent of the Lenders. The Lenders may assign their rights only as
provided in Section 11.5.

         11.5 Syndication or Assignment of Loans. (a) Each Lender may, subject
to Colombian Law, at any time (i) grant participations in the Loans made
hereunder or (ii) upon prior written notice to the Administrative Agents,
transfer or assign, any of its rights hereunder or under any of the Notes;
provided, however that (x) any transfer or assignment by a Lender to any lending
institution other than to (1) an Affiliate of such Lender, or (2) one of the
other Lenders or any of its Affiliates, of a portion of its rights hereunder or
under any Note shall not be for an amount less than U.S.$2,000,000 or a higher
integral multiple of $1,000,000 in each instance, (y) each such assignment shall
be of a uniform, and not a varying, percentage of all rights and obligations
under this Agreement, and (z) unless the assignment is to an existing Lender or
an Affiliate of the assigning Lender, the Borrower shall have notified the
assigning Lender within five Business Days of the Borrower's receipt of notice
of such assignment of the Borrower's approval of such assignment (such approval
not to be unreasonably withheld or delayed) and if the Borrower has not notified
the assigning Lender of its approval or disapproval of such assignment by such
date, the Borrower shall be deemed

                                      -66-
<PAGE>   72

to have given its approval. If any Lender transfers or assigns any portion or
all of its rights hereunder or under the Notes to any other financial
institution, any reference to such Lender in this Agreement or the Note of such
Lender shall thereafter refer to such Lender and to such other financial
institution to the extent of their respective interests, as if such Lender had
been a party to this Agreement as of the Effective Date up to and including the
date of such transfer or assignment.

         (b) Notwithstanding any provision in this Agreement, the Borrower shall
not be obligated to pay to the successor or assignee of any Lender (including
any Affiliate thereof) any greater amount than the Borrower would have been
obligated to pay for the account of such Lender or Affiliate as of the date of
such assignment or other transfer; provided, however, that the foregoing shall
not limit in any manner whatsoever the Borrower's obligation to pay any such
greater amount in accordance with the terms of this Agreement as a result of any
change (including, without limitation, by reason of a change in interpretation
or administration of any Law or the introduction or implementation of any new
Law), applicable to such successor or assignee of such Lender (including any
Affiliate thereof) after the date of such assignment or other transfer.

         11.6 No Waiver; Remedies Cumulative. No (i) failure or delay on the
part of the Administrative Agents, the Collateral Agents or any Lender or the
holder of any Note in exercising any right, power or privilege hereunder or
under any other Credit Document or (ii) course of dealing between the Borrower
and the Administrative Agents, the Collateral Agents or any Lender or the holder
of any Note, shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Credit Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agents, the Collateral Agents or any Lender or the holder of any
Note would otherwise have. No notice to or demand on the Borrower in any case
shall entitle the Borrower to any other or further notice or demand in similar
or other circumstances or constitute a waiver of the rights of the
Administrative Agents, the Collateral Agents or any Lender or the holder of any
Note to any other or further action in any circumstances without notice or
demand.

                                      -67-
<PAGE>   73
         11.7 Payments Pro Rata. (a) The Administrative Agents agree that
promptly after their receipt of each payment from or on behalf of the Borrower
in respect of any Obligations of the Borrower hereunder, they shall distribute
such payment to the Lenders pro rata based upon their respective shares, if any,
of the Obligations with respect to which such payment was received.

         (b) Each of the Lenders agrees that, if it should receive any amount
hereunder (whether by voluntary payment, realization upon security, the exercise
of the right of set-off or banker's lien, counterclaim or cross action, the
enforcement of any right under the Credit Documents, or otherwise), which is
applicable to the payment of the principal of, or interest on, the Loans or any
Fee, of a sum which with respect to the related sum or sums received by other
Lenders is in a greater proportion than the total amount of such Obligation then
owed and due to such Lender bears to the total amount of such Obligation then
owed and due to all the Lenders immediately prior to such receipt, then such
Lender receiving such excess payment shall purchase for cash without recourse or
warranty from the other Lenders an interest in the Obligations of the Borrower
to such Lenders in such amount as shall result in a proportional participation
by all the Lenders in such amount; provided, however, that if all or any portion
of such excess amount is thereafter recovered from such Lender, such purchase
shall be rescinded and the purchase price restored to the extent of such
recovery, but without interest.

         11.8 Calculations; Computations. (a) The financial statements to be
furnished to the Lenders pursuant hereto shall be made and prepared in
accordance with Colombian GAAP (except as set forth in the notes thereto or as
otherwise disclosed in writing by the Borrower to the Lenders).

         (b) All computations of interest and Fees hereunder shall be made on
the basis of a year of 360 days for the actual number of days (including the
first day but excluding the last day) occurring in the period for which such
interest or Fees are payable.

         11.9 Governing Law; Submission to Jurisdiction; Venue. (a) This
Agreement, the Notes, the Mandate and the Disbursement Agreement and the rights
and obligations of the parties hereunder and thereunder shall be construed in
accordance with and be governed by the Law of the State of New York without
giving effect to the principles thereof

                                      -68-

relating to conflicts of law except Section 5-1401 of the New York General
Obligations Law. Any legal action or proceeding with respect to this Agreement
or any other Credit Document (except as is otherwise provided in such Credit
Document) may be brought in the courts of the State of New York sitting in the
City and the County of New York, of the United States for the Southern District
of New York, and, by execution and delivery of this Agreement, each of the
parties hereto other than Export Development Corporation hereby irrevocably
accepts for itself and in respect of its property, generally and
unconditionally, the non-exclusive jurisdiction of the aforesaid courts. The
Borrower hereby irrevocably designates, appoints and empowers the Process Agent,
as its designee, appointee and agents to receive, accept and acknowledge for and
on its behalf, and in respect of its property, service of any and all legal
process, summons, notices and documents which may be served in any such action
or proceeding. If for any reason such designee, appointee and agents shall cease
to be available to act as such, the Borrower agrees to designate a new designee,
appointee and agents in New York City on the same terms and for the purposes of
this provision reasonably satisfactory to the Administrative Agents. The
Borrower further irrevocably consents to the service of process out of any of
the aforementioned courts in any such action or proceeding by the mailing of
copies thereof by registered or certified mail, postage prepaid, to the Borrower
at its address set forth opposite its signature below, such service to become
effective 30 days after such mailing. Nothing herein shall affect the right of
the Administrative Agents, the Collateral Agents, any Lender or the holder of
any Note to serve process in any other manner permitted by Law or to commence
legal proceedings or otherwise proceed against the Borrower in any other
jurisdiction.

         (b) Each of the Pledge Agreements, the Guaranty Trust Agreements and
the Pledge Agreement-License shall be governed entirely by the Law of the
Republic of Colombia, and therefore Colombian courts will be the only courts
that will have jurisdiction over any action brought in connection with each of
the Pledge Agreements, the Guaranty Trust Agreements and the Pledge
Agreement-License, as the case may be.

         (c) The Borrower hereby irrevocably waives any objection which it may
now or hereafter have to the laying of venue of any of the aforesaid actions or
proceedings arising out of or in connection with this Agreement or any other
Credit Document brought in the courts referred to in clauses (a) and (b) above
and hereby further irrevocably waives and

                                      -69-
<PAGE>   75
agrees not to plead or claim in any such court that any such action or
proceeding brought in any such court has been brought in an inconvenient forum.

         (d) The Borrower agrees, to the extent permitted by applicable Law,
that in any legal action or proceeding arising out of or in connection with this
Agreement or any other Credit Document (the "Proceedings") anywhere (whether for
an injunction, specific performance, damages or otherwise), no sovereign
immunity (to the extent that it may at any time exist) from those Proceedings,
from attachment (whether in aid of execution, before judgment or otherwise), or
from judgment shall be claimed by it or on its behalf or with respect to its
assets.

         11.10 Obligation to Make Payments in Dollars. Notwithstanding anything
herein to the contrary, the obligation of the Borrower to make payment in
Dollars of the principal of and interest on the Notes and any other amounts due
hereunder or under any other Credit Document to the Payment Office of the
Administrative Agents as provided in Section 4.3 shall not be discharged or
satisfied by any tender, or any recovery pursuant to any judgment, which is
expressed in or converted into any currency other than Dollars, including,
without limitation, any deposit in an escrow account pursuant to Section 4.2(b)
or Section 4.2(c) of proceeds of an equity offering or the incurrence of
Indebtedness or any Excess Cash Flow Payment, respectively, except to the extent
such tender or recovery shall result in the actual receipt by the Administrative
Agents at its Payment Office on behalf of the Lenders or holders of the Notes of
the full amount of Dollars expressed to be payable in respect of the principal
of and interest on the Notes and all other amounts due hereunder or under any
other Credit Document. The obligation of the Borrower to make payments in
Dollars as aforesaid shall be enforceable as an alternative or additional cause
of action for the purpose of recovery in Dollars of the amount, if any, by which
such actual receipt is less than the full amount of Dollars expressed to be
payable in respect of the principal of and interest on the Notes and any other
amounts due under any other Credit Document, and shall not be affected by
judgment being obtained for any other sums due under this Agreement or under any
other Credit Document.

         11.11 Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts,

which

                                      -70-

delivered the same to the Administrative Agents at the Notice Office or, in the
case of the Lenders, shall have given to the Administrative Agents telephone

terminated unless such change, waiver, discharge or termination is in writing
signed by the Required Lenders, the Administrative Agents and the Borrower (or
the Designated Shareholders or the Guaranty Trustee, if applicable); provided,
however, that no such change, waiver, discharge or termination shall, without
the consent of each Lender (which is the duty of the Administrative Agents to
confirm), (i) extend the Maturity Date of any Loan or Note, or reduce the rate
or extend the time of payment of interest or Fees thereon, or reduce the
principal amount thereof, or increase the Commitment of any Lender over the
amount thereof then in effect (it being understood that a waiver of any Default
or Event of Default or of a mandatory reduction in the Total Commitment shall
not constitute a change in the terms of any Commitment of any Lender), (ii)
release any of the Collateral except as shall be otherwise provided in any
Credit Document, (iii) amend, modify or waive any provision of this Section 
11.14 or Sections 2.1, 11.1, 11.2, 11.4, 11.5 or 11.7(b), (iv) reduce the

CARIBE - CELULAR S.A. AND EMPRESAS MUNICIPALES DE CALI -
EMCALI

Between the undersigned, GILBERTO ECHEVERRI MEJIA, resident of Medellin, with
citizens card number 3.302.711 of Medellin, who is acting as the President and
Legal Representative of OCCIDENTE Y CARIBE CELULAR, S.A. - OCCEL S.A. - a mixed
economy society with private capital in the majority, domiciled in Pereira,
that for the effects of this agreement will be referred to as OCCEL, on one
part, and on the other part ADOLFO LEON GALLON LOZANO, resident of Cali,
identified with citizens card number 16.344.987 of Tulua (Valle), who is acting
as the General Manager and Legal Representative of EMPRESAS MUNICIPALES DE
CALI, Public Entity of Municipal order, who hereinafter will be referred to as
EMCALI, this interconnection agreement is concluded and shall be governed
pursuant to the clauses within this document, subject to the following
considerations and definitions:

CONSIDERATIONS:

FIRST.  OCCEL is the awardee of the concession which has as its object the
rendering of a Cellular Mobile Telephone Service on the "A" network in the
Western region of Colombia pursuant to agreement 000005 concluded with the
Ministry of Communications on March 28, 1994.

SECOND. The Law 37 of 1993 and the Decree 741 of the same year authorized the
access right of the Cellular Mobile Telephone operators (CTN) to the public
switched telephone networks (PSTN) already established in the country, for the
interconnection of the elements of their networks and to manage traffic, and
also stipulating the obligation of the public switched telephone network
operators to guarantee the access to their Mobile Switched Centers (MSC),
providing the facilities for the location of interconnection equipment within
equipment rooms of these centrals and, at the same time, the facilities of AC
power supply, preventive and corrective maintenance, and also the other
facilities that are technically and administratively required, all at the
expense of the Cellular Mobile Network Operator.

THIRD.  Interconnection will be subject to the equal access principle -
pursuant to article 66 Decree 741 of 1993 by virtue whereof the MSC operators
are obliged to provide interconnection under equal technical and economic
conditions to every CTN operator.

FOURTH.  By means of Resolution 002 of 1993, the Telecommunications Regulatory
Commission, exercising the powers conferred upon it by Decree 2122 of 1992,
established that for a one (1) year term from October thirteenth (13th) of
1993, the fee for the interconnection between the PSTN subscriber terminal and
the local switching center will be TWENTY-FOUR ($24) Colombian pesos per
minute, for both outgoing calls and incoming calls to the PSTN.  This tariff
was established based on the variables of cost per line, percentage of line
usage, operation costs, maintenance and
<PAGE>   2
management per line per year, line traffic per year, the useful life of the
equipment and network, the replacement thereof and the rate of discount or
reasonable profit to the PSTN operator.  Furthermore, by means of Resolution
004 of 1993 issued by the Telecommunications Regulatory Commission, the
principle was established whereby the party calling to or from the cellular
network must assume the costs thereof.  The Interconnection Fee stipulated
herein shall be adjusted once the EMCALI Board of Directors determines the
amount of adjustment.  The Board of Directors has the power to determine the
rate to be applied, which shall not exceed the maximum value pursuant to
Resolution No. 020 of February 20, 1995, Articles 2 and 3, issued by the
Telecommunications Regulatory Commission and subsequent regulations which amend
or supersede it.

<PAGE>   6
1.   EMCALI shall include in the bill for services to its subscribers or
     users the charges for calls which the consumers of its network originate to
     the OCCEL network, including access charges to the EMCALI PSTN and charges
     for usage of the OCCEL CTN.  EMCALI shall bill based on the call report
     and on the statement it will receive from OCCEL on magnetic tape or any
     other media agreed upon by the parties.

     EMCALI may verify the statement of charges for access charges to its PSTN
     submitted by OCCEL against the statement for control and verification
     purposes which EMCALI makes, based on calls recorded in their digital
     centrals.  In the event that the difference between the statements made by
     OCCEL and EMCALI as to the total value of the aforementioned access charges
     does not exceed the percentage which the executives designated by the
     parties for the administration of this contract have agreed to establish as
     the maximum tolerance, the bill shall be based on the information submitted
     by OCCEL.

     In the event that the aforementioned difference exceeds the maximum
     tolerance established, and there is no technical justification, the access
     charges shall be billed according to the higher records, whether the
     information corresponds to OCCEL or EMCALI.  If there is a technical
     justification, the billing shall be according to the information which is
     without errors, or by means of the combination of the OCCEL and EMCALI
     information.

     The parties shall agree monthly upon the dates and times for cutting the
     billing period.  EMCALI may include in the same bill the charges for other
     items and even charges from the other cellular network operators.  The bill
     will contain the information pursuant to Appendix No. 2 of this agreement.

     The incremental costs due to inclusion on bills issued by EMCALI of the
     global amount and the list of calls made by its subscribers from its PSTN
     to the OCCEL CTN, will be chargeable to OCCEL and will be paid pursuant to
     Appendix No. 2.

2.   To rebill the accounts including extra charge to the subscribers or
     users who have not paid the total amount of the OCCEL Cellular Mobile
     Telephone Service within the time limits stipulated to pay the bill.

3.   To maintain the records that could not be billed in each period (recycle)
     and are susceptible to be billed again in the next period, and submit a
     report of these amounts to OCCEL.  This point is applicable only in the
     cases in which subscribers are in the process of incorporation into the
     EMCALI subscriber files.  At maximum one recycle will be permitted; after
     this recycle the records will be permitted; after this recycle the records
     that had not been incorporated will be considered as inconsistencies with
     their respective justifications.

      late payment at the maximum rate legally accepted, pertaining to amounts
      that have not been collected within time limits stipulated on the bill,
      for calls transmitted to the OCCEL CTN.  These penalties or interest will
      be billed monthly for each month or fraction of delay and the money
      collected for this concept shall be applied proportionately to the amount
      of the balance corresponding to each party.  This penalty shall not apply
      in the event of an inevitable accident or force majeure.

        aforementioned date, that is, the final maturity date,
        the executives designated by parties shall reconcile
        the accounts in order to establish the difference
        between the amount transferred to OCCEL by EMCALI and
        that effectively collected for all concepts which
        correspond to OCCEL.  The payment of the amounts
        resulting must be made within the five (5) business
        days following the respective reconciliation date.

5.      EMCALI shall pay interest to OCCEL on late payment at a
        rate equivalent to the maximum allowed by Commercial
        Law for similar transactions, monthly or proportional
        to the days elapsed from the demandability of the debt
        to the verification date, due to the delay in the 
        payment of the amounts collected for the use of the 
        OCCEL CTN.  Excluded from this sanction are the delays
        due to force majeure or inevitable accident.

                 FINANCIAL, ECONOMIC AND ADMINISTRATIVE ASPECTS

FIRST CLAUSE - OBJECT:  The object of this Appendix is to supplement and
specify the procedures related to the financial, economic and administrative
aspects of the interconnection agreement.

SECOND CLAUSE - INFORMATION INCLUDED IN THE BILL:  The bill from EMCALI to its
subscribers, the information about calls originated by them to the OCCEL
cellular mobile telephone network, and the amount shall be presented in the
manner agreed upon by the parties agree within the thirty (30) days following
the concluding of this agreement.

THIRD CLAUSE - BILLING COSTS: OCCEL shall effect payment to EMCALI in the
amount of thirty ($30) pesos for each bill issued with calls to the OCCEL
network, plus seven ($7) pesos for every call to the OCCEL network which may
have been billed by EMCALI to their subscribers or users.  This amount includes

<PAGE>   24
CTN;  the parties shall agree as to the economic conditions under which EMCALI
will provide this space.

SIXTH CLAUSE - ANALYSIS AND RECOVERY OF FRAUDS AND INCONSISTENCIES:  An
inconsistency is considered to be all inaccurate information about data
concerning the recording, payment or billing of a call, which temporarily or
permanently makes the billing process and the charging of this call to the user
who actually made it impossible. There is temporary impossibility when the
inaccuracy is solved after an analysis which makes it possible to effect the
billing in a subsequent period.  There is permanent impossibility when, after
the respective analysis, it is determined that respective charge cannot be
collected.  Each party shall be liable to the other for payment for the
inconsistencies which arise due to calls which originated on its network, unless
it is proven that such inconsistencies are imputable to inaccuracies or errors
committed by the other party.

It is considered that a fraud has been committed when it has been determined
that collection cannot be effected for reasons other than the occurrence of an
inconsistency or the declaration that the debt assumed by the subscriber or user
generating is impossible to collect.

Fraudulent calls can be made from OCCEL or EMCALI networks, whether the origin
number has not been assigned to any subscriber or user, the calls have been
billed to disconnected telephones or those with a duly proven failure, or fraud
is caused by damage to the systems of billing or assessment of either the
parties, or by the improper usage of the telephone network by a non-identifiable
third party; in the latter event, exclusion shall be made of those cases in
which the subscriber's handset is used without his authorization.  In such
cases, each party shall be liable to the other for payment for the fraudulent
calls originated in its network.

In all cases where there is any suspicion of fraud, the executives in charge of
the management of this agreement shall determine the liability for the payment
of the fraudulent calls within sixty (60) days at maximum.  When within this
term no liability has been established, and the executives have not agreed as to
mutual exemption from liability to be borne by the parties, each party shall
have the right to proceed with legal suits in order for the liability for the
fraud to be established by the authority of jurisdiction.

SEVENTH CLAUSE - BALANCE CONFRONTATION AND RECONCILING OF ACCOUNTS:  EMCALI and
OCCEL shall maintain an accounting control which shall be reconciled monthly in
order to determine the net balance which the debtor party must pay to the
creditor party.  The dates for these reconcilings of accounts shall be agreed
upon by the executives responsible for the management of the agreement.  For the
effects of the reconciliation, parties may agree to offset accounts for the
leasing of systems and transmission media lease, leasing of facilities for
equipment location, leasing of electric and 
<PAGE>   25
air conditioning infrastructure, billing costs, payment for frauds and
inconsistencies, interest on late payment and any other concept related to the
execution of this agreement.

In testimony whereof this agreement is signed in the city of Cali on the _____
day of _______ of nineteen hundred and ninety-five (1995).

CONSIDERATIONS:

FIRST.  OCCEL is the awardee of the concession which has as its object the
rendering of a Cellular Mobile Telephone Service on the "A" network in the
Western region of Colombia pursuant to agreement 000005 concluded with the
Ministry of Communications on March 28, 1994.

SECOND.  The Law 37 of 1993 and the Decree 741 of the same year authorized the
access right of the Cellular Mobile Telephone operators (CTN) to the public
switched telephone networks (PSTN) already established in the country, for the
interconnection of the elements of their networks and to manage traffic, and
also stipulating the obligation of the public switched telephone network
operators to guarantee the access to their Mobile Switched Centers (MSC),
providing the facilities for the location of interconnection equipment within

        public phones.  Access shall be permitted only to public and semi-public
        telephones and which have the ability to charge for this type of calls,
        which must be connected to centrals with the ability to identify the "A"
        subscriber number.

10.     EPMZL must submit to OCCEL the identification number of the "A"
        subscriber who originates the call at the centrals of its PSTN when it
        is technically possible, in accordance with the schedule of replacement
        or upgrading of its telephone centrals.  EPMZL subscribers connected to
        centrals where the identification and automatic transmission of the "A"
        subscriber number is not possible are not allowed to access the OCCEL
        CTN.

11.     To repair, within the terms and conditions established by the executives
        responsible for the management of the contract, the failures reported by
        OCCEL.

12.     Not to discriminate against the OCCEL traffic for its own benefit or
        that of any other operator.

<PAGE>   5
13.   To guarantee not to cause any damage to the physical and technical
      infrastructure of OCCEL and also to respect the conditions stipulated by
      the Internal Work Rules, EMPZL being obligated to assume the costs of
      repair of the damage caused, provided that such damage is imputable to
      EMPZL or to its contractors.

14.   To permit access at any time to EMPZL facilities to the persons
      authorized by OCCEL in order to perform preventive and corrective
      maintenance of the equipment for which it is responsible.  OCCEL shall
      provide, with sufficient advance notice, a list of these persons, who must
      fulfill the conditions established in the EMPZL Internal Work Rules.  In
      the event that access for the persons designated by OCCEL were not
      possible, due to the absence of an EMPZL executive who authorizes it, the
      latter engages to permit such access in accordance with the terms and
      conditions agreed upon by the persons responsible for the management of
      this contract.

B.  ADMINISTRATIVE, ECONOMIC AND FINANCIAL:

BI.  IN RELATION TO BILLING

1.    EMPZL shall include in the bill for services to its subscribers the
      charges for calls which the consumers of its network originate to the
      OCCEL network, including access charges to the EMPZL PSTN and charges for
      usage of the OCCEL CTN.  The statement of calls and charges shall be that
      received from OCCEL on magnetic tape or any other media agreed upon.

      EMPZL may verify the statement of charges for access charges for its PSTN
      recorded by OCCEL against the statement for control and verification
      purposes which EMPZL recorded at its digital centers, in order to
      establish the difference of the charge units measured according to the
      agreed upon format. By mutual agreement between the parties, a percentage
      of difference shall be established as the permitted margin of tolerance

      In the event that the difference between the total amounts recorded by
      OCCEL and EMPZL exceeds the aforementioned margin of tolerance and there
      is no technical justification, the access charges shall be billed at the
      higher record, whether it corresponds to the information of OCCEL or of
      EMPZL.  In the event that there is technical justification, the billing
      shall be done based on the record which does not contain errors or by
      means of the combination of the information of OCCEL and EMPZL.

      The parties shall agree monthly upon the dates and times for cutting the
      billing period.  EMPZL may include in the same bill the charges for other
      items and even charges from the other cellular network operators.  The
      bill will contain the information pursuant to APPENDIX NO. 2 of this
      agreement. 
<PAGE>   6
The incremental costs due to inclusion on bills issued by EPMZL of the calls
made by the subscribers to its PSTN to the OCCEL CTN, will be chargeable to
OCCEL and will be paid in the manner set forth in APPENDIX NO. 2.

2.   To rebill the accounts including extra charge to the subscribers or
     users who have not paid the total amount of the OCCEL Cellular Mobile
     Telephone Service within the time limits stipulated to pay the bill.

3.   To maintain the records that could not be billed in each period
     (recycle) and are susceptible to be billed again in the next period, and
     submit a report of these amounts to OCCEL.  This point is applicable only
     in the cases in which subscribers are in the process of incorporation into
     the EPMZL subscriber files.  At maximum one (1) recycle will be permitted;
     after this recycle the records that had not been incorporated will be
     considered as inconsistencies with their respective justifications.

4.   Unless it has express and written authorization from OCCEL, EPMZL
     may in no case bill any charge or amount derived from the rendering of
     Cellular Mobile Telephone Service by OCCEL, other than that specified in
     this contract.

5.   To bill its subscribers or users for penalties or interest on late
     payment at the maximum rate legally accepted, pertaining to amounts that
     have not been collected within time limits stipulated on the bill, for
     calls transmitted to the OCCEL CTN.  These penalties or interest will be
     billed monthly for each month or fraction of delay and the form in which it
     shall be distributed shall be agreed upon by the executives responsible for
     the administration of this contract.  This penalty shall not apply in the
     event of an inevitable accident or force majeure.

6.   To submit to OCCEL though magnetic media or another procedure
     mutually agreed upon, the records of frauds and billing inconsistencies for
     calls from the PSTN to the CTN, with their justifications, and additionally
     those records which will be entered on the definitive list of accounts
     receivable, within fifteen (15) days following the end of every EPMZL
     billing period.

7.   To guarantee the integrity and quality of the billing of the calls
     originated on the EPMZL PSTN to the OCCEL CTN and to be responsible for
     errors generated in the billing process in relation to the customers and
     authorities when such errors are imputable to EPMZL.

BII.  IN RELATION TO COLLECTION OF CALLS ORIGINATED ON THE EPMZL PSTN

1.   EPMZL shall incorporate into the invoices which it issues for
     collection from its subscribers and users a tear-off or coupon which
     contains the total sum which corresponds to OCCEL for the use of its
     cellular.
<PAGE>   7
        network and for any other item which implies a debt in favor of OCCEL.
        This coupon must be designed in such a manner that the amount printed
        thereon can be deposited directly to the account of OCCEL by the cashier
        of the institution at which the bill is paid.  The characteristics of
        the aforementioned coupon shall be agreed upon by the executives
        appointed by the parties for the administration of this agreement.
        OCCEL shall bear the expenses for the procedures with the collection
        institutions and the amount which they charge for direct deposit to the
        account of OCCEL of the sums corresponding thereto.

2.      During the initial months of validity of this contract, EPMZL shall
        collect the amounts billed to its subscribers and users for the calls
        originated by them to the OCCEL CTN, transferring to OCCEL the portion
        corresponding to the fees for the use of its CTN and retaining for
        itself the amount of the access charges for the use of its PSTN.

        The aforementioned transfer shall take place within twenty-five (25)
        calendar days from the final payment date without surcharge established

        On the same date EPMZL shall deduct from the sum to be transferred to
        OCCEL the amounts which OCCEL owes thereto for liability for frauds and
        inconsistencies, access charges for calls originated by OCCEL
        subscribers, or any other sum which has been agreed upon in this
        contract, and which has been incurred in the billing period to which
        these transfers pertain.

        Within the fifteen (15) business days following the final date for
        payment without surcharge established for the EPMZL subscribers, the
        executives designated by parties shall reconcile the accounts in order
        to establish the net amount which must be transferred to OCCEL by EPMZL,
        or the amount which OCCEL owes to EPMZL, according to the result of the
        reconcilement of accounts.

        The provisions of this section shall be applicable until the date on
        which OCCEL has completed the necessary measures to perform the separate
        collections for which provision is made in the preceding section.  Once
        this condition is fulfilled, EPMZL and OCCEL shall execute an instrument
        to institute the separation of collections.

3.      Except as provided by Law, EPMZL shall not accept partial payments
        differentiated by telephone operator companies, that is, it shall
        require from its subscribers the payment in full of the telephone
<PAGE>   8
     service billed, and in the event of non-payment, it shall apply the Law,
     the regulations and this contract.

4.   EPMZL shall grant payment facilities to its subscribers or users
     when they so request and provided that they fulfill the internal rules
     established. These facilities shall only be applicable to amounts owed for
     calls to the OCCEL CTN when the latter indicates its approval thereof.  The
     manner in which the interest relating to the financing of these facilities
     shall be distributed shall be agreed upon by the executives responsible for
     the management of this agreement.

     The debit advices issued by EPMZL in order to grant the payment facilities
     specified herein, or to resolve claims which require such notes, shall not
     constitute a breach of the preceding provision when such notes have been
     submitted to OCCEL and are duly approved by the latter.

5.   EPMZL shall pay interest OCCEL on late payment at a rate equivalent
     to the maximum allowed by Commercial Law for similar transactions, monthly
     or proportional to the days elapsed from the demandability of the debt to
     the verification date, due to the delay in the payment of the amounts
     collected for the use of the OCCEL CTN.  Excluded from this sanction are
     the delays due to force majeure or inevitable accident.

6.   To maintain and continuously update the records of the active list
     of accounts receivable and also to issue bills in order to collect them.
     The management of recoveries on debtors in default shall be effected in
     accordance with the provisions of APPENDIX NO. 2.

7.   Until the separation of collections for which provision is made in
     number B.II.1 of the second clause, EPMZL shall remit to OCCEL, within the
     ten (10) calendar days subsequent to the final date for payment without
     surcharge established for its subscribers in the respective collection
     period, EPMZL shall submit to OCCEL through magnetic media or another
     procedure mutually agreed upon and according to the design agreed upon, the
     information as to amounts not collected, detailed in the same form as they
     were submitted by OCCEL for billing, as well as the cumulative amounts of
     the debt portfolio.

8.   EPMZL shall suspend access to the mobile telephone network of OCCEL
     to the subscribers requested by OCCEL by written notice, provided that it
     is technically possible and will not affect access to other networks,
     unless there is express written authorization from the operators which
     could be affected.

9.   To submit to OCCEL all documents that it requires and are within
     the scope of EPMZL to supply, in order that OCCEL may, under its own
     responsibility, proceed with legal collection of late payments.

     submitted to the other party, and is obliged to be liable to the other
     party, customers and authorities for errors generated in processes where
     such information is used, provided that such errors are imputable thereto.

3.   Each party must pay the sums which are owed to the other for calls which
     cannot be collected from the subscribers or users due to frauds and
     inconsistencies.  APPENDIX NO. 2 specifies the manner in which liability
     for these payments shall be determined.  Amounts due for frauds and
     inconsistencies shall be included within the monthly reconciliations.

4.   Liability to the subscriber:  In all of their relationships with the
     public, both EMPZL and OCCEL shall act governed by the principles of
     honesty, integrity, loyalty and service and shall not act in any manner
     which discredits, affects or damages the reputation of the other party in
     any way.  Both parties shall act in good faith, honestly and diligently,
     using their best efforts in order to guarantee subscriber satisfaction and
     the rendering of the services offered.

5.   Social responsibility:  In the interconnection and the execution of the
     agreement, the parties shall take into consideration the fact that their
     goal is the providing of telecommunication public services in the charge 
     of the State, in a continuous and efficient manner.

SIXTH CLAUSE - INTERCONNECTION LIMIT:

In order to limit the liability of the parties, the interconnection limit shall
be the general digital distributors or optical distributors of EMPZL centrals
directly connected with the OCCEL CTN, and in consequence every company must
assume the costs within its own network.

SEVENTH CLAUSE - SUBMISSION TO REGULATION:  The interconnection between the two
networks, is based upon the plans, regulations, definitions and standards of
the Ministry of Communications, and in the absence thereof, upon the plans,
definitions and standards of the International Telecommunications Union (ITU)
and other international bodies of jurisdiction, in which Colombia forms a part
by virtue of international agreements and covenants. 

EIGHTH CLAUSE - INTERCONNECTION DIMENSIONS:
The quality of the circuits required for different links or routes between two
networks, both for incoming and outgoing traffic, as well as the quantities for
future expansion, shall be calculated by OCCEL and reviewed by EMPZL and shall
be established according to instruments signed by the parties.  This
dimensioning will be reviewed at least every six months to adjust it to traffic
conditions.  The dates of entry into service of links for future extensions
shall be mutually agreed upon, taking into account that the grade of service
and development plans of each company may not be affected by the delay by one
party in the execution of such extensions.
<PAGE>   16
NINTH CLAUSE - RELIABILITY AND AVAILABILITY:  Both parties should maintain the
interconnection minimum levels of reliability in order to guarantee service
continuity.  The reliability shall be measured in terms of the time in which
the interconnection is normally operating.  The minimum reliability for the
subscriber to interconnection equipment is 99.99% measured over a monthly
period, which means that the total of system dropped times which affect the
whole interconnection, should not be higher than 4.4 minutes/month.  The
interconnection will have alternate routes as agreed upon by the parties.

TENTH CLAUSE - AUDITING:  Each party may directly or through a third duly
authorized party undertake the necessary review to establish account accuracy
and the faithful compliance with the procedures agreed upon by virtue of this
agreement.  The cost incurred for this purpose shall be paid by the party who
is reviewing.  The party whose accounts and procedures shall be reviewed must
provide all required facilities.

ELEVENTH CLAUSE - EXEMPTION FROM LIABILITY IN THE EVENT OF INTERRUPTION:
Neither party shall be liable in relation to the other party for damages

permit sufficient fulfillment of the obligations acquired by virtue of the
present contract.  The parties expressly declare that the transmission of such
information, either verbally or in writing, to third parties that are not duly
authorized to request and receive it will result in the full indemnity of
damage caused by this disclosure.

THIRTEENTH CLAUSE - DURATION OF AGREEMENT:  This agreement has a duration of
five (5) years from the date of its execution, and may be extended by equal
periods, as long as the parties do not issue notification to the contrary in

not possible and the Telecommunications Regulatory Commission does not have
jurisdiction to hear the differences, discrepancies or conflicts in question,
the parties jointly or individually shall submit themselves to decision by a
Court of Arbitration.

If the controversy, discrepancy or conflict were eminently technical in nature,
the parties by mutual agreement may submit it to the decision of two experts in
the subject matter which is the object of the difference, who shall be
designated by the ACIEM.  The decision of these experts shall be of mandatory
fulfillment by the parties.

The Court of Arbitration shall consist of three arbiters designated by mutual
agreement, who must be licensed, practicing attorneys, with knowledge of

parties, the designation of the arbiters shall be made by the Chamber of
Commerce of Manizales.  The judgment shall be by law and must take place within
six (6) months following the constitution of the Court.

The cost for the petition for the constitution and the operation of the Court
shall be paid by the parties in equal proportion.

aspects of the interconnection agreement.

     
<PAGE>   20
SECOND CLAUSE - DEFINITIONS:  EPMZL and OCCEL agree to the following
definitions for the terms related as follows:

SWITCHING EQUIPMENT FOR THE INTERCONNECTION:  All devices which are part of the
OCCEL MSC or EPMZL switching centers, and are directly connected with
transmission systems for the intercommunication between the two networks.

GRADE OF SERVICE:  Ratio by percentage between the quantity of unsuccessful
call attempts due to congestion or failure, and the total of call attempts

THIRD CLAUSE - CONNECTION POINTS AND ROUTING:  The parties agree that at the
beginning the interconnection points between EPMZL and OCCEL networks shall be
the EPMZL transmission center designated as Centro 3 and the OCCEL MSC located
in Pereira.  However, the executives designated by the parties to manage this
agreement may agree by means of a mutually executed instrument as to the
creation of other connecting points between their two networks, according to
traffic and quality of service requirements.

At the beginning, alternative routes to handle traffic between the EPMZL and
OCCEL networks will not be available.  However, the establishment of
alternative routes, through third party networks, may be agreed upon by means
of an instrument signed by mutual agreement of the executives designated by
parties to manage this agreement.

The parties agree that until such times as the MSC of OCCEL is operating in
Pereira, the interconnection shall be effected utilizing the MSC of OCCEL in
Cali.  For that provisional interconnection the TELECOM switched network shall

                                 APPENDIX NO. 2
                 FINANCIAL, ECONOMIC AND ADMINISTRATIVE ASPECTS

FIRST CLAUSE - OBJECT : The object of this Appendix is to supplement and
specify the procedures related to the financial, economic and administrative
aspects of the interconnecting agreement.

SECOND CLAUSE - INFORMATION INCLUDED IN THE BILL : The bill from EPMZL to its
subscribers, the information about calls originated by them to the OCCEL
cellular mobile telephone network, and the amount shall be presented in the
manner agreed upon by the parties agree within the thirty (30) days following
the concluding of this agreement.

THIRD CLAUSE - BILLING COSTS : OCCEL shall effect payment to EPMZL in the
amount of fifty ($50.00) pesos for each bill issued with calls to the OCCEL
network.  This amount includes all concepts related to detail billing of calls
to the OCCEL cellular network, and the collection of amounts owed by OCCEL
where applicable.

These billing costs will be readjusted annually in the same percentage as the
minimum wage increase, when it occurs.

FOURTH CLAUSE - LATE PAYMENT RECOVERY : According to the accounting system, the
list of late payments for calls made by EPMZL users to the OCCEL CTN shall be
borne by each company, according to the respective proportion.  The recovery of
late payments may be obtained by either OCCEL or EPMZL, according to the
agreement made between the parties.  In any case, each party will submit to the
other the documents required for legal collection of these late payments.

FIFTH CLAUSE - ATTENTION TO CLAIMS : OCCEL shall handle the claims relating to
the billing of the calls originated by the EPMZL subscribers to its CTN.  In
the claims which merit it, OCCEL and EPMZL shall conduct the pertinent
investigations, providing each other with the necessary technical and
operative support and sharing all information.

The parties shall agree as to the manner in which EPMZL shall report on the
procedures established by OCCEL for the handling of the claims, when the
subscribers or users of EPMZL or OCCEL go to the EPMZL customer service centers
to submit claims as to calls made to the OCCEL CTN.  In addition, EPMZL shall
supply information concerning the billing of the calls to the OCCEL cellular
network, when the aforementioned information is requested by the subscribers or
users of EPMZL or OCCEL at the EPMZL customer service centers.  In the event
that OCCEL so requests and it is physically available, EPMZL shall provide a
space at its facilities for the handling of claims concerning calls originating
from its PSTN to the OCCEL CTN; the parties shall agree as to the economic
conditions whereby EPMZL shall provide the aforementioned space.

SIXTH CLAUSE - ANALYSIS AND RECOVERY OF FRAUDS AND INCONSISTENCIES : An
inconsistency is considered to be all
<PAGE>   23
inaccurate information about data concerning the recording, payment or billing
of a call, which temporarily or permanently makes the billing process and the
charging of this call to the user who actually made it impossible.  There is
temporary impossibility of billing when the inaccuracy is solved after an
analysis which makes it possible to effect the billing in a subsequent period.
There is permanent impossibility when, after the respective analysis, it is
determined that respective charge cannot be collected.  Each party shall be
liable to the other for payment for the inconsistencies which arise due to
calls which originated on its network, unless it is proven that such
inconsistencies are imputable to inaccuracies or errors committed by the other
party, or to an irremediable technical problem.

It is considered that a fraud has been committed in a call when it has been
determined that collection definitively cannot be effected for reasons other
than the occurrence of an inconsistency or the declaration that the debt assumed
by the subscriber or user generating is impossible to collect. Fraudulent calls
can be made from OCCEL or EPMZL networks, whether the origin number has not been
assigned to any subscriber or user, the calls have never been billed to the
subscriber to whom the number of origin is assigned, or, having been billed,
they have been subsequently been deducted from the account of the subscriber to
whom the number of the origin is assigned.  Each party shall be liable to
the other for payment for the fraudulent calls originated in its network, unless
it is proven that the cause of such fraud is due to negligence or to errors
committed by the other party.

If within the three months subsequent to the date of the reconcilement in which
it was determined that there was a suspicion of fraud or inconsistency as to a
call, it has not been possible to determine whether a fraud or inconsistency
effectively occurred in that call, and therefore it has neither been possible
to determine the liability for the occurrence of either of those events nor to
collect the charges for the call from any subscriber or user, the party
operating the network on which the call originated shall assume liability in
relation to the other for the payments which are to be made.

SEVENTH CLAUSE - BALANCE CONFRONTATION AND RECONCILING OF ACCOUNTS;  EPMZL and
OCCEL shall maintain an accounting control which shall be reconciled monthly in
order to determine the net balance which the debtor party must pay to the
creditor party.  The dates for these reconcilings of accounts shall be agreed
upon by the executives responsible for the management of the agreement.  For the
effects of the reconciliation, parties may agree to offset accounts for the
leasing of systems and transmission media lease, leasing of facilities for
equipment location, leasing of electric and air conditioning infrastructure,
billing costs, payment for frauds and inconsistencies, interest on late payment
and any other concept related to the execution of this agreement.

acting as the General Manger and Legal Representative of EMPRESAS PUBLICAS DE
PEREIRA, Public Entity of Municipal Order, who hereinafter will be referred to
as EE.PP., this interconnection agreement is concluded and shall be governed
pursuant to the clauses within this document, subject to the following
considerations and definitions:

CONSIDERATIONS:

FIRST.  OCCEL is the awardee of the concession which has as its object the
rendering of a Cellular Mobile Telephone Service on the "A" network in the
Western region of Colombia pursuant to agreement 000005/94 concluded between it
and the Ministry of Communications on March 28, 1994.

SECOND.  The Law 37 of 1993 and the Decree 741 of the same year authorized the
access right of the Cellular Mobile Telephone operators (CTN) to the public
switched telephone networks (PSTN) already established in the country, for the
interconnection of the elements of their networks and to manage traffic, and
also stipulating the obligation of the public switched telephone network
operators to guarantee the access to their Mobile Switched Centers (MSC),
providing the facilities for the location of interconnection equipment within
equipment rooms of these centrals as well as the facilities of AC power supply
and access of the personnel of OCCEL S.A. for preventive and corrective
maintenance. 

THIRD.  Interconnection will be subject to the equal access principle -
pursuant to article 66 Decree 741 of 1993 by virtue whereof the MSC operators
are obliged to provide interconnection under equal technical and economic
conditions to every CTN operator.

FOURTH.  By means of Resolution 002 of 1993, the Telecommunications Regulatory
Commission established that for a one (1) year term from October thirteenth
(13th) of 1993, the fee for the interconnection between the PSTN subscriber
terminal and the local switching center will be TWENTY-FOUR ($24) Colombian
pesos per minute, for both outgoing calls and incoming calls to the PSTN.  This
tariff was established based on the variables of cost per line, percentage of
line usage, operation costs, maintenance and management per line per year, line
traffic per year, the useful life of the equipment and network, the replacement
thereof and the rate of discount or reasonable profit to the PSTN operator.
Furthermore, by means of Resolution 004 of 
<PAGE>   2
1993 issued by the Telecommunications Regulatory Commission, the principle was
established whereby the party calling to or from cellular network must assume
the costs thereof.

INTERCONNECTION AGREEMENT BETWEEN SOCIEDAD OCCIDENTE Y CARIBE - CELULAR S.A.
AND EMPRESA DE TELECOMMUNICACIONES DE ARMENIA - TELEARMENIA

Between the undersigned, GILBERTO ECHEVERRI MEJIA, resident of Medellin, with
citizens card number 3.302.711 of Medellin, who is acting as the president and
Legal Representative of OCCIDENTE Y CARIBE CELULAR, S.A. - OCCEL S.A. - a mixed
economy society with private capital in the majority, domiciled in Pereira,
that for the effects of this agreement will be referred to as OCCEL on one
part, and on the other part RUBEN DARIO CARCIA RODRIGUEZ, resident of Armenia,
identified with citizens card number 7'534.244 of Armenia, who is acting as the
General Manager and Legal Representative of the Empresa de Telecomunicaciones
de Armenia - TELEARMENIA -, an industrial and commercial company of national
order, who hereinafter will be referred to as TELEARMENIA, this interconnection
agreement is concluded and shall be governed pursuant to the clauses within
this document, subject to the following considerations and definitions:

CONSIDERATIONS:

FIRST.  OCCEL is the awardee of the concession which has as it object the
rendering of a Cellular Mobile Telephone Service on the "A" network in the
Western region of Colombia pursuant to agreement 000005 concluded with the
Ministry of Communications on March 28, 1994.

SECOND.  The Law 37 of 1993 and the Decree 741 of the same year authorized the
access right of the Cellular Mobile Telephone operators (CTN) to the public
switched telephone networks (PSTN) already established in the country, for the
interconnection of the elements of their networks and to manage traffic, and
also stipulating the obligation of the public switched telephone network
operators to guarantee the access to their Mobile Switched Centers (MSC),
providing the facilities for the location of interconnection equipment within
equipment rooms of these centrals and, at the same time, the facilities of AC
power supply, preventive and corrective maintenance, and also the other
facilities that are technically and administratively required, all at the
expense of the Cellular Mobile Network Operator.  

THIRD.  Interconnection will be subject to the equal access principle -
pursuant to article 66 Decree 741 of 1993 by virtue whereof the MSC operators
are obliged to provide interconnection under equal technical and economic
conditions to every CTN operator.

FOURTH.  By means of Resolution 002 of 1993, the Telecommunications Regulatory
Commission, exercising the powers conferred upon it by Decree 2122 of 1992,
established that for a one (1) year term from October thirteenth (13th) of
1993, the fee for the interconnection between the PSTN subscriber terminal and
the local switching center will be TWENTY-FOUR ($24) Colombian pesos per
minute, for both outgoing calls and incoming calls to the PSTN.  This tariff
was established based on the variables of cost per line,
<PAGE>   2
percentage of line usage, operation costs, maintenance and management per

2.      To acquire, install, operate, maintain, and replace the equipment and
        elements required in its network for the interconnection of its
        telephone system with the OCCEL CTN in order to guarantee that incoming
        and outgoing traffic can be transmitted according to the development
        plans of both companies, and in the quantity which guarantees that in
        the circuits interconnecting the
<PAGE>   4
        TELEARMENIA PSTN centrals with the OCCEL MSC in Pereira, call drops with
        automatic access will not exceed one (1%) percent in peak hours,
        excluding losses due to the equipment located between the TELEARMENIA
        subscriber and the TELEARMENIA switching center directly interconnected
        with the MSC of OCCEL.

3.      To permit all of the TELEARMENIA subscribers whose "A" subscriber number
        can be automatically identified and transmitted, to have access to the
        OCCEL cellular mobile telephone service, to the customer service
        provided by OCCEL, and also to the new services rendered to third
        parties through the OCCEL CTN, in accordance with the provisions of the
        Law and the agreement between the parties.  TELEARMENIA shall permit
        access to the CTN of OCCEL for all of its subscribers, but shall have
        the right to withdraw it for those who specifically so request and
        provided that this is technically feasible.

4.      To perform maintenance, both preventive and corrective, of the systems
        and transmission media belonging to TELEARMENIA and used by OCCEL under
        lease. The tariff agreed to by the parties for the leasing of these
        systems and media includes the respective maintenance cost. 

5.      To perform maintenance which guarantees, in incoming and outgoing
        traffic, a ratio of unsuccessful calls (with a technical failure)
        attributable to TELEARMENIA in relation to the total of calls offered in

        enhancement program or its configuration.  To test quality of service
        between the two networks and to perform maintenance programs,
        TELEARMENIA will provide to OCCEL two telephone lines with the nature of
        test numbers and which shall be exempt from payment of connection fees
        and basic charges.  These lines will have access to national long
        distance and cellular telephone service.  In the calls which are made
        from these lines to the test numbers agreed upon by the parties, OCCEL
        shall be exempt from payment of the interconnection fee in favor of
        TELEARMENIA but shall pay the charges which correspond to the use of
        other networks.  OCCEL shall pay all charges for calls made from these
        lines to subscribers other than the test numbers agreed upon by the
        parties.  When considered necessary, the tests shall be performed
        jointly following a previously agreed upon program. 

7.      To submit to OCCEL all the required information to guarantee that

8.      To verify monthly, or upon the request of OCCEL, the correct operation
        of its outgoing and incoming links, immediately notifying OCCEL of any
        damage.

9.      To adopt all measures in order to prevent fraud and generation of
        inconsistencies.  By virtue of this obligation, TELEARMENIA shall adopt
        the necessary measures order to prevent the access to OCCEL's CTN
        telephones without charge, not assigned, interrupted, retired and non
        intelligent public phones.  Access shall be permitted only to public and
        semi-public telephones and which have the ability to charge for this
        type of calls, which must be connected to centrals with the ability to
        identify the "A" subscriber number.

10.     TELEARMENIA must submit to OCCEL the identification number of the "A"
        subscriber who originates the call at the centrals of its PSTN.

11.     To repair, within the terms and conditions established by the executives
        responsible for the management of the contract, the failures reported by
        OCCEL.

12.     Not to differentiate the OCCEL traffic for its own benefit or that of
        any other operator.

13.     To guarantee not to cause any damage to the physical and technical
        infrastructure of OCCEL and also to respect the conditions stipulated by
        the Internal Work Rules, TELEARMENIA being obligated to assume the costs
        of repair of the damage caused, provided that such damage is imputable
        to TELEARMENIA or to its contractors.

14.     To permit access at any time to TELEARMENIA facilities to the persons
        authorized by OCCEL in order to perform preventive and corrective
        maintenance of the equipment for which it is responsible.  OCCEL shall
        provide, with sufficient advance notice, a list of these persons, who
        must fulfill the conditions established in the TELEARMENIA Internal Work
        Rules.  In the event that access for the persons designated by OCCEL
        were not possible, due to the absence of an TELEARMENIA executive who
        authorizes it, TELEARMENIA engages to permit the access in accordance
        with the terms and conditions agreed upon by the persons responsible for
        the management of this contract.

B.  ADMINISTRATIVE, ECONOMIC AND FINANCIAL:

II.  IN RELATION TO BILLING

1.      TELEARMENIA shall include in the bill for services to its subscribers or
        users the charges for calls which the consumers of its network originate
        to the OCCEL network, including access charges to the TELEARMENIA PSTN
        and charges for usage of the OCCEL CTN.  The 
<PAGE>   6
        statement shall be received from OCCEL on magnetic tape or any other
        media agreed upon by the parties.

        TELEARMENIA may verify the statement of charges for access charges to
        its PSTN submitted by OCCEL against the statement for control and
        verification purposes which TELEARMENIA makes, based on calls recorded
        in their digital centrals, to establish the difference of the charge
        units assessed according to the agreed upon format.  By mutual agreement
        between the parties, a percentage of difference shall be established as
        the maximum tolerance permitted.

        In the event that the aforementioned difference exceeds the maximum
        tolerance established, and there is no technical justification, the
        access charges shall be billed according to the higher records, whether
        the information corresponds to OCCEL or to TELEARMENIA.  If there is a
        technical justification, the billing shall be according to the
        information which is without errors, or by means of the combination of
        the OCCEL and TELEARMENIA information.

        The parties shall agree monthly upon the dates and times for cutting the
        billing period.  TELEARMENIA may include in the same bill the charges
        for other items and even charges from the other cellular network
        operators.  The bill will contain the information pursuant to APPENDIX
        NO. 2 of this agreement.

2.      To rebill the accounts including extra charge to the subscribers or
        users who have not paid the total amount of the OCCEL Cellular Mobile
        Telephone Service within the time limits stipulated to pay the bill.

3.      To maintain the records that could not be billed in each period
        (recycle) and are susceptible to be billed again in the next period, and
        submit a report of these amounts to OCCEL.  The executives responsible
        for the billing at TELEARMENIA and at OCCEL shall jointly define the
        number of periods during which the unbilled records will be recycled,
        with the objective of the billing of each call actually made by a
        subscriber or user of TELEARMENIA.  When the impossibility of billing a
        call is established, it shall be treated as a definitive inconsistency
        with its appropriate justification.

4.      Unless it has express and written authorization from OCCEL, TELEARMENIA
        may in no case bill any charge or amount derived from the rendering of
        Cellular Mobile Telephone Service by OCCEL other than that indicated in
        this agreement.

5.      To bill its subscribers or users for penalties or interest on late
        payment at the maximum rate legally accepted, pertaining to amounts that
        have not been collected within time limits stipulated on the bill, for
        calls transmitted to the OCCEL CTN.  These penalties or interest will be
        billed monthly for each
<PAGE>   7
     month or fraction of delay and shall correspond TELEARMENIA so long as
     that institution is responsible for a percentage of the sums billed in the
     terms established in number B.II.1 of the second clause.  If reconcilements
     of accounts are effected on the sums collected, this interest shall be
     distributed in the manner agreed upon by the executives responsible for the
     administration of this contract.  This penalty shall not apply in the event
     of any inevitable accident or force majeure, or in those cases specifically
     established in the legislation in force.

 6.  To submit to OCCEL though magnetic media or another procedure
     mutually agreed upon, the records of calls not billed, the records of calls
     pending payment which were billed and the records of frauds and billing
     inconsistencies for calls from the PSTN to the CTN, with their
     justifications, and additionally those records which will be entered on the
     definitive list of accounts receivable, within eight (8) days following the
     end of every TELEARMENIA billing period.

7.   To guarantee the integrity and quality of the billing of the calls
     originated on the TELEARMENIA PSTN to the OCCEL CTN and to be responsible
     for errors generated in the billing process in relation to the customers
     and authorities when such errors are imputable to TELEARMENIA.

II.  IN RELATION TO THE TRANSFER OF THE SUMS CORRESPONDING TO THE USE OF THE
OCCEL CELLULAR NETWORK

1.   From the total of the sums paid for the use of the OCCEL cellular
     network in the record which OCCEL must deliver on a monthly basis to
     TELEARMENIA for the purposes of the billing of the calls made to its
     cellular network by the TELEARMENIA subscribers and users, deduction shall
     be made of the sums corresponding to the use of the cellular network in the
     calls which cannot be billed because they present inconsistencies which
     definitively cannot be billed, and deduction shall be made of the sums
     corresponding to calls between test numbers which the parties have agreed
     to establish as exempt from payment.  To this result shall be added the sum
     for the use of the cellular network corresponding to the inconsistencies
     which, having been deducted in previous periods, could be billed on recycle
     in the respective billing period. The sum total thus obtained constitutes
     the total sum billable to the subscribers and users of TELEARMENIA for the
     use of the OCCEL cellular network, that is, the total sum which can be
     collected by TELEARMENIA.

     TELEARMENIA shall be liable to OCCEL for 86.5% of the aforementioned total
     sum billable, and in turn everything collected for the billing for the use
     of the cellular network of OCCEL, plus the financial yield which
     TELEARMENIA may obtain on these sums during the period comprised between
     the date of collection and the date of transfer of the aforementioned
     86.5%, plus the 
<PAGE>   8
collections of penalties and interest on late payment which TELEARMENIA charges
to its users on these amounts shall correspond to TELEARMENIA.  The difference
which results between the income corresponding the TELEARMENIA which has just
been enumerated and the 86.5% of the total billable amount for which
TELEARMENIA shall be liable shall cover the services of billing and collection
rendered by TELEARMENIA and the amount of the accounts which finally are
considered uncollectible by TELEARMENIA.

Within the fifteen (15) calendar days following the date of each billing
process, the parties who sign this contract shall effect the reconcilement of
accounts corresponding to the billing which has just taken place.  The
aforementioned reconcilement shall establish the amount which corresponds to
the 86.5% of the total amount billable for the use of the OCCEL cellular
network, to which shall be added the other sums which correspond to OCCEL for
any other item related to the services rendered by OCCEL between the first and
last day of the month preceding that in which the reconcilement is effected.
From the aforementioned sums in favor of OCCEL, deduction shall be made of the
total of the sums in favor of TELEARMENIA for the interconnection fee paid on
the calls which were made by the OCCEL subscribers and users to the TELEARMENIA
network during the same period of consumption for which the sums corresponding
to the calls made by the TELEARMENIA users to the OCCEL network are being
reconciled; the rents for the leasing of infrastructure owned by TELEARMENIA
which may have been leased to OCCEL, incurred between the first and last day of
the month preceding that in which the reconcilement is effected; and deduction
shall be made for any other item in favor of TELEARMENIA agreed upon in this
contract and which may have been incurred between the first and last day of the
month preceding that in which the reconcilement is effected.  As a result of
the reconcilement determination shall be made of the net sum in favor of one of
the parties, which must be transferred by the debtor party to the creditor
party within the fifteen (15) calendar days subsequent to the date on which the
reconcilement is effected.

In the event that a reconcilement of accounts is delayed due to reasons
imputable to the debtor party, as of the fifteen (15) calendar days subsequent
to the final date for the effecting of the reconcilement which was stipulated
in the preceding paragraph, the debtor party shall pay the creditor party, for
the delay in the payment of the sums in favor of the creditor party, an
interest on late payment at a rate equivalent to the maximum permitted by
commercial law for similar transactions, monthly or proportionately to the
number of days of delay which have elapsed.

For the purposes of preparation of the reconcilement of accounts based upon a
percentage of the total billable amount, TELEARMENIA shall remit to OCCEL,
within the 

<PAGE>   9
eight (8) calendar days subsequent to the date on which each billing process
has taken place, the following information relating to calls made by the
TELEARMENIA subscribers to the OCCEL cellular network and corresponding to the
period and the figures which are going to be reconciled:

The record of the calls not billed due to the presentation of definitive
inconsistencies; the total amount of the accounts pending payment which were
billed, with their corresponding maturity periods; the record of calls with
inconsistencies which, having been considered definitive, could be clarified
and were billed after the recycle; the record of accounts which ceased to be
billed upon passage to definitive accounts receivable; the record of accounts
receivable which are five months old, and the total amount collected and not
collected.  These records shall have the same record format as the calls to be
billed which is delivered by OCCEL and shall be delivered by TELEARMENIA on
diskette, magnetic tape or any other media which permits automatic processing,
as agreed upon by the parties. 

In each reconcilement calculation shall be made of the percentage ratio between
the sums billed for the first time five months past and which TELEARMENIA has
still not collected, and the total amount billable for the use of the cellular
network of OCCEL associated with the billing period of five months past.  The
aforementioned percentage shall be considered as the percentage of the
portfolio of doubtful collection associated with the billing period of five
months past.  TELEARMENIA shall be liable for the entirety of this portfolio of
doubtful collection when it, calculated as indicated herein, does not exceed
8.5% of the total billable amount associated with the billing period of five
months past; the sums which exceed this 8.5% shall be paid to TELEARMENIA by
OCCEL in the reconcilement of accounts in which the respective calculation is
made.  In the event that TELEARMENIA is subsequently able to recover sums
corresponding to this portfolio of doubtful collection, TELEARMENIA shall
repay 80% of the amount recovered to OCCEL.  The aforementioned repayments
shall take place until 80% of the total of the amounts which OCCEL may have
paid to TELEARMENIA in relation to the portfolio of doubtful collection is
attained.

The provisions made in this agreement both as to the liability of TELEARMENIA
for the total billable amount (86.5%) as well as that stipulated herein as the
maximum amount of the portfolio of doubtful collection for which OCCEL shall be
liable (8.5%) are figures subject to review upon the request of OCCEL or
TELEARMENIA which may be made at the end of each semiannual term of validity of
this contract.  In the event that either of the parties requests the
aforementioned review, agreement shall be made as to new percentages for the
figures which have been
<PAGE>   10


indicated herein.  In the event that the parties are unable to reach an
agreement as to the new percentages which must apply for the aforementioned
figures, the effecting of the transfers of the sums corresponding to the use of
the OCCEL cellular network based upon a percentage of the total billable amount
shall cease, and as of that time the reconcilements of accounts shall continue
to be effected on the basis of the sums actually collected by TELEARMENIA and in
accordance with the procedure agreed upon by the parties.  In this case the
following stipulations shall be observed:

The reconcilements of accounts shall take place within the first fifteen (15)
calendar days of each month and the period of reconcilement shall be the
immediately preceding calendar month.  In order to effect the reconcilement, the
amount which may have been collected by TELEARMENIA during the reconcilement
period for the fee corresponding to the use of the OCCEL cellular network shall
be established; to this sum shall be added the other sums which correspond to
OCCEL for any other item relating to the series rendered by OCCEL during the
reconcilement period.  From the aforementioned sums in favor of OCCEL, deduction
shall be made of the amount of the sums in favor of TELEARMENIA for the
interconnection fee on the calls which may have been made by the OCCEL
subscribers and users to the TELEARMENIA network during the consumption period
for which the collections which are the object of the reconcilement were
effected; deduction shall be made of the rents for the leasing of infrastructure
owned by TELEARMENIA which may have been leased to OCCEL, incurred during the
reconcilement period; deduction shall be made of the amount of the claims
accepted from TELEARMENIA users during the reconcilement period; deduction shall
be made for billing and collection services, taking into account the amount
which is established in APPENDIX NO. 2 to this contract; and deduction shall be
made for any other item in favor of TELEARMENIA agreed upon in this contract and
which may have been incurred during the period for which the reconcilement is
effected (other than the 13.5% of the total billable amount, which will not
correspond to TELEARMENIA when accounts are reconciled on the basis of the sums
actually collected).  As a result of the reconcilement, determination must be
made of the net balance in favor of one of the parties, which must be
transferred by the debtor party to the creditor party within the fifteen (15)
calendar days following the date on which the reconcilement was effected.

In the event that a reconcilement of accounts is delayed due to reasons
imputable to the debtor party, as of the fifteen (15) calendar days subsequent
to the final date for the effecting of the reconcilement which was stipulated in
the preceding paragraph, the debtor party shall pay the creditor party, for the
delay in the payment of the sums in favor of the creditor party, and interest on
late payment at a rate equivalent to the
<PAGE>   11
        maximum permitted by commercial law for similar transactions, monthly or
        proportionately to the number of days of delay which have elapsed.

        For the purposes of preparation of the reconcilement of accounts based
        upon a percentage of the total billable amount, TELEARMENIA shall remit
        to OCCEL, within the first eight (8) calendar days of each month, the
        following information relating to calls made by the TELEARMENIA
        subscribers to the OCCEL cellular network and corresponding to the
        period and the figures which are going to be reconciled:

        The record of the calls not billed due to the presentation of temporary
        or definitive inconsistencies; the record of the accounts pending
        payment which were rebilled, with their corresponding maturity periods;
        the record of calls with temporary or definitive inconsistencies which
        could be clarified and were billed after the recycle; the record of
        accounts which could not be rebilled in recycle; the record of accounts
        which ceased to be billed upon passage to definitive accounts
        receivable, and the total amount collected and not collected.  These
        records shall have the same record format as the calls to be billed
        which is delivered by OCCEL and shall be delivered by TELEARMENIA on
        diskette, magnetic tape or any other media which permits automatic
        processing, as agreed upon by the parties. 

2.      Except as stipulated by law, TELEARMENIA shall ensure that its
        subscribers and users pay the entirety of the sums in favor of OCCEL
        included in its bills, that is, TELEARMENIA shall require its
        subscribers and users to effect payment in full for the sum billed
        therefor, and in the case of non payment, it will apply the Law, the
        regulations and this contract. 

3.      TELEARMENIA shall grant payment facilities to its subscribers or users
        when they so request and provided that they fulfill the internal rules
        established.  While TELEARMENIA is responsible for a percentage of the
        amounts billed, in the provisions set forth in number B.II.1 of the
        second clause, this entity shall be autonomous for the purpose of
        granting to its subscribers facilities for payment for sums in favor of
        OCCEL, and the entirety of the interest derived from such facilities
        shall correspond thereto.  In the event that reconcilements of accounts
        are effected on the basis of the sums in favor of OCCEL collected by
        TELEARMENIA, these facilities shall only be applicable to the sums owed
        for calls to the OCCEL CTN when OCCEL indicates its approval in this
        sense; the manner in which the interest relating to the financing of
        these facilities shall be distributed shall be agreed upon by the
        executives responsible for the administration of this agreement. 

        The credit notes issued by TELEARMENIA in order to grant the payment
        facilities specified herein, or to

<PAGE>   12
      resolve claims which require such credit notes, shall not constitute a
      breach of the preceding provision when such notes have been submitted to
      OCCEL and are duly approved by the latter.

4.    TELEARMENIA shall pay interest to OCCEL on late payment at a rate
      equivalent to the maximum allowed by Commercial Law for similar
      transactions, monthly or proportional to the days elapsed from the
      demandability of the debt to the verification date, due to the delay in
      the payment of the amounts collected for the use of the OCCEL CTN.
      Excluded from this sanction are the delays due to force majeure or
      inevitable accident.

5.    To maintain and continuously update the records of the active list of
      accounts receivable and also to issue bills in order to collect them.  The
      management of recoveries on debtors in default shall be effected in
      accordance with the provisions of APPENDIX NO. 2. 

6.    TELEARMENIA shall suspend the access to the mobile cellular telephone
      network of OCCEL for those subscribers which are requested by the latter
      in writing, provided that this is technically possible and does not affect
      the access to other networks, unless express authorization is given by the
      operators who could be affected.

7.    To submit to OCCEL all documents that it requires and are necessary in
      order that OCCEL may, under its own responsibility, proceed with legal
      collection of late payments, provided that the supply of these documents
      is within the scope of TELEARMENIA.

III.  IN RELATION TO SUBSCRIBER CLAIMS:

      Claims from TELEARMENIA subscribers related to calls to the OCCEL mobile
      telephone network shall be handled pursuant to APPENDIX NO. 2.  

IV.  IN RELATION TO PUBLICATION IN THE TELEPHONE DIRECTORY:

      In the event that OCCEL reaches an agreement with the company which

      agreed upon between OCCEL and the company which published the
      aforementioned directory without implication of either economic benefit
      for TELEARMENIA or expenditure on the part of that entity.

THIRD CLAUSE - OBLIGATION OF OCCEL:  OCCEL engages to fulfill the following
technical, administrative, economic and financial obligations.

A. TECHNICAL:
<PAGE>   13
1.      To guarantee the interconnection of its equipment with that of the
        public switched telephone network of the TELEARMENIA for both outgoing
        and incoming traffic.

2.      To acquire, install, operate, maintain and replace the required
        devices and equipment for interconnection of the OCCEL CTN with the
        TELEARMENIA PSTN, including those which permit the assessing of charges
        for outgoing and incoming calls, with specifications according to the
        development plans from both companies, and in the amount which
        guarantees a loss no greater than one percent (1%) during peak hours.
        This obligation to acquire the interconnection devices and equipment
        shall be understood as fulfilled when by agreement between the parties,
        such devices and equipment are provided by TELEARMENIA by lease.

3.      To permit all of the OCCEL to have access to the TELEARMENIA public
        switched telephone network, as well as to the new services rendered to
        third parties through the TELEARMENIA PSTN, in accordance with the
        provisions of the Law and the agreement between the parties.  OCCEL
        shall permit access to the PSTN of TELEARMENIA for all of its
        subscribers, but shall have the right to withdraw it for those who
        specifically so request.

4.      To perform both preventive and corrective maintenance of systems and
        transmission media owned by OCCEL which participate in the
        interconnection.

5.      To perform maintenance which guarantees, in incoming and outgoing
        traffic, a ratio of unsuccessful calls (with technical failure)
        attributable to OCCEL in relation to the total of calls generated in low
        traffic, which shall not exceed, on the average, three (3%) percent.

6.      To perform pursuant to APPENDIX NO. 1, measurements of traffic, grade of
        service, and in general, all tests which permit the establishment of the
        communications quality level between the two networks, and at the same
        time to identify the need to make adjustments in the interconnection
        enhancement program or its configuration.  To test quality of service
        between the two networks and to perform maintenance programs, OCCEL will
        provide to TELEARMENIA two telephone lines which shall have the nature
        of test numbers and which shall be exempt from payment of connection
        fees and basic charges.  These lines shall have access to national long
        distance and cellular telephone service.  In the calls which are made
        from these telephones to the test numbers agreed upon by the parties,
        TELEARMENIA shall be exempt from all payment. TELEARMENIA shall pay all
        of the charges for calls made from these lines to customers other than
        the test numbers agreed upon by the parties.  The location, the types of
        tests to be conducted and the time of usage of the lines and of the
        telephones which have the nature of test numbers delivered by one party
        to the other shall be agreed
<PAGE>   14
     upon by the executives designated by the parties for the administration of
     this agreement.  When considered necessary, the tests shall be conducted
     jointly according to a previously agreed upon schedule.

     In order to control the interconnection between the two networks, OCCEL and
     TELEARMENIA, within two (2) months after concluding this agreement, will
     make an emergency plan and a schedule for preventive maintenance, grade and
     quality of service measurements and evaluation of performance of

     operation of its outgoing and incoming links, immediately notifying
     TELEARMENIA of any damage.

9.   To adopt all required measures in order to avoid fraud on the
     TELEARMENIA PSTN.  In any case, OCCEL must be responsible for access
     charges generated from its CTN to the TELEARMENIA PSTN.

10.  In the event that OCCEL decides to install alternative transmission
     media to those installed by TELEARMENIA, OCCEL shall be responsible for the
     respective maintenance.

11.  To maintain the Ministry of Communications authorizations in force
     for the OCCEL radio link systems which are part of the interconnection and
     to pay the usage rights for the electromagnetic spectrum frequencies which
     these require.

12.  To repair failures reported by TELEARMENIA within the conditions
     and terms agreed upon by the executives responsible for the administration
     of the agreement.

13.  Not to differentiate the TELEARMENIA traffic for its own benefit
     or that of any other operator.

14.  To guarantee that it will not cause damage to the physical and
     technical infrastructure of TELEARMENIA, and also will respect the
     conditions established in its Internal Work Rules.  OCCEL shall be
     responsible for payment for all repair of damages caused, provided that
     such damage is reputable to OCCEL or it contractors.

B.  ADMINISTRATIVE AND FINANCIAL

I.  IN RELATION TO BILLING

1.   To supply to TELEARMENIA, in accordance with the provisions of
     number B.II.1 of the second clause, all of the information necessary in
     order that TELEARMENIA may bill the calls made by the TELEARMENIA PSTN
     users may bill the calls made by the TELEARMENIA PSTN users to the OCCEL
     CTN.  This information will be provided on 
<PAGE>   15
      a monthly basis within the seven (7) calendar days following the date
      agreed to by the parties as the billing closing date.

      If OCCEL, due to facts imputable to it, does not effect timely submission
      of the information necessary in order to bill the PSTN subscribers,
      TELEARMENIA will prepare the bill, without including that which pertains
      to the information that is not supplied by OCCEL in a timely manner.  The
      information that has not been processed will be included in the next
      billing period. In this case, OCCEL shall pay to TELEARMENIA, for the
      month or fraction thereof, interest on late payment at a rate equivalent
      to the maximum allowed by law for similar commercial transactions, on the
      amount of access charges that have not been collected by TELEARMENIA.
      Excluded from this sanction is non-fulfillment due to force majeure or
      inevitable accident. 

2.    OCCEL shall provide to TELEARMENIA, if it so requires, the information
      necessary in order to verify the payment of charges for access to its
      PSTN.

3.    To guarantee integrity and quality of records submitted to TELEARMENIA for
      billing and to be liable in relation to the customers and authorities for
      the errors generated in processes where this information is used, when 
      such errors are imputable to OCCEL.

4.    In the event that the parties decide to effect reconcilements of account
      based on the sums collected by TELEARMENIA, OCCEL shall credit and pay to
      TELEARMENIA the amount which corresponds to the increase in its expenses
      for processing, stationery, printing and collection - when applicable -
      incurred for the billing of the calls originating from its subscribers to
      the OCCEL CTN, in accordance with the provisions of APPENDIX NO. 2.  While
      the parties effect reconcilements of accounts based upon a percentage of
      the total billable amount, it is understood that the costs for billing and
      collection are included within the margin that will correspond to
      TELEARMENIA, and therefore it will not be necessary for OCCEL to make
      separate payment to TELEARMENIA for the costs of billing and collection.

II.  IN RELATION TO INTERCONNECTION TARIFFS AND OTHER INCOME GENERATED IN FAVOR
OF TELEARMENIA:

1.    To credit and pay TELEARMENIA on a monthly basis access charges incurred
      for calls originated from the OCCEL CTN to the TELEARMENIA PSTN, pursuant
      to the terms of Law 37 of 1993, Decree 741 of 1993 and Resolutions Nos.
      002 and 004 from the Telecommunications Regulatory Commission.  Such
      access charges shall be calculated based on TELEARMENIA and OCCEL records
      and applying to them a procedure similar to number B.I.1 of the second
      clause of this agreement. The payment of such charges shall be effected
      through the deduction that TELEARMENIA shall make from the 
<PAGE>   16
      amount owed to OCCEL for the use of its CTN during the same period in
      which access charges indicated herein were incurred.  

2.    To effect payment to TELEARMENIA of interest on late payment at a rate
      equivalent to the maximum allowed by commercial law for similar
      operations, monthly or proportionately to days which have elapsed from the
      due date of payment to the date on which this payment is verified, for the
      delay in the payment of amounts in favor of TELEARMENIA and which
      TELEARMENIA has not been able to deduct from the amount owed to OCCEL for
      payments for the use of its CTN.  Excluded from this sanction are the
      delays caused by force majeure or inevitable accident.  

3.    To credit and pay TELEARMENIA the respective costs of the use of the
      transmission media and systems for the interconnection provided by
      TELEARMENIA by lease.  The rent shall include the respective equipment 
      maintenance.  The amounts established by TELEARMENIA for these rents 
      shall be those stipulated in APPENDIX NO. 3.

4.    To credit and pay to TELEARMENIA the costs for usage of assigned physical
      space, usage and supervision of buildings, towers and air conditioning and

specify the procedures relating to the financial, economic and administrative
aspects of the interconnection agreement.

SECOND CLAUSE - INFORMATION INCLUDED IN THE BILL:  The bill from TELEARMENIA to
is subscribers, the information about calls originated by them to the OCCEL
cellular mobile telephone network, and the amount shall be presented as follows:

In the principal body of the bill notation shall be made separately of the
total amounts for the use of the OCCEL cellular network and the total amounts
for the interconnection fee which corresponds to TELEARMENIA.  On an attached
page there shall be a breakdown of each of the calls directed to the OCCEL
cellular network, in the forma which shall be agreed upon by the parties, which
shall contain at minimum the cellular number called, the duration and the
amount for the call.

THIRD CLAUSE - BILLING COSTS:  While the parties effect reconcilements of
accounts based upon a percentage of the total billable amount, as stipulated in
point B.II.1 of the second clause of this contract, it is understood that the
costs of billing and collection are included within the margin which will
correspond to TELEARMENIA, and therefore it will not be necessary for OCCEL to
effect separate payment to TELEARMENIA for billing and collection expenses.

In the event that the parties decide to effect reconcilements of accounts based
on the sums collected by TELEARMENIA, OCCEL shall credit and pay to TELEARMENIA
the amount of ninety-two ($92) pesos for each bill by TELEARMENIA with calls to
the OCCEL cellular network.  This amount includes all concepts related to the
processing of data and the printing of the principal body and the call
breakdown pages of the bills, the distribution of the bills, the collection of
amounts owed by OCCEL, and the preparation of the information for reconcilement
of accounts which it is the responsibility of TELEARMENIA to prepare.  These
billing costs will be readjusted annually in the percentage established by the
Telecommunications Regulatory Commission.  In the event that these costs are
not subject to regulation, TELEARMENIA may increase them up to a percentage
equal to that of the minimum wage increase, when it occurs.

FOURTH CLAUSE - LATE PAYMENT RECOVERY:  While the parties effect reconcilements
of accounts based upon a percentage of the total billable amount, as set forth
in point B.II.1 of the second clause of this contract, the recovery of the
amounts for calls made by TELEARMENIA subscribers and users to the OCCEL CTN
shall be the responsibility of TELEARMENIA.  Up to 8.5% of the total billable
amount for the portfolio of doubtful collection, calculated as indicated in
section B.II.1 of the second clause of this contract shall be borne by
TELEARMENIA.  As established in that section, the sums
<PAGE>   28
which exceed this 8.5% shall be paid to TELEARMENIA by OCCEL in the
reconcilement of accounts during which the respective calculation is made.  

In the event that the parties decide to effect reconcilements of accounts
based upon the sums collected by TELEARMENIA, the list of calls made by the
subscribers made by the TELEARMENIA subscribers to the OCCEL CTN shall be borne
by each company, according to the respective proportion.  The recovery of late
payments may be obtained by either OCCEL or TELEARMENIA, according to the
agreement made between the parties.  In any case, each party will submit to the
other the documents required for legal collection of these late payments.

FIFTH CLAUSE - ATTENTION TO CLAIMS:  The requests for explanations of the
billing of the calls made by TELEARMENIA subscribers and users to the OCCEL
cellular network shall be received and handled by OCCEL when such requests are
made at the offices of OCCEL, and shall be received and handled by TELEARMENIA
when such requests are made at the offices of TELEARMENIA.  The aforementioned
explanation shall consist of indication to the user of the manner in which the
calls made to the OCCEL cellular network are charged.  OCCEL shall supply
information in writing and shall instruct the TELEARMENIA employees as to the
rate schedule and the manner in which to handle these requests.

The claims pertaining to the billing of the calls made by the TELEARMENIA
subscribers and users to the OCCEL cellular network shall be received by OCCEL
or by TELEARMENIA, depending upon whether the user has contacted the offices of
OCCEL or TELEARMENIA.  The person receiving the claim shall immediately issue
to the claimant a provisional release in which exclusive deduction shall be made
of the total of the sums which are the subject of the claim concerning calls
made to the OCCEL cellular network.  At the points of payment of TELEARMENIA,
the user may pay his bill, accepting the amount of the discount specified in
the release.  In the event that the immediate issuance of provisional releases
causes a significant increase in unjustified claims, OCCEL may request the
suspension of this measure and the parties shall agree as to the adoption of an
alternative measure.  The format of the aforementioned provisional releases
shall be that agreed upon by the parties.  OCCEL shall supply this stationery to
TELEARMENIA.  OCCEL shall deliver to TELEARMENIA, at the office designated by
TELEARMENIA, a copy of the provisional releases which may have been issued by
OCCEL, accompanied by the copies of the page of the bill in which the breakdown
of the calls which are the subject of the claim is provided.  TELEARMENIA shall
deliver to OCCEL, at the office in the city of Armenia determined by OCCEL, the
copies of the provisional releases which may have been issued by TELEARMENIA,
accompanied by the copies of the page of the bill in which the breakdown of the
calls which are the subject of the claim is provided.

TELEARMENIA shall investigate and resolve the claims which are made by the
TELEARMENIA subscribers and users for calls made to the OCCEL CTN, when in
those claims the claimant

<PAGE>   29
argues that at the time of effecting the calls his/her telephone did not have
access to the cellular network or that it was out of service for some reason
which TELEARMENIA must verify.  The claims in which the claimant asserts reasons
other the two preceding reasons shall be investigated and resolved by OCCEL.  In
the case claims which merit this, OCCEL and TELEARMENIA shall conduct the
investigations which correspond to each party, providing each other with the
required operative and technical support and sharing all required information.

Within a period not to exceed fifteen (15) business days from the date on which
the claim report was issued, the party responsible for its investigation and
resolution shall make a decision with regard thereto and send a written
response to the claimant, with a copy to the other party.  In the
aforementioned response indication shall be given of the reasons for the
rejection if the claim has no basis, or the amount and the items which are the
object of the definitive discount if the claim has been accepted.  If no
response is sent to the user within the aforementioned term, it shall be
understood that the claim has been resolved in his/her favor.

If OCCEL so requests and there is the physical availability, TELEARMENIA shall
provide a space at its principal claims  handling facilities for OCCEL.  The
aforementioned space shall be destined for the receipt by OCCEL of claims which
are its responsibility to investigate and resolve.  The parties shall agree as
to the economic conditions under which TELEARMENIA will provide this space.

SIXTH CLAUSE - ANALYSIS AND RECOVERY OF FRAUDS AND INCONSISTENCIES : An
inconsistency is considered to be all inaccurate information about data
concerning the recording, payment or billing of a call, which temporarily or
permanently makes the billing process and the charging of this call to the user
who actually made it impossible.  There is temporary impossibility of billing
when the inaccuracy is solved after an analysis which makes it possible to
effect the billing in a subsequent period.  There is permanent impossibility
when, after the respective analysis, it is determined that respective charge
cannot be collected.  Each party shall be liable to the other for payment for
the inconsistencies which arise due to calls which originated on its network,
unless it is proven that such inconsistencies are imputable to inaccuracies or
errors committed by the other party.

It is considered that a fraud has been committed in a call when it has been
determined that collection definitively cannot be effected due to the
impossibility of billing to a subscriber or user, or due to the existence of a
claim for fraud resolved in favor of the claimant or not resolved, to the
detriment of the claimant, within the term established by the Law or by this
contract.

Fraudulent calls, among others, are considered to be those calls in which the
number from which they are made has not been assigned to any subscriber or
user, the calls which
<PAGE>   30
were never billed to the subscriber or which, having been billed, were deducted
subsequently from the account of the subscriber, those made from telephones
which were disconnected or out of service at the time the call was made, or
those in which the fraud occurred due to damage to the systems of assessment or
billing of either of the parties.  Each party shall be liable to the other for
the payment of the fraudulent calls which originate from its network.

In all cases where there is any suspicion of fraud, the executives in charge of
the management of this agreement shall determine the liability for the payment
of the fraudulent calls within sixty (60) days at maximum.  These executives
shall exempt TELEARMENIA from liability in the cases in which there is
consensus among them that TELEARMENIA took adequate measures on a timely basis
in order to prevent the fraud which took place, or in other special cases
which, due to their characteristics, justify the exemption of TELEARMENIA from
liability.  When within this term no liability has been established, and the
executives have not agreed as to mutual exemption from liability to be borne
by the parties, each party shall have the right to proceed with legal suits
in order for the liability for the fraud to be established by the authority
of jurisdiction. 

SEVENTH CLAUSE - BALANCE CONFRONTATION AND RECONCILING OF  ACCOUNTS:
TELEARMENIA and OCCEL shall maintain an accounting control which shall be
reconciled monthly in order to determine the net balance which the debtor party
must pay to the creditor party.  The dates for these reconcilings of accounts
shall be agreed upon by the executives responsible for the management of the
agreement.  For the effects of the reconciliation, parties may agree to offset
accounts for the leasing of systems and transmission media lease, leasing of
facilities for equipment location, leasing of electric and air conditioning
infrastructure, billing costs, payment for frauds and inconsistencies, interest
on late payment and any other concept related to the execution of this 
agreement.

In testimony whereof, this agreement is signed in the city of Armenia in two
copies with equal tenor.

administrative and customer service areas located at the TELEARMENIA
installations, the aforementioned fees shall be agreed upon by the parties in
each case, taking as a basis the lease prices for this type of installations
which are considered to be average for the real estate market of Armenia.

FOURTH CLAUSE - INCREASES AND DISCOUNTS:  All of the aforementioned rates may
be adjusted annually by TELEARMENIA in a maximum percentage to be established
by the Telecommunications Regulatory Commission or another body of
jurisdiction.  In the event that any of these rates is not subject to
regulations, TELEARMENIA may increase it in a percentage not to exceed the
percentage of the increase of the legal minimum wage, when this occurs.

In the event of an interruption caused by a failure in the transmission
infrastructure which TELEARMENIA has leased to OCCEL, TELEARMENIA shall deduct
a percentage from the
<PAGE>   32
respective monthly rents equal to the percentage of time, measured in relation
to the respective monthly period, during which the aforementioned
infrastructure suffered the damage which impeded its utilization for the
transmission of calls.  This discount shall not be applicable when the cause of
the interruption is imputable to OCCEL.

In testimony whereof, this agreement is signed in the city of Armenia in two
copies with equal tenor.

14, 1992, granted by the sole Notary of Soledad Atlantico, the party
hereinafter referred to as OCCEL S.A., an agreement is made to sign the present
Letter of Intent, subject to the following:

CONSIDERATIONS:

1. Law 37 of 1993 regulated the rendering of Mobile Cellular Telephone services
   and defined it as a non-residential public telecommunications service, of
   national scope and coverage.

2. OCCEL S.A. is the awardee of the concession which has as its object the
   rendering of a Cellular Mobile Telephone Service on the A network in the
   Western region of Colombia pursuant to concession agreement No. 000005 of
   1994 concluded between it and the Ministry of Communications on March 28,
   1994.

3. In accordance with the legal provisions which regulate this subject matter,
   Law 37 of 1993, Decree 741 of 1993, the mobile cellular telephone operators
   shall have the right to access to the fixed public switched telephone
   networks (PSTN) already established in the country, for the purposes of
   interconnection of the elements of their networks and to manage traffic.

4. In accordance with the provisions cited in the previous section the operators
   of the PSTN shall have the obligation to guarantee access of telephone
   traffic to the switching centers and to provide facilities for the location
   of the interconnection equipment within the equipment rooms of the
   aforementioned centrals, AC power supply, preventive and corrective
   maintenance and other facilities which are considered necessary either
   technically or administratively to the mobile operator, all at the expense of
   the cellular operator.

5. By means of Resolution 004 of 1993, it was established by the
   Telecommunications Regulatory Commission that the subscribers to the mobile
   telephone service shall pay for the calls which they make, and for those
   which utilize the long distance PSTN, the charge for the long distance
   service.

<PAGE>   2
6. It is necessary to proceed with the negotiation in order to establish
   the technical, legal, commercial, economic and financial conditions
   which shall constitute the Interconnection Agreement which shall be
   signed by the parties.

7. Until the action indicated in the preceding section is accomplished, it
   is indispensable to temporarily define the interconnection of the
   equipment of the networks of each of the parties and determine general
   parameters which permit the administration of the financial resources.

have such insertions as are appropriate or required or permitted by this
Agreement and may have such letters, numbers or other marks of identification
and such legends and endorsements typed, stamped, printed, lithographed or
engraved thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any

Company
<PAGE>   14
                                        9

shall approve the form of the Warrant Certificates and any notation, legend or
endorsement on them.

         The terms and provisions contained in the forms of the Warrant
Certificates annexed hereto as Exhibit A shall constitute, and are hereby
expressly made, a part of this Agreement.

         The definitive Warrant Certificates shall be typed, printed,
lithographed or engraved or produced by any combination of these methods, all as
determined by the officer of the Company executing such Warrant Certificates, as
evidenced by such officer's execution of such Warrant Certificates.

         Pending the preparation of definitive Warrant Certificates, temporary
Warrant Certificates may be issued, which may be printed, lithographed,
typewritten, mimeographed or otherwise produced, and which will be substantially
of the tenor of the definitive Warrant Certificates in lieu of which they are
issued.

         If temporary Warrant Certificates are issued, the Company will cause
definitive Warrant Certificates to be prepared without unreasonable delay. After
the preparation of definitive Warrant Certificates, the temporary Warrant
Certificates shall be exchangeable for definitive Warrant Certificates upon
surrender of the temporary Warrant Certificates to the Warrant Agent, without
charge to the Holder. Until so exchanged the temporary Warrant Certificates
shall in all respects be entitled to the same benefits under this Agreement as
definitive Warrant Certificates.

C on the face thereof.

         Section 2.3. Execution and Delivery of Warrant Certificates. Warrant
Certificates evidencing Warrants to purchase initially an aggregate of up to
4,355,852 Warrant Shares may be executed, on or after the Issue Date, by the
Company and delivered to the Warrant Agent for countersignature, and the Warrant
Agent shall thereupon countersign and deliver such Warrant Certificates upon the
order and at the direction of the Company to the purchasers thereof on the date
of issuance. The Warrant Agent is hereby authorized to countersign and deliver
Warrant Certificates as required by this Section 2.3 or by Section 2.4, 3.3, 5.3
or 5.4.

         The Warrant Certificates shall be executed on behalf of the Company by
its President or any Vice President, either manually or by facsimile signature
printed thereon. The Warrant Certificates shall be countersigned manually by the
Warrant Agent and shall not be valid for any purpose unless so countersigned. In
case any officer of the Company whose signature shall have been placed upon any
of the Warrant Certificates shall cease to be such officer of the Company before
countersignature by the Warrant Agent and issuance and delivery thereof, such
Warrant Certificates may, nevertheless, be countersigned by the Warrant Agent
and issued and delivered with the same force and effect as though such person
had not ceased to be such officer of the Company.

         Warrants offered and sold in reliance on Rule 144A shall be issued
initially in the form of a single, permanent global Warrant Certificate in
definitive, fully registered form, substantially in the form set forth in
Exhibit A (the "Rule 144A Global Warrant"), deposited with the Warrant Agent, as
custodian for DTC, duly executed by the Company and countersigned by the Warrant
Agent, and shall bear the legends set forth in Exhibits B, C, D and H. The
aggregate number of Warrants represented by the Rule 144A Global Warrant may
from time to time be increased or decreased by adjustments made on the records
of the Warrant Agent, as custodian for DTC, or its nominee, as hereinafter
provided.

         Warrants offered and sold in offshore transactions in reliance on
Regulation S shall be issued initially in the form of a single, permanent global
Warrant Certificate in definitive, fully registered form, substantially in the
form set forth in Exhibit A (the "Regulation S Global Warrant"), deposited with
the Warrant Agent, as custodian for DTC, duly executed by the Company and
countersigned by the Warrant Agent, and shall bear the legends set forth in
Exhibits C, D and H. The aggregate number of Warrants represented by the
Regulation S Global Warrant may from time to time be increased or decreased by
adjustments made on the records of the Warrant Agent, as custodian for DTC, or
its nominee, as hereinafter provided. The Rule 144A Global Warrant and the
Regulation S Global Warrant are sometimes collectively referred to herein as the
"Global Warrants".

         Warrants offered and sold in their initial distribution to a limited
number of institutions that are accredited investors (which are not QIBs) within
the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act (and
institutions in which all the equity
<PAGE>   16
                                       11

owners are such accredited investors) (together referred to as "Institutional
Accredited Investors") in transactions exempt from registration under the
Securities Act shall be issued as a Restricted Certificated Warrant,
substantially in the form set forth in Exhibit A, and shall bear the legends set
forth in Exhibit B, D and H. Such Warrants shall be delivered to such
Institutional Accredited Investors only upon the execution and delivery to the
Company and the Initial Purchasers of an institutional accredited investor
transferee compliance letter (an "Investor Letter") substantially in the form of
Exhibit E hereto. Restricted Certificated Warrants may not be transferred or
exchanged for interests in a Global Warrant or another Restricted Certificated
Warrant except as provided in Sections 5.3 and 5.4 hereof.

         Warrants issued pursuant to Section 5.3(b) in exchange for interests in
the Regulation S Global Warrant shall be issued in the form of permanent Warrant
Certificates in registered form in substantially the form set forth in Exhibit A
(the "Offshore Certificated Warrants") and shall bear the legend set forth in
Exhibit H. The Offshore Certificated Warrants and the Restricted Certificated
Warrants are sometimes collectively herein referred to as the "Certificated
Warrants".

         Section 2.4. Loss or Mutilation. Upon receipt by the Company and the
Warrant Agent of evidence satisfactory to them of the ownership and the loss,
theft, destruction or mutilation of any Warrant Certificate and of indemnity
satisfactory to them and (in the case of mutilation) upon surrender and
cancellation thereof, then, in the absence of notice to the Company or the
Warrant Agent that the Warrants represented thereby have been acquired by a bona
fide purchaser, the Company shall execute and the Warrant Agent shall
countersign and deliver to the registered Holder of the lost, stolen, destroyed
or mutilated Warrant Certificate, in exchange for or in lieu thereof, a new
Warrant Certificate of the same tenor and for a like aggregate number of
Warrants. Upon the issuance of any new Warrant Certificate under this Section 
2.4, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and other
expenses (including the reasonable fees and expenses of the Warrant Agent and of
counsel to the Company) in connection therewith. Every new Warrant Certificate
executed and delivered pursuant to this Section 2.4 in lieu of any lost, stolen
or destroyed Warrant Certificate shall constitute a contractual obligation of
the Company, whether or not the allegedly lost, stolen or destroyed Warrant
Certificates shall be at any time enforceable by anyone, and shall be entitled
to the benefits of this Agreement equally and proportionately with any and all
other Warrant Certificates duly executed and delivered hereunder. The provisions
of this Section 2.4 are exclusive and shall preclude (to the extent lawful) all
other rights or remedies with respect to the replacement of mutilated, lost,
stolen, or destroyed Warrant Certificates.

         Section 2.5. CUSIP Number. The Company in issuing the Warrants may use
a "CUSIP" number(s), and if so, the Warrant Agent shall use the CUSIP number(s)
in notices of repurchase as a convenience to Holders; provided that any such
notice may state
<PAGE>   17
                                       12

that no representation is made as to the correctness or accuracy of the CUSIP
number(s) printed in the notice or on the Warrants, and that reliance may be
placed only on the other identification numbers printed on the Warrants.

                                   ARTICLE III

               EXERCISE PRICE; EXERCISE AND REPURCHASE OF WARRANTS

         Section 3.1. Exercise Price. Each Warrant Certificate shall, when
countersigned by the Warrant Agent, entitle the Holder thereof, subject to and
upon compliance with the provisions of this Agreement, to purchase either (i)
0.22836 ADRs per Warrant, each ADR representing 25 fully paid and non-assessable
Warrant Shares, or (ii) if, at the time any Warrants are exercised, (x) the
Company has not entered into an ADR Deposit Agreement or (y) any Colombian
corporate or governmental authorizations set forth in Section 6.2(b) has not
been obtained or is not then in effect, 5.709 fully paid and non-assessable
Warrant Shares, at an exercise price of US$1.00 per Warrant Share (US$25.00 per
ADR) per Warrant, subject to adjustment as provided in Sections 4.1 and 4.2
hereof (the "Exercise Price"); provided, however, that if, on the date of
exercise of any Warrant, the Peso Equivalent of the Exercise Price is less than
the aggregate of the par value of the Warrant Shares represented by the ADRs or
the Warrant Shares, as the case may be, for which such Warrant may be exercised,
the Exercise Price payable upon such exercise shall be adjusted to be equal to
the Peso Equivalent of the aggregate of such par value.

         Section 3.2. Exercise; Restrictions on Exercise. Subject to the terms
and conditions set forth herein, the Warrants shall be exercisable at any time
or from time to time on any Business Day on or after the earliest to occur of
(i) June 7, 1998, (ii) the occurrence of a Change of Control, or (iii) the
consummation of a Public Equity Offering (the "Exercise Commencement Date") and
on or before the Expiration Date; provided, however, that Warrants may not be
exercised (i) prior to the date on which the Warrant Agent has received written
notice from the Company that a Registration Statement has been declared
effective with respect to the Warrant Shares, (ii) at any time after the Warrant
Agent has received written notice from the Company or the Commission that a stop
order issued by the Commission suspending the effectiveness of such Registration
Statement is in effect, (iii) prior to the date on which the Warrant Agent has
received written notice from the Company that the Company has obtained all
necessary Colombian corporate and governmental authorizations and approvals set
forth in Section 6.1 and 6.2(a), (iv) at any time after the Warrant Agent has
received written notice from the Company that the authorizations and approvals
referred to in clause (iii) are not in effect or (v) during any Suspension
Period permitted under Section 6.4(b)(ii), provided that the Warrant Agent has
received notice from the Company of such Suspension Period. If, at the time such
Warrants are exercised, (w) the Company has entered into an ADR Deposit
Agreement, (x) all
<PAGE>   18
                                       13

Colombian corporate and governmental authorizations set forth in Section 6.2(b)
have been obtained, (y) the Warrant Agent has been notified that both (w) and
(x) of this Section 3.2 have occurred, and (z) the Warrant Agent has not
received written notice from the Company that any of the authorizations and
approvals set forth in Section 6.2(b) is not in effect, such Warrants shall be
exercisable only to purchase ADRs. Any Warrants not exercised by 5:00 p.m., New
York City time, on the Expiration Date shall expire and all rights of the
Holders of such Warrants shall terminate, except the right to receive cash in a
Warrant Repurchase as provided in Section 3.4. The Company shall give notice not
less than 90, and not more than 120, calendar days prior to the Expiration Date
to the Holders of all then outstanding Warrants to the effect that the Warrants
will terminate and become void as of the close of business on the Expiration
Date.

         Additionally, pursuant to Section 4.1(h)(ii) hereof, the Warrants may
expire and all rights of the Holders of such Warrants shall terminate in the
event the Company merges or consolidates with or sells all or substantially all
of its property and assets to a Person (other than an Affiliate of the Company)
if the consideration payable to holders of shares of Class B Common Stock in
exchange for their Class B Common Stock in connection with such merger,
consolidation or sale consists solely of cash. The Company shall give the
Warrant Agent written notice of either of the events described in this paragraph
immediately upon the occurrence thereof.

         Section 3.3. Method of Exercise; Payment of Exercise Price. (a) (i) In
order to exercise all or any of the Warrants represented by a Warrant
Certificate, the Holder thereof shall surrender for exercise the Warrant
Certificate to the Warrant Agent at its corporate trust office set forth in
Section 10.5 hereof, with the Subscription Form set forth in the Warrant
Certificate (or a copy thereof furnished by the Warrant Agent) duly executed,
together with payment in full of the Exercise Price then in effect for each ADR,
Warrant Share or other securities or property issuable upon exercise of the
exercised Warrants; such payment shall be made in cash or by certified or
official bank or bank cashier's check payable to the order of the Company.

         (ii) Upon receipt of the Warrant Certificate, the duly executed
Subscription Form and such payment, the Warrant Agent shall promptly notify the
Company in writing of such surrender. If the Exercise Price has been adjusted
pursuant to the provision of Section 3.1 and notice of such adjustment has not
previously been given in accordance with Section 4.3, the Company will promptly
notify the exercising Holder and the Warrant Agent in writing of the adjusted
Exercise Price (a "Par Value Notice").

         (iii) If the Company is obligated to deliver a Par Value Notice
pursuant to Section 3.3(a)(ii), the surrendering Holder may elect:
<PAGE>   19
                                       14

                  (A) to exercise such Warrants at the adjusted Exercise Price
         by notifying the Warrant Agent of such election and paying to the
         Warrant Agent an amount equal to the difference between the adjusted
         Exercise Price for such Warrants and the amount previously paid by such
         Holder pursuant to clause (i) of this Section 3.3(a); such payment
         shall be made in cash or by certified or official bank or bank
         cashier's check payable to the order of the Company; or

                  (B) to withdraw such surrendered Warrants and receive a refund
         of the Exercise Price paid pursuant to clause (i) of this Section 
         3.3(a); in such case the Warrant Agent shall refund such payment as
         promptly as is practicable in cash or by certified or official bank or
         bank cashier's check payable to such Person or Persons as it may be
         directed in writing by the surrendering Holder, net of any transfer
         taxes required to be paid in the event that the check is to be
         delivered to a Person other than the Holder.

                  (iv) Except as provided in clause (iii) of this Section 
3.3(a), all payments received upon exercise of Warrants shall be delivered to
the Company by the Warrant Agent as reasonably instructed in writing by the
Company. If fewer than all the Warrants represented by a Certificated Warrant
are exercised, such Certificated Warrant shall be surrendered and a new
Certificated Warrant of the same tenor and for the number of Warrants which were
not exercised shall be executed by the Company and delivered to the Warrant
Agent and the Warrant Agent shall countersign the new Certificated Warrant,
registered in such name or names as may be directed in writing by the Holder,
and shall deliver the new Certificated Warrant to the Person or Persons entitled
to receive the same. If fewer than all of the Warrants represented by a Global
Warrant are exercised, the Global Warrant shall not be surrendered to the
Warrant Agent in accordance with Section 3.3(a)(i) and the Warrant Agent shall
decrease or reflect on its records, as custodian for DTC, or its nominee, a
decrease in the aggregate number of Warrants represented by such Global Warrant
equal to the number of Warrants exercised.

                  (v) Upon exercise of any Warrants in accordance with the
foregoing provisions, (i) (x) the Company shall issue such number of Warrant
Shares as are issuable upon the exercise of such Warrants to the ADR Depositary
and shall issue the other securities or property (including money), if any, to
which such exercising Holder is then entitled and (y) the ADR Depositary,
pursuant to the ADR Deposit Agreement, upon instructions from the Warrant Agent,
shall issue ADRs to which such exercising Holder is then entitled, or (ii) if
the Company has not entered into an ADR Deposit Agreement or any Colombian
corporate or governmental authorizations set forth in Section 6.2(b) have not
been obtained or are not then in effect, the Company shall issue such number of
Warrant Shares and the other securities or property (including money), if any,
to which such exercising Holder is then entitled, in either case, subject to the
conditions set forth below.
<PAGE>   20
                                       15

                  (b) If (w) the Company has entered into an ADR Deposit
Agreement, (x) all Colombian corporate and governmental authorizations set forth
in Section 6.2(b) have been obtained, (y) the Warrant Agent has received written
notice from the Company that both (w) and (x) of this paragraph (b) have
occurred, and (z) the Warrant Agent has not received written notice from the
Company that any of the authorizations and approvals set forth in Section 6.2(b)
is not in effect, upon exercise of any Warrants in accordance with the foregoing
provisions:

                  (i) the Warrant Agent shall notify the ADR Depositary in
         writing that such Holder has elected to exercise such Warrants;

                  (ii) the Company shall promptly issue to the ADR Custodian
         appropriate evidence of ownership of the Warrant Shares to be
         represented by the ADRs to which such Holder is entitled, registered or
         otherwise placed in such name or names as may be directed in writing by
         the ADR Custodian, and to deliver such evidence of ownership to the ADR
         Custodian;

                  (iii) the Warrant Agent shall instruct the ADR Depositary to
         issue, upon receipt of appropriate evidence of ownership of the Warrant
         Shares by the ADR Custodian, ADRs representing such Warrant Shares to
         the Holder or upon the written order of the Holder of such Warrant
         Certificate and to transfer and deliver promptly to the Holder or upon
         the written order of the Holder of such Warrant Certificate appropriate
         evidence of ownership of ADRs representing such Warrant Shares,
         registered or otherwise placed in such name or names as may be directed
         in writing by the Holder; and

                  (iv) the Warrant Agent shall instruct the Company to transfer
         promptly to the Holder or upon the written order of the Holder of such
         Warrant Certificate appropriate evidence of ownership of any other
         securities or property (including money) to which it is entitled,
         registered or otherwise placed in such name or names as may be directed
         in writing by the Holder, and to deliver such evidence of ownership and
         the other securities or property (including money), if any, to the
         Person or Persons entitled to receive the same, together with an amount
         in cash in lieu of any fraction of an ADR as provided in Section 4.6
         hereof;

provided that the Holder of such Warrant shall be responsible for the payment of
any transfer taxes required as the result of any change in ownership of such
Warrants or the issuance of such ADRs or other securities or property (including
money) other than to the registered owner of such Warrants and the Company may
deduct such taxes from any payment of money to be made and shall not be required
to issue or deliver such Warrant Shares (if such taxes are not deducted in full)
unless and until the Holder shall have paid to the Company the
<PAGE>   21
                                       16

amount of such tax or shall have established to the satisfaction of the Company
and the Warrant Agent that such tax has been paid.

                  (c) If (x) the Warrant Agent has not been notified in writing
by the Company that the Company has entered into an ADR Deposit Agreement and
that all Colombian corporate or governmental authorizations set forth in 
Section 6.2(b) have been obtained or (y) the Warrant Agent has received 
written notice from the Company that any of the authorizations and approvals 
referred set forth in Section 6.2(b) is not in effect, upon exercise of any 
Warrants, following surrender of a Warrant Certificate in conformity with the 
foregoing provisions, the Warrant Agent shall instruct the Company to transfer 
promptly to or upon the written order of the Holder of such Warrant 
Certificate appropriate evidence of ownership of any Warrant Shares or the 
other securities or property (including money), if any, to which such 
exercising Holder is then entitled, registered or otherwise placed in such 
name or names as may be directed in writing by the Holder, and to deliver such 
evidence of ownership and the other securities or property (including money), 
if any, to the Person or Persons entitled to receive the same, together with 
an amount in cash in lieu of any fraction of a share as provided in Section 
4.6 hereof; provided that the Holder of such Warrant shall be responsible for 
the payment of any transfer taxes required as the result of any change in 
ownership of such Warrants or the issuance of Warrant Shares other than to the 
registered owner of such Warrants and the Company may deduct such taxes from 
any payment of money to be made and shall not be required to issue or deliver 
such Warrant Shares (if such taxes are not deducted in full) unless and until 
the Holder shall have paid to the Company the amount of such tax or shall have 
established to the satisfaction of the Company and the Warrant Agent that such 
tax has been paid.

                  (d) Upon exercise of a Warrant or Warrants, the Warrant Agent
is hereby authorized and directed to instruct the ADR Depositary or any transfer
agent of the Warrant Shares, as the case may be, (and the ADR Depositary and all
such transfer agents are hereby irrevocably authorized to comply with all such
instructions) in accordance with paragraph (b) or (c), as the case may be, of
this Section 3.3, to issue, transfer and deliver certificates for the necessary
number of ADRs or Warrant Shares, as the case may be, to which the Holder of the
Warrant or Warrants may be entitled. A Warrant shall be deemed to have been
exercised immediately prior to the close of business on the date of exercise, as
provided in and in accordance with paragraph (a) of this Section 3.3, of such
Warrant and, for all purposes of this Agreement, the Person entitled to receive
any ADRs, Warrant Shares or other securities or property deliverable upon such
exercise shall, as between such Person and the Company, be deemed to be the
Holder of such ADRs, Warrant Shares or other securities or property of record as
of the close of business on such date and shall be entitled to receive, and the
Company shall deliver to such Person, the Warrant Shares and the other
securities or property (including money), if any, and the ADR Depositary shall
deliver to such Person any ADRs, to which he would have been entitled had he
been the record holder on such date. Without limiting the foregoing, if, at the
date referred to above, the transfer books for the
<PAGE>   22
                                       17

ADRs, Warrant Shares or other securities purchasable upon the exercise of the
Warrants shall be closed, the certificates for the ADRs, Warrant Shares or other
securities in respect of which such Warrants are then exercised shall be
issuable as of the date on which such books shall next be opened, and until such
date the Company shall be under no duty to deliver any certificate for such
Warrant Shares or other securities and the ADR Depositary shall be under no duty
to deliver any certificate for such ADRs; provided that the transfer books or
records, unless required by law, shall not be closed at any one time for a
period longer than 20 calendar days.

                  Section 3.4. Repurchase of Warrants. (a) Repurchase of
Warrants. If a Trading Market does not exist for the Warrant Shares or the ADRs
on the Expiration Date or, if for any reason such day is not a trading day or
trading in securities of such type on such day is limited or suspended, the next
preceding day which is a trading day and on which trading in securities of such
type is not limited or suspended (the "Preceding Trading Day"), the Company
shall repurchase all outstanding Warrants that have not been exercised on or
prior to the Expiration Date for cash at the Warrant Repurchase Price (the
"Warrant Repurchase"), pursuant to the provisions of this Section 3.4. The
purchase price (the "Warrant Repurchase Price") for each Warrant shall be equal
to the Current Market Value on the Expiration Date (or the Preceding Trading
Day, if applicable) of the ADRs or Warrant Shares issuable, and the other
securities or property (including money), if any, of the Company which would
have been delivered, upon exercise of Warrants had the Warrants been exercised
(regardless of whether the Warrants are then exercisable), less the Exercise
Price for such Warrant in effect on the Expiration Date. On the Expiration Date,
the Company shall give written notice to the Holders of all then outstanding
Warrants to the effect that the Warrants have terminated and become void, except
for the right of the Holders thereof to receive cash payment therefor as
provided below and, if a Trading Market does not exist for the Warrant Shares or
the ADRs as provided herein, shall give written notice thereof to the Warrant
Agent.

                  (b) Selection of Independent Financial Advisor. In the event
of a Warrant Repurchase, the Current Market Value shall be deemed to be equal to
the value set forth in a Value Report as determined by an Independent Financial
Expert (which may be the same Independent Financial Expert as the Independent
Financial Expert selected pursuant to Section 3.5(b)), which shall be selected
by the Board of Directors not more than ten Business Days following the
Expiration Date, and retained on customary terms and conditions, using one or
more valuation methods that the Independent Financial Expert, in its best
professional judgment, determines to be most appropriate, but without giving
effect to any discount for lack of liquidity, the fact that the Company has no
class of equity securities registered under the Exchange Act or the fact that
ADRs, Warrant Shares and other securities or property issuable upon exercise of
the Warrants represent a minority interest in the Company but giving effect to
the issuance of ADRs, Warrant Shares and other securities issuable upon exercise
of all outstanding Warrants. Within two calendar days after such selection of
the
<PAGE>   23
                                       18

Independent Financial Expert, the Company shall deliver to the Warrant Agent a
notice setting forth the name of such Independent Financial Expert. The Company
shall cause the Independent Financial Expert to deliver a Value Report to the
Company, and the Company shall deliver to the Warrant Agent, within 45 calendar
days of the appointment of the Independent Financial Expert, a Value Certificate
attaching the Value Report. The Warrant Agent shall have no duty with respect to
the Value Report of any Independent Financial Expert, except to keep it on file
and available for inspection by the Holders. The determination as to Current
Market Value in accordance with the provisions of this Section 3.4(b) shall be
conclusive on all Persons.

                  (c) Notice of Warrant Repurchase. As promptly as practicable
following the delivery of the Value Report by the Independent Financial Expert
to the Company, the Company shall give notice of the terms of the Warrant
Repurchase (a "Repurchase Notice") to each Holder, as of the Expiration Date, of
then outstanding Warrants. Each Repurchase Notice: (i) shall be given by the
Company directly to all Holders of the Warrants, with a copy to the Warrant
Agent and (ii) shall be given within five Business Days after the Company
receives the Value Report and shall specify (A) the manner in which Warrants may
be surrendered to the Warrant Agent for repurchase by the Company, (B) the
Warrant Repurchase Price at which the Warrants will be repurchased by the
Company, (C) the name of the Independent Financial Expert whose valuation of the
ADRs, Class B Common Stock and other securities or property was utilized in
connection with determining such Repurchase Price and (D) that payment of the
Warrant Repurchase Price will be made by the Warrant Agent. Each such notice
shall be accompanied by a Certificate for Surrender for Repurchase in
substantially the form attached to the Warrant Certificate and a copy of the
Value Report.

                  (d) Payment for Warrants. (i) To receive payment for any
unexercised Warrants pursuant to this Section 3.4, each Holder thereof shall,
except as otherwise provided herein, surrender to the Warrant Agent the Warrant
Certificates evidencing such Holder's Warrants, together with a duly executed
Certificate for Surrender for Repurchase in substantially the form attached to
the Warrant Certificate.

                  (ii) As promptly as practicable following the Expiration Date,
the Company shall deposit with the Warrant Agent funds sufficient to make
payment for all unexercised Warrants. After receipt of such deposit from the
Company, the Warrant Agent shall make payment to each Holder, by delivering a
check in an amount equal to the Warrant Repurchase Price for each Warrant
surrendered by such Holder in accordance with this Section 3.4, to such Person
or Persons as it may be directed in writing by any Holder surrendering Warrant
Certificates representing such Warrants, net of any transfer taxes required to
be paid in the event that the check is to be delivered to a Person other than
the Holder and net of any amounts to be withheld pursuant to Section 7.2.
<PAGE>   24
                                       19

                  (e) Compliance with Laws. Notwithstanding anything contained
in this Section 3.4, if the Company is required to comply with laws or
regulations in connection with making the Warrant Repurchase, such laws or
regulations shall govern the making of such Warrant Repurchase. The Company
shall immediately notify the Warrant Agent in writing if any such laws or
regulations shall require the Company to supplement or amend this Agreement or
to modify or amend the procedures or manner of such repurchase or any other
provisions set forth herein and the Warrant Agent shall not be responsible or
liable for making any such determination, complying with any such laws or
regulations or for the failure of the Company to so notify the Warrant Agent.

                  Section 3.5. Repurchase Offers. (a) Notice of Repurchase
Event. If a Trading Market does not exist for the Warrant Shares or the ADRs on
the Expiration Date or, in the circumstances described in Section 3.4(a), the
Preceding Trading Day, the Company shall offer to repurchase all ADRs and
Warrant Shares (other than Warrant Shares held by the ADR Depositary)
outstanding on the Expiration Date and, to the extent that there is no Trading
Market therefor, all securities issued upon exercise of the Warrants or
distributed in respect of the Warrants or Warrant Shares and then held by the
holder of such ADRs and Warrant Shares and that, in each case, are properly
tendered to the Warrant Agent on or prior to the expiration date (as hereinafter
defined in this Section 3.5(a)) for such offer for cash at the Repurchase Price
(the "Repurchase Offer"), pursuant to the provisions of this Section 3.5. The
purchase price (the "Repurchase Price") for each ADR or Warrant Share properly
tendered to the Warrant Agent pursuant to a Repurchase Offer shall be equal to
the Current Market Value of such ADR or Warrant Share and such other securities
as of the Expiration Date or the Preceding Trading Day, if applicable (after
giving effect to the issuance of ADRs, Warrant Shares and other securities
issuable upon exercise of all outstanding Warrants). The Repurchase Offer shall
commence on the date on which the Company gives an Offer Notice for such
Repurchase Offer and shall expire at 5:00 p.m., New York City time, on a date
determined by the Company (the "expiration date") that is at least 30 but not
more than 60 calendar days after the Notice Date.

                  (b) Selection of Independent Financial Advisor. In the event
of a Repurchase Offer, the Current Market Value of the ADRs and Warrant Shares
and such other securities or property referred to in the preceding paragraph
shall be deemed to be equal to the value set forth in a Value Report as
determined by an Independent Financial Expert (which may be the same Independent
Financial Expert as the Independent Financial Expert selected pursuant to
Section 3.4(b)), which shall be selected by the Board of Directors not more than
ten Business Days following the Expiration Date, and retained on customary terms
and conditions, using one or more valuation methods that the Independent
Financial Expert, in its best professional judgment, determines to be most
appropriate, but without giving effect to any discount for lack of liquidity,
the fact that the Company has no class of equity securities registered under the
Exchange Act or the fact that the ADRs, Warrant Shares and other securities or
property issuable upon exercise of the Warrants represent a
<PAGE>   25
                                       20

minority interest in the Company but giving effect to the issuance of ADRs,
Warrant Shares and other securities issuable upon exercise of all outstanding
Warrants. Within two calendar days after such selection of the Independent
Financial Expert, the Company shall deliver to the Warrant Agent a notice
setting forth the name of such Independent Financial Expert. The Company shall
cause the Independent Financial Expert to deliver a Value Report to the Company,
and the Company shall deliver to the Warrant Agent, within 45 calendar days of
the appointment of the Independent Financial Expert, a Value Certificate
attaching the Value Report. The Warrant Agent shall have no duty with respect to
the Value Report of any Independent Financial Expert, except to keep it on file
and available for inspection by the holders of the ADRs or Warrant Shares. The
determination as to Current Market Value in accordance with the provisions of
this Section 3.5 shall be conclusive on all Persons.

                  (c) Notice of Repurchase Offer. As promptly as practicable
following the delivery of the Value Report by the Independent Financial Expert
to the Company, the Company shall give notice of the Repurchase Offer (an "Offer
Notice") to each Holder, as of the Expiration Date, of then outstanding ADRs and
Warrant Shares. Such Offer Notice: (i) shall be given by the Company directly to
all holders of ADRs and Warrant Shares, with a copy to the Warrant Agent and
(ii) shall be given within five Business Days after the Company receives the
Value Report with respect to such offer and shall specify (A) the expiration
date for such Repurchase Offer, (B) the manner in which ADRs or Warrant Shares
and such other securities or property referred to above may be surrendered to
the Warrant Agent for repurchase by the Company, (C) the Repurchase Price at
which the ADRs or Warrant Shares and such other securities or property referred
to above will be repurchased by the Company, (D) the name of the Independent
Financial Expert whose valuation of the ADRs, shares of Class B Common Stock and
other securities or property was utilized in connection with determining such
Repurchase Price and (E) that payment of the Repurchase Price will be made by
the Warrant Agent. Each such notice shall be accompanied by a Certificate for
Surrender for Repurchase of ADRs or Warrant Shares in substantially the form
attached to the Warrant Certificate and a copy of the Value Report.

                  (d) Payment for ADRs and Warrant Shares. (i) Each Holder of
ADRs or Warrant Shares may, but shall not be obligated to, accept such
Repurchase Offer by tendering to the Warrant Agent, on or prior to the
expiration date for such Repurchase Offer, the ADR certificate or Warrant Share
certificate evidencing the ADRs or Warrant Shares, as the case may be, together
with such other securities referred to above that are subject to such Repurchase
Offer, together with a completed Certificate for Surrender for Repurchase of
ADRs or Warrant Shares (and such other securities) in substantially the form
attached to the Warrant Certificate. A Holder of ADRs or Warrant Shares (and
such other securities) may withdraw all or a portion of the ADRs or Warrant
Shares (together with all or a proportionate amount of such other securities)
tendered to the Warrant Agent at any time prior to the expiration date for such
Repurchase Offer. If less than all the ADRs or Warrant Shares (and such other
securities) represented by an ADR certificate or Warrant Share

certificate, as the case may be, shall be tendered, such ADR certificate or
Warrant Share certificate shall be surrendered and a new ADR certificate or
Warrant Share certificate of the same tenor and for the number of ADRs or
Warrant Shares (and such other securities) which were not tendered shall be
executed by the Company and, if applicable, the ADR Depositary, and delivered to
the Warrant Agent, registered in such name or names as may be directed in
writing by the Holder of such ADRs or Warrant Shares, and the Warrant Agent
shall deliver the new ADR certificate or Warrant Share certificate to the Person
or Persons entitled to receive the same; provided that the Holder of such ADRs
or Warrant Shares shall be responsible for the payment of any transfer taxes
required as the result of any change in ownership of such ADRs or Warrant
Shares.

                  (ii) Upon surrender for repurchase of any ADRs or Warrant
Shares and such other securities referred to above in conformity with the
provisions of this Section 3.5, the Warrant Agent shall thereupon promptly
notify the Company of such surrender. On or before the expiration date for such
Repurchase Offer, the Company shall deposit with the Warrant Agent funds
sufficient to make payment for the ADRs and Warrant Shares and such other
securities or property referred to above tendered to the Warrant Agent and not
withdrawn. Following the expiration date for such Repurchase Offer and the
receipt of such deposit from the Company, the Warrant Agent shall make payment,
by delivering a check in an amount equal to the Repurchase Price of each ADR
certificate or Warrant Share and such other securities or property referred to
above surrendered by such Holder, to such Person or Persons as it may be
directed in writing by the Holder surrendering such ADRs or Warrant Shares and
such other securities or property referred to above net of any transfer taxes
required to be paid in the event that the check is to be delivered to a Person
other than such Holder and net of any amounts to be withheld pursuant to 
Section 7.2.

                  (e) Compliance with Laws. Notwithstanding anything contained
in this Section 3.5, if the Company is required to comply with laws or
regulations in connection with making the Repurchase Offer, such laws or
regulations shall govern the making of such Repurchase Offer. The Company shall
immediately notify the Warrant Agent in writing if any such laws or regulations
shall require the Company to supplement or amend this Agreement or to modify or
amend the procedures or manner of such repurchase or any other provisions set
forth herein and the Warrant Agent shall not be responsible or liable for making
any such determination or for the failure of the Company to so notify the
Warrant Agent.

                  Section 3.6. Inability to Consummate Warrant Repurchase or
Repurchase Offer. (a) In the event that the Company's consummation of a Warrant
Repurchase or a Repurchase Offer or the payment of cash in lieu of fractional
ADRs or Warrant Shares pursuant to Section 4.6 would violate the provisions of
any applicable law, rule or regulation or result in a default under any of its
indentures, mortgages, loan agreements or other agreements or instruments, the
Company need not consummate such Warrant Repurchase,
<PAGE>   27
                                       22

pay such cash in lieu of fractional ADRs or Warrant Shares or make such
Repurchase Offer or, if such Repurchase Offer has commenced, the Company may
terminate such Repurchase Offer prior to its purchase of any ADRs or Warrant
Shares thereunder; provided, however, that, if after taking into account the
foregoing provisions, the Company would be permitted to consummate a Warrant
Repurchase or make a Repurchase Offer in part but not in full, the Company shall
only be obligated to consummate such Warrant Repurchase or make such Repurchase
Offer to the maximum extent permissible. In such event, the Company shall
promptly notify the Warrant Agent and the Holders in writing of its inability to
effect such Warrant Repurchase, Repurchase Offer or payment of cash in lieu of
fractional ADRs or Warrant Shares and whether the Company is permitted to
consummate the Warrant Repurchase or the Repurchase Offer in part.

                  (b) In the event that a Warrant Repurchase is not consummated,
a Repurchase Offer is not commenced or is terminated or a payment in lieu of
fractional ADRs or Warrant Shares is not made, in each case, pursuant to 
Section 3.6(a), the Company shall remain obligated to consummate such Warrant
Repurchase, to make such Repurchase Offer and to make such payment in lieu of
fractional ADRs or Warrant Shares at such time as such Warrant Repurchase,
Repurchase Offer or payment in lieu of fractional ADRs or Warrant Shares would
not violate the provisions of any applicable law, rule or regulation or result
in a default under any of its indentures, mortgages, loan agreements or other
agreements or instruments and shall be obligated to pay interest on the amounts
that would otherwise be due to the Holders as provided by Section 7.3. Upon the
date on which all limitations upon the Company's ability to repurchase Warrants,
ADRs or Warrant Shares or make payments in lieu of fractional ADRs or Warrant
Shares, as the case may be, are removed, the Company's repurchase obligations
pursuant to Sections 3.4 and 3.5 and the Company's obligation to make payments
in lieu of fractional ADRs or Warrant Shares pursuant to Section 4.6 shall be
reinstated effective as of the date of the such removal, and the time periods
under Sections 3.4 and 3.5 shall be calculated as if such date were the
Expiration Date, except for purposes of calculating interest pursuant to 
Section 7.3.

                                   ARTICLE IV

                                   ADJUSTMENTS

                  Section 4.1. Adjustments. The Exercise Price and the number of
ADRs or Warrant Shares issuable upon exercise of each Warrant shall be subject
to adjustment from time to time as follows:

                  (a) Stock Dividends; Stock Splits; Reverse Stock Splits;
Reclassifications. In case the Company shall (i) pay a dividend or make any
other distribution with respect to its Common Stock in shares of any class or
series of its capital stock, (ii) subdivide its
<PAGE>   28
                                       23

outstanding Common Stock, (iii) combine its outstanding Common Stock into a
smaller number of shares or (iv) issue any shares of its capital stock in a
reclassification of its Common Stock (other than a reclassification in
connection with a merger, consolidation or other business combination which will
be governed by Section 4.1(h)), the number of ADRs or Warrant Shares purchasable
upon exercise of each Warrant immediately prior to the record date for such
dividend or distribution or the effective date of such subdivision, or
combination or reclassification shall be adjusted so that the Holder of each
Warrant shall thereafter be entitled to receive the kind and number of ADRs or
shares of Common Stock or other securities of the Company which such Holder
would have been entitled to receive after the happening of any of the events
described above had such Warrant been exercised immediately prior to the
happening of such event or any record date with respect thereto. An adjustment
made pursuant to this Section 4.1(a) shall become effective immediately after
the effective date of such event retroactive to the record date, if any, for
such event.

                  (b) Rights; Options; Warrants. In case the Company shall issue
rights, options, warrants or convertible or exchangeable securities (other than
a convertible or exchangeable security subject to Section 4.1(a)) to all holders
of its Common Stock, entitling them to subscribe for or purchase shares of
Common Stock at a price per share which is lower (at the record date for such
issuance) than the then Current Market Value per share of Common Stock, the
number of ADRs or Warrant Shares thereafter purchasable upon the exercise of
each Warrant shall be determined by multiplying the number of ADRs or Warrant
Shares theretofore purchasable upon exercise of each Warrant by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to the issuance of such rights, options, warrants or
convertible or exchangeable securities plus the number of additional shares of
Common Stock offered for subscription or purchase, and the denominator of which
shall be the number of shares of Common Stock outstanding immediately prior to
the issuance of such rights, options, warrants or convertible or exchangeable
securities plus the number of shares which the aggregate offering price of the
total number of shares of Common Stock so offered would purchase at the then
Current Market Value per share of Common Stock. Such adjustment shall be made
whenever such rights, options, warrants or convertible or exchangeable
securities are issued, and shall become effective retroactively immediately
after the record date for the determination of shareholders entitled to receive
such rights, options, warrants or convertible or exchangeable securities.

                  (c) Issuance of Common Stock at Lower Values. In case the
Company shall, in a transaction in which Sections 4.1(a) and 4.1(b) are
inapplicable, issue or sell shares of Common Stock, or rights, options, warrants
or convertible or exchangeable securities containing the right to subscribe for
or purchase shares of Common Stock, at a price per share of Common Stock
(determined in the case of such rights, options, warrants or convertible or
exchangeable securities, by dividing (A) the total amount receivable by the
Company in consideration of the issuance and sale of such rights, options,
warrants or
<PAGE>   29
                                       24

convertible or exchangeable securities, plus the total consideration, if any,
payable to the Company upon exercise, conversion or exchange thereof, by (B) the
total number of shares of Common Stock covered by such rights, options, warrants
or convertible or exchangeable securities) that is lower than the Current Market
Value per share of Common Stock in effect immediately prior to such sale or
issuance, then the number of ADRs or Warrant Shares thereafter purchasable upon
the exercise of each Warrant shall be determined by multiplying the number of
ADRs or Warrant Shares theretofore purchasable upon exercise of such Warrant by
a fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately after such sale or issuance and the denominator of which
shall be the number of shares of Common Stock outstanding immediately prior to
such sale or issuance plus the number of shares of Common Stock which the
aggregate consideration received (determined as provided below) for such sale or
issuance would purchase at such Current Market Value per share of Common Stock.
Such adjustment shall be made successively whenever any such sale or issuance is
made. For purposes of this Section 4.1(c), the shares of Common Stock which the
holder of any such rights, options, warrants or convertible or exchangeable
securities shall be entitled to subscribe for or purchase shall be deemed to be
issued and outstanding as of the date of such sale and issuance and the
consideration received by the Company therefor shall be deemed to be the
consideration received by the Company for such rights, options, warrants or
convertible or exchangeable securities, plus the consideration or premiums
stated in such rights, options, warrants or convertible or exchangeable
securities to be paid for the shares of Common Stock covered thereby.

                  In case the Company shall issue and sell shares of Common
Stock or rights, options, warrants or convertible or exchangeable securities
containing the right to subscribe for or purchase shares of Common Stock for a
consideration consisting, in whole or in part, of property other than cash or
its equivalent, then in determining the "price per share of Common Stock" and
the "consideration" receivable by or payable to the Company for purposes of the
first sentence of this Section 4.1(c), the Board of Directors of the Company
shall determine, in good faith, the fair value of such property, which
determination shall be evidenced by a resolution of the Board of Directors of
the Company. In case the Company shall issue and sell rights, options, warrants
or convertible or exchangeable securities containing the right to subscribe for
or purchase shares of Common Stock, together with one or more other securities
as part of a unit at a price per unit, then in determining the "price per share
of Common Stock" and the "consideration" receivable by or payable to the Company
for purposes of the first sentence of this Section 4.1(c), the Board of
Directors of the Company shall determine, in good faith, the fair value of the
rights, options, warrants or convertible or exchangeable securities then being
sold as part of such unit, which determination shall be evidenced by a
resolution of the Board of Directors of the Company.

                  (d) Distributions of Debt, Assets, Subscription Rights or
Convertible Securities. In case the Company shall fix a record date for the
making of a distribution to all
<PAGE>   30
                                       25

holders of its Common Stock of evidences of its indebtedness, assets, Excess
Cash Dividends (excluding dividends or distributions referred to in Section 
4.1(a) above and excluding cash dividends other than Excess Cash Dividends) or
securities (excluding those referred to in subsections 4.1(a), 4.1(b) and 4.1(c)
above), then in each case the number of ADRs or Warrant Shares purchasable after
such record date upon the exercise of each Warrant shall be determined by
multiplying the number of ADRs or Warrant Shares purchasable upon the exercise
of such Warrant immediately prior to such record date by a fraction, the
numerator of which shall be the Current Market Value per share of Common Stock
immediately prior to the record date for such distribution and the denominator
of which shall be the Current Market Value per share of Common Stock immediately
prior to the record date for such distribution less the then fair value (as
determined in good faith by the Board of Directors of the Company, which
determination shall be evidenced by a resolution of the Board of Directors of
the Company) of the portion of the assets, evidence of indebtedness, Excess Cash
Dividends or securities so distributed applicable to one share of Common Stock.
Such adjustment shall be made whenever any such distribution is made, and shall
become effective on the date of distribution retroactive to the record date for
the determination of shareholders entitled to receive such distribution.

                  (e) Expiration of Rights, Options and Conversion Privileges.
Upon the expiration of any rights, options, warrants or conversion or exchange
privileges that have previously resulted in an adjustment hereunder, if any
thereof shall not have been exercised, the Exercise Price and the number of ADRs
or Warrant Shares issuable upon the exercise of each Warrant shall, upon such
expiration, be readjusted and shall thereafter, upon any future exercise, be
such as they would have been had they been originally adjusted (or had the
original adjustment not been required, as the case may be) as if (i) the only
shares of Common Stock so issued were the shares of Common Stock, if any,
actually issued or sold upon the exercise of such rights, options, warrants or
conversion or exchange rights and (ii) such shares of Common Stock, if any, were
issued or sold for the consideration actually received by the Company upon such
exercise plus the consideration, if any, actually received by the Company for
issuance, sale or grant of all such rights, options, warrants or conversion or
exchange rights whether or not exercised; provided, however, that no such
readjustment shall have the effect of increasing the Exercise Price by an
amount, or decreasing the number of ADRs or Warrant Shares issuable upon
exercise of each Warrant by a number, in excess of the amount or number of the
adjustment initially made in respect to the issuance, sale or grant of such
rights, options, warrants or conversion or exchange rights.

                  (f) De Minimis Adjustments. No adjustment in the number of
ADRs or Warrant Shares purchasable hereunder shall be required unless such
adjustment would require an increase or decrease of at least one percent (1%) in
the number of ADRs or Warrant Shares purchasable upon the exercise of each
Warrant; provided, however, that any adjustments which by reason of this 
Section 4.1(f) are not required to be made shall be
<PAGE>   31
                                       26

carried forward and taken into account in any subsequent adjustment. All
calculations shall be made to the nearest one-thousandth of a share.

                  (g) Adjustment of Exercise Price. Whenever the number of ADRs
or Warrant Shares purchasable upon the exercise of each Warrant is adjusted, as
herein provided, the Exercise Price per ADR or Warrant Share payable upon
exercise of such Warrant shall be adjusted (calculated to the nearest US$.0001)
so that it shall equal the price determined by multiplying such Exercise Price
immediately prior to such adjustment by a fraction the numerator of which shall
be the number of ADRs or Warrant Shares purchasable upon the exercise of each
Warrant immediately prior to such adjustment and the denominator of which shall
be the number of shares so purchasable immediately thereafter.

                  (h) Consolidation, Merger, Etc. (i) Subject to the provisions
of subsection (ii) below of this Section 4.1(h), in case of the consolidation of
the Company with, or merger of the Company with or into, or of the sale of all
or substantially all of the properties and assets of the Company to, any Person,
and in connection therewith consideration is payable to holders of shares of
Common Stock (or other securities or property purchasable upon exercise of
Warrants) in exchange therefor, the Warrants shall remain subject to the terms
and conditions set forth in this Agreement and each Warrant shall, after such
consolidation, merger or sale, entitle the Holder to receive upon exercise the
number of shares of capital stock or other securities or property (including
cash) of the Company, or of such Person resulting from such consolidation or
surviving such merger or to which such sale shall be made or of the parent of
such Person, as the case may be, that would have been distributable or payable
on account of the ADRs or Warrant Shares (or other securities or property
purchasable upon exercise of Warrants) if such Holder's Warrants had been
exercised immediately prior to such merger, consolidation or sale (or, if
applicable, the record date therefor); and in any such case the provisions of
this Agreement with respect to the rights and interests thereafter of the
Holders of Warrants shall be appropriately adjusted by the Board of Directors in
good faith so as to be applicable, as nearly as may reasonably be, to any shares
of stock or other securities or any property thereafter deliverable on the
exercise of the Warrants.

                  (ii) Notwithstanding the foregoing, if the Company merges or
consolidates with, or sells all or substantially all of its property and assets
to, another Person (other than an Affiliate of the Company) and consideration is
payable to holders of Common Stock in exchange for their Common Stock in
connection with such merger, consolidation or sale which consists solely of
cash, then the Holders of Warrants shall be entitled to receive distributions on
the date of such event on an equal basis with holders of Common Stock (or other
securities issuable upon exercise of the Warrants) as if the Warrants had been
exercised immediately prior to such event, less the Exercise Price. Upon receipt
of such payment, if any, the rights of a Holder shall terminate and cease and
such Holder's Warrants shall expire. In case of any such merger, consolidation
or sale of assets, the surviving or
<PAGE>   32
                                       27

acquiring Person shall deposit promptly with the Warrant Agent the funds, if
any, necessary to pay the Holders of the Warrants. After receipt of such deposit
from such Person or the Company, and after receipt of surrendered Warrant
Certificates, the Warrant Agent shall make payment by delivering a check in such
amount as is appropriate to such Person or Persons as it may be directed in
writing by the Holder surrendering such Warrants.

                  (i) Adjustments at Discretion of the Board of Directors; When
No Adjustment Required. In addition to the foregoing adjustments, the Board of
Directors of the Company may make any other adjustment to increase the number of
ADRs or Warrant Shares issuable upon exercise of Warrants or to decrease the
Exercise Price as it may, in good faith, deem desirable to protect the rights
and benefits of Holders. Notwithstanding any other provision of this Section 
4.1, no adjustment in the Exercise Price need be made for a transaction referred
to in subsections (a), (b), (c), (d) or (e) above (1) in respect of rights to
purchase Common Stock pursuant to a Company plan for reinvestment of dividends
or interest or pursuant to compensation plans for directors, officers and
employees in the ordinary course of business and (2) to the extent that Holders
are to receive cash compensation in U.S. dollars or compensation in securities
or property, in an amount, and in a manner, that the Board of Directors
determines to be fair and appropriate and comparable to the compensation they
would have received had they exercised the Warrants prior thereto, provided,
however, that such compensation to the Holders in securities or property will
not subject the Holder to any registration or other regulatory requirements or
subject the Holder to any adverse tax consequences other than the payment of
applicable taxes with respect to the receipt of such securities or property. To
the extent the Warrants become convertible into cash, no adjustment need be made
thereafter as to the cash. Interest will not accrue on the cash.

                  (j) Selection of Independent Financial Expert. If the services
of an Independent Financial Expert are required to determine the Current Market
Value, the Current Market Value shall be deemed to be equal to the value set
forth in a Value Report as determined by an Independent Financial Expert, which
shall be selected by the Board of Directors not more than ten Business Days
following the occurrence of any event referred to in subsections 4.1(b), 4.1(c)
or 4.1(d), and retained on customary terms and conditions, using one or more
valuation methods that the Independent Financial Expert, in its best
professional judgment, determines to be most appropriate, but without giving
effect to any discount for lack of liquidity, the fact that the Company may have
no class of equity securities registered under the Exchange Act or the fact that
the ADRs, Warrant Shares and other securities or property issuable upon exercise
of the Warrants represent a minority interest in the Company. Within two
calendar days after such selection of the Independent Financial Expert, the
Company shall deliver to the Warrant Agent a notice setting forth the name of
such Independent Financial Expert. The Company shall cause the Independent
Financial Expert to deliver a Value Report to the Company, and the Company shall
deliver to the Warrant Agent, within 45 calendar days of the appointment of the
Independent
<PAGE>   33
                                       28

Financial Expert, a Value Certificate attaching the Value Report. The Warrant
Agent shall have no duty with respect to the Value Report of any Independent
Financial Expert, except to keep it on file and available for inspection by the
Holders. The determination as to Current Market Value in accordance with the
provisions of this Section 4.1(j) shall be conclusive on all Persons.

                  Section 4.2. Decrease in Exercise Price. The Board of
Directors of the Company, in its sole discretion, shall have the right at any
time, or from time to time, to decrease the Exercise Price of the Warrants, such
reduction of the Exercise Price to be effective for a period or periods to be
determined by it, but in no event for a period of less than 30 calendar days.
Any exercise by the Board of Directors of any rights granted in this Section 4.2
must be preceded by a written notice from the Company to each Holder of the
Warrants and to the Warrant Agent setting forth the reduction in the Exercise
Price, which notice shall be mailed at least 30 calendar days prior to the
effective date of such decrease in the Exercise Price of the Warrants. Any
reduction of the Exercise Price pursuant to provisions of this Section 4.2 shall
not alter or adjust the number of ADRs, Warrant Shares or shares of other
securities issuable upon the exercise of the Warrants.

                  Section 4.3. Notice of Adjustment. Whenever the number of
ADRs, Warrant Shares or other stock or property purchasable upon the exercise of
each Warrant or the Exercise Price is adjusted, as herein provided (including
pursuant to Section 3.1), the Company shall promptly notify the Warrant Agent of
such adjustment in writing and shall cause the Warrant Agent promptly to mail,
by first-class mail, postage prepaid, at the expense of the Company, to each
Holder notice of such adjustment or adjustments and shall deliver to the Warrant
Agent a certificate of a firm of independent public accountants selected by the
Board of Directors of the Company (who may be the regular accountants employed
by the Company or its statutory auditors) setting forth the number of ADRs,
Warrant Shares or other stock or property purchasable upon the exercise of each
Warrant and the Exercise Price after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such certificate shall be
conclusive evidence of the correctness of such adjustment. The Warrant Agent
shall be entitled to rely on such certificate and shall be under no duty or
responsibility with respect to any such certificate, except to exhibit the same,
from time to time, to any Holder desiring an inspection thereof during
reasonable business hours. The Warrant Agent shall not at any time be under any
duty or responsibility to any Holders to determine whether any facts exist which
may require any adjustment of the Exercise Price or the number of ADRs, Warrant
Shares or other stock or property purchasable on exercise of the Warrants, or
with respect to the validity, nature or extent of any such adjustment when made,
or with respect to the method employed in making such adjustment, or the
validity or value (or the kind or amount) of any ADRs, Warrant Shares or other
stock or property which may be purchasable on exercise of the Warrants. The
Warrant Agent shall not be responsible for any failure of the Company to make
any cash payment or to issue, transfer or deliver any
<PAGE>   34
                                       29

ADRs, Warrant Shares or stock certificates or other common stock or properties
upon the exercise of any Warrant.

                  Section 4.4. Statement on Warrants. Irrespective of any
adjustment in the Exercise Price or the number or kind of shares purchasable
upon the exercise of the Warrants, Warrants theretofore or thereafter issued may
continue to express the same price and number and kind of shares as are stated
in the Warrants initially issuable pursuant to this Agreement.

                  Section 4.5. Notice of Consolidation, Merger, Etc. In case at
any time after the Issue Date and prior to 5:00 p.m., New York City time, on the
Expiration Date, there shall be any (i) consolidation or merger involving the
Company or sale, transfer or other disposition of all or substantially all of
the Company's property, assets or business (except a merger or other
reorganization in which the Company shall be the surviving corporation and
holders of Common Stock (or other securities or property purchasable upon
exercise of the Warrants) receive no consideration in respect of their shares)
or (ii) any other transaction contemplated by Section 4.1(h)(ii) above, then in
any one or more of such cases, the Company shall cause to be mailed to the
Warrant Agent and each Holder of a Warrant, at the earliest practicable time
(and, in any event, not less than 20 calendar days before any date set for
definitive action), notice of the date on which such reorganization, sale,
consolidation or merger shall take place, as the case may be. Such notice shall
also set forth such facts as shall indicate the effect of such action (to the
extent such effect may be known at the date of such notice) on the Exercise
Price and the kind and amount of the Common Stock and other securities, money
and other property deliverable upon exercise of the Warrants. Such notice shall
also specify the date as of which the holders of record of the Common Stock or
other securities or property issuable upon exercise of the Warrants shall be
entitled to exchange their shares for securities, money or other property
deliverable upon such reorganization, sale, consolidation or merger, as the case
may be.

                  Section 4.6. Fractional Interests. The Company shall not be
required to issue fractional shares of Class B Common Stock and the ADR
Depositary shall not be required to issue fractional ADRs on the exercise of
Warrants. If more than one Warrant shall be presented for exercise at the same
time by the same Holder, the number of ADRs or Warrant Shares which shall be
issuable upon such exercise thereof shall be computed on the basis of the
aggregate number of ADRs or Warrant Shares purchasable on exercise of the
Warrants so presented. If any fraction of a ADR or Warrant Share would, except
for the provisions of this Section 4.6, be issuable on the exercise of any
Warrant (or specified portion thereof), the Company shall pay an amount in cash
calculated by it to be equal to the then Current Market Value per ADR or share
of Class B Common Stock multiplied by such fraction computed to the nearest
whole cent. Notwithstanding anything contained in this Section 4.6, if the
Company is required to comply with laws or regulations in connection with
payment of cash in lieu of fractional shares, such laws or regulations shall
govern the making of such
<PAGE>   35
                                       30

payment. The Company shall immediately notify the Warrant Agent in writing if
any such laws or regulations shall require the Company to supplement or amend
this Agreement or to modify or amend the procedures or manner of such payment or
any other provisions set forth herein and the Warrant Agent shall not be
responsible or liable for making any such determination, complying with any such
laws or regulations or for the failure of the Company to so notify the Warrant
Agent.

                                    ARTICLE V

                WARRANT TRANSFER BOOKS; RESTRICTIONS ON TRANSFER

                  Section 5.1. Transfer and Exchange. The Warrant Certificates
shall be issued in registered form only. The Company shall cause to be kept at
the office of the Warrant Agent a register in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Warrant Certificates and transfers or exchanges of Warrant Certificates as
herein provided. All Warrant Certificates issued upon any registration of
transfer or exchange of Warrant Certificates shall be the valid obligations of
the Company, evidencing the same obligations, and entitled to the same benefit
under this Agreement, as the Warrant Certificates surrendered for such
registration of transfer or exchange.

                  A Holder may transfer its Warrants only by complying with the
terms of this Agreement. No such transfer shall be effected until, and such
transferee shall succeed to the rights of a Holder only upon, final acceptance
and registration of the transfer by the Warrant Agent in the register. Prior to
the registration of any transfer of Warrants by a Holder as provided herein, the
Company, the Warrant Agent, any agent of the Company or the Warrant Agent may
treat the Person in whose name the Warrants are registered as the owner thereof
for all purposes and as the Person entitled to exercise the rights represented
thereby, any notice to the contrary notwithstanding. Furthermore, any Holder of
a Global Warrant, shall, by acceptance of such Global Warrant, agree that
transfers of beneficial interests in such Global Warrant may be effected only
through a book-entry system maintained by the Holder of such Global Warrant (or
its agent), and that ownership of a beneficial interest in the Warrants
represented thereby shall be required to be reflected in a book entry. When
Warrant Certificates are presented to the Warrant Agent with a request to
register the transfer or to exchange them for an equal amount of Warrants of
other authorized denominations, the Warrant Agent shall register the transfer or
make the exchange in accordance with the provisions hereof.

                  Section 5.2. Registration, Registration of Transfer and
Exchange. Each Warrant shall initially be issued as part of a Unit consisting of
US$1,000 principal amount at maturity of Notes and four Warrants. Prior to the
Separation Date, the Warrants may not be
<PAGE>   36
                                       31

transferred or exchanged separately from, but may be transferred or exchanged
only together with, the Notes attached to such Warrants. Prior to the Separation
Date, the Trustee under the Indenture shall act as transfer agent ("Transfer
Agent") for both the Warrants and the Notes. Any request for transfer of a
Warrant prior to the Separation Date to the Transfer Agent shall be accompanied
by the Note attached thereto and the Transfer Agent will not execute any such
transfer without such Note attached thereto. Such Note will be duly endorsed and
accompanied by a written instrument of transfer in form satisfactory to the
Company, duly executed by the Holder thereof or the Holder's attorneys duly
authorized in writing. The Company shall provide notice to the Transfer Agent
and the Warrant Agent of the Separation Date five Business Days prior to such
date and the Transfer Agent will notify DTC of such date.

                  When Certificated Warrants are presented to the Warrant Agent
with a request from the Holder of such Warrants to register the transfer or to
exchange them for an equal number of Warrants of other authorized denominations,
the Warrant Agent shall register the transfer or make the exchange as requested;
provided that every Warrant presented and surrendered for registration of
transfer or exchange shall be duly endorsed and be accompanied by a written
instrument of transfer in form satisfactory to the Company, duly executed by the
Holder thereof or the Holder's attorneys duly authorized in writing.

                  To permit registrations of transfers and exchanges, the
Company shall make available to the Warrant Agent a sufficient number of
executed Warrant Certificates to effect such registrations of transfers and
exchanges. No service charge shall be made to the Holder for any registration of
transfer or exchange of Warrants, but the Company may require from the
transferring or exchanging Holder payment of a sum sufficient to cover any
transfer tax or similar governmental charge payable upon exchanges pursuant to
Section 2.4 and exchanges in respect of portions of Warrants not exercised or
ADRs or Warrant Shares not repurchased pursuant to Section 3.3 or 3.5 and the
Company may deduct such taxes from any payment of money to be made and such
transfer or exchange shall not be consummated (if such taxes are not deducted in
full) unless or until the Holder shall have paid to the Company the amount of
such tax or shall have established to the satisfaction of the Company and the
Warrant Agent that such tax has been paid.

                  Section 5.3. Book-Entry Provisions for the Rule 144A Global
Warrant and Regulation S Global Warrant. (a) The Rule 144A Global Warrant and
Regulation S Global Warrant initially shall (i) be registered in the name of DTC
or the nominee of DTC, (ii) be delivered to the Warrant Agent as custodian for
DTC and (iii) bear legends as set forth in Section 2.3 hereof. Members of, or
participants in, DTC ("Agent Members") shall have no rights under this Agreement
with respect to the Rule 144A Global Warrant or Regulation S Global Warrant, as
the case may be, held on their behalf by DTC or the Warrant Agent as its
custodian, and DTC may be treated by the Company, the Warrant Agent and any
agent of the Company or the Warrant Agent as the absolute owner of such Rule
144A Global Warrant
<PAGE>   37
                                       32

or Regulation S Global Warrant, as the case may be, for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Warrant Agent or any agent of the Company or the Warrant Agent from giving
effect to any written certification, proxy or other authorization furnished by
DTC or impair, as between DTC and its Agent Members, the operation of customary
practices governing the exercise of the rights of a beneficial owner of any
Warrants.

                  (b) Transfers of the Rule 144A Global Warrant and the
Regulation S Global Warrant shall be limited to transfers of such Rule 144A
Global Warrant or Regulation S Global Warrant in whole, but not in part, to DTC,
its successors or their respective nominees. Interests of beneficial owners in
the Rule 144A Global Warrant and the Regulation S Global Warrant may be
transferred in accordance with the rules and procedures of DTC and the
provisions of Section 5.4 hereof. Restricted Certificated Warrants and Offshore
Certificated Warrants shall be transferred to all beneficial owners in exchange
for their beneficial interests in the Rule 144A Global Warrant or the Regulation
S Global Warrant, respectively, if (i) DTC notifies the Company that it is
unwilling or unable to continue as Depositary for the Rule 144A Global Warrant
or the Regulation S Global Warrant, as the case may be, or DTC ceases to be a
"Clearing Agency" registered under the Exchange Act and a successor depositary
is not appointed by the Company within 90 days.

                  (c) Any beneficial interest in one of the Global Warrants that
is transferred to a Person who takes delivery in the form of an interest in the
other Global Warrant will, upon transfer, cease to be an interest in such Global
Warrant and become an interest in the other Global Warrant and, accordingly,
will thereafter be subject to all transfer restrictions, if any, and other
procedures applicable to beneficial interests in such other Global Warrant for
as long as it remains such an interest.

                  (d) In connection with any transfer pursuant to paragraph (b)
of this Section of a portion of the beneficial interests in the Rule 144A Global
Warrant to beneficial owners who are required to hold Restricted Certificated
Warrants, the Warrant Agent shall reflect on its books and records the date and
a decrease in the principal amount at maturity of the Rule 144A Global Warrant
in an amount equal to the principal amount at maturity of the beneficial
interest in the Rule 144A Global Warrant to be transferred, and the Company
shall execute, and the Warrant Agent shall countersign and deliver, one or more
Restricted Certificated Warrants of like tenor and amount.

                  (e) In connection with the transfer of the entire Rule 144A
Global Warrant or Regulation S Global Warrant to beneficial owners pursuant to
paragraph (b) of this Section , the Rule 144A Global Warrant or the Regulation S
Global Warrant, as the case may be, shall be deemed to be surrendered to the
Warrant Agent for cancellation, and the Company shall execute, and the Warrant
Agent shall countersign and deliver, to each beneficial owner identified by DTC
in exchange for its beneficial interest in the Rule 144A
<PAGE>   38
                                       33

Global Warrant or the Regulation S Global Warrant, as the case may be,
Restricted Certificated Warrants or Offshore Certificated Warrants, as the case
may be, of authorized denominations representing, in the aggregate, the number
of Warrants theretofore represented by the Rule 144A Global Warrant or the
Regulation S Global Warrant.

                  (f) Any Restricted Certificated Warrant delivered in exchange
for an interest in a Global Warrant pursuant to paragraph (b) or (d) of this
Section shall, except as otherwise provided by paragraph (a) of Section 5.4
hereof, bear the legend regarding transfer restrictions set forth in Exhibits B
and H hereto.

                  (g) The registered holder of the Rule 144A Global Warrant and
the Regulation S Global Warrant may grant proxies and otherwise authorize any
Person, including Agent Members and persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this
Agreement or the Warrants.

                  (h) Beneficial owners of interests in a Global Warrant may
receive Certificated Warrants (which shall bear the legend set forth in Exhibits
B and H if required by Section 2.2) in accordance with the procedures of DTC. In
connection with the execution, countersigning and delivery of such Certificated
Warrants, the Warrant Agent shall reflect on its books and records a decrease in
the principal amount at maturity of the relevant Global Warrant equal to the
principal amount at maturity of such Certificated Warrants and the Company shall
execute and the Warrant Agent shall countersign and deliver one or more
Certificated Warrants representing, in the aggregate, the number of Warrants
theretofore represented by the Global Warrant.

                  Section 5.4. Special Transfer Provisions. Unless and until an

         stating, or has otherwise advised the Company and the Warrant Agent in

                  (c) Transfers of Interest in the Regulation S Global Warrant
or Offshore Certificated Warrants to U.S. Persons. With respect to any transfer
of interests in the Regulation S Global Warrant or Offshore Certificated
Warrants to U.S. Persons:

                  (i) on or prior to the date that is 40 calendar days after the

                  (e) Private Placement Legend. Upon the transfer, exchange or
replacement of Warrant Certificates not bearing the Private Placement Legend,
the Warrant Agent shall deliver Warrant Certificates that do not bear the

satisfactory to the Company to the effect that neither such legend nor the
related restrictions on transfer are required in order to maintain compliance
with the provisions of the Securities Act.
<PAGE>   41
                                       36

                  (f) General. By its acceptance of any Warrants represented by
a Warrant Certificate bearing the Private Placement Legend, each Holder of such
Warrants acknowledges the restrictions on transfer of such Warrants set forth in
this Agreement and in the Private Placement Legend and agrees that it will
transfer such Warrants only as provided in this Agreement. The Warrant Agent
shall not register a transfer of any Warrants unless such transfer complies with
the restrictions on transfer of such Warrants set forth in this Agreement. In
connection with any transfer of Warrants, each Holder agrees by its acceptance
of Warrants to furnish the Warrant Agent or the Company such certifications,
legal opinions or other information as either of them may reasonably require to
confirm that such transfer is being made pursuant to an exemption from, or a
transaction not subject to, the registration requirements of the Securities Act;
provided that the Warrant Agent shall not be required to determine (but may rely
on a determination made by the Company with respect to) the sufficiency of any
such certifications, legal opinions or other information.

                  (g) Records. The Warrant Agent shall retain copies of all
letters, notices and other written communications received pursuant to Section 
5.3 hereof or this Section 5.4. The Company shall have the right to inspect and
make copies of all such letters, notices or other written communications at any
reasonable time upon the giving of reasonable written notice to the Warrant
Agent.

                  Section 5.5. Surrender of Warrant Certificates. Any Warrant
Certificate surrendered for registration of transfer, exchange, exercise or
repurchase of the Warrants represented thereby shall, if surrendered to the
Company, be delivered to the Warrant Agent, and all Warrant Certificates
surrendered or so delivered to the Warrant Agent shall be promptly cancelled by
the Warrant Agent and shall not be reissued by the Company and, except as
provided in this Article V in case of an exchange or in Article III hereof in
case of the exercise or repurchase of less than all the Warrants represented
thereby or in case of a mutilated Warrant Certificate, no Warrant Certificate
shall be issued hereunder in lieu thereof. The Warrant Agent shall deliver to
the Company from time to time or otherwise dispose of such cancelled Warrant
Certificates as the Company may direct in writing.

                                   ARTICLE VI

                            COVENANTS OF THE COMPANY

                  Section 6.1. Reservation and Authorization. During the period
within which the Warrants may be exercised in accordance with this Agreement,
the Company will have authorized and reserved and will keep available for issue
upon exercise of Warrants as herein provided, such number of its authorized but
unissued shares of Common Stock (which will be issued as shares of Class B
Common Stock) or other securities of the Company deliverable upon exercise of
Warrants as will be sufficient to permit the exercise in full of all
<PAGE>   42
                                       37

outstanding Warrants and will cause appropriate evidence of ownership of such
shares of Class B Common Stock or other securities of the Company to be
delivered to any Holder or to such Holder's order in accordance with this
Agreement or the ADR Custodian, as the case may be, upon the Warrant Agent's
instruction for delivery upon the exercise of Warrants. The Company shall use
its best efforts to file and cause to be declared effective a Registration
Statement with respect to the Warrant Shares and to ensure that all such shares
of Class B Common Stock or any ADRs representing such shares will, at all times,
be duly approved for listing subject to official notice of issuance on each
securities exchange, if any, on which such ADRs or Class B Common Stock are then
listed. The Company will use its best efforts (i) to ensure that each of the
Company's shareholders waive, with respect to the Warrant Shares, their right of
first refusal under the Bylaws, (ii) to ensure that the Bylaws are amended to
eliminate the shareholders' preemptive right and right of first refusal with
respect to the Warrant Shares, and (iii) to obtain all other necessary corporate
and governmental approvals, in each case on or prior to the Exercise
Commencement Date. The Company covenants to promptly notify the Warrant Agent in
writing when (A) all of the Company's shareholders have waived, with respect to
the Warrant Shares, their preemptive right and right of first refusal under the
Bylaws, and (B) the Bylaws have been amended to eliminate the shareholders'
right of first refusal with respect to the Warrant Shares. The Company covenants
that all shares of Class B Common Stock or other securities of the Company that
may be issued upon the exercise of the Warrants will, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free from
preemptive rights and all taxes, liens, charges and security interests with
respect to the issue thereof.

                  Section 6.2. Qualification Under Colombian Law. (a) The
Company shall use its best efforts to obtain, on or prior to the Exercise
Commencement Date, all Colombian corporate and governmental approvals and
authorizations, including, without limitation, (i) the approval of the Colombian
Ministry of Communications to permit the reduction of the equity percentage of
the shareholders which have qualified as "operators" in Colombia and (ii) any
necessary authorization or approval required for the Company to amend its Bylaws
to eliminate the preemptive right and right of first refusal of shareholders
with respect to the Class B Common Stock, necessary to issue the Warrant Shares
and any ADRs representing such shares and to file and cause to be declared
effective the Warrant Shares Registration Statement. The Company shall promptly
notify the Warrant Agent in writing when (A) the Company has obtained all
necessary Colombian corporate and governmental approvals and authorizations set
forth in this paragraph (a) of Section 6.2, and (B) such approvals and
authorizations thereafter cease to be in effect.

                  (b) Subject to the proviso of Section 6.3(a), the Company
shall use its best efforts to obtain all Colombian corporate and governmental
approvals and authorizations, including, without limitation, the approval of the
Colombian Superintendency of Securities, necessary to issue the ADRs and to file
and cause to be declared effective the ADR Registration Statement. The Company
shall promptly notify the Warrant Agent in writing
<PAGE>   43
                                       38

when (A) the Company has obtained all necessary Colombian corporate and
governmental approvals and authorizations set forth in this paragraph (b) of
Section 6.2, and (B) such approvals and authorizations thereafter cease to be in
effect.

                  Section 6.3. Establishment of ADR Program. (a) The Company
shall use its best efforts to establish and maintain a facility for the deposit
of the Warrant Shares and the issuance of ADRs in compliance with the terms of
paragraph (b) of this Section 6.3; provided, however, that if, and for so long
as, direct listing or admission for trading of the Warrant Shares on the New
York Stock Exchange, the American Stock Exchange or the Nasdaq Stock Market can
be obtained without the imposition of restrictions under Colombian law on the
holders of Warrant Shares greater than those, if any, imposed on holders of
ADRs, and a certificate signed by the President and the General Counsel of the
Company certifying to such effect is delivered to the Warrant Agent, the Company
will be relieved of its obligation to establish and maintain an ADR facility.

                  (b) The Company shall enter into a deposit agreement
containing substantially the terms set forth herein and in the section entitled
"Description of American Depositary Receipts" contained in the Offering
Memorandum, dated May 31, 1996, relating to the sale of the Units (the "ADR
Deposit Agreement") and comply with the provisions thereof. In addition,
following the execution of the ADR Deposit Agreement and the effective date of
the ADR Registration Statement, the Company shall, upon receipt of any notice
from the Warrant Agent of the exercise of any Warrant, deposit the Warrant
Shares for which such Warrant is exercisable in the name of the deposit agent
under the ADR Deposit Agreement (the "ADR Depositary"). The Company shall not
amend, modify or in any way alter the terms of the ADR Deposit Agreement (except
for changes approved pursuant to the ADR Deposit Agreement to the extent that
any ADRs owned by the Company are not included in the calculation of any vote,
consent or approval of any such changes), or grant any consent or waiver from
any of such terms, except for amendments, waivers or consents for the purposes
of curing any ambiguities, defects or inconsistencies, and for any such
amendment, waiver or consent that does not adversely affect the interests of any
Holder of the Warrants. The Company shall promptly notify the Warrant Agent in
writing on the date that the Company has entered into an ADR Deposit Agreement.
Notwithstanding the foregoing, the Company shall be relieved of all the
obligations set forth in this Section 6.3(b) if it is not obligated to establish
and maintain an ADR Facility pursuant to Section 6.3(a).

                  Section 6.4. Filing and Effectiveness of Warrant Shares
Registration Statement. (a) The Company shall use its best efforts to file
pursuant to Rule 415 under the Securities Act and cause to be declared effective
on or prior to the Exercise Commencement Date, a shelf registration statement on
the appropriate form (such shelf registration statement, including the
Prospectus, any amendments and supplements to such shelf registration statement,
including post-effective amendments, and all exhibits and all material
incorporated by reference in such registration statement being the "Warrant
Shares Registration
<PAGE>   44
                                       39

Statement") covering the issuance of the Underlying Securities upon exercise of
the Warrants.

                  (b) (i) The Company shall use its best efforts to keep such
Warrant Shares Registration Statement continuously effective until the earlier
of such time as all Warrants have been exercised and the Expiration Date.

                  (ii) Notwithstanding the foregoing, the Company may suspend
the use of the Warrant Shares Registration Statement (and the ADR Registration
Statement) for a period not to exceed 30 days in any three-month period or for a
period not to exceed an aggregate of 60 days in any 12-month period, except in
either case during the 30-day period immediately prior to the Expiration Date,
for valid business reasons (not including avoidance of the Company's obligations
hereunder), including the acquisition or divestiture of assets, public filings
with the Commission, pending corporate developments and similar events (any such
period a "Suspension Period").

                  (iii) The Company will promptly notify the Warrant Agent in
writing (A) on the date that the Warrant Shares Registration Statement is
declared effective, (B) on any date that the Commission issues a stop order
suspending the effectiveness of such Warrant Shares Registration Statement, (C)
on any date that any such stop order ceases to be effective and (D) of the
commencement and termination of any Suspension Period. The Company will furnish
the Warrant Agent with current Prospectuses meeting the requirements of the
Securities Act and the rules and regulations of the Commission thereunder in
sufficient quantity to permit the Warrant Agent to deliver a Prospectus to each
Holder of a Warrant upon the exercise thereof.

                  Section 6.5. Registration Rights in Initial Public Offering.
(a) If the Company proposes to file a registration statement with the Commission
relating to a public offering that would constitute the Company's Initial Public
Offering if closed (such registration statement, including the Prospectus, any
amendments and supplements to such registration statement, including
post-effective amendments, and all exhibits and all material incorporated by
reference in such registration statement being the "IPO Registration Statement"
and, together with the Warrant Shares Registration Statement, each a
"Registration Statement"), the Company shall include all outstanding Warrants in
the IPO Registration Statement relating to the public offering, provided that
the Company shall not be obligated to include (1) any Warrants that may then be
offered and sold by a person that is not an affiliate of the Company pursuant to
Rule 144 without compliance with the provisions of Rule 144(e)(2), (2) any
Warrants that were included in any previous Registration Statement, (3) any
Warrants held by any person that is an affiliate of the Company or (4) any
Warrants held by a person that does not comply with the obligations set forth in
the Section 6.5(b). The Company shall promptly notify the Warrant Agent in
writing on the date that the IPO Registration Statement is declared effective.
The Company will furnish the Warrant

                                       40

Agent with current Prospectuses meeting the requirements of the Securities Act
and the rules and regulations of the Commission thereunder in sufficient
quantity to permit the Warrant Agent to deliver a Prospectus to each Holder of a
Warrant upon the sale or exercise thereof.

                  (b) No Holder may include any of its Underlying Securities or
Warrants in any Registration Statement pursuant to this Agreement unless and
until such Holder furnishes to the Company in writing, within 10 Business Days
after receipt of a written request therefor (which also describes the effect of
any failure to respond), such information as the Company may reasonably request
for use in connection with any Registration Statement or Prospectus included
therein and in any application to the NASD. No Holder shall be entitled to
liquidated damages pursuant to Section 7.1 hereof unless and until such Holder
shall have provided all such reasonably requested information and such Holder
shall not be entitled to liquidated damages with respect to any period during
which such information was required to have been but was not so provided.

                  Section 6.6. Registration of ADRs. Subject to the proviso of
Section 6.3(a), in connection with the filing of a Registration Statement, the
Company shall cause the ADR Depositary to use its best efforts to cause to be
filed a registration statement on the appropriate form (any such registration
statement, including the Prospectus, any amendments and supplements to such
registration statement, including post-effective amendments, and all exhibits
and all material incorporated by reference in such registration statement being
the "ADR Registration Statement") covering the issuance of the ADRs upon
exercise of the Warrants and shall cause the ADR Depositary to use its best
efforts to cause such ADR Registration Statement to be declared effective on or
prior to the Exercise Commencement Date. Except as set forth in Section 
6.4(b)(ii), the Company shall cause the ADR Depositary to use its best efforts
to keep such ADR Registration Statement continuously effective until the earlier
of (i) such time as all Warrants have been exercised and (ii) the Expiration
Date. Prior to filing such ADR Registration Statement or any amendment or
supplement thereto, the Company shall cause the ADR Depositary to provide a copy
thereof to the Initial Purchasers and their counsel and afford them a reasonable
time to comment thereon.

                  Section 6.7. Blue Sky. The Company shall use its best efforts
to register or qualify the Underlying Securities under all applicable securities
or "blue sky" laws of all jurisdictions in the United States in which any Holder
of Warrants may or may be deemed to purchase Underlying Securities upon the
exercise of Warrants and shall use its best efforts to maintain such
registration or qualification through the earlier of the date upon which all
Warrants have been exercised and the Expiration Date; provided, however, that
the Company shall not be required to (i) qualify as a foreign corporation or as
a dealer in securities in any jurisdiction where it would not otherwise be
required to qualify but for this Section 6.7, (ii) file any general consent to
service of process or (iii) subject itself to taxation in any jurisdiction if it
is not otherwise so subject.

                  Section 6.8. Accuracy of Disclosure. The Company and its
successors represent and warrant to each Holder and agree for the benefit of
each Holder that (i) any Registration Statement and the documents incorporated
by reference therein will not contain any untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein not
misleading and (ii) the Prospectus delivered to such Holder upon its exercise of
the Warrants and the documents incorporated by reference therein will not
contain any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, provided that such representation shall
not apply to statements in or omissions from any Registration Statement and the
documents incorporated by reference therein or the Prospectus contained therein
and the documents incorporated by reference therein or any amendment or
supplement thereto made in reliance upon and in conformity with written
information furnished to the Company through a representative by or on behalf of
such Indemnified Party specifically for use therein.

                  Section 6.9. Indemnity. The Company hereby indemnifies each
beneficial owner of a Warrant (whether or not it is, at the time the indemnity
provided for in this Section 6.9 is sought, such a beneficial owner) (each, an
"Indemnified Party") against all losses, damages or liabilities which such
beneficial owner suffers as a result of any breach, on the date of any exercise
of a Warrant by such beneficial owner, of the representations, warranties or
agreements contained in Section 6.8; provided, however, that the Company shall
not be liable in any such case to the extent that any such loss, claim, damage,
liability or action arises out of or is based upon an untrue statement in or
omission or alleged omission from any Registration Statement and the documents
incorporated by reference therein or the Prospectus contained therein and the
documents incorporated by reference therein or any amendment or supplement
thereto made in reliance upon and in conformity with written information
furnished to the Company through a representative by or on behalf of such
Indemnified Party specifically for use therein.

                  Section 6.10. Expenses. All expenses incident to the Company's
performance of or compliance with its obligations under this Agreement will be
borne by the Company, regardless of whether a Registration Statement becomes
effective, including without limitation: (i) all Commission, stock exchange or
National Association of Securities Dealers, Inc. registration and filing fees,
(ii) all fees and expenses incurred in connection with compliance with state
securities or "blue sky" laws, (iii) all expenses of any Persons incurred by or
on behalf of the Company in preparing or assisting in preparing, word
processing, printing and distributing any Registration Statement, any
Prospectus, any amendments or supplements thereto and other documents relating
to the performance of and compliance with this Agreement, (iv) all rating agency
fees, (v) the fees and disbursements of the Warrant Agent, (vi) the fees and
disbursements of the ADR Depositary, (vii) all fees and disbursements relating
to any required Colombian governmental authorizations and approvals, (viii) the
fees and disbursements of counsel for the Company and (ix) the fees and
<PAGE>   47
                                       42

disbursements of the independent public accountants of the Company, including
the expenses of any special audits or "cold comfort" letters required by or
incident to such performance and compliance.

                                   ARTICLE VII

                                    REMEDIES

                  Section 7.1. Liquidated Damages. (a) The Company and the
Initial Purchasers agree that the Holders of the Warrants will suffer damages if
a Warrant Registration Default occurs and that it would not be feasible to
ascertain the extent of such damages with precision. Accordingly, if a Warrant
Registration Default occurs, then the Company agrees to pay, or cause to be
paid, to the Holder of each Warrant, as liquidated damages and not as a penalty,
cash in the amount of US$0.03 per week, or portion thereof, for the first 90-day
period during which the Warrant Registration Default continues beginning on the
Exercise Commencement Date in the case of clause (i) of the definition of
Warrant Registration Default, and on the date of the order suspending
effectiveness of the Warrant Shares Registration Statement in the case of clause
(ii) of the definition of Warrant Registration Default. Such amount shall
increase by US$0.02 per week, or portion thereof, at the beginning of each
subsequent 90-day period during which a Warrant Registration Default continues
up to a maximum aggregate additional amount of US$0.07 per week. Upon the cure
of all Warrant Registration Defaults, such liquidated damages will cease to
accrue.

                  (b) The Company shall notify the Warrant Agent in writing
within three Business Days after each and every date on which an event occurs in
respect of which liquidated damages are required to be paid (an "Event Date").
The Company shall pay the liquidated damages due on the Warrants by depositing
with the Warrant Agent, in trust, for the benefit of the Holders thereof, on or
before the applicable liquidated damages payment date specified below,
immediately available funds in sums sufficient to pay the liquidated damages
then due. The liquidated damages amount due shall be payable on each March 15
and September 15 commencing on the Exercise Commencement Date (the "liquidated
damages payment dates") to Holders of record of Warrants on the close of
business on the immediately preceding March 1 or September 1, as the case may
be. Each obligation to pay liquidated damages shall be deemed to accrue on the
applicable Event Date. The parties hereto agree (for themselves and for the
benefit of Holders from time to time of Warrants) that the liquidated damages
provided for in this Section 7.1 constitute a reasonable estimate of the damages
that may be incurred by Holders of Warrants by reason of the occurrence of the
failure of the Company to fulfill its obligations to register the Warrant
Shares.

                  Section 7.2. Payment of Additional Amounts. Any and all
payments made by the Company pursuant to Section 7.1 will be made free and clear
of and without deduction for or on account of any and all present or future
taxes, levies, imposts, deductions, charges or withholdings and all liabilities
with respect thereto imposed by Colombia or any political subdivision thereof
excluding any taxes, levies, imposts, deductions, charges or withholdings and
all liability with respect thereto (i) resulting from the Holder having some
connection with Colombia or any political subdivision thereof other than the
mere holding of or enforcement of such Warrant, (ii) the payment of which may be
avoided by the Holder complying with any certification, declaration or other
reporting requirement concerning the nationality, residence, identity or
connection with any taxing authority of such Holder as the beneficial owner of
such Warrant, (iii) in the nature of estate, inheritance, gift, sale, transfer,
personal property or similar taxes or (iv) imposed on or with respect to any
payment by the Company to the Holder if such Holder is a fiduciary or
partnership or person other than the sole beneficial owner of such payment to
the extent such tax, levy, impost, deduction, charge or withholding would not
have been imposed on a beneficiary or settlor with respect to such fiduciary,
member of such partnership or the beneficial owner of such payment had such
beneficiary, settlor, member or beneficial owner been the Holder of such Warrant
(all such non-excluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities being referred to collectively or individually as "Colombian
Withholding Taxes"). If the Company is required by law to deduct any Colombian
Withholding Taxes from or in respect of any amount payable under Section 7.1,
the sum payable thereunder shall be increased by the amount necessary so that
after making all required deductions the Holder will receive an amount equal to
the sum it would have received had no such deductions been made (such additional
amounts to be paid by the Company in accordance with the foregoing being
"Additional Amounts"). At least 30 calendar days prior to each date on which any
payment under or with respect to Section 7.1 is due and payable, if the Company
will be obligated to pay Additional Amounts with respect to such payment, the
Company will deliver to the Warrant Agent an officers' certificate (x) stating
the fact that such Additional Amounts will be payable and the amounts so payable
and certifying the amount required to be withheld on such date; (y) certifying
that the Company shall withhold such amount on such date and shall pay such
amount with any required penalty or interest to the appropriate governmental
authorities; and (z) setting forth such other information necessary to enable
the Warrant Agent to pay such Additional Amounts to Holders on the payment date.
The Company agrees to indemnify the Warrant Agent for and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith
on its part arising out of or in connection with actions taken or omitted by it
in reliance on any certificate furnished pursuant to this Section 7.2 or the
failure of the Company to furnish any such certificate. The obligations of the
Company under this Section 7.2 shall survive the resignation or removal of the
Warrant Agent and termination of this Agreement and the payment of all amounts
under or with respect to Section 7.1.
<PAGE>   49
                                       44

                  Section 7.3. Default Interest. If the Company shall fail to
pay to any Holder the Warrant Repurchase Price pursuant to Section 3.4, the
Repurchase Price pursuant to Section 3.5, or cash in lieu of fractional ADRs or
Warrant Shares pursuant to Section 4.6, in each case if and as when required by
the terms of this Agreement, the Company shall be obligated to pay interest on
such amount at a rate per annum equal to 14% from the date of the default to the
date of payment, which interest shall compound quarterly.

                  Section 7.4. Remedies; No Waiver. Notwithstanding any other
provision of this Agreement, if a Default occurs and is continuing, the Holders
of the Warrants may pursue any available remedy to collect the Repurchase
Obligation or to enforce the performance of any provision of this Agreement. A
delay or omission by any Holder of a Warrant in exercising, or a failure to
exercise, any right or remedy arising out of a Default shall not impair the
right or remedy or constitute a waiver of or acquiescence in the Default. All
remedies are cumulative to the extent permitted by law.

                                  ARTICLE VIII

                                THE WARRANT AGENT

                  Section 8.1. Duties and Liabilities. The Company hereby
appoints the Warrant Agent to act as agent of the Company as set forth in this
Agreement. The Warrant Agent hereby accepts the agency established by this
Agreement and agrees to perform the same upon the terms and conditions herein
set forth, by all of which the Company and the Holders of Warrants, by their
acceptance thereof, shall be bound. The Warrant Agent shall not have any
obligation towards or relationship of agency or trust for the Holders, except as
provided in Section 7.1(b) and Section 10.1 hereof. The Warrant Agent shall not,
by countersigning Warrant Certificates or by any other act hereunder, be deemed
to make any representations as to the validity or authorization of the Warrants
or the Warrant Certificates (except as to its countersignature thereon) or of
any securities or other property delivered upon exercise or repurchase of any
Warrant, or as to the accuracy of the computation of the Exercise Price or the
number or kind or amount of stock or other securities or other property
deliverable upon exercise or repurchase of any Warrant, or as to the
independence of any Independent Financial Expert or the correctness of the
representations of the Company made in the certificates that the Warrant Agent
receives or the validity, sufficiency or adequacy of any offering materials. The
Warrant Agent shall not be accountable for the use or application by the Company
of the proceeds of the exercise of any Warrant. The Warrant Agent shall not have
any duty to calculate or determine any adjustments with respect to either the
Exercise Price or the kind and amount of shares or other securities or any
property receivable by Holders upon the exercise or repurchase of Warrants
required from time to time and the Warrant Agent shall have no duty or
responsibility in determining the accuracy or correctness of such calculation.
The Warrant Agent shall not (a) be liable for any recital
<PAGE>   50
                                       45

or statement of fact contained herein or in the Warrant Certificates or for any
action taken, suffered or omitted by it in good faith in the belief that any
Warrant Certificate or any other documents or any signatures are genuine or
properly authorized, (b) be responsible for any failure on the part of the
Company to comply with any of its covenants and obligations contained in this
Agreement or in the Warrant Certificates or (c) be liable for any act or
omission in connection with this Agreement except for its own negligence or
willful misconduct. The Warrant Agent is hereby authorized to accept
instructions with respect to the performance of its duties hereunder from the
President, any Vice President or the Secretary or Treasurer of the Company and
to apply to any such officer for instructions (which instructions will be
promptly given in writing when requested) and the Warrant Agent shall not be
liable for any action taken or suffered to be taken by it in good faith in
accordance with the instructions of any such officer; however, in its
discretion, the Warrant Agent may in lieu thereof accept other evidence of such
or may require such further or additional evidence as it may deem reasonable.
The Warrant Agent shall not be liable for any action taken with respect to any
matter in the event it requests instructions from the Company as to that matter
and does not receive such instructions within a reasonable period of time after
the request therefor.

                  The Warrant Agent may execute and exercise any of the rights
and powers hereby vested in it or perform any duty hereunder either itself or by
or through its attorneys, agents or employees, and the Warrant Agent shall not
be answerable or accountable for any act, default, neglect or misconduct of any
such attorneys, agents or employees, provided reasonable care has been exercised
in the selection and in the continued employment of any such attorney, agent or
employee. The Warrant Agent shall not be under any obligation or duty to
institute, appear in or defend any action, suit or legal proceeding in respect
hereof, unless first indemnified to its satisfaction, but this provision shall
not affect the power of the Warrant Agent to take such action as the Warrant
Agent may consider proper, whether with or without such indemnity. The Warrant
Agent shall promptly notify the Company in writing of any claim made or action,
suit or proceeding instituted against it arising out of or in connection with
this Agreement.

                  The Warrant Agent may rely and shall be fully protected in
acting or refraining from acting upon any certificate, notice, instruction,
Warrant, document or other writing believed by it to be genuine and to have been
signed or presented by the proper Person. The Warrant Agent need not investigate
any fact or matter stated in any such certificate, notice, instruction, Warrant,
document or other writing. The Warrant Agent shall not be liable for any action
that it takes or omits to take in good faith which it believes to be authorized
or within its rights or powers.

                  The Company will perform, execute, acknowledge and deliver or
cause to be performed, executed, acknowledged and delivered all such further
acts, instruments and
<PAGE>   51
                                       46

assurances as are consistent with this Agreement and as may reasonably be
required by the Warrant Agent in order to enable it to carry out or perform its
duties under this Agreement.

                  The Warrant Agent shall act solely as agent of the Company
hereunder. The Warrant Agent shall not be liable except for the failure to
perform such duties as are specifically set forth herein, and no implied
covenants or obligations shall be read into this Agreement against the Warrant
Agent, whose duties and obligations shall be determined solely by the express
provisions hereof.

                  With respect to the identity of beneficial owners of interests
in the Global Warrants and the number of Warrants beneficially owned by any
beneficial owner, the Warrant Agent shall be entitled to conclusively rely on
the records of DTC and shall be fully protected in so relying.

                  Section 8.2. Right to Consult Counsel. The Warrant Agent may
at any time consult with legal counsel acceptable to it (who may be legal
counsel for the Company), and the opinion or advice of such counsel shall be
full and complete authorization and protection to the Warrant Agent and the
Warrant Agent shall incur no liability or responsibility to the Company or to
any Holder for any action taken, suffered or omitted by it in good faith in
accordance with the opinion or advice of such counsel.

                  Section 8.3. Compensation; Indemnification. The Company agrees
to pay to the Warrant Agent from time to time compensation for all services
rendered by it hereunder as the Company and the Warrant Agent may agree in
writing from time to time, and to reimburse the Warrant Agent for reasonable
expenses and disbursements incurred in connection with the execution and
administration of this Agreement (including the reasonable fees and the expenses
of its counsel), and further agrees to indemnify the Warrant Agent for, and to
hold it harmless against, any claim, loss, liability or expense arising out of
or in connection with the acceptance and administration of this Agreement,
including the costs and expenses of defending itself against any such claim or
liability, except that the Company shall have no liability hereunder to the
extent that any such loss, liability or expense results from the Warrant Agent's
own negligence or willful misconduct. If the Company is required by law to
deduct Colombian Withholding Taxes from or in respect of any sum payable to the
Warrant Agent under this Section 8.3, such sum shall be increased by the amount
necessary so that after making all necessary deductions, the Warrant Agent will
receive an amount equal to the sum it would have received had no such deductions
been made. The obligations of the Company under this Section 8.3 shall survive
the exercise and the expiration of the Warrants and the resignation or removal
of the Warrant Agent. No provision of this Agreement shall require the Warrant
Agent to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder or in the exercise of any of
its rights or powers if it shall have reasonable grounds for believing that
<PAGE>   52
                                       47

repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

                  Section 8.4. No Restrictions on Actions. The Warrant Agent and
any stockholder, director, officer or employee of the Warrant Agent may buy,
sell or deal in any of the Warrants or other securities of the Company or become
pecuniarily interested in transactions in which the Company may be interested,
or contract with or lend money to the Company or otherwise act as fully and
freely as though it were not the Warrant Agent under this Agreement. Nothing
herein shall preclude the Warrant Agent from acting in any other capacity for
the Company or for any other legal entity.

                  Section 8.5. Discharge or Removal; Replacement Warrant Agent.
Except as otherwise provided in this Section 8.5, no resignation or removal of
the Warrant Agent and no appointment of a successor warrant agent shall become
effective until the acceptance of appointment by the successor warrant agent
provided herein. The Warrant Agent may resign from its position as such and be
discharged from all further duties and liabilities hereunder (except liabilities
arising as a result of the Warrant Agent's own negligence or willful
misconduct), after giving one month's prior written notice to the Company. The
Company may remove the Warrant Agent upon one month's prior written notice
specifying the date when such discharge shall take effect, and the Warrant Agent
shall thereupon in like manner be discharged from all further duties and
liabilities hereunder, except as aforesaid. The Warrant Agent or the Company
shall cause to be mailed (by first-class mail, postage prepaid) to each Holder
of a Warrant a copy of said notice of resignation or notice of removal, as the
case may be. Upon such resignation or removal the Company shall appoint in
writing a new warrant agent. If the Company shall fail to make such appointment
within a period of 30 calendar days after it has been notified in writing of
such resignation by the resigning Warrant Agent or after such removal, then the
resigning Warrant Agent or the Holder of any Warrant may apply to any court of
competent jurisdiction for the appointment of a new warrant agent. Any new
warrant agent, whether appointed by the Company or by such a court, shall be a
bank or trust company doing business under the laws of the United States or any
state thereof, in good standing and having a combined capital and surplus of not
less than US$50,000,000. The combined capital and surplus of any such new
warrant agent shall be deemed to be the combined capital and surplus as set
forth in the most recent annual report of its condition published by such
warrant agent prior to its appointment, provided that such reports are published
at least annually pursuant to law or to the requirements of a federal or state
supervising or examining authority. After acceptance in writing of such
appointment by the new warrant agent, it shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named herein as
the Warrant Agent, without any further assurance, conveyance, act or deed;
however, the original Warrant Agent, upon payment of its fees and expenses,
shall in all events deliver and transfer to the successor Warrant Agent all
property, if any, at the time held hereunder by the original Warrant Agent and
if for any reason it shall be necessary or expedient to execute and deliver any
further
<PAGE>   53
                                       48

assurance, conveyance, act or deed, the same shall be done at the expense of the
Company and shall be legally and validly executed and delivered by the resigning
or removed Warrant Agent. Not later than the effective date of any such
appointment, the Company shall file a notice thereof with the resigning or
removed Warrant Agent and shall forthwith cause a copy of such notice to be
mailed to each Holder of a Warrant. Failure to give any notice provided for in
this Section 8.5, however, or any defect therein, shall not affect the legality
or validity of the resignation of the Warrant Agent or the appointment of a new
warrant agent, as the case may be.

                  Section 8.6. Successor Warrant Agent. Any corporation into
which the Warrant Agent or any successor warrant agent may be merged or
converted, or any corporation resulting from any consolidation to which the
Warrant Agent or any successor warrant agent shall be a party, and any
corporation which acquires substantially all of the corporate trust business of
the Warrant Agent, shall be a successor Warrant Agent under this Agreement
without any further act, provided that such corporation would be eligible for
appointment as successor to the Warrant Agent under the provisions of Section 
8.5 hereof. Any such successor Warrant Agent shall promptly cause notice of its
succession as Warrant Agent to be mailed (by first-class mail, postage prepaid)
to each Holder of a Warrant.

                                   ARTICLE IX

                                 WARRANT HOLDERS

                  Section 9.1. Warrant Holder Not Deemed a Stockholder. The
Company and the Warrant Agent may deem and treat the registered Holder(s) of the
Warrant Certificates as the absolute owner(s) thereof (notwithstanding any
notation of ownership or other writing thereon made by anyone), for the purpose
of any exercise thereof and for all other purposes, and neither the Company nor
the Warrant Agent nor any agent of the Company or the Warrant Agent shall be
affected by any notice to the contrary. Prior to the exercise of the Warrants,
no Holder of a Warrant Certificate, as such, shall be entitled to any rights of
a stockholder of the Company, including, without limitation, the right to vote
or to consent to any action of the stockholders, to receive dividends or other
distributions, to exercise any preemptive right or to receive any notice of any
meeting of stockholders and, except as otherwise provided in this Agreement,
shall not be entitled to receive any notice of any proceedings of the Company.

                  Section 9.2. Right of Action. All rights of action with
respect to this Agreement are vested in the Holders of the Warrants, and any
Holder of any Warrant, without the consent of the Warrant Agent or the Holder of
any other Warrant, may, on such Holder's own behalf and for such Holder's own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company suitable to enforce, or otherwise
<PAGE>   54
                                       49

in respect of, such Holder's right to exercise, exchange or tender for purchase
such Holder's Warrants in the manner provided in the Warrant Certificate
representing his Warrants and in this Agreement.

                                    ARTICLE X

                                  MISCELLANEOUS

                  Section 10.1. Money Deposited with the Warrant Agent. The
Warrant Agent shall not be required to pay interest on any moneys deposited
pursuant to the provisions of this Agreement except such as it shall agree in
writing with the Company to pay thereon. Any moneys, securities or other
property which at any time shall be deposited by the Company or on its behalf
with the Warrant Agent pursuant to this Agreement shall be and are hereby
assigned, transferred and set over to the Warrant Agent in trust for the purpose
for which such moneys, securities or other property shall have been deposited;
but such moneys, securities or other property need not be segregated from other
funds, securities or other property except to the extent required by law. The
Warrant Agent shall distribute any money deposited with it for payment and
distribution to the Holders by mailing by first-class mail a check in such
amount as is required by this Agreement to each such Holder at the address shown
on the Warrant register of the Company, or as it may be otherwise directed in
writing by such Holder, in accordance with the terms and conditions hereof. Any
money, securities or other property deposited with the Warrant Agent for payment
or distribution to the Holders that remains unclaimed for two years after the
date the money, securities or other property was deposited with the Warrant
Agent shall be delivered to the Company upon its written request therefor.

                  Section 10.2. Payment of Taxes. All ADRs, Warrant Shares or
other securities issuable upon the exercise of Warrants shall be validly issued,
fully paid and nonassessable, and the Company shall pay any stamp, registration,
and other similar taxes and other governmental charges that may be imposed under
the laws of the United States of America, Colombia or any political subdivision
or taxing authority thereof or therein in respect of the issue or delivery
thereof or of other securities deliverable upon exercise of Warrants or in
respect of any Warrant Repurchase or Repurchase Offer (other than income taxes
imposed on the Holders). The Company shall not be required, however, to pay any
tax or other charge imposed in connection with any transfer involved in the
issue of any ADR certificate, Warrant Share certificate or other securities or

Company hereby waives irrevocably, to the extent permitted by law, any objection
to the laying of venue in New York, New York, and any claim of inconvenient
forum in respect of any such action in New York, New York to which it might
otherwise be entitled in any actions arising out of or based on this Agreement
or any Warrants.

                  To the extent that the Company has or hereafter may acquire

aid of execution, execution or otherwise) with respect to itself or its
property, it hereby irrevocably waives such immunity in respect of its

Currency") other than U.S. Dollars and as a result of any variation as between
(i) the rate of exchange at which the U. S. Dollar amount is converted into the

amount of the Judgment Currency actually received by such Person. The foregoing
indemnity shall continue in full force and effect notwithstanding any such
judgment or order as aforesaid. The term "spot rate of exchange" shall include
any premiums and costs of exchange payable in connection with the purchase of,
or conversion into, U.S. Dollars.

                                       A-2

         This Warrant Certificate is issued under and in accordance with a
Warrant Agreement dated as of June 7, 1996 (the "Warrant Agreement"), between
the Company and The Bank of New York, as Warrant Agent, and is subject to the
terms and provisions contained therein, to all of which terms and provisions the
Holder of this Warrant Certificate consents by acceptance hereof. The Warrant
Agreement is hereby incorporated herein by reference and made a part hereof.
Reference is hereby made to the Warrant Agreement for a full description of the
rights, limitations of rights, obligations, duties and immunities thereunder of
the Company and the Holders of the Warrants. The summary of the terms of the
Warrant Agreement contained in this Warrant Certificate is qualified in its
entirety by express reference to the Warrant Agreement. All terms used in this
Warrant Certificate that are defined in the Warrant Agreement shall have the
meanings assigned to them in the Warrant Agreement.

         Copies of the Warrant Agreement are on file at the office of the
Warrant Agent and may be obtained by writing to the Warrant Agent at the
following address:

                           The Bank of New York
                           101 Barclay Street
                           New York, New York  10286

                           Attention:       Corporate Trust Administration

         After the Exercise Commencement Date, the Warrants may only be
exercised if (i) the Warrant Agent has received written notice from the Company
that a Registration Statement has been declared effective by the Commission with
respect to the Warrant Shares, (ii) the Warrant Agent has not received written
notice from the Company or the Commission that a stop order issued by the
Commission suspending the effectiveness of such Registration Statement is in
effect, (iii) the Warrant Agent has received written notice from the Company
that the Company has obtained all necessary Colombian corporate and governmental
authorizations and approvals set forth in Sections 6.1 and 6.2(a) of the Warrant
Agreement, (iv) the Warrant Agent has not received written notice from the
Company that the authorizations and approvals referred to in clause (iii) are
not in effect and (v) the Warrant Agent has not received notice from the Company
of any Suspension Period permitted under Section 6.4(b)(ii) of the Warrant
Agreement.

         A "Warrant Registration Default" shall be deemed to have occurred if
(i) on the Exercise Commencement Date, the Warrant Shares Registration Statement
has not been declared effective by the Commission, or (ii) the Commission shall
have issued a stop order suspending the effectiveness of the Warrant Shares
Registration Statement, at a time when such Warrant Shares Registration
Statement is required to be kept effective by the Company pursuant to the
provisions of the Warrant Agreement.
<PAGE>   62
                                       A-3

         If a Warrant Registration Default occurs, then the Company shall pay,
or cause to be paid, to the holder of each Warrant cash in the amount of US$0.03
per week, or portion thereof, for the first 90-day period during which the
Warrant Registration Default continues. Such amount shall increase by US$0.02
per week, or portion thereof, at the beginning of each subsequent 90-day period
during which a Warrant Registration Default continues up to a maximum aggregate
additional amount of US$0.07 per week. Such amount due shall be payable on each
March 15 and September 15 commencing on the Exercise Commencement Date (the
"liquidated damages payment dates") to holders of record of Warrants on the
close of business on the immediately preceding March 1 or September 1, as the
case may be.

         Except as provided in the Warrant Agreement, the Warrants shall be
exercisable only for Warrant Shares if, at the time such Warrants are exercised,
the Warrant Agent has not received written notice that the Company has entered
into an ADR Deposit Agreement and that all Colombian corporate and governmental
authorizations set forth in Section 6.2(b) of the Warrant Agreement have been
obtained or if the Warrant Agent has received written notice from the Company
that any of the authorizations and approvals set forth in Section 6.2(b) of the
Warrant Agreement is not in effect. Except as provided in the Warrant Agreement,
the Warrants shall be exercisable only for ADRs if, at the time such Warrants
are exercised, (i) the Warrant Agent has received written notice that the
Company has entered into an ADR Deposit Agreement and all Colombian corporate
and governmental authorizations set forth in Section 6.2(b) of the Warrant
Agreement have been obtained and (ii) the Warrant Agent has not received written
notice from the Company that any of the authorizations and approvals set forth
in Section 6.2(b) of the Warrant Agreement is not in effect.

         If, on the date of exercise of any Warrant, the Peso Equivalent of the
Exercise Price is less than the aggregate of the par value of the Warrant Shares
represented by the ADRs or the Warrant Shares, as the case may be, for which
such Warrant may be exercised, the Exercise Price payable upon such exercise
shall be adjusted to be equal to the Peso Equivalent of the aggregate of such
par value.

         If a Trading Market does not exist for the Warrant Shares or the ADRs
on the Expiration Date (or, in certain circumstances set forth in the Warrant
Agreement, the next preceding day which is a trading day and on which trading in
securities of such type is not limited (the "Preceding Trading Day")), the
Company shall repurchase all outstanding Warrants that have not been exercised
on, or prior to the Expiration Date (a "Warrant Repurchase").

         Warrants received by the Warrant Agent in proper form in a Warrant
Repurchase will, except as otherwise provided in the Warrant Agreement, be
repurchased by the Company at a price in cash equal to the value on the
Expiration Date (or the Preceding
<PAGE>   63
                                       A-4

Trading Date, if applicable) of the ADRs, Warrant Shares and other securities or
property of the Company which would have been delivered upon exercise of
Warrants had the Warrants been exercised (regardless of whether the Warrants are
then exercisable), less the Exercise Price for such Warrant in effect on the
Expiration Date as provided in the Warrant Agreement (the "Warrant Repurchase
Price"). The value of such ADRs, Warrant Shares and other securities shall be
determined by the Independent Financial Expert (as defined in the Warrant
Agreement), in the manner set forth in the Warrant Agreement.

         If a Trading Market does not exist for the Warrant Shares or the ADRs
on the Expiration Date or, in the circumstances described in the Warrant
Agreement, the Preceding Trading Day, the Company must offer to repurchase all
ADRs and Warrant Shares outstanding on the Expiration Date and, to the extent
there is no Trading Market therefor, all other securities issued upon exercise
of the Warrants or distributed in respect of the Warrant Shares that are then
held by the holder of such ADRs and Warrant Shares (a "Repurchase Offer"). If
the Company makes a Repurchase Offer, Holders may, until the expiration date of
such offer, surrender all or part of their ADRs or Warrant Shares (together with
such other securities issued or distributed in respect of such ADRs or Warrant
Shares) for repurchase by the Company.

         ADRs and Warrant Shares and other such securities referred to in the
preceding paragraph received by the Warrant Agent in proper form during a
Repurchase Offer will, except as otherwise provided in the Warrant Agreement, be
repurchased by the Company at a price in cash equal to the value on the
Expiration Date (or the Preceding Trading Date, if applicable) of the ADRs or
Warrant Shares and other such securities subject to a Repurchase Offer, as the
case may be. The value of such ADRs or Warrant Shares and other such securities
shall be determined by the Independent Financial Expert (as defined in the
Warrant Agreement), in the manner set forth in the Warrant Agreement.

         If the Company fails to pay to a Holder the Warrant Repurchase Price or
the Repurchase Price as required by the Warrant Agreement, it shall be obligated
to pay interest on such amount at a rate per annum of 14% from the date of the
default to the date of payment, which interest shall compound quarterly.

         If the Company merges or consolidates with or into, or sells all or
substantially all of its property and assets to, another Person solely for cash,
the Holders of Warrants shall be entitled to receive distributions on the date
of such event on an equal basis with holders of shares of Class B Common Stock
(or other securities issuable upon exercise of the Warrants) as if the Warrants
had been exercised immediately prior to such event (less the Exercise Price) and
the Warrants shall expire upon such payment.

         The number of ADRs or Warrant Shares purchasable upon the exercise of
each Warrant and the price per ADR or Warrant Share are subject to adjustment as
provided in
<PAGE>   64
                                       A-5

the Warrant Agreement. Except as stated in the immediately preceding paragraph,
in the event the Company merges or consolidates with, or sells all or
substantially all of its assets to, another Person, each Warrant will, upon
exercise, entitle the Holder thereof to receive the number of shares of capital
stock or other securities or the amount of money and other property that would
have been distributable or payable on account of the ADRs or Warrant Shares (or
other securities or property issuable upon exercise of a Warrant) if such
Warrants had been exercised prior to completion of such merger, consolidation or
sale.

         As to any final fraction of an ADR or Warrant Share which the same
Holder of one or more Warrant Certificates would otherwise be entitled to
purchase upon exercise thereof in the same transaction, the Company shall pay
the cash value thereof determined as provided in the Warrant Agreement.

         All Warrant Shares or other securities issuable by the Company upon the
exercise of Warrants shall be validly issued, fully paid and nonassessable, and
the Company shall pay all stamp, registration or other similar taxes and other
governmental charges that may be imposed under the laws of the United States of
America, Colombia or any political subdivision or taxing authority thereof or
therein in respect of the issue or delivery of such shares or of other
securities deliverable upon exercise of Warrants. The Company shall not be
required, however, to pay any tax or other charge imposed in connection with any
transfer involved in the issue of any ADR certificate, Warrant Share certificate
or other securities or property issuable upon the exercise of the Warrants or in
respect of a Warrant Repurchase, Repurchase Offer or payment of cash to any
Person other than the Holder of a Warrant Certificate surrendered upon the
exercise or repurchase of a Warrant, and in case of such transfer or payment,
the Warrant Agent and the Company may deduct such taxes from any payment of
money to be made and shall not be required to issue any ADR certificate, Warrant
Shares certificate or stock certificate until such tax or charge has been paid
or it has been established to the Warrant Agent's and the Company's satisfaction
that no such tax or other charge is due.

         Subject to the restrictions on transfer set forth in Article V of the
Warrant Agreement, this Warrant Certificate and all rights hereunder are
transferable by the registered Holder hereof, in whole or in part, on the
register of the Company maintained by the Warrant Agent for such purpose at its
office in New York, New York, upon surrender of this Warrant Certificate duly
endorsed, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Warrant Agent duly executed, with signatures
guaranteed as specified in the attached Form of Assignment, by the registered
Holder hereof or his attorney duly authorized in writing and upon payment of any
necessary transfer tax or other governmental charge imposed upon such transfer.
Upon any partial transfer, the Company will issue and the Warrant Agent will
countersign and deliver to such Holder a new Warrant Certificate or Certificates
with respect to any portion not so transferred. Each taker and Holder of this

Attention:  Corporate Trust Administration

Ladies and Gentlemen:

         In connection with our proposed purchase of _______ Warrants to
Purchase Shares of Class B Common Stock (the "Warrants") of Occidente y Caribe
Celular S.A. (the "Company"), we confirm that:

                  1. We understand that the Warrants have not been registered
         under the Securities Act of 1933, as amended (the "Securities Act"),
         and may not be sold except as permitted in the following sentence. We
         agree on our own behalf and on behalf of any investor account for which
         we are purchasing the Warrants to offer, sell or otherwise transfer
         such Warrants prior to the date which is three years after the later of
         the date of original issue and the last date on which the Company or
         any affiliate of the Company was the owner of such Warrants, or any
         predecessor thereto (the "Resale Restriction Termination Date") only
         (a) to the Company, (b) pursuant to a registration statement which has
         been declared effective under the Securities Act, (c) for so long as
         the Warrants are eligible for resale pursuant to Rule 144A under the
         Securities Act, to a person we reasonably believe is a qualified
         institutional buyer under Rule 144A (a "QIB") that purchases for its
         own account or for the account of a QIB to whom notice is given that
         the transfer is being made in reliance on Rule 144A, (d) pursuant to
         offers and sales to non-U.S. Persons that occur outside the United
         States within the meaning of Regulations S under the Securities Act,
         (e) to an
<PAGE>   78
                                       E-2

         institutional "accredited investor" within the meaning of subparagraph
         (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act that is
         acquiring the Warrants for its own account or for the account of such
         an institutional "accredited investor" for investment purposes and not
         with a view to, or for offer or sale in connection with, any
         distribution thereof in violation of the Securities Act or (f) pursuant
         to any other available exemption from the registration requirements of
         the Securities Act, subject in each of the foregoing cases to any
         requirement of law that the disposition of our property and the
         property of such investor account or accounts be at all times within
         our or their control and to compliance with any applicable state
         securities laws. The foregoing restrictions on resale will not apply
         subsequent to the Resale Restriction Termination Date. If any resale or
         other transfer of the Warrants is proposed to be made pursuant to
         clause (e) above prior to the Resale Restriction Termination Date, the
         transferor shall deliver a letter from the transferee substantially in
         the form of this letter to the Warrant Agent, which shall provide,
         among other things, that the transferee is an institutional "accredited
         investor" within the meaning of subparagraph (a)(1), (2), (3) or (7) or
         Rule 501 under the Securities Act and that it is acquiring such
         Warrants for investment purposes and not for distribution in violation
         of the Securities Act. We acknowledge that the Company and the Warrant
         Agent reserve the right prior to any offer, sale or other transfer
         prior to the Resale Restriction Termination Date of the Warrants
         pursuant to clauses (d), (e) and (f) above to require the delivery of
         an opinion of counsel, certifications and/or other information
         satisfactory to the Company and the Warrant Agent.

                  2. We are an institutional "accredited investor" (as defined
         in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
         Act) purchasing for our own account or for the account of such an
         institutional "accredited investor," and we are acquiring the Warrants
         for investment purposes and not with a view to, or for offer or sale in
         connection with, any distribution in violation of the Securities Act
         and we have such knowledge and experience in financial and business
         matters as to be capable of evaluating the merits and risks of our
         investment in the Warrants, and we and any accounts for which we are
         acting are each able to bear the economic risk of our or its
         investment.

                  3. We are acquiring the Warrants purchased by us for our own
         account or for one or more accounts as to each of which we exercise
         sole investment discretion.

                  4. You are entitled to rely upon this letter and you are
         irrevocably authorized to produce this letter or a copy hereof to any
         interested party in any administrative or legal proceeding or official
         inquiry with respect to the matters covered hereby.
