  Transtel S.A. (the "Company" or "Transtel"), a Colombian corporation,
together with Transtel Pass Through Trust, a Delaware business trust (the
"Trust" or "Issuer"), created pursuant to the Trust Agreement of Transtel Pass
Through Trust, dated as of October 20, 1997 (the "Original Trust Agreement"),
hereby offers, upon the terms and subject to the conditions set forth in this
Prospectus and the accompanying letter of transmittal (the "Letter of
Transmittal," and together with this Prospectus, the "Exchange Offer"), to
exchange all outstanding 12 1/2% Pass Through Trust Certificates due 2007 (the
"Original Certificates"), issued by the Trust, for a like aggregate principal
amount of 12 1/2% Pass Through Exchange Certificates due 2007 (the "Exchange
Certificates") issued by the Trust, each representing a pro rata interest in
the $150.0 million aggregate principal amount of 12 1/2% Senior Notes due 2007
(the "Senior Notes"), issued by the Company. Both the Original Certificates and
the Exchange Certificates (together, the "Certificates") are guaranteed by the
Company. The Original Certificates and the Original Guarantee (as defined
herein) are collectively referred to herein as the "Original Securities" and
the Exchange Certificates and the Exchange Guarantee (as defined herein) are
collectively referred to herein as the "Exchange Securities." The terms of the
Exchange Securities are substantially identical to the terms of the Original
Securities, except that the Exchange Securities will have been registered under
the Securities Act of 1933, as amended (the "Securities Act"), and will not
contain terms restricting the transfer of such securities. For a complete
description of the Exchange Securities, see "Description of the Certificates"
and "Description of the Guarantees." The Company will not receive any cash
proceeds from, and will pay all expenses incident to, the Exchange Offer.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND

THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. ORIGINAL CERTIFICATEHOLDERS (AS DEFINED HEREIN) ARE URGED TO READ

WHETHER TO TENDER THEIR ORIGINAL CERTIFICATES PURSUANT TO THE EXCHANGE OFFER.
 
                                  -----------
 
                 The date of this Prospectus is April 10, 1998.

(Continued from previous page)
 
  The issuance of the Original Certificates and the purchase of the Senior
Notes by the Trust that occurred on October 28, 1997 are referred to herein as
the "Offering." The holders of Original Certificates (the "Original
Certificateholders") and the holders of the Exchange Certificates (the
"Exchange Certificateholders") are collectively referred to as the
"Certificateholders". The Certificates represent undivided beneficial
interests in the assets of the Trust. Wilmington Trust Company is the Pass
Through Trustee (the "Pass Through Trustee") of the Trust. The Trust exists
for the sole purpose of issuing and selling the Certificates, investing the
proceeds from the issuance of the Original Certificates in the Senior Notes,
registering the Exchange Securities under the Securities Act, exchanging the
Original Securities for Exchange Securities, and engaging in only those other
activities necessary or incidental thereto.
 
  The Senior Notes bear interest at a rate of 12 1/2% per annum payable
semiannually in cash on each May 1 and November 1 of each year (each referred
to herein as an "Interest Payment Date"), commencing May 1, 1998. Interest
distributions made on each May 1 and November 1 will be paid to the persons
who are the registered Certificateholders on the April 15 and October 15, as
the case may be, immediately preceding such Interest Payment Date. Each
Certificateholder will be entitled to receive a pro rata share of any payments
received by, or on behalf of, the Pass Through Trustee on behalf of the Trust
in respect of the Senior Notes.
 
  The Senior Notes are redeemable, in whole or in part, at the option of the
Company, on or after November 1, 2002, at the redemption prices set forth
herein plus accrued and unpaid interest to the date of redemption. In
addition, in the event of the sale by the Company of at least $25.0 million of
its Capital Stock (as defined herein) in one or more Public Equity Offerings
(as defined herein) or to one or more Strategic Equity Investors (as defined
herein), the Company may, at its option, use the net cash proceeds of such
sale or sales to redeem up to 35% of the Senior Notes at a redemption price
herein of the principal amount thereof plus accrued and unpaid interest to the
date of redemption. Upon a Change of Control (as defined herein), the Company
will be required to make an offer to repurchase the Senior Notes at a price
equal to 101% of the principal amount thereof, plus accrued and unpaid
interest, to the date of repurchase.
 
  The Trust will accept for exchange any and all Original Certificates that
are validly tendered on or prior to 5:00 p.m., New York City time, on the date
the Exchange Offer expires, which will be       , 1998, unless the Exchange
Offer is extended (the "Expiration Date"). Tenders of Original Certificates
may be withdrawn at any time prior to 5:00 p.m., New York City time, on the
Expiration Date. The Exchange Offer is not conditioned upon any minimum number
of Original Certificates being tendered for exchange.
 
  Any Original Certificates not tendered and accepted in the Exchange Offer
will remain outstanding and will be entitled to all the same rights and will
be subject to all the same limitations applicable thereto under the Trust
Agreement (except for certain rights to be registered under the Act which
terminate upon consummation of the Exchange Offer). Following consummation of
the Exchange Offer, all untendered and tendered but unaccepted Original
Certificates, if any, will continue to be subject to all of the existing
restrictions upon transfer provided thereon and neither the Company nor the
Trust will have any further obligation to such Original Certificateholders to
provide for registration under the Securities Act of the Original Certificates
held by them. To the extent that Original Certificates are not tendered and
accepted in the Exchange Offer, an Original Certificateholder's ability to
sell untendered and tendered but unaccepted Original Certificates could be
adversely affected. See "Risk Factors--Consequences of a Failure to Exchange
Original Certificates."
 
  Prior to this Exchange Offer, there has been no public market for the
Original Certificates and there can be no assurance that an active public or
private market for the Certificates will develop. The Company does not intend
to list the Certificates on any national securities exchange or to seek
admission thereof to trading on the National Association of Securities Dealers
Automated Quotation System. Even if a market for the Certificates should
develop, the Certificates could trade at a discount from their face value.
 
  THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, ORIGINAL CERTIFICATEHOLDERS IN ANY JURISDICTION
IN WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN
COMPLIANCE WITH THE SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.
 
  IN THIS PROSPECTUS, UNLESS OTHERWISE SPECIFIED OR THE CONTEXT OTHERWISE
REQUIRES, REFERENCES TO "PS" OR "PESOS" ARE TO COLOMBIAN PESOS, REFERENCES TO
"DOLLARS," "U.S. $" AND "$" ARE TO UNITED STATES DOLLARS AND THE TERMS "UNITED
STATES" AND "U.S." MEAN THE UNITED STATES OF AMERICA, ITS TERRITORIES,
POSSESSIONS AND ALL AREAS SUBJECT TO ITS JURISDICTION.

                      ENFORCEABILITY OF CIVIL LIABILITIES
 
  The Company is a sociedad anomina organized under the laws of Colombia. The
directors and officers of the Company and certain experts named in this
Prospectus reside outside of the United States, and all or a substantial
portion of the assets of such persons and of the Company are located outside
the United States. As a result, it may not be possible for the Pass Through
Trustee, the Indenture Trustee (as defined herein), Guarantee Trustee (as
defined herein) or the Certificateholders to effect service of process within
the United States upon such persons, including with respect to matters arising
under the Securities Act, or to enforce against the Company or any of such
persons judgments of courts of the United States predicated upon the civil
liability provisions of the federal securities laws of the United States or
under the Certificate Guarantees. The Company has been advised by its
Colombian legal counsel, Cavelier Abogados 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 this Exchange Offer and the
Certificate Guarantees. The Company has been advised by its Colombian legal
counsel that a claim by the Pass Through Trustee, the Indenture Trustee or a
United States Certificateholder in connection with this Exchange Offer or the
Certificate Guarantees may be brought in Colombian courts. See "Enforcement of
Foreign Judgments in Colombia."
 
                             AVAILABLE INFORMATION
 
  The Company has filed with the Commission under the Securities Act, a
registration statement (which term includes any amendments thereto) (the
"Registration Statement") on Form F-4, of which this Prospectus (the
"Prospectus") is a part, with respect to the Exchange Certificates offered
hereby. This Prospectus does not contain all the information set forth in or
annexed as an exhibit to the Registration Statement. Such additional
information, and other information filed by the Company, may be inspected and
copied at the public reference facilities maintained by the Commission at Room
1024, 450 Fifth Street, N.W., Washington, D.C. 20549, and at the regional
offices of the Commission maintained at 7 World Trade Center, Suite 1300, New
York, New York 10048 and Citicorp Center, 500 West Madison Street, Suite 1400,
Chicago, Illinois 60661-2511, at prescribed rates. The Commission also
maintains an Internet Web Site at http://www.sec.gov that contains reports and
other information. Statements contained in this Prospectus describing the
contents of any contract or other document referred to herein do not
necessarily describe such documents in their entirety, and in each instance
reference is made to the copy of such contract or other document filed as an
exhibit to the Registration Statement, each such statement being qualified in
all respects by such reference.
 
  No separate financial statements of the Trust have been included herein.
Neither the Company nor the Trust consider such financial statements material
to the Certificateholders because (i) the Trust has no independent operations
and exists for the sole purpose of issuing and selling the Certificates,
investing the proceeds from the issuance of the Original Certificates in the
Senior Notes issued by the Company, registering the Exchange Certificates
under the Securities Act, exchanging the Original Securities for Exchange
Securities, and engaging in only those other activities necessary or
incidental thereto, and (ii) the Company's obligations described herein to
provide certain indemnities in respect of, and be responsible for, certain
costs, expenses, debts and liabilities of the Trust under the Indenture and
any supplemental indenture thereto, the Certificate Guarantees, the Trust
Agreement and the Senior Notes, taken together, constitute a full and
unconditional guarantee of payments due on the Certificates. See "Description
of Securities."
 
  Neither the Company nor the Trust is currently subject to the information
reporting requirements of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). Upon the effectiveness of this Registration Statement, the
Company will become subject to such requirements, which will continue for so
long as the Company is required to do so pursuant to Section 15(d) of the
Exchange Act.

                          FORWARD-LOOKING STATEMENTS
 
  This Prospectus contains forward-looking statements. These forward-looking
statements reflect the Company's views with respect to future events and
financial performance. Actual results could differ materially from those
projected in the forward-looking statements as a result of the risk factors as
well as other factors discussed elsewhere herein. See "Risk Factors." The
words "believe," "expect" and "anticipate" and similar expressions identify
forward-looking statements. Readers are cautioned not to place undue reliance
on these forward-looking statements, which speak only as of their dates. The
Company undertakes no obligation to publicly update or revise any forward-
looking statements, whether as a result of new information, future events or
otherwise. Many factors could cause the Company's actual results to differ
materially from historical results or the results projected in the forward-
looking statements. Among these factors are those identified in "Risk Factors"
and "Management's Discussion and Analysis of Financial Condition and Results
of Operations."
 
                          MARKET AND POPULATION DATA
 
  Market data used throughout this Prospectus was obtained from internal
company surveys and industry publications. Industry publications generally
state that the information contained therein has been obtained from sources
believed to be reliable, but that the accuracy and completeness of such
information is not guaranteed. The Company has not independently verified this
market data. Similarly, internal company surveys, while believed by the
Company to be reliable, have not been verified by any independent sources.
 
  Data regarding population in Colombia are based on preliminary projections
of 1995 population figures calculated by the Departamento Administrativo
Nacional de Estadistica (National Administrative Department of Statistics)
("DANE") on the basis of the 1993 census. There can be no assurance that these
projections accurately reflect the current population in Colombia. Information
regarding subscriber penetration and line data in Colombia is derived from
information supplied by the Departamento Nacional de Planeacion (National
Planning Department) ("DNP") as of December 31, 1995.
 
                                EXCHANGE RATES
 
  Until 1991, the Banco de la Republica of Colombia (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 Superintendencia
Bancaria of Colombia (the "Superintendency of Banking") calculates and
publishes daily the representative market rate, which is the weighted average
of the 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 Dollars (the
"Representative Market Rate"). The Representative Market Rate serves as a
basis for many foreign exchange transactions conducted on the foreign exchange
market and the free market as defined under Law 9 of 1991. From October 1991
through January 1995, the Central Bank set the Official Rate for certain
limited purposes. Since February 1994, the Central Bank issues buy and sell
quotations that form a band within which the Representative Market Rate can
move freely.

  The following table sets forth the Official Rate at the end of each period
indicated and, for each such period, the high, low, average and end of period
Representative Market Rate. The Federal Reserve Bank of New York does not
report a noon buying rate for Pesos.

THE COMPANY
 
  The Company is the largest private telephone company in Colombia, providing
telephone services to both business and residential subscribers. The Company
(excluding TeleGirardot (as defined herein)) currently owns and operates
telephone systems serving seven cities, with an aggregate population of
approximately 2.9 million people, located in the southwestern region of
Colombia. As of December 31, 1997, such system provided service to an aggregate
of approximately 101,500 subscribers and had an average penetration of
approximately 18 lines per 100 people.
 
  On December 31, 1997, the Company acquired Empresa de Telecomunicaciones de
Girardot S.A. E.S.P. ("TeleGirardot"). The statistical, financial and other
data in this Prospectus does not include information regarding TeleGirardot,
except where specifically indicated. For information regarding TeleGirardot,
see "Prospectus Summary--Recent Developments" herein.
 
  In 1990, through the enactment of Decree 1900, Colombia's government
initiated the deregulation and privatization of the state-owned
telecommunications sector in order to promote competition and encourage private
investment and thereby improve service for its citizens. This was followed by
the enactment of Law 142 on July 11, 1994 ("Law 142"), which established the
basic guidelines and regulations to support the sector's privatization. Prior
to the enactment of Decree 1900, telephone service in Colombia had been
provided by the same government-owned entities that also provided other basic
utility services. Since most of these municipal entities lacked sufficient
capital, spending for basic utility services such as power and water often took
precedence over the delivery of telephone service. As a result, many of these
municipal service providers have failed to install sufficient capacity to
satisfy their customers' demand for telephone service. For those customers who
do currently receive telephone service through municipal service providers, the
municipal entities provide low-quality service and offer few, if any, of the
more commonly available value-added services.
 
  The Company was formed in August 1993 by certain members of the Caicedo
family, a prominent Colombian family, and Guillermo Lopez, the Company's
President and a Director, to take advantage of the opportunities created by
deregulation. Management's goal is to capitalize on the substantial demand for
telephone service which the Company believes exists throughout Colombia. This
belief is supported by the fact that Colombia's first and third largest cities,
Bogota and Medellin, respectively, where capital has been spent to meet
telephone demand, have recently achieved penetration in excess of 30 lines per
100 people, which is substantially higher than cities in the Company's service
area. The Company seeks to modernize and expand its telephone systems to
accommodate existing demand for telephone service and future growth.
 
  The Company's objective is to increase the penetration in each of its markets
and to provide high quality value-added telephone services to its subscribers.
For example, in May 1995, the Company, in conjunction with the local
municipality, acquired its first telephone system, the only system serving the
city of Palmira. At the time of the acquisition, this system had approximately
15,600 subscribers, representing a penetration of approximately 4.9 lines per
100 people. Following the acquisition, the Company initiated its Expansion Plan
(as defined herein) in Palmira, which consists of investing approximately $34.2
million to replace a portion of the
 
                                       6
<PAGE>
 
existing Palmira system's infrastructure, to upgrade the system with modern
equipment from Siemens A.G. ("Siemens") and to increase system capacity to
60,000 lines, which implies a penetration of 18.9 lines per 100 people. The
Company began offering telephone service in Palmira in September 1995 and, as a
result of the substantial demand, experienced immediate and significant
improvements in operating and financial results. Under the Company's
management, the Palmira system's subscriber base has grown by 220%, increasing
from approximately 15,600 at the time of acquisition to approximately 50,100 at
December 31, 1997. Subsequent to the acquisition of TelePalmira, the Company
acquired three additional operating companies, increasing its number of
subscribers from approximately 15,600 as of September 30, 1995 to approximately
101,500 as of December 31, 1997. In addition to the subscribers with installed
lines as of December 31, 1997, the Company had 20,966 additional customers who
have signed promissory notes for new lines to be installed.
 
  The Company is located at Calle 19N, No. 2-29, 40th Floor, Cali, Colombia,
and its telephone number is (572) 660-4860.
 
COLOMBIA AND COLOMBIAN TELEPHONY MARKET OVERVIEW
 
  Colombia is one of the oldest democracies and most stable economies in Latin
America and is one of only three countries in Latin America rated investment
grade by all three major rating agencies. Colombia has achieved positive real
economic growth every year since 1950 and averaged compounded annual growth in
Gross Domestic Product ("GDP") of approximately 4.7% from 1992 to 1996, one of
the highest growth rates in Latin America. Annual inflation has declined over
the past six years from 26.8% in 1991 to 17.7% in 1997. In recent years, the
Colombian government has encouraged foreign investment and exports through
reduced foreign exchange controls and lower import quotas and tariffs. The
Colombian government has also begun to open certain public services, such as
power and banking, to private sector investment and is considering other
sectors for privatization. In part as a result of these policies, net foreign
investment in Colombia has grown from $3.5 billion in 1990 to $10.5 billion in
1997. During the same period, Colombia has achieved increased diversification
of its export base and the value of its exports has grown from $6.7 billion to
$11.6 billion. See "Risk Factors--Colombian Political, Economic and Social
Risks."
 
  In 1995, Colombia had approximately 4.9 million installed lines, representing
a penetration of approximately 14.0 lines per 100 people, which generated
approximately $635 million of local telephony revenues, representing
approximately 44% of the $1.5 billion telecommunications industry.
Historically, local telephony has been treated as a utility. The local
telephony network is fragmented and approximately 30 municipal operators
service approximately 780 municipalities. Prior to deregulation, each municipal
operator had a monopoly in the region which it served and typically provided
limited and often marginal service. As a result, Colombia is significantly
underserved by existing wireline operators and demand for telephone service
substantially outweighs the supply of telephone lines. This is evidenced by
multi-year waiting lists and unsatisfied demand in Colombia for approximately
1.2 million telephone lines as estimated by the DNP. The DNP also projects that
the country's existing installed line network will need to more than double by
2007 in order to keep pace with growing demand.
 
  The Colombian government, recognizing the importance of an effective
telecommunications infrastructure and the role that the telecommunications
industry plays in national development, identified the problems in the
telecommunications industry and, from 1990 to 1994, established the regulatory
environment required to support private sector participation. The government
enacted decrees addressing many facets of operation including interconnection,
numbering and tariffs. The 1994 deregulation introduced competition and
established a tariff environment under which telephone service providers are
encouraged to compete on the basis of efficiency and service rather than price.
Tariffs for all telecommunication services are established and overseen by the
Comision de Regulacion de Telecomunicaciones (Telecommunications Regulatory
Commission) (the "CRT"), which allows operators to set prices based on either
the current or historical cost of providing service. See "Risk Factors--
Regulatory Risks."
 
                                       7
<PAGE>
 
 
  In 1995, the Colombian government announced its intention to open the long
distance market to competition. Until recently, domestic and international long
distance service was provided exclusively by Empresa Nacional de
Telecomunicaciones ("TELECOM"), a state-owned company, which had a monopoly on
international and long distance calls. The CRT has established a process under
which the opening of the long distance market to competition is to be reviewed.
The Company believes that the deregulation of the long distance market will, as
it has in other countries, serve to stimulate telephone usage, due to the fact
that price competition is likely to lower tariffs to the consumer. The Company
does not currently expect that it would qualify to be a new entrant into the
long distance market in the near future.

industry, see "Annex--Republic of Colombia" and "Industry Overview; Legal and
Regulatory Environment."
 
OPERATING COMPANIES
 
  The Company has acquired interests in existing wireline telephone systems
serving the cities of Palmira, Cartago, Popayan, Buga and their surrounding
areas, and built new systems serving the cities of Yumbo, Jamundi, Cali and
their surrounding areas. In each case the Company has joined with the local
municipality to form an operating company (each an "Operating Company") to own
and operate each telephone system. The Operating Companies are (i) Empresa de
Telefonos de Palmira S.A. E.S.P. ("TelePalmira"), which services the cities of
Palmira and Candelaria, (ii) Telefonos de Cartago S.A. E.S.P. ("TeleCartago"),
which services the city of Cartago, (iii) Caucatel S.A. E.S.P. ("Caucatel"),
which services the western section of the city of Popayan, (iv) Empresa de
Telefonos de Jamundi S.A. E.S.P. ("TeleJamundi"), which services the city of
Jamundi; (v) Bugatel S.A. E.S.P. ("Bugatel"), which services the city of Buga
and its surrounding regions; and (vi) Unitel S.A. E.S.P. ("Unitel"), which
operates a wireline system ("Unitel Wireline") in the city of Yumbo, a city
adjacent to Cali, and a fixed wireless system ("Unitel Wireless"), which
commenced operations in January, 1998, that services the city of Cali. In
addition, see "Prospectus Summary--Recent Developments" for a discussion of the
Company's acquisition of the telephone network of the municipality of Girardot
on December 31, 1997.

(1) Although installation of switching infrastructure and antennas was
    substantially completed at Unitel Wireless in the fourth quarter of 1997,
    there was an interference from unauthorized radio spectrum users which was
    subsequently removed by the Ministry of Communications. This delayed the
    Company's launch of operations at Unitel Wireless until the first quarter
    of 1998.
(2) In addition to the subscribers with installed lines at December 31, 1997,
    the Company has 20,966 additional customers who have signed promissory
    notes for new lines to be installed.
(3) Penetration at December 31, 1997 represents the number of installed lines
    per 100 people. In Cartago, Jamundi, Buga, Yumbo and Cali, penetration
    includes the installed lines of municipal competitors of approximately
    10,000 lines, 5,200 lines, 30,700 lines, 5,500 lines, and 386,800 lines as
    per the Company's estimates, respectively.
 
EXPANSION PLAN
 
  At the time of each acquisition, the Company's systems generally lacked
sufficient capacity to service the demand of their customers and utilized
antiquated technology to provide limited service to their customers. Based on
extensive market demand studies, the Company created an expansion plan (the
"Expansion Plan") which is designed to satisfy the significant demand for
telephone lines in each of its operating cities (excluding the cities serviced
by TeleGirardot). The Expansion Plan does not include TeleGirardot, for which a
separate expansion plan has been developed. Management intends to increase the
number of installed lines in its seven operating cities from an aggregate of
56,800, which serviced 50,900 subscribers at the date of acquisition of each of
its systems, to approximately 222,200 lines and subscribers upon completion of
the build-out of the Expansion Plan by December 31, 1998. The Expansion Plan
also involves the upgrade of each of its telephone networks to state-of-the-art
digital and fiber-optic technology.
 
  The Company has entered into agreements and letters of intent with Siemens
for the purchase of most of the telephone equipment required for the Expansion
Plan and for the installation of the equipment to be provided to the Company
pursuant to fixed price turn-key construction contracts. In addition, the
Company has entered into an agreement with IBM de Colombia S.A. (an affiliate
of International Business Machines Corp. ("IBM"))
 
                                       9
<PAGE>
 
for the purchase and installation of hardware and software that will be used to
offer value-added services for its telephone systems which, together with the
equipment provided by Siemens, comprises most of the equipment necessary to
complete the Expansion Plan. As of February 28, 1998, the Company, in
conjunction with Siemens, had completed the installation of approximately
105,100 new lines, or approximately 64% of the Company's Expansion Plan.
 
  The Expansion Plan is projected to require aggregate capital expenditures of
approximately $181.8 million, approximately 70.0% of which will be incurred
pursuant to fixed price equipment purchase agreements (or letters of intent)
and turn-key installation contracts. As of September 30, 1997, approximately
$7.8 million was financed with local bank borrowings, all of which was repaid
with a portion of the proceeds of the Offering, and approximately $1.5 million
was financed with cash flow from operations. The remainder of the Expansion
Plan, approximately $172.5 million, has been or will be financed with (i)
approximately $41.0 million of the proceeds of the Offering; (ii) approximately
$102.7 million provided by the Company's vendors under equipment financing
agreements (with Siemens and IBM) or domestic leasing arrangements
(collectively, the "Vendor Financing") (see "Risk Factors--Contingency of
Vendor Financing"); (iii) the sale of investments of $5.7 million; and (iv)
approximately $23.1 million provided by the Departamento de Impuestos y Aduanas
Nacionales (National Department of Taxes and Duties) ("DIAN") to finance the
taxes and duties payable on imported telecommunications equipment (the "DIAN
Financing", and together with the Offering, the Vendor Financing and the Equity
Contribution (as defined herein), the "Expansion Plan Financing"). See "Use of
Proceeds." As of February 28, 1998, the Company had incurred approximately
$118.2 million of capital expenditures relating to the Expansion Plan and
expects to incur the remainder, approximately $63.6 million, by the end of
1998.
 
  For the Company's expansion plan with respect to TeleGirardot, see
"Prospectus Summary--Recent Developments."
 
BUSINESS AND GROWTH STRATEGY
 
  The Company's objective is to become the leading provider of quality
telephone services in each city in which it operates. The Company's business
and growth strategy includes the following:
 
  . Capitalize on Significant Demand for Telephony Services. The Company
    believes that the low telephone penetration levels throughout Colombia,
    in general, and the southwestern region in particular, provide a
    substantial opportunity to quickly increase subscribers, net income and
    EBITDA in its markets. In the aggregate, the Expansion Plan assumes that
    the Company increases penetration of its markets from approximately 16.9
    lines per 100 people at the time of acquisition to 22.8 lines per 100
    people upon completion of the Expansion Plan. Management expects similar
    penetration increases with respect to the TeleGirardot Expansion Plan.
    Management believes that these penetration levels are achievable,
    especially when compared to two of Colombia's largest cities, Bogota and
    Medellin, where substantial capital has already been spent to expand and
    modernize the telephone systems and where penetration levels are
    currently in excess of 30 lines per 100 people. Furthermore, after
    operating in Palmira for only 28 months, the Company added more than
    34,400 subscribers, which represents an increase in telephone penetration
    from 4.9 lines per 100 people to approximately 18 lines per 100 people at
    December 31, 1997.
 
  . Create Strategic Alliances with Municipalities. The Company seeks to
    maintain a strong relationship with each of the municipalities in which
    it operates. This is accomplished primarily by establishing a mixed
    capital company in which both the Company and the municipality are
    investors. This structure allows the municipality to enjoy the benefits
    of privatization while maintaining an ongoing economic interest in these
    telephone operations. At the same time, the Company realizes substantial
    benefits from working together with the municipal government, including:
    (i) access to extensive demographic information which allows the Company
    to optimize its network build out; (ii) work permits and rights of way to
    ensure that the build out plan is completed quickly and efficiently; and
    (iii) access to public records regarding non-paying customers of the
    local government's other utility services. In addition, in
 
                                       10
<PAGE>
 
   situations where the Company has acquired existing telephone systems,
   management has the opportunity to retain the qualified employees of those
   systems.
 
  . Utilize International Expertise. Since its inception, the Company has
    contracted for the support of various internationally recognized
    consultants to complement its own expertise. Prior to entering a new
    market, management completes a full market demand study and in certain
    instances has relied on the services of independent research consultants
    to gather and assess projected levels of demand as well as other
    demographic and competitive information. The Company then sizes and
    designs its networks around these demand parameters. Commonwealth
    Communications, Inc. advised the Company with respect to the initial
    selection of equipment manufacturers and the design of the Palmira,
    Jamundi and Yumbo wireline telephone systems, and Bell Communications
    Research ("Bellcore") advised the Company with respect to the selection
    of equipment and design of the Unitel Wireless system in Cali. Pursuant
    to the Expansion Plan and the TeleGirardot Expansion Plan, the Company
    will rely on Siemens for the supply of equipment for both its wireline
    and wireless networks as well as the design, construction and
    installation of most of its systems pursuant to fixed price, turn-key
    contracts. In addition, the Company has contracted with IBM to install
    Internet-related services. The Company has also contracted C-NIX, a
    leading international information and operating systems provider, to
    upgrade its existing facilities and enhance the interface between its
    management control and information systems. Management believes that the
    Company has realized substantial benefits from these telecommunication
    services and expects to continue to utilize the expertise of these
    organizations.
 
  . Install Modern Telephony Equipment. The Company seeks to install high-
    capacity, modern telephony equipment with sufficient capacity to meet
    each market's expected demand. In the case of its wireline networks, the
    Company, in conjunction with its primary equipment vendor, Siemens, has
    installed a fiber-optic trunk supported by fully digital local exchanges.
    In the case of its wireless networks, the Company is installing a fixed
    wireless system utilizing DECT equipment provided by Siemens. This modern
    technology allows the Company to offer its subscribers a full range of
    traditional and non-traditional value-added services, including call
    waiting, voice mail, Internet access, ISDN and Centrex.
 
  . Maximize Revenue Generation. The Company seeks to maximize the revenue
    generated from each installed line by capitalizing on its efficient
    operating structure and by offering subscribers a full range of telephony
    services. One of the stated goals of the recent deregulation of the local
    telephone markets by the Colombian government is to promote competition
    among public and private operators on the basis of efficiency and
    customer service, rather than price. The government accomplished this by
    requiring operators to set tariffs, at their option, based on either (i)
    their or their predecessor's costs or (ii) their competitors' costs, but
    in no event below the cost of providing service. This law has benefited
    the Company by allowing management to set tariffs at levels established
    by inefficient municipal operators, rather than the Company's own lower
    cost of operation. This pricing structure allows the Company to realize a
    high return on its capital investment, especially when compared to its
    inefficient municipal competitors. The Company's operating results are
    further enhanced by the new, value-added telephony services that the
    Company offers as a result of its system upgrades which are not currently
    provided by its municipal competitors.
 
  . Provide Excellent Customer Service. Telephone subscribers in Colombia
    have historically received poor quality service. For example, under the
    management of the municipality, in September 1995, Palmira customers were
    able to complete approximately 40% of their calls and an estimated 17% of
    subscribers experienced breakdowns which lasted an average of more than
    12 hours. The Company utilizes sophisticated computer hardware and
    software to manage, administer and correct telephone problems in its
    telephone systems. This has resulted in a dramatic improvement in the
    operating performance of its systems. In Palmira, in February 1998, the
    Company's subscribers completed approximately 67% of their calls and only
    5.7% of subscribers experienced breakdowns lasting only approximately 6
    hours. In addition, the Company operates customer service centers in each
    of the Company's markets, and utilizes an aggregate of approximately 40
    dedicated employees for this purpose.
 
                                       11
<PAGE>
 
 
  . Pursue Selective Acquisitions and Other Business Opportunities. The
    Company intends to selectively pursue acquisitions of additional
    telephone networks from municipalities in Colombia engaged in
    privatizations. The Company anticipates making bids for one or more
    municipal systems in the upcoming months, including systems within and
    beyond the southwestern region of Colombia. Management expects that any
    future acquisitions will be structured similarly to its existing
    acquisitions, including a substantial investment and ownership by the
    municipality involved. The Company anticipates pursuing only those
    markets which have low penetration levels and indications of significant
    unmet demand for telephony service. In addition, the Company expects to
    capitalize on the recently initiated deregulation of the long distance

OWNERSHIP AND MANAGEMENT
 
  In August 1993, in anticipation of the deregulation of Colombia's
telecommunications industry, Guillermo Lopez combined his managerial expertise
with the financial support of certain members of the Caicedo family (the
"Caicedo Investors") to form the Company. The Caicedo family is a prominent
Colombian family with a history of operating businesses in the southwestern
region of Colombia dating back more than 400 years. Currently, the Caicedo
family has interests in sugar cane, milling and processing businesses in the
region, including Colombina S.A. ("Colombina"), Ingenio Riopaila S.A. and
Ingenio Central Castilla S.A. The existing shareholders of the Company have
invested approximately Ps37.4 billion ($30.0 million) in the Company, including
the sale of common stock of the Company to the existing shareholders for a
purchase price of Ps31.2 billion ($25.0 million), which was substantially
completed in July 1997 (the "Equity Contribution").
 
  Guillermo Lopez has been managing businesses for the Caicedo family for the
past 14 years. Prior to founding the Company, Mr. Lopez was the financial and
legal advisor to the Caicedo family with respect to their many business
interests and served as a member of the Board of Directors of several publicly
held companies in Colombia in which the Caicedo family had a substantial
interest. Since the Company's inception, Mr. Lopez has been actively involved
in all aspects of the business, including the acquisition of the Company's
telephone systems, the recruiting and hiring of the management team, and the
build-out and commencement of operations of the Company's systems.
 
  Mr. Lopez has assembled a senior management team comprised of individuals
with extensive telecommunications industry experience both in Colombia and
throughout the world. Reporting directly to Mr. Lopez is a General Manager for
each of the Operating Companies. Collectively, this group of nine executives
has over 120 years of telephony industry experience and includes Mr. Jose
Fernando Ramirez, the General Manager of TelePalmira, with 12 years of
experience with TELECOM and TELECOM affiliated companies, Mr. Danilo Ochoa, the
General Manager of Caucatel, with 16 years of experience with Empresas
Municipales de Cali ("EMCALI"), the municipally-owned telephone company
operating in Cali, Mr. Anibal Restrepo, the General Manager of Unitel, with 21
years of experience with Empresas Publicas de Medellin, the municipally-owned
telephone company operating in Medellin and Mr. Attilio Ciampini, the Manager
for the Company's Outside Plant, with 30 years of experience with Bell Canada,
a subsidiary of Bell Canada Enterprises. In addition to the General Managers,
Mr. Lopez's management team includes Mr. Anibal E. Perez, the Technology and
Planning Vice President, who has 15 years of experience with EMCALI, Mr. Jorge
Enrique Martinez, the Financial Vice President, who has nine years of
experience with Corporacion Financiera del Valle, Mr. Javier Salgado, the
Operations Vice President, who has 14 years of combined experience with Alcatel
de Colombia, S.A. ("Alcatel Colombia") and Alcatel de Venezuela, C.A. ("Alcatel

who has nine years of combined experience with Transejes S.A., an affiliate of

THE TRUST
 
 General
 
  The Trust is a statutory business trust, created under Delaware law pursuant
to the Original Trust Agreement and the filing of a certificate of trust with
the Delaware Secretary of State on October 20, 1997. The Trust is governed by
the Trust Agreement. Wilmington Trust Company is the Pass Through Trustee for
the Trust. Marine Midland Bank will act as the paying agent, registrar,
Indenture Trustee (as defined herein) and Exchange Agent (as defined herein).
All action taken by the Trust will be conducted by the Pass Through Trustee.
The Trust exists for the exclusive purposes of (i) issuing and selling the
Certificates, (ii) using the proceeds from the sale of the Original
Certificates to acquire the Senior Notes, (iii) registering the Exchange
Securities under the Securities Act, (iv) exchanging the Original Securities
for the Exchange Securities and (v) engaging in only those other activities
necessary or incidental thereto (such as soliciting directions from the
Certificateholders and taking such actions as the Certificateholders owning a
majority of the principal amount of the Certificates direct). Accordingly, the
Senior Notes will be the sole assets of the Trust, and payments received in
respect of the Senior Notes will be the sole source of revenue of the Trust.

Certain U.S. Federal Income
 Tax Considerations.........  The exchange of the Original Certificates for the
                              Exchange Certificates will not be a taxable event

                              purposes and, thus, the holder should not
                              recognize any taxable gain or loss as a result of
                              such exchange. See "Taxation--United States."

                              Holders" and therefore the holder should not
                              recognize any taxable gain or loss as a result of
                              such exchange. See "Taxation--Colombia."

 Certificates...............  Upon consummation of the Exchange Offer, the      
                              Original Certificateholders, if any, will have no

                              Original Certificates are not accepted for        
                              exchange will continue to hold such Original      
                              Certificates and will be entitled to all the same 
                              rights and will be subject to all the same        
                              limitations applicable thereto under the Trust    
                              Agreement (except for certain rights to be        
                              registered under the Act which terminate as a     
                              result of this Exchange Offer). All untendered

                              provided therein. To the extent that Original     
                              Certificates are not tendered and accepted in the 
                              Exchange Offer, an Original Certificateholder's   
                              ability to sell untendered and tendered but       
                              unaccepted Original Certificates could be         
                              adversely affected.       

CONSEQUENCES OF EXCHANGING ORIGINAL CERTIFICATES PURSUANT TO THE EXCHANGE OFFER
 
  Based on certain interpretive letters issued by the staff of the Commission
to third parties in unrelated transactions, Original Certificateholders (other
than any holder who is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act) who exchange their Original Certificates for
Exchange Certificates pursuant to the Exchange Offer generally may offer such
Exchange Certificates for resale, resell such Exchange Certificates, and
otherwise transfer such Exchange Certificates without compliance with the
registration and prospectus delivery provisions of the Securities Act provided
such Exchange Certificates 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
Exchange Certificates. Each broker-dealer that receives Exchange Certificates
for its own account in exchange for Original Certificates, where such Original
Certificates 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 Exchange Certificates. See
"Plan of Distribution." If an Original Certificateholder does not exchange such
Original Certificates for Exchange Certificates pursuant to the Exchange Offer,
such Original Certificates will continue to be subject to the restrictions on
transfer contained in the legend thereon. In general, the Original Certificates
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 Exchange Certificates".
 
  The Original Certificates 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
Original Certificates may continue to be traded in the PORTAL market. However,
to the extent that Original Certificates are tendered and accepted in
connection with the Exchange Offer, any trading market for remaining Original
Certificates will be adversely affected. Following consummation of the Exchange
Offer, the Exchange Certificates will not be eligible for PORTAL trading.

                              Indebtedness.
 
Optional Redemption.........  The Senior Notes are redeemable, in whole or in
                              part, at the option of the Company on or after
                              November 1, 2002 at the redemption prices set
                              forth herein plus accrued and unpaid interest to
                              the date of redemption.
 
Redemption Upon Sale of
 Capital Stock..............  At any time or from time to time on or prior to
                              November 1, 2000, in the event of the sale by the
                              Company of at least $25.0 million of its Capital
                              Stock in one or more Public Equity Offerings or
                              to one or more Strategic Equity Investors (as
                              defined herein), the Company may, at its option,
                              use the net cash proceeds of such sale or sales
                              to redeem up to 35% of the Senior Notes at a
                              redemption price

                              specified herein of the principal amount thereof
                              plus accrued and unpaid interest to the date of
                              redemption; provided, that at least 65% of the
                              initial aggregate amount of the Senior Notes
                              originally issued remains outstanding after any
                              such redemption.
 
Security....................  The Company has loaned approximately $98.3
                              million of the proceeds of the Senior Notes to
                              its Operating Companies. These loans are
                              evidenced by intercompany notes (the
                              "Intercompany Notes").
 
Ranking.....................  The Senior Notes are senior obligations of the
                              Company ranking pari passu in right of payment
                              with all existing and future senior Indebtedness
                              (as defined herein) of the Company and ranking
                              senior in right of payment to all existing and
                              future subordinated Indebtedness of the Company.
                              The Intercompany Notes are senior unsecured
                              obligations of each of the Operating Companies.
                              The Senior Notes are secured by a pledge of the
                              Intercompany Notes and by a pledge of the Escrow
                              Account. The Company is a holding company that
                              conducts substantially all its operations through
                              the Operating Companies. Therefore, other than
                              claims under the Intercompany Notes, the Senior
                              Notes are effectively subordinated to all debt
                              and other liabilities of the Operating Companies.
                              As of September 30, 1997, on a pro forma basis,
                              after giving effect to the Offering and the
                              Equity Contribution and the application of the
                              net proceeds therefrom, the Company and its
                              subsidiaries on a consolidated basis would have
                              had approximately Ps188.3 billion ($151.1
                              million) of debt outstanding, excluding any
                              amounts arising under the Vendor Financing and
                              the DIAN Financing. In addition, as of September
                              30, 1997, on a pro forma basis, the Operating
                              Companies would have had Ps7.9 billion ($6.4
                              million) of other liabilities. For the purpose of
                              the Indenture, the Vendor Financing and the DIAN
                              Financing, without duplication, will be
                              considered Indebtedness as they arise and
                              therefore, as of September 30, 1997, on a pro
                              forma basis, the Company and its subsidiaries had
                              Indebtedness of Ps191.1 billion ($153.3 million).
 
Change of Control...........  Upon a Change of Control, the Company will be
                              required to make an offer to repurchase the
                              Senior Notes at a price equal to 101% of the
                              principal amount thereof, plus accrued and unpaid
                              interest, to the date of repurchase. See "Risk
                              Factors--Inability to Redeem Senior Notes within
                              One Year."
 
Certain Covenants...........  The Indenture imposes certain limitations on the
                              ability of the Company and its subsidiaries to,
                              among other things, incur additional
                              indebtedness, incur liens, pay dividends or make
                              certain other restricted payments, consummate
                              certain asset sales, enter into certain
                              transactions with affiliates, issue preferred
                              stock, merge or consolidate with any other person
                              or sell, assign, transfer, lease, convey, or
                              otherwise dispose of all or substantially all of
                              the assets of the Company and its subsidiaries.
                              Pursuant to the Indenture, the Company may not
                              loan more than 20% of the proceeds from the
                              issuance of the Senior Notes to any one Operating
                              Company.

SUMMARY FINANCIAL AND OTHER DATA
 
  The Company was incorporated in 1993 and commenced offering telephone
services in September 1995. Accordingly, the Company has no commercial
operating history prior to such time, and results for 1995 are not directly
comparable to those of 1996. The Company was in a preoperating stage prior to
September 1, 1995 and capitalized all of its net expenses as deferred charges;
thus, no statements of income are presented for 1993 and 1994. The summary
statement of income data for each of the years ended December 31, 1995 and 1996
and the nine months ended September 30, 1997, and the summary balance sheet
data as of December 31, 1994, 1995 and 1996 and September 30, 1997 have been
derived from audited financial statements. The summary balance sheet data at
December 31, 1993 have been derived from unaudited consolidated financial
statements of the Company. 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 Consolidated
Financial Statements, including the notes thereto, included elsewhere in this
Prospectus.
 
  The Consolidated Financial Statements included herein have been prepared in
conformity with Colombian GAAP (including restatement of the financial
information in constant pesos as of September 30, 1997), which differs in
certain significant aspects from generally accepted accounting principles in
the United States ("U.S. GAAP"). Note 28 to the Consolidated Financial
Statements provides a discussion of the principal differences between Colombian
and U.S. GAAP as they relate to the Company and a reconciliation of net income
and shareholders' equity for the Company as of and for the years ended December
31, 1995 and 1996 and as of and for the nine months ended September 30, 1997 to
amounts calculated in accordance with U.S. GAAP.
 
  Dollar equivalent information set forth below has been included solely for
the convenience of the reader, and is translated from Pesos at the
Representative Market Rate in effect on September 30, 1997 of Ps1,246.27 to one
Dollar. Such translation should not be construed as a representation that the
Peso amounts represent, or have been or could be converted into, Dollars at
that rate or any other rate.
 
  Unless otherwise indicated, all financial information included in this
Prospectus has, for comparability purposes, been restated in constant Pesos as
of September 30, 1997 by indexing historical amounts using the MCPI. Although
the restatement of nominal Pesos into constant Pesos lessens the distorting
effect that an inflationary environment has on comparisons of Consolidated
Financial Statements over time, such restatement does not wholly eliminate
those distortions and evaluation of period-to-period trends may be difficult.
See "Risk Factors--Corporate Disclosure and Accounting Standards" and "Risk
Factors--Inflation."

(1) For Colombian GAAP purposes, as of January 1, 1996, TelePalmira changed
    from the straight-line to the reverse sum of the years digits' method of
    computing depreciation which had the effect of decreasing 1996 depreciation
    (and increasing 1996 income before income taxes and minority interest) by
    Ps914,548 ($734) and increasing 1996 net income by Ps548,728 ($440). For
    U.S. GAAP purposes, all periods use the straight-line method.
(2) EBITDA is defined as operating income (loss) plus depreciation and
    amortization and plus lease expense related to the Vendor Financing under
    Colombian GAAP. Under U.S. GAAP, the Vendor Financing is treated as debt
    and therefore the associated cost is treated as interest expense and
    principal payment rather than lease expense. Although EBITDA is not a
    measure of performance calculated in accordance with Colombian or U.S.
    GAAP, the Company has included such data because it is used by certain
    investors to determine the Company's ability to meet debt service
    requirements. Such data should not be considered as an alternative to net
    earnings as an indicator of the Company's operating performance or as an
    alternative to cash flows from operating activities as a measure of
    liquidity.
(3) Capital expenditures consist of purchases of properties, plant and
    equipment as reflected in the Company's consolidated statements of cash
    flows.
(4) Total Indebtedness is calculated in accordance with the definition of
    "Indebtedness" under the Indenture, which includes short-term debt, long-
    term debt, capital lease obligations, lease payments under the Vendor
    Financing (which are treated as operating leases under Colombian GAAP, but
    are capitalized under U.S. GAAP), and the Company's obligations under the
    DIAN Financing.
(5) For purposes of computing the deficiency of earnings to fixed charges,
    "earnings" consist of income (loss) before income taxes, minority interests
    and fixed charges, excluding capitalized interest. Fixed charges consist of
    interest on all indebtedness (whether capitalized or expensed) and that
    portion of operating lease expenses deemed to be interest expense.
(6) Penetration represents the number of installed lines per 100 people. In
    Cartago, Jamundi and Yumbo, penetration includes the installed lines of
    municipal competitors as of December 31, 1996 of approximately 10,000
    lines, 5,200 lines and 5,500 lines as per the Company's estimates,
    respectively.
(7) Short-term debt includes current portion of long-term debt, current portion
    of capital lease obligations and short-term debt.
(8) Long-term debt includes long-term debt and capital lease obligations.

RECENT DEVELOPMENTS
 
 Empresa de Comunicaciones de Girardot S.A. E.S.P.
 
  On December 31, 1997, TeleGirardot, a new subsidiary, was formed by the
Company. TeleGirardot was capitalized with Ps8.9 billion ($7.1 million) in cash
contributed by the Company to TeleGirardot in exchange for a 60% interest in
TeleGirardot. The municipality of Girardot contributed the net assets of its
telephone network (which had approximately 23,500 subscribers) with a fair
market value of Ps5.9 billion ($4.8 million) to TeleGirardot in exchange for a
40% interest in TeleGirardot. The municipality's telephone network commenced
operations on December 2, 1978.
 
  TeleGirardot serves the cities of Girardot, Flandes and Ricaurte. Girardot
and Ricaurte are located 362 kilometers east of Cali and 127 kilometers
southwest of Bogota. Flandes is located 363 kilometers east of Cali and 128
kilometers southwest of Bogota. The economic base of the three cities is
tourism, agriculture and cattle raising. The aggregate population of the three
cities is approximately 161,000 people.
 
  Upon the commencement of Transtel's operation of TeleGirardot on December 31,
1997, TeleGirardot's subscriber base was composed of approximately 80%
residential and 20% commercial subscribers. TeleGirardot's competitor in its
service area is TeleTequendama E.S.P., which currently has approximately 8,500
subscribers.
 
  On December 31, 1997, TeleGirardot had 24,500 subscribers in Girardot.
Transtel expects, through its expansion plan (the "TeleGirardot Expansion
Plan"), to increase the number of installed lines in Girardot to 40,000 lines
by the end of 1998. Transtel expects to incur approximately $4.0 million under
the TeleGirardot Expansion Plan which will be financed with cash flow from its
operations. The Company is currently negotiating with Siemens to enter into
contracts for the supply of equipment to effect the TeleGirardot Expansion
Plan. As of February 28, 1998, TeleGirardot had approximately 1,000 new
subscribers, all of whom are serviced by digital lines, and approximately 70
employees.

                                 RISK FACTORS
 
  Original Certificateholders should consider carefully the following risk
factors as well as the other information contained in this Prospectus in
evaluating an investment in the Exchange Certificates, although the risk
factors set forth below are generally applicable to the Original Certificates
as well as the Exchange Certificates.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  Original Certificateholders who do not exchange their Original Certificates
for Exchange Certificates pursuant to the Exchange Offer will continue to be
subject to the restrictions on transfer of such Original Certificates as a
consequence of the issuance of the Original Certificates 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 Original Certificates 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 Exchange Certificates."
 
SUBSTANTIAL LEVERAGE OF THE COMPANY; INSUFFICIENCY OF EARNINGS TO COVER FIXED
CHARGES
 
  The Company is highly leveraged. Even though a portion of the proceeds of
the Offering was used to repay debt, after the Offering, the Company and its
subsidiaries had as of September 30, 1997 on a pro forma basis approximately
Ps191.1 billion ($153.3 million) of Indebtedness, which includes the Vendor
Financing and the DIAN Financing. The Indenture limits, but does not prohibit,
the incurrence of additional Indebtedness, secured or unsecured, by the
Company and its subsidiaries. Although funds sufficient to pay the first four
interest payments on the Senior Notes (and therefore on the Certificates) were
placed into the Escrow Account, future interest payments on the Senior Notes
(and therefore on the Certificates) will be payable from the Company's cash
flow. The debt service requirements of any additional debt could make it more
difficult for the Company to make principal and interest payments on the
Senior Notes and consequently, the Trust's ability to make payments on the
Certificates. For the years ended December 31, 1995 and 1996 and for the nine
months ended September 30, 1997, earnings were insufficient to cover fixed
charges by Ps11.4 million ($9,100), Ps114.2 million ($91,700) and Ps1.6
billion ($1.3 million), respectively.
 
  There can be no assurance that the Company will be able to generate
sufficient cash flow to cover either the required interest and principal
payments or any required redemptions or repurchases of the Senior Notes and
consequently, the Trust's ability to make payments on the Certificates. If the
Company is unable to meet interest and principal payments or any required
redemptions or repurchases of the Senior Notes in the future, it may,
depending upon the circumstances which then exist, seek additional equity or
debt financing, attempt to refinance its existing indebtedness or sell all or
part of its business or assets to raise funds to repay its indebtedness. There
can be no assurance that the Company will be able to generate sufficient cash
flow to cover any required payment on the Senior Notes and consequently the
Trust would not have the ability to make the corresponding payment on the
Certificates. There can be no assurance that sufficient equity or debt
financing will be available, or, if available, that it will be on terms
acceptable to the Company, that the Company will be able to refinance its
existing indebtedness or that sufficient funds could be raised through asset
sales.
 
  The high degree of leverage of the Company may have important consequences
to Certificateholders. In particular: (i) a substantial portion of the
Company's anticipated cash flow from operations will be required for the
payment of the Company's interest expense and principal repayment obligations
on the Senior Notes; (ii) the ability of the Company to obtain additional
financing in the future for working capital, acquisitions, capital
expenditures, repayment of debt, or other purposes is limited by restrictive
covenants in the Indenture; and (iii) the Company may be more vulnerable to
downturns in general economic conditions or in its business and may have less
flexibility to respond to changing business conditions and opportunities.
 
                                      22

COLOMBIAN POLITICAL, ECONOMIC AND SOCIAL RISKS
 
  The Company is located in Colombia and is subject to political, economic and
other uncertainties, including expropriation, nationalization, renegotiation,
or nullification of existing contracts, currency exchange restrictions and
international monetary fluctuations. Furthermore, Colombia has experienced
violence related to guerrilla activity. The Indenture will not require the
Company, and the Company does not intend, to maintain insurance against such
risks.
 
  Cali and its metropolitan area, the Company's largest market, has been the
center of operations of one of Colombia's most powerful drug organizations,
and as such has suffered the violence resulting from the Colombian
government's efforts to curb the drug trade. Cali may also have received
portions of the capital generated by the drug trade, to the extent some of
such capital was reinvested locally. The Company believes that neither the
drug trade nor the efforts to curb it have had a material adverse effect on
its business. However, no assurance can be given that drug activity in the
future will not have a material adverse effect on the Company or that the
efforts to curb such activity will not have a material adverse effect on the
economy of the region and thereby on the Company.
 
  Since March 1, 1996, the United States government has declined to recertify
Colombia as qualifying for United States foreign aid, due to a perceived
failure by Colombia to cooperate adequately in combating the drug trade.
However, on February 26, 1998, due to the recent operations performed by the
Colombian Army and the National Police Department against the Colombian drug
cartels, the United States government certified Colombia with a "waiver".
Although the certification with a waiver does not mean that Colombia is
qualified for United States foreign aid, it does mean that Colombia is not
subject to economic or trade sanctions. The certification with a waiver
implies that the United States is able to vote in favor of Colombia at the
boards of multilateral agencies and credit institutions, such as the World
Bank, the Overseas Private Investment Corporation, OPIC, Export-Import Bank,
Eximbank and the Interamerican Development Bank, IDB.
 
  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
on the Company. Certificateholders should recognize that these conditions and
events create significant uncertainties and risks, which could result in
material adverse effects on the Company and on its ability to meet its
obligations, including its obligations under the Senior Notes and
consequently, the Trust's ability to pay on the Certificates.
 
  In addition to these political and social uncertainties, investment in
Colombia, as with all emerging markets, is subject to economic uncertainties.
Colombia is divided into thirty-two political subdivisions called
departamentos (departments). The Company's operations are dependent upon the
performance of the Colombian economy generally, and, in particular, upon the
performance of the economies of the Departamentos of Valle del Cauca and
Cauca. The economies of Colombia and these departamentos are 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 affected by such
fluctuations in the economies of Colombia, of Valle del Cauca, of Cauca, and
of any other departamentos in which the Company operates in the future, and
such fluctuations may affect the ability of customers to pay for the Company's
services and on the ability of the market to support the growth of 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 Senior Notes and consequently, the Certificates. There can be no
assurance that recent policies that have resulted in favorable economic growth
will be maintained by this government or any new government or that such
growth will continue.
 
 
                                      23
<PAGE>
 
HOLDING COMPANY STRUCTURE; LIMITATIONS ON ACCESS TO CASH FLOW OF OPERATING
COMPANIES; EFFECTIVE SUBORDINATION
 
  The Senior Notes will be the exclusive obligation of the Company, which is a
holding company with no business operations of its own. The operations of the
Company are conducted through the Operating Companies, which are separate and
distinct legal entities. Other than the obligation to repay to the Company the
Intercompany Notes, the Operating Companies have no obligation, contingent or
otherwise, to pay any amounts due pursuant to the Senior Notes or the
Certificates, to make any funds available to the Company to enable it to make
payments on the Senior Notes and consequently, to make the funds available to
the Trust to make payments on the Certificates, to make funds available in
order to make investments in the Operating Companies, to meet working capital
needs or other liabilities of the Company or for any other reason. In
addition, the Operating Companies are not wholly-owned subsidiaries of the
Company and any dividends issued by the Operating Companies must be
distributed pro rata to all of their shareholders. As a result, the Company
cannot be assured that it will be able to generate significant cash through
dividends or other distributions from the Operating Companies in the
foreseeable future and there can be no assurance that the Company will be able
to generate any significant cash flow from the Operating Companies at any time
in the future. Since the Company's assets consist primarily of its ownership
interests in the Operating Companies, the Senior Notes (and therefore the
Certificates) will be effectively subordinated (other than as to claims that
the Company can make under the Intercompany Notes) to all existing and future
debt and other liabilities (including trade payables) of the Company's
Operating Companies, and the Company's right to receive the assets of the
Operating Companies upon their liquidation or reorganization will be subject
to the claims of such Operating Companies' creditors (including trade
creditors).
 
LIMITED OPERATING HISTORY; POTENTIAL LACK OF CUSTOMER DEMAND
 
  The Company is a new enterprise. It was incorporated in August 1993 and
commenced offering telephone services through TelePalmira on September 1,
1995. Most of the Company's systems have only recently begun to be operated by
Transtel. Unitel Wireless commenced operations on January 2, 1998.
TeleCartargo, Caucatel, TeleJamundi, Unitel Wireline and Bugatel commenced
operations on April 1, 1997; May 1, 1997; June 1, 1997; June 1, 1997; and July
1, 1997, respectively. TeleGirardot commenced operations on December 31, 1997.
The successful development and commercialization of these systems will depend
on a number of significant financial, logistical, technical, marketing, legal
and other factors, the outcome of which cannot be predicted. These Operating
Companies will require additional funds for capital expenditures, working
capital requirements, and other cash needs, including the costs of obtaining
additional equipment. In addition, there can be no assurance that the systems
will not encounter engineering, design, or other operational problems. There
can be no assurance that the Company can successfully develop any future
systems or that any of its systems will achieve commercial success.
 
  Additionally, the extent to which prospective telephone customers will
choose to obtain telephone service from the Company is unclear. The Company
has incurred and will continue to incur significant operating expenses, has
made, and will continue to make, significant capital investments, has entered
into operating leases, equipment supply contracts and service arrangements, in
each case based upon certain expectations as to the anticipated market
acceptance of, and customer demand for, the Company's telephony services. The
failure to meet these expectations could have a material adverse effect on the
Company. A substantial portion of the Company's revenues to date have been
derived from non-recurring connection charges. The continuation of this
revenue stream will depend on the Company continuing to obtain new
subscribers, which cannot be assured.
 
RISKS ASSOCIATED WITH PRIVATIZATION AND MANAGEMENT OF GROWTH
 
  The success of the Company's operating strategy is subject to factors that
are beyond the control of the Company and are impossible to predict, in part,
because the telecommunications industry has only recently begun to be
privatized in Colombia. The Company is unable to predict how consumer demand
for telecommunications services will develop over time. The size of the
Colombian market for telecommunications services, the rates of
 
                                      24
<PAGE>
 
penetration of the market and the sensitivity of potential subscribers to
changes in prices, among other factors, are uncertain. Moreover, the provision
of telephony service with additional calling features is without precedent in
Colombia and, therefore, the market acceptance and customer demand for such
services is uncertain. In addition, the Company's continued rapid growth will
require the training of new personnel, the expansion of its management
information systems, 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 Senior Notes and consequently, the Trust's ability to pay on the
Certificates may suffer a material adverse effect.
 
NETWORK ROLLOUT RISKS; RELIANCE ON SUPPLIERS; DELAYS IN CONSTRUCTION
 
  The Company's service is dependent upon the completion and continued
viability of its network. The Company has completed portions of its network
and expects to incur significant expenditures to expand the geographic
coverage and increase the capacity of its network. The roll-out of the
Company's network is subject to risks and uncertainties that could delay the
rollout of the Company's services and increase the cost of construction.
 
  With respect to wireless networks, one such risk is the availability, access
to, and continued use of, suitable base stations and switch sites. The
Company's ability to locate and retain suitable base stations and switch sites
is dependent on the cooperation of local planning authorities and potential
landlords. There can be no assurance that the Company will be successful in
obtaining property rights necessary to establish or maintain such base
stations and switch sites, or that delays in obtaining such rights will not
adversely affect the rate of the Company's network rollout.
 
  The currently planned build out and upgrade of the Company's networks is
reliant on Siemens for the supply of equipment and other telecommunications
supplies and for construction of the networks. There can be no assurance that
Siemens will honor its current obligations to supply equipment and construct
the networks or that it will desire or be able to supply such equipment or
undertake construction of future projects. Equipment supplies are additionally
subject to shortages and/or delays in delivery. In addition, with respect to
letters of intent to enter into purchase agreements with respect to equipment,
there can be no assurance that the letters of intent are binding on Siemens or
that definitive purchase agreements will be entered into. Accordingly, there
can be no assurance that currently planned projects or future projects will be
completed within the time periods projected, or at all. Failure to obtain
equipment on a timely basis, or at all, could jeopardize subscriber contracts
and could have a material adverse effect on the Company.
 
  The construction of the Company's networks in the municipalities of Palmira,
Jamundi, Yumbo, Cartago and Buga are currently governed by turn-key contracts
which obligate Siemens and the other contractors to finish construction or
installation. See "Business--Construction Arrangements." However, any future
projects will typically require substantial construction of new networks or
upgrades to existing networks, and no such construction obligation has been
undertaken by a third party. Construction activity will require qualified
subcontractors and necessary equipment to be secured on a timely basis, the
availability of which may vary significantly from location to location.
Construction projects may experience cost overruns and delays outside the
control of the Company or its subcontractors, such as those caused by acts of
governmental entities, financing delays and catastrophic occurrences. Delays
also can arise from design changes and material or equipment shortages or
delays in delivery. Accordingly, there can be no assurance that such projects
will be completed within the amount budgeted therefor or on time, or at all.
Failure to complete construction within the amount budgeted or on time could
jeopardize subscriber contracts and could have a material adverse effect on
the Company.
 
  If the Company were to decide to pursue other investments or make other
expenditures, other than the Expansion Plan, additional capital resources
would be required. If the Company is unable to fund such
 
                                      25
<PAGE>
 
expenditures or investments, or if the Company's cash flow from operations
does not increase from its present level, the Company might not be able to
continue to pursue its network construction and subscriber growth strategy.
 
POTENTIAL NEED FOR ADDITIONAL EQUIPMENT
 
  The success of the Company's telecommunications system is partially
dependent on the completion of its Expansion Plan and its TeleGirardot
Expansion Plan. See "Business--Expansion Plan." Although the Company has
entered into equipment purchase agreements with Siemens and IBM, there can be
no assurance that future network evaluations or other similar factors will not
necessitate the Company's re-evaluation of its equipment needs. See
"Description of Existing Indebtedness--Global-Siemens Arrangements,"
"Description of Existing Indebtedness--Transtel-Siemens Arrangement",
"Description of Existing Indebtedness--IBM Arrangement" and "Prospectus
Summary--Recent Developments." If equipment requirements do increase,
additional capital or financing sources would be required. There can be no
assurance that the Company will be able to fund such capital expenditures or
obtain such financing on terms favorable to the Company.
 
CONTINGENCY OF VENDOR FINANCING
 
  The build out and upgrade of the Company's networks and the completion of
the Expansion Plan is reliant on equipment vendor financing from Siemens and
IBM. While there are two purchase agreements with Siemens, a purchase
agreement with IBM, and two letters of intent with Siemens that the Company
expects will result in one or more purchase agreements for the provision of
equipment required for the Expansion Plan, the Company is negotiating (i) the
financing terms and agreements with Siemens and IBM with respect to some of
the equipment and (ii) an amendment to a Siemens purchase agreement to
increase the amount of financing under such purchase agreement. See
"Description of Existing Indebtedness--Global-Siemens Arrangements" and
"Description of Existing Indebtedness--IBM Arrangements." Additionally, the
Company is currently negotiating with Siemens to enter into contracts for the
supply of equipment to effect the TeleGirardot Expansion Plan. There can be no
assurance that the financing from Siemens or IBM will be available and if it
is not available, whether other financing will be available to the Company. In
addition, there can be no assurance that financing agreements will be entered
into and if entered into, whether the terms of such financing agreements will
be favorable to the Company.
 
RISKS ASSOCIATED WITH COLOMBIAN PLEDGE AND ENFORCEMENT OF FOREIGN JUDGMENTS
 
  The Senior Notes are secured by a pledge of the Intercompany Notes. The
pledge is a security instrument governed primarily by the Codigo de Comercio
(Commercial Code) and the Codigo de Procedimiento Civil (Code of Civil
Procedure) and there can be no assurance that this arrangement will be
effective to create a senior perfected security interest in the Intercompany
Notes enforceable in the same manner and to the same extent as a security
interest granted under the laws of the United States. An action to enforce the
pledge can only be executed before a Colombian court. The process employed in
executing the pledge entails a court order to sell the pledged asset to the
public, either by public auction or through a local stock exchange, with the
proceeds of the sale going to pay the defaulted obligations. The right to
initiate the judicial proceedings to enforce a pledge expires four years after
the obligation becomes enforceable. Historically, the enforcement of pledges
before Colombian courts has been a long process. The delays of a trial to
enforce the pledge may have a material adverse effect on the Colombian court's
ability to obtain payment of the full value for the Senior Notes and
therefore, on the Trust's ability to repay the Certificates.
 
  In addition, substantially all of the assets of the Company will be located
in Colombia. As a result, it may not be possible for the Pass Through Trustee,
the Indenture Trustee or the Exchange Certificateholders to enforce outside of
Colombia judgments against the Company, including enforcement in the United
States of judgments predicated upon the civil liability provisions of the
United States federal securities laws or a judgment to enforce the Certificate
Guarantees. The United States and Colombia do not have a treaty providing for
reciprocal recognition and enforcement of judgments in civil and commercial
matters. See "Enforcement of Foreign
 
                                      26
<PAGE>
 
Judgments in Colombia." For a foreign judgment to be effective and enforceable
in Colombia, it must be proved in accordance with the Rules of Court in
Colombia, as contained in the Colombian Code of Civil Procedure, pursuant to
which a demand for an exequatur (proceedings in the Colombian Judicial System
for recognition of a foreign judicial decision or arbitral award) must be
presented before Colombia's Supreme Court of Justice. Therefore, a final
judgment for the payment of money rendered by a federal or state court in the
United States based on civil liability, whether or not predicated solely upon
the civil liability provisions of the United States federal securities laws,
would be enforceable in Colombia against the Company only if it has been
proven in accordance with the Colombian Rules of Court. The Company also has
been advised by its Colombian counsel 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.
 
COMPETITION
 
  There is currently no restriction in Colombia on competition within the
local telephony business. It is possible that competitors, including companies
with substantially greater capital or other resources than the Company, could
commence operations in the Company's service area and offer wireline,
wireless, cellular, Personal Communication Services ("PCS") or other
competitive telecommunications services. The Company currently faces
competition in certain cities primarily from various state-run providers of
local telephony service. Competition is based on services offered, quality of
service and coverage area. See "Industry Overview; Legal and Regulatory
Environment" and "Business--Operating Companies--General."
 
TECHNOLOGICAL RISK; RISK OF OBSOLESCENCE
 
  The Company's Operating Companies generally use advanced technologies.
Although many of the technologies currently in use and to be used in the
future by the Company have been developed by international telecommunications
companies, such as Siemens, some have only recently been developed and
commercially introduced. There can be no assurance that the Operating
Companies will not experience technical problems in the commercial deployment
of these technologies, particularly because they are being introduced in a
developing country. In addition, the technology used in wireless
communications is evolving rapidly and one or more of the technologies
currently utilized or planned by the Company may not be preferred by its
customers or may become obsolete, which in either case would likely have a
material adverse effect on the Company. There can be no assurance that the
Company will be able to keep pace with ongoing technological changes in the
telecommunications industry.
 
REGULATORY RISKS
 
  The privatization of telecommunications services in Colombia is dependent
upon Law 142. There can be no assurance that material adverse changes to Law
142 will not occur in the future. Additionally, certain Operating Companies
could become subject to service requirements, restrictions on interconnection
to government-owned or private telephone networks and government requirements
regarding rates and tariffs, among others. These requirements may be difficult
to comply with, particularly given demographic, geographic, or other issues in
a particular market. Further, changes in the regulatory framework may limit
the Operating Companies' ability to add subscribers to developing systems. An
Operating Company's failure to comply with applicable governmental regulations
or operating requirements could have a material adverse effect on the Company.
Further, the Company's current and anticipated ownership interests in the
Operating Companies are subject to continued support by the Colombian
government of privatization of the telecommunications sector.
 
  Additionally, the pricing of the Company's services and related matters are
subject to regulation by the CRT. Changes in the regulation of the Company's
pricing, or a change in the interpretation of the existing regulations, could
have a material adverse effect on the Company. See "Industry Overview; Legal
and Regulatory Environment."
 
                                      27
<PAGE>
 
  Furthermore, the frequency assigned to the Company with respect to Unitel's
fixed wireless system, which was assigned by the Ministerio de Comunicaciones
(Ministry of Communications), could be revoked if the Company operates out of
its assigned frequency, offers services other than those approved by the
Ministry of Communications or fails to comply with other regulations governing
such license.
 
RISK OF MODIFICATION OR LOSS OF PERMITS; UNCERTAINTY AS TO AVAILABILITY
 
  Each of the Operating Companies' ability to exploit its respective existing
civil works permits is essential to the Company's construction of its network.
These permits are granted by the municipalities in the areas served. Although
the municipalities are required to grant such permits under Law 142, there can
be no assurance that these permits will not become difficult to obtain, that
the law will always require their issuance, or that some prohibited action of
any of the Operating Companies will not cause their termination, and the
occurrence of any of these events could have a material adverse effect on the
Company. The Operating Companies may have limited legal recourse if any of
these events were to occur.
 
DEPENDENCE ON OTHER TELECOMMUNICATIONS PROVIDERS
 
  The success of the Company's telecommunication system will in many cases
depend upon access to the systems of other local telecommunications providers,
some of which may be competitors of the Company. Although access to such
service is required by Law 142, the revocation, loss, or modification of any
of the existing arrangements or the failure to obtain necessary agreements
and/or arrangements in the future could have a material adverse effect on the
Company. The Operating Companies are additionally required by Colombian law to
enter into interconnection arrangements with TELECOM. Although TELECOM is
currently providing such service and is required to continue to do so under
Colombian law, formal agreements are not in place with the Company's Operating
Companies, as is also the case with other telecommunications providers.
 
  There can be no assurance that such arrangements will continue to be
regulated by the Colombian government. Additionally, a breach by any of the
Operating Companies of these interconnection agreements could lead to loss of
such agreements, which could have a material adverse effect on the Company.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company is currently managed by a small number of key management and
operating personnel whose efforts will largely determine the Company's
success. The success of the Company also depends upon its ability to hire and
retain qualified operating, marketing, financial, accounting and technical
personnel. Competition for qualified personnel in the telecommunications
industry is intense and, accordingly, there can be no assurance that the
Company will be able to hire or retain necessary personnel. The loss of key
management personnel would likely have a material adverse effect on the
Company. See "Management."
 
CORPORATE DISCLOSURE AND ACCOUNTING STANDARDS
 
  A principal objective of the securities laws of the United States, Colombia
and other countries is to promote disclosure of all material corporate
information. However, it is likely that there would be less or different
publicly available information about the Company in Colombia than would be
available about issuers listed on stock exchanges in the United States or
certain other countries. In addition, the Company prepares its financial
statements in accordance with Colombian GAAP, which differs in significant
respects from U.S. GAAP. Thus, Colombian financial statements and reported
earnings may differ from those of companies in other countries in this and
other respects. For a description of the principal differences between
Colombian GAAP and U.S. GAAP, insofar as they are relevant to the Company, see
Note 28 to the Consolidated Financial Statements.
 
CURRENCY FLUCTUATIONS, FOREIGN EXCHANGE CONTROLS, AND DEVALUATION
 
  Since the consummation of the Offering, a substantial amount of the
Company's debt obligations, including the Senior Notes, are denominated in
Dollars while the Company generates revenues in Pesos. In addition, the
 
                                      28
<PAGE>
 
Company has incurred and expects to continue to incur a significant portion of
its equipment costs in Dollars. Therefore, the Company is exposed to currency
exchange rate risks that could significantly affect 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 Pesos to the Dollar is a freely
floating rate which has declined in recent years. Since the period from August
1, 1997 through December 31, 1997, the Peso devalued relative to the dollar
approximately 16.6%. Any significant 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 Senior Notes and
consequently, on the Trust's obligations under the Certificates. See "Exchange
Rates."
 
  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
remittance of interest and principal 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 Senior Notes.
As of July 4, 1997, the Central Bank's currency reserves were sufficient for
approximately 10 months of imports. Nevertheless, there is no assurance that
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 Senior Notes and
consequently, the Trust's obligations under the Certificates. There are no
limitations imposed by the Colombian government on nonresident or foreign
owners' ability to hold or vote the Senior Notes or the Certificates.
 
INABILITY TO REDEEM SENIOR NOTES WITHIN ONE YEAR
 
  Because of a recent modification in Colombian securities laws, it is not
clear whether the Senior Notes can be prepaid within one year of their
issuance, whether by redemption, repurchase, acceleration, or otherwise.
Moreover, there is no controlling legal precedent with respect to this issue.
The Company has been advised by its Colombian counsel that there is legal risk
in redeeming or repurchasing the Senior Notes within one year of their
issuance. Unless a positive precedent arises or a change of law occurs after
the issuance of the Senior Notes, the Company does not intend to prepay the
Senior Notes within one year of their issuance, whether by redemption,
repurchase, acceleration, or otherwise. The Company's inability to redeem the
Senior Notes when required under the Indenture would result in an Event of
Default under the Indenture.
 
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 19.5%, 21.6% and 17.4% in
1995, 1996 and 1997, 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 Certificates and Senior Notes will
not be adversely affected by continuing or increased levels of inflation.
 
LACK OF A MARKET FOR THE EXCHANGE CERTIFICATES; RISKS ASSOCIATED WITH NON-
INVESTMENT GRADE DEBT
 
  The Exchange Certificates are new securities for which there currently
exists no trading market. The Company does not intend to list the Exchange
Certificates on any national securities exchange or to seek admission thereof
to trading on the National Association of Securities Dealers Automated
Quotation System. The liquidity of any market for the Exchange Certificates
will depend on the number of Exchange Certificateholders, the interest of
securities dealers in making a market in the Exchange Certificates and other
factors. Accordingly, there can be no assurance as to the development or
liquidity of any trading market for the Exchange Certificates.
 
                                      29
<PAGE>
 
  To comply with the applicable state securities laws, the Exchange
Certificates may not be offered or sold by a Certificateholder unless they
have been registered or qualified for sale under such applicable state
securities laws or an exemption from registration or qualification is
available therefrom and is complied with.
 
  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 Exchange Certificates. There can be no assurance
that the market, if any, for the Exchange Certificates will not be subject to
similar disruptions. Any such disruptions may have an adverse effect on the
Exchange Certificateholders. 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 a material
adverse effect on the market value and liquidity of the Exchange Certificates.
 
CONTROL BY CERTAIN STOCKHOLDERS AND MANAGEMENT
 
  Certain of the Company's directors, executive officers and principal
stockholders beneficially own 100% of the outstanding common stock of the
Company. Accordingly, if they choose to act together, these persons will be
able to control the election of the Board of Directors and other matters voted
upon by the stockholders. A sale by one or more of these principal
stockholders to third parties could trigger the right of the
Certificateholders to require the Company to repurchase the Senior Notes. In
the event that an Offer to Purchase (as defined herein) occurs at a time when
the Company does not have sufficient available funds to purchase the Senior
Notes, or at a time when the Company is prohibited from purchasing the Senior
Notes, an Event of Default (as defined herein) could occur under the
Indenture.

  The deficiency of earnings to fixed charges for each of the periods set

(1) This deficiency of earnings to fixed charges is computed using the
    historical deficiency adjusted only for the additional interest costs and
    amortization of deferred debt issuance costs relating to the Senior Notes
    and the reduced interest costs relating to the debt refinanced. No
    adjustment has been made to reflect assumed interest income on any
    offering proceeds from the Senior Notes not utilized to refinance debt.
 
  For purposes of computing deficiency of earnings to fixed charges,
"earnings" consist of income (loss) before income taxes, minority interests
and fixed charges, excluding capitalized interest. Fixed charges consist of
interest on all indebtedness (whether capitalized or expensed), amortization
of deferred financing costs and that portion of operating lease expense deemed
to be interest expense.

                                USE OF PROCEEDS
 
  The Company will not receive any cash proceeds from the issuance of the
Exchange Certificates offered hereby. The Original Certificates surrendered in
exchange for the Exchange Certificates will be cancelled and can not be
reissued. The issuance of the Exchange Certificates will not result in any
change in the aggregate indebtedness of the Company.
 
  The net proceeds from the Offering were approximately $141.9 million
(Ps177.0 billion) after deducting discounts and offering expenses.
Approximately $35.3 million (Ps44.0 billion) was deposited into the Escrow
Account to satisfy the first four interest payments on the Senior Notes.
Approximately $32.8 million (Ps40.9 billion) was used to pay existing debt and
$9.8 million (Ps12.2 billion) was used to pay the Central Bank's withdrawal
fee. The balance of the proceeds has been or will be used to (i) fund a
portion of the costs associated with the Expansion Plan (approximately $41.0
million) and (ii) fund general corporate purposes, including the TeleGirardot
acquisition and any future acquisitions (approximately $23.0 million).
 
  The total cost of the Company's Expansion Plan is expected to be
approximately $181.8 million, of which approximately $7.8 million had been
financed with local bank borrowings, all of which has been repaid with
proceeds of the Offering, and approximately $1.5 million had been financed
with cash flow from operations. The remainder of the Expansion Plan,
approximately $172.5 million, is being financed from several sources
including: (i) the Offering; (ii) the sale of investments of $5.7 million;
(iii) the Vendor Financing (see "Risk Factors--Contingency of Vendor
Financing"); and (iv) the DIAN Financing (see "Description of Existing
Indebtedness--DIAN Financing"). The following table sets forth the estimated
sources and uses for the Expansion Plan Financing as of October 28, 1997:

(4) The Company was required to deposit approximately $37.9 million of the net
    proceeds of the Offering with the Central Bank. This non-interest bearing
    deposit was withdrawn before the end of the required deposit period of 18
    months by the Company to fund the Expansion Plan. Such withdrawal required
    a fee determined by applying a discount declining from 28.5% to 1.8%
    depending on the time of withdrawal of the deposit. The Company withdrew
    the deposit to finance the Expansion Plan and paid a withdrawal fee of
    $9.8 million on December 29, 1997.

                              THE EXCHANGE OFFER
 
GENERAL
 
  The Company, together with the Trust, 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 all outstanding Original Certificates properly tendered on or prior
to the Expiration Date and not withdrawn as permitted pursuant to the
procedures described below for Exchange Certificates.
 
  As of the date of this Prospectus, U.S.$150.0 million aggregate principal
amount at maturity of the Original Certificates was outstanding. This
Prospectus, together with the Letter of Transmittal, is first being sent on or
about       , 1998, to all Original Certificateholders known to the Company.
The Company's obligation to accept Original Certificates 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 Original Certificates were issued by the Trust on October 28, 1997 in
transactions exempt from the registration requirements of the Securities Act.
Accordingly, the Original Certificates may not be reoffered, resold, or
otherwise transferred in the United States unless registered pursuant to the
Securities Act or unless an applicable exemption from the registration and
prospectus delivery requirements of the Securities Act is available.
 
  In connection with the issuance and sale of the Original Certificates, the
Company entered into the Registration Rights Agreement, which requires the
Company to use its best efforts to file with the Commission a registration
statement relating to the Exchange Offer by March 27, 1998, to use its best
efforts to cause the registration relating to the Exchange Offer to become
effective under the Securities Act by May 26, 1998, and to consummate the
Exchange Offer by June 25, 1998. The Exchange Offer is being made by the
Company to satisfy its obligations with respect to the Registration Rights
Agreement. The Company filed the registration statement on April 10, 1998. As
a result of the delay in filing, additional interest has accrued on the Senior
Notes (and therefore, on the Certificates) over and above the basic interest
amount at a rate of 0.50% per annum for the period of the delay. If for any
reason, the Exchange Offer is not consummated by June 25, 1998, additional
interest will similarly accrue for the period of delay past June 25.
 
EXPIRATION DATE; EXTENSION; TERMINATION; AMENDMENT
 
  The Exchange Offer will expire at 5:00 p.m., New York City time, on       ,
1998, 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 Original Certificates, 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
Original Certificates 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 Original
Certificates 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
 
                                      33
<PAGE>
 
oral or written notice to the Original Certificateholders as promptly as
practicable in the manner set forth above with respect to an extension of the
Expiration Date.
 
  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 ORIGINAL CERTIFICATES
 
  The tender to the Company of Original Certificates by an Original
Certificateholder thereof as set forth below and the acceptance thereof by the
Company will constitute a binding agreement between the tendering Original
Certificateholder 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, an Original Certificateholder who wishes to
tender Original Certificates 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 or, in
the case of a book-entry transfer, an Agent's Message (as defined below) in
lieu of the 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 representing Original Certificates
must be received by the Exchange Agent along with the Letter of Transmittal or
Agent's Message in lieu thereof, or (ii) a timely confirmation of a book-entry
transfer (a "Book-Entry Confirmation") of such Original Certificates, 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 Original Certificateholder
must comply with the guaranteed delivery procedures described below. The term
"Agent's Message" means a message, transmitted by DTC to and received by the
Exchange Agent and forming a part of a book-entry confirmation, which states
that DTC has received an express acknowledgement from the DTC participant,
which acknowledgement states that such participant has received and agrees to
be bound by the Letter of Transmittal and that the Trust and the Company may
enforce such Letter of Transmittal against such participant.
 
  THE METHOD OF DELIVERY OF ORIGINAL CERTIFICATES, LETTERS OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE ORIGINAL
CERTIFICATEHOLDERS. 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
ORIGINAL CERTIFICATES, LETTERS OF TRANSMITTAL OR AGENT'S MESSAGE IN LIEU
THEREOF 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 Original Certificates surrendered for
exchange pursuant thereto are tendered (i) by a registered Original
Certificateholder 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 as 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 (each an "Eligible Institution"). If Original Certificates are
registered in the name of a person other than a signer of the Letter of
Transmittal, the Original Certificates 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.
 
 
                                      34

  If the Letter of Transmittal or any Original Certificates or powers of
attorney are signed by transferors, 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.
 
  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 or
delivery of an Agent's Message in lieu thereof accompanied by (i) the Original
Certificates (or a confirmation of book-entry transfer of such Original
Certificates 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 (the "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 Exchange
Certificates in exchange for Original Certificates 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 or delivery of an
Agent's Message in lieu thereof (and any other required documents) and the
tendered Original Certificates.
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Original Certificates 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 Original Certificates not properly tendered or
to not accept any particular Original Certificates which acceptance might, in
the judgment of the Company or its counsel, be unlawful. The Company also
reserves the absolute right to waive any defects or irregularities or
conditions of the Exchange Offer as to any particular Original Certificates
either before or after the Expiration Date (including the right to waive the
ineligibility of any holder who seeks to tender Original Certificates in the
Exchange Offer). The interpretation of the terms and conditions of the
Exchange Offer as to any particular Original Certificates 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 Original Certificates 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
Original Certificates for exchange, nor shall any of them incur any liability
for failure to give such notification.
 
  By tendering, each Original Certificateholder will represent to the Company
that, among other things, the Exchange Certificates acquired pursuant to the
Exchange Offer are being acquired in the ordinary course of business of the
person receiving such Exchange Certificates, 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
Exchange Certificates 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 Exchange Certificates for its own account
in exchange for Original Certificates where such Original Certificates 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 Exchange Certificates. 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 Original
Certificates at the Book-Entry Transfer Facility. DTC, 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 Original Certificates by
causing the Book-Entry Transfer Facility to transfer such Original
Certificates into the Exchange
 
                                      35
<PAGE>
 
Agent's account with respect to the Original Certificates in accordance with
the Book-Entry Transfer Facility's procedures for such transfer. Although
delivery of Original Certificates 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 or an
Agent's Message in lieu thereof 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 an Original Certificateholder desires to accept the Exchange Offer and
time will not permit a Letter of Transmittal or Original Certificates 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 Original Certificates are registered and, if
possible, the certificate numbers of the Original Certificates to be tendered,
and stating that the tender is being made thereby and guaranteeing that within
three business days after the Expiration Date the certificates for all
physically tendered Original Certificates, in proper form for transfer, or a
Book-Entry Confirmation of such Original Certificates 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 or an Agent's Message in lieu thereof (and any other
required documents). Unless Original Certificates 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 Original Certificates 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 Original Certificates to be withdrawn,
identify the Original Certificates to be withdrawn (including the amount of
such Original Certificates), and (where Original Certificates have been
transmitted) specify the name in which such Original Certificates are
registered, if different from that of the withdrawing holder thereof. If
Original Certificates 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 Original Certificates 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 Original Certificates 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 Original Certificates so
withdrawn will be deemed not to have been validly tendered for exchange for
purposes of the Exchange Offer. Any Original Certificates 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
Original Certificates 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 Original Certificates 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 Original
Certificates may be retendered by following one of the procedures described
under "--Procedures for Tendering Original Certificates" above at any time on
or prior to the Expiration Date.
 
                                      36
<PAGE>
 
ACCEPTANCE OF ORIGINAL CERTIFICATES FOR EXCHANGE; DELIVERY OF EXCHANGE
CERTIFICATES
 
  Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company will accept, promptly after the Expiration Date, all Original
Certificates properly tendered prior to 5:00 p.m., New York City time, on the
Expiration Date and will issue the Exchange Certificates promptly after such
acceptance. See "The Exchange Offer--Certain Conditions to the Exchange
Offer." For purposes of the Exchange Offer, the Company shall be deemed to
have accepted properly tendered Original Certificates 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 Original Certificate accepted for exchange, the Original
Certificateholder will receive Exchange Certificates having a principal amount
equal to that of the surrendered Original Certificates.
 
  In all cases, issuance of Exchange Certificates for Original Certificates
that are accepted for exchange pursuant to the Exchange Offer will be made
only after timely receipt by the Exchange Agent of such Original Certificates
or a timely Book-Entry Confirmation of such Original Certificates into the
Exchange Agent's account at the Book-Entry Transfer Facility, a properly
completed and duly executed Letter of Transmittal or Agent's Message in lieu
thereof and all other required documents.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
  The Exchange Offer shall not be subject to any conditions, other than that
(i) the Exchange Offer does not violate applicable law, rule, regulation or
any applicable interpretation of the Staff of the Commission (the "Staff"),
(ii) no action or proceeding is instituted or threatened in any court or by
any governmental agency which might materially impair the ability of the
Company or the Trust to proceed with the Exchange Offer and no material
adverse development has occurred in any existing action or proceeding with
respect to the Company or the Trust and (iii) all governmental approvals have
been obtained, which approvals the Company deems necessary for the
consummation of the Exchange Offer.
 
EXCHANGE AGENT
 
  Marine Midland Bank has been appointed as the Exchange Agent for the
Exchange Offer. All tendered Original Certificates, executed Letters of
Transmittal or Agent's Messages in lieu thereof 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.
 
  Marine Midland Bank also acts as Indenture Trustee under the Indenture.
 
SOLICITATION OF TENDERS
 
  The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to broker, 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 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 be beneficial
owners of the Original Certificates and in handling or forwarding tenders for
their customers.
 
  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
 
                                      37
<PAGE>
 
there has not been a 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) Original
Certificateholders 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
 
  Certificateholders who tender their Original Certificates for exchange will
not be obligated to pay any transfer taxes in connection therewith except that
Certificateholders who instruct the Company to register Exchange Certificates
in the name of, or request Original Certificates 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.
 
ACCOUNTING TREATMENT
 
  The Exchange Certificates will be recorded at the book value of the Original
Certificates 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 Exchange Certificates for
Original Certificates. Expenses incurred in connection with the issuance of
the Exchange Certificates will be amortized over the term of the Exchange
Certificates.
 
CONSEQUENCES OF FAILURE TO EXCHANGE; RESALE OF EXCHANGE CERTIFICATES
 
  Original Certificateholders who do not exchange their Original Certificates
for Exchange Certificates pursuant to the Exchange Offer will continue to be
subject to the restrictions on transfer of such Original Certificates as set
forth in the legend thereon as a consequence of the issuance of the Original
Certificates pursuant to the exemptions from, or in transactions not subject
to, the registration requirements of the Securities Act and applicable state
securities laws. Original Certificates not exchanged pursuant to the Exchange
Offer will continue to remain outstanding in accordance with their terms. In
general, the Original Certificates may not be offered or sold unless
registered under the Securities Act and under the applicable state securities
laws, 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 Original Certificates under
the Securities Act. However, if, prior to consummation of the Exchange Offer,
the Initial Purchaser holds any Certificates acquired by it and having, or
which are reasonably likely to be determined to have, the status of an unsold
allotment in the initial distribution, or any other Original Certificateholder
is not entitled to participate in the Exchange Offer, under the Registration
Rights Agreement, the Company, upon the request of the Initial Purchaser or
any such Original Certificateholder, shall simultaneously with the delivery of
Exchange Certificates in the Exchange Offer, issue and deliver to the Initial
Purchaser or any such Original Certificateholder, in exchange (the "Private
Exchange") for such Certificates held by such Initial Purchaser and any such
Original Certificateholder, a like principal amount of certificates issued by
the Trust that are identical in all material respects to the Exchange
Certificates (the "Private Exchange Certificates") (and which are entitled to
the benefits of the Trust Agreement); provided, however, the Company shall not
be required to effect such exchange if, in the written opinion of counsel for
the Company (a copy of which shall be in form and substance reasonably
satisfactory to the Initial Purchaser and be delivered to the Initial
Purchaser and any Original Certificateholder affected thereby), such exchange
cannot be effected without registration under the Securities Act. The Private
Exchange Certificates shall bear the same CUSIP number as the Exchange
Certificates.
 
  Based on certain no-action letters issued by the Staff to third parties in
unrelated transactions, the Company believes that Exchange Certificates 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 purchased Original Certificates 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
 
                                      38
<PAGE>
 
Exchange Certificates 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 Exchange Certificates. If any
holder has any arrangement or understanding with respect to the distribution
of the Exchange Certificates to be acquired pursuant to the Exchange Offer,
such holder (i) could not rely on the applicable interpretations of the staff
of the Commission and (ii) must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction. Thus, any Exchange Certificates acquired by such holder
will not be freely transferable except in compliance with the Securities Act.
A broker-dealer who holds Original Certificates 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 Exchange Certificates. Each such broker-
dealer that receives Exchange Certificates for its own account in exchange for
Original Certificates, where such Original Certificates 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 the resale of such Exchange Certificates. See
"Plan of Distribution."
 
  In addition, to comply with applicable state securities laws, the Exchange
Certificates may not be offered or sold by a Certificateholder unless they
have been registered or qualified for sale under such applicable state
securities laws or an exemption from registration or qualification is
available therefrom.
 
  Participation in the Exchange Offer is voluntary. Original
Certificateholders are urged to consult their financial and tax advisors in
making their own decisions on what action to take.
 
  As a result of the making of, and upon acceptance for exchange of all
validly tendered Original Certificates pursuant to the terms, of this Exchange
Offer, the Company will have fulfilled a covenant contained in the
Registration Rights Agreement. Any Original Certificates not tendered and
accepted in the Exchange Offer will remain outstanding and will be entitled to
all of the same rights and will be subject to all of the same limitations
applicable thereto under the Trust Agreement (except for certain rights to be
registered under the Act which terminate upon consummation of the Exchange
Offer). All untendered Original Certificates, and all Private Exchange
Certificates will be subject to the restrictions on transfer set forth in the
Indenture, except that the holders of Private Exchange Certificates will in
certain circumstances have rights to have their Private Exchange Certificates
registered under the Act for resale. To the extent that Original Certificates
are tendered and accepted in the Exchange Offer, an Original
Certificateholder's ability to sell untendered Original Certificates could be
adversely affected.
 
  The Company may in the future seek to acquire untendered Original
Certificates in open market or privately negotiated transactions, through
subsequent exchange offers or otherwise. The Company has no present plan to
acquire any Original Certificates which are not tendered in the Exchange
Offer.

                       SELECTED FINANCIAL AND OTHER DATA
 
  The Company was incorporated in 1993 and commenced offering telephone
services, through its operating subsidiary TelePalmira, in September 1995.
Accordingly, the Company has no commercial operating history prior to such
time, and results for 1995 are not directly comparable to those of 1996. The
Company was in a preoperating stage prior to September 1, 1995 and capitalized
all of its net expenses as deferred charges; thus, no statements of income are
presented for 1993 and 1994. The selected statement of income data for each of
the years ended December 31, 1995 and 1996 and the nine months ended September
30, 1997, and the selected balance sheet data as of December 31, 1994, 1995
and 1996 and September 30, 1997 have been derived from financial statements
audited by Price Waterhouse, independent accountants. The consolidated balance
sheets at December 31, 1996 and September 30, 1997 and the related statements
of income and of cash flows, of changes in financial position and of changes
in shareholders' equity for the two years ended December 31, 1996 and the nine
months ended September 30, 1997, and notes thereto, appear elsewhere herein.
The report of Price Waterhouse which also appears herein contains an
explanatory paragraph relating to a change in the method of depreciation as
described in Note 7 to the Consolidated Financial Statements. The selected
balance sheet data at December 31, 1993 have been derived from unaudited
consolidated financial statements of the Company. 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 Consolidated Financial Statements of the Company,
including the notes thereto, included elsewhere in this Prospectus.
 
  The Consolidated Financial Statements included herein have been prepared in
conformity with Colombian GAAP (including restatement of the financial
information in constant pesos as of September 30, 1997), which differs in
certain significant aspects from U.S. GAAP. Note 28 to the Consolidated
Financial Statements provides a discussion of the principal differences
between Colombian and U.S. GAAP as they relate to the Company and a
reconciliation of net income and shareholders' equity for the Company as of
and for the years ended December 31, 1995 and 1996 and as of and for the nine
months ended September 30, 1997, to amounts calculated in accordance with U.S.
GAAP.
 
  Dollar equivalent information set forth below has been included solely for
the convenience of the reader, and is translated from Pesos at the
Representative Market Rate in effect on September 30, 1997 of Ps1,246.27 to
one Dollar. Such translation should not be construed as a representation that
the Peso amounts represent, or have been or could be converted into, Dollars
at that rate or any other rate.
 
  Unless otherwise indicated, all financial information included in this
Prospectus has, for comparability purposes, been restated in constant Pesos as
of September 30, 1997 by indexing historical amounts using the MCPI. Although
the restatement of nominal Pesos into constant Pesos lessens the distorting
effect that an inflationary environment has on comparisons of the Consolidated
Financial Statements over time, such restatement does not wholly eliminate
those distortions and evaluation of period-to-period trends may be difficult.
See "Risk Factors--Corporate Disclosure and Accounting Standards" and "Risk
Factors--Inflation."

(1) For Colombian GAAP purposes, as of January 1, 1996, TelePalmira changed
    from the straight-line to the reverse sum of the years digits' method of
    computing depreciation which had the effect of decreasing 1996
    depreciation (and increasing 1996 income before income taxes and minority
    interest) by Ps914,548 ($734) and increasing 1996 net income by Ps548,728
    ($440). For U.S. GAAP purposes, all periods use the straight-line method.
(2) EBITDA is defined as operating income (loss) plus depreciation and
    amortization and plus lease expense related to the Vendor Financing under
    Colombian GAAP. Under U.S. GAAP, the Vendor Financing is treated as debt
    and therefore the associated cost is treated as interest expense and
    principal payment rather than lease expense. Although EBITDA is not a
    measure of performance calculated in accordance with Colombian or U.S.
    GAAP, the Company has included such data because it is used by certain
    investors to determine the Company's ability to meet debt service
    requirements. Such data should not be considered as an alternative to net
    earnings as an indicator of the Company's operating performance or as an
    alternative to cash flows from operating activities as a measure of
    liquidity.
(3) Capital expenditures consist of purchases of properties, plant and
    equipment as reflected in the Company's consolidated statements of cash
    flows.
(4) Total Indebtedness is calculated in accordance with the definition of
    "Indebtedness" under the Indenture, which includes short-term debt, long-
    term debt, capital lease obligations, lease payments under the Vendor
    Financing (which are treated as operating leases under Colombian GAAP, but
    are capitalized under U.S. GAAP), and the Company's obligations under the
    DIAN Financing.
(5) For purposes of computing the deficiency of earnings to fixed charges,
    "earnings" consist of income (loss) before income taxes, minority
    interests and fixed charges, excluding capitalized interest. Fixed charges
    consist of interest on all indebtedness (whether capitalized or expensed)
    and that portion of operating lease expenses deemed to be interest
    expense.
(6) Penetration represents the number of installed lines per 100 people. In
    Cartago, Jamundi and Yumbo, penetration includes the installed lines of
    municipal competitors as of December 31, 1996 of approximately 10,000
    lines, 5,200 lines and 5,500 lines as per the Company's estimates,
    respectively.
(7) Short-term debt includes current portion of long-term debt, current
    portion of capital lease obligations and short-term debt.
(8) Long-term debt includes long-term debt and capital lease obligations.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
 
  The following is a discussion of the consolidated financial condition and
results of operations of the Company as of and for the years ended December
31, 1995 and December 31, 1996 and as of and for the nine months ended
September 30, 1997. The discussion should be read in conjunction with the
Consolidated Financial Statements of the Company and the notes thereto
included elsewhere in this Prospectus. The Consolidated Financial Statements
have been prepared in accordance with Colombian GAAP, which differs in certain
significant respects from U.S. GAAP. Note 28 to the Company's Consolidated
Financial Statements provides a reconciliation to U.S. GAAP of the Company's
net income (loss) and shareholders' equity (deficit) for as of and for the
years ended December 31, 1995 and 1996 and as of and for the nine months ended
September 30, 1997. Unless otherwise indicated, the financial information has
been presented in constant Pesos as of the latest balance sheet date of the
Company (September 30, 1997). Dollar amounts are translated from Pesos amounts
at the Representative Market Rate on September 30, 1997, which was 1,246.27
Pesos to one Dollar.
 
GENERAL
 
  The Company is the largest private telephone company in Colombia, providing
telephone service to both business and residential subscribers. The Company
(excluding TeleGirardot), currently owns and operates telephone systems
serving seven cities, with an aggregate population of 2.9 million people,
located in the southwestern region of Colombia. As of December 31, 1997, such
systems provided service to an aggregate of approximately 101,500 subscribers
and had an average penetration of 18 lines per 100 people.
 
  The Company is implementing its Expansion Plan designed to satisfy the
significant demand and growth for telephone lines in each of its markets.
Management intends to substantially increase the number of lines installed
from 56,800 at the date of acquisition of each of the systems to approximately
222,200 lines by the completion of the Expansion Plan by December 31, 1998. As
of February 28, 1998 the Company, in conjunction with Siemens, had completed
the installation of approximately 105,100 new lines, or approximately 64% of
the lines to be installed pursuant to the Expansion Plan.
 
  For the Company's expansion plan with respect to TeleGirardot, see
"Prospectus Summary--Recent Developments."
 
  The Company generates revenues by providing telephone services to its
commercial and residential subscribers. The Company's sources of revenue
consist of: (i) basic fixed charges based either on the predecessor telephone
operator or the existing competitive tariff structure, (ii) local usage
charges based on the number of minutes used per month; (iii) access charges
for national and international long distance based on the incoming and
outgoing calls from the Company's network system; (iv) the sale of equipment
to subscribers; (v) value-added services such as video conference calling and
voice mail; and (vi) connection fees from each new subscriber connected to the
Company's network. Various local institutions are available to finance
subscribers' connection fees. Typically, Transtel installs a line and
subsequently sells the associated connection fee receivable to local financial
institutions on a non-discounted basis. In addition, the Company is expected
to generate additional revenues from its subscribers accessing the Internet.
The Company's subscribers will be expected to pay a monthly service fee and a
monthly usage fee to access the Internet. All of the Operating Companies will
be able to provide Internet access by May 1, 1998.
 
  The Company expects that connection fees will continue to comprise a
significant portion of the Company's near-term revenues as a result of the
expected growth in the Company's subscriber base. The Company believes that as
subscribers are added to the network and existing demand is satisfied, the
composition of revenues will shift, resulting in local, national and long
distance usage comprising the majority of the Company's revenues. In addition,
the Company expects that value-added services will also comprise a more
significant portion of future revenues driven by Internet access and other
telephone services such as videoconference calling, voice mail and call
waiting.

FACTORS THAT WILL AFFECT FUTURE RESULTS OF OPERATIONS--PRINCIPAL SOURCES OF
REVENUE AND EXPENSES
 
  The Company has formulated a business plan based on, among other
assumptions, the following assumptions regarding penetration, call volume,
usage patterns, capital expenditures and churn, all of which could
significantly affect its future results of operations.
 
  Penetration. In 1995, Colombia had an average penetration of approximately
14.0 lines per 100 people. At the time the Company initiated the development
and operation of telephone service in the municipality of Palmira, the
municipality had a penetration of approximately 4.9 lines per 100 people. The
Company has since increased Palmira's subscriber base by 220% from 15,600 to
50,100 as of December 31, 1997, representing a penetration of approximately 16
lines per 100 people. The Company believes that it will be able to complete
its network development in Palmira by June 30, 1998. Based on the Company's
experience in Palmira, the Company expects to achieve its complete network
build-out and subscriber addition by the end of 1998. The Company has designed
its Expansion Plan in order to accommodate the existing unmet demand and the
projected growth based on its extensive market studies that include door-to-
door surveys. Following completion of the Expansion Plan, and assuming a fully
subscribed network, the Company expects to have a penetration of approximately
22.8 lines per 100 people.
 
  Call Volume/Usage. Charges for local and domestic long-distance service vary
with the price per minute and the number of minutes consumed on a monthly
basis. The charge per minute depends on the time of day, the day of the week
and the duration of calls. Telephone usage also depends on the number of lines
in service, the volume of minutes, the number of new lines to be installed and
the applicable tariffs. Telephone usage differs for residential, commercial
and rural subscribers.
 
  Telephone usage in Colombia in terms of minutes has grown to 75.9 billion
minutes per annum in 1996, from 32.2 billion minutes per annum in 1994,
representing a compound annual growth rate ("CAGR") of 53.5%. Total usage for
1996 included 70.4 billion minutes of local calls, 4.9 billion minutes of
national long distance and 532 million minutes of international long distance.
According to the Ministry of Communications the average annual consumption per
subscriber in 1996 (including both residential and business subscribers) was
as follows: (i) 14,652 minutes (1,221 minutes per month) of local calls; (ii)
1,032 minutes (86 minutes per month) of domestic long distance calls; and
(iii) 110 minutes (9 minutes per month) of international long distance calls.
The Company believes future usage patterns in Colombia, including the
Company's markets, will be consistent with historical usage patterns.
 
  Revenues. The Company's revenues are comprised of: (i) connection fees; (ii)
basic fixed charges; (iii) local usage charges; (iv) access charges of
national and international long distance calls; (v) the sale of equipment to
subscribers; and (vi) charges for value-added services. Telephone rates in
Colombia, excluding connection fees, are subject to inflationary adjustments
on a monthly basis in accordance with regulations from the CRT. For fiscal
years 1997 and 1996, the Colombian Consumer Price Index increased 17.4% and
19.5%, respectively, while basic telephone rates in constant pesos increased
approximately 3.6% and decreased 2.4%, respectively. The Company collects its
service fees from its customers every month. The local operator bills and
collects a fixed monthly fee, local usage, long distance and cellular revenues
from each customer. The Company retains its interconnection revenues for the
utilization of the Company's network in any long distance and cellular
incoming or outgoing call. In addition, the CRT sets tariffs either in
accordance with the historical costs of the telephone system or levels
established by the competition. This law has greatly benefited the Company by
allowing management to set its tariffs in accordance with its competitors'
higher historical operating costs, rather than the Company's much lower cost
of operations.
 
  Tariffs. Tariffs and usage patterns differ significantly for the three major
categories of subscribers in Colombia: (i) residential, (ii)
commercial/industrial; and (iii) rural subscribers. In addition, Colombia
imposes a progressive tariff structure whereby higher income customers are
charged a higher tariff to subsidize lower income subscribers. Tariffs are
based on the economic status for which the subscriber qualifies. Commercial
customers are segregated into middle market and industrial classifications.
Industrial subscribers may be charged
 
                                      44
<PAGE>
 
a higher tariff and such pricing adjustments are left to the discretion of the
service provider. Rural customers are usually charged the highest tariffs in
order to incentivize the provision of service to such customers.
 
  The following table sets forth current tariff information for residential
and commercial customers of the Company in Palmira.

     Long Distance Charges................    Ps34/minute        Ps34/minute
</TABLE>
 
  Connection Fees. Tariffs with respect to installation or connection as of
December 31, 1997 ranged in each of the Operating Companies from Ps125,000-
664,000 for residential subscribers and Ps486,000-664,000 for commercial
subscribers. As of December 31, 1997, the top 25 telephone operators in
Colombia had an average residential connection fee of approximately Ps339,941
and a commercial connection fee of approximately Ps507,827. The Company set
its connection tariffs in each municipality based either on its predecessor
telephone operator or the competitive tariff structure in each market. As of
December 31, 1997, the Company, based on the total number of lines sold,
charged an average connection fee on all residential and commercial
subscribers of Ps366,000 in Palmira.
 
  Under Colombian GAAP, the Company recognizes income from connection charges
when full payment is received from the customer or when the customer signs the
promissory note and makes the initial payment on the connection fee. These
events may occur prior to the time that the customer is connected to the
network and becomes a subscriber.
 
  Basic Charges. The Company's basic charges vary by municipality and are
negotiated based either on the predecessor telephone operator or the existing
competitive tariff structure. In 1997, Palmira's average monthly basic fee for
residential and commercial customers was approximately Ps3,950 as compared to
the national average for the top 25 operators in Colombia which was
approximately Ps4,100. The following chart illustrates the Company's
residential and commercial basic monthly charges as of December 1997 for the
Company's Operating Companies.

</TABLE>
 
  Local Usage Charges. The Company collects a monthly local usage charge from
its customers. Local usage is based on the number of minutes generated by each
subscriber, valued at the price per minute existing at the time of billing. In
1997, the Company generated approximately 883 minutes per month per average
residential and commercial subscriber and had a monthly usage charge of Ps5
per minute in Palmira.
 
  Long Distance Charges. The Company collects long distance charges based on
the number and duration of calls. Long distance access tariffs are set by the
CRT and are identical for all operators throughout Colombia. In 1997, the
Company generated approximately 344 minutes per month per average residential
and commercial subscriber and had a monthly usage charge of Ps34 per minute in
Palmira.
 
  Other Revenues. Other revenues consist of, among other things, the sale of
telephone equipment to subscribers (provided by Siemens), telephone books and
public telephones. In addition, value-added services such as video conference
calling and Internet access are expected to generate a significant portion of
the Company's revenues in the future. The Company intends to offer competitive
tariffs for the usage of such value-added services. In addition, the Company
expects to complement its value-added services by increasing the number of
lines of its existing subscriber base that may need to have a separate line
for a fax machine or the Internet instead of sharing it with the main
telephone line.
 
 
                                      45
<PAGE>
 
  Operating Costs. The Company anticipates that it will incur operating costs
from the following primary activities: (i) operations, (ii) general
administrative expenses and (iii) sales and marketing. In each such category,
the Company's primary cost of operation will consist of personnel.
Substantially all of the expenses incurred by the Company during its
development period were deferred as preoperating costs and consisted primarily
of expenses associated with due diligence, research and execution of the
Company's acquisition strategy and formation of the Company's corporate
infrastructure. Such cumulative deferred costs (before accumulated
amortization) were Ps4.5 billion, Ps5.7 billion and Ps6.0 billion at December
31, 1995, December 31, 1996 and September 30, 1997, respectively.
 
  Operating Expenses. Operating expenses consist of costs associated with
customer service, network operations and other operation costs. Although
initially the costs of operations for the Company will be limited by the turn-
key contracts that the Company has with Siemens, the Company expects that its
operating expenses will increase due to the increasing number of customers
requiring installation and general service. Subsequently, operating expenses
will consist predominantly of general maintenance and upkeep.
 
  Administrative Expenses. Administrative expenses include engineering,
network implementation and information technology expenses, finance and
billing, management and miscellaneous costs. Administrative expenses are
expected to increase during the Expansion Plan. During fiscal 1996 and the
nine months ended September 30, 1997, the Company hired additional personnel
to oversee and supervise Siemens' construction of the networks for Palmira,
Jamundi and Yumbo. In the year ended December 31, 1996 and the nine months
ended September 30, 1997, these additional workers are reflected in
incremental administration costs of approximately Ps367.9 million ($295,200)
and Ps450.3 million ($361,300) respectively. These workers are temporary and
the costs associated with their employment are expected to decrease following
completion of the networks.
 
  Sales and Marketing Expenses. Sales and marketing expenses, consisting of
costs relating to the Company's sales and marketing department, advertising,
direct mailing programs and door-to-door survey activities, are expected to
remain constant throughout the Expansion Plan and to decrease thereafter,
reflecting costs associated with the launch and rollout of the Company's
services in each of its Operating Companies. Sales and marketing expenses are
expected to vary based on the size of each market. In 1997, in Palmira, the
average selling and marketing expense per new subscriber was approximately
Ps39,200. The Company expects the average sales and marketing expenses per new
subscriber to be consistent with its experience in Palmira.
 
  Capital Expenditures. The Expansion Plan is projected to require aggregate
capital expenditures of approximately Ps226.6 billion ($181.8 million), of
which approximately 70.0% is related to fixed price, equipment purchase
agreements and turn-key installation contracts. As of September 30, 1997,
approximately Ps9.7 billion ($7.8 million) has been financed with local bank
borrowings, all of which have been repaid with proceeds of the Offering, and
approximately Ps1.9 billion ($1.5 million) has been financed with cash flow
from operations. The Expansion Plan will require capital expenditures in each
of the Company's markets and management intends to fully finance the Expansion
Plan with the Expansion Plan Financing. See "Prospectus Summary--Expansion
Plan" and "Use of Proceeds." Upon completion of the Expansion Plan, the
Company will operate a fully digital internal plant and a fiber optic primary
network. This technology is long-lived and requires minimal maintenance. For
the nine months ended September 30, 1997, the Company incurred minimal
maintenance expense per line due to the fact that the networks are new. The
Company expects that its annual maintenance expense will increase to
approximately Ps10,890 per line and that new lines will cost an additional
capital expenditure of Ps317,799 per line once the network is fully built. The
Company has contracted Siemens for the execution of its Expansion Plan.
Siemens will construct newly designed networks and install modern, high
quality equipment in each of the Company's systems. Siemens is expected to
complete the Expansion Plan by December 31, 1998. See "Description of Existing
Indebtedness--Global--Siemens Arrangements."
 
  Churn. Churn consists of both residential and business customers that change
premises, disconnect telephone service once established, switch to other
service providers, if and where available, or terminate the Company's
services. In the year ended December 31, 1996, and the nine months ended
September 30, 1997, the Company experienced an annual average churn rate of
less than 0.90% and 0.50%, respectively, in the
 
                                      46
<PAGE>
 
municipality of Palmira. Management attributes the low churn rate to (i) the
significant unmet demand and the lack of quality telephone service providers
that has resulted in multi-year waiting lists, (ii) the significant investment
resulting from the connection fee paid by the subscriber in order to initiate
service and (iii) the Company's ability to provide high quality telephone
services with significant emphasis on customer service. Management believes
that these fundamentals exist in the markets in which it operates and expects
the churn rate to remain relatively low.

  The following is a discussion of the consolidated results of operations of
the Company for the nine months ended September 30, 1997, the year ended
December 31, 1996 and the four months ended December 31, 1995 (the Company
commenced commercial operation on September 1, 1995).

NINE-MONTH PERIOD ENDED SEPTEMBER 30, 1997 COMPARED TO THE YEAR ENDED DECEMBER
31, 1996
 
  Revenues. The total revenues for the nine months ended September 30, 1997
increased by Ps6.080 billion, or 52.6%, to Ps17.640 billion from Ps11.560
billion in the year ended December 31, 1996 ("Annual 1996"). The increase in
revenues for the first nine months of 1997 was mainly attributable to the
increase in connection fees revenues associated with the increase in the
number of new subscribers. The number of subscribers increased from 29,528 at
December 31, 1996 to 92,009 at September 30, 1997 because of the beginning of
operations in the municipalities of Cartago, Popayan, Jamundi, Buga and Yumbo
during 1997. The number of new subscribers at TelePalmira increased during the
same period because of its increase in capacity and the modernization of the
telephone infrastructure. Although installation of switching infrastructure
and antennas was substantially completed at Unitel Wireless in the fourth
quarter of 1997, there was interference from unauthorized radio spectrum
users, which was subsequently removed by the Ministry of Communications. This
delayed the Company's launch of operations at Unitel Wireless until the first
quarter of 1998.
 
  Connection revenues in the nine months ended September 30, 1997 increased by
Ps2.609 billion from Ps5.465 billion in Annual 1996 to Ps8.074 billion. Other
operating revenues, including basic monthly charges, local usage charges,
long-distance charges and other fees for the nine months ended September 30,
1997 increased by Ps3.470 billion from Ps6.096 billion in Annual 1996 to
Ps9.566 billion in the nine months ended September 30, 1997. The increase in
other operating revenues for the nine months ended September 30, 1997 is
attributed to the increase in the number of subscribers and also in the higher
usage associated with that increase.
 
  Costs and Expenses. The costs and expenses for the nine months ended
September 30, 1997 increased by Ps2.887 billion, or 41.5%, to Ps9.840 billion
from Ps6.953 billion in Annual 1996. The increase is primarily attributable to
the increase in the operating costs and the administrative and marketing
expenses due to the increase in the number of subscribers and the maintenance
and expansion of the telephony infrastructure in the cities of Palmira,
Cartago, Yumbo, Jamundi, Buga and Popayan.
 
  Operating costs for the nine months ended September 30, 1997 increased by
Ps1.541 billion from Ps2.457 billion in Annual 1996 to Ps3.998 billion, mainly
as a result of an increase in salary costs, benefits and other labor expenses
related to the operations as well as an increase in lease expenses.
 
  Administrative expenses for the nine months ended September 30, 1997
increased by Ps1.120 billion to Ps4.858 billion from Ps3.738 billion in Annual
1996. The increase was mainly attributable to the increase in consulting fees,
studies and research, and depreciation and amortization.
 
  Marketing expenses for the nine months ended September 30, 1997 increased by
Ps0.225 billion to Ps0.983 billion from Ps0.758 billion in Annual 1996. The
increase in marketing expenses was attributable to the higher commissions paid
to the sales agents, the increase in the lines sold and the increase in other
publicity and marketing costs.
 
  EBITDA. EBITDA for the nine months ended September 30, 1997 increased by
Ps4.090 billion from Ps6.664 billion in Annual 1996 to Ps10.754 billion as a
result of all of the above factors.
 
  Operating Income. Operating income for the nine months ended September 30,
1997 increased by Ps3.193 billion from Ps4.607 billion in Annual 1996 to
Ps7.800 billion from Ps4.607 billion in annual 1996. The increase was mainly
attributable to the increase in revenues as a result of the larger number of
subsidiaries in operation and in subscribers, net of the increase in costs and
expenses described above.

</TABLE>
 
  Net nonoperating expense increased from Ps1.034 billion for Annual 1996 to
Ps5.315 billion in the nine months ended September 30, 1997. The increase was
mainly due to the higher interest expense on increased average borrowings of
the Company for the nine months ended September 30, 1997, net of an increase
in interest income, and an increase in exchange losses. Interest expense
increased from Ps1.891 billion in Annual 1996 to Ps4.449 billion in the nine
months ended September 30, 1997. An additional Ps7.545 billion of interest
costs were incurred and recorded as deferred charges in the nine months ended
September 30, 1997 as compared to Ps6.118 billion during Annual 1996. The
average borrowings increased during the nine months ended September 30, 1997
because of implementing the Expansion Plan, including operations in five new
municipalities. More interest income from temporary investments in Pesos
occurred in the nine months ended September 30, 1997 due to higher average
balances. The increase in net exchange losses is due to higher U.S. dollar-
denominated borrowings during the nine months ended September 30, 1997.
 
  Net Monetary Inflation Adjustment Income. Net monetary inflation adjustment
income for the nine months ended September 30, 1997 increased by Ps0.621
billion to Ps2.846 billion from Ps2.225 billion in Annual 1996 as a result of
the impact of inflationary adjustments on the higher balance of nonmonetary
assets as well as on the income, expense and shareholders' equity accounts.
 
  Income Tax Expense. Income tax expense for the nine months ended September
30, 1997 increased by Ps1.768 billion to Ps2.087 billion from Ps 0.319 billion
in Annual 1996 as a result of the increase in interest income which is not
exempt from income tax and the fact that the operating subsidiaries are only
90% exempt in calendar 1997. See Note 15 of the Consolidated Financial
Statements.
 
  Minority Interest. Minority interest for the nine months ended September 30,
1997 increased by Ps0.162 billion to Ps2.391 billion from Ps2.229 billion for
Annual 1996 because of the increased net income of the operating subsidiaries.
 
  Net Income. Net income decreased by Ps2.396 billion from Ps3.249 billion for
Annual 1996 to Ps0.853 billion for the nine months ended September 30, 1997 as
a result of the factors discussed above.

RESULTS OF OPERATIONS FROM INCEPTION THROUGH THE YEAR ENDED DECEMBER 31, 1996
 
  The Annual 1996 financial statements reflect the Company's first full year
of operation, and are therefore not directly comparable to the 1995 fiscal
year statements, which only include the four months of operations of Palmira,
the Company's sole system at that time.
 
  Revenues. Revenues for Annual 1996 increased by Ps9.201 billion or 390% to
Ps11.560 billion from Ps2.359 billion for the four months ended December 31,
1995 ("Annual 1995"). The increased revenues in Annual 1996 were primarily
attributable to the increase in connection fees associated with the increase
in the number of new subscribers. Subscribers in Palmira, the Company's only
system providing telecommunication services during this period, increased by
32.3% to 29,500 at December 31, 1996 from 22,300 at December 31, 1995 (15,600
at September 1, 1995).
 
  Connection fees for Annual 1996 increased by Ps4.775 billion to Ps5.465
billion from Ps0.690 billion in Annual 1995. While there was an increase in
subscribers in the four months ended 1995 and for the twelve months ended
December 31, 1996, 6,382 and 3,730 of these subscribers, respectively, had
paid their connection fees to the municipality prior to the Company's
acquisition and therefore paid no additional connection fees to the Company.
Other revenues, including local usage fees, basic fees, long distance fees and
other fees for Annual 1996 increased by Ps4.427 billion to Ps6.096 billion
from Ps1.669 billion in Annual 1995. The increase in other revenues in Annual
1996 resulted primarily from the increase in the number of subscribers and
usage associated with such growth.
 
  Costs and Expenses. Cost and expenses for Annual 1996 increased by Ps5.829
billion to Ps6.953 billion from Ps1.124 billion for Annual 1995. The increase
in costs and expenses in Annual 1996 was primarily attributable to the
increase in operating costs, administrative expenses and marketing expenses
associated with the increased number of subscribers in Palmira and the
maintenance and expansion of the Company's system in Palmira.
 
  Operating costs for Annual 1996 increased by Ps1.774 billion to Ps2.457
billion from Ps0.683 billion for Annual 1995 primarily as a result of the
increase in salaries, benefits and other labor payments and rent due to the
twelve months of operation in Fiscal 1996 as compared to four months in Annual
1995.
 
  Administrative expenses for Annual 1996 increased by Ps3.383 billion to
Ps3.738 billion from Ps0.355 billion for Annual 1995. This increase was
primarily as a result of the increase in consultant fees, studies and
investigations; service, maintenance and repairs; and depreciation and
amortization.
 
  Marketing expenses for Annual 1996 increased by Ps0.672 billion to Ps0.758
billion from Ps0.086 billion for Annual 1995. Selling expenses increased as a
result of the increase in commissions paid to salespeople and marketing and
advertising expenses.
 
  The increase in overall costs and expenses resulted primarily from the
twelve months of operations of the Company in Annual 1996 as compared to four
months in Annual 1995.
 
  EBITDA. EBITDA for Annual 1996 increased by Ps5.047 billion to Ps6.664
billion from Ps1.617 billion for Annual 1995 as a result of factors discussed
above.
 
  Operating Income. Operating income for Annual 1996 increased by Ps3.372
billion to Ps4.607 billion from Ps1.235 billion for Annual 1995. This increase
was primarily attributable to the increase in revenues associated with the
twelve months of operations of the Company in Annual 1996 as compared to four
months in Annual 1995, offset partially by the increase in operating costs and
expenses as discussed above.

</TABLE>
 
  Nonoperating income (expenses), decreased from income of Ps0.079 billion for
Annual 1995 to an expense of Ps1.034 billion for Annual 1996. This decrease
was primarily a result of the increase in interest expense associated with the
higher levels of debt in Annual 1996 as compared to Annual 1995. Interest
expense increased from Ps0.277 billion in Annual 1995 to Ps1.891 billion in
Annual 1996. An additional Ps6.118 of interest costs were incurred and
recorded as deferred charges during Annual 1996 as compared to Ps1.273 billion
during Annual 1995. Nonoperating income (expenses) also consists of interest
income earned on short-term Peso-denominated investments. The Company was able
to invest its excess cash from the float created in the collection of local,
long distance and cellular revenues from subscribers. Net exchange gains of
Ps0.235 billion occurred for the first time in Annual 1996.
 
  Net Monetary Inflation Adjustment Income (Loss). Net monetary inflation
adjustment income (loss) for Annual 1996 increased by Ps2.164 billion to
Ps2.225 billion from a loss of Ps0.061 billion for Annual 1995 primarily as a
result of the impact of inflation adjustments to larger balances in
properties, plant and equipment and deferred charges because of the expansion
of the Company.
 
  Income Tax Expense. Income tax expense for Annual 1996 increased to Ps0.319
billion. The low level of income taxes paid reflects the special status under
Law 142 for new telephone service providers. See Note 15 of the Consolidated
Financial Statements.
 
  Minority Interest. Minority interest for Annual 1996 increased by Ps1.728
billion to Ps2.229 billion from Ps0.501 million for Annual 1995. This increase
was attributable to the municipality of Palmira's minority ownership (40%) in
TelePalmira and minority interest increased primarily as a result of the
twelve months of operations of TelePalmira in Annual 1996 as compared to four
months in Annual 1995.
 
  Net Income. Net income for Annual 1996 increased by Ps2.497 billion to
Ps3.249 billion from Ps0.752 billion for Annual 1995 as a result of the
factors discussed above.

LIQUIDITY AND CAPITAL RESOURCES
 
  The fixed landline telephone business is a capital intensive business which
requires substantial investment to acquire and upgrade the telephone networks
in each of the Company's markets. From inception through September 30, 1997,
the Company expended an aggregate of approximately Ps32.0 billion to acquire
various interests in each of its existing telephone systems. In addition, the
Company has required significant capital for personnel hiring and training,
systems infrastructure development, sales and marketing programs and the
initial build-out under the Expansion Plan. To date, the primary sources of
capital have consisted of equity contributions by the Company's shareholders,
debt financing from local Colombian banks, cash flow generated by the Palmira
operating system, certain Vendor Financing in the form of non-capitalized
leases (which are treated as capitalized leases under U.S. GAAP), and the
Senior Notes.
 
  Net cash used in operating activities during the nine months ended September
30, 1997 was Ps11.867 billion as compared to Ps7.543 billion for Annual 1996.
The increase in cash consumed by operations for the nine months ended
September 30, 1997 was primarily due to an increase in accounts receivables
and deferred charges due to the Company's expansion. Net cash used in
investing activities during the nine months ended September 30, 1997 was
Ps49.680 billion as compared to Ps8.954 billion provided in Annual 1996. Cash
used in investing activities principally relates to the construction of new
network systems, the acquisition of several operating systems and the upgrade
of existing network systems. In addition, cash used in investing activities
includes the purchase of short-term and long-term investments. Net cash
provided by financing activities during the nine months ended September 30,
1997 was Ps49.401 billion as compared to Ps27.372 billion in Annual 1996. Cash
provided by financing activities during the nine months ended September 30,
1997 primarily represents net borrowing of Ps18.627 billion of debt. As of
September 30, 1997, the Company's borrowings were Ps60.362 billion, all of
which is presented as long-term because of the refinancing by the Senior Notes
on October 28, 1997. As of September 30, 1997, the Company's borrowings
denominated in Dollars were Ps37.502 billion and the Company's borrowings
denominated in Pesos were Ps22.860 billion. The Company also has obligations
under leases which are not capitalized in accordance with Colombian GAAP, but
are required to be capitalized under U.S. GAAP. See Notes 16 and 28 to the
Consolidated Financial Statements. In July 1997, the shareholders of the
Company invested Ps30.872 billion in the Company for substantially all of the
Equity Contribution.
 
  The Company's principal liquidity requirements will be for the Expansion
Plan, debt service (primarily on the Senior Notes), working capital and
general corporate purposes, including future acquisitions. The Expansion Plan
is projected to require aggregate capital expenditures of approximately $181.8
million, approximately 70.0% of which will be incurred pursuant to the fixed
equipment purchase and turn-key installation contracts. The Company expects to
complete the build-out of the Expansion Plan by December 31, 1998. As of
September 30, 1997, approximately $7.8 million has been financed with proceeds
of local bank borrowings, all of which was repaid with proceeds of the
Offering, and approximately $1.5 million has been financed with cash flow from
operations. The remainder of the Expansion Plan, approximately $172.5 million,
has been or will be financed with (i) approximately $41.0 million of the
proceeds of the Offering; (ii) approximately $102.7 million of Vendor
Financing (see "Risk Factors--Contingency of Vendor Financing"); (iii) the
sale of investments of $5.7 million and (iv) approximately $23.1 million of
DIAN Financing (see "Description of Existing Indebtedness--DIAN Financing").
See "Use of Proceeds." As of February 28, 1998, the Company had incurred
approximately $118.2 million of capital expenditures relating to the Expansion
Plan and expects to incur the remainder, approximately $63.6 million, by the
end of 1998.
 
  As a result of the Offering, the Vendor Financing, the DIAN Financing and
the incurrence of certain other indebtedness, the Company will be required to
satisfy certain debt service requirements. Following the disbursements in May
and November 1998 and 1999 of all the proceeds in the Escrow Account, a
substantial portion of the Company's cash flow will be utilized to service the
Senior Notes, the Vendor Financing and the DIAN Financing. The Senior Notes
will require semi-annual interest payments of approximately $9.4 million and
the Vendor Financing will require semi-annual interest and principal payments
of approximately $7.2 million. In addition, the DIAN Financing will require
semi-annual principal payments of approximately $2.3 million. The ability of
the Company to make payments of principal and interest will be largely
dependent upon its future performance. Many factors, some of which will be
beyond the Company's control (such as prevailing
 
                                      52
<PAGE>
 
economic conditions), may affect its performance. There can be no assurance
that the Company will be able to generate sufficient cash flow to cover
required interest and principal payments when due on its indebtedness. If the
Company is unable to make principal and interest payments in the future, it
may, depending upon the circumstances which then exist, seek additional equity
or debt financing, attempt to refinance its indebtedness or sell all or part
of its business or assets to raise funds to repay its indebtedness.
 
  The Company formed TeleGirardot, a 60% owned subsidiary, on December 31,
1997 by contributing Ps8.898 billion in cash to the subsidiary. The
municipality of Girardot contributed the net assets of its telephone network
(which had approximately 23,500 subscribers) with a fair market value of
Ps5.932 billion to TeleGirardot in exchange for a 40% interest in
TeleGirardot. See Note 27 to the Consolidated Financial Statements.
 
  The Company also expects to consider additional acquisitions that fit its
strategic plans. Although the Company has had discussions concerning such
potential acquisitions, to date, no agreements have been reached with regard
to any particular transaction. Any such acquisitions that the Company might
consider are likely to require additional equity and/or debt financing, which
the Company will seek to obtain as necessary. Management believes that, based
on its current operations and anticipated growth resulting from the Expansion
Plan, cash flow from the Expansion Plan Financing, cash flow from operations
and other sources of funds, including local borrowings, it will have adequate
funds to complete the Expansion Plan and to meet its future cash requirements.
 
ACCOUNTING FOR INFLATION
 
  As a Colombian company, the Company maintains its financial records in
Pesos. Colombian GAAP requires that the financial statements of Colombian
companies be adjusted to account for inflation. The inflation rate for the
nine months ended September 30, 1997 was 14.10%. Financial statements are
adjusted for the effects of inflation on the basis of changes in the Colombian
MCPI. This index is applied on a one-month lagging basis to nonmonetary assets
and liabilities, shareholders' equity, revenues and expense accounts. Monetary
balances are not adjusted because they reflect the purchasing power of the
currency on 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 same date. The resulting net gain or loss from exposure to inflation is
reflected as "Net monetary inflation adjustment income (loss)" in the income
statement for each period in question. See Notes 2 and 24 to the Consolidated
Financial Statements.
 
INCOME TAX MATTERS
 
  Consolidated income tax returns are not permitted in Colombia. The effective
statutory income tax rate for the Company was 35% for 1995, 1996 and 1997.
Taxable income is presumed to be not less than the greater of 5% (4% in 1994
and 1995) of shareholders' equity for tax purposes at the end of the
immediately preceding year or 1.5% of gross assets for tax purposes at the end
of the immediate preceding year. Adjustments to income to account for
inflation are taken into account for income tax purposes.
 
  In accordance with Law 142 of 1994 and Law 223 of 1995, entities which
render basic residential telephony services and which are mixed capital
companies (i.e., companies with both public and private capital such as the
Company's subsidiaries) were exempt in 1995 and are partially exempt from the
payment of income taxes for a term of seven years from 1996 with respect to
profits which are retained for upgrade, expansion or replacement of telephone
systems. These companies are exempt from taxes on 100% of income related to
basic telephony services for 1995 and 1996; thereafter the exemption reduces
by 10 percentage points each taxable year through 2000 and then reduces by 20
percentage points in 2001 and 2002. After 2002, there is no exemption.
 
  In July 1997, Law 383 of 1997 established that dividends declared from
companies similar to Transtel's subsidiaries and paid to government entities
are not taxable. As there is not a similar exclusion for private investors
such as Transtel S.A., the Company expects that future dividends declared to
Transtel S.A. will be taxable to it.

RECONCILIATION TO U.S. GAAP
 
  The Consolidated Financial Statements are prepared in accordance with
Colombian GAAP, which differ from U.S. GAAP in certain significant respects. A
comparison of the Company's net income (loss) and shareholders' equity
(deficit) at and for the years ended December 31, 1995 and 1996, and at and
for the nine months ended September 30, 1997, under Colombian GAAP and after
reflecting the material adjustments which arise when U.S. GAAP is applied
instead of Colombian GAAP, is shown below:

                                   BUSINESS
 
THE COMPANY
 
  The Company is the largest private telephone company in Colombia, providing
telephone services to both business and residential subscribers. The Company
(excluding TeleGirardot) currently owns and operates telephone systems serving
seven cities, with an aggregate population of approximately 2.9 million
people, located in the southwestern region of Colombia. As of December 31,
1997, such system provided service to an aggregate of approximately 101,500
subscribers and had an average penetration of approximately 18 lines per 100
people.
 
  On December 31, 1997, the Company acquired TeleGirardot. The statistical,
financial and other data in this Prospectus does not include information
regarding TeleGirardot except where specifically indicated. For information
regarding TeleGirardot see "Prospectus Summary--Recent Developments" herein.
 
  In 1990 through the enactment of Decree 1900, Colombia's government
initiated the deregulation and privatization of the state-owned
telecommunications sector in order to promote competition and encourage
private investment and thereby improve service for its citizens. This was
followed by the enactment of Law 142, which established the basic guidelines
and regulations to support the sector's privatization. Prior to the enactment
of Decree 1900, telephone service in Colombia had been provided by the same
government-owned entities that also provided other basic utility services.
Since most of these municipal entities lacked sufficient capital, spending for
basic utility services such as power and water often took precedence over the
delivery of telephone service. As a result, many of these municipal service
providers have failed to install sufficient capacity to satisfy their
customers' demand for telephone service. For those customers who do currently
receive telephone service through municipal service providers, the municipal
entities provide low-quality service and offer few, if any, of the more
commonly available value-added services.
 
  The Company was formed in August 1993 by certain members of the Caicedo
family, a prominent Colombian family, and Guillermo Lopez, the Company's
President and a Director, to take advantage of the opportunities created by
deregulation. Management's goal is to capitalize on the substantial demand for
telephone service which the Company believes exists throughout Colombia. This
belief is supported by the fact that Colombia's first and third largest
cities, Bogota and Medellin, respectively, where capital has been spent to
meet telephone demand, have recently achieved penetration in excess of 30
lines per 100 people, which is substantially higher than cities in the
Company's service area. The Company seeks to modernize and expand its
telephone systems to accommodate existing demand for telephone service and
future growth.
 
  The Company's objective is to increase the penetration in each of its
markets and to provide high quality value-added telephone services to its
subscribers. For example, in May 1995, the Company, in conjunction with the
local municipality, acquired its first telephone system, the only system
serving the city of Palmira. At the time of the acquisition, this system had
approximately 15,600 subscribers, representing a penetration of approximately
4.9 lines per 100 people. Following the acquisition, the Company initiated its
Expansion Plan in Palmira, which consists of investing approximately $34.2
million to replace a portion of the existing Palmira system's infrastructure,
to upgrade the system with modern equipment from Siemens and to increase
system capacity to 60,000 lines, which implies a penetration of 18.9 lines per
100 people. The Company began offering telephone service in Palmira in
September 1995 and, as a result of the substantial demand, experienced
immediate and significant improvements in operating and financial results.
Under the Company's management, the Palmira system's subscriber base has grown
by 220%, increasing from approximately 15,600 at the time of acquisition to
approximately 50,100 at December 31, 1997. Subsequent to the acquisition of
TelePalmira, the Company acquired three additional operating companies,
increasing its number of subscribers from approximately 15,600 as of September
30, 1995 to approximately 101,500 as of December 31, 1997. In addition to the
subscribers with installed lines as of December 31, 1997, the Company had
20,966 additional customers who have signed promissory notes for new lines to
be installed.

OPERATING COMPANIES--GENERAL
 
  The Company has acquired interests in existing wireline telephone systems
serving the cities of Palmira, Cartago, Popayan, Buga and their surrounding
areas, and built new systems serving the cities of Cali, Yumbo and Jamundi and
their surrounding areas. In each case the Company has joined with the local
municipality to form an Operating Company to own and operate the telephone
system. The Operating Companies are (i) TelePalmira, which services the cities
of Palmira and Candelaria, (ii) TeleCartago, which services the city of
Cartago, (iii) Caucatel, which services the western section of city of
Popayan, (iv) TeleJamundi, which services the city of Jamundi, (v) Bugatel,
which services the city of Buga and its surrounding regions, and (vi) Unitel,
which operates Unitel Wireline in the city of Yumbo, a city adjacent to Cali,
and which, through Unitel Wireless, began servicing the city of Cali in
January 1998.
 
  The existing shareholders of the Company have invested approximately Ps37.4
billion ($30.0 million) of equity in the Company. Approximately Ps27.2 billion
($21.8 million) of this amount has been used to repay local bank borrowings
that were used to finance start up expenses and a portion of the acquisition
costs of the Operating Companies.
 
  The following table provides information regarding the Operating Companies:

EXPANSION PLAN
 
  At the time of acquisition, the Company's systems generally lacked sufficient
capacity to service the demand of their customers in the respective
municipalities and utilized antiquated technology to provide limited service to
their customers. Based on extensive market demand studies, the Company created
the Expansion Plan which is designed to satisfy the significant demand for
telephone lines in each of its operating cities. The Expansion Plan does not
include TeleGirardot, for which a separate expansion plan has been developed.
Management intends to increase the number of installed lines in its seven
operating cities from an aggregate of 56,800 which serve 50,900 subscribers at
the date of acquisition of each of its systems, to approximately 222,200 lines
and subscribers upon completion of the build-out of the Expansion Plan by
December 31, 1998. The Expansion Plan also involves the upgrade of each of its
telephone networks to state-of-the-art digital and fiber-optic technology.
 
  The Company has entered into agreements and letters of intent with Siemens
for the purchase of most of the telephone equipment required for the Expansion
Plan and for the installation of the equipment to be provided to the Company
pursuant to fixed price turn-key construction contracts. In addition, the
Company has entered into an agreement with IBM de Colombia S.A. (an affiliate
of IBM) for the purchase and installation of hardware and software that will be
used to offer value-added services for its telephone systems which, together
with the equipment provided by Siemens, comprises most of the equipment
necessary to complete the Expansion Plan. As of February 28, 1998, the Company,
in conjunction with Siemens, had completed the installation of approximately
105,100 new lines, or approximately 64%, of the Company's Expansion Plan.
 
  The Expansion Plan is projected to require aggregate capital expenditures of
approximately $181.8 million, approximately 70.0% of which will be incurred
pursuant to fixed price equipment purchase agreements (or letters of intent)
and turn-key installation contracts. As of September 30, 1997, approximately
$7.8 million was financed with local bank borrowings, all of which was repaid
with a portion of the proceeds of the Offering, and approximately $1.5 million
was financed with cash flow from operations. The remainder of the Expansion
Plan, approximately $172.5 million, has been or will be financed with (i)
approximately $41.0 million of the proceeds of the Offering; (ii) approximately
$102.7 million of Vendor Financing (see "Risk Factors--Contingency of Vendor
Financing"); (iii) the sale of investments of $5.7 million; and (iv)
approximately $23.1 million of DIAN Financing (see "Description of Existing
Indebtedness--DIAN Financing"). See "Use of Proceeds." As of February 28, 1998,
the Company had incurred approximately $118.2 million of capital expenditures
relating to the Expansion Plan and expects to incur the remainder,
approximately $63.6 million, by the end of 1998.
 
  As of February 28, 1998, approximately Ps15.0 billion ($12 million) of
capital expenditures has been incurred relating to the Expansion Plan for
Bugatel, Ps14.3 billion ($11.5 million) for Caucatel, Ps33.9 billion ($27.2
million) for TelePalmira, Ps10.7 billion ($8.6 million) for TeleJamundi, Ps8.7
billion ($7.0 million) for Unitel Wireline, Ps7.7 billion ($38.3 million) for
Unitel Wireless, and Ps16.9 billion ($13.6 million) for TeleCartago. The
Company expects to incur approximately $4.0 million under the TeleGirardot
Expansion Plan which will be financed with cash flow from its operations.
 
  For the Company's expansion plan with respect to TeleGirardot, see
"Prospectus Summary--Recent Developments."
 
BUSINESS AND GROWTH STRATEGY
 
  The Company's objective is to become the leading provider of quality
telephone services in each city in which it operates. The Company's business
and growth strategy includes the following:
 
  . Capitalize on Significant Demand for Telephony Services. The Company
    believes that the low telephone penetration levels throughout Colombia,
    in general, and the southwestern region in particular, provide a
    substantial opportunity to quickly increase subscribers, net income and
    EBITDA in its markets. In the aggregate, the Expansion Plan assumes that
    the Company increases penetration of its markets from approximately 16.9
    lines per 100 people at the time of acquisition to 22.8 lines per 100
    people upon
 
                                       57
<PAGE>
 
   completion of the Expansion Plan. Management expects similar penetration
   increases with respect to the TeleGirardot Expansion Plan. Management
   believes that these penetration levels are achievable, especially when
   compared to two of Colombia's largest cities, Bogota and Medellin, where
   substantial capital has already been spent to expand and modernize the
   telephone systems and where penetration levels are currently in excess of
   30 lines per 100 people. Furthermore, after operating in Palmira for only
   28 months, the Company has added more than 34,400 subscribers, which
   represents an increase in telephone penetration from 4.9 lines per 100
   people to approximately 18 lines per 100 people at December 31, 1997.
 
  . Create Strategic Alliances with Municipalities. The Company seeks to
    maintain a strong relationship with each of the municipalities in which
    it operates. This is accomplished primarily by establishing a mixed
    capital company in which both the Company and the municipality are
    investors. This structure allows the municipality to enjoy the benefits
    of privatization while maintaining an ongoing economic interest in these
    telephone operations. At the same time, the Company realizes substantial
    benefits from working together with the municipal government, including:
    (i) access to extensive demographic information which allows the Company
    to optimize its network build out; (ii) work permits and rights of way to
    ensure that the build out plan is completed quickly and efficiently; and
    (iii) access to public records regarding non-paying customers of the
    local government's other utility services. In addition, in situations
    where the Company has acquired existing telephone systems, management has
    the opportunity to retain the qualified employees of those systems.
 
  . Utilize International Expertise. Since its inception, the Company has
    contracted for the support of various internationally recognized
    consultants to complement its own expertise. Prior to entering a new
    market, management completes a full market demand study and in certain
    instances has relied on the services of independent research consultants,
    to gather and assess projected levels of demand as well as other
    demographic and competitive information. The Company then sizes and
    designs its networks around these demand parameters. Commonwealth
    Communications, Inc. advised the Company with respect to the selection of
    equipment manufacturers and the design of the Palmira, Jamundi and Yumbo
    wireline telephone systems, and Bellcore advised the Company with respect
    to the selection of equipment and design of the Unitel Wireless system in
    Cali. Pursuant to the Expansion Plan and the TeleGirardot Expansion Plan,
    the Company will rely on Siemens for the supply of equipment for both its
    wireline and wireless networks as well as the design, construction and
    installation of most of its systems pursuant to fixed price, turn-key
    contracts. In addition, the Company has contracted with IBM to install
    Internet-related services. The Company has also contracted C-NIX, a
    leading international information operating systems provider, to upgrade
    its existing facilities and enhance the interface between its management
    control and information systems. Management believes that the Company has
    realized substantial benefits from these telecommunication services and
    expects to continue to utilize the expertise of these organizations.
 
  . Install Modern Telephony Equipment. The Company seeks to install high-
    capacity, modern telephony equipment with sufficient capacity to meet
    each market's expected demand. In the case of its wireline networks, the
    Company, in conjunction with its primary equipment vendor, Siemens, has
    installed a fiber-optic trunk supported by fully digital local exchanges.
    In the case of its wireless networks, the Company is installing a fixed
    wireless system utilizing DECT equipment provided by Siemens. This modern
    technology allows the Company to offer its subscribers a full range of
    traditional and non-traditional value-added services, including call
    waiting, voice mail, Internet access, ISDN and Centrex.
 
  . Maximize Revenue Generation. The Company seeks to maximize the revenue
    generated from each installed line by capitalizing on its efficient
    operating structure and by offering subscribers a full range of telephony
    services. One of the stated goals of the recent deregulation of the local
    telephone markets by the Colombian government is to promote competition
    among public and private operators on the basis of efficiency and
    customer service, rather than price. The government accomplished this by
    requiring operators to set tariffs, at their option, based on either (i)
    their or their predecessor's costs or (ii) their competitors' costs, but
    in no event below the cost of providing service. This law has benefited
    the Company by allowing management to set tariffs at levels established
    by inefficient municipal operators,
 
                                      58
<PAGE>
 
   rather than the Company's own lower cost of operation. This pricing
   structure allows the Company to realize a high return on its capital
   investment, especially when compared to its inefficient municipal
   competitors. The Company's operating results are further enhanced by the
   new, value-added telephony services that the Company offers as a result of
   its system upgrades which are not currently provided by its municipal
   competitors.
 
  . Provide Excellent Customer Service. Telephone subscribers in Colombia
    have historically received poor quality service. For example, under the
    management of the municipality, in September 1995, Palmira customers were
    able to complete approximately 40% of their calls and an estimated 17% of
    subscribers experienced breakdowns which lasted an average of more than
    12 hours. The Company utilizes sophisticated computer hardware and
    software to manage, administer and correct telephone problems in its
    telephone systems. This has resulted in a dramatic improvement in the
    operating performance of its systems. In Palmira, in December 1997, the
    Company's subscribers completed approximately 67% of their calls and only
    5.7% of subscribers experienced breakdowns lasting only approximately 6
    hours. In addition, the Company operates customer service centers in each
    of the Company's markets and utilizes an aggregate of approximately 40
    dedicated employees for this purpose.
 
  . Pursue Selective Acquisitions and Other Business Opportunities. The
    Company intends to selectively pursue acquisitions of additional
    telephone networks from municipalities in Colombia engaged in
    privatizations. The Company anticipates making bids for one or more
    municipal systems in the upcoming months, including systems within and
    beyond the southwestern region of Colombia. Management expects that any
    future acquisitions will be structured similarly to its existing
    acquisitions, including a substantial investment and ownership by the
    municipality involved. The Company anticipates pursuing only those
    markets which have low penetration levels and indications of significant
    unmet demand for telephony service. In addition, the Company expects to
    capitalize on the recent deregulation of the long distance market by
    aligning itself with a strategic international partner.
 
DESCRIPTION OF THE OPERATING COMPANIES
 
TELEPALMIRA
 
 Overview
 
  TelePalmira services the municipalities of Palmira and Candelaria. Palmira is
located 15 kilometers from Cali. Palmira's population is approximately 254,700
people and is distributed among several socioeconomic levels, with a majority
of the population belonging to the middle income bracket of Colombia. Palmira
has a stable economic base which includes agriculture, agribusiness, light
manufacturing, transportation and business commerce. The area surrounding
Palmira produces sugar cane, coffee, rice, corn and other agriculture products
used as raw material in the industries of Palmira and Yumbo. In addition,
Palmira has an international airport with significant air freight operations
and facilities. Candelaria is a municipality adjacent to Palmira with a
population of approximately 63,300 people. Candelaria is an important
residential center for the workers of the labor intensive sugarcane industry.
 
 Customers and Competition
 
  In 1997, TelePalmira's subscriber base was composed of approximately 83%
residential and 17% commercial subscribers. The Company believes that, through
its technology, it can offer custom-made solutions to the business needs of its
commercial subscribers, such as Centrex, ISDN, DID and high speed access
through fiber optics. As a result, the Company expects that it can increase
both usage by commercial subscribers and the number of lines per subscriber.
The Company also believes that it can increase its residential subscriber base
through its sales and marketing efforts and by encouraging Internet, facsimile
and other data applications in the home.
 
  TelePalmira has no current competition in Palmira or Candelaria.
 
                                       59
<PAGE>
 
 History
 
  Prior to September 1, 1995, when TelePalmira began commercial operations,
telephone service for Palmira had been provided by Empresas Publicas
Municipales de Palmira, a public entity owned by the municipality of Palmira.
The telephone services provided at that time were generally below standard,
with substantial unmet demand. On May 31, 1995, Transtel and the municipality
of Palmira incorporated TelePalmira to provide telephony services in the cities
of Palmira and Candelaria. Transtel contributed approximately Ps13.4 billion
($10.8 million) in cash and the municipality of Palmira contributed certain of
its existing telecommunications assets and infrastructure valued at
approximately Ps8.9 billion ($7.1 million) to the capital of TelePalmira. In
return for these contributions, Transtel received 60% of TelePalmira's shares
and the municipality of Palmira received 40% of TelePalmira's shares.
 
 Expansion Plan and Growth Strategy
 
  The portion of the Expansion Plan relating to TelePalmira is substantially
completed. The Expansion Plan involved the design, construction, installation
and operation of a local telephone network with a capacity of 60,000 lines, of
which 50,500 have been installed as of December 31, 1997, representing a 76.5%
completion of the network installation. An implied penetration of 18.9 lines
per 100 people is expected upon completion of the Expansion Plan. The newly
installed system consists of an advanced network utilizing digital switching
and fiber-optic transmission technology. The new lines are supported by a
digital host installed in TelePalmira's Central Office and three digital remote
switches installed in newly constructed buildings. The estimated cost of
TelePalmira's completed Expansion Plan is approximately $34.2 million. This has
been financed with proceeds from certain Vendor Financing, debt obtained from
local financing institutions repaid with proceeds of the Offering, proceeds
from the Offering and the DIAN Financing.
 
  TelePalmira's growth strategy is to provide the most advanced
telecommunications service in Palmira and Candelaria while improving the
percentage of calls completed and reducing the number of service calls and
breakdowns. The Expansion Plan has resulted in an increase in penetration for
TelePalmira from 4.9 lines per 100 people at September 1, 1995 to 15.7 lines
per 100 people at December 31, 1997. TelePalmira's growth strategy involves:
(i) increasing the number of lines available; (ii) actively marketing to new
subscribers; and (iii) offering high quality service to a substantial portion
of the population for whom telephony services were previously unavailable.
 
 Results of Operations
 
  At the time of the acquisition, Palmira had approximately 15,600 telephone
subscribers, representing a telephone penetration of approximately 4.9 lines
per 100 people. Following the acquisition, the Company initiated its Expansion
Plan in Palmira, which consists of investing approximately $34.2 million to
replace the existing Palmira system's infrastructure, to upgrade the system
with modern equipment from Siemens and to increase system capacity to
approximately 60,000 lines, which implies a penetration of 18.9 lines per 100
people. The Company began offering telephone service in Palmira in September
1995 and, as a result of the substantial demand, experienced immediate and
significant improvements in operating and financial results. Under the
Company's management, the Palmira system's subscriber base has grown by 220%,
increasing from approximately 15,600 at the time of acquisition to
approximately 50,100 at December 31, 1997. Under the Company's management,
revenues generated by the Palmira system have increased 44% for the nine months
ended September 30, 1997 as compared to the same period in 1996, to Ps9.8
billion ($7.9 million) from Ps6.8 billion ($5.5million). EBITDA decreased 16%
for the nine months ended September 30, 1997 as compared to the same period in
1996 to Ps3.6 billion ($2.9 million) from Ps4.3 billion ($3.5 million). Net
income decreased 41.0% for the nine months ended September 30, 1997 as compared
to the same period in 1996 to Ps1.5 billion (1.2 million) from Ps2.6 billion
($2.1 million).

TELECARTAGO
 
 Overview
 
  TeleCartago services the municipality of Cartago which is located 237
kilometers northeast of Cali and 18 kilometers from Pereira, the capital of
Risaralda, which is a city with a population of approximately 416,100 people.
Cartago's population is approximately 125,900 people and is distributed among
several socioeconomic levels, with a majority of the population belonging to
the middle income bracket of Colombia. Cartago is located within Colombia's
Zona Cafetera (coffee-growing region) and is one of the most important
agricultural centers in the northern Valle del Cauca. Overall, the Zona
Cafetera provides nearly half of the country's coffee production, but covers
only 1.2% of the country's geographic area. Cartago has a stable and diverse
economic base which includes agriculture, agri-business, light manufacturing,
cattle raising and construction. In addition, Cartago has an international
airport with significant air freight operations and facilities.
 
 Customers and Competition
 
  Upon the initiation of the Company's operation of TeleCartago in April 1997,
TeleCartago's subscriber base was composed of approximately 69% residential
and 31% commercial subscribers. The Company believes that, through its
technology, it can offer custom-made solutions to the business needs of its
commercial subscribers, such as Centrex, ISDN, DID and high speed access
through fiber optics. As a result, the Company expects that it can increase
both usage by commercial subscribers and the number of lines per subscriber.
The Company also believes that it can increase its residential subscriber base
through its sales and marketing efforts and by encouraging Internet, facsimile
and other data applications.
 
  TeleCartago's only competition in Cartago is Empresa Regional de
Telecomunicaciones ("ERT"), a telephone service provider owned by the
Departamento of Valle del Cauca. ERT commenced operations in Cartago in 1995
and the Company estimates that ERT currently has 10,000 subscribers.

 History
 
  Prior to April 1, 1997, when TeleCartago began commercial operations,
telephone service for Cartago had been provided by both Empresas Publicas
Municipales de Cartago, a public entity owned by the municipality of Cartago,
and ERT. The telephone service provided at that time was generally below
standard, with substantial unmet demand for telephone services. On January 3,
1997, Transtel and the municipality of Cartago incorporated TeleCartago to
provide telephony services in the city of Cartago. Transtel contributed
approximately Ps4.3 billion ($3.5 million) in cash and the municipality of
Cartago contributed certain of its existing telecommunications assets and
infrastructure valued at approximately Ps2.3 billion ($1.9 million) to the
capital of TeleCartago. In return for these contributions, Transtel received
65% of TeleCartago's shares and the municipality of Cartago received 35% of
TeleCartago's shares.
 
 Expansion Plan and Growth Strategy
 
  TeleCartago's Expansion Plan consists of upgrading the central exchanges and
the 14,100 existing lines acquired from the municipality and expanding the
network. Once completed, the telephone network system will consist of an
advanced network utilizing digital switching and fiber-optic transmission
technology. The new lines will be supported by a digital host installed in
Cartago's Central Office and three digital remote switches installed in newly
constructed buildings. The estimated cost of TeleCartago's completed Expansion
Plan is approximately $18.3 million, to be financed with proceeds from Vendor
Financing, debt obtained from local financing institutions (and repaid with
the proceeds of the Offering), proceeds from the Offering and the DIAN
Financing. Following completion of the Expansion Plan, TeleCartago will have
approximately 25,100 lines and an implied penetration of 27.9 lines per 100
people. As of December 31, 1997, TeleCartago had installed 17,600 lines
(including new installed lines and switching upgrades) since acquisition,
resulting in an installed base of approximately 21,100 lines.
 
  TeleCartago's growth strategy is to provide the most advanced
telecommunications service in Cartago and the surrounding regions. TeleCartago
plans to increase its penetration rate in Cartago by: (i) increasing the
number of lines available; (ii) actively marketing to new subscribers; and
(iii) offering high quality service to a substantial portion of the population
for whom telephony services were previously unavailable.
 
CAUCATEL
 
 Overview
 
  Popayan, the capital of the Departamento of Cauca, is located 189 kilometers
south of Cali. The city is the capital of the Departamento of Cauca and houses
several universities and various museums, churches and monasteries. Popayan's
population is approximately 212,800 people, of which approximately 76,600
people live in the western section of the city, where Caucatel operates.
Popayan's population is distributed among several socioeconomic levels, with a
majority of the population belonging to the middle income bracket of Colombia.
Popayan's economic base includes agriculture, agribusiness, light
manufacturing, cattle raising, mining and tourism.
 
 Customers and Competition
 
  Upon the initiation of Transtel's operation of Caucatel in May 1997,
Caucatel's subscriber base was composed of approximately 93% residential and
7% commercial subscribers. The Company believes that it can increase usage in
Popayan by offering Internet and other data application services to the
student population attending Popayan's universities. In addition, the
universities serve as a prime training center for potential employees of
Caucatel and the Company. Furthermore, as a result of Popayan's geographic
location within the region and its status as the capital of the Departamento
of Cauca, Popayan has significant commercial and trading activity. Therefore,
Caucatel will focus its marketing efforts on these potential commercial
subscribers.
 
  Caucatel has no competitors in the western region of Popayan. Caucatel
services the western region of Popayan only. The eastern region is serviced by
Empresa Municipal de Telecomunicaciones de Popayan
 
                                      62
<PAGE>
 
("EMTEL"), a municipally owned company which had approximately 8,500
subscribers as of December 31, 1997.
 
 History
 
  Prior to May 1, 1997, when Caucatel began commercial operations, telephone
service for Popayan had been provided by EMTEL, the municipally owned service
provider. Subsequently, EMTEL decided to split its operations into eastern and
western service areas and offered its western operations for sale. On April
30, 1997, Transtel and the municipality of Popayan incorporated Caucatel to
provide telephony services in the western section of the city of Popayan.
Transtel contributed to Caucatel approximately Ps1.0 billion ($851,000) in
cash and contributed assets valued at approximately Ps6.9 billion ($5.6
million) and the municipality of Popayan contributed its existing
telecommunications network and infrastructure valued at approximately Ps7.7
billion ($6.2 million) to the capital of Caucatel. In return for these
contributions Transtel received 51% of Caucatel's shares and the municipality
of Popayan received 49% of Caucatel's shares.
 
 Expansion Plan and Growth Strategy
 
  Caucatel's Expansion Plan was completed by December 31, 1997. As of December
31, 1997, Caucatel had a total of approximately 23,000 digital lines
(including approximately 3,400 newly installed digital lines and approximately
19,600 lines upgraded from analog to digital) and an implied penetration of
30.0 lines per 100 people. The telephone system consists of an advanced
network utilizing digital switching and fiber-optic transmission technology.
The new lines are supported by a digital host and various digital remote
switches. The cost of Caucatel's Expansion Plan is approximately $11.5
million, financed with proceeds from Vendor Financing, debt obtained from
local financing institutions (and repaid with the proceeds of the Offering),
proceeds from the Offering and the DIAN Financing. Following completion of the
Expansion Plan, Caucatel will have approximately 23,000 lines and an implied
penetration of 30.0 lines per 100 people.
 
  Caucatel's growth strategy is to provide the most advanced
telecommunications service in the western section of Popayan and the
surrounding regions. Caucatel plans to increase its penetration rate in
Popayan by: (i) increasing the number of lines available; (ii) actively
marketing to new subscribers; (iii) offering high quality service to a
substantial portion of the population for whom telephony services were
previously unavailable; and (iv) providing value-added services including
voice mail, Internet services and videoconference calling.
 
TELEJAMUNDI
 
 Overview
 
  TeleJamundi services the municipality of Jamundi, which is located 23
kilometers south of Cali. Jamundi's population is approximately 59,100 people.
Jamundi is currently undergoing growth of its population that is primarily
driven by the relocation of middle and upper-middle income people from Cali to
suburban locations such as Jamundi. This has resulted in the construction of
two major malls, institutional and recreational facilities, and residential
developments in Jamundi.
 
 Customer Base and Competition
 
  TeleJamundi expects its subscriber base to be composed of 93% residential
and 7% commercial subscribers. As a result of EMCALI's limited telephone
service, Jamundi has very low installed lines and penetration rates. As of
December 31, 1997, the municipality of Jamundi had approximately 11,000
installed lines and a penetration of 27.4 lines per 100 people.
 
  EMCALI continues to provide telephone service in Jamundi and is
TeleJamundi's only competitor in the municipality.
 
                                      63
<PAGE>
 
 History
 
  Prior to June 27, 1997, when TeleJamundi began commercial operations,
telephone service for Jamundi had been provided exclusively by EMCALI. The
telephone services provided at that time were generally below standard, with
substantial unmet demand for telephone services. On September 29, 1993,
Transtel and the municipality of Jamundi incorporated TeleJamundi to provide
telephony services in the city of Jamundi. Transtel contributed approximately
Ps24.4 million ($19,600) in cash and the municipality of Jamundi contributed
demographic information, the necessary civil work permits and approximately
Ps10.5 million ($8,400) in cash to the capital of TeleJamundi. In return for
these contributions, Transtel received 70% of TeleJamundi's shares and the
municipality of Jamundi received 30% of TeleJamundi's shares.
 
  At December 31, 1997, TeleJamundi was indebted to the Company for
approximately Ps12 billion ($9.6 million). The Company is negotiating with the
municipal shareholder of TeleJamundi with respect to the potential
recapitalization of TeleJamundi by cancellation of such indebtedness in
exchange for approximately Ps4.0 billion ($3.7 million) of shares of
TeleJamundi, the number of such shares to be determined by shareholder
approval of a valuation of the Company.
 
 Expansion Plan and Growth Strategy
 
  TeleJamundi's Expansion Plan is currently underway and involves the design,
construction, installation and operation of a local telephone network with a
capacity of 15,000 lines, of which 11,000 lines were installed as of December
31, 1997. The newly installed system consists of an advanced network utilizing
digital switching and fiber-optic transmission technology. The new lines are
supported by a digital host and various digital remote switches. The estimated
cost of TeleJamundi's Expansion Plan is approximately $11.2 million, to be
financed with proceeds from Vendor Financing, debt obtained from local
financing institutions (and repaid with the proceeds of the Offering),
proceeds from the Offering and the DIAN Financing. Following completion of the
Expansion Plan, TeleJamundi will have approximately 15,000 lines and an
implied penetration of 34.2 lines per 100 people.
 
  TeleJamundi's growth strategy is to provide the most advanced
telecommunications service in Jamundi. TeleJamundi expects to increase its
penetration rate by: (i) increasing the number of lines available; (ii)
actively marketing to new subscribers; (iii) offering high quality service to
a substantial portion of the population for whom telephony services were
previously unavailable; (iv) targeting EMCALI's subscribers to switch to the
Company's service; and (v) providing value-added services.
 
BUGATEL
 
 Overview
 
  The town of Buga is located in the heart of the Valle del Cauca, 97
kilometers northeast of Cali. Buga's surrounding regions boast prime fertile
farmlands typical of the Valle del Cauca. As with other cities in the Valle
del Cauca, Buga's stable economic base is derived largely from agriculture,
agribusiness and cattle raising and farming. Due to various historical
incidents, Buga is also the focus of religious tourism which streams to the
city steadily throughout the year giving rise to small commercial and lodging
businesses. Buga, together with its surrounding regions, has a population of
approximately 337,400 people. The demographic structure of Buga consists
primarily of middle income households.
 
 Customers and Competition
 
  Upon the initiation of the Company's operation of Bugatel in July 1997,
Bugatel's subscriber base was composed of approximately 66% residential and
34% industrial and commercial subscribers. The Company believes that, through
its technology, it can offer custom-made solutions to the business needs of
its commercial subscribers, such as Centrex, ISDN, DID and high speed access
through fiber optics. As a result, the Company expects that it can increase
both usage by commercial subscribers and the number of lines per subscriber.
The Company also believes that it can increase its residential subscriber base
through its sales and marketing efforts
 
                                      64
<PAGE>
 
and by encouraging Internet, facsimile and other data applications.
Furthermore, the municipality is developing a "dry port" facility. The Company
intends to focus its marketing efforts on these potential customers.
 
  ERT, a telephone service provider owned by the Departamento of Valle del
Cauca, also operates in Buga and is Bugatel's only competitor in the
municipality. TELECOM and Teletulua compete with Bugatel in the surrounding
region of Buga. The Company estimates that, as of December 31, 1997, its
competitors had an aggregate of 30,700 lines.
 
 History
 
  Prior to July 1, 1997, when Bugatel began commercial operations, telephone
service for Buga had been provided by both Empresas Municipales de Buga, a
public entity owned by the municipality of Buga, and ERT. The telephone
services provided at that time were generally below standard, with substantial
unmet demand for telephone services. On June 16, 1997, Transtel and the
municipality of Buga incorporated Bugatel to provide telephony services in the
city of Buga. Transtel initially contributed Ps2.1 billion ($1.7 million) and
in July 1997, contributed an additional Ps4.1 billion ($3.3 million) for a
total of approximately Ps6.2 billion ($5.0 million) in cash. The municipality
of Buga contributed certain of its existing telecommunications network and
infrastructure valued at approximately Ps4.1 billion ($3.3 million) to the
capital of Bugatel. In return for these contributions, Transtel received 60%
of Bugatel's shares and the municipality of Buga received 40% of Bugatel's
shares.
 
 Expansion Plan and Growth Strategy
 
  Bugatel's Expansion Plan consists of upgrading central exchanges and
approximately 11,200 existing lines acquired from the municipality and
installing 9,900 additional lines in the city of Buga and 4,000 wireless lines
in the surrounding rural areas, for a total of approximately 25,100 installed
lines by December 31, 1998. Once completed, the telephone network system will
consist of an advanced network utilizing digital and fiber-optic transmission
technology. The new lines will be supported by a digital host and various
digital remote switches. As of December 31, 1997, Bugatel had a total of
approximately 21,600 digital lines (including approximately 17,800 newly
installed digital lines and approximately 3,800 lines upgraded from analog to
digital). The estimated cost of Bugatel's Expansion Plan is approximately
$16.7 million, to be financed with proceeds from Vendor Financing, debt
obtained from local financing institutions (and repaid with the proceeds of
the Offering), proceeds from the Offering and the DIAN Financing. Following
the completion of the Expansion Plan, Bugatel will have approximately 25,100
lines and an implied penetration of 16.5 lines per 100 people. As of December
31, 1997 Bugatel had a penetration of 12.0 lines per 100 people.
 
  The Company's growth strategy is to provide the most advanced
telecommunications service in Buga and the surrounding regions. Bugatel
expects to increase its penetration rate by: (i) increasing the number of
lines available; (ii) actively marketing to new subscribers; (iii) offering
high quality service to a substantial portion of the population for whom
telephony services were previously unavailable; (iv) targeting ERT's
subscribers to switch to the Company's service; and (v) providing value-added
services.

 Customers and Competition
 
  Unitel expects that its subscriber base will be composed of 44% residential
and 56% commercial subscribers. Unitel also expects that its commercial
subscriber base will generate higher revenues per subscriber than any other
Operating Company. In addition, the Company expects to offer commercial
subscribers in Yumbo specialized equipment, such as PBX and direct fiber optic
cable. Historically, the municipality of Yumbo has been served by analog
remote switching stations established by EMCALI.
 
  EMCALI provides telephone service in Yumbo and is Unitel's only competitor
in the municipality. The Company estimates that, as of December 31, 1997,
EMCALI had approximately 5,500 installed lines.
 
 History
 
  Prior to June 27, 1997, when Unitel began commercial operations, telephone
service for Yumbo had been provided by EMCALI. The telephone services provided
at that time were generally below standard, with substantial unmet demand. On
March 11, 1994, Transtel and the municipality of Yumbo incorporated Unitel to
provide telephone services in Yumbo. Transtel contributed approximately Ps75.5
million ($60,600) in cash and the municipality of Yumbo contributed
demographic information and approximately Ps18.9 million ($15,100) in cash to
the capital of Unitel. In return for these contributions, Transtel received
80% of Unitel's shares and the municipality of Yumbo received 20% of Unitel's
shares.
 
 Expansion Plan and Growth Strategy
 
  Unitel's Expansion Plan is currently underway and involves the design,
construction, installation and operation of a local telephone network with a
capacity of 15,000 lines, of which approximately 5,250 were installed as of
December 31, 1997. The newly installed system consists of an advanced network
utilizing digital switching and fiber-optic transmission technology. The new
lines are supported by a digital host and various digital remote switches. The
estimated cost of Unitel's completed Expansion Plan in Yumbo is approximately
$16.8 million, to be financed with proceeds from Vendor Financing, debt
obtained from local financial institutions (and repaid with the proceeds of
the Offering), proceeds from the Offering and the DIAN financing. Following
completion of the Expansion Plan, Unitel will have approximately 15,000 lines
and an implied penetration of 28.5 lines per 100 people. As of December 31,
1997, Unitel had a penetration of 13.2 lines per 100 people. Due to its heavy
commercial subscriber base, Unitel will install a network consisting of
maximum band width and capacity. This capacity will also be utilized by the
other Operating Companies for the provision of Internet services, except
Caucatel, which will provide its own Internet service to its subscribers. The
supporting Internet services will be supplied by IBM as part of its pilot
program for its Latin American market development activities.
 
  Unitel's growth strategy in Yumbo focuses on satisfying the needs of its
predominantly commercial subscribers. Unitel plans to increase its penetration
rate by: (i) increasing the number of lines available per subscriber; (ii)
implementing its marketing strategy; (iii) targeting EMCALI's subscribers to
switch to the Company's service; and (iv) providing value-added services.
 
UNITEL WIRELESS
 
 Overview
 
  Cali is the second largest city in Colombia and is located in the
southwestern region of the country. Cali's population is 1,908,600 people.
Cali's population is distributed among all socioeconomic levels, with a
majority of the population belonging to the middle income bracket of Colombia.
Cali has a stable and diverse economic base which includes agriculture,
agribusiness, manufacturing and transportation. As of December 31, 1995,
EMCALI provided telephone service in Cali to approximately 386,800
subscribers, representing a penetration of 20.3 lines per 100 people.

 Expansion Plan and Growth Strategy
 
  As an alternative to the fixed landline services in Cali provided by EMCALI,
Transtel is implementing a fixed wireless system in order to penetrate the
Cali market. This technology is cost effective, can be quickly deployed, and
has a transmission quality that is comparable to wireline systems. See
"Business--Technology." In addition, wireless services do not require the
civil works permits that would be required for a landline system. In September
1996, Telemercadeo was hired by Transtel to conduct a study of telephone
demand in certain sections of the city of Cali. The study estimated that there
was unmet commercial demand in the northern section of Cali for approximately
50,100 additional lines.
 
  Unitel Wireless' Expansion Plan consists of the design, construction,
installation and operation of a fixed wireless system for 59,000 subscribers
in the city of Cali. The new subscribers will be served by Unitel's digital
host. The Company has hired Bellcore to evaluate the wireless technologies
available and to advise the Company with respect to the best application for
this market. Although installation of switching infrastructure and antennas
was substantially completed at Unitel Wireless in the fourth quarter of 1997,
there was an interference from unauthorized radio spectrum users, which was
subsequently removed by the Ministry of Communications. This delayed the
Company's launch of operations at Unitel Wireless until the first quarter of
1998. The estimated cost of Unitel Wireless' Expansion Plan in Cali is
approximately $73.1 million to be financed with proceeds from certain Vendor
Financing, debt obtained from local financing institutions (and repaid with
the proceeds of the Offering), proceeds from the Offering and the DIAN
Financing.
 
  The Company's growth strategy is to provide the most advanced
telecommunications service in Cali. Unitel expects that its subscriber base
will be composed of approximately 50% residential and 50% commercial
subscribers. Unitel subscriber growth began to occur in the last quarter of
1997 and early 1998 after Transtel installed its telecommunications network
and implemented its marketing strategy. Transtel expects to achieve its
objectives in Cali by: (i) offering high quality service; (ii) meeting the
substantial demand that currently exists in Cali; (iii) targeting subscribers
of the municipality-owned competitor to switch to the Company's service; and
(iv) providing value-added services.
 
  At September 30, 1997, Unitel was indebted to the Company for approximately
Ps6.7 billion ($5.4 million). On December 30, 1997, the Company agreed with
the municipal shareholder to cancel such indebtedness in exchange for
approximately Ps5.7 billion ($4.5 million) of shares of Unitel, an additional
15% of ownership.
 
SERVICES
 
  The Company offers telephone services to residential and commercial
subscribers, including local calls and access to national and international
telephone carriers, Internet access and the ability to utilize standard modem
and fax equipment. The Company's basic residential service includes the
ability to activate a second telephone line without the need for a subscriber
premise visit. Residential and business services also include seven day a week
customer service.
 
  The Company's basic telephone services include the following:
 
  Call Divert/Forwarding diverts or forwards incoming calls to another
telephone number. The Company receives revenue for the diverted part of the
telephone call, as well as for the usual incoming call.
 
  Call Barring prevents calls from being completed to specified groups of
numbers, such as "for fee" services and long distance telephone calls.
 
  Caller Display enables subscribers with compatible equipment to identify the
telephone number of incoming calls.
 
 
                                      67
<PAGE>
 
  Caller Return identifies and automatically redials the telephone number from
which the most recent incoming call was placed. The Company receives revenue
from the returned call.
 
  The Company also offers a variety of special telephone services for an
additional fee, including the following:
 
  Call Waiting alerts subscribers who are using their telephone that another
party is attempting to place a call to them; subscribers then have the option
of ignoring the new telephone call or answering it while placing their
existing call on hold. In addition to a subscription charge for call waiting,
the Company receives revenues from the second caller's telephone service
provider for completing a call that, in the absence of the Company's call
waiting feature, would not have been connected.
 
  Three Way Calling enables subscribers to place conference telephone calls
with two additional parties. In addition to the subscription charge for
conference calling, the Company receives revenues from each of the telephone
calls placed to the participating parties.
 
  Voice Mail enables subscribers to receive and retrieve voice mail messages,
whether at home or from an outside location. In addition to the subscription
charge for voice mail, the Company receives revenues from each of the
telephone calls placed to retrieve messages.
 
  Alarm Calls enables subscribers to have telephone calls placed to their
number at a specified time (e.g., wake-up telephone calls or appointment
reminders). The Company receives a fee for each such call.
 
  ISDN (Integrated Services Digital Network) allows two-way, simultaneous
voice and data transmission in digital formats over the same telephone line.
ISDN permits videoconferencing over a single line, for example, and also
supports many value-added networking capabilities, reducing costs for end-
users and resulting in a more efficient use of available facilities.
 
  Internet The Company has entered into an agreement with IBM for the purchase
and installation of Internet hardware and software in each of the Operating
Companies. The Company expects to charge its Internet subscribers a monthly
service fee and a monthly usage fee to access the Internet. All of the
Operating Companies will be able to provide Internet access by May 1, 1998 and
the Company expects to be one of the leading providers of Internet related
services in Colombia. See "Description of Existing Indebtedness--IBM
Arrangement."
 
  The Company intends to continue to develop and introduce additional value-
added services in order to retain its competitive advantage and generate
additional revenues.
 
MARKETING
 
 Overview
 
  The Company's primary marketing objectives are to: (i) create a regional
brand perceived as a reliable, high quality telephone company; (ii) achieve
increased market penetration rates in its operating markets; and (iii) educate
consumers as to the benefits of value-added services.
 
  The Company markets to both residential and commercial subscribers in its
respective operating regions. Each Operating Company develops an in-depth
knowledge of its markets by analyzing the demographic and customer information
provided by its municipal shareholders as well as, in certain cases, the
market studies conducted for the Company by independent consultants. In
addition, the Company conducts its own door-to-door census in each of its
markets. Based on this information, the Company creates a detailed marketing
plan to increase subscribers and their use of services.
 
 
                                      68
<PAGE>
 
 Sales
 
  The Company uses a combination of door-to-door inquiries, selling booths and
networking to offer its services to consumers. Each Operating Company employs
its own trained sales force to contact potential subscribers. As of December
31, 1997, the Company and the Operating Companies (excluding TeleGirardot)
employed a sales staff of 66 people, which is expected to continue to
increase.
 
 Advertising
 
  The Operating Companies use radio, television, newspapers and direct mail to
solicit new subscribers, establish brand awareness, retain subscribers and
stimulate usage. Radio and direct mail are the main methods by which the
Operating Companies advertise because these methods are relatively inexpensive
and offer high-volume coverage. National television and newspaper
advertisements are generally used only to establish the Operating Company's
name in the market when it commences operations and to maintain brand
recognition once the network is operating. The Operating Companies' direct
mail campaigns involve soliciting subscribers through the mail with printed
advertisements describing the telephone service offered. While the Operating
Companies generally have their own database of potential subscribers to whom
they direct their mail campaign, they also have access to the large subscriber
base served by the municipal utilities located in each of their respective
regions.
 
 Customer Service
 
  The Company has focused on providing its subscribers a high level of quality
service by establishing: (i) dedicated customer service centers in each of its
markets; and (ii) a seven-day-a-week customer service telephone hotline.
 
  The Company has customer service representatives who are trained to receive
complaints from subscribers. Subscriber complaints are directly routed to the
engineering department through the Company's internal computer system. The
Company's customer service strategy has resulted in the reduction of customer
service calls and line repair.
 
OPERATIONS
 
 Installation and Maintenance
 
  The installation process for a new subscriber commences with the entry of a
service order into the Company's computerized subscriber administration system
("SAT"). The planning department then verifies that there is sufficient
capacity in the system and assigns a line. Once partial payment of the
connection fee has been received from the subscriber, the SAT system
automatically assigns a work order to an installer. A drop wire, internal
service wire and telephone jack are then installed and tested at the
customer's premises. Any equipment ordered by the customer is also installed.
 
  Maintenance work is begun upon receipt of repair requests from the customer
service center or from the SAT system. Maintenance crews conduct both
preventive maintenance work as well as emergency repairs.
 
 Billing
 
  Transtel generates a monthly bill for each subscriber which itemizes
connection fees and local, cellular and long distance charges. The SAT system
generates all customer billing based on billing information provided by the
Central Office automated message accounting systems.
 
 Credit and Collections
 
  The Operating Companies offer potential subscribers flexible payment plans
of up to 36 months for connection fees and hardware. The subscriber signs a
contract with a partial payment of the connection fee and
 
                                      69
<PAGE>
 
is billed for the remaining balance on a monthly basis depending on the
payment terms agreed upon by the Company and the subscriber. Subscriber
receivables are often converted by the Operating Companies into cash by sale
to local credit institutions. The Operating Companies handle the collection of
the connection fees and any other outstanding payments.
 
  A subscriber is charged interest for its failure to pay fees on time.
Service is suspended for failure to pay for two months and cancelled for
failure to pay for six months. Subscribers are charged substantial
reconnection expenses if their service is cancelled. To date, service
suspensions have not exceeded 1%.
 
  Subscribers can pay their telephone bills at a large number of different
banking institutions in their community.

TECHNOLOGY
 
 Initial Upgrades to Fixed Wireline Systems
 
  Prior to takeover of a newly acquired system, Transtel personnel complete a
full inspection and appraisal of the existing network's elements, operational
procedures and performance parameters. This allows the Company to gather
accurate census, network inventory and subscriber record information which is
used in the network design process. Transtel then establishes new network
priorities and redesigns the network in order to raise it to international
standards. The table below describes certain characteristics of the typical
existing system acquired by Transtel and the Transtel upgrade.

 Transtel's Planned Fixed Wireless System
 
  Transtel is employing a fixed wireless technology from Siemens for both
urban and rural applications. This technology is called DECT. It has its
origins in the wireless PBX technology developed in Europe in the early 1990's
and is based on Time Division Multiple Access ("TDMA") transmission technology
(with reception and transmission slots offset in time).
 
  Transtel selected DECT on the basis of regulatory, market and technical
considerations. Colombia segregates wireless technology into mobile and fixed
categories. Mobile technology (which includes PCS systems) requires operator
licensing and fees whereas fixed technology requires frequency assignment by
the Ministry of Communications. The radio spectrum from 1910-1930 mHz has been
assigned for fixed wireless technology by the Ministry of Communications. DECT
utilizes this frequency and offers digital capabilities. Other systems,
including CDMA and GSM technology, cannot currently be used in Colombia, as
equipment manufacturers have not yet modified their products for use at 1910-
1930 mHz. DECT also offers Transtel the rapid deployment capability it needs
to capture unsatisfied customer demand in target service areas.
 
  DECT provides telecommunications services via antenna sites which may cover
an area of two to ten kilometers in diameter, depending on the density and
usage patterns of subscribers, topography, and existing construction. A
standard cell can cover up to 480 subscribers. Cell size may be modified over
time to accommodate traffic trends. The DECT system utilizes Adaptive
Differential PCM ("ADPCM") technology to compress voice and data
communications and achieve better transmission efficiency.
 
  The basic components of DECT, starting from the subscriber's premises,
consist of a Radio Network Termination Unit ("RNT"), a Radio Base Station
("RBS"), the Radio Base Controller ("RBC") and a Radio Distribution Unit
("RDV").
 
    RNT--Radio Network Termination Unit is a small base station unit
  installed at the subscriber's location next to his telephone allowing for
  two lines to the jack. The RNT accepts any standard telephone, facsimile,
  modem or other telecommunications adjunct. The RNT has its own power
  capability (including an eight-hour battery backup) and connects to an
  antenna installed on the subscriber's roof or other location in "line of
  sight" of the RBS.
 
    RBS--Radio Base Stations are the units with sectorized or omnidirectional
  antennas which receive and transmit to the RNT's, collect all traffic and
  utilize copper cable or coaxial facilities to further aggregate
  communications in the RBC. The RBS is powered remotely and supports up to
  12 channels.
 
    RBC--The Radio Base Controller supports up to 15 RBS interfaces, further
  collects traffic and is linked to the RDU located at the Central Office.
  The link can be either digital microwave, fiber-optic or coaxial cable
  without distance limitations.
 
    RDU--The Radio Distribution Unit is the final link in the chain of nodes
  from the subscriber to the Central Office transporting telephone calls via
  two Megabit channels directly to the switching network. It supports up to
  four RBC interfaces.
 
    There are other elements to the DECT system providing network management
  capabilities, extended coverage and other features essential for a flexible
  network.
 
CONSTRUCTION ARRANGEMENTS
 
  On April 30, 1996, each of TelePalmira, Unitel (with respect to its wireline
applications) and TeleJamundi entered into turn-key arrangements (the "Turn-
Key Arrangements") with Siemens S.A., a Colombian corporation ("Siemens
S.A."), and an affiliate of Siemens, to (i) install the lines, switches and
other equipment leased by each of these Operating Companies from Global under
the Global I Leases (as defined herein), (ii) put in operation such lines and
equipment, (iii) manage the "cut-over" to the new system lines, install air
conditioner equipment and train the personnel who will operate the switching
equipment, (iv) install SDH, (v) expand, replace and install the Outside
Plant, and (vi) complete expansion of the network. The aggregate amount due to
Siemens S.A. under these Turn-Key Arrangements is approximately $8.1 million.
 
                                      72
<PAGE>
 
  For each of the Turn-Key Arrangements described in the paragraph above,
Siemens S.A. has provided the respective Operating Company with performance
bonds equivalent to (i) 10% of the amount of each Turn-Key Arrangement, (ii)
5% of the services contracted under each Turn-Key Arrangement, (iii) 10% of
the cost of the Outside Plant civil works and (iv) up to $100,000 for personal
or property liability.
 
  On June 18, 1997, each of Transtel (in place of Bugatel, which was not yet
formed), TeleCartago and Unitel (with respect to its wireless applications)
entered into Turn-Key Arrangements with Siemens S.A. to (i) install the lines,
switches and other equipment leased by Bugatel, TeleCartago and Unitel from
Global under the Global II Leases (as defined herein), and (ii) put in
operation such lines and equipment. The aggregate amount due to Siemens under
these Turn-Key Arrangements is approximately $6.9 million. Siemens S.A. has
provided Transtel, TeleCartago, and Unitel with performance bonds
substantially similar to those provided to TelePalmira, Unitel and
TeleJamundi. In connection with the negotiations to amend the Global II
Purchase Agreement as set forth in "Description of Existing Indebtedness--
Global-Siemens Arrangements--Global II Purchase Agreement," TeleCartago and
Siemens on February 5, 1998 agreed to reduce the amount due to Siemens under
this Turn-Key Arrangement to approximately $5.3 million.
 
  On May 23, 1997, Transtel entered into a Turn-Key Arrangement with Siemens
S.A. to (i) install the lines, switches and other equipment that Transtel
agreed to contribute to the capital of Caucatel as part of its capital
contribution and which the Company acquired from Siemens pursuant to the
Transtel-Siemens Arrangement, and (ii) put in operation such lines and
equipment. The aggregate amount due to Siemens S.A. under this Turn-Key
Arrangement is approximately $460,000.
 
  The Company is currently negotiating with Siemens S.A. regarding a Turn-Key
Arrangement with respect to the equipment to be provided to the Company
pursuant to the Global III Letters of Intent (as defined herein). The Company
believes that the terms and conditions of this arrangement will be
substantially similar to those contained in the other Turn-Key Arrangements.
 
  The Company is currently negotiating with Siemens regarding contracts for
the supply of equipment to effect the TeleGirardot Expansion Plan.
 
INTERCONNECTION AGREEMENTS
 
 Local Connections
 
  Each Operating Company which has a competitor in its local calling area must
enter into an arrangement with such competitor for access to the competitor's
network so that subscribers can complete local calls between the networks. Law
142 provides that each local service provider must permit each other local
service provider in its local calling area access to its network. Law 142
additionally empowers the CRT to regulate the tariffs associated with such
arrangements. The Company intends to have interconnection agreements between
each of the Operating Companies and their competitors. Interconnection
agreements have been signed between EMCALI and Unitel and between EMCALI and
TeleJamundi. In compliance with Law 142, ERT is interconnected with
TeleCartago and Bugatel and EMTEL is interconnected with Caucatel. However,
there are no written agreements which govern these arrangements.
 
 Long-Distance Connections
 
  Each Operating Company must enter into an interconnection arrangement with
TELECOM for access to the national and international long distance network.
Law 142 provides that TELECOM must permit the Operating Companies to have
access to such network and empowers the CRT to establish the tariff for such
access. At the present time, Unitel and TeleJamundi are provided such access
at the CRT established tariff. The remaining Operating Companies are provided
such access at the rates previously negotiated under expired arrangements
between TELECOM and the former municipal operators of the respective networks.
The Operating Companies, as well as many other local providers in Colombia,
have not entered into formal arrangements with TELECOM as a result of the
impending privatization of national and international long distance service
which will end TELECOM's monopoly and probably lower such tariffs. The
Operating Companies which are operating under expired arrangements expect to
enter into interconnection agreements with either TELECOM at the CRT
established rate, or one of TELECOM's new competitors, if any.

BY-LAWS OF OPERATING COMPANIES
 
  Set forth below is a brief description of certain provisions of the
estatutos sociales (by-laws) (the "by-laws") of each of the Operating
Companies (including TeleGirardot) and Colombian law with regard to each of
the Operating Companies' capital stock. This description does not purport to
be complete and is qualified in its entirety by reference to the by-laws of
each Operating Company.
 
 Capital Stock
 
  The capital stock of each Operating Company is divided into two classes of
common shares, Class A shares and Class B shares, each with par value of one
Peso. Law 142 provides that shares of private public service companies owned
by the Colombian government are referred to as "Class A shares", and shares
owned by private investors are referred to as "Class B shares".
 
 Voting Rights
 
  In accordance with the by-laws of each Operating Company, each Class A share
and Class B share entitles the holder thereof the right to one vote per share
at meetings of the shareholders of such Operating Company.
 
 Preemptive Rights
 
  In accordance with the by-laws of each Operating Company, holders of common
shares of each Operating Company are entitled to preemptive rights in
proportion to their holdings in the event of an issuance of additional shares
by such Operating Company.
 
 Transfer
 
  Under Law Decree 130 of 1976, each shareholder of a mixed capital company
which is a public company has pre-emptive rights with respect to shares
proposed to be sold by a private sector shareholder. These pre-emptive rights
are superior to any pre-emptive rights contained in the by-laws of such
company. Each of the municipalities of Palmira, Cartago and Yumbo have waived
pre-emptive rights. Under Law 226 of 1995, employees, former employees,
unions, pension funds and cooperative entities have pre-emptive rights with
respect to shares of a mixed capital company proposed to be sold by the public
company shareholder. These pre-emptive rights are superior to any pre-emptive
rights contained in the by-laws of such company.
 
  The by-laws of each Operating Company provide that shareholders who wish to
transfer their common shares in an Operating Company must first offer such
shares to the Operating Company. If the Operating Company does not purchase
the shares from the transferor within 30 business days, the Operating Company
is required to offer such shares to the remaining shareholders on a pro rata
basis. Any shares not purchased by the remaining shareholders within the 30
business days following such offer may be offered to third parties, which in
the case of TelePalmira's, TeleCartago's and Unitel's by-laws, must be on
terms no less favorable to the terms offered to the remaining shareholders.
 
 Shareholders' Meetings
 
  The by-laws of each Operating Company provide that shareholders meetings may
be ordinary or extraordinary. Matters that may be considered at an ordinary
meeting are approval of the annual financial statements, distribution of
dividends, election of the members of the Board of Directors, appointment of
administrative officers, and other matters relating to the ordinary course of
the Company's business. Extraordinary meetings may be called at any time to
consider matters beyond the competence of an ordinary meeting, such as
dissolution of an Operating Company.
 
  The quorum required for ordinary and extraordinary meetings of the
shareholders of the Operating Companies consists of two or more shareholders
representing at least 51% of the outstanding shares.
 
                                      74
<PAGE>
 
 Board of Directors
 
  The board of directors of each Operating Company has five members, who are
elected on a cumulative voting basis, and five alternate directors.
 
 Dividends
 
  The distribution of dividends by the Operating Companies is governed by Law
222 of 1995, which requires that any distribution of profits must be taken by
the favorable vote of 78% of the shares represented at a duly convened
shareholders' meeting. If a 78% majority vote cannot be obtained, the Operating
Company is obligated to distribute at least 50% of its liquid profits to the
extent such profits exceed accumulated losses from prior years.
 
LEGAL PROCEEDINGS
 
  Neither the Company nor any of the Operating Companies is currently a
defendant in any legal proceeding.
 
PROPERTIES
 
  On September 18, 1996, Transtel purchased a 2,000 square meter building for
Ps1.7 billion ($1.4 million). See "Certain Related Party Transactions." In
addition, Transtel leases its headquarters at Calle 19N, No 2-29, Oficina 501A,
Cali, Colombia. The monthly payment for such lease is Ps5.4 million ($4,300)
and such lease runs on a year to year basis.
 
  Each Operating Company owns the building where its Central Office is located
and certain smaller properties where some of its remote digital switches are
located. In addition, each Operating Company leases within the municipalities
it serves certain properties which are used for office space or for the
installation of other remote digital switches.
 
EMPLOYEES
 
  As of January 1, 1998, Transtel and its Operating Companies (excluding
TeleGirardot) had approximately 543 employees. As of January 1, 1998, 149 of
those employees were employed by TelePalmira, 71 by Bugatel, 59 by Caucatel, 41
by TeleJamundi, 108 by Unitel, 89 by TeleCartago and 26 by Transtel. Many of
these employees are part of the construction phase of projects that are
currently taking place, and therefore the number of employees will reduce once
these projects are concluded. The Company is not a party to any collective
bargaining agreements and has never experienced a strike or work stoppage. None
of the employees are members of a union. The Company believes its relations
with its employees to be good.
 
                      DESCRIPTION OF EXISTING INDEBTEDNESS
 
GLOBAL-SIEMENS ARRANGEMENTS
 
  Global Telecommunications Operations, Inc. ("Global") is a British Virgin
Islands company owned by the same shareholders who own Transtel. See "Principal
Shareholders." Global was formed in January 1995 for the exclusive purpose of
acting as a financing vehicle for the purchase of telecommunications equipment
from Siemens to be used by the Operating Companies for the development of their
telephone networks. Global has financed, or intends to finance, its purchases
of equipment from Siemens (the "Siemens Financing"). Global then has leased, or
intends to lease, such equipment to an Operating Company pursuant to a lease
agreement (each, a "Global Lease") with terms substantially similar to the
Siemens Financing. Transtel purchased equipment, to be used by Caucatel,
directly from Siemens ($3.3 million for switches and $500,000 for installation)
and contributed such equipment to Caucatel as part of its capital. Caucatel is
the only Operating Company that does not lease its equipment from Siemens. See
Note 26 to the Consolidated Financial Statements and "--Transtel-Siemens
Arrangement." Under the Global Leases, if the Operating Companies are in
default under the Leases, Global has the right to take action against the
assets leased thereunder, including repossession or sale of the assets. See
"Certain Related Party Transactions--Undertakings by Global Regarding
Indebtedness and Line of Business."
 
                                       75
<PAGE>
 
  As a part of the Expansion Plan, Global has entered into two purchase
agreements and two letters of intent with Siemens for the provision of certain
equipment necessary for the Expansion Plan, each as described below (such
purchase agreements and the letters of intent, the "Purchase Agreements").
 
  In consideration for Siemens agreeing to modify certain terms to the
existing Purchase Agreements in connection with the Offering, Global has
assigned to Siemens the lease payments under each of the Global Leases in case
an event of default occurs and is continuing under the Purchase Agreements.
 
  Global I Purchase Agreement. On May 2, 1996, Global entered into a purchase
agreement with Siemens (as amended on July 28, 1997, the "Global I Purchase
Agreement") to purchase certain landline telecommunications equipment to be
used for the development of each of TelePalmira's, TeleJamundi's and Unitel's
respective wireline networks for an aggregate amount of approximately $20.0
million, of which 15% (approximately $3.0 million) was paid upon execution of
the Global I Purchase Agreement. The remaining 85% of the price of equipment
delivered and installed by Siemens under the Global I Purchase Agreement is
payable by Global in 20 semi-annual payments, commencing six months after the
completion of the Turn-Key Arrangements. Global's obligations under the Global
I Purchase Agreement are secured by a pledge of the lease payments under the
Global I Leases (as defined below).
 
  Global I Leases. On August 1, 1996, Global entered into a lease agreement
with each of the following Operating Companies: TelePalmira (the "Global-
TelePalmira Lease"); TeleJamundi (the "Global-TeleJamundi Lease"); and Unitel
(the "Global-Unitel I Lease") (the Global-TelePalmira Lease, Global-
TeleJamundi Lease and Global-Unitel I Lease are collectively referred to as
the "Global I Leases").
 
    Global-TelePalmira Lease. Pursuant to the Global-TelePalmira Lease,
  TelePalmira agreed to pay Global an aggregate amount of approximately $14.4
  million to lease, for a 12-year term, certain switching and cable equipment
  that Global purchased from Siemens under the Global I Purchase Agreement.
  The Global-TelePalmira Lease includes an option to purchase the equipment

              INDUSTRY OVERVIEW; LEGAL AND REGULATORY ENVIRONMENT
 
  Colombia is one of the oldest democracies and most stable economies in Latin
America and is one of only three countries in Latin America rated investment
grade by all three major rating agencies. Colombia has achieved positive real
economic growth every year since 1950 and averaged compounded annual growth in
Gross Domestic Product ("GDP") of approximately 4.7% from 1992 to 1996, one of
the highest growth rates in Latin America. Annual inflation has declined over
the past six years from 26.8% in 1991 to 17.7% in 1997. In recent years, the
Colombian government has encouraged foreign investment and exports through
reduced foreign exchange controls and lower import quotas and tariffs. The
Colombian government has also begun to open certain public services, such as
power and banking, to private sector investment and is considering other
sectors for privatization. In part as a result of these policies, net foreign
investment in Colombia has grown from $3.5 billion in 1990 to $10.5 billion in
1997. During the same period, Colombia has achieved increased diversification
of its export base and the value of its exports has grown from $6.7 billion to
$11.6 billion. See "Risk Factors--Colombian Political, Economic and Social
Risks."
 
  In 1995, Colombia had approximately 4.9 million installed lines,
representing a penetration of approximately 14.0 lines per 100 people which
generated approximately $635 million of revenues representing approximately
44% of the $1.5 billion telecommunications industry. Historically, local
telephony has been treated as a utility. The local telephony network is
fragmented and approximately 30 municipal operators service approximately 780
municipalities. Prior to deregulation, each municipal operator had a monopoly
in the region which it served and typically provided limited and often
marginal service. As a result, Colombia is significantly underserved by
existing wireline operators and demand for telephone service substantially
outweighs supply for telephone lines. This is evidenced by multi-year waiting
lists and unsatisfied demand in Colombia for approximately 1.2 million
telephone lines as estimated by the DNP. The DNP also projects that the
country's existing installed line network will need to more than double by
2007 in order to keep pace with growing demand.
 
  The Colombian government, recognizing the importance of an effective
telecommunications infrastructure and the role that the telecommunications
industry plays in national development, identified the problems in the
telecommunications industry and, from 1990 to 1994, established the regulatory
environment required to support private sector participation. The government
enacted decrees addressing many facets of operation including interconnection,
numbering and tariffs.
 
  In 1990, the Ministry of Communications issued Decree 1900 which permitted
private sector's participation in the state-owned telecommunications industry.
The decree launched a deregulation process which resulted in the privatization
of local wireline telecommunications, the sale of cellular licenses and the
planned privatization of the national long distance carrier, TELECOM. Law 142
established the basic guidelines for the privatization of basic services,
including telecommunications, thereby introducing open competition in the
telecommunications sector and promoting a tariff environment whereby
participants would be encouraged to compete on the basis of efficiency and
service rather than price.
 
  There is currently no restriction in Colombia on competition within the
local telephony business and therefore any person can organize and operate a
telephone company provided such person has obtained the civil works permits
for the construction of the telephone networks from the local municipalities
in the market in which such person operates. Law 142 prohibits a municipality
from denying a company the permit requirements for such works. In addition,
telephone companies are required to enter into interconnection agreements with
the long distance carrier, TELECOM, and other local municipalities for the
provision of national and international long distance services and local
service, respectively. Law 142 requires that this access be granted. See
"Business--Interconnection Agreements--Local Connections" and "Business--
Interconnection Agreements--Long-Distance Connections."
 
  Telephone companies are subject to the supervision of the Superintendencia
de Industria y Comercio (Superintendency of Industry and Commerce), which is
empowered to enforce antitrust regulations, protect free
 
                                      78
<PAGE>
 
competition in the marketplace and protect consumer rights on a case by case
basis, and to the supervision of the Superintendencia de Sociedades
(Superintendency of Corporations), which is entitled by Colombian Commercial
Law to exercise regulatory control over certain activities of
telecommunication service providers. The Superintendencia de Servicios
Publicos (Superintendency of Public Services) ("SPS") was created as a new
organization under Law 142 to review the management and performance of
utilities. Telecommunications service providers are required by Law 142 to
appoint an external professional reviewer to also review their management and
performance. This requirement may be waived by the SPS if it is satisfied that
a company's internal controls are sufficient.
 
  Pursuant to such new regulations, the CRT was created as a special
administrative unit with administrative, technical and financial independence
to oversee the telecommunications sector. The CRT is funded by the companies
it regulates, which are required to pay a fee for this purpose. For 1996, this
fee was set at 0.65% of 1995 operating expenses. The CRT is chaired by the
Minister of Communications, and also includes, as members, the Director of the
DNP and three technical experts appointed by the President of Colombia for
three-year terms. Whereas the SPS is responsible for oversight and control and
has the power to impose sanctions for non-compliance with regulations, the CRT
performs the regulatory functions in the industry such as the establishment of
tariffs for all telecommunication services, which allows operators to set
prices in accordance with costs or at levels established by their competitors.
In addition, the CRT issues regulations for the purpose of promoting
competition, reviews the efficiency of monopolistic service providers, sets
technical standards for telephone services to ensure continuous, quality
service to telephone subscribers, and is also appointed to resolve disputes
among telephone service providers and between providers and consumers. The CRT
also has the authority to review the efficiency of service providers and order
the liquidation of monopolistic service providers which are found to be
inefficient. Where competition is lacking, the CRT may also set fixed fees for
services.
 
  The CRT restricts the activities of telephone service providers in order to
ensure free competition in the marketplace. For example, users may not be
required to purchase other services together with telephone service or be
required to purchase telephone equipment. Service providers are obligated to
permit other licensed service providers access to their telephone networks on
the basis of "equal access--equal fees."
 
  Local telephone service providers are free to set their own fees within
maximum and minimum limits set by the CRT. The minimum is the cost of
providing the service and the maximum is set for each service provider based
on its expenses and infrastructure investment. The maximum and minimum limits
are set for five-year periods and adjusted annually for inflation. The limits
can be modified within the five-year period if there is a prior agreement
between the CRT and the service provider to do so or in extraordinary
circumstances.
 
  Domestic and international long distance service has been provided
exclusively by TELECOM, which has had a monopoly on international and long
distance calls. However, in 1995, the Colombian government announced its
intention to open the long distance market to competition. The CRT has
established a process under which the opening of the long distance market to
competition is to be reviewed. The conditions for a new entrant include: (i)
an initial payment of $150 million for a ten-year license, which is
automatically renewed at no cost for an additional ten-year period and a
monthly payment of 5% of the gross revenues to the Ministry of Communications
payable over the duration of the license; (ii) the members of the consortium
must have at least 400 million minutes of international long distance traffic;
(iii) the operation of a minimum of 150,000 local telephone lines in Colombia
but in no case serving over 35% of the Colombian telephone market; and (iv)
the provision of universal service to a wide range of municipalities
throughout Colombia. It is expected that tariffs will be under a regulated
competitive system until 1999. The Company believes that the deregulation of
the long distance market will, as it has in other countries, serve to
stimulate phone usage, due to the fact that price competition is likely to
lower tariffs to the consumer. The Company does not currently expect that it
would qualify to be a new entrant into the long distance market in the near
future.

                      CERTAIN RELATED PARTY TRANSACTIONS
 
INGENIO RIOPAILA, S.A. AND INGENIO CENTRAL CASTILLA, S.A. SHARES
 
  Transtel and Gonzalo Caicedo Toro have entered into several transactions. In
the first of these transactions, during 1996, Mr. Caicedo pledged to certain
banks part of his shares in two Colombian companies, Ingenio Riopaila, S.A.
and Ingenio Central Castilla, S.A. (the "Caicedo Shares") as collateral for
loans that such banks made to Transtel in the principal amount of Ps14.6
billion ($11.7 million) (the "Secured Loans"). In the second transaction,
during the first quarter of 1997, Transtel borrowed Ps6.9 billion ($5.5
million) (the "Other Loans") and loaned the proceeds to Mr. Caicedo (the
"Caicedo Loan"). Mr. Caicedo used the proceeds from the Caicedo Loan to remove
certain liens from certain other shares of Ingenio Riopaila, S.A. and Ingenio
Central Castilla, S.A. owned by him. Mr. Caicedo then created a trust (the
"Caicedo Trust") that borrowed from third parties Ps21.5 billion ($17.3
million) (the "Trust Loan"). In April through July 1997, Mr. Caicedo used
Ps6.9 billion ($5.5 million) of the proceeds of this loan to repay the Other
Loans on behalf of Transtel. The repayment of the Other Loans by Mr. Caicedo,
on behalf of Transtel, was credited by Transtel as a repayment by Mr. Caicedo
of the Caicedo Loan. Mr. Caicedo used the remaining proceeds of the Trust Loan
(Ps14.6 billion ($11.7 million)) to make a capital contribution, in July 1997,
to Transtel, in partial satisfaction of the Equity Contribution. Transtel used
this money for the repayment of the Secured Loan. In addition, in July 1997,
Mr. Caicedo made a partial equity contribution of Ps0.8 billion ($660,000).
 
CERTAIN OTHER TRANSACTIONS WITH GONZALO CAICEDO TORO
 
  In addition to the transactions outlined above, the Company has been
involved in a number of transactions with Mr. Caicedo. In 1995, the Company
loaned Mr. Caicedo a total of approximately Ps8.4 billion ($6.7 million) of
which Mr. Caicedo repaid approximately Ps6.6 billion ($5.4 million) of that
loan in the same year. In 1996, the Company lent Mr. Caicedo an additional
approximately Ps9.2 billion ($7.4 million). These loans were repaid
 
                                      82
<PAGE>
 
in full by Mr. Caicedo in 1996 with (i) approximately Ps6.5 billion ($5.2
million) in cash, (ii) the assignment of a 2,000 square meter building located
in the municipality of Cali that the Company valued at approximately
Ps1.7 billion ($1.4 million), and (iii) the transfer by Mr. Caicedo of the
capital stock of GCT & Cia., which owns 7.59% of Colombina, the largest candy
manufacturer in Colombia, that the Company valued at approximately Ps2.7
billion ($2.2 million). As of August 31, 1997, Mr. Caicedo had repaid the
balance of additional net loans made to him in 1997 of Ps1.4 billion ($1.1
million), including the Caicedo Loan discussed above. The loans to Mr. Caicedo
were non-interest bearing and had no maturity dates.
 
PURCHASE AGREEMENTS AND LEASE AGREEMENTS WITH GLOBAL
 
  As part of the Company's tax planning, Global Telecommunications Operations,
Inc. ("Global"), a British Virgin Island company owned by the same
shareholders who own Transtel, has entered into purchase agreements and
letters of intent with Siemens for the purchase of certain telecommunications
equipment to be leased by Global to the Operating Companies to develop their
respective networks according to the Expansion Plan. In connection with these
equipment purchases, Global and the Company have entered into or intend to
enter into long-term equipment financing arrangements with Siemens under which
Siemens will provide financing for up to 85% of the total cost of such
equipment, or approximately $93.4 million. See "Description of Existing
Indebtedness--Global-Siemens Arrangements" for the terms of the existing
financing arrangements, and see "Risk Factors--Contingency of Vendor
Financing." Global in turn has entered into or intends to enter into lease
agreements with the Operating Companies for the lease of such equipment. As
security for these arrangements, Global has assigned to Siemens the lease
payments under the Global leases in case an event of default occurs and is
continuing under the Purchase Agreements. See "Description of Existing
Indebtedness--Global-Siemens Arrangement."
 
UNDERTAKINGS BY GLOBAL REGARDING INDEBTEDNESS AND LINE OF BUSINESS
 
  As a condition precedent to the Offering, Global entered into a Letter of
Undertaking, among Global, Siemens, Transtel and the Indenture Trustee (the
"Global Undertaking Letter"), whereby Global agreed that it would incur
additional indebtedness only if Transtel and the Operating Companies are in
compliance with the covenant described under "Description of the Senior
Notes--Certain Covenants--Limitation on Indebtedness" after giving effect to
any lease or guaranty arrangements entered into by Transtel or any Operating
Company in connection with such indebtedness and such indebtedness is used for
the purchase of telecommunications equipment to be leased to an Operating
Company. Pursuant to the Global Undertaking Letter, Global has also agreed not
to engage, directly or indirectly, in any business other than in the business
of purchasing telecommunications equipment and the leasing of such equipment
to the Operating Companies. In addition, Global has agreed that to the extent
it sells or otherwise disposes of any equipment leased under the Global Leases
(collectively, the "Equipment"), it will apply all cash proceeds received by

Equipment to prepay on a pro rata basis the Senior Notes and any amounts owing
by Global to Siemens under the Global Purchase Agreements.

                        DESCRIPTION OF THE CERTIFICATES
 
  Pursuant to the terms of the Trust Agreement, the Pass Through Trustee will
issue the Exchange Certificates on behalf of the Trust and exchange the
Original Certificates for the Exchange Certificates. The Certificates will
represent undivided beneficial interests in the assets of the Trust. The terms
of the Exchange Certificates are substantially identical to the terms of the
Original Certificates, except that the Exchange Certificates will have been
registered under the Securities Act and will not contain terms restricting
transfer of such Exchange Certificates. This summary of certain provisions of
the Certificates and the Trust Agreement does not purport to be complete and
is subject to, and qualified in its entirety by reference to, all the
provisions of the Trust Agreement, including the definitions therein of
certain terms. Wherever particular defined terms of the Trust Agreement are
referred to herein, such defined terms are incorporated herein by reference. A
copy of the form of the Trust Agreement is available without charge upon
request from the Pass Through Trustee.
 
CERTIFICATES
 
 General
 
  Legal title to the Senior Notes will be held at all times by the Trust as a
separate legal entity, except where the laws of any jurisdiction where the
Senior Notes are located require title to be held by a trustee in which case
legal title will be held by the Pass Through Trustee in trust for the benefit
of the Certificateholders. Each Certificate will represent a pro rata share of
the principal amount of the Senior Notes held by the Trust as well as any
other property held by the Trust from time to time, including all payments of
principal, interest, redemption premium, if any, and Additional Amounts, if
any, paid by the Company in respect of the Senior Notes.
 
 Payments and Distributions
 
  All payments of principal, interest, redemption premium or other amounts in
respect of the Senior Notes received by, or on behalf of, the Trust will to
the extent reasonably practicable, be distributed to Certificateholders on the
date such payments are received. From and after October 28, 1997, the Senior
Notes will bear interest at a rate of 12 1/2% per annum payable semiannually
in cash on each May 1 and November 1 of each year, (each referred to herein as
an "Interest Payment Date") commencing May 1, 1998. Interest distributions
made on each May 1 and November 1 will be paid to the persons who are the
registered Certificateholders on the April 15 and October 15, as the case may
be, immediately preceding such Interest Payment Date. Each Certificateholder
will be entitled to receive a pro rata share of any payments received by, or
on behalf of, the Pass Through Trustee on behalf of the Trust in respect of
the Senior Notes.
 
 Voting Rights
 
  So long as the Senior Notes are held by the Trust or the Pass Through
Trustee, as the case may be, the Pass Through Trustee will not (i) direct the
time, method and place of conducting any proceeding for any remedy available
to the Indenture Trustee, or execute any trust or power conferred on the Pass
Through Trustee with respect to the Senior Notes, (ii) waive any past default
that is waivable under the Senior Notes, (iii) exercise any right to rescind
or annul a declaration that the Senior Notes are due and payable, (iv) consent
to any amendment, modification or termination of the Indenture or the Senior
Notes, where such consent is required, without, in each case, obtaining the
prior approval of a Majority In Interest of Certificateholders, except that if
such consent under the Indenture would require the consent of each holder of
Senior Notes affected thereby, no such consent will be given by the Pass
Through Trustee without the prior consent of each Certificateholder (see
"Description of the Senior Notes--Modification and Waiver"), or (v) take any
other action, except as described below. If the Indenture Trustee requests the
Pass Through Trustee to take any action with respect to the Senior Notes,
including, but not limited to, a request for its consent to any amendment,
modification, waiver or supplement under the Indenture, the Pass Through
Trustee will immediately mail a notice to each Certificateholder registered as
of the date of such notice of the proposed action, and will take such action
with respect to the Senior Notes as it is instructed by the
Certificateholders; provided, however, that the Pass Through Trustee will not
be required to take any action with respect to the Senior Notes, the
Indenture, or the Certificates if it has not been assured of being indemnified
therefor.
 
                                      84
<PAGE>
 
  Any required approval of the Certificateholders may be given at a meeting of
Certificateholders convened for such purpose or pursuant to their written
consent. The Pass Through Trustee will cause a notice of any meeting at which
Certificateholders are entitled to vote, or of any matter upon which action by
written consent of such Certificateholders is to be taken, to be given to each
Certificateholder in the manner set forth the Trust Agreement.
 
 Amendment of Trust Agreement
 
  The Trust Agreement may be amended from time to time by the Pass Through
Trustee and the Company, without the consent of the Certificateholders, to
cure any ambiguity, to correct or supplement any provision in the Trust
Agreement which may be defective or inconsistent with any other provision, or
to make any other provisions with respect to matters or questions arising
under the Trust Agreement, provided that such amendment shall not adversely
affect the interests of the Certificateholders.
 
  The Trust Agreement may be modified or amended by the Pass Through Trustee
and the Company with the consent of a Majority In Interest of the
Certificateholders; provided, however, that no such modification or amendment
may, without the consent of each Certificateholder affected thereby, (i)
reduce the amount or delay the timing of any distribution on the Certificates,
(ii) have the effect of any of the events described in "Description of the
Senior Notes--Modification and Waiver," or (iii) otherwise adversely affect
such Certificateholder.
 
  Prior to the execution of any amendment, the Pass Through Trustee will be
entitled to receive an opinion of counsel that the amendment conforms to the
requirements of the Trust Agreement.
 
 Termination of the Pass Through Trust
 
  Pursuant to the Trust Agreement, the Trust shall terminate upon the
distribution to all Certificateholders of all amounts required to be
distributed to them pursuant to the Trust Agreement and the disposition of all
funds or property held by the trust.
 
 Events of Default and Certain Rights Upon an Event of Default
 
  An event of default under the Trust Agreement (a "Certificate Event of
Default") is defined as the occurrence and continuance of an Event of Default
under the Indenture (an "Indenture Default"). For a description of the
Indenture Defaults, see "Description of the Senior Notes--Events of Default."
 
  The Trust Agreement provides that as long as an Indenture Default has
occurred and is continuing with respect to the Senior Notes, the Pass Through
Trustee will exercise such rights and take such actions with respect to the
Certificates and the Senior Notes as it is instructed to take pursuant to the
written directions of Certificateholders representing the required percentage
set forth in the Trust Agreement.
 
  The Indenture provides that if an Indenture Default has occurred and is
continuing with respect to the Senior Notes, the Indenture Trustee may declare
the unpaid principal amount of the Senior Notes immediately due and payable,
together with any interest accrued thereon. Under certain circumstances the
Senior Notes and any accrued and unpaid interest thereon automatically will
become due and payable without action by the Indenture Trustee. See
"Description of the Senior Notes--Events of Default."
 
  Any amount paid to the Pass Through Trustee, on behalf of the Trust as
holder of the Senior Notes, by the Indenture Trustee under the Indenture
following an Indenture Default will be applied first, to cover all fees,
indemnity costs, expenses and compensation of the Pass Through Trustee; and
second, will thereafter be applied as a distribution to the Certificateholders
in accordance with the Trust Agreement.

                         DESCRIPTION OF THE GUARANTEES
 
GUARANTEE
 
 General
 
  On October 28, 1997 the Company executed the Original Certificate Guarantee,
for the benefit of the Original Certificateholders, whereby the Company fully,
irrevocably and unconditionally guaranteed all of the Trust's obligations under
the Original Certificates. Concurrently with the issuance of the Exchange
Certificates by the Trust, the Company will execute a like guarantee (the
"Exchange Certificate Guarantee"), for the benefit of the Exchange
Certificateholders, whereby the Company will fully, irrevocably and
unconditionally guarantee all of the Trust's obligations under the Exchange
Certificates. The Certificate Guarantee and the Exchange Certificate Guarantee
(together the "Certificate Guarantees") will have substantially identical
terms. Marine Midland Bank will act as guarantee trustee (together with any
successor guarantee trustee, the "Guarantee Trustee") under the Certificate
Guarantees.
 
  The Certificate Guarantees are guarantees by the Company of (i) the punctual
payment of the full amount, when due, of the principal of and interest on, and
fees and expenses due pursuant thereto, and (ii) the full and timely payment as
if payment had been made on a full and timely basis on the Senior Notes. The
Company's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Company to the Certificateholders.
 
  The Certificate Guarantees are irrevocable guarantees on a senior basis of
the Trust's obligations under the Certificates, and are not guarantees of
collection (i.e., the guaranteed party may institute a legal proceeding
directly against the Company (a "Direct Action") to enforce its rights under
the Certificate Guarantees without first instituting a legal proceeding against
any other person or entity). The Certificate Guarantees are held by the
Guarantee Trustee for the benefit of the Certificateholders. The Certificate
Guarantees will not be discharged except by payment of the Guarantee Payments
in full to the extent not paid by the Trust. The Trust Agreement provides that
each Certificateholder by acceptance thereof agrees to the provisions of the
Certificate Guarantees and the Indenture.
 
 Amendments and Assignment
 
  The Certificate Guarantees may not be amended without the prior approval of
Certificateholders of not less than a majority in aggregate principal amount of
the Certificates outstanding.
 
 Event of Default
 
  An event of default under the Certificate Guarantees will occur upon the
failure of the Company to perform any of its payment obligations thereunder.
The Certificateholders of not less than a majority in aggregate principal
amount of the Certificates outstanding have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee in respect of the Certificate Guarantees or to direct the
exercise of any trust or power conferred upon the Guarantee Trustee under the
Certificate Guarantees.
 
  Any registered Certificateholder may institute a legal proceeding directly
against the Company to enforce its rights under the Certificate Guarantees
without first instituting a legal proceeding against the Trust, the Guarantee
Trustee or any other person or entity.
 
 Information Concerning the Guarantee Trustee
 
  The duties of the Guarantee Trustee are subject to limitations and
qualifications substantially similar to those described with respect to the
Pass Through Trustee under "--Information Concerning the Pass Through Trustee."
 
                                       86
<PAGE>
 
 Governing Law
 
  The Certificate Guarantees will be governed by and construed in accordance
with the laws of the State of New York.
 
 Enforcement of Civil Liabilities
 
  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 out of the
Certificate Guarantees. See "Enforcement of Civil Liabilities" and
"Enforcement of Foreign Judgments in Colombia."
 
REPORTS AND NOTICES
 
  Upon receipt of any annual and quarterly financial statements from the
Company under the Indenture, the Trust will forward a copy of such financial
statements to the Pass Through Trustee and the Registrar. See "Description of
the Senior Notes--Certain Covenants--Reports." Notices in respect of the
Certificates will be given by mail, first-class postage prepaid, to each
registered Certificateholder at the address of such Certificateholder set
forth in the securities register maintained by the Certificate Registrar with
respect to the Certificates. So long as the Certificates are represented by a
Global Certificate or Global Exchange Certificate, notices to the
Certificateholders may be given by delivery of the relevant notice to DTC,
Euroclear and Cedel for communication by them to the relevant account holders.
 
  If, by reason of the suspension of the mails or for any other reason, it is
impracticable to give notice to the Certificateholders in the manner described
above, then such notification in lieu thereof as may be made by, or on behalf
of, the Pass Through Trustee will constitute sufficient provision of such
notice, if such notification, so far as may be practicable, approximates the
terms and conditions of the notice in lieu of which it is given. Neither the
failure to give notice nor any defect in any notice given to any particular
Certificateholder will affect the sufficiency of any notice with respect to
other Certificates. Such notices will be deemed to have been given on the date
of mailing.
 
ADDITIONAL AMOUNTS
 
  All payments made by the Trust under or in respect of the Certificates will
be made free and clear of and without withholding or deduction for or on
account of any present or future tax, duty, fee, levy, impost, assessment or
other governmental charge (including penalties, interest, additions to tax and
any other liabilities related thereto) (collectively referred to as "Taxes")
imposed or levied by or on behalf of Colombia, the United States, or any other
jurisdiction in which the Trust, the Company or any of the Company's
Restricted Subsidiaries is organized or engaged in business for tax purposes
(each, a "Taxing Authority"). If the Trust is required to withhold or deduct
or if the Trust is otherwise required to pay any amount for or on account of
Taxes imposed by a Taxing Authority, from or in respect of any payment made
under or with respect to the Certificates, the Trust will pay such additional
amounts ("Additional Amounts") as may be necessary so that the net amount
received by each Certificateholder (including Additional Amounts) after such
withholding or deduction or other payment of Taxes will not be less than the
amount the Certificateholder would have received if such Taxes had not been
withheld or deducted or paid; provided that no Additional Amounts will be
payable with respect to a payment made to a Certificateholder (A) with respect
to any Tax which would not have been imposed, payable or due: (i) but for the
existence of any present or former connection between such Certificateholder
(or the beneficial owner of, or other person having a right to acquire an
interest in, such Certificate) and the relevant Taxing Authority, other than
the mere holding of a Certificate; (ii) if the Certificates are held in
definitive registered form and the presentation of the definitive Certificate
for payment had occurred within 30 days after the date such payment was due
and payable or was provided for, whichever is later; or (iii) but for the
failure of a Certificateholder that is not a "United States Person" as defined
in Section 7701(a)(30) of the United States Internal Revenue Code of 1986, as
amended, to comply with certification, information or other reporting
requirements concerning the nationality, residence, identity or business
activity within the United States of such
 
                                      87
<PAGE>
 
Certificateholder (or, if applicable, the beneficial owner of, or other person
having a right to acquire an interest in, the Certificate) if such compliance
is a condition to such Taxes not having been imposed, payable or due with
respect to the payment or (B) if the beneficial owner of, or other person
having a right to acquire an interest in, such Certificate had been the
Certificateholder and would not be entitled to the payment of Additional
Amounts under (A). Except as provided in the second succeeding paragraph
below, in no event will Additional Amounts be payable with respect to any tax
that is payable otherwise than by withholding from payment of or with respect
to principal of, or interest on, the Certificates.
 
  The Trust will also (i) make such withholding or deduction and (ii) remit
the full amount deducted or withheld to the relevant Taxing Authority in
accordance with applicable law. The Trust will make reasonable efforts to
obtain certified copies of tax receipts evidencing the payment of any Taxes so
deducted or withheld from each Taxing Authority imposing such Taxes. The Trust
will furnish to the Certificateholders, within 60 days after the date that the
payment of any Taxes so deducted or withheld is due pursuant to applicable
law, either certified copies of tax receipts evidencing such payment by the
Trust or, if such receipts are not obtainable, other evidence of such payments
by the Trust.
 
  In addition, the Trust will, upon written request of a Certificateholder
(subject to the exclusions set forth in (A) and (B) of the first paragraph
above), and provided that reasonable supporting documentation is provided,
reimburse each such Certificateholder for the amount of any Taxes levied or
imposed by any Taxing Authority and paid by such Certificateholder as a result
of payments made by the Trust to such Certificateholder with respect to the
Certificates. Any payment pursuant to this paragraph shall be an Additional
Amount.
 
  Whenever in the Trust Agreement, Indenture or in this Prospectus there is
mentioned in the context of the payment of amounts based upon the principal
of, premium, if any, interest or of any other amount payable under or with
respect to any Certificate, 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.
 
  In addition, the Trust will pay any stamp, issue, transfer, sales, use,
value-added, property, registration, documentary, enforcement or other similar
taxes and other duties (including interest and penalties) payable to any
Taxing Authority in respect of the creation, issue or offering of the
Certificates or any other documents directly related to such creation, issue
or offering.
 
REMOVAL AND RESIGNATION OF THE PASS THROUGH TRUSTEE; APPOINTMENT OF SUCCESSORS
 
  A Majority In Interest of the Certificateholders may remove the Pass Through
Trustee for cause or, if a Certificate Event of Default has occurred and is
continuing, with or without cause. If the Pass Through Trustee is removed by
the Certificateholders, a successor shall be appointed by the
Certificateholders holding at least 25% in principal amount of Certificates.
If the Pass Through Trustee resigns, the Company shall immediately appoint its
successor. If the Company fails to appoint a successor, the Certificateholders
holding at least 25% in principal amount of the outstanding Certificates may
appoint a successor. If a successor shall not have been appointed by the
Company or by the Certificateholder holding at least 25% in aggregate amount
of Certificates, within 30 days of notice of such resignation or removal, the
Pass Through Trustee or any Certificateholder may petition a court in the
State of Delaware to appoint a successor. Any Pass Through Trustee must meet
the applicable requirements of Section 3807 of the Delaware Business Trust
Act, 12 Del. c. (S)3801 et seq. Any Pass Through Trustee must at the time of
appointment have capital and surplus of at least $50,000,000. No resignation
or removal of the Pass Through Trustee and no appointment of a successor
trustee shall be effective until the acceptance of appointment by the
successor trustee in accordance with the provisions of the Trust Agreement.
 
PAYMENT AND PAYING AGENCY
 
  Payments in respect of the Certificates will be made to DTC, which payments
will be credited to the relevant accounts at DTC on the applicable payment
dates or, if the Certificates are not held by DTC, such payments will
 
                                      88
<PAGE>
 
be made by check mailed to the address of the Certificateholder entitled
thereto as such address appears on the securities register for the
Certificates. Marine Midland Bank (Marine Midland Bank and any co-paying agent
chosen by the Pass Through Trustee and acceptable to the Company, the "Paying
Agent") will initially be the paying agent. The Paying Agent will be permitted
to resign as Paying Agent upon 30 days' written notice to the Pass Through
Trustee and the Company, in which event the Company will appoint a successor
to act as Paying Agent.
 
  If any day for payment and other amounts payable in respect of the
Certificates is not a Business Day (as defined herein) in the applicable place
of payment, the Certificateholders will not be entitled to payment until the
next Business Day following such day in the place of payment or to any
interest or other sums in respect of such postponed payment. For purposes of
the Trust Agreement, "Business Day" means a day (other than Saturday and
Sunday) on which DTC, Euroclear and banks in New York, Delaware and Colombia
are open for business.
 
CERTIFICATE REGISTRAR AND TRANSFER AGENT
 
  Marine Midland Bank will act as registrar and transfer agent for the
Certificates (the "Certificate Registrar").
 
  Registration of transfers of Certificates will be effected without charge by
or on behalf of the Trust, other than amounts with respect to any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The Certificate Registrar will not be required to register or cause
to be registered the transfer of the Certificates after the Exchange
Certificates have been called for redemption.
 
GOVERNING LAW
 
  The Trust Agreement and the Certificates will be governed by and construed
in accordance with the laws of the State of Delaware.
 
INFORMATION CONCERNING THE PASS THROUGH TRUSTEE
 
  The Pass Through Trustee, other than during the occurrence and continuance
of a Certificate Event of Default, will perform only such duties as are
specifically set forth in the Trust Agreement. The Pass Through Trustee is
under no obligation to exercise any of the powers vested in it by the Trust
Agreement at the request of any Certificateholder unless it is offered
reasonable indemnity against the costs, expenses and liabilities that might be
incurred thereby. The Pass Through Trustee is not required to expend or risk
its own funds or otherwise incur personal financial liability in the
performance of its duties if the Pass Through Trustee reasonably believes that
repayment or adequate indemnity is not reasonably assured to it.

<PAGE>
 
                        DESCRIPTION OF THE SENIOR NOTES
 
GENERAL
 
  The Senior Notes were issued under an Indenture (the "Indenture"), dated as
of October 28, 1997, between the Company and Marine Midland Bank, as indenture
trustee (in such capacity, the "Indenture Trustee"). The Indenture permits the
issuance of up to $180.0 million of Senior Notes thereunder, $150.0 million of
which were offered pursuant to the Offering consummated on October 28, 1997
(the "Initial Senior Notes") and $30.0 million of which may be offered in the
future (the "Additional Senior Notes") subject to compliance with the first
paragraph of clause (a) of the "--Limitation on Indebtedness" covenant below.
For purposes of this section of the Prospectus, the term Senior Notes shall
mean the Initial Senior Notes and the Additional Senior Notes. In the event of
such a future offering, the Additional Senior Notes would have the same terms
as the Initial Senior Notes (including payment dates and maturity) and rank
pari passu with the Initial Senior Notes in all respects. The following
summary of certain provisions of the Indenture does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all the
provisions of the Indenture, including the definitions of certain terms
therein and those terms made a part thereof by the Trust Indenture Act.
Certain capitalized terms used in this section of the Prospectus are defined
below. Whenever particular Sections or defined terms of the Indenture not
otherwise defined herein are referred to, such Sections or defined terms are
incorporated herein by reference. A copy of the Indenture is available upon
request from the Company or the Indenture Trustee. Concurrently with the
issuance of the Original Certificates, the Trust invested the proceeds
therefrom in the Senior Notes issued by the Company. For purposes of this
section of the Prospectus, "Holders" shall mean the holders of the Senior
Notes. The Trust is the sole Holder of the Senior Notes.
 
  The Senior Notes were issued in fully registered form only, without coupons,
in denominations of $1,000 and integral multiples thereof. Initially, Marine
Midland Bank will act as Paying Agent and Registrar for the Senior Notes. The
Senior Notes may be presented for registration or transfer and exchange at the
offices of the Registrar, which will be the Registrar's corporate trust office
at 140 Broadway, 12th Floor, New York, New York 10005. The Company may change
any Paying Agent and Registrar without notice to the Holders. The Company will
pay principal (and premium, if any) on the Senior Notes at the Paying Agent's
corporate trust office in New York, New York. At the Company's option,
interest may be paid by check mailed to the registered address of the Holders.
 
PRINCIPAL, MATURITY AND INTEREST
 
  The Senior Notes are limited in aggregate principal amount to $180 million.
The Senior Notes will mature on November 1, 2007, and bear interest from
October 28, 1997 at a rate of 12 1/2% per annum payable semiannually in cash
on each May 1 and November 1 (each an "Interest Payment Date"), commencing May
1, 1998. Interest on the Senior Notes will be computed on the basis of a 360-
day year of twelve 30-day months.
 
REDEMPTION
 
 Optional Redemption
 
  The Senior Notes are not redeemable at the Company's option prior to
November 1, 2002. Thereafter, the Senior Notes will be subject to redemption
at the option of the Company, in whole or in part, upon not less than 30 nor
more than 60 days' prior notice, at the following redemption prices (expressed
in percentages of the principal amount), plus accrued and unpaid interest, if
any, to the redemption date (subject to the right of the Holders to receive
interest due on an Interest Payment Date), if redeemed during the 12-month
period commencing November 1 of the years set forth below:

<PAGE>
 
  Notwithstanding the foregoing, in the event of the sale by the Company prior
to November 1, 2000 of at least $25 million of its Capital Stock (other than
Disqualified Stock) in one or more Public Equity Offerings, or to one or more
Strategic Equity Investors, the Company may, at its option, use the Net Cash
Proceeds of such sale or sales of Capital Stock to redeem up to 35% of the
Senior Notes at a redemption price equal to 112.50% of the principal amount
thereof plus accrued and unpaid interest thereon, if any, to the date of
redemption; provided that at least 65% of the initial principal amount of the
Senior Notes (including in such initial principal amount, the initial
principal amount of any Additional Senior Notes issued as contemplated by the
first paragraph under the heading "--General" above, if issued prior to the
date of the redemption pursuant to this paragraph) remains outstanding
immediately after such redemption. In order to effect the foregoing redemption
with the proceeds of any such sale of Capital Stock, the Company shall make
such redemption not more than 120 days after the consummation of any such sale
or sales of Capital Stock.
 
 Mandatory Redemption; Change of Control; Certain Asset Sales
 
  The Company is not required to make any mandatory redemption or sinking fund
payments in respect of the Senior Notes. However, (i) upon the occurrence of a
Change of Control, the Company is obligated to make an Offer to Purchase (as
defined in "--Offer to Purchase Upon Change of Control") all outstanding
Senior Notes at a price of 101% of the principal amount thereof plus accrued
and unpaid interest, if any, to the date of purchase and (ii) upon the
occurrence of an Asset Sale, the Company may be obligated to make a Net
Proceeds Offer (as defined in "--Certain Covenants--Limitation on Asset
Sales") for all or a portion of the outstanding Senior Notes at a price of
100% of the principal amount thereof plus accrued and unpaid interest, if any,
to the date of repurchase. See "--Offer to Purchase Upon Change of Control"
and "--Certain Covenants--Limitation on Asset Sales," respectively.
 
 Selection; Effect of Redemption Notice
 
  In the case of any partial redemption, selection of the Senior Notes for
redemption will be made by the Indenture Trustee or Registrar on a pro rata
basis by lot or in accordance with any other method the Indenture Trustee
considers fair and appropriate. The notice of redemption relating to such
Senior Note shall state the portion of the principal amount thereof to be
redeemed. A new Senior Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder upon cancellation of
the original Senior Note. Upon redemption, unless the Company defaults in
providing the funds for such redemption, interest on Senior Notes called for
redemption will cease to accrue from and after the date fixed for redemption
and, upon redemption, such Senior Notes will then cease to be outstanding.
 
OFFER TO PURCHASE UPON CHANGE OF CONTROL
 
  The Indenture provides that upon the occurrence of a Change of Control, each
Holder will have the right to require that the Company purchase all or a
portion of such Holder's Senior Notes pursuant to the offer described below
(the "Offer to Purchase"), at a purchase price equal to 101% of the principal
amount thereof plus accrued and unpaid interest thereon, if any, to the date
of purchase.
 
  Within 30 days following the date upon which a Change of Control occurs, the
Company must send, by first class mail, a notice to each Holder, with a copy
to the Indenture Trustee and Paying Agent, which notice shall govern the terms
of the Offer to Purchase. Such notice shall state, among other things, the
purchase date, which must be no earlier than 30 days nor later than 45 days
from the date such notice is mailed, other than as may be required by law (the
"Change of Control Payment Date"). Holders will be required to surrender the
Senior Notes it wishes to have redeemed, with the form entitled "Option of
Holder to Elect Purchase" on the reverse of the Senior Note or Notes
completed, to the Paying Agent at the address specified in the Senior Notes
prior to the close of business on the third Business Day prior to the Change
of Control Payment Date.
 
  If an Offer to Purchase 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 the Senior Notes that might be delivered by the Holders seeking
to accept the Offer to Purchase. In the event the Company is required to
purchase outstanding

<PAGE>
 
Senior Notes pursuant to an Offer to Purchase, the Company expects that it
would seek third-party financing to the extent it does not have available
funds to meet its purchase obligations. However, the Indenture limits the
Company's ability to incur Indebtedness (see "--Certain Covenants--Limitation
on Indebtedness") and there can be no assurance that the Company would be able
to obtain such financing.
 
DISBURSEMENT OF FUNDS--ESCROW ACCOUNT
 
  As provided in the Indenture, the Company has placed approximately $35.0
million of the net proceeds realized from the sale of the Senior Notes,
representing funds sufficient to pay the first four interest payments on the
Initial Senior Notes, in an escrow account (the "Escrow Account") held by the
Escrow Agent for the benefit of Holders of the Senior Notes and the Indenture
Trustee in accordance with the Escrow and Disbursement Agreement. The Company
entered into the Escrow and Disbursement Agreement, which provides, among
other things, that funds may be disbursed from the Escrow Account only to pay
interest on the Senior Notes (or, if any Senior Notes have been retired by the
Company, funds representing the interest payment on the retired Senior Notes
may be paid to the Company on the date of retirement) and, upon certain
repurchases or redemptions of Senior Notes, to pay principal of and premium,
if any, on the Senior Notes being repurchased or redeemed. Pending such
disbursement, the Company will cause such funds contained in the Escrow
Account to be invested in Marketable Securities. Interest earned on these
Marketable Securities will be added to the Escrow Account. The Escrow Account
will be held in the corporate trust office of the Escrow Agent in New York.
 
  The Company granted to the Indenture Trustee for the benefit of the Holders
a security interest in the Escrow Account under the Escrow and Disbursement
Agreement. Such security interest secures the payment and performance when due
of all of the Obligations of the Company under the Indenture with respect to
the Senior Notes, as provided in the Escrow and Disbursement Agreement. The
ability of the Holders to realize upon any such funds or securities may be
subject to certain bankruptcy law limitations in the event of the bankruptcy
of the Company.
 
  Upon the acceleration of the maturity of the Senior Notes or upon certain
redemptions and repurchases of the Senior Notes, the Escrow and Disbursement
Agreement provides for the foreclosure by the Indenture Trustee upon the net
proceeds of the Escrow Account. Under the terms of the Indenture, the proceeds
of the Escrow Account shall be applied to the Obligations under the Senior
Notes.
 
RANKING
 
  The Senior Notes are senior obligations of the Company ranking pari passu in
right of payment with all existing and future senior Indebtedness of the
Company and rank senior in right of payment to all existing and future
subordinated Indebtedness of the Company, if any. The Company is a holding
company that conducts substantially all of its operations through its
subsidiaries. Other than claims under the Intercompany Notes, the Senior Notes
are effectively subordinated to all existing and future liabilities and
Indebtedness of the Company's subsidiaries. Subject to certain limitations set
forth in the Indenture and as described under "--Limitations on Liens" below,
the Company and its Restricted Subsidiaries may incur Indebtedness which is
secured by assets of the Company and its Restricted Subsidiaries. Any right of
the Company to receive assets of the Company's Restricted Subsidiaries or any
future Restricted Subsidiaries of the Company, upon a Restricted Subsidiary's
liquidation or reorganization (and the consequent right of the Holders to
participate in those assets), are effectively subordinated to the claims of
that Restricted Subsidiary's creditors, except to the extent that the Company
is itself recognized as a creditor of such Restricted Subsidiary as in the
case of Indebtedness evidenced by Intercompany Notes, although other creditors
of such Restricted Subsidiary may be secured by certain assets of such
Restricted Subsidiary.
 
SECURITY
 
  The Senior Notes are secured by a first priority security interest in: (i)
the Intercompany Notes, which Intercompany Notes represent senior unsecured
obligations of each Restricted Subsidiary and rank senior in right of payment
to all existing and future subordinated Indebtedness of the respective
Restricted Subsidiary and pari
 
                                      92
<PAGE>
 
passu with all existing and future Senior Indebtedness of such Restricted
Subsidiary; and (ii) pending disbursement pursuant to the Escrow and
Disbursement Agreement, the Escrow Account and the Refinancing Account.

such Indebtedness to a Person not a Restricted Subsidiary shall be deemed, in
each case, to constitute an incurrence of such Indebtedness not permitted by
this clause (vi); (vii) Indebtedness of a Restricted Subsidiary issued to and
held by the Company; provided that (a) any subsequent issuance or transfer of
any Capital Stock which results in any such Restricted Subsidiary ceasing to be
a Restricted Subsidiary or any subsequent transfer of such Indebtedness to a
Person not a Restricted Subsidiary shall be deemed, in each case, to constitute
an incurrence of such Indebtedness not permitted by this clause (vii) and (b) if
such Indebtedness arises from loans or advances made to a Restricted Subsidiary
by the Company with the proceeds of the Senior Notes, such Indebtedness shall be
evidenced by an Intercompany Note; (viii) the incurrence by the Company or its
Restricted Subsidiaries of additional Indebtedness in an aggregate principal
amount not to exceed $10.0 million at any one time outstanding; (ix) the

(but, only as to clause (i), only to the extent the proceeds thereof are used to
purchase Senior Notes tendered in an Offer to Purchase made as a result of a
Change of Control), (ii), (iv), (v), (vii) and (viii) above or theretofore
incurred pursuant to this clause (ix) ("Refinancing Indebtedness"); provided
that: (a) the net proceeds of such Refinancing Indebtedness shall not exceed the

Indebtedness so extended, refinanced, renewed, replaced, substituted or refunded
(or if such Indebtedness was issued at an original issue

<PAGE>
 
discount, the face amount of such Indebtedness less the remaining unamortized
portion of the original issue discount of such Indebtedness at the time of the
repayment of such Indebtedness) and reasonable expenses incurred in connection
therewith; (b) the Refinancing Indebtedness shall have a final maturity not
sooner than, and an Average Life equal to or greater than, the final maturity
and remaining Average Life of the Indebtedness being extended, refinanced,
renewed, replaced or refunded; (c) if the Indebtedness being extended,
refinanced, renewed, replaced or refunded is subordinated in right of payment
to the Senior Notes, the Refinancing Indebtedness shall be subordinated in
right of payment to the Senior Notes pursuant to a Subordination Agreement;

(direct or indirect) with respect to any such Refinancing Indebtedness; and
(e) the Refinancing Indebtedness shall be unsecured, secured in compliance
with the "--Limitation on Liens" covenant, or, if the Indebtedness being
extended, refinanced, renewed, replaced or refunded is secured, the respective
Refinancing Indebtedness may be secured, but only to the same extent as the
Indebtedness being refinanced, renewed, replaced or refunded; (x) Indebtedness
of the Company or any Restricted Subsidiary (A) in respect of performance,
surety or appeal bonds provided in the ordinary course of business, (B) in
respect of Currency Agreements or Interest Rate Agreements incurred for the
purpose of hedging against currency or interest rate risks with respect to
Indebtedness incurred in accordance with the first paragraph of clause (a) of
"--Limitation on Indebtedness" and which the Company in good faith determines
is non-speculative in nature and is a bona fide hedge against fluctuations in
currency values or interest rates, respectively; provided, that in the case of
Currency Agreements that relate to other Indebtedness, such Currency Agreement
does not increase the Indebtedness of the obligor outstanding at any time
other than as a result of fluctuations in foreign currency exchange rates or
by reasons of fees, indemnities and compensation payable thereunder and in the
case of Interest Rate Agreements, the notional amount of such Interest Rate
Agreement does not exceed the underlying obligation or amount to which such
Interest Rate Agreement relates; and (C) arising from agreements providing for
indemnification, adjustment of purchase price or similar obligations, or from
Guarantees or letters of credit, surety bonds or performance bonds securing
any obligations of the Company or any of its Restricted Subsidiaries pursuant

the gross proceeds actually received by the Company or any Restricted
Subsidiary in connection with such disposition; and (xi) Guarantees by the
Company of operating leases expensed under GAAP of its Restricted
Subsidiaries; provided that the Company's Obligations under such Guarantees

this "--Limitation on Indebtedness" covenant, Liens on such Persons' assets or
obligations of such Persons with respect to letters of credit supporting
Indebtedness otherwise included in the determination of such particular amount
shall not be included. For purposes of determining compliance with this "--
Limitation on Indebtedness" covenant, (A) in the event that an item of
Indebtedness meets the criteria of more than one of the types of Indebtedness
described in the above paragraph, the Company shall classify such item of
Indebtedness and only be required to include the amount of such Indebtedness
in one of such types of Indebtedness and (B) the amount of Indebtedness issued
at a price that is less than the principal amount thereof shall be equal to
the amount of the liability in respect thereof determined in conformity with
GAAP. The Indenture further provides that, notwithstanding any other provision
of the "--Limitation on Indebtedness" covenant, the maximum amount of
Indebtedness that the Company or a Restricted Subsidiary may incur pursuant to
this "--Limitation on Indebtedness" covenant shall not be deemed to be
exceeded due solely to the result of fluctuations in the exchange rates of
currencies after the date of the respective incurrence of Indebtedness
otherwise in conformity with the provisions of this "--Limitation on
Indebtedness" covenant.

solely in shares of such Capital Stock held by holders of such Capital Stock
or in options, warrants, or other rights to acquire such shares of Capital
Stock), (ii) repurchase, redeem, retire or otherwise acquire for value any

Company could not incur at least $1.00 of Indebtedness under the first
paragraph of the "--Limitation on Indebtedness" covenant (without reliance
upon any of the exceptions in clauses (a)(i) through (xi) under "--Limitation
on Indebtedness") or (C) the aggregate amount expended for all Restricted
Payments (the amount so expended, if other than in cash, to be determined in
good faith by the Board of Directors, whose determination shall be conclusive
and evidenced by a Board Resolution) after the Issue Date shall exceed the sum
of (1) 50% of the aggregate amount of the Consolidated Net Income (or, if the
Consolidated Net Income is a loss, minus 100% of such loss) accrued on a

said date of declaration, such payment would comply with the foregoing
paragraph; (ii) the payment of dividends or distributions by a Restricted
Subsidiary on its Capital Stock to the Company or any other Restricted
Subsidiary that owns equity interests in the Restricted Subsidiary making the
respective payment; (iii) in connection with a payment of dividends or

right of payment to the Senior Notes, in exchange for, or out of the proceeds
of a substantially concurrent issuance of, shares of the Capital Stock of the
Company; (v) so long as no Default or Event of Default shall have occurred and
be continuing, a Permitted Refinancing; or (vi) Permitted Investments;

                                      95
<PAGE>
 
Subsidiaries and provided further that the aggregate investment in any
Restricted Subsidiary in the form of Intercompany Notes shall not exceed 20%
of the gross proceeds of the Notes. The amounts referred to in clauses (i),
(iii) and (iv) shall be included as Restricted Payments in any computation
made pursuant to the first paragraph above.
 
  Not later than the making of any Restricted Payment, the Company shall
deliver to the Indenture Trustee an Officers' Certificate (as defined in the
Indenture) stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant "--Limitation
on Restricted Payments" were computed.
 
 Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries
 
  So long as any of the Senior Notes are outstanding, the Company will not,
and will not permit any Restricted Subsidiary to, create or otherwise cause or
suffer to exist or become effective any consensual encumbrance or consensual
restriction of any kind on the ability of any Restricted Subsidiary to (i) pay

  The foregoing provisions shall not restrict any encumbrances or
restrictions: (i) existing on the Issue Date, including those in the Indenture
or in the Existing Indebtedness, and any Permitted Refinancings thereof;
provided that the encumbrances and restrictions in any such Permitted
Refinancings are in the aggregate not materially more restrictive than those
encumbrances or restrictions that are then in effect and that are being
extended, refinanced, renewed or replaced; (ii) existing under or by reason of
applicable law and not due to any contractual arrangement; (iii) in the case
of clause (iv) of the first paragraph of this covenant, (A) that restrict in a

asset, (B) existing by virtue of any transfer of, agreement to transfer,
option or right with respect to, or Lien on, any property or assets of the
Company or any Restricted Subsidiary not otherwise prohibited by the
Indenture, (C) arising or agreed to in the ordinary course of business, not
relating to any Indebtedness for borrowed money, and that do not, individually
or in the aggregate, detract from the value of property or assets of the
Company or any Restricted Subsidiary in any manner material to the Company or
any Restricted Subsidiary, (D) existing pursuant to any purchase money
obligations for property solely with respect to the property acquired or (E)
existing pursuant to any mortgage or construction financing that imposes
restrictions solely on the real property acquired or improved; (iv) with
respect to a Restricted Subsidiary and imposed pursuant to an agreement that
has been entered into for the sale or disposition of all or substantially all
of the Capital Stock of, or property or assets of, such Restricted Subsidiary;
or (v) included in Bank Indebtedness or Guarantees incurred pursuant to
clauses (iv) and (v) of the second paragraph of the "--Limitation on
Indebtedness" covenant, respectively, so long as, in the case of this clause
(v), the relevant restrictions in no event restrict payments to the Company to
be used by it to make payments of principal, interest or other amounts as
required pursuant to the terms of the Senior Notes or the Indenture other than
to require that no such payment be made if there is a default or event of
default with respect to the Bank Indebtedness or Guarantees. Nothing contained
in this "--Limitation on Dividend and Other Payment Restrictions Affecting
Restricted Subsidiaries" covenant shall prevent the Company or any Restricted
Subsidiary from (1) creating, incurring, assuming or suffering to exist any
Liens otherwise permitted in the "--Limitation on Liens" covenant or (2)
restricting the sale or other disposition of property or assets of the Company
or any of its Restricted Subsidiaries that secure Indebtedness of the Company
or any of its Restricted Subsidiaries.
 
 Limitation on the Issuance and Sale of Capital Stock of Restricted
Subsidiaries
 
  Under the terms of the Indenture, the Company will not sell, and will not
permit any Restricted Subsidiary, directly or indirectly, to issue or sell any
shares of Capital Stock of a Restricted Subsidiary (including options,
warrants or other rights to purchase shares of such Capital Stock) except (i)
to the Company, a Wholly-Owned Subsidiary or, in the case of Restricted
Subsidiaries, the Municipal Shareholders of such Restricted Subsidiary so long
as such Restricted Subsidiary remains a Subsidiary of the Company; (ii) if,
immediately after giving
 
                                      96
<PAGE>
 
effect to such issuance or sale, such Restricted Subsidiary would no longer
constitute a Restricted Subsidiary; (iii) issuances or sales to foreign
nationals of shares of Capital Stock of Restricted Subsidiaries, to the extent
required by applicable law; and (iv) issuances or sales of Capital Stock of
Restricted Subsidiaries to persons who after such issuance or sale will hold a
minority interest in such Restricted Subsidiary; provided that in the case of
clauses (ii) and (iv), the Company or such Restricted Subsidiary applies the
Net Cash Proceeds, if any, of any such sale in accordance with the "--
Limitation on Asset Sales" covenant described below.
 
 Limitation on Issuances of Guarantees by Restricted Subsidiaries
 
  The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company ("Guaranteed
Indebtedness"), unless (i) such Restricted Subsidiary simultaneously executes
and delivers a Subsidiary Guarantee and (ii) such Restricted Subsidiary waives
and will not in any manner whatsoever claim or take the benefit or advantage
of, any rights of reimbursement, indemnity or subrogation or any other rights
against the Company or any other Restricted Subsidiary as a result of any
payment by such Restricted Subsidiary under its Subsidiary Guarantee; provided
that this paragraph shall not be applicable to any Guarantee of any Restricted
Subsidiary that (A) (x) existed at the time such Person became a Restricted
Subsidiary and (y) was not incurred in connection with, or in contemplation
of, such Person becoming a Restricted Subsidiary or (B) Guarantees of Bank
Indebtedness incurred by the Company pursuant to clause (iv) of the second
paragraph of the "--Limitation on Indebtedness" covenant. If the Guaranteed
Indebtedness is (A) pari passu with the Senior Notes, then the Guarantee of
such Guaranteed Indebtedness shall be pari passu with, or subordinated to, the
Subsidiary Guarantee or (B) subordinated to the Senior Notes, then the
Guarantee of such Guaranteed Indebtedness shall be subordinated to the
Subsidiary Guarantee at least to the extent that the Guaranteed Indebtedness
is subordinated to the Senior Notes.
 
  Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary shall provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or
transfer, to any Person not an Affiliate of the Company, of all of the
Company's and each Wholly-Owned Subsidiary's Capital Stock in such Restricted
Subsidiary (which sale, exchange or transfer is not prohibited by the
Indenture) or (ii) the release or discharge of the Guarantee or other
Indebtedness which resulted in the creation of such Subsidiary Guarantee,
except a release or discharge by or as a result of payment under such
Guarantee.
 
  Under certain circumstances, the Company may cause the execution and
delivery of Subsidiary Guarantees. Each Subsidiary Guarantee delivered by a
Restricted Subsidiary is limited to such amount as will not, after giving
effect thereto, and to all other liabilities of such Restricted Subsidiary,
result in such amount constituting a fraudulent transfer or conveyance.
 
 Limitation on Transactions with Shareholders and Affiliates
 
  Under the terms of the Indenture, the Company will not, and will not permit
any Restricted Subsidiary to, directly or indirectly, enter into, renew or
extend any transaction (including, without limitation, the purchase, sale,
lease or exchange of property or assets, or the rendering of any service) with
any legal or beneficial owner (or any Affiliate of such holder) of 5% or more
of any class of Capital Stock of the Company or with any Affiliate of the
Company or any Restricted Subsidiary (each of the foregoing, an "Affiliate
Transaction"), unless: (i) such Affiliate Transaction is on terms that are no
less favorable to the Company or such Restricted Subsidiary than those that
would have been obtained at the time of such transaction or at the time of the
execution of the agreement providing therefor in a comparable arm's-length
transaction with a Person that is not such a Related Person and (ii) the
Company delivers to the Indenture Trustee: (x) with respect to any Affiliate
Transaction involving aggregate payments in excess of $250,000 but less than
$2.5 million, a resolution of the Board of Directors of the Company set forth
in an Officers' Certificate certifying that such Affiliate Transaction
complies with clause (i) above, (y) with respect to any Affiliate Transaction
involving aggregate payments equal to or greater than $2.5 million but less
than $15.0 million, a resolution of the Board of Directors of the Company set
forth in an Officers' Certificate certifying that such Affiliate Transaction
complies with clause (i) above and (A) that such Affiliate Transaction has
been approved by at least three disinterested directors of the Board of
 
                                      97
<PAGE>
 
Directors of the Company and, in any case, by a majority of the disinterested
directors of the Board of Directors of the Company or (B) a written opinion as
to the fairness to the Company or such Restricted Subsidiary from a financial
point of view issued by an independent internationally recognized investment
banking firm or independent Colombian investment banking firm with respect to
any such Affiliate Transaction, and (z) with respect to any Affiliate
Transaction involving aggregate payments equal to or greater than $15.0
million, a resolution of the Board of Directors of the Company set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (i) above and a written opinion as to the fairness to the Company or
such Restricted Subsidiary from a financial point of view issued by an
independent internationally recognized investment banking firm with respect to
any such Affiliate Transaction.
 
  Notwithstanding the foregoing, the following shall not be deemed Affiliate
Transactions: (i) any transaction between the Company and any of its
Restricted Subsidiaries or between Restricted Subsidiaries, provided such
transaction complies with clause (i) in the first paragraph above (other than
for amounts paid by a Restricted Subsidiary to the Company in respect of
corporate overhead); (ii) the payment of reasonable and customary regular fees
to directors of the Company who are not employees of the Company; (iii) any
payments or other transactions pursuant to any tax-sharing agreement between
the Company and any other Person with which the Company files a consolidated
tax return or with which the Company is part of a consolidated group for tax
purposes; (iv) Global I Leases, Global II Leases and Global III Leases, and
any extension, amendment, replacement or renewal thereof on substantially
similar terms; (v) any Restricted Payments not prohibited by the "--Limitation
on Restricted Payments" covenant; or (vi) equipment leases with Affiliates
entered into after the Issue Date; provided such leases comply with clause (i)
in the first paragraph above and the Company delivers to the Indenture Trustee
a resolution of the Board of Directors of the Company set forth in an
Officer's Certificate certifying that such Affiliate Transaction complies with
clause (i) in the first paragraph above, and contains terms substantially
similar to the terms of Global I Leases, Global II Leases and Global III
Leases, and any extension, amendment, replacement or renewal thereof.
 
 Limitation on Liens
 
  Under the terms of the Indenture, the Company will not, and will not permit
any Restricted Subsidiary to, create, incur, assume or suffer to exist any
Lien on any of its assets or properties of any character, or any shares of
Capital Stock or Indebtedness of any Restricted Subsidiary, except for
Permitted Liens.
 
  The Indenture will also provide that if the Company or any of its Restricted
Subsidiaries shall create, incur, assume or suffer to exist any Lien, other
than a Permitted Lien, on any assets or other property to secure Indebtedness
in violation of this covenant, the Company or such Restricted Subsidiary, as
the case may be, shall make effective provision for securing the Senior Notes
equally and ratably with such Indebtedness as to such assets or other property
for so long as such Indebtedness shall be so secured.
 
 Limitation on Modifications to Certain Documents
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to: (a) after the issuance thereof, amend or modify (or permit the amendment
or modification of) any of the terms or provisions of the Intercompany Notes
in any manner adverse to the interests of the Holders and the Indenture
Trustee under the Pledge Agreement, or forgive or reduce (except to extent
resulting from actual repayment to the Company in cash) the principal amount
of the Indebtedness evidenced thereunder, or (b) amend or modify any of the
terms or provisions of its estatutos sociales or other charter documents and,
in the case of the Restricted Subsidiaries, any lease agreement to which an
Affiliate of such Restricted Subsidiary or an Affiliate of the Company is a
party, in any manner adverse to the interests of the Holders.
 
 Limitation on Asset Sales
 
  Under the terms of the Indenture, the Company will not, and will not permit
any Restricted Subsidiary to, consummate any Asset Sale, unless (i) the
consideration received by the Company or such Restricted Subsidiary is at
least equal to the Fair Market Value of the assets sold or disposed of (as
determined in good faith by the Company's Board of Directors or if the Fair
Market Value of such assets (A) exceeds $10.0 million but is less
 
                                      98
<PAGE>
 
than $25.0 million, the Company shall receive from an independent
internationally recognized investment banking firm or independent Colombian
investment banking firm or (B) exceeds $25.0 million, the Company shall
receive from an independent internationally recognized investment banking
firm, a written opinion in customary form as to the fairness, to the Company,
of such Asset Sale) and (ii) at least 75% of the consideration received
consists of cash or Cash Equivalents.
 
  Upon the consummation of an Asset Sale, the Company may apply, or cause such
Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset
Sale within 270 days of receipt thereof either to (A) permanently prepay any
Bank Indebtedness and, in the case of any Bank Indebtedness outstanding under
a revolving credit facility, to effect a permanent reduction in the
availability under such revolving credit facility, (B) invest in property or
assets that are used in a Telecommunications Business, or the acquisition of
Capital Stock of any Person primarily engaged in a Telecommunications Business
if, as a result of such acquisition, such Person would become a Restricted
Subsidiary and such acquisition is in compliance with the "--Limitation on
Restricted Payments" covenant or (C) a combination of prepayment and
investment permitted by the foregoing clauses (A) and (B). On the 271st day
after an Asset Sale or such earlier date, if any, as the Board of Directors of
the Company or of such Restricted Subsidiary determines not to apply any
portion of the Net Cash Proceeds relating to such Asset Sale as set forth in
Clauses (A), (B) or (C) of the preceding sentence (each, a "Net Proceeds Offer
Trigger Date"), such aggregate amount of Net Cash Proceeds which have not been
applied on or before such Net Proceeds Offer Trigger Date as permitted in
clauses (A), (B) or (C) of the preceding sentence (each a "Net Proceeds Offer
Amount") shall be applied by the Company to make an offer to purchase (the
"Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not
less than 30 nor more than 45 days following the applicable Net Proceeds Offer
Trigger Date, from the Holders on a pro rata basis that amount of Senior Notes
equal to the Net Proceeds Offer Amount at a price equal to 100% of the
principal amount of the Senior Notes to be purchased, plus accrued and unpaid
interest thereon, if any, to the date of purchase; provided, however, that if
at any time any non-cash consideration received by the Company or any
Restricted Subsidiary of the Company, as the case may be, in connection with
any Asset Sale is converted into or sold or otherwise disposed of for cash
(other than interest received with respect to any such non-cash
consideration), then such conversion or disposition shall be deemed to
constitute an Asset Sale under the Indenture and the Net Cash Proceeds thereof
shall be applied in accordance with this covenant.
 
  Notwithstanding the foregoing, if a Net Proceeds Offer Amount is less than
$5.0 million, the application of the Net Cash Proceeds constituting such Net
Proceeds Offer Amount to a Net Proceeds Offer may be deferred until such time
as such Net Proceeds Offer Amount plus the aggregate amount of all Net
Proceeds Offer Amounts arising subsequent to the Net Proceeds Offer Trigger
Date relating to such initial Net Proceeds Offer Amount from all Asset Sales
by the Company and its Restricted Subsidiaries aggregates at least $5.0
million, at which time the Company shall apply all Net Cash Proceeds
constituting all Net Proceeds Offer Amounts that have been so deferred to make
a Net Proceeds Offer (the first date the aggregate of all such deferred Net
Proceeds Offer Amounts is equal to $5.0 million or more shall be deemed to be
a Net Proceeds Offer Trigger Date).
 
  Each Net Proceeds Offer will be mailed within not less than 30 nor more than
45 days following the applicable Net Proceeds Offer Trigger Date to the record
Holders as shown on the register of Holders, with a copy to the Pass Through
Trustee and the Indenture Trustee, and shall comply with the procedures set
forth in the Indenture. Upon receiving notice of the Net Proceeds Offer,
Holders may elect to tender its Senior Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. To the extent Holders properly
tender Senior Notes in an amount exceeding the Net Proceeds Offer Amount,
Senior Notes of tendering Holders will be purchased on a pro rata basis (based
on amounts tendered). A Net Proceeds Offer shall remain open for a period of
20 Business Days or such longer period as may be required by law.
 
  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder in
connection with the repurchase of Senior Notes pursuant to a Net Proceeds
Offer (whether or not such rule by its terms would be applied to such offer as
a matter of law). To the extent that the provisions of any securities laws or
regulations conflict with the "Asset Sale" provisions of the Indenture, the
Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the "Asset Sale"
provisions of the Indenture by virtue thereof.

 Conduct of Business
 
  The Indenture provides that the Company and its Restricted Subsidiaries may
not, directly or indirectly, engage in any business other than the
Telecommunications Business in Latin America; provided that in the event a
Change of Control occurs in which one or more Strategic Equity Investors gain
control of the Company this covenant shall no longer be of force or effect.
 
 Reports
 
  For so long as any of the Senior Notes remain outstanding, the Company will
file with the Indenture Trustee: (i) within 120 days after the end of each
fiscal year, (a) audited year-end consolidated financial statements prepared
in accordance with GAAP and reconciled to U.S. GAAP and (b) the information
described in Item 303 of Regulation S-K under the Securities Act, (ii) by
January 30, 1998, (a) unaudited quarterly consolidated financial statements
prepared in accordance with GAAP and reconciled to U.S. GAAP and (b) the

after the end of each of the first three fiscal quarters of each fiscal year,
(a) unaudited quarterly consolidated financial statements prepared in
accordance with GAAP and reconciled to U.S. GAAP (year to date only)
(provided, that, such quarterly financial statements and reconciliation to
U.S. GAAP shall continue to be provided for a period to be agreed to between
the Company and the Holders if 66 2/3% in principal amount of the outstanding
Senior Notes request) and (b) the information described in Item 303 of
Regulation S-K under the Securities Act, with respect to such period. Upon
qualification of the Indenture under the Trust Indenture Act, the Company
shall also comply with the provisions of Trust Indenture Act Section 314(a).
In the event that the Company is not required or shall cease to be required to
file reports with the Commission pursuant to the Exchange Act, the Company
shall nevertheless continue to file such reports with the Commission and the
Indenture Trustee. If the Indenture Trustee (at the Company's request and
expense) is to mail the foregoing information to the Holders, the Company
shall supply such information to the Indenture Trustee at least five days
prior thereto.
 
ADDITIONAL AMOUNTS
 
  The Company has covenanted in the Indenture that (A) for so long as the
Trust is required to pay any amounts in respect of the Senior Notes to the
Certificateholders, the Company will pay as additional sums on the Senior
Notes such amounts as may be (a) required so that such payments by the Trust
will not be reduced as a result of any Taxes imposed by any Taxing Authority
on payments to the Trust under the Indenture to the extent that the Trust
would have been obligated to pay Additional Amounts with respect to such
amounts if such payment had been made by the Trust to the Certificateholder
and (b) such amounts as may be necessary in order to satisfy the obligation of
the Trust to pay any (i) Additional Amounts in respect of the Certificates,
and (ii) any stamp, issue, transfer, sales, use, value-added property,
registration, documentary, enforcement or other similar taxes and other duties
(including interest and penalties) payable to any Taxing Authority in respect
of the creation, issue or offering of the Certificates or any other documents
directly related to such creation, issue or offering; and (c) such amounts as
may be required so that the payments payable by the Trust will not be reduced
as a result of any Taxes or other liabilities imposed on the Trust, except to
the extent that the Company is required to pay such Taxes pursuant to (a) or
(b) of this paragraph. See also "Description of the Guarantees--Additional
Amounts."
 
EVENTS OF DEFAULT
 
  The following events will be defined as "Events of Default" in the
Indenture:
 
    (a) default in the payment of principal of, or premium, if any, on, the
  Senior Notes when the same becomes due and payable at maturity, upon
  acceleration, redemption or otherwise;
 
    (b) default in the payment of interest on the Senior Notes when the same
  becomes due and payable and such default continues for a period of 30 days;
 
    (c) failure to perform or comply with the provisions described under "--

                                      100
<PAGE>
 
    (d) failure to comply with the covenant described under "--Consolidation,
  Merger and Sale of Assets;"
 
    (e) the Company defaults in the performance of or breaches any other
  covenant or agreement of the Company in the Indenture, the Senior Notes or
  the Escrow and Disbursement Agreement and such default or breach continues
  for a period of 30 consecutive days after written notice by the Indenture
  Trustee or the Holders of 25% or more in aggregate principal amount of the
  Senior Notes outstanding (other than those referred to in (a), (b), (c) or
  (d));
 
    (f) there occurs with respect to (A) any issue or issues of Indebtedness
  (other than Intercompany Notes) of the Company or any Subsidiary having an
  outstanding principal amount of $5 million or more in the aggregate for all
  such issues of all such Persons or (B) any Intercompany Note of any
  Restricted Subsidiary, in each case, whether such Indebtedness now exists
  or shall hereafter be created, (I) an event of default that has caused the
  holder thereof to declare such Indebtedness to be due and payable prior to
  its final Stated Maturity and such Indebtedness has not been discharged in
  full or such acceleration has not been rescinded or annulled within 30 days
  following such acceleration and/or (II) the failure to make a principal
  payment at the final Stated Maturity and such defaulted payment shall not
  have been made, waived or extended within 30 days of such payment default
  or any longer grace period provided for in such Indebtedness;
 
    (g) one or more final judgments rendered against the Company or any of
  its Subsidiaries (other than any judgment as to which a reputable insurance
  or bonding company has accepted full liability in writing) aggregating in
  excess of $5.0 million which judgments are not stayed within 60 days after
  their entry;
 
    (h) certain events of bankruptcy, liquidation, insolvency, "concordato",
  reorganization or administration affecting the Company or any Subsidiary;
 
    (i) there occurs with respect to the Global I Purchase Agreement, the
  Global II Purchase Agreement, the purchase agreements to be entered into in
  connection with the Global III Leases, or any future Global arrangements
  permitted under the Indenture an event of default that has caused Siemens
  to declare Global's Obligations under such purchase agreements to be due
  and payable prior to such Obligations' Stated Maturity and (A) such
  Obligations have not been discharged in full, or (B) such acceleration has
  not been rescinded or annulled within 10 days following such acceleration;
 
    (j) failure by Global to perform or comply with the Global Undertaking
  Letter, or Global rejects being bound by the terms of the Global
  Undertaking Letter; and
 
    (k) repudiation by the Company of its obligations under the Escrow and
  Disbursement Agreement for any reason.
 
  If an Event of Default (other than an Event of Default specified in clauses
(h) above that occurs with respect to the Company and (i) above) occurs and is
continuing under the Indenture, the Indenture Trustee or the Holders of at
least 25% in aggregate principal amount of the Senior Notes outstanding by
written notice to the Company (and to the Indenture Trustee if such notice is
given by the Holders), may declare the Senior Notes outstanding to be
immediately due and payable at 100% of the unpaid principal thereof plus
accrued and unpaid interest thereon, if any. Upon a declaration of
acceleration, such principal of, premium, if any, and accrued interest shall
be immediately due and payable. If an Event of Default specified in clauses
(h) or (i) above occurs with respect to the Company or an Event of Default
specified in clause (j) above occurs with respect to Global, the Senior Notes
then outstanding shall ipso facto become and be immediately due and payable at
100% of the principal amount thereof plus accrued and unpaid interest thereon,
if any, to the date of such Event of Default, without any declaration or other
act on the part of the Indenture Trustee or any Holder. At any time after a
declaration of acceleration, but before a judgment or decree for the payment
of money due has been obtained by the Indenture Trustee, the Holders of at
least a majority in principal amount of the outstanding Senior Notes by
written notice to the Company and to the Indenture Trustee, may waive all past
defaults and rescind and annul a declaration of acceleration and its
consequences (i) if the rescission would not conflict with any judgment or
decree; (ii) if all existing Events of Default have been cured or waived
except non-payment of principal or interest that has become due solely because
of the acceleration; (iii) to the extent the payment of such interest is
lawful, interest
 
                                      101
<PAGE>
 
on overdue installments of interest and overdue principal, which has become
due otherwise than by such declaration of acceleration, has been paid; (iv) if
the Company has paid the Indenture Trustee its reasonable compensation and
reimbursed the Indenture Trustee for its expenses, disbursements and advances;
and (v) in the event of the cure or waiver of an Event of Default specified in
clause (h) above, the Indenture Trustee shall received an Officers'
Certificate and an Opinion of Counsel that such Event of Default has been
cured or waived. For information as to the waiver of defaults, see "--
Modification and Waiver."
 
  The Holders of at least a majority in aggregate principal amount of the
outstanding Senior Notes may direct the time, method and place of conducting
any proceeding for any remedy available to the Indenture Trustee or exercising
any trust or power conferred on the Indenture Trustee. However, the Indenture
Trustee may refuse to follow any direction that conflicts with law or the
Indenture, that may involve the Indenture Trustee in personal liability, or
that the Indenture Trustee determines may be unduly prejudicial to the rights
of Holders of Senior Notes not joining in the giving of such direction and may
take any other action it deems proper that is not inconsistent with any such
direction received from Holders of Senior Notes. A Holder may not pursue any
remedy with respect to the Indenture or the Senior Notes unless: (i) the
Holder gives the Indenture Trustee written notice of a continuing Event of
Default; (ii) the Holders of at least 25% in aggregate principal amount of
outstanding Senior Notes make a written request to the Indenture Trustee to
pursue the remedy; (iii) such Holder or Holders offer the Indenture Trustee
indemnity satisfactory to the Indenture Trustee against any loss, liability or
expense; (iv) the Indenture Trustee does not comply with the request within 15
days after receipt of the request and the offer of indemnity; and (v) during
such 15-day period, the Holders of a majority in aggregate principal amount of
the outstanding Senior Notes do not give the Indenture Trustee a direction
that is inconsistent with the request. However, such limitations do not apply
to the right of any Holder of a Senior Note to receive payment of the
principal of, premium, if any, or interest on, such Senior Note or to bring
suit for the enforcement of any such payment, on or after the due date
expressed in the Senior Notes, which right shall not be impaired or affected
without the consent of the Holder.
 
  The Indenture requires certain officers of the Company to certify, on or
before a date not more than 120 days after the end of each fiscal year, that a
review has been conducted of the activities of the Company and its Restricted
Subsidiaries, and of the Company's and its Subsidiaries' performance under the
Indenture or the Escrow and Disbursement Agreement, and that the Company has
fulfilled all obligations under the Indenture or the Escrow and Disbursement
Agreement, or, if there has been a default in the fulfillment of any such
obligation, specifying each such default and the nature and status thereof.
The Company will also be obligated to notify the Indenture Trustee of any
default or defaults in the performance of any covenants or agreements under
the Indenture or the Escrow and Disbursement Agreement.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Company shall not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its
property or assets (as an entirety or substantially an entirety in one
transaction or a series of related transactions) to, any Person or permit any
Person to merge with or into the Company (other than a consolidation or merger
with or into a Restricted Subsidiary with a positive net worth where minority
shareholders of Restricted Subsidiaries receive only stock of the surviving
entity; provided that, in connection with any such merger or consolidation,
clauses (i) and (iv) below are complied with and no consideration (other than
Common Stock in the surviving Person or the Company) shall be issued or
distributed to the shareholders of the Company) unless: (i) the Company shall
be the surviving Person, or the Person (if other than the Company) formed by
such consolidation or into which the Company is merged or that acquired or
leased such property and assets of the Company shall be a corporation
organized and validly existing under the laws of Colombia or the United States
of America, any State thereof or the District of Columbia, and shall expressly
assume, by a supplemental indenture, executed and delivered to the Indenture
Trustee, all of the obligations of the Company under the Senior Notes and the
Indenture; (ii) immediately after giving effect to such transaction, no
Default or Event of Default shall have occurred and be continuing; (iii)
immediately after giving effect to such transaction on a pro forma basis, the
Company, or any Person becoming the successor obligor of the Senior Notes,
could incur at least $1.00 of Indebtedness under the first paragraph of clause
(a) of the "--Limitation on Indebtedness" covenant (without reliance upon any
of the exceptions in (a)(i) through (xi)
 
                                      102
<PAGE>
 
under "--Limitation on Indebtedness"); and (iv) the Company delivers to the
Indenture Trustee an Officers' Certificate (attaching, if applicable, the
arithmetic computations to demonstrate compliance with clause (iii)) and
opinion of counsel, in each case stating that such consolidation, merger or
transfer and such supplemental indenture complies with this provision and that
all conditions precedent provided for herein relating to such transaction have
been complied with.
 
  The Indenture provides that upon any consolidation, combination or merger or
any transfer of all or substantially all of the assets of the Company in
accordance with the foregoing, the surviving entity shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
the Indenture and the Senior Notes with the same effect as if such surviving
entity had been named as such; provided that solely for purposes of computing
amounts described in clause (C) of the first paragraph of the covenant "--
Limitation on Restricted Payments" above, any such surviving entity to the
Company shall only be deemed to have succeeded to and be substituted for the
Company with respect to periods subsequent to the effective time of such
merger, consolidation, combination or transfer of assets.
 
BANKRUPTCY ("CONCORDATO")
 
  Under Colombian law, the procedure for reorganization differs from that in
the United States. Under Law 222/1995, upon admittance of the Company to the
concordato proceeding, the Company cannot make any payment or settle any of
its obligations (including the Senior Notes) 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, in
which case the Company enters immediately into mandate liquidation 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 creditors are 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.
 
SATISFACTION AND DISCHARGE
 
  The Indenture will cease to be of further effect, and the Indenture Trustee,
on demand of and at the expense of the Company, will execute proper
instruments acknowledging satisfaction and discharge of the Indenture, when
(1) either (a) the Company shall have irrevocably paid in full all Guaranteed
Obligations (as such term is defined in the Certificate Guarantee) to the
Guarantee Trustee (as such term is defined in the Certificate Guarantee)
pursuant to the terms of the Certificate Guarantee; or (b) all Senior Notes
theretofore authenticated and issued (other than (i) Senior Notes which have
been destroyed, lost or stolen and which have been replaced or paid and (ii)
Senior Notes for whose payment money has theretofore been deposited in trust
or segregated and held in trust by the Company and thereafter repaid to the
Indenture Trustee or discharged from such trust) have been delivered to the
Indenture Trustee for cancellation; or (c) all such Senior Notes not
theretofore delivered to the Indenture Trustee for cancellation (i) have
become due and payable; or (ii) will become due and payable within one year,
and the Company, in the case of (c)(i) or (ii) above, has deposited or caused
to be deposited with the Indenture Trustee as trust funds in trust an amount
sufficient to pay and discharge the entire indebtedness on such Senior Notes
not theretofore delivered to the Indenture Trustee for cancellation, for
principal of, premium, if any, and interest on the Senior Notes to the date of
such deposit (in the case of Senior Notes which have become due and payable)
together with irrevocable instructions from the Company directing the
Indenture Trustee to apply such funds to the payment thereof at maturity or
redemption, 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 Indenture 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 the Indenture have been complied
with.
 
                                      103
<PAGE>
 
  Notwithstanding the satisfaction and discharge of the Indenture, the
obligations of the Company to the Indenture Trustee with respect to
compensation, indemnification and reimbursement, the obligations of the
Indenture Trustee to any authenticating agent, registrar, co-registrar, paying
agent or transfer agent under the Indenture and, if money shall have been
deposited with the Indenture Trustee pursuant to subclause (b) of clause (1)
above, the obligations of the Indenture Trustee with respect to notices of
default under the Indenture shall survive.
 
AMENDMENT SUPPLEMENT AND WAIVER
 
 Without Consent of Holders of Notes
 
  From time to time, the Company and the Indenture Trustee, without the
consent of the Holders of the Senior Notes, may amend the Indenture for the
following purposes, so long as such change does not adversely affect the
rights of any of the Holders. The Indenture Trustee will be entitled to rely
on such evidence as it deems appropriate, including, without limitation,
solely on an Opinion of Counsel that such change does not adversely affect the
rights of any Holder, in executing any supplemental indenture.
 
  Notwithstanding, the provisions in the Indenture with respect to amending or
supplementing with consent of Holders of Notes, the Company and the Indenture
Trustee may amend or supplement the Indenture, the Notes or the Escrow and
Disbursement Agreement without the consent of any Holder of a Senior Note: (a)
to cure any ambiguity, defect or inconsistency; (b) to provide for
uncertificated Senior Notes in addition to or in place of certificated Senior
Notes; (c) to provide for the assumption of the Company's obligations to the
Holders of the Senior Notes in the case of a merger or consolidation; (d) to
execute and deliver any documents necessary or appropriate to release Liens on
the Escrow Account and the Refinancing Account; (e) to make any change that
would provide any additional rights or benefits to the Holders of the Senior
Notes or that does not adversely affect the legal rights hereunder of any
Holder of the Senior Notes; or (f) to comply with requirements of the
Commission in order to effect or maintain the qualification of this Indenture
under the Trust Indenture Act of 1939, as it may be amended from time to time.
 
  Upon the written request of the Company accompanied by a resolution of the
Board of Directors of the Company authorizing the execution of any such
amended or supplemental Indenture, and upon receipt by the Indenture Trustee
of the documents described in the Indenture, the Indenture Trustee shall join
with the Company in the execution of any amended or supplemental Indenture
authorized or permitted by the terms of the Indenture and to make any further
appropriate agreements and stipulations which may be therein contained, but
the Indenture Trustee shall not be obligated to enter into such amended or
supplemental Indenture which affects its own rights, duties or immunities
under the Indenture or otherwise.
 
 With Consent of Holders of Notes
 
  The Company and the Indenture Trustee may amend or supplement the Indenture,
the Senior Notes or the Escrow and Disbursement Agreement or any amended or
supplemental Indenture with the written consent of the Holders of Senior Notes
of not less than a majority in aggregate principal amount of the Senior Notes
then outstanding, and any existing Default and its consequences or compliance
with any provision of the Indenture, the Senior Notes or the Escrow and
Disbursement Agreement may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Senior Notes.
 
  Upon the request of the Company accompanied by a resolution of the Board of
Directors of the Company authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Indenture Trustee of
evidence satisfactory to the Indenture Trustee of the consent of the Holders
of Senior Notes as aforesaid, and upon receipt by the Indenture Trustee of the
documents described in the Indenture Trustee shall join with the Company in
the execution of such amended or supplemental Indenture unless such amended or
supplemental Indenture affects the Indenture Trustee's own rights, duties or
immunities under the Indenture or otherwise, in which case the Indenture
Trustee may in its discretion, but shall not be obligated to, enter into such
amended or supplemental Indenture.
 
                                      104
<PAGE>
 
  It shall not be necessary for the consent of the Holders of Senior Notes to
approve the particular form of any proposed amendment or waiver, but it shall
be sufficient if such consent approves the substance thereof.
 
  After such amendment, supplement or waiver becomes effective, the Company
shall mail to the Holders of Senior Notes affected thereby a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to
mail such amended notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to provisions in the Indenture, the Holders of a
majority in aggregate principal amount of the Senior Notes then outstanding
may waive compliance in a particular instance by the Company with any
provision of the Indenture or the Senior Notes. However, without the consent
of each Holder affected thereby, an amendment or waiver may not (with respect
to any Senior Notes held by a non-consenting Holder of Senior Notes); (a)
reduce the principal amount of Senior Notes whose Holders must consent to an
amendment, supplement or waiver; (b) reduce the principal of or change or have
the effect of changing the fixed maturity of any Senior Note or change the
date on which any Senior Note may be subject to redemption or repurchase, or
reduce the redemption or repurchase price thereof; (c) reduce the rate of or
change or have the effect of changing the time for payment of interest,
including defaulted interest, on any Senior Notes; (d) waive a Default or
Event of Default in the payment of principal of or premium, if any, or
interest on the Senior Notes (except a rescission of acceleration of the
Senior Notes by the Holders of at least a majority in aggregate principal
amount of the Senior Notes and a waiver of the payment default relating solely
to the principal or interest that has become due solely because of the
acceleration); (e) make any Senior Note payable in money other than that
stated in the Senior Notes; (f) make any change in the provisions of the
Indenture relating to waivers of past Defaults or the rights of Holders of
Senior Notes to receive payments of principal of or interest on the Senior

the continuance of a Default, the Indenture Trustee will not be liable, except
for the performance of such duties as are specifically set forth in such
Indenture. If an Event of Default has occurred and is continuing, the
Indenture Trustee will use the same degree of care and skill in its exercise

reference therein, contain limitations on the rights of the Indenture 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 Indenture Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest, it must eliminate such conflict within 90 day, apply to
the Commission for permission to continue as trustee or resign.

                                   TAXATION
 
  The following is a discussion of certain Colombian and United States federal
income tax considerations associated with the exchange of Original
Certificates for Exchange Certificates and the ownership and disposition of
the Exchange Certificates by Exchange Certificateholders who acquire the
Exchange Certificates pursuant to the Exchange Offer. This discussion is based
upon existing Colombian and United States federal income tax law, which is
subject to change, possibly retroactively. This discussion does not describe
all aspects of Colombian or United States federal income taxation, but only
summarizes the material Colombian income tax consequences to Non-Colombian
Holders (as defined herein) and the material United States federal income tax
consequences to United States Holders (as defined herein) of exchange for,
ownership of and disposition of Exchange Certificates.
 
  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. These laws and practices are subject to changes
subsequent to the date of this Prospectus and any such changes may be
retroactive.
 
  As used herein in referring to Certificateholders, a "Non-Colombian Holder"
means: (i) a natural person who is neither a citizen nor a resident of
Colombia; (ii) a company or other legal entity that is not organized under the
laws of Colombia or any political subdivision thereof; and (iii) any other
person that is not subject to Colombian income tax on a net income basis in
respect of the Certificates.
 
  As used herein in referring to Certificateholders, a "United States Holder"
means: (i) a natural person who is either a citizen or a resident of the
United States; (ii) a corporation, partnership or other legal entity organized
under the laws of the United States, any State thereof or the District of
Columbia; (iii) an estate the income of which is subject to United States
federal income taxation regardless of its source; (iv) a trust (a) the
administration over which a United States court can exercise primary
supervision and (b) over which one or more United States persons have the
authority to control all substantial decisions; and (v) a person that for any
other reason is subject to United States federal income tax on a net income
basis in respect of the Exchange Certificates.
 
COLOMBIA
 
  The consummation of the Exchange Offer will not be a taxable event for
Colombian tax purposes to the "Non-Colombian Holders."
 
UNITED STATES
 
 In General
 
  Under current law, the Trust will be classified as a grantor trust (and not
as an association taxable as a corporation) for United States federal income
tax purposes and each Exchange Certificateholder will be treated as the owner
of a pro rata undivided interest in the Senior Notes and any other property
owned by the Trust. Each Exchange Certificateholder will be required to report
on its United States federal income tax return its pro rata share of the
income from the Senior Notes and any other property owned by the Trust, in
accordance with the Exchange Certificateholder's method of accounting.
 
  The following deals only with Exchange Certificates that are held as capital
assets by certain United States Holders, and does not address special aspects
of United States federal income taxation that may be applicable to Exchange
Certificateholders that are subject to special tax rules with respect to the
Exchange Certificates, such as dealers or traders in securities or currencies,
financial institutions, insurance companies, tax-exempt entities, persons
holding Exchange Certificates as a part of a "hedging," "conversion" or
"integrated" transaction or as a position in a straddle, or persons whose
"functional currency" is not the U.S. dollar. Moreover, this summary does not
address the federal United States income tax treatment of Exchange
Certificateholders that do not acquire Exchange Certificates in exchange for
Original Certificates that were acquired as part of the initial
 
                                      118
<PAGE>
 
distribution at the initial issue price. 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 United States
federal income tax consequences different from those discussed below. This
summary does not discuss the potential impact of state and local taxes on an
Exchange Certificateholder by reason of its exchange of an Original
Certificate for an Exchange Certificate or its ownership of an Exchange
Certificate.
 
 The Exchange
 
  The exchange of Original Certificates for Exchange Certificates pursuant to
the Exchange Offer will not be a taxable event for United States federal
income tax purposes. Accordingly, an Exchange Certificateholder receiving
Exchange Certificates pursuant to the terms of the Exchange Offer will have
the same adjusted tax basis and holding period in Exchange Certificates, for
United States federal income tax purposes, as such Original Certificateholder
had in the Original Certificates tendered in exchange therefor.
 
 Reporting of Interest Income
 
  Each United States Holder of an Exchange Certificate will be required to
report interest (including any Additional Amounts) with respect to such
Exchange Certificate on its United States federal income tax return when such
interest is received or accrued by the Exchange Certificateholder, depending
upon its method of accounting. Such interest will be considered "foreign
source income" and, in general, "passive income" and, in the case of certain
United States Holders, "financial services income," for purposes of
calculating the Exchange Certificateholder's limitation on foreign tax
credits. In the case of an Exchange Certificateholder other than a
corporation, such interest income will, in general, also constitute
"investment income" for purposes of determining the deduction allowable for
investment interest.
 
  In the event that Colombian income or remittance taxes are withheld with
respect to a payment by the Trust to a United States Holder, such Exchange
Certificateholder may deduct the amount of such taxes from its income, or,
alternatively, may, subject to generally applicable limitations, elect to
credit the amount of such taxes against its United States tax liability under
the foreign tax credit provisions of the Internal Revenue Code.
 
  Payments of interest on an Exchange Certificate to a non-United States
Holder generally will not be subject to United States federal income tax,
provided that the Exchange Certificateholder provides the Pass Through Trustee
with the appropriate certificate to establish exemption from United States
withholding tax.
 
 Sale, Exchange or Retirement
 
  Upon the sale, exchange or retirement of an Exchange Certificate, a United
States Holder will recognize taxable gain or loss equal to the difference, if
any, between the amount realized on the sale, exchange or retirement and the
United States Holder's adjusted tax basis in such Certificate. A United States
Holder's adjusted tax basis in an Exchange Certificate generally will equal
the cost of the Original Certificate to the United States Holder of the
Original Certificate for which such Exchange Certificate was exchanged. Such
gain or loss generally will be capital gain or loss (except to the extent
attributable to accrued but unpaid interest that has not been included in
income, which will be taxable as ordinary income), and will be long-term
capital gain or loss if the Exchange Certificate has been held for more than
one year at the time of such sale, exchange or retirement, which holding
period will include the holding period of the Original Certificate. Under
legislation enacted in 1997, the top net capital gain tax rate for individual
taxpayers has been lowered from 28% maximum rate to 20% for property held for
more than 18 months (but remains at a maximum rate of 28% for property held
for more than one year, but not more than 18 months). The maximum net capital
gain tax rate for corporate taxpayers remains at 35%. Any gain realized on a
sale, exchange or retirement of an Exchange Certificate by a United States
Holder generally will be treated as United States source income.
 
  Any gain realized by a non-United States Holder upon the sale, exchange or
retirement of an Exchange Certificate generally will not be subject to United
States federal income tax.

 United States Backup Withholding Tax and Information Reporting
 
  A 31% backup withholding tax and information reporting requirements apply to
certain payments of principal of, and interest on, an obligation and to
proceeds of the sale or redemption of an obligation, to certain noncorporate
United States Holders. The payor will be required to withhold 31% of any such
payment within the United States on an Exchange Certificate to a United States
Holder (other than an "exempt recipient," such as a corporation) if such
United States Holder fails to furnish its correct taxpayer identification
number or otherwise fails to comply with, or establish an exemption from, such
backup withholding requirements. Payments of principal and interest to a non-
United States Holder will not be subject to backup withholding tax and
information reporting requirements if an appropriate certification is provided
by the Certificateholder to the payor and the payor does not have actual
knowledge that such certification is false.
 
  Any such withheld amounts are allowed as a credit against the Exchange
Certificateholder's United States federal income tax liability and may entitle
the Exchange Certificateholder to a refund provided the required information
is furnished to the IRS. In addition, certain penalties may be imposed by the
IRS on an Exchange Certificateholder who is required to supply information but
fails to do so or does so in an improper manner.
 
  PROSPECTIVE EXCHANGE CERTIFICATEHOLDERS OF THE EXCHANGE CERTIFICATES ARE
URGED TO CONSULT THEIR TAX ADVISORS CONCERNING THE PARTICULAR TAX CONSEQUENCES
OF EXCHANGING ORIGINAL CERTIFICATES FOR THE EXCHANGE CERTIFICATES, INCLUDING
THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN INCOME AND OTHER
TAX LAWS.
 
                         CERTAIN ERISA CONSIDERATIONS
 
  A fiduciary of an employee benefit plan subject to Title I of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or a plan
subject to Section 4975 of the Internal Revenue Code, including an entity
whose underlying assets are deemed to include assets of such an employee
benefit plan or plan (collectively, an "employee benefit plan"), considering
the purchase of Exchange Certificates must determine that the purchase of the
Exchange Certificates is consistent with its fiduciary duties under Title I of
ERISA and does not result in a non-exempt prohibited transaction under Section
406 of ERISA or Section 4975 of the Internal Revenue Code. "Prohibited
transactions" within the meaning of ERISA and Section 4975 of the Internal
Revenue Code may result if the Exchange Certificates are acquired by an entity
using the assets of an employee benefit plan with respect to which the Company
or certain of its affiliates is a "party in interest" or "disqualified
person", as defined in ERISA and Section 4975 of the Internal Revenue Code,
respectively, unless the Exchange Certificates are acquired pursuant to an
applicable exemption. In addition, under certain circumstances, investments in
the Exchange Certificates by employee benefit plans might result in assets of
the Trust being deemed to constitute "plan assets" subject to the regulatory
restrictions of ERISA. The level of investment by employee benefit plans in
the Exchange Certificates will not be monitored or restricted for purposes of
determining whether the assets of the Trust may be deemed to constitute such
"plan assets" or avoiding such status. In light of the foregoing
considerations, any employee benefit plan or other entity subject to Title I
of ERISA or Section 4975 of the Internal Revenue Code proposing to acquire the
Exchange Certificates should consult with legal counsel.

             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, as amended by
subsequent regulations, particularly Decree 1295 of 1996 (the "Foreign
Investment Statute") of the CONPES, and Resolution 21 of 1993 ("Resolution
21"), as amended by several resolutions issued by the Central Bank. The
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 with the exception of
defense, national security, the processing, disposal, and discharge of toxic,
hazardous, or radioactive waste not produced in Colombia, and real estate
companies; and (iii) automatic procedures: except in a limited number of
cases, foreign investors need not follow any special authorization procedure
to invest in Colombia.
 
  Under Colombian law there are three types of foreign capital investment.
First, there is direct investment, which is defined as any contribution (i.e.,
cash and debt capitalization) made by a foreigner into the capital of an
existing or newly formed company in Colombia. Second, there are investments
involving any acts or contracts whereby a foreign investor makes a
contribution to a company without taking an equity position; provided that the
income derived by the foreign investor depends on the profits generated by the
Company, and third, portfolio investment, which is made through a foreign
capital investment fund for the acquisition of shares and other securities
traded on Colombian stock exchanges.
 
  Resolution 21 established two distinct foreign exchange markets: (i) the
formal foreign exchange market, which is conducted through authorized
financial intermediaries (each an "Authorized Intermediary") and is subject to
the procedures established by Resolution 21, as amended, which requires
certain specified transactions to be carried out through such Authorized
Intermediaries; and (ii) the free market, which is available for all
transactions not required to be conducted through Authorized Intermediaries,
including the exchange of foreign currency relating to professional services,
donations and sales of goods and services to tourists.
 
  Since October 1991, exchange rates have been freely set by the market.
 
  External Resolution No. 5 of 1997 of the Central Bank (the "Resolution"),
dated May 20, 1997, introduced fundamental changes to the regulation of
foreign indebtedness in Colombia.
 
  From May 20, 1997 until the law is modified or repealed, Colombian residents
who obtain credits denominated in foreign currencies must make a deposit with
the Central Bank, prior to each disbursement of funds. The requirement applies
to both private and public entities. The deposit must be for 30% of the value
of the funds to be disbursed, converted into Colombian pesos at the
Representative Market Rate on the date of the conversion. The term of the
deposit required is 18 months. The deposit requirement applies without regard
to the term of the credit, with limited exceptions. After 18 months, the
deposit will be returned at its nominal value in Colombian pesos, in other
words, without interest or adjustment for devaluation.
 
  It is no longer necessary to register foreign credit agreements with the
Central Bank prior to disbursement. Instead, one must provide proof of having
made the required deposit to the Central Bank. The following credit operations
are exempted from the deposit requirement: (i) credits in foreign currency
intended to finance investment by Colombians outside of Colombia, or for
personal expenses using credit cards; (ii) credits in foreign currency granted
to finance exports, with a term of one year or less, by Authorized
Intermediaries using funds from BANCOLDEX (the Colombian Government Foreign
Trade Bank), up to a maximum limit of $550,000 or the equivalent in other
currencies; (iii) credit operations entered into by Authorized Intermediaries
with financial institutions outside of Colombia, for the purpose of
implementing the operations such Authorized Intermediaries are authorized to
perform; (iv) the granting of credit in foreign currency by Colombian
residents or Authorized Intermediaries to Colombian residents who are outside
of Colombia; such credit may be granted directly or using the funds of public
agencies which provide discounts; although it is not necessary to make the
deposit in such cases, one must inform the Central Bank; (v) the import
financing of certain specified capital goods (see below); and (vi) the
financing of imports for a value of less than $5,000 or the equivalent in
other currencies.
 
                                      121
<PAGE>
 
  The import financing of certain capital goods is exempt from the deposit
requirement. The list of capital goods to which this exemption applies has
been expanded by the Resolution, and exempted goods now include all goods
categorized as "machinery" or "equipment" in lists used by the Colombian
taxation authority and by INCOMEX (a Foreign Trade Governmental Agency).
 
  Foreign credits obtained by the government of Colombia, the departments or
other territorial entities and other decentralized public agencies (except
those which are designated as foreign exchange intermediaries) are also
subject to the deposit requirement. The Resolution provides that the interest
rate on such credits may not exceed the maximum preferred interest rate in the
New York market plus 5%, or the London interbank rate for one month plus 3%.
Nevertheless, when the credit is granted by Authorized Intermediaries, the
interest rate may exceed this maximum by an amount not exceeding the
Authorized Intermediaries discount margin.
 
  The Resolution provides that credits in foreign currency may be obtained by
the placement of securities in the international capital markets, prior to
making the required deposit, so long as the credits are among those authorized
by the Resolution.
 
  Users of free trade zones who obtain financing for the purchase of
merchandise must also make the deposit whenever the value of the financing is
greater than $5,000 and the term of the financing is greater than six months
from the date of the shipment or waybill. If the financing is for the purchase
of capital goods which are exempted, the deposit is not required.
 
                             PLAN OF DISTRIBUTION
 
  Each broker-dealer that receives Exchange Certificates for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver this
Prospectus in connection with any resale of such Exchange Certificates. This
Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer who holds Original Certificates 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 Exchange
Certificates received in exchange for Original Certificates. 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    , 1998, (90 days after the date of this Prospectus), all
dealers affecting transactions in the Exchange Certificates may be required to
deliver a prospectus.
 
  The Company will not receive any proceeds from the exchange of Original
Certificates for Exchange Certificates by broker-dealers. Exchange
Certificates 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 Exchange Certificates 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 Exchange Certificates. Any
broker-dealer that resells Exchange Certificates that were received by it for
its own account pursuant to the Exchange Offer and any person that
participates in the distribution of such Exchange Certificates may be deemed
an "underwriter" within the meaning of the Securities Act and any profit on
any such resale of Exchange Certificates 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.

                 ENFORCEMENT OF FOREIGN JUDGMENTS IN COLOMBIA
 
  The courts of Colombia give effect to and enforce judgments of non-Colombian
courts through a process known as exequatur provided under Colombian law,
subject to the provisions of Articles 693 through 695 of the Colombian Code of
Civil Procedure. Such articles provide for enforcement by Colombian courts of
foreign judgments that are obtained without fraud and rendered after due
notice, provided that either (i) Colombia and the country where the foreign
judgment has been issued are parties to a treaty which recognizes the
enforceability of foreign judgments; or (ii) 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 (A) does not
relate to "in rem" rights vested in assets that were located in Colombia at
the time the suit was filed; (B) does not contravene any public policy laws or
regulations of Colombia, other than those governing judicial procedures; (C)
is a final judgment not subject to appeal in accordance with the applicable
foreign laws and an original certified copy of such judgment together with a
Spanish translation provided by an official translator, is filed with the
court; (D) does not refer to any matter upon which Colombian courts have
exclusive jurisdiction; (E) does not refer to any matter subject to a lawsuit
presently ongoing in Colombia or already decided by any court of Colombia; (F)
was obtained upon compliance with the applicable foreign laws relating to
service of process to the defendant, which compliance is presumed if the
judgment is final; and (G) is 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. The Company has been advised by Cavelier Abogados 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: (A)
evidence that a court in the State of Florida had accepted the validity of a
Colombian judgment in a certain case; and (B) 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 Exchange
Certificates or the Certificate Guarantee, 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 Cavelier Abogados 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.

                         BOOK-ENTRY; DELIVERY AND FORM
 
GENERAL
 
  The Original Certificates offered and sold in reliance on Regulation S under
the Securities Act were initially represented by a single, permanent Global
Certificate in definitive, fully registered book-entry form (the "Regulation S
Global Certificate") which was registered in the name of a nominee of DTC and
deposited on behalf of the purchasers of the Original Certificates 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 Original
Certificates 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 Certificate in definitive, fully registered book-
entry form (the "Rule 144A Global Certificate," and, together with the
Regulation S Global Certificate, the "Original Global Certificates") which was
registered in the name of a nominee of DTC and deposited on behalf of
purchasers of the Original Certificates 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. Except as set forth
below, the Exchange Certificates issued pursuant to the Exchange Offer will be
issued in global form (the "Exchange Global Certificates," and together with
the Original Global Certificates, the "Global Certificates").
 
GLOBAL CERTIFICATES
 
  Upon the issuance of the Exchange Global Certificates, DTC or its custodian
will credit, on its internal system, the respective principal amount of the
individual beneficial interests represented by such Exchange Global
Certificate 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 an Exchange Global Certificate 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 Exchange Global Certificates 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
Certificate, DTC or such nominee, as the case may be, will be considered the
absolute owner or holder of the Certificates represented by such Global
Certificate for all purposes under the Indenture and the Certificates, and the
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
Certificate. Owners of beneficial interests in a Global Certificate will not
be considered to be the owners or holders of any Certificates under the
Indenture or the Certificates.
 
  In addition, no beneficial owner of an interest in a Global Certificate 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 Certificate 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 Certificate. Neither the Company nor the Pass Through
Trustee 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 Certificates 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 Certificate, 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 Certificate
 
                                      124
<PAGE>
 
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
Certificate held through such Agent Members will 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 Certificateholder only at the direction of one or more Agent
Members to whose account the DTC interests in the Global Certificates is
credited and only in respect of such portion of the aggregate principal amount
of Certificates 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 Certificates 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 nor the Pass Through Trustee 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 CERTIFICATES
 
  Interests in a Global Certificate will be exchangeable or transferable, as
the case may be, for Exchange Certificates issued in the form of registered
definitive certificates ("Certificated Certificates") if (i) DTC notifies the
Company that it is unwilling or unable to continue as depositary for such
Global Certificates, 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 Exchange Certificates and Exchange Certificateholders who
hold more than 25% in aggregate principal amount of the Exchange Certificates
at the time outstanding represented by the Global Certificates 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 Certificates
is no longer required. Upon the occurrence of any of the events described in
the preceding sentence, the Company will cause the appropriate Certificated
Certificates to be delivered.

                 GLOSSARY OF CERTAIN TELECOMMUNICATIONS TERMS
 
  The following is a glossary of certain telecommunications terms appearing
elsewhere in this Prospectus.
 
  Access Charges: The fees paid by IXCs to LECs for originating and
terminating long distance telephone calls on their local networks.
 
  AIX Operating System: Refers to IBM's version of the UNIX operating system
to be used in conjunction with Transtel's Internet and voice mail platform.
 
  ATM (Asynchronous Transfer Mode): A recently commercialized switching and
transmission technology that is one of a general class of packet technologies
that relay traffic by way of an address contained within the first five bits
of a standard fifty-three bit-long packet or cell. ATM switching was
specifically developed to allow switching and transmission of mixed voice,
data and video (sometimes referred to as "multimedia" information) at varying
rates. The ATM format can be used by many different information systems,
including LANs.
 
  Broadband: Broadband communications systems can transmit large quantities of
voice, data and video by way of digital or analog signals. Examples of
broadband communications systems include DS-3 fiber-optic systems, which can
transmit 672 simultaneous voice conversations, or a broadcast television
station that transmits high-resolution audio and video signals into the home.
Broadband connectivity is also an essential element for interactive multimedia
applications.
 
  CDMA (Code Division Multiple Access): A digital multiplexing scheme for
grouping/ungrouping numerous channels into a higher speed channel through code
division.
 
  Central Offices: The switching centers or central switching facilities of
the LECs.
 
  Centrex: Centrex is a service that offers features similar to those of a
Private Branch Exchange (PBX), except the equipment is located at the
carrier's premises and not at the premises of the customer. These features
include direct dialing within a given phone system, direct dialing of incoming
telephone calls, and automatic identification of outbound telephone calls.
This is a value-added service that carriers can provide to a wide range of
customers who do not have the size or the funds to support their own on-site
PBX.
 
  DID (Direct Inward Dialing): Central Office service allowing for calls to be
made directly to the extension of a customer's PBX, without having to go
through an operator.
 
  Digital: A method of storing, processing and transmitting information
through the use of distinct electronic or optical pulses that represent the
binary code digits 0 and 1. Digital transmission and switching technologies
employ a sequence of these pulses to represent information as opposed to the
continuously variable analog signal. Digital transmission and switching
technologies offer a threefold improvement in speed and capacity over analog
techniques, allowing much more efficient and cost-effective transmission of
voice, video and data.
 
  DS-O, E-1, E-3: Standard telecommunications industry digital signal formats,
which are distinguishable by bit rate (the number of binary digits (0 and 1)
transmitted per second). DS-O service has a bit rate of 64 kilobits per
second. E-1 service has a bit rate of 2 megabits per second and E-3 service
has a bit rate of 34 megabits per second.
 
  EWSD: Brand name for Siemens digital switching system used in both private
and public telecommunications networks.
 
  Fiber Optics: Fiber-optic cable is the medium of choice for the
telecommunications and cable industries. Fiber is immune to electrical
interference and environmental factors that affect copper wiring and satellite
 
                                      127
<PAGE>
 
transmission. Fiber-optic technology involves sending laser light pulses
across glass strands in order to transmit digital information. A strand of
fiber-optic cable is as thick as a human hair yet has significantly greater
bandwidth capacity than copper cable, which is many times greater in size.
 
  Fiber-Optic Ring Network: The Company has designed its networks in ring
configuration in order to ensure that, if one segment of a network is damaged
or cut, the traffic is simply re-routed and sent to its destination in the
opposite direction. The Company uses a "self-healing" optical fiber-ring
architecture in its networks.
 
  Frame Relay: Frame relay is a high-speed data packet switching service used
to transmit data between computers. Frame Relay supports data units of
variable lengths at access speeds ranging from 56 kilobits to 1.5 megabits.
This service is ideal for connecting LANs, but is not appropriate for voice
and video applications due to the variable delays that can occur. Frame Relay
was designed to operate at higher speeds on modern fiber-optic networks.
 
  HDSL (High Bit Rate Digital Subscriber Line): A modern technology typically
used for establishing T1/E1 trunk facilities between the Central Office and
the subscriber over copper cable facilities. HDSL modems utilize only a few
copper pairs to digitally transmit a large number of circuits.
 
  IBM's Netview: A network management system for information systems which
monitors and controls the physical network elements including, among other
things, routers, access servers, bridges, hubs and servers.
 
  IBM RS/6000: A scaleable hardware platform group based on open systems
architecture used in corporate information networks worldwide. The hardware
supports IBM's Unix.
 
  IBM's Tivoli: A family of products (registered trademark of IBM) for network
computing management of the software and hardware elements of corporate
information networks. Examples of network management include centralized
backup, software distribution, hardware inventory management and other
functions.
 
  ISDN (Integrated Services Digital Network): A switched digital service
allowing for the transmission of voice, data and/or video signals over the
public switched telecommunications network. Colombia utilizes the
international ISDN standard which allows for Basic Rate (two by kilobit
channels and one 16 kilobit data channel) over the same copper pairs used for
traditional telephone service, or Primary Rate (30 64 kilobit channels and one
16 kilobit data channel).
 
  ISP (Internet Service Provider): An Internet service provider provides
customers with access to the Internet by linking its network directly or
through other ISPs to the Internet backbone network.
 
  IXC (Interexchange Carriers): See Long Distance Carrier.
 
  LANs (Local Area Network): Corporate node for client server applications
used for corporate communications.
 
  LEC (Local Exchange Carrier): A company providing local telephone services.
 
  Long Distance Carriers or IXCs (Interexchange Carriers): Long distance
carriers provide services between local exchanges. TELECOM is the sole
provider of these services and may offer service over its own facilities.
 
  mHz: Megahertz.
 
  Mode: An individual point of origination and termination of data on the
network transported using frame relay or similar technology.
 
                                      128
<PAGE>
 
  OSP (Outside Plant): Refers to the external network of a telecommunications
company which links subscribers to Central Office switching systems, and
Central Offices to each other. This includes the cable, splices, distribution
cabinets and terminals of both copper and fiber networks. The Outside Plant
technically ends at the cable vault of the Central Office. The rest of the
technologies in the Central Office are referred to as inside plant.
 
  PBX (Private Branch Exchange): A switching system within an office building
which allows telephone calls from outside to be routed directly to the
individual instead of through a central number. The PBX also allows for
calling within an office by way of four-digit extensions. Centrex is a service
which can simulate this service from an outside switching source, thereby
eliminating the need for a large capital expenditure on a PBX.
 
  PCS (Personal Communications Service): A type of wireless telephone system
that uses light, inexpensive handheld sets and communicates via low-power
antennas.
 
  PDH (Plesiochronous Digital Hierarchy): Refers to a transmission signaling
standard. This is a more inflexible transmission scheme which is acceptable
for point to point.
 
  POPs (Points of Presence): Locations where a long distance carrier has
installed transmission equipment in a service area that serves as, or relays
telephone calls to, a network switching center of that long distance carrier.
 
  Private Line: A private, dedicated telecommunications connection between
end-use locations (excluding long distance carrier POPs).
 
  Route Miles: The number of miles of the telecommunications path in which
fiber-optic cables are installed as it would appear on a network map.
 
  SAT (Telecommunications Administration System): Brand name of C-NIX's
software. A software subscriber data base and administration system used for
inputting new service orders, assigning new, billing, installation and a range
of other functions critical to telephone operations.
 
  SDH (Synchronous Digital Hierarchy): Refers to a transmission signaling
standard which allows for the multiplexing and demultiplexing of
telecommunications traffic at multiple points along a transmission path.
 
  SPC (Stored Program Control): Stored program control switching systems
including both earlier analog and more recent digital systems.
 
  STM (Synchronous Transfer Mode): Refers to the European signaling rates of
the SDH standard starting at STM 1 or 155 Megabits.
 
  Switch: A sophisticated computer that accepts instructions from a caller in
the form of a telephone number. Like an address on an envelope, the numbers
tell the switch where to route the call. The switch opens or closes circuits
or selects the path or circuits to be used for transmission of information.
Switching is a process of interconnecting circuits to form transmission path
between users. Switches allow local telecommunications service providers to
connect telephone calls directly to their destination, while providing
advanced features and recording connection information for future billing.
 
  Switched Traffic: Telecommunications traffic along a switched network.
 
  TDMA (Time Division Multiple Access): Refers to a multiplexing scheme for
grouping/ungrouping various circuits into higher speed facilities through the
division of these signals into digital time slots.
 
  TMN (Telecommunications Management Network): Refers to an international
standard for integrated network management of all of the physical network
elements of a public telecommunications network. TMN software systems perform
such critical functions as: fault management; traffic management; customer
administration; billing; and work force management.

                             REPUBLIC OF COLOMBIA
 
  The following information has been made public by the Republic of Colombia
and has not been prepared or independently verified by the Company or any of
its affiliates. The Company is including such information solely because it is
readily available and may be useful to a reader. Such information is not, nor

information pertains to Colombia as a whole and is not specific to the
location of the Company's business and should not be viewed as reflective of
such region. The following information should be read in conjunction with the
information set forth under "Risk Factors--Colombian Political, Economic, and
Social Risks." Investors who wish to know more about Colombia are urged to
consult the wide variety of information available from public sources.
 
OVERVIEW
 
  Since 1950, Colombia has enjoyed positive real economic growth in every year
(ranging from a low of 1.0% in 1982 to a high of 8.5% 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 22.3% between 1992 and 1996. Unlike other major Latin American
countries, Colombia did not 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.
 
  In June 1994, Ernesto Samper Pizano, former Minister of Economic Development
in the previous administration of Cesar Gaviria and a former Senator, was
elected President of Colombia. President Samper proposed a four-year national
development plan, El Salto Social (The Social Leap), which was approved by the
Congress in June 1995. El Salto Social looked to continue the economic and
political reforms of the Gaviria administration's Apertura policy, under which
the Government removed restrictions on foreign investment, eliminated import
quotas and reduced tariffs, entered into free trade agreements with regional
trading partners, reduced foreign exchange controls, granted greater
independence to the Central Bank, encouraged private sector participation in
the management of pension system assets and began a privatization program with
respect to certain state-owned companies and financial institutions. At the
same time, El Salto Social aimed to secure the benefits of these reforms for a
larger segment of the population.
 
  Under El Salto Social, the Government, among other measures, has set out to:
 
  . Increase government expenditures directed toward the social sector,
    including higher spending on health, education and job training programs
    and the implementation of the Red de Solidaridad Social (Social
    Solidarity Network), while maintaining current levels of expenditures on
    defense and justice;
 
  . Increase tax revenues by improving tax collections and reducing
    exemptions;
 
  . Improve and develop infrastructure by attracting private investment
    through privatizations and concessions;
 
  . Implement measures, together with the Central Bank, to reduce inflation,
    including reaching agreement with labor and business to restrict wage and
    price increases;
 
  . Maintain competitiveness of the exchange rate by implementing measures,
    in conjunction with the Central Bank (which is primarily responsible for
    setting the foreign exchange rate policy), to limit short-term capital
    inflows and an appreciation of the peso; and
 
  . Strengthen domestic savings by developing the domestic capital market,
    and carefully investing the proceeds from increased exports of oil in the
    international markets.

  The Colombian government believes that a continuation of nearly balanced
public sector budgets and the policies outlined above, together with projected
growth in oil exports and other factors, should contribute toward continued
moderate real GDP growth over the medium term.
 
  However, for the past two years, the fiscal deficit created by an increase
in public expenditures has resulted in an increase in interest rates from
19.46% in 1995 to 21.63% in 1996 and a slow down in the economy's growth.
 
 Geography and Population
 
  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.
 
  In 1993, according to the census conducted in that year, Colombia's
population was 35.9 million, approximately 73% of whom lived in urban areas.
Over 6.3 million people live in the metropolitan area of Bogota, the capital
of Colombia. Cali and Medellin, the second and third largest cities, have
populations of approximately 1.95 million and 1.93 million, respectively. The
most important urban centers, with the exception of Barranquilla (the largest
port city), are located in the Andes range. The population grew at a rate of
2.2% per year from 1985 through 1993, down from approximately 3.1% per year in
the 1960s.
 
 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 Partido Liberal (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 became a recognized political party at the end of the 1980s.
 
  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 narcotics-related violence, and to enhance
control and supervision over public officials.
 
 Foreign Affairs and International Organizations
 
  Colombia has diplomatic ties with 154 countries. Colombia is a member of the
United Nations, the International Monetary Fund (the "IMF") and the
International Bank for Reconstruction and Development (the "World Bank"). In
October 1995, Colombia assumed the presidency of the Group of 77 (Non-Aligned
Nations). On the regional level, Colombia is a member of the Organization of
American States, the Inter-American Development Bank (the "IDB"), the
Caribbean Development Bank, the Latin American Economic System and the Andean
Development Bank. Colombia is also party to several trade and commodity
agreements, including the Andean Pact, the Latin American Integration
Association, the Union of Banana Exporting Countries, the International Sugar
Association, the General Agreement on Tariffs and Trade ("GATT") and the World
Trade Organization.
 
  In 1992, a free-trade zone was formed with Venezuela which has increased
commercial trade and financial activity between these two neighboring
countries. Colombia also has free trade agreements with Ecuador and Bolivia,
and a free trade agreement with Chile which became effective on January 1,
1994. The Andean Pact, which is designed to create a five-nation free-trade
zone, was revived in December of 1991. Pursuant to this agreement, Colombia,
Venezuela, Peru, Ecuador and Bolivia have implemented common external tariffs
as of February 1, 1995.

ECONOMY
 
 Gross Domestic Product
 
  Traditionally, agriculture has played a large role in the Colombian economy,
accounting for an estimated 18.6% of GDP in 1996 as compared to 17.9% of GDP
for industry. In 1996, agricultural activity increased by 0.2% in real terms
(despite a decrease in coffee production of 18.5%), industrial activity
increased by 2.9%, construction increased by 0.3%, and services increased by
4.7%. Between 1992 and 1996, GDP grew at an average annual rate of 4.7%. Real
GDP growth for 1996 was 2.1%, as compared with 5.4% in 1995, mainly as a
result of the strict monetary policy implemented in late 1994 to stabilize the
growth of aggregate demand and credit.
 
  The following table sets forth the annual change in Colombia's real GDP by
sector for the periods indicated.

  In 1996, exports are estimated to have increased by 2.9%, primarily due to
increased exports of oil and its derivatives attributable to increased
production from the Cusiana oil field and higher international oil prices, as
well as to increased exports of coal. Exports in 1996 are estimated to have
totaled approximately $10.6 billion, including oil and its derivatives (27.4%
of total exports), coffee (14.9% of total exports), coal (8.3% of total
exports), nickel and gold (3.6% of total exports) and nontraditional exports
(45.8% of total exports). In 1996, the volume of exports of crude oil
increased by 3.1% and the international price of Colombian crude oil increased
by 26.8%.

  Imports (FOB) increased by 17.0% in 1995 and 1.3% in 1996, due to a lowering
of tariffs and an appreciation of the peso in real terms. In 1996, imports
(FOB) are estimated to have totaled $13.7 billion, basically unchanged from
their level in 1995. Imports (FOB) of consumer goods are estimated to have
fallen by 4.1%, while imports of raw materials and intermediate goods are
estimated to have increased by 6.2% and imports of capital goods are estimated
to have fallen by 9.0%, from 1995 to 1996. Consumer goods are estimated to

  The United States is Colombia's most important trading partner. During the
first ten months of 1996, trade between the two countries accounted for
approximately 40% of Colombia's total trade (exports and imports). During the
first ten months of 1996, Venezuela was Colombia's second largest trading
partner, accounting for a further 8.3% of total trade. A key component of the
Apertura program of reforms involved reducing trade barriers by fostering
economic integration with other countries. The Samper administration has
continued former President Gaviria's policies of promoting bilateral and
multilateral trade agreements with regional trading partners.
 
  From 1991 to 1996, growth in exports occurred mainly with countries that are
members of the Andean Pact--primarily Venezuela, Peru and Ecuador. Exports to
Venezuela have grown from $443 million in 1991 to $772 million in 1996.
Similarly, exports to Peru have grown to $610 million in 1996 from $213
million in 1991 and exports to Ecuador have grown to $420 million in 1996 from
$127 million in 1991. Imports from the Andean Pact countries have also
increased 271% from $482 million in 1991 to $1,791 million in 1996.
 
DIRECT FOREIGN INVESTMENT
 
  Foreign investment in Colombia was traditionally directed towards the oil
and mining sectors. Previously, investment in sectors such as public services
was prohibited, and investments in the financial sector were limited to no
more than 49% foreign ownership of financial institutions. As part of the
Apertura process, the Gaviria administration enacted reforms designed to make
foreign investment in Colombia more attractive, such as the
 
                                      135

adoption of a legislative framework that ensures equal treatment of foreign
and local investors and foreign access to traditionally restricted economic
sectors.

MONETARY SYSTEM AND MONETARY AGGREGATES
 
  The Central Bank was chartered in 1923. Following ratification of the new
Constitution in 1991, the Central Bank was granted greater independence from
the government in the formulation of monetary policy.
 
  Monetary and exchange rate policy is set by the Central Bank'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 expirations 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 the Central Bank, is
elected by the other six members. Unless all seven members of the Board of
Directors vote to do so, the Central Bank may not finance the government's
budget deficits, and the Central Bank is prohibited from making loans to the
private sector (except to provide liquidity to the financial system or for
intermediation of foreign indebtedness).

FOREIGN EXCHANGE RATES
 
  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
the Central Bank.
 
  In February 1994, the Central Bank instituted a mechanism, which consists of
a 15% band within which the exchange rate is allowed to fluctuate. The Central
Bank intervenes by selling or purchasing its debt securities in order to
maintain the exchange rate within the 15% band. Such a band is allowed to
depreciate by small amounts to meet an annual target devaluation rate. In
December 1994, the Central Bank narrowed the band to 14%, shifted
 
                                      137
<PAGE>
 
the band downward by 7% and increased the rate at which it devalues the band
to meet an annual target devaluation rate of 13.6% for 1995. The band was set
to reflect a projected devaluation rate, in nominal terms, of 13.6% for 1996,
and 15.0% for 1997.
 
  During the second half of 1996, the peso appreciated in relation to the
dollar, recovered its value and ended the year at the bottom of the exchange
rate band. During the first six months of 1997, the devaluation rate kept a
stable pace and the rate kept within the lower half of the band. For 1997, the
Government estimates a depreciation of the peso against the dollar of 15% in
nominal terms (a 1.3% appreciation in real terms), very similar to the
targeted depreciation of 13.6% in nominal terms for 1996.
 
INTERNATIONAL RESERVES
 
  As of December 31, 1996, net international reserves were $9.9 billion,
representing coverage of approximately nine months of imports of goods and
approximately six months of imports of goods and services. Net international
reserves increased by $1.6 billion, or 18.9%, from December 31, 1995 to
December 31, 1996.
 
  The following table shows the composition of international reserves of the
Central Bank at each of the dates indicated.

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, 1996 was
 
                                      138
<PAGE>
 
$16.4 billion. As of June 30, 1997 the total market capitalization was $19.6
billion (an increase of 34.3% from the same period in 1996, when it reached
$14.6 million).
 
  The total value of securities traded on the three Colombian stock exchanges
during 1996 was Ps36,615 billion (approximately $36.6 billion), representing
nominal growth of 42% over the value of securities traded in 1995. 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.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Transtel S.A.
 
  We have audited the accompanying consolidated balance sheets of Transtel
S.A. and its subsidiaries as of December 31, 1996 and September 30, 1997, and
the related consolidated statements of income, of changes in shareholders'
equity, of changes in financial position and of cash flows for each of the two
years in the period ended December 31, 1996 and for the nine months ended
September 30, 1997, all expressed in constant Colombian pesos of September 30,
1997 purchasing power. 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, which are substantially consistent with those in the
United States of America. 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 consolidated financial statements audited by us present
fairly, in all material respects, the financial position of Transtel S.A. and
its subsidiaries at December 31, 1996 and September 30, 1997, and the results
of their operations, the changes in their financial position and their cash
flows for each of the two years in the period ended December 31, 1996 and for
the nine months ended September 30, 1997, in conformity with generally
accepted accounting principles in Colombia, applied on a consistent basis
except for the change in depreciation method discussed in Note 7.
 
  Accounting principles generally accepted in Colombia, as described in Notes
2 and 3 to the financial statements, vary in certain significant respects from
accounting principles generally accepted in the United States of America. The
application of the latter would have affected the determination of
consolidated net income expressed in constant Colombian pesos of September 30,
1997 purchasing power for each of the two years in the period ended December
31, 1996 and for the nine months ended September 30, 1997, and the
determination of consolidated shareholders' equity also expressed in constant
Colombian pesos of September 30, 1997 purchasing power at December 31, 1995
and 1996 and September 30, 1997 to the extent summarized in Note 28 to the
consolidated financial statements.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
  (THOUSANDS OF PESOS OF SEPTEMBER 30, 1997 PURCHASING POWER--NOTE 2, UNLESS
                             OTHERWISE SPECIFIED)
 
NOTE 1--REPORTING ENTITY
 
  Transtel S.A. (hereafter, Transtel S.A. and its subsidiaries are referred to
as the "Company" or "Transtel") was created under Colombian law on August 23,
1993 for a term expiring on August 23, 2023; this term may be extended by an
amendment of the Company's bylaws.
 
  The Company's business consists of the design, installation, operation and
ownership of fixed telephony networks in various areas of Colombia.
 
  To date, Transtel has grown through the formation of subsidiaries with
municipalities as their minority shareholders. Transtel contributed cash
(except in the case of Caucatel where Transtel's contribution consisted of
cash and equipment) to each subsidiary in exchange for a majority ownership.
In exchange for a minority ownership position in the subsidiary, the relevant
municipality either (i) transferred its currently owned telecommunications
infrastructure along with its cooperation in various forms, including the
provision of its demographic information and the required civil works permits
on an expedited basis, or (ii) where such current infrastructure does not
exist, contributed nominal cash and demographic information and permits
cooperation only. Once the subsidiary structure is in place, Transtel then
focuses on expanding the subscriber base and either upgrading the current
infrastructure or building a new infrastructure, as the case may be.

  In addition to the above subsidiaries, Transtel formed TeleCauca S.A. E.S.P.
as a 98% owned subsidiary on December 27, 1996; however, it has had no
operations to date.
 
  As of September 30, 1997, Transtel S.A. had no significant operations or
assets except for its investments in its subsidiaries. Transtel S.A. was in
the preoperating stage until September 1, 1995.
 
  TeleJamundi and Unitel were formed by Transtel S.A. contributing cash of
Ps24,412 and Ps75,515 respectively. The municipalities of Jamundi and Yumbo
contributed Ps10,462 and Ps18,879 in cash for their minority interests in
TeleJamundi and Unitel, respectively, as these municipalities did not own
existing telephony systems.
 
  TelePalmira was formed by Transtel S.A. contributing cash of Ps13,428,217
for a 60% interest and the municipality of Palmira contributing a portion of
its telephony system with a fair value of Ps8,952,144 for a 40% minority
interest. Concurrently, TelePalmira purchased the remaining assets of
Palmira's telephony system for Ps12,085,411 in cash.

NOTE 2--BASIS OF FINANCIAL STATEMENT PRESENTATION
 
 Consolidation
 
  Companies in Colombia must keep their accounting records and prepare their
financial statements in conformity with rules prescribed by the Government of
Colombia. These are considered by law to be accounting principles generally
accepted in Colombia ("Colombian GAAP"). Consolidated financial statements in
Colombia include the subsidiaries in which the Company owns, directly or
indirectly, more than 50% of the common stock. All of the Company's
subsidiaries are consolidated, eliminating intercompany accounts and
transactions.
 
 Inflation accounting
 
  The consolidated financial statements, as required by law, have been
adjusted for the effects of inflation on the basis of changes in the official
Colombian middle-income consumer price index ("MCPI"). This index is applied,
on a one-month lagging basis, to nonmonetary assets and liabilities,
shareholders' equity (excluding the surplus from reappraisal of assets) and
revenue and expense accounts. Monetary balances have not been adjusted because
they reflect the purchasing power of the currency at the date of the balance
sheet. The Company's management considers that the application of the one-
month lagging basis in the inflation adjustments does not deviate materially
from the calculation performed on a current-month basis.
 
                                      F-9

                                 TRANSTEL S.A.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The adjusted costs of the non-monetary assets may not exceed the net
realizable value of the assets.
 
  The exposure to inflation is reflected in each non-monetary item of the
consolidated financial statements. The net gain or loss from exposure to
inflation is reflected as "Net monetary inflation adjustment income (loss)" in
the consolidated statements of income. The individual components of the
consolidated statements of income have been adjusted to reflect the effect of
inflation during the year. The net effect of inflation during the year on
these revenue and expense components is recorded as a portion of the "Net
monetary inflation adjustment income (loss)" account.
 
  Accordingly, the "Net monetary inflation adjustment income (loss)" shown in
the income statement of the Company is the result of netting or offsetting the
following items:
 
    A. A credit (or income entry) for inflation affecting non-monetary
  assets;
 
    B. A charge (or expense entry) for inflation affecting non-monetary
  liabilities and shareholders' equity; and
 
    C. Charges and credits (for expense and income entries) representing
  inflation adjustments made to expenses and revenues, respectively. Since
  monetary inflation adjustments are offset in the net monetary inflation
  adjustment account in the statement of income, the net effect on net income
  from the expense and income inflation adjustments is zero. The inflation
  adjustments to revenue and expenses are included in the individual revenue
  and expense captions in the income statement.
 
  Because expense and revenue inflation adjustments net to zero, the only
impact on the consolidated statement of income of the effects of inflation is
attributable to the restatement of non-monetary assets and liabilities and
shareholders' equity accounts.
 
  The financial statements for 1995 and 1996 have been restated to constant
pesos of purchasing power of September 30, 1997. The constant pesos amounts
have been determined by applying an index derived from the MCPI to the nominal
amounts reflected in the statutory financial statements prepared under
Colombian GAAP. The indexes applied to the nominal financial statements data
for 1995 and 1996 were 1.393 and 1.141, respectively. Some components of the
statements of cash flows, of changes in financial position and of changes in
shareholders' equity were restated using average indexes of 1.8476 and 1.25765
for 1995 and 1996, respectively.
 
NOTE 3--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The Company's significant accounting policies and procedures are described
below:
 
 Inventories
 
  Inventories of materials, cables, spare parts and other supplies are stated
at the lower of average cost adjusted for inflation or market.
 
 Properties, plant and equipment
 
  The amounts recorded for telecommunications equipment and networks that were
contributed to subsidiaries by municipalities and minority interest are valued
at estimated fair value of the equipment and networks and are in proportion to
the cash or fair value of assets contributed to the subsidiaries by Transtel
since the historical book value records of these municipalities are non-
existent or unreliable. If reliable historical book value amounts are
available for future acquisitions, the Company will record the acquisitions at
the municipalities' historical book value plus Transtel's portion of the
excess of fair value over that book value. Other purchases from municipalities
are recorded at amounts payable in cash. Subsequently, these assets are
adjusted for inflation.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Other properties, plant and equipment are recorded at historical cost
adjusted for the effects of inflation. Sales and retirements of these assets
are removed at their net inflation-adjusted cost, and differences between sale
proceeds and net inflation-adjusted cost were recorded as gains or losses,
according to each case.
 
  Disbursements for additions to and substantial improvements of assets are
capitalized and adjusted for inflation. Interest costs incurred during the
construction period are capitalized. Maintenance and repair expenditures are
expensed as incurred.
 
  Depreciation is calculated on the basis of the cost of assets, adjusted for
inflation, over their estimated useful lives as follows:

                                                                   -------------
   <S>                                                             <C>

   External telephony networks....................................       20
</TABLE>
 
  Prior to January 1, 1996, the Company used the straight-line method of
depreciation. As of January 1, 1996, TelePalmira changed to the reverse sum of
the years method of depreciation, a method acceptable in Colombia. All other
operating subsidiaries also use this method.
 
 Allowance for doubtful accounts
 
  The allowance for doubtful accounts is reviewed and updated at the end of
each year on the basis of evaluations of collectibility based on agings of
customer receivables and management's judgment. Uncollectible balances are
periodically charged against the allowance account.
 
 Deferred charges
 
  Items recorded as deferred charges include disbursements for software,
leasehold improvements, organization costs, preoperating expenses until
Transtel S.A. and each subsidiary commences commercial operations, costs of
market and demand studies and investigations, costs related to several
acquisitions and bond issuance costs. In addition, the Company has recorded as
deferred charges interest on the financing of its investments in its
subsidiaries until their commercial operations commence.
 
  These deferred costs are adjusted for inflation with a credit to "Deferred
monetary correction," a liability, and, concurrently, the inflation adjustment
of the part of shareholders' equity used to finance such costs is deferred by
a debit to an asset account "Deferred monetary correction". All deferred
costs, except bond issuance costs, and expenses arising from monetary
correction are amortized over five years from the time when the studies and
investigations are completed or when commercial operations begin. Bond
issuance costs will be amortized over the life of the bonds.
 
 Reappraisal of assets
 
  Reappraisals of properties, plant and equipment, which increase
shareholders' equity are calculated as the excess of appraised values of
properties, plant and equipment (as periodically established by independent
appraisers) over their net adjusted book values. The initial reappraisal was
recorded in 1996. Such reappraisal

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
amounts are not depreciated. A provision charged to results should be recorded
when appraisals are lower than the net adjusted book value of properties,
plant and equipment.
 
 Translation of foreign currency transactions and balances
 
  Foreign currency transactions and balances are translated into Colombian
pesos at the representative market exchange rate. This representative rate for
the United States dollar in Colombian nominal pesos was Ps987.65, Ps1,005.33
and Ps1,246.27 per $1 at December 31, 1995, December 31, 1996 and September
30, 1997, respectively. Foreign exchange differences are recognized as
financial income or expense. The only foreign currency balances were
borrowings from financial entities of $15,171,541 (Ps17,402,995) at December
31, 1996 and $30,091,000 (Ps37,501,510) at September 30, 1997, certificates of
deposits of Ps2,010,660 ($2,000,000) and Ps2,492,540 ($2,000,000) at December
31, 1996 and September 30, 1997, respectively, and prepayments and advances of
Ps537,540 ($431,300) at September 30, 1997.
 
 Labor liabilities
 
  Labor liabilities are adjusted at the end of each accounting period by
reference to legal provisions and labor agreements in force.
 
  The Social Security Institute of Colombia has the responsibility for the
pension liability for employees of the Company. The Company and its employees
are required to contribute monthly to a pension fund based on a percentage of
salaries.
 
  Under Colombian labor regulations, employees are entitled to receive one
month's salary for each year of service. The Company contributes these amounts
within 30 days of its year end to a fund established by each employee.
 
 Recognition of revenues, costs and expenses
 
  Revenues for telephone services are recognized in the period during which
the services are provided. Revenues from settlement of traffic for national
and international long distance calls are recognized on a net basis and are
based on estimates of traffic volume and rates. Certain revenues subject to
final settlement are not recorded until realization is probable. Revenues for
connection fees for telephone lines are recognized upon payment in cash or the
execution of a promissory note (with a 10% down payment) by the customer and
the Company's assignment of a telephone number which is transferable to others
by the customer. Actual connection with a dial tone takes place within a day
to approximately three months depending on the customer's location in relation
to the buildout of the system. Costs and expenses are recorded on the accrual
basis.
 
 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 at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Subsequent resolution of some matters
could differ from those estimates.
 
 Income tax
 
  The tax provision includes tax resulting from timing differences and other
expenses deductible for tax purposes which differ from recorded expenses for
financial statement purposes. The tax benefit or expense relating to such
timing differences is recorded in deferred income tax asset or liability
accounts.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Memorandum accounts
 
  Items recorded as memorandum accounts include guarantees, remaining payments
on lease agreements and assets given as collateral. Contingent
responsibilities mainly represent the amounts of promissory notes payable from
connection fees sold to financial institutions with recourse to the Company,
which are not collected yet. Memorandum accounts called fiscal accounts are
also recorded for differences between financial statement data and data for
income tax purposes. Nonmonetary memorandum accounts are adjusted for
inflation, with a charge or credit to reciprocal memorandum accounts.
 
 Statement of cash flows
 
  For purposes of reporting cash flows, cash and cash equivalents are defined
as cash and highly liquid debt instruments with an original maturity of three
months or less. The statements of cash flows are prepared substantially in
conformity with generally accepted accounting principles in the United States
("U.S. GAAP").
 
  During 1995 and the nine months ended September 30, 1997, the Company
recorded non-cash transactions for properties, plant and equipment and
minority interest of Ps8,952,144 and Ps14,107,578, respectively, related to
the acquisitions of the telephony assets of municipalities. Additionally the
Company recorded non-cash transactions for land and capital lease obligations
of Ps1,063,307 in 1996.
 
 Earnings per share
 
  Earnings per share are computed by dividing net income applicable to common
shares by the weighted average number of subscribed and paid shares
outstanding for each year presented. Transtel's weighted average number of
shares used in the computation of earnings per share was 2,294,444,444 and
4,000,000,000 in 1995 and 1996, respectively, and 4,231,066,938 for nine
months ended September 30,1997
 
 Convenience translation to U.S. dollars (unaudited)
 
  Transtel maintains its accounting records and prepares its financial
statements in Colombian pesos ("Pesos"). The U.S. dollar ("Dollar") amounts
presented in the financial statements and accompanying notes have been
translated from the Peso figures solely for the convenience of the reader, at
the exchange rate of 1,246.27 Pesos per Dollar, which approximates the
exchange rate which existed at September 30, 1997. Such translation should not
be construed as representations that the Peso amounts represent, or have been
or could be, converted into Dollars at that or any other rate.

  On August 31, 1996, the Company received 100% of the shares of Gonzalo
Caicedo Toro & Cia. S.C.S. ("GCT & Cia.") from Mr. Gonzalo Caicedo Toro, a
shareholder of the Company, for Ps2,657,890 in payment of the Company's net
advances to him (see Notes 5 and 25). GCT & Cia. owns 6% of the Company and an
interest in Colombina S.A., a candy manufacturer in Colombia. The Company
pledged the shares of GCT & Cia. as collateral for certain of its borrowings.
On July 21, 1997, the Company sold the shares in GCT & Cia. to Mr. Caicedo for
cash equal to the price paid by the Company. Since the Company's ownership of
GCT & Cia. was temporary, the investment has been recorded at cost as a
temporary investment at December 31, 1996.
 
  Certificates of deposits earned interest at rates between 18% and 20% in
1995, 25% and 30% in 1996, and 20% and 22% in 1997.
 
  The investment in the trust fund earned interest rate of 21% in 1997.

NOTE 11--DEBT
 
  On October 28, 1997, the Company received the net proceeds from the sale of
$150 million of its 12 1/2% Senior Notes due 2007. These Senior Notes were
sold to a trust which issued certificates representing pro rata interests in
the Senior Notes to qualified institutional buyers in the United States of
America or non-U.S. persons outside the United States. Interest on the Senior
Notes will be due on May 1 and November 1, commencing May 1, 1998.
 
  A portion of the net proceeds of the 12 1/2% Senior Notes due 2007 was used
to pay all existing short and long-term debt existing at October 28, 1998. The
following debt tables reflect the reclassifications of short-term debt and the
current portion of long-term debt as long-term at September 30, 1997 (see Note
27).
 
  The indenture of the Senior Notes imposes certain limitations on the ability
of the Company and its subsidiaries to, among other things, incur additional
indebtedness, incur liens, pay dividends or make certain other restricted
payments, consummate certain asset sales, enter into certain transactions with
affiliates, issue preferred stock, merge or consolidate with any other person
or sell, assign, transfer, lease, convey, or otherwise dispose of all or
substantially all of the assets of the Company and its subsidiaries.

NOTE 15--INCOME TAX
 
  Consolidated income tax returns are not permitted in Colombia. The effective
statutory income tax rate for Transtel S.A. was 35% for 1995, 1996 and 1997.
Transtel's taxable income is presumed to be not less than the greater of 5%
(4% in 1995) of shareholders' equity for tax purposes at the end of the
immediately preceding year or 1.5% of gross assets for tax purposes at the end
of the immediately preceding year; however, operating companies (Transtel's
subsidiaries) are not subject to presumpted income tax.
 
  In accordance with Law 142 of 1994 and Law 223 of 1995, entities which
render basic residential telephony services and which are mixed capital
companies (i.e., companies with both public and private capital such as the

Company's subsidiaries) are exempt in 1995 and partially exempt from the
payment of income taxes for a term of seven years from 1996 with respect to
profits which are retained for upgrade, expansion or replacement of telephone
systems. These companies are exempt from taxes on 100% of income related to
basic telephony services for 1995 and 1996; thereafter the exemption reduces
by 10 percentage points each taxable year through 2000 and then reduces by 20
percentage points in 2001 and 2002. After 2002, there is no exemption.
 
  In July 1997, Law 383 of 1997 established that dividends declared from
companies similar to Transtel's subsidiaries and paid to government entities
are not taxable. As there is not a similar exclusion for private investors
such as Transtel S.A, the Company expects that future dividends declared to
Transtel S.A. will be taxable to it. At September 30, 1997, deferred income
taxes calculated on Transtel S.A.'s distributable portion of net income earned
by its subsidiaries through that date amounted to Ps960,985, which is included
in deferred income taxes and other long-term liabilities.
 
  The following is a reconciliation of taxable income before taxes and
minority interest for the years ended December 31, 1995 and 1996 and the nine

  The Company's income tax returns for the years 1995 and 1996 are subject to
review and acceptance by the tax authorities. The tax returns for the year
ending December 31, 1997 of each company will be filed between April and June
1998. The Company's management and its legal advisors believe that no material
tax liabilities in excess of those recorded will arise as a result of any such
eventual reviews. The Company and its subsidiaries do not have any pending
claims from the tax authorities.

NOTE 18--SHAREHOLDERS' EQUITY
 
  Effective July 7, 1997, the capital of Transtel S.A. consisted of 50 billion
authorized shares of common stock with a par value of one nominal peso each.
At December 31, 1996 and September 30, 1997, 4 billion shares and 5 billion
shares, respectively, were issued and outstanding.
 
  In July 1997, two of the existing shareholders subscribed to a total of
1,039,801,222 shares of the Company's common stock for a total of Ps31,153,570
(30 single Pesos per share). These shareholders paid Ps30,871,724 in July 1997
and the remaining unpaid balance of Ps281,846 at September 30, 1997 was paid
in October 1997. The Company reduced a portion of its borrowings with the cash
received.
 
 Legal reserve
 
  Pursuant to Colombian law, 10% of the net profit of the parent company and
its Colombian subsidiaries in each year must be appropriated with a credit to
a "reserve fund" until it is equivalent to at least 50% of the subscribed
capital. This legal reserve may not be reduced to less than the indicated
percentage, except to cover losses in excess of undistributed profits.
 
 Reserve for future construction
 
  Reserves other than the legal reserve, appropriated directly out of retained
earnings, are freely distributable by the shareholders in general meeting.

NOTE 26--COMMITMENTS
 
 GLOBAL-SIEMENS ARRANGEMENTS
 
  Global Telecommunications Operations, Inc. ("Global") is a British Virgin
Islands company owned by the same shareholders who own Transtel. Global was
formed in January 1995 as a financing vehicle for the purchase of certain
equipment from Siemens AG ("Siemens"). As part of the Company's expansion
plan, Global has entered into two purchase agreements and two letters of
intent with Siemens for the provision of certain equipment necessary for the
Company's expansion plan. Global has entered or intends to enter into a lease
agreement with each subsidiary for the lease of such telecommunications
equipment to each subsidiary on terms substantially similar to the financing
to Global from Siemens. Transtel purchased equipment to be used by Caucatel
directly from Siemens ($3.3 million switches and $500,000 for installation)
and contributed it to Caucatel as part of its capital. Caucatel is the only
subsidiary that does not lease its equipment from Global. Under these leases,
if the subsidiaries default under the leases, Global has the right to take
action against the assets leased thereunder including repossession or sale of
the equipment. Global has assigned to Siemens the lease payments under each of
the leases in the event of an event of default under the purchase agreements
occurs and is continuing. The following transactions with Global are accounted
for as operating leases under Colombian GAAP and as capital leases under U.S.
GAAP (see Note 28 (d)(vi)):
 
  Global I Purchase Agreement. On May 2, 1996, Global entered into a purchase
agreement with Siemens (as amended on July 28, 1997, the "Global I Purchase
Agreement") to purchase certain landline telecommunications equipment to be
used for the development of each of TelePalmira's, TeleJamundi's and Unitel's
respective wireline networks for an aggregate amount of approximately $20.0
million, of which 15% (approximately $3.0 million) was paid upon execution of
the Global I Purchase Agreement. The remaining 85% of the price of equipment
delivered and installed by Siemens under the Global I Purchase Agreement is
payable by Global in 20 semi-annual payments. Global's obligations under the

with Unitel (the "Global-Unitel II Lease") and TeleCartago (the "Global-
TeleCartago Lease") for certain of the equipment that is the subject of the
Global II Purchase Agreement. Global intends to lease the remainder of the
equipment that is the subject of the Global II Purchase Agreement to Bugatel
under leases with terms and conditions similar to those of the Global I Leases
(the Global-Unitel II Lease and the Global-TeleCartago Lease, together with
the lease to be entered into with Bugatel are collectively referred to herein
as, the "Global II Leases").
 
    Global-Unitel II Lease. Pursuant to the Global-Unitel II Lease, Unitel
  agreed to pay Global an aggregate amount of $26.9 million to lease, for a
  12-year term, certain wireless telecommunications equipment that Global

CONSTRUCTION ARRANGEMENTS
 
  On April 30, 1996, each of TelePalmira, Unitel (with respect to its wireline
applications) and TeleJamundi entered into turn-key arrangements (the "Turn-
Key Arrangements") with Siemens S.A., a Colombian Corporation, to (i) install
the lines, switches and other equipment leased by each of these subsidiaries
from Global under the Global I Leases, (ii) put in operation such lines and
equipment, (iii) manage the "cut-over" to the new system lines, install air
conditioner equipment and train the personnel who will operate the switching
equipment, (iv) install a transmission signaling standard (v) expand, replace
and install the outside plant, and (vi) complete expansion of the network. The
aggregate amount due to Siemens S.A. under these Turn-Key Arrangements is
approximately $8.1 million.
 
  For each of the Turn-Key Arrangements described in the paragraph above,
Siemens S.A. has provided the respective subsidiary with performance bonds
equivalent to (i) 10% of the amount of each Turn-Key Arrangement, (ii) 5% of
the services contracted under each Turn-Key Arrangement, (iii) 10% of the cost
of the outside plant civil works and (iv) up to $100,000 for personal or
property liability.
 
  On June 18, 1997, each of Transtel (in place of Bugatel, which was not yet
formed), TeleCartago and Unitel (with respect to its wireless applications)
entered into Turn-Key Arrangements with Siemens to (i) install the lines,
switches and other equipment leased by Bugatel, TeleCartago and Unitel from
Global under the Global II Leases, and (ii) put in operation such lines and
equipment. The aggregate amount due to Siemens under these Turn-Key
Arrangements is approximately $6.9 million. Siemens S.A. has provided
Transtel, TeleCartago, and Unitel with performance bonds substantially similar
to those provided to TelePalmira, Unitel and TeleJamundi. In connection with
the negotiations to amend the Global II Purchase Agreement, the Company
expects to reduce the amount due to Siemens under this Turn-Key Arrangement to
approximately $5.3 million.
 
  On May 23, 1997, Transtel entered into a Turn-Key Arrangement with Siemens
to (i) install the lines, switches and other equipment that Transtel agreed to
contribute to the capital of Caucatel as part of its capital contribution and
which the Company acquired from Siemens pursuant to the Transtel-Siemens
arrangements, and (ii) put in operation such lines and equipment. The
aggregate amount due to Siemens S.A. under this Turn-Key Arrangement is
approximately $460,000.

  On December 31, 1997, Empresa de Telecomunicaciones de Girardot S.A. E.S.P
("TeleGirardot"), a new subsidiary of Transtel, was formed by Transtel
contributing Ps8,898,299 in cash for its 60% interest and the municipality of
Girardot contributing the net assets of its wholly-owned telephone subsidiary,
Empresa de Telecomunicaciones de Girardot E.S.P. ("Girardot Telephone")
totaling Ps5,932,199 for its 40% minority interest. Transtel used a portion of
the proceeds from the Senior Notes to finance its investment in TeleGirardot.
The transaction will be accounted for at the municipality's historical book
value plus Transtel's portion of the excess of fair value over that book value
since prior accounting records for Girardot Telephone are available.

 (d) SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN COLOMBIAN AND U.S. GAAP:
 
  (i) Deferred income taxes
 
  Under Colombian GAAP, deferred income taxes are generally recognized for
timing differences in a manner similar to Accounting Principles Board Opinion
No. 11.
 
  Under U.S. GAAP, Statement of Financial Accounting Standards ("SFAS") No.
109, "Accounting for Income Taxes" requires that deferred tax assets or
liabilities be recorded for the tax effects of temporary differences between
the financial and tax bases for assets and liabilities. A valuation allowance
is provided for deferred tax assets when it is considered more likely than not
that they will not be realized.

  Under U.S. GAAP, there are no operating lease commitments at September 30,
1997. See Note 26 for the Global Leases that will be recorded as capital
leases upon commencement of the lease periods.
 
  (vii) Revenue recognition
 
  Under Colombian GAAP, revenues for connection fees for telephone lines are
recognized upon payment in cash or the execution of a promissory note (with a
10% down payment) by the customer and the Company's assignment of a telephone
number which is transferable to others by the customer. Under U.S. GAAP,
revenues from these connection fees are recorded at the date of actual
installation with a dial tone.
 
  (viii) Adjustment for inflation
 
  The difference in accounting for capital leases between Colombian and U.S.
GAAP creates an additional U.S. GAAP difference in the related inflation
adjustment. Additionally, the deferred monetary correction asset and liability
are reversed for U.S. GAAP.
 
  The components of the inflation adjustment to income are as follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  (ix) Minority interest
 
  The minority interests' share of the differences between Colombian GAAP and
U.S. GAAP are presented separately.
 
  (x) Distribution to shareholder
 
  Transtel purchased land and building from a major shareholder at appraised
value in August 1996. For U.S. GAAP, the difference between the amount paid
(Ps1,711,501) and the shareholder's historical basis Ps1,385,918 is treated as
a distribution to the shareholder in 1996.
 
  (xi) Acquisitions
 
  For U.S. GAAP purposes, the Company's accounting policy for acquisitions in
the form of subsidiaries formed with municipalities as minority interests is
to use estimated fair value to record the initial contribution of telephone
systems and the minority interest when the municipalities' historical book
value records are nonexistent or unreliable. If reliable historical book value
amounts are available, the Company will record telephone systems acquired and
minority interests at the municipalities' historical book values plus
Transtel's portion of the excess of fair value over that book value. There are
no differences between U.S. and Colombian GAAP for the years ended December
31, 1995 and 1996 and the nine months ended September 30, 1997.
 
  (xii) Earnings per share
 
  Under Colombian GAAP, earnings per share are computed by dividing net income
(loss) applicable to common shares by the weighted average number of common
shares outstanding for each period presented.
 
  Under U.S. GAAP, earnings per share are calculated on the basis of the
weighted average number of common shares outstanding, adjusted for stock
dividends issued by the Company which are considered outstanding since the
beginning of the earliest period presented. For U.S. GAAP, the weighted
average number were 2,294,444,444 and 4,000,000,000 during 1995 and 1996,
respectively, and 4,231,066,938 for the nine months ended September 30, 1997,
the same as under Colombian GAAP since no stock dividends have yet been
declared.
 
  Basic and fully diluted loss per share under U.S. GAAP were (1.25) Pesos and
(0.73) Pesos in 1995 and 1996, respectively, and (0.37) Pesos in the nine
months ended September 30, 1997.
 
 (E) 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 sold to financial institutions. 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
 
  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 SFAS 121 did not have any
material impact on Transtel's financial position or results of operations.

                                 TRANSTEL S.A.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Fair value of financial instruments
 
  Cash, short-term and temporary investments, accounts receivable and accounts
payable: The carrying amounts approximate fair value because of the short
maturity of these instruments or, in the case of temporary investments, the
subsequent sales price.
 
  Long and short-term debt: Substantially all of the Company's long- and
short-term debt is variable rate borrowings; thus, the carrying amounts of the
Company's borrowings under its credit agreements approximate their fair value.
 
  Capital lease obligations: The Company's capital lease obligations contain
variable interest rates and approximate fair value.

ITEM 22. UNDERTAKINGS.
 
  (1) The undersigned Registrant hereby undertakes that insofar as
indemnification for liabilities arising under the Securities Act 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 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.
 
  (2) The undersigned Registrant hereby undertakes: (i) to respond to requests
for information that is incorporated by reference into the Prospectus pursuant
to Items 4, l0(b), 11 or 13 of Form F-4) within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means; and (ii) to arrange or provide for a facility in
the U.S. for the purposes of responding to such requests. The undertaking in
(i) above includes information contained in documents filed subsequent to the
effective date of the registration statement through the date of responding to
the request.

OFFICIALLY RECORDED PROCEEDING NUMBER: (485)

FOUR HUNDRED EIGHTY-FIVE

In the city of Cali, capital of the administrative district of Valle del Cauca,
Republic of Colombia, on the THIRTEENTH (13TH) day of the month of FEBRUARY of
1997, before me MARIA SOL SINISTERRA ALVAREZ, Notary FOURTEEN of the Cali
association, there appeared Mr. GUILLERMO O. LOPEZ ESQUIVEL, of legal age and
resident of Cali, identified with citizenship document number 16,614,481 issued
in Cali and military record number E178078 of military zone number 16, marital
status married, with marital partnership in effect, legally competent to enter
into contract and bind himself, and stated:

FIRST: That in this instrument he is acting in his capacity of President and
legal representative of the company TRANSTEL S.A., constituted by means of
officially recorded proceeding number 3,097, executed on August 23, 1993, at
notarial office Fourteen of the Cali Association, circumstances which he proves
with the certificate of existence and representation, issued by the Chamber of
Commerce of Cali, a document which he attaches to this text in order that it may
form a part thereof and of the copies of same which may be issued.

SECOND: That at the extraordinary session of the meeting of shareholders of
TRANSTEL S.A. which took place on the eighth day of July of one thousand nine
hundred ninety-six, that statutory body approved, with the required quorum, the
general revision of the current bylaws of the company.

THIRD: That duly empowered by the Extraordinary Meeting of Shareholders of the

          Section 2.01. Form and Dating.

          The Notes and the Indenture Trustee's certificate of authentication
relating thereto shall be substantially in the form of Exhibit A hereto.  The
Notes may have notations, legends or endorsements required by law, stock
exchange rule or depository rule or usage.  The Company shall approve the form

satisfactory to the Indenture Trustee.  Each Note shall be dated the date of its
authentication.

                                      -27-
<PAGE>
 
          The terms and provisions contained in the Notes, annexed hereto as
Exhibit A, shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, the Company and the Indenture Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby.

          Notes offered and sold in reliance on Rule 144A shall be issued
initially in the form of one or more permanent global Notes in registered form,
substantially in the form set forth in Exhibit A (a "144A Global Note"),
deposited with Marine Midland Bank, as custodian for the Depository, duly
executed by the Company and authenticated by the Indenture Trustee as
hereinafter provided and shall bear the legend set forth in Section 2.15.  The
aggregate principal amount of a Rule 144A Global Note may from time to time be
increased or decreased by adjustments made on the records of the Indenture
Trustee, as custodian for the Depository, as hereinafter provided.  Notes
offered and sold in offshore transactions in reliance on Regulation S shall be
issued in the form of one or more permanent global Notes in registered form in
substantially the form set forth in Exhibit A (a "Regulation S Global Note"),
deposited with Marine Midland Bank, as custodian for the Depository for the
operator of Euroclear and Cedel for credit to the respective accounts of the
beneficial owners of the Regulation S Global Note, duly executed by the Company
and authenticated by the Indenture Trustee as hereinafter provided.  The
aggregate principal amount of a Regulation S Global Note may from time to time
be increased or decreased by adjustments made on the record of the Indenture
Trustee, as custodian for the Depositary, as hereinafter provided.  The 144A
Global Notes and Regulation S Global Notes are sometimes collectively herein
referred to as the "Global Notes."

          Notes offered and sold in reliance on any other exemption from
registration under the Securities Act other than as described in the preceding
paragraph shall be issued in the form of permanent certificated Notes in
registered form, in substantially the form set forth in Exhibit A (the "Physical
Notes") and shall bear the legend set forth in Section 2.15.


          Section 2.02. Execution and Authentication; Aggregate Principal
Amount.

          One Officer shall sign (who shall have been duly authorized by all
requisite corporate actions) the Notes for the Company by manual or facsimile
signature.

                                      -28-
<PAGE>
 
          If an Officer whose signature is on a Note was an Officer at the time
of such execution but no longer holds that office at the time the Indenture
Trustee authenticates the Note, the Note shall nevertheless be valid.

          A Note shall not be valid until an authorized signatory of the
Indenture Trustee manually signs the certificate of authentication on the Note.
The signature shall be conclusive evidence that the Note has been authenticated
under this Indenture.


          An Opinion of Counsel need not be provided for the authentication of
any Notes issued hereunder.

          The Indenture Trustee shall authenticate Notes for original issue in
the aggregate principal amount not to exceed $150,000,000 (the "Initial Notes")
and from time to time additional Notes in an amount not to exceed $30,000,000
(the "Additional Notes"), upon a written order of the Company in the form of an
Officers' Certificate.  The Officers' Certificate shall specify the amount of
Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be issued as Physical Notes or a Global
Note and whether or not the Notes shall bear the Private Placement Legend, or
such other information as the Indenture Trustee may reasonably request.  The
aggregate principal amount of Notes outstanding at any time may not exceed
$180,000,000, except as provided in this paragraph and in Section 2.07.

          The Indenture Trustee may appoint an authenticating agent (the
"Authenticating Agent") reasonably acceptable to the Company to authenticate
Notes.  Unless otherwise provided in the appointment, an Authenticating Agent
may authenticate Notes whenever the Indenture Trustee may do so.  Each reference
in this Indenture to authentication by the Indenture Trustee includes
authentication by such Authenticating Agent.  An Authenticating Agent has the
same rights as an Agent to deal with the Company or with any Affiliate of the
Company.  The Indenture Trustee initially appoints, and the Company approves the
appointment of, Marine Midland Bank, as Authenticating Agent.

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


          Section 2.03. Registrar and Paying Agent.

          The Company shall maintain an office or agency (which shall be located
in the Borough of Manhattan in the City of New York, State of New York) where
(a)

                                      -29-
<PAGE>
 
Notes may be presented or surrendered for registration of transfer or for
exchange, (b) Notes may be presented or surrendered for payment and (c) notices
and demands to or upon the Company in respect of the Notes and this Indenture
may be served. The Registrar shall keep a register of the Notes and of their
transfer and exchange. The Company, upon prior written notice to the Indenture
Trustee, may have one or more additional paying agents reasonably acceptable to
the Indenture Trustee. The term "Paying Agent" includes any additional Paying
Agent. The Company may act as its own Paying Agent, except that for the purposes
of payments on the Notes pursuant to Sections 3.07(b), 4.12 and 4.18 neither the
Company nor any Affiliate of the Company may act as Paying Agent.

          The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which agreement shall incorporate the
provisions of the TIA and implement the provisions of this Indenture that relate
to such Agent. The Company shall notify the Indenture Trustee, in advance, of
the name and address of any such Agent. If the Company fails to maintain a
Registrar or Paying Agent, or fails to give the foregoing notice, the Indenture
Trustee shall act as such.

          The Company initially appoints Marine Midland Bank as Registrar and,
Paying Agent until such time as Marine Midland Bank has resigned or a successor
has been appointed. Any of the Registrar, the Paying Agent or any other agent
may resign upon 30 days' written notice to the Company.

          The Indenture Trustee is authorized to enter into a letter of
representation with the Depository in the form provided to the Indenture Trustee
by the Company and to act in accordance with such letter.


          Section 2.04. Paying Agent To Hold Assets in Trust.

          The Company shall require each Paying Agent other than the Indenture
Trustee to agree in writing that each Paying Agent shall hold in trust for the
benefit of the Holders or the Indenture Trustee all assets held by the Paying
Agent for the payment of principal of, or interest on, the Notes (whether such
assets have been distributed to it by the Company or any other obligor on the
Notes), and the Company and the Paying Agent shall notify the Indenture Trustee
of any Default by the Company (or any other obligor on the Notes) in making any
such payment. The Company at any time may require a Paying Agent to distribute
all assets held by it to the

                                      -30-
<PAGE>
 
Indenture Trustee and account for any assets disbursed and the Indenture Trustee
may at any time during the continuance of any payment default under Article 6,
upon written request to a Paying Agent, require such Paying Agent to distribute
all assets held by it to the Indenture Trustee and to account for any assets
distributed. Upon distribution to the Indenture Trustee of all assets that shall
have been delivered by the Company to the Paying Agent, the Paying Agent shall
have no further liability for such assets.


          Section 2.05. Holder Lists.

          The Indenture Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of the Holders. The Company shall furnish or cause the Registrar to
furnish to the Indenture Trustee promptly after each Record Date and as of such
Record Date and at such other times as the Indenture Trustee may reasonably
request in writing a list as of such date and in such form as the Indenture
Trustee may reasonably require of the names and addresses of the Holders, which
list may be conclusively relied upon by the Indenture Trustee.


          Section 2.06. Transfer and Exchange.

          Subject to Section 2.17 hereof, when Notes are presented to the
Registrar with a request to register the transfer of such Notes or to exchange
such Notes for an equal principal amount of Notes of other authorized
denominations, the Registrar shall register the transfer or make the exchange as
requested if its requirements for such transaction are met; provided, however,
that the Notes presented or surrendered for registration of transfer or exchange
shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing. To permit registrations of
transfer and exchanges, the Company shall execute and the Indenture Trustee
shall authenticate Notes at the Registrar's request. No service charge shall be
made for any registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than any such transfer taxes or
similar governmental charge payable upon exchanges or transfers pursuant to
Sections 2.10, 3.06, 3.07(b), 4.12, 4.18 or 9.05, in which event the Company
shall be responsible for the payment of such taxes).

          The Registrar shall not be required to register the transfer of or
exchange of any Note (i) during a period beginning at the opening of business 15
days before the mailing of a notice of redemption of Notes and ending at the
close of business on the day of such mailing and (ii) selected for redemption in
whole or in part pursuant to Article Three, except the unredeemed portion of any
Note being redeemed in part.

                                      -31-
<PAGE>
 
          Any Holder of the Global Note shall, by acceptance of such Global
Note, agree that transfers of beneficial interests in such Global Notes may be
effected only through a book entry system maintained by the Holder of such
Global Note (or its agent), and that ownership of a beneficial interest in the
Note shall be required to be reflected in a book entry system.


          Section 2.07. Replacement Notes.

          If a mutilated Note is surrendered to the Indenture Trustee or an
Agent or if the Holder of a Note claims that the Note has been lost, destroyed
or wrongfully taken, the Company shall issue and the Indenture Trustee shall
authenticate a replacement Note if the Indenture Trustee's requirements are met.
Such Holder must provide an indemnity bond or other indemnity of reasonable
tenor, sufficient in the reasonable judgment of the Company, such Agent and the
Indenture Trustee, to protect the Company, the Indenture Trustee or any Agent
from any loss which any of them may suffer if a Note is replaced. Every
replacement Note shall constitute an additional obligation of the Company.


          Section 2.08. Outstanding Notes.

          Notes outstanding at any time are all the Notes that have been
authenticated by the Indenture Trustee except those cancelled by it, those
delivered to it for cancellation and those described in this Section as not
outstanding. Subject to the provisions of Section 2.09, a Note does not cease to
be outstanding because the Company or any of its Affiliates holds the Note.

          If a Note is replaced pursuant to Section 2.07 (other than a mutilated
Note surrendered for replacement), it ceases to be outstanding unless the
Indenture Trustee receives proof satisfactory to it that the replaced Note is
held by a bona fide purchaser. A mutilated Note ceases to be outstanding upon
surrender of such Note and replacement thereof pursuant to Section 2.07.

          If on a Redemption Date or the Stated Maturity of the Notes the Paying
Agent holds U.S. Legal Tender or U.S. Government Securities sufficient to pay
all of the principal and interest due on the Notes payable on that date and is
not prohibited from paying such money to the Holders thereof pursuant to the
terms of this Indenture, then on and after that date such Notes cease to be
outstanding and interest on them ceases to accrue.

                                      -32-
<PAGE>
 
          Section 2.09. Treasury Notes.

          In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver, consent or notice, Notes owned by
the Company or an Affiliate shall be considered as though they are not
outstanding, except that for the purposes of determining whether the Indenture
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes as to which a Responsible Officer of the Indenture Trustee has
received written notice of such ownership shall be so considered. The Company
shall notify the Indenture Trustee, in writing, when it or any of its Affiliates
repurchases or otherwise acquires Notes, of the aggregate principal amount of
such Notes so repurchased or otherwise acquired.


          Section 2.10. Temporary Notes.

          Until definitive Notes are ready for delivery, the Company may prepare
and the Indenture Trustee shall authenticate temporary Notes upon receipt of a
written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Notes to be
authenticated, the date on which the temporary Notes are to be authenticated,
whether such Notes shall bear the Private Placement Legend. Temporary Notes
shall be substantially in the form of definitive Notes but may have variations
that the Company considers appropriate for temporary Notes and so indicates in
the Officers' Certificate. Without unreasonable delay, the Company shall prepare
and the Indenture Trustee shall authenticate upon receipt of a written order of
the Company pursuant to Section 2.02 definitive Notes in exchange for temporary
Notes.


          Section 2.11. Cancellation.

          The Company at any time may deliver Notes to the Indenture Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Indenture
Trustee any Notes surrendered to them for transfer, exchange or payment. The
Indenture Trustee, or at the direction of the Indenture Trustee, the Registrar
or the Paying Agent, and no one else, shall cancel and, at the written direction
of the Company, shall dispose of all Notes surrendered for transfer, exchange,
payment or cancellation. Subject to Section 2.07, the Company may not issue new
Notes to replace Notes that it has paid or delivered to the Indenture Trustee
for cancellation. If the Company shall acquire any of the Notes, such
acquisition shall not operate as a redemption or satisfaction of the
Indebtedness represented by such Notes unless and

                                      -33-
<PAGE>
 
until the same are surrendered to the Indenture Trustee for cancellation
pursuant to this Section 2.11.


          Section 2.12. Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, it
shall pay the defaulted interest, plus (to the extent lawful) any interest
payable on the defaulted interest to the Persons who are Holders on a subsequent
special record date, which special record date shall be the fifteenth day next
preceding the date fixed by the Company for the payment of defaulted interest or
the next succeeding Business Day if such date is not a Business Day. The Company
shall notify the Indenture Trustee and Paying Agent in writing of the amount of
defaulted interest proposed to be paid on each Note and the date of the proposed
payment (a "Default Interest Payment Date"), and at the same time the Company
shall deposit with the Indenture Trustee or Paying Agent 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 Indenture Trustee or
Paying Agent 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 Section provided; provided that in no
event shall the Company deposit monies proposed to be paid in respect of
defaulted interest later than 10:00 a.m. New York time on the proposed Default
Interest Payment Date. At least 15 days before the subsequent special record
date, the Company shall mail (or cause to be mailed) to each Holder, as of a
recent date selected by the Company, with a copy to the Indenture Trustee and
Paying Agent, a notice that states the subsequent special record date, the
payment date and the amount of defaulted interest, and interest payable on such
defaulted interest, if any, to be paid. Notwithstanding the foregoing, any
interest which is paid prior to the expiration of the 30-day period set forth in
Section 6.01(b) shall be paid to Holders as of the regular record date for the
Interest Payment Date for which interest has not been paid. Notwithstanding the
foregoing, 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 Notes may be listed, and upon such notice as may be required by
such exchange.


          Section 2.13. CUSIP Number.

          The Company in issuing the Notes may use a "CUSIP" number, and, if so,
the Indenture Trustee shall use the CUSIP number in notices of redemption or
exchange as a convenience to Holders; provided, however, that no representation
is hereby deemed to be made by the Indenture Trustee as to the correctness or
accuracy

                                      -34-
<PAGE>
 
of the CUSIP number printed in the notice or on the Notes, and that reliance may
be placed only on the other identification numbers printed on the Notes. The
Company shall promptly notify the Indenture Trustee of any change in the CUSIP
number.



          Section 2.14. Deposit of Monies.

          Prior to 10:00 a.m. New York City time on each Interest Payment Date,
Stated Maturity of the Notes, Redemption Date, Change of Control Payment Date
and Net Proceeds Offer Payment Date, the Company shall have deposited with the
Paying Agent in immediately available funds money sufficient to make cash
payments, if any, due on such Interest Payment Date, Stated Maturity of the
Notes, Redemption Date, Change of Control Payment Date and Net Proceeds Offer
Payment Date, as the case may be, in a timely manner which permits the Paying
Agent to remit payment to the Holders on such Interest Payment Date, Stated
Maturity of the Notes, Redemption Date, Change of Control Payment Date and Net
Proceeds Offer Payment Date, as the case may be.


          Section 2.15. Restrictive Legends.

          Each Global Note and Physical Note that constitutes a Restricted
Security shall bear the following legend (the "Private Placement Legend") on the
face thereof until October 28, 1999, unless otherwise agreed by the Company and
the Holder thereof and unless specified in an Officers' Certificate delivered to
the Indenture Trustee and Registrar:

          THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES
          SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND, ACCORDINGLY, MAY
          NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE
          ACCOUNT OR BENEFIT OF, UNITED STATES PERSONS EXCEPT AS SET FORTH
          BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A)
          IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER
          THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL "ACCREDITED
          INVESTOR" (AS DEFINED IN RULE 501(a)(1), (2), (3) OR (7) UNDER THE

          Section 2.16. Book-Entry Provisions for Global Security.

          (a)  Each Global Note initially shall (i) be registered in the name of
the Depository or the nominee of such Depository, (ii) be delivered to the
Indenture Trustee as custodian for such Depository and (iii) bear legends as set
forth in Section 2.15. Each Global Note shall constitute a single Note for all
purposes of this Indenture.

                                      -37-
<PAGE>
 
          Members of, or participants in, the Depository ("Agent Members") shall
have no rights under this Indenture with respect to any Global Note held on
their behalf by the Depository, or the Indenture Trustee as its custodian, or
under a Global Note, and the Depository may be treated by the Company, the
Indenture Trustee and any Agent of the Company or the Indenture Trustee as the
absolute owner of a Global Note for all purposes whatsoever. Agent Members shall
hold their interest in a Global Note in accordance with the Applicable
Procedures. Accordingly, any Agent Member's beneficial interest in a Global Note
will be shown only on, and the transfer of such interest shall be effected only
through, records maintained by the Depositary or its nominee. Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Indenture Trustee
or any Agent of the Company from giving effect to any written certification,
proxy or other authorization furnished by the Depository or impair, as between
the Depository and its Agent Members, the operation of customary practices
governing the exercise of the rights of a holder of any Note.

          (b)  Transfers of a Global Note shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in a Global Note may be transferred or
exchanged for Physical Notes in accordance with the Applicable Procedures of the
Depository and, in the case of a transfer of a beneficial interest in a Global
Note to an Institutional Accredited Investor that is not a QIB, upon delivery of
a certificate in the form of Exhibit F by the transferee to the Registrar,
provided, however, that no Physical Note shall be issued in any denomination
less than the minimum authorized denomination therefor. In addition, Physical
Notes shall be transferred to all beneficial owners in exchange for their
beneficial interests in a Global Note if (i) the Depository notifies the Company
that it is unwilling or unable to continue as Depository for a Global Note and a
successor depositary is not appointed by the Company within 90 days of such
notice or (ii) an Event of Default has occurred and is continuing and the
Registrar has received a written request from the Depository to issue Physical
Notes.

          (c)  In connection with any transfer or exchange of a portion of the
beneficial interest in a Global Note to beneficial owners pursuant to paragraph
(b), the Registrar shall (if one or more Physical Notes are to be issued)
reflect on its books and records the date and a decrease in the principal amount
of such Global Note in an amount equal to the principal amount of the beneficial
interest in such Global Note to be transferred, and the Company shall execute,
and the Indenture Trustee shall authenticate and deliver, one or more Physical
Notes of like tenor and amount.

          (d)  In connection with the transfer of an entire Global Note to
beneficial owners pursuant to paragraph (b), such Global Note shall be deemed to
be surrendered to the Indenture Trustee for cancellation, and the Company shall
execute,

                                      -38-
<PAGE>
 
and the Indenture Trustee shall authenticate and deliver, to each beneficial
owner identified by the Depository in exchange for its beneficial interest in
such Global Note, an equal aggregate principal amount of Physical Notes of
authorized denominations.

          (e)  Any Physical Note constituting a Restricted Security delivered in
exchange for an interest in a Global Note pursuant to paragraph (b) or (c)
shall, except as otherwise provided by paragraph (c) of Section 2.17, bear the
legend regarding transfer restrictions applicable to the Physical Notes set
forth in Section 2.15.

          (f)  The Holder of the Global Note 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 Notes.


          Section 2.17. Special Transfer Provisions.

          (a)  Notwithstanding any other provision of this Indenture, transfers
and exchanges of Notes and beneficial interests in a Global Note shall be made
only in accordance with this Section 2.17.

          (i)  Rule 144A Global Note to Regulation S Global Note.  If the
               -------------------------------------------------         
     beneficial owner of a Rule 144A Global Note wishes at any time to transfer
     all or any portion of such interest to a Person who wishes to take delivery
     thereof in the form of a beneficial interest in a Regulation S Global Note,
     such transfer may be effected only in accordance with the provisions of
     this clause (a)(i) and the Applicable Procedures. Upon receipt by the
     Registrar of (A) a written order given in accordance with the Applicable
     Procedures from the Depository or its authorized representative directing
     the Registrar to credit or cause to be credited to a specified Depository
     Agent Member's account a beneficial interest in the Regulation S Global
     Note in a principal amount equal to the beneficial interest in the Rule 144
     Global Note to be so transferred, and (B) the proposed transferor of the
     beneficial interest of the Rule 144A Global Note delivers a certificate in
     the form of Exhibit G to the Registrar, then the Registrar shall (1) reduce
     the aggregate principal amount of the Rule 144A Global Note, (2) increase
     the aggregate principal amount of the Regulation S Global Note by the
     principal amount of such Notes so transferred, (3) endorse the appropriate
     schedules of each such Global Note in the amount of such reduction and
     increase, respectively, and (4) credit or cause to be credited to the
     account of the Person specified in such instructions a beneficial interest
     in the Regulation S Global Note having a principal amount equal to the
     amount so transferred.

                                      -39-
<PAGE>
 
          (ii) Regulation S Global Note to Rule 144A Global Note.  If the 
               -------------------------------------------------     
     beneficial owner of a Regulation S Global Note wishes at any time to
     transfer all or any portion of such interest to a Person who wishes to take
     delivery thereof in the form of a beneficial interest in a Rule 144A Global
     Note, such transfer may be effected only in accordance with the provisions
     of this clause (a)(ii) and subject to the Applicable Procedures. Upon
     receipt by the Registrar of (A) a written order given in accordance with
     the Applicable Procedures from a Depository Agent Member directing the
     Registrar to credit or cause to be credited to a specified Depository Agent
     Member's account a beneficial interest in the Rule 144A Global Note in the
     principal amount equal to the beneficial interest in the Regulation S
     Global Note to be so transferred, and (B) the proposed transferor of the
     beneficial interest of the Regulation S Global Note delivers a certificate
     in the form of Exhibit H to the Registrar, then the Registrar shall (1)
     reduce the aggregate principal amount of the Regulation S Global Note, (2)
     increase the aggregate principal amount of the Rule 144A Global Note by the
     principal amount of such Notes so transferred, (3) endorse the appropriate
     schedules of each such Global Note in the amount of such reduction and
     increase, respectively, and (4) credit or cause to be credited to the
     account of the Person specified in such instructions a beneficial interest
     in the Rule 144A Global Note having a principal amount equal to the amount
     so transferred.

        (iii)  Physical Note to a Global Note.  If the Holder of a Physical
               ------------------------------                              
     Note wishes at any time to transfer all or any portion of such Note to a
     Person who wishes to take delivery thereof in the form of a beneficial
     interest in a Global Note, such transfer may be effected only in accordance
     with the provisions of this clause (a)(iii) and subject to the Applicable
     Procedures. Upon receipt by the Registrar of (A) such Note as provided in
     Section 2.06 and instructions satisfactory to the Registrar directing that
     a specified principal amount not greater than the principal amount of such
     Note be credited to a specified Depository Agent Member's account or
     Euroclear or Cedel participant's account, as the case may be, and (B) the
     proposed transferor of the Physical Note delivers a certificate in the form
     of, in the case of sales under Rule 144A, Exhibit H, and in the case of
     sales under Regulation S, Exhibit G, to the Registrar, then the Registrar
     shall cancel such Physical Note (and issue a new Physical Note in respect
     of any untransferred portion thereof) and increase the aggregate principal
     amount of the Global Note by the principal amount of such Physical Note so
     transferred.

          (iv) Physical Note to Physical Note.  A Physical Note may be
               ------------------------------                         
     transferred, in whole or in part, to a Person who takes delivery in the
     form of

                                      -40-
<PAGE>
 
     another Physical Note, provided that if the Physical Note to be transferred
                            --------                                            
     evidences Restricted Securities, then the Registrar shall have received a
     certificate from the transferee in the form of Exhibit F from the
     transferor.

          (v)  Global Note to Physical Note.  A beneficial interest in a Global
               ----------------------------                                    
     Note may be exchanged for a Security that is not a Global Note only as
     provided in Section 2.16.

          (b)  Notwithstanding any other provision of this Indenture, Notes or
portions thereof may be transferred or exchanged only in principal amounts of
not less than the minimum authorized denomination therefor, and only if,
following such transfer or exchange, each Holder would hold Notes with a
principal amount of not less than such minimum authorized denomination.  Any
transfer, exchange or other disposition of Notes in contravention of this
Section 2.17(b) shall be deemed to be void and of no legal effect whatsoever,
any such transferee shall be deemed not to be the Holder or owner of any
beneficial interest in such Notes for any purpose, including but not limited to
the receipt of interest (including any Additional Interest) payable on such
Notes, and such transferee shall be deemed to have no interest whatsoever in
such Notes.

          (c)  Private Placement Legend.  Upon the transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Registrar
shall deliver Notes that do not bear the Private Placement Legend.  Upon the
transfer, exchange or replacement of Notes bearing the Private Placement Legend,
the Registrar shall deliver only Notes that bear the Private Placement Legend
unless (i) the requested transfer is after October 28, 1999, or (ii) there is
delivered to the Registrar and the Indenture Trustee an Opinion of Counsel
reasonably satisfactory to the Company and the Indenture 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.

          (d)  General.  By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture.

          The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 2.16 or this Section 2.17.
The Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time during the
Registrar's normal business hours upon the giving of reasonable written notice
to the Registrar.

          The notice shall identify the Notes to be redeemed and shall state:

          (a)  the redemption date;

          (b)  the redemption price;

          (c)  if any Note is being redeemed in part, the portion of the
     principal amount at maturity of such Note to be redeemed and that, after
     the redemption date upon surrender of such Note, a new Note or Notes in
     principal amount at maturity equal to the principal amount at maturity of
     the unredeemed portion shall be issued;

          (d)  the name and address of the Paying Agent;

          (e)  that Notes called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

     or printed on the Notes.

          At the Company's request, the Registrar shall give the notice of

however, that the Company shall have delivered to the Indenture Trustee and
Registrar, at least 45 days prior to the redemption date, an Officers'
Certificate requesting that the Indenture Trustee give such notice and setting
forth the information to be stated in such notice as provided in the preceding

the Indenture Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption price of, and accrued interest on, all
Notes to be redeemed.

          On and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption.  If a Note is redeemed
on or after an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record
date.  If any Note called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes
and in Section 4.01.

of any such sale of Capital Stock (other than Disqualified Stock), the Company
shall make such redemption not more than 120 days after the consummation of any
such sale or sales of Capital Stock.

case, to constitute an incurrence of such Indebtedness not permitted by this
clause (vi); (vii) Indebtedness of a Restricted Subsidiary issued to and held by
the Company; provided that (a) any subsequent issuance or transfer of any

the purpose of hedging against currency or interest rate risks with respect to
Indebtedness incurred in accordance with the first paragraph of clause (a) of
this Section and which the Company in good faith determines is non-speculative
in nature and is a bona fide hedge against fluctuations in currency values or
interest rates, respectively; provided, that in the case of Currency Agreements
that relate to other Indebtedness, such Currency Agreement does not increase the
Indebtedness of the obligor outstanding at any time other than as a result of
fluctuations in foreign currency exchange rates or by reasons of fees,
indemnities and compensation payable thereunder and in the case of Interest Rate
Agreements, the notional amount of such Interest Rate Agreement does not exceed

exceed $25.0 million.  The Company and its Subsidiaries may incur Acquired Debt
only in compliance with this covenant.

          (b)  For purposes of determining any particular amount of Indebtedness

of determining compliance with this Section, (A) in the event that an item of
Indebtedness meets the criteria of more than one of the types of Indebtedness
described in the above paragraph, the Company shall classify such item of
Indebtedness and only be required to include the amount of such Indebtedness in
one of such types of Indebtedness and (B) the amount of Indebtedness issued at a
price that is less than the principal amount thereof shall be equal to the
amount of the liability in respect thereof determined in conformity with GAAP.

          If the Company or any of its Restricted Subsidiaries shall create,
incur, assume or suffer to exist any Lien, other than a Permitted Lien, on any
assets or other property to secure Indebtedness in violation of this covenant,
the Company or such Restricted Subsidiary, as the case may be, shall make
effective provision for securing the Notes equally and ratably with such
Indebtedness as to such assets or other property for so long as such
Indebtedness shall be so secured.

          Notwithstanding the foregoing, Permitted Liens may not extend to the
Escrow Account, the Refinancing Account, the Escrow and Disbursement Agreement
or the Intercompany Notes.

transfer of any Capital Stock which results in any Wholly-Owned Subsidiary

to a Person not a Wholly-Owned Subsidiary will be deemed an issuance of
Preferred Stock; (iii) Preferred Stock issued by a Person prior to the time (a)
such Person became a Subsidiary, (b) such Person merges with or into a
Subsidiary or (c) another Person merges with or into such Person (in a

          The Company shall not, and shall not permit any Restricted Subsidiary
to, consummate any Asset Sale, unless (i) the consideration received by the
Company or such Restricted Subsidiary is at least equal to the Fair Market Value
of the assets sold or disposed of (as determined in good faith by the Company's

Trigger Date as permitted in clauses (A), (B) or (C) of the preceding sentence
(each a "Net Proceeds Offer Amount") shall be applied by the Company to make an
offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer
Payment Date") not less than 30 nor more than 45 days following the applicable
Net Proceeds Offer Trigger Date, from the Holders on a pro rata basis

                                      -56-
<PAGE>
 
that amount of Notes equal to the Net Proceeds Offer Amount at a price equal to
100% of the principal amount of the Notes to be purchased, plus accrued and
unpaid interest thereon, if any, to the date of purchase; provided, however,
that if at any time any non-cash consideration received by the Company or any
Restricted Subsidiary of the Company, as the case may be, in connection with any
Asset Sale is converted into or sold or otherwise disposed of for cash (other
than interest received with respect to any such non-cash consideration), then
such conversion or disposition shall be deemed to constitute an Asset Sale under
this Indenture and the Net Cash Proceeds thereof shall be applied in accordance
with this covenant.

          Notwithstanding the foregoing, if a Net Proceeds Offer Amount is less
than $5.0 million, the application of the Net Cash Proceeds constituting such
Net Proceeds Offer Amount to a Net Proceeds Offer may be deferred until such
time as such Net Proceeds Offer Amount plus the aggregate amount of all Net
Proceeds Offer Amounts arising subsequent to the Net Proceeds Offer Trigger Date
relating to such initial Net Proceeds Offer Amount from all Asset Sales by the
Company and its Restricted Subsidiaries aggregates at least $5.0 million, at
which time the Company shall apply all Net Cash Proceeds constituting all Net
Proceeds Offer Amounts that have been so deferred to make a Net Proceeds Offer
(the first date the aggregate of all such deferred Net Proceeds Offer Amounts is
equal to $5.0 million or more shall be deemed to be a Net Proceeds Offer Trigger
Date).

          Each Net Proceeds Offer shall be mailed within not less than 30 nor
more than 45 days following the applicable Net Proceeds Offer Trigger Date to
the record Holders as shown on the register of Holders, with a copy to the Pass
Through Trustee and the Indenture Trustee, and shall comply with the procedures
set forth in this Indenture.  Upon receiving notice of the Net Proceeds Offer,
Holders may elect to tender its Notes in whole or in part in integral multiples
of $1,000 in exchange for cash.  To the extent Holders properly tender Notes in
an amount exceeding the Net Proceeds Offer Amount, Notes of tendering Holders
shall be purchased on a pro rata basis (based on amounts tendered).  A Net
Proceeds Offer shall remain open for a period of 20 Business Days or such longer
period as may be required by law.

          The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder in
connection with the repurchase of Notes (and the repurchase by the Trust of the
Certificates) pursuant to a Net Proceeds Offer (whether or not such rule by its
terms would be applied to such offer as a matter of law).  To the extent that
the provisions of any securities laws or regulations conflict with the "Asset
Sale" provisions of this Indenture, the Company shall comply with the applicable
securities laws and regulations and shall

                                      -57-

not be deemed to have breached its obligations under the "Asset Sale" provisions
of this Indenture by virtue thereof


          Section 4.13. Limitation on Dividend and Other Payment Restrictions
     Affecting Restricted Subsidiaries.

          So long as any of the Notes are outstanding, the Company shall not,
and shall not permit any Restricted Subsidiary to, create or otherwise cause or
suffer to exist or become effective any consensual encumbrance or consensual
restriction of any kind on the ability of any Restricted Subsidiary to (i) pay
dividends or make any other distributions permitted by applicable law on any
Capital Stock of such Restricted Subsidiary owned by the Company or any other
Restricted Subsidiary, (ii) pay any Indebtedness owed to the Company or any
other Restricted Subsidiary, (iii) make loans or advances to the Company or any
other Restricted Subsidiary or (iv) transfer any of its property or assets to
the Company or any other Restricted Subsidiary.

          The foregoing provisions shall not restrict any encumbrances or
restrictions: (i) existing on the Issue Date, including those in this Indenture
or in the Existing Indebtedness, and any Permitted Refinancings thereof,
provided that the encumbrances and restrictions in any such Permitted
Refinancings are in the aggregate not materially more restrictive than those
encumbrances or restrictions that are then in effect and that are being
extended, refinanced, renewed or replaced; (ii) existing under or by reason of
applicable law and not due to any contractual arrangement; (iii) in the case of
clause (iv) of the first paragraph of this covenant, (A) that restrict in a
customary manner the subletting, assignment or transfer of any property or asset
that is a lease, license, conveyance or contract or similar property or asset,
(B) existing by virtue of any transfer of, agreement to transfer, option or
right with respect to, or Lien on, any property or assets of the Company or any
Restricted Subsidiary not otherwise prohibited by this Indenture, (C) arising or
agreed to in the ordinary course of business, not relating to any Indebtedness
for borrowed money, and that do not, individually or in the aggregate, detract
from the value of property or assets of the Company or any Restricted Subsidiary
in any manner material to the Company or any Restricted Subsidiary, (D) existing
pursuant to any purchase money obligations for property solely with respect to
the property acquired or (E) existing pursuant to any mortgage or construction
financing that imposes restrictions solely on the real property acquired or
improved; (iv) with respect to a Restricted Subsidiary and imposed pursuant to
an agreement that has been entered into for the sale or disposition of all or
substantially all of the Capital Stock of, or property or assets of, such
Restricted Subsidiary; or (v) included in Bank Indebtedness or Guarantees
incurred pursuant to clauses (iv) and (v) of the second paragraph of Section
4.08, respectively, so long as, in the case of this

                                      -58-

clause (v), the relevant restrictions in no event restrict payments to the
Company to be used by it to make payments of principal, interest or other
amounts as required pursuant to the terms of the Notes or this Indenture other
than to require that no such payment be made if there is a default or event of
default with respect to the Bank Indebtedness or Guarantees. Nothing contained
in this Section shall prevent the Company or any Restricted Subsidiary from (1)
creating, incurring, assuming or suffering to exist any Liens otherwise
permitted in Section 4.09 or (2) restricting the sale or other disposition of
property or assets of the Company or any of its Restricted Subsidiaries that
secure Indebtedness of the Company or any of its Restricted Subsidiaries.

property or assets, or the rendering of any service) with any legal or
beneficial owner (or any Affiliate of such holder) of 5% or more of any class of
Capital Stock of the Company or with any Affiliate of the Company or any
Restricted Subsidiary (each of the foregoing, an "Affiliate Transaction"),
unless: (i) such Affiliate Transaction is on terms that are no less favorable to
the Company or such Restricted Subsidiary than those that would have been
obtained at the time of such transaction or at the time of the execution of the
agreement providing therefor in a comparable arm's-length transaction with a
Person that is not such a Related Person and (ii) the Company delivers to the
Indenture Trustee: (x) with respect to any Affiliate Transaction involving
aggregate payments in excess of $250,000 but less than $2.5 million, a
resolution of the Board of Directors of the Company set forth in an Officers'

Certificate certifying that such Affiliate Transaction complies with clause (i)
above and (A) that such Affiliate Transaction has been approved by at least
three disinterested directors of the Board of Directors of the Company and, in
any case, by a majority of the disinterested directors of the Board of Directors
of the Company or (B) a written opinion as to the fairness to the Company or
such Restricted Subsidiary from a financial point of view issued by an
independent internationally recognized investment banking firm or independent
Colombian investment banking firm with respect to any such Affiliate
Transaction, and (z) with respect to any Affiliate Transaction involving
aggregate payments equal to or greater than $15.0 million, a resolution of the
Board of Directors of the Company set forth in an Officers' Certificate

<PAGE>
 
fairness to the Company or such Restricted Subsidiary from a financial point of
view issued by an independent internationally recognized investment banking firm
with respect to any such Affiliate Transaction.

          Notwithstanding the foregoing, the following shall not be deemed
Affiliate Transactions: (i) any transaction between the Company and any of its
Restricted Subsidiaries or between Restricted Subsidiaries, provided such
transaction complies with clause (i) in the first paragraph above (other than
for amounts paid by a Restricted Subsidiary to the Company in respect of
corporate overhead); (ii) the payment of reasonable and customary regular fees
to directors of the Company who are not employees of the Company; (iii) any
payments or other transactions pursuant to any tax-sharing agreement between the
Company and any other Person with which the Company files a consolidated tax
return or with which the Company is part of a consolidated group for tax

Company set forth in an Officer's Certificate certifying that such Affiliate
Transaction complies with clause (i) in the first paragraph above, and contains
terms substantially similar to the terms of Global I leases, Global II Leases
and Global III Leases, and any extension, amendment, replacement or renewal
thereof.


          Section 4.15. Limitation on Issuances of Guarantees by Restricted
Subsidiaries.

          The Company shall not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company ("Guaranteed
Indebtedness"), unless (i) such Restricted Subsidiary simultaneously executes
and delivers a Subsidiary Guarantee and (ii) such Restricted Subsidiary waives
and shall not in any manner whatsoever claim or take the benefit or advantage
of, any rights of reimbursement, indemnity or subrogation or any other rights
against the Company or any other Restricted Subsidiary as a result of any
payment by such Restricted Subsidiary under its Subsidiary Guarantee; provided
that this paragraph shall not be applicable to any Guarantee of any Restricted
Subsidiary that (A) (x) existed at the time such Person became a Restricted
Subsidiary and (y) was not incurred in connection with, or in contemplation of,
such Person becoming a Restricted Subsidiary or (B) Guarantees of Bank
Indebtedness incurred by the Company pursuant to clause (iv) of the second
paragraph of Section 4.08.  If the Guaranteed Indebtedness is (A) pari passu
with the

                                      -60-
<PAGE>
 
Notes, then the Guarantee of such Guaranteed Indebtedness shall be pari passu
with, or subordinated to, the Subsidiary Guarantee or (B) subordinated to the
Notes, then the Guarantee of such Guaranteed Indebtedness shall be subordinated
to the Subsidiary Guarantee at least to the extent that the Guaranteed
Indebtedness is subordinated to the Notes.

          Notwithstanding the foregoing, any Subsidiary Guarantee by a
Restricted Subsidiary shall provide by its terms that it shall be automatically
and unconditionally released and discharged upon (i) any sale, exchange or
transfer, to any Person not an Affiliate of the Company, of all of the Company's
and each Wholly-Owned Subsidiary's Capital Stock in such Restricted Subsidiary
(which sale, exchange or transfer is not prohibited by this Indenture) or (ii)
the release or discharge of the Guarantee or other Indebtedness which resulted
in the creation of such Subsidiary Guarantee, except a release or discharge by
or as a result of payment under such Guarantee.

          Under certain circumstances, the Company may cause the execution and
delivery of Subsidiary Guarantees.  Each Subsidiary Guarantee delivered by a
Restricted Subsidiary is limited to such amount as will not, after giving effect
thereto, and to all other liabilities of such Restricted Subsidiary, result in
such amount constituting a fraudulent transfer or conveyance.


          Section 4.16. Limitation on Modifications to Certain Documents.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to: (a) after the issuance thereof, amend or modify (or permit the

resulting from actual repayment to the Company in cash) the principal amount of
the Indebtedness evidenced thereunder, or (b) amend or modify any of the terms
or provisions of its estatutos sociales or other charter documents and, in the
case of the Restricted Subsidiaries, any lease agreement to which an Affiliate
of such Restricted Subsidiary or an Affiliate of the Company is a party, in any
manner adverse to the interests of the Holders.

indirectly, engage in any business other than the Telecommunications Business in
Latin America; provided that in the event a Change of Control occurs in which
one or more Strategic Equity Investors gain control of the Company this covenant

          (3)  that any Note not tendered will continue to accrue interest;

          (4)  that, unless the Company defaults in making payment therefor, any

     statement that such Holder is withdrawing his election to have such Notes
     purchased;

          (7)  that Holders whose Notes are purchased only in part will be
     issued new Notes in a principal amount equal to the unpurchased portion of

     new Note issued shall be in an original principal amount of $1,000 or
     integral multiples thereof; and

          (8)  the circumstances and relevant facts regarding such Change of

and the order or decree remains unstayed and in effect for 60 consecutive days.
The term "Custodian" means any receiver, trustee, assignee, liquidator or
similar official under any Bankruptcy Law;

          (j)    there occurs with respect to the Global I Purchase Agreement,
the Global II Purchase Agreement, the purchase agreements to be entered into in
connection with the Global III Leases, or any future Global arrangements
permitted under this Indenture an event of default that has caused Siemens to
declare Global's Obligations under such purchase agreements to be due and
payable prior to such Obligations' Stated Maturity and (A) such Obligations have
not been discharged in full, or (B) such acceleration has not been rescinded or
annulled within 10 days following such acceleration; and

          (k)    failure by Global to perform or comply with the Global
Undertaking Letter, or Global rejects being bound by the terms of the Global
Undertaking or repudiation by the Company of its obligations under the Escrow
and Disbursement Agreement for any reason.


          Section 6.02. Acceleration.

          If any Event of Default (other than an Event of Default specified in
clauses 6.01(h) that occurs with respect to the Company and (i) above) occurs
and is continuing under this Indenture, the Indenture Trustee or the Holders of
at least 25% in principal amount of the then outstanding Notes may declare all
the Notes to be immediately due and payable at 100% of the unpaid principal
thereof plus accrued and unpaid interest thereon, if any, by notice in writing
to the Company and the Indenture Trustee specifying the respective Event of
Default and that it is a "notice of acceleration" (the "Acceleration Notice").
Upon such declaration, the principal of, premium, if any, and accrued interest
on the Notes shall become immediately due and payable.  Notwithstanding the
foregoing, in the case of an Event of Default specified in clause (h) or (i)
with respect to the Company or (j) of Section 6.01, the foregoing amount shall
ipso facto become due and payable without further action or notice.  No premium
is payable upon acceleration of the Notes except that in the case of an Event of
Default that is the result of an action or inaction by the Company or any of its
Subsidiaries intended to avoid premiums related to redemptions of the Notes
contained in this Indenture or the Notes, the amount declared due and payable
will include the

                                      -68-
<PAGE>
 
premium that would have been applicable on a voluntary prepayment of the Notes
or, if voluntary prepayment is not then permitted, the premium set forth in this
Indenture.

          At any time after a declaration of acceleration with respect to the
Notes as described in the preceding paragraph, but before a judgment or decree
for the payment of money due has been obtained by the Indenture Trustee, the
Holders of at least a majority in principal amount of the Notes may rescind and
cancel such declaration and its consequences (i) if the rescission would not
conflict with any judgment or decree, (ii) if all existing Events of Default
have been cured or waived except non payment of principal or interest that has
become due solely because of the acceleration, (iii) to the extent the payment
of such interest is lawful, interest on overdue installments of interest and
overdue principal, which has become due otherwise than by such declaration of
acceleration, has been paid, (iv) if the Company has paid the Indenture Trustee
its reasonable compensation and reimbursed the Indenture Trustee for its
expenses, disbursements and advances and (v) in the event of the cure or waiver
of an Event of Default specified in clause (h) of Section 6.01, the Indenture
Trustee shall have received an Officers' Certificate and an Opinion of Counsel
that such Event of Default has been cured or waived.


          Section 6.03. Other Remedies.

          If an Event of Default occurs and is continuing, the Indenture Trustee
may pursue any available remedy to collect the payment of principal, premium, if
any, and interest on the Notes or to enforce the performance of any provision of
the Notes or this Indenture or the Escrow and Disbursement Agreement.

          The Indenture Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding.  A
delay or omission by the Indenture Trustee or any Holder of a Note in exercising
any right or remedy accruing upon an Event of Default shall not impair the right
or remedy or constitute a waiver of or acquiescence in the Event of Default.
All remedies are cumulative to the extent permitted by law.


          Section 6.04. Waiver of Past Defaults.

          The Holders of a majority in aggregate principal amount of the Notes
then outstanding, by notice to the Indenture Trustee, may on behalf of the
Holders of all of the Notes waive any existing Default or Event of Default and
its consequences under this Indenture, except a continuing Default or Event of
Default in the payment

                                      -69-
<PAGE>
 
of interest or premium on, or the principal of, the Notes, or in respect of a
covenant or a provision which cannot be amended or modified without the consent
of all Holders.

          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 impair any right consequent thereon.


          Section 6.05. Control by Majority.

          Subject to 2.09, holders of a majority in principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Indenture Trustee or
exercising any trust or power conferred on it. However, the Indenture Trustee
may refuse to follow any direction that conflicts with the law or this Indenture
that the Indenture Trustee determines may be unduly prejudicial to the rights of
other Holders of Notes or that may involve the Indenture Trustee in personal
liability.


          Section 6.06. Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

          (a)  the Holder of a Note gives to the Indenture Trustee written
notice of a continuing Event of Default,

          (b)  the Holders of at least 25% in principal amount of the then
outstanding Notes make a written request to the Indenture Trustee to pursue the
remedy;

          (c)  such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Indenture Trustee indemnity satisfactory to the
Indenture Trustee against any loss, liability or expense;

          (d)  the Indenture Trustee does not comply with the request within 15
days after receipt of the request and the offer and, if requested, the provision
of indemnity; and

                                      -70-
<PAGE>
 
          (e)  during such 15-day period the Holders of a majority in principal
amount of the then outstanding Notes do not give the Indenture Trustee a
direction inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another
Holder of a Note or to obtain a preference or priority over another Holder of a
Note.


          Section 6.07. Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal, premium, if any, and
interest on the Note, on or after the respective due dates expressed in the
Note, or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of the
Holder of the Note.


          Section 6.08. Collection Suit by Indenture Trustee.

          If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Indenture Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole
amount of principal of, premium, if any, and interest remaining unpaid on the
Notes and interest on overdue principal and, to the extent lawful, interest and
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 Indenture Trustee, its agents and counsel.


          Section 6.09. Indenture Trustee May File Proofs of Claim.

          The Indenture Trustee is authorized to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the
claims of the Indenture Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Indenture Trustee, its
agents and counsel) and the Holders of the Notes allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes), the
Company's creditors or the Company's property and shall be entitled and
empowered to participate as a member, voting or otherwise, of any official
committee of creditors appointed in such matter and to collect, receive and
distribute any money or other property payable or deliverable on any such claims
and any custodian in any such judicial proceeding is hereby authorized by each
Holder

                                      -71-
<PAGE>
 
of a Note to make such payments to the Indenture Trustee, and in the event that
the Indenture Trustee shall consent to the making of such payments directly to
the Holders of the Notes, to pay to the Indenture Trustee any amount due to it
for the reasonable compensation, expenses, disbursements and advances of the
Indenture Trustee, its agents and counsel, and any other amounts due the
Indenture Trustee under Section 7.07. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Indenture Trustee, its
agents and counsel, and any other amounts due the Indenture Trustee under
Section 7.07 out of the estate in any such proceeding, shall be denied for any
reason, payment of the same shall be secured by a Lien on, and shall be paid out
of, any and all distributions, dividends, money, securities and other properties
which the Holders of the Notes may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise.  Nothing herein contained shall be deemed to authorize the Indenture
Trustee to authorize or consent to or accept or adopt on behalf of any Holder of
a Note any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder of a Note thereof, or to
authorize the Indenture Trustee to vote in respect of the claim of any Holder of
a Note in any such proceeding.


          Section 6.10. Priorities.

          If the Indenture Trustee collects any money pursuant to this Article,
it shall pay out the money in the following order:

          First:    to the Indenture Trustee, the Agents, and their agents and
attorneys for amounts due under Section 7.07, including payment of all
compensation, expense and liabilities incurred, and all advances made, by the
Indenture Trustee and the costs and expenses of collection;

          Second:   to Holders of Notes, for amounts due and unpaid on such
Notes for principal, premium, if any, and interest, ratably, without preference
or priority of any kind to the extent of moneys and securities collected under
the Escrow and Disbursement Agreement according to the amounts due and payable
on the Notes for principal, premium, if any, and interest, respectively; and

          Third:    to the Company or to such party as a court of competent
jurisdiction shall direct.

          The Indenture Trustee may fix a record date and payment date for any
payment to Holders of Notes.

          Section 6.11.  Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Indenture Trustee for any action taken or
omitted by it as a Indenture Trustee, a court in its discretion may require the
filing by any party litigant in the suit of an undertaking to pay the costs of
the suit, and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant.  This Section does not apply to a suit by the Indenture Trustee, a
suit by a Holder of a Note pursuant to Section 6.07 or a suit by Holders of more
than 10% in principal amount of the then outstanding Notes.


                                   ARTICLE 7
                               INDENTURE TRUSTEE

          Section 7.01. Duties of Indenture Trustee.

          (a)   If an Event of Default has occurred and is continuing, the
Indenture Trustee shall exercise such of the rights and powers vested in it by
this Indenture, and use the same degree of care and skill in their exercise, as
a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

          (b)   Except during the continuance of an Event of Default:

          (i)   the duties of the Indenture Trustee and the Agents shall be
     determined solely by the express provisions of this Indenture and the
     Indenture Trustee and the Agents need perform only those duties that are
     specifically set forth in this Indenture and no others, and no implied
     covenants or obligations shall be read into this Indenture against the
     Indenture Trustee and the Agents, and

          (ii)  in the absence of bad faith on their part, the Indenture Trustee
     and the Agents may conclusively rely, as to the truth of the statements and
     the correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Indenture Trustee and the Agents and conforming
     to the requirements of this Indenture.  However, the Indenture Trustee
     shall examine the certificates and opinions to determine whether or not
     they conform to the requirements of this Indenture but shall not be
     obligated to verify the accuracy of the contents thereof.

                                      -73-
<PAGE>
 
          (c)    The Indenture Trustee may not be relieved from liabilities for
its own negligent action, its own negligent failure to act or its own willful
misconduct, except that:

          (i)    this paragraph does not limit the effect of paragraph (b) of
     this Section;

          (ii)   neither the Indenture Trustee nor any Agent shall be liable for
     any error of judgment made in good faith by a Responsible Officer, unless
     it is proved that the Indenture Trustee or such Agent was negligent in
     ascertaining the pertinent facts; and

          (iii)  the Indenture Trustee shall not be liable with respect to any
     action it takes or omits to take in good faith in accordance with a
     direction received by it pursuant to Section 6.05.

          (d)    Whether or not therein expressly so provided, every provision
of this Indenture that in any way relates to the Indenture Trustee or any Agent
is subject to paragraphs (a), (b), and (c) of this Section.

          (e)    No provision of this Indenture shall require the Indenture
Trustee to expend or risk its own funds or incur any liability. The Indenture
Trustee shall be under no obligation to exercise any of its rights and powers
under this Indenture at the request of any Holders of Notes, unless such Holder
shall have offered to the Indenture Trustee security and indemnity satisfactory
to the Indenture Trustee against any loss, liability or expense including
attorneys fees that might be incurred by it in compliance with such request or
direction.

          (f)    Neither the Indenture Trustee nor any Agent shall be liable for
interest on any money received by it except as the Indenture Trustee or such
Agent, as the case may be, may agree in writing with the Company.  Money held in
trust by the Indenture Trustee or such Agent, as the case may be, need not be
segregated from other funds except to the extent required by law.

          (g)    Each Holder of Notes, by its acceptance thereof, consents and
agrees to the terms of the Escrow and Disbursement Agreement as provided in
Section 10.01 and the Global Undertaking Letter.  Each Holder of Notes, by its
acceptance thereof, authorizes and directs the Indenture Trustee to enter into
the Escrow and Disbursement Agreement and the Global Undertaking Letter and to
perform its obligations and exercise its rights thereunder in accordance
therewith.

          Section 7.02.  Rights of Indenture Trustee.

          (a) The Indenture Trustee and each Agent may conclusively rely upon
any document believed by them to be genuine and to have been signed or presented
by the proper Person.  Neither the Indenture Trustee nor any Agent need
investigate any fact or matter stated in the document.

          (b) Before the Indenture Trustee or any Agent acts or refrains from
acting, it may require an Officers' Certificate or an Opinion of Counsel or
both.  Neither the Indenture Trustee nor any Agent shall be liable for any
action it takes or omits to take in good faith in reliance on such Officers'
Certificate or Opinion of Counsel.  The Indenture Trustee or any Agent may
consult with counsel and the advice of such counsel or any Opinion of Counsel
shall be full and complete authorization and protection from liability in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon.

          (c) The Indenture Trustee and any Agent may act through their
attorneys and agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care.

          (d) The Indenture Trustee and any Agent shall not be liable for any
action they take or omit to take in good faith which they believe to be
authorized or within their rights or powers conferred upon it by this Indenture.

          (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by two Officers of the Company.

          (f) The Indenture 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 unless such Holders shall have offered to the
Indenture Trustee reasonable security or indemnity against the costs, expenses
and liabilities that might be incurred by it in compliance with such request or
direction.


          Section 7.03.  Individual Rights of Indenture Trustee.

          The Indenture Trustee in its individual or any other capacity may
become the owner or pledge of Notes and may otherwise deal with the Company or
any Affiliate of the Company with the same rights it would have if it were not
Indenture Trustee, including (i) acting as escrow agent pursuant to the Escrow
and Disbursement

                                      -75-
<PAGE>
 
Agreement dated as of October 28, 1997 among the Indenture Trustee, in its
capacity as such and as escrow agent, and the Company, (ii) acting as collateral
agent pursuant to the Pledge Agreement, dated as of October 28, 1997, between
the Indenture Trustee, in its capacity as collateral agent, and the Company and
(iii) acting as Guarantee Trustee under the Guarantee (as defined in the Trust
Agreement).  However, in the event that the Indenture Trustee acquires any
conflicting interest it must eliminate such conflict within 90 days, apply to
the Commission for permission to continue as trustee or resign.  Any Agent may
do the same with like rights and duties.  The Indenture Trustee is also subject
to Sections 7.10 and 7.11.


          Section 7.04.  Indenture Trustee's Disclaimer.

          The Indenture Trustee and the Agents shall not be responsible for and
make no representation as to the validity or adequacy of this Indenture, the
Pledge Agreement, the Escrow and Disbursement Agreement, the Global Undertaking
Letter the Guarantee or the Notes, shall not be accountable for the Company's
use of the proceeds from the Notes or any money paid to the Company or upon the
Company's direction under any provision of this Indenture, shall not be
responsible for the use or application of any money received by any Paying Agent
other than the Indenture Trustee and shall not be responsible for any statement
or recital herein or any statement in the Notes or any other document in
connection with the sale of the Notes or pursuant to this Indenture other than
its certificate of authentication.


          Section 7.05.  Notice of Defaults.

          If a Default or Event of Default occurs and is continuing and if it is
known to a Responsible Officer of the Indenture Trustee, the Indenture Trustee
shall mail to Holders of Notes a notice of the Default or Event of Default
within 90 days after it occurs.  Except in the case of a Default or Event of
Default in payment of principal of, premium, if any, or interest on any Note,
the Indenture Trustee may withhold the notice if and so long as a committee of
its Responsible Officers in good faith determines that withholding the notice is
in the interests of the Holders of the Notes.


          Section 7.06.  Reports by Indenture Trustee to Holders of the Notes.

          Within 60 days after each April 15 beginning with the April 15
following the date of this Indenture, the Indenture Trustee shall mail to the
Holders of the Notes

                                      -76-
<PAGE>
 
a brief report dated as of such reporting date that complies with TIA (S) 313(a)
(but if no event described in TIA (S) 313(a) has occurred within the twelve
months preceding the reporting date, no report need be transmitted).  The
Indenture Trustee also shall comply with TIA (S) 313(b)(2).  The Indenture
Trustee shall also transmit by mail all reports as required by TIA (S) 313(c).

          A copy of each report at the time of its mailing, to the Holders of
Notes shall be mailed to the Company and filed with the Commission and each
stock exchange on which the Notes are listed.  The Company shall promptly notify
the Indenture Trustee when the Notes are listed on any stock exchange.


          Section 7.07.  Compensation and Indemnity.

          The Company shall pay to the Indenture Trustee and the Agents from
time to time reasonable compensation as agreed in writing from time to time for
their acceptance of this Indenture and services hereunder.  The Indenture
Trustee's and the Agents' compensation shall not be limited by any law on
compensation of a trustee of an express trust.  The Company shall reimburse the
Indenture Trustee and the Agents promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by them in addition to the
compensation for their services.  Such expenses shall include the reasonable
compensation, disbursements and expenses of the Indenture Trustee's and the
Agents' agents and counsel.

          The Company shall indemnify the Indenture Trustee and the Agents
against any and all losses, liabilities or expenses incurred by them arising out
of or in connection with the acceptance or administration of their duties under
this Indenture, the Notes, or the Escrow and Disbursement Agreement, except any
such loss, liability or expense as may be attributable to the negligence or bad
faith of the Indenture Trustee or such Agent.  The Indenture Trustee or such
Agent shall notify the Company promptly of any claim for which it may seek
indemnity.  Failure by the Indenture Trustee or such Agent to so notify the
Company shall not relieve the Company of its obligations hereunder.  The Company
shall defend the claim and the Indenture Trustee shall cooperate in the defense.
The Indenture Trustee may have separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel.  The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld.

          The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

                                      -77-
<PAGE>
 
          To secure the Company's payment obligations in this Section, the
Indenture Trustee and the Agents shall have a lien prior to the Notes on all
money or property held or collected by the Indenture Trustee and the Agents,
except that held in trust to pay principal, premium, if any, and interest on
particular Notes.  Such lien shall survive the satisfaction and discharge or
termination of this Indenture (including any termination under any Bankruptcy
Law) or the resignation or removal of any Agent or the Indenture Trustee, as the
case may be.

          When the Indenture Trustee or any Agent incurs expenses or renders
services after an Event of Default specified in Section 6.01(h) or (i) occurs,
the expenses and the compensation for the services (including the fees and
expenses of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law.


          Section 7.08.  Replacement of Indenture Trustee.

          A resignation or removal of the Indenture Trustee and appointment of a
successor Indenture Trustee shall become effective only upon the successor
Indenture Trustee's acceptance of appointment as provided in this Section.

          The Indenture Trustee may resign in writing at any time and be
discharged from the trust hereby created by so notifying the Company.  The
Holders of Notes of a majority in principal amount of the then outstanding Notes
may remove the Indenture Trustee by so notifying the Indenture Trustee and the
Company in writing.  The Company may remove the Indenture Trustee if:

          (a) the Indenture Trustee falls to comply with Section 7.10;

          (b) the Indenture Trustee is adjudged a bankrupt or an insolvent or an
     order for relief is entered with respect to the Indenture Trustee under any
     Bankruptcy Law;

          (c) a Custodian or public officer takes charge of the Indenture
     Trustee or its property; or

          (d) the Indenture Trustee becomes incapable of acting,

          If the Indenture Trustee resigns or is removed or if a vacancy exists
in the office of Indenture Trustee for any reason, the Company shall promptly
appoint a successor Indenture Trustee.  Within one year after the successor
Indenture Trustee

                                      -78-
<PAGE>
 
takes office, the Holders of a majority in principal amount of the then
outstanding Notes may appoint a successor Indenture Trustee to replace the
successor Indenture Trustee appointed by the Company.

          If a successor Indenture Trustee does not take office within 60 days
after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Company, or the Holders of Notes of at least 10% in
principal amount of the then outstanding Notes may petition any court of
competent jurisdiction for the appointment of a successor Indenture Trustee.

          If the Indenture Trustee after written request by any Holder of a Note
who has been a Holder of a Note for at least six months fails to comply with
Section 7.10, such Holder of a Note may petition any court of competent
Jurisdiction for the removal of the Indenture Trustee and the appointment of a
successor Indenture Trustee.

          A successor Indenture Trustee shall deliver a written acceptance of
its appointment to the retiring Indenture Trustee and to the Company.
Thereupon, the resignation or removal of the retiring Indenture Trustee shall
become effective, and the successor Indenture Trustee shall have all the rights,
powers and duties of the Indenture Trustee under this Indenture.  The successor
Indenture Trustee shall mail a notice of its succession to Holders of the Notes.
The retiring Indenture Trustee shall promptly transfer all property held by it
as Indenture Trustee to the successor Indenture Trustee, provided all sums owing
to the Indenture Trustee hereunder have been paid and subject to the Lien
provided for in Section 7.07.  Notwithstanding replacement of the Indenture
Trustee pursuant to this Section 7.08, the Company's obligations under Section
7.07 shall continue for the benefit of the retiring Indenture Trustee.


          Section 7.09.  Successor Indenture Trustee by Merger, etc.

          If the Indenture Trustee consolidates, merces or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor Indenture Trustee.


          Section 7.10.  Eligibility; Disqualification.

          There shall at all times be an Indenture Trustee hereunder which shall

corporate trustee

                                      -79-

power, shall be subject to supervision or examination by Federal or state
authority and shall have a combined capital and surplus of at least $25 million
as set forth in its most recent published annual report of condition.

          This Indenture shall always have a Indenture Trustee who satisfies the
requirements of TIA (S) 310(a)(1), (2) and (5).  The Indenture Trustee is
subject to TIA (S) 310(b).


          Section 7.11.  Preferential Collection of Claims Against Company.

          The Indenture Trustee is subject to TIA (S) 311(a), excluding any
creditor relationship listed in TIA (S) 311(b).  A Indenture Trustee who has
resigned or been removed shall be subject to TIA (S) 311(a) to the extent
indicated therein.


          Section 7.12.  Appointment of Co-Trustee or Separate Trustee

          Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction the Indenture
Trustee shall have the power and shall execute and deliver all instruments to
appoint one or more Persons to act (at the expense of the Company) as co-trustee
or co-trustees, jointly with the Indenture Trustee, or to act as separate
trustee or separate trustees, and to vest in such Person or Persons, in such
capacity, such title to the property of the Trust, or any part thereof, and,
subject to the other provisions of this Section 7.12, such powers, duties,
obligations, rights and trusts as the Indenture Trustee may consider necessary
or desirable.  Except as required by applicable law, the appointment of a co-
trustee or separate trustee shall not relieve the Indenture Trustee of its
responsibilities hereunder.  No co-trustee or separate trustee hereunder shall
be required to meet the terms of eligibility as a successor Trustee under
Section 7.09 hereunder and no notice to Holders of Notes of the appointment of
co-trustee(s) or separate trustee(s) shall be required hereunder.

          In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 7.12, all rights, powers, duties and obligations
conferred or imposed upon the Indenture Trustee shall be conferred or imposed
upon and exercised or performed by the Indenture Trustee and such separate
trustee or co-trustee jointly (it being understood that such separate trustee or
co-trustee is not authorized to act separately without the Indenture Trustee
joining in such act), except to the extent that under any law of any
jurisdiction in which any particular act or acts are to be performed, the
Indenture Trustee shall be incompetent or unqualified to perform such

                                      -80-
<PAGE>
 
act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the property of the Trust or any portion
thereof in any such jurisdiction) shall be exercised and performed by such
separate trustee or co-trustee solely at the direction of the Indenture Trustee.

          No trustee under this Indenture shall be personally liable by reason
of any act or omission of any other trustee under this Indenture, unless such
act or omission results from the negligence or willful misconduct of such
trustee.  The Indenture Trustee may at any time accept the resignation of or
remove any separate trustee or co-trustee.

          Any notice, request or other writing given to the Indenture Trustee
shall be deemed to have been given to each of the then separate trustees and co-
trustees, as effectively as if given to each of them.  Every instrument
appointing any separate trustee or co-trustee shall refer to this Indenture and
the conditions of this Article 7.  Every such instrument shall be filed with the
Indenture Trustee.  Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Indenture Trustee or
separately, as may be provided therein, subject to all the provisions of this
Indenture, specifically including every provision of this Indenture relating to
the conduct of, affecting the liability of, or affording protection to, the
Indenture Trustee.

          Any separate trustee or co-trustee may, at any time, constitute the
Indenture Trustee its agent or attorney-in-fact, with full power and authority,
to the extent not prohibited by law, to do any lawful act under or in respect of
this Indenture on its behalf and in its name.  If any separate trustee or co-
trustee shall die, become incapable of acting, resign or be removed, all of its
estates, properties, rights, remedies and trusts shall vest in and be exercised
by the Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.  The appointment of a co-trustee or
separate trustee shall not relieve the Indenture Trustee of its duties
hereunder.

          Section 8.01.  Satisfaction and Discharge of Indenture.

          This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Notes herein

provided for), and the Indenture Trustee, on demand of and at the expense of the
Company, shall execute instruments in form and substance satisfactory to the
Indenture Trustee and the Company acknowledging satisfaction and discharge of
this Indenture, when

          (1)  either

               (A)  the Company shall have irrevocably paid in full all

          Guarantee) to the Guarantee Trustee (as such term is defined in the
          Certificate Guarantee) pursuant to the terms of the Certificate
          Guarantee; or

               (B)  all Notes theretofore authenticated and issued (other than
          (i) Notes which have been destroyed, lost or stolen and which have
          been replaced or paid as provided in Section 2.07 and (ii) Notes for
          whose payment money has theretofore been deposited in trust or
          segregated and held in trust by the Company and thereafter repaid to
          the Indenture Trustee or discharged from such trust, as provided in
          Section 2.04) have been delivered to the Indenture Trustee for
          cancellation; or

               (C)  all such Notes not theretofore delivered to the Indenture
          Trustee for cancellation

               (i)  have become due and payable; or

               (ii) will become due and payable within one year,

          and the Company, in the case of (C)(i) or (ii) above, has deposited or
          caused to be deposited with the Indenture Trustee as trust funds in
          trust an amount sufficient to pay and discharge the entire
          indebtedness on such Notes not theretofore delivered to the Indenture
          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) together with irrevocable
          instructions from the Company directing the Indenture Trustee to apply
          such funds to the payment thereof at maturity or redemption, 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 Indenture 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 Indenture Trustee and the Agents under Section
7.07, the obligations of the Indenture Trustee to any Authenticating Agent under
Section 2.02 and, if money shall have been deposited with the Indenture Trustee
pursuant to subclause (C) of clause (1) of this Section 8.01, the obligations of
the Indenture Trustee under Section 7.05 shall survive.


          Section 8.02.  Application of Monies for Satisfaction and Discharge.

          All money deposited with the Indenture Trustee pursuant to Section
8.01 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
Indenture Trustee may determine, to the Persons entitled thereto, of the
principal and interest for whose payment such money has been deposited with the
Indenture Trustee.

                        AMENDMENT, SUPPLEMENT AND WAIVER

          Section 9.01.  Without Consent of Holders of Notes.

          From time to time, the Company and the Indenture Trustee, without the
consent of the Holders of the Notes, may amend this Indenture for the following
purposes, so long as such change does not adversely affect the rights of any of
the Holders.  The Indenture Trustee will be entitled to rely on such evidence as
it deems appropriate, including, without limitation, solely on an Opinion of
Counsel that such change does not adversely affect the rights of any Holder, in
executing any supplemental indenture.

          Notwithstanding Section 9.02 of this Indenture, the Company and the
Indenture Trustee may amend or supplement this Indenture, the Notes or the
Escrow and Disbursement Agreement without the consent of any Holder of a Note:

          (a) to cure any ambiguity, defect or inconsistency;

                                      -83-
<PAGE>
 
          (b) to provide for uncertificated Notes in addition to or in place of
certificated Notes;

          (c) to provide for the assumption of the Company's obligations to the
Holders of the Notes in the case of a merger or consolidation pursuant to
Article 5;

          (d) to execute and deliver any documents necessary or appropriate to
release Liens on the Escrow Account and the Refinancing Account as permitted by
Section 10.03;

          (e) to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights hereunder of any Holder of the Notes; or

          (f) to comply with requirements of the Commission in order to effect
or maintain the qualification of this Indenture under the TIA.

Upon the written request of the Company accompanied by a resolution of the Board
of Directors of the Company authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Indenture Trustee of the
documents described in Section 9.06, the Indenture Trustee shall join with the
Company in the execution of any amended or supplemental Indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate
agreements and stipulations which may be therein contained, but the Indenture
Trustee shall not be obligated to enter into such amended or supplemental
Indenture which affects its own rights, duties or immunities under this
Indenture or otherwise.


          Section 9.02.  With Consent of Holders of Notes.

          The Company and the Indenture Trustee may amend or supplement this
Indenture, the Notes or the Escrow and Disbursement Agreement or any amended or
supplemental Indenture with the written consent of the Holders of Notes of not
less than a majority in aggregate principal amount of the Notes then
outstanding, and any existing Default and its consequences or compliance with
any provision of this Indenture, the Notes or the Escrow and Disbursement
Agreement may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding Notes.

          Upon the request of the Company accompanied by a resolution of the
Board of Directors of the Company authorizing the execution of any such amended
or supplemental Indenture, and upon the filing with the Indenture Trustee of
evidence

                                      -84-
<PAGE>
 
satisfactory to the Indenture Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Indenture Trustee of the documents described
in Section 9.06, the Indenture Trustee shall join with the Company in the
execution of such amended or supplemental Indenture unless such amended or
supplemental Indenture affects the Indenture Trustee's own rights, duties or
immunities under this Indenture or otherwise, in which case the Indenture
Trustee may in its discretion, but shall not be obligated to, enter into such
amended or supplemental Indenture.

          It shall not be necessary for the consent of the Holders of Notes
under this Section 9.02 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

          After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver.  Any failure of
the Company to mail such amended notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amended or
supplemental Indenture or waiver.  Subject to Sections 6.04 and 6.07, the
Holders of a majority in aggregate principal amount of the Notes then
outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes.  However, without the consent of
each Holder affected thereby, an amendment or waiver may not (with respect to
any Notes held by a non-consenting Holder of Notes):

          (a) reduce the principal amount of Notes whose Holders must consent to
     an amendment, supplement or waiver;

          (b) reduce the principal of or change or have the effect of changing
     the fixed maturity of any Note or change the date on which any Note may be
     subject to redemption or repurchase, or reduce the redemption or repurchase
     price thereof;

          (c) reduce the rate of or change or have the effect of changing the
     time for payment of interest, including defaulted interest, on any Notes;

          (d) waive a Default or Event of Default in the payment of principal of
     or premium, if any, or interest on the Notes (except a rescission of
     acceleration of the Notes by the Holders of at least a majority in
     aggregate principal amount of the Notes and a waiver of the payment default
     relating solely to the principal or interest that has become due solely
     because of the acceleration);

                                      -85-
<PAGE>
 
          (e) make any Note payable in money other than that stated in the
     Notes;

          (f) make any change in the provisions of this Indenture relating to
     waivers of past Defaults or the rights of Holders of Notes to receive
     payments of principal of or interest on the Notes on or after the due date
     thereof or to bring suit to enforce such payment;

          (g) waive a redemption payment with respect to any Note (other than a
     payment required by Section 4.12 and 4.18);

          (h) amend, change or modify in any material respect the obligation of
     the Company to make and consummate a Change of Control Offer in the event
     of a Change of Control or make and consummate a Net Proceeds Offer with
     respect to any Asset Sale that has been consummated or modify any of the
     provisions or definitions with respect thereto;

          (i) make any change in the foregoing amendment and waiver provisions;
     or

          (j) directly or indirectly release Liens on all or substantially all
     of the collateral except as permitted by the Escrow and Disbursement
     Agreement.


          Section 9.03.  Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes shall be
set forth in an amended or supplemental Indenture that complies with the TIA as
then in effect.


          Section 9.04.  Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note.  However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Indenture Trustee receives
written notice of revocation before the date the waiver, supplement or amendment
becomes effective.  An

                                      -86-
<PAGE>
 
amendment, supplement or waiver becomes effective in accordance with its terms
and thereafter binds every Holder of a Note.

          The Company may fix a record date for determining which Holders of the
Notes must consent to such amendment, supplement or waiver.  If the Company
fixes a record date, the record date shall be fixed at (i) the later of 30 days
prior to the first solicitation of such consent or the date of the most recent
list of Holders of Notes furnished to the Indenture Trustee prior to such
solicitation pursuant to Section 2.05 or (ii) such other date as the Company
shall designate.


          Section 9.05.  Notation on or Exchange of Notes.

          The Indenture Trustee may place an appropriate notation about an
amendment, supplement or waiver on any Note thereafter authenticated.  The
Company in exchange for all Notes may issue and the Indenture Trustee shall
authenticate new Notes that reflect the amendment, supplement or waiver.

          Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.


          Section 9.06.  Indenture Trustee to Sign Amendments, etc.

          The Indenture Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Indenture
Trustee.  If it does, the Indenture Trustee may but need not sign it.  In
signing such amendment the Indenture Trustee shall be entitled to receive
indemnity reasonably satisfactory to it and to receive, and (subject to Section
7.01) shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel stating that such amendment is authorized or permitted by
this Indenture.


                                   ARTICLE 10

          Section 10.01.  Escrow and Disbursement Agreement.

Notes when and as the same shall be due and payable, whether on an Interest
Payment

Date, at the Stated Maturity, by acceleration, repurchase, redemption or
otherwise, and interest on the overdue principal of and interest (to the extent
permitted by law), if any, on the Notes and performance of all other obligations
of the Company to the Holders of Notes or the Indenture Trustee under this
Indenture with respect to the Notes, and the Notes, according to the terms
hereunder or thereunder, shall be secured as provided in the Escrow and
Disbursement Agreement which the Company, the Escrow Agent and the Indenture
Trustee have entered into simultaneously with the execution of this Indenture.
Each Holder of Notes, by its acceptance thereof, consents and agrees to the
terms of the Escrow and Disbursement Agreement (including, without limitation,
the provisions providing for foreclosure and disbursement of the amounts
deposited in the Escrow Account or the Refinancing Account) as the same may be
in effect or may be amended from time to time in accordance with its terms and
authorizes and directs the Escrow Agent and the Indenture Trustee to enter into
the Escrow and Disbursement Agreement and to perform its obligations and
exercise its rights thereunder in accordance therewith.  The Company shall
deliver to the Indenture Trustee copies of the Escrow and Disbursement
Agreement, and shall do or cause to be done all such acts and things as may be
necessary or proper, or as may be required by the provisions of the Escrow and
Disbursement Agreement, to assure and confirm to the Indenture Trustee the
security interest in the Escrow Account and the Refinancing Account contemplated
by the Escrow and Disbursement Agreement or any part thereof, as from time to
time constituted, so as to render the same available for the security and
benefit of this Indenture with respect to, and of, the Notes, according to the
intent and purposes expressed in the Escrow and Disbursement Agreement.  The
Company shall take any and all actions reasonably required to cause the Escrow
and Disbursement Agreement to create and maintain (to the extent possible under
applicable law), as security for the obligations of the Company hereunder, a
valid and enforceable perfected first priority Lien in and on all the amounts
deposited in the Escrow Account and Refinancing Account, in favor of the
Indenture Trustee for the benefit of the Holders of Notes, superior to and prior
to the rights of all third Persons and subject to no other Liens.


          Section 10.02.  Recording and Opinions.

          (a) The Company shall furnish to the Indenture Trustee simultaneously
with the execution and delivery of this Indenture an Opinion of Counsel either

respect to the recording, registering and filing of this Indenture, financing
statements or other instruments necessary to make effective the Lien intended to
be created by the Escrow and Disbursement Agreement, and reciting with respect
to the security interests in the Escrow Account and Refinancing Account, the
details of such action, or (ii)

                                      -88-

stating that, in the opinion of such counsel, no such action is necessary to
make such Lien effective.

          (b) The Company shall furnish to the Escrow Agent and the Indenture
Trustee on October 28, 1997, and on each October 28 thereafter until the date
upon which the balance of Escrow Account Available Funds and Refinancing Account
Available Funds shall have been reduced to zero, an Opinion of Counsel, dated as
of such date, either (i) stating that (A) in the opinion of such counsel, action
has been taken with respect to the recording, registering, filing, re-recording,
re-registering and refiling of all supplemental indentures, financing
statements, continuation statements or other instruments of further assurance as
is necessary to maintain the Lien of the Escrow and Disbursement Agreement and
reciting with respect to the security interests in the Escrow Account and the
Refinancing Account the details of such action or referring to prior Opinions of
Counsel in which such details are given and (B) based on relevant laws as in
effect on the date of such Opinion of Counsel, all financing statements and
continuation statements have been executed and filed that are necessary as of
such date and during the succeeding 12 months fully to preserve and protect, to
the extent such protection and preservation are possible by filing, the rights
of the Holders of Notes and the Indenture Trustee hereunder and under the Escrow
and Disbursement Agreement with respect to the security interests in the Escrow
Account and the Refinancing Account or (ii) stating that, in the opinion of such
counsel, no such action is necessary to maintain such Lien and assignment.


          Section 10.03.  Release of Amounts Deposited in the Escrow Account or
the Refinancing Account.

          (a) Subject to subsections (b), (c) and (d) of this Section 10.03,
amounts in the Escrow Account or the Refinancing Account may be released from
the Lien and security interest created by the Escrow and Disbursement Agreement
only in accordance with the provisions of the Escrow and Disbursement Agreement.

          (b) Except to the extent that any Lien on proceeds of the Escrow
Account or the Refinancing Account is automatically released by operation of
Section 9-306 of the Uniform Commercial Code or other similar law, no amounts
deposited in the Escrow Account or the Refinancing Account shall be released
from the Lien and security interest created by the Escrow and Disbursement
Agreement pursuant to the provisions of the Escrow and Disbursement Agreement,
other than pursuant to the terms thereof, unless there shall have been delivered
to the Indenture Trustee the certificate required by Section 10.03(d) and
Section 10.04.

                                      -89-

          (c) At any time when an Event of Default shall have occurred and be
continuing and the maturity of the Notes issued on the Issue Date shall have
been accelerated (whether by declaration or otherwise), no amounts deposited in
the Escrow Account or the Refinancing Account shall be released pursuant to the
provisions of the Escrow and Disbursement Agreement, and no release of amounts
deposited in the Escrow Account or the Refinancing Account in contravention of
this Section 10.03(c) shall be effective as against the Holders of Notes, except
for the disbursement of all Escrow Account Available Funds and Refinancing
Account Available Funds to the Indenture Trustee pursuant to Section 6(b) of the
Escrow and Disbursement Agreement.

          (d) The release of any amounts deposited in the Escrow Account or the
Refinancing Account from the Liens and security interests created by this
Indenture and the Escrow and Disbursement Agreement shall not be deemed to
impair the security under this Indenture in contravention of the provisions
hereof if and to the extent the amounts deposited in the Escrow Account or the
Refinancing Account are released pursuant to the terms hereof or, subject to
complying with the requirements of this Section 10.03, pursuant to the terms of
the Escrow and Disbursement Agreement.  To the extent applicable, the Company
shall cause TIA (S) 314(d) relating to the release of property or securities
from the Lien and security interest of the Escrow and Disbursement Agreement to
be complied with.  Any certificate or opinion required by TIA (S) 314(d) may be
made by an Officer of the Company except in cases where TIA (S) 314(d) requires
that such certificate or opinion be made by an independent Person, which Person
shall be an independent engineer, appraiser or other expert selected or approved
by the Indenture Trustee in the exercise of reasonable care.


          Section 10.04.  Certificates of the Company.

          The Company shall furnish to the Indenture Trustee, prior to any
proposed release of the amounts in the Escrow Account or the Refinancing Account
other than pursuant to the express terms of the Escrow and Disbursement
Agreement, (i) all documents required by Section 314(d) of the TIA and (ii) an
Opinion of Counsel, which may be rendered by internal counsel to the Company, to
the effect that such accompanying documents constitute all documents required by
Section 314(d) of the TIA.  The Indenture Trustee may, to the extent permitted
by Sections 7.01 and 7.02, accept as conclusive evidence of compliance with the
foregoing provisions the appropriate statements contained in such documents and
such Opinion of Counsel.

          Section 10.05.  Authorization of Actions to be Taken by the Indenture
Trustee Under the Escrow and Disbursement Agreement.

          Subject to the provisions of Section 7.01 and 7.02, the Indenture
Trustee may, without the consent of the Holders of Notes, on behalf of the
Holders of Notes, take all actions it deems necessary or appropriate in order to

"Trust").  The Trust will purchase the Notes with the proceeds of the sale of
its 12 1/2% Pass Through Trust Certificates due 2007 (the "Certificates").

law of the Republic of Colombia (the "Company"), promises to pay interest on the
principal amount of this Note at the rate per annum shown above.  If the Company
fails to fulfill its obligations under Section 2 or Section 3 of the
Registration Rights Agreement, dated as of October 28, 1997, among the Company,
the Trust and the Initial Purchaser (as defined in the Indenture) (the
"Registration Rights Agreement"), the Company shall pay, as liquidated damages,
additional interest on the Notes ("Additional Interest") as follows (each such
                                   -------------------                        
event referred to in clauses (i) through (iii) below, a "Registration Default"
                                                         -------------------- 
and each of which shall be given independent effect):

          (i)   if the Exchange Offer Registration Statement (as defined in the
     Registration Rights Agreement) has not been filed on or prior to the 150th
     day following the Issue Date, then commencing on the 151st day after the
     Issue Date, Additional Interest shall accrue on the Notes over and above
     the accrued interest at a rate of 0.50% per annum for the first 90 days
     immediately following such 151st day;

          (ii)  if the Exchange Offer Registration Statement is not declared
     effective by the SEC on or prior to the 210th day following the Issue Date,
     then commencing on the 211th day after the Issue Date, Additional Interest
     shall accrue on the Notes included or which should have been included in
     such Registration Statement over and above the accrued interest at a rate
     of 0.50% per annum for the first 90 days immediately following such 211th
     day; and

          (iii) if (A) the Trust has not exchanged Exchange Certificates (as
     defined in the Registration Rights Agreement) for all Certificates validly
     tendered in accordance with the terms of the Exchange Offer (as defined in
     the Registration Rights Agreement), (B) the Shelf Registration Statement
     (as defined in the Registration Rights Agreement) is not filed on or prior
     to the 30th day following delivery of the Shelf Notice (as defined in the
     Registration Rights Agreement), (C) the Shelf Registration Statement is not
     declared effective on or prior to the 60th day following the delivery of
     the Shelf Notice or (D) the Exchange Offer Registration Statement or the
     Shelf Registration Statement, as the case may be, has been declared
     effective and ceases to be effective, then Additional Interest shall accrue
     on the

                                      A-4
<PAGE>
 
     Notes over and above the accrued interest at a rate of 0.50% per annum for
     the first 90 days commencing on the day after such Registration Default;

such Additional Interest rate, in the case of each of (i), (ii) and (iii) above,
to increase by an additional 0.50% per annum at the beginning of each subsequent
90-day period; provided, however, that in no event shall the amount of
               --------  -------                                      
Additional Interest exceed 2.00% in the aggregate pursuant to this Section 1;
provided further, that (1) upon the filing of the Exchange Offer Registration
- ----------------                                                             
Statement (in the case of clause (i) of this Section 1), (2) upon the
effectiveness of the Exchange Offer Registration Statement (in the case of
clause (ii) of this Section 1), or (3) upon the exchange of Exchange
Certificates for all Certificates tendered (in the case of clause (iii)(A) of
this Section 1), the filing of the Shelf Registration Statement (in the case of
clause (iii)(B) of this Section 1), the effectiveness of the Shelf Registration
Statement (in the case of clause (iii)(C) of this Section 1), or upon the
effectiveness of the Exchange Offer Registration Statement or the Shelf
Registration Statement, as the case may be, which had ceased to remain effective
(in the case of clause (iii)(D) of this Section 1), Additional Interest on the
Notes as a result of such clause (or the relevant subclause thereof), as the
case may be, shall cease to accrue; provided, however, that at such time as the
Shelf Registration Statement or the Exchange Offer Registration Statement, as
the case may be, shall again cease to remain effective, Additional Interest
shall resume to accrue in the manner and for the time periods specified above.

          Interest on the Notes will accrue from the most recent date on which
interest has been paid or, if no interest has been paid, from October 28, 1997.
The Company will pay interest and Additional Interest, if any, semi-annually in
arrears on each Interest Payment Date, commencing May 1, 1998.  Interest will be
computed on the basis of a 360-year of twelve 30-day months and, in the case of
a partial month, the actual number of days elapsed.  The Company shall pay
interest on overdue principal and on overdue installments of interest (without
regard to any applicable grace periods) from time to time on demand at the rate
borne by the Notes plus 2% per annum, to the extent lawful.

          2.   Method of Payment.  The Company shall pay interest on the Notes
(except defaulted interest) or on Additional Interest, if any, in respect of the
Notes to the Persons who are the registered Holders at the close of business on
the Record Date immediately preceding the Interest Payment Date even if the
Notes are canceled on registration of transfer or registration of exchange after
such Record Date.  Holders must surrender Notes to a Paying Agent to collect
principal payments.  The Company shall pay principal and interest in money of
the United States that at the time of payment is legal tender for payment of
public and private debts ("U.S. Legal Tender").  However, the Company may pay
principal and interest by its check payable in such U.S. Legal Tender.  The
Company may deliver any such interest payment to the Paying Agent or to a Holder
at the Holder's registered address.

Midland Bank, as Indenture Trustee (the "Indenture Trustee").  This Note is one
of a duly authorized issue of Notes of the Company designated as its 12 1/2%

the Indenture.  Notwithstanding anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to the Indenture
and said Act for a statement of them.  The Notes are general unsecured
obligations of the Company.

          5.  Optional Redemption. (a) The Notes will not be redeemable at the

Company prior to November 1, 2000 of at least $25.0 million of its Capital Stock
(other than Disqualified Stock) in one or more Public Equity Offerings, or to
one or more Strategic Equity Investors, the Company may, at its option, use the
Net Cash Proceeds of such sale or sales of Capital Stock to redeem up to 35% of
the Notes at a redemption price equal to 112.50% of the principal amount thereof
plus accrued and unpaid interest thereon, if any, to the date of redemption;
provided that at least 65% of the initial principal amount of the Notes
(including in such initial principal amount, the initial principal amount of any
Additional Notes issued as contemplated by Section 2.02 of the Indenture, if
issued prior to the date of redemption pursuant to this paragraph) remains
outstanding immediately after such redemption.  In

                                      A-6
<PAGE>
 
order to effect the foregoing redemption with the proceeds of any such sale of
Capital Stock (other than Disqualified Stock), the Company shall make such
redemption not more than 120 days after the consummation of any such sale of
Capital Stock.

          The Notes are not entitled to the benefit of any sinking fund.

          6.   Notice of Redemption.  Notice of 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 registered address.  Notes in
denominations larger than $1,000 may be redeemed in part.

          Except as set forth in the Indenture, if monies for the redemption of
the Notes called for redemption shall have been deposited with the Paying Agent
for redemption on such Redemption Date, then, unless the Company defaults in the
payment of such Redemption Price plus accrued interest, if any, the Notes called
for redemption will cease to bear interest from and after such Redemption Date
and the only right of the Holders of such Notes will be to receive payment of
the Redemption Price plus accrued interest, if any.

          7.   Offers to Purchase.  Sections 4.12 and 4.18 of the Indenture
provide that, after certain Asset Sales (as defined in the Indenture) and upon
the occurrence of a Change of Control (as defined in the Indenture) subject to
further limitations contained therein, the Company will make an offer to
purchase certain amounts of the Notes in accordance with the procedures set
forth in the Indenture.

          8.   Denominations; Transfer; Exchange.  The Notes are in registered
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000.  A Holder shall register the transfer of or exchange 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 certain
transfer taxes or similar governmental charges payable in connection therewith
as permitted by the Indenture.  The Registrar need not resister the transfer of
or exchange of any Notes or portions thereof selected for redemption.

          9.   Persons Deemed Owners.  The registered Holder of a Note shall be
treated as the owner of it for all purposes.

          10.  Unclaimed Money.  If money for the payment of principal or
interest remains unclaimed for two years after such principal or interest has
become due and payable, the Indenture Trustee and the Paying Agent will pay such
money back to the Company.  After that, all liability of the Indenture Trustee
and such Paying Agent with respect to such money shall cease.

          11.  Discharge Prior to Redemption or Maturity.  If the Company at any
time deposits with the Indenture Trustee U.S. Legal Tender or U.S. Government
Obligations sufficient

                                      A-7

to pay the principal of and interest on the Notes to redemption or maturity and
complies with the other provisions of the Indenture relating thereto, the
Company will be discharged from certain provisions of the Indenture and the
Notes (including certain covenants, but excluding its obligation to pay the
principal of and interest on the Notes).

          12.  Amendment; Supplement; Waiver.  Subject to certain exceptions set
forth in the Indenture, the Indenture or the Notes may be amended or
supplemented with the written consent of the Holders of not less than a majority
in aggregate principal amount of the Notes then outstanding, and any past
Default or Event of Default or noncompliance with any provision may be waived
with the written consent of the Holders of not less than a majority in aggregate
principal amount of the Notes then outstanding.  Without notice to or consent of
any Holder, the parties thereto may amend or supplement the Indenture or the
Notes to, among, other things, cure any ambiguity, defect or inconsistency,
provide for uncertificated Notes in addition to or in place of certificated
Notes, or comply with Article 5 of the Indenture or make any other change that
does not adversely affect the rights of any Holder of a Note.

          13.  Restrictive Covenants.  The Indenture imposes certain limitations
on the ability of the Company and its Subsidiaries to, among other things, incur
additional Indebtedness, make payments in respect of its Capital Stock or
certain Indebtedness, make certain Investments, incur liens, enter into
transactions with Affiliates, create dividend or other payment restrictions
affecting Subsidiaries, issue Preferred Stock of its Subsidiaries, merge or
consolidate with any other Person, sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its assets or adopt a plan of
liquidation.  Such limitations are subject to a number of important
qualifications and exceptions.  Pursuant to Section 4.04 of the Indenture, the
Company must annually report to the Indenture Trustee on compliance with such
limitations.

          14.  Successors.  When a successor assumes, in accordance with the
Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor, subject to certain exceptions, will be released from
those obligations.

          15.  Defaults and Remedies.  If an Event of Default occurs and is
continuing, the Indenture Trustee or the Holders of not less than 25% in
aggregate principal amount of Notes then outstanding may declare all the Notes
to be due and payable in the manner, at the time and with the effect provided in
the Indenture.  Holders of Notes may not enforce the Indenture or the Notes
except as provided in the Indenture.  The Indenture Trustee is not obligated to
enforce the Indenture or the Notes unless it has received indemnity reasonably
satisfactory to it.  The Indenture permits, subject to certain limitations
therein provided, Holders of a majority in aggregate principal amount of the
Notes then outstanding to direct the Indenture Trustee in its exercise of any
trust or power.  The Indenture Trustee may withhold from Holders of Notes notice
of any continuing Default or Event of Default (except a Default in payment of
principal or interest when due, for any reason or a Default in compliance with
Article 5 of the Indenture) if it determines that withholding notice is in their
interest.

under the Indenture, in its individual or an other capacity, may become the
owner or pledgee of Notes and may otherwise deal with the Company, its
Subsidiaries or their respective Affiliates as if it were not the Indenture
Trustee.

          17.  No Recourse Against Others.  No stockholder, director, officer,
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of, such obligations or their creation.
Each Holder of a Note by accepting a Note waives and releases all such
liability.  The waiver and release are part of the consideration for the
issuance of the Notes.

          18.  Authentication.  This Note shall not be valid until the Indenture
Trustee or Authentication Agent manually signs the certificate of authentication
on this Note.

          19.  Governing Law.  This Note and the Indenture shall be governed by
and construed in accordance with the laws of the State of New York, without
regard to principles of conflict of laws.

                              W I T N E S S E T H:
                              -------------------

     WHEREAS, this agreement is entered into in connection with the Indenture, 
dated as of October 28, 1997, between Transtel S.A., a Colombian corporation

"Notes");

     WHEREAS, under Section 4.15 of the Indenture, the Guarantor is not 
permitted to guarantee any indebtedness of the Borrower, unless, among other 
things, the Guarantor simultaneously executes and delivers a guarantee in the 
form of this Guarantee in favor of the Indenture Trustee for the benefit of the 
Holders (the "Secured Creditors"), under which the Guarantor (i) guarantees the 
due, full and punctual payment of the principal, premium, if any, and interest

Indenture Trustee or any Holder in enforcing any rights under this Guarantee

     WHEREAS, the Guarantor is a direct or indirect Subsidiary of the Borrower;

     WHEREAS, the Guarantor desires to execute this Guarantee in order to 
satisfy the conditions described in the preceding paragraphs;

<PAGE>
 
                                                                       EXHIBIT D
                                                                          Page 2

 
          NOW, THEREFORE, in consideration of the foregoing and other benefits 
accruing to the Guarantor, the receipt and sufficiency of which are hereby 
acknowledged, the Guarantor hereby makes the following representations and 
warranties to the Secured Creditors and hereby covenants and agrees with each 
Secured Creditor as follows:

          1.   The Guarantor irrevocably, absolutely and unconditionally
guarantees: to the Secured Creditors the full and prompt payment when due
(whether at the stated maturity, by acceleration or otherwise) of the Indenture
Obligations and all other obligations, liabilities and indebtedness owing by the
Borrower to the Secured Creditors under the Indenture (including, without
limitation, indemnities, fees and interest thereon), whether now existing or
hereafter incurred under, arising out of or in connection with the Indenture and
the due performance and compliance by the Borrower with all of the terms,
conditions and agreements contained in the Indenture (all such principal,
interest, liabilities, indebtedness and obligations being herein collectively
called the "Guaranteed Obligations"), whether now in existence or hereafter
arising. The Guarantor understands, agrees and confirms that the Secured
Creditors may enforce this Guarantee up to the full amount of the Guaranteed
Obligations against the Guarantor without proceeding against any other 
guarantor, the Borrower, against any security for the Guaranteed Obligations, or
under any other guaranty covering all or a portion of the Guaranteed
Obligations. This Guarantee shall constitute a guaranty of payment, and not of
collection.

          2.   The liability of the Guarantor hereunder is primary, absolute and
unconditional and is exclusive and independent of any security for or other
guaranty of the indebtedness of the Borrower or any Subsidiary thereof whether
executed by the Guarantor, any other guarantor or by any other party, and the
liability of the Guarantor hereunder shall not be affected or impaired by any
circumstance or occurrence whatsoever, including, without limitation: (a) any
direction as to application of payment by the Borrower or any Subsidiary thereof
or by any other party, (b) any other continuing or other guaranty, undertaking
or maximum liability of a guarantor or of any other party as to the Guaranteed
Obligations, (c) any payment on or in reduction of any such other guaranty or
undertaking, (d) any dissolution, termination or increase, decrease or change in
personnel by the Borrower or any Subsidiary thereof, (e) any payment made to any
Secured Creditor which such Secured Creditor repays the Borrower or any
Subsidiary thereof pursuant to court order in any bankruptcy, reorganization,
arrangement, moratorium or other debtor relief proceeding, and the Guarantor
waives any right to the deferral or modification of its obligations hereunder by
reason of any such proceeding, (f) any action or inaction by the Secured
Creditor as contemplated in Section 5 hereof or (g) any invalidity, irregularity
or unenforceability of all or any part of the Guaranteed Obligations or of any
security therefor.

          3.   The obligations of the Guarantor hereunder are independent of the
obligations of any other guarantor, the Borrower or any Subsidiary thereof, and 
a separate
<PAGE>
 
                                                                       EXHIBIT D
                                                                          Page 3


action or actions may be brought and prosecuted against the Guarantor whether or
not action is brought against any other guarantor, the Borrower or any 
Subsidiary thereof and whether or not any other guarantor, the Borrower or any 
Subsidiary thereof be joined in any such action or actions. The Guarantor
waives, to the fullest extent permitted by law, the benefits of any statute of
limitations affecting its liability hereunder or the enforcement thereof. Any
payment by the Borrower or any Subsidiary thereof or other circumstance which
operates to toll any statute of limitations as to the Borrower or any such
Subsidiary shall operate to toll the statute of limitations as to the Guarantor.

          4.   The Guarantor hereby waives notice of acceptance of this 
Guarantee and notice of any liability to which it may apply, and waives 
promptness, diligence, presentment demand of payment, protest, notice of 
dishonor or nonpayment of any such liabilities, suit or taking of other action 
by the Indenture Trustee or any other Secured Creditor against, and any other 
notice to, any party liable thereon (including the Guarantor, any other 
guarantor, the Borrower or any Subsidiary thereof).

          5.   Any Secured Creditor may at any time and from time to time 
without the consent of, or notice to, the Guarantor, without incurring 
responsibility to the Guarantor, without impairing or releasing the obligations 
of the Guarantor hereunder, upon or without any terms or conditions and in whole
or in part:

          (a)  exercise or refrain from exercising any rights against the
     Borrower, any guarantor (including the Guarantor), any Subsidiary thereof
     or otherwise act or refrain from acting;

          (b)  apply any sums by whomsoever paid or howsoever realized to any
     liability or liabilities of the Borrower or any Subsidiary thereof to the
     Secured Creditors regardless of what liabilities of the Borrower or such
     Subsidiary remain unpaid;

          (c)  consent to or waive any breach of, or any act, omission or
     default under, the Indenture or any of the instruments or agreements
     referred to therein;

          (d)  act or fail to act in any manner referred to in this Guarantee
     which may deprive the Guarantor of its right to subrogation against the
     Borrower or any Subsidiary thereof to recover full indemnity for any
     payments made pursuant to this Guarantee; and/or

          (e)  take any other action which would, under otherwise applicable
     principles of common law, give rise to a legal or equitable discharge of
     the Guarantor from its liabilities under this Guarantee.
<PAGE>
 
                                                                       EXHIBIT D
                                                                          Page 4


          6.   This Guarantee is a continuing one and all liabilities to which 
it applies or may apply under the terms hereof shall be conclusively presumed to
have been created in reliance hereon. No failure or delay on the part of any 
Secured Creditor in exercising any right, power or privilege hereunder shall 
operate as a waiver thereof, nor shall any single or partial exercise of any 
right, power or privilege hereunder preclude any other or further exercise 
thereof or the exercise of any other right, power or privilege. The rights and 
remedies herein expressly specified are cumulative and not exclusive of any 
rights or remedies which any Secured Creditor would otherwise have. No notice to
or demand on the Guarantor in any case shall entitle the Guarantor to any other 
further notice or demand in similar or other circumstances or constitute a 
waiver of the rights of any Secured Creditor to any other or further action in 
any circumstances without notice or demand. It is not necessary for any Secured 
Creditor to inquire into the capacity or powers of the Borrower or any 
Subsidiary thereof or the officers, directors, partners or agents acting or 
purporting to act on its behalf, and any indebtedness made or created in 
reliance upon the professed exercise of such powers shall be guaranteed 
hereunder. 

          7.   Any indebtedness of the Borrower or any Subsidiary thereof now or
hereafter held by the Guarantor is hereby subordinated to the indebtedness of 
the Borrower or such Subsidiary to the Secured Creditors, and such indebtedness 
of the Borrower or such Subsidiary to the Guarantor, if the Indenture Trustee, 
after the occurrence and during the continuance of an Event of Default, so 
requests, shall be collected, enforced and received by the Guarantor as trustee 
for the Secured Creditors and be paid over to the Secured Creditors on account 
of the indebtedness of the Borrower or such Subsidiary to the Secured Creditors,
but without affecting or impairing in any manner the liability of the Guarantor 
under the other provisions of this Guarantee. Without limiting the generally of 
the foregoing, the Guarantor hereby agrees with the Secured Creditors that it 
will not exercise any right of subrogation which it may at any time otherwise 
have as a result of this Guarantee until all Guaranteed Obligations have been 
irrevocably paid in full in cash.

          8. (a) The Guarantor waives any right (except as shall be required by 
applicable law and cannot be waived) to require the Secured Creditors to: (i)
proceed against the Borrower, any Subsidiary thereof, any other guarantor of the
Guaranteed Obligations or any other party; (ii) proceed against or exhaust any 
security held from the Borrower, any Subsidiary thereof, any other guarantor of 
the Guaranteed Obligations or any other party; or (iii) pursue any other remedy 
in the Secured Creditors' power whatsoever. The Guarantor waives any defense 
based on or arising out of any defense of the Borrower, any Subsidiary thereof, 
any other guarantor of the Guaranteed Obligations or any other party other than 
payment in full of the Guaranteed Obligations, including, without limitation, 
any defense based on or arising out of the disability of the Borrower, any 
Subsidiary thereof, any other guarantor of the Guaranteed Obligations or any 
other party, or the unenforceability of the Guaranteed Obligations or any part 
thereof from any cause,



 
<PAGE>
 
                                                                       EXHIBIT D
                                                                          Page 5

or the cessation from any cause of the liability of the Borrower or any 
Subsidiary thereof other than payment in full of the Guaranteed Obligations. The
Secured Creditors may, at their election, foreclose on any security held by the 
Indenture Trustee or the other Secured Creditors by one or more judicial or 
nonjudicial sales, whether or not every aspect of any such sale is commercially 
reasonable, or exercise any other right or remedy the Secured Creditors may have
against the Borrower or any Subsidiary thereof or any other party, or any
security, without affecting or impairing in any way the liability of the
Guarantor hereunder except to the extent the Guaranteed Obligations have been
paid in full. The Guarantor waives any defence arising out of any such election
by the Secured Creditors, even though such election operates to impair or
extinguish any right of reimbursement or subrogation or other right or remedy of
the Guarantor against the Borrower or any Subsidiary thereof or any other party
or any security.

          (b)  The Guarantor waives all presentments, demands for performance, 
protests and notices, including, without limitation, notices of nonperformance, 
notices of protest, notices of dishonor, notices of acceptance of this 
Guarantee, and notices of the existence, creation or incurring of new or 
additional indebtedness. The Guarantor assumes all responsibility for being and 
keeping itself informed of the Borrower's and each of its Subsidiary's financial
condition and assets, and of all other circumstances bearing upon the risk of 
nonpayment of the Guaranteed Obligations and the nature, scope and extent of the
risks which the Guarantor assumes and incurs hereunder, and agrees that the 
Secured Creditors shall have no duty to advise the Guarantor of information 
known to them regarding such circumstances or risks.

          9.   The Secured Creditors agree that this Guarantee may be enforced 
only by the action of the Indenture Trustee and that no other Secured Creditors 
shall have any right individually to seek to enforce or enforce this Guarantee.
The Secured Creditors further agree that this Guarantee may not be enforced 
against any director, officer, employee, partner or stockholder of the Guarantor
(except to the extent such partner or stockholder is also a Guarantor 
hereunder).

          10.  The Guarantor represents, warrants and covenants that:

          (a)  It (i) is a duly organized and validly existing corporation or
     partnership in good standing under the laws of the jurisdiction of its
     organization, (ii) has the corporate or partnership power and authority to
     own its property and assets and to transact the business in which it is
     engaged and presently proposes to engage and (iii) is duly qualified and is
     authorized to do business and is in good standing in each jurisdiction
     where the conduct of its business requires such qualification except for
     failures to be so qualified which, individually or in the aggregate, could
     not reasonably be expected to have a material adverse effect on the
     business, opera-

                                                                       EXHIBIT D
                                                                          Page 6

     tions property, assets, liabilities, conditions (financial or otherwise) or
     prospects of the Borrower or of the Borrower and its Subsidiaries taken as
     a whole.

          (b)  It has the corporate or partnership power and authority to
     execute, deliver and perform the terms and provisions of this Guarantee and
     has taken all necessary corporate or partnership actions to authorize the
     execution, delivery and performance by it of this Guarantee. The Guarantor
     has duly executed and delivered this Guarantee, and this Guarantee
     constitutes the legal, valid and binding obligation of the Guarantor
     enforceable in accordance with its terms, except to the extent that the
     enforceability hereof or thereof may be limited by applicable bankruptcy,
     insolvency, reorganization, moratorium or other similar laws generally
     affecting creditors' rights and by equitable principles (regardless of
     whether enforcement is sought in equity or at law).

          (c)  Neither the execution, delivery or performance by the Guarantor
     of this Guarantee, nor compliance by it with the terms and provisions
     hereof, will (i) contravene any provision of any applicable law, statute,
     rule or regulation or any applicable order, writ, injunction or decree of
     any court or governmental instrumentality, (ii) conflict with or result in
     any breach of any of the terms, covenants, conditions or provisions of, or
     constitute a default under, or result in the creation or imposition of (or
     the obligation to create or impose) any Lien upon any of the property or
     assets of the Guarantor or any of its Subsidiaries pursuant to the terms of
     any indenture, mortgage, deed of trust, loan agreement, credit agreement,
     or any other material agreement, contract or instrument to which the
     Guarantor or any of its Subsidiaries is a party or by which it or any of
     its property or assets is bound or to which it may be subject or (iii)
     violate any provision of the certificate of incorporation or by-laws (or
     equivalent organizational documents) of the Guarantor or any of its
     Subsidiaries.

          (d)  No order, consent, approval, license, authorization or validation
     of, or filing, recording or registration with (except as have been obtained
     or made), or exemption by, any governmental or public body or authority, or
     any subdivision thereof, is required to authorize, or is required for, (i)
     the execution, delivery and performance of this Guarantee by the Guarantor
     or (ii) the legality, validity, binding effect or enforceability of this
     Guarantee to which the Guarantor is a party.

          (e)  There are no actions, suits or proceedings pending or threatened
     (i) with respect to this Guarantee or (ii) with respect to the Guarantor
     that could reasonably be expected to materially and adversely affect (a)
     the business, operations, property, assets, liabilities, condition
     (financial or otherwise) or prospects of the Borrower or of the Borrower
     and its Subsidiaries taken as a whole or (b) the rights or remedies

     17. All notices, requests, demands or other communications pursuant hereto

and in such event the Guarantor agrees that any such judgment, decree, order,
settlement or compromise shall be binding upon thee Guarantor, notwithstanding
any revocation hereof or other instrument evidencing any liability of the
Borrower or any Subsidiary thereof, and the Guarantor shall be and remain liable
to the aforesaid payees hereunder for the amount so repaid or recovered to the
same extent as if such amount had never originally been received by any such
payee.

     19.  (a)  THIS GUARANTEE AND THE RIGHTS AND OBLIGATIONS OF THE SECURED 
CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK. Any legal action or proceeding

irrevocably waives any objection to such service of process and further 
irrevocably waives and agrees not to plead or claim in any action or proceeding 
commenced hereunder that such service of process was in any way invalid or 
ineffective. Nothing herein shall affect the right of any of the Secured 
Creditors to serve process in any other manner permitted by law or to commence 
legal proceedings or otherwise proceed against the Guarantor in any other 
jurisdiction.

          (b)  The Guarantor hereby irrevocably waives (to the fullest extent 
permitted by applicable law) 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 Guarantee brought in the courts referred to in

BENEFITS OF THIS GUARANTEE) HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL BY 
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO

Guarantor, terminate, and have no further force or effect (it being understood 
and agreed that the sale of one or more Persons that own, directly or 
indirectly, all of the capital stock or partnership interests of the Guarantor

21).

          21.  This Guarantee may be executed in any number of counterparts and 
by the different parties hereto on separate counteparts, each of which when so

Marine Midland Bank,
 as Indenture Trustee (as defined below)
140 Broadway, 12th Floor
New York, New York  10005

Siemens A.G.
[Address]

Germany


Ladies & Gentlemen:

     This letter confirms the agreements made by the undersigned, Global
Telecommunications Operations, Inc., a British Virgin Islands company
("Global"), in connection with the offering by Transtel S.A., a Colombian
corporation ("Transtel"), of 12 1/2% Senior Notes due 2007 (the "Senior Notes"),
as described in the Offering Memorandum, dated October 21, 1997 (the "Offering
Memorandum").  Global is owned by the same shareholders who own Transtel (the
"Shareholders").  The Senior Notes will be issued under the Indenture, dated as
of October 28, 1997, between Transtel and Marine Midland Bank, as indenture
trustee for the benefit of the holders of the Senior Notes (the "Indenture
Trustee").


BACKGROUND

     Global was formed by the Shareholders in January 1995 for the exclusive
purpose of acting as a financing vehicle for the purchase of telecommunications
equipment from Siemens A.G. ("Siemens") to be used by the subsidiaries of
Transtel (the "Operating Subsidiaries") for the

                                      E-1

development of their telephone networks.  Generally, Siemens finances its sale
of equipment to Global (the "Siemens Financing"), and then Global on-leases such
equipment to an Operating Subsidiary pursuant to a lease agreement (each, a
"Lease") with terms substantially similar to the Siemens Financing.

     As part of the Expansion Plan (as defined and described in the Offering
Memorandum), Global has entered into the purchase agreements described in
Exhibit A hereto and has signed the letters of intent described in Exhibit A
hereto which is intended to result in one or more additional purchase agreement
(such purchase agreements and the letters of intent, are referred to herein as
the "Purchase Agreements").  For purposes of this letter agreement, all
telecommunications equipment purchased by Global from Siemens prior to and after
the date hereof under any of the Purchase Agreements, and all replacements and
upgrades of such equipment, is referred to herein as the "Equipment".

     In consideration for Siemens agreeing to modify certain terms to the
existing Purchase Agreements, the Company has agreed to guaranty Global's
obligations under the Siemens Financing.  In addition, Global has agreed to
assign to Siemens the lease payments under each of the Leases in the event of an
event of default under the Purchase Agreements.

     It is a condition to the issuing of the Senior Notes under the Indenture
that Global shall have executed and delivered this letter agreement.  Global
will obtain benefits from the issuance of the Senior Notes by Transtel and
desires to execute this letter agreement in order to satisfy the condition
described in the preceding sentence.


AGREEMENTS

     Subject to the terms of this letter agreement, for so long as the Senior
Notes are outstanding, Global hereby agrees to the following:

     1.   Not to, directly or indirectly, engage in any business other than the
business of purchasing telecommunications equipment and the leasing of such
telecommunications equipment to Transtel or an Operating Subsidiary.

     2.   Not to incur any indebtedness ("Global Indebtedness"), unless Transtel
and the Operating Subsidiaries are in compliance with Section 4.08 of the
Indenture after giving effect to any lease or guaranty arrangements entered into
by Transtel or any Operating Subsidiary which constitute the incurrence of
Indebtedness (as defined in the Indenture) under the Indenture in connection
with such Global Indebtedness and such Global Indebtedness is used for the
purchase of telecommunications equipment to be leased to an Operating
Subsidiary.

     3.   To the extent it sells or otherwise disposes of any of the Equipment,
it agrees to apply all cash proceeds received by it in respect of any sale of,
collection from, or other realization upon any Equipment to prepay on a pro rata
basis the Senior Notes and any amounts owing by Global to Siemens under any
purchase agreement for Equipment.

Ladies and Gentlemen:

          In connection with our proposed purchase of $_______________ aggregate
principal amount of the Notes, we confirm that:

          1.   We understand that any subsequent transfer of the Notes is
     subject to certain restrictions and conditions set forth in the Indenture
     dated as of October 28, 1997 relating to the Notes (the "Indenture") and
     the undersigned agrees to be bound by, and not to resell, pledge or

     and conditions and the Securities Act of 1933, as amended (the "Securities
     Act").

          2.   We understand that the Notes have not been registered under the
     Securities Act, and that the Notes may not be offered or sold except as
     permitted in the following sentence.  We agree, on our own behalf and on
     behalf of any accounts for which we are acting as hereinafter stated, that
     if we should sell any Notes within two years after the original issuance of
     the Notes, we will do so only (A) to the Company or any subsidiary thereof,

     bear a legend to the foregoing effect.

          4.   We are an institutional "accredited investor" (as defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
     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

     for one or more accounts (each of which is an institutional "accredited
     investor") as to each of which we exercise sole investment discretion.

to rely upon this letter and are irrevocably authorized to produce this letter
or a copy hereof to any interested party in any administrative or legal
proceedings or official inquiry with respect to the matters covered hereby.

          Except as set forth in the Exchange Certificate Guarantee, the
Certificates do not represent a direct obligation of, or an obligation
guaranteed by, or an interest in, the Company or the Pass Through Trustee or any
affiliate thereof.  The Certificates are limited in right of payment, all as
more specifically set forth in the Agreement.  All payments or distributions
made to Certificateholders under the Agreement shall be made only from the Trust
Property and only to the extent that the Paying Agent shall have sufficient
income or proceeds from the Trust Property to make such payments in accordance
with the terms of the Agreement.  Each Holder of this Certificate, by its
acceptance hereof, agrees that it will look solely to the income and proceeds
from the Trust Property to the extent available for distribution to such Holder
as provided in the Agreement.  This Certificate does not purport to summarize
the Agreement and reference is made to the Agreement for information with
respect to the interests, rights, benefits, obligations, proceeds, and duties
evidenced hereby.  A copy of the Agreement may be examined during normal
business hours at the principal office of the Pass Through Trustee, and at such
other places, if any, designated by the Pass Through Trustee, by any
Certificateholder upon request.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Certificateholders under the Agreement at any time
by the Company and the Pass Through Trustee with the consent of the Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
a majority in interest in the Trust.  Any such consent by the Holder of this
Certificate shall be conclusive and binding on such Holder and upon all future
Holders of this Certificate and of any Certificate issued upon the transfer
hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate.  The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Registrar, or by any successor Registrar,
duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Registrar, duly executed by the Holder hereof or such
Holder's attorney, duly authorized in writing, and thereupon one or more new
Certificates of authorized denominations evidencing the same aggregate
Fractional Undivided Interest in the Trust will be issued to the designated
transferee or transferees.

          The Certificates are issuable only as registered Certificates without
coupons initially in minimum denominations of $250,000 Fractional Undivided
Interest and any integral multiples of $1,000 in excess thereof.  At such time
as certain restrictions on transfer have been removed, the minimum denominations
of the Certificates shall be reduced to $1,000 or any integral multiples of
$1,000 in excess thereof.  As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of authorized denominations 
<PAGE>
 
evidencing the same aggregate Fractional Undivided Interest in the Trust, as
requested by the Holder surrendering the same.

          No service charge will be made for any such registration of transfer
or exchange, but the Pass Through Trustee shall require payment of a sum
sufficient to cover any tax or governmental charge payable in connection
therewith.

          The Pass Through Trustee, the Registrar, and any agent of the Pass
Through Trustee or the Registrar may treat the person in whose name this
Certificate is registered as the owner hereof for all purposes, and neither the
Pass Through Trustee, the Registrar, nor any such agent shall be affected by any
notice to the contrary.

  The obligations and responsibilities created by the Agreement and the Trust
created thereby shall terminate upon the distribution to Certificateholders of
all amounts required to be distributed to them pursuant to the Agreement and the
disposition of all property held as part of the Trust Property.

may certify or give an opinion with respect to some matters and one or more

                                       9
<PAGE>
 
other such Persons as to other matters and any such Person may certify or give
an opinion as to such matters in one or several documents.

          Any Opinion of Counsel stated to be based on the opinion of other
counsel shall be accompanied by a copy of such other opinion.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Trust Agreement, they may, but need not, be consolidated
and form one instrument.

          Section 1.04.  Acts of Holders.  (a) Any direction, consent, waiver or
                         ---------------
other action provided by this Trust Agreement 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 an agent 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 Pass
Through Trustee and, where it is hereby expressly required, to the Company or
the Indenture Trustee. 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 Trust Agreement and (subject to Section 8.01) conclusive
in favor of the Pass Through Trustee, and the Indenture Trustee, 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 certificate of any notary public or
other officer of any jurisdiction authorized to take acknowledgements of deeds
or administer oaths that the Person executing such instrument acknowledged to
him the execution thereof, or by an affidavit of a witness to such execution
sworn to before any such notary or such other officer and where such execution
is by an officer of a corporation or association or a member of a partnership,
on behalf of such corporation, association or partnership, such certificate or
affidavit shall also constitute sufficient proof of his 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 reasonable manner
which the Pass Through Trustee deems sufficient.

          (c)  In determining whether the Holders of the requisite Fractional
Undivided Interests of Certificates Outstanding have given any direction,
consent or waiver (a "Direction"), under this Trust Agreement, Certificates
owned by the Company or any Affiliate of the Company shall be disregarded and
deemed not to be Outstanding under this Trust Agreement for purposes of any such
determination. In determining whether the Pass Through Trustee shall be
protected in relying upon any such Direction, only Certificates which the Pass
Through Trustee knows to be so owned shall be so disregarded. Notwithstanding
the foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded as aforesaid, and (ii) if any
amount of Certificates so owned by any such Person have been pledged in good
faith, such Certificates shall not be disregarded as aforesaid if the pledgee
establishes to the satisfaction of the Pass Through Trustee the pledgee's right
so to act with respect to such Certificates and that the pledgee is not the
Company or any Affiliate of the Company.

                                       10
<PAGE>
 
          (d)  Any direction, consent, waiver or other action by the Holder of
any Certificate shall bind the Holder of every Certificate issued upon the
transfer thereof or in exchange therefor or in lieu thereof, whether or not
notation of such action is made upon such Certificate.

          (e)  Except as otherwise provided in Section 1.04(c), Certificates
owned by or pledged to any Person shall have an equal and proportionate benefit
under the provisions of this Trust Agreement, without preference, priority, or
distinction as among all of the Certificates.

Pass Through Trustee shall be valid and binding obligations of the Pass Through
Trustee, notwithstanding that such individual has ceased to be so authorized
prior to the authentication and delivery of such Certificates or did not hold
such office at the date of such Certificates.  No Certificate shall be entitled
to any benefit under this Trust Agreement, or be valid for any purposes, unless
there appears on such Certificate a certificate of authentication substantially
in the form set forth on Exhibit B hereto.

exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Pass Through Trustee, at the request of the
Registrar, shall execute, authenticate and deliver the Certificates that the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for registration of transfer or exchange shall be duly
endorsed or accompanied by a written instrument of transfer in the form of

Global Certificate, agree that transfers of beneficial interests in such Global

Holder of such Global Certificate (or its agent), and that ownership of a
beneficial interest in the Certificate shall be required to be reflected in a
book entry. When Certificates are presented to the Registrar or a co-Registrar
with a request to register the transfer or to exchange them for an equal
principal amount of Certificates of other authorized denominations, the
Registrar shall register the transfer or make the exchange as requested if its
requirements for such transactions are met. To permit registrations of transfers
and exchanges, the Pass Through Trustee shall execute and authenticate
Certificates at the Registrar's request. No service charge shall be made for any
registration of transfer or exchange of the Certificates, but the Company and
the Registrar may require payment of a sum sufficient to cover any transfer tax
or similar governmental charge payable in connection therewith.

exchange shall be cancelled and subsequently destroyed by the Registrar.

receives evidence to its satisfaction of the destruction, loss or theft of any
Certificate and (b) there is delivered to the Registrar and the Pass Through
Trustee such security, indemnity or bond, as may be required by them to save
each of them harmless, then, in the absence of notice to the Registrar or the
Pass Through Trustee that such Certificate has been acquired by a bona fide
purchaser, the Pass Through Trustee, at the request of the Registrar, shall
execute, authenticate and deliver, in 

                                       15

Certificate under this Section 4.05, the Pass Through Trustee and the Registrar
shall 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 Pass Through Trustee and the
Registrar) connected therewith. Any duplicate Certificate issued pursuant to
this Section 4.05 shall constitute conclusive evidence of the appropriate
Fractional Undivided Interest in the Trust, as if originally issued, whether or
not the lost, stolen or destroyed Certificate shall be found at any time.

permitted by this Trust Agreement. All cancelled Certificates held by the
Registrar shall be destroyed and a certification of their destruction delivered
to the Pass Through Trustee.

          Section 4.08.  Limitation of Liability for Payments.  All payments or

made only from the Trust Property and only to the extent that the Paying Agent
shall have sufficient income or proceeds from the Trust Property to make such
payments in accordance with the terms of Article V of this Trust Agreement. Each
Holder of a Certificate, by its acceptance of such Certificate, agrees that it
will look solely to the income and proceeds from the Trust Property to the
extent available for distribution to the Holder thereof as provided in this
Trust Agreement. Nothing in this Trust Agreement shall be construed as an

Physical Certificates of like tenor and amount.

          (e)  In connection with the transfer of an entire Global Certificate

                         -------------
may use "CUSIP" and "CINS" numbers (if then generally in use), and the Pass
Through Trustee and the Registrar shall use CUSIP numbers or CINS numbers, as
the case may be, in notices of exchange as a convenience to Holders; provided
                                                                     -------- 
that any such notice shall state that no representation is made as to the
correctness of such numbers either as printed on the Certificates or as
contained in any notice of exchange and that reliance may be placed only on the
other identification numbers printed on the Certificates.

                         -------------------
with the Registration Rights Agreement, each of the Company and the Trust have
agreed to file a registration statement for the issuance of registered
certificates with substantially identical terms to the Certificates, except that
the registered certificates will not contain terms with respect to transfer
restrictions. The interest rate payable on the Senior Notes shall be increased
by an amount equal to .50% per annum at the times specified in the Registration
Rights Agreement if either the Company or the Trust fails to satisfy certain
provisions of such Registration Rights Agreement to allow the Certificates to be
freely transferable by Certificateholders under the Securities Act.

          (b)  On each Special Distribution Date with respect to any Special
Payment or as soon thereafter as the Paying Agent has confirmed receipt of the
Special Payments due on the Senior Notes or realized upon the sale of any Senior
Note, the Pass Through Trustee shall cause the Paying Agent to distribute out of
the Special Payments Account, net of any applicable withholdings or deductions
for taxes, the amount deposited therein pursuant to Section 5.01(b) of such
Special Payment. There shall be so distributed to each Certificateholder of
record on the Record Date with respect to such Special Distribution Date (other
than as provided in Section 12.01 concerning the final distribution) by (i)
check mailed to such Certificateholder at the address appearing in the Register
or (ii) upon application to the Paying Agent, by wire transfer in immediately
available funds to an account maintained by the Certificateholder with a bank,

          (c)  The Pass Through Trustee shall cause the Paying Agent, at the
expense of the Company, to give notice of each Special Payment to each
Certificateholder at his address as it appears in the Register. In the event of
prepayment of Senior Notes, such notice shall be mailed not less than 20 days
prior to the date any such Special Payment is scheduled to be distributed. In
the case of any other Special Payments, such notice shall be mailed as soon as
practicable after the Paying Agent has confirmed that it has received funds for
such Special Payment. Notices mailed by the Paying Agent shall set forth:

               (i)  the Special Distribution Date and the Record Date therefor
          (except as otherwise provided in Section 12.01);

          amount Certificate and the amount thereof constituting principal,
          premium, if any, and interest;

             (iii)  the reason for the Special Payment; and

          Distribution Date, the total amount to be received on such date for
          each $1,000 face amount Certificate.

          If the amount of premium payable upon the redemption of a Senior Note
has not been calculated at the time that the Paying Agent mails notice of a
Special Payment, it shall be sufficient if the notice sets forth the other
amounts to be distributed and states that any premium received will also be
distributed.

          If any redemption of the Senior Notes held in the Trust is cancelled,
the Pass Through Trustee shall cause the Paying Agent, as soon as possible after
learning thereof, to mail notice thereof to each Certificateholder at its
address as it appears on the Register.

          (d)  Any amounts paid to the Certificateholders as a result of the
exercise of the rights under the Guarantee shall be in full satisfaction of the
corresponding obligation to make payment under the Certificates.

Distribution Date and Special Distribution Date, if any, included with each
distribution to Certificateholders will be a statement prepared by the Paying

                         --------------------------

          Section 5.05.  Additional Amounts.  (a) Except as provided in Section
                         ------------------
5.05(b) hereof and subject to the Company having provided the Trust with the
necessary funds, if the Trust is required to withhold or deduct or if the Trust
is otherwise required to pay any amount for or on account of Taxes imposed by a
Taxing Authority, from or in respect of any payment made under Section 5.02 of
this Trust Agreement, the Trust will pay, together with the payment under
Section 5.02, such additional amounts ("Additional Amounts") as may be necessary
so that the net amount received by each Certificateholder (including Additional
Amounts) after such withholding or deduction or other payment of Taxes will not
be less than the amount the Certificateholder would have received if such Taxes
had not been withheld or deducted or paid.

          (b)  No Additional Amounts will be payable with respect to a payment
made to a Certificateholder in any of the following circumstances:

                 (i)  With respect to any Tax which would not have been imposed,
          payable or due

                         (A) but for the existence of any present or former
                 connection between the Certificateholder (or the beneficial
                 owner of, or person having a right to acquire an interest in,
                 such Certificate) and a Taxing Authority, other than the mere
                 holding of the Certificates;

                                       23
<PAGE>
 
                         (B) if the Certificates are held in definitive
                 registered form and the presentation of the definitive
                 Certificate for payment had occurred within 30 days after the
                 date such payment was due and payable or was provided for,
                 whichever is later; or
      
                         (C) but for the failure of a Non-U.S. Certificateholder
                 to comply with certification, information or other reporting
                 requirements concerning the nationality, residence, identity or
                 business activity within the United States of such
                 Certificateholder (or, if applicable, the beneficial owner of,
                 or other person having a right to acquire an interest in, the
                 Certificate) if such compliance is a condition to such Taxes
                 not being imposed, payable or due with respect to the payment;
                 or

                (ii)  If, had the beneficial owner of, or other person having a
          right to acquire an interest in, such Certificate been the
          Certificateholder, such person would not have been entitled to the
          payment of Additional Amounts.

          (c)  Except as provided in the Section 13.01(b) hereof, in no event
will Additional Amounts be payable with respect to any tax that is payable
otherwise than by withholding from payments under Section 5.02 hereof.

          Section 5.06.  Stamp, Issue and Certain Other Taxes.  The Trust will
                         ------------------------------------
pay any stamp, issue, transfer, sales, use, value-added, property, registration,
documentary, enforcement or other similar taxes and other duties (including
interest and penalties) payable to any Taxing Authority in respect of the
creation, issue or offering of the Certificates or any other documents directly
related to such creation, issue or offering.

                         ----------------------------------
its own cost and expense, will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence, rights and

- --------  -------                                           
or franchise if it shall determine that the preservation thereof is no longer
desirable in the conduct of its business and that the loss thereof is not
prejudicial in any material respect to the Certificateholders.

          Section 6.02.  Consolidation, Merger or Sale of Assets Permitted.

punctual performance and observance of all of the covenants and conditions of
this Trust Agreement to be performed by the Company by supplemental agreement
given by such successor corporation to the Pass Through Trustee.

                         -------------------------------------------------- 
Company. Until such time as the Certificates have been registered for resale by
- -------               
the Certificateholders pursuant to the Securities Act by the Company, the
Company will furnish to any Certificateholder upon request, copies of the

                         -----------------------------------------------
Certificates. Until such time as the Certificates have been registered for

the Company shall not acquire any beneficial interest, and will cause its
"affiliates" (as defined in paragraph (a)(l) of Rule 144 under the Securities
Act) not to acquire any beneficial interest, in any Certificate unless they
notify the Pass Through Trustee and Registrar of such acquisition. The Pass
Through Trustee, the Registrar and all Certificateholders shall be entitled to
rely without further investigation on any such notification (or the lack
thereof).

                                  ARTICLE VII

                                    DEFAULT

          Section 7.01.  Events of Default. If any Indenture Event of Default
                         -----------------
(an "Event of Default") shall occur and be continuing, then, and in each and
every case, so long as such Indenture Event of Default shall be continuing, and
upon the direction of the Certificateholders evidencing Fractional Undivided
Interests aggregating not less than 25% interest in the Trust, the Pass Through
Trustee shall vote a corresponding 25% of such Senior Notes, in favor of
directing the Indenture Trustee, to declare the unpaid principal amount of the
Senior Notes then outstanding and accrued interest thereon to be due and payable
under, and in accordance with the provisions of, the Indenture. In addition, if
an Indenture Event of Default shall have occurred and be continuing, and upon
the direction of the Certificateholders evidencing Fractional Undivided Interest
aggregating not less than a majority in interest of the Trust, the Pass Through
Trustee shall vote a corresponding majority of such Senior Notes to direct the
Indenture Trustee regarding the exercise of remedies provided in Article VI of
the Indenture.

          At any time after a declaration of acceleration with respect to the
Senior Notes as described in the preceding paragraph, but before a judgment or
decree for the payment of money due has been obtained by the Indenture Trustee,
the Certificateholders evidencing at least a majority in interest in the Trust
may rescind and cancel such declaration and its consequences (i) if the
recission would not conflict with any judgment or decree, (ii) if all existing
Indenture Events of Default have been cured or waived except nonpayment of
principal or interest that has become due solely because of the acceleration,
(iii) to the extent the payment of such interest is lawful, interest on overdue
installments of interest and overdue principal, which has become due otherwise
than by such declaration of acceleration, has been paid, (iv) if the Company has
paid the Indenture Trustee its reasonable compensation and reimbursed the
Indenture Trustee for its expenses, disbursements and advances and (v) in the
event of the cure or waiver of an Indenture Event of Default specified in clause
(h) of Section 6.01 of the Indenture, the Indenture Trustee shall have received
an Officer's Certificate and an Opinion of Counsel that such Event of Default
has been cured or waived.

          In addition, after an Event of Default shall have occurred and be
continuing, the Pass Through Trustee, upon the direction of the
Certificateholders evidencing Fractional Undivided Interests aggregating not
less than a majority in interest in the Trust shall, by such officer or agent as
it may appoint, subject to complying with the terms of the Indenture and the
Senior Notes, sell, convey, transfer and deliver such Senior Note or Senior
Notes, without recourse to or warranty by the Pass Through Trustee or any
Certificateholder, to any Person.  In any such case, the Pass Through Trustee
shall, on behalf of the Trust, sell, assign, contract to sell or otherwise
dispose of and deliver such Senior Note or Senior Notes in one or more parcels
at public or private sale or sales, at any location or locations selected by the
Certificateholders, all upon such terms and conditions, and at such prices, for
cash as it shall be directed by the Certificateholders.  If the Pass Through
Trustee so decides or is required to sell or otherwise dispose of any Senior
Note pursuant to this Section, the Pass Through Trustee shall take such of the
actions described above, as it shall be directed by the Certificateholders, as
it may reasonably deem most effectual to complete the sale or other disposition
of such Senior Note, so as to provide for the payment in full of all amounts due
on the Certificates.  The Pass Through Trustee shall give notice to the Company
promptly after any such sale.

          Section 7.02. Incidents of Sale of Senior Notes. Upon any sale of all
                        ---------------------------------
or any part of the Senior Notes made either under the power of sale given under
this Trust Agreement or otherwise for the enforcement of this Trust Agreement,
the following shall be applicable:

          (1)  Certificateholders and Pass Through Trustee May Purchase Senior
               ---------------------------------------------------------------
     Notes. Any Certificateholder, the Pass Through Trustee in its individual or
     -----
     any other capacity or any other Person may bid for and purchase any of the
     Senior Notes, and upon compliance with the terms of sale, may hold, retain,
     possess and dispose of such Senior Notes in their or its or his own
     absolute right without further accountability.

     (2)  Receipt of Pass Through Trustee Shall Discharge Purchaser. The
          ---------------------------------------------------------  
     receipt of the Pass Through Trustee or the Paying Agent or of the officer
     making such sale shall be a sufficient discharge to any purchaser for his
     purchase money, and, after paying such purchase money and receiving such
     receipt, such purchaser or his personal representative or assigns shall not
     be obliged to see to the application of such purchase money, or be in any
     way answerable for any loss, misapplication or nonapplication thereof.

     (3)  Application of Moneys Received upon Sale. Any moneys collected by the
          ----------------------------------------                              
     Paying Agent at the direction of the Pass Through Trustee upon any sale
     made either under the power of sale given by this Trust Agreement or
     otherwise for the enforcement of this Trust Agreement, shall be applied as
     provided in Section 5.02.

          Section 7.03. Judicial Proceedings Instituted by Pass Through Trustee.
                        -------------------------------------------------------
(a)  Pass Through Trustee May Bring Suit.  If there shall be a failure to make
     -----------------------------------                                 
payment of the principal of, premium, if any, or interest on any Senior Note,
then the Pass Through Trustee, in its own name, and as trustee of an express
trust, as holder of such Senior Notes, shall be, to the extent permitted by and
in accordance with the terms of the Note Documents, entitled and empowered to
(but shall be under no affirmative obligation) to institute any suits, actions
or proceedings at law, in equity or otherwise, for the collection of the sums so
due and unpaid on such Senior Notes and

                                       26
<PAGE>
 
may prosecute any such claim or proceeding to judgment or final decree with
respect to the whole amount of any such sums so due and unpaid.

          (b)  Pass Through Trustee May File Proofs of Claim; Appointment of
               -------------------------------------------------------------
Pass Through Trustee as Attorney-in-Fact in Judicial Proceedings.  Upon demand
- ----------------------------------------------------------------
by the Company, the Pass Through Trustee in its own name, or as trustee of an
express trust, or as attorney-in-fact for the Certificateholders, or in any one
or more of such capacities (irrespective of whether distributions on the
Certificates shall then be due and payable, or the payment of the principal on
the Senior Notes shall then be due and payable, as therein expressed or by
declaration or otherwise and irrespective of whether the Pass Through Trustee
shall have made any demand to the Indenture Trustee for the payment of overdue
principal, premium (if any) or interest on the Senior Notes), shall be entitled
and empowered to (but shall be under no affirmative obligation) to file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Pass Through Trustee and of the
Certificateholders allowed in any receivership, insolvency, bankruptcy,
liquidation, readjustment, reorganization or any other judicial proceedings
relative to the Company, their respective creditors or property. Any receiver,
assignee, trustee, liquidator sequestrator (or similar official) in any such
judicial proceeding is hereby authorized by each Certificateholder to make
payments in respect of such claim to the Pass Through Trustee, and in the event
that the Pass Through Trustee shall consent to the making of such payments
directly to the Certificateholders, to pay to the Pass Through Trustee any
amount due to it for the reasonable compensation, expenses, disbursements,
indemnity and advances of the Pass Through Trustee, its agents and counsel.
Nothing contained in this Trust Agreement shall be deemed to give to the Pass
Through Trustee any right to accept or consent to any plan of reorganization or
otherwise by action of any character in any such proceeding to waive or change
in any way any right of any Certificateholder.

          Section 7.04.  Control by Certificateholders. The Certificateholders
                         -----------------------------
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest in the Trust shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Pass Through
Trustee, or exercising any trust or power conferred on the Pass Through Trustee
under this Trust Agreement, including any right of the Pass Through Trustee as
holder of the Senior Notes, provided that
                            --------     

          (1)  such direction shall not be in conflict with any rule of law or
     with this Trust Agreement and would not involve the Pass Through Trustee in
     personal liability or expense,

          (2)  the Pass Through Trustee shall not determine that the action so
     directed would be unjustly prejudicial to the Certificateholders not taking
     part in such direction,

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

          (4)  if an Indenture Event of Default shall have occurred and be
     continuing, such direction shall not obligate the Pass Through Trustee to
     vote more than a corresponding majority, of the related Senior Notes held
     by the Trust in favor of directing any action by the Indenture Trustee with
     respect to such Indenture Event of Default, and

                                       27
<PAGE>
 
          (5)  in the case of the Pass Through Trustee exercising any right as
     holder of the Senior Notes, if the Indenture provides that such right can
     only be exercised upon a vote of the Senior Noteholders aggregating greater
     than a majority of the principal amount outstanding of such Notes (a
     "Required Percentage"), then the Pass Through Trustee may only exercise
     such right upon a direction of the Certificateholders evidencing a
     Fractional Undivided Interest aggregating a percentage of the Certificates
     Outstanding equal to such Required Percentage.

          Section 7.05.  Waiver of Defaults. The Certificateholders evidencing
                         ------------------
Fractional Undivided Interests aggregating not less than a majority in interest
in the Trust may on behalf of the Certificateholders of all the Certificates
waive any existing Default or Event of Default hereunder and its consequences or
may instruct the Pass Through Trustee to waive any default pursuant to Section
6.04 of the Indenture and its consequences, except a Default:

          (1)  in the deposit of any Scheduled Payment or Special Payment under
     Section 5.01 or in the distribution of any payment under Section 4.02 on
     the Certificates, or

          (2)  in the payment of the principal of, premium, if any, or interest
     on any Senior Notes, or

          (3)  in respect of a covenant or provision hereof which under Article
     X hereof cannot be modified or amended without the consent of the
     Certificateholder of each Outstanding Certificate affected.

          Upon any such waiver, such Default shall cease to exist with respect
to this Trust Agreement, and any Event of Default arising therefrom shall be
deemed to have been cured for every purpose of this Trust Agreement and any
direction given by the Pass Through Trustee on behalf of such Holders to the
Indenture Trustee shall be annulled with respect thereto; but no such waiver
shall extend to any subsequent or other Default or Event of Default or impair
any right consequent thereon.  Upon any such waiver, the Pass Through Trustee
shall vote the Senior Notes issued under the Indenture to waive the
corresponding Indenture Default or Indenture Event of Default.

          Section 7.06.  Undertaking to Pay Court Costs. All parties to this
                         ------------------------------
Trust Agreement, and each Certificateholder by his acceptance of a Certificate,
shall be deemed to have agreed that any court may in its discretion require, in
any suit, action or proceeding for the enforcement of any right or remedy under
this Trust Agreement, or in any suit, action or proceeding against the Pass
Through Trustee for any action taken or omitted by it as Pass Through Trustee
hereunder, the filing by any party litigant in such suit, action or proceeding
of an undertaking to pay the costs of such suit, action or proceeding, and that
such court may, in its discretion, assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, action or proceeding,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; provided, however, that the provisions of this Section 
                     --------  -------                          
shall not apply to (a) any suit, action or proceeding instituted by any
Certificateholder or group of Certificateholders evidencing Fractional Undivided
Interests aggregating more than 10% of the Trust, (b) any suit, action or
proceeding instituted by any Certificateholder for the enforcement

                                       28
<PAGE>
 
of the distribution of payments pursuant to Section 5.02 hereof on or after the
respective due dates expressed herein or (c) any suit, action or proceeding
instituted by the Pass Through Trustee.

          Section 7.07.  Right of Certificateholders to Receive Payments Not to
                         ------------------------------------------------------
Be Impaired. Anything in this Trust Agreement to the contrary notwithstanding,
- -----------
including without limitation Section 7.08 hereof, the right of any
Certificateholder to receive distributions of payments required pursuant to
Section 5.02 hereof on the Certificates when due, or to institute suit for the
enforcement of any such payment on or after the applicable Distribution Date or
Special Distribution Date, shall not be impaired or affected without the consent
of such Certificateholder.

          Section 7.08.  Certificateholders May Not Bring Suit Except Under
                         --------------------------------------------------
Certain Conditions. A Certificateholder shall not have the right to institute
- ------------------
any suit, action or proceeding at law or in equity or otherwise with respect to
this Trust Agreement, for the appointment of a receiver or for the enforcement
of any other remedy under this Trust Agreement, unless:

          (1)  such Certificateholder previously shall have given written notice
     to the Pass Through Trustee of a continuing Event of Default;

          (2)  the Certificateholders evidencing Fractional Undivided Interests
     aggregating not less than a majority in interest of the Trust shall have
     requested the Pass Through Trustee in writing to institute such action,
     suit or proceeding and shall have offered to the Pass Through Trustee
     indemnity as provided in Section 8.03(e);

          (3)  the Pass Through Trustee shall have refused or neglected to
     institute any such action, suit or proceeding for 60 days after receipt of
     such notice, request and offer of indemnity; and

          (4)  no direction inconsistent with such written request has been
     given to the Pass Through Trustee during such 60-day period by the
     Certificateholders evidencing Fractional Undivided Interests aggregating
     not less than a majority in interest in the Trust.

          It is understood and intended that no one or more of the
Certificateholders shall have any right in any manner whatsoever hereunder or
under the Certificates to (i) surrender, impair, waive, affect, disturb or
prejudice any Trust Property, or the rights of the Certificateholders or the
holders of the Senior Notes, (ii) obtain or seek to obtain priority over or
preference to any other such Holder or (iii) enforce any right under this Trust
Agreement, except in the manner herein provided and for the equal, ratable and
common benefit of all the Certificateholders subject to the provisions of this
Trust Agreement.

                         -------------------
the Pass Through Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                           THE PASS THROUGH TRUSTEE

          Section 8.01.  Certain Duties and Responsibilities. (a)  The Pass
                         -----------------------------------
Through Trustee is authorized and directed to execute and deliver the Trust
Documents on behalf of the Trust and each certificate or other document attached
as an exhibit to or contemplated by the Trust Documents and any amendment
thereto, in each case, in such form as the Depositor shall approve as evidenced
conclusively by the Pass Through Trustee's execution thereof. In addition to the
foregoing, the Pass Through Trustee is authorized, but shall not be obligated,
to take all actions required of the Trust pursuant to the Trust Documents. The
Pass Through Trustee is further authorized from time to time to take such action
as the Depositor or the Certificateholders recommend or direct in writing
pursuant to this Trust Agreement and the Trust Documents.

          (b)  The Pass Through Trustee undertakes to perform such duties and
only such duties as are set forth in this Trust Agreement, and no implied
covenants or obligations shall be read into this Trust Agreement against the
Pass Through Trustee.

          (c)  It shall be the duty of the Pass Through Trustee to discharge (or
cause to be discharged) all of its responsibilities pursuant to the terms of
this Trust Agreement and to administer the Trust in the interest of the
Certificateholders in accordance with the provisions of this Trust Agreement.
Notwithstanding the foregoing, the Pass Through Trustee shall be deemed to have
discharged its duties and responsibilities hereunder to the extent the
Depositor, the Paying Agent or the Registrar agrees to perform any act or to
discharge any duty of the Pass Through Trustee or the Trust hereunder or under
any Trust Document, and the Pass Through Trustee shall not be liable for the
default or failure of the Depositor, the Paying Agent or the Registrar to carry
out its obligations under this Trust Agreement or any Trust Document.

          (d)  Notwithstanding the foregoing, the Pass Through Trustee shall not
be required to take any action hereunder or under any Trust Document if the Pass
Through Trustee shall reasonably determine, or shall have been advised by
counsel in writing, that such action is likely to result in personal liability

Through Trustee that such action will result in such consequences, the Pass
Through Trustee will appoint an additional trustee pursuant to Section 8.10
hereof to proceed with such action; and

negligent action, its own grossly negligent failure to act, or its own willful
misconduct, except that

          (1)  this Subsection shall not be construed to limit the effect of

     to notices of Default or handling of funds hereunder or grossly negligent
     in ascertaining the pertinent facts;

     remedy available to the Pass Through Trustee, or exercising any trust or
     power conferred upon the Pass Through Trustee, under this Trust Agreement;
     and

     Through Trustee to expend or risk its own funds in the performance of any
     of its duties hereunder, or in the exercise of any of its rights or powers,

     funds or adequate indemnity against such risk is not reasonably assured to
     it.

          (k)  Whether or not herein expressly so provided, every provision of
this Trust Agreement relating to the conduct or affecting the liability of or

Other Note Documents. (a) So long as the Senior Notes are held by the
- --------------------
Trust, the Pass Through Trustee will not (i) direct the time, method and place
of conducting any proceeding for any remedy available to the Indenture Trustee,
or execute any trust or power conferred on the Pass Through Trustee with respect
to the Senior Notes, (ii) waive any past default that is waivable under the
Senior Notes, (iii) exercise any right to rescind or annul a declaration that
the Senior Notes are due and payable, (iv) consent to any amendment,
modification or termination of the Indenture or the Senior Notes, where such
consent is required, without, in each case, complying with the provisions of
Section 11.01(b), or (v) take any other action, except as set forth in Section
11.01(b).

          (b) In the event that the Trust or the Pass Through Trustee on behalf
of the Trust, as holder of any Senior Note in trust for the benefit of the
Certificateholders, receives a request for a consent to any amendment,
modification, waiver or supplement under the Indenture or other Note Document,
which requires the consent of the Certificateholders, the Pass Through Trustee

to direct, (ii) whether or not to give or execute any waivers, consents,
amendments, modifications or Supplements as a holder of such Senior Note and

thereto. Provided such a request for Certificateholder Direction shall have been
made, in directing any action or casting any vote or giving any consent as the
holder of any Senior Note, the Pass Through Trustee shall vote or consent with
respect to such Senior Note in the same proportion as the Certificates were
actually voted by Acts of Holders delivered to the Pass Through Trustee prior to
two Business Days before the Pass Through Trustee directs such action or casts
such vote or gives such consent. Notwithstanding the foregoing, but subject to
Section 7.04, in the case that an Event of Default hereunder shall have occurred
and be continuing, the Pass Through Trustee may, in its own discretion and at
its own direction, consent and notify the Indenture Trustee of such consent to
any amendment, modification, waiver or supplement under the Indenture or other
Note Document.

the last survivor of the descendants of William Clinton, President of the United
States, living on the date of this Trust Agreement.

Special Distribution Date, as the case may be) upon which the Certificateholders
may surrender their Certificates to the Pass Through Trustee for payment of the
final distribution and cancellation, shall be mailed promptly by the Pass
Through Trustee to Certificateholders not earlier than the 60th day and not
later than the 20th day next preceding such final distribution specifying (A)
the Distribution Date (or Special Distribution Date, as the case may be) upon

Record Date otherwise applicable to such Distribution Date (or Special
Distribution Date, as the case may be) is not applicable, payments being made

Certificateholders.  Upon presentation and surrender of the Certificates, the
Pass Through Trustee shall cause to be distributed to Certificateholders amounts
distributable on such Distribution Date or Special Distribution Date, as the

their Certificates for cancellation within six months after the date specified
in the abovementioned written notice, the Pass Through Trustee shall give a

years (or such lesser time as the Pass Through Trustee shall be satisfied, after

provided under applicable law) after the final distribution date with respect
thereto, the Pass Through Trustee shall pay to Indenture Trustee the appropriate
amount of money relating to such Indenture Trustee and shall give written notice
thereof to the Company.

          Upon the winding up of the Trust and its termination, the Pass Through
Trustee shall cause the Certificate of Trust to be canceled by filing a

          Except as set forth in the Guarantee, the Certificates do not
represent a direct obligation of, or an obligation guaranteed by, or an interest
in, the Company or the Pass Through Trustee or any affiliate thereof.  The
Certificates are limited in right of payment, all as more specifically set forth
in the Agreement.  All payments or distributions made to Certificateholders
under the Agreement shall be made only from the Trust Property and only to the
extent that the Paying Agent shall have sufficient income or proceeds from the
Trust Property and only to the extent that the Paying Agent shall have
sufficient income or proceeds from the Trust Property to make such payments in
accordance with the terms of the Agreement.  Each Holder of this Certificate, by
its acceptance hereof, agrees that it will look solely to the income and
proceeds from the Trust Property to the extent available for distribution to
such Holder as provided in the Agreement.  This Certificate does not purport to
summarize the Agreement and reference is made to the Agreement for information
with respect to the interests, rights, benefits, obligations, proceeds, and
duties evidenced hereby.  A copy of the Agreement may be examined during normal
business hours at the principal office of the Pass Through Trustee, and at such
other places, if any, designated by the Pass Through Trustee, by any
Certificateholder upon request.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Certificateholders under the Agreement at any time
by the Company and the Pass Through Trustee with the consent of the Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
a majority in interest in the Trust.  Any such consent by the Holder of this
Certificate shall be conclusive and binding on such Holder and upon all future
Holders of this Certificate and of any Certificate issued upon the transfer
hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate.  The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Registrar, or by any successor Registrar,
duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Registrar, duly executed by the Holder hereof or such
Holder's attorney, duly authorized in writing, and thereupon one or more new
Certificates of authorized denominations evidencing the same aggregate
Fractional Undivided Interest in the Trust will be issued to the designated
transferee or transferees.

          The Certificates are issuable only as registered Certificates without
coupons initially in minimum denominations of $250,000 Fractional Undivided
Interest and any integral multiples of $1,000 in excess thereof.  At such time
as certain restrictions on transfer have been removed, the minimum denominations
of the Certificates shall be reduced to $1,000 or any integral multiples of
$1,000 in excess thereof.  As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of authorized denominations evidencing the same aggregate
Fractional Undivided Interest in the Trust, as requested by the Holder
surrendering the same.

          No service charge will be made for any such registration of transfer
or exchange, but the Pass Through Trustee shall require payment of a sum
sufficient to cover any tax or governmental charge payable in connection
therewith.

          The Pass Through Trustee, the Registrar, and any agent of the Pass
Through Trustee or the Registrar may treat the person in whose name this
Certificate is registered as the owner hereof for all purposes, and neither the
Pass Through Trustee, the Registrar, nor any such agent shall be affected by any
notice to the contrary.

          The obligations and responsibilities created by the Agreement and the
Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them pursuant to
the Agreement and the disposition of all property held as part of the Trust
Property.

        Unless this certificate is presented by an authorized representative of
   The Depository Trust Company, a New York corporation ("DTC"), to Issuer or
   its agent for registration of transfer, exchange, or payment, and any
   certificate issued is registered in the name of Cede & Co. or in such other
   name as is requested by an authorized representative of DTC (and any payment
   is made to Cede & Co. or to such other entity as is requested by an
   authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF
   FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
   registered owner hereof, Cede & Co., has an interest herein.

        2. Issuer: (a) understands that DTC has no obligation to, and will not, 
communicate to its Participants or to any person having an interest in the 
Securities any information contained in the Security certificate(s); and (b) 
acknowledges that neither DTC's Participants nor any person having an interest 
in the Securities shall be deemed to have notice of the provisions of the 
Security certificates by virtue of submission of such certificate(s) to DTC.

        3. In the event of any solicitation of consents from or voting by 
holders of the Securities, Issuer or Agent shall establish a record date for 
such purposes (with no provision for revocation of consents or votes by 
subsequent holders) and shall, to the extent possible, send notice of such 
record date to DTC not less than 15 calendar days in advance of such record 
date. Notices to DTC pursuant to this Paragraph by telecopy shall be sent to 
DTC's Reorganization Department at (212) 709-6896 or (212) 709-6897, and receipt
of such notices shall be confirmed by telephoning (212) 709-6870. Notices to DTC
pursuant to this Paragraph by mail or by any other means shall be sent to DTC's 
Reorganization Department as indicated in Paragraph 5.

        4. In the event of a full or partial redemption, Issuer or Agent send a
notice to DTC specifying: (a) the amount of the redemption or refunding; (b) in 
the case of a refunding, the maturity date(s) established under the refunding; 
and (c) the date such notice is to be mailed to Security holders or published 
(the "Publication Date"). Such notice shall be sent to DTC by a secure means 
(e.g., legible telecopy, registered or certified mail, overnight delivery) in a 
timely manner designed to assure that such notice is in DTC's possession no 
later than the close of business on the business day before or, if possible, two
business days before the Publication Date. Issuer or Agent shall forward such 
notice either in a separate secure transmission for each CUSIP number or in a 
secure transmission for multiple CUSIP numbers (if applicable) which includes a 
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use of such 
means and the timeliness of such notice.) The Publication Date shall be not less
than 30 days nor more than 60 days prior to the redemption date or, in the 
case of an advance refunding, the date that the proceeds are deposited in 
escrow. Notices to DTC pursuant to this Paragraph by telecopy shall be sent to 
DTC's Call Notification Department at (516) 227-4039 or (516) 227-4190. If the 
party sending the notice does not receive a telecopy receipt from DTC confirming
that the notice has been received, such party shall telephone (516) 227-4070. 
Notices to DTC pursuant to this Paragraph by mail or by any other means shall be
sent to:

                Manager; Call Notification Department

        5. In the event of an invitation to tender the Securities (including 
mandatory tenders, exchanges, and capital changes), notice by Issuer or Agent to
Security holders specifying the terms of the tender and the Publication Date of
such notice shall be sent to DTC by a secure means in the manner set forth in 
the preceding Paragraph. Notices to DTC pursuant to this Paragraph and notices 
of other corporate actions by telecopy shall be sent to DTC's Reorganization 
Department at (212) 709-1093 or (212) 709-1094, and receipt of such notices

other means to:

        9. Issuer or Agent shall provide a written notice of interest payment 
information to a standard interest announcement service subscribed to by DTC as 
soon as the information is available. In the unlikely event that no such service
exists, Issuer or Agent shall provide such notice directly to DTC
electronically, as previously arranged by Issuer or Agent and DTC, as soon as
the information is available. If electronic transmission is not available,
absent any other arrangements between Issuer or Agent and DTC, such information
should be sent by telecopy to DTC's Dividend Department at (212) 709-1723 or

                Reorganization Deposit Account # 066-027608

        14. DTC may direct Issuer or Agent to use any other number or address as
the number or address to which notices or payments of interest or principal may 
be sent.

        15. In the event of a redemption, acceleration, or any other similar 
transaction (e.g., tender made and accepted in response to Issuer's or Agent's 
invitation) necessitating a reduction in the aggregate principal amount of 
Securities outstanding or an advance refunding of part of the Securities 
outstanding, DTC, in its discretion: (a) may request Issuer or Agent to issue 
and authenticate a new Security certificate; or (b) may make an appropriate 
notation on the Security certificate indicating the date and amount of such 
reduction in principal except in the case of final maturity, in which case the 
certificate will be presented to Issuer or Agent prior to payment, if required.

        16. In the event that Issuer determines that beneficial owners of 
Securities shall be able to obtain certificated Securities, Issuer or Agent 
shall notify DTC of the availability of certificates. In


                                      -4-
<PAGE>
 
such event, Issuer or Agent shall issue, transfer, and exchange certificates in 
appropriate amounts, as required by DTC and others.

        17. DTC may discontinue providing its services as securities depository
with respect to the Securities at any time by giving reasonable notice to Issuer
or Agent (at which time DTC will confirm with Issuer or Agent the aggregate 
principal amount of Securities outstanding). Under such circumstances, at DTC's 
request Issuer and Agent shall cooperate fully with DTC by taking appropriate
action to make available one or more separate certificates evidencing Securities
to any DTC Participant having Securities credited to its DTC accounts.

        18. Nothing herein shall be deemed to require Agent to advance funds on 
behalf of Issuer.

        19. This Letter of Representations may be executed in any number of 
counterparts, each of which when so executed shall be deemed to be an original, 
but all such counterparts together shall constitute but one and the same 
instrument.

        20. The Letter of Representations is governed by, and shall be construed
in accordance with, the laws of the State of New York.

        21. The following riders, attached hereto, are hereby incorporated into 
this Letter of Representations:

                      SAMPLE OFFICIAL STATEMENT LANGUAGE
                      DESCRIBING BOOK-ENTRY-ONLY ISSUANCE
                      -----------------------------------
 (Prepared by DTC--bracketed material may be applicable only to certain issues)

        1. The Depository Trust Company ("DTC"), New York, NY, will act as 
securities depository for the securities (the "Securities"). The Securities will
be issued as fully-registered securities registered in the name of Cede & Co. 
(DTC's partnership nominee). Only fully-registered Security certificates will be
issued for [each issue of] the Securities, [each] in the aggregate principal 
amount of such issue, and will be deposited with DTC . [If, however, the 
aggregate principal amount of [any] issue exceeds $200 million, one certificate 
will be issued with respect to each $200 million of principal amount and an 
additional certificate will be issued with respect to any remaining principal 
amount of such issue.]

        2. DTC is a limited-purpose trust company organized under the New York 
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC holds securities that its participants ("Participants") deposit
with DTC. DTC also facilitates the settlement among Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Participants' accounts, thereby
eliminating the need for physical movement of securities certificates. Direct
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations, and certain other organizations. DTC is owned by a 
number of its Direct Participants and by the New York Stock Exchange, Inc., the 
American Stock Exchange, Inc., and the National Association of Securities 
Dealers, Inc. Access to the DTC system is also available to others such as 
securities brokers and dealers, banks, and trust companies that clear through or
maintain a custodial relationship with a Direct Participant, either directly or 
indirectly ("Indirect Participants"). The Rules applicable to DTC and its 
Participants are on file with the Securities and Exchange Commission.

        3. Purchasers of Securities under the DTC system must be made by or 
through Direct Participants, which will receive a credit for the Securities on 
DTC's records. The ownership interest of each actual purchaser of each Security 
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect 
Participants' records. Beneficial Owners will not receive written confirmation 
from DTC of their purchase, but Beneficial Owners are expected to receive 
written confirmations providing details of the transactions, as well as periodic
statements of their holdings, from the Direct or Indirect Participant through 
which the Beneficial Owner entered into the transaction. Transfers of ownership 
interests in the Securities are to be accomplished by entries made on the books 
of Participants acting on behalf of Beneficial Owners. Beneficial Owners will 
not receive certificates representing their ownership interests in Securities, 
except in the event that use of the book-entry system for the Securities is 
discontinued.

        4. To facilitate subsequent transfers, all Securities deposited by 
Participants with DTC are registered in the name of DTC's partnership nominee, 
Cede & Co. The deposit of Securities with DTC and their registration in the name
of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of 
the actual Beneficial Owners of the Securities; DTC's records reflect only the
identity of the Direct Participants to whose accounts such Securities are
credited, which may or may not be the Beneficial Owners. The Participants will
remain responsible for keeping account of their holdings on behalf of their 
customers.

        5. Conveyance of notices and other communications by DTC to Direct 
Participants, by Direct  Participants to Indirect Participants, and by Direct 
Participants and Indirect Participants to Beneficial Owners will be governed by 
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.

        [6. Redemption notices shall be sent to DTC. If less than all of the 
Securities within an issue are being redeemed, DTC's practice is to determine by
lot the amount of the interest of each Direct Participant in such issue to be 
redeemed.]


                                      -i-

<PAGE>
 
 
        7. Neither DTC nor Cede & Co. will consent or vote with respect to 
Securities. Under its usual procedures, DTC mails an Omnibus Proxy to Issuer as 
soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s 
consenting or voting rights to those Direct Participants to whose accounts the 
Securities are credited on the record date (identified in a listing attached to
the Omnibus Proxy).

        8. Principal and interest payments on the Securities will be made to 
Cede & Co., as nominee of DTC. DTC's practice is to credit Direct Participants' 
accounts, upon DTC's receipt of funds and corresponding detail information from
Issuer or Agent, on payable date in accordance with their respective holdings
shown on DTC's records. Payments by Participants to Beneficial Owners will be 
governed by standing instructions and customary practices, as is the case with 
securities held for the accounts of customers in bearer form or registered in
"street name," and will be the responsibility of such Participant and not of
DTC. Agent, or Issuer, subject to any statutory or regulatory requirements as
may be in effect from time to time. Payment of principal and interest to Cede &
Co. is the responsibility of Issuer or Agent, disbursement of such payments to
Direct Participants shall be the responsibility of DTC, and disbursement of such
payments to the Beneficial Owners shall be the responsibility of Direct and 
Indirect Participants.

        [9. A Beneficial Owner shall give notice to elect to have its Securities
purchased or tendered, through its Participant, to Agent [or 
Tender/Remarketing Agent] and shall effect delivery of such Securities by 
causing the Direct Participant to transfer the Participant's interest in the 
Securities, on DTC's records, to Agent [or Tender/Remarketing Agent]. The 
requirement for physical delivery of Securities in connection with an optional 
tender or a mandatory purchase will be deemed satisfied when the ownership 
rights in the Securities are transferred by Direct  Participants on DTC's 
records and followed by a book-entry credit of tendered Securities to Agent [or 
Tender/Remarketing Agent's] DTC Account.]

        10. DTC may discontinue providing its services as securities depository 
with respect to the Securities at any time by giving reasonable notice to Issuer
or Agent. Under such circumstances, in the event that a successor securities 
depository is not obtained, Security certificates are required to be printed and
delivered.

        11. Issuer may decide to discontinue use of the system of book-entry 
transfers through DTC (or a successor securities depository). In that event, 
Security certificates will be printed and delivered.

        12. The information in this section concerning DTC and DTC's book-entry 
system has been obtained from sources that Issuer believes to be reliable, but 
Issuer takes no responsibility for the accuracy thereof.

                   REPRESENTATIONS FOR RULE 144A SECURITIES--
                to be included in DTC Letter of Representations

        1. Issuer represents that at the time of initial registration in the
name of DTC's nominee, Cede & Co., the Securities were Legally or Contractually
Restricted Securities,/1/ eligible for transfer under Rule 144A under the
Securities Act of 1933, as amended (the "Securities Act"), and identified by a
CUSIP or CINS identification number that was different from any CUSIP or CINS
number assigned to any securities of the same class that were not Legally or
Contractually Restricted Securities. Issuer shall ensure that a CUSIP or CINS
identification number is obtained for all unrestricted securities of the same
class that is different from any CUSIP or CINS identification number assigned to
a Legally or Contractually Restricted Security of such class, and shall notify
DTC promptly in the event that it is unable to do so. Issuer represents that it
has agreed to comply with all applicable information requirements of Rule 144A.

        2.  Issuer represents that the Securities are [Note: Issuer must 
represent one of the following, and may cross out the other]

[included within                 , a Self-Regulatory Organization system 
approved by the Securities and Exchange Commission for the reporting of 
quotation and trade information of securities eligible for transfer pursuant to 
Rule 144A (an "SRO 144A System").]

        3. If the Securities are not Investment-Grade Securities, Issuer and
Agent acknowledge that if such Securities cease to be included in an SRO Rule
144A System during any period in which such Securities are Legally or
Contractually Restricted Securities, such Securities shall no longer be eligible
for DTC's services. Furthermore, DTC may discontinue providing its services as
securities depository with respect to the Securities at any time by giving
reasonable notice to Issuer or Agent. Under any of the aforementioned
circumstances, at DTC's request, Issuer and Agent shall cooperate fully with DTC
by taking appropriate action to make available one or more separate certificates
evidencing Securities to any Participant having Securities credited to its DTC
accounts .

- ----------
        /1/ A "Legally Restricted Security" is a security that is a restricted
security, as defined in Rule 144(a)(3). A "Contractually Restricted Security" is
a security that upon issuance and continually thereafter can only be sold
pursuant to Regulation S under the Securities Act, Rule 144A, Rule 144, or in a
transaction exempt from the registration requirements of the Securities Act
pursuant to Section 4 of the Securities Act and not involving any public
offering; provided, however, that once the security is sold pursuant to the
provisions of Rule 144, including Rule 144(k), it will thereby cease to be a
"Contractually Restricted Security." For purposes of this definition, in order
for a depositary receipt to be considered a "Legally or Contractually Restricted
Security," the underlying security must also be a "Legally or Contractually
Restricted Security."

<PAGE>
 
        4. Issuer and Agent acknowledge that so long as Cede & Co. is a record
owner of the Securities, Cede & Co. shall be entitled to all applicable voting
rights and to receive the full amount of all distributions payable with respect
thereto. Issuer and Agent acknowledge that DTC shall treat any DTC Participant
("Participant") having Securities credited to its DTC accounts as entitled to
the full benefits of ownership of such Securities. Without limiting the
generality of the preceding sentence, Issuer and Agent acknowledge that DTC
shall treat any Participant having Securities credited to its DTC accounts as
entitled to receive distributions (and voting rights, if any) in respect to
Securities, and to receive from DTS certificates evidencing Securities, Issuer
and Agent recognize that DTC does not in any way undertake to, and shall not
have any responsibility to, monitor or ascertain the compliance of any
transactions in the Securities with any of the provisions: (a) of Rule 144A; (b)
of other exemptions from registration under the Securities Act or of any other

Ladies and Gentlemen:

                  In connection with our proposed purchase of $______________
aggregate principal amount of the Certificates, we confirm that:

                  1. We understand that any subsequent transfer of the
     Certificates is subject to certain restrictions and conditions set forth in
     the Pass Through Trust Agreement dated as of _________ __, 1997 relating to
     the Certificates and the undersigned agrees to be bound by, and not to
     resell, pledge or otherwise transfer the Certificates except in compliance
     with, such restrictions and conditions and the Securities Act of 1933, as
     amended (the "Securities Act").

                  2. We understand that the Certificates have not been
     registered under the Securities Act, and that the Certificates may not be
     offered or sold except as permitted in the following sentence. We agree, on
     our own behalf and on behalf of any accounts for which we are acting as
     hereinafter stated, that if we should sell any Certificates within two
     years after the original issuance of the Certificates, we will do so only
     (A) to the Company or any subsidiary thereof, (B) inside the United States
     in accordance with Rule 144A under the Securities Act to a "qualified
     institutional buyer" (as defined therein), (C) inside the United States to
     an "institutional accredited investor" (as defined below) that, prior to
     such transfer, furnishes (or has furnished on its behalf by a U.S. broker-
     dealer) to you a signed letter substantially in the form of this letter,
     (D) outside the United States in accordance with Rule 904 of Regulation S
     under the Securities Act, (E) pursuant to the exemption from registration
     provided by Rule 144 under the Securities Act (if available), or (F)
     pursuant to an effective registration statement under the Securities Act,
     and we further agree to provide to any person purchasing any of the
     Certificates from us a notice advising such purchaser that resales of the
     Certificates are restricted as stated herein.

                                      F-1

<PAGE>
 
                  3. We understand that, on any proposed resale of any
     Certificates, we will be required to furnish to you and the Company such
     certification, written legal opinions and other information as you and the
     Company may reasonably require to confirm that the proposed sale complies
     with the foregoing restrictions. We further understand that the
     Certificates purchased by us will bear a legend to the foregoing effect.

                  4. We are an institutional "accredited investor" (as defined
     in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
     Act) and 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 Certificates, and we and any accounts for which we are
     acting are each able to bear the economic risk of our or its investment, as
     the case may be.

                  5. We are acquiring the Certificates purchased by us for our
     own account or for one or more accounts (each of which is an institutional
     "accredited investor") as to each of which we exercise sole investment
     discretion.

                  You, the Trust, the Pass Through Trustee, the Company and
counsel for the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested

- ------------------------------------                                        
liability under this Agreement shall be limited as follows:  (i) the Escrow
Agent does not represent, warrant or guaranty to the holders of the Notes from
time to time the performance of the Company; (ii) the Escrow Agent shall have no
responsibility to the Company or the holders of the Notes or the Indenture
Trustee from time to time as a consequence of performance by the Escrow Agent
hereunder, except for any gross negligence or willful misconduct of the Escrow
Agent; (iii) the Company shall remain solely responsible for all aspects of the
Company's business and conduct; and (iv) the Escrow Agent is not obligated to
supervise, inspect, or inform the Company or any third party of any matter
referred to above.


     No implied covenants or obligations shall be inferred from this Agreement
against the Escrow Agent, nor shall the Escrow Agent be bound by provisions of
any agreement beyond the specific term hereof.  Specifically and without
limiting the foregoing, the Escrow Agent shall in no event have any liability in
connection with its investment, reinvestment or liquidation, in good faith and
in accordance with the terms hereof, of any funds or Marketable Securities held
by it hereunder, including without limitation, any liability for any delay not
resulting from gross negligence or willful misconduct in such investment,
reinvestment or liquidation, or for any loss of principal or income incident to
any such delay.


     The Escrow Agent shall be entitled to rely upon any judicial order or
judgment, upon any written opinion of counsel or upon any certification,
instruction, notice, or other writing delivered to it by the Company or the
Indenture Trustee in compliance with the provisions of this Agreement without
being required to determine the authenticity or the correctness of any fact
stated therein or the propriety or validity of service thereof. The Escrow Agent
may act in reliance upon any instrument comporting with the provisions of this
Agreement or signature believed by it to be genuine and may assume that any
person purporting to give notice or receipt or advice or make any statement or
execute any document in connection with the provisions hereof has been duly
authorized to do so.


     At any time the Escrow Agent may request in writing an instruction in
writing from the Company, and may at its own option include in such request the
course of action it proposes to take and the date on which it proposes to act,
regarding any matter arising in connection with its duties and obligations
hereunder; provided, however, that the Escrow Agent shall state in such request
           --------  -------                                                   
that it believes in good faith that such

                                      -11-
<PAGE>
 
proposed course of action is consistent with another identified provision of
this Agreement.  The Escrow Agent shall not be liable to the Company for acting
without the Company's consent in accordance with such a proposal on or after the
date specified therein if (i) the specified date is at least two (2) Business
Days after the Company receives the Escrow Agent's request for instructions and
its proposed course of action, and (ii) prior to so acting, the Escrow Agent has
not received the written instructions requested from the Company.


     The Escrow Agent may act pursuant to the written advice of counsel chosen
by it with respect to any matter relating to this Agreement and (subject to
Section 4(ii)) shall not be liable for any action taken or omitted in accordance
with such advice.


     The Escrow Agent shall not be called upon to advise any party as to selling
or retaining, or taking or refraining from taking any action with respect to,
any securities or other property deposited hereunder.


     In the event of any ambiguity in the provisions of this Agreement with
respect to any funds or property deposited hereunder, the Escrow Agent shall be
entitled to refuse to comply with any and all claims, demands or instructions
with respect to such property or funds, and the Escrow Agent shall not be or
become liable for its failure or refusal to comply with conflicting claims,
demands or instructions.  The Escrow Agent shall be entitled to refuse to act
until either any conflicting or adverse claims or demands shall have been
finally determined by a court of competent jurisdiction or settled by agreement
between the conflicting claimants as evidenced in a writing, satisfactory to the
Escrow Agent, or the Escrow Agent shall have received security or an indemnity
satisfactory to the Escrow Agent sufficient to save the Escrow Agent harmless
from and against any and all loss, liability or expense which the Escrow Agent
may incur by reason of its acting.  The Escrow Agent may in addition elect in
its sole option to commence an interpleader action or seek other judicial relief
or orders as the Escrow Agent may deem necessary.


     No provision of this Agreement shall require the Escrow Agent to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder.


     5.   Indemnity.  The Company shall indemnify, hold harmless and defend the
          ---------                                                            
Escrow Agent and its directors, officers, agents, employees and controlling
persons, from and against any and all claims, actions, obligations, liabilities
and expenses, including defense costs, investigative fees and costs, legal fees,
and claims for damages, arising from the Escrow Agent's performance under this
Agreement, except to the extent that such liability, expense or claim is
attributable to the gross negligence or

                                      -12-
<PAGE>
 
willful misconduct of any of the foregoing persons.  In connection with any
claim, action, obligation, liability or expense for which indemnification is
sought by the Escrow Agent hereunder, the Escrow Agent shall be entitled to
recover its costs from funds available in the each Account as provided in
Section 2(c), provided, however, that the Company agrees to pay such costs if
              --------  -------                                              
funds in any Account are insufficient.  The provisions of this Section shall
survive any termination, satisfaction or discharge of this Agreement as well as
the resignation or removal of the Escrow Agent.



     6.   Grant of Security Interest; Instructions to Escrow Agent.
          -------------------------------------------------------- 


               (a)  The Company hereby irrevocably grants a valid and
enforceable first priority security interest in, pledges, assigns and sets over
to the Indenture Trustee all of the Company's right, title and interest in and
to each Account, all funds held therein and all Marketable Securities held by
(or otherwise maintained in the name of) the Escrow Agent pursuant to Section 2
hereof, any and all financial assets and security entitlements of the Company in
any and all of the foregoing, any and all rights of the Company under this
Agreement and any and all proceeds of any and all of the foregoing
(collectively, the "Collateral"), in order to secure all obligations and
                    ----------
indebtedness of the Company under the Notes and any other obligation, now or
hereafter arising, of every kind and nature, owed by the Company under the
Indenture to the holders of the Notes or to the Indenture Trustee. The Company
shall take all reasonable actions necessary on its part to insure the
continuance of a valid and enforceable first priority perfected security
interest in the Collateral in favor of the Indenture Trustee in order to secure
all such obligations and indebtedness.


               (b)  The Company and the Indenture Trustee hereby irrevocably
instruct the Escrow Agent to, and the Escrow Agent will (i) hold all funds in
each Account for the exclusive benefit of the Indenture Trustee to the extent
specifically required herein, (ii) maintain, or cause its agent within the State
of New York to maintain, possession of all certificated Marketable Securities
purchased hereunder that are physically possessed by the Escrow Agent in order
for the Indenture Trustee to enjoy a continuous valid and enforceable first
priority perfected security interest therein under the law of the State of New
York (the Company hereby agreeing that in the event any certificated Marketable
Securities are in the possession of the Company or a third party, the Company
shall use its best efforts to deliver all such certificates to the Escrow
Agent), (iii) take all steps set forth in the opinion of counsel described in
paragraph (a) above to cause the Indenture Trustee to enjoy a continuous valid
and enforceable first priority perfected security interest under the New York
Uniform Commercial Code and any applicable law of the State of New York in all
Marketable Securities purchased hereunder that are not certificated and (iv)
maintain

                                      -13-
<PAGE>
 
the Collateral free and clear of all liens, security interests, safekeeping or
other charges, demands and claims against the Escrow Agent of any nature now or
hereafter existing in favor of anyone other than the Indenture Trustee; (v)
promptly notify the Indenture Trustee if the Escrow Agent receives written
notice that any person other than the Indenture Trustee has a lien or security
interest upon any portion of the Collateral (other than any claim which Escrow
Agent may have against any Account for unpaid fees and expenses) and (vi) in
addition to disbursing amounts held in escrow pursuant to any Escrow Account
Payment Notice and Disbursement Request given to it by the Indenture Trustee or
any Refinancing Account Payment Notice and Disbursement Request given to it by
the Company, in each case pursuant to Section 3, upon receipt of written notice
from the Indenture Trustee of the acceleration of the maturity of the Notes or
the failure by the Company to pay principal on the Notes, and direction from the
Indenture Trustee to disburse all Available Funds to the Indenture Trustee, as
promptly as practicable, after following the procedures set forth in the fourth
paragraph of Section 4(a), disburse all funds held in each Account to the
Indenture Trustee and transfer title to all Marketable Securities held by the
Escrow Agent hereunder to the Indenture Trustee.  The lien and security interest
provided for by this Section 6 shall automatically terminate and cease as to,
and shall not extend or apply to, and the Indenture Trustee shall have no
security interest in, any funds disbursed by the Escrow Agent to the Company
pursuant to this Agreement.  The Escrow Agent shall act solely as the Indenture
Trustee's agent in connection with the duties under this Section 6,
notwithstanding any other provision contained in this Agreement, without any
right to receive compensation from the Indenture Trustee and without any
authority to obligate the Indenture Trustee or to compromise or pledge its
security interest hereunder.


               (c)  Any money and Marketable Securities collected by the
Indenture Trustee pursuant to Section 6(b) shall be applied as provided in the
Indenture.


               (d)  Upon demand, the Company will execute and deliver to the
Indenture Trustee such instruments and documents as the Indenture Trustee may
reasonably deem necessary or advisable to maintain or perfect the rights of the
Indenture Trustee under this Agreement and the Indenture Trustee's interest in
the Collateral. The Indenture Trustee will take all necessary action to preserve
and protect the security interest created hereby as a valid and enforceable
first priority perfected lien and encumbrance upon the Collateral.


               (e)  The Company hereby appoints the Indenture Trustee as its
attorney-in-fact effective upon and during the continuance of an Event of
Default under the Indenture with full power of substitution to do any act which
the Company is obligated hereto to do, and the Indenture Trustee may exercise
such rights as the

                                      -14-
<PAGE>
 
Company might exercise with respect to the Collateral and to take any action in
the Company's name to protect the Indenture Trustee's security interest
hereunder.


          (f)  (i) Notwithstanding the provisions of Section 2(d), (x) until the
Escrow Agent has received notice from the Indenture Trustee that its security
interest in the rights and assets in the Escrow Account or the Refinancing
Account has been released, an authorized officer of Indenture Trustee may give
any written instructions of any kind or character in regard to the Escrow
Account or the Refinancing Account or any securities or other assets in the
Escrow Account or the Refinancing Account (including, without limitation,
instructions and orders with respect to the sale, or other disposition, transfer
or redemption of any securities or other assets in the Escrow Account or the
Refinancing Account), and the Escrow Agent agrees to comply with such
instructions without further action or consent by the Company or Indenture
Trustee; (y) with respect to any instructions given in accordance with this
Section 2(f) it is hereby understood and agreed that the Escrow Agent shall have
no duty nor authority whatsoever of any kind of character to determine whether
or not such instructions, or any certification or other statement contained
therein, are correct or given in conformity with the Indenture Trustee's rights
pursuant to any other agreement, nor to seek conformity with the Indenture
Trustee's rights pursuant to any other agreement, nor to seek confirmation
thereof from the Company or the Indenture Trustee; and (z) pursuant to this
Section 2(f), the Indenture Trustee hereby instructs the Escrow Agent to credit
any proceeds, income, distributions (in cash or in kind) and any other amounts
or property deriving from any securities or other property in the Escrow Account
or the Refinancing Account, as the case may be, to the Escrow Account or the
Refinancing Account, as the case may be, and to hold all money or cash credited
(or required to be credited) to the Escrow Account or the Refinancing Account,
as the case may be, as Collateral hereunder, and the Escrow Agent hereby agrees
that it will comply with such instruction absent any instructions from the
Indenture Trustee to the contrary.


          (g)  By this Agreement the Company and Indenture Trustee intend and
agree that the Indenture Trustee has obtained "control" (within the meaning of
Section 8-106(d) of the UCC of the Escrow Account and the Refinancing Account
and the respective assets in the Escrow Account and the Refinancing Account.


          (h)  Until the Escrow Agent has received notice from the Indenture
Trustee that its security interest in the Collateral has been released, the
Escrow Agent shall not exercise any right of combination, consolidation, merger
or set-off which the Escrow Agent may have in respect of any Collateral.

     7.   Termination.  This Agreement shall terminate automatically ten (10)
          -----------                                                        
days following disbursement of all funds remaining in each Account (including
Marketable Securities), unless sooner terminated by agreement of the parties
hereto (in accordance with the terms hereof and not in violation of the
Indenture); provided, however, that the obligations of the Company under Section
            --------  -------                                                   
5 (and any existing claims thereunder) shall survive termination of this
Agreement or the resignation of the Escrow Agent; and provided further, that
                                                      -------- -------      
until such tenth day, the Company will cause this Agreement (or any permitted
successor agreement) to remain in effect and will cause there to be an escrow
agent (including any permitted successor thereto) acting hereunder (or under any
such permitted successor agreement).

               (a)  Waiver. Any party hereto may specifically waive any breach
                    ------
of this Agreement by any other party, but no such waiver shall be deemed to have
been given unless such waiver is in writing, signed by the waiving party and
specifically designating the breach waived, nor shall any such waiver constitute
a continuing waiver of similar or other breaches.


               (b)  Invalidity. If for any reason whatsoever any one or more of
                    ----------
the provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid in a particular case or in all cases, such
circumstances shall not have the effect of rendering any of the other provisions
of this Agreement inoperative, unenforceable or invalid, and the inoperative,
unenforceable or invalid provision shall be construed as if it were written so
as to effectuate, to the maximum extent possible, the parties' intent.


               (c)  Assignment. This Agreement is personal to the parties
                    ----------
hereto, and the rights and duties of any party hereunder shall not be assignable
except with the prior written consent of the other parties. Notwithstanding the
foregoing, this Agreement shall inure to and be binding upon the parties and
their successors and permitted assigns.


               (d)  Benefit. The parties hereto and their successors and
                    -------
permitted assigns, but no others, shall be bound hereby and entitled to the
benefits hereof; provided, however, that the holders of the Notes and their
                 --------  -------
permitted assigns shall be entitled to the benefits hereof and to enforce this
Agreement.


               (e)  Time.  Time is of the essence of each provision of this

                    -----------------------------------------------------------
THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT, AND THE TERMS AND CONDITIONS
SET FORTH HEREIN, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED WHOLLY
THEREIN, WITHOUT GIVING EFFECT TO ANY PROVISIONS THEREOF RELATING TO CONFLICTS
OF LAW. THE PARTIES HERETO INTENDED AND, TO THE EXTENT PERMITTED BY APPLICABLE
LAW, AGREE THAT THIS IS AN AGREEMENT BETWEEN A SECURITIES INTERMEDIARY AND ITS
ENTITLEMENT HOLDER FOR PURPOSES OF 31 C.F.R. 357.11(b)(1) AND (S)8-110(e)(1) OF
THE UCC.


     Each of the parties hereto irrevocably agrees that any legal dispute,
action or proceeding arising out of or based upon this Agreement may be
instituted in any New York State or U.S. Federal court sitting in the Borough of
Manhattan, New York City,

                                      -18-
<PAGE>
 
New York, U.S.A. (each a "New York Court" and collectively, the "New York
Courts"), irrevocably waives, to the extent permitted by applicable law, any
objection which it may now or hereafter have to the laying of venue to any such
proceeding and irrevocably submits to the non-exclusive jurisdiction of such
courts in any such suit, action or proceeding.  The Company has appointed CT
Corporation Systems, Inc., 1633 Broadway, New York, New York 10019, as its
authorized agent ("Authorized Agent") to receive on its behalf service of copies
of the summons and complaints and any other process which may be served in any
legal suit, action or proceeding arising out of or relating to this Agreement
which may be instituted in any federal or state court sitting in The City of New
York, expressly consents to the jurisdiction of any such court in respect of any
such action, and waives any other requirements of or objections to personal
jurisdiction with respect thereto.  Such appointment shall be irrevocable for a
period of three years from the date of this Agreement.  Such service may be made
by delivering a copy of such process to the Company in care of the Authorized
Agent at the address specified above for the Authorized Agent and obtaining a
receipt therefor, and the Company hereby irrevocably authorizes and directs such
Authorized Agent to accept such service on its behalf.  The Company represents
and warrants that the Authorized Agent has agreed to act as said agent for
service of process, and agrees that service of process in such manner upon the
Authorized Agent shall be deemed in every respect effective service of process
upon the Company in any such suit, action or proceeding.  The Company further
agrees to take any and all actions as may be necessary to maintain such
designation and appointment of such Authorized Agent in full force and effect.
If the Authorized Agent shall cease to act as the Company's agent in The City of
New York for service of process, the Company shall appoint without delay another
such agent and notify the Escrow Agent of such appointment.


               (k)  To the extent that the Company or any of its revenues,
assets or properties shall be entitled, with respect to any proceeding at any
time brought against the Company or any of its revenues, assets or properties or
with respect to any suit, action or proceeding at any time brought for the
purpose of enforcing or executing any judgment in any jurisdiction in which any
specified court or other court is located, to any immunity from suit, from the
jurisdiction of any such court, from attachment prior to judgment, from
attachment in aid of execution of judgment, from execution of a judgment or from
any other legal or judicial process or remedy, to the extent of such immunity,
the Company irrevocably agrees not to claim and irrevocably waives such immunity
to the fullest extent permitted by the laws of such jurisdiction (including
without limitation, the Foreign Sovereign Immunities Act of 1976 of the United
States).

               (l)  The Company hereby represents and warrants that this
Agreement has been duly authorized, executed and delivered on its behalf and
constitutes the legal, valid and binding obligation of the Company enforceable
in

                                      -19-
<PAGE>
 
accordance with its terms.  The execution, delivery and performance of this
Agreement by the Company does not violate any applicable law or regulation to
which the Company is subject or any organizational document of the Company and
does not require the consent of any governmental or other regulatory body to
which the Company is subject, except for such consents and approvals as have
been obtained and are in full force and effect.


               (m)  Each of the Escrow Agent and the Indenture Trustee hereby
represents and warrants that this Agreement has been duly authorized, executed
and delivered on its behalf and constitutes its legal, valid and binding
obligation.

          WHEREAS, the Guarantor, Wilmington Trust Company (the "Pass Through
Trustee") and the Guarantee Trustee, as registrar and paying agent, have entered
into the Amended and Restated Pass Through Trust Agreement dated as of October
28, 1997 (such agreement, including all exhibits thereto, as it may from time to
time be amended, modified or supplemented, is hereinafter referred to as the
"Trust Agreement"), pursuant to which Transtel Pass Through Trust (the "Trust")
issued the Exchange Certificates to the Exchange Certificateholders;

          WHEREAS, the Guarantor executed and delivered on October 28, 1997 a
guarantee agreement (the "Original Certificate Guarantee"), with substantially
identical terms to this Guarantee, for the benefit of the Original
Certificateholders;

          WHEREAS, as an incentive for the holders (the "Original
Certificateholders") of 12 1/2% Pass Through Trust Certificates due 2007,
representing interests in 12 1/2% Senior Notes issued by the Guarantor (the
"Original Certificates") to exchange their Original Certificates for Exchange
Certificates, the Guarantor desires irrevocably and unconditionally to agree, to
the extent set forth in this Guarantee, to be obligated to the Exchange
Certificateholders under the Guaranteed Obligations (as defined herein);

     NOW, THEREFORE, in consideration of the exchange by Original
Certificateholders of Original Certificates for Exchange Certificates which
exchange the Guarantor hereby acknowledges shall benefit the Guarantor, and for
other good and valuable consideration, receipt and sufficiency of which is
hereby acknowledged, the Guarantor hereby represents and warrants to, and
covenants and agrees with the Guarantee Trustee and the Exchange
Certificateholders, as follows:
<PAGE>
 
     1.  The Guarantor hereby irrevocably and unconditionally guarantees to the
Exchange Certificateholders (a) the punctual payment of the full amount, when
due (whether by demand, acceleration or otherwise), of the principal of and
interest on, and fees and expenses due pursuant to, the Exchange Certificates,
and (b) full and timely payment on the Exchange Certificates as if payment had
been made on a full and timely basis on the Senior Notes (all of the liabilities
and obligations included in clauses (a) and (b) of this paragraph 1 are
hereinafter referred to collectively as the "Guaranteed Obligations").  This is
a guaranty of payment and not of collection, and is the primary obligation of
the Guarantor; and Guarantee Trustee, on behalf of the Exchange
Certificateholders, may enforce this Guarantee against the Guarantor without any
prior enforcement of the Guaranteed Obligations against the Trust.  Any action
to enforce this Guarantee shall be undertaken by the Guarantee Trustee upon the
written direction of Exchange Certificateholders representing not less than a
majority of the outstanding Exchange Certificates.

     2.  All payments made by the Guarantor under or by virtue of this Guarantee
shall be paid to the Guarantee Trustee at its office at 140 Broadway, 12th
Floor, New York, New York 10005, U.S.A. or such other place as the Guarantee
Trustee may hereafter designate in writing.  The Guarantor hereby agrees to make
all payments under or by virtue of this Guarantee to the Guarantee Trustee, on
behalf of the Exchange Certificateholders, as aforesaid.  The Guarantee Trustee
shall not be required otherwise to establish its authority to receive any
payment made hereunder.  During such time as the Guarantee Trustee is acting as
paying agent under the Trust Agreement, the Guarantee Trustee shall apply any
payments received under this Guarantee in its capacity as paying agent as
provided under the Trust Agreement.  Following such time as the Guarantee
Trustee ceases to be paying agent under the Trust Agreement, the Guarantee
Trustee shall pay any payments received hereunder to the successor paying agent
or the Guarantee Trustee for payment in accordance with the terms of the Trust
Agreement.

     3.  The Guarantor hereby waives notice of acceptance of this Guarantee,
notice of the creation, renewal or accrual of any of the Guaranteed Obligations
and notice of any other liability to which this Guarantee may apply, and notice
or proof of reliance by the Exchange Certificateholders upon this Guarantee, and
waives diligence, protest, notice of protest, presentment, demand of payment,
notice of dishonor or nonpayment of any of the Guaranteed Obligations, suit or
taking other action or making any demand against, and any other notice to the
Trust or any other party liable thereon.

     4.  So far as the Guarantor is concerned, the Guarantee Trustee or the
Exchange Certificateholders may, at any time and from time to time, without the
consent of, or notice to the Guarantor, and without impairing or releasing any
of the obligations of the Guarantor hereunder, upon or without any terms or
conditions and in whole or in part:

     (a)  exercise or refrain from exercising any rights against the Pass 
Through Trustee, the Trust or others or otherwise act or refrain from acting; 
and

                                       2
<PAGE>
 
     (b)  to the extent set forth in the Trust Agreement, amend or otherwise
modify the Trust Agreement, consent to or waive any breach of, or any act,
omission or default under the Trust Agreement, the Exchange Certificates, or any
agreements, instruments or documents referred to therein or executed and
delivered pursuant thereto or in connection therewith, and this Guarantee shall
apply to the Guaranteed Obligations as set forth in each of such documents as so
amended and modified. Any such action shall not impair or release any of the
obligations of the Guarantor hereunder.

     5.  No invalidity, irregularity or unenforceability of all or any part of
the Guaranteed Obligations or of any security therefor shall affect, impair or
be a defense to this Guarantee, and this Guarantee shall be construed as a
continuing, absolute and unconditional guarantee of payment without regard to
the validity, regularity or enforceability of the Trust Agreement, the Exchange
Certificates or any of the other Guaranteed Obligations or any collateral
security therefor or guaranty thereof or rights of offset with respect thereto
at any time or from time to time held by the Exchange Certificateholders and
without regard to any defense, offset or counterclaim which may at any time be
available to or be asserted by the Trust against the Exchange Certificateholders
and which constitutes, or might be construed to constitute, an equitable or
legal discharge of the Trust for the Guaranteed Obligations or any part thereof,
or of the Guarantor under this Guarantee, bankruptcy or in any other instance.

     6.  Until such time that the Guaranteed Obligations are paid in full, the
Guarantor hereby irrevocably waives, for the benefit of the Exchange
Certificateholders, any and all rights which it presently has, or may hereafter
have, whether by virtue of any payment or payments hereunder or otherwise, to be
subrogated to the rights of the Exchange Certificateholders against the Trust
with respect to any indebtedness of the Trust to the Exchange
Certificateholders.

Certificates evidencing not less than a 25% interest in the Trust delivered to
the Guarantor, the Pass Through Trustee and the retiring Guarantee Trustee, the

the corporate trust business of the Guarantee Trustee, shall be the successor of
the Guarantee Trustee hereunder, provided such corporation shall be otherwise

                             -------------------------------------          
Exchange Offer shall comply with all applicable tender offer rules and
regulations under the Exchange Act.  The Company and the Trust shall use its
best efforts to cause the Exchange Offer Registration Statement to be declared
effective by the SEC under the Securities Act on or before the Effectiveness
Date.  Upon the Exchange Offer Registration Statement being declared effective,
the Trust shall offer the Exchange Certificates in exchange for the surrender of
the Certificates.  The Company shall use its best efforts to keep the Exchange
Offer open for at least 30 calendar days (or longer if required by applicable
law) after the date that notice of the Exchange Offer is mailed to Holders.  For
purposes of this Section 2(a) only, if after such Exchange Offer Registration
Statement is initially declared effective by the SEC, the Exchange Offer or the
issuance of the Exchange Certificates pursuant to the Exchange Offer is
interfered with by any stop order, injunction or other order or requirement of
the SEC or any other governmental agency or court, such Exchange Offer
Registration Statement shall be deemed not to have become effective for purposes
of this Agreement.  Each Holder who participates in the Exchange Offer will be
required to represent and warrant that any Exchange Certificate received by such
Holder in connection with the Exchange Offer will be acquired by such Holder in
the ordinary course of such Holder's business, that at the time of the
consummation of the Exchange Offer such Holder will have no arrangement or
understanding with any Person to participate in the distribution of the Exchange
Certificates in violation of the provisions of the Securities Act, and that such
Holder is not an affiliate of the Company

                                      -6-
<PAGE>
 
or the Trust within the meaning of the Securities Act or, if it is an affiliate,
it will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable.  Upon consummation of the Exchange
Offer in accordance with this Section 2, the provisions of this Agreement shall
continue to apply, mutatis mutandis, solely with respect to Registrable
                   ------- --------                                    
Certificates that are Private Exchange Certificates and Exchange Certificates
held by Participating Broker-Dealers, and the Company shall have no further
obligation to register Registrable Certificates pursuant to Section 3 hereof
(other than Private Exchange Certificates and other than in respect of any
Exchange Certificates as to which clause 2(c)(iv) hereof applies).  No
securities other than the Exchange Certificates shall be included in the
Exchange Offer Registration Statement.

          (b)  The Company shall include within the Prospectus included in the
Exchange Offer Registration Statement a section entitled "Plan of Distribution,"
reason ably acceptable to the Initial Purchaser in form and substance, which
shall contain a summary statement of the positions taken or policies made by the
Staff of the Division of Corporation Finance of the SEC (the "Staff") with
                                                              -----       
respect to the potential "underwriter" status of any broker-dealer that is the
beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange
Certificates received by such broker-dealer pursuant to the Exchange Offer (a
                                                                             
"Participating Broker-Dealer"), whether such positions or policies have been
 ---------------------------                                                
publicly disseminated by the Staff or whether such positions or policies, in the
judgment of the Initial Purchaser, represent the prevailing views of the Staff.
Such "Plan of Distribution" section shall also expressly permit the use of the
Prospectus by all Persons subject to the prospectus delivery requirements of the
Securities Act, including all Participating Broker-Dealers, and include a
statement describing the means by which Participating Broker-Dealers may offer
and resell the Exchange Certificates.

          The Company shall use its best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the Prospectus
contained therein as may be required by the Securities Act, in order to permit
such Prospectus to be lawfully delivered by all Persons subject to the
prospectus delivery requirements of the Securities Act for such period of time
as is necessary to comply with applicable law in connection with any resale of
the Exchange Certificates; provided, however, that such period shall not exceed
                           --------  -------                                   
180 days after the Exchange Offer Registration Statement is declared effective
(or such longer period if extended pursuant to the last paragraph of Section 5
hereof) (the "Applicable Period").
              -----------------   

          If, prior to consummation of the Exchange Offer, the Initial Purchaser
holds any Certificates acquired by it and having, or which are reasonably likely
to be determined to have, the status of an unsold allotment in the initial
distribution, or any

                                      -7-
<PAGE>
 
other Holder is not entitled to participate in the Exchange Offer, the Company
upon the request of the Initial Purchaser or any such Holder shall
simultaneously with the delivery of the Exchange Certificates in the Exchange
Offer, issue and deliver to the Initial Purchaser and any such Holder, in
exchange (the "Private Exchange") for such Certificates held by such Initial
               ----------------                                             
Purchaser and any such Holder, a like principal amount of certificates issued by
the Trust that are identical in all material respects to the Exchange
Certificates (the "Private Exchange Certificates") (and which are entitled to
                   -----------------------------                             
the benefits of the Trust Agreement or a trust agreement which is identical in
all material respects to the Trust Agreement); provided, however, the Company
                                               --------  -------             
shall not be required to effect such exchange if, in the written opinion of
counsel for the Company (a copy of which shall be in form and substance
reasonably satisfactory to the Initial Purchaser and be delivered to the Initial
Purchaser and any Holder affected thereby), such exchange cannot be effected
without registration under the Securities Act.  The Private Exchange
Certificates shall bear the same CUSIP number as the Exchange Certificates.

          Interest on the Senior Notes underlying the Exchange Certificates and
the Private Exchange Certificates will accrue from (A) the later of (i) the last
interest payment date on which interest was paid on the Senior Notes underlying
the surrendered Certificates surrendered in exchange therefor or (ii) if the
Certificates are surrendered for exchange on a date in a period which includes
the record date for an interest payment date on such Senior Notes to occur on or
after the date of such exchange and as to which interest will be paid, the date
of such interest payment date or (B) if no interest has been paid on such Senior
Notes, from the Issue Date.

          In connection with the Exchange Offer, the Company, on behalf of the
Trust, shall:

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

          (ii)   utilize the services of a depositary for the Exchange Offer
     with an address in the Borough of Manhattan, The City of New York;

          (iii)  permit Holders to withdraw tendered Certificates at any time
     prior to the close of business, New York time, on the last business day on
     which the Exchange Offer shall remain open; and

          (iv)   otherwise comply in all material respects with all applicable
     laws, rules and regulations.

                                      -8-
<PAGE>
 
          As soon as practicable after close of the Exchange Offer or the
Private Exchange, as the case may be, the Company shall:

          (i)    accept for exchange all Certificates tendered and not validly
     withdrawn pursuant to the Exchange Offer or the Private Exchange;

          (ii)   deliver to the Pass Through Trustee for cancellation all
     Certificates so accepted for exchange; and

          (iii)  cause the Pass Through Trustee to authenticate and deliver
     promptly to each Holder of Certificates, Exchange Certificates or Private
     Exchange Certificates, as the case may be, equal in principal amount to the
     Certificates of such Holder so accepted for exchange.

          The Exchange Offer and the Private Exchange shall not be subject to
any conditions, other than that (i) the Exchange Offer or the Private Exchange,
as the case may be, does not violate applicable law, rule, regulation or any
applicable interpretation of the Staff, (ii) no action or proceeding is
instituted or threatened in any court or by any governmental agency which might
materially impair the ability of the Company or the Trust to proceed with the
Exchange Offer or the Private Exchange and no material adverse development has
occurred in any existing action or proceeding with respect to the Company or the
Trust and (iii) all U.S. governmental approvals have been obtained, which
approvals the Company deems necessary for the consummation of the Exchange Offer
or Private Exchange.

          The Exchange Certificates and the Private Exchange Certificates may be
issued under (i) the Trust Agreement or (ii) a trust agreement identical in all
material respects to the Trust Agreement, which in either event shall provide
that the Exchange Certificates shall not be subject to the transfer restrictions
set forth in the Trust Agreement.  The Trust Agreement or such trust agreement
shall provide that the Exchange Certificates, the Private Exchange Certificates
and the Certificates shall vote and consent together on all matters as one class
and that neither the Exchange Certificates, the Private Exchange Certificates or
the Certificates will have the right to vote or consent as a separate class on
any matter.

          (c)  If, (i) because of any change in law, rule, regulation or in
currently prevailing interpretations of the Staff, the Company is not permitted
to effect an Exchange Offer, (ii) the Exchange Offer is not consummated within
240 days of the Issue Date, (iii) any holder of Private Exchange Certificates so
requests within 210 days after the consummation of the Private Exchange, or (iv)
in the case of any Holder that

                                      -9-
<PAGE>
 
participates in the Exchange Offer, such Holder does not receive Exchange
Certificates on the date of the exchange that may be sold without restriction
under state and federal securities laws (other than due solely to the status of
such Holder as an affiliate of the Company or the Trust within the meaning of
the Securities Act) and so notifies the Company within 60 days after such Holder
first becomes aware of any such restriction and provides the Company with a
reasonable basis for its conclusion, in the case of each of clauses (i), (ii),
(iii) and (iv) of this sentence, then the Company shall promptly deliver to the
Holders of Registrable Certificates and the Pass Through Trustee written notice
thereof (the "Shelf Notice") and shall use its best efforts to file a Shelf
              ------------                                                 
Registration Statement pursuant to Section 3 hereof.

          3.  Shelf Registration.  If a Shelf Notice is delivered as
              ------------------                                    
contemplated by Section 2(c) hereof, then:

          (a)  Shelf Registration.  The Company, together with the Trust, shall,
               ------------------                                               
at the Company's expense, file with the SEC a Registration Statement for an
offering to be made on a continuous basis pursuant to Rule 415 covering all of
the Registrable Certificates (the "Shelf Registration Statement").  If the
                                   ----------------------------           
Company shall not have filed an Exchange Offer Registration Statement, the
Company shall use its best efforts to file with the SEC the Shelf Registration
Statement as promptly as practicable, but no later than the Filing Date.  The
Shelf Registration Statement shall be on Form F-1 or another appropriate form
permitting registration of such Registrable Certificates for resale by Holders
in the manner or manners designated by them (including, without limitation, one
or more underwritten offerings).  The Company shall not permit any securities
other than the Registrable Certificates to be included in the Shelf Registration
Statement or any Subsequent Shelf Registration Statement.

          The Company shall use its best efforts to cause the initial Shelf
Registration Statement to be declared effective by the SEC under the Securities
Act on or prior to the Effectiveness Date after the delivery of the Shelf Notice
and to keep the Shelf Registration Statement continuously effective under the
Securities Act until the second anniversary of its effective date, subject to
extension pursuant to the last paragraph of Section 5 hereof (the "Effectiveness
                                                                   -------------
Period"), or such shorter period ending when (i) all Registrable Certificates
- ------                                                                       
covered by the Shelf Registration Statement have been sold in the manner set
forth and as contemplated in the initial Shelf Registration Statement or (ii) a
Subsequent Shelf Registration Statement covering all of the Registrable
Certificates has been declared effective by the SEC under the Securities Act;
provided, however, that the Effectiveness Period in respect of the initial Shelf
Registration Statement shall be extended to the extent required to permit
dealers to comply with the applicable prospectus delivery requirement of Rule
174 under the Securities Act and as otherwise provided herein.

                                      -10-

          (b)  Subsequent Shelf Registrations.  If the initial Shelf 
               ------------------------------   
Registration Statement or any Subsequent Shelf Registration Statement ceases to
be effective for any reason at any time during the Effectiveness Period (other
than because of the sale of all of the Registrable Certificates registered
thereunder), the Company shall use its best efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof, and in any event
shall within 30 days of such cessation of effectiveness amend the Shelf
Registration Statement in a manner to obtain the withdrawal of the order
suspending the effectiveness thereof, or file an additional "shelf" Registration
Statement pursuant to Rule 415 covering all of the Registrable Certificates (a
"Subsequent Shelf Registration Statement").  If a Subsequent Shelf Registration 
 ---------------------------------------
Statement is filed, the Company shall use its best efforts to cause the
Subsequent Shelf Registration to be declared effective by the SEC under the
Securities Act as soon as practicable after such filing and to keep such Shelf
Registration Statement continuously effective for a period equal to the number
of days in the Effectiveness Period less the aggregate number of days during
which the Shelf Registration Statement or any Subsequent Shelf Registration was
previously continuously effective. As used herein the term "Shelf Registration
                                                            ------------------ 
Statement" means the Shelf Registration Statement and any Subsequent Shelf
- ---------
Registration Statement.

          (c)  Supplements and Amendments.  The Company shall promptly 
               --------------------------                                 
supplement and amend the Shelf Registration Statement (including any prospectus
contained therein) if required by the rules, regulations or instructions
applicable to the registration form used for such Shelf Registration Statement,
if required by the Securities Act, or if reasonably requested by the Holders of
a majority in aggregate principal amount of the Registrable Certificates covered
by such Shelf Registration Statement or by any underwriter of such Registrable
Certificates.

          4.   Additional Interest.  (a)  The Company and the Initial Purchaser
               -------------------                                             
agree that the Holders of Certificates will suffer damages if either of the
Company or the Trust fails to fulfill its obligations under Section 2 or Section
3 hereof and that it would not be feasible to ascertain the extent of such
damages with precision.  Accordingly, the Company agrees to pay, as liquidated
damages, additional interest on the Notes ("Additional Interest") (which
                                            -------------------         
Additional Interest will be paid by the Company to the Trust and distributed by
the Trust to the Holders of the Certificates) under the circumstances and to
the extent set forth below (each such event referred to in clauses (i) through
(iii) below, a "Registration Default" and each of which shall be given
                --------------------                                  
independent effect):

               (i)  if the Exchange Offer Registration Statement has not been
     filed on or prior to the Filing Date, then commencing on the 151st day
     after the Issue Date, Additional Interest shall accrue on the Notes (and,
     therefore, the

                                      -11-
<PAGE>
 
     Certificates) over and above the accrued interest on the Notes (and
     therefore the Certificates) at a rate of 0.50% per annum for the first 90
     days immediately following such 151st day;

             (ii)   if the Exchange Offer Registration Statement is not declared
     effective by the SEC on or prior to the Effectiveness Date, then commencing
     on the 211th day after the Issue Date, Additional Interest shall accrue on
     the Notes (and, therefore, the Certificates) over and above the accrued
     interest at a rate of 0.50% per annum for the first 90 days immediately
     following such 211th day; and

             (iii)  if (A) the Trust has not exchanged Exchange Certificates for
     all Certificates validly tendered in accordance with the terms of the
     Exchange Offer, (B) the Shelf Registration Statement has not been filed on
     or prior to the Filing Date, (C) the Shelf Registration Statement is not
     declared effective on or prior to the 60th day following the delivery of
     the Shelf Notice or (D) the Shelf Registration Statement or the Exchange
     Offer Registration Statement, as the case may be, has been declared
     effective and ceases to be effective, then Additional Interest shall accrue
     on the Notes (and, therefore, the Certificates) over and above the accrued
     interest at a rate of 0.50% per annum for the first 90 days commencing on
     the day after such Registration Default;

such Additional Interest rate, in the case of each of (i), (ii) and (iii) above,
to increase by an additional 0.50% per annum at the beginning of each subsequent
90-day period; provided, however, that in no event shall the amount of
               --------  -------                                      
Additional Interest exceed 2.00% in the aggregate pursuant to this Section 4;
provided further, that (A) upon the filing of the Exchange Offer Registration
- ----------------                                                             
Statement (in the case of clause (i) of this Section 4(a)), (B) upon the
effectiveness of the Exchange Offer Registration Statement (in the case of
clause (ii) of this Section 4(a)), or (C) upon the exchange of Exchange
Certificates for all Certificates tendered (in the case of clause (iii)(A) of
this Section 4(a)), or upon the filing of a Shelf Registration Statement (in the
case of clause (iii)(B) of this Section 4(a)), or upon the effectiveness of the
Shelf Registration Statement (in the case of clause (iii)(C) of this Section
4(a)), or upon the effectiveness of the Exchange Offer Registration Statement or
the Shelf Registration Statement, as the case may be, which had ceased to remain
effective (in the case of clause (iii)(D) of this Section 4(a)), Additional
Interest on the Notes (and, therefore, the Certificates) as a result of such
clause (or the relevant subclause thereof), as the case may be, shall cease to
accrue until such time as the Shelf Registration Statement, or the Exchange
Offer Registration Statement, as the case may be, shall again cease to remain
effective whereupon the Additional Interest shall resume to accrue in the manner
and for the time periods specified in this Section 4(a).

                                      -12-
<PAGE>
 
          (b)  The Company shall notify the Pass Through Trustee and the
Indenture Trustee of a Registration Default within one business day after any
such Registration Default (an "Event Date").  Any amounts of Additional Interest
                               ----------                                       
due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be payable
in cash semi-annually on each May 1 and November 1 (to the holders of record on
the April 15 and October 15 immediately preceding such dates), commencing with
the first such date occurring after any such Additional Interest commences to
accrue.  The amount of Additional Interest will be determined by multiplying the
applicable rate of Additional Interest by the principal amount of the
Registrable Certificates, multiplied by a fraction, the numerator of which is
the number of days such Additional Interest rate was applicable during such
period (determined on the basis of a 360-day year comprised of twelve 30-day
months and, in the case of a partial month, the actual number of days elapsed),
and the denominator of which is 360.

          5.   Registration Procedures.  In connection with the filing of any
               -----------------------                                       
Registration Statement pursuant to Section 2 or 3 hereof, the Company and the
Trust shall effect such registrations to permit the sale of the securities
covered thereby in accordance with the intended method or methods of disposition
thereof, and pursuant thereto and in connection with any Registration Statement
filed by the Company and the Trust hereunder, the Company and the Trust shall:

          (a)  Prepare and file with the SEC on or prior to the Filing Date, a
     Registration Statement or Registration Statements as prescribed by Section
     2 or 3 hereof, and use its best efforts to cause each such Registration
     Statement to become effective and remain effective as provided herein;
     provided, however, that, if (i) such filing is to be made pursuant to
     --------  -------                                                    
     Section 3 hereof, or (ii) a Prospectus contained in an Exchange Offer
     Registration Statement to be filed pursuant to Section 2 hereof is required
     to be delivered under the Securities Act by any Participating Broker-Dealer
     who seeks to sell Exchange Certificates during the Applicable Period,
     before filing any such Registration Statement or Prospectus or any
     amendments or supplements thereto, the Company shall furnish to counsel
     selected by the Holders of a majority in aggregate principal amount of the
     Registrable Certificates (the "Holders' Counsel"), counsel for such
                                    ----------------                    
     Participating Broker-Dealer and the managing underwriters, if any, and the
     Holders of the Registrable Certificates covered by such Registration
     Statement or each such Participating Broker-Dealer, as the case may be, a
     reasonable opportunity to review copies of all such documents (including
     copies of any documents to be incorporated by reference therein and all
     exhibits thereto) proposed to be filed (in each case at least five business
     days prior to such filing, or such later date as is reasonable under the
     circumstances).  The Company shall not file any Registration Statement or
     Prospectus or any amendments or

                                      -13-
<PAGE>
 
     supplements thereto if the Holders of a majority in aggregate principal
     amount of the Registrable Certificates covered by such Registration
     Statement and the Holders' Counsel, or any such Participating Broker-Dealer
     and its counsel, as the case may be, or the managing underwriters, if any,
     shall reasonably object.

          (b)  Prepare and file with the SEC such amendments and post-effective
     amendments to each Shelf Registration Statement or Exchange Offer 
     Registration Statement, as the case may be, as may be necessary to keep
     such Registration Statement continuously effective for the Effectiveness
     Period or the Applicable Period, as the case may be; cause the related
     Prospectus to be supplemented as required by applicable law, and as so
     supplemented to be filed pursuant to Rule 424 (or any similar provisions
     then in force) promulgated under the Securities Act; and comply with the
     provisions of the Securities Act and the Exchange Act applicable to it with
     respect to the disposition of all securities covered by such Registration
     Statement as so amended or in such Prospectus as so supplemented and with
     respect to the subsequent resale of any securities being sold by a
     Participating Broker-Dealer covered by any such Prospectus. The Company
     shall be deemed not to have used its best efforts to keep a Registration
     Statement effective during the Applicable Period if it voluntarily takes
     any action that would result in selling Holders of the Registrable
     Certificates covered thereby or Participating Broker-Dealers seeking to
     sell Exchange Certificates not being able to sell such Registrable
     Certificates or such Exchange Certificates during that period unless such
     action is required by applicable law.

          (c)  If (i) a Shelf Registration Statement is filed pursuant to
     Section 3 hereof, or (ii) a Prospectus contained in an Exchange Offer
     Registration Statement filed pursuant to Section 2 hereof is required to be
     delivered under the Securities Act by any Participating Broker-Dealer who
     seeks to sell Exchange Certificates during the Applicable Period, notify
     the selling Holders of Registrable Certificates and Holders' Counsel, or
     each such Participating Broker-Dealer and their counsel, as the case may
     be, and the managing underwriters, if any, promptly (but in any event
     within two business days), (i) when a Prospectus or any Prospectus
     supplement or post-effective amendment thereto has been filed, and, with
     respect to a Registration Statement or any post-effective amendment, when
     the same has become effective under the Securities Act (including in such
     notice a written statement that any Holder may, upon request, obtain, at
     the sole expense of the Company, one conformed copy of such Registration
     Statement or post-effective amendment thereto including financial
     statements and schedules, documents incorporated or deemed to be

     stop order suspending the effectiveness of a Registration Statement or of
     any order preventing or suspending the use of any preliminary Prospectus or
     the initiation of any proceedings for that purpose, (iii) if at any time
     when a Prospectus is required by the Securities Act to be delivered in
     connection with sales of the Registrable Certificates or resales of
     Exchange Certificates by Participating Broker-Dealers the representations
     and warranties of the Company contained in any agreement (including any
     underwriting agreement), contemplated by Section 5(n) hereof, to the
     knowledge of the Company, cease to be true and correct in all material
     respects, (iv) of the receipt by the Company of any notification with
     respect to the suspension of the qualification or exemption from
     qualification of a Registration Statement or any of the Registrable
     Certificates or the Exchange Certificates to be sold by any Participating
     Broker-Dealer for offer or sale in any jurisdiction, or the initiation or
     threatening of any proceeding for such purpose, (v) of the happening of any
     event, or any information becoming known that makes any statement made in
     such Registration Statement, or any post-effective amendment thereto,
     Prospectus or any supplement or post-effective amendment thereto, or any
     document incorporated or deemed to be incorporated therein by reference
     untrue in any material respect or that requires the making of any changes
     in or amendments or supplements to such Registration Statement, Prospectus
     or documents so that, in the case of the Registration Statement, it will
     not contain any untrue statement of a material fact or omit to state any
     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, and that in the case of the Prospectus, it will not
     contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading, and (vi) of the Company's determination that a post-
     effective amendment to a Registration Statement would be appropriate.

          (d)  If (i) a Shelf Registration Statement is filed pursuant to
     Section 3 hereof, or (ii) a Prospectus contained in an Exchange Offer
     Registration Statement filed pursuant to Section 2 hereof is required to be
     delivered under the Securities Act by any Participating Broker-Dealer who
     seeks to sell Exchange Certificates during the Applicable Period, use its
     best efforts to prevent the issuance of any order suspending the
     effectiveness of a Registration Statement or of any order preventing or
     suspending the use of a Prospectus or suspending the qualification (or
     exemption from qualification) of any of the Registrable Certificates or the
     Exchange Certificates to be sold by any Participating Broker-Dealer, for
     sale in any jurisdiction, and, if any such order

                                      -15-
<PAGE>
 
     is issued, to use its best efforts to obtain the withdrawal of any such
     order at the earliest possible moment.

          (e)  If a Shelf Registration Statement is filed pursuant to Section 3
     and if requested by the managing underwriter or underwriters (if any), the
     Holders of a majority in aggregate principal amount of the Registrable
     Certificates being sold in connection with an underwritten offering or any
     Participating Broker-Dealer, (i) promptly incorporate in a supplement to
     the Prospectus or post-effective amendment thereto such information as the
     managing underwriter or underwriters (if any), their counsel, such Holders,
     Holders' Counsel, any Participating Broker-Dealer or their counsel
     determine is reasonably necessary to be included therein, (ii) make all
     required filings of such Prospectus supplement or such post-effective
     amendment as soon as practicable after the Company has received
     notification of the matters to be incorporated in such Prospectus
     supplement or post-effective amendment, and (iii) supplement or make
     amendments to such Registration Statement.

          (f)  If (i) a Shelf Registration Statement is filed pursuant to
     Section 3 hereof, or (ii) a Prospectus contained in an Exchange Offer
     Registration Statement filed pursuant to Section 2 hereof is required to be
     delivered under the Securities Act by any Participating Broker-Dealer who
     seeks to sell Exchange Certificates during the Applicable Period, furnish
     to each selling Holder of Registrable Certificates, Holders' Counsel and to
     each such Participating Broker-Dealer who so requests and its counsel and
     each managing underwriter, if any, at the sole expense of the Company, one
     conformed copy of the Registration Statement or Registration Statements and
     each post-effective amendment thereto, including financial statements and
     schedules, and, if requested, all documents incorporated or deemed to be
     incorporated therein by reference and all exhibits.

          (g)  If (i) a Shelf Registration Statement is filed pursuant to
     Section 3 hereof, or (ii) a Prospectus contained in an Exchange Offer
     Registration Statement filed pursuant to Section 2 hereof is required to be
     delivered under the Securities Act by any Participating Broker-Dealer who
     seeks to sell Exchange Certificates during the Applicable Period, deliver
     to each selling Holder of Registrable Certificates and Holders' Counsel, or

     copies of the Prospectus or Prospectuses (including each form of
     preliminary prospectus) and each amendment or supplement thereto and any
     documents incorporated by reference therein as such Persons may reasonably
     request; and, subject to the

                                      -16-
<PAGE>
 
     last paragraph of this Section 5, the Company hereby consents to the use of
     such Prospectus and each amendment or supplement thereto by each of the
     selling Holders of Registrable Certificates or each such Participating
     Broker-Dealer, as the case may be, and the underwriters or agents, if any,
     and dealers (if any), in connection with the offering and sale of the
     Registrable Certificates covered by, or the sale by Participating Broker-
     Dealers of the Exchange Certificates pursuant to, such Prospectus and any
     amendment or supplement thereto.

          (h)  Prior to any public offering of Registrable Certificates or any
     delivery of a Prospectus contained in the Exchange Offer Registration
     Statement by any Participating Broker-Dealer who seeks to sell Exchange
     Certificates during the Applicable Period, use its best efforts to
     cooperate with the selling Holders of Registrable Certificates and Holders'
     Counsel or each such Participating Broker-Dealer and its counsel, as the
     case may be, the managing underwriter or underwriters, if any, and their
     counsel in connection with the registration or qualification (or exemption
     from such registration or qualification) of such Registrable Certificates
     for offer and sale under the securities or Blue Sky laws of such
     jurisdictions within the United States as any selling Holder, Participating
     Broker-Dealer, or the managing underwriter or underwriters reasonably
     request; provided, however, that where Exchange Certificates held by
              --------  -------                                          
     Participating Broker-Dealers or Registrable Certificates are offered other
     than through an underwritten offering, the Company agrees to cause the
     Company's counsel to perform Blue Sky investigations and file registrations
     and qualifications required to be filed pursuant to this Section 5(h); keep
     each such registration or qualification (or exemption therefrom) effective
     during the period such Registration Statement is required to be kept
     effective and do any and all other acts or things reasonably necessary or
     advisable to enable the disposition in such jurisdictions of the Exchange
     Certificates held by Participating Broker-Dealers or the Registrable
     Certificates covered by the applicable Registration Statement; provided,
                                                                    --------
     however, that the Company shall not be required (A) to qualify generally 
     -------  
     to do business in any jurisdiction where it is not then so qualified, (B)
     to take any action that would subject it to general service of process in
     any such jurisdiction where it is not then so subject or (C) to subject
     itself to taxation in excess of a nominal dollar amount in any such
     jurisdiction where it is not then so subject.

          (i)  If a Shelf Registration Statement is filed pursuant to Section 3
     hereof, cooperate with the selling Holders of Registrable Certificates and
     the managing underwriter or underwriters, if any, to facilitate the timely
     preparation and delivery of certificates representing Registrable
     Certificates to be sold, which certificates shall not bear any restrictive
     legends and shall be in a form

                                      -17-
<PAGE>
 
     eligible for deposit with The Depository Trust Company; and enable such
     Registrable Certificates to be in such denominations and registered in such
     names as the managing underwriter or underwriters, if any, or Holders may
     request.

          (j)  Use its best efforts to cause the Registrable Certificates
     covered by the Registration Statement to be registered with or approved by
     such other governmental agencies or authorities as may be reasonably
     necessary to enable the seller or sellers thereof or the underwriter or
     underwriters, if any, to consummate the disposition of such Registrable
     Certificates, except as may be required solely as a consequence of the
     nature of such selling Holder's business, in which case the Company will
     cooperate in all reasonable respects with the filing of such registration
     statement and the granting of such approvals.

          (k)  If (i) a Shelf Registration Statement is filed pursuant to
     Section 3 hereof, or (ii) a Prospectus contained in an Exchange Offer
     Registration Statement filed pursuant to Section 2 hereof is required to be
     delivered under the Securities Act by any Participating Broker-Dealer who
     seeks to sell Exchange Certificates during the Applicable Period, upon the
     occurrence of any event contemplated by paragraph 5(c)(v) or 5(c)(vi)
     hereof, as promptly as practicable prepare and (subject to Section 5(a)
     hereof) file with the SEC, at the sole expense of the Company, a supplement
     or post-effective amendment to the Registration Statement or a supplement
     to the related Prospectus or any document incorporated or deemed to be
     incorporated therein by reference, or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable
     Certificates being sold thereunder or to the purchasers of the Exchange
     Certificates to whom such Prospectus will be delivered by a Participating
     Broker-Dealer, any such Prospectus will 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 light of the
     circumstances under which they were made, not misleading.

          (l)  Use its best efforts to cause the Registrable Certificates
     covered by a Registration Statement or the Exchange Certificates, as the
     case may be, to be rated with the appropriate rating agencies, if so
     requested by the Holders of a majority in aggregate principal amount of
     Registrable Certificates covered by such Registration Statement or the
     Exchange Certificates, as the case may be, or the managing underwriter or
     underwriters, if any.

          (m)  Prior to the effective date of the first Registration Statement
     relating to the Registrable Certificates, (i) provide the Pass Through
     Trustee with

                                      -18-
<PAGE>
 
     certificates for the Registrable Certificates in a form eligible for
     deposit with The Depository Trust Company and (ii) provide a CUSIP number
     for the Registrable Certificates.

          (n)  In connection with any underwritten offering of Registrable
     Certificates pursuant to a Shelf Registration Statement, enter into an
     underwriting agreement as is customary in underwritten offerings of debt
     securities similar to the Registrable Certificates and take all such other
     actions as are reasonably requested by the managing underwriter or
     underwriters in order to expedite or facilitate the registration or the
     disposition of such Registrable Certificates and, in such connection, (i)
     make such representations and warranties to, and covenants with, the
     underwriters with respect to the business of the Company and its
     subsidiaries (including any acquired business, properties or entity, if
     applicable) and the Registration Statement, Prospectus and documents, if
     any, incorporated or deemed to be incorporated by reference therein, in
     each case, as are customarily made by issuers to underwriters in
     underwritten offerings of debt securities similar to the Registrable
     Certificates, and confirm the same in writing if and when requested; (ii)
     use best efforts to obtain the written opinions of counsel to the Company
     and written updates thereof in form, scope and substance reasonably
     satisfactory to the managing underwriter or underwriters, addressed to the
     underwriters covering the matters customarily covered in opinions requested
     in underwritten offerings and such other matters as may be reasonably
     requested by the managing underwriter or underwriters; (iii) use best
     efforts to obtain "cold comfort" letters and updates thereof in form, scope
     and substance reasonably satisfactory to the managing underwriter or
     underwriters from the independent certified public accountants of the
     Company (and, if necessary, any other independent certified public
     accountants of any subsidiary of the Company or of any business acquired by
     the Company for which financial statements and financial data are, or are
     required to be, included or incorporated by reference in the Registration
     Statement), addressed to each of the underwriters, such letters to be in
     customary form and covering matters of the type customarily covered in
     "cold comfort" letters in connection with underwritten offerings and such
      ------------                                                            
     other matters as reasonably requested by the managing underwriter or
     underwriters as permitted by the Statement on Auditing Standards No. 72;
     and (iv) if an underwriting agreement is entered into, the same shall
     contain indemnification provisions and procedures no less favorable than
     those set forth in Section 7 hereof (or such other provisions and
     procedures acceptable to Holders of a majority in aggregate principal
     amount of Registrable Certificates covered by such Registration Statement
     and the managing underwriter or underwriters or agents) with respect to all
     parties to be indemnified pursuant to said Section.

                                      -19-
<PAGE>
 
     The above shall be done at each closing under such underwriting agreement,
     or as and to the extent required thereunder.

          (o) If (i) a Shelf Registration Statement is filed pursuant to Section
     3 hereof, or (ii) a Prospectus contained in an Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Certificates during the Applicable Period, make available for
     inspection by any selling Holder of such Registrable Certificates being
     sold, or each such Participating Broker-Dealer, as the case may be, any
     underwriter participating in any such disposition of Registrable
     Certificates, if any, and any attorney, accountant or other agent retained
     by any such selling Holder or each such Participating Broker-Dealer, as the
     case may be, or underwriter (collectively, the "Inspectors"), at the
                                                     ----------          
     offices where normally kept, during reasonable business hours, all
     financial and other records, pertinent corporate documents and instruments
     of the Company and each of its subsidiaries (collectively, the "Records")
                                                                     -------  
     as shall be reasonably necessary to enable them to exercise any applicable
     due diligence responsibilities, and cause the officers, directors and
     employees of the Company and its subsidiaries to supply all information 
     reasonably requested by any such Inspector in connection with such
     Registration Statement; provided, however, that all information shall be
                             --------  -------                               
     kept confidential by each such Inspector, except to the extent that (i) the
     disclosure of such Records is necessary to avoid or correct a misstatement
     or omission in such Registration Statement, (ii) the release of such
     Records is ordered pursuant to a subpoena or other order from a court of
     competent jurisdiction, (iii) disclosure of such information is, in the
     opinion of counsel for any Inspector, necessary or advisable in connection
     with any action, claim, suit or proceeding, directly or indirectly,
     involving or potentially involving such Inspector and arising out of, based
     upon, relating to, or involving this Agreement, or any transactions
     contemplated hereby or arising hereunder; provided, however, that prior
                                               --------  -------            
     notice be provided as soon as practicable to the Company of the potential
     disclosure of any information by such Inspector pursuant to clause (ii) or
     this clause (iii) to permit the Company to obtain a protective order (or
     waive the provisions of this paragraph (o)) and that such Inspector shall
     take such actions as are reasonably necessary to protect the
     confidentiality of such information (if practicable) to the extent such
     action is otherwise not inconsistent with, an impairment of or in
     derogation of the rights and interests of the Holders or any Inspector, or
     (iv) the information in such Records otherwise has been made generally
     available to the public. Each selling Holder of such Registrable Securities
     and each such Participating Broker-Dealer will be required to agree that
     information obtained by it as a result of such inspections shall be deemed

                                      -20-
<PAGE>
 
     confidential and shall not be used by it as the basis for any market
     transactions in the securities of the Issuer unless and until such
     information is generally available to the public.  Each selling Holder of
     such Registrable Certificates and each such Participating Broker-Dealer
     will be required to further agree that it will, upon learning that
     disclosure of such Records is sought in a court of competent jurisdiction,
     give notice to the Company and allow the Company to undertake appropriate
     action to prevent disclosure of the Records deemed confidential at the
     Company's sole expense.

          (p) Provide a pass through trustee for the Registrable Certificates or
     the Exchange Certificates, as the case may be.

          (q) Cause the Indenture for the Notes to be qualified under the TIA
     not later than the effective date of the Exchange Offer or the first
     Registration Statement relating to the Registrable Certificates; and in
     connection therewith, cooperate with the Indenture Trustee under the
     Indenture and the Holders of the Registrable Certificates, 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 execute, and use its
     best efforts to cause the Indenture Trustee to execute, all documents as
     may be required to effect such changes, and all other forms and documents
     required to be filed with the SEC to enable the Indenture to be so
     qualified in a timely manner.

          (r) Comply with all applicable rules and regulations of the SEC and
     make generally available to its securityholders earnings statements
     satisfying the provisions of Section 11(a) of the Securities Act and Rule
     158 thereunder (or any similar rule promulgated under the Securities Act)
     no later than 45 days after the end of any 12-month period (or 90 days
     after the end of any 12-month period if such period is a fiscal year) (i)
     commencing at the end of any fiscal quarter in which Registrable
     Certificates are sold to underwriters in a firm commitment or best efforts
     underwritten offering and (ii) if not sold to underwriters in such an
     offering, commencing on the first day of the first fiscal quarter of the
     Company after the effective date of a Registration Statement, which
     statements shall cover said 12-month periods.

          (s) Upon consummation of an Exchange Offer or a Private Exchange,
     obtain an opinion of counsel to the Company, in a form customary for under
     written transactions, addressed to the Pass Through Trustee for the benefit
     of all Holders of Registrable Certificates participating in the Exchange
     Offer or the Private Exchange, as the case may be, that the Exchange
     Certificates or Private Exchange Certificates, as the case may be, and the
     related trust agreement

                                      -21-
<PAGE>
 
     constitute legal, valid and binding obligations of the Trust, enforceable
     against the Trust in accordance with their respective terms, subject to
     customary exceptions and qualifications.

          (t) Upon consummation of an Exchange Offer or Private Exchange, obtain
     an opinion of counsel to the Company, addressed to the Pass Through Trustee
     for the benefit of all Holders of Registrable Certificates participating in
     the Exchange Offer or a Private Exchange, as the case may be, that the
     Trust is not an "investment company" as such term is defined in the
     Investment Company Act of 1940, as amended, and the rules and registrations
     thereunder.

          (u) If an Exchange Offer or a Private Exchange is to be consummated 
     upon delivery of the Registrable Certificates by Holders to the Company (or
     to such other Person as directed by the Company) in exchange for the
     Exchange Certificates or the Private Exchange Certificates, as the case may
     be, the Company shall mark, or cause to be marked, on such Registrable
     Certificates that such Registrable Certificates are being cancelled in
     exchange for the Exchange Certificates or the Private Exchange
     Certificates, as the case may be; in no event shall such Registrable
     Certificates be marked as paid or otherwise satisfied.

          (v) Cooperate with each seller of Registrable Certificates covered by
     any Registration Statement, Holders' Counsel and each underwriter, if any,
     participating in the disposition of such Registrable Certificates and its
     counsel in connection with any filings required to be made with the
     National Association of Securities Dealers, Inc. (the "NASD").
                                                            ----   

          (w) Use its best efforts to take all other steps necessary or
     advisable to effect the registration of the Exchange Certificates and/or
     Registrable Certificates covered by a Registration Statement contemplated
     hereby.

          The Company may require each seller of Registrable Certificates as to
which any registration is being effected to furnish to the Company such
information regarding such seller and the distribution of such Registrable
Certificates as the Company may, from time to time, reasonably request.  The
Company may exclude from such registration the Registrable Certificates of any
seller who fails to furnish such information within a reasonable time after
receiving such request.  Each seller as to which any registration pursuant to a
Shelf Registration Statement is being effected agrees to furnish promptly to the
Company all information required to be disclosed in order to make the
information previously furnished to the Company by such seller not materially
misleading.

                                      -22-
<PAGE>
 
          Each Holder of Registrable Certificates and each Participating Broker-
Dealer agrees by acquisition of such Registrable Certificates or Exchange
Certificates to be sold by such Participating Broker-Dealer, as case may be,
that, upon actual receipt of any notice from the Company of the happening of any
event of the kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi)
hereof, such Holder will forthwith discontinue disposition of such Registrable
Certificates covered by such Registration Statement or Prospectus or Exchange
Certificates to be sold by such Holder or Participating Broker-Dealer, as the
case may be, until such Holder's or Participating Broker-Dealer's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section 5(k)
hereof, or until it is advised in writing (the "Advice") by the Company that the
                                                ------                          
use of the applicable Prospectus may be resumed, and has received copies of any
amendments or supplements thereto and, if so directed by the Company, such
Holder or Participating Broker-Dealer, as the case may be, will deliver to the
Company all copies, other than permanent file copies, then in such Holder's or
Participating Broker-Dealer's possession, of the Prospectus covering such
Registrable Securities current at the time of receipt of such notice.  In the
event the Company shall give any such notice, each of the Effectiveness Period
and the Applicable Period shall be extended by the number of days during such
periods from and including the date of the giving of such notice to and
including the date when each seller of Registrable Certificates covered by such
Registration Statement or Exchange Certificates to be sold by such Participating
Broker-Dealer, as the case may be, shall have received (x) the copies of the
supplemented or amended Prospectus contemplated by Section 5(k) hereof or (y)
the Advice.

managing underwriter or underwriters, if any, by the Holders of a majority in

Certificates to be sold by any Participating Broker-Dealer during the Applicable

limitation, the expenses of any special audit and "cold comfort" letters
                                                   ------------         
required by or incident to such performance), (vi) rating agency fees, (vii)
Securities Act liability insurance, if the Company desires such insurance,
(viii) fees and expenses of all other Persons retained by the Company, (ix)
internal expenses of the Company (including, without limitation, all salaries

expenses incurred in connection with the listing of the securities to be
registered on any securities exchange, if applicable, (xii) the expenses
relating to printing, word processing and distributing all Registration
Statements, underwriting agreements, securities sales agreements, indentures and
any other documents necessary in order to comply with this Agreement and (xiii)
fees and expenses of the Pass Through Trustee, Indenture Trustee, and the
Exchange Agent.

          (b) The Company shall reimburse the Holders of the Registrable
Certificates being registered in a Shelf Registration Statement for the
reasonable fees and disbursements of Holders' counsel (in addition to
appropriate local counsel) and other out-of-pocket expenses of such Holders of
Registrable Certificates incurred in connection with the registration and sale
of the Registrable Certificates.

          7.  Indemnification.  (a)  The Company agrees to indemnify and hold
              ---------------                                                
harmless each Holder of Registrable Certificates and each Participating Broker-
Dealer selling Exchange Certificates during the Applicable Period, the officers
and directors of each such Person, and each Person, if any, who controls any
such Person within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act (each, a "Participant"), from and against any and
                                         -----------                            
all losses, claims, damages and liabilities (including, without limitation, and
subject to Section 7(c) below, the reasonable legal fees and other expenses
actually incurred in connection with any suit, action or proceeding or any claim
asserted) caused by, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement (or any amendment thereto) or Prospectus (as amended or supplemented
if the Company shall have furnished any amendments or supplements thereto) or
any pre-

                                      -24-
<PAGE>
 
liminary Prospectus, or caused by, arising out of or based upon any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in the case of the Prospectus in
the light of the circumstances under which they were made, not misleading,
except insofar as such losses, claims, damages or liabilities are caused by any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with information relating to any Participant
furnished to the Company in writing by such Participant expressly for use
therein; provided, however, that the Company shall not be required to indemnify
         --------  -------                                                     
any such Person if such untrue statement or omission or alleged untrue statement
or omission was contained or made in any preliminary prospectus and corrected in
the Prospectus or any amendment or supplement thereto and the Prospectus does
not contain any other untrue statement or omission or alleged untrue statement
or omission of a material fact that was the subject matter of the related
proceeding and any such loss, liability, claim, damage or expense suffered or
incurred by the Participants resulted from any action, claim or suit by any
Person who purchased Registrable Certificates or Exchange Certificates which are
the subject thereof from such Participant and it is established in the related
proceeding that such Participant failed to deliver or provide a copy of the
Prospectus (as amended or supplemented) to such Person with or prior to the
confirmation of the sale of such Registrable Certificates or Exchange
Certificates sold to such Person if required by applicable law, unless such
failure to deliver or provide a copy of the Prospectus (as amended or
supplemented) was a result of noncompliance by the Company with Section 5 of
this Agreement.  Any amounts advanced to an Indemnified Person (as hereafter
defined) pursuant to this Section 7 shall be promptly refunded if it shall be
finally determined that such Indemnified Person was not entitled to such
indemnification.

          (b)  Each Participant agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement and each Person who controls the Company within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to each Participant,
but only with reference to information relating to such Participant furnished to
the Company in writing by such Participant expressly for use in any Registration
Statement or Prospectus, any amendment or supplement thereto, or any preliminary
prospectus. The liability of any Participant under this paragraph shall in no
event exceed the proceeds received by such Participant from sales of Registrable
Certificates or Exchange Certificates giving rise to such obligations.

          (c)  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to either of the
two preceding

                                      -25-
<PAGE>
 
paragraphs, such Person (the "Indemnified Person") shall promptly notify the
                              ------------------                            
Person against whom such indemnity may be sought (the "Indemnifying Person") in
                                                       -------------------     
writing, and the Indemnifying Person, upon request of the Indemnified Person,
shall retain counsel reasonably satisfactory to the Indemnified Person to
represent the Indemnified Person and any others the Indemnified Person may
reasonably designate in such proceeding and shall pay the reasonable fees and
expenses actually incurred by such counsel related to such proceeding; provided,
                                                                       -------- 
however, that the failure to so notify the Indemnifying Person shall not relieve
- -------                                                                         
it of any obligation or liability which it may have hereunder or otherwise
unless and only to the extent that it is directly and materially prejudiced by
such failure and the Company was not otherwise aware of such action or claim).
In any such proceeding, any Indemnified Person shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually agreed in writing to the contrary, (ii)
the Indemnifying Person shall have failed within a reasonable period of time to
retain counsel reasonably satisfactory to the Indemnified Person or (iii) the
named parties in any such proceeding (including any impleaded parties) include
both the Indemnifying Person and the Indemnified Person or any affiliate and
representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them.  It is understood that,
unless there exists a conflict among Indemnified Persons, the Indemnifying
Person shall not, in connection with any one such proceeding or separate but
substantially similar related proceeding in the same jurisdiction arising out of
the same general allegations, be liable for the fees and expenses of more than
one separate firm (in addition to any appropriate local counsel) for all
Indemnified Persons, and that all such fees and expenses shall be reimbursed
promptly after receipt of the invoice therefor as they are incurred.  Any such
separate firm for the Participants and such control Persons of Participants
shall be designated in writing by Participants who sold a majority in interest
of Registrable Certificates and Exchange Certificates sold by all such
Participants and any such separate firm for the Company, its directors, its
officers and such control Persons of the Company shall be designated in writing
by the Company.  The Indemnifying Person shall not be liable for any settlement
of any proceeding effected without its prior written consent (which consent
shall not be unreasonably withheld), but if settled with such consent or if
there be a final judgment for the plaintiff for which the Indemnified Person is
entitled to indemnification pursuant to this Agreement, the Indemnifying Person
agrees to indemnify and hold harmless each Indemnified Person from and against
any loss or liability by reason of such settlement or judgment.  Notwithstanding
the foregoing sentence, if at any time an Indemnified Person shall have
requested an Indemnifying Person to reimburse the Indemnified Person for
reasonable fees and expenses actually incurred by counsel as contemplated by the
second sentence of this paragraph, the Indemnifying Person agrees that it shall
be liable for any settlement of any proceeding effected without its prior
written consent

                                      -26-
<PAGE>
 
if (i) such settlement is entered into more than 30 days after receipt by such
Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person
shall not have reimbursed the Indemnified Person in accordance with such request
prior to the date of such settlement; provided, however, that the Indemnifying
                                      --------  -------                       
Person shall not be liable for any settlement effected without its consent
pursuant to this sentence if the Indemnifying Person is contesting, in good
faith, the request for reimbursement.  No Indemnifying Person shall, without the
prior written consent of the Indemnified Persons (which consent shall not be
unreasonably withheld), effect any settlement or compromise of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party, or indemnity could have been sought hereunder by such
Indemnified Person, unless such settlement or compromise (A) includes an
unconditional written release of such Indemnified Person, in form and substance
reasonably satisfactory to such Indemnified Person, from all liability on claims
that are the subject matter of such proceeding and (B) does not include any
statement as to an admission of fault, culpability or failure to act by or on
behalf of any Indemnified Person.

          (d)  If the indemnification provided for in the first and second
paragraphs of this Section 7 is for any reason unavailable to (other than by
reason of exceptions provided therein), or insufficient to hold harmless, an
Indemnified Person in respect of any losses, claims, damages or liabilities
referred to therein, then each Indemnifying Person under such paragraphs, in
lieu of indemnifying such Indemnified Person thereunder and in order to provide
for just and equitable contribution, shall contribute to the amount paid or
payable by such Indemnified Person as a result of such losses, claims, damages
or liabilities in such proportion as is appropriate to reflect (i) the relative
benefits received by the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other from the offering of the
Certificates or (ii) if the allocation provided by the foregoing clause (i) is
not permitted by applicable law, not only such relative benefits but also the
relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof) as well as any
other relevant equitable considerations.  The relative benefits received by the
Company on the one hand and the Participants on the other shall be deemed to be
in the same proportion as the total proceeds from the offering (net of discounts
and commissions but before deducting expenses) of the Certificates received by
the Company bears to the total proceeds received by such Participant from the
sale of Registrable Certificates or Exchange Certificates, as the case may be.
The relative fault of the parties shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or such

                                      -27-
<PAGE>
 
Participant or such other Indemnified Person, as the case may be, on the other,
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission, and any other equitable
considerations appropriate in the circumstances.

          (e)  The parties 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 Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any reasonable
legal or other expenses actually incurred by such Indemnified Person in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall a
Participant be required to contribute any amount in excess of the amount by
which proceeds received by such Participant from sales of Registrable
Certificates or Exchange Certificates, as the case may be, exceeds the amount of
any damages that such Participant has otherwise been required to pay or has paid
by reason of 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 Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

          (f)  The indemnity and contribution agreements contained in this
Section 7 will be in addition to any liability which the Indemnifying Persons
may otherwise have to the Indemnified Persons referred to above.

          8.   Rules 144 and 144A.  The Company covenants that it will file the
               ------------------                                              
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the SEC thereunder in a timely manner
in accordance with the requirements of the Securities Act and the Exchange Act
and, if at any time the Company is not required to file such reports, it will,
upon the request of Holders of a majority in aggregate principal amount of
Registrable Certificates, make publicly available annual reports and such
information, documents and other reports of the type specified in Sections 13
and 15(d) of the Exchange Act.  The Company further covenants, for so long as
any Registrable Certificates remain outstanding, to make available to any Holder
or beneficial owner of Registrable Certificates in connection with any sale
thereof and any prospective purchaser of such Registrable Certificates from such
Holder or beneficial owner, the information required by Rule 144A(d)(4)

                                      -28-
<PAGE>
 
under the Securities Act in order to permit resales of such Registrable
Certificates pursuant to Rule 144A.


          9.   Underwritten Registrations.  If any of the Registrable
               --------------------------                            
Certificates covered by any Shelf Registration Statement 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 Holders of a
majority in aggregate principal amount of such Registrable Certificates included
in such offering and reasonably acceptable to the Company.


          No Holder of Registrable Certificates may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Certificates 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.


          10.  Miscellaneous.
               ------------- 


          (a)  No Inconsistent Agreements.  The Company has not, as of the date
               --------------------------                                      
hereof, and the Company shall not after the date of this Agreement, enter into
any agreement with respect to any of its securities that is inconsistent with
the rights granted to the Holders of Registrable Certificates 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.  The Company has not entered and will not
enter into any agreement with respect to any of its securities which will grant
to any Person piggy-back registration rights with respect to a Registration
Statement.


          (b)  Adjustments Affecting Registrable Certificates.  The Company
               ----------------------------------------------              
shall not, directly or indirectly, take any action with respect to the
Registrable Certificates as a class that would adversely affect the ability of
the Holders of Registrable Certificates to include such Registrable Certificates
in a registration undertaken pursuant to this Agreement.


          (c)  Amendments and Waivers.  The provisions of this Agreement may not
               ----------------------                                           
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of (A) the Holders of not less than a majority in aggregate principal
amount of the then outstanding Registrable Certificates and (B) in circumstances
that would adversely affect

                                      -29-
<PAGE>
 
the Participating Broker-Dealers, the Participating Broker-Dealers holding not
less than a majority in aggregate principal amount of the Exchange Certificates
held by all Participating Broker-Dealers; provided, however, that Section 7 and
                                          --------  -------                    
this Section 10(c) may not be amended, modified or supplemented without the
prior written consent of each Holder and each Participating Broker-Dealer
(including any person who was a Holder or Participating Broker-Dealer of
Registrable Certificates or Exchange Certificates, as the case may be, disposed
of pursuant to any Registration Statement).  Notwithstanding the foregoing, a
waiver or consent to depart from the provisions hereof with respect to a matter
that relates exclusively to the rights of Holders of Registrable Certificates
whose securities are being sold pursuant to a Registration Statement and that
does not directly or indirectly affect, impair, limit or compromise the rights
of other Holders of Registrable Certificates may be given by Holders of at least
a majority in aggregate principal amount of the Registrable Certificates being
sold by such Holders pursuant to such Registration Statement.


          (d)  Notices.  All notices and other communications provided for or
               -------

Registrable Certificates.


          (f)  Counterparts.  This Agreement may be executed in any number of

               --------

this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,

effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such

hereto irrevocably agrees that any legal dispute, action or proceeding arising
out of or based upon this Agreement may be instituted in any New York State or
U.S. Federal court sitting in the Borough of Manhattan, New York City, New York,
U.S.A. (each a "New York Court" and collectively, the "New York Courts"),
irrevocably waives, to the extent permitted by applicable law, any objection
which it may now or hereafter have to the laying of venue to any such proceeding
and irrevocably submits to the non-exclusive jurisdiction of such courts in any
such suit, action or proceeding.  The Company has appointed CT Corporation
Systems, Inc., 1633 Broadway, New York, New York 10019, as its authorized agent
("Authorized Agent") to receive on its behalf service of copies of the summons
and complaints and any other process which may be served in any legal suit,
action or proceeding arising out of or relating to this Agreement which may be
instituted in any federal or state court sitting in The City of New York,
expressly consents to the jurisdiction of any such court in respect of any such
action, and waives any other requirements of or objections to personal
jurisdiction with respect thereto.  Such appointments shall be irrevocable for a
period of three years from the date of this Agreement.  Such service may be made
by delivering a copy of such process to the Company in care of the Authorized
Agent at the address specified above for the Authorized Agent and obtaining a
receipt therefor, and the Company

                                      -33-
<PAGE>
 
hereby irrevocably authorizes and directs such Authorized Agent to accept such
service on its behalf.  The Company represents and warrants that the Authorized
Agent has agreed to act as said agent for service of process, and agrees that
service of process in such manner upon the Authorized Agent shall be deemed in
every respect effective service of process upon the Company in any such suit,
action or proceeding.  The Company further agrees to take any and all actions as
may be necessary to maintain such designation and appointment of such Authorized
Agent in full force and effect.  If the Authorized Agent shall cease to act as
the Company's agent in The City of New York for service of process, the Company
shall appoint without delay another such agent and notify the Escrow Agent of
such appointment.


          (o)  To the extent that the Company or any of its revenues, assets or
properties shall be entitled, with respect to any proceeding at any time brought
against the Company or any of its revenues, assets or properties or with respect
to any suit, action or proceeding at any time brought for the purpose of
enforcing or executing any judgment in any jurisdiction in which any specified
court or other court is located, to any immunity from suit, from the
jurisdiction of any such court, from attachment prior to judgment, from
attachment in aid of execution of judgment, from execution of a judgment or from
any other legal or judicial process or remedy, and to the extent of such
immunity, the Company irrevocably agrees not to claim and irrevocably waives
such immunity to the fullest extent permitted by the laws of such jurisdiction
(including without limitation, the Foreign Sovereign Immunities Act of 1976 of
the United States).

construed as creating any liability on the part of Wilmington Trust Company,

herein, all such liability, if any, being expressly waived by the parties hereto
and by any Person claiming by, through or under such parties and (d) under no
circumstances shall Wilmington Trust Company be personally liable for the

           specified and clauses contained in this paragraph shall (except where
           otherwise expressed in said paragraph) be nowise limited or
           restricted by reference to or inference from the terms of any other
           clause of this or any other paragraph in this charter, but that the
           objects, purposes and powers specified in each of the clauses of this
           paragraph shall be regarded as independent objects, purposes and

      by resolution or resolutions adopted prior to the issuance of any shares
      of a particular series of Preferred Stock, the voting powers and the
      designations, preferences and relative, optional and other special rights,
      and the qualifications, limitations and restrictions of such series,
      including, but without limiting the generality of the foregoing, the

           Preferred Stock which shall constitute such series, which number may
           be increased (except where otherwise provided by the Board of
           Directors) or decreased (but not below the number of shares thereof
           then outstanding) from time to time by like action of the Board of
           Directors;

           (2)  The rate and times at which, and the terms and conditions on
           which, dividends, if any, on Preferred Stock of such series shall be

           dividends to the dividends payable on any other class or classes, or
           series of the same or other class of

                                       5

           class or classes of stock of the Corporation and the terms and
           conditions of such conversion or exchange;

           (4)  Whether or not Preferred Stock of such series shall be subject
           to redemption, and the redemption price or prices and the time or
           times at which, and the terms and conditions on which, Preferred
           Stock of such series may be redeemed.

           (5)  The rights, if any, of the holders of Preferred Stock of such
           series upon the voluntary or involuntary liquidation, merger,
           consolidation, distribution or sale of assets, dissolution or
           winding-up, of the Corporation.

           (6)  The terms of the sinking fund or redemption or purchase account,
           if any, to be provided for the Preferred Stock of such series; and

           (7)  The voting powers, if any, of the holders of such series of
           Preferred Stock which may, without limiting the generality of the
           foregoing include the right, voting as a series or by itself or
           together with other series of Preferred Stock or all series of
           Preferred Stock as a class, to elect one or more directors of the
           Corporation if there shall have been a default in the payment of
           dividends on any one or more series of Preferred Stock or under such
           circumstances and on such conditions as the Board of Directors may
           determine.

      (c)  (1)  After the requirements with respect to preferential dividends on
      the Preferred Stock (fixed in accordance with the provisions of section
      (b) of this Article FOURTH), if any, shall have been met and after the
      Corporation shall have complied with all the requirements, if any, with

      purchase accounts (fixed in accordance with the provisions of section (b)
      of this Article FOURTH), and subject further to any conditions which may
      be fixed in accordance with the provisions of section (b) of this Article
      FOURTH, then and not otherwise the holders of Common Stock shall be
      entitled to receive such dividends as may be declared from time to time by
      the Board of Directors.

           (2)  After distribution in full of the preferential amount, if any,
           (fixed in accordance with the provisions of section (b) of this
           Article FOURTH), to be distributed to the holders of Preferred Stock
           in the event of voluntary or involuntary liquidation, distribution or
           sale of assets, dissolution or winding-up, of the Corporation, the
           holders of the Common Stock shall be entitled to

                                       6

           receive all of the remaining assets of the Corporation, tangible and
           intangible, of whatever kind available for distribution to
           stockholders ratably in proportion to the number of shares of Common
           Stock held by them respectively.

           (3)  Except as may otherwise be required by law or by the provisions
           of such resolution or resolutions as may be adopted by the Board of
           Directors pursuant to section (b) of this Article FOURTH, each holder
           of Common Stock shall have one vote in respect of each share of
           Common Stock held on all matters voted upon by the stockholders.

      (d)  No holder of any of the shares of any class or series of stock or of
      options, warrants or other rights to purchase shares of any class or
      series of stock or of other securities of the Corporation shall have any
      preemptive right to purchase or subscribe for any unissued stock of any
      class or series or any additional shares of any class or series to be
      issued by reason of any increase of the authorized capital stock of the
      Corporation of any class or series, or bonds, certificates of
      indebtedness, debentures or other securities convertible into or
      exchangeable for stock of the Corporation of any class or series, or
      carrying any right to purchase stock of any class or series, but any such
      unissued stock, additional authorized issue of shares of any class or
      series of stock or securities convertible into or exchangeable for stock,
      or carrying any right to purchase stock, may be issued and disposed of
      pursuant to resolution of the Board of Directors to such persons, firms,

      resolutions adopted pursuant to authority granted in section (b) of this
      Article FOURTH and the consent, by class or series vote or otherwise, of
      the holders of such of the series of Preferred Stock as are from time to
      time outstanding shall not be required for the issuance by the Board of
      Directors of any other series of Preferred Stock whether or not the
      powers, preferences and rights of such other series shall be fixed by the
      Board of Directors as senior to, or on a parity with, the powers,
      preferences and rights of such outstanding series, or any of them;
      provided, however, that the Board of Directors may provide in the
      resolution or resolutions as to any series of Preferred Stock adopted
      pursuant to section (b) of this Article FOURTH that the consent of the
      holders of a majority (or such greater proportion as shall be therein
      fixed) of the outstanding shares of such series voting thereon shall be
      required for the issuance of any or all other series of Preferred Stock.

<PAGE>
 
      (f)  Subject to the provisions of section (e), shares of any series of
      Preferred Stock may be issued from time to time as the Board of Directors
      of the Corporation shall determine and on such terms and for such
      consideration as shall be fixed by the Board of Directors.

      (g)  Shares of Common Stock may be issued from time to time as the Board
      of Directors of the Corporation shall determine and on such terms and for
      such consideration as shall be fixed by the Board of Directors.

      (h)  The authorized amount of shares of Common Stock and of Preferred
      Stock may, without a class or series vote, be increased or decreased from
      time to time by the affirmative vote of the holders of a majority of the
      stock of the Corporation entitled to vote thereon.

      FIFTH: - (a)  The business and affairs of the Corporation shall be
      conducted and managed by a Board of Directors.  The number of directors
      constituting the entire Board shall be not less than five nor more than
      twenty-five as fixed from time to time by vote of a majority of the whole
      Board, provided, however, that the number of directors shall not be
      reduced so as to shorten the term of any director at the time in office,
      and provided further, that the number of directors constituting the whole
      Board shall be twenty-four until otherwise fixed by a majority of the
      whole Board.

      (b)  The Board of Directors shall be divided into three classes, as nearly
      equal in number as the then total number of directors constituting the
      whole Board permits, with the term of office of one class expiring each
      year.  At the annual meeting of stockholders in 1982, directors of the
      first class shall be elected to hold office for a term expiring at the
      next succeeding annual meeting, directors of the second class shall be
      elected to hold office for a term expiring at the second succeeding annual
      meeting and directors of the third class shall be elected to hold office
      for a term expiring at the third succeeding annual meeting.  Any vacancies
      in the Board of Directors for any reason, and any newly created
      directorships resulting from any increase in the directors, may be filled
      by the Board of Directors, acting by a majority of the directors then in
      office, although less than a quorum, and any directors so chosen shall
      hold office until the next annual election of directors.  At such
      election, the stockholders shall elect a successor to such director to
      hold office until the next election of the class for which such director
      shall have been chosen and until his successor shall be elected and
      qualified.  No decrease in the number of directors shall shorten the term
      of any incumbent director.

      (c)  Notwithstanding any other provisions of this Charter or Act of
      Incorporation or the By-Laws of the Corporation (and notwithstanding the
      fact that some lesser percentage may be specified by law, this Charter or
      Act of Incorporation or the By-Laws of the Corporation), any director or
      the entire Board of Directors of the

                                       8

      affirmative vote of the holders of two-thirds or more of the outstanding
      shares of capital stock of the Corporation entitled to vote generally in
      the election of directors (considered for this purpose as one class) cast
      at a meeting of the stockholders called for that purpose.

      (d)  Nominations for the election of directors may be made by the Board of
      Directors or by any stockholder entitled to vote for the election of
      directors.  Such nominations shall be made by notice in writing, delivered
      or mailed by first class United States mail, postage prepaid, to the
      Secretary of the Corporation not less than 14 days nor more than 50 days
      prior to any meeting of the stockholders called for the election of
      directors; provided, however, that if less than 21 days' notice of the
      meeting is given to stockholders, such written notice shall be delivered
      or mailed, as prescribed, to the Secretary of the Corporation not later
      than the close of the seventh day following the day on which notice of the
      meeting was mailed to stockholders.  Notice of nominations which are
      proposed by the Board of Directors shall be given by the Chairman on
      behalf of the Board.

      (e)  Each notice under subsection (d) shall set forth (i) the name, age,
      business address and, if known, residence address of each nominee proposed
      in such notice, (ii) the principal occupation or employment of such
      nominee and (iii) the number of shares of stock of the Corporation which
      are beneficially owned by each such nominee.

      (f)  The Chairman of the meeting may, if the facts warrant, determine and
      declare to the meeting that a nomination was not made in accordance with
      the foregoing procedure, and if he should so determine, he shall so
      declare to the meeting and the defective nomination shall be disregarded.

      (g)  No action required to be taken or which may be taken at any annual or
      special meeting of stockholders of the Corporation may be taken without a
      meeting, and the power of stockholders to consent in writing, without a
      meeting, to the taking of any action is specifically denied.

      SIXTH: - The Directors shall choose such officers, agent and servants as
      may be provided in the By-Laws as they may from time to time find
      necessary or proper.

      however, that any such additional By-Laws, alterations or repeal may be
      adopted only by the affirmative vote of the holders of two-thirds or more
      of the outstanding shares of capital stock of the Corporation entitled to
      vote generally in the election of directors (considered for this purpose
      as one class).

hereafter be amended, any person who was or is made or is threatened to be made

under this Article X is not paid in full within ninety days after a written

part, shall be entitled to be paid the expense of prosecuting such claim. In any
such action the Corporation shall have the burden of proving that the claimant

these By-Laws, agreement, vote of stockholders or disinterested Directors or
otherwise.

PERSON TO PARTICIPATE IN A DISTRIBUTION (WITHIN THE MEANING OF THE SECURITIES
ACT) OF EXCHANGE CERTIFICATES TO BE RECEIVED IN THE EXCHANGE OFFER, AND (IV) IF
THE UNDERSIGNED IS NOT A BROKER-DEALER, THE UNDERSIGNED IS NOT ENGAGED IN, AND
DOES NOT INTEND TO ENGAGE IN, A DISTRIBUTION (WITHIN THE MEANING OF THE
SECURITIES ACT) OF SUCH EXCHANGE CERTIFICATES.  BY TENDERING ORIGINAL
CERTIFICATES PURSUANT TO THE EXCHANGE OFFER AND EXECUTING THIS LETTER OF
TRANSMITTAL, AN ORIGINAL CERTIFICATEHOLDER WHICH IS A BROKER-DEALER REPRESENTS
AND AGREES, CONSISTENT WITH CERTAIN INTERPRETIVE LETTERS ISSUED BY THE STAFF OF
THE DIVISION OF CORPORATION FINANCE OF THE SECURITIES AND EXCHANGE COMMISSION TO
THIRD PARTIES, THAT (A) SUCH ORIGINAL CERTIFICATES HELD BY THE BROKER-DEALER ARE
HELD ONLY AS A NOMINEE, OR (B) SUCH ORIGINAL CERTIFICATES WERE ACQUIRED BY SUCH
BROKER-DEALER FOR ITS OWN ACCOUNT AS A RESULT OF MARKET-MAKING ACTIVITIES OR
OTHER TRADING ACTIVITIES AND IT WILL DELIVER A PROSPECTUS (AS AMENDED OR
SUPPLEMENTED FROM TIME TO TIME) MEETING THE REQUIREMENTS OF THE SECURITIES ACT
IN CONNECTION WITH ANY RESALE OF SUCH EXCHANGE CERTIFICATES (PROVIDED THAT, BY
SO ACKNOWLEDGING AND BY DELIVERING A PROSPECTUS, SUCH BROKER-DEALER WILL NOT BE
DEEMED TO ADMIT THAT IT IS AN "UNDERWRITER" WITHIN THE MEANING OF THE SECURITIES
ACT).

     THE COMPANY AND THE TRUST HAVE AGREED THAT, SUBJECT TO THE PROVISIONS OF
THE REGISTRATION RIGHTS AGREEMENT, THE PROSPECTUS, AS IT MAY BE AMENDED OR
SUPPLEMENTED FROM TIME TO TIME, MAY BE USED BY A PARTICIPATING BROKER-DEALER (AS
DEFINED BELOW) IN CONNECTION WITH RESALES OF EXCHANGE CERTIFICATES RECEIVED IN
EXCHANGE FOR ORIGINAL CERTIFICATES, WHERE SUCH ORIGINAL CERTIFICATES WERE
ACQUIRED BY SUCH PARTICIPATING BROKER-DEALER FOR ITS OWN ACCOUNT AS A RESULT OF
MARKET-MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES, FOR A PERIOD ENDING 90
DAYS AFTER THE EXPIRATION DATE (SUBJECT TO EXTENSION UNDER CERTAIN LIMITED
CIRCUMSTANCES DESCRIBED IN THE PROSPECTUS) OR, IF EARLIER, WHEN ALL SUCH
EXCHANGE CERTIFICATES HAVE BEEN DISPOSED OF BY SUCH PARTICIPATING BROKER-DEALER.
IN THAT REGARD, EACH BROKER-DEALER WHO ACQUIRED ORIGINAL CERTIFICATES FOR ITS
OWN ACCOUNT AS A RESULT OF MARKET-MAKING OR OTHER TRADING ACTIVITIES (A
"PARTICIPATING BROKER-DEALER"), BY TENDERING SUCH ORIGINAL CERTIFICATES AND
EXECUTING THIS LETTER OF TRANSMITTAL OR DELIVERING AN AGENT'S MESSAGE IN LIEU
THEREOF, AGREES THAT, UPON RECEIPT OF NOTICE FROM THE COMPANY OR THE TRUST OF
THE OCCURRENCE OF ANY EVENT OR THE DISCOVERY OF ANY FACT WHICH MAKES ANY
STATEMENT CONTAINED OR INCORPORATED BY REFERENCE IN THE PROSPECTUS UNTRUE IN ANY
MATERIAL RESPECT OR WHICH CAUSES THE PROSPECTUS TO OMIT TO STATE A MATERIAL FACT
NECESSARY IN ORDER TO MAKE THE STATEMENTS CONTAINED OR INCORPORATED BY REFERENCE
THEREIN, IN LIGHT OF THE CIRCUMSTANCES UNDER WHICH THEY WERE MADE, NOT
MISLEADING OR OF THE OCCURRENCE OF CERTAIN OTHER EVENTS SPECIFIED IN THE
REGISTRATION RIGHTS AGREEMENT, SUCH PARTICIPATING BROKER-DEALER WILL SUSPEND THE
SALE OF EXCHANGE CERTIFICATES PURSUANT TO THE PROSPECTUS UNTIL THE COMPANY OR
THE TRUST HAS AMENDED OR SUPPLEMENTED THE PROSPECTUS TO CORRECT SUCH
MISSTATEMENT OR OMISSION AND HAS FURNISHED COPIES OF THE AMENDED OR SUPPLEMENTED
PROSPECTUS TO THE PARTICIPATING 

                                       5
<PAGE>
 
BROKER-DEALER OR THE COMPANY OR THE TRUST HAS GIVEN NOTICE THAT THE SALE OF THE
EXCHANGE CERTIFICATES MAY BE RESUMED, AS THE CASE MAY BE. IF THE COMPANY OR THE
TRUST GIVES SUCH NOTICE TO SUSPEND THE SALE OF THE EXCHANGE CERTIFICATES, IT
SHALL EXTEND THE 90-DAY PERIOD REFERRED TO ABOVE DURING WHICH PARTICIPATING
BROKER-DEALERS ARE ENTITLED TO USE THE PROSPECTUS IN CONNECTION WITH THE RESALE
OF EXCHANGE CERTIFICATES BY THE NUMBER OF DAYS DURING THE PERIOD FROM AND
INCLUDING THE DATE OF THE GIVING OF SUCH NOTICE TO AND INCLUDING THE DATE WHEN
PARTICIPATING BROKER-DEALERS SHALL HAVE RECEIVED COPIES OF THE SUPPLEMENTED OR
AMENDED PROSPECTUS NECESSARY TO PERMIT RESALES OF THE EXCHANGE CERTIFICATES OR
TO AND INCLUDING THE DATE ON WHICH THE COMPANY OR THE TRUST HAS GIVEN NOTICE
THAT THE SALE OF EXCHANGE CERTIFICATES MAY BE RESUMED, AS THE CASE MAY BE.

     As a result, a Participating Broker-Dealer who intends to use the
Prospectus in connection with resales of Exchange Certificates received in
exchange for Original Certificates pursuant to the Exchange Offer must notify
the Company or the Trust, or cause the Company or the Trust to be notified, on
or prior to the Expiration Date, that it is a Participating Broker-Dealer.  Such
notice may be given in the space provided above or may be delivered to the
Exchange Agent at the address set forth in the Prospectus under "The Exchange
Offer--Exchange Agent."

     The Original Certificateholders whose Original Certificates are accepted
for exchange will not receive Distributions on such Original Certificates after
May 1, 1998 and the undersigned waives the right to receive any Distribution on
such Original Certificates accumulated from May 1, 1998.  Accordingly, holders
of Exchange Certificates ("Exchange Certificateholders") as of the record date
for the payment of Distributions on November 1, 1998 will be entitled to
Distributions accumulated from May 1, 1998.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Trust or the Exchange Agent to be necessary or desirable
to complete the exchange, sale, assignment and transfer of the Original
Certificates tendered hereby.  All authority herein conferred or agreed to be

        FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
                                                                       
      1. DELIVERY OF LETTER OF TRANSMITTAL AND ORIGINAL CERTIFICATES; GUARANTEED
DELIVERY PROCEDURES. This Letter of Transmittal is to be completed either if (a)
tenders are to be made pursuant to the procedures for tender by book-entry
transfer set forth in "The Exchange Offer--Procedures for Tendering Original
Certificates" in the Prospectus and an Agent's Message is not delivered or
Original Certificates are to be forwarded herewith. Timely confirmation of a
book-entry transfer of such Original Certificates into the Exchange Agent's
account at DTC (a "book-entry confirmation"), as well as this Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees, and any other documents required by this
Letter of Transmittal, must be received by the Exchange Agent at its addresses
set forth herein on or prior to the Expiration Date. Tenders by book-entry
transfer may also be made by delivering an Agent's Message in lieu of this
Letter of Transmittal. The term "Agent's Message" means a message, transmitted
by DTC to and received by the Exchange Agent and forming a part of a book-entry
confirmation, which states that DTC has received an express acknowledgment from
the DTC participant, which acknowledgment states that such participant has
received and agrees to be bound by the Letter of Transmittal (including the
representations contained herein) and that the Trust and the Company may enforce
the Letter of Transmittal against such participant. Original Certificates may be
tendered in whole or in part in principal amount of not less than $250,000 and
integral multiples of $1,000 in excess thereof; provided that, if any Original
                                                --------
Certificates are tendered for exchange in part, the untendered thereof must be
$250,000 or any integral multiple of $1,000 in excess thereof.

     Original Certificateholders who wish to tender their Original Certificates
and (i) who cannot complete the procedures for delivery by book-entry transfer
on a timely basis, (ii) who cannot deliver their Original Certificates, this
Letter of Transmittal and all other required documents to the Exchange Agent on
or prior to the Expiration Date or (iii) whose Original Certificates are not
immediately available may tender their Original Certificates by properly
completing and duly executing a Notice of Guaranteed Delivery pursuant to the
guaranteed delivery procedures set forth in "The Exchange Offer--Procedures for
Tendering Original Certificates" in the Prospectus.  Pursuant to such
procedures: (a) such tender must be made by or through an Eligible Institution
(as defined below); (b) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form accompanying this Letter of
Transmittal, must be received by the Exchange Agent on or prior to the
Expiration Date; and (c) the Original Certificates (or a book-entry
confirmation) representing tendered Original Certificates, in proper form for
transfer, together with a Letter of Transmittal (or facsimile thereof or Agent's
Message in lieu thereof), properly completed and duly executed, with any
required signature guarantees and any other documents required by this Letter of
Transmittal, must be received by the Exchange Agent within three New York Stock
Exchange trading days after the date of execution of such Notice of Guaranteed
Delivery, all as provided in "The Exchange Offer--Procedures for Tendering
Original Certificates" in the Prospectus.

     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by facsimile or mail to the Exchange Agent, and must include a guarantee by an
Eligible Institution in the form set forth in such Notice.  For Original
Certificates to be properly tendered pursuant to the guaranteed delivery
procedure, the Exchange Agent must receive a Notice of Guaranteed Delivery on or
prior to the Expiration Date.  As used herein and in the Prospectus, "Eligible
Institution" means a firm or other entity identified in Rule 17Ad-15 under the
Exchange Act as "an eligible guarantor institution," including (as such terms
are defined therein) (i) a bank; (ii) a broker, dealer, municipal securities
broker or dealer or government securities broker or dealer; (iii) a credit
union; (iv) a national securities exchange, registered securities association or
clearing agency; or (v) a savings association that is a participant in a
Securities Transfer Association.

THE METHOD OF DELIVERY OF ORIGINAL CERTIFICATES, THIS LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
ORIGINAL CERTIFICATEHOLDER AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN
ACTUALLY RECEIVED BY THE EXCHANGE AGENT.  IF DELIVERY IS BY MAIL, REGISTERED
MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, OR OVERNIGHT DELIVERY
SERVICE IS RECOMMENDED.  IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.

     Neither the Company nor the Trust will accept any alternative, conditional
or contingent tenders.  Each tendering holder, by execution of a Letter of
Transmittal (or facsimile thereof), waives any right to receive any notice of
the acceptance of such tender.

                                       9
<PAGE>
 
     2.  GUARANTEE OF SIGNATURES.  No signature guarantee on this Letter of
Transmittal is required if:

     (i)  this Letter of Transmittal is signed by the registered holder (which
term, for purposes of this document, shall include any participant in DTC whose
name appears on a security position listing as the owner of the Original
Certificates) of Original Certificates tendered herewith, unless such holder(s)
has completed either the box entitled "Special Issuance Instructions" or the box
entitled "Special Delivery Instructions" above, or

     (ii)  such Original Certificates are tendered for the account of a firm
that is an Eligible Institution.

     In all other cases, an Eligible Institution must guarantee the signature(s)
on this Letter of Transmittal.  See Instruction 5.

     3. INADEQUATE SPACE. If the space provided in the box captioned
"Description of Original Certificates" is inadequate, the Certificate number(s)
of Original Certificates and any other required information should be listed on
a separate signed schedule which is attached to this Letter of Transmittal.

     4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS. Tenders of Original Certificates
will be accepted only in the amount of $250,000 and integral multiples of $1,000
in excess thereof, provided that if any Original Certificates are tendered for
                   --------
exchange in part, the untendered thereof must be $250,000 or any integral
multiple of $1,000 in excess thereof. All Original Certificates delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.

     Except as otherwise provided herein, tenders of Original Certificates may
be withdrawn at any time on or prior to the Expiration Date.  In order for a
withdrawal to be effective on or prior to that time, a written, telegraphic,
telex or facsimile transmission of such notice of withdrawal must be timely
received by the Exchange Agent at one of its addresses set forth above or in the
Prospectus on or prior to the Expiration Date.  Any such notice of withdrawal
must specify the name of the person who tendered the Original Certificates to be
withdrawn, the aggregate amount of Original Certificates to be withdrawn, and
(if Certificates for Original Certificates have been tendered) the name of the
registered Original Certificates as set forth on the Original Certificates, if
different from that of the person who tendered such Original Certificates.  If
Certificates for the Original Certificates have been delivered or otherwise
identified to the Exchange Agent, then prior to the physical release of the
Original Certificates, the tendering holder must submit the serial numbers shown
on the particular Original Certificates to be withdrawn and the signature on the
notice of withdrawal must be guaranteed by an Eligible Institution, except in
the case of Original Certificates tendered for the account of an Eligible
Institution.  If Original Certificates have been tendered pursuant to the
procedures for book-entry transfer set forth in "The Exchange Offer--Procedures
for Tendering Original Certificates," the notice of withdrawal must specify the
name and number of the account at DTC to be credited with the withdrawal of
Original Certificates, in which case a notice of withdrawal will be effective if
delivered to the Exchange Agent by written, telegraphic, telex or facsimile
transmission on or prior to the Expiration Date.  Withdrawals of tenders of
Original Certificates may not be rescinded.  Original Certificates properly
withdrawn will not be deemed validly tendered for purposes of the Exchange
Offer, but may be retendered at any subsequent time on or prior to the
Expiration Date by following any of the procedures described in the Prospectus
under "The Exchange Offer--Procedures for Tendering Original Certificates."

     All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Trust, in its sole
discretion, whose determination shall be final and binding on all parties.
Neither the Company, the Trust, any affiliates or assigns of the Company or the
Trust, the Exchange Agent nor any other person shall be under any duty to give
any notification of any irregularities in any notice of withdrawal or incur any
liability for failure to give any such notification.  Any Original Certificates
which have been tendered but which are withdrawn will be returned to the holder
thereof without cost to such holder promptly after withdrawal.

     5.  SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Original
Certificates tendered hereby, the signature(s) must correspond exactly with the
name(s) as written on the face of the Certificate(s) without alteration,
enlargement or any change whatsoever.

     If any of the Original Certificates tendered hereby are owned of record by
two or more joint owners, all such owners must sign this Letter of Transmittal.

                                       10
<PAGE>
 
     If any tendered Original Certificates are registered in different name(s)
on several certificates, it will be necessary to complete, sign and submit as
many separate Letters of Transmittal (or facsimiles thereof) as there are
different registrations of certificates.

     If this Letter of Transmittal or any Original Certificates or bond powers
are signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of Companies or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing and must submit proper
evidence satisfactory to the Company and the Trust, in their sole discretion, of
such persons' authority to so act.

     When this Letter of Transmittal is signed by the registered owner(s) of the
Original Certificates listed and transmitted hereby, no endorsement(s) of
Certificate(s) or separate bond power(s) are required unless Exchange
Certificates are to be issued in the name of a person other than the registered
Original Certificateholder(s).  Signature(s) on such Original Certificate(s) or
bond power(s) must be guaranteed by an Eligible Institution.

     If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Original Certificates listed, the Original
Certificates must be endorsed or accompanied by appropriate bond powers, signed
exactly as the name or names of the registered owner(s) appear(s) on the
certificates, and also must be accompanied by such opinions of counsel,
certifications and other information as the Trust or the Exchange Agent may
require in accordance with the restrictions on transfer applicable to the
Original Certificates.  Signatures on such Original Certificates or bond powers
must be guaranteed by an Eligible Institution.

     6.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If Exchange Certificates
are to be issued in the name of a person other than the signer of this Letter of
Transmittal, or if Exchange Certificates are to be sent to someone other than
the signer of this Letter of Transmittal or to an address other than that shown
above, the appropriate boxes on this Letter of Transmittal should be completed.
Original Certificates not exchanged will be returned by mail or, if tendered by
book-entry transfer, by crediting the account indicated above maintained at DTC
unless the appropriate boxes on this Letter of Transmittal are completed. See
Instruction 4.

     7.  IRREGULARITIES. The Company and the Trust will determine, in their sole
discretion, all questions as to the form of documents, validity, eligibility
(including time of receipt) and acceptance for exchange of any tender of
Original Certificates, which determination shall be final and binding on all
parties. The Company and the Trust reserve the absolute right, in their sole and
absolute discretion, to reject any and all tenders determined by them not to be
in proper form or the acceptance of which, or exchange for, may, in the view of
counsel to the Company and the Trust, be unlawful. The Company and the Trust
also reserve the absolute right, subject to applicable law, to waive any of the
conditions of the Exchange Offer set forth in the Prospectus under "The Exchange
Offer--Conditions to the Exchange Offer" or any conditions or irregularity in
any tender of Original Certificates of any particular holder whether or not
similar conditions or irregularities are waived in the case of other holders.
The Company's and the Trust's interpretation of the terms and conditions of the
Exchange Offer (including this Letter of Transmittal and the instructions
hereto) will be final and binding. No tender of Original Certificates will be
deemed to have been validly made until all irregularities with respect to such
tender have been cured or waived. Neither the Company, the Trust, any affiliates
or assigns of the Company, the Trust, the Exchange Agent, nor any other person
shall be under any duty to give notification of any irregularities in tenders or
incur any liability for failure to give such notification.

     8.  QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions and
requests for assistance may be directed to the Exchange Agent at its address and
telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, this Letter of Transmittal and the Notice
of Guaranteed Delivery may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.

     9.  WAIVER OF CONDITIONS. The Company and the Trust reserve the absolute
right, subject to applicable law, to waive satisfaction of any or all conditions
enumerated in the Prospectus.

     10.  NO CONDITIONAL TENDERS. No alternative, conditional or contingent
tenders will be accepted. All tendering holders of Original Certificates, by
execution of this Letter of Transmittal, shall waive any right to receive notice
of the acceptance of Original Certificates for exchange.

     Neither the Company, the Trust, the Exchange Agent nor any other person is
obligated to give notice of any defect or irregularity with respect to any
tender of Original Certificates nor shall any of them incur any liability for
failure to give any such notice.

                                       11
<PAGE>
 
     11.  LOST, DESTROYED OR STOLEN ORIGINAL CERTIFICATES.  If any Original
Certificates have been lost, destroyed or stolen, the holder should promptly
notify the Exchange Agent.  The holder will then be instructed as to the steps
that must be taken in order to replace the Original Certificate(s).  This Letter
of Transmittal and related documents cannot be processed until the procedures
for replacing lost, destroyed or stolen Original Certificate(s) have been
followed.

     12.  SECURITY TRANSFER TAXES. Holders who tender their Original
Certificates for exchange will not be obligated to pay any transfer taxes in
connection therewith. If, however, Exchange Certificates are to be delivered to,
or are to be issued in the name of, any person other than the registered
Original Certificateholder tendered, or if a transfer tax is imposed for any
reason other than the exchange of Original Certificates in connection with the
Exchange Offer, then the amount of any such transfer tax (whether imposed on the
registered 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 with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.

     IMPORTANT:  THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF) AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO THE
EXPIRATION DATE.

Marine Midland Bank
140 Broadway, 12th Floor
New York, New York 10005

Ladies and Gentlemen:


     Transtel Pass Through Trust, a statutory business trust formed under the
laws of the State of Delaware (the "Trust"), proposes to make an offer (the
"Exchange Offer") to exchange all outstanding 12 1/2% Pass Through Trust
Certificates due 2007, representing interests in 12 1/2% Senior Notes due 2007
issued by Transtel S.A. (the "Company") (the "Original Certificates") for 
12 1/2% Pass Through Exchange Certificates due 2007, representing interests in
12 1/2% Senior Notes due 2007 issued by the Company (the "Exchange
Certificates"), which have been registered under the Securities Act of 1933, as
amended (the "Securities Act"). The terms and conditions of the Exchange Offer
as currently contemplated are set forth in a prospectus, dated           , 1998 
(the "Prospectus"), proposed to be distributed to all record holders of the
Original Certificates. The Original Certificates and the Exchange Certificates
are collectively referred to herein as the "Certificates." Capitalized terms
used herein and not otherwise defined shall have the meanings assigned to them
in the Prospectus.

     The Trust hereby appoints Marine Midland Bank to act as exchange agent (the
"Exchange Agent") in connection with the Exchange Offer.  References hereinafter
to "you" shall refer to Marine Midland Bank.

     The Exchange Offer is expected to be commenced by the Trust on or about
, 1998. The Letter of Transmittal accompanying the Prospectus is to be used by
the holders of the Original Certificates (the "Original Certificateholders") to
accept the Exchange Offer and contains certain instructions with respect to (i)
the delivery of certificates for Original Certificates tendered in connection
therewith and (ii) the book entry transfer of Certificates to the Exchange
Agent's account at The Depository Trust Company ("DTC").
<PAGE>
 
     The Exchange Offer shall expire at 5:00 p.m., New York City time, on
_______________________ , 1998 or on such later date or time to which the 
Trust or the Company may extend the Exchange Offer (the "Expiration Date").
Subject to the terms and conditions set forth in the Prospectus, the Trust and
the Company expressly reserve the right to extend the Exchange Offer from time
to time by giving oral (to be confirmed in writing) or written notice to you no
later than 5:00 p.m., New York City time, on the business day following the
previously scheduled Expiration Date.

     The Trust and the Company expressly reserve the right to amend or terminate
the Exchange Offer, and not to accept for exchange any Original Certificates not
theretofore accepted for exchange, upon the occurrence of any of the conditions
of the Exchange Offer specified in the Prospectus under the caption "The
Exchange Offer -- Conditions to the Exchange Offer."  The Trust or the Company
will give oral (to be confirmed in writing) or written notice of any amendment,
termination or nonacceptance of Original Certificates to you as promptly as
practicable.

     In carrying out your duties as Exchange Agent, you are to act in accordance
with the following instructions:

     1.    You will perform such duties and only such duties as are specifically
set forth in the section of the Prospectus captioned "The Exchange Offer" and as
specifically set forth herein and such duties which are necessarily incidental
thereto; provided, however, that in no way will your general duty to act in good
         --------  -------                                                      
faith be discharged by the foregoing.

     2.   You will establish an account with respect to the Original
Certificates at DTC (the "Book-Entry Transfer Facility") for purposes of the
Exchange Offer within two business days after the date of the Prospectus, and
any financial institution that is a participant in the Book Entry Transfer
Facility's systems may make book-entry delivery of the Original Certificates by
causing the Book-Entry Transfer Facility to transfer such Original Certificates
into your account in accordance with the Book-Entry Transfer Facility's
procedure for such transfer.

     3.  You are to examine each of the Letters of Transmittal, certificates for
Original Certificates (or confirmations of book-entry transfers into your
account at the Book-Entry Transfer Facility) and any Agent's Message or other
documents delivered or mailed to you by or for Original Certificateholders to
ascertain whether: (i) the Letters of Transmittal and any such other documents
are duly executed and properly completed in accordance with instructions set
forth therein and (ii) the Original Certificates have otherwise been properly
tendered. In each case where the Letter of Transmittal or any other document has
been improperly completed or executed or any of the certificates for Original
Certificates are not in proper form for transfer or some other irregularity in
connection with the acceptance of the Exchange Offer exists, you will endeavor
to inform the presenters of the need for fulfillment of all requirements and to
take any other action as may be necessary or advisable to cause such
irregularity to be corrected.

                                       2
<PAGE>
 
     4.   With the approval of the Pass Through Trustee of the Trust or any
person designated in writing by the Company (a "Designated Officer") (such
approval, if given orally, to be confirmed in writing) or any other party
designated by the Pass Through Trustee or Designated Officer in writing, you are
authorized to waive any irregularities in connection with any tender of Original
Certificates pursuant to the Exchange Offer.

     5.   Tenders of Original Certificates may be made only as set forth in
the Letter of Transmittal and in the section of the Prospectus captioned "The
Exchange Offer -- Procedures for Tendering Original Certificates" and Original
Certificates shall be considered properly tendered to you only when tendered in
accordance with the procedures set forth therein.

     Notwithstanding the provisions of this paragraph 5, Original Certificates
which the Pass Through Trustee of the Trust or Designated Officer of the Company
shall approve as having been properly tendered shall be considered to be
properly tendered (such approval, if given orally, shall be confirmed in
writing).

     6.  You shall advise the Trust and the Company with respect to any Original
Certificates delivered subsequent to the Expiration Date and accept their
instructions with respect to disposition of such Original Certificates.

     7.   You shall accept tenders:

  a)    in cases where the Original Certificates are registered in two or
more names only if signed by all named holders;

  b)    in cases where the signing person (as indicated on the Letter of
Transmittal) is acting in a fiduciary or a representative capacity only when
proper evidence of such person's authority to so act is submitted; and

  c)    from persons other than the registered Original Certificateholder 
provided that customary transfer requirements, including payment of any
applicable transfer taxes, are fulfilled.

     You shall accept partial tenders of Original Certificates where so
indicated and as permitted in the Letter of Transmittal and deliver certificates
for Original Certificates to the transfer agent for split-up and return any
untendered Original Certificates to the holder (or to such other person as may
be designated in the Letter of Transmittal) as promptly as practicable after
expiration or termination of the Exchange Offer.

     8.   Upon satisfaction or waiver of all of the conditions to the Exchange
Offer, the Trust will notify you (such notice, if given orally, to be confirmed
in writing) of the Company's and the Trust's acceptance, promptly after the
Expiration Date, of all Original Certificates properly tendered and you, on
behalf of the Trust, will 

                                       3
<PAGE>
 
exchange such Original Certificates for Exchange Certificates and cause such
Original Certificates to be canceled. Delivery of Exchange Certificates will be
made on behalf of the Trust by you in $1,000 denominations; provided, however,
                                                            ------------------
that in all cases, Original Certificates tendered pursuant to the Exchange Offer
will be exchanged only after timely receipt by you of certificates for such
Original Certificates (or confirmation of book-entry transfer into your account
at the Book-Entry Transfer Facility), a properly completed and duly executed
Letter of Transmittal (or facsimile thereof) with any required signature
guarantees (or an Agent's Message in lieu thereof) and any other required
documents. You shall issue Exchange Certificates only in denominations of $1,000
or any integral multiple thereof. Original Certificates may be tendered in whole
or in part in minimum denominations of $250,000 and integral multiples of $1,000
in excess thereof, provided that if any Original Certificates are tendered for
exchange in part, the untendered amount must be $250,000 or any integral
multiple of $1,000 in excess thereof.

     9.   Tenders pursuant to the Exchange Offer are irrevocable, except
that, subject to the terms and upon the conditions set forth in the Prospectus
and the Letter of Transmittal, Original Certificates tendered pursuant to the
Exchange Offer may be withdrawn at any time on or prior to the Expiration Date.

     10.   The Company and the Trust shall not be required to exchange any
Original Certificates tendered if any of the conditions set forth in the
Exchange Offer are not met.  Notice of any decision by the Company and the Trust
not to exchange any Original Certificates tendered shall be given (such notice,
if given orally, shall be confirmed in writing) by the Company or the Trust to
you.

     11.   If, pursuant to the Exchange Offer, the Company or the Trust does
not accept for exchange all or part of the Original Certificates tendered
because of an invalid tender, the occurrence of certain other events set forth
in the Prospectus under the caption "The Exchange Offer -- Conditions to the
Exchange Offer" or otherwise, you shall as soon as practicable after the
expiration or termination of the Exchange Offer return those certificates for
unaccepted Original Certificates (or effect the appropriate book-entry transfer
of the unaccepted Original Certificates), together with any related required
documents and the Letters of Transmittal relating thereto that are in your
possession, to the persons who deposited them.

     12.   All certificates for reissued Original Certificates, unaccepted
Original Certificates or for Exchange Certificates shall be forwarded by (a)
first-class mail under a blanket surety bond protecting you, the Trust and the
Company from loss or liability arising out of the non-receipt or non-delivery of
such certificates or (b) by registered mail insured separately for the
replacement value of each of such certificates.

     13.   You are not authorized to pay or offer to pay any concessions,
commissions or solicitation fees to any broker, dealer, bank or other persons or
to engage or utilize any person to solicit tenders.

     14.   As Exchange Agent hereunder you:

                                       4
<PAGE>
 
  a)   will be regarded as making no representations and having no
responsibilities as to the validity, sufficiency, value or genuineness of any of
the certificates or the Original Certificates represented thereby deposited with
you pursuant to the Exchange Offer, and will not be required to and will make no
representation as to the validity, value or genuineness of the Exchange Offer;
provided, however, that in no way will your general duty to act in good faith be
- --------  -------                                                               
discharged by the foregoing;

  b)   shall not be obligated to take any legal action hereunder which might in
your reasonable judgment involve any expense or liability, unless you shall have
been furnished with reasonable indemnity;

  c)   may rely on and shall be protected in acting in good faith in reliance
upon any certificate, instrument, opinion, notice, letter, facsimile or other
document or security delivered to you and reasonably believed by you to be
genuine and to have been signed by the proper party or parties;

  d)   may act upon any tender, statement, request, agreement or other
instrument whatsoever not only as to its due execution and validity and
effectiveness of its provisions, but also as to the truth and accuracy of any
information contained therein, which you shall in good faith reasonably believe
to be genuine or to have been signed or represented by a proper person or
persons;

  e)   may conclusively rely on and shall be protected in acting upon written or
oral instructions from the Pass Through Trustee of the Trust or from any
Designated Officer of the Company with respect to the Exchange Offer;

  f)   shall not advise any person tendering Original Certificates pursuant to
the Exchange Offer as to the wisdom of making such tender or as to the market
value or decline or appreciation in market value of any Original Certificates;
and

  g)   may consult with your counsel with respect to any questions relating to
your duties and responsibilities, and the written opinion of such counsel shall
be full and complete authorization and protection in respect of any action
taken, suffered or omitted by you hereunder in good faith and in accordance with
such written opinion of such counsel.

     15.   You shall take such action as may from time to time be requested by
the Pass Through Trustee of the Trust, any Designated Officer of the Company, or
Dewey Ballantine LLP, special counsel for the Company and the Trust, (and such
other action as you may reasonably deem appropriate) to furnish copies of the
Prospectus, Letter of Transmittal and the Notice of Guaranteed Delivery, or such
other forms as may be approved from time to time by the Company or the Trust, to
all persons requesting such documents and to accept and comply with telephone
requests for information relating to the Exchange Offer, provided that such
information shall relate only to the procedures for accepting (or withdrawing
from) the Exchange Offer. The Company or the Trust will furnish you with copies
of such documents at your request. All other

                                       5
<PAGE>
 
requests for information relating to the Exchange Offer shall be directed to the
Company, Attention: Guillermo O. Lopez.

     16.   You shall advise by facsimile transmission or telephone, and
promptly thereafter confirm in writing to Guillermo O. Lopez of the Company, and
such other person or persons as the Trust or the Company may request, daily (and
more frequently during the week immediately preceding the Expiration Date and if
otherwise requested) up to and including the Expiration Date, as to the amount
of the Original Certificates which have been tendered pursuant to the Exchange
Offer and the items received by you pursuant to this Agreement, separately
reporting and giving cumulative totals as to items properly received and items
improperly received and items covered by Notices of Guaranteed Delivery.  In
addition, you will also inform, and cooperate in making available to, the
Company and the Trust or any such other person or persons as the Company or the
Trust requests from time to time prior to the Expiration Date of such other
information as they or such person reasonably request.  Such cooperation shall
include, without limitation, the granting by you to the Company, the Trust and
such person as the Company or the Trust may request of access to those persons
on your staff who are responsible for receiving tenders, in order to ensure that
immediately prior to the Expiration Date, the Company and the Trust shall have
received information in sufficient detail to enable them to decide whether to
extend the Exchange Offer.  You shall prepare a list of persons who failed to
tender or whose tenders were not accepted and the aggregate amount of Original
Certificates not tendered or Original Certificates not accepted and deliver said
list to the Company and the Trust at least seven days prior to the Expiration
Date.  You shall also prepare a final list of all persons whose tenders were
accepted, the aggregate amount of Original Certificates tendered and the
aggregate amount of Original Certificates accepted and deliver said list to the
Company.

     17.   Letters of Transmittal and Notices of Guaranteed Delivery shall
be stamped by you as to the date and the time of receipt thereof and shall be
preserved by you for a period of time at least equal to the period of time you
preserve other records pertaining to the transfer of securities.  You shall
dispose of unused Letters of Transmittal and other surplus materials by
returning them to the Company at the address set forth below for notices.

     18.   For services rendered as Exchange Agent hereunder, you shall be
entitled to such compensation and reimbursement of reasonable out-of-pocket
expenses as set forth on Schedule I attached hereto.

     19.   You hereby acknowledge receipt of the Prospectus and the Letter
of Transmittal and further acknowledge that you have examined each of them to
the extent necessary to perform your duties hereunder.  Any inconsistency
between this Agreement, on the one hand, and the Prospectus and the Letter of
Transmittal (as they may be amended from time to time), on the other hand, shall
be resolved in favor of the latter two documents, except with respect to the
duties, liabilities and indemnification of you as Exchange Agent, which shall be
controlled by this Agreement.

                                       6
<PAGE>
 
     20.   (a)  The Company agrees to indemnify and hold you harmless in
your capacity as Exchange Agent hereunder against any liability, cost or
expense, including reasonable attorneys' fees, arising out of or in connection
with any act, omission, delay or refusal made by you in reasonable reliance upon
any signature, endorsement, assignment, certificate, order, request, notice,
instruction or other instrument or document reasonably believed by you to be
valid, genuine and sufficient and in accepting any tender or effecting any
transfer of Original Certificates reasonably believed by you in good faith to be
authorized, and in delaying or refusing in good faith to accept any tenders or
effect any transfer of Original Certificates; provided, however, that the
                                              --------  -------          
Company shall not be liable for indemnification or otherwise for any loss,
liability, cost or expense to the extent arising out of your negligence, willful
misconduct or bad faith.  In no case shall the Company be liable under this
indemnity with respect to any claim against you unless the Company shall be
notified by you, by letter or by facsimile confirmed by letter, of the written
assertion of a claim against you or of any other action commenced against you,
promptly after you shall have received any such written assertion or notice of
commencement of action.  The Company shall be entitled to participate at its own
expense in the defense of any such claim or other action, and, if the Company so
elects, the Company shall assume the defense of any suit brought to enforce any
such claim.  In the event that the Company shall assume the defense of any such
suit, the Company shall not thereafter be liable for the fees and expenses of
any counsel retained by you so long as the Company shall retain counsel
reasonably satisfactory to you to defend such suit; provided that the Company
shall not be entitled to assume the defense of any such suit if the named
parties to such suit include both the Company and you and representation of both
parties by the same legal counsel would, in the written opinion of counsel to
you, be inappropriate due to actual or potential conflicting interests between
them.

           (b) You agree that, without the prior written consent of the Company
(which consent shall not be unreasonably withheld or delayed), you will not
settle, compromise or consent to the entry of judgment in connection with any
pending or threatened claim, action, or proceeding in respect of which
indemnification could be sought in accordance with the indemnification
provisions of this Agreement (whether or not you or the Company or any of its
officers, directors or controlling shareholders is an actual or potential party
to such claim, action or proceeding), unless such settlement, compromise or
consent includes an unconditional release of the Company and its officers,
directors and controlling shareholders from all liability arising out of such
claim, action or proceeding.

     21.   This Agreement and your appointment as Exchange Agent hereunder
shall be construed and enforced in accordance with the laws of the State of New
York applicable to agreements made and to be performed entirely within such
state, and without regard to conflicts of law principles, and shall inure to the
benefit of, and the obligations created hereby shall be binding upon, the
successors and assigns of each of the parties hereto.

                                       7
