         THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION FROM THIS PROSPECTUS. WE
URGE YOU TO READ THE ENTIRE PROSPECTUS CAREFULLY. WE ALSO ENCOURAGE YOU TO
REVIEW THE FINANCIAL STATEMENTS AND OTHER INFORMATION PROVIDED IN REPORTS AND
OTHER DOCUMENTS THAT WE FILE WITH THE SECURITIES AND EXCHANGE COMMISSION, WHICH

                                  OUR BUSINESS

OVERVIEW


         We are a leading full service communications service provider in the
Dominican Republic. We offer local, long distance, mobile, Internet and
broadband data transmission services. Our wireless network covers approximately
85% of the population in the Dominican Republic. Our network providing local
service is 100% digital, the only such network in the Dominican Republic.
Telecommunications networks that employ digital technology can transmit higher
quality signals at lower cost. We also own interests in undersea fiber optic
cable networks that connect and transmit telecommunications signals between
Central America, the Caribbean, the United States and Europe. Fiber optic cable
is composed of glass strands and transmits telecommunications signals in the
form of light. Through our subsidiary, TRICOM USA, Inc., we own
telecommunication switching facilities in New York, Miami and Puerto Rico. Using
these facilities, we originate, transport and terminate international
long-distance traffic. We are one of the few Latin American long distance
carriers that is licensed by the U.S. Federal Communications Commission to use
switching facilities that it operates to connect long distance traffic.



         Since our inception in 1992, we have diversified our operations, and
have captured a significant share in key markets entirely through internal
growth. In 1999, we carried approximately 40% of the southbound voice and data
traffic from the United States to the Dominican Republic. Since we introduced
wireless services in 1995, we have achieved an approximate 40% market share as
of year-end 2000, based upon data published by the Instituto Dominicano de las
Telecomunicaciones, or INDOTEL, the Dominican agency that regulates
telecommunications.



         We were the leader in the Dominican Republic for 1998 and 1999 in net
new customer additions in the market for local service and in 1998 for net new
customer additions for mobile services, based upon data published by INDOTEL.
Our recent success is reflected in the following period-to-period changes in
operating statistics from 1999 to 2000:


         o        Local access lines increased 24.7% to 148,312;
         o        Cellular and PCS subscribers increased 61.9% to 284,991; and
         o        International long distance traffic increased 65.6% to 597.2
                  million minutes.

         We plan to establish in selected Central American markets a mobile
service network targeted at business customers that will provide uninterrupted
connection throughout the region without any change

in service provider or equipment. We will deploy an advanced integrated
radio-telephone and dispatch communications system known as IDEN(R), developed
by Motorola. This technology enables us to use spectrum efficiently and offer
multiple wireless services on one digital handset. We plan to capitalize on the
increasing demand by business customers for a product that provides advanced
mobile services and a complete solution for their intra-regional communication
needs.



         We have purchased a 51% interest in a Panamanian company,
Cellular Communications of Panama, S.A., now TRICOM Panama, S.A., which owns
the frequency rights for 107 channels of 25 MHz each. TRICOM Panama has
approximately 1,600 analog mobile users. These frequencies will give us
access to nationwide coverage, covering a population of approximately 2.81
million people. Currently, we are constructing an iDEN network, at a cost as
of September 30, 2001 of approximately $33 million, in Panama City and Colon,
the two largest cities in Panama, and in important transportation corridors
in other parts of the country. Our expected completion date for this phase of
the buildout is the first quarter of 2002. We will offer digital mobile
integrated services, including two-way radio, paging and interconnect
services.


         In 2000, we were awarded, in a government auction, radio frequency
rights in Guatemala to 172 channels of 25 MHz, providing us with nationwide
coverage. We also have acquired in El Salvador radio frequency rights for an
aggregate of 185 channels of 25 MHz, that provides spectrum to operate our iDEN
network. We currently do not intend to develop a network in either Guatemala or
El Salvador in the remainder of 2001 and 2002.

RECENT DEVELOPMENTS


         On October 26, 2001, we acquired the shares of TCN Dommicana,
S.A., a wholly-owned Subsidairy of Telecable Nacional, C. por A., that owns
and operates the largest multi-channel system in the Dominican Republic's
pay-TV market including the concession granted by the Dominacan government to
operate a cable system. The transaction was valued at approximately $1,130 per
subscriber equivalent or $63.7 million, payable $41.8 million in cash and
with 3,375,000 shares of our Class A common stock.





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

         We are incorporated in the Dominican Republic. Our operations are

         share. This is your basic subscription privilege.


WHAT IS THE RECORD DATE?


         [_______], 2001 at 5:00 p.m., New York City time. Only our shareholders
         as of the record date will receive subscription rights.


WHY IS TRICOM OFFERING THE RIGHTS?


         We are seeking additional equity. GFN, one of our major shareholders,
         has committed to provide to us $40 million in additional equity. Our
         board of directors has chosen to give you the opportunity to buy more
         shares on the same basis as GFN.


HAS THE BOARD OF DIRECTORS MADE A RECOMMENDATION REGARDING THIS OFFERING?


             Our board of directors makes no recommendation to you about whether
you should exercise any rights in this offering.


HOW SOON MUST YOU ACT?


             The rights expire on December [__], 2001 at 5:00 p.m., New York
             City time. The subscription agent must actually receive all
             required documents and payments before that date and time.


MAY I SELL OR GIVE AWAY MY RIGHTS?

             No. The rights may not be sold or otherwise transferred.


WHAT IS THE OVERSUBSCRIPTION PRIVILEGE?



             If you fully exercise your basic subscription privilege, the
             oversubscription privilege entitles you to subscribe for additional
             ADSs at the same subscription price of $___ per share that applies
             to your basic subscription privilege.



WHAT ARE THE LIMITATIONS ON THE OVERSUBSCRIPTION PRIVILEGE?



             We will be able to satisfy your exercise of the oversubscription
             privilege only if our other shareholders receiving rights do not
             elect to purchase all of the shares offered under their basic
             subscription privilege.


AM I REQUIRED TO SUBSCRIBE IN THIS OFFERING?

             No. You are not required to exercise any rights, purchase any new
             shares or otherwise take any action in response to this offering.



                                      -3-
<Page>

WHAT WILL HAPPEN IF I DO NOT EXERCISE MY RIGHTS?


             You will retain your current number of shares even if you do not
             exercise your rights. However, if you do not exercise your rights
             and other shareholders do, the percentage of TRICOM that you own
             will diminish.


MAY I CHANGE OR CANCEL MY EXERCISE OF RIGHTS AFTER I SEND IN THE REQUIRED FORMS?


             No. Once you send in your subscription certificate and payment, you
             cannot revoke the exercise of your rights.





WILL MY MONEY BE RETURNED IF THIS OFFERING IS AMENDED, WITHDRAWN OR TERMINATED?


             If we terminate or cancel this offering, or any submitted
             subscriptions no longer comply with the amended terms of this
             offering, we will promptly return your subscription price, but
             without any payment of interest.


WHAT ARE THE U.S. FEDERAL INCOME AND DOMINICAN TAX CONSEQUENCES OF EXERCISING MY
RIGHTS?


             The receipt and exercise of your rights are intended to be
             nontaxable under U.S. federal and Dominican law.


WHEN WILL I RECEIVE MY NEW SHARES?

             If you purchase ADSs through the rights offering, you will receive
             ADSs representing those shares as soon as practicable after the
             expiration date of the offering.

HOW MUCH MONEY WILL WE RECEIVE FROM THE RIGHTS OFFERING?

             Our gross proceeds from the rights offering depend on the number of
             shares that are purchased. If all rights are exercised, then we
             will receive net proceeds of approximately $105 million in cash,
             including funds previously advanced to us by GFN, one of our major
             shareholders.


HOW WILL WE USE THE PROCEEDS FROM THE RIGHTS OFFERING?


             We will use any proceeds generated from the exercise of rights in
             this rights offering for general corporate purposes, including to
             fund, in part, our acquisition of Telecable and for working
             capital.

HOW MANY SHARES WILL BE OUTSTANDING AFTER THE RIGHTS OFFERING?


             If we sell all of the shares offered by this prospectus, then we
             will issue [_____________] new ADSs, representing the same number
             of shares of Class A




                                      -4-
<Page>


             common stock, and then we will have [_________] shares of Class A
             common stock outstanding, including Shares to be issued to GFN.


WHAT SHOULD I DO IF I WANT TO PARTICIPATE IN THIS OFFERING, BUT MY SHARES ARE
HELD IN THE NAME OF MY BROKER, DEALER OR OTHER NOMINEE?

             If you hold your ADSs through a broker, dealer or other nominee,
             for example, through a custodian bank, then your broker, dealer or
             other nominee is the record holder of the shares you own. This
             record holder must exercise the rights on your behalf for the
             shares you wish to purchase. Therefore, you will need to have your
             record holder act for you.




WHAT FEES OR CHARGES APPLY IF I PURCHASE SHARES?

             We are not charging any fee or sales commission to issue rights to
             you or to issue ADSs to you if you exercise rights. If you exercise
             rights through a record holder of your shares, you are responsible
             for paying any fees that person may charge.

HOW DO I EXERCISE MY RIGHTS? WHAT FORMS AND PAYMENT ARE REQUIRED TO PURCHASE
SHARES?


             As a record holder of our ADSs, on [____________,] 2001, you are
             receiving this prospectus, a subscription certificate evidencing
             your subscription rights and instructions on how to purchase
             shares. If you wish to participate in this offering, then, before
             your rights expire, you must:




             o         deliver the subscription price by certified or cashier's
                       check or bank draft drawn upon a U.S. bank, or a U.S.
                       postal money order, or a personal check that clears
                       before expiration of the rights; and



             o         deliver a properly completed subscription certificate.


TO WHOM SHOULD I SEND FORMS AND PAYMENTS?

             You should send your subscription documents and payment by mail or

         In this prospectus references to "$," "US$" or "U.S. dollars" are to
United States dollars, and references to "Dominican pesos" or "RD$" are to
Dominican pesos. This prospectus contains translations of certain Dominican
pesos amounts into U.S. dollars at specified rates solely for the convenience
of the reader. These translations should not be construed as representations
that the Dominican peso amounts actually represent such U.S. dollar amounts
or could be converted into U.S. dollars at the rate indicated. The average of
prices of one U.S. dollar quoted by certain private commercial banks or the
private market rate, as reported by Banco Central de la Republica Dominicana
on September 28, 2001 was RD$16.83 = US$1.00, the date closest to the date of
the most recent financial information included in this prospectus. The
Federal Reserve Bank of New York does not report a noon buying rate for
Dominican pesos. On November 7, 2001, the private market rate was RD$16.92 =
US$1.00.

(1)      Except per share information, ratios and Other Operating Data.

(2)      Since 1996, we have made payments in lieu of income tax to the
         Dominican government, in accordance with the terms of our concession
         agreement. These payments represent 10% of gross domestic revenues,
         after deducting charges for access to the local network, plus 10% of
         net international revenues. Expense in lieu of income taxes also
         includes a tax, implemented in 1998, of 2% on international settlement
         revenues collected. This tax amounted to $0.3 million in 1998, $0.6
         million in 1999 and $0.4 million in 2000.

(3)      Effective January 1, 2000, we adopted the U.S. Securities and Exchange
         Commission's Staff Accounting Bulletin No. 101, concerning the
         recognition of revenue. This pronouncement provides that we recognize
         net revenues from installations and activations over the period in
         which we retain our clients, which based on our experience is
         approximately 35 months. Since we previously recognized these revenues
         when they were collected, this change in revenue recognition resulted
         in a one-time, non-cash charge to earnings in 2000 of $16,452,799. At
         December 31, 2000, deferred revenues for installations and activations
         aggregated $14,654,886, which will be recognized as follows: $9,010,741
         in 2001; $4,793,662 in 2002; and $850,483 in 2003.

(4)      Includes capital lease obligations incurred during 1999 of $26.2
         million and during 2000 of $17.7 million.


(5)      EBITDA typically consists of earnings (loss) before interest and other
         income and expenses, income taxes and depreciation and amortization. As
         described in note 2 we make payments to the Dominican government in
         lieu of income taxes. As a result, we calculate EBITDA prior to the
         deduction of payments to the Dominican government in lieu of income
         taxes. Our calculation of EBITDA may not be comparable to EBITDA
         calculated by other companies. We believe that EBITDA is useful to
         investors because EBITDA is commonly used in the telecommunications
         industry to analyze companies on the basis of operating performance,
         leverage and liquidity. However, it does not purport to represent cash
         generated or used by operating activities and should not be considered
         in isolation or as a substitute for a measure of performance in
         accordance with generally accepted accounting principles. For 1999 and
         2000, we have also added back to EBITDA amortization of radio frequency
         rights of $198,333 and $320,186, respectively.

                                  RISK FACTORS

         YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW AND OTHER
INFORMATION IN THIS PROSPECTUS AND IN OUR REPORTS INCORPORATED BY REFERENCE INTO
THIS PROSPECTUS BEFORE DECIDING TO PURCHASE SHARES OF THIS OFFERING.


RISKS RELATING TO OUR CAPITAL STRUCTURE

         OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR ABILITY TO FUND
EXPANSION AND OUR COMPETITIVE POSITION.


         We are highly leveraged. At September 30, 2001, we had outstanding
approximately $450.6 million in aggregate principal amount of indebtedness,
including capital leases. At September 30, 2001, we had approximately $241.4
million total shareholders' equity.

         The degree to which we are leveraged could have important consequences
to us, including the following:

         o        a substantial portion of our cash flow must be used to pay
                  interest on our indebtedness. Therefore, our cash flow
                  available for use in our business will be reduced;

         o        our high degree of leverage could increase our vulnerability
                  to changes in general economic conditions;

         o        our ability to obtain additional financing for working
                  capital, capital expenditures, acquisitions, general corporate
                  purposes or other purposes could be impaired;

         o        we are much more leveraged than our principal competitor,
                  which may be a competitive disadvantage in our principal
                  market; and

         o        our failure to comply with covenants and restrictions
                  contained in our notes' indenture could lead to a default
                  which could cause that and other debt to become immediately
                  payable.

         WE MAY NOT BE ABLE TO GENERATE SUFFICIENT CASH FLOW FROM OPERATIONS TO
MEET OUR DEBT SERVICE REQUIREMENTS.


         Our ability to pay interest on our indebtedness and meet our debt
service obligations will depend on our future performance, which in turn
depends on successful implementation of our strategy and on financial,
competitive, regulatory, technical and other factors, many of which are
beyond our control. Our interest expense for the nine months ended September
30, 2001 was $28.5 million and our cash flow from operations for the nine
months ended September 30, 2001 was $20.3 million. Approximately $185.7
million of our indebtedness will mature during the 12 months ending September
30, 2002, however most of these borrowings will be renewed or rolled over at
maturity. Our ability to refinance any of this indebtedness will depend on
our financial condition at the time it matures, the restrictions in the
agreements governing our indebtedness and other factors, including general
market and economic conditions. If refinancing were not possible, we could be
forced to dispose of assets at unfavorable prices. In addition, our inability
to refinance these obligations could result in our defaulting on our other
debt obligations.


         WE DEPEND ON SHORT-TERM BORROWINGS IN THE DOMINICAN FINANCIAL MARKETS,
         WHICH BEAR HIGH INTEREST RATES AND WE CANNOT BE CERTAIN THAT THEY WILL
         CONTINUE TO BE AVAILABLE.


         We fund a substantial portion of our capital expenditure and working
capital requirements with short-term borrowings in the Dominican financial
markets. As of September 30, 2001, we had $96.3 million of these borrowings,
with interest rates ranging from 9.5% to 13% per annum for the U.S. dollar
denominated debt and from 17% to 20% per annum for the RD peso denominated
debt. These borrowings

                                      -10-
<Page>


have maturities ranging up to 180 days and often are payable on demand. However,
our current lenders may be unable or unwilling to lend to us in the future. Even
if these short term borrowings continue to be available to us, due to their
short-term maturities, we may be required to repay them at times when
replacement financing is not available on commercially attractive terms.


RISKS RELATED TO OUR OPERATIONS


         OUR PRINCIPAL COMPETITOR IN THE DOMINICAN REPUBLIC, CODETEL, HAS
         SUBSTANTIALLY GREATER MARKET SHARE AND RESOURCES, WHICH MAY PREVENT US
         FROM MAINTAINING OR INCREASING OUR MARKET SHARE.



         We compete primarily with Compania Dominicana de Telefonos C. por A.,
or Codetel, a wholly owned subsidiary of Verizon Communications Inc. Codetel has
an established market presence, networks and resources substantially greater
than ours. More than 80% of the Dominican Republic's local access line customers
are customers of Codetel. The growth of our market share depends upon our
ability to obtain customers in areas that currently are not served, or are
underserved, by Codetel and to convince Codetel customers to either add, or
switch to, the telephony services we offer. If Codetel implements significant
price reductions for particular services we may be forced to reduce our rates in
response in order to remain competitive. In addition, Codetel could expend
significantly greater amounts of capital than are available to us in order to
upgrade its network and/or sustain price reductions over a prolonged period. As
a result we may not be able to maintain or increase our market share.



         THERE ARE NEW ENTRANTS IN THE DOMINICAN MARKETS, PARTICULARLY FOR
         WIRELESS SERVICES, WHICH COULD INCREASE COMPETITION FOR OUR SERVICES,
         REDUCE OUR MARKET SHARE OR INCREASE PRICE COMPETITION.


         The Dominican government has granted telecommunications concessions to
a number of companies in the last several years.


         o        In 1999, France Telecom S.A. acquired a company which has a
                  concession to provide telecommunication services. France
                  Telecom has used the concession to offer wireless services.
                  France Telecom's marketing efforts has included offering
                  services at discounts.



         o        In January 2000, Centennial Communications Corp. acquired 70%
                  of All America Cables and Radio, Inc., an integrated
                  telecommunications provider. Centennial is attempting to
                  expand All America's share of the Dominican market for
                  cellular and PCS services.



         o        In the international long distance market, investment by U.S.
                  telecommunications companies in Dominican markets could limit
                  the number of U.S. carriers that would send a significant
                  number of minutes to us or otherwise adversely affect our
                  ability to generate international settlement revenue.



         o        As a result of these and other potential new entrants, we
                  expect to face more competition in the Dominican
                  telecommunications market in the future, which could adversely
                  affect our ability to maintain our market share or require us
                  to lower prices.



         CENTENNIAL, ONE OF OUR COMPETITORS IN THE DOMINICAN REPUBLIC HAS
         PURSUED LEGAL ACTION AGAINST US, WHICH, IF DECIDED AGAINST US, COULD
         RESTRICT OUR INTERNATIONAL BUSINESS IN THE DOMINICAN REPUBLIC AND
         DECREASE OUR REVENUES.



         Centennial, one of our competitors in the Dominican Republic, filed a
complaint against TRICOM USA Inc. with the United States Federal Communications
Commission on September 4, 2001, claiming that:



                                      -11-
<Page>


         o        TRICOM USA and other U.S. carriers of international
                  telecommunications traffic had better termination terms and
                  circuit availability in the Dominican Republic with TRICOM
                  S.A. than Centennial for traffic from the U.S. southbound to
                  the Dominican Republic; and



         o        TRICOM U.S.A.'s actions harm competition in the United States
                  and violate the license granted to TRICOM USA by the Federal
                  Communications Commission.



Centennial requested that the Federal Communications Commission:



         o        require TRICOM USA to stop accepting special concessions from
                  TRICOM, S.A.; and



         o        order TRICOM S.A. to allocate more network capacity to
                  Centennial in the Dominican Republic and to pay to Centennial
                  unspecified damages.



If Centennial prevails, TRICOM USA could be required to pay damages and to
stop accepting any special concessions it receives. In addition, this could
negatively affect, diminish or eliminate the business we generate from
traffic generated in the United States and terminated in the Dominican
Republic. Our revenue derived from traffic generated in the U.S. and
terminated in the Dominican Republic was $45.9 million in 2000, which
represented approximately 20% of our total revenue in 2000.



         BSC OF PANAMA, ONE OF OUR COMPETITORS IN PANAMA, HAS PURSUED LEGAL
         ACTION AGAINST US, WHICH, IF DECIDED AGAINST US, COULD RESTRICT OUR
         EXPANSION INTO PANAMA AND LIMIT OR ELIMINATE OUR ABILITY TO GENERATE
         ADDITIONAL REVENUE.



         BSC of Panama, S.A., a subsidiary of BellSouth Corporation, one of
our competitors in Panama, requested that the Panamanian ENTE REGULADOR DE
LOS SERVICIOS PUBLICOS, or ENTE, investigate TRICOM Panama, S.A. for
pretending to use iDEN technology to provide trunking services, which BSC of
Panama, S.A. alleges violates the Telecommunications Act and the ENTE's
regulations. If BellSouth prevails in this action, we will not be able to
provide our services in Panama using iDEN technology.



         Additionally, BSC of Panama, S.A. obtained a court order on
August 28, 2001 requiring TRICOM Panama to cease all activity relating to the
provision of telecommunications services using the iDEN(R) system. In a related
action, BellSouth additionally seeks damages from us in the amount of US
$20,000,000, which it claims it may sustain if TRICOM Panama begins using the
iDEN(R) system in Panama. We have appealed the order. However, the appeal
process could be lengthy and, even if we ultimately prevail, the construction
of our network and the commencement of our operations could be delayed for
months.



         To date, we have invested $33 million in our expansion in Panama. If
BellSouth prevails in all of its actions, we may be forced to discontinue our
business in Panama and we would not gnerate any revenue from our iDEN(R)
operations in Panama.



         SETTLEMENT RATES FOR INTERNATIONAL TRAFFIC FROM THE UNITED STATES AND
         PUERTO RICO COULD CONTINUE TO DECLINE, WHICH COULD REDUCE OUR
         INTERNATIONAL SETTLEMENT REVENUES AND PROFIT MARGINS FROM THESE
         REVENUES.



         Revenues from incoming international long distance calls represented
approximately 40% of our operating revenues in 1998, 36% in 1999 and 38% in
2000. Approximately 98% of these revenues were attributable to calls
originating in the United States and Puerto Rico. Settlement rates for
traffic between the United States and the Dominican Republic have declined
from $0.41 per minute during 1996 to $0.04 per minute during the third
quarter of 2001. We believe that competitive and regulatory pressures could
continue to push settlement rates lower. Future decreases in settlement
rates, without a corresponding increase in our international long distance
traffic from the United States, would reduce our international settlement
revenues and adversely affect the profit margins that we realize on these
revenues.


         BECAUSE WE ARE RECEIVING AN INCREASING PORTION OF OUR INTERNATIONAL
         MINUTES FROM U.S.-BASED RESELLERS, WE MAY EXPERIENCE SUBSTANTIAL
         FLUCTUATION IN OUR INTERNATIONAL REVENUES.


         Since 1997, we have derived an increasing proportion of international
revenues from U.S.-based resellers, which are companies that typically buy long
distance minutes in bulk and resell the minutes to other companies or individual
end users. During 2000, resellers originated approximately 45% of our
international long distance minutes from the United States to the Dominican
Republic. While we enter into agreements with resellers, they are not required
to provide us with any specified amount of traffic. During the first quarter of
2001, our revenues from resellers declined by 44%, which resulted in a decline
in our international settlement revenues by 22%. The volume of minutes and
revenues we receive from these resellers may vary significantly because of their
uncertain financial condition.



                                      -12-
<Page>


         INTENSE COMPETITION IN U.S. MARKETS AMONG INTERNATIONAL LONG DISTANCE
         CARRIERS HAS RESULTED IN BANKRUPTCY FILINGS BY A NUMBER OF OUR RESELLER
         CLIENTS. WE MAY NOT BE ABLE TO COLLECT MONIES THAT THESE CLIENTS OWE TO
         US.



         During 2001, ten U.S. carriers with which we exchanged, exchange or
contracted at one time to exchange long distance service filed voluntary
petitions for bankruptcy. In seven cases, our subsidiary, TRICOM USA, is an
unsecured, pre-petition and/or post-petition creditor and has claims
aggregating approximately US$1.5 million. TRICOM USA owes such carriers
approximately US$980,000. If TRICOM USA were permitted to net balances, its
claims would be reduced to approximately US$520,000. We may not be able to
net balance or recover any portions of the amounts owed to us. In addition,
we may face substantial delays in resolving net balances or our claims and
may not receive full payment of our claims. In two cases, the bankrupt
carriers applied to prevent us from altering, refusing or discontinuing
services, although the courts in these cases did not grant the requests of
these carriers. We may be compelled to provide service to other carriers in
bankruptcy under terms mandated by the court, which may not be as favorable
to us as terms that we receive from other resellers.



         OUR EFFORTS TO MINIMIZE CREDIT RISKS MAY ADVERSELY AFFECT OUR EFFORTS
TO EXPAND OUR CUSTOMER BASE.



         During 1996, we terminated service for a significant number of mobile
subscribers due to credit considerations, which adversely affected our results
of operations. Since that time, we have instituted measures to minimize consumer
credit risks. However, our efforts to minimize consumer credit risks may not be
successful as we expand and offer our services across many different social and
economic markets, including our expansion in Central America. Moreover, efforts
to minimize credit risks may limit the number of our new subscribers.


         OUR NET GROWTH IN SUBSCRIBERS MAY BE REDUCED BY CUSTOMER DISCONNECTIONS
OR CHURN.


         Our results of operations in the past have been, and in the future may
be, affected by subscriber disconnections. In order to realize net growth in
subscribers, we must replace disconnected subscribers and add new subscribers.
The sales and marketing costs associated with attracting new subscribers are
substantial, relative to the costs of providing service to existing subscribers.
Our average monthly disconnection rate, or "churn rate," during 2000 was 3.1%
for cellular and PCS subscribers and 2.3% for local access line subscribers. If
we are not able to maintain our credit policies, or not otherwise able to limit
churn, we will not experience net growth in subscribers .



         WE MAY NOT HAVE SUFFICIENT RESOURCES TO KEEP PACE WITH CHANGES IN
         TECHNOLOGIES USED TO PROVIDE TELECOMMUNICATIONS SERVICES OR THE
         TECHNOLOGIES THAT WE HAVE CHOSEN TO PROVIDE SERVICE MAY BE LESS POPULAR
         AMONG USERS THAN OTHER TECHNOLOGIES.



         If we do not offer the latest technology, we may not be able to retain
our existing customers or attract new ones. Our digital mobile technology could
become obsolete. Our investment, to date, in our Dominican market exceeds $700
million and we would require substantial investment to replace all or a
substantial part of it and to build our Central American network.



         SPECIAL TAX PROVISIONS CONTAINED IN OUR CONCESSION AGREEMENT ARE
         REQUIRED TO BE APPROVED BY THE DOMINICAN CONGRESS BUT HAVE NOT BEEN TO
         DATE, WHICH MAY CAUSE OUR FUTURE TAXES PAYABLE TO THE DOMINICAN
         GOVERNMENT TO INCREASE.



         Our 1996 concession agreement with the Dominican government , which
grants us our right to operate as a telecommunications provider, provides for
payments to the Dominican government, in lieu of income tax imposed on other
Dominican corporations. Under the Dominican Constitution, provisions of
agreements with the Dominican government that contain exemptions from income tax
only become effective upon approval by the Dominican Congress. Neither our
existing concession agreement, nor the concession agreements of Codetel and
other competitors, all of which contain tax provisions identical to ours, has
been submitted to the Dominican Congress for approval. We are not aware of any
plans of the Dominican government to submit any concession agreements to the
Dominican Congress for approval.



                                      -13-
<Page>


         If our concession agreement is presented to the Dominican Congress,
it may not approve or validate those provisions of the concession agreement
relating to the payment of taxes. If the provisions relating to the payment
of taxes in our concession agreement were to be disapproved by the Dominican
Congress, we believe that Dominican tax law would require the payment of a
tax equal to 25% of our adjusted net income, but never less than 1.5% of
gross revenues, payable in advance on a monthly basis, which is the current
tax regime generally applicable to Dominican corporate taxpayers. For 2000,
this would have resulted in our paying income taxes of $2.5 million compared
to taxes in lieu of income taxes of $10.2 million. However, the calculation
of taxes on the basis applicable to other Dominican corporations could result
in our paying greater taxes than we would otherwise pay under the terms of
our concession agreement.



         WE MAY LOSE REVENUE OR INCUR INCREASED COST AS A RESULT OF FRAUDULENT
         USE OF OUR PCS AND CELLULAR NETWORKS.



         We estimate that our lost revenues from fraudulent use of our PCS
and cellular networks totaled $711,000 during 2000 and $489,000 during the
nine months ended September 30, 2001. Anti-fraud technology continually
becomes obsolete, and we will have to make future expenditures to acquire and
use anti-fraud technology.


         OUR NETWORK OPERATIONS MAY BE VULNERABLE TO HACKING, VIRUSES AND OTHER
DISRUPTIONS.

         "Hacking" involves efforts to gain unauthorized access to information
or systems or to cause intentional malfunctions or loss or corruption of data,
software, hardware or other computer equipment. Hackers, if successful, could
misappropriate proprietary information or cause disruptions in our services.
Security breaches could have a material adverse effect on our business. In
addition, the inadvertent transmission of computer viruses could expose us to a
material risk of loss or litigation and possible liability. Moreover, if a
computer virus affecting our system is highly publicized, our reputation could
be materially damaged and our user traffic may decrease.

RISKS RELATING TO OUR EXPANSION STRATEGY


         WIRELESS TELECOMMUNICATIONS SERVICES COMPANIES HAVE A LIMITED HISTORY
IN OUR EXISTING AND TARGETED MARKETS, ACCEPTANCE OF OUR SERVICES IS UNCERTAIN,
AND WE MAY NOT BE ABLE TO SUCCESSFULLY IMPLEMENT OUR BUSINESS PLAN.



         Due, in part, to the limited history of wireless communications
services in our existing market in the Dominican Republic and our targeted
markets in Central America, we face many uncertainties in our markets that may
affect our ability to grow or implement our business plan. These uncertainties
include:


         o        the size of the markets for wireless communications services;

         o        the penetration rates of these markets;

         o        the ability of potential subscribers to pay subscription and
                  other fees;

         o        the extent and nature of the competitive environment in these
                  markets; and

         o        the immediate and long-term commercial viability of wireless
            communications service in these markets.


         As a result of these uncertainties, we may make significant investments
in developing a network and promoting our digital mobile services in markets



                                      -14-
<Page>


where we may not achieve significant market acceptance for our services. If this
occurs we may be unable to recover our investment in these markets.


         WE MAY NOT BE ABLE TO FINANCE OUR CAPITAL EXPENDITURE NEEDS WHICH COULD
         RESULT IN THE DELAY OR ABANDONMENT OF SOME OR ALL OF OUR DEVELOPMENT
         AND EXPANSION PLANS AND EXPENDITURES.


         We currently anticipate that our capital expenditures will be
approximately $123.8 million in 2001. We believe that we will continue to
expend substantial amounts in subsequent years. We believe our cash generated
by operations and borrowings available to us are sufficient to fund our
capital expenditures for 2001. In the event additional funds are required, we
would be forced to obtain them through additional borrowings, including, if
available, vendor financing or through the public or private sale of debt or
equity securities. Acquisitions or investments may require additional
financing. There can be no assurance that additional financing will be
available to us or, if available, that it can be obtained on terms acceptable
to us or within limitations that are contained in our current or future
financing arrangements. Our ability to access additional funds may be limited
by:


         o        the terms of our existing financing agreements, including
                  restrictive covenants;


         o        conditions in the U.S. and in international markets that may
            adversely affect the availability or cost of capital;



         o        the volatility of the economies of Latin America and Asia, or
            in the local markets in which we operate, which may make lenders
            less likely to extend credit to us;


         o        our high level of indebtedness, which may affect our
            attractiveness as a potential borrower; and


         o        the market's perception of our performance .



         Failure to obtain additional financing could result in the delay or
abandonment of some or all of our development and expansion plans and
expenditures, including the building of our iDEN network in Central America.


         WE DO NOT HAVE EXPERIENCE IN OPERATING A CABLE TELEVISION BUSINESS AND
         IF WE ARE UNABLE TO SUCCESSFULLY INTEGRATE TELECABLE, OUR BUSINESS,
         FINANCIAL CONDITION AND RESULTS COULD BE ADVERSELY AFFECTED.

         We have not previously operated a cable television business. The
success of our acquisition, in part, will depend on our ability to integrate it
into our existing systems. Some of our existing operational, financial and
management systems may be incompatible with or inadequate to effectively
integrate and manage the Telecable systems. In addition, we may not be able to
retain or recruit qualified personnel which may be required. We also may
encounter unexpected operating difficulties, liabilities or contingencies. Any
of these or other factors could significantly delay or even preclude our
realizing synergies or other benefits from our acquisition or place significant
demands on our management and financial resources.


         THE DOMINICAN TELECOMMUNICATIONS REGULATOR RECEIVED OBJECTIONS TO THE
         TRANSFER OF THE CONCESSION GRANTED TO TELECABLE TO OPERATE A CABLE
         NETWORK, WHICH, IF UPHELD, COULD LIMIT OR EVEN PRECLUDE THE OPERATION
         OF THE CABLE BUSINESS WE ACQUIRED.

         On November 16 and November 19, 2001, Indotel and we received notices
of objections to the transfer of the concession granted to Telecable for the
operation of its cable business. The objecting parties are two cable
companies that operate networks in localities of the interior of the
Dominican Republic and an association of cable companies from that region.
The objections seem to allege that certain licenses granted to Telecable are
invalid for lack of use. If Indotel were to decide in favor of the
objections, it could invalidate the transfer of the concession and impose
fines on us. We believe, based upon recent challenges to concessions
transfers in which objections did not prevail, that it is unlikely that the
objections will prevail. Moreover, TRICOM's own concession allows us to
provide video and cable services, so that even if the objections are upheld,
we believe that we could use our own concession to provide the cable services
currently provided in reliance on the Telecable concession. However, it also
is possible that Indotel would limit the areas in which we can provide
services so that we do not compete in markets currently served by the
companies that raised objections.



         SOCIAL, POLITICAL AND ECONOMIC CONDITIONS IN CENTRAL AMERICAN MARKETS,
         INTO WHICH WE PLAN TO EXPAND, MAY CAUSE VOLATILITY IN OUR OPERATIONS
         AND ADVERSELY AFFECT OUR REVENUES FROM THESE MARKETS.



         We plan to expand into Central American telecommunications markets in
which we have not operated previously and these markets will present numerous
challenges to us. Poor social, political and economic conditions, matters over
which we have no control, could inhibit our market entry and subsequent
performance. Social and political conditions in parts of the Central American
markets are volatile and may cause the nature and results of our operations to
fluctuate. Historically, volatility in parts of the Central American markets has
been caused by:


         o        significant governmental influence over many aspects of local
            economies;

         o        political and economic instability;



                                      -15-
<Page>

         o        unexpected changes in regulatory requirements;

         o        social unrest;

         o        slow or negative growth;

         o        imposition of trade barriers;

         o        wage and price controls;


         o        natural disasters; and


         o        this volatility could make it difficult for us to sustain our
            operations in these markets, which could adversely affect our
            business.


         GOVERNMENT REGULATIONS IN VARIOUS COUNTRIES MAY HAMPER OUR ABILITY TO
         GROW AND IMPLEMENT OUR STRATEGY.



         In each market that we are considering, one or more regulatory entities
regulate the licensing, construction, acquisition, ownership and operation of
our wireless communications systems. Adoption of new regulations, changes in the
current telecommunications laws or regulations or changes in the manner in which
they are interpreted or applied could adversely affect our operations. Because
of the uncertainty as to the interpretation of regulations in some countries in
which we may operate, we may not always be able to provide the services we have
planned in each market. It is possible that, in the future, we may face
additional regulatory prohibitions or limitations on our services or on foreign
ownership of telecommunications companies. Inability to provide planned services
could make it more difficult for us to compete in the affected markets. These
issues could affect our ability to operate in targeted markets, and therefore
impact our growth and strategy plans.



         IN CENTRAL AMERICAN MARKETS, GOVERNMENT-OWNED OR AFFILIATED
         TELECOMMUNICATIONS COMPANIES, WIRELINE MONOPOLY OPERATORS AND
         MULTINATIONAL TELECOMMUNICATION COMPANIES MAY HAVE SIGNIFICANT
         COMPETITIVE ADVANTAGES THAT WOULD HINDER THE DEVELOPMENT OF OUR
         WIRELESS BUSINESS THERE.


         In some markets in Central America, we may not be able to compete
effectively against :


         o        incumbent government-owned telecommunications companies;



         o        formerly government-owned companies in which the government
                  may or may not retain a significant interest;



         o        wireline monopoly operators; and



         o        multinational telecommunications companies.



         We may be at a competitive disadvantage in these markets because these
competitors may have:


         o        close ties with national regulatory authorities;

         o        control over connections to local telephone lines;

         o        larger customer base;


         o        greater managerial and technical talent;



         o        ability to cut prices;



         o        better name recognition;

         o        larger spectrum positions;

                                      -16-
<Page>


         o        greater managerial and technical talent;



         o        ability to cut prices;



         o        larger coverage areas than those of our operating companies;
            or



         o        the ability to subsidize competitive services with revenues
            generated from other services they provide.



         For example, in Panama, Cable & Wireless plc has temporary exclusivity
over wireline services and only an affiliate of BellSouth and Cable &
Wireless are licensed to provide wireless services. These competitors, among
others, may adversely affect our ability to develop our wireless business in
Central America.



         INITIALLY, OUR COVERAGE IN CENTRAL AMERICAN MARKETS WILL NOT BE AS
         EXTENSIVE AS THOSE OF OTHER WIRELESS SERVICE PROVIDERS IN OUR MARKETS,
         WHICH MAY LIMIT OUR ABILITY TO ATTRACT AND RETAIN CUSTOMERS.



         At first, we plan to provide wireless services only in the metropolitan
areas and large business centers of Central America. Since our digital mobile
networks will not initially offer nationwide coverage in the countries in which
we are considering and our technology limits our potential roaming partners, we
may not be able to compete effectively with other wireless providers in our
markets.



         Many of the wireless providers in our targeted markets have entered
into roaming agreements with each other, which permit these providers to offer
coverage to their subscribers in each other's networks. While the iDEN
technology that we will deploy is compatible with GSM technology (Global System
for Mobile Communications), it is not compatible with any other wireless
technology operating in our spectrum. As a result, we cannot enter into roaming
agreements with the operators of these other networks. Our customers also will
not be able to roam on other systems using technology identical to or compatible
with ours where we do not have a roaming agreement. As a result, we will not be
able to provide coverage to our subscribers outside of our planned operating
digital mobile markets until:



         o        we build out additional networks in areas outside our
            initially planned markets;



         o        other operators deploy technology compatible to the technology
            that we will deploy in markets outside of our planned coverage
            areas and we enter into roaming agreements with those operators; or



         o        handsets that can be used on both our wireless communications
            networks and networks deploying other technologies become available
            and we enter into roaming agreements with the operators of those
            networks.



         OUR EQUIPMENT IS MORE EXPENSIVE THAN THAT OF SOME COMPETITORS IN
         CENTRAL AMERICA MARKETS, WHICH MAY AFFECT OUR ABILITY TO ESTABLISH AND
         MAINTAIN A SIGNIFICANT SUBSCRIBER BASE.


         We will market multi-function digital handsets. The higher cost of our
equipment, as compared to analog handsets and some digital handsets that do not
incorporate a comparable multi-function capability, may make it more difficult
or less profitable for us to attract customers. This may reduce our growth
opportunities or profitability.


         WE MAY FACE DELAYS CONSTRUCTING OUR DIGITAL MOBILE NETWORK IN CENTRAL
AMERICA WHICH WOULD HARM OUR OPERATIONS.



         We may not be able to complete our currently planned construction
successfully or in a timely manner. If we do not, our ability to establish a
subscriber base, improve the transmission quality of our digital mobile services
and expand our service area could be impaired. It may be necessary to


                                      -17-
<Page>


substantially change our proposed plans or otherwise alter our currently
anticipated time frames or budgets because we are not able to:



         o        locate suitable sites for communications sites or towers;



         o        obtain any required zoning variances or other governmental or
            local regulatory approvals;



         o        negotiate acceptable purchase, lease, or other agreements; or



         o        obtain quality supplies in a timely manner, if at all.



         We also may encounter delays caused by


         o        frequency cross-interference with other radio spectrum users,
            including television stations;


         o        shortages of equipment or skilled labor;



         o        engineering or environmental problems;



         o        work stoppages;



         o        weather interference; and


         o        unanticipated cost increases.


         WE ARE NOT EXPERIENCED IN SELLING AND MARKETING IDEN SERVICES OR IN
         CENTRAL AMERICAN MARKETS WHICH COULD AFFECT OUR ABILITY TO ESTABLISH OR
         MAINTAIN A SIGNIFICANT SUBSCRIBER BASE.



         Once our digital mobile network operations are in place in a particular
market, the development of a significant, quality subscriber base depends on the
success of our sales and marketing efforts and the receptiveness of the
marketplace to our services. We have limited experience in marketing iDEN
services and local conditions in our target markets may require us to modify our
sales and marketing efforts or rely, in part, on the efforts of independent
dealers and distributors to market our services. If the sales and marketing
teams of our operating companies and the independent dealers and distributors
are not able to establish a large subscriber base consisting of quality
customers in our new markets, our revenues will not grow as planned.


         SINCE WE RELY PRINCIPALLY ON ONE SUPPLIER TO IMPLEMENT OUR DIGITAL
         MOBILE NETWORKS, ANY FAILURE OF THAT SUPPLIER TO PERFORM COULD HURT OUR
         OPERATIONS.


         Motorola is currently our sole source for the iDEN digital network
equipment and handsets used throughout our markets. If Motorola fails to deliver
necessary technology improvements and enhancements and system infrastructure
equipment and handsets on a timely, cost-effective basis, or discontinues
providing this technology altogether we would not be able to service our
existing subscribers or add new subscribers.



         MOTOROLA MAY SUPPLY IDEN TECHNOLOGY TO OTHER COMPANIES WHICH COULD
         NEGATIVELY AFFECT OUR COMPETITIVE POSITION IN THE CENTRAL AMERICA.



         Motorola, which supplies the iDEN system that we use in Central
America, agreed that it would not sell iDEN technology to anybody else for use,
before agreed upon dates, in Panama, Costa Rica, Guatemala, Honduras, El
Salvador and Nicaragua. Its agreement was conditioned upon our placing orders
for systems in each of those countries by specified dates. Except for Panama, we
have not placed the orders necessary to preserve the head start afforded to us
by Motorola's agreement. As a result, Motorola is free to provide the technology
in those countries to anybody else. If it did so, we could lose an important
competitive advantage to us.

         CONCERNS ABOUT HEALTH RISKS ASSOCIATED WITH WIRELESS EQUIPMENT MAY
REDUCE THE DEMAND FOR OUR SERVICES.

         Portable communications devices have been alleged to pose health risks,
including cancer, due to radio frequency emissions from these devices. The
actual or perceived risk of mobile communications devices could adversely affect
us through a reduction in subscribers, reduced network usage per subscriber or
through reduced financing available to the mobile communications industry.
Studies performed by wireless telephone equipment manufacturers have
investigated these allegations and additional studies are ongoing.

RISKS RELATING TO OUR PRINCIPAL MARKET, THE DOMINICAN REPUBLIC


         OUR FINANCIAL CONDITION AND RESULTS OF OPERATION COULD BE ADVERSELY
AFFECTED BY DOWNTURNS IN THE DOMINICAN ECONOMY.



         Most of our operations are conducted in, and most of our customers are
located in, the Dominican Republic. Accordingly, our financial condition and
results of operations are substantially dependent on economic conditions in the
Dominican Republic. While the Dominican Republic's GDP has grown every year
since 1991, this growth may not continue in the future. Future developments in
the Dominican economy could impair our ability to proceed with our business
strategies, our financial condition or our results of operations. Our financial
condition and results of operations also could be adversely affected by changes
in economic or other policies of the Dominican government or other political or
economic developments in or affecting the Dominican Republic, as well as
regulatory changes or administrative practices of Dominican authorities, over
which we have no control.



         POVERTY, SOCIAL UNREST AND SHORTAGES OF BASIC SERVICES IN THE DOMINICAN
         REPUBLIC COULD AFFECT THE USE OF TELECOMMUNICATIONS SERVICES, WHICH
         WOULD DECREASE OUR REVENUES.



         The Dominican Republic has widespread poverty. As recently as November
1997, the country experienced riots, partly as a result of price increases and
shortages of water and electricity. Several state-owned companies have been
privatized, including the country's state-owned electric utility company, and
there can be no assurance that the implementation of these privatizations will
not cause social unrest. Any increase of poverty, social unrest or shortage of
basic services could adversely affect the use of telecommunications services.



         ALTHOUGH INFLATION IN THE DOMINICAN REPUBLIC HAS BEEN MODERATE SINCE
         1990, INCREASES IN THE INFLATION RATE WOULD ADVERSELY AFFECT THE
         DOMINICAN REPUBLIC'S ECONOMY AND THE DEMAND FOR OUR TELECOMMUNICATIONS
         SERVICES.



         Inflation has moderated in the Dominican Republic since 1991, following
an austerity program instituted by the Dominican government. According to the
Central Bank, the annual rates of inflation were 3.9% for 1996, 8.4% for 1997,
7.8% for 1998, 5.1% for 1999 and 9.0% for 2000. However, the country has
experienced high levels of inflation in the past, including an inflation rate of
79.9% for 1990. Any increase in the value of the U.S. dollar against the
Dominican peso directly affects the Dominican Republic's inflation rate because
the Dominican Republic relies heavily on imports from the United States of raw
materials and consumer goods. High inflation levels could adversely affect the
Dominican Republic's economy and reduce demand for telecommunications services.



         THE VOLATILITY AND DEPRECIATION OF THE DOMINICAN PESO AGAINST THE U.S.
         DOLLAR COULD REDUCE THE AMOUNT OF CASH WE WILL HAVE TO REPAY OUR
         INDEBTEDNESS OR FUND OUR OPERATIONS, INCLUDING THE PURCHASE OF
         TELECOMMUNICATIONS EQUIPMENT.


         For 1998, 1999 and 2000, we earned between 55% and 65% of our operating
revenues in Dominican pesos and the remainder of our operating revenues in
foreign currency, primarily in U.S.


                                      -19-
<Page>


dollars. The percentage of operating revenues in Dominican pesos could increase
if we successfully increase our share in Dominican local markets in accordance
with our strategy. The Dominican peso has depreciated in value against the U.S.
dollar in the past and may be subject to fluctuations in the future. Most of our
outstanding indebtedness is U.S. dollar-denominated and must be paid in U.S.
dollars. Vendors of telecommunications equipment all require that we pay for
equipment in U.S. dollars. The devaluation of the Dominican peso could affect
adversely our ability to purchase U.S. dollars in order to service our debt
obligations and pay our equipment vendors. Our purchase of substantial amounts
of U.S. currency in Dominican markets could adversely affect the value of the
Dominican peso in relation to the U.S. dollar, and make these purchases more
costly for us.


RISKS RELATED TO THIS OFFERING

         THE PRICE OF OUR ADSs MAY DECLINE BEFORE OR AFTER THE SUBSCRIPTION
RIGHTS EXPIRE.


         The public trading market price of our ADSs may decline after you
exercise your subscription rights. If that occurs, you will have committed to
buy ADSs at a price above the prevailing market price and you will have an
immediate unrealized loss. Moreover, following the exercise of subscription
rights you may not be able to sell your ADSs at a price equal to or greater than
the subscription price. Until certificates are delivered upon expiration of this
offering, you may not be able to sell the ADSs you purchase in this offering.
Certificates representing our ADSs purchased will be delivered as soon as
practicable after expiration of this offering.



         ONCE YOU EXERCISE YOUR SUBSCRIPTION RIGHTS, YOU MAY NOT REVOKE THE
         EXERCISE EVEN IF YOU NO LONGER DESIRE TO INVEST IN US.



         Once you exercise your subscription rights, you may not revoke the
exercise. Therefore, even if circumstances arise after you have subscribed in
the offering that eliminate your interest in investing in our ADSs, you will be
required to purchase the ADSs for which you subscribed.



         GFN WILL OWN STOCK WITH A MAJORITY OF THE VOTING POWER AND WILL BE ABLE
TO DETERMINE MANY DECISIONS CONCERNING US.



         GFN beneficially owns 11,486,720 shares of Class B stock having
approximately 57% of our voting power and, in addition, 675,024 shares of
Class A common stock. GFN's purchase of        shares of Class A Common Stock
would increase its percentage of the voting power to o%, if all of the shares
offered are subscribed, and to o% if only GFN subscribes for ADSs. Motorola,
the other shareholder with shares of Class B stock, beneficially owns
approximately 38% of the voting power, which, if Motorola does not exercise
its rights, will be reduced to o% if all of the ADSs offered are subscribed
for and to o% if only GFN subscribes for ADSs. Accordingly, GFN and Motorola
are able to control the election of directors and all other matters which are
subject to a vote of shareholders. This concentration of ownership may have
the effect of delaying or preventing a change of control of TRICOM even if
this change of control would benefit all of our shareholders.



         THE SHARES UNDERLYING YOUR ADRS MAY NOT BE VOTED IN THE MANNER YOU
DIRECT, IF AT ALL.



         You may instruct The Bank of New York, the depositary of the ADRs, to
vote the shares underlying your ADRs only if we ask the depositary to ask for
your instructions. Otherwise, you will not be able to exercise your right to
vote unless you withdraw the shares represented by the ADRs. We have asked and
intend to ask the depositary to ask you for voting instructions. However, you
may not receive voting materials from the depositary in time to instruct it to
vote your shares or for you to withdraw your shares. The depositary is not
responsible for failing to carry out your voting instructions. Therefore, you
may not have the ability to vote your shares and their may not be anything you
can do to prevent it or correct it.


                                      -20-
<Page>


         WE HAVE A LARGE AMOUNT OF SHARES ELIGIBLE FOR FUTURE SALE, WHICH COULD
         HAVE A NEGATIVE IMPACT ON THE MARKET PRICE OF OUR ADSS.



         After this offering, GFN and Motorola will own a total of 19,144,
544 shares of our Class B stock, each of which is convertible into one share
of Class A common stock. GFN also will own ___ shares of Class A common
stock. We have also issued 3,375,000 shares of Class A common stock in our
acquisition of Telecable. GFN has purchased 675,024 of those shares from the
Telecable shareholders. GFN, Motorola, and the former shareholders of
Telecable have registration rights which would enable them to sell shares. We
cannot predict the effect, if any, that future sales of ADSs, or the
availability of shares for sale, would have on the market price prevailing
from time to time. Sales by any of GFN, Motorola or the former shareholders
of Telecable of substantial amounts of our ADSs in the public market, or the
perception that sales could occur, could adversely affect prevailing market
prices for our common stock. A reduction in the market price of our ADSs
could impair our ability to raise additional capital through future public
offerings of our equity securities.



         THE OFFERING WILL RESULT IN THE REDUCTION OF BOOK VALUE PER SHARE AND
         IF YOU DO NOT FULLY SUBSCRIBE YOU WILL BE DISPROPORTIONATELY AFFECTED.



         If you do not subscribe for ADSs, your percentage ownership of
TRICOM will be reduced by ___%. The market price of our ADSs is currently
less than the book value per share at September 30, 2001, approximately $6.98
per share, and the book value per share will be reduced by the issuance of
ADSs in this offering to approximately $___ per share, if we receive
subscription for all ADSs that we are offering. If you do not fully exercise
your rights, your participation in the book value of the shares will be
affected disproportionately to your pre-offering percentage ownership.



         IF YOU DO NOT ACT PROMPTLY AND FOLLOW INSTRUCTIONS CAREFULLY , YOU MAY
         NOT BE ABLE TO PARTICIPATE IN THIS OFFERING AND YOUR CURRENT INVESTMENT
         COULD BE DILUTED.



         Shareholders who desire to purchase shares in this rights offering must
act promptly to ensure that all required forms and payments are actually
received by our subscription agent, The Bank of New York, prior to the
expiration date. If you fail to complete and sign the required subscription
forms, send an incorrect payment amount, or otherwise fail to follow the
subscription procedures that apply to your desired transaction, we may,
depending on the circumstances, reject your subscription or accept it only to
the extent of the payment received.

                               RECENT DEVELOPMENTS



CABLE ACQUISITION



         On October 26, 2001, we acquired the shares of TCN Dominicana, S.A.,
a wholly-owned Subsidiary of Telecable Nacional, C. por A., that owns and
operates the largest multi-channel system in the Dominican Republic's pay-TV
market including the concession granted by the Dominican government to
operate a cable system. The transaction was valued at approximately $1,130
per subscriber equivalent or $63.7 million, payable $41.8 million in cash and
with 3,375,000 shares of our Class A common stock.



         TCN Domincana is the leader of the Dominican cable TV market with a
43% market share, serving approximately 52,000 residential subscribers with
approximately 150,000 homes passed and an additional 8,000 commercial
customers. TCN Domincana operates primarily in the capital city of Santo
Domingo, where, based on market information available to us, we believe it
has a 90% market share, and the resort cities of Puerto Plata and La Romana.
Approximately 70% of TCN Domincana's cable network has been recently upgraded
to 750 MHz; and it is expected that the network will be fully upgraded by
2002. For the year ended December 31, 2000, Telecable had revenues of
approximately $17.0 million, and earnings before taxes of approximately $2.9
million.



         On November 16 and 19, 2001, Indotel and we received notice of
objections to the transfer of the concession granted to Telecable for the
operation of its cable business. The objecting parties are two cable
companies that operate networks in localities of the interior of the
Dominican Republic and an association of cable companies from that region.
The objections seem to allege that certain licenses granted to Telecable are
invalid for lack of use. If Indotel were to decide in favor of the
objections, it could invalidate the transfer of the concession and impose
fines on us. We believe, based upon recent challenges to concessions
transfers in which objections did not prevail, that it is unlikely that the
objections will prevail. Moreover, TRICOM's own concession allows us to
provide video and cable services, so that even if the objections are upheld,
we believe that we could use our own concession to provide the cable services
currently provided in reliance on the Telecable concession. However, it also
is possible that Indotel would limit the areas in which we can provide
services so that we do not compete in markets currently served by the
companies that raised objections. Under the telecommunications regulations,
we have ten days from the date of notice of an objection to respond.
Thereafter, Indotel must decide to authorize or reject the transfer within
the succeeding forty five days. Any decision by Indotel may be appended.



LITIGATION



         ALL AMERICA LITIGATION



         On August 13, 2001, Instituto Dominicano de Telecomunicaciones, or
Indotel, the Dominican telecommunications regulator, issued an order, in
response to a complaint filed by All America, a subsidiary of Centennial,
that we are not dominant in the Dominican market and that the interconnection
agreement we offered to All America was not discriminatory. The
interconnection agreement that we offered to enter into with All America was
the same as we entered into with France Telecom in the Dominican Republic and
which, we understand, All America has with Codetel and which Codetel has with
France Telecom. Indotel further ruled that if we granted to All America the
economic concessions that it seeks from us, the allowance would create
discrimination against other carriers in the Dominican Republic, violating
the Dominican law and the Dominican constitution.



         On September 14, 2001, Indotel issued an order, in response to a motion
submitted by All America for reconsideration of the August 13, that ratified the
August 13 order and ordered us and All America to enter into an interconnection
agreement on substantially the terms and conditions that we proposed.



         On September 4, 2001, Centennial and its affiliates filed a complaint
against TRICOM USA Inc. with the United States Federal Communications
Commission claiming that



         o        We refused to provide Centennial's affiliate in the Dominican
                  Republic with sufficient facilities and reasonable,
                  nondiscriminatory terms for connecting traffic between ours
                  and its network in the Dominican Republic.



         o        Centennial should not pay to TRICOM, S.A. the market rate for
                  terminating calls to TRICOM customers in the Dominican
                  Republic determined by Indotel, approximately US$.042 per
                  minute, but should pay $US.011 per minute; our refusal to
                  agree to this rate is discriminatory; and even if Centennial
                  pays the same international termination rate as TRICOM USA,
                  TRICOM USA gets a benefit because it is affiliated with
                  TRICOM, S.A.


                                      -22-
<Page>


         o        We engage in discriminatory behavior because other U.S.
                  carriers including TRICOM USA get better interconnection
                  capacity from TRICOM, between the United States and the
                  Dominican Republic than does Centennial.



         o        We are harming competition in the United States by limiting
                  the number of interconnection facilities we have made
                  available to connect calls from Centennial's customers to
                  ours, inflating the price for local termination of
                  international traffic and refusing in general to deal with
                  Centennial on a nondiscriminatory basis.



         o        We are violating the conditions of the license granted to
                  TRICOM USA by the FCC to operate as a facilities based carrier
                  which provides that neither TRICOM USA nor any persons
                  controlling it would participate in any favorable
                  interconnection arrangements or special concessions not
                  available to other U.S. carriers.



         Centennial requests that the FCC:



         o        order TRICOM USA to cease accepting special concessions from
                  TRICOM;



         o        require TRICOM USA and TRICOM to provide adequate
                  interconnection capacity to Centennial and reduce the access
                  charge to a level consistent with costs;



         o        find that TRICOM USA is liable to Centennial for damages to
                  compensate Centennial for the losses that it suffered as a
                  result of TRICOM's violations of law and the FCC's rules; and



         o        revoke TRICOM USA's Section 214 license if TRICOM USA does not
                  stop receiving special concessions from TRICOM



         We replied to Centennial's complaint with the FCC on October 13, 2001.
We responded that:

         o        Indotel is the regulator with jurisdiction over the complaint
                  and Centennial is attempting to appeal the decision by
                  Indotel in the action brought by All America against TRICOM in
                  the Dominican Republic;

         o        Centennial failed to provide any evidence that TRICOM USA
                  accepts special concessions from TRICOM; and


         o        The relief sought by Centennial is improper as TRICOM USA
                  owns no facilities in the Dominican Republic and the FCC has
                  no jurisdiction over TRICOM, which is the only entity that
                  could provide the interconnection capacity sought by All
                  America.

         We requested that the FCC reject jurisdiction over the matter or deny
the relief sought by Centennial in its entirety.


         On November 13, 2001, Indotel informed us that it would impose monetary
sanctions on All America if it did not execute within five days the
interconnection agreement that we had proposed and which Indotel determined in
August 2001, among other things, was not discriminatory.

         On November 19, 2001, All America executed the interconnection
agreement that we had proposed.






BELLSOUTH LITIGATION



         On May 8, 2001, BSC of Panama, S.A., a subsidiary of BellSouth,
which owns one of the two cellular telecommunications concessions granted by
the Panamanian government, requested that the Panamanian regulator, ENTE
REGULADOR DE LOS SERVICIOS PUBLICOS, or ENTE, investigate TRICOM Panama, for
violations of the Telecommunications Act and the ENTE's regulations.
BellSouth claimed that TRICOM Panama:



         o        will use its iDEN based trunking services to provide cellular
                  telecommunications services, in violation of our license; and



         o        although we proved that our iDEN system has been modified to
                  disable "hand off" capabilities, the fact that the equipment
                  has these capabilities represents a breach of regulations and
                  our license.



         The ENTE has not issued any ruling on BellSouth's request, but has
stated publicly that Panamanian regulations do not limit the provision of mobile
services to a particular technology.



         On August 24, 2001, BellSouth requested that the ENTE initiate a legal
review before the Third Chamber of the Panamanian Supreme Court of Justice, of
the interpretation given by the ENTE to the definition of "Conventional Trunking
System Services." BellSouth alleges that the interpretation given by the ENTE
to the definition of "Conventional Trunking System Services," found in
Resolution No. JD-025 of December 12, 1996 violates several articles of the
Telecommunications Act, including that the ENTE's interpretation allows a
trunking service provider to use any mobile system, including any type of
cellular systems, as long as the "Hand-Off" capabilities is disabled. BellSouth
claims that this violates




                                      -23-
<Page>


the Telecommunications Act, which states that cellular services are a Type A
Service that can only be provided by BellSouth and the other holder of a Type A
License, Cable & Wireless.



         The ENTE has replied that it only regulates services and not
technology and that the definition of "Conventional Trunking System Services"
protects the temporary exclusivity regime given to cellular services because
it does not allow the participation of new cellular service providers in the
Panamanian market. The license given to TRICOM Panama is for the operation of
conventional trunking services which it plans to operate with the iDEN system.



         The legal review by the Third Chamber of the Panamanian Supreme Court
of Justice requested by BellSouth cannot be undertaken until the Supreme Court
resolves a constitutional review regarding the lack of procedure for it to
undertake a legal review of the sort sought by BellSouth. To date, the Supreme
Court has not indicated whether it will review the procedure.



         On August 28, 2001, BellSouth obtained a precautionary order from
the Seventh Civil Court of the First Judicial Circuit requiring TRICOM Panama
to cease all activity directly or indirectly related to the installation and
supply of telecommunication services using Motorola's iDEN system. This order
forms part of a tort claim, submitted by BellSouth on September 4, 2001,
against TRICOM for US$20,000,000 for the possible damages that TRICOM Panama
may cause BellSouth in the event that TRICOM Panama initiates operations of
an iDEN-based trunking service.



         On September 11, 2001 TRICOM Panama submitted a motion before the
Seventh Civil Court to substitute a bond for the precautionary order to cease
its activities and at the same time appealed to the Superior Civil Chamber
the precautionary order itself. On October 1, 2001, the Seventh Civil Court
denied TRICOM Panama's motion and, on October 8, 2001, TRICOM Panama also
appealed this decision to the Superior Civil Chamber. The TRICOM Panama
defense is based on the following principles:



          o      only the ENTE has by law the power to discontinue public
                 utilities services;



          o      this precautionary measure can only be applied to real
                 property (not to personal property); and



          o      there is no imminent damage that justifies the precautionary
                 measure.



          On September 11, 2001, BellSouth submitted a complaint stating that
TRICOM Panama was in default of the court order.



         TRICOM Panama also submitted a motion to the Seventh Civil Court to
dismiss BellSouth's tort claim and to invalidate the precautionary order,
due to the court's lack of jurisdiction over a matter that should be decided
by the ENTE. On September 28, 2001, TRICOM Panama filed a US$1,000,000
damages counterclaim against BellSouth for the public campaign set against
TRICOM Panama by BellSouth and for the unfounded investigation requested
before the ENTE.



          We believe, based on the advice of our Panamanian legal counsel,
that BellSouth should not succeed in its claims because:



          o     BellSouth cannot claim any damages caused by TRICOM Panama
                activities, since TRICOM Panama operations are protected
                under a legitimate Conventional Trunking System Services
                license.



          o     The Ente is the only authority empowered to declare that the
                telecommunications services to be provided by TRICOM Panama
                are not conventional trunking services, or that the iDEN
                system cannot be used to provide conventional trunking
                services.



          o     TRICOM Panama has yet to finish installation of their
                telecommunication equipment and has not begun to advertise or
                offer their services, therefore, BellSouth cannot prove any
                possible damages derived from TRICOM Panama's operations.



         On November 5, 2001, TRICOM Panama requested that the ENTE investigate
BellSouth for violations of the Telecommunications Act and its concession
agreement on account of the failure of BellSouth to:

         o        recognize the jurisdiction of the ENTE;

         o        follow proper procedure in connection with the precautionary
                  measure it obtained; and

         o        provide interconnection.


         On November 13, 2001, upon the request of BellSouth, the Seventh Civil
Court issued an order giving notice to Cable & Wireless of the precautionary
order issued against TRICOM Panama in August 2001. TRICOM Panama and Cable &
Wireless have negotiated the terms of an interconnection agreement.

         On November 16, 2001, TRICOM Panama sought protection from the
Superior Tribunal of the Supreme Court on account of the August precautionary
order which violated its constitutional right to due process and trial before
a body of competent jurisdiction.

                                 USE OF PROCEEDS


         We will use the net proceeds from this offering for general corporate
purposes, including to fund in part the acquisition of Telecable, and for
working capital. The purchase price, approximately $63.7 million, is payable
$41.8 million in cash and by the issuance of 3,375,000 shares of Class A common
stock.



         Our gross proceeds from the rights offering depend on the number of
shares that are purchased. If all of the subscription rights offered by this
prospectus are exercised, then we will receive proceeds of approximately $105
million in cash, including amounts previously advanced to us by GFN.

                                  THIS OFFERING


      BEFORE EXERCISING ANY RIGHTS, YOU SHOULD READ CAREFULLY THE INFORMATION
      SET FORTH UNDER THE "RISK FACTORS" BEGINNING ON PAGE 10.


THE RIGHTS


         As soon as practicable after the date of this prospectus, we are
distributing, at no charge, to holders of our ADSs, Class A common stock and
Class B stock as of 5:00 p.m., New York City time, on the record date of [____],
2001, ___ non-transferable subscription rights to purchase additional ADSs for
every ADS, share of Class A common stock and share of Class B stock owned at
that time. You will not receive fractional subscription rights, but instead we
will round your number of subscription rights down to the nearest whole number.
Each right entitles you to purchase one ADS for the subscription price. On July
25, 2001, the day on which we announced this offering, the last reported sales
price for our ADSs on the NYSE was $6.00 per share. On the date of this
prospectus, the last reported sales price for our ADSs on the NYSE was $___ per
share.


RECORD DATE


         [_______], 2001 at 5:00 p.m., New York City time. Only our
shareholders as of the record date will receive rights to subscribe for new
ADSs. This includes both holders of Class A common stock and of Class B
stock, which is identical in all respects to our Class A common stock except
that each share of Class B stock has ten votes per share. The Bank of New
York as depository, is the record holder of all shares of Class A common
stock represented by ADSs. We have instructed the Bank of New York to make
these rights available to holders of our ADSs.


SUBSCRIPTION PRICE

         The subscription price is $[__________] per ADS, payable in cash. All
payments must be cleared on or before the expiration date.


BASIC SUBSCRIPTION PRIVILEGE


         You are entitled to purchase one newly-issued ADS at the subscription
price for each right exercised.


OVERSUBSCRIPTION PRIVILEGE



         If you exercise your basic subscription privilege in full, you
may also subscribe for additional shares that other shareholders have not
purchased under their basic subscription privilege. You may purchase a
percentage of the unsubscribed shares equal to your percentage ownership of
our Class A common stock (including shares represented by ADSs) and Class B
stock on the record date. If there are not enough shares available to fill
all such subscriptions for additional shares, the available shares will be
allocated pro rata based on the number of shares each subscriber for
additional shares has purchased under the basic subscription privilege. We
will not allocate to you more than the number of shares you have actually
subscribed and paid for.



         You are not entitled to exercise the oversubscription privilege unless
you have fully exercised your basic subscription privilege. For this purpose,
you would only count the shares you own in your own name, and not other shares
that might, for example, be jointly held with a spouse, held as a custodian for
someone else, or held in an individual retirement account.



         You can elect to exercise the oversubscription privilege only at the
same time you exercise your basic subscription privilege in full.




                                      -28-
<Page>


         In exercising the oversubscription privilege, you must pay the full
subscription price for all the shares you are electing to purchase. If we do not
allocate to you all of the shares you have subscribed for under the
oversubscription privilege, we will refund by mail to you any payment you have
made for shares which are not available to issue to you, promptly after
completion of this offering. Interest will not be payable on amounts refunded.



         Banks, brokers and other nominees who exercise the oversubscription
privilege on behalf of beneficial owners of shares must report certain
information to the subscription agent, The Bank of New York, and us and record
certain other information received from each beneficial owner exercising rights.
Generally, banks, brokers and other nominees must report



         o        the number of shares held on the record date on behalf of each
                  beneficial owner;



         o        the number of rights as to which the basic subscription
                  privilege has been exercised on behalf of each beneficial
                  owner;



         o        that each beneficial owner's basic subscription privilege held
                  in the same capacity has been exercised in full; and



         o        the number of shares subscribed for under the oversubscription
                  privilege by each beneficial owner.



         If you complete the portion of the subscription certificate to exercise
the oversubscription privilege, you will be representing and certifying that you
have fully exercised your basic subscription privilege as described above. You
must exercise your oversubscription privilege at the same time you exercise your
basic subscription privilege.



REASONS FOR OFFERING.



         We are seeking additional equity. GFN, one of our major shareholders,
has committed to provide to us $40 million in additional equity. Our board of
directors has chosen to give you the opportunity to buy more shares on the same
basis as GFN. GFN already has advanced funds to us on an interest-free basis
which will be used to subscribe for ADSs on the same terms and conditions
offered to all shareholders. The shares to be received by GFN, however, will not
be registered under the U.S. Securities Act of 1933.


THE BOARD MAKES NO INVESTMENT RECOMMENDATIONS TO SHAREHOLDERS.

         Our board of directors has approved but does not make any
recommendation to you about whether you should exercise any rights. In making
the decision to exercise or not exercise your rights, you must consider your own
best interests.


         If you choose not to exercise your subscription rights in full, your
relative ownership interest in us will be diluted. In addition, our book
value per share at September 30, 2001 was approximately $6.98 per share and
the book value per share will be reduced by the issuance of ADSs in this
offering to approximately $o per share, if we receive subscriptions for all
ADSs that we are offering. If you exercise rights, you risk investment loss
on new money invested. The trading price of our ADSs may decline below the
subscription price. We cannot assure you that the subscription price will
remain below any trading price for our ADSs or that its trading price will
not decline to below the subscription price during or after this offering.
For a summary of some of the risks a new investment would entail, see "Risk
Factors" beginning on page 10.


EXPIRATION TIME AND DATE.



                                      -29-
<Page>

         The rights expire on [_________], at 5:00 p.m., New York City time. We
have the option of extending the expiration date for any reason, although
presently we do not intend to do so. Rights not exercised by the expiration date
will be null and void.


         In order to exercise rights in a timely manner, you must ensure that
the subscription agent actually receives, prior to expiration of the rights, the
properly executed and completed subscription certificate together with full
payment for all ADSs you wish to purchase.


NO REVOCATION


         You are not allowed to revoke or change your exercise of rights after
you send in your subscription forms and payment, even if you later learn
information about us that you consider to be unfavorable.


DETERMINATION OF SUBSCRIPTION PRICE

         The subscription price is $ o per ADS. Our board of directors
determined the per ADS subscription price based upon a number of factors
including:


         o        GFN's commitment to exercise its rights in full valued at $40
                  million;


         o        the historic and current market price of our ADSs;

         o        the difficult market conditions prevailing for the raising of
                  equity capital;

         o        our business prospects;

         o        our operating history;

         o        general conditions in the securities market;

         o        our need for capital;

         o        alternatives available to us for raising capital;

         o        the amount of proceeds desired; and

         o        general economic, business and market conditions.

         The $[__________] per share price should not be considered an
indication of the actual value of our ADSs. You may not be able to sell ADSs
purchased during this offering at a price equal to or greater than $[__________]
per share. We have neither sought, nor obtained, any valuation opinion from
outside financial advisors or investment bankers.

TRANSFERABILITY OF SUBSCRIPTION RIGHTS

         Only you may exercise the subscription privilege. You may not sell,
give away or otherwise transfer the subscription privilege. The rights will
not be listed for trading on any stock exchange.

EXTENSION, WITHDRAWAL AND AMENDMENT


         We have the option of extending the period for exercising your rights,
although we do not intend to do so at this time. We also reserve the right to
withdraw or terminate this offering at any time for any reason. In the event
that this offering is withdrawn or terminated, all funds received from
subscriptions



                                      -30-
<Page>


will be returned promptly. We will not pay interest on any returned funds. We
will notify shareholders if we extend, withdraw or terminate this offering by
issuing a press release and filing that press release with the Securities and
Exchange Commission as an exhibit to a Form 6-K.


         We reserve the right to amend the terms of this offering. If we make an
amendment that we consider significant, we will


         o        mail notice of the amendment to all shareholders of record as
                  of the record date,



         o        extend the expiration date by at least ten days and



         o        offer all subscribers no less than ten days to revoke any
                  subscription already submitted.


o        The extension of the expiration date will not, in and of itself, be
         treated as a significant amendment for these purposes.


MAILING OF  SUBSCRIPTION CERTIFICATES AND RECORD HOLDERS



         We are sending a subscription certificate to each record holder along
with this prospectus and related instructions to evidence the rights. In order
to exercise rights, you must fill out and sign the subscription certificate and
timely deliver it with full payment for the shares to be purchased. Only the
holders of record of our ADSs, Class A common stock and Class B stock as of the
close of business as of the record date may exercise rights. You are a record
holder for this purpose only, in the case of holders of ADSs, if your name is
registered as a holder with our depositary, The Bank of New York, as of the
record date.



         A depository bank, trust company or securities broker or dealer which
is a record holder for more than one beneficial owner of shares may divide or
consolidate subscription certificates to represent shares held as of the record
date by their beneficial owners, upon proper showing to the subscription agent.


         If you own shares held in a brokerage, bank or other custodial or
nominee account, in order to exercise your rights you must promptly send the
proper instruction form to the person holding your shares. Your broker, dealer,
depository or custodian bank or other person holding your shares is the record
holder of your shares and will have to act on your behalf in order for you to
exercise your rights. We have asked your broker, dealer or other nominee holders
of our shares to contact the beneficial owners to obtain instructions concerning
rights the beneficial owners it represents are entitled to exercise.

FOREIGN AND UNKNOWN ADDRESSES


         We are not mailing subscription certificates to shareholders whose
addresses are outside the United States or who have an APO or FPO address. In
those cases, the subscription certificates will be held by the subscription
agent for those shareholders. To exercise their rights, these shareholders must
notify the subscription agent prior to 11:00 a.m., New York City time, on the
third business day prior to the expiration date.


RIGHT TO BLOCK EXERCISE DUE TO REGULATORY ISSUES


         We reserve the right to refuse the exercise of rights by any holder of
rights who would, in our opinion, be required to obtain prior clearance or
approval from any Dominican or U.S. state or federal or regulatory authorities
for the exercise of rights or ownership of additional shares if, at the
expiration date, this clearance or approval has not been obtained. We are not
undertaking to pay any expenses incurred in seeking such clearance or approval.




                                      -31-
<Page>

         We are not offering or selling, or soliciting any purchase of, shares
in any state or other jurisdiction in which this offering is not permitted. We
reserve the right to delay the commencement of this offering in certain states
or other jurisdictions if necessary to comply with local laws. However, we may
elect not to offer rights to residents of any state or other jurisdiction whose
law would require a change in this offering in order to carry out this offering
in such state or jurisdiction.

PROCEDURES TO EXERCISE RIGHTS


         Please do not send subscription certificates or related forms to us.
Please send the properly completed and executed form of subscription certificate
with full payment to the subscription agent for this offering, The Bank of New
York.



         You should read carefully the subscription certificate and related
instructions and forms which accompany this prospectus. You should call
1(800) 628-8510 or collect at 1(212) 269-5550, the information agent for this
offering, at the address and telephone number listed below under the caption
"This Offering - Questions and Assistance Concerning the Rights" promptly with
any questions you may have.



         You may exercise your rights by delivering to the subscription agent,
at the address specified below and in the instructions accompanying this
prospectus, on or prior to the expiration date:



         Properly completed and executed subscription certificate(s) which
evidence your rights. See "The Offering - Delivery of Subscription Certificate"
below for instructions on where to send these.


         o        Any required signature guarantees.


         o        Payment in full of the subscription price for each newly
                  issued ADS you wish to purchase under the subscription
                  privilege and the oversubscription privilege. See "This
                  Offering - Required Forms of Payment of Subscription Price"
                  below for payment instructions.


REQUIRED FORMS OF PAYMENT OF SUBSCRIPTION PRICE

         The subscription price is $[__________] per ADS subscribed for, payable
in cash. All payments must be cleared on or before the expiration date.


         If you exercise any rights, you must deliver to the subscription agent
full payment in the form of a personal check, certified or cashier's check or
bank draft drawn upon a U.S. bank, or a U.S. postal money order, payable to The
Bank of New York, subscription agent.



         In order for you to timely exercise your rights, the subscription agent
must actually receive the subscription price before the expiration date.



         Funds paid by uncertified personal check may take at least five
business days to clear. Accordingly, if you pay the subscription price by means
of uncertified personal check, you should make payment sufficiently in advance
of the expiration date to ensure that your check actually clears and the payment
is received before such date. We are not responsible for any delay in payment by
you and suggest that you consider payment by means of certified or cashier's
check or bank draft drawn upon a U.S. bank, or a U.S. postal money order.



DELIVERY OF SUBSCRIPTION  CERTIFICATES



         All subscription certificates, payments of the subscription price and
nominee holder certifications and DTC participant oversubscription exercise
forms, to the extent applicable to your exercise of rights, must be delivered to
the subscription agent, The Bank of New York, as follows:

</Table>


INCOMPLETE FORMS; INSUFFICIENT PAYMENT


         If you do not indicate on your subscription certificate the number of
rights being exercised, or do not forward sufficient payment for the number of
rights that you indicate are being exercised, then we will accept the
subscription forms and payment only for the maximum number of rights that may be
exercised based on the actual payment delivered. We will make this determination
as follows: (1) you will be deemed to have exercised your basic subscription
privilege to the full extent of the payment received, and (2) if any funds
remain, you will be deemed to have exercised your oversubscription privilege to
the extent of the remaining funds. We will return any payment not applied to the
purchase of ADSs under this offering promptly. Interest will not be payable on
amounts refunded.


PROHIBITION ON FRACTIONAL SHARES


         Each right entitles you to purchase one ADS at the subscription price.
We will accept any inadvertent subscription indicating a purchase of fractional
ADSs by rounding down to the nearest whole ADS and refunding without interest
any payment received for a fractional ADS promptly.


INSTRUCTIONS TO NOMINEE HOLDERS

         If you are a broker, trustee or depository for securities or other
nominee holder for beneficial owners of our ADSs, we are requesting that you
contact such beneficial owners as soon as possible to obtain instructions and
related certifications concerning their rights. Our request to you is further
explained in the suggested form of letter of instructions from nominee holders
to beneficial owners accompanying this prospectus.


         To the extent so instructed, nominee holders should complete
appropriate subscription certificates on behalf of beneficial owners and, in the
case of any exercise of the oversubscription privilege, the related form of
"Nominee Holder Certification" and submit them on a timely basis to the
subscription agent, The Bank of New York, with the proper payment.



RISK OF LOSS ON DELIVERY OF SUBSCRIPTION  CERTIFICATE FORMS AND PAYMENTS



         Each holder of rights bears all risk of the method of delivery to the
subscription agent of subscription certificates and payments of the subscription
price.



         If subscription certificates and payments are sent by mail, you are
urged to send these by registered mail, properly insured, with return receipt
requested, and to allow a sufficient number of days to ensure delivery to the
subscription agent and clearance of payment prior to the expiration date.




                                      -33-
<Page>


         Because uncertified personal checks may take at least five business
days to clear, you are strongly urged to pay, or arrange for payment, by means
of certified or cashier's check or bank draft drawn upon a U.S. bank, or a U.S.
postal money order.


HOW PROCEDURAL AND OTHER QUESTIONS ARE RESOLVED


         We are entitled to resolve all questions concerning the timeliness,
validity, form and eligibility of any exercise of rights. Our determination of
such questions will be final and binding. We, in our reasonable discretion, may
waive any defect or irregularity, or permit a defect or irregularity to be
corrected within such time as we may determine, or reject the purported exercise
of any right because of any defect or irregularity.



         Subscription certificates will not be considered received or accepted
until all irregularities have been waived or cured within such time as we
determine in our reasonable discretion. Neither we nor the subscription agent
have any duty to give notification of any defect or irregularity in connection
with the submission of subscription certificates or any other required document.
Neither we nor the subscription agent will incur any liability for failure to
give such notification.


         We reserve the right to reject any exercise of rights if the exercise
does not comply with the terms of this offering or is not in proper form or if
the exercise of rights would be unlawful or materially burdensome.

ISSUANCE OF CERTIFICATES


         Certificates for ADSs purchased in this offering will be issued as soon
as practicable after the expiration date. The subscription agent will deliver
subscription payments to us only after consummation of this offering and the
issuance of certificates to our shareholders that exercised rights. Unless you
instruct otherwise in your subscription certificate form, ADSs purchased by the
exercise of rights will be registered in the name of the person exercising the
rights.


SHARES OF CLASS A COMMON STOCK OUTSTANDING AFTER THE RIGHTS OFFERING


         Assuming we issue all of the ADSs, each of which represents one
share of Class A common stock, offered in the rights offering, approximately
[__________] shares of Class A common stock will be issued and outstanding.
This would represent a [_____]% increase in the number of outstanding shares
of Class A common stock as of the date of this prospectus. Even if no other
shareholders exercise their subscription rights, GFN has committed to
purchase a total of approximately [____] shares of Class A common stock from us
in the rights offering, in which case we will have [___] shares of Class A
Common Stock outstanding after the rights offering. IF YOU DO NOT EXERCISE
YOUR SUBSCRIPTION PRIVILEGE, THE PERCENTAGE OF OUR CLASS A COMMON STOCK THAT
YOU HOLD WILL DECREASE.


FEES AND EXPENSES

         We will pay all fees charged by the subscription agent. You are
responsible for paying any other commissions, fees, taxes or other expenses
incurred in connection with the exercise of the subscription rights. Neither we
nor the subscription agent will pay these expenses.


         We will pay the issuance fees to the depositary, which would be in the
amount of US$5.00 per 100 ADSs issued.


SUBSCRIPTION AGENT


         We have appointed The Bank of New York as subscription agent for the
rights offering. The subscription agent's address for packages sent by mail or
overnight delivery is:

estimate will total $[_______]. We have also agreed to indemnify the
subscription agent from any liability, which it may incur in connection with the
rights offering.

CERTIFICATE AND PAYMENT BY MAIL, WE RECOMMEND THAT YOU USE REGISTERED MAIL,

UNCERTIFIED PERSONAL CHECKS MAY TAKE AT LEAST FIVE BUSINESS DAYS TO CLEAR, WE
STRONGLY URGE YOU TO PAY, OR ARRANGE FOR PAYMENT, BY MEANS OF CERTIFIED OR
CASHIER'S CHECK OR BANK DRAFT DRAWN UPON A U.S. BANK, OR A U.S. POSTAL MONEY
ORDER.

                   DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS

AMERICAN DEPOSITARY RECEIPTS


                                      -35-
<Page>


         The Bank of New York will issue the American Depositary Receipts or
ADRs evidencing ADSs. Each ADS represents one share of Class A common stock. We
will deposit the shares of Class A common stock (or the right to such shares) to
be issued in this offering with the New York office of The Bank of New York
which we refer to as the custodian. Each ADR will also represent securities,
cash or other property deposited, from time to time, with The Bank of New York
but not distributed to ADR holders. The Bank of New York's Corporate Trust
office is located at 101 Barclay Street, New York, NY 10286, and its principal
executive office is located at One Wall Street, NY, NY 10286 (temporarily
located at One Wall Street, NY, NY 10286).


         You may hold ADRs either directly or indirectly through your broker or
other financial institution. If you hold ADRs directly, you are an ADR holder.
If you hold the ADRs indirectly, you must rely on the procedures of your broker
or other financial institution to assert the rights of ADR holders described in
this section. You should consult with your broker or financial institution to
find out what those procedures are.

         Because The Bank of New York actually holds the shares, you must rely
on it to exercise the rights of a shareholder. Our obligations and the
obligations of The Bank of New York are set out in an agreement among TRICOM,
The Bank of New York and you, as an ADR holder. The agreement and the ADRs are
generally governed by New York law.


         The following is a summary of the agreement. We encourage you to read
the entire agreement and the ADR. Directions on how to obtain copies of these
are provided in the section entitled "Where You Can Find More Information."


SHARE DIVIDENDS AND OTHER DISTRIBUTIONS

         The Bank of New York has agreed to pay to you the cash dividends or
other distributions it receives on shares or other deposited securities after
deducting its fees and expenses. You will receive these distributions in
proportion to the number of shares your ADRs represent.

         CASH. The Bank of New York will convert any cash dividend or other cash
distribution we pay on the shares into U.S. dollars, if it can do so on a
reasonable basis, and, subject to Dominican Republic law, can transfer the U.S.
dollars to the United States. If that is not possible or if any approval from
the Dominican Republic government is needed and cannot be obtained, the
agreement allows The Bank of New York to distribute the Dominican pesos only to
those ADR holders to whom it is possible to do so. It will hold the Dominican
pesos it cannot convert for the account of the ADR holders who have not been
paid. It will not invest the Dominican pesos and it will not be liable for the
interest.

         Before making a distribution, any withholding taxes that must be paid
under Dominican Republic law will be deducted. The Bank of New York will
distribute only whole U.S. dollars and cents and will round fractional cents to
the nearest whole cent. If the exchange rates fluctuate during a time when The
Bank of New York cannot convert the Dominican pesos, you may lose some or all of
the value of the distribution.

         SHARES. The Bank of New York may distribute new ADRs representing any
shares we may distribute as a dividend or free distribution, if we furnish it
promptly with satisfactory evidence that it is legal to do so. The Bank of New
York will only distribute whole ADRs. It will sell shares which would require it
to use a fractional ADR and distribute the net proceeds in the same way as it
does with cash. If The Bank of New York does not distribute additional ADRs,
each ADR will also represent the new shares.

         RIGHTS TO RECEIVE ADDITIONAL SHARES. If we offer holders of our shares
any rights to subscribe for additional shares or any other rights, The Bank of
New York may make these rights available to you. We must first instruct The Bank
of New York to do so and furnish it with satisfactory evidence that it is legal



                                      -36-
<Page>

to do so. If we do not furnish this evidence and/or give these instructions, and
The Bank of New York decides it is practical to sell the rights, The Bank of New
York will sell the rights and distribute the proceeds, in the same way as it
does with cash. The Bank of New York may allow rights that are not distributed
or sold to lapse. In that case, you will receive no value for them.

         If The Bank of New York makes rights available to you, upon instruction
from you, it will exercise the rights and purchase the shares on your behalf.
The Bank of New York will then deposit the shares and issue ADRs to you. It will
only exercise rights if you pay it the exercise price and any other charges the
rights require you to pay.

         U.S. securities laws may restrict the sale, deposit, cancellation and
transfer of the ADRs issued after exercise of rights. For example, you may not
be able to trade the ADRs freely in the United States. In this case, The Bank of
New York may issue the ADRs under a separate restricted deposit agreement which
will contain the same provisions as the agreement, except for the changes needed
to put the restrictions in place.

         OTHER DISTRIBUTIONS. The Bank of New York will send to you anything
else we distribute on deposited securities by any means it thinks is legal, fair
and practical. If it cannot make the distribution in that way, The Bank of New
York has a choice. It may decide to sell what we distributed and distribute the
net proceeds in the same way as it does with cash or it may decide to hold what
we distributed, in which case the ADRs will also represent the newly distributed
property.

         The Bank of New York is not responsible if it decides that it is
unlawful or impractical to make a distribution available to any ADR holders. We
have no obligation to register ADRs, shares, rights or other securities under
the Securities Act of 1933. We also have no obligation to take any other action
to permit the distribution of ADRs, shares, rights or anything else to ADR
holders. This means that you may not receive the distribution we make on our
shares or any value for them if it is illegal or impractical for us to make them
available to you.

DEPOSIT, WITHDRAWAL AND CANCELLATION

         The Bank of New York will issue ADRs if you or your broker deposit
shares or evidence of rights to receive shares with it. Upon payment of its fees
and expenses and of any taxes or charges, such as stamp taxes or stock transfer
taxes or fees, The Bank of New York will register the appropriate number of ADRs
in the names you request and will deliver the ADRs at its Corporate Trust office
to the persons you request.

         You may turn in your ADRs at The Bank of New York's Corporate Trust
office. Upon payment of its fees and expenses and of any taxes or charges, such
as stamp taxes or stock transfer taxes or fees, The Bank of New York will
deliver (1) the underlying shares to an account designated by you and (2) any
other deposited securities underlying the ADR at the office of the custodian.
Or, at your request, risk and expense, The Bank of New York will deliver the
deposited securities at its Corporate Trust office.

VOTING RIGHTS

         You may instruct The Bank of New York to vote the shares underlying
your ADRs but only if we ask The Bank of New York to ask for your instructions.
Otherwise, you won't be able to exercise your right to vote unless you withdraw
the shares. However, you may not know about the meeting enough in advance to
withdraw the shares.

         If we ask for your instructions, The Bank of New York will notify you
of the upcoming vote and arrange to deliver our voting materials to you. The
materials will (1) describe the matters to be voted on and (2) explain how you,
on a certain date, may instruct The Bank of New York to vote the shares or other
deposited securities underlying your ADRs as you direct. For instructions to be
valid, The Bank of


                                      -37-
<Page>

New York must receive them on or before the date specified. The Bank of New York
will try, as far as practical, subject to Dominican Republic law and the
provisions of our by-laws, to vote or to have its agents vote the shares or
other deposited securities as you instruct. The Bank of New York will only vote
or attempt to vote as you instruct.

         We cannot assure you that you will receive the voting materials in time
to ensure that you can instruct The Bank of New York to vote your shares. In
addition, The Bank of New York and its agents are not responsible for failing to
carry out voting instructions or for the manner of carrying out voting
instructions. This means that you may not be able to exercise your right to vote
and there may be nothing you can do if your shares are not voted as you
requested.

</Table>


 PAYMENT OF TAXES


         You will be responsible for any taxes or other governmental charges
payable on your ADRs or on the deposited securities underlying your ADRs. The
Bank of New York may refuse to transfer your ADRs or allow you to withdraw the
deposited securities underlying your ADRs until such taxes or other charges are
paid. It may apply payments owed to you or sell deposited securities underlying
your ADRs to pay any taxes owed and you will remain liable for any deficiency.
If it sells deposited securities, it will, if appropriate, reduce the number of
ADRs to reflect the sale and pay to you any proceeds, or send to you any
property, remaining after it has paid the taxes.

RECLASSIFICATIONS, RECAPITALIZATIONS AND MERGERS

         If we (1) change the nominal or par value of our shares, (2)
reclassify, split up or consolidate any of the deposited securities, (3)
distribute securities on the shares that are not distributed to you, or (4)
recapitalize, reorganize, merge, liquidate, sell all or substantially all of our
assets, or take any similar action, then the cash, shares or other securities
received by The Bank of New York will become deposited securities. Each ADR will
automatically represent its equal share of the new deposited securities unless


                                      -38-
<Page>

additional ADRs are delivered pursuant to the following sentence. The Bank of
New York may, and will if we ask it to, issue new ADRs or ask you to surrender
your outstanding ADRs in exchange for new ADRs, identifying the new deposited
securities.

AMENDMENT AND TERMINATION

         We may agree with The Bank of New York to amend the agreement and the
ADRs without your consent for any reason. If the amendment adds or increases
fees or charges, except for taxes and other governmental charges or registration
fees, cable, telex or facsimile transmission costs, delivery costs or other such
expenses, or prejudices an important right of ADR holders, it will only become
effective 30 days after The Bank of New York notifies you of the amendment. At
the time an amendment becomes effective, you are considered, by continuing to
hold your ADR, to agree to the amendment and to be bound by the ADRs and the
agreement is amended.

         The Bank of New York will terminate the agreement if we ask it to do
so. The Bank of New York may also terminate the agreement if The Bank of New
York has told us that it would like to resign and we have not appointed a new
depositary bank within 90 days. In both cases, The Bank of New York must notify
you at least 90 days before termination.

         After termination, The Bank of New York and its agents will be required
to do only the following under the agreement


         o        advise you that the agreement is terminated and


         o        collect distributions on the deposited securities and deliver
                  shares and other deposited securities upon cancellation of
                  ADRs.

                  o At any time after the expiration of one year after the date
     of termination, The Bank of New York may sell any remaining deposited
     securities by public or private sale. After that, The Bank of New York
     will hold the proceeds of the sale, as well as any other cash it is
     holding under the agreement for the pro rata benefit of the ADR holders
     that have not surrendered their ADRs. It will not invest the money and
     will have no liability for interest. The Bank of New York's only
     obligations will be to account for the proceeds of the sale and other
     cash. After termination, our only obligations will be with respect to
     indemnification and to pay certain amounts to The Bank of New York.

INSPECTION OF TRANSFER BOOKS

         The Bank of New York will maintain at its transfer office in the
Borough of Manhattan, the City of New York, facilities for the execution and
delivery, registration of transfer, combination or split-up of ADRs and a
register for the registration of ADRs and the registration of the transfer of
ADRs that at reasonable times will be open for inspection by us and the holders
of ADRs, provided that such inspection shall not be for the purpose of
communication with holders of ADRs in the interest of a business or object other
than our business or a matter related to the ADRs.

LIMITATIONS ON OBLIGATIONS AND LIABILITY TO ADR HOLDERS

         The agreement expressly limits our obligations and the obligations of
The Bank of New York, and it limits our liability and the liability of The Bank
of New York. TRICOM and The Bank of New York:

         o        are only obligated to take the actions specifically set forth
                  in the agreement without negligence or bad faith;



                                      -39-
<Page>

         o        are not liable if either is prevented or delayed by law or
                  circumstances beyond their control from performing their
                  obligations under the agreement;

         o        are not liable if either exercises discretion permitted under
                  the agreement;

         o        have no obligation to become involved in a lawsuit or other
                  proceeding related to the ADRs or the agreement on your behalf
                  or on behalf of any other party; and

         o        may rely upon any documents they believe in good faith to be
                  genuine and to have been signed or presented by the proper
                  party.


         NONE OF THESE LIMITATIONS AFFECTS INVESTOR RIGHTS UNDER THE UNITED
STATES FEDERAL SECURITIES LAWS.


         In the agreement, TRICOM and The Bank of New York agree to indemnify
each other under certain circumstances.

REQUIREMENTS FOR DEPOSITARY ACTIONS

         Before The Bank of New York will issue or register transfer of an ADR,
make a distribution on an ADR, or process the withdrawal of any shares, The Bank
of New York may require:

         o        payment of stock transfer or other taxes or other governmental
                  charges and transfer or registration fees charged by third
                  parties for the transfer of any shares or other deposited
                  securities;

         o        production of satisfactory proof of the identity and
                  genuineness of any signature or other information it deems
                  necessary; and

         o        compliance with regulations it may establish, from time to
                  time, consistent with the agreement, including presentation of
                  transfer documents.

         The Bank of New York may refuse to deliver, transfer, or register
transfers of ADRs generally when our books or the books of The Bank of New York
are closed, or at any time if we or The Bank of New York thinks it advisable to
do so.

         You have the right to cancel your ADRs and withdraw the underlying
shares at any time except:

         o        when temporary delays arise because: (1) The Bank of New York
                  or TRICOM has closed its transfer books; (2) the transfer of
                  shares is blocked to permit voting at a shareholders' meeting;
                  or (3) TRICOM is paying a dividend on the shares;

         o        when you or other ADR holders seeking to withdraw shares owe
                  money to pay fees, taxes and similar charges; or

         o        when it is necessary to prohibit withdrawals in order to
                  comply with any laws or governmental regulations that apply
                  to ADRs or to the withdrawal of shares or other deposited
                  securities.

         This right of withdrawal may not be limited by any other provision of
the agreement.

PRE-RELEASE OF ADRS

         In certain circumstances, subject to the provisions of the agreement,
The Bank of New York may issue ADRs before deposit of the underlying shares.
This is called a pre-release of the ADR. The Bank of New York may also deliver
shares upon cancellation of pre-released ADRs (even if the ADRs are


                                      -40-
<Page>

canceled before the pre-release transaction has been closed out). A pre-release
is closed out as soon as the underlying shares are delivered to The Bank of New
York. The Bank of New York may receive ADRs instead of shares to close out a
pre-release. The Bank of New York may pre-release ADRs only under the following
conditions:


         o        before or at the time of the pre-release, the person to whom
                  the pre-release is being made must represent to The Bank of
                  New York in writing that it or its customer owns the shares or
                  ADRs to be deposited;



         o        the pre-release must be fully collateralized with cash or
                  other collateral that The Bank of New York considers
                  appropriate; and



         o        The Bank of New York must be able to close out the pre-release
                  on not more than five business days' notice.



o        In addition, The Bank of New York will limit the number of ADRs that
         may be outstanding at any time as a result of pre-release, although The
         Bank of New York may disregard the limit from time to time, if it
         thinks it is appropriate to do so.



                    TAX CONSIDERATIONS OF THE RIGHTS OFFERING



DOMINICAN REPUBLIC TAX CONSIDERATIONS



         In the opinion of our Dominican law firm, Pellerano & Herrera, the
discussion below sets forth the material Dominican Republic income tax
consequences of this offering to the holders of our ADSs, Class A common stock
and Class B stock with respect to the distribution of the rights, which for the
purposes of this tax discussion includes oversubscription rights, to them and of
the exercise of such rights.



         ISSUANCE OF RIGHTS



         You will not recognize taxable income for Dominican income tax purposes
upon distribution of the rights.



         LAPSE OF THE RIGHTS



         If you own shares of Class A common stock and allow your rights
received to lapse, no gain or loss will be recognized and the basis in the
shares upon which you received a distribution of the rights will be the same as
it was immediately prior to the distribution of the rights.



         EXERCISE OF RIGHTS; SALE OF SHARES



         You will not recognize any gain or loss upon the exercise of your
rights. The basis of the shares acquired through your exercise of the rights
will be equal to the subscription price paid for the shares acquired through
exercise of the rights. If you sell your shares acquired through the exercise of
the rights, you may recognize gain or loss in an amount equal to the difference
between the amount realized on the sale and your basis in the shares, adjusted
for inflation. Regulations for the application of the Dominican Tax Code clarify
how the tax basis is to be calculated and also provide how the inflation
adjustment is to be applied.



UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS


                                      -41-
<Page>


         In the opinion of our United States law firm, Piper Marbury Rudnick &
Wolfe LLP, the discussion below sets forth the material United States income tax
consequences of this offering to the holders of our ADSs, Class A common stock
and Class B stock with respect to the distribution of the rights, which for the
purposes of this tax discussion includes oversubscription rights, to them and of
the exercise of such rights. The summary is based on the Internal Revenue Code
of 1986, as amended, which we refer to as the Code, the Treasury regulations
promulgated under the Code, judicial authority and current administrative rules
and practice, all of which are subject to change on a prospective or retroactive
basis.


         The tax consequences of this offering under state, local and foreign
law are not discussed. The consequences of this offering with respect to any
taxes other than income taxes are not discussed. Moreover, special
considerations not described in this summary may apply to some taxpayers or some
types of taxpayers, including financial institutions, broker-dealers, nominee
holders of our shares, life insurance companies, tax- exempt organizations and
foreign taxpayers. The discussion is limited to those who have held the ADSs,
Class A common stock and Class B stock, and will hold the rights and any shares
acquired upon the exercise of the rights, as capital assets (generally, property
held for investment) within the meaning of Section 1221 of the Code.

         WE URGE STOCKHOLDERS TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO
THE PARTICULAR FEDERAL INCOME OR OTHER TAX CONSEQUENCES TO THEM OF THE OFFERING,
AS WELL AS THE TAX CONSEQUENCES UNDER STATE, LOCAL AND FOREIGN LAW AND THE
POSSIBLE EFFECTS OF CHANGES IN TAX LAWS.

         ISSUANCE OF RIGHTS

         You will not recognize taxable income for federal income tax purposes
upon distribution of the rights.


         STOCKHOLDER BASIS AND  HOLDING PERIOD OF THE RIGHTS



         As a result of receiving the distribution of rights, you must generally
allocate the basis of your ADSs and Class A common stock (treating them as one
class of stock) or Class B stock between such stock and the rights in proportion
to their respective fair market values on the date of issuance. For example,
assume that you own Class A common stock with a basis of $80 and a fair market
value of $100 and you are issued rights to acquire new shares of Class A common
stock with a fair market value of $20. After the issuance, you will have a basis
of $66.67 in your Class A common stock and $13.33 in your rights. If the rights
are subsequently exercised, the basis of the new stock acquired will be equal to
the subscription price paid for the new stock plus your basis in the rights
exercised. If the rights are sold prior to exercise, the gain (or loss) will be
equal to the amount realized on the sale less your basis in the rights.



         If the fair market value of your rights on the date of issuance is less
than 15% of the fair market value of the ADSs and Class A common stock or Class
B stock you hold on the date of issuance, then your basis in the rights will be
zero. In such a case, you may make an irrevocable election on your federal
income tax return for the year relating to the date of issuance to allocate the
basis of your ADSs and Class A common stock or Class B stock between such stock
and the rights in proportion to their respective fair market values on the date
of issuance in the manner set forth in the prior paragraph. An election to
allocate basis to the rights must be in the form of a statement attached to your
income tax return for the year in which the rights were received. If you make
such an election, you must retain a copy of the election, and of the tax return
with which it was filed, in order to substantiate the basis allocated to the
rights. If such an election is not made, the basis of the new stock acquired
will be equal to the subscription price paid. If such an election is not made
and the rights are sold prior to their exercise, the gain will be equal to the
amount realized on the sale.




                                      -42-
<Page>

         Your holding period with respect to the rights will include your
holding period for the ADSs, Class A common stock or Class B stock with respect
to which the rights were distributed.

         LAPSE OF THE RIGHTS

         If you allow your rights received to lapse, no gain or loss will be
recognized and the basis in the shares upon which you received a distribution of
the rights will be the same as it was immediately prior to the distribution of
the rights.

         EXERCISE OF THE RIGHTS; BASIS AND HOLDING PERIOD OF THE COMMON STOCK

         You will not recognize any gain or loss upon the exercise of your
rights. The basis of the shares acquired through your exercise of the rights
will be equal to the sum of the subscription price paid for the shares acquired
through exercise of the rights and your basis in the rights, if any. The holding
period for the shares acquired through exercise of the rights will begin on the
date the rights are exercised.


         For example, assume you hold Class A common stock for a period of two
years and at the end of such two year period, an issuance of rights to acquire
new shares of Class A common stock is made to you on your Class A common stock.
Immediately after the issuance of the rights, your holding period in the rights
will be two years (i.e., the rights will also be a long-term capital asset in
your hands). Assume further that $10 of basis is allocated to the rights and the
subscription price for the new Class A common stock is $100. Your basis in the
new Class A common stock will be $110 (i.e., your $10 basis in your rights plus
the $100 subscription price paid to exercise the rights) on the date you
exercise your rights. The holding period for the new Class A common stock will
then begin on the day the rights are exercised.


         SALE OF SHARES

         If you sell your shares acquired through the exercise of the rights,
you will recognize gain or loss in an amount equal to the difference between the
amount realized on the sale and your basis in the shares, which will include the
exercise price. If you hold the shares as a capital asset, gain or loss on the
sale will be long-term or short-term capital gain or loss, depending on whether
you have held the shares for more than one year beginning on the date of
exercise of the rights.

                       TAX CONSIDERATIONS OF OWNING SHARES

DOMINICAN REPUBLIC TAX CONSIDERATIONS


         The following discussion summarizes the material Dominican Republic
income tax consequences of an investment in the ADRs, ADSs or shares of Class A
common stock by a person who is neither domiciled in nor a resident of the
Dominican Republic for tax purposes and who holds such ADRs, ADSs or shares of
Class A common stock for investment purposes and not for purposes of a trade or
business. In the opinion of our Dominican law firm, Pellerano & Herrera, the
discussion sets forth the material Dominican Republic consequences of such an
investment. The discussion is not intended as tax advice to any particular
investor.



         Under our 1996 concession agreement with the Dominican government which
grants to us our right to operate as a telecommunications provider, dividends
and interest paid to any of our shareholders, bondholders or other investors are
exempt from Dominican income tax. Under Dominican tax law, the term "dividends"
refers to any distribution of profits of a company to its shareholders. Thus,
under the concession agreement, any dividend or distribution paid by us with
respect to the Class A common stock will not be subject to Dominican income tax.



                                      -43-
<Page>


         Our concession agreement has not yet been approved by the Dominican
Congress, but was duly executed by the Dominican Executive Branch, making the
concession itself valid and binding on the Dominican government under our laws.
Provisions in our concession agreement providing preferential tax treatment for
TRICOM and its shareholders still need to be submitted to and approved by the
Dominican Congress to be binding under the Dominican Constitution. At the time
our concession agreement was executed, it was not submitted to the Dominican
Congress for approval for political reasons. Our concession agreement, along
with the concession agreements of most of TRICOM's competitors in the
telecommunications business, was not submitted to the Dominican Congress because
the Dominican Congress was greatly divided at that time and the Dominican
Executive Branch did not control a majority of the Congress. However, the tax
provisions contained in these concession agreements, along with other concession
agreements in other areas, have been completely followed and complied with by
our Dominican Tax Administration.



         Until our concession agreement is approved by the Dominican Congress,
however, cash dividends and other distributions paid by us with respect to ADSs
or shares of Class A common stock held by any holder could be subject to a 25%
withholding tax, which would be required to be withheld by us and paid to the
Dominican tax administration at the time a cash dividend or other distribution
is paid. Such tax withheld may not be a creditable foreign tax in determining
the U.S. tax liability of such holder. We are not aware of any plans of the
Dominican government to submit our 1996 concession agreement for approval to the
Dominican Congress.



         Our concession agreement does not specifically address whether capital
gains taxes will apply to sales of ADSs in the Dominican Republic. However, it
states that the transfer or sale of our shares of any type will be exempt from
Dominican income tax. Under the principles of territoriality underlying the
Dominican constitution, gain from the sale or exchange of ADRs evidencing the
ADSs by a foreign holder outside of the Dominican Republic would not be subject
to taxation by the Dominican tax authority even if our 1996 concession agreement
were not applicable to gains on the transfer or sale of ADSs.



         Until our 1996 concession agreement is approved by the Dominican
Congress, the Dominican government could require payment of capital gains tax on
gain recognized on the sale or exchange in the Dominican Republic of shares of
Class A common stock (as distinguished from sales or exchanges of ADSs). The
capital gains tax was instituted in the Dominican Republic only in 1992 and was
later modified by regulations in 1998 as part of major tax reform legislation.
Under present law, the capital gains tax rate is identical to the regular income
tax rate of the person or entity that earned such gain; there is no preferential
rate. Thus, a corporation, whether based in the Dominican Republic or not,
selling shares of Class A common stock in the Dominican Republic would be
required to pay the corporate income tax of 25% on any gain from a sale or
exchange of such shares. An individual, whether a resident of the Dominican
Republic or not, also would have to pay income tax at the applicable individual
rate, as set forth below, on gain from the sale of shares of Class A common
stock in the Dominican Republic. The individual income tax rates applicable in
the Dominican Republic since January 1, 2001 are as follows:

If Taxable Income is:                                        The Tax is:
- -----------------------------------------------------        -----------
                                                          
Not over RD$120,000.00                                       0.
Over RD$120,000.01 but not over RD$200,000.00                15% of taxable income over RD$120,000.01.
Over RD$200,000.01 but not over RD$300,000.00                RD$12,000.00 plus 20% of the excess over
                                                                 RD$200,000.01.
Over RD$300,000.01                                           RD$32,000.00 plus 25% of the excess over
                                                                 RD$300,000.01.

         The amount of gain on which the capital gains tax is assessed is equal
to the sale or transfer price (i.e., amount realized on the sale or transfer)
minus the acquisition price, adjusted for inflation.

<Page>


Regulations for the application of the Dominican Tax Code clarify how the tax
basis is to be calculated and also provide how the inflation adjustment is to be
applied.


         There is no income tax treaty in force between the Dominican Republic
and the United States.

         There are no Dominican inheritance or succession taxes applicable to
the ownership, transfer or disposition of ADSs by a foreign holder not domiciled
in the Dominican Republic at the moment of death. It is unclear whether
Dominican gift taxes would apply to the transfer or other disposition by gift of
shares of Class A common stock by a non-resident foreign holder; however, ADSs
or ADRs are not subject to Dominican gift taxes. There are no Dominican stamp,
issue, registration or similar taxes or duties payable by holders of ADSs or
shares of Class A common stock.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS


         In the opinion of our United States law firm, Piper Marbury Rudnick &
Wolfe LLP, the discussion below sets forth the material United States federal
income tax consequences of an investment in the ADSs. This discussion is based
upon United States federal income tax laws and regulations presently in force
and such authorities may be repealed, revoked or modified, possibly with
retroactive effect, so as to result in United States federal income consequences
different from those discussed below.


         The discussion is not a full description of all tax considerations that
may be relevant to a decision to purchase ADSs or to the holding or disposition
of such instruments. In particular, the discussion is directed only to U.S.
holders that will hold ADSs as capital assets and that have the United States
dollar as their functional currency. It does not address the tax treatment of
U.S. holders that are subject to special tax rules, including banks, securities
dealers, insurance companies, tax-exempt entities, holders who hold ADSs as part
of a hedging, straddle or conversion transaction and holders of 10% or more of
the total combined voting power of our voting shares. Prospective purchasers
should consult their tax advisors about the federal, state, local and foreign
tax consequences to them of the purchase, ownership and disposition of ADSs.

         U.S. HOLDER

         "U.S. holder" means a beneficial owner of ADSs that is:

         (1)      a United States citizen or resident,

         (2)      a corporation, partnership or other entity created or
                  organized under the laws of the United States or any State or
                  any political subdivision thereof,

         (3)      an estate the income of which is subject to United States
                  federal income taxation regardless of its source, or

         (4)      any trust if both:

                  o        A COURT WITHIN THE UNITED STATES IS ABLE TO EXERCISE
                           PRIMARY SUPERVISION OVER THE ADMINISTRATION OF THE
                           TRUST; AND

                  o        one or more United States persons have the authority
                           to control all substantial decisions of the trust as
                           described in Section 7701(a)(30) of the Code.

         If the obligations contemplated by the deposit agreement are performed
in accordance with its terms, holders of ADSs will be treated for United States
federal income tax purposes as the owners of the shares of Class A common stock
represented by ADSs.



                                      -45-
<Page>

      CASH AND OTHER DISTRIBUTIONS

         Distributions made by us with respect to ADSs (other than distributions
in liquidation and certain distributions in redemption of stock) will generally
be taxed as ordinary dividend income to the extent that such distributions do
not exceed our current and accumulated earnings and profits, as determined in
accordance with United States federal income tax principles. Distributions, if
any, in excess of our current and accumulated earnings and profits will
constitute a non-taxable return of capital and will be applied against and will
reduce your tax basis in the ADSs (but not below zero). To the extent that such
distributions exceed your basis in the shares, the excess generally will be
treated as capital gain.

         Dividends generally will be included in your gross income as ordinary
income when the dividends are received by you or the depositary, as applicable.
Dividends paid in Dominican pesos will be included in your gross income as a
United States dollar amount based on the exchange rate in effect on the day of
receipt by you or the depositary, as applicable. Any gain or loss recognized
upon a subsequent sale or conversion of the Dominican pesos into U.S. dollars
will be United States source ordinary income or loss. Dividends will generally
not be eligible for the dividends-received deduction allowed to corporations.

         Dividends generally will be foreign source income for purposes of
determining your foreign tax credit limitation and generally will be "passive"
income. Any Dominican tax withheld on such dividends may not be a creditable
foreign tax in determining your U.S. tax liability. As we have been advised by
our local counsel that we would be permitted to credit the amount withheld
against our Dominican corporate income tax, you might be treated as, in effect,
not paying any Dominican tax.

         CAPITAL GAINS AND LOSSES

         You will recognize capital gain or loss on the sale or other
disposition of ADSs in an amount equal to the difference between the amount
realized for the ADSs over their adjusted tax basis. If you are an individual,
such gain or loss will be taxed at the rate of tax for capital gains provided
you held the ADSs for longer than one year. The deductibility of capital losses
is subject to limitations. You will not recognize gain or loss on any deposits
or withdrawals of shares of Class A common stock in exchange for ADSs. Any gain
you recognize on a sale of ADSs generally will be treated as United States
source income for purposes of determining your foreign tax credit limitation.

         BACKUP WITHHOLDING


         You may be subject to backup withholding at the rate of 31% with
respect to dividends paid on the ADSs or the proceeds of a sale, exchange or
redemption of ADSs unless (1) you are a corporation or come within certain other
exempt categories, and, when required, demonstrate this fact, and (2) provide a
correct taxpayer identification number, certify that you are not subject to
backup withholding and otherwise comply with applicable requirements of the
backup withholding rules. Any amount withheld under these rules will be
creditable against your U.S. federal income tax liability. If you do not provide
a correct taxpayer identification number, you may be subject to penalties
imposed by the U.S. Internal Revenue Service. Currently, the backup withholding
rate is 30.5%, but is scheduled to be reduced to 30% as of January 1, 2002.


                                  LEGAL MATTERS

             The validity of the ADSs is being passed upon for us by Piper
Marbury Rudnick & Wolfe LLP, New York, New York. The validity of the shares of
Class A common stock underlying such ADSs is being passed upon for us by our
Dominican counsel, Pellerano & Herrera, Santo Domingo, Dominican Republic. Piper
Marbury Rudnick & Wolfe LLP may rely, without independent investigation, upon
the opinion of Pellerano & Herrera with respect to matters governed by Dominican
Republic Law.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 8.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         There are no statutory provisions under applicable Dominican law for
the indemnification or insuring of directors against liability.


         Pursuant to Dominican law, shareholders are asked to vote upon the
performance of management at annual shareholders' meetings. The Company's
vigilance officer delivers a report on the financial performance of the Company
and other issues related to management's performance. If the holders of a
majority of the votes entitled to be cast approve management's performance, all
shareholders are deemed to have released the directors and officers from claims
or liability to the Company or its shareholders arising out of actions taken or
any failure to take actions by any of them on behalf of the Company during the
prior fiscal year, with certain exceptions, and shareholders will likely fail in
any suit brought in a Dominican court with respect to such acts or omissions.
Officers and directors may not be released from any claims or liability for
criminal acts, fraud, self-dealing or gross negligence. If the shareholders do
not approve management's performance, the vigilance officer's report may form
the basis of any suit brought by the shareholders against the officers and
directors of the Company.


         Article 48 of the Company's by-laws provides that the Company shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that such person, or a
person of whom he or she is the legal representative, is or was a director,
officer, employee or agent of the Company, or serves or served any other
enterprise as a director, officer, employee or agent at the request of the
Company.

         The Company shall pay any expenses reasonably incurred by a director or
officer in defending any civil, criminal, administrative or investigative
action, suit or proceeding in advance of the final disposition of such action,
suit or proceeding upon receipt of an undertaking by or on behalf of such
director or officer to repay such amount if it shall ultimately be determined
that he or she is not entitled to be indemnified by the Company under Article 48
or otherwise. The Company may, by action of its Board of Directors, provide for
the payment of such expenses incurred by employees and agents of the Company as
it deems appropriate.

ITEM 10. UNDERTAKINGS

(a)      The undersigned hereby undertakes:

(1) To file, during any period in which it offers or sells securities, a
post-effective amendment to this registration statement to:

         (i) Include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933, as amended (the "Securities Act");

         (ii) Reflect in the prospectus any facts or events which, individually
or together, represent a fundamental change in the information in the
registration statement. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or
high end of the estimated maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20% change
in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and

         (iii) Include any additional or changed material information on the
plan of distribution;


                                      II-2
<Page>

         Provided, however, paragraphs (i) and (ii) do not apply if the
information required in a post-effective amendment is incorporated by reference
from periodic reports filed by the Registrant under the Securities Exchange Act
of 1934, as amended.


(2) That, for determining any liability under the Securities Act, to treat
post-effective amendment as a new registration statement of the securities
offered, and the offering of securities at the time to be the initial bona fide
offering.

(3) To file a post-effective amendment to remove from registration any of the
securities that remain unsold at the end of the offering.

(4) To file a post-effective amendment to the registration statement to include
any financial statements required by Item 8.A of Form 20-F at the start of any
delayed offering or throughout a continuous offering.

         Financial statements and information otherwise required by Section
10(a)(3) of the Securities Act need not be furnished, PROVIDED that the
registrant includes in the prospectus, by means of a post-effective amendment,
financial statements required pursuant to this paragraph (4) and other
information necessary to ensure that all other information in the prospectus is
at least as current as the date of those financial statements. Notwithstanding
the foregoing, with respect to registration statements on Form F-3, a
post-effective amendment need not be filed to include financial statements and
information required by Section 10(a)(3) of the Securities Act if such financial
statements and information are contained in periodic reports filed with or
furnished to the Commission by the registrant pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 that are incorporated by reference
in the Form F-3.

(b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

(h) 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 described in Item 8 above, 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. (i)
The undersigned Registrant hereby undertakes that:


(1) for the purpose of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant under Rule 424(b)(1) or (4), or 497(h) under
the Securities Act shall be deemed to be part of this registration statement as
of the time it was declared effective.


(2) for the purpose of determining any liability under the Securities Act, each
post-effective amendment that contains a form of prospectus shall be deemed a
new registration statement relating to the securities

                                      II-3
<Page>
