Securities and Exchange Commission. These securities may not be sold nor may
offers to buy be accepted prior to the time the registration statement becomes

                 SUBJECT TO COMPLETION, DATED FEBRUARY 13, 1998

                               OFFER TO EXCHANGE


               7-3/4% SERIES B SENIOR SUBORDINATED NOTES DUE 2008
                                FOR ANY AND ALL
              OUTSTANDING 7-3/4% SENIOR SUBORDINATED NOTES DUE 2008
                                       OF
                                 MASTEC, INC.



                  THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M.,
              NEW YORK CITY TIME, ON      , 1998, UNLESS EXTENDED


     MasTec, Inc. ("MasTec" or the "Company") hereby offers, upon the terms and
subject to the conditions set forth in this Prospectus and the accompanying
Letter of Transmittal (which together constitute the "Exchange Offer"), to
exchange $1,000 principal amount of 7-3/4% Series B Senior Subordinated Notes
due 2008 of the Company (the "New Notes") for each $1,000 principal amount of
the issued and outstanding 7-3/4% Senior Subordinated Notes due 2008 (the "Old
Notes," and collectively with the New Notes, the "Notes"). Interest on the
Notes is payable semi-annually commencing August 1, 1998 with a final maturity
date of February 1, 2008. As of the date of this Prospectus, $200.0 million
aggregate principal amount of the Old Notes is outstanding. The terms of the
New Notes and the Old Notes are substantially identical in all material
respects, except for certain transfer restrictions and registration rights; and
except that holders of Old Notes are entitled to receive Liquidated Damages (as
defined) if (a) the Company fails to file any of the registration statements
required by the Registration Rights Agreement (as defined) on or before the
date specified for such filing, (b) any of such registration statements is not
declared effective by the Securities and Exchange Commission (the "Commission")
on or prior to the date specified for such effectiveness (the "Effectiveness
Target Date"), (c) the Company fails to consummate the Exchange Offer within 30
business days of the Effectiveness Target Date with respect to the registration
statement of which this Prospectus forms a part (the "Exchange Offer
Registration Statement"), or (d) a shelf registration statement or the Exchange
Offer Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted
Securities (as defined) during the periods specified in the Registration Rights
Agreement (each such event referred to in clauses (a) through (d) above is a
"Registration Default"). In the event of a Registration Default, the Company is
required to pay Liquidated Damages to each holder of Transfer Restricted
Securities with respect to the first 90-day period immediately following the
occurrence of such Registration Default, in an amount equal to $.05 per week
per $1,000 principal amount of Old Notes held by such holder. The amount of the
Liquidated Damages will increase by an additional $.05 per week per $1,000
principal amount of Old Notes with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum amount of
Liquidated Damages of $.20 per week per $1,000 principal amount of Old Notes.
Following the cure of all Registration Defaults, the accrual of Liquidated
Damages will cease. See "Description of Notes--Registration Rights; Liquidated
Damages."


                         (Continued on following page)



SEE "RISK FACTORS" BEGINNING ON PAGE 9 FOR A DISCUSSION OF CERTAIN FACTORS THAT
SHOULD BE CONSIDERED BY PARTICIPANTS IN THE EXCHANGE OFFER.


THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
  EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
  SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
  UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS, ANY REPRESENTATION TO THE
  CONTRARY IS A CRIMINAL OFFENSE.



                   The date of this Prospectus is      , 1998


     The Exchange Offer is being made to satisfy certain obligations of the
Company under the Registration Rights Agreement, dated as of February 4, 1998,
among the Company and the Initial Purchasers (the "Registration Rights
Agreement"). Upon consummation of the Exchange Offer, holders of Old Notes that
were not prohibited from participating in the Exchange Offer and did not tender
their Old Notes will not have any registration rights under the Registration
Rights Agreement with respect to such nontendered Old Notes and, accordingly,
such Old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon.


     Based on interpretations by the staff of the Commission with respect to
similar transactions, including no-action letters, the Company believes that
the New Notes issued pursuant to the Exchange Offer in exchange for Old Notes
may be offered for resale, resold and otherwise transferred by any holder of
such New Notes (other than any such holder which is an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act of 1933, as
amended (the "Securities Act")) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holder's business, such
holder has no arrangement or understanding with any person to participate in
the distribution of such New Notes and neither the holder nor any other person
is engaging in or intends to engage in a distribution of the New Notes. Each
broker-dealer that receives New Notes for its own account in exchange for Old
Notes must acknowledge that it will deliver a prospectus in connection with any
resale of its New Notes. A broker-dealer who acquired Old Notes directly from
the Company can not exchange such Old Notes in the Exchange Offer. The Letter
of Transmittal states that by so acknowledging and by delivering a prospectus,
a broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of the New Notes received in exchange for the Old Notes acquired
by the broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that they will make this Prospectus
available to any broker-dealer for use in connection with any such resale for a
period of 180 days after the Exchange Date (as defined) or, if earlier, until
all participating broker-dealers have so resold. See "Plan of Distribution."


     The New Notes will evidence the same debt as the Old Notes and will be
entitled to the benefits of the Indenture (as defined). For a more complete
description of the terms of the new Notes, see "Description of Notes." There
will be no cash proceeds to the Company from the Exchange Offer. The New Notes
will be subordinated in right of payment to all current and future Senior Debt
(as defined) of the Company. The New Notes will also be effectively
subordinated to all indebtedness and other liabilities and commitments
(including trade payables and lease obligations) of the Company's subsidiaries.
As of September 30, 1997, after giving pro forma effect to the Offering and the
application of the net proceeds therefrom, the New Notes would have been
subordinated to approximately $72.2 million of Senior Debt of the Company and
indebtedness and other obligations of the Company's subsidiaries. In addition,
the Company would have had $121.5 million of borrowings available under the
Credit Facility (as defined). The Indenture will permit the Company and its
subsidiaries to incur additional indebtedness, including additional Senior
Debt, in the future.


     The Old Notes were originally issued and sold on February 4, 1998 in an
offering of $200.0 million aggregate principal amount (the "Offering," as
defined). The Offering was exempt from registration under the Securities Act in
reliance upon the exemptions provided by Rule 144A and Section 4(2) of the
Securities Act. Accordingly, the Old Notes may not be reoffered, resold or
otherwise pledged, hypothecated or transferred in the United States unless so
registered or unless an exemption from the registration requirements of the
Securities Act and applicable state securities laws is available.


     The Company has not entered into any arrangement or understanding with any
person to distribute the New Notes to be received in the Exchange Offer, and to
the best of the Company's information and belief, each person participating in
the Exchange Offer is acquiring the New Notes in its ordinary


                                       i


course of business and has no arrangement or understanding with any person to
participate in the distribution of the New Notes to be received in the Exchange
Offer. Any person participating in the Exchange Offer who does not acquire the
Exchange Notes in the ordinary course of business: (i) cannot rely on the above
referenced no-action letters; (ii) cannot tender its Old Notes in the Exchange
Offer; and (iii) must comply with the registration and prospectus delivery
requirements of the Securities Act.


     The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Old Notes being tendered for exchange. However, the Exchange Offer is
subject to certain customary conditions which may be waived by the Company. The
Exchange Offer will expire at 5:00 p.m., New York City time, on      , 1998,
unless extended (as it may be so extended, the "Expiration Date"), provided
that the Exchange Offer shall not be extended beyond 30 business days from the
date of this Prospectus. The date of acceptance for exchange of the Old Note
for the New Notes (the "Exchange Date") will be the first business day
following the Expiration Date or as soon as practicable thereafter. Old Notes
tendered pursuant to the Exchange Offer may be withdrawn at any time prior to
the Expiration Date; otherwise such tenders are irrevocable.


     There has not previously been any public market for the Notes. If a market
for the New Notes should develop, the New Notes could trade at a discount from
their initial offering price. The Company does not intend to apply for listing
of the New Notes on any securities exchange or in any automated quotation
system. There can be no assurance that an active trading market for the New
Notes will develop.

                                    SUMMARY


     THE FOLLOWING INFORMATION IS QUALIFIED IN ITS ENTIRETY BY THE MORE
DETAILED INFORMATION AND FINANCIAL STATEMENTS AND NOTES THERETO APPEARING
ELSEWHERE OR INCORPORATED BY REFERENCE HEREIN. UNLESS OTHERWISE SPECIFIED, ALL
REFERENCES TO "MASTEC" OR THE "COMPANY" INCLUDE MASTEC, INC., ITS CONSOLIDATED
SUBSIDIARIES AND ITS 50%-OWNED AFFILIATES IN ARGENTINA, CHILE AND PERU.



                                  THE COMPANY


     MasTec is one of the world's largest contractors specializing in the
design, installation and maintenance of infrastructure for the rapidly growing
telecommunications industry. The Company focuses on the installation of aerial
and underground copper, coaxial and fiber optic cable networks as well as
wireless antenna networks ("outside plant services"). The Company believes it
is the largest independent contractor for these systems in the United States
and Spain, and one of the largest in Argentina, Brazil, Chile and Peru. The
Company also installs central office switching equipment, and designs, installs
and maintains integrated voice, data and video local and wide area networks
inside buildings ("inside wiring"). Clients for the Company's services include
major domestic and international telecommunications service providers such as
the regional bell operating companies ("RBOCs"), other local exchange carriers,
competitive access providers, cable television operators, long-distance
operators and wireless phone companies. MasTec believes it is well positioned
to benefit from the significant growth taking place in the global
telecommunications market.


     MasTec has experienced significant and consistent growth as a result of
its ability to identify and integrate strategic acquisitions, its competitive
position as one of the largest providers of infrastructure services and
favorable trends in the telecommunications industry. The Company's revenue has
increased from $142.6 million in 1994 to $534.1 million in 1996 and from $355.8
million for the first nine months of 1996 to $500.1 million for the same period
in 1997. EBITDA (as defined) has also increased from $18.2 million in 1994 to
$71.2 million in 1996 and from $46.1 million in the first nine months of 1996
to $74.0 million in the same period in 1997. The Company expects to continue to
grow through additional strategic acquisitions as well as through internal
expansion. Since January 1996, the Company has completed 13 domestic and two
foreign acquisitions and actively continues to pursue complimentary
acquisitions in the highly fragmented telecommunications infrastructure
industry. Internal growth is expected to be driven by the expansion of the
global telecommunications industry resulting from (i) continued global
deregulation, which is allowing numerous new service providers to enter the
marketplace and is increasing the competitive pressure on existing participants
to upgrade and expand their networks; (ii) increasing consumer demand for
advanced communications services which require the upgrading of existing
infrastructure to handle increased bandwidth needs; and (iii) increasing
reliance on outsourcing of infrastructure needs to full service contractors by
service providers in an effort to reduce costs and focus on their core
competencies.


COMPETITIVE STRENGTHS


     The Company seeks to differentiate itself from its competitors through the
following characteristics:


     STRONG CUSTOMER RELATIONSHIPS. Founded in 1929, the Company has developed
strong relationships with numerous telecommunications service providers by
providing high quality services in a cost and time efficient manner. The
Company has been providing services to Telefonica de Espana, S.A.
("Telefonica") and BellSouth Telecommunications, Inc. ("BellSouth"), its two
largest customers, since 1950 and 1969, respectively, and maintains similar
long-term relationships with many of its other customers. MasTec currently has
23 multi-year service contracts with Telefonica, the RBOCs and other


                                       1


telecommunications service providers for certain of their outside plant
requirements up to a specific dollar amount per job and within certain
geographic areas.


     DIVERSE CUSTOMER BASE. MasTec provides a full range of infrastructure
services to a diverse customer base. Domestically, the Company provides outside
plant services to local exchange customers such as BellSouth, US West
Communications, Inc., SBC Communications, Inc., United Telephone Company of
Florida, Inc. (a subsidiary of Sprint Corporation ("Sprint")) and GTE
Corporation. The Company also provides outside plant services to competitive
local exchange carriers such as MFS Communications Company, Inc., Sprint
Metropolitan Networks, Inc. and MCI Metro, Inc. (the local telephone
subsidiaries of Sprint and MCI Communications Corporation ("MCI"),
respectively), cable television operators such as Time Warner Inc., Cox
Communications, Inc. and Marcus Cable Company, long distance carriers such as
MCI and Sprint, and wireless communications providers such as PrimeCo Personal
Communications LP and Sprint Spectrum, L.P. Internationally, the Company
provides outside plant services, turn-key switching systems installation and
inside wiring services primarily to Telefonica, the principal telephone company
in Spain, and Telefonica's affiliates in Argentina, Chile and Peru. In July
1997, the Company also began servicing the local telephone subsidiaries of
Telecomunicacoes Brasileiras S.A., the Brazilian government-owned
telecommunications system ("Telebras"), in Sao Paulo, Rio de Janeiro, Parana
and other states in the more populous and developed Southern region of Brazil,
as well as Companhia Riograndense de Telecommunicacoes, S.A. ("CRT"), the local
telephone company in Rio Grande do Sul which is partly owned by Telefonica.


     The Company renders inside wiring services nationwide to large corporate
customers with multiple locations such as First Union National Bank,
International Business Machines Corporation ("IBM") and Dean Witter Reynolds
Inc., and to universities and health care providers.


     TURN-KEY CAPABILITIES. The Company believes it is one of the few
contractors capable of providing all of the design, installation and
maintenance services necessary for a cable or wireless network starting from a
transmission point, such as a central office or headend, and running
continuously through aerial and underground cables to the ultimate end users'
voice and data ports, cable outlets or cellular stations. The Company can also
install the switching devices at a central office or set up local and wide area
voice, data and video networks to expand a business's telecommunications
infrastructure both inside a specific structure or between multiple structures.
 


     The Company believes that its customers increasingly are seeking
comprehensive solutions to their infrastructure needs by turning to fewer
qualified contractors who have the size, financial capability and technical
expertise to provide a full range of infrastructure services. The Company
believes that this trend will accelerate as industry consolidations increase
and as these consolidated entities begin to provide bundled services to end
users. The Company believes it has positioned itself, through acquisitions and
internal growth, as a full service provider of outside plant and inside wiring
infrastructure services to take advantage of this trend.


     BROAD GEOGRAPHIC PRESENCE. The Company has significantly broadened its
geographic presence in recent years through strategic acquisitions.
Domestically, MasTec has expanded beyond its historical base in the
Southeastern United States and currently has operations in over 30 states in
the Southeast, Southwest, West and upper Midwest regions of the country. The
Company also substantially increased its international operations through the
acquisition, in April 1996, of Sistemas e Instalaciones de Telecomunicacion,
S.A. ("Sintel"), the largest telecommunications infrastructure contractor in
Spain, and through the acquisition, in July 1997, of a majority interest in
MasTec Inepar S.A. Sistemas de Telecomunicacoes ("MasTec Inepar"), a leading
telecommunications construction company in Brazil. Due to its broad geographic
presence, the Company believes that it is well suited to service customers with
operations across the United States as well as companies who are active in
multiple areas of the world such as multinational corporations and
telecommunications service providers that are expanding into international
markets. In addition, by developing business in many geographic regions, the
Company believes it is less susceptible to changes in the market dynamics in
any one region.

GROWTH STRATEGY


     The Company is pursuing a disciplined strategy of growth and
diversification in its core business through strategic acquisitions and
internal expansion as follows:


     STRATEGIC ACQUISITIONS. The Company plans to continue to pursue strategic
acquisitions in the fragmented telecommunications and utility infrastructure
industry that either expand its geographic coverage and customer base or
broaden the range of services it can offer to clients. The Company focuses its
acquisition efforts primarily on companies with successful track records and
strong management. The Company has acquired 15 companies since January 1996 and
has significant experience in identifying, purchasing and integrating
telecommunications infrastructure businesses both domestically and
internationally. Management believes that MasTec is able to improve the
acquired companies' operating performance by providing strategic guidance,
administrative support, greater access to capital and savings in purchasing and
insurance costs.


     INTERNAL EXPANSION. The Company believes it is poised to capitalize on the
anticipated growth in its industry due to its status as one of the world's
largest telecommunications infrastructure contractors and its strong customer
relationships. The International Telecommunications Union estimates that
between 1996 and 2000 telecommunications infrastructure investment will exceed
$50 billion in the United States and $600 billion worldwide. In addition, the
Company believes that the RBOCs and other utilities in the United States, which
still conduct a significant portion of their construction work in-house, will
out-source more infrastructure construction in the future in response to
competitive pressures to cut costs, streamline their operations and focus on
their core competencies. The Company believes that its reputation for quality
and reliability, operating efficiency, financial strength, technical expertise,
presence in key geographic areas and ability to offer a full range of
construction services make it well positioned to compete for this business,
particularly the larger, more technically complex infrastructure projects.


     The Company also anticipates that its Brazilian operations will become a
more significant part of its operations. MasTec Inepar, in its first two months
of operations ended September 30, 1997, generated revenue and EBITDA (net of
minority interest) of $35.0 million and $2.7 million, respectively, and at
September 30, 1997 had a backlog of approximately $245.0 million. The Brazilian
government has estimated that approximately $75 billion will need to be
invested over a seven year period in order to modernize and expand Brazil's
telecommunications infrastructure. To accomplish this objective, the government
has stated its intention of deregulating and privatizing Brazil's
telecommunications system. The Company believes that, through MasTec Inepar, it
is well positioned to participate in this anticipated expansion.


     In addition to focusing on its core telecommunications customers, the
Company plans to achieve incremental growth by continuing to develop
complementary lines of businesses. These businesses include the provision of
premise wiring services to corporations and infrastructure construction
services to the electric power industry and other public utilities.

                             THE INITIAL OFFERING


     Pursuant to a Purchase Agreement dated as of January 30, 1998 (the
"Purchase Agreement"), the Company sold Old Notes in an aggregate principal
amount of $200.0 million to the Initial Purchasers on February 4, 1998. The
Initial Purchasers subsequently resold the Old Notes purchased from the Company
to qualified institutional buyers pursuant to Rule 144A under the Securities
Act and to certain institutional accredited investors (as defined in Rule
501(A)(1), (2), (3) or (7) under the Securities Act). A portion of the net
proceeds from the Initial Offering, estimated to have been approximately $194.2
million after deducting discounts to the Initial Purchasers and estimated
Offering expenses, were used to repay approximately $82.4 million of
outstanding indebtedness under the Credit Facility (as defined), under which
borrowings bore interest at LIBOR (London Interbank Offered Rate) plus the
applicable LIBOR margin, currently 1.00%. The remaining net proceeds from the
Offering will be used by the Company for general corporate purposes, including
acquisitions, working capital needs and capital expenditures.



                              THE EXCHANGE OFFER


Securities Offered.........   Up to $200.0 million aggregate principal amount

                              identical in all material respects, except for
                              certain transfer restrictions, registration rights
                              and liquidated damages ("Liquidated Damages") for
                              Registration Defaults relating to the Old Notes
                              which will not apply to the New Notes. See
                              "Description of Notes."


The Exchange Offer.........   The Company is offering to exchange $1,000
                              principal amount of New Notes for each $1,000

                              Offer" for a description of the procedures for
                              tendering Old Notes. The Exchange Offer satisfies
                              the registration obligations of the Company under
                              the Registration Rights Agreement. Upon
                              consummation of the Exchange Offer, holders of Old
                              Notes that were not prohibited from participating

                              the Registration Rights Agreement with respect to
                              such nontendered Old Notes and, accordingly, such
                              Old Notes will continue to be subject to the
                              restrictions on transfer contained in the legend
                              thereon.

                              be so extended, the "Expiration Date"), provided
                              that the Exchange Offer shall not be extended
                              beyond 30 business days from the date of this
                              Prospectus. Tender of Old Notes pursuant to the

                              holder as


                                       4

                              "Exchange Date") will be the first business day
                              following the Expiration Date or as soon as
                              practicable thereafter.


Accrued Interest on the
 New Notes..................  Each New Note will bear interest from the most
                              recent date to which interest has been paid on the
                              Old Note or, if no such payment has been made,
                              from February 4, 1998.


Federal Income
 Tax Considerations.........  The Exchange Offer will not result in any income,
                              gain or loss to the holders of Notes or the
                              Company for federal income tax purposes. See
                              "Certain Federal Income Tax Considerations."


Use of Proceeds............   There will be no proceeds to the Company from
                              the exchange of New Notes for the Old Notes
                              pursuant to the Exchange Offer.


Exchange Agent.............   First Trust National Association, the Trustee
                              under the Indenture, is serving as exchange agent
                              (the "Exchange Agent") in connection with the
                              Exchange Offer.



                    CONSEQUENCES OF EXCHANGING OR FAILURE TO
               EXCHANGE OLD NOTES PURSUANT TO THE EXCHANGE OFFER


     Generally, holders of Old Notes (other than any holder who is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act) who exchange their Old Notes for New Notes pursuant to the Exchange Offer
may offer their New Notes for resale, resell their New Notes, and otherwise
transfer their New Notes without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided such New Notes
are acquired in the ordinary course of the holder's business, such holders have
no arrangement with any person to participate in a distribution of such New
Notes and neither the holder nor any other person is engaging in or intends to
engage in a distribution of the New Notes. A broker-dealer who acquired Old
Notes directly from the Company can not exchange such Old Notes in the Exchange
Offer. Each broker-dealer that receives New Notes for its own account in
exchange for Old Notes must acknowledge that it will deliver a prospectus in
connection with any resale of its New Notes. See "Plan of Distribution." To
comply with the securities laws of certain jurisdictions, it may be necessary
to qualify for sale or register the New Notes prior to offering or selling such
New Notes. The Company is required, under the Registration Rights Agreement, to
register the New Notes in any jurisdiction requested by the holders, subject to
certain limitations. Upon consummation of the Exchange Offer, holders that were
not prohibited from participating in the Exchange Offer and did not tender
their Old Notes will not have any registration rights under the Registration
Rights Agreement with respect to such nontendered Old Notes, and accordingly,
such old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon. See "The Exchange Offer--Consequences of
Failure to Exchange."

                       SUMMARY DESCRIPTION OF THE NOTES


Issuer.....................   MasTec, Inc.


Securities Offered.........   $200.0 million aggregate principal amount of
                              7-3/4% Series B Senior Subordinated Notes due 2008
                              (the "New Notes," and collectively with the Old
                              Notes, the "Notes"). The terms of the New Notes
                              and the Old Notes are substantially identical in
                              all material respects, except for certain transfer
                              restrictions, registration rights and Liquidated
                              Damages for Registration Defaults relating to the
                              Old Notes which will not apply to the New Notes.
                              See "Description of Notes."


Maturity Date..............   February 1, 2008.


Interest Rate and
 Payment Dates..............  The Notes bear interest at a rate of 7-3/4% per
                              annum, payable semi-annually in arrears on
                              February 1 and August 1 of each year, commencing
                              August 1, 1998.


Ranking....................   The Notes are subordinated in right of payment
                              to all existing and future Senior Debt of the
                              Company. In addition, the Notes are effectively
                              subordinated to all indebtedness and other
                              liabilities and commitments (including trade
                              payables and lease obligations) of the Company's
                              subsidiaries. As of September 30, 1997, after
                              giving pro forma effect to the Offering and the
                              application of the net proceeds therefrom, the
                              Notes would have been subordinated to
                              approximately $72.2 million of Senior Debt of the
                              Company and indebtedness and other obligations of
                              the Company's subsidiaries. In addition, the
                              Company would have had $121.5 million of
                              borrowings available under the Credit Facility.


Optional Redemption........   The Notes will be redeemable, at the option of
                              the Company, in whole or in part, at any time
                              after February 1, 2003, at the redemption prices
                              set forth herein, plus accrued and unpaid
                              interest, if any, to the redemption date. In
                              addition, on or prior to February 1, 2001, the
                              Company may redeem up to one-third of the
                              aggregate principal amount of the Notes at a
                              redemption price of 107.750% of the principal
                              amount thereof, plus accrued and unpaid interest,
                              if any, thereon to the redemption date with the
                              net cash proceeds of an offering of Equity
                              Interests (other than Disqualified Stock) of the
                              Company; PROVIDED, that at least $133.3 million in
                              principal amount of the Notes remain outstanding
                              immediately after the occurrence of such
                              redemption.


Change of Control..........   In the event of a Change of Control, the Company
                              will be required to make an offer to each holder
                              of Notes to repurchase such holder's Notes at a
                              repurchase price equal to 101% of the principal
                              amount thereof, plus accrued and unpaid interest,
                              if any, thereon to the repurchase date.


                                       6


Certain Covenants..........   The indenture pursuant to which the Notes were
                              or will be issued (the "Indenture") contains
                              certain covenants that, among other things, limit
                              the ability of the Company and its Restricted
                              Subsidiaries (as defined) to incur additional
                              Indebtedness (as defined) and issue preferred
                              stock, pay dividends or make other distributions,
                              repurchase Equity Interests or make other
                              Restricted Payments (as defined), create certain
                              Liens (as defined), enter into certain
                              transactions with Affiliates (as defined), sell
                              assets or enter into certain mergers and
                              consolidations.


Exchange Offer;
Registration Rights........   Pursuant to a Registration Rights Agreement (the
                              "Registration Rights Agreement") between the
                              Company and the Initial Purchasers, the Company
                              agreed (i) to file a registration statement,
                              within 60 days after the consummation of the
                              Offering (the "Exchange Offer Registration
                              Statement"), with respect to an offer to exchange
                              the Old Notes for a new issue of debt securities
                              of the Company (the "Exchange Notes") registered
                              under the Securities Act with terms substantially
                              identical to those of the Old Notes (the "Exchange
                              Offer") and (ii) to use its best efforts to cause
                              such registration statement to be declared
                              effective by the Commission within 120 days after
                              the consummation of the Offering. In addition,
                              under certain circumstances, the Company may be
                              required to file a shelf registration statement
                              (the "Shelf Registration Statement") to cover
                              resales of the Notes by the holders thereof. If
                              the Company fails to satisfy these registration
                              obligations, it will be required to pay liquidated
                              damages ("Liquidated Damages") to the holders of
                              Notes under certain circumstances. See
                              "Description of Notes--Registration Rights;
                              Liquidated Damages."

     Prospective participants in the Exchange Offer should take into account
the specific considerations set forth under "Risk Factors" as well as the other

     The following summary financial information for each of the years in the
three year period ended December 31, 1996 has been derived from the Company's
consolidated financial statements, which have been audited by Coopers &
Lybrand, L.L.P., independent auditors, whose report thereon is included
elsewhere in this Prospectus. The summary financial information for the nine
month periods ended September 30, 1996 and September 30, 1997 has been derived
from the Company's unaudited condensed consolidated financial statements which,
in the opinion of management, contain all adjustments (consisting only of
normal and recurring adjustments) necessary for a fair presentation of the
Company's financial position and results of operations at such dates and for
such periods. The information presented below should be read in conjunction
with, and is qualified in its entirety by reference to, "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the Company's consolidated financial statements and the notes thereto appearing
elsewhere in this Prospectus.

    Note 2 of Notes to Consolidated Financial Statements.
(2) Includes the results of Burnup & Sims Inc. from March 11, 1994.
(3) Includes the results of Sintel from May 1, 1996.
(4) Income from continuing operations excludes a pro forma adjustment for
    income taxes related to companies which were S corporations and therefore
    not subject to corporate federal income taxes.
(5) EBITDA represents income from continuing operations plus provision for
    income taxes (less the tax effect attributable to minority interests),
    non-recurring or unusual charges, interest expense (net of interest
    income) and depreciation and amortization, less equity in earnings of
    unconsolidated companies (except to the extent of cash dividends
    received). EBITDA is used by management and certain investors as an
    indicator of a company's historical ability to service debt. Management
    believes that an increase in EBITDA is an indicator of the Company's
    improved ability to service existing debt, to sustain potential future
    increases in debt and to satisfy capital requirements. However, EBITDA is
    not intended to represent cash flows for the period, nor has it been
    presented as an alternative to either (i) operating income (as determined
    by generally accepted accounting principles) as an indicator of operating
    performance or (ii) cash flows from operating, investing and financing
    activities (as determined by generally accepted accounting principles) and
    is thus susceptible to varying calculations. EBITDA as presented may not
    be comparable to other similarly titled measures of other companies.
(6) Interest expense represents total interest expense (excluding amortization
    of deferred financing costs and original issue discount) less interest
    income. Pro forma net interest expense gives effect to the Offering and
    the application of the net proceeds therefrom, assuming such transactions
    occurred on January 1, 1996.

    proceeds therefrom as if they had occurred on September 30, 1997.

OBLIGATION TO REVISE THESE FORWARD-LOOKING STATEMENTS TO REFLECT FUTURE EVENTS
OR CIRCUMSTANCES. THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN
ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS BEFORE PARTICIPATING IN
THE EXCHANGE OFFER.



CONSEQUENCES OF FAILURE TO EXCHANGE


     Upon consummation of the Exchange Offer, holders of Old Notes that were
not prohibited from participating in the Exchange Offer and did not tender
their Old Notes will not have any registration rights under the Registration
Rights Agreement with respect to such nontendered Old Notes and, accordingly,
such Old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon. In general, the Old Notes may not be offered
or sold, unless registered under the Securities Act and applicable state
securities laws, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. The
Company does not intend to register the Old Notes under the Securities Act.
Based on interpretations by the staff of the Commission with respect to similar
transactions, the Company believes that the New Notes issued pursuant to the
Exchange Offer may be offered for resale, resold and otherwise transferred by
any holder of such New Notes (other than any such holder which is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act) without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such New Notes are acquired in
the ordinary course of such holder's business, such holder has no arrangement
or understanding with any person to participate in the distribution of such New
Notes and neither the holder nor any other person is engaging in or intends to
engage in a distribution of the New Notes. A broker-dealer who acquired Old
Notes directly from the Company can not exchange such Old Notes in the Exchange
Offer. Each broker-deal that receives New Notes for its own account in exchange
for Old Notes must acknowledge that it will deliver a prospectus in connection
with any resale of its New Notes. The Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. This Prospectus, as it may be amended or supplemented from time
to time, may be used by a broker-dealer in connection with resales of the New
Notes received in exchange for the Old Notes acquired by the broker-dealer as a
result of market-making activities or other trading activities. The Company has
agreed that it will make this Prospectus available to any broker-dealer for use
in connection with any such resale for a period of 180 days after the Exchange
Date or, if earlier, until all participating broker-dealers have so resold. See
"Plan of Distribution." The New Notes may not be offered or sold unless they
have been registered or qualified for sale under applicable state securities
laws or an exemption from registration or qualification is available and is
complied with. The Company is required, under the Registration Rights
Agreement, to register the New Notes in any jurisdiction requested by the
holders, subject to certain limitations.

LEVERAGE


     At September 30, 1997, after giving pro forma effect to the Offering and
the application of the net proceeds as set forth herein under "Use of
Proceeds," the Company would have had approximately $271.9 million in total
indebtedness and approximately $121.5 million of available borrowings under the
Credit Facility. In addition, subject to certain restrictions set forth in the
Indenture, the Company may incur additional indebtedness, including Senior
Debt, in the future for acquisitions, capital expenditures and other corporate
purposes. The Company's level of indebtedness will have several important
effects on its future operations, including, without limitation, (i) a portion
of the Company's cash flow from operations must be dedicated to the payment of
interest and principal on its indebtedness, (ii) the Company's leveraged
position will increase its vulnerability to adverse changes in general economic
and industry conditions, as well as to competitive pressure, and (iii) the
Company's ability to obtain additional financing for working capital, capital
expenditures, acquisitions, general corporate and other purposes may be
limited. The Company's ability to meet its debt service obligations and to
reduce its total indebtedness will be dependent upon the Company's future
performance, which will be subject to general economic conditions, industry
cycles and financial, business and other factors affecting the operations of
the Company, many of which are beyond its control. There can be no assurance
that the Company's business will continue to generate cash flow at or above
current levels. If the Company is unable to generate sufficient cash flow from
operations in the future to service its debt, it may be required, among other
things, to seek additional financing in the debt or equity markets, to
refinance or restructure all or a portion of its indebtedness, including the
Notes, to sell selected assets or to reduce or delay planned capital
expenditures or acquisitions. There can be no assurance that any such measures
would be sufficient to enable the Company to service its debt or that any such
financing, refinancing or sale of assets would be available on economically
favorable terms.


RESTRICTIONS IMPOSED BY CREDIT FACILITY AND INDENTURE


     The Credit Facility and the Indenture contain a number of covenants that
restrict the ability of the Company to, among other things, dispose of assets,
merge or consolidate with another entity, incur additional indebtedness, create
liens, make capital expenditures, pay dividends or make other investments or
acquisitions. The Credit Facility also contains requirements that the Company
maintain certain financial ratios and restricts the ability of the Company to
prepay the Company's other indebtedness, including the Notes. The ability of
the Company to comply with such provisions may be affected by events that are
beyond the Company's control. The breach of any of these covenants could result
in a default under the Credit Facility and the Indenture and a subsequent
acceleration of such indebtedness. In the event of acceleration of such
indebtedness, payments to holders of the Notes could be limited by the
subordination provisions of the Indenture. See "Description of Notes--
Subordination." In addition, as a result of these covenants, the ability of the
Company to respond to changing business and economic conditions and to secure
additional financing, if needed, may be restricted significantly, and the
Company may be prevented from engaging in transactions that might otherwise be
considered beneficial to the Company. See "Description of Certain Indebtedness"
and "Description of Notes--Certain Covenants."


SUBORDINATION


     The payment of principal of and interest on, and any premium or other
amounts owing in respect of, the Notes are subordinated to the prior payment in
full of all existing and future Senior Debt of the Company, including all
amounts owing under the Credit Facility. The Notes are also effectively
subordinated to all Indebtedness and other liabilities and commitments
(including trade payables and lease obligations) of the Company's subsidiaries.
As of September 30, 1997, after giving pro forma effect to the Offering and the
application of the net proceeds therefrom, the Notes would have been
subordinated to approximately $72.2 million of Senior Debt of the Company and
indebtedness and other obligations of the Company's subsidiaries. In addition,
the Company would have had approximately $121.5 million of available borrowings
under the Credit Facility. Consequently, in the event of a bankruptcy,
liquidation, dissolution, reorganization or similar proceeding with respect to
the


                                       10


Company, assets of the Company will be available to pay obligations under the
Notes only after all of its Senior Debt has been paid in full, and there can be
no assurance that there will be sufficient assets to pay amounts due on all or
any of the Notes. In addition, under certain circumstances, the Company may be
prohibited by the Indenture from paying amounts due in respect of the Notes, or
from purchasing, redeeming or otherwise acquiring the Notes, if a default
exists with respect to Senior Debt. See "Description of Notes--Subordination."


HOLDING COMPANY STRUCTURE

     The Company is a holding company that conducts substantially all of its
operations through its subsidiaries and the Company's only significant asset is
the capital stock of its subsidiaries. The Notes will be obligations
exclusively of the Company and will not be guaranteed by any of the Company's
subsidiaries, except under certain limited circumstances. See "Description of
Notes--Certain Covenants--Limitations on Guarantees of Company Indebtedness by
Restricted Subsidiaries." As a result, the Company is dependent on dividends or
other intercompany transfers of funds from its subsidiaries to meet the
Company's debt service and other obligations, including its obligations under
the Notes, which may be restricted by applicable law. In addition, to the
extent that any such subsidiary incurs indebtedness and becomes insolvent or is
liquidated, creditors of such subsidiary would be entitled to payment from the
proceeds of such subsidiary's assets before the Company and its creditors would
derive any value from such subsidiary's assets.


DEPENDENCE ON KEY CUSTOMERS AND THE TELECOMMUNICATIONS INDUSTRY


     The Company derives a substantial portion of its revenue from customers in
the telecommunications industry, particularly Telefonica and its affiliates and
BellSouth. For the year ended December 31, 1996 and the nine months ended
September 30, 1997, approximately 31% and 27%, respectively, of the Company's
revenue was derived from services performed for Telefonica and its affiliates
and approximately 13% of the Company's revenue was derived from services
performed for BellSouth for both periods. The Company anticipates that it will
continue to derive a significant portion of its revenue from services performed
for Telefonica and its affiliates and BellSouth. The Company also anticipates
that it will derive significant revenue in the future from the local telephone
operating companies that form the Brazilian Telebras system. The loss of any of
these customers or a significant reduction in the amount of business generated
by these customers could have a material adverse effect on the Company's
results of operations.

     In addition, there are a number of factors that could adversely affect
these and the Company's other customers and their ability or willingness to
fund capital expenditures in the future, which in turn could have a material
adverse effect on the Company's results of operations. These factors include
the potential adverse nature of, or the uncertainty caused by, changes in
governmental regulation, technological changes, increased competition, adverse
financing conditions for the industry and economic conditions generally.
Further, the volume of work awarded under contracts with the Company's public
utility customers is subject to periodic appropriations during the term of the
contract, and a failure by the customer to receive sufficient appropriations
could result in a reduction in the volume of work under these contracts or a
delay in payments, which in turn could negatively affect the Company.


CANCELLATION CLAUSES IN CONTRACTS; FAILURE TO WIN PUBLIC BIDS

     Many of the Company's contracts with its customers, including most of its
master contracts and contracts with its public utility customers, are subject
to cancellation by the customer without notice or on relatively short notice,
typically 90 to 180 days, even if the Company is not in default under the
contract. There can be no assurance that the Company's customers will not
terminate the Company's contracts pursuant to these termination clauses even if
the Company is in compliance with the contract. Many of the Company's
contracts, including master contracts, also are opened to public bid at the
expiration of the contract term, and there can be no assurance that the Company
will be the successful bidder on existing contracts that come up for bid.
Cancellation of a significant number of contracts by


                                       11


the Company's customers or the failure of the Company to win a significant
number of existing contracts upon re-bid could have a material adverse effect
on the Company.


RISK INHERENT IN GROWTH STRATEGY


     The Company has grown rapidly through the acquisition of other companies
and its growth strategy is dependent in part on additional acquisitions. The
Company anticipates that it will make additional acquisitions and is actively
seeking and evaluating new acquisition candidates. There can be no assurance
that the Company will be able to continue to identify and acquire appropriate
businesses or obtain financing for acquisitions on satisfactory terms or that
acquired companies will perform as expected. The Company's growth strategy
presents the risks inherent in assessing the value, strengths and weaknesses of
growth opportunities, in evaluating the costs and uncertain returns of
expanding the operations of the Company and in integrating existing operations
with new acquisitions. Future competition for acquisition candidates could
raise prices for these targets and lengthen the time period required to recoup
the Company's investment. The Company's growth strategy also assumes there will
be a significant increase in demand for telecommunications and other
infrastructure services, which may not materialize. The Company's anticipated
growth may place significant demands on the Company's management and its
operational, financial and marketing resources. The Company's operating results
could be adversely affected if it is unable to integrate and manage acquired
companies successfully. Future acquisitions by the Company could also result in
the incurrence of additional debt and contingent liabilities, and amortization
expenses related to goodwill and other intangible assets, which could
materially adversely affect the Company's financial condition and results of
operations.


RISK OF FOREIGN OPERATIONS


     During 1996 and the first nine months of 1997, approximately 37% of the
Company's revenue was derived from international operations. Some of the
countries in which the Company conducts business have, in the past, experienced
political, economic or social instability, including expropriations, currency
devaluations, hyper-inflation, confiscatory taxation or other adverse
regulatory or legislative developments, or have limited the repatriation of
investment income, capital and other assets. There can be no assurance that
some of these circumstances will not occur in the future or that, if they
occur, they will not have a material adverse effect on the Company's financial
condition and results of operations.


     The Company conducts business in several foreign currencies that are
subject to fluctuations in the exchange rate relative to the U.S. dollar. The
Company's results of operations from foreign activities are translated into
U.S. dollars at the average prevailing rates of exchange during the period
reported, which average rates may differ from the actual rates of exchange in
effect at the time of actual conversion into U.S. dollars. The Company monitors
its currency exchange risk but currently does not hedge against this risk. At
September 30, 1997, the Company had recorded a $1.6 million cumulative negative
currency translation adjustment on its balance sheet to account for currency
fluctuations in the foreign countries in which it does business. There can be
no assurance that currency exchange fluctuations will not adversely affect the
Company's financial condition or results of operations. Additionally, although
the Company currently has no plans to repatriate significant earnings from its
international operations, there is no assurance that the Company could
repatriate such earnings without incurring significant tax liabilities.


SINTEL LABOR RELATIONS


     Substantially all of Sintel's work force in Spain is unionized. On
September 3, 1997, Sintel filed a petition with the Spanish labor authorities
to approve a restructuring of Sintel's work force. Following the filing of this
labor petition, Sintel's labor unions commenced half-day work stoppages which
continued through the first week of October 1997. Sintel has entered into an
agreement with its unions to resolve the current labor dispute, subject to
ratification and final documentation. There can be no assurance that workers
will ratify the agreement or that final documentation can be completed.


                                       12


Additionally, any future work stoppages or the failure to negotiate future
labor agreements on competitive terms could have a material adverse effect on
Sintel and on the Company's results of operations.


DEPENDENCE ON LABOR FORCE


     The Company's business is labor intensive with high employee turnover in
many operations. The low unemployment rate in the United States has made it
more difficult to find qualified personnel at low cost in some areas where the
Company operates. Shortages of labor or increased labor costs could have a
material adverse effect on the Company's operations. There can be no assurance
that the Company will be able to continue to hire and retain a sufficient labor
force of qualified persons.


DEPENDENCE ON SENIOR MANAGEMENT


     The Company's businesses are managed by a small number of key executive
officers, including Jorge Mas, the Company's Chairman, President and Chief
Executive Officer. The loss of services of certain of these executives could
have a material adverse effect on the Company. The Company's growth strategy
also is dependent on its ability to hire and retain additional qualified
management personnel. There can be no assurance that the Company will be able
to hire and retain such personnel.


COMPETITION


     The industry in which the Company competes is highly competitive and
fragmented. The Company competes with a number of contractors in the markets in
which it operates, ranging from small independent firms servicing local markets
to larger firms servicing regional markets, as well as with large national and
international equipment vendors on turn-key projects who subcontract
construction work to contractors other than the Company. These equipment
vendors typically are better capitalized and have greater resources than the
Company. There are relatively few barriers to entry into these markets and, as
a result, any business that has access to persons who possess technical
expertise and adequate financing may become a competitor of the Company.
Because of the highly competitive bidding environment in the United States for
the services provided by the Company, the price of a contractor's bid is often
the deciding factor in determining whether such contractor is awarded a
contract for a particular project. Internationally, the Company expects that
there will be increasing price competition as a result of privatization and
deregulation of previously monopolistic markets. There can be no assurance that
the Company's competitors will not develop the expertise, experience and
resources to provide services that achieve greater market acceptance or that
are superior in both price and quality to the Company's services, or that the
Company will be able to maintain and enhance its competitive position. In
addition, many turn-key infrastructure projects require vendor-financing, and
there can be no assurance that the Company will be able to provide such
financing on satisfactory terms or at all.


     The Company also faces competition from the in-house service organizations
of RBOCs and other customers and potential customers, which employ personnel
who perform some of the same types of services as those provided by the
Company. The Company's growth strategy is dependent in part on increased
outsourcing by these customers of their infrastructure construction work. There
can be no assurance that existing or prospective customers of the Company will
continue to outsource telecommunication or other infrastructure services or
increase their outsourcing of these services in the future.


POSSIBLE INABILITY TO FUND A CHANGE OF CONTROL OFFER


     Upon a Change of Control, the Company will be required to offer to
repurchase all outstanding Notes at 101% of the principal amount thereof, plus
accrued and unpaid interest and Liquidated Damages, if any, to the date of
repurchase. However, there can be no assurance that sufficient funds will be
available at the time of any Change of Control to make any required repurchases
of Notes tendered or that restrictions in the Credit Facility or other
indebtedness of the Company will allow the Company to make such required
repurchases. Notwithstanding these provisions, the Company could enter into


                                       13


transactions, including certain recapitalizations, that would not constitute a
Change of Control but would increase the amount of debt outstanding at such
time. See "Description of Notes--Repurchase at the Option of Holders."


CONTROLLING STOCKHOLDERS


     Jorge Mas, the Company's Chairman, President and Chief Executive Officer,
together with other family members beneficially own more than 50% of the
outstanding shares of Common Stock of the Company. Accordingly, they have the
power to control the affairs of the Company.


ABSENCE OF A PUBLIC MARKET FOR THE NOTES


     The New Notes will constitute a new issue of securities with no
established trading market. The Company does not intend to apply for listing of
the New Notes on any securities exchange. The Initial Purchasers have informed
the Company that they currently intend to make a market in the New Notes.
However, they are not obligated to do so, and any such market making may be
discontinued at any time without notice. In addition, any such market-making
activity will be subject to the limits imposed by the Securities Act and the
Exchange Act and may be limited during the Exchange Offer or the pendency of
the Shelf Registration Statement. Accordingly, no assurance can be given that
an active public or other market will develop for the New Notes or as to the
liquidity of or the trading market for the New Notes. If a trading market does
not develop or is not maintained, holders of the New Notes may experience
difficulty in reselling the New Notes or may be unable to sell them at all. If
a market for the New Notes develops, any such market may be discontinued at any
time.


     If a public trading market develops for the New Notes, future trading
prices of such securities will depend on many factors including, among other
things, prevailing interest rates, the Company's results of operations and the
market for similar securities. Depending on prevailing interest rates, the
market for similar securities and other factors, including the financial
condition of the Company, the New Notes may trade at a discount from their
principal amount.


FRAUDULENT CONVEYANCE STATUTES


     Under applicable provisions of federal bankruptcy law or comparable
provisions of state fraudulent transfer law, if, among other things, the
Company, at the time it incurred the indebtedness evidenced by the Notes (i)
(a) was or is insolvent or rendered insolvent by reason of such occurrence or
(b) was or is engaged in a business or transaction for which the assets
remaining with the Company constituted unreasonably small capital or (c)
intended or intends to incur, or believed or believes that it would incur,
debts beyond its ability to pay such debts as they mature, and (ii) the Company
received or receives less than reasonably equivalent value or fair
consideration for the incurrence of such indebtedness, then the Notes could be
voided, or claims in respect of the Notes could be subordinated to all other
debts of the Company. In addition, the payment of interest and principal by the
Company pursuant to the Notes could be voided and required to be returned to
the person making such payment, or to a fund for the benefit of the creditors
of the Company.


     The measures of insolvency for purposes of the foregoing considerations
will vary depending upon the law applied in any proceeding with respect to the
foregoing. Generally, however, the Company would be considered insolvent if (i)
the sum of its debts, including contingent liabilities, were greater than the
saleable value of all of its assets at a fair valuation or if the present fair
saleable value of its assets were less than the amount that would be required
to pay its probable liability on its existing debts, including contingent
liabilities, as they become absolute and mature or (ii) it could not pay its
debts as they become due. On the basis of historical financial information,
recent operating history and other factors, the Company believes that, after
giving effect to the indebtedness incurred in connection with the Offering, it
will not be insolvent, will not have unreasonably small capital for the
business in which it is engaged and will not incur debts beyond its ability to
pay such debts as they mature. There can be no assurance, however, as to what
standard a court would apply in making such determinations or that a court
would agree with the Company's conclusions in this regard.

                              THE EXCHANGE OFFER


PURPOSE AND EFFECT OF THE EXCHANGE OFFER


     On February 4, 1998, the Company issued $200.0 million aggregate principal
amount of Old Notes to Jefferies & Company, Inc., BancBoston Securities Inc.,
CIBC Oppenheimer Corp. and NationsBanc Montgomery Securities LLC (collectively,
the "Initial Purchasers"). The issuance was not registered under the Securities
Act in reliance upon the exemption under Rule 144A and Section 4(2) of the
Securities Act. In connection with the issuance and sale of the Old Notes, the
Company entered into a Registration Rights Agreement with the Initial
Purchasers dated as of February 4, 1998 (the "Registration Rights Agreement"),
which requires the Company to cause the Old Notes to be registered under the
Securities Act or to file with the Commission a registration statement under
the Securities Act with respect to an issue of new notes of the Company
identical in all material respects to the Old Notes, and use its best efforts
to cause such registration statement to become effective under the Securities
Act and, upon the effectiveness of that registration statement, to offer to the
holders of the Old Notes the opportunity to exchange their Old Notes for a like
principal amount of New Notes, which will be issued without a restrictive
legend and may be reoffered and resold by the holder without restrictions or
limitations under the Securities Act. A copy of the Registration Rights
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part. The Exchange Offer is being made pursuant to the
Registration Rights Agreement to satisfy the Company's obligations thereunder.


     Based on no-action letters issued by the staff of the Commission to third
parties, the Company believes that the New Notes issued pursuant to the
Exchange Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by any holder of such New Notes (other than any such
holder which is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holder's business, such
holder has no arrangement or understanding with any person to participate in
the distribution of such New Notes and neither the holder nor any other person
is engaging in or intends to engage in a distribution of the New Notes. A
broker-dealer who acquired Old Notes directly from the Company can not exchange
such Old Notes in the Exchange Offer. Any holder who tenders in the Exchange
Offer for the purpose of participating in a distribution of the New Notes
cannot rely on such interpretations by the staff of the Commission and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. Each broker-dealer
that receives New Notes for its own account in exchange for Old Notes, where
such Old Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such New Notes. See "Plan of
Distribution."


TERMS OF THE EXCHANGE OFFER


     Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal (which together constitute the
Exchange Offer), the Company will accept any and all Old Notes validly tendered
and not withdrawn prior to 5:00 p.m., New York City time, on the Expiration
Date (as defined herein). The Company will issue a principal amount of New
Notes in exchange for an equal principal amount of outstanding Old Notes
tendered and accepted in the Exchange Offer. Holders may tender some or all of
their Old Notes pursuant to the Exchange Offer. The date of acceptance for
exchange of the Old Notes for the New Notes (the "Exchange Date") will be the
first business day following the Expiration Date or as soon as practicable
thereafter.


     The terms of the New Notes and the Old Notes are substantially identical
in all material respects, except for certain transfer restrictions,
registration rights and Liquidated Damages for Registration Defaults relating
to the Old Notes which will not apply to the New Notes. See "Description of
Notes." The New Notes will evidence the same debt as the Old Notes. The New
Notes will be issued under and entitled to the benefits of the Indenture
pursuant to which the Old Notes were issued.


                                       15


     As of the date of this Prospectus, $200.0 million aggregate principal
amount of the Old Notes are outstanding. This Prospectus, together with the
Letter of Transmittal, is being sent to all registered holders of Old Notes.
Holders of Old Notes do not have any appraisal or dissenters' rights under
state law or the Indenture in connection with the Exchange Offer. The Company
intends to conduct the Exchange Offer in accordance with the provisions of the
Registration Rights Agreement and the applicable requirements of the Exchange
Act, and the rules and regulations of the Commission thereunder. Old Notes
which are not tendered and were not prohibited from being tendered for exchange
in the Exchange Offer will remain outstanding and continue to accrue interest
and to be subject to transfer restrictions, but will not be entitled to any
rights or benefits under the Registration Rights Agreement.


     Upon satisfaction or waiver of all the conditions to the Exchange Offer,
on the Exchange Date the Company will accept all Old Notes properly tendered
and not withdrawn and will issue New Notes in exchange therefor. For purposes
of the Exchange Offer, the Company shall be deemed to have accepted properly
tendered Old Notes for exchange when, as and if the Company had given oral or
written notice thereof to the Exchange Agent. The Exchange Agent will act as
agent for the tendering holders for the purposes of receiving the New Notes
from the Company.


     In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of such Old Notes, a properly completed and duly executed
Letter of Transmittal and all other required documents; provided, however, that
the Company reserves the absolute right to waive any defects or irregularities
in the tender or conditions of the Exchange Offer. If any tendered Old Notes
are not accepted for any reason set forth in the terms and conditions of the
Exchange Offer or if Old Notes are submitted for a greater principal amount
than the holder desires to exchange, such unaccepted or nonexchanged Old Notes
or substitute Old Notes evidencing the unaccepted portion, as appropriate, will
be returned without expense to the tendering holder thereof as promptly as
practicable after the expiration or termination of the Exchange Offer.


     Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer. See "Fees and Expenses."


EXPIRATION DATE; EXTENSION; AMENDMENTS

     The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
     , 1998, unless the Company, in its sole discretion, extends the Exchange
Offer, in which case the term "Expiration Date" shall mean the latest date and
time to which the Exchange Offer is extended; provided that the Exchange Offer
shall not be extended beyond 30 business days after the date of this
Prospectus.


     In order to extend the Expiration Date, the Company will notify the
Exchange Agent of any extension by oral or written notice and will mail to the
registered holders an announcement thereof, prior to 9:00 a.m., New York City
time, on the next business day after the then Expiration Date.


     The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "Conditions"
shall not have been satisfied, by giving oral or written notice of such delay,
extension or termination to the Exchange Agent or (ii) to amend the terms of
the Exchange Offer. Any such delay in acceptance, extension, termination or
amendment will be followed as promptly as practicable by oral or written notice
thereof. If the Exchange Offer is amended in a manner determined by the Company
to constitute a material change, the Company will promptly disclose such
amendment in a manner reasonably calculated to inform the holder of Old Notes
of such amendment.


     Without limiting the manner in which the Company may choose to make a
public announcement of any delay, extension, amendment or termination of the
Exchange Offer, the Company shall have no


                                       16


obligation to publish, advertise, or otherwise communicate any such public
announcement, other than by making a timely release to an appropriate news
agency.


INTEREST ON THE NEW NOTES

     New Notes will bear interest at the rate of 7-3/4% per annum, payable
semi-annually, in cash, on February 1 and August 1 of each year, from the most
recent date to which interest has been paid on the Old Notes or, if no such
payment has been made, from February 4, 1998.


CONDITIONS

     Notwithstanding any other term of the Exchange Offer, the Company will not
be required to exchange any new Notes for any Old Notes, and may terminate or
amend the Exchange Offer before the acceptance of any Old Notes for exchange,
if:


     (a) any action or proceeding is instituted or threatened in any court or
by or before any governmental agency with respect to the Exchange Offer which
seeks to restrain or prohibit the Exchange Offer or, in the Company's judgment,
would materially impair the ability of the Company to proceed the Exchange
Offer; or

     (b) any law, statute, rule or regulation is proposed, adopted or enacted,
or any existing law, statute, rule, order or regulation is interpreted, by any
government or governmental authority which, in the Company's judgment, would
materially impair the ability of the Company to proceed with the Exchange
Offer; or

     (c) the Exchange Offer or the consummation thereof would otherwise violate
or be prohibited by applicable law.

     If the Company determines in its sole discretion that any of these
conditions is not satisfied, the Company may (i) refuse to accept any Old Notes
and return all tendered Old Notes to the tendering holders, (ii) extend the
Exchange Offer and retain all Old Notes tendered prior to the expiration of the
Exchange Offer, subject, however, to the rights of holders who tendered such
Old Notes to withdraw their tendered Old Notes, or (iii) waive such unsatisfied
conditions with respect to the Exchange Offer and accept all properly tendered
Old Notes which have not been withdrawn. If such waiver constitutes a material
change to the Exchange Offer, the Company will promptly disclose such waiver by
means of a prospectus supplement that will be distributed to the registered
holders, and the Company will extend the Exchange Offer for a period of five to
ten business days, depending upon the significance of the waiver and the manner
of disclosure to the registered holders, if the Exchange Offer would otherwise
expire during such five to ten business day period.

     The foregoing conditions are for the sole benefit of the Company and may
be asserted by the Company regardless of the circumstances giving rise to any
such condition or may be waived by the Company in whole or in part at any time
and from time to time in their sole discretion. The failure by the Company at
any time to exercise any of the foregoing rights shall not be deemed a waiver
of any such right, and each such right shall be deemed an ongoing right which
may be asserted at any time and from time to time. Any determination by the
Company concerning the events described above shall be final and binding on all
parties.


PROCEDURES FOR TENDERING

     The tender of Old Notes by a holder as set forth below (including the
tender of Old Notes by book-entry delivery pursuant to the procedures of the
Depository Trust Company ("DTC")) and the acceptance thereof by the Company
will constitute an agreement between such holder and the Company in accordance
with the terms and subject to the conditions set forth in this Prospectus and
in the Letter of Transmittal.

     Only a holder of Old Notes may tender such Old Notes in the Exchange
Offer. To tender in the Exchange Offer, a holder must (i) complete, sign and
date the Letter of Transmittal, or a facsimile


                                       17


thereof, have the signatures thereon guaranteed if required by the Letter of
Transmittal, and mail or otherwise deliver such Letter of Transmittal or such
facsimile, together with the Old Notes (unless such tender is being effected
pursuant to the procedure for book-entry transfer described below) and any
other required documents, to the Exchange Agent prior to 5:00 p.m., New York
City time, on the Expiration Date, or (ii) comply with the guaranteed delivery
procedures described below. Delivery of all documents must be made to the
Exchange Agent at its address set forth herein.

     THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR
NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.

     Any beneficial owner whose Old Notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf. If such
beneficial owner wishes to tender on such owners' own behalf, such owner must,
prior to completing and executing the Letter of Transmittal and delivering of
such owner's Old Notes, either make appropriate arrangements to register
ownership of the Old Notes in such owner's name or obtain a properly completed
bond power from the registered holder. The transfer of registered ownership may
take considerable time.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by any Eligible Institution (as defined) unless
the Old Notes tendered pursuant thereto are tendered (i) by a registered holder
who has not completed the box entitled "Special Payment Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter of
Transmittal or a notice of withdrawal, as the case may be, are required to be
guaranteed, such guarantee must be by a member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution").

     If the Letter of Transmittal is signed by a person other than the
registered holder of any Old Notes listed therein, such Old Notes must be
endorsed or accompanied by a properly completed bond power, signed by such
registered holder as such registered holder's name appears on such Old Notes,
with the signature thereon guaranteed by an Eligible Institution. If the Letter
of Transmittal or any Old Notes or bond powers are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by the Company,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter of Transmittal.

     Any financial institution that is a participant in the book-entry transfer
facility for the Old Notes, DTC, may make book-entry delivery of Old Notes by
causing DTC to transfer such Old Notes into the Exchange Agent's account with
respect to the Old Notes in accordance with DTC's procedures for such transfer,
including if applicable the procedures under the Automated Tender Offer Program
("ATOP"). Although delivery of Old Notes may be effected through book-entry
transfer into the Exchange Agent's account at DTC, an appropriate Letter of
Transmittal with any required signature guarantee and all other required
documents must in each case be, or be deemed to be, transmitted to and received
and confirmed by the Exchange Agent at its address set forth below on or prior
to the Expiration Date, or, if the guaranteed delivery procedures described
below are complied with, within the time period provided under such procedures.
 


                                       18


     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes and withdrawal of tendered Old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding. The Company reserves the absolute right to reject
any and all Old Notes not properly tendered or any Old Notes the Company's
acceptance of which would, in the opinion of counsel of the Company, be
unlawful. The Company also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Old Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Old Notes must be cured within such time as the
Company shall determine. Although the Company intends to notify holders of
defects or irregularities with respect to tenders of Old Notes, neither the
Company, the Exchange Agent nor any other person shall incur any liability for
failure to give such notification. Tenders of Old Notes will not be deemed to
have been made until such defects or irregularities have been cured or waived.
Any Old Notes received by the Exchange Agent that are not properly tendered and
as to which the defects or irregularities have not been cured or waived will be
returned by the Exchange Agent to the tendering holders, unless otherwise
provided in the Letter of Transmittal, as soon as practicable following the
Expiration Date.


     In addition, the Company reserves the right in its sole discretion to
purchase or make offers for any Old Notes that remain outstanding subsequent to
the Expiration Date or, as set forth below under "Conditions," to terminate the
Exchange Offer and, to the extent permitted by applicable law, purchase Old
Notes in the open market, in privately negotiated transactions or otherwise.
The terms of any such purchases or offers could differ from the terms of the
Exchange Offer.


     By tendering, each holder will also represent to the Company (i) that the
New Notes acquired pursuant to the Exchange Offer are being obtained in the
ordinary course of business of the person receiving such New Notes, whether or
not such person is the holder, (ii) that neither the holder nor any such person
has an arrangement or understanding with any person to participate in the
distribution of such New Notes and (iii) that neither the holder nor any such
other person is an "affiliate," as defined in Rule 405 under the Securities
Act, of the Company, or that if it is an "affiliate," it will comply with the
registration and prospective delivery requirements of the Securities Act to the
extent applicable.


GUARANTEED DELIVERY PROCEDURES


     Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent prior to the
Expiration Date, or (iii) who cannot complete the procedures for book-entry
transfer of Old Notes to the Exchange Agent's account with DTC prior to the
Expiration Date, may effect a tender if:


     (a) The tender is made through an Eligible Institution;


     (b) On or prior to the Expiration Date, the Exchange Agent receives from
such Eligible Institution a properly completed and duly executed Notice of
Guaranteed Delivery (by facsimile transmission, mail or hand delivery) setting
forth the name and address of the holder, the certificate number(s) of such Old
Notes (if possible) and the principal amount of Old Notes tendered, stating
that the tender is being made thereby and guaranteeing that, within five
business trading days after the Expiration Date, (i) the Letter of Transmittal
(or facsimile thereof) together with the certificate(s) representing the Old
Notes and any other documents required by the Letter of Transmittal will be
deposited by the Eligible Institution with the Exchange Agent, or (ii) that
book-entry transfer of such Old Notes into the Exchange Agent's account at DTC
will be effected and confirmation of such book-entry transfer will be delivered
to the Exchange Agent; and


     (c) Such properly completed and executed Letter of Transmittal (or
facsimile thereof), as well as the certificate(s) representing all tendered Old
Notes in proper form for transfer and all other documents required by the
Letter of Transmittal, or confirmation of book-entry transfer of the Old Notes
into the Exchange Agent's account at DTC, are received by the Exchange Agent
within five


                                       19


business trading days after the Expiration Date. Upon request to the Exchange
Agent, a Notice of Guaranteed Delivery will be sent to holders who wish to
tender their Old Notes according to the guaranteed delivery procedures set
forth above.


TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL


     The Letter of Transmittal contains, among other things, the following
terms and conditions, which are part of the Exchange Offer:


     The holder tendering Old Notes exchanges, assigns and transfers the Old
Notes to the Company and irrevocably constitutes and appoints the Exchange
Agent as the holder's agent and attorney-in-fact to cause the Old Notes to be
assigned, transferred and exchanged. The holder represents and warrants to the
Company and the Exchange Agent that (i) its has full power and authority to
tender, exchange, assign and transfer the Old Notes and to acquire the New
Notes in exchange for the Old Notes, (ii) when the Old Notes are accepted for
exchange, the Company will acquire good and unencumbered title to the Old
Notes, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim, (iii) it will, upon request, execute and
deliver any additional documents deemed by the Company to be necessary or
desirable to complete the exchange, assignment and transfer of tendered Old
Notes and (iv) acceptance of any tendered Old Notes by the Company and the
issuance of New Notes in exchange therefor will constitute performance in full
by the Company of its obligations under the Registration Rights Agreement and
the Company will have no further obligations or liabilities thereunder to such
holders (except with respect to accrued and unpaid Liquidated Damages, if any).
All authority conferred by the holder will survive the death or incapacity of
the holder and every obligation of the holder will be binding upon the heirs,
legal representatives, successors, assigns, executors and administrators of the
holder.


     Each holder will also certify that it (i) is not an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act or that, if it
is an "affiliate," it will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable, (ii) is acquiring
the New Notes in the ordinary course of its business and (iii) has no
arrangement with any person or intent to participate in, and is not
participating in, the distribution of the New Notes.


WITHDRAWAL OF TENDERS


     Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date.


     To withdraw a tender of Old Notes in the Exchange Offer, a telegram telex,
facsimile transmission or letter indicating notice of withdrawal must be
received by the Exchange Agent at its address set forth herein prior to 5:00
p.m., New York City time, on the Expiration Date. Any such notice of withdrawal
must (i) specify the name of the person having tendered the Old Notes to be
withdrawn (the "Depositor"), (ii) identify the Old Notes to be withdrawn
(including the certificate number or numbers and principal amount of such Old
Notes), (iii) be signed by the holder in the same manner as the original
signature on the Letter of Transmittal by which such Old Notes were tendered
(including any required signature guarantees) or be accompanied by documents of
transfer sufficient to have the Trustee with respect to the Old Notes register
the transfer of such Old Notes into the name of the person withdrawing the
tender and (iv) specify the name in which any such Old Notes are to be
registered, if different from that of the Depositor. If Old Notes have been
tendered pursuant to the procedure for book-entry transfer, any notice of
withdrawal must specify the name and number of the account at DTC to be
credited with the withdrawn Old Notes or otherwise comply with DTC's
procedures. All questions as to the validity, form and eligibility (including
time of receipt) of such notices will be determined by the Company, whose
determination shall be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer and no New Notes will be issued with respect thereto unless the
Old Notes so withdrawn are validly retendered. Any Old Notes which have been
tendered but which are not accepted for payment will be returned to the holder
thereof without cost to such holder as soon as practicable


                                       20


after withdrawal, rejection of tender or termination of the Exchange Offer.
Properly withdrawn Old Notes may be retendered by following one of the
procedures described above under "Procedures for Tendering" at any time prior
to the Expiration Date.


UNTENDERED OLD NOTES


     Holders of Old Notes whose Old Notes are not tendered or are tendered but
not accepted in the Exchange Offer will continue to hold such Old Notes and
will be entitled to all the rights and preferences and subject to the
limitations applicable thereto under the Indenture. Following consummation of
the Exchange Offer, the holders of Old Notes will continue to be subject to the
existing restrictions upon transfer thereof and the Company will have no
further obligations to such holders, other than the Initial Purchasers, to
provide for the registration under the Securities Act of the Old Notes held by
them. To the extent that Old Notes are tendered and accepted in the Exchange
Offer, the trading market for untendered and tendered but unaccepted Old Notes
could be adversely affected.


EXCHANGE AGENT


     First Trust National Association, the Trustee under the Indenture, has
been appointed as Exchange Agent of the Exchange Offer. Questions and requests
for assistance, requests for additional copies of this Prospectus or of the
Letter of Transmittal and requests for Notices of Guaranteed Delivery should be

DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION OF
INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE A
VALID DELIVERY.


FEES AND EXPENSES


     The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telephone or in person by officers, regular employees
or agents of the Company and its affiliates.


     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of-pocket expenses in connection therewith
and will pay the reasonable fees and expenses of holders in delivering their
Old Notes to the Exchange Agent.


     The cash expenses of the Company to be incurred in connection with the
Company's performance and completion of the Exchange Offer will be paid by the
Company. Such expenses include fees and expenses of the Exchange Agent and
Trustee, accounting and legal fees and printing costs, among others.


     The Company will pay all transfer taxes, if any, applicable to the
exchange of Old Notes pursuant to the Exchange Offer. If, however, certificates
representing New Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be issued in the name
of, any person other than the registered holder of the Old Notes tendered, or
if tendered Old Notes are registered in the name of any person other than the
person signing the Letter of Transmittal, or if a


                                       21


transfer tax is imposed for any reason other than the exchange of Old Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered holder or any other persons) will be payable
by the tendering holder. If satisfactory evidence of payment of such taxes or
exemption therefrom is not submitted with the Letter of Transmittal, the amount
of such transfer taxes will be billed directly to such tendering holder.


CONSEQUENCES OF FAILURE TO EXCHANGE

     Upon consummation of the Exchange Offer, holders of Old Notes that were
not prohibited from participating in the Exchange Offer and did not tender
their Old Notes will not have any registration rights under the Registration
Rights Agreement with respect to such nontendered Old Notes and, accordingly,
such Old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon. In general, the Old Notes may not be offered
or sold, unless registered under the Securities Act and applicable state
securities laws, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. The
Company does not intend to register the Old Notes under the Securities Act.
Based on interpretations by the staff of the Commission with respect to similar
transactions, the Company believes that the New Notes issued pursuant to the
Exchange Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by any holder of such New Notes (other than any such
holder which is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holder's business, such
holder has no arrangement or understanding with any person to participate in
the distribution of such New Notes and neither the holder nor any other person
is engaging in or intends to engage in a distribution of the New Notes. If any
holder has any arrangement or understanding with respect to the distribution of
the New Notes to be acquired pursuant to the Exchange Offer, the holder (i)
could not rely on the applicable interpretations of the staff of the Commission
and (ii) must comply with the registration and prospectus delivery requirements
of the Securities Act in connection with any resale transaction. Each broker-
dealer that receives New Notes for its own account in exchange for Old Notes
must acknowledge that it will deliver a prospectus in connection with any
resale of its New Notes. See "Plan of Distribution." The New Notes may not be
offered or sold unless they have been registered or qualified for sale under
applicable state securities laws or an exemption from registration or
qualification is available and is complied with. The Company is required, under
the Registration Rights Agreement, to register the New Notes in any
jurisdiction requested by the holders, subject to certain limitations.


OTHER

     Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Old Notes are urged to
consult their financial and tax advisors in making their own decisions on what
action to take.

     Upon consummation of the Exchange Offer, holders of the Old Notes that
were not prohibited from participating in the Exchange Offer and did not tender
their Old Notes will not have any registration rights under the Registration
Rights Agreement with respect to such nontendered Old Notes and, accordingly,
such Old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon. However, in the event the Company fails to
consummate the Exchange Offer or a holder of Old Notes notifies the Company in
accordance with the Registration Rights Agreement that it will be unable to
participate in the Exchange Offer due to circumstances delineated in the
Registration Rights Agreement, then the holder of the Old Notes will have
certain rights to have such Old Notes registered under the Securities Act
pursuant to the Registration Rights Agreement and subject to conditions
contained therein.

     The Company has not entered into any arrangement or understanding with any
person to distribute the New Notes to be received in the Exchange Offer, and to
the best of the Company's information and belief, each person participating in
the Exchange Offer is acquiring the New Notes in it ordinary course of business
and has no arrangement or understanding with any person to participate in the
distribution


                                       22


of the New Notes to be received in the Exchange Offer. In this regard, the
Company will make each person participating in the Exchange Offer aware
(through this Prospectus or otherwise) that if the Exchange Offer is being
registered for the purpose of secondary resale, any holder using the Exchange
Offer to participate in a distribution of New Notes to be acquired in the
registered Exchange Offer (i) may not rely on the staff position enunciated in
Morgan Stanley and Co. Incorporated (available June 5, 1991) and Exxon Capital
Holdings Corporation (available May 13, 1988) or similar letters and (ii) must
comply with registration and prospectus delivery requirements of the Securities
Act in connection with a secondary resale transaction.


ACCOUNTING TREATMENT


     The New Notes will be recorded at the same carrying value as the Old Notes
as reflected in the Company's accounting records on the Exchange Date.
Accordingly, no gain or loss for accounting purposes will be recognized by the
Company. The expenses of the Exchange Offer will be expensed over the term of
the New Notes.


                                       23


                                USE OF PROCEEDS


     The net proceeds from the sale of the Old Notes in the Offering were
approximately $194.2 million (after deducting discounts to the Initial
Purchasers and estimated Offering expenses). The Company will not receive any
proceeds from the Exchange Offer. Approximately $82.4 million of the net
proceeds from the sale of the Old Notes in the Offering was used to repay
outstanding indebtedness under the Credit Facility and the remainder will be
used by the Company for general corporate purposes, including acquisitions,
working capital needs and capital expenditures. See "Description of Certain
Indebtedness."

(1) Amounts have been restated to reflect the 1997 acquisitions of Wilde
    Construction, Inc. and two related companies, and AIDCO, Inc. and one

    Note 2 of Notes to Consolidated Financial Statements.

(2) Includes the results of Burnup & Sims Inc. from March 11, 1994.

(3) Includes the results of Sintel from May 1, 1996.

(4) As a result of the disposal of non-core real estate assets and other
    investments, the Company recorded $23.1 million in special charges in the
    year ended December 31, 1995. See "Management's Discussion and Analysis of
    Financial Condition and Results of Operations."

(5) Income from continuing operations excludes a pro forma adjustment for
    income taxes related to companies which were S corporations and therefore
    not subject to corporate federal income taxes.

(6) EBITDA represents income from continuing operations plus provision for
    income taxes (less the tax effect attributable to minority interests),
    non-recurring or unusual charges, interest expense (net of interest
    income) and depreciation and amortization, less equity in earnings of
    unconsolidated companies (except to the extent of cash dividends
    received). EBITDA is used by management and certain investors as an
    indicator of a company's historical ability to service debt. Management
    believes that an increase in EBITDA is an indicator of the Company's
    improved ability to service existing debt, to sustain potential future
    increases in debt and to satisfy capital requirements. However, EBITDA is
    not intended to represent cash flows for the period, nor has it been
    presented as an alternative to either (i) operating income (as determined
    by generally accepted accounting principles) as an indicator of operating
    performance or (ii) cash flows from operating, investing and financing
    activities (as determined by generally accepted accounting principles) and
    is thus susceptible to varying calculations. EBITDA as presented may not
    be comparable to other similarly titled measures of other companies.

(7) For purposes of determining the ratio of earnings to fixed charges,
    earnings are defined as income from continuing operations before income
    taxes, plus fixed charges. Fixed charges consist of interest expense,
    amortization of debt expense and the estimated interest component of
    rental expense.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


OVERVIEW


     MasTec is one of the world's largest contractors specializing in the
build-out of telecommunications and related infrastructure. The Company's
principal business consists of the design, installation and maintenance of the
outside physical plant for telephone and cable television communications
systems and of integrated voice, data and video local and wide area networks
inside buildings, and the installation of central office telecommunications
equipment. The Company also provides infrastructure construction services to
the electric power industry and other public utilities.


     MasTec was formed in March 1994 through the combination of Church & Tower
Inc. and Church & Tower of Florida, Inc. (collectively, "Church & Tower") and
Burnup & Sims Inc. ("Burnup & Sims"), two established names in the U.S.
telecommunications construction services industry. In April 1996, the Company
purchased Sintel, a company engaged in telecommunications infrastructure
construction services in Spain, Argentina, Chile and Peru, from Telefonica. The
Sintel acquisition gave the Company a significant international presence and
more than doubled the size of the Company in terms of revenue and number of
employees. In Argentina, Chile and Peru, the Company operates through
unconsolidated joint ventures in which it holds a 50% interest. See Notes 2 and
9 of Notes to Consolidated Financial Statements for pro forma financial
information and geographic information, respectively.


     In July and August 1997, the Company acquired Wilde Construction, Inc. and
two related companies and AIDCO, Inc. and one related company (collectively,
the "Pooled Companies") through an exchange of common stock. The acquisitions
were accounted for as poolings of interest. Accordingly, the Company's
consolidated financial statements include the results of the Pooled Companies
for all periods presented. See Note 2 of Notes to Consolidated Financial
Statements.


     In July 1997, the Company acquired a 51% interest in MasTec Inepar, a
Brazilian telecommunications infrastructure construction company. At the time
of the acquisition, MasTec Inepar had a backlog of construction contracts of
approximately $280.0 million. The results of MasTec Inepar are consolidated in
the results of the Company, net of a 49% minority interest, beginning August
1997.


     During the nine months ended September 30, 1997, the Company completed
eight other acquisitions which have been accounted for under the purchase
method of accounting and the results of operations of which have been included
in the Company's consolidated financial statements from the respective
acquisition dates. The Company's pro forma results of operations for 1996 and
for the nine months ended September 30, 1997, giving effect to these
acquisitions, would not differ materially from actual results. In addition,
subsequent to September 30, 1997, the Company completed the acquisition of
Weeks Construction Company.


     On September 3, 1997, Sintel filed a petition with the Spanish labor
authorities to approve a restructuring of its workforce. In response to the
Company's petition, the unionized employees declared work stoppages during the
latter part of September 1997 and continued with half day strikes through the
first week in October 1997. Although only two half days of work stoppages
occurred in the quarter ended September 30, 1997, overall production for the
month of September was further impacted by labor slow downs following the
filing of the petition at the beginning of the month.


     In January 1998, Sintel entered into an agreement with its unions to
resolve the labor dispute, subject to ratification and final documentation. The
agreement contemplates reductions in administrative positions, reductions in
certain non-wage compensation and increases in production benchmarks. The
agreement also contemplates an increase in base wage rates for remaining union
workers. While management anticipates a reduction in ongoing operating costs to
result from the new agreement, the Company recognizes that it services an
increasingly competitive telephony industry in


                                       27


the Spanish market and a substantial portion of any savings may be offset by
more competitive prices to Telefonica and other communication service
customers. There can be no assurance that workers will ratify the agreement or
that final documentation can be completed. As of September 30, 1997, the
Company had not reserved for possible restructuring costs associated with a
settlement of the Sintel labor situation in its consolidated financial
statements.


RESULTS OF OPERATIONS


     Revenue is generated primarily from telecommunications and related
infrastructure services. Infrastructure services are provided to telephone
companies, public utilities, cable television operators, other
telecommunications providers, governmental agencies and private businesses.
Costs of revenue includes subcontractor costs and expenses, materials not
supplied by the customer, fuel, equipment rental, insurance, operations payroll
and employee benefits. General and administrative expenses include management
salaries and benefits, rent, travel, telephone and utilities, professional fees
and clerical and administrative overhead.


     The following table sets forth certain historical consolidated financial
data as a percentage of revenue for the years ended December 31, 1994, 1995 and
1996 and for the nine months ended September 30, 1996 and 1997.

NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED WITH NINE MONTHS ENDED SEPTEMBER
30, 1996


     Revenue from domestic operations increased $61.2 million, or 24.6%, to
$309.8 million for the nine months ended September 30, 1997 as compared to
$248.6 million in the same period in 1996. Domestic growth was generated
primarily by acquisitions. Revenue generated by international operations
increased $83.0 million, or 77.4%, to $190.3 million in the nine months ended
September 30, 1997 as compared to $107.3 million in the comparable period of
1996 due primarily to the inclusion of Sintel's results for the entire period
in 1997 compared to five months in the 1996 period and the results of MasTec
Inepar for two months ended September 30, 1997.


     Gross profit, excluding depreciation and amortization, increased $44.8
million, or 49.3%, to $135.9 million, or 27.2% of revenue, for the nine months
ended September 30, 1997 as compared to $91.1


                                       28


million, or 25.6% of revenue, for the same period in 1996. The increase in
gross profit as a percentage of revenue was due primarily to the performance of
certain higher margin domestic jobs during 1997 and domestic cost reductions.
Domestic gross margins (gross profit as a percentage of revenue) increased to
29.0% for the nine months ended September 30, 1997 from 24.2% in the same
period in 1996. International gross margins decreased to 24.2% for the nine
months ended September 30, 1997 as compared to 28.8% in the same period in 1996
due to overall lower margins from the Company's newly formed Brazilian
operations and lower productivity in the third quarter from the Company's
Spanish operations.


     Depreciation and amortization increased $4.7 million, or 45.6%, to $15.0
million for the nine months ended September 30, 1997 from $10.3 million for the
nine months ended September 30, 1996. The increase in depreciation and
amortization was a result of increased capital expenditures in the latter part
of 1996, as well as depreciation and amortization associated with acquisitions.
As a percentage of revenue, depreciation and amortization was 3.0% and 2.9% of
revenue for 1997 and 1996, respectively.


     General and administrative expenses increased $15.5 million, or 32.6%, to
$63.1 million, or 12.6% of revenue, for the nine months ended September 30,
1997 from $47.6 million, or 13.4% of revenue, for the nine months ended
September 30, 1996. Domestic general and administrative expenses were $34.2
million, or 11.0% of domestic revenue, for the nine months ended September 30,
1997, compared to $29.0 million, or 11.7% of domestic revenue, for the nine
months ended September 30, 1996. The decline as a percentage of domestic
revenue is due primarily to the higher revenue volume. The increase in dollar
amount of domestic general and administrative expenses is due primarily to
acquisitions. International general and administrative expenses increased $10.3
million, or 55.4%, to $28.9 million, or 15.2% of international revenue, for the
nine months ended September 30, 1997 from $18.6 million, or 17.3% of
international revenue, for the nine months ended September 30, 1996. The
increase in international general and administrative expenses was due to the
inclusion of Sintel's results for the entire 1997 period, compared to only five
months during the 1996 period. The decline in international general and
administrative expenses as a percentage of international revenue is due to a
lower general and administrative expense for the Brazilian operations.


     Operating income increased $24.5 million, or 73.6%, to $57.8 million, or
11.6% of revenue, for the nine months ended September 30, 1997 from $33.3
million, or 9.3% of revenue, for the nine months ended September 30, 1996.


     Interest expense decreased to $8.4 million for the nine months ended
September 30, 1997 from $8.6 million for the nine months ended September 30,
1996, primarily due to the lower interest rates on Spanish and domestic
borrowings and the conversion of the Company' s 12% Subordinated Convertible
Debentures into Common Stock on June 30, 1996. Offsetting the decline was the
inclusion of interest expense associated with Sintel's working capital needs
for the entire 1997 period compared to five months for the 1996 period.


     Provision for income taxes on a pro forma basis was $19.3 million, or
36.8% of income from continuing operations before equity in earnings of
unconsolidated companies, taxes and minority interests for the nine months
ended September 30, 1997, compared to $11.1 million, or 37.6% of income from
continuing operations before equity in earnings of unconsolidated companies,
taxes and minority interests for the nine months ended September 30, 1996. The
reduction in the effective tax rate was primarily due to the increased
proportion of income from international operations during the nine month period
in 1997.


     Income from continuing operations on a pro forma basis increased $13.8
million, or 69.7%, from $19.8 million in 1996 to $33.6 million in 1997. Income
from continuing operations on a pro forma basis as a percentage of revenue
increased to 6.7% in 1997 from 5.6% in 1996.


YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995


     Revenue increased $315.2 million, or 144.0%, to $534.1 million for the
year ended December 31, 1996 from $218.9 million for the year ended December
31, 1995. Domestic revenue increased $127.0


                                       29


million, or 58.0%, to $345.9 million for 1996 from $218.9 million for 1995,
primarily due to growth in revenue generated from existing contracts and to an
acquisition completed in 1996. International revenue, comprised of revenue from
Sintel, which the Company acquired in April 1996, contributed $188.2 million of
revenue for the year ended December 31, 1996.


     Gross profit, excluding depreciation and amortization, increased $79.3
million, or 131.5%, to $139.6 million, or 26.1% of revenue, for the year ended
December 31, 1996 from $60.3 million, or 27.5% of revenue, for the year ended
December 31, 1995. Domestic gross margins (gross profit as a percentage of
revenue) decreased to 25.1% for the year ended December 31, 1996 from 27.5% for
the year ended December 31, 1995. The decline in domestic gross margins was
primarily due to additional start-up and expansion costs relating to the rapid
growth in revenue. International gross margins were 28.0% for the year ended
December 31, 1996.


     Depreciation and amortization increased $5.5 million, or 67.1%, to $13.7
million for the year ended December 31, 1996 from $8.2 million for the year
ended December 31, 1995. Domestic depreciation and amortization as a percentage
of domestic revenue decreased to 3.4% for 1996 from 3.7% for 1995 due to
economies of scale obtained over a larger domestic revenue base. International
depreciation and amortization was 1.1% of international revenue for the year
ended December 31, 1996, as the Company's international operations are less
capital intensive than the Company's domestic operations.


     General and administrative expenses increased $43.5 million, or 150.5%, to
$72.4 million, or 13.6% of revenue, for the year ended December 31, 1996 from
$28.9 million, or 13.2% of revenue for the year ended December 31, 1995.
Domestic general and administrative expenses increased $12.5 million, or 43.3%,
to $41.4 million, or 12.0% of domestic revenue, for 1996 from $28.9 million, or
13.2% of domestic revenue in 1995. The decrease in domestic general and
administrative expenses as a percentage of domestic revenue is primarily the
result of spreading overhead expenses over a broader revenue base. Included in
domestic general and administrative expenses for 1996 and 1995 are salaries and
bonuses for employees of the Pooled Companies of approximately $6.1 million and
$3.8 million, respectively. International general and administrative expenses
were $31.0 million, or 16.5% of international revenue, for the year ended
December 31, 1996.


     Operating income increased $30.3 million, or 130.6%, to $53.5 million, or
9.9% of revenue, for the year ended December 31, 1996 from $23.2 million, or
10.6% of revenue, for the year ended December 31, 1995 because of the decline
in domestic gross margins in 1996 and bonuses earned by employees of the Pooled
Companies.


     Interest expense increased $6.6 million, or 124.5%, to $11.9 million for
the year ended December 31, 1996 from $5.3 million for the year ended December
31, 1995 primarily due to borrowings used for equipment purchases and to fund
investments in unconsolidated companies, offset in part by the conversion of
the Company's 12% Subordinated Convertible Debentures into Common Stock on June
30, 1996.


     As a result of the disposal of non-core real estate assets and other
investments, the Company recorded $23.1 million in special charges during the
year ended December 31, 1995.


     Income from continuing operations after a pro forma tax provision
increased to $33.2 million, or 6.2% of revenue, for the year ended December 31,
1996 from $0.2 million for the year ended December 31, 1995 which included a
special charge of $23.1 million.


     In the third quarter of 1995, the Company adopted a plan to dispose of
certain non-core businesses acquired as a result of the acquisition of Burnup &
Sims in March 1994. See Note 13 of Notes to Consolidated Financial Statements.
These businesses included the operations of a printing company, a theater chain
and an uninterrupted power supply assembler. During 1995, the Company sold the
assets of the theater chain and the assembler. The two transactions netted a
gain of $7.4 million after tax. The remaining theater operations have been
closed and are currently being marketed for sale for the


                                       30


underlying real estate value. Based on the estimated net realizable value of
these businesses, a loss on disposition of approximately $6.4 million, net of
tax, relating to the remaining discontinued operations was recorded in 1995.
The Company sold the printing company in January 1997 for its carrying value.
Net assets of discontinued operations and other non-core assets amount to $21.4
million and $14.7 million at December 31, 1996 and September 30, 1997,
respectively, and are reflected in other current assets in the consolidated
balance sheet.


YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994


     Revenue increased $76.3 million, or 53.5%, to $218.9 million for the year
ended December 31, 1995 from $142.6 million for the year ended December 31,
1994, primarily due to expansion into new contract areas and the full year's
effect in 1995 of acquisitions completed in 1994.


     Gross profit, excluding depreciation and amortization, increased $23.2
million, or 62.5%, to $60.3 million, or 27.5% of revenue, for the year ended
December 31, 1995 from $37.1 million, or 26.0% of revenue, for the year ended
December 31, 1994 primarily due to improved operating efficiencies, improved
productivity due to the use of more modern equipment and the renegotiation of
an unprofitable master contract assumed in one of the Company's acquisitions.


     Depreciation and amortization increased $2.7 million, or 49.1%, to $8.2
million for the year ended December 31, 1995 from $5.5 million for the year
ended December 31, 1994 due to a fleet replacement program and an increase in
capital expenditures resulting from expansion into new contract areas. As a
percentage of revenue, depreciation and amortization expense was 3.7% for 1995
and 3.9% for 1994.


     General and administrative expenses increased $8.3 million, or 40.3%, to
$28.9 million, or 13.2% of revenue, for the year ended December 31, 1995 from
$20.6 million, or 14.4% of revenue, for the year ended December 31, 1994.
General and administrative expenses decreased as a percentage of revenue as a
result of spreading overhead expenses over a broader revenue base.


     Operating income increased $12.2 million, or 110.9%, to $23.2 million, or
10.6% of revenue, for the year ended December 31, 1995 from $11.0 million, or
7.7% of revenue, for the year ended December 31, 1994.


     Interest expense increased $1.5 million, or 39.5%, to $5.3 million for the
year ended December 31, 1995 from $3.8 million for the year ended December 31,
1994 primarily due to borrowings used for equipment purchases, to fund a loan
to the holding company of an Ecuadorian cellular phone company and to make
investments in unconsolidated companies.


     As a result of the disposal of non-core real estate assets and other
investments, the Company recorded $23.1 million in special charges during the
year ended December 31, 1995.


     Income from continuing operations after a pro forma tax provision was $0.2
million for the year ended December 31, 1995, compared to income from
continuing operations of $6.8 million, or 4.7% of revenue, for the year ended
December 31, 1994.


FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES


     The Company's primary liquidity needs are for working capital, to finance
acquisitions and capital expenditures and to service the Company's
indebtedness. The Company's primary sources of liquidity have been cash flow
from operations, borrowings under revolving lines of credit and the proceeds
from the sale of investments and non-core assets.


     Net cash provided by operating activities for the nine months ended
September 30, 1997 was $28.5 million, compared to $45.7 million for the nine
months ended September 30, 1996. This decrease was due to an increase in net
income to $36.3 million for the nine months ended September 30, 1997 as


                                       31


compared to net income of $21.1 million in the comparative 1996 period which
was offset by fluctuations in working capital, particularly the reduction of
accounts payable balances and an increase in accounts receivable from Brazilian
operations. Net cash provided by operating activities for the years ended
December 31, 1996, 1995 and 1994 was $41.9 million, $7.9 million and $4.3
million, respectively.


     Net cash provided by the sale of investments and non-core assets amounted
to $9.8 million in the nine months ended September 30, 1997. Net cash provided
by the sale of investments and non-core assets amounted to $9.4 million, $24.3
million and $0.7 million in the years ended December 31, 1996, 1995 and 1994,
respectively. The Company invested cash, net of cash acquired, in acquisitions
and investments in unconsolidated companies totaling $26.9 million during the
nine months ended September 30, 1997, $6.8 million in 1996 and $9.0 million in
1995, and in 1994 had a net inflow from acquisitions of $4.7 million. During
the nine months ended September 30, 1997, the Company made capital expenditures
of $17.2 million, primarily for machinery and equipment used in the production
of revenue. Capital expenditures were $8.4 million, $17.2 million and $6.0
million in the years ended December 31, 1996, 1995 and 1994, respectively. The
Company believes that capital expenditures in 1998, excluding capital
expenditures resulting from acquisitions, will not exceed $30.0 million.


     As of September 30, 1997, working capital totaled $133.2 million, compared
to working capital of $136.2 million at December 31, 1996, excluding a note
receivable that was converted into an equity investment in June 1997. See Note
2 of Notes to Consolidated Financial Statements. Included in working capital
are net assets of discontinued operations and real estate held for sale
totaling $14.7 million.


     In December 1997, the Company sold its indirect investment in Consorcio
Ecuatoriano de Telecomunicaciones, S.A. ("Conecel"), an Ecuadorian cellular
phone company, for $20.0 million in cash and the right to receive shares of
Conecel non-voting common stock upon a public offering by Conecel. The Company
will have certain registration rights with respect to the Conecel common stock
that it will receive.


     The Company continues to pursue a strategy of growth through acquisitions
and internal expansion. During the quarter ended September 30, 1997, the
Company closed its acquisition of 51% of MasTec Inepar for stock and $29.4
million in cash payable over eleven months. In addition, in connection with its
acquisition of Sintel, the Company is required to make payments of 1.8 billion
pesetas (approximately $12.1 million at the exchange rate in effect at the time
of the acquisition) on each of December 31, 1997 and 1998. The Company has paid
a portion of the December 31, 1997 payment, with the remaining amounts to be
paid pending resolution of offsetting amounts between the Company and
Telefonica. See Note 2 of Notes to Consolidated Financial Statements. The
Company believes that cash generated from operations, borrowings under its
Credit Facility and proceeds from the sale of investments and non-core assets
will be sufficient to finance these payments, as well as the Company's working
capital needs, capital expenditures and debt service obligations for the
foreseeable future. Future acquisitions are expected to be financed from these
sources, as well as other external financing sources to the extent necessary,
including the issuance of equity securities and additional borrowings.


     In June 1997, the Company refinanced its domestic credit facility with the
$125.0 million Credit Facility. Borrowings under this facility may be used for
domestic acquisitions, working capital, capital expenditures and general
corporate purposes. At September 30, 1997, borrowings under this facility
totaled $82.4 million and standby letters of credit issued pursuant to this
facility totaled approximately $3.5 million, and approximately $39.0 million
remained unused and available. The Company used a portion of the proceeds from
the Offering to repay all outstanding borrowings under the Credit Facility.
After giving effect to the Offering and the application of the net proceeds
therefrom, the Company had approximately $121.5 million of borrowings available
under the Credit Facility. The Credit Facility contains certain covenants
which, among other things, restrict the payment of dividends, limit the
Company's ability to incur additional debt, create liens, dispose of assets,
merge or consolidate with another entity or make other investments or
acquisitions, and provide that the Company must maintain


                                       32


minimum amounts of stockholders' equity and financial ratio coverages. See
"Description of Certain Indebtedness" and Note 5 of Notes to Consolidated
Financial Statements.


     The Company conducts business in several foreign currencies that are
subject to fluctuations in the exchange rate relative to the U.S. dollar. The
Company does not enter into foreign exchange contracts. It is the Company's
intent to utilize foreign earnings in the foreign operations for an indefinite
period of time and only repatriate those earnings when it is considered cost
effective. In addition, the Company's results of operations from foreign
activities are translated into U.S. dollars at the average prevailing rates of
exchange during the period reported, which average rates may differ from the
actual rates of exchange in effect at the time of the actual conversion into
U.S. dollars. The Company currently has no plans to repatriate significant
earnings from its international operations.


     The Company's current and future operations and investments in certain
foreign countries are generally subject to the risks of political, economic or
social instability, including the possibility of expropriation, confiscatory
taxation, hyper-inflation or other adverse regulatory or legislative
developments, or limitations on the repatriation of investment income, capital
and other assets. The Company cannot predict whether any of such factors will
occur in the future or the extent to which such factors would have a material
adverse effect on the Company's international operations.


SEASONALITY


     The Company's domestic operations have historically been seasonally weaker
in the first and fourth quarters of the year and have produced stronger results
in the second and third quarters. Sintel has experienced seasonal weakness in
the first quarter, but has produced relatively strong results in the fourth
quarter. This seasonality is primarily the result of customer budgetary
constraints and preferences and, to a lesser extent, the effect of winter
weather on outside plant activities. Certain U.S. customers, particularly the
RBOCs, tend to complete budgeted capital expenditures before the end of the
year and defer additional expenditures until the following budget year.
Telefonica, the Company's principal international customer, has historically
rushed to complete budgeted expenditures in the last quarter. Revenue
anticipated from the Company's newly formed Brazilian operations, MasTec
Inepar, are not expected to fluctuate seasonally.


IMPACT OF INFLATION


     The primary inflationary factor affecting the Company's operations is
increased labor costs. Although the Company has not experienced significant
increases in labor costs to date, the low unemployment rate in the United
States has made it more difficult to find qualified personnel at low cost in
some areas where the Company operates. Continued shortages of labor could
increase labor costs for the Company in the future.

                                   BUSINESS


GENERAL


     MasTec is one of the world's largest contractors specializing in the
design, installation and maintenance of infrastructure for the rapidly growing
telecommunications industry. The Company focuses on the installation of aerial
and underground copper, coaxial and fiber optic cable networks as well as
wireless antenna networks ("outside plant services"). The Company believes it
is the largest independent contractor for these systems in the United States
and Spain, and one of the largest in Argentina, Brazil, Chile and Peru. The
Company also installs central office switching equipment, and designs, installs
and maintains integrated voice, data and video local and wide area networks
inside buildings ("inside wiring"). Clients for the Company's services include
major domestic and international telecommunications service providers such as
the RBOCs, other local exchange carriers, competitive access providers, cable
television operators, long-distance operators and wireless phone companies.
MasTec believes it is well positioned to benefit from the significant growth
taking place in the global telecommunications market.


     MasTec has experienced significant and consistent growth as a result of
its ability to identify and integrate strategic acquisitions, its competitive
position as one of the largest providers of infrastructure services and
favorable trends in the telecommunications industry. The Company's revenue has
increased from $142.6 million in 1994 to $534.1 million in 1996 and from $355.8
million for the first nine months of 1996 to $500.1 million for the same period
in 1997. EBITDA has also increased from $18.2 million in 1994 to $71.2 million
in 1996 and from $46.1 million in the first nine months of 1996 to $74.0
million in the same period in 1997. The Company expects to continue to grow
through additional strategic acquisitions as well as through internal
expansion. Since January 1996, the Company has completed 13 domestic and two
foreign acquisitions and actively continues to pursue complimentary
acquisitions in the highly fragmented telecommunications infrastructure
industry. Internal growth is expected to be driven by the expansion of the
global telecommunications industry resulting from (i) continued global
deregulation, which is allowing numerous new service providers to enter the
marketplace and is increasing the competitive pressure on existing participants
to upgrade and expand their networks; (ii) increasing consumer demand for
advanced communications services which require the upgrading of existing
infrastructure to handle increased bandwidth needs; and (iii) increasing
reliance on outsourcing of infrastructure needs to full service contractors by
service providers in an effort to reduce costs and focus on their core
competencies.


COMPETITIVE STRENGTHS


     The Company seeks to differentiate itself from its competitors through the
following characteristics:


     STRONG CUSTOMER RELATIONSHIPS. Founded in 1929, the Company has developed
strong relationships with numerous telecommunications service providers by
providing high quality services in a cost and time efficient manner. The
Company has been providing services to Telefonica and BellSouth, its two
largest customers, since 1950 and 1969, respectively, and maintains similar
long-term relationships with many of its other customers. MasTec currently has
23 multi-year service contracts with Telefonica, the RBOCs and other
telecommunications service providers for certain of their outside plant
requirements up to a specific dollar amount per job and within certain
geographic areas.


     DIVERSE CUSTOMER BASE. MasTec provides a full range of infrastructure
services to a diverse customer base. Domestically, the Company provides outside
plant services to local exchange customers such as BellSouth, US West
Communications, Inc., SBC Communications, Inc., United Telephone Company of
Florida, Inc. (a subsidiary of Sprint) and GTE Corporation. The Company also
provides outside plant services to competitive local exchange carriers such as
MFS Communications Company, Inc., Sprint Metropolitan Networks, Inc. and MCI
Metro, Inc. (the local telephone subsidiaries of Sprint and MCI, respectively),
cable television operators such as Time Warner Inc., Cox Communications, Inc.


                                       34


and Marcus Cable Company, long distance carriers such as MCI and Sprint, and
wireless communications providers such as PrimeCo Personal Communications LP
and Sprint Spectrum, L.P. Internationally, the Company provides outside plant
services, turn-key switching systems installation and inside wiring services
primarily to Telefonica, the principal telephone company in Spain, and
Telefonica's affiliates in Argentina, Chile and Peru. In July 1997, the Company
also began servicing the local telephone subsidiaries of Telebras, the
Brazilian government-owned telecommunications system, in Sao Paulo, Rio de
Janeiro, Parana and other states in the more populous and developed Southern
region of Brazil, as well as CRT, the local telephone company in Rio Grande do
Sul which is partly owned by Telefonica.


     The Company renders inside wiring services nationwide to large corporate
customers with multiple locations such as First Union National Bank, IBM and
Dean Witter Reynolds Inc., and to universities and health care providers.


     TURN-KEY CAPABILITIES. The Company believes it is one of the few
contractors capable of providing all of the design, installation and
maintenance services necessary for a cable or wireless network starting from a
transmission point, such as a central office or headend, and running
continuously through aerial and underground cables to the ultimate end users'
voice and data ports, cable outlets or cellular stations. The Company can also
install the switching devices at a central office or set up local and wide area
voice, data and video networks to expand a business's telecommunications
infrastructure both inside a specific structure or between multiple structures.
 


     The Company believes that its customers increasingly are seeking
comprehensive solutions to their infrastructure needs by turning to fewer
qualified contractors who have the size, financial capability and technical
expertise to provide a full range of infrastructure services. The Company
believes that this trend will accelerate as industry consolidations increase
and as these consolidated entities begin to provide bundled services to end
users. The Company believes it has positioned itself through acquisitions and
internal growth as a full service provider of outside plant and inside wiring
infrastructure services to take advantage of this trend.


     BROAD GEOGRAPHIC PRESENCE. The Company has significantly broadened its
geographic presence in recent years through strategic acquisitions.
Domestically, MasTec has expanded beyond its historical base in the
Southeastern United States and currently has operations in over 30 states in
the Southeast, Southwest, West and upper Midwest regions of the country. The
Company also substantially increased its international operations through the
acquisition, in April 1996, of Sintel, the largest telecommunications
infrastructure contractor in Spain, and through the acquisition, in July 1997,
of a majority interest in MasTec Inepar, a leading telecommunications
construction company in Brazil. Due to its broad geographic presence, the
Company believes that it is well suited to service customers with operations
across the United States as well as companies who are active in multiple areas
of the world such as multinational corporations and telecommunications service
providers that are expanding into international markets. In addition, by
developing business in many geographic regions, the Company believes it is less
susceptible to changes in the market dynamics in any one region.


GROWTH STRATEGY


     The Company is pursuing a disciplined strategy of growth and
diversification in its core business through strategic acquisitions and
internal expansion as follows:


     STRATEGIC ACQUISITIONS. The Company plans to continue to pursue strategic
acquisitions in the fragmented telecommunications and utility infrastructure
industry that either expand its geographic coverage and customer base or
broaden the range of services it can offer to clients. The Company focuses its
acquisition efforts primarily on companies with successful track records and
strong management. The Company has acquired 15 companies since January 1996 and
has significant experience in identifying, purchasing and integrating
telecommunications infrastructure businesses both domestically and
internationally. Management believes that MasTec is able to improve the
acquired


                                       35


companies' operating performance by providing strategic guidance,
administrative support, greater access to capital and savings in purchasing and
insurance costs.


     INTERNAL EXPANSION. The Company believes it is poised to capitalize on the
anticipated growth in its industry due to its status as one of the world's
largest telecommunications infrastructure contractors and its strong customer
relationships. The International Telecommunications Union estimates that
between 1996 and 2000 telecommunications infrastructure investment will exceed
$50 billion in the United States and $600 billion worldwide. In addition, the
Company believes that the RBOCs and other utilities in the United States, which
still conduct a significant portion of their construction work in-house, will
out-source more infrastructure construction in the future in response to
competitive pressures to cut costs, streamline their operations and focus on
their core competencies. The Company believes that its reputation for quality
and reliability, operating efficiency, financial strength, technical expertise,
presence in key geographic areas and ability to offer a full range of
construction services make it well positioned to compete for this business,
particularly the larger, more technically complex infrastructure projects.


     The Company also anticipates that its Brazilian operations will become a
more significant part of its operations. MasTec Inepar, in its first two months
of operations ended September 30, 1997, generated revenue and EBITDA (net of
minority interests) of $35.0 million and $2.7 million, respectively, and at
September 30, 1997 had a backlog of approximately $245.0 million. The Brazilian
government has estimated that approximately $75 billion will need to be
invested over a seven year period in order to modernize and expand Brazil's
telecommunications infrastructure. To accomplish this objective, the government
has stated its intention of deregulating and privatizing Brazil's
telecommunications system. The Company believes that, through MasTec Inepar, it
is well positioned to participate in this anticipated expansion.


     In addition to focusing on its core telecommunications customers, the
Company plans to achieve incremental growth by continuing to develop
complementary lines of businesses. These businesses include the provision of
premise wiring services to corporations and infrastructure construction
services to the electric power industry and other public utilities.


SERVICES, MARKETS AND CUSTOMERS


TELECOMMUNICATIONS CONSTRUCTION--UNITED STATES OPERATIONS


     OUTSIDE PLANT CONSTRUCTION. The Company's principal domestic business
consists of outside plant services for telecommunications providers, including
incumbent and competitive local exchange carriers, cable television operators,
long-distance carriers and wireless communications providers. Outside plant
services consist of all of the services necessary to design, install and
maintain the physical facilities used to provide telecommunications services
from the provider's central office, switching center or cable headend to the
ultimate consumer's home or business. These services include the placing and
splicing of cable, the excavation of trenches in which to place the cable, the
placing of related structures such as poles, anchors, conduits, manholes,
cabinets and closures, the placing of drop lines from the main transmission
lines to the customer's home or business, and the maintenance and removal of
these facilities. The Company has developed expertise in directional boring, a
highly specialized and increasingly common method of placing buried cable
networks in congested urban markets without digging a trench.


     The Company provides a full range of outside plant services to its
telecommunications company customers, although certain of the Company's
customers, principally the RBOCs, handle certain of these services in-house.
The Company's customers generally supply materials such as cable, conduit and
telephone equipment, and the Company provides the expertise, personnel, tools
and equipment necessary to perform the required installation and maintenance
services.


     The Company currently provides outside plant services primarily to
customers in Alabama, Alaska, Arizona, California, Colorado, Florida, Georgia,
Iowa, Kansas, Michigan, Minnesota, Montana,


                                       36


Nebraska, North Carolina, North Dakota, South Dakota, South Carolina,
Tennessee, Texas, Virginia and Wyoming. Principal customers for
telecommunications outside plant services include BellSouth, US West
Communications, Inc., SBC Communications, Inc., the long distance and local
exchange subsidiaries of both MCI and Sprint, GTE Corp., MFS Communications
Company, Inc., Time Warner Inc., Cox Communications, Inc. and Marcus Cable
Company.


     Services rendered to the Company's incumbent local exchange customers are
performed primarily under master contracts, which typically are exclusive
service contracts to provide all of the carrier's outside plant requirements up
to a specified dollar amount per job and within certain geographic areas. These
contracts generate revenue ranging between $3.0 million and $30.0 million over
their respective terms, generally two to three years. Such contracts are
typically subject to termination at any time upon 90 to 180 days prior notice
to the Company. Each master contract contemplates hundreds of individual
construction and maintenance projects generally valued at less than $100,000
each. These contracts typically are awarded on a competitive bid basis,
although customers are sometimes willing to negotiate contract extensions
beyond their original terms without opening them up to bid. The Company
currently has 20 master contracts with telecommunications customers covering
defined regions within the United States.


     In addition to services rendered pursuant to master contracts, the Company
provides outside plant services on individual projects awarded on a competitive
bid basis or through individual negotiation. While such projects generally are
substantially larger than the individual projects covered by master contracts,
they typically require the provision of services identical to those rendered
under master contracts.


     The Company also provides turn-key site acquisition, design, installation
and maintenance services to the wireless communications industry, including
site acquisition and preparation, design and construction of communications
towers, placement of antennas and associated wiring, and construction of
equipment huts.


     INSIDE PREMISES CONSTRUCTION. The Company provides design, installation
and maintenance of integrated voice, data and video networks inside buildings
for large companies with multiple locations such as First Union National Bank,
IBM and Dean Witter Reynolds Inc., for college campuses such as the University
of California at Riverside and the University of Miami and for health care
providers such as Carolina Medical Center and Kaiser Permanente. The Company
provides these services primarily on the east and west coasts of the United
States although the Company is capable of providing these services nationwide.


     Inside wiring services consist of designing, installing and maintaining
local area networks and wide area networks linking the customers' voice
communications networks at multiple locations with their data and video
services. This type of work is similar to outside plant construction; both
involve the placing and splicing of copper, coaxial and fiber optic cables.
Inside wiring is less capital intensive than outside plant construction but
requires a more technically proficient work force.


     The Company contracts with primary contractors to provide services to
First Union National Bank and IBM under subcontracts that are similar to master
contracts in the outside plant business because they grant the Company the
exclusive right to provide inside wiring to these customers within certain
geographic regions. The Company also provides inside wiring services on
individual projects that are awarded on a competitive bid basis or through
individual negotiation. The Company intends to take advantage of the
fragmentation of the inside wiring industry by marketing a full range of inside
wiring services to large corporations with multiple locations across the
country. Increasingly, these types of customers are seeking a single vendor to
provide all of their inside wiring; First Union National Bank, for example,
used more than 30 different vendors to provide the services that the Company
now provides. The Company also provides inside premises electrical wiring to
private customers, principally real estate developers.


     The Company is one of two distributors in the United States, Canada and
Mexico of a fiber optic cable installation technology known as FutureFlex. This
technology allows the installation of individual


                                       37


strands of optical fiber by means of compressed gas blown through flexible
tubing without the necessity of cutting or splicing the cable except at the
terminal points. As a result, the network can be expanded, changed or moved
more easily and cost-effectively.


TELECOMMUNICATIONS CONSTRUCTION--INTERNATIONAL OPERATIONS


     OVERVIEW. The Company is engaged in the telecommunications construction
business internationally primarily in Argentina, Brazil, Chile, Peru and Spain
through Sintel and its affiliates and MasTec Inepar. Sintel is a Spanish
company that has provided telecommunications construction services to
Telefonica and Telefonica's affiliates since 1950. Telefonica is the principal
provider of local and long distance telephony in Spain. Through its affiliate,
Telefonica Internacional, S.A., Telefonica owns interests in certain local
telephone companies in Argentina, Brazil, Chile and Peru. Through Sintel, the
Company is the leading provider of telecommunications infrastructure services
to Telefonica and its affiliates in Spain, and one of the leading providers of
these services to Telefonica's affiliates in Argentina, Chile and Peru.


     The Company renders telecommunications construction services in Brazil
through MasTec Inepar, a Brazilian company owned 51% by the Company and 49% by
Inepar SA Industrias e Construcoes ("Inepar"), a leading telecommunications and
power company in Brazil. MasTec Inepar was formed in July 1997 to take
advantage of construction opportunities created by the privatization, de-
monopolization and deregulation of the Brazilian telecommunications market.


     SPANISH OPERATIONS. In Spain, Sintel's principal business is providing
outside plant, inside wiring services and equipment installation to Telefonica
and its affiliates. These services are substantially similar to those provided
by the Company in the United States. Sintel also installs Telefonica telephone
equipment in residences and businesses. Sintel subcontracts certain outside
plant services to reduce personnel expenses and to minimize investment in
equipment. Sintel's Spanish operations are concentrated in Spain's largest
commercial centers, Madrid, Barcelona, Seville and Valencia, and surrounding
areas, although Sintel maintains a presence throughout Spain.


     Sintel provides the largest percentage of Telefonica's outside plant
services requirements. Sintel provides the bulk of these services under three
separate multi-year comprehensive services contracts, which are similar to
master contracts in the United States, for distinct types of outside plant
services: (i) placement and splicing of communications lines; (ii) trenching
and placing of conduits; and (iii) placing of drop lines to residences and
businesses. These agreements set the unit prices at which Sintel will render
services to Telefonica and establish the percentage of Telefonica's
requirements in these categories that will be satisfied by Sintel in particular
geographic areas of Spain. Telefonica enters into similar agreements with
Sintel's principal competitors in Spain. The Company believes that Telefonica
considers various factors in awarding these contracts and setting their terms,
including price, quality, technical proficiency and the contractor's
relationship with Telefonica. Telefonica also awards individual projects
through a competitive bidding process or through individual negotiation.


     In recent years, Telefonica has reduced the number of contractors with
which it will enter into comprehensive services agreements. Because of Sintel's
historical relationship with Telefonica, the Company believes that Sintel will
continue to be a leading provider of these services to Telefonica in Spain.


     In addition to outside plant services, Sintel provides inside wiring
services to Telefonica that are substantially similar to those provided by the
Company in the United States. Sintel also installs transmission equipment,
central office switching equipment, power generating equipment and cellular
equipment for telecommunications systems for Telefonica. This equipment
includes multiplexers, carrier systems and microwave systems, and central
office equipment such as frames, protectors, connector blocks, batteries and
power systems, and cellular antennas and cell sites. The contracts for this
work are awarded on a competitive bid basis or through individual negotiation.


     Telefonica is the principal provider of local and long distance telephony
in Spain. As a result of European Union initiatives, Spain must liberalize its
telecommunications industry by December 1, 1998


                                       38


to permit competitors to Telefonica. In July 1997, a second license to provide
public switched telephony was awarded to Retevision, S.A. ("Retevision"), which
is owned partly by the Spanish government, Societa Finanziaria Telefonica per
Azioni SpA ("STET"), an Italian telephone company, and Empresa Nacional de
Electricidad, S.A., a Spanish electric utility company. Retevision is expected
to begin providing local telephony in Spain in 1998, during which a third local
and long distance telephony license is expected to be awarded. By December 1,
1998, it is expected that the industry will be completely open to competition.
The Company believes that the increased competition in the Spanish telephony
market will increase demand for outside plant services in Spain as new service
providers build competing networks.


     Sintel also installs and maintains cable television networks for
Telefonica and its affiliates and for Retevision. The Spanish cable television
market has been underdeveloped due to the lack of a legal structure for the
provision of cable telecommunications services in Spain. In 1997, a legal
structure for the provision of these services was completed and five new
licenses to provide cable television services have been awarded and
applications for an additional 18 licenses are pending. In addition, in 1998,
cable operators will be entitled to provide local telephony within their
service areas as well as long distance telephony. The Company anticipates that
the demand for construction services to the cable television industry will
increase significantly as new networks are constructed and existing networks
are upgraded.


     Sintel's workers have engaged in partial work stoppages in protest of a
petition filed by Sintel for a further work force restructuring. See "Risk
Factors--Sintel Labor Relations."


     LATIN AMERICAN OPERATIONS. Sintel operates in Argentina, Chile and Peru
through unconsolidated subsidiaries in which Sintel holds a 50% interest. The
other 50% interests in these subsidiaries are held by established local
infrastructure construction companies and operational control is shared by the
Company and its local partner. In Argentina and Chile, the Company's partners
are subsidiaries of Sociedad Macri, one of the largest commercial groups in
Argentina. In Peru, the Company's partner is a subsidiary of Grana y Montero,
S.A., a leading construction company in Peru. The principal shareholder of
Grana y Montero, S.A., is a shareholder and a director of Telefonica del Peru.
Sintel's Latin American affiliates primarily provide outside plant services,
cable television installation and similar services to Telefonica's local
telephone company affiliate in each of the countries in which the Sintel
affiliate is located: Telefonica de Argentina in Argentina; Compania de
Telefonos de Chile in Chile; and Telefonica del Peru in Peru. As part of the
agreement with Sociedad Macri for the acquisition of its interest in Sintel's
Argentine affiliate, Sociedad Macri has contributed to the affiliate certain of
its telecommunications construction contracts with Telecom de Argentina, S.A.,
the principal provider of local telephony in northern Argentina.


     BRAZILIAN OPERATIONS. MasTec Inepar, a Brazilian company, was formed in
June 1997 by the Company and Inepar. As part of the formation, Inepar
transferred the personnel, qualifications and other assets of its
telecommunications construction division to MasTec Inepar together with
contracts for specific projects with prices totalling approximately $280
million. These contracts cover the provision of outside plant services for the
local exchange subsidiaries of Telebras, the Brazilian government-owned
telecommunications company, particularly in Sao Paulo, Rio de Janeiro, Parana
and other states in the more populous and developed southern region of Brazil.
MasTec Inepar also provides services to CRT, the local telephone company in Rio
Grande do Sul which is partly owned by Telefonica. In addition, MasTec Inepar
is seeking to provide construction services to certain of the consortia that
recently were awarded B-band cellular concessions in Brazil. BellSouth, one of
the Company's largest domestic customers, is one of the leading members of a
consortium that won the concession to provide B-band cellular services to two
of the ten regions of Brazil recently opened for public bid, including the
region comprising Sao Paulo, the world's third-largest city.


INFRASTRUCTURE CONSTRUCTION FOR PUBLIC UTILITIES


     The Company provides infrastructure construction services to electric
power companies and other public utilities, including the City of Austin
Electric Department, City Public Service of San Antonio,


                                       39


Duke Energy Corporation, Florida Power and Light Company, Florida Power
Corporation, Jacksonville Electric Authority, Memphis Light, Gas and Water
Division, Texas Utilities Company, Carolina Power & Light Co., and Georgia
Power Co., and a number of regional electrical cooperatives. These services,
which are substantially similar to the outside plant services provided to
telecommunications companies, include directional boring for conduit and pipes,
trenching, placing of electric cables, and restoring asphalt and concrete
surfaces. Services to many of these customers are provided under exclusive
master contracts with two to three year initial terms expiring at various
dates.


SALES AND MARKETING


     Executives of the Company's outside plant subsidiaries market outside
plant services to existing and potential telecommunications and other utility
customers in order to be placed on lists of vendors invited to submit bids for
master contracts and individual construction projects. Inside premises services
are marketed both by the executives of the subsidiaries that provide these
services and through commissioned salespeople employed by the Company.


TELECOMMUNICATIONS INVESTMENTS AND OTHER ASSETS


     The Company has invested in certain telecommunications businesses located
in or servicing Latin America. These include minority interests in Supercanal
Holding, S.A. ("Supercanal") and related entities, which operate a cable
television system in Argentina, and in Conecel, an Ecuadorian cellular company.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations."


     The Company owns several assets in the United States that are unrelated to
its core construction business and that it intends to sell. Among these assets
are approximately 1,000 acres of unimproved land in Florida, four non-operating
drive-in theaters located in central and southwest Florida, and a pre-cast
concrete manufacturing facility in Charlotte, North Carolina. All of these
properties were assets of entities acquired by the Company. The Company is
actively attempting to dispose of all of these assets to concentrate its
resources on its core telecommunications and related construction businesses.


SUPPLIERS


     The Company's customers supply the majority of the raw materials and
supplies necessary to carry out the Company's contracted work. The Company is
not dependent on any one supplier for any raw materials or supplies that the
Company obtains for its own account other than the FutureFlex airblown fiber
product that the Company distributes for Sumitomo Electric Lightwave Co.


COMPETITION


     The industry in which the Company competes is highly competitive and
fragmented. The Company competes with a number of contractors in the markets in
which it operates, ranging from small independent firms servicing local markets
to larger firms servicing regional markets as well as with large national and
international equipment vendors on turn-key projects who subcontract
construction work to contractors other than the Company. These equipment
vendors typically are better capitalized and have greater resources than the
Company. Most companies engaged in the same or similar business tend to operate
in a specific, limited geographic area, although larger competitors may bid on
a particular project without regard to location. Although the Company believes
it is the largest provider of infrastructure services to the telecommunications
and other utilities industries in the United States and Spain and one of the
largest in Argentina, Brazil, Chile and Peru, neither the Company nor any of
its competitors can be considered dominant in the industry on a national or
international basis. The Company also faces competition from the in-house
construction and maintenance departments of RBOCs and other customers and
potential customers, which employ personnel who perform some of the same types
of services as those provided by the Company.


                                       40


EMPLOYEES


     As of September 30, 1997, the Company (excluding its unconsolidated
companies) had approximately 7,400 employees, 4,300 of whom are employed in
domestic operations and 3,100 of whom are employed in international operations.
Approximately 150 of the Company's domestic employees and approximately 2,300
of Sintel's employees are unionized. See "Risk Factors--Sintel Labor Relations"
for a description of the current state of labor relations at Sintel.


PROPERTIES


     The Company's corporate headquarters are located in a 60,000 square foot
building owned by the Company in Miami, Florida. The Company also has regional
offices in owned facilities located in Tampa, Florida, Austin, Texas and
Charlotte, North Carolina. Sintel's principal executive offices are located in
leased premises in Madrid, Spain and MasTec Inepar's principal executive
offices are located in leased premises in Sao Paulo, Brazil.


     The Company's principal operations are conducted from field offices,
equipment yards and temporary storage locations, none of which the Company
believes is material to its operations because most of the Company's services
are performed on the customers' premises or on public rights of way. In
addition, the Company believes that equally suitable alternative locations are
available in all areas where it currently does business.


LEGAL PROCEEDINGS


     In December 1990, Albert H. Kahn, a stockholder of the Company, filed a
class action and derivative suit in Delaware state court against the Company,
the then-members of its Board of Directors and National Beverage Corporation
("NBC"), the Company's then-largest stockholder. The complaint alleges, among
other things, that the Company's Board of Directors and NBC breached their
respective fiduciary duties in approving certain transactions, including the
distribution in 1989 to the Company's stockholders of all of the common stock
of NBC owned by the Company and the exchange by NBC of shares of common stock
of the Company for certain indebtedness of NBC to the Company. The lawsuit
seeks to rescind these transactions and to recover damages in an unspecified
amount.


     In November 1993, Mr. Kahn filed a class action and derivative complaint
against the Company, the then-members of its Board of Directors, Church &
Tower, Inc. (the Company's predecessor) and Jorge L. Mas, Jorge Mas and Juan
Carlos Mas, as the then principal shareholders of Church & Tower, Inc. The
lawsuit alleges, among other things, that the Company's Board of Directors and
NBC breached their respective fiduciary duties by approving the terms of the
acquisition of the Company by the Mas family, and that Church & Tower, Inc. and
its principal shareholders had knowledge of the fiduciary duties owed by NBC
and the Company's Board of Directors and knowingly and substantially
participated in the breach of these duties. The lawsuit also claims
derivatively that each member of the Company's Board of Directors engaged in
mismanagement, waste and breach of fiduciary duties in managing the Company's
affairs prior to the acquisition by the Mas family.


     The Company believes that the allegations in each of these lawsuits are
without merit and intends to defend these lawsuits vigorously.


     In November 1997, Church & Tower filed a lawsuit against Miami-Dade County
(the "County") in the Circuit Court of the Eleventh Judicial Circuit in and for
Dade County, Florida alleging breach of contract and seeking damages in
connection with the County's refusal to pay amounts due to Church & Tower under
a multi-year agreement to perform road restoration work for the Miami-Dade
Water and Sewer Department ("MWSD"), a department of the County, and the
County's wrongful termination of the agreement. The County has refused to pay
amounts due to Church & Tower under the agreement until alleged overpayments
under the agreement have been resolved. The County has also refused to award a
new road restoration agreement for MWSD to Church & Tower, which was the low
bidder for


                                       41


the new agreement. The Company believes that any amounts due to the County
under the existing agreement are not material and may be recoverable in whole
or in part from Church & Tower subcontractors who actually performed the work
and whose bills were submitted directly to the County.


     The Company is a party to other pending legal proceedings arising in the
normal course of business, none of which the Company believes is material to
the Company's financial position or results of operations.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS


     The following is a summary of certain indebtedness of the Company.


CREDIT FACILITY


     The Company and its principal domestic subsidiaries maintain a $125.0
million revolving credit facility with a syndicate of banks led by BankBoston,
N.A. (the "Credit Facility"). The Company may use borrowings under the Credit
Facility for acquisitions, capital expenditures, working capital and general
corporate purposes, subject to certain restrictions. The Credit Facility
expires on June 9, 2000 unless extended until no later than June 9, 2002 as
provided in the Credit Facility. Interest on amounts outstanding under the
Credit Facility bear interest at a rate per annum equal to the prime rate, as
announced by BankBoston, N.A., or at the Company's option, LIBOR plus the
applicable LIBOR margin, currently 1.00%. The Credit Facility is secured by a
pledge of the stock of the Company's principal domestic subsidiaries as well as
a portion of the stock of Sintel. At September 30, 1997, borrowings under this
facility totaled $82.4 million. The Company used a portion of the proceeds of
the Offering to repay all outstanding borrowings under the Credit Facility, as
a result of which approximately $121.5 million of borrowings were available
under the Credit Facility.


     The Credit Facility contains certain covenants which, among other things,
restrict the payment of dividends, limit the Company's ability to incur
additional debt, create liens, dispose of assets, merge or consolidate with
another entity or make other investments or acquisitions, and provide that the
Company must maintain minimum amounts of stockholders' equity and financial
ratio coverages.


SPANISH PESETA DENOMINATED DEBT


     Sintel maintains a revolving credit facility denominated in pesetas with a
wholly-owned finance subsidiary of Telefonica (the "Sintel Facility"). At
September 30, 1997, borrowings under the Sintel Facility totaled approximately
2.2 billion pesetas ($14.7 million at the exchange rate on September 30, 1997).
Sintel may use borrowings under this facility for working capital and other
general corporate purposes. Amounts outstanding under the Sintel Facility bear
interest at a rate per annum equal to the Madrid Interbank Offered Rate plus
0.30%. The Sintel Facility is unsecured. Sintel also maintains other peseta
denominated credit facilities with certain other Spanish financial
institutions. At September 30, 1997, borrowings under these facilities totaled
approximately 2.5 billion pesetas ($16.9 million at the exchange rate on
September 30, 1997), and bore interest at rates ranging from 5.60% to 6.75% per
annum. These facilities are also unsecured.


OTHER INDEBTEDNESS


     At September 30, 1997, the Company had notes payable totaling $14.7
million outstanding, secured by interests in certain of the Company's
equipment. Interest rates on these notes range from 7.50% to 8.50% per annum
and mature in installments through the year 2000.


     In connection with the acquisition of Sintel, the Company currently is
indebted to Telefonica for 3.6 billion pesetas ($24.0 million at the exchange
rate on December 31, 1997), which indebtedness bears interest at 7.87% per
annum. A payment of 1.8 billion pesetas ($12.0 million at the exchange rate on
December 31, 1997) was due on December 31, 1997, with the balance due on
December 31, 1998. The Company has paid a portion of the December 31, 1997
payment, with the remaining amounts to be paid pending resolution of offsetting
amounts between the Company and Telefonica. The Telefonica indebtedness is
unsecured.


                                       45


                              DESCRIPTION OF NOTES


GENERAL


     The New Notes, like the Old Notes, will be issued pursuant to the
Indenture dated February 4, 1998, between the Company and First Trust National
Association, as trustee (the "TRUSTEE"). The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (the "TRUST INDENTURE ACT"). The terms of the
New Notes are substantially identical to the Old Notes in all material respects
(including interest rate and maturity), except that (i) the New Notes will not
be subject to the restrictions on transfer (other than with respect to holders
that are broker-dealers, persons who participated in the distribution of the
Old Notes or affiliates) and (ii) the Registration Rights Agreement covenants
regarding registration and the related Liquidated Damages (other than those
that have accrued and were not paid, if any) with respect to Registration
Defaults will have been deemed satisfied. The Notes are subject to all such
terms, and Holders of Notes are referred to the Indenture and the Trust
Indenture Act for a statement thereof. The following summary of the material
provisions of the Indenture does not purport to be complete and is qualified in
its entirety by reference to the Indenture, including the definitions therein
of certain terms used below. Copies of the proposed form of Indenture and
Registration Rights Agreement will be made available to prospective investors
as set forth under "--Additional Information." The definitions of certain terms
used in the following summary are set forth below under "--Certain
Definitions." For purposes of this "Description of Notes," the term "COMPANY"
refers only to MasTec, Inc. and not to any of its Subsidiaries.


     The Notes will be subordinated in right of payment to all existing and
future Senior Debt of the Company. The Notes will also be effectively
subordinated to all Indebtedness and other liabilities and commitments
(including trade payables and lease obligations) of the Company's Subsidiaries.
As of September 30, 1997, after giving pro forma effect to the Offering and the
application of the net proceeds therefrom, the Notes would have been
subordinated to approximately $72.2 million of Senior Debt of the Company and
indebtedness and other obligations of the Company's subsidiaries. In addition,
the Company would have had $121.5 million of additional borrowings available
under the Credit Facility. The Indenture will permit the Company and its
Restricted Subsidiaries to incur additional indebtedness, including additional
Senior Debt, subject to certain restrictions. See "--Certain
Covenants--Incurrence of Indebtedness and Issuance of Preferred Stock."


     The operations of the Company are conducted through its Subsidiaries and,
therefore, the Company is dependent upon the cash flow of its Subsidiaries to
meet its obligations, including its obligations under the Notes. Any right of
the Company to receive assets of any of its Subsidiaries upon the latter's
liquidation or reorganization (and the consequent right of the Holders of the
Notes to participate in those assets) will be effectively subordinated to the
claims of that Subsidiary's creditors, except to the extent that the Company is
itself recognized as a creditor of such Subsidiary, in which case the claims of
the Company would still be subordinate to any security interest in the assets
of such Subsidiary and any indebtedness of such Subsidiary senior to that held
by the Company. See "Risk Factors--Holding Company Structure."


     As of the date of the Indenture, all of the Company's Subsidiaries were
Restricted Subsidiaries. However, under certain circumstances, the Company will
be able to designate current or future Subsidiaries as Unrestricted
Subsidiaries. Unrestricted Subsidiaries will not be subject to many of the
restrictive covenants set forth in the Indenture.


PRINCIPAL, MATURITY AND INTEREST


     The Notes are limited in aggregate principal amount to $250.0 million, of
which $200.0 million was outstanding as of the date of this Prospectus, and
will mature on February 1, 2008. Interest on the Notes will accrue at the rate
of 7-3/4% per annum and will be payable semi-annually in arrears on February 1
and August 1 of each year, commencing on August 1, 1998, to Holders of record
on the immediately


                                       46


preceding January 15 and July 15. Interest on the Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from the date of original issuance. Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months. Principal of and
premium, interest and Liquidated Damages, if any, on the Notes will be payable
at the office or agency of the Company maintained for such purpose or, at the
option of the Company, payment of interest and Liquidated Damages may be made
by check mailed to the Holders of the Notes at their respective addresses set
forth in the register of Holders of Notes; PROVIDED that all payments of
principal, premium, interest and Liquidated Damages with respect to Notes the
Holders of which have given wire transfer instructions to the Company will be
required to be made by wire transfer of immediately available funds to the
accounts specified by the Holders thereof. Until otherwise designated by the
Company, the Company's office or agency will be the office of the Trustee
maintained for such purpose. The Notes will be issued in denominations of
$1,000 and integral multiples thereof.


SUBORDINATION


     The payment of principal of and premium, interest and Liquidated Damages,
if any, on the New Notes will be subordinated in right of payment, as set forth
in the Indenture, to the prior payment in full of all Senior Debt of the
Company, whether outstanding on the date of the Indenture or thereafter
incurred.


     Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities, the holders of Senior Debt will be entitled to receive
payment in full of all Obligations due in respect of such Senior Debt
(including interest after the commencement of any such proceeding at the rate
specified in the applicable Senior Debt) before the Holders of Notes will be
entitled to receive any payment with respect to the Notes, and until all
Obligations with respect to Senior Debt are paid in full, any distribution to
which the Holders of Notes would be entitled shall be made to the holders of
Senior Debt (except that Holders of Notes may receive Permitted Junior
Securities and payments made from the trust described under "--Legal Defeasance
and Covenant Defeasance").


     The Company also may not make any payment upon or in respect of the Notes
(except in Permitted Junior Securities or from the trust described under
"--Legal Defeasance and Covenant Defeasance") if (i) a default in the payment
of the principal of or premium, or interest on any Designated Senior Debt
occurs and is continuing beyond any applicable period of grace or (ii) any
other default occurs and is continuing with respect to any Designated Senior
Debt that permits holders of the Designated Senior Debt as to which such
default relates to accelerate its maturity and the Trustee receives a notice of
such default (a "PAYMENT BLOCKAGE NOTICE") from the Company or the holders of
such Designated Senior Debt. Payments on the Notes may and shall be resumed (a)
in the case of a payment default, upon the date on which such default is cured
or waived and (b) in case of a nonpayment default, the earlier of the date on
which such nonpayment default is cured or waived or 180 days after the date on
which the applicable Payment Blockage Notice is received, unless the maturity
of any Designated Senior Debt has been accelerated. No new Payment Blockage
Notice may be delivered unless and until 360 days have elapsed since the
effectiveness of the immediately prior Payment Blockage Notice. No nonpayment
default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent
Payment Blockage Notice unless such nonpayment default shall have been cured
for a period of at least 90 days.


     The Indenture further requires that the Company promptly notify holders of
Senior Debt if payment of the Notes is accelerated because of an Event of
Default.


     As a result of the subordination provisions described above, in the event
of a liquidation or insolvency, Holders of Notes may recover less ratably than
creditors of the Company who are holders of Senior Debt.


                                       47


OPTIONAL REDEMPTION


     The Notes will not be redeemable at the Company's option prior to February
1, 2003. Thereafter, the Notes will be subject to redemption at any time at the
option of the Company, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of
principal amount) set forth below, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on February 1 of the years
indicated below:




YEAR                                  PERCENTAGE
- ---------------------------------   -------------
                                 
   2003 .........................       103.875%
   2004 .........................       102.583%
   2005 .........................       101.292%
   2006 and thereafter ..........       100.000%


     Notwithstanding the foregoing, prior to February 1, 2001, the Company may
redeem up to one-third of the aggregate principal amount of Notes at a
redemption price of 107.750% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages, if any, thereon to the redemption date,
with the net cash proceeds of an offering of Equity Interests (other than
Disqualified Stock) of the Company; PROVIDED that (i) at least $133.3 million
in principal amount of the Notes remain outstanding immediately after the
occurrence of such redemption and (ii) such redemption shall occur within 90
days of the date of the consummation of such offering.


SELECTION AND NOTICE


     If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which
the Notes are listed, or, if the Notes are not so listed, on a pro rata basis,
by lot or by such method as the Trustee shall deem fair and appropriate;
PROVIDED that no Notes of $1,000 or less shall be redeemed in part. Notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each Holder of Notes to be redeemed at its
registered address. Notices of redemption may not be conditional. If any Note
is to be redeemed in part only, the notice of redemption that relates to such
Note shall state the portion of the principal amount thereof to be redeemed. A
new Note in principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original
Note. Notes called for redemption become due on the date fixed for redemption.
On and after the redemption date, interest ceases to accrue on Notes or
portions of them called for redemption.


MANDATORY REDEMPTION


     Except as set forth below under "--Repurchase at the Option of Holders,"
the Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes.


REPURCHASE AT THE OPTION OF HOLDERS


     CHANGE OF CONTROL. Upon the occurrence of a Change of Control, the Company
will be obligated to make an offer (a "CHANGE OF CONTROL OFFER") to each Holder
of Notes to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of such Holder's Notes at an offer price in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of purchase (the "CHANGE OF CONTROL
PAYMENT"). Within 30 days following a Change of Control, the Company will mail
a notice to each Holder describing the transaction or transactions that
constitute the Change of Control and offering to repurchase Notes on the date
specified in such notice, which date shall be no earlier than 30 days and no
later than 60 days from the date such notice is mailed (the "CHANGE OF CONTROL
PAYMENT DATE"), pursuant to the procedures required by the Indenture and
described in such notice. The Company will comply with the requirements of Rule
14e-1 under the


                                       48


Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.


     On the Change of Control Payment Date, the Company will, to the extent
lawful, (i)  accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating
the aggregate principal amount of Notes or portions thereof being purchased by
the Company. The Paying Agent will promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; PROVIDED that each such new Note will be in a
principal amount of $1,000 or an integral multiple thereof. The Indenture will
provide that, prior to complying with the provisions of this covenant, but in
any event within 90 days following a Change of Control, the Company will either
repay all outstanding Senior Debt or obtain the requisite consents, if any,
under all agreements governing outstanding Senior Debt to permit the repurchase
of Notes required by this covenant.


     The Change of Control provisions described above will be applicable
whether or not any other provisions of the Indenture are applicable; PROVIDED,
HOWEVER, that the Company shall not be obligated to repurchase the Notes upon a
Change of Control if the Company has irrevocably elected to redeem all of the
Notes under the provisions described under "--Optional Redemption." Except as
described above with respect to a Change of Control, the Indenture does not
contain provisions that permit the Holders of the Notes to require that the
Company repurchase or redeem the Notes in the event of a takeover,
recapitalization or similar transaction.


     The Credit Facility prohibits, and future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may
prohibit, the Company from purchasing any Notes following a Change of Control
and/or provide that certain change of control events with respect to the
Company would constitute a default thereunder. In the event a Change of Control
occurs at a time when the Company is prohibited from purchasing Notes, the
Company could seek the consent of its lenders to the purchase of Notes or could
attempt to refinance the borrowings that contain such prohibition. If the
Company does not obtain such a consent or repay such borrowings, the Company
will remain prohibited from purchasing Notes. The Company's failure to purchase
tendered Notes following a Change of Control would constitute an Event of
Default under the Indenture which would, in turn, constitute a default under
the Credit Facility. In such circumstances, the subordination provisions in the
Indenture would likely restrict payments to the Holders of Notes. See
"--Subordination" and "Description of Certain Indebtedness--Credit Facility."


     The Company will not be required to make a Change of Control Offer
following a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in the Indenture applicable to a Change of Control Offer
made by the Company and purchases all Notes validly tendered and not withdrawn
under such Change of Control Offer.


     ASSET SALES. The Indenture will provide that the Company will not, and
will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale
unless (i) the Company or such Restricted Subsidiary, as the case may be,
receives consideration at the time of such Asset Sale at least equal to the
fair market value (evidenced by a resolution of the Board of Directors set
forth in an Officers' Certificate delivered to the Trustee) of the assets or
Equity Interests issued or sold or otherwise disposed of and (ii) at least 75%
of the consideration therefor received by the Company or such Restricted
Subsidiary is in the form of cash or Cash Equivalents; PROVIDED that the amount
of (a) any liabilities (as shown on the Company's or such Restricted
Subsidiary's most recent balance sheet) of the Company or such Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their
 


                                       49


terms subordinated to the Notes or any guarantee thereof) that are assumed by
the transferee of any such assets and for which the Company or such Restricted
Subsidiary is released from further liability and (b) any securities, notes or
other obligations received by the Company or such Restricted Subsidiary from
such transferee that are promptly converted by the Company or such Restricted
Subsidiary into cash or Cash Equivalents (to the extent of the cash or Cash
Equivalents received) shall be deemed to be cash for purposes of this
provision.


     Within 365 days of the receipt of any Net Proceeds from an Asset Sale, the
Company may apply such Net Proceeds, at its option, (i) to repay Senior Debt of
the Company or Indebtedness of any Restricted Subsidiary (and, in each case, to
correspondingly reduce commitments with respect thereto in the case of
revolving borrowings) or (ii) to the acquisition of a controlling interest in
another business, the making of a capital expenditure or the acquisition of
other long-term assets. Pending the final application of any such Net Proceeds,
the Company may temporarily reduce Senior Debt or otherwise invest such Net
Proceeds in any manner that is not prohibited by the Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of this paragraph will be deemed to constitute "EXCESS
PROCEEDS." When the aggregate amount of Excess Proceeds exceeds $10.0 million,
the Company will be required to make an offer to all Holders of Notes (an
"ASSET SALE OFFER") to purchase the maximum principal amount of Notes that may
be purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date of purchase, in accordance
with the procedures set forth in the Indenture. To the extent that the
aggregate amount of Notes tendered pursuant to an Asset Sale Offer is less than
the Excess Proceeds, the Company may use any remaining Excess Proceeds for
general corporate purposes. If the aggregate principal amount of Notes
surrendered by Holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes to be purchased on a pro rata basis. Upon
completion of an Asset Sale Offer, the amount of Excess Proceeds shall be reset
at zero.


CERTAIN COVENANTS


     RESTRICTED PAYMENTS. The Indenture provides that the Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly:
(i) declare or pay any dividend or make any other payment or distribution on
account of the Company's or any of its Restricted Subsidiaries' Equity
Interests (including, without limitation, any payment in connection with any
merger or consolidation involving the Company or any of its Restricted
Subsidiaries) or to any direct or indirect holders of the Company's or any of
its Restricted Subsidiaries' Equity Interests in their capacity as such (other
than dividends or distributions (a) payable in Equity Interests (other than
Disqualified Stock) of the Company, (b) to the Company or any Wholly Owned
Restricted Subsidiary of the Company, (c) paid by a Restricted Subsidiary of
the Company pro rata to the holders of its Capital Stock or (d) payable in
Equity Interests of Supercanal or Conecel); (ii) purchase, redeem or otherwise
acquire or retire for value (including without limitation, in connection with
any merger or consolidation involving the Company) any Equity Interests of the
Company, any of its Subsidiaries or any direct or indirect parent of the
Company (other than any such Equity Interests owned by the Company or any
Wholly Owned Restricted Subsidiary of the Company); (iii) make any payment on
or with respect to, or purchase, redeem, defease or otherwise acquire or retire
for value any Indebtedness of the Company or any Restricted Subsidiary that is
subordinated to the Notes, except a payment of interest, a payment of principal
at Stated Maturity or a scheduled repayment or scheduled sinking fund payment;
or (iv) make any Restricted Investment (all such payments and other actions set
forth in clauses (i) through (iv) above being collectively referred to as
"RESTRICTED PAYMENTS"), unless, at the time of and after giving effect to such
Restricted Payment:


     (a) no Default or Event of Default shall have occurred and be continuing
   or would occur as a consequence thereof; and


     (b) the Company would, at the time of such Restricted Payment and after
   giving pro forma effect thereto as if such Restricted Payment had been made
   at the beginning of the applicable


                                       50


   four-quarter period, have been permitted to incur at least $1.00 of
   additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
   set forth in the first paragraph of the covenant described below under
   caption "--Incurrence of Indebtedness and Issuance of Preferred Stock;" and
    


     (c) such Restricted Payment, together with the aggregate amount of all
   other Restricted Payments made by the Company and its Restricted
   Subsidiaries after the Closing Date (excluding Restricted Payments
   permitted by clauses (ii) through (vi) of the next succeeding paragraph),
   is less than the sum, without duplication, of (i) 50% of the cumulative
   Consolidated Net Income of the Company for the period (taken as one
   accounting period) from the beginning of the first fiscal quarter
   commencing after the Closing Date to the end of the Company's most recently
   ended fiscal quarter for which internal financial statements are available
   at the time of such Restricted Payment (or, if such Consolidated Net Income
   for such period is a deficit, less 100% of such deficit), plus (ii) 100% of
   the aggregate net cash proceeds received by the Company from the issue or
   sale since the Closing Date of Equity Interests of the Company (other than
   Equity Interests sold to a Subsidiary of the Company and other than
   Disqualified Stock), plus (iii) 50% of any dividends received by the
   Company or a Wholly Owned Restricted Subsidiary after the Closing Date from
   an Unrestricted Subsidiary of the Company, to the extent that such
   dividends were not otherwise included in Consolidated Net Income of the
   Company for such period, plus (iv) $50.0 million, plus (v) the amount by
   which Indebtedness of the Company is reduced on the Company's balance sheet
   upon the conversion or exchange (other than by a Restricted Subsidiary)
   subsequent to the Closing Date of any Indebtedness of the Company
   convertible or exchangeable for Capital Stock (other than Disqualified
   Stock) of the Company (less the amount of any cash or other property
   distributed by the Company upon such conversion or exchange), plus (vi) an
   amount equal to the sum of the net reduction in Investments in Unrestricted
   Subsidiaries resulting from (A) dividends, repayments of the principal of
   loans or advances or other transfers of assets to the Company or any
   Restricted Subsidiary from Unrestricted Subsidiaries or (B) the sale or
   liquidation of any Unrestricted Subsidiaries, plus (vii) to the extent that
   any Unrestricted Subsidiary of the Company is designated to be a Restricted
   Subsidiary, the sum of (A) the lesser of (1) 100% of the Company's
   Investment in such Subsidiary, as shown on the Company's most recent
   balance sheet, and (2) the fair market value of the Company's Investment in
   such Subsidiary, plus (B) 50% of the amount, if any, by which the fair
   market value of the Company's Investment in such Subsidiary exceeds the
   amount determined in the preceding clause (A).


     The foregoing provisions will not prohibit (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at the date of
declaration such payment would have complied with the provisions of the
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness or Equity Interests of the Company
or any Restricted Subsidiary in exchange for, or out of the net cash proceeds
of the substantially concurrent sale (other than to a Subsidiary of the
Company) of, other Equity Interests of the Company (other than any Disqualified
Stock); PROVIDED that the amount of any such net cash proceeds that are
utilized for any such redemption, repurchase, retirement, defeasance or other
acquisition shall be excluded from clause  (c)(ii) of the preceding paragraph;
(iii) the defeasance, redemption, repurchase or other acquisition of
subordinated Indebtedness with the net cash proceeds from an incurrence of
Permitted Refinancing Indebtedness; (iv) the repurchase, redemption or other
acquisition or retirement for value of any Equity Interests of the Company or
any Restricted Subsidiary of the Company held by employees, former employees,
directors or former directors of the Company (or any of its Subsidiaries)
pursuant to any agreement or plan approved by the Company's Board of Directors;
PROVIDED that the aggregate price paid for all such repurchased, redeemed,
acquired or retired Equity Interests shall not exceed $1.0 million in any
twelve-month period and no Default or Event of Default shall have occurred and
be continuing immediately after such transaction; (v) the purchase, repurchase
or acquisition of Capital Stock of the Company, in an amount not to exceed $5.0
million, for distribution, contribution or payment to, or for the benefit of,
any employee benefit plan of the Company or any of its Subsidiaries or any
trust established by the Company or any of its Subsidiaries for the benefit of
its employees; and (vi) any Restricted Payment utilizing cash or other
consideration received by the Company by virtue of


                                       51


its investment in Supercanal or Conecel; PROVIDED that clauses (a) and (b) of
the preceding paragraph are satisfied at the time of such payment.


     The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any non-cash Restricted Payment shall be determined in
good faith by the Board of Directors whose resolution with respect thereto
shall be delivered to the Trustee. Not later than the date of making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant "Restricted
Payments" were computed, which calculations may be based upon the Company's
latest available financial statements.


     The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default. For
purposes of making such determination, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash)
in the Subsidiary so designated will be deemed to be Restricted Payments at the
time of such designation and will reduce the amount available for Restricted
Payments under the first paragraph of this covenant. All such outstanding
Investments will be deemed to constitute Investments in an amount equal to the
fair market value of such Investments at the time of such designation. Such
designation will only be permitted if such Restricted Payment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary.


     Any such designation by the Board of Directors shall be evidenced to the
Trustee by filing with the Trustee a certified copy of the Board Resolution
giving effect to such designation and an Officers' Certificate certifying that
such designation complied with the foregoing conditions. If, at any time, any
Unrestricted Subsidiary would fail to meet the definition of an Unrestricted
Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for
purposes of the Indenture and any Indebtedness of such Subsidiary shall be
deemed to be incurred by a Restricted Subsidiary of the Company as of such date
(and, if such Indebtedness is not permitted to be incurred as of such date
under the covenant described under the caption "--Incurrence of Indebtedness
and Issuance of Preferred Stock," the Company shall be in default of such
covenant). The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Restricted Subsidiary; PROVIDED that such
designation shall be deemed to be an incurrence of Indebtedness by a Restricted
Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted
Subsidiary and such designation shall only be permitted if (i) such
Indebtedness is permitted under the covenant described under the caption
"--Certain Covenants--Incurrence of Indebtedness and Issuance of Preferred
Stock," calculated on a pro forma basis as if such designation had occurred at
the beginning of the four-quarter reference period, and (ii) no Default or
Event of Default would be in existence following such designation.


     INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK. The Indenture
will provide that the Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "INCUR") any
Indebtedness (including Acquired Debt) and that the Company will not permit any
of its Restricted Subsidiaries to issue any shares of preferred stock;
PROVIDED, HOWEVER, that the Company and its foreign Restricted Subsidiaries may
incur Indebtedness (including Acquired Debt) and the Restricted Subsidiaries
may issue preferred stock if the Fixed Charge Coverage Ratio for the Company's
most recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such preferred stock is issued would
have been at least 2.0 to 1, determined on a pro forma basis (including a pro
forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred or the preferred stock had been issued at the
beginning of such four-quarter period.


     The provisions of the first paragraph of this covenant will not apply to
the incurrence of any of the following (collectively, "PERMITTED DEBT"):


                                       52


     (i) the incurrence by the Company or its Restricted Subsidiaries of
Indebtedness under the Credit Facility in an aggregate amount not to exceed
$150.0 million at any one time outstanding, less the aggregate amount of all
Net Proceeds of Asset Sales applied to permanently reduce the amount of such
Indebtedness;


     (ii) the incurrence by the Company of Indebtedness represented by the
Notes and any guarantee of the Notes by any Restricted Subsidiary of the
Company, in each case in an aggregate amount not to exceed $200.0 million;


     (iii) the incurrence by the Company or any of its Restricted Subsidiaries
of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
which are used to refund, refinance or replace Existing Indebtedness or
Indebtedness that was permitted to be incurred by the first paragraph, or by
clause (ii) of the second paragraph of this covenant;


     (iv) the incurrence of Indebtedness between or among the Company and any
of its Restricted Subsidiaries; PROVIDED, HOWEVER, that any subsequent issuance
or transfer of Equity Interests that results in any such Restricted Subsidiary
ceasing to be a Restricted Subsidiary or any subsequent transfer of any such
Indebtedness (except to the Company or a Restricted Subsidiary or a pledge or
other transfer thereof intended to create a security interest therein), and any
sale or other transfer of any such Indebtedness to a Person that is not either
the Company or a Wholly Owned Restricted Subsidiary, shall be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Company or such
Restricted Subsidiary, as the case may be;


     (v) the incurrence by the Company or any of its Restricted Subsidiaries of
Hedging Obligations that are (a) incurred for the purpose of fixing or hedging
interest rate risk with respect to any floating rate Indebtedness that is
permitted by the terms of the Indenture to be outstanding or (b) incurred for
the purpose of fixing or hedging currency exchange rates or prices of
commodities used in the business of the Company and its Restricted
Subsidiaries;


     (vi) the guarantee by the Company or any Restricted Subsidiary of
Indebtedness that was permitted to be incurred by another provision of this
covenant, subject to the covenant described under "Limitation on Guarantees of
Company Indebtedness by Restricted Subsidiaries"; and


     (vii) other Indebtedness of the Company or any Restricted Subsidiary in an
aggregate principal amount at any time outstanding not to exceed $25.0 million.
 


     For purposes of determining compliance with this covenant, in the event
that (a) an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described above or is entitled to be incurred
pursuant to the first paragraph of this covenant, the Company shall, in its
sole discretion, classify such item of Indebtedness in any manner that complies
with this covenant and shall only be required to include such item of
Indebtedness in one of such clauses or pursuant to the first paragraph hereof
and (b) an item of Indebtedness may be divided and classified in more than one
of the types of Indebtedness described above. Accrual of interest, the
accretion of accredit value and the payment of interest in the form of
additional Indebtedness will not be deemed to be an incurrence of Indebtedness
for purposes of this covenant.


     LIENS. The Indenture will provide that the Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien securing Indebtedness or trade
payables on any asset now owned or hereafter acquired, or any income or profits
therefrom or assign or convey any right to receive income therefrom, except
Permitted Liens, unless contemporaneously therewith effective provision is made
to secure the Notes equally and ratably with such Indebtedness or trade
payables for so long as such Indebtedness or trade payables are unsecured by a
Lien.


     DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES. The
Indenture will provide that the Company will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly,


                                       53


create or otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction on the ability of any Restricted Subsidiary to
(i)(a) pay dividends or make any other distributions to the Company or any of
its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any
other interest or participation in, or measured by, its profits, or (b) pay any
Indebtedness owed to the Company or any of its Restricted Subsidiaries, (ii)
make loans or advances to the Company or any of its Restricted Subsidiaries or
(iii) transfer any of its properties or assets to the Company or any of its
Restricted Subsidiaries, except for such encumbrances or restrictions existing
under or by reason of (a) Existing Indebtedness as in effect on the Closing
Date, (b) the Credit Facility as in effect as of the Closing Date, and any
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings thereof, PROVIDED that such
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacement or refinancings are no more restrictive with respect to
such dividend and other payment restrictions than those contained in the Credit
Facility as in effect on the Closing Date, (c) the Indenture and the Notes, (d)
applicable law, (e) any instrument governing Indebtedness or Capital Stock of a
Person acquired by the Company or any of its Restricted Subsidiaries as in
effect at the time of such acquisition (except to the extent such Indebtedness
was incurred in connection with or in contemplation of such acquisition), (f)
by reason of customary non-assignment provisions or other restrictions in
leases, licenses and other contracts entered into in the ordinary course of
business, (g) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in clause
(iii) above on the property so acquired, (h) Permitted Refinancing
Indebtedness, PROVIDED that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are no more restrictive than
those contained in the agreements governing the Indebtedness being refinanced,
(i) in the case of clause (iii) above, any encumbrance or restriction (A) by
virtue of any transfer of, agreement to transfer, option or right with respect
to, or Lien on, any property or assets of the Company or any Restricted
Subsidiary not otherwise prohibited by the Indenture or (B) contained in
security agreements, mortgages or Capitalized Lease Obligations securing
Indebtedness of a Restricted Subsidiary to the extent such encumbrance or
restrictions restrict the transfer of the property subject to such security
agreements, mortgages or Capitalized Lease Obligations; (j) any restriction
with respect to a Restricted Subsidiary imposed pursuant to an agreement
entered into for the sale or disposition of Capital Stock or assets of such
Restricted Subsidiary pending the closing of such sale or disposition; and (k)
customary net worth provisions contained in leases and other agreements entered
into by a Restricted Subsidiary in the ordinary course of business.


     MERGER, CONSOLIDATION, OR SALE OF ASSETS. The Indenture will provide that
the Company may not consolidate or merge with or into, or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
consolidated properties or assets in one or more related transactions, to
another corporation, Person or entity unless (i) the Company is the surviving
corporation or the entity or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made is a corporation organized or existing under the laws of the United
States, any state thereof or the District of Columbia; (ii) the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company) or the entity or Person to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made assumes all the
obligations of the Company, under the Notes and the Indenture pursuant to a
supplemental indenture in a form reasonably satisfactory to the Trustee; (iii)
immediately after such transaction no Default or Event of Default exists; and
(iv) except in the case of a merger of the Company with or into a Wholly Owned
Restricted Subsidiary, or the merger of a Wholly Owned Restricted Subsidiary
with or into the Company, the Company or the Person formed by or surviving any
such consolidation or merger, or to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made (a) will have
Consolidated Net Worth immediately after the transaction equal to or greater
than the Consolidated Net Worth of the Company, immediately preceding the
transaction and (b) will, at the time of such transaction and after giving pro
forma effect thereto as if such transaction had occurred at the beginning of
the applicable four-quarter period, be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Fixed Charge


                                       54


Coverage Ratio test set forth in the first paragraph of the covenant described
above under the caption "--Incurrence of Indebtedness and Issuance of Preferred
Stock."


     LIMITATION ON GUARANTEES OF COMPANY INDEBTEDNESS BY RESTRICTED
SUBSIDIARIES. The Company will not permit any Restricted Subsidiary, directly
or indirectly, to guarantee any Indebtedness of the Company other than the
Notes (the "Other Company Indebtedness"), unless such Restricted Subsidiary
contemporaneously executes and delivers a supplemental indenture to the
Indenture providing for a Guarantee of payment of the Notes by such Restricted
Subsidiary to the same extent as the guarantee (the "Other Company Indebtedness
Guarantee") of the Other Company Indebtedness (including waiver of subrogation,
if any). The Guarantee of a Restricted Subsidiary will be subordinated in right
of payment to all existing and future Senior Debt of such Restricted Subsidiary
to the same extent as the Notes are subordinated to Senior Debt of the Company.
See "--Subordination."


     Each Guarantee of the Notes created by a Restricted Subsidiary pursuant to
the provisions described in the foregoing paragraph shall be in form and
substance satisfactory to the Trustee and shall provide, among other things,
that it shall be automatically and unconditionally released and discharged upon
(i) any sale, exchange or transfer permitted by the Indenture of (a) all of the
Company's Capital Stock in such Restricted Subsidiary, or (b) the sale of all
or substantially all of the assets of the Restricted Subsidiary and upon the
application of the Net Proceeds from such sale in accordance with the
requirements of the "Asset Sales" provisions described herein; or (ii) the
release or discharge of the Other Company Indebtedness Guarantee that resulted
in the creation of such guarantee of the Notes, except a discharge or release
by or as a result of payment under such Other Company Indebtedness Guarantee.


     TRANSACTIONS WITH AFFILIATES. The Indenture will provide that the Company
will not, and will not permit any of its Restricted Subsidiaries to, make any
payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate (each of the
foregoing, an "AFFILIATE TRANSACTION"), unless (i) such Affiliate Transaction
is on terms that are no less favorable to the Company or such Restricted
Subsidiary than those that would have been obtained in a comparable transaction
by the Company or such Restricted Subsidiary with an unrelated Person and (ii)
the Company delivers to the Trustee (a) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $5 million, a resolution of the Board of Directors
set forth in an Officers' Certificate certifying that such Affiliate
Transaction complies with clause (i) above and that such Affiliate Transaction
has been approved by a majority of the disinterested members of the Board of
Directors and (b) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate consideration in excess of
$15 million, an opinion as to the fairness to the Holders of such Affiliate
Transaction from a financial point of view issued by an accounting, appraisal
or investment banking firm of national standing.


     The foregoing provisions will not prohibit: (i) transactions between or
among the Company and/or its Restricted Subsidiaries; (ii) any Restricted
Payment that is permitted by the provisions of the Indenture described above
under the caption "--Restricted Payments"; (iii) any issuance of securities or
other payments, awards or grants in cash, securities or otherwise pursuant to,
or the funding of, employment arrangements, stock options and stock ownership
plans approved by the Board of Directors of the Company; (iv) any fees,
indemnities, loans or advances to employees in the ordinary course of business;
(v) any payment approved by the Board of Directors in connection with the
registration for sale or distribution by any Affiliate of the Company of any
Equity Interests of the Company, including reimbursements for offering
expenses, underwriting discounts and commissions; (vi) payments made to the
Federal Trade Commission or other foreign or domestic governmental agency on
behalf of any Affiliate by virtue of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, or other similar federal, state or
foreign laws in connection with the acquisition by such Affiliate of additional
Equity Interests in the Company or the acquisition by the Company or any
Restricted Subsidiary of the Capital Stock or assets of another Person or the
merger by the Company or


                                       55


any Restricted Subsidiary with another Person; and (vii) any Affiliate
Transaction with Conecel or Supercanal not involving the payment of
consideration by the Company or any Restricted Subsidiary.


     LIMITATION ON OTHER SENIOR SUBORDINATED DEBT. The Indenture will provide
that the Company will not incur any Indebtedness that is subordinate or junior
in right of payment to any Senior Debt of the Company and senior in any respect
in right of payment to the Notes.


     PAYMENTS FOR CONSENT. The Indenture provides that neither the Company nor
any of its Restricted Subsidiaries will, directly or indirectly, pay or cause
to be paid any consideration, whether by way of interest, fee or otherwise, to
any Holder of any Notes for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of the Indenture or the Notes
unless such consideration is offered to be paid or is paid to all Holders of
the Notes that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or agreement.


     REPORTS. The Indenture provides that, whether or not required by the rules
and regulations of the Commission, so long as any Notes are outstanding, the
Company will furnish to the Holders of Notes (i)  all quarterly and annual
financial information that would be required to be contained in a filing with
the Commission on Forms 10-Q and 10-K if the Company were required to file such
Forms, including a "Management's Discussion and Analysis of Financial Condition
and Results of Operations" that describes the financial condition and results
of operations of the Company and its consolidated Subsidiaries and, with
respect to the annual information only, a report thereon by the Company's
certified independent accountants and (ii) all current reports that would be
required to be filed with the Commission on Form 8-K if the Company were
required to file such reports. To the extent there is a material difference
between the consolidated financial condition and results of operations of (i)
the Company and (ii) the Company and its Restricted Subsidiaries separate from
the financial condition and results of operations of the Unrestricted
Subsidiaries of the Company, the Company shall also include, either on the face
of the financial statements or in a footnote thereto, the Consolidated Cash
Flow and Fixed Charge Coverage Ratio of the Company and its Restricted
Subsidiaries. In addition, whether or not required by the rules and regulations
of the Commission, the Company will file a copy of all such information and
reports with the Commission for public availability (unless the Commission will
not accept such a filing) and make such information available to securities
analysts and prospective investors upon request. In addition, the Company and
its Restricted Subsidiaries will agree that, for so long as any Notes remain
outstanding, they will furnish to the Holders and to securities analysts and
prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act.


EVENTS OF DEFAULT AND REMEDIES


     The Indenture provides that each of the following constitutes an Event of
Default: (i) default for 30 days in the payment when due of interest on, or
Liquidated Damages, if any, with respect to, the Notes (whether or not
prohibited by the subordination provisions of the Indenture); (ii) default in
payment when due of the principal of or premium, if any, on the Notes (whether
or not prohibited by the subordination provisions of the Indenture); (iii)
failure by the Company to comply with the provisions described under the
caption "--Merger, Consolidation or Sale of Assets;" (iv) failure by the
Company for 30 days after written notice by the Trustee or the Holders of at

of its obligations in the covenants described above under the captions
"--Change of Control," "--Asset Sales," "--Restricted Payments," or
"--Incurrence of Indebtedness and Issuance of Preferred Stock"; (v) the failure
by the Company for 60 days after written notice by the Trustee or the Holders
of at least 25% in principal amount of the then outstanding Notes the Company
with any of its other agreements in the Indenture or the Notes; (vi) default
under any mortgage, indenture or instrument under which there may be issued or
by which there may be secured or evidenced any Indebtedness for money borrowed
by the Company or any of its Significant Subsidiaries (or the payment of which
is guaranteed by the Company or any of its Significant Subsidiaries), whether
such Indebtedness or guarantee now exists or is created after the Closing Date,
which default (a) is caused by a failure to pay principal of or premium, if
any, or interest on such


                                       56


Indebtedness prior to the expiration of the grace period provided in such
Indebtedness on the date of such default (a "PAYMENT DEFAULT") or (b) results
in the acceleration of such Indebtedness prior to its express maturity and, in
each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$15.0 million or more; (vii) failure by the Company or any of its Restricted
Subsidiaries to pay final judgments aggregating in excess of $15.0 million and
either (a) any creditor commences enforcement proceedings upon any such
judgment or (b) such judgments are not paid, discharged or stayed for a period
of 60 days; (viii) except as permitted by the Indenture, any Guarantee of the
Notes by any Restricted Subsidiary which is a Significant Subsidiary shall be
held in any judicial proceeding to be unenforceable or invalid or shall cease
for any reason to be in full force and effect, or any Restricted Subsidiary
which is a Significant Subsidiary, or any Person acting on behalf of any
Restricted Subsidiary which is a Significant Subsidiary, shall deny or
disaffirm its obligations under any Guarantee of the Notes; and (ix) certain
events of bankruptcy or insolvency with respect to the Company or any of its
Restricted Subsidiaries.


     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, with respect to the Company, any Significant
Subsidiary or any group of Restricted Subsidiaries that, taken together, would
constitute a Significant Subsidiary, all outstanding Notes will become due and
payable without further action or notice. Holders of the Notes may not enforce
the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of the Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest.


     In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have
had to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to
February 1, 2003 by reason of any willful action (or inaction) taken (or not
taken) by or on behalf of the Company with the intention of avoiding the
prohibition on redemption of the Notes prior to such date, then the premium
specified in the Indenture shall also become immediately due and payable to the
extent permitted by law upon the acceleration of the Notes.


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


     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required within 30
days after becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.


NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES, INCORPORATORS AND
STOCKHOLDERS


     No director, officer, employee, incorporator or stockholder of the Company
or any Restricted Subsidiary (other than the Company and its Restricted
Subsidiaries), as such, shall have any liability for any obligations of the
Company or such Restricted Subsidiary under the Notes, the Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of Notes by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of
the Notes. Such waiver may not be effective to waive liabilities under the
federal securities laws and it is the view of the Commission that such a waiver
is against public policy.


                                       57


LEGAL DEFEASANCE AND COVENANT DEFEASANCE


     The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("LEGAL
DEFEASANCE") except for (i) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of and premium, interest and
Liquidated Damages, if any, on the Notes when such payments are due from the
trust referred to below, (ii) the Company's obligations with respect to the
Notes concerning issuing temporary Notes, registration of Notes, mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for
payment and money for security payments held in trust, (iii) the rights,
powers, trusts, duties and immunities of the Trustee, and the Company's
obligations in connection therewith and (iv) the Legal Defeasance provisions of
the Indenture. In addition, the Company may, at its option and at any time,
elect to have the obligations of the Company released with respect to certain
covenants that are described in the Indenture ("COVENANT DEFEASANCE") and
thereafter any omission to comply with such obligations shall not constitute a
Default or Event of Default with respect to the Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, rehabilitation and insolvency events) described under "Events of
Default" will no longer constitute an Event of Default with respect to the
Notes.


     In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the
benefit of the Holders of the Notes, cash in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent
public accountants, to pay the principal of and premium, interest and
Liquidated Damages, if any, on the outstanding Notes on the stated maturity or
on the applicable redemption date, as the case may be, and the Company must
specify whether the Notes are being defeased to maturity or to a particular
redemption date; (ii) in the case of Legal Defeasance, the Company shall have
delivered to the Trustee an opinion of counsel in the United States reasonably
acceptable to the Trustee confirming that (a) the Company has received from, or
there has been published by, the Internal Revenue Service a ruling or (b) since
the Closing Date, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such opinion of
counsel shall confirm that, the Holders of the outstanding Notes will not
recognize income, gain or loss for federal income tax purposes as a result of
such Legal Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case
if such Legal Defeasance had not occurred; (iii) in the case of Covenant
Defeasance, the Company shall have delivered to the Trustee an opinion of
counsel in the United States reasonably acceptable to the Trustee confirming
that the Holders of the outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such Covenant Defeasance
and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred; (iv) no Default or Event of Default shall have
occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such
deposit) or insofar as Events of Default from bankruptcy or insolvency events
are concerned, at any time in the period ending on the 91st day after the date
of deposit; (v) such Legal Defeasance or Covenant Defeasance will not result in
a breach or violation of, or constitute a default under any material agreement
or instrument (other than the Indenture) to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound; (vi) the Company shall have delivered to the Trustee an opinion of
counsel to the effect that after the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally; (vii) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders of Notes over the other creditors of the
Company with the intent of defeating, hindering, delaying or defrauding
creditors of the Company or others; and (viii) the Company shall have delivered
to the Trustee an Officers' Certificate and an opinion of counsel, each stating
that all conditions precedent provided for or relating to the Legal Defeasance
or the Covenant Defeasance have been complied with.


                                       58


TRANSFER AND EXCHANGE


     A Holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company is not required to transfer or exchange any Note
selected for redemption. Also, the Company is not required to transfer or
exchange any Note for a period of 15 days before a selection of Notes to be
redeemed.


     The registered Holder of a Note will be treated as the owner of it for all
purposes.


AMENDMENT, SUPPLEMENT AND WAIVER


     Except as provided in the next two succeeding paragraphs, the Indenture
and the Notes may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount of the Notes then outstanding
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes), and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including consents obtained in connection with a tender
offer or exchange offer for Notes).


     Without the consent of each Holder affected, an amendment or waiver may
not (with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver, (ii) reduce the principal of or change the fixed maturity
of any Note or alter the provisions with respect to the redemption of the Notes
(other than provisions relating to the covenants described above under the
caption "--Repurchase at the Option of Holders"), (iii) reduce the rate of or
change the time for payment of interest on any Note, (iv) waive a Default or
Event of Default in the payment of principal of or premium, interest or
Liquidated Damages, if any, on the Notes (except a rescission of acceleration
of the Notes by the Holders of at least a majority in aggregate principal
amount of the Notes and a waiver of the payment default that resulted from such
acceleration), (v) make any Note payable in money other than that stated in the
Notes, (vi) make any change in the provisions of the Indenture relating to
waivers of past Defaults or the rights of Holders of Notes to receive payments
of principal of or premium, interest or Liquidated Damages, if any, on the
Notes, (vii) waive a redemption payment with respect to any Note (other than a
payment required by one of the covenants described above under the caption
"--Repurchase at the Option of Holders"), or (viii) make any change in the
foregoing amendment and waiver provisions. In addition, any amendment to the
provisions of Article 10 of the Indenture (which relate to subordination) will
require the consent of all holders of Senior Debt, and the consent of the
Holders of at least 75% in aggregate principal amount of the Notes then
outstanding if such amendment would adversely affect the rights of Holders of
Notes.


     Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the Trustee may amend or supplement the Indenture or the Notes
to cure any ambiguity, defect or inconsistency, to provide for uncertificated
Notes in addition to or in place of certificated Notes, to provide for the
assumption of the Company's obligations to Holders of Notes in the case of a
merger or consolidation, to make any change that would provide any additional
rights or benefits to the Holders of Notes or that does not adversely affect
the legal rights under the Indenture of any such Holder, or to comply with
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the Trust Indenture Act.


CONCERNING THE TRUSTEE


     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
such claim as security or otherwise. The Trustee will be permitted to engage in
other


                                       59


transactions; however, if it acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue or resign.


     The Holders of a majority in principal amount of the then outstanding
Notes will have the right to direct the time, method and place of conducting
any proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any Holder of Notes, unless such Holder shall have offered to
the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.


ADDITIONAL INFORMATION


     Anyone who receives this Offering Circular may obtain a copy of the
Indenture and Registration Rights Agreement without charge by writing to
MasTec, Inc., 3155 N.W. 77th Avenue, Miami, Florida 33122, Attention: Corporate
Secretary.


BOOK-ENTRY, DELIVERY AND FORM


     The Notes were initially offered and sold (i) to "qualified institutional
buyers" (as defined in Rule 144A under the Securities Act) in reliance on the
exemption from the registration requirements of the Securities Act provided by
Rule 144A, (ii) to other institutional "accredited investors" (as defined in
rule 501(a)(1), (2), (3) or (7) under the Securities Act) that executed and
delivered a letter containing certain representations and agreements and (iii)
outside the United States in reliance on Regulation S under the Securities Act.
Except as set forth below, the New Notes will initially be issued in the form
of one or more registered Notes in global form without interest coupons (each a
"Global Note"). Each Global Note will be deposited with, or on behalf of, the
Depositary and will be registered in the name of Cede & Co., as nominee of the
Depositary (such nominee being referred to herein as the "GLOBAL NOTE HOLDER"),
in each case for credit to an account of a direct or indirect participant as
described below.


     New Notes that are issued as described below under "--Certificated
Securities" will be issued in the form of registered definitive certificates
(the "CERTIFICATED SECURITIES"). Such Certificated Securities may, unless the
Global Notes have previously been exchanged for Certificated Securities, be
exchanged for an interest in a Global Note representing the principal amount of
Notes being transferred.


     The Depositary has advised the Company that it is a limited-purpose trust
company that was created to hold securities for its participating organizations
(collectively, the "PARTICIPANTS" or the "DEPOSITARY'S PARTICIPANTS") and to
facilitate the clearance and settlement of transactions in such securities
between Participants through electronic book-entry changes in accounts of its
Participants. The Depositary's Participants include securities brokers and
dealers (including the Initial Purchasers), banks and trust companies, clearing
corporations and certain other organizations. Access to the Depositary's system
is also available to other entities such as banks, brokers, dealers and trust
companies (collectively, the "INDIRECT PARTICIPANTS" or the "DEPOSITARY'S
INDIRECT PARTICIPANTS") that clear through or maintain a custodial relationship
with a Participant, either directly or indirectly. Persons who are not
Participants may beneficially own securities held by or on behalf of the
Depositary only thorough the Depositary's Participants or the Depositary's
Indirect Participants.


     The Company expects that, pursuant to procedures established by the
Depositary, (i) upon deposit of the Global Notes, the Depositary will credit
the accounts of Participants designated by the Exchange Agent with portions of
the principal amount of the Global Notes and (ii) ownership of the Notes
evidenced by the Global Notes will be shown on, and the transfer of ownership
thereof will be effected only through, records maintained by the Depositary
(with respect to the interests of the Depositary's Participants), the
Depositary's Participants and the Depositary's Indirect Participants.
Prospective


                                       60


purchasers are advised that the laws of some states require that certain
persons take physical delivery in definitive form of securities that they own.
Consequently, the ability to transfer Notes evidenced by the Global Notes will
be limited to such extent. For certain other restrictions on the
transferability of the Notes, see "Notice to Investors."

     Beneficial interests in the one Global Note may be transferred to a person
who takes delivery in the form of a beneficial interest in another Global Note
only upon receipt by the Trustee of a written certification (in the form
provided in the Indenture) to the effect that such transfer is being made in
accordance with the Indenture and with the Securities Act and any applicable
securities laws of any state of the United States or any other jurisdiction.
Any beneficial interest in one of the Global Notes that is transferred to a
person who takes delivery in the form of a beneficial interest in another
Global Note will, upon transfer, cease to be a beneficial interest in such
Global Note and become a beneficial interest in the other Global Note and
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Note for as long as it remains such a beneficial interest.

     So long as the Global Note Holder is the registered owner of any Notes,
the Global Note Holder will be considered the sole Holder under the Indenture
of any Notes evidenced by the Global Notes. Beneficial owners of Notes
evidenced by the Global Notes will not be considered the owners or Holders
thereof under the Indenture for any purpose, including with respect to the
giving of any directions, instructions or approvals to the Trustee thereunder.
Neither the Company nor the Trustee will have any responsibility or liability
for any aspect of the records of the Depositary or for maintaining, supervising
or reviewing any records of the Depositary relating to the Notes.

     Payments in respect of the principal of and premium, interest and
Liquidated Damages, if any, on any Notes registered in the name of the Global
Note Holder on the applicable record date will be payable by the Trustee to or
at the direction of the Global Note Holder in its capacity as the registered
Holder under the Indenture. Under the terms of the Indenture, the Company and
the Trustee may treat the persons in whose names Notes, including the Global
Notes, are registered as the owners thereof for the purpose of receiving such
payments. Consequently, neither the Company nor the Trustee has or will have
any responsibility or liability for the payment of such amounts to beneficial
owners of Notes. The Company believes, however, that it is currently the policy
of the Depositary to immediately credit the accounts of the relevant
Participants with such payments, in amounts proportionate to their respective
holdings of beneficial interests in the relevant security as shown on the
records of the Depositary. Payments by the Depositary's Participants and the
Depositary's Indirect Participants to the beneficial owners of Notes will be
governed by standing instructions and customary practice and will be the
responsibility of the Depositary's Participants or the Depositary's Indirect
Participants.

     CERTIFICATED SECURITIES. Subject to certain conditions, any person having
a beneficial interest in a Global Note may, upon request to the Trustee,
exchange such beneficial interest for Notes in the form of Certificated
Securities. Upon any such issuance, the Trustee is required to register such
Certificated Securities in the name of, and cause the same to be delivered to,
such person or persons (or the nominee of any thereof). All such certificated
Notes will bear any applicable restrictive legends. In addition, if (i) the
Company notifies the Trustee in writing that the Depositary is no longer
willing or able to act as a depositary and the Company is unable to locate a
qualified successor within 90 days or (ii) the Company, at its option, notifies
the Trustee in writing that it elects to cause the issuance of Notes in the
form of Certificated Securities under the Indenture, then, upon surrender by
the Global Note Holder of the Global Notes, Notes in such form will be issued
to each person that the Global Note Holder and the Depositary identify as being
the beneficial owner of the related Notes.

     Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.

     SAME-DAY SETTLEMENT AND PAYMENT. The Indenture will require that payments
in respect of the Notes represented by the Global Notes (including principal,
premium, interest and Liquidated


                                       61


Damages, if any) be made by wire transfer of immediately available funds to the
accounts specified by the Global Note Holder. With respect to Certificated
Securities, the Company will make all payments of principal, premium, interest
and Liquidated Damages, if any, by wire transfer of immediately available funds
to the accounts specified by the Holders thereof or, if no such account is
specified, by mailing a check to each such Holder's registered address.


     The Notes represented by the Global Notes are expected to trade in the
Depositary's Same-Day Funds Settlement System, and any permitted secondary
market trading activity in such Notes will, therefore, be required by the
Depositary to be settled in immediately available funds. The Company expects
that secondary trading in the Certificated Securities will also be settled in
immediately available funds.


CERTAIN DEFINITIONS


     Set forth below are certain defined terms used in the Indenture. Reference

the Exchange Act) other than the Principals or any Wholly Owned Restricted
Subsidiary of the Company; (ii) the adoption of a plan relating to the
liquidation or dissolution of the Company; (iii) the consummation of any

     "CLOSING DATE" means February 4, 1998.


     "CONSOLIDATED CASH FLOW" means, with respect to any Person for any period,

Obligations), and (iv) depreciation and amortization (including amortization of
goodwill and other intangibles but excluding amortization of prepaid cash
expenses that were paid in a prior period) in each case, on a consolidated
basis and determined in accordance with GAAP. Notwithstanding the foregoing,
the provision for taxes based on the income or profits of, and the depreciation
and amortization of, a Restricted Subsidiary of a Person shall be added to
Consolidated Net Income to compute Consolidated Cash Flow only to the extent
(and in the same proportion) that the Net Income of such Restricted Subsidiary
was included in calculating the


                                       63


Consolidated Net Income of such Person and only if a corresponding amount would
be permitted at the date of determination to be dividended to the Company by
such Restricted Subsidiary without prior approval (that has not been obtained)

judgments, decrees, orders, statutes, rules and governmental regulations
applicable to such Restricted Subsidiary or its stockholders.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS


     The following is a discussion of certain United States federal income and
estate tax consequences to U.S. Holders and Non-U.S. Holders of owning and
disposing of the Notes. Hereinafter, the terms "U.S. Holder" and "Non-U.S.
Holder" refer, respectively, to holders of Notes that are or are not classified
as United States persons for United States federal income and estate tax
purposes.


     This discussion does not deal with all aspects of United States federal
income and estate taxation that may be relevant to holders of Notes and does
not deal with tax consequences arising under the laws of any foreign, state or
local jurisdiction. It is, moreover, based upon the provisions of existing law
on the date hereof, including, in particular, the Internal Revenue Code of
1986, as amended (the "Code"), Treasury regulations promulgated thereunder and
other administrative and judicial interpretations thereof, all of which are
subject to change at any time, with or without retroactive effect. Provisions
of existing law are also unclear in certain respects. This discussion does not
address the tax consequences to subsequent purchasers of Notes and is limited
to purchasers who hold the Notes as capital assets, within the meaning of
section 1221 of the Code. This discussion also does not address the tax
consequences to Non-U.S. Holders that are subject to United States federal
income tax on a net basis on income realized with respect to a Note because
such income is effectively connected with the conduct of a United States trade
or business. Such Non-U.S. Holders are generally taxed in a similar manner to
U.S. Holders, but certain special rules do apply. Moreover, this discussion is
for general information only and does not address all of the tax consequences
that may be relevant to particular initial purchasers in light of their
personal circumstances or to certain types of initial purchasers (such as
certain financial institutions, insurance companies, tax-exempt entities,
dealers in securities or persons who have hedged the risk of owning a Note).


     PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO
THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE NOTES, INCLUDING THE APPLICABILITY OF ANY FEDERAL TAX LAWS
OR ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND ANY CHANGES (OR PROPOSED CHANGES)
IN APPLICABLE TAX LAWS OR INTERPRETATIONS THEREOF.


U.S. HOLDERS


     INTEREST ON NOTES. Interest on a Note will be taxable to a U.S. Holder as
ordinary interest income in accordance with the U.S Holder's method of tax
accounting at the time that such interest is accrued or (actually or
constructively) received.


     DISPOSITION OF NOTES. In general, a U.S. Holder of a Note will recognize
gain or loss upon the sale, redemption, retirement or other disposition of the
Note measured by the difference between the amount of cash and fair market
value of other property received (except to the extent attributable to the
payment of accrued interest) and the U.S. Holder's adjusted tax basis in the
Note. A U.S. Holder's adjusted tax basis in a Note generally will equal the
cost of the Note to the U.S. Holder, less any principal payments received by
such U.S. Holder with respect to the Note. Any portion of the amount realized
on the sale or other disposition of a Note that represents accrued but unpaid
interest will be treated as a payment of such interest. The gain or loss on
such disposition of Notes will be a long-term capital gain or loss taxed at
lower rates than items of ordinary income if Notes have been held as capital
assets for more than one year but not more than 18 months (28%) or 18 months

the Notes have been held for not more than 12 months.

NON-U.S. HOLDERS


     PAYMENT OF INTEREST. A Non-U.S. Holder will not be subject to United
States federal income tax by withholding or otherwise on the accrual (or
payment) of interest on a Note (provided that the beneficial owner of the Note
fulfills the statement requirements set forth in applicable Treasury
Regulations on Form W-8 or a substitute Form W-8 (or a successor form)) unless
(A) such Non-U.S. Holder actually or constructively owns 10% or more of the
total combined voting power of all classes of stock of the Company entitled to
vote, or (B) such interest is effectively connected with the conduct of a trade
or business by the Non-U.S. Holder in the United States. A Non-U.S. Holder that
is not exempt from tax under such rules will be subject to United States
federal income tax withholding (provided Form 4224 is properly provided) at a
rate of 30% unless the interest is effectively connected with the conduct of a
United States trade or business.


     GAIN ON DISPOSITION OF NOTES. A Non-U.S. Holder will not be subject to
United States federal income tax by withholding or otherwise on gain realized
on the disposition of a Note unless (i) in the case of a Non-U.S. Holder who is
an individual, such Non-U.S. Holder is present in the United States for a
period or periods aggregating 183 days or more during the taxable year of the
disposition (in which case such individual may be taxed as a U.S. Holder) and
certain other conditions are met, or (ii) the gain is effectively connected
with the conduct of a trade or business by the Non-U.S. Holder in the United
States.


     EFFECTIVELY CONNECTED INCOME. To the extent that interest income or gain
on the disposition of Notes is effectively connected with the conduct of a
trade or business of the Non-U.S. Holder in the United States, such income will
be subject to United States federal income tax at the same rates generally
applicable to United States persons. Additionally, in the case of a non-U.S.
Holder which is a corporation, such effectively connected income may be subject
to the United States branch profits tax at the rate of 30% (or lower treaty
rates).


     ESTATE TAX. Notes held at the time of death by an individual Non-U.S.
Holder will not be subject to United States federal estate tax, provided that
at such time, (i) such holder did not actually or constructively own 10% or
more of the total combined voting power of all classes of stock of the Company
entitled to vote, and (ii) the Notes were not held in connection with such
holder's trade or business in the United States.


     TREATIES. Applicable treaties between the United States and a country in
which a Non-U.S. Holder is a resident may alter the tax consequences described
above.


     NEW FINAL WITHHOLDING REGULATIONS. The Treasury Department recently
promulgated final regulations regarding the withholding rules described above
and backup withholding and information reporting rules described below that are
applicable to Non-U.S. Holders ("New Final Withholding Regulations"). In
general, the New Final Withholding Regulations do not significantly alter the
substantive withholding and information reporting requirements but rather unify
current certification procedures and forms and clarify reliance standards. The
New Final Withholding Regulations are generally effective for payments made
after December 31, 1998, subject to certain transition rules.


INFORMATION REPORTING AND BACKUP WITHHOLDING


     In addition to the withholding rules described above, interest and
payments of proceeds from the disposition by certain non-corporate holders of
the Notes may be subject to backup withholding at a rate of 31%. Such a U.S.
Holder generally will be subject to backup withholding at a rate of 31% unless
the recipient of such payment supplies an accurate taxpayer identification
number, as well as certain other information, or otherwise establishes, in the
manner prescribed by law, an exemption from backup withholding. Any amount
withheld under backup withholding is allowable as a credit against the U.S.
Holder's federal income tax, upon furnishing the required information.


                                       72


     Generally, backup withholding of United States federal income tax at a
rate of 31% and information reporting may apply to payments of principal,
interest and premium (if any) to Non-U.S. Holders that are not "Exempt
Recipients" and that fail to provide certain information as may be required by
United States law and applicable regulations. Under currently effective United
States Treasury regulations, the payment of the proceeds of the disposition of
the Notes to or through the United States office of a broker will be subject to
information reporting and backup withholding at a rate of 31% unless the owner
certifies its status as a Non-U.S. Holder under penalties of perjury or
otherwise establishes an exemption. The proceeds of the disposition by a
Non-U.S. Holder of the Notes to or through a foreign office of a broker
generally will not be subject to backup withholding. However, if such broker is
a U.S. person, a controlled foreign corporation for United States tax purposes,
or a foreign person 50% or more of whose gross income from all sources for a
specified three-year period is from activities that are effectively connected
with a United States trade or business, information reporting will apply unless
such broker has documentary evidence (other than merely a foreign address) in
its files of the owner's status as a Non-U.S. Holder and has no actual
knowledge to the contrary. Both backup withholding and information reporting
will apply to the proceeds from such dispositions if the broker has actual
knowledge that the payee is a U.S. Holder.


     Holders should consult their tax advisors regarding the application of
withholding tax, information reporting and backup withholding in their
particular situation and the availability of an exemption therefrom, and the
procedures for obtaining any such exemption including the impact of the New
Final Withholding Regulations.


LIQUIDATED DAMAGES


     As more fully described under "Description of Notes--Registration Rights;
Liquidated Damages," the Company may be required to pay Liquidated Damages to
U.S. Holders of the Notes. Although the matter is not free from doubt, the
Company intends to take the position that a U.S. Holder of a Note should be
required to report any Liquidated Damages as ordinary income for United States
federal income tax purposes only at the time it accrues or is received in
accordance with such holder's method of accounting. It is possible, however,
that the Internal Revenue Service may take a different position, in which case
the timing and amount of income may be different.


EXCHANGE OFFER


     The exchange of Old Notes for New Notes pursuant to the Exchange Offer
will have no United States federal income tax consequences to U.S. Holders of
Old Notes and the holding period of the New Notes will include the holding
period of the Old Notes and the basis of the New Notes will be the same as the
basis of the Old Notes immediately before the exchange.


                                       73


                             PLAN OF DISTRIBUTION


     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of the New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes
acquired as a result of market-making activities or other trading activities.
The Company has agreed that it will make this prospectus available to any
broker-dealer for use in connection with any such resale for a period of 180
days after the Expiration Date or until all participating broker-dealers have
so resold.


     The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchasers or to or through brokers or dealers who may
receive compensation in the form of commissions or concession from any such
broker-dealer and/or the purchasers of any New Notes. Any broker-dealer that
resells New Notes that were received by it for its own account pursuant to the
Exchange Offer and any broker-dealer that participates in a distribution of New
Notes may be deemed to be an "underwriter" within the meaning of the Securities
Act, and any profit on any resale of New Notes and any commissions or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.


     The Company has not entered into any arrangement or understanding with any
person to distribute the New Notes to be received in the Exchange Offer, and to
the best of the Company's information and belief, each person participating in
the Exchange Offer is acquiring the New Notes in its ordinary course of
business and has no arrangement or understanding with any person to participate
in the distribution of the New Notes to be received in the Exchange Offer.



                                 LEGAL MATTERS


     The validity of the New Notes offered hereby will be passed upon for the
Company by Stearns Weaver Miller Weissler Alhadeff & Sitterson, P.A., Miami,
Florida.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and
Stockholders of MasTec, Inc.
Miami, Florida


We have audited the accompanying consolidated balance sheets of MasTec, Inc.
and subsidiaries as of December 31, 1996 and 1995, and the related consolidated
statements of income, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.


We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.


In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of MasTec, Inc. and
subsidiaries as of December 31, 1996 and 1995, and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1996, in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES


NATURE OF BUSINESS


     MasTec, Inc. (the "Company" or "MasTec") is one of the world's leading
contractors specializing in the build-out of telecommunications infrastructure.
The Company's principal business consists of the design, installation and
maintenance of the outside physical plant ("outside plant") for telephone and
cable television communications systems, including the installation of aerial,
underground and buried copper, coaxial and fiber optic cable networks and the
construction of wireless antenna networks for telecommunications service
companies such as local exchange carriers, competitive access providers, cable
television operators, long-distance carriers, and wireless phone companies. The
Company also installs central office equipment and designs, installs and
maintains integrated voice, data and video local and wide area networks inside
buildings ("inside wiring"). The Company believes it is the largest independent
contractor providing telecommunications infrastructure construction services in
the United States and Spain and one of the largest in Argentina, Chile and
Peru.


     The Company is able to provide a full range of infrastructure services to
its telecommunications company customers. Domestically, the Company provides
outside plant services to local exchange carriers such as BellSouth
Telecommunications, Inc. ("BellSouth"), U.S. West Communications, Inc., SBC
Communications, Inc., United Telephone of Florida, Inc. (a subsidiary of Sprint
Corporation) and GTE Corp. At December 31, 1996, MasTec had 21 exclusive,
multi-year service contracts ("master contracts") with regional bell operating
companies ("RBOCs") and other local exchange carriers to provide all of their
outside plant requirements up to a specific dollar amount per job and within
certain geographic areas. Internationally, the Company provides through its
wholly owned subsidiary Sistemas e Instalaciones de Telecomunicacion, S.A.
("Sintel") outside plant services, turn-key switching system installation and
inside wiring services to Telefonica de Espana, S.A. ("Telefonica") under
multi-year contracts similar to those in the U.S.


     The Company was formed through the combination of Church & Tower and
Burnup & Sims, two established names in the U.S. telecommunications
construction services industry. On March 11, 1994, the shareholders of Church &
Tower acquired 65% of the outstanding common stock of Burnup & Sims in a
reverse acquisition (the "Burnup Acquisition"). Following the change in
control, the senior management of Burnup & Sims was replaced by Church & Tower
management and the name of Burnup & Sims was changed to "MasTec, Inc." Church &
Tower is considered the predecessor company to MasTec and, accordingly, the
results of Burnup & Sims subsequent to March 11, 1994 are included in the
results of the Company.


     In July and August 1997, Wilde Construction, Inc. and two related
companies ("Wilde") and AIDCO, Inc. ("Aidco") and one related company were
merged with and into the Company through an exchange of common stock. The
mergers were accounted for as poolings of interest. Accordingly, the Company's
consolidated financial statements include the results of Wilde and Aidco for
all periods presented (see Note 2).


MANAGEMENT'S ESTIMATES


     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

PRINCIPLES OF CONSOLIDATION


     The Consolidated Financial Statements include MasTec, Inc. and its
subsidiaries. All material intercompany accounts and transactions have been
eliminated. Certain prior year amounts have been reclassified to conform to the
current presentation.


INTERIM FINANCIAL STATEMENTS


     The consolidated financial statements of MasTec as of and for the nine
months ending September 30, 1996, and 1997, presented herein, have been
prepared by the Company without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission. As a result, certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted. The
financial statements reflect all adjustments (consisting of only normal
recurring adjustments) which, in the opinion of management, are necessary to
present fairly the consolidated financial position of the Company as of
September 30, 1997 and the results of its operations and cash flows for the
nine months ended September 30, 1996 and 1997.


FOREIGN CURRENCY


     The financial position and results of operations of the Company's foreign
subsidiaries are measured using local currency as the functional currency. The
Company translates foreign currency financial statements by translating balance
sheet accounts at the exchange rate on the balance sheet date and income
statement accounts at the average exchange rate for the period. Translation
gains and losses are recorded in stockholders' equity, and transaction gains
and losses are reflected in income.


REVENUE RECOGNITION


     Revenue and related costs for short-term telecommunications construction
projects are recognized as the projects are completed. Revenue generated by
certain long-term construction contracts are accounted for by the
percentage-of-completion method under which income is recognized based on the
estimated stage of completion of individual contracts. Losses, if any, on such
contracts are provided for in full when they become known. Billings in excess
of costs and estimated earnings on uncompleted contracts are classified as
current liabilities. Any costs in excess of billings are classified as current
assets.


     The Company also provides management, coordination, consulting and
administration services for construction projects. Compensation for such
services is recognized ratably over the term of the service agreement.


EARNINGS PER SHARE


     Earnings per share is computed by dividing net income by the weighted
average number of common and common equivalent shares during the period.
Outstanding stock options are considered common stock equivalents and are
included in the calculation using the treasury stock method.


     The Company's Board of Directors declared a three-for-two stock split in
the form of a stock dividend for stockholders of record on February 3, 1997
payable on February 28, 1997. All earnings per share amounts have been
calculated as if the dividend had occurred on December 31, 1993.

1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

     In February 1997, the Financial Accounting Standards Board (the FASB)
issued Statement of Financial Accounting Standards No. 128, EARNINGS PER SHARE
(FAS 128). FAS 128 specifies new standards designed to improve the EPS
information provided in financial statements by simplifying the existing
computational guidelines, revising the disclosure requirements, and increasing
the comparability of EPS data on an international basis. FAS 128 is effective
for financial statements issued for periods ending after December 15, 1997,
including interim periods. The Company does not believe it will have any
material effect on its EPS calculation.


CASH AND CASH EQUIVALENTS

     The Company considers all short-term investments with maturities of three
months or less when purchased to be cash equivalents. The Company places its
temporary cash investments with high credit quality financial institutions. At
times, such investments may be in excess of the F.D.I.C. insurance limits. The
Company has not experienced any loss to date on these investments.


INVENTORIES

     Inventories (consisting principally of material and supplies) are carried
at the lower of first-in, first-out cost or market.


PROPERTY AND EQUIPMENT, NET

     Property and equipment are recorded at cost, less accumulated
depreciation. Depreciation is provided using the straight-line method over the
estimated useful life of the assets as follows: buildings and improvements--5
to 20 years, and machinery and equipment--3 to 7 years. Leasehold improvements
are amortized over the shorter of the term of the lease or the estimated useful
lives of the improvements. Expenditures for repairs and maintenance are charged
to expense as incurred. Expenditures for betterments and major improvements are
capitalized. The carrying amounts of assets sold or retired and related
accumulated depreciation are eliminated in the year of disposal and the
resulting gains and losses are included in income.


INVESTMENTS

     The Company's investment in real estate located primarily in Florida,
acquired in connection with the Burnup Acquisition, is stated at its estimated
net realizable value. Investments in unconsolidated companies are accounted for
following the equity method of accounting (see Note 2).


ACCRUED INSURANCE

     The Company is self-insured for certain property and casualty and worker's
compensation exposure and, accordingly, accrues the estimated losses not
otherwise covered by insurance.


INCOME TAXES

     The Company records income taxes using the liability method. Under this
method, the Company records deferred taxes based on temporary taxable and
deductible differences between the tax bases of the Company's assets and
liabilities and their financial reporting bases. A valuation allowance is
established when it is more likely than not that some or all of the deferred
tax assets will not be realized.

RECENT ACCOUNTING PRONOUNCEMENTS


     In June 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive
Income" which establishes standards for reporting and display of comprehensive
income and its components (revenues, expenses, gains and losses) in a full set
of general-purpose financial statements. This statement requires that an
enterprise classify items of other comprehensive income by their nature in a
financial statement and display the accumulated balance of other comprehensive
income separately from retained earnings and additional paid-in capital in the
equity section of a statement of financial position. This statement is
effective for fiscal years beginning after December 15, 1997.


     In June 1997, the FASB issued SFAS No. 131 "Disclosure about Segments of
an Enterprise and Related Information" which establishes standards for public
business enterprises to report information about operating segments in annual
financial statements and requires those enterprises to report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes the standards for related disclosures about
products and services, geographic areas, and major customers. This statement
requires a public business enterprise report financial and descriptive
information about its reportable operating segments. The financial information
is required to be reported on the basis that it is used internally for
evaluating segment performance and deciding how to allocate resources to
segments. Operating segments are components of an enterprise about which
separate financial information is available that is evaluated regularly by the
chief operating decision maker in deciding how to allocate resources and in
assessing performance. This statement is effective for financial statements for
periods beginning after December 15, 1997.


     Management is currently evaluating the requirements of SFAS No. 130 and
No. 131 and their applicability to the Company.


2. ACQUISITIONS AND INVESTING ACTIVITIES


INTERNATIONAL


Sistemas e Instalaciones de Telecomunicacion, S.A. ("Sintel")


     On April 30, 1996, the Company purchased from Telefonica, 100% of the
capital stock of Sistemas e Instalaciones de Telecomunicacion, S.A. ("Sintel"),
a company engaged in telecommunications infrastructure construction services in
Spain, Argentina, Chile, and Peru. In Argentina, Chile and Peru, the Company
operates through unconsolidated joint ventures in which it holds interests
ranging from 38% to 50%. The purchase price for Sintel was Spanish Pesetas
("Pesetas") 4.9 billion (US$39.5 million at the then exchange rate of 124
Pesetas to one U.S. dollar). An initial payment of Pesetas 650 million ($5.1
million) was made at closing. An additional Pesetas 650 million ($4.9 million)
was paid on December 31, 1996, with the balance of the purchase price, Pesetas
3.6 billion (US$27.5 million), due in two equal installments on December 31,
1997 and 1998. Prior to April 30, 1996, as part of the terms of the purchase
and sale agreement with Telefonica, Sintel sold certain buildings to Telefonica
and Telefonica repaid certain tax credits and made a capital contribution to
Sintel collectively referred to as the "Related Transactions". The total
proceeds from the Related Transactions were approximately $41 million. The
assets and liabilities resulting from the acquisition are disclosed in the
supplemental schedule of non-cash investing and financing activities in the
Consolidated Statements of Cash Flows. The Sintel acquisition gives the Company
a significant international presence. See Note 9 regarding geographic
information.

2. ACQUISITIONS AND INVESTING ACTIVITIES--(CONTINUED)

     The following information presents the unaudited pro forma condensed
results of operations for the years ended December 31, 1996 and 1995 as if the
Company's acquisition of Sintel and the Related Transactions had occurred on
January 1, 1995. The Sintel acquisition has been treated as a "purchase" as the
term is used under generally accepted accounting principles. Management's
preliminary estimate of fair value approximated that of the carrying value of
the net assets acquired after reflecting a reserve for involuntary employee
terminations of $12.4 million and deferred taxes of $4.3 million. At December
31, 1996, approximately $2.7 million remained outstanding related to the
termination reserve. The pro forma results, which include adjustments to
increase interest expense resulting from the debt incurred pursuant to the
Sintel acquisition ($700,000 and $2.4 million for 1996 and 1995, respectively),
offset by the reduction in interest and depreciation expenses resulting from
the Related Transactions ($1 million and $4.4 million for 1996 and 1995,
respectively) and a tax benefit at 35% for each period are presented for
informational purposes only and are not necessarily indicative of the future
results of operations or financial position of the Company or the results of
operations or financial position of the Company had the Sintel acquisition and
the Related Transactions occurred January 1, 1995.

Inepar S/A-Sistemas de Telecomunicaoes, a newly formed Brazilian
telecommunications infrastructure contractor, for $29.4 million in cash payable
over eleven months and 250,000 shares of common stock. Goodwill related to this
acquisition amounted to $12.1 million is included in other long-term assets and
is being amortized over 15 years.


DOMESTIC


     During 1996 and 1995, the Company completed certain other acquisitions
which have also been accounted for under the purchase method of accounting and
the results of operations have been included in the Company's consolidated
financial statements from the respective acquisition dates. If the acquisitions
had been made at the beginning of 1996 or 1995, pro forma results of operations
would not have differed materially from actual results. Acquisitions made in
1996 were Carolina ComTec, Inc., a privately held company engaged in installing
and maintaining voice, data and video networks and

networks in the Western and Midwestern states. These acquisitions were
consummated through stock-for-stock exchanges in which the Company issued
approximately 1,371,000 shares of common stock. The Company has accounted for
these mergers under the pooling of interest method. Accordingly, historical
financial information has been restated to reflect the mergers as though they
occurred as of the earliest period presented. These acquisitions are
collectively referred to as the "Pooled Companies".


     During the nine months ended September 30, 1997, the Company completed
other acquisitions which have been accounted for under the purchase method of
accounting and the results of operations of which have been included in the
Company's condensed consolidated financial statements from the respective
acquisition dates. If the acquisitions had been made at the beginning of 1997
or 1996, pro forma results of operations would not have differed materially
from actual results. Acquisitions made in 1997 were Kennedy Cable Construction,
Inc., GJS Construction Co. d/b/a Somerville Construction and Shanco
Corporation, three contractors servicing multiple systems operators such as
Time Warner, Marcus Cable Co. and Cox Communications in a number of states

INVESTING ACTIVITIES


     In July 1996, the Company contributed its 36% ownership interest in
Supercanal, S.A., a cable television operator in Argentina, to a holding
company. Concurrently, Multicanal, S.A., one of the leading cable television
operators in Argentina, acquired a 20% interest in the holding company for
approximately $17 million in cash. The Company's interest in the holding
company was reduced to approximately 28.8% as a result of Multicanal's
investment. At December 31, 1996, the Company's investment was $16.0 million.


     In July 1995, the Company made a $25 million non-recourse term loan to

S.A. ("Conecel"), one of two cellular phone operators in the Republic of
Ecuador. In June 1997, the Company converted its loan and accrued interest into
the stock of the holding company. In December 1997, the Company sold its
investment for $20.0 million in cash and the right to receive Conecel
non-voting stock upon a public offering by Conecel.

     Not included in the preceding table at December 31, 1995 and 1996 is
approximately $2.2 million and $1.9 million, respectively, in capital leases
related to discontinued operations (see Note 13).


     In June 1997, the Company obtained a $125 million revolving credit
facility ("Revolving Credit Facility"), from a group of financial institutions
led by BankBoston, N.A. maturing on June 9, 2000 to replace the Fleet Credit
Facility and certain other domestic debt. As a result of the prepayment of the
Fleet Credit Facility, deferred financing costs and a termination fee totaling
$690,000 were expensed in the second quarter of 1997.


     Additionally, the Company has several credit facilities denominated in
Pesetas, one of which is a revolving credit facility with a wholly-owned
finance subsidiary of Telefonica. Interest on this facility accrues at MIBOR
(Madrid interbank offering rate) plus .30%. At December 31, 1996 and September
30, 1997, the Company had $82.1 million (11.3 billion Pesetas) and $55.8
million (8.3 billion Pesetas), respectively, of debt denominated in Pesetas,
including $27.4 million and $24.2 million, respectively remaining under the
acquisition debt incurred pursuant to the Sintel acquisition (see Note 2).

5. DEBT--(CONTINUED)

     Debt agreements contain, among other things, restrictions on the payment
of dividends and require the observance of certain financial covenants such as
minimum levels of cash flow and tangible net worth.


     In May 1996, the Company called its 12% Convertible Subordinated
Debentures (the "Debentures") effective June 30, 1996. The Debentures were
converted into Common Stock increasing the number of shares outstanding by
690,456.


     At December 31, 1996 debt matures as follows:

6. STOCK OPTION PLANS


     The Company's only employee stock option plan currently in effect is the
1994 Stock Incentive Plan (the "1994 Plan"). However, options which were
outstanding under the Company's 1976 and 1978 stock option plans at the time of
the Burnup Acquisition remain outstanding in accordance with the terms of the
respective plans. Approximately 49,200 shares have been reserved for and may
still be issued in accordance with the terms of such plans. Compensation
expense of $589,000 and $51,000 was recorded in 1996 and 1995, respectively,
related to the 1976 plan. Shares underlying stock options and exercise prices
have been adjusted to reflect the three-for-two stock split declared in 1997 by
the Board of Directors.


     The 1994 Plan authorizes the grant of options or awards of restricted
stock up to 1,200,000 shares of the Company's Common Stock, of which 300,000
shares may be awarded as restricted stock. As of December 31, 1996, options to
purchase 732,000 shares had been granted. Options become exercisable over a
five year period in equal increments of 20% per year beginning the year after
the date of grant and must be exercised within ten years from the date of
grant. Options are issued with an exercise price no less than the fair market
value of the Common Stock at the grant date.


     The Company also adopted the 1994 Stock Option Plan for Non-Employee
Directors (the "Directors' Plan"). The Directors' Plan authorized the grant of
options to purchase up to 600,000 shares of the Company's Common Stock to the
non-employee members of the Company's Board of Directors. Options to purchase
112,500 shares have been granted to Board members through 1996. The options
granted become exercisable ratably over a three year period from the date of
grant and may be exercised for a period of up to ten years beginning the year
after the date of grant at an exercise price equal to the fair market value of
such shares on the date the option is granted.


     In addition, during 1994 options to purchase 150,000 shares of Common
Stock at $3.83 per share were granted to a director outside the Directors' Plan
in lieu of the Director's Plan and annual fees paid

to the director. Compensation expense of $42,500 in connection with the
issuance of this option is being recognized annually over the five year vesting
period. The options are exercisable ratably over a five year period beginning
the year after the date of grant and may be exercised for a period of up to ten
years beginning the year after the date of grant.

6. STOCK OPTION PLANS--(CONTINUED)

     As of December 31, 1996, the Company adopted the disclosure provisions of
Financial Accounting Standards Board Statement No. 123, "Accounting for
Stock-Based Compensation." Accordingly, the Company is required to disclose pro
forma net income and earnings per share both for 1996 and 1995 as if
compensation expense relative to the fair value of the options granted had been
included in earnings. The fair value of each option grant was estimated using
the Black-Scholes option-pricing model with the following assumptions used for
grants in 1996 and 1995, respectively: a five year expected life for all years;
volatility factors of 51% for both years; risk-free interest rates of 6.13% and
5.94%, respectively; and no dividend payments. Had compensation cost for the
Company's options plans been determined and recorded consistent with FASB
Statement No. 123, the Company's net income and earnings per share would have
been reduced to the pro forma amounts as follows:




                                                                   1995          1996
                                                               -----------   ------------
                                                                       
   Net income (loss):
   As reported, including pro forma tax adjustment .........     $ 2,671       $ 33,116
   Pro forma ...............................................       2,400         32,262
   Earnings per share:
   As reported, including pro forma tax adjustment .........     $  0.11       $   1.25
   Pro forma ...............................................     $  0.09       $   1.22


     The 1996 and 1995 pro forma effect on net income is not necessarily
representative of the effect in future years because it does not take into
consideration pro forma compensation expense related to grants made prior to
1995 and does not reflect a tax benefit related to the compensation expense as
such benefit would be reflected directly in stockholders' equity given that the
options are considered incentive stock options.


7. INCOME TAXES


     On March 11, 1994, the Company became a taxable corporation and the effect
of recognizing the change in tax status of approximately $435,000 is included
in the provision for income taxes for the year ended December 31, 1994.

     The net change in the valuation allowance for deferred tax assets in 1996
was an increase of $100,000. The change relates primarily to state capital
losses generated in the current year which management believes will more likely
than not be realized.

     Deferred tax assets of $2,096,000 and $1,068,000 for 1996 and 1995,
respectively, have been recorded in current assets in the accompanying
consolidated financial statements.

     A reconciliation of U.S. statutory federal income tax expense on the
earnings from continuing operations is as follows:

     No provision was made in 1996 for U.S. income taxes on the undistributed
earnings of the foreign subsidiaries as it is the Company's intention to
utilize those earnings in the foreign operations for an indefinite period of
time or repatriate such earnings only when tax effective to do so. At December
31, 1996, undistributed earnings of the foreign subsidiaries amounted to $12.5
million. If the earnings of such foreign subsidiaries were not indefinitely
reinvested, a deferred tax liability of $1.3 million would have been required.

7. INCOME TAXES--(CONTINUED)

     The Internal Revenue Service (the "IRS") is currently examining the tax
returns of Burnup & Sims for the fiscal years ended April 30, 1989 through
April 30, 1993. The Company has filed a protest with the appellate level of the
IRS regarding assessments made for the years 1989 through 1991. Adjustments, if
any, as a result of this audit will be recorded as an adjustment to purchase
accounting.


8. CAPITAL STOCK


     The Company has authorized 50,000,000 shares of Common Stock. At December
31, 1996 and 1995, 27,805,849 shares of Common Stock were issued, 26,992,169
and 25,453,619 shares were outstanding (adjusted for the stock split and
pooling transactions) (see Note 2), respectively, and 813,680 and 2,352,230
were held in treasury, at cost (after giving effect to the stock split paid in
the form of a dividend from treasury stock), respectively.


     At the date of the Burnup Acquisition, the Company transferred Church &
Tower's previously reported undistributed earnings and profits of approximately
$11,165,000 to capital surplus.


     At December 31, 1996 and 1995, the Company had 5,000,000 shares of
authorized but unissued preferred stock.


9. OPERATIONS BY GEOGRAPHIC AREAS


     The Company's principal source of revenue is derived from
telecommunications infrastructure construction services in the United States
and Spain. The Company did not have significant international operations in
1995 or 1994, accordingly, geographic information for 1996 and subsequent is
presented below:

9. OPERATIONS BY GEOGRAPHIC AREAS--(CONTINUED)

     There are no transfers between geographic areas. Operating income consists
of revenue less operating expenses, and does not include interest expense,
interest and other income, equity in earnings of unconsolidated companies,
minority interest and income taxes. Domestic operating income is net of
corporate general and administrative expenses. Identifiable assets of
geographic areas are those assets used in the Company's operations in each
area. Corporate assets include cash and cash equivalents, investments in
unconsolidated companies, net assets of discontinued operations, real estate
held for sale and notes receivable.


10. SIGNIFICANT CUSTOMERS AND CONCENTRATION OF CREDIT RISK


     The Company derives a substantial portion of its revenue from providing
telecommunications infrastructure services to Telefonica and to BellSouth.
During 1994 and 1995, the Company derived revenue from BellSouth of
approximately $48.3 million and $73.1 million, respectively. For the year ended
December 31, 1996, approximately 31% and 13% of the Company's revenue was
derived from services performed for Telefonica and BellSouth, respectively.
Revenue generated by Sintel from Telefonica is included from May 1, 1996 (see
Note 2). For the nine months ended September 30, 1996, the Company derived
approximately 28% and 15% of its revenue from services performed for Telefonica
and BellSouth, respectively. For the nine months ended September 30, 1997,
approximately 27% and 13% of the Company's revenue was derived from services
performed for Telefonica and BellSouth, respectively. Accounts receivable from
the Company's two largest customers at December 31, 1995 and 1996 were $19.3
million and $194.2 million, respectively. Although the Company's strategic plan
envisions diversification of its customer base, the Company anticipates that it
will continue to be dependent on Telefonica and its affiliates and BellSouth
for a significant portion of its revenue in the future.


11. COMMITMENTS AND CONTINGENCIES


     In December 1990, Albert H. Kahn, a stockholder of the Company, filed a
purported class action and derivative suit in Delaware state court against the
Company, the then-members of its Board of Directors, and National Beverage
Corporation ("NBC"), the Company's then-largest stockholder. The complaint
alleges, among other things, that the Company's Board of Directors and NBC
breached their respective fiduciary duties in approving certain transactions,
including the distribution in 1989 to the Company's stockholders of all of the
common stock of NBC owned by the Company and the exchange by NBC of shares of
common stock of the Company for certain indebtedness of NBC to the Company. The
lawsuit seeks to rescind these transactions and to recover damages in an
unspecified amount.


     In November 1993, Mr. Kahn filed a class action and derivative complaint
against the Company, the then-members of its Board of Directors, Church &
Tower, Inc. and Jorge L. Mas, Jorge Mas and Juan Carlos Mas, the principal
shareholders of Church & Tower, Inc. The 1993 lawsuit alleges, among other
things, that the Company's Board of Directors and NBC breached their respective
fiduciary duties by approving the terms of the acquisition of the Company by
the Mas family, and that Church & Tower, Inc. and its principal shareholders
had knowledge of the fiduciary duties owed by NBC and the Company's Board of
Directors and knowingly and substantially participated in the breach of these
duties. The lawsuit also claims derivatively that each member of the Company's
Board of Directors engaged in mismanagement, waste and breach of fiduciary
duties in managing the Company's affairs prior to the acquisition by the Mas
Family.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)


11. COMMITMENTS AND CONTINGENCIES--(CONTINUED)

     The Company believes that the allegations in each of the lawsuits are
without merit and intends to defend these lawsuits vigorously.


     In August 1997, the Company settled its lawsuit with BellSouth arising
from certain work performed by a subcontractor of the Company from 1991 to 1993
for nominal consideration.


     In November 1997, Church & Tower filed a lawsuit against Miami-Dade County
(the "County") in the Circuit Court of the Eleventh Judicial Circuit in and for
Dade County, Florida alleging breach of contract and seeking damages in
connection with the County's refusal to pay amounts due to Church & Tower under
a multi-year agreement to perform road restoration work for the Miami-Dade
Water and Sewer Department ("MWSD"), a department of the County, and the
County's wrongful termination of the agreement. The County has refused to pay
amounts due to Church & Tower under the agreement until alleged overpayments
under the agreement have been resolved. The County has also refused to award a
new road restoration agreement for MWSD to Church & Tower, which was the low
bidder for the new agreement. The Company believes that any amounts due to the
County under the existing agreement are not material and may be recoverable in
whole or in part from Church & Tower subcontractors who actually performed the
work and whose bills were submitted directly to the County.


     The Company is a party to other pending legal proceedings arising in the
normal course of business, none of which the Company believes is material to
the Company's financial position or results of operations.


     In 1990, Trilogy Communications, Inc. filed suit against Excom Realty,
Inc., a wholly owned subsidiary of the Company, for damages and declaratory
relief. The Company counterclaimed for damages. On May 1, 1995, the Company
settled its counterclaim for $1.3 million, which is recorded as other income in
the accompanying consolidated financial statements.


     In connection with certain contracts, the Company has signed certain
agreements of indemnity in the aggregate amount of approximately $100.2
million, of which approximately $62.3 million relate to the uncompleted portion
of contracts in process. These agreements are to secure the fulfillment of
obligations and performance of the related contracts.


     Federal, state and local laws and regulations govern the Company's
operation of underground fuel storage tanks. The Company is in the process of
removing, restoring and upgrading these tanks, as required by applicable laws,
and has identified certain tanks and surrounding soil which will require
remedial cleanups.


12. FAIR VALUE


     For certain of the Company's financial instruments, including cash and
cash equivalents, accounts and notes receivable, accounts payable and other
liabilities, the carrying amounts approximate fair value due to their short
maturities. Long-term floating rate notes are carried at amounts that
approximate fair value.


     The Company uses letters of credit to back certain insurance policies. The
letters of credit reflect fair value as a condition of their underlying purpose
and are subject to fees competitively determined in the market place.

12. FAIR VALUE--(CONTINUED)

     The estimated fair values may not be representative of actual values of
the financial instruments that could have been realized as of year end or that
will be realized in the future.


13. DISCONTINUED OPERATIONS AND REAL ESTATE HELD FOR SALE


     In the third quarter of 1995, the Company determined to concentrate its
resources and better position itself to achieve its strategic growth objectives
by disposing of all of the general products segment that the Company acquired
as part of the Burnup Acquisition. These operations and assets include
Southeastern Printing Company, Inc. ("Southeastern"), Lectro Products, Inc.
("Lectro") and Floyd Theatres, Inc. ("Floyd Theatres").


     In March 1995, the Company sold the indoor theater assets of Floyd
Theatres for approximately $11.5 million. A gain of $1.5 million, net of tax,
resulted from this transaction in the first quarter of 1995. In August 1995,
the Company sold the stock of Lectro for $11.9 million in cash and a note
receivable of $450,000. A gain of $5.9 million, net of tax, was recorded in the
third quarter of 1995 related to the sale of Lectro. In January 1997, the
Company sold the assets of Southeastern at its carrying value for approximately
$2.1 million in cash and a note for $500,000.


     As part of the acquisition of Harrison-Wright (see Note 2), the Company
purchased the assets of Utility Pre-cast, Inc. The Company intends to sell the
pre-cast business and accordingly has reflected the net assets of approximately
$4.2 million as a discontinued operation.


     Included in other current assets in the accompanying balance sheet is
approximately $15.7 million and $17.7 million of real estate held for sale at
December 31, 1996 and 1995, respectively.


     Discontinued operations include management's best estimates of the amounts
expected to be realized on the sale of these assets. While the estimates are
based on current negotiations, the amounts the Company will ultimately realize
could differ materially in the near term from the amounts assumed in arriving
at the loss on disposal of the discontinued operations.


     Summary operating results of discontinued operations, excluding net gains
on disposal and estimated loss during the phase-out period, are as follows (in
thousands):

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)


14. QUARTERLY FINANCIAL DATA (UNAUDITED)--(CONTINUED)

- ----------------
(1) Earnings per share amounts have been adjusted to reflect the three-for-two
    stock split declared by the Company's Board of Directors on February 28,
    1997 and shares issued in connection with two acquisitions accounted for
    under the pooling of interest method.
(2) The Company acquired Sintel (see Note 2) on April 30, 1996.
(3) In the third quarter of 1995, the Company recorded a special charge of
$15.4 million to write-down its real estate held for sale.
(4) In the fourth quarter of 1995, the Company recorded an additional charge of
    $7.7 million to write-down real estate held for sale and its investment in
    preferred stock.
(5) Earnings per share are computed independently for each of the quarters
    presented. Therefore, the sum of the quarterly per share data does not
    equal the total computed for the year due to changes in the weighted
    average number of shares outstanding.
(6) Amounts and earnings per share have been adjusted to reflect a pro forma
tax provision for two acquisitions accounted for under the pooling of interest
method which were previously S corporations.

                                    PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.


     The Company's Amended and Restated Certificate of Incorporation (the
"Certificate") provides that the Company shall indemnify to the fullest extent
authorized by the Delaware General Corporation Law (the "DGCL"), each person
who is involved in any litigation or other proceeding because such person is or
was a director or officer of the Company, against all expense, loss or
liability reasonably incurred or suffered in connection therewith. The
Company's By-laws provide that a director or officer may be paid expenses
incurred in defending any proceeding in advance of its final disposition upon
receipt by the Company of an undertaking, by or on behalf of the director or
officer, to repay all amounts so advanced if it is ultimately determined that
such director or officer is not entitled to indemnification.


     Section 145 of the DGCL permits a corporation to indemnify any director or
officer of the corporation against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement actually and reasonably
incurred in connection with any action, suit or proceeding brought by reason of
the fact that such person is or was a director or officer of the corporation,
if such person acted in good faith and in a manner that he reasonably believed
to be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, if he had no reason to believe
his conduct was unlawful. In a derivative action, (I.E., one brought by or on
behalf of the corporation), indemnification may be made only for expenses,
actually and reasonably incurred by any director or officer in connection with
the defense or settlement of such an action or suit, if such person acted in
good faith and in a manner that he reasonably believed to be in or not opposed
to the best interests of the corporation, except that no indemnification shall
be made if such person shall have been adjudged to be liable to the
corporation, unless and only to the extent that the court in which the action
or suit was brought shall determine that the defendant is fairly and reasonably
entitled to indemnity for such expenses despite such adjudication of liability.
 


     Pursuant to Section 102(b)(7) of the DGCL, the Company's Certificate
eliminates the liability of a director to the corporation or its stockholders
for monetary damages for such breach of fiduciary duty as a director, except
for liabilities arising (i) from any breach of the director's duty of loyalty
to the corporation or its stockholders, (ii) from acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL, or (iv) from any transaction from which
the director derived an improper personal benefit.


     The Company has obtained primary and excess insurance policies insuring
the directors and officers of the Company and its subsidiaries against certain
liabilities they may incur in their capacity as directors and officers. Under
such policies, the insurer, on behalf of the Company, may also pay amounts for
which the Company has granted indemnification to the directors or officers.

ITEM 22. UNDERTAKINGS.


     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this Registration Statement through
the date of responding to the request.


     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.


     The undersigned registrant hereby undertakes:


     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:


     (i) to include any prospectus required by section 10(a)(3) of the
       Securities Act of 1933 (the "Act");


     (ii) To reflect in the prospectus any facts or events arising after the
   effective date of the registration statement (or the most recent
   post-effective amendment thereof) which, individually or in the aggregate,
   represent a fundamental change in the information set forth 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.


     (iii) To include any material information with respect to the plan of
   distribution not previously disclosed in the registration statement or any
   material change to such information in the registration statement.


     (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.


     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.


                                      II-2


     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Act, each filing of the registrant's annual
reports pursuant to section 13(a) or section 15(d) of the Securities Exchange
Act (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.


     (1) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.


     (2) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.


     Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the 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 Act and will be governed by the final adjudication of such
issue.


                                      II-3
