BUSINESS

General

We are a leading end-to-end voice, video, data and energy network
infrastructure solution for a broad range of communications, broadband, energy
and other corporate clients. We have a diverse client base representing all the
major segments of the industries we serve. Our broad suite of services allows
our clients to connect with their customers. We design, build, install, maintain
and monitor internal and external networks, transmission facilities and data
storage centers supporting e-commerce and other communications, computing and
energy systems. We are a national services provider, operating from 200 service
locations throughout the United States and Canada. We also operate in Brazil
through a 51% owned joint venture.

Strategy

We believe we are one of the few national, multi-disciplinary
infrastructure providers capable of providing a comprehensive solution to our
clients' bandwidth infrastructure needs from basic installation and construction
to sophisticated engineering, design and integration. Our diverse and
long-standing client base, experienced management and integrated value added
service offering provide a stable base of repeat business and enable us to
quickly and efficiently meet client demands.

Our strategy is to use these competitive strengths to increase market share
in the fragmented network infrastructure industry by expanding relationships
with long-time clients across multiple service offerings. We also provide
turn-key solutions to new clients who are seeking a single source for their
infrastructure requirements. We are focused on leveraging our administrative
base and achieving other cost savings and efficiencies through better
utilization of our equipment, facilities and personnel and through economies of
scale. We continue to expand our capabilities and geographic scope through
selected acquisitions and investments although our primary focus is organic
growth. We believe these strategies will permit us to continue to grow
profitably. However, current economic conditions may impact our ability to grow
at historical levels.

Clients

Our clients include some of the largest and most prominent companies in the
communications and energy fields, including:

o incumbent local exchange carriers,
o telecommunications equipment vendors,
o competitive local exchange carriers,
o government agencies such as departments of transportation,
o cable television operators,
o data storage and co-location facilities providers,
o long distance carriers,
o public and private energy companies
o wireless service providers, and
o financial institutions and other corporate clients.

We have over 200 clients, none of which accounted for 10% or more of our
revenue in 2000. Our top 10 clients combined accounted for approximately 44% of
our domestic revenue. Representative clients include:





AT&T Corporation Lucent Technologies, Inc.
BellSouth Corporation NEC Corporation
Carolina Power and Light Company Qwest Communications International,Inc.
Charter Cable, Inc. SBC Communications, Inc.
Comcast Corporation Sprint Corp.
Cox Communications, Inc. Telergy, Inc.
Enron Corporation Texas Utilities Company
First Union Corporation Time Warner, Inc.
Georgia Department of Transportation Verizon Communications, Inc.
Global Crossing, Ltd. Williams Communications Group
Level 3 Communications, Inc.

We provide the majority of our services to our clients under master service
agreements, which typically are exclusive multi-year service agreements to
satisfy our client's network requirements up to a specified dollar amount per
job within defined geographic areas. We currently have 88 master service
agreements across all service lines. Revenue from master service agreements
represents approximately 50% of our annual domestic revenue.

Services

We market our services individually and in combination to provide the most
efficient and effective solution to meet our clients' demands, which
increasingly require resources from multiple disciplines. Through our unified
"MasTec"(R) brand and an integrated organizational structure designed to permit
rapid deployment of labor, equipment and materials, we are able quickly and
efficiently to allocate resources to meet client needs.

We offer our services under two broad categories organized around our
clients:

Datacom Network Services. We design, build, install, maintain and monitor
the physical facilities used to provide end-to-end voice, video and data service
from the provider's central office, switching center or cable television
head-end to the ultimate consumer's home or business. We provide these services
both externally on public or private rights-of-ways or in our clients' premises.
Our services include:

- comprehensive project management, coordination, consulting and
administration;

- designing, installing, testing and documenting switching and transmission
equipment and supporting components at point-of-presence locations;

- network route development, right of way and other site acquisition, and
permitting;

- designing conduit networks and fiber rings;

- placing and splicing fiber optic, coaxial and copper cable; excavating
trenches in which to place the cable; and furnishing and placing related
structures such as poles, anchors, conduits, manholes, cabinets and closures;

- placing drop lines from our clients' main distribution terminals to their
customer's home or business;

- installing set-top boxes, satellite dishes and other connection devices
in homes and businesses;

- erecting wireless communication towers, constructing related structures
and installing associated equipment;

- designing and installing intelligent traffic networks;

- engineering, furnishing and installing integrated voice, video and data
networks inside client premises as well as the infrastructure required to
support complex e-commerce solutions;



- systems integration, which includes selecting, configuring and installing
software, hardware and other computing and communications equipment and cabling
to provide an integrated computing and communications system;

- monitoring, maintaining and restoring clients' networks 24 hours a day,
seven days a week;

- network device security and optimization,

- procuring materials;

- providing acceptance testing and as-built documentation; and

- maintaining, upgrading, removing and replacing these systems.

Energy Network Services. We provide external network and energy
infrastructure services to public and private utilities. These services consist
of overhead and underground installation and maintenance of electrical and other
utilities' transmission and distribution networks, substation construction and
maintenance, right-of-way maintenance and restoration of asphalt and concrete
surfaces. These services are substantially similar to the services we provide to
our datacom clients, but the work often involves the installation and splicing
of high-voltage transmission and distribution lines.

Brazil. We operate in Brazil through a 51% joint venture which we
consolidate net of a 49% minority interest after tax. Our Brazilian operations
provide datacom infrastructure services to a diverse group of telecommunication
companies primarily in the heavily populated states of southern Brazil.

Backlog

At December 31, 2000, we had a backlog in our domestic operations of
approximately $1.5 billion as compared to a backlog of approximately $970.1
million at December 31, 1999. Our backlog consists of the uncompleted portion of
services we are to perform under project-specific contracts as well as estimated
work on master service agreements. We expect to complete substantially all of
our backlog at December 31, 2000 during the next 18 months.

Sales and Marketing

We have developed a marketing plan emphasizing the "MasTec"(R) registered
trade name and an integrated service offering to position ourselves as a
seamless, end-to-end nationwide infrastructure services solution providing basic
infrastructure to sophisticated engineering, design and integration. We believe
our long-standing relationships with our clients and reputation for reliability
and efficiency facilitates our repeat business. Our marketing efforts are
principally carried out by the management of our service lines, most of whom
have many years' experience in the industries they serve, both at the service
provider level and in some cases with the clients we serve. Our service line
leadership markets to existing and potential telecommunications and other
clients to negotiate new contracts or to be placed on lists of vendors invited
to submit proposals for master service agreements and individual projects. Our
executive management supplements their efforts at the national level. We also
market through commissioned salespeople and our corporate marketing department.

Safety and Insurance

We are committed to ensuring that our team members perform their work
safely and strive to instill safe work habits in all of our team members. We
evaluate our team members not only on the basis of the efficiency and quality of
their work but also on their safety records and the safety records of the
employees they supervise. We also hold regular training sessions and seminars
with our team members devoted to safe work practices. We have established a
company-wide safety committee to share best practices among our units and to
monitor and improve compliance with safety regulations.

The primary claims we face in our operations are workers' compensation,
automobile liability and various general liabilities. We maintain insurance
policies with respect to these claims, but these policies are subject to
deductibles for worker's compensation, automobile liability and general
liability up to $250,000 per claim. We have umbrella coverage up to a policy
limit of $25.0 million and stop loss coverage of $16.1 million for 2000 claims.
We actuarially determine any liabilities for unpaid claims and associated
expenses, including incurred but not reported losses, and reflect those
liabilities in our balance sheet as an accrued liability. We continually review
these claims and expenses and the appropriateness of the accrued liability.



Suppliers

Our clients supply the majority of the raw materials and supplies necessary
to carry out our contracted work, although we are increasingly supplying
materials and supplies on turnkey projects. We obtain materials and supplies for
our own account from independent third-party providers and do not manufacture
any significant amount of materials or supplies for resale. We are not dependent
on any one supplier for any materials or supplies that we obtain for our own
account. We have not experienced any significant difficulty in obtaining an
adequate supply of materials and supplies.

We also use independent contractors to perform portions of our services and
to manage work flow. These independent contractors typically are sole
proprietorships or small business entities. Independent contractors typically
provide their own employees, vehicles, tools and insurance coverage. We are not
dependent on any single independent contractor.

Competition

There is no dominant provider in the network infrastructure services
industry. The industry is highly fragmented and we compete with other companies
in most of the markets in which we operate ranging from small independent firms
servicing local markets to larger firms servicing regional markets, as well as
large national and international engineering firms and equipment vendors on
turnkey projects who subcontract work to companies other than us. Despite the
current trend toward outsourcing, we also face competition from existing or
prospective clients who employ in-house personnel to perform some of the same
types of services we provide. Historically, there have been relatively few
significant barriers to entry into the markets in which we operate and, as a
result, any organization that had adequate financial resources and access to
technical expertise may become one of our competitors. We are, however, one of
the few providers with a nationwide comprehensive services offering.

We believe our clients consider a number of factors in choosing a service
provider, including technical expertise and experience, financial and
operational resources, nationwide presence, industry reputation and
dependability. Because of the highly competitive bidding environment for
infrastructure services, price historically has often been the principal factor
in determining whether the services provider is awarded the work on smaller,
less complex projects. Smaller competitors are sometimes able to win bids for
these projects based on price alone due to their lower overhead costs. We
believe our size, nationwide presence, integrated value added service offering,
financial strength and reputation provide a competitive advantage in obtaining
larger, more complex infrastructure projects and gaining market share in the
fragmented infrastructure services industry.

Regulation

Our operations are subject to various federal, state and local laws,
including:

- Contractor licensing requirements;
- Building and electrical codes;
- Permitting and inspection requirements; and
- Regulations related to labor relations, worker safety,
and environmental protection


We believe we have all material licenses and permits required to conduct
our operations and that we are in substantial compliance with all applicable
regulatory requirements.

Employees

As of December 31, 2000, we had approximately 9,800 team members in North
American operations and approximately 2,600 in Brazil. Approximately 600 of our
team members are represented by a labor union, principally the Communication
Workers of America or the International Brotherhood of Electrical Workers. We
believe that our employee relations are good.


Recruiting. Our primary hiring sources for our team members include
promotion from within, team member referrals, print and Internet advertising and
direct recruiting. We attract and retain team members by offering technical
training opportunities, bonus opportunities, stock ownership, competitive
salaries, and a comprehensive benefits package. Our "MasTec"(R) brand and
integrated service offering also has created a unified corporate culture that we
believe helps attract and retain team members. Team members are exposed to
numerous technologies being deployed by our clients which serves as a
recruitment tool. We attract talent from numerous sources including higher
learning institutions, colleges, and industry.

Training and Career Development. We believe that our continuous focus on
training and career development helps us to retain our team members. Team
members participate in on-going educational programs, many of which are
internally developed, to enhance their technical and management skills through
classroom and field training. Manufacturers of telecommunications equipment also
sponsor training programs covering the installation and maintenance of their
equipment, which our team members regularly attend. We also provide
opportunities for promotion and mobility within our integrated service
organization that we believe helps retain our team members.

We believe our corporate culture and organizational structure creates a
cooperative, entrepreneurial atmosphere and shared vision. We are dedicated to
maintaining an innovative, creative and empowering corporate culture that
provides our team members with personal and professional growth opportunities.

Other

We are organized as a Florida corporation. Our predecessor company was
formed in 1969, and we have operated as "MasTec" since 1994.


EXECUTIVE OFFICERS


The following is a list of the names and ages of all of our executive
officers, indicating all positions and offices they hold with us. Our executive

since January 1998. Mr. Citron was the managing partner of Triscope Capital LLC,
a private investment partnership, from January to December 1998 and Chairman of
the Board of Directors of the United States subsidiary of Proventus AB, a

Operating Officer, he served as President of our Broadband Services group from
January 1997. Mr. Shanfelter has been in the datacom infrastructure industry

September 1998 and a Manager from July 1994 to July 1997 with
PricewaterhouseCoopers LLP, a public accounting firm.


PROPERTIES

Our corporate headquarters are located in a 60,000 square foot building
owned by us in Miami, Florida. Our principal operations are conducted from
approximately 200 service facilities, none of which we believe is material to
our operations because most of our services are performed in the clients'
premises or on public rights of way. In addition, we believe that equally
suitable alternative locations are available in all areas where we currently
conduct business.

We also own a substantial amount of equipment, which at December 31, 2000
had a gross book value of $269.0 million. This equipment includes vans, trucks,
tractors, trailers, bucket trucks, backhoes, bulldozers, directional boring
machines, digger derricks, cranes and testing equipment and software. We obtain
our equipment from various third-party vendors, none of which we depend upon,
and have not experienced any difficulties in obtaining desired equipment.

LEGAL PROCEEDINGS

We have filed lawsuits in Florida state court against a subsidiary of
Artcom Technologies, Inc., a holding company for a Spanish infrastructure
provider that we formerly owned, to recover more than $5.0 million due under a
promissory note and for breach of contract. We are also pursuing other claims
against Artcom affiliates totalling approximately $4.0 million. Artcom has
responded by suing us in federal court in Florida to recover approximately $6.0
million (subject to trebling) it alleges we received as a result of certain
allegedly unauthorized transactions by two former employees of Artcom that
occurred after we sold the company.

In January 2001, we filed suit in Florida state court against Broward
County, Florida, to recover approximately $5.0 million for work performed to
construct a detention facility for the Broward Sheriff's Office ("BSO"). The BSO
has filed a separate lawsuit in response to our lawsuit claiming $13.0 million
in damages for alleged delays in constructing the facility.

In November 1997, we filed a suit against Miami-Dade County in Florida
state court alleging breach of contract and seeking damages exceeding $3.0
million in connection with the county's refusal to pay amounts due to us under a
multi-year agreement to perform road restoration work for the Miami-Dade Water
and Sewer Department ("MWSD"), a department of the county. The county has
counterclaimed against us seeking unspecified damages.

We are a party to other pending legal proceedings arising in the normal
course of business, none of which we believe is material to our financial
position or results of operations.



SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

None.

Stock Exchange under the symbol "MTZ." The following table sets forth, for the
quarters indicated, the high and low sale prices of the common stock, as
reported by the New York Stock Exchange.



Year Ended December 31,

Holders. As of December 31, 2000, there were 4,527 shareholders of record
of the common stock.

Dividends. We have not declared cash dividends since our inception and we
do not anticipate paying any cash dividends in the foreseeable future, but
intend instead to retain any future earnings for reinvestment in our business.
On February 28, 1997 and June 19, 2000 we effected three-for-two splits of our
outstanding shares of common stock by paying each of our shareholders a stock
dividend of one share of common stock for every two shares of common stock held
by the shareholder on the record date for each split. We paid cash in lieu of
fractional shares resulting from the stock splits based on the last sale price
as reported on the New York Stock Exchange on the record date. All references in
this Annual Report to shares of common stock or share prices have been adjusted
to give retroactive effect to the stock splits.

Any future determination as to the payment of dividends will be made at the
discretion of our Board of Directors and will depend upon our operating results,
financial condition, capital requirements, general business conditions and such
other factors as the Board of Directors deem relevant. In addition, certain
credit agreements to which we are a party prohibit us from paying dividends or
making other distributions on the common stock without the prior written consent
of the lenders under such credit agreements. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and Capital
Resources."

(1) Includes the results of operations of our Spanish subsidiary from May 1,
1996, 87% of which we sold effective December 31, 1998. Included in 1998
are severance charges relating to our Spanish operations of $13.4 million,
of which $1.9 million is reflected in costs of revenue and $11.5 million in
general and administrative expenses, and a loss of $9.2 million related to
the sale of our Spanish subsidiary. Our effective tax rate for the year
ended December 31, 1998 was mainly affected by a tax liability of
approximately $7.8 million resulting from the sale of 87% of our Spanish
subsidiary, the non-deductibility of the amortization of intangibles and
the non-deductibility of other expenses. Because of the sale, the balance
sheet data as of December 31, 1998 does not include the financial position
of our Spanish operations.

partial sale of our interest in an Ecuadorian cellular company.
(5) Included in 1999 is a write-down of $10.2 million related to international
assets held for sale.
(6) Included in 2000 is a write-down and other charges of $35.9 related
primarily to non-core assets, offset by a gain on sale of $9.6 million.

effected on February 28, 1997 and June 19, 2000.




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

General

We are a leading end-to-end voice, video, data and energy network
infrastructure solution for a broad range of communications, broadband, energy
and other corporate clients. We have a diverse client base representing all the
major segments of the industries we serve. Our broad suite of services allows
our clients to connect with their customers. We design, build, install, maintain
and monitor internal and external networks, transmission facilities and data
storage centers supporting e-commerce and other communications, computing and
energy systems. We are a national services provider, operating from 200 service
locations throughout the United States and Canada. We also operate in Brazil
through a 51% owned joint venture.

We believe we are one of the few national, multi-disciplinary
infrastructure providers capable of providing a comprehensive solution to our
clients' bandwidth infrastructure needs from basic installation and construction
to sophisticated engineering, design and integration. Our diverse and
long-standing client base, experienced management and integrated value added
service offering provide a stable base of repeat business and enable us to
quickly and efficiently adapt to meet client demands.

Our revenue has increased significantly in the past five years through both
acquisitions and internal growth. We intend to continue to emphasize internal
growth, although we also intend to grow through selected acquisitions following
a disciplined model to take advantage of consolidation opportunities in the
fragmented infrastructure services industry in the United States. We regularly
evaluate potential acquisition opportunities, but we are not currently engaged
in any negotiations to make any material acquisitions. However, current economic
conditions may impact our ability to grow at historical levels.

For the year ended December 31, 2000, our top 10 clients combined account
for approximately 44% of our domestic revenue.


We report our operations in four segments:

- Datacom network services,
- Energy network services,
- International, and
- Other

Datacom network services includes services to:

- Telecommunication companies, - Departments of Transportation,
- Equipment vendors, - Cable TV operators,
- Corporations, - Broadband providers,
- Wireless providers,

to meet their datacom network needs. Energy network services includes
services to public and private energy companies that are substantially similar
to datacom services. International operations currently consist of services
rendered in Brazil where we operate a 51% joint venture which we consolidate net
of a 49% minority interest after tax.

Our primary types of contracts with our clients include:

- design and installation contracts for specific projects,

- master service agreements for all specified design, installation
and maintenance services within a defined geographic territory,
and

- turnkey agreements for comprehensive design, engineering,
installation, procurement and maintenance services.



The majority of our contracts, whether master service agreements or
contracts for specific projects, provide that we will furnish a specified unit
of service for a specified unit of price. We recognize revenue as the related
work is performed. Turnkey agreements are invoiced on a unit basis. A portion of
our work is performed under percentage-of-completion contracts. Under this
method, revenue is recognized on a cost-to-cost method based on the percentage
of total cost incurred to date in proportion to total estimated cost to complete
the contract. We also recognize revenue for monitoring services and for project
management services ratably over the term of the agreement. Clients are billed
with varying frequency-weekly, monthly or upon milestones.

We perform the majority of our services under master service agreements,
which typically are exclusive service agreements to provide all of the client's
network requirements up to a specified dollar amount per job within defined
geographic areas. These contracts are generally for two to three years but are
typically subject to termination at any time upon 90 to 180 days prior notice.
Each master service agreement contemplates hundreds of individual projects
generally valued at less than $100,000 each. These master service agreements are
typically awarded on a competitive bid basis, although clients are sometimes
willing to negotiate contract extensions beyond their original terms without
re-bidding. Master service agreements are invoiced on a unit basis as work is
completed. We currently have 88 master service agreements across all segments.
Revenue from multi-year master service agreements represent approximately 50% of
our annual domestic revenue.

Direct costs include:

- operations payroll and benefits, - fuel,
- subcontractor costs, - equipment rental, and
- materials not provided by our clients, - insurance.

Our clients generally supply materials such as cable, conduit and telephone
equipment, although on some turnkey projects, we supply these materials.

General and administrative costs include all costs of our management
personnel, rent, utilities, travel and business development efforts and back
office administration such as financial services, insurance administration,
professional costs and clerical and administrative overhead.

Many of our contracts require performance and payment bonds. Contracts
often include payment provisions under which 5% to 10% is withheld from payment
until the contract work has been completed. We typically agree to indemnify our
clients against adverse claims and warrant the quality of our services for
specified time periods, usually one year.

Year Ended December 31, 2000 Compared to Year Ended December 31, 1999

The following table states revenue and change in revenue by operating
segments, in dollar and percentage terms (dollars in thousands):


Change
1999 2000 $ %
-------------- -------------- -------------- -------------

Datacom network services $ 849,201 $ 1,132,599 $ 283,398 33.4
Energy network services 153,179 142,386 (10,793) (7.1)
International 55,220 55,311 91 0.2
Other 1,422 - (1,422) (100.0)
-------------- -------------- --------------
$ 1,059,022 $ 1,330,296 $ 271,274
============== ============== ==============



Our revenue was $1.3 billion for the year ended December 31, 2000, compared
to $1.1 billion for the same period in 1999, representing an increase of $271.3
million or 25.6%, primarily from organic growth. The fastest growing operating
segment is our datacom network services segment primarily due to the increased
demand for bandwidth by end-users which has spurred increased network
construction and upgrades by our clients. We also are experiencing growth in
services provided at central office facilities resulting from regulatory
co-location requirements to open these facilities to new competitors. Revenue
generated by our energy network services segment decreased because we did not
pursue certain less profitable work in an effort to improve margins in the
future.

Our costs of revenue were $1.0 billion or 76.5% of revenue for the year
ended December 31, 2000, compared to $803.8 million or 75.9% of revenue for the
same period in 1999. In 2000, margins were impacted by adverse weather.

Depreciation was $52.4 million or 4.0% of revenue for the year ended
December 31, 2000, compared to $46.4 million or 4.4% of revenue for the same
period in 1999. The decline in depreciation as a percentage of revenue in 2000
was due to our ability to more efficiently utilize our equipment.

Amortization was $11.0 million or 0.8% of revenue for the year ended
December 31, 2000, compared to $9.7 million or 0.9% of revenue for the same
period in 1999. Amortization of goodwill net of tax was $7.8 million in 2000 and
$7.3 million in 1999.

General and administrative expenses were $98.5 million or 7.4% of revenue
for the year ended December 31, 2000, compared to $91.9 million or 8.7% of
revenue for the same period in 1999. The decline in general and administrative
expenses as a percentage of revenue in 2000 was due primarily to our ability to
support higher revenue with a comparatively lower administrative base.

Interest expense, net of interest income, was $13.3 million or 1.0% of
revenue for the year ended December 31, 2000, compared to $17.3 million or 1.6%
of revenue for the same period in 1999. The decrease in net interest expense of
$4.0 million was due primarily to the repayment of debt under our revolving
credit facility with a portion of the $126.0 million in net proceeds from our
offering of 3.75 million shares in February 2000.

Other expense in 2000 included primarily write-downs of $35.9 million of
international non-core assets, offset by a gain of $9.6 million on the sale of
our PCS system in Latin America. Reflected in other expense, net for the year
ended December 31, 1999, are charges related to non-core assets of approximately
$13.8 million due to disposal or write-down to net realizable value. We also
reserved $1.0 million for a 1994 lawsuit from a predecessor company following a
$1.1 million judgment awarded in October 1999. Offsetting these amounts was a
fee of $4.8 million collected from a telecommunications client related to
extensions to the maturity date of a client financing arrangement.

For the year ended December 31, 2000, our effective tax rate was
approximately 40.5% for North American operations and 33% for Brazilian
operations, compared to 41.5% and 33% in 1999 for North American and Brazilian
operations, respectively.

Year Ended December 31, 1999 Compared to Year Ended December 31, 1998

The following table states revenue and change in revenue by operating
segments, in dollar and percentage terms (dollars in thousands):


Change
1998 1999 $ %
------------- -------------- ------------- ----------

Datacom network services $ 545,485 $ 849,201 $ 303,716 55.7
Energy network services 120,218 153,179 32,961 27.4

------------- -------------- -------------
$ 811,582 $ 1,059,022 $ 247,440
============= ============== =============



Our revenue was $1.06 billion for the year ended December 31, 1999,
compared to $811.6 million for the same period in 1998, representing an increase
of $247.4 million or 30.5%. The fastest growing operating segment is our datacom
network services segment primarily due to the increased demand for bandwidth by
end-users which has spurred increased network construction and upgrades by our
clients. We experienced growth in services provided at central office facilities
resulting from regulatory co-location requirements to open central office
facilities to new competitors. Our energy network services segment grew
primarily through two acquisitions made in March and April of 1998. Brazilian
revenue decreased primarily due to the devaluation of the Brazilian real and to
a reduction in work performed. Revenue in local currency was R$96.0 million real
during the year ended December 31, 1999, compared to R$160.4 million real for
the same period in 1998, representing a decrease of 40.1%.

Our costs of revenue were $803.8 million or 75.9% of revenue for the year
ended December 31, 1999, compared to $619.4 million or 76.3% of revenue for the
same period in 1998. In 1999, margins in our Brazilian operations improved as a
result of amounts paid by a client for costs incurred during prior periods for
which no revenue had been recorded due to the uncertainty of its collection.
North American margins were impacted by increased revenue derived from the sale
of materials on turnkey projects, which carry a lower mark-up. Additionally, our
energy network services segment experienced reduced productivity by unusually
poor weather conditions in the mid-Atlantic states during the third quarter of
1999. Adverse weather conditions impacted productivity during the first quarter
of 1998.

Depreciation was $46.4 million or 4.4% of revenue for the year ended
December 31, 1999, compared to $29.6 million or 3.6% of revenue for the same
period in 1998. The increased depreciation expense as a percent of revenue
resulted from our investment in our fleet to support current and projected
revenue growth.

Amortization was $9.7 million or 0.9% of revenue for the year ended
December 31, 1999, compared to $11.0 million or 1.4% of revenue for the same
period in 1998.

General and administrative expenses were $91.9 million or 8.7% of revenue
for the year ended December 31, 1999, compared to $89.4 million or 11.0% of
revenue for the same period in 1998. The decline in general and administrative
expenses as a percent of revenue for the year ended December 31, 1999 was due
primarily to our ability to support higher revenue with a comparatively lower
administrative base.

Interest expense, net of interest income, was $17.3 million or 1.6% of
revenue for the year ended December 31, 1999, compared to $15.3 million or 1.9%
of revenue for the same period in 1998. The increase in net interest expense of
$2.0 million was due primarily to increased indebtedness to support additional
growth.

Reflected in other expense, net for the year ended December 31, 1999, are
charges related to non-core assets of approximately $13.8 million. We also
reserved $1.0 million for a 1994 lawsuit from a predecessor company following a
$1.1 million judgment awarded in October 1999. Offsetting these amounts was a
fee of $4.8 million collected from a telecommunications client related to
extensions to the maturity date of a vendor financing arrangement. Other expense
in 1998 includes predominantly a $33.8 million charge related to signing bonuses
and extended non-competition payments made under agreements with operating
management that could not be attributed to future services.

For the year ended December 31, 1999, our effective tax rate was
approximately 41.5% for North American operations and 33% for Brazilian
operations, compared to 40% and 33% in 1998 for North American and Brazilian
operations, respectively.



Spain

The following table states the results of operations of our Spanish
operations for the year ended December 31, 1998, in dollar and percentage of

administrative expenses.

Financial Condition, Liquidity and Capital Resources

Our primary liquidity needs are for working capital, capital expenditures,
acquisitions and investments, and debt service. Our primary sources of liquidity
are cash flows from operations and borrowings under revolving lines of credit.

Net cash used in operating activities was $11.9 million for the year ended
December 31, 2000, compared to cash provided by operations of $120.1 million for
the same period in 1999 and cash used of $13.9 million in 1998. Net cash used in
operating activities in 2000 was due principally to increased working capital
needs as a result of growth in revenue and changes in client mix. Cash provided
by operations in 1999 included collections of $81.4 million from prior periods
from a client to which we were providing vendor financing. From time to time, in
exchange for one or more of long-term exclusive infrastructure services
agreements, interest, financing and other fees, and warrants or other equity
interests in the client, we may grant payment terms typically for six to
eighteen months to our clients. At December 31, 2000, we had $31.5 million under
these arrangements.

We have a credit facility that provides for borrowings up to an aggregate
of $100.0 million. Amounts outstanding under the credit facility mature on June
9, 2002. We are required to pay an unused facility fee ranging from .25% to .50%
annually on the facility, depending upon certain financial covenants. The credit
facility contains customary events of default and covenants which prohibit,
among other things, making investments in excess of a specified amount,
incurring additional indebtedness in excess of a specified amount, paying
dividends in excess of a specified amount, making capital expenditures in excess
of a specified amount, creating liens, prepaying other indebtedness, including
our 7.75% senior subordinated notes, and engaging in certain mergers or
combinations without the prior written consent of the lenders. The credit
facility also provides that we must maintain financial ratio coverages at the
end of each fiscal quarter such as debt to earnings and earnings to interest
expense.

We also have $200 million, 7.75% senior subordinated notes due in February
2008, with interest due semi-annually.


During 2000, we invested $52.6 million primarily in our fleet to support
revenue growth. We collected $54.1 million in net proceeds related to assets
sold, primarily from the sale of our PCS system in Latin America and our Spanish
operations. We also invested $55.3 million in acquisitions and investments and
contingent consideration from prior acquisitions during the year. We have
reflected in other current liabilities contingent consideration of $35.0 million
that we expect will be paid during 2001.

Seasonality

Our North America operations have historically been seasonally slower in
the first quarter of the year. During the last two years, we have generally
experienced sequential increases in revenue following the first quarter of every
year. This seasonality is primarily the result of client budgetary constraints
and preferences and the effect of winter weather on external network activities.
Some of our U.S. clients, particularly the incumbent local exchange carriers,
tend to complete budgeted capital expenditures before the end of the year and
defer additional expenditures until the following budget year. Revenue in local
currency from our Brazilian operations is not expected to fluctuate seasonally.

Impact of Inflation

The primary inflationary factor affecting our operations is increased labor
costs. We have not experienced significant increases in labor costs to date.
Competition for qualified personnel could increase labor costs for us in the
future. Our Brazilian operations may, at times in the future, be exposed to high
inflation or currency devaluations.

MASTEC, INC.
CONSOLIDATED STATEMENTS OF CASH FLOWS-(Continued)


In 1998, we disposed of our Spanish operations. The book value of the net
assets totaled $65.6 million and was comprised primarily of $137.3 million of
accounts receivable, $17.3 million of property and equipment, other assets and
inventories of $43.3 million and cash of $2.2 million, offset by $134.5 million
of assumed liabilities. We retained a 13% interest valued at $4.1 million
resulting in $61.5 million in net assets sold at $52.3 million resulting in a
loss of $9.2 million. The terms of the sale included $25.0 million in the form
of debt assumed by the buyers and we financed $27.3 million which was
substantially collected in 1999.

In 1998, we issued approximately 0.16 million shares of common stock
primarily as payment for contingent consideration related to 1997 acquisitions.
In addition, we issued approximately 0.1 million shares as bonuses to certain
employees and fees to directors. In 1998, we completed certain acquisitions
which have been accounted for as purchases. The fair value of the net assets
excluding goodwill acquired totaled $36.2 million and was comprised primarily of
$35.2 million of accounts receivable, $27.2 million of property and equipment,
$8.0 million of other assets and $5.0 million in cash, offset by $39.2 million
of assumed liabilities. The excess of the purchase price over the net assets
acquired was $55.3 million and was allocated to goodwill.

In 1999, we completed certain acquisitions which have been accounted for as
purchases. The fair value of the net assets excluding goodwill acquired totaled
$3.75 million and was comprised primarily of $7.0 million of accounts
receivable, $2.4 million of property and equipment, $0.68 million of other
assets and $0.27 million in cash, offset by $6.6 million of assumed liabilities.
The excess of the purchase price over the fair value of net assets acquired was
$7.4 million and was allocated to goodwill. The total purchase price of $11.2
million was primarily paid in cash. We also issued 0.53 million shares of common
stock with a value of $11.3 million related to the payment of contingent
consideration from earlier acquisitions. Of the $11.3 million, $2.3 million was
recorded as a reduction of other current liabilities and $9.0 million as
additional goodwill. Additionally, $7.8 million of contingent consideration was
paid in cash and was recorded as goodwill.

In 2000, we completed certain acquisitions which have been accounted for as
purchases. The fair value of the net assets acquired excluding goodwill totaled
$16.2 million and was comprised primarily of $26.9 million of accounts
receivable, $9.4 million of property and equipment, $1.1 million of other assets
and $5.8 million in cash, offset by $27.0 million of assumed liabilities. The
excess of the purchase price over the net assets acquired was $73.4 million and
was allocated to goodwill. The total purchase price of $89.6 million was paid by
issuing $36.5 million of common stock (0.6 million shares) and notes and $53.1
million in cash. We also issued 207,171 shares of common stock with a value of
$15.8 million related to the payment of contingent consideration from earlier
acquisitions. Of the $15.8 million, $0.2 million was recorded as a reduction of
other current liabilities and $15.6 million as additional goodwill.
Additionally, $8.0 million of contingent consideration was paid in cash and was
recorded as goodwill.




The accompanying notes are an integral part of these consolidated financial
statements.






Note 1 - Nature of the Business and Summary of Significant Accounting Policies

We are a leading end-to-end voice, video, data and energy network
infrastructure solution for a broad range of communications, broadband, energy
and other corporate clients. We have a diverse client base representing all the
major segments of the industries we serve. Our broad suite of services allows
our clients to connect with their customers. We design, build, install, maintain
and monitor internal and external networks, transmission facilities and data
storage centers supporting e-commerce and other communications, computing and
energy systems. We are a national services provider, operating from 200 service
locations throughout the United States and Canada. We also operate in Brazil
through a 51% owned joint venture.

Revenue generated by North American operations, as a percentage of total
revenue, was 63.8%, 94.8% and 95.8% in 1998, 1999 and 2000, respectively. For
the years ended December 31, 1998, 1999 and 2000, revenue expressed as a
percentage of North American revenue generated by datacom network services was
81.5%, 84.6% and 88.8%, respectively, and by energy network services was 18.0%,
15.3% and 11.2%, respectively. See Note 10. For 1999 and 2000, international
operations consisted primarily of our operations in Brazil. In 1998,
international operations included our Spanish operations. Effective December 31,
1998, we sold 87% of our Spanish operations.

A summary of the significant accounting policies followed in the
preparation of the accompanying consolidated financial statements is presented
below:

Management's estimates. The preparation of financial statements in
conformity with generally accepted accounting principles requires us 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. The more significant estimates relate to our
allowance for doubtful accounts, accrued insurance and the realization of
certain intangibles. Actual results could differ from those estimates.

Principles of consolidation. The consolidated financial statements include
MasTec, Inc. and its subsidiaries including our 51% interest in our Brazilian
operations. All material intercompany accounts and transactions have been
eliminated. Certain prior year amounts have been reclassified to conform to the
current year presentation.

Comprehensive income (loss). As reflected in the consolidated statement of
changes in shareholders' equity, comprehensive income is a measure of net income
and all other changes in equity that result from transactions other than with
shareholders. Comprehensive income (loss) consists of net income (loss) and
foreign currency translation adjustments.

Foreign currency. We operate in Brazil, which is subject to greater
political, monetary, economic and regulatory risks than our domestic operations.
During January 1999, the Brazilian government allowed its currency to trade
freely against other currencies resulting in an immediate devaluation of the
Brazilian real. Assets and liabilities of foreign subsidiaries and equity with a
functional currency other than U.S. dollars are translated into U.S. dollars at
exchange rates in effect at the end of the reporting period. Foreign entity
revenue and expenses are translated into U.S. dollars at the average rates that
prevailed during the period. The resulting net translation gains and losses are
reported as foreign currency translation adjustments in shareholders' equity as
a component of other accumulated comprehensive income. Exchange gains and losses
on transactions and equity investments denominated in a currency other than
their functional currency are included in results of operations as incurred.

Revenue recognition. Revenue and related costs for short-term construction
projects (i.e., generally projects with a duration of less than one month) are
recognized as the services are rendered. 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 ratio of estimated cost incurred
to total estimated contract cost. Monitoring service and support revenue is
recognized ratably over the term of the agreement. We also provide management,
coordination, consulting and administration services for network infrastructure
projects. Compensation for such services is recognized ratably over the term of
the service agreement.




Note 1 - Nature of the Business and Summary of Significant Accounting Policies
(cont'd)

Losses, if any, on 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. Work in process on contracts is based on work
performed but not billed to clients as per individual contract terms.

Earnings per share. Basic earnings per common share is computed by dividing
income available to common shareholders by the weighted average number of common
shares outstanding. Diluted earnings per common share include the dilutive
effect of stock options using the treasury stock method. The difference between
the weighted average common shares outstanding used to calculate basic and
diluted earnings per share relates to stock options assumed exercised under the
treasury method of accounting of approximately 910,000 and 1,984,000 at December
31, 1999 and 2000, respectively. Included in the diluted earnings per share
computation are approximately 167,000 shares for the year ended December 31,
2000, to be issued in connection with an acquisition of a datacom network
service provider. Potentially dilutive shares as of December 31, 1998 totaling
504,000 shares were not included in the diluted per share calculation because
their effect would be anti-dilutive as we incurred a loss that year.
Accordingly, for 1998, diluted net loss per common share is the same as basic
net loss per common share.

Cash and cash equivalent. We consider all short-term investments with
maturities of three months or less when purchased to be cash equivalents. At
December 31, 1999 and 2000, we had cash and cash equivalent denominated in
Brazilian reals that translate to approximately $20.5 million and $6.0 million,
respectively.

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

Property and equipment. Property and equipment are recorded at cost.
Depreciation and amortization are computed using the straight-line method over
the estimated useful lives of the respective assets. 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 other income.

Intangibles and other long lived assets. Assets and liabilities acquired in
connection with business combinations accounted for under the purchase method
are recorded at their respective estimated fair values. Goodwill represents the
excess of the purchase price over the estimated fair value of net assets
acquired, including the recognition of applicable deferred taxes, and is
amortized on a straight-line basis over a period ranging from 5 to 40 years,
with a weighted average amortization period of 33 years. At December 31, 1999
and 2000, we had recorded intangibles primarily consisting of goodwill of $151.6
million and $262.4 million, respectively (net of accumulated amortization of
$24.5 million in 1999 and $35.5 million in 2000). For the year ended December
31, 1999 and 2000, we had goodwill deductible for tax purposes of $5.8 million
and $6.8 million, respectively. As of December 31, 2000, we reflected in other
current liabilities $35.0 million of contingent consideration expected to be
paid during the first six months of 2001.

We review long-lived assets, identifiable intangibles and goodwill and
record an impairment whenever events or changes in circumstances indicate that
the carrying amount of the assets may not be fully recoverable. Recoverability
of assets to be held and used is measured by a comparison of the carrying amount
of the assets to future undiscounted net cash flows expected to be generated by
the assets. If such assets are considered to be impaired, the impairment to be
recognized is measured by the amount by which the carrying amount of the assets
exceeds the fair value of the assets or expected future cash flows on an
undiscounted basis. Assets to be disposed of are reported at the lower of the
carrying amount or fair value less costs to sell.



Note 1 - Nature of the Business and Summary of Significant Accounting Policies
(cont'd)

Accrued insurance. We maintain insurance policies subject to deductibles of
$250,000 per occurrence for certain property and casualty and worker's
compensation claims and, accordingly, accrue the estimated losses. For the year
ended December 31, 2000, we have an aggregate stop loss coverage of $16.1
million adjusted for certain exposures.

Income taxes. We record income taxes using the liability method of
accounting for deferred income taxes. Under this method, deferred tax assets and
liabilities are recognized for the expected future tax consequence of temporary
differences between the financial statement and income tax bases of our assets
and liabilities. A valuation allowance is established when it is more likely
than not that any or all of the deferred tax assets will not be realized.

Stock based compensation. We adopted the disclosure provision of Statement
of Financial Accounting Standard No. 123, Accounting for Stock Based
Compensation ("SFAS 123") and retained the intrinsic value method of accounting
for such stock based compensation (see Note 7).

Fair value of financial instruments. We estimate the fair market value of
financial instruments through the use of public market prices, quotes from
financial institutions and other available information. Judgment is required in
interpreting data to develop estimates of market value and, accordingly, amounts
are not necessarily indicative of the amounts that we could realize in a current
market exchange. Our short-term financial instruments, including cash and cash
equivalents, accounts and notes receivable, accounts payable and other
liabilities, consist primarily of instruments without extended maturities, the
fair value of which, based on management's estimates, equaled their carrying
values. Long-term debt is carried at face value less unamortized discount. The
fair value of our 7.75% senior subordinated notes was approximately $188.0
million at December 31, 2000. We use 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
marketplace.

New pronouncements. In December 1999, the Securities and Exchange
Commission ("SEC") issued Staff Accounting Bulletin No. 101 "Revenue
Recognition" ("SAB 101"), which provides guidance on the recognition,
presentation and disclosure of revenue in financial statements filed with the
SEC. SAB 101 is applicable beginning with our fourth quarter 2000 consolidated
financial statements. The application of SAB 101 did not have a material impact
on our financial results. In June 1998, the Financial Accounting Standards Board
(the "FASB") issued SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities." SFAS No. 133 requires a company to recognize all derivative
instruments (including certain derivative instruments embedded in other
contracts) as assets or liabilities in its balance sheet and measure them at
fair value. The statement requires that changes in the derivative's fair value
be recognized currently in earnings unless specific hedge accounting criteria
are met. In June 1999, SFAS No. 137, "Deferral of the Effective Date of FASB
Statement No. 133," was issued and defers the adoption date to the beginning of
an entity's fiscal year-end beginning after June 15, 2000. We do not believe
that the adoption of this statement will have a material impact on our financial
position or results of operations.

Note 1 - Nature of the Business and Summary of Significant Accounting Policies
(cont'd)

Stock split. On June 19, 2000, we effected a three-for-two split of our
common stock in the form of a stock dividend to shareholders of record as of May
29, 2000. To reflect the split, common stock was increased and capital surplus
was decreased by $1.6 million. All references in the consolidated financial
statements to shares and related prices, weighted average number of shares, per
share amounts and stock plan data have been adjusted to reflect the stock split
on a retroactive basis.

Warranty costs. For certain contracts, we warrant labor for new
installations and construction and servicing of existing infrastructure. An
accrual for warranty costs is recorded based upon the historical level of
warranty claims and management's estimate of future costs.

Note 2 - Investing Activities

Since 1999, we have completed 16 acquisitions, all in our datacom network
services group. These acquisitions have been accounted for under the purchase
method of accounting. Accordingly, the results of operations of acquired
companies have been included in our consolidated results of operations from
their respective acquisition dates. If the acquisitions had been made at the
beginning of 1999 or 2000, pro forma results of operations would not have
differed materially from actual results based on historical performance prior to
their acquisition by us. The most significant adjustments to the balance sheet
resulting from these acquisitions are disclosed in the supplemental disclosure
of non-cash investing and financing activities in the accompanying statement of
cash flows. Common stock issued in acquisitions is valued based upon the market
price of the common stock around the date of purchase or the date the purchase
price is determined. Acquisition agreements may include provisions for
contingent payments, depending on future performance. As future performance
goals are met, goodwill is adjusted for the amount of such payments.

From time to time we may invest in our clients or receive securities to
purchase shares in our clients for nominal prices. As of December 31, 2000, we
had recorded approximately $13.0 million related to such investments.

Note 3 - Accounts Receivable

Accounts receivable are presented net of an allowance for doubtful accounts
of $7.3 million, $9.7 million, and $11.0 million at December 31, 1998, 1999 and
2000, respectively. We recorded a provision for doubtful accounts of $4.5
million, $4.7 million and $6.6 million during 1998, 1999 and 2000, respectively.
In addition, we recorded write-offs of $0.3 million, $2.3 million and $5.3
million during 1998, 1999 and 2000, respectively.

Accounts receivable includes retainage which has been billed but is not due
until completion of performance and acceptance by clients, and claims for
additional work performed outside original contract terms. Retainage aggregated
$16.5 million and $24.6 million at December 31, 1999 and 2000, respectively.
Retainage is expected to be collected within one year. Any retainage expected to
be collected beyond a year is recorded in long-term other assets.

Included in accounts receivable is unbilled revenue of $69.6 million and
$98.8 million at December 31, 1999 and 2000, respectively. Such unbilled amounts
represent work performed but not billable to clients as per individual contract
terms, of which $18.6 million and $23.2 million at December 31, 1999 and 2000,
respectively, are related to our Brazilian operations. Unbilled revenue is
typically billed within one to two months.

From time to time, in exchange for one or more of long-term exclusive
infrastructure services agreements, interest, financing and other fees, and
warrants or other equity interests in the client, we may grant payment terms
typically for six to eighteen months to our clients.At December 31, 2000, we had
$31.5 million under these arrangements.



Note 4 - Property and Equipment

Note 5 - Debt (cont'd)

We have a credit facility that provides for borrowings up to an aggregate
of $100 million. Amounts outstanding under the revolving credit facility mature
on June 9, 2002. We are required to pay an unused facility fee ranging from .25%
to .50% per annum on the facility, depending upon certain financial covenants.
The credit facility is secured by a pledge of shares of certain of our
subsidiaries. Interest under the credit facility accrues at rates based, at our
option, on the agent bank's base rate plus a margin of up to .50% depending on
certain financial covenants or 1% above the overnight federal funds effective
rate, whichever is higher, or its LIBOR Rate (as defined in the credit facility)
plus a margin of 1.00% to 2.25%, depending on certain financial covenants. As of
December 31, 2000, we had outstanding $8.4 million in standby letters of credit.

The credit facility and the senior subordinated notes contain customary
events of default and covenants which prohibit, among other things, making
investments in excess of a specified amount, incurring additional indebtedness
in excess of a specified amount, paying dividends in excess of a specified
amount, making capital expenditures in excess of a specified amount, creating
liens, prepaying other indebtedness, including the senior notes, and engaging in
certain mergers or combinations without the prior written consent of the
lenders. The credit facility also provides that we must maintain certain
financial ratio coverages, requiring, among other things minimum ratios at the
end of each fiscal quarter of debt to earnings and earnings to interest expense.

At December 31, 2000, debt matures as follows:



2001 ................................. $ 5,684
2002 ................................. 10,068
2003 ................................. 188
2004.................................. 100

Note 6 - Lease Commitments

We have operating lease agreements for our premises and equipment that
expire on various dates. The operating lease agreements are subject to
escalation. Rent expense for the years ended December 31, 1999 and 2000 was
approximately $14.8 million and $14.4 million, respectively.

Minimum future lease commitments under non-cancelable operating leases in
effect at December 31, 2000 were as follows:



2001.................................... $ 15,928

Note 7 - Retirement and Stock Option Plans

We have a 401(k) plan covering all eligible employees. Subject to certain
dollar limits, eligible employees may contribute up to 15% of their pre-tax
annual compensation to the plan. We match in stock 50% of the employee
contributions up to 4% of their gross salary and may make discretionary
contributions in amounts determined by the Board of Directors. Prior to January
1, 2000, our match was 25% of the employee contributions up to 4% of their gross
salary. Our matching contributions charged to earnings were approximately
$186,000, $547,000 and $2,077,000 for the years ended December 31, 1998, 1999
and 2000, respectively.

We have three stock option plans currently in effect: the 1994 Stock
Incentive Plan (the "1994 Plan"), the 1994 Stock Option Plan for Non-Employee
Directors (the "Directors' Plan") and the 1999 Non-Qualified Employee Stock
Option Plan (the "Non-Qualified Plan"). Typically, options under these plans are
granted at fair market value at the date of grant, vest between three to five
years and terminate no later than 10 years from the date of grant.

Under these plans there were a total of 1,937,943, 1,030,055 and 2,028,798
options available for grant at December 31, 1998, 1999 and 2000, respectively.
We also have a non-qualified stock purchase plan under which eligible employees
may purchase common stock through payroll deductions or in a lump sum at a 15%
discount from fair market value. In addition, there are 292,100 options
outstanding under individual option agreements with varying vesting schedules at
exercise prices ranging from $2.56 to $17.67 with terms up to 10 years.

The following is a summary of all stock option transactions:

We have elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations in
accounting for our employees' stock options. Pursuant to APB No. 25, no
compensation cost has been recognized.

We have reflected below the 1998, 1999 and 2000 earnings as if compensation
expense relative to the fair value of the options granted had been recorded
under the provisions of SFAS No. 123 "Accounting for Stock- Based Compensation."
The fair value of each option grant was estimated using the BlackScholes
option-pricing model with the following assumptions used for grants in 1998,
1999 and 2000, respectively: a six, five and five year expected life; volatility
factors of 72%, 41% and 60%; risk-free interest rates of 4.3%, 5.9% and 5.75%;
and no dividend payments.

The net deferred tax liability includes deferred items resulting from
acquisitions made during the period which are not reflected as part of the
deferred tax provision. Certain of the acquired entities were S corporations for
income tax purposes and, accordingly, any income tax liabilities for the periods
prior to the acquisitions are the responsibility of the respective shareholders.

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

During 1998, we sold 87% of our Spanish operations which resulted in a tax
liability of $7.8 million.

The Internal Revenue Service ("IRS") examined our federal income tax
returns for the years ended December 31, 1995 and 1996. The IRS has agreed not
to audit the year ended December 31, 1997. Assessments made for the years 1995
through 1997 are presently being negotiated at the appellate level. We believe
we have legal defenses to reduce the proposed deficiency, although there can be
no assurance in this regard. We believe that the ultimate disposition of this
matter will not have a material adverse effect on our consolidated financial
statements.

Note 9 - Capital Stock

We have authorized 100,000,000 shares of common stock, $0.10 par value. At
December 31, 1999 and 2000, approximately 42,350,000 shares and 47,702,000
shares, respectively, of common stock were issued and outstanding. At December
31, 1999 and 2000, we had 5,000,000 shares of authorized but unissued preferred
stock.



Note 10 - Operations by Geographic Areas and Segments

For the year ended December 31, 2000, approximately 7% of our revenue was
derived from services performed for BellSouth. For the year ended December 31,
1999, approximately 12.0% of our revenue was derived from services performed for
BellSouth.

Our operations consist of four segments: datacom network services, energy
network services, international and other.

Datacom Network Services. We design, build, install, maintain and monitor
the physical facilities used to provide end-to-end telecommunications service
from the provider's central office, switching center or cable television
head-end to the ultimate consumer's home or business. We provide these services
both externally on public or private rights-of-ways or in our clients' premises.

Energy Network Services. We provide external network and infrastructure
services to public and private utilities. These services consist of overhead and
underground installation and maintenance of electrical and other utilities'
transmission and distribution networks, substation construction and maintenance,
right-of-way maintenance and restoration of asphalt and concrete surfaces. These
services are substantially similar to the services we provide to our
telecommunications clients, but the work often involves the installation and
splicing of high-voltage transmission and distribution lines.

International. We operate in Brazil through a 51% joint venture which we
consolidate net of a 49% minority interest after tax. Our Brazilian operations
provide datacom infrastructure services to a diverse group of telecommunication
companies primarily in the heavily populated states of southern Brazil.

The following table sets forth, for each of 1998, 1999 and 2000, certain
information about segment results of operations and segment assets (in
thousands).

(1) Revenue, amortization and capital expenditures relate solely to our
Brazilian operations for 1999 and 2000, and include Spanish and Brazilian
operations for 1998. International income before provision for income taxes
and minority interest for the year ended December 31, 2000, primarily
relates to the sale of our PCS system net of a charge for the write-off of
two Latin American operations and write-down of non-core assets. For the
other periods, income was related solely to our Brazilian operations in
1999 and included our Brazilian and Spanish operations in 1998. Total
assets includes $118.2 million, $89.7 million and $50.8 million as of
December 31, 1998, 1999 and 2000, respectively, related to our Brazilian
operations, and the remainder relates to our interest in international
non-core assets.
(2) Consists of non-core construction and corporate operations, which includes
interest expense net of interest income of $18.0 million, $20.1 million and
$14.3 million for the years ended December 31, 1998, 1999 and 2000,
respectively. Additionally, charges of $34.0 million in 1998, $10.2 million
in 1999, and $26.3 million in 2000 are also reflected.




Note 10 - Operations by Geographic Areas and Segments (cont'd)

There are no significant transfers between geographic areas and segments.
Total assets are those assets used in our operations in each segment. Corporate
assets include cash and cash equivalents, non-core assets held for sale and
notes receivable.

Note 11 - Commitments and Contingencies

We have filed lawsuits in Florida state court against a subsidiary of
Artcom Technologies, Inc., a holding company for a Spanish infrastructure
provider that we formerly owned, to recover more than $5.0 million due under a
promissory note and for breach of contract. We are also pursuing other claims
against Artcom affiliates totalling approximately $4.0 million. Artcom has
responded by suing us in federal court in Florida to recover approximately $6.0
million (subject to trebling) it alleges we received as a result of certain
allegedly unauthorized transactions by two former employees of Artcom that
occurred after we sold the company.

In January 2001, we filed suit in Florida state court against Broward
County, Florida, to recover approximately $5.0 million for work performed to
construct a detention facility for the Broward Sheriff's Office ("BSO"). The BSO
has filed a separate lawsuit in response to our lawsuit claiming $13.0 million
in damages for alleged delays in constructing the facility.

In November 1997, we filed a suit against Miami-Dade County in Florida
state court alleging breach of contract and seeking damages exceeding $3.0
million in connection with the county's refusal to pay amounts due to us under a
multi-year agreement to perform road restoration work for the Miami-Dade Water
and Sewer Department ("MWSD"), a department of the county. The county has
counterclaimed against us seeking unspecified damages.

We are a party to other pending legal proceedings arising in the normal
course of business, none of which we believe is material to our financial
position or results of operations.

In connection with certain contracts, we have signed certain agreements of
indemnity in the aggregate amount of approximately $500.0 million, of which
approximately $338.5 million relate to the uncompleted portion of contracts in
process as of December 31, 2000. These agreements are to secure the fulfillment
of obligations and performance of the related contracts.



Our operations in Brazil are 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. We 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 our Brazilian operations.

Note 12 - Other Expense, net

For the year ended December 31, 1999 other expense, net consists of a $33.8
million charge related to up-front payments pursuant to employment and
non-competition agreements entered into with managers at two of our datacom
units. The up-front payments were paid to resolve issues arising from the
original price paid for the acquisition of their businesses and were not
attributed to future services nor contemplated, included or required under the
original terms of the related acquisition agreements. In addition, other
expense, net also included a loss of $9.2 million on the sale of our Spanish
operations offset by other income of approximately $4.1 million primarily
related to our Spanish operations.

For the year ended December 31, 1999, other expense, net primarily includes
a write-down, based on the results of an analysis performed by management on the
carrying value of certain of our international non-core assets, of $10.2
million, a $3.6 million loss on the sale of a non-core business and parcels of
non-core real estate, $1 million litigation reserve for a 1994 lawsuit from a
predecessor company offset by other income of $4.8 million from a customer
related to extensions to the maturity date of a vendor financing agreement.

For the year ended December 31, 2000 other expense, net is comprised
primarily of a $28.9 million write-down of certain non-core international assets
resulting from management's review of the carrying value of such assets, $7.0
million for severance and litigation accruals offset by a $9.6 million gain on
the sale of our PCS system in Latin America.


Note 13 - Quarterly Information (Unaudited)

The following table presents unaudited quarterly operating results for
the two years ended December 31, 2000. We believe that all necessary adjustments
have been included in the amounts stated below to present fairly the quarterly
results when read in conjunction with the Consolidated Financial Statements and
Notes thereto for the years ended December 31, 1999 and 2000.

non-core assets net of tax or $0.14 per share.

In the second quarter of 2000, we recorded a net gain of $2.5 million from
the sale and write-down of a non-core asset net of tax or $0.05 per share.

In the third quarter of 2000, we recorded a severance charge of $1.0
million net of tax or $0.02 per share.

In the fourth quarter of 2000, we recorded a $17.3 million charge primarily

Exhibit 10.12


MASTEC, INC.


2000 Chief Executive Officer Incentive Compensation Plan

The 2000 Chief Executive Officer Incentive Compensation Plan provides an
Incentive Award for MasTec, Inc.'s Chief Executive Officer based upon
performance during the Performance Period (as defined below). Performance is
evaluated using the criteria of earnings before interest and taxes (EBIT), as
defined under generally accepted accounting principles consistently applied on a
consolidated basis by MasTec. To be eligible for an Incentive Award, MasTec must
meet at least a minimum EBIT and ROA, as described below.

Performance Period

The Performance Period under this Plan begins January 1, 2000 and ends
December 31, 2000.

Incentive Award

The Chief Executive Officer's 2000 Incentive Award will be calculated based
on budgeted EBIT for 2000 from North American operations only ("Budgeted EBIT").
The Chief Executive Officer will not be entitled to an Incentive Award unless
EBIT from North American operations is at least 97% of Budgeted EBIT ("Minimum
EBIT"). If the Minimum EBIT is achieved in 2000, the Chief Executive Officer
will be entitled to the following bonus:

o If EBIT is equal to or more than the Minimum EBIT but less than 103%
of Budgeted EBIT, the Chief Executive Officer will be entitled to an
Incentive Award equal to 0.75% of actual EBIT from North American
operations for 2000.

o If EBIT is equal to 103% of Budgeted EBIT or more but less than 112%
of Budgeted EBIT, the Chief Executive Officer will be entitled to an
Incentive Award equal to 1.00% of actual EBIT from North American
operations for 2000.

o If EBIT is equal to 112% of Budgeted EBIT or more, the Chief Executive
Officer will be entitled to an Incentive Award equal to 1.25% of
actual EBIT from North American operations for 2000.

After the close of the Performance Period, the Compensation Committee will
determine whether the performance goals have been met based on MasTec's results
for the year. If the performance goals have been met, the Chief Executive
Officer becomes eligible for Incentive Awards as specified in the Plan. The
final Incentive Award must be approved by the Compensation Committee of MasTec's
Board of Directors. The Compensation Committee reserves the right to make
adjustments in Incentive Awards based on extenuating circumstances.



Payment of Awards

Approved Incentive Awards will be paid no later than March 31, 2001.
Incentive Awards will be paid in cash, MasTec common stock, options to purchase
MasTec common stock, or any combination of cash, stock or options, as determined
by the Compensation Committee, except that not less than 50% of the Incentive
Award will be paid in cash. The common stock portion of an Incentive Award may
be restricted from sale or other transfer for such period of time as the
Compensation Committee may determine, not to exceed one (1) year from the date
of award.

All stock options awarded as part of an Incentive Award will be options to
purchase MasTec common stock at an exercise price equal to the fair market value
of the common stock on a date or dates to be determined by the Compensation
Committee, will have a term of not less than seven (7) years, and will vest in
accordance with a vesting schedule to be determined by the Compensation
Committee, not to exceed three (3) years from the date of grant. All common
stock and stock options awarded under the Plan will be issued pursuant to the
MasTec 1994 Stock Incentive Plan or the 1999 Non-Qualified Employee Stock Option
Plan, as in effect on the date of award. Nothing in this Plan will prevent
MasTec from amending the Stock Incentive Plan or the Non-Qualified Stock Option
Plan in its sole discretion.

Employment Termination

If the Chief Executive Officer's employment with the Company or any of its
affiliates terminates prior to December 31, 2000 for "Cause," the Chief
Executive Officer will lose all rights and benefits under the Plan and will not
be entitled to any Incentive Award, any restricted stock granted under the Plan
will be forfeited as of the effective date of termination of employment, and any
unvested stock options granted under the Plan will terminate as of the effective
date of the termination of employment. If the employment of the Chief Executive
Officer with the Company or any of its affiliates terminates prior to December
31, 2000 for any other reason (including termination without "Cause," death or
Disability, as defined in the Plan), then the Chief Executive Officer will not
be entitled to an Incentive Award under this Plan but will receive the bonus
described in the Chief Executive Officer's employment agreement with the
Company. In addition, if the Chief Executive Officer's employment is terminated
without Cause, any restricted common stock portion of an Incentive Award will be
free of any restriction and the vesting of any outstanding stock options granted
under this Plan will be accelerated to the effective date of termination and may
be exercised by the Chief Executive Officer for the full term of the options.




"Cause" for purposes of the Plan means (i) the Chief Executive Officer
being convicted of any felony (whether or not against the Company or its
affiliates), (ii) willful malfeasance in the performance of the Chief Executive
Officer's responsibilities after ten (10) days' written notice to the Chief
Executive Officer and an opportunity to cure; (iii) any material act of
dishonesty by the Chief Executive Officer against the Company or any of its
affiliates, (v) a material violation by the Chief Executive Officer of any of
the policies or rules of the Company or any of its affiliates or (vi) the
voluntary resignation of the Chief Executive Officer from employment with the
Company or any of its affiliates. The determination that Cause has occurred must
be made by unanimous vote of all the members of the Board of Directors of the
Company after forty five (45) days' prior written notice to the Chief Executive
Officer and an opportunity to appear before the Board and contest the
determination of Cause.

"Disability" means the inability to perform the material duties of the
Chief Executive Officer.

Change in Control

In the event of a Change in Control of the Company, the employment of the
Chief Executive Officer will be deemed terminated without "Cause" for purposes
of the Plan. A "Change in Control of the Company" means the occurrence of any of
the following events:

(a) any consolidation or merger of MasTec in which MasTec is not the
continuing or surviving corporation or pursuant to which shares of
Common Stock are to be converted into cash, securities or other
property, provided that the consolidation or merger is not with a
corporation which was a wholly-owned subsidiary of MasTec immediately
before the consolidation or merger; or

(b) any sale, lease, exchange or other transfer (in one transaction or a
series of related transactions) of all, or substantially all, of the
assets of MasTec; or

(c) the shareholders of MasTec approve any plan or proposal for the
liquidation or dissolution of MasTec; or

(d) any "person," including a "group" as determined in accordance with
Sections 13(d) and 14(d) of the Exchange Act, becomes the beneficial
owner (within the meaning of Rule 13d-3 under the Exchange Act),
directly or indirectly, of 33% or more of the combined voting power of
MasTec's then outstanding Common Stock, provided that such person,
immediately before it becomes such 33% beneficial owner, is not (i) a
wholly-owned subsidiary of MasTec, (ii) an individual, or a spouse or
a child of such individual, that on January 1, 2000, owned greater
than 20% of the combined voting power of such Common Stock, or (iii) a
trust, foundation or other entity controlled by an individual or
individuals described in the preceding subsection; or




(e) individuals who constitute the Board on January 1, 2000 (the
"Incumbent Board"), cease for any reason to constitute at least a
majority thereof, provided that any person becoming a director
subsequent to January 1, 2000, whose election, or nomination for
election by MasTec's shareholders, was approved by a vote of at least
three quarters of the directors comprising the Incumbent Board (either
by a specific vote or by approval of the proxy statement of MasTec in
which such person is named as a nominee for director, without
objection to such nomination) will be, for purposes of this clause,
considered as though such Person were a member of the Incumbent Board.

Notwithstanding the foregoing, Incumbent Directors may, by a two-thirds
vote of such Directors, declare a given transaction will not constitute a Change
in Control for purposes of the Plan.

Award Non-Transferability

No Incentive Award under the Plan, and no rights or interests herein, are
assignable or transferable by a Chief Executive Officer except by will or the
laws of descent and distribution, subject to the other provisions of the Plan.
During the lifetime of a Chief Executive Officer, Incentive Awards will be paid
only to the Chief Executive Officer or his or her legal representative.

Administration

The Compensation Committee will administer the Plan. The Compensation
Committee is authorized to construe and interpret the Plan, to promulgate, amend
or rescind rules and regulations relating to the implementation of the Plan and
to make all other determinations necessary or advisable for the administration
of the Plan. The Compensation Committee may designate persons other than members
of the Compensation Committee to carry out its responsibilities under such
conditions and limitations as it may prescribe. Any determination, decision or
action of the Compensation Committee in connection with the construction,
interpretation, administration, or application of the Plan will be final,
conclusive and binding upon all Chief Executive Officers.

Amendment and Termination

The MasTec Board of Directors, in its sole discretion, may at any time
terminate the Plan, or from time to time may amend it in such respects as it
deems appropriate.

Tax Withholding

Subject to Section 83 of the Internal Revenue Code, the Company will deduct
from any Incentive Award any federal, state or local taxes of any kind required
by law to be withheld with respect to such payments or to take such other action
as may be necessary in the opinion of the Company to satisfy all obligations of
the payment of such taxes.




Plan Funding

The Plan will be unfunded and the Company will not be required to segregate
any assets that may at any time be represented by Incentive Awards under the
Plan. Any liability of the Company to any person with respect to any Incentive
Award under the Plan will be based solely upon any contractual obligations that
may be effected pursuant to the Plan. No such obligation of the Company will be
secured by any pledge of, or other encumbrance on, any property of the Company.

Other Company Benefit and Compensation Programs

Payments and other benefits received by the Chief Executive Officer
pursuant to the Plan will not be deemed part of the Chief Executive Officer's
regular and recurring compensation for purposes of the termination indemnity or
severance pay law of any jurisdiction and will not be included in nor have any
effect on, the determination of benefits under any other employee benefit plan
or similar arrangements provided by the Company.

Plan Costs

The costs and expenses of administering the Plan will be borne by the
Company.

Governing Law

The Plan and all actions taken thereunder will be interpreted under and
governed by the laws of the State of Florida, without regard to its conflict of
laws rules.

Effective Date

The Plan will be effective when approved by the Compensation Committee.

Definitions

As used in the Plan, the terms below have the following meanings:

"MasTec" or the "Company" means MasTec, Inc., a Florida corporation, or any
successor company or subsidiary company designated by the Board of Directors of
