                                    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

   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.

Sabater  was our  Controller.  Prior to  joining  us, Ms.  Sabater  was a Senior
Manager with Deloitte & Touche, a public accounting firm.

     Jose Sariego has been our Senior Vice  President and General  Counsel since
September 1995.  Prior to joining us, Mr. Sariego was Senior  Corporate  Counsel
and Secretary of Telemundo Group, Inc., a Spanish language  television  network,
from August 1994 to August 1995.  From January 1990 to August 1994,  Mr. Sariego
was a partner in the Miami office of Kelley Drye & Warren,  an international law
firm.

     Arlene Vargas has been our Vice  President and Controller  since  September

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.

     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."

     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

     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

     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.

     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.

     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.

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.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To  the Board of Directors and Shareholders of MasTec, Inc.:


In our opinion,  the  accompanying  consolidated  balance sheets and the related
consolidated statements of operations,  changes in shareholders' equity and cash
flows  present  fairly,  in all material  respects,  the  financial  position of
MasTec, Inc. and its subsidiaries at December 31, 1999 and 2000, and the results
of their  operations  and their  cash  flows for each of the three  years in the
period  ended  December  31,  2000  in  conformity  with  accounting  principles
generally accepted in the United States of America.  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 of these  statements in accordance with auditing  standards
generally  accepted in the United States of America,  which 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,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

                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.

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 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:

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

(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.

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

the sale and write-down of a non-core asset net of tax or $0.05 per share.

                          SIXTH AMENDMENT TO REVOLVING
                                CREDIT AGREEMENT

     THIS SIXTH AMENDMENT TO REVOLVING CREDIT AGREEMENT (this "Sixth Amendment")
is made and  entered  into as of the  11th day of  August,  1999,  by and  among
MASTEC, INC., a Florida corporation (the "Parent"), its Subsidiaries (other than

Revolving Credit Agreement dated as of January 28, 1998, as further amended by a

terms set forth therein;

     WHEREAS,   the  Parent  has  requested  certain  revisions  to  the  Credit
Agreement,  including an extension of the Maturity  Date, and the parties desire
to amend the Credit Agreement on the terms set forth herein;

     NOW, THEREFORE,  in consideration of the foregoing,  and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties agree to amend the Credit Agreement as follows:

     1.   Definitions.  Capitalized  terms used herein without  definition shall

          "Maturity Date. June 9, 2001; as the same may be extended  pursuant to
          ss.2.8, but which date shall in no event be later than June 9, 2002."

     3.   Amendment to ss.7.5 of the Credit Agreement. Section 7.5 of the Credit

          pages by 5:00 p.m.  Boston time on August 11, 1999 by facsimile (to be

          equal to 0.10% of such Bank's Commitment  payable to such Bank for its
          own account.

     5.   Effectiveness.  This Sixth Amendment shall become  effective as of the
          date  hereof,  subject to the  satisfaction  of each of the  following
          conditions:

          (a) The  execution,  delivery  and  performance  of each of this Sixth
          Amendment  and the  transactions  contemplated  hereby  are within the
          corporate  power and  authority of such Borrower and have been or will

          contravene  any provision of the charter  documents or by-laws of such
          Borrower or any law, rule or regulation  applicable to such  Borrower,

          or event which,  but for the requirement that time elapse or notice be
          given, or both,  would constitute an event of default under, any other
          material   agreement,   instrument  or  undertaking  binding  on  such
          Borrower.

          (b) This Sixth  Amendment and the Credit  Agreement,  as amended as of
          the date  hereof,  and all of the  terms  and  provisions  hereof  and
          thereof are the legal, valid and binding  obligations of such Borrower

          limited by bankruptcy, insolvency, reorganization, moratorium or other
          laws affecting the  enforcement of creditors'  rights  generally,  and
          except as the remedy of specific  performance or of injunctive  relief

                                  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.
