NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 1997


1.       CONSOLIDATION AND PRESENTATION

         The accompanying  unaudited condensed consolidated financial statements
of MasTec,  Inc.  ("MasTec" or the  "Company")  have been prepared in accordance
with generally accepted accounting  principles for interim financial information
and with the  instructions  for Form 10-Q and Rule 10-01 of Regulation S-X. They
do not  include  all  information  and  notes  required  by  generally  accepted
accounting  principles for complete  financial  statements and should be read in
conjunction with the audited financial  statements and notes thereto included in
the Company's  annual report on Form 10-K for the year ended  December 31, 1996.
The year end  condensed  balance  sheet data was derived from audited  financial
statements but does not include all disclosures  required by generally  accepted
accounting   principles.   The  financial  information  furnished  reflects  all
adjustments,  consisting  only of normal  recurring  accruals  which are, in the
opinion  of  management,  necessary  for a fair  presentation  of the  financial
position and results of  operations  for the periods  presented.  The results of
operations  are not  necessarily  indicative of future  results of operations or
financial position of MasTec.

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


2.       ACQUISITIONS

Domestic

         During  the six months  ended  June 30,  1997,  the  Company  completed
certain  acquisitions which have been accounted for under the purchase method of
accounting  and the  results of  operations  of which have been  included in the
Company's  condensed  consolidated  financial  statements  from  the  respective
acquisition dates. If the acquisitions had been made at the beginning of 1997 or
1996, pro forma results of operations  would not have differed  materially  from
actual results. Acquisitions made in 1997 were Kennedy Cable Construction,  Inc.
and Shanco  Corporation,  two contractors  servicing  multiple systems operators
such as MediaOne,  Time  Warner,  and Cox  Communications  in a number of states
including Alabama, Florida, Georgia, New Jersey, New York, North Carolina, South
Carolina and Texas;  R.D. Moody and Associates, Inc., B&D Contractors of Shelby,
Inc.,  Tele-Communications Corporation of Virginia, E.L. Dalton & Company, Inc.,
and R.D. Moody & Associates of Virginia, Inc., five telecommunications and 
utility   contractors   with  operations   primarily  in  the  southeastern  and
southwestern United States.

         Intangible  assets of approximately $20 million resulting from domestic
business acquisitions are included in other long term assets and principally  
consist of the  excess  acquisition  cost over the fair  value of the net assets
acquired (goodwill). Goodwill associated with domestic acquisitions is being
amortized on a  straight-ine  basis over a range of 15-20  years.  The  Company 
periodically reviews  goodwill to assess  recoverability.  See Note 3 for 
goodwill related to the Company's investment in unconsolidated companies.

         In  July  1997,  the  Company   completed  the   acquisition  of  Wilde
Construction, Inc. and two related companies that provide telecommunications and
cable television  infrastructure services in Minnesota,  North and South Dakota,
Iowa,  Nebraska and other  bordering  states.  The  acquisition  was  consumated
through a stock-for-stock  exchange that will be accounted for as a merger under
the pooling of interest method and accordingly  historical financial information
will be restated to reflect the merger as though it occurred January 1, 1995.





NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 1997


International

         On July 31,  1997,  the Company  completed  its  acquisition  of 51% of
MasTec-Inepar  S/A-Sistemas  de  Telecomunicacoes,   a  newly  formed  Brazilian
telecommunications  infrastructure  contractor  with a backlog of  approximately
$280 million in construction contracts in Brazil.

         On April 30, 1996,  the Company  purchased  from  Telefonica de Espana,
S.A.  ("Telefonica")  100% of the capital stock of Sistemas e  Instalaciones  de
Telecomunicacion,  S.A.  ("Sintel"),  a company  engaged  in  telecommunications
infrastructure  construction services in Spain, Argentina,  Chile, and Peru. The
Sintel acquisition gave the Company a significant  international  presence.  See
Note 5 regarding geographic information.

         The following  information  presents the unaudited pro forma  condensed
results of operations for the six months ended June 30, 1996 as if the Company's
acquisition of Sintel and certain related  transactions  had occurred on January
1, 1996. The Sintel  acquisition has been treated as a "purchase" as the term is
used under generally accepted accounting  principles.  Management's  preliminary
estimate of fair value approximated that of the carrying value of the net assets
acquired after  reflecting a reserve for employee  terminations  net of deferred
taxes.  The pro forma results,  which include  adjustments to increase  interest
expense  resulting  from the debt  incurred  pursuant to the Sintel  acquisition
($700,000),  offset by the  reduction  in  interest  and  depreciation  expenses
resulting from the related  transactions ($1.0 million) and a tax expense of 35%
is presented for informational  purposes only and is not necessarily  indicative
of the future results of operations or financial  position of the Company or the
results of  operations  or  financial  position  of the  Company  had the Sintel
acquisition and the related transactions occurred January 1, 1996.

                                          Pro forma results of operations
                                     for the six months ended June 30, 1996

Revenue                                             $ 254,876
Income from continuing operations                   $  13,264
Net income                                          $  13,277
Earnings per share:
Continuing operations                               $    0.54
Discontinued operations                                  0.00
Net income                                          $    0.54


         The pro forma  results for the six months  ended June 30, 1996  include
special  charges  incurred  by Sintel  related to a  restructuring  plan of $1.4
million, net of tax.

3.       INVESTMENTS IN UNCONSOLIDATED COMPANIES

         In July 1995, the Company made a $25 million one year non-recourse term
loan to Devono Company Limited, a British Virgin Islands corporation ("Devono").
The loan was  collateralized  by 40% of the capital  stock of a holding  company
that  owns   52.6%  of  the   capital   stock  of   Consorcio   Ecuatoriano   de
Telecomunicaciones,  S.A.  ("Conecell"),  one of two cellular phone operators in
the  Republic  of Ecuador.  In June 1997,  the  Company  converted  its loan and
accrued  interest  into the stock of the  holding  company  and  accordingly  is
reflecting  its investment as an investment in  unconsolidated  companies in the
accompanying June 30, 1997 consolidated balance sheet.

         Goodwill related to the Company's investments in unconsolidated 
companies amounted to $ 38.3 million at June 30, 1997 and is being amortized 
over a period of 17-20 years.

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

         The Company also has several credit facilities  denominated in Pesetas,
one  of  which  is a  revolving  credit  facility  with a  wholly-owned  finance
subsidiary of  Telefonica.  Interest on this  facility  accrues at MIBOR (Madrid
interbank  offered  rate) plus .30%.  At June 30,  1997,  the  Company had $45.8
million (6.8 billion  Pesetas) of debt  denominated in Pesetas,  including $24.4
million  remaining of the  acquisition  debt  incurred as a result of the Sintel
acquisition (see Note 2).

         Debt  agreements  contain,  among  other  things,  restrictions  on the
payment of dividends and require the observance of certain financial covenants.

5.       OPERATIONS BY GEOGRAPHIC AREAS

         The  Company's   principal  source  of  revenue  is  the  provision  of
telecommunications infrastructure construction services in the United States and
Spain.  Significant  international  operations commenced on May 1, 1996 with the
acquisition of Sintel (see Note 2).

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


6.       SIGNIFICANT CUSTOMERS AND CONCENTRATION OF CREDIT RISK

         The  Company  derives a  substantial  portion of its  revenue  from the
provision of  telecommunications  infrastructure  services to Telefonica  and to
BellSouth Telecommunications,  Inc. ("BellSouth"). For the six months ended June
30, 1997,  approximately  35.9% and 14.3% of the  Company's  revenue was derived
from services performed for Telefonica and BellSouth,  respectively. For the six
months ended June 30, 1996, the Company derived approximately 22% and 20% of its
revenue from services  performed for  Telefonica  and  BellSouth,  respectively.
Although the Company's strategic plan envisions  diversification of its customer
base,  the  Company  anticipates  that  it  will  continue  to be  dependent  on
Telefonica  and its  affiliates  and BellSouth for a significant  portion of its
revenue in the future.


7.       COMMITMENTS AND CONTINGENCIES

In  December  1990,  Albert H.  Kahn,  a  stockholder  of the  Company,  filed a
purported  class action and derivative  suit in Delaware state court against the
Company,  the  then-members  of its Board of  Directors,  and National  Beverage
Corporation  ("NBC"),  the  Company's  then-largest  stockholder.  The complaint
alleges,  among other  things,  that the  Company's  Board of Directors  and NBC
breached their respective fiduciary duties in approving certain transactions,




NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 1997


including the  distribution in 1989 to the Company's  stockholders of all of the
common  stock of NBC owned by the Company  and the  exchange by NBC of shares of
common stock of the Company for certain  indebtedness of NBC to the Company. The
lawsuit  seeks to  rescind  these  transactions  and to  recover  damages  in an
unspecified amount.

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

         Each of the  foregoing  lawsuits  is pending and no trial date has been
set.  The Company  believes  that the  allegations  in each of the  lawsuits are
without merit and intends to defend these lawsuits vigorously.

         In August 1997, the Company settled its lawsuit with BellSouth  arising
from certain work performed by a subcontractor  of the Company from 1991 to 1993
for an amount less than originally claimed by BellSouth.

         All of the claims asserted in the lawsuits  described  above,  with the
exception  of the second  lawsuit  filed by Albert Kahn,  arise from  activities
undertaken  prior to March 1994, the date of the consummation of the acquisition
of the Company by the Mas Family.

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






ITEM 2
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION

Overview

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

         In April  1996,  the Company  purchased  Sintel,  a company  engaged in
telecommunications  infrastructure  construction  services in Spain,  Argentina,
Chile and Peru,  from  Telefonica.  The Sintel  acquisition  gave the  Company a
significant international presence and more than doubled the size of the Company
in terms of revenue and number of employees.  In Argentina,  Chile and Peru, the
Company  operates  through  unconsolidated  50% joint ventures.  See Notes 2 an
5 to the Condensed  Consolidated Financial Statements for pro forma financial
information and  geographic  information,  respectively.  The  period  ended 
June 30,  1996includes the results of operation of Sintel from May 1, 1996 on.

Results of Operations

         Revenue is  generated  primarily  from  telecommunications  and related
infrastructure  services.  Infrastructure  services  are  provided to  telephone
companies, public utilities, CATV operators, other telecommunications providers,
governmental agencies and private businesses.

         Costs of revenue includes  subcontractor costs and expenses,  materials
not supplied by the customer,  fuel,  equipment  rental,  insurance,  operations
payroll and employee benefits.

         General and  administrative  expenses include  management  salaries and
benefits, rent, travel, telephone and utilities,  professional fees and clerical
and administrative overhead.

     Three Months Ended June 30, 1997 vs. Three Months Ended June 30, 1996.


         The  following  table  sets  forth  certain   historical   consolidated
financial  data as a  percentage  of revenue for the three months ended June 30,
1997 and 1996.

Interest and dividend income and other income, net,
  equity in unconsolidated companies and minority
  interest                                                                          1.0%                  2.0%
Income from continuing operations                                                   7.6%                  5.9%


         Revenue  increased  30.3% from $108.6 million in 1996 to $141.5 million
in 1997 while  operating  income  increased  54.7%  from $11.4  million to $17.6
million. A significant portion of this growth is a direct result of acquisitions
including a full second  quarter in 1997 for Sintel  ($55.5  million in revenue)
compared to the  inclusion of two months of operations in the quarter ended June
30, 1996 ($37.5 million in revenue).  Domestic  operations,  which accounted for
$71.1 million of 1996 revenue,  grew 21% in revenue to $86.0 million in 1997 and
contributed $11.9 million to operating income.





         Depreciation  and  amortization  costs were $3.8  million for  domestic
operations  in the second  quarter of 1997 as compared to $2.5  million in 1996.
Depreciation and amortization costs relating to international operations,  which
are less capital intensive, were $689,000 for the second quarter of 1997 or 1.2%
of international  revenue. The increase in domestic  depreciation expense is due
to  increased  capital  expenditures  made in the latter part of 1996 as well as
depreciation and amortization expense related to acquisitions.

         Although domestic general and  administrative  expenses as a percentage
of  revenue  decreased  slightly  from 9.8% in 1996 to 9.7% in 1997,  the dollar
amount  increased  $1.4  million  primarily  due to  acquisitions.  General  and
administrative  expenses  related  to  international  operations  were  16.6% of
revenue.

         Interest expense  decreased  $848,000 from $3.4 million in 1996 to $2.6
million  in  1997   primarily  due  to  the  conversion  of  the  Company's  12%
Subordinated  Convertible  Debentures to Common Stock on June 30, 1996 and lower
interest  costs  incurred by Sintel (in dollars and pesetas) to fund its working
capital needs .

         Interest and dividend income,  other income, net, equity in earnings of
unconsolidated  companies and minority  interest  decreased from $2.2 million in
1996 to $1.2 million in 1997  primarily as a result of the Company's  conversion
of a note  receivable  to an equity  investment  and  certain  termination  fees
associated with the Company refinancing its domestic credit facility.  See Notes
3 and 4 to the Condensed Consolidated  Financial Statements.  As a result of the
prepayment  of  the  Fleet  Credit  Facility,  deferred  financing  costs  and a
termination fee totaling $690,000 were expensed in the second quarter of 1997.


       Six Months Ended June 30, 1997 vs. Six Months Ended June 30, 1996.


         The  following  table  sets  forth  certain   historical   consolidated
financial data as a percentage of revenue for the six months ended June 30, 1997
and 1996.

         Revenue increased by approximately  $100.5 million or 58.6% from $171.2
million in 1996 to $271.6 million in 1997. Operating income increased 85.4% from
$17.9  million in 1996 to $33.1  million  in 1997.  Domestic  operations,  which
accounted for $133.6  million of 1996  revenue,  grew 20.0% in revenue to $160.4
million in 1997 and  contributed  $22.0 million to operating  income compared to
$14.2 million in 1996.  Domestic growth was generated primarily by acquisitions.
Revenue  generated by  international  operations  increased $73.7 million from $
37.5 million in 1996 to $111.2 million in 1997 due primarily to the inclusion of
six months of operations in 1997 compared to only two months in 1996.

         Depreciation and amortization costs were $8.3 million for 1997 compared
to $5.3 million in 1996. Domestic  depreciation expense for the six months ended
June 30, 1997 was $6.9  million or 4.3% of domestic revenue compared to $4.7 
million or 3.5% of domestic revenue in 1996. The increase is due to increased  
capital  expenditures made in the latter part of 1996 as well as depreciation 
and amortization expense related to acquisitions.

         General and administrative expenses as a percentage of revenue increase
from  11.2%  in  1996 to  12.9%  in  1997  due  primarily  to the  inclusion  of
international general and administrative  expenses for the six months ended June
30,  1997.  For  the  comparable  period  in  1996,  international  general  and
administrative expenses were only included for





the two months ended June 30, 1996.  The dollar  amount of domestic  general and
administrative  expenses  has  increased  from  $13.5  million  in 1996 to $16.0
million  in 1997  primarily  due to  acquisitions.  General  and  administrative
expenses related to international operations were 17.2% of international revenue
for the six months  ended June 30,  1997.  Sintel's  general and  administrative
expenses in terms of local  currency have continued to decline since the quarter
ended September 30, 1996.

         Interest expense  increased  $348,000 from $5.1 million in 1996 to $5.4
million in 1997 primarily due to the inclusion of interest costs associated with
Sintel's  working  capital  need for the entire  period in 1997  compared to two
months in 1996.  Partially  offsetting  the increase was the  conversion  of the
Company's 12%  Subordinated  Convertible  Debentures to Common Stock on June 30,
1996.

          Interest and dividend income, other income, net, equity in earnings of
unconsolidated  companies and minority interest decreased from $3.5 million in 
1996 to $ 2.9  million in 1997  primarily  as a result of the  Company's
conversion of a note receivable to an equity  investment.  As a result of the
prepayment of the Fleet Credit  Facility,  deferred  financing  costs and a
termination  fee totaling  $690,000 were expensed in the second  quarter of 
1997.  Partially offsetting the decline were interest income and other fees
earned and collected on short-term  customer project financing  provided by the 
Company. 

Financial Condition, Liquidity and Capital Resources

         The  Company's  primary  source  of  liquidity  has been cash flow from
operating activities,  external sources of financing,  and the proceeds from the
sale of  non-core  assets.  During the six months  ended  June 30,  1997,  $29.8
million  was  generated  from  operations  compared  to  $42.7  million  in  the
comparable  period of 1996. Also, during the six months ended June 30, 1997, the
Company invested cash of $12.5 million in acquisitions and received $7.6 million
from the sale of non-core  assets.  Cash paid for capital  expenditures was $8.2
million.  The Company used its excess cash to repay debt,  principally under its
revolving  credit   facilities  with  a  wholly  owned  finance   subsidiary  of
Telefonica.  See Note 4 to the Condensed Consolidated  Financial Statements.  In
June 1997, the Company  refinanced its domestic credit facility with BankBoston.
See Note 4 to the Condensed Consolidated Financial Statements.

         As of June 30, 1997,  working capital was approximately  $102.4 million
compared to working capital of approximately $124.3 million at December 31, 1996
(excluding   the  note   receivable   that  was  converted   into  stock  of  an
unconsolidated   company   during  June   1997--see  Note  3  to  the  Condensed
Consolidated  Financial  Statements).  Included  in working  capital are the net
assets of discontinued  operations and real estate held for sale.  Proceeds from
the  sale or  repayment  of these  assets  will be used  for  general  corporate
purposes including furthering the Company's growth strategy.

         During the six months ended June 30, 1997, the Company  completed seven
acquisitions  and increased  its  investment in  unconsolidated  companies.  The
combined cash  consideration  for these  transactions  amounted to approximately
$16.3 million.  Additionally,  the Company raised  approximately $3.2 million in
equity.

         The Company  continues to pursue a strategy of growth through  internal
growth and expansion through acquisitions and joint ventures. Subsequent to June
30, 1997, the Company  completed two additional  acquisitions (see Note 2 to the
Condensed Consolidated  Financial  Statements).  The Company anticipates that it
will  continue  making  acquisitions  and that the  Company's  growth as well as
operating cash  requirements,  capital  expenditures  and debt service,  will be
funded from cash flow generated by operations, external sources of financing and
the sale of non-core assets.

         The Company  conducts  business in several foreign  currencies that are
subject to  fluctuations in the exchange rate relative to the U.S.  dollar.  The
Company  does not enter into foreign  exchange  contracts.  It is the  Company's
intent to utilize foreign  earnings in the foreign  operations for an indefinite
period  of time  or  repatriate  those  earnings  when  its is  considered  cost
effective.  However,  as a means of hedging its balance sheet currency risk, the
Company  attempts  to  balance  its  foreign  currency  denominated  assets  and
liabilities.  There can be no  assurance  that a balance can be  maintained.  In
addition,  the  Company's  results of  operations  from foreign  activities  are
translated into U.S. dollars at the average  prevailing rates of exchange during
the period  reported,  which  average  rates may differ from the actual rates of
exchange in effect at the time of the actual conversion into U.S.  dollars.  The
Company  currently  has no plans to  repatriate  significant  earnings  from its
international operations.





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