NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 1998


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 financial statements and notes thereto included in the Company's annual
report on Form 10-K and Form 8-K filed  September  8,  1998,  for the year ended
December 31, 1997.  The year end  condensed  balance sheet data was derived from
the Form 8-K 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.  Certain prior year amounts have been reclassified
to conform to the current presentation.

     During the second quarter of 1998, the Company applied purchase  accounting
to two 1997 acquisitions  previously  accounted for using  pooling-of-interests.
The  change  occurred  due to  transactions  with  management  of  the  acquired
companies  which  occurred in the second  quarter of 1998 and the  potential for
future  consideration that may have required the use of purchase accounting (see
Note 8). The change in accounting resulted in an increase to capital surplus and
intangible  assets of $53 million.  No other  significant  changes to previously
reported  balance sheet amounts were recorded.  The resulting  goodwill is being
amortized  over 40 years.  As a result,  third quarter and nine month results in
1998  include  amortization  expense of $333,000  and $1 million,  respectively,
related to additional amortization expense from the change in accounting method.
For both the third quarter and nine month period in 1997,  amortization  expense
of approximately $200,000 is included in operating results.

2.       COMPREHENSIVE INCOME

     The  Company  has  adopted  Statement  of  Financial  Accounting  Standards
("SFAS") No. 130, "Reporting  Comprehensive Income", which establishes standards
for the  reporting  and display of  comprehensive  income and its  components in
general purpose  financial  statements for the year ended December 31, 1998. The

3.       ACQUISITIONS

     During the nine months  ended  September  30, 1998,  the Company  completed
certain  acquisitions which have been accounted for under the purchase method of
accounting.  Accordingly,  the results of  operations  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 1998 or
1997, pro forma results of operations  would not have differed  materially  from
actual results.  Acquisitions  made in 1998 were M.E.  Hunter,  Inc. of Atlanta,
Georgia,  C  &  S  Directional  Boring,  Inc.  of  Purcell,   Oklahoma,   Office
Communications Systems, Inc. of Inglewood, California, Phasecom Systems, Inc. of
Toronto,   Canada,   P&E  Electric  Company,   Inc.  of  Nashville,   Tennessee,
Lessard-Nyren   Utilities,   Inc.  of  Hugo,  Minnesota,   Electronic  Equipment
Analyzers,  Inc. of  Raleigh,  North  Carolina,  Cotton and Taylor of Las Vegas,
Nevada,  Stackhouse,   Inc.  of  Goldsboro,  North  Carolina,  Martin  Telephone
Contractors,   Inc.   of   Cades,   South   Carolina,   ten   telecommunications
infrastructure and utility contractors with operations primarily in the western,
northern and  southeastern  United States as well as Canada.  Additionally,  the
Company   made   four   international    acquisitions   of    telecommunications
infrastructure  contractors:  CIDE Engenharia Ltda. of Brazil, Acietel Mexicana,
S.A.  of Mexico,  Artcom  Services,  Inc.  of Puerto  Rico and Proyco  Ltda.  of
Colombia.
       
     Intangible   assets  of   approximately   $  152  million   resulting  from
acquisitions  since 1996 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 acquisitions is being amortized on
a  straight-line  basis over a range of 15-40  years.  The Company  periodically
reviews goodwill to assess recoverability.

4.       DEBT




         Debt is comprised of the following (in thousands):

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 1998


     The Company has a $125.0 million  revolving credit  facility,  (the "Credit
Facility")  from a group  of  financial  institutions  led by  BankBoston,  N.A.
maturing on June 9, 2000. The Credit Facility is  collateralized by the stock of
the  Company's  principal  domestic  subsidiaries  and a portion of the stock of
Sintel, S.A., the Company's Spanish subsidiary ("Sintel").
        
     Additionally,  the Company has several  credit  facilities  denominated  in
Spanish  Pesetas.  At September 30, 1998 and December 31, 1997,  the Company had
$67.9  million (9.6 billion  Pesetas) and $50.6  million (7.7 billion  Pesetas),
respectively,  of debt denominated in Pesetas, including $24.4 million and $22.3
million, respectively,  remaining under the acquisition debt incurred to acquire
Sintel.  The Company has paid a portion of the December 31, 1997  installment of
the acquisition debt. Management expects to settle this obligation in connection
with the proposed sale of its Sintel subsidiary (see Note 8).

     On January  30,  1998,  the  Company  sold  $200.0  million,  7.75%  senior
subordinated notes (the "Notes") due in 2008 with interest due semi-annually.

     The Credit Facility and Notes contain certain  covenants that,  among other
things,  restrict the payment of dividends  and limit the  Company's  ability to
incur additional  debt,  create liens,  dispose of assets,  merge or consolidate
with another entity or make other  investments or acquisitions.  These covenants
also require the Company to maintain minimum amounts of shareholders' equity and
to meet certain financial ratio coverages,  among others,  minimum ratios at the
end of  each  fiscal  quarter  of  debt  to  earnings  before  interest,  taxes,
depreciation and amortization and earnings to interest expense.

5.       OPERATIONS BY GEOGRAPHIC AREAS

telecommunications  infrastructure construction services in North America, Spain
and  the  Caribbean  and  Latin  American  region  (CALA),   primarily   Brazil.

     There are no material 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,  real  estate  held for sale,  notes  receivable  and
goodwill of which  approximately  $152 million is included in other assets.  The
Company  expects  to  broaden  its  segment  disclosure  to  provide  additional
information  on product lines  pursuant to FASB  Statement  No. 131  Disclosures
about Segments of an Enterprise and Related Information.


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,    S.A.
("Telefonica"),   BellSouth   Telecommunications  Corp.  ("BellSouth")  and  the
operating companies of Telecomunicacoes  Brasileiras S.A. ("Telebras").  For the
nine months  ended  September  30,  1998,  approximately  14%, 13% and 7% of the
Company's revenue was derived from services performed for Telefonica,  Telebras,
and BellSouth,  respectively.  During the nine months ended  September 30, 1997,
the Company  derived 27%, 13% and 7% of its revenue from  Telefonica,  BellSouth
and Telebras,  respectively.  Although the Company's  strategic  plan  envisions
diversification  of its  customer  base,  the Company  anticipates  that it will
continue  to derive a  significant  portion of its  revenue  in the future  from
certain of these customers (see Note 8).


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.

     In November 1993,  Mr. Kahn filed a class action and  derivative  complaint
against the Company,  the then members of its Board of  Directors,  and Jorge L.
Mas, Jorge Mas and Juan Carlos Mas, the principal  shareholders  of the Company.
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 the Mas
family 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.

     There has been no activity in either of these lawsuits in more than a year.
The Company  believes that the  allegations  in each of the lawsuits are without
merit and intends to defend these lawsuits vigorously.

     In November 1997, Church & Tower, Inc. a subsidiary of the Company ("Church
and Tower") filed a lawsuit against  Miami-Dade County (the "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 Church &
Tower under a  multi-year  agreement to perform  road  restoration  work for the
Miami-Dade Water and Sewer Department  ("MWSD"), a department of the County, and
the County's  wrongful  termination of the agreement.  The County has refused to
pay amounts due to Church & Tower under the agreement until alleged overpayments
under the  agreement  have been  resolved,  and has  counterclaimed  against the
Company seeking damages that the Company  believes will not exceed $2.1 million.
The  Company  believes  that any amounts  due to the County  under the  existing
agreement  are not  material  and may be  recoverable  in whole or in part  from
Church & Tower  subcontractors  who actually  performed the work and whose bills
were submitted directly to the County.

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

     The Company  continues to pursue a strategy of growth through  acquisitions
and internal  expansion.  During 1998, the Company completed 14 acquisitions for
$88.2 million in cash and seller financing.  Additionally,  the Company believes
that  there are  significant  business  opportunities  available  to it that may
require the Company to provide customer financing in connection with the sale of
its services.  As of September 30, 1998,  the Company had entered into financing
agreements to provide financing to two customers.  As of September 30, 1998, the
Company  had $19.8  million  outstanding  under  these  agreements.  The Company
anticipates  that it will provide an additional $20.0 million of financing under
these agreements over the next 12 months.

     The Company has  committed  to continue  developing  a PCS  cellular  phone
system in  Paraguay  of which the  Company  owns 90%.  The  Company  anticipates
investing  approximately  $20.0 million for the  development of this system over
the next 12 months.


8.       SUBSEQUENT EVENTS

     In October  1998,  the Company  announced  an agreement to sell its Spanish
subsidiary Sintel to a group of investors led by Inversiones  Ibersuizas S.A., a
Spanish  investment  firm.  The agreement is for a fixed purchase price plus the
assumption of all of Sintel's  consolidated  debt. The agreement includes all of
Sintel's  affiliates,  including  its  operations  in Spain,  Argentina,  Chile,
Colombia,  Peru,  Puerto Rico and  Venezuela.  The closing of the  agreement  is
subject to satisfactory due diligence and a number of other contingencies. Until
all of the contingencies are met, there can be no assurance that the transaction
will close. The closing is anticipated to occur before December 31, 1998.

     The Company is  negotiating  with  management  personnel  at certain of the
Company's subsidiaries acquired in 1997 for the continuation of their employment
and/or  consulting   services  for  five  years  from  the  date  of  definitive
agreements.  In  addition,  pre-existing  non-competition  and  non-solicitation
agreements are proposed to be modified and to be extended to a term of ten years
from  the  date  of  the  definitive  agreements.  As  consideration  for  these
agreements,  the Company proposes to pay certain compensation for the employees'
employment and non-competition  agreements,  including cash compensation,  stock
and option awards and certain other  compensation.  The Company also proposes to
repurchase  shares of the Company's  common stock issued in connection  with the
1997 acquisitions and owned by certain of these employees in three  transactions
over the next thirteen months.  In total these  agreements,  if concluded,  will
require cash payments  (including for the repurchase of the common stock) of $35
million in 1998,  $32 million in two  installments  in 1999 and $3.2  million in
2000,  2001 and 2002.  The  definitive  agreements  are still subject to further
negotiation  and  to  final  Board  approval.  There  can be no  assurance  that
definitive agreements will be executed, or if executed, that they will be at the
terms described above.

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


     Certain  statements in this Quarterly Report are  forward-looking,  such as
statements  regarding  the  Company's  future  growth and  profitability.  These
forward looking statements are based on the Company 's current  expectations and
are  subject  to a number of risks and  uncertainties  that could  cause  actual
results in the future to significantly  differ from results expressed or implied
in any forward-looking statements included in this Quarterly Report. These risks
and uncertainties  include,  but are not limited to, the Company's  relationship
with  key  customers,  implementation  of the  Company's  growth  strategy,  and
seasonality.  These and other risks are detailed in this Quarterly Report and in
other   documents  filed  by  the  Company  with  the  Securities  and  Exchange
Commission.

Overview

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

     During the nine months  ended  September  30,  1998,  the  Company's  North
American  operations  were  affected  by a number of  factors  including  severe
weather  conditions  experienced  during the first quarter of 1998,  among other
things, and performance issues in two divisions.

     In March 1998,  Sintel entered into an agreement with its unions to resolve
a labor dispute.  As a result of the agreement  reached,  the Company recorded a
severance charge related to operational  personnel and administrative  personnel
of $1.9  million  and $11.5  million,  respectively.  The total  charge of $13.4
million negatively impacted the Company's operating margins in the first quarter
of 1998.  On October 16,  1998,  the Company  announced an agreement to sell its
Spanish  subsidiary  and its  affiliates in Argentina,  Chile,  Colombia,  Peru,
Puerto Rico and Venezuela to focus on operations in North America.

     In July 1998, the Brazilian government privatized the Telebras wireline and
wireless  telephone  companies.  As a result of the  privatization,  the Company
anticipates that it will increase its sales in the CALA region.  However, global
deregulation and consolidation within the telecommunications  industry may delay
or depress capital  spending among  telecommunications  providers as they assess
their  new  business  plans  and  strategies  and  focus on  administrative  and
operational issues associated with their acquisitions or alliances.

MANAGEMENT'S DISCUSSION AND ANALYSIS

                Three Months Ended September 30, 1998 compared to
                     Three Months Ended September 30, 1997

Results of Operations

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

     The following table sets forth certain  historical  consolidated  financial
data and  supplemental  information  as a  percentage  of revenue by  geographic
region for the three  months  ended  September  30, 1998 and 1997 (in  thousands
unless otherwise indicated).

MANAGEMENT'S DISCUSSION AND ANALYSIS


     Revenue increased $104 million or 56% to $288.6 million in 1998 as compared
to $184.6  million in 1997.  Revenue from North  American  operations  increased
$93.5  million,  or 89%, to $198.9 million in 1998 as compared to $105.4 million
in 1997. North American  revenue growth was primarily  generated by acquisitions
completed in the latter part of 1997 and during 1998.  Revenue  generated by the
combined Spanish and CALA regions  (collectively  referred to as "international"
operations)  increased  $10.6  million,  or 13.4%,  to $89.7  million in 1998 as
compared to $79.1 million in 1997 due primarily to  acquisitions  of entities in
Colombia and Puerto Rico.  Revenues in the Company's CALA region were negatively
impacted  by delays in the  privatization  of the  Brazilian  telecommunications
industry.

     Gross profit  (revenue less cost of revenue),  excluding  depreciation  and
amortization,  increased  $28.4 million,  or 68%, to $70.1 million,  or 24.3% of
revenue in 1998 as compared to $41.7 million, or 22.6% of revenue in 1997. North
American  gross margins  (gross profit as a percentage of revenue)  increased to
26.1% in 1998  from  25.9% in  1997.  The  increase  in  gross  margins  was due
primarily to  acquisitions  made in the third quarter of 1997 of work generating
higher  margins.  International  gross  margins  increased  to  20.3% in 1998 as
compared to 18.2% in 1997  primarily  due to the  completion  of certain  higher
margin contracts in 1998.  Additionally,  the Company's newly formed CALA region
reflected  improved  margins of 16.7% as  compared  to 15% in 1997.  In the CALA
region,  the Company  typically  operates in a project manager  capacity,  which
results in lower margins than the Company's North American operations because of
greater use of subcontractors.

     Depreciation  and  amortization  increased $6.1 million,  or 107%, to $11.8
million in 1998 from $5.7  million in 1997.  The  increase in  depreciation  and
amortization  was a result of increased  amortization of intangibles  associated
with  acquisitions,  as well as increased  capital  expenditures  during 1998 to
support  revenue  growth.   As  a  percentage  of  revenue,   depreciation   and
amortization was 4.1% and 3.1% of revenue for 1998 and 1997, respectively.

     General and administrative expenses increased $12.8 million, or 67%, to $32
million,  or 11.1% of revenue for 1998 from $19.2  million,  or 10.4% of revenue
for 1997.  The  increase in dollar  amount is  primarily  due to North  American
general and administrative  expenses which were $19.6 million,  or 9.8% of North
American revenue in 1998,  compared to $9.4 million, or 8.9% of domestic revenue
for 1997. The increase in dollar amount of domestic  general and  administrative
expenses  stems  primarily  from  acquired  companies  and  an  increase  in the
allowance for doubtful  accounts of $1 million in connection  with  management's
ongoing  evaluation  of the  collectability  of its  receivables.  International
general and administrative  expenses increased $2.6 million,  or 26.5%, to $12.4
million,  or 13.8% of international  revenue in 1998 from $9.8 million, or 12.4%
of  international  revenue for 1997. The increase in general and  administrative
expenses  resulted from the Company's  expansion  into the CALA region in August
1997. General and administrative expenses for the CALA region were approximately
$2.9 million.

     The Company  generated  operating income of $26.3 million for 1998 compared
to  $16.8  million  for  1997 or 9.1% of  revenue  for  both  periods.  Domestic
operating  income  declined  to 11.5% of revenue in 1998 as compared to 12.1% in
1997  as a  result  of a $1  million  increase  in the  allowance  for  doubtful
accounts.  Favorably  impacting  1998  operating  income were  acquisitions  and
short-term  projects with attractive  pricing.  International  operating  income
decreased  to $3.4  million in 1998 from $4.0  million in 1997 due  primarily to
increases in general and administrative  expenses  associated with the Company's
newly established Brazilian operation.

     Interest  expense  increased $5.2 million or 200%, to $7.8 million for 1998
from $2.6 million in 1997  primarily  due to the Company's  $200.0  million bond
offering completed in February 1998.  Offsetting the increase was lower interest
rates on Spanish  borrowings.  See "Financial  Condition,  Liquidity and Capital
Resources."

     Interest and dividend  income,  other  income,  net,  equity in earnings of
unconsolidated  companies  and  minority  interest  increased  to  $3.9  million
compared to $402,000  during the 1997  period due to a  significant  increase in
interest  income  related to temporary  short-term  investments by the Company's
Brazilian operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS

     Revenue  increased  $264.6  million,  or 58%, to $720.8  million in 1998 as
compared to $456.2 million in 1997.  North  American  revenue  increased  $208.5
million,  or 78% from $265.9  million to $474.4  million.  The increase in North
American revenue was primarily generated by acquisitions completed in the latter
part of 1997 and 1998. Revenue generated by international  operations  increased
$56.1 million, or 29.5%, to $246.4 million in 1998 as compared to $190.3 million
in 1997 due  primarily to the inclusion of the  Company's  Brazilian  operations
which contributed $95 million to 1998 results. The Company's Spanish revenue was
negatively  impacted in 1998 by a  reduction  in the volume of work by its major
customer,  Telefonica,  whose  investment  focus has  shifted to Latin  America,
specifically  Brazil.  Revenues in the  Company's  CALA  region were  negatively
impacted  by delays in the  privatization  of the  Brazilian  telecommunications
industry.

     Gross profit  (revenue less cost of revenue),  excluding  depreciation  and
amortization,  increased $44.8 million,  or 38%, to $163.1 million,  or 22.6% of
revenue  in 1998 as  compared  to $118.3  million,  or 25.9% of revenue in 1997.
North American gross margins (gross profit as a percentage of revenue) decreased
to 24.1% in 1998 from 27.2% in 1997.  The  decline in gross  margins was related
to,  among  other  things,  pricing  on  certain  contracts,  some of which have
recently been re-negotiated.  In addition,  1997 results were favorably impacted
by certain short-term  projects with attractive  pricing.  Spanish gross margins
decreased  to 21.9% in 1998 as  compared to 26.2% in 1997  primarily  due to the
increase in labor costs  associated  with its new labor agreement in Spain and a
$1.9 million  charge for  severance  for direct labor  personnel.  The Company's
newly  formed CALA  operations  reported an improved  margin of 16.2% in 1998 as
compared to 15% in 1997. In the CALA region, the Company typically operates in a
project  manager  capacity,  which  results in lower  margins than the Company's
North  American  operations  since it  subcontracts  a larger  proportion of its
work.

     Depreciation  and  amortization  increased  $17  million,  or 121%,  to $31
million in 1998 from $14  million in 1997.  The  increase  in  depreciation  and
amortization was a result of increased capital  expenditures in 1998, as well as
depreciation and amortization  associated with acquisitions.  As a percentage of
revenue, depreciation and amortization was 4.3% and 3.1% of revenue for 1998 and
1997, respectively.
  
   General and administrative expenses increased $45 million, or 83%, to $99.4
million,  or 13.8% of revenue for 1998 from $54.4  million,  or 11.9% of revenue
for  1997.  The  increase  is  primarily  due  to  North  American  general  and
administrative  expenses  which were $54.7  million,  or 11.5% of North American
revenue in 1998,  compared to $25.4 million,  or 9.6% of North American  revenue
for  1997.  The  increase  in  dollar  amount  of  North  American  general  and
administrative expenses is due primarily to acquisitions. North American general
and  administrative  expenses  increased  as a  percentage  of  revenues  due to
increases  in the  allowance  for  doubtful  accounts  as well as $4  million in
special   charges   recorded  in  the  first   quarter  of  1998.   General  and
administrative expenses for international operations increased $15.8 million, or
55%,  to $44.7  million,  or 18.2% of  international  revenue in 1998 from $28.9
million,  or 15.2% of  international  revenue for 1997.  The increase in Spain's
general and  administrative  expenses was primarily due to severance  charges of
$12.9 million  associated  with the  agreement  reached with the union to reduce
administrative  personnel  in excess of 200 people.  General and  administrative
expenses for the Company's  CALA region were  approximately  $7.1  million.  The
Company did not operate in this region until August 1997.

     The Company generated  operating income of $32.7 million or 4.5% of revenue
for 1998  compared  to $49.9  million  or 10.9% of revenue  for 1997.  Favorably
impacting 1997 operating income were short-term projects with attractive pricing
and terms.  International  operating  income  decreased to (624,000)  from $15.1
million due primarily to the  aforementioned  severance  charges recorded by the
Company's Spanish operations in 1998.

     Interest expense increased $11.9 million or 149%, to $19.9 million for 1998
from $8.0 million in 1997,  primarily due to the Company's  $200.0  million bond
offering completed in February 1998. See - "Financial  Condition,  Liquidity and
Capital Resources."

     Interest and dividend  income,  other  income,  net,  equity in earnings of
unconsolidated  companies  and  minority  interest  increased  to  $7.7  million
compared to $3.4 million in 1997 due to temporary short-term  investments offset
by an increase in minority  interest  attributable  to the  Company's  Brazilian
operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Financial Condition, Liquidity and Capital Resources

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

     Net cash  provided by  operating  activities  for the 1998 period was $14.9
million,  compared to $27.8 million in the 1997 period. This decrease was due to
a breakeven result in the first quarter of 1998 absent non-recurring charges and
fluctuations in working capital,  particularly  increases in accounts receivable
and unbilled revenue from Brazilian and North American operations.

     As of September 30, 1998, working capital totaled $148.7 million,  compared
to working capital of $124.1 million at December 31, 1997.

     The Company  invested  cash,  net of cash  acquired,  in  acquisitions  and
investments  in  unconsolidated  companies  totaling  $95.8 million  during 1998
compared  to $25.7  million in 1997.  During  1998,  the  Company  made  capital
expenditures of $57.5 million, primarily for machinery and equipment used in the
production  of  revenue,  compared  to $15.8  million in 1997.  The  increase in
capital expenditures was related to acquisitions,  internal growth and expansion
into new contract areas.

     The Company is  negotiating  with  management  personnel  at certain of the
Company's subsidiaries acquired in 1997 for the continuation of their employment
and/or  consulting   services  for  five  years  from  the  date  of  definitive
agreements.  In  addition,  pre-existing  non-competition  and  non-solicitation
agreements are proposed to be modified and to be extended to a term of ten years
from  the  date  of  the  definitive  agreements.  As  consideration  for  these
agreements,  the Company proposes to pay certain compensation for the employees'
employment and non-competition  agreements,  including cash compensation,  stock
and option awards and certain other  compensation.  The Company also proposes to
repurchase  shares of the Company's  common stock issued in connection  with the
1997 acquisitions and owned by certain of these employees in three  transactions
over the next thirteen months.  In total these  agreements,  if concluded,  will
require cash payments  (including for the repurchase of the common stock) of $35
million in 1998,  $32 million in two  installments  in 1999 and $3.2  million in
2000,  2001 and 2002.  The  definitive  agreements  are still subject to further
negotiation  and  to  final  Board  approval.  There  can be no  assurance  that
definitive agreements will be executed, or if executed, that they will be at the
terms described above.

     The Company  continues to pursue a strategy of growth through  acquisitions
and internal  expansion.  During 1998, the Company completed 14 acquisitions for
$88.2 million in cash and seller financing.  Additionally,  the Company believes
that  there are  significant  business  opportunities  available  to it that may
require the Company to provide customer financing in connection with the sale of
its services.  As of September 30, 1998,  the Company had entered into financing
agreements to provide financing to two customers.  As of September 30, 1998, the
Company  had $19.8  million  outstanding  under  these  agreements.  The Company
anticipates  that it will provide an additional $20.0 million of financing under
these agreements over the next 12 months.

     The Company has  committed  to continue  developing  a PCS  cellular  phone
system in  Paraguay  of which the  Company  owns 90%.  The  Company  anticipates
investing  approximately  $20.0 million for the  development of this system over
the next 12 months. 

     The  Company  expects  to  finance  its  working  capital  needs,   capital
expenditures,  debt service  obligations and other commitments and contingencies
from cash  generated  from  operations,  the sale of  investments  and  non-core
assets, borrowings under the existing Credit Facility, and funds from additional
borrowings or the issuance of additional debt or equity securities. There can be
no assurance that the Company will be able to obtain additional capital,  borrow
additional  funds in a timely manner or on favorable terms. Nor can there be any
assurances that the Company will be able to obtain additional financing.  If the
Company is unable to do so, the  Company  may be required to delay or reduce its
proposed  expenditures  or sell  additional  assets in order to meet its  future
obligations.

     On October  16,  1998,  the Company  announced  its  intention  to sell its
Spanish  subsidiary  and its  affiliates in Argentina,  Chile,  Colombia,  Peru,
Puerto Rico and Venezuela to focus on operations in North America.  The proceeds
from the sale will be used for domestic acquisitions and internal expansion.

MANAGEMENT'S DISCUSSION AND ANALYSIS

     The Company  announced a stock  repurchase  program in April 1998.  Through
November 12, 1998,  the Company had purchased a total of 657,000  shares with an
average price of $20.06.  The Company may continue to purchase  shares from time
to time. The Credit Facility restricts the amount of shares that the Company may
repurchase up to an additional $10.3 million.

     In February 1998, the Company  issued $200.0  million  principal  amount of
7.75%  Senior  Subordinated  Notes  (the  "Notes")  due 2008 with  interest  due
semi-annually.  The Credit  Facility  and the Notes  contain  certain  covenants
which,  among other  things,  restrict  the payment of  dividends  and limit the
Company's  ability to incur  additional debt,  create liens,  dispose of assets,
merge  or  consolidate  with  another  entity  or  make  other   investments  or
acquisitions.  These  covenants  also  require the  Company to maintain  minimum
amounts of shareholders'  equity and to meet certain  financial ratio coverages,
among  others,  minimum  ratios  at the end of each  fiscal  quarter  of debt to
earnings before interest,  taxes,  depreciation and amortization and of earnings
to interest expense. See Note 4 of Notes to Condensed Consolidated Financial
Statements.

     The  Company  conducts  business  in several  foreign  currencies  that are
subject to  fluctuations in the exchange rate relative to the U.S.  dollar.  The
Company  does not enter into foreign  exchange  contracts.  It is the  Company's
intent to utilize foreign  earnings in the foreign  operations for an indefinite
period of time or until a decision to divest is made.  See Note 8 to Condensed
Consolidated Financial Statements. 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'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.

Year 2000

     The  Company  has been  assessing  the  impact of the Year 2000 issue as it
relates to its  information  systems and vendor supplied  application  software,
hardware and  non-information  systems such as fax  machines,  alarm systems and
other miscellaneous  systems. The Company and each of its operating subsidiaries
are in the process of  implementing  a readiness  program with the  objective of
having all of their  significant  business systems  functioning  properly before
January 1, 2000. Each operating  system is in a different stage of its year 2000
readiness.

     The first  step of the  Company's  readiness  program  is to  identify  the
internal business systems of the Company and its operating subsidiaries that are
susceptible to system failures or processing  errors.  This effort is in process
and those business systems considered most critical to continuing operations are
being given the highest priority.

     The Company expects to incur internal staff costs as well as consulting and
other  expenses  related to  infrastructure  to prepare the systems for the year
2000 testing and  conversion  of system  applications  which is expected to take
place  over  the  remaining  year  and  into  1999.   Through  normal,   planned
enhancements  of existing  systems,  development  of new systems and upgrades to
operating systems and databases already covered by maintenance  agreements,  the
Company  believes that the year 2000  compliance  will be achieved over the next
year.  The  Company's  vendor  supplied  application  software is provided  from
reputable  companies that have year 2000 compliant  software readily  available.
Assuming that  remediation  projects can be implemented as planned,  the Company
believes future costs relating to the Year 2000 issue, which will be expensed as
incurred,  will not have a material  adverse  impact on the Company's  business,
operations or financial condition.

     The  Company  has  also  initiated  formal  communications  with all of its
significant  customers to determine the extent to which the  Company's  customer
interface  systems are vulnerable to those third parties'  failures to remediate
their own year 2000 issues. The Company believes that issues related to the year
2000 with respect to its customers will not have a material adverse impact since
most  of the  Company's  customers  are  large  commercial  entities  which  are
addressing their own year 2000 issues.

MANAGEMENT'S DISCUSSION AND ANALYSIS


     Although the Company  expects its critical  systems to be compliant  during
mid 1999, there are no assurances that these results will be achieved.  Specific
factors that give rise to this uncertainty  include a possible loss of technical
resources  to perform the work,  failure to identify  all  susceptible  systems,
non-compliance by third parties whose systems and operations impact the Company,
and other similar uncertainties.
