                                 PROXY STATEMENT
                                 _______________

                         ANNUAL MEETING OF SHAREHOLDERS

                                  MAY 17, 2000
                                 _______________

                                     GENERAL

     The Board of Directors of MasTec,  Inc. ("MasTec") is furnishing this Proxy
Statement to solicit  proxies for use at the 2000 Annual Meeting of Shareholders
of MasTec,  to be held at our corporate  headquarters  located at 3155 N.W. 77th
Avenue, Miami, Florida, on Wednesday, May 17, 2000, at 9:30 a.m., local time.

     At the  Annual  Meeting,  our  shareholders  will be  asked  to vote on the
following  matters,  each of which is described in greater  detail  elsewhere in
this Proxy Statement:

     *    The election of two Class II directors for terms expiring in 2003;

     *    An  increase  in the  number of shares of Common  Stock  reserved  for
          issuance  under  MasTec's 1994 Stock  Incentive Plan from 2,500,000 to
          3,500,000 and certain related amendments to the plan; and

     *    Such other  business  as may  properly  be  brought  before the Annual
          Meeting.

     The Board of  Directors  recommends  that you vote FOR each of the nominees
for Class II director set forth in this Proxy  Statement and FOR the increase in
the shares reserved for issuance under the 1994 Stock Incentive Plan.

     This Proxy Statement and  accompanying  proxy and other materials are first
being  mailed on or about April 5, 2000 to  shareholders  of record on March 21,
2000. Only shareholders of record at the close of business on March 21, 2000 are
entitled to vote at the Annual Meeting.  If you are not present in person at the
Annual  Meeting,  your  shares can be voted only if  represented  by proxy.  The
shares  represented  by your  proxy  will  be  voted  in  accordance  with  your
instructions  only if you properly  complete,  sign and return the  accompanying
proxy card to our Corporate  Secretary prior to the Annual Meeting. If no choice
is specified, the shares represented by the proxy will be voted for the election
of all  nominees  for  director,  for the  increase in the shares  reserved  for
issuance  under the 1994 Stock  Incentive  Plan,  and in the  discretion  of the
holder of the proxy on all other  matters  that may  properly  come  before  the
Annual Meeting.  A proxy given pursuant to this  solicitation  may be revoked at
any time prior to its  exercise by written  notice  delivered  to our  Corporate
Secretary, by executing and delivering to our Corporate Secretary a proxy with a
later date, or by attending the Annual Meeting and voting in person.  Attendance
at the Annual Meeting will not, in itself, constitute revocation of a proxy.

<PAGE>

     MasTec's only class of voting  securities is its Common Stock. At March 21,
2000, there were 31,003,830 shares of our Common Stock outstanding, which is the
only class of MasTec's  capital stock  outstanding.  As of March 21, 2000 MasTec
had 4,569 record shareholders,  which does not include shareholders whose shares
are held of record by a brokerage firm or otherwise in "street name."

     Each  share of our  Common  Stock  entitles  its  holder to one vote on all
matters properly brought before the Annual Meeting.  The presence,  in person or
by  proxy,  of a  majority  of the  shares  entitled  to  vote is  necessary  to
constitute a quorum at the Annual Meeting. If a quorum is present, directors are
elected  by a  plurality  of the  votes  of  the  shares  voting  in  person  or
represented  by proxy at the  Annual  Meeting,  which  means  that the  nominees
receiving the highest number of votes will be elected to the Board of Directors.
If a quorum is present,  in order for the  increase in the shares  reserved  for
issuance under the 1994 Stock Incentive Plan to be approved, the number of votes
cast in favor of the  proposal  must be  greater  than the  number of votes cast
against the proposal.

     Shares that are entitled to vote but that are not voted at the direction of
the beneficial owner  ("abstentions"),  shares represented by proxies or ballots
that are  marked  "withhold  authority",  and votes  withheld  by brokers in the
absence of instruction  from  beneficial  holders  ("broker  nonvotes")  will be
counted  for the  purpose  of  determining  whether  there is a  quorum  for the
transaction of business at the Annual Meeting.  In determining  whether a matter
requiring  approval of a majority of the shares voting at the Annual Meeting has
been  approved or whether a nominee for director has received a plurality of the
shares, abstentions,  withheld votes and broker nonvotes will be disregarded and
will have no effect on the outcome of the vote.

                              ELECTION OF DIRECTORS

     The first matter that shareholders will be asked to vote upon at the Annual
Meeting is the  election  of two Class II  directors  for terms  expiring at the
annual  meeting  of  shareholders  in the year  2003.  The  Board  of  Directors
currently is comprised of eight  directors  elected in three  classes,  with two
Class I, three Class II, and two Class III  directors.  Directors  in each class
hold office for three-year terms. The terms of the classes are staggered so that
the term of one class  terminates  each year.  The terms of the current Class II
directors  expire at the Annual Meeting;  if elected,  the nominees for Class II
directors will serve until the annual shareholders meeting in 2003. The terms of
the Class III directors  expire at the annual  shareholders  meeting in 2001 and
the terms of the Class I directors  expire at the annual meeting of shareholders
in 2002.

     One of the current Class II directors,  Eliot Abbott,  has informed  MasTec
that he does not wish to stand for  reelection,  and the Board of Directors,  as
permitted  by our  bylaws,  has  resolved  that the Board of  Directors  will be
comprised of seven  directors  (subject to further  adjustment by the actions of
our Board of Directors or shareholders) following the expiration of the terms of
our current Class II directors at the Annual Meeting.  The reduction in the size
of the  Board of  Directors  will be  effected  by  electing  only two  Class II
directors at the Annual Meeting.
<PAGE>

     The following  individuals have been nominated by the Nominating  Committee
of the Board of  Directors  for election as the Class II directors to be elected
at the Annual Meeting:

     *  Olaf Olafsson
     *  William N. Shiebler

     Additional  background  information  regarding  each of these  nominees  is
provided  below.  MasTec has no reason to believe that either of these  nominees
will refuse or be unable to serve as a director if elected;  however,  if either
of the  nominees is unable to serve,  each proxy that does not direct  otherwise
will be voted for a substitute nominee designated by the Board of Directors.

     The election of directors  requires the affirmative  vote of a plurality of
the shares of Common Stock  voting in person or by proxy at the Annual  Meeting.
The Board of Directors  recommends  that you vote FOR each of the nominees named
above. Unless otherwise indicated,  the accompanying form of proxy will be voted
FOR the  election of each of the  nominees  for  election as a Class II director
named above.

Compensation of Directors

     Under MasTec's Non-Employee  Directors' Stock Option Plan, our non-employee
directors are eligible to receive  annually options to purchase shares of Common
Stock.  The amount and exercise price of the options granted under this plan are
set by the Compensation Committee.  Options issued under the plan are in lieu of
all other compensation to directors for their services as directors. MasTec does
not  separately   compensate  its  employee  directors  for  their  services  as
directors.  Directors are reimbursed for their reasonable  expenses in attending
Board and committee meetings.

Employment Agreements

     Effective January 1, 2000,  MasTec entered into a new employment  agreement
with Mr. Citron  relating to his employment as the Vice Chairman of the Board of
Directors,  President and Chief  Executive  Officer.  The new agreement is for a
term of two years unless earlier  terminated,  and provides that Mr. Citron will
be paid an annual salary of not less than $500,000 in 2000 and $600,000 in 2001.
The new  agreement  also provides for a bonus to be paid to Mr. Citron if MasTec
achieves certain budgeted levels of earnings before interest and taxes ("EBIT"),
and will be based on a percentage of EBIT,  which is consistent with our service
line presidents'  bonus plan.  Additionally,  if there is a change of control of
MasTec during Mr. Citron's  employment  term, Mr. Citron will be entitled to all
of the unpaid  portion of his  salary for the full term of this  agreement,  any
bonus  that he would  have  earned  for the year in which the  change of control
occurs, and to certain payments based on stock price levels as well as immediate
vesting  of any  previously  unvested  options.  This  agreement  also  contains
non-competition and non-solicitation provisions.

                     APPROVAL OF AN INCREASE IN THE NUMBER
                         OF SHARES RESERVED FOR ISSUANCE
                    UNDER MASTEC'S 1994 STOCK INCENTIVE PLAN

     MasTec has adopted and our shareholders  have previously  approved the 1994
Stock  Incentive Plan (the "Stock  Incentive  Plan").  The Stock  Incentive Plan
currently  provides for the  issuance of an  aggregate  of  2,500,000  shares of
Common Stock,  including  restricted stock and stock issued upon the exercise of
stock options. As of March 21, 2000, only 67,644 shares of Common Stock remained
available for issuance under the plan.

     On February 7, 2000,  the Board of  Directors  approved an amendment to the
Stock  Incentive  Plan to increase the maximum  number of shares of Common Stock
that may be issued under the plan by 1,000,000 and to make certain other related
amendments  to the plan.

     Shareholders  are being asked to consider and approve the  amendment to the
Stock Incentive Plan. Approval of the amendment requires the affirmative vote of
the holders of a majority of the shares of Common Stock  present in person or by
proxy at the Annual Meeting. The amendment will be approved if the votes cast in
favor of the amendment are greater than the votes cast against the amendment.

     The Board of Directors  believes that awards under the Stock Incentive Plan
serve to attract,  retain and motivate key employees, to enhance their incentive
to perform at the highest level and to contribute  significantly  to our success
by tying  the  compensation  of these  employees  to  MasTec's  performance  and
aligning  their  interests  with  the  long-term  interest  of  MasTec  and  its
shareholders.  The  Board of  Directors  believes  that the  proposed  amendment
furthers  these  objectives  by ensuring  that a sufficient  number of shares of
Common Stock are  available  to be granted or issued  under the Stock  Incentive
Plan.

     The Board  unanimously  recommends a vote FOR approval of the  amendment to
increase the number of shares of Common Stock that may be issued under the Stock
Incentive Plan. Unless otherwise indicated,  the accompanying form of proxy will
be voted FOR the approval of the amendment.


Summary of the Stock Incentive Plan

     The  following  is a  summary  of the  significant  features  of the  Stock
Incentive Plan, as it currently exists and as proposed to be amended.  A copy of
the plan,  as  proposed to be amended,  is attached to this Proxy  Statement  as
Exhibit "B."

     Number of Shares Covered by the Plan

     Subject to adjustment  as noted below,  the total number of shares that may
be optioned or awarded  under the Stock  Incentive  Plan  currently is 2,500,000
shares of Common  Stock,  of which  500,000  shares may be awarded as restricted
stock.  This amount will increase to 3,500,000 shares, of which 1,000,000 shares
may be awarded as  restricted  stock,  if the  proposed  amendment  to the Stock
Incentive Plan is approved by  shareholders.  No employee may receive,  over the
term of the Stock Incentive Plan, awards in the form of options to purchase more
than  500,000  shares  of Common  Stock,  which  number  would be  increased  to
1,000,000 if the  amendment is approved.  Any shares  subject to an option under
the Stock  Incentive Plan that for any reason  expires,  is  relinquished  or is
terminated  unexercised and any restricted  stock that is forfeited may again be
optioned or awarded under the Stock Incentive Plan, except that forfeited shares
are not available  for further  awards if the employee has realized any benefits
of ownership from the forfeited shares.

     Eligible Participants in the Plan

     Key employees,  including  officers,  of MasTec and its  subsidiaries,  are
eligible to participate in the Stock Incentive Plan. The Compensation  Committee
of the Board of Directors (the "Committee") administers the Stock Incentive Plan
and determines the recipients of options and awards,  their terms and conditions
within  the  parameters  of the Stock  Incentive  Plan and the  number of shares
covered by each option or award. The Committee may approve rules and regulations
to carry  out the  Stock  Incentive  Plan and its  decision  with  regard to any
question  arising under the Stock  Incentive Plan is final and  conclusive.  The
Committee members are not eligible to participate in the Stock Incentive Plan.

     No award or option  may be  granted  under the Stock  Incentive  Plan after
January 2004,  but awards or options  granted before that date may extend beyond
that date.  The Board of Directors  may amend,  alter or  discontinue  the Stock
Incentive  Plan,  but no amendment,  alteration or  discontinuation  may be made
which would (i) impair the right of any recipient of restricted  stock or option
or stock bonus  already  granted,  without his or her written  consent,  or (ii)
without the approval of the shareholders (A) increase the total number of shares
reserved  for the Stock  Incentive  Plan,  (B)  decrease  the option price of an
incentive  stock  option to less than 100% of the fair market value of the stock
on the date the option was granted,  (C) change the class of persons eligible to
receive an award of restricted  stock or options under the Stock Incentive Plan,
or (D) extend the  duration of the Stock  Incentive  Plan.  The  Committee  may,
retroactively or prospectively, amend the terms of any award of restricted stock
or option already granted without the holder's  consent so long as the amendment
does not impair the rights of the holder.

     Options and Option Price

     The option price per share is determined by the Committee,  but in the case
of an incentive  stock option may not be less than 100% of the fair market value
of a share of Common  Stock at the time the option is granted as reported on the
New York Stock  Exchange.  Options  granted under the Stock  Incentive Plan will
expire on a date  fixed by the  Committee,  but not more than 10 years  from the
date of grant in the case of incentive stock option.  Options become exercisable
over a vesting period after the date of grant determined by the Committee.

     Payment of the option price upon exercise of an option may be made in cash,
by the delivery of Common Stock already owned by the optionee,  by a combination
of cash and shares,  or in  accordance  with a cashless  exercise  program under
which shares of Common Stock may be issued directly to the optionee's  broker or
dealer upon receipt of the purchase price in cash from the broker or dealer.  No
optionee will have any rights to dividends or other rights of a shareholder with
respect to his or her shares  subject to the option until the optionee has given
written notice of exercise and has paid in full for such shares. Tax withholding
obligations  may be met by a withholding of stock  otherwise  deliverable to the
optionee under procedures approved by the Committee.

     Each option  granted under the Stock  Incentive  Plan may provide for stock
appreciation  rights,  that is, the right to exercise  the option in whole or in
part without  payment of the option  price.  If an option is  exercised  without
payment,  the optionee will be entitled to receive the excess of the fair market
value of the stock covered by the option on the date of exercise over the option
exercise  price.  This amount is payable in stock or in cash or in a combination
of stock and cash at the discretion of the Committee.

     If an optionee's  employment  terminates by reason of his or her retirement
under one of our retirement  plans or because of death or permanent  disability,
the  optionee's  option may thereafter be exercised by the optionee or by his or
her estate or  beneficiary  within the period  specified  in the option  (not to
exceed three years from the date of termination)  but not beyond the termination
date  of  the  option.  Unless  otherwise  determined  by the  Committee,  if an
optionee's employment terminates for any reason other than retirement, death, or
permanent  disability the optionee's  option will terminate upon  termination of
employment.  During the optionee's  lifetime,  the option is exercisable only by
the optionee and may not be  transferable  except by will or the laws of descent
and distribution.

     No  incentive  stock option may be granted to an employee who owns or would
own immediately before the grant of such option,  directly or indirectly,  stock
possessing  more than 10% of the total  combined  voting power of all classes of
MasTec's stock.  This  restriction does not apply if, at the time such incentive
stock  option is granted,  the option  price is at least 110% of the fair market
value of a share of Common  Stock on the date of grant and the  incentive  stock
option by its terms is not  exercisable  after the expiration of five years from
the date of grant.

     Restricted Stock

     Awards  of  restricted  stock  may be in  addition  to or in lieu of option
grants.  During the restriction  period, set by the Committee,  the recipient of
restricted  stock is not  permitted  to sell,  transfer,  pledge,  or assign the
shares.  Shares of  restricted  stock  become  free of all  restrictions  if the
recipient  dies or his or her  employment  is  terminated by reason of permanent
disability  during  the  restriction  period,  and  to  the  extent  set  by the
Committee,  if the recipient  retires under one of our retirement  plans. In the
event of a termination of employment during the restriction period for any other
reason,  all shares of restricted  stock will be forfeited and revert to MasTec,
except to the extent that the Committee  waives the  forfeiture  provision  with
respect to all or some of the restricted stock held by the former employee.

     The  recipient  of  restricted  stock is  entitled  to vote the  shares and
receive all dividends  paid  thereon,  except that  dividends  paid in shares of
Common Stock or other property will also be subject to the same  restrictions as
those placed on the restricted shares. Tax withholding obligations for any grant
of  restricted  stock  may be paid in  cash  by the  recipient  or may be met by
withholding  Common Stock  otherwise  deliverable  to the recipient  pursuant to
procedures approved by the Committee.

     In lieu of cash  bonuses  otherwise  payable to  eligible  employees  under
MasTec's  compensation  programs,  the Committee may determine that such bonuses
will be paid in Common Stock or partly in Common  Stock and partly in cash.  Any
shares of Common Stock paid as bonuses will be free of any restrictions  imposed
by the  plan.  MasTec  will  withhold  from any cash  bonuses  an amount of cash
sufficient to meet its tax withholding obligations with respect to both cash and
Common  Stock.  If the cash  portion  of the  bonus is not  sufficient,  the tax
withholding  obligations  must be paid in cash by the recipient or may be met by
the withholding of Common Stock otherwise  deliverable to the recipient pursuant
to procedures approved by the Committee.

     Change in Control; Recapitalization Provisions

     In the event of a "change in control" of MasTec,  in addition to any action
required  or  authorized  by the  option  or  award,  the  Committee  may in its
discretion  recommend  that the Board of  Directors  take  certain  actions as a
result of, or in  anticipation  of, the change in  control,  to assure  fair and
equitable  treatment  of the  employees  who hold options or  restricted  stock,
including  an offer to  purchase  any  outstanding  option or  restricted  stock
granted or issued  pursuant  to the Stock  Incentive  Plan for its cash value as
determined  by the  Committee.  However,  in no  event  may an  option  be  made
exercisable  prior to the expiration of six months from the date of grant or, in
the case of an  incentive  stock  option,  after  10 years  from the date it was
granted.

     A "Change in  control"  is  generally  defined  to include  (i) a merger or
consolidation  in which MasTec is not the surviving  corporation  or pursuant to
which any shares of MasTec are to be converted  into cash,  securities  or other
property,   or  any  sale,  lease,   exchange  or  other  transfer  of  all,  or
substantially  all,  of  the  assets  of  MasTec,   (ii)  the  approval  by  the
shareholders  of any plan for the  liquidation or  dissolution of MasTec,  (iii)
subject to certain limited exceptions, the acquisition by a "person" or "group,"
as defined in the Stock  Incentive  Plan,  of 33% or more of the Common Stock or
(iv) if individuals  constituting the "Incumbent Board," as defined in the Stock
Incentive Plan, cease to constitute a majority of our Board of Directors.

     Adjustments  will be made in the number and class of shares available under
the Stock  Incentive  Plan and the number,  class and price of shares subject to
outstanding option grants to reflect changes in the Common Stock through changes
in our corporate  structure or capitalization  such as through a merger or stock
split.

Federal Income Tax Consequences

     The following is a brief  description  of the material  federal  income tax
consequences,  under  existing law, to MasTec and recipients of awards under the
Stock Incentive Plan:

     Incentive Stock Options

o    Neither  the grant nor the  exercise  (while the  employee  is  employed or
     within three months after  termination of  employment,  or 12 months in the
     case of termination on account of disability) of an incentive  stock option
     will be treated as the  receipt of taxable  income by the  employee or as a
     deductible item by MasTec.  However the difference  between the fair market
     value of the option stock at exercise and the exercise  price is treated as
     an "item of adjustment" for alternative minimum tax purposes.  The basis of
     the incentive  stock option for  determining  gain or loss for  alternative
     minimum tax purposes  will be the exercise  price for the  incentive  stock
     option increased by the amount that the alternative  minimum tax income was
     increased due to the earlier exercise of the incentive stock option.

o    If the employee holds shares acquired by him or her upon the exercise of an
     incentive  option  for the  two-year  period  from the date of grant of the
     option and the one-year  period  beginning on the day after such  exercise,
     and if he or she has been an employee of MasTec or its  subsidiaries at all
     times from the date of grant to the day three months  before  exercise,  or
     twelve months in the case of termination on account of disability, then any
     gain  realized  by the  employee on a later sale or exchange of such shares
     will be a long-term capital gain and any loss sustained will be a long-term
     capital loss. MasTec will realize no tax deduction with respect to any such
     sale or exchange of option shares.

o    If the  employee  disposes of any shares  acquired  upon the exercise of an
     option  during the two-year  period from the date of grant of the option or
     the one-year period beginning on the day after such exercise,  the employee
     will  generally be  obligated to report as ordinary  income for the year in
     which the disposition occurred the amount by which the fair market value of
     such shares on the date of the  exercise  of the option  exceeds the option
     price,  and MasTec will be  entitled to a deduction  equal to the amount of
     such ordinary income. Any such ordinary income will increase the employee's
     tax basis for the  purpose of  determining  gain or loss.  If,  however,  a
     disposition  occurs  in the year in which  the  option  is  exercised,  the
     maximum amount that will be included as  alternative  minimum tax income is
     the gain on the  disposition  of the incentive  stock option stock.  Should
     there be a  disposition  in a year  other  than the year of  exercise,  the
     income on the  disposition  will not be considered  income for  alternative
     minimum tax purposes.

o    If an  option  holder  who has  acquired  stock  upon  the  exercise  of an
     incentive  stock option  makes a  disposition  within the  two-year  period
     described  above, and the disposition is a sale or exchange with respect to
     which a loss (if sustained) would be recognized to the option holder,  then
     the amount  includible in the option holder's gross income,  and the amount
     deductible  by  MasTec,  will not  exceed the excess (if any) of the amount
     realized on the sale or exchange over the tax basis of the stock.


     Non-Qualified Stock Options

     In the case of an option granted under the Stock Incentive Plan that is not
an incentive  stock  option,  the grant of the option will not result in taxable
income to the option  holder or a tax  deduction  to MasTec.  The option  holder
recognizes  ordinary income at the time the option is exercised in the amount by
which the fair market  value of the shares  acquired  exceeds the option  price.
MasTec is entitled to a  corresponding  ordinary  income tax  deduction  at that
time, if applicable income and social security tax withholding  requirements are
satisfied.  The option  holder's tax basis for purposes of  determining  gain or
loss on a  subsequent  sale of the shares is the fair market value of the shares
at the date of exercise of the option.  The holding  period for such shares will
commence on such date and, accordingly, will not include the period during which
the option was held. In the event of a sale of shares  received upon exercise of
the  option,  any gain or loss will  generally  be a capital  gain or loss.  The
capital gain or loss will be a long-term capital gain or loss if the shares were
held for more than one year after the date on which the option was exercised.

     Use of Stock to Exercise Options

     The payment of the option  exercise  price by delivery of Common Stock will
constitute  a  non-taxable  exchange  by the  optionee  and will not  affect the
incentive  stock option  status of the Common  Stock  acquired in the case of an
incentive  stock option.  However,  if the Common Stock delivered in payment was
previously  acquired  pursuant to the exercise of an incentive  stock option and
has not  been  held  for the  requisite  one-year  period,  the  exchange  would
constitute  a premature  disposition  of such Common  Stock for  purposes of the
incentive stock option holding  requirements.  Use of Common Stock in payment of
the option  price will result in the same tax  consequences  to MasTec as if the
exercise were effected by a cash payment.  The shares of stock received upon the
exercise of an  incentive or  non-qualified  stock option equal to the number of
shares used to  exercise  the option will have a basis in the stock equal to the
basis that the employee  had in the stock used in the  exercise.  The  remaining
shares of stock will have a basis equal to the gain,  if any, on the exercise of
the incentive or non-qualified stock option and any cash paid on the exercise.

     Stock Appreciation Rights

     The amount received by an optionee who exercises a stock appreciation right
with  respect to his or her option is taxable as ordinary  income at the time of
exercise  and  MasTec  is  entitled  to  a  corresponding  ordinary  income  tax
deduction.

     Bonus Stock

     The grantee will realize  ordinary income during his or her taxable year in
which the shares of Common Stock are issued pursuant to the award of bonus stock
in an amount equal to the fair market value of the shares of Common Stock at the
date of  issue.  MasTec is  entitled  to a  corresponding  ordinary  income  tax
deduction.  If the grantee  thereafter  disposes of such shares of Common Stock,
any amount  received in excess of the market  value of the shares on the date of
issue will be treated as long or  short-term  capital  gain  depending  upon the
holding period of the shares.

     Restricted Stock

     A grantee will not realize any taxable  income upon the award of restricted
stock unless a grantee  elects under Section 83(b) of the Internal  Revenue Code
(the  "Code")  to have the fair  market  value of the Common  Stock  (determined
without regard to the  possibility  of forfeiture)  included in his or her gross
income in the year the  restricted  stock is issued.  In the  absence of such an
election,  the grantee will realize  ordinary  income  during his or her taxable
year in which the possibility of forfeiture  lapses.  If the grantee  thereafter
disposes of the Common Stock,  any amount  received in excess of the fair market
value of the shares on the date the  possibility  of  forfeiture  lapsed will be
treated as long or short-term  gain depending upon the holding period  (measured
from the date the possibility of forfeiture  lapsed) of the shares.  MasTec will
be entitled to an ordinary tax deduction in the same amount and at the same time
the grantee is considered to have realized ordinary income.

     Change in Control

     Under certain circumstances,  accelerated vesting or exercise of options or
stock  appreciation   rights,  or  the  accelerated  lapse  of  restrictions  on
restricted  stock, in conjunction  with a "change in control" might be deemed an
"excess parachute payment" for purposes of the provisions of Section 280G of the
Code. To the extent it is so considered,  the optionee or grantee may be subject
to a 20% excise tax and MasTec may be denied a tax deduction.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

Report of the Compensation Committee

     The Compensation  Committee of the Board of Directors (the  "Committee") is
responsible  for  establishing  and  administering  the  policies  for  MasTec's
compensation   programs  and  for  approving  the  compensation  levels  of  the
executives and managers of MasTec,  including its Chief Executive  Officer.  The
Committee also reviews with the Chief Executive Officer  guidelines for salaries
and bonus awards applicable to MasTec's  employees other than its executives and
managers. The Committee is composed of Arthur B. Laffer, who serves as Chairman,
and Olaf  Olafsson,  William N.  Shiebler and Jose S.  Sorzano,  all of whom are
non-employee directors of MasTec.

Statement of Philosophy of Executive Compensation

     The  executive  compensation  program of MasTec is  designed to (i) provide
base  compensation  reasonably  comparable  to that  offered  by  other  leading
companies to their  executives and managers so as to attract and retain talented
personnel,  (ii) motivate executives and managers to achieve the strategic goals
set by MasTec by linking an executive's or a manager's incentive compensation to
the  performance  of  MasTec  and  applicable  business  units,  as  well  as to
individual performance, and (iii) align the interests of MasTec's executives and
managers with the long-term  interests of its shareholders  through the award of
stock options and other  stock-related  programs.  To implement this philosophy,
MasTec offers its executives and managers  compensation  packages that include a
mix of salary, incentive bonus awards, and stock options.

     In determining  the level and form of executive  compensation to be paid or
awarded,  the Committee  relies primarily on MasTec's results of operations and,
in the case of senior executives,  an assessment of MasTec's overall performance
in light of its  strategic  objectives.  The  Committee  considered  a number of
factors in establishing 1999 compensation, none of which were quantified, ranked
or assigned relative weights.

     o    The  substantial  increase in revenue and  earnings in  comparison  to
          prior years.

     o    The substantial increase in MasTec's stock price from prior years.

     o    The  significant  consolidation  and  reorganization  of MasTec's core
          North  American  infrastructure  service  business into more efficient
          service lines organized by customer groups.

     o    The further  diversification  and  expansion of MasTec's core business
          through fold-in acquisitions.

     o    The continued  divestiture of non-core assets to concentrate resources
          on MasTec's core business.

     o    Individual performance

Salary

     The base salary of  executives  and  managers is  determined  initially  by
analyzing and evaluating the  responsibilities of the position and comparing the
proposed  base  salary  with  that of  executives  and  managers  in  comparable
positions in other  companies.  Adjustments are determined by objective  factors
such  as  MasTec's  performance  and  the  individual's   contribution  to  that
performance and subjective  considerations  such as additional  responsibilities
taken on by the executive or manager for 1999. The Committee  awarded  increases
in base  salary to certain of the  executive  officers  and  managers of MasTec,
including certain of the Named Executive  Officers  identified under the caption
"Executive Compensation" below.

Incentive Awards

     In addition to paying a base salary,  MasTec awards incentive  bonuses as a
component  of overall  compensation.  MasTec has  established  formal  incentive
compensation  plans  for  our  senior  executives  at  both  the  corporate  and
operational  levels  that  awards  incentive  bonuses  based on  MasTec's  or an
individual unit's  performance as measured by earnings before interest and taxes
("EBIT") and return on assets.  Awards are based on a multiple of base salary or
a  percentage  of EBIT.  A portion  of the bonus is  awarded  in stock and stock
options.  MasTec or the  individual  unit must meet certain  minimum  thresholds
before any bonus is earned.  For 1999, the Committee awarded bonuses,  including
restricted  stock and stock  options,  to certain  of  MasTec's  executives  and
managers, including the Named Executive Officers, under these plans.

CEO Compensation

     Pursuant to our existing  employment  agreement with Joel-Tomas Citron, our
President and Chief Executive Officer,  MasTec was obligated to pay Mr. Citron a
bonus of $600,000 upon the achievement of a certain stock price level, which was
achieved.  Additionally,  due  to  MasTec's  strong  performance  in  1999,  the
Committee awarded Mr. Citron an additional bonus of $400,000, a portion of which
was paid in Common  Stock.  The  Committee  also awarded Mr.  Citron  options to
purchase  300,000  shares of Common Stock at an exercise price equal to the fair
market value of the Common Stock on the date of grant.

     During a portion of 1999, Jorge Mas served as President and Chief Executive
Officer of MasTec.  For his  services  in 1999 and prior  years,  the  Committee
granted Mr. Mas  options or stock  appreciation  rights with  respect to 500,000
shares of Common  Stock at an exercise  price equal to the fair market  value of
the Common Stock on the date of grant. Mr. Mas continues to serve as Chairman of
the Board of Directors, but is no longer an executive officer of MasTec.

     Stock granted to employees for 1999.

(2)  All options  were  granted at an exercise  price equal to fair market value
     based on the mean  between the high and low sale prices of the Common Stock
     on the New York Stock Exchange on the date of grant.

(3)  Potential gains are net of exercise price, but before taxes associated with
     exercise.  These amounts  represent  certain  assumed rates of appreciation
     only,  based  on  Securities  and  Exchange  Commission  rules,  and do not
     represent MasTec's estimate or projection of the price of MasTec's stock in
     the future. Actual gains, if any, on stock option exercises depend upon the
     actual  future  performance  of  MasTec's  Common  Stock and the  continued
     employment  of  the  option   holders   throughout   the  vesting   period.
     Accordingly,  the potential  realizable  values set forth in this table may
     not be achieved or may be exceeded.

Performance Table

     The following  table compares the cumulative  total  shareholder  return on
MasTec's Common Stock from December 31, 1994 through  December 31, 1999 with the
cumulative  total return of the S & P 500 Stock Index and a  company-constructed
index of (a) seven peer  companies  consisting  of Able  Telcom  Holding  Corp.,
Amerilink Corp.,  Arguss Holdings,  Inc. Dycom Industries,  Inc.,  International
Fibercom,  Inc.  MYR Group,  Inc.,  and Quanta  Services,  Inc.,  (the "Old Peer
Group"),  and (b) eight peer companies  consisting of Able Telecom Holding Corp,
Arguss Holdings,  Inc., Black Box Corp., Dycom Industries,  Inc.,  International
Fibercom,  Inc., LCC  International  Inc.,  Quanta Services,  Inc., and Wireless
Facilities Inc., (the "New Peer Group"). The table assumes that the value of the
investment  in the  Common  Stock  was $100 on  December  31,  1994 and that all
dividends were  reinvested.  This data is not  necessarily  indicative of future
results.  The change in the  composition  of the peer  group is to  include  new
public  companies that qualify as industry  peers,  to delete certain  companies
that are no longer public,  and to achieve a more  representative  comparison of
performance.

December 31, 1999, the indebtedness of Jorge Mas was paid in full.

     MasTec purchases and leases equipment from a company in which Jorge Mas has
a significant  interest.  MasTec believes the value of these transactions is not
material.

                              SELECTION OF AUDITORS

     PricewaterhouseCoopers  LLP was  appointed  by the  Board of  Directors  of
MasTec to audit MasTec's financial  statements for 1999.  PricewaterhouseCoopers
LLP  has  acted  as  independent  public  accountants  for  MasTec  since  1995.
Representatives  of  PricewaterhouseCoopers  LLP will be  present  at the Annual
Meeting, will have an opportunity to make a statement if they so desire and will
be available to respond to appropriate questions from shareholders.

                                  MISCELLANEOUS

     A list of MasTec's  shareholders  as of March 21, 2000, the record date for
the  Annual  Meeting,   will  be  available  for  inspection  at  our  corporate
headquarters  located at 3155 N.W. 77th Avenue,  Miami,  Florida,  during normal
business hours during the 10 day period prior to the Annual Meeting.

     Solicitation  of proxies  will be made  initially by mail.  Our  directors,
officers  and  employees  also may  solicit  proxies  in person or by  telephone
without  additional  compensation.  In  addition,  proxies may be  solicited  by
certain banking institutions,  brokerage firms, custodians,  trustees,  nominees
and  fiduciaries  who will mail  material to or otherwise  communicate  with the
beneficial  owners of shares of MasTec's  Common Stock.  In addition,  Corporate

solicitors and will be paid $4,000.  The cost of this solicitation will be borne
by MasTec.

     Pursuant  to Rule 14a-8 under the  Securities  Exchange  Act of 1934,  if a
shareholder  notifies  MasTec after December 15, 2000, of an intent to present a
proposal at MasTec's  annual meeting of  shareholders  in the year 2001 (and for
any reason the proposal is voted upon at that Annual  Meeting),  MasTec's  proxy
holders  will have the right to exercise  discretionary  voting  authority  with
respect  to the  proposal,  if  presented  at  the  meeting,  without  including
information  regarding the proposal in our proxy  materials.  Any proposal of an
eligible  shareholder  intended  to  be  presented  at  the  annual  meeting  of
shareholders  of MasTec in 2001 must be received by MasTec by February  25, 2001
to be eligible  for  inclusion  in MasTec's  proxy  statement  and form of proxy
relating to that annual meeting.

     The Board of  Directors  does not intend to present  and knows of no others
who intend to present at the Annual  Meeting any matter or  business  other than
that set forth in the accompanying Notice of Annual Meeting of Shareholders.  If
other  matters  are  properly  brought  before  the  Annual  Meeting,  it is the
intention  of the persons  named in the  accompanying  form of proxy to vote any
proxies on such matters in accordance with their judgment.

1999 is being  mailed with this Proxy  Statement  to  shareholders  of record on
or about April 5, 2000.

                                  EXHIBIT "B"

                                  MASTEC, INC.
                            1994 STOCK INCENTIVE PLAN

                            (As Amended May 17, 2000)


1.   Purpose.  The purpose of the MasTec,  Inc. 1994 Stock  Incentive  Plan (the
     "Plan") is to increase the interest of the  executives,  managers and other
     key employees of MasTec,  Inc. and its  subsidiaries  in MasTec's  business
     through the added incentive  created by the opportunity  afforded for stock
     ownership under the Plan. Stock ownership will provide these employees with
     a further  stake in the  future  welfare of MasTec  and  encourage  them to
     remain with MasTec and its subsidiaries.  It is also expected that the Plan
     will encourage  qualified persons to seek and accept employment with MasTec
     and its  subsidiaries.  Pursuant to the Plan,  eligible  employees  will be
     offered the  opportunity to acquire  MasTec common stock  ("Common  Stock")
     through the grant of options, the award of restricted stock under the Plan,
     bonuses  payable in stock or a combination  thereof.  As used in this Plan,
     the term "subsidiary"  means any present or future  corporation which is or
     would be a  "subsidiary  corporation"  of MasTec as the term is  defined in
     Section 424(f) of the Internal Revenue Code of 1986 (the "Code").

2.   Administration of the Plan.

     (a)  Committee.  The Plan will be administered by the Board of Directors of
          MasTec (the "Board").  The Board,  however,  may at any time appoint a
          committee (the  "Committee") of two or more Board members and delegate
          to such Committee one or more of the  administrative  powers allocated
          to the Board  pursuant to the  provisions of the Plan.  Members of the
          Committee  will  serve  for  such  period  of  time as the  Board  may
          determine and will be subject to removal by the Board at any time. The
          Board may also at any time  terminate  the  functions of the Committee
          and  reassume  all powers and  authority  previously  delegated to the
          Committee.

     (b)  Powers of the Board.  Subject to the provisions of the Plan, the Board
          of Directors will have the authority, in its discretion:  (i) to grant
          awards of stock  options,  restricted  stock,  stock  bonuses or other
          awards  pursuant to the terms of the Plan;  (ii) to determine the fair
          market  value of the Common Stock of MasTec;  (iii) to  determine  the
          exercise  price per share of options to be granted;  (iv) to determine
          the persons to whom, and the time or times at which,  options or other
          awards will be granted and the number of shares to be  represented  by
          each option or award; (v) to determine the vesting schedule of options
          to be  granted;  (vi)  to  prescribe,  amend  and  rescind  rules  and
          regulations  relating to the Plan;  (vii) to  determine  the terms and
          provisions  of each award  granted  under the Plan  (which need not be
          identical)   including,   without   limitation,   those   relating  to
          forfeiture,  payment  and  exercisability;  (viii) to  accelerate  the
          vesting date of any award;  (ix) to authorize any person to execute on
          behalf of MasTec any instrument required to effectuate the grant of an
          award  previously  granted by the Board; (x) subject to the provisions
          of  the  Plan  and  subject  to  such   additional   limitations   and
          restrictions as the Board may impose,  to delegate to specific members
          of management or to a committee of management  personnel the authority
          to  determine:  (A) the  persons  to whom,  and the time and  times at
          which,  awards  will  be  granted  and  the  number  of  shares  to be
          represented  by each  option or award;  (B) the  vesting  schedule  of
          options; (C) the term of awards; and (D) other terms and conditions of
          any  options  or  awards,  provided  that the Board  will not have the
          authority  to  delegate  such  matters  with  respect  to awards to be
          granted  to any  person  ("Insiders")  subject  to  Section  16 of the
          Securities  Exchange Act of 1934 (the "Exchange  Act") or any "covered
          employee"  under Section 162(m) of the Code; and (xi) to interpret the
          Plan and make all other  determinations  deemed necessary or advisable
          for  the  administration  of the  Plan.  The  Board  may  require  the
          voluntary  surrender of all or any portion of any option granted under
          the Plan as a condition  precedent  to a grant of a new option to such
          optionee.  Subject to the provisions of the Plan, such new option will
          be exercisable at the price, during the period and on such other terms
          and  conditions  as are  specified  by the  Board  at the time the new
          option is granted.  Upon surrender,  the options  surrendered  will be
          unexercisable and the shares  previously  subject to such options will
          be available for the grant of other options.

     (c)  Effect of the Board's  Decision.  All  decisions,  determinations  and
          interpretations of the Board of Directors will be final and binding on
          all employees of MasTec and its subsidiaries participating or eligible
          to participate in the Plan.

3.   Agreements. Each option or stock or other awards granted pursuant to the
     Plan will be  evidenced  by an Option  Agreement  or Award  Agreement  (the
     "Agreement").  The Agreement will not be a precondition  to the granting of
     options or stock or other awards;  however,  no person will have any rights
     under any option or stock or other awards granted under the Plan unless and
     until the  optionee  to whom such  option or stock or other  award has been
     granted has executed and delivered to MasTec an  Agreement.  The Board will
     prescribe  the form of all  Agreements.  A fully  executed  original of the
     Agreement will be provided to both MasTec and the optionee.

4.   Compliance  with Rule 16b-3.  It is the intent of MasTec that this Plan
     and options,  stock and other awards hereunder satisfy,  and be interpreted
     in a manner that,  in the case of employees who have been granted an option
     or  awarded  stock  under  the  Plan  ("Participants")  who  are  or may be
     Insiders,  satisfies  the  applicable  requirements  of Rule  16b-3  of the
     Exchange Act, so that such persons will be entitled to the benefits of Rule
     16b-3, or other exemptive rules under Section 16, and will not be subjected
     to avoidable liability thereunder.  If any provision of this Plan or of any
     option, stock or other award would otherwise frustrate or conflict with the
     intent  expressed in this Section 4, that provision to the extent  possible
     will be interpreted and deemed amended so as to avoid such conflict. To the
     extent of any  remaining  irreconcilable  conflict  with such intent,  such
     provision will be deemed void as applicable to Insiders.

5.   Shares of Stock Subject to the Plan. The total number of shares that may
     be optioned or awarded under the Plan is 3,500,000  shares of the $0.10 par
     value Common Stock of MasTec (the "Common Stock") of which 1,000,000 shares
     may be awarded as  restricted  stock,  subject to adjustment as provided in
     Paragraph 5. No employee will receive, over the term of the Plan, awards in
     the form of options,  whether incentive stock options or options other than
     incentive stock options,  to purchase more than 1,000,000  shares of Common
     Stock.  Any shares  subject to an option which for any reason expires or is
     terminated  unexercised  and any  restricted  stock which is forfeited  may
     again be  optioned  or  awarded  under the Plan;  provided,  however,  that
     forfeited  shares will not be available for further  awards if the employee
     has realized any benefits of ownership from such shares.  Shares subject to
     the Plan may be either  authorized  and  unissued  shares or issued  shares
     acquired by MasTec or its subsidiaries.

6.   Eligibility. Key employees, including executives and managers, of MasTec
     and its subsidiaries (but excluding non-employee directors) are eligible to
     be granted options and awarded  restricted stock under the Plan and to have
     their bonuses  payable in stock.  The employees who will receive  awards or
     options under the Plan will be selected from time to time by the Board,  in
     its sole  discretion,  from among those  eligible,  which may be based upon
     information  furnished to the Board by MasTec's  management,  and the Board
     will determine, in its sole discretion,  the number of shares to be covered
     by the award or awards and by the  option or  options  granted to each such
     employee selected.

7.   Duration of the Plan.  No award or option may be granted under the Plan
     after  January  31,  2004,  but awards or options  theretofore  granted may
     extend beyond that date.
<PAGE>

8.   Terms and  Conditions of Stock Options.  All options  granted under this
     Plan will be either  incentive stock options,  as defined in Section 422 of
     the Code, or options other than incentive  stock options.  Each such option
     will be subject to all the applicable provisions of the Plan, including the
     following terms and conditions,  and to such other terms and conditions not
     inconsistent with the Plan as the Board may determine.


     (a)  The  option  price  per share  will be  determined  by the  Board.
          However,  subject to  Paragraph  8(k),  the option  price of incentive
          stock options will not be less than 100% of the fair market value of a
          share of Common Stock at the time the option is granted.  For purposes
          of the  Plan,  the fair  market  value  will be the mean  between  the
          highest and lowest sale prices at which the Common  Stock is traded on
          the New York Stock  Exchange  on the  relevant  date.  If no sales are
          available  on such date,  the most recent  date,  within a  reasonable
          time, on which sales are  available  will be used. If the Common Stock
          is listed on a national  securities  exchange  other than the New York
          Stock Exchange, the mean between the highest and lowest sale prices at
          which the Common Stock is traded on such exchange on such date will be
          used.  If there is no sale of the Common Stock on such exchange on the
          date the option is granted,  the mean between the bid and asked prices
          on such  exchange  at the  close of the  market  on such  date will be
          deemed to be the fair market value of the Common Stock.  If the Common
          Stock is quoted in the  over-the-counter  market on the relevant date,
          the fair market  value will be the mean between the highest and lowest
          sale   prices   at  which   the   Common   Stock  is   quoted  in  the
          over-the-counter market on the relevant date as reported on NASDAQ.

     (b)  Each incentive  stock option will be  exercisable  during and over
          such period ending not later than 10 years,  or such later date as may
          be allowable under the Code,  from the date it was granted,  as may be
          determined by the Board and stated in the Agreement. Each other option
          will be  exercisable  during and over such period as may be determined
          by the Board and stated in the Agreement.

     (c)  An option will not be exercisable with respect to a fractional share
          of Common  Stock or with respect to the lesser of fifty (50) shares or
          the full number of shares then  subject to the option.  No  fractional
          shares of Common  Stock will be issued upon the exercise of an option.
          If a fractional share of Common Stock will become subject to an option
          by reason of a stock  dividend or otherwise,  the optionee will not be
          entitled to exercise the option with respect to such fractional share.

     (d)  Each  option  will state  whether it will or will not be treated as an
          incentive stock option.

     (e)  Each  option  may be  exercised  by  giving  written  notice to MasTec
          specifying  the  number  of  shares  to be  purchased,  which  will be
          accompanied by payment in full  including  applicable  taxes,  if any.
          Payment, except as provided in the Agreement, will be

          (A)  in United States dollars by check or bank draft, or

          (B)  by tendering to MasTec  Common Stock shares  already owned by the
               person  exercising the option,  which may include shares received
               as the result of a prior  exercise  of the  option,  and having a
               fair market value,  as determined in Paragraph  8(a), on the date
               on which the option is exercised equal to the cash exercise price
               applicable to such option.

          (C)  by a combination of United States dollars and Common Stock shares
               as aforesaid, or

          (D)  in accordance with a cashless exercise program under which, if so
               instructed by the optionee,  shares of Common Stock may be issued
               directly to the  optionee's  broker or dealer upon receipt of the
               purchase price in cash from the broker or dealer.

     No  optionee  will  have any  rights  to  dividends  or other  rights  of a
shareholder  with respect to shares of Common Stock subject to his or her option
until he or she has given  written  notice of  exercise of his or her option and
paid in full for such shares.
<PAGE>

     (f)  Notwithstanding the foregoing,  the Board may, in its sole discretion,
          grant to a grantee of an option the right (hereinafter  referred to as
          a "stock appreciation right") to elect, in the manner described below,
          in lieu of  exercising  his or her  option for all or a portion of the
          shares of Common Stock covered by such option,  to  relinquish  his or
          her option  with  respect to any or all of such  shares and to receive
          from MasTec a payment  having a value equal to the amount by which (a)
          the fair market value,  as determined in Paragraph 8(a), of a share of
          Common Stock on the date of such election, multiplied by the number of
          shares as to which the grantee will have made such  election,  exceeds
          (b) the total purchase price for that number of shares of Common Stock
          under the terms of such  option.  A grantee who makes such an election
          will receive  payment in the sole  discretion of the Board (i) in cash
          equal to such excess; or (ii) in the nearest whole number of shares of
          Common Stock of MasTec having an aggregate  value which is not greater
          than the cash amount  calculated in (i) above;  or (iii) a combination
          of (i) and (ii) above.  A stock  appreciation  right may be  exercised
          only  when the  amount  described  in (a)  above  exceeds  the  amount
          described  in (b) above.  An election to exercise  stock  appreciation
          rights will be deemed to have been made on the day  written  notice of
          such election, addressed to the Board (Attention: Corporate Secretary)
          is received at MasTec's  executive  offices.  An option or any portion
          thereof  with  respect to which a grantee has elected to exercise  the
          stock  appreciation  rights  described  above will be  surrendered  to
          MasTec and such option will thereafter remain exercisable according to
          its terms  only with  respect  to the  number of shares as to which it
          would otherwise be exercisable, less the number of shares with respect
          to which stock appreciation rights have been exercised. The grant of a
          stock  appreciation  right will be evidenced by such form of Agreement
          as  the  Board  may   prescribe.   The  Agreement   evidencing   stock
          appreciation  rights will be personal  and will provide that they will
          not be transferable by the grantee  otherwise than by will or the laws
          of descent and distribution and that they will be exercisable,  during
          the lifetime of the grantee, only by him or her.

     (g)  An option  may be  exercised  only if at all times  during  the period
          beginning  with the date of the  granting  of the option and ending on
          the date of such  exercise,  the  grantee  was an  employee  of either
          MasTec or of a subsidiary of MasTec or of another corporation referred
          to in Section  421(a)(2) of the Code,  except that if such  continuous
          employment  is terminated  by  retirement  under a retirement  plan of
          MasTec or a subsidiary,  or because of death or permanent  disability,
          the  option may be  exercised  within a period to be  provided  in the
          Agreement  with  the  grantee  not  to  exceed  one  year  after  such
          termination of continuous  employment,  but in no event later than the
          termination date of the option. The Board may require medical evidence
          of permanent disability,  including medical examinations by physicians
          selected by it.  Except as described in this  Paragraph  8(g),  unless
          otherwise  provided  in  the  Agreement,  all  options  granted  to an
          optionee and not previously  exercised will terminate upon termination
          of employment.

     (h)  The option by its terms will be personal and will not be  transferable
          by the optionee  otherwise  than by will or by the laws of descent and
          distribution.  During the lifetime of an optionee,  the option will be
          exercisable only by the optionee. In the event any option is exercised
          by the executors,  administrators, heirs or distributees of the estate
          of a deceased  optionee,  MasTec will be under no  obligation to issue
          Common Stock  unless and until MasTec is satisfied  that the person or
          persons   exercising   the  option  are  the  duly   appointed   legal
          representative  of  the  deceased  optionee's  estate  or  the  proper
          legatees or distributees.

     (i)  Notwithstanding any intent to grant incentive stock options, an option
          granted will not be considered an incentive stock option to the extent
          that it together with any earlier  incentive stock options permits the
          exercise for the first time in any calendar year of more than $100,000
          in value of Common Stock (determined at the time of grant).

     (j)  The  Board  may,  but need not,  require  such  consideration  from an
          optionee  at the time of  granting  an  option  as it will  determine,
          either  in  lieu  of,  or  in   addition   to,  the   limitations   on
          exercisability provided in Paragraph 8(g).

     (k)  No  incentive  stock option will be granted to an employee who owns or
          would own  immediately  before the grant of such  option,  directly or
          indirectly,  stock  possessing  more  than 10% of the  total  combined
          voting power of all classes of stock of MasTec.  This restriction does
          not apply if, at the time such incentive stock option is granted,  the
          option price is at least 110% of the fair market value of one share of
          Common Stock,  as  determined in Paragraph  8(a), on the date of grant
          and the incentive stock option by its terms is not  exercisable  after
          the expiration of five years from the date of grant.

9.   Terms and Conditions of Restricted  Stock Awards.  All awards of restricted
     stock under the Plan will be subject to all the  applicable  provisions  of
     the Plan,  including the following terms and conditions,  and to such other
     terms  and  conditions  not  inconsistent   therewith,  as  the  Board  may
     determine.

     (a)  Awards of restricted  stock may be in addition to or in lieu of option
          grants.

     (b)  During  a  period  set by the  Board  at the  time  of each  award  of
          restricted stock (the "restriction period"), the recipient will not be
          permitted  to  sell,  transfer,   pledge,  or  assign  the  shares  of
          restricted  stock;  except that such shares may be used,  if the award
          permits,  to pay the option price of any option granted under the Plan
          provided an equal number of shares delivered to the optionee carry the
          same restrictions as the shares so used.

     (c)  Shares of restricted stock will become free of all restrictions if the
          recipient  dies or his  employment  terminates  by reason of permanent
          disability,  as determined by the Board, during the restriction period
          and, to the extent set by the Board at the time of the award or later,
          if the  recipient  retires  under a  retirement  plan of  MasTec  or a
          subsidiary during such period.  The Board may require medical evidence
          of permanent disability,  including medical examinations by physicians
          selected by it. If the Board determines that any such recipient is not
          permanently  disabled or that a retiree's  restricted  stock is not to
          become free of restrictions,  the restricted stock held by either such
          recipient, as the case may be, will be forfeited and revert to MasTec.

     (d)  Shares of restricted stock will be forfeited and revert to MasTec upon
          the  recipient's  termination  of  employment  during the  restriction
          period for any reason other than death,  permanent  disability  or, to
          the extent determined by the Board, retirement under a retirement plan
          of MasTec or a subsidiary, except to the extent the Board, in its sole
          discretion,  finds  that  such  forfeiture  might  not be in the  best
          interest  of  MasTec  and,  therefore,  waives  all  or  part  of  the
          application  of this  provision to the  restricted  stock held by such
          recipient.

     (e)  Stock certificates for restricted stock will be registered in the name
          of the  recipient but will be  appropriately  legended and returned to
          MasTec by the  recipient,  together  with a stock  power,  endorsed in
          blank by the recipient.  The recipient will be entitled to vote shares
          of  restricted  stock  and  will be  entitled  to all  dividends  paid
          thereon,  except that dividends paid in Common Stock or other property
          will also be subject to the same restrictions.

     (f)  Restricted stock will become free of the foregoing  restrictions  upon
          expiration  of the  applicable  restriction  period  and  MasTec  will
          deliver Common Stock  certificates  evidencing  such stock free of any
          restrictive legend.

10.  Bonuses Payable in Stock. In lieu of cash bonuses  otherwise  payable under
     MasTec's   compensation   plans  or  practices  to  employees  eligible  to
     participate in the Plan, the Board, in its sole  discretion,  may determine
     that such  bonuses may be payable in stock or partly in stock and partly in
     cash.  Such  bonuses  will  be  in  consideration  of  services  previously
     performed  and as an incentive  toward  future  services and may consist of
     shares of Common  Stock with or without  restriction  on future  sale.  The
     number of shares of Common Stock payable in lieu of an amount of each bonus
     otherwise  payable will be  determined  by dividing such amount by the fair
     market  value of one  share of  Common  Stock on a date  determined  by the
     Board, with fair market value determined as of such date in accordance with
     Paragraph 8(a).

11.  Change in Control.

     (a) In the event of a change in  control  of  MasTec,  in  addition  to any
action  required or authorized  by the terms of an Agreement,  the Board may, in
its sole  discretion,  take any of the  following  actions  as a  result,  or in
anticipation,  of any such  event to  assure  fair and  equitable  treatment  of
Participants:

          (i)  accelerate  time periods for purposes of vesting in, or realizing
               gain from, any outstanding  option or shares of restricted  stock
               made pursuant to this Plan;

          (ii) offer to purchase any outstanding  option or shares of restricted
               stock  made  pursuant  to  this  Plan  from  the  holder  for its
               equivalent  cash value, as determined by the Board as of the date
               of the change in control; or

          (iii)make adjustments or modifications to outstanding  options or with
               respect to  restricted  stock as the Board deems  appropriate  to
               maintain and protect the rights and interests of the Participants
               following such change in control.

Any such action will be conclusive and binding on MasTec and all Participants.

     (b)  For purposes of this Section 11, a "change in control"  will be deemed
          to have occurred if at any time:

          (1)  there is consummated

               (i)  any consolidation or merger of MasTec in which MasTec is not
                    the continuing or surviving corporation or pursuant to which
                    any 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

               (ii) 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

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

          (3)  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 March 1, 1994,  owned  greater  than 20% of the  combined
               voting power of such Common Stock, or (iii) a trust,  foundation,
               partnership  or  other  entity  controlled  by an  individual  or
               individuals described in Paragraph 11(b)(3)(ii); or

          (4)  individuals  who  constitute  the  Board on March  1,  1994  (the
               "Incumbent Board"), cease for any reason to constitute at least a
               majority  thereof,  provided that any person  becoming a director
               subsequent to March 1, 1994,  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  (4),  considered  as though such Person
               were a member of the Incumbent Board.

     (c)  In no event,  however,  may any  incentive  stock  option be exercised
          after 10 years from the date it was granted.
<PAGE>

12.  Transfer,  Leave of Absence. For the purpose of the Plan: (a) a transfer of
     an employee from MasTec to a subsidiary or affiliate of MasTec,  whether or
     not  incorporated,  or vice versa,  or from one  subsidiary or affiliate of
     MasTec to another,  and (b) a leave of absence,  duly authorized in writing
     by MasTec or a  subsidiary  or  affiliate  of MasTec,  will not be deemed a
     termination of employment.

13.  Rights of Employees.

     (a)  No person  will have any  rights  or claims  under the Plan  except in
          accordance with the provisions of the Plan and any agreement.

     (b)  Nothing  contained in the Plan will be deemed to give any employee the
          right to be retained in the service of MasTec or its subsidiaries.

14.  Tax Withholding Obligations.

     (a)  The payment of taxes,  if any, upon the exercise of an option pursuant
          to Paragraph 8(e) or a stock  appreciation right pursuant to Paragraph
          8(f), will be in cash at the time of exercise or on the applicable tax
          date under Section 83 of the Code, if later;  provided,  however,  tax
          withholding  obligations may be met by the withholding of Common Stock
          otherwise  deliverable to the optionee pursuant to procedures approved
          by the Board.

     (b)  Recipients  of  restricted  stock  pursuant  to  paragraph  9 will  be
          required to pay taxes to MasTec  upon the  expiration  of  restriction
          periods or such earlier dates as elected pursuant to Section 83 of the
          Code; provided, however, tax withholding obligations may be met by the
          withholding  of Common Stock  otherwise  deliverable  to the recipient
          pursuant to procedures  approved by the Board. In no event will Common
          Stock be delivered to any awardee  until he has paid to MasTec in cash
          the amount of tax  required to be withheld by MasTec or has elected to
          have his  withholding  obligations  met by the  withholding  of Common
          stock in  accordance  with the  procedures  approved  by the  Board or
          otherwise  entered into an agreement  satisfactory to MasTec providing
          for payment of withholding tax.

     (c)  MasTec will withhold from any cash bonus described in Paragraph 10, an
          amount of cash sufficient to meet its tax withholding obligations.

15.  Changes in Capital.  Upon changes in the outstanding Common Stock by reason
     of  a  stock   dividend,   stock   split,   reverse   split,   subdivision,
     recapitalization,  merger,  consolidation  (whether  or  not  MasTec  is  a
     surviving  corporation),  an  extraordinary  dividend  payable  in  cash or
     property, combination or exchange of shares, separation,  reorganization or
     liquidation,  the aggregate  number and class of shares available under the
     Plan as to which stock  options and  restricted  stock may be awarded,  the
     number and class of shares under each option and the option price per share
     will be correspondingly  adjusted by the Board, such adjustments to be made
     in the case of  outstanding  options  without  change  in the  total  price
     applicable to such options.

16.  Miscellaneous Provisions.

     (a)  The Plan will be  unfunded.  MasTec will not be required to  establish
          any  special  or  separate  fund or to make any other  segregation  of
          assets to assure the  issuance of shares  upon  exercise of any option
          under the Plan and issuance of shares upon exercise of options will be
          subordinate to the claims of MasTec's general creditors. Proceeds from
          the sale of shares of Common Stock  pursuant to options  granted under
          this Plan will constitute general funds of MasTec. The expenses of the
          Plan will be borne by MasTec.

     (b)  It is understood that the Board may, at any time and from time to time
          after the  granting of an option or the award of  restricted  stock or
          bonuses  payable in Common Stock  hereunder,  specify such  additional
          terms,  conditions  and  restrictions  with  respect to such option or
          stock as may be deemed  necessary or appropriate to ensure  compliance
          with any and all  applicable  laws,  including,  but not  limited  to,
          terms,  restrictions  and conditions  for compliance  with federal and
          state  securities laws and methods of withholding or providing for the
          payment of required taxes.

     (c)  If at any time the Board will determine,  in its discretion,  that the
          listing,  registration or qualification of shares of Common Stock upon
          any national securities exchange or under any state or federal law, or
          the  consent or  approval  of any  governmental  regulatory  body,  is
          necessary or desirable as a condition of, or in connection  with,  the
          sale or purchase  of shares of Common  Stock  hereunder,  no option or
          stock appreciation right may be exercised or restricted stock or stock
          bonus may be  transferred  in whole or in part  unless  and until such
          listing,  registration,  qualification,  consent or approval will have
          been  effected or obtained,  or otherwise  provided  for,  free of any
          conditions  not  acceptable  to  the  Board  in  the  exercise  of its
          reasonable judgment.

     (d)  By accepting any benefit  under the Plan,  each  Participant  and each
          person  claiming  under or through  such person  will be  conclusively
          deemed to have indicated his acceptance and ratification,  and consent
          to, any action taken under the Plan by the Board MasTec or the Board.

     (e)  The Plan will be governed by and construed in accordance with the laws
          of the State of Florida.

17.  Limits of Liability.

     (a)  Any liability of MasTec or a subsidiary  of MasTec to any  Participant
          with respect to an option or stock or other award will be based solely
          upon contractual obligations created by the Plan and the Agreement.

     (b)  Neither  MasTec  nor a  subsidiary  of  MasTec,  nor any member of the
          Board, nor any other person  participating in any determination of any
          question under the Plan, or in the  interpretation,  administration or
          application of the Plan,  will have any liability to any party for any
          action taken or not taken in connection  with the Plan,  except as may
          expressly be provided by statute.

18.  Amendments.  The Board may amend,  alter or  discontinue  the Plan,  at any
     time,  including without limitation  amendments necessary to qualify for an
     exemption  or to  comply  with  applicable  law or  regulations,  provided,
     however,  no amendment,  alteration or  discontinuation  will be made which
     would  impair the rights of any holder of an award of  restricted  stock or
     option or stock  bonus  theretofore  granted,  without  his or her  written
     consent, or which, without the approval of MasTec"s shareholders, would:

     (a)  except as is provided in Paragraph 15,  increase the maximum number of
          shares of Common Stock reserved for the purpose of the Plan;

     (b)  except as is provided in Paragraphs 8(f) and 15 of the Plan,  decrease
          the option price of an incentive stock option to less than 100% of the
          fair market  value,  as  determined  in Paragraph  8(a), of a share of
          Common Stock on the date of the granting of the option;

     (c)  change the class of persons eligible to receive an award of restricted
          stock or options under the Plan; or

     (d) extend the duration of the Plan.

     The Board may  amend the terms of any award of  restricted  stock or option
theretofore granted, retroactively or prospectively,  but no such amendment will
impair the rights of any holder without his or her written consent.

19.  Duration.  The Plan will terminate upon the earlier of the following  dates
     or events to occur:

     (a)  upon the adoption of a resolution of the Board  terminating  the Plan;
          or

     (b)  January 31, 2004.

     No such  termination of the Plan will affect the rights of any  Participant
hereunder  and all options  previously  granted and  restricted  stock and stock
bonus  awarded  hereunder  will  continue  in force and in  operation  after the
termination  of the  Plan,  except  as  they  may  be  otherwise  terminated  in
accordance with the terms of the Plan.
