Supplemental disclosure of non-cash investing and financing
activities:

     During the three months ended March 31, 2001, we completed
certain acquisitions which have been accounted for as purchases.
The fair value of the net assets excluding goodwill acquired
totaled $1.9 million and was comprised primarily of $2.6 million
of accounts receivable, $1.7 million of property and equipment,
$0.4 million of other assets and $0.2 million in cash, offset by
$3.0 million of assumed liabilities.  The excess of the purchase
price over the fair value of net assets acquired was $2.4
million and was allocated to goodwill. The total purchase price
of $4.3 million is comprised of $2.6, paid in cash and the
balance in seller financing.

     During the three months ended March 31, 2000, we paid
approximately $2.1 million related to contingent consideration
from earlier acquisitions which was recorded as additional
goodwill.

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

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

(1) For the three months ended March 31, 2001 and 2000, consists of our Brazilian operations.  As
of March 31, 2001 and 2000, total assets for Brazil consisted of $43.0 million and $47.9 million,
respectively and the remainder relates to our interest in international assets not related to our
core business.

(2) Consists of non-core construction and corporate operations, which includes interest expense net
of interest income of $2.3 million and $4.3 million for 2001 and 2000, respectively.




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

Note 4 - Commitments and Contingencies

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

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

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

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

     Our operations in Brazil are subject to the risks of
political, economic or social instability, including the
possibility of expropriation, confiscatory taxation, hyper-
inflation or other adverse regulatory or legislative
developments, or limitations on the repatriation of investment
income, capital and other assets. We cannot predict whether any
of such factors will occur in the future or the extent to which
such factors would have a material adverse effect on our
Brazilian operations.

Note 5 - Receivables

     From time to time, in exchange for one or more of long-term
exclusive infrastructure services agreements, interest,
financing and other fees, and warrants or other equity interests
in the client, we may grant to our clients payment terms
typically for six to eighteen months.  At March 31, 2001, we had
$38.9 million under these arrangements.

                            $337,212  $272,694  $ 64,518  23.7%
                            ========  ========  =========

     Our revenue was $337.2 million for the three months ended
March 31, 2001, compared to $272.7 million for the same period
in 2000, representing an increase of $64.5 million or 23.7%. We
experienced growth in our datacom network services segment
primarily due to the increased demand for bandwidth by end-users
which has spurred network construction and upgrades by our
clients. Revenue generated by our energy network services
segment decreased slightly as we continue to position the unit
for improved profitability in the future.

     Our costs of revenue were $265.4 million or 78.7% of
revenue for the three months ended March 31, 2001, compared to
$208.9 million or 76.6% of revenue for the same period in 2000.
In 2001, margins were impacted by the rapid deceleration of
anticipated demand for our switching and central office services
in our network services division, adverse weather and reduced
margins in our international operations.

     Depreciation was $13.3 million or 3.9% of revenue for the
three months ended March 31, 2001, compared to $13.5 million or
4.9% of revenue for the same period in 2000.  The decline in
depreciation as a percentage of revenue in 2001 was due to our
ability to more efficiently utilize our equipment.

     Amortization was $2.9 million or 0.9% of revenue for the
three months ended March 31, 2001, compared to $3.5 million or
1.3% of revenue for the same period in 2000.  Decrease of $0.6
million is due primarily to an acceleration of amortization
related to our international operations during 2000.
Amortization of goodwill net of tax was $0.04 million in 2001
and $0.05 million in 2000 which includes the acceleration in
2000.


     General and administrative expenses were $47.9 million or
14.2% of revenue for the three months ended March 31, 2001,
compared to $23.1 million or 8.5% of revenue for the same period
in 2000.  Included in general and administrative expense in 2001
is a provision of $22.0 million related to a reserve for a
portion of receivables due from clients who have filed for
Chapter 11 bankruptcy reorganization recently or who have
experienced difficulties in raising funding due to current
economic conditions. Excluding the reserve, general and
administrative expenses were 7.7% of revenue. The decline in
general and administrative expenses as a percentage of revenue
in 2001, excluding the provision for bad debt, was due primarily
to our ability to continue to support higher revenue with a
comparatively lower administrative base.

     Interest expense, net of interest income, was $2.3 million
or 0.7% of revenue for the three months ended March 31, 2001,
compared to $4.3 million or 1.6% of revenue for the same period
in 2000. The decrease in net interest expense of $2.0 million
was due primarily to lower average outstanding debt under our
revolving credit facility and greater interest income in 2001
when compared to 2000.

     For the three months ended March 31, 2001, our effective
tax rate was approximately 40.3% for North American operations
and 33% for Brazilian operations, compared to 42.0% and 33.0% in
2000 for North American and Brazilian operations, respectively.

Financial Condition, Liquidity and Capital Resources

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

     Net cash used in operating activities was $24.0 million for
the three months ended March 31, 2001, compared to $20.6 million
for the same period in 2000. Net cash used in operating
activities in 2001 and 2000 was due principally to increased
working capital needs as a result of growth in revenue and
changes in client mix. From time to time, in exchange for one or
more of long-term exclusive infrastructure services agreements,
interest, financing and other fees, and warrants or other equity
interests in the client, we may grant to our clients payment
terms typically for six to eighteen months. At March 31, 2001,
we had $38.9 million under these arrangements.



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

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

     During 2001, we invested $10.6 million primarily in our
fleet to support revenue growth and $2.0 million in technology
investments. We also invested $4.8 million in acquisitions and
investments.  We have reflected in other current liabilities
additional consideration by reason of earnouts with respect to
prior years' acquisitions of an aggregate of approximately $35.0
million that we expect will be paid predominately during 2001.

Seasonality

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

Impact of Inflation

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

forth in this Agreement, the parties agree as follows:

1.  The Company hereby employs the Executive and the Executive
hereby accepts such employment as Senior Vice President and Chief
Operating Officer of the Company and its subsidiaries, upon the
terms and conditions set forth in this Agreement. The Executive
will report to the Board of Directors of the Company or its
designee and to the Chief Executive Officer of the Company. The
Executive will have such responsibilities and perform such duties
as the Board of Directors of the Company or its designee assigns
to the Executive, commensurate with his position as Senior Vice
President and Chief Operating Officer of the Company.

2.  The Executive's employment will be for a term commencing on
January 1, 2001 and ending on the close of business December 31,
2002 (the "Employment Term").  The Employment Term may be extended
by mutual agreement of the parties.

3.  During the Employment Term, the Executive will devote the
Executive's full working time, attention and energies to the
business of the Company and its subsidiaries, except that the
Company acknowledges that the Executive may continue to devote a
reasonable amount of his time to serving on the board of directors
of charitable or non-profit organizations so long as such
activities do not unreasonably interfere with the discharge of his
duties for the Company. The Executive will be employed by the
Company at the Company's office in Fort Myers, Florida, and will
travel to such other locations as may be necessary to discharge
his duties. The Company will maintain an office at the Company's
facility in Fort Myers, Florida, and will provide secretarial and
other support personnel for the Executive, in each case
commensurate with the Executive's status as Senior Vice President
and Chief Operating Officer of the Company. The Company will not
request or require the Executive to be employed at another
location without the Executive's consent.

4.  The Company will pay to the Executive as compensation for
services rendered during the Employment Term a salary of not less
than $325,000.00 per annum for the year ending December 31, 2001;
the salary for the year ending December 31, 2002 will be
determined by the Compensation Committee of the Board of Directors
of the Company but will not be less than the prior year's salary
(the amount described in this Section 4 for each year, the
"Salary").  The Salary will be paid in accordance with the
Company's normal payroll practices and will be subject to
withholding of taxes and other deductions required by law.

5.  The Company and the Executive will agree on a bonus plan for
calendar year 2001 and 2002 as soon as possible after the close of
the preceding calendar year, which bonus plan will be at least as
favorable to the Executive as the 2000 Senior Management Incentive
Compensation Plan. The Board of Directors of the Company may, on
its own initiative and in its sole discretion, award cash or other
bonuses to the Executive, whether or not any of the performance
thresholds in the bonus plan are achieved by the Company or the
Executive.

6.  The Company may terminate the employment of the Executive
under this Agreement at any time with or without "Cause" (as
defined below), subject to the other terms and conditions of this
Agreement, by giving the Executive five (5) business days' prior
written notice of termination. In addition to any other
compensation or benefits payable to the Executive under this
Agreement, the Executive upon a termination of employment will
receive all amounts due to the Executive under the Company's
401(k) retirement plan, deferred compensation plan, split dollar
insurance policy or any other benefit plan of the Company in which
the Executive participates. The Executive also will be entitled to
elect continuation of health benefits under COBRA.

7.  In the event of (a) a "Change of Control" (as defined below)
or (b) a termination of employment (including as a result of death
or "Disability," as defined below) prior to the expiration of the
Employment Term other than for Cause (each of (a) and (b) a
"Triggering Event"), the Company will pay in cash to the
Executive, immediately upon the effective date of the Triggering
Event and in lieu of all other compensation under this Agreement,
(i) any unpaid portion of the Salary in respect of the remainder
of the Employment Term, (ii) a bonus equal to the greater of (1)
the aggregate of all bonuses under any bonus plans agreed to by
the Company and Executive for 2001 and 2002 that would have been
earned if the Executive was employed for the full performance
period under the bonus plans, to the extent such bonuses have not
already been earned and paid or (2) (x) $2,000,000.00 if the
Triggering Event occurs on or after January 1, 2001 and prior to
January 1, 2002, and (y) $1,000,000.00 if the Triggering Event
occurs on or after January 1, 2002. In addition, upon the
occurrence of a Triggering Event, all of the Executive's stock
options or restricted stock awards under the Company's 1994 Stock
Incentive Plan, 1999 Non-Qualified Employee Stock Option Plan or
any other option or benefit plan will immediately upon the
effective date of the Triggering Event (A) in the case of options,
become fully vested and immediately exercisable and may be
exercised by Executive for the full remaining term of the options,
and (B) in the case of restricted stock, all restrictions on the
stock will lapse and the stock may be freely sold without further
restriction except as required by applicable law.

8.  If any payment or benefits under this Agreement become subject
to the excise tax imposed by Section 4999 of the Internal Revenue
Code of 1986, as amended (the "Code"), or any substitute provision
of the Code, or any interest or penalties are incurred by
Executive with respect to such excise tax (collectively, the
"Excise Tax"), then the Company will pay Executive an additional
amount or amounts (the "Gross-up Payment") such that the net
amount or amounts retained by Executive, after deduction of any
Excise Tax on any of the payments or benefits under this Agreement
and any federal, state and local income tax and Excise Tax on the
Gross-up Payment, will equal the amount of such payment or
benefits prior to the imposition of such Excise Tax. For purposes
of determining the amount of a Gross-up Payment, Executive will be
deemed to pay federal income taxes at the highest marginal rate of
federal income taxation in the calendar year in which the Gross-up
Payment is payable and state and local income taxes at the highest
marginal rate of taxation in the state and locality of Executive's
residence on the date the Gross-up Payment is payable, net of the
maximum reduction in federal income taxes that could be obtained
from any available deduction of such state and local taxes.

     a.  The Company will pay each Gross-up Payment on the date on
which Executive becomes entitled to the payment or benefits giving
rise to the Excise Tax. If the amount of the Excise Tax is later
determined to be less than the amount taken into account in
calculating the Gross-up Payment, Executive will repay to the
Company (to the extent actually paid by the Company) the portion
of the Gross-up Payment attributable to the overstated amount of
Excise Tax at the time such reduction is finally determined, plus
interest at the rate set forth in Section 1274(b)(2)(B) of the
Code. If the amount of the Excise Tax is later determined to be
more than the amount taken into account in calculating the Gross-
up Payment, the Company will pay Executive an additional Gross-up
Payment in respect of the additional amount of Excise Tax at the
time the amount of the additional tax is finally determined.

9.  In the event of a termination of employment for Cause, the
Company will pay in cash to the Executive any accrued and unpaid
Salary to the date of termination. The Executive will not be
entitled to any bonus under any bonus plan or under paragraph 7 of
this Agreement, or to any other compensation from the Company, and
all unvested stock options or restricted stock as to which the
restriction has not lapsed owned by the Executive will terminate
upon the effective date of termination of employment.

     Notwithstanding any other provisions of this Agreement, in no
event will the Company cause a termination of employment for Cause
without at least forty-five (45) days' notice to the Executive and
approval of such termination for Cause by the entire Board of
Directors of the Company.

10.  The Company will pay for or reimburse the Executive, in
accordance with its practice for executive officers of the
Company, all reasonable and necessary expenses and other
disbursements incurred by the Executive for or on behalf of the
Company in the performance of his duties hereunder. The Executive
will provide such appropriate documentation of expenses and
disbursements as may from time to time be reasonably requested by
the Company.

11.  The Company will (a) indemnify and hold the Executive
harmless for any claims, demands, damages, liabilities, losses,
costs and expenses (including attorneys' and paralegal fees and
court costs) incurred or suffered by the Executive in connection
with the Executive's performance of his duties under this
Agreement or otherwise on behalf of the Company or its affiliates
to the fullest extent (including advancement of expenses)
permitted by Florida corporate law for the indemnification of
officers and directors of a Florida corporation, and (b) will
include the Executive as a covered employee under the Company's
directors' and officers' liability insurance policy and employment
practices liability insurance policy.

12.  The Executive (and his family) will be entitled to
participate in all of the Company's group health, dental and
disability plans, and other benefit plans for executives of the
Company. The Executive will receive any and all other benefits
accorded by the Company to executive officers of the Company.

13.  The parties acknowledge that the provisions of this Agreement
are highly confidential and that disclosure of this Agreement or
its terms would be extremely prejudicial to the other party.
Accordingly, neither party will disclose the terms of this
Agreement to any other person or entity other than third party
advisors with a need to know (such as legal or tax advisors) and
other than when required by law, without the prior written consent
of the other party.

14.  The Executive acknowledges that as a result of his employment
with the Company, the Executive will gain knowledge of, and will
have access to, proprietary and confidential information and trade
secrets of the Company and its affiliates. Therefore, Executive
agrees that he will not, in any fashion, form or manner, directly
or indirectly (i) use, disclose, communicate or provide or permit
access to any person or entity, or (ii) remove from the premises
of the Company or any of its affiliates any notes or records
(including copies or facsimiles, whether made by electronic,
electrical, magnetic, optical, laser acoustic or other means),
relating to any confidential, proprietary or secret information of
the Company or any of its affiliates (collectively, "Confidential
Information") (including without limitation (1) the identity of
customers, suppliers, subcontractors and others with whom they do
business; (2) their marketing methods, strategies and related
information; (3) contract terms, pricing, margin or cost
information or other information regarding the relationship
between them and the persons and entities with which they have
contracted; (4) their services, products, software, technology,
developments, improvements and methods of operation; (5) their
results of operations, financial condition, projected financial
performance, sales and profit performance and financial
requirements; (6) the identity of and compensation paid to their
employees and consultants; (7) any business plans, models or
strategies and the information contained therein; (8) their
sources, leads or methods of obtaining new business; and (9) all
other confidential information of, about or concerning the
business of the Company and its affiliates), except for (x)
information that is or becomes available to the public generally
other than as a result of an unauthorized disclosure by the
Executive, including as an example publicly-available information
filed by the Company with the Securities and Exchange Commission
or other governmental or regulatory authorities, (y) information
that is generally known in the business of the Company or its
affiliates or that constitutes standard industry practices,
customs and methods, or (z) information known to the Executive
prior to joining the Company or its predecessors or gained during
his employment with the Company from sources outside of the
Company or its employees, officers, directors, consultants,
advisors or other representatives. The Executive will be entitled
to use Confidential Information in the discharge of his duties to
the Company.

15.  In consideration of the compensation and benefits paid to
Executive under this Agreement, Executive agrees that during the
Employment Term and, in the case of a termination of this
Agreement for Cause, for two (2) years after the termination (the
"Non-Competition Period"), Executive will not within the United
States of America or the Commonwealth of Canada:

     a.  directly or indirectly own, manage, operate, control, be
employed by, consult with or participate in the ownership,
management, operation or control of, or be connected in any manner
with, any business of the type and character engaged in and
competitive with the business of the Company or any of its
affiliates, as it exists now or in the future.  For these
purposes, ownership of securities of 1% or less of any class of
securities of a public company will not be considered to be
competition with the Company;

     b.  solicit, persuade or attempt to solicit or persuade any
existing customer or any client or potential customer or client to
which the Company or any of its affiliates has made a presentation
or with which any of them has been having discussions to cease

or not to hire the Company or any of its affiliates or to commence
doing business with or increase the amount of business done with
or hire another person or entity;

     c.  solicit, persuade or attempt to solicit or persuade any
individual who is an employee of  the Company or any of its
affiliates to leave their employ or to become employed by any
other person or entity.

It is the desire and intent of the parties to this Agreement that
the provisions of Sections 14 and 15 will be enforced to the
fullest extent permissible under the laws and public policies
applied in each jurisdiction in which enforcement is sought.  If
any particular provisions or portion of Sections 14 or 15 is
adjudicated invalid or unenforceable, this section will be deemed
amended to delete any provision or portion adjudicated to be
invalid or unenforceable, the amendment to apply only with respect
to the operation of that section in the particular jurisdiction in
which the adjudication is made.  The parties recognize that the
performance by Executive of his obligations under Sections 14 and
15 are special, unique and extraordinary in character, and that if
Executive breaches or threatens to breach the terms and conditions
of this Agreement, the Company may suffer irreparable injury for
which no adequate remedy at law may exist.  Accordingly, in the
event of such breach or threatened breach, the Company will be
entitled, if it so elects, to institute and prosecute proceedings
in any court of competent jurisdiction, either in law or in
equity, to obtain damages for any breach of this Agreement, to
enforce the specific performance of this Agreement by Executive,
or to enjoin Executive from breaching or attempting to breach this
Agreement.

16.  THE COMPANY AND EXECUTIVE KNOWINGLY, VOLUNTARILY,
IRREVOCABLY, UNCONDITIONALLY AND INTENTIONALLY WAIVE THE RIGHT TO
A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON THIS
AGREEMENT, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS

amount or amounts retained by Executive, after deduction of any
Excise Tax on any of the payments or benefits under this Agreement
and any federal, state and local income tax and Excise Tax on the

Payment is payable and state and local income taxes at the highest
marginal rate of taxation in the state and locality of Executive's

that the provisions of Sections 14 and 15 will be enforced to the
fullest extent permissible under the laws and public policies
applied in each jurisdiction in which enforcement is sought.  If
any particular provisions or portion of Sections 14 or 15 is
adjudicated invalid or unenforceable, this section will be deemed
amended to delete any provision or portion adjudicated to be
invalid or unenforceable, the amendment to apply only with respect
to the operation of that section in the particular jurisdiction in
which the adjudication is made.  The parties recognize that the
performance by Executive of his obligations under Sections 14 and
15 are special, unique and extraordinary in character, and that if
Executive breaches or threatens to breach the terms and conditions
of this Agreement, the Company may suffer irreparable injury for
which no adequate remedy at law may exist.  Accordingly, in the
event of such breach or threatened breach, the Company will be
entitled, if it so elects, to institute and prosecute proceedings
in any court of competent jurisdiction, either in law or in
equity, to obtain damages for any breach of this Agreement, to
enforce the specific performance of this Agreement by Executive,
or to enjoin Executive from breaching or attempting to breach this
Agreement.

                              Carmen Sabater



                     EMPLOYMENT AGREEMENT

     AGREEMENT effective as of January 1, 2001 between MASTEC,
INC. (the "Company") and JOSE SARIEGO (the "Executive").

     In consideration of the mutual covenants and obligations set
forth in this Agreement, the parties agree as follows:
1.  The Company hereby employs the Executive and the Executive
hereby accepts such employment as Senior Vice President and
General Counsel of the Company and its subsidiaries, upon the
terms and conditions set forth in this Agreement. The Executive
will report to the Board of Directors of the Company or its
designee and to the Chief Executive Officer of the Company. The
Executive will have such responsibilities and perform such duties
as the Board of Directors of the Company or its designee assigns
to the Executive, commensurate with his position as Senior Vice
President and General Counsel of the Company.

2.  The Executive's employment will be for a term commencing on
January 1, 2001 and ending on the close of business December 31,
2002 (the "Employment Term").  The Employment Term may be extended
by mutual agreement of the parties.

3.  During the Employment Term, the Executive will devote the
Executive's full working time, attention and energies to the
business of the Company and its subsidiaries, except that the
Company acknowledges that the Executive may continue to devote a
reasonable amount of his time to serving on the board of directors
of charitable or non-profit organizations so long as such
activities do not unreasonably interfere with the discharge of his
duties for the Company. The Executive will be employed by the
Company at the Company's headquarters in Miami, Florida, and will
travel to such other locations as may be necessary to discharge
his duties. The Company will maintain an office at the Company's
headquarters facility in Miami, Florida, and will provide
secretarial and other support personnel for the Executive, in each
case commensurate with the Executive's status as Senior Vice
President and General Counsel of the Company. The Company will not
request or require the Executive to be employed at another
location without the Executive's consent.

4.  The Company will pay to the Executive as compensation for
services rendered during the Employment Term a salary of not less
than $240,000.00 per annum for the year ending December 31, 2001;
the salary for the year ending December 31, 2002 will be
determined by the Compensation Committee of the Board of Directors
of the Company but will not be less than the prior year's salary
(the amount described in this Section 4 for each year, the
"Salary").  The Salary will be paid in accordance with the
Company's normal payroll practices and will be subject to
withholding of taxes and other deductions required by law.

5.  The Company and the Executive will agree on a bonus plan for
calendar year 2001 and 2002 as soon as possible after the close of
the preceding calendar year, which bonus plan will be at least as
favorable to the Executive as the 2000 Senior Management Incentive
Compensation Plan. The Board of Directors of the Company may, on
its own initiative and in its sole discretion, award cash or other
bonuses to the Executive, whether or not any of the performance
thresholds in the bonus plan are achieved by the Company or the
Executive.

6.  The Company may terminate the employment of the Executive
under this Agreement at any time with or without "Cause" (as
defined below), subject to the other terms and conditions of her
Agreement, by giving the Executive five (5) business days' prior
written notice of termination. In addition to any other
compensation or benefits payable to the Executive under this
Agreement, the Executive upon a termination of employment will
receive all amounts due to the Executive under the Company's
401(k) retirement plan, deferred compensation plan, split dollar
insurance policy or any other benefit plan of the Company in which
the Executive participates. The Executive also will be entitled to
elect continuation of health benefits under COBRA.

7.  In the event of (a) a "Change of Control" (as defined below)
or (b) a termination of employment (including as a result of death
or "Disability," as defined below) prior to the expiration of the
Employment Term other than for Cause (each of (a) and (b) a
"Triggering Event"), the Company will pay in cash to the
Executive, immediately upon the effective date of the Triggering
Event and in lieu of all other compensation under this Agreement,
(i) any unpaid portion of the Salary in respect of the remainder
of the Employment Term, (ii) a bonus equal to the greater of (1)
the aggregate of all bonuses under any bonus plans agreed to by
the Company and Executive for 2001 and 2002 that would have been
earned if the Executive was employed for the full performance
period under the bonus plans, to the extent such bonuses have not
already been earned and paid or (B) $400,000.00. In addition, upon
the occurrence of a Triggering Event, all of the Executive's stock
options or restricted stock awards under the Company's 1994 Stock
Incentive Plan, 1999 Non-Qualified Employee Stock Option Plan or
any other option or benefit plan will immediately upon the
effective date of the Triggering Event (A) in the case of options,
become fully vested and immediately exercisable and may be
exercised by Executive for the full remaining term of the options,
and (B) in the case of restricted stock, all restrictions on the
stock will lapse and the stock may be freely sold without further
restriction except as required by applicable law.

8.  If any payment or benefits under this Agreement become subject
to the excise tax imposed by Section 4999 of the Internal Revenue
Code of 1986, as amended (the "Code"), or any substitute provision
of the Code, or any interest or penalties are incurred by
Executive with respect to such excise tax (collectively, the
"Excise Tax"), then the Company will pay Executive an additional
amount or amounts (the "Gross-up Payment") such that the net
amount or amounts retained by Executive, after deduction of any
Excise Tax on any of the payments or benefits under this Agreement
and any federal, state and local income tax and Excise Tax on the
Gross-up Payment, will equal the amount of such payment or
benefits prior to the imposition of such Excise Tax. For purposes
of determining the amount of a Gross-up Payment, Executive will be
deemed to pay federal income taxes at the highest marginal rate of
federal income taxation in the calendar year in which the Gross-up
Payment is payable and state and local income taxes at the highest
marginal rate of taxation in the state and locality of Executive's
residence on the date the Gross-up Payment is payable, net of the
maximum reduction in federal income taxes that could be obtained
from any available deduction of such state and local taxes.

     a.  The Company will pay each Gross-up Payment on the date on
which Executive becomes entitled to the payment or benefits giving
rise to the Excise Tax. If the amount of the Excise Tax is later
determined to be less than the amount taken into account in
calculating the Gross-up Payment, Executive will repay to the
Company (to the extent actually paid by the Company) the portion
of the Gross-up Payment attributable to the overstated amount of
Excise Tax at the time such reduction is finally determined, plus
interest at the rate set forth in Section 1274(b)(2)(B) of the
Code. If the amount of the Excise Tax is later determined to be
more than the amount taken into account in calculating the Gross-
up Payment, the Company will pay Executive an additional Gross-up
Payment in respect of the additional amount of Excise Tax at the
time the amount of the additional tax is finally determined.

9.  In the event of a termination of employment for Cause, the
Company will pay in cash to the Executive any accrued and unpaid
Salary to the date of termination. The Executive will not be
entitled to any bonus under any bonus plan or under paragraph 7 of
this Agreement, or to any other compensation from the Company, and
all unvested stock options or restricted stock as to which the
restriction has not lapsed owned by the Executive will terminate
upon the effective date of termination of employment.
Notwithstanding any other provisions of this Agreement, in no
event will the Company cause a termination of employment for Cause
without at least forty-five (45) days' notice to the Executive and
approval of such termination for Cause by the entire Board of
Directors of the Company.

10.  The Company will pay for or reimburse the Executive, in
accordance with its practice for executive officers of the
Company, all reasonable and necessary expenses and other
disbursements incurred by the Executive for or on behalf of the
Company in the performance of his duties hereunder. The Executive
will provide such appropriate documentation of expenses and
disbursements as may from time to time be reasonably requested by
the Company.

11.  The Company will (a) indemnify and hold the Executive
harmless for any claims, demands, damages, liabilities, losses,
costs and expenses (including attorneys' and paralegal fees and
court costs) incurred or suffered by the Executive in connection
with the Executive's performance of his duties under this
Agreement or otherwise on behalf of the Company or its affiliates
to the fullest extent (including advancement of expenses)
permitted by Florida corporate law for the indemnification of
officers and directors of a Florida corporation, and (b) will
include the Executive as a covered employee under the Company's
directors' and officers' liability insurance policy and employment
practices liability insurance policy.

12.  The Executive (and his family) will be entitled to
participate in all of the Company's group health, dental and
disability plans, and other benefit plans for executives of the
Company. The Executive will receive any and all other benefits
accorded by the Company to executive officers of the Company.

13.  The parties acknowledge that the provisions of this Agreement
are highly confidential and that disclosure of this Agreement or
its terms would be extremely prejudicial to the other party.
Accordingly, neither party will disclose the terms of this
Agreement to any other person or entity other than third party
advisors with a need to know (such as legal or tax advisors) and
other than when required by law, without the prior written consent
of the other party.

14.  The Executive acknowledges that as a result of his employment
with the Company, the Executive will gain knowledge of, and will
have access to, proprietary and confidential information and trade
secrets of the Company and its affiliates. Therefore, Executive
agrees that he will not, in any fashion, form or manner, directly
or indirectly (i) use, disclose, communicate or provide or permit
access to any person or entity, or (ii) remove from the premises
of the Company or any of its affiliates any notes or records
(including copies or facsimiles, whether made by electronic,
electrical, magnetic, optical, laser acoustic or other means),
relating to any confidential, proprietary or secret information of
the Company or any of its affiliates (collectively, "Confidential
Information") (including without limitation (1) the identity of
customers, suppliers, subcontractors and others with whom they do
business; (2) their marketing methods, strategies and related
information; (3) contract terms, pricing, margin or cost
information or other information regarding the relationship
between them and the persons and entities with which they have
contracted; (4) their services, products, software, technology,
developments, improvements and methods of operation; (5) their
results of operations, financial condition, projected financial
performance, sales and profit performance and financial
requirements; (6) the identity of and compensation paid to their
employees and consultants; (7) any business plans, models or
strategies and the information contained therein; (8) their
sources, leads or methods of obtaining new business; and (9) all
other confidential information of, about or concerning the
business of the Company and its affiliates), except for (x)
information that is or becomes available to the public generally
other than as a result of an unauthorized disclosure by the
Executive, including as an example publicly-available information
filed by the Company with the Securities and Exchange Commission
or other governmental or regulatory authorities, (y) information
that is generally known in the business of the Company or its
affiliates or that constitutes standard industry practices,
customs and methods, or (z) information known to the Executive
prior to joining the Company or its predecessors or gained during
his employment with the Company from sources outside of the
Company or its employees, officers, directors, consultants,
advisors or other representatives. The Executive will be entitled
to use Confidential Information in the discharge of his duties to
the Company.

15.  In consideration of the compensation and benefits paid to
Executive under this Agreement, Executive agrees that during the
Employment Term and, in the case of a termination of this
Agreement for Cause, for two (2) years after the termination (the
"Non-Competition Period"), Executive will not within the United
States of America or the Commonwealth of Canada:

     a.  directly or indirectly own, manage, operate, control, be
employed by, consult with or participate in the ownership,
management, operation or control of, or be connected in any manner
with, any business of the type and character engaged in and
competitive with the business of the Company or any of its
affiliates, as it exists now or in the future.  For these
purposes, ownership of securities of 1% or less of any class of
securities of a public company will not be considered to be
competition with the Company;

     b.  solicit, persuade or attempt to solicit or persuade any
existing customer or any client or potential customer or client to
which the Company or any of its affiliates has made a presentation
or with which any of them has been having discussions to cease

or not to hire the Company or any of its affiliates or to commence
doing business with or increase the amount of business done with
or hire another person or entity;

     c.  solicit, persuade or attempt to solicit or persuade any
individual who is an employee of  the Company or any of its
affiliates to leave their employ or to become employed by any
other person or entity.

     It is the desire and intent of the parties to this Agreement
that the provisions of Sections 14 and 15 will be enforced to the
fullest extent permissible under the laws and public policies
applied in each jurisdiction in which enforcement is sought.  If
any particular provisions or portion of Sections 14 or 15 is
adjudicated invalid or unenforceable, this section will be deemed
amended to delete any provision or portion adjudicated to be
invalid or unenforceable, the amendment to apply only with respect
to the operation of that section in the particular jurisdiction in
which the adjudication is made.  The parties recognize that the
performance by Executive of his obligations under Sections 14 and
15 are special, unique and extraordinary in character, and that if
Executive breaches or threatens to breach the terms and conditions
of this Agreement, the Company may suffer irreparable injury for
which no adequate remedy at law may exist.  Accordingly, in the
event of such breach or threatened breach, the Company will be
entitled, if it so elects, to institute and prosecute proceedings
in any court of competent jurisdiction, either in law or in
equity, to obtain damages for any breach of this Agreement, to
enforce the specific performance of this Agreement by Executive,
or to enjoin Executive from breaching or attempting to breach this
Agreement.

16.  THE COMPANY AND EXECUTIVE KNOWINGLY, VOLUNTARILY,
IRREVOCABLY, UNCONDITIONALLY AND INTENTIONALLY WAIVE THE RIGHT TO
A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON THIS

securities or other property, provided that the consolidation or
merger is not with a corporation which was a wholly-owned
subsidiary of the Company immediately before the consolidation or

becomes the beneficial owner (within the meaning of Rule 13d-3
under the Exchange Act), directly or indirectly, of 33% or more of

such 33% beneficial owner, is not (i) a wholly-owned subsidiary of
the Company, (ii) an individual, or a spouse or a child of such
individual, that on January 1, 2001, owned greater than 20% of the

(the "Incumbent Board"), cease for any reason to constitute at
least a majority thereof, provided that any person becoming a
director subsequent to January 1, 2001, whose election, or
nomination for election by the Company'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 the Company in which such
person is named as a nominee for director, without objection to
such nomination) will be, for purposes of this clause, considered
as though such Person were a member of the Incumbent Board.

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

     EXECUTED as of the date first above written.
