                               AND GENERAL RELEASE

         This Separation Agreement and General Release (the "Agreement") is

         2. Employees' employment shall terminate on the Effective Date. The
date of Employee's termination shall be referred to as the Separation Date. The
period of time between the Separation Date and December 31, 2004 shall be
referred to as the Term of this Separation Agreement. The Parties agree the
Employee is being terminated "without cause" as such term is defined in that
certain Employment Agreement entered into between MasTec and Employee dated
January 9, 2004 (the "Employment Agreement").

         3. MasTec shall pay Employee the following ("Severance Benefits"):

Separation Date through and including December 31, 2004, which base salary shall
not be subject to mitigation, and (b) all benefits set forth in Section 4(b) of
the Employment Agreement, provided only that with respect to Company benefits,
including medical, disability insurance, life insurance and the Company's
401(k), said benefits shall terminate earlier in the event that Employee
receives like or similar benefits from a different employer between the
Separation Date and December 31, 2004);

                  (b) The Parties acknowledge that in accordance with Section
4(a) of the Employment Agreement, Employee's Base Salary for the period
commencing January 9, 2004, is $300,000.00;

                  (c) The Company acknowledges Employee voluntarily forfeited
$30,000.00 of his compensation during 2003 as part of a Company cost cutting
measure. The Company agrees to pay said amount to Employee within ten (10) days
of execution of this Separation Agreement; and

(d) Subject to the limitations set forth in Section 4(d) of the Employment
Agreement, all previously issued options (i.e., options previously awarded to
Employee in accordance with the terms of the 1994 Stock Incentive Plan and the
1999 Non-Qualified Employee Stock Option Plan as well as the options to purchase
one hundred thousand (100,000) shares of common stock of the Company granted
under the Employment Agreement) will vest in accordance with the incentive stock
option plan and their respective vesting schedules provided. The Options shall
remain exercisable for a period of six (6) months after the last options vest.

         4. During the term of this Separation Agreement, Employee shall

                  Period"), Employee shall provide such consulting services
                  ("Consulting Services") (i) as may be reasonably necessary or
                  appropriate in order to effect an orderly transition

                  of Employee's responsibilities to one or more other employees
                  of MasTec and to ensure that MasTec is aware of all matters
                  that were handled by Employee during his employment by MasTec
                  and (ii) as may be reasonably requested by MasTec in
                  connection with general corporate matters.

         b.       During the Consulting Period, Employee shall not have any
                  formal schedule of duties or assignments, but (i) for the
                  first ninety (90) days after the Separation Date (the "Initial
                  Consulting Period"), Employee shall make himself available for
                  up to 20 hours per week to perform the Consulting Services and

                  reasonable advance notice from MasTec of the time requested
                  for such Consulting Services, which time shall not
                  unreasonably interfere with Employee's other activities.
                  Employee may perform Consulting Services by telephone and may
                  be required to travel in connection with his performance of
                  Consulting Services.

         c.       Employee agrees that Consulting Services provided by him
                  during the Initial Consulting Period shall be provided without
                  charge to MasTec.

         d.       For all other services rendered to Employer during the term of
                  this Separation Agreement (except as limited by Paragraph 8,
                  below), the Employee shall be paid at the rate of $350 per
                  hour (the "Consulting Fee").

         e.       MasTec agrees to reimburse Employee within thirty (30) days
                  for reasonable expenses incurred by him in connection with his
                  rendering of Consulting Services to the extent such expenses
                  are reimbursable under MasTec's policy for business expenses
                  as provided to him from time to time. Employee will provide
                  appropriate documentation of expenses as required under said
                  policy.

         5. Employee agrees that the Severance Benefits constitute sufficient
consideration for this Agreement. Employee acknowledges and agrees that no
consideration other than the Severance Benefits as provided for by this
Agreement has been or will be paid or furnished by Employer. Employee
acknowledges that the Severance Benefits includes compensation for any right
Employee may have or have had to (a) vacation, holiday, sick or personal days or
pay in lieu thereof, and (b) bonus, profit sharing or other incentive
compensation. Employee acknowledges that the Severance Benefits and any
Consulting Fee paid under this Agreement are compensation and will be included
in either a W-2 earnings statement or a 1099 statement, and are subject to
applicable payroll withholding taxes.

         6. Employee agrees, as a condition precedent to receipt of the
Severance Benefits pursuant to this Agreement, that Employee will deliver or
cause to be delivered to Employer not later than the Separation Date, (a) all
keys, ID cards, corporate credit card, radio, electronic beeper or other

from the beginning of time to the date of this Agreement. Employee is not
releasing any right or claims he may have personally to any Director and Officer
Liability protection to which he may be entitled as a result of his employment

         8. MasTec and the MasTec Released parties acquit, release and forever

or any of its subsidiaries or affiliates, by furnishing such information and
appropriate services (including, if required, testimony) any by making himself

be without charge to MasTec.

         10. In exchange for the Severance Benefits, Employee acknowledges and

infrastructure services businesses (the "BUSINESS") are conducted throughout the
United States of America and the Commonwealth of Canada. Until two (2) years
following the Separation Date and within the United States of America and the
Commonwealth of Canada (including their possessions, protectorates and
territories, the "Territory"), Employee will not (whether or not then employed
by the Company for any reason), without the Company's prior written consent:

                  (i) directly or indirectly own, manage, operate, control, be
employed by, act as agent, consultant or advisor for, or participate in the
ownership, management, operation or control of, or be connected in any manner
through the investment of capital, lending of money or property, rendering of
services or otherwise, with, any business of the type and character engaged in
and competitive with the Business. For these purposes, ownership of securities
of one percent (1%) or less of any class of securities of a public company will
not be considered to be competition with the Business;

                  (ii) solicit, persuade or attempt to solicit or persuade or
cause or authorize directly or indirectly to be solicited or persuaded any
existing customer or client, or potential customer or client to which the

done with or not to hire the Companies, or to commence doing Business with or
increase the amount of Business done with or hire another company;

                  (iii) solicit, persuade or attempt to solicit or persuade or
cause or authorize directly or indirectly to be solicited or persuaded the
business of any person or entity that is a customer or client of the Companies,
or was their customer or client within two (2) years prior to cessation of
Employee's employment by any of the Companies or any of their subsidiaries, for
the purpose of competing with the Business; or

                  (iv) solicit, persuade or attempt to solicit or persuade, or
cause or authorize directly or indirectly to be solicited or persuaded for
employment, or employ or cause or authorize directly or indirectly to be
employed, on behalf of Employee or any other person or entity, any individual
who is or was at any time within six (6) months prior to cessation of Employee's
employment by the Companies, an employee of any of the Companies.

         If Employee breaches or violates any of the provisions of this SECTION
9, the running of the Period of Non-Competition (but not of any of Employee's
obligations under this SECTION 9) will be tolled with respect to Employee during
the continuance of any actual breach or violation. In addition to any other
rights or remedies the Company may have under this Agreement or applicable law,
the Company will be entitled to receive from Employee reimbursement for all
attorneys' and paralegal fees and expenses and court costs incurred by the
Companies in enforcing this Agreement and will have the right and remedy to
require Employee to account for and pay over to the Company all compensation,
profits, monies, accruals or other benefits derived or received, directly or
indirectly, by Employee from the action constituting a breach or violation of
this SECTION 9.

         11. Employee permanently, unequivocally and unconditionally waives any
and all rights Employee may have, may have had in the past, or may have in the
future to seek, obtain or resume employment with Employer. Employee further
understands that Employer is under no obligation,

                                      -4-
<PAGE>

presently or at any time in the future, to accept Employee as an employee and
Employer may deny employment to Employee solely based upon this Agreement.

         12. Employee represents and warrants that no person other than
signatories hereto had or has any interest in the matters referred to in this
Agreement, that Employee has the sole right and exclusive authority to execute
this Agreement, and that Employee has not sold, assigned, transferred, conveyed,
or otherwise disposed of any claim or demand relating to any matter covered by
this Agreement.

         13. Employee agrees to indemnify and hold Employer harmless from and
against any and all claims, including Employer's court costs and attorneys' fees
arising from or in connection with any claim, action, or other proceeding made,
brought, or prosecuted, or caused or permitted to be commenced or prosecuted, by
Employee, Employee's successor(s), or assign(s) contrary to the provisions of
the Agreement. It is further agreed that this Agreement will be deemed breached
and a cause of action accrued thereon immediately upon the commencement of any
action contrary to this Agreement, and in any such action this Agreement may be
pleaded by the Employer, or any of them, both as a defense and as a counterclaim
or cross-claim in such action. This paragraph shall not apply to actions brought
pursuant to the Age Discrimination in Employment Act ("ADEA") or the Older
Workers Benefit Protection Act ("OWBPA").

         14. Employee agrees that all matters relating to this Agreement are
strictly confidential and that Employee and/or Employee's attorney will not
disclose or disseminate any information concerning any term or terms hereof to
any third person or persons. Any disclosure or dissemination by Employee will be
regarded as a breach of this Agreement and a cause of action will immediately
accrue for damages, including, but not limited to, the amount paid to Employee
under this Agreement.

Employee acknowledges that as a result of Employee's employment with Employer,
Employee has gained knowledge of, and access to, proprietary and confidential
information and trade secrets of Employer and its subsidiaries and affiliates,
including, without limitation, (1) the identity of customers, suppliers,
subcontractors and others with whom they do business; (2) their marketing
methods and strategies; (3) contract terms, pricing, margin, cost information
and 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, including Employee; (7)
their 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
Employer and its subsidiaries and affiliates (collectively, the "Confidential
Information"). Employee further acknowledges that such information, even though
it may be contributed, developed or acquired by Employee, and whether or not the
foregoing information is actually novel or unique or is actually known by
others, constitutes valuable assets of Employer developed at great expense which
are the exclusive property of Employer or its subsidiaries and affiliates.
Accordingly, Employee will not, at any time, either during or subsequent to the
Term, in any fashion, form or manner, directly or indirectly, (i) use, divulge,
disclose, communicate, provide or permit access to any person or entity, any
Confidential Information of any kind, nature or description, or (ii) remove from
Employer's or its subsidiaries' or affiliates' premises any notes or records
relating thereto, or copies or facsimiles thereof (whether made by electronic,
electrical, magnetic, optical, laser acoustic or other means) except in the case
of both (i) and (ii), (A) as reasonably required in the performance of
Employee's services to Employer under this Agreement, (B) to responsible
officers and employees of Employer who are in a contractual or fiduciary
relationship with Employer and who have a need for such information for purposes
in the best interests of Employer, and (C) for such information which is or
becomes generally available to the public other than as a result of an
unauthorized disclosure by

                                      -5-
<PAGE>

Employee. Employee acknowledges that Employer would not enter into this
Agreement without the assurance that all Confidential Information will be used
for the exclusive benefit of Employer.

         15. The prevailing party will be entitled to any attorneys' fees and
court costs incurred in enforcing this Agreement or in defending any claim
brought in violation hereof, except that this Paragraph shall not apply to
actions brought pursuant to the Age Discrimination in Employment Act ("ADEA") or
the Older Workers Benefit Protection Act ("OWBPA").

         16. Employee fully understands that if any fact with respect to which
this Agreement is executed is found hereafter to be other than or different from
the facts in that connection now believed by Employee to be true, he expressly
accepts and assumes the risk of such possible difference in fact and agrees that
this Agreement will be and remain effective notwithstanding such difference in
fact.

         17. Employee represents and agrees that he has not and will not make or
file or cause to be made or filed any claim, charge, allegation, or complaint,
whether formal, informal, or anonymous, with any governmental agency, department
or division, whether federal, state, or local, relating to Employer in any
manner, including without limitation, Employer's business or employment
practices.

         18. Employee agrees that he will not make any statements about or
relating to MasTec or its affiliates, its officers, directors, shareholders,
agents or independent contractors which are disparaging, critical or likely to
cause embarrassment. In the event Employee becomes employed by a customer of the
Company, Employee agrees not to directly or indirectly negatively impact the
Company's relationship with said customer. MasTec shall not make any statements
about or relating to Employee that are disparaging, critical or likely to cause
embarrassment.

         19. Employer shall provide Employee with a positive reference.

         20. Nothing contained in this Agreement shall preclude the Employer or
the Employee from disclosing information as may be reasonably necessary in any
legal or administrative proceeding, provided however that Employer or Employee
shall be advised of such disclosure and that the parties to this Agreement will
cooperate in obtaining reasonably necessary confidentiality orders.

         21. Employee acknowledges that violation of the Agreement may give rise
to irreparable injury to Employer, inadequately compensable in damages.
Accordingly, Employer may seek and obtain injunctive relief against the breach
or threatened breach of the foregoing, in addition to any other legal remedies
which may be available and which legal remedies are not waived by Employer's
seeking injunctive relief. Employer acknowledges and agrees that the covenants
contained herein are necessary for the protection of Employer's legitimate
business interests.

         22. Pursuant to the provisions of the Older Workers Benefit Protection
Act (OWBPA), which applies to Employee's waiver of rights under the Age
Discrimination in Employment Act, Employee has had a period of at least
twenty-one (21) days within which to consider whether to execute this Agreement.
Also pursuant to the OWBPA, Employee may revoke the Agreement within seven (7)
days of its execution. It is specifically understood that this Agreement will
not become effective or enforceable until the seven-day revocation period has
expired. Consideration for this Agreement will not be paid until the end of the
seven-day revocation period or, if paid before the expiration of the seven-day
revocation period, must be refunded in full to revoke this Agreement.

         23. Employee acknowledges that, pursuant to the OWBPA, Employer advised
Employee, in writing, to consult with an attorney prior to executing this
Agreement

                                      -6-
<PAGE>

         24. This Agreement does not constitute an admission of a violation of
any law, order, regulation, or enactment, or of wrongdoing of any kind by
Employer and is entered into by the parties solely to end any controversy
between them. This Agreement will be governed by and construed and enforced in
accordance with the laws of the State of Florida, without regard to its conflict
of laws rules. The parties agree to submit any claims arising from a breach of
this Agreement, other than those by MasTec claiming a breach of paragraph 9 for
which MasTec shall have the right to seek injunctive relief in state or federal
Court in Miami-Dade County, to binding arbitration with the American Arbitration
Association ("AAA") in Miami, Florida in accordance with the National Rules for
the Resolution of Employment Disputes in effect at the time of filing (the
"Employment Rules").

          This provision is a material inducement for Employer to enter into
this Agreement with Employee.

         25. The waiver by Employer in writing of any provision of this
Agreement will in no manner affect the right to enforce the same, and will not
be construed to be a waiver by Employer of any succeeding breach of such
provision or a waiver of any breach of any other provision.

         26. This Agreement represents the entire understanding and agreement
between the parties hereto with respect to the subject matter hereof and there
are no promises, agreements, conditions, undertakings, warranties, or
representations, whether written or oral, express or implied, between the
parties other than as set forth herein. This Agreement cannot be amended,
supplemented, or modified except by an instrument in writing signed by the
parties against whom enforcement of such amendment, supplement or modification
is sought. Employee will make no claim and waives any right Employee may now
have or may hereafter have based upon any alleged oral alteration, amendment,
modification, or any other alleged change in this Agreement.

         27. This Agreement may be executed in counterparts, each of which will
be considered an original but which will constitute one and the same agreement.

                                      -7-

         effective August 7, 2001 (the "Separation Date") other than Executive's
         existing rights relating to stock options held by him under MasTec's
         stock option plans and MasTec's obligation to fund premiums of an
         additional $150,000 under a deferred compensation life insurance
         program and to maintain the insurance on substantially the same terms
         previously agreed to by MasTec. To this end, effective on the
         Separation Date, Executive resigns as President and Chief Executive
         Officer of MasTec, as a member of the Board of Directors of MasTec, and
         as an executive and member of the board of directors of all of MasTec's
         subsidiaries. Executive shall also resign on the Separation Date from
         the boards of directors (or similar governing bodies) of any entity for
         which Executive serves as a designee of MasTec or its affiliates.

2.       (a)      Subject to the terms and conditions of this Agreement, in
                  connection with Executive's separation from MasTec and in
                  consideration for the covenants and agreements set forth
                  herein, MasTec agrees to pay Executive an aggregate of $10
                  million (the "Severance Pay") payable in cash by wire transfer
                  to the account designated in writing by Executive from time to
                  time as follows:

                           Payment Date                Amount
                           ------------                ------

                           September 3, 2001         $2,000,000
                           January 2, 2002           $2,000,000
                           April 1, 2002             $2,000,000
                           July 1, 2002              $2,000,000
                           October 1, 2002           $2,000,000

                  ; provided, however, that all payments shall accelerate and be
                  due and payable in the event that MasTec fails to make any of
                  the foregoing payments within three business days after
                  written notice from Executive that any such payment has not
                  been timely made.

         (b)      Executive agrees that MasTec may reduce the payment to be made
                  on October 1, 2002 by the amount of all indebtedness owed to
                  MasTec under the Demand Note in the principal amount of
                  $750,000 dated November 1, 2000.

         (c)      Such Severance Pay shall constitute full payment and
                  consideration in connection with the separation and
                  Executive's employment and shall be in lieu of any other
                  payments or consideration arising out of any previous
                  relationship, agreements or arrangements between MasTec or its
                  subsidiaries and affiliates on the one hand, and Executive, on
                  the other.

3.       (a)      From the Separation Date until August 7, 2003 (the "Consulting
                  Period"), Executive shall provide such consulting services
                  (the "Consulting Services") (i) as may be reasonably necessary
                  or appropriate in order to effect an orderly transfer of
                  Executive's responsibilities to one or more other executives
                  of MasTec and to ensure that MasTec is aware of all matters
                  that were handled by Executive during his employment by MasTec
                  and (ii) as may be reasonably requested by MasTec in
                  connection with general corporate matters.

         (b)      During the Consulting Period, Executive shall not have any
                  formal schedule of duties or assignments, but (i) during the
                  period from the Separation Date until November 7, 2001 (the
                  "Initial Consulting Period"), Executive shall make himself
                  available for at least 20 hours per week to

<PAGE>

                  perform the Consulting Services and (ii) during the remainder
                  of the Consulting Period, Executive shall make himself
                  available for at least 20 hours per month to perform the
                  Consulting Services. After the Initial Consulting Period,
                  Executive shall receive reasonable advance notice from MasTec
                  of the time requested for such Consulting Services, which time
                  shall not unreasonably interfere with Executive's other
                  activities. Executive may perform Consulting Services by
                  telephone and may be required to travel in connection with his
                  performance of Consulting Services.

         (c)      MasTec agrees to reimburse Executive for reasonable expenses
                  incurred by him in connection with his rendering of Consulting
                  Services to the extent such expenses are reimbursable under
                  MasTec's policy for business expenses as provided to him from
                  time to time. Executive will provide appropriate documentation
                  of expenses as may from time to time be reasonably requested
                  by MasTec.

         (d)      MasTec agrees that it will provide an office for Executive's
                  use in MasTec's office at 660 Madison Avenue, New York, New
                  York through December 31, 2001 and will continue to (i) employ
                  Krysta Mihalik through December 31, 2001 and (ii) engage
                  Gabriella Grunwald as a consultant through September 30, 2001.
                  Executive will either vacate the New York office on or prior
                  to December 31, 2001 or assume the lease of such space for the
                  remainder of the lease term. In the event Executive assumes
                  the lease, MasTec shall be unconditionally released from any
                  liability thereunder and any letter of credit or security
                  provided by MasTec which is currently held by the landlord or
                  any other third party in connection with such leased office
                  shall be promptly returned to MasTec.

4.       Executive agrees that he will cooperate and assist MasTec in connection
         with any legal, quasi-legal, administrative or other similar
         proceeding, including any external or internal investigation, involving
         MasTec or any of its subsidiaries or affiliates, by furnishing such
         information and appropriate services (including, if required,
         testimony) and by making himself available to MasTec as may be
         reasonably requested by MasTec from time to time.

5.       All stock options to acquire MasTec Common Stock granted to Executive
         under MasTec's 1994 Stock Incentive Plan, as amended, or any other
         option or benefit plan shall, upon the Separation Date, become fully
         vested and immediately exercisable and may be exercised by Executive
         for the full remaining term of the options but in no event later than
         the latest day on which such option may be exercised under the terms of
         the plan under which such option was granted.

6.       Executive acknowledges and agrees that he is not entitled to any
         further payments or benefits other than as provided for by this
         Agreement and he has no additional right to (a) vacation, holiday, sick
         or personal days or pay in lieu thereof, (b) bonus, profit sharing or
         other incentive compensation, or (c) stock options or restricted stock,
         all of which Executive specifically waives; provided, however, that
         Executive is not waiving his rights under the federal law providing for
         continuation of medical coverage commonly known as COBRA. Executive
         agrees and acknowledges that his eligibility (i) to purchase stock
         under the MasTec, Inc. Non-Qualified Employee Stock Purchase Plan, (ii)
         to participate in Employer incentive compensation or other compensation
         plans and (iii) to participate in any other benefit plan of Employer or
         its subsidiaries or affiliates is terminated as of the Separation Date.
         Notwithstanding the foregoing, MasTec agrees to reimburse Executive for
         reasonable business expenses incurred by him prior to the Separation
         Date subject to MasTec's historical policy for the reimbursement of
         business expenses.

7.       Executive agrees that at MasTec's request he will promptly deliver or
         cause to be delivered to MasTec, (a) all keys, ID cards, company
         automobile or other vehicle, corporate credit card, laptop computer or
         other hardware, computer software of any kind, electronic address book,
         portable telephone, radio, electronic beeper or other electronic
         devices, equipment and all other property belonging to MasTec and (b)
         all originals and copies of any drawings, books, manuals, letters,
         notes, notebooks, reports, financial statements, business plans,
         projections, data base, or documents, materials or information in
         Executive's possession or control containing or describing any
         Confidential Information (as defined below) or otherwise relating to
         MasTec or any of its subsidiaries or affiliates; provided, however,
         that Executive will not be required to return the computers (and
         software currently installed therein) in the New York, New York office
         currently being used by him prior to December 31, 2001.

8.       Executive acknowledges that as a result of his employment with MasTec,
         Executive gained knowledge of, and had access to, proprietary and
         confidential information and trade secrets of MasTec and its
         affiliates. Executive agrees that he will not, in any fashion, form or
         manner, directly or indirectly (a) use, disclose,

                                       2
<PAGE>

         communicate or provide or permit access to any person or entity, or (b)
         remove from the premises of MasTec 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
         MasTec 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
         MasTec 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 Executive, including as an example
         publicly-available information filed by MasTec with the Securities and
         Exchange Commission or other governmental or regulatory authorities,
         (y) information that is generally known in the business of MasTec or
         its affiliates or that constitutes standard industry practices, customs
         and methods, or (z) information known to Executive prior to joining
         MasTec or its predecessors or gained during his employment with MasTec
         from sources outside of MasTec or its employees, officers, directors,
         consultants, advisors or other representatives who do not owe a duty of
         confidence to MasTec or any of its affiliates, whether arising under
         contract or otherwise. Executive will be entitled to use Confidential
         Information in the discharge of his Consulting Services.

9.       Executive acknowledges that it is essential to MasTec that Executive
         not utilize his special knowledge of MasTec and its business and his
         relationships with customers, suppliers and other who have business
         dealing with MasTec to compete with MasTec. Accordingly, during the
         Consulting Period, Executive covenants that he 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 ownership,
                  management, operation or control of, or be connect in any
                  manner with, any entity engaged, directly or through one or
                  more subsidiaries, in the business of providing
                  telecommunications or other utility infrastructure services,
                  if such entity derives at least 20% or more of its
                  consolidated revenues from telecommunications or other utility
                  infrastructure services ("Competitor"). For these purposes,
                  ownership of securities of 1% or less of any publicly held
                  class of securities of any Competitor will not be considered
                  to be competition with MasTec;

         (b)      Solicit, persuade or attempt to solicit or persuade any
                  existing customer or any client or potential customer or
                  client to which MasTec or any of its affiliates has made
                  presentation within 3 years prior to the Separation Date or
                  with which any of them has been having discussions, to cease
                  doing business with or decrease the amount of business done
                  with or not to hire MasTec 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 MasTec or any of its
                  affiliates other than Krysta Mihalik to leave their employ or
                  to become employed by any other person or entity.

10.      It is the desire and intent of the parties to this Agreement that the
         provisions of Sections 8 and 9 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 Section 8 or 9 is adjudicated invalid or
         unenforceable, such 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 8 and 9 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, without posting any bond or
         other security, 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, and/or to enjoin Executive from
         breaching or attempting to breach this Agreement.

12.      MasTec and the MasTec Released Parties acquit, release and forever

         kind whatsoever, arising out of, resulting from or in any way connected

         that MasTec or the MasTec Released Parties ever had or may now have

         time to the date of this Agreement, except for Claims arising from (a)

         and the deferred compensation life insurance program.

13.      MasTec agrees that it will (a) indemnify and hold Executive harmless
         for any claims, demands, damages, liabilities, losses, costs and
         expenses (including attorneys' and paralegal fees and court costs)
         incurred or suffered by Executive in connection with Executive's
         service as an executive officer of MasTec 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 corporate and (b) will include Executive as a covered employee
         under MasTec's directors' and officers' liability insurance policy and
         employment practices liability insurance policy until the applicable
         statues of limitations have expired.

14.      Executive represents and warrants that no person other than he had or
         has any interest in the matters referred to in this Agreement, that
         Executive has sole right and exclusive authority to execute this
         Agreement, and that Executive has not sold, assigned, transferred,
         conveyed, or otherwise disposed of any claim or demand relating to any
         matter covered by this Agreement.

15.      Executive agrees that he will not make any statements about or relating
         to MasTec or its affiliates, its officers, directors, shareholders,
         agents or independent contractors which are disparaging, critical or
         likely to cause embarrassment. MasTec shall not make any statements
         about or relating to Executive that are disparaging, critical or likely
         to cause embarrassment.

16.      The Executive acknowledges that MasTec may be required to disclose the
         terms of this Agreement and to issue a public statement regarding
         Executive's resignation if in the opinion of counsel such disclosure is
         required by law. MasTec agrees that it will provide Executive a
         reasonable opportunity to provide comments on any written statements
         regarding the termination of Executive's employment prior to its
         issuance. Executive agrees that he will not issue any public statements
         on Executive's termination of employment (including the circumstances
         giving rise thereto) or the terms hereof, except with the prior written
         consent of MasTec which shall not be unreasonably withheld. Subject to
         paragraph 15, Executive shall be free to discuss his termination with
         potential future employers.

17.      With respect to the provisions of this Agreement other than Sections 8
         and 9 (which are covered by Section 10), Executive acknowledges that
         violation of the Agreement may give rise to irreparable injury to
         MasTec,

                                       4
<PAGE>

         inadequately compensable in damages. Accordingly, MasTec may seek and
         obtain injunctive relief against the breach or threatened breach of the
         foregoing, in addition to any other legal remedies which may be
         available and which legal remedies are not waived by MasTec's seeking
         injunctive relief.

18.      This Agreement will be governed by and construed and enforced in
         accordance with the laws of the State of Florida, without regard to its
         conflict of laws rules. Executive consents to the jurisdiction of any
         state or federal court located within Miami-Dade County, State of
         Florida, and consents that all service of process may be made by
         registered or certified mail directed to Executive at the address of
         Executive in the payroll records of MasTec. Executive waives any
         objection which Executive may have based on lack of jurisdiction or
         improper venue or FORUM NON CONVENIENS to any suit or proceeding
         instituted by MasTec under this Agreement in any state or federal court
         located within Miami-Dade County, Florida and consents to the granting
         of such legal or equitable relief as is deemed appropriate by the
         court. This provision is a material inducement for MasTec to enter into
         this Agreement with Executive.

19.      The waiver by MasTec in writing of any provision of this Agreement will
         not be construed to be a waiver by MasTec or any succeeding breach of
         such provision or a waiver of any breach of any other provision.

20.      This Agreement represents the entire understanding and agreement
         between the parties hereto with respect to the subject matter hereof
         and supercedes and replaces all prior agreements between the parties.
         There are no promises, agreements, conditions, undertakings,
         warranties, or representations, whether written or oral, express or
         implied, between the parties other than as set forth herein. This
         Agreement cannot be amended, supplemented, or modified except by an
         instrument in writing signed by the parties against whom enforcement of
         such amendment, supplement or modification is sought. No party will
         make any claim and each party waives any right such party may now have
         or may hereafter have based upon any alleged oral alteration,
         amendment, modification, or any other alleged change in this Agreement.

21.      If any action or proceeding is brought in any court by any party to
         enforce any provision of this Agreement, the prevailing party shall be
         entitled to recover from the non-prevailing party all of its reasonable
         costs and expenses incurred in connection with such action, including
         reasonable attorneys' fees and disbursements through and including all
         appeals.

22.      This Agreement may be executed in counterparts, each of which will be
         considered an original but which will constitute one and the same
         agreement.

23.      In the event that any provision or portion of this Agreement is
         determined to be invalid or unenforceable for any reason, the remaining
         provisions of this Agreement will be unaffected thereby and will remain
         in full force and effect.

24.      THE PARTIES KNOWINGLY, VOLUNTARILY, IRREVOCABLY, UNCONDITIONALLY AND
         INTENTIALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY
         LITIGATION BASED ON ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
         AGREEMENT OR ANY CLAIMS COVERED BY THIS AGREEMENT, OR ANY COURSE OF
         CONDUCT, COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR
         ACTIONS OF AN PERSON OR PARTY AND RELATED TO THIS AGREEMENT OR ANY
         CLAIMS; THIS IRREVOCABLE WAIVER OF THE RIGHT TO A JURY TRIAL BEING A
         MATERIAL INDUCEMENT FOR EACH PARTY TO ENTER INTO THIS AGREEMENT.
