THIS AGREEMENT, effective as of this 28^th day of October, 2009, by and between MASTEC, INC., a Florida corporation, with principal offices and place of business in the State of Florida (the “Corporation”), and Jorge Mas, an individual residing in the State of Florida (the “Employee”),

WITNESSETH THAT:

WHEREAS, the Employee is employed by the Corporation; and

WHEREAS, the Corporation recognizes the value of the services performed by the Employee and wishes to encourage his continued employment; and

WHEREAS, the Employee wishes to be assured that he will be entitled to a certain benefits if the Consolidated Split-Dollar Agreement (as defined below) is terminated; and

WHEREAS, the parties hereto intend that this Agreement be considered an unfunded arrangement, maintained primarily to provide deferred compensation benefits for the Employee, a member of a select group of management or highly compensated employees of the Corporation, for purposes of the Employee Retirement Security Act of 1974, as amended;

WHEREAS, the Corporation and the Employee previously entered into a Deferred Bonus Agreement on November 1, 2002 which was subsequently amended on January 6, 2006, effective as of January 1, 2005, (the “Prior Agreement”) and the parties intended that the Prior Agreement provide for payment of such deferred bonus upon termination, due to a change of control in the Corporation, of three split-dollar agreements entered into by the Corporation and the Employee as of December 27, 1995, December 1, 2002, and May 8, 2003 (the “Prior Split-Dollar Agreements”);

WHEREAS, the Prior Split-Dollar Agreements, were amended and restated and consolidated, in their entirety, into one agreement, effective October 28, 2009 (the “Consolidated Split-Dollar Agreement”);

WHEREAS, the parties hereto wish to amend and restate the Prior Agreement to make it applicable to any policies of life insurance subject to the Consolidated Split-Dollar Agreement and to make certain other modifications to the Prior Agreement.

NOW, THEREFORE, in consideration of the premises and of the mutual promises herein contained, the parties hereto agree as follows:

1. Deferred Bonus.

a. Eligibility for Benefit. As of October 28, 2009, the Corporation and the Employee entered into the Consolidated Split-Dollar Agreement. The Employee shall be entitled to receive the Deferred Bonus provided hereunder from the Corporation in the event that the Consolidated Split-Dollar Agreement is terminated as a result of a Change of Control in the Corporation. For purposes hereof, a “Change in Control” shall occur on the date of a change in control, within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended, due to (i) one person, or more than one person acting as a group, acquiring ownership of stock of the Corporation constituting more than 50% of the total fair market value or total voting power of such stock, or (ii) a majority of the Corporation’s board of directors being replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the Corporation’s board of directors prior to the date of such appointment or election.

b. Amount of Deferred Bonus. The amount of the Deferred Bonus to be provided by the Corporation to the Employee under this Section 1 as a result of the termination of the Consolidated Split-Dollar Agreement shall be the sum of the following amounts, determined with respect to each of the life insurance policies that is the subject to the Consolidated Split-Dollar Agreement (each a “Policy”): the greater of (i) the total amount of the premiums payments made by the Corporation under the terms of the Policy (including any amounts rolled over from any life insurance policies that were subject to the Prior Split-Dollar Agreements), or (ii) the cash value of the Policy immediately prior to the Change in Control (excluding surrender charges or other similar charges or reductions) that are subject to the Consolidated Split-Dollar Agreement.

c. Payment of Deferred Bonus. On or as soon as administratively practicable after the date upon which the Employee becomes entitled to the Deferred Bonus as provided above, but in no event later than 60 days after such date, the Corporation shall pay to the Employee an amount equal to the Deferred Bonus, subject to usual withholding taxes.

d. No Trust Created. Notwithstanding anything in this Section 1, no action taken pursuant to its provisions by either the Corporation or the Employee shall create, or be construed to create, a trust of any kind, or a fiduciary relationship between the Corporation and the Employee, his beneficiary or beneficiaries, or any other person.

e. Deferred Bonus Unfunded. Until the occurrence of any event which entitles the Employee to receive the Deferred Bonus provided under this Section 1, such benefit shall remain an asset of the Corporation which, in the event of the Corporation’s insolvency, will be subject to the claims of general creditors of the Corporation. The parties intend this Deferred Bonus to be considered unfunded for federal income tax purposes, so as not to have the benefit provided hereunder be included in the Employee’s income for such tax purposes prior to actual receipt thereof.

f. Benefit Not Transferable. Neither the Employee, his beneficiary or beneficiaries, nor any other person with a beneficial interest in this Agreements shall have any power or right to transfer, assign, anticipate, hypothecate or otherwise encumber any part or all of Employee’s rights with respect to this Deferred Bonus. No such amounts shall be subject to seizure by any creditor or any such beneficiary, by a proceeding at law or in equity, nor shall such amounts be transferable by operation of law in the event of the bankruptcy, insolvency or death of the Employee, his beneficiary or beneficiaries, or any other person with a beneficial interest in this Agreement. Any such attempt at assignment or transfer shall be void.

2. Named Fiduciary, Determination of Benefits, Claims Procedure and Administration.

a. The Corporation is hereby designated as the named fiduciary under this Agreement. The named fiduciary shall have authority to control and manage the operation and administration of this Agreement, and it shall be responsible for establishing and carrying out a funding policy and method consistent with the objectives of this Agreement.

b. Claim. A Participant, beneficiary or other person who believes that he or she is being denied a benefit to which he or she is entitled (hereinafter referred to as “Claimant”), or his or her duly authorized representative, may file a written request for such benefit with the President of the Corporation (the “First Level Reviewer”), setting forth his or her claim. Such claim must be addressed to the President of the Corporation, at its then principal place of business.

c. Claim Decision. Upon receipt of a claim, the First Level Reviewer shall advise the Claimant that a reply will be forthcoming within a reasonable period of time, but ordinarily not later than ninety days, and shall, in fact, deliver such reply within such period. However, the First Level Reviewer may extend the reply period for an additional ninety days for reasonable cause. If the reply period will be extended, the First Level Reviewer shall advise the Claimant in writing during the initial 90-day period indicating the special circumstances requiring an extension and the date by which the First Level Reviewer expects to render the benefit determination. If the claim is denied in whole or in part, the First Level Reviewer will render a written opinion, using language calculated to be understood by the Claimant, setting forth:

(1) the specific reason or reasons for the denial;

(2) the specific references to pertinent Plan provisions on which the denial is based;

(3) a description of any additional material or information necessary for the Claimant to perfect the claim and an explanation as to why such material or such information is necessary;

(4) appropriate information as to the steps to be taken if the Claimant wishes to submit the claim for review, including a statement of the Claimant’s right to bring a civil action under Section 502(a) of ERISA following an adverse benefit determination on review; and

(5) the time limits for requesting a review of the denial under Subsection C hereof and for the actual review of the denial under Subsection D hereof.

d. Request for Review. Within sixty days after the receipt by the Claimant of the written opinion described above, the Claimant may request in writing that the Secretary of the Corporation (the “Second Level Reviewer”) review the First Level Reviewer’s prior determination. Such request must be addressed to the Secretary of the Corporation, at its then principal place of business. The Claimant or his or her duly authorized representative may submit written comments, documents, records or other information relating to the denied claim, which such information shall be considered in the review under this subsection without regard to whether such information was submitted or considered in the initial benefit determination.

The Claimant or his or her duly authorized representative shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information which (i) was relied upon by the First Level Reviewer in making its initial claims decision, (ii) was submitted, considered or generated in the course of the First Level Reviewer making its initial claims decision, without regard to whether such instrument was actually relied upon by the First Level Reviewer in making its decision or (iii) demonstrates compliance by the First Level Reviewer with its administrative processes and safeguards designed to ensure and to verify that benefit claims determinations are made in accordance with governing Plan documents and that, where appropriate, the Plan provisions have been applied consistently with respect to similarly situated claimants. If the Claimant does not request a review of the First Level Reviewer’s determination within such sixty-day period, he or she shall be barred and estopped from challenging such determination.

e. Review of Decision. Within a reasonable period of time, ordinarily not later than sixty days, after the Second Level Reviewer’s receipt of a request for review, it will review the First Level Reviewer’s prior determination. If special circumstances require that the sixty-day time period be extended, the Second Level Reviewer will so notify the Claimant within the initial 60-day period indicating the special circumstances requiring an extension and the date by which the Second Level Reviewer expects to render its decision on review, which shall be as soon as possible but not later than 120 days after receipt of the request for review. In the event that the Second Level Reviewer extends the determination period on review due to a Claimant’s failure to submit information necessary to decide a claim, the period for making the benefit determination on review shall not take into account the period beginning on the date on which notification of extension is sent to the Claimant and ending on the date on which the Claimant responds to the request for additional information.

The Second Level Reviewer has discretionary authority to determine a Claimant’s eligibility for benefits and to interpret the terms of the Plan. Benefits under the Plan will be paid only if the Second Level Reviewer decides in its discretion that the Claimant is entitled to such benefits. The decision of the Second Level Reviewer shall be final and non-reviewable, unless found to be arbitrary and capricious by a court of competent review. Such decision will be binding upon the Employer and the Claimant.

If the Second Level Reviewer makes an adverse benefit determination on review, the Second Level Reviewer will render a written opinion, using language calculated to be understood by the Claimant, setting forth:

(1) the specific reason or reasons for the denial;

(2) the specific references to pertinent Plan provisions on which the denial is based;

(3) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information which (i) was relied upon by the Second Level Reviewer in making its decision, (ii) was submitted, considered or generated in the course of the Second Level Reviewer making its decision, without regard to whether such instrument was actually relied upon by the Second Level Reviewer in making its decision or (iii) demonstrates compliance by the Second Level Reviewer with its administrative processes and safeguards designed to ensure and to verify that benefit claims determinations are made in accordance with governing Plan documents, and that, where appropriate, the Plan provisions have been applied consistently with respect to similarly situated claimants; and

(4) a statement of the Claimant’s right to bring a civil action under Section 502(a) of ERISA following the adverse benefit determination on such review.
