SECOND AMENDMENT TO AMENDED AND RESTATED
LOAN AND SECURITY AGREEMENT

          THIS SECOND AMENDMENT TO AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT (this “Amendment”) is made and entered into this 7^th day of November, 2006, by and between MASTEC, INC., a Florida corporation (“MasTec”), the Subsidiaries of MasTec identified on the signature pages hereto (together with MasTec, hereinafter collectively referred to as the “Borrowers”), the financial institutions party from time to time to the Loan Agreement (as hereinafter defined) (the “Lenders”) and BANK OF AMERICA, N.A., a national bank in its capacity as collateral and administrative agent for the Lenders (together with its successors in such capacity, “Agent”).

Recitals:

          Agent, Lenders and Borrowers are parties to a certain Amended and Restated Loan and Security Agreement dated May 10, 2005 (as amended, restated, modified or supplemented, and in effect on the date hereof, the “Loan Agreement”), pursuant to which Agent and Lenders have made certain revolving credit loans and letter of credit accommodations to or for the benefit of Borrowers.

          MasTec provided to ACE American Insurance Company (“ACE”) certain cash collateral as security for MasTec’s obligations to ACE under a certain insurance policy issued by ACE for the benefit of MasTec and the other Borrowers to enable MasTec and Borrowers’ to comply with certain obligations under worker’s compensation laws and similar legislation. Borrowers now desire to replace the cash collateral provided to secure MasTec’s obligations to ACE with a Letter of Credit in the stated amount of $18,000,000 (the amount of the cash collateral currently pledged to ACE) issued pursuant to the Loan Agreement.

          Borrowers have requested that Agent and Lenders agree that the Letter of Credit to be issued to ACE will not result in a reduction in Borrowers’ Availability under the Loan Agreement so long as sufficient cash or other collateral is granted to Agent, for the benefit of itself and Lenders, for such Letter of Credit.

          In furtherance of the foregoing, Borrowers have requested that Agent and Lenders amend the Loan Agreement, and Agent and Lenders are willing to do so, on the terms and subject to the conditions set forth in this Amendment.

          NOW, THEREFORE, for TEN DOLLARS ($10.00) in hand paid and other good and valuable consideration, the receipt and sufficiency of which are hereby severally acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

          1) Definitions. All capitalized terms used in this Amendment, unless otherwise defined herein, shall have the meaning ascribed to such terms in the Loan Agreement.

          2) Amendments to Loan Agreement. The Loan Agreement is hereby amended as follows:

               a. By deleting the definition of “Borrowing Base” in its entirety from Section 1.1 of the Loan Agreement and by inserting the following in lieu thereof:

     Borrowing Base — on any date of determination thereof, an amount equal to the lesser of: (a) the aggregate amount of the Revolver Commitments on such date minus the Availability Reserve on such date, or (b) an amount equal to (i) the sum of the Accounts Formula Amount on such date plus the Eligible Unbilled Accounts Formula Amount on such date plus the Fixed Assets Formula Amount on such date plus the Eligible Cash Collateral Amount on such date minus (ii) the Availability Reserve on such date.

     Eligible Cash Collateral Amount — on any date of determination, an amount equal to the lesser of (i) $18,000,000, and (ii) 100% of the amount of Eligible Cash Collateral on such date; provided, that, it is the intent of the parties that (i) the amount of eligible Cash Collateral maintained in the Ace LC Collateral Account shall be equal to the undrawn amount of the Ace LC on such date, (ii) Borrowers shall not be required on any date to maintain Eligible Cash Collateral in an amount greater than the undrawn amount of the Ace LC on such date, and (iii) to extent that on any date the Eligible Cash Collateral in the Ace LC Collateral Account exceeds the undrawn amount of the Ace LC on such date, BofA or its Affiliate at which the Ace LC Collateral Account is maintained shall, at the request of Borrowers, pay the amount of Eligible Cash Collateral in excess of undrawn amount of the Ace LC to Borrowers.
