ITEM 3.02 Unregistered Sales of Equity Securities

On December 24, 2010 (the “Amendment Date”), MasTec Inc. (the “Company”) entered into an amendment (the “Amendment”) to an asset purchase agreement (such agreement as amended through the date hereof, the “Agreement”) pursuant to which it had purchased certain assets and liabilities pertaining to its Nsoro wireless network business from NSORO, LLC, a Georgia limited liability company (the “Seller” and such transaction, the “Acquisition”). The Amendment effectively reduces potential future earn-out payments in exchange for upfront consideration.

Pursuant to the terms of the Amendment, the earn-out payments payable by the Company to the Seller in connection with the Acquisition have been amended as follows: (i) Seller shall receive $40 million in cash and 1,875,000 shares of MasTec, Inc. common stock, par value $0.10 per share (the “MasTec Shares”) in settlement of all earn-out amounts due for the 2010 calendar year, on the Amendment Date; and (ii) Seller shall receive reduced future earn-out payments equal to 27.5% of the earnings before taxes of the domestic Nsoro business (“EBT”) in excess of $40 million for each of the five calendar years commencing on January 1, 2011 and ending on December 31, 2015, and 27.5% of the EBT over $23.3 million for the seven-month period commencing on January 1, 2016 and ending on July 31, 2016 (collectively, the earn-out payments for such future periods, the “Future Earn-Out Payments”). Prior to the Amendment, the terms of the remaining earn-out payments due under the Agreement provided that the Seller would be paid earn-out payments for the six calendar years beginning in 2010 equal to the first $1,750,000 of EBT in excess of $1,750,000 of EBT plus 50% of annual EBT in excess of $3,500,000, and earn-out payments for the seven month period ending July 31, 2016 equal to the first $1,020,000 of EBT in excess of $1,020,000 of EBT plus 50% of annual EBT in excess of $2,040,000 of EBT. The Amendment provides that the MasTec Shares shall be subject to transfer restrictions which shall lapse on the first anniversary of the Amendment Date. Future Earn-Out Payments are payable at MasTec’s option in cash, MasTec common stock (the “Future Earn-Out Shares”) or a combination thereof.
