On February 11, 2011 (the “Effective Date”), MasTec, Inc., a Florida corporation (the “Company” and, including its subsidiaries, “MasTec”) and its wholly owned subsidiary MasTec North America, Inc. entered into an Amended and Restated Purchase Option Agreement (the “Option Agreement”) with Red Ventures LLC (“Red Ventures”) and certain of Red Ventures’ affiliates, which grants Red Ventures a purchase option (the “Option”) to acquire MasTec’s wholly owned subsidiary, DirectStar TV, LLC and its subsidiaries (“DirectStar”). The amendments to the Option Agreement modify the option period and increase the exercise price as described below, as well as certain other terms, and allow Red Ventures to pay up to 35% of the Option purchase price in the form of a secured note with a one-year term. In connection with the entry into the amendments to the Option, MasTec also agreed to increase certain commissions that DirectStar presently pays to Red Ventures for managing the DirectStar business.

Pursuant to the Option Agreement, Red Ventures has an option to purchase DirectStar from MasTec, at any time from March 1, 2012 to November 30, 2012 for an amount equal to the sum of: (i) the shareholders equity of DirectStar as of May 31, 2010, (ii) five percent (5%) of the adjusted net income (generally, the net income (loss) before provision of income taxes) of DirectStar from January 1, 2010 until the last day of the month immediately prior to the date of the sale and (iii) the Factor (as defined in the Option Agreement). The foregoing description of the Option Agreement and terms of the Option is only a summary and is qualified in its entirety by reference to the full text of the Option Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K, and which is incorporated herein by reference.
