Item 1.01 Entry into a Material Definitive Agreement.

On November 28, 2006, Quanta Services, Inc. (“Quanta”) entered into a Joinder Agreement and Amendment to Underwriting, Continuing Indemnity and Security Agreement (the “Joinder Agreement”), among American Home Assurance Company, National Union Fire Insurance Company of Pittsburgh, Pa., and The Insurance Company of the State of Pennsylvania (collectively, the “New Co-Sureties”), Federal Insurance Company, an Indiana corporation (“Federal”), and the other parties designated therein as Indemnitors. Pursuant to the Joinder Agreement, the New Co-Sureties have been added as co-sureties to the Underwriting, Continuing Indemnity and Security Agreement, dated as of March 14, 2005, among Quanta and the subsidiaries and affiliates of Quanta identified therein and Federal (the “Underwriting Agreement”). In addition, the Joinder Agreement amends the Underwriting Agreement in certain respects, including by dispensing with the previously required $10 million letter of credit posted by Quanta as additional security for its obligations under the Underwriting Agreement. The foregoing summary of some of the terms of the Joinder Agreement is qualified in its entirety by reference to the complete text thereof, a copy of which is filed as an exhibit to this report and is incorporated herein by reference. The Underwriting Agreement was previously filed as Exhibit 10.1 to the Company’s Form 8-K on March 16, 2005.
