         THIS ELEVENTH AMENDMENT TO THIRD AMENDED AND RESTATED SECURED CREDIT
AGREEMENT (this "Amendment"), dated as of October 9, 2003, is entered into among
QUANTA SERVICES, INC., a Delaware corporation (the "Borrower"), the Lenders
(defined below) who are signatories hereto, and BANK OF AMERICA, N.A., as
administrative agent for the Lenders (in such capacity, the "Agent").
Capitalized terms used but not defined in this Amendment have the meaning given
them in the Credit Agreement (defined below).

                                   BACKGROUND

         A. The Borrower is party to that certain Third Amended and Restated
Secured Credit Agreement dated as of June 14, 1999 (as amended through the date
hereof and as may be further amended, restated or supplemented from time to
time, the "Credit Agreement"), among the Borrower, the Agent, and the lenders
from time to time party to the Credit Agreement (each a "Lender" and
collectively, the "Lenders").

         B. The Borrower, Majority Lenders and the Agent desire to make certain
amendments to the Credit Agreement.

         NOW, THEREFORE, in consideration of the covenants, conditions and
agreements hereinafter set forth, and for other good and valuable consideration,
the receipt and adequacy of which are all hereby acknowledged, the Borrower,
Majority Lenders and the Agent covenant and agree as follows:

         1. AMENDMENTS TO CREDIT AGREEMENT. The Credit Agreement is hereby
amended as follows:

              (a) Amendment to Section 6.10(a). Clause (a) of Section 6.10 is
         amended by adding a new sentence at the end thereto to read as follows:

              The amount of payments permitted pursuant to the foregoing clauses
              (D) and (E) shall be deemed to include the $15,000,000 which the
              Borrower is permitted to retain from the net offering proceeds in
              accordance with Section 2.10(c).

              (b) Amendment to Section 6.14. Section 6.14(i) is amended and
         restated in its entirety, as follows:

                           (i) Indebtedness not to exceed $275,000,000 at any
                  time under the 2003 Note Purchase Agreement, including without
                  limitation, the Indebtedness under the 2003 Convertible
                  Subordinated Notes; provided that, such Indebtedness is
                  unsecured and upon terms not materially less favorable than
                  the terms of the Convertible Subordinated Notes and is
                  otherwise on terms reasonably satisfactory to the Agent,
                  including without limitation ranking subordination terms at
                  least as favorable to the Lenders as those contained in the
                  Convertible Subordinated



                  Notes, and provided further that all net cash proceeds from
                  the issuance of such Indebtedness are applied in accordance
                  with SECTION 2.10(C) of this Agreement, which contemplates
                  that such net cash proceeds in excess of $15,000,000 (which
                  $15,000,000 the Borrower is permitted to retain consistent
                  with Section 2.10(c)) will be allocated to the Lenders and to
                  the holders of the Senior Notes (based on the proportion of
                  the Commitment Amount under this Agreement and the proportion
                  of the outstanding principal amount of the Senior Notes to
                  the sum of both) and applied as follows: (A) with respect to
                  the proceeds allocated to the Lenders, paid to the Agent as
                  a prepayment of the Loans, and if all Loans have been
                  satisfied, to the Agent as cash collateral for the
                  outstanding L/C Obligations (which security interest shall
                  be expressly senior to any security interest in
                  such cash collateral which secures the Senior Notes),
                  in each case together with a corresponding, automatic
                  and permanent reduction of the Commitment Amount by the amount
                  of net proceeds that would be allocated to the Lenders if the
                  Loans and L/C Obligations exceeded such amount of net proceeds
                  (and not any lesser amount which may ultimately be allocated
                  to the Lenders if the Loans and L/C Obligations are less than
                  such amount of net proceeds), and if all of the L/C
                  Obligations have been so cash collateralized, to the holders
                  of the Senior Notes to be applied in accordance with Section
                  8.8(e) of the Note Purchase Agreement, and (B) with respect to
                  the proceeds allocated to the holders of the Senior Notes,
                  paid to such holders to be applied in accordance with Section
                  8.8(e) of the Note Purchase Agreement; and

              (c) Notwithstanding anything in this Agreement to the contrary,
         the Borrower shall be permitted to disregard any Make-Whole Amount (as
         defined in the Note Purchase Agreement) paid or required to be paid as
         a result of or in connection with the 2003 Note Purchase Agreement or
         any offering or issuance of the 2003 Convertible Subordinated Notes for
         purposes of any determination of the Borrower's compliance with any
         covenant contained in Section 6.20, 6.21, 6.22, 6.23 or 6.24 of this
         Agreement.

         2. REPRESENTATIONS AND WARRANTIES. Each of the Borrower and the
Guarantors represents and warrants to the Lenders that (a) it possesses all
requisite power and authority to execute, deliver and comply with the terms of

it is in full compliance with all covenants and agreements contained in each
Credit Document to which it is a party, and (g) no Default or Event of Default

         irrevocably remises, acquits, and fully and forever releases and
         discharges the Agent and the Lenders


                                       2

         Lenders, their respective officers, servants, employees, agents,
         attorneys, financial advisors, principals, directors and shareholders,
         and their respective heirs, legal representatives, successors and

         claims, demands, causes of action, obligations, remedies, suits,
         damages and liabilities (collectively, the "Borrower Claims") of any
         nature whatsoever, whether now known, suspected or claimed, whether
         arising under common law, in equity or under statute, which the
         Borrower or any Guarantor ever had or now has against the Released
         Lender Parties which may have arisen at any time on or prior to the
         date of this Amendment and which were in any manner related to any of
         the Credit Documents or the enforcement or attempted enforcement by the
         Agent or the Lenders of rights, remedies or recourses related thereto.

              (b) The Borrower and each Guarantor covenants and agrees never to
         commence, voluntarily aid in any way, prosecute or cause to be
         commenced or prosecuted against any of the Released Lender Parties any
         action or other proceeding based upon any of the Borrower Claims which
         may have arisen at any time on or prior to the date of this Amendment
         and were in any manner related to any of the Credit Documents.
