Item 5. Other Events

     On October 15, 2002, Quanta Services, Inc., a Delaware corporation
("Quanta"), entered into a Securities Purchase Agreement (the "Purchase
Agreement") and an Investor's Rights Agreement (the "Investor's Rights
Agreement") with First Reserve Fund IX, L.P., a Delaware limited partnership
("First Reserve"). Also on October 15, 2002, Quanta entered into a Consent
Letter (the "Consent Letter") with Aquila, Inc. ("Aquila"). Copies of the
Purchase Agreement, Investor's Rights Agreement and Consent Letter are attached
to this filing as exhibits and are incorporated herein by reference.

     On October 15, 2002, Quanta issued a press release announcing, among other
matters, the signing of the Purchase Agreement, Investor's Rights Agreement and
Consent Letter and the purchase of common stock by First Reserve pursuant to the
Purchase Agreement. A copy of the press release is attached to this filing as an
exhibit and is incorporated herein by reference.

     Under the Purchase Agreement, on October 15, 2002, First Reserve purchased
8,666,666 shares of common stock from Quanta at a purchase price of $3.00 per
share. In addition, First Reserve agreed, subject to certain conditions, to
purchase from Quanta 2,430,741 shares of Series E Preferred Stock. Each share of
Series E Preferred Stock will, upon stockholder approval, be convertible into
ten shares of common stock, at a price per common stock share equivalent of not
less than $3.00 nor more than $3.50, depending on the average closing price of
Quanta's common stock for a designated period of time prior to closing. The
purchase of the Series E Preferred Stock by First Reserve is subject to the
negotiation of certain amendments to Quanta's senior credit facility and senior
secured debt agreements and to clearance under the antitrust laws. The Purchase
Agreement provides, among other things, that for a period of ten years, First
Reserve will not engage in transactions intended to reduce its risk of owning
capital stock of Quanta. At First Reserve's request, Quanta will call a special
meeting of its stockholders before the end of 2002 to recommend the approval of
conversion rights of the Series E Preferred Stock and the issuance of the shares
of common stock upon conversion. If Quanta's stockholders do not approve these
matters, First Reserve may repeat its request and Quanta will repeat its
recommendation to stockholders at each annual meeting of stockholders until
2006.

     Under the Investor's Rights Agreement, First Reserve is entitled to (i)
designate up to three directors to Quanta's board of directors, depending upon
First Reserve's total ownership in Quanta and certain other conditions, (ii)
three demand registrations with respect to the common stock, (iii) unlimited
"piggyback" registrations, and (iv) a pre-emptive right to purchase shares of
common stock upon Quanta's issuance of shares to third parties. In addition,
First Reserve will not acquire and own more than 37% of the voting securities of
Quanta (assuming full conversion of the Series E Preferred Stock). The
Investor's Rights Agreement also provides that (i) First Reserve shall not
transfer any portion of its shares of Preferred Stock to any competitor of
Quanta, (ii) any transferee of shares constituting 15% or more of the voting
securities of Quanta (assuming full conversion of the Series E Preferred Stock)
must assume in writing the obligations of First Reserve under the Investor's
Rights Agreement and (iii) any permitted



                                       2




transfer will be exempt from the Stockholders' Rights Plan, provided that any
transferee owning more than 5% of the voting securities of Quanta, will not, as
a result of the transfer, own more than 37% of the voting securities of Quanta.

     Under the Consent Letter, Aquila waived certain rights and benefits as a
holder of Series A Preferred Stock and agreed and consented to (i) the
designation and issuance of Series E Preferred Stock, (ii) the increase in the
number of directors of Quanta to up to twelve members, (iii) the board of
directors maintaining a majority of independent directors, and (iv) the
registration rights granted to First Reserve.

     According to Amendment No. 29 to Aquila's Statement on Schedule 13D filed
on October 17, 2002 with the Securities and Exchange Commission, through a
privately negotiated transaction, Aquila sold to First Reserve on October 15,
2002 (a) 3,303,100 shares of common stock, at $3.00 per share, and (b) 939,380
shares of Series A Convertible Preferred Stock (convertible into 4,696,900
shares of common stock), at $3.00 per common stock share equivalent.
