FORM OF EXECUTIVE STOCK OPTION GRANT NOTICE [2012]

 EXHIBIT 10.4 

LIST OF CERTAIN BENEFITS 
 AVAILABLE TO CERTAIN EXECUTIVE OFFICERS 
 (As in effect April 16,
2012) 
 The following benefits are available to some or all executive officers (among other persons), but not to all full-time employees of
the Corporation. 
  

	 	1)	If the Board has authorized a stock repurchase program, an executive may request the repurchase of shares of the Corporation at the day’s volume-weighted average
price with no payment of any fees or commissions if the repurchase of the shares is otherwise permissible under the authorized program. 

  

	 	2)	The Corporation’s regular disability insurance program is available to employees generally. Employees above a certain grade level, including executive officers,
are offered an additional benefit. Executive officers who choose the additional coverage pay the premiums with after-tax dollars. 

  

	 	3)	The Corporation makes available or pays for tax preparation, tax consulting, estate planning, and financial counseling services for executive officers. If a preferred
provider is used, the Corporation will pay the annual counseling fee ($13,500 for 2012) per person as well as general engagement fees and expenses which are not applied on a per person basis. If an executive chooses to use another provider, the
Corporation will reimburse actual costs up to the following limits: $15,000 per year for the CEO ($22,500 in any year in which a new financial counseling firm is engaged); and $5,000 per year for other executives ($7,500 in any year in which a new
financial counseling firm is engaged). 

  

	 	4)	On occasion spouses of certain employees, including executive officers, are asked by the Corporation, for business reasons, to accompany the employee on a business trip
or function. In those cases the Corporation may pay the travel, accommodation, and other expenses of the spouse incidental to the trip or function, some or all of which can result in taxable income for the employee. Also, on occasion the Corporation
may provide or pay for a memento, gift, or other gratuity that the employee or spouse receives in connection with the business trip or function. 

  

	 	5)	The Corporation provides a relocation benefit to a wide range of employees, including executive officers, under varying circumstances and subject to certain
constraints. The benefit may be in the form of an allowance or a reimbursement of actual expenses, and includes a tax gross up feature. 

  

	 	6)	The Corporation requires the Chief Executive Officer to participate in an executive health program selected by the Corporation. The program provides substantially
enhanced ongoing health screening and related services. The Corporation pays the expenses associated with attendance, including program fees and incidental expenses such as lodging, meals, and air travel. The program primarily performs screening and
diagnostic functions. Accordingly, any treatments that might be recommended as a result of the program generally would be paid in the ordinary course through the health insurance plan selected by the Officer under the Corporation’s broad-based
employee health benefit program.Joinder and Fifth Amendment to Underwriting, Continuing Indemnity and Security

 7. Amendments. By executing and delivering this Amendment, Federal, AIG, Liberty Mutual, the Company, and each other Indemnitor hereby agrees that, effective as of the date of this Amendment, the
Underwriting Agreement is hereby amended as follows: 
 (a) The Underwriting Agreement is hereby amended by adding the following
new Section 54 immediately following Section 53 of the Underwriting Agreement: 
 54. Collateral
Release. Notwithstanding anything in this Agreement or any other Surety Credit Document to the contrary, subject to prior or concurrent release by Bank of America, N.A., as Administrative Agent (the “Administrative Agent”) for the
lenders under that certain Second Amended and Restated Credit Agreement, dated as of August 2, 2011, as amended, modified, supplemented and extended from time to time (including, without limitation, any renewals, restatements and replacements
thereof) (the “Second Amended and Restated Credit Agreement”), among the Administrative Agent, 

  
 3 

 
such lenders, Quanta Services, Inc. and its subsidiaries party thereto, of the Administrative Agent’s liens and security interests granted pursuant to the Collateral Documents (as such term
is defined in the Second Amended and Restated Credit Agreement), upon notice from Quanta Services, Inc., on the first date (the “Release Date”) on which the corporate credit rating of Quanta Services, Inc. is BBB- (stable) or higher by
Standard & Poor’s Ratings Services, a division of The McGraw Hill Companies, Inc. and any successor thereto (“S&P”), and the corporate family rating of Quanta Services, Inc. is Baa3 (stable) or higher by Moody’s
Investors Service, Inc. and any successor thereto (“Moody’s”), so long as no default or Event of Default exists on such date or immediately after giving effect to the release of liens contemplated hereby, any and all liens and
security interests (including, without limitation, all Liens (as such term is defined in this Agreement) created by or arising in connection with this Agreement or any other Surety Credit Document shall automatically and immediately be fully
released and all Collateral shall automatically and immediately be released from all such liens, all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral or any other collateral or property
constituting such a lien or subject to any such lien shall terminate and revert to the Indemnitors (the “Collateral Release”). At the request and sole expense of any Indemnitor following any such release, the Surety shall deliver to such
Indemnitor any Collateral or other such property held by the Surety under any Surety Credit Document, and execute and deliver to such Indemnitor such documents as such Indemnitor shall reasonably request to evidence such release. In the event Surety
requires Indemnitors to execute such documents, promptly, and in any event within 60 days (or such longer period as is reasonably acceptable to the Surety) after notice to Quanta Services, Inc. from the Surety following the first date after the
Release Date on which the corporate credit rating of Quanta Services, Inc. by S&P falls below BBB- or the corporate family rating of Quanta Services, Inc. by Moody’s falls below Baa3, the Indemnitors shall (i) execute and deliver to
the Surety security documents, in form and substance reasonably satisfactory to the Surety, pursuant to which the Indemnitors shall grant to the Surety a security interest in all property (and types of property) then owned or held by such Person
that constituted Collateral under the Surety Credit Documents as in effect immediately prior to the Release Date and (ii) take such actions as shall be necessary or reasonably requested by the Surety to grant and perfect such Liens all at the
expense of the Indemnitors (a “Collateral Reinstatement”). Without limiting the generality of the foregoing and except as provided in the following sentence, at all times after any Release Date and prior to consummation of a Collateral
Reinstatement, Section 3(e) of this Agreement shall be deemed to have been deleted and this Section 54 shall govern and control to the extent of any conflict between the other provisions of this Agreement (including, without limitation,
Section 5 of this Agreement) or the other Surety Credit Documents and this Section 54. In the event Indemnitors fail to execute and deliver to Surety the above required documents, or Surety determines that it would prefer to proceed
without these documents, then a Collateral Reinstatement will have occurred and this Section 54 will automatically be rendered null and void at such time as the corporate credit rating of Quanta Services, Inc. by S&P falls below BBB- or the
corporate family rating of Quanta Services, Inc. by Moody’s falls below Baa3 and the terms of the Surety Credit Documents will be reinstated as though this Section 54 was never added to this Agreement. Notwithstanding any provisions of
this Section 54, the 

  
 4 

 
foregoing Collateral Release will not adversely affect or modify: (x) Surety’s right to decline to execute any and all bonds in Surety’s discretion, all as further provided in
Section 3; (y) the contractual rights of Surety upon default as provided in Section 33 of this Agreement and as provided under the Indemnity Agreement; and (z) Surety’s rights of equitable subrogation, which are hereby
acknowledged by Indemnitors. 
 (b) The Underwriting Agreement is hereby amended by adding the following sentence immediately
following the second sentence of the second paragraph of Section 5 of the Underwriting Agreement: 
 Indemnitors’
obligation to keep Surety’s security interest properly perfected will be deemed to have been met with respect to any Collateral in which a security interest can be perfected by the filing of a UCC financing statement if a UCC financing
statement that perfects such security interest has been filed in the required jurisdiction naming one or more of the companies that is a “Surety” as a named “secured party” on such filing. 

8. Further Instruments and Actions. The parties to this Amendment hereby agree to execute such further instruments and to take
such further action as may reasonably be necessary to carry out the intent and purpose of this Amendment and the Underwriting Agreement, as amended hereby. 
 9. Amendment. This Amendment may not be amended or modified except by a writing signed by or on behalf of each of the parties hereto. 

10. Headings. The section headings in this Amendment are included for convenience of reference only and shall not constitute a
part of this Amendment for any other purpose. 
 11. Governing Law. This Amendment shall be governed by and construed and
enforced in accordance with the laws of the State of New York (without giving effect to its conflict of laws principles). 
 12.
Ratification. The Underwriting Agreement, the other Surety Credit Documents and any other documents executed and delivered pursuant thereto or in connection therewith are each ratified and confirmed in all respects and shall remain in full
force and effect in accordance with their respective terms, as modified by this Amendment. 
 13. Entire Agreement. This
Amendment, together with the Underwriting Agreement and the other Surety Credit Documents, represent the entire agreement between the parties hereto concerning the subject matter hereof, and all oral discussions and prior agreements are merged
herein. 
 14. Severability. Should any provision of this Amendment be invalid or unenforceable for any reason, the
remaining provisions hereof will remain in full effect. 

  
 5 

 15. Binding Agreement. This Amendment, and the terms, covenants and conditions
hereof, will be binding upon the parties hereto and their respective successors and assigns, and will inure to the benefit of the parties, and their respective successors and permitted assigns. 

16. Counterparts. This Amendment may be executed in multiple counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. A facsimile copy of an executed original counterpart of this Amendment shall have the same force and effect as an executed original counterpart.
