Exhibit 10.21

SEVERANCE AGREEMENT

AND GENERAL RELEASE OF ALL

CLAIMS

This Severance Agreement and Release of All Claims (the “Agreement”) is made and
entered into by and between Eric B. Brown (hereinafter referred to as the
“Employee”) and Quanta Services, Inc., a Delaware corporation, (hereinafter
collectively referred to as the “Company”).

The purpose of this Agreement is to arrange a settlement of the Employee’s
employment with the Company that is satisfactory both to the Company and to the
Employee. By signing this Agreement, the Company and the Employee agree as
follows:

 

1. Termination of Employment. The Employee and the Company are entering into
this Agreement as a way of amicably concluding the employment relationship
between them on September 15, 2014 (“Separation Date”), and of resolving
voluntarily any dispute or potential dispute or claim that the Employee has or
might have with the Company, whether known or unknown by the Employee at this
time. This Agreement is not and should not be construed as an allegation by
Employee, or as an admission on the part of the Company, that the Company has
acted unlawfully or violated any state or federal law or regulation. The
Company, including its parent companies, affiliates, associated companies, and
subsidiaries, specifically disclaim any liability to the Employee or any other
person for any alleged violation of rights or for any alleged violation of any
order, law, statute, duty, policy or contract.

 

2. Severance Benefits. As consideration for the Employee agreeing to release the
Company from all claims and liabilities that are described in Paragraph 6 herein
and subject to the provisions of Paragraph 10 herein, the Company will pay
Employee the following as severance benefits (the “Severance Benefits”):

 

  a. a lump sum, equal to nine (9) months of Employee’s base salary, in the
amount of Two Hundred Ninety Two Thousand Five Hundred Dollars ($292,500), less
applicable taxes and authorized withholdings, with such amount to be paid within
ten (10) days after the expiration of the period for Employee to revoke his
acceptance to this Agreement under Paragraph 9, but in no event later than
November 15, 2014; and

 

  b.

a lump sum amount equal to Employee’s 2014 annual cash bonus, pro rated from
January 1, 2014 through the Separation Date. The amount of the bonus will be
established on or around February 28, 2015, in accordance with the Company’s
customary practice for setting bonus amounts, and will be paid to Employee in a
lump sum, less applicable taxes and authorized withholdings, within ten
(10) days after the date the bonus amount is set, but in no event later than
March 15, 2015.

--------------------------------------------------------------------------------

  For purposes of pro-rating the bonus, Employee’s annual bonus amount shall be
multiplied by 70.7% to pro-rate the bonus for the period of January 1, 2014
through the Separation Date.

Each payment payable under this Agreement is intended to be exempt from or
compliant with Section 409A of Internal Revenue Code and constitutes a separate
payment for purposes of Section 409A of the Internal Revenue Code. The timing of
payment pursuant to this Paragraph shall be determined as established herein and
Employee may not designate the time of payment of any of the Severance Benefits.

 

3. Entire Consideration. The Employee agrees that the Severance Benefits set
forth in Paragraph 2, herein, constitute the entire amount of consideration
provided to him under this Agreement. The Employee further agrees that he will
make no claim for any additional or other severance benefits or payments and
that he will not seek any further compensation for any other claimed damage,
costs, severance, income or attorneys’ fees.

 

4. Nondisclosure Agreement. Without the express written agreement of the
Company’s Chief Executive Officer, or unless required to do so by law, the
Employee agrees never to disclose the existence, facts, terms, or amounts paid
under this Agreement, nor the substance of the negotiations leading to this
Agreement, to any person or entity, other than to his personal counsel or
attorney, personal accountants, or personal tax preparer, any such disclosure to
such persons to be made only if the relevant person must have such information
for the performance of his or her responsibilities. To the extent required by
law or applicable regulation, Employee may also disclose the provisions of this
Agreement to the appropriate taxing or regulatory authorities. If Employee
receives a subpoena or other request for documents in a legal proceeding calling
for production of this Agreement, Employee will immediately notify the Employer
(to the attention of the Company’s General Counsel or Chief Executive Officer)
of such subpoena or request, so that the Company may determine whether to assert
objections or seek legal relief to prevent disclosure of this Agreement.

 

5.

The Employee’s Release Of All Claims Including Age Discrimination In Employment
Act Claims. In consideration of the Severance Benefits, the Employee, for
himself, his heirs, executors, administrators, successors and assigns, does
fully and forever release and discharge the Company, its parent companies,
affiliates, associated companies, and subsidiaries, their respective associated
companies and subsidiaries, all of their respective present and former officers,
directors, supervisors, managers, employees, stockholders, agents, attorneys and
representatives, and the successors and assigns of such persons and entities
(collectively, the “Released Parties”), from all actions, lawsuits, grievances,
complaints, liens, demands, obligations, damages, liabilities, and claims of any
nature whatsoever, know or unknown, that the Employee had, now has, or may
hereafter claim to have against the Released Parties from the beginning of time
through the date the Employee executes this Agreement. The release provided
herein specifically includes, but is not limited to, all claims arising under
any federal, state or local fair employment practice laws, and any other
employee relations statute, executive order, law and ordinance, including, but
not limited to, Title VII of the Civil Rights Acts of 1964, as amended; the
Civil Rights Acts of 1866, 1870, and 1871, as

 

2

--------------------------------------------------------------------------------

  amended; the Civil Rights Act of 1991, as amended; the Age Discrimination in
Employment Act of 1967, as amended; the Older Workers Benefit Protection Act, as
amended; the Americans With Disabilities Act of 1990, as amended; the Family and
Medical Leave Act, as amended; the Equal Pay Act, as amended; the Fair Labor
Standards Act, as amended; the Worker Adjustment and Retraining Notification Act
of 1988, as amended; the Employee Retirement Income Security Act of 1974, as
amended; Section 806 of the Sarbanes-Oxley Act of 2002 (18 U.S.C. §1514A, et
seq.); the Rehabilitation Act of 1973 (29 U.S.C. Section 791 et seq.); the
Occupational Safety and Health Act (29 U.S.C. § 651, et seq.); the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended (COBRA); the Texas Labor
Code, as amended; the Texas Administrative Code, as amended; the Texas
Commission on Human Rights Act, as amended; any local human rights law; and any
tort or contract cause of action or theory.

The Employee expressly represents and agrees that he has been advised that, by
entering into this Agreement, he is waiving all claims that he may have against
the Company arising under the Age Discrimination in Employment Act of 1967, as
amended, which have arisen on or before the date of execution of this Agreement.

 

6. Covenants Concerning Claims/Limitations on Scope of Agreement. The Employee
agrees that he will not file any complaints, claims or actions against the
Released Parties with any court regarding any matters or claims that arose prior
to the Employee’s execution of this Agreement. If any court assumes jurisdiction
on behalf of the Employee of any complaint, claim or action against the Company,
he will direct that court to withdraw from or dismiss with prejudice the matter.

Notwithstanding the preceding provision or any other provision of the Agreement,
Employee’s agreement to the provisions under Paragraph 5, or any other section
of this Agreement, is not intended to prohibit Employee from bringing an action
to challenge the validity of the release of claims under the Age Discrimination
in Employment Act, as amended, or the Older Worker’s Benefit Protection Act, as
amended. The Employee further understands and agrees that if he or someone
acting on his behalf files, or causes to be filed, any such claim, charge,
complaint, or action against the Released Parties, he expressly waives any right
to recover any damages or other relief, whatsoever, from the Released Parties,
including costs and attorneys’ fees.

Nothing in this Agreement is intended to, or will, interfere with Employee’s
right to file a charge with, provide information to, cooperate with, or
participate in an investigation or administrative proceeding conducted by the
Equal Employment Opportunity Commission or state fair employment practices
agency, or by any other federal or state regulatory or law enforcement agency or
commission. However, by executing this Agreement, Employee hereby waives the
right to recover, and agrees not to seek any damages, remedies or other relief
for himself personally in any proceeding he may bring before such agency or in
any proceeding brought by such agency, or any other person, on his behalf. This
Agreement is also not intended to apply to claims for accrued benefits (other
than severance-type benefits) under any benefit plan of the Released Parties
pursuant to the terms of any such plan.

--------------------------------------------------------------------------------

Employee understands that he is not releasing rights under this Agreement that
cannot be waived as a matter of law, that any claims that cannot be lawfully
waived are excluded from this Agreement, and that by executing this Agreement he
is not waiving any such claims. Likewise, Employee is not releasing any rights
or claims that may arise after the date on which he signs this Agreement
including but not limited to rights under the Indemnity Agreement dated
February 20, 2014. In addition, while this Agreement requires Employee to waive
any and all claims against the Released Parties arising under workers’
compensation laws (e.g., claims of retaliation for filing a workers’
compensation claim), it is not intended to prohibit Employee from filing in good
faith for and from receiving any workers’ compensation benefits from Released
Parties’ workers’ compensation carrier for compensable injuries incurred during
his employment. Accordingly, pursuit of any such workers’ compensation benefits
with Released Parties’ workers’ compensation carrier or third-party
administrator will not be considered a violation of this Agreement.

 

7. Employee Acknowledgments. Employee acknowledges and agrees that:

 

  a. In return for and in consideration of his execution, delivery and

Severance Benefits.

provided at least twenty-one (21) days to consider whether to sign this
Agreement. If the Employee signs this Agreement prior to the end of the 21-day

time is knowing and voluntary. Should the Employee sign this Agreement before
the expiration of the 21-day period, the Company may at its option and
discretion expedite the processing of some or all of the Severance Benefits,
subject to the revocation period set forth in Paragraph 9.

 

9. Seven (7) Day Revocation Period. The Employee understands that he may revoke
this Agreement at any time within seven (7) days after he executes it. To revoke

to Employer’s CEO, James F. O’Neil, III, or in his absence, to Chief Operating
Officer Earl C. Austin, Jr., within seven (7) days after the date of the

he does not revoke the Agreement within seven (7) days following its execution
(excluding the date of execution), it will become effective, binding, and
