Who is entitled to vote at the meeting?

Only holders of record of (A) our Common Stock, par value $0.00001 per share, (B) our Limited Vote Common Stock, par value $0.00001 per share, and (C) our Series F Preferred Stock, par value $0.00001 per share, respectively, at the close of business on March 21, 2011, the record date for the meeting, are entitled to notice of and to vote at the annual meeting. If you were a stockholder of record on that date, you will be entitled to vote all of the shares that you held on that date at the meeting, or at any adjournments or postponements of the meeting unless a new record date is then set.

As of March 21, 2011,              shares of our Common Stock, 432,485 shares of our Limited Vote Common Stock, and one share of our Series F Preferred Stock, respectively, were outstanding and entitled to vote. In addition, on March 21, 2011, we had 3,909,110 shares of Common Stock reserved for issuance upon the exchange of Class A non-voting exchangeable common shares of Valard Construction Ltd., a British Columbia company and successor to Quanta Services EC Canada Ltd., which are not entitled to vote at the meeting.

What are the voting rights of the holders of Common Stock, Limited Vote Common Stock and Series F Preferred Stock?

Each share of Common Stock is entitled to one vote on each matter on which it may vote. Each share of Limited Vote Common Stock is entitled to one vote on the election of one director and to one-tenth of one vote on each other matter on which it may vote. The share of Series F Preferred Stock is entitled to the number of votes equal to the number of outstanding shares, as of March 21, 2011, of Class A non-voting exchangeable common shares of Valard Construction Ltd., a British Columbia company and successor to Quanta Services EC Canada Ltd., on each matter on which it may vote.

With respect to the election of directors, holders of Common Stock and the Series F Preferred Stock, voting together as a single class, will elect ten directors. Holders of Limited Vote Common Stock, voting separately as a class, will elect one director. On all matters other than the election of directors, holders of Common Stock, Limited Vote Common Stock and Series F Preferred Stock will vote together as a single class. The required vote to approve each item to be voted on at the meeting is described below.

Who can attend the meeting?

All stockholders of record as of March 21, 2011, or their duly appointed proxies, may attend the meeting, and each may be accompanied by one guest. Seating, however, is limited. Admission to the meeting will be on a first-come, first-served basis. Registration will begin at 8:00 a.m. and seating will begin at 8:30 a.m. Each stockholder will be asked to present valid picture identification, such as a driver’s license or passport. Cameras, recording devices and other electronic devices will not be permitted at the meeting. To obtain directions to be able to attend the meeting and vote in person, please contact our Corporate Secretary at 713-629-7600.

Please note that if you hold your shares in “street name” (that is, through a broker or other nominee), you will need to bring a copy of a brokerage statement reflecting your stock ownership as of the record date and check in at the registration desk at the meeting.

What constitutes a quorum?

In order to transact any business at the meeting, the holders of a majority of the aggregate outstanding shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock entitled to vote must be present, in person or by proxy, to constitute a quorum for the meeting. The following additional quorum requirements must also be satisfied to transact the specified business at the meeting:

With respect to the election of directors by the holders of Common Stock and Series F Preferred Stock, holders of shares representing a majority of the voting power of the outstanding Common Stock and outstanding Series F Preferred Stock entitled to vote must be present, in person or by proxy, to constitute a quorum for such election.

With respect to the election of directors by the holders of Limited Vote Common Stock, holders of a majority of the outstanding shares of Limited Vote Common Stock entitled to vote must be present, in person or by proxy, to constitute a quorum for such election.

With respect to the Share Increase Amendment, holders of a majority of the outstanding shares of Common Stock entitled to vote must be present, in person or by proxy, to constitute a quorum for adoption of the Share Increase Amendment.

With respect to the Reclassification Amendment, holders of a majority of the outstanding shares of Limited Vote Common Stock entitled to vote must be present, in person or by proxy, to constitute a quorum for adoption of the Reclassification Amendment.

As of March 21, 2011,              shares of our Common Stock with aggregate voting power of              votes, 432,485 shares of our Limited Vote Common Stock with aggregate voting power of 432,485 votes with regard to the election of one director and aggregate voting power of 43,249 votes on all other matters, and one share of our Series F Preferred Stock with aggregate voting power of 3,909,110 votes, respectively, were outstanding and entitled to vote. Properly executed proxies received but marked as abstentions and broker non-votes will be counted for purposes of establishing a quorum at the meeting.

What vote is required to approve each item to be voted on at the meeting?

Directors are elected by a majority of the votes cast with respect to such director in uncontested elections, such that a nominee for director will be elected to the Board if the votes cast FOR the nominee’s election exceed the votes cast AGAINST such nominee’s election. Abstentions and broker non-votes are not counted for purposes of the election of directors and, therefore, will have no effect on the outcome of such election. Even if a nominee is not re-elected, he or she will remain in office as a director until his or her earlier resignation or removal. Each of the current director nominees has signed a letter of resignation that will be effective if the

3

nominee is not re-elected at the meeting and the Board accepts his or resignation following the meeting. If a nominee is not re-elected, the Board will decide whether to accept the director’s resignation in accordance with the procedures listed in Quanta’s Corporate Governance Guidelines, which are available on our website at www.quantaservices.com.

Adoption of the Share Increase Amendment to Quanta’s Certificate of Incorporation requires (i) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, and (ii) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, voting as a separate class. Abstentions and broker non-votes will have the same effect as a vote against such proposal.

Adoption of the Reclassification Amendment to Quanta’s Certificate of Incorporation requires (i) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, and (ii) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Limited Vote Common Stock, voting as a separate class. Abstentions and broker non-votes will have the same effect as a vote against such proposal.

Adoption of the Miscellaneous Amendment to Quanta’s Certificate of Incorporation requires the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class. Abstentions and broker non-votes will have the same effect as a vote against such proposal.

Approval of the Quanta Services, Inc. 2011 Omnibus Equity Incentive Plan requires the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, casting a vote on that proposal; provided that the voting power of the shares casting a vote represents over 50% of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, entitled to vote on that proposal. Abstentions will have the same effect as a vote against such proposal. Broker non-votes will have no effect on the outcome of the vote on such proposal.

Ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm requires the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, present at the meeting in person or by proxy and entitled to vote on that proposal. Abstentions will have the same effect as a vote against the proposal. Broker non-votes will have no effect on the outcome of the vote on such proposal.

Approval of the advisory resolution on Quanta’s executive compensation requires the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, present at the meeting in person or by proxy and entitled to vote on that proposal. Abstentions will have the same effect as a vote against the advisory resolution. Broker non-votes will have no effect on the outcome of the advisory vote. The results of this vote are not binding on the Board, whether or not the proposal is adopted by the aforementioned voting standard. In evaluating the vote on this advisory resolution, the Board intends to consider the voting results in their entirety.

With respect to the advisory vote on the frequency of future advisory votes on Quanta’s executive compensation, the voting option (1 year, 2 years or 3 years), if any, that receives the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, present at the meeting in person or by proxy and entitled to vote on that proposal will be adopted by the stockholders, in accordance with Quanta’s Bylaws. Abstentions will have the same effect as a vote against each of the voting options. Broker non-votes will have no effect on the outcome of the advisory vote. The results of this vote are not binding on the Board, whether or not it is adopted

4

by the aforementioned voting standard. In evaluating the vote on this advisory resolution, the Board will consider the voting results in their entirety. If one of the voting options is not adopted by the required vote of the stockholders, the Board will evaluate the votes cast for each of the voting options and will deem the voting option receiving the greatest number of votes to be the voting option approved by the stockholders.

Any other matter properly brought before the meeting will be decided by the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, present at the meeting in person or by proxy and entitled to vote on the matter.

How do I vote?

You may vote your shares in any of the following manners:

• by signing and dating the enclosed proxy card and returning it in the accompanying envelope;

• if you hold your shares through a broker, by going to the website www.proxyvote.com, with your proxy card in hand, and following the instructions (not available to holders of Limited Vote Common Stock or Series F Preferred Stock);

• if you hold your shares through a broker, by telephone following the instructions included with your proxy card (not available to holders of Limited Vote Common Stock or Series F Preferred Stock); or

• by written ballot at the meeting.

If you are a stockholder of record and you attend the meeting, you may deliver your completed proxy card in person. If you hold your shares in “street name” and you wish to vote at the meeting, you will need to obtain a proxy from the broker or nominee that holds your shares.

Whether or not you plan to attend the meeting, we encourage you to vote by proxy as soon as possible.

What is the difference between holding shares as a stockholder of record and in “street name”?

Many stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. This is often called holding shares in “street name.” As summarized below, there are some distinctions between record stockholders and “street name” holders.

If your shares are registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, you are considered the stockholder of record for those shares, and these proxy materials are being sent directly to you.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of those shares, and you hold your shares in “street name.” In this case, proxy materials are being forwarded to you by your broker or nominee. As the beneficial owner, you have the right to direct your broker how to vote and are also invited to attend the annual meeting. However, because you are not a stockholder of record, you may not vote these shares in person at the annual meeting unless you bring with you a proxy from your broker or nominee. Your broker, bank or nominee has enclosed a voting instruction card for you to use in directing the vote of your shares.

What are broker non-votes?

The New York Stock Exchange (“NYSE”) permits brokers to vote their customers’ stock held in street name on routine matters, such as the ratification of the appointment of our independent registered public accounting firm, when the brokers have not received voting instructions from their customers. However, the

5

NYSE does not allow brokers to vote their customers’ stock held in street name on non-routine matters unless they have received voting instructions from their customers. In such cases, the uninstructed shares for which the broker is unable to vote are called broker non-votes.

What routine matters will be voted on at the meeting?

Ratification of the appointment of our independent registered public accounting firm is the only matter to be voted on at the meeting on which brokers may vote in their discretion on behalf of customers who have not provided voting instructions.

What non-routine matters will be voted on at the meeting?

Each of the election of directors, the Share Increase Amendment, the Reclassification Amendment, the Miscellaneous Amendment, approval of the 2011 Omnibus Equity Incentive Plan, the advisory vote on executive compensation, and the advisory vote recommending the frequency of future advisory votes on executive compensation is a non-routine matter on which brokers are not allowed to vote unless they have received voting instructions from their customers.

What is the effect of not casting a vote?

If you are a stockholder of record and you do not cast your vote, no votes will be cast on your behalf on any of the matters that properly come before the meeting.

If you hold your shares through a broker, bank or other nominee, it is critical that you cast your vote if you want it to count in the election of directors and most of the other matters to be voted on at the meeting. In prior years, if you held your shares through a broker, bank or other nominee, and you did not indicate how you wanted your shares voted in the election of directors, your broker, bank or other nominee was allowed to vote those shares on your behalf in the election of directors as they felt appropriate. However, recent NYSE rule changes have eliminated the ability of your broker, bank or other nominee to vote your uninstructed shares in the election of directors on a discretionary basis. Thus, if you hold your shares through a broker, bank or other nominee, and you do not instruct your broker, bank or other nominee how to vote in the election of directors or any other non-routine matter, no votes will be cast on your behalf on such matters. Therefore, your broker, bank or other nominee will not have discretion to vote your shares on the election of directors, the Share Increase Amendment, the Reclassification Amendment, the Miscellaneous Amendment, the 2011 Omnibus Equity Incentive Plan, the advisory vote on executive compensation, or the advisory vote recommending the frequency of future advisory votes on executive compensation, respectively, if you do not instruct your broker, bank or other nominee how to vote on these proposals, as these are not “routine” matters under NYSE rules. Your broker, bank or other nominee will, however, continue to have discretion to vote any uninstructed shares on the ratification of the appointment of our independent registered public accounting firm.

Can I change my vote after I return my proxy card?

Yes. You may change your vote at any time before the proxy is exercised, even after you have submitted your proxy card, by filing with our Corporate Secretary either a written notice of revocation or a duly executed proxy bearing a later date. The powers of the proxy holders will be revoked with respect to your shares if you attend the meeting in person and vote your shares in person by completing a written ballot. Attendance at the meeting will not by itself revoke a previously granted proxy. If you hold your shares in “street name” and you wish to change your vote at the meeting, you will need to obtain a proxy from the broker, bank or nominee that holds your shares.

What if I receive more than one proxy card?

If you hold your shares in more than one type of account or your shares are registered differently, you may receive more than one proxy card. We encourage you to vote each proxy card that you receive.

6

Where can I find the voting results of the meeting?

We plan to announce preliminary voting results at the meeting and publish final results in a Current Report on Form 8-K or an amendment thereto timely filed with the Securities and Exchange Commission.

(1) The percent of class beneficially owned is calculated based on (A) 211,174,544 shares of our Common Stock, with aggregate voting power of an equal number of votes, (B) 432,485 shares of our Limited Vote Common Stock, with aggregate voting power of an equal number of votes with respect to the election of one director and 43,249 votes with respect to all matters other than the election of directors, and (C) one share of our Series F Preferred Stock, with aggregate voting power of 3,909,110 votes, respectively, issued and outstanding as of March 10, 2011.

CORPORATE GOVERNANCE

We are committed to having sound corporate governance practices that maximize stockholder value in a manner consistent with legal requirements and the highest standard of integrity. In that regard, the Board has adopted guidelines that provide a framework for the governance of Quanta. In addition, we continually review these guidelines and regularly monitor developments in the area of corporate governance. Our Corporate Governance Guidelines are posted on our website at www.quantaservices.com under the heading “Corporate Governance.”

Board Independence

The Board has determined that Messrs. Ball, Conaway, DiSibio, Foster, Fried, Golm, Jackman, Ranck and Wood have no material relationship with Quanta (either directly or as a partner, shareholder or officer of an organization that has a relationship with Quanta) and are “independent” within the meaning of the NYSE’s corporate governance listing standards. The Board has made this determination based on its finding that these independent directors meet the categorical standards for director independence set forth in our Corporate Governance Guidelines and in the NYSE corporate governance listing standards. Our Corporate Governance Guidelines, which include our categorical standards for director independence, are posted on our website at www.quantaservices.com under the heading “Corporate Governance.”

Board Leadership Structure

The Board believes that Quanta’s Chief Executive Officer is best situated to serve as Chairman of the Board because he possesses detailed and in-depth knowledge of the issues, opportunities and challenges facing Quanta and its business and is thus best positioned to develop agendas that ensure that the Board’s time and attention are focused on the most critical matters. The Board believes that the combined role of Chairman and Chief Executive Officer promotes strategy development and execution and fosters decisive leadership, clear accountability and effective decision-making. The Board believes that it has in place sound counter-balancing measures to ensure that Quanta maintains high standards of corporate governance and proper independent oversight. For instance, the Board holds executive sessions of the independent directors at every regularly scheduled Board meeting and, with nine of the Board’s eleven directors deemed independent, maintains a percentage of independent directors serving on the Board that is substantially above the NYSE requirement that a majority of directors be independent. In addition, the Board, through its independent directors, has adopted the position of a lead independent director to strengthen the independence and roles of the independent directors. The duties of the lead independent director include presiding over executive sessions or other meetings of the independent directors and consulting with the Chairman of the Board as to agenda items for Board and committee meetings. The independent directors have decided to rotate the position of lead independent director on a quarterly basis among the chairmen of the Audit, Compensation and Governance and Nominating Committees. The Board recognizes, however, that no single leadership model is right for all companies and at all times and that depending on the circumstances, other leadership models, such as a separate independent chairman of the board, may be appropriate. Accordingly, the Board annually reviews and assesses the effectiveness of its leadership structure.

The Board’s Role in Risk Oversight

The Board oversees an enterprise-wide approach to risk management, designed to support the achievement of long-term organizational objectives and enhance stockholder value. The full Board participates in an annual enterprise risk management assessment, led by Quanta’s President and Chief Operating Officer, that provides visibility to the Board about the identification, assessment and management of critical risks and management’s risk mitigation strategies. In this process, risk is assessed throughout the business, including operational, financial, legal, regulatory, strategic and reputational risks. A fundamental part of risk management is not only understanding the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the company. The involvement of the full Board in setting Quanta’s business strategy, both short- and long-term, is a key part of its understanding of Quanta’s risks and

16

what constitutes an appropriate level of risk for Quanta as well as how such risks are managed. While the Board has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk management. Specifically, the Audit Committee focuses on risks relating to financial reporting, internal controls and compliance with legal and regulatory requirements. In addition, the Compensation Committee focuses on risks relating to Quanta’s compensation policies and programs and, in setting compensation, strives to create incentives that are aligned with Quanta’s risk management profile. Finally, Quanta’s Governance and Nominating Committee focuses on risks relating to Quanta’s corporate governance and Board membership and structure and also conducts a quarterly assessment of the risk management process and reports its findings to the Board.

Audit Committee

The Board has examined the composition of the Audit Committee and has determined that each of the members of the Audit Committee is “independent” within the meaning of Securities and Exchange Commission (SEC) regulations, NYSE rules governing audit committees and our Corporate Governance Guidelines. The Audit Committee is established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the Exchange Act). The Audit Committee operates under a formal charter adopted by the Board that governs its responsibilities. The Audit Committee Charter is posted on our website at www.quantaservices.com under the heading “Corporate Governance.” The membership and number of meetings held during the last fiscal year and the primary responsibilities of the Audit Committee are described in “Committees of the Board” above. The Board has determined that Messrs. Conaway and Jackman are “audit committee financial experts” within the meaning of SEC regulations.

Compensation Committee

The Board has determined that each of the members of the Compensation Committee is “independent” within the meaning of NYSE corporate governance listing standards and our Corporate Governance Guidelines. The Compensation Committee operates under a formal charter adopted by the Board that governs its responsibilities. The Compensation Committee Charter is posted on our website at www.quantaservices.com under the heading “Corporate Governance.” The membership and number of meetings held during the last fiscal year and the primary responsibilities of the Compensation Committee are described in “Committees of the Board” above. For additional information on the Compensation Committee, including a description of its processes and procedures for the consideration and determination of NEO compensation, please see “Compensation Discussion and Analysis — Compensation Committee” below.

Governance and Nominating Committee

The Board has determined that each of the members of the Governance and Nominating Committee is “independent” within the meaning of NYSE corporate governance listing standards and our Corporate Governance Guidelines. The Governance and Nominating Committee operates under a formal charter adopted by the Board that governs its responsibilities. The Governance and Nominating Committee Charter is posted on our website at www.quantaservices.com under the heading “Corporate Governance.” The membership and number of meetings held during the last fiscal year and the primary responsibilities of the Governance and Nominating Committee are described in “Committees of the Board” above.

Code of Ethics and Business Conduct

The Board has adopted a Code of Ethics and Business Conduct that applies to all directors, officers and employees of Quanta and its subsidiaries, including the principal executive officer, principal financial officer and principal accounting officer or controller. The Code of Ethics and Business Conduct is posted on our website at www.quantaservices.com under the heading “Corporate Governance.” We intend to post at the above location on our website any amendments or waivers to the Code of Ethics and Business Conduct that are required to be disclosed pursuant to Item 5.05 of Form 8-K.

17

Executive Sessions of Non-Management Directors

In accordance with the NYSE corporate governance listing standards, our non-management directors, each of whom is “independent” within the meaning of NYSE corporate governance listing standards and our Corporate Governance Guidelines, meet in executive session without management at each regularly scheduled Board meeting.

Communications with the Board

Stockholders and other interested parties may communicate with one or more of our directors, including any lead independent director or our non-management directors or independent directors as a group, a committee or the full Board by writing to Corporate Secretary, Quanta Services, Inc., 2800 Post Oak Blvd., Suite 2600, Houston, Texas 77056. All communications will be reviewed by the Corporate Secretary and forwarded to one or more of our directors, as appropriate.

Director Qualifications

Our Corporate Governance Guidelines contain Board membership qualifications that the Governance and Nominating Committee considers in selecting nominees for our Board. Pursuant to these qualifications, members of the Board should possess the highest standards of personal and professional ethics, integrity and values, and be committed to representing the long-term interests of our stockholders. They must also have an inquisitive and objective perspective, practical wisdom, mature judgment, the willingness to speak their mind and the ability to challenge and stimulate management in a constructive manner. In addition, Board members should have diverse experience at policy-making levels that may include business, government, education, technology or non-profit organizations, as well as experience in areas that are relevant to our business. Further, they should have demonstrated leadership skills in the organizations with which they are or have been affiliated. Members of the Board must also be willing to devote sufficient time to carrying out their duties and responsibilities effectively and should be committed to serve on the Board for an extended period of time. The Governance and Nominating Committee also seeks directors representing a broad range of viewpoints and diverse backgrounds, including women and minorities that meet the above qualifications.

Identifying and Evaluating Nominees for Director

The Governance and Nominating Committee regularly evaluates the appropriate size of the Board and whether any vacancies on the Board are expected due to retirement or otherwise. In the event that vacancies are anticipated, or otherwise arise, the Governance and Nominating Committee will consider candidates for Board membership suggested by incumbent directors, management, third-party search firms and others. The Governance and Nominating Committee will also consider director nominations by stockholders that are made in compliance with the notice provisions and procedures set forth in our bylaws. For a discussion of these requirements, see “Additional Information — Stockholder Proposals and Nomination of Directors for the 2012 Annual Meeting” below. All applications, recommendations or proposed nominations for Board membership received by Quanta will be referred to the Governance and Nominating Committee. The manner in which the Governance and Nominating Committee evaluates the qualifications of a nominee for director does not differ if the nominee is recommended by a stockholder.

The Governance and Nominating Committee has the authority to retain a third-party search firm to help identify and facilitate the screening and interview process of potential director nominees, including screening candidates, conducting reference checks, preparing a biography of each candidate for the Governance and Nominating Committee to review and helping coordinate interviews.

Once the Governance and Nominating Committee has identified a potential director nominee, the committee makes an initial determination as to whether to conduct a full evaluation of the candidate. This initial determination is based on whatever information is provided to the committee with the recommendation of the candidate, as well as

18

the committee’s own knowledge of the candidate, which may be supplemented by inquiries to the person making the recommendation or others. The committee also may engage a third party to conduct a background check of the candidate. If the committee determines to further pursue the candidate, the committee then will evaluate the extent to which the candidate meets the Board membership qualifications described in “Director Qualifications” above.

In addition, the Governance and Nominating Committee considers other relevant factors it deems appropriate, including the current composition of the Board (including its diversity in experience, background, gender and ethnicity), the balance of management and independent directors, the need for a certain Board committee expertise, and the nature and extent of a candidate’s activities unrelated to Quanta, including service as a director on the boards of other public companies. In connection with this evaluation, the committee determines whether to interview the candidate, and, if warranted, the committee interviews the candidate in person or by telephone. The committee may also ask the candidate to meet with members of Quanta’s management or other Board members. After completing this evaluation, if the committee believes the candidate would be a valuable addition to the Board, it will recommend to the Board the candidate’s nomination for appointment or election as a director.

Director Compensation

The Governance and Nominating Committee has the responsibility of recommending to the Board compensation and benefits for non-employee directors. The committee is guided by certain director compensation principles set forth in our Corporate Governance Guidelines. Directors who also are employees of Quanta or any of its subsidiaries do not receive additional compensation for serving as directors. John R. Colson, Chairman of the Board and Chief Executive Officer, and John R. Wilson, Director, President of the Electric Power Division during 2010, and currently an advisor since January 1, 2011 to PAR Electrical Contractors, Inc., one of Quanta’s subsidiaries, are employees of Quanta and thus receive no compensation for their services as directors of Quanta. The compensation received by Messrs. Colson and Wilson as employees of Quanta is set forth in the 2010 Summary Compensation Table on page 38.

Pursuant to our director compensation policy, each non-employee director currently receives a fee for attendance at each meeting of the Board or any committee according to the following schedule: $2,000 for attendance at a board meeting in person; $1,000 for attendance at a board meeting by telephone; $1,000 for attendance at a committee meeting in person; and $500 for attendance at a committee meeting by telephone.

Upon initial election to the Board at an annual meeting of stockholders, each such initially elected non-employee director receives an annual cash retainer payment of $50,000 and an annual award of shares of restricted stock having a value of $150,000. Upon initial appointment to the Board other than at an annual meeting of stockholders, for the period from the appointment through the end of the director service year during which the appointment is made, each such initially appointed non-employee director receives a pro rata portion of both (i) an annual cash retainer payment of $50,000 and (ii) an annual award of shares of restricted stock having a value of $150,000. At every annual meeting of stockholders at which a non-employee director is re-elected or remains a director, each such re-elected or remaining non-employee director receives an annual cash retainer payment of $50,000 and an annual award of shares of restricted stock having a value of $100,000.

In addition, at every annual meeting of the Board, the chairman of the Audit Committee receives an annual cash retainer payment of $14,000, the chairman of the Compensation Committee receives an annual cash retainer payment of $10,000 and the chairman of the Governance and Nominating Committee receives an annual cash retainer payment of $7,500.

Unless the director’s service is interrupted, shares of restricted stock awarded to non-employee directors vest over three years in three equal annual installments. Any unvested shares of restricted stock will vest in full if the non-employee director is not nominated for or elected to a new term or resigns at our convenience. If the non-employee director voluntarily resigns or is asked to resign, or is removed for cause prior to vesting, all unvested shares of restricted stock will be forfeited. Directors are reimbursed for reasonable out-of-pocket expenses incurred in attending meetings of the Board or the committees thereof, and for other expenses reasonably incurred in their capacity as directors of Quanta. Currently, nine non-employee director nominees are standing for election at this meeting.

EXECUTIVE COMPENSATION AND OTHER MATTERS

Compensation Discussion and Analysis

Executive Summary

This Compensation Discussion and Analysis (“CD&A”) describes Quanta’s executive compensation program for 2010. We use this program to attract, motivate and retain the employees who lead our business. In particular, this CD&A explains how the Compensation Committee made its compensation decisions for our named executive officers, or NEOs, for 2010 and describes how this compensation fits within the Compensation Committee’s guiding principles with respect to NEO compensation. The NEOs are our Chairman and Chief Executive Officer, John R. Colson; our Chief Financial Officer, James H. Haddox; and our three other most highly compensated executive officers during 2010: James F. O’Neil III, President and Chief Operating Officer; John R. Wilson, President — Electric Power Division through December 31, 2010; and Kenneth W. Trawick, President — Telecommunications and Renewables Division.

Quanta’s NEO compensation is primarily comprised of base salary, annual short-term incentives and long-term incentives. Our compensation philosophy links executive compensation to both individual and company performance, with approximately two-thirds of total target NEO compensation each year being “at-risk” and, therefore, dependent upon performance against individual and company incentive targets.

Compensation awards in 2010 reflected the Compensation Committee’s ongoing commitment to a pay-for-performance philosophy. The individual and company short-term and long-term performance goals, which were established during challenging economic times, were partially met in 2010, resulting in below-target awards to each NEO. Despite overall performance below target in 2010, equity nevertheless represents a substantial portion of each NEO’s compensation as a percentage of total compensation (base, short-term incentive and long-term equity). Specifically:

• Approximately 76% of total target compensation in 2010 for the CEO was “at risk” performance-based compensation pursuant to the incentive compensation plans described below, and of the total direct compensation of the CEO for fiscal 2010, approximately 42% was in equity, 37% was in base salary and 21% in short-term incentive; and

• Approximately 66% of total target compensation in 2010 for the NEOs (other than the CEO) was “at risk” performance-based compensation, and of the total direct compensation of the NEOs (other than the CEO) for fiscal 2010, on average, approximately 20% was in equity, 49% was in base salary and 31% in short-term incentive.

Equity-based awards will continue to play an important role in this challenging economic environment because they provide incentives for the creation of stockholder value and promote an ownership culture. As Quanta moves forward into 2011, the Compensation Committee is aware of the difficult business environment, the continuing uncertainty in the marketplace, and the resulting challenges with respect to executive compensation. The Compensation Committee will continue to monitor trends and developments to ensure that Quanta provides the appropriate executive compensation incentives and remains competitively positioned for executive talent, while not encouraging excessive risk-taking by management.

Compensation Committee

Overview

The Compensation Committee administers the compensation programs for all of our NEOs. As described above under “Corporate Governance — Compensation Committee,” the Board has determined that each member of the Compensation Committee is “independent” within the meaning of the NYSE corporate governance listing standards and our Corporate Governance Guidelines. The Compensation Committee’s guiding principles with respect to NEO compensation are:

• to align our NEOs’ incentives with stockholder value creation;

• to attract, motivate and retain the best possible executive officer talent by maintaining compensation programs that allow us to effectively compete with our competitors;

• to tie cash and stock incentives to the achievement of measurable company, business unit and individual performance goals that are linked to our long-term strategic plans; and

• to promote an ownership culture.

Consistent with these principles, the Compensation Committee has implemented and maintained compensation plans that reward our NEOs for their contributions to Quanta’s short-term and long-term performance and for creating and building stockholder value.

In the first quarter of each fiscal year, the Compensation Committee meets to discuss our prior year’s financial performance, to evaluate the performance of our NEOs and to determine the amounts, if any, that will be awarded to each NEO under our annual, supplemental and discretionary incentive plans (each of which is described below) for the prior fiscal year. In addition, the Compensation Committee establishes the upcoming fiscal year’s financial performance goals and strategic goals that will be used in evaluating the performance of each NEO under our incentive plans and establishes compensation targets for each NEO for the upcoming fiscal year. The Compensation Committee seeks to maintain the competitiveness of our executive compensation levels with those of our peers and competitors and considers various factors in determining overall compensation and the individual components of compensation of each NEO, including (i) the results of compensation benchmarking studies and published compensation survey data, (ii) economic and market conditions, (iii) the effects of inflation, (iv) changes in our business operations, (v) changes in the compensation practices of our competitors, (vi) the executive officer’s position, experience, length of service and performance, (vii) company performance and (viii) the judgment of each member of the Compensation Committee based upon prior experiences with executive compensation matters. The influence of these factors on NEO compensation is discussed further below.

Use of Compensation Benchmarking Studies and Published Compensation Survey Data

One of the Compensation Committee’s guiding principles is to attract, motivate and retain the best possible executive officer talent, which is important to the success of our business. Consistent with this guiding principle, the Compensation Committee desires to create total compensation opportunities competitive with the median compensation levels of our peer companies (as identified below) by generally establishing total target compensation, consisting of base salary, annual incentives and long-term incentives, for our NEOs within +/-15% of the median of our peer group. To determine competitive market pay levels, the Compensation Committee utilizes a compensation benchmarking study and published compensation survey data for our industry that are prepared and compiled for the committee by outside consultants. This data assists the Compensation Committee in establishing the overall compensation levels for our NEOs, determining the significance of individual

23

components of compensation, and determining how to allocate compensation between short-term and long-term (or cash and non-cash) compensation. Typically, the Compensation Committee engages outside consultants on an annual basis to conduct a compensation benchmarking study for our NEOs.

Although the compensation benchmarking studies play an important role in establishing competitive compensation practices, the Compensation Committee uses such studies only as a point of reference and not as a determinative factor for our NEOs’ compensation. The compensation benchmarking studies do not supplant the significance of individual and company performance that the Compensation Committee considers when making compensation decisions. Because the information provided by compensation benchmarking studies is just one piece of information utilized in setting executive compensation, the Compensation Committee uses its discretion in determining the nature and extent of its use.

The Compensation Committee Charter grants to the Compensation Committee the authority to retain advisors and compensation consultants and to approve their compensation. These advisors report directly to the Compensation Committee.

In 2010, the Compensation Committee independently retained Ernst & Young LLP (“E&Y”) to perform a compensation benchmarking study (the “2010 E&Y Compensation Benchmarking Study”) that provides market data on base salary, total cash compensation (base salary plus annual incentive compensation) and total direct compensation (total cash compensation plus long-term incentive compensation) for each applicable NEO position. E&Y did not provide, and was not asked by the Compensation Committee to provide, recommendations as to specific compensation payments to our NEOs. The Compensation Committee instructed E&Y to report directly to the Committee, but authorized E&Y to communicate with Darren B. Miller, our Vice President of Information Technology and Administration, to obtain information. E&Y, with input from our management, assembled a group of companies for the purpose of obtaining competitive data and, with Compensation Committee approval, selected the following eleven companies for inclusion in the 2010 E&Y Compensation Benchmarking Study. These companies were chosen because they were either a direct competitor or provided similar services and/or had a similar market capitalization:

• Chicago Bridge & Iron Company N.V.

• Comfort Systems USA, Inc.

• Dycom Industries, Inc.

• Emcor Group, Inc.

• Fluor Corporation

• Jacobs Engineering Group Inc.

• MasTec, Inc.

• MYR Group Inc.

• Pike Electric Corporation

• The Shaw Group Inc.

• URS Corporation

As a result of mergers, acquisitions, new public companies and other changes, the Compensation Committee will periodically update the companies in our future compensation benchmarking studies using the criteria outlined above.

24

The 2010 E&Y Compensation Benchmarking Study provided information regarding compensation programs of, and the average and median compensation levels among, the eleven companies listed above in the peer group. E&Y also utilized several sources of published compensation survey data by matching, to the extent possible, with management’s input, the titles and job descriptions of our NEOs with those in the surveys to provide us with additional competitive compensation information.

In 2011, the Compensation Committee retained E&Y to perform another compensation benchmarking study to provide similar data for 2011 (the “2011 E&Y Compensation Benchmarking Study”). The Compensation Committee utilized the 2011 E&Y Compensation Benchmarking Study as a point of reference in establishing compensation targets for the 2011 performance year for our NEOs (in the aggregate as well as for each component of our compensation plans, including base salary.) The Compensation Committee has also engaged E&Y from time to time in the past to assist it in reviewing the structure of our compensation plans.

Our Governance and Nominating Committee separately engaged E&Y in 2010 to perform a director compensation benchmarking study that provided market data for each element of board compensation, including cash retainers, meeting fees, committee fees and equity compensation. Additionally, management has engaged E&Y from time to time in the past to provide compensation benchmarking services with respect to executive and non-executive officer and management positions. Additional discussion regarding the services provided by E&Y during 2010 is set forth in Fees of the Compensation Committee Consultant below.

Management’s Role in the Compensation-Setting Process

Our Chief Executive Officer plays an important role in setting the compensation of our NEOs. After taking into account input from other members of management, our Chief Executive Officer evaluates NEO performance and makes recommendations to the Compensation Committee relating to the following: (i) compensation plans, (ii) financial performance goals and strategic goals for each NEO, (iii) NEO compensation targets (other than with respect to himself), and (iv) base salary levels and cash incentives and equity awards (other than with respect to himself). Although our Chief Executive Officer makes recommendations to the Compensation Committee, the Compensation Committee has final authority and complete discretion in ultimately determining and setting NEO compensation plans, goals, targets, salary and awards.

In the first quarter of each fiscal year, our Chief Executive Officer and certain other executive officers meet with the Compensation Committee to propose Quanta’s financial performance goals for the current fiscal year. The Compensation Committee reviews these goals and adjusts them as it deems appropriate. Each of our NEOs proposes his individual strategic goals for the upcoming fiscal year to our Chief Executive Officer. Our Chief Executive Officer reviews and modifies the submitted strategic goals, as he deems appropriate, and, together with his own individual strategic goals, submits them to the Compensation Committee for its consideration. Once the Compensation Committee has reviewed, modified, as necessary, and approved each NEO’s strategic goals, the Compensation Committee uses such goals, along with the financial performance goals, to determine potential payouts under our executive compensation plans. In addition, our Chief Executive Officer selects, subject to approval by the Compensation Committee, the participants in our annual and supplemental incentive plans for each fiscal year and the individuals to receive an award under our discretionary plan in any fiscal year. The financial performance goals and strategic goals approved by the Compensation Committee for the 2010 performance year are discussed below in Elements of Executive Compensation and Executive Compensation Decisions for the 2010 Performance Year, respectively.

At the request of the Compensation Committee, our Chief Executive Officer and certain other executive officers also participate in the Compensation Committee’s review of Quanta’s and each NEO’s performance in the prior fiscal year for purposes of determining appropriate NEO compensation awards. Our Chief Executive Officer presents to the Compensation Committee his evaluation of the performance of the other NEOs, taking into account each of their strategic goals, and his compensation recommendations as to each of them. The Compensation Committee considers these evaluations in determining salaries for the upcoming fiscal year and the awards to be made, if any, pursuant to our incentive plans for the prior fiscal year.

25

To assist the Compensation Committee as it makes its compensation decisions, management also provides detailed spreadsheets for the NEOs indicating, among other things:

• the salary and compensation payouts, both cash and equity, approved by the Compensation Committee for the NEOs under our incentive plans for the two years immediately preceding the year under consideration;

• financial performance goals and individual strategic goals for the NEOs for the prior fiscal year;

• the Chief Executive Officer’s recommendations as to salary for the current fiscal year, as well as to the compensation payouts (other than as to himself), both cash and equity, for the prior fiscal year under our incentive plans; and

• the amounts of compensation that would be payable in the upcoming year to each of our NEOs under target payouts under our incentive plans.

These spreadsheets bring together, in one place, several elements of actual and targeted compensation of our NEOs, so that the Compensation Committee may analyze both the individual elements of compensation (including the compensation mix) and the total amount of actual and targeted compensation for each NEO for a particular performance year in connection with the Committee’s consideration of the factors influencing the various elements of NEO compensation.

None of our NEOs are present during the Compensation Committee meetings when the Compensation Committee is discussing such NEO’s individual performance relative to his respective goals and awards.

2010 Compensation Committee Meetings

The Compensation Committee met a total of five times during the fiscal year ended December 31, 2010. The significant actions taken by the Compensation Committee with respect to executive compensation matters in 2010 include: (i) approving the payouts under our incentive plans relating to the 2009 performance year; (ii) approving the financial performance and individual strategic goals and related compensation targets for the 2010 performance year; (iii) retaining E&Y to conduct the 2010 E&Y Compensation Benchmarking Study; (iv) adopting our annual, supplemental and discretionary incentive plans for the 2010 performance year; and (v) approving and recommending that stockholders approve the proposed 2011 Omnibus Equity Incentive Plan.

How Our Compensation Programs Work

The Compensation Committee has designed our compensation programs to reward strong performance by both Quanta and the individual NEOs by directly linking a significant portion of our NEOs’ pay to performance. The Compensation Committee believes that the two financial performance goals critical in measuring our success and stockholder value creation are Quanta’s operating income and return on equity (“ROE”) (as both terms are defined in the annual incentive plan and supplemental incentive plan, respectively, and as discussed in further detail below in “Elements of Executive Compensation — Annual Incentive Plan” and “Elements of Executive Compensation — Supplemental Incentive Plan,” respectively). Operating income is the primary driver of net income, which is a key element impacting our stock price. In comparison to net income, however, operating income is a more direct measure of the effectiveness of our business operations. ROE measures our effectiveness in generating financial return relative to our stockholders’ equity. The Compensation Committee ties a substantial portion of the compensation provided to our NEOs to their contributions in achieving success with respect to these two financial performance goals. When determining the operating income and ROE financial performance goals, the Compensation Committee uses a multiplier to incorporate a “stretch” factor (as further discussed below) that it believes will challenge our NEOs to excel in the performance of their duties.

26

In addition to rewarding our NEOs for the achievement of financial performance goals, the Compensation Committee rewards them for their achievement of certain individual strategic goals that it believes are critical to stockholder value creation. The Compensation Committee establishes these goals for each NEO, with input from the CEO and the individual NEOs, as discussed above under “Compensation Committee — Management’s Role in the Compensation-Setting Process.” The 2010 strategic goals for each of our NEOs are identified in “Executive Compensation Decisions for the 2010 Performance Year” below.

Although the Compensation Committee makes many decisions in the first quarter of the fiscal year, the Compensation Committee remains engaged throughout the year in evaluating our performance and the performance of our NEOs and making equitable adjustments to financial performance goals as it deems appropriate to account for events that occur that significantly impact the ability, positively or negatively, of Quanta to achieve the originally established financial performance goals. The Compensation Committee measures the effectiveness of our compensation programs based on the programs’ success in creating incentives for our NEOs to meet and exceed the financial performance and strategic goals established by the Compensation Committee. In 2010, the Compensation Committee adjusted the operating income performance goal for the 2010 performance year (as discussed below) primarily to account for Quanta’s acquisition of Valard Construction LP and certain of its affiliates (“Valard”) in October 2010.

Under our supplemental incentive plan (described below), assuming the applicable plan goals are achieved, the Compensation Committee typically rewards our NEOs with restricted stock, which generally vests over three years in equal annual installments. The Compensation Committee believes that such restricted stock awards encourage the alignment of the NEOs’ interests with those of our stockholders. Moreover, the vesting period of the restricted stock encourages an ownership culture, executive officer retention and the preservation of stockholder value. All grants of restricted stock to our NEOs in 2010 were made pursuant to the Quanta Services, Inc. 2007 Stock Incentive Plan.

Elements of Executive Compensation

The key components of our current compensation program for our NEOs are (i) base salary, (ii) awards under our annual, supplemental and discretionary incentive plans and (iii) other compensation consisting primarily of matching 401(k) contributions and certain perquisites. Each component of our compensation program has a critical role in creating compensation payouts that motivate and reward strong performance and retaining the NEOs who deliver such performance. The Compensation Committee considers each compensation component individually and all compensation components in the aggregate when making decisions regarding amounts that may be awarded under each other compensation component.

Base Salary

Base salary is a critical element of our NEO compensation because it provides NEOs with a base level of monthly income that is consistent with competitive practices. Base salaries for NEOs, including our Chief Executive Officer, are determined annually by the Compensation Committee, taking into account such factors as competitive industry salaries (especially the salary practices of companies in our peer group), a subjective assessment of the nature of the position, and the contribution, experience, level of responsibility and length of service of the NEO. While base salaries provide a basic level of economic security for our NEOs, a significant portion (generally greater than 65%) of an NEO’s total target compensation is performance-based compensation pursuant to the incentive compensation plans described below.

Annual Incentive Plan

Our annual incentive plan is designed to provide our NEOs with performance awards payable annually in cash in recognition of Quanta achieving a specified financial performance goal that is approved by the Compensation Committee (as discussed below). The Compensation Committee decided to pay such performance awards in cash rather than in equity largely to keep our compensation program competitive with those of our direct competitors, which are predominantly private companies that pay all compensation in cash.

27

In recent years, including the 2010 performance year, each NEO’s award pursuant to the plan was determined based on the achievement by Quanta of a certain operating income goal, which the Compensation Committee believes encourages our NEOs to increase stockholder value by focusing on growth in revenue and earnings. Taking into account competitive market data, the Compensation Committee establishes the operating income financial performance goal by applying a multiplier (which in 2010 was 110%) to the operating income amount budgeted for the year as approved by the Board so that our NEOs will be challenged to excel in the performance of their duties. For purposes of the annual incentive plan, operating income is defined as operating income, excluding goodwill amortization, gain (loss) on sale of assets and non-cash compensation, less interest expense, net of interest income. For the 2010 performance year, the Compensation Committee initially established the operating income financial performance goal at $382,699,000 and subsequently decreased it to $378,709,000, primarily to account for the impact of the Valard acquisition on budgeted operating income, as the Valard acquisition was completed late in the year, and the contribution of Valard’s results following the acquisition was more than offset by the transaction costs associated with the acquisition.

The payout for each NEO under the annual incentive plan relates to a percentage of such NEO’s salary (the “AIP Target Incentive”). The Compensation Committee, after taking into account, among other things, the results of the 2010 E&Y Compensation Benchmarking Study and published compensation survey data as well as the individual NEO’s position, experience and level of responsibility, established the AIP Target Incentives for the 2010 performance year for Messrs. Colson and O’Neil as 100% of their respective base salaries and for Messrs. Haddox, Trawick and Wilson as 90% of their respective base salaries. The Compensation Committee believes providing Messrs. Colson and O’Neil with a higher AIP Target Incentive is appropriate considering that the job responsibilities of Messrs. Colson and O’Neil consist of managing the entire Quanta organization as opposed to the more specific job responsibilities of Messrs. Haddox, Wilson and Trawick. In 2010, NEOs could earn cash awards under the annual incentive plan as follows (when the attainment of the performance goal falls between the designated percentages in the below table, the cash awards are determined by interpolation):

Percentage of Operating Income Goal Attained	Payout as a Percentage of AIP Target Incentive
Less than 75%	0%
75%	25%
80%	40%
85%	55%
90%	70%
95%	85%
100%	100%
150%	150%
200% or greater	200%

Quanta met or exceeded its financial performance goal under the annual incentive plan for three of the past five performance years. For the 2010 performance year, Quanta achieved operating income as calculated pursuant to our annual incentive plan of approximately $321,778,000, which represented approximately 85% of its operating income goal under the annual incentive plan and equated to a payout of 55% of the AIP Target Incentive.

Supplemental Incentive Plan

Our supplemental incentive plan provides additional awards to our NEOs based upon Quanta’s performance against a specified financial performance goal and the NEOs’ individual performance against specified strategic goals. The first component, which accounts for 50% of the total supplemental incentive plan payout opportunity, has been based on Quanta’s achievement of a ROE financial performance goal (the “ROE Component”), while the second component, which accounts for the remaining 50% of the payout opportunity, has been based on the NEO’s achievement of certain approved individual strategic goals (the “Strategic Goal Component”). The

28

Compensation Committee believes that the payout opportunity of the Strategic Goal Component allows the Compensation Committee to reward strong individual performance independent of whether Quanta has achieved its financial performance goals for a fiscal year.

The payouts under both components of the supplemental incentive plan are dependent on a fixed dollar amount that the Compensation Committee determines to be subject to the plan (the “SIP Target Incentive”). The Compensation Committee considered, among other things, the results of the 2010 E&Y Compensation Benchmarking Study and published compensation survey data as well as the individual NEO’s position, experience, level of responsibility and length of service, in establishing the SIP Target Incentive for the 2010 performance year. Specifically, for the 2010 performance year, the Compensation Committee established the SIP Target Incentive for each of our NEOs as follows: Mr. Colson, $1,800,000; Mr. Haddox, $500,000; Mr. O’Neil, $500,000; Mr. Trawick, $450,000; and Mr. Wilson, $450,000.

For purposes of the ROE Component, the ROE financial performance goal is broadly defined as the quotient of the budgeted amount of net income excluding amortization of intangibles, as approved by our Board and as adjusted by a multiplier to incorporate a stretch factor, over average tangible stockholder’s equity, as adjusted for certain items. The multiplier (which in 2010 was 110% and was applied to the budgeted amount approved by the Board) is used to challenge our NEOs in the performance of their duties. For the 2010 performance year, the Compensation Committee established the ROE financial performance goal at 13.5%. In 2010, NEOs could earn awards under the ROE Component up to the following amounts (when the attainment of the performance goal falls between the designated percentages in the below table, the awards are determined by interpolation):

Percentage of ROE Component Attained	Payout as a Percentage of SIP Target Incentive (ROE Component)
Less than 75%	0%
75%	25%
80%	40%
85%	55%
90%	70%
95%	85%
100%	100%
150%	150%
200% or greater	200%

Quanta met or exceeded its financial performance goal under the supplemental incentive plan for two of the past five performance years. For the 2010 performance year, Quanta achieved ROE of 10.6%, which represented approximately 79% of its ROE goal under our supplemental incentive plan and equated to a payout of 37% of the ROE Component of the SIP Target Incentive.

The Strategic Goal Component of the supplemental incentive plan is based on achieving certain individual strategic goals that are approved annually by the Compensation Committee for each NEO as described above under “Compensation Committee — Management’s Role in the Compensation-Setting Process.” The strategic goals generally relate to both quantitative and qualitative measures of performance that the Compensation Committee believes create stockholder value. A general description of the strategic goals for 2010 utilized by the Compensation Committee to evaluate the individual performances of our NEOs is set forth under “Executive Compensation Decisions for the 2010 Performance Year.” In determining payouts under this portion of our supplemental incentive plan, the Compensation Committee also considers each NEO’s demonstration of ethical behavior and compliance with our Code of Ethics and Business Conduct.

Awards under the supplemental incentive plan can be paid in cash, restricted stock or a combination thereof at the Compensation Committee’s discretion. In recent years, including the 2010 performance year, all awards have been paid in restricted stock, which vests over three years in equal annual installments, providing a concrete link between our NEOs’ compensation and the creation of stockholder value and encouraging executive officer

retention. To adjust the restricted stock awards to their cash equivalent, the Compensation Committee applies a multiplier to the dollar value of each restricted stock award paid under the supplemental incentive plan. This multiplier ensures that the value of the restricted stock awards incorporate the risk and liquidity premiums that a cash award has relative to a restricted stock award of the same dollar value. For the 2010 performance year, the Compensation Committee established the multiplier at 110%.

Discretionary Incentive Plan

Awards under the discretionary incentive plan are made at the discretion of our Chief Executive Officer, with the approval of the Compensation Committee, and are payable in cash, restricted stock or a combination thereof. These rewards provide the Chief Executive Officer and the Compensation Committee with the flexibility to, among other things, reward exceptional performance. For the 2010 performance year, the Compensation Committee approved an award under the discretionary incentive plan to Mr. O’Neil as discussed below.

Other Compensation

We have provided our NEOs with certain perquisites, including an annual executive physical program, an executive financial counseling program and personal use of our partially-owned company aircraft. We believe these perquisites assist executives in dealing with the demands of their positions. Under our corporate aircraft usage policy, our Chief Executive Officer may use our partially-owned company aircraft for personal purposes. Any personal use of our partially-owned company aircraft by any other NEO must be preapproved by our Chief Executive Officer. The limited personal use of partially-owned aircraft by our NEOs in 2010 did not result in any incremental cost to Quanta. The Compensation Committee reviews our policies with respect to perquisites on a regular basis to consider whether the perquisites should be maintained and whether, and to what extent, it may be appropriate to discontinue particular perquisites.

Our NEOs also receive matching contributions from Quanta to their 401(k) accounts, consistent with all other employees participating in Quanta’s 401(k) plan. Quanta matches 100% of an NEO’s pre-tax contributions up to the first 3% of such NEO’s base salary. Thereafter, Quanta matches 50% of an NEO’s pre-tax contributions up to the next 3% of such NEO’s base salary. All matching contributions are subject to certain limits as determined by law.

Exercise of Discretion in Executive Compensation Decisions

The Compensation Committee has complete discretion to withhold payment pursuant to any of our incentive compensation plans irrespective of whether we or our NEOs have successfully met the goals set under these plans. The Compensation Committee did not elect to withhold payment of any amounts under our incentive compensation plans with respect to the NEOs during 2010.

Grants of Equity Awards Practices

The Compensation Committee meets in the first quarter of each fiscal year to, among other things, grant equity awards, including, as discussed above, equity awards to our NEOs. This meeting occurs after our earnings release for the fourth quarter of the prior fiscal year to allow the Compensation Committee to have complete financial results for the prior fiscal year at the time that it evaluates our performance and that of our NEOs. The Compensation Committee may, in its discretion, also grant restricted stock awards throughout the year in connection with the hiring of a new executive officer or the promotion of an employee to an executive officer position. Our practice with respect to restricted stock awards is to use the closing market price on the date of grant to determine the value of the award. It is not the intention of the Compensation Committee to time the granting of any awards under our incentive plans, including those made to newly hired or newly promoted executive officers, with the release of any material, non-public information.

Executive Compensation Decisions for the 2010 Performance Year

Base Salary

The following table reflects the increases in base salaries approved by the Compensation Committee during 2010:

Named Executive Officer	Base Salary as of April 1, 2009		Base Salary as of April 1, 2010		Percentage Increase
Mr. Colson	$	832,000	$	848,640		2	%
Mr. Haddox	$	499,200	$	509,184		2	%
Mr. O’Neil	$	416,000	$	436,800		5	%
Mr. Trawick	$	457,600	$	466,752		2	%
Mr. Wilson	$	499,200	$	509,184		2	%

Based on the results of the 2010 E&Y Compensation Benchmarking Study, published compensation survey data, the annual wage increase under Quanta’s collective bargaining agreement with the International Brotherhood of Electrical Workers and certain other applicable unions, recent inflation data and the 2% base salary raise generally approved for Quanta’s other corporate employees, the Compensation Committee decided to approve a 2% increase in annual base salary for each NEO, other than Mr. O’Neil. The Committee approved a 5% increase in annual base salary for Mr. O’Neil, concluding that a higher percentage increase than the other named executive officers was warranted, based in part upon strong performance in light of individual performance objectives and also to better align his base salary with those of executives with similar positions and responsibilities at comparable companies.

Annual Incentive Plan

After an evaluation of Quanta’s achievement of the operating income financial performance goal during the 2010 performance year, the Compensation Committee awarded the following cash incentives to the NEOs under the annual incentive plan:

Named Executive Officer	Base Salary		AIP Target Incentive			Percent Payout of AIP Performance Goal			Incentive Award Earned
Mr. Colson	$	848,640		100	%		55	%	$	466,752
Mr. Haddox	$	509,184		90	%		55	%	$	252,046
Mr. O’Neil	$	436,800		100	%		55	%	$	240,240
Mr. Trawick	$	466,752		90	%		55	%	$	231,042
Mr. Wilson	$	509,184		90	%		55	%	$	252,046

31

Supplemental Incentive Plan

The Compensation Committee also approved awards under the supplemental incentive plan for Quanta’s level of achievement of the ROE financial performance goal and the level of achievement by each of the NEOs of their individual strategic goals:

ROE Component

Named Executive Officer	SIP Target Incentive (ROE Component)		Percent Payout of SIP Performance Goal (ROE Component)			Incentive Award  Earned(a)
Mr. Colson	$	900,000		37	%	$	333,000
Mr. Haddox	$	250,000		37	%	$	92,500
Mr. O’Neil	$	250,000		37	%	$	92,500
Mr. Trawick	$	225,000		37	%	$	83,250
Mr. Wilson	$	225,000		37	%	$	83,250

(a) As indicated in Elements of Executive Compensation – Supplemental Incentive Plan Awards above, the supplemental incentive plan applies a multiplier to the dollar value of restricted stock awards issued in lieu of cash awards thereunder to adjust restricted stock awards to their cash equivalent. The supplemental incentive plan awards to Messrs. Colson, Haddox, O’Neil and Trawick for the 2010 performance year were paid in restricted stock, and Quanta issued shares of restricted stock in satisfaction of these supplemental incentive awards with an aggregate grant date fair value of 110% of the incentive award earned. The supplemental incentive plan award to Mr. Wilson for the 2010 performance year was paid in cash and, therefore, no multiplier was applied.

(a) As indicated in Elements of Executive Compensation — Supplemental Incentive Plan Awards above, the supplemental incentive plan applies a multiplier to the dollar value of restricted stock awards issued in lieu of cash awards thereunder to adjust restricted stock awards to their cash equivalent. The supplemental incentive plan awards to Messrs. Colson, Haddox, O’Neil and Trawick for the 2010 performance year were paid in restricted stock, and Quanta issued shares of restricted stock in satisfaction of these supplemental incentive awards with an aggregate grant date fair value of 110% of the incentive award earned. The supplemental incentive plan award to Mr. Wilson for the 2010 performance year was paid in cash and, therefore, no multiplier was applied.

Discretionary Incentive Plan

The Compensation Committee believed it was appropriate to recognize Mr. O’Neil with an award under the discretionary incentive plan to recognize his overall leadership and remarkable development in a relatively new position as President and Chief Operating Officer. The Committee acknowledged Mr. O’Neil’s especially challenging individual strategic goals for 2010 and was pleased with his efforts toward reaching very difficult objectives. For the 2010 performance year, the Compensation Committee approved a $100,000 award of restricted stock to Mr. O’Neil under the discretionary incentive plan.

34

Conclusion

As indicated above, the Compensation Committee generally targets total direct compensation for each NEO within +/-15% of the median of our peer group. For 2010, the total direct compensation of Messrs. Colson, O’Neil, Haddox, Trawick and Wilson was approximately 46%, 42%, 31%, 34% and 27%, respectively, below the median target direct total compensation of our peer group. The Compensation Committee believes that the actual total direct compensation for 2010 for these NEOs is appropriate considering that Quanta did not fully achieve its financial performance goals and the individuals did not fully achieve their individual strategic goals for the 2010 performance year.

Stock Ownership Guidelines

We expect all of our directors and executive officers to display confidence in us by ownership, after five years of service as a director or executive officer, of a significant amount of our stock. Our Governance and Nominating Committee has established minimum stock ownership guidelines, for which the amounts are calculated as follows:

• for directors, the director’s annual cash retainer (excluding the annual cash retainer paid to the chairman of each committee of the Board) is multiplied by four (4) times; and

• for our executive officers, including our NEOs, the executive officer’s base salary is multiplied by the appropriate multiple as follows:

• Chief Executive Officer — 5x

• Chief Financial Officer — 4x

• Chief Operating Officer — 4x

• Operating Division President — 3x

• Other Executive Officer — 1x

The amount of each of the above is then divided by the average closing price of our Common Stock during the immediately preceding 12 months as reported by the NYSE to calculate the number of shares required to be held by each director or executive officer. Under the stock ownership guidelines, the amount of unvested restricted stock held by a director or executive officer is included in the calculation of the amount of such director’s or executive officer’s ownership. The number of shares required to be held by any individual will only change, with respect to directors, annually as of our annual Board meeting and, with respect to an executive officer, if the individual is promoted to a higher position.

As of December 31, 2010, all of our directors and NEOs were in compliance with our stock ownership guidelines.

Changes to 2011 Compensation Program

As in prior years, our Compensation Committee undertook a comprehensive review of our executive compensation program in 2010 with the goal of identifying and implementing any appropriate changes to ensure that our incentive compensation remains consistent with the company’s guiding principles on executive compensation. In conducting its review, the Compensation Committee considered input from E&Y and senior management. As part of this review, E&Y prepared an analysis highlighting the pro forma impact of certain adjustments to (i) the multiplier applied to performance targets under the annual incentive plan (discussed above in “Elements of Executive Compensation – Annual Incentive Plan”) and (ii) the performance/payout scale under

35

this plan for bonuses paid (or estimated to be paid) for the 2008-2010 performance years. In addition, E&Y performed a compensation benchmarking study that provided the committee with a comparison of the performance/payout scales among members of Quanta’s peer group and certain of Quanta’s customers, detailing performance at which incentive payouts begin (specifically, percentage of targeted financial performance goal required to be achieved) and the corresponding payout at such minimum required performance (specifically, percentage of targeted incentive payout), as well as the maximum potential incentive payout (specifically, percentage of targeted incentive payout) and the performance required to achieve such payout (specifically, percentage of targeted financial performance goal required to be achieved). This analysis also included the average and median of such minimum and maximum incentive payouts and corresponding required performance among these companies.

Based on this review, the Compensation Committee decided to implement certain changes to our executive compensation program for 2011. These changes are intended to:

• align performance and payment ranges with those of our competitors;

• create incentives for building sustainable growth without inappropriate risk taking;

• establish incentive compensation targets that more appropriately reflect Quanta’s size, its performance and market conditions;

• offer a more consistent and competitive incentive program for our executive officers; and

• help attract, motivate and retain the best possible executive officer talent.

The changes include a change to the mechanism for adjusting budgeted amounts for purposes of computing financial performance targets and a change to existing performance/payout scales. As described above in “How our Compensation Programs Work,” a multiplier was historically applied to adjust budgeted operating income for purposes of computing the targeted financial performance goal for compensation purposes. Budgeted operating income, as adjusted by the multiplier, has been the targeted financial performance goal for the annual incentive plan, as well as a component of return on equity, which has been the targeted financial performance goal for the supplemental incentive plan. The historical multiplier was originally designed to challenge our NEOs in the performance of their duties. Because Quanta was much smaller in size when the multiplier was determined several years ago, the Compensation Committee believes that utilizing a multiplier is no longer the most effective way to compute appropriate and incentivizing performance targets. Consequently, the Compensation Committee has revised the method of adjusting budgeted operating income for purposes of establishing financial performance targets under the annual incentive plan and the supplemental incentive plan. Starting with the 2011 performance year, budgeted operating income will be adjusted for purposes of establishing the targeted financial performance goals by adding corporate plan participants’ targeted incentive payouts, in lieu of adjusting by the former multiplier. The Compensation Committee believes that the revised adjustment mechanism, which is designed to ensure that Quanta generates sufficient incremental income over budget to cover the bonus requirements, will incentivize management to exceed budgeted targets.

As described above in “Elements of Executive Compensation,” the annual incentive plan and supplemental incentive plan contain a sliding performance/payout scale in which incentive payouts begin at 75% of target performance and reach the maximum potential at 200% of target performance. Because Quanta has grown significantly since these payout scales were initially adopted, and because the performance targets are now also adjusted for acquisitions completed during the year, achievement of the maximum range has become virtually impossible to achieve under any circumstances, and therefore, is very unlikely to ever occur. For instance, NEO payouts under the annual incentive plan have not exceeded 130% of the targeted incentive payout in any of the last seven performance years. The Compensation Committee believes that an incentive program with a maximum payout that is unachievable does not appropriately incentivize our executive officers to excel in the performance of their duties. As such, the Compensation Committee has adjusted the payout scale under both plans so that,

36

given the appropriate level of performance, executive officers are able to reach the maximum potential payout at 150% of target performance. Although achieving maximum payout under the revised plan will continue to be very difficult, it will not be impossible. Further, as a result of this adjustment, performance between 100% and 150% of target performance will result in increased payouts as compared to the 2010 payout scale. This modification to the payout scale is supported by the data in the benchmarking study conducted by E&Y, and the Compensation Committee believes that the modification provides more realistic incentives for our executive officers, which in turn will benefit Quanta’s stockholders, and is more in alignment with the incentive compensation paid by our competitors.

Employment Agreements

We have entered into an employment agreement with each of our NEOs. Under the terms of our employment agreements, the Chief Executive Officer and the other NEOs are entitled to payments and benefits upon the occurrence of specified events including termination of employment and upon a change in control of Quanta. The specific terms of these arrangements, as well as an estimate of the compensation that would have been payable had they been triggered as of fiscal year-end, are described below in the section entitled “Potential Payouts Upon Termination or Change in Control.” In the case of each employment agreement, the terms of these arrangements were set through the course of arms-length negotiations with each of the NEOs. The termination of employment provisions of the employment agreements provide those individuals with a fixed amount of compensation upon termination as an inducement to offset the potential risk of leaving their prior employer or foregoing other opportunities in order to join or maintain employment with us, as applicable. At the time of entering into these agreements, the Compensation Committee considered our aggregate potential obligations in the context of the desirability of hiring or maintaining the employment of the individual, as applicable, and the expected compensation upon joining or maintaining employment with us, as applicable.

Under our employment agreements with our NEOs (except Mr. O’Neil), if benefits to which the applicable NEOs become entitled are subject to excise taxes under Section 4999 of the Internal Revenue Code of 1986, as amended (the Internal Revenue Code), then the NEOs generally will be entitled to an additional payment in an amount equal to the excise tax imposed plus any federal, state and local income taxes and additional excise taxes attributable to such payment. Mr. O’Neil’s employment agreement does not include this provision, as the Compensation Committee determined to no longer offer this benefit at the time Quanta entered into the employment agreement with Mr. O’Neil.

Impact of Regulatory Requirements on our Executive Compensation Decisions

The Compensation Committee considers accounting and tax implications of its compensation decisions as one factor among many. Section 162(m) of the Internal Revenue Code limits a company’s ability to deduct compensation paid in excess of $1 million during any fiscal year to each of certain executive officers unless the compensation is “performance-based” as defined under federal tax laws. To the extent possible, the Compensation Committee structures compensation and awards to preserve the federal income tax deductibility of the compensation payable to our NEOs. The Compensation Committee may choose, however, to provide compensation that may not be deductible if it believes that such payments are appropriate to ensure that our NEOs receive total compensation that is competitive with our peer group or reflects superior performance.

(1) The amounts shown for 2010 under “Stock Awards” reflect the aggregate grant date fair value for restricted stock granted during the fiscal year ended December 31, 2010, calculated in accordance with FASB ASC Topic 718. The value ultimately realized by the NEO upon the actual vesting of the award(s) may or may not be equal to this determined value. The table does not include information regarding equity-based awards related to 2010 performance that were granted in March 2011, which awards will be reflected in the 2011 Summary Compensation Table. For a discussion of these equity-based awards, please read “Compensation Discussion and Analysis — Executive Compensation Decisions for the 2010 Performance Year.” Shares of restricted stock vest over three years in equal annual installments commencing on the applicable vesting date for the quarter in which the award is made, assuming the NEO continues to meet the requirements for vesting. Dividends are paid on restricted stock as and when dividends are paid on Common Stock.

(2) Amounts shown under “Non-Equity Incentive Plan Compensation” represent the dollar value of cash incentives earned under our Annual Incentive Plan for Messrs. Colson, Haddox, O’Neil and Trawick and the dollar value of cash incentives under both the Annual Incentive Plan and the Supplemental Incentive Plan for Mr. Wilson. For further details regarding these plans, see “Compensation Discussion and Analysis — Elements of Executive Compensation — Annual Incentive Plan” and “— Supplemental Incentive Plan” above. The cash incentives reflected in the table were earned during the 2010, 2009 and 2008 performance years as indicated and were approved by the Compensation Committee and paid in March of 2011, 2010 and 2009, respectively.

(3) The amounts reflected under “All Other Compensation” for fiscal 2010 are identified in the All Other Compensation Table below.

(4) Effective December 31, 2010, Mr. Wilson retired from his position as President — Electric Power Division, but continues to serve as an employee of PAR Electrical Contractors, Inc., one of Quanta’s subsidiaries (“PAR”), primarily in an advisory capacity.

These payouts could be in the form of cash, restricted stock or a combination thereof, provided that the portion of the incentive awarded in restricted stock is multiplied by 110% to ensure that the value of the restricted award incorporates the risk and liquidity premium of a cash award relative to a restricted stock award of the same dollar value, with the resulting amount divided by the closing price of Quanta’s common stock on the date of grant date.

(3) The amounts shown reflect the aggregate grant date fair value of restricted stock granted during the fiscal year ended December 31, 2010 to the NEOs, calculated in accordance with FASB ASC Topic 718. The value ultimately realized by the NEO upon the actual vesting of the award(s) may or may not be equal to this determined value. All of such restricted stock awards vest over a three-year period (assuming continued employment), subject to the terms and conditions of the applicable restricted stock award agreements, and were earned under the 2009 Supplemental Incentive Plan.

Outstanding Equity Awards at 2010 Fiscal Year End

The following table reflects outstanding option awards classified as exercisable, unexercisable and unearned as of December 31, 2010 for each of the named executive officers. The table also reflects unvested restricted stock and unearned equity incentive plan awards held by each of the named executive officers, assuming a market value of $19.92 per share, the closing price of Quanta’s common stock on December 31, 2010.

2010 Options Exercised and Stock Vested Table

The following table reflects certain information regarding the exercise of options and the vesting of stock awards by each of our named executive officers during the 2010 fiscal year:

	Option Awards				Stock Awards
Name	Number of Shares Acquired on Exercise (#)		Value Realized on Exercise ($)		Number of Shares Acquired on Vesting(1) (#)		Value Realized on Vesting(2) ($)
John R. Colson		—		—		73,416		1,394,904
James H. Haddox		—		—		25,522		484,918
James F. O’Neil III		—		—		13,595		258,305
John R. Wilson		—		—		18,485		351,215
Kenneth W. Trawick		—		—		18,045		342,855

(1) Shares acquired on vesting include shares of restricted stock for which restrictions lapsed during fiscal 2010. All of such shares vested on February 28, 2010, and the fair market value per share our stock as of 12:01 a.m. on that date was $19.00 per share.

(2) The value realized reflects the taxable value to the named executive officer as of the date of the vesting of restricted stock. The actual value ultimately realized by the named executive officer may be more or less than the value realized as calculated in the above table, depending on whether and when the named executive officer held or sold the stock associated with the vesting occurrence.

Risk Considerations in our Compensation Program

The Compensation Committee has discussed the concept of risk as it relates to our compensation program and the Compensation Committee does not believe our compensation program encourages excessive or inappropriate risk taking for the following reasons:

• The Compensation Committee structures executive compensation to consist of both fixed and variable compensation. The fixed or base salary portion of compensation is typically set at market levels and is designed to provide a steady income regardless of Quanta’s stock price performance so that executives do not feel pressured to focus exclusively on stock price performance to the detriment of other important business metrics. The variable portions of compensation, which are described in detail above, are generally designed to reward both short- and long-term corporate and individual performance. For short-term performance, our annual incentive plan awards bonuses based on the achievement by Quanta of a certain annual operating income goal. For long-term performance, our supplemental incentive plan awards bonuses based on the achievement by Quanta of a certain annual return on equity goal as well as on the achievement by the individual plan participant of certain strategic goals. Restricted stock generally awarded under our supplemental incentive plan vests over three years in equal annual installments, which the Compensation Committee believes encourages plan participants to focus on sustained stock appreciation and promotes retention of key employees. The Compensation Committee believes that these variable elements of compensation are a sufficient percentage (generally greater than 50%) of overall compensation to motivate plan participants to produce superior short- and long-term corporate results, while the fixed element is also sufficiently high that plan participants are not encouraged to take unnecessary or excessive risks in doing so.

• The Compensation Committee also structures executive compensation at the operating unit level to consist of both fixed and variable compensation. The variable portions of compensation are generally designed to reward both short- and long-term corporate and individual performance. For short-term performance, our operating unit annual incentive plan awards bonuses based on the achievement by a particular operating unit of a certain annual operating income goal as well as the achievement of certain safety goals. For long-term performance, our operating unit supplemental incentive plan awards

42

bonuses based on the achievement by a particular operating unit of a certain annual modified return on asset goal as well as on the achievement by the individual plan participant of certain strategic goals. The Compensation Committee believes that these elements of compensation achieve objectives similar to those under our corporate incentive plans.

• As operating income, return on equity and modified return on assets are the financial performance measures for determining incentive payments under our incentive plans, the Compensation Committee believes plan participants are encouraged to take a balanced approach that focuses on corporate profitability, rather than other measures which may incentivize management to enter into projects without regard to cost structure. Further, Quanta has strict internal controls with respect to capital expenditures as well as bid and project approvals, which are designed to prevent an individual from entering into projects that do not meet certain requirements. If we are not profitable at a reasonable level, there are generally no payouts under our incentive plans (excluding the individual strategic goal and safety goal components of our incentive plans). In addition, the strategic goals approved for each plan participant are aligned with Quanta’s short- and long-term operating and strategic plans, achieve a proper risk/reward balance, and do not encourage unnecessary or excessive risk taking.

• The Compensation Committee caps awards under our annual and supplemental incentive plans, which the Compensation Committee believes also mitigates excessive risk taking. Therefore, even if Quanta or the operating unit, as applicable, and the individual dramatically exceed their respective performance goals, awards are limited. Conversely, there is a minimum level of performance under the annual and supplemental incentive plans so that awards will not be made for performance below a certain level.

• Quanta has strict internal controls over the measurement and calculation of performance goals under our incentive plans, which are designed to keep it from being susceptible to manipulation by any employee. In addition, all of our employees are required to comply with our Code of Ethics and Business Conduct, which covers, among other things, accuracy of books and records.

• The Compensation Committee believes that the combination of an operating income financial goal (through our corporate and operating unit annual incentive plans) and extended exposure to stock price performance (through our equity compensation program and stock ownership guidelines) provides an appropriate balance and discourages excessive risk taking. For example, even if plan participants could inappropriately increase Quanta’s operating income (as defined under the corporate or operating unit annual incentive plan, as applicable) by excessive expense reductions or by abandoning less profitable revenue sources, this could be detrimental to Quanta in the long term and would be discouraged under our compensation program because it would ultimately harm our stock price and the value of their equity awards. Likewise, if plan participants were to add revenue sources at low margins in an attempt to generate a higher growth company multiple and increased stock prices, it could decrease operating income and the value of their cash bonuses under the annual incentive plan.

• The Board has adopted stock ownership guidelines, which the Compensation Committee believes provide a considerable incentive for management to consider Quanta’s long-term interests because a meaningful portion of their personal investment portfolio consists of Quanta stock.

• The structure of our corporate incentive plans has not significantly changed for several years, and the Compensation Committee is not aware of any evidence that it encourages unnecessary or excessive risk taking.

Fees of the Compensation Committee Consultant

As discussed in Use of Compensation Benchmarking Studies and Published Compensation Survey Data above, the Compensation Committee independently retained E&Y in 2010 to provide advice on the amount and form of executive compensation. E&Y was also engaged to provide certain additional services to Quanta. The aggregate fees billed by E&Y for services performed during 2010 were as follows:

• $113,613 for consulting on executive compensation to the Compensation Committee, including providing executive compensation benchmarking data, reviewing Quanta’s incentive compensation plans, providing excise tax calculations for proxy statement disclosure, and participating in certain Compensation Committee meetings; and

• $65,919 for other services provided to Quanta, including (i) valuation and tax due diligence services in connection with our acquisition of Valard, and (ii) documentation and testing services related to Quanta’s compliance with Section 404 of the Sarbanes-Oxley Act of 2002.

The Compensation Committee approved the above executive compensation services and related fees. The Compensation Committee did not review or approve the other services provided by E&Y to Quanta, as the decision to engage E&Y to perform these other services was made by management in the normal course of business.

Equity Compensation Plan Information

The Quanta Services, Inc. 2007 Stock Incentive Plan (the “2007 Plan”), which was adopted by the Board and approved by our stockholders on May 24, 2007, provides for the award of restricted stock, non-qualified stock options and incentive stock options (“ISOs”). The purpose of the 2007 Plan is to provide directors, key employees, executive officers and certain advisors with additional incentives by increasing their proprietary interest in Quanta. Prior to the adoption of the 2007 Plan, awards of restricted stock and stock options were issued under the Quanta Services, Inc. 2001 Stock Incentive Plan (as amended and restated, the “2001 Plan”), which was terminated effective May 24, 2007, except that outstanding awards granted under the 2001 Plan will continue to be governed by the terms of the 2001 Plan. The aggregate number of shares of our Common Stock with respect to which options or restricted stock may be awarded under the 2007 Plan may not exceed 4,000,000 shares of our Common Stock. We have filed a Registration Statement on Form S-8 with respect to 4,000,000 shares of Common Stock issuable pursuant to the 2007 Plan.

The 2007 Plan is administered by the Compensation Committee of the Board, which, subject to applicable regulations and the terms of the 2007 Plan described below, has the sole authority to grant awards under the 2007 Plan, to construe and interpret the 2007 Plan and to make all other determinations and take any and all actions necessary or advisable for the administration of the 2007 Plan, provided that the Board, or authorized committee of the Board, may delegate to a committee of the Board designated as the Equity Grant Committee, consisting of one or more directors, the authority to grant limited awards as described below to eligible persons who are not executive officers or non-employee directors. Specifically, the Equity Grant Committee has the authority to award stock options and restricted stock, provided (i) the aggregate number of shares of Common Stock subject to stock options and/or restricted stock awarded by the Equity Grant Committee in any calendar quarter does not exceed 100,000 shares (or 20,000 shares in any calendar quarter with respect to any individual) and (ii) the aggregate value of restricted stock awarded by the Equity Grant Committee in any calendar quarter does not exceed $250,000 (or $25,000 in any calendar quarter with respect to any individual), determined in each case, based on the fair market value of the Common Stock on the date the restricted stock is awarded. In connection with the adoption of the 2007 Plan, the Board approved the designation of the Equity Grant Committee and appointed Mr. Colson as the sole member of the committee. The maximum number of shares of Common Stock subject to awards that may be granted to any individual under the 2007 Plan during any calendar year is 400,000 shares of Common Stock.

44

All of our employees (including our executive officers and directors who are also employees), non-employee directors and certain consultants and advisors are eligible to receive awards under the 2007 Plan, but only our employees (including executive officers and directors who are also employees) are eligible to receive ISOs. Awards in the form of stock options are exercisable during the period specified in each stock option agreement and generally become exercisable in installments pursuant to a vesting schedule designated by the Compensation Committee or, if applicable, the Equity Grant Committee. No option will remain exercisable later than ten years after the date of award (or five years in the case of ISOs awarded to employees owning more than 10% of our voting capital stock). The exercise price for ISOs awarded under the 2007 Plan may be no less than the fair market value of a share of Common Stock on the date of award (or 110% in the case of ISOs awarded to employees owning more than 10% of our voting capital stock). Awards in the form of restricted stock are subject to forfeiture and other restrictions until they vest. Except in certain limited circumstances and with respect to restricted stock awards awarded by the Compensation Committee covering in the aggregate no more than 200,000 shares of our Common Stock, any restricted stock award that vests on the basis of a grantee’s continuous service shall not provide for vesting which is any more rapid than annual pro rata vesting over a three year period, and any restricted stock award that vests upon the attainment of performance goals established by the Compensation Committee shall provide for a performance period of at least twelve months, in each case, as designated by the Compensation Committee or, if applicable, the Equity Grant Committee and as specified in each award agreement.

Additionally, in connection with the acquisition of InfraSource Services, Inc. (“InfraSource”) on August 30, 2007, Quanta assumed InfraSource’s 2003 Omnibus Stock Incentive Plan and 2004 Omnibus Stock Incentive Plan, in each case as amended (the “InfraSource Plans”). The InfraSource Plans were terminated in connection with the acquisition, and no further awards will be made under these plans, although the terms of these plans continue to govern outstanding awards.

The following table sets forth information as of December 31, 2010 with respect to the equity compensation plans described above, all of which have received stockholder approval.

(1) Includes 507,444 options with a weighted-average exercise price of $12.33 that were assumed in connection with Quanta’s acquisition of InfraSource on August 30, 2007.

(2) Represents the shares of Common Stock issuable as of December 31, 2010 under the 2007 Plan, which provides that the aggregate amount of Common Stock with respect to which stock options or restricted stock may be awarded may not exceed 4,000,000 shares of our Common Stock.

Potential Payments Upon Termination or Change in Control

Employment and Separation Agreements

Each NEO was party to an employment agreement (as amended, an “Employment Agreement”) during the 2010 fiscal year. Under the Employment Agreements, the applicable NEOs are eligible to receive base salary, as well as bonuses and benefits, and, at the Compensation Committee’s discretion, may be entitled to participate in any other compensation, perquisite, incentive or retirement plans, policies and arrangements that are provided

45

generally to our other executive officers. Subject to prior notice, the Employment Agreements renew automatically each year for an additional one-year term. The Employment Agreements contain customary non-competition covenants restricting the ability of the NEOs to compete with Quanta during the term of their employment and for a period of one year thereafter and prohibiting them from disclosing confidential information and trade secrets.

The Employment Agreements generally terminate upon the NEO’s (i) death, (ii) disability, (iii) termination for “good cause” (or “cause” in the case of Mr. O’Neil’s Employment Agreement) or “good reason” (as these terms are defined in the Employment Agreements and generally described below), (iv) termination without cause/good cause or good reason, or (v) termination resulting from a “Change in Control” of Quanta (as defined in each Employment Agreement and generally described below). If termination results from any of the foregoing, each applicable NEO would be entitled to all compensation earned and all benefits and reimbursements due through the date of termination, and any gross-up payments for related excise taxes (except with respect to Mr. O’Neil). Additionally, if termination results from any of the reasons set forth below, each applicable NEO would be entitled to the following severance payments:

Reason for Termination	Potential Payment(s)
Death	None
Disability	Lump-sum payment of base salary at the rate then in effect for the period remaining under the Employment Agreement or for one year, whichever is greater.
For cause / good cause by Quanta	None
Without cause / good cause by Quanta	Lump-sum payment of base salary at the rate then in effect for the period remaining under the Employment Agreement or for one year, whichever is greater (with respect to terminations of Messrs. Colson, Haddox and Wilson, payments are subject to such NEO’s execution of a waiver and release agreement).
Without cause / good cause or good reason by NEO	None

As mentioned above, each Employment Agreement may terminate upon a Change in Control of Quanta. Under the Employment Agreements of Messrs. Colson, Haddox and Wilson, a Change in Control generally occurs when (i) any person or entity acquires directly or indirectly the beneficial ownership of 50% or more of the total voting power of Quanta’s then outstanding voting securities, (ii) the majority of the Board as of the date of the NEO’s Employment Agreement are replaced other than in specific situations, or (iii) the stockholders approve a plan of complete liquidation or a sale or disposition of all or a substantial portion of Quanta’s assets. A Change in Control generally occurs under the Employment Agreements of Messrs. Trawick and O’Neil when (i) any person or entity acquires directly or indirectly the beneficial ownership of 50% or more of the total voting power of Quanta’s then outstanding voting securities, (ii) the majority of the Board as of the date of Quanta’s initial public offering (as of the date of the Employment Agreement with respect to Mr. O’Neil) are replaced other than in specific situations, (iii) the stockholders approve a merger, consolidation or reorganization of Quanta unless 50% of the total voting securities outstanding of the surviving entity are beneficially owned by at least 50% of the holders of outstanding voting securities of Quanta immediately prior to the transaction, or (iv) the stockholders approve a plan of complete liquidation or a sale or disposition of all or a substantial portion of Quanta’s assets.

Payments and benefits in connection with a Change in Control under the Employment Agreements are generally dependent on whether Quanta’s successor assumes Quanta’s obligations under such agreements. With respect to Messrs. Colson, Haddox, Trawick and Wilson, if there is no assumption of the Employment Agreement, or if there is an assumption and within 12 months of such assumption, the NEO terminates his respective Employment Agreement for good reason or is terminated other than for good cause, such NEO (i) will

46

be entitled to a lump-sum payment equal to three times the sum of (x) his annual base salary and (y) the higher of (1) the highest annual bonus paid to him under the annual incentive plan in effect on the date of the Employment Agreement for the past three fiscal years, and (2) his annual bonus paid or payable under the annual incentive plan in effect on the date of the Employment Agreement for the most recently completed or current fiscal year, (ii) will be entitled to continued benefits for him and his dependents under welfare benefit plans for three years after termination, and (iii) will not be subject to the non-competition covenants of the Employment Agreement. Mr. Haddox will also receive the above payment and benefits if during any Change in Control situation, Mr. Haddox elects to terminate his employment at least 5 days prior to the closing of the anticipated transaction giving rise to the Change in Control. With respect to Mr. O’Neil, if within 12 months following a Change in Control he terminates his Employment Agreement for good reason or is terminated other than for cause, he will be entitled to (i) a lump-sum payment equal to three times his base salary at the rate then in effect, (ii) a lump-sum payment equal to three times the highest bonus paid to him under the annual incentive plan, and (iii) continued benefits for him and his dependents under welfare benefit plans for three years after termination.

The Employment Agreements of Messrs. Colson, Haddox, Trawick and Wilson generally define good cause as the NEO’s (i) willful, material and irreparable breach of the Employment Agreement, (ii) continuing gross negligence in the performance or intentional nonperformance of his duties after notice of the same is given, (iii) willful dishonesty, fraud or material misconduct with respect to Quanta’s business, (iv) conviction of a felony or crime, or (v) chronic alcohol or illegal drug abuse. The Employment Agreement of Mr. O’Neil generally defines cause as his (i) failure or refusal to follow the reasonable directives of his supervisor that is not cured after written notice of the same is given, (ii) willful and continued failure to substantially perform his duties that is not cured after written notice of the same is given, (iii) violation of any of Quanta policies or procedures that is not cured after written notice of the same is given, (iv) engagement in conduct that is materially and demonstrably injurious to Quanta, (v) conviction of, a plea of nolo contendere, a guilty plea, or confession by him to, an act of fraud, misappropriation or embezzlement or any crime punishable as a felony or any other crime that involves moral turpitude other than under specific circumstances, (vi) use of illegal substances or habitual drunkenness, (vii) breach of the Employment Agreement that is not cured after written notice of the same is given, and (viii) repeated or continuous acts of gross neglect or gross or willful misconduct that directly relate to Quanta’s business. Good reason exists under the Employment Agreements of Messrs. Colson, Haddox, Trawick and Wilson if within twelve months following a Change in Control, such NEO is offered a “Lesser Position” (as defined in each Employment Agreement) or is required to relocate to another geographic location. Good reason exists under Mr. O’Neil’s Employment Agreement if within 12 months following a Change in Control (i) he is assigned duties inconsistent with his position, authority or responsibilities as contemplated under his Employment Agreement, or Quanta engages in any other action that results in a diminution in such position, authority or responsibilities that is not cured after written notice of the same is given, (ii) he is required to relocate to another geographic location, (iii) Quanta fails to comply with the compensation provisions of his Employment Agreement and such failure is not cured after written notice of the same is given, and (iv) Quanta fails to continue in effect any cash or stock-based incentive or bonus plan, retirement plan, welfare benefit plan or other compensation, retirement or benefit plan and policy except in certain specified circumstances.

Stock Incentive Plans

Under both the 2001 Plan and 2007 Plan (collectively, the “Plans”), generally upon a “Change in Control” (as defined in both Plans), (i) options become immediately exercisable and are released from any repurchase or forfeiture rights, and (ii) restricted stock vests and becomes free of any forfeiture restrictions. A “Change in Control” is generally defined as the occurrence of any of the following events: (i) any person becomes the beneficial owner, directly or indirectly, of securities representing 50% or more of the voting power of Quanta’s then outstanding securities, (ii) as a result of, or in connection with, any tender or exchange offer, merger or other business combination, a majority of the Board as of the date immediately preceding such transaction is replaced, (iii) Quanta is merged with another corporation, and as a result, less than 75% of the outstanding securities of the surviving corporation is owned in the aggregate by Quanta’s former stockholders, (iv) a tender or exchange offer

47

is consummated for 50% or more of the voting power of Quanta’s then outstanding securities, or (v) Quanta transfers substantially all of its assets to a corporation that is not controlled by Quanta.

Options awarded under either of the Plans may be exercised following a participant’s termination only to the extent provided in the option agreement. Generally, subject to the provisions of a particular restricted stock agreement, restricted stock awards are forfeited by a participant upon termination of such participant’s employment during the restriction period.

Estimated Potential Payments

The tables below reflect the estimated amount of payments that would be paid to each NEO in the event of such NEO’s termination. The amounts shown assume that such termination was effective as of December 31, 2010, and thus include amounts earned through such time. The actual amounts to be paid out can only be determined at the time of such NEO’s separation from Quanta. [table to be updated with 280G calculations]

(1) The welfare benefits include an approximation of the cost of continued payment of insurance premiums for up to three years after termination. The insurance premium cost is based on the actual cost of premiums for 2011 and the estimated costs of premiums for 2012 and 2013.

(2) The equity benefit represents the value of the unvested restricted stock held by the NEO as of December 31, 2010 that would accelerate upon a change in control pursuant to the Plans.

48

(3) Under Mr. Trawick’s employment agreement, he is entitled to an excise tax gross-up if an excise tax exists. Based on the calculations of his benefits upon a change in control, his parachute payments exceeded his safe harbor amount by approximately $            . This excess generated an excise tax gross-up of approximately $            . Management believes that were this fact pattern to actually occur, Mr. Trawick would be inclined to forgo $            of benefit to save Quanta the excise tax gross-up amount of approximately $            . Therefore, the above table does not reflect any potential excise tax gross-up for Mr. Trawick.

(1) The welfare benefits include an approximation of the cost of continued payment of insurance premiums for up to three years after termination. The insurance premium cost is based on the actual cost of premiums for 2011 and the estimated costs of premiums for 2012 and 2013.

(2) The equity benefit represents the value of the unvested restricted stock held by the NEO as of December 31, 2010 that would accelerate upon a change in control pursuant to the Plans.

(3) Under Mr. Trawick’s employment agreement, he is entitled to an excise tax gross-up if an excise tax exists. Based on the calculations of his benefits upon a change in control, his parachute payments exceeded his safe harbor amount by approximately $            . This excess generated an excise tax gross-up of approximately $            . Management believes that were this fact pattern to actually occur, Mr. Trawick would be inclined to forgo $             of benefit to save Quanta the excise tax gross-up amount of approximately $            . Therefore, the above table does not reflect any potential excise tax gross-up for Mr. Trawick.

CERTAIN TRANSACTIONS

North Houston Pole Line, L.P. (“North Houston”), a wholly-owned subsidiary of Quanta, is a party to certain facility leases with Properties, Etc., a general partnership of which Earl C. Austin, Jr., one of our executive officers, is a general partner. These leases have various terms through August 2014. The aggregate annual rental under these leases for 2010 was $288,064. In addition, North Houston is a party to a facility lease with Mr. Austin, which expires in August 2011, with aggregate 2010 lease payments of $99,000. Further, North Houston is a party to a facility lease with Mr. Austin’s father, which also expires in August 2011, with aggregate 2010 lease payments of $99,000. These leases relate to facilities that were occupied by North Houston when Quanta acquired North Houston in 2001. We believe that the rental rates of the above leases do not exceed fair market value.

North Houston employed Earl C. Austin, the father of Earl C. Austin, Jr., one of our executive officers, during 2010. North Houston paid Earl C. Austin an aggregate of $311,673 in salary, non-equity incentive bonus, health and welfare coverage and 401(k) plan matching contributions for 2010. In addition, during 2010, we granted to Earl C. Austin 10,455 shares of restricted stock, valued at $200,000 as of the date of grant, which vest in three equal installments beginning in March 2011. This restricted stock was granted on the same terms and conditions as restricted stock granted to other employees in 2010. North Houston’s employment of Earl C. Austin predated Quanta’s acquisition of North Houston in 2001.

Trawick Construction Company, Inc. (“Trawick Construction”), one of our wholly-owned subsidiaries, employed Doug Trawick and Matthew Trawick, the brother and son, respectively, of Kenneth W. Trawick, one of our executive officers, during 2010. Trawick Construction paid Doug Trawick an aggregate of $197,858 and Mathew Trawick an aggregate of $163,831, respectively, in salary, non-equity incentive bonus, health and welfare coverage and 401(k) plan matching contributions for 2010. In addition, during 2010, we granted to Doug Trawick 2,614 shares, valued at $50,000 as of the date of grant, and to Matthew Trawick 1,045 shares, valued at $20,000 as of the date of grant, respectively, of restricted stock, which vest in three equal installments beginning in March 2011. This restricted stock was granted on the same terms and conditions as restricted stock granted to other employees in 2010. Trawick Construction’s employment of Doug Trawick and Matthew Trawick, respectively, predated Quanta’s acquisition of Trawick Construction in 1999.

Review of Related Party Transactions

We have adopted a written policy and procedures for the review, approval and ratification of transactions with related persons. Under our policy, related persons include, among others, our executive officers and other senior level employees, directors, principal stockholders, immediate family members of such persons and any other person that could significantly influence our policies. The transactions covered under our policy generally include any business transaction between Quanta and a related person, including, among others, the sale of inventory or supplies to or the purchase of inventory or supplies from a related person, and the supply of services to or receipt of services from a related person. Related party transactions involving any of our directors, director nominees, executive officers, beneficial owners of greater than five percent of our Common Stock or Limited Vote Common Stock and any immediate family members of the foregoing require the pre-approval of the Audit Committee. In considering the approval of any related party transaction, a legitimate business case must be presented that includes the reasons that the transaction is beneficial to Quanta and does not pose an actual conflict of interest.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our directors and executive officers and persons who own more than 10% of a registered class of our equity securities to file various reports with the SEC concerning their holdings of, and transactions in, our securities. Copies of these filings must be furnished to us. Based solely on our review of the copies of those forms furnished to us and written certifications from our directors and executive officers, we believe that, during 2010, all of our directors and executive officers were in compliance with the applicable filing requirements.

REPORT FROM THE AUDIT COMMITTEE

The Audit Committee is composed of four independent directors and operates under a formal written charter adopted by the Board of Directors.

As members of the Audit Committee, our primary purpose is to assist the Board of Directors’ oversight of (1) the integrity of Quanta’s financial statements, (2) the independent registered public accounting firm’s qualifications and independence, (3) the performance of Quanta’s internal audit function and independent auditors, and (4) Quanta’s compliance with applicable legal and regulatory requirements. The Audit Committee is solely responsible for the appointment and compensation of Quanta’s independent registered public accounting firm. Management is responsible for Quanta’s financial reporting processes, including its system of internal controls, and for the preparation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States. Quanta’s independent registered public accounting firm is responsible for expressing an opinion as to whether the consolidated financial statements are free of material misstatements based on their audit. Our responsibility is to monitor and review these processes. In carrying out our role, we rely on Quanta’s management and independent registered public accounting firm.

We have reviewed and discussed Quanta’s audited consolidated financial statements with management. Management has confirmed to us that the financial statements have been prepared in conformity with accounting principles generally accepted in the United States.

In addition, we have discussed with PricewaterhouseCoopers LLP, Quanta’s independent registered public accounting firm, the matters required to be discussed by the statement on Auditing Standards No. 61, as amended, as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

We have received written disclosures and the letter from PricewaterhouseCoopers LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with us concerning independence, and we have discussed with PricewaterhouseCoopers LLP its independence from Quanta.

Based on our review and discussions referred to above, we recommended to Quanta’s Board of Directors that Quanta’s audited consolidated financial statements be included in Quanta’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010, for filing with the Securities and Exchange Commission.

AUDIT FEES

The Audit Committee of the Board has adopted a policy requiring pre-approval by the Audit Committee of all audit and permissible non-audit services to be provided by our independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. On an annual basis, the Audit Committee reviews and, as it deems appropriate, pre-approves the particular services to be provided by our independent registered public accounting firm and establishes specific budgets for each service. The term of any pre-approval is 12 months from the date of pre-approval, unless the Audit Committee specifically provides for a different period. The Audit Committee must be informed promptly of the provision by our independent registered public accounting firm of each service that is pre-approved by the Audit Committee. In addition, the Audit Committee may periodically revise the list of pre-approved services and related fee levels, based on subsequent determinations. Any services expected to exceed pre-approved fee levels require the specific pre-approval of the Audit Committee. The Audit Committee may delegate pre-approval authority to one or more of its members.

The following table details the aggregate fees billed by PricewaterhouseCoopers LLP, our independent registered public accounting firm, for fiscal years 2010 and 2009:

	2010		2009
Audit Fees(1)	$	1,747,800	$	2,019,000
Audit-Related Fees(2)		95,434		310,788
Tax Fees		—		—
All Other Fees(3)		790,887		69,988
Total	$	2,634,121	$	2,399,776

(1) Represents fees for professional services rendered for the audit of our annual consolidated financial statements and for reviews of our interim consolidated financial statements included on Form 10-Q, work relating to the evaluation of the effectiveness of Quanta’s internal control over financial reporting, state licensing pre-qualification filings and the statutory audit of one of our subsidiaries.

(2) Represents fees for professional services rendered for other assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements, including fees for consultations as to the accounting treatment of specific transactions based on current and proposed accounting standards, fees for consultations in connection with Quanta’s response to a series of SEC comment letters that were resolved during the period, as well as consultation fees related to the implementation of information technology solutions.

The Audit Committee has reviewed the services performed by PricewaterhouseCoopers LLP and the related fees and has considered whether the provision of non-audit services by PricewaterhouseCoopers LLP is compatible with maintaining the independence of PricewaterhouseCoopers LLP. During 2010, no fees for services outside the scope of audit, review, or attestation that exceed the waiver provisions of 17 CFR 210.2-01(c)(7)(i)(C) were approved by the Audit Committee.

PROPOSAL NO. 2

ADOPTION OF THE SHARE INCREASE AMENDMENT

TO QUANTA’S CERTIFICATE OF INCORPORATION

The Board is requesting stockholder approval of an amendment to Quanta’s Certificate of Incorporation to increase the number of shares of Common Stock that Quanta is authorized to issue from 300 million shares to 600 million shares (the “Share Increase Amendment”). The additional shares of Common Stock that would be authorized for issuance would have rights identical to the Common Stock currently outstanding. If the Share Increase Amendment is approved, the 300 million additional shares of Common Stock may be issued without further stockholder approval, unless a specific issuance requires stockholder approval under applicable law or under the listing requirements of any stock exchange on which Quanta’s shares are then listed.

The Board desires to have additional shares of Common Stock available for issuance to provide Quanta flexibility to use its capital stock for business and financial purposes in the future. In the future, Quanta may issue shares of Common Stock in connection with raising capital, establishing strategic relationships with other companies, expanding Quanta’s business or product lines through the acquisition of other businesses or products, providing equity incentives to directors, officers, employees or consultants and other purposes.

Among the factors considered, the Board determined that the Share Increase Amendment was advisable after comparing the number of shares currently authorized for issuance with the number of shares currently outstanding and the shares committed for issuance in the future. As of March 21, 2011,              shares of Common Stock were outstanding, an additional              shares were reserved for issuance upon exercise of outstanding options, and              shares were reserved and remained available for award under the 2007 Plan. The Board has reserved an additional 3,909,110 shares of Common Stock for issuance upon the exchange of Class A non-voting exchangeable common shares of Valard Construction Ltd., a British Columbia company and successor to Quanta Services EC Canada Ltd. If the Reclassification Amendment described in Proposal No. 3 (relating to the reclassification of each outstanding share of Limited Vote Common Stock into 1.05 shares of Common Stock) is adopted, then up to 454,110 shares of Common Stock will be issued to the former holders of the Limited Vote Common Stock. If the Reclassification Amendment is not adopted, 432,485 shares of Common Stock will remain reserved for issuance upon the conversion of Limited Vote Common Stock into Common Stock.

The Share Increase Amendment is not being proposed as a means of preventing or dissuading a change in control or takeover of Quanta. However, if the Share Increase Amendment is approved, the effect of the increase in proportion of authorized but unissued shares to issued and outstanding shares could enable the Board to render it difficult, or discourage an attempt, to obtain control of Quanta by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of present management. The Board would, unless prohibited by applicable law or stock exchange listing requirements, have additional shares available to effect transactions in which the number of outstanding shares would be increased and would thereby dilute the interest of any party attempting to gain control of Quanta as well as the interests of Quanta’s existing stockholders, possibly having a negative effect on the market price of the Common Stock. Further, such action could discourage an acquisition of Quanta which the stockholders might view as desirable. The Share Increase Amendment is not being proposed in response to any known effort or threat to acquire control of Quanta.

The Share Increase Amendment will not have an immediate effect on the rights of existing stockholders but, depending on the exact nature and circumstances of any actual issuances of shares, could have a number of effects on our stockholders at the time shares are issued. To the extent that additional authorized shares are issued in the future, such issuance will decrease existing stockholders’ percentage equity ownership interests and, depending upon the price at which such shares are issued, could be dilutive to existing stockholders.

53

The changes to Quanta’s Certificate of Incorporation that would be enacted if the Share Increase Amendment is adopted are set forth in Appendix A to this Proxy Statement. The foregoing description of the Share Increase Amendment is qualified in its entirety by the actual provisions of the Share Increase Amendment shown in Appendix A.

The Board has adopted the Share Increase Amendment, declared it advisable and recommends it for stockholder approval. The adoption of the Share Increase Amendment requires (i) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, voting together as a single class, and (ii) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, voting as a separate class. If the Share Increase Amendment is adopted by the stockholders, it will become effective when Quanta files a certificate of amendment of its Certificate of Incorporation with the Office of the Secretary of State of the State of Delaware.

If the stockholders approve one or more of Proposal Nos. 2, 3 or 4, the Board intends to file a Restated Certificate of Incorporation with the Office of the Secretary of State of the State of Delaware to integrate, into one document, the amendments to the Certificate of Incorporation and the other provisions of the Certificate of Incorporation.

The Board of Directors unanimously recommends a vote FOR adoption of the Share Increase Amendment to Quanta’s Certificate of Incorporation.

54

PROPOSAL NO. 3

ADOPTION OF THE RECLASSIFICATION AMENDMENT

TO QUANTA’S CERTIFICATE OF INCORPORATION

The Board is requesting stockholder approval of another amendment to Quanta’s Certificate of Incorporation that would reclassify, change and convert each outstanding share of Limited Common Stock into 1.05 shares of Common Stock (the “Reclassification Amendment”).

The shares of Limited Vote Common Stock were issued in 1997, shortly after Quanta was incorporated and prior to Quanta’s initial public offering of Common Stock. There are currently 432,485 shares of Limited Vote Common Stock outstanding. The shares of Limited Vote Common Stock have economic rights identical to the Common Stock, except with respect to voting rights. Holders of Limited Vote Common Stock are entitled to vote as a separate class to elect one director and do not vote in the election of other directors. Holders of Limited Vote Common Stock possess one-tenth of one vote per share on all other matters submitted for stockholder action. Subject to limited exceptions set forth in Quanta’s Certificate of Incorporation, when a stockholder disposes of a share of Limited Vote Common Stock, that share automatically converts into one share of Common Stock. The shares of Limited Vote Common Stock currently are not listed for trading on a securities exchange.

The Board has proposed the reclassification of the Limited Vote Common Stock into Common Stock in order to simplify Quanta’s capital structure and to eliminate the administrative costs associated with soliciting proxies from holders of Limited Vote Common Stock to elect one director. In addition, given that only 432,485 shares of Limited Vote Common Stock remain outstanding as of March 21, 2011, representing less than one-half of one percent (0.5%) of Quanta’s total market capitalization, the right of the remaining holders of the Limited Vote Common Stock to elect one member of the Board is substantially disproportionate to the aggregate economic interest in Quanta of the holders of Limited Vote Common Stock.

In May 2008, the Board established a special committee comprised of Messrs. Jackman, Ranck and Wood to oversee Quanta’s evaluation of available options in connection with potential transactions to acquire the Limited Vote Common Stock. The special committee concluded that any premium in the value of Limited Vote Common Stock due to the ability to elect one member of the Board was partially or fully offset by the limited voting rights and the conversion feature triggered upon a sale of the Limited Vote Common Stock. In addition, the special committee reviewed potential precedent transactions to aid in its consideration of an exchange ratio for potential exchange transactions. Upon analyzing the premiums paid in self tender transactions from 2002 to mid-2008 for shares representing 10% or less of the shares outstanding, excluding transactions at a discount, the special committee concluded that if any holder of Limited Vote Common Stock offered to exchange its shares, an exchange ratio of 1.05 shares of Common Stock for each share of Limited Vote Common Stock would be appropriate. During 2008, Quanta issued an aggregate 90,394 shares of Common Stock in exchange for an aggregate 86,088 shares of Limited Vote Common Stock, and during 2010, Quanta issued an aggregate 241,300 shares of Common Stock in exchange for an aggregate 229,808 shares of Limited Vote Common Stock, in each case through voluntary exchanges initiated by individual stockholders. The analysis of premiums paid in self tender transactions was updated through 2010, and the results were unchanged with respect to small self tender transactions ranging from $10 to $50 million. Based on these factors, the Board determined that the Reclassification Amendment and the related conversion ratio is in the best interests of Quanta and all of its stockholders. Two directors, namely Messrs. Ball and Foster, who own shares of Limited Vote Common Stock did not participate in the deliberations of the special committee and abstained in the Board’s approval of the Reclassification Amendment.

If the Reclassification Amendment is approved, each share of Limited Vote Common Stock will be reclassified, changed and converted into 1.05 shares of Common Stock, and the shares of Limited Vote Common Stock will cease to exist. The Reclassification Amendment would also delete all references to the Limited Vote Common Stock from Quanta’s Certificate of Incorporation. The shares of Common Stock issued as a result of the Reclassification Amendment will be identical to all other shares of Common Stock outstanding and will be listed

55

for trading on the New York Stock Exchange. If the Reclassification Amendment is approved, at future annual meetings, all of the directors will be elected by the holders of Common Stock and Series F Preferred Stock, voting as a single class. However, if Mr. Foster is elected by the holders of Limited Vote Common Stock to a new one-year term at the annual meeting, adoption of the Reclassification Amendment will not affect that term.

Fractional shares of Common Stock will not be issued in connection with the Reclassification Amendment, and instead any person who would otherwise be entitled to a fractional share of Common Stock will be entitled to receive a cash payment equal to such fraction multiplied by the closing price per share of Common Stock reported on the New York Stock Exchange on the date on which the reclassification occurs. If the stockholders approve the Reclassification Amendment, Quanta anticipates that the reclassification will occur on the date of the annual meeting. Stock certificates that represented shares of Limited Vote Common Stock will be deemed to represent the reclassified number of shares of Common Stock until those stock certificates are surrendered. Stockholders entitled to receive cash in lieu of fractional shares of Common Stock will receive payment following surrender of the stock certificates representing shares of Limited Vote Common Stock.

The changes to Quanta’s Certificate of Incorporation that would be enacted if the Reclassification Amendment is adopted are set forth in Appendix B to this Proxy Statement. The foregoing description of the Reclassification Amendment is qualified in its entirety by the actual provisions of the Reclassification Amendment shown in Appendix B.

The Board has adopted the Reclassification Amendment, declared it advisable and recommends it for stockholder approval. The adoption of the Reclassification Amendment requires (i) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, voting together as a single class, and (ii) the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Limited Vote Common Stock, voting as a separate class. If the Reclassification Amendment is adopted by the stockholders, it will become effective when Quanta files a certificate of amendment of its Certificate of Incorporation with the Office of the Secretary of State of the State of Delaware.

If the stockholders approve one or more of Proposal Nos. 2, 3 or 4, the Board intends to file a Restated Certificate of Incorporation with the Office of the Secretary of State of the State of Delaware to integrate, into one document, the amendments to the Certificate of Incorporation and the other provisions of the Certificate of Incorporation.

The Board of Directors recommends a vote FOR adoption of the Reclassification Amendment to Quanta’s Certificate of Incorporation.

56

PROPOSAL NO. 4

ADOPTION OF THE MISCELLANEOUS AMENDMENT

TO QUANTA’S CERTIFICATE OF INCORPORATION

The Board is requesting stockholder approval of an additional amendment to Quanta’s Certificate of Incorporation to enact a series of miscellaneous changes (the “Miscellaneous Amendment”). Each change is described below.

The Miscellaneous Amendment would delete a provision in Article FIFTH of Quanta’s Certificate of Incorporation that currently provides that directors are removable only for cause and only by the holders of a majority of the outstanding stock of Quanta. Under Delaware law, directors are removable with or without cause unless the board of directors is divided into classes serving staggered terms. Because Quanta’s Board is not divided into such classes, the directors are removable without cause. Accordingly, the Board is recommending the deletion of this provision in Article FIFTH to conform Article FIFTH to Delaware law. Following the deletion of this provision, director removal will be governed by the default provisions of Delaware law. Under these default provisions, a director may be removed without cause by the holders of a majority of the voting power of the outstanding stock entitled to elect that director, and a director may be removed with cause by the holders of a majority of the voting power of the outstanding stock entitled to vote at an election of directors. If the Miscellaneous Amendment is adopted, the Board will amend the Bylaws to make conforming changes to the provisions relating to director removal in the Bylaws.

The Miscellaneous Amendment would delete the provisions of Article TENTH from Quanta’s Certificate of Incorporation. Article TENTH currently provides, in part:

The Corporation will, to the fullest extent permitted by the Delaware General Corporation Law, . . . indemnify any and all persons it has power to indemnify under such law from and against any and all of the expenses, liabilities or other matters referred to in or covered by such law. Such indemnification may be provided pursuant to any Bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his director or officer capacity and as to action in another capacity while holding such office, will continue as to a person who has ceased to be a director, officer, employee or agent, and will inure to the benefit of the heirs, executors and administrators of such a person.

Quanta’s Bylaws currently provide rights to indemnification for its present and former directors and officers. Unlike the provisions of current Article TENTH, which may only be amended with the approval of the Board and Quanta’s stockholders, amendments to the indemnification provisions of the Bylaws may be amended either by the Board or the stockholders. Quanta is also a party to agreements with its directors and certain officers that establish indemnification rights for those persons. Because Quanta provides for indemnification in its Bylaws and in other agreements, the Board has determined that it is advisable to delete the provisions of Article TENTH. The indemnification rights offered by Quanta for actions or omissions occurring after the elimination of this Article TENTH would be provided for solely in the Bylaws, in any other indemnification agreements approved by Quanta and under Delaware law.

The Miscellaneous Amendment would also delete a provision in Article SEVENTH of Quanta’s Certificate of Incorporation that prescribes a quorum requirement for stockholder meetings. This provision may be amended only with the approval of the Board and the stockholders. The Board recommends the deletion of the quorum requirement from Quanta’s Certificate of Incorporation because, under Delaware law, the quorum requirements for stockholder meetings may be set forth in either the certificate of incorporation or the bylaws. Quanta’s Bylaws currently contain a quorum requirement that is the same as the quorum requirement in Article SEVENTH of Quanta’s Certificate of Incorporation. The Board and the stockholders will have greater flexibility to modify the quorum requirement for stockholder meetings in the future if the quorum is set forth solely in Quanta’s Bylaws because the Bylaws may be amended by either the Board or the stockholders. The Board does not have any present intention to amend the quorum requirement set forth in the Bylaws but may do so in the future.

57

The Miscellaneous Amendment would also delete a provision in Article FOURTH of Quanta’s Certificate of Incorporation, which, subject to limited exceptions, prohibits the Board from authorizing and issuing shares of a class or series of Preferred Stock that have rights that are different from other shares of the same class or series. The deletion of this provision would provide the Board greater flexibility in fixing the terms of Preferred Stock it may wish to issue in the future.

The changes to Quanta’s Certificate of Incorporation that would be enacted if the Miscellaneous Amendment is adopted are set forth in Appendix C to this Proxy Statement. The foregoing description of the Miscellaneous Amendment is qualified in its entirety by the actual provisions of the Miscellaneous Amendment shown in Appendix C.

The Board has adopted the Miscellaneous Amendment, declared it advisable and recommends it for stockholder approval. The adoption of the Miscellaneous Amendment requires the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, voting together as a single class. If the Miscellaneous Amendment is adopted by the stockholders, it will become effective when Quanta files a certificate of amendment of its Certificate of Incorporation with the Office of the Secretary of State of the State of Delaware.

If the stockholders approve one or more of Proposal Nos. 2, 3 or 4, the Board intends to file a Restated Certificate of Incorporation with the Office of the Secretary of State of the State of Delaware to integrate, into one document, the amendments to the Certificate of Incorporation and the other provisions of the Certificate of Incorporation.

The Board of Directors unanimously recommends a vote FOR adoption of the Miscellaneous Amendment to Quanta’s Certificate of Incorporation.

PROPOSAL NO. 5

APPROVAL OF THE QUANTA SERVICES, INC.

2011 OMNIBUS EQUITY INCENTIVE PLAN

Stockholders are being asked to approve the Quanta Services, Inc. 2011 Omnibus Equity Incentive Plan (the “2011 Plan”). The Board approved the 2011 Plan, subject to stockholder approval, on January 26, 2011. The purpose of the 2011 Plan is to attract and retain key personnel and to provide a means for directors, officers, employees, consultants and advisors to acquire and maintain an interest in Quanta, which interest may be measured by reference to the value of shares of our common stock. The 2011 Plan will supplement Quanta’s previously adopted 2007 Plan, and the shares of common stock remaining under the 2007 Plan may still be issued pursuant to awards made under such plan.

The principal terms of the 2011 Plan are summarized below and are qualified in their entirety by the full text of the 2011 Plan, which is attached as Appendix D to this Proxy Statement. A copy of the 2011 Plan may also be obtained without charge upon written request to Corporate Secretary, Quanta Services, Inc., 2800 Post Oak Blvd., Suite 2600, Houston, Texas 77056.

Administration. The Compensation Committee will administer the 2011 Plan, and subject to applicable regulations and the terms of the 2011 Plan described below, will have the authority to grant awards under the 2011 Plan, to interpret the 2011 Plan, to determine the terms and conditions of any agreements evidencing any awards granted under the 2011 Plan and to adopt, alter and repeal rules, guidelines and practices relating to the 2011 Plan. In addition, the Board may delegate to a committee consisting of one or more directors the authority to grant and set the terms of limited awards to eligible persons who are not executive officers or non-employee directors so long as the aggregate value of the awards granted by such committee in any calendar year does not exceed $1,000,000 (or $100,000 in any calendar year with respect to any individual), determined, in each case, based on the fair market value per share of common stock on the date an award is granted. The Board created the Equity Grant Committee for this purpose and appointed Mr. Colson as its sole member.

Eligibility. Employees, directors, officers, advisors or consultants of Quanta or its affiliates are eligible to participate in the 2011 Plan, as are prospective employees, directors, officers, consultants or advisors of Quanta who have agreed to serve us in those capacities.

Number of Shares Authorized. The 2011 Plan provides for an aggregate of 11,750,000 shares of common stock to be available for awards. No more than 5,000,000 shares may be subject to awards granted to all participants during any calendar year, and no more than 1,000,000 shares subject to awards may be granted to any individual during any calendar year. If any award is forfeited or if any option terminates, expires or lapses without being exercised, the shares subject to such award will again be made available for future grant. Shares of common stock that are used to pay the exercise price of an option or that are withheld to satisfy a participant’s tax withholding obligation will not be available for re-grant under the 2011 Plan. If there is any change in our corporate capitalization, the Compensation Committee in its sole discretion may make substitutions or adjustments to the number of shares reserved for issuance under the 2011 Plan, the number of shares covered by awards then outstanding under the 2011 Plan, the limitations on awards under the 2011 Plan, the exercise price of outstanding options and such other equitable substitution or adjustments as it may determine appropriate.

Awards Available for Grant. The Compensation Committee may grant awards of non-qualified stock options, incentive (qualified) stock options, stock appreciation rights, restricted stock awards, restricted stock units, stock bonus awards, performance compensation awards (including cash bonus awards) or any combination of the foregoing.

Options. The Compensation Committee will be authorized to grant options to purchase shares of common stock that are either “qualified,” meaning they are intended to satisfy the requirements of Section 422 of the Internal Revenue Code for incentive stock options, or “non-qualified,” meaning they are not intended to satisfy

59

the requirements of Section 422 of the Internal Revenue Code. Options granted under the 2011 Plan will be subject to the terms and conditions established by the Compensation Committee. Under the terms of the 2011 Plan, the exercise price of the options will not be less than the fair market value per share of our common stock at the time of grant. Options granted under the 2011 Plan will be subject to such terms, including the exercise price and the conditions and timing of exercise, as may be determined by the Compensation Committee, or if applicable, the Equity Grant Committee, and specified in the applicable award agreement. The maximum term of an option granted under the 2011 Plan will be ten years from the date of grant (or five years in the case of a qualified option granted to a 10% stockholder). Payment in respect of the exercise of an option may be made in cash or by check, or the Compensation Committee may, in its discretion and to the extent permitted by law, allow such payment to be made through a broker-assisted cashless exercise mechanism, a net exercise method, or by such other method as the Compensation Committee may determine to be appropriate.

Stock Appreciation Rights. The Compensation Committee will be authorized to award stock appreciation rights (or “SARs”) under the 2011 Plan. SARs will be subject to the terms and conditions established by the Compensation Committee. A SAR is a contractual right that allows a participant to receive, either in the form of cash, shares or any combination of cash and shares, the appreciation, if any, in the value of a share over a certain period of time. The strike price per common share for each SAR will not be less than the fair market value per share of our common stock at the time of grant. An option granted under the 2011 Plan may include SARs, and SARs may also be awarded to a participant independent of the grant of an option. SARs granted in connection with an option shall be subject to terms similar to the option corresponding to such SARs. The terms of the SARs shall be subject to terms established by the Compensation Committee and reflected in the award agreement.

Restricted Stock. The Compensation Committee will be authorized to award restricted stock under the 2011 Plan. Restricted stock is common stock that generally is non-transferable and is subject to other restrictions determined by the Compensation Committee for a specified period. Restrictions on restricted stock will lapse at such times determined by the Compensation Committee and specified in the applicable award agreement. If a participant terminates employment or services during the restricted period, then any unvested restricted stock is forfeited. The Compensation Committee will determine the terms of the restricted stock awards.

Restricted Stock Unit Awards. The Compensation Committee will be authorized to award restricted stock units under the 2011 Plan. Restricted stock units will vest at such times determined by the Compensation Committee and specified in the applicable award agreement. If a participant terminates employment or services during the period of time over which all or a portion of the units are to be earned, then any unvested units will be forfeited. The Compensation Committee will determine the terms of such restricted stock units. At the election of the Compensation Committee, the participant will receive a number of shares of common stock equal to the number of units earned or an amount in cash equal to the fair market value of that number of shares at the expiration of the period over which the units are to be earned.

Stock Bonus Awards. The Compensation Committee will be authorized to grant awards of unrestricted shares of common stock or other awards denominated in shares of common stock, either alone or in tandem with other awards, under such terms and conditions as the Compensation Committee may determine.

Performance Compensation Awards. The Compensation Committee will be authorized to grant restricted stock, restricted stock units, stock bonus awards or an award of a cash bonus under the 2011 Plan in the form of a performance compensation award intended to qualify as “performance-based compensation” under Section 162(m) of the Code by conditioning the vesting of the award on the satisfaction of certain performance goals. The maximum number of shares of common stock subject to a performance compensation award granted to a participant in any taxable year will not exceed 1,000,000 shares. The maximum amount of cash bonus payable pursuant to a performance compensation award to any participant under the 2011 Plan during any calendar year is $5 million. The Compensation Committee may establish these performance goals with reference to one or more of the following:

• net earnings or net income (before or after taxes);

60

• basic or diluted earnings per share (before or after taxes);

• net revenue or revenue growth;

• gross profit or gross profit growth;

• operating income or profit (before or after taxes);

• return measures (including, but not limited to, return on assets, capital, invested capital, equity or sales);

• cash flow (including, but not limited to, operating cash flow, free cash flow and cash flow return on capital);

• earnings before or after taxes, interest, depreciation, and/or amortization;

• gross or operating margins;

• productivity ratios;

• share price (including, but not limited to, growth measures and total stockholder return);

• expense targets;

• margins;

• operating efficiency;

• objective measures of customer satisfaction;

• working capital targets;

• measures of economic value added;

• inventory control;

• enterprise value;

• sales;

• debt levels and net debt;

• combined ratio;

• timely launch of new facilities;

• client retention;

• employee retention;

• performance relative to budget;

• safety performance targets;

• objective measures of personal targets, goals or completion of projects; or

• any combination of the foregoing.

To the extent permitted by law, the Compensation Committee may, in its sole discretion, change the criterion or criteria selected for purposes of establishing the performance goals without obtaining stockholder approval or modify the calculation of a performance goal under certain circumstances.

61

Transferability. Each award may be exercised during the participant’s lifetime only by the participant or, if permissible under applicable law, by the participant’s guardian or legal representative and may not be otherwise transferred or encumbered by a participant other than by will or by the laws of descent and distribution. The Compensation Committee, however, may permit awards (other than incentive stock options) to be transferred to family members, a trust for the benefit of such family members, a partnership or limited liability company whose partners or stockholders are the participant and his or her family members or anyone else approved by it or the Board.

Term and Amendment. The 2011 Plan will have a term of ten years and no further awards may be granted under the 2011 Plan after that date. The Board may amend, suspend or terminate the 2011 Plan at any time; however, stockholder approval to amend the 2011 Plan may be necessary if the law so requires. No amendment, suspension or termination will materially and adversely affect the rights of any participant or recipient of any award without the consent of the participant or recipient.

Change in Control. Except as may otherwise be provided in an award agreement or the employment agreement of a participant, in the event of a Change in Control (as defined in the 2011 Plan), all outstanding options and equity awards (other than performance compensation awards) issued under the 2011 Plan will become fully vested and free from restrictions and performance compensation awards will vest, as determined by the Compensation Committee, based on the level of attainment of the specified performance goals. The Compensation Committee may, in its discretion, cancel outstanding awards and pay the value of such awards to the participants in connection with a Change in Control.

Termination of Employment. Unless specifically provided otherwise in an award agreement or employment agreement, generally, upon a termination of employment (other than for Cause) (as defined in the 2011 Plan): (i) unvested stock options terminate and vested stock options may be exercised following the termination of a participant’s employment for a period of one year in the event of the participant’s death or Disability (as defined in the 2011 Plan) or 90 days in the event of a termination other than due to the participant’s death or Disability, provided that stock options may not be exercised after the expiration date set forth in a stock option agreement; (ii) unvested restricted stock, and restricted stock units are forfeited and terminate; and (iii) the right to receive any payment pursuant to performance compensation awards terminates.

U.S. Federal Income Tax Consequences

The following is a general summary of certain U.S. federal income tax consequences of the grant and exercise and vesting of awards under the 2011 Plan and the disposition of shares of common stock acquired pursuant to the exercise of such awards and is intended to reflect the current provisions of the Internal Revenue Code and the regulations thereunder. This summary is not intended to be a complete statement of applicable law, nor does it address foreign, state, local and payroll tax considerations. Moreover, the U.S. federal income tax consequences to any particular participant may differ from those described herein by reason of, among other things, the particular circumstances of such participant. It is intended that the 2011 Plan and any awards under the 2011 Plan comply with the provisions of Section 409A of the Internal Revenue Code so that participants will not be subject to adverse tax consequences under such section.

Options. No income will be realized by a participant upon grant of a non-qualified stock option. Upon the exercise of a non-qualified stock option, the participant will recognize ordinary compensation income in an amount equal to the excess, if any, of the fair market value of the shares underlying such options over the option exercise price paid at the time of exercise.

The Internal Revenue Code requires that, for treatment of an option as a qualified option, shares of common stock acquired through the exercise of a qualified option cannot be disposed of before the later of (i) two years from the date of grant of the option, or (ii) one year from the date of exercise. Holders of qualified options will generally incur no federal income tax liability at the time of grant or upon exercise of those options. However,

62

the spread at exercise will be an “item of tax preference,” which may give rise to “alternative minimum tax” liability for the taxable year in which the exercise occurs. If the holder does not dispose of the shares before two years following the date of grant and one year following the date of exercise, the difference between the exercise price and the amount realized upon disposition of the shares will constitute long-term capital gain or loss, as the case may be. Assuming both holding periods are satisfied, no deduction will be allowed to Quanta for federal income tax purposes in connection with the grant or exercise of the qualified option. If, within two years following the date of grant or within one year following the date of exercise, the holder of shares acquired through the exercise of a qualified option disposes of those shares, the participant will generally realize taxable compensation at the time of such disposition equal to the difference between the exercise price and the lesser of the fair market value of the share on the date of exercise or the amount realized on the subsequent disposition of the shares, and that amount will generally be deductible by Quanta for federal income tax purposes, subject to the possible limitations on deductibility under Sections 280G and 162(m) of the Internal Revenue Code for compensation paid to executives designated in those Sections. Finally, if an otherwise qualified option becomes first exercisable in any one year for shares having an aggregate value in excess of $100,000 (based on the grant date value), the portion of the qualified option in respect of those excess shares will be treated as a non-qualified stock option for federal income tax purposes.

Restricted Stock. A participant will not be subject to tax upon the grant of an award of restricted stock unless the participant otherwise elects to be taxed at the time of grant pursuant to Section 83(b) of the Internal Revenue Code. On the date an award of restricted stock becomes transferable or is no longer subject to a substantial risk of forfeiture, the participant will have taxable compensation equal to the difference between the fair market value of the shares on that date over the amount the participant paid for such shares, if any, unless the participant made an election under Section 83(b) of the Internal Revenue Code to be taxed at the time of grant. If the participant made an election under Section 83(b), the participant will have taxable compensation at the time of grant equal to the difference between the fair market value of the shares on the date of grant over the amount the participant paid for such shares, if any. Special rules apply to the receipt and disposition of restricted shares received by officers and directors who are subject to Section 16(b) of the Exchange Act.

Restricted Stock Units. A participant will not be subject to tax upon the grant of a restricted stock unit award. Rather, upon the delivery of shares or cash pursuant to a restricted stock unit award, the participant will have taxable compensation equal to the fair market value of the number of shares (or the amount of cash) the participant actually receives with respect to the award.

SARs. No income will be realized by a participant upon grant of an SAR. Upon the exercise of an SAR, the participant will recognize ordinary compensation income in an amount equal to the fair market value of the payment received in respect of the SAR.

Stock Bonus Awards. A participant will have taxable compensation equal to the difference between the fair market value of the shares on the date the shares of common stock subject to the award are transferred to the participant over the amount the participant paid for such shares, if any.

Deductions; Limitations. In general, Quanta will be entitled to a deduction in the amount equal to the income recognized by a participant in connection with an award under the 2011 Plan. However, certain limitations on the deductibility of such amounts may apply.

In general, Section 162(m) of the Internal Revenue Code denies a publicly held corporation a deduction for U.S. federal income tax purposes for compensation in excess of $1,000,000 per year per person to its principal executive officer and the three other officers (other than the principal executive officer and principal financial officer) whose compensation is disclosed in its proxy statement as a result of their total compensation, subject to certain exceptions. The 2011 Plan is intended to satisfy an exception with respect to grants of options to covered employees. In addition, the 2011 Plan is designed to permit certain awards of restricted stock, restricted stock units, cash bonus awards and other awards to be awarded as performance compensation awards intended to qualify under the “performance-based compensation” exception to Section 162(m) of the Internal Revenue Code.

63

In general, Section 280G of the Internal Revenue Code denies a deduction to a corporation with respect to certain payments and benefits provided to certain employees in connection with a change in control. As described above, the exercisability of a stock option or the elimination of restrictions on restricted stock and restricted stock units will be accelerated as a result of a Change in Control. If a Change in Control occurs, all or a portion of the value of the relevant award at that time may be a “parachute payment” under Section 280G of the Internal Revenue Code. This is relevant for determining whether a 20% excise tax (in addition to income tax otherwise owed) is payable by the participant as a result of the receipt of an “excess parachute payment” as determined under the Internal Revenue Code. Quanta will not be entitled to a deduction for that portion of any parachute payment which is subject to the excise tax.

Inapplicability of ERISA. Based upon current law and published interpretations, Quanta does not believe that the 2011 Plan is subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

New Plan Benefits

Future grants under the 2011 Plan will be made at the discretion of the Compensation Committee and, accordingly, are not yet determinable. In addition, the value of the awards granted under the 2011 Plan will depend on a number of factors, including the fair market value per share of our common stock on future dates, the exercise decisions made by the participants and/or the extent to which any applicable performance goals necessary for vesting or payment are achieved. Consequently, it is not possible to determine the benefits that might be received by participants receiving discretionary grants under, or having their annual bonus paid pursuant to, the 2011 Plan.

The Board has adopted the proposed 2011 Plan, declared it advisable and recommends it for stockholder approval. Approval of the proposed 2011 Plan requires the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, casting a vote on this proposal; provided that the voting power of the shares casting a vote represents over 50% of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, entitled to vote on this proposal.

The Board of Directors unanimously recommends a vote FOR approval of the Quanta Services, Inc. 2011 Omnibus Equity Incentive Plan.

PROPOSAL NO. 6

RATIFICATION OF THE APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2011. PricewaterhouseCoopers LLP has served as our independent public accounting firm since June 2002. We are asking our stockholders to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm. Although ratification is not required by our bylaws or otherwise, the Audit Committee is submitting the appointment of PricewaterhouseCoopers LLP to our stockholders for ratification as a matter of good corporate practice. In the event the stockholders do not ratify the appointment, the Audit Committee will reconsider the appointment. Even if the appointment is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of Quanta and its stockholders.

Representatives of PricewaterhouseCoopers LLP are expected to be present at the annual meeting with the opportunity to make a statement, if they choose, and to respond to appropriate questions.

Ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm requires the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, present at the meeting in person or by proxy and entitled to vote on this proposal.

The Board of Directors unanimously recommends a vote FOR ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm, and proxies executed and returned will be so voted unless contrary instructions are indicated thereon.

PROPOSAL NO. 7

ADVISORY VOTE ON EXECUTIVE COMPENSATION

The Board is committed to excellence in governance. As part of that commitment, and as required by Section 14A(a)(1) of the Exchange Act, the Board is providing Quanta’s stockholders with an opportunity to provide an advisory vote related to the compensation of Quanta’s NEOs, as described in the Compensation Discussion and Analysis section, the compensation tables and the accompanying narrative disclosure, set forth in this proxy statement.

The Compensation Committee establishes, recommends and governs all of the compensation and benefits policies and actions for the NEOs, as set forth herein under “Executive Compensation — Summary Compensation Table.” Additional information regarding the Compensation Committee and its role is described above in the “Compensation Discussion and Analysis” section of this proxy statement and the related tables and narrative disclosure.

Quanta’s compensation philosophy is designed to align our NEOs’ incentives with stockholder value creation; to attract, motivate and retain the best possible executive officer talent; to tie cash and stock incentives to the achievement of measurable company, business unit and individual performance goals that are linked to our long-term strategic plans; and to promote an ownership culture. Consistent with our compensation philosophy, Quanta’s executive compensation program links a substantial portion of compensation to both individual and company performance, with approximately two-thirds of total target NEO compensation each year being “at-risk” and, therefore, dependent upon performance against individual and company incentive targets. Moreover, equity-based awards provide an important role in our executive compensation program, providing alignment with stockholders, creating incentives for the increase of stockholder value and promoting an ownership culture. Finally, Quanta’s executive compensation program is designed to award superior performance and provide consequences for underperformance. The individual and company short-term and long-term performance goals, which were established during challenging economic times, were partially met in 2010, resulting in below-target awards to each NEO. Despite overall performance below target in 2010, equity nevertheless represents a substantial portion of executive compensation as a percentage of total compensation (base, short-term incentive and long-term equity). Specifically:

• Approximately 76% of total target compensation in 2010 for the CEO and approximately 66% of total target compensation in 2010 for the NEOs (other than the CEO) was “at risk” performance-based compensation pursuant to the incentive compensation plans described herein.

• Of the total direct compensation of the CEO for fiscal 2010, approximately 66% was in equity; 37% was in base salary and 21% in short-term incentive.

• For 2010, the total direct compensation of Messrs. Colson, O’Neil, Haddox, Trawick and Wilson was approximately 46%, 42%, 31%, 34% and 27%, respectively, below the median target direct total compensation of our peer group. The Compensation Committee believes that the actual total direct compensation for 2010 for Quanta’s NEOs is appropriate considering that Quanta did not fully achieve its financial performance goals and the individuals did not fully achieve their individual strategic goals for the 2010 performance year.

The Compensation Committee continually reviews best practices in governance and executive compensation. In observance of such best practices, Quanta:

• does not provide supplemental retirement benefits or non-qualified deferred compensation plans for the NEOs;

• has incentive plans that discourage undue risk and align executive rewards with short, medium and long term company performance; and

66

• encourages executives to have a meaningful ownership interest in the company and regularly reviews the NEOs’ holdings of Quanta common stock against pre-established ownership guidelines.

For the reasons discussed above, the Board unanimously recommends that stockholders vote in favor of the following resolution:

“RESOLVED, that the compensation of Quanta’s named executive officers, as described pursuant to the compensation disclosure rules of the Securities and Exchange Commission in Quanta’s proxy statement for the 2011 Annual Meeting of Stockholders, including without limitation, the Compensation Discussion and Analysis, the compensation tables and the accompanying narrative disclosure, is hereby APPROVED.”

Approval of the advisory resolution on Quanta’s executive compensation requires the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, present at the meeting in person or by proxy and entitled to vote on this proposal.

The results of this vote are not binding on the Board, whether or not the proposal is adopted by the aforementioned voting standard. While the resolution is non-binding, the Board values the opinions that stockholders express in their votes and in any additional dialogue. In evaluating the vote on this advisory resolution, the Board intends to consider the voting results in their entirety.

The Board of Directors unanimously recommends a vote FOR the advisory resolution approving Quanta’s executive compensation.

67

PROPOSAL NO. 8

ADVISORY VOTE ON FREQUENCY OF

FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION

As part of the Board’s commitment to excellence in corporate governance, and as required by the Section 14A(a)(2) of the Exchange Act, the Board is providing Quanta’s stockholders with an opportunity to provide an advisory vote to determine whether the stockholder vote on executive compensation should occur every one, two or three years.

Consistent with our compensation philosophy, Quanta’s executive compensation program promotes a performance-based culture and is designed to reward superior performance and attract and retain highly-qualified executives while aligning their interests with those of our stockholders. Equity comprises a significant component of the NEOs’ compensation, and such long-term awards generally vest over a three-year period from the date of grant. Furthermore, the Compensation Committee continually reviews best practices in governance and executive compensation and maintains a compensation program that complies with suggested best practices guidelines. In observance of such best practices, Quanta does not provide for the NEOs, unless generally available to all employees, supplemental retirement benefits, non-qualified deferred compensation plans or other perquisites, other than executive benefits under health and welfare plans, financial planning services, and limited availability of the partially-owned aircraft. Moreover, our incentive plans encourage executives to have a meaningful ownership interest in Quanta, discourage undue risk, and align executive rewards with short, medium and long term company performance. Quanta believes these factors, along with the rest of the compensation program as described more fully above in the “Compensation Discussion and Analysis” section of this proxy statement and the related tables and narrative disclosure, emphasize the positive pay practices employed by Quanta.

We believe holding an advisory vote on executive compensation every three years would allow Quanta to conduct a meaningful and detailed review of its pay practices in response to such stockholder advisory vote on executive compensation and that a more frequent vote is not necessary given the long-term nature of Quanta’s executive compensation program and Quanta’s compliance with best practices related to compensation.

For the reasons discussed above, the Board recommends that stockholders vote to hold the advisory vote on executive compensation every THREE years. Stockholders are not voting, however, to approve or disapprove of this particular recommendation. The proxy card provides for four choices, and stockholders are entitled to vote on whether the advisory vote on executive compensation should be held every one, two, or three years, or to abstain from voting.

With respect to the advisory vote on the frequency of future advisory votes on Quanta’s executive compensation, the voting option (1 year, 2 years or 3 years), if any, that receives the affirmative vote of a majority of the voting power of the shares of Common Stock, Limited Vote Common Stock and Series F Preferred Stock, considered together as a single class, present at the meeting in person or by proxy and entitled to vote on this proposal will be adopted by the stockholders, in accordance with Quanta’s Bylaws.

The results of this vote are not binding on the Board, whether or not it is adopted by the aforementioned voting standard. While the result of this advisory vote on the frequency of the vote on executive compensation is non-binding, the Board values the opinions that stockholders express in their votes and in any additional dialogue. In evaluating the vote on this advisory resolution, the Board will consider the voting results in their entirety. If one of the voting options is not adopted by the required vote of the stockholders, the Board will evaluate the votes cast for each of the voting options and will deem the voting option receiving the greatest number of votes to be the voting option approved by the stockholders.

The Board of Directors unanimously recommends a vote to conduct an advisory vote on executive compensation every THREE YEARS.

PROPOSED MISCELLANEOUS AMENDMENT

TO THE CERTIFICATE OF INCORPORATION

(Proposal No. 4)

Article FOURTH, paragraph (a) will be amended as follows:

(a) Preferred Stock may be issued in one or more series as may be determined from time to time by the Board of Directors. All shares of any one series of Preferred Stock will be identical except as to the dates of issue and the dates from which dividends on shares of the series issued on different dates will cumulate, if cumulative. Authority is hereby expressly granted to the Board of Directors to authorize the issuance of one or more series of Preferred Stock, and to fix by resolution or resolutions providing for the issue of each such series the voting powers, designations, preferences, and relative, participating, optional, redemption, conversion, exchange or other special rights, qualifications, limitations or restrictions of such series, and the number of shares in each series, to the full extent now or hereafter permitted by law.

The first paragraph of Article FIFTH will be amended as follows:

The number of directors of the Corporation shall be as specified in, or determined in the manner provided in, the Bylaws, but shall be at least one and not more than nineteen. Election of directors need not be by written ballot. A director of the Corporation may be removed only for cause and only upon the affirmative vote of the holders of a majority of the outstanding stock of the Corporation entitled to vote at an election of directors, subject to further restrictions on removal, not inconsistent with this Section, as may be contained in the bylaws.

Article SEVENTH will be amended as follows:

At all meetings of stockholders, a quorum will be present if the holders of a majority of the shares entitled to vote at the meeting are represented at the meeting in person or by proxy. From and after the first date as of which any class of the Corporation’s equity securities is traded on a national securities exchange, (i) any action required or permitted to be taken by the stockholders of the Corporation must be effected at an annual or special meeting of stockholders of the Corporation and may not be effected by any consent in writing by such stockholders and (ii) special meetings of the stockholders of the Corporation may be called only by the Chairman of the Board of Directors and shall be called within ten (10) days after receipt of the written request of the Board of Directors, pursuant to a resolution approved by a majority of the whole Board of Directors.

Article TENTH will be amended as follows:

TENTH. Reserved. (a) The Corporation will, to the fullest extent permitted by the Delaware General Corporation Law, as the same exists or may hereafter be amended, indemnify any and all persons it has power to indemnify under such law from and against any and all of the expenses, liabilities or other matters referred to in or covered by such law. Such indemnification may be provided pursuant to any Bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his director or officer capacity and as to action in another capacity while holding such office, will continue as to a person who has ceased to be a director, officer, employee or agent, and will inure to the benefit of the heirs, executors and administrators of such a person.

(b) If a claim under the preceding paragraph (a) is not paid in full by the Corporation within 30 days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant will be entitled to be paid also the expense of prosecuting such claim. It will be a defense to any such action (other than

C-1

an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct that make it permissible under the laws of the State of Delaware for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense will be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he has met the applicable standard of conduct set forth in the laws of the State of Delaware nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct, will be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

(b) Subject to the provisions of the Plan and applicable law, the Committee shall have the sole and plenary authority, in addition to other express powers and authorizations conferred on the Committee by the Plan, to: (i) designate Participants; (ii) determine the type or types of Awards to be granted to a Participant; (iii) determine the number of Common Shares to be covered by, or with respect to which payments, rights, or other matters are to be calculated in connection with, Awards; (iv) determine the terms and conditions of any Award; (v) determine whether, to what extent, and under what circumstances Awards may be settled or exercised in cash, Common Shares, other securities, other Awards or other property, or canceled, forfeited, or suspended and the method or methods by which Awards may be settled, exercised, canceled, forfeited, or suspended; (vi) determine whether, to what extent, and under what circumstances the delivery of cash, Common Shares, other securities, other Awards or other property and other amounts payable with respect to an Award shall be deferred either automatically or at the election of the Participant or of the Committee; (vii) interpret, administer, reconcile any inconsistency in, correct any defect in and/or supply any omission

D-6

in the Plan and any instrument or agreement relating to, or Award granted under, the Plan; (viii) establish, amend, suspend, or waive any rules and regulations and appoint such agents as the Committee shall deem appropriate for the proper administration of the Plan; (ix) accelerate the vesting or exercisability of, payment for or lapse of restrictions on, Awards; and (x) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan.

(c) The Committee may delegate to one or more officers of the Company or any Affiliate the authority to act on behalf of the Committee with respect to any matter, right, obligation, or election that is the responsibility of or that is allocated to the Committee herein, and that may be so delegated as a matter of law, except for grants of Awards to persons (i) subject to Section 16 of the Exchange Act or (ii) who are, or who are reasonably expected to be, “covered employees” for purposes of Section 162(m) of the Code.

(d) Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the Plan or any Award or any documents evidencing Awards granted pursuant to the Plan shall be within the sole discretion of the Committee, may be made at any time and shall be final, conclusive and binding upon all persons or entities, including, without limitation, the Company, any Affiliate, any Participant, any holder or beneficiary of any Award, and any shareholder of the Company.

(e) No member of the Board, the Committee, delegate of the Committee or any employee or agent of the Company (each such person, an “Indemnifiable Person”) shall be liable for any action taken or omitted to be taken or any determination made in good faith with respect to the Plan or any Award hereunder. Each Indemnifiable Person shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense (including attorneys’ fees) that may be imposed upon or incurred by such Indemnifiable Person in connection with or resulting from any action, suit or proceeding to which such Indemnifiable Person may be a party or in which such Indemnifiable Person may be involved by reason of any action taken or omitted to be taken under the Plan or any Award agreement and against and from any and all amounts paid by such Indemnifiable Person with the Company’s approval, in settlement thereof, or paid by such Indemnifiable Person in satisfaction of any judgment in any such action, suit or proceeding against such Indemnifiable Person, provided, that the Company shall have the right, at its own expense, to assume and defend any such action, suit or proceeding and once the Company gives notice of its intent to assume the defense, the Company shall have sole control over such defense with counsel of the Company’s choice. The foregoing right of indemnification shall not be available to an Indemnifiable Person to the extent that a final judgment or other final adjudication (in either case not subject to further appeal) binding upon such Indemnifiable Person determines that the acts or omissions of such Indemnifiable Person giving rise to the indemnification claim resulted from such Indemnifiable Person’s bad faith, fraud or willful criminal act or omission or that such right of indemnification is otherwise prohibited by law or by the Company’s constituent documents. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such Indemnifiable Persons may be entitled under the Company’s constituent documents, as a matter of law, or otherwise, or any other power that the Company may have to indemnify such Indemnifiable Persons or hold them harmless.

(f) Notwithstanding anything to the contrary contained in the Plan, the Board may, in its sole discretion, at any time and from time to time, grant Awards and administer the Plan with respect to such Awards. In any such case, the Board shall have all the authority granted to the Committee under the Plan.

5. Shares Subject to the Plan; Grant of Awards; Limitations.

(a) Subject to Section 12 of the Plan, the Committee is authorized to deliver under the Plan 11,750,000 Common Shares subject to Awards. The aggregate number of Common Shares subject to Awards granted in any one calendar year to all Participants shall not exceed 5,000,000 shares, and the aggregate number of Common Shares subject to an Award granted in any one calendar year to any individual shall not exceed 1,000,000 shares.

D-7

(b) The Committee may, from time to time, grant Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Stock Bonus Awards and/or Performance Compensation Awards to one or more Eligible Persons selected in its sole discretion; provided, however that the Equity Grant Committee may select the recipients of Awards other than Incentive Stock Options if (i) such recipients are not Officers or Eligible Directors, (ii) the aggregate value of the Awards granted in any one calendar year does not exceed $1,000,000 determined based on the Fair Market Value at the time of the grants, and (iii) the aggregate value of the Awards granted in any one calendar year to any individual does not exceed $100,000 determined based on the Fair Market Value at the time of the grants. A Participant may be granted more than one Award under the Plan, and Awards may be granted at any time or times during the term of the Plan. The grant of an Award to an Eligible Person shall not be deemed either to entitle that individual to, or to disqualify that individual from, participation in any other grant of Awards under the Plan.

(c) Use of Common Shares to pay the required Exercise Price or tax obligations, or shares not issued in connection with settlement of an Option or SAR or that are used or withheld to satisfy tax obligations of the Participant shall, notwithstanding anything herein to the contrary, not be available again for other Awards under the Plan. Shares underlying Awards under this Plan that are forfeited, cancelled, expire unexercised, or are settled in cash are available again for Awards under the Plan.

(d) Common Shares delivered by the Company in settlement of Awards may be authorized and unissued shares, shares held in the treasury of the Company, shares purchased on the open market or by private purchase, or a combination of the foregoing.

(e) Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by the Company or with which the Company combines (“Substitute Awards”). The number of Common Shares underlying any Substitute Awards shall be counted against the aggregate number of Common Shares available for Awards under the Plan.

6. Eligibility. Participation shall be limited to Eligible Persons who have entered into an Award agreement or who have received written notification from the Committee, or from a person designated by the Committee, that they have been selected to participate in the Plan.

7. Options.

(a) Generally. Each Option granted under the Plan shall be evidenced by an Award agreement (whether in paper or electronic medium (including email or the posting on a web site maintained by the Company or a third party under contract with the Company)). Each Option so granted shall be subject to the conditions set forth in this Section 7, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement. All Options granted under the Plan shall be Nonqualified Stock Options unless the applicable Award agreement expressly states that the Option is intended to be an Incentive Stock Option. Incentive Stock Options shall be granted only to Eligible Persons who are employees of the Company and its Affiliates, and no Incentive Stock Option shall be granted to any Eligible Person who is ineligible to receive an Incentive Stock Option under the Code. No Option shall be treated as an Incentive Stock Option unless the Plan has been approved by the shareholders of the Company in a manner intended to comply with the stockholder approval requirements of Section 422(b)(1) of the Code, provided that any Option intended to be an Incentive Stock Option shall not fail to be effective solely on account of a failure to obtain such approval, but rather such Option shall be treated as a Nonqualified Stock Option unless and until such approval is obtained. In the case of an Incentive Stock Option, the terms and conditions of such grant shall be subject to and comply with such rules as may be prescribed by Section 422 of the Code. If for any reason an Option intended to be an Incentive Stock Option (or any portion thereof) shall not qualify as an Incentive Stock Option, then, to the extent of such nonqualification, such Option or portion thereof shall be regarded as a Nonqualified Stock Option appropriately granted under the Plan.

D-8

(b) Exercise Price. The exercise price (“Exercise Price”) per Common Share for each Option shall not be less than 100% of the Fair Market Value of such share determined as of the Date of Grant; provided, however, that in the case of an Incentive Stock Option granted to an employee who, at the time of the grant of such Option, owns shares representing more than 10% of the voting power of all classes of shares of the Company or any Affiliate, the Exercise Price per share shall not be less than 110% of the Fair Market Value per share on the Date of Grant and provided further that, notwithstanding any provision herein to the contrary, the Exercise Price shall not be less than the par value per Common Share.

(c) Vesting and Expiration. Options shall (i) vest and become exercisable in such manner and on such date or dates, and (ii) expire after such period, not to exceed ten years (the “Option Period”), in each case as may be determined by the Committee and as set forth in an Award agreement; provided, however, that the Option Period shall not exceed five years from the Date of Grant in the case of an Incentive Stock Option granted to a Participant who on the Date of Grant owns shares representing more than 10% of the voting power of all classes of shares of the Company or any Affiliate; provided, further, that notwithstanding any vesting dates set by the Committee in the Award agreement, the Committee may, in its sole discretion, accelerate the exercisability of any Option, which acceleration shall not affect the terms and conditions of such Option other than with respect to exercisability. Unless otherwise provided by the Committee in an Award agreement: (i) the unvested portion of an Option shall expire upon termination of employment or service of the Participant granted the Option, and the vested portion of such Option shall remain exercisable for (A) one year following termination of employment or service by reason of such Participant’s death or Disability, but not later than the expiration of the Option Period or (B) 90 days following termination of employment or service for any reason other than such Participant’s death or Disability, and other than such Participant’s termination of employment or service for Cause, but not later than the expiration of the Option Period and (ii) both the unvested and the vested portion of an Option shall expire upon the termination of the Participant’s employment or service by the Company for Cause.

(d) Method of Exercise and Form of Payment. No Common Shares shall be delivered pursuant to any exercise of an Option until payment in full of the Exercise Price therefor is received by the Company and the Participant has paid to the Company an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld. Options that have become exercisable may be exercised by delivery of written notice of exercise or, if provided for, electronic notice of exercise, to the Company in accordance with the terms of the Option accompanied by payment of the Exercise Price. The Exercise Price shall be payable (i) in cash, check, cash equivalent and/or Common Shares having a Fair Market Value on the date of exercise equal to the Exercise Price (including, pursuant to procedures approved by the Committee, by means of attestation of ownership of a sufficient number of Common Shares in lieu of actual delivery of such shares to the Company), provided, that such Common Shares are not subject to any pledge or other security interest, and (ii) by such other method as the Committee may permit in accordance with applicable law, in its sole discretion, including without limitation: (A) in other property having a fair market value on the date of exercise equal to the Exercise Price or (B) if there is a public market for the Common Shares at such time, by means of a broker-assisted “cashless exercise” pursuant to which the Company is delivered a copy of irrevocable instructions to a stockbroker to sell the Common Shares otherwise deliverable upon the exercise of the Option and to deliver promptly to the Company an amount equal to the Exercise Price or (C) by a “net exercise” method whereby the Company withholds from the delivery of the Common Shares for which the Option was exercised that number of Common Shares having a Fair Market Value equal to the aggregate Exercise Price for the Common Shares for which the Option was exercised. Any fractional Common Shares shall be settled in cash. The Committee may specify a reasonable minimum number of Common Shares or a percentage of the shares subject to an Option that may be purchased on any exercise of an Option; provided, that such minimum number will not prevent Optionee from exercising the full number of Common Shares as to which the Option is then exercisable.

D-9

(e) Notification upon Disqualifying Disposition of an Incentive Stock Option. Each Participant awarded an Incentive Stock Option under the Plan shall notify the Company in writing immediately after the date the Participant makes a disqualifying disposition of any Common Shares acquired pursuant to the exercise of such Incentive Stock Option. A disqualifying disposition is any disposition (including, without limitation, any sale) of such Common Shares before the later of (A) two years after the Date of Grant of the Incentive Stock Option or (B) one year after the date of exercise of the Incentive Stock Option. The Company may, if determined by the Committee and in accordance with procedures established by the Committee, retain possession of any Common Shares acquired pursuant to the exercise of an Incentive Stock Option as agent for the applicable Participant until the end of the period described in the preceding sentence.

(f) Compliance With Laws, etc. Notwithstanding the foregoing, in no event shall a Participant be permitted to exercise an Option in a manner that the Committee determines would violate the Sarbanes-Oxley Act of 2002, if applicable, or any other applicable law or the applicable rules and regulations of the Securities and Exchange Commission or the applicable rules and regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or traded.

8. Stock Appreciation Rights.

(a) Generally. Each SAR granted under the Plan shall be evidenced by an Award agreement (whether in paper or electronic medium (including email or the posting on a web site maintained by the Company or a third party under contract with the Company)). Each SAR so granted shall be subject to the conditions set forth in this Section 8, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement. Any Option granted under the Plan may include tandem SARs. The Committee also may award SARs to Eligible Persons independent of any Option.

(b) Strike Price. The Strike Price per Common Share for each SAR shall not be less than 100% of the Fair Market Value of such share determined as of the Date of Grant

(c) Vesting and Expiration. A SAR granted in connection with an Option shall become exercisable and shall expire according to the same vesting schedule and expiration provisions as the corresponding Option. A SAR shall (i) vest and become exercisable in such manner and on such date or dates, and (ii) expire after such period, not to exceed ten years (the “SAR Period”), in each case as may be determined by the Committee and as set forth in an Award agreement; provided, however, that notwithstanding any vesting dates set by the Committee in the Award agreement, the Committee may, in its sole discretion, accelerate the exercisability of any SAR, which acceleration shall not affect the terms and conditions of such SAR other than with respect to exercisability. Unless otherwise provided by the Committee in an Award agreement: (i) the unvested portion of a SAR shall expire upon termination of employment or service of the Participant granted the SAR, and the vested portion of such SAR shall remain exercisable for (A) one year following termination of employment or service by reason of such Participant’s death or Disability, but not later than the expiration of the SAR Period or (B) 90 days following termination of employment or service for any reason other than such Participant’s death or Disability, and other than such Participant’s termination of employment or service for Cause, but not later than the expiration of the SAR Period and (ii) both the unvested and the vested portion of a SAR shall expire upon the termination of the Participant’s employment or service by the Company for Cause.

(d) Method of Exercise. SARs that have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company in accordance with the terms of the Award, specifying the number of SARs to be exercised and the date on which such SARs were awarded. Notwithstanding the foregoing, if on the last day of the Option Period (or in the case of a SAR independent of an Option, the SAR Period), the Fair Market Value of a Common Shares exceeds the Strike Price, the Participant has not exercised the SAR or the corresponding Option (if applicable), and neither the SAR nor the corresponding Option (if applicable) has expired, such SAR shall be deemed to have been exercised by the Participant on such last day and the Company shall make the appropriate payment therefor.

D-10

(e) Payment. Upon the exercise of a SAR, the Company shall pay to the Participant an amount equal to the number of shares subject to the SAR that are being exercised multiplied by the excess, if any, of the Fair Market Value of a Common Share on the exercise date over the Strike Price, less an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld. The Company shall pay such amount in cash, in Common Shares with a Fair Market Value equal to such amount, or any combination thereof, as determined by the Committee in an Award agreement. Any fractional Common Share shall be settled in cash.

9. Restricted Stock and Restricted Stock Units.

(a) Generally. Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an Award agreement (whether in paper or electronic medium (including email or the posting on a web site maintained by the Company or a third party under contract with the Company)). Each such grant shall be subject to the conditions set forth in this Section 9, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement.

(b) Restricted Stock – Accounts, Escrow or Similar Arrangement. Upon the grant of Restricted Stock, a book entry in a restricted account shall be established in the Participant’s name at the Company’s transfer agent and, if the Committee determines that the Restricted Stock shall be held by the Company or in escrow rather than held in such restricted account pending the release of the applicable restrictions, the Committee may require the Participant to additionally execute and deliver to the Company (i) an escrow agreement satisfactory to the Committee, if applicable, and (ii) the appropriate share power (endorsed in blank) with respect to the Restricted Stock covered by such agreement. If a Participant shall fail to execute an agreement evidencing an Award of Restricted Stock and, if applicable, an escrow agreement and blank share power within the amount of time specified by the Committee, the Award shall be null and void. Subject to the restrictions set forth in this Section 9 and the applicable Award agreement, the Participant generally shall have the rights and privileges of a shareholder as to such Restricted Stock, including without limitation the right to vote such Restricted Stock and the right to receive dividends, if applicable. To the extent shares of Restricted Stock are forfeited, any share certificates issued to the Participant evidencing such shares shall be returned to the Company, and all rights of the Participant to such shares and as a shareholder with respect thereto shall terminate without further obligation on the part of the Company.

(c) Vesting; Acceleration of Lapse of Restrictions. The Restricted Period shall lapse with respect to an Award of Restricted Stock or Restricted Stock Units at such times as provided by the Committee in an Award agreement, and the unvested portion of Restricted Stock and Restricted Stock Units shall terminate and be forfeited upon termination of employment or service of the Participant.

(d) Delivery of Restricted Stock and Settlement of Restricted Stock Units.

(i) Upon the expiration of the Restricted Period with respect to any shares of Restricted Stock, the restrictions set forth in the applicable Award agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award agreement. If an escrow arrangement is used, upon such expiration, the Company shall deliver to the Participant, or his beneficiary, without charge, the share certificate evidencing the shares of Restricted Stock that have not then been forfeited and with respect to which the Restricted Period has expired (rounded down to the nearest full share). Dividends, if any, that may have been withheld by the Committee and attributable to any particular share of Restricted Stock shall be distributed to the Participant in cash or, at the sole discretion of the Committee, in Common Shares having a Fair Market Value equal to the amount of such dividends, upon the release of restrictions on such share and, if such share is forfeited, the Participant shall have no right to such dividends (except as otherwise set forth by the Committee in the applicable Award agreement).

D-11

(ii) Unless otherwise provided by the Committee in an Award agreement, upon the expiration of the Restricted Period with respect to any outstanding Restricted Stock Units, the Company shall deliver to the Participant, or his beneficiary, without charge, one Common Share for each such outstanding Restricted Stock Unit; provided, however, that the Committee may, in its sole discretion, elect to (i) pay cash or part cash and part Common Share in lieu of delivering only Common Shares in respect of such Restricted Stock Units or (ii) defer the delivery of Common Shares (or cash or part Common Shares and part cash, as the case may be) beyond the expiration of the Restricted Period if such delivery would result in a violation of applicable law until such time as is no longer the case. If a cash payment is made in lieu of delivering Common Shares, the amount of such payment shall be equal to the Fair Market Value of the Common Shares as of the date on which the Restricted Period lapsed with respect to such Restricted Stock Units, less an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld.

10. Stock Bonus Awards. The Committee may issue unrestricted Common Shares, or other Awards denominated in Common Shares, under the Plan to Eligible Persons, either alone or in tandem with other awards, in such amounts as the Committee shall from time to time in its sole discretion determine. Each Stock Bonus Award granted under the Plan shall be evidenced by an Award agreement (whether in paper or electronic medium (including email or the posting on a web site maintained by the Company or a third party under contract with the Company)). Each Stock Bonus Award so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement.

11. Performance Compensation Awards.

(a) Generally. The Committee shall have the authority, at the time of grant of any Award described in Sections 9 or 10 of the Plan, to designate such Award as a Performance Compensation Award intended to qualify as “performance- based compensation” under Section 162(m) of the Code. The maximum number of Common Shares subject to a Performance Compensation Award granted to a Participant in any taxable year shall not exceed 1,000,000 Common Shares. The Committee shall also have the authority to make an award of a cash bonus to any Participant and designate such Award as a Performance Compensation Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code. The maximum cash bonus payable to a Participant pursuant to a Performance Compensation Award shall not exceed $5 million in any calendar year.

(b) Discretion of Committee with Respect to Performance Compensation Awards. With regard to a particular Performance Period, the Committee shall have sole discretion to select the length of such Performance Period, the type(s) of Performance Compensation Awards to be issued, the Performance Criteria that will be used to establish the Performance Goal(s), the kind(s) and/or level(s) of the Performance Goals(s) that is (are) to apply and the Performance Formula. Within the first 90 days of a Performance Period (or, if longer or shorter, within the maximum period allowed under Section 162(m) of the Code, if applicable), the Committee shall, with regard to the Performance Compensation Awards to be issued for such Performance Period, exercise its discretion with respect to each of the matters enumerated in the immediately preceding sentence and record the same in writing.

(c) Performance Criteria. The Performance Criteria that will be used to establish the Performance Goal(s) shall be based on the attainment of specific levels of performance of the Company (and/or one or more Affiliates, divisions, reportable segments or operational units, or any combination of the foregoing) and shall include one or more of the following: (i) net earnings or net income (before or after taxes); (ii) basic or diluted earnings per share (before or after taxes); (iii) net revenue or revenue growth; (iv) gross profit or gross profit growth; (v) operating income or profit (before or after taxes); (vi) return measures (including, but not limited to, return on assets, capital, invested capital, equity, or sales); (vii) cash flow (including, but not limited to, operating cash flow, free cash flow, and cash flow return on capital); (viii) earnings before or after taxes, interest, depreciation and/or amortization; (ix) gross or operating margins; (x) productivity ratios; (xi) share price (including, but not limited to, growth measures and total

D-12

shareholder return); (xii) expense targets; (xiii) margins; (xiv) operating efficiency; (xv) objective measures of customer satisfaction; (xvi) working capital targets; (xvii) measures of economic value added; (xviii) inventory control; (xix) enterprise value; (xx) sales; (xxi) debt levels and net debt; (xxii) combined ratio; (xxiii) timely launch of new facilities; (xxiv) client retention; (xxv) employee retention; (xxvi) performance relative to budget; (xxvii) safety performance targets and (xxviii) objective measures of personal targets, goals or completion of projects. Any one or more of the Performance Criteria may be used on an absolute or relative basis to measure the performance of a Participant and the Company (and/or one or more Affiliates, divisions, reportable segments or operational units, or any combination of the foregoing), as the Committee may deem appropriate, or any of the above Performance Criteria may be compared to the performance of a selected group of comparison companies or a published or special index that the Committee, in its sole discretion, deems appropriate, or as compared to various stock market indices. The Committee also has the authority to provide for accelerated vesting of any Award based on the achievement of Performance Goals pursuant to the Performance Criteria specified in this paragraph. To the extent required under Section 162(m) of the Code, the Committee shall, within the first 90 days of a Performance Period (or, if longer or shorter, within the maximum period allowed under Section 162(m) of the Code), define in an objective fashion the manner of calculating the Performance Criteria it selects to use for such Performance Period and thereafter promptly communicate such Performance Criteria to the Participant.

(d) Modification of Performance Goal(s). In the event that applicable tax and/or securities laws change to permit Committee discretion to alter the governing Performance Criteria without obtaining shareholder approval of such alterations, the Committee shall have sole discretion to make such alterations without obtaining shareholder approval. The Committee shall adjust or modify the calculation of a Performance Goal for a Performance Period, based on and in order to appropriately reflect the following events: (i) asset write-downs; (ii) litigation or claim judgments or settlements; (iii) the effect of changes in tax laws, accounting principles, or other laws or regulatory rules affecting reported results; (iv) any reorganization and restructuring programs; (v) extraordinary nonrecurring items as described in Accounting Principles Board Opinion No. 30 (or any successor pronouncement thereto) and/or in management’s discussion and analysis of financial condition and results of operations appearing in the Company’s annual report to shareholders for the applicable year; (vi) acquisitions or divestitures; (vii) any other specific unusual or nonrecurring events, or objectively determinable category thereof; (viii) foreign exchange gains and losses; and (ix) a change in the Company’s fiscal year.

(e) Payment of Performance Compensation Awards.

(i) Condition to Receipt of Payment. Unless otherwise provided in the applicable Award agreement, a Participant must be employed by the Company or an Affiliate of the Company on the date of payment with respect to a Performance Period to be eligible to receive such payment in respect of a Performance Compensation Award for the preceding Performance Period.

(ii) Limitation. A Participant shall be eligible to receive payment in respect of a Performance Compensation Award only to the extent that: (A) the Performance Goals for such period are achieved; and (B) all or some of the portion of such Participant’s Performance Compensation Award has been earned for the Performance Period based on the application of the Performance Formula to such achieved Performance Goals.

(iii) Certification. Following the completion of a Performance Period, the Committee shall review and certify in writing whether, and to what extent, the Performance Goals for the Performance Period have been achieved and, if so, calculate and certify in writing that amount of the Performance Compensation Awards earned for the period based upon the Performance Formula. The Committee shall then determine the amount of each Participant’s Performance Compensation Award actually payable for the Performance Period and, in so doing, may apply Negative Discretion.

D-13

(iv) Use of Negative Discretion. In determining the actual amount of an individual Participant’s Performance Compensation Award for a Performance Period, the Committee may reduce or eliminate the amount of the Performance Compensation Award earned under the Performance Formula in the Performance Period through the use of Negative Discretion if, in its sole judgment, such reduction or elimination is appropriate. The Committee shall not have the discretion, except as is otherwise provided in the Plan, to (A) grant or provide payment in respect of Performance Compensation Awards for a Performance Period if the Performance Goals for such Performance Period have not been attained; or (B) increase a Performance Compensation Award above the applicable limitations set forth in Section 5 of the Plan.

(f) Timing of Award Payments. Performance Compensation Awards granted for a Performance Period shall be paid to Participants as soon as administratively practicable following completion of the certifications required by this Section 11, but in no event later than two-and-one-half months following the end of the fiscal year during which the Performance Period is completed.

12. Changes in Capital Structure and Similar Events.

(a) Effect of Certain Events. In the event of (A) any dividend or other distribution (whether in the form of cash, Common Shares, other securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, amalgamation, consolidation, split-up, split-off, combination, repurchase or exchange of Common Shares or other securities of the Company, issuance of warrants or other rights to acquire Common Shares or other securities of the Company, or other similar corporate transaction or event (including, without limitation, a Change in Control) that affects the Common Shares, or (B) unusual or nonrecurring events (including, without limitation, a Change in Control) affecting the Company, any Affiliate, or the financial statements of the Company or any Affiliate, or changes in applicable rules, rulings, regulations or other requirements of any governmental body or securities exchange or inter-dealer quotation system, accounting principles or law, such that in either case an adjustment is determined by the Committee in its sole discretion to be necessary or appropriate, then the Committee shall make any such adjustments in such manner as it may deem equitable, including without limitation any or all of the following:

(i) adjusting any or all of (A) the number of Common Shares or other securities of the Company (or number and kind of other securities or other property) that may be delivered in respect of Awards or with respect to which Awards may be granted under the Plan (including, without limitation, adjusting any or all of the limitations under Section 5 of the Plan) and (B) the terms of any outstanding Award, including, without limitation, (1) the number of Common Shares or other securities of the Company (or number and kind of other securities or other property) subject to outstanding Awards or to which outstanding Awards relate, (2) the Exercise Price or Strike Price with respect to any Award or (3) any applicable performance measures (including, without limitation, Performance Criteria and Performance Goals);

(ii) providing for a substitution or assumption of Awards, accelerating the exercisability of, lapse of restrictions on, or termination of, Awards or providing for a period of time for exercise prior to the occurrence of such event; and

(iii) canceling any one or more outstanding Awards or portion thereof and causing to be paid to the holders thereof, in cash, Common Shares, other securities or other property, or any combination thereof, the value of such Awards, if any, as determined by the Committee (which if applicable may be based upon the price per Common Share received or to be received by other shareholders of the Company in such event), including without limitation, in the case of an outstanding Option or SAR, a cash payment in an amount equal to the excess, if any, of the Fair Market Value (as of a date specified by the Committee) of the Common Shares subject to such Option or SAR over the aggregate Exercise Price or Strike Price of such Option or SAR, respectively (it being understood that, in such event, any Option or SAR having a per share Exercise Price or Strike Price equal to, or in excess of, the Fair

D-14

Market Value of a Common Share subject thereto may be canceled and terminated without any payment or consideration therefor); provided, however, that in the case of any “equity restructuring” (within the meaning of the Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123 (Revised 2004)), the Committee shall make an equitable or proportionate adjustment to outstanding Awards to reflect such equity restructuring. Any adjustment in Incentive Stock Options under this Section 12 (other than any cancellation of Incentive Stock Options) shall be made only to the extent not constituting a “modification” within the meaning of Section 424(h)(3) of the Code, and any adjustments under this Section 12 shall be made in a manner that does not adversely affect the exemption provided pursuant to Rule 16b-3 under the Exchange Act. The Company shall give each Participant notice of an adjustment hereunder and, upon notice, such adjustment shall be conclusive and binding for all purposes.

(b) Effect of Change in Control. Unless specifically provided otherwise with respect to Change in Control events in an Award or in a then-effective written employment agreement between the Participant and the Company or an Affiliate, if, during the effectiveness of the Plan, a Change in Control occurs, (i) each Option and SAR which is at the time outstanding under the Plan shall automatically become fully vested and exercisable and free from restrictions immediately prior to the specified effective date of such Change in Control, for all Common Shares at the time subject to such, (ii) the Restricted Period shall expire and restrictions applicable to all outstanding Restricted Stock Awards and Restricted Stock Units shall lapse and such Awards shall become fully vested and (iii) Performance Periods in effect on the date the Change in Control occurs shall end on such date, and the Committee shall (A) determine the extent to which Performance Goals with respect to each such Performance Period have been met based upon such audited or unaudited financial information or other information then available as it deems relevant and (B) cause the Participant to receive partial or full payment of Awards for each such Performance Period based upon the Committee’s determination of the degree of attainment of the Performance Goals, or assuming that the applicable “target” levels of performance have been attained or on such other basis determined by the Committee. To the extent practicable, any actions taken by the Committee under this Section 12(b) shall occur in a manner and at a time which allows affected Participants the ability to participate in the Change in Control transactions with respect to the Common Shares subject to their Awards.

13. Amendments and Termination.

(a) Amendment and Termination of the Plan. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time; provided, that (i) no amendment to Section 11(c) or Section 13(b) (to the extent required by the proviso in such Section 13(b)) shall be made without shareholder approval and (ii) no such amendment, alteration, suspension, discontinuation or termination shall be made without shareholder approval if such approval is necessary to comply with any tax or regulatory requirement applicable to the Plan (including, without limitation, as necessary to comply with any rules or requirements of any securities exchange or inter-dealer quotation system on which the Common Shares may be listed or quoted or to prevent the Company from being denied a tax deduction under Section 162(m) of the Code); provided, further, that any such amendment, alteration, suspension, discontinuance or termination that would materially and adversely affect the rights of any Participant or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant, holder or beneficiary.

(b) Amendment of Award Agreements. The Committee may, to the extent consistent with the terms of any applicable Award agreement, waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Award theretofore granted or the associated Award agreement, prospectively or retroactively; provided that any such waiver, amendment, alteration, suspension, discontinuance, cancellation or termination that would materially and adversely affect the rights of any Participant with respect to any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant; provided, further, that without shareholder approval, except as otherwise permitted under Section 12 of the Plan, (i) no amendment or modification may reduce the

D-15

Exercise Price of any Option or the Strike Price of any SAR, (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or SAR, another Award or cash and (iii) the Committee may not take any other action that is considered a “repricing” for purposes of the shareholder approval rules of the applicable securities exchange or inter-dealer quotation system on which the Common Shares are listed or quoted.

14. Restrictive Covenants.

(a) Confidentiality. By accepting an Award under the Plan, and as a condition thereof, each Participant agrees not to, at any time, either during their employment or thereafter, divulge, use, publish or in any other manner reveal, directly or indirectly, to any person, firm, corporation or any other form of business organization or arrangement, and to keep in the strictest confidence any Confidential Information, except (i) as may be necessary to the performance of the Participant’s duties to the Company, (ii) with the Company’s express written consent, (iii) to the extent that any such information is in or becomes in the public domain other than as a result of the Participant’s breach of any of his or her obligations under this Section 14(a), or (iv) where required to be disclosed by court order, subpoena or other government process and in such event, the Participant shall cooperate with the Company in attempting to keep such information confidential to the maximum extent possible. Upon the request of the Company or an Affiliate, the Participant agrees to promptly deliver to the Company the originals and all copies, in whatever medium, of all such Confidential Information.

(b) Non-Disparagement. By accepting an Award under the Plan, and as a condition thereof, the Participant acknowledges and agrees that he or she will not defame or publicly criticize the services, business, integrity, veracity or personal or professional reputation of the Company, including its officers, directors, partners, executives or agents, in either a professional or personal manner at any time during or following his or her employment.

(c) Post-Employment Property. By accepting an Award under the Plan, and as a condition thereof, the Participant agrees that any work of authorship, invention, design, discovery, development, technique, improvement, source code, hardware, device, data, apparatus, practice, process, method or other work product whatever (whether patentable or subject to copyright, or not, and hereinafter collectively called “discovery”) related to the business of the Company that the Participant, either solely or in collaboration with others, has made or may make, discover, invent, develop, perfect, or reduce to practice during his or her employment, whether or not during regular business hours and created, conceived or prepared on the Company’s premises or otherwise shall be the sole and complete property of the Company. More particularly, and without limiting the foregoing, the Participant agrees that all of the foregoing and any (i) inventions (whether patentable or not, and without regard to whether any patent therefor is ever sought), (ii) marks, names, or logos (whether or not registrable as trade or service marks, and without regard to whether registration therefor is ever sought), (iii) works of authorship (without regard to whether any claim of copyright therein is ever registered), and (iv) trade secrets, ideas, and concepts ((i) to (iv) collectively, “Intellectual Property Products”) created, conceived, or prepared on the Company’s premises or otherwise, whether or not during normal business hours, shall perpetually and throughout the world be the exclusive property of the Company, as shall all tangible media (including, but not limited to, papers, computer media of all types, and models) in which such Intellectual Property Products shall be recorded or otherwise fixed. The Participant further agrees promptly to disclose in writing and deliver to the Company all Intellectual Property Products created during his or her engagement by the Company, whether or not during normal business hours. The Participant agrees that all works of authorship created by the Participant during his or her engagement by the Company shall be works made for hire of which the Company is the author and owner of copyright. To the extent that any competent decision-making authority should ever determine that any work of authorship created by the Participant during his or her engagement by the Company is not a work made for hire, by accepting an Award, the Participant assigns all right, title and interest in the copyright therein, in perpetuity and throughout the world, to the Company. To the extent that this Plan does not otherwise serve to grant or otherwise vest in the Company all rights in any Intellectual

D-16

Property Product created by the Participant during his or her engagement by the Company, by accepting an Award, the Participant assigns all right, title and interest therein, in perpetuity and throughout the world, to the Company. The Participant agrees to execute, immediately upon the Company’s reasonable request and without charge, any further assignments, applications, conveyances or other instruments, at any time, whether or not the Participant is engaged by the Company at the time such request is made, in order to permit the Company and/or its respective assigns to protect, perfect, register, record, maintain, or enhance their rights in any Intellectual Property Product; provided, that, the Company shall bear the cost of any such assignments, applications or consequences. Upon termination of the Participant’s employment by the Company for any reason whatsoever, and at any earlier time the Company so requests, the Participant will immediately deliver to the custody of the person designated by the Company all originals and copies of any documents and other property of the Company in the Participant’s possession, under the Participant’s control or to which he or she may have access.

For purposes of this Section 14, the term “Company” shall include the Company and its Affiliates.

15. General.

(a) Award Agreements. Each Award under the Plan shall be evidenced by an Award agreement, which shall be delivered to the Participant (whether in paper or electronic medium (including email or the posting on a web site maintained by the Company or a third party under contract with the Company)) and shall specify the terms and conditions of the Award and any rules applicable thereto, including without limitation, the effect on such Award of the death, Disability or termination of employment or service of a Participant, or of such other events as may be determined by the Committee.

(b) Nontransferability.

(i) Each Award shall be exercisable only by a Participant during the Participant’s lifetime, or, if permissible under applicable law, by the Participant’s legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant other than by will or by the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or an Affiliate; provided that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance.

(ii) Notwithstanding the foregoing, the Committee may, in its sole discretion, permit Awards (other than Incentive Stock Options) to be transferred by a Participant, without consideration, subject to such rules as the Committee may adopt consistent with any applicable Award agreement to preserve the purposes of the Plan, to: (A) any person who is a “family member” of the Participant, as such term is used in the instructions to Form S-8 under the Securities Act (collectively, the “Immediate Family Members”); (B) a trust solely for the benefit of the Participant and his or her Immediate Family Members; or (C) a partnership or limited liability company whose only partners or stockholders are the Participant and his or her Immediate Family Members; or (D) any other transferee as may be approved either (I) by the Board or the Committee in its sole discretion, or (II) as provided in the applicable Award agreement (each transferee described in clauses (A), (B) (C) and (D) above is hereinafter referred to as a “Permitted Transferee”); provided, that the Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan.

(iii) The terms of any Award transferred in accordance with the immediately preceding sentence shall apply to the Permitted Transferee, and any reference in the Plan, or in any applicable Award agreement, to a Participant shall be deemed to refer to the Permitted Transferee, except that (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the laws of descent and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred

D-17

Option unless there shall be in effect a registration statement on an appropriate form covering the Common Shares to be acquired pursuant to the exercise of such Option if the Committee determines, consistent with any applicable Award agreement, that such a registration statement is necessary or appropriate; (C) the Committee or the Company shall not be required to provide any notice to a Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Participant under the Plan or otherwise; and (D) the consequences of the termination of the Participant’s employment by, or services to, the Company or an Affiliate under the terms of the Plan and the applicable Award agreement shall continue to be applied with respect to the Participant, including, without limitation, that an Option shall be exercisable by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award agreement.

(c) Tax Withholding.

(i) A Participant shall be required to pay to the Company or any Affiliate, and the Company or any Affiliate shall have the right and is hereby authorized to withhold, from any cash, Common Shares, other securities or other property deliverable under any Award or from any compensation or other amounts owing to a Participant, the amount (in cash, Common Shares, other securities or other property) of any required withholding taxes in respect of an Award, its exercise, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Committee or the Company to satisfy all obligations for the payment of such withholding taxes.

(ii) Without limiting the generality of clause (i) above, the Committee may, in its sole discretion, permit a Participant to satisfy, in whole or in part, the foregoing withholding liability by (A) the delivery of Common Shares (which are not subject to any pledge or other security interest) owned by the Participant having a fair market value equal to such withholding liability or (B) having the Company withhold from the number of Common Shares otherwise issuable or deliverable pursuant to the exercise or settlement of the Award a number of shares with a fair market value equal to such withholding liability (but no more than the minimum required statutory withholding liability).

(d) No Claim to Awards; No Rights to Continued Employment; Waiver. No employee of the Company or an Affiliate, or other person, shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an Award, to be selected for a grant of any other Award. There is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants are similarly situated. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employ or service of the Company or an Affiliate, nor shall it be construed as giving any Participant any rights to continued service on the Board. The Company or any of its Affiliates may at any time dismiss a Participant from employment or discontinue any consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or any Award agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived any claim to continued exercise or vesting of an Award or to damages or severance entitlement related to non-continuation of the Award beyond the period provided under the Plan or any Award agreement, notwithstanding any provision to the contrary in any written employment contract or other agreement between the Company and its Affiliates and the Participant, whether any such agreement is executed before, on or after the Date of Grant.

(e) International Participants. With respect to Participants who reside or work outside of the United States of America and who are not (and who are not expected to be) “covered employees” within the meaning of Section 162(m) of the Code, the Committee may in its sole discretion amend the terms of the Plan or outstanding Awards with respect to such Participants in order to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment for a Participant, the Company or its Affiliates.

D-18

(f) Designation and Change of Beneficiary. Each Participant may file with the Committee a written designation of one or more persons as the beneficiary(ies) who shall be entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon his death. A Participant may, from time to time, revoke or change his beneficiary designation without the consent of any prior beneficiary by filing a new designation with the Committee. The last such designation received by the Committee shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant’s death, and in no event shall it be effective as of a date prior to such receipt. If no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be his or her spouse or, if the Participant is unmarried at the time of death, his or her estate.

(g) Termination of Employment/Service. Unless determined otherwise by the Committee at any point following such event or as otherwise provided in an Award agreement, service shall not be considered terminated in the case of (i) any approved leave of absence, (ii) transfers among the Company, any Affiliate, or any successor, in any capacity of any employee, director or consultant, or (iii) any change in status as long as the individual remains in the service of the Company or an Affiliate in any capacity of employee, director or consultant. An approved leave of absence shall include sick leave, military leave, or any other authorized personal leave. For purposes of each Incentive Stock Option, if such leave exceeds ninety (90) days, and re-employment upon expiration of such leave is not guaranteed by statute or contract, then the Incentive Stock Option shall be treated as a Non-Qualified Stock Option on the day that is three (3) months and one (1) day following the expiration of such ninety (90)-day period.

(h) No Rights as a Stockholder. Except as otherwise specifically provided in the Plan or any Award agreement, no person shall be entitled to the privileges of ownership in respect of Common Shares that are subject to Awards hereunder until such shares have been issued or delivered to that person.

(i) Government and Other Regulations.

(i) The obligation of the Company to settle Awards in Common Shares or other consideration shall be subject to all applicable laws, rules, and regulations, and to such approvals by governmental agencies as may be required. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any Common Shares pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel, satisfactory to the Company, that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the Common Shares to be offered or sold under the Plan. The Committee shall have the authority to provide that all certificates for Common Shares or other securities of the Company or any Affiliate delivered under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award agreement, the federal securities laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter-dealer quotation system upon which such shares or other securities are then listed or quoted and any other applicable federal, state, local or non-U.S. laws, and, without limiting the generality of Section 9 of the Plan, the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that it in its sole discretion deems necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject.

D-19

(ii) The Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of Common Shares from the public markets, the Company’s issuance of Common Shares to the Participant, the Participant’s acquisition of Common Shares from the Company and/or the Participant’s sale of Common Shares to the public markets, illegal, impracticable or inadvisable. If the Committee determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall pay to the Participant an amount equal to the excess of (A) the aggregate Fair Market Value of the Common Shares subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the shares would have been vested or delivered, as applicable), over (B) the aggregate Exercise Price or Strike Price (in the case of an Option or SAR, respectively) or any amount payable as a condition of delivery of Common Shares (in the case of any other Award). Such amount shall be delivered to the Participant as soon as practicable following the cancellation of such Award or portion thereof.

(iii) Notwithstanding any provision in this Plan to the contrary, any portion of an Award under the Plan shall be subject to a clawback to the extent necessary to comply with the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act or any Securities and Exchange Commission rule or applicable Company policy.

(j) Payments to Persons Other Than Participants. If the Committee shall find that any person to whom any amount is payable under the Plan is unable to care for his affairs because of illness or accident, or is a minor, or has died, then any payment due to such person or his estate (unless a prior claim therefor has been made by a duly appointed legal representative) may, if the Committee so directs the Company, be paid to his spouse, child, relative, an institution maintaining or having custody of such person, or any other person deemed by the Committee to be a proper recipient on behalf of such person otherwise entitled to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor.

(k) Nonexclusivity of the Plan. Neither the adoption of this Plan by the Board nor the submission of this Plan to the shareholders of the Company for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options or other equity-based awards otherwise than under this Plan, and such arrangements may be either applicable generally or only in specific cases.

(l) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate, on the one hand, and a Participant or other person or entity, on the other hand. No provision of the Plan or any Award shall require the Company, for the purpose of satisfying any obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made or otherwise to segregate any assets, nor shall the Company maintain separate bank accounts, books, records or other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall have no rights under the Plan other than as unsecured general creditors of the Company, except that insofar as they may have become entitled to payment of additional compensation by performance of services, they shall have the same rights as other employees under general law.

(m) Reliance on Reports. Each member of the Committee and each member of the Board shall be fully justified in acting or failing to act, as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent public accountant of the Company and its Affiliates and/or any other information furnished in connection with the Plan by any agent of the Company or the Committee or the Board, other than himself.

(n) Relationship to Other Benefits. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, profit sharing, group insurance or other benefit plan of the Company except as otherwise specifically provided in such other plan.

D-20

(o) Governing Law. The Plan shall be governed by and construed in accordance with the internal laws of the State of Delaware, without giving effect to the conflict of laws provisions thereof.

(p) Severability. If any provision of the Plan or any Award or Award agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any person or entity or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be construed or deemed stricken as to such jurisdiction, person or entity or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

(q) Obligations Binding on Successors. The obligations of the Company under the Plan shall be binding upon any successor corporation or organization resulting from the merger, amalgamation, consolidation or other reorganization of the Company, or upon any successor corporation or organization succeeding to substantially all of the assets and business of the Company.

(r) Code Section 162(m) Approval. If so determined by the Committee, the provisions of the Plan regarding Performance Compensation Awards shall be disclosed and reapproved by shareholders no later than the first shareholder meeting that occurs in the fifth year following the year in which shareholders previously approved such provisions, in each case in order for certain Awards granted after such time to be exempt from the deduction limitations of Section 162(m) of the Code. Nothing in this clause, however, shall affect the validity of Awards granted after such time if such shareholder approval has not been obtained.

(s) Expenses; Gender; Titles and Headings. The expenses of administering the Plan shall be borne by the Company and its Affiliates. Masculine pronouns and other words of masculine gender shall refer to both men and women. The titles and headings of the sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings shall control.

(t) Other Agreements. Notwithstanding the above, the Committee may require, as a condition to the grant of and/or the receipt of Common Shares under an Award, that the Participant execute lock-up, shareholder or other agreements, as it may determine in its sole and absolute discretion.

(u) Payments. Participants shall be required to pay, to the extent required by applicable law, any amounts required to receive Common Shares under any Award made under the Plan.

(v) Section 409A. The provisions of the Plan are intended to comply with the provisions of Section 409A of the Code and the regulations thereunder so as to avoid the imposition of an additional tax under Section 409A of the Code (a “409A Tax”). Notwithstanding any provision of the Plan to the contrary, if any provision of the Plan or Award agreement would result in the imposition of a 409A Tax, such provision shall be automatically reformed so as to avoid the imposition of a 409A Tax and such reformation shall be deemed to not have an adverse effect on a Participant’s rights with respect any Award.
