 GENERAL INFORMATION

 Place, Date and Time
             The Company's 2012 Annual Meeting of Shareholders ("Annual Meeting") will be held at the Heard Museum, 2301 North Central Avenue, Phoenix, Arizona 85004-1323, at 10:30 a.m., Mountain Standard Time, on Wednesday, May 16, 2012.

 Notice of Internet Availability
             Unless you elected to receive printed copies of the proxy materials in prior years, you will receive a Notice of Internet Availability of Proxy Materials by mail (the "Internet Notice"). The Internet Notice will tell you how to access and review the proxy materials. If you received an Internet Notice by mail and would like to receive a printed copy of the proxy materials, you should follow the instructions included in the Internet Notice.
             The Internet Notice is first being sent to shareholders on or about March 29, 2012. The Proxy Statement and the form of proxy relating to the Annual Meeting are first being made available to shareholders on or about March 29, 2012.

 Record Date; Shareholders Entitled to Vote
             All shareholders at the close of business on March 8, 2012 (the "record date") are entitled to vote at the meeting. Each holder of outstanding Company common stock is entitled to one vote per share held as of the record date on all matters on which shareholders are entitled to vote, except for the election of directors, in which case "cumulative" voting applies (see "Vote Required – Election of directors"). At the close of business on the record date, there were 109,365,892 shares of common stock outstanding.

 Voting
Vote by Internet . The website address for Internet voting is on the Internet Notice. Internet voting is available 24 hours a day.
Vote by telephone . The toll-free number for telephone voting is on your proxy card. Telephone voting is available 24 hours a day.
Vote by mail . You may vote by mail by promptly marking, signing, dating, and mailing a proxy card (a postage-paid envelope is provided for mailing in the United States).
Vote in person . You may come to and vote at the Annual Meeting. If you hold your shares in street name, you must obtain a proxy, executed in your favor, from the holder of record if you wish to vote these shares at the meeting.
If you vote by telephone or Internet, DO NOT mail a proxy card.
             You may change or revoke your vote at any time before the proxy is exercised by: filing with our Corporate Secretary either a notice of revocation or a signed proxy card bearing a later date; re-voting by telephone; or re-voting by Internet. Your proxy will be suspended with respect to your shares if you attend the meeting in person and so request, although attendance at the meeting will not by itself revoke a previously-granted proxy.

Table of Contents
             Your vote is confidential. Only the following persons have access to your vote: election inspectors; individuals who help with processing and counting of votes; and persons who need access for legal reasons.

 Quorum
             The presence, in person or by proxy, of a majority of the outstanding shares of our common stock is necessary to constitute a quorum at the Annual Meeting. In counting the votes to determine whether a quorum exists, shares that are entitled to vote but are not voted at the direction of the beneficial owner (called abstentions) and votes withheld by brokers in the absence of instructions from beneficial owners (called broker non-votes) will be counted for purposes of determining whether there is a quorum. Shares owned by the Company are not considered outstanding or present at the meeting.

 Vote Required
Election of directors . Individuals receiving the highest number of votes will be elected. The number of votes that a shareholder may, but is not required to, cast is calculated by multiplying the number of shares of common stock owned by the shareholder, as of the record date, by the number of directors to be elected. Any shareholder may cumulate his or her votes by casting them for any one nominee or by distributing them among two or more nominees. Abstentions will not be counted toward a nominee's total and will have no effect on the election of directors. You may not cumulate your votes against a nominee. If you hold shares beneficially through a broker, trustee or other nominee and wish to cumulate votes, you should contact your broker, trustee or nominee. If you would like to exercise your cumulative voting rights, you must do so by mail. The Company's Bylaws provide that, in an uncontested election, a director nominee who receives a greater number of votes cast "withheld" for his or her election than "for" such election will promptly tender his or her resignation to the Corporate Governance Committee. The Corporate Governance Committee is required to evaluate the resignation, taking into account the best interests of the Company and its shareholders, and will recommend to the Company's Board of Directors (the "Board") whether to accept or reject the resignation.
Under the current rules of The New York Stock Exchange ("NYSE"), your broker is not able to vote on your behalf in any director election unless you give your broker specific voting instructions. We encourage you to provide instructions so that your shares will be counted in the election of directors.
Say-on-Pay . The votes cast "for" must exceed the votes cast "against" to approve the advisory resolution on the compensation disclosed in this Proxy Statement of our Named Executive Officers – the Say-on-Pay vote. This resolution is not intended to address any specific item of compensation, but rather the overall compensation of the Named Executive Officers and the compensation philosophy, policies and procedures described in this Proxy Statement. Because your vote is advisory, it will not be binding on the Board or the Company. However, the Board will review the voting results and take them into consideration when making future decisions regarding executive compensation. Abstentions and broker non-votes will have no effect on the outcome of this proposal. We will hold an advisory vote on Say-on-Pay on an annual basis until we next hold an advisory vote of shareholders on the frequency of such votes as required by law.
Approval of the Pinnacle West Capital Corporation 2012 Long-Term Incentive Plan (the "2012 Plan") . Approval of the 2012 Plan requires the affirmative vote of a majority of the votes cast, provided that the total votes cast with respect to this proposal represent over fifty percent (50%) of the shares of common stock entitled to vote on the proposal. For purposes of approval of this proposal, abstentions have the effect of a vote against the proposal, and broker non-votes are not considered to be votes cast.

Table of Contents
Ratification of the appointment of the independent accountants . The votes cast "for" must exceed the votes cast "against" to ratify the appointment of the independent accountants for the year ending December 31, 2012. Abstentions and broker non-votes will have no effect on the outcome of this proposal.
The Board recommends a vote:
•
FOR the election of the nominated slate of directors (Proposal 1);
•
FOR the approval of the 2012 Plan (Proposal 2);
•
FOR the approval, on an advisory basis, of the resolution approving the compensation of our Named Executive Officers as disclosed in this Proxy Statement (Proposal 3); and
•
FOR the ratification of the appointment of Deloitte & Touche LLP ("D&T") as the Company's independent accountants for the year ending December 31, 2012 (Proposal 4).
             The Board is not aware of any other matters that will be brought before the shareholders for a vote. If any other matters properly come before the meeting, the proxy holders will vote on those matters in accordance with the recommendations of the Board or, if no recommendations are given, in accordance with their own judgment.

 Attendance at the Annual Meeting
             In order to attend the Annual Meeting, you will need to present a valid picture identification, such as a driver's license or passport, and either:
•
the Internet Notice or the top portion of your proxy card if you are a shareholder of record (each Internet Notice or proxy card admits two people); or
•

 Delivery of Annual Reports and Proxy Statements to a Shared Address; Obtaining a Copy of the Annual Report
             If you and one or more shareholders share the same address, it is possible that only one Internet Notice, Annual Report or Proxy Statement was delivered to your address. Registered shareholders at the same address who wish to receive separate copies of the Internet Notice, the Annual Report or Proxy Statement may:
•
call the Company's Shareholder Services at 1-602-250-5511;

 Shareholder Proposals or Director Nominations for the 2013 Annual Meeting
             To be included in the proxy materials for the 2013 Annual Meeting of Shareholders (the "2013 Annual Meeting"), any shareholder proposal intended to be presented at that meeting must be received by our Corporate Secretary no later than November 29, 2012 at the following address:
Corporate Secretary
Pinnacle West Capital Corporation
400 North Fifth Street, Mail Station 8602
Phoenix, Arizona 85004
             A shareholder who intends to present a proposal at the 2013 Annual Meeting, but does not wish it to be included in the 2013 proxy materials, must submit the proposal no earlier than January 16, 2013 and no later than the close of business on February 15, 2013. Nominations for the Board must be received by November 16, 2012. In all cases, shareholders must also comply with the applicable rules of the Securities and Exchange Commission ("SEC") and our Bylaws.

 Proxy Solicitation
             The Board is soliciting the enclosed proxy. The Company may solicit shareholders over the Internet, by telephone or by mail. The Company has retained D.F. King & Co., Inc., to assist in the distribution of proxy solicitation materials and the solicitation of proxies for $9,000, plus customary expenses. The costs of the solicitation will be paid by the Company. As required, the Company will reimburse brokerage houses and others for their out-of-pocket expenses in forwarding documents to beneficial owners of stock.

 INFORMATION ABOUT OUR BOARD AND CORPORATE GOVERNANCE
Director Independence
             NYSE rules require companies whose securities are traded on the NYSE to have a majority of independent directors. These rules describe certain relationships that prevent a director from being independent and require a company's board of directors to make director independence determinations in all other circumstances. The Company's Board has also adopted Director Independence Standards to assist the Board in making independence determinations. These Director Independence Standards are available on the Company's website at www.pinnaclewest.com .
             Based on the Board's review, the Board has determined that one of the Company's directors is not independent and that all of the other directors are independent. The 11 independent directors in 2011 were Messrs. Basha, Gallagher, Lopez, Nordstrom, and Parker, Drs. Cortese, Herberger and Klein, and Mses. Clark-Johnson, Grant and Munro. Mr. Brandt is not independent under the NYSE rules or the Director Independence Standards because of his employment with the Company. Mr. Parker resigned from his position as a director in February 2012. Ms. Grant will retire from the Board at the Annual Meeting.
             In accordance with the NYSE rules and the Director Independence Standards, the Board undertakes an annual review to determine which of its directors are independent. The review generally takes place in the first quarter of each year; however, directors are required to notify the Company of any changes that occur throughout the year that may impact their independence.

Table of Contents
             In considering the independence of Mr. Gallagher, the Board considered that the law firm of Gallagher & Kennedy, P.A. ("Gallagher & Kennedy"), where Mr. Gallagher is Chairman Emeritus, provided legal services to the Company in 2011 and is expected to provide legal services to the Company in 2012. However, since: (a) the amounts paid to Gallagher & Kennedy were less than the dollar thresholds set forth in the NYSE rules and the Director Independence Standards, and were less than one percent of the Company's and Gallagher & Kennedy's revenues for fiscal year 2011; (b) Mr. Gallagher does not furnish legal services to the Company; and (c) he has advised the Company that he receives no compensation or benefits from Gallagher & Kennedy as a result of the firm providing legal services to the Company, the Board determined that Mr. Gallagher was independent.
             Mr. Parker is Chairman and Chief Executive Officer of US Airways Group, Inc. and US Airways, Inc. (collectively "US Airways"), a commercial airline headquartered in Phoenix, Arizona, where the Company is also headquartered. In considering the independence of Mr. Parker, the Board considered that directors and employees of the Company and its subsidiaries purchase air travel from time to time for business purposes from US Airways. The Board determined that these matters did not impact Mr. Parker's independence because they were ordinary course, arms-length transactions that were not material to either the Company or US Airways. In addition, the amounts paid to US Airways were less than the dollar thresholds set forth in the NYSE rules and the Director Independence Standards and were less than one percent of the Company's and US Airways' revenues for fiscal year 2011.
             Ms. Clark-Johnson is an employee of Arizona State University ("ASU") in her capacity as the Executive Director of the Morrison Institute for Public Policy. Dr. Cortese is also an employee of ASU in his capacity as the Director of the ASU Health Care Delivery and Policy Program and a Foundation Professor in the Department of Biomedical Informatics, Ira A. Fulton School of Engineering and in the School of Health Management and Policy, W.P. Carey School of Business. ASU is considered a part of the reporting entity for the State of Arizona (the "State") for financial reporting purposes and, as such, the State is the entity considered in applying the independence tests. In considering the independence of Ms. Clark-Johnson and Dr. Cortese, the Board considered the fact that transactions between the State and the Company and its affiliates consist of providing electric service, utility-related construction, building leases, and the payment of various State fees, taxes, memberships and licenses. The Board determined that these matters do not impact Ms. Clark-Johnson's or Dr. Cortese's independence since amounts paid to or received from the State are less than the dollar thresholds set forth in the NYSE rules and the Director Independence Standards. In addition, neither of these directors benefits financially, directly or indirectly, from ASU's business relationships with the Company, most of which consist of receiving electric service at regulated rates.
             With respect to all of the directors, the Board considered that many of the directors and/or businesses of which they are officers, directors, shareholders, or employees are located in Arizona Public Service Company's ("APS") service territory and purchased electricity from APS at regulated rates in the normal course of business. The Board considered these relationships in determining the directors' independence, but, because the rates and charges for electricity provided by APS are fixed by the Arizona Corporation Commission ("ACC"), and the directors satisfied the other independence criteria specified in the NYSE rules and the Director Independence Standards, the Board determined that these relationships did not impact the independence of any director. The Board also considered contributions to charitable and non-profit organizations where a director also serves as a director of such charity or organization. However, since no director is also an executive officer of such charitable or non-profit organization, the Board determined that these payments did not impact the independence of any director.

 Board Meetings and Attendance
             In 2011, our Board held eight meetings and none of our directors attended fewer than 75% of the Board meetings and any meetings of committees on which he or she served. Each director is expected to be present at the Annual Meeting. All of the Board members attended the 2011 Annual Meeting.

 Board Committees
             The Board has the following standing committees: Audit; Corporate Governance; Finance; Human Resources; and Nuclear and Operating. All of the charters of the Board's committees are publicly available on the Company's website (www.pinnaclewest.com) . All of our committees are comprised of independent directors who meet the independence requirements of the NYSE rules, SEC rules, and the Director Independence Standards.

appoints the independent accountants and is responsible for their qualifications, independence, performance, and compensation;
•
reviews the performance of the Company's internal audit function; and
•
monitors the Company's compliance with legal and regulatory requirements that may have a material impact on the Company's financial statements.
             The Board has determined that each member of the Audit Committee meets the NYSE experience requirements and that Mr. Nordstrom, the Chair of the Audit Committee, is an "audit committee financial expert" under applicable SEC rules.

Table of Contents
Finance Committee
             The Finance Committee held four meetings in 2011. Among other things, the Finance Committee:
•
reviews the Company's historical and projected financial performance and the Company's financing plan and recommends approval of credit facilities and the issuance of long-term debt and common equity;
•
reviews and recommends approval of the Company's annual capital budget and reviews the annual operations and maintenance budget;
•
reviews and recommends approval of short-term investments and borrowing policies; and
•
reviews and recommends to the Board the Company's dividend actions.
Human Resources Committee
             The Human Resources Committee held five meetings in 2011. Among other things, the Human Resources Committee:
•
reviews management's programs for the attraction, retention, and development of the Company's human resources;
•
recommends persons for election as officers to the full Board;
•
annually reviews the goals and performance of our officers;
•
approves corporate goals and objectives relevant to the compensation of our Chief Executive Officer ("CEO"), assesses the CEO's performance in light of these goals and objectives, and sets the CEO's compensation level based on this assessment;
•
makes recommendations to the Board with respect to non-CEO executive compensation and director compensation; and
•
acts as the "committee" under our long-term incentive plans.
             Under the Human Resources Committee's charter, the Human Resources Committee may delegate authority to subcommittees, but did not do so in 2011. Additional information on the processes and procedures of the Human Resources Committee is provided under the "Compensation Discussion and Analysis."
Nuclear and Operating Committee
             The Nuclear and Operating Committee held four meetings in 2011. Among other things, the Nuclear and Operating Committee:
•
receives regular reports from management and monitors the overall performance of the Palo Verde Nuclear Generating Station ("Palo Verde");
•
reviews the results of major Palo Verde inspections and evaluations by external oversight groups, such as the Nuclear Regulatory Commission ("NRC") and the Institute of Nuclear Power Operations ("INPO");
•
reviews and monitors the power plant operations, energy delivery and customer service functions of the Company; and
•
reviews and monitors the Company's compliance with environmental, health and safety policies.
             In addition, the Nuclear and Operating Committee receives regular reports from the Offsite Safety Review Committee (the "OSRC"). The OSRC provides independent assessments of the safe and reliable operations of Palo Verde. Pursuant to Palo Verde's operating licenses, the OSRC focuses its
- 7 -

Table of Contents
assessment on operations, engineering, maintenance, safety, security and other support functions. The OSRC is comprised entirely of non-employee individuals with senior management experience in the nuclear industry and it meets periodically throughout the year.

 The Board's Leadership Structure
             Lead Director.     Kathryn L. Munro serves as the Company's Lead Director and chairs the Corporate Governance Committee. The Lead Director performs the following functions:
•
serves as a liaison between the Chairman of the Board (the "Chairman") and the independent directors;
•
advises the Chairman as to an appropriate schedule of Board meetings, reviews and provides the Chairman with input regarding agendas for the Board meetings and, as appropriate or as requested, reviews and provides the Chairman with input regarding information sent to the Board;
•
presides at all meetings at which the Chairman is not present, including executive sessions of the independent directors, which executive sessions are regularly scheduled as part of each Board meeting;
•
calls meetings of the independent directors when necessary and appropriate;
•
oversees the Board and Board committee self-assessment process;
•
is available for consultation and direct communication with the Company's shareholders and other interested parties; and
•
performs such other duties as the Board may from time to time delegate.
             Chairman and CEO Positions.     The Chairman is Donald E. Brandt, the Company's CEO. The Board believes that combining the roles of the CEO and Chairman enhances the Board's ability to communicate clearly and effectively with management, and that an independent Board Chairman would create an additional level of hierarchy that would only duplicate the activities already being vigorously carried out by its Lead Director.

 The Board's Role in Risk Oversight
             The ultimate responsibility for the management of the Company's risks rests with the Company's senior management team. The Board's oversight of the Company's risk management function is designed to provide assurance that the Company's risk management processes are well adapted to and consistent with the Company's business and strategy, and are functioning as intended. The Board focuses on fostering a culture of risk awareness and risk-adjusted decision-making and ensuring that an appropriate "tone at the top" is established. The Board regularly discusses and updates a listing of areas of risk and allocates responsibility for them among the Board committees. The charter for each of our committees requires each committee to periodically review risks in their respective areas. Each committee:
•
receives periodic presentations from management about its assigned risk areas;
•
assesses the effectiveness of the risk identification and mitigation measures being employed; and
•
discusses their assessments and recommendations with the full Board at least annually.
             Consistent with the requirements of the NYSE's corporate governance standards, the Audit Committee periodically reviews the Company's major financial risk exposures and the steps management has taken to monitor and control such exposures. The Audit Committee also reviews the comprehensiveness of the Board's risk oversight process and plays a coordinating role designed to ensure that no gaps exist in the coverage by the Board committees of risk areas. In recommending the

composition of the Board's committees and the selection of committee Chairs, the Corporate Governance Committee takes into account the effective functioning of the risk oversight role of each Board committee and the risk areas assigned to it.
             The Executive Risk Committee is comprised of senior level officers of the Company and is chaired by the Chief Financial Officer. Among other responsibilities, this Committee is responsible for ensuring that the Board receives timely information concerning the Company's material risks and risk management processes. The internal enterprise risk management group reports to the Vice President, Strategic Initiatives and Risk, who reports to the Chief Financial Officer of APS. The internal risk management group is responsible for (1) implementing a consistent risk management framework and reporting process across APS, and (2) ensuring that the Executive Risk Committee is informed of those processes and regularly apprised of material existing risks and the emergence of additional material risks.

 Director Qualification; Selection of Nominees for the Board
             Director Qualifications.     The Corporate Governance Guidelines contain Board membership criteria that apply to nominees recommended by the Corporate Governance Committee for a position on the Board. Under these criteria, a director must be a shareholder of the Company. In determining whether an individual should be considered for Board membership, the Corporate Governance Committee considers the following qualities, among others: integrity; strong business judgment and understanding of corporate governance; knowledge, including regulatory and political knowledge, and nuclear expertise at the strategic level; judgment; understanding of the Company's business environment; the potential contribution of each candidate to the diversity of backgrounds, experience and competencies which the Board desires to have represented, including large organizational leadership, public company experience and risk oversight skills; and technology and science experience to address the future of smart grids, communication technologies, control systems and renewable energy. The Board also considers an individual's accomplishments, skills, professional interests, personal qualities and other traits desirable in achieving an appropriate group of qualified individuals. The Board periodically reviews and revises these criteria.
             Selection of Nominees for the Board.     The Corporate Governance Committee uses a variety of methods to identify and evaluate nominees for a director position. The Corporate Governance Committee regularly assesses the appropriate size of the Board, whether any vacancies on the Board are expected due to retirement or otherwise, and whether the Board reflects the appropriate balance of knowledge, skills, expertise, and diversity required for the Board as a whole. In the event that vacancies are anticipated, or otherwise arise, the Corporate Governance Committee may consider various potential candidates. Candidates may be considered at any point during the year and come to the attention of the Corporate Governance Committee through current Board members, professional search firms or shareholders. The Corporate Governance Committee evaluates all nominees against the same criteria, regardless of the source of the nomination. Any shareholder nominations proposed for consideration by the Corporate Governance Committee should include the nominee's name and qualifications for Board membership and should be addressed to:
Corporate Secretary
Pinnacle West Capital Corporation
400 North Fifth Street, Mail Station 8602
Phoenix, Arizona 85004
             Any shareholder who wishes to submit a nomination for a director to the Board must deliver that nomination to our Corporate Secretary by November 16, 2012 and comply with the information requirements in the Company's Bylaws.

 Director Resignation Due to Substantial Change in Their Primary Business Position
             Under the Company's Corporate Governance Guidelines, upon a substantial change in a director's primary business position, a director is required to apprise the Corporate Governance Committee and to offer his or her resignation for consideration to the Corporate Governance Committee. The Corporate Governance Committee will recommend to the Board the action, if any, to be taken with respect to the tendered resignation.

 Communication with the Board
             Shareholders and other parties interested in communicating with the Board may do so by writing to the Corporate Secretary, Pinnacle West Capital Corporation, 400 North Fifth Street, Mail Station 8602, Phoenix, Arizona 85004, indicating who should receive the communication, for example, the Lead Director or the independent directors. The Corporate Secretary will transmit communications not otherwise specifically addressed and that raise substantial issues to the Lead Director and to the Chair of the Board Committee most closely associated with the matter. The Corporate Secretary has discretion to exclude communications that are commercial advertisements or other forms of solicitations, individual service or billing complaints and complaints related to individual employment-related actions.

 Codes of Ethics and Strategic Framework
             In order to ensure the highest levels of business ethics, the Board has adopted the Code of Ethics and Business Practices, which applies to all employees, officers and directors, and the Code of Ethics for Financial Executives, both of which are described below:
             Code of Ethics and Business Practices (the "Code of Ethics").     Employees and directors receive a copy of the Code of Ethics when they join the Company and are provided updates periodically. The Code of Ethics helps ensure that the employees, officers and directors of the Company and its subsidiaries act with integrity and avoid any real or perceived violation of the Company's ethics policy, laws, or regulations.
             Code of Ethics for Financial Executives.     The Company has adopted a Code of Ethics for Financial Executives, which is designed to promote honest and ethical conduct and compliance with applicable laws, rules, and regulations, particularly as related to the maintenance of financial records, the preparation of financial statements, and proper public disclosure. "Financial Executive" means the Company's CEO, Chief Financial Officer, Chief Accounting Officer, Controller, Treasurer, General Counsel, the President and Chief Operating Officer of APS, and other persons designated from time to time as a Financial Executive subject to this policy by the Chair of the Audit Committee.
             The Company provides periodic online training and examination covering the principles in the Code of Ethics. This training includes extensive discussion of the Company's values, an explanation of Company ethical standards, application of ethical standards in typical workplace scenarios, assessment questions to help measure understanding, and an electronic sign-off. All of the employees of the Company and APS, and all of our directors, complete the training.
             Both of the codes are available on the Company's website ( www.pinnaclewest.com ).
             The Company's Strategic Framework (the "Strategic Framework").     APS has adopted a strategic framework that defines its vision, mission, areas of focus, and values. APS's vision is to create a sustainable energy future for Arizona. APS's mission is to safely and efficiently generate and deliver reliable electric power and related services to its customers. The areas of focus are employees,

 SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
             Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company's directors and executive officers, and persons who own more than 10% of the Company's common stock to file reports of ownership and changes of ownership with the SEC.

 RELATED PARTY TRANSACTIONS
             The Corporate Governance Committee is responsible for reviewing and approving all transactions with any Related Party, which consists of any of our directors, director nominees, executive officers, shareholders owning more than 5% of the Company's common stock and, with respect to each of them, their immediate family members and certain entities in which they are an officer or a shareholder, partner, member or other participant who, directly or indirectly, has a substantial ownership interest in or otherwise substantially controls or shares control of such entity (a "Related Party"). This obligation is set forth in writing in our Statement of Policy Regarding Related Party Transactions (the "Policy").
             To identify Related Party Transactions, as defined in the Policy, each year the Company requires our directors and officers to complete director and officer questionnaires identifying any transactions with the Company in which a Related Party has an interest. We review Related Party Transactions due to the potential for a conflict of interest. A conflict of interest occurs when an individual's private interest interferes, or appears to interfere, in any way with our interests. The Code of Ethics requires all directors, officers, and employees who may have a potential or apparent conflict of interest to notify the Company's management. In addition, the Policy specifically provides that any Related Party Transaction must be approved or ratified by the Corporate Governance Committee. A "Related Party Transaction" is any transaction or a series of similar transactions in which the Company or any of its
- 16 -

subsidiaries is or was a participant, where the amount involved exceeds $120,000 in the aggregate, and in which any Related Party has a direct or indirect material interest, other than:
•
transactions in which rates or charges are fixed in conformity with law or governmental authority (such as APS rates approved by the ACC);
•
transactions in which the rates or charges are determined by competitive bid; or
•
the payment of compensation by the Company to the executive officers, directors, or nominees for directors.
             Based on the Policy, SEC rules and our review, we had no Related Party Transactions in 2011.

 REPORT OF THE HUMAN RESOURCES COMMITTEE
             The Human Resources Committee submitted the following report:
             The Human Resources Committee is composed of five non-employee directors, each of whom is independent as defined by NYSE rules and the Company's Director Independence Standards.
             In accordance with SEC rules, the Human Resources Committee discussed and reviewed the Compensation Discussion and Analysis with management and, based on those discussions and review, the Human Resources Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

 EXECUTIVE COMPENSATION
Compensation Discussion and Analysis ("CD&A")
Executive Summary
             Our compensation program is designed to be straightforward with an emphasis on rewarding performance. Our compensation objectives are to construct a program that aligns compensation with:
•
shareholder interests by tying compensation to shareholder returns;
•
business performance by tying compensation to specified business metrics;
•
individual performance by taking into account individual contributions in compensation decisions; and
•
retention of key individuals, which includes offering a program that is competitive.
             At the 2011 Annual Meeting of Shareholders, our shareholders overwhelmingly approved the compensation of our executive officers. As a result, while the Human Resources Committee (for purposes of this CD&A, the "Committee") reviewed and discussed developments in executive compensation practices, we made only modest modifications to our compensation program in 2011. The key elements of our program are:
•
Base salary – Messrs. Brandt, Hatfield, Falck and Robinson received a base salary increase in January 2011, but their base salaries remained at or near the median of our Comparator Group, which is defined later in this CD&A.
•
Annual cash incentive – the cash incentive is 100% performance-based and is tied to earnings, business unit performance and individual performance. Our incentive plans are structured so that we do not provide payment for poor performance. Earnings and all overall business unit performance metrics were achieved in 2011 in a range of 109% to 151% of the target for the metrics.
•
Three-year long-term equity grants of performance shares – payout of the performance shares is tied 50% to the Company's total shareholder return ("TSR") (stock price appreciation plus any dividends paid during the actual period) and 50% to six operational performance metrics.
•
Four-year equity grants of restricted stock units ("RSUs") – these vest in annual, equal increments over four years to encourage retention, and the value of the awards rise and fall with the Company's stock price. In February 2012, the Committee changed the allocation between future grants of performance shares and RSUs from 50%/50% to 55%/45% in order to further focus equity awards on the achievement of performance metrics.
•
Benefits – we offer benefits such as pension programs, deferred compensation programs, change of control agreements and limited perquisites in order to remain competitive and retain the talented executives that have made our Company successful.
•
Ownership guidelines – we require our Named Executive Officers to build and maintain a significant and continuing equity interest in the Company under our Stock Ownership Guidelines. In February 2012, the Committee increased the ownership requirement for the CEO to four times his base salary.
             During 2011, the Company granted a one-time Supplemental RSU (which is discussed later in this CD&A) to reward prior performance and encourage retention. As a result, largely due to the issuance of the Supplemental RSUs, the Company believes that the Summary Compensation Table does not reflect the 2011 compensation awarded to the Named Executive Officers as considered by the Committee in setting compensation and measuring performance. As such, the Company has included this Alternate 2011 Compensation Table, which differs from the Summary Compensation Table because
- 18 -

Table of Contents
it: (i) excludes the "Bonus" column since no amounts are shown in that column for 2011; (ii) excludes the full grant date fair value of the Supplemental RSUs that were granted to the Named Executive Officers in 2011 because the grants were primarily given in recognition of outstanding performance in 2010 and years preceding 2010; and (iii) excludes the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" and "All Other Compensation" columns, as the Committee did not directly consider these post-retirement benefits and de minimis perquisites in setting salary, annual cash incentives and equity awards for the Named Executive Officers for 2011.

             As discussed in the next section, we had a highly successful year in 2011, which had an effect on 2011 compensation due to our compensation program's pay-for-performance orientation.
Overview of 2011 Company Performance
             Pinnacle West is a holding company that derives substantially all of its revenues and earnings from APS, our vertically-integrated electric utility. Our 2011 accomplishments included:
•
The Company's share price increased 16.2%.
•
TSR increased $976 million in 2011 and $2.7 billion over the last three years.
•
TSR was 21.8%, 45.6% and 77.3% for 2011, 2010, and 2009, respectively. For the 2009-2011 period, the Company ranked 13 th  of 55 companies in the Edison Electric Institute utility index and sixth best within the Company's Comparator Group.
•
The Company achieved its safest year on record, placing us in the first quartile within the industry.
•
The NRC extended Palo Verde's operating licenses for 20 additional years.
•
We achieved our highest-ever ranking in the J.D. Power Index, a national customer satisfaction ranking. Our ranking improved by eight points from 2010. Nationally, APS ranked fourth among 55 large investor-owned utilities.
•
We achieved a customer reliability metric of 0.79 outages per customer compared to the industry median of 1.12 and the industry first quartile of 0.90.
•
APS entered into a settlement agreement of its pending retail rate case (the settlement agreement is still subject to the approval of the ACC).
•
We sold APS Energy Services Company, Inc., our competitive energy services subsidiary, in August 2011 for an after-tax gain of $10 million, effectively continuing our wind-down strategy for the Company's non-regulated businesses.
•
APS ranked 15 th  highest overall in Corporate Responsibility Magazine's "100 Best Corporate Citizens" and received the top utility ranking.

Compensation Objectives
             The fundamental objectives of the Company's executive compensation strategy are:
•
Alignment with Shareholder Interests . A significant portion of compensation should be tied to the Company's stock performance through performance-based or other stock incentives so that executives' interests are tied to the success of the Company and aligned with those of our shareholders.
•
Business Performance Accountability . Compensation should be tied to the Company's performance in several key areas, including furthering our Strategic Framework, so that executives are focused on specific strategic and operating objectives and are held accountable through their compensation for the performance of the Company.
•
Individual Performance Accountability . Compensation should be tied to an individual's performance so that individual contributions to the Company's performance are tangibly recognized.
•
Retention . Compensation should be designed to promote retention of key employees.
•
Competitiveness . The compensation program should be designed to attract leaders critical to the Company's success by providing total compensation levels and programs that are competitive.
Setting Executive Compensation
             The Human Resources Committee.     The Committee monitors executive officer compensation throughout the year and undertakes a thorough analysis of our executive officer compensation each Fall. This review includes consideration of competitive positions relative to specified labor markets, the mix of elements of compensation, the degree and type of performance focus, and a consideration of individual officer evaluations. From December through February, the Committee then makes adjustments to executive officer compensation, including salary and cash and non-cash incentives.
             Role of Executive Officers in Determining Executive Compensation.     The Committee makes all compensation decisions relating to our CEO's compensation, makes awards under the 2007 Long-Term Incentive Plan (the "2007 Plan"), will make awards under the 2012 Plan if that plan is approved by the shareholders, and determines the awards under the 2011 Incentive Plans, as defined later in this CD&A. The Committee recommends other executive officer compensation decisions, which are approved by the Board. Management works with the Committee in establishing the agenda for Committee meetings and in preparing meeting information. Management conducts evaluations and provides information on the performance of the executive officers for the Committee's consideration and provides such other information as the Committee may request. Management also assists the Committee in recommending salary levels; annual incentive plan structure and design, including earnings and business unit performance targets or other goals; long-term incentive plan structure and design, including award levels; and the type, structure, and amount of other awards. The executive officers are available to the Committee's compensation consultant to provide information as requested by the consultant. At the request of the Chair of the Committee, the CEO or other officers may attend and participate in portions of the Committee's meetings.
             Role of Compensation Consultants.     The Committee's charter gives the Committee the sole authority to retain and terminate any consulting firm used by the Committee in evaluating non-employee director and officer compensation. The Committee engaged Frederick W. Cook & Co. to assist the Committee in its evaluation of 2011 compensation for our executive officers (the "Consultant"). The Committee instructed the Consultant to prepare a competitive analysis of the compensation of the executive officers of the Company and of APS, and to make recommendations for changes to the existing compensation program, if warranted. The Consultant does not provide any

other services to the Company or any of its subsidiaries and, therefore, is independent from the Company.
             Consultant's Report and Comparator Group.     The Consultant reviewed our executive compensation practices and considered the extent to which these practices support our executive compensation strategy. As part of this study, the Consultant performed competitive pay comparisons for our executive officers based on:
•
compensation information as disclosed in 2010 SEC filings for the Comparator Group;
•
general industry data based on surveys published by Hewitt Associates, Inc. (averaging data for companies in the $2.5 – $5 billion revenue bracket and the $5 – $10 billion revenue bracket) and Towers, Perrin, Forster & Crosby, Inc. ("Towers Perrin") (averaging data for companies in the $3 – $6 billion revenue bracket and the $6 – $10 billion revenue bracket); and
•
industry-specific survey data from the Towers Perrin Energy Services Industry Survey (reflecting the average between companies in the $3 – $6 billion revenue bracket and companies with revenues greater than $6 billion).
             From these sources, the Consultant developed a competitive consensus in which the data for Messrs. Brandt, Hatfield, Falck and Robinson reflect one-third proxy statement data, one-third Energy Services Industry Survey, and one-third general industry surveys. For Mr. Edington there was not a general industry survey match, so the data reflect one-half proxy statement data and one-half Energy Services Industry Survey. Compensation levels were updated to July 2011 using a 3% annual growth factor that the Consultant indicated reflected projected executive-level market movement from major salary-planning surveys selected by the Consultant.
             As part of the executive compensation review for 2011, the Committee reviewed the Comparator Group for its continued appropriateness. As a result of such review, the Committee approved the use of the same Comparator Group that was used in setting 2010 executive compensation. The Comparator Group is broadly similar to the Company with respect to industry, complexity, business lines and size, and positions the Company close to the median with respect to revenues. The 2011 Comparator Group consisted of the following companies (the "Comparator Group"):

 Comparator Group

																	
  	 	Allegheny Energy	 	  	 	Alliant Energy	 	  	 	Ameren Corporation	 	  	 	DTE Energy Company	 	  	
  	 	Entergy Corporation	 	  	 	NextEra Energy (formerly
"FPL Group Inc.")	 	  	 	Northeast Utilities	 	  	 	NV Energy, Inc.	 	  	
  	 	OGE Energy Corporation	 	  	 	PPL Corporation	 	  	 	Progress Energy, Inc.	 	  	 	SCANA Corporation	 	  	
  	 	Southern Company	 	  	 	TECO Energy, Inc.	 	  	 	Wisconsin Energy Corporation	 	  	 	Xcel Energy, Inc.	 	  	
             In determining both the composition of the Comparator Group and the Company's relative position to that group, APS revenues were adjusted to take revenues attributable to managed assets, in addition to owned assets, into account. This adjustment was based on the following factors:
•
Palo Verde is the United States' largest nuclear generating facility, with a net generation rating of approximately 4,003 megawatts. APS owns 29.1% of Units 1 and 3 and owns or leases 29.1% of Unit 2; however, APS is responsible for the successful operation of 100% of the facility.
- 21 -

Table of Contents
•
Four Corners is a 5-unit coal-fired plant located in New Mexico, with a net generation rating of approximately 2,100 megawatts. APS owns Units 1, 2 and 3 and 15% of Units 4 and 5. However, similar to Palo Verde, APS is responsible for the successful operation of 100% of the facility.
•
While APS contracts with the other owners for reimbursement of costs attributable to them, APS is subject to additional business risks as the operator of 100% of the Palo Verde and the Four Corners plants.
             As a result, for purposes of its relative position in the Comparator Group, APS adjusted revenues from $3.3 billion to $5.2 billion. The adjustment places APS in the median of the Comparator Group for revenue. APS is also below the median for market capitalization and at approximately the median of the Comparator Group measured by number of employees, which further reinforced the Committee's conclusion that the Comparator Group was the appropriate group for benchmarking pay levels. The Committee believes that the senior executives of the Company face challenges in the operation of Palo Verde which require skill sets similar to those that executives at a number of the Comparator Group companies with nuclear operations also have, which reinforces the appropriateness of the inclusion of these companies for benchmarking purposes.
             In providing information to the Committee with respect to setting 2011 compensation, the Consultant reviewed the total compensation of the Named Executive Officers and the individual elements of that compensation, including the type of annual incentives and long-term incentives, and evaluated the competitiveness of the total compensation and individual elements of compensation of each such officer based on the survey data discussed above.
             In its analysis, presented in October 2010, the Consultant looked at competitive findings for base salary, base incentive, and long-term equity incentives to the Named Executive Officers as compared to the 25 th , 50 th  and 75 th percentile (base salary data was treated at the 50 th or the 75 th percentile if it was within +/- 10%). The conclusions of the report as to the comparative positions of the compensation of the Named Executive Officers are as follows:

	 	  	 	Actual Annual
Incentive as a

2  Messrs. Edington's and Falck's amounts include the annualized value of special deferred compensation awards of $1,000,000 and $50,000, respectively.
3  Mr. Edington's base salary was increased in June 2008 to $800,000 and has not been adjusted since then. The Consultant noted that factors supporting the appropriateness of Mr. Edington's compensation package are his critical skills, nuclear expertise, demand in the competitive market, and demonstrated performance to date by returning Palo Verde to an improved operational level. The Company pays 29.1% of Mr. Edington's compensation expense. The balance is paid by the other owners of Palo Verde.

             Application of the Committee's Judgment.     The analysis in the Consultant's report and its recommendations regarding the competitiveness and structure of compensation are factors that the Committee takes into account in its evaluation of compensation for the Named Executive Officers. The Committee considers how the Consultant's recommendations regarding particular elements of compensation may differ from management's recommendations. The Committee also focuses on the individual executives and their individual responsibilities, skills, expertise, value added through performance, and other external factors, and applies these views in conjunction with the information provided by the Consultant. The performance of each officer is formally reviewed each year by management and shared with the Committee. Individual performance evaluations consider individual goals and include a discussion of the officer's strengths and overall value to the Company. CEO performance is separately reviewed by the Committee.
             The Committee also considers written commitments in determining or recommending executive pay. For example, under the offer letters pursuant to which Messrs. Edington, Hatfield, and Falck were hired, each was entitled to a fixed starting salary and other specified benefits that are described in more detail below in the narrative disclosure accompanying the Summary Compensation Table and the 2011 Grants of Plan-Based Awards table. The Committee approved the terms of these offer letters after considering the entire compensation package in the context of the desirability of hiring these officers.
             Company, business unit, and individual officer performance, as well as compensation competitiveness, are the primary factors determining the level of total direct compensation for the Named Executive Officers. While the Committee considers internal pay equity in making compensation decisions, we do not have a policy requiring any set levels of internal pay differentiation. Finally, the Committee evaluates other factors that it considers relevant, such as the financial condition of the Company and APS. The Company does not have a pre-established policy or target for allocation between cash and non-cash compensation or between short-term and long-term incentive compensation. The Committee does allocate between the two forms of equity grants as stated in the "Executive Summary."
             As noted above, at our 2011 Annual Meeting, the shareholders cast an advisory vote on our executive compensation. The vote was not binding upon the Company, our directors or the Committee. Of the votes cast, 95% were "FOR" the compensation of the executives as disclosed in our 2011 Proxy Statement, excluding abstentions. The Committee was cognizant of this result in its consideration of the key components, design, implementation and amounts of our compensation program.
Compensation Design
             Performance-Based Compensation.     The Company believes that a significant portion of each Named Executive Officer's total compensation opportunity should be performance-based, reflecting both upside potential and downside risk. The illustrations that follow show the allocation of the Named Executive Officers' compensation between nonperformance-based (base salary) and performance-based (annual and other cash incentives, performance shares, and RSUs, excluding the Supplemental RSUs) components.

             Risk-Taking.     The compensation program is designed to reward performance but not encourage unacceptable risk-taking. The Committee evaluates the potential for unacceptable risk-taking in compensation design on an ongoing basis. We believe that the design of our executive compensation program does not unduly incentivize our executives to take actions that may conflict with our risk-based decision-making. Material risk in our compensation design is mitigated in several ways:
•
earnings goals and award opportunities in our annual cash incentive programs are at levels intended to be attainable without the need to take inappropriate risks;
•
our long-term incentives consist of time-based RSUs that vest over a multi-year period and performance shares that are earned at the end of a three-year period, both of which provide upside potential and downside risk; moreover, the use of RSUs in our long-term incentive program mitigates the likelihood of risk-taking because RSUs, as opposed to stock options, for example, retain some value even in a depressed market;
•
payouts are capped under the annual and long-term incentive plans;
•
more than one performance metric is used in our long-term performance share awards and the award opportunities under our annual incentive program are based on multiple considerations, thereby minimizing the ability of the executive to manipulate results;
•
the stock components inherent in our long-term incentive program, combined with our stock ownership guidelines and retention requirements, align the interests of our executives with a goal of long-term appreciation of shareholder value;
- 24 -

Table of Contents
•
compensation is generally targeted to the median of Comparator Group, thereby avoiding unusually high pay opportunities relative to Company peers; and
•
our program is consistent throughout the Company so that no one area or group is incentivized in a manner that would encourage risk-taking.
             In addition, the Committee has reviewed the overall compensation program for the Company's employees and has concluded that its program is balanced and does not encourage imprudent risk-taking. Employee compensation generally consists of some or all of the compensation components described in this CD&A.
              Executive Compensation Components
             The Company's executive compensation program consists of the following components:

             In addition, the Company provides pension programs, a deferred compensation program, change of control arrangements and limited perquisites.
             The chart below indicates how each element of our 2011 executive compensation program was intended to achieve our stated compensation objectives of aligning the interests of executives and

 Base Salary
             The Committee reviews competitive salary information and individual salaries for executive officers on an annual basis. The Named Executive Officers do not have a contractual right to receive a fixed base salary, except that a starting annual base salary was often specified when the officer was hired. In considering individual salaries, the Committee reviews the scope of job responsibilities, individual contributions, business performance, retention concerns, and current compensation compared to market practices. In setting base salaries, the Committee also considers that base salary is used as the basis for calculating annual incentive awards. The Company sets the amount of base salary toward the median of the Comparator Group, except in the case of Mr. Edington, whose current salary was set in 2008.
             In January 2011, the Committee, based on the considerations set forth above, made the following adjustments to the base salaries of the following Named Executive Officers for fiscal year 2011:

													
  	 	 Name	 	  	 	2010 Base Salary
($)	 	  	 	2011 Base Salary
($)	 	  	
   	 	 Mr. Brandt	 	  	 	960,000	 	  	 	1,091,000	 	  	
  	 	 Mr. Hatfield	 	  	 	468,000	 	  	 	   490,000	 	  	
   	 	 Mr. Falck	 	  	 	459,000	 	  	 	   473,000	 	  	
  	 	 Mr. Robinson	 	  	 	550,000	 	  	 	   610,000	 	  	
             These adjustments resulted in these four Named Executive Officers being at or near the median of the Comparator Group.

 Annual Incentives
             We have used annual cash incentive programs for all our employees for a number of years. The performance criteria that underlie the annual incentive programs generally focus on the Strategic Framework and the following objectives (the "General Performance Objectives"):
•
shareholder value creation;
•
customer service;
•
financial strength;
•
operating performance;
•
safety; and
•
an assessment of individual performance.
             We use the annual incentive programs to further the Strategic Framework and achieve the General Performance Objectives.
             In order to promote specific goals for 2011, the Committee approved the Pinnacle West 2011 Annual Incentive Award Plan (the "CEO Incentive Plan") in December 2010, which covers Mr. Brandt. Also in December 2010, acting on the recommendation of the Committee, the Board approved the APS 2011 Annual Incentive Award Plan (the "APS Incentive Plan"), which covers Messrs. Hatfield, Falck, and Robinson, and the 2011 APS Palo Verde Employee Incentive Plan (the "Palo Verde Incentive Plan"), which covers Mr. Edington. The APS Incentive Plan and the Palo Verde Incentive Plan are collectively referred to as the "APS Incentive Plans," and the APS Incentive Plans and the CEO Incentive Plan are collectively referred to as the "2011 Incentive Plans."

             The 2011 Incentive Plans also allow the Committee to consider the General Performance Objectives and individual performance.
             In respect of the earnings measures, the calculated incentive award is proportional to the actual earnings achieved and begins when earnings exceed any indicated threshold performance level. In designing the 2011 Incentive Plans, the Committee set the target earnings level based on a reasonable range of expectations for the year, while taking into account prior year performance and current economic conditions.
             Individual business unit goals that could be directly correlated to earnings were set at levels that, if achieved at target, would contribute to earnings being achieved at target. However, some of the metrics, like safety and customer satisfaction, are not directly correlated to earnings, and are instead set with reference to prior year performance and a reasonable range of expectations of performance of comparable companies in our industry.
             The business unit performance measures are tied to the components of our Strategic Framework.
The following table details the business unit performance measures under the 2011 Incentive Plans, as correlated to the Strategic Framework, and compares the targets to actual results. For Fossil Generation and Palo Verde, minimum performance targets were required to be met before any award could be made and these performance targets were met.

              Mr. Brandt .     Under the CEO Incentive Plan, the 2011 target earnings level of $327 million was exceeded as Pinnacle West's 2011 earnings were $340.7 million. That result equates to 36% of the earnings range between target and maximum and a total achievement level of 136% of target. Based upon earnings only, Mr. Brandt's potential award was $1,483,760. As permitted by the CEO Incentive Plan, the Committee further took into account the Company's strong showing in the General Performance Objectives in determining Mr. Brandt's total award, including the significant increase in TSR and stock price, the improvement in the Company's credit ratings and the strengthened financial condition of the Company. As a result of these factors, the Committee awarded Mr. Brandt $1,636,500, the maximum award.
              Other Named Executive Officers .     Under the APS Incentive Plans, the 2011 target earnings level of $333 million was exceeded as APS earnings were $336.2 million. That result equates to 9% of the earnings range between target and maximum and a total achievement of 109% of target. This earnings achievement combined with the applicable business unit performance results set forth above resulted in the indicated incentive awards, without further adjustment, for Messrs. Edington, Falck and Hatfield. As permitted by the APS Incentive Plan, Mr. Robinson's calculated award based on earnings ($602,528) was adjusted by the Committee in light of the Company's consistent performance in excess of target across the range of plan indicators as well as the General Performance Objectives. As a result, the Committee awarded Mr. Robinson $647,820 under the APS Incentive Plan (compared to a maximum award potential of $915,000).

             In December 2010, the Board approved a separate award opportunity for Mr. Edington, as provided in his offer letter, of up to $125,000 for the achievement of various Palo Verde operational targets during 2011. We describe this award in more detail in the narrative disclosure accompanying the Summary Compensation Table and the 2011 Grants of Plan-Based Awards table. In January 2012, Mr. Brandt determined that the performance metrics were met and approved an award amount of $125,000 under this opportunity for Mr. Edington.
Long-Term Incentives
             The Company currently uses two types of equity grants: performance shares and RSUs. In 2011, awards consisted of 50% of each type of grant. The regular 2011 grants to the Named Executive Officers that were part of the Committee's 2011 compensation decisions were as follows:

1  Based on the closing price of Pinnacle West common stock on the date of grant of $41.71 per share and the 2011 Performance Shares valued at 100% of the Base Grant.
             We use performance shares because we believe they effectively tie long-term compensation to shareholder value, and we use RSUs to allow us to balance the goals of maximizing performance and promoting officer retention. Time-based RSUs also assist in mitigating risk incentives.
             To determine the amount of performance share and RSU awards, the Committee first establishes a target compensation value for each officer that it wants to deliver through long-term equity awards opportunities. The Committee considers various factors, including the retention value of the total compensation package, the long-term equity component in light of the competitive environment, and individual performance. The Committee also considers target value in light of the Company's achievement of earnings targets and overall performance. Once the target value is established, the Committee determines the number of shares subject to the awards by reference to the then-current market value of the Company's common stock.
             Performance Shares.     We use performance shares to promote long-term performance. We granted performance shares to our Named Executive Officers in February 2011 for a three-year performance period (the "2011 Performance Shares").

Table of Contents
             The following graph illustrates how the 2011 Performance Shares work:

             The Committee grants each award recipient a specified number of performance shares, which is considered the "Base Grant." The maximum award opportunity is 200% of the Base Grant. The 2011 Performance Shares have two distinct performance elements:

 50% of the Base Grant

             TSR is the measure of a company's stock price appreciation plus any dividends paid during the performance period. We believe using TSR strengthens the link between officer performance and shareholder return. Additionally, TSR is the most prevalent long-term incentive metric used among the Comparator Group. We anticipate that the common stock payout, if any, related to this performance element will be made in January 2014.

             The Company's "Average Performance" with respect to the performance metrics will be the average of the Company's percentile ranking for each of the following performance metrics during each of the three years of the performance period:
•
the J.D. Power Residential Survey (Western Region) percentile ranking of the Company relative to other participating companies;
•
the Edison Electric Institute quartile ranking (or percentile ranking, if available) associated with the Company's customer reliability results relative to other participating companies;
•
the Company's ranking for a customer-to-employee improvement ratio, based on data provided by SNL Financial ("SNL"), an independent third party data system relative to other companies reported in the SNL data;
- 32 -

Table of Contents
•
the Company's percentile ranking based on the OSHA rate (All Incident Injury Rate) relative to other companies reported in the EEI data;
•
the Company's percentile ranking based on nuclear generation capacity factors relative to other companies reported in the SNL data; and
•
the Company's percentile ranking based on coal generation capacity factors relative to other companies reported in the SNL data.
             These metrics are designed to add factors that will more effectively motivate performance while achieving desired goals of the Company. The metrics selected encompass performance inclusive of all departments and are direct indicators of key business performance success. The metrics can be readily benchmarked and will provide a clear barometer of top-tier performance excellence. We believe a focus on these performance metrics over a three-year period aligns long-term compensation with key operational goals, thereby enhancing overall Company performance. We anticipate that the common stock payout, if any, related to this performance element will be made in December 2014.
             The recipient must also remain employed with the Company throughout the performance period, unless the recipient retires. In the case of the recipient's retirement, the employee is deemed to have been employed through the end of the performance period, provided that, in the event the recipient is terminated for cause (regardless of the recipient's retirement or eligibility for retirement), the recipient shall not be deemed to have been employed through the end of the performance period and will forfeit the right to receive any payout.
             A participant who receives an award of performance shares is also entitled to additional shares of common stock equal to the amount of dividends that the participant would have received had the participant directly owned the shares from the date of grant to the date of payment, plus interest on such dividends at the rate of 5% per annum, compounded quarterly, divided by the fair market value of one share of stock on the date of the stock payout. This common stock is paid out when and only if the related common stock payout is made. The 2011 Performance Shares are not included in calculating pension benefits.
             We include the 2011 Performance Shares in the Summary Compensation Table in the column under "Stock Awards" and in the 2011 Grants of Plan-Based Awards table. They are also included in the Alternate 2011 Compensation Table.
             RSUs.     We granted RSUs to our Named Executive Officers in February 2011. RSUs are incentive awards that vest over a number of years if the award recipient remains employed by the Company or one of its subsidiaries. Each RSU represents the fair market value of one share of our common stock on the applicable vesting date. Since a portion of multiple RSU awards may vest each February, the Committee selected February 20 as the vesting date for all RSUs as an administrative convenience. The following graph illustrates how the 2011 RSUs work:

             The 2011 RSUs:
•
fully vest before the end of the regular vesting period if the participant retires (Mr. Robinson is treated as fully-vested by virtue of this provision because he qualifies for early retirement); however, the RSUs will be forfeited and the recipient will not be entitled
- 33 -

to receive any payment if the recipient's employment is terminated for cause regardless of the recipient's retirement or eligibility for retirement (unvested RSUs are forfeited if the participant's employment is terminated for any other reason);
•
are payable in stock or 50% cash and 50% stock, as the RSUs vest, at the election of the participant made shortly after the date of the initial grant, in an amount equal to the number of RSUs vesting multiplied by the closing price of a share of our common stock on the vesting date (in the case of a participant's retirement before the end of the vesting period other than for cause, as discussed above, the RSUs are payable on the dates and in the percentages specified in the vesting schedule even though fully-vested prior to those dates);
•
accrue dividend rights on the vested RSUs, equal to the amount of dividends that the participant would have received had the participant directly owned stock equal to the number of vested RSUs from the date of grant to the date of payment, plus interest at the rate of 5% per annum, compounded quarterly, with such amount paid either in stock or 50% stock and 50% cash; and
•
are not included in the calculation of pension benefits.
The 2011 RSUs are included in the Summary Compensation Table in the column under "Stock Awards" and in the 2011 Grants of Plan-Based Awards table. They are also included in the Alternate 2011 Compensation Table.
             Supplemental RSUs.     In February 2011, the Committee granted to the Company's officers a one-time award of a special class of RSUs that are payable solely in shares of common stock upon the recipient's retirement or other separation of employment. The Named Executive Officers received the following awards of these Supplemental RSUs:

             The Committee made these awards to recognize superior performance by the management team prior to 2011 and to provide a retention incentive. As such, the Committee considered the awards in the context of 2010 (and earlier) compensation, not 2011. Following is a discussion of the factors the Committee took into account in awarding the Supplemental RSUs. This discussion appeared in our Proxy Statement last year.
                           Creation of significant shareholder value.     Over the two-year period ended December 31, 2010, an aggregate of $1.7 billion of shareholder value was created for Pinnacle West shareholders.

  	 	  	 	  	 	Comparator Group	 	28.6%	 	  	 	 	 	  	
                          The Committee believed that the Company's management team contributed meaningfully to these superior results for shareholders. In addition to the financial returns, the Committee took into account the Company's achievements in 2010 that were set forth in our 2011 Proxy Statement, a number of which it believed set the foundation for continued improvement in the Company's operations and financial profile.
                           The Supplemental RSUs will assist the Company to retain management.     The Committee believed that the grants would encourage the retention of the executive team as well as other officers. The Company's officer group had experienced substantial change from 2007-2010 through a combination of retirements, promotions and external hires. A number of officers have substantial prior experience in the utility industry. The Committee understood that the market for executive talent in this industry is increasingly competitive, and that as a result the executive team is regularly exposed to a variety of other career opportunities. Accordingly, retention of experienced and qualified management will continue to be a priority for the Company. Equity grants such as the Supplemental RSUs are a commonly-used market technique for retention purposes.
                          Additionally, the Committee took into account that previous performance share grants awarded to a number of officers resulted in zero payouts in 2009 and 2010, due to the effect of substantial impairment charges necessitated by the Company's exit from real estate development and other unregulated businesses which began in 2009. This strategy had been successfully implemented through the liquidation of substantially all real estate operating assets and the sale of the Company's district cooling business in 2010. The liquidations and divestitures have generated more than $180 million of net cash proceeds and have de-risked the Company's financial profile, contributed to its improved liquidity and improved the Company's position in the credit markets. However, due to the resulting negative effect of the impairment charges on the previous performance share grants, the retention purpose that would have been served by the delivery of the original target value of these long-term incentives was not achieved. The Committee believed that the grants of Supplemental RSUs provided a retention incentive directly connected to the strong shareholder value created in the period when the previously-granted performance shares were ineffective to do so.
                          The grants should encourage the continued availability of key management to the Company and the consistent execution of business plans over the long-range horizon that typically characterizes the utility business. The Committee noted that since the Supplemental RSUs will result in the issuance of common stock, they would effectively increase management's personal stake in Pinnacle West and thereby further align management's interests with shareholder interests.
                           Description of the Supplemental RSUs.     In determining the structure of the Supplemental RSUs and the size of the grants awarded, the Committee consulted with the Consultant with respect to market practices.

Table of Contents
                          The Supplemental RSUs:
•
will each represent the right to receive one share of Pinnacle West common stock;
•
will vest in increments on the second, third and fourth anniversary dates of the grant date as follows, provided that the recipient remains employed by Pinnacle West or its subsidiaries on each such date:

			
Date
	 	Percentage of Each Grant
That Will Vest	
 	 	 	
February 15, 2013	 	50%	
February 15, 2014	 	25%	
February 15, 2015	 	25%	
•
will result in the issuance of shares of common stock to the recipient upon the recipient's retirement, death, disability or separation of employment from the Company;
•
will accrue notional dividends equal to the amount of dividends that a recipient would have received if the recipient had directly owned one share of Pinnacle West common stock for each Supplemental RSU held by the recipient from the grant date to each dividend payment date. The recipient will be credited with additional Supplemental RSUs on each dividend payment date equal to the amount of such dividends paid on such date divided by the fair market value of one share of common stock on such date. Such additional Supplemental RSUs will proportionally vest on the same remaining vesting schedule that applies to the original Supplemental RSUs and will result in the issuance of shares of common stock as provided above;
•
will be forfeited, to the extent that they have not vested, at any time when the recipient's employment is terminated;
•
will be excluded for purposes of the calculation of pension benefits; and
•
contain confidentiality protections that apply during employment and survive termination, and non-competition and employee non-solicitation provisions that survive for a period of one year following termination of employment.
                          Because the Supplemental RSUs were granted in 2011, they are included in the Summary Compensation Table and in the 2011 Grants of Plan-Based Awards table, even though they were not granted for 2011 performance. Because the Company considered the Supplemental RSU grants primarily in the context of performance prior to 2011 and retention purposes, such grants were not directly considered as part of the Committee's decision-making process in setting 2011 compensation. As such, they are not included in the Alternate 2011 Compensation Table.
Amendments to Existing Award Agreements.
             In developing the 2012 Plan, as to which we are seeking shareholder approval, the Committee considered the treatment of outstanding equity awards (i.e., those issued under the 2007 Plan) in the event of a change of control. Given the Company's increased emphasis on equity grants as part of the overall executive compensation program, the Committee has amended all outstanding performance share awards and RSU awards granted under the 2007 Plan to provide for treatment upon a change of control consistent with that provided under the 2012 Plan. The terms of the amendments, including an override provision which may be applied by the Board in the event of a change of control, are set forth under "Existing Equity Compensation Plans – Amendments to Existing Award Agreements."

 Benefits
             Pension Programs.     The Named Executive Officers participate in the Pinnacle West Retirement Plan ("Retirement Plan") and the Supplemental Excess Benefit Retirement Plan (the "Supplemental Plan"). We describe these plans in more detail under "Discussion of Pension Benefits." The Company believes that the pension programs are important recruitment and retention tools. In October 2010, the Committee reviewed the terms of the Supplemental Plan and decided to reduce the salary credits to a range of 8% to 18% as compared to the previous range of 12% to 28%, generally eliminate the retroactive feature and the 25-year service limit, and remove the joint and survivor subsidy. These changes went into effect for executive officers elected after January 1, 2011. The Committee changed the Supplemental Plan in order to better align it with existing market practices but still provide a competitive benefit.
             Deferred Compensation Programs.     The Company offers to its executive officers the ability, if the officer so chooses, to participate in a deferred compensation program. We describe our deferred compensation program in more detail under "Discussion of Nonqualified Deferred Compensation." We offer our deferred compensation program because the Committee believes that it is standard market practice to permit officers to defer all, or some portion, of their cash compensation. However, we generally consider the value in the deferred compensation plan to be the participant's own money and do not give this amount significant weight in making compensation decisions. In October 2011, the Company amended the plan to provide for a single interest rate and eliminate the five-year vesting requirement as discussed in more detail below under "Discussion of Nonqualified Deferred Compensation."
             Change of Control Agreements.     The Company maintains change of control arrangements ("Change of Control Agreements") for our officers, including the Named Executive Officers. Similar to our deferred compensation programs, Change of Control Agreements do not have a significant impact on compensation design. However, in setting annual incentives, we do consider that the change of control payment, if triggered, would be based on the average of these amounts for the prior four years. We discuss our Change of Control Agreements in more detail under "Potential Payments Upon Termination or Change of Control – Change of Control Agreements." Our Change of Control Agreements are "double trigger" agreements that provide severance benefits if, during a specified period following a change of control, the Company terminates an employee without "cause" or the employee terminates employment "for good reason." We believe that the possibility of strategic transactions or unsolicited offers creates job uncertainty for executives, and that the Change of Control Agreements are effective tools to provide incentives for executives to stay with the Company in light of these uncertainties. In addition, we believe that if the agreements are appropriately structured they do not deter takeovers or disadvantage shareholders. The Company's agreements are terminable on six months prior notice, prior to a change of control.
             In May 2009, in connection with a review of its executive compensation practices, the Company determined that, on a going-forward basis, it would no longer provide excise tax gross-up payments in new and materially amended Change of Control Agreements with its Named Executive Officers. In unusual circumstances where the Company believes that accommodations have to be made to recruit a new executive to the Company, limited reimbursement for taxes payable on change of control payments may be included in executives' contracts, but even in those circumstances, the excise tax gross-ups will be limited to payments triggered by both a change of control and termination of employment and will be subject to a three-year sunset provision.
             Perquisites.     We have had a long-standing policy of providing only limited perquisites to our executive officers. We describe our perquisites paid to each of the Named Executive Officers in footnote 4 to the Summary Compensation Table.

Table of Contents
              Taxation and Accounting Considerations Regarding Executive Compensation
             Publicly-traded corporations generally are not permitted to deduct, for federal income tax purposes, annual compensation in excess of $1 million paid to any of certain top executives, except to the extent the compensation qualifies as "performance-based" under rules set forth in the Internal Revenue Code (the "Code"). The Company does not use the deduction as a justification for awarding compensation below $1 million. To the extent the awards do exceed $1 million, the Company believes that it is in the shareholders' best interests to not only consider what components qualify for the deduction, but also preserve flexibility in designing a compensation program. For example, the RSUs described above do not qualify as performance-based compensation under the applicable tax provisions. The Committee and the Board may weigh the tax and accounting consequences of the total compensation program and the individual components of compensation when setting total compensation and determining the individual elements of an officer's compensation package. However, the Committee and the Board do not routinely apply the tax-deductibility rules to limit what they determine otherwise to be necessary and appropriate compensation awards.
              Stock Ownership and Retention Guidelines
             We believe that linking a significant portion of an officer's current and potential future net worth to the Company's success, as reflected in our stock price, helps to ensure that officers have a stake similar to that of our shareholders. Stock ownership guidelines also encourage the long-term management of the Company for the benefit of the shareholders.
             The Company's Stock Ownership and Retention Guidelines (the "Guidelines") are based on the officer's position and his or her base salary. The ownership requirements are shown in the table below in respect of the indicated officer position:

			
Officer 	 	Multiple of Base Salary 	
Chief Executive Officer	 	4 times Base Salary	
APS President and all Executive and Senior Vice Presidents	 	2 times Base Salary	
All Other Vice Presidents and Officers	 	1 times Base Salary	
             Each officer is expected to meet his or her ownership requirement within five years following the later of January 2010 or such officer's election (the "Phase-in Period"). In the event of (i) a promotion or a change in this Policy that would cause the officer to move into a higher multiple level or (ii) a base salary increase of more than 20% over the officer's previous base salary, an officer will have an additional three years to meet his or her applicable ownership requirement.
             The types of ownership arrangements counted toward the Guidelines are: common stock, whether held individually or jointly or in trust with or for the benefit of an immediate family member; shares issued upon the vesting of RSUs or the payout of performance shares; and unvested RSUs to the extent they will result in the issuance of common stock to the officer.
             Officers may not sell, pledge, margin, hedge, or otherwise grant an economic interest in ("Dispose") any shares of Company stock received by them pursuant to any of the Company's compensation or benefit programs (net of shares sold or surrendered to meet tax withholding or exercise requirements) until his or her ownership requirement has been met. Thereafter, the officer may Dispose of any shares to the extent such transaction would not cause the officer's share ownership to fall below his or her applicable requirement. The retention requirement applies both during and after the Phase-in Period. If the officer does not attain compliance with his or her ownership requirement by the end of the Phase-in Period, any subsequent grants of equity compensation to such officer will be payable solely in shares of stock until the ownership requirement is met. Under the Guidelines, the CEO may grant exceptions for hardship and other special circumstances.
             All of the Named Executive Officers are in compliance with the Guidelines.

2 The amount in this column represents the full grant date fair value for financial reporting purposes for the 2011 Performance Shares, RSUs and Supplemental RSUs. We describe the 2011 Performance Share, RSU and Supplemental RSU awards under "Executive Compensation Components – Long-Term Incentives" in the CD&A.
3 As required by SEC rules, the "Estimated Possible Payouts" represent the "threshold," "target," and "maximum" payouts the Named Executive Officers were eligible to receive under the 2011 Incentive Plans, although any awards are subject to the discretion of the Human Resources Committee. The actual awards paid to the Named Executive Officers under the 2011 Incentive Plans are disclosed in the "Non-Equity Incentive Plan Compensation" column of the Summary Compensation Table. With respect to Messrs. Hatfield, Edington and Falck under the 2011 Incentive Plans, the minimum amount each officer would have been eligible to receive was calculated based on APS earnings achieving the threshold amount, which would result in no payment with respect to the earnings portion of the 2011 Incentive Plans, and the business unit results at the lowest possible award. See "Executive Compensation Components – Annual Incentives" in the CD&A for additional information about the 2011 Incentive Plans.
4 This amount represents the 2011 Performance Shares described under "Executive Compensation Components – Long-Term Incentives – Performance Shares" in the CD&A. In accordance with SEC rules, we valued the awards based on the probable outcome at the time of the grant, which assumes the grant will be paid at 100% of the Base Grant and, in accordance with FASB ASC Topic 718, the closing stock price on the date of the grant. There were no forfeitures in 2011.
5 This amount represents the 2011 RSU awards described under "Executive Compensation Components – Long-Term Incentives – RSUs" in the CD&A. In accordance with FASB ASC Topic 718, we valued the RSUs using the number of RSUs awarded multiplied by the closing stock price on the date of the grant. There were no forfeitures in 2011.
6 This amount represents the Supplemental RSUs described under "Executive Compensation Components – Long-Term Incentives – Supplemental RSUs" in the CD&A. In accordance with FASB ASC Topic 718, we valued the Supplemental RSUs using the number awarded multiplied by the closing stock price on the date of the grant. There were no forfeitures in 2011.
7 This amount represents the dollar value of the 2011 Palo Verde Specific Compensation Opportunity described below. The actual amount paid to Mr. Edington is included in the "Non-Equity Incentive Plan Compensation" column of the Summary Compensation Table.
8 These amounts represent the payout opportunity under the outage incentive plans for the Refueling Outages. These incentive plans do not provide for a threshold or maximum payment.

 Narrative Disclosure to Summary Compensation Table and 2011 Grants of Plan-Based Awards Table
             See the CD&A for further information regarding the terms of awards reported in the Summary Compensation Table and the 2011 Grants of Plan-Based Awards table, and for discussions regarding the formulas or criteria to be applied in determining the amounts payable, vesting schedules, and the treatment of dividends.
             The Company does not have traditional employment agreements. We typically enter into offer letters with new executive officers. APS and Mr. Hatfield executed an offer letter dated June 17, 2008, pursuant to which Mr. Hatfield received the following: an annual base salary of $450,000; a hiring incentive of $200,000 that was paid to Mr. Hatfield in 2008, and $100,000 that was paid to Mr. Hatfield in 2009; participation in the officer annual incentive plan with a target payment of 50% and up to a maximum of 100% of annual base salary; an award of 1,400 performance shares which would have vested in 2009 (but did not pay out), an award of 2,000 performance shares which would have vested in 2010 (but did not pay out), an award of 3,400 performance shares which vested in part in 2011; an award of 2,500 RSUs that vested through February 20, 2011, and an award of 3,500 RSUs that vested through February 20, 2012; participation in the Supplemental Excess Benefit Retirement Plan and the Deferred Compensation Plan; relocation benefits; and a Change of Control Agreement similar to those provided to other executive officers.
             APS and Mr. Edington executed an offer letter, dated December 20, 2006, pursuant to which Mr. Edington received: an annual base salary of $600,000; a hiring bonus of $200,000 that was paid to Mr. Edington in 2007, plus subsequent bonuses of $100,000 that were paid to Mr. Edington in 2008 and 2009; participation in the annual incentive plan with a target of 50% and up to a maximum of 100% of annual base salary; an award of 10,000 retention units; annual grants of long-term performance awards pursuant to our long-term equity incentive programs if made by the Human Resources Committee, with his first grant of performance shares to be in the amount of $125,000; cash payments made by APS on the dates on which performance shares and stock options granted to Mr. Edington by his former employer would have vested, in an amount equal to the value of such stock grants; relocation benefits; and certain medical benefits, including lifetime medical coverage for Mr. Edington and his spouse. In addition, the offer letter provides that his total pension benefit (including the benefit due under the Company's qualified plan, general non-qualified plan, and the supplemental agreement discussed below) will be the greater of: (a) his total pension benefit if he had remained with his former employer for five more years, or (b) a pension benefit that will accrue at 10% per year, up to a maximum of 60%, which vested in January 2012. The percentage is applied to his final average wage (highest 3 years in the final 10 years of employment and includes both base salary and annual incentives) to determine his lifetime benefit. In addition, the retention units granted to him in January 2007 are also included in the calculation of pension benefits. If his employment is terminated for any reason other than voluntary resignation or termination for cause prior to meeting the vesting as indicated above, part (a) of this paragraph will become payable to Mr. Edington or his spouse. If part (b) of this paragraph applies, it will be paid to Mr. Edington in two forms: one-half of the benefit will be paid to him in a lump sum and the second half of the benefit will be paid to Mr. Edington in a 100% joint and survivor annuity.
             Mr. Edington's offer letter provides that he will participate in specific Palo Verde annual incentive opportunities. APS adopted the 2011 Palo Verde Specific Compensation Opportunity, which provided Mr. Edington the opportunity to receive up to $125,000 upon the achievement of the following Palo Verde operational and performance targets: successful evaluation by INPO at a defined minimum rating; the achievement of a site capacity factor equal to or greater than 90%; no substantive cross-cutting issues existing by the end of 2011; and no NRC colored findings by the end of 2011. As noted in the CD&A under "Executive Compensation Components – Annual Incentives," Mr. Edington received an award amount of $125,000 under this opportunity.

             In recognition of Mr. Edington's significant contributions to Palo Verde's improvement since he joined APS in early 2007 and his critical role in returning Palo Verde to long-term excellence, on July 18, 2008, APS and Mr. Edington entered into a letter agreement that provided as follows:
•
Mr. Edington's base salary was increased to $800,000, effective June 1, 2008.
•
APS entered into a separate deferred compensation arrangement with Mr. Edington, pursuant to which APS credited Mr. Edington's deferred compensation account with $1 million, effective as of July 15, 2008. APS increased this account balance by an additional $1 million on June 1 of each year beginning June 1, 2009, until the account reached $4 million on June 1, 2011. The account will vest on June 1, 2012 if Mr. Edington remains with APS and will be payable before that date upon Mr. Edington's death, disability, or involuntary termination.
•
Effective July 15, 2008, APS established for Mr. Edington a life insurance benefit of $3 million that decreased by $1 million on June 1 of each year, beginning June 1, 2009, until the life insurance benefit terminated on June 1, 2011.
             On December 26, 2008, APS and Mr. Edington entered into a supplemental agreement further defining Mr. Edington's pension benefits as set forth in the December 20, 2006 letter, and the deferred compensation arrangement as set forth in the July 18, 2008 letter.
             Pinnacle West and Mr. Falck executed an offer letter in May 2009, pursuant to which Mr. Falck received: a starting annual base salary of $450,000; hiring incentive payments of $200,000 and $150,000 that were paid in 2009 and 2010, respectively; participation in the officer annual incentive plan with a target payment of 50% and up to a maximum of 100% of annual base salary; an award of 8,580 performance shares, which vested in part in March 2011 and in part in December 2011 and an award of 13,000 performance shares, which will vest in 2012 if the performance criteria are met (the performance share grants were based 50% upon an earnings per share metric and 50% upon the six performance metrics specified in the CD&A under "Executive Compensation Components – Long-Term Incentives – Performance Shares"); an award of 9,750 RSUs that vested through February 20, 2012 and an award of 13,000 RSUs that will vest through February 20, 2013; participation in the Supplemental Excess Benefit Retirement Plan and the Deferred Compensation Plan; a special discretionary credit award, which is described under "Discussion of Nonqualified Deferred Compensation;" and a Change of Control Agreement similar to those provided to other officers but modified to include a three-year sunset on the excise tax gross-up provisions; and relocation benefits.

5 This amount represents the remaining RSUs awarded in 2009. The 2009 RSUs vest and are released in 25% increments beginning on February 20, 2010, so that they will be fully vested on February 20, 2013. Dividend rights (and interest thereon) are paid in cash for this award.
6 This amount represents the remaining RSUs awarded in 2008. The 2008 RSUs vest and are released in 25% increments beginning on February 20, 2009, so that they were fully vested on February 17, 2012. Dividend rights (and interest thereon) are paid in cash for this award.
7 This amount represents: (i) the 2011 Performance Shares – SEC rules require us to assume a number of shares equal to the target (100% of Base Grant) payout level of the performance shares for the 2011 Performance Shares, although the actual number of shares awarded, if any, will not be determined until after the end of the performance period, which ends on December 31, 2013; and (ii) accrued dividend rights (and interest thereon) that will be paid in stock as follows: Mr. Brandt – 1,195; Mr. Hatfield – 199; Mr. Edington – 199; Mr. Falck – 279; and Mr. Robinson – 426.

1 The amount in this column consists of: (i) RSUs that were granted to Messrs. Brandt, Hatfield, Edington and Falck in January 2010 that vested and were released in part on February 18, 2011 as follows: Mr. Brandt – 7,825; Mr. Hatfield – 1,066; Mr. Edington – 1,665; and Mr. Falck – 2,331; dividend rights (and interest thereon) payable in stock earned on RSUs granted in January 2010 and released on February 18, 2011 as follows: Mr. Brandt – 253; Mr. Hatfield – 69; Mr. Edington – 108; Mr. Falck – 151; and Mr. Robinson – 95; RSUs that were granted to Messrs. Brandt, Hatfield and Edington in February 2009 and Mr. Falck in July 2009 that vested and were released in part on February 18, 2011 as follows: Mr. Brandt – 7,438; Mr. Hatfield – 875; Mr. Edington – 2,000; and Mr. Falck – 3,250; RSUs that were granted to Messrs. Brandt and Edington in February 2008, Mr. Hatfield in October 2008 and Mr. Falck in July 2009 and that vested and were released, in part, on February 18, 2011 as follows: Mr. Brandt – 3,313; Mr. Hatfield – 1,000; Mr. Edington – 2,000; and Mr. Falck – 3,250; RSUs that were granted to Messrs. Brandt and Edington in February 2007 and to Mr. Hatfield in October 2008 and that vested and were released, in part, on February 18, 2011 as follows: Mr. Brandt – 2,500; Mr. Hatfield – 1,000; and Mr. Edington – 1,525; 12,828 RSUs that were granted (but were not released) to Mr. Robinson in February 2011 and 617 dividend rights (and interest thereon) payable in stock accrued in connection with Mr. Robinson's 2010 and 2011 grants; and (ii) 6,074 performance shares granted to Mr. Falck in July 2009 that vested in 2010 but were not released until December 2011 when the Company was able to determine whether, and the extent to which, the performance metrics were met.
2 The values realized for the RSUs and the performance shares are calculated by multiplying the number of shares of stock or units released by the market value of the common stock on the release date, which: (i) for the RSUs for Messrs. Brandt, Edington, Falck and Hatfield was $41.88; (ii) for the RSUs for Mr. Robinson was $41.71; and (iii) for Mr. Falck's 2008 performance shares was $47.80. Mr. Robinson is treated as fully vested in the 2011 RSUs at the time of the grant because under the grant, an individual becomes fully vested at the time the individual becomes eligible for retirement under the Company's retirement plan. Although fully vested, the awards will be released to Mr. Robinson in four equal, annual installments beginning on February 20, 2012. The value of the dividend rights (and interest thereon) payable in stock accrued for Mr. Robinson are calculated by multiplying the number of shares of stock by the year-end closing price of $48.18.

 Discussion of Pension Benefits
             Retirement Plan and Supplemental Plan.     The Company's Retirement Plan is a tax-qualified, non-contributory retirement plan for salaried and hourly employees. The Supplemental Plan provides retirement benefits for key salaried employees in addition to those provided under the Retirement Plan. The Supplemental Plan pays only the difference between the total benefit payable under the Supplemental Plan and the benefit payable under the Retirement Plan. As a result, an executive who participates in the Supplemental Plan does not receive duplicative benefits.
             Prior to April 1, 2003, benefits under the Retirement Plan and the Supplemental Plan (the "Traditional Formula Benefit") accrued in accordance with a traditional retirement plan formula based on average annual compensation and years of service (the "Traditional Formula"). Effective April 1, 2003, the Company changed the benefit accrual formula for both the Retirement Plan and the Supplemental Plan (the "Account Balance Benefit") to a retirement account balance formula (the "Account Balance Formula"). As part of the modification, all then current participants were able to elect to either (a) continue to earn benefits calculated under the Traditional Formula, or (b) earn benefits calculated (i) under the Traditional Formula for service through March 31, 2003, and (ii) under the Account Balance Formula for service after that date. Messrs. Brandt's and Robinson's benefits are calculated under the combined Traditional Formula/Account Balance Formula. Messrs. Hatfield's and Falck's benefits are calculated under the Account Balance Formula. Mr. Edington's benefits under the Retirement Plan are calculated under the Account Balance Formula. His benefits under the Supplemental Plan are calculated in accordance with his employment agreement with the Company, which is described in the narrative disclosure accompanying the Summary Compensation Table and the 2011 Grants of Plan-Based Awards table.
             Under the Traditional Formula of the Supplemental Plan, a participant's monthly benefit for life beginning at normal retirement age (age 65 or age 60 with 20 years of service) is equal to the following:
•
3% of the participant's average monthly compensation multiplied by the participant's first 10 years of service, plus
•
2% of the participant's average monthly compensation multiplied by the participant's next 15 years of service, minus
•
benefits payable under the Retirement Plan.
             A participant's Traditional Formula Benefit under the Retirement Plan is a monthly benefit for life beginning at normal retirement age and is equal to the participant's average monthly compensation multiplied by 1.65% for the first 33 years of service, plus 1% of average monthly compensation for each year of service credited in excess of 33 years. A participant's Traditional Formula Benefit begins when the participant reaches age 65 with 5 years of service or age 60 with 33 years of service. The maximum Traditional Formula Benefit a participant may receive under both the Retirement Plan and the Supplemental Plan is a monthly benefit of 60% of the participant's average monthly compensation.
             Under both the Supplemental Plan and the Retirement Plan, a participant may elect to begin receiving the Traditional Formula Benefit after attaining early retirement age, which is defined as age 55 with 10 years of service. The Traditional Formula Benefit of an individual who makes this election is reduced to reflect the early commencement of benefits; the reduction equals 3% per year for each year for which the individual receives benefits prior to normal retirement. Mr. Robinson currently qualifies for early retirement under the Retirement Plan and the Supplemental Plan. He does not currently qualify for normal retirement under the Retirement Plan or the Supplemental Plan. Messrs. Brandt, Hatfield, Edington and Falck do not currently qualify for early or normal retirement under either the Supplemental Plan or the Retirement Plan.

Table of Contents
             Under the Account Balance Formula, a notional account is established for each eligible participant and benefits are generally payable at termination of employment. The Company credits monthly amounts to a participant's account.
             Under the Supplemental Plan, Company credits are based on the following formula:

									
 	
  	 	Age at End of Plan Year
  
    	 	  	 	Percent of Monthly
Compensation Contribution
Rate
(%)	 	  	
  	 	Less than 35	 	  	 	12	 	  	
  	 	35-39	 	  	 	14	 	  	
  	 	40-44	 	  	 	16	 	  	
  	 	45-49	 	  	 	20	 	  	
  	 	50-54	 	  	 	24	 	  	
  	 	55 and over	 	  	 	28	 	  	
             Company credits under the Supplemental Plan stop at the end of the year in which a participant attains 25 years of service (the "25-Year Cap").
             Under the Retirement Plan, Company credits are based on the following formula:

									
 	
  	 	Age Plus Whole Years of
Service at End of Plan Year
    	 	  	 	Percent of Monthly
Compensation Contribution
Rate
(%)	 	  	
  	 	Less than 40	 	  	 	4	 	  	
  	 	40-49	 	  	 	5	 	  	
  	 	50-59	 	  	 	6	 	  	
  	 	60-69	 	  	 	7	 	  	
  	 	70-79	 	  	 	9	 	  	
  	 	80 and over	 	  	 	11	 	  	
             In addition, participants in the Retirement Plan on December 31, 2002 are eligible for up to 10 years of transition credits based on age and years of service (with the maximum transition credit being equal to 2.75% of average monthly compensation).
             For purposes of calculating the Traditional Formula Benefit and the Account Balance Benefit under the Retirement Plan, compensation consists solely of base salary up to $245,000, including any employee contributions under the Company's 401(k) plan, flexible benefits plan and qualified transportation arrangement under Section 132(f) of the Code. Amounts voluntarily deferred under other deferred compensation plans, bonuses and incentive pay are not taken into account under the Retirement Plan. The Supplemental Plan takes these amounts into account (with certain exceptions) plus base salary beyond the $245,000 limit. In addition, the retention units granted in December 2006 and January 2007 are included in compensation under the Supplemental Plan.
             For purposes of the Traditional Formula under the Retirement Plan, the average monthly compensation is the average of the highest 36 consecutive months of compensation in the final 10 years of employment; under the Supplemental Plan, the average monthly compensation is the average of the highest 36 consecutive months of compensation during employment. For purposes of the Account
- 51 -

Table of Contents
Balance Formula, contributions are based on the participant's then current monthly compensation calculated as described above.
             A participant's years of service begin accruing on the date of employment. However, benefits do not vest until the completion of three years of service. The Company has from time to time granted key executives additional years of service and/or additional benefits as a percentage of average monthly compensation under the Supplemental Plan when necessary and appropriate to recruit and retain, and in limited situations, reward such executives. All such arrangements are pursuant to written agreements. Mr. Edington's employment agreement provides him with a benefit equal to the greater of (a) an amount equal to his total pension benefit if he had stayed at his prior employer for five more years, or (b) a pension benefit which will accrue at 10% of his final average pay per year of service, up to a maximum of 60% of his final average pay, which vested in January 2012.
             Under both the Retirement Plan and the Supplemental Plan, benefits are generally payable, as the participant elects, in the form of a level annuity, with or without survivorship, or a lump sum. However, Traditional Formula Benefits generally are not available as a lump sum, but are paid in the form of an annuity. Optional benefit forms are of relative actuarial value under the Retirement Plan. Under the Supplemental Plan, the 50% joint and survivor benefit form is fully subsidized, and the other benefit forms are partially subsidized. The Supplemental Plan offers an optional five-year certain form of payment (payable in 60 monthly installments).
             Effective January 1, 2011, the Supplemental Plan was amended to reduce the Company credits for individuals who become participants on or after January 1, 2011 to the levels listed in the following table:

									
 	
  	 	Age at End of Plan Year
  
    	 	  	 	Percent of Monthly
Compensation Contribution
Rate
(%)	 	  	
  	 	Less than 35	 	  	 	  8	 	  	
  	 	35-39	 	  	 	  9	 	  	
  	 	40-44	 	  	 	10	 	  	
  	 	45-49	 	  	 	12	 	  	
  	 	50-54	 	  	 	15	 	  	
  	 	55 and over	 	  	 	18	 	  	
             In addition, individuals who become participants in the Supplemental Plan on or after January 1, 2011 are no longer entitled to receive a fully subsidized 50% joint and survivor annuity form of benefit, but the 25-Year Cap has been eliminated. Prior to the amendment, participants who were promoted to officer status were entitled to retroactive treatment as an officer for their entire period of employment. This feature has been eliminated for individuals promoted to officer status on or after January 1, 2011.
             Benefits under the Retirement Plan are paid from a tax-exempt trust. Benefits under the Supplemental Plan are paid from the general assets of the Company.

1 The amount of the executive contribution is solely from the voluntary deferral by the executive of the executive's designated compensation and does not include any separate Company contribution. These deferred amounts are included in the "Salary" and "Non-Equity Incentive Plan Compensation" columns in the Summary Compensation Table.
2 A portion of the amounts reported in this column is also reported as compensation in the Summary Compensation Table, including, Mr. Brandt – $44,956; Mr. Hatfield – $2,143; Mr. Edington – $49,217; Mr. Falck – $16,025; and Mr. Robinson – $19,662. See clause (ii) of the first sentence of footnote 3 to the Summary Compensation Table.
3 The historical contributions of each Named Executive Officer to his aggregate balance at December 31, 2011, including "market rate" interest (as defined by the SEC) from the date of each contribution, is as follows: Mr. Brandt – $1,026,626; Mr. Hatfield – $51,880; Mr. Edington – $1,178,702; and Mr. Robinson – $454,158. Of the totals in this column, the following amounts have previously been reported in the Summary Compensation Table in this Proxy Statement or in the Company's prior Proxy Statements: Mr. Brandt – $940,093; Mr. Hatfield – $51,331; Mr. Edington – $1,152,786; Mr. Falck – $31,409; and Mr. Robinson – $259,506.
4 Mr. Edington became fully vested under the 2005 Plan on December 31, 2011. He will not be fully vested in his deferred compensation pursuant to his agreement until June 1, 2012. We describe the agreement we have with Mr. Edington regarding his deferred compensation in the narrative disclosure accompanying the Summary Compensation Table and the 2011 Grants of Plan-Based Awards table and show the amount payable in the event of termination under "Potential Payments Upon Termination or Change of Control."
5 Pursuant to Mr. Falck's offer letter, described under "Discussion of Nonqualified Deferred Compensation – DCP and 2005 Plan" below, the Company made a $350,000 credit award to Mr. Falck in 2009. The first $250,000 and interest accrued will vest on July 29, 2014 and the remaining $100,000 and interest accrued will vest on July 29, 2016 as long as he is employed by the Company on those dates.

 Discussion of Nonqualified Deferred Compensation
             DCP and 2005 Plan.     Effective January 1, 1992, the Company established The Pinnacle West Capital Corporation, Arizona Public Service Company, SunCor Development Company, and El Dorado Investment Company Deferred Compensation Plan (the "DCP"). Under the DCP, a participant who was an employee was allowed to defer up to 50% of annual base salary and up to 100% of year-end bonus, which would include awards under regular annual incentive plans, but not special incentive payments. A participant who is a member of the Board is allowed to defer up to 100% of the annual cash fees payable to the participant. Amounts deferred by participants are credited with interest at various rates in substantially the same manner as interest is credited pursuant to the 2005 Plan, as described below. Distributions may be made (i) within 30 days after the fifth year an amount was deferred, (ii) on account of an unforeseen emergency, (iii) on account of retirement after attaining age 65 with five years of service or after attaining age 55 with 10 years of service ("Retirement Benefit"), (iv) on account of termination prior to retirement ("Termination Benefit"), (v) on account of disability, or (vi) on account of death before termination of employment.
             The Retirement Benefit and Termination Benefit are payable in a lump sum or in 5, 10, or 15 equal annual installments, as elected by the participant. Other benefits are generally paid in a lump sum. The method of crediting interest on lump sum and installment payments under the DCP is substantially the same as the method used in the 2005 Plan, as described below.
             On December 15, 2004, the Board authorized the adoption of a new nonqualified deferred compensation plan for post-2004 deferrals (the "2005 Plan"). No future deferrals will be permitted under the DCP. The 2005 Plan, effective as of January 1, 2005, is based in large part on the DCP as described above. The 2005 Plan was adopted to comply with the requirements of Section 409A of the Internal Revenue Code.
             Under the 2005 Plan, a participant who is an employee is allowed to defer up to 50% of the participant's base salary and up to 100% of the participant's bonus, including regular awards under annual incentive plans, but not special awards. A participant who is a member of the Board is allowed to defer up to 100% of the annual cash fees payable to the participant. Amounts deferred by participants are credited with interest at various rates, as described below. Deferral elections of base salary and director's fees must be made prior to the calendar year in which such base salary or director's fees will be paid. A deferral election with respect to a bonus must be made before the first day of the calendar year in which the bonus is earned. When making a deferral election, a participant also makes an election regarding the time and form of the participant's distributions from the 2005 Plan. Distributions from the 2005 Plan must be made in accordance with Section 409A of the Internal Revenue Code. Distributions are made (i) in January of the fifth year following the year in which an amount was deferred, (ii) on account of an unforeseeable financial emergency, (iii) on the later of termination of employment or attainment of age 55, or (iv) on account of death before termination of employment.

Table of Contents
             In the event of termination of employment, attainment of age 55 or death, the benefit is payable in a lump sum or in 5, 10 or 15 equal annual installments, as elected by the participant. Benefits in the other circumstances are generally paid in a lump sum.
             Up until October 2011, the Company used two different interest rates to determine the amount of the participant's benefit under the 2005 Plan. The first was the "Base Rate," which, for any calendar year, was the 10-year U.S. Treasury Note rate published on the last business day of the first week of October preceding such calendar year. The second was the "Plan Rate," which was the sum of the "Base Rate" and the "Supplemental Rate." The plan committee appointed by the Board determined the "Supplemental Rate." From January 2011 until October 2011, the "Base Rate" was 2.54% and the "Supplemental Rate" was 4.96%.
             As a general rule, the interest rate used to determine the amount of the benefit payable in a lump sum is as follows:

			
Years of Plan Participation 	 	Interest Rate 	
Less than five (and termination occurs other than due to retirement and more than six months prior to change of control)	 	Base Rate	

All other situations	
 	
Plan Rate	
             The interest rate used to determine the amount of the benefit payable in installments is a fixed rate equal to the average Plan Rate for the plan year in which the participant becomes eligible to receive the benefit and the four prior plan years. If the participant has fewer than five plan years of participation and terminates employment for reasons other than retirement, the interest rate used to calculate installments is a fixed rate equal to the average Base Rate for the plan years of participation. If the participant's installment payout begins on or after the date that is six months prior to a change of control of the Company, the Company is required to pay benefits using an average of the Plan Rate for the plan years of participation.
             In October 2011, the Company amended the 2005 Plan to provide for a single rate of interest that will be determined by the plan committee, but which rate shall in no event be less than the rate of interest equal to the 10-year U.S. Treasury Note rate as published on the last business day of the first week of October preceding a plan year. The amendment also removed the five-year vesting provision. The plan committee set the rate at 7.5%, which rate will be in effect until the end of 2012.
             Effective January 1, 2009, the Company amended the 2005 Plan to permit the Company, in its discretion, to award discretionary credits to participants. Discretionary credits generally will be paid at the time and in the form provided in the written award agreement.
             The Company agreed in Mr. Falck's offer letter to make a $350,000 discretionary credit award to Mr. Falck in 2009, pursuant to the 2005 Plan. The first $250,000 will vest on July 29, 2014 and the remaining $100,000 will vest on July 29, 2016. The $350,000 discretionary credit award earns interest in accordance with the 2005 Plan. The full amount of the discretionary credit award vests and becomes payable if the Company terminates Mr. Falck's employment without cause within two years following a change of control, or in the event of his death. If Mr. Falck terminates employment, for any reason other than those discussed above, prior to July 29, 2014, he forfeits the entire discretionary credit award; if such termination occurs between July 30, 2014 and July 29, 2016, Mr. Falck forfeits $100,000.
             Participation in both the DCP and the 2005 Plan is limited to officers, the Company's senior management group and directors of the Company and participating affiliates. The Company's obligations under the DCP and the 2005 Plan are unfunded (except in the limited change of control circumstance discussed below) and unsecured.

             Other Deferred Compensation Arrangements.     The Company agreed in Mr. Edington's letter agreement to award him deferred compensation in addition to any deferred compensation pursuant to the 2005 Plan. This award is described in the narrative disclosure accompanying the Summary Compensation Table and the 2011 Grants of Plan-Based Awards table and under "Potential Payments Upon Termination or Change of Control."

 Potential Payments Upon Termination or Change of Control
             This section describes the potential payments that each of the Named Executive Officers could receive following termination of employment, including through death, disability, retirement, resignation, involuntary termination (with and without cause) or a change of control of the Company (each, a "Termination Event"). We describe plans, agreements, or arrangements under which each Named Executive Officer could receive payments following a Termination Event, excluding those that do not discriminate in favor of our executive officers and that are available generally to all salaried employees and awards that are already vested ("Termination Plans"). The payments to the Named Executive Officers under the various Termination Event scenarios described in this section are not intended to affect the Company's obligations to the Named Executive Officers. Those obligations are subject to, and qualified by, the contracts or arrangements giving rise to such obligations. Unless we note otherwise, the discussion below assumes that any Termination Event took place on December 30, 2011 (the last business day of the fiscal year 2011) for each Named Executive Officer.
             The Company does not have a severance plan that covers the Named Executive Officers. We also do not have traditional severance agreements or arrangements with our Named Executive Officers. We do have Change of Control Agreements which are discussed under "Change of Control Agreements."
             In addition to the termination payments set forth below, the Named Executive Officers would also receive a full distribution under the 2005 Plan (except in the case of Mr. Falck's DCP discretionary credits, which are discussed separately below) and pension benefits. Amounts payable to Messrs. Brandt, Hatfield, Edington and Robinson under the 2005 Plan are set forth in the 2011 Nonqualified Deferred Compensation table, which also shows which part of the payment was interest paid by the Company and which part is the executive's contribution.
             With respect to pension benefits, the amounts that each of the Named Executive Officers would receive under the Supplemental Plan in the event of a Termination Event are set forth in the 2011 Pension Benefits table; however, assuming that the Named Executive Officer had died on December 30, 2011, the amounts payable under the Supplemental Plan (and in the case of Mr. Edington, under the Supplemental Plan and his employment agreement), would have been as follows: Mr. Brandt – $4,121,177; Mr. Hatfield – $597,326; Mr. Edington – $9,422,937; Mr. Falck – $442,109; and Mr. Robinson – $7,967,177. These amounts are based on the following assumptions: (i) the Traditional Formula Benefit is paid in the form of a monthly annuity to the Named Executive Officer's spouse for life following his death and benefit payments commence immediately; (ii) the Account Balance Benefit is paid in the form of an immediate lump sum to his spouse; and (iii) in the case of Mr. Edington, 50% of the benefit is paid as an annuity and 50% of the benefit is paid as a lump sum to his spouse as provided in his employment agreement. With respect to Mr. Robinson, he would have received $8,110,478 in the event of a Termination Event other than death, disability or change of control due to his qualification for early retirement on December 30, 2011 – this amount is based on the assumption that the benefit would be payable as a monthly annuity beginning on January 1, 2012.
             Mr. Falck and Mr. Edington have deferred compensation agreements with the Company that would trigger a payment in connection with certain Termination Events, which are identified below. The agreements are discussed in the narrative disclosure accompanying the Summary Compensation Table and the 2011 Grants of Plan-Based Awards table.

1 Mr. Robinson is entitled to receive stock payouts, if any, under the 2009, 2010 and 2011 performance share awards if the Company attains specified performance criteria for the three-year periods ended December 31, 2011, 2012 and 2013, respectively, because under the 2009, 2010 and 2011 award agreements, an employee is deemed to have been employed through the performance period if the employee retires after reaching the age of retirement and attaining the requisite years of service. Assuming a maximum payout level for the 2009 and 2010 performance share awards, and a target payout level for the 2011 Performance Shares (see footnotes 7-9 to the 2011 Outstanding Equity Awards at Fiscal Year-End table), Mr. Robinson would receive the following stock payouts in 2012, 2013 and 2014 (using the closing market price on December 30, 2011 of $48.18): $1,106,499 for 2012; $1,324,898 for 2013 and $713,005 for 2014. However, Mr. Robinson is not entitled to a payout under the 2011 Performance Shares in the event he is terminated for cause.
2 Mr. Robinson is treated as fully-vested under the outstanding RSUs awards because he qualifies for early retirement. If Mr. Robinson had retired effective December 31, 2011, he would have been entitled to receive $550,230 on February 17, 2012 (using the closing market price on December 30, 2011 of $48.18), and would be entitled to receive the following amounts on the 20th day of February 2013, 2014, and 2015 (using the same closing market price): $522,484 for 2013; $347,256 for 2014; and $184,131 for 2015. However, Mr. Robinson is not entitled to payout under the RSUs granted in 2011 in the event he is terminated for cause.
             Change of Control Agreements.     The Company has entered into identical Change of Control Agreements with each of its executive officers, including each of the Named Executive Officers. The Company intends that these agreements provide stability in its key management in the event the Company experiences a change of control. The agreements contain a "double-trigger" that provides for certain payments if, during the two-year period following a change of control of the Company (the "first trigger"), the Company involuntarily terminates the officer's employment or the executive terminates his or her own employment following a significant and detrimental change in the executive's employment (the "second trigger"). In case of an officer's retirement, death or disability, no payments are made under the officer's Change of Control Agreement, except for the payment of accrued benefits; however, if the officer dies following the officer's receipt of a second trigger termination notice, the officer's estate will receive the change of control payments the officer would have received if the officer had survived. Pursuant to the Change of Control Agreement, each of the Named Executive Officers is obligated to hold in confidence any and all information in his possession as a result of his employment, during and after the Named Executive Officer's employment with the Company is terminated.
             The termination payment, if required, is an amount equal to 2.99 times the sum of the executive's annual salary at the change of control as increased to the date of termination plus the annual bonus (including incentive plan payments), as determined by an average over the last four years preceding termination. In addition, the executive is entitled to continued medical, dental, and group life insurance benefits at a shared cost until the end of the second year following the calendar year of termination. The termination is treated as a normal termination under the Company's stock option and

benefit plans entitling the executive to exercise outstanding options within three months after termination and causing restrictions on restricted stock to lapse. Outplacement services are also provided. If the limitations described in Section 280G of the Internal Revenue Code are exceeded, the Company will not be able to deduct a portion of its payments. In addition, if these limitations are exceeded, Section 4999 of the Internal Revenue Code imposes an excise tax on all or part of the total payments. The agreement provides for an additional gross-up payment equal to the excise tax (plus any penalties and interest) imposed on or with respect to the total payments.
             In May 2009, the Company determined that, on a going forward basis, it will no longer provide excise tax gross-up payments in new and materially amended agreements with its Named Executive Officers. In unusual circumstances where the Company believes that accommodations have to be made to recruit a new executive to the Company, limited reimbursement for taxes payable may be included in an executive's contract; but even in those circumstances, the excise tax gross-ups will be subject to a three-year sunset provision.
             A change of control under the Change of Control Agreement includes: (1) an unrelated third party's acquisition of 20% or more of the Company's or APS's voting stock; (2) a merger or consolidation where either the Company or APS combines with any other corporation such that the Company's or APS's outstanding voting stock immediately prior to merger or consolidation represents less than 60% of the voting stock of the Company or APS immediately after the merger or consolidation, but excluding a merger or consolidation effected to implement a recapitalization in which no unrelated third party acquires more than 20% of the voting stock of the Company or APS; (3) a sale, transfer, or other disposition of all or substantially all of the assets of the Company or APS to an unrelated third party; or (4) the case where the composition of either the Board of the Company or of APS changes such that the members of the Board of the Company (the "Company Incumbent Board") or of APS (the "APS Incumbent Board"), as of July 31, 2007 (and with respect to Mr. Hatfield and Mr. Falck as of July 31, 2008) no longer comprises at least two-thirds of the Company's or APS's Board of Directors. For purposes of this later provision, a person elected to either Board, is treated as a member of the Company Incumbent Board or APS Incumbent Board if his or her nomination or election by shareholders was approved by a two-thirds vote of the members then comprising the Company Incumbent Board or APS Incumbent Board, and it does not include anyone who became a director in an actual or threatened election contest relating to the election of directors.
             Each of the agreements terminates on December 31 of each year upon six months advance notice by the Company to the executive officer; if the six months advance notice is not given, the agreements will continue for successive one-year periods until the notice is given. The Company is required to deposit into a trust sufficient funds to pay obligations under the DCP, 2005 Plan and the Supplemental Plan in the case of an actual or potential change of control.

1 In accordance with FASB ASC Topic 718, this amount reflects the aggregate grant date fair value of the stock award. On July 1, 2011, all of the directors at the time received a grant of either common stock or RSUs, based on an election previously delivered to the Company. All directors received common stock except for Mr. Gallagher, Drs. Herberger and Klein, and Ms. Munro, who each received RSUs. Under the terms of the RSUs, Mr. Gallagher and Dr. Herberger will receive 50% of the RSUs in cash and 50% of the RSUs in common stock and Dr. Klein and Ms. Munro will receive one share of common stock for each RSU, in all cases, on the last business day of the month following the month in which they separate from service on the Board. The number of shares of common stock or RSUs granted was 1,699 and the grant date fair value of each share of common stock or RSU is $45.10, which was the closing stock price on July 1, 2011. The stock grants were not subject to forfeiture.
2 The Company does not have a pension plan for directors. The amount in this column consists solely of the above-market portion of annual interest accrued under a deferred compensation plan pursuant to which directors may defer all or a portion of their Board fees. See the discussion of the rates of interest applicable to the deferred compensation program under "Discussion of Nonqualified Deferred Compensation."
3 This amount represents an insurance premium for a business travel and accident policy that covers all directors and officers.
4 Mr. Brandt is a Named Executive Officer and his compensation is set forth in the Summary Compensation Table. Mr. Brandt did not receive any additional compensation during 2011 in connection with his service as a director.

 Discussion of Directors' Compensation
             The Human Resources Committee makes recommendations to the Board for compensation, equity participation, and other benefits for directors. The Human Resources Committee and the Board generally review director compensation every two years.
             The director compensation program consists of the following components:

									
 	 	 	 	 	 	 	
   	 	 Compensation Component
    	 	  	 	Amount
    	 	  	
    	 	 Annual Retainer	 	  	 	$80,000	 	  	
   	 	 Audit Committee, Human Resources Committee, Finance Committee, and Nuclear and Operating Committee Chair Annual Retainer	 	  	 	$12,500	 	  	
    	 	 Lead Director Annual Retainer (Lead Director serves as Chair of Corporate Governance Committee for no additional compensation)	 	  	 	$15,000	 	  	
   	 	 Equity Grant on July 1	 	  	 	Shares equal to approximately $75,000	 	  	
             Directors have an option to either receive the stock grant on July 1 or defer the receipt until a later date. A director who elects to defer the receipt of stock will receive RSUs in lieu of the stock grant. A director who elects to receive RSUs may elect to receive payment for the RSUs in either (1) stock or (2) 50% in stock or 50% in cash. The director may elect to receive these payments either (1) as of the last business day of the month following the month in which the director separates from service on the Board, or (2) as of a date specified by the director, which date must be after December 31 of the year in which the grant was received. The RSUs accrue dividend rights equal to the amount of dividends the director would have received if the director had directly owned one share of our common stock for each RSU held plus interest at the rate of 5% per annum, compounded quarterly. The manner of payment for the dividends and interest will be based on the director's election for payment of the RSUs.
             Only non-management directors are compensated for Board service. Company directors also serve as APS directors for no additional compensation. The Company reimburses Board members for expenses associated with Board meetings and director education programs.
             A comparison against the compensation programs of our current comparator group is generally performed every two years, and in January 2012, the Board approved increasing the annual equity grant to $90,000 and the Lead Director annual retainer to $20,000. These adjustments moved the equity grant to the median and the Lead Director annual retainer to the median/75 th  percentile of our comparator group. These changes will go into effect for the 2012-2013 term of the Board beginning in May 2012.

 Director Stock Ownership Guidelines
             The Company believes that directors should have meaningful financial stakes in the Company to align their personal financial interests with those of the Company's shareholders.
             In January 2010, the Board adopted a revised stock ownership policy for non-management directors. Each director is required to hold or control Company common stock or RSUs with a value of at least three times the annual cash retainer fee paid to directors. Directors will have until the later of January 2013 or three years following the date they become a director (the "Director Ramp-Up Period") to reach the required ownership level. The Corporate Governance Committee has the
- 61 -

discretion to grant a temporary waiver of the ownership policy to a director due to financial hardship or other good cause shown. All of the directors are in compliance with the Director Stock Ownership Guidelines.

 PROPOSAL 2 – APPROVAL OF THE PINNACLE WEST CAPITAL CORPORATION
2012 LONG-TERM INCENTIVE PLAN
General
             As we describe in the CD&A, equity-based long-term compensation is an important element of our compensation program. In the past few years, we have issued long-term equity incentive awards under the 2007 Plan. In January 2012, the Board of Directors, upon recommendation of the Human Resources Committee, approved the Pinnacle West Capital Corporation 2012 Long-Term Incentive Plan (the "2012 Plan"), subject to shareholder approval at the 2012 Annual Meeting. If shareholder approval is obtained, the 2012 Plan will become effective on the date approved by the Board (the "Effective Date").
             The 2012 Plan is designed to supersede and replace the Pinnacle West Capital Corporation 2002 Long-Term Incentive Plan (the "2002 Plan") and the 2007 Plan (collectively, the "Prior Plans") maintained by the Company, provided that the Prior Plans shall remain in effect until all awards granted pursuant to such Prior Plans have been exercised, forfeited, canceled, expired or otherwise terminated in accordance with the terms of such awards. No awards will be granted under any Prior Plan after the approval of the 2012 Plan by the shareholders.
             The 2012 Plan provides for the grant of restricted stock, restricted stock units, stock grants, stock units, dividend equivalents, performance shares, performance share units, performance cash, incentive and non-qualified stock options, and stock appreciation rights ("SARs") to eligible individuals. The 2012 Plan also allows the Human Resources Committee to grant awards that are intended to qualify for the "performance-based compensation" exception to the $1,000,000 limitation on the deduction of compensation imposed by Section 162(m) of the Code.
             The Board believes that the 2012 Plan will promote the success, and enhance the value, of the Company by linking the personal interests of participants to those of Company shareholders. The Board also believes that the 2012 Plan will strengthen the Company's ability to motivate, attract, and retain employees upon whom the successful operation of the Company is largely dependent.
             The Company believes the following features of the 2012 Plan are consistent with the goals described above while providing appropriate limitations on the operation of the 2012 Plan:
•
Limitation on Repricing .   The 2012 Plan prohibits the direct and indirect repricing of previously granted options and SARs without prior shareholder approval.
•
No Discounted Options or SARs .   The 2012 Plan includes an express requirement that all options and SARs be issued with an exercise price that is not less than the fair market value of a share of Company stock on the grant date.
•
No Payment of Dividend Equivalents for Awards that Vest Based on Performance Goals until Performance Goals are Achieved .   The 2012 Plan precludes the payment of dividend equivalent awards for any restricted stock unit award that vests based on the achievement of performance goals, or with respect to a performance share unit or performance share award, unless and until the participant attains the applicable performance goals.
•
Limitation on Awards with Rapid or No Vesting .   The 2012 Plan provides that no more than five percent (in the aggregate) of the shares of stock available for grant under the 2012 Plan may be subject to the following types of awards: stock grants or stock units other than those
- 62 -

Table of Contents
awarded to members of the Board or members of the board of APS pursuant to regular retainer agreements; options that become fully vested prior to the third anniversary of the date of grant; SARs that become fully vested prior to the third anniversary of the date of grant; restricted stock or restricted stock unit awards that vest solely based on time-based vesting restrictions and which vest in less than three years from the date of grant; restricted stock or restricted stock unit awards that are subject to performance-based vesting and which vest before the expiration of the one-year period following the date of grant; and performance shares or performance share unit awards that fully vest before the expiration of the one-year period following the date of grant. Awards may vest in increments during the applicable three-year or one-year vesting periods described above. There are limited exceptions to the minimum vesting periods described in Section 14.1 of the 2012 Plan, which is attached as Appendix A.

Forfeiture and Recapture of Awards .   The award agreement for any award granted pursuant to the 2012 Plan will provide for the recapture or clawback of all or any portion of the award to comply with applicable law in effect on the date of the award agreement, including, but not limited to, the Dodd-Frank Wall Street Reform and Consumer Protection Act.
•
Approval Every Five Years .   On average, the Company has submitted a long-term equity incentive plan to the shareholders every five years. We anticipate that the 2012 Plan will have sufficient shares to cover at least five more years.
             A summary of the 2012 Plan's principal provisions is set forth below. The summary is qualified by reference to the full text of the 2012 Plan, which is attached as Appendix A.
Summary of Plan Features
Administration
             The 2012 Plan will be administered by the Human Resources Committee. The Human Resources Committee shall consist of at least two directors each of whom qualifies as a "non-employee director" as defined in Rule 16b-3(b)(3) of the Exchange Act, and an "outside director" under Section 162(m) of the Code. The Human Resources Committee's powers are described in Section 3.3 of the 2012 Plan and include, but are not limited to, determining eligibility to receive an award, determining the amount and types of awards that may be granted to a participant, and determining all other terms and conditions that apply to awards.
Eligibility
             Persons eligible to participate in the 2012 Plan include all employees, officers and Board members of the Company and its affiliates. In addition, on a case-by-case basis, the Human Resources Committee may grant awards to consultants and advisors to the Company and its affiliates subject to terms and conditions determined by the Human Resources Committee. Awards may also be made to prospective members of the Board, employees, officers, consultants or advisors. Such awards must specifically provide that no portion of the award will vest, become exercisable or be issued prior to the date on which the individual becomes employed or begins providing services to the Company or its subsidiaries.
Shares Available Under the 2012 Plan
             The aggregate number of shares of stock reserved and available for issuance pursuant to the 2012 Plan shall be 4,595,500 shares of the Company's common stock. The number of shares is substantially equivalent to and does not exceed the number of authorized and unissued shares under the current 2007 Plan. This share award pool will be reduced by one share for each share that is subject to
- 63 -

Table of Contents
any award granted under any Prior Plan in the period beginning on January 1, 2012 and ending on the date the shareholders approve the 2012 Plan. The amount of stock reserved for issuance pursuant to the 2012 Plan is subject to proportionate adjustment by the Human Resources Committee in the event of any issuance of rights or warrants to purchase securities, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other distribution with respect to the shares of stock, or any similar corporate transaction or event in respect of the stock.
             For purposes of calculating the number of shares of stock available for awards under the 2012 Plan, the following share counting rules shall apply:
•
Shares of stock that are potentially deliverable under any award granted under the 2012 Plan, or any award outstanding under any Prior Plan on or after December 31, 2011, that expires or is cancelled, forfeited, or otherwise terminated without a delivery of such shares will not be counted against the limit of shares available for issuance under the 2012 Plan and will again be available for grant under the 2012 Plan.
•
Shares of stock that could have been issued in connection with an award but are not delivered because such award is settled in cash, will not be counted against the limit of shares available for issuance under the 2012 Plan and will again be available for grant under the 2012 Plan.
•
Dividend equivalent awards that are paid in cash will not be counted against the limit of shares available for issuance under the 2012 Plan.
•
The exercise of a stock-settled SAR or net-cashless exercise of an option (or a portion thereof) will reduce the number of shares of stock available for issuance under the 2012 Plan by the entire number of shares of stock subject to that SAR or option (or applicable portion thereof), even though a smaller number of shares of stock will be issued upon such an exercise.
•
Shares of stock tendered to pay the exercise price of an option or tendered or withheld to satisfy a tax withholding obligation arising in connection with an award will not become available for grant or sale under the 2012 Plan.
•
Shares of stock purchased on the open market with cash proceeds generated by the exercise of an option will not increase or replenish the number of shares available for grant.
             The Human Resources Committee may adopt such other reasonable rules and procedures as it deems to be appropriate for purposes of determining the number of shares of stock that are available for awards under the 2012 Plan.
Limitation on Awards to Participants
             No more than 500,000 shares of stock may be subject to stock option or SAR awards granted to any one participant during any one calendar year. The maximum number of shares of stock that may be issued as incentive stock options under the 2012 Plan is 1,000,000. The maximum performance-based award (other than a performance cash award) payable to any one participant pursuant to the 2012 Plan during a 12-month performance period is 500,000 shares of stock or the cash equivalent. The maximum performance cash award payable to any one participant pursuant to the 2012 Plan for any 12-month performance period is $10,000,000. If a performance period is less than or exceeds 12 months, the limitations described in the two preceding sentences will be reduced or increased proportionately, as the case may be. As of March 16, 2012, the stock's closing price on the New York Stock Exchange was $47.02 per share.

Awards
             Each of the following types of awards may be granted pursuant to the 2012 Plan:
              Restricted Stock .     A restricted stock award gives the participant the right to receive a specified number of shares of stock at a purchase price determined by the Human Resources Committee (including and typically zero). Restricted stock shall be subject to such restrictions on transferability and other restrictions as the Human Resources Committee may impose. Except as otherwise provided by the Human Resources Committee, during the restriction period, participants holding shares of restricted stock may not exercise voting rights with respect to such shares. These restrictions may lapse separately or in combination at such times, in such circumstances, in such installments, or otherwise, as the Human Resources Committee determines at the time of the grant of the award or thereafter. As a general rule, if a participant terminates employment when the stock is subject to restrictions, the participant forfeits the unvested restricted stock. The Human Resources Committee may, in its discretion, waive the restrictions in whole or in part in the event of a termination of employment.
              Restricted Stock Units .     A restricted stock unit award gives the participant the right to receive stock, or a cash payment equal to the fair market value of the stock (determined as of a specified date), subject to any vesting or other restrictions the Human Resources Committee deems appropriate. The restrictions will lapse in accordance with a schedule or other conditions as determined by the Human Resources Committee. As a general rule, if a participant terminates employment when the restricted stock units are subject to restrictions, the participant forfeits the unvested restricted stock units. The Human Resources Committee may, in its discretion, waive the restrictions in whole or in part.
              Stock Grant Awards .     A stock grant award gives the participant the right to receive, or the right to purchase at a predetermined price, shares of stock free from vesting restrictions. The purchase price, if any, for a stock grant award shall be payable in cash or other form of consideration acceptable to the Human Resources Committee. A stock grant award may be granted or sold as consideration for past services, other consideration or in lieu of cash compensation due to any participant.
              Stock Unit Awards .     A stock unit award gives the participant the right to receive a designated number of shares of stock, or a cash payment equal to the fair market value (determined as of a specified date) of a designated number of shares of stock, in the future free of any vesting restrictions. A stock unit award may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to any participant.
              Dividend Equivalent Awards .     A dividend equivalent award gives the participant the right to receive a credit when a dividend is declared on the Company's stock. Dividend equivalents are credited as of dividend payment dates during the period between the date of grant and the date the award is exercised, vests or expires. In no event may a dividend equivalent award made with respect to a restricted stock unit award that vests based on the achievement of performance goals, or with respect to a performance share unit or performance share award, be paid unless and until such award vests or is earned by satisfaction of the applicable performance goals. A dividend equivalent award shall initially be expressed in terms of cash or shares of stock, depending on the way in which the dividends to which it relates are declared. The Human Resources Committee will specify when the dividend equivalents will be converted to cash or stock, the formula for conversion and any restrictions or limitations on the conversion. Dividend equivalents will not be granted with respect to options or SARs.
              Performance Share Awards .     A performance share award gives the participant the right to receive a specified number of shares of stock if one or more performance goals specified by the Human Resources Committee are satisfied. Performance may be measured on a specific date or dates or over any period or periods as determined by the Human Resources Committee.
- 65 -

Table of Contents
              Performance Share Units .     A performance share unit award gives the participant the right to receive a specified number of shares of stock or cash in an amount equal to the fair market value of the stock (determined as of a specified date) if one or more performance goals specified by the Human Resources Committee are satisfied. Performance may be measured on a specified date or dates or over any period or periods as determined by the Human Resources Committee.
              Performance Cash .     A performance cash award gives the participant the right to receive a cash payment if certain performance goals as specified by the Human Resources Committee are satisfied. Performance may be measured on a specified date or dates or over any period or periods determined by the Human Resources Committee.
              Stock Options .     An option entitles the participant to purchase shares of stock in the future at a specified price. The Human Resources Committee may grant both incentive stock options and nonqualified stock options under the 2012 Plan. Incentive stock options will only be granted to participants who are employees. The exercise price of all stock options granted under the 2012 Plan will be at least 100% of the fair market value of the stock on the date that the option is granted. Stock options may be exercised as determined by the Human Resources Committee provided that the term of any option granted under the 2012 Plan shall not exceed ten years from the date of grant. The exercise price for any option shall be paid in cash or shares of stock held longer than six months, however, the Human Resources Committee may prescribe other methods by which the exercise price of an option may be paid and the methods by which shares of stock may be delivered to participants; however, the exercise price may not be paid with a promissory note. The Human Resources Committee may not reprice options previously granted under the 2012 Plan.
              Stock Appreciation Rights .     A SAR entitles the participant to share in the appreciation on one share of stock. Appreciation is calculated as the excess of (i) the fair market value on the date of exercise over (ii) the base value of the SAR as determined by the Human Resources Committee, which shall not be less than the fair market value on the date of grant (or such higher amount determined by the Human Resources Committee). Unless otherwise provided by the Human Resources Committee, SARs shall vest and become exercisable in three equal installments on the first, second and third anniversaries of the date of grant, expire on the earlier of a participant's termination of employment or the tenth anniversary of the date of grant and payment for SARs shall be made in stock. The Human Resources Committee will determine the terms and conditions of any SAR at the time of the grant. A SAR may not be amended, modified or repriced to reduce the exercise price after the date of grant.
              Performance-Based Awards .     When the Human Resources Committee grants restricted stock, restricted stock units, stock grants, stock units, dividend equivalent awards, performance shares, performance share units, and performance cash awards, it may designate the awards as "performance-based awards." Performance-based awards are subject to the provisions of Article 13 of the 2012 Plan, which are designed to qualify the awards for the "performance-based compensation" exception to the limitations on the deduction of compensation imposed by Section 162(m) of the Code. Section 162(m) of the Code only applies to "covered employees," as defined in Section 162(m). Only covered employees will receive awards that will be classified as performance-based awards.
             A covered employee is only entitled to receive payment for a performance-based award for a given performance period to the extent that pre-established performance goals set by the Human Resources Committee for the performance period are satisfied. The Human Resources Committee will establish the performance goals for a particular performance period in writing no later than ninety days after the commencement of the performance period for a given award, provided that the outcome is substantially uncertain at the time the Human Resources Committee establishes the performance goal. In no event will the Human Resources Committee establish a performance goal for a given award after 25% of the performance period for such award has elapsed.
- 66 -

Table of Contents
             The pre-established performance goals must be based on one or more of the following performance criteria: EBITDA; EBIT; costs; operating income; net income; cash flow; operating cash flow; net cash flow; fuel cost per million BTU; costs per kilowatt hour; retained earnings; budget achievement; return on equity; return on assets; return on capital employed; return on invested capital; cash available to the Company from an affiliate or affiliates; expense spending; O&M expense; O&M or capital per kilowatt hour; gross margin; net margin; market capitalization; customer satisfaction; revenues; financial return ratios; market share; shareholder return and/or value (including but not limited to total shareholder return); operating profits (including earnings before or after income taxes, depreciation and amortization); net profits; earnings per share; earnings per share growth; profit returns and margins; stock price; working capital; business trends; production cost; project milestones; capacity utilization; quality; economic value added; plant and equipment performance; operating efficiency; diversity; debt; dividends; bond ratings; corporate governance; and health and safety (including environmental health and safety). Any of the performance criteria may be measured either in absolute terms or as compared to any incremental increase or as compared to results of a peer group, indices, or any other basket of companies. The Human Resources Committee shall, within the time periods prescribed by Section 162(m), define in an objective fashion the manner of calculating the performance criteria it selects to use for a particular performance period for a particular participant.
             With respect to any performance-based award granted to a covered employee, the Human Resources Committee has the discretion to select the length of the performance period (which may be one or more periods of time of varying and overlapping durations, over which the attainment of one or more performance goals will be measured), the type of performance-based award to be issued, the kind and/or level of performance goal or goals and whether the performance goal or goals apply to the Company, an affiliate or any division or business unit of any of them, or to the individual participant or any group of participants. The Human Resources Committee also has the discretion to evaluate the achievement of the performance goals in a manner that includes or excludes certain events that may occur during the performance period, as described in Section 13.5 of the 2012 Plan. The Human Resources Committee has the sole discretion to decrease the amount of compensation payable pursuant to any performance-based award, but the Human Resources Committee may not increase the compensation payable pursuant to any performance-based award. The Human Resources Committee must certify in writing prior to the payment of any performance-based award that the performance goals and any other material terms and conditions precedent to such payment have been satisfied.
             The pre-established performance criteria will be subject to shareholder approval again in 2017 if (as is currently the case) shareholder approval is then required to maintain the tax-deductible nature of future performance-based awards under the 2012 Plan.
Prohibition on Repricing
             The 2012 Plan includes provisions that prohibit the Human Resources Committee from directly or indirectly repricing previously granted options or SARs (reduction in option exercise price or SAR grant price, surrender in exchange for cash or another award under the 2012 Plan, or surrender or exchange for another option or SAR with a lower exercise or grant price) without shareholder approval.
Non-transferability
             As a general rule, awards granted pursuant to the 2012 Plan may not be transferred by a participant, except by will or by the laws of descent or distribution. The Human Resources Committee, in its discretion, may permit the transfer of any award to a family member or family trust.
Clawback of Awards
             The award agreement for any award granted pursuant to the 2012 Plan will provide for the recapture or clawback of all or any portion of the award to comply with applicable law in effect on the
- 67 -

Table of Contents
date of the award agreement, including, but not limited to, the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Human Resources Committee also may include other clawback provisions in the award agreement as it determines to be appropriate. By accepting an award, each participant in the 2012 Plan agrees to be bound by, and comply with, the terms of any such recapture or clawback provisions and with any Company request or demand for recapture or clawback.
Change of Control
             Unless the Human Resources Committee, with the approval of the Board, provides otherwise in an award agreement, if a change of control occurs, immediately prior to the change of control:
•
Any time-based or other restrictions imposed on restricted stock or restricted stock unit awards shall lapse and all restricted stock units and stock unit awards shall become immediately payable and shall be paid in stock or cash, in accordance with the terms of the applicable award agreement.
•
Performance shares or performance share unit awards that are payable in stock shall be converted to stock grant awards, which shall be immediately vested. In converting performance shares or performance share units to a stock grant, the participants shall receive the number of shares of stock that would have been earned at the target level of performance, unless the Human Resources Committee determines that a higher level of attained performance is reasonably ascertainable as of a specified date prior to the closing of the change of control transaction.
•
Any performance share unit awards that are payable in cash shall become immediately vested. Participants then shall generally receive a cash payment equal to the fair market value of the specified number of shares of stock payable pursuant to the award at the target level of performance, unless the Human Resources Committee determines that a higher level of attained performance is reasonably ascertainable as of a specified date prior to the closing of the change of control transaction.
•
Performance cash awards shall generally be deemed to be satisfied and earned at the target level of performance, unless the Human Resources Committee determines that a higher level of attained performance is reasonably ascertainable as of a specified date prior to the closing of the change of control transaction.
•
Any dividend equivalent awards shall be paid in cash or stock as determined in accordance with the applicable award agreement.
•
If an award is subject to Section 409A of the Code, a change of control may not result in the acceleration of the timing of any payment unless the transaction that results in the change of control also constitutes a "change of control event" as such term is used in the applicable Treasury Regulations. If due to the above provisions the payment of an award may not be accelerated, the Board, prior to the change of control, shall take such action as it in good faith determines to be necessary to assure that there will be no material impairment to either the value of the award to the participant or the participant's opportunity for future appreciation in respect of such award.
•
Any and all options and SARs shall become exercisable immediately before the closing of the change of control transaction. If pursuant to the terms of the award agreement, a SAR is to be paid in cash, the SAR will be deemed to be exercised on the closing of the transaction that results in the change of control and a participant will receive the resulting cash payment within ten days following the closing of the change of control transaction.
              Board Override .     Notwithstanding the foregoing change of control provisions, prior to a change of control, the Board may determine that no change of control shall be deemed to have occurred or that some or all of the enhancements to the rights of participants described above shall not apply to specified awards. The Board may exercise such override authority only if, before or immediately upon the occurrence of the specified event that would otherwise constitute a change of control, the Board, as
- 68 -

Table of Contents
constituted prior to the change of control, reasonably concludes, in good faith, that: (i) participants holding awards affected by action of the Board override shall be protected by legally binding obligations of the Company or the surviving entity or the parent thereof because such awards (A) shall remain outstanding following consummation of all transactions involved in or contemplated by such change of control or (B) shall be assumed and adjusted by the surviving entity resulting from such transactions or the parent thereof, or (C) shall be exchanged for new awards issued by the surviving entity resulting from such transaction or the parent thereof; and (ii) changes in the terms of the award resulting from such transactions will not materially impair the value of the awards to the participants or their opportunity for future appreciation in respect of such awards. The Board may exercise such override authority with respect to an award which the Company concludes is subject to (and not excepted from) the requirements of Section 409A of the Code only in a manner and to the extent permissible under Section 409A. The Committee took into account this override provision in its recommendation to the Board for approval of the 2012 Plan.
Amendment and Termination
             The Human Resources Committee, with the Board's approval, may terminate, amend, or modify the 2012 Plan at any time, except where shareholder approval for an amendment is required by applicable law, regulation or stock exchange rule. Except as provided in the next sentence, no amendment, modification, or termination of the 2012 Plan or any award agreement shall in any material manner adversely affect any award previously granted under the 2012 Plan without the consent of the participant. The participant's consent is unnecessary if, among other things, the change is required to cause the benefits under the 2012 Plan to (a) qualify as performance-based compensation within the meaning of Section 162(m) of the Code and applicable regulations or other interpretive authority or (b) comply with the provisions of Section 409A of the Code.
             The 2012 Plan will terminate on the tenth anniversary of the Effective Date. In no event may an award be granted under the 2012 Plan on or after the tenth anniversary of the Effective Date. Awards outstanding on the tenth anniversary of the Effective Date will remain in effect according to the terms of the award agreement and the 2012 Plan.
Tax Withholding
             The Company will have the power to withhold, or require a participant to remit to the Company, an amount sufficient to satisfy federal, state, and local withholding tax requirements on any award under the 2012 Plan.
Federal Income Tax Consequences
             This is a brief summary of the principal federal income tax consequences of certain transactions under the 2012 Plan based on federal income tax laws in effect on January 1, 2012. This summary is not intended to be exhaustive and does not describe state, local and foreign income taxes which may also be applicable.
             As a general rule, with the exception of a stock grant, a participant will not recognize taxable income with respect to any award at the time of grant. A participant will recognize ordinary taxable income on a stock grant award at the time of grant.
             Upon exercise of a nonqualified stock option, the lapse of restrictions on restricted stock, or upon the payment of SARs, restricted stock units, stock grants, stock units, performance shares, performance share units, performance cash, or dividend equivalents, the participant will recognize ordinary taxable income in an amount equal to the difference between the amount paid for the award, if any, and the fair market value of the stock or amount received on the date of exercise, lapse of
- 69 -

Table of Contents
restriction, or payment. The Company will be entitled to a concurrent deduction equal to the ordinary income recognized by the participant.
             A participant who is granted an incentive stock option will not recognize taxable income at the time of exercise. However, the excess of the stock's fair market value over the option price could be subject to the alternative minimum tax in the year of exercise (assuming the stock received is not subject to a risk of forfeiture and is not transferable). If stock acquired upon exercise of an incentive stock option is held for a minimum of two years from the date of grant and one year from the date of exercise, the gain or loss (in an amount equal to the difference between the sales price and the exercise price) upon disposition of the stock will be treated as a long-term capital gain or loss, and the Company will not be entitled to any deduction. If the holding period requirements are not met, the incentive stock option will not meet the requirements for this favored tax treatment and the tax consequences described for nonqualified stock options will apply.
             Section 409A of the Code, among other things, expanded the definition of deferred compensation arrangements to include, for example, below market option and SAR grants, restricted stock units, performance shares, performance share units, performance cash, dividend equivalents (in some circumstances) and stock unit awards. If awards that are subject to Section 409A of the Code fail to comply with Section 409A, a participant must include in ordinary income all deferred compensation conferred by the award, pay interest from the date of the deferral and pay an additional 20% tax. The Company intends (but does not and cannot guarantee) that awards granted under the 2012 Plan will comply with the requirements of Section 409A or an exception thereto and intends to administer and interpret the 2012 Plan in such a manner.
New Plan Benefits
             Benefits under the 2012 Plan will depend on the Human Resources Committee's actions and the fair market value of common stock at various future dates. Consequently, it is not possible to determine the future benefits that will be received by 2012 Plan participants. However, in February 2012, the Human Resources Committee granted to the Named Executive Officers performance shares and RSUs. The performance share grants use the same performance metrics as set forth in the CD&A for the 2011 Performance Shares (except the J.D. Power Residential Survey changed from the Western Region to the National Large Segment) but the performance period is from January 1, 2012 through December 31, 2014. The RSUs vest in four equal, annual installments beginning on February 20, 2013. The Named Executive Officers received the following base grant for the performance shares: Mr. Brandt – 41,772; Mr. Hatfield – 5,802; Mr. Edington – 5,802; Mr. Falck – 8,122; and Mr. Robinson – 16,246; and the following RSUs: Mr. Brandt – 34,184; Mr. Hatfield – 4,752; Mr. Edington – 4,752; Mr. Falck – 6,648; and Mr. Robinson – 13,296. The grants were made under the 2012 Plan, but if the 2012 Plan is not approved by the shareholders, these grants will automatically be made under the 2007 Plan.
Vote Required
             Adoption of the 2012 Plan requires approval by holders of a majority of the outstanding shares of Company stock who are present, or represented, and entitled to vote thereon, at the 2012 Annual Meeting, provided the total votes cast with respect to this proposal represent over fifty percent (50%) of the shares of common stock entitled to vote on the proposal.

1  This amount includes shares subject to outstanding options as well as shares subject to outstanding performance share awards and restricted stock unit awards at the maximum amount of shares issuable under such awards. However, payout of the performance share awards is contingent on the Company reaching certain levels of performance during a three-year performance period. If the performance criteria for these awards are not fully satisfied, the award recipient will receive less than the maximum number of shares available under these grants and may receive nothing from these grants.
2  The weighted average exercise price in this column does not take performance share awards or restricted stock unit awards into account, as those awards have no exercise price.
3 Awards can take the form of options, stock appreciation rights, restricted stock, performance shares, performance share units, performance cash, stock grants, dividend equivalents, and restricted stock units.
              Equity Compensation Plans Approved By Security Holders
             Amounts in column (a) in the table above include shares subject to awards outstanding under the Prior Plans that were previously approved by our shareholders: (a) the 2002 Plan, under which no new stock awards may be granted; and (b) the 2007 Plan, which was approved by our shareholders at our 2007 annual meeting of shareholders. Although we cannot issue additional awards under the 2002 Plan, shares subject to outstanding awards under the 2002 Plan that expire or are cancelled or terminated are added to the number of shares of stock available for issuance under the 2007 Plan. See Note 16 of the Notes to Consolidated Financial Statements in the 2011 Form 10-K for additional information regarding these plans.
              Equity Compensation Plans Not Approved By Security Holders
             The Company does not have any equity compensation plans under which shares can still be issued that have not been approved by shareholders.

 Amendments to Existing Award Agreements
             As stated in the CD&A under the heading "Executive Compensation Components – Long-Term Incentives – Amendments to Existing Award Agreements," we amended all outstanding award
- 71 -

Table of Contents
agreements under the 2007 Plan to provide a more customary treatment of the awards in the event of a change of control. The amendments provide as follows:
              Performance Share Awards .     Upon the closing, or in anticipation but contingent upon the closing, of a transaction that results in a change of control, each performance share award granted under the 2007 Plan will be converted to either a restricted stock unit award or cash, at the election of the participant. Both the restricted stock unit award and the cash equivalent, as the case may be, will become vested upon the closing of the change of control transaction.
             If the participant elects to convert the performance share to a restricted stock unit award, the participant will receive the number of restricted stock units equal to the number of shares of stock that would have been earned at the target level of performance, unless the Human Resources Committee determines that a higher level of attained performance is reasonably ascertainable as of a specified date prior to the closing of the change of control transaction. The restricted stock units will then be converted into an award relating to the publicly traded stock of the surviving entity or its parent company. The value of the shares of stock subject to the converted award shall equal the value of the consideration received in connection with the transaction that results in the change of control by a shareholder of the Company holding the same number of shares of stock as the number of restricted stock units as calculated above.
             If a participant elects to convert the performance share awards granted under the 2007 Plan to cash, the participant will receive a cash payment equal to the fair market value as of the date of closing of the change of control transaction for the specified number of shares of stock equal to the number of shares of stock that would have been earned at the target level of performance, unless the Human Resources Committee determines that a higher level of attained performance is reasonably ascertainable as of a specified date prior to the closing of the change of control transaction.
              RSU Awards .     All RSU awards granted under the 2007 Plan will become fully vested upon the closing, or in anticipation but contingent upon the closing, of a transaction that results in a change of control.
             RSU awards that are not subject to Section 409A of the Code will become immediately payable and will be paid in stock or cash, in accordance with the terms of the applicable award agreement.
             If the Company concludes that a RSU award granted under the 2007 Plan is subject to Section 409A of the Code, the RSU award will be converted into a restricted stock unit award relating to (and expressed in terms of) the publicly traded stock of the surviving entity or its parent company or cash, as elected by the participant. Payment for the converted restricted stock units shall then be made at the time or times otherwise specified in the award agreement. If the participant elects to convert the award into an award relating to the publicly traded stock of the surviving entity or its parent company, the value of the shares of stock subject to the converted award will equal the value of the consideration received in connection with the transaction that results in the change of control by a shareholder of the Company holding the same number of shares of stock that are subject to the award.
             If a participant elects to convert a RSU award into cash, the amount of cash payable will be equal to the value of the consideration received in connection with the closing of the change of control transaction by a shareholder of the Company holding the same number of shares of stock that are subject to the award.
              Board Override .     Prior to a change of control, the Board, may determine that no change of control shall be deemed to have occurred or that some or all of the enhancements to the rights of participants described above, shall not apply to specified awards of performance shares or RSUs. The Board may exercise such override authority only if, before or immediately upon the occurrence of the
- 72 -

Table of Contents
specified event that would otherwise constitute a change of control, the Board, as constituted prior to the change of control, reasonably concludes, in good faith, that: (i) participants holding awards affected by action of the Board override shall be protected by legally binding obligations of the Company or the surviving entity or the parent thereof because such awards (A) shall remain outstanding following consummation of all transactions involved in or contemplated by such change of control or (B) shall be assumed and adjusted by the surviving entity resulting from such transactions or the parent thereof, or (C) shall be exchanged for new awards issued by the surviving entity resulting from such transactions or the parent thereof; and (ii) changes in the terms of the award resulting from such transactions will not materially impair the value of the awards to the participants or their opportunity for future appreciation in respect of such awards.

 PROPOSAL 3 – ADVISORY VOTE ON EXECUTIVE COMPENSATION
             The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") was signed into law on July 21, 2010. The Dodd-Frank Act requires U.S. public corporations to provide for an advisory (non-binding) vote on executive compensation ("Say-on-Pay").
             As discussed in more detail in our CD&A and the accompanying tables and narrative, the Company has designed its executive compensation program to align executives' interests with those of our shareholders, make executives accountable for business and individual performance, retain key employees, and attract, retain and reward the executive talent required to achieve our corporate objectives and to increase long-term shareholder value. We believe that our compensation policies and practices promote a pay-for-performance philosophy and, as such, are aligned with the interests of our shareholders.
             In deciding how to vote on this proposal, the Board points out the following factors, many of which are more fully discussed in the CD&A:
•
Our Human Resources Committee has designed the compensation packages for our Named Executive Officers to depend significantly on the achievement of performance goals that the Human Resources Committee believes drive long-term shareholder value;
•
The Company had a highly successful year in 2011, as discussed under "Overview of 2011 Company Performance;"
•
Our pay practices are designed not to encourage management to take unacceptable risks;
•
We engage in continual benchmarking in order to confirm that our programs are comparable to the companies in our Comparator Group; and
•
We believe the Company's executive compensation program is well suited to promote the Company's objectives in both the short and long-term.
             The Board strongly endorses the Company's executive compensation program and recommends that the shareholders vote in favor of the following resolution:
RESOLVED, that the compensation paid to the Company's Named Executive Officers as disclosed in this Proxy Statement in the CD&A, the compensation tables and the narrative discussion, is hereby approved.
             Because your vote is advisory, it will not be binding upon the Human Resources Committee or the Board. However, we value our shareholders' opinions, and we will consider the outcome of the vote when determining future executive compensation arrangements.

its next scheduled meeting. All of the services performed by D&T in 2011 for the Company were pre-approved by the Audit Committee.

 REPORT OF THE AUDIT COMMITTEE
             In accordance with its written charter adopted by the Board, the primary function of the Audit Committee is to assist Board oversight of: (a) the integrity of the Company's financial statements; (b) the independent accountants' qualifications and independence; (c) the performance of the Company's internal audit function and independent accountants; and (d) general compliance by the Company with legal and regulatory requirements that may have a material impact on the financial statements of the Company.
The Audit Committee reports as follows:
             1.     The Audit Committee has discussed and reviewed the audited financial statements of the Company as of and for the fiscal year ended December 31, 2011, with the Company's management and the independent accountants, D&T. The Audit Committee is directly responsible for the oversight of the Company's independent accountants. Management is responsible for the Company's financial reporting process, including the Company's system of internal controls, and for the preparation of financial statements in accordance with accounting principles generally accepted in the United States of America. The independent accountants are responsible for auditing and rendering an opinion on those financial statements, as well as auditing certain aspects of the Company's internal controls. The Audit Committee's responsibility is to monitor these processes.
             2.     The Audit Committee has discussed with D&T all communications required by auditing standards generally accepted in the United States of America and SEC regulations, including those described in Statement on Auditing Standards No. 61, as amended, as adopted by the Public Company Accounting Oversight Board in Rule 3200T.
             3.     The Audit Committee has obtained from D&T and reviewed the written disclosures and the letter required by applicable requirements of the Public Accounting Oversight Board regarding the independent accountants' communications with the Audit Committee concerning independence. The Committee discussed with D&T any relationships that may impact D&T's objectivity and independence and satisfied itself as to the accountants' independence.
             4.     Based on the foregoing, the Audit Committee has recommended to the Board that the Company's audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2011, for filing with the SEC.

 ARTICLE 4
SHARES SUBJECT TO THE PLAN
             4.1             NUMBER OF SHARES .    Subject to the possible increases provided by Section 4.2 with respect to shares of Stock that become available under the Prior Plans and adjustments as provided in Section 4.4 , the aggregate number of shares of Stock reserved and available for grant (or to be used to determine the value of an Award payable in cash) pursuant to the Plan shall be 4,595,500. The number of shares authorized for issuance shall be reduced by one share for each share that is subject to any award granted under any Prior Plan in the period beginning on January 1, 2012 and ending on the date the shareholders approve the Plan.
             4.2             SHARE COUNTING .    For purposes of determining the number of shares of Stock available for Award under the Plan from time-to-time:
                             (a)           In the event any Award granted under this Plan, or any award outstanding under any Prior Plan on or after December 31, 2011, shall be forfeited, terminate or be canceled or expire, the number of shares of Stock subject to such Award or Prior Plan award, to the extent of any such forfeiture, termination, cancellation or expiration, shall thereafter be available for grant under the Plan.
                             (b)           If shares of Stock are not delivered in connection with any Award because the Award is settled in cash, such shares shall not be deemed to have been delivered for purposes of determining the maximum number of shares of Stock available for delivery under the Plan and will again be available for grant.
                             (c)           The exercise of a stock-settled SAR or broker-assisted "cashless" exercise of an Option (or a portion thereof) will reduce the number of shares of Stock available for issuance by the entire number of shares of Stock subject to that SAR or Option (or applicable portion thereof), even though a smaller number of shares of Stock will be issued upon such an exercise.
                             (d)           Dividend Equivalent Awards paid in Stock shall be counted against the shares available for issuance under the Plan by the number of shares of Stock used to satisfy such Dividend Equivalent Award.
                             (e)           Shares of Stock tendered to pay the exercise price of an Option or tendered, withheld or otherwise relinquished by the Participant to satisfy a tax withholding obligation arising in connection with any Award will not become available for grant under the Plan. Moreover, shares of Stock purchased on the open market with cash proceeds generated by the exercise of an Option will not increase or replenish the number of shares available for grant.
                             (f)            If the provisions of this Section 4.2 are inconsistent with the requirements of any regulations promulgated by the Internal Revenue Service pursuant to Section 422 of the Code, the provisions of such regulations shall control over the provisions of this Section 4.2 , but only as this Section 4.2 applies to Incentive Stock Options.
A-3

Table of Contents
                             (g)           The Committee may adopt such other reasonable rules and procedures as it deems to be appropriate for purposes of determining the number of shares of Stock that are available for grant pursuant to Section 4.1 .
             4.3             STOCK DISTRIBUTED .    Any shares of Stock delivered pursuant to an Award may consist, in whole or in part, of authorized but unissued Stock or treasury Stock or Stock purchased on the open market.
             4.4             ADJUSTMENTS .    In the event of any issuance of rights or warrants to purchase securities, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other distribution with respect to the shares of Stock, or any similar corporate transaction or event in respect of the Stock, then the Committee shall, in the manner and to the extent that it deems appropriate and equitable to the Participants and not inconsistent with the terms of this Plan, cause a proportionate adjustment to be made in (i) the maximum numbers of shares of Stock provided in Section 4.1 , (ii) the maximum numbers of shares of Stock set forth in Sections 11.1, 11.2, 12.1 and 13.9 and any other similar numeric limit expressed in the Plan, (iii) the number of shares of Stock, units, or other rights subject to the then-outstanding Awards, (iv) the price, if applicable, for each share of Stock or unit or other right subject to then outstanding Awards without change in the aggregate purchase price or value as to which such Awards remain exercisable or subject to restrictions, (v) the performance targets or goals appropriate to any outstanding Awards (subject to such limitations as appropriate for Performance-Based Awards), or (vi) any other terms of an Award that are affected by the event. Moreover, in the event of any such transaction or occurrence, the Committee may provide in substitution for any or all outstanding Awards such alternative consideration (including cash) as it, in good faith, may determine to be equitable under the circumstances and may require in connection therewith the surrender of all Awards so replaced. The foregoing provisions of this Section 4.4 also apply to any merger, consolidation, liquidation, spin-off or split-off of the Company or any Affiliate, but only to the extent that the application of the provisions of this Section 4.4 are consistent with the provisions of Article 15 if such transaction constitutes a Change of Control. Any adjustments made pursuant to this Section 4.4 shall be made in a manner consistent with the requirements of Section 409A of the Code and, in the case of Incentive Stock Options, any such adjustments shall be made in a manner consistent with the requirements of Section 424(a) of the Code.
             4.5             NO OTHER RIGHTS .    Except as expressly provided in Article 9 or Article 15 , no Participant shall have any rights by reason of any merger, consolidation, liquidation, issuance of rights or warrants to purchase securities, recapitalization, reclassification, stock dividend, spin-off, split-off, stock split, reverse stock split or other distribution with respect to the shares of Stock, or any similar corporate transaction or event in respect of the Stock. Except as expressly provided in Article 15 , no issuance by the Company of shares of Stock of any class, or securities convertible into shares of Stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Stock subject to an Award or the exercise price of any Award.
             4.6             REPLACEMENT AWARDS .    In the event of any corporate transaction in which the Company or an Affiliate acquires a corporate entity which, at the time of such transaction, maintains an equity compensation plan pursuant to which awards of stock options, stock appreciation rights, restricted stock, performance shares, performance share units, stock grants, stock units, dividend equivalents, restricted stock units or any other form of equity based compensation are then outstanding (the "acquired plan"), the Committee may make Awards to assume, substitute or convert such outstanding awards in such manner as may be determined to be appropriate and equitable by the Committee; provided, however, that the number of shares of Stock subject to any Award shall always be a whole number by rounding any fractional share to the nearest whole share. Options or SARs issued pursuant to this Section 4.6 shall not be subject to the requirement that the exercise price of such Award not be less than the Fair Market Value of Stock on the date the Award is granted. Shares used in connection with an Award granted in substitution for an award outstanding under an acquired plan
A-4

Table of Contents
under this Section 4.6 shall not be counted against the number of shares of Stock reserved under this Plan under Section 4.1 . Any shares of Stock authorized and available for issuance under the acquired plan shall, subject to adjustment as described in Section 4.4 , be available for use in making Awards under this Plan with respect to persons eligible under such acquired plan, by virtue of the Company's assumption of such acquired plan, consistent with Rule 303A(8) of the New York Stock Exchange Listed Company Manual, as such Rule may be amended or replaced from time to time.

 ARTICLE 5

             5.1             ELIGIBILITY .    Persons eligible to participate in this Plan include members of the Board and employees and officers of the Company; members of the board of directors (or other governing board), officers and employees of any Affiliate; and members of the board of directors (or other governing board), officers and employees of any entity of which the Company or an Affiliate, directly or indirectly, owns 20% or more of the voting or economic interest. The Committee may determine on a case-by-case basis to make Awards under the Plan to consultants and advisers to the Company or any Affiliate on such terms as it may determine, consistent with the provisions of the Plan. Prospective Participants to whom Awards are granted in connection with written offers of an employment or service agreement with the Company or an Affiliate also may be granted Awards. The provisions of any Award granted to a prospective Participant must specifically provide that no portion of the Award will vest, become exercisable or be issued prior to the date on which such individual becomes employed by or begins providing services to the Company or any Affiliate.
             5.2             ACTUAL PARTICIPATION .    Subject to the provisions of the Plan, the Committee may, from time to time, select from among all eligible Participants those to whom Awards shall be granted and shall determine the nature and amount of each Award. No individual shall have any right to be selected to receive an Award, or having been so selected, to be selected to receive a future Award, except as otherwise provided by an agreement, the relevant provisions of which have been approved by the Committee.

 ARTICLE 6
GENERAL RULES APPLICABLE TO ALL AWARDS
             6.1             AWARD AGREEMENTS .    All Awards shall be evidenced by an Award Agreement. The Award Agreement shall include such terms and provisions as the Committee determines to be appropriate.

             6.2             STAND-ALONE AND TANDEM AWARDS .    Awards granted pursuant to the Plan may be granted either alone, in addition to, or in tandem with, any other Award granted pursuant to the Plan or any Prior Plan.

             6.3             TERM OF AWARD .    The term of each Award shall be for the period determined by the Committee, provided that in no event shall the term of any Option or Stock Appreciation Right exceed a period of ten years from the Date of Grant.
             6.4             TERMINATION OF SERVICE .    Subject to the provisions of this Plan, the Committee shall determine and set forth in the applicable Award Agreement the extent to which a Participant shall have the right to retain and/or exercise an Award following Termination of Employment (or Termination of Service in the case of a member of the Board). Such provisions need not be uniform among all types of Awards and may reflect distinctions based on the reasons for such terminations,

including but not limited to, death, Disability, a Change of Control, a termination for cause or reasons relating to the breach or threatened breach of restrictive covenants.
             6.5             FORM OF PAYMENT FOR AWARDS .    Subject to the terms of the Plan, the Award Agreement and any applicable law, payments or transfers to be made by the Company or an Affiliate on the grant, exercise or settlement of an Award may be made in such forms as the Committee determines at or after the time of grant, including, without limitation, cash, Stock, other Awards, or other property, or any combination, and may be made in a single payment or transfer, in installments, or on a deferred basis, in each case determined in accordance with rules adopted by the Committee.

RESTRICTED STOCK AND RESTRICTED STOCK UNIT AWARDS
             7.1             GRANT OF RESTRICTED STOCK .    
                             (a)            Issuance and Restrictions .    Restricted Stock shall be subject to such restrictions on transferability and other restrictions as the Committee may impose (including, without limitation, limitations on the right to receive dividends or vote the Restricted Stock). These restrictions may lapse separately or in combination at such times, in such circumstances, in such installments, or otherwise, as the Committee determines at the time of the grant of the Award or thereafter. Except as otherwise provided in the Award Agreement, Participants holding shares of Restricted Stock may not exercise voting rights with respect to the shares of Restricted Stock during the restriction period.
                             (b)            Forfeiture .    Except as otherwise determined by the Committee at the time of the grant of the Award or thereafter, upon a Termination of Employment (or Termination of Service in the case of a member of the Board) during the applicable restriction period, Restricted Stock that is at that time subject to restrictions shall be forfeited; provided, however, that the Committee may provide in any Restricted Stock Award Agreement that restrictions or forfeiture conditions relating to Restricted Stock will be waived in whole or in part in the event of a Termination of Employment (or Termination of Service in the case of a member of the Board) resulting from specified causes. The Committee also may waive in whole or in part any other restrictions or forfeiture conditions relating to a Restricted Stock Award.
                             (c)            Certificates for Restricted Stock .    Restricted Stock granted pursuant to the Plan may be evidenced in such manner as the Committee shall determine. If certificates representing shares of Restricted Stock are registered in the name of the Participant, the certificates must bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock, and the Company may retain physical possession of the certificate until such time as all applicable restrictions lapse.
             7.2             RESTRICTED STOCK UNIT AWARDS .    Restricted Stock Unit Awards will grant the Participant the right to receive a specified number of shares of Stock, or a cash payment equal to the Fair Market Value (determined as of a specified date) of a specified number of shares of Stock, subject to any vesting or other restrictions deemed appropriate by the Committee. These restrictions may lapse separately or in combination at such times, in such circumstances, in such installments, or otherwise, as the Committee determines at the time of the grant of the Award or thereafter. Except as otherwise determined by the Committee at the time of the grant of the Award or thereafter, upon a Termination of Employment (or Termination of Service in the case of a member of the Board) during the applicable restriction period, Restricted Stock Units that are at that time subject to restrictions shall be forfeited; provided, however, that the Committee may provide in any Restricted Stock Unit Award Agreement that restrictions or forfeiture conditions relating to Restricted Stock Units will be waived in whole or in part in the event of a Termination of Employment (or Termination of Service in the case of a member of the Board) resulting from specified causes. The Committee also may waive in whole or in part any

other restrictions or forfeiture conditions relating to a Restricted Stock Unit Award.

ARTICLE 13
PERFORMANCE-BASED AWARDS
             13.1      PURPOSE .    Section 162(m) of the Code limits the amount of the Company's deductions for compensation payable to Covered Employees to a specified amount per year. "Performance-based compensation" that meets the requirements set forth in Section 162(m) and the applicable regulations is not subject to this limitation. The purpose of this Article 13 is to enable the Committee to qualify some or all of the Awards granted pursuant to Articles 7, 8, 9 and 10 as "performance-based compensation" pursuant to Section 162(m) of the Code.
             If the Committee decides that a particular Award to a Covered Employee should qualify as "performance-based compensation," the Committee will provide in the Award Agreement or otherwise that the Award is intended to be a Performance-Based Award.
             13.2      APPLICABILITY .    This Article 13 shall apply only to Performance-Based Awards. If this Article 13 applies, its provisions control over any contrary provision contained in any other section of this Plan or any Award Agreement. The provisions of this Article 13 and any Award Agreement for a Performance-Based Award shall be interpreted in a manner consistent with the requirements of
A-10

Table of Contents
Section 162(m) and the applicable regulations. If any provision of this Plan or any Award Agreement for a Performance-Based Award does not comply with or is inconsistent with the requirements of Section 162(m) or the applicable regulations, such provision shall be construed or deemed amended to the extent necessary to conform to such requirements.
             13.3      DISCRETION OF COMMITTEE WITH RESPECT TO PERFORMANCE-BASED AWARDS .    With regard to a particular Performance Period, the Committee may select the length of such Performance Period, the type of Performance-Based Awards to be issued, the kind and/or level of the Performance Goal or Goals, and whether the Performance Goal or Goals is or are to apply to the Company, an Affiliate or any division or business unit thereof or the Participant or any group of Participants. Depending on the Performance Criteria used to establish the Performance Goals, the Performance Goals may be stated in terms of absolute levels or relative to another company or to an index or indices.
             13.4      ESTABLISHMENT OF PERFORMANCE GOALS .    A Performance-Based Award shall provide for payment only upon the attainment of one or more pre-established, objective Performance Goals. The Performance Goals, and the process by which they are established, shall satisfy all of the requirements of Section 162(m) and the applicable regulations. By way of illustration, but not limitation, the following requirements must be satisfied:
                         (a)       The Performance Goals shall be based solely on the Performance Criteria specifically identified in the Glossary;
                         (b)       The Performance Goals shall be considered to be pre-established only if the Performance Goals are established by the Committee in writing not later than ninety (90) days after the commencement of the Performance Period for such Award; provided that (i) the outcome must be substantially uncertain at the time the Committee establishes the Performance Goals, and (ii) in no event may the Committee establish the Performance Goals for any Performance-Based Award after 25% of the Performance Period for such Award has elapsed;
                         (c)       A Performance Goal will be considered to be objective only if a third party having knowledge of the relevant facts could determine whether the Performance Goal has been met;
                         (d)       The Performance Goal must state, in terms of an objective formula or standard, the method for computing the amount of compensation payable to the Covered Employee if the Goal is attained. For this purpose, the formula will be considered to be objective only if a third party having knowledge of the relevant performance results could calculate the amount to be paid to the Covered Employee; and
                         (e)       The objective formula or standard must preclude discretion to increase the amount of compensation payable that would otherwise be due upon attainment of the Performance Goal.
             13.5      PERFORMANCE EVALUATION; ADJUSTMENT OF GOALS .    At the time that a Performance-Based Award is first issued, the Committee, in the Award Agreement or in another written document, shall specify whether performance will be evaluated including or excluding the effect of any of the following events that occur during the Performance Period, as the Committee deems appropriate:
                         (a)       Decisions entered or settlements reached in litigation or regulatory proceedings;
                         (b)       The write down or sale of assets;
                         (c)       The impact of discontinued operations or any reorganization, liquidation or restructuring;
A-11

Table of Contents
                         (d)       The impact of changes in tax laws, accounting principles, regulatory actions or other laws affecting reported results;
                         (e)       Extraordinary non-recurring items as described in Accounting Principles Board Opinion No. 30 and/or in management's discussion and analysis of financial condition and results of operations appearing in the Company's annual or quarterly reports filed with the Securities and Exchange Commission in respect of the applicable year;
                         (f)        The impact of any mergers, acquisitions, spin-offs or other divestitures; and
                         (g)       Foreign exchange gains and losses.
The inclusion or exclusion of these items shall be expressed in a form that satisfies the requirements of Section 162(m) and the applicable regulations. The Committee also may, within the time prescribed by Section 162(m) and the applicable regulations, adjust or modify the calculation of Performance Goals for such Performance Period in order to prevent the dilution or enlargement of the rights of Participants (i) in the event of, or in anticipation of, any unusual or extraordinary corporate item, transaction, event, or development, or (ii) in recognition of, or in anticipation of, any other unusual or nonrecurring events affecting the Company, or the financial statements of the Company, or in response to, or in anticipation of, changes in applicable laws, regulations, accounting principles, or business conditions.
             13.6      ADJUSTMENT OF PERFORMANCE-BASED AWARDS .    The Committee may adjust the determinations of the degree of attainment (taking into account any adjustments required pursuant to Section 13.5 ) of the pre-established Performance Goals. Notwithstanding any provision herein to the contrary, the Committee may not make any adjustment or take any other action with respect to any Performance-Based Award that will increase the amount payable under any such Award. The Committee shall retain the power to adjust Performance-Based Awards downward or to otherwise reduce the amount payable with respect to any Performance-Based Award.
             13.7      CONTINUED EMPLOYMENT REQUIRED .    Unless otherwise provided in the relevant Award Agreement, a Participant must be an employee of the Company or an Affiliate on the day a Performance-Based Award for such Performance Period is paid to the Participant.
             13.8      CERTIFICATION BY COMMITTEE .    The payment for a Performance-Based Award shall not occur until the Committee certifies, in writing, that the pre-established Performance Goals and any other material terms and conditions precedent to such payment have been satisfied. Committee certification is not required for compensation that is attributable solely to the increase in the value of the Company's Stock.
             13.9      MAXIMUM AWARD PAYABLE .    The maximum Performance-Based Award (other than a Performance Cash Award) payable to any one Participant pursuant to the Plan for any Performance Period is 500,000 shares of Stock or the equivalent cash value. The maximum Performance Cash Award payable to any one Participant for any Performance Period is $10,000,000. If the Performance Period is less than or exceeds 12 months, the dollar and share limits expressed in the preceding sentences shall be reduced or increased proportionately, as the case may be. For example, if the Performance Period is three years, the limit shall be increased by multiplying it by three.
             13.10       MISCELLANEOUS .    The designation of a Covered Employee as a Participant for any Performance Period shall not in any manner entitle the Participant to receive a Performance-Based Award for such Performance Period. Moreover, designation of a Covered Employee as a Participant for a particular Performance Period shall not require designation of such Covered Employee as a Participant for any subsequent Performance Period.

OTHER PROVISIONS APPLICABLE TO ALL AWARDS
             14.1      LIMITATION ON AWARDS WITH RAPID OR NO VESTING .    No more than five percent in the aggregate of the shares of Stock available for grant or reference purposes pursuant to Section 4.1 may be subject to the following types of Awards:
                         (a)       Stock Grants or Stock Units other than those awarded to members of the Board or members of the board of directors of APS pursuant to regular retainer arrangements;
                         (b)       Options that become fully vested prior to the third anniversary of the Date of Grant;
                         (c)       SARs that becomes fully vested prior to the third anniversary of the Date of Grant;
                         (d)       Restricted Stock or Restricted Stock Units with respect to which the restrictions lapse solely based on the passage of time and which vest in less than three years;
                         (e)       Restricted Stock or Restricted Stock Units with respect to which the restrictions lapse based on the satisfaction of Performance Goals and that fully vest before the expiration of the one-year period following the Date of Grant; and
                         (f)        Performance Shares or Performance Share Units that fully vest before the expiration of the one-year period following the Date of Grant.
An Award will not be included in the aggregate Awards subject to the requirements of this Section solely because the Award Agreement provides for the immediate vesting of the Award upon a Participant's death or Disability or upon the occurrence of a Change of Control. In addition, replacement Awards granted pursuant to Section 4.6 shall be disregarded in calculating compliance with the limitations of this Section. In addition, an Award will not be included in the aggregate Awards subject to the requirements of this Section solely because the Award Agreement provides that an incremental portion of the Award may become vested proportionally during the vesting periods described above. For example, an Option or SAR that becomes vested in equal monthly, quarterly or annual increments over a period of three years will not be subject to the limitations of this Section.
             14.2      LIMITS ON TRANSFER .
                         (a)        General .    Except as provided in Section 14.2(b) or Section 14.3 , no right or interest of a Participant in any Award may be pledged, encumbered, or hypothecated to, or in favor of, any party other than the Company or an Affiliate, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Company or an Affiliate. Except as provided in Section 14.2(b) or Section 14.3 , and except as otherwise provided by the Committee, no Award shall be assigned, transferred, or otherwise disposed of by a Participant other than by will or the laws of descent and distribution or pursuant to a domestic relations order (that would otherwise qualify as a qualified domestic relations order as defined in the Code or Title I of ERISA but for the fact that the order pertains to an Award) in favor of a spouse or, if applicable, until the expiration of any period during which any restrictions are applicable or any Performance Period as determined by the Committee.
                         (b)        Transfers to Family Members .    The Committee shall have the authority to adopt a policy that is applicable to existing Awards, new Awards, or both, which permits a Participant to transfer Awards during his or her lifetime to any Family Member. In the event an Award is transferred as permitted by such policy, such transferred Award may not be subsequently transferred by the transferee (other than another transfer meeting the conditions set forth in the policy) except by will or the laws of

descent and distribution. A transferred Award shall continue to be governed by and subject to the terms and limitations of the Plan and relevant Award Agreement, and the transferee shall be entitled to the same rights as the Participant, as if the transfer had not taken place.
             14.3      BENEFICIARIES .    Notwithstanding Section 14.2 , a Participant may, in the manner determined by the Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any Award upon the Participant's death, and, in accordance with Section 11.2(b)(3) , upon the Participant's Disability. A beneficiary, legal guardian, legal representative, or other person claiming any rights pursuant to the Plan is subject to all terms and conditions of the Plan and any Award Agreement applicable to the Participant, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Committee. If the Participant is married and resides in a community property state, a designation of a person other than the Participant's spouse as his beneficiary with respect to more than 50% of the Participant's interest in the Award shall not be effective without the prior written consent of the Participant's spouse. If no beneficiary has been designated or survives the Participant, payment shall be made to the person entitled thereto pursuant to the Participant's will or the laws of descent and distribution. Subject to the foregoing, a beneficiary designation may be changed or revoked by a Participant at any time provided the change or revocation is provided to the Company.
             14.4      STOCK CERTIFICATES .    Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates evidencing shares of Stock pursuant to the exercise of any Award, unless and until the Board has determined, with advice of counsel, that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange or quotation system on which the shares of Stock are listed, quoted or traded. All Stock certificates delivered pursuant to the Plan are subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with Federal, state, or foreign jurisdiction, securities or other laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the Stock is listed, quoted, or traded. The Committee may place legends on any Stock certificate to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Board may require that a Participant make such reasonable covenants, agreements, and representations, as the Board deems advisable in order to comply with any such laws, regulations, or requirements.
             14.5      DEFERRAL PURSUANT TO DEFERRED COMPENSATION PLAN .    The Award Agreement for any Award other than an Option or Restricted Stock Award may allow the Participant to defer receipt of any compensation attributable to the Award pursuant to the terms and provisions of the Deferred Compensation Plan of 2005 for Employees of Pinnacle West Capital Corporation and Affiliates or any successor or other nonqualified deferred compensation plan. Any such Award Agreement shall comply with the requirements of Section 409A of the Code.
             14.6      CLAWBACK .    Notwithstanding any provision of the Plan to the contrary, in an Award Agreement, the Committee shall include provisions calling for the recapture or clawback of all or any portion of an Award to the extent necessary to comply with applicable law in effect on the date of the Award Agreement, including, but not limited to, the final rules issued by the Securities and Exchange Commission and the New York Stock Exchange pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Committee also may include other clawback provisions in the Award Agreement as it determines to be appropriate. By accepting an Award, each Participant agrees to be bound by, and comply with, the terms of any such recapture or clawback provisions and with any Company request or demand for recapture or clawback.

CHANGE OF CONTROL
             15.1      GENERAL RULE .    Unless the Committee with the approval of the Board provides otherwise in an Award Agreement, if a Change of Control occurs, immediately prior to the Change of Control:
                         (a)       Any and all Options and SARs granted hereunder shall become exercisable immediately before the closing of the transaction that will result in the Change of Control and all necessary steps shall be taken to allow the Participants to immediately exercise such Options or SARs so that any Stock issued upon such exercise shall be able to participate in the transaction that results in the Change of Control. If pursuant to the terms of the Award Agreement, an SAR is to be paid in cash, the SAR will be deemed to be exercised on the closing of the transaction that results in the Change of Control. The cash payment then will be made within ten days following the closing of the transaction that results in the Change of Control.
                         (b)       Any time based or other restrictions imposed on Restricted Stock or Restricted Stock Units shall lapse. All Restricted Stock Units and Stock Units shall become immediately payable and shall be paid in Stock or cash, in accordance with the terms of the applicable Award Agreement. All necessary steps shall be taken to allow any Stock issued in payment for the Restricted Stock Units or Stock Units (and any shares of Restricted Stock that become unrestricted) to participate in the transaction that results in the Change of Control. If pursuant to the terms of the Award Agreement, a Restricted Stock Unit is to be paid in cash, the Restricted Stock Unit will be settled as of the closing of the transaction that results in the Change of Control and the cash payment then will be made within ten days following the closing of the transaction that results in the Change of Control.
                         (c)       Any Awards of Performance Shares or Performance Share Units that are payable in Stock shall be converted to Stock Grants, which shall be immediately vested. All Stock payable in connection with the Stock Grant shall be issued immediately before the closing of the transaction that will result in the Change of Control and all necessary steps shall be taken to allow any Stock so issued to participate in the transaction that result in the Change of Control. In converting Performance Shares or Performance Share Units to a Stock Grant, the Participants shall receive the number of shares of Stock that would have been earned at the target level of performance; provided, however, that if, in the judgment of the Committee, the level of performance as of the last day of the month that is at least 30 days prior to the closing of the transaction that results in the Change of Control is reasonably ascertainable and such performance exceeds the target level of performance, the Participants shall receive the number of shares of Stock that would have been earned at such attained level of performance rather than the target level of performance. Whether the attained level of performance exceeds the target level will be determined on a goal-by-goal basis. For example, if four equally weighted goals are established in connection with a particular Award, and the attained level of performance exceeds the target level for one of such goals, 25% of the Award will be earned at the attained level and the remaining 75% will be earned at the target level.
                         (d)       Any Awards of Performance Share Units that are payable in cash shall become immediately vested. The Participants then shall receive a cash payment equal to the Fair Market Value of the specified number of shares of Stock payable pursuant to the Award at the target level of performance; provided, however, that if, in the judgment of the Committee, the level of performance as of the last day of the month that is at least 30 days prior to the closing of the transaction that results in the Change of Control is reasonably ascertainable and such performance exceeds the target level of performance, such attained level of performance shall be used. Whether the attained level of performance exceeds the target level will be determined on a goal-by-goal basis as further described in Section 15.1(c) . The cash payment then will be made within ten days following the closing of the transaction that results in the Change of Control.
A-15

Table of Contents
                               (e)           Performance Cash Awards shall be deemed to be satisfied and earned at the target level of performance; provided, however, that if, in the judgment of the Committee, the level of performance as of the last day of the month that is at least 30 days prior to the closing of the transaction that results in the Change of Control is reasonably ascertainable and such level and such performance exceeds the target level of performance, such attained level of performance shall be used. Whether the attained level of performance exceeds the target level will be determined on a goal-by-goal basis as further described in Section 15.1(c) . Performance Cash Awards then shall be paid within ten days following the closing of the transaction that results in the Change of Control.
                               (f)            Any Dividend Equivalent Awards shall be paid in cash or Stock as determined in accordance with the applicable Award Agreement. All Stock payable in connection with the Dividend Equivalent shall be issued immediately before the closing of the transaction that will result in the Change of Control and all necessary steps shall be taken to allow any Stock so issued to participate in the transaction that result in the Change of Control. Any cash payment shall be made within ten days following the closing of the transaction that results in the Change of Control.
                               (g)           With respect to an Award that the Company concludes is subject to Section 409A of the Code, a Change of Control may not result in the acceleration of the timing of any payment unless the transaction that results in the Change of Control also constitutes a "change of control event" as such term is used in Treasury Regulation Section 1.409A-3(i)(5). Such transaction shall be considered to be a Change of Control for all other purposes of such an Award, however, unless prohibited by regulations issued pursuant to Section 409A. For example, such transaction will result in the lapse of any time based or other restrictions on a Restricted Stock or Restricted Stock Unit Award. If due to the above provisions the payment of an Award may not be accelerated, the Board, prior to the Change of Control, shall take such action as it in good faith determines to be necessary to assure that there will be no material impairment to either the value of the Award to the Participant or the Participant's opportunity for future appreciation in respect of such Award.
             15.2             BOARD OVERRIDE .    Notwithstanding the foregoing provisions of Section 15.1 , the Board, prior to a Change of Control, may determine that no Change of Control shall be deemed to have occurred or that some or all of the enhancements to the rights of Participants under all or a portion of the outstanding Awards upon a Change of Control, as provided under Section 15.1 or the Award Agreement, shall not apply to specified Awards. The Board may exercise such override authority only if, before or immediately upon the occurrence of the specified event that would otherwise constitute a Change of Control, the Board, as constituted prior to the Change of Control, reasonably concludes, in good faith, that: (i) Participants holding Awards affected by action of the Board under this Section 15.2 shall be protected by legally binding obligations of the Company or the surviving entity or the parent thereof because such Awards (A) shall remain outstanding following consummation of all transactions involved in or contemplated by such Change of Control or (B) shall be assumed and adjusted by the surviving entity resulting from such transactions or the parent thereof, or (C) shall be exchanged for new awards issued by the surviving entity resulting from such transaction or the parent thereof; and (ii) changes in the terms of the Award resulting from such transactions will not materially impair the value of the Awards to the Participants or their opportunity for future appreciation in respect of such Awards. The Board may exercise such override authority with respect to an Award which the Company concludes is subject to (and not excepted from) the requirements of Section 409A of the Code only in a manner and to the extent permissible under Section 409A.
             15.3             PARTICIPANT CONSENT NOT REQUIRED .    Nothing in this Article 15 or any other provision of this Plan is intended to provide any Participant with any right to consent to or object to any transaction that might result in a Change of Control and each provision of this Plan shall be interpreted in a manner consistent with this intent. Similarly, nothing in this Article 15 or any other provision of this Plan is intended to provide any Participant with any right to consent to or object to any action taken by the Board pursuant to Section 15.2 .

With the Committee's consent as expressed in an Award Agreement or in any policy adopted by the Committee, the Company may permit the Participant to satisfy a tax withholding requirement by (a) directing the

Company to withhold shares of Stock to which the Participant is entitled pursuant to the Award in an amount necessary to satisfy the Company's applicable federal, state, local or foreign income and employment tax withholding obligations with respect to such Participant, (b) tendering previously-owned shares of Stock held by the Participant for six months or longer to satisfy the Company's applicable federal, state, local, or foreign income and employment tax withholding obligations with respect to the Participant, (c) a broker-assisted "cashless" transaction, or (d) personal check or other cash equivalent acceptable to the Company.

With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Company or any Affiliate. Neither the Participant nor any other persons shall have any interest in any fund or in any specific asset or assets of the Company or any other entity by reason of any Award, except to the extent provided hereunder.
             17.6             RELATIONSHIP TO OTHER BENEFITS .    No payment pursuant to the Plan shall be taken into account in determining any benefits pursuant to any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Affiliate, except as otherwise provided in such plan.

             17.8             TITLES AND HEADINGS .    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.

Notwithstanding any other provision of the Plan, the Committee may impose such conditions on the exercise of any Award as may be required to satisfy the requirements of Rule 16b-3 or its successors pursuant to the Securities Exchange Act.

If the shares paid pursuant to the Plan may in certain circumstances be exempt from registration pursuant to the Securities Act of 1933, as amended, the Company may restrict the transfer of such shares in such manner as it deems advisable to ensure the availability of any such exemption. The Committee shall impose such restrictions on any Award as it may deem advisable, including without limitation, restrictions under applicable federal securities law, under the requirements

             17.14             SURVIVAL OF PROVISIONS .    The rights, remedies, agreements, obligations and covenants contained in or made pursuant to this Plan, any Award Agreements and any notices or agreements made in connection with this Plan shall survive the execution and delivery of such notices and agreements and the delivery and receipt of such shares of Stock.
             17.15             COMPLIANCE WITH SECTION 409A .    
                                 (a)             General Compliance .    Some of the types of Awards that may be granted pursuant to the Plan (including, but not necessarily limited to, Restricted Stock Unit Awards, Performance Share Awards, Performance Share Unit Awards, Performance Cash Awards and Stock Unit Awards) may be considered to be "non-qualified deferred compensation" subject to the requirements of Section 409A of the Code. If an Award is subject to the requirements of Section 409A of the Code, the Company intends (but cannot and does not guarantee) that the Award Agreement and this Plan comply fully with and meet all of the requirements of Section 409A of the Code or an exception thereto and the Award Agreement shall include such provisions, in addition to the provisions of this Plan, as may be necessary to assure compliance with Section 409A of the Code or an exception thereto. An Award subject to Section 409A of the Code also shall be administered in good faith compliance with the provisions of Section 409A of the Code as well as applicable guidance issued by the Internal Revenue Service and the Department of Treasury. To the extent necessary to comply with Section 409A of the Code, any Award that is subject to Section 409A of the Code may be modified, replaced or terminated by the Committee. Notwithstanding any provision of this Plan or any Award Agreement to the contrary, in the event that the Committee determines that any Award is or may become subject to Section 409A of the Code, the Company may adopt such amendments to the Plan and the related Award Agreements, without the consent of the Participant, or adopt other policies and procedures (including amendments, policies and procedures with retroactive effective dates), or take any other action that the Committee determines to be necessary or appropriate to either comply with Section 409A of the Code or to exclude or exempt the Plan or any Award from the requirements of Section 409A of the Code.
                                 (b)             Delay for Specified Employees .    If, at the time of a Participant's Separation from Service, the Company has any Stock which is publicly traded on an established securities market or otherwise, and if the Participant is considered to be a Specified Employee, to the extent any payment for any Award is subject to the requirements of Section 409A of the Code and is payable upon the Participant's Separation from Service, such payment shall not commence prior to the first business day following the date which is six months after the Participant's Separation from Service (or if earlier than the end of the six-month period, the date of the Participant's death). Any amounts that would have been distributed during such six-month period will be distributed on the day following the expiration of the six-month period.
                                 (c)             Prohibition on Acceleration or Deferral .    Under no circumstances may the time or schedule of any payment for any Award that is subject to the requirements of Section 409A of

In addition, in the event of a dispute with respect to any payment, such payment may be delayed in accordance with the regulations and other guidance issued pursuant to Section 409A of the Code.
