Box 711 Tucson, Arizona 85702 (520) 571-4000 Notice of Annual Meeting of Shareholders May 21, 1999 To the Shareholders of UNISOURCE ENERGY CORPORATION Notice is hereby given that the Annual Meeting of Shareholders (the "Meeting") of UniSource Energy Corporation ("UniSource Energy") will be held on the 21st day of May, 1999, at the Leo Rich Theater, 260 South Church Avenue, Tucson, Arizona at 10:00 a.m., Tucson time, for the purposes of: (1) electing a Board of Directors for the ensuing year; and (2) transacting such other business as may properly come before the Meeting or any adjournment or adjournments thereof. The holders of record of common stock at the close of business on March 12, 1999 will be entitled to vote at the Meeting and at any adjournments thereof. Proxy soliciting material is first being sent or given to shareholders on March 30, 1999. By order of the Board of Directors, Dennis R. Nelson Corporate Secretary Dated: March 30, 1999 IMPORTANT: Your presence at the Meeting is desired, but if you cannot be present, please fill out, sign, date, and return the enclosed form of proxy in the envelope provided. Due to the number of shareholders, your cooperation in returning your proxy promptly is essential and will be very much appreciated. YOUR VOTE IS IMPORTANT, REGARDLESS OF HOW MANY SHARES YOU OWN. TO VOTE YOUR SHARES, PLEASE MARK, SIGN, AND DATE THE ENCLOSED PROXY AND MAIL IT PROMPTLY IN THE ENCLOSED RETURN ENVELOPE. PROXY STATEMENT General - - ------- This Proxy Statement is being mailed to shareholders in connection with the solicitation, by and on behalf of the Board of Directors of UniSource Energy Corporation ("UniSource Energy"), of proxies to be voted at the Annual Meeting of Shareholders (the "Meeting") of UniSource Energy to be held on May 21, 1999, at the time and place and for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders, and at any and all adjournments of the Meeting. An appropriate form of proxy for execution by shareholders is enclosed. Any shareholder giving a proxy has the right to revoke the same by giving notice to UniSource Energy in writing, directed to the Corporate Secretary, or in person at the Meeting at any time before the proxy is exercised. UniSource Energy will bear the entire cost of the solicitation of proxies. UniSource Energy will make solicitations primarily by mail. Additional solicitation of brokers, banks, nominees, and institutional investors may be made pursuant to a special engagement of Beacon Hill Partners, Inc. at a cost to UniSource Energy of approximately $3,500 plus reasonable out-of-pocket expenses not to exceed $1,500. If necessary to obtain reasonable representation of shareholders at the Meeting, solicitations may also be made by telephone, facsimile, or personal interview. UniSource Energy will request brokers or other persons holding stock in their names, or in the names of their nominees, to forward proxy material to the beneficial owners of such stock or request authority for the execution of the proxies, and will reimburse such brokers or other persons for their expense in so doing. In accordance with UniSource Energy's Bylaws, the Board of Directors has fixed March 12, 1999 as the record date (the "Record Date") for the determination of shareholders entitled to vote at the Meeting and at any and all adjournments thereof. The stock transfer books will not be closed. Change in Accountants - - --------------------- On November 7, 1997, based upon the recommendation of its audit committee, the Board of Directors of UniSource Energy voted to appoint PricewaterhouseCoopers, LLP as UniSource Energy's independent accountants effective for the year ending December 31, 1998. UniSource Energy chose not to renew the engagement of Deloitte & Touche LLP, UniSource Energy's then present independent accountants. Deloitte & Touche LLP continued to serve for the 1997 fiscal year, including rendering an opinion on UniSource Energy's financial statements for the year ended December 31, 1997. The reports of Deloitte & Touche LLP on UniSource Energy's financial statements for each of the two most recent years ended December 31, 1997 did not contain any adverse opinion or disclaimer of opinion, nor were the reports qualified in any matter. During 1996, 1997 and the period from December 31, 1997 to March 2, 1998, the date of UniSource Energy's Annual Report on Form 10-K for the year ended December 31, 1997, there were no disagreements with Deloitte & Touche LLP on any matter of accounting principle or practice, financial statement disclosure or auditing scope or procedure. During this period, there were no "reportable events" as that term is defined in Item 304 (a)(1)(v) of Regulation S-K. Deloitte & Touche LLP furnished a letter addressed to the Securities and Exchange Commission ("SEC") stating that it agreed with the above statements for the two most recent years ended December 31, 1997 to March 2, 1998, the date of UniSource Energy's Annual Report on Form 10-K for the year ended December 31, 1997. On November 14, 1997, UniSource Energy engaged PricewaterhouseCoopers, LLP as its principal accountants to audit its financial statements for the year ending December 31, 1998. During 1996, 1997 and the period from December 31, 1997 to March 2, 1998, the date of UniSource Energy's Annual Report on Form 10-K for the year ended December 31, 1997, UniSource Energy did not consult PricewaterhouseCoopers, LLP on items which concerned the application of accounting principles generally, or to a specific transaction or group of transactions, either completed or proposed, or the type of audit opinion that might be rendered on the financial statements except as related to transactions for the year ending December 31, 1998. Representatives of PricewaterhouseCoopers, LLP, UniSource Energy's current independent auditors, are expected to be present at the Meeting with the opportunity to make a statement if they desire to do so, and to be available to respond to appropriate questions. Representatives of Deloitte & Touche LLP are not expected to be present at the meeting. Voting of Shares - - ---------------- At the Record Date, UniSource Energy had outstanding 32,294,598 shares of common stock, no par value ("Common Stock"). At the Record Date, there were 25,219 shareholders of record of the Common Stock. Holders of Common Stock will be entitled to one vote per share, subject to cumulative voting rights in the election of Directors as described below. Under the Arizona Business Corporation Act, a majority of the shares entitled to vote on any single subject matter which may be brought before the Meeting will constitute a quorum, and business may be conducted once a quorum is represented at the Meeting. Except as otherwise specified by law, if a quorum exists, action on a matter other than the election of Directors will be deemed approved if the votes cast "For" such matter exceed votes cast "Against" it. In the election of Directors, each holder of shares of Common Stock has the right to cumulate his votes by casting as many votes in the aggregate equal to the number of his shares of Common Stock multiplied by the number of Directors to be elected. He may cast the whole number of such votes for one nominee or distribute such votes among two or more nominees. If a quorum is present, Directors are elected by a plurality of the votes cast by the shares entitled to vote. Withheld votes will be counted as being represented at the Meeting for quorum purposes but will not have an effect on the vote. The shares represented by an executed proxy will be voted for the election of Directors, or withheld in accordance with the specifications in the proxy. If no specification is made in the proxy, the proxy will be voted "FOR" the nominees listed herein. Any broker "non-votes" with respect to a proposal will be counted for purposes of determining the presence or absence of quorum, but will not be counted as shares represented and voting on that proposal. In contrast, proxies voted "abstain" will have the same legal effect as votes against a proposal.

(2) In a statement dated February 1, 1999, filed with the SEC on Schedule 13G under the Securities Exchange Act of 1934, as amended, The Prudential Insurance Company of America indicated it may have direct or indirect voting and/or investment discretion over 1,786,720 shares of the outstanding Common Stock of UniSource Energy which are held for the benefit of its clients by its separate accounts, externally managed accounts, registered investment companies, subsidiaries and/or other affiliates. Section 16(a) Beneficial Ownership Reporting Compliance - - ------------------------------------------------------- Section 16(a) of the Securities and Exchange Act of 1934, as amended, and SEC regulations require Directors, certain officers, and persons who own greater than 10% of the stock of UniSource Energy to file reports of ownership and changes in ownership of such UniSource Energy stock with the SEC and New York Stock Exchange. These Directors, officers and greater than 10% beneficial owners are required by law to furnish UniSource Energy with copies of all Section 16(a) forms they file. Based solely on a review of the copies of such forms furnished to UniSource Energy and on written representations of its Directors and officers, UniSource Energy believes that all Section 16(a) filing requirements applicable to its Directors and officers were complied with during 1998, with the exception of Mr. Jose L. Canchola, a Director of UniSource Energy who inadvertently failed to timely file a Form 4 for the single acquisition of 1,000 shares of Common Stock he purchased during 1998, Ms. Elizabeth T. Bilby, a Director of UniSource Energy who inadvertently failed to timely file a Form 4 for the single acquisition of 100 shares of Common Stock she purchased during 1998, and Mr. Daniel W. L.

Glaser -- -- -- -- -- On June 26, 1997, at the recommendation of the Compensation Committee, the Board of Directors unanimously approved a Performance Share Program under the TEP 1994 Omnibus Stock and Incentive Plan (the "Omnibus Plan"). The Performance Share Program is intended to align the interests of UniSource Energy's officers directly with the interest of its shareholders. On October 10, 1997, the Compensation Committee approved a total of 254,540 performance shares to be awarded (the "Target Number of Shares") to all executive officers, including Mr. Pignatelli and the Named Executives. The Performance Share Program provides for the delivery of shares of UniSource Energy's Common Stock equal to 0 to 150% of the Target Number of Shares, depending upon UniSource Energy's total shareholder return (stock price increase plus dividends, divided by the initial stock price) over the performance period ending December 31, 2001, compared to corporations in a peer group. For this purpose, "peer group" means those corporations that, as of the vesting date, are included in the S&P Electric Utility Index. At the end of the performance period, the Compensation Committee will determine the number of performance shares that vest (the "Vested Performance Shares") based on UniSource Energy's performance against the peer group. Performance share recipients will receive one share of Common Stock for each Vested Performance Share. The shares of Common Stock underlying the performance shares are subject to limitations on their sale, transfer, or pledge prior to the time they become vested. Recipients of performance shares will have no rights as stockholders of UniSource Energy, including dividend rights and voting rights, with respect to the performance shares and any shares of Common Stock underlying or issuable in respect of such performance shares until such shares are actually issued and held of record by the recipient.

Refer to the Summary Compensation Table for information concerning their compensation. (2) Cash compensation includes amounts earned but deferred at the election of Directors. (3) These are grants of UniSource Energy Common Stock options under the 1994 Outside Director Stock Option Plan (the "Plan"), which vest in one-third increments on the grant date anniversary and expire in ten years. Except for Dr. Bickle, Mr. Burlingame and Mr. Fessler, options were granted to each of the Directors on January 3, 1998, at an exercise price of $18.1250, the market value of the underlying stock on the grant date. Dr. Bickle and Mr. Burlingame joined the board in March 1998 and were granted their options on March 6, 1998 at an exercise price of $16.7813, the market value of the underlying Common Stock on the grant date. Mr. Fessler joined the board in May 1998, and was granted his options under the Plan on May 8, 1998 at an exercise price of $17.1250, the market value of the underlying stock on the grant date. Each Director of UniSource Energy, other than Mr. Pignatelli, Mr. Adler and Mr. Bayless, received an annual cash retainer of $17,500, $1,000 for each Board meeting, $1,000 for each committee meeting and $1,500 as chairperson for each committee meeting attended in 1998. The annual retainer amount paid to Dr. Bickle, Mr. Burlingame and Mr. Fessler was prorated because they were each appointed to the Board during 1998 and served less than the entire year. The annual retainer amount paid to Mr. Shropshire was prorated because he retired from the Board effective May 8, 1998 and thus served less than the entire year. OFFICER CHANGE IN CONTROL AGREEMENTS TEP has Change in Control Agreements ("Agreements") with fourteen officers (including Mr. Pignatelli, Mr. Adler, Mr. Nelson and Mr. Glaser) which became effective as of December 4, 1998 and remain in effect until the latter of: (1) five years after the date either TEP or the officer gives written notice of termination; or (2) if a change in control occurs during the term of the Agreement, five years after the change of control. For the purpose of the Agreements, a change in control includes the acquisition of beneficial ownership of 30% of the Common Stock, certain changes in the Board of Directors, approval by the shareholders of certain mergers or consolidations, or certain transfers of the assets of UniSource Energy. The Agreements provide that each officer shall be employed by TEP or one of its subsidiaries or affiliates in a position comparable to their current position, with compensation and benefits which, as set forth in each Agreement, are at least equal to such officer's then current compensation and benefits, for an employment period of five years after a change in control occurs (subject to earlier termination due to such officer's acceptance of a position with another company or termination for cause). Following a change in control, in the event that the officer's employment is terminated by TEP (with the exception of termination due to the officer's acceptance of another position or for cause), or if the officer terminates his employment because of a reduction in position, responsibility, salary or for certain other stated reasons, the officer is entitled to severance benefits in the form of: (i) a lump sum payment equal to three times the present value of his salary and bonus compensation; (ii) the present value of the additional amount he would have received under the TEP Retirement Plan if he had continued to be employed for the five-year period after a change in control occurs; (iii) the present value of contributions that would have been made by TEP under the TIP if he had continued to be employed for such five-year period; and (iv) the present value of any employee awards under the Omnibus Plan or any successor plan, which are outstanding at the time of the officer's termination (whether vested or not), prorated based on length of service. Such officer is also entitled to continue to participate in TEP's health, death benefit and disability benefit plans for five years after the termination. The Agreements further provide that TEP will make a payment to the officer to offset any excise taxes that may become payable by the officer by reason of application of Sections 280G and 4999 of the Code, and any associated federal, state, local, employment and or excise tax owed on this gross-up payment. Any payments by UniSource Energy which are subject to Section 280G of the Code are not deductible. Assuming a change in control occurred on the Record Date which resulted in the immediate termination of the Chief Executive Officer and the three Named Executives with whom TEP has Agreements, the total payments made by UniSource Energy pursuant to the Agreements would not be expected to exceed $13.2 million. REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION The Compensation Committee of the Board of Directors (the "Compensation Committee") is responsible for developing and administering UniSource Energy's executive compensation policies and programs and making recommendations to the Board of Directors with respect thereto. In 1998, the Compensation Committee was comprised of six of UniSource Energy's independent outside Directors. Dr. Bickle and Mr. Burlingame were appointed to the Compensation Committee in May 1998 replacing Mr. Donald G. Shropshire, who retired in May. The Compensation Committee determines the compensation of UniSource Energy's executive officers, including Mr. Pignatelli and the Named Executives, and sets policies for and reviews the compensation awarded to other key members of management. UniSource Energy applies a consistent philosophy to compensation for all executive employees, including the Named Executives. Compensation Policies Applicable to Executive Officers ------------------------------------------------------ UniSource Energy's executive compensation policies and programs generally are intended to (i) relate the compensation of employees to the success of UniSource Energy and the creation of shareholder value; and (ii) attract, motivate and retain highly qualified executives. UniSource Energy's compensation program was developed with the assistance of an external consultant, and is intended to provide competitive pay levels which are linked to the achievement of UniSource Energy's strategic objectives. UniSource Energy's 1998 compensation program consisted of three components: (i) base salary; (ii) short-term incentive compensation; and (iii) long-term incentive compensation. Base Salaries - - ------------- The base salary component of compensation is intended to be competitive with that paid by companies with which UniSource Energy competes for employees. In developing the compensation program, the Compensation Committee retained an external consultant to conduct a competitive analysis of pay for UniSource Energy's officer group. In conducting its analysis for 1998, the consultant used comparative groups of utility (primarily electric) industry as well as general industry companies with revenues similar to UniSource Energy, chosen based on their business and size. The utility industry group served as an industry comparator group for top-level personnel, and the general industry group was used as a comparator based on the Compensation Committee's belief that UniSource Energy's market for top-level personnel extends beyond the utility industry. The Compensation Committee believes the companies in the comparative group are a more appropriate comparison for UniSource Energy than the Edison Electric 100 companies used in the performance graph set forth following this Report, because the type of business and annual revenues of the companies included in the survey are more closely related to those of UniSource Energy and the companies in the comparative group represent primary competitors to UniSource Energy for top-level management personnel. The external data from companies in the comparative group was used to develop a competitive compensation for each executive position. Base salaries for UniSource Energy's executive officers (including Mr. Bayless, Mr. Pignatelli and the Named Executives) were set at market compensation levels in January 1998, in recognition of the increasingly competitive environment in the electric industry and the need to continue to attract and retain highly qualified executives, as well as the fact that a substantial portion of each executive's total compensation package is "at-risk," based on the achievement of certain corporate goals. See Short-Term Incentive Compensation and Long-Term Incentive Compensation below. Mr. Bayless resigned as Chairman, President and Chief Executive Officer in July 1998. Mr. Pignatelli was named Chairman, President and Chief Executive Officer at that time. His base salary was determined based on the aforementioned competitive pay analysis of pay for UniSource Energy's officer group. Mr. Bayless received a 4% increase in base salary for 1998. The Named Executives received increases ranging from 4% to 13%. Short-Term Incentive Compensation - - --------------------------------- The Board of Directors adopted the Short-Term Incentive Plan to provide compensation for meeting or exceeding specified corporate objectives designed to contribute to the attainment of UniSource Energy's long-term strategic plan. Under the Short-Term Incentive Plan, target award levels are set as a percentage of each participant's base salary. In 1998, the percentage for Mr. Pignatelli was 40% and for the other executive officers ranged from 25 to 30%. Actual awards can vary from 0 to 200% of the target award level, depending upon UniSource Energy's performance in relation to pre-established goals. For 1998, pre-established goals for officers (including Mr. Pignatelli and the Named Executives) consisted of two corporate objectives and a customer service multiplier. The corporate objectives consisted of: (i) increasing UniSource Energy's intrinsic value, measured by cash flow return on investment; and (ii) improving profitability and cost management, measured by operations & maintenance expenses per kilowatt hour sold. The customer service multiplier consisted of eight component goals, relating to: (i) reducing the number of outages; (ii) decreasing average outage duration; (iii) improving customer service satisfaction; (iv) increasing customer use of special programs and services; (v) increasing services provided to customers; (vi) increasing customer service options; (vii) sustaining air quality compliance; and (viii) sustaining Company visibility through participation in community activities. In calculating the percentage of target awards payable, the Compensation Committee established target performance levels for each of the corporate objectives. Minimum performance levels (50% of target awards payable) and exceptional performance levels (150% of target awards payable) were established as well. No credit was given for performance below minimum levels. The customer service multiplier was established at levels ranging from 0.8 to 1.2, depending upon the number of component goals met. In order for any incentive compensation to be paid, UniSource Energy was required to meet at least the minimum performance levels on each of the corporate objectives. Based on the achievement of corporate objectives for 1998, incentive compensation was paid in the amount of 120% of target award levels to Mr. Pignatelli and the Named Executives. Mr. Bayless did not receive incentive compensation for 1998. Incentive compensation earned in 1998 by Mr. Pignatelli and the Named Executives is set forth in the preceding Summary Compensation Table. Long-Term Incentive Compensation - - -------------------------------- UniSource Energy's long-term incentive compensation is intended to attract and retain quality employees over the long term in a manner that directly aligns them with shareholder interests. At the recommendation of the Compensation Committee, the Board of Directors unanimously adopted, and, at the 1994 Annual Meeting of Shareholders, the shareholders approved, the Omnibus Plan. On July 9, 1998, the Compensation Committee issued Incentive Stock Options ("ISOs") and Non-Qualified Stock Options ("NQSOs") to all executive officers of UniSource Energy including Mr. Pignatelli and the Named Executives. In calculating the level of awards to Mr. Pignatelli and the other executive officers, the Compensation Committee considered the aforementioned analysis of executive compensation for comparative companies. Based on such analysis, the Compensation Committee awarded Mr. Pignatelli ISOs and NQSOs with a total value equal to 60% of his base salary (based on a Black-Scholes pricing model which assigned a value of $6.79 per share for ISOs and $5.91 per share for NQSOs). The total value of stock options issued to the Named Executives ranged from 30% to 33% of base salary. The number of shares covered by the stock option grant to Mr. Pignatelli was 58,246. The Compensation Committee did not consider the number of options previously granted or outstanding. On June 26, 1997, at the recommendation of the Compensation Committee, the Board of Directors unanimously approved a Performance Share Program under the Omnibus Plan. The Performance Share Program is intended to align the interests of UniSource Energy's executive officers directly with the interest of its shareholders. The Performance Share Program provides for the delivery of shares of UniSource Energy's Common Stock equal to 0 to 150% of the Target Number of Shares, depending upon UniSource Energy's total shareholder return (stock price increase plus dividends, divided by the initial stock price) over the performance period ending December 31, 2001, compared to corporations in a peer group. For this purpose, "peer group" means those corporations that as of the vesting date are included in the S&P Electric Utility Index. At the end of the performance period, the Compensation Committee will determine the number of Vested Performance Shares based on UniSource Energy's performance against the peer group. Performance share recipients will receive one share of Common Stock for each Vested Performance Share. The shares of Common Stock underlying the performance shares are subject to limitations on their sale, transfer, or pledge prior to the time they become vested. Recipients of performance shares will have no rights as stockholders of UniSource Energy, including dividend rights and voting rights, with respect to the performance shares and any shares of Common Stock underlying or issuable in respect of such performance shares until such shares are actually issued and held of record by the recipient. On October 10, 1997, the Compensation Committee approved a total of 254,540 Target Number of Shares to all executive officers, including Mr. Bayless, Mr. Pignatelli and the other Named Executives. When he was named President and Chief Executive Officer in July 1998, Mr. Pignatelli's performance shares were increased by 80,000 to 104,790, representing a target value of approximately 200% of his base salary. The Compensation Committee does not presently have a policy regarding qualifying compensation paid to executive officers for deductibility under Section 162(m) of the Code.

TRANSACTION OF OTHER BUSINESS So far as UniSource Energy is aware, no matters other than those described in this Proxy Statement will be acted upon at the Meeting. If, however, any other matters shall properly come before the Meeting, it is the intention of the persons named in the enclosed proxy to vote the proxy in accordance with their judgment on such matters. SHAREHOLDER PROPOSALS FOR 2000 ANNUAL MEETING Rule 14a-4 of the SEC's proxy rules allows UniSource Energy to use discretionary voting authority to vote on a matter coming before an annual meeting of the shareholders which was not included in UniSource Energy's Proxy Statement (if UniSource Energy does not have notice of the matter at least 45 days before the date on which UniSource Energy first mailed its proxy materials for the prior year's annual meeting of the shareholders). In addition, discretionary voting authority may generally also be used if UniSource Energy receives timely notice of such matter (as described in the preceding sentence) and if, in the proxy statement, UniSource Energy describes the nature of such matter and how UniSource Energy intends to exercise its discretion to vote on such matter. Accordingly, for the 2000 Annual Meeting of Shareholders of UniSource Energy Corporation, any such notice must be submitted to the Corporate Secretary of UniSource Energy on or before February 14, 2000. This requirement is separate and apart from the SEC's requirements that a shareholder must meet in order to have a shareholder proposal included in the UniSource Energy Proxy Statement. Shareholder proposals intended to be presented at the 2000 Annual Meeting of Shareholders of UniSource Energy Corporation must be received by UniSource Energy no later than December 1, 1999 in order to be eligible for inclusion in UniSource Energy's Proxy Statement and the form of proxy relating to that meeting.
