SAFE HARBOR AND NON-GAAP MEASURES

This document contains forward-looking information that involves risks and uncertainties, that include, but are not limited to: state and federal regulatory and legislative decisions and actions; regional economic and market conditions which could affect customer growth and energy usage; weather variations affecting energy usage; the cost of debt and equity capital and access to capital markets; the performance of the stock market and changing interest rate environment, which affect the value of the company’s pension and other postretirement benefit plan assets and the related contribution requirements and expense; unexpected increases in O&M expense; resolution of pending litigation matters; changes in accounting standards; changes in critical accounting estimates; the ongoing restructuring of the electric industry; changes to long-term contracts; the cost of fuel and power supplies; performance of TEP’s generating plants; and other factors listed in UniSource Energy’s Form 10-K and 10-Q filings with the Securities and Exchange Commission. The preceding factors may cause future results to differ materially from historical results or from outcomes currently expected by UniSource Energy.

The Company’s press releases and other communications may include certain non-Generally Accepted Accounting Principles (GAAP) financial measures. A “non-GAAP financial measure” is defined as a numerical measure of a company’s financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in the Company’s financial statements.

Non-GAAP financial measures utilized by the Company include presentations of revenues, operating expenses, operating income and earnings (loss) per share. The Company uses these non-GAAP measures to evaluate the operations of the Company. Certain non-GAAP financial measures utilized by the Company exclude: the impact of non-recurring items: the effect of accounting changes or adjustments; expenses that are reimbursed by third parties; and other items. The Company’s management believes that these non-GAAP financial measures provide useful information to investors by removing the effect of variances in GAAP reported results of operations that are not indicative of fundamental changes in the earnings or cash flow capacity of the Company’s operations. Management also believes that the presentation of the non-GAAP financial measures is largely consistent with its past practice, as well as industry practice in general, and will enable investors and analysts to compare current non-GAAP measures with non-GAAP measures with respect to prior periods.

NON-GAAP MEASURES

Utility Gross Margin — TEP

TEP’s Utility Gross Margin represents retail and wholesale electric revenues less fuel and purchased power expense. Utility Gross Margin is presented here as a measure of operating performance because it can be used as an indication of a company’s electric revenues in excess of the fuel and purchased power costs and is commonly used as an analytical indicator in our industry. Utility Gross Margin measures presented may not be comparable to similarly titled measures used by other companies. Utility Gross Margin is not a measurement presented in accordance with United States generally accepted accounting principles (GAAP), and we do not intend Utility Gross Margin to represent operating income as defined by GAAP. Utility Gross Margin should not be considered to be an alternative to operating income or any other items calculated in accordance with GAAP or an indicator of our operating performance.

TEP believes Utility Gross Margin, which is a non-GAAP financial measure, provides useful information to investors as a measure of operating performance. The most directly comparable GAAP measure to Utility Gross Margin is operating income.

Base O&M — TEP

Base O&M excludes: expenses incurred by TEP that are reimbursed by a third party; and the sale of SO₂ allowances, which is recorded as a contra expense on TEP’s GAAP financial statements. Base O&M is not a measurement presented in accordance with GAAP and we do not intend Base O&M to represent reported O&M as defined by GAAP. You should not consider Base O&M to be an alternative to O&M or any other items calculated in accordance with GAAP. We believe Base O&M, which is a non-GAAP measure, provides useful information to investors as a measure of TEP’s operating and maintenance expenses.

For the year ended December 31, 2008, 4 million potentially dilutive shares from the conversion of convertible senior notes, and after-tax interest expense of $4.4 million was not included in the computation of diluted EPS because to do so would be anti-dilutive.

Stock options with an exercise price greater than the average market price of the common stock at year end are excluded from the dilution calculation.
