MILLENNIUM INVESTMENTS</b></u> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">On August 3, 2010, UniSource Energy was notified by the general partner of a private equity fund in which Millennium held an investment, that the fund’s investment in an unregulated energy company was fully impaired at June 30, 2010. The underlying investment related to a proposed Liquefied Natural Gas project which no longer appears viable. To recognize the impairment at June 30, 2010, we recorded a loss of $5 million before tax [$3 million after-tax] in the second quarter 2010. The loss is reflected in Other Expense on the UniSource Energy income statement. Millennium has no further investment obligation related to this fund. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">In June 2009, Millennium finalized a sale of its 50% equity interest in Carboelectrica Sabinas, S. de R.L. de C.V. (Sabinas), a Mexican limited liability company. Millennium received an upfront payment of $5 million in January 2009 and a $15 million, three-year, 6%, secured note receivable from Minerales de Monclova, S.A. de C.V. (Mimosa). Principal on the note is due at maturity; interest on the note is due annually on December 31. The $15 million note is included in Investments and Other Property — Other on UniSource Energy’s balance sheet. Millennium recorded a $6 million pre-tax gain on the sale included in Other Income on UniSource Energy’s income statement. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">In March 2010, Millennium sold its wholly-owned subsidiary Nations Energy Corporation.
