ITEMS 2.02 AND 7.01 RESULTS OF OPERATIONS AND FINANCIAL CONDITION; REGULATION FD DISCLOSURE

Southern Union Company (the “Company”) today issued a press release reporting its second quarter 2008 results and announcing an investor call scheduled for 11 a.m. (ET) today to discuss those results. The Company is furnishing the press release, attached as Exhibit 99.1, pursuant to Item 2.02 and Item 7.01 of Form 8-K.

The press release contains earnings guidance affirming expected financial performance for the year ending December 31, 2008. The earnings guidance presented in the press release under Item 7.01 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.

In the attached presentation, the Company uses earnings before interest and taxes (EBIT) and adjusted EBIT, non-GAAP financial measures, as performance measures to evaluate Company and segment performance. As defined in Regulation G, "Conditions for Use of Non-GAAP Financial Measures," a non-GAAP financial measure is a numerical measure of a company's historical or future performance, financial position or cash flow that excludes (includes) amounts, or is subject to adjustments that have the effect of excluding (including) amounts, that are included (excluded) in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles (GAAP).

The Company defines EBIT as net earnings (loss) available for common shareholders, adjusted for: (i) items that do not impact earnings (loss) from continuing operations, such as extraordinary items, discontinued operations and the impact of accounting changes; (ii) income taxes; (iii) interest; (iv) dividends on preferred stock and (v) loss on extinguishment of preferred stock. EBIT may not be comparable to measures used by other companies. Additionally, EBIT should be considered in conjunction with net earnings and other performance measures such as operating income or operating cash flow.  In using adjusted EBIT, the Company takes into account mark to market unrealized hedging gain or loss.
