Exhibit 12.1

RATIO OF EARNINGS TO FIXED CHARGES

        The table below sets forth the Ratios of Earnings to Fixed Charges for us for the periods indicated. On October 26, 2006, we completed our initial public offering whereby we became the successor to the business of Eagle Rock Pipeline, L.P. For purposes of computing the ratios of earnings to fixed charges, earnings consist of income (loss) from continuing operations before adjustment for equity income from equity method investees, and our share of pretax losses of investees for which charges arising from guarantees are included in fixed charges, each as accounted for under the equity method, less capitalized interest, preference security dividend requirements of consolidated subsidiaries, and the non-controlling interest in pre-tax income of subsidiaries that have not incurred fixed charges. Fixed charges consist of the sum of interest expensed and capitalized, plus amortized premiums, discounts and capitalized expenses related to indebtedness, an estimated interest component of rental expense, and preference security dividend requirments of consolidated subsidiaries.
