(1)  From a financial reporting perspective, we are the successor to Duke Energy
     Corporation's North American midstream natural gas business. The
     subsidiaries of Duke Energy that conducted this business were contributed
     to us in March 2000 immediately prior to the combination of these
     subsidiaries with the North American midstream natural gas business of
     Phillips Petroleum Company. For periods prior to the March 31, 2000
     combination, Duke Energy Field Services, LLC and these former subsidiaries
     of Duke Energy collectively are referred to as the "Predecessor Company."

(2)  Interest expense on a historical basis was primarily from intercompany
     debt. In addition, the historical advance accounts from the parent
     companies were non-interest bearing. As a result the historical capital
     structure is not indicative of the current capital structure.

     For purposes of calculating the ratios of earnings to fixed charges: (1)
"earnings" means income before extraordinary changes plus income taxes and fixed
charges, and (2) "fixed charges" include interest on indebtedness, amortization
of deferred financing costs, and that portion of lease expense that is deemed to
be representative of an interest factor. The ratio includes amounts from our
company, all of our majority-owned subsidiaries and our proportionate share of
distributed amounts from 50% owned investments accounted for using the equity
method.
