     discontinued operations.

     million for the years ended December 31, 2002 and 1998 and by $756 million
     for the six months ended June 30, 2003.

                 o    income or losses from equity investees, adjusted to
                      reflect actual distributions from equity investments; and

                 o    fixed charges;

less:

                 o    capitalized interest; and

                 o    preferred returns on consolidated subsidiaries.

Fixed charges means the sum of the following:

                 o    interest costs, not including interest on rate refunds;

                 o    amortization of debt costs;

                 o    that portion of rental expense which El Paso believes
                      represents an interest factor; and

                 o    preferred returns on consolidated subsidiaries.
