        estimates of future market conditions, the behavior of other
        market participants and the actions of the Federal and State
        regulators.  Other factors include, but are not limited to,
        actions in the financial markets, weather conditions, economic
        conditions in the two companies' service territories,
        fluctuations in energy-related commodity prices, conversion
        activity, other marketing efforts and other uncertainties.  Other
        risk factors are detailed from time to time in the two companies'
        SEC reports.  Readers are cautioned not to place undue reliance
        on these forward-looking statements, which speak only as of the
