June 26, 2007

Core earnings is a non-GAAP financial measure that differs from earnings reported in accordance with GAAP.  We believe core earnings provide investors a meaningful indicator of our results that is
comparable among periods because it excludes the effects of discontinued operations, certain unusual items and mark-to-market gains and losses on energy contracts that may not be indicative of our
prospective earnings potential.  Core earnings is used internally to measure performance against budget and in reports for management and the Board of Directors.  Calculation of core earnings involves
judgments by management, including whether an item is classified as an unusual item, and our definition of core earnings may differ from similar terms used by other companies.  We are unable to
reconcile our core earnings guidance to GAAP earnings per share because we do not predict the future imp
act of unusual items and mark-to-market gains or losses on energy contracts.  The impact of
these items could be material to our operating results reported in accordance with GAAP.
