Forward-Looking  Statements:  Statements  in this  press  release  which are not
statements of historical fact are  forward-looking  statements  within the "safe
harbor" provision of the Private Securities Litigation Reform Act of 1995. These
forward-looking  statements are based on information currently available to, and
expectations and assumptions  deemed  reasonable by, the company.  Because these
forward-looking  statements  are  subject  to various  risks and  uncertainties,
actual results may differ  materially  from those  projected in the  statements.
These  expectations,   assumptions  and  uncertainties  include:  the  company's
expectation  of  continued  growth in the demand for  electricity;  belief  that
legislation  and  regulations  relating to the Clean Air Act and the  relatively
higher costs of competing  fuels will  increase  demand for its  compliance  and
low-sulfur  coal;  expectation of continued  improved market  conditions for the
price of coal;  expectation  that the company  will  continue  to have  adequate
liquidity from its cash flow from operations, together with available borrowings
under its credit  facilities,  to finance the company's working capital needs; a
variety of operational, geologic, permitting, labor and weather related factors;
and the other risks and  uncertainties  which are described from time to time in
the company's reports filed with the Securities and Exchange Commission.
