  to, statements concerning our stock repurchase program.  These statements
  are only predictions based on current information and expectations and involve
  a number of risks and uncertainties.  Actual events or results may differ
  materially from those projected in any of such statements due to various

  the price of our common stock; the performance and conditions in the United
  States and world financial markets; the policies and actions of the United
  States and other governments; and the general political, economic and business
  conditions in the United States and elsewhere.  For a discussion of these
  and other factors which may cause our actual events or results to differ from
  those projected, please refer to the company's most recent annual report on Form 10-K
