* Adjusted EBITDA: We believe Adjusted EBITDA may be useful to investors as a
performance measure and may help them understand our cash resources and
requirements.  In addition, we use Adjusted EBITDA in our internal business planning
process, in setting company performance goals and for incentive compensation
purposes.  Adjusted EBITDA does not represent cash flow from operations, as defined
under U.S. generally accepted accounting principles, and is not a measure of
operating profitability or net income.  Our computation of Adjusted EBITDA may differ
from those used by other companies should not be considered comparable.
