     Pro Forma Financial Results

     We prepare and release quarterly unaudited financial statements prepared in
accordance with generally accepted accounting principles ("GAAP"). We also
disclose and discuss certain pro forma financial information, used to evaluate
our performance, in this and other earnings releases and investor conference
calls. We believe that current shareholders and potential investors in our
company use multiples of pro-forma EPS in making investment decisions about our
company. We use pro-forma EPS to evaluate the results of our ongoing operations
and to assist in historical comparisons. This measure, and other pro-forma
information, should not be considered an alternative to measurements required by
accounting principles generally accepted in the United States of America such as
net income and net cash provided by operations and should not be considered
measures of our liquidity. In addition, our non-GAAP measures may not be
comparable to similar measures reported by other companies. Our key non-GAAP
measure is:

     Pro-forma EPS

     Pro-forma EPS is calculated by dividing pro-forma net income by the diluted
number of shares. Pro-forma Net Income excludes certain non-cash and special
charges, consisting primarily of non-cash compensation charges,
in-process-research-and-development costs, amortization of intangible assets and
transaction costs associated with acquisitions. This pro forma calculation also
substitutes current period GAAP tax provisions with a pro forma tax rate of 28%.
Historically, we have had significant deferred tax assets and have not recorded
a significant federal tax provision and so the GAAP tax provision related
primarily to state and foreign taxes and has been minimal.
     From a tax return perspective, and thus cash flow perspective, we do not
believe Concord will pay significant state or federal income taxes for at least
2 years. We will continue incurring small foreign, federal minimum and state
minimum tax payments. Due to the release of our valuation allowance in the
fourth quarter of 2003, our GAAP tax rate has increased to 38%. We will continue
providing pro forma guidance and results at a 28% tax rate to normalize our
results against historical reported results and are provided for comparative
purposes only.
