Non-GAAP Financial Measures

This press release and the related conference call contain non-GAAP financial measures. In evaluating the Company’s performance, management uses certain non-GAAP financial measures to supplement consolidated financial statements prepared under GAAP.

Management believes that non-GAAP net income and other non-GAAP financial measures used in this press release allow management to gain a better understanding of the Company’s comparative operating performance from period-to-period and to its competitors’ operating results. Management also believes these non-GAAP financial measures help indicate the Company’s baseline performance before gains, losses or charges that are considered by management to be outside ongoing operating results. Accordingly, management uses these non-GAAP financial measures for planning and forecasting of future periods and in making decisions regarding operations performance and the allocation of resources. Management believes these non-GAAP financial measures, when read in conjunction with the Company’s GAAP financials, provide useful information to investors by offering:

• the ability to make more meaningful period-to-period comparisons of the Company’s ongoing operating results;

• the ability to better identify trends in the Company’s underlying business and perform related trend analysis;

• a better understanding of how management plans and measures the Company’s underlying business; and

• an easier way to compare the Company’s most recent results of operations against investor and analyst financial models.

Management excludes certain gains or losses and benefits or costs in determining non-GAAP net income that are the result of infrequent events or arise outside the ordinary course of our continuing operations. Management believes that it is appropriate to evaluate the Company’s operating performance by excluding those items that are not indicative of ongoing operating results or limit comparability. Such items include: (i) legal fees associated with indemnification obligations to former directors and officers and other related costs, (ii) legal fees associated with certain pre-acquisition litigation, (iii) acquisition and integration costs (in connection with the Foundry acquisition), (iv) in-process research and development charge (in connection with the Foundry acquisition), (v) loss on sale of investments and (vi) acquisition-related financing charges (in connection with the Foundry acquisition).

Management also excludes the following non-cash charges in determining non-GAAP net income: (i) stock-based compensation expense and (ii) amortization of purchased intangible assets, (iii) goodwill and acquisition related intangible impairment. Because of varying available valuation methodologies, subjective assumptions and the variety of award types, management believes that the exclusion of stock-based compensation allows for more accurate comparisons of our operating results to our peer companies. Management believes that the expense associated with the amortization of acquisition-related intangible assets is appropriate to be excluded because a significant portion of the purchase price for acquisitions may be allocated to intangible assets that have short lives and exclusion of the amortization expense allows comparisons of operating results that are consistent over time for the Company’s newly acquired and long-held businesses.

Page 3 of 10

Finally, management believes that it is appropriate to exclude the tax effects of the items noted above in order to present a more meaningful measure of non-GAAP net income.

Limitations. These non-GAAP financial measures have limitations, however, because they do not include all items of income and expense that impact the Company. Management compensates for these limitations by also considering the Company’s GAAP results. The non-GAAP financial measures the Company uses are not prepared in accordance with, and should not be considered an alternative to, measurements required by GAAP, such as operating income, net income (loss) and net income (loss) per share, and should not be considered measures of the Company’s liquidity. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the most directly comparable GAAP measures. In addition, these non-GAAP financial measures may not be comparable to similar measures reported by other companies.
