Appendix

About Non-GAAP Financial Measures The following tables include a reconciliation of certain financial measures prepared in accordance with Generally Accepted Accounting Principles (“GAAP”) to the most directly comparable financial measures not prepared in accordance with GAAP (“non-GAAP”). Non-GAAP financial measures should not be considered in isolation or as a substitute for comparable GAAP financial measures. The non-GAAP financial measures we present in the following tables have limitations in that they do not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP, and these non-GAAP financial measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP financial measures. These non-GAAP financial measures do not represent discretionary cash available to us to invest in the growth of our business, and we may in the future incur expenses similar to the adjustments made in these non-GAAP financial measures. We believe that the non-GAAP financial measures we present in the following tables provide meaningful supplemental information regarding our operating results primarily because they exclude certain non-cash charges or items that we do not believe are reflective of our ongoing operating results when budgeting, planning and forecasting, determining compensation and when assessing the performance of our business with our individual operating segments or our senior management. We believe that these non-GAAP financial measures also facilitate the comparison by management and investors of results between periods and among our peer companies. However, those companies may calculate similar non-GAAP financial measures differently than we do, limiting their usefulness as comparative measures. Our non-GAAP financial measures reflect adjustments to the corresponding GAAP financial measure based on the items set forth below. The purpose of these adjustments is to give an indication of our performance exclusive of certain non-cash charges and other items that are considered by our senior management to be outside of our ongoing operating results.

About Non-GAAP Financial Measures Revenue adjustments related to acquisitions. We exclude from our non-GAAP revenue the impact of fair value adjustments required under GAAP relating to acquired customer support contracts which would have otherwise been recognized on a standalone basis. We exclude these adjustments from our non-GAAP financial measures because these are not reflective of our ongoing operations. Amortization of acquired intangible assets, including acquired technology. When we acquire an entity, we are required under GAAP to record the fair values of the intangible assets of the acquired entity and amortize those assets over their useful lives. We exclude the amortization of acquired intangible assets, including acquired technology, from our non-GAAP financial measures. These expenses are excluded from our non-GAAP financial measures because they are non-cash charges. In addition, these amounts are inconsistent in amount and frequency and are significantly impacted by the timing and size of acquisitions. Thus, we also exclude these amounts to provide better comparability of pre- and post-acquisition operating results. Stock-based compensation expenses. We exclude stock-based compensation expenses related to stock options, restricted stock awards and units, stock bonus plans and phantom stock from our non-GAAP financial measures. These expenses are excluded from our non-GAAP financial measures because they are primarily non-cash charges. In prior periods, we also incurred (and excluded from our non-GAAP financial measures) significant cash-settled stock compensation expense due to our previous extended filing delay and restrictions on our ability to issue new shares of common stock to our employees. M&A and other adjustments. We exclude from our non-GAAP financial measures legal, other professional fees and certain other expenses associated with acquisitions, whether or not consummated, and certain extraordinary transactions, including reorganizations, restructurings and expenses associated with our merger with CTI. Also excluded are changes in the fair value of contingent consideration liabilities associated with business combinations, and expenses related to our restatement of previously filed financial statements and our previous extended filing delay. These expenses are excluded from our non-GAAP financial measures because we believe that they are not reflective of our ongoing operations.

About Non-GAAP Financial Measures Unrealized (gains) losses on derivatives, net. We exclude from our non-GAAP financial measures unrealized gains and losses on interest rate swaps and foreign currency derivatives. These gains and losses are excluded from our non-GAAP financial measures because they are non-cash transactions which are highly variable from period to period and which we believe are not reflective of our ongoing operations. Loss on extinguishment of debt. We exclude from our non-GAAP financial measures loss on extinguishment of debt attributable to refinancing of our debt because we believe it is not reflective of our ongoing operations. Non-cash tax adjustments. We exclude from our non-GAAP financial measures non-cash tax adjustments, which represent the difference between the amount of taxes we actually paid and our GAAP tax provision on an annual basis. On a quarterly basis, this adjustment reflects our expected annual effective tax rate on a cash basis. Integration costs. We exclude from our non-GAAP financial measures expenses directly related to the integration of Witness. These expenses are excluded from our non-GAAP financial measures because they are not reflective of our ongoing operations. In-process research and development. We exclude from our non-GAAP financial measures the fair value of incomplete in-process research and development projects that had not yet reached technological feasibility and have no known alternative future use as of the date of the acquisition. These expenses are excluded from our non-GAAP financial measures because they are non-cash charges that we do not believe are reflective of our ongoing operations. Impairments of goodwill and other acquired intangible assets. Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and identifiable intangible assets acquired. We exclude from our non-GAAP financial measures charges relating to impairment of goodwill and acquired identifiable intangible assets. These expenses are excluded from our non-GAAP financial measures because they are non-cash charges.

About Non-GAAP Financial Measures Other legal expenses (recoveries). We exclude from our non-GAAP financial measures other legal fees and settlements associated with certain intellectual property litigations assumed in connection with the Witness acquisition. We excluded these items from our non-GAAP financial measures because they are not reflective of our ongoing operations. Expenses related to our previous extended filing delay. We exclude from our non-GAAP financial measures expenses related to our restatement of previously filed financial statements and our extended filing delay. These expenses included professional fees and related expenses as well as expenses associated with a special cash retention program. These expenses are excluded from our non-GAAP financial measures because they are not reflective of our ongoing operations. Restructuring costs. We exclude from our non-GAAP financial measures expense associated with the restructuring of our operations due to internal or external market factors. These expenses are excluded from our non-GAAP financial measures because we believe they are not reflective of our ongoing operations. Settlement with OCS. In the year ended January 31, 2007, we recorded a charge related to our July 31, 2006 settlement with the Office of Chief Scientist in Israel (“OCS”), pursuant to which we exited a royalty-bearing program and the OCS accepted a settlement of our royalty obligations under this program. We exclude from our non-GAAP financial measures expenses associated with exiting this program because they are not reflective of our ongoing operations. Gain on sale of land. We exclude from our non-GAAP financial measures the gain from the sale of a parcel of land. This gain is excluded from our non-GAAP financial measures because it is not reflective of our ongoing operations.
