About Non-GAAP Financial Measures

This press release and the accompanying tables include non-GAAP financial measures. For a description of these non-GAAP financial measures, including the reasons management uses each measure, and reconciliations of these non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with GAAP, please see Tables 2 and 3 as well as “Supplemental Information About Non-GAAP Financial Measures” at the end of this press release. Because we do not predict special items that might occur in the future, and our outlook is developed at a level of detail different than that used to prepare GAAP financial measures, we are not providing a reconciliation to GAAP of our forward-looking financial measures for the year ending January 31, 2013.

Supplemental Information About Non-GAAP Financial Measures

This press release contains non-GAAP financial measures. Tables 2 and 3 include a reconciliation of each non-GAAP financial measure presented in this press release to the most directly comparable GAAP financial measure. 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 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 or in addition to the adjustments made in these non-GAAP financial measures.

We believe that the non-GAAP financial measures we present 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.

Adjustments to 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.

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

10

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.
