In preparing such forward-looking statements, the Company has in particular assumed an average U.S. dollar to euro exchange rate of US$1.30 per €1.00 and an average Japanese yen to euro exchange rate of JPY110 to €1.00 for the 2012 third quarter; for 2012, the Company has assumed an average U.S. dollar to euro exchange rate of US$1.30 per €1.00 and an average Japanese yen to euro exchange rate of JPY107 to €1.00; however, currency values fluctuate, and the Company’s results of operations may be significantly affected by changes in exchange rates. The Company’s actual results or performance may also be materially negatively affected by changes in the current global economic context, difficulties or adverse changes affecting its partners or its relationships with its partners, changes in exchange rates, new product developments, and technological changes; errors or defects in its products; growth in market share by its competitors; and the realization of any risks related to the integration of any newly acquired company, in particular related to the integration of Gemcom software International and internal reorganizations. Unfavorable changes in any of the above or other factors described in the Company’s regulatory reports, including the 2011 Document de référence, which was filed with the French Autorité des marchés financiers (AMF) on March 29, 2012, could materially affect the Company’s financial position or results of operations.

Non-IFRS Financial Information

Readers are cautioned that the supplemental non-IFRS information presented in this press release is subject to inherent limitations. It is not based on any comprehensive set of accounting rules or principles and should not be considered as a substitute for IFRS measurements. Also, the Company’s supplemental non-IFRS financial information may not be comparable to similarly titled non-IFRS measures used by other companies. Further specific limitations for individual non-IFRS measures, and the reasons for presenting non-IFRS financial information, are set forth in the Company’s annual report for the year ended December 31, 2011 included in the Company’s 2011 Document de référence filed with the AMF on March 29, 2012.

In the tables accompanying this press release the Company sets forth its supplemental non-IFRS figures for revenue, operating income, operating margin, net income and diluted earnings per share, which exclude the effect of adjusting the carrying value of acquired companies’ deferred revenue, stock-based compensation expense, the expenses for the amortization of acquired intangible assets, other income and expense, net, certain one-time items included in financial revenue and other, net, and the income tax effect of the non-IFRS adjustments. The tables also set forth the most comparable IFRS financial measure and reconciliations of this information with non-IFRS information.

Information in Constant Currencies

When the Company believes it would be helpful for understanding trends in its business, the Company provides percentage increases or decreases in its revenue (in both IFRS as well as non-IFRS) to eliminate the effect of changes in currency values, particularly the U.S. dollar and the Japanese yen, relative to the euro. When trend information is expressed herein "in constant currencies", the results of the "prior" period have first been recalculated using the average exchange rates of the comparable period in the current year, and then compared with the results of the comparable period in the current year.
