Income Tax Expense

Income tax expense was $1.17 million in 1Q10, up from $0.59 million for the same period in 2009. The increase was mainly due to the combined effects from an increase in assessable profits during the current period and the increase in tax rate as a result of China's tax rate unification program.

Net Income Attributable to the Company

As a result of the foregoing factors, net income contributable to the Company was $6.3 million in 1Q10, an increase of 67.2%, or $2.5 million in 1Q09.

Cash and Cash Equivalents

As of March 31, 2010, the Company had $17.3 million in cash and cash equivalents, restricted cash and short-term investments as compared to $19.3 million in the same period one year ago.

About Non-GAAP Financial Measures

This press release contains non-GAAP financial measures for earnings that exclude non-cash charges. China Information Security believes that these non- GAAP financial measures are useful to investors because they exclude non-cash charges that China Information Security's management excludes when it internally evaluates the performance of the Company's business and makes operating decisions, including internal budgeting, and performance measurement, because these measures provide a consistent method of comparison to historical periods. Moreover, management believes these non-GAAP measures reflect the essential operating activities of China Information Security. Accordingly, management excludes the expense arising from certain non-cash charges when making operational decisions. China Information Security believes that providing the non-GAAP measures that management uses to its investors is useful to investors for a number of reasons. The non-GAAP measures provide a consistent basis for investors to understand China Information Security's financial performance in comparison to historical periods. In addition, it allows investors to evaluate China Information Security's performance using the same methodology and information as that used by China Security's management. Non-GAAP measures are subject to inherent limitations because they do not include all of the expenses included under GAAP and because they involve the exercise of judgment of which charges are excluded from the non-GAAP financial measure. However, China Information Security's management compensates for these limitations by providing the relevant disclosure of the items excluded.

The following table provides the non-GAAP financial measure and the related GAAP measure and provides a reconciliation of the non-GAAP measure to the equivalent GAAP measure.
