(*) Use of Non-GAAP Financial Information

In addition to reporting financial results in accordance with U.S. generally accepted accounting principles, or GAAP, Attunity uses Non-GAAP measures of net income (loss), operating expenses, operating profit (loss), and diluted net income (loss) per share, which are adjusted from results based on GAAP to exclude amortization and impairment charges associated with the acquisitions, stock-based compensation expenses, non-cash financial expenses, such as the effect of a revaluation of liabilities presented at fair value and accretion of payment obligations, and tax benefits related to non-GAAP adjustments. Attunity's management believes the non-GAAP financial information provided in this release is useful to investors' understanding and assessment of Attunity's on-going core operations and prospects for the future. Management uses both GAAP and non-GAAP information in evaluating and operating its business internally and as such has determined that it is important to provide this information to investors. The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP. For further details, see the Reconciliation of Supplemental Non-GAAP Financial Information table later in this press release.

Important Note: Attunity is not responsible for the awards mentioned in this press release or the entities that award them.
