• Forward-Looking Statements - Any forward-looking statements contained in this presentation are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and speak only as of the date of this presentation. You can identify these forward-looking statements by the fact that they use words such as "should," "anticipate," "estimate," "approximate," "expect," "target," "may," "will," "project," "intend," "plan," "believe" and other words of similar meaning and expression in connection with any discussion of future operating or financial performance. Forward-looking statements are inherently subject to a variety of risks and uncertainties that could cause actual results to differ materially from those projected. Risk factors are included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2009 and our other filings with the Securities and Exchange Commission (the “SEC”). We can give no assurance that any goal, plan or target set forth in forward-looking statements can be achieved and readers are cautioned not to place undue reliance on such statements, which speak only as of the date made. We undertake no obligation to release publicly any revisions to forward-looking statements as a result of future events or developments.

• GAAP Reconciliation -This presentation also includes, as a supplement to United States Generally Accepted Accounting Principles (“GAAP”), certain non-GAAP financial measures. These non-GAAP financial measures exclude the impact of certain items and, therefore, have not been calculated in accordance with GAAP. Pursuant to the requirements of the SEC’s Regulation G, we provide in our SEC filings additional information regarding these non-GAAP financial measures, including a reconciliation of them to their most comparable GAAP financial measures, management’s explanations regarding the use and usefulness of non-GAAP financial measures and the limitations associated with the use of non-GAAP financial measures. The Company's non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measurements, and should be read only in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP.
