Changes in, or interpretations of, tax rules and regulations may adversely affect our effective tax rates.

We are subject to income taxes in both the U.S. and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We are subject to audit by various tax authorities. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different than that which is reflected in historical income tax provisions and accruals. Should additional taxes be assessed as a result of an audit or litigation, an adverse effect on our income tax provision and net income in the period or periods for which that determination is made could result.

On February 8, 2007, a holder of an outstanding warrant exercised its right to purchase 39,328 shares of our common stock at $14.16 per share on a cashless exercise basis.
