Cautionary Note Regarding Forward-Looking Statements

Some of the statements contained or incorporated by reference in this Current Report on Form 8-K are forward-looking statements.  Such forward-looking statements are subject to risks and uncertainties, including, in particular, statements about our plans, strategies and prospects. Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions.  Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict.  Our actual results may differ materially from those contemplated by the forward-looking statements.  They are neither statements of historical fact nor guarantees or assurances of future performance.  The matters referred to in the forward-looking statements contained in this Current Report on Form 8-K may not in fact occur.  We caution you therefore against relying on any of these forward-looking statements.  Important factors that could cause actual results to differ materially from those in the forward-looking statements include regional, national or global political, economic, business, competitive, market and regulatory conditions and other factors that are discussed in other documents we file with the Securities and Exchange Commission, such as those set forth in our Annual Report on Form 10-K for the year ended December 31, 2012 and any subsequent Quarterly Reports on Form 10-Q.

Any forward-looking statement made by us in this Current Report on Form 8-K speaks only as of the date on which it is made.  Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them.  We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.
