Cautionary Note Regarding Forward-Looking Statements

This Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements contained in this Form 8-K other than statements of historical fact should be considered forward-looking statements, including, without limitation, statements regarding the terms and conditions of, and completion of, the Exchanges. The Company cannot assure that the exchanges will be consummated, nor can it guarantee the size or terms of the exchanges. Forward-looking statements generally can be identified by words such as “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” “should,” “may,” “will,” “will continue,” “can,” “could,” or the negative of these words, variations of these words and comparable terminology, in each case, intended to refer to future events or circumstances. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. Forward-looking statements are based on information available to the Company as of the date of this Form 8-K and are subject to known and unknown risks and uncertainties that could cause the Company’s actual results, performance or events to differ materially from historical experience and the Company’s present expectations or projections. These risks and uncertainties include, but are not limited to, those described under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s latest periodic report on Form 10-Q or Form 10-K filed with the U.S. Securities and

Exchange Commission. Undue reliance should not be placed on the forward-looking statements in this Form 8-K, which are based on information available to us on, and which speak only as of, the date hereof. The Company undertakes no obligation to update forward-looking statements to reflect events or circumstances after the date they were made, unless required by applicable law.
