All statements other than present and historical facts and conditions contained in this Form 10-Q, including statements regarding our future results of operations and financial position, business strategy, plans and objectives for future operations, are forward-looking statements and involve risks and uncertainties that could cause actual results to differ materially. When used in this Form 10-Q, the words “anticipate,” “believe,” “can,” “could,” “estimate,” “expect,” “intend,” “is designed to,” “may,” “might,” "objective," “plan,” “potential,” “predict,” "project," "seek," “should,” "will," "would," or the negative of these and similar expressions identify forward-looking statements.

You should refer to Item 1A “Risk Factors” of this quarterly report, for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-looking statements in this Form 10-Q will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time frame or at all.
