TABLE OF CONTENTS

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements, other than purely historical information, including estimates, projections, statements relating to our business plans, objectives, and expected operating results, and the assumptions upon which those statements are based, are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements generally are identified by the words “believes,” “project,” “expects,” “anticipates,” “estimates,” “intends,” “strategy,” “plan,” “may,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions. We intend such forward-looking statements to be covered by the safe-harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and are including this statement for purposes of complying with those safe-harbor provisions. Forward-looking statements are based on current expectations and assumptions that are subject to risks and uncertainties which may cause actual results to differ materially from the forward-looking statements. Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors which could have a material adverse effect on our operations and future prospects on a consolidated basis include, but are not limited to, changes in economic conditions, legislative or regulatory changes, availability of capital, interest rates, competition, and unforeseen events that may impair our ability to advance our clinical programs and raise additional financing. These risks and uncertainties should also be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. We undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Further information concerning our business, including additional factors that could materially affect our financial results, is included herein and in our other filings with the Securities and Exchange Commission (“SEC”).
