Forward-Looking Statements

Certain statements made herein are "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts are forward-looking statements. These forward-looking statements include information about our possible or assumed future results of operations or our performance. Words such as "anticipate," "contemplate," "appear," "approximate," "believe," "continue," "could," "estimate," "expect," "foresee," "intend," "may," "might," "plan," "possible," "potential," "predict," "project," "seek," "should," "will," "would" and variations of such words and similar expressions (or the negative version of such words or expressions) may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. These statements are based on current expectations on the date hereof and involve a number of risks and uncertainties that may cause actual results to differ significantly. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, including without limitation the completion of the Company's annual audit procedures and its ability to file the 2023 Form 20-F timely, many of which are outside the Company's control, that could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. The Company does not assume any obligation to update or revise any such forward-looking statements, whether as the result of new developments or otherwise.
