Forward-looking

Statements

The

Company cautions that all statements, other than statements of historical facts, contained in this Current Report on Form 8-K, or furnished

herewith, are forward-looking statements. Forward-looking statements are subject to known and unknown risks, uncertainties, and other

factors that may cause our or our industry’s actual results, levels or activity, performance or achievements to be materially different

from those anticipated by such statements. The use of words such as “may,” “might,” “will,” “should,”

“could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,”

“project,” “intend,” “future,” “potential,” or “continue,” and other similar

expressions are intended to identify forward looking statements. However, the absence of these words does not mean that statements are

not forward-looking. All forward-looking statements are based on current estimates, assumptions and expectations by our management that,

although we believe to be reasonable, are inherently uncertain. Any forward-looking statement expressing an expectation or belief as

to future events is expressed in good faith and believed to be reasonable at the time such forward-looking statement is made. However,

these statements are not guarantees of future events and are subject to risks and uncertainties and other factors beyond our control

that may cause actual results to differ materially from those expressed in any forward-looking statement, including, but not limited

to: (i) the initiation, timing, cost, progress and results of our preclinical and clinical studies and our research and development programs,

(ii) our ability to advance product candidates into, and successfully complete, clinical studies, (iii) the timing or likelihood of regulatory

filings and approvals, (iv) our ability to develop, manufacture and commercialize our product candidates and to improve the manufacturing

process, (v) the rate and degree of market acceptance of our product candidates, (vi) the size and growth potential of the markets for

our product candidates and our ability to serve those markets, and (vii) our expectations regarding our ability to obtain and maintain

intellectual property protection for our product candidates. Any forward-looking statement speaks only as of the date on which it was

made. The Company undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information,

future events or otherwise, except as required by law.
