Reform Act of 1995. We intend such forward-looking statements to be covered under by the safe harbor provisions for forward- looking stateme nts contained in Secti on 27A of the Securiti es Act of 1933, as amended, and Section 21 E of the
Securiti es Exchange Act of 1934, as amended.” All statements other than statements of historical facts contained in this prese ntation, including statem ents r egarding our future results of operations and financial position, industry
dynamics, business strategy and plans, anticipated milestones and timelines for our non-clinical, pre-clinical studies and clinical trials and our objectives for future operations, are forward-looking statements. The se statem ents r epre
sent our opinions, expectations, beliefs, intentions, esti mates or strategies regardi ng the future, which may not be reali zed. In some cases, you can identify forward-looking stateme nts by terms such as “may,” “will,” “should,”
“expects,” “plans,” “anticipates,” “could,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these term s or other similar expr essions that are intended to
identify forward-looking stateme nts. Forward-looking stateme nts are based largely on our current expe ctations and projections about future events and financial trend s that we believe may affect our financial condition, results of
operations, business strategy, short term and long-term business operations and objectives and financial needs. These forward-looking stateme nts are subject to a number of risks, uncertainties and assumptions, including
without limitation the important factors described in the section titled “Risk Factors” in our most recent Annual Report on Form 10 -K filed with the Securities and Exchange Commission (“SEC”), as updated by our subseque nt filings with
the SEC, that may cause our actual results, perfor mance or achieve ments to differ materially and adversely from those expressed or implied by the forward-looking stateme nts. Moreover, we operate in a very competitive and rapidly
changing environm ent. N ew risks emer ge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of
factors, may cause actual results to differ materially from tho se contained in any forward-looking stateme nts we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in
this presentation may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking stateme nts. We caution you therefor e against relying on these forward-looking stateme nts,
and we qualify all of our forward-looking stateme nts by these cautionary statements. The forward-looking statements included in this presentation are made only as of the date hereof. Although we believe that the expectations reflected in
the forward-looking stateme nts are r easonable, we cannot guarantee that the future r esults, levels of activity, performance or events and circumstances reflecte d in the forward-looking statements will be achieved or occur. Moreover,
neither we nor our advisors nor any other person assum es responsibili ty for the accuracy and completeness of the forward-looking statements. Neither we nor our advisors undertake any obligation to update any forward-looking stateme nts
for any reason after the date of this presentation to conform these statements to actual results or to changes in our expe ctations, except as may be requi red by law. You should read this presentation with the understanding that our
actual future results, levels of activity, performance and events and circumstances may be mater ially differe nt from what we expect. Unless otherwise indicated, information contained in this presentation concerning our industry,
competitive position and the markets in which we operate is based on information from independent industry and rese arch organizations, other third-party sources and management esti mates. Manageme nt estimates are der ived from publicly
available information released by indepe ndent industry analysts and other third- party sources, as well as data from our internal research, and are based on assumptions made by us upon r evie wing such data, and our exper ience in, and
knowledge of, such industry and markets, which we beli eve to be reasonable. In addition, projections, assumptions and estimates of the future perfor mance of the industry in which we operate or of any individual competi tor and our future
performance are necessarily subject to uncertainty and risk due to a variety of factors, including those described above. These and other factors could c ause results to differ materially from those expresse d in the estim ates made
by independent parties and by us. Industry publications, research, surveys and studies generally state that the information they contain has been obtained from sources believed to be reliable , but that the accuracy and complete ness of
such information is not guaranteed. Forecasts and other forward-looking information obtained from these sources are subj ect to the same qualifications and uncertainties as the other forward-looking stateme nts in this presentation. This
