Forward Looking Statements
This presentation includes statements that are, or may be deemed, ‘‘forward-looking statements.’’ In some cases, these forward-looking
statements can be identified by the use of forward-looking terminology, including the terms “believes,” “estimates,” “anticipates,” “expects,”
“plans,” “intends,” “may,” “could,” “might,” “will,” “should,” “approximately” or, in each case, their negative or other variations thereon or
comparable terminology, although not all forward-looking statements contain these words. They appear in a number of places throughout this
presentation and include statements regarding our intentions, beliefs, projections, outlook, analyses or current expectations concerning, among
other things, our ongoing and planned discovery and development of drugs targeting cancer stem cells, the strength and breadth of our intellectual
property, our ongoing and planned preclinical studies and clinical trials, the timing of and our ability to make regulatory filings and obtain and
maintain regulatory approvals for our product candidates, the degree of clinical utility of our products, particularly in specific patient populations,
expectations regarding clinical trial data, our results of operations, financial condition, liquidity, prospects, growth and strategies, the length of
time that we will be able to continue to fund our operating expenses and capital expenditures, our expected financing needs and sources of
financing, the industry in which we operate and the trends that may affect the industry or us.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics, and healthcare,
regulatory and scientific developments and depend on the economic circumstances that may or may not occur in the future or may occur on longer
or shorter timelines than anticipated. Although we believe that we have a reasonable basis for each forward-looking statement contained in this
presentation, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations,
financial condition and liquidity, and the development of the industry in which we operate may differ materially from the forward-looking
