Any statements contained in this communication that are not statements of historical fact may be deemed to be forward-looking statements. These forward- looking statements are based upon Anchiano’s and Chemomab’s current expectations. Forward-looking statements involve risks and uncertainties.Because such statements deal with future events and are based on Anchiano’s and Chemomab’s current expectations, they are subject to various risks and uncertainties and actual results, performance or achievements of Anchiano or the combined company could differ materially from those described in or implied by the statements in this presentation, including: the risk related to Anchiano’s and Chemomab’s ability to complete the merger on the proposed terms and schedule, including risks and uncertainties related to the satisfaction of the closing conditions related to the merger agreement and risks and uncertainties related to the failure to timely or at all obtain shareholder approval for the transaction; the execution of definitive agreements with certain existing Chemomab shareholders including risks and uncertainties related to the satisfaction of the closing conditions related to the financing; the uncertain and time- consuming regulatory approval process; risks related to the combined company’s ability to correctly manage its operating expenses and its expenses; risks related to the market price of Anchiano’s ADSs relative to the exchange ratio; unexpected costs, charges or expenses resulting from the transaction; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed merger transaction; combined company’s plans to develop and commercialize its product candidates, including CM-101 and RAS; the timing of initiation of combined company’s planned clinical trials; the timing of the availability of data from combined company’s clinical trials; the timing of any planned investigational new drug application or new drug application; combined company’s plans to research, develop and commercialize its current and future product candidates; the clinical utility, potential benefits and market acceptance of combined company’s product candidates; combined company’s commercialization, marketing and manufacturing capabilities and strategy; the combined company’s ability to protect its intellectual property position; and the requirement for additional capital to continue to advance these product candidates, which may not be available on favorable terms or at all.
