Forward Looking Statements This presentation contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act. These forward-looking statements include, among other things, statements regarding the clinical development pathway for CM-101; the proposed merger between Chemomab and Anchiano; expectations regarding ownership structure of the combined company; the future operations of the combined company and its ability to successfully initiate and complete clinical trials and achieve regulatory milestones; the nature, strategy and focus of the combined company; the development and commercial potential and potential benefits of any product candidates of the combined company; that the proposed merger will close and will enable the combined company to participate in the possible success of the combined company’s product candidates; and that the product candidates have the potential to address high unmet needs of patients with serious fibrosis-related diseases and conditions. 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. In addition, there can be no assurance that Anchiano and Chemomab will be able to complete the transactions contemplated by the merger agreement or related transactions. Additional risks and uncertainties relating to Anchiano and its business can be found under the caption “Risk Factors” and elsewhere in Anchiano’s filings and reports with the SEC, including in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 17, 2020 as updated by its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020, June 30, 2020 and September 30, 2020, filed with the SEC on May 7, 2020, August 14, 2020 and November 16, 2020, respectively, and its other subsequent filings with the SEC.
