(the “Company” or “Sorrento”) and of any of its affiliates, along with certain statements that may be made by management of the Company orally in presenting this material, may contain “forward - looking statements” as defined in the Private Securities Litigation Reform Act of 1995 . These statements can be identified by the fact that they do not relate strictly to historic or current facts . They use words such as "estimate," "expect," "intend," "believe," "plan," "anticipate," “projected” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance or condition . These statements are based upon the current beliefs and expectations of the Company's management and are subject to significant risks and uncertainties . Statements regarding future action, future performance and/or future results including, without limitation, those relating to the timing for completion, and results of, scheduled or additional clinical trials and the FDA’s or other regulatory review and/or approval and commercial launch and sales results (if any) of the Company’s formulations and products and regulatory filings related to the same, and receipt by the Company of milestone and royalty payments may differ from those set forth in the forward - looking statements . Peak sales and market size estimates have been determined on the basis of market research and comparable product analysis, but no assurances can be given that such sales levels will be achieved, if at all, or that such market size estimates will prove accurate . The Company assumes no obligation to update forward - looking statements as circumstances change .

Because actual results are affected by these and other potential risks, contingencies and uncertainties, the Company cautions investors that actual results may differ materially from those expressed or implied in any forward - looking statement . It is not possible to predict or identify all such risks, contingencies and uncertainties .
