Forward-Looking Statements

This press release contains forward-looking statements. Forward-looking statements involve known and unknown risks and uncertainties, which may cause Catalyst's actual results in future periods to differ materially from forecasted results. A number of factors, including the anticipated timing of the receipt of top-line results from the double-blind, placebo-controlled portion of the Phase 3 trial of Firdapse ™ , whether historic metrics of patients enrolled in the trial who complete the run-in phase of the trial and are randomized into the double-blind, placebo-controlled portion of the trial will continue to apply, such that at least 36 patients will be randomized into the double-blind, placebo-controlled portion of the trial from the patients already enrolled in the trial, whether the Phase 3 trial will be successful, whether the receipt of breakthrough therapy designation for Firdapse ™ will expedite the development and review of Firdapse ™ by the FDA or the likelihood that the product will be found to be safe and effective, whether an NDA for Firdapse ™ will ever be accepted for filing by the FDA, the timing of any such NDA filing or acceptance, whether Catalyst will be the first company to receive an approval for 3,4-DAP, giving it 7-year marketing exclusivity for its product, whether any of Catalyst's product candidates will ever be approved for commercialization or successfully commercialized, and those other factors described in Catalyst's Annual Report on Form 10-K for the fiscal year 2013 and its other filings with the U.S. Securities and Exchange Commission (SEC), could adversely affect Catalyst.
