The following factors, among others, could cause actual results to differ from those set forth in the forward-looking statements: the ability to obtain regulatory approvals of the transaction on the proposed terms and schedule; the failure of Citizens or Republic shareholders to approve the transaction; the risk that the businesses will not be integrated successfully; deposit attrition and disruption from the transaction making it more difficult to maintain relationships with customers, employees or suppliers; the risk that the cost savings and any other synergies from the transaction may not be fully realized or may take longer to realize than expected; competition and its effect on pricing, spending, third-party relationships and revenues; movements in market interest rates and secondary market volatility; divestitures assumed and/or required; potential conditions that may affect the tax-free status of the Republic stock exchange for Citizens' common shares; and unfavorable changes in economic and business conditions or the regulatory environment.
