Safe Harbor Statement

Discussions in this release that are not statements of historical fact (including statements that include terms such as “will,” “may,” “should,” “believe,”
“expect,” “anticipate,” “estimate,” “intend,” and “plan”) are forward-looking statements that involve risks and uncertainties. Any forward-looking
statement is not a guarantee of future performance and actual results could differ materially from those contained in the forward-looking information.
Such forward-looking statements include, but are not limited to, statements about the benefits of the business combination transaction involving Citizens
and Republic, including future financial and operating results, the new company’s plans, objectives, expectations and intentions and other statements that
are not historical facts.

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.
Additional factors that may affect future results are contained in Citizens’ and Republic’s filings with the SEC, which are available at the SEC's web site
http://www.sec.gov. Citizens and Republic disclaim any obligation to update and revise statements contained in these materials based on new information
or otherwise.
