1 Forward-looking Statements Important note regarding forward-looking statements: Statements made in this presentation which are not purely historical are forward-looking statements, as defined in the Private Securities Litigation Reform Act of 1995. This includes any statements regarding management’s plans, objectives, or goals for future operations, products or services, and forecasts of its revenues, earnings, or other measures of performance. Such forward-looking statements may be identified by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “estimate,” “should,” “will,” “intend,” "target," “outlook” or similar expressions. Forward-looking statements are based on current management expectations and, by their nature, are subject to risks and uncertainties. Actual results may differ materially from those contained in the forward-looking statements. These forward-looking statements include: management plans relating to the pending sale of Whitnell & Co. and formation of a strategic partnership with Rockefeller (the “transaction”); the expected timing of the completion of the transaction; the ability to complete the transaction; the ability to obtain any required regulatory approvals; any statements of the plans and objectives of management for future operations, products or services; any statements of expectation or belief; projections related to certain financial results or other benefits of the transaction; and any statements of assumptions underlying any of the foregoing. Factors which may cause actual results to differ materially from those contained in such forward-looking statements include those identified in the Company’s most recent Form 10-K and subsequent Form 10-Qs and other SEC filings, and such factors are incorporated herein by reference. Additional factors which may cause actual results of the transaction to differ materially from those contained in forward-looking statements are the possibility that expected benefits of the transaction may not materialize in the timeframe expected or at all, or may be more costly to achieve; the transaction may not be timely completed, if at all; that required regulatory approvals are not obtained or other customary closing conditions are not satisfied in a timely manner or at all; reputational risks and the reaction of shareholders, customers, employees or other constituents to the transaction; and diversion of management time on acquisition-related matters.

Presentation: Within the charts and tables presented, certain segments, columns and rows may not sum to totals shown due to rounding. Non-GAAP Measures: This presentation includes certain non-GAAP financial measures. These non-GAAP measures are provided in addition to, and not as substitutes for, measures of our financial performance determined in accordance with GAAP. Our calculation of these non-GAAP measures may not be comparable to similarly titled measures of other companies due to potential differences between companies in the method of calculation. As a result, the use of these non-GAAP measures has limitations and should not be considered superior to, in isolation from, or as a substitute for, related GAAP measures. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures can be found at the end of this presentation.

The fully tax-equivalent efficiency ratio is noninterest expense (which includes the provision for unfunded commitments), excluding other intangible amortization, divided by the sum of fully tax-equivalent net interest income plus noninterest income, excluding investment securities gains / losses, net. The adjusted efficiency ratio is noninterest expense, which excludes the provision for unfunded commitments, other intangible amortization, acquisition related costs, and 3Q20 initiatives, divided by the sum of fully tax-equivalent net interest income plus noninterest income, excluding investment securities gains (losses), net, acquisition related costs, asset gains (losses), net and gain on sale of branches. Management believes the adjusted efficiency ratio is a meaningful measure as it enhances the comparability of net interest income arising from taxable and tax-exempt sources and provides a better measure as to how the Corporation is managing its expenses by adjusting for acquisition related costs, provision for unfunded commitments, asset gains (losses), net, branch sales, and 3Q 2020 initiatives.
