The Balance Sheet Naturally Reprices Higher Over Time 16 Interest Rate Risk Profile Static Balance Sheet For Base Case Net Interest Income Projections  Using a static balance sheet and the year end 2021 yield curve, net interest income should expand 1 – Benefits of swap repricing • Repricing of $592MM of effective swaps at 1.95% with $405 million of forward starting swaps at 0.77% largely through the end of 2023 • Swaps lock in funding costs in a rising rate environment – Repricing of funding costs – Higher rates on loan originations  Floating - rate Initiatives help drive Net Interest Income expansion – Immediately adding more floating - rate assets • Improves rate sensitivity by ~$3 - 12MM annually – Helps mitigate the negative impact of rising short term rates With No Change in Interest Rates, Net Interest Income Should Expand with a Static Balance Sheet In The Early Years Year 1 Year 2 Year 3 Year 4 Year 5 Base Case- Net Interest Income With Floating-rate Initiatives 1 Analysis does not include benefits of net prepayment penalty income, fair values adjustments on hedges, or purchase accountin g accretion

Preparing for a Rising Rate Environment 17 Interest Rate Risk Profile Static Balance Sheet For Base Case Net Interest Income Projections Rates Up 200 bps over 24 Months  Net Interest Income declines in a rising rate environment – The duration of our assets is greater than liabilities – Approximately 25% 1 of the loan portfolio matures or reprices within one year – A steeper yield curve is favorable – The timing and the pace of interest rate increases matters – slower rate increases over longer periods of time are more favorable than an immediate shock of 100+ bps  Accelerating strategies to positively impact Net Interest Income from rising rates: – Immediately adding more floating - rate assets – Greater emphasis on growing floating - rate loans including C&I and Construction – Utilize the back - to - back loan swap program to add shorter duration loans – Grow noninterest and core deposits while lagging deposit repricing Balance Sheet Growth Expected to Outweigh Potential NIM Compression In 2022 Year 1 Year 2 Year 3 Year 4 Year 5 Rates Up 200 bps over 24 Months - Base Case Rates Up 200 bps over 24 Months - With Floating-rate Initiative 1 Does not include approximately $400MM of floating rate swaps on fixed rate loans; if the swaps are included, the percentage o f loans that mature or reprice in one year totals 31%

Non - cash Fair Value Adjustments to GAAP Earnings The variance in GAAP and core earnings is partly driven by the impact of non - cash net gains and losses from fair value adjustments . These fair value adjustments relate primarily to swaps designated to protect against rising rates and borrowing carried at fair value under the fair value option . As the swaps get closer to maturity, the volatility in fair value adjustments will dissipate . In a declining interest rate environment, the movement in the curve exaggerates our mark - to - market loss position . In a rising interest rate environment or a steepening of the yield curve, the loss position would experience an improvement . Core Net Income, Core Diluted EPS, Core ROAE, Core ROAA, Core Net Interest Income FTE, Core Net Interest Margin FTE, Base Net Interest Income FTE, Base Net Interest Margin FTE, Core Interest Income and Yield on Total Loans, Base Interest Income and Yield on Total Loans, Core Noninterest Income, Core Noninterest Expense and Tangible Book Value per common share are each non - GAAP measures used in this presentation . A reconciliation to the most directly comparable GAAP financial measures appears below in tabular form . The Company believes that these measures are useful for both investors and management to understand the effects of certain interest and noninterest items and provide an alternative view of the Company's performance over time and in comparison to the Company's competitors . These measures should not be viewed as a substitute for net income . The Company believes that tangible book value per common share is useful for both investors and management as these are measures commonly used by financial institutions, regulators and investors to measure the capital adequacy of financial institutions . The Company believes these measures facilitate comparison of the quality and composition of the Company's capital over time and in comparison to its competitors . These measures should not be viewed as a substitute for total shareholders' equity . These non - GAAP measures have inherent limitations, are not required to be uniformly applied and are not audited . They should not be considered in isolation or as a substitute for analysis of results reported under GAAP . These non - GAAP measures may not be comparable to similarly titled measures reported by other companies . 31 Reconciliation of GAAP Earnings and Core Earnings
