        <footnote id="F1">The original Form 4, filed on June 22, 2022, is being amended by this Form 4 amendment solely to correct an administrative error, which erroneously reported the transaction code as &quot;P&quot;. The shares were acquired under Camden National Corporation's 2022 Equity and Incentive Plan and the acquisition was exempt from Section 16(b) of the Securities Exchange Act of 1934 pursuant to Rule 16b-3(d). Accordingly, this Form 4 amendment has been filed to amend the transaction code from &quot;P&quot; to &quot;A&quot;. No other amendments have been made.</footnote>
        <footnote id="F2">Shares acquired under Camden National Corporation's 2022 Equity and Incentive Plan in lieu of director fees.</footnote>
        <footnote id="F3">Consists of 2.00 shares acquired since last filing as a result of participation in the Company's dividend reinvestment program.</footnote>
