        <footnote id="F1">Shares were issued pursuant to the director's existing election to purchase, at market value, newly issued shares of Class C Non-Voting Common Stock in lieu of receiving some or all of the director's quarterly retainer in cash. The market value is the closing price of the stock on September 30, 2022, the last business day of the quarter, as reported by the New York Stock Exchange.</footnote>
        <footnote id="F2">Includes 477 unvested restricted stock units of Farmer Mac's Class C Non-Voting Common Stock that will vest on March 31, 2023 if the Reporting Person remains a director of Farmer Mac on that date.</footnote>
        <footnote id="F3">The amount of securities beneficially owned following the reported transaction reported in Column 5 of Table I reflects the addition of 45 shares of Class C Non-Voting Common Stock compared to the amounts previously reported in the Form 3 filed by the Reporting Person on May 24, 2022 and in the Form 4s filed by the Reporting Person on May 25, 2022 and July 5, 2022. This corrects an error originally made in the referenced Form 3, which inadvertently transposed the number of securities owned in Column 2 of Table I and incorrectly reported ownership of 2,449 shares of Class C Non-Voting Stock rather than the correct holdings as of May 24, 2022, of 2,494 shares.</footnote>
