Explanation of Responses:

( 1 )In connection with the net share settlement of the exercise of 19,509 vested stock appreciation rights ("SARs") granted in June 2008 with a grant price of $28.94 per share, Mr. Buzby was entitled to receive 11,958 shares of the Federal Agricultural Mortgage Corporation's ("Farmer Mac") Class C Non-Voting Common Stock. Farmer Mac retained 5,704 shares to satisfy tax withholding requirements arising from the exercise, and 3,930 shares of the 6,254 shares retained by Mr. Buzby were sold on September 29, 2017. The 7,551 shares reported as a disposition to the issuer of issuer equity securities represents the difference between the number of SARs exercised and the number of shares issuable as a result of the exercise. Each SAR represents the right to receive, upon exercise, the number of shares of Farmer Mac's Class C Non-Voting Common Stock equal to the excess of the fair market value of shares on the exercise date over the grant price.
