On December 20, 2017, Agree Realty Corporation (the “Company”) entered into the Third Amendment (the “Amendment”) to the Company’s Rights Agreement, dated as of December 7, 1998, as amended by the Amendment to Rights Agreement dated as of October 18, 2001, and by the Second Amendment to Rights Agreement dated as of December 8, 2008 (the “Agreement”), by and between the Company and Computershare Trust Company, N.A., f/k/a EquiServe Trust Company, N.A., a national banking association, as successor rights agent to BankBoston, N.A., a national banking association (the “Rights Agent”). Capitalized terms used herein but not defined shall have the meanings assigned to them in the Agreement. Pursuant to Section 27 of the Agreement, the Company amended the Agreement to add the defined term “Designated Holder” for the purpose of providing a limited exemption to a specified institutional investor and its subsidiaries and affiliates (collectively, the “Investor”) from the definition of “Acquiring Person” under the Agreement.

This limited exemption permits the Investor to become the Beneficial Owner of less than 20% of the Common Shares of the Company then outstanding without becoming an Acquiring Person rather than the 15% threshold otherwise applicable. The Investor will be deemed a Designated Holder until the earliest of (i) such time as the Investor ceases to beneficially own 10% or more of the Common Shares of the Company, (ii) the Investor or any parent entity is subject to a change of control or (iii) the Investor reports or is required to report on Schedule 13D (or any successor or comparable report) its beneficial ownership of Common Shares of the Company. The foregoing description of the Amendment is qualified in its entirety by reference to the applicable provisions of the Amendment, which is filed as Exhibit 4.1 hereto and incorporated herein by reference.

The description of the Amendment to the Agreement set forth above under Item 1.01 “Entry Into a Material Definitive Agreement” is incorporated into this Item 3.03 by reference.
