Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to EPR Properties, a Maryland real estate investment trust (the “Company”), and, at the request of the Company, have examined the registration statement on Form S-3 (the “Registration Statement”) to be filed by the Company on or about the date hereof with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), and regulations promulgated thereunder. Capitalized terms not otherwise defined herein have the meanings ascribed to them in the Registration Statement.

The Registration Statement relates to, among other things, the registration under the Securities Act of an indeterminate number or amount of (i) debt securities of the Company (the “Debt Securities”), (ii) common shares of beneficial interest, $0.01 par value per share, of the Company (the “Common Shares”), (iii) preferred shares of beneficial interest, $0.01 par value per share, of the Company (the “Preferred Shares”), (iv) depositary shares representing Preferred Shares (“Depositary Shares”) evidenced by depositary receipts therefor (“Depositary Receipts”), (v) warrants to purchase one or more classes of securities registered under the Registration Statement (the “Warrants”), and (vi) units comprised of one or more classes of securities registered under the Registration Statement (the “Units” and, together with the Debt Securities, the Common Shares, the Preferred Shares, the Depositary Shares and the Warrants, the “Registered Securities”), in each case, which may be offered from time to time, as set forth in the prospectus forming a part of the Registration Statement (the “Prospectus”), and as may be set forth in one or more final supplements to the Prospectus (each, a “Prospectus Supplement”).

As described in the Prospectus, (i) the Debt Securities are to be issued in one or more series pursuant to one or more indentures (each, an “Indenture”) to be entered into between the Company and one or more trustees party thereto (each, a “Trustee”), substantially in the form of Exhibit 4.14, Exhibit 4.15 or Exhibit 4.16 to the Registration Statement and, in the case of the Debt Securities, are to be evidenced by the Company’s notes (collectively, the “Notes”) substantially in the form of Exhibit A to the applicable form of Indenture, (ii) the Depositary Shares are to be issued in one or more series pursuant to one or more depositary agreements (each, a “Depositary Agreement”) to be entered into between the Company and the depositary party thereto (each, a “Depositary”), (iii) the Warrants are to be issued in one or more series pursuant to one or more warrant agreements (each, a “Warrant Agreement”) to be entered into between the Company and the warrant agent party thereto (each, a “Warrant Agent”), and (iv) the Units are to be issued in one or more series pursuant to one or more unit agreements (each, a “Unit Agreement”) to be entered into between the Company and the unit agent party thereto (each, a “Unit Agent”), as applicable. Each Indenture, Note, Depositary Agreement, Warrant Agreement and Unit Agreement, and each underwriting agreement and other agreement or instrument, if any, that are hereafter required to be filed as an exhibit to the Registration Statement by an amendment thereto or by the filing of a Form 8-K by the Company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and incorporated by reference in the Registration Statement, in connection with an offering of Registered Securities are referred to herein as “Related Documents”.

As the basis for the opinions expressed herein, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration Statement, including the Prospectus, (ii) the Amended and Restated Declaration of Trust of the Company, as amended to date (the “Charter”), (iii) the Amended and Restated Bylaws of the Company, as amended to date (the “Bylaws”), (iv) resolutions and the record of actions taken by the Company’s board of trustees and committees thereof and by the Company’s shareholders, in each case, with respect to, among other things, the authorization and approval of the applicable Registered Securities and the preparation and filing with the Commission of the Registration Statement, and (v) such other instruments, documents and corporate records as
