The Trust will redeem all or any part of the Series M Preferred Shares that holders have properly tendered for redemption during the 60-day period prior to each of June 26, 2027, December 26, 2027, and June 26, 2028, at the Redemption Price per share.

(d) Mandatory Put.

The holders of the Series M Preferred Shares will be deemed to have properly tendered for purchase all Series M Preferred Shares held by such holders on December 26, 2026 (the “Mandatory Put Date”), and the Trust will purchase all of the Series M Preferred Shares tendered for purchase on the Mandatory Put Date (the “Mandatory Put”) at a price equal to the Liquidation Preference plus accumulated but unpaid dividends and distributions (whether or not earned or declared by the Trust) to, but not including, the Mandatory Put Date (the “Mandatory Put Price”). Notwithstanding the foregoing, a holder of Series M Preferred Shares may opt out of the Mandatory Put by submitting to the Trust a Mandatory Put Election Form, in the form provided to each holder of Series M Preferred Shares by the Trust, no fewer than two days prior to the applicable Mandatory Put Date.

(e) Procedures for Mandatory Put.

(i) No fewer than 14 days prior to the Mandatory Put Date, the Trust shall mail a written notice (the “Mandatory Put Notice”) by first class mail, postage prepaid, to each holder of the Series M Preferred Shares at such holder’s address as the same appears on the share register of the Trust at the close of business on such date as the Board of Trustees or its delegatee may determine, which date shall not be earlier than the second Business Day prior to the date upon which such Mandatory Put Notice is mailed to the holders of Series M Preferred Shares. Such notice shall include an election form by which holders of Series M Preferred Shares may opt out of the Mandatory Put (the “Mandatory Put Election Form”). Holders wishing to opt out of the Mandatory Put must return a properly completed and signed Mandatory Put Election Form indicating such election to the Trust in accordance with the instructions contained in the Mandatory Put Notice no fewer than two days prior to the Mandatory Put Date.

(ii) By the close of business on the Mandatory Put Date, the Trust shall (A) deposit with the Dividend-Disbursing Agent Deposit Assets that shall mature (if such assets constitute debt securities or time deposits) on or prior to the Mandatory Put Date, having an initial combined value sufficient to effect the purchase of the Series M Preferred Shares to be purchased pursuant to the Mandatory Put and (B) give the Dividend-Disbursing Agent irrevocable instructions and authority to pay the Mandatory Put Price to the holders of the Series M Preferred Shares tendered for purchase pursuant to the Mandatory Put. The Trust may direct the Dividend-Disbursing Agent with respect to the investment of any Deposit Assets so deposited provided that the proceeds of any such investment will be available at the opening of business on the Mandatory Put Date. Upon the date of such deposit (unless the Trust shall default in making payment of the Mandatory Put Price), all rights of the holders of the Series M Preferred Shares so tendered for purchase shall cease and terminate except the right of the holders thereof to receive the Mandatory Put Price thereof and such shares shall no longer be deemed Outstanding for any purpose. The Trust shall be entitled to receive, promptly, any cash in excess of the aggregate Mandatory Put Price of the Series M Preferred Shares tendered for purchase pursuant to the Mandatory Put and any remaining Deposit Assets. Any assets so deposited that are unclaimed at the end of two years from the Mandatory Put shall, to the extent permitted by law, be repaid to the Trust, after which the holders of the Series M Preferred Shares so tendered for purchase pursuant to the Mandatory Put shall look only to the Trust for payment of the Mandatory Put Price thereof. The Trust shall be entitled to receive, from time to time after Mandatory Put Date, any interest on the Deposit Assets so deposited.

(iii) On or after the Mandatory Put Date, each holder of Series M Preferred Shares that are tendered for purchase pursuant to the Mandatory Put shall surrender such shares to the Trust as instructed in the Mandatory Put Notice and shall then be entitled to receive the cash Mandatory Put Price, without interest.

THIRTEENTH: Capitalized terms used but not defined herein shall have the respective meanings given to them in the Statement of Preferences of the Series M Preferred Shares.
