EXECUTION VERSION
 
AMENDMENT
TO
AGREEMENT AND PLAN OF MERGER
 
This AMENDMENT TO AGREEMENT AND PLAN OF MERGER (this “Amendment”),  dated as of September 22, 2026 (the “Effective Date”), is made by and among Independence Realty Trust, Inc., a Maryland corporation (“Parent”), Independence Realty Operating Partnership, LP, a Delaware limited partnership (“Parent OP”), Islanders OP Sub, LLC, a Delaware limited liability company and direct wholly owned Subsidiary of Parent OP (“OP Merger Sub”), Centerspace, a North Dakota real estate investment trust (the “Company”), Centerspace, LP, a North Dakota limited partnership (the “Company OP”), and Islanders Sub, LLC, a Delaware limited liability company (“Parent Merger Sub”).  Capitalized terms used but not otherwise defined herein shall have the meanings set forth in the Agreement (as defined below).
 
WHEREAS, the parties have previously entered into that certain Agreement and Plan of Merger (the “Agreement”), dated as of September 8, 2026, by and among Parent, Parent OP, OP Merger Sub, the Company, the Company OP and, pursuant to that Agreement and Plan of Merger Joinder, dated as of September 22, 2026, Parent Merger Sub;
 
WHEREAS, Section 8.04 of the Agreement provides that the parties may amend the Agreement by an instrument in writing signed on behalf of each of the parties thereto at any time before receipt of the Company Shareholder Approval and Parent Stockholder Approval;
 
WHEREAS, Section 1.08 of the Agreement provides that at any time prior to the date the definitive Joint Proxy Statement is filed with the SEC, Parent, in its sole discretion, may elect by written notice to the Company to modify (a) the structure of the Company Merger so that the Company merges with and into Parent Merger Sub, with Parent Merger Sub surviving, and/or (b) the structure of the Partnership Merger so as to provide that the Company OP shall merge with and into Parent OP (rather than OP Merger Sub merging with and into the Company OP), in which case (i) Parent OP shall continue as the surviving limited partnership of the Partnership Merger, and (ii) the Company GP Interest issued and outstanding immediately prior to the Partnership Merger Effective Time shall be cancelled without any consideration (the “Alternative Structure”);
 
WHEREAS, Parent has elected to modify the structure of the Company Merger (but, for the avoidance of doubt, not the structure of the Partnership Merger) in accordance with such provisions of Section 1.08 of the Agreement;
 
WHEREAS, Section 1.08 of the Agreement provides that in the event that Parent elects to implement the Alternative Structure, the parties agree, in good faith, to prepare and execute an amendment to the Agreement reasonably acceptable to the parties to reflect the Alternative Structure and any necessary modifications to the terms of the Agreement to give effect to the Alternative Structure; and
 
WHEREAS, the parties hereto wish to amend the Agreement to reflect Parent’s election of the Alternative Structure with respect to the Company Merger.
 
NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:
