Filing notes and footnotes

Explanation of responses 4 footnotes

Footnote F1

This amendment is being filed to correct the number of Vivmark Residential common shares of beneficial interest beneficially owned by the Reporting Person as of the date of the original Form 3, which was overreported. Except as set forth in this amendment, the original Form 3 filed on August 18, 2026 is unchanged. Such common shares were also overreported on one Form 4 filed by the Reporting Person after his original Form 3 was filed.

Footnote F2

Pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated as of May 20, 2026, by and among AvalonBay Communities, Inc., a Maryland corporation ("AVB"), Vivmark Residential (f/k/a Equity Residential), a Maryland real estate investment trust ("VMRK"), ERP Operating Limited Partnership, an Illinois limited partnership (the "Operating Partnership"), and Canopy Merger Sub LLC, a Maryland limited liability company ("Merger Sub"), AVB and VMRK combined in a merger of equals on August 17, 2026, with AVB merging with and into Merger Sub, with Merger Sub surviving as a wholly owned subsidiary of VMRK (the "Merger"). Merger Sub subsequently merged with and into the Operating Partnership, with the Operating Partnership continuing as the surviving entity.

Footnote F3

At the effective time of the Merger (the "Effective Time"), each issued and outstanding share of common stock, par value $0.01 per share (the "AVB Common Stock"), of AVB and deferred stock unit held by the Reporting Person was automatically converted into the right to receive 2.793 (the "Exchange Ratio") common shares of beneficial interest, $0.01 par value per share ("VMRK Common Shares"), of VMRK, plus, in the case of AVB Common Stock, the right to receive cash in lieu of fractional VMRK Common Shares, if any, into which such AVB Common Stock would have been converted.

Footnote F4
