Explanation of responses 9 footnotes

Footnote F1

Each restricted unit award is subject to the same time-based vesting conditions that were previously applicable to the AVB Performance Award with respect to a number of limited partnership interests in the OP designated as restricted units ("RUs"), rounded to the nearest whole number of RUs, equal to the product of (i) the number of shares of AVB Common Stock subject to such AVB Performance Award, determined by deeming any performance-based vesting criteria applicable to such AVB Performance Award to be achieved based on the greater of target performance and the actual level of performance (which was calculated as of the latest practicable date prior to the Effective Time and certified by the Compensation Committee of the AVB board prior to the Effective Time) and (ii) 2.793.

Footnote F2

Pursuant to the Agreement and Plan of Merger, dated as of May 20, 2026 (the "Merger Agreement"), 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 "OP"), 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 OP, with the OP continuing as the surviving entity.

Footnote F3

Pursuant to the Merger Agreement, each award outstanding immediately prior to the effective time of the Merger (the "Effective Time") with respect to shares of common stock, par value $0.01 per share (the "AVB Common Stock"), of AVB that vest on the basis of the achievement of applicable performance goals (each, an "AVB Performance Award") was converted into a restricted unit award, in lieu of VMRK restricted shares.

Footnote F4

The RUs reflected in this report also include any OP Units into which such RUs automatically convert.
