        <footnote id="F1">On February 26, 2018, Mr. Braun was awarded these restricted limited partnership units (&quot;LTIP Units&quot;) in Acadia Realty Limited Partnership (the &quot;Company&quot;). 31,482 LTIP Units shall vest as follows:equal amounts shall vest on January 6, 2019 and on each of the first, second, third and fourth anniversaries thereof, provided that Mr. Braun continues to be employed on the vesting date in question. This figure excludes LTIP Units granted under the Company's outperformance plan, the vesting of which is subject to conditions, other than the passage of time and continued employment, which are not tied solely to the marked price of an equity security of the Company. The vesting conditions for the Company's outperformance plan relate to the Company's shareholder return relative to the total shareholder return of a basket of peer group companies.</footnote>
        <footnote id="F2">This number represents the total number of LTIP Units now held by Mr. Braun and reflects an adjustment to the total LTIP Units previously reported as beneficially owned by Mr. Braun.</footnote>
