        <footnote id="F1">The Class I-R Operating Partnership Units (formerly designated Class I Operating Partnership Units) (&quot;Class I-R OP Units&quot;) were acquired by the reporting person on February 1, 2023 as consideration for the redemption of his interest in a limited partnership. No cash consideration was paid. Beginning on January 1, 2024, the reporting person became eligible to request that AIREIT Operating Partnership LP, a subsidiary of the Issuer (the &quot;Operating Partnership&quot;), redeem all or a portion of the Class I-R OP Units for cash, unless the Issuer determines that redemption for cash would be prohibited by applicable law, the Issuer's charter, or the Operating Partnership's limited partnership agreement (&quot;OP Agreement&quot;), in which case the Class I-R OP Units would be redeemed for shares of the Issuer's Class I-R common stock (formerly designated Class I common stock), subject to any limitations on redemption in the OP Agreement.</footnote>
        <footnote id="F2">The Issuer approved the Reporting Person's request that the Operating Partnership redeem 200,118.066 Class I-R OP Units for cash, effective as of February 28, 2025. The Class I-R OP Units were priced at the then-current net asset value of such Class I-R OP Units as of February 28, 2025, or $12.8086 per Class I-R OP Unit.</footnote>
        <footnote id="F3">There is no expiration date for the reporting person's ability to request redemption of the Class I-R OP Units.</footnote>
