F2	10,246 units of limited partner interest ("OP Units") in Hannon Armstrong Sustainable Infrastructure, LP (the "Partnership") are issuable upon the vesting and conversion of 10,246 long-term incentive plan units ("LTIP Units") in the Partnership. The LTIP Units were granted to the Reporting Person under the Issuer's 2022 Equity Incentive Plan, as amended.

Upon conversion of LTIP Units into OP Units, the Reporting Person will have the right to cause the Partnership to redeem a portion of the Reporting Person's OP Units for cash in an amount equal to the market value (as defined in the Partnership Agreement) of an equivalent number of shares of common stock, par value $0.01 per share, of HA Sustainable Infrastructure Capital, Inc. (the "Issuer"), or at the Issuer's option, shares of the Issuer's common stock on a one-for-one basis, subject to certain adjustments.
