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 Hannon Armstrong Sustainable Infrastructure Capital, Inc.
