Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On March 15, 2017, the reporting person was granted 14,353 shares of restricted Common Stock that were issued pursuant to the 2013 Hannon Armstrong Sustainable Infrastructure Capital Inc. Equity Incentive Plan, as amended (the "Plan"). The shares vest on March 5, 2019.
(2) On March 15, 2017, the reporting person was granted 20,500 shares of restricted Common Stock that were issued pursuant to the Plan. The shares will vest in equal installments of one-third of the full amount on March 15, 2018, March 5, 2019 and March 5, 2020.
(3) On March 15, 2017, the reporting person was awarded up to a maximum of 41,000 Restricted Stock Units ("RSUs") under the Plan, which represent the right to receive one share of Common Stock of the issuer for each RSU at vesting. The RSUs vest on March 5, 2020 if certain absolute and relative stockholder return targets are achieved on or prior to such date. The number of RSUs to be awarded to the reporting person range from zero to 41,000 based on the Company's performance relative to the return targets. The RSUs reported on this Form 4 assume the reporting person receives the maximum possible grant. Dividend equivalents will accrue on the RSUs from the grant date, but the reporting person is not entitled to receive the dividend equivalents until the RSUs vest. The grant is being reported here for informational purposes only.
(4) These shares are held by the reporting person's significant other. The reporting person disclaims ownership other than to the extent of his pecuniary interest.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
