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 29,620 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 63,160 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 189,480 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 189,480 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 Jeffrey W. Eckel Revocable Trust, of which Jeffrey W. Eckel is the sole trustee and beneficiary.
(5) The reporting person acts as custodian for his grandson under the Uniform Gifts to Minors Act. The reporting person disclaims beneficial ownership of these securities, and this report shall not be deemed an admission that the reporting person is the beneficial owner of such securities for purposes of Section 16 or for any other purpose.
