<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As previously reported, on September&nbsp;15, 2016, Histogenics Corporation (&#147;Histogenics&#148; or the &#147;Company&#148;) entered into a securities
purchase agreement with certain institutional and accredited investors pursuant to which the Company issued 2,653,553 shares of the Company&#146;s common stock, par value $0.01 per share (&#147;Common Stock&#148;), 24,158.8688 shares of the
Company&#146;s Series A Convertible Preferred Stock and warrants to purchase up to 13,333,334 shares of the Company&#146;s Common Stock (such warrants, along with warrants to purchase up to 133,333 shares of the Company&#146;s Common Stock issued to
the placement agent for the transaction, the &#147;2016 Warrants&#148;). The exercise price of the 2016 Warrants was $2.25 per share. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Also as previously
reported, on October&nbsp;5, 2018, Histogenics entered into an underwriting agreement with Canaccord Genuity LLC, as representative of the several underwriters, related to the public offering of 26,155,000 shares of the Company&#146;s Common Stock
and warrants (the &#147;2018 Warrants&#148;) to purchase up to 19,616,250 shares of the Company&#146;s Common Stock. The exercise price of the 2018 Warrants was $0.70 per share, subject to the Company&#146;s right pursuant to Section&nbsp;2(e) of
the 2018 Warrants to reduce the exercise price to any amount and for any period of time deemed appropriate by Board of Directors (the &#147;Board&#148;) of the Company (the &#147;Voluntary Adjustment Right&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">On February&nbsp;8, 2019, Histogenics and certain holders of the 2016 Warrants (the &#147;Participating 2016 Holders&#148;) entered into a Warrant Amendment
and Exercise Agreement (the &#147;2016 Exercise Agreement&#148;) pursuant to which Histogenics agreed to reduce the exercise price of the 2016 Warrants held by such Participating 2016 Holders from $2.25 to $0.01 per share (the &#147;2016 Reduced
Exercise Price&#148;) in consideration for the exercise of the 2016 Warrants held by such Participating 2016 Holders in full at the 2016 Reduced Exercise Price for cash and provided a general release of claims of such Participating 2016 Holders
against the Company with respect to the 2016 Warrants. The Company also agreed to modify the reference to &#147;three (3)&nbsp;Trading Days&#148; in the first sentence of Section&nbsp;2(d)(i) of the 2016 Warrants held by the Participating 2016
Holders to say &#147;two (2)&nbsp;Trading Days.&#148; The Participating 2016 Holders own, in the aggregate, 2016 Warrants to purchase a total of 12,957,953 shares of the Company&#146;s Common Stock. The Company expects to receive aggregate gross
proceeds of approximately $129,579.53 from the exercise of the 2016 Warrants by the Participating 2016 Holders pursuant to the 2016 Exercise Agreement. After the full exercise of the 2016 Warrants held by the Participating 2016 Holders, 2016
Warrants to purchase approximately 508,714 shares of the Company&#146;s Common Stock will remain outstanding. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">On February&nbsp;8, 2019, pursuant to the
Voluntary Adjustment Right, Histogenics determined to reduce the exercise price of the 2018 Warrants from $0.70 to $0.01 per share (the &#147;2018 Reduced Exercise Price&#148;) through the close of business on February&nbsp;8, 2019. Additionally, on
February&nbsp;8, 2019, Histogenics and all of the holders of the 2018 Warrants (the &#147;Participating 2018 Holders&#148; and, together with the Participating 2016 Holders, the &#147;Holders&#148;) entered into a Warrant Exercise Agreement (the
&#147;2018 Exercise Agreement&#148;) pursuant to which in consideration for the 2018 Reduced Exercise Price, the Participating 2018 Holders agreed to exercise the 2018 Warrants held by such Participating 2018 Holders in full at the 2018 Reduced

Agreement. After the full exercise of the 2018 Warrants held by the Participating 2018 Holders, no 2018 Warrants remain outstanding. </P>

4.99% or 9.99% beneficial ownership limitations as set forth in the 2016 Warrants and 2018 Warrants (&#147;Beneficial Ownership Limitation&#148;), then the Company will only issue such number of shares to such Holder as instructed by such Holder and
as would not cause such Holder to exceed the maximum number of shares permitted under the Beneficial Ownership Limitation, with the balance of shares to be held in abeyance until the balance may be issued in compliance with such limitations. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Also as previously reported on December&nbsp;21, 2018, the Board initiated a process to evaluate strategic alternatives to maximize value for all
stakeholders. As part of the ongoing process, the Board is evaluating the full range of potential strategic alternatives, which includes, but is not limited to, acquisitions, business combinations, joint ventures, public and private capital raises,
recapitalization, and sale transaction options, including a sale of assets or intellectual property. The 2016 Exercise Agreements and 2018 Exercise Agreements eliminate a significant economic liability embedded in the 2016 Warrants&#146; and 2018
Warrants&#146; Black-Scholes provisions applicable in the event of a Fundamental Transaction (as defined in the 2016 Warrants and 2018 Warrants). The 2016 Exercise Agreements and 2018 Exercise Agreements are intended to achieve a cleaner capital
structure for Histogenics that, among other things, enables the Company to evaluate a broader range of potential strategic alternatives and to continue to move forward with its ongoing strategic alternatives process. </P>

exercise of the 2016 Warrants and the merits and risks of investing in the Warrant Shares, the terms and conditions of the offering of the Warrant Shares and the merits and risks of investing in the Warrant Shares; (ii)&nbsp;access to information

Shares, including, without limitation, (x)&nbsp;information known by principals and employees of the Company in their capacities as directors, officers, significant stockholders and/or affiliates of the Company, and (y)&nbsp;other confidential
Information of the Company, and that the Company is unable to disclose the Information to the Holder. The Holder understands, based on its experience, the disadvantage to which the Holder is subject due to the disparity of information between the
Company and the Holder. Notwithstanding such disparity, the Holder has deemed it appropriate to enter into this Agreement and to consummate the transactions contemplated herein. </P>

Holder to exceed the beneficial ownership limitations (&#147;<U>Beneficial Ownership Limitation</U>&#148;) in the 2018 Warrants, the Company shall only issue such number of Warrant Shares to the Holder (as instructed in writing by Holder) that would
not cause such Holder to exceed the maximum number of Warrant Shares permitted thereunder with the balance to be held in abeyance until the balance (or portion thereof) may be issued in compliance with such limitations. Holder shall provide a
written notice of deemed exercise pursuant to the terms of the 2018 Warrants, as modified hereby, to the Company promptly when any additional Warrant Shares may be issued in compliance with the Beneficial Ownership Limitation (including, without
limitation, with respect to the balance of the Warrant Shares when the Holder holds less than the Beneficial Ownership Limitation). </P>
