Subordination Agreement
Ladies and Gentleman:
Reference is hereby made to that certain (i) Credit Agreement, dated as of February 4, 2019 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Tremont Loan Agreement”), by and between Tremont Mortgage Trust (the “Company”) and Tremont Realty Advisors LLC (the “TRA Lender”, “we” or “us”) and (ii) Master Repurchase Agreement, dated as of February 9, 2018 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Senior Loan Agreement”), by and between the TRMT CB Lender LLC (the “TRMT Borrower”) and Citibank, N.A. (the “Senior Lender”). In connection with the Senior Loan Agreement, the Company guaranteed the obligations of the TRMT Borrower under the Senior Loan Agreement. 
Subordination of Tremont Loan Agreement
Furthermore, we agree, as the TRA Lender, for good and valuable consideration, the receipt and sufficiency of which hereby are acknowledged, for the benefit of the parties hereto and all future assignees or transferees under the Senior Loan Agreement, that the right of the TRA Lender (and any transferee or assignee thereof) to repayment of any obligations under the Tremont Loan Agreement shall be subordinated to the prior repayment in full of all obligations under the Senior Loan Agreement, to the extent provided herein.  
Notwithstanding any other agreements heretofore entered into between us and the Company or any third party relating to the Tremont Loan Agreement, we hereby agree, for ourselves and any of our assignees or transferees under the Tremont Loan Agreement, that if at any time an Insolvency Event (as defined below) occurs, any payment or distribution of any kind or character, whether in cash, property or securities, would be payable or deliverable to the TRA Lender (or such assignee or transferee), such payment or distribution shall instead be paid over or delivered to the Senior Lender, and the TRA Lender (or such assignees or transferees, as applicable) shall not receive any such payment or distribution or any benefit therefrom unless and until all obligations (other than contingent indemnification obligations as to which no claim has been made) under the Senior Loan Agreement have been paid in full in cash (or otherwise to the written satisfaction of the Senior Lender) and the Senior Loan Agreement has been terminated. Should any payment or distribution in respect of the Tremont Loan Agreement be collected or received by the TRA Lender or any of its assignees or transferees in contravention of the subordination provision described above, the TRA Lender or any such assignees or transferees, as applicable, shall forthwith turn over the same to the Senior Lender in the form received (with necessary endorsements or assignments, if applicable) and, until so turned over, shall hold the same in trust for the Senior Lender as their property. For purposes of this letter agreement, an “Insolvency Event” shall mean the adoption by the Company of a plan of liquidation, dissolution or winding up of the Company's affairs or the entry or filing by the Company into a voluntary petition, or the filing against the Company or its properties or assets of an involuntary petition, for bankruptcy, receivership or other similar proceeding.

1

In addition to the foregoing, we further agree, for the benefit of the parties hereto and all future assignees or transferees under the Senior Loan Agreement, that (i) neither the TRA Lender nor any of its assignees or transferees, as applicable, shall take any actions or agree to take any actions to amend or waive any provision of the Tremont Loan Agreement in any manner that conflicts with the provisions set forth herein and (ii) to the extent any payment with respect to the obligations under the Senior Loan Agreement (whether by or on behalf of the Company, as proceeds of security, enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential in any respect, set aside or required to be paid to a debtor in possession, trustee, receiver or similar person, then the obligation or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred (and if this letter agreement shall have been terminated prior to such refund or repayment, this letter agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto). The rights of the Senior Lender to enforce subordination as herein provided shall not at any time in any way be prejudiced or impaired by any act or failure to act by the Senior Lender, or by any noncompliance by the Company with the terms and provisions herein, regardless of whether the Senior Lender has, or may otherwise be charged with, knowledge thereof.
This letter agreement and the rights and obligations of the parties under this Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York, and shall be binding upon the parties and their respective successors, transferees and assigns. THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY CIVIL ACTION OR PROCEEDING ARISING OUT OF, OR BASED UPON, THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.  We agree not to transfer any of our loans or other rights or interests under the Tremont Loan Agreement unless the assignee or transferee agrees in writing to be bound by this letter agreement.  Any attempted transfer in violation of the foregoing sentence shall be of no effect and null and void, regardless of whether the purported transferee has any actual or constructive knowledge of the transfer restrictions set forth in this letter agreement, and shall not be recorded on the transfer books of the Company.

 Exhibit 10.1 

WARRANT AMENDMENT AND EXERCISE AGREEMENT 

This Warrant Amendment and Exercise Agreement (this “Agreement”), dated as of February 8, 2019, is by and between
Histogenics Corporation, a Delaware corporation (the “Company”), and the undersigned holder (the “Holder”) of warrants to purchase shares of the Company’s common stock, par value $0.01 per share (the
“Common Stock”). 
 WHEREAS, the Holder beneficially owns warrants to purchase in the aggregate the number of shares of
Common Stock with an exercise price of $2.25 per share that are exercisable until November 22, 2021, as set forth on the Holder’s signature page hereto (the “2016 Warrants”); 

WHEREAS, in order to induce the Holder to fully exercise the 2016 Warrants, the Company and the Holder desire to amend the 2016 Warrants to
reduce the exercise price thereof to $0.01 per share (the “Amended Exercise Price”), provided that the 2016 Warrants are exercised prior to February 8, 2019; and 

WHEREAS, the Holder desires to fully exercise such 2016 Warrants in the amounts set forth on the applicable signature pages hereto using the
Amended Exercise Price. The shares of Common Stock underlying the 2016 Warrants are referred to herein as the “Warrant Shares”. 

NOW, THEREFORE, IN CONSIDERATION of the mutual covenants contained in this Agreement, and for good and valuable consideration the receipt and
adequacy of which are hereby acknowledged, the Holder and the Company agree as follows: 
 ARTICLE I 

AMENDMENT AND EXERCISE OF 2016 WARRANTS 

Section 1.1 Amendment of 2016 Warrants. 

(a)    On the date hereof, (x) the reference to “$2.25 per share” in the defined term “Exercise
Price” set forth in Section 2(b) of the 2016 Warrants shall be amended to equal “$0.01 per share, provided that this Warrant is exercised prior to February 12, 2019, otherwise such Exercise Price shall be $2.25 per share”
(the “Amended Exercise Price”) and (y) the reference to “three (3) Trading Days” in the first sentence of Section 2(d)(i) of the 2016 Warrants shall be amended to say “two (2) Trading Days”.

 (b)    All references to the 2016 Warrants used herein, after the execution of this Agreement, shall refer to the
2016 Warrants, as amended pursuant to clause (a) above. Except as expressly set forth in this Agreement, all terms of the 2016 Warrants are, and shall continue to be, in full force and effect and are hereby ratified and confirmed in all
respects, and the Holder reserves all of its rights, remedies, powers and privileges. 
 Section 1.2 Exercise of Warrants.
Subject to the conditions in Sections 2(a) and (d) of each of the 2016 Warrants and the terms hereof, by executing this Agreement, the Company and the Holder hereby agree that the Holder shall be deemed to have exercised the 2016 Warrants held
by such Holder for the number of shares of Common Stock set forth on the signature page hereto for aggregate cash proceeds to the Company in the amount set forth on the Holder’s signature page hereto, pursuant to the terms of the 2016 Warrants,
except that the exercise price thereunder shall be the Amended Exercise Price and the Warrant Share Delivery Date shall be two (2) Trading Days. The Holder shall deliver the aggregate cash exercise price for such 2016 Warrants to the bank
account set forth on the Company’s signature page hereto within two Trading Days after the date hereof and the Company shall cause its transfer agent to deliver the Warrant Shares, without any restricted legend or other restrictions on
transfer, to the Holder via the Depository Trust Company Deposit or Withdrawal at Custodian system pursuant to the terms of the 2016 Warrants (as amended pursuant to this Agreement) and the DWAC instructions set forth on the Holder’s signature
page hereto as if a notice of exercise (subject to reduction for the Beneficial Ownership Limitation (as defined below)) with respect thereto was delivered to the Company on the date hereof. The date of the closing of the initial exercise of the
2016 Warrants shall be referred to as the “Closing Date.” Notwithstanding anything herein to the contrary, in the event that the exercise of the 2016 Warrants would otherwise cause the Holder to exceed the beneficial ownership
limitations (“Beneficial Ownership Limitation”) in the 2016 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 2016 Warrants, as amended 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). 

Section 1.3 Filing of Form 8-K. Prior to 9:30 am ET on February 8, 2019, the Company
shall issue a Current Report on Form 8-K disclosing the material terms of the transactions contemplated hereby, which shall include this form of Agreement as an exhibit (the “8-K Filing”). From and after the issuance of the 8-K Filing, the Company represents to the Holder that it shall not be in possession of any material, nonpublic
information received from the Company, any of its Subsidiaries (as defined below) or any of their respective officers, directors, employees or agents, that is not disclosed in the 8-K Filing. In addition,
effective upon the filing of the 8-K Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any
of its Subsidiaries or any of their respective officers, directors, employees or agents, on the one hand, and the Holder or any of its affiliates, on the other hand, shall terminate. The Company shall not, and shall cause each of its Subsidiaries
and its and each of their respective officers, directors, employees and agents, not to, provide the Holder with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the date hereof without the express
prior written consent of the Holder. To the extent that the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, delivers any material, non-public information
to the Holder without the Holder’s consent, the Company hereby covenants and agrees that the Holder shall not have any duty of confidentiality with respect to, or a duty not to trade on the basis of, such material, non-public information. As used herein, “Subsidiary” means any subsidiary of the Company, and shall, where applicable, also include any direct or indirect subsidiary of the Company formed or
acquired after the date hereof. 
 Section 1.4 Filing of Prospectus Supplement. Contemporaneously with the filing of the 8-K Filing reference in Section 1.3 above, the Company shall also file a prospectus supplement to the registration statement on Form S-3 (File No. 333-213980) (the “Registration Statement”) disclosing the Amended Exercise Price of the 2016 Warrants (the “Prospectus Supplement”). 

Section 1.5 Mutual Release. Each party hereto on behalf of itself and its affiliates (collectively, the “Releasing
Parties”) hereby unconditionally release and forever discharge the other party hereto, including, but not limited to, all of such other party’s present and former subsidiaries, affiliate companies, shareholders, officers, directors,
employees, attorneys and agents, from any and all causes of action, demands, claims, contracts, encumbrances, liabilities, obligations, expenses, losses, and rights of every nature and description, whether arising or pleaded in law or in equity,
under contract, statute, tort or otherwise, whether known or unknown, whether accrued, potential, inchoate, liquidated, contingent or actual, asserted or that might have been asserted which the Releasing Parties now have, have ever had or may
hereafter have, accruing or arising contemporaneously with, or before the date hereof, based upon or arising out of the 2016 Warrants. The Holder agrees that none of the Company nor its present and former subsidiaries, affiliate companies,
shareholders, officers, directors, employees, attorneys and agents shall have any liability to the Holder’s Releasing Parties, whatsoever due to or in connection with the Company’s use or
non-disclosure of the Information (as defined in Section 2.2(d)) or otherwise as a result of the transactions contemplated herein, and the Holder hereby irrevocably waives any claim that it might have
based on the failure of the Company to disclose the Information. For the avoidance of doubt, this mutual release shall not release any Releasing Party of its obligations, if any, under this Agreement, in connection with the Shares or any other
agreement by and between the Company and the Holder. 

 ARTICLE II 

REPRESENTATIONS AND WARRANTIES 

Section 2.1 Representations and Warranties of the Company. The Company hereby makes the representations and warranties set forth
below to the Holder that as of the date of its execution of this Agreement: 
 (a)    Authorization; Enforcement.
The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of this
Agreement by the Company and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary action on the part of such Company and no further action is required by such Company, its board of directors or
its stockholders in connection therewith other than in connection with the filings required pursuant to Section 1.3 of this Agreement. This Agreement has been duly executed by the Company and, when delivered in accordance
with the terms hereof will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms except (i) as limited by general equitable principles and applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable
remedies. 
 (b)    Organization. The Company is a duly organized and validly existing corporation in good
standing under the laws of the State of Delaware. 
 (c)    Registration Statement. The Warrant Shares are
registered for resale on the Registration Statement and the Company knows of no reasons why such registration statement (following the filing of the Prospectus Supplement) shall not remain available for the resale of such Warrant Shares for the
foreseeable future. The Company shall use commercially reasonable efforts to keep the Registration Statement effective and available for the resale of the Warrant Shares underlying the 2016 Warrants until all Warrant Shares have been sold thereunder
or are sold under Rule 144 of the Securities Act of 1933, as amended (the “Securities Act”). If the Company is unable to keep the Registration Statement effective and available through such time despite their commercially reasonable
efforts, either the Company or the Holder may, by delivering written notice to the other, terminate all remaining obligations under this Agreement. 

(d)    No Conflicts. The execution, delivery and performance of this Agreement by the Company and the consummation
by the Company of the transactions contemplated hereby do not and will not: (i) conflict with or violate any provision of the Company’s certificate of incorporation, bylaws or other organizational or charter documents, or
(ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, result in the creation of any lien upon any of the properties or assets of the Company, or give to others any
rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any material agreement, credit facility, debt or other material instrument (evidencing Company debt or otherwise) or other material
understanding to which the Company is a party or by which any property or asset of the Company is bound or affected, or (iii) conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other
restriction of any court or governmental authority to which the Company is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company is bound or affected, except in the case of each of
clauses (ii) and (iii), such as would not have or reasonably be expected to result in (i) a material adverse effect on the legality, validity or enforceability of this Agreement, (ii) a material adverse effect on the results of
operations, assets, business or condition (financial or otherwise) of the Company and its subsidiaries, taken as a whole, or (iii) a material adverse effect on the Company’s ability to perform in any material respect on a timely basis its
obligations under this Agreement (any of (i), (ii) or (iii), a “Material Adverse Effect”). 

(e)    Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by
this Agreement, the Company confirms that neither it nor any other Person acting on its behalf has provided any of Holder or their agents or counsel with any information that it believes constitutes or might constitute material, non-public information. The Company understands and confirms that the Holder will rely on the foregoing representation in effecting transactions in securities of the Company. As of the date of this Agreement, all of
the disclosure when furnished by or on behalf of the Company to the Holder regarding the Company and its Subsidiaries, their respective businesses and the transactions contemplated hereby, including but not limited to the disclosure set forth in the
SEC Reports, is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not
misleading. As used herein, “SEC Reports” means 

 
all reports, schedules, forms, statements and other documents required to be filed by the Company as of the date of this Agreement with the Commission pursuant to the reporting requirements of
the Securities Exchange Act of 1934, as amended, including all exhibits included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein. 

Section 2.2 Representations and Warranties of the Holder. The Holder hereby makes the representations and warranties set forth
below to the Company that as of the date of its execution of this Agreement. 
 (a)    Organization; Due
Authorization. The Holder is either an individual or an entity duly incorporated or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership,
limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder. The Holder represents and warrants that (i) the
execution and delivery of this Agreement by it and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary action on its behalf and (ii) this Agreement has been duly executed and delivered by
the Holder and constitutes the valid and binding obligation of the Holder, enforceable against it in accordance with its terms. 

(b)    Understandings or Arrangements. The Holder is acquiring the Warrant Shares as principal for its own account
and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Warrant Shares (this representation and warranty not limiting the Holder’s right to sell the Warrant Shares
pursuant to a registration statement or otherwise in compliance with applicable federal and state securities laws). The Holder is acquiring the Warrant Shares hereunder in the ordinary course of its business. 

(c)    No Conflicts. The Holder represents and warrants that the execution, delivery and performance of this
Agreement by the Holder and the consummation by the Holder of the transactions contemplated hereby do not and will not: (i) conflict with or violate any provision of the Holder’s organizational or charter documents, or (ii) conflict
with or result in a violation of any agreement, law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority which would interfere with the ability of the Holder to perform its obligations
under this Agreement. 
 (d)    Access to Information. The Holder acknowledges that it has had the opportunity to
review this Agreement and the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the
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) access to information
about the Company and its general affairs, business, prospects, management, assets, stockholders’ equity, results of operations or financial condition (collectively, the “Information”) sufficient to enable it to evaluate its
investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the
investment. The Holder acknowledges and agrees that neither Canaccord Genuity LLC (the “Advisor”) nor any affiliate of the Advisor has provided the Holder with any information or advice with respect to the Warrant Shares. Neither
the Advisor nor any affiliate has made or makes any representation as to the Company or the quality of the securities issuable hereunder and the Advisor and any affiliate may have acquired non-public
information with respect to the Company which the Holder agrees need not be provided to it. In connection with the issuance of the securities hereunder to the Holder, neither the Advisor nor any of its affiliates has acted as a financial advisor or
fiduciary to the Holder. The Holder acknowledges and understands that (w) the Company may possess material nonpublic information regarding the Company not known to the Holder that may impact the value of the 2016 Warrants and the Warrant
Shares, including, without limitation, (x) 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) 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. 

 (e)    Holder Status. The Holder represents and warrants that at
the time the Holder was offered the Warrant Shares, it was, and as of the date hereof it is, an “accredited investor” as defined in Rule 501 under the Securities Act. 

(f)    Knowledge. The Holder, either alone or together with its representatives, has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Warrant Shares, and has so evaluated the merits and risks of such investment. The Holder is able to bear the
economic risk of an investment in the Warrant Shares and, at the present time, is able to afford a complete loss of such investment.

this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree

such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.
