NOW, THEREFORE,
in consideration of the mutual agreements, provisions and covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:


1.               
Amendments. Subject to the satisfaction of the conditions precedent set forth in Section
4 hereof, as of the Effective Date, the Borrower, the other Loan Parties, the Administrative Agent and the Signatory Lenders,
who constitute the Required Lenders, hereby agree that the Credit Agreement is amended as follows:


(a)       Section
1.01 of the Credit Agreement is amended by amending and restating the following definition:


“Debt Service Reserve Funding
Amount” means, in respect of Loans funded on each Funding Date, interest that is payable on such Loans in accordance
with Section 2.08 for the period between such Funding Date and January 31, 2022 (excluding any interest that may be paid in kind
(in lieu of payment in cash) in accordance with Section 2.08(c)).


2.

3.               
Representations and Warranties. Each Loan Party hereby represents and warrants and
warrants to the other parties hereto that: 


(a)             
Each Loan Party has full corporate, limited liability company or other organizational powers,
authority and legal right to enter into, deliver and perform its respective obligations under this Amendment to which it is a party,
and has taken all necessary corporate, limited liability company or other organizational action to authorize the execution, delivery
and performance by it of this Amendment to which it is a party. This Amendment has been duly executed and delivered by the Loan
Parties, is in full force and effect and constitutes a legal, valid and banding obligation of the Loan Parties, enforceable against
such Loan Party in accordance with its respective terms, except as enforcement may be limited (i) by Bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or other similar laws affecting creditors’ rights generally, (ii) by general principles
of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) implied covenants
of good faith and fair dealing. 


(b)            
The execution, delivery and performance by each Loan Party of this Amendment does not and
will not (i) conflict with the Organizational Documents of such Loan Party, (ii) conflict with or result in a breach of, or constitute
a default under, any indenture, loan agreement, mortgage, deed of trust or other instrument or agreement to which such Loan Party
is a party or by which it is bound or to which




     2


     


    

such Loan Party’s property or
assets are subject (other than any Material Project Document to which such Loan Party is a party), except where such contravention
or breach could not reasonably be expected to be material and adverse to the Loan Parties or Lenders, (iii) conflict with or result
in a breach of, or constitute a default under, any Material Project Document to which such Loan Party is a party, (iv) conflict
with or result in a breach of, or constitute a default under, in any material respect, any Applicable Law, except where such contravention
or breach could not reasonably be expected to have a Material Adverse Effect, or (v) with respect to each Loan Party, result in
the creation or imposition of any Lien (other than a Permitted Lien) upon any of such Loan Party’s property or the Collateral.


(c)             
Except as provided in this Amendment, no Default or Event of Default has occurred and is continuing
or would result from the transactions contemplated in this Amendment. 


(d)            
The representations and warranties of each of the Loan Parties set forth in Article III of
the Credit Agreement and in each other Financing Document are true and correct in all material respects (except where already qualified
by materiality or Material Adverse Effect, in which case, such representations and warranties are true and correct in all respects)
on and as of the Effective Date (unless stated to relate solely to an earlier date, in which case such representations and warranties
were true and correct as of such earlier date). 


4.               
Effectiveness; Conditions Precedent. This Amendment shall become effective on the date
when it shall have been executed by the Administrative Agent, the Loan Parties and the Required Lenders and when the Administrative
Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto
(such date, the “Effective Date”).


5.               
Miscellaneous.


(a)             
Effect of Amendments. From and after the Effective Date, the Credit Agreement shall
be construed after giving effect to the amendment set forth in Section 1 hereto and all references to the Credit Agreement
in the Financing Documents shall be deemed to refer to the Amended Credit Agreement.


(b)            
No Other Modification. Except as expressly modified by this Amendment, the Credit Agreement
and the other Financing Documents are and shall remain unchanged and in full force and effect, and nothing contained in this Amendment
shall, by implication or otherwise, limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of the Lenders,
the Administrative Agent, or any of the other parties, or shall alter, modify, amend or in any way affect any of the other terms,
conditions, obligations, covenants or agreements contained in the Credit Agreement which are not by the terms of this Amendment
being amended, or alter, modify or amend or in any way affect any of the other Financing Documents.


(c)             
Successor and Assigns. This Amendment shall be binding upon and inure to the benefit
of the parties to this Amendment and their respective successors and permitted assigns.


(d)            
Incorporation by Reference. Sections 10.07 (Severability), 10.11 (Headings),
10.09 (Governing Law; Jurisdiction; Etc.) and 10.17 (Electronic Execution of Assignments and Certain Other Documents)
of the Credit Agreement are hereby incorporated by reference herein, mutatis mutandis.


(e)             
Financing Document. This Amendment shall be deemed to be a Financing Document.




     3


     


    

(f)             
 Counterparts; Integration. This Amendment may be executed in counterparts (and by
different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. The Amended Credit Agreement and the other Financing Documents to which a Loan Party is party
constitute the entire contract between and among the parties relating to the subject matter hereof and thereof and supersede any
and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Delivery of an executed
counterpart of a signature page to this Agreement by telecopy or scanned electronic transmission shall be effective as delivery
of a manually executed counterpart of this Agreement.


(g)            
Severability. Any provision of this Amendment held to be invalid, illegal or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability
without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular
provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.
