will not exercise any rights that it may acquire by way of subrogation under this Agreement, by any payment made hereunder or otherwise, until all the obligations of the Borrower shall have been paid or performed in full. If any amount shall be paid
to the Guarantor on account of such subrogation rights at any time when all the obligations of the Borrower hereunder shall not have been paid or performed in full, such amount shall be held in trust for the benefit of the Bank and shall forthwith
be paid to the Bank to be credited and applied upon the obligations of the Borrower hereunder, whether matured or unmatured, in accordance with the terms hereof. 
  
 (e) This guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of
the obligations of the Borrower hereunder is rescinded or is 

  

 18 

 
otherwise returned by the Bank upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as though such payment had not been made.

connection with this Agreement, the other Security Instruments, the Letter of Credit, the Bond Documents, the Project or any unrelated transaction; 
  
 (d) any statement, draft or other document presented under the Letter of Credit proving to be forged, fraudulent, invalid or insufficient
in any respect, or any statement therein being untrue or inaccurate in any respect whatsoever; 
  
 (e) the surrender, exchange or impairment of any security for the performance or observance of any of the terms of this Agreement; or

  
 (f) any other circumstance which might
otherwise constitute a defense available to, or a discharge of, the Borrower or a Guarantor, except subject to the qualification that obligations may be reinstated upon bankruptcy, notwithstanding payment in full of the Borrower’s obligations
to the Bank. 
  
 Notwithstanding the absolute obligations of the Borrower and the
Guarantor as provided above, the Bank shall be liable to the Borrower and the Guarantor as provided in Section 10.4 hereof. 
  
 Section 4.13. Waiver of Guarantor’s Claims. The Guarantor hereby waives to the fullest extent possible as and against the Borrower and its
assets any and all rights, whether at law, in equity, by agreement or otherwise, to subrogation, indemnity, reimbursement, contribution, or any other similar claim, cause of action or remedy that otherwise would arise out of the Guarantor’s
performance of its obligations to the Bank under this Agreement. The preceding waiver is intended by both the Guarantor and the Bank to be for the benefit of the Borrower, and the waiver, until the obligations are satisfied in full and the Bank has
no further liability under this Agreement or the Letter of Credit, shall be enforceable by the Borrower or any of its successors or assigns as an absolute defense to any action by the Guarantor against the Borrower or its assets which arises out of

 (d) The Guarantor
will not exercise any rights that it may acquire by way of subrogation under this Agreement, by any payment made hereunder or otherwise, until all the obligations of the Borrower shall have been paid or performed in full. If any amount shall be paid
to the Guarantor on account of such subrogation rights at any time when all the obligations of the Borrower hereunder shall not have been paid or performed in full, such amount shall be held in trust for the benefit of the Bank and shall forthwith
be paid to the Bank to be credited and applied upon the obligations of the Borrower hereunder, whether matured or unmatured, in accordance with the terms hereof.

the obligations of the Borrower hereunder is rescinded or is

otherwise returned by the Bank upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as though such payment had not been made.

in any respect, or any statement therein being untrue or inaccurate in any respect whatsoever; 
  
 (e) the surrender, exchange or impairment of any security for the performance or observance of any of the terms of this Agreement; or

  
 (f) any other circumstance which might
otherwise constitute a defense available to, or a discharge of, the Borrower or a Guarantor, except subject to the qualification that obligations may be reinstated upon bankruptcy, notwithstanding payment in full of the Borrower’s obligations
to the Bank. 
  
 Notwithstanding the absolute obligations of the Borrower and the
Guarantor as provided above, the Bank shall be liable to the Borrower and the Guarantor as provided in Section 10.4 hereof. 
  
 Section 4.13. Waiver of Guarantor’s Claims. The Guarantor hereby waives to the fullest extent possible as and against the Borrower and its
assets any and all rights, whether at law, in equity, by agreement or otherwise, to subrogation, indemnity, reimbursement, contribution, or any other similar claim, cause of action or remedy that otherwise would arise out of the Guarantor’s
performance of its obligations to the Bank under this Agreement. The preceding waiver is intended by both the Guarantor and the Bank to be for the benefit of the Borrower, and the waiver, until the obligations are satisfied in full and the Bank has
no further liability under this Agreement or the Letter of Credit, shall be enforceable by the Borrower or any of its successors or assigns as an absolute defense to any action by the Guarantor against the Borrower or its assets which arises out of
