pledges to Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products

or arising, and all proceeds and products thereof.


 


Borrower acknowledges that it
previously has entered, and/or may in the future enter, into Bank Services Agreements with Bank. Regardless of the terms of any
Bank Services Agreement, Borrower agrees that any amounts Borrower owes Bank thereunder shall be deemed to be Obligations hereunder

in the Collateral granted herein (subject only to Permitted Liens that expressly have superior priority to Bank’s Lien in
this Agreement).

except for Bank Services, are satisfied in full, and (b) this Agreement is terminated, Bank shall terminate the security interest
granted herein upon Borrower providing cash collateral acceptable to Bank in its good faith business judgment for Bank Services,

the Obligations (other than inchoate liabilities, but including, without limitation, Obligations arising under the European Loan

sole cost and expense, release its Liens in the Collateral and all rights therein shall revert to Borrower.”

thereof:
