Lender may now have or may have in the future under or in connection with the Canadian Loan Agreement or the other Financing Agreements including, without limitation, the exercise of any rights and remedies by any of the Agent and the Revolving
Lender.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
