 (c) The commencement by Borrower of any case, proceeding, or other action seeking reorganization, arrangement, adjustment, liquidation,
dissolution, or composition of its debts under any law relating to bankruptcy, insolvency, or reorganization, or relief of debtors, or seeking appointment of a receiver, trustee, custodian, or other similar official for it or for all or any
substantial part of its property; 
  
 (d) The
commencement of any case, proceeding, or other action against Borrower seeking to have any order for relief entered against it as debtor, or seeking reorganization, arrangement, adjustment, liquidation, dissolution, or composition of Borrower’s

Event of Default, provided that such Event of Default is not cured to Lender’s satisfaction in that five-day period, and in addition thereto, and not in substitution therefor, Lender shall be entitled to exercise any one or more of the rights
and remedies provided by applicable law. Failure to exercise said option or to pursue such other remedies shall not constitute a waiver of such option or such other remedies or of the right to exercise any of the same in the event of any subsequent
Event of Default hereunder. Lender shall be entitled to collect all reasonable costs and expenses of collection and/or suit, including, but not limited to, reasonable attorneys’ fees.
