If an event of default occurs, including failure to pay principal or interest due on the loan balance, a voluntary or involuntary proceeding seeking liquidation, change in control of the Company, or one or more judgments against the Company in excess of $10 million, the lenders would be entitled to accelerate the facility and take various other actions, including all actions permitted to be taken by a secured creditor. If certain bankruptcy events of default occur, the facility will automatically accelerate.
