 notice by the Lender, the Trigger Event will automatically become an Event of Default (as defined in the Note). Following the occurrence of any Event of Default, the Lender may, upon written notice to the Company, (i) accelerate the Note, with the outstanding balance of the Note following application of the Trigger Effect (the “Mandatory Default Amount”) becoming immediately due and payable in cash, and (ii) cause interest on the outstanding balance of the Note beginning on the date the applicable Event of Default occurred to accrue at an interest rate equal to the lesser of 22% per annum or the maximum rate permitted under applicable law. However, certain Trigger Events, such as bankruptcy or insolvency, automatically result in an Event of Default, making the outstanding balance immediately payable at the Mandatory Default Amount without notice.
