Adjustment of Letters of Credit. If and for so long as the Concessionaire fails to cure an Event of Default arising from an Installation Default, the MTA shall be entitled (without prejudice to its other rights and remedies, including those set out in Section 18.104.22.168 (Adjustment to Inventory Allocation)) to require the Concessionaire to increase the aggregate stated amount of the Letters of Credit by an amount equal to a percentage of the Original LOC Amount (the "Shortfall-Security Amount"). The percentage used to calculate the Shortfall-Security Amount shall be equal to the percentage by which the Concessionaire shall have failed to install the number of Communication Devices required pursuant to its Required Installation obligation and to otherwise comply with all associated testing and go-live services, calculated on a cumulative basis. By way of clarifying example, if the Concessionaire were required to install one hundred (100) Communication Devices by License Year 4 and only completed seventy (70) of the Required Installations, then the percentage used to calculate the Shortfall-Security Amount would be thirty percent (30%) and the Concessionaire would be required to increase the then-current Letters of Credit by an aggregate amount equal to thirty percent (30%) of the Original LOC Amount. The MTA shall notify the Concessionaire that it is exercising its rights under this Section 22.214.171.124 (Adjustment of Letters of Credit) and, within six (6) business days of its receipt of such notice the Concessionaire shall increase the then-current Letters of Credit by the Shortfall-Security Amount. For the avoidance of doubt, if the Concessionaire has previously reduced the aggregate amount of the Letters of Credit in accordance with Section 126.96.36.199 (Reductions to LOC Amount) (the “Reduced LOC Amount”), then the Shortfall-Security Amount shall be added to the Reduced LOC Amount.
