In the event MN Airlines adds an additional aircraft to the fleet of Aircraft, that is reasonably determined by Delta to cause a material increase to Delta’s cost to provide the Services (as measured on a per Aircraft basis), Delta reserves the right to adjust the PBTH Rate for that particular additional aircraft upon thirty (30) days’ advance written notice. During such thirty (30) day notice period, upon request from MN Airlines, the parties shall negotiate in good faith to determine an alternative way of compensating Delta for the increase in cost caused by the particular additional Aircraft (such as a one-time payment from MN Airlines), provided that if mutual agreement on such alternative is not reached by the parties, the increased rate shall go into effect as one of the end of such thirty (30) day period for that particular aircraft.
