Not that I think it will make much difference but probably the 120th day is actually tomorrow, June 5th, assuming that the "Feasiblity Notice" was delivered by hand on February 4, 2013. Under Section 18.1 of the Salazar agreement, any hand-delivered or faxed notice is deemed to be actually delivered "on the business day following the day it was delivered." If by mail, it's five business days later.
Assuming hand-delivery on February 4, 2013, the notice would therefore be deemed to be delivered on February 5, 2013. Following the usual rule that the day something is issued or done does not count in the determimination of a period in which to act, the first day of the 120 day period would have been February 6, 2013 which makes June 5, 2013, the 120th day according to my calculations.
