In addition, each option and common share purchase warrant of Northern Empire outstanding immediately prior to the effective time of the Arrangement will automatically vest and will be transferred to the Purchaser in exchange for that number of Coeur Shares as is equal to the value of the "in-the-money" amount of the options and warrants, as applicable, minus any withholding taxes required to be withheld.

Closing of the Arrangement remains subject to court approval as well as other customary closing conditions. Assuming the timely completion of these conditions, Northern Empire expects the Arrangement to close on or about October 1, 2018.
