may participate in the same manner as trading occurring during the regular RTH session,
except that any order submitted during the RTH session, including but not limited to
resting orders such as stop orders, limit orders and good until cancelled (GTC) orders,
will be deemed to have expired as of the end of RTH for purposes of this End of Week
Session. Accordingly, in the event that a market participant with such an expired order
seeks to participate in the End of Week Session, a new order must be submitted.

(D) Prices for trades executed during the End of Week Session shall be reported on
public ticker services;
