(d) When a Confirmation Requester receives a Confirmation Response

document via EDI from a Confirming party by the conclusion of a

given quarter hour period, the Confirmation Requester will send

to the Confirming Party's designated site via EDI, a

corresponding Confirmation Response Quick Response document by

the conclusion of the subsequent quarter hour period.

The quarter hour periods will be defined to begin on the hour

hour will contain all transactions whose receipt time is less

than the beginning of the subsequent quarter hour. (NAESB

(e) Confirming Parties' nightly processing and routine maintenance

occurring outside of normal business hours are apt to interrupt

a minimum. The normal schedule should be resumed at the

earliest opportunity and no later than the start of normal

working hours the following day, seven days per week. (NAESB

other provisions of this Tariff. (NAESB Standard 1.3.23)

(g) With respect to the timely Confirmation process for Daily

Nominations, at a Point of Receipt or Delivery, in the absence

of agreement to the contrary, the lesser of the confirmation
