GENERAL TERMS AND CONDITIONS

10. NOMINATIONS/CONFIRMATIONS/SCHEDULING/INTERRUPTION OF SERVICE

(Continued)

10.4 Capacity Allocation and Confirmation Process (Continued)

10.46 Timing of Confirmation

When a Confirmation Requester receives a

Confirmation Response document 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 a corresponding

Confirmation Response Quick Response document by the

conclusion of the subsequent quarter hour period.

[1.3.45]

The quarter hour periods will be defined to begin on

the hour and at 15, 30 and 45 minutes past the hour.

A given quarter hour will contain all transactions

whose receipt time is less than the beginning of the

subsequent quarter hour. [1.3.45]

10.47 Departure from Confirmation Deadlines

Confirming Parties' nightly processing and routine

maintenance occurring outside normal business hours

are apt to interrupt the normal schedule of

confirmations/quick response turnaround stated in

NAESB WGQ Standard 1.3.45 (see 10.46). Such delays

shall be kept to a minimum. The normal schedule

shall be resumed at the earliest opportunity and no

later than the start of normal working hours the

following day, seven days per week. [1.3.46]

10.48 Stranded Nomination

A nomination at an in-line Transfer Point may become

isolated from its supply or market component as part

of the confirmation process.

Company will attempt to contact the Nominating Party

who has a stranded nomination to see if the Transfer

Point requested can be changed to its corresponding

physical point (no increase in transportation

mileage). If such a nomination change cannot be

made and confirmed in a timely manner, the stranded

nomination will not be scheduled.
