GENERAL TERMS AND CONDITIONS

(Continued)

K = Maximum possible reservoir deliverability at current storage

inventory

L = Deliverability unclaimed by FSS and PAL1 shippers from the firm

withdrawal allocation

M = Deliverability attributable to PAL1 shippers' parked quantities

* = Multiplication operator

NOTE: Working gas includes Questar's reserved capacity.

If any Rate Schedule FSS shipper elects, on any day, not to utilize all

or any portion of its withdrawal allocation, the amount not used shall be

allocated to all remaining Rate Schedule FSS shippers that desire additional

withdrawal allocation by using the above formula as modified to exclude the

data related to those shippers who have received all of the withdrawal

capacity that was requested by them.

If any FSS withdrawal capacity remains after Rate Schedule FSS

allocations, it shall be available first to the PAL1 shippers according to

their contract withdrawal quantity and Part 4 of the Tariff.

If any withdrawal capacity remains after service to FSS and PAL1

shippers, it shall be allocated pro rata among the ISS shippers, up to the

level requested, based on each shippers current storage inventory. This

procedure will be continued until (1) all requests are filled or (2) all

available withdrawal capacity is utilized.

In the event there is unclaimed ISS withdrawal capacity, it shall be

made available to other shippers: first as authorized overrun service and

second as Rate Schedule PAL2 service, and allocated, to the extent necessary,

pro rata to those shippers based on their service priority contained in § 9

of the General Terms and Conditions of this part.
