PART 2

GENERAL TERMS AND CONDITIONS

(Continued)

WITHDRAWAL ALLOCATION = (X/Y)*Z

X = Shipper's estimated recoverable working gas remaining in storage

at a particular reservoir

Y = Sum of the estimated recoverable working gas remaining of all PKS

shippers at that reservoir

Z = Available withdrawal capacity on any day at that reservoir

* = Multiplication operator

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

or any portion of its withdrawal allocation at a particular reservoir, the

amount not used shall be allocated to all remaining Rate Schedule PKS shippers

that desire additional withdrawal allocation, at that reservoir, 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 firm withdrawal capacity remains unclaimed after completion of

the above allocation procedure, it shall be available to provide parking and

loaning service under Rate Schedule PAL2 with the highest rate paid being

given the highest priority. When two or more shippers are paying the same

rate, available capacity will be allocated pro rata up to the level requested,

to those PAL2 shippers that are paying the same rate. This procedure will

continue until (1) all the requests are filled or (2) all available withdrawal

capacity is utilized.

9.3 Commencement of Service. Starting no later than 9:00 a.m. on the

day immediately following the calendar day nominations are received, Questar

will commence injecting or withdrawing quantities of gas less any appropriate

reduction for fuel reimbursement according to § 14 of this Part 2.
