PART 2

GENERAL TERMS AND CONDITIONS

(Continued)

9. NOMINATION, ALLOCATION AND COMMENCEMENT OF SERVICE

9.1 Nomination. When nominating quantities of gas for injection into

or withdrawal from each of the peaking storage reservoirs, shipper shall

follow the nomination procedures stated in the General Terms and Conditions of

Part 1 of this tariff.

9.2 Allocation.

(a) Shipper's allocation of gas that can be injected daily into

each peaking storage reservoir shall be calculated as follows:

INJECTION ALLOCATION = (A/B)*C

A = Shipper's annual working gas for a particular reservoir

B = Sum of the annual working gas of all PKS shippers at that

reservoir

C = Available injection 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 injection allocation at a particular reservoir, the

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

that desire additional injection 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 injection capacity that was requested by them.

Any remaining injection capacity will be available for use in providing

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 injection capacity is utilized.

(b) Shipper's allocation of gas that can be withdrawn daily

from each peaking storage reservoir shall be calculated as follows:
