GENERAL TERMS AND CONDITIONS

(continued)

15.4 Operations Curtailment - Western may discontinue or curtail

receipts or deliveries of gas at any time if required in

Western's judgment by weather or the necessity for repairs,

operating changes or events of Force Majeure, as

hereinabove defined, other than capacity shortages as

specified in Section 15.6, upon such notice as is

reasonable under the circumstances. In any such

curtailment, quantities of gas deliverable under

Transportation Rate Schedules by Western to Shipper on a

firm basis shall take priority over quantities of gas

deliverable by Western to Shipper on an interruptible

basis. Firm transportation service will be curtailed on a

pro rata basis regardless of whether the shipper is using

primary or alternate points. Western and Shipper shall

operate their systems so as to provide protection to

domestic and commercial consumers being served on a firm

basis under Transportation Rate Schedules. So far as

operating conditions will permit, available natural gas

shall be dispatched in accordance with the aforementioned

priority and operating guideline, in as equitable a manner

as possible.

15.5 Curtailment Over-Run Penalty - If, during any curtailment

which Western does not terminate prior to its originally

announced expiration date, Buyer or Shipper takes, without

Western's advance approval, a quantity of natural gas in

excess of the curtailment quantity allocated to such Buyer

or Shipper, said quantity shall constitute a Curtailment

Over-Run quantity; provided however, that no gas delivered

at any point where Western has complete and unrestricted

control of gas deliveries shall be considered a Curtailment

Over-Run quantity. If Shipper or Buyer does not correct

the excess takes within 48 hours of notice by Western

thereto of such excess takes, for each MMBTU of such

Curtailment Over-Run quantity taken by such Buyer or

Shipper, that Buyer or Shipper shall pay to Western a

penalty of ten dollars ($10.00); provided, however, that

Western shall have the right, without the obligation, to

waive any penalty for a Curtailment Over-Run quantity under

this Section 15.5, to the extent that such a waiver is not

unduly discriminatory and if for the period for which the

penalty was incurred, deliveries to Western's other Buyers

or Shippers were not adversely affected by the taking of
