GENERAL TERMS AND CONDITIONS

25. PROVISIONS APPLICABLE ONLY TO RATE SCHEDULES SS-1 AND SS-2 (Cont'd.)

25.11 Storage Field Losses (Cont'd.)

Shipper is placed on notice that Transporter may recognize

storage gas losses for rate and accounting purposes. Such losses

shall be valued at the current replacement cost of gas. After

accounting recognition of any such loss, Transporter shall record

and maintain a regulatory asset account which shall be maintained

until Transporter's next general rate change filing under Section

4 of this Natural Gas Act. In any of Transporter's general rate

change filings, Transporter may propose to amortize storage gas

losses through its base rates. This provision shall apply to

storage gas losses incurred by unamortized as of the date upon

which this provision becomes effective, and to those incurred

after that date.

25.12 Waiver of Defaults

No waiver by either Transporter or Buyer of any one or more

defaults by the other in the performance of any provisions of

this Tariff, the applicable Rate Schedule and the Service

Agreement shall operate or be construed as a waiver of any future

default or defaults, whether of a like or of a different

character, or of the continued enforceability of any of the

provisions thereof.

25.13 Buyer's Liabilities

Buyer shall not be relieved of its obligations to pay the Minimum

Bill rendered each month until the service agreement is

terminated according to its terms and, notwithstanding the

provisions of Paragraph 25.11 of these General Terms and

Conditions, Buyer's obligations to pay the Minimum Bill rendered

each month shall be unaffected by any circumstance whatsoever

unless otherwise provided in the applicable rate schedule under

this Tariff.
