GENERAL TERMS AND CONDITIONS

(Continued)

18. WAIVERS

18.1 Penalty Waiver. Transporter may, in exercise of its reasonable

discretion, and on a nondiscriminatory basis, waive all or a part of

any penalty which might otherwise apply. Transporter shall maintain

a record of all waivers granted. Such record shall include the

identity of Shipper and the basis for Transporter granting the

waiver and shall be available for public inspection at Transporter's

office during normal business hours.

18.2 Waiver. The failure of either Party hereto at any time to require

performance by the other Party of any provision of the Agreement

shall in no way affect the right of such Party thereafter to enforce

the same, nor shall the waiver by either Party of any breach of any

provision hereof by the other Party be taken or held to be a waiver

by such Party of any succeeding breach of such provision, or as a

waiver of the provision itself.

18.3 Transporter may waive any of its rights under this Tariff or any

obligations of Shippers under this Tariff for good cause and on a

basis which is not unduly discriminatory. No waiver shall operate

or be construed as a waiver of future rights or obligations, whether

of a like or different character.
