(a) PRICING

(1) The availability and pricing of services on Natural's

system is governed by this Tariff. From time to time, Natural changes

or updates its Tariff by filings with the FERC. Each Shipper is

notified by Natural of such filings and is provided a copy of each

filing.

(2) Telephone inquiries related to the availability or

pricing of services are answered by representatives of Natural and upon

request, potential Shippers are provided copies of Natural's Tariff

filings.

(3) Shippers desiring a rate under any Agreement other

than the maximum rate on file with the FERC are required to submit such

requests in writing or by electronic medium to the Director,

Transportation/Storage Services, in Houston. Any lower rate agreed to

by Natural is evidenced in writing to such Shipper, and such rate is

considered confidential until it is reported to the FERC as required by

the Regulations. In order to attract or determine interest in the use

of any particular service, representatives of Natural may from time to

time contact Shippers by telephone, to the extent consistent with

Section 5.1(e) of these General Terms and Conditions. Such

conversations are confidential and may or may not result in Shipper

submitting a request for a discounted rate for a particular service.
