RATE SCHEDULE NSS

-----------------

5.3 (a) A Shipper's IQ shall be the maximum volume of gas

such Shipper has the right to inject on any day under the NSS

Agreement on a firm basis [subject to Section 5.7 and subsection

(b) below]. If a Shipper exceeds its firm injection rights

hereunder, such excess injections shall be subject to Overrun

Charges under Section 12 of the General Terms and Conditions of

this Tariff. A Shipper's IQ varies based on its inventory level,

as follows:

(1) When a Shipper's inventory level in its

storage account under the NSS Agreement is less than sixty-seven

percent (67%) of its MSV under the NSS Agreement, its IQ shall

equal fifty percent (50%) of its MDQ; and

(2) When a Shipper's inventory level in its

storage account under the NSS Agreement is equal to or greater

than sixty-seven percent (67%) of its MSV under the NSS Agreement,

its IQ shall equal thirty-three percent (33%) of its MDQ.

(b) (1) Subject to subsection (2) below, a Shipper's

firm injection and withdrawal rights on any day shall be further

limited as set out in this subsection. Each contract shall specify

the percentage of service to which Shipper is entitled on the

Amarillo Line (Amarillo Percentage) and the percentage of service

to which Shipper is entitled on the Gulf Coast Line (Gulf Coast

Percentage). The sum of such percentages shall be 100%. The

Amarillo Percentage times a Shipper's IQ shall be available for

injections from sources on the Amarillo Line and the Gulf Coast

Percentage times a Shipper's IQ shall be available for injections

from sources on the Gulf Coast Line. Similarly, the Amarillo

Percentage times a Shipper's WQ shall be available for withdrawal

from sources on the Amarillo Line and the Gulf Coast Percentage

times a Shipper's WQ shall be available for withdrawal from

sources on the Gulf Coast Line. Volumes which a Shipper seeks to

have scheduled and Natural is able to schedule for either

injection or withdrawal on either line in excess of the resulting

daily firm volume hereunder or in excess of the restrictions in

subsection (3) shall be treated as authorized overrun, with the

same priority as other authorized overrun injections and

withdrawals under Section 5.5(b) of this Rate Schedule NSS.
