RATE SCHEDULE FT-D

FIRM TRANSPORTATION SERVICE (Conditional)

5. RATES AND CHARGES (Continued)

5.8 Notwithstanding any provision of Company's effective FERC Gas Tariff to the

contrary, Company and Shipper may mutually agree in writing to rates, rate

components, charges or credits for service under this Rate Schedule that differ

from those rates, rate components, charges or credits that are otherwise

prescribed, required, established or imposed by this Rate Schedule or by any

other applicable provision of Company's effective FERC Gas Tariff. If Company

agrees to such differing rates, rate components, charges or credits

("Negotiated Rates"), then the Negotiated Rate(s) shall be effective only for

the period agreed upon by Company. During such period, the Negotiated Rate

shall govern and apply to the Shipper's service and the otherwise applicable

rate, rate component, charge or credit which the parties have agreed to replace

with the Negotiated Rate, shall not apply to, or be available to, the Shipper.

At the end of such period, the otherwise applicable maximum rates or charges

shall govern the service provided to Shipper. Only those rates, rate

components, charges or credits identified by Company and Shipper in writing as

being superseded by a Negotiated Rate shall be ineffective during the period

that the Negotiated Rate is effective; all other rates, rate components,

charges or credits prescribed, required, established or imposed by this Rate

Schedule or Company's FERC Gas Tariff shall remain in effect. Company shall

make any filings at the FERC necessary to effectuate a Negotiated Rate.

6. FUEL AND LOSSES

Shipper shall provide daily to Company, at no cost to Company, the Fuel Retention and

Loss Quantity for system fuel use and gas lost and unaccounted for, associated with

rendering transportation service pursuant to this Rate Schedule. Since fuel

reimbursement is in kind, the standard fuel calculation mechanism, as this is related

to the nomination process, shall be (1 - fuel % / 100) multiplied by receipt quantity

(in Dekatherms) = delivery quantity (in Dekatherms). [1.3.16/v1.0] The applicable

percentage is shown in the Summary of Rates and Charges in Company's effective Tariff.

7. MONTHLY BILL

The Monthly Bill for deliveries shall be equal to:

(a) Demand Charge

A Demand charge equal to the product of the applicable Demand Rate shown on the

effective Summary of Rates and Charges multiplied by the Transportation Quantity

specified in the FT-D Agreement.

(b) Commodity Charge

The applicable Commodity Rate set forth on the effective Summary of Rates and

Charges multiplied by the quantity of gas delivered in the month; and

Schedule.
