ARTICLE III – RATE

1. Except where a Negotiated Rate or Negotiated Rate Formula

is applicable, for each Dth of Scheduled Equivalent Quantity on

any day, Shipper agrees to pay and shall pay the applicable

Maximum Hub Service Commodity Rate specified in HUB Rate Schedule

as in effect on the day the Hub Service is rendered; provided,

however, that in the event that Transporter determines, in its

sole discretion, to render Hub Service on behalf of Shipper for a

Discounted Hub Service Commodity Rate, Transporter shall notify

Shipper in writing of the amount of such Discounted Hub Service

Commodity Rate, the day(s) on which such rate shall be in effect

and the quantities to which such rate applies. For each Dth of

Scheduled Equivalent Quantity to which a Discounted Hub Service

Commodity Rate applies, as set forth in Transporter’s notice,

Shipper agrees to pay and shall pay the applicable Discounted Hub

Service Commodity Rate in lieu of the Maximum Hub Service

Commodity Rate. For each Dth of Scheduled Equivalent Quantity to

which a Negotiated Rate or a rate under a Negotiated Rate Formula

applies, Shipper agrees to pay and shall pay any applicable

Negotiated Rate or rate under a Negotiated Rate Formula set forth

in the currently effective Schedule 2 appended hereto in lieu

of the Maximum Hub Service Commodity Rate.

2. For each Dth of Scheduled Equivalent Quantity on any day,

Shipper agrees to pay and shall pay the applicable ACA

Adjustments, Deferred Asset Surcharge and any other applicable

surcharge specified in the HUB Rate Schedule as in effect on the

day the transportation service is rendered.

3. For each Dth of the Loan Balance held for Shipper’s

account each day on Transporter’s System, Shipper agrees to pay

and shall pay the applicable Maximum Daily Balance Rate

specified in Rate Schedule HUB as in effect on the day the Hub

Service is rendered; provided, however, that in the event that

Transporter determines, in its sole discretion, to render Hub

Service system-wide at a Discounted Daily Balance Rate,

Transporter shall post the amount of such Discounted Daily

Balance Rate, the day(s) on which such rate shall be in effect

and the quantities to which such rate applies on its Electronic

Bulletin Board. Such discounted rates may vary on a daily basis.

For each Dth of the Loan Balance to which a Discounted Daily

Balance Rate applies, as set forth on Transporter’s Electronic

Bulletin Board, Shipper agrees to pay and shall pay the

applicable Discounted Daily Balance Rate in lieu of the Maximum

Daily Balance Rate.

4. Shipper agrees that Transporter shall have the unilateral

right to file with the FERC and make changes effective in (a) the

rates and charges applicable to service pursuant to Transporter’s

Rate Schedule HUB, or (b) any provision of the General Terms and

Conditions applicable to such rate schedule. Transporter agrees

that Shipper may contest any such filing or changes and may

request the FERC to determine just and reasonable rates and/or

terms or conditions of service for Transporter when it believes

Transporter’s rates and/or terms or conditions of service may be

unjust, unreasonable, unduly discriminatory or preferential.
