If a Shipper's total unauthorized Overrun Gas quantities

under Rate Schedule EFT are less than both 50 Dth and 10% of

its Contract Limitations, Shipper shall not be assessed an

Excess Contract Quantities charge; provided, however, that

such exemption shall not be applicable in the event of

curtailment or if Transporter has invoked the provisions of

Section 20 of the General Terms and Conditions. For a

Service Month in which Excess Contract Quantities are

transported, Shipper shall be billed the sum of the products

of (x) the Excess Contract Quantities within each of the

above specified percentage ranges, multiplied by (y) the

applicable Excess Contract Quantities Rate, as specified in

Transporter's Statement of Effective Rates and Charges for

Transportation of Gas contained in this Tariff.

In the event that Transporter has invoked the provisions of

Section 20 of the General Terms and Conditions, the higher

charges shown on Transporter's Statement of Effective Rates

and Charges for Transportation of Gas for the Excess

Contract Quantities will be assessed. If Transporter has not

invoked the provisions of Section 20 of the General Terms

and Conditions, it will not assess Excess Contract

Quantities penalties until it has first given the affected

Shipper(s) twenty-four (24) hours' notice, which notice

shall be, in Transporter's sole discretion notwithstanding

any other provisions contained in this Tariff, via

facsimile, telephone (including a message via voice mail or

other messaging) or e-mail, or otherwise during the

scheduling process via the Internet. Transporter may waive

all or part of any such charges.

Imbalances, Shipper shall be billed as described in Section
