5.3 Overrun Gas.

(a) Authorized Overrun: Shipper may request, in accordance with

Section 5 of the General Terms and Conditions, or

Transporter may consent, to deliver quantities of Gas for

Shipper's account for any given time period during the

Service Month in excess of the Contract Limitations.

Transporter's consent to authorized Overrun Gas quantities

may be rescinded, and notification that Overrun Gas

quantities will not be scheduled or will be reduced may be

communicated via Transporter's Internet Web Site; provided,

however, that Transporter shall also make reasonable efforts

to contact those Shippers who had nominated and scheduled

authorized overrun quantities for the applicable period

prior to the posting, via telephone, facsimile or

electronically via the Internet, which may occur during the

scheduling process. If, in order to schedule service under

Rate Schedule HFT, a Shipper receiving authorized overrun

quantities must be bumped during the Day other than pursuant

to the timelines provided in Section 5.5(a)(i) of the GT&C,

Transporter will provide notice as soon as practicable (but

at least sixty (60) minutes prior to bumping) electronically

via the Internet or by telephone to such Shipper.

Transporter shall provide telephonic notice by placing a

call to a number which must be supplied by Shipper,

available twenty-four (24) hours per Day, and equipped with

voice mail or other electronic messaging. Transporter may

render the requested service on an interruptible basis,

subject to the terms of Rate Schedule IT, if Transporter

determines that it can do so without adverse effect on its

operations or its ability to meet all its other obligations,

and such quantities shall be considered authorized Overrun

Gas under this Rate Schedule.

(b) Unauthorized Overrun: All quantities transported for

Shipper's account which exceed the amount Shipper is

authorized to transport at any given time, other than

Overrun Gas authorized as described in Section 5.3(a) above,

shall be considered unauthorized.
