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 Maximum Contract Quantity.

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may be rescinded, and notification that Overrun Gas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 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 hereunder 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 for purposes of this

Rate Schedule.
