Overrun Gas quantities may be rescinded, and notification that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.
