W-1 RATE SCHEDULE

Hub Service - Wheeling Schedule

3. RATES (Cont'd.)

Posted Rate on the date the Shipper's Hub Nomination Form is

received, as verified by telephone approval, and Shipper's W-1

service agreement will be deemed to be so amended.

3.2 If during the term of a W-1 Nomination, Transporter posts a lower

Posted Rate on the Web Site, Shipper's Wheeling Service Agreement

will be deemed amended to reduce the rate to the current Posted

Rate for the term of the Nomination; provided, however, if the

current Posted Rate is subsequently increased during the term of

that Nomination, the W-1 service agreement will be deemed amended

to reflect the increased rate but no more than the then-current

Posted Rate at the commencement of such Nomination.

3.3 Notwithstanding Paragraphs 3.1 and 3.2, on any day that a Shipper

both tenders and receives gas at the corresponding Hub Points, to

the extent that the quantity tendered and received are equal, the

entire charge shall be a commodity only charge at the current

Posted Rate Schedule W-1 Fly-By Rate per Dth as posted on the Web

Site (ranging between the maximum and minimum of such rate set

forth on the currently effective Sheet No. 9 of this tariff)

times the quantity of gas tendered. In addition, to the extent

that the quantities of gas tendered and received are not equal,

the current Posted Rate Schedule W-1 Fly-By rate shall apply to

the net difference. If Shipper informs Transporter that Shipper

is transferring title to the gas to another party at the Hub

Point at which Transporter is to deliver the gas to Shipper,

Transporter shall deliver that gas at that Hub Point for the

account of Shipper's transferee.

3.4 Except as provided in this section, Transporter will retain the

percent of receipts set forth on Sheet No. 9 as "Fuel and Company

Use retention" and the percent of receipts set forth on Sheet No.

9 as "Transportation LAUF retention". Transporter may from time

to time determine point pairs on its system where the Fuel and

Company Use retention will not be applied to a particular

transaction ("Zero Fuel Point Pair Transactions"). Zero Fuel

Point Pair Transactions will be determined by a review of

projected system flows and the indication that on an aggregate

basis no incremental Fuel or Company Use will be required to

facilitate those transactions. Transporter will post on its Web

Site point pairs where the Fuel and Company Use retention shall

be zero, the
