FT-S RATE SCHEDULE

Firm Transportation Service - Seasonal

3. RATE (Cont'd.)

(f) With respect to services resulting from the assignment of

capacity associated with Transporter's Rate Schedule X-58

to firm shippers of Transcontinental Gas Pipe Line

Corporation, a surcharge to Transporter's reservation and

commodity charges (set forth on Sheet No. 9 as "X-58

conversion surcharge"), applicable to services that were

converted from Mcf to Dth on the basis of 1.000 Dth per

Mcf.

(g) With respect to the following Service Agreement (and

agreements with replacement shippers taking release of

capacity thereunder), a surcharge to Transporter's

reservation charge, identified on Sheet No. 8 as "FT-S

Winter Service Surcharge":

Husky Energy Marketing, Inc. - Service Agreement #F02098.

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

percent of receipts set forth on Sheet No. 8 as "Fuel and Company

Use retention" and the percent of receipts set forth on Sheet 8

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 quantity eligible for such treatment, and the term

of such eligibility. To the extent that more requests for Zero

Fuel Point Pair Transaction capacity are received than

Transporter has eligible capacity, such capacity will be awarded

pursuant to Section 13.2 of the General Terms and Conditions. If

Transporter later determines that incremental Fuel and Company

Use is required to facilitate a transaction that had previously

been identified as not requiring incremental Fuel and Company

Use, Transporter will post such information to its Web Site and

will require Fuel and Company Use reimbursement on a going

forward basis; provided, however, Transporter will continue to

honor any Zero Fuel Point Pair Transactions with respect to

primary receipt and delivery
