Rate Schedule FT-2

Firm Transportation Service

(Continued)

following the 3-Month Period (the "Impacted Month"). In such event,

HIOS shall notify Shipper on the invoice submitted for the most recent

production month of the 3-Month Period that the average daily throughput

has dropped below 80% of the MDQ for the 3-Month Period and advise

Shipper of the pending Reservation and Commodity Charges so that Shipper

may have an opportunity to release its firm capacity on a temporary

basis pursuant to Section 17 of the General Terms and Conditions during

the Impacted Month. The billing for the Impacted Month will be the sum

of (i) the Long Haul or Short Haul Reservation Charge, as applicable, as

set forth on the currently effective Sheet 10 multiplied by 100% of the

specified MDQ for the Impacted Month; and (ii) the applicable Commodity

Charges set forth on the currently effective Sheet 10 multiplied by the

sum of the quantities of gas (in Dth) received for Shipper's account at

the Point(s) of Receipt each day of the Impacted Month.

Notwithstanding the above, calculation of the average daily throughput

for any 3-Month Period will be adjusted to reflect any reduction in

throughput as a result of HIOS being unable to confirm Shipper's

nominations due to an incident of Force Majeure claimed by HIOS under

Article 13 of the General Terms and Conditions or any limitations

hereunder; and provided, further, with respect to committed reserves

connected after February 16, 1999, services under this Rate Schedule

will be billed for the first six consecutive calendar months, beginning

with and including the month in which deliveries are initiated, at the

Volumetric Charge, regardless of Shipper's ability to meet the 80%

average daily throughput level.
