Firm Redelivery Transportation (Continued)




6.1 Annual Contract Quantity: The Annual Contract Quantity is a

quantity in Dth set forth in each executed Service Agreement and, as

adjusted for any capacity releases pursuant to Section 22 of the General

Terms and Conditions, represents the quantity of transportation service

which each Shipper may receive during each twelve-month period ending

September 30 without being subject to the Annual Overrun Charges

described in Section 3.5 herein. A Shipper's Annual Contract Quantity

initially may not be less than such Shipper's Storage Capacity specified

in the related firm storage Service Agreement initiated pursuant to any

storage service rate schedule contained in this Tariff (or in the tariff

of any third party providing storage services to Shipper) or such

Shipper's related entitlement to firm storage capacity as an owner in

the storage facility. Subsequent increases in such Shipper's Storage

Capacity or ownership rights to firm storage capacity will not require

corresponding changes to the related Annual Contract Quantity.


The Annual Contract Quantity may be increased at any time, subject

to availability of capacity, but may only be decreased due to permanent

releases of capacity pursuant to Section 22.5 of the General Terms and

Conditions or in connection with the filing of a general Section 4 rate

case by Transporter. Transporter shall provide Shippers with an

opportunity to make such an election prior to filing such rate



6.2 Monthly Billing Quantity: The Monthly Billing Quantity is a

quantity in Dth set forth in each executed Service Agreement and

represents the quantity used by Transporter to bill the Reservation

Charges specified in Section 3.1 to each Shipper. The Monthly Billing

Quantity for each Service Agreement shall be derived as follows: (i)

Shipper's Annual Contract Quantity is divided by Contract Demand,

resulting in Equivalent Days of Service, (ii) Equivalent Days of Service

is divided by 365 days to derive the Days of Service Factor, and (iii)

the Days of Service Factor is multiplied by Shipper's Contract Demand to

derive the Monthly Billing Quantity.
