2.3.5 Service under this Rate Schedule will be provided by

first utilizing Shipper's unused Rate Schedule FS-1

MSDQ and then by utilizing the designated additional

gas supplies described above.

2.3.6 Within the limitations described in Subsections 2.3.1

through 2.3.5 above, the actual level of service

available at any delivery point under this Subsection

2.3 on any given day shall be the lesser of Shipper's

unutilized Rate Schedule FS-1 MSDQ, as adjusted

pursuant to the CAP, designated to serve the particular

delivery point plus the amount of additional verified

gas supply which is received onto Transporter's system

pursuant to the direction of Transporter, and

designated to the particular delivery point, or the

difference between nominated and scheduled firm

deliveries to the primary delivery point under Rate

Schedule FT-1 and Shipper's Rate Schedule FT-1 MDDQ, as

adjusted pursuant to the CAP, for the particular

delivery point.

2.4 For no-notice service below the daily nominated and

scheduled quantity of firm transportation service.

2.4.1 The actual level of service available at any delivery

point under this Rate Schedule on any given day shall

be the lesser of Shipper's unutilized Rate Schedule FS-

1 MSIQ, as specified in Exhibit A to the Service

Agreement and as adjusted pursuant to the CAP, or the

unutilized MSCQ, as adjusted to reflect the weighted

average of the actual Btu content of gas held in

storage for such Shipper, or the difference between

Shipper's specific daily nominated and scheduled

quantity of firm transportation service provided under

Rate Schedule FT-1 and the Rate Schedule FT-1 service

actually taken by the Shipper. In the event service

hereunder occurs during the November 1 - March 31

withdrawal season, injections to storage as a result of

Rate Schedule FTN-1 service shall be allowed on a

reasonable-efforts basis. Such reasonable efforts

injections shall have a higher priority than all

interruptible storage gas for scheduling and

interruption purposes.
