transportation service provided under Rate Schedule FT-1 up to

the Maximum Daily Delivery Quantity (MDDQ) specified for that

delivery point in Exhibit A to the Service Agreement under this

Rate Schedule FTN-1, as adjusted pursuant to the Capacity

Adjustment Provision (CAP) (described in Subsection 1.47 of the

General Terms and Conditions of this Tariff). Provided,

however, that Transporter shall not be required to execute a

FS-1 MSDQ in accordance with Subsection 1.4 of Rate Schedule

FS-1.
