maintained on a Master List of Interconnections (MLI) posted by Transporter on its Electronic Bulletin Board

(EBB). The interconnection points on the MLI shall be incorporated by reference in Shipper's ITS Service

(e) During any Month, Shipper shall not be permitted to increase its existing flowing quantities

under this Rate Schedule, regardless of the Transportation Quantity set forth in Shippers's ITS Service

Agreement, if such increase would cause a reduction of existing quantities flowing on Transporter's system

quantities being transported, if requested by Shipper and approved by Transporter, shall not reduce the level

of Shipper's existing quantities flowing on Transporter's system for purposes of this paragraph.

(f) Service rights under an ITS Service Agreement may not be released and assigned.

Maximum ITS Rate shall be deemed to be at the Maximum ITS Rate. Bids submitted for higher than a previously

agreed to discounted rate shall be deemed to supersede such discounted rate. Transporter may reject any bids:

(i) for an amount lower than the Minimum Bid Rate; or (ii) from bidders that do not currently have an ITS

Service Agreement with Transporter.
