2.8 Any quantity change to deliveries requested at a Market Point

shall be designated as a delivery to an Alternate Delivery Point,

and at a Balancing Point(s) shall be designated as a receipt to an

Alternate Receipt Point, for purposes of Priority of Service and

Curtailment under section 7 of the GT&C and shall comply with all

NAESB standards.

2.9 In the event more than one Balancing Provider is providing

balancing service at the same Market Point, the point operator of

that Market Point shall provide Transporter with a predetermined

allocation.

2.10 Where Balancing Provider fails, after confirmation by Transporter

in section 2.7(b), to provide for the receipt or delivery of

sufficient quantities of Gas to effectuate a requested balancing

service at a Market Point, Balancing Provider shall be deemed

responsible for any resultant charges under the GT&C, including

under GT&C section 16, should Transporter issue an operational

flow order. To the extent Balancing Provider causes an imbalance

quantity in excess of the maximum imbalance coverage per Day set

forth in the MBA Agreement, Transporter may terminate the MBA

Agreement without further notice. Such termination will not

relieve Balancing Provider of its liabilities under this Rate

Schedule, or such other lawful remedies as Transporter may pursue.
