GENERAL TERMS AND CONDITIONS

(Continued)

10. IMBALANCE MANAGEMENT (Continued)

10.4 Determination of Deliveries. At each Point of Receipt or Delivery,

quantities shall be based upon an allocation procedure. Quantities

shall mean quantities Nominated by Shipper and scheduled and

confirmed by Transporter pursuant to Section 6.

(a) At each Point of Receipt and Point of Delivery, Transporter

shall reach agreement with the Interconnecting Party as to

the Predetermined Allocation Agreement (PDA) to be used.

(i) PDAs shall be established using the allocation

methodologies and criteria set forth in the GISB

Standards.

(ii) PDAs for each Gas Day shall be agreed to prior to Gas

flow. To the extent possible, changes to PDAs during a

calendar Month shall be minimized or avoided.

(iii) Transporter shall post via Electronic Transmission the

PDA methodology to be used at each Point of Receipt

and Point of Delivery.

(iv) In the event that less than Confirmed Nominations are

to be allocated, Transporter shall use the ranks

provided in the affected Nominations to determine

Shipper priorities to the extent that use of such rank

is not in conflict with other provisions of this

Tariff.

(v) Transporter may enter into Operational Balancing

Agreements (OBA) at Points of Receipt and Delivery

with the Interconnecting Party. An OBA is a contract

between Transporter and an interconnected operator

which specifies the procedures to manage operating

variances at an interconnect. (GISB Definition 2.2.1)

Such OBAs provide for the allocation of Confirmed

Nominations to the Shippers' accounts with any

operational variances allocated to the OBA. The form

of agreement used by Transporter follows the format of

the Model OBA developed by GISB. Locations covered by

an effective OBA do not require an additional PDA.

(vi) Transporter shall not be liable for any damages which

may directly or indirectly result from Transporter's

implementing the allocation procedures set forth in

this Section, so long as Transporter complies with the

provisions of this Section 10.4 of these General Terms

and Conditions.
