GENERAL TERMS AND CONDITIONS FOR SERVICES - continued

25. DETERMINATION OF DELIVERIES

25.1 For purposes of billing, the order of nominated services through a

particular delivery point, unless otherwise determined, will be:

a. Nominated FT;

b. Nominated IT;

c. Authorized contract overrun deliveries;

d. Imbalance gas;

e. Unauthorized contract overrun deliveries.

25.2 At any receipt or delivery point, Transporter will allocate

flows to Shippers according to the following methodology:

a. Gas will be allocated first to firm transportation through

the point, up to the daily nomination. If insufficient

gas is available to satisfy firm nominations, the

available gas will be allocated pro rata based on firm

nominations;

b. Any remaining volumes will be allocated pro rata to

interruptible transportation based on the approved

nominations.

25.3 PREDETERMINED ALLOCATION AGREEMENTS. Transporter will enter into

mutually acceptable predetermined allocation agreements with

upstream or downstream parties to accommodate allocation

methodologies different than outlined in Section 25.2. The

allocation methodology types which two parties may agree upon are

ranked, pro rata, percentage, swing and operator provided

value. If the two parties cannot agree upon an allocation

methodology, pro rata based on confirmed nominations

shall be used as the default method. The party

responsible for custody transfer (the party performing the

measurement function) shall provide the allocation. Two welded

parties shall agree on who submits a predetermined allocation

methodology and who allocates at the point before gas flows.

There is no need to submit predetermined allocation if a

transportation service provider has an operational balancing

agreement in effect for a point. Only one predetermined

allocation methodology shall be applied per allocation period.

The upstream or downstream party providing the point confirmation

shall submit the predetermined allocation to the allocating party

after or during confirmation and before start of gas day. The

allocating party shall send
