FORM OF SERVICE AGREEMENT

(continued)

WHEREAS, Transporter desires to establish a logical (administrative) "pooling point" for each of

its pooling areas ("Supply Pooling Point") where gas supplies within such pooling area may be pooled

for administrative purposes.

NOW THEREFORE, in consideration of the covenants and agreements contained herein, Transporter and

Shipper (sometimes hereinafter collectively referred to as the "Parties", or individually as a

"Party") agree as follows:

1. Pooling Points. Transporter has established Supply Pooling Points, which are pooling area

specific, and are posted on Transporter's Internet Website and incorporated herein by reference.

Shipper may nominate to Transporter (in accordance with Paragraph 3 of this Agreement) volumes of gas

from various physical receipt points within a pooling area for pooling at the applicable Supply

Pooling Point for such receipt points within such pooling area by designating such Pooling Point as

the delivery point. It is understood and agreed by the Parties that gas from designated physical

receipt points within a pooling area may only be pooled at the applicable Supply Pooling Point for

such receipt points within the pooling area.

2. Transfer of Title. Shipper may elect to transfer title to gas pooled pursuant to this

Agreement (at the same Supply Pooling Point) to another shipper who is a party to a Pooling Agreement or

a Transportation Service Agreement with Transporter. This will allow transfers from Shipper to another

Shipper to take place at a Supply Pooling Point, and a Supply Pooling Point may be nominated (in
