OPERATIONAL BALANCING AGREEMENT

(continued)

(2) The Parties intend that the quantity of gas in Dth actually delivered and received each

Day at the Interconnection Point will equal the confirmed, scheduled nominations of the

Parties. Each Party will allocate the quantity that is to be delivered and received at

the Interconnection Point among its Shippers pursuant to the confirmed, scheduled

nominations. Any difference between the actual physical flow of gas at the

Interconnection Point each Day and the confirmed, scheduled nominations of receipts and

deliveries for such Day is the "Operational Imbalance," which is the responsibility of

the Parties to eliminate pursuant to this Agreement.

(3) Unless the Parties otherwise mutually agree in writing:

a. Each Party shall adjust the operations of its natural gas facilities as necessary

in order to keep the measured flow of gas at the Interconnection Point as nearly

as possible equal to the confirmed, scheduled nominations, but in any event to

within [tolerance]. The measuring facilities owned and operated by a Party which

measures receipts and deliveries at the Interconnection Point shall be a part of

that Party's natural gas facilities for purposes of this Agreement.

b. Neither Party shall be expected to adjust the operation of its natural gas

facilities below a minimum delivery pressure of _____________ or above the

maximum allowable operating pressures of its natural gas facilities at the

Interconnection Point.

c. The Parties agree to cooperate with each other in the making of the adjustments

required under subparagraph (3)a.

If it becomes apparent to either Party that the daily Operational Imbalance exceeds, or

is projected to exceed, the [tolerance], such Party shall immediately orally notify the

other Party thereof and the Parties shall immediately adjust the operations of their

natural gas facilities pursuant to paragraph 3 in order to keep the confirmed,

scheduled nominations and the Operational Imbalances within the applicable tolerances

set forth above. In the event the Parties cannot, for any reason, adjust operations of

their natural gas facilities as provided in this paragraph 3, the Parties shall adjust

the allocation of gas to shippers at the Interconnection Point in
