GENERAL TERMS AND CONDITIONS

(continued)

10. ASSIGNMENT AND CURTAILMENT OF CAPACITY (continued)

10.2 Form. Requests for service shall contain the items of information

listed commencing on Sheet No. 696 of this Tariff and shall be

submitted in the manner provided in the applicable Rate Schedule.

10.3 Requests For Firm Capacity. Complete requests for firm service by

a Shipper offering and willing and able to pay the maximum rate

applicable to such service, in accordance with this Tariff, will

be reviewed on a first-come, first-served basis according to the

date of Transporter's receipt of such requests. Requests for firm

service shall be accepted and capacity assigned if Transporter

determines, following its review and evaluation of a completed

request, that sufficient available and uncommitted capacity exists

to perform the requested services on a firm basis. Transporter

shall make such determinations based on its assessment of overall

system operations and requirements utilizing consistent and

objective engineering and operational criteria. If insufficient

capacity exists to meet all pending requests to enter into or

amend firm Service Agreements, Transporter shall assess the

relative engineering suitability and economic value to Transporter

of the requested services to determine the priority.

Transporter's evaluation of total economic value shall consider

rate, quantity, term, operational impacts and maximization of

overall system utilization. For purposes of the foregoing, a

Shipper offering and willing and able to pay a Negotiated Rate

will be subject to the provisions of Section 12.3 below. If more

than one pending request is determined by Transporter to be of

equal suitability and economic value, Transporter shall conduct a

lottery on a non-discriminatory basis after two (2) Business Days'

notice to the affected parties, who will have the right to attend.

Capacity will be assigned in accordance with the order of draw,

with capacity assigned to the first drawn Shipper up to the

quantity requested by such Shipper. If any firm capacity remains

after such assignment, it shall be assigned to the other

requesting Shippers in accordance with such Shippers' order of

draw. The result of the lottery shall be posted on Transporter's

Internet Web Site within two (2) Business Days of the drawing.

During the term of the Service Agreement, any change Shipper may

make in the terms of the Service Agreement (including utilization

of flexible receipt and/or delivery points as provided in this

Tariff) shall not reduce the economic value
