GENERAL TERMS AND CONDITIONS (Continued)

10. ALLOCATION OF UNCOMMITTED CAPACITY (Continued)

years. Uncommitted firm capacity will be awarded to successful

potential Shippers based upon the highest net present value per unit of

demand to the lowest net present value per unit of demand. A potential

Shipper paying a negotiated rate will be awarded uncommitted firm

capacity in accordance with Subsection 51.3 of these General Terms and

Conditions. If a bidding Shipper(s) has been determined to be the

successful potential Shipper, the requesting Shipper shall have until

the earlier of twenty-four (24) hours from notification or 9:30 a.m.

(Central Clock Time) on the first business day prior to the requested

commencement date to match or exceed the net present value per unit of

demand of the higher bid. If the requesting Shipper does not elect to

match or exceed the higher bid and should sufficient capacity not exist

to satisfy identical successful requests and/or bids under the

appropriate economic standard, the capacity will be awarded to the

successful potential Shipper(s) based upon the order the requests and

bids were posted, beginning with the first posted request or bid until

all available capacity is awarded. If identical successful bids are

posted simultaneously, Transporter will pro rate such available

uncommitted firm capacity between such successful potential Shippers.

Nothing herein shall require Transporter to accept a request or bid

which provides a discounted rate for acquiring such service. In

addition, all awards of firm capacity must be for continuous service at

a constant quantity for the entire term of the Service Agreement.

Transporter will award capacity for non-continuous service at a constant

quantity for the entire term of the Service Agreement if the capacity is

not available for a portion of the requested term of the Service

Agreement. Transporter will post notification of all successful

request(s) and/or bid(s), along with the successful Shipper's name,

after a Service Agreement has been executed by the Shipper and

Transporter.

10.4.1 Capacity Allocation: Request(s) and/or bid(s) for

receipt and/or delivery point capacity in excess of the maximum

capacity available at such receipt and/or delivery point(s), shall

be reduced by Transporter to the maximum capacity available at

such receipt and/or delivery point(s). Request(s) and/or bid(s)

for mainline capacity in excess of the mainline capacity

determined by Transporter in accordance with the provisions of

Subsection 10.1 of these General Terms and Conditions shall be

reduced by Transporter to the maximum mainline capacity available.

10.4.2 Multiple Requests: If Transporter posts multiple

requests for capacity with overlapping terms and bid periods, such

requests
