GENERAL TERMS AND CONDITIONS

____________________________

(continued)

3.1 General Nomination Guidelines (continued)

d) In order to maintain efficient operation and to allow for optimum system utilization,

Shipper shall notify Transporter of any changes of daily deliveries to Transporter or daily

receipts from Transporter which deviate from scheduled nominations. Transporter shall

notify Shipper of any changes of daily receipts from Shipper or of any daily deliveries to

Shipper. The notification required by the preceding two sentences shall be made by

telephone or other instant communication immediately upon knowledge thereof.

e) In an effort to expedite the confirmation of nominations with upstream and downstream

interconnects and to facilitate the movement of gas across the pipeline grid, Transporter

shall permit Shipper to aggregate nominations at all points of interconnect under multiple

transportation contracts with the use of a Transporter defined account number. Such

account number will be used by Transporter in the nomination confirmation process with

interconnecting parties.

f) Shipper shall have the ability to make nominations with roll over options and shall have

the ability to nominate for multiple months or years, provided the nomination begin and end

dates are within the term of the Shipper's Service Agreement. Any Shipper submitting

nominations, however, for periods beyond the current month shall be required to submit

revised nominations for the upcoming business month after Transporter's Use percentages for

said month are established. Transporter will post such percentages on its Web Site by the

fifteenth (15th) day of the month preceding business.

g) Transporter has established a pooling point on its system at the Emerson point of

interconnection. For administrative purposes, this pooling point shall be considered a

logical point located immediately downstream of the physical interconnect. Shippers will

be allowed to aggregate gas at the Emerson pooling point from multiple physical or logical

points, and/or dis-aggregate gas from the Emerson pooling point to multiple physical or

logical points. Shippers may make deliveries to the Emerson pooling point from any receipt

point, or make deliveries to any point on the system from the Emerson pooling point. The

priority for the Emerson pooling point shall be the same as the priority for the Emerson

physical point for each Service Agreement.

3.2 Nomination Timeline

a) Shippers, including Title Transfer Tracking Service Providers (TTTSPs), will have five(5)

cycles during which nominations can be submitted: the Timely nomination cycle, the Evening

nomination cycle, the Intra-Day 1 nomination cycle, the Intra-Day 2 nomination cycle, and

the Last Intra-Day nomination cycle. The nominations submitted during the Evening, Intra-

Day 1, Intra-Day 2, and Last Intra-Day nomination cycles shall be known as intra-day

nominations.
