3. CONDITIONS OF SERVICE (Continued)

3.5 Release of Rate Schedule NNTH Capacity.

(a) Shipper may release its Rate Schedule NNTH capacity for service

under Rate Schedule NNTH. The Acquiring Shipper will retain

hourly service delivery rights, as defined in the Releasing

Shipper's NNTH TSA, at the primary delivery points listed in

the Releasing Shipper's NNTH TSA. The Acquiring Shipper may

nominate to alternate delivery points on a secondary basis

subject to the provisions of Section 2.4(d) of this Rate

Schedule.

(b) An Acquiring Shipper who re-designates a primary delivery point

to another Premium Service Delivery Point will retain hourly

service rights at such point if service to the re-designated

point is Operationally Equivalent to service at the primary

point.

(c) Released Rate Schedule NNTH capacity will become Rate Schedule

FT-1 capacity if the Acquiring Shipper re-designates an

acquired Delivery Point to a non-Premium Service Delivery Point

or a non-Operationally Equivalent Premium Service Delivery

Point; however, the Acquiring Shipper will continue to pay the

maximum applicable Rate Schedule NNTH rates for such service

until the next general rate proceeding.

(d) Shipper may not separately release the no-notice (un-nominated)

portion of its NNTH TSA.

3.6 Flow day diversions, pursuant to Section 6.5 of the GT&C, are

available to Rate Schedule NNTH Shippers.

3.7 From time to time, Transporter may request Shipper, upon mutual

consent, to go out-of-daily balance and/or to take hourly gas

quantities in a manner different from its Hourly Scheduled

Entitlement or different from its Hourly Contract Entitlement. Any

such action will not result in daily unauthorized overrun penalties,

hourly scheduling penalties, or Critical Condition charges pursuant

to this rate schedule. Furthermore, Shipper may offer in writing to

assist Transporter in system loading needs. Transporter will process

such offers in a reasonable and orderly fashion as time permits given

the Critical Conditions. Transporter may accept or reject such offer

in writing using its best operational judgment. If Transporter

accepts such offer, Shipper's actions in helping system loading needs

will not result in daily unauthorized overrun penalties, hourly

scheduling penalties, or Critical Condition charges pursuant to this

rate schedule. However, if Shipper takes any actions without first

obtaining the written agreement of Transporter, Shipper will be

subject to all applicable penalties and charges.
