GENERAL TERMS AND CONDITIONS

----------------------------

(c) (1) If nominations under interruptible Agreements on

any day exceed Trailblazer's available capacity on that day to provide

such services, Trailblazer shall, to the extent possible given the

priorities imposed by upstream or downstream transporters, allocate

available capacity as set out in this subsection (b) among Shippers which

have executed interruptible Agreements.

(i) Trailblazer shall schedule interruptible

services (including authorized overrun) based on the rate to be paid,

from highest to lowest daily rate, with service for which the highest

daily rate being paid is scheduled first. Any Shipper paying the maximum

rate applicable to its service (or revenue equal to or greater than the

applicable maximum rate pursuant to a Negotiated Rate or Negotiated Rate

Formula) shall be afforded highest priority even if a Shipper which has

agreed to a Negotiated Rate or Negotiated Rate Formula is paying a higher

unit rate.

(ii) In the event there is insufficient

capacity to schedule all interruptible services for which the same rate

is to be paid, Trailblazer shall allocate the available capacity pro rata

based on the confirmed nomination volume.

(2) Notwithstanding Section 6.5(b)(1) hereof,

Trailblazer reserves the right, after a one (1) day notice, to interrupt

service to any interruptible Shipper paying a discount rate to enable

Trailblazer to provide service to another Shipper if such service would

result in a higher unit rate; provided, however, that Trailblazer will

not interrupt service to a Shipper paying the applicable maximum rate (or

revenue equal to or greater than the applicable maximum rate pursuant to

a Negotiated Rate or Negotiated Rate Formula) even if a Shipper which has

agreed to a Negotiated Rate or a rate under a Negotiated Rate Formula

would pay a higher unit rate. Within such one (1) day period, Shipper

shall be allowed to increase its rate by any amount up to the applicable

maximum rate specified in this Tariff. A Shipper agreeing to increase its

rate hereunder shall be entitled to any higher priority associated with

such higher rate; provided, however, that any Shipper paying the maximum

rate applicable to its service (or revenue equal to or greater than the

applicable maximum rate pursuant to a Negotiated Rate or Negotiated Rate

Formula) shall be afforded highest priority even if a Shipper which has

agreed to a Negotiated Rate or Negotiated Rate Formula is paying a higher

unit rate. Among Shippers paying less than the applicable maximum rate,

priority shall be determined based on rate level. Among Shippers agreeing

to pay the same rate as of the termination of the one (1) day notice

period, the priorities set out in Section 6.5(b)(1) shall apply. No

Shipper may obtain a higher priority during any period of interruption to

which a notice relates by agreeing to an increased rate after the end of

the one (1) day notification period.
