GENERAL TERMS AND CONDITIONS (Cont'd)

(c) Secondary Capacity at the Internal Constraint Points Under Rate Schedule OPT During Periods of

Interruption. For secondary capacity at internal constraint points under the OPT Rate Schedule, Transporter

shall allocate capacity in the following manner. Any interruptions or other allocation reductions to Shipper's

secondary deliveries through internal constraint points under the OPT Rate Schedule shall not reduce Shipper's

allowable days of interruption under that Rate Schedule.

(1) Requests to obtain capacity to secondary delivery points will be evaluated based on

the availability of capacity. Transporter shall post on its Internet EBB those secondary delivery

points by Market Area that Shipper(s) with a particular primary delivery point can access on a priority

basis. Transporter shall, using Transporter's reasonable judgment, have the right to revise the list

from time to time as necessary to protect Transporter's system integrity and primary firm obligations.

Transporter will give as much advance notice of changes in the list as is practicable. Whenever

possible, Transporter shall announce changes in the list at least twenty-four hours prior to the start

of the Gas Day. At the time an announcement of a change(s) is made, Transporter shall post a brief

explanation of the reasons supporting the change(s). This priority, and the priorities in subparagraphs

(2) through (4) below, shall apply where Shipper's aggregate deliveries at primary and secondary

delivery points do not exceed Shipper's Transportation Demand. If a secondary delivery point by Market

Area is not listed, Shippers will be subject to the process for allocating secondary firm and

interruptible ("Non-Firm") capacity described in this Section 7.3(c)(5) below.

(2) Shippers shall be allowed access on a priority basis to secondary delivery points

located within the same market area as their primary delivery points and will not be subject to the

Non-Firm Capacity allocation process described in Section 7.3(c)(5) below. This priority access shall

not be applicable if Transporter, in its reasonable discretion, determines that it must restrict

Shippers to their primary delivery points in order to protect system integrity or Transporter's ability

to meet its primary firm service obligations.

(3) Shippers shall be allowed access on a priority basis to secondary delivery points

where both the receipt and delivery points are located within the same Market Area and shall not be

subject to the Non-Firm Capacity allocation process described in Section 7.3(c)(5) below. This priority

access shall not be applicable if Transporter, in its reasonable discretion, determines that it must

restrict Shippers to their primary delivery points in order to protect system integrity or

Transporter's ability to meet its primary firm service obligations.
