GENERAL TERMS AND CONDITIONS (Cont'd)

(e) Transporter shall issue OFOs by posting on its Electronic Bulletin Board and by Electronic

Notice Delivery to Shipper's representative. Shippers shall monitor Transporter's Electronic Bulletin Board

for any OFO applicable to Shipper's service and shall be solely responsible for compliance with each OFO.

Electronic Notice Delivery shall be according to the following provisions:

(1) Transporter should provide affected parties with notification of intraday bumps, OFOs

and other critical notices through the affected party's choice of Electronic Notice Delivery

mechanism(s).

(2) Unless the affected party and Transporter have agreed to exclusive notification via

EDI/EDM, the affected party should provide Transporter with at least one Internet E-mail address to be

used for Electronic Notice Delivery of intraday bumps, OFOs and other critical notices. The obligation

of Transporter to provide notification is waived until the above requirement has been met.

(3) Transporter should support the concurrent sending of electronic notification of

intraday bumps, OFOs and other critical notices to two Internet E-mail addresses for each affected

party.

(f) Operational Remedies. Transporter may implement any or all of the following operational

remedies, in any order that Transporter deems necessary, when addressing operational constraints on

Transporter's pipeline system: (1) Transporter may restrict non-firm delivery capacity to Transporter's

affected Market Areas by posting a reduced level (down to zero) of non-firm delivery capacity into those

affected Market Areas; (2) Transporter may allocate internal constraint points in accordance with the

provisions of Transporter's FERC Gas Tariff; (3) Transporter may require individual Shippers to utilize

primary delivery points; (4) Transporter may require individual Shippers to utilize primary receipt points;

(5) Transporter may impose hourly flow rates and limitations in accordance with the provisions of

Transporter's FERC Gas Tariff; and (6) Transporter may limit service to a specific MLI or Aggregate Area.

In addition, as provided in Section 17.1(c) above, Transporter shall provide as much advance warning as

possible of the conditions that may create an OFO and of the anticipated duration of such an OFO. However,

nothing in this Section 17.1(f) shall preclude Transporter from issuing, at any time, an OFO if Transporter

reasonably determines that such an OFO is necessary to protect the integrity of Transporter's pipeline

system or to meet other operational exigencies as provided for in this Section 17.
