GENERAL TERMS AND CONDITIONS

(continued)

20. OPERATIONAL CONTROLS (continued)

(c) Communications under this section, including of Operational

Alerts and Operational Flow Orders, shall be posted on

Transporter's Internet Web Site. Further, Transporter shall

make reasonable efforts to notify each affected Shipper's

contact party, designated pursuant to the provisions of

Section 5.9 of these General Terms and Conditions, of the

issuance of an Operational Flow Order or Operational Alert.

Such communications will, as applicable, specify actions

that, in Transporter's opinion, could forestall or alleviate

the operational situation, including, but not limited to,

receipts or deliveries at specific points or in specific

areas or segments of Transporter's system.

(d) To the extent practicable given operating circumstances and

exigencies, Operational Flow Orders shall require action

within any Shipper class proportionate to appropriate and

relevant parameters, such as applicable Service Agreement

quantities or a current or recent flow in Gas quantities.

(e) From time to time, Transporter, in order to support Tariff

services to Shippers, control and maintain efficient system

operations and otherwise implement the provisions of this

Tariff, may purchase and/or sell quantities of Gas to

maintain system operational Gas levels within optimum levels

and to provide, if requested by Shipper and agreed to by

Transporter, quantities required to be retained by

Transporter under this Tariff. Such activities shall be

conducted by Transporter's operating personnel, separate and

apart from any unbundled merchant activities and personnel,

and shall in no way constitute marketing activities so as to

subject Transporter, or any operating unit thereof, to

Commission requirements, as in effect from time to time,

applicable to pipeline marketing affiliates or pipeline

unbundled merchant activities.
