GENERAL TERMS AND CONDITIONS (Continued)

2.5 Limitation. The EBB shall be employed by Shippers and other parties for the uses identified in

this Section and elsewhere in this Tariff. To the extent other provisions of this Tariff prescribe that

certain types of communications should be transmitted by the means other than the EBB, those specific

provisions shall govern.

2.6 Relation to Other Provisions. Communications made in accordance with this Section shall satisfy

the requirements of the Rate Schedules, Service Agreements, and General Terms and Conditions, as

specified in this Tariff, and shall be binding upon the parties to the same extent as if transmitted by

any other means permitted by such Tariff provisions. Nothing in this Section, however, shall operate to

override any requirements elsewhere in this Tariff with respect to the need for any communications, or

the deadlines for such communications. In the event any conflict exists between this Section and any

other provision of this Tariff or of any Service Agreement, the latter provisions shall control.

2.7 Propriety and Confidential Nature of Navigator. Columbia Navigator software and the information

contained in Columbia Navigator is proprietary and confidential. Shipper shall not reproduce, disclose,

or otherwise make available Columbia Navigator software, or any confidential information contained

therein, to any other entity or individual. The Columbia Navigator software is a proprietary product of

Transporter and is protected by Copyright Law. As provided at Section 2.11, the data conveyed through

the EBB is not proprietary or confidential by reason of its transmission through the EBB, and enjoys no

greater confidentiality than if communicated through another medium.

2.8 Access Requirements; Operations. Transporter's EBB will operate 24 hours per day, seven days a

week every week of the year. As noted in Section 2.1 above, access to the EBB shall be available to any

party (i) that has compatible electronic equipment and (ii) that complies with the provisions of this

Tariff and, for electronic contracting purposes, with this Section and Section 5.7 of the General Terms

and Conditions.

(a) Equipment. EBB users must have computer equipment, software and Internet service meeting

the minimum standards established by the Gas Industry Standards Board and incorporated elsewhere in this

Tariff. Transporter will operate a toll free telephone helpline answered 24 hours a day, to provide

technical support.

(b) Access Procedure. Any party desiring to use Transporter's EBB may arrange to do so by

contacting Transporter's Navigator Help Desk, making the request, and providing the name, address, and

telephone number of the company and the designated contact person, and other information as may be

required.
