11. RECEIPT POINT FLEXIBILITY (Continued)

Transporter shall utilize the cost of the facilities as set

forth on "Exhibit C" and the methodologies for calculating

cost of service which underlie its currently effective

transportation rates, as revised from time to time.

Shipper may elect at any time to cease paying the

Facility Cost-of-Service Charge by paying Transporter for

the then remaining net book value of that portion of the

facilities for which Shipper is responsible to pay pursuant

to Section 11(a) hereof, including any related income taxes.

In the event that Shipper ceases operations at the

end-use point or receipt point for which the facilities were

installed, or ceases to be a Rate Schedule TF-1 Shipper

(unless its facility cost reimbursement obligations

hereunder are assumed by a replacement Shipper) before

Shipper reimburses Transporter for the cost of those

facilities in full, Shipper will pay Transporter for the

then remaining net book value of that portion of the

facilities for which Shipper is responsible to pay pursuant

to Section 11(a) hereof, including any related income taxes.

Transporter shall not transfer any ownership interest

agreed to pursuant to Section 11(g) to Shipper prior to

payment in full of the Cost-of-Service Charge.

(d) Shipper may contract either with Transporter or a third party to

install such facilities, provided, however, that Transporter shall

install all taps and related valves or check valves.

Transporter shall operate and maintain all equipment unless

otherwise agreed to in writing by Transporter and Shipper. All

such facilities must include any rights-of-way necessary to access

facilities for inspection and maintenance. Any such facilities

constructed by Shipper or third parties must be in accordance with

Transporter's specifications. Transporter must approve design

drawings and bills of materials, and construction shall be subject

to approval by Transporter's inspectors.
