RATE SCHEDULE FT-D

FIRM TRANSPORTATION SERVICE (Conditional)

(continued)

2. APPLICABILITY AND CHARACTER OF SERVICE (continued)

2.2 Company shall provide southbound service under Rate Schedule FT-D transportation

by means of a turbine compressor engine located at Company's Paris, Illinois

compressor station (together with any replacement engine, the "Paris Turbine").

The Paris Turbine is subject to air emissions restrictions that prevent Company

from operating it more than 6,090 hours during any rolling twelve (12) month

period. FT-D Service is subject to curtailment (an "FT-D Curtailment") when such

interruption is due to a shutdown of the Paris Turbine to avoid exceeding this

operating limit. Any other interruption or curtailment (including those arising

from shutdown of the Paris Turbine for other reasons) of firm service due to

force majeure or otherwise would apply to all affected firm service equally and

would not be an FT-D Curtailment, as defined above.

2.3 Service shall be allocated and scheduled pursuant to Subsections 3.7, 3.8 and

Section 15 of the General Terms and Conditions of Company's FERC Gas Tariff.

However, service may be curtailed pursuant to an FT-D Curtailment or for any of

the reasons set out in Section 10 of the General Terms and Conditions of

Company's FERC Gas Tariff or whenever necessary to maintain gas quality or the

integrity of Company's system.

2.4 To assist Shippers in tracking the potential for FT-D Curtailment, the Company

shall post, on the 15th day of every month, a report on the actual turbine

compressor runtime hours of the preceding eleven month(s).

2.5 Company shall not be required to install, operate or maintain any additional

facilities in order to provide new transportation service under this Rate

Schedule.
