                              FSS SERVICE AGREEMENT

THIS AGREEMENT, made and entered into this 16th day of, August, 2004, by and
between:

     Columbia Gas Transmission Corporation
     ("Transporter")
     AND
     PG Energy Inc
     ("Shipper")

WITNESSETH: That in consideration of the mutual covenants herein contained, the
parties hereto agree as follows:

Section 1. Service to be Rendered. Transporter shall perform and Shipper shall
receive service in accordance with the provisions of the effective FSS Rate
Schedule and applicable General Terms and Conditions of Transporter's FERC Gas
Tariff, Second Revised Volume No. 1 (Tariff), on file with the Federal Energy
Regulatory Commission (Commission), as the same may be amended or superseded in
accordance with the rules and regulations of the Commission. Transporter shall
store quantities of gas for Shipper up to but not exceeding Shipper's Storage
Contract Quantity as specified in Appendix A, as the same may be amended from
time to time by agreement between Shipper and Transporter, or in accordance with
the rules and regulations of the Commission. Service hereunder shall be provided
subject to the provisions of Part 284. 223 of Subpart G of the Commission's
regulations. Shipper warrants that service hereunder is being provided on behalf
of Shipper.

Section 2. Term. Service under this Agreement shall commence as of April 1,
2005, and shall continue in full force and effect until March 31, 2010.
Pre-granted abandonment shall apply upon termination of this Agreement, subject
to any right of first refusal Shipper may have under the Commission's
regulations and Transporter's Tariff.

Section 3. Rates. Shipper shall pay Transporter the charges and furnish the
Retainage as described in the above-referenced Rate Schedule, unless otherwise
agreed to by the parties in writing and specified as an amendment to this
Service Agreement. Transporter may agree to discount its rate to Shipper below
Transporter's maximum rate, but not less than Transporter's minimum rate. Such
discounted rate may apply to: a) specified quantities (contract demand or
commodity quantities); b) specified quantities above or below a certain level or
all quantities if quantities exceed a certain level; c) quantities during
specified time periods; d) quantities at specified points, locations, or other
defined geographical areas; and e) that a specified discounted rate will apply
in a specified relationship to the quantities actually transported (i.e., that
the reservation charge will be adjusted in a specified relationship to
quantities actually transported). In addition, the discount agreement may
include a provision that if one rate, component which was at or below the
applicable maximum rate at the time the discount agreement was executed
subsequently exceeds the applicable maximum rate due to a change in
Transporter's maximum rate so that such rate component must be adjusted downward
to equal the new applicable maximum rate, then other rate components may be
adjusted upward to achieve the agreed overall rate, so long as none of the
resulting rate components exceed the maximum rate applicable to that rate
component. Such changes to rate components shall be applied prospectively,
commencing with the date a Commission order accepts revised tariff sheets.
However, nothing contained herein shall be construed to alter a refund
obligation under applicable law for any period during which rates which had been
charged under a discount agreement exceeded rates which ultimately are found to
be just and reasonable.
