FSS SERVICE AGREEMENT

THIS AGREEMENT, made and entered into this 31 day of October 2008, by and between:

COLUMBIA GAS TRANSMISSION, LLC
(“Transporter”)
AND
Washington Gas Light Company
(“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No, 1 (Tariff), on file with the Federal Energy Regulatory Commission (Commission), as the same may be amended or superseded in accordance with the rules and regulations of the Commission.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 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 November 1, 2008, and shall continue in full force and effect until March 31, 2022. Pre-granted abandonment shall apply upon termination of this Agreement, subject to any right of first refusal Shipper may have under Commission’s regulations and Transporter’s Tariff.

Section 3. Rates. Shipper shall pay 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 protectively, 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.
