SST SERVICE AGREEMENT

THIS AGREEMENT, made and entered into this 8th day of April    , 2004, by and between:

Columbia Gas Transmission Corporation

(“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 SST 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No. 1 (Tariff), on file with the Federal Energy Regulatory Commission (Commission), as the same may be amended or superseded in accordance with the rules and regulations of the Commission. The maximum obligation of Transporter to deliver gas hereunder to or for Shipper, the designation of the points of delivery at which Transporter shall deliver or cause gas to be delivered to or for Shipper, and the points of receipt at which Shipper shall deliver or cause gas to be delivered, are 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 June 1, 2004, and shall continue in full force and effect until October 31, 2005 and from Year -to- Year thereafter unless terminated by either party upon 6 Months’ written notice to the other prior to the end of the initial term granted or any anniversary date thereafter. 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 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.

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.

THE HOURLY FLOW RATE INCREASE ASSOCIATED WITH ANY INCREASES TO THE MDDO’S AT LOUDOUN, DRANESVILLE AND/OR ROCKVILLE WILL BE NEGOTIATED BUT THE INCREASE WILL NOT BE BELOW 1/24TH OF THE MDDO OR TFE ADDITION.
	ANY DIFFERENCE BETWEEN WG’S ACTUAL HOURLY USAGE AT ROCKVILLE AND WG’S CONTRACTUAL HOURLY FLOW COMMITMENT AT ROCKVILLE WILL INCREASE WG’S HOURLY FLOW RIGHTS AT EITHER DRANESVILLE OR LOUDOUN, SUBJECT TO FACILITY LIMITATIONS AND PRIMARY FIRM OBLIGATIONS AT THOSE POINTS.
	THESE HOURLY FLOWRATE OBLIGATIONS WILL BE PROPORTIONATELY REDUCED BY 100% OF 1/24TH OF:

• QUANTITIES NOMINATED, CONFIRMED, AND SCHEDULED UNDER WG’S FTS SERVICE AGREEMENTS BELOW THE MAXIMUM CONTRACT QUANTITY ON ANY GAS DAY.

• FTS OR SST QUANTITIES THAT ARE NOMINATED, CONFIRMED, AND SCHEDULED TO A SECONDARY DELIVERY POINT, AND
