FNG1 — This footnote applies to the following Measuring Point No.: LOSTRI




THE HAMPSHIRE INJECTION MDDO IS ZERO (0) DTH/D FROM NOVEMBER 1 THROUGH MARCH 31. IN NO EVENT SHALL
THE HOURLY WITHDRAWAL QUANTITY EXCEED 105% OF 1/24TH OF THE RATE SCHEDULE X-39 WHICH CONTRACT
DEMAND LEVEL IS BASED ON A CONVERSION FACTOR OF
1.035 DTH PER MCF.



FN02 — This footnote applies to the following Measuring Point Nos: 802675, 802677, and 837337,




THE MAXIMUM DAILY DELIVERY OBLIGATIONS FOR LOUDOUN, DRANESVILLE AND ROCKVILLE SHALL APPLY ON AN
HOURLY BASIS AS FOLLOWS: THE MAXIMUM HOURLY FLOW RATE TRANSPORTER IS OBLIGATED TO PROVIDE TO
WASHINGTON GAS (WG), AT LOUDOUN, DRANESVILLE AND ROCKVILLE WILL BE 5,490, 5,633, AND 20,765
DTH/HOUR RESPECTIVELY, PROVIDED WG MAINTAINS A TOTAL FIRM ENTITLEMENT OF 751,087 DTH/DAY AND THE
CURRENT MAXIMUM DAILY DELIVERY OBLIGATIONS OF 131,758 DTH/DAY AT LOUDOUN, 132,542 DTH/DAY AT
DRANESVILLE, AND 488,585 DTH/DAY AT ROCKVILLE AND 50,000 DTHS OF HAMPSHIRE (X-39) VOLUMES ARE
NOMINATED, CONFIRMED AND SCHEDULED (NCS) ON ANY GAS DAY.



THE MAXIMUM HOURLY FLOW RATE OBLIGATION OF 20,765 DTH/HOUR AT ROCKVILLE IS CONTINGENT UPON 50,000
DTHS BEING NOMINATED, CONFIRMED, AND SCHEDULED FROM HAMPSHIRE (X-39) ON ANY GAS DAY. THE MAXIMUM
HOURLY FLOW RATE OBLIGATION OF 20,765 DTH/HOUR WILL BE PROPORTIONATELY REDUCED WHEN VOLUMES LESS
THAN 50,000 DTHS ARE NOMINATED, CONFIRMED AND SCHEDULED FROM HAMPSHIRE (X-39). FOR EXAMPLE, THE
MAXIMUM HOURLY FLOW RATE OBLIGATION AT ROCKVILLE WOULD BE 20,358 DTH/HOUR AND 20,561 DTH/HOUR WHEN
THE NOMINATED, CONFIRMED AND SCHEDULED QUANTITIES FROM HAMPSHIRE (X-39) ARE ZERO (0) AND 25,000
DTHS ON ANY GAS DAY.



IF THERE IS A REDUCTION IN THE TOTAL FIRM ENTITLEMENT OR THE CURRENT MAXIMUM DAILY DELIVERY
OBLIGATIONS OF WG AT LOUDOUN, DRANESVILLE AND/OR ROCKVILLE, THE MAXIMUM HOURLY FLOW RATE AT THESE
POINTS WILL BE DETERMINED AS FOLLOWS: LOUDOUN 1/24TH OF REVISED MDDO;
DRANESVILLE 102% OF 1/24TH OF
THE REVISED MDDO; AND ROCKVILLE 1/24TH OF THE REVISED MDDO PLUS THE HOURLY FLOW RATE ASSOCIATED
WITH THE HAMPSHIRE (X-39) VOLUMES REFERENCED ABOVE. 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
	 
	•	 	ANY SST QUANTITIES REDUCED AS A RESULT OF SEASONAL ADJUSTMENTS.

SST 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 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 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 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.
