3. PEAKING SERVICE PROVIDED

(a) In accordance with the further provisions of this Rate Schedule, Operator shall (i)

store as LNG, quantities of Natural Gas received for liquefaction or LNG received by

Operator from or on behalf of Buyer during the Injection Season and designated by

Buyer as peaking service quantities, up to the Maximum Contract Peaking Quantity

("MCPQ") as set forth in Buyer's Service Agreement, plus Retainage on injection, and

(ii) deliver to Buyer during the Withdrawal Season equivalent quantities of

regasified LNG less Retainage on withdrawal up to the MCPQ at a daily rate up to one

hundred fifteen percent (115%) of Buyer's MDPQ. Buyer's MDPQ under Rate Schedule

FPS-1 (10-Day Firm Peaking Service) shall equal one-tenth (1/10) of its MCPQ.

Buyer's MDPQ under Rate Schedule FPS-2 (5-Day Firm Peaking Service) shall equal one-

fifth (1/5) of its MCPQ. Buyer's MDPQ under Rate Schedule FPS-3 (3-Day Firm Peaking

Service) shall equal one-third (1/3) of its MCPQ.

(b) Operator's maximum obligation to provide peaking service to all Buyers under all

peaking service Rate Schedules shall be limited to an aggregate MCPQ of 1.29 MMDth

and an aggregate injection quantity of 15,000 Dth per day. Any individual Buyer's

annual injection quantity shall not exceed their MCPQ adjusted for Retainage.

quantities of Natural Gas tendered for liquefaction and/or storage are assumed to

have a minimum heating value of 1,030 Btu's per cubic foot. If Natural Gas or LNG

tendered by or for Buyer has an actual average heating value of less than 1,030 Btu's

per cubic foot, Buyer's MCPQ and MDPQ shall be proportionately adjusted downward.

(d) Buyer, in addition to the firm peaking service received under this Rate Schedule, may

make a one-time election during the term of Buyer's Service Agreement with Operator

to receive transportation service under Operator's Rate Schedule FTS ("Elected FTS

Service"). The Maximum Firm Transportation Quantity ("MFTQ") for such Elected FTS

Service shall not exceed Buyer's MDPQ and the term for such Elected FTS Service shall

not extend beyond the term of Buyer's Service Agreement under this Rate Schedule.

Buyer may nominate quantities of Natural Gas for receipt and delivery along the Cove

Point Pipeline under the Elected FTS Service pursuant to the scheduling provisions of

Rate Schedule FTS; provided, however, that the total daily combined quantities

flowing under this Rate Schedule (exclusive of Authorized Excess Withdrawal

Quantities) and the Elected FTS Service shall not exceed Buyer's MDPQ. The

Reservation Charge to be paid by Buyer each month under the Elected FTS Service shall

be credited against Buyer's monthly charge to be paid pursuant to Buyer's Service

Agreement with Operator under this Rate Schedule. The Elected FTS Service shall have

the same priority for capacity allocations and interruptions as firm transportation

service provided by Operator under Rate Schedule FTS.
