6. ENHANCED SERVICE FEATURES

6.1 Elimination of Storage Ratchets. Shippers may elect to have the MDIQ and the

MDWQ equal to the Base MDIQ and Base MDWQ, respectively. The applicable

maximum reservation rate for Rate Schedule FSS service pursuant to such an

election shall be stated on Sheet No. 10 or 10A, and denoted as Rate Schedule

FSS service without Storage Ratchets.

6.2 Flexible Entitlements. Subject to the determination in Section 1(a), above,

Rate Schedule FSS Shippers may elect flexible injections and withdrawals from

storage ("Flexible Entitlements") to permit injections and withdrawals on any

Day of the Storage Contract Year, provided, however, that in no event shall

any Shipper be entitled to firm withdrawals in excess of the then current MSQ

Gas balance or to inject amounts above the MSQ. The applicable maximum

reservation rate for Rate Schedule FSS service pursuant to such an election

shall be stated on Sheet No. 10 or 10A, and denoted as Rate Schedule FSS

service with Flexible Entitlements. The Injection Period and Withdrawal

Period under such an election shall be consecutive monthly periods commencing

April 1, provided, however, that if (a) the sum of: (i) the Shipper's MSQ

divided by its Base MDWQ; and (ii) the Shipper's MSQ divided by its Base MDIQ,

exceeds 365, or (b) the Storage Contract Year is less than 365 days, such

Shipper may commence service on a Day other than April 1.

6.3 Cycling of Gas. Shippers electing Flexible Entitlements pursuant to Section

6.2, above, shall during the Injection Period and the Withdrawal Period be

permitted to inject and withdraw ("Cycle"), respectively, quantities of Gas

above the normal single Cycle allowed for other Shippers. The ability to

Cycle under this section does not create any additional firm rights. Rather,

the Shipper's ability to Cycle is both limited as defined below and by the

physical limitations inherent in the Shipper's Base MDIQ, Base MDWQ, MSQ and

Storage Contract Year. Cycling under Flexible Entitlements shall be permitted

up to 1.42 times the MSQ within any Storage Contract Year, provided, however,

that in the case of any Shipper with a Base MDWQ between 1/10 - 1/49 of its

MSQ, the respective Injection Period and Withdrawal Period quantities shall be

equal to the quotient of 365 divided by the sum of: (a) the Shipper's MSQ

divided by its Base MDWQ; and (b) the Shipper's MSQ divided by its Base MDIQ.

The storage of Gas in excess of MSQ, or the injection or the withdrawal of Gas

in excess of the allowed Cycle(s), as the case may be, shall be permitted only

on a best efforts, overrun basis. For the purposes of determining the

applicable limits on injections and withdrawals pursuant to this provision,

quantities allocated as Designated Storage Account activity pursuant to the

provisions of Rate Schedule NNS shall not be included in the calculations of a

Shipper's accumulated injections and withdrawals of Gas.

6.4 In-Field Transfers. A Shipper may elect to fill the MSQ, in whole or in part,

through an in-field transfer of Gas subject to Section 18.12 of the General

Terms and Conditions of this Tariff. Such an election will neither increase

nor diminish the Base MDIQ, Base MDWQ, or MSQ. Except as provided in Section

3.4 above, for gas currently in the storage account, the sum of a) the Gas

nominated, injected and b) the Gas moved into the account through one (1) or

more in-field transfers, may not exceed the MSQ.
