storage balance, then such gas will be subject to cash-out provisions at 150% of

the highest weekly average for the month pursuant to Section 14 of the General

Terms and Conditions of this tariff.

4. Storage Overrun Service

4.1 Customer may request Pipeline to inject for storage quantities of Gas for

Customer on any day during the Summer Period in excess of Customer's Maximum

Daily Injection Quantity or to withdraw quantities of Gas from Storage for

Customer on any Day during the Winter Period in excess of Customer's Maximum

Daily Withdrawal Quantity or to withdraw quantities of Gas from Storage for

Customer for any Month during the Winter Period in excess of Customer's

Monthly Maximum Withdrawal. Customer may also request Pipeline to inject

quantities of Gas for Storage for Customer on any Day during the Winter

Period or withdraw quantities of Gas from Storage for Customer on any Day

during the Summer Period. Customer may request Pipeline to accept deliveries

of quantities of Gas in excess of the Maximum Seasonal Quantity during any

Summer Period and Customer may request Pipeline to redeliver quantities of

Gas in excess of the Maximum Seasonal Quantity during any Winter Period;

provided, however, that at no time may Customer's Working Storage Gas exceed

Customer's Maximum Seasonal Quantity. Pipeline may do so on an interruptible

basis if it can do so without adverse effect on Pipeline's operations or its

ability to meet all other service obligations. Customer shall pay an Overrun

Service charge pursuant to Section 4.2 of this Rate Schedule ISS-M for such

overrun storage service.

4.2 Overrun Service Charge: The Overrun Service Charge shall be paid for each

MMBtu of gas which is injected or withdrawn on behalf of Customer during the

Month in excess of Customer's MDIQ or MDWQ unless such overrun service, with

Pipeline's concurrence, is make-up of quantities of Gas that Pipeline

previously failed to inject into storage or withdraw from storage. The ISS-M

Overrun Service Rate is a negotiated market based rate as provided in the

ISS-M Agreement between Customer and Pipeline.

5. Transfer of Gas in Place

Pipeline shall permit transfers of title of gas in inventory provided both Customers

have executed service agreements under these Rate Schedules ISS-M, ISS, FSS-M, FSS,

NNS, or NNL, both have executed transportation service agreements which will permit

the delivery of the gas, and such transfer does not result in either customer

exceeding its Maximum Seasonal Quantity.
