IBS RATE SCHEDULE

INTERRUPTIBLE BALANCING SERVICE

(Continued)

(b) The storage of Gas in amounts up to the Maximum Balance Quantity set forth

in Exhibit B to Customer's Hub Services Agreement, provided that all higher priority service

storage and system needs have been satisfied; or

Customer's nomination to the Point(s) of Delivery located on Egan Hub's system which is in

excess of the quantity of Gas received by Egan Hub at any Point(s) of Receipt per Customer's

nomination under rate schedules set forth in this FERC Gas Tariff, provided that (i) all higher

priority service nominations for withdrawal and system needs have been satisfied, and (ii)

Customer or Egan Hub has sufficient Gas Stored in Interruptible Storage Inventory.

2.3 To the extent Interruptible storage capacity or Gas which is being utilized by a

Customer pursuant to this rate schedule is needed by Egan Hub in order to satisfy Egan Hub's

obligations to firm FSS Customers and/or secondary firm SSS Customers, Egan Hub shall require

Customer to withdraw or return all, or any portion of, the IBS Gas quantities held or loaned by

Egan Hub for the account of Customer as specified by Egan Hub. Egan Hub's notice to Customer

may be given verbally, but shall be confirmed in writing via e-mail to Customer. Such notice

shall specify the quantity required to be withdrawn or returned and the date by which the

withdrawal or return must be completed. Unless Egan Hub otherwise agrees, Customer shall be

required to make ratable injections or withdrawals. If Customer fails to withdraw such IBS

storage Gas, then Egan Hub may take, free and clear of any adverse claims, title to such IBS

Storage Inventory as Customer was instructed, but failed, to withdraw. If Customer fails to

inject such IBS storage Gas, then Egan Hub may purchase replacement Gas and Customer shall pay

Egan Hub the cost of the replacement Gas, which includes the actual cost of replacement

supplies and any costs or penalties incurred by Egan Hub or its Customers as a result of

Customer's failure to deliver replacement Gas, plus all other costs incurred by Egan Hub to

secure such replacement Gas, including, but not limited to, third-party marketing fees,

transportation by third-party pipeline companies, and all other costs for securing replacement

Gas. In the event that Egan Hub retains and takes title to any of Customer's Gas pursuant to

this Section 2.3, Egan Hub shall dispose of such Gas by auction in accordance with Section 33

of the General Terms and Conditions of this FERC Gas Tariff and shall remit to Customer the

proceeds received from such auction less Interruptible Balancing Charges for the period from

the first day following the date on which Customer was required to complete the withdrawal

until the Gas is sold to the highest bidder and any applicable Fuel Reimbursement charges,

Interruptible Balancing Withdrawal Charges and any administrative costs incurred by Egan Hub to

conduct the auction. Such Interruptible Balancing Charges shall be calculated by multiplying

the Interruptible Balancing Charge rate in effect on the required withdrawal date by the

quantity of Gas sold at auction.
