in the event of a breach of a Firm or Interruptible obligation to deliver or receive gas shall be recovery of the following:"

14.12
INDEX TRANSACTIONS. The following provisions shall be applicable to Transactions where the Contract Price for a Transaction is determined by

14.12.1
MARKET DISRUPTION. If a Market Disruption Event (as defined below) occurs during the Determination Period (as defined below), the Floating Price
(as defined below) for the affected Trading Day(s) (as defined below) shall be determined pursuant to the Floating Price specified in the Transaction for the first Trading Day thereafter on which no

(i) the failure of the Price Source to announce or publish information necessary for determining the Floating Price; (ii) the failure of trading to commence or the permanent

(iii) the temporary or permanent discontinuance or unavailability of the price Source; (iv) the temporary or permanent closing of any Exchange specified for determining a Floating Price;
or (v) a material change in the formula for or the method of determining the Floating Price. "Price Source" means, in respect of a Transaction, the publication (or such other origin of

Transaction. "Determination Period" means each calendar Month a part or all of which is within the Delivery Period of a Transaction. "Trading Day" means a day in respect of which the relevant Price

may notify the other Party of (i) that correction and (ii) the amount (if any) that is payable as a result of that correction. If a Party gives Notice that an amount is so payable, the
Party that originally either received or retained such amount will, not later than two Business Days after the effectiveness of that Notice, pay subject to any applicable conditions precedent, to the
other Party that amount, together with interest at the Interest Rate for the period from and including the day on which payment originally was (or was not) made to but excluding the day of payment of
