GENERAL TERMS AND CONDITIONS (Cont'd)

50 OPERATIONAL TRANSACTIONS

50.1 Transporter may buy, sell and/or borrow or tender gas for return at a later date (an "Operational

Transaction") to the extent necessary to:

(i) maintain system pressure and line pack;

(ii) manage system imbalances;

(iii) perform other operational functions of Transporter in connection with transportation,

storage, and other similar services;

(iv) otherwise protect the operational integrity of Transporter's system.

Any Operational Transaction will be made on an unbundled basis and the purchaser of gas sold or

tendered by Transporter will be responsible for any transportation. Sales by Transporter will be made at

receipt point(s), which may include Pooling Points or Aggregation Points as defined in Transporter's IPP or AS

Rate Schedules or at the points of interconnection with the upstream pipelines prior to receipt into

Transporter's system. Other Operational Transactions will be made at locations where the gas may be most

operationally needed from time to time. Operational Transactions will have a lower priority than firm service.

50.2 Transporter will post its quantities for sale, borrow or tender for bidding on its electronic bulletin

board in accordance with the applicable bidding provisions which will be posted at the time of the sale, borrow

or tender offer. Transporter reserves its right, in its sole discretion,

(i) to withdraw its postings

(ii) reject all bids due to operational changes; and

(iii) reject any bids which do not meet or which contain modifications to the terms of the

posting or which contain terms that are operationally unacceptable.

50.3 Transporter will file a report on or before March 1 of each year reflecting the Operational

Transactions for the 12-month period ending the preceding December 31. The report will indicate:

(i) whether the Operational Transaction was a purchase, sale, borrow or tender;

(ii) the source of the gas in the Operational Transaction;

(iii) the date of the Operational Transaction; (for borrows and tenders, Transporter will include

the beginning and termination date of the transaction);

(iv) volumes;

(v) the Operational Transaction price, expressed as a rate per dekatherm;

(vi) the costs and revenues from the Operational Transaction;

(vii) the disposition of the associated costs and revenues, including their absorption by

Transporter;

(viii) an explanation of the purpose of any Operational Transaction; and

(ix) whether Transporter exercised its rights under Sections 50.2(i) and (ii).
