 6.6 Term Extension: Notwithstanding the provisions of this Agreement, in the event there is a cumulative Imbalance
(“Cumulative Imbalance”) between receipts and deliveries at the end of the Contract Term, the Contract Term of the Agreement will be extended by extending deliveries or receipts, as applicable, until such Cumulative Imbalance is eliminated
or by such method as is then mutually agreed upon by the Parties hereto. 
 ARTICLE 7 
 IMBALANCES 
 7.1 Balancing: The Shipper shall use all reasonable efforts to at all times maintain balance, based on the best
available information, between the gas received to the Shipper’s account at the Receipt Point, net of Fuel, and the gas delivered by the Terasen Gas from the Shipper’s account at the Delivery Point. Any difference between gas received and
delivered on a given Day, will be considered an Imbalance for the Day. In the event the gas received exceeds that delivered, then the Imbalance will be considered a pack (“Pack Imbalance”). In the event the gas delivered exceeds that
received then the Imbalance will be considered a draft (“Draft Imbalance”). 







 7.2 Tracking Imbalances: In the event that Terasen Gas determines that there is a Pack Imbalance or Draft Imbalance on a
Day, that amount will be accumulated with the Pack Imbalances and Draft Imbalances for previous Days and tracked as a Cumulative Imbalance. 
 7.3
Communication of Imbalances: Terasen Gas or its agent will communicate any Pack Imbalance, Draft Imbalance, and the Cumulative Imbalance each Day together with the Authorized Quantity as set out in Section 6.2. 
 7.4 Imbalance Remedy: If Terasen Gas determines that a Shipper has a Pack Imbalance or Draft Imbalance, Terasen Gas at any point may request that the Shipper remedy, in
whole or in part, such Imbalance within the next Day or other such timeframe that is agreed on by the Parties. Shipper will reduce Pack Imbalances by placing requests with Terasen Gas for Imbalance return (“Imbalance Return”) and will
reduce Draft Imbalances by placing requests for Imbalance payback (“Imbalance Payback”). These requests shall be considered Imbalance Nominations and are Subject to the Nomination rules and deadlines pursuant to Article 6. Imbalance
Nominations that are Shipper’s response to Terasen Gas’ request that the Shipper remedy an Imbalance under this Section 7.4 shall be of higher priority than all other Nominations. The Cumulative Imbalance will be increased or
decreased accordingly by the Imbalance Paybacks and Imbalance Returns authorized for the Day. 
 7.5 Adjustment of Receipts and Deliveries: In the event the
Shipper does not submit Nominations to remedy an Imbalance as requested by Terasen Gas pursuant to Section 7.4, Terasen Gas has the right to adjust the receipts and deliveries of Shipper’s gas to the extent needed to remedy the Imbalance.

 7.6 Penalties: If Terasen Gas has requested that Shipper remedy any Imbalance pursuant to Section 7.4, and the Shipper fails to comply, then to the
extent that Terasen Gas was not successful in remedying the Imbalance, the Shipper shall pay to Terasen Gas a fee equal to the Imbalance amount not remedied expressed in GJs, multiplied by the greater of the Sumas Daily Absolute High plus 10% or the
Kingsgate Daily Absolute High plus 10% for the Day that the Imbalance was to be remedied. In the event the Shipper is assessed a penalty, the Shipper’s Cumulative Imbalance will be adjusted accordingly by the amount of gas on which the Shipper
was assessed the penalty. 
 7.7 Error on Terasen Gas’ Part: If an Imbalance is created as a result of an error on the part of the Terasen Gas or its
designated agent during the scheduling process, then Terasen Gas must eliminate the Imbalance the next Day unless otherwise agreed to by the Parties. If the Imbalance caused by the Terasen Gas’ error is not eliminated the next Day, then Terasen
Gas shall pay to the Shipper a fee equal to the amount of the unresolved Imbalance multiplied by the greater of the Sumas Daily Absolute High plus 10% or the Kingsgate Daily Absolute High plus 10% for the Day the imbalance was created. Payment of
this penalty would result in the Cumulative Imbalance amount being adjusted accordingly by the amount of gas on which the Terasen Gas was assessed a penalty. 







 7.8 Potential for Future Changes to Balancing Requirements: The Parties recognize that Duke may obtain NEB approval for
changes to the balancing provisions set out in the Duke General Tenns and Conditions that may result in balancing penalties beyond those currently provided for in the current Duke General Tenns and Conditions. In this event, Terasen Gas reserves the
right to recover any such penalty costs assessed to Terasen Gas as a result of the Shipper failing to take delivery of the Authorized Quantity for a Day. 
 In the event that the Southern Crossing Pipeline system is expanded and the balancing requirements for shippers transporting gas on the expansion capacity are different than the balancing requirements described under
this section 7, the balancing requirements set out in this Section 7 shall be modified to align with the balancing provisions for the expansion capacity. 
 ARTICLE 8
