"(a) In respect of Dilbit Customer Product movements, no later than three (3) Business Days prior to applicable forecast or information reporting requirement deadlines prescribed by the Crude Oil Logistics Committee (www.colcomm.com) for each month, USD will notify Gibson of the proposed schedule of Dilbit shipments to the Rail Terminal beginning on the 1st day of the following month and shall request its Dilbit Customer to also notify Gibson of its nomination from the Gibson Terminal for the movements of Dilbit from the Gibson Terminal directly to the Rail Terminal for such month. USD will also immediately notify Gibson (and will cause its Dilbit Customer to notify Gibson) of any revision to the initial scheduled volume which was communicated to Gibson the previous month.

(b) Nomination notices shall include:

(i) the period during which deliveries will need to be made;

(ii) the grade and quantity of Dilbit to be delivered;

(iii) estimated time of commencement of each delivery;

(d) USD will update Gibson real time on the Dilbit volume required to complete each individual batch to accommodate the actual Dilbit railcars being loaded. This will occur as the final cut of railcars are being loaded for each train and is to give Gibson the information necessary for Gibson to make the switch at the Gibson Terminal in order for the Product to be loaded on the next train to be delivered as linefill into the Pipeline Facilities to push the Product into the railcars to complete the current train loading. All nominations and scheduling notices shall be in writing to:
