The third-party outages consisted of a shutdown of a required the company to scale back mine production
cogeneration facility, which resulted in limited steam particularly in the second quarter of 2013 to coincide with
limited upgrader availability during the Upgrader 1
availability and required a three-day shutdown of
Upgrader 2 in early May and constrained production until turnaround. In 2012, mining activity was also constrained
by low upgrader availability and lower ore grade quality of

Production of upgraded product in 2012 was impacted by
planned maintenance on various coker units and 2012, and increased primarily due to the commissioning of
replacement well pads in 2013 and increased planned
hydrotreating units in Upgrader 1 and 2, as well as
unplanned maintenance relating to primary and secondary maintenance in the prior year, partially offset by the impact
of third-party outages in 2013.
