## Fort Hills Energy Limited Partnership 

In November 2005, we acquired a 15% interest in the Fort Hills Energy Limited Partnership, which is developing the Fort Hills oil sands project in Alberta, Canada. Fort Hills is our only significant investment in an associate. As consideration for our initial 15% interest, we contributed 34% of the first $2.5 billion of project expenditures. In September 2007, we acquired an additional 5% interest, bringing our interest to 20%. In consideration for our additional 5% interest, we are required to contribute 27.5% of project expenditures after project spending reaches $2.5 billion and before project spending reaches $7.5 billion. Thereafter, we are responsible for funding our 20% share of development costs. In the event that the project is abandoned, all limited partners are required to make additional contributions such that the aggregate contributions of all partners equal $7.5 billion and any unexpended amount will be distributed to the partners according to their partnership interests. Project spending totalled $3.3 billion as of December 31, 2012, of which our share was $1.1 billion.
