You are cautioned not to place undue reliance on forward-looking statements, as there can be no assurance that the plans, intentions or expectations upon which they are based will occur.  By their nature, forward-looking statements involve numerous assumptions, known and unknown risks and uncertainties, both general and specific, that contribute to the possibility that the predictions, forecasts, projections and other forward-looking statements will not occur.  Although Canadian Oil Sands believes that the assumptions and expectations represented by such forward-looking statements are reasonable and reflect the current views of Canadian Oil Sands with respect to future events, there can be no assurance that such assumptions and expectations will prove to be correct.

The factors or assumptions on which the forward-looking information is based include, but are not limited to: the assumptions outlined in Canadian Oil Sands’ guidance document as posted on this website as of the date hereof and as subsequently amended or replaced from time to time, including without limitation, the assumptions as to production, operating expenses and oil prices; the successful and timely implementation of capital projects; Syncrude's major project spending plans; the ability to obtain regulatory and joint venture owner approval; our ability to either generate sufficient cash flow from operations to meet our current and future obligations or obtain external sources of debt and equity capital; the continuation of assumed tax, royalty and regulatory regimes and the accuracy of the estimates of our reserves and resources volumes.

Some of the risk and other factors which could cause actual results or events to differ materially from current expectations expressed in the forward-looking statements contained on this website and in the documents on this website include, but are not limited to: the impacts of legislative or regulatory changes especially as such relate to royalties, taxation, the environment and tailings; operational risks in producing synthetic crude oil ("SCO"); the uncertainty of estimates and projections relating to production, operating expenses and oil prices; potential delays or changes in plans with respect to expansion projects or capital expenditures; the ability to operate and maintain a complex integrated mining and upgrading operation; uncertainties as to the availability and cost of financing; fluctuations in oil and gas prices and foreign currency exchange rates; the possibility that government policies may change or governmental approvals may be delayed or withheld; the impact of technology on operations and processes and how new complex technology may not perform as expected; skilled labour shortages and the productivity achieved from labour in the Fort McMurray area; the supply and demand metrics for oil and natural gas; the impact that pipeline capacity and refinery demand have on prices for our product; the unanimous joint venture owner approval for major expansions and changes in product types; the variances of stock market activities generally; normal risks associated with litigation, general economic, business and market conditions; Canadian Oil Sands’ ability to either generate sufficient cash flow from operations to meet our current and future obligations or obtain external sources of debt and equity capital; the impact of Syncrude being unable to meet the conditions of its approval for its tailings management plan under Directive 074; imprecision of reserve and resource estimates; the volatility of the SCO to West Texas Intermediate differential and such other risks and uncertainties described in our Annual Information Form dated February 21, 2013 and in the reports and filings made with the securities regulatory authorities from time to time by Canadian Oil Sands which are available on Canadian Oil Sands’ profile on SEDAR at www.sedar.com and on this website.

You are cautioned that the foregoing list of important factors is not exhaustive.  Furthermore, the forward-looking statements contained on this website are made as of the date noted on the website posting and unless required by law, Canadian Oil Sands does not undertake any obligation to update publicly or revise any of the included forward-looking statements, whether as a result of new information, future events or otherwise.
