Amalco may be unable to obtain the necessary levels of financing on acceptable terms, or at all, upon the expiration of the existing Petro-Canada and Suncor credit facilities
Upon the expiration in 2013 of the existing Suncor credit facilities and the existing Petro-Canada credit facilities, Amalco may be unable to obtain a level of credit under new credit facilities on a basis equivalent to the borrowing base of the aggregate of such existing Suncor and Petro-Canada facilities on acceptable terms, or at all. If, upon such expirations, Amalco is unable to obtain a level of credit on acceptable terms necessary to fund its operations and capital programs, as currently contemplated, Amalco may not have other sufficient sources of financing which could result in the curtailment of such operations or capital programs. In addition, any new credit facilities that Amalco enters into, or alternative sources of financing that Amalco may obtain, may be on terms that are less favourable than the terms of the existing Suncor credit facilities and the existing Petro-Canada credit facilities, which could have a material adverse impact on Amalco's future financial position, capital projects and growth opportunities.
