While Tekmira considers these assumptions to be reasonable, these assumptions are inherently subject to significant business, economic, competitive, market and social uncertainties and contingencies.Additionally, there are known and unknown risk factors which could cause Tekmira's actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements contained herein. Known risk factors include, among others: the possibility that Marqibo might not prove to be a safe and effective alternative for the treatment of adult relapsed ALL compared to existing therapies; Marqibo will not be accepted in the marketplace; Talon will not be able to develop adequate marketing and distribution capabilities; Talon will not be able to secure the additional capital necessary to fund its product development and commercialization programs; Tekmira may not receive milestone and royalty payments based on the successful development and commercialization of Talon's Marqibo, Brakiva, and Alocrest product candidates; and Tekmira's development programs will not result in expected results on a timely basis, or at all.
