The Company terminated its $10 million credit facility with General Electric Capital Corporation, as agent, and GE Capital Bank and certain other institutions, as lenders, in February 2016.

There can be no assurance that such financing will be available on terms acceptable to the Company, or at all. The Company also has the ability to defer certain product development and other programs, if necessary. The Company believes that its existing capital resources will be sufficient to support its current business plan and operations beyond April, 2018.
