There can be no assurance that the Company will successfully complete a transaction as part of the strategic alternative process, and any such transaction, if available, may not be on terms favorable to the Company. If the Company is not able to successfully complete any transaction, the Company’s business, operations and financial condition will be materially adversely affected, and the Company would be forced to discontinue its business and operations entirely, wind-up and liquidate.
