Forward-Looking Statements
Statements in this release that are not strictly historical in nature are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements about the ability of our common stock to be quoted on the OTCQB, our continued negotiations with our bondholders; the consequences of the failure to reach agreement with the bondholders on acceptable terms; our inability to meet our obligations under the transaction documents related to our corporate restructuring; and our Chapter 11 filing for bankruptcy. Such forward-looking statements also include, but are not limited to, the potential adverse impact of the Chapter 11 proceedings on our business, financial condition or results of operations, including our ability to maintain contracts and other relationships that are critical to our business and the actions and decisions of our creditors and other third parties with interests in our Chapter 11 proceedings; our ability to maintain adequate liquidity to fund our operations during the Chapter 11 proceedings and to fund a plan of reorganization and thereafter, including obtaining sufficient debtor-in-possession and "exit" financing; maintaining normal terms with our vendors and service providers during the Chapter 11 proceedings and complying with the terms of our financing agreements; our ability to obtain court approval with respect to motions in the Chapter 11 proceedings prosecuted from time to time and to develop, prosecute, confirm and consummate our plan of reorganization and the transactions contemplated by such plan; general economic conditions, including changes in interest rates; the timing and expenses related to internal restructurings, and restructuring of terms of existing bonds; and those factors identified in our filings with the SEC. Such forward-looking statements involve known and unknown risks, uncertainties, and other factors that may cause the actual results of Molecular Insight to be materially different from historical results or from any results expressed or implied by such forward-looking statements. The risks and uncertainties and the terms of any reorganization plan ultimately confirmed can affect the value of our various pre-petition liabilities, common stock and/or other securities. No assurance can be given as to what values, if any, will be ascribed in the bankruptcy proceedings to each of these constituencies. A plan of reorganization could result in holders of our liabilities and/or securities receiving no value for their interests. Because of such possibilities, the value of these liabilities and/or securities is highly speculative. Accordingly, we urge that caution be exercised with respect to existing and future investments in any of these liabilities and/or securities. Investors and other interested parties can obtain information about our court filings and claims information on www.omnimgt.com/molecular.
