The securities were offered only to accredited investors. The Company has agreed to file a registration statement with the SEC covering the resale of the shares of common stock issuable upon exercise of the Replacement Warrants.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that involve a number of risks and uncertainties. For those statements, the Company claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as "believes," "expects," "intends," "may," "will," "plans," "potential," "anticipates," or similar expressions. Any forward-looking statements set forth in this press release speak only as of the date hereof. Such forward-looking statements may include: statements relating to the anticipated closing date, the timing of commencement, enrollment, completion, and results of clinical trials; IP expansion and regulatory progress; and timing for receiving government approvals, if at all. The Company does not undertake to update any of these forward-looking statements to reflect events or circumstances that occur after the date hereof, except as required by applicable law. The Company is in various stages of seeking to determine whether Ampligen will be effective in the treatment of multiple types of viral diseases, cancers, and immune-deficiency disorders, and disclosures in the Company's reports filed with the SEC, on its website, and in its press releases set forth its current and anticipated future activities. These activities are subject to change for a number of reasons. Significant additional testing and trials will be required to determine whether Ampligen^® will be effective in the treatment of these conditions. Results obtained in preclinical studies do not necessarily predict results in humans. Human clinical trials will be necessary to prove whether or not Ampligen^® will be efficacious in humans. No assurance can be given as to whether current or planned clinical trials will be successful or yield favorable data, and the trials are subject to many factors including lack of regulatory approval(s), lack of study drug, lack of adequate funding, or a change in priorities at the institutions sponsoring other trials. Even if these clinical trials are initiated, the Company cannot assure that the clinical studies will be successful or yield any useful data. No assurance can be given that the findings in preliminary studies will prove true or that such studies will yield favorable results, or that future studies will not result in findings that are different from those reported in the studies referenced in the Company's reports filed with the SEC, on the Company's website, and in its press releases. Operating in foreign countries carries with it a number of risks, including potential difficulties in enforcing intellectual property rights. The Company cannot assure that its potential foreign operations will not be adversely affected by these risks.

For a detailed discussion of risk factors, please review the "Risk Factors" section in the Company's most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q filed with the SEC. These filings are available at www.sec.gov and www.aimimmuno.com.
