About Massachusetts Biologic Laboratories.

Established over 100 years ago to serve the public health interests of the Commonwealth of Massachusetts, the Massachusetts Biologic Laboratories (MBL) develops and manufactures vaccines and other biologic products; since 1997, MBL has been a part of the University of Massachusetts. The MBL is the only publicly operated, FDA-licensed, vaccine manufacturing facility in the country still operated by a state government agency. Throughout its history, the labs have introduced into general statewide use vaccines to prevent diphtheria, pertussis, tetanus and other diseases.

In 2005, MBL opened a new facility with a state-of-the-art aseptic filling operation that will fill vials of vaccine and other therapeutics manufactured at the MBL. The building also houses a major new monoclonal antibody manufacturing operation. Both aseptic filling and monoclonal antibody manufacturing capacity are in short supply in the United States; the new facility will allow MBL to continue to fill its own products as well as offer this limited resource for both private and public needs.

Materials in this press release may contain information that includes or is based upon forward-looking statements within the meaning of the Securities Litigation Reform Act of 1995. Forward-looking statements give our expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. They use words such as "anticipate," "estimate," "expect," "project," "intend," "plan," "believe," and other words and terms of similar meaning in connection with a discussion of future operating or financial performance. In particular, these include statements relating to future steps we may take, prospective products, future performance or results of current and anticipated products, sales efforts, expenses, the outcome of contingencies such as legal proceedings, and financial results.

Any or all of our forward-looking statements here or in other publications may turn out to be wrong. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. Many such factors will be important in determining our actual future results. Consequently, no forward-looking statement can be guaranteed. Our actual results may vary materially, and there are not guarantees about the performance of our stock.

Any forward-looking statements represent our expectations or forecasts only as of the date they were made and should not be relied upon as representing our expectations or forecasts as of any subsequent date. We undertake no obligation to correct or update any forward-looking statements, whether as a result of new information, future events or otherwise, even if our expectations or forecasts change. You are advised, however, to consult any further disclosures we make on related subjects in our reports filed with the SEC. In particular, you should read the discussion in the section entitled "Cautionary Statement Regarding Forward-Looking Statements" in our most recent Annual Report on Form 10-K, as it may be updated in subsequent reports filed with the SEC. That discussion covers certain risks, uncertainties and possibly inaccurate assumptions that could cause our actual results to differ materially from expected and historical results. Such factors include, but are not limited to, risks and uncertainties relating to the resolution of the FDA compliance issues at our Decatur, Illinois manufacturing facility. Other factors besides those listed there could also adversely affect our results.
