About Biotechnology Value Fund, L.P. Founded in 1993, Biotechnology Value Fund, L.P. is a San Francisco-based investment fund focused on undervalued investment opportunities in the biotechnology sector. About Avalon Pharmaceuticals Avalon Pharmaceuticals is a biopharmaceutical company focused on the discovery and development of small molecule therapeutics for the treatment of cancer. Avalon seeks to discover and develop novel therapeutics through the use of a comprehensive, innovative and proprietary suite of technologies based upon large-scale gene expression analysis which it calls AvalonRx(R). This platform facilitates drug discovery by expanding the range of therapeutic targets for drug intervention, including targets and target pathways frequently consider intractable using conventional HTS approaches, allows more informed decisions about which compounds to advance towards clinical trials, and facilitates drug development through identification of biomarkers of efficacy that can stratify patients or provide early indicators of response. Avalon Pharmaceuticals was established in 1999 and is headquartered in Germantown, Maryland. This announcement contains, in addition to historical information, certain forward-looking statements that involve risks and uncertainties, in particular, related to use of the proceeds of the offering in future drug discovery programs, the potential to expand Avalon's cancer pipeline, the ability to take greater advantage of the AvalonRx(R) engine and clinical progress in the development of AVN944. Such statements reflect the current views of Avalon management and are based on certain assumptions. Actual results could differ materially from those currently anticipated as a result of a number of factors, risks and uncertainties including the risk that the discovery programs may not be successful, the cancer pipeline may not be expanded from the proceeds of the offering, Avalon may not be able to take greater advantage of the AvalonRx(R) engine and AVN944 will not progress successfully in its clinical trials, and other risks described in our SEC filings. There can be no assurance that such development efforts will succeed, that AVN944 will receive required regulatory clearance or, even if such regulatory clearance is received, that any subsequent products will ultimately achieve commercial success.
