Forward Looking Statements This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other federal securities laws. Any statements contained herein which do not describe historical facts, including but not limited to: the preliminary nature of the data being reported in this press release, the fact that no new Feraheme safety signals were identified, our expectation to seek approval for Feraheme for treatment of the broader population of patients with iron deficiency anemia and a history of an unsatisfactory response to oral iron therapy, our belief that Feraheme could be a valuable therapeutic alternative to currently approved IV irons for the treatment of their iron deficiency anemia, and our intent to submit a supplemental new drug application for the broad IDA indication to the U.S. Food and Drug Administration by year-end 2012. Such risks and uncertainties include: (1) uncertainties regarding our and Takeda's ability to successfully compete in the intravenous iron replacement market both in the U.S. and outside the U.S., (2) uncertainties regarding our ability to successfully and timely complete our clinical development programs and obtain regulatory approval for Feraheme in the broader IDA indication both in the U.S. and in territories outside of the U.S., including the European Union, (3) the fact that significant safety or drug interaction problems could arise with respect to Feraheme, (4) the risk that final data from the clinical trial described herein could differ materially from or be subject to differing interpretations by regulatory authorities than set forth in this press release, (5) uncertainties regarding our ability to manufacture Feraheme, (6) uncertainties relating to our patents and proprietary rights, and (7) other risks identified in our Securities and Exchange Commission filings, including our Quarterly Report on Form 10-Q for the three months ended March 31, 2012.
