These statements involve known and unknown risks, uncertainties and other factors that may cause actual results, performance, achievements or prospects to be materially different from any future results, performance, achievements or prospects expressed in or implied by such forward-looking statements. In some cases you can identify forward-looking statements by terminology such as ''may'', ''will'', ''should'', ''would'', ''expect'', ''intend'', ''plan'', ''anticipate'', ''believe'', ''estimate'', ''predict'', ''potential'', ''seem'', ''seek'', ''future'', ''continue'', or ''appear'' or the negative of these terms or similar expressions, although not all forward-looking statements contain these identifying words. No specific assurances can be given with respect to whether: Auxilium will succeed in its efforts in defense of the patents covering Testim, including enforcement of its intellectual property rights and approved labeling, whether USL will be subject to a 30-month stay of its efforts to launch a generic competitor to Testim, the timing of any such launch by USL or the expected duration of any patent covering Testim. Although forward-looking statements are based on Auxilium's current plans or assessments that are believed to be reasonable as of the date of this press release, they inherently involve certain risks and uncertainties. These forward-looking statements are subject to a number of risks and uncertainties, including those discussed under ''Risk Factors'' in Auxilium's Annual Report on Form 10-K for the year ended December 31, 2011, each of Auxilium's Quarterly Reports on Form 10-Q for the three months ended September 30, 2012, June 30, 2012 and March 31, 2012 and Auxilium's preliminary prospectus supplement and Current Report on Form 8-K, each filed with the Securities and Exchange Commission (the "SEC") on January 23, 2013.

Auxilium's SEC filings may be accessed electronically by means of the SEC's home page on the Internet at http://www.sec.gov.
