“As reflected in our revised 2012 selling, general and administrative expense guidance, over the next several months we intend to expand our selling capacity by increasing our GE-focused sales force from its current size of 160 sales representatives to 192 sales representatives. Additionally, over the past several quarters we have expanded our institutional sales force from 25 key account managers (KAMs) to its current size of 40 KAMs.“The expanded 192-member sales force will continue to focus primarily on gastroenterologists, colorectal surgeons and hepatologists. One 96-member division of the GE sales force will promote XIFAXAN 550 for hepatic encephalopathy, RELISTOR and APRISO. The second 96-member division of the GE sales force will promote SOLESTA for fecal incontinence, XIFAXAN 550 for hepatic encephalopathy, MOVIPREP/OSMOPREP – our bowel cleansing products – and APRISO. The KAMs will promote XIFAXAN 550 for hepatic encephalopathy, RELISTOR and DEFLUX. “Our core business is strong and growing. In the near term we believe we can generate $1 billion in revenue in 2013, assuming the July 27, 2012 approval of subcutaneous injection RELISTOR for OIC in chronic, non-cancer pain and excluding the potential XIFAXAN IBS indication. Our portfolio of marketed products is complemented by our impressive pipeline of product candidates in development that should drive additional revenue growth over the long term as they are commercialized. Additionally, the Company continues to actively pursue additional product opportunities to expand and broaden our product portfolio. We are extremely pleased with the success we have achieved to date and we believe the Company is well-positioned to continue to succeed in our mission of being the leading specialty pharmaceutical company licensing, developing and marketing innovative products to healthcare professionals to prevent or treat gastrointestinal disorders.” The Company will host a conference call at 5:00 p.m. ET, on Monday, May 7, 2012.
