Largent, 57, has 30 years of management experience in the medical device and pharmaceutical industries, including 28 years with Irvine, CA-based Allergan Inc. During that period, he gained extensive experience in marketing, business development and strategic planning. For the past five years, Largent has been a consultant to the medical device industry helping clients to build shareholder value by creating sustainable revenue and earnings growth. In this role, he led a lobbying effort for Aliso Viejo, CA-based eyeonics, Inc., an ophthalmic device company, that resulted in the Centers for Medicare & Medicaid Services (CMS) issuing an important new policy allowing for patient shared billing.

Chairman George V. d’Arbeloff said, “We look forward to Jim joining the Board and bringing his reputable experience to bear as we drive to reach our revenue and profitability goals for 2007 and future years. Jim is an exceptional addition to our Board and his advice and participation will be extremely valuable.”

Largent has extensive direct experience in medical devices that began at Piscataway, NJ-based Pharmacia Ophthalmics where he was responsible for launching its U.S. intraocular lens business. Largent also spent a decade during his career at Allergan in its ophthalmic surgical device business where he held progressively responsible positions before the $200 million business was spun out in 2002 as part of Santa Ana, CA-based Advanced Medical Optics. In his last position in the device business at Allergan, he was responsible for global strategic marketing, business development, R&D and manufacturing. Largent spent his last six years with Allergan as Vice President, Strategic Planning in the Corporate Development Department where he was responsible for corporate level strategic planning and business development. Largent currently serves as a director of Newport Beach, CA-based World Am, Inc., a publicly traded start-up technology company.
