2012 Restructuring In January 2012, the Company implemented a restructuring designed to sharpen its focus on value-creating opportunities led by gevokizumab and its unique antibody discovery and development capabilities. The restructuring plan includes a reduction of XOMA's personnel by 84 positions, or 34%, of which approximately 50 were eliminated immediately and the remainder will be eliminated by April 6, 2012. The Company anticipates taking one-time charges for restructuring and related severance costs totaling approximately $6.0 million during 2012. These staff reductions result primarily from the Company's decisions to utilize a contract manufacturing organization for Phase 3 and commercial antibody production and to eliminate internal research functions that are non-differentiating or that can be obtained cost-effectively by contract service providers. Acquisition of U.S. Rights to Perindopril Franchise On January 17, 2012, the Company announced that it had acquired U.S. rights to the perindopril franchise from Servier. The agreement includes ACEON® (perindopril erbumine), a currently marketed angiotensin converting enzyme (“ACE”) inhibitor, and a portfolio of three fixed-dose combination product candidates where perindopril is combined with another active ingredient(s), such as a calcium channel blocker. The Company assumed commercialization activities for ACEON® in January 2012 following the transfer from Servier's previous licensee. In late February 2012, the Company initiated enrollment in a Phase 3 trial for perindopril arginine and amlodipine besylate, the first fixed-dose combination product candidate. The trial, named PATH (Perindopril Amlodipine for the Treatment of Hypertension), is expected to enroll approximately 816 patients with hypertension to determine the safety and efficacy of the fixed dose combination versus either perindopril or amlodipine alone. Based on regulatory interaction to date, if positive, this trial is expected to be the only additional efficacy trial needed to complement the existing clinical data in support of the submission of an application to the FDA seeking approval for this product candidate. Partial funding for the PATH trial will be provided by Servier; the balance of study expenses, consisting primarily of costs generated by the Company's contract research organization, are expected to be paid over time from the profits generated by our ACEON® sales. Underwritten Offering and Amendment to Shareholder Rights Plan On March 9, 2012, the Company completed an underwritten public offering of 29,669,154 shares of its common stock, and accompanying warrants to purchase one half of a share of common stock for each share purchased, at a public offering price of $1.32 per share. Total gross proceeds from the offering were approximately $39.2 million, before deducting underwriting discounts and commissions and estimated offering expenses totaling approximately $3.0 million. The warrants, which represent the right to acquire an aggregate of up to 14,834,577 shares of common stock, are immediately exercisable and have a five-year term and an exercise price of $1.76 per share. The Company has amended its shareholder rights agreement to provide that it will not apply to any person or entity who becomes the beneficial owner of 20% or more but less than 40% of its outstanding common stock with the prior approval of its board of directors, and its board has approved purchasers in the recent public offering becoming beneficial owners of 20% or more but less than 40% of its outstanding common stock as a result of their participation in the offering. As a result, such ownership by any such purchaser will not trigger the provisions of the rights agreement that would give each holder of the rights the right to receive upon exercise that number of common share equivalents having a market value of two times the exercise price. The board's approval in this regard only applies to purchasers in such offering.
