Press Release: Ligand Pharmaceuticals Cuts Workforce By 76 Percent

Ligand Pharmaceuticals Cuts Workforce By 76 Percent, Says CFO To Leave SAN DIEGO -- Ligand Pharmaceuticals Incorporated announced today that it is restructuring its business, pursuant to its new business model, by reducing its workforce by about 267 positions or approximately 76 percent. Key elements of the restructuring are as follows: Ligand's headcount following the reduction in force will be approximately 85 people down from a recent level of 352. Included in the 267-position reduction announced today are 40 home office employees and 23 field based employees whose employment was terminated at the beginning of January 2007 and approximately 62 Ligand employees who, under the previously disclosed terms of the agreement with King Pharmaceuticals, Inc., will be offered employment by King upon closing of the sale of AVINZA. Most of the restructuring will take place in the first quarter of 2007, with a small transitional team staying until mid-year. The company's current Chief Financial Officer, Paul V. Maier, will step down effective January 31, 2007. Tod G. Mertes, a vice president and Ligand's current corporate controller, will assume the position of Interim CFO. Associated with the restructuring and refocused business model of the company, several officers have agreed to step down, including the Chief Scientific Officer, General Counsel and the heads of human resources, operations, regulatory affairs and project management. Research and development will continue to be managed by our vice presidents currently in place. The Company's primary operations will be consolidated into one building with the goal to sublet unutilized space. The Company's subsidiary in the United Kingdom will be shut-down as soon as practicable, subject to local employment laws. Severance packages will be provided to employees directly affected by the restructuring. Ligand expects to incur cash restructuring charges of approximately $10 to $12 million primarily associated with one-time employee severance benefits and change in control payments related to the divestiture of AVINZA. This estimate excludes non-cash expenses that would be recognized under SFAS 123 R, Share-based Payment ("SFAS 123 R"), in connection with the accelerated vesting or extension of the exercise period of stock options that is expected to occur under certain change of control employee agreements. Approximately $2.7 million of the estimated cash charge will be recorded in the fourth quarter of 2006 with the balance to be recorded in the first and second quarters of 2007. Additionally, fourth quarter 2006 charges will include approximately $0.3 million of non-cash compensation expense recognized under SFAS 123 R related to changes in stock options for certain employees terminated during that period. On an annualized basis, the operating cash savings to the Company as a result of the eliminated positions is estimated to be $20 to $22 million. This estimate excludes non-cash stock compensation determined under SFAS 123 R. Ligand's collaborations with corporate partners including GlaxoSmithKline, Wyeth, Pfizer, TAP, and Eli Lilly and Ligand's pending sale of AVINZA to King Pharmaceuticals, Inc. are not expected to be affected by the restructuring. Ligand began its initial restructuring process in December of 2006 after the sale of its Oncology division and the sale-leaseback of its facilities. The Company eliminated 63 positions in the fourth quarter of 2006 as a result of these activities. "Ligand is rapidly transforming into a highly focused R&D and royalty driven pharmaceutical company. While it is difficult to let go of employees who have made significant contributions to Ligand over the years, this is a required move to help align our Company's resources with our main projects," said John L. Higgins, President and Chief Executive Officer. "With the completed and pending divestiture of our commercial brands, a reduction in force was expected. I believe we have made important and necessary decisions and, out of respect for all of our employees, I am pleased that we could move through this process expeditiously. We have numerous exciting early stage programs, and I am confident our newly focused team will continue to conduct excellent research and operate a robust business." The Company will provide an outlook for its 2007 operating expenses during its Fourth Quarter 2006 earnings call expected to be held in early March around the filing of our Annual Report on Form 10-K.
