Facet Biotech Advises Stockholders to Take No Action in Response to Biogen Idec's Offer

REDWOOD CITY, CA, Sep 21, 2009 (MARKETWIRE via COMTEX) -- The board of directors of Facet Biotech Corporation (NASDAQ: FACT) today recommended that Facet Biotech's stockholders take no action at this time in response to the announcement by Biogen Idec Inc. (NASDAQ: BIIB) that it has made an unsolicited conditional tender offer to acquire all of Facet Biotech's outstanding shares of common stock for $14.50 per share in cash.

Consistent with its fiduciary duties and in consultation with its independent financial and legal advisors, Facet Biotech's board will review and consider Biogen Idec's offer, and within 10 business days, will advise Facet Biotech's stockholders of the board's position regarding the offer as well as its reasons for that position.

As the rules governing these situations restrict Facet Biotech's communications with stockholders until a formal, detailed response is filed, Facet Biotech will not be participating in the UBS Global Life Sciences Conference in New York on Wednesday, September 23, 2009.

Centerview Partners LLC is acting as financial advisor to Facet Biotech and Simpson Thacher & Bartlett LLP is acting as legal advisor.
