& #8226; Amgen Inc.

and Fremont-based Abgenix Inc. have been hit by a shareholder class-action lawsuit that claims Amgen’s $2.2 billion buyout offer for its rival is “inadequate.” The complaint, filed in the Superior Court of the State of California in Alameda County, accuses Abgenix’s directors of violating their fiduciary obligations to shareholders in negotiating and approving the merger agreement. The suit seeks an injunction against the proposed merger. Abgenix said it believes the lawsuit “is without merit and intends to vigorously defend the action.”

Last week, Abgenix agreed to be acquired by Thousand Oaks-based Amgen for $22.50 per share in cash. The deal is expected to close by the end of March.
