WeissLaw LLP Files a Class Action Lawsuit Challenging the Acquisition of Onyx
Pharmaceuticals, Inc. by Amgen Inc. -- ONXX

NEW YORK, Aug. 30, 2013 (GLOBE NEWSWIRE) -- WeissLaw LLP, a leading
shareholder rights law firm, announces that it has filed a class action
complaint in the Delaware Court of Chancery challenging the proposed
acquisition of Onyx Pharmaceuticals, Inc. (Nasdaq:ONXX) by Amgen Inc.

The Complaint Challenges the Inadequate Price to Be Paid to Onyx Shareholders

The complaint focuses on the failure of Onyx's Board of Directors to maximize
value for its shareholders. Specifically, the complaint alleges:

  *despite the Company publicly rejecting Amgen's unsolicited proposal to
    acquire Onyx for $120 per share, on June 30, 2013, proclaiming that "Onyx
    has tremendous momentum" and that the "price proposed by Amgen
    significantly undervalued Onyx and its prospects, and was not in the best
    interest of Onyx and its shareholders", now, less than two months later,
    the Board has agreed to sell the Company for a mere $5 per share over the
    admittedly "significantly" inadequate price of $120;
  *the $125 offer price represents a discount to Onyx's closing price of
    $125.90, as recently as August 14, 2013, and a significant discount to
    Onyx's closing price of $136.03 on July 5, 2013; and
  *the $125 offer price is significantly below target prices for the
    Company's stock set by analysts after Amgen's unsolicited $120 offer was
    announced, with a high target set at $160, with one analyst noting that
    the acquisition is "a steal for Amgen."

Given these facts, and Onyx shareholder represented by WeissLaw LLP filed the
complaint challenging Onyx's Board's decision to sell the Company to Amgen now
rather than allow shareholders to continue to participate in the Company's
continued success and future growth prospects.
