     This Amendment No. 7 to Schedule 13D ("Amendment No. 7") amends the

on March 21, 2007, Amendment No. 2 thereto filed on April 11, 2007, Amendment
No. 3 thereto filed on April 18, 2007, Amendment No. 4 thereto filed on May 22,
2007, Amendment No. 5 thereto filed on May 31, 2007, Amendment No. 6 thereto
filed on July 17, 2007 and this Amendment No. 7, the "Schedule 13D") and is
being filed on behalf of Third Point LLC, a Delaware limited liability company
(the "Management Company" or "Third Point"), Third Point Offshore Fund, Ltd., a
Cayman Islands limited liability exempted company (the "Offshore Fund"), Daniel
S. Loeb, an individual ("Mr. Loeb", and together with the Management Company and
the Offshore Fund, the "Third Point Reporting Persons"), and Jason Aryeh, an
individual ("Mr. Aryeh", and together with the Third Point Reporting Persons,
the "Reporting Persons"). This Amendment No. 7 relates to the common stock, par
value $0.01 per share (the "Common Stock"), of PDL BioPharma, Inc., a Delaware
corporation (the "Company").

     The Management Company is the investment manager or adviser to a variety of
hedge funds and managed accounts (such funds and accounts, including the
Offshore Fund, the "Funds"). The Funds directly own the Common Stock to which
this Schedule 13D relates, and Mr. Loeb and the Management Company may be deemed
to have beneficial ownership over such Common Stock by virtue of the authority
granted to them by the Funds to vote and to dispose of the securities held by
the Funds, including the Common Stock. Mr. Aryeh may be deemed to have
beneficial ownership of the shares of Common Stock directly owned by JALAA
Equities, LP ("JALAA") by virtue of his ability to vote and/or to dispose of the
securities held by JALAA, including the Common Stock.

Item 3.   Source and Amount of Funds or Other Consideration.

     Item 3 of the Schedule 13D is hereby amended and restated as follows:

     The Funds have expended an aggregate of approximately $224,260,930 of their
own investment capital to acquire the 11,300,000 shares of Common Stock held by
them. The Offshore Fund has expended an aggregate of approximately $152,747,490
of its own investment capital to acquire its 7,598,200 shares of Common Stock.
JALAA has expended an aggregate of approximately $20,780 of its own investment
capital to acquire the 1,011 shares of Common Stock that it holds.

Item 4.   Purpose of Transaction.

     Item 4 of the Schedule 13D is hereby amended by adding the following
thereto:

     On August 29, 2007, Third Point sent a letter to the Board of Directors of
the Company, demanding that L. Patrick Gage resign immediately as Chairman and
as a member of the Board and that the Company's management and Board focus on
the prompt sale of the Company.

     A copy of the letter is attached to this Schedule 13D as an exhibit and
incorporated herein by reference in its entirety.

Item 5.   Interest in Securities of the Issuer.

     Items 5(a), 5(b) and 5(c) of the Schedule 13D are hereby amended and
restated as follows:

     (a) As of the date hereof, the Management Company and Mr. Loeb beneficially
own 11,300,000 shares of Common Stock (the "Third Point Shares"). The Third
Point Shares represent 9.7% of the 116,831,008 shares of Common Stock
outstanding as of August 2, 2007, as reported in the Company's Quarterly Report
on Form 10-Q for the quarterly period ended June 30, 2007. The percentages used
herein and in the rest of this statement are calculated based upon this number
of outstanding shares.

     As of the date hereof, the Offshore Fund directly beneficially owns
7,598,200 shares of Common Stock, representing 6.5% of the outstanding shares of
Common Stock. None of the other individual Funds owns a number of shares of
Common Stock representing more than 5% of such total.

     As of the date hereof, Mr. Aryeh beneficially owns 1,011 shares of Common
Stock, which represent less than 0.001% of the outstanding shares of Common
Stock.

     (b) The Management Company and Mr. Loeb share voting and dispositive power
over the 11,300,000 shares of Common Stock held by the Funds. The Management
Company, Mr. Loeb and the Offshore Fund share voting power and dispositive power
over the 7,598,200 shares of Common Stock held by the Offshore Fund. Mr. Aryeh
has sole voting power and dispositive power over the 1,011 shares of Common
Stock held by JALAA.

     (c) Schedule A hereto sets forth certain information with respect to
transactions by the Funds (at the direction of the Management Company and Mr.
Loeb) in the Common Stock since the most recent filing on Schedule 13D. Schedule
B hereto sets forth certain information with respect to transactions by the
Offshore Fund (at the direction of the Management Company and Mr. Loeb) in the
Common Stock since the most recent filing on Schedule 13D. Schedule C sets forth
certain information with respect to transactions by Mr. Aryeh in the Common
Stock since the most recent filing on Schedule 13D.

     All of the transactions set forth on Schedules A, B and C were effected in
open market transactions in the NASDAQ Global Select Market. Except as set forth
on Schedules A, B and C since the most recent filing on Schedule 13D there were
no transactions in the Common Stock effected by any of the Management Company,
Mr. Loeb, the Offshore Fund or Mr. Aryeh, nor, in the case of the Management
Company and the Offshore Fund and to the best of their knowledge, any of their
directors, executive officers, general partners or members.
