     This Amendment No. 4 to Schedule 13D ("Amendment No. 4") is filed on behalf
of Third Point LLC, a Delaware limited liability company (the "Management
Company"), Third Point Offshore Fund, Ltd., a Cayman Islands limited liability
exempted company ("Offshore Fund"), and Daniel S. Loeb, an individual ("Mr.
Loeb", and together with the Management Company and Offshore Fund, the
"Reporting Persons"), and amends the Schedule 13D filed on November 20, 2006
(the "Original 13D", and together with Amendment No. 1 thereto previously filed
on December 1, 2006, Amendment No. 2 thereto previously filed on February 5,
2007, Amendment No. 3 thereto previously filed on February 16, 2007, and this
Amendment No. 4, the "Schedule 13D"). This Amendment No. 4 relates to the common
stock, par value $1.00 per share (the "Common Stock"), of Pogo Producing
Company, 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, collectively, including but not limited to Offshore
Fund, the "Funds"). The Funds directly own the Common Stock to which this
Schedule 13D relates, and the Reporting Persons 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.


Item 4.   Purpose of Transaction

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

     On February 23, 2007, Offshore Fund delivered to the Company the notice
(the "Notice") required under the Company's bylaws (the "Bylaws") of proposals
in order to permit the shareholders of the Company to elect a majority of the
Company's board of directors (the "Board") at the Company's 2007 annual meeting
of shareholders scheduled for May 15, 2007(the "Annual Meeting"). In addition,
Offshore Fund proposed six nominees for election at the Annual Meeting. Pursuant
to the Notice, Offshore Fund notified the Company of the following five
proposals:

     Proposal #1: Offshore Fund proposes to nominate George K. Hickox, Jr.,
Christian Woessner, III, and Benjamin W. Miller for election at the Annual
Meeting as directors of the Company for terms expiring in 2010, to replace the
Company's three directors whose terms expire at the Annual Meeting.

     Proposal #2: Offshore Fund proposes to amend the Bylaws to set the number
of members of the Board at eleven.

     Proposal #3: Offshore Fund proposes to amend the Bylaws to provide the
Company's shareholders with the right to fill vacancies and newly created
directorships on the Board, and to grant the shareholders the exclusive right to
fill any such directorships created by action of the shareholders.

                                        5


     Proposal #4: Offshore Fund proposes to nominate Elizabeth K. Blake, George
W. Braly and Robert T. Hanley for election at the Annual Meeting to fill the
newly created directorships on the Board, subject to the approval of Proposals
#2 and #3.

     Proposal #5: Offshore Fund proposes to amend the Bylaws to permit that the
Chairman of the Board will be appointed by the Board and will not automatically
be the Chief Executive Officer, as currently provided in the Bylaws.

     Accordingly, if Proposals #2, 3 and 4 are adopted, the Board will be
expanded by three seats and the shareholders will have the ability to fill such
newly created seats at the Annual Meeting. With the successful adoption of
Proposal #1 as well, a majority of the Board would be elected by the
shareholders at the Annual Meeting. The Reporting Persons intend to solicit
proxies for use at the Annual Meeting in order to seek adoption of the proposals
described above, allowing for the election to the Board of Offshore Fund's
nominees, who would constitute a majority of the Board if elected.

                                      * * *
