     This Amendment No. 5 amends the Schedule 13D filed on November 20, 2006 (as
amended by Amendment No. 1 thereto filed on December 1, 2006, Amendment No. 2
thereto filed on February 5, 2007, Amendment No. 3 thereto filed on February 16,
2007, Amendment No. 4 thereto filed on February 23, 2007 and this Amendment No.
5, the "Schedule 13D") and is being 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 (the
"Offshore Fund"), Daniel S. Loeb, an individual ("Mr. Loeb", and together with
the Offshore Fund and the Management Company, the "Reporting Persons"). This
Amendment No. 5 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 the 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 March 12, 2007, the Management Company, the Offshore Fund and certain
other Funds (collectively, the "Third Point Entities") entered into a
stockholders agreement (the "Stockholders Agreement") with the Company pursuant
to which the Third Point Entities will be provided representation on the
Company's Board of Directors (the "Board") no later than March 15, 2007. Under
the Stockholders Agreement, the Board will increase its size by two and elect
Mr. Loeb and Bradley L. Radoff (the "Third Point Designees") to fill the newly
created directorships. Each of the Third Point Designees will be a member of the
Management Committee of the Board, which is comprised of the members of the
Board who are not officers of the Company, and Mr. Loeb will be appointed to the
Executive Committee and Mr. Radoff to both the Compensation Committee and the
Nominating & Corporate Governance Committee of the Board.

     One of the Third Point Designees will be a member of the class of directors
whose terms expire at the Company's annual meeting of stockholders to be held on
May 15, 2007 (the "2007 Annual Meeting"). The Stockholders Agreement provides
that the Board will nominate, recommend and solicit proxies in respect of the
Third Point Designee who becomes a member of this class and who will stand for
re-election at the 2007 Annual Meeting. The other Third Point Designee will
become a member of the class of directors whose terms expire in 2008.
Additionally, because the Company thought it appropriate to add a representative
of another

                                       5


substantial stockholder, on or prior to the twentieth day after the
2007 Annual Meeting the Board will be entitled to create a third new
directorship and offer to appoint a representative of TRT Holdings, Inc. (the
"TRT Designee") to fill such directorship. If the TRT Designee accepts such
offer and is appointed, the TRT Designee would be a member of the class of
directors whose terms expire at the Company's annual meeting of stockholders in
2009. The Stockholders Agreement also provides that if a special committee of
the Board is formed in connection with the exploration of strategic
alternatives, the Board will cause the Third Point Designees to be appointed to
serve on such committee.

     Pursuant to the Stockholders Agreement, the Third Point Entities have
agreed (the "Standstill Provisions") that until December 31, 2007 (the
"Standstill Termination Date") they will not: (i) engage in any solicitation of
proxies or communicate any voting decision pursuant to Rule 14a-1(l)(2)(iv),
(ii) submit any proposal at any annual or special meeting of the stockholders of
the Company, (iii) otherwise engage in any conduct with the purpose of causing
Company stockholders to vote contrary to the recommendation of the Board, (iv)
enter into any discussions, arrangements or understandings with any person other
than the Company with respect to any of the foregoing or announce any plan
or proposal to take any action with respect to any of the foregoing, (v) act,
alone or with others, to seek to control or influence the management or Board of
the Company or (vi) enter into any discussions, arrangements or understandings
with any person other than the Company with respect to seeking to control or
influence the management or Board of the Company. Such restrictions with respect
to control or influence over management or the Board do not apply, however, to
actions taken by a Third Point Designee, while serving as a member of the Board,
in his capacity as such.

     In addition, until the Standstill Termination Date, the Third Point
Entities have agreed to be present at each meeting of stockholders of the
Company held for the purpose of electing any member of the Board and to vote (i)
for the director nominees recommended by the Board and (ii) in accordance with
the recommendation of the Board on any proposals of any other stockholder of the
Company who is also proposing one or more nominees for election as director in
opposition to the Board. The Third Point Entities have also agreed that they
will no longer be entitled to representation on the Board, and that the Third
Point Designees will resign, immediately following the Resignation Date. The
"Resignation Date" will occur upon the earliest of (i) a violation of the
Standstill Provisions described above, (ii) the sale or transfer of Company
voting securities by the Third Point Entities and certain related persons such
that their aggregate beneficial ownership of such securities is reduced to less
than five percent (calculated in accordance with Rule 13d-3(d)(1)(i) under the
Securities Exchange Act of 1934, as amended), (iii) the first date after the
Standstill Termination Date that any Third Point entity or any of their

                                       6


affiliates engages in any activity that was prohibited by the Standstill
Provisions prior to such Standstill Termination Date, and (iv) the date of
termination of the Stockholders Agreement.

     Under the Stockholders Agreement, if a Third Point Designee becomes unable
to serve on the Board as the result of death or disability or resigns because
the Third Point Designee is no longer employed or affiliated with any of the
Third Point Entities, the Third Point Entities are entitled to nominate a
replacement. In the event that, prior to the tenth day preceding the Company's
annual meeting of stockholders in 2008 (the "2008 Annual Meeting"), a Third
Point Designee resigns other than as a result of the events described in the
preceding sentence, the Third Point Entities are entitled to nominate a
replacement to fill such vacancy a single time for each Third Point Designee
directorship (a maximum of two such instances). Each replacement nominee must be
reviewed and approved by the Nominating & Corporate Governance Committee of the
Board before being elected to the Board (such recommendation and election not to
be unreasonably withheld or delayed).

     The Company is restricted by the Stockholders Agreement from, prior to the
2008 Annual Meeting, adopting any amendment to the bylaws of the Company (the
"Bylaws") that would (i) affect the ability of the stockholders to amend the
Bylaws, (ii) change the advance notice provisions of the Bylaws or (iii)
prescribe any qualifications for directors. The Company also agrees that it will
not, prior to the 2008 Annual Meeting, create any additional directorship,
except those provided for in the Stockholders Agreement and any directorship
that has a term ending at the 2008 Annual Meeting, or propose any amendment to
the Certificate of Incorporation of the Company.

     Pursuant to the Stockholders Agreement, if the TRT Designee does not accept
the offer to be appointed to the Board, such directorship will remain unfilled
and the Company will take such action as necessary to keep the size of the Board
at 10 directors until the 2008 Annual Meeting. If the TRT Designee accepts the
offer and, prior to the 2008 Annual Meeting, is unable to serve due to death or
disability or resigns from the Board, the Board will not appoint any person to
fill such vacancy and will reduce the number of directorships by one and take
any other action to keep the size of the Board at 10 directors until the 2008
Annual Meeting.

     The Company has agreed to reimburse the Management Company and its
affiliates for all out-of-pocket costs and expenses incurred by them related to
(a) the preparation and filing of any proxy materials by the Management Company
and its affiliates, (b) the preparation for and the solicitation of proxies for
the 2007 Annual Meeting, including without limitation legal fees and the fees of
the proxy solicitor retained for such meeting, or (c) the efforts of the
Management Company and its affiliates to cause the Company to explore and pursue
certain strategic alternatives. The reimbursement of expenses is subject to a
cap of $200,000 in the aggregate.

                                       7
