Item 5.03 Amendments to Articles of  Incorporation  or Bylaws;  Change in Fiscal
Year.

As of March 1, 2005,  the Board of  Directors  (the  "Board") of  Maverick  Tube
Corporation  (the  "Company")  adopted Amended and Restated Bylaws (the "Amended
and Restated  Bylaws"),  which Amended and Restated  Bylaws are effective as of
January 1, 2005.

The Board initially contemplated amending the Company's bylaws in recognition of
certain  corporate  officer changes which occurred in connection with the recent
announcements  appointing  C.  Robert  Bunch as  Chairman of the Board and Chief
Executive  Officer,   James  A.  Cowan  as  President,   Pamela  Boone  as  Vice
President-Treasurer,  and various other changes in executive  officer  duties in
connection  with the  reorganization  of the business along business unit lines.
Following its review of the  then-current  bylaws,  the Board determined that it
was in the  Company's  best  interest  to fully  amend and  restate  the bylaws.

Descriptions  of the  provisions  adopted  and/or  changed by amendment  and the
respective  previous  provisions,  if applicable,  are included  below.

* In the Amended and Restated  Bylaws,  the  description  of the Chairman of the
Board position is included in "Directors"  section (Article III), rather than in
the  "Officers"  section  (Article  IV), and the  description  has been expanded
(Article III,  Section 16). The Amended and Restated  Bylaws provide that unless
the Board of Directors, by resolution, designates otherwise, the Chairman of the
Board position is not an officer  position  (Article III, Section 16). The prior
position description was also deleted (Article IV, former Section 6).

* The maximum  number of directors  has been reduced from 15 to 12 (Article III,
Section  1). The minimum  number of  directors  (five)  remains  unchanged.  The
Amended and Restated  Bylaws provide that the actual number of directors will be
fixed by the Board of  Directors  from time to time  (Article  III,  Section 1),
rather than being included in the bylaws.

* The statement that "directors need not be stockholders"  (Article III, Section
1) has been deleted.

* Consistent with Delaware law and the Company's practice,  an express statement
indicating that directors are elected by plurality vote has been included in the
Amended and Restated Bylaws (Article II, Section 4).

* The Amended and Restated  Bylaws  provide that notices to Board  members,  and
waivers of notice by Board  members,  may be sent  electronically  (Article  VI,
Sections 7 and 8).  Prior to adoption of the Amended and  Restated  Bylaws,  the
bylaws did not provide for such notices or waivers of notice.

* Consistent with the Company's current  management  structure,  the Amended and
Restated Bylaws provide for a CEO position,  and differentiate between the roles
of the CEO and the President (various sections;  duties described in Article IV,
Section 6).

* The descriptions of the Vice Chairman  position (Article IV, former Section 7)
and the Treasurer  position (Article IV, former Section 12) have been deleted in
the Amended and Restated Bylaws.  Although the Amended and Restated Bylaws allow
for both positions,  elimination of the  descriptions  more accurately  reflects
current management structure.

* The Amended and Restated  Bylaws provide that the annual  stockholder  meeting
will be held  on a date  as  determined  by the  Board.  The  bylaws  previously
provided  that  the  annual  meeting  would  be held on "the  third  Tuesday  in
February" (Article II, Section 2).

* The Amended and  Restated  Bylaws  clarify  that voting via the  internet  and
telephone is  permissible  (Article II,  Section 5), and that  delivery of proxy
materials via the internet and e-mail is permissible (Article II, Section 7).

* The Amended and Restated  Bylaws  allow the Board to appoint one  inspector of
election,  rather than mandating multiple  inspectors,  as the bylaws previously
provided (Article II, Section 11).

* The  Amended  and  Restated  Bylaws  indicate  that the  statutorily  required
stockholder list is to be maintained at the corporate  offices for 10 days prior
to the annual meeting, as opposed to the annual meeting site, as provided in the
prior bylaws (Article II, Section 9).

* The indemnification  section (Article III, former Section 16) has been removed
in  the  Amended  and  Restated  Bylaws.  This  provision  is  included  in  the
certificate of incorporation, and it is unnecessary to repeat it in the bylaws.

* The reference to the Company's fiscal year (Article VI, Section 5) was updated
to reflect  its  current  12/31 year end.  Although  the fiscal year was changed
previously and the change was publicly disclosed, the bylaws were not previously
updated to reflect the change.

In  addition,  the  document  has been  revised to be  gender-neutral,  and some
typographical errors have been corrected.

The  Amended  and  Restated  Bylaws  are  attached  hereto  as  Exhibit  3.1 and
incorporated herein by reference.
