                                  CERTIFICATION

I, Gregg Eisenberg, Chairman of the Board, President and Chief Executive Officer
of Maverick Tube Corporation ("Maverick"), certify that:

1.       I have reviewed this annual report on Form 10-K of Maverick;

2.       Based on my knowledge, this report does not contain any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in light of the circumstances under which
         such statements were made, not misleading with respect to the period
         covered by this report;

3.       Based on my knowledge, the financial statements, and other financial
         information included in this annual report, fairly present in all
         material respects the financial condition, results of operations and
         cash flows of Maverick as of, and for, the periods presented in this
         report;

4.       Maverick's other certifying officer and I are responsible for
         establishing and maintaining disclosure controls and procedures (as
         defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for Maverick and
         we have:

         a) designed such disclosure controls and procedures, or caused such
         disclosure controls and procedures to be designed under our
         supervision, to ensure that material information relating to Maverick,
         including its consolidated subsidiaries, is made known to us by others
         within those entities, particularly during the period in which this
         annual report is being prepared;

         b) evaluated the effectiveness of Maverick's disclosure controls and
         procedures and presented in this report our conclusions about the
         effectiveness of the disclosure controls and procedures, as of the end
         of the period covered by this report based on such evaluation; and

         c) disclosed in this report any change in Maverick's internal control
         over financial reporting that occurred during Maverick's most recent
         fiscal quarter that has materially affected or is reasonably likely to
         materially affect Maverick's internal control over financial reporting;
         and

5.       Maverick's other certifying officer and I have disclosed, based on our
         most recent evaluation of internal control over financial reporting, to
         Maverick's auditors and the audit committee of Maverick's board of
         directors:

         a) all significant deficiencies and material weaknesses in the design
         or operation of internal control over financial reporting which are
         reasonably likely to adversely affect Maverick's ability to record,
         process, summarize and report financial information; and

         b) any fraud, whether or not material, that involves management or
         other employees who have a significant role in Maverick's internal
         controls over financial reporting; and
