I, H. C. Allen, Jr., Chief Financial Officer of Dorchester Minerals Management
GP LLC, General Partner of Dorchester Minerals Management LP, General Partner
of Dorchester Minerals, L.P., (the "Registrant"), certify that:

1.   I have reviewed this quarterly report on Form 10-Q of Dorchester Minerals,
     L.P.;

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 report, fairly present in all material
     respects the financial condition, results of operations and cash flows of
     the Registrant as of, and for, the periods presented in this report;

4.   The  Registrant'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)) and internal control over
     financial reporting (as defined in Exchange Act Rules 13a-15(f) and
     15d-15(f)) for the Registrant and 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 the
          Registrant, including its consolidated subsidiaries, is made known to
          us by others within those entities, particularly during the period in
          which this report is being prepared;

     b)   Designed  such  internal  control over  financial  reporting,  or
          caused such internal control over financial reporting to be
          designed under our supervision, to provide reasonable assurance
          regarding the reliability of financial reporting and the
          preparation of financial statements for external purposes in
          accordance with generally accepted accounting principles.

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

     d)   Disclosed in this report any change in the Registrant's
          internal control over financial reporting that occurred
          during the Registrant's most recent fiscal quarter that
          has materially affected, or is reasonably likely to
          materially affect, the Registrant's internal control
          over financial reporting; and

5.   The Registrant's  other  certifying  officer and I have disclosed, based
     on our most recent evaluation of internal control over financial reporting,
     to the Registrant's auditors and the audit committee of the Registrant's
     board of directors (or persons performing the equivalent functions):

      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 the Registrant'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 the Registrant's internal
          control over financial reporting.
