      I, Wayne Thaw, Chief Executive Officer and Chief Financial Officer of the
Registrant, certify that:

1.    I have reviewed this annual report on Form 10-K of TNR Technical, Inc.;

2.    Based on my knowledge, this annual report does not contain any untrue
      statement of a material fact or omit to state a material fact necessary in
      order 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 annual 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
      the registrant as of, and for, the periods presented in this annual
      report;

4.    The registrant's other certifying officer and I are responsible for
      establishing and maintaining "disclosure controls and procedures" for the
      registrant and have:

      a)    designed such disclosure controls and procedures 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 annual
            report is being prepared;

      b)    evaluated the effectiveness of the registrant's disclosure controls
            and procedures as of the end of the period covered by this annual
            report (the "Evaluation Date"); and

      c)    presented in this annual report our conclusions about the
            effectiveness of the disclosure controls and procedures based on our
            evaluation as of the Evaluation Date.

5.    The registrant's other certifying officer and I have disclosed, based on
      our most recent evaluation, to the registrant's auditors and the audit
      committee of the registrant's board of directors:

      a)    all significant deficiencies in the design or operation of internal
            controls which could adversely affect the registrant's ability to
            record, process, summarize and report financial data and have
            identified for the registrant's auditors any material weaknesses in
            internal controls; and

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

6.    The registrant's other certifying officer and I have indicated in this
      annual report whether there were significant changes in internal controls
      or in other factors that could significantly affect internal controls
      subsequent to the date of our most recent evaluation, including any
      corrective actions with regard to significant deficiencies and material
      weaknesses.
