                                  CERTIFICATION

I, Brian McDougall, certify that:

    1.   I have reviewed this quarterly report on Form 10-Q of Liquidmetal
         Technologies, Inc.;

    2.   Based on my knowledge, this report does not contain any untrue
         statement of a material fact or omit 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(s) 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 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) Evaluated the effectiveness of the registrant'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 the registrant's
     internal control over financial reporting that occurred during the
     registrant's most recent fiscal quarter (the registrant's fourth fiscal
     quarter in the case of an annual report) 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(s) and I have disclosed,
         based on our most recent evaluation of internal control over financial
         reporting, to the registrant's auditor's 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.
