    this annual report on Form 10-K of Qualstar Corporation;

    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

    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

| | (a) Designed such disclosure controls and
    procedures, or caused such disclosure controls and procedures to

    those entities, particularly during the period in which this
    report is being prepared;

|
| | (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 (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



| |

    registrants other certifying officer(s) and I have

    of directors (or persons performing the equivalent functions):



| |

    involves management or other employees who have a significant
    role in the registrants internal control over financial
