I, David A. Conway, certify, pursuant to 18 U.S.C. Section 1350, as adopted
pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, that:

1.  I have reviewed this annual report of WaterChef, Inc. on Form 10-KSB/A for
    the period ended December 31, 2002;

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 to
    make the statements made, in light of the circumstances under which the
    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.  As the registrant's certifying officer I am responsible for establishing and
    maintaining disclosure controls and procedures (as defined in Exchange Act
    Rules 13a-14 and 15d-14 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, and

    (b) evaluated the effectiveness of the registrant's disclosure controls and
        procedures as of a date within 90 days prior to the filing date of 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.  As the registrant's certifying officer I have disclosed, based on our most
    recent evaluation, to the registrant's auditors and the audit committee of
    registrant's board of directors (or persons performing the equivalent
    functions):

    (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

6.  As the registrant's certifying officer I have indicated in this annual
    Report whether or not there were any 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.
