                               CERTIFICATION

I, Jerry I. Jacobson, certify that:

      1. I have reviewed this quarterly report on Form 10-QSB of Jacobson
         Resonance Enterprises, Inc.;

      2. Based on my knowledge, this quarterly 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 quarterly report;

      3. Based on my knowledge, the financial statements, and other financial
         information included in this quarterly 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 quarterly report;

      4. The registrant's other certifying officers and I are responsible for
         establishing and maintaining disclosure controls and procedures
         (as defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant
         and we 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 quarterly report is being
         prepared;

     (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
         quarterly report (the "Evaluation Date"); and

     (c) presented in this quarterly 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 officers and 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 function):

     (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 officers and I have indicated in this
         quarterly report whether or not 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.

                                  /s/ Jerry I. Jacobson
August 18, 2003                       Jerry I. Jacobson, Chief Executive Officer
