     I, Michael L. Hirschey state and attest that:

     (1) I am the President of OneSource Technologies, Inc. (the "issuer").

     (2)  Accompanying  this  certification  is the Form 10-KSB/A for the annual
period ended December 31, 2002, a periodic report (the "periodic  report") filed
by the issuer with the Securities  Exchange Commission pursuant to Section 13(a)
or 15(d) of the  Securities  Exchange Act of 1934 (the  "Exchange  Act"),  which
contains financial statements.

     (3) I hereby certify,  pursuant to Exchange Act Rules 13a-14 and 15d-14, as
adopted  pursuant to Section  302 (a) of the  Sarbanes-Oxley  Act of 2002,  that
based on my knowledge:

          a) I have reviewed the report;

          b) based on my  knowledge,  the  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 the report;

          c)  based  on  my  knowledge,  the  financial  statements,  and  other
     financial  information  included  in  the  report,  fairly  present  in all
     material respects the financial  condition,  results of operations and cash
     flows of the issuer as of, and for, the periods presented in the report;

     (4) I and the other certifying officer:

          a.  are  responsible  for  establishing  and  maintaining  "disclosure
     controls and  procedures" (a  newly-defined  term reflecting the concept of
     controls and procedures related to disclosure embodied in Section 302(a)(4)
     of the Act) for the issuer;

          b. have designed  such  disclosure  controls and  procedures to ensure
     that material  information is made known to them,  particularly  during the
     period in which the periodic report is being prepared;

          c.  have  evaluated  the  effectiveness  of  the  issuer's  disclosure
     controls  and  procedures  as of a date  within 90 days prior to the filing
     date of the report;

          d. and have  presented  in the  report  their  conclusions  about  the
     effectiveness  of the  disclosure  controls  and  procedures  based  on the
     required evaluation as of that date;

     (5) I and the other  certifying  officer  have  disclosed  to the  issuer's
auditors and to the audit committee of the board of directors:

          a. all significant deficiencies in the design or operation of internal
     controls (a  pre-existing  term  relating to  internal  controls  regarding
     financial  reporting)  which could adversely affect the issuer's ability to
     record,  process,  summarize and report  financial data and have identified
     for the issuer's auditors any material weaknesses in internal controls;

<PAGE>

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

     6) I and the other certifying  officer have indicated in the 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
their  evaluation,  including any corrective  actions with regard to significant
deficiencies and material weaknesses.
