                 SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002



I, Claire M. Iacobucci, certify that:

1.  I have reviewed this annual report on Form 10-K of Nestor, Inc.;

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 such 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.  The  registrant's  other  certifying  officer  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 annual 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 and I have disclosed,  based on our
most recent  evaluation of internal  control over  financial  reporting,  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 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  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 over financial reporting.
