I, Simon K. Hodson, certify that:

1. I have reviewed this quarterly report on Form 10-Q of EarthShell Corporation;

2. Based on my 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 the period covered by this report;

3. Based  on  my  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  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 we
   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
        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 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 function):

     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 information; 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.
