I, William W.R. Elder, certify that:


     1.   I  have  reviewed  this  quarterly report on Form 10-Q of Genus, Inc.;

     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(s) 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  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(s) 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 the
          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  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  control  over  financial  reporting.
