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

     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

       in this quarterly 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  quarterly  report  is   being
          prepared;

          b)  Evaluated  the  effectiveness of  the  registrant's
          disclosure  controls and procedures  and  presented  in

          effectiveness of the disclosure controls and procedures
          as  of  the end of the period covered by this quarterly
          report based on such evaluation; and

          c) Disclosed in this quarterly 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;

     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):
<Page>2 (Continued)
                  a)  All significant deficiencies in the design
               and   material  weaknesses  in  the   design   or
               operation  of  internal controls  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.
