                      CERTIFICATION OF
                   CHIEF EXECUTIVE OFFICER


  I, Alvaro Cadena, certify that:

     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 financial condition, results of
       operations and cash  flows of  the  registrant as of,
       and for, the periods  presented 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  this  quarterly
               report  our conclusions  about  the  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  (the registrant's
               fourth 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;

2
     5.The  registrant's  other certifying  officer  and  I
       have disclosed,  based  on our most recent
       evaluation  of  the 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 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.
