ITEM  2.02.  RESULTS  OF  OPERATIONS  AND  FINANCIAL  CONDITION.

As discussed in Item 4.02, the previously issued financial statements of The GSI
Group,  Inc. (the "Company") for the years ended December 31, 2003 and 2002 (and
the  quarterly  periods  included  therein) should not be relied upon because of
errors  believed  by  management  of  the  Company  to  exist in those financial
statements  and  management's  belief  that  a  restatement  of  those financial
statements  is  likely.

ITEM  4.02.  NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED
AUDIT  REPORT  OR  COMPLETED  INTERIM  REVIEW.

As  of  the  date of this Current Report on Form 8-K, the Board of Directors and
Chief  Executive  Officer  of  the  Company  have  become  aware  of information
indicating  possible  errors  in  previously  issued  financial  statements  and
commenced  a  review  of  certain  of  the  Company's  accounting  policies  and
practices,  including  among  other  things  accounting  policies  and practices
relating  to  workers'  compensation  accrual,  inventory,  compensation expense
related  to  employee  stock  purchases  and  executive  compensation.

Based  on  the preliminary results of its ongoing review, as of the date of this
Current  Report  on  Form 8-K, the Company, in consultation with its independent
auditors,  BKD,  LLP,  has  determined  that  its  previously  issued  financial
statements  for  the  years  ended  December  31,  2003,  2002 and 2001 (and the
quarterly  periods  included  therein)  contain  certain errors and that certain
adjustments  may be required to correct such errors.  Accordingly, the financial
statements referred to in the preceding sentence should not be relied upon until
such  time  as  the  Company  is  able  to quantify such errors and assess those
matters  as  to  which  a  restatement  of  its  financial statements is needed.

As  the  Company  and BKD, LLP have not yet completed their analyses of all such
matters, the Company is currently unable to determine the amount of any required
adjustments  or the periods affected by such errors with certainty.  The Company
(in  consultation  with  BKD,  LLP)  will  attempt  to  conclude  these analyses
promptly.  At  the  conclusion of its analyses, the Company will determine those
matters  as to which a restatement of its financial statements is needed for the
periods  referenced  above,  although  management  of the Company believes it is
likely  that  a  restatement  will  be  needed.
