                      THE GSI GROUP, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.     SUMMARY  OF  SIGNIFICANT  ACCOUNTING  POLICIES

          The  financial  statements  have  been prepared by The GSI Group, Inc.
(the  "Company"),  without  audit,  pursuant to the rules and regulations of the
Securities  and  Exchange  Commission.  Certain  information  and  footnote
disclosures  normally  included  in  financial statements prepared in accordance
with  accounting  principles  generally accepted in the United States of America
have  been condensed or omitted pursuant to such rules and regulations, although
the  Company  believes that the disclosures are adequate to make the information
not  misleading.  These  financial statements should be read in conjunction with
the  financial  statements and related notes contained in the Company's December
31,  2004 Form 10-K as filed with the Securities and Exchange Commission.  Other
than  as  indicated herein, there have been no significant changes from the data
presented  in  the  Company's  2004  Form  10-K.

     In  the  opinion  of  management,  the  financial  statements  contain  all
adjustments necessary to present fairly the financial position of the Company as
of  April  1,  2005  and  the results of operations and cash flows for the three
months  ended April 1, 2005.  Those adjustments consist only of normal recurring
adjustments.

     The  results  of  operations for the three-month period ended April 1, 2005
are  not  necessarily  indicative  of  the  operating results for the full year.

2.    RESTATEMENT

     During  the Company's 2004 year-end closing process, the Company discovered
unintentional  accounting  errors  in  prior  years'  financial statements.  The
errors  were  corrected  in the 2004 financial statements.  A description of the
errors  and related impact of each on the financial statements follows.  Amounts
are  stated  in  thousands  of  dollars.

     At  the  end  of  2001,  the Company began the process of shutting down its
Mason City, Iowa plant, which served as the headquarters for its DMC subsidiary.
As  the  Company  began the revenue cycle process at its corporate headquarters,
cost  of  sales  estimates  were  understated during 2002, while cost accounting
records  were  being  developed for the products previously handled by the Mason
City  employees,  which  caused  the  remaining  inherited inventory costs to be
overstated  by  approximately  $6,470.  The  Company  became  aware  of  the
overstatement  in  early  2003, but erroneously assigned the overstated value to
inventory  that  would  flow  through the cost of sales over the next few years.
This  erroneous  correction  reduced  the  stated  value  of  the  inventory  by
approximately  $2,206  in  2003  and  $4,264  in  2004. During the 2004 year-end
closing  process, this issue was re-examined, and the Company determined that it
would  be  appropriate to restate the 2002 cost of sales and year-end inventory,
the  period  when  the  overstatement  occurred.  This  adjustment increased the
previously  reported  2004  quarterly  net  income  by  $360.

     In 1997, the Company's majority stockholder began selling non-voting shares
to  certain  employees.  The  Company's majority stockholder helped finance each
employee's  purchase  with  a  loan to each employee with the shares as the only
collateral  for  the notes.  APB Opinion 25 and its interpretations require that
these  transactions  be  imputed  to  the  Company's financial statements and be
accounted  for  as  variable  stock  awards,  which practice the Company had not
previously  followed.  Treatment  of  the  transaction as a variable stock award
requires  the  Company  to recognize as compensation expense the extent to which
the  fair  market  value  of the underlying shares exceeds the original purchase
price  for  such  shares. The fair value of the underlying shares first exceeded
the  price  paid  for the shares in 2002.  The effect of recording the resulting
compensation  expense  reduced  previously reported 2004 quarterly net income by
$448.  There  were  no  dividends paid to the non-voting stockholders during the
first  fiscal  quarter  of  2004.

     In  2002,  the  Company  entered  into an agreement with the manager of its
Brazilian  subsidiary  whereby  the  Company  agreed  to issue him shares of the
Brazilian subsidiary's stock primarily based on the financial performance of the
Brazilian  subsidiary.  This  agreement  constitutes  a  stock  compensation
arrangement  for  which  the  Company  did not previously recognize compensation
expense.  The  effect  of  recording  compensation  expense  related  to  this
arrangement  reduced  previously  reported  2004  quarterly  net income by $125.
                                        7

     Prior to the 2004 closing process, the Company had been using Mexican Pesos
as  the  functional currency of its Mexican subsidiary.  During the 2004 closing
process,  the  Company  determined  that  the correct functional currency of its
Mexican subsidiary should be U.S. Dollars rather than Mexican Pesos.  The effect
of  this  change  reduced  previously  reported 2004 quarterly net income by $6.

     The Company changed from a stop-loss workers' compensation insurance policy
to a high-deductible self-insured policy in 2000 and did not subsequently accrue
a  liability  for  claims incurred but not reported.  The effect of accruing for
such  claims  in  2004  reduced previously reported quarterly net income by $55.

     The  Company also made adjustments in 2004 to correct previous reporting of
overhead  adjustments  in  overseas inventories and gain on inter-company sales.

     The  impact  of  the  above  noted  adjustments  on the Company's financial
statements  for  the  first  fiscal  quarter  of 2004 is summarized in the table
below.  Amounts  are  stated  in  thousands of dollars except for per share line
items.

5.   SUPPLEMENTAL  CASH  FLOW  INFORMATION

     The  Company  paid approximately $0.5 million in interest during the fiscal
quarters  ended  April  1,  2005  and April 2, 2004.  The Company paid no income
taxes during the first quarters of 2005 and 2004 because it was a subchapter "S"
corporation  during  those  periods.

6.     LONG-TERM  DEBT

     The  indenture  governing  the Company's senior subordinated notes contains
certain restrictive covenants.  The more significant of these covenants restrict
the  ability of the Company to dispose of assets, incur additional indebtedness,
pay  dividends  or make distributions and other payments affecting subsidiaries.
The Company was in compliance with the covenants under the indenture as of April
1,  2005.  The  Company  issued a call for redemption of its senior subordinated
notes  due  2007  on  May  16,  2005.  See  Note  9,  "Subsequent  Events."

     The  credit  facility  with  Congress  Financial Corporation (Central) (the
"Credit  Facility")  required  the  Company  to maintain a senior debt to EBITDA
ratio  and  a fixed charge coverage ratio.  Borrowings under the Credit Facility
were secured by substantially all of the assets of the Company.  The Company had
$21.1 million of availability under the revolving portion of the Credit Facility
as of April 1, 2005.  The Company was in compliance with the covenants under the
Credit  Facility  as  of April 1, 2005.  On May 16, 2005, the Company refinanced
the  Credit  Facility  and  entered  into a new loan and security agreement with
Wachovia  Capital  Finance  Corporation  (Central).  See  Note  9,  "Subsequent
Events."

7.     COMMITMENTS  AND  CONTINGENCIES

     Sales  of  agricultural  equipment are seasonal, with farmers traditionally
purchasing  grain  storage  bins  and grain drying and handling equipment in the
summer and fall in conjunction with the harvesting season, and swine and poultry
producers  purchasing equipment during prime construction periods in the spring,
summer  and  fall.  The  Company's  sales  and net income have historically been
lower  during the first and fourth fiscal quarters as compared to the second and
third  quarters.

8.   BUSINESS  SEGMENT

     The  Company  has  no  separately  reportable  segments  in accordance with
Statement  of  Financial Accounting Standard ("SFAS") No. 131, "Disclosure About
Segments  of  an Enterprise and Related Information."  Under the enterprise wide
disclosure  requirements  of SFAS 131, the Company reports sales by each product
line.  Amounts  for  the  first fiscal quarters of 2005 and 2004 are as shown in
the  table  below  (in  thousands).

     For  the  first fiscal quarters of 2005 and 2004, sales in Brazil were $8.6
million  and  $7.3 million, respectively.  Long-lived assets in Brazil were $4.4
million  at  April  1,  2005.

9.     SUBSEQUENT  EVENTS

     On  May  16,  2005, the Company completed the offering of $110.0 million in
aggregate principal amount of its 12% senior notes due 2013.  In connection with
this  offering,  the Company also refinanced its senior secured credit facility,
which  new facility includes a $60.0 million revolving credit facility.  Also on
this  date,  the closing of the acquisition of all of the issued and outstanding
shares  of  the  Company's  common  stock  by  GSI  Holdings  Corp.  took place.
                                        9
<PAGE>
     The  proceeds  from  the notes offering, together with borrowings under the
Company's  refinanced  credit  facility  and a cash equity contribution from GSI
Holdings  Corp.,  will  be  used to redeem all of the Company's outstanding 10 %
senior  subordinated  notes  due  2007  as  well  as  pay the related redemption
premium,  repay  all  outstanding borrowings under the Company's previous credit
facility, repay all outstanding loans made to the Company by its former majority
stockholder  and  pay fees and expenses related to the refinancing transactions.

     The Company may redeem all or part of the new senior notes beginning on May
15,  2009  at the redemption prices specified in the indenture governing the new
notes.  Prior to May 15, 2008, the Company may redeem up to 35% of the new notes
at  a  redemption price of 112% of the principal amount, plus accrued and unpaid
interest,  if  any,  to the date of the redemption, with the proceeds of certain
equity  offerings.

ITEM  2.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND
        RESULTS  OF  OPERATIONS.

     The  following  discussion  of  the  financial  condition  and  results  of
operations  of  the  Company should be read in conjunction with the Consolidated
Financial  Statements  and  the  notes  included  in  Item  1  hereof.

GENERAL

     The  Company  is  a major worldwide manufacturer of agricultural equipment.
The  Company's  grain,  swine  and  poultry  products  are used by producers and
purchasers  of  grain,  and  by  producers  of swine and poultry. Demand for our
agricultural  equipment  is  driven  by  the  overall  level of grain, swine and
poultry  production,  the  level  of  net  farm income, agricultural real estate
values  and  producers'  increasing  focus  on  improving  productivity in their
operations. In addition, fluctuations in grain and feed prices affect our sales,
with  sustained  increases  in  grain  and feed prices increasing demand for our
grain  equipment  and  decreasing demand for our swine and poultry equipment. We
believe  that  our  diversified  product  offerings  mitigate  the  effects  of
fluctuations in the price of grain. Sales of our swine and poultry equipment are
also  affected  by long-term trends in consumer demand for pork and poultry both
domestically  and  internationally.

     Sales  of  agricultural  equipment are seasonal, with farmers traditionally
purchasing  grain  storage bins and grain conditioning and handling equipment in
the  summer  and  fall  in conjunction with the harvesting season, and swine and
poultry  producers purchasing equipment during prime construction periods in the
spring,  summer  and  fall. The Company's sales, operating income and net income
have  historically  been  lower  during  the first and fourth fiscal quarters as
compared  to  the  second and third quarters. Traditionally, this has caused the
Company  to  have  increased  working  capital needs during the second and third
quarters  as  material  is purchased and converted to inventory during the year.

     Although  the Company's sales are primarily denominated in U.S. dollars and
are  not  generally  affected  by currency fluctuations (except for transactions
from  the  Company's  Brazilian operation), the production costs, profit margins
and  competitive  position  are  affected  by  the  strength  of the U.S. dollar
relative  to  the strength of the currencies in countries where its products are
sold.

     The Company's international sales have historically comprised a significant
portion  of  our total sales. In the first fiscal quarters of 2005 and 2004, the
Company's  international  sales  accounted  for  28%  and  31%  of  total sales,
respectively.  International  operations  generally are subject to various risks
that  are  not  present  in  domestic  operations,  including  restrictions  on
dividends,  restrictions on repatriation of funds, unexpected changes in tariffs
and  other  trade  barriers,  difficulties  in  staffing  and  managing  foreign
operations,  political  instability,  fluctuations  in  currency exchange rates,
reduced  protection for intellectual property rights in some countries, seasonal
reductions in business activity and potentially adverse tax consequences, any of
which  could  adversely  impact  our  international  operations.

     The  primary raw materials we use to manufacture our products are steel and
polymers.  Fluctuations  in the prices of steel and, to a lesser extent, polymer
materials  can  impact  our  cost  of  sales.

     On  May  16, 2005, in connection with the closing of the purchase of all of
the  issued and outstanding shares of the Company's common stock by GSI Holdings
Corp.,  the  Company  was  converted  from  a  subchapter  "S"  corporation to a
subchapter "C" corporation, which means that it will now be a taxable entity for
federal  and state income tax purposes.  For the portion of the Company's fiscal
year  preceding  that  date,  the  Company  has  made  a tax distribution to its
stockholders in an amount sufficient to allow them to pay their resulting income
taxes  for  such  period.

RESTATEMENT


     During  the Company's 2004 year-end closing process, the Company discovered
unintentional  accounting  errors  in  prior  years'  financial statements.  The
errors  were  corrected  in the 2004 financial statements.  A description of the
errors  and related impact of each on the financial statements follows.  Amounts
are  stated  in  thousands  of  dollars.
                                       11

     At  the  end  of  2001,  the Company began the process of shutting down its
Mason City, Iowa plant, which served as the headquarters for its DMC subsidiary.
As  the  Company  began the revenue cycle process at its corporate headquarters,
cost  of  sales  estimates  were  understated during 2002, while cost accounting
records  were  being  developed for the products previously handled by the Mason
City  employees,  which  caused  the  remaining  inherited inventory costs to be
overstated  by  approximately  $6,470.  The  Company  became  aware  of  the
overstatement  in  early  2003, but erroneously assigned the overstated value to
inventory  that  would  flow  through the cost of sales over the next few years.
This  erroneous  correction  reduced  the  stated  value  of  the  inventory  by
approximately  $2,206  in  2003  and  $4,264  in  2004. During the 2004 year-end
closing  process, this issue was re-examined, and the Company determined that it
would  be  appropriate to restate the 2002 cost of sales and year-end inventory,
the  period  when  the  overstatement  occurred.  This  adjustment increased the
previously  reported  2004  quarterly  net  income  by  $360.

     In 1997, the Company's majority stockholder began selling non-voting shares
to  certain  employees.  The  Company's majority stockholder helped finance each
employee's  purchase  with  a  loan to each employee with the shares as the only
collateral  for  the notes.  APB Opinion 25 and its interpretations require that
these  transactions  be  imputed  to  the  Company's financial statements and be
accounted  for  as  variable  stock  awards,  which practice the Company had not
previously  followed.  Treatment  of  the  transaction as a variable stock award
requires  the  Company  to recognize as compensation expense the extent to which
the  fair  market  value  of the underlying shares exceeds the original purchase
price  for  such  shares. The fair value of the underlying shares first exceeded
the  price  paid  for the shares in 2002.  The effect of recording the resulting
compensation  expense  reduced  previously reported 2004 quarterly net income by
$448.  There  were  no  dividends paid to the non-voting stockholders during the
first  fiscal  quarter  of  2004.

     In  2002,  the  Company  entered  into an agreement with the manager of its
Brazilian  subsidiary  whereby  the  Company  agreed  to issue him shares of the
Brazilian subsidiary's stock primarily based on the financial performance of the
Brazilian  subsidiary.  This  agreement  constitutes  a  stock  compensation
arrangement  for  which  the  Company  did not previously recognize compensation
expense.  The  effect  of  recording  compensation  expense  related  to  this
arrangement  reduced  previously  reported  2004  quarterly  net income by $125.

     Prior to the 2004 closing process, the Company had been using Mexican Pesos
as  the  functional currency of its Mexican subsidiary.  During the 2004 closing
process,  the  Company  determined  that  the correct functional currency of its
Mexican subsidiary should be U.S. Dollars rather than Mexican Pesos.  The effect
of  this  change  reduced  previously  reported 2004 quarterly net income by $6.

     The Company changed from a stop-loss workers' compensation insurance policy
to a high-deductible self-insured policy in 2000 and did not subsequently accrue
a  liability  for  claims incurred but not reported.  The effect of accruing for
such  claims  in  2004  reduced previously reported quarterly net income by $55.

     The  Company also made adjustments in 2004 to correct previous reporting of
overhead  adjustments  in  overseas inventories and gain on inter-company sales.

     The  impact  of  the  above noted adjustments on the Company's first fiscal
quarter  of 2004 financial statements is summarized in the table below.  Amounts
are  stated  in  thousands  of  dollars  except  for  per  share  line  items.

RESULTS  OF  OPERATIONS

Three  Months  Ended  April 1, 2005 Compared to Three Months Ended April 2, 2004

     Sales  increased  24.4%  or  $14.3  million  to  $72.7 million in the first
quarter  of  2005 compared to $58.4 million in the first quarter of 2004.  Grain
sales  increased  32%  in the first quarter 2005 to $42.9 million primarily as a
result  of  strong  grain  storage  demand  and  market share penetration of new
products  such  as  grain  transportation  equipment.   Strong  sales  of  grain
equipment  in  our Brazilian subsidiary also contributed to the increase.  Swine
sales  increased  29.6%  due  to an improved swine production market that allows
producers  to  upgrade equipment.  Poultry equipment sales were essentially flat
year  over  year.

     Gross  profit  increased  to  $17.9 million in the first quarter of 2005 or
24.7%  of sales from $11.7 million or 20.1% of sales in the same period of 2004.
This  increase  was primarily due to increased volume, which allowed the company
to  leverage  its  fixed  expenses.

     Operating  expenses  increased  2.9% or $0.2 million to $9.1 million in the
first  quarter  of  2005  from  $8.9  million  in  the same period of 2004. This
increase  was  primarily the result of increased selling expenses related to the
increased  volume.

     Operating  income  increased  to  $8.9 million in the first quarter of 2005
from  $2.9  million  in  the  first  quarter  of 2004.  Operating income margins
increased  to  12.4%  of  sales  in  2005  from  5.0%  in  2004.

     Interest  expense  increased  $0.5  million in the first quarter of 2005 as
compared  to  the  first  quarter  of  2004  due  to  higher  borrowing  costs.

     Net  loss  decreased  $5.7  million to income of $5.2 million for the first
quarter  of  2005  from  a  loss  of  $0.5  million  in the same period of 2004.

LIQUIDITY  AND  CAPITAL  RESOURCES

     The  Company  has historically funded capital expenditures, working capital
requirements,  debt  service,  stockholder  dividends and stock repurchases from
cash  flow from its operations, augmented by borrowings made under the Company's
credit  facility  and  the  sale  of  the  Company's  notes.

     The Company's working capital requirements for its operations are seasonal,
with  investments  in working capital typically building in the second and third
quarters  and  then  declining  in  the  first and fourth quarters.  The Company
defines working capital as current assets less current liabilities.  As of April
1,  2005,  the  Company had $45.0 million of working capital, a decrease of $0.3
million  from  working capital as of December 31, 2004.  The decrease in working
capital  was  primarily  due  to  increases in payroll related expenses, accrued
expenses, accrued interest, customer deposits and accounts payable and decreases
in  prepaids  of  $8.8  million,  partially  offset  by  increases  in  accounts
receivable  and  inventory  of  $7.9  million.

     Operating activities provided $7.1 million and $6.4 million in cash flow in
the  first  quarters of 2005 and 2004, respectively.  This $0.7 million increase
in cash flow was primarily the result of an increase in net income, depreciation
and  amortization,  inventory,  deferred  taxes and other current assets of $7.6
million, partially offset by a decrease in accounts receivable, accounts payable
and  customer  deposits  of  $6.7 million compared to the first quarter of 2004.

     Investing activities used $1.1 million and $0.3 million in cash flow in the
first  quarters of 2005 and 2004, respectively.  The cash was used primarily for
machinery  and  equipment  purchases.

     Financing activities used $6.3 million and $7.1 million in cash flow in the
first  quarters of 2005 and 2004, respectively.  The cash was used primarily for
payments  on  the  Company's  credit  facility.

     The  Company  believes  that  existing  cash, cash flow from operations and
available  borrowings  under  its  refinanced  revolving credit facility will be
sufficient to support its working capital, capital expenditures and debt service
requirements  for  the  foreseeable  future.
                                       13
<PAGE>
     On  May 16, 2005, the Company entered into a five-year credit facility with
lenders led by Wachovia Capital Finance Corporation (Central) to provide up to a
maximum  amount  of  $60.0  million,  subject  to  various  conditions including
borrowing base availability to replace the Company's then-existing senior credit
facility,  which  provided  for maximum outstanding borrowings of $75.0 million.
Up  to  $15.0 million of the facility will be available for issuances of letters
of  credit.  The availability of revolving loans and letters of credit are based
on  a  borrowing  base,  which includes accounts receivable, inventory and fixed
assets.  In  addition,  subject  to  the  fulfillment  of  certain  conditions,
including  the  consent  of  the  Export-Import Bank of the United States ("Exim
Bank")  and  any changes that me be required to our exiting agreements with Exim
Bank,  we  expect  to  be  able  to borrow revolving loans and obtain letters of
credit  of  up  to $2.5 million based on the value of certain foreign subsidiary
accounts  receivable  and inventory under the Exim Bank working capital guaranty
program.  Revolving loan borrowings bear interest at a rate per annum as elected
by  the Company equal to 1.5% to 2.0% over LIBOR or 0.0% to 0.50% over the Prime
Rate,  both  being  based  on  excess  availability  under  the  borrowing base.

INFLATION

     The  Company  believes  that inflation has not had a material effect on its
results  of  operations  or  financial  condition  during  recent  periods.

CRITICAL  ACCOUNTING  POLICIES

     There  have  been  no  material changes to the critical accounting policies
since  December  31,  2004.

ITEM  3.  QUANTITATIVE  AND  QUALITATIVE  DISCLOSURES  ABOUT  MARKET  RISK

     The  Company  is  subject to market risk associated with adverse changes in
interest  rates  and foreign currency exchange rates.  The Company does not hold
any  market  risk sensitive instruments for trading purposes.  At April 1, 2005,
principal exposed to interest rate risk was limited to $35.8 million in variable
rate  debt.  The  interest rates on the Company's various debt instruments range
from  4.5% to 12.25%.  The Company measures its interest rate risk by estimating
the  net  amount  by  which  potential  future net earnings would be impacted by
hypothetical  changes  in  market  interest  rates  related to all interest rate
sensitive  assets  and  liabilities.  A 1% change in interest rates would have a
$0.4  million  impact  on  the  Company's  results  of  operations.

     At  April  1,  2005,  approximately  13.8%  of  sales  were  derived  from
international  operations  with exposure to foreign currency exchange rate risk.
The  Company  mitigates  its  foreign currency exchange rate risk principally by
establishing  local  production  facilities  in  the  markets  it  serves and by
invoicing  customers  in  the  same currency as the source of the products.  The
Company  also  monitors  its  foreign  currency  exposure  in  each  country and
implements  strategies  to  respond  to  changing  economic  and  political
environments.  The  Company's  exposure  to  foreign currency exchange rate risk
relates primarily to the financial position and the results of operations of its
Brazilian  and  South  African  subsidiaries.  The  Company's  exposure  to such
exchange rate risk as it relates to the Company's financial position and results
of  operations  would  be  adversely  impacted  by  further  devaluation  of the
Brazilian  Real  per  U.S.  dollar  and  the South African Rand per U.S. dollar.
These  amounts  are  difficult to accurately estimate due to factors such as the
inherent  fluctuation  of inter-company account balances, balance sheet accounts
and  the  existing  economic  uncertainty  and future economic conditions in the
international  marketplace.


ITEM  4.  CONTROLS  AND  PROCEDURES

OVERVIEW

     In  connection  with  the preparation of its Annual Report on Form 10-K for
the  fiscal  year  ended  December 31, 2004, the Company's management identified
material weaknesses in the Company's internal controls over financial reporting.
As  defined  by  the  Public  Company  Accounting  Oversight  Board ("PCAOB") in
Auditing  Standard  No.  2,  a material weakness is a significant deficiency, or
combination  of  significant  deficiencies,  that  results in more than a remote
likelihood  that  a  material  misstatement  of  the annual or interim financial
statements  will  not  be  prevented  or  detected.

     The  identified material weaknesses in the Company's internal controls over
financial reporting have resulted in insufficient controls relating to inventory
accounting,  the  treatment  of  foreign  currency  matters,  accounting matters
relating  to  differences  between  U.S.  and  foreign accounting principles and
practices,  accounting  for  non-operating expenses, the accounting treatment of
purchases  and  sales of the Company's debt securities, executive salary accrual
methodology,  the identification and treatment of relevant workers' compensation
reserves  and  minority  interest  reserves  and  the  treatment  of stock based
compensation expense issues. These weaknesses have resulted in adjustments being
recorded  in  the  Company's  financial  statements for the first fiscal quarter
ended  April  2,  2004.  The  Company's  management  has  discussed the material
weaknesses  with its independent registered public accounting firm, BKD LLP. BKD
LLP  issued  a  "material  weakness" letter in connection with its review of the
Company's  financial  statements  for  the  fiscal year ended December 31, 2004.

DISCLOSURE  CONTROLS  AND  PROCEDURES

     The  Company maintains disclosure controls and procedures that are designed
to  ensure  that information required to be disclosed in the reports it files or
submits  under  the  Securities  Exchange  Act of 1934, as amended, is recorded,
processed,  summarized  and  reported,  within the time periods specified in the
SEC's rules and forms, and that such information is accumulated and communicated
to  our  management,  including  the  Company's Chief Executive Officer and Vice
President  of  Finance,  as  appropriate,  to  allow  timely decisions regarding
disclosure.  The  Company's  management,  with  the  participation  of its Chief
Executive  Officer and Vice President of Finance, has performed an evaluation of
the Company's disclosure controls and procedures as of April 1, 2005, the end of
the  period  covered  by  this  Quarterly  Report  on  Form  10-Q. Based on that
evaluation,  which  included  an  review  of  the  matters  discussed above, the
Company's  Chief  Executive Officer and Vice President of Finance concluded that
the  Company's  disclosure  controls and procedures were not effective as of the
end  of  the  period  covered  by  this  Quarterly  Report  on  Form  10-Q.
                                       15
<PAGE>
CHANGES  IN  INTERNAL  CONTROLS

     The Company's management believes that substantial remediation measures are
required  in  order  to  improve  the  Company's  internal controls. The Company
believes  that  the  material  weaknesses identified above resulted in part from
inadequate  staffing  and  training  within the Company's finance and accounting
group,  and  the  Company  believes that the process of preparing this Quarterly
Report on Form 10-Q and the related review of the Company's financial statements
for  the first fiscal quarter ended April 1, 2005 have resulted in a significant
improvement  in  the  finance  and  accounting  staff's  familiarity  with  the
accounting and financial treatment of the issues identified above. The Company's
management  is  in  the  process  of reviewing whether additional accounting and
financial  management  staff  should  be  retained,  and  intends  to review the
question  of  whether  it  should  utilize  additional,  or  different,  outside
resources.  At  the  same  time  as the Company continues its efforts to improve
internal  control  over  financial  reporting  and  disclosure  controls  and
procedures,  management  has  implemented  additional procedures and controls to
mitigate  recognized  deficiencies  specifically  for  the  preparation  of this
Quarterly  Report.  Management  believes  that  these  additional  controls  and
procedures,  when  combined  with the Company's existing disclosure controls and
procedures  and  internal  control  over  financial reporting, were effective in
ensuring  the  proper collection, evaluation and disclosure of the financial and
other  information  included  in  this  report and that the financial statements
included  in  this  report  are  fairly  stated  in  all  material  respects.

     There  are  no legal proceedings pending against the Company, which, in the
opinion  of  management,  would  have a material adverse affect on the Company's
business,  financial  position  or  results  of  operations.

                                 CERTIFICATIONS

a)  Designed  such disclosure controls and procedures, or caused such disclosure
controls  and  procedures  to  be designed under our supervision, to ensure that

subsidiaries,  is made known to us by others within those entities, particularly
during  the  period  in  which  this  report  is  being  prepared;

b)  Designed  such  internal  control  over  financial reporting, or caused such

d) Disclosed in this report any change in the registrant's internal control over
financial  reporting  that  occurred  during the registrant's most recent fiscal

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  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.
