                     ESCO TECHNOLOGIES INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.   BASIS OF PRESENTATION

     The  accompanying  consolidated  financial  statements,  in the  opinion of
     management,  include all  adjustments,  consisting only of normal recurring
     accruals,  necessary for a fair presentation of the results for the interim
     periods presented.  The consolidated  financial statements are presented in
     accordance  with the  requirements  of Form  10-Q and  consequently  do not
     include all the  disclosures  required by accounting  principles  generally
     accepted in the United States of America  (GAAP).  For further  information
     refer to the consolidated  financial  statements and related notes included
     in the  Company's  Annual  Report on Form 10-K for the  fiscal  year  ended
     September 30, 2004.

     The results for the three and  six-month  periods  ended March 31, 2005 are
     not necessarily indicative of the results for the entire 2005 fiscal year.


2.   DISCONTINUED OPERATIONS - 2004

     Microfiltration   and  Separations   Businesses   (MicroSep)  The  MicroSep
     businesses  consisted of PTI Advanced  Filtration  Inc.,  PTI  Technologies
     Limited, and PTI S.p.A.  Effective April 2, 2004, the Company completed the
     sale  of  PTI  Advanced  Filtration  Inc.  (Oxnard,   California)  and  PTI
     Technologies  Limited (Sheffield,  England) to domnick hunter group plc for
     $18 million in cash. On June 8, 2004, the Company completed the sale of PTI
     S.p.A. (Milan, Italy) to a group of investors comprised of the subsidiary's
     senior  management for $5.3 million.  An after-tax loss of $2.2 million and
     $2.6  million  related  to the  MicroSep  businesses  is  reflected  in the
     Company's  fiscal 2004 results from  discontinued  operations for the three
     and six-month periods ended March 31, 2004, respectively.


3.   EARNINGS PER SHARE (EPS)

     Basic EPS is calculated  using the weighted average number of common shares
     outstanding during the period. Diluted EPS is calculated using the weighted
     average number of common shares  outstanding  during the period plus shares
     issuable  upon the assumed  exercise of dilutive  common share  options and
     vesting of performance-accelerated restricted shares (restricted shares) by
     using  the  treasury  stock  method.  The  number  of  shares  used  in the
     calculation  of earnings per share for each period  presented is as follows
     (in thousands):

     Options to purchase  1,500  shares of common stock at a price of $77.71 and
     options to purchase  104,050  shares of common stock at prices ranging from
     $45.36 - $48.58 were outstanding  during the six-month  periods ended March
     31, 2005 and 2004,  respectively,  but were not included in the computation
     of diluted EPS because the options'  exercise  prices were greater than the
     average  market price of the common  shares.  The options expire at various
     periods through 2013.  Approximately  24,000 and 16,000  restricted  shares
     were excluded from the respective computation of diluted EPS based upon the
     application  of the treasury stock method for the three month periods ended
     March 31, 2005 and 2004, respectively.






     Had  compensation  cost for the Company's stock option plans and restricted
     share plans been  determined  based on the fair value at the grant date for
     awards  outstanding  during the three and six-month periods ended March 31,

     assumptions used for grants in the three and six-month  periods ended March
     31,  2005 and 2004,  respectively:  expected  dividend  yield of 0% in both

8.   RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     In December 2004, the Financial  Accounting  Standards  Board (FASB) issued
     SFAS No. 123 (R),  "Share-Based Payment" (SFAS No. 123 (R)). This Statement
     replaces  SFAS No.  123, "Accounting  for  Stock-Based  Compensation"  and
     supersedes APB No. 25,"Accounting for Stock Issued to Employees." SFAS 123
     (R) requires all stock-based compensation to be recognized as an expense in
     the financial  statements  and that such cost be measured  according to the
     fair value of stock  options.  SFAS 123 (R) will be effective for the first
     annual period beginning after June 15, 2005. The Company plans to adopt the
     provisions  of this  Statement  in the first  quarter  of fiscal  2006 on a
     prospective basis. The Company currently provides the pro forma disclosures
     required  by SFAS No.  148, "Accounting  for  Stock-Based  Compensation-
     Transition and  Disclosure,"  on a quarterly  basis (see "Note 3 - Earnings
     Per Share").

     In  December   2004,  the  FASB  issued  FASB  Staff  Position  FAS  109-2,
     "Accounting and Disclosure  Guidance for the Foreign Earnings  Repatriation
     Provision  within the American  Jobs Creation Act of 2004 (FSP 109-2)." The
     American  Jobs  Creation  Act of 2004,  (the "Act")  provides for a special
     one-time  deduction of 85 percent of certain foreign  earnings  repatriated
     into the U.S. from non-U.S.  subsidiaries  through  September 30, 2006. The
     Company is currently  evaluating the merits of repatriating funds under the
     Act. The range of reasonably  possible amounts of unremitted  earnings that
     are being  considered for  repatriation  is between zero and $29.4 million,
     which would require the Company to pay income taxes in the range of zero to
     $2.1  million.  Federal  income taxes on the  repatriated  amounts would be
     based on the 5.25%  effective  statutory  rate as provided in the Act, plus
     applicable  withholding  taxes.  To date,  the Company has not provided for
     income taxes on  unremitted  earnings  generated  by non-U.S.  subsidiaries
     given the Company's  historical intent to permanently invest these earnings
     abroad.  As a result,  additional  taxes may be required to be recorded for
     any funds  repatriated  under the Act. The Company  expects to complete its
     evaluation of the repatriation provision of the Act by September 30, 2006.

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

RESULTS OF OPERATIONS

The  following  discussion  refers  to the  Company's  results  from  continuing
operations,  except where noted. The Microfiltration and Separations  businesses
(MicroSep),  which were sold in the third quarter of fiscal 2004,  are accounted
for as discontinued  operations in accordance with SFAS No. 144, "Accounting for
the  Impairment or Disposal of  Long-Lived  Assets."  Accordingly,  the MicroSep
businesses are reflected as discontinued  operations in the financial statements
and related notes for fiscal 2004.

NET SALES
Net sales increased $4.0 million (3.9%) to $106.2 million for the second quarter
of fiscal 2005 from $102.2  million for the second  quarter of fiscal 2004.  Net
sales  increased $11.9 million (6.0%) to $210.5 million for the first six months
of fiscal 2005 from $198.6  million for the first six months of fiscal 2004. The
sales increase for the second quarter of fiscal 2005 and in the first six months
of fiscal  2005 as  compared to the prior year  periods is  primarily  due to an
increase in sales within the Communications segment.

- -Filtration/Fluid Flow
Net sales  decreased $1.2 million (2.8%) to $41.0 million for the second quarter
of fiscal 2005 from $42.2  million for the second  quarter of fiscal  2004.  Net
sales increased $2.9 million (3.5%) to $85.0 million for the first six months of
fiscal  2005 from $82.1  million  for the first six months of fiscal  2004.  The
sales decrease during the fiscal quarter ended March 31, 2005 as compared to the
prior year quarter is mainly due to the  following:  lower defense  shipments at
VACCO of $1.1 million;  a net sales decrease at Filtertek of $0.9 million driven
by lower  automotive  shipments;  partially  offset  by  higher  commercial  and
military aerospace shipments at PTI of $0.8 million.  The sales increase for the
first six months of fiscal  2005 as  compared to the prior year period is mainly
due to an increase in shipments of commercial and military aerospace products at
PTI of $3.0 million.

- -Communications
For the second  quarter of fiscal  2005,  net sales of $36.1  million  were $5.7
million,  or 18.8%  higher than the $30.4  million of net sales  recorded in the
second  quarter  of fiscal  2004.  Net sales of $69.6  million  in the first six
months of fiscal 2005 were $7.8 million,  or 12.6% higher than the $61.8 million
recorded  in the first six  months of fiscal  2004.  The sales  increase  in the
second  quarter of fiscal  2005 as  compared  to the prior  year  period was the
result of higher  shipments of Comtrak's  SecurVision  video security  products
(which  represented  $3.1 million of the sales increase) and higher shipments of
automatic  meter reading  (AMR)  equipment to the electric  utility  cooperative
(COOP) market and other customers  (which  represented $2.6 million of the sales
increase).  The  increase  in sales in the  first six  months of fiscal  2005 as
compared to the prior year period was the result  higher  shipments of Comtrak's
video security  products,  which contributed $9.7 million to the sales increase,
partially  offset  by a  decrease  in sales of AMR  equipment  of $1.9  million.
Comtrak's  sales  were $3.5  million  for the second  quarter of fiscal  2005 as
compared to $0.4 million for the prior year second quarter and $10.6 million for
the first six months of fiscal 2005 as  compared  to $0.9  million for the prior
year six-month period.

The decrease in sales of AMR  equipment  for the first six months of fiscal 2005
as compared to the prior year period is due to the wind-down of the PPL Electric
Utilities  Corporation  (PPL) contract.  Sales to PPL were $0.4 million and $7.4
million in the fiscal quarters ended March 31, 2005 and 2004, respectively,  and
$1.4 million and $19.9  million in the first six months of fiscal 2005 and 2004,
respectively.  The decrease in sales to PPL was  partially  offset by higher AMR
product sales to the COOP market and other customers. DCSI's sales to COOP's and
other  customers  were $32.2  million and $22.5  million in the fiscal  quarters
ended March 31, 2005 and 2004,  respectively,  and were $57.6  million and $41.0
million for the first six months of fiscal 2005 and 2004, respectively.

- -Test
Net sales  decreased $0.5 million (1.7%) to $29.1 million for the second quarter
of fiscal 2005 from $29.6  million for the second  quarter of fiscal  2004.  Net
sales increased $1.2 million (2.2%) to $55.9 million for the first six months of
fiscal  2005 from $54.7  million  for the first six months of fiscal  2004.  The
sales decrease during the fiscal quarter ended March 31, 2005 as compared to the
prior  year  quarter is mainly  due to a  decrease  in sales from the  Company's
European  operations of approximately  $3.7 million due to the completion of two
large test chamber  projects.  This decrease was partially offset by an increase
in sales from the  Company's  U.S.  operations  of  approximately  $2.0  million
(driven by the increase of government shielding projects),  an increase in sales
from the  Company's  Asian  operations  of  approximately  $1.3  million  and an
increase in sales of antennas and other  components.  The sales increase for the
first six months of fiscal  2005 as  compared to the prior year period is mainly
due to additional test chamber  installations,  component  sales, and government
shielding projects.

ORDERS AND BACKLOG
Backlog was $253.9  million at March 31, 2005  compared  with $249.1  million at
September 30, 2004. The Company  received new orders  totaling $215.4 million in
the first six months of fiscal 2005.  New orders of $99.8  million were received
in the  first six  months  of  fiscal  2005  related  to  Filtration/Fluid  Flow
products,  $62.7 million  related to  Communications  products  (includes  $55.7
million of new orders  related to AMR  products),  and $53.0 million  related to
Test  products.  The new orders  received in the  Filtration/Fluid  Flow segment
include  a  $15.9  million  multi-year  order  for  quiet  valves  and  manifold
assemblies used on the Virginia Class Submarine.

GROSS PROFIT
The Company  computes  gross  profit as net sales less cost of sales.  The gross
profit  margin  is the  gross  profit  divided  by  net  sales,  expressed  as a
percentage. The gross profit margin was 35.0% and 30.7% in the second quarter of
fiscal 2005 and 2004, respectively.  The gross profit margin was 34.7% and 31.0%
for the first six months of fiscal 2005 and 2004, respectively.  The increase in
gross  profit  margins  in the second  quarter of fiscal  2005 and the first six
months of fiscal  2005 was mainly  due to higher  margins  on  shipments  in the
Communications  segment due to the favorable sales mix of AMR products resulting
from additional sales to the COOP market, and additional  shipments of Comtrak's
products.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
Selling,  general and  administrative  (SG&A) expenses for the second quarter of
fiscal 2005 were $21.3 million (20.0% of net sales), compared with $19.1 million
(18.7% of net  sales)  for the prior  year  period.  For the first six months of
fiscal 2005, SG&A expenses were $41.1 million (19.5% of net sales) compared with
$37.9  million  (19.1% of net sales) for the prior year period.  The increase in
SG&A  spending in the fiscal  quarter  ended March 31, 2005 and in the first six
months of fiscal 2005 as compared to the respective prior year periods is due to
increased  personnel  costs  ($2.1  million  and  $2.8  million,   respectively)
associated with marketing, project management and new product development within
the  Communications  segment to further  penetrate  the investor  owned  utility
market.

OTHER (INCOME) EXPENSES, NET
Other  (income)  expenses,  net, were $(0.2) million for the quarter ended March
31, 2005  compared to $0.5 million for the prior year  quarter.  Other  (income)
expenses,  net,  were  $(0.7)  million  for the first six months of fiscal  2005
compared to $1.1  million for the prior year  period.  Principal  components  of
other (income)  expenses,  net, for the first six months of fiscal 2005 included
$1.2 million of royalty income  partially offset by $0.5 million of amortization
expense of  identifiable  intangible  assets  (primarily  patents,  licenses and
software).  Principal components of other (income) expenses,  net, for the first
six months of fiscal 2004  included  $0.9  million of exit costs  related to the
Filtertek  Puerto Rico facility and $0.5 million of amortization of identifiable
intangible assets (primarily patents, licenses and software).

EBIT
The Company  evaluates the performance of its operating  segments based on EBIT,
defined  below.  EBIT was $16.1  million  (15.2% of net  sales)  for the  second
quarter  of fiscal  2005 and $11.8  million  (11.5% of net sales) for the second
quarter of fiscal 2004. For the first six months of fiscal 2005,  EBIT was $32.6
million  (15.5% of net  sales)  and $22.5  million  (11.3% of net sales) for the
first six months of fiscal  2004.  EBIT for the first six months of fiscal  2004
was  negatively  impacted by $1.3 million of severance and exit costs related to
the Filtertek Puerto Rico facility (Filtration/Fluid Flow segment).

This Form 10-Q contains the financial measure"EBIT", which is not calculated in
accordance with generally accepted accounting principles in the United States of
America  (GAAP).  EBIT provides  investors and  Management  with an  alternative
method for assessing the Company's operating results. The Company defines "EBIT"
as earnings from continuing  operations  before  interest and taxes.  Management
evaluates the  performance of its operating  segments based on EBIT and believes
that EBIT is useful to investors to demonstrate the operational profitability of
the  Company's  business  segments by excluding  interest  and taxes,  which are
generally  accounted for across the entire Company on a consolidated basis. EBIT
is also one of the measures  Management uses to determine  resource  allocations
within the Company and incentive compensation.  The following table represents a
reconciliation of EBIT to net earnings from continuing operations.

- -Filtration/Fluid Flow
EBIT was $5.0 million (12.3% of net sales) and $4.2 million (10.0% of net sales)
in the second quarters of fiscal 2005 and 2004, respectively,  and $12.1 million
(14.2%  of net  sales)  and $7.7  million  (9.4% of net  sales) in the first six
months of fiscal 2005 and 2004,  respectively.  For the second quarter of fiscal
2005 as compared to the prior year quarter,  EBIT  increased $0.8 million due to
the following:  a $1.0 million  increase at Filtertek due to improved  operating
efficiencies, which included $0.3 million of cost reimbursement mentioned below,
and royalty income from license  agreements;  a $0.6 million increase at PTI due
to higher aerospace sales;  partially offset by a $0.8 million decrease at VACCO
due to lower  defense  shipments.  For the  first six  months of fiscal  2005 as
compared  to the prior year  period,  EBIT  increased  $4.4  million  due to the
following: a $2.8 million increase at Filtertek,  which included $0.9 million of
cost reimbursement from a medical device customer related to a shortfall between
its actual purchases  versus the minimum  contractually  guaranteed  amount (the
first six months of fiscal 2004  included  $1.3 million of exit costs related to
the Puerto  Rico  facility);  and a $1.6  million  increase at PTI due to higher
shipments of aerospace products.

- -Communications
EBIT in the second quarter of fiscal 2005 was $10.6 million (29.5% of net sales)
as compared to $7.2 million  (23.9% of net sales) in the prior year period.  For
the first six months of fiscal 2005, EBIT was $20.3 million (29.1% of net sales)
as compared to $14.6 million (23.7% of net sales) in the prior year period.  The
increase  in EBIT in the  second  quarter  of  fiscal  2005 and in the first six
months of fiscal 2005 as compared to the prior year periods is mainly due to the
additional  shipments of Comtrak's products,  as well as the favorable sales mix
of AMR products  resulting from  additional  sales to the COOP market,  and cost
reductions  realized on certain AMR components.  The Company expects to continue
to increase its  engineering  and new product  development  expenditures  in the
Communications  segment in order to continue its growth in the AMR markets,  and
to further differentiate its technology from the competition.

- -Test
EBIT in the second  quarter of fiscal 2005 was $3.3 million (11.5% of net sales)
as compared to $3.3 million  (11.1% of net sales) in the prior year period.  For
the first six months of fiscal 2005,  EBIT was $5.4 million  (9.7% of net sales)
as compared to $5.5 million  (10.0% of net sales) in the prior year  period.  In
the second  quarter of fiscal  2005,  EBIT margin was higher than the prior year
period  due  primarily  to the  favorable  changes in sales mix  resulting  from
additional sales of antennas and other  components.  The decrease in EBIT margin
in the first six months of fiscal  2005 as  compared to the prior year period is
mainly  the  result of  installation  cost  overruns  incurred  during the first
quarter of fiscal 2005 on certain government  shielding projects being installed
in challenging  areas  throughout the world, as well as increased costs of steel
and copper.

- -Corporate
Corporate  costs included in EBIT were $(2.9) million and $(5.1) million for the
three and  six-month  periods  ended March 31, 2005,  respectively,  compared to
$(2.9) million and $(5.2) million for the respective prior year periods.

INTEREST INCOME, NET
Interest  income,  net,  was $0.3  million  and $0.8  million  for the three and
six-month  periods  ended  March 31,  2005,  respectively,  compared to interest
income of $0.5 million for both respective  prior year periods.  The decrease in
interest  income in the second  quarter of fiscal  2005 as compared to the prior
year quarter is due to $0.3 million of interest  received on the  collection  of
the Riverhead note  receivable in February 2004. The increase in interest income
in the first six months of fiscal 2005 as compared to the respective  prior year
period is due to higher  average cash  balances on hand in fiscal 2005 and a tax
refund of lookback interest.



INCOME TAX EXPENSE
The second quarter  fiscal 2005 effective  income tax rate was 36.6% compared to
38.2% in the second quarter of fiscal 2004. The effective income tax rate in the
first six months of fiscal  2005 was 37.3%  compared  to 38.5% in the prior year
period. The decrease in the effective income tax rate in the first six months of
fiscal 2005 is primarily due to the timing and volume of profit contributions of
the Company's foreign operations. The Company estimates the annual effective tax
rate for fiscal 2005 to be approximately 37.5%.

CAPITAL RESOURCES AND LIQUIDITY
Working  capital  increased  to $169.1  million  at March 31,  2005 from  $165.2
million at September 30, 2004.  During the first six months of fiscal 2005, cash
increased  $2.3 million,  net of the $24.9 million  share  repurchase.  Accounts
receivable  decreased by $5.1 million in the first six months of fiscal 2005, of
which $4.0 million represented collections from two significant customers (PREPA
and  Boeing).  Inventories  increased by $5.2 million in the first six months of
fiscal 2005, of which $3.2 million related to the Test segment due to the timing
of sales and $1.3 million was to build  safety  stock within the  Communications
segment due to a change in suppliers. In addition,  accounts payable and accrued
expenses  decreased  by $7.0  million  in the  first six  months of fiscal  2005
primarily due to the timing of vendor payments.

Net cash provided by operating  activities from continuing  operations increased
$4.8 million to $29.1  million in the first six months of fiscal 2005,  compared
to $24.3 million in the same period of fiscal 2004.

During the second  quarter of fiscal  2005,  Filtertek  signed an  agreement  to
license  certain of its patents  related to  needle-free  connectors  to a third
party for $1.5 million in cash and  recognized  $0.2  million of royalty  income
related to this transaction,  after deducting $0.2 million of professional fees.
The unrealized gain of $1.1 million will be recognized on a straight-line  basis
over the remaining patent life, through 2011.

Capital  expenditures  for  continuing  operations  were $4.6  million  and $4.8
million in the first six  months of fiscal  2005 and 2004,  respectively.  Major
expenditures in the current period included manufacturing equipment and facility
modifications used in the Filtration/Fluid Flow businesses.

At March 31, 2005, the Company has approximately  $7.0 million in commitments in
the Communications  segment to further differentiate its products and to further
penetrate the investor owned utility market. This amount is expected to be spent
during fiscal 2005.

The closure and  relocation of the Filtertek  Puerto Rico facility was completed
in March 2004. The Puerto Rico facility is included in other current assets with
a carrying value of $3.6 million at March 31, 2005. The facility continues to be
actively marketed for sale.

In October 2004, the Company entered into a new $100 million five-year revolving
bank credit  facility with a $50 million  increase  option,  which  replaced its
then-existing credit facility.  At March 31, 2005, the Company had approximately
$98.6 million available to borrow under the credit facility in addition to $74.6
million cash on hand.  Against the $100 million  available  under the  revolving
credit facility at March 31, 2005, the Company had outstanding letters of credit
of $1.4 million.  Cash flow from  operations and borrowings  under the Company's
bank credit facility are expected to meet the Company's capital requirements and
operational needs for the foreseeable future.

STOCK REPURCHASE PROGRAM
In August 2004, the Company's  Board of Directors  approved the extension of the
previously  authorized  (February 2001) open market repurchase  program of up to
1.1 million shares,  which is subject to market conditions and other factors and
covers the period ending September 30, 2006.  During the first quarter of fiscal
2005, the Company  repurchased  335,036 shares under this program for a total of
$24.9 million and has  approximately  575,000 shares remaining under the program
at March 31, 2005. There were no stock repurchases  during the second quarter of
fiscal 2005.

CRITICAL ACCOUNTING POLICIES
Management has evaluated the accounting  policies used in the preparation of the
Company's financial  statements and related notes and believes those policies to
be reasonable and appropriate.  Certain of these accounting policies require the
application  of  significant  judgment by  management  in selecting  appropriate
assumptions  for  calculating  financial  estimates.   By  their  nature,  these
judgments are subject to an inherent degree of uncertainty.  These judgments are
based on historical experience, trends in the industry,  information provided by
customers and information  available from other outside sources, as appropriate.
The most significant areas involving  management  judgments and estimates may be
found in the Critical Accounting Policies Section of Management's Discussion and
Analysis and in Note 1 to the Consolidated Financial Statements contained in the
Company's  Annual  Report on Form 10-K for the fiscal year ended  September  30,
2004, at Exhibit 13.




OTHER MATTERS

Contingencies

As a normal incident of the businesses in which the Company is engaged,  various
claims, charges and litigation are asserted or commenced against the Company. In
the opinion of  Management,  final  judgments,  if any,  which might be rendered
against the Company in current  litigation are adequately  reserved,  covered by
insurance,  or  would  not  have a  material  adverse  effect  on its  financial
statements.

FORWARD LOOKING STATEMENTS

Statements in this report that are not strictly historical are "forward looking"
statements  within the  meaning of the safe  harbor  provisions  of the  federal
securities  laws.  Forward  looking  statements  include  those  relating to the
estimates  or  projections  made in  connection  with the  Company's  accounting
policies,   annual  effective  tax  rate,  timing  of   Communications   segment
commitments and  expenditures,  continued  growth in the AMR market,  outcome of
current claims and litigation,  future cash flow, and capital  requirements  and
operational needs for the foreseeable future and the amounts, if any, and timing
of foreign earnings repatriated into the U.S. and the additional taxes resulting
from such  repatriation.  Investors are cautioned that such  statements are only
predictions,  and speak only as of the date of this report. The Company's actual
results  in the  future  may  differ  materially  from  those  projected  in the
forward-looking  statements  due to risks and  uncertainties  that  exist in the
Company's  operations and business  environment  including,  but not limited to:
weakening of economic conditions in served markets;  changes in customer demands
or customer insolvencies;  competition; intellectual property rights; successful
execution of the planned sale of the Company's  Puerto Rico  facility;  material
changes  in the costs of  certain  raw  materials  including  steel,  copper and
petroleum based resins;  delivery  delays or defaults by customers;  termination
for convenience of customer  contracts;  timing and magnitude of future contract
awards;  performance  issues with key suppliers,  customers and  subcontractors;
collective  bargaining  and  labor  disputes;  changes  in laws and  regulations
including changes in accounting standards and taxation requirements;  changes in
foreign  or U.S.  business  conditions  affecting  the  distribution  of foreign
earnings; costs relating to environmental matters;  litigation uncertainty;  and
the Company's successful execution of internal operating plans.

ITEM 2.       UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In August 2004, the Company's  Board of Directors  approved the extension of the
previously  authorized  (February 2001) open market repurchase  program of up to
1.1 million shares,  which is subject to market conditions and other factors and
covers the period  ending  September 30, 2006.  There were no stock  repurchases
during the second quarter of fiscal 2005.

ITEM 3.       QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risks relating to the Company's  operations result primarily from changes
in interest rates and changes in foreign currency exchange rates. There has been
no material change to the Company's risks since September 30, 2004. Refer to the
Company's  2004 Annual Report on Form 10-K for further  discussion  about market
risk.

ITEM 4.       CONTROLS AND PROCEDURES

The  Company  carried  out an  evaluation,  under the  supervision  and with the
participation of Management, including the Company's Chief Executive Officer and
Chief Financial Officer, of the effectiveness of the design and operation of the
Company's disclosure controls and procedures as of the end of the period covered
by this  report.  Based upon that  evaluation,  the  Company's  Chief  Executive
Officer and Chief  Financial  Officer  concluded  that the Company's  disclosure
controls and procedures were effective as of that date.  Disclosure controls and
procedures  are  controls  and  procedures  that are  designed  to  ensure  that
information required to be disclosed in Company reports filed or submitted under
the Securities Exchange Act of 1934 (the "Exchange Act") is recorded, processed,
summarized and reported within the time periods  specified in the Securities and
Exchange Commission's rules and forms. There has been no change in the Company's
internal  control over financial  reporting (as defined in Rule 13a-15(f)  under
the Exchange Act) during the period  covered by this report that has  materially
affected,  or is reasonably likely to materially  affect, the Company's internal
control over financial reporting.

          Technologies Inc.;

     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

     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 we 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

               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

               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 and I have disclosed,  based
          on our most recent  evaluation  of  internal  control  over  financial
          reporting,  to the  registrant's  auditors  and the audit and  finance
          committee  of  the   registrant's   board  of  directors  (or  persons
          performing the equivalent functions):

               design or operation of internal control over financial  reporting

               ability  to  record,  process,  summarize  and  report  financial
               information; and

          b.   Any fraud,  whether or not material,  that involves management or

               report;

          3.   Based  on my  knowledge,  the  financial  statements,  and  other
               financial  information included in this quarterly report,  fairly

                    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 report our

                    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 and I have disclosed,  based
          on our most recent  evaluation  of  internal  control  over  financial
