                     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,  2005.  During 2005,  the Company had a 2-for-1  stock split
     which  was  effected  as a 100  percent  stock  dividend  and  was  paid on
     September 23, 2005. The prior years common stock and per share amounts have
     been adjusted to reflect the stock split.

     The results  for the three month  period  ended  December  31, 2005 are not
     necessarily indicative of the results for the entire 2006 fiscal year.



2.   EARNINGS PER SHARE (EPS)

     Basic EPS is calculated  using the weighted average number of common shares

3.   SHARE-BASED COMPENSATION

     Prior to October 1, 2005, the Company  accounted for its stock option plans
     using the intrinsic  value method of accounting  provided under APB Opinion
     No. 25,  "Accounting  for Stock Issued to Employees,"  (APB 25) and related
     interpretations,  as permitted by FASB Statement No. 123,  "Accounting  for
     Stock-Based  Compensation,"  (SFAS 123) under which no compensation expense
     was   recognized  for  stock  option   grants.   Accordingly,   share-based
     compensation  for stock  options was included as a pro forma  disclosure in
     the financial  statement footnotes and continues to be provided for periods
     prior to fiscal 2006.

     Effective  October 1, 2005, the Company adopted the fair value  recognition
     provisions of FASB  Statement  No. 123 (R),  "Share-Based  Payment,"  (SFAS
     123(R))  using  the  modified-prospective  transition  method.  Under  this
     transition  method,  compensation  cost  recognized in the first quarter of
     fiscal 2006 includes:

     a)   compensation  cost  for  all  share-based   payments  granted  through
          September  30, 2005,  for which the requisite  service  period had not
          been completed as of September 30, 2005,  based on the grant date fair
          value  estimated in  accordance  with the original  provisions of SFAS
          123, and

     b)   compensation cost for all share-based  payments granted  subsequent to
          September  30, 2005,  based on the grant date fair value  estimated in
          accordance  with the  provisions  of SFAS  123(R).  Results  for prior
          periods have not been restated.

     As a result of  adopting  SFAS  123(R) on October 1,  2005,  the  Company's
     earnings  before  income taxes and net earnings for the first quarter ended
     December  31,  2005 are $0.5  million  lower  than if it had  continued  to
     account for  share-based  compensation  under APB 25. Diluted  earnings per
     share for the first  quarter  of fiscal  2006  would have been $0.10 if the
     company had not adopted SFAS 123(R),  compared to reported diluted earnings
     per share of $0.08.

     The Company provides  compensation  benefits to certain key employees under
     several  share-based  plans  providing for employee  stock  options  and/or
     performance-accelerated  restricted  shares  (restricted  shares),  and  to
     non-employee directors under a non-employee directors compensation plan.

     Stock Option Plans

     The Company has various stock option plans that permit the Company to grant
     key  Management  employees (1) options to purchase  shares of the Company's
     common  stock or (2) stock  appreciation  rights with respect to all or any
     part of the  number of  shares  covered  by the  options.  All  outstanding
     options  were  granted at prices  equal to fair market value at the date of
     grant.  The options  granted  prior to  September  30, 2003 have a ten-year
     contractual life from date of issuance, expiring in various periods through
     2013.  Beginning  in fiscal  2004,  the  options  granted  have a five-year
     contractual life from date of issuance.  No stock appreciation  rights have
     been awarded to date.  The  Company's  stock  option  awards are subject to
     graded vesting over a three year service period. Beginning with fiscal 2006
     awards, the Company recognizes  compensation cost on a straight-line  basis
     over the requisite  service  period for the entire  award.  Prior to fiscal
     2006,  the Company  calculated  the pro forma  compensation  cost using the
     graded vesting method (FIN 28 approach).

     The fair value of each option  award is  estimated  as of the date of grant
     using  a  Black-Scholes   option  pricing  model.   The  weighted   average
     assumptions for the periods indicated are noted below.  Expected volatility
     is based on  historical  volatility  of ESCO's  stock  calculated  over the
     expected term of the option. The expected term was calculated in accordance
     with Staff  Accounting  Bulletin  No. 107 using the  simplified  method for
     "plain-vanilla"  options.  The risk-free  rate for the expected term of the
     option is based on the U.S.  Treasury  yield curve in effect at the date of
     grant.

     The fair value of each option grant is estimated on the date of grant using
     the Black-Scholes  option-pricing model with the following weighted-average
     assumptions  used for grants in the three month period  ended  December 31,
     2005 and 2004, respectively: expected dividend yield of 0% in both periods;
     expected volatility of 28.6% and 28.3%; risk-free interest rate of 4.5% and
     3.6%;  and expected term of 3.5 years and 4.2 years.  Pre-tax  compensation
     expense  related to the stock option  awards was $0.5 million for the first
     quarter of fiscal 2006.

     The following  summary presents  information  regarding  outstanding  stock
     options as of December 31, 2005 and changes  during the first  quarter then
     ended with regard to options under the option plans:

     The  weighted-average  grant-date  fair value of options granted during the
     first quarter ended December 31, 2005 was $11.74.

     During fiscal 2004, the Board of Directors  authorized and the shareholders
     approved, the 2004 Incentive Compensation Plan, which states, in part, that
     on  February  5,  2004,  there  shall  be added  to the  authorized  shares
     allocated   2,000,000  shares  for  the  grant  of  stock  options,   stock
     appreciation  rights,  performance-accelerated  restricted  stock, or other
     full value  awards.  Of these,  shares up to 600,000  may be  utilized  for
     performance-accelerated restricted stock or other full value awards.

     Restricted Share Awards

     At December 31, 2005, the maximum number of restricted shares available for
     issue  under  the 2004  Incentive  Compensation  Plan  and the  2001  Stock
     Incentive Plan was 600,000 and 361,162 shares,  respectively.  These shares
     vest over five years with  accelerated  vesting over three years if certain
     performance  targets are achieved.  In these cases,  if it is probable that
     the performance condition will be met, the Company recognizes  compensation
     cost  on  a  straight-line  basis  over  the  shorter  performance  period;
     otherwise,  it will  recognize  compensation  cost over the longer  service
     period.  Compensation  cost for all outstanding  restricted share awards is
     being recognized over the shorter  performance period as it is probable the
     performance  condition will be met. The restricted  share award grants were
     valued  at the  stock  price on the  date of  grant.  Compensation  expense
     related to the restricted share awards was $0.6 million for the three-month
     periods ended December 31, 2005 and 2004, respectively.

9.   RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     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. At December  31, 2005,  the range of  reasonably  possible  amounts of
     unremitted  earnings that are being  considered for repatriation is between
     zero and $39.5 million, which would require the Company to pay income taxes
     in the  range  of  zero  to  $3.1  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.  References to the first  quarters of 2006
     and 2005  represent the fiscal  quarters  ended December 31, 2005 and 2004,
     respectively.

     NET SALES

     Net sales decreased $13.8 million, or 13.2%, to $90.6 million for the first
     quarter  of 2006  from  $104.4  million  for the  first  quarter  of  2005,
     primarily due to a decrease in sales in the Communications segment of $14.4
     million. Unfavorable foreign currency values resulted in approximately $1.0
     million of the sales decrease realized in the 2006 first quarter.

     -Filtration/Fluid Flow

     Net sales  decreased $2.5 million,  or 5.7%, to $41.5 million for the first
     quarter of 2006 from $44.0 million for the first quarter of 2005. The sales
     decrease  during the fiscal  quarter ended December 31, 2005 as compared to
     the prior year quarter is mainly due to the following: lower defense spares
     and T-700  shipments  at VACCO of $2.5  million;  a net sales  decrease  at
     Filtertek of $0.5 million  driven by lower  automotive  shipments and lower
     volumes  in  France;   partially  offset  by  higher  commercial  aerospace
     shipments at PTI of $0.5 million.

     -Communications

     Net sales decreased $14.4 million, or 43.0%, to $19.1 million for the first
     quarter of 2006 from $33.5 million for the first quarter of 2005. The sales
     decrease in the first  quarter of 2006 as compared to the prior year period
     was due to $11.0  million  of lower  shipments  of DCSI's  automatic  meter
     reading  (AMR)  products and $4.6  million of lower  shipments of Comtrak's
     SecurVision  video security  products.  The Nexus acquisition  contributed
     $1.2 million in sales in the first quarter of fiscal 2006 which represented
     one month of sales.

     The  decrease in sales of AMR  products  for the three month  period  ended
     December  31,  2005 as  compared  to the prior year  quarter was due to the
     following items: $9.9 million of lower AMR product sales to the COOP market
     due to the  weakness  in orders  entered  during the latter  half of fiscal
     2005;  $2.2  million of lower sales to legacy  customers  such as Wisconsin
     Public Service (WPS),  Bangor Hydro,  Puerto Rico Power Authority  (PREPA),
     and  PPL  Electric  Utilities   Corporation  (PPL).  These  decreases  were
     partially  offset by sales to TXU Electric  Delivery  Company (TXU) of $1.5
     million  in the first  quarter of 2006.  During the first  quarter of 2006,
     DCSI's  sales to COOP and public  power  (Municipal)  customers  were $11.5
     million compared to $21.4 million in the first quarter of 2005.

     Sales of  SecurVision  products  were $2.5 million for the first quarter of
     2006 as compared  to $7.1  million  for the prior year first  quarter.  The
     decrease in sales was due to an acceleration of shipments in the prior year
     quarter  to  catch  up  on  backlog   resulting   from   certain   software
     modifications.

     -Test

     For the  first  quarter  of 2006,  net  sales of $30.0  million  were  $3.2
     million,  or 11.9% higher than the $26.8  million of net sales  recorded in
     the first quarter of 2005. The sales increase as compared to the prior year
     quarter was mainly due to the  following:  a $4.8  million  increase in net
     sales from the Company's U.S.  operations driven by additional test chamber
     installations  and  higher  component  sales;  partially  offset  by a $1.5
     million decrease in net sales from the Company's European operations due to
     the prior year completion of several large test chamber projects.



     ORDERS AND BACKLOG

     Backlog  was $268.7  million at  December  31,  2005  compared  with $233.1
     million at September  30, 2005.  The Company  received new orders  totaling
     $126.1 million in the first quarter of 2006  (including $2.0 million of new
     orders and $9.0  million of acquired  backlog  from  Nexus).  New orders of
     $41.1  million were received in the first quarter of fiscal 2006 related to
     Filtration/Fluid  Flow products,  $59.2 million  related to  Communications
     products and $25.8 million related to Test products.

     Within the  Communications  segment,  DCSI  received  $45.6  million of new
     orders for its AMR products in the first quarter of 2006,  which included a
     $9.4 million  follow-on order from TXU for a 100,000 endpoint  expansion of
     the existing program.

     In addition,  in November 2005,  DCSI signed an agreement with PG&E with an
     anticipated  contract  value of  approximately  $300 million  covering five
     million  endpoints  over a five year  deployment  period  beginning in late
     fiscal 2006. The Company received a $0.4 million order from PG&E under this
     agreement during the first quarter of 2006. See "Recent Development."


     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 29.3% and 34.4% in the first
     quarters of fiscal 2006 and 2005,  respectively.  The decrease in the gross
     profit  margin in the first  quarter of 2006 as  compared to the prior year
     quarter is mainly  due to the lower  sales  volumes  in the  Communications
     segment and $1.0 million of pre-tax  charges at DCSI  consisting  of a $0.4
     million   write-off  of  assets   related  to  a   terminated   subcontract
     manufacturer  and $0.6  million of warranty  costs  related to a commercial
     transponder. In addition, VACCO's and Filtertek's gross profit margins were
     negatively  impacted by lower defense spares  shipments and the softness in
     the automotive market, respectively.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling,  general and administrative  (SG&A) expenses for the first quarter
     of fiscal 2006 were $23.6 million (26.1% of net sales), compared with $19.8
     million  (19.0% of net sales) for the prior year  quarter.  The increase in
     SG&A  spending  in the first  quarter of 2006 as compared to the prior year
     quarter  is  primarily  due  to  the  following   items:   an  increase  of
     approximately $1.0 million  associated with engineering,  marketing and new
     product development within the Communications segment; $0.7 million of SG&A
     expenses  related to the Nexus  acquisition;  and $0.5  million  related to
     stock option expense.

     OTHER  (INCOME)  EXPENSES,  NET

     Other (income) expenses,  net, were $(0.1) million for the first quarter of
     2006  compared  to $(0.5)  million  for the prior year  quarter.  Principal
     components of other (income)  expenses,  net, for the first quarter of 2006
     included $(0.6) million of royalty income; partially offset by $0.3 million
     of  amortization  expense  of  identifiable  intangible  assets  (primarily
     patents,  licenses and  software);  and a $0.2 million  write off of assets
     related to a terminated subcontract  manufacturer.  Principal components of
     other (income) expenses, net, for the first quarter of 2005 included $(0.6)
     million of  royalty  income and $0.2  million  of  amortization  expense 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 $3.0  million  (3.3% of net sales) for the
     first quarter of 2006 and $16.5 million  (15.8% of net sales) for the first
     quarter  of 2005.  The  decrease  in EBIT for the first  quarter of 2006 as
     compared to the prior year quarter is primarily  due to the sales  decrease
     in the Communications 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 $4.1 million  (9.9% of net sales) and $7.1  million  (16.0% of net
     sales) in the first quarters of 2006 and 2005, respectively.  For the first
     quarter of 2006 as compared to the prior year quarter,  EBIT decreased $3.0
     million due to the following: a $1.7 million decrease at VACCO due to lower
     defense  spares  shipments;  a  $1.4  million  net  decrease  at  Filtertek
     primarily  due to softness  in the  automotive  market and  increase in raw
     material costs (e.g.  petroleum  based resins).  Additionally,  Filtertek's
     prior year  first  quarter  included  $0.6  million  of cost  reimbursement
     related to a supply  agreement  with a medical  device  customer  which was
     terminated in fiscal 2005.

     -Communications

     EBIT in the first  quarter of 2006 was a loss of $1.0  million  compared to
     EBIT of $9.6  million  (28.7% of net sales) in the prior year  period.  The
     decrease  in EBIT in the  first  quarter  of 2006 was due to the  following
     items:  a $6.9  million  decrease  at DCSI  due to lower  shipments  of AMR
     products;  a $1.0  million  increase  in DCSI's  SG&A  expenses  related to
     additional engineering, marketing and new product development; $1.0 million
     in charges at DCSI related to the  subcontractor  and warranty issues noted
     above;  a $1.8  million  decrease at Comtrak due to lower  shipments of its
     video security  products;  partially offset by a $0.2 million  contribution
     from the Nexus acquisition for its one month of operations.

     -Test

     EBIT in the first  quarter of 2006 was $2.9 million  (9.7% of net sales) as
     compared to $2.1 million  (7.8% of net sales) in the prior year period.  In
     the first quarter of 2006, EBIT increased $0.8 million due to the favorable
     changes in sales mix resulting from additional test chamber  installations,
     and sales of antennas and other components.  EBIT in the prior year quarter
     was  adversely  affected  by $0.3  million of  installation  cost  overruns
     incurred on certain government shielding projects in foreign locations,  as
     well as increased material costs (steel and copper).

     -Corporate

     Corporate costs included in EBIT were $3.1 million for the first quarter of
     fiscal  2006  compared  to $2.3  million  for the prior year  quarter.  The
     increase in Corporate costs in the first quarter of fiscal 2006 as compared
     to the prior year quarter is primarily  due to the  implementation  of SFAS
     123(R) which  resulted in $0.5 million of  incremental  expense  related to
     stock options.

     INTEREST INCOME, NET

     Interest income, net, was $0.7 million and $0.5 million for the three month
     periods  ended  December 31, 2005 and 2004,  respectively.  The increase in
     interest  income in the first quarter of 2006 as compared to the prior year
     quarter is due to favorable interest rates in fiscal 2006.

     INCOME TAX EXPENSE

     The first  quarter  2006  effective  income tax rate was 40.4%  compared to
     38.1% in the first quarter of 2005.  The increase in the  effective  income
     tax rate in the first  quarter of fiscal 2006 as compared to the prior year
     period is primarily due to the timing and volume of profit contributions of
     the Company's  foreign  operations  (primarily  Puerto  Rico).  The Company
     estimates the annual effective tax rate for fiscal 2006 to be approximately
     39%.

     CAPITAL RESOURCES AND LIQUIDITY

     Working  capital  (current  assets less current  liabilities)  decreased to
     $166.1  million at December 31, 2005 from $202.2  million at September  30,
     2005. During the first quarter of 2006, cash decreased $34.1 million, which
     included  $28.8  million  paid  for  the  Nexus  acquisition.   Inventories
     increased  by $4.1  million  in the first  quarter  of 2006,  of which $2.7
     million  related to the  Filtration  segment  due to the timing of expected
     sales and $0.9 million related to the  Communications  segment (new product
     offerings and safety stock to satisfy customer requirements).

     Net cash  provided  by  operating  activities  was $1.9  million  and $15.5
     million  for the  three-month  periods  ended  December  31, 2005 and 2004,
     respectively.  The decrease in the first quarter of 2006 as compared to the
     prior year quarter was a result of the lower  earnings and working  capital
     requirements.

     Capital  expenditures  were  $2.3  million  and $2.0  million  in the first
     quarter of 2006 and 2005,  respectively.  Major expenditures in the current
     period included  manufacturing  equipment used in the Filtration/Fluid Flow
     businesses.

     At December 31, 2005, other assets  (non-current) of $40.1 million included
     $26.0 million of capitalized  software.  Approximately $22.9 million of the
     capitalized  software balance represents external  development costs on new
     software  development  called  "TNG" within the  Communications  segment to
     further penetrate the investor owned utility market. TNG is being developed
     in  conjunction  with a  third  party  software  contractor.  TNG is  being
     deployed to  efficiently  handle the  additional  levels of  communications
     dictated by the size of the service  territories and the frequency of reads
     that are required  under  time-of-use  or critical  peak pricing  scenarios
     needed to meet the  requirements  of large IOUs. At December 31, 2005,  the
     Company  had  approximately  $11  million  of  commitments  related  to TNG
     versions  1.5 and 1.6  which is  expected  to be spent  over the next  nine
     months.  The  Company  expects to spend up to $5  million  in fiscal  2007.
     Amortization of TNG will be on a  straight-line  basis over seven years and
     will begin in February 2006.

     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 December 31, 2005.
     The facility is being marketed for sale.

     In  October  2004,  the  Company  entered  into  a $100  million  five-year
     revolving bank credit facility with a $50 million  increase option that has
     a final  maturity and  expiration  date of October 6, 2009. At December 31,
     2005, the Company had approximately $98.6 million available to borrow under
     the credit  facility in addition to $70.4 million cash on hand. At December
     31, 2005, the Company had no borrowings,  and outstanding letters of credit
     of $2.5  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.

     Acquisition

     Effective  November 29, 2005, the Company  acquired Nexus Energy  Software,
     Inc.  (Nexus)  through  an all  cash  for  shares  merger  transaction  for
     approximately $29 million in cash plus contingent cash  consideration  over
     the four year period  following the merger if Nexus  exceeds  certain sales
     targets.   Nexus  is  a  software   company   headquartered  in  Wellesley,
     Massachusetts with annual revenues in excess of $10 million.  The operating
     results for Nexus,  since the date of acquisition,  are included within the
     Communications  segment. The Company recorded  approximately $24 million of
     goodwill  as  a  result  of  the   transaction,   subject  to  post-closing
     adjustments including finalization of purchase accounting. The Company also
     recorded  $2.7 million of  identifiable  intangible  assets  consisting  of
     customer  contracts  and  backlog  value  which  will  be  amortized  on  a
     straight-line   basis  over  a  period  not  to  exceed  three  years.  The
     post-closing  purchase  accounting items are expected to be completed prior
     to September 30, 2006.

     Recent Development

     On November 7, 2005,  the Company  announced  that DCSI had entered  into a
     contract  to provide  equipment,  software  and  services  to Pacific Gas &
     Electric  (PG&E) in support  of the  electric  portion  of PG&E's  Advanced
     Metering  Infrastructure  (AMI)  project.  PG&E's  current AMI project plan
     calls for the purchase of TWACS communication  equipment for approximately
     five  million  electric   customers  over  a  five-year  period  after  the
     commencement of full deployment.  The total anticipated contract value from
     commencement through the five-year full deployment period is expected to be
     approximately  $300  million.  PG&E has the  right to  purchase  additional
     equipment and services to support  existing and new  customers  through the
     twenty  to  twenty-five  year  term  of the  contract.  Equipment  will  be
     purchased  by PG&E  only upon  issuance  of  purchase  orders  and  release
     authorizations.  PG&E will continue to have the right to purchase  products
     or  services  from  other  suppliers  for the  electric  portion of the AMI
     project.  Full deployment is contingent upon  satisfactory  system testing,
     regulatory  approval  and final PG&E  management  approval all of which are
     currently  scheduled to be concluded during fiscal 2006. DCSI has agreed to
     deliver to PG&E versions of its newly developed TNG software as they become
     available  and are tested.  Acceptance  of the final version for which DCSI
     has  committed is  currently  anticipated  in the latter  portion of fiscal
     2007. Until such acceptance is obtained, the Company will be required under
     U.S.  financial  accounting  standards to defer  revenue  recognition.  The
     contract  provides  for  liquidated  damages  in the event of  DCSI's  late
     development   or  delivery  of  hardware   and   software,   and   includes
     indemnification  and  other  customary  provisions.  The  contract  may  be
     terminated by PG&E for default,  for its  convenience and in the event of a
     force majeure lasting beyond certain  prescribed  periods.  The Company has
     guaranteed the  obligations of DCSI under the contract.  If PG&E terminates
     the contract for its convenience,  DCSI will be entitled to recover certain
     costs.



     Subsequent Event

     On February 2, 2006, the Company  announced the  acquisition of the capital
     stock of Hexagram,  Inc. (Hexagram) for cash consideration of $67.5 million
     and a potential working capital adjustment.  The acquisition agreement also
     provides for contingent  consideration of up to $6.25 million over the five
     year period  following the  acquisition if Hexagram  exceeds  certain sales
     targets.  Hexagram  is a well  established  RF fixed  network  AMR  company
     headquartered  in Cleveland,  Ohio.  The Company's  annual revenue over the
     past three years has been in the range of $20 million to $35 million.

     On November 3, 2005, Hexagram entered into a contract to provide equipment,
     software  and  services  to PG&E in support of the gas  utility  portion of
     PG&E's  AMI  project.   The  total   anticipated   contract   revenue  from
     commencement  through  the  five-year  full  deployment  is  expected to be
     approximately  $225 million.  As with DCSI's contract with PG&E,  discussed
     above,  equipment will be purchased  only upon issuance of purchase  orders
     and  release  authorizations,  and PG&E will  continue to have the right to
     purchase  from  other  suppliers  for the gas  utility  portion  of the AMI
     project.  Full deployment is contingent upon  satisfactory  system testing,
     regulatory approval and final PG&E management approval,  which are expected
     to be concluded  during fiscal 2006.  The contract  provides for liquidated
     damages in the event of late deliveries, includes indemnification and other
     customary  provisions,  and may be terminated by PG&E for default,  for its
     convenience  and in the event of a force  majeure  lasting  beyond  certain
     prescribed  periods.  The Company has  guaranteed  the  performance  of the
     contract by Hexagram.

     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, 2005 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.


     RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     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. At December  31, 2005,  the range of  reasonably  possible  amounts of
     unremitted  earnings that are being  considered for repatriation is between
     zero and $39.5 million, which would require the Company to pay income taxes
     in the  range  of  zero  to  $3.1  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.


     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,   costs  related  to  share-based
     compensation,  outcome of current claims and litigation,  future cash flow,
     and capital  requirements and operational needs for the foreseeable  future
     and the ultimate  value of the DCSI / PG&E contract and the Hexagram / PG&E
     contract,  the future  delivery and acceptance of the TNG software by PG&E,
     completion of Nexus post-closing purchase accounting items, 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: actions by the California Public
     Utility  Commission,  PG&E's  Board  of  Directors  and  PG&E's  management
     impacting  PG&E's AMI projects;  the timing and success of DCSI's  software
     development  efforts;  the timing and  content of purchase  order  releases
     under PG&E's contracts; the Company's successful performance under the PG&E
     contracts;  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

     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 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, 2005.  Refer to the Company's Annual Report on Form 10-K for the fiscal
     year ended September 30, 2005 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.

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

     the  previously   authorized  (February  2001)  open  market  common  stock
     repurchase program originally  authorizing up to 2.6 million shares,  which
     is subject to market  conditions  and other  factors  and covers the period

               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;

          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  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
                    conclusions   about  the  effectiveness  of  the  disclosure
                    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 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):

               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.
