NATIONAL TECHNICAL SYSTEMS, INC. AND SUBSIDIARIES
 Notes to the Unaudited Condensed Consolidated Financial Statements

1.    Basis of Presentation

      In  accordance   with   instructions   to  Form  10-Q,  the   accompanying
      consolidated  financial  statements  and  footnotes of National  Technical
      Systems, Inc. (NTS or the Company) have been condensed and, therefore,  do
      not contain all  disclosures  required by  generally  accepted  accounting
      principles.  These statements  should not be construed as representing pro
      rata  results  of  the  Company's  fiscal  year  and  should  be  read  in
      conjunction  with the financial  statements and notes thereto  included in
      the Company's Form 10-K for the year ended January 31, 2002.

      The  statements  presented  as of and for the three and nine months  ended
      October 31, 2002 and 2001 are  unaudited.  In  Management's  opinion,  all
      adjustments have been made to present fairly the results of such unaudited
      interim periods. All such adjustments are of a normal recurring nature.

      The consolidated  financial statements include the accounts of the Company
      and  its  wholly  owned  and  financially  controlled  subsidiaries.   All
      significant intercompany balances and transactions have been eliminated in
      consolidation.  Certain  prior  year  amounts  have been  reclassified  to
      conform with the current year presentation.

2.    Income Taxes

      Income taxes for the interim  periods are computed using the effective tax
      rates estimated to be applicable for the full fiscal year.

3.    Comprehensive Income

      Accumulated  other   comprehensive   income  on  the  Company's  Condensed
      Consolidated Balance Sheets consists of cumulative equity adjustments from
      foreign  currency  translation.  During the nine and three  months  ending
      October  31,  2002   comprehensive   income  was   $695,000  and  $134,000
      respectively,  which was  equal to net  income  as there  were no  foreign
      currency  translation  adjustments  for such periods.  During the nine and
      three  months  ending  October 31, 2001  comprehensive  income  (loss) was
      $26,000 and ($130,000) respectively. The tax effect related to the foreign

7.    Stock Repurchase

      On February 6, 2001,  the  Company's  Board of  Directors  authorized  the
      repurchase  of  shares  in the  Company's  common  stock  in  open  market
      purchases. During fiscal year 2002, the Company repurchased 88,700 shares.
      The Company's  covenants  with its new banks permit the use in fiscal 2003
      of an additional  maximum  amount equal to 75% of the Company's net profit
      for fiscal year 2002. As of October 31, 2002, the Company had purchased an
      additional 10,700 shares at an average price of $1.73.

8.    Earnings per share

      with Statement of Financial  Accounting  Standards No. 128,  "Earnings Per
      Share"(FAS  128) for all periods  presented.  In accordance  with FAS 128,
      basic  earnings per share have been computed  using the  weighted  average
      number of  shares  of common  stock  outstanding  during  the year.  Basic
      earnings per share excludes any dilutive effects of options,  warrants and
      convertible securities.

9.    Goodwill: Adoption of Statements 141 and 142

      In June 2001, the FASB issued SFAS No. 141,  "Business  Combinations," and
      SFAS No.  142,  "Goodwill  and  Other  Intangible  Assets."  SFAS No.  141
      requires  business  combinations  initiated  after  June  30,  2001  to be
      accounted for using the purchase  method of  accounting,  and broadens the
      criteria for recording  intangible assets apart from goodwill.  Under SFAS
      No. 142,  goodwill and intangible assets that have indefinite useful lives
      will no longer be  amortized  but will be  tested  at least  annually  for
      impairment.  The  goodwill  test for  impairment  consists  of a  two-step
      process that begins with an  estimation of the fair value of the reporting
      unit. The first step of the test is a screen for potential  impairment and
      the second step  measures the amount of  impairment,  if any. SFAS No. 142
      requires an entity to complete the first step of the transitional goodwill
      impairment  test within six months of adopting  the  Statement.  The first
      step of the transitional goodwill impairment test includes a comparison of
      the fair value of each reporting  unit that has  associated  goodwill with
      the carrying value of the reporting unit. The Company adopted SFAS No. 142
      in the first quarter of fiscal 2003. In accordance  with SFAS No. 142, the
      Company  identified two reporting  units,  the  Engineering and Evaluation
      unit and the Technical  Staffing unit, which constitute  components of its
      business that include  goodwill.  The Company  completed the first step of
      the transitional  goodwill  impairment test as of February 1, 2002 and has
      determined that the fair value of each of the reporting units exceeded the
      reporting unit's carrying amount,  and no impairment was indicated.  There
      have been no indications of any impairments through October 31, 2002.

10.   Long-Lived Assets: Adoption of Statement 144

      In  August  2001,  the FASB  issued  SFAS  No.  144,  "Accounting  for the
      Impairment  or Disposal of  Long-Lived  Assets,"  which is  effective  for
      fiscal years  beginning  after December 15, 2001. SFAS 144 supersedes FASB
      Statement  No.  121,   "Accounting  for  the  Impairment  or  Disposal  of
      Long-Lived  Assets and for  Long-Lived  Assets to Be Disposed Of," and the
      accounting and reporting  provisions relating to the disposal of a segment
      of a business of Accounting  Principles  Board Opinion No. 30. The Company
      has adopted SFAS 144  beginning in the first  quarter of fiscal year 2003.
      The  adoption  had no  impact  on  the  Company's  consolidated  financial
      position or results of operations.

11.   On October 14, 2002, XXCAL, Inc., a wholly-owned  subsidiary of Registrant
      ("XXCAL"),  acquired  substantially all of the U.S. assets and business of
      the Information  Technology  Staffing  Division of TRS Staffing  Solutions
      ("TRS"), a New Hampshire corporation and wholly-owned  subsidiary of Fluor
      Corporation for a total purchase price of $1,579,000 consisting of the sum
      of $1,500,000 paid in cash to several  subsidiaries  of Fluor  Corporation
      and $79,000  consisting of transaction  related  costs.  $1,500,000 of the
      initial  purchase  price of $1,579,000  has been allocated to fixed assets
      consisting of furniture and equipment based on an initial  estimate of the
      respective  fair values as of the date of  acquisition  and the  remaining
      balance  of  $79,000  was  allocated  to a covenant  not to  compete.  The
      acquired business has six offices serving  approximately 50 customers with
      more than 330 IT professionals.  The results of operations of the acquired
      business  are  included  in the  accompanying  consolidated  statement  of
      operations from October 14, 2002. By making this acquisition,  the Company
      intends to expand its  presence  and  increase  its  opportunities  in the

Engineering & Evaluation:
- -------------------------
For the nine months ended October 31, 2002,  Engineering and Evaluation revenues
increased  by $523,000 or 1.3% when  compared to the same period in fiscal 2002,
primarily due to an increase in the Company's  traditional  testing business and
revenues  derived from the newly  established  Independent Test Laboratory (ITL)
program,  offset by a  decrease  in  business  in the  technology  sector  which
affected  revenues  in the  computer  testing  and  telecommunications  markets.
Revenues  were also  affected  by the shut down of the Largo,  Florida  facility
during the fourth  quarter of the last  fiscal year and the  negative  effect on
revenues caused by the new highway  adjacent to our Santa Clarita  facility as a
portion of the Company's land was taken by Eminent Domain for the new highway.

Technical Staffing:
- -------------------
For the nine months  ended  October 31,  2002,  revenues in  Technical  Staffing
increased  by  $1,839,000  or 11.7% when  compared  to the same period in fiscal
2002, due to the acquisition of the ongoing information  technology staffing and
engineering  business of TRS Staffing  Solutions  which was effective on October
14, 2002.

Total gross  profit for the nine months  ended  October  31, 2002  increased  by
$469,000 or 3.5% when compared to the same period in fiscal 2002.

Engineering & Evaluation:
- -------------------------
For the nine months ended October 31, 2002,  gross profit for the  Engineering &
Evaluation  Group increased by $845,000 or 8.8% when compared to the same period
in  fiscal  2002,  primarily  as a  result  of the  increase  in  the  Company's
traditional  testing  business and decreased  costs as a result of  streamlining
internal processes.

Technical Staffing:
- -------------------
For the nine months ended October 31, 2002,  gross profit  decreased by $376,000
or (10.3%) in the Technical  Staffing  Group when compared to the same period in
fiscal  2002.  This  decrease  was  primarily  due  to the  competitive  pricing
pressures  in the staffing  industry,  which is forcing the company to lower its
prices in order to retain its  existing  customers  and attract  new  customers.
Additionally,  revenues from the newly  acquired  business  have slightly  lower
gross margin than the existing business.

decrease was offset by additional  expenses related to the acquisition which was
effective on October 14, 2002.

INTEREST EXPENSE

Net interest expense  decreased by $486,000 in the nine months ended October 31,
2002 when  compared  to the same  period  in  fiscal  2002.  This  decrease  was
principally due to lower average debt balances for the nine months ended October
31, 2002 and lower  interest  rate levels when  compared to the same period last
year.


INCOME TAXES

The income tax  provisional  rate of 43.4% for the nine months ended October 31,
2002 reflects a rate in excess of the U.S. federal  statutory rate primarily due
to the  inclusion of state  income  taxes.  This rate is based on the  estimated
provision  accrual for fiscal  year ending  January  31,  2003.  Management  has
determined  that it is more likely than not that the  deferred tax asset will be
realized on the basis of offsetting it against deferred tax  liabilities.  It is
the Company's intention to assess the need for a valuation account by evaluating
the  realizability  of the deferred  tax asset  quarterly  based upon  projected
future taxable income of the Company.

NET INCOME

The increase in net income for the nine months ended October 31, 2002,  compared
to the same period in fiscal 2002, was primarily due to the higher gross profit,
lower selling and administrative expenses and lower interest expense.

BUSINESS ENVIRONMENT

Engineering & Evaluation:
- -------------------------

The Company's basic service is to provide product certification,  product safety
testing and product  evaluation to ensure its clients' products meet established
specifications or standards.  In recent years,  domestic and worldwide political
and economic  developments have  significantly  affected the markets for defense
and advanced technology  systems.  Homeland security and defeating terrorism are
among the  Department  of  Defense's  main  initiatives.  Budget  increases  are
projected for operational readiness spending as well as research and development
spending.


                                       15


The   Company   has   realized   a   significant   increase   in  sales  at  its
military/aerospace  facilities  since the  September 11, 2001  catastrophe.  The
Company's Santa Clarita facility, its largest military/aerospace  facility, has,
however,   experienced  a  decline  in  sales  during  this  period,   following
construction  of a public  highway  immediately  adjacent  to the Santa  Clarita
facility.   The  highway,  which  overlooks  the  Santa  Clarita  facility,  has
heightened the concerns of customers who require  testing of sensitive  programs
and has caused certain  customers to stop using the facility for those programs.
A portion of the  highway was built on real  property  taken from the Company by
eminent  domain.  NTS  is  seeking,  through  the  legal  process,   appropriate
compensation   for  the  taking  of  the  Company's   property.   If  sufficient
compensation is awarded,  NTS will utilize same to implement mitigating measures
which NTS hopes will enable the Company to continue  operations at this facility
using most of its capabilities.  In an effort to maintain the economic viability
of the  facility,  several new  capabilities  have been added which include fuel
cell testing,  upgraded acoustical testing,  clean environment satellite testing
and installation of a high-pressure air system.

Growth  for the  balance  of the year  will be  dependent  on  overall  economic
conditions  and the  increases  in  research  and  development  spending  in the
aerospace, defense and telecommunication industries.

Technical Staffing:
- -------------------

The Company provides a variety of staffing and workforce management services and
solutions,  including  contract,  contract-to-hire  and  full time placements to
meet its  clients'  needs.  One of the  strategies  for  growth is to extend the
offering of the Company's  services to its Engineering & Evaluation  clients and
provide   technical   and   engineering   personnel  as  a  complete   suite  of
certification,  registration and test services.  The goal is to offer a complete
solution  to  the  clients'  product   development  needs,  which  will  include
consultants and technical experts provided by the staffing segment.

Notwithstanding  the foregoing,  and because of factors  affecting the Company's
operating results,  past financial  performance should not be considered to be a
reliable indicator of future performance.

LIQUIDITY AND CAPITAL RESOURCES

For the nine  months  ended  October  31,  2002,  cash  provided  by  operations
decreased by $3,075,000  when  compared to the same period in fiscal 2002.  This
decrease  was  primarily  due  to  an  increase  in  accounts   receivables  and
inventories, and a decrease in deferred income, partially offset by increases in
net income and decreases in accrued expenses.

Net cash used in investing activities in the nine-month period ended October 31,
2002  increased by  $1,211,000  when compared to the same period in fiscal 2002,
primarily due to cash paid for an acquisition,  partially  offset by the sale of
property, during the nine-month period ended October 31, 2002.

In the  nine-month  period ended  October 31,  2002,  net cash used by financing
activities decreased by $2,213,000 over the same period in fiscal 2002. Net cash
used by financing  activities  consisted of the repayment of lines of credit and
short term and long term debt of  $3,280,000  and  repurchase of common stock of
$19,000,  partially  offset by  proceeds  from lines of credit and term loans of
$2,729,000.

The Company had a credit  agreement with United  California Bank (formerly Sanwa
Bank  California),  as agent,  and Mellon Bank, which included (1) a $10,000,000
revolving line of credit at an interest rate equal to the agent bank's reference
rate  expiring  November 1, 2002 and (2) a  $6,500,000  term loan at an interest
rate of 8.31%  expiring in January 2003. In September  2001,  the line of Credit
was reduced to  $9,700,000.  On November  21,  2001,  the Company  replaced  the
outstanding  debt to United  California  Bank and Mellon Bank with a $16,000,000
reducing  revolving line of credit with Comerica Bank California and First Bank,
expiring  on August 1, 2004.  On November  25,  2002,  the  Company  amended the
revolving line of credit with Comerica Bank California and First Bank increasing
it to $20,000,000.  Comerica Bank California,  as the agent Bank, is sharing 60%
of the line with First Bank, as the participant  Bank,  sharing 40% of the line.
The revolving line of credit will be reduced by $1,750,000 on August 1, 2003 and
each year thereafter. If during any fiscal year, the Company's net income equals
or exceeds $2,000,000, there will be no required reduction in the revolving line
of credit.  The interest rate is at the agent bank's prime rate,  with an option
for the Company to convert to loans at the Libor rate plus 250 basis  points for
30, 60, 90, 180 or 365 days,  with minimum  advances of $1,000,000.  The Company
paid a 0.5%  commitment fee of the total line amount and is paying an additional
0.25% of the commitment  amount  annually and a 0.25% fee for any unused line of
credit.  The outstanding  balance on the revolving line of credit at October 31,
2002 was $12,702,000. This balance is reflected in the accompanying consolidated
balance  sheets as long-term.  This  agreement is subject to certain  covenants,
which  require  the  maintenance  of certain  working  capital,  debt-to-equity,
earnings-to-expense  and cash flow  ratios.  The Company was in full  compliance
with all of the covenants with its banks as of October 31, 2002.

The Company has  additional  equipment  line of credit  agreements  (at interest
rates of 6.02 % to 10.25%) to finance  various test  equipment  with terms of 60
months for each equipment schedule.  The outstanding balance at October 31, 2002
was $2,887,000.

At October 31, 2002, the balance of other notes payable  collateralized  by land
and building was $3,444,000, and the balance of unsecured notes was $517,000.

2.      Based on my knowledge, this quarterly report does not contain any untrue
        statement of a material fact or omit to state a material fact  necessary
        to make the statements made, in light of the  circumstances  under which
        such  statements  were made, not  misleading  with respect to the period
        covered by this quarterly report;

3.      Based on my knowledge,  the financial  statements,  and other  financial
        information  included in this  quarterly  report,  fairly present in all
        material  respects the financial  condition,  results of operations  and
        cash flows of the  registrant  as of, and for, the periods  presented in
        this quarterly report;

4.      The  registrant's  other  certifying  officers and I are responsible for
        establishing  and  maintaining  disclosure  controls and  procedures (as
        defined in Exchange Act Rules 13a-14 and 15d-14) for the  registrant and
        we have:

        a)    designed such  disclosure  controls and  procedures 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;

              effectiveness  of the disclosure  controls and procedures based on
              our evaluation as of the Evaluation Date;

5.      The registrant's other certifying  officers and I have disclosed,  based
        on our most recent  evaluation,  to the  registrant's  auditors  and the
        audit  committee  of   registrant's   board  of  directors  (or  persons
        performing the equivalent function):

        a)    all  significant  deficiencies  in  the  design  or  operation  of
              internal  controls which could adversely  affect the  registrant's
              ability to record,  process,  summarize and report  financial data
              and have  identified  for the  registrant's  auditors any material
              weaknesses in internal controls; and

        b)    any fraud,  whether or not material,  that involves  management or
              other  employees who have a significant  role in the  registrant's
              internal  controls;  and

6.      The registrant's other certifying  officers and I have indicated in this
        quarterly  report  whether  or not there  were  significant  changes  in
        internal  controls or in other factors that could  significantly  affect

        including any corrective actions with regard to significant deficiencies
        and material weaknesses.

multiplied by (ii) one quarter of one percent (0.25%); provided, however, if the
Revolving Loans Maturity Date shall occur within 12 months of November 30 of the
current year,  then Borrowers shall pay a Facility Fee in an amount equal to the
result of (i) the Total  Credit as in effect on November 30 of the current  year
multiplied by (ii) one quarter of one percent  (0.25%)  multiplied by the result
of (x) the number of months  (or  fractions  thereof)  from  November  30 of the
current year through and including the Revolving  Loans Maturity Date divided by
(y) 12. The Facility Fee shall be fully earned and non-refundable,  and shall be
due and payable on November 30 of each year."


                                       21




      Amendments to Section  7.15(c).  Section  7.15(c) is hereby amended in its

the  Agreement is hereby  amended in its entirety and replaced with the Schedule
1.1C attached hereto and incorporated hereby.

      Conditions  Precedent to Effectiveness of Amendment.  The effectiveness of
this  Amendment is subject to and  contingent  upon the  fulfillment of each and
every one of the following conditions:

            Agent shall have  received,  for the pro rata account of Lenders,  a
line increase fee equal to $13,750,

            Agent  shall  have  received  this   Amendment,   duly  executed  by
Borrowers, Lenders and Agent;

            No Event of Default,  Unmatured Event of Default or Material Adverse
Effect shall have occurred; and

            All of the  representations  and warranties set forth herein, in the
Loan Documents and in the Agreement shall be true,  complete and accurate in all
respects as of the date hereof (except for  representations and warranties which
are expressly stated to be true and correct as of the Closing Date).

      Representations  and  Warranties.  In order to induce Agent and Lenders to
enter into this Amendment, each Borrower hereby represents and warrants to Agent
and Lenders that:

            No Event of Default or Unmatured Event of Default is continuing;

            All of the representations and warranties set forth in the Agreement
and the Loan Documents are true,  complete and accurate in all respects  (except
for  representations  and warranties  which are expressly  stated to be true and
correct as of the Closing Date); and

            This  Amendment  has been duly  executed and delivered by Borrowers,
and after giving effect to this Amendment,  the Agreement and the Loan Documents
continue to constitute the legal,  valid and binding  agreements and obligations
of  Borrowers,   enforceable   in  accordance   with  their  terms,   except  as
enforceability  may be limited by bankruptcy,  insolvency,  and similar laws and
equitable principles affecting the enforcement of creditors' rights generally.

      Counterparts;  Telefacsimile Execution.  This Amendment may be executed in
any number of counterparts  and by different  parties on separate  counterparts,
each of which,  when executed and delivered,  shall be deemed to be an original,
and all of which,  when taken  together,  shall  constitute but one and the same
Amendment.   Delivery  of  an  executed   counterpart   of  this   Amendment  by
telefacsimile  shall be equally as effective as delivery of a manually  executed
counterpart of this Amendment.  Any party delivering an executed  counterpart of
this  Amendment  by  telefacsimile   also  shall  deliver  a  manually  executed
counterpart  of this  Amendment  but the failure to deliver a manually  executed
counterpart shall not affect the validity, enforceability, and binding effect of
this Amendment.

      Integration.  The Agreement as amended by this Amendment  constitutes  the
entire  agreement and  understanding  between the parties hereto with respect to
the  subject  matter  hereof  and  thereof,  and  supersedes  any and all  prior
agreements and understandings,  oral or written,  relating to the subject matter
hereof and thereof.

      Reaffirmation  of the  Agreement.  The Agreement as amended hereby and the
other Loan Documents remain in full force and effect.
