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 Registrant's Form
      10-K for the year ended January 31, 1998 and the financial statements and
      footnotes included in NTS's Form 8-K filed with the Securities and
      Exchange Commission on November 3, 1998 and the Registration Statement on
      Form S-3 (File No. 333-66795) filed with the Securities and Exchange
      Commission on November 4,1998.

      On October 30, 1998, NTS completed its merger with XXCAL, Inc. and
      acquisition of XXCAL Limited (together, "XXCAL"). The merger was treated
      as a pooling of interests whereby NTS issued to the shareholders of XXCAL
      1,297,878 shares of NTS common stock constituting 15.6% of the outstanding
      common stock of NTS after giving effect to the merger. NTS has also
      reserved an additional 214,622 shares of its common stock for issuance
      upon exercise of outstanding XXCAL stock options that were assumed by the
      Company.

      The statements presented as of and for the nine-month and three-month
      periods ended October 31, 1998 and 1997 are unaudited and are presented
      based on the "pooling of interests" method of accounting pursuant to
      Opinion No. 16 of the Accounting Principles Board (APB 16). They include
      the combined financial statements of NTS and XXCAL from the beginning of
      the fiscal year. All prior year financial statements have also been
      restated to reflect the pooling of interests method of accounting. In
      management's opinion, all adjustments have been made to present fairly the
      results of such unaudited interim periods.

      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.

2     Merger Costs

      For the nine months ended October 31, 1998, the Company incurred $906,000
      in one-time merger costs related to outside consulting, accounting, legal
      fees and other fees and expenses specifically associated with the merger
      between NTS and XXCAL and in accordance with APB 16 these costs were
      expensed as incurred. The majority of these merger costs are
      non-deductible for tax purposes.

3.    Start-Up Expenses

      In April 1998, the American Institute of Certified Public Accountants
      issued Statement of Position 98-5, "Reporting the Costs of Start-Up
      Activities", which requires that costs related to start-up activities be
      expensed as incurred. The Company adopted the provisions of the SOP in its
      financial statements during the third quarter of its current fiscal year
      ending January 31, 1999. The effect of adoption of SOP 98-5 was to record
      a one-time charge of the cumulative effect of changes in accounting of
      $473,000 ($0.06 per basic share and $0.05 per diluted share) net of taxes
      to expense all start-up costs. $95,000 ($0.01 per basic and diluted share)
      in start-up costs will be retroactively expensed in the first quarter of
      the current fiscal year and the remaining $378,000 ($0.05 per basic share
      and $0.04 per diluted share) is expensed in the third quarter of the
      current fiscal year.

4.    Income Taxes

      Income taxes for the interim periods are computed using the effective tax
      rates estimated to be applicable for the full fiscal year based on the
      provision accrued for the Company's year ended January 31, 1998. However
      the combined tax provision is less than the expected statutory rate as
      XXCAL had elected to be taxed as an S Corporation for the period preceding
      the merger.

5.    New Accounting Standards

      In 1997, the Financial Accounting Standards Board issued Statement No.128,
      "Earnings Per Share". The statement replaced the calculation of primary
      and fully diluted earnings per share with basic and diluted earnings per
      share. Unlike primary earnings per share, basic earnings per share
      excludes any dilutive effects of options, warrants and convertible
      securities. Diluted earnings per share is very similar to the previously
      reported fully diluted earnings per share. All earnings per share amounts
      for all periods have been presented, and where appropriate, restated to
      conform to the statement's requirements.

      As of February 1, 1998, the Company adopted Statement 130, Reporting
      Comprehensive Income. Statement 130 establishes new rules for the
      reporting and display of comprehensive income and its components; however,
      the adoption of this Statement had no impact on the Company's net income
      or shareholders' equity. Statement 130 requires display of unrealized
      gains or losses on available-for-sale securities and foreign currency
      translation adjustments. The Company does not have these accounting
      transactions. Prior year financial statements have not been reclassified
      to conform to the requirements of statement 130 since there is no impact.

6.    Inventories

      Inventories consist of accumulated costs applicable to uncompleted
      contracts and are stated at actual cost which is not in excess of
      estimated net realizable value.

<PAGE>


7.    Interest and Taxes

      Cash paid for interest and taxes for the nine months ended October 31,1998
      was $951,000 and $1,116,000 respectively. Cash paid for interest and taxes
      for the nine months ended July 31, 1997 was $907,000 and $944,000
      respectively.

8.    Minority Interest

      Minority interest in the Company's NQA-USA, Inc. subsidiary is a result of
      50% of the stock of NQA-USA, Inc. being issued to National Quality
      Assurance, Ltd. Profits and losses are allocated 63% to NTS, Inc. and 37%
      to National Quality Assurance, Ltd for the fiscal year ending January 31,
      1999.

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

Except for the historical information contained herein, the matters
addressed in this Item 2 contain forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995. Such statements can be
identified by the use of forward-looking words such as "may", "will",
"expect", "anticipate", "intend", "estimate", "continue", "behave" and similar
words. Financial information contained herein, to the extent it is predictive of
financial condition and results of operations that would have occurred on the
basis of certain stated assumptions, may also be characterized as
forward-looking statements. Although forward-looking statements are based on
assumptions made, and information believed by management to be reasonable, no
assurance can be given that such statements will prove to be correct. Such
statements are subject to certain risks, uncertainties and assumptions. Should
one or more of these risks or uncertainties occur, or should underlying
assumptions prove incorrect, actual results may vary materially from those
anticipated.

GENERAL

On October 30, 1998, the Company completed its merger with XXCAL. The
transaction was treated as a pooling of interests whereby NTS issued to the
shareholders of XXCAL 1,297,878 shares of NTS common stock constituting 15.6% of
the outstanding common stock of NTS after giving effect to the merger. NTS has
also reserved an additional 214,622 shares of its common stock for issuance upon
exercise of outstanding XXCAL, Inc. stock options that were assumed by the
Company.

XXCAL is principally engaged in outsourcing personnel for a wide variety of
temporary technical and professional positions into the information technology
and information systems industries including compatibility testing of hardware
and software components. XXCAL has approximately 300 employees and has offices
in Los Angeles, San Francisco, San Jose, Austin, Houston, London, England and
Yokohama, Japan.

The statements presented as of and for the nine-month and three-month periods
ended October 31, 1998 and 1997 are unaudited and are presented based on the
"pooling of interests" method of accounting pursuant to Opinion No. 16 of the
Accounting Principles Board. They include the combined financial statements of
NTS and XXCAL from the beginning of the fiscal year. All prior year financial
statements have also been restated to reflect the pooling of interests method of
accounting.

The consolidated balance sheets presented herein for the prior year are as of
January 31, 1998 for NTS and December 31, 1997 for XXCAL. The consolidated
statements of income and operations presented herein for the prior year are for
the nine months and three months ended October 31, 1997 for NTS and nine months
and three months ended September 30, 1997 for XXCAL. The consolidated statements
of cash flows presented herein for the prior year are for the nine months ended
October 31, 1997 for NTS and nine months ended September 30, 1997 for XXCAL. All
financial statements presented herein for the current year are as of and for the
nine and three months ended October 31, 1998 for both entities.

The Company has reorganized itself into two major operational groups: 1) The
Evaluation and Engineering Group which includes all the Technical Services
testing facilities and the Certification Services unit. 2) The IT Solutions
Group which combines XXCAL with the NTS Technical Staffing and Registration
businesses. Each group is under the direction of its own executive management
team. Accordingly, the Company's segment reporting has been changed to reflect
this new structure.

The following discussion should be read in conjunction with the consolidated
quarterly financial statements and notes thereto. All information is based upon
operating results of National Technical Systems, Inc. for the nine months ended
October 31.

                               ===========            ============

For the nine months ended October 31, 1998, consolidated revenues increased by
$7,520,000 or 12.4% when compared to the same period in 1997.

Evaluation & Engineering:
- -------------------------
In 1998, the Evaluation and Engineering segment revenues increased by $1,273,000
primarily due to the additional revenues generated from two new testing
facilities added during 1997. This increase was partially offset by decreases in
the revenues generated by some of the facilities which have experienced a
slowdown in their production activities as some programs are reaching maturity
and as some of the newer research and development programs being conducted by
the Company's clients are experiencing difficulties producing new products due

                                       10
                                 Page 10 of 41
<PAGE>
to technological problems thus delaying production of hardware for evaluation
and testing.

IT Solutions:
- -------------
Revenues in the IT Solutions segment increased by $6,247,000 or 21.6% due to
increases in fee placements in the IT portion of its business, the continuing
success of its strategic alliances with Fortune 500 companies and other major
technical staffing companies, an aggressive expansion into new markets in the IT
business and an increase in registration revenues due to increased demand by
U.S. companies for ISO 9000 certification. The Company has increased its efforts
in the permanent placement market due to customer demand and has enjoyed growth
in that area. Because of the Asian economic decline, several key programs in the
hardware and software compatibility testing area have been delayed or canceled.
This has particularly affected the growth of the revenues from the Japanese
market. In order to mitigate this downturn, the Company is now 52% owner in a
Japanese company based in Yokohama. This will allow Japanese customers to work
directly with our Company in Japan thus reducing their export costs and the
delays associated with exporting.

GROSS PROFIT
Nine months ended October 31          1998   % Change         1997

  % to segment revenue               26.2%                   27.5%

 % to total net revenue              28.8%                   29.0%

Total gross profit for the nine-month period ended October 31, 1998 increased by
$2,066,000 or 11.8% when compared to 1997 primarily as a result of increased
revenues in the IT Solutions Group.

Evaluation & Engineering:
- -------------------------
Gross profit for the Evaluation and Engineering Group slightly decreased as a
result of the slowdown in revenues and competitive pressures which had an
adverse effect on margins. The slowdown in revenues was partially due to the
delays in the production of hardware for evaluation and testing discussed above,
while some of the labor costs remained constant and thus had an adverse effect
on margins. In addition, government laboratories are becoming more aggressive in
competing with private industry for programs, thus increasing the pressure on
profits.

IT Solutions:
- -------------
Gross profit as a percentage of net revenues in 1998 increased by $2,155,000 or
24.3% in the IT Solutions Group when compared to the same period in 1997 due to
the continued growth in this segment of the business and the success in
obtaining more permanent placement contracts. However, the slowdown in revenues
from the Japanese market discussed above had an adverse impact on profits.

Total selling, general and administrative expenses increased $2,260,000 or 18.4%
for the nine-month period ended October 31, 1998 when compared to the same
period in 1997.

Evaluation & Engineering:
- -------------------------
The increase in the Evaluation and Engineering segment was due to efforts to
expand the base of business into new technological areas by engaging specialists
in these new areas to offset the relatively flat growth in the basic testing
business. The Company is redirecting some of its sales efforts to procure larger
evaluation programs which require a greater depth of technical knowledge. Thus
the Company has hired a number of such specialists which has caused selling
expenses to increase in advance of achieving results from their work.

IT Solutions:
- -------------
The increase in the IT Solutions segment was due primarily to costs related to
the planned expansion of the sales and marketing capabilities through new
marketing programs and expansion efforts in new markets.

The Company continues to look for new ways to reduce costs yet remain effective
in all segments of its business.


MERGER COSTS

Merger Costs                          $906        N/A         $0

During the nine months period ended October 31, 1998, the Company incurred
$906,000 in one-time costs related to the merger with XXCAL. These costs are
related to outside consulting, accounting, legal fees and other fees and
expenses specifically associated with the merger and in accordance with APB 16,
they were expensed as incurred.

INTEREST EXPENSE

Net interest expense decreased $40,000 in the nine months ended October 31,
1998, when compared to the same period in 1997. This decrease was principally
due to lower interest rates offset by slightly higher average debt balances.

INCOME TAXES

The income tax provisional rate for the first nine months of 1998 (40.6%) and
1997 (37.6%) reflects a rate in excess of the U.S. federal statutory rate
primarily due to the inclusion of state income taxes. The estimate for fiscal
year ending January 31, 1999 is based on the actual provision accrued for fiscal
year ended January 31, 1998 and XXCAL's projected income tax rate which is lower
since it had elected to be taxed as an S Corporation for the period preceding
the merger. Additional adjustments were made to the current year provision to
account for the non-deductibility for tax purposes of certain merger costs.
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 evaluate the realizability of the
deferred tax asset quarterly by assessing the need for a valuation account based
upon future net income of the Company.

START-UP EXPENSES

In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5, "Reporting the Costs of Start-Up activities", which
requires that costs related to start-up activities be expensed as incurred. The
Company adopted the provisions of the SOP in its financial statements during the
quarter ended October 31, 1998 which resulted in a one-time charge of $473,000
net of taxes in start-up related expenses. (See note 3)

NET INCOME

The decrease in net income for the nine months ended October 31, 1998, compared
to the same period in 1997, was primarily due to the one-time merger costs and
start-up expenses discussed above. In addition, the Company experienced higher
selling, general and administrative expenses, offset partially by higher gross
profit margins due to increased revenues.

YEAR 2000

The Company has assessed and identified to the best of its knowledge all
requirements needed to fix potential problems related to the Year 2000 issue.
This includes: (1) the Company's business software and hardware at all its
locations, (2) the Company's test equipment used in all the laboratories and (3)
communications with third party vendors to ensure they will meet their Year 2000
requirements.

Much of the hardware used by the Company has already been upgraded to become
Year 2000 compliant or will become compliant by March 31, 1999. Certain test
equipment at the laboratories has been identified to be date sensitive and
vendors are supplying new Year 2000 compliant software. In situations where the
software is not available, the Company is replacing the equipment. To complete
the necessary remediation of its business systems software, the Company has
identified new Year 2000 compliant software that will replace certain crucial
software applications it currently uses. All other identified existing systems
will be fixed internally. The Company expects to complete its software
remediation by June 30, 1999.

                                       13
                                 Page 13 of 41
<PAGE>


The estimated total cost for the Year 2000 project is approximately $400,000 for
new hardware, software and in-house programming. The Company does not expect
these costs to have a material impact on the Company's financial position,
results of operations or cash flows.

The Company has also contacted its major third-party vendors and is in the
process of obtaining assurances that their systems are Year 2000 compliant.
Although the Company does not anticipate any material problems resulting from
the Year 2000 issues, it is taking steps to establish a contingency plan in the
event of system failures beyond the Company's control or in the event of failure
by other companies or governmental entities to remediate their own systems.

The following information is based upon results for National Technical Systems,
Inc. for the three months ended October 31.

                                 =========              ==========

For the three months ended October 31, 1998, consolidated revenues increased by
$1,787,000 or 8.3% when compared to the same period in 1997.

Evaluation & Engineering:
- -------------------------
Revenues in the Evaluation and Engineering segment decreased $285,000 primarily
due to decreases in the revenues generated by some of the facilities which have
experienced a slowdown in their production activities as some programs are
reaching maturity and as some of the newer research and development programs
being conducted by the Company's clients are experiencing difficulties producing
new products due to technological problems thus delaying production of hardware
for evaluation and testing. This decrease was partially offset by revenues from
a new test facility opened during the fourth quarter of last year.

IT Solutions:
- -------------
Revenues in the IT Solutions segment increased $2,072,000 or 19.8% due to
increases in fee placements in the IT portion of its business, the continuing
success of its strategic alliances with Fortune 500 companies and other major
technical staffing companies, the expansion into new markets and an increase in
registration revenues due to increased demand by U.S. companies for ISO 9000
certification. The Company has increased its efforts in the permanent placement
market due to customer demand and has enjoyed growth in that area. Because of
the Asian economic decline, several key programs in the hardware and software
compatibility testing area have been delayed or canceled. This has particularly

                                       14
                                 Page 14 of 41
<PAGE>


affected the growth of the revenues from the Japanese market. In order to
mitigate this downturn, the Company is now 52% owner in a Japanese company based
in Yokohama. This will allow Japanese customers to work directly with our
Company in Japan thus reducing their export costs and the delays associated with
exporting.

 % to total revenues                 28.5%                   29.5%

Total gross profit for the three months ended October 31, 1998 increased by
$304,000 or 4.8% primarily as a result of increased revenues in the IT Solutions
Group which carry a higher gross margin.

Evaluation & Engineering:
- -------------------------
Gross profit for the Evaluation and Engineering Group decreased as a result of
the slowdown in revenues and competitive pressures which had an adverse effect
on margins. The slowdown in revenues was partially due to the delays in the
production of hardware for evaluation and testing discussed above, while some of
the labor costs remained constant and thus had an adverse effect on margins. In
addition, government laboratories are becoming more aggressive in competing with
private industry for programs, thus increasing the pressure on profits.

IT Solutions:
- ------------
Gross profit as a percentage of net revenues in 1998 increased 24.3% in the IT
Solutions Group when compared to the same period in 1997 due to the continued
growth in this segment of the business and the success in obtaining more
permanent placement contracts. However, the slowdown in revenues from the
Japanese market discussed above had an adverse impact on profits.

Merger Costs                          $545        N/A           $0

During the three months period ended October 31, 1998, the Company incurred
$545,000 in one-time costs related to the merger with XXCAL. These costs are
related to outside consulting, accounting, legal fees and other fees and
expenses specifically associated with the merger and in accordance with APB 16,
they were expensed as incurred.

INTEREST EXPENSE

Net interest expense decreased $27,000 in the quarter ended October 31, 1998,
when compared to the same period in 1997. This decrease was principally due to
lower interest rates offset by slightly higher average debt balances.

INCOME TAXES

realized on the basis of offsetting it against deferred tax liabilities. It is
the Company's intention to evaluate the realizability of the deferred tax asset

requires that costs related to start-up activities be expensed as incurred. The
Company adopted the provisions of the SOP in its financial statements during the
quarter ended October 31, 1998 which resulted in a one-time charge of $378,000
net of taxes in start-up related expenses during the third quarter of the
current fiscal year. $95,000 in start-up costs will be retroactively expensed in
the first quarter of the current fiscal year. (See note 3)

NET INCOME (LOSS)

The decrease in net income (loss) for the three months ended October 31, 1998,
compared to the same period in 1997, was primarily due to the one-time merger
costs and start-up expenses discussed above. In addition, the Company
experienced higher selling, general and administrative expenses, offset
partially by higher gross profit margins due to increased revenues.

BUSINESS ENVIRONMENT

Evaluation & Engineering:
- -------------------------
The business climate which has in the past shown signs of uncertainty and which
had appeared to stabilize last year, has again become uncertain. This has
occurred due to program delays in new research and development projects caused
by technical difficulties being experienced by the Company's clients. In
addition, the trend to outsourcing, which started when many contractors began
downsizing, has begun to reverse. Some are now keeping programs in-house. Also,
government laboratories are becoming more aggressive in competing with private
industry for programs. All these factors have rendered the market more
competitive with an attendant pressure on profits.

IT Solutions:
- -------------
The Company has aggressively pursued additional business in the growing IT
market. The Company supplies IT professionals in support of customers who need
help-desk analysts and managers; relational database administrators and
developers; application and systems programmers; configuration and project
managers; and multiple levels of system operations personnel. The Company
believes the growth in this sector will be accompanied by higher margins and
contribute favorably to the overall product mix. Also, the Company continues to
pursue ISO registration business as demand for these services continues to
increase as more companies must compete for business in the global market place.

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, 1998, cash provided by operations
increased by $1,189,000 when compared to the same period in 1997. Major items
contributing to this increase were increases in accrued expenses, depreciation
and amortization and the effect of changes in accounts payable and inventories
partially offset by a decrease in net income and income taxes.

Net cash used in investing activities in the nine-month period ended October 31,
1998 decreased $684,000 over the same period in 1997 due to reduced capital
requirements for fiscal year 1999 as compared to fiscal year 1998. The actual
level of capital spending will be dependent on a variety of factors, including
general economic conditions, bank covenants and the Company's operating
requirements.

In the nine-month period ended October 31, 1998, net cash used for financing
activities consisted of debt reduction on lines of credit and short term and
long term debt of $4,689,000 and cash dividends paid of $488,000 and
distributions of $362,000 offset by increases in lines of credit and term loans
of $4,743,000 and proceeds from issuance of common stock of $176,000. In
September 1997, the Company negotiated with Sanwa Bank California as agent and
Mellon Bank for a new credit agreement which includes a $6,000,000 revolving
line of credit at an interest rate equal to the Bank's reference rate plus 0.25%
which expires in September 1999. Also included in the new agreements is a
$6,500,000 term loan at an interest rate of 8.31% which expires in January 2003.
On October 30, 1998, the credit agreement was amended: 1) to extend the term of
the revolving line to September 8, 2000 2) to increase the revolving line amount
from $6,000,000 to $8,000,000 at an interest rate equal to the Bank's reference
rate and 3) to add a new term loan for $2,000,000 at an interest rate equal to
the Bank's reference rate plus 0.25% and a maturity date of November 1, 2003.

Management is not aware of any significant demands for capital funds that may
materially affect the short or long-term liquidity in the form of large fixed
asset acquisitions, unusual working capital commitments or contingent
liabilities. In addition, the Company has made no material commitments for
capital expenditures. The Company's future working capital will be provided from
operations and the current bank revolving line of credit which had $4,100,000
available at October 31, 1998.

limitations. The arbitrators will have the authority to decide whether any such
claim or controversy is barred by the statute of limitations and, if so, to
dismiss the arbitration on that basis.

may be submitted to any authorized court of law to be confirmed and enforced.

                              (B) additional or supplementary remedies.

                  (8) The pursuit of or successful action for interim,
additional or supplementary remedies, or the filing of a court action, does not
constitute a waiver of the right of the Borrower, the Agent or any Lender or the
L/C Bank, including the suing party, to submit the controversy or claim to
arbitration if the other party contests the lawsuit.
