                                48500 KATO ROAD
                           FREMONT, CALIFORNIA 94538
 
Dear DSPT Stockholder:
 
    You are cordially invited to attend a special meeting of the stockholders of
DSP Technology Inc. on Friday, May 28, 1999 at the offices of DSPT located at
48500 Kato Road, Fremont, California, at 2:00 p.m., local time. At the special
meeting, you will be asked to vote on a proposal to approve the merger agreement
among DSPT, MTS Systems Corporation and Badger Merger Corp., a wholly-owned
subsidiary of MTS. As a result of the merger, DSPT will become a wholly-owned
subsidiary of MTS and you will become a shareholder of MTS.
 
    The merger will combine MTS' global presence in computer-based mechanical
design and system integration skills with DSPT's expertise in state-of-the-art
software, data acquisition and control systems.
 
    Upon the closing of the merger, the holders of the outstanding shares of
DSPT common stock and outstanding options to purchase DSPT common stock will
receive a total of 2,077,000 shares of MTS common stock. As a result, each
outstanding DSPT share and each net option share represented by outstanding DSPT
options will be exchanged for a fraction, the exchange ratio, of a share of MTS
common stock. The exchange ratio will be determined at closing by dividing the
2,077,000 MTS common shares to be issued in the merger by the sum of the total
number of DSPT shares outstanding plus the net option shares, calculated as
follows:
 
    - DSPT's net option shares will represent DSPT shares issuable upon exercise
      of outstanding options less a number of DSPT shares with a value, based
      upon the implied DSPT share value at closing, equal to the aggregate
      exercise price of such options.
 
    - The implied DSPT share value at closing will be determined by dividing the
      market value of the MTS shares issued in the merger plus the aggregate
      exercise price of the DSPT options by the total number of DSPT shares
      outstanding and subject to outstanding options.
 
    For example, based on an assumed price of $13.00 for MTS common stock at the
closing of the merger and assuming all currently outstanding stock options
remain unexercised at the time of closing, each of DSPT's common shares and each
of its net option shares would receive approximately 0.8037 of a share of MTS
common stock. The actual exchange ratio will be determined at closing.
 
    The exact exchange ratio will depend upon the market price of MTS common
stock, the number of outstanding shares of DSPT common stock, the number of DSPT
shares subject to outstanding options and the exercise prices of such options.
Therefore, the actual exchange ratio for the merger, the aggregate value of the
2,077,000 MTS shares of common stock issued in the merger, and the allocation of
the aggregate merger consideration between DSPT stockholders and optionholders
could be affected by:
 
    - increases or decreases in the market price of MTS common stock;
 
    - exercises of DSPT options and their related exercise prices; and
 
    - grants of additional DSPT options.
 
    MTS common stock is traded on the Nasdaq National Market under the symbol
"MTSC." DSPT common stock is traded on the Nasdaq National Market under the
symbol "DSPT." DSPT stockholders
<PAGE>
should obtain recent market quotations for MTS common stock and DSPT common
stock and understand the exchange ratio being offered in the merger.
 
    If you would like information regarding the exchange ratio and, if you hold
options, the implied DSPT share value used to determine the number of net option
shares represented by your options, you may call DSPT's proxy solicitor,
MacKenzie Partners, Inc., at (800) 322-2885. MacKenzie Partners will provide to
you an estimate of the exchange ratio and the implied DSPT share value as of any
date prior to and including the date on which the exchange ratio is finally
determined. MacKenzie Partners will also provide instructions on how to submit
proxies in a timely manner, including instructions if you wish to wait until the
exchange ratio is finally determined before voting. If you wish to change your
vote, you may do so by transmitting the request by facsimile to MacKenzie
Partners at (212) 929-0308 or by attending the special meeting.
 
    DSPT'S BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS FAIR TO YOU AND IN
YOUR BEST INTERESTS. THE BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
THE MERGER AND RECOMMENDS THAT YOU VOTE TO APPROVE THE MERGER AGREEMENT AND THE
MERGER.
 
    Because of the significance of the merger, your participation in the special
meeting, either in person or by proxy, is especially important. We hope you will
be able to attend the special meeting. However, even if you anticipate attending
in person, we urge you to mark, sign and return the enclosed proxy card promptly
in the enclosed postage-paid envelope to ensure that your shares of common stock
will be represented at the special meeting. If you do attend, you will, of
course, be able to vote your shares in person.
 
    Thank you, and we look forward to seeing you at the special meeting.

THE COMPANIES
 
MTS Systems Corporation (SEE PAGE 1)
14000 Technology Drive
Eden Prairie, MN 55344-2290
(612) 937-4000
 
    Organized in 1966, MTS is a technology-based company providing engineering
services, equipment and software for applications in materials and product
research, product development, quality control and factory automation.
 
    MTS bases its business on a set of building-block technologies and business
processes. Technologies include sensors for measuring machine and process
parameters, control technologies for test and process automation, hydraulic and
electric servodrives for precise actuation, and application software to tailor
the test or automation system to the customer's needs and to analyze results.
Business processes include project and product styles of operations on a
worldwide basis. In combination, they offer solutions to customers in a variety
of markets.
 
    MTS' operations are organized into two business sectors: (1) mechanical
testing and simulation, and (2) factory automation. In the mechanical testing
and simulation sector, customers use MTS' products and services in research,
product development and quality control to determine the mechanical properties
and performance of materials, products and structures. Many of MTS' products and
services support customers' mechanical design automation processes. In the
factory automation sector, customers use MTS' measurement and control
instrumentation to measure process variables and to automate production
processes. The operational alignment of the mechanical testing and simulation
and factory automation sectors allows MTS to maintain a strategic focus on
markets with different applications of its technologies and with different
competitors.
 
                                       3
<PAGE>
DSP Technology Inc. (SEE PAGE 49)
48500 Kato Road
Fremont, CA 94538
(510) 657-7555
 
    DSPT designs, develops, manufactures, markets and integrates high-speed
computer-automated instrumentation for measurement and control applications.
DSPT has two divisions, the transportation group, which focuses on powertrain
testing, and the lab group, which focuses on vehicle safety and component
testing, general data acquisition and signal analysis. Powertrain testing is
currently DSPT's largest market and major focus.
 
EXCHANGE RATIO (SEE PAGE 40)
 
    The exchange ratio will be determined at closing by dividing the 2,077,000
MTS common shares to be issued in the merger by the sum of the total number of
shares of DSPT common stock outstanding plus the net option shares represented
by outstanding DSPT stock options, calculated as follows:
 
    - DSPT's net option shares will represent DSPT shares issuable upon exercise
      of outstanding options less a number of DSPT shares with a value, based
      upon the implied DSPT share value at closing, equal to the aggregate
      exercise price of such options.
 
    - The implied DSPT share value at closing will be determined by dividing the
      market value of the MTS common shares issued in the merger plus the
      aggregate exercise price of the DSPT options by the total number of DSPT
      shares outstanding and subject to outstanding options.
 
    For example, based on an assumed price of $13.00 for MTS common stock at the
closing of the merger and assuming all currently outstanding stock options
remain unexercised at the time of closing, each of DSPT's common shares and each
of its net option shares would receive approximately 0.8037 of a share of MTS
common stock.
 
    The exact exchange ratio will be determined at closing and will depend upon
the market price of MTS common stock, the number of outstanding shares of DSPT
stock, the number of DSPT shares subject to outstanding options and the exercise
prices of such options. Therefore, the actual exchange ratio for the merger, the
aggregate value of the 2,077,000 MTS shares issued in the merger, and the
allocation of the aggregate merger consideration between DSPT stockholders and
optionholders could be affected by:
 
    - increases or decreases in the market price of MTS common stock;
 
    - exercises of DSPT options and their related exercise prices; and
 
    - grants of additional DSPT options.
 
    DSPT has agreed in the merger agreement that it will not grant options for
more than 28,000 shares prior to the closing of the merger.
 
OWNERSHIP OF MTS FOLLOWING THE MERGER
 
    DSPT stockholders and optionholders will receive a total of 2,077,000 shares
of MTS common stock in the merger. Based on the number of shares of MTS common
stock outstanding on April 1, 1999, existing DSPT stockholders and optionholders
will own approximately 10% of MTS common stock after the merger.
 
                                       4
<PAGE>
REASONS FOR THE MERGER (SEE PAGE 27)
 
    MTS.  The board of directors of MTS approved the merger based on a number of
factors including, among other things, the following:
 
    - the merger will further MTS' commitment to customers to provide a broader
      and more integrated analysis, simulation and testing process that will
      enable customers to lower development costs and move products to market
      faster;
 
    - DSPT has unique expertise, technologies and customer recognition in the
      market for test, analysis and validation of engine designs; and
 
    - the combined firms would be a stronger force in the global powertrain
      testing market because they complement each other in technology, customer
      base and geographic presence.
 
    DSPT.  The board of directors of DSPT believes that the merger should result
in a number of benefits to DSPT and its stockholders including, among other
benefits, the following:
 
    - the potential to obtain contracts for larger system integration projects
      due to the lower perceived risk to customers as a result of the larger
      relative size of the combined company compared to DSPT;
 
    - the potential for increased sales to MTS' powertrain unit customers,
      primarily as a result of combining the product lines of the powertrain
      unit and DSPT to offer diesel customers broader test capabilities and
      complementary product lines;
 
    - the potential for increased sales of DSPT products to MTS powertrain
      component test product customers;
 
    - the opportunity for increased DSPT international sales, leveraging MTS'
      international business;
 
    - the potential for increased sales in the powertrain testing market as a
      result of integrating MTS' noise and vibration capability into DSPT
      products; and
 
    - the greater liquidity and diversification of risk offered to DSPT
      stockholders by an investment in MTS instead of DSPT.
 
DSPT'S RECOMMENDATION TO YOU (SEE PAGE 30)
 
    The DSPT board of directors believes that the merger is fair to you and in
your best interests. The DSPT board of directors unanimously recommends that you
vote "FOR" adoption of the merger agreement and approval of the merger.
 
THE SPECIAL MEETING (SEE PAGE 19)
 
    A special meeting of the stockholders of DSPT will be held on May 28, 1999,
at the offices of DSPT located at 48500 Kato Road, Fremont, California at 2:00
p.m. local time to consider and vote upon a proposal to adopt the merger
agreement and to approve the merger.
 
RECORD DATE AND VOTING POWER (SEE PAGE 19)
 
    You are entitled to vote at the special meeting if you owned shares of DSPT
common stock on the close of business on April 15, 1999, the record date for the
special meeting. You will have one vote at the special meeting for each share of
DSPT common stock you owned on the record date. DSPT optionholders will not be
entitled to vote at the special meeting. There are 2,351,076 shares of DSPT
common stock entitled to be voted at the special meeting.
 
                                       5
<PAGE>
REQUIRED VOTE (SEE PAGE 19)
 
    The adoption of the merger agreement and approval of the merger requires the
affirmative vote of a majority of the shares of DSPT common stock outstanding on
the record date.
 
SHARE OWNERSHIP OF MANAGEMENT AND CERTAIN STOCKHOLDERS (SEE PAGE 66)
 
    The directors and executive officers of DSPT own approximately 8.1% of the
shares entitled to vote at the special meeting. All of them have agreed to vote
their shares for the adoption of the merger agreement and approval of the
merger.
 
EXCHANGE OF STOCK CERTIFICATES (SEE PAGE 20)
 
    If you are a DSPT stockholder, you should not send in your stock
certificates now. After the merger is completed, MTS will send DSPT stockholders
and optionholders written instructions for receiving shares of MTS common stock
in exchange for their stock certificates and options. MTS shareholders will keep
their current certificates, and will continue to hold the same number of shares
of MTS common stock after the merger.
 
INTERESTS OF DSPT'S OFFICERS AND DIRECTORS IN THE MERGER (SEE PAGE 35)
 
    You should be aware that a number of DSPT's officers and directors have
employment contracts, stock options and severance packages that give them
interests in the merger that are different from other DSPT stockholders. In
addition, MTS will cause indemnification and insurance arrangements to be
maintained for the DSPT officers and directors.
 
COMPARATIVE PER COMMON SHARE MARKET PRICE INFORMATION (SEE PAGE 17)
 
    MTS common stock is traded on the Nasdaq National Market under the symbol
"MTSC." On March 23, 1999, the last trading day before the announcement that MTS
and DSPT entered into the merger agreement, the closing sale price of MTS common
stock was reported at $10.313 per share. Following the merger, MTS common stock
will continue to be traded on the Nasdaq National Market under the symbol
"MTSC." On April 27, 1999, the closing sale price of MTS common stock was
reported at $11.50.
 
    DSPT common stock is traded on the Nasdaq National Market under the symbol
"DSPT." On March 23, 1999, the last trading day before the announcement that MTS
and DSPT entered into the merger agreement, the closing sale price of DSPT
common stock was reported at $5.75 per share. On April 27, 1999, the closing
sale price of DSPT common stock was reported at $7.625. Following the merger,
DSPT common stock will cease to be traded on the Nasdaq National Market because
all of the outstanding shares of DSPT common stock will be converted into MTS
common stock.
 
TAX MATTERS (SEE PAGE 37)
 
    The exchange of shares of DSPT common stock for shares of MTS common stock
in the merger will be tax-free to you for federal income tax purposes. You will,
however, have to pay taxes with respect to any cash received for any fractional
share. Your tax basis in the shares of MTS common stock that you will receive in
the merger will equal your current tax basis in your DSPT common stock. However,
your tax basis will be reduced by the basis allocated to any fractional share
interest for which you receive cash.
 
TREATMENT OF OPTIONS (SEE PAGE 36)
 
    In the merger, unexercised options representing "net option shares" will be
exchanged for MTS common stock. DSPT intends to treat the conversion of
incentive stock options into MTS common stock as a deemed exercise of the
incentive stock options, resulting in income recognition for U.S. federal
alternative minimum tax purposes, but not for federal regular income tax
purposes. Withholding
 
                                       6
<PAGE>
taxes will not be withheld with respect to the conversion of incentive stock
options into MTS common stock.
 
    Holders of nonqualified stock options to acquire DSPT common stock who have
their unexercised options converted into MTS common stock will recognize
ordinary income for income tax purposes which will be reported on their 1999
Form W-2 (for employees) or Form 1099 (for former employees and independent
contractors), in an amount equal to the value of the MTS common stock on the
merger closing date. Withholding taxes will apply with respect to wage income
recognized by employees and former employees.
 
    TAX MATTERS CAN BE COMPLICATED, AND THE TAX CONSEQUENCES OF THE MERGER TO
YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR OWN
TAX ADVISORS TO FULLY UNDERSTAND THE TAX CONSEQUENCES OF THE MERGER TO YOU.
 
ANTICIPATED ACCOUNTING TREATMENT (SEE PAGE 39)
 
    The merger is expected to be accounted for as a "pooling of interests" for
financial accounting purposes.
 
FAIRNESS OPINION OF FINANCIAL ADVISOR (SEE PAGE 31)
 
    In deciding to approve the merger, DSPT's board of directors considered the
opinion of its financial advisor as to the fairness of the merger to you from a
financial point of view. This opinion is attached as Appendix B to this proxy
statement/prospectus. We encourage you to read this opinion carefully.
 
    DSPT's financial advisor performed several analyses in connection with
delivering its opinion. These analyses included comparing DSPT's and MTS'
historical stock prices, comparing DSPT and MTS to other publicly-traded
companies, and estimating the relative values and contributions of DSPT and MTS
based on past performance.
 
REGULATORY REQUIREMENTS (SEE PAGE 39)
 
    We are prohibited by U.S. antitrust laws from completing the merger until
after we have furnished revenue and market information and materials to the
Antitrust Division of the Department of Justice and the Federal Trade Commission
and a required waiting period has ended. MTS and DSPT have each filed the
required notification and report forms with the Department of Justice and the
Federal Trade Commission, and the waiting period for those filings has not yet
expired. In letters dated April 20, 1999, the U.S. Department of Justice
requested that MTS and DSPT voluntarily supply information concerning the
merger. Both parties have supplied some of the requested information and expect
to supply further information on a voluntary basis. Assuming the Department of
Justice does not extend the waiting period, it will expire on May 6, 1999. After
the waiting period expires, the Department of Justice and the Federal Trade
Commission continue to have the authority to challenge the merger on antitrust
grounds before or after the merger is completed.
 
NO APPRAISAL RIGHTS (SEE PAGE 39)
 
    DSPT is organized under Delaware law. Under Delaware law, stockholders of
DSPT have no rights to an appraisal of the value of their shares in connection
with the merger.
 
CONDITIONS TO THE MERGER (SEE PAGE 41)
 
    MTS and DSPT will not complete the merger unless several conditions are
satisfied or waived, including the following:
 
    - the adoption of the merger agreement and approval of the merger by the
      DSPT stockholders;
 
                                       7
<PAGE>
    - the absence of any legal action making the merger illegal or prohibiting
      the merger or that would materially limit the ability of MTS to own and
      operate the assets and business of DSPT;
 
    - the receipt of all material approvals and consents of third parties
      necessary to consummate the merger;
 
    - the receipt of all permits or other authorizations required by applicable
      state securities laws for the MTS common stock to be issued in connection
      with the merger;
 
    - the expiration or termination of the applicable waiting period under
      antitrust laws;
 
    - the compliance by MTS and DSPT with their obligations under the merger
      agreement and the representations and warranties made by MTS and DSPT,
      respectively, in the merger agreement being true in all material respects;
 
    - the delivery by counsel for each company of its tax and legal opinions to
      the other company; and
 
    - the delivery by the accounting firm for MTS of a letter stating that the
      firm concurs with MTS management's conclusion that the merger may be
      accounted for as a pooling of interests and delivery by the accounting
      firm for DSPT of a letter stating that the firm is not aware of any fact
      concerning DSPT that would preclude the merger from being treated as a
      pooling of interests for financial accounting purposes.
 
LIMITATION ON DISCUSSING OR NEGOTIATING OTHER TRANSACTION PROPOSALS (SEE PAGE
  46)
 
    Subject to certain exceptions, DSPT has agreed not to pursue an alternative
transaction with another party while the merger is pending unless such party has
made a proposal to the DSPT board of directors for a superior transaction with
DSPT.
 
TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 47)
 
    MTS and DSPT can agree by mutual written consent to terminate the merger
agreement at any time, whether before or after the receipt of stockholder
approval. In addition, either company can terminate the merger agreement under
various circumstances, including if:
 
    - the merger is not completed on or before July 31, 1999;
 
    - the merger is prohibited by a final court order;
 
    - the stockholders of DSPT do not vote to approve the merger and adopt the
      merger agreement;
 
    - DSPT breaches its obligation not to pursue a business combination, the
      board of directors recommends an alternative transaction, materially
      modifies in a manner adverse to MTS, or withdraws its recommendation or
      fails to recommend against acceptance of or takes no position regarding a
      third party's tender offer or exchange offer;
 
    - the DSPT board of directors authorizes DSPT to enter into a letter of
      intent or a binding written agreement that constitutes a superior proposal
      to the merger agreement with MTS and MTS does not make at least as
      favorable as the proposal within ten days after notice an offer; or
 
    - either party breaches its representations or obligations under the merger
      agreement, subject to certain exceptions.
 
TERMINATION FEE (SEE PAGE 48)
 
    In connection with the termination of the merger agreement under certain
circumstances, DSPT would be required to pay MTS a termination fee of $400,000.

RISKS RELATING TO THE MERGER
 
INTEGRATING THE TWO BUSINESSES MAY BE DIFFICULT TO ACHIEVE AND THIS MAY
  ADVERSELY AFFECT OPERATIONS
 
    After the merger, MTS and DSPT will have to integrate their operations. In
particular, DSPT's transportation group and MTS' Detroit-based powertrain unit
will be combined in DSPT's Ann Arbor, Michigan facility. The integration will
require significant efforts from each company, including the coordination of
their research and development and sales and marketing efforts. DSPT may find it
difficult to integrate the operations of the powertrain unit. DSPT personnel may
leave DSPT because of the merger. DSPT customers, distributors or suppliers may
terminate their arrangements with DSPT, or demand amended terms to those
arrangements. MTS management, including DSPT management who will become part of
the MTS management team, may have their attention diverted while trying to
integrate the two companies. Such diversion of management's attention or
difficulties in the transition process could have an adverse impact on the
combined operations. If MTS is not able to successfully integrate the operations
of DSPT, MTS' expectations for its future results of operations may not be met.
 
THE COMBINATION MAY FAIL TO ACHIEVE BENEFICIAL SYNERGIES
 
    Achieving anticipated synergies and the potential benefits underlying the
two companies' reasons for the merger will depend on a number of factors, some
of which include:
 
    - the risk that MTS' and DSPT's customers may defer purchasing decisions
      following the announcement of the merger;
 
    - the risk that it may be more difficult to retain DSPT's key management,
      marketing and technical personnel after the merger;
 
    - the ability of DSPT to timely develop and market new products and product
      enhancements;
 
    - the ability of the combined company to increase sales of DSPT's products;
 
    - the ability of the combined company to increase sales of MTS' products;
 
    - the competitive conditions in the engine and powertrain design and testing
      markets; and
 
    - DSPT's and MTS' completion of their Year 2000 efforts to ensure that the
      products offered to their customers, as well as software, systems and
      products received from suppliers and used internally, are Year 2000
      compliant by December 31, 1999.
 
                                       9
<PAGE>
    There can be no assurance that the anticipated synergies will be achieved.
The failure to achieve such synergies could have a material adverse effect on
the business, results of operations and financial condition of the combined
company.
 
THE EXCHANGE RATIO, THE VALUE OF THE MERGER CONSIDERATION AND THE ALLOCATION OF
  THE MERGER CONSIDERATION BETWEEN DSPT STOCKHOLDERS AND OPTIONHOLDERS WILL
  FLUCTUATE PRIOR TO CLOSING
 
    In the merger, MTS will issue a total of 2,077,000 shares of its common
stock in exchange for all outstanding shares of DSPT common stock and
outstanding options to purchase DSPT common stock. The holders of DSPT common
stock and the holders of options to purchase DSPT common stock will receive a
fraction of a share of MTS common stock, the exchange ratio, which will be
calculated based on the market price of MTS common stock, the number of
outstanding shares of DSPT common stock, the number of DSPT shares subject to
outstanding options and the exercise price of those options. The actual exchange
ratio will not be determined until the closing. Therefore, the actual exchange
ratio for the merger, the aggregate value of the 2,077,000 MTS shares to be
issued in the merger and the allocation of the aggregate merger consideration
between DSPT stockholders and optionholders could also be affected by:
 
    - increases or decreases in the market price of MTS common stock;
 
    - exercises of DSPT options and their related exercise prices; and
 
    - grants of additional DSPT options.
 
    See "Material Terms of the Merger Agreement--Merger Consideration" on page
40.
 
THE COSTS OF COMPLETING THE MERGER ARE SUBSTANTIAL AND MAY ADVERSELY AFFECT OUR
  RESULTS OF OPERATIONS
 
    MTS and DSPT estimate that they will incur aggregate, direct transaction
costs of approximately $1,300,000 associated with the merger, which will be
charged to operations in the quarter in which the merger is consummated. This
estimate primarily includes fees for investment bankers, attorneys, accountants,
financial printing and other related charges. In addition, it is expected that
the combined company will incur additional significant charges to operations
after the merger, estimated to be between $200,000 and $300,000 and which have
already been reserved for, to reflect costs of integrating the two companies.
These amounts are only preliminary estimates and are subject to change. Although
MTS expects that the elimination of duplicative expenses as well as other
efficiencies related to the integration of the businesses may offset the direct
transaction and integration expenses over time, it is possible that such a net
benefit will not be achieved in the near term or at all.
 
HOLDERS OF DSPT COMMON STOCK AND OPTIONS WILL HAVE DIFFERENT RIGHTS AS HOLDERS
  OF MTS COMMON STOCK FOLLOWING THE MERGER
 
    Following the merger, holders of DSPT common stock and options to purchase
DSPT common stock outstanding on the date of the merger will become holders of
MTS common stock. Certain differences exist between the rights of DSPT
stockholders under DSPT's certificate of incorporation, as amended, and DSPT's
bylaws and the rights of MTS shareholders under MTS' articles of incorporation,
as amended, and MTS' bylaws. See "Comparison of Rights of Holders of MTS Common
Stock and Holders of DSPT Common Stock" on page 66.
 
RISKS RELATING TO MTS' AND THE COMBINED COMPANY'S BUSINESS
 
MTS' COMMON STOCK PRICE IS EXPECTED TO CONTINUE TO BE VOLATILE
 
    As with most technology stocks, MTS' stock price is based largely on current
expectations of sustained future revenue and earnings growth rates and has been
volatile during the past year. Any failure to meet expected revenue and earnings
levels in any period, or any negative change in perceived
 
                                       10
<PAGE>
growth prospects of MTS after the merger, would likely have a significant
adverse effect on MTS' stock price.
 
MTS' BACKLOG AND QUARTERLY OPERATING RESULTS MAY BE VOLATILE
 
    Possible significant volatility in both backlog and quarterly operating
results for the combined company after the merger may result with respect to
larger, individual fixed price orders currently being pursued by MTS and DSPT.
In addition, delays in realization of backlog orders may occur due to technical
difficulties, inability to obtain export licensing approval or delays in
customers' preparation of installations sites. Any downturn in backlog or timing
of orders would likely have a significant adverse effect on MTS' operating
results and earnings.
 
FAILURE TO ADAPT TO TECHNOLOGICAL CHANGE COULD HAVE AN ADVERSE EFFECT ON MTS'
  REVENUES AND EARNINGS
 
    If MTS is not able to keep pace with technological change in the industries
in which it competes, its revenues and earnings would be adversely effected. MTS
operates in a highly competitive industry characterized by rapid technological
change. MTS' ability to compete effectively and its growth prospects depend upon
many factors, including the success of its existing products and services and
the timely introduction and commercial acceptance of future products and
services, as well as its ability to introduce new products and to enhance its
existing products with features that meet changing end user requirements.
 
EXPORT AND IMPORT CONTROLS COULD HAVE AN ADVERSE EFFECT ON ORDERS FOR MTS
  PRODUCTS
 
    Export controls imposed by the U.S. government and import controls imposed
by foreign governments may cause delays in shipments or rejection of orders by
MTS. Delays or rejection could cause material fluctuations in operating results
and earnings.
 
WEAK ECONOMIC CONDITIONS ABROAD COULD HAVE AN ADVERSE EFFECT ON MTS' RESULTS
 
    MTS' operating and financial results could be significantly adversely
impacted by changes in foreign currency exchange rates and sluggish regional
economic conditions, particularly in Europe and the Pacific Rim.
 
YEAR 2000 PROBLEMS COULD RESULT IN A LOSS OF CUSTOMERS
 
    The impact of Year 2000 issues on future MTS revenues is difficult to
assess, but is a risk that should be considered in evaluating MTS' future growth
potential. MTS believes the current versions of its products are Year 2000
compliant. MTS has been informed by DSPT that current versions of DSPT's
products are Year 2000 compliant. MTS does not intend to make all prior versions
of its products Year 2000 compliant and has notified its customers as to which
versions will and will not be Year 2000 compliant. MTS believes that its
internal information systems are Year 2000 compliant and does not expect
material liabilities or operational difficulties with respect to such systems,
although any material failure of such systems could have a material adverse
effect on MTS' operating results and earnings. See "Information With Respect to
DSPT--Management's Discussion and Analysis of Financial Condition and Results of
Operations" on page 56 and MTS' annual report on Form 10-K for the fiscal year
ended September 30, 1998 incorporated by reference in this proxy
statement/prospectus.
 
DSPT NEEDS TO DEVELOP AND MANAGE ITS SYSTEMS INTEGRATION SERVICES
 
    DSPT believes that the successful marketing and expansion of its
transportation products will be increasingly dependent on its ability to offer
systems integration services. Success depends on DSPT's ability to attract and
retain qualified technical personnel, market acceptance of these services,
timing of service revenues, and the ability to manage customer projects
profitably. The successful management of these projects depends on the timely
availability and quality of key products, the availability of key
 
                                       11
<PAGE>
personnel, the ability to integrate different products from a variety of vendors
effectively, and the management of difficult scheduling and delivery problems.
Most of DSPT's systems integration projects use fixed price contracts. The
pricing of fixed price contracts requires accurate cost estimates in order to be
profitable.
 
DSPT'S QUARTERLY RESULTS HAVE FLUCTUATED SIGNIFICANTLY IN THE PAST AND MAY
  FLUCTUATE SIGNIFICANTLY IN THE FUTURE
 
    DSPT's quarterly operating results have varied significantly depending on a
number of factors. These factors include:
 
    - timing of receipt of system orders from and shipments to major customers;
 
    - variations in product mix and component costs;
 
    - economic conditions prevailing within geographic markets and in the
      worldwide transportation industry;
 
    - market acceptance of new products and services;
 
    - timing and levels of operating expenditures;
 
    - exchange rate fluctuations;
 
    - DSPT's sales being concentrated in only a few customers; and
 
    - DSPT's net sales being sporadic and typically generated in the last month
      of the quarter.
 
DSPT IS HIGHLY DEPENDENT ON ITS SALES OVERSEAS
 
    A significant part of DSPT's revenue growth in the past few years has been
due to increases in DSPT's international sales, particularly in Western Europe
and Asia. International sales accounted for approximately 20%, 35% and 32% of
net sales in fiscals 1999, 1998 and 1997, respectively. DSPT's international
sales are subject to the following risks:
 
    - political and economic changes and disruptions;
 
    - foreign regulation;
 
    - tariffs or other barriers; and
 
    - exchange rate fluctuations.
 
DSPT PURCHASES SEVERAL KEY COMPONENTS FROM LIMITED SOURCES AND SALES COULD BE
  LOST OR DELAYED IF THESE COMPONENTS ARE UNAVAILABLE
 
    DSPT currently purchases several key components used in the manufacture of
its products from a single or limited sources and is dependent on supply from
these sources to meet DSPT's needs. DSPT may encounter shortages and delays in
obtaining such components in the future. Shortages and delays could have an
adverse effect on DSPT's ability to meet customer orders and could result in
lost or delayed sales and revenues.

    The following table sets forth the closing per share sales price of MTS
common stock and DSPT common stock, as reported on Nasdaq, and the estimated
equivalent per share price, as explained below, of DSPT common stock on March
23, 1999, the last trading day before the public announcement of the proposed
merger, and on April 27, 1999:

</TABLE>
 
    The estimated equivalent per share price of a share of DSPT common stock
based on MTS share price of $10.313 equals an assumed exchange ratio of 0.8355
multiplied by the price of a share of MTS common stock. If the merger had
occurred on April 27, 1999, you would have received a fraction of a share of MTS
common stock worth approximately $9.39 per share for each share of DSPT common
stock you owned. The actual equivalent per share price of a share of DSPT common
stock that you will receive if the merger closes may be different from this
price because the actual exchange ratio will not be determined until closing and
because the per share price of MTS common stock on the Nasdaq National Market
fluctuates continuously.
 
    Following the merger, MTS common stock will continue to be quoted on the
Nasdaq National Market, and there will be no further market for the DSPT common
stock.

    MTS' dividend policy is to maintain a payout ratio which allows dividends to
increase with the long-term growth of earnings per share, while sustaining
dividends in down years. MTS' dividend payout ratio target is approximately 25%
of earnings per share. The current quarterly dividend of $0.06 per share equates
to 26% of MTS' fiscal 1996 through fiscal 1998 average net earnings per share.
 
    DSPT has never declared or paid a dividend. DSPT's policy is to retain
earnings for use in its business.

                           COMPARATIVE PER SHARE DATA
 
    Set forth below are the net income and book value per common share data for
MTS on a historical basis and on a combined pro forma basis, and certain
equivalent pro forma per share data for DSPT. The MTS combined pro forma data
was derived by combining historical consolidated financial information of MTS
and DSPT using the pooling of interests method of accounting for business
combinations. The equivalent combined pro forma per share data for DSPT was
calculated by multiplying the MTS combined pro forma per common share data by an
assumed exchange ratio of .8037. The equivalent historical per common share data
for DSPT was calculated by dividing the DSPT historical per common share data by
 .8037.
 
    The information in the table below should be read in conjunction with the
respective audited and unaudited consolidated financial statements and related
notes of MTS and DSPT either incorporated by reference in this proxy
statement/prospectus or included elsewhere in this proxy statement/ prospectus.

                            THE DSPT SPECIAL MEETING
 
DATE, TIME AND PLACE OF MEETING
 
    The DSP Technology Inc. special meeting will be held at DSPT's offices
located at 48500 Kato Road, Fremont, California, on Friday, May 28, 1999 at 2:00
p.m. local time.
 
PURPOSE OF THE DSPT SPECIAL MEETING
 
    The purpose of the DSPT special meeting is to approve and adopt the merger
agreement and the merger. DSPT stockholders may also consider and vote upon such
other matters as may properly come before the DSPT special meeting or any
adjournments or postponements of the meeting.
 
RECORD DATE AND OUTSTANDING SHARES
 
    The DSPT board of directors has fixed April 15, 1999 as the record date for
the DSPT special meeting. Only stockholders of record of DSPT common stock on
the record date are entitled to notice of, and to vote at, the DSPT special
meeting. As of the record date, there were 90 stockholders of record holding an
aggregate of 2,351,076 shares of DSPT common stock. Except for the stockholders
identified under "Information with Respect to DSPT--Principal Stockholders" on
page 61, to the knowledge of DSPT, no other person beneficially owned more than
5% of the outstanding DSPT common stock as of the record date.
 
    This proxy statement/prospectus was mailed to all DSPT stockholders of
record as of the record date and constitutes notice of the DSPT special meeting
in conformity with the requirements of the Delaware General Corporation Law.
 
VOTING OF PROXIES
 
    All properly executed proxies that are not revoked will be voted at the DSPT
special meeting in accordance with the instructions contained in the proxy. If a
stockholder signs and returns a proxy without indicating any voting
instructions, the shares of DSPT common stock that the proxy represents will be
voted "FOR" the proposal to adopt and approve the merger agreement and approve
the merger under the recommendation of the DSPT board of directors or "FOR"
adjournment or postponement of the DSPT special meeting if an adjournment or
postponement, in the discretion of the proxy holders, is determined to be
necessary or desirable. A stockholder who has executed and returned a proxy may
revoke it at any time before it is voted at the DSPT special meeting by:
 
    - executing and returning a proxy bearing a later date;
 
    - filing written notice of such revocation with the secretary of DSPT
      stating that the proxy is being revoked; or
 
    - attending the DSPT special meeting and voting in person.
 
    All written notices of revocation and other communications with respect to
revocation of DSPT proxies should be sent to: DSP Technology Inc., 48500 Kato
Road, Fremont, CA 94538, Attention: Secretary. Attendance at the DSPT special
meeting, in and of itself, will not constitute a revocation of a proxy.
 
VOTE REQUIRED
 
    Adoption and approval of the merger agreement and approval of the merger
require the affirmative vote of holders of a majority of the shares of DSPT
common stock outstanding as of the record date. Each stockholder of record of
DSPT common stock on the record date is entitled to cast
 
                                       19
<PAGE>
one vote per share, exercisable in person or by properly executed proxy, on each
matter properly submitted for the vote of the stockholders of DSPT at the DSPT
special meeting.
 
    At the record date for the special meeting, the directors and executive
officers of DSPT owned approximately 8.1% of the outstanding shares of DSPT
common stock entitled to vote at such meeting. All of them have agreed to vote
their shares for the adoption of the merger agreement and approval of the
merger.
 
QUORUM; ABSTENTIONS; BROKER NON-VOTES
 
    The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of DSPT common stock entitled to vote at the
DSPT special meeting is necessary to constitute a quorum. Abstentions will be
counted for purposes of determining a quorum, but will have the effect of a vote
against approval of the matters being voted upon. If a broker holding shares in
street name returns an executed proxy that indicates that the broker does not
have discretionary authority as to those shares to vote on one or more matters,
those shares will be considered represented at the DSPT special meeting for
purposes of determining a quorum, but will have the effect of a vote against
approval of the matters being voted upon.
 
SOLICITATION OF PROXIES; EXPENSES
 
    DSPT will bear the cost of the solicitation of proxies and all related
costs. In addition, DSPT may reimburse brokerage firms and other persons
representing beneficial owners of shares for their expenses in forwarding
solicitation materials to such beneficial owners. Certain directors, officers or
other employees of DSPT may supplement original solicitation of proxies by mail
with telephone, facsimile or personal solicitation, without payment of
additional compensation. DSPT has engaged the services of Mackenzie Partners,
Inc. to distribute proxy solicitation materials to brokers, banks and other
nominees and to assist in the solicitation of proxies from DSPT stockholders for
a fee of approximately $5,000 plus reasonable out-of-pocket expenses.
 
EXCHANGE OF STOCK CERTIFICATES
 
    If you are a DSPT stockholder, you should not send in your stock
certificates now. After the merger is completed, MTS will send DSPT stockholders
and optionholders written instructions for receiving shares of MTS common stock
in exchange for their stock certificates and options. MTS stockholders will keep
their current certificates, and will continue to hold the same number of shares
of MTS common stock after the merger.
 
OTHER MATTERS
 
    As of the date of this proxy statement/prospectus, the DSPT board of
directors does not know of any business to be presented at the special meeting
other than as set forth in the notice accompanying this proxy
statement/prospectus. If any other matters should properly come before the
special meeting, it is intended that the shares represented by proxies will be
voted with respect to such matters in accordance with the judgment of the
persons voting such proxies.

                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS
 
BACKGROUND OF THE MERGER
 
    The terms and conditions of the merger agreement and the merger are the
result of arms' length negotiations between representatives of MTS and
representatives of DSPT. A summary of those negotiations follows:
 
    During late 1997 and throughout 1998, the DSPT board considered various
strategic relationships and other alternatives to increase stockholder value. On
August 17, 1998, the DSPT board of directors approved the engagement of Douglas
Hajjar, an experienced financial advisor, to assist the board in evaluating
DSPT's strategic alternatives.
 
    In August of 1998, MTS identified DSPT as a possible acquisition candidate
in connection with MTS' product line extension strategy. MTS concluded that
DSPT's transportation group products would constitute a strategic extension of
MTS' existing powertrain product line.
 
    On October 22, 1998, Mr. Troutman, President and Chief Executive Officer of
DSPT, received a letter dated October 15, 1998 from Hal Galvin, MTS' Vice
President, Corporate Business Development, proposing a strategic business
combination between the two companies. On October 26, 1998, after conferring
with Gray Cary Ware & Freidenrich LLP, DSPT's outside legal counsel, DSPT's
financial advisor, Mr. Hajjar, and the individual DSPT directors, Mr. Troutman
advised Mr. Galvin that DSPT could not respond to MTS without a specific
proposal, that DSPT was executing on its strategic plan, and that its current
stock price did not reflect DSPT's value. Mr. Galvin expressed MTS' interest in
engaging in a dialogue with DSPT about a possible strategic business
combination, but no specific proposal was advanced. Mr. Galvin invited Mr.
Troutman to visit MTS headquarters to permit representatives of the two
companies to learn more about each other's business and possible synergies from
a strategic business combination.
 
    In a regularly scheduled meeting of the DSPT board of directors on November
16, 1998 at Webers Inn, Ann Arbor, Michigan, at which all DSPT directors were
present, Mr. Troutman reviewed with the DSPT board his conversation with Mr.
Galvin and possible risks and benefits of a strategic business combination with
MTS. The board of directors authorized Mr. Troutman to explore a possible
relationship with MTS and to consider other possible strategic alternatives.
 
    Mr. Troutman visited MTS headquarters on November 19, 1998, and met with Dr.
Sidney W. Emery, Jr., Chairman and Chief Executive Officer of MTS, Keith Zell,
Executive Vice President of MTS, Steven Cohoon, MTS Vice President of Vehicle
Dynamics Division, and Hal Galvin. The representatives of the two companies
discussed their respective businesses and possible synergies which might be
achieved in a strategic business combination.
 
    At a regularly scheduled meeting of DSPT's board of directors at Clubsport,
Fremont, California, on December 4, 1998 at which all directors were present,
Mr. Troutman updated the board on various strategic alternatives, including his
meeting at MTS. The directors discussed publicly available information
concerning MTS and other possible strategic alternatives.
 
    On December 7, 1998, in a telephone conversation between Mr. Galvin and Mr.
Troutman, Mr. Galvin expressed MTS' continuing interest in a possible business
combination between the two companies, but no specific terms were discussed. On
December 21, 1998, Mr. Galvin advised Mr. Troutman in a telephone conversation
that MTS was interested in a business combination and the two had preliminary
discussions regarding possible structures and valuation. On December 22, 1998,
Mr. Troutman advised Mr. Galvin in a telephone conversation that the DSPT board
would consider, in early January, the possibility of a business combination with
MTS, but that the preliminary sense of individual directors was that while the
strategic fit between the companies appeared promising, MTS' proposed valuation
range was too low.
 
                                       21
<PAGE>
    In a January 5, 1999 telephone meeting of the DSPT board of directors at
which all DSPT directors were present, Mr. Troutman updated the board regarding
the late December 1998 contact by MTS. The directors reviewed DSPT's strategic
direction, business and synergies, as well as its prospects and risks in
achieving the operating plan. The directors also considered other strategic
alternatives, and DSPT's obligations to notify FEV Motorentechnik GmbH, DSPT's
strategic alliance partner, of certain offers constituting a transfer of
control. The DSPT board instructed Mr. Troutman and Mr. Hajjar to continue
discussions with MTS to determine if an acceptable offer would likely be
forthcoming.
 
    From January 6, 1999 through January 8, 1999, Messrs. Troutman and Galvin
exchanged information concerning capitalization and possible structures for a
strategic business combination. From January 8, 1999 through January 18, 1999,
the parties reviewed publicly available information concerning the respective
companies.
 
    On Monday, January 18, 1999, at a regularly scheduled meeting of the DSPT
board of directors at Clubsport, Fremont, California, at which all directors and
outside legal counsel were present, Mr. Troutman updated the directors on
discussions with MTS. At that same meeting, the board of directors approved a
transition plan for DSPT under which DSPT's principal executive offices and
transportation group would be consolidated in Ann Arbor, Michigan. DSPT
announced the planned consolidation and an estimate of an associated accounting
charge in a press release on January 21, 1999. On the same date, following the
announcement of the consolidation, Mr. Troutman advised Mr. Galvin of the
announcement. Mr. Galvin reviewed with Mr. Troutman MTS' current proposal on
valuation and structure.
 
    At a telephonic meeting of the DSPT board of directors on January 21, 1999
at which all DSPT directors and outside legal counsel were present, Mr. Troutman
reviewed his discussions with Mr. Galvin, including MTS' initial proposal on
valuation, with the board. The board of directors considered advice from DSPT's
financial advisor, Mr. Hajjar, and DSPT's outside counsel and discussed
strategies for further discussions with MTS. The board of directors also
instructed Mr. Troutman to advise DSPT's strategic alliance partner, FEV, that a
transaction by a third party to acquire DSPT might be proposed in the near term
and determine FEV's possible interest in a strategic business combination with
DSPT. The directors considered the tax effects of a cash transaction, which the
directors believed would be the most likely proposal by FEV.
 
    On January 22, 1999, Mr. Troutman advised Professor Franz Pischinger,
President and Chief Executive Officer of FEV, that DSPT had been approached by a
possible acquiror and that an acquisition proposal might be forthcoming in the
near term. Professor Pischinger advised Mr. Troutman that he would consider
FEV's possible interest in acquiring DSPT.
 
    In a telephone conversation on January 25, 1999, Mr. Troutman, Mr. Hajjar
and Mr. Galvin discussed possible valuations and structure. However, no
agreement was reached.
 
    At a telephonic meeting of the DSPT board of directors on January 25, 1999
at which all DSPT directors were present, Mr. Troutman and Mr. Hajjar summarized
the parties' discussions regarding structure and valuation, the treatment of
options, the possible accounting treatment for a proposed transaction, and
business conditions expected for DSPT in 1999. The board of directors authorized
Mr. Troutman and Mr. Hajjar to pursue negotiations with MTS to determine if a
transaction on acceptable terms to DSPT was possible. Later on January 25, 1999,
Messrs. Troutman, Hajjar and Galvin discussed possible synergies in a business
combination between the two companies, as well as the parties' respective views
on valuation and structure, but no agreement on valuation or structure was
reached.
 
    On January 26, 1999, the MTS board of directors considered a presentation by
MTS management regarding a possible acquisition of DSPT. The MTS board
authorized management to continue discussions regarding a possible acquisition
of DSPT.
 
                                       22

    On January 27, 1999, Mr. Galvin advised Mr. Troutman that the proposed
business combination had been discussed at the MTS board of directors meeting,
but that no valuation or terms had been approved.
 
    At a telephonic meeting of the DSPT board of directors on January 28, 1999
at which all DSPT directors were present, Mr. Troutman and Mr. Hajjar reviewed
the parties' discussions regarding valuation and the DSPT board of directors
discussed strategies for further discussions regarding valuation and deal
structure. The board then authorized Messrs. Troutman and Hajjar to have further
discussions with MTS representatives.
 
    Later on January 28, 1999, Messrs. Troutman, Hajjar, Galvin, and Robert
Clobes, Controller of MTS, had a telephone conversation regarding valuation and
structure. The parties agreed that a transaction would be proposed as a tax-free
stock-for-stock exchange, accounted for as a pooling of interests. Messrs.
Galvin and Clobes advised that no DSPT stock options would be assumed, and that
MTS would provide a fixed number of shares of MTS common stock representing a
valuation proposed by MTS. The parties discussed the possibility of a "collar,"
pursuant to which if the MTS stock price went above or below agreed upon prices
the parties would have a right to renegotiate. Messrs. Troutman and Hajjar
advised that DSPT intended to provide for the outstanding options by a cashless
exercise if an agreement on valuation and structure could be reached. The
parties discussed a possible due diligence process. Mr. Galvin advised that MTS
would not proceed without a letter of intent that contained a binding "no shop"
provision, under which DSPT would be restricted from seeking alternative
transactions. He also indicated that the valuation proposed by MTS was MTS' best
and final offer.
 
    At a telephonic meeting of the DSPT board of directors on January 29, 1999
at which all DSPT directors and outside legal counsel were present, Messrs.
Troutman and Hajjar reviewed MTS' oral proposal, including the proposed
valuation and the fixed share amount, subject to a collar to be negotiated, and
reviewed the parties' negotiation on valuation and structure. Messrs. Troutman
and Hajjar advised that MTS' proposal on valuation was represented as MTS' best
and final offer. Outside legal counsel reviewed with the directors their
fiduciary duties in considering an acquisition proposal, including their duties
in considering a "no shop" agreement. The board of directors discussed the
cashless exercise of options and its effect on merger consideration per common
share and net option share. The board of directors also considered the effect of
a "collar" on the value to DSPT stockholders and the risks of a collar. The
directors also reviewed with counsel DSPT's obligations under the strategic
alliance agreement with FEV and the notice required if DSPT were to receive a
"serious, credible offer" for a transfer of control transaction. Counsel advised
on the possible adverse effects of a transfer of control involving a
"competitor" of FEV as such term was used in the strategic alliance agreement.
The board of directors concluded that MTS was not a "competitor" of FEV under
that agreement. The board of directors then reviewed other strategic
alternatives. After this review, the DSPT board of directors instructed Mr.
Troutman to advise FEV that DSPT expected an offer which would result in a
transfer of control in the next few days in the form of a nonbinding letter of
intent, while not revealing the identity of the possible offeror.
 
    On February 1, 1999, Mr. Troutman advised Professor Pischinger and Dr.
Schaffrath, Executive Vice President of FEV, that DSPT expected a nonbinding
letter of intent with an offer in the next few days, and that the offeror was
not a "competitor" of FEV as such term was defined in the strategic alliance
agreement between DSPT and FEV. Mr. Troutman did not identify the possible
acquiror. Professor Pischinger indicated that FEV was not in a position to make
an offer to purchase DSPT.
 
    At a telephonic meeting of the DSPT board of directors on February 1, 1999
at which all DSPT directors were present, outside legal counsel reviewed a
memorandum regarding the fiduciary duties of the board in considering an
acquisition proposal. Messrs. Troutman and Millares, DSPT's Chief Financial
Officer, reviewed the accounting treatment for the proposed acquisition and the
consequences
 
                                       23
<PAGE>
of treatment of options with DSPT's independent accountants. Mr. Troutman
reviewed his conversation with FEV representatives. The directors reviewed
financial information concerning MTS and the trading prices for MTS common
stock. The board of directors discussed with counsel the advisability of a
fairness opinion in connection with any binding agreement on valuation and the
board of directors requested that Mr. Hajjar identify investment bankers who
might be willing to serve in such an engagement. The board of directors
discussed the possible effect of a "collar" on the valuation to stockholders.
The board of directors discussed business and legal due diligence with counsel,
management and the board's financial advisor. The board also discussed the
relative liquidity and volatility of MTS common stock and DSPT common stock,
relative trading volumes and analyst coverage and DSPT's growth prospects. The
board of directors authorized management to continue discussions with MTS.
 
    Later on February 1, 1999, Mr. Galvin advised Messrs. Troutman and Hajjar in
a telephone conversation that a nonbinding letter of intent was being prepared.
The representatives discussed a possible due diligence process.
 
    On February 2, 1999, MTS released its quarterly results for the quarter
ended December 31, 1998. On February 2 and February 3, 1999, representatives of
DSPT and MTS discussed MTS' proposal for a collar around an agreed upon
valuation, which would operate to adjust the number of MTS shares to be issued
in the merger depending on the MTS stock price on closing. No agreement was
reached on the proposal. Later on February 3, 1999, MTS faxed a nonbinding
letter of intent to Mr. Troutman.
 
    At a telephonic meeting of the DSPT board of directors on February 3, 1999
at which all DSPT directors and outside legal counsel were present, management,
outside legal counsel and Mr. Hajjar provided a preliminary review of the terms
of the nonbinding letter of intent to the directors. Messrs. Troutman and Hajjar
reviewed the representative's recent negotiations on valuation and the "collar,"
and the financial terms proposed in the letter, as well as the proposed
treatment of stock options. The board of directors discussed the effect of the
proposed collar, as well as the termination, "no shop" and breakup fee
provisions. The board of directors directed management and outside legal counsel
to negotiate the terms of the letter of intent.
 
    On February 3, 1999, DSPT and MTS entered into a mutual nondisclosure and
standstill agreement under which each company agreed not to disclose
confidential information that it had learned about the other and not to take any
action to acquire capital stock of the other party for a period of one year
without the prior consent of the other party.
 
    On February 4, 1999, at a telephonic meeting of the DSPT board of directors
at which all directors and outside legal counsel were present, outside legal
counsel and Mr. Hajjar reviewed with the board of directors in detail the terms
of the proposed letter of intent. The board of directors discussed the possible
engagement of Hambrecht & Quist LLC to provide a fairness opinion on the
transaction. On February 6, 1999, DSPT provided comments to MTS regarding the
proposed letter of intent.
 
    Also on February 6, 1999, DSPT notified FEV of the receipt of the letter of
intent, identifying MTS as the offeror, providing the proposed financial terms
of the transaction, noting that DSPT intended to negotiate the terms and
advising that MTS was not a "competitor" of FEV under the strategic alliance
agreement. DSPT also notified MTS on that same date of certain provisions of the
strategic alliance agreement relating to transfers of control. Each notice was
made as required by the strategic alliance agreement. On that same date in
response to the notice, Professor Pischinger called to discuss the transaction
with Mr. Troutman and advised Mr. Troutman that FEV considered MTS a
"competitor" under the strategic alliance agreement.
 
    On February 8, 1999, representatives of MTS and DSPT, together with their
respective outside counsel, negotiated the terms of the proposed nonbinding
letter of intent.
 
                                       24
<PAGE>
    On February 8, 1999, at a telephonic meeting of the DSPT board of directors
at which all DSPT directors and outside legal counsel were present, outside
legal counsel and Mr. Hajjar reviewed with the board of directors the results of
the representatives' negotiations on the nonbinding letter of intent. The DSPT
board of directors authorized the officers to enter into the nonbinding letter
of intent on substantially the terms presented. On February 9, 1999, MTS and
DSPT entered into a nonbinding letter of intent.
 
    Also on February 9, 1999, Professor Pischinger and Dr. Schaffrath advised
Mr. Troutman that Professor Pischinger had discussed the strategic alliance
agreement with Dr. Emery of MTS and believed that MTS was a "competitor" under
the strategic alliance agreement. Following this conversation, representatives
of DSPT and FEV continued to discuss the issue. On February 12, 1999, Professor
Pischinger telecopied a formal written request that MTS be added to the
"competitor list" under the strategic alliance agreement. After consultation
with outside legal counsel, on February 12, 1999, Mr. Troutman responded in
writing and by telephone to FEV indicating that DSPT did not agree that MTS was
a competitor of FEV.
 
    On February 10, 1999, MTS and DSPT made due diligence requests of each
other. From February 11, 1999 through the date of signing the definitive
acquisition agreement, representatives of MTS and DSPT conducted due diligence
investigations of each other's businesses.
 
    On February 11, 1999, DSPT engaged Hambrecht & Quist LLC to advise on the
fairness of the merger to DSPT stockholders from a financial point of view.
 
    On February 14, 1999, FEV again asserted in writing that MTS was a
"competitor" of FEV under the agreement, but proposed that a business resolution
was possible. Representatives of DSPT and FEV discussed possible business
resolutions to FEV's concerns through February 19, 1999.
 
    On February 17, 1999, outside legal counsel for MTS delivered to outside
legal counsel for DSPT an initial draft of the definitive merger agreement. From
February 17, 1999 through March 23, 1999, MTS and DSPT and their respective
outside legal counsel negotiated the terms of the merger agreement and related
agreements.
 
    On February 23, 1999, Mr. Galvin and Mr. Troutman met with Professor
Pischinger and Dr. Schaffrath in Aachen, Germany regarding a possible business
relationship among the parties. Professor Pischinger and a representative of
each of MTS and DSPT had additional meetings regarding a proposed business
relationship on February 28, 1999, March 3 and March 5, 1999 in Ann Arbor and
Detroit, Michigan and Eden Prairie, Minnesota. On March 9, 1999, counsel for MTS
delivered to counsel for FEV a draft agreement regarding the proposed business
relationship between the parties if the merger were consummated and MTS and FEV
and their respective legal counsel negotiated the terms of this agreement from
March 12, 1999 through March 20, 1999.
 
    On February 22, 1999, the MTS board of directors met to discuss the terms of
the merger agreement and the merger. On February 24, 1999, the MTS board of
directors by written action ratified the letter of intent with DSPT and
authorized MTS management to proceed with the negotiation and execution of the
definitive merger agreement and consummation of the merger.
 
    On March 1, 1999, at a regularly scheduled meeting of the DSPT board of
directors at the Webers Inn, Ann Arbor, Michigan, all directors were present in
person. Also in attendance were DSPT's outside legal counsel and members of
management. The board of directors ratified the engagement of Hambrecht & Quist
LLC to advise on the fairness of the merger consideration to the DSPT
stockholders. Representatives of Hambrecht & Quist LLC then joined the meeting
by telephone. Mr. Troutman reviewed the strategic rationale for the merger, and
possible risks and benefits of the merger. Outside legal counsel reviewed the
negotiations to date on the merger agreement and the proposed merger agreement,
including the termination provisions and the timing of any payment of breakup
fees, the no-shop provision, the conditions to the merger, the treatment of
options and the
 
                                       25
<PAGE>
representations and covenants. The board of directors considered legal and
business due diligence relating to MTS, and management reviewed possible
synergies in connection with the proposed business combination. Mr. Troutman
summarized the status of discussions among FEV, DSPT and MTS.
 
    On March 1, 1999, the directors of DSPT had a dinner meeting with Messrs.
Emery and Zell, to discuss the businesses of the respective companies, the
strategic rationale for the merger and the possible synergies and risks of the
transaction.
 
    On March 15, 1999, Dr. Emery advised Mr. Troutman by telephone that MTS was
not willing to proceed with the proposed transaction unless the terms of the
merger agreement were revised to remove the collar and eliminate any adjustment
in the number of shares of MTS common stock to be issued to DSPT stockholders as
a result of the price of MTS common stock at the closing. Dr. Emery explained
that the MTS board of directors was concerned about possible dilution to MTS
stockholders.
 
    On March 16, 1999, a special meeting of the DSPT board of directors was held
telephonically and all DSPT directors were present. Also in attendance were
DSPT's financial advisor, Doug Hajjar, representatives of Hambrecht & Quist LLC
and Gray Cary Ware & Freidenrich LLP. The directors discussed with their
financial and legal advisors the effect of the removal of the collar on the
merger consideration to be received by the DSPT stockholders and holders of net
option shares, and possible implications of the request regarding MTS' future
operating results. After discussion, the board of directors requested that Mr.
Troutman and Mr. Hajjar engage in further discussions with MTS concerning this
request and the directors' concerns.
 
    Later on March 16, 1999, Messrs. Troutman and Hajjar discussed with Dr.
Emery DSPT's concerns. Dr. Emery advised that MTS would not proceed with the
merger if more than 2,077,000 shares of MTS common stock would be issued in the
transaction.
 
    On March 17, 1999, a special meeting of the DSPT board of directors was held
telephonically, and all directors were present. Also present were Mr. Hajjar,
and representatives of Hambrecht & Quist LLC and Gray Cary Ware & Freidenrich
LLP. Mr. Troutman reviewed DSPT's operating plan and the risks of achieving the
plan as well as business and growth prospects. Messrs. Troutman and Hajjar then
summarized their discussions with Dr. Emery and advised that MTS was unwilling
to issue more than 2,077,000 shares of MTS common stock, and therefore would not
proceed if the number of shares was adjusted as a result of a lower stock price.
The DSPT board of directors discussed with their financial and legal advisors
the effect of the removal of the collar on the merger consideration for DSPT
stockholders, the risks and benefits of the proposed merger, and other
alternatives available to DSPT. After discussion, the DSPT board of directors
unanimously authorized management and outside legal counsel to proceed with the
finalization of the merger agreement and related documents.
 
    On March 19, 1999, the MTS board of directors ratified its prior approval of
the merger and the merger agreement.
 
    On March 20, 1999, MTS and FEV entered into an agreement establishing a
reciprocal distributorship and licensing arrangement effective on the merger,
subject to DSPT's execution of the agreement.
 
    On March 23, 1999, a special meeting of the DSPT board of directors was held
at the Embassy Suites, Burlingame, California, at which all directors were
present. Also present were representatives of Hambrecht & Quist LLC and Gray
Cary Ware & Freidenrich LLP. Mr. Troutman reviewed the strategic rationale for
the merger. Outside legal counsel reviewed the negotiations relating to the
merger agreement and the final terms of the agreement. Representatives of
Hambrecht & Quist LLC then reviewed their financial analyses with respect to the
final terms of the proposed merger agreement and delivered an oral opinion
(subsequently confirmed in writing) that the merger consideration was fair to
the DSPT stockholders from a financial point of view. There followed a general
discussion of the risks and benefits of the merger. The DSPT board of directors
concluded, by the unanimous vote of the
 
                                       26
<PAGE>
directors, that the merger was fair to and in the best interests of DSPT and its
stockholders and approved the merger agreement and related agreements, and
authorized DSPT management to proceed with the merger.
 
    On March 23, 1999, after the closing of trading on the Nasdaq National
Market and following the approval of the merger agreement by the DSPT board of
directors, representatives of both companies executed and delivered the merger
agreement and related documents. Also on March 23, 1999, a representative of
DSPT executed the agreement among FEV, MTS and DSPT, which among other matters,
resolved that MTS was not a competitor of FEV for purposes of the merger.
 
    On March 23, 1999, after the closing of trading on the Nasdaq National
Market, MTS issued a press release announcing the execution of the merger
agreement and the agreement among FEV, MTS and DSPT, and DSPT issued a press
release announcing the execution of the merger agreement.
 
REASONS FOR MERGER
 
    JOINT REASONS FOR THE MERGER
 
    MTS and DSPT have identified several potential benefits of the merger that
they believe will contribute to the success of the combined company. These
potential benefits include:
 
    - the ability to integrate MTS' powertrain unit operations with DSPT's
      transportation group, providing the opportunity to leverage the respective
      operations, engineering and sales and support organizations;
 
    - the potential to leverage research and development capabilities of each
      company, including mechanical engineering, electronic and software
      development skills and to share technology;
 
    - the ability to achieve economies of scale in corporate infrastructure; and
 
    - the potential to exploit further the strategic alliance relationship among
      MTS, FEV and DSPT.
 
    MTS' REASONS FOR THE MERGER
 
    MTS' board of directors has determined the merger is in the best interests
of MTS and its shareholders. In reaching its determination, the MTS board of
directors considered a number of factors, including the matters discussed above
under "Joint Reasons for the Merger" and the following:
 
    - the technical, engineering, management and sales expertise of DSPT;
 
    - the judgment, advice and analysis of MTS' management with respect to the
      potential strategic, financial and operational benefits of the merger,
      including MTS management's favorable recommendation of the merger, based
      in part on the business, technical, financial accounting and legal due
      diligence investigations performed with respect to DSPT;
 
    - the results of operations and financial condition of MTS and DSPT, and the
      anticipated accretive effect, in MTS' operating results for fiscal year
      2000, taken as a whole, of the merger on MTS' common stock;
 
    - the complementary fit between MTS' and DSPT's products, cultures, market
      segments and distribution channels, which are expected to facilitate
      integration of the two companies;
 
    - the terms of the merger agreement and related agreements, including price
      and structure, which were considered by both the board and management of
      MTS to provide a fair and equitable basis for the merger;
 
    - the ability of MTS to account for the merger as a pooling of interests for
      financial accounting purposes;
 
                                       27
<PAGE>
    - the fact that the merger will further MTS' commitment to customers to
      provide a broader and more integrated analysis, simulation and testing
      process that will enable customers to lower development costs and move
      products to market faster;
 
    - DSPT's unique expertise, technologies and customer recognition in the
      market for test, analysis and validation of engine designs; and
 
    - the belief that the combined firms would be a stronger force in the global
      powertrain development and testing market because they complement each
      other in technology, customer base and geographic presence.
 
    The MTS board of directors also considered certain potentially negative
factors that may result from the merger, including:
 
    - the potential dilutive effect on MTS' common stock price if revenue and
      earnings expectations of the combined company are not achieved;
 
    - the dilutive effect on MTS' earnings per share in MTS' fiscal 1999 which
      will principally result from one time charges relating primarily to costs
      of the transaction;
 
    - the potential loss of key DSPT employees critical to the ongoing success
      of the DSPT products and product development and to the successful
      integration of MTS' and DSPT's powertrain product lines;
 
    - the general difficulties of integrating product lines, technologies,
      research and development efforts, and companies; and
 
    - the other risks and uncertainties discussed above under "Risk Factors" on
      page 9.
 
    In analyzing the proposed merger, the MTS board did not view any single
factor as determinative and did not quantify or assign weight to any of the
factors. Rather, the MTS board made its determination based upon the total mix
of information available to it.
 
    DSPT'S REASONS FOR THE MERGER
 
    The DSPT board of directors believes that its ability to grow DSPT's
business as a relatively small independent company, competing with larger
companies with substantially greater resources and broader, integrated product
offerings, is challenged. DSPT's management considered the alternatives of
either acquiring smaller companies that could extend its product and service
offerings or enhance the distribution of its products and services, or merging
with a larger company. In this environment, the DSPT board of directors
identified several potential benefits for the DSPT stockholders and customers
that it believes would result from the merger. These potential benefits include
the benefits discussed above under "Joint Reasons for the Merger" and the
following:
 
    - the potential to obtain contracts for larger system integration projects
      due to the lower perceived risk to customers as a result of the larger
      relative size of the combined company compared to DSPT;
 
    - the potential for increased sales to MTS' powertrain unit customers,
      primarily as a result of combining product lines of the powertrain unit
      and DSPT to offer diesel customers broader test capabilities and
      complementary product lines;
 
    - the potential for increased sales of DSPT products to MTS powertrain
      component test product customers;
 
    - the opportunity for increased DSPT international sales as a result of
      leveraging MTS' international business;
 
                                       28
<PAGE>
    - the potential for increased sales in the powertrain testing market as a
      result of integrating MTS' noise and vibration capability into DSPT
      products; and
 
    - the greater liquidity and diversification of risk offered to DSPT
      stockholders by an investment in MTS instead of DSPT.
 
    In the course of its deliberations, the DSPT board of directors reviewed
with DSPT's management a number of additional factors relevant to the merger,
including, among others:
 
    - the information concerning MTS' and DSPT's respective businesses,
      prospects, financial performance and condition, operations, technology,
      product and service lines, management and competitive position, current
      market conditions and historical market prices, volatility and trading
      information with respect to MTS common stock and DSPT common stock;
 
    - the consideration that DSPT stockholders will receive in the merger and
      the fact that at the time the parties signed the merger agreement, the
      market value of the MTS common stock to be issued in exchange for the DSPT
      common stock represented a significant premium over the recent price range
      of the DSPT common stock;
 
    - the fact that although MTS was not assuming DSPT stock options, DSPT
      stockholders and holders of net option shares would receive the pro rata
      benefit of the aggregate exercise price for stock options outstanding on
      the closing of the merger;
 
    - the greater liquidity of the MTS common stock as compared with DSPT common
      stock;
 
    - the larger size, relative stability and greater investor visibility of MTS
      as compared with DSPT;
 
    - the current industry and economic conditions;
 
    - the implications for continued independent operation of DSPT in light of
      market and competitive conditions, including the potential for increased
      competition from companies having significantly greater resources than
      DSPT;
 
    - the complementary products and services, channels, partners, technology
      and critical skills of MTS and DSPT;
 
    - the alternatives available to DSPT compared to the consideration proposed
      to be paid to stockholders pursuant to the merger agreement;
 
    - the belief that the terms of the merger agreement are reasonable,
      including the provisions allowing DSPT to respond to certain unsolicited
      inquiries regarding an acquisition of DSPT, and the provisions that permit
      DSPT to terminate the merger agreement upon payment to MTS of a break-up
      fee under certain circumstances;
 
    - a comparison of selected recent acquisition and merger transactions in the
      industry;
 
    - the view of the DSPT board of directors, based in part on the
      presentations of management and DSPT's financial advisors, regarding the
      likelihood of a superior offer arising;
 
    - the expected tax and accounting treatment of the merger;
 
    - the opinion of Hambrecht & Quist LLC rendered at the March 23, 1999
      meeting of the DSPT board of directors that, based upon and subject to the
      various assumptions and conditions set forth in the opinion, the merger
      consideration was fair to the holders of DSPT common stock from a
      financial point of view;
 
    - the impact of the merger on the customers and employees of DSPT; and
 
    - the reports from management, financial advisors and legal advisors as to
      the results of their due diligence investigation of MTS.
 
                                       29
<PAGE>
    The DSPT board of directors also considered a number of potentially negative
factors in its deliberations concerning the merger, including, but not limited
to:
 
    - the risk that the benefits sought to be achieved in the merger will not be
      achieved;
 
    - the fact that the number of shares of MTS common stock is fixed at
      2,077,000 and that there is no guarantee as to the market value of a
      fraction of a share of MTS common stock to be received for each share of
      DSPT common stock and each net option share or that such market value will
      represent at closing a premium over the price range of DSPT common stock
      prior to the announcement of the merger agreement;
 
    - the fact that the fraction of a share of MTS common stock to be received
      by a holder of DSPT common stock or net option shares will fluctuate based
      on the number of options which remain unexercised at the closing of the
      merger and the exercise prices of such options, and that in general the
      more options which are exercised prior to the closing, the smaller the
      fraction of a share of MTS common stock each holder of DSPT common stock
      and net option shares will receive;
 
    - the fact that the higher the price of MTS common stock on the closing, the
      higher the percentage of total merger consideration that will be paid to
      holders of net option shares compared to stockholders;
 
    - the fact that the future growth of MTS revenues, earnings or stock price
      may not equal or exceed the growth experienced by a small independent
      technology company;
 
    - the loss of control over the future operations of DSPT following the
      merger;
 
    - the effect of the public announcement of the merger on DSPT's sales,
      customer relations and operating results and DSPT's ability to attract and
      retain key management, marketing and technical personnel;
 
    - the risk of market confusion and potential delay or reduction in orders
      for products and services; and
 
    - the other risks described above in "Risk Factors" on page 9.
 
    The DSPT board of directors believed that certain of these risks were
unlikely to occur or unlikely to have a material impact on the stockholders or
the combined company, while others could be avoided or mitigated by DSPT or MTS,
and that overall the risks associated with the merger were outweighed by the
potential benefits of the merger.
 
    The foregoing discussion of information and factors considered by the DSPT
board of directors is not intended to be all inclusive, but is believed to
include all material factors considered by the DSPT board of directors. In view
of the wide variety of factors considered by the DSPT board of directors, the
DSPT board of directors did not find it practicable to quantify or otherwise
assign relative weight to the specific factors considered. However, after taking
into account all the factors set forth above, the DSPT board of directors
unanimously agreed that the merger agreement and the consummation of the merger
were fair to, and in the best interests of DSPT and its stockholders, and that
DSPT should proceed with the merger.
 
RECOMMENDATION OF THE DSPT BOARD
 
    The DSPT board of directors has unanimously adopted and approved the merger
agreement and approved the merger, and recommends a vote "FOR" the adoption and
approval of the merger agreement and approval of the merger by the DSPT
stockholders.

OPINION OF DSPT FINANCIAL ADVISOR
 
    DSPT engaged Hambrecht & Quist LLC to act as its financial advisor in
connection with the merger and, in such capacity, to render an opinion as to the
fairness from a financial point of view to the holders of the outstanding shares
of common stock of DSPT of the consideration to be received by such stockholders
in the merger. Hambrecht & Quist LLC was selected by the DSPT board of directors
based on its qualifications, expertise and reputation. Hambrecht & Quist LLC
rendered its oral opinion, subsequently confirmed in writing, on March 23, 1999
to the DSPT board of directors that, as of such date, the consideration to be
received by the holders of the DSPT common stock in the merger was fair to the
holders of the DSPT common stock from a financial point of view.
 
    A COPY OF HAMBRECHT & QUIST LLC'S OPINION DATED MARCH 23, 1999, WHICH SETS
FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED, THE SCOPE AND LIMITATIONS OF THE
REVIEW UNDERTAKEN AND THE PROCEDURES FOLLOWED BY HAMBRECHT & QUIST LLC IS
ATTACHED AS APPENDIX B TO THIS PROXY STATEMENT/PROSPECTUS. DSPT STOCKHOLDERS ARE
ADVISED TO READ THE OPINION IN ITS ENTIRETY.
 
    The assumptions made, matters considered and limits of review contained in
Hambrecht & Quist LLC's written opinion delivered March 23, 1999 were
substantially the same as those contained in the opinion attached to this proxy
statement/prospectus. No limitations were placed on Hambrecht & Quist LLC by the
DSPT board with respect to the investigation made or the procedures followed in
preparing and rendering its opinion.
 
    In its review of the merger, and in arriving at its opinion, Hambrecht &
Quist LLC, among other things:
 
    - reviewed the publicly available consolidated financial statements of MTS,
      for recent years and interim periods to date and certain other relevant
      financial and operating data of MTS, including its capital structure, made
      available to Hambrecht & Quist LLC from published sources;
 
    - discussed the business, financial condition and prospects of MTS with
      certain members of its senior management;
 
    - reviewed the consolidated financial statements of DSPT for recent years
      and interim periods to date and certain other relevant financial and
      operating data of DSPT made available to Hambrecht & Quist LLC from
      published sources and from the internal records of DSPT;
 
    - reviewed certain internal financial and operating information, including
      certain projections, relating to DSPT prepared by the management of DSPT;
 
    - discussed the business, financial condition and prospects of DSPT with
      certain members of its senior management;
 
    - reviewed the recent reported prices and trading activity for the common
      stocks of MTS and DSPT and compared such information and certain financial
      information for MTS and DSPT with similar information for certain other
      companies engaged in businesses Hambrecht & Quist LLC considered
      comparable;
 
    - reviewed the financial terms, to the extent publicly available, of certain
      comparable merger and acquisition transactions;
 
    - reviewed the merger agreement; and
 
    - performed such other analyses and examinations and considered such other
      information, financial studies, analyses and investigations and financial,
      economic and market data as Hambrecht & Quist LLC deemed relevant.
 
                                       31
<PAGE>
    Hambrecht & Quist LLC did not independently verify any of the information
concerning DSPT or MTS considered in connection with its review of the merger
and, for purposes of its opinion, Hambrecht & Quist LLC assumed and relied upon
the accuracy and completeness of all information considered. In connection with
its opinion, Hambrecht & Quist LLC did not prepare or obtain any independent
evaluation or appraisal of any of the assets or liabilities of DSPT or MTS, nor
did it conduct a physical inspection of the properties and facilities of DSPT or
MTS. With respect to the financial forecasts and projections used in its
analysis, Hambrecht & Quist LLC assumed that they reflected the best currently
available estimates and judgments of the expected future financial performance
of MTS and DSPT. For the purposes of its opinion, Hambrecht & Quist LLC also
assumed that neither DSPT nor MTS was a party to any pending transactions,
including external financings, recapitalizations or other material merger
discussions, other than the merger and those activities undertaken in the
ordinary course of conducting their respective businesses. For purposes of its
opinion, Hambrecht & Quist LLC assumed that the merger will qualify as a
tax-free reorganization under the Internal Revenue Code of 1986, as amended, for
the stockholders of DSPT and that the merger will be accounted for as a pooling
of interests. Hambrecht & Quist LLC's opinion was necessarily based upon market,
economic, financial and other conditions as they existed and could be evaluated
as of the date of the opinion and any subsequent change in the conditions would
require a reevaluation of the opinion.
 
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The summary
of the Hambrecht & Quist LLC analyses set forth below does not purport to be a
complete description of the presentation by Hambrecht & Quist LLC to the DSPT
board. In arriving at its opinion, Hambrecht & Quist LLC did not attribute any
particular weight to any analysis or factor it had considered, but rather made
qualitative judgments as to the significance and relevance of each analysis and
factor. Accordingly, Hambrecht & Quist LLC believes that its analyses and the
summary set forth below must be considered as a whole and that selecting
portions of its analyses, without considering all analyses, or of the following
summary, without considering all factors and analyses, could create an
incomplete view of the processes underlying the analyses set forth in the
Hambrecht & Quist LLC presentation to the DSPT board and its opinion. In
performing its analyses, Hambrecht & Quist LLC made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of DSPT and MTS. The
analyses performed by Hambrecht & Quist LLC, and summarized below, are not
necessarily indicative of actual values or actual future results, which may be
significantly more or less favorable than suggested by such analyses.
Additionally, analyses relating to the values of businesses do not purport to be
appraisals or to reflect the prices at which businesses actually may be
acquired.
 
    The following is a brief summary of financial analyses performed by
Hambrecht & Quist LLC in connection with providing its written opinion to the
DSPT board on March 23, 1999:
 
    PRO FORMA MERGER ANALYSIS
 
    Hambrecht & Quist LLC analyzed the pro forma impact of the merger on the
projected results of MTS for the fiscal years ending September 30, 1999 and
2000. Hambrecht & Quist LLC prepared financial projections for MTS based on Dain
Rauscher Wessels analyst estimates. Hambrecht & Quist LLC prepared financial
projections for DSPT based on DSPT management estimates. Hambrecht & Quist LLC
observed that based upon these forecasts, the merger resulted in greater
earnings for the pro forma combined company in the fiscal year ending September
30, 2000 than for MTS as a stand-alone company. The foregoing analysis did not
assume any adjustments to projected revenues or costs resulting from potential
operating synergies that may be realized from the merger. The actual results and
savings achieved by the combined company as a result of the merger may vary from
the projected results and such variations may be material.
 
                                       32
<PAGE>
    CONTRIBUTION ANALYSIS
 
    Hambrecht & Quist LLC analyzed the contribution of each of DSPT and MTS to
material financial statement categories of the pro forma combined company,
assuming no revenue or expense adjustments. The financial statement categories
compared included revenues, gross profit, operating income and pretax income.
This contribution analysis was then compared to the respective pro forma
ownership percentages of DSPT and MTS stockholders in the pro forma combined
company. Hambrecht & Quist LLC observed that, calculated on a fully-diluted
basis using the treasury stock method, DSPT shareholders are expected to own
approximately 10% of the combined company equity at the close of the merger and
MTS stockholders are expected to own approximately 90% of the combined company
equity at the close of the merger. For the fiscal year ending September 30,
1999, it was estimated that DSPT would contribute approximately 7% of revenues,
9% of gross profit, 7% of operating income, and 8% of pretax income of the
combined company. For the fiscal year ending September 30, 2000, it was
estimated that DSPT would contribute approximately 8% of revenues, 10% of gross
profit, 12% of operating income, and 13% of pretax income of the combined
company.
 
    PREMIUM ANALYSIS
 
    Based on the closing price of MTS common stock of $10.813 on March 22, 1999,
the implied value per share of DSPT common stock was approximately $8.93. This
represented a one day premium over the closing price for DSPT common stock on
March 22, 1999 of approximately 46%. Hambrecht & Quist LLC also analyzed the
implied premiums to average historical closing prices for the 1 week, 1 month, 3
months, 6 months and 1 year ending March 22, 1999 and determined that the
implied premiums were approximately 51%, 52%, 39%, 35% and 18%, respectively. In
addition, the implied premiums to the 52-week high and low closing prices of
DSPT common stock were approximately 66% and 16%, respectively.
 
    ANALYSIS OF PUBLICLY-TRADED COMPARABLE COMPANIES
 
    Hambrecht & Quist LLC compared selected historical and projected financial
information of DSPT to publicly-traded companies that Hambrecht & Quist LLC
deemed to be comparable to DSPT. This information included the ratios of market
value to historical net income, market value to projected calendar year 1999 net
income, and market value to book value. Hambrecht & Quist LLC also examined the
ratios of enterprise value, market value plus debt less cash, to historical
revenue, historical EBITDA, earnings before interest, taxes, depreciation and
amortization, and historical EBIT, earnings before interest and taxes. Companies
deemed comparable on the basis of their business activity and other factors such
as market capitalization and projected growth rates included Aero Systems
Engineering, Faro Technologies, Instron, Larson Davis, Modern Controls, MTS, and
Transmation. Hambrecht & Quist LLC determined average trading multiples for the
above companies of 0.9 times LTM, latest twelve months revenues, 6.4 times LTM
EBITDA, 9.1 times LTM EBIT, 13.0 times LTM net income, 9.5 times projected
calendar year 1999 net income, and 1.4 times book value.
 
    The foregoing multiples were applied to historical financial results of DSPT
for the twelve-month period ended January 31, 1999 and projected financial
results for DSPT. Based on the analysis of publicly-traded comparable companies,
Hambrecht & Quist LLC calculated a range of implied equity values ranging from
$7.41 per share to $11.56 per share. This compared with an implied value in the
proposed merger of approximately $8.93, based on the closing price of MTS common
stock on March 22, 1999.
 
    ANALYSIS OF SELECTED MERGER AND ACQUISITION TRANSACTIONS
 
    Hambrecht & Quist LLC compared the proposed merger with selected comparable
merger and acquisition transactions. This analysis included 11 transactions
involving companies that provide
 
                                       33
<PAGE>
instrumentation, measurement and control products. These transactions included
Liberty Technologies/ Crane, Satec Systems/Instron, Impact Systems/Voith Sulzer
Paper Technology, Waekon Industries/ Hickok, Computational Systems/Emerson
Electric, Chatillon & Lloyd/AMETEK, Petrotech/Roper Industries,
Measurex/Honeywell, Data Measurement/Meaurex, Uson/Roper Industries, and
Powertek/ MTS. In examining these transactions, Hambrecht & Quist LLC analyzed
certain income statement and balance sheet parameters of the acquired company
relative to the consideration offered. The multiples determined included
consideration offered as a multiple of LTM revenues, LTM EBITDA, LTM EBIT, LTM
net income, and book value. In addition, Hambrecht & Quist LLC determined the
one trading-day and twenty trading-day premiums paid in the above transactions
which involved the acquisitions of public companies. The consideration offered
in the above transactions was an average multiple of 1.2 times LTM revenue, 8.1
times LTM EBITDA, 9.0 times LTM EBIT, 13.9 times LTM net income, and 2.2 times
book value. The average one- and twenty-day premiums paid were 38.3% and 41.1%,
respectively.
 
    These multiples were applied to the historical financial results of DSPT for
the twelve-month period ended January 31, 1999. The foregoing premiums were
applied to the closing price of DSPT common stock for the one day and twenty
trading-days prior to March 23, 1999. Based on the analysis of selected merger
and acquisition transactions, Hambrecht & Quist LLC calculated a range of
implied equity values ranging from $8.47 per share to $13.71 per share. This
compared with an implied value in the proposed merger of approximately $8.93,
based on the closing price of MTS common stock on March 22, 1999.
 
    No company or transaction used in the above analyses is identical to DSPT or
the proposed merger. Accordingly, an analysis of the results of the foregoing is
not purely mathematical; rather it involves complex considerations and judgments
concerning differences in financial and operating characteristics of the
companies and other factors that could affect the values of the companies or
transactions to which they are compared.
 
    DISCOUNTED CASH FLOW ANALYSIS
 
    Hambrecht & Quist LLC analyzed the theoretical valuation of DSPT based on
the discounted free cash flow projected for DSPT using management's assumptions
regarding long-term growth and margins. To estimate the total present value of
DSPT's business, before giving effect to its capital structure, Hambrecht &
Quist LLC discounted to present value the projected stream of after-tax cash
flows produced by DSPT through the fiscal year ending January 31, 2004 and the
hypothetical value of selling the entire business at the end of this period (the
terminal value). The terminal value was based upon multiples of 5.0 to 7.0 times
projected EBITDA for the fiscal year ending January 31, 2004. In this analysis
Hambrecht & Quist LLC used discount rates ranging from 17.5% to 22.5%. Hambrecht
& Quist LLC calculated a range of present equity values ranging from $7.74 per
share to $12.95 per share. This compared with an implied value in the proposed
merger of approximately $8.93, based on the closing price of MTS common stock on
March 22, 1999.
 
    This description of Hambrecht & Quist LLC's opinion is qualified in its
entirety by reference to the full text of the opinion which is attached as
Appendix B to this proxy statement/prospectus.
 
    Hambrecht & Quist LLC, as part of its investment banking services, is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, corporate restructurings, strategic
transactions, negotiated underwritings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes.
 
    Pursuant to an engagement letter dated February 11, 1999, DSPT agreed to pay
Hambrecht & Quist LLC a fee of $150,000 in connection with the delivery of a
fairness opinion. DSPT also has agreed to reimburse Hambrecht & Quist LLC for
its reasonable out-of-pocket expenses and to indemnify Hambrecht & Quist LLC
against certain liabilities, including liabilities under federal
 
                                       34
<PAGE>
securities laws or relating to or arising out of Hambrecht & Quist LLC's
engagement as financial advisor.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    INDEMNIFICATION
 
    The merger agreement provides that after the effective time, all rights to
indemnification existing in favor of any person who is a current or prior
officer or director of DSPT for acts and omissions occuring prior to the
effective time shall survive the merger and shall be fulfilled and honored by
MTS and its wholly-owned subsidiary DSPT. MTS has agreed to maintain DSPT's
policy or policies of directors' and officers' liability insurance for not less
than six years following the effective time of the merger. Further, MTS has
agreed to provide capital to the extent DSPT lacks sufficient capital to pay the
premiums for this coverage.
 
    EMPLOYMENT ARRANGEMENTS
 
    DSPT has entered into retention agreements dated as of January 18, 1999 with
F. Gil Troutman, Jr., DSPT's President and Chief Executive Officer, and Larry
Moulton, DSPT's General Manager of the Transportation Group. If Mr. Troutman or
Mr. Moulton resigns for "good reason" or is terminated without "cause" within 12
months after the date of a merger or acquisition of DSPT, each officer is
entitled to all salary, accrued but unused vacation and his pro rata target
bonus for the year each through the date of his termination or resignation and
an additional 18 months (12 months for Mr. Moulton) of salary and bonus,
reimbursement of any expenses incurred in connection with DSPT's business,
reimbursement of his health insurance premiums for 18 months (12 months for Mr.
Moulton) and any benefits under DSPT's 401(k) plan or other benefit plans.
 
    In connection with the merger agreement, MTS has entered into separate
employment agreements with Mr. Troutman and Mr. Moulton which will become
effective upon the closing of the merger. Under the employment agreements, MTS
has agreed to employ Messrs. Troutman and Moulton after the merger becomes
effective and the retention agreements described above will have no effect.
 
    Mr. Troutman's employment agreement provides for a 36 month term of
employment after the merger becomes effective and yearly base compensation of
$200,000, subject to review annually by MTS. In addition, under the agreement,
Mr. Troutman is eligible for MTS' Management Variable Compensation Bonus Plan
and will be guaranteed a bonus of $9,250 for MTS' fiscal year 1999.
 
    Other benefits and compensation provided to Mr. Troutman under the agreement
are:
 
    - the use of an automobile;
 
    - participation in MTS' 401(k) and Profit Sharing Retirement plans;
 
    - the grant of an option to purchase 10,000 shares of MTS common stock
      priced at fair market value as of the effective time of the merger and an
      option to purchase at least 5,500 shares of common stock in subsequent
      years;
 
    - consideration for option grants when options are granted to other
      executives at MTS; and
 
    - the benefits under any other benefit or compensation plans that are
      adopted by MTS.
 
    If Mr. Troutman's employment is terminated by MTS during the first 36 months
of the agreement other than for death, disability or for "cause," as defined in
the employment agreement, he will be entitled to payment of his monthly base
salary of $16,666 and 1/24th of the bonus he has earned during the two most
recent fiscal years prior to the termination per month for the remainder of the
36-month term of the agreement and for a minimum of nine months. However, if Mr.
Troutman's employment is terminated during MTS' fiscal year ended September 30,
2000, the bonus payment will be 1/12th of the
 
                                       35
<PAGE>
bonus earned during the previous fiscal year. If his employment is terminated
during MTS' fiscal year ending September 30, 1999, the bonus payment will be
1/12th of the bonus that would have been earned that year based on actual
achievement of the established targets.
 
    In addition, for nine months after termination, MTS will continue Mr.
Troutman's health and life insurance benefits and pay the employer portion of
the premiums and his options will continue to be exercisable.
 
    Mr. Troutman has also agreed to non-compete, confidentiality and trade
secret provisions in the employment agreement.
 
    Mr. Moulton's employment agreement with MTS provides for substantially the
same terms as Mr. Troutman's, except that Mr. Moulton's yearly base salary shall
be $150,000. Mr. Moulton's compensation under the MTS Management Variable
Compensation Plan is also calculated at a lower rate than Mr. Troutman's.
Furthermore, Mr. Moulton will be granted an option to purchase 5,000 shares of
MTS common stock priced at fair market value as of the effective time of the
merger and an option to purchase at least 3,650 shares of MTS common stock in
subsequent years.
 
    Michael Ford and MTS have orally agreed that if Mr. Ford is terminated by
MTS other than for death, disability or cause, Mr. Ford will receive a severance
payment equal to at least six months of his base salary.
 
    STOCK OPTION ACCELERATION
 
    All options under the DSPT 1991 Directors' Stock Option Plan and 1991 Stock
Option Plan, the "Plans", and certain options issued outside the Plans contain
terms that provide that vesting of all such options will accelerate thirty days
prior to a transfer of control if the options are not assumed by the acquiror,
except that vesting with respect to options for 39,000 shares granted outside
the Plans do not accelerate upon a transfer of control. Under the terms of the
merger agreement, MTS has not assumed any outstanding options under the Plans or
otherwise. Accordingly, vesting with respect to all outstanding options other
than the unvested portion of options for 39,000 shares will accelerate thirty
days prior to the effective time of the merger.
 
AFFILIATE AGREEMENTS
 
    Each of the directors and executive officers of DSPT have entered into
agreements restricting sales, transfers, pledges, dispositions or other
transactions reducing their risk of investment relative to shares of DSPT common
stock and the shares of MTS common stock received by them in the merger, or
options to purchase common stock, during the period commencing 30 days prior to
the effective time of the merger and ending on the date on which financial
results covering at least 30 days of post-merger combined operations of MTS and
DSPT have been published by MTS. The agreements also restrict the sale, transfer
or other disposition of shares of MTS common stock received by them in the
merger except pursuant to an effective registration statement or in compliance
with Rule 145 or another exemption from the registration requirements of the
Securities Act. These agreements are intended to help ensure compliance with the
requirements of applicable federal securities and tax laws and to help ensure
that the merger will be treated as a pooling of interests for accounting
purposes.
 
TREATMENT OF OPTIONS
 
    In the merger, unexercised options representing "net option shares" will be
exchanged for MTS common stock. DSPT intends to treat the conversion of
incentive stock options into MTS common stock as a deemed exercise of the
incentive stock options, resulting in income recognition for U.S. federal
alternative minimum tax purposes, but not for federal regular income tax
purposes. Withholding
 
                                       36
<PAGE>
taxes will not be withheld with respect to the conversion of incentive stock
options into MTS common stock.
 
    Holders of nonqualified stock options to acquire DSPT common stock who have
their unexercised options converted into MTS common stock will recognize
ordinary income for income tax purposes which will be reported on their 1999
Form W-2, for employees, or Form 1099, for former employees and independent
contractors, in an amount equal to the value of the MTS common stock on the
merger closing date. Withholding taxes will apply with respect to wage income
recognized by employees and former employees.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
    The following contains a description of the material federal income tax
consequences of the merger to the holders of common stock. This summary relies
upon the opinions of Lindquist & Vennum P.L.L.P. and Gray Cary Ware &
Freidenrich LLP, and is based upon current provisions of the Internal Revenue
Code of 1986, existing regulations and current administrative rulings and court
decisions, all of which are subject to change. Any change, which may or may not
be retroactive, could alter the tax consequences to MTS, DSPT or the
stockholders of DSPT. No attempt has been made to comment on all federal income
tax consequences of the merger that may be relevant to particular holders,
including holders who are subject to special tax rules such as dealers in
securities, foreign persons, mutual funds, insurance companies, tax-exempt
entities, holders who are subject to the alternative minimum tax provisions of
the Internal Revenue Code, holders who acquired their shares in connection with
stock option or stock purchase plans or in other compensatory transactions,
holders who hold their shares as a hedge or as part of a hedging, straddle or
other risk reduction strategy, and holders who do not hold their shares as
capital assets. In addition, the following discussion does not address the tax
consequences of the merger under state, local and foreign tax laws or the tax
consequences of transactions effectuated prior to or after the merger, whether
or not such transactions are in connection with the merger. Accordingly, holders
of DSPT common stock are advised and expected to consult their own tax advisers
regarding the federal income tax consequences of the merger in light of their
personal circumstances and the consequences under state, local and foreign tax
laws.
 
    As a condition to the consummation of the merger, Lindquist & Vennum
P.L.L.P. and Gray Cary Ware & Freidenrich LLP must render tax opinions that the
merger will constitute a reorganization within the meaning of Section 368(a) of
the Internal Revenue Code. The tax opinions discussed in this section are
included as an exhibit to the registration statement of which this proxy
statement/prospectus is a part. Those opinions assume and are conditioned upon
the following:
 
    - the truth and accuracy of the statements, covenants, representations and
      warranties contained in the merger agreement, in the tax representations
      received from MTS, Badger and DSPT to support the tax opinions and in all
      other instruments and documents related to the formation, organization and
      operation of MTS, Badger and DSPT, and that no actions have been or will
      be taken which are inconsistent with such statements, descriptions and
      representations;
 
    - that original documents submitted to counsel are authentic, documents
      submitted to counsel as copies conform to the original documents, and that
      all of those documents have been, or will be by the effective time, duly
      and validly executed and delivered where due execution and delivery are a
      prerequisite to the effectiveness of those documents;
 
    - that all covenants contained in the merger agreement and the tax
      representations described above are performed without waiver or breach of
      any material provision of those covenants;
 
    - that any representation or statement made "to the best of knowledge" or
      similarly qualified is correct without those qualifications; and
 
                                       37
<PAGE>
    - that the merger will be consummated in accordance with the merger
      agreement, and without any waiver, breach or amendment of any of the
      material provisions of the merger agreement, will be effective under the
      applicable state law, and will be reported by MTS and DSPT on their
      respective federal income tax returns in a manner consistent with
      treatment of the merger as a reorganization.
 
    No ruling from the Internal Revenue Service has been or will be requested in
connection with the merger. In addition, stockholders of DSPT should be aware
that the tax opinions discussed in this section are not binding on the IRS and
no assurance can be given that the IRS will not adopt a contrary position or
that a contrary position would not be sustained by a court.
 
    Subject to these assumptions and limitations, it is the opinion of Lindquist
& Vennum P.L.L.P., tax counsel to MTS, and Gray Cary Ware & Freidenrich LLP, tax
counsel to DSPT that:
 
    (1) the merger will be treated for federal income tax purposes as a
       reorganization;
 
    (2) MTS, Badger and DSPT will each be a party to the reorganization;
 
    (3) MTS, Badger and DSPT will not recognize any gain or loss solely as a
       result of the merger;
 
    (4) stockholders of DSPT will not recognize any gain or loss upon the
       receipt of solely MTS common stock for their common stock, other than
       with respect to cash received in lieu of fractional shares of common
       stock;
 
    (5) the aggregate basis of the shares of MTS common stock received by a
       stockholder in the merger, including any fractional share deemed
       received, will be the same as the aggregate basis of the shares of DSPT
       common stock surrendered in exchange;
 
    (6) the holding period of the shares of MTS common stock received by a DSPT
       stockholder in the merger will include the holding period of the shares
       of DSPT common stock surrendered in exchange, provided that those shares
       of DSPT common stock are held as capital assets at the effective time of
       the merger; and
 
    (7) a stockholder of DSPT who receives cash in lieu of a fractional share
       will recognize gain or loss equal to the difference, if any, between a
       stockholder's basis in the fractional share and the amount of cash
       received. The gain or loss will be a capital gain or loss if the DSPT
       common stock is held by the stockholder as a capital asset at the
       effective time of the merger.
 
    DSPT stockholders should attach to their federal income tax returns for the
year of the merger a statement of all facts pertinent to the nonrecognition of
gain or loss upon the exchange of DSPT common stock for MTS common stock,
including the stockholder's tax basis in the stockholder's DSPT common stock and
a description of the MTS common stock received.
 
    Regardless of whether or not the merger qualifies as a reorganization, a
DSPT stockholder receiving MTS common stock would recognize income or gain to
the extent those shares are considered to be received in exchange for services
or property other than solely DSPT common stock. Gain would also be recognized
to the extent a DSPT stockholder is treated as receiving consideration other
than MTS common stock in exchange for the stockholder's DSPT common stock.
 
    A successful IRS challenge to the status of the merger as a reorganization
would result in a DSPT stockholder recognizing gain or loss with respect to each
share of DSPT common stock in an amount equal to the difference between the
stockholder's basis in such share and the fair market value, as of the effective
time of the merger, of the MTS common stock received in exchange. A
stockholder's aggregate basis in the MTS common stock received would equal its
fair market value, and the stockholder's holding period for the MTS common stock
would begin the day after the merger.

ANTICIPATED ACCOUNTING TREATMENT
 
    The merger is expected to be accounted for using the "pooling of interests"
method of accounting pursuant to Opinion No. 16 of the Accounting Principles
Board. The pooling of interests method of accounting assumes that the combining
companies have been merged from inception, and the historical consolidated
financial statements for periods prior to consummation of the merger are
restated as though the companies had been combined from inception. Either MTS or
DSPT may terminate the merger agreement if the merger cannot be accounted for as
a pooling of interests.
 
GOVERNMENTAL APPROVALS
 
    The merger is subject to review by the Department of Justice and the Federal
Trade Commission to determine whether it complies with applicable antitrust
laws. Under the provisions of the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, the merger may not be consummated until the waiting period specified
under the act has expired. MTS and DSPT filed notification reports, together
with requests for early termination of the waiting period, with the Department
of Justice and the Federal Trade Commission on April 6, 1999. These filings
commenced the 30-day waiting period. In letters dated April 20, 1999, the U.S.
Department of Justice, Antitrust Division requested that MTS and DSPT
voluntarily supply supplemental information concerning the merger. This request
is not a formal "second request" for additional information or documentary
materials under the Hart-Scott-Rodino Antitrust Improvements Act, but there can
be no assurance that a "second request" will not be issued. MTS and DSPT have
supplied some of the requested information and expect to supply further
information on a voluntary basis. If additional information or documents is
requested by these agencies, consummation of the merger could be delayed.
 
ABSENCE OF APPRAISAL RIGHTS
 
    Under Section 262 of the Delaware General Corporation Law, stockholders who
do not vote in favor of or consent to a merger are not entitled to appraisal
rights if the stock subject to such merger is listed on a national exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. and the
consideration to be received in such merger consists of stock listed on a
national securities exchange or designated as a national market system security
on an interdealer quotation system by the National Association of Securities
Dealers, Inc. Because the Nasdaq National Market is designated as such a system
and the DSPT common stock and MTS common stock are quoted on the Nasdaq National
Market, holders of DSPT common stock are not entitled to appraisal rights with
respect to the merger.
 
RESALE OF MTS COMMON STOCK
 
    The MTS common stock to be issued in connection with the merger will be
freely transferable, except that shares issued to any DSPT stockholder or
optionholder who is an affiliate of DSPT or who becomes an affiliate of MTS are
subject to restrictions on resale. An affiliate is defined generally as
including, without limitation, directors, executive officers and other persons
who control a company. Stockholders of DSPT who may be deemed to be affiliates
have executed agreements that prohibit the sale, transfer or other disposition
of their DSPT common stock or MTS common stock received by stockholders in the
merger, except in compliance with the requirements of federal securities laws
and pooling of interests requirements. See "Approval of the Merger and Related
Transactions--Affiliate Agreements" on page 36.

                     MATERIAL TERMS OF THE MERGER AGREEMENT
 
    The following description of the merger agreement describes the material
terms of the merger agreement. The full text of the merger agreement is attached
as Appendix A to this proxy statement/ prospectus and is incorporated by
reference. We encourage you to read the entire merger agreement.
 
EFFECTIVE TIME OF THE MERGER
 
    The merger will become effective when a certificate of merger is filed with
the Secretary of State of the State of Delaware. If all the conditions to the
merger contained in the merger agreement are satisfied or waived, we anticipate
the effective time will occur on the date of the special meeting or as soon as
practicable following the special meeting.
 
MERGER CONSIDERATION
 
    At the effective time of the merger, MTS will issue a total of 2,077,000
shares of its common stock in exchange for all outstanding shares of DSPT common
stock and outstanding options to purchase DSPT common stock. As a result, each
outstanding share of DSPT common stock and each "net option share" will be
exchanged for a fraction, the exchange ratio, of a share of MTS common stock
equal to 2,077,000 divided by the sum of outstanding DSPT shares and DSPT "net
option shares."
 
    - "Net option shares" will represent the number of DSPT shares subject to
      outstanding options less a number of shares with a value, based upon the
      implied DSPT "share value" at the time of the merger, equal to the
      aggregate exercise price. Unvested shares will be discounted using a
      method mutually agreeable to the companies. As of April 14, 1999, DSPT had
      options for 663,468 shares outstanding with a weighted average exercise
      price of $5.446.
 
    - The implied "DSPT share value" at the time of the merger will be
      determined by dividing (a) the market value of the 2,077,000 MTS shares of
      common stock issued in the merger plus the aggregate exercise price of the
      DSPT options by (b) the total number of DSPT shares outstanding plus DSPT
      shares subject to outstanding options.
 
    - Example. For example, assuming at the time of the merger that the market
      value of MTS' common stock is $13.00 and all of DSPT's outstanding options
      as of April 14, 1999 remain unexercised, each DSPT share outstanding and
      each "net option share" will receive 0.8037 of a share of MTS common
      stock. If the market value of MTS' common stock is $11.00 at the time of
      the merger, each "net option share" will receive 0.8209 of a share of MTS
      common stock.
 
    The exact exchange ratio will not be determined until closing and will
depend upon the market price of MTS common stock, the number of outstanding
shares of DSPT common stock, the number of DSPT shares subject to outstanding
options and the exercise prices of such options. Therefore, the actual exchange
ratio for the merger, the aggregate value of the 2,077,000 MTS shares of common
stock issued in the merger, and the allocation of the aggregate merger
consideration between DSPT stockholders and optionholders could be affected by:
 
    - increases or decreases in the market price of MTS common stock;
 
    - exercises of DSPT options and their related exercise prices; and
 
    - grants of additional DSPT options.
 
    DSPT has agreed in the merger agreement that it will not grant options for
more than 28,000 shares prior to the closing of the merger.
 
    The following table shows, for certain MTS stock prices at closing, the
exchange ratio for the merger, the implied value of a share of DSPT common
stock, the value of the aggregate merger consideration to be received by DSPT
stockholders and optionholders and the allocation of such
 
                                       40
<PAGE>
merger consideration between DSPT stockholders and optionholders. The amounts
shown in the table below are calculated assuming that the number of outstanding
shares of DSPT stock, the number of shares subject to outstanding options and
the related exercise prices of such options remain constant at April 14, 1999
levels prior to closing.

    The following table shows, at an MTS share price of $13.00, the effect on
the merger consideration if DSPT options for varying amounts of shares are
exercised with a weighted average exercise price of $5.446, which is the
weighted average exercise price of all options outstanding on April 14, 1999.
The actual values will depend on the actual exercise prices of the options, if
any, that are exercised. It is not possible to predict what the weighted average
exercise prices of such options will be. DSPT optionholders may exercise options
at any time until the effective time of the merger.

    The value of MTS common stock at the time of the special meeting, the date
of the completion of the merger, the date that stockholders eventually sell
shares of MTS common stock, or at any other time, may be significantly different
than the price of MTS common stock today. See "Market Price Data and Dividend
Policy" on page 15 and "Material Terms of the Merger Agreement--Merger
Consideration" on page 40. On April 27, 1999, the closing sale price of MTS
common stock was $11.50. DSPT stockholders should obtain recent market
quotations for MTS common stock and DSPT common stock and understand the
exchange ratio being offered in the merger.

                                       46
<PAGE>
    For purposes of the merger agreement, the term "superior proposal" means a
proposal for an alternative transaction that the DSPT board of directors
determines, reasonably and in good faith to be more favorable to DSPT's
stockholders than the merger. This determination must be made after consultation
with DSPT's financial advisors, taking into account the likelihood of
consummation of the alternative transaction, including, but not limited to, the
conditions to consummation and the consequences under the alternative
transaction of any material adverse effects or changes in DSPT.

BUSINESS OF DSPT
 
INTRODUCTION
 
    DSPT designs, develops, manufactures, markets and integrates high-speed
computer-automated instrumentation for measurement and control applications.
DSPT has two divisions, the transportation group, which focuses on powertrain
testing, and the lab group, which focuses on vehicle safety and component
testing, general data acquisition and signal analysis. Powertrain testing is
currently DSPT's largest market and major focus.
 
    On January 21, 1999, DSPT announced its strategic decision to relocate its
corporate headquarters to, and consolidate its transportation group operations
in Ann Arbor, Michigan in order to allow efficient operation of the
transportation group, its largest and most profitable business segment. DSPT
recorded a one-time pre-tax restructuring charge of $496,000 in the fourth
quarter of 1999 which consists of $306,000 in severance pay and $190,000 in
estimated idle facility and winding down costs in connection with the
restructuring.
 
    DSPT's products are used to gather and measure analog signals generated by
transducers and/or detectors which measure physical properties such as
temperature, pressure and acceleration. These products have been used primarily
in the transportation industry, in powertrain testing such as dynamometer
control and automotive combustion research, and vehicle impact and simulation
testing. Aerospace companies, universities and government-funded agencies use
DSPT's products in ultrasonics, chemical kinetics, plasma diagnostics,
spectroscopy, fusion research, explosives testing and vibration analysis.
 
    DSPT was incorporated in California in July 1982 and began operations in May
1984. DSPT reincorporated in Delaware in September 1997.
 
STRATEGY
 
    DSPT's strategy is to focus its resources on the transportation market as
DSPT's largest market. DSPT defines the transportation market as including the
following industries and segments:
 
    - major vehicle manufacturers and their suppliers;
 
    - the diesel industry, e.g., manufacturers of heavy trucks, farm and
      construction equipment and large stationary engines;
 
    - the fuels and lubricants industry;
 
    - small engine manufacturers; and
 
    - racing engine technology.
 
    DSPT believes that the fundamental factors of government environmental
regulation, global competition among vehicle manufacturers, and rapid
technological progress are expanding the demand for advanced turnkey powertrain
test solutions. Large domestic and international customers demand more custom
turnkey solutions that require more complex services. DSPT believes that
investments in this area are necessary and logical steps towards expanding its
share of the transportation market.
 
    To address its customers' needs in the transportation market, DSPT announced
its strategic decision in early fiscal 1997 to focus more heavily and expand its
capabilities on the services side of the business, continue development of new
products with higher levels of capability and integration, and take a more
aggressive approach to marketing with the goal of becoming a full-service
company capable of manufacturing and providing turnkey integration of DSPT's
products.
 
                                       49
<PAGE>
    DSPT also continues to invest in the development of data acquisition
products. In fiscal 1999, DSPT introduced ADAPT-CAS, its new combustion analysis
system, BaseLine ADAPT, its new, low-cost dynamometer control system, and
software enhancements to ADAPT-DAC, DSPT's primary dynamometer control system.
 
    DSPT entered into a Strategic Alliance Agreement dated February 26, 1995
with FEV Motorentechnik GmbH & Co. KG. As of February 26, 1999, FEV beneficially
owned approximately 12.5% of DSPT outstanding common stock. DSPT entered into
the strategic relationship with FEV in order to combine resources, technology
and distribution for joint product development and distribution within certain
territories. Under the terms of the agreement, DSPT and FEV have agreed to
jointly develop and manufacture certain products as well as act as sole
distributors of each other's pre-existing products within certain respective
territories, and to act as strategic partners with respect to distribution for
other parts of the world. DSPT, MTS and FEV have entered into an agreement which
will supersede this agreement effective upon the merger. See "Information with
Respect to MTS" on page 65.
 
PRODUCTS AND CUSTOMERS
 
    DSPT manufactures and markets data acquisition and control products in the

products are Boeing Commercial Airplane, Naval Air Warfare Center, Telogy,
Stanford Linear Accelerator and Ethyl Corporation.
 
MANUFACTURING AND SUPPLIERS
 
    DSPT manufactures its products from components and prefabricated parts such
as integrated circuits, printed circuit boards, power supplies and enclosures
manufactured by others. Manufacturing operations consist of assembly of printed
circuit boards, power supplies and crates, system integration and final testing.
Materials and components used by DSPT in manufacturing are available primarily
from domestic sources. Where possible, DSPT buys from multiple sources to avoid
dependence on any single supplier. However, certain custom analog devices are
only available from a limited number of suppliers.
 
MARKETING AND SALES
 
    In the United States, DSPT primarily sells and services its products through
its own sales and service organizations located in Michigan and California. In
Canada, Western Europe, Korea and Japan, DSPT sells its products through
independent distributors through whom DSPT provides technical and administrative
assistance. For its transportation market products, DSPT distributes its
products through FEV in Europe except for the United Kingdom. In the United
Kingdom, DSPT operates a sales and customer support subsidiary for its
powertrain testing products. DSPT's standard terms of sale generally require
payment within 30 days of shipment.
 
    The following customers accounted for over 10% of fiscal 1999 net sales:
General Motors accounted for 15%, Sverdrup for 14% and Engelhard for 12%. In
fiscal 1998, General Motors accounted for 21% of net sales and Hyundai Motor
accounted for 14% of net sales. General Motors accounted for 18% of net sales in
fiscal 1997. No other customer accounted for 10% or more of DSPT's net sales in
fiscal years 1999, 1998 or 1997. Sales of DSPT products through DSPT's
relationship with FEV during fiscal 1999 were approximately $1,248,000 or
approximately 5% of DSPT's total net sales.
 
    Export sales, primarily to the United Kingdom, Western Europe, and the Far
East, accounted for approximately 20%, 35% and 32% of sales in 1999, 1998 and
1997, respectively.
 
    At January 31, 1999, DSPT had an order backlog of approximately $4,800,000
compared to a backlog of approximately $11,500,000 at January 31, 1998, and
approximately $9,500,000 at January 31, 1997. Backlog consists of orders
believed by management to be firm and scheduled for delivery within twelve
months. However, most orders can be rescheduled or canceled by customers without
significant penalty. In addition, backlog is dependent on the timing of orders,
particularly large orders, and on seasonal spending for capital requirements.
Accordingly, backlog at January 31, 1999, or at any other date, may not be
indicative of prospective sales.
 
SERVICE AND WARRANTY
 
    DSPT maintains a telephone hotline staffed with qualified technicians to
respond to service calls. Most servicing is performed at its facilities in
Fremont, California and Ann Arbor, Michigan.
 
                                       52
<PAGE>
    DSPT generally extends a one-year warranty for its products. Warranty costs
have been nominal to date.
 
RESEARCH AND DEVELOPMENT
 
    DSPT's ability to compete successfully in an industry subject to rapid
technological change depends on, among other things, its ability to anticipate
and respond to such change. Accordingly, DSPT is committed to a high level of
research and development activity. In 1999, the principal products introduced
were the transportation group's RedLine ADAPT-CAS, its new combustion analysis
system, BaseLine ADAPT, a lower cost dynamometer controller and several software
enhancements and upgrades to ADAPT-DAC system, its primary dynamometer control
system. In 1999, the lab group introduced several new software add-ons which
have helped broaden the market for its signal acquisition products. DSPT expects
that in 2000 research and development activities will focus primarily on
software development for new products and product enhancements.
 
    DSPT incurred expenditures for research and development of $2,765,000 in
fiscal 1999, $2,352,000 in fiscal 1998 and $2,203,000 in fiscal 1997,
representing 11%, 11%, and 12% of total sales in each such period. In accordance
with the Statement of Financial Accounting Standards No. 86 which requires the
capitalization of software development costs incurred subsequent to establishing
the technological feasibility of producing the finished software product. DSPT
capitalized $522,000, $517,000, and $630,000 in fiscal 1999, 1998 and 1997,
respectively.
 
COMPETITION
 
    Competition, from both U.S. and foreign competitors, is strong and active.
Some of these competitors are substantially larger companies with greater
resources. DSPT management believes that these companies include AVL located in
Graz, Austria, and Sverdrup, a system integrator based in Tennessee.
 
    DSPT competes primarily on the basis of product diversity, features and
functions, price/ performance, flexibility, and technical support. In addition,
DSPT believes that an additional competitive factor in the automotive market is
its installed base in the United States. DSPT believes that it competes
favorably with respect to all these factors. Systems integration experience and
ability is increasingly a factor in large system orders and DSPT believes that
it has the personnel and the resources to compete in this area, although many of
its competitors are substantially larger with greater resources.
 
PROPRIETARY RIGHTS
 
    DSPT relies upon a combination of copyright, trade secret laws and
non-disclosure and licensing agreements to establish and maintain its
proprietary rights to its products. The laws of foreign countries may not
protect DSPT's proprietary rights to the same extent as do the laws of the
United States. Although DSPT continues to implement protective measures and
intends to defend its proprietary rights, these measures may not be successful.
DSPT believes, however, that, because of the rapid pace of technological change
in the automated test, measurement and control industries, the legal protections
for its products are less significant factors in DSPT's success than the
knowledge, ability, and experience of DSPT's employees, the frequency of product
enhancements and the timeliness and quality of support services provided by
DSPT.
 
    DSPT is subject to the risk of adverse claims and litigation alleging
infringement of intellectual property rights. Technology used in DSPT's products
is licensed from third parties on a non-exclusive basis. These license
agreements generally require DSPT to pay royalties and to fulfill
confidentiality obligations in order to maintain the licenses. The termination
of any of these licenses may have a material adverse effect on DSPT's
operations. While it may be necessary or desirable in the future to
 
                                       53
<PAGE>
obtain other licenses relating to one or more of its products or relating to
current or future technologies, DSPT may not be able to do so on commercially
reasonable terms.
 
EMPLOYEES
 
    DSPT had 158 employees at January 31, 1999. Of these employees, 107 worked
in manufacturing and engineering, 29 in marketing and sales and 22 in
administration. None of DSPT's employees is represented by a labor union and
there has never been a disruption of operations due to labor dispute.
 
PROPERTIES
 
    DSPT's facilities consist of approximately 28,000 square feet of space in
Fremont, California and approximately 26,000 square feet of space in Ann Arbor,
Michigan which are leased under operating leases. The Fremont facility lease
provides for monthly rent payments of $15,146 through October 1998 and $35,388
from November 1998 through lease expiration on July 1999. DSPT plans to move its
lab group to a smaller location when the lease expires.
 
    The Ann Arbor facility leases consist of:
 
    - A seven-year lease for one building which expires in January 2000,
      providing for annually increasing monthly rental payments reaching $10,257
      during the seventh year. DSPT expects to move out of this facility when
      the lease expires.
 
    - A 31-month lease for another building which expires in June 1999, with
      monthly rental payments of $4,308 from December 1996 through May 1998 and
      increasing to $4,602 per month thereafter. DSPT plans to extend its lease
      on this facility until it is able to move into its new facility.
 
    - A facility sublease commencing October 1998, providing for monthly rental
      payments of $4,696, and renewable annually each June until June 2002. If
      DSPT does not renew the lease, DSPT is responsible to pay the lessor a
      one-time payment to cover the unamortized costs of the tenant
      improvements. DSPT expects to renew its lease for another year in June
      1999.
 
    DSPT is obligated to pay real estate taxes, insurance and maintenance
expenses associated with the leased facilities.
 
    DSPT is in the process of constructing a new 57,200 square foot facility
located in Ann Arbor, Michigan, which will house its corporate headquarters and
transportation group. Under the terms of the construction contract, DSPT is
obligated to pay the contractor $3,750,000 for the construction of the new
facility which is expected to be completed sometime during the fall of 1999.
Management believes that the new facilities will be adequate for the company
over the next two to three years.
 
    DSPT also owns a condominium located in Ann Arbor, Michigan.

    For accounting purposes, DSPT changed to a 52/53 week convention with the
fiscal year ending on the Sunday nearest the end of January effective on the
fiscal year beginning February 1, 1997. However, for financial reporting
purposes, each fiscal quarter or year is presented as if it ended on the last
day of such period. The number of days covered in each year used in the
period-to-period comparisons are essentially the same with 1999 and 1998 having
364 days and 1997 having 366 days.
 
    OVERVIEW.  One of the major trends occurring in the transportation industry,
DSPT's largest market, is that large customers are demanding custom turnkey
solutions that require more complex integration services. DSPT believes that
investments in this area are necessary to expand its share of the transportation
market. Starting in 1997, DSPT invested heavily in developing significant
service capabilities in the areas of custom manufacturing, system integration,
project engineering/management, installation and commissioning with the goal of
becoming a full-service company capable of manufacturing and providing turnkey
integration of its products. DSPT's turnkey solutions, which combine our
products and integration services, have provided DSPT's growth in the last three
years.
 
    REVENUES AND SALES BACKLOG.  Revenues were $25,396,000, $22,038,000 and
$17,987,000 in 1999, 1998 and 1997, respectively, with annual revenue growth of
15% from 1998 to 1999 and 23% from 1997 to 1998. Revenue growth during 1999 and
1998 was principally driven by several large orders, contracts greater than
$1,000,000, for the transportation group turnkey RedLine data acquisition and
control systems that increased sales backlogs to $9,500,000 at January 31, 1997
and to $11,500,000 at January 31, 1998. In addition, the introduction of new
products in the lab group slowed the decline in revenues for the lab group from
1997 to 1998 and resulted in a slight increase from 1998 to 1999.
 
    Overall revenue growth slowed in 1999 and sales backlog decreased to
$4,800,000 at January 31, 1999, as the total dollar amount of large orders for
transportation group products dropped significantly in 1999 compared to 1998,
primarily due to delays in budgetary approvals from several major customers, as
well as the delay in the introduction of DSPT's new RedLine combustion product,
Redline ADAPT-CAS. In addition, revenues and sales bookings from the Asian
market for Transportation Group products fell dramatically, reflecting the
economic conditions in that region.
 
    The revenue increase in 1997 compared to 1996 was principally due to
continued increase in demand for the transportation group products and services
associated with RedLine ADAPT-DAC.
 
    Product revenues amounted to $21,349,000, $19,114,000 and $16,154,000 in
1999, 1998 and 1997, respectively. Product revenues grew by 12% in 1999 from
1998, and by 18% in 1998 and 1997. Product
 
                                       56
<PAGE>
revenue growth in 1999 and 1998 was primarily due to the large orders received
for its turnkey solutions in 1998 and 1997. The decrease in the rate of product
revenue growth experienced in 1999 is attributable to the factors described
above.
 
    Service revenues amounted to $4,047,000, $2,924,000 and $1,833,000 in 1999,
1998 and 1997, respectively. Service revenues grew by 38% in 1999 from 1998, and
by 59% in 1998 from 1997. Service revenues amounted to 16%, 13% and 10% of total
revenues in 1999, 1998 and 1997, respectively. The growth in service revenues in
all periods reflects an increase in integration services revenues as part of
turnkey system solutions introduced in 1997 to fill the growing need from DSPT's
large transportation group customers. In addition, maintenance contracts and
training services also increased as product revenues increased.
 
    GROSS PROFIT.  Gross profit percentage decreased to 53% in 1999 compared to
54% in 1998 and 56% in 1997. Gross profit percentage is subject to change due to
various factors, including variation in product mix, changes in component costs
and revenue levels. As anticipated in 1999 and 1998, the decrease in gross
profit percentages is a result of product mix shift towards lower margin
transportation group turnkey RedLine systems. This shift in product mix
decreased the gross profit percentage in the transportation group segment from a
high of 56% in 1997 to 52% in 1998 and 51% in 1999. These percentages were
offset partially by the increasing gross profit margins for the lab group that
went from 58% in 1997 to 62% in 1998 and 68% in 1999. The increase in margins in
the lab group was primarily due to a shift in product mix to higher margin new
products.
 
    Information regarding gross margins related to product sales and service
sales are not provided separately as such information is not readily available
from DSPT's management information system.
 
    RESEARCH AND DEVELOPMENT.  DSPT invests in new product and application
developments in both the transportation group and lab group. The majority of the
research and development expenses in all the periods presented were for the
transportation group which introduced several new products and enhancements
during the last three years.
 
    Research and development expenses during the last three years remained at
11-12% of revenues. The increase in absolute dollars in 1999 compared to 1998
was primarily due to the addition of engineering consultants in the short term
to accelerate the completion of certain product development projects, including
RedLine which was behind schedule. DSPT anticipates research and development
expenses to continue to increase in absolute dollars as it continues to add
personnel to staff its development projects. However, it is expected that
research and development expenses will remain at approximately 11% of net sales.
 
    MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES.  Marketing, general and
administrative expenses increased in absolute dollar amounts by $1,095,000, or
16% in 1999 from $6,916,000 in 1998. As a percentage of sales, these expenses
increased slightly to 32% in 1999 compared to 31% in 1998. The increase in
spending in 1999 compared to 1998 was due to increased sales and marketing
expenses, including the hiring of additional marketing personnel and increased
advertising and sales collateral budgets. These expenses were primarily incurred
to permit increased focus on industrial manufacturers and a broad range of
transportation industry equipment suppliers. DSPT also increased trade show
expenses to introduce new products and incurred higher administrative support
costs in 1999.
 
    Marketing, general and administrative expenses increased in absolute dollar
amounts by 3% in 1998 compared to 1997, and decreased as a percentage of sales
to 31% in 1998 from 37% in 1997. The increase in absolute dollars was a result
of DSPT hiring additional sales and applications personnel to address the
increased level of sales opportunities primarily for turnkey systems. The
decrease in the percentage of sales was a result of increased revenues.
 
    RESTRUCTURING COSTS.  On January 21, 1999, DSPT announced its strategic
decision to relocate its corporate headquarters to, and consolidate its
transportation group operations in, Ann Arbor, Michigan
 
                                       57
<PAGE>
in order to allow efficient operation of the transportation group, its largest
and most profitable business segment. DSPT recorded a one-time, pre-tax
restructuring charge of $496,000 in the fourth quarter of 1999 which consists of
$306,000 in severance pay and $190,000 in estimated idle facility and winding
down costs.
 
    DSPT expects that after the move and consolidation is complete sometime in
fiscal 2000, earnings will benefit from a lower cost structure and improved
operating efficiencies. Manufacturing, sales and service for the transportation
group will be consolidated with corporate headquarters into a single,
company-owned facility in Ann Arbor.
 
    OTHER INCOME.  Other income, net of interest expense in 1999 was essentially
unchanged at $221,000 compared to $225,000 in 1998, and increased from $123,000
in 1997. On average, DSPT had much higher available cash to invest or to take
advantage of vendor early payment discounts in 1999 and 1998 than in 1997.
 
    INCOME TAXES.  The effective tax rate computed for 1999 was 37% compared to
40% in 1998 and 33% in 1997. The lower tax rate in 1999 versus 1998 reflect
primarily the higher research and development credits and lower state tax rates.
 
    The higher tax rate in 1998 compared to 1997 reflect 1998's higher domestic
income contribution, higher state income taxes and lower research and
development tax credits compared to 1997. Domestic tax rates historically have
been higher than DSPT's foreign subsidiary's tax rates.
 
    Factors that may affect the tax rates include research and development tax
credits, differences in state tax rates, software capitalization levels and
foreign income contributions.
 
    NET INCOME.  As a result of the factors discussed above, net income
decreased in absolute dollars to $1,582,000, or $.64 per diluted share in 1999,
from $1,646,000, or $.68 per diluted share in 1998. 1997 net income was
$914,000, or $.40 per diluted share.
 
    LIQUIDITY AND CAPITAL RESOURCES
 
    CASH FLOWS.  During 1999, operating activities used $724,000 of cash,
compared with cash generated of $3,915,000 and $929,000 in 1998 and 1997,
respectively. The cash used in 1999 for operating activities was largely due to
the application of customer prepayments against receivables and to increased
accounts receivable brought about primarily by high shipments in the last month
of the year end. The major uses of cash in investing and financing activities
included additions to property and equipment, investment in software development
and the repurchase of DSPT's common stock on the open market.
 
    Capital expenditures for property and equipment additions totaled $1,743,000
in 1999, $407,000 in 1998, and $1,015,000 in 1997. Major capital expenditures in
1999 included the purchase of land for the Ann Arbor building site and
construction-in-progress costs for the new 57,200 square foot facility. DSPT
purchased the land late in the second quarter of 1999 in anticipation of growth
over the next three to five years. Due to the rising building lease costs in the
Ann Arbor, Michigan area, DSPT found that it would cost less to own its own
facility. Building construction costs along with furniture, fixtures and
equipment is currently estimated at $4,600,000. DSPT anticipates that the
construction and eventual mortgage of the building will be financed through the
Michigan Strategic Fund industrial bond financing. In August 1998, the Michigan
Strategic Fund adopted an inducement resolution for a loan not to exceed
$5,900,000 for DSPT. The bond issuance is pending negotiations between DSPT,
Michigan Strategic Fund and DSPT's bank. As part of the financing, DSPT's bank
will be expected to issue a letter of credit and will require a guarantee from
MTS. DSPT expects the financing to be completed in May 1999.
 
                                       58
<PAGE>
    DSPT has secured a building contractor to build the first phase on the
property, and began construction of the first phase in February 1999. Based on
DSPT's current growth plans, DSPT believes that the building site is sufficient
to allow DSPT to grow over the next three to five years.
 
    SHARE REPURCHASE PLAN.  In May 1998, DSPT announced plans to repurchase up
to 225,000 shares of its outstanding common stock, which represents
approximately 10% of its shares, at prevailing market prices because it deemed
the repurchase a good investment. DSPT terminated the repurchase plan in March
1999 in connection with the board of directors' approval of the proposed merger
between DSPT and MTS. As of January 31, 1999, the DSPT had repurchased
approximately 51,000 shares on the open market for an aggregate amount of
$397,000, or $7.72 per share. As a result of the small number of shares of
repurchased common stock through January 31, 1999, the repurchase had minimal
effect on net income per share. DSPT made no further common stock repurchases
after January 31, 1999.
 
    FOREIGN CURRENCIES.  DSPT denominates substantially all of its transactions
in U.S. currency other than transactions by its foreign subsidiary. The assets
and liabilities of the Company's foreign subsidiary is denominated in the
country's local currency and translated at the year-end rate of exchange. The
related income statement items are translated at the average rate of exchange
for the year. The resulting translation adjustments are excluded from income and
reflected as a separate component of shareholders' equity. Realized and
unrealized exchange gains or losses arising from transaction adjustments are
reflected in operations and are not material.
 
    WORKING CAPITAL.  Working capital at January 31, 1999 was $8,276,000
compared to $8,173,000 at the beginning of the fiscal year, while the current
ratios stood at 2.8 to 1.0 at January 31, 1999 and at 2.5 to 1.0 at January 31,
1998. DSPT has a $4,000,000 secured bank line of credit with no balance
outstanding at January 31, 1999. DSPT currently anticipates that internally
generated funds, bank borrowings and anticipated revenue bonds will be
sufficient to satisfy its anticipated operating needs over the foreseeable
future.
 
    Management believes that inflation has not had a material effect on DSPT's
operations or financial condition.
 
    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
    DSPT management believes that the market risk associated with DSPT's market
risk sensitive instruments as of January 31, 1999 is not material, and
therefore, disclosure is not required.
 
    YEAR 2000 COMPLIANCE
 
    DSPT has an informal initiative in place to address Year 2000 issues and
risks. The five elements of the initiative can be summarized as follows:
 
    - product readiness;
 
    - internal infrastructure readiness;
 
    - facilities readiness;
 
    - supplier and vendor readiness; and
 
    - DSPT's contingency plan.
 
    PRODUCT READINESS.  DSPT's products perform functions related to acquiring
data from tests of other companies' products and do not perform date
calculations and, therefore DSPT does not consider Year 2000 issues and risks
related to its products to be significant. All products sold by DSPT since the
beginning of calendar 1998 have been tested by DSPT and determined to be Year
2000 compliant. DSPT has contacted all of its significant customers and informed
them that prior versions of
 
                                       59
<PAGE>
DSPT products may not be Year 2000 compliant. Customers with earlier versions of
DSPT products, other than some former DSPT products which are obsolete, may
upgrade at the cost of an annual maintenance contract to assure compliance.
 
    INTERNAL INFRASTRUCTURE READINESS.  DSPT has also reviewed its internal
management information systems, billing, outside payroll and other information
service functions critical to its operations and determined the nature and
extent of any Year 2000 issues related to such functions. DSPT's management
information systems, billing and outside payroll systems are run on software
provided by third party vendors. DSPT has obtained certifications from each of
such vendors that those systems have been tested and are Year 2000 compliant.
DSPT has a small number of noncompliant personal computers which will be phased
out of use during DSPT's consolidation of the transportation group to Ann Arbor.
 
    FACILITIES READINESS.  DSPT has conducted a limited review of its
facilities, including air conditioning, heating and other facilities related
systems, and has determined that its facilities are not Year 2000 compliant.
DSPT's California lease expires at the end of July 1999 and DSPT will relocate
the remaining operations being conducted in Fremont, California to a new
facility in the same area. DSPT expects to consolidate all of its operations in
Michigan into a new company-owned facility before the end of calendar 1999. As a
term and condition to entering into any new lease or building construction, DSPT
is requiring its lessor/building contractor to certify that the premises are
Year 2000 compliant.
 
    SUPPLIER AND VENDOR READINESS.  DSPT does not have any formal plan for
addressing Year 2000 compliance with its suppliers and vendors. DSPT has
received voluntary certification of Year 2000 compliance from many of its
existing suppliers and vendors who are critical to DSPT's operations. DSPT is in
the process of selecting new suppliers of most components and new assembly
houses for transportation group products as a result of the consolidation of its
transportation group operations in Ann Arbor, Michigan. DSPT has made the
receipt of Year 2000 compliance certification a term and condition of entering
into any new relationship with suppliers and vendors. DSPT intends to seek
certification of Year 2000 compliance from any remaining existing suppliers and
vendors critical to its operations beginning in May or June, 1999. DSPT expects
to concentrate on its suppliers of circuit boards, limited source vendors and
outside assembly houses for such third party products. DSPT expects to have the
supplier/vendor certification project complete by the fall of 1999.
 
    CONTINGENCY PLANNING.  DSPT does not consider the risks associated with Year
2000 issues to be significant to DSPT. DSPT has begun outlining the measures
that it can take in January 2000 to minimize any Year 2000 related problems.
Such measures include the following:
 
    - developing alternate supplier relationships;
 
    - stocking critical inventory items; and
 
    - stocking critical alternate parts and components.
 
    DSPT has also done the following with respect to Year 2000 issues and
compliance: notified its significant customers regarding the need to update
DSPT's older products for Year 2000 compliance; determined a course of action
for phasing out noncompliant end user computers; and implemented policies
regarding Year 2000 compliance with new suppliers and vendors and new landlords.
DSPT also expects to implement a more formal policy with respect to existing
suppliers and vendors who are critical to its operations. DSPT's costs to date
in addressing Year 2000 issues have not been significant, and DSPT expects that
any future costs will be immaterial.

    employment throughout the vesting period. The amounts reflected in the table
    may not necessarily be achieved. One share of stock purchased at $8.125 in
    fiscal 1999 would yield profits of approximately $5.11 per share at 5%
    appreciation over ten years, or approximately $12.95 per share at 10%
    appreciation over the same period.

                        INFORMATION WITH RESPECT TO MTS
 
AGREEMENT WITH FEV
 
    On March 21, 1999, MTS entered into a reciprocal distribution and licensing
agreement with FEV Motorentechnik GmbH, DSPT's strategic alliance partner, and
DSPT. This agreement will become effective only upon the closing of the merger
and will supersede the current strategic alliance agreement between FEV and DSPT
if the merger is consummated. It provides for the reciprocal distribution by MTS
and DSPT, as a group, and FEV of engine testing instruments and systems
developed and produced by the other party within certain designated geographical
territories. The agreement also provides for the licensing of specified products
by each party to the other for manufacture and distribution by the licensee
within its territory. In addition, FEV agreed that, pending the consummation of
the merger, it will not be deemed a "competitor" for purposes of the existing
strategic alliance agreement.
 
    MTS considers this new agreement with FEV to be an important alliance which
will provide an opportunity to increase the speed of customers' engine design
processes. It also believes that the agreement will link MTS' mechanical and
systems skills, DSPT's data acquisition and analysis strengths and FEV's engine
design capabilities.
 
BACKLOG
 
    On January 25, 1999, MTS issued a press release announcing that, due to the
timing of customer deliveries in its backlog, MTS is projecting lower revenue
than planned in the near term. MTS expects that this projection is likely to
reduce net income in MTS' second fiscal quarter of 1999 to a level only slightly
better than the results of its first fiscal quarter for the same year. MTS
expects, however, to recover this projected earnings shortfall in the second
half of its current fiscal year.

              COMPARISON OF RIGHTS OF HOLDERS OF MTS COMMON STOCK
                        AND HOLDERS OF DSPT COMMON STOCK
 
DESCRIPTION OF MTS CAPITAL STOCK
 
    The following describes of the material provisions of the articles of
incorporation and bylaws of MTS. MTS' articles of incorporation and bylaws are
included as exhibits to the documents incorporated by reference registration
statement of which this proxy statement/prospectus is a part.
 
    MTS COMMON STOCK
 
    MTS is authorized to issue 64,000,000 shares of common stock, par value $.25
per share. As of December 31, 1998, there were 18,626,853 shares of MTS common
stock issued and outstanding and approximately 1,760 holders of record of MTS
common stock. The holders of MTS common stock are entitled to one vote for each
share of common stock held on all matters submitted to a vote of shareholders
and have cumulative voting rights in the election of directors. The holders of
MTS common stock are entitled to receive ratably such dividends, if any, as may
be declared by the MTS board of directors out of legally available funds. In the
event of liquidation, dissolution or winding up of MTS, the holders of MTS
common stock are entitled to share ratably in all assets of MTS. The holders of
MTS common stock have no preemptive, subscription, redemptive or conversion
rights. The outstanding shares are fully paid and nonassessable.
 
    TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the MTS common stock is Norwest Bank
Minnesota, N.A.
 
COMPARATIVE RIGHTS OF MTS AND DSPT STOCKHOLDERS
 
    If the merger is consummated, the stockholders of DSPT will become
shareholders of MTS. The rights of the shareholders of MTS are governed by MTS'
amended and restated articles of incorporation, as amended, its bylaws and the
Minnesota Business Corporation Act. The rights of the stockholders of DSPT are
governed by DSPT's certificate of incorporation, its bylaws and the Delaware
General Corporation Law. The following is a brief summary of the primary
differences between the rights of MTS shareholders and the rights of DSPT
stockholders.
 
    CLASSIFICATION, REMOVAL AND ELECTION OF DIRECTORS
 
    The bylaws of MTS and DSPT provide that the number of directors of both
companies is determined by resolution of their respective boards of directors.
Newly created MTS directorships resulting from an increase in the authorized
number of directors may be filled by a two-thirds vote of the directors then in
office and any vacant directorships may be filled by a majority of the directors
then in office. Newly created and vacant DSPT directorships may be filled by a
majority of the directors then in office. Any director of either company may be
removed, with or without cause, by the holders of a majority of the shares
entitled to vote at an election of directors. Neither MTS' articles of
incorporation nor DSPT's certificate of incorporation provide for a classified
board of directors.
 
    VOTING RIGHTS
 
    MTS' and DSPT's governing documents both provide for cumulative voting
rights in the election of directors.
 
    Cumulative voting permits the holder of each share of stock entitled to vote
in the election of directors to cast that number of votes which equal the number
of directors to be elected. The holder may allocate all votes represented by a
share to a single candidate or may allocate those votes among
 
                                       66
<PAGE>
as many candidates as he chooses. Thus, a shareholder with a significant
minority percentage of the outstanding shares may be able to elect one or more
directors if voting is cumulative.
 
    PREFERRED STOCK
 
    DSPT's certificate of incorporation provides that shares of preferred stock
may be issued with terms, preferences and rights determined by DSPT's board of
directors without stockholder approval. MTS is not authorized to issue preferred
stock.
 
    STOCKHOLDER VOTE REQUIRED FOR CERTAIN TRANSACTIONS
 
    Neither MTS' nor DSPT's governing documents contain any provisions that
would require greater than a majority of its respective stockholders to approve
mergers, consolidations, sales of a substantial amount of assets or other
similar transactions.
 
    RIGHT TO CALL SPECIAL MEETING OF STOCKHOLDERS
 
    Under MTS' and DSPT's bylaws, special meetings of stockholders may be called
by the board of directors, the chairman of the board, or holders of 10% or more
of the outstanding voting power. MTS' bylaws also require the secretary of the
company to call a special meeting upon the written request of two or more
directors.
 
    ADVANCE NOTICE OF STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS
 
    Under MTS' and DSPT's bylaws, advance notice is required of stockholder
proposals or director nominations to be considered at a meeting of the
stockholders.
 
    ACTION BY WRITTEN CONSENT
 
    Minnesota law provides that any action of the shareholders of a Minnesota
corporation may be taken without a meeting if a written consent is signed by all
of the holders of outstanding voting stock of the corporation. DSPT's bylaws
provide that any action of its stockholders may be taken without a meeting,
without prior notice and without a vote, if a written consent is signed by the
holders of outstanding stock having the minimum number of votes that would be
necessary to authorize or take the action at a stockholder meeting. Prompt
notice of the taking of any corporate action without a meeting by less than
unanimous consent shall be given to those DSPT stockholders who have not
consented in writing.
 
    AMENDMENT OF GOVERNING DOCUMENTS
 
    Minnesota law provides that an amendment to the articles of incorporation
requires the affirmative vote of the holders of a majority of the shares present
and entitled to vote unless a larger affirmative vote is required by the
corporation's articles. MTS' articles of incorporation do not contain any
provisions that require a larger affirmative vote in order to amend its
articles.
 
    Delaware law provides that an amendment to the certificate of incorporation
requires the affirmative vote of the holders of a majority of the shares
entitled to vote unless the corporation's certificate requires a greater or
lesser number for approval. DSPT's certificate of incorporation does not contain
any provision requiring a different number for approval.
 
    The MTS bylaws provide that the MTS board of directors has the power to make
and alter the bylaws, subject to the power of the MTS shareholders to change or
repeal the bylaws.

    The DSPT bylaws provide that the DSPT board of directors have the power to

    BUSINESS COMBINATIONS AND CONTROL SHARE ACQUISITIONS
 
    MTS is governed by Sections 302A.671 and 302A.673 of the Minnesota Business
Corporation Act. In general, Section 302A.671 provides that the shares of a
corporation acquired in a "control share acquisition" have no voting rights
unless voting rights are approved in a prescribed manner. A control share
acquisition is an acquisition, of beneficial ownership of shares that would,
when added to all other shares beneficially owned by the acquiring person,
entitle the acquiring person to have voting power of 20% or more in the election
of directors. In general, Section 302A.673 prohibits a public Minnesota
corporation from engaging in a "business combination" with an "interested
shareholder" for a period of four years after the date of the transaction in
which the person became an interested shareholder, unless the business
combinations in approved in a prescribed manner. A business combination includes
any merger, asset sale or other transaction resulting in a financial benefit to
the interested shareholder. An interested shareholder is a person who is the
beneficial owner of 10% or more of the corporation's voting stock or who is an
affiliate or associate of the corporation and at any time within four years
prior to the date in question was the beneficial owner of 10% or more of the
corporation's voting stock. These provisions of the Minnesota law could delay,
defer or prevent a change in control of MTS.
 
    Section 203 of the Delaware General Corporation Act provides that a
corporation may not engage in any business combination with any interested
stockholder for a period of three years following the date that such shareholder
became an interested stockholder unless
 
    - prior to the date the stockholder became an interested stockholder the
      board of directors approved the business combination or the transaction
      which resulted in the stockholder becoming an interested stockholder;
 
    - upon consummation of the transaction which resulted in the stockholder
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transaction commenced, excluding for purposes of determining the
      number of shares outstanding, those shares owned by persons who are
      directors and also officers and shares owned by employee stock plans in
      which employee participants do not have the right to determine
      confidentially whether shares held subject to the plan will be tendered in
      a tender or exchange offer; or
 
    - the business combination is approved by the board of directors and
      authorized by 66 2/3% of the outstanding voting stock which is not owned
      by the interested stockholder. An interested stockholder means any person
      that is the owner of 15% or more of the outstanding voting stock; however,
      the statute provides for certain exceptions to parties who otherwise would
      be designated interested stockholders.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders of DSP Technology Inc.:
 
    We have audited the accompanying consolidated balance sheets of DSP
Technology Inc. and subsidiaries as of January 31, 1999 and 1998, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the three years in the period ended January 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of DSP Technology
Inc. and subsidiaries as of January 31, 1999 and 1998, and the consolidated
results of their operations and their consolidated cash flows for each of the
three years in the period ended January 31, 1999, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BUSINESS.  The Company designs, develops, manufactures, markets and
integrates high-speed computer-automated instrumentation for measurement and
control applications. The Company has two groups, the Transportation Products
Group, which focuses on powertrain testing, and the Lab Products Group, which
focuses on vehicle safety and component testing and general data acquisition and
signal analysis. The Company's principal markets are in the United States,
United Kingdom, Western Europe, and the Far East. Powertrain testing is
currently the Company's largest market and major focus.
 
    The Company's fiscal year ends on the Sunday nearest to January 31. However,
for financial statement purposes, each fiscal year is presented as if it ended
on January 31.
 
    PRINCIPLES OF CONSOLIDATION.  The consolidated financial statements include
the accounts of the Company and its subsidiaries. All significant intercompany
accounts and transactions have been eliminated.
 
    INVENTORIES.  Inventories are stated at the lower of cost (first-in,
first-out) or market. The Company periodically reviews its inventories for
potential slow-moving or obsolete items and writes down specific items to net
realizable value as appropriate.
 
    REVENUE RECOGNITION.  The Company recognizes revenue primarily upon shipment
when the product need only be manufactured and delivered. Revenue on contracts
requiring delivery, installation and integration and contracts requiring longer
delivery periods (long-term contracts) is recognized based on completed
milestones or deliverables. Long-term contracts typically run from 18 to 24
months. The Company evaluates profitability on long-term contracts on an ongoing
basis and recognizes losses when identified. Historically, no losses have been
incurred on long-term contracts and no losses are anticipated on contracts in
progress at January 31, 1999.
 
    COST OF SALES.  Information regarding cost of sales related to product sales
and service sales are not disaggregated as such information is not readily
available from the Company's management information system.
 
    PROPERTY AND EQUIPMENT.  Property and equipment are stated at cost.
Depreciation and amortization are computed using the straight-line method based
on the estimated useful lives of the assets or the lease term if shorter.
Building and improvements are depreciated over 40 years. Machinery, equipment,
and furniture are depreciated over three to five years.
 
    INTANGIBLE ASSETS.  Cost in excess of net assets of acquired business
("goodwill") is amortized on a straight line basis over 25 years. The Company
evaluates the realizability of goodwill periodically by comparing the carrying
value to the undiscounted future cash flows of the related assets. Purchased
technology, is included in other assets and amortized over five years. Effective
February 1, 1996, impairments, if any, are recognized in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of," if
applicable.
 
    RESEARCH AND DEVELOPMENT.  Expenditures for research and development are
expensed as incurred, except for certain costs incurred in developing computer
software to be sold, which have been capitalized in accordance with the
provisions of SFAS No. 86, "Accounting for the Costs of Computer Software to Be
Sold, Leased or Otherwise Marketed." Such costs are capitalized once
technological feasibility of the product has been established based upon
completion of a detailed program design. Software costs capitalized amounted to
$522,000, $517,000 and $630,000 for the years ended

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
January 31, 1999, 1998 and 1997, respectively. Capitalized software is included
in other assets and is being amortized to Research and Development expenses on a
straight-line basis over the lesser of three years or the estimated economic
lives of the respective products, beginning when the products are offered for
sale. To date, the estimated useful lives of the products have always exceeded
three years. The Company evaluates the realizability of capitalized software on
an ongoing basis relying on a number of factors including operating results,
business plans, market trends and product development cycles.
 
    TRANSLATION OF FOREIGN CURRENCIES.  The Company denominates substantially
all of its transactions in U.S. currency, except for transactions by its foreign
subsidiary. The assets and liabilities of the Company's foreign subsidiary are
denominated in the country's local currency and translated at the year-end rate
of exchange. The related income statement items are translated at the average
rate of exchange for the year. The resulting translation adjustments are
excluded from income and reflected as a separate component of stockholders'
equity. Realized and unrealized exchange gains or losses arising from
transaction adjustments are reflected in operations and are not material.
 
    INCOME TAXES.  The Company accounts for income taxes using an asset and
liability approach for financial accounting and reporting purposes.
 
    NET INCOME PER SHARE.  The following table sets forth the computation of
basic and diluted earnings per shares ("EPS").

    CASH AND CASH EQUIVALENTS.  The Company considers all highly liquid debt
instruments purchased with an original maturity of three months or less to be
cash equivalents. These instruments are recorded at their carrying values which
approximate fair values because of their short maturity.
 
    USING ESTIMATES.  In preparing financial statements in conformity with
generally accepted accounting principles, management is required to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the date
of the financial statements, as well as revenue and expenses during the
reporting period. Actual results could differ from those estimates.

NOTE H--STOCK OPTION PLANS
 
    The Company has two stock option plans, the 1991 Option Plan ("1991 Option
Plan") and the 1991 Directors Option Plan ("1991 Directors Option Plan")
accounted for under APB Opinion 25, "Accounting for Stock Issued to Employees,"
and related interpretations. The 1991 Option Plan provides for the granting of
incentive and non-statutory options to employees. The 1991 Directors Option Plan
provides for the granting of nonqualifed stock options to directors of the
Company who are not employees of the Company. The options, which have terms of
five or ten years when issued, typically vest over three years. The exercise
price of each option equals the market price of the Company's stock on the date
of grant or, in the case of those holding more than 10% of the

NOTE H--STOCK OPTION PLANS (CONTINUED)
Company's outstanding common stock, 110% of the market price. Accordingly, no
compensation cost has been recognized for grants from either plan. A total of
1,129,327 shares of the Company's common stock have been reserved for issuance
under the 1991 Option Plan, of which 255,182 shares are available for grant at
January 31, 1999. The 1991 Directors Option Plan has 75,000 common shares
reserved, of which 6,000 shares are available for grant at January 31, 1999.
 
    Had compensation costs for the plans been determined based on the fair value
of the options at the grant dates consistent with the method of SFAS No. 123,
"Accounting for Stock-Based Compensation," the Company's net income and income
per share would have been reduced to the pro forma amounts indicated below. Pro
forma results for 1999, 1998 and 1997 may not be indicative of pro forma results
in future periods because the pro forma amounts do not include pro forma
compensation cost for options granted prior to February 1, 1995.

                          AGREEMENT AND PLAN OF MERGER
 
    THIS AGREEMENT (the "Agreement") is dated as of March 23, 1999, by and among
MTS SYSTEMS CORPORATION, a Minnesota corporation ("Parent"), BADGER MERGER
CORP., a Delaware corporation and wholly-owned subsidiary of Parent ("Merger
Subsidiary"), and DSP TECHNOLOGY INC., a Delaware corporation (the "Company").
 
    WHEREAS, the respective Boards of Directors of Parent, Merger Subsidiary,
and the Company have each approved the merger of Merger Subsidiary with and into
the Company (the "Merger") upon the terms and subject to the conditions set
forth herein; and
 
    WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"); and
 
    WHEREAS, for accounting purposes, it is intended that the Merger shall be
accounted for as a "pooling of interests" transaction within the meaning of
Accounting Principles Board Opinion No. 16 and the rules and regulations of the
Securities and Exchange Commission (the "SEC"); and
 
    WHEREAS, the parties hereto desire to make certain representations,
warranties, and agreements in connection with the Merger and also to prescribe
various conditions to the Merger;
 
    NOW, THEREFORE, in consideration of the foregoing premises and the mutual
representations, warranties, covenants, and agreements contained herein, the
parties hereto agree as follows:
 
                   ARTICLE 1 THE MERGER; CONVERSION OF SHARES
 
    1.1  THE MERGER.  Subject to the terms and conditions of this Agreement, at
the Effective Time (as defined in Section 1.2 hereof), Merger Subsidiary shall
be merged with and into the Company in accordance with the provisions of the
Delaware General Corporation Law (the "DGCL"), whereupon the separate corporate
existence of Merger Subsidiary shall cease. The Company shall continue as the
surviving corporation (the "Surviving Corporation") in the Merger. From and
after the Effective Time, the Surviving Corporation shall possess all the
rights, privileges, immunities, powers, and franchises and be subject to all the
restrictions, disabilities, and duties of the Company and Merger Subsidiary, all
as more fully described in the DGCL.
 
    1.2  EFFECTIVE TIME.  As soon as practicable after each of the conditions
set forth in Article 6 has been satisfied or waived on the Closing Date (as
defined in Section 2.1), the Company will file, or cause to be filed, with the
Secretary of State of the State of Delaware a Certificate of Merger for the
Merger, which Certificate shall be in the form required by and executed in
accordance with the applicable provisions of the DGCL. The Merger shall become
effective at the time such filing is made or, if agreed to by Parent and the
Company, such later time or date set forth in the Certificate of Merger (the
"Effective Time").
 
    1.3  CONVERSION OF SHARES AND OPTIONS.  At the Effective Time, by virtue of
the Merger and without any action on the part of the Company, Parent, Merger
Subsidiary or any holder of any share of capital stock, or holder of options to
purchase capital stock, of the Company or Merger Subsidiary:
 
        (a) The holders of shares of common stock of the Company, $.001 par
    value per share ("Company Common Stock") and holders of option(s) to
    purchase Company Common Stock ("Company Option(s)") will receive an
    aggregate of 2,077,000 shares of the common stock of Parent ("Parent Common
    Stock"), $.25 par value per share (the "Merger Consideration"), such that
    each share of Company Common Stock outstanding immediately prior to the
    Effective Time and each Option Share (as defined in Section 1.3(b)) will
    represent only the right to receive a fraction of a share of Parent Common
    Stock equal to the Merger Consideration divided by the
 
                                      A-5
<PAGE>
    sum of (i) the total number of shares of Company Common Stock outstanding
    immediately prior to the Effective Time and (ii) the total number of Option
    Shares represented by the Company Options outstanding immediately prior to
    the Effective Time (the "Per Share Merger Consideration").
 
        (b) Each Company Option outstanding immediately prior to the Effective
    Time shall represent the number of Option Shares ("Option Shares")
    determined by (i) dividing the Option Value by the Final Company Value and
    (ii) multiplying that result by the number of shares subject to each option.
    The "Option Value" shall mean the Final Company Value less the option
    exercise price, provided, that with respect to any portion of a Company
    Option which is not vested immediately prior to the Effective Time, the
    "Option Value" shall mean (i) the fair value of the unvested portion of the
    Company Option (as determined pursuant to an appropriate discounting method
    mutually agreed to by the parties), less (ii) the option exercise price for
    such unvested portion of the option. The "Final Company Value" shall mean
    the value obtained by adding (x) the Merger Consideration multiplied by the
    Final Parent Price and (y) the aggregate exercise price of the Company
    Options outstanding immediately prior to the Effective Time, and dividing
    the sum of (x) and (y) by the sum of the aggregate number of shares of
    Company Common Stock outstanding immediately prior to the Effective Time and
    the aggregate number of shares of Company Common Stock subject to Company
    Options outstanding immediately prior to the Effective Time. The "Final
    Parent Price" shall mean the closing sale price of a share of Parent Common
    Stock as reported by the Nasdaq National Market on the trading day
    immediately prior to the Effective Time.
 
        (c) Each share of Company Common Stock issued and outstanding
    immediately prior to the Effective Time that is held in the treasury of the
    Company shall be canceled in accordance with applicable laws without payment
    of any consideration therefor and without any conversion thereof.
 
        (d) Each share of any other class of capital stock of the Company (other
    than Company Common Stock) shall be canceled without payment of any
    consideration therefor and without any conversion thereof.
 
        (e) Each share of common stock of Merger Subsidiary, par value $.01 per
    share ("Merger Subsidiary Common Stock"), issued and outstanding immediately
    prior to the Effective Time shall be converted into one share of the common
    stock of the Surviving Corporation, par value $.001 per share ("Surviving
    Corporation Common Stock").
 
    1.4  NO APPRAISAL RIGHTS.  The parties acknowledge that, pursuant to Section
262(b)(1) of the DGCL, no holders of Company Common Stock shall have appraisal
rights in connection with the Merger.
 
    1.5  EXCHANGE OF COMPANY COMMON STOCK.
 
        (a) At or prior to the Effective Time, Parent shall cause the Company's
    stock transfer agent, or such other agent as is mutually agreed to by the
    parties, to act as exchange agent (the "Exchange Agent") hereunder. As
    promptly as practicable after the Effective Time, Parent shall cause the
    Exchange Agent to mail (i) to each holder of record (other than Parent,
    Merger Subsidiary, the Company, or any wholly owned subsidiary of Parent or
    the Company) of a certificate or certificates that immediately prior to the
    Effective Time represented outstanding shares of Company Common Stock
    ("Company Certificates") a form letter of transmittal (which shall specify
    that delivery shall be effective, and risk of loss and title to the Company
    Certificate(s) shall pass, only upon delivery of the Company Certificate(s)
    to the Exchange Agent) and instructions for such holder's use in effecting
    the surrender of the Company Certificates in exchange for certificates
    representing shares of Parent Common Stock and cash in lieu of any
    fractional shares, and (ii) to each holder of Company Option(s) a form
    letter of transmittal and
 
                                      A-6
<PAGE>
    instructions for such holder's use in effecting the receipt of certificates
    representing shares of Parent Common Stock and cash in lieu of any
    fractional shares in exchange for such Company Option(s).
 
        (b) As soon as practicable after the Effective Time, the Exchange Agent
    shall distribute to holders of shares of Company Common Stock, upon
    surrender to the Exchange Agent of one or more Company Certificates for
    cancellation, together with a duly-executed letter of transmittal, (i) one
    or more certificates representing the number of whole shares of Parent
    Common Stock into which the shares represented by the Company Certificate(s)
    shall have been converted pursuant to Section 1.3(a), (ii) a bank check in
    the amount of cash into which the shares represented by the Company
    Certificate(s) shall have been converted pursuant to Section 1.5(f)
    (relating to fractional shares), and (iii) any dividends or other
    distributions to which such holder is entitled pursuant to Section 1.5(c),
    and the Company Certificate(s) so surrendered shall be canceled. In the
    event of a transfer of ownership of Company Common Stock that is not
    registered in the transfer records of the Company, it shall be a condition
    to the issuance of shares of Parent Common Stock that the Company
    Certificate(s) so surrendered shall be properly endorsed or be otherwise in
    proper form for transfer and that such transferee shall (i) pay to the
    Exchange Agent any transfer or other taxes required or (ii) establish to the
    satisfaction of the Exchange Agent that such tax has been paid or is not
    payable. As soon as practicable after the Effective Time, the Exchange Agent
    shall distribute to holders of Company Options, upon surrender to the
    Exchange Agent of a duly-executed letter of transmittal, (i) one or more
    certificates representing the number of whole shares of Parent Common Stock
    into which the Option Shares represented by the Company Options shall have
    been converted pursuant to Section 1.3(a), (ii) a bank check in the amount
    of cash into which the Option Shares represented by the Company Options
    shall have been converted pursuant to Section 1.5(f) (relating to fractional
    shares), and (iii) any dividends or other distributions to which such holder
    is entitled pursuant to Section 1.5(c).
 
        (c) Holders of Company Common Stock or Company Options will be entitled
    to any dividends or other distributions pertaining to the Parent Common
    Stock received in exchange therefor that become payable to persons who are
    holders of record of Parent Common Stock as of a record date that follows
    the Effective Time, but only (i) for holders of Company Common Stock, after
    they have surrendered their Company Certificates for exchange and (ii) for
    holders of Company Options, after they have submitted a duly-executed letter
    of transmittal. Subject to the effect, if any, of applicable law, the
    Exchange Agent shall receive, hold, and remit any such dividends or other
    distributions to each such record holder entitled thereto, without interest,
    at the time that such Company Certificates are surrendered to the Exchange
    Agent for exchange. Holders of Company Common Stock or Company Options will
    not be entitled, however, to dividends or other distributions that become
    payable before or after the Effective Time to persons who were holders of
    record of Parent Common Stock as of a record date that is prior to the
    Effective Time.
 
        (d) All certificates evidencing shares of Parent Common Stock that are
    issued (i) upon the surrender for exchange of Company Certificates or (ii)
    in exchange for Company Options in accordance with the terms hereof,
    together with any cash paid for fractional shares pursuant to Section 1.5(f)
    hereof, shall be deemed to have been issued in full satisfaction of all
    rights pertaining to the shares of Company Common Stock represented by the
    surrendered Company Certificates or Option Shares represented by the Company
    Options, respectively.
 
        (e) After the Effective Time, there shall be no further registration of
    transfers on the stock transfer books of the Surviving Corporation of the
    shares of Company Common Stock that were outstanding immediately prior to
    the Effective Time. If, after the Effective Time, Company Certificates
    representing such shares are presented to the Surviving Corporation, they
    shall be canceled and exchanged as provided in this Article 1. As of the
    Effective Time, the holders of Company Certificates representing shares of
    Company Common Stock shall cease to have any
 
                                      A-7
<PAGE>
    rights as stockholders of the Company, except such rights, if any, as they
    may have pursuant to the DGCL or this Agreement. Except as provided above,
    until such Company Certificates are surrendered for exchange, each such
    Company Certificate shall, after the Effective Time, represent for all
    purposes only the right to receive a certificate or certificates evidencing
    the number of whole shares of Parent Common Stock into which the shares of
    Company Common Stock shall have been converted pursuant to the Merger as
    provided in Section 1.3(a) hereof, the right to receive the cash value of
    any fraction of a share of Parent Common Stock as provided in Section 1.5(f)
    hereof and the right to receive any dividends or distributions as provided
    in Section 1.5(c). As of the Effective Time, the holders of Company Options
    shall cease to have any rights as optionholders of the Company, except such
    rights, if any, as they may have pursuant to this Agreement.
 
        (f) No fractional shares of Parent Common Stock and no certificates or
    scrip therefor, or other evidence of ownership thereof, shall be issued in
    connection with the Merger, no dividend or other distribution of Parent
    shall relate to any fractional share, and such fractional share interests
    shall not entitle the owner thereof to vote or to any rights of a
    shareholder of Parent. All fractional shares of Parent Common Stock to which
    a holder of Company Common Stock or Company Option(s) immediately prior to
    the Effective Time would otherwise be entitled, at the Effective Time, shall
    be aggregated if and to the extent multiple Company Certificates of such
    holder are submitted together to the Exchange Agent and/or multiple Company
    Options are held by such holder. If a fractional share results from such
    aggregation, then (in lieu of such fractional share) the Exchange Agent
    shall pay to each holder of shares of Company Common Stock or Company
    Options who otherwise would be entitled to receive such fractional share of
    Parent Common Stock an amount of cash (without interest) determined by
    multiplying (i) the closing sale price of a share of Parent Common Stock as
    reported by the Nasdaq National Market on the Closing Date by (ii) the
    fractional share of Parent Common Stock to which such holder would otherwise
    be entitled. Parent will make available to the Exchange Agent any cash
    necessary for this purpose.
 
        (g) In the event any Company Certificates shall have been lost, stolen,
    or destroyed, the Exchange Agent shall issue in respect of such lost,
    stolen, or destroyed Company Certificates, upon the making of an affidavit
    of that fact by the holder thereof, such shares of Parent Common Stock, cash
    for fractional shares, if any, and dividends or other distributions, if any,
    as may be required pursuant to this Article 1; provided, however, that
    Parent may, in its discretion and as a condition precedent to the issuance
    thereof, require the owner of such lost, stolen, or destroyed Company
    Certificate to deliver a bond in such sum as Parent may reasonably direct as
    indemnity against any claim that may be made against Parent or the Exchange
    Agent with respect to such Company Certificate alleged to have been lost,
    stolen, or destroyed.
 
    1.6  EXCHANGE OF MERGER SUBSIDIARY COMMON STOCK.  From and after the
Effective Time, each outstanding certificate previously representing shares of
Merger Subsidiary Common Stock shall be deemed for all purposes to evidence
ownership of and to represent the number of shares of Surviving Corporation
Common Stock into which such shares of Merger Subsidiary Common Stock shall have
been converted, such conversion to be on the basis of one share of Surviving
Corporation Common Stock for each share of Merger Subsidiary Common Stock.
Promptly after the Effective Time, the Surviving Corporation shall issue to
Parent a stock certificate or certificates representing such shares of Surviving
Corporation Common Stock in exchange for the certificate or certificates that
formerly represented shares of Merger Subsidiary Common Stock, which shall be
canceled.
 
    1.7  CERTIFICATE OF INCORPORATION OF THE SURVIVING CORPORATION.  The
Certificate of Incorporation of the Company, as in effect immediately prior to
the Effective Time, shall be amended as set forth on EXHIBIT A attached hereto,
and shall, as amended, subject to Section
 
                                      A-8
<PAGE>
5.21, be the Certificate of Incorporation of the Surviving Corporation until
thereafter amended in accordance with applicable law.
 
    1.8  BYLAWS OF THE SURVIVING CORPORATION.  The Bylaws of the Company, as in
effect immediately prior to the Effective Time, shall, subject to Section 5.21,
be the Bylaws of the Surviving Corporation until thereafter amended in
accordance with applicable law.
 
    1.9  DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION.  The directors and
officers of Merger Subsidiary immediately prior to the Effective Time shall be
the directors and officers, respectively, of the Surviving Corporation until
their respective successors shall be duly elected and qualified.
 
                               ARTICLE 2 CLOSING
 
    2.1  TIME AND PLACE.  Subject to the satisfaction or waiver of the
provisions of Article 6, the closing of the Merger (the "Closing") shall take
place at 1:00 p.m., local time, on the date that the Required Company
Stockholder Vote (as defined in Section 3.2) is obtained, or as soon thereafter
as, and in any event no later than the second business day after, all conditions
to Closing have been satisfied or waived, or on such other date and/or at such
other time as Parent and the Company may mutually agree. The date on which the
Closing actually occurs is herein referred to as the "Closing Date." The Closing
shall take place at the corporate headquarters offices of Parent, or at such
other place or in such other manner (e.g., by facsimile exchange of signature
pages with originals to promptly follow by overnight delivery) as the parties
hereto may agree.
 
    2.2  FILINGS AT THE CLOSING.  At the Closing, subject to the provisions of
Article 6, Parent, Merger Subsidiary, and the Company shall cause the
Certificate of Merger to be filed in accordance with the provisions of Section
252 of the DGCL, and take any and all other lawful actions and do any and all
other lawful things necessary to cause the Merger to become effective.
 
            ARTICLE 3 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    Except: (i) as set forth in a document of even date herewith and
concurrently delivered herewith (the "Company Disclosure Schedule") or (ii) as
specifically described through express disclosure of current, specific facts set
forth in the Company's Annual Report on Form 10-K for the fiscal year ended
January 31, 1998 or in any other filing by the Company with the SEC (as defined
in Section 3.4) filed after the date of filing such Form 10-K and prior to the
date hereof (for purposes of clauses (i) and (ii) above, disclosures in the
Company Disclosure Schedule and such Company SEC filings shall be deemed to
qualify or limit only those particular representations and warranties set forth
in this Article 3 to which the relevancy of such disclosures is readily
apparent), the Company hereby makes the following representations and warranties
to Parent and Merger Subsidiary:
 
    3.1  ORGANIZATION.  The Company and each subsidiary (referred to herein with
respect to the Company or Parent, as applicable, as a "Subsidiary") of the
Company is an entity duly organized, validly existing, and in good standing
(where such concept is recognized) under the laws of its respective jurisdiction
of organization and has all requisite corporate power and authority to own,
lease, and operate its properties and to carry on its business as now being
conducted, except where the failure to be so organized, existing or in good
standing or to have such corporate power and authority would not, individually
or in the aggregate, have a Company Material Adverse Effect (as defined below).
The Company and each Subsidiary is duly qualified and in good standing to do
business in each jurisdiction in which the property owned, leased, or operated
by it or the nature of the business conducted by it makes such qualification
necessary, except where the failure to be so qualified or in good standing would
not have a Company Material Adverse Effect. "Company Material Adverse Effect"
means an effect that is, or at the time of such effect it is probable that the
effect will be, materially adverse: (i) to the business, results of operation,
or financial condition of the Company and its Subsidiaries,
 
                                      A-9
<PAGE>
considered as a whole; (ii) to the ability of the Surviving Corporation to
conduct such business, as presently conducted, following the Effective Time or
the ability of Parent to derive the benefits of owning all of the stock of the
Surviving Corporation; or (iii) to the Company's ability to perform any of its
material obligations under this Agreement or to consummate the Merger; PROVIDED,
HOWEVER, that none of the following shall be deemed to have a Material Adverse
Effect on the Company: (A) a change in the market price or trading volume of the
Company Common Stock, (B) a failure by the Company to meet any published
securities analyst estimates of revenue or earnings for any period ending or for
which earnings are released on or after the date of this Agreement and prior to
the Closing, (C) an event, violation, inaccuracy, circumstance or other matter
that results from conditions affecting the U.S. or world economy, (D) an event,
violation, inaccuracy, circumstance or other matter that results from conditions
affecting the powertrain testing or instrumentation industry generally, (E) an
event, violation, inaccuracy, circumstance or other matter that results
primarily from the announcement or the pendency of the Merger or the
transactions contemplated by this Agreement or (F) an event violation,
inaccuracy, circumstance or other matter that results from the taking of any
action required or permitted by this Agreement. The jurisdictions in which the
Company and each Subsidiary are incorporated are listed in the Company
Disclosure Schedule. The Company has heretofore delivered or made available to
Parent or its advisers complete and accurate copies of the Certificate of
Incorporation and Bylaws of the Company, as currently in effect, and of the
organizational documents and agreements defining the rights of the Company or
any Subsidiary with respect to any material joint ventures, partnerships or
other business in which the Company owns less than substantially all of the
outstanding equity interest. As of the date hereof, neither the Company nor any
Subsidiary, directly or indirectly, owns or controls or has any material equity,
partnership, or other similar ownership interest in any corporation,
partnership, joint venture, or other business association or entity that is
material to the Company and its Subsidiaries, considered as a whole.
 
    3.2  AUTHORIZATION.  The Company has all necessary corporate power and
authority to execute and deliver this Agreement and, subject to obtaining the
necessary approval of its stockholders, to consummate the transactions
contemplated hereby. The execution and delivery by the Company of this Agreement
and the other agreements contemplated hereby to which the Company is a party,
and the consummation by the Company of the transactions contemplated hereby and
thereby, have been duly and validly authorized and approved by the Company's
Board of Directors, no other corporate proceedings on the part of the Company,
other than a meeting of the Company's stockholders (the "Company Stockholders'
Meeting"), are necessary to authorize this Agreement, and, subject to obtaining
the approval and adoption of this Agreement and approval of the Merger by a
majority of the shares of the Company Common Stock outstanding as of the record
date of the Company Stockholders' Meeting (the "Required Company Stockholder
Vote"), no other corporate action on the part of the Company is necessary to
consummate the transactions contemplated hereby. The Merger has been declared
advisable by the Board of Directors of the Company. This Agreement has been duly
and validly executed and delivered by the Company and, assuming due execution
and delivery by the other parties hereto, constitutes the valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms, subject to laws of general application relating to bankruptcy,
insolvency, and the relief of debtors and rules of law governing specific
performance, injunctive relief, or other equitable remedies.
 
    3.3  CAPITALIZATION.  As of the close of business on February 26, 1999, the
authorized capital stock of the Company consisted of (i) 25,000,000 shares of
Company Common Stock, $.001 par value per share, of which 2,242,179 were issued
and outstanding and 90,200 shares were held in the Company's treasury, and (ii)
2,500,000 shares of Company Preferred Stock, none of which were issued or
outstanding. All issued and outstanding shares of capital stock of each
Subsidiary are owned, beneficially and of record, by the Company, free and clear
of any mortgage, pledge, security interest, encumbrance, lien or other charge of
any kind ("Lien") that would materially affect the Company's interest in such

encumbrance by the Company or any Subsidiary of any shares of its capital stock,
or (c) related to the voting or control of such capital stock. The Company

outstanding as of February 26, 1999, including the name of the holder, the date
of grant, acquisition price, number of shares, exercisability schedule, and, in
the case of options, the type of option under the Code. No consent of holders or
participants under the Stock Option Plans is required to carry out the

Company under the Stock Option Plans to allow for the treatment of Company
Options as is provided in Section 1.3, have been, or prior to the Closing will
be, validly taken by the Company.
 
    3.4  REPORTS AND FINANCIAL STATEMENTS.  The Company has filed all forms,
reports, registration statements, and other documents required to be filed by it
with the SEC since February 1, 1995 (such forms, reports, registration

accordance with U.S. generally accepted accounting principles except: (a)
liabilities or obligations that will be accrued or reserved against in the

approvals or violations, breaches, defaults, or other occurrences that could not
reasonably be expected to prevent or delay consummation of any of the
transactions contemplated hereby in any material respect, or otherwise prevent
the Company from performing its obligations under this Agreement in any material
respect, and would not have a Company Material Adverse Effect.
 
    3.7  COMPLIANCE WITH LAWS.  Neither the Company nor any Subsidiary is in
default or violation in any material respect of any applicable federal, state,
local, or foreign laws, ordinances, regulations, published interpretations,

    Company or any Subsidiary, other than Merger-Related Proceedings and except
    for such claims, actions, suits, proceedings, governmental investigations or
    governmental reviews that would not have a Company Material Adverse Effect.
 
    3.9  ABSENCE OF MATERIAL ADVERSE CHANGES.  Between January 31, 1999 and the
date hereof, there has not been any (a) Company Material Adverse Effect; (b)
damage, destruction, or loss, not covered by insurance, that would have a

purposes, except as required by a change in applicable law or generally accepted

action described or referenced in this Section 3.9.
 
    3.10  OFFICERS, DIRECTORS AND EMPLOYEES.  Prior to the date hereof, the
Company has provided to Parent a list that completely and accurately sets forth,
as of the date hereof, the name and current annual salary rate of each current
officer of the Company whose total remuneration for the last fiscal year was, or
for the current fiscal year has been set at, in excess of $100,000, together

extensions to file (which extensions have not expired without filing), all
state, local, United States, foreign, or other tax reports and returns required

                                      A-13
<PAGE>
Company Audited Balance Sheet will be adequate to cover all taxes payable by the
Company and its Subsidiaries for all taxable periods and portions thereof ending
on or before the dates thereof. To the Company's knowledge, no tax audits are
pending against and no claims for taxes have been received in writing by the
Company or any of its Subsidiaries, other than audits and claims that would not
have a Company Material Adverse Effect. Neither the Company nor any Subsidiary
has, with regard to any assets or property held, acquired or to be acquired by
any of them, filed a consent to the application of Section 341(f)(2) of the
Code. Neither the Company nor any of its Subsidiaries has taken or agreed to
take any action (other than actions contemplated by this Agreement) that would
prevent the Merger from constituting a reorganization qualifying under Section
368(a) of the Code. The Company is not aware of any agreement, plan or other
circumstance that would prevent the Merger from so qualifying under Section
368(a) of the Code.
 
For the purposes of this Agreement, "tax" shall mean and include taxes, duties,
withholdings, assessments, and charges assessed or imposed by any governmental

liability for taxes arising as a result of being (or ceasing to be) a member of
any affiliated, consolidated, combined, or unitary group as well as any
liability for taxes under any tax allocation, tax sharing, tax indemnity, or
similar agreement.
 
    3.12  CONTRACTS.  The Company Disclosure Schedule lists, and the Company has
heretofore furnished to Parent complete and accurate copies of (or, if oral, the
Company Disclosure Schedule states all material provisions of), every
employment, consulting, severance or change of control agreement or arrangement
for the benefit of any director, officer, employee, other person or stockholder
of the Company or any Subsidiary or any affiliate thereof in effect as of the
date of this Agreement to which the Company or any Subsidiary is a party or by
which the Company or any Subsidiary or any of their properties or assets is
bound. Neither the Company nor any Subsidiary is in material violation of or in
default under any contract, plan, agreement, understanding, arrangement or
obligation that is material to the Company and its Subsidiaries, considered as a
whole, except for such violations or defaults that would not have a Company
Material Adverse Effect. As of the date of this Agreement, neither the Company
nor any Subsidiary is a party to any contract, plan, agreement, understanding,
arrangement or obligation (i) which materially restricts the Company's, or after
the Merger would materially restrict the Surviving Corporation's or Parent's,
ability to conduct any material line of business currently conducted by the
Company, (ii) which imposes on the Company or any Subsidiary material
obligations, the non-performance of which would have a Company Material Adverse
Effect, that are not reflected in the Company's financial statements included
within the Company's SEC Filings, or (iii) that would be required to be filed
with the SEC in a filing to which paragraph (b)(10) of Item 601 of Regulation
S-K of the Rules and Regulations of the SEC is applicable, which has not been so
filed.
 
    3.13  INTELLECTUAL PROPERTY RIGHTS.  For purposes of this Section,
"Intellectual Property" shall mean patents, mask works, trademarks, trade names,
service marks, copyrights, know-how, trade secrets and other proprietary
information, the loss, impairment or misappropriation of which, either
individually or in the aggregate, would have a Company Material Adverse Effect,
and all applications for or registrations of any of the foregoing. Except as set
forth in the Company Disclosure Schedule, the Company and its Subsidiaries own
or have a valid license to (or otherwise possess legally enforceable rights to
use) the Intellectual Property used in or necessary for the conduct of the
Company's business as conducted prior to the date of this Agreement ("Company
Intellectual Property"), free and clear of any Lien (as defined in Section 3.3,
but excluding licenses) that would have a Company Material Adverse Effect. As of
the date of this Agreement, the Company Disclosure
 
                                      A-14
<PAGE>
Schedule contains a complete and accurate list of (i) all patents, mask works,
trademarks (with a separate listing of registered and unregistered trademarks),
trade names, service marks and registered copyrights in the Company Intellectual
Property, (ii) all applications and registrations therefor, and (iii) all
licenses or other agreements pursuant to which the Company grants any rights
relating to Company Intellectual Property to a third party (other than end-user
licenses). As of the date of this Agreement, the Company Disclosure Schedule
contains a list of all licenses or agreements from a third party to the Company
or any Subsidiary relating to any Intellectual Property that the Company is
licensed or otherwise authorized by such third parties to use, distribute or
otherwise exploit (other than any item of Intellectual Property generally
available on standard terms and conditions). To the knowledge of the Company, no
claim is being asserted and no person is threatening in a writing delivered to
the Company or a Subsidiary to assert a claim, with respect to the use of the
Company Intellectual Property owned by the Company or challenging or questioning
the validity or effectiveness of any license or agreement with respect to any
Company Intellectual Property, except for such claims that would not have a
Company Material Adverse Effect. To the knowledge of the Company, neither the
use by the Company or any Subsidiary of the Company Intellectual Property in the
present conduct of its business nor any product or service of the Company or any
Subsidiary infringes on the valid intellectual property rights of any person in
a manner that would have a Company Material Adverse Effect. Except as would not
have a Company Material Adverse Effect, (i) unless provided otherwise in the
Company Disclosure Schedule, all applications listed in the Company Disclosure
Schedule are still pending in good standing and have not been abandoned, and
(ii) to the knowledge of the Company, the Company Intellectual Property is not
being challenged in any judicial or administrative (excluding any patent-office
or registration) proceeding. To the knowledge of the Company, no person or
entity, nor such person's or entity's business or products has infringed, or
misappropriated any Company Intellectual Property, or currently is infringing,
or misappropriating any Company Intellectual Property, except as would not have
a Company Material Adverse Effect.
 
    3.14  BENEFIT PLANS.
 
        (a) Except as set forth on the Company Disclosure Schedule, neither the
    Company nor any Subsidiary sponsors, maintains, contributes to, or has,
    during the five year period ending on the date of this Agreement, sponsored,
    maintained, or contributed to or been required to contribute to, any
    "employee pension benefit plan" ("Pension Plan"), as such term is defined in
    Section 3(2) of the Employee Retirement Income Security Act of 1974, as
    amended ("ERISA"), including, solely for the purpose of this subsection, a
    plan excluded from coverage by Section 4(b)(5) of ERISA. Each such Pension
    Plan presently maintained by the Company or any Subsidiary is, in all
    material respects, in compliance with applicable provisions of ERISA, the
    Code, and other applicable law and the Company or such Subsidiary has
    performed all of its obligations under such Pension Plan except for such
    obligations that would not have a Company Material Adverse Effect.
 
        (b) Neither the Company nor any Subsidiary sponsors, maintains,
    contributes to, or has, during the five year period ending on the date of
    this Agreement, sponsored, maintained, or contributed to or been required to
    contribute to, any Pension Plan that is subject to Title IV of ERISA.
 
        (c) Except as set forth on the Company Disclosure Schedule, neither the
    Company nor any Subsidiary sponsors, maintains, or contributes to any
    "employee welfare benefit plan" ("Welfare Plan"), as such term is defined in
    Section 3(1) of ERISA, whether insured or otherwise, and any such Welfare
    Plan presently maintained by the Company or any Subsidiary is, in all
    material respects, in compliance with the provisions of ERISA, the Code, and
    all other applicable laws, including, but not limited to, Section 4980B of
    the Code and the regulations thereunder, and Part 6 of Title I of ERISA.
    Neither the Company nor any Subsidiary has established or contributed to any
    "voluntary employees' beneficiary association" within the meaning of Section
    501(c)(9) of the Code.
 
                                      A-15
<PAGE>
        (d) Except as set forth on the Company Disclosure Schedule, neither the
    Company nor any Subsidiary currently maintains or contributes to any
    material oral or written bonus, profit-sharing, compensation (incentive or
    otherwise), commission, stock option, or other stock-based compensation,
    retirement, severance, change of control, vacation, sick or parental leave,
    dependent care, deferred compensation, cafeteria, disability,
    hospitalization, medical, death, retiree, insurance, or other benefit or
    welfare or other similar plan, policy, agreement, trust, fund, or
    arrangement providing for the remuneration or benefit of all or any
    employees, directors or any other person, that is neither a Pension Plan nor
    a Welfare Plan (collectively, the "Compensation Plans").
 
        (e) With respect to the Pension Plans, Welfare Plans or Compensation
    Plans, no event has occurred and, to the knowledge of the Company, there
    exists no condition or set of circumstances, in connection with which the
    Company or any of its Subsidiaries could be subject to any liability under
    the terms of such Plans (other than the payment of benefits thereunder),
    ERISA, the Code or any other applicable law which would have a Company
    Material Adverse Effect.
 
        (f) The Internal Revenue Service has issued favorable determination
    letters with respect to all presently maintained Company and Subsidiary
    Pension Plans that are intended to be qualified under Section 401(a) of the
    Code, or has applied to the Internal Revenue Service for such a
    determination letter prior to the expiration of the requisite period under
    applicable Treasury Regulations or Internal Revenue Service pronouncements
    in which to apply for such a determination and to make any amendments
    necessary to obtain a favorable determination, or has been established under
    a standardized prototype plan for which an Internal Revenue Service opinion
    letter has been obtained by the plan sponsor and is valid as to the adopting
    employer. The Company has made available to Parent the written documents
    setting forth the terms of all Pension Plans, Welfare Plans, Compensation
    Plans, and related agreements, and complete and accurate copies of the three
    most recent annual reports (Form 5500), the most recent favorable
    determination opinion or letters, current summary plan descriptions, and all
    employee handbooks or manuals. The Company has provided to Parent (i) copies
    of all employment agreements with officers of any of the Company, its U.S.
    Subsidiaries or, to the extent reasonably available, the Company's non-U.S.
    Subsidiaries (or copies of forms of agreements setting forth representative
    employment terms and conditions); (ii) copies of all material severance,
    bonus or incentive agreements, programs and policies of any of the Company,
    any U.S. Subsidiary or, to the extent reasonably available, the Company's
    non-U.S. Subsidiaries with or relating to any of its employees; and (iii)
    copies of all plans, programs, agreements and other arrangements of any of
    the Company, any U.S. Subsidiary or, to the extent reasonably available, the
    Company's non-U.S. Subsidiaries with or relating to any of its employees
    which contain change in control provisions. With respect to any items that
    would be described in the immediately preceding sentence but for the fact
    that such copies relate to non-U.S. Subsidiaries and are not reasonably
    available to the Company, the Company (i) shall deliver copies thereof to
    Parent prior to the Effective Time, and (ii) represents and warrants to
    Parent that such items will not, individually or in the aggregate, be
    material to the Company and its Subsidiaries.
 
        (g) The execution by the Company of, and performance by the Company of
    the transactions contemplated in, this Agreement will not (either alone or
    upon the occurrence of any additional or subsequent events) constitute an
    event under any Pension Plan, Welfare Plan, Compensation Plan, or other
    arrangement that will result in any payment (whether of severance pay or
    otherwise), acceleration, forgiveness of indebtedness, vesting,
    distribution, increase in benefits, or obligation to fund benefits. No
    amount that could be received (whether in cash or property or the vesting of
    property) as a result of any of the transactions contemplated by this
    Agreement by any employee, officer, or director of the Company or any of its
    affiliates who is a "disqualified individual" (as such term is defined in
    Prop. Treas. Reg. Section 1.280G-1) under any Pension Plan, Welfare Plan,
 
                                      A-16
<PAGE>
    or Compensation Plan currently in effect would be an "excess parachute
    payment" (as such term is defined in Section 280G(b)(1) of the Code).

its representatives all of its minutes of meetings of and corporate actions or

Board of Directors of the Company since January 1, 1996.

give rise to any claim against any of the parties hereto for a brokerage
commission, finder's fee, or other like payment in connection with the

the Company Disclosure Schedule to those parties identified thereon who have
acted as a finder for the Company or have been retained by the Company as

    3.17  PROXY STATEMENT.  The Proxy Statement/Prospectus (as defined in
Section 5.5 hereof) and any amendments or supplements thereto will comply as to
form in all material respects with all applicable laws, and none of the
information supplied by the Company specifically for inclusion or incorporation
therein or in any amendments or supplements thereto, or in any schedules
required to be filed with the SEC in connection therewith, will, at the date the
Proxy Statement/Prospectus (or any amendment or supplement thereto) is first
mailed to stockholders, or at the time of the Company Stockholders' Meeting,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements

misleading; provided, however, that no representation or warranty is made by the
Company with respect to information supplied by Parent specifically for

affiliates or stockholders included in the Company's filing, or submitted to
Parent and Merger Subsidiary for inclusion in their filing, if any, required to

material respects with all Applicable Laws with respect to Hazardous Substances.
There is no pending or, to the knowledge of the Company, threatened

is and has been no current or past usage or practice of the Company or any of
its U.S. Subsidiaries with respect to any Hazardous Substances which may support
a claim or cause of action against the Company or any of its U.S. Subsidiaries

    ARTICLE 4 REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUBSIDIARY
 
    Except (i) as set forth in a document of even date herewith and concurrently
delivered herewith (the "Parent Disclosure Schedule") or (ii) as specifically
described through express disclosure of current, specific facts set forth in
Parent's Annual Report on Form 10-K for the fiscal year ended September 30, 1998
or in any other filing by Parent with the SEC filed after the date of filing
such Form 10-K and prior to the date hereof (for purposes of clauses (i) and
(ii) above, disclosures in the Parent Disclosure Schedule and such Parent SEC
filings shall be deemed to qualify or limit only those particular
representations and warranties set forth in this Article 4 to which the
relevancy of such disclosures is readily apparent), Parent and Merger Subsidiary
hereby jointly and severally make the following representations and warranties
to the Company:
 
    4.1  ORGANIZATION.  Parent is a corporation duly organized, validly
existing, and in good standing under the laws of the State of Minnesota. Merger
Subsidiary is a corporation duly organized and validly existing under the laws
of the State of Delaware. Each of Parent and Merger Subsidiary has all requisite
corporate power and authority to own, lease, and operate its properties and to
carry on its business as now being conducted, except where the failure to be so
organized, existing or in good standing or to have such corporate power and
authority would not, individually or in the aggregate, have a Parent Material
Adverse Effect (as defined below). Each of Parent and Merger Subsidiary is duly
qualified and in good standing to do business in each jurisdiction in which the
property owned, leased, or operated by it or the nature of the business
conducted by it makes such qualification necessary, except where the failure to
be so qualified or in good standing would not have a Parent Material Adverse
Effect. "Parent Material Adverse Effect" means an effect that is, or at the time
of such effect it is probable that the effect will be, materially adverse (i) to
the business, results of operation, or financial condition of Parent and its
Subsidiaries, considered as a whole, (ii) to Parent's ability to conduct such
business, as presently conducted, following the Effective Time, or (iii) to
Parent's ability to perform any of its material obligations under this Agreement
or to consummate the Merger; provided, however, that none of the following shall
be deemed to have a Material Adverse Effect on Parent: (A) a change in the
market price or trading volume of the Parent Common Stock, (B) a failure by
Parent to meet any published securities analyst estimates of revenue or earnings
for any period ending or for which earnings are released on or after the date of
this Agreement and prior to the Closing, (C) an event, violation, inaccuracy,
circumstance or other matter that results from conditions affecting the U.S. or
world economy, (D) an event, violation, inaccuracy, circumstance or other matter
that results from conditions affecting the powertrain testing or instrumentation
industry generally, (E) an event, violation, inaccuracy, circumstance or other
matter that results primarily from the announcement or the pendency of the
Merger or the transactions contemplated by this Agreement or (F) an event,
violation, inaccuracy, circumstance or other matter that results from the taking
of any
 
                                      A-18
<PAGE>
action required or permitted by this Agreement. Parent has heretofore delivered
or made available to Company or its advisers complete and accurate copies of the
Articles of Incorporation and Bylaws of Parent, as currently in effect, and of
the organizational documents and agreements defining the rights of Parent or any
Subsidiary with respect to any material joint ventures, partnerships or other
business in which Parent owns less than substantially all of the outstanding
equity interest. As of the date hereof, neither Parent nor any Subsidiary,
directly or indirectly, owns or controls or has any material equity,
partnership, or other similar ownership interest in any corporation,
partnership, joint venture, or other business association or entity that is
material to Parent and its Subsidiaries, considered as a whole.
 
    4.2  AUTHORIZATION.  Each of Parent and Merger Subsidiary has all necessary
corporate power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated hereby. The execution and delivery by
Parent and Merger Subsidiary of this Agreement and the other agreements
contemplated hereby to which Parent or Merger Subsidiary is a party, and the
consummation by Parent and Merger Subsidiary of the transactions contemplated
hereby and thereby, have been duly and validly authorized and approved by the
Boards of Directors of Parent and Merger Subsidiary and by Parent as the sole
shareholder of Merger Subsidiary, and no other corporate proceedings on the part
of Parent and Merger Subsidiary, and no vote, consent or approval of Parent's
shareholders, are necessary to authorize this Agreement or to consummate the
transactions contemplated hereby. The Merger has been declared advisable by the
Board of Directors of Merger Subsidiary. This Agreement has been duly and
validly executed and delivered by each of Parent and Merger Subsidiary and,
assuming due execution and delivery by the Company, constitutes the valid and
binding obligation of Parent and Merger Subsidiary, enforceable against each of
them in accordance with its terms, subject to laws of general application
relating to bankruptcy, insolvency, and the relief of debtors and rules of law
governing specific performance, injunctive relief, or other equitable remedies.
 
    4.3  CAPITALIZATION.  As of February 26, 1999, the authorized capital stock
of Parent consisted of 64,000,000 shares of Common Stock with a par value of
$.25 per share, of which there were 18,626,853 shares issued and outstanding.
The authorized capital stock of Merger Subsidiary consists of 2,500 shares of
Merger Subsidiary Common Stock, 1,000 of which are issued and outstanding and
owned by Parent. All issued and outstanding shares of Parent Common Stock and
Merger Subsidiary Common Stock are, and the shares of Parent Common Stock to be
issued and delivered in the Merger pursuant to Article 1 hereof shall be, at the
time of issuance and delivery, validly issued, fully paid, nonassessable, and
free of preemptive rights. The shares of Parent Common Stock to be issued and
delivered in the Merger pursuant to Article 1 hereof shall be registered under
the 1933 Act and duly listed for quotation on the Nasdaq National Market,
subject to official notice of issuance. All issued and outstanding shares of
capital stock of each Subsidiary of Parent are owned, beneficially and of
record, by Parent, free and clear of any Lien that would materially affect
Parent's interest in such shares. As of the close of business on February 25,
1999, except for options to purchase an aggregate total of 2,845,299 shares of
Parent Common Stock that were granted pursuant to Parent's 1990 Stock Option
Plan, 1994 Stock Option Plan or its 1997 Stock Option Plan and that are listed,
together with their respective exercise prices, in the Parent Disclosure
Schedule, there were not any outstanding or authorized subscriptions, options,
warrants, calls, rights, convertible securities, commitments, restrictions,
arrangements, or any other agreements of any character to which Parent or any
Subsidiary was a party that, directly or indirectly, (a) obligated Parent or any
Subsidiary to issue any shares of capital stock or any securities convertible
into, or exercisable or exchangeable for, or evidencing the right to subscribe
for, any shares of capital stock, (b) called for or related to the sale, pledge,
transfer, or other disposition or encumbrance by Parent or any Subsidiary of any
shares of its capital stock, or (c) related to the voting or control of such
capital stock.

the 1933 Act, the 1934 Act, state securities laws, the NASD, the HSR Act, and
Foreign Merger Laws, and (ii) the

<PAGE>
filing and recordation of appropriate merger documents as required by the DGCL,
the execution and delivery by Parent and Merger Subsidiary of this Agreement and
the other agreements contemplated hereby to which Parent and Merger Subsidiary
are parties, and the consummation of the transactions contemplated hereby and
thereby will not: (a) violate any provision of the Certificate or Articles of
Incorporation or Bylaws of Parent or Merger Subsidiary; (b) violate in any
material way any material statute, rule, regulation, order, or decree of any
Governmental Body or any nongovernmental self-regulatory agency by which Parent
or any of its Subsidiaries or any of their respective properties or assets may
be bound; (c) require any filing by Parent or Merger Subsidiary with or permit,
consent, or approval to be obtained by Parent or Merger Subsidiary from any
Governmental Body or any nongovernmental self-regulatory agency; or (d) result
in any violation or breach of, or constitute (with or without due notice or
lapse of time or both) a default under, result in the loss of any material
benefit under, or give rise to any right of termination, cancellation, increased
payments, or acceleration under, or result in the creation of any Lien on any of
the properties or assets of Parent or its Subsidiaries under, any of the terms,
conditions, or provisions of any material note, bond, mortgage, indenture,
license, franchise, permit, agreement, or other instrument or obligation to
which Parent or any of its Subsidiaries is a party, or by which any of them or
any of their respective properties or assets may be bound, except, in the case
of clauses (b), (c) and (d), for any such filings, permits, consents or
approvals or violations, breaches, defaults, or other occurrences that could not
reasonably be expected to prevent or delay consummation of any of the
transaction contemplated hereby in any material respect, or otherwise prevent
Parent from performing its obligations under this Agreement in any material
respect, and would not have a Parent Material Adverse Effect.
 
    4.5  REPORTS AND FINANCIAL STATEMENTS.  Parent has filed all forms, reports,
registration statements, and other documents required to be filed by it with the
SEC since October 1, 1994 (such forms, reports, registration statements and
other documents, together with any amendments thereto, are referred to as the
"Parent SEC Filings"). As of their respective dates, the Parent SEC Filings (i)
complied as to form in all material respects with the applicable requirements of
the 1933 Act and the 1934 Act, as the case may be, and (ii) did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements made therein, in light of
the circumstances under which they were made, not misleading. The audited
financial statements included or incorporated by reference in the Parent SEC
Filings, including but not limited to Parent's audited financial statements at
and for the year ended September 30, 1998 (the "Parent September 30, 1998
Financials"), and the unaudited interim financial statements at and for periods
commencing on or after October 1, 1998 included or incorporated by reference in
the forms, reports, registration statements and other documents filed by Parent
with the SEC (i) were prepared in accordance with generally accepted accounting
principles (except, in the case of unaudited statements, as permitted by Form

involved (except as may be indicated therein or in the notes thereto) subject,
in the case of unaudited interim financial statements, to the absence of notes
and to year-end adjustments, (ii) complied as of their respective dates in all
material respects with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, and (iii) fairly present
in all material respects the consolidated financial position of Parent and its
consolidated Subsidiaries as of the dates thereof and the consolidated income,
cash flows, and changes in shareholders' equity of Parent and its consolidated
Subsidiaries for the periods involved, except as otherwise noted therein and
subject, in the case of unaudited statements, to normal year-end audit
adjustments. The statements of operations included in the audited or unaudited
interim financial statements in the Parent SEC Filings do not contain any items
of special or nonrecurring income or any other income not earned in the ordinary
course of business required to be disclosed separately in accordance with
generally accepted accounting principles, except as expressly specified in the
applicable statement of operations or notes thereto.
 
    4.6  REGISTRATION STATEMENT.  The Registration Statement (as defined in
Section 5.5 hereof) and any amendments or supplements thereto will comply as to
form in all material respects
 
                                      A-20
<PAGE>
with the 1933 Act, and none of the information supplied by Parent specifically
for inclusion or incorporation therein or in any amendments or supplements
thereto, or in any schedules required to be filed with the SEC in connection
therewith, will, at the time the Registration Statement becomes effective, at
the date the Proxy Statement/Prospectus (or any amendment or supplement thereto)
is first mailed to the Company's stockholders or at the time of the Company
Stockholders' Meeting, or at the Effective Time, contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, provided, however,
that no representation or warranty is made by Parent with respect to information
supplied by or on behalf of the Company or any affiliate of the Company
specifically for inclusion in the Registration Statement.
 
    4.7  NO FINDERS.  No act of Parent or Merger Subsidiary has given or will
give rise to any claim against any of the parties hereto for a brokerage

to, a balance sheet prepared in accordance with U.S. generally accepted
accounting principles except: (a) liabilities or obligations that are accrued or
reserved against in the audited consolidated balance of Parent as of September

1998 and (c) liabilities or obligations that would not have a Parent Material

<PAGE>
    4.12  REORGANIZATION.  Neither Parent nor, to the knowledge of Parent, any
of its Subsidiaries has taken or agreed to take any action (other than actions
contemplated by this Agreement) that would prevent the Merger from constituting
a reorganization qualifying under Section 368(a) of the Code. Parent is not
aware of any agreement, plan or other circumstances that would prevent the
Merger from so qualifying under Section 368(a) of the Code.
 
    4.13  MERGER FILINGS.  The information as to Parent and Merger Subsidiary or
any of their affiliates or shareholders included in Parent's filing, or
submitted to the Company for inclusion in its filing, if any, required to be

correct, and complete in all material respects and shall comply in all material
respects with the applicable requirements of the HSR Act, the rules and
regulations issued by the Federal Trade Commission pursuant thereto, and Foreign
Merger Laws.
 
    4.14  ACCOUNTING MATTERS.  To the knowledge of Parent, neither Parent nor
any affiliate (as such term is used in Rule 145 under the Securities Act) of
Parent has taken or agreed to take or plans to take any action that could
prevent Parent from accounting for the Merger as a "pooling of interests" in
accordance with generally accepted accounting principles, Accounting Principles
Board Opinion No. 16 and all published rules, regulations and policies of the
SEC.
 
    4.15  TAXES.  Except for such matters that would not have a Parent Material
Adverse Effect, (i) Parent and each Subsidiary have filed, or have obtained
extensions to file (which extensions have not expired without filing), all
state, local, United States, foreign, or other tax reports and returns required
to be filed by any of them, (ii) Parent and each Subsidiary have duly paid, or

them, filed a consent to the application of Section 341(f)(2) of the Code.

any Subsidiary is a party to any contract, plan, agreement, understanding,
arrangement or obligation (i) which materially restricts Parent's, or after the
Merger would materially restrict the Surviving Corporation's or Parent's,
ability to conduct any material line of business currently conducted by Parent,
(ii) which imposes on Parent or any Subsidiary material obligations , the
non-performance of which would have a Parent Material Adverse Effect, that are
not reflected in Parent's financial statements included within the Parent SEC
Filings, or (iii) that would be required to be filed with the SEC in a filing to
which paragraph (b)(10) of Item 601 of Regulation S-K of the Rules and
Regulations of the SEC is applicable, which has not been so filed.

    Act of 1974, as amended ("ERISA"), including, solely for the purpose of this
    subsection, a plan excluded from coverage by Section 4(b)(5) of ERISA. Each

    all material respects, in compliance with applicable provisions of ERISA,
    the Code, and other applicable law and Parent or such Subsidiary has
    performed all of its obligations under such Pension Plan except for such
    obligations that would not have a Parent Material Adverse Effect.

        (c) Except as set forth on the Parent Disclosure Schedule, neither
    Parent nor any Subsidiary sponsors, maintains, or contributes to any
    "employee welfare benefit plan" ("Welfare Plan"), as such term is defined in

    Plan presently maintained by Parent or any Subsidiary is, in all material
    respects, in compliance with the provisions of ERISA, the Code, and all
    other applicable laws, including, but not limited to, Section 4980B of the
    Code and the regulations thereunder, and Part 6 of Title I of ERISA. Neither
    Parent nor any Subsidiary has established or contributed to any "voluntary
    employees' beneficiary association" within the meaning of Section 501(c)(9)
    of the Code.
 
        (d) Except as set forth on the Parent Disclosure Schedule, neither
    Parent nor any Subsidiary currently maintains or contributes to any material

    otherwise), commission, stock option, or other stock-based compensation,
    retirement, severance, change of control, vacation, sick or parental leave,
    dependent care, deferred compensation, cafeteria, disability,
    hospitalization, medical, death, retiree, insurance, or other benefit or
    welfare or other similar plan, policy, agreement, trust, fund, or
    arrangement providing for the remuneration or benefit of all or any
    employees, directors or any other person, that is neither a Pension Plan nor
    a Welfare Plan (collectively, the "Compensation Plans").
 
        (e) With respect to the Pension Plans, Welfare Plans or Compensation
    Plans, no event has occurred and, to the knowledge of Parent, there exists
    no condition or set of circumstances, in connection with which Parent or any
    of its Subsidiaries could be subject to any liability under the terms of
    such Plans (other than the payment of benefits thereunder), ERISA, the Code
    or any other applicable law which would have a Parent Material Adverse
    Effect.
 
        (f) The Internal Revenue Service has issued favorable determination
    letters with respect to all presently maintained Parent and Subsidiary
    Pension Plans that are intended to be qualified under Section 401(a) of the
    Code, or has applied to the Internal Revenue Service for such a
    determination letter prior to the expiration of the requisite period under
    applicable Treasury Regulations or Internal Revenue Service pronouncements
    in which to apply for such a determination and to make any amendments
    necessary to obtain a favorable determination, or has been established under
    a standardized prototype plan for which an Internal Revenue Service opinion
    letter has been obtained by the plan sponsor and is valid as to the adopting
    employer. Parent has made available to the Company the written documents
    setting forth the terms, or with respect to those plans for which a written
    document does not exist, a summary of the material terms, of all presently
    maintained Pension Plans, Welfare Plans, Compensation Plans, and related
    agreements, and complete and accurate copies of the three most recent annual
    reports (Form 5500), the most recent favorable determination opinion or
    letters, current summary plan descriptions, and all employee handbooks or
    manuals.

    or breached such that the conditions in Section 6.2 will not be satisfied as

        (p) agree, whether in writing or otherwise, to do any of the foregoing.
 
    5.2  CONDUCT OF BUSINESS OF PARENT.  Except as contemplated by this
Agreement or as set forth in Section 5.2 of the Parent Disclosure Schedule,
unless the Company shall otherwise consent in writing (such consent not to be
unreasonably withheld or delayed), during the period from the date of this
Agreement to the Effective Time, Parent and each Subsidiary will (i) conduct its
respective operations, to the extent commercially reasonable, according to its
ordinary and usual course of business and consistent with past practice, and
(ii) use commercially reasonable efforts to preserve substantially intact its
respective business organization, to keep available the services of its
respective officers and employees and to maintain satisfactory relationships
with licensors, licensees, suppliers, contractors, distributors, consultants,
customers, and others having material business relationships with it. Without
limiting the generality of the foregoing, and except as contemplated by this
Agreement, from the date of this Agreement until the Effective Time, Parent will
not do, and will not permit any of its Subsidiaries to do, any of the following
without the prior written consent of the Company (such consent not to be
unreasonably withheld or delayed):

    action by Parent's Board of Directors, amend its Bylaws;
 
        (b) authorize for issuance, issue, sell, pledge, or deliver (whether
    through the issuance or granting of additional options, warrants,
    commitments, subscriptions, rights to purchase, or otherwise) any stock of
    any class or any securities convertible into shares of stock of any class
    (other than, so long as treatment of the Merger as a pooling of interests is
    not reasonably expected by Parent's or the Company's independent accounts to
    be jeopardized, the (i) issuance of shares of Parent Common Stock pursuant
    to the exercise of stock options outstanding on the date of this Agreement
    or granted in accordance with this subsection (b) and (ii) the issuance, in
    the ordinary course of business and consistent with past practice, of stock
    options to purchase, at not less than the fair market value on the date of
    grant, up to the number of shares specified in Section 5.2 of the Parent
    Disclosure Schedule).
 
        (c) combine or reclassify any shares of its capital stock, declare, set
    aside or pay any extraordinary dividend or other distribution (whether in
    cash, stock or property or any combination thereof) in respect of its
    capital stock, or redeem or otherwise acquire any shares of its capital
    stock or its other securities (other than, so long as treatment of the
    Merger as a pooling of interests is not jeopardized, pursuant to Parent's
    previously announced stock repurchase program,
 
                                      A-26
<PAGE>

    existing as of the date of this Agreement) or amend or alter any material
    term of any of its outstanding securities;
 
        (d) acquire or agree to acquire, by merging or consolidating with, or by
    purchasing a substantial portion of the assets of, or by any other manner,
    any business of any corporation, partnership, joint venture, association or

    agree to acquire, or dispose of or agree to dispose of, any assets of any
    person, which, in each case, could reasonably be expected to delay
    materially the consummation of, or increase materially the risk of
    non-consummation of, the transactions contemplated by this Agreement;
 
        (e) except in the ordinary course of business and consistent with past
    practice or pursuant to contractual obligations existing on the date hereof
    or as described in Section 5.2 of the Parent Disclosure Schedule, sell,
    transfer, mortgage, or otherwise dispose of or encumber any assets or
    properties material to the Parent and its Subsidiaries, considered as a
    whole other than any Lien that would not materially adversely affect the
    Parent's and its Subsidiaries' rights with respect to such assets or
    properties;
 
        (f) alter or revise its accounting principles, procedures, methods or
    practices in any material respect, except as required by applicable law or
    regulation or by a change in generally accepted accounting principles and
    concurred with by Parent's independent public accountants;
 
        (g) knowingly take any action that would result in a failure to maintain
    the quotation of Parent Common Stock on the Nasdaq National Market.
 
        (h) knowingly take any action, or knowingly fail to take any action,
    that would render any representation, warranty, covenant or agreement of
    Parent in this Agreement inaccurate or breached such that the conditions in
    Section 6.3 will not be satisfied as of the Closing Date; or
 
        (i) agree, whether in writing or otherwise, to do any of the foregoing.
 
    5.3  NO SOLICITATION.  The Company and its Subsidiaries shall not, and shall
cause their respective officers, directors, employees, representatives, agents,
or affiliates (including, but not limited to any investment banker, attorney or
accountant retained by the Company or any Subsidiary) not to, directly or
indirectly, solicit, knowingly encourage, initiate, or participate in any way in
discussions or negotiations with, or knowingly provide any nonpublic information
to, any corporation, partnership, person, or other entity or group (other than
Parent or any affiliate or agent of Parent) concerning any proposed Alternative
Transaction (as defined below), or otherwise knowingly facilitate any effort or
attempt to propose, make or implement an Alternative Transaction. For purposes
of this Agreement, "Alternative Transaction" shall mean any of the following
involving the Company or any Subsidiary: (i) any tender offer, exchange offer,
merger, consolidation, share exchange, business combination or similar
transaction; (ii) any transaction or series of related transactions pursuant to
which any person or entity (or its shareholders), other than Parent, Merger
Subsidiary or any of their affiliates (a "Third Party") acquires shares (or
securities exercisable for or convertible into shares) representing more than
50% of the outstanding shares of any class of capital stock of the Company or
any Subsidiary; or (iii) any sale, lease, exchange, licensing, transfer or other
disposition pursuant to which a Third Party acquires control of more than 50% of
the assets (including, but not limited to, Intellectual Property assets) of the
Company and its Subsidiaries taken as a whole (determined by reference to the
fair market value of such assets), in a single transaction or series of related
transactions. The Company will immediately terminate all discussions with Third
Parties concerning any proposed Alternative Transaction, and will request that
such Third Parties promptly return any confidential information furnished by the
Company in connection with any proposed Alternative Transaction. The Company
will not waive any provision of any confidentiality, standstill or similar
agreement entered into with any third party regarding any proposed Alternative
Transaction, and prior to the Closing shall enforce all
 
                                      A-27
<PAGE>
such agreements in accordance with their terms. The Company will promptly
communicate to Parent the name of the person or entity submitting, and the terms
and conditions of, any proposal or inquiry that it receives after the date
hereof in respect of any proposed Alternative Transaction or a reasonably
detailed description of any such information requested from it after the date
hereof or of any such negotiations or discussions being sought to be initiated
or continued with the Company after the date hereof in respect of a proposed
Alternative Transaction.
 
The foregoing notwithstanding, this Agreement shall not prohibit the Board of
Directors of the Company from (i) prior to the Required Company Stockholder
Vote, furnishing nonpublic information to or entering into discussions or
negotiations with, any person or entity that makes an unsolicited Superior
Proposal (as defined below), if, and only to the extent that:
 
        (a) the Board of Directors reasonably and in good faith determines that
    failure to take such action would be inconsistent with the fiduciary duties
    of the Board of Directors to its stockholders under applicable law;
 
        (b) prior to first furnishing nonpublic information to, or first
    entering into any substantive discussions and negotiations with, such person
    or entity after the date hereof, the Company (i) provides written notice to
    Parent to the effect that it intends to furnish information to, or enter
    into discussions or negotiations with, a person or entity making a Superior
    Proposal, and naming and identifying the person or entity making the
    Superior Proposal, and (ii) receives from such person or entity an executed
    confidentiality agreement with terms no less favorable to the Company than
    the Confidentiality Agreement (as defined below) entered into with Parent;
    and
 
        (c) the Company provides Parent with all non-public information to be
    provided to such person or entity which Parent has not previously received
    from the Company, and the Company keeps Parent informed, on a daily or more
    regular basis if the context requires or Parent so requests, of the status,
    terms and conditions and all other material information with respect to any
    such discussions or negotiations; and
 
(ii) to the extent applicable, complying with Rule 14e-2 or 14d-9 promulgated
under the 1934 Act with regard to a proposed Alternative Transaction.
 
Nothing in this Section shall (x) permit the Company to terminate this Agreement
(except as specifically provided in Article 7 hereof), or (y) permit the Company
to enter into any agreement providing for an Alternative Transaction (other than
as specifically provided in Article 7 hereof, or the confidentiality agreement
as provided, and in the circumstances and under the conditions set forth, above)
for as long as this Agreement remains in effect.
 
For purposes of this Agreement, a "Superior Proposal" shall mean a proposal for
an Alternative Transaction that the Board of Directors of the Company has
reasonably and in good faith determined (with the advice of its financial
advisors and taking into account all legal, financial and regulatory aspects of
the likelihood of the consummation of such Alternative Transaction, including,
but not limited to, the conditions to consummation and the consequences under
such Alternative Transaction proposal of any material adverse effects or changes
in the Company) to be more favorable to the Company's stockholders than the
transactions contemplated by this Agreement.
 
    5.4  ACCESS AND INFORMATION.
 
        (a) The Company and Parent shall afford each other, and to their
    respective accountants, officers, directors, employees, counsel, and other
    representatives, reasonable access during normal business hours upon
    reasonable prior notice, from the date hereof through the Effective Time, to
    all of its properties, books, contracts, commitments, and records, and,
    during such period, the Company and Parent shall furnish promptly to each
    other all information concerning its and its Subsidiaries' businesses,
    prospects, properties, liabilities, results of operations, financial
    condition,
 
                                      A-28
<PAGE>
    research and development, intellectual property, officers, employees,
    consultants, advisers, distributors, customers, suppliers, and others having
    material dealings with it or any Subsidiary as the other may reasonably
    request, and reasonable opportunity to contact and obtain information from
    such officers, employees, consultants, advisers, distributors, customers,
    suppliers, and others having dealings with it or any Subsidiary as the other
    may reasonably request provided that each party may require the other to
    enter into a supplemental confidentiality agreement with regard to certain
    technical proprietary or competitively sensitive information prior to
    providing such information to the other party. During the period from the
    date hereof to the Effective Time, the parties shall in good faith meet and
    correspond on a regular basis for mutual consultation concerning the conduct
    of their respective businesses and, in connection therewith, Parent and the
    Company shall be entitled, during normal business hours upon reasonable
    prior notice and in a manner that does not unreasonably interfere with the
    other party's business, to have employees or other representatives present
    at the offices of the other party to observe, and be kept informed
    concerning, the other party's operations and business planning.
 
        (b) Parent and the Company shall hold in confidence all such nonpublic
    information as required by and in accordance with the confidentiality
    agreement dated February 3, 1999, between Parent and the Company and any
    supplemental confidentiality agreements entered into between the parties
    prior to the Effective Time (collectively, the "Confidentiality Agreement").
 
    5.5  APPROVAL OF STOCKHOLDERS; PROXY STATEMENT; REGISTRATION STATEMENT.
 
        (a) The Company shall use commercially reasonable efforts to promptly,
    subject to applicable law or SEC or Nasdaq regulations, take all action
    necessary in accordance with the DGCL and the Company's Certificate of
    Incorporation and Bylaws to cause a special meeting of the Company's
    stockholders (the "Company Stockholders Meeting") to be duly called and held
    as soon as reasonably practicable following the date upon which the
    Registration Statement (as defined below) becomes effective for the purpose
    of voting upon the Merger and the adoption and approval of this Agreement
    and at such Meeting to submit this Agreement and the Merger to a vote of the
    stockholders. The stockholder vote or consent required for adoption and
    approval of this Agreement and the approval of the Merger shall be no
    greater than that set forth in the DGCL and the Company's Certificate of
    Incorporation as previously provided to Parent. Accordingly, the Company
    represents and warrants that the affirmative vote of the holders of record
    of a majority of the shares of Company Common Stock outstanding on the
    record date for the Company Stockholders Meeting is all that is necessary to
    obtain stockholder adoption and approval of this Agreement and approval of
    the Merger. The Company shall use commercially reasonable efforts to obtain
    the adoption and approval by the Company's stockholders of this Agreement
    and the approval by the Company's stockholders of the Merger, unless such
    action is inconsistent with the fiduciary duties of the Board of Directors
    to its stockholders imposed by applicable law. In accordance therewith, the
    Company shall, with the cooperation of Parent, prepare and file, as soon as
    reasonably practicable, a proxy statement/ prospectus to be included as part
    of the Registration Statement (such proxy statement/prospectus, together
    with notice of meeting, form of proxy, and any letter or other materials to
    the Company's stockholders included therein are referred to in this
    Agreement as the "Proxy Statement/Prospectus"). Parent shall furnish to the
    Company all information concerning Parent and its subsidiaries, officers,
    directors and shareholders, and shall take such other action and otherwise
    cooperate, as the Company may reasonably request in connection with any such
    action. The Company shall use commercially reasonable efforts to cause the
    definitive Proxy Statement/Prospectus to be mailed to the stockholders of
    the Company as soon as reasonably practicable after the Registration
    Statement shall have become effective, with the date of mailing as mutually
    determined by the Company and Parent. The Proxy Statement/Prospectus shall
    include the recommendation of the Company's Board of Directors in favor of
    the Merger, unless such action is inconsistent with the fiduciary
 
                                      A-29
<PAGE>
    duties of the Board of Directors to its stockholders imposed by applicable
    law. Unless and until this Agreement is validly terminated pursuant to
    Article 7, nothing herein shall limit or eliminate in any way the Company's
    obligation to call, give notice of, convene and hold the Company
    Stockholders Meeting and at such meeting submit this Agreement and the
    Merger to a vote of the Company's stockholders (and not postpone or adjourn
    such meeting or the vote by the Company's stockholders upon this Agreement
    and the Merger to another date without Parent's approval, not to be
    unreasonably withheld if and only to the extent such postponement or
    adjournment is required by law or by SEC or Nasdaq regulation).
 
        (b) Parent shall, with the cooperation of the Company, prepare and file,
    as soon as reasonably practicable following completion of the SEC's review
    and comment on the Proxy Statement/Prospectus, a registration statement
    under the 1933 Act registering the shares of Parent Common Stock to be
    issued in the Merger (the "Registration Statement"), which Registration
    Statement shall include the Proxy Statement/Prospectus. Parent will use
    commercially reasonable efforts to have the Registration Statement declared
    effective by the SEC as promptly thereafter as practicable. Parent shall
    also take any action required to be taken under state blue sky or securities
    laws in connection with the issuance of Parent Common Stock pursuant to the
    Merger. The Company shall furnish to Parent all information concerning the
    Company and its Subsidiaries and the holders of its capital stock, and shall
    take such other action and otherwise cooperate, as Parent may reasonably
    request in connection with any such action.
 
        (c) Parent shall notify the Company promptly (i) of the receipt of the
    comments of the SEC, (ii) of any request by the SEC for amendments or
    supplements to the Registration Statement, (iii) of the time when the
    Registration Statement has become effective or any supplement or amendment
    has been filed, or the issuance of any stop order and (iv) of the suspension
    of the qualification of the Parent Common Stock issuable in connection with
    the Merger for offering or sale in any jurisdiction and shall supply the
    Company with copies of all correspondence with the SEC with respect to the
    Registration Statement.
 
        (d) If at any time prior to the Effective Time, any event or
    circumstance relating to the Company, any Subsidiary, or the Company's
    officers or directors should occur and be discovered by the Company that is
    required to be described in an amendment or supplement to the definitive
    Proxy Statement/Prospectus or the Registration Statement, the Company shall
    promptly inform Parent. If at any time prior to the Effective Time, any
    event or circumstance relating to Parent or any of its subsidiaries or their
    respective officers or directors should occur and be discovered by Parent
    that is required to be described in an amendment or supplement to the
    definitive Proxy Statement/Prospectus or the Registration Statement, Parent
    shall promptly inform the Company. Whenever any event occurs that should be
    described in an amendment of, or supplement to, the definitive Proxy
    Statement/Prospectus or the Registration Statement, the Company or Parent,
    as the case may be, shall, upon learning of such event, promptly notify the
    other and consult and cooperate with the other in connection with the
    preparation of a mutually acceptable amendment or supplement. The parties
    shall promptly file such amendment or supplement with the SEC and mail such
    amendment or supplement as soon as practicable after it is cleared by the
    SEC. No amendment or supplement to the Proxy Statement/Prospectus or the
    Registration Statement will be made by Parent or the Company without the
    approval of the other party (such approval not to be unreasonably withheld
    or delayed).
 
    5.6  CONSENTS.  The Company will, at its cost and expense, use commercially
reasonable efforts to obtain all material approvals and consents of all third
parties necessary on the part of the Company or its Subsidiaries to consummate
the transactions contemplated hereby. Parent agrees to cooperate with the
Company in connection with obtaining such approvals and consents. Parent will,
at its cost and expense, use commercially reasonable efforts to obtain all
material approvals and consents of all third parties necessary on the part of
Parent to consummate the transactions contemplated hereby. The
 
                                      A-30
<PAGE>
Company and Parent agree to cooperate with each other in connection with
obtaining such approvals and consents.
 
    5.7  AFFILIATES' LETTERS.
 
        (a) As soon as practicable after the date of this Agreement, the Company
    shall deliver to Parent a list of names and addresses of those persons, in
    the Company's reasonable judgment after consultation with outside legal
    counsel, who, as of the date hereof, are affiliates within the meaning of
    Rule 145 of the rules and regulations promulgated under the 1933 Act or
    otherwise applicable SEC accounting releases with respect to
    pooling-of-interests accounting treatment (each such person, an "Affiliate")
    of the Company. The Company shall provide Parent such information and
    documents as Parent shall reasonably request for purposes of reviewing such
    list and shall promptly update such list to reflect any changes thereto. As
    soon as practicable after the date of this Agreement, the Company will
    deliver to Parent an affiliate's letter in the form attached hereto as
    EXHIBIT B, executed by each of the Affiliates of the Company identified in
    the foregoing list, and shall use best efforts to deliver or cause to be
    delivered to Parent as soon as practicable after the date hereof such an
    affiliate's letter executed by any persons who, to the knowledge of the
    Company, become Affiliates after the date hereof. Parent shall be entitled
    to place legends as specified in such affiliates' letters on the
    certificates evidencing any of the Parent Common Stock received by such
    Affiliates pursuant to the terms of this Agreement, and to issue appropriate
    stop transfer instructions to the transfer agent for the Parent Common
    Stock, consistent with the terms of such letters.
 
        (b) For so long as resales of shares of Parent Common Stock issued
    pursuant to the Merger are subject to the resale restrictions set forth in
    Rule 145 under the 1933 Act, Parent will use commercially reasonable efforts
    to comply with Rule 144(c)(1) under the 1933 Act.
 
    5.8  EXPENSES.  Whether or not the Merger is consummated, all costs and
expenses incurred in connection with this Agreement, the transactions
contemplated hereby, the Proxy Statement/Prospectus, and the Registration
Statement will be paid by the party incurring such costs and expenses, except
that the Company and Parent will share equally the cost of printing and filing
with the SEC the Proxy Statement/Prospectus and the Registration Statement and
the filing fees required under the HSR Act or any Foreign Merger Laws.
 
    5.9  FURTHER ACTIONS.  Subject to the terms and conditions herein provided
and without being required to waive any conditions herein (whether absolute,
discretionary, or otherwise), each of the parties hereto agrees to use
commercially reasonable efforts to take, or cause to be taken, all action, and
to do, or cause to be done, all things necessary, proper, or advisable to
consummate and make effective the transactions contemplated by this Agreement.
In case at any time after the Effective Time any further action is necessary or
desirable to carry out the purposes of this Agreement, the proper officers and
directors of each party to this Agreement shall take all such necessary action.
 
    5.10  REGULATORY APPROVALS.
 
        (a) The Company and Parent each shall use commercially reasonable
    efforts to take, or cause to be taken, all appropriate action, and do, or
    cause to be done, all things as may be necessary under federal or state
    securities laws or the HSR Act or Foreign Merger Laws (including without
    limitation, furnishing all information required under the HSR Act or Foreign
    Merger Laws and in connection with approvals of or filings with any other
    Governmental Entity) applicable to or necessary for, and will file as soon
    as reasonably practicable and, if appropriate, use commercially reasonable
    efforts to have declared effective or approved all documents and
    notifications with the SEC and other governmental or regulatory bodies
    (including, without limitation, foreign regulatory bodies that administer
    Foreign Merger Laws, and any foreign labor councils or bodies as may be
    required) that they deem necessary or appropriate for the consummation of
    the Merger or any of
 
                                      A-31
<PAGE>
    the other transactions contemplated hereby, and each party shall give the
    other information reasonably requested by such other party pertaining to it
    and its subsidiaries and affiliates to enable such other party to take such
    actions.
 
        (b) Although the parties do not anticipate any legislative,
    administrative or judicial objection to the consummation of the Merger or
    any of the transactions contemplated by this Agreement, each of the Company,
    Parent and Merger Subsidiary shall use commercially reasonable efforts
    vigorously to contest and resist any action, including legislative,
    administrative or judicial action, and to have vacated, lifted, reversed or
    overturned any decree, judgment, injunction or other order (whether
    temporary, preliminary or permanent) (an "Order") that is in effect and that

    the other transactions contemplated by this Agreement, including, without
    limitation, by vigorously pursuing available avenues of administrative and
    judicial appeal. Each of the Company, Parent and Merger Subsidiary shall
    also use commercially reasonable efforts to take any and all actions
    necessary to avoid or eliminate each and every impediment under any
    antitrust law that may be asserted by any governmental antitrust authority
    or any other party so as to enable the parties to close by the date
    specified in Section 7.1(b) the transactions contemplated hereby, including
    without limitation, committing to and/or effecting, by consent decree,
    separate orders, or otherwise, the sale or disposition of such assets or
    businesses as are required to be divested in order to avoid the entry of, or
    to effect the dissolution of, any injunction, temporary restraining order or
    other order in any suit or proceeding, which would otherwise have the effect
    of preventing the consummation by the date specified in Section 7.1(b) of
    all or any material part of the transactions contemplated hereby. The
    Company and Parent shall respond as promptly as practicable to (i) any
    inquiries or requests received from the Federal Trade Commission or the
    Department of Justice or any foreign regulatory bodies that administer
    Foreign Merger Laws for additional information or documentation and (ii) any
    inquiries or requests received from any state attorney general or other
    governmental entity in connection with antitrust or related matters. Each of
    the Company and Parent shall (1) give the other party prompt notice of the
    commencement of any Legal Proceeding by or before any Governmental Entity
    with respect to the Merger or any of the other transactions contemplated by
    this Agreement, (2) keep the other party informed as to the status of any
    such Legal Proceeding, and (3) promptly inform the other party of any
    communication to or from such Government Entity regarding the Merger. The
    Company and Parent will consult with and cooperate with one another and will
    consider in good faith the views of one another, in connection with any
    analysis, appearance, presentation, memorandum, brief, argument, opinion or
    proposal made or submitted in connection with any Legal Proceeding under or
    related to the HSR Act or the Foreign Merger Laws or any other federal or
    state antitrust or fair trade law. In addition, except as may be prohibited
    by any Governmental Entity, in connection with any Legal Proceeding under or
    related to the HSR Act or the Foreign Merger Laws or any other federal or
    state antitrust or fair trade law, or any other similar Legal Proceeding,
    each of the Company and Parent shall permit authorized representatives of
    the other party to be present at each meeting or conference relating to such
    Legal Proceeding.
 
    Notwithstanding the foregoing or anything herein to the contrary, in no
event shall any party hereto be required under this Section 5.10 to make
arrangements for or to effect the sale, cessation, or other disposition of
product lines or businesses or take any action materially adverse to such party.
 
    5.11  CERTAIN NOTIFICATIONS.  The Company shall promptly notify Parent in
writing of the occurrence of any event that will or could reasonably be expected
to result in the failure by the Company or its affiliates to satisfy any of the
conditions specified in Section 6.1 or 6.2. Parent shall promptly notify the
Company in writing of the occurrence of any event that will or could reasonably
be expected to result in the failure by Parent or its affiliates to satisfy any

    in accordance with generally accepted accounting principles, Accounting
    Principles Board Opinion No. 16 and all published rules, regulations and

    or arrangement established or maintained by Parent, the Company or any of
    their respective subsidiaries, employees of the Company and its

    Subsidiaries, following the Effective Time ("Continuing Employees") under
    any welfare benefit plans that such Continuing Employees may be eligible to

    periods that are already in effect with respect to such Continuing Employees
    and that have not been satisfied as of the Effective Time, and (ii) provide

Accounting Principles Board and applicable SEC rules and regulations. Between
the date of this Agreement and the Effective Time, Parent and the Company each
shall use reasonable best efforts to cause the characterization of the Merger as
a pooling of interests for accounting purposes if such a characterization were
jeopardized by action taken by Parent or the Company, respectively, prior to the
date of this Agreement. Following the Effective Time, Parent shall not knowingly
take any action, or fail to take any action, that would jeopardize the
characterization of the Merger as a "pooling of interests" transaction for
accounting purposes.

Section 5.20. The Company shall use commercially reasonable efforts to cause
Gray Cary Ware & Freidenrich LLP to deliver to the Company a legal opinion,
satisfying the requirements of Item 601 of Regulation S-K promulgated under the
1933 Act and dated as of a date that is no more than two business days prior to
the date of filing of the Registration Statement and as of the Closing Date, to
the effect that the Merger will constitute a reorganization within the meaning
of Section 368(a) of the Code, based in part on the tax representation letters
described in this Section 5.20.

    Superior Proposal and the Company notifies Parent in writing that it intends
    to enter into such agreement, attaching the most current version of such
    agreement to such notice, (ii) Parent does not make, within ten business
    days after receipt of the Company's written notice of its intention to enter
    into a letter of intent or binding agreement for a Superior Proposal, any
    offer that the Board of Directors of the Company reasonably and in good
    faith determines, after consultation with its financial and legal advisors,
    is at least as favorable to the stockholders of the Company as the Superior
    Proposal and during such ten business-day period the Company reasonably
    considers and discusses in good faith all proposals submitted by Parent and,

    available funds to an account designated by Parent for such purpose), a fee
    equal to $400,000.
 
        (b) The Company acknowledges that the agreements contained in this
    Section 7.2 are an integral part of the transactions contemplated by this
    Agreement and are not a penalty, and that, without these agreements, Parent
    would not enter into this Agreement. If the Company fails to pay promptly
    the fee due pursuant to Section 7.2(a), the Company shall also pay to
    Parent's costs and expenses (including legal fees and expenses) in
    connection with any action, including the filing of any lawsuit or other
    legal action, taken to collect payment, together with interest on the amount
    of the unpaid fee under this section, accruing from its due date, at an
    interest rate per annum equal to two percentage points in excess of the
    prime commercial lending or reference rate quoted by U.S. Bank National
    Association. Any change in the interest rate hereunder resulting from a
    change in such prime or reference rate shall be effective at the beginning
    of the day of such change in such rate.
 
        (c) Parent agrees that the payment provided for in Section 7.2(a) shall
    be the sole and exclusive remedy of Parent upon termination of this
    Agreement pursuant to Section 7.1(e) and 7.1(f), as the case may be, and
    such remedy shall be limited to the sum stipulated in such Section 7.2(a),
    regardless of the circumstances giving rise to such termination; provided,
    however, that nothing herein shall relieve any party from liability for the
    willful breach of any of its representations, warranties, covenants or
    agreements set forth in this Agreement. In no event shall the Company be
    required to pay to Parent more than one fee pursuant to Section 7.2(a).
    Except as otherwise provided in this paragraph, in the event of the
    termination of this Agreement pursuant to any paragraph of Section 7.1, the
    obligations of the parties to consummate the Merger will expire, and none of
    the parties will have any further obligations under this Agreement except
    pursuant to Sections 5.4(b), 5.8, 7.2(a), 7.2(b) and 7.2(c) and Article 8.
 
                            ARTICLE 8 MISCELLANEOUS
 
    8.1  AMENDMENT AND MODIFICATION.  Subject to applicable law, this Agreement
may be amended, modified, or supplemented only by written agreement of Parent,
Merger Subsidiary, and the Company at any time prior to the Effective Time with
respect to any of the terms contained herein; provided, however, that, after the
approval of this Agreement by the stockholders of the Company, no amendment may
be made which would reduce the amount or change the type of consideration into
which each share of Company Common Stock shall be converted upon consummation of
the Merger or which would otherwise require stockholder approval under
applicable law unless such stockholder approval shall have been obtained. This
Agreement may not be amended except by an instrument in writing signed on behalf
of each of the parties hereto.
 
    8.2  WAIVER OF COMPLIANCE; CONSENTS.  Any failure of Parent or Merger
Subsidiary on the one hand, or the Company on the other hand, to comply with any
obligation, covenant, agreement, or condition herein may be waived by the
Company or Parent, respectively, only by a written instrument signed by an
officer of the party granting such waiver, but such waiver or failure to insist
upon strict compliance with such obligation, covenant, agreement, or condition
shall not operate as a waiver of, or estoppel with respect to, any subsequent or
other failure. Whenever this Agreement
 
                                      A-39
<PAGE>
requires or permits consent by or on behalf of any party hereto, such consent
shall be given in writing. Merger Subsidiary agrees that any consent or waiver
of compliance given by Parent hereunder shall be conclusively binding upon
Merger Subsidiary, whether or not given expressly on its behalf.
 
    8.3  INVESTIGATION; SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The
respective representations and warranties of Parent and the Company contained
herein or in any certificates or other documents delivered prior to or at the
Closing shall not be deemed waived or otherwise affected by any investigation
made by any party hereto. The representations, warranties and agreements in this
Agreement and in any certificate delivered pursuant hereto shall terminate at
the Effective Time, except that the agreements set forth in Article I and
Sections 5.7(b), 5.8, 5.9, 5.16, 5.17, 5.18, 5.19, 5.21 and this Article VIII
shall survive the Effective Time.

binding upon and inure to the benefit of the parties hereto and their respective

enforced by the beneficiaries thereof.
 
    8.6  GOVERNING LAW.  Except to the extent that Delaware law is applicable to
the duties of the Company's Board of Directors, this Agreement shall be governed
by the substantive laws of the State of Minnesota (regardless of the laws that
might otherwise govern under applicable Minnesota principles of conflicts of
law). The parties hereby (i) agree and consent to be subject to the jurisdiction
of any state or federal court in the state of Delaware or in Minneapolis or St.
Paul, Minnesota or Ann Arbor, Michigan, with respect to all actions and
proceedings arising out of or relating to this Agreement; (ii) agree that all
claims with respect to any such action or proceeding may be heard and determined

counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.
 
    8.8  KNOWLEDGE.  As used in this Agreement or the instruments, certificates
or other documents required hereunder, the term "knowledge" of a party hereto
shall mean actual knowledge of the directors or executive officers of such

contained in this Agreement are inserted for reference purposes only and shall
not affect the meaning or interpretation of this Agreement. This Agreement shall

the parties hereto in respect of the subject matter contained herein. This
Agreement and the Confidentiality Agreement supersede all prior agreements and
the understandings between the parties with respect to such subject matter,
whether written or oral.
 
    8.12  SEVERABILITY.  If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated by this Agreement is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in a mutually acceptable
manner in order that the transactions contemplated by this Agreement be
consummated as originally contemplated to the fullest extent possible.
 
    8.13  SPECIFIC PERFORMANCE.  The parties hereto agree that irreparable
damage would occur in the event any provision of this Agreement was not
performed in accordance with the terms hereof and that the parties shall be
entitled to specific performance of the terms hereof, in addition to any other
remedy at law or in equity.

Confidential
 
The Board of Directors
DSP Technology, Inc.
795 Highland Drive
Ann Arbor, MI 48108
 
Gentlemen:
 
    You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of common stock (the "Common
Stock") of DSP Technology, Inc. ("DSP" or the "Company") of the consideration to
be received by such shareholders in connection with the proposed merger of
Badger Merger Corp. ("Merger Sub"), a wholly-owned subsidiary of MTS Systems
Corporation ("MTS"), with and into DSP (the "Proposed Transaction") pursuant to
the Agreement and Plan of Merger to be dated as of March 23, 1999, among MTS,
Merger Sub, and DSP (the "Agreement").
 
    We understand that the terms of the Agreement provide, among other things,
that all of the issued and outstanding shares of Common Stock and options to
purchase shares of Common Stock shall be converted into the right to receive an
aggregate of 2,077,000 shares of common stock of MTS, as more fully set forth in
the Agreement. For purposes of this opinion, we have assumed that the Proposed
Transaction will qualify as a tax-free reorganization under the United States
Internal Revenue Code for the shareholders of the Company and that the Proposed
Transaction will be accounted for as a pooling of interests.
 
    Hambrecht & Quist LLC ("Hambrecht & Quist"), as part of its investment
banking services, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, strategic transactions,
corporate restructurings, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate
and other purposes. We have acted as a financial advisor to the Board of
Directors of DSP in rendering our opinion as to the fairness from a financial
point of view of the consideration to be received by the Company and its
stockholders in the Proposed Transaction, and we will receive a fee for our
services.
 
    In connection with our review of the Proposed Transaction, and in arriving
at our opinion, we have, among other things:
 
    (i) reviewed the publicly available consolidated financial statements of MTS
        for recent years and interim periods to date and certain other relevant
        financial and operating data of MTS (including its capital structure)
        made available to us from published sources;
 
    (ii) discussed the business, financial condition and prospects of MTS with
         certain members of senior management;
 
                                      B-1
<PAGE>
   (iii) reviewed the publicly available consolidated financial statements of
         DSP for recent years and interim periods to date and certain other
         relevant financial and operating data of DSP made available to us from
         published sources and from the internal records of DSP;
 
    (iv) reviewed certain internal financial and operating information,
         including certain projections, relating to DSP prepared by the
         management of DSP;
 
    (v) discussed the business, financial condition and prospects of DSP with
        certain members of senior management;
 
    (vi) reviewed the recent reported prices and trading activity for the common
         stocks of MTS and DSP and compared such information and certain
         financial information for MTS and DSP with similar information for
         certain other companies engaged in businesses we consider comparable;
 
   (vii) reviewed the financial terms, to the extent publicly available, of
         certain comparable merger and acquisition transactions;
 
  (viii) reviewed a draft of the Agreement dated March 23, 1999; and
 
    (ix) performed such other analyses and examinations and considered such
         other information, financial studies, analyses and investigations and
         financial, economic and market data as we deemed relevant.
 
    In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning MTS or DSP considered in
connection with our review of the Proposed Transaction, and we have not assumed
any responsibility for independent verification of such information. We have not
prepared any independent valuation or appraisal of any of the assets or
liabilities of MTS or DSP, nor have we conducted a physical inspection of the
properties and facilities of either company. With respect to the financial
forecasts and projections made available to us and used in our analysis, we have
assumed that they reflect the best currently available estimates and judgments
of the expected future financial performance of MTS and DSP. For purposes of
this opinion, we have assumed that neither MTS nor DSP is a party to any pending
transactions, including external financings, recapitalizations or material
merger discussions, other than the Proposed Transaction and those activities
undertaken in the ordinary course of conducting their respective businesses. Our
opinion is necessarily based upon market, economic, financial and other
conditions as they exist and can be evaluated as of the date of this letter and
any change in such conditions would require a reevaluation of this opinion. We
express no opinion as to the price at which MTS common stock will trade
subsequent to the Effective Time (as defined in the Agreement). In rendering
this opinion, we have assumed that the proposed merger will be consummated
substantially on the terms discussed in the Agreement, without any waiver of any
material terms or conditions by any party thereto. We were not requested to, and
did not, solicit indications of interest from any other parties in connection
with a possible acquisition of, or business combination with, DSP.
 
    It is understood that this letter is for the information of the Board of
Directors only and may not be used for any other purpose without our prior
written consent; provided, however, that this letter may be reproduced in full
in the Proxy Statement/Prospectus. This letter does not constitute a
recommendation to any stockholder as to how such stockholder should vote on the
Proposed Transaction.
 
    Based upon and subject to the foregoing and after considering such other
matters as we deem relevant, we are of the opinion that as of the date hereof
the consideration to be received by the holders of the Common Stock in the
Proposed Transaction is fair to such holders from a financial point
 
                                      B-2

of view. We express no opinion, however, as to the adequacy of any consideration
received in the Proposed Transaction by MTS or any of its affiliates.
 
Very truly yours,
 
HAMBRECHT & QUIST LLC

                                    PART II
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 302A.521 of Minnesota Statutes requires the Registrant to indemnify
a person made or threatened to be made a party to a proceeding by reason of the
former or present official capacity of the person with respect to the
Registrant, against judgments, penalties, fines, including reasonable expenses,
if such person (1) has not been indemnified by another organization or employee
benefit plan for the same judgments, penalties, fines, including, without
limitation, excise taxes assessed against the person with respect to an employee
benefit plan, settlements, and reasonable expenses, including attorneys' fees
and disbursements, incurred by the person in connection with the proceeding with
respect to the same acts or omissions; (2) acted in good faith; (3) received no
improper personal benefit, and statutory procedure has been followed in the case
of any conflict of interest by a director; (4) in the case of a criminal
proceeding, had no reasonable cause to believe the conduct was unlawful; and (5)
in the case of acts or omissions occurring in the person's performance in the
official capacity of director or, for a person not a director, in the official
capacity of officer, committee member or employee, reasonably believed that the
conduct was in the best interests of the Registrant, or, in the case of
performance by a director, officer or employee of the Registrant as a director,
officer, partner, trustee, employee or agent of another organization or employee
benefit plan, reasonably believed that the conduct was not opposed to the best
interests of the Registrant. In addition, Section 302A.521, subd. 3, requires
payment by the Registrant, upon written request, of reasonable expenses in
advance of final disposition in certain instances. A decision as to required
indemnification is made by a disinterested majority of the Board of Directors
present at a meeting at which a disinterested quorum is present, or by a
designated committee of the Board, by special legal counsel, by the shareholders
or by a court. The Registrant's Bylaws provide for indemnification of officers,
directors and employees to the fullest extent provided by the Minnesota Business
Corporation Act, as it may be amended from time to time.
 
    As permitted by Section 302A.251 of the Minnesota Business Corporation Act,
the Articles of Incorporation of the Registrant eliminate the liability of the
directors of the Registrant for monetary damages arising from any breach of
fiduciary duties as a member of the Registrant's Board of Directors, except for
liability (a) for any breach of the director's duty of loyalty to the Registrant
or its shareholders; (b) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law; (c) under Sections
302A.559 or 80A.23 of the Minnesota Statutes; (d) for any transaction from which
a director derived an improper personal benefit; or (e) for any act or omission
that occurred prior to the adoption of these provisions in the Registrant's
Articles of Incorporation.
 
    The Registrant currently has in effect policies of insurance which provide
insurance protection to its directors and officers against some liabilities
which may be incurred by them on account of their services to the Registrant.

                                      II-2
<PAGE>
the Registrant pursuant to section 13 or section 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in the Registration
Statement;
 
        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof;
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering;
 
        (4) That, for purposes of determining any liability under the Securities
    Act of 1933, each filing of the Registrant's annual report pursuant to
    section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that
    is incorporated by reference in the Registration Statement shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof;
 
        (5) To respond to requests for information that is incorporated by
    reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
    Form, within one business day of receipt of such request, and to send the
    incorporated documents by first class mail or other equally prompt means.
    This includes information contained in documents filed subsequent to the
    effective date of the Registration Statement through the date of responding
    to the request;
 
        (6) That, prior to any public reoffering of the securities registered
    hereunder through use of a prospectus which is a part of this Registration
    Statement, by any person or party who is deemed to be an underwriter within
    the meaning of Rule 145(c), the issuer undertakes that such reoffering
    prospectus will contain the information called for by the applicable
    registration form with respect to reofferings by persons who may be deemed
    underwriters, in addition to the information called for by the other Items
    of the applicable form;
 
        (7) That every prospectus (i) that is filed pursuant to paragraph (6)
    immediately preceding, or (ii) that purports to meet the requirements of
    section 10(a) (3) of the Securities Act and is used in connection with an
    offering of securities subject to Rule 415, will be filed as a part of an
    amendment to the registration statement and will not be used until such
    amendment is effective, and that, for purposes of determining any liability
    under the Securities Act, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof; and
 
        (8) To supply by means of a post-effective amendment all information
    concerning a transaction, and the company being acquired involved therein,
    that was not the subject of and included in the Registration Statement when
    it became effective.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 20 above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     Re:  REGISTRATION STATEMENT ON FORM S-4

Ladies and Gentlemen:

     In connection with the Registration Statement on Form S-4 filed by MTS
Systems Corporation (the "Company") with the Securities and Exchange Commission
on April 28, 1999 relating to the registration of 2,077,000 shares of Common
Stock, $.25 par value (the "Shares"), to be issued by the Company in connection
with the proposed merger of a subsidiary of the Company with and into DSP
Technology Inc., a Delaware corporation, please be advised that as counsel to
the Company, upon examination of such corporate documents and records as we have
deemed necessary or advisable for the purposes of this opinion, it is our
opinion that:

     1.    The Company has been duly incorporated and is validly existing as a
           corporation in good standing under the laws of the State of
           Minnesota.

     2.    All necessary corporate action on the part of the Company has been
           taken to authorize the issuance of the Shares to be issued in
           connection with such merger and, when issued pursuant to the merger
           and paid for as contemplated by the Registration Statement, the
           Shares will be legally issued, fully paid and nonassessable.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the heading "Legal
Matters" in the Proxy Statement/Prospectus comprising a part of the Registration
Statement.

                              Very truly yours,

Board of Directors of
MTS Systems Corporation
14000 Technology Drive
Eden Prairie, MN 55344-2290

     RE:  FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER WITH DSP TECHNOLOGY INC.

Ladies and Gentlemen:

     You have requested that we render an opinion with respect to the material
United States federal income tax considerations related to the Merger whereby a
wholly-owned subsidiary ("Merger Sub") of MTS Systems Corporation ("Parent")
will merge into DSP Technology, Inc. (the "Company") (the "Merger").  

     We have examined the Agreement and Plan of Merger executed March 23, 1999
(the "Merger Agreement") and the Registration Statement on Form S-4
("Registration Statement") filed with the Securities and Exchange Commission on
April 28, 1999 under the Securities Act of 1933.  The Registration Statement
contains a Proxy Statement and a Prospectus (collectively, the "Joint Proxy
Statement/Prospectus").  Unless otherwise defined in this letter, terms defined
in the Joint Proxy Statement/Prospectus are used herein as defined therein.  

     We also have examined such matters of law, including the provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), proposed and finalized
Treasury regulations promulgated thereunder (the "Regulations"), and judicial
and administrative decisions, rulings and interpretations thereof currently in
effect, as we have deemed appropriate as a basis for our opinions set forth
below.  All section references herein are to the Code unless stated otherwise.

     In rendering this opinion, we have relied upon the current and continued
accuracy of the factual matters we have considered, including the recitals,
agreements, representations and warranties contained in or made pursuant to the
documents cited above, as well as the representations and warranties made by the
Company, Merger Sub and Parent to Lindquist & Vennum P.L.L.P. for purposes of
rendering this opinion.

     Based solely on the foregoing, and subject to the qualifications set forth
herein, we are of the opinion that if the Merger is effected in accordance with
the Merger Agreement and the above facts and representations:

<PAGE>

     1.   For federal income tax purposes, the Merger will constitute a
reorganization within the meaning of Section 368(a).

     2.   Subject to the foregoing and the fact that the discussion in the
Registration Statement under the heading "Material Federal Income Tax
Consequences" (the "Tax Discussion") is a summary and does not purport to
discuss all possible United States federal income tax consequences of the Merger
and sets forth additional limitations, qualifications, assumptions and caveats,
the Tax Discussion sets forth the material United States federal income tax
consequences of the Merger to holders of the Company's Common Stock who exchange
such stock for Parent Common Stock pursuant to the Merger Agreement.

     No opinion is expressed about the tax treatment of the proposed transaction
under other provisions of the Code and the Regulations or about the tax
treatment of any conditions existing at the time of, or effects resulting from,
the proposed transaction that are not specifically covered by the above
opinions.  The opinion also does not address the various state, local or foreign
tax consequences that may result from the Merger or other transactions
contemplated by the Merger Agreement.  

     The opinions expressed herein are rendered as of the date hereof and are
based on the Code, proposed and finalized Regulations, and judicial and
administrative decisions, rulings and interpretations, all of which are subject
to change with no assurance that changes will not be made retroactively.

     An opinion of legal counsel represents an expression of legal counsel's
professional judgment regarding the subject matter of the opinion and, unlike
private letter rulings issued by the Internal Revenue Service (the "Service"),
is not binding on the Service and has no official status of any kind.

     This opinion is for the sole use of the Board of Directors of Parent and
may not be relied upon by any other entity or individual.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the heading "Legal
Matters" in the Joint Proxy Statement/Prospectus.

                              Sincerely,



                              /s/ Lindquist & Vennum P.L.L.P.

April 28, 1999


DSP Technology Inc.
795 Highland Drive
Ann Arbor, MI  48108

Ladies and Gentlemen:

This opinion is being delivered to you in accordance with the requirements of
Item 601(b)(8) of Regulation S-K under the Securities Act of 1933, as amended,
in connection with the filing of a registration statement on Form S-4 of a Proxy
Statement/Prospectus (the "Registration Statement") pursuant to the Agreement
and Plan of Merger dated as of March 23, 1999 (the "Reorganization Agreement")
by and among MTS Systems Corporation, a Minnesota corporation ("Parent"), Badger
Merger Corp., a Delaware corporation and a wholly-owned subsidiary of Parent
("Merger Sub") and DSP Technology Inc., a Delaware corporation (the "Company"). 
Pursuant to the Reorganization Agreement, Merger Sub will merge with and into
the Company (the "Merger").  

Unless otherwise defined, capitalized terms referred to herein have the meanings
set forth in the Reorganization Agreement.  All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the
"Code").

We have acted as legal counsel to the Company in connection with the preparation
and execution of the Reorganization Agreement.  As such, and for the purpose of
rendering this opinion, we have examined and are relying upon (without any
independent investigation or review thereof) the truth and accuracy, at all
relevant times, of the statements, covenants, representations and warranties
contained in the following documents (including all schedules and exhibits
thereto): (1) the Reorganization Agreement; (2) representations and warranties
made to us by Parent, Merger Sub and the Company (the "Tax Representation
Letters"); and (3) such other instruments and documents related to the
formation, organization and operation of Parent, Merger Sub and the Company or
to the consummation of the Merger and the transactions contemplated thereby as
we have deemed necessary or appropriate.

In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:

     1.   Original documents (including signatures) are authentic, documents
submitted to us as copies conform to the original documents, and there has been
(or will be by the Effective Time

<PAGE>

of the Merger) due execution and delivery of all documents where due execution
and delivery are prerequisites to effectiveness thereof;

     2.   Any representation or statement made "to the best of knowledge" or
similarly qualified is correct without such qualification.  As to all matters in
which a person or entity making a representation referred to above has
represented that such person or entity either is not a party to, does not have,
or is not aware of, any plan or intention, understanding or agreement, there is
in fact no such plan, intention, understanding or agreement;  

     3.   All statements, descriptions and representations contained in any of
the documents referred to herein or otherwise made to us (including, but not
limited to the Tax Representation Letters) are true and correct as of the date
hereof and at the Effective Time, and no actions have been (or will be) taken
which are inconsistent with such statements, descriptions and representations;

     4.   The Merger will be consummated in accordance with the Reorganization
Agreement (and without any waiver, breach or amendment of any of the material
provisions thereof), will be effective under the applicable state law, and will
be reported by Parent and the Company on their respective federal income tax
returns in a manner consistent with the opinion set forth below; and

     5.   An opinion of Lindquist & Vennum P.L.L.P., counsel to Parent,
substantially identical in substance to this opinion, has been delivered and not
withdrawn.

Based on our examination of the foregoing items and subject to the limitations,
qualifications, assumptions, and caveats set forth herein, we are of the opinion
that:

     1.   For federal income tax purposes, the Merger will be constitute a
reorganization within the meaning of Section 368(a) of the Code; and

     2.   Subject to the foregoing and the fact that the discussion in the
Registration Statement under the heading "Material Federal Income Tax
Consequences" (the "Discussion") is a summary and does not purport to discuss
all possible United Stated federal income tax consequences of the Merger and
sets forth additional limitations, qualifications, assumptions and caveats, the
Discussion sets forth the material United States federal income tax consequences
of the Merger to holders of Company Common Stock who exchange such stock for
Parent Common Stock pursuant to the Reorganization Agreement.  

This opinion does not address the various state, local or foreign tax
consequences that may result from the Merger or other transactions contemplated
by the Reorganization Agreement.  In addition, no opinion is expressed as to any
federal income tax consequences of the Merger or the other transactions
contemplated by the Reorganization Agreement except as specifically set forth
herein, and this opinion may not be relied upon except with respect to the
consequences specifically discussed herein.    

No opinion is expressed as to any transaction other than the Merger as described
in the

<PAGE>

Reorganization Agreement or to any transaction whatsoever, including the Merger,
if all the transactions described in the Reorganization Agreement are not
consummated in accordance with the terms of such Reorganization Agreement and
without waiver or breach of any material provision thereof or if all of the
representations, warranties, statements and assumptions upon which we relied are
not true and accurate at all relevant times. In the event any one of the
statements, representations, warranties or assumptions upon which we have relied
to issue this opinion is incorrect, our opinion might be adversely affected and
may not be relied upon.

This opinion represents and is based upon our best judgment regarding the
application of federal income tax laws arising under the Code, existing judicial
decisions, administrative regulations and published rulings and procedures.  Our
opinion is not binding upon the Internal Revenue Service or the courts, and the
Internal Revenue Service is not precluded from successfully asserting a contrary
position.  Furthermore, no assurance can be given that future legislative,
judicial or administrative changes, on either a prospective or retroactive
basis, would not adversely affect the accuracy of the conclusions stated herein.
Nevertheless, we undertake no responsibility to advise you of any new
developments in the application or interpretation of the federal income tax
laws.

This opinion has been delivered to you only for the purposes stated.  It is
intended for the benefit of the Company and the stockholders of the Company and
may not be relied upon for any other purpose or by any other person or entity,
and may not be made available to any other person or entity without our prior
written consent.  We hereby consent, however, to the use of this opinion as an
exhibit to the Registration Statement and further consent to the use of our name
wherever appearing in the Registration Statement, including the Proxy
Statement/Prospectus constituting a part thereof, and any amendments thereto.   

Very truly yours,
