                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations
        Thermo Voltek Corp. (the Company) designs, manufactures, and markets
    electromagnetic compatibility (EMC) testing instruments, high-voltage
    power-conversion systems, and programmable power amplifiers. The
    Company's EMC testing instruments simulate pulsed electromagnetic
    interference (pulsed EMI), radio frequency interference (RFI), and
    changes in AC voltage, to allow manufacturers of electronic systems and
    integrated circuits to test for resistance to those conditions. The
    Company's high-voltage power conversion systems transform utility-
    supplied AC power into DC voltages and currents required by the user. The
    Company's programmable power amplifiers have applications in EMC testing
    and other areas. The Company also provides EMC consulting and
    systems-integration services and distributes EMC-related products.

    Relationship with Thermedics Inc. and Thermo Electron Corporation
        As of December 28, 1996, Thermedics Inc. (Thermedics) owned 4,971,333
    shares of the Company's common stock, representing 51% of such stock
    outstanding. Thermedics is a 55%-owned subsidiary of Thermo Electron
    Corporation (Thermo Electron). As of December 28, 1996, Thermo Electron
    owned 51,700 shares of the Company's common stock, representing 0.53% of
    such stock outstanding.

    Principles of Consolidation
        The accompanying financial statements include the accounts of the
    Company and its wholly owned subsidiaries. All material intercompany
    accounts and transactions have been eliminated.

    Fiscal Year
        The Company has adopted a fiscal year ending the Saturday nearest
    December 31. References to 1996, 1995, and 1994 are for the fiscal years
    ended December 28, 1996, December 30, 1995, and December 31, 1994,
    respectively.

    Revenue Recognition
        The Company recognizes product revenues upon shipment of its
    products. The Company provides a reserve for its estimate of warranty
    costs at the time of shipment. Revenues and profits on substantially all
    contracts are recognized using the percentage-of-completion method.
    Revenues recorded under the percentage-of-completion method were
    $4,806,000 in 1996, $2,884,000 in 1995, and $330,000 in 1994. The
    percentage of completion is determined by relating either the actual
    costs or actual labor incurred to date to management's estimate of total
    costs or total labor, respectively, to be incurred on each contract. If a
    loss is indicated on any contract in process, a provision is made
    currently for the entire loss. The Company's contracts generally provide
    for billing of customers upon the attainment of certain milestones
    specified in each contract. Revenues earned on contracts in process in
    excess of billings are included in inventories in the accompanying

    balance sheet and were not material at year-end 1996 and 1995. There are
    no significant amounts included in the accompanying balance sheet that
    are not expected to be recovered from existing contracts at current
    contract values, or that are not expected to be collected within one
    year, including amounts billed but not paid under retainage provisions.

    Stock-based Compensation Plans
        The Company applies Accounting Principles Board Opinion (APB) No. 25,
    "Accounting for Stock Issued to Employees" and related interpretations in
    accounting for its stock-based compensation plans (Note 4). Accordingly,
    no accounting recognition is given to stock options granted at fair
    market value until they are exercised. Upon exercise, net proceeds,
    including tax benefits realized, are credited to equity.

    Income Taxes
        In accordance with Statement of Financial Accounting Standards (SFAS)
    No. 109, "Accounting for Income Taxes," the Company recognizes deferred
    income taxes based on the expected future tax consequences of differences
    between the financial statement basis and the tax basis of assets and
    liabilities calculated using enacted tax rates in effect for the year in
    which the differences are expected to be reflected in the tax return.

    Earnings per Share
        Primary earnings per share has been computed based on the weighted
    average number of shares outstanding and, in 1996 and 1995, included
    common stock equivalents (stock options) computed using the treasury
    stock method. In 1994, the effect of common stock equivalents was
    immaterial. Fully diluted earnings per share has been computed, where
    dilutive, assuming the conversion of the Company's subordinated
    convertible obligations and elimination of the related interest expense,
    as well as the exercise of stock options and their related income tax
    effects.

    Stock Split
        All share and per share information, except for share information in
    the accompanying 1995 balance sheet, has been restated to reflect a
    three-for-two stock split, effected in the form of a 50% stock dividend,
    distributed in August 1996.

    Cash and Cash Equivalents
        As of December 28, 1996, $16,623,000 of the Company's cash
    equivalents were invested in a repurchase agreement with Thermo Electron.
    Under this agreement, the Company in effect lends excess cash to Thermo
    Electron, which Thermo Electron collateralizes with investments
    principally consisting of U.S. government agency securities, corporate
    notes, commercial paper, money market funds, and other marketable
    securities, in the amount of at least 103% of such obligation. The
    Company's funds subject to the repurchase agreement are readily
    convertible into cash by the Company. The repurchase agreement earns

    carried at cost, which approximates market value.

    Inventories
        Inventories are stated at the lower of cost (on a first-in, first-out
    basis) or market value and include materials, labor, and manufacturing
    overhead. The components of inventories are as follows:

    Cost in Excess of Net Assets of Acquired Companies
        The excess of cost over the fair value of net assets of acquired
    companies is amortized using the straight-line method over periods not
    exceeding 40 years. Accumulated amortization was $1,371,000 and $943,000
    at year-end 1996 and 1995, respectively. The Company assesses the future
    useful life of this asset whenever events or changes in circumstances
    indicate that the current useful life has diminished. The Company
    considers the future undiscounted cash flows of the acquired companies in
    assessing the recoverability of this asset. If impairment has occurred,
    any excess of carrying value over fair value is recorded as a loss.

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies
        (continued)

    Foreign Currency
        All assets and liabilities of the Company's foreign subsidiaries are
    translated at year-end exchange rates, and revenues and expenses are
    translated at average exchange rates for the year in accordance with SFAS
    No. 52, "Foreign Currency Translation." Resulting translation adjustments
    are reflected as a separate component of shareholders' investment titled
    "Cumulative translation adjustment." Foreign currency transaction gains
    and losses are included in the accompanying statement of income and are
    not material for the three years presented.

    Use of Estimates
        The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities,
    disclosure of contingent assets and liabilities at the date of the
    financial statements, and the reported amounts of revenues and expenses
    during the reporting period. Actual results could differ from those
    estimates.

    2.  Available-for-sale Investments

        Effective January 2, 1994, the Company adopted SFAS No. 115,
    "Accounting for Certain Investments in Debt and Equity Securities." In
    accordance with SFAS No. 115, the Company's debt and marketable equity
    securities are considered available-for-sale investments in the
    accompanying balance sheet and are carried at market value, with the
    difference between cost and market value, net of related tax effects,
    recorded currently as a component of shareholders' investment titled "Net
    unrealized gain (loss) on available-for-sale investments." Effect of
    change in accounting principle in the accompanying 1994 statement of
    shareholders' investment represents the unrealized gain, net of related
    tax effects, pertaining to available-for-sale investments held by the
    Company on January 2, 1994.

    years. Actual maturities may differ from contractual maturities as a
    result of the Company's intent to sell these securities prior to maturity
    and as a result of put and call options that enable the Company, the
    issuer, or both to redeem these securities at an earlier date.

    3.  Acquisitions

        In July 1996, the Company acquired substantially all of the assets,
    subject to certain liabilities, of Pacific Power Source Corporation
    (Pacific Power) for $6,300,000 in cash, including the repayment of
    $800,000 in debt. Pacific Power manufactures programmable power
    amplifiers that can be incorporated into EMC test equipment to assess how
    well electronics tolerate normal variations in the quality and quantity
    of AC voltage. These amplifiers are also used in other kinds of test
    equipment and in application-specific power supplies.
        In March 1995, the Company acquired substantially all of the assets,
    subject to certain liabilities, of Kalmus Engineering Incorporated and
    R.F. Power Labs, Incorporated (collectively, Kalmus) for $3,755,000 in
    cash. Kalmus is a manufacturer of radio frequency power amplifiers and
    systems used to test products for immunity to RFI and in medical imaging
    and telecommunications applications.
        Additionally, the Company acquired a component-reliability product
    line in 1995 for approximately $402,000 in cash.
        In July 1994, the Company's Comtest Limited subsidiary acquired
    Verifier Systems Limited (Verifier) for approximately $1,330,000 in cash.
    Verifier is a United Kingdom-based manufacturer of test equipment that
    performs electrical stress tests for semiconductor devices.
        These acquisitions have been accounted for using the purchase method
    of accounting, and their results of operations have been included in the
    accompanying financial statements from their respective dates of
    acquisition. The aggregate cost of these acquisitions exceeded the
    estimated fair value of the acquired net assets by $8,707,000, which is
    being amortized over periods not exceeding 40 years. Allocation of the
    purchase price for these acquisitions was based on estimates of the fair
    value of the net assets acquired and, for Pacific Power, is subject to
    adjustment upon finalization of the purchase price allocation.
        Based on unaudited data, the following table presents selected
    financial information for the Company and Kalmus, on a pro forma basis,
    assuming that the Company and Kalmus had been combined since the
    beginning of 1994. Pro forma data is not presented for the Company's
    other acquisitions since they were not material to the Company's results
    of operations.

        The pro forma results are not necessarily indicative of future
    operations or the actual results that would have occurred had the
    acquisition of Kalmus been made at the beginning of 1994.

    4.  Employee Benefit Plans

    Stock-based Compensation Plans

    Stock Option Plans
    ------------------
        The Company has stock-based compensation plans for its key employees,
    directors, and others. Two of the plans, adopted in 1985 and 1990, permit
    the grant of nonqualified and incentive stock options. A third plan,
    adopted in 1994, permits the grant of a variety of stock and stock-based
    awards as determined by the human resources committee of the Company's
    Board of Directors (the Board Committee), including restricted stock,
    stock options, stock bonus shares, or performance-based shares. To date,
    only nonqualified stock options have been awarded under this plan. The
    option recipients and the terms of options granted under these plans are
    determined by the Board Committee. Generally, options granted to date are
    exercisable immediately, but are subject to certain transfer restrictions
    and the right of the Company to repurchase shares issued upon exercise of
    the options at the exercise price, upon certain events. The restrictions
    and repurchase rights generally lapse ratably over a five to ten year
    period, depending on the term of the option, which may range from five to
    twelve years. Nonqualified stock options may be granted at any price
    determined by the Board Committee, although incentive stock options must
    be granted at not less than the fair market value of the Company's stock
    on the date of grant. To date, all options have been granted at fair
    market value. The Company also has a directors' stock option plan,
    adopted in 1993, that provides for the grant of stock options to outside
    directors pursuant to a formula approved by the Company's shareholders.
    Options awarded under this plan are exercisable six months after the date
    of grant and expire three or seven years after the date of grant. In
    addition to the Company's stock-based compensation plans, certain
    officers and key employees may also participate in the stock-based
    compensation plans of Thermo Electron and Thermedics.

    Employee Stock Purchase Program
    -------------------------------
        Substantially all of the Company's full-time U.S. employees are
    eligible to participate in an employee stock purchase program sponsored
    by the Company and Thermo Electron. Under this program, shares of the
    Company's and Thermo Electron's common stock can be purchased at the end
    of a 12-month period at 95% of the fair market value at the beginning of
    the period, and the shares purchased are subject to a six-month resale
    restriction. Prior to November 1, 1995, the applicable shares of common
    stock could be purchased at 85% of the fair market value at the beginning
    of the period, and the shares purchased were subject to a one-year resale
    restriction. Shares are purchased through payroll deductions of up to 10%
    of each participating employee's gross wages. During 1996, 1995, and
    1994, the Company issued 8,891 shares, 10,308 shares, and 4,820 shares,
    respectively, of its common stock under this program.

    4.  Employee Benefit Plans (continued)

    Pro Forma Stock-based Compensation Expense
        In October 1995, the Financial Accounting Standards Board issued SFAS
    No. 123, "Accounting for Stock-based Compensation," which sets forth a
    fair-value based method of recognizing stock-based compensation expense.
    As permitted by SFAS No. 123, the Company has elected to continue to
    apply APB No. 25 to account for its stock-based compensation plans. Had
    compensation cost for awards in 1996 and 1995 under the Company's
    stock-based compensation plans been determined based on the fair value at
    the grant dates consistent with the method set forth under SFAS No. 123,
    the effect on the Company's net income and earnings per share would have
    been as follows:

    (In thousands except per share amounts)                1996         1995
    ------------------------------------------------------------------------
    Net income:
      As reported                                       $4,469       $2,672
      Pro forma                                          4,294        2,601
    Primary earnings per share:
      As reported                                          .51          .40
      Pro forma                                            .49          .39
    Fully diluted earnings per share:
      As reported                                          .38          .28
      Pro forma                                            .37          .28

        Because the method prescribed by SFAS No. 123 has not been applied to
    options granted prior to January 1, 1995, the resulting pro forma
    compensation expense may not be representative of the amount to be
    expected in future years. Pro forma compensation expense for options
    granted is reflected over the vesting period; therefore, future pro forma
    compensation expense may be greater as additional options are granted.
        The fair value of each option grant was estimated on the grant date
    using the Black-Scholes option-pricing model with the following
    weighted-average assumptions:

                                                           1996        1995
    -----------------------------------------------------------------------
    Volatility                                             41%          41%
    Risk-free interest rate                               6.6%         6.3%
    Expected life of options                           5 years    4.4 years

        The Black-Scholes option-pricing model was developed for use in
    estimating the fair value of traded options that have no vesting
    restrictions and are fully transferable. In addition, option-pricing
    models require the input of highly subjective assumptions, including
    expected stock price volatility. Because the Company's employee stock
    options have characteristics significantly different from those of traded
    options, and because changes in the subjective input assumptions can
    materially affect the fair value estimate, in management's opinion, the
    existing models do not necessarily provide a reliable single measure of
    the fair value of its employee stock options.

   6.  Income Taxes (continued)

       The Company receives a tax deduction upon exercise of nonqualified
   stock options by employees for the difference between the exercise price
   and the market price of the Company's common stock on the date of exercise.
   The provision for income taxes that is currently payable does not reflect
   $112,000, $166,000, and $39,000 of such benefits allocated to capital in
   excess of par value in 1996, 1995, and 1994, respectively.
       The provision for income taxes in the accompanying statement of income
   differs from the provision calculated by applying the statutory federal
   income tax rate of 34% to income before provision for income taxes due to
   the following:

   Thermo Voltek Corp.                               1996 Financial Statements

                   Notes to Consolidated Financial Statements

   6.  Income Taxes (continued)

       The 1995 valuation allowance primarily related to uncertainty
   surrounding the realization of tax loss and credit carryforwards and
   certain other tax assets of the Company. The valuation allowance was
   eliminated in 1996. Of the total decrease to the valuation allowance,
   $684,000 relates to reduced uncertainty surrounding the realizability of
   the tax loss and credit carryforwards, and was recorded as a decrease in
   the provision for income taxes in 1996. The remaining decrease in the
   valuation allowance primarily relates to the elimination of related tax
   loss and credit carryforwards due to the inability to obtain a benefit
   prior to the expiration thereof. The provision for income taxes was reduced
   by $630,000 and $290,000 in 1995 and 1994, respectively, as a result of
   changes in the amount of estimated tax assets and the utilization of a
   portion of the Company's tax loss and credit carryforwards.
       As of December 28, 1996, the Company has federal tax net operating loss
   carryforwards of approximately $2.5 million, subject to the limitations
   described below. These net operating loss carryforwards will begin to
   expire in 1998. Pursuant to U.S. Internal Revenue Code Sections 382 and
   383, the utilization of the net operating loss carryforwards is limited to
   the tax benefit of a deduction of approximately $240,000 per year with any
   unused portion of this annual limitation carried forward to future years.
       A provision has not been made for U.S. or additional foreign taxes on
   $1.8 million of undistributed earnings of foreign subsidiaries that could
   be subject to tax if remitted to the U.S. because the Company currently
   plans to keep these amounts permanently reinvested overseas. The Company
   believes that any additional U.S. tax liability due upon remittance of such
   earnings would be immaterial due to available U.S. foreign tax credits.

   7.  Commitments

       The Company occupies office and operating facilities under operating
   leases expiring at various dates through 2003. The accompanying statement
   of income includes expenses from operating leases of $555,000, $381,000,
   and $363,000 in 1996, 1995, and 1994, respectively. The future minimum
   payments due under noncancellable operating leases as of December 28, 1996,
   are $749,000 in 1997; $758,000 in 1998; $770,000 in 1999; $764,000 in 2000;
   and $613,000 in 2001 and thereafter. Total future minimum lease payments
   are $3,654,000.

   8.  Short- and Long-term Obligations

   Short-term Obligations
       The Company has lines of credit denominated in certain foreign
   currencies to borrow up to approximately $2,625,000. Amounts borrowed under
   these arrangements are classified as notes payable in the accompanying
   balance sheet. The weighted average interest rate for these borrowings at
   year-end 1996 and 1995 was 6.3% and 7.6%, respectively. Unused lines of
   credit were $959,000 at December 28, 1996.

   Long-term Obligations
       Long-term obligations of the Company are as follows:

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

   (a) In lieu of issuing shares of the Company's common stock upon
       conversion, the Company has the option to pay holders of the debentures
       cash equal to the weighted average market price of the Company's common
       stock on the trading date prior to conversion.
   (b) Represents an obligation to Thermedics.

       During 1996 and 1995, $17,395,000 and $9,111,000, respectively, of
   convertible obligations were converted into shares of the Company's common
   stock. In 1995, the Company repurchased $149,000 principal amount of the 3
   3/4% subordinated convertible debentures.
       Short- and long-term obligations in the accompanying balance sheet are
   guaranteed on a subordinated basis by Thermo Electron. Thermedics has
   agreed to reimburse Thermo Electron in the event Thermo Electron is
   required to make a payment under the guarantees.
       See Note 10 for fair value information pertaining to the Company's
   long-term obligations.

   9.  Related Party Transactions

   Corporate Services Agreement
       The Company and Thermo Electron have a corporate services agreement
   under which Thermo Electron's corporate staff provides certain
   administrative services, including certain legal advice and services, risk
   management, certain employee benefit administration, tax advice and
   preparation of tax returns, centralized cash management, and certain
   financial and other services, for which the Company pays Thermo Electron
   annually an amount equal to 1.0% of the Company's revenues. The Company
   paid an annual fee equal to 1.20% and 1.25% of the Company's revenues in
   1995 and 1994, respectively. The annual fee is reviewed and adjusted
   annually by mutual agreement of the parties. For these services, the
   Company was charged $485,000, $436,000, and $296,000 in 1996, 1995, and
   1994, respectively. The corporate services agreement is renewed annually
   but can be terminated upon 30 days' prior notice by the Company or upon the
   Company's withdrawal from the Thermo Electron Corporate Charter (the Thermo
   Electron Corporate Charter defines the relationship among Thermo Electron
   and its majority-owned subsidiaries). Management believes that the service

                   Notes to Consolidated Financial Statements

    9.  Related Party Transactions (continued)

    fee charged by Thermo Electron is reasonable and that such fees are
    representative of the expenses the Company would have incurred on a
    stand-alone basis. For additional items such as employee benefit plans,
    insurance coverage, and other identifiable costs, Thermo Electron charges
    the Company based upon costs attributable to the Company.

    Repurchase Agreement
        The Company invests excess cash in a repurchase agreement with
    Thermo Electron as discussed in Note 1.

    Available-for-sale Investments
        At December 28, 1996, and December 30, 1995, the Company's
    available-for-sale investments included $1,399,000 and $1,517,000
    (amortized cost of $1,336,000 and $1,339,000), respectively, of 6 1/2%
    subordinated convertible debentures due 1997, which were purchased on the
    open market. These debentures have a par value of $1,300,000 and were
    issued by Thermo TerraTech Inc., a majority-owned subsidiary of Thermo
    Electron.

    Subordinated Convertible Notes
        See Note 8 for subordinated convertible notes of the Company held by
    Thermedics.

    10. Fair Value of Financial Instruments

        The Company's financial instruments consist mainly of cash and cash
    equivalents, available-for-sale investments, accounts receivable, notes
    payable, accounts payable, due to parent company and affiliates, and
    subordinated convertible obligations. The carrying amounts of these
    financial instruments, with the exception of available-for-sale
    investments and subordinated convertible obligations, approximate fair
    value due to their short-term nature. 
        Available-for-sale investments are carried at fair value in the
    accompanying balance sheet. The fair values were determined based on
    quoted market prices. See Note 2 for fair value information pertaining to
    these financial instruments.
        The fair value of the Company's subordinated convertible obligations
    was determined based on quoted market prices. The carrying amount and
    fair value of the Company's subordinated convertible obligations are as
    follows:
                                       1996                    1995

      obligations (1)           $ 19,345    $ 38,836    $36,740    $61,449

    (1) The fair value of subordinated convertible obligations exceeds the

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors of Thermo Voltek Corp.:

        We have audited the accompanying consolidated balance sheet of Thermo
    Voltek Corp. (a Delaware corporation and 51%-owned subsidiary of
    Thermedics Inc.) and subsidiaries as of December 28, 1996, and December
    30, 1995, and the related consolidated statements of income,
    shareholders' investment, and cash flows for each of the three years in
    the period ended December 28, 1996. These consolidated financial
    statements are the responsibility of the Company's management. Our
    responsibility is to express an opinion on these consolidated 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 consolidated financial statements referred to
    above present fairly, in all material respects, the financial position of
    Thermo Voltek Corp. and subsidiaries as of December 28, 1996, and
    December 30, 1995, and the results of their operations and their cash
    flows for each of the three years in the period ended December 28, 1996,
    in conformity with generally accepted accounting principles.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

        Forward-looking statements, within the meaning of Section 21E of the
    Securities Exchange Act of 1934, are made throughout this Management's
    Discussion and Analysis of Financial Condition and Results of Operations.
    For this purpose, any statements contained herein that are not statements
    of historical fact may be deemed to be forward-looking statements.
    Without limiting the foregoing, the words "believes," "anticipates,"
    "plans," "expects," "seeks," "estimates," and similar expressions are
    intended to identify forward-looking statements. There are a number of
    important factors that could cause the results of the Company to differ
    materially from those indicated by such forward-looking statements,
    including those detailed immediately after this Management's Discussion
    and Analysis of Financial Conditions and Results of Operations under the
    caption "Forward-looking Statements."

    Overview

        The Company designs, manufactures, and markets electromagnetic
    compatibility (EMC) testing instruments, high-voltage power-conversion
    systems, and programmable power amplifiers. The Company's KeyTek
    Instrument (KeyTek) division manufactures instruments that test for
    immunity to pulsed electromagnetic interference (pulsed EMI). Through its
    Universal Voltronics division, the Company manufactures high-voltage
    power conversion systems that transform utility-supplied AC power into DC
    voltages and currents required by the user, while allowing precise
    control over the performance level desired for each application. The
    Company's Kalmus division manufactures radio frequency power amplifiers
    and systems used to test products for immunity to conducted and radiated
    radio frequency interference (RFI). Comtest Europe B.V. (Comtest)
    manufactures and distributes a range of EMC-related products, provides
    EMC consulting and systems-integration services, and manufactures
    specialized power supplies for telecommunications equipment. Acquired in
    July 1996, Pacific Power Source Corporation (Pacific Power) manufactures
    programmable power amplifiers that can be incorporated into EMC test
    equipment to assess tolerance to normal variances in the quality and
    quantity of AC voltage. 
        The Company's strategy is to expand through a combination of internal
    product development and the acquisition of new businesses and
    technologies. The Company acquired Pacific Power to provide additional
    depth to its line of EMC products and services. The Company plans to make
    additional acquisitions to expand the range of EMC products and services
    it can offer to its customers.
        Approximately 60% and 63% of the Company's revenues in 1996 and 1995,
    respectively, were derived from sales of products outside the U.S.,
    through export sales and sales by the Company's European operations.
    Although the Company seeks to charge its customers in the same currency
    as its operating costs, the Company's financial performance and
    competitive position can be affected by currency exchange rate
    fluctuations.

    Thermo Voltek Corp.                             1996 Financial Statements

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

    Results of Operations

    1996 Compared With 1995
        Revenues increased 34% to $48.5 million in 1996 from $36.3 million in
    1995, due to an increase in revenues at Comtest, the inclusion of $3.0
    million in revenues from the July 1996 acquisition of Pacific Power, and
    increased revenues at KeyTek and Kalmus. Revenues at Comtest increased
    primarily due to an increase in demand for electrostatic-discharge test
    equipment manufactured by its Verifier division, as well as an increase
    in revenues from a product line for testing immunity to RFI that was
    introduced in 1995. Increased revenues at KeyTek primarily resulted from
    greater demand for its EMC test equipment.  The Company anticipates that 
    sales of its EMC test products will slow in 1997, as many companies have 
    completed purchases necessary to come into compliance with IEC 801, the
    European Union directive on electromagnetic compatability. Revenues at 
    Kalmus, acquired in March 1995, increased $1.1 million due to the 
    inclusion of revenues for the full year in 1996 and $1.3 million primarily
    due to increased shipments resulting from the implementation of 
    manufacturing efficiencies.
        The gross profit margin increased to 50% in 1996 from 48% in 1995,
    primarily due to an increase in higher-margin domestic sales at KeyTek
    and an increase in the gross profit margin at Kalmus, primarily due to
    implementation of manufacturing efficiencies.
        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 31% in 1996 from 32% in 1995, primarily due to an
    increase in revenues. Research and development expenses as a percentage
    of revenues increased to 7.5% in 1996 from 6.5% in 1995, principally due
    to higher research and development expenses at Comtest and KeyTek.
        Interest income decreased to $1.8 million in 1996 from $2.1 million
    in 1995, primarily due to lower average invested balances. Interest
    expense decreased to $1.4 million in 1996 from $2.1 million in 1995,
    primarily due to conversions of the Company's subordinated convertible
    obligations during 1995 and 1996.
        The effective tax rate was 26% in 1996 and 21% in 1995. The effective
    tax rates were below the statutory federal income tax rate primarily due
    to the elimination of the tax valuation allowance that was no longer
    required (Note 6), offset in part by the impact of state income taxes.
    The effective tax rate increased in 1996 primarily due to a decrease in
    tax net operating loss carryforwards as a percentage of income before
    provision for income taxes. As of December 28, 1996, the Company has no
    further net operating loss carryforwards that will benefit future
    periods. Accordingly, the Company expects its effective tax rate in 1997
    to increase.

    1995 Compared With 1994
        Revenues increased 54% to $36.3 million in 1995 from $23.6 million in
    1994. The increase in revenues is primarily the result of the inclusion
    of $4.7 million in revenues from Kalmus, acquired in March 1995, an
    increase of $3.1 million in revenues from Comtest, and an increase of
    $2.5 million in revenues due to the inclusion of revenues for the full
    year of 1995 from Verifier, acquired in July 1994. The increase in
    revenues from Comtest resulted primarily from the introduction in 1995 of
    a new product line for testing immunity to RFI and, to a lesser extent,
    the favorable effects of currency translation due to a weaker U.S. dollar

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

    1995 Compared With 1994 (continued)
    in 1995. The balance of the increase in sales resulted from greater
    demand at KeyTek and, to a lesser extent, Universal Voltronics. 
        The gross profit margin decreased to 48% in 1995 from 49% in 1994,
    primarily due to higher European sales in 1995 in one of KeyTek's product
    lines, which have lower margins due to competitive pricing pressures and,
    to a lesser extent, higher costs associated with an upgraded product at
    KeyTek. These decreases were offset in part by the inclusion of
    higher-margin Verifier revenues.
        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 32% in 1995 from 34% in 1994, primarily due to
    lower costs as a percentage of revenues at KeyTek and Universal
    Voltronics as a result of higher sales volume in 1995, and lower selling,
    general, and administrative expenditures as a percentage of revenues at
    Kalmus. Research and development expenses as a percentage of revenues was
    relatively unchanged at 6.5% in 1995, compared with 6.3% in 1994.
        Interest income increased to $2.1 million in 1995 from $1.7 million
    in 1994, primarily due to higher prevailing interest rates in 1995.
    Interest expense was $2.1 million in 1995, compared with $2.2 million in
    1994. The decrease in interest expense resulting from the conversion of
    $9.1 million principal amount of the Company's subordinated convertible
    obligations during 1995 was substantially offset by the inclusion of
    interest expense associated with increased borrowings under Comtest's
    outstanding line of credit.
        The effective tax rate was 21% in 1995 and 25% in 1994. These rates
    were below the statutory federal income tax rate primarily due to the
    utilization of tax net operating loss carryforwards, offset in part by
    the impact of state income taxes. The decrease in the effective tax rate
    in 1995 was due to increased utilization of tax net operating loss
    carryforwards.

    Liquidity and Capital Resources

        Working capital was $40.9 million at December 28, 1996, compared with
    $41.8 million at December 30, 1995. Included in working capital are cash,
    cash equivalents, and available-for-sale investments of $27.9 million at
    December 28, 1996, compared with $34.7 million at December 30, 1995.
    During 1996, $0.5 million of cash was provided by operating activities.
    Cash flow from operations was offset by cash used to fund increases in
    certain current assets, including an increase in accounts receivable of
    $3.6 million, primarily due to an increase in revenues.
        During 1996, the Company's primary investing activities, excluding
    purchases, sales, and maturities of available-for-sale investments,
    included the acquisition of Pacific Power and capital expenditures. In
    July 1996, the Company acquired substantially all of the assets, subject
    to certain liabilities, of Pacific Power for approximately $6.3 million
    in cash, including the repayment of $0.8 million in debt. During 1996,
    the Company expended $2.0 million for purchases of property, plant, and
    equipment, and expects to make capital expenditures of approximately $2
    million during 1997.

                  Financial Condition and Results of Operations

    Liquidity and Capital Resources (continued)

        During 1996, financing activities provided $0.7 million in cash,
    including $0.5 million from an increase in notes payable.
        Although the Company expects to have positive cash flow from its
    existing operations, the Company anticipates it will require significant
    amounts of cash for the possible acquisition of complementary businesses
    and technologies. The Company expects that it will finance these
    acquisitions through a combination of internal funds, additional debt or
    equity financing, and/or short-term borrowings from Thermo Electron
    Corporation or Thermedics Inc., although there is no agreement with these
    companies to ensure that funds will be available on acceptable terms or
    at all. The Company believes that its existing resources are sufficient
    to meet the capital requirements of its existing operations for the
    foreseeable future.

                           Forward-looking Statements


        In connection with the "safe harbor" provisions of the Private
    Securities Litigation Reform Act of 1995, the Company wishes to caution
    readers that the following important factors, among others, in some cases
    have affected, and in the future could affect, the Company's actual
    results and could cause its actual results in 1997 and beyond to differ
    materially from those expressed in any forward-looking statements made
    by, or on behalf of, the Company.
        Rapid Technological Change. The market for EMC testing products and
    services is characterized by rapid technological change. No assurance can
    be given that the Company will be able to develop new and enhanced
    instruments that keep pace with technological developments and respond to
    the increasingly complex requirements of electronics manufacturers.
        Reliance on Electrical Standards. Demand for the Company's EMC
    testing products and services is driven to a large extent by mandatory
    government standards and voluntary industry standards relating to
    electromagnetic compatibility. In particular, demand for the Company's
    products results from efforts by manufacturers to comply with IEC 801, an
    EC directive that became effective on January 1, 1996. Although many
    manufacturers have not yet complied with IEC 801, as the number of
    noncomplying manufacturers is reduced over time, demand for the Company's
    products could be adversely affected. In addition, if new EMC standards
    requiring new testing capabilities are enacted less frequently or if EMC
    standards become less strict, demand for the Company's products could be
    adversely affected.
        Sole Source Suppliers. A number of the components of the Company's
    EMC testing products are supplied by single vendors. Although the Company
    has not experienced significant difficulty in obtaining adequate supplies
    from these vendors, and believes that it would be able to identify
    alternative suppliers if necessary, there can be no assurance that the
    unanticipated loss of a single vendor would not result in delays in
    shipments or in the introduction of new products.
        International Sales. International sales account for a significant
    portion of the Company's revenues. Sales to customers in certain foreign
    countries are subject to a number of risks, including the following:
    agreements may be difficult to enforce, and receivables difficult to
    collect, through a foreign country's legal system; foreign customers may
    have longer payment cycles; foreign countries could impose withholding
    taxes or otherwise tax the Company's foreign income, impose tariffs,
    embargoes, or exchange controls, or adopt other restrictions on foreign
    trade; and export licenses, if required, may be difficult to obtain. In
    addition, fluctuations in foreign currency exchange rates could have an
    adverse impact on international sales.
        Risks Associated With Acquisition Strategy. The Company's strategy
    includes the acquisition of businesses and technologies that complement
    or augment the Company's existing product lines. Promising acquisitions
    are difficult to identify and complete for a number of reasons, including
    competition among prospective buyers and the need for regulatory
    approval, including antitrust approvals. There can be no assurance that
    the Company will be able to complete future acquisitions or that the
    Company will be able to successfully integrate any acquired business. In
    order to finance such acquisitions, it may be necessary for the Company
    to raise additional funds through public or private financings. Any
