                   Notes to Consolidated Financial Statements


    1.  General

        The interim consolidated financial statements presented have been
    prepared by Thermo Voltek Corp. (the Company) without audit and, in the
    opinion of management, reflect all adjustments of a normal recurring
    nature necessary for a fair statement of the financial position at March
    29, 1997, the results of operations for the three-month periods ended
    March 29, 1997, and March 30, 1996, and the cash flows for the
    three-month periods ended March 29, 1997, and March 30, 1996. Interim
    results are not necessarily indicative of results for a full year.

        The consolidated balance sheet presented as of December 28, 1996, has
    been derived from the consolidated financial statements that have been
    audited by the Company's independent public accountants. The consolidated
    financial statements and notes are presented as permitted by Form 10-Q
    and do not contain certain information included in the annual financial
    statements and notes of the Company. The consolidated financial
    statements and notes included herein should be read in conjunction with
    the financial statements and notes included in the Company's Annual
    Report on Form 10-K, as amended, for the fiscal year ended December 28,
    1996, filed with the Securities and Exchange Commission.

    2.  Subsequent Event

        In April 1997, the Company acquired substantially all of the assets,
    subject to certain liabilities, of Milmega Ltd. for approximately $3.2
    million in cash, subject to a post-closing adjustment. Milmega primarily
    manufactures and markets microwave and radio frequency products and
    systems that are suitable for electromagnetic compatibility (EMC)
    testing, physics research, and communications, medical, and military
    applications. The Company will account for this acquisition using the
    purchase method of accounting.

             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

    Description of Business

        The Company designs, manufactures, and markets electromagnetic
    compatibility (EMC) testing instruments, high-voltage power-conversion
    systems, programmable power amplifiers, and radio frequency (RF) 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 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 RF power
    amplifiers and systems used to test products for immunity to conducted
    and radiated radio frequency interference (RFI) and in communications,
    medical, and research applications. 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
    power conversion equipment for use in a variety of commercial
    applications and 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 Milmega Ltd. in April 1997 (Note 2)
    and Pacific Power in July 1996.

        The Company sells its products on a worldwide basis. 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.

    Results of Operations

    First Quarter 1997 Compared With First Quarter 1996

        Revenues decreased 9% to $9.7 million in the first quarter of 1997
    from $10.6 million in the first quarter of 1996, primarily due to
    decreased revenues at Comtest and KeyTek, offset in part by the inclusion
    of $1.7 million in revenues from Pacific Power, acquired in July 1996.
    The decline in revenues at Comtest and KeyTek resulted primarily from
    lower demand for EMC test products and, to a lesser extent, a decline in
    the component-reliability market for electrostatic discharge test
    equipment, caused by a slowdown in capital expenditures by the
    semiconductor industry.

        The gross profit margin decreased to 44% in the first quarter of 1997
    from 49% in the first quarter of 1996, primarily due to the sale of
    lower-margin products at Comtest and the effect of the Company's decrease
    in revenues, offset in part by the effect of the inclusion of higher-
    margin revenues at Pacific Power.

                               THERMO VOLTEK CORP.

    First Quarter 1997 Compared With First Quarter 1996 (continued)

        Selling, general, and administrative expenses as a percentage of
    revenues increased to 42% in the first quarter of 1997 from 31% in the
    first quarter of 1996, primarily due to a decrease in revenues. Research
    and development expenses as a percentage of revenues increased to 8.7% in
    the first quarter of 1997 from 6.7% in the first quarter of 1996,
    primarily due to a decrease in revenues.

        In response to the decrease in revenues and operating income in the
    first quarter of 1997, the Company plans to undertake a restructuring in
    the second quarter of 1997 at certain business units, which will result
    in a charge to its results of operations. The Company expects to achieve
    lower operating costs following completion of the restructuring
    activities.

        Interest income decreased to $0.4 million in the first quarter of
    1997 from $0.5 million in the first quarter of 1996, primarily due to
    lower average invested balances. Interest expense decreased to $0.3
    million in the first quarter of 1997 from $0.4 million in the first
    quarter of 1996, primarily due to conversions of the Company's
    subordinated convertible obligations during 1996 and the first quarter of
    1997.

        The effective tax rates were 38% and 29% in the first quarter of 1997
    and 1996, respectively. The effective tax rate exceeded the statutory
    federal income tax rate in 1997 primarily due to the impact of state
    income taxes. The effective tax rate was below the statutory income tax
    rate in 1996 primarily due to utilization of net operating loss
    carryforwards, offset in part by the impact of state income taxes. As of
    December 28, 1996, the Company had no further net operating loss
    carryforwards.

    Liquidity and Capital Resources

        Consolidated working capital was $40.7 million at March 29, 1997,
    compared with $40.9 million at December 28, 1996. Included in working
    capital are cash, cash equivalents, and available-for-sale investments of
    $28.5 million at March 29, 1997, compared with $27.9 million at December
    28, 1996. During the first quarter of 1997, $0.3 million of cash was
    provided by operating activities. A decrease in accounts receivable of
    $1.5 million due to a decrease in revenues was offset in part by cash
    used to decrease accounts payable and other current liabilities by $0.8
    million.

        Excluding available-for-sale investments activity, the Company's
    investing activities in the first quarter of 1997 consisted primarily of
    $0.3 million of expenditures for purchases of property, plant, and
    equipment. The Company expects to make capital expenditures of
    approximately $1.5 million during the remainder of 1997. Financing
    activities provided $0.7 million in cash in the first quarter of 1997,
    primarily related to an increase in notes payable.

    Liquidity and Capital Resources (continued)

        In April 1997, the Company acquired substantially all of the assets,
    subject to certain liabilities, of Milmega Ltd. for approximately $3.2
    million in cash, subject to a post-closing adjustment (Note 2).

        In April 1997, the Company's Board of Directors authorized the
    repurchase, through April 17, 1998, of up to $10.0 million of Company
    common stock. Any such purchases would be funded from working capital.

        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.
