                               ACTERNA CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.    FORMATION, BACKGROUND AND RECLASSIFICATION OF FINANCIAL STATEMENT
      PRESENTATION

      Acterna Corporation was formed in 1959 and is a global communications
      equipment company focused on network technology solutions. The Company's
      operations are conducted by wholly owned subsidiaries located principally
      in the United States of America and Europe with other operations,
      primarily sales offices, located in Asia and Latin America. The Company is
      managed in two business segments: communications test and industrial
      computing and communications. The Company also has other subsidiaries
      that, in the aggregate, are not reportable as a segment.

      The Company previously reported the industrial computing and
      communications segment as discontinued operations. This segment is
      comprised of two subsidiaries: ICS Advent and Itronix Corporation. In
      October 2001, the Company divested its ICS Advent subsidiary (see Note M.
      Sale of ICS Advent and Other Subsidiary), but decided to retain Itronix
      based on current market conditions. The decision to retain Itronix
      required the Company to make certain reclassifications to its Statements
      of Operations and Balance Sheets for all periods presented. The Statements
      of Operations were reclassified to include the results of operations of
      ICS Advent and Itronix. The Balance Sheets as of December 31, 2001 and
      March 31, 2001 include the assets and liabilities of Itronix. The Balance
      Sheet at March 31, 2001 reflects the net assets of ICS Advent classified
      as net assets held for sale. The Statement of Cash Flows was not
      reclassified as these statements were not previously presented on a
      discontinued basis.

      The communications test business develops, manufactures and markets
      instruments, systems, software and services used to test, deploy, manage
      and optimize communications networks, equipment and services.

      The industrial computing and communications segment provides computer
      products to the ruggedized computer market. ICS Advent sold computer
      products and systems designed to withstand excessive temperatures, dust,
      moisture and vibration in harsh operating environments. Itronix sells
      ruggedized portable communications and computing devices used by field
      service workers.

      In addition the Company also operates two subsidiaries, AIRSHOW, Inc., and
      da Vinci Systems. AIRSHOW is the leading provider of systems that deliver
      real-time news, information and flight data to aircraft passengers. da
      Vinci manufactures systems that correct or enhance the accuracy of color
      during the process of transferring film-based images to videotape.

      The Company operates on a fiscal year ended March 31 in the calendar year
      indicated (e.g., references to fiscal 2002 are references to the Company's
      fiscal year which began April 1, 2001 and will end March 31, 2002). Unless
      the context otherwise requires, the "Company" or "Acterna" refers to
      Acterna Corporation and its subsidiaries.

B.    RECENT DEVELOPMENTS AND LIQUIDITY

      The current global economic downturn has further impacted a previously
      existing downturn in the Company's communications test segment and in its
      other


                                       5

<PAGE>

      businesses. The Company continues to experience diminished product demand,
      excess manufacturing capacity and erosion of average selling prices.

      In response to the decline in product demand, the Company continues to
      implement cost reduction programs aimed at aligning its ongoing operating
      costs with its expected revenues. In the third quarter of fiscal 2002, the
      Company's headcount was further reduced to 5,200 (down from 6,380 at the
      beginning of fiscal 2002), and the corporate headquarters was relocated
      from Burlington, Massachusetts to Germantown, Maryland. Given the severity
      of current market conditions, however, the Company cannot make any
      assurance that these cost reduction programs will actually align the
      Company's operating expenses and revenues, be sufficient to avoid
      operating losses, or that additional cost reduction programs will not be
      necessary in the future.

      On December 27, 2001 the Company amended its senior secured credit
      facility. (See Note J. Senior Secured Credit Agreement Amendment.) The
      continuing effectiveness of this amendment was conditioned upon the
      Company raising new financing of $75 million within a specified time. This
      was completed on January 15, 2002. (See Note Q. Subsequent Event -
      Issuance and Sale of $75 Million 12% Senior Secured Convertible Notes.) As
      of December 31, 2001, the Company was in compliance with the covenants
      under its senior secured credit facility as amended.

      The Company's cash requirements for debt service and ongoing operations
      are substantial. While there can be no assurance that the Company will
      have sufficient funds or available funds to meet its cash needs over the
      next twelve months, as a result of the amendment of the senior secured
      credit agreement and the issuance at par of $75 million of 12% Senior
      Secured Convertible Notes in January 2002, the Company believes that funds
      generated by ongoing operations and funds available under its senior
      secured credit facility will be sufficient to meet its cash needs over the
      next twelve-month period.

      These and other risks associated with the Company's business are described
      in the Company's Securities and Exchange Commission reports, including the
      Company's Annual Report on Form 10-K for the fiscal year ended March 31,
      2001.

C.    CONSOLIDATED FINANCIAL STATEMENTS

      In the opinion of management, the unaudited consolidated balance sheet at
      December 31, 2001, and the unaudited consolidated statements of operations
      and unaudited consolidated statements of cash flows for the interim
      periods ended December 31, 2001 and 2000 include all adjustments
      (consisting only of normal recurring adjustments) necessary to present
      fairly these financial statements.

      Certain information and footnote disclosures normally included in
      financial statements prepared in accordance with generally accepted
      accounting principles have been omitted. The year-end balance sheet data
      was derived from audited financial statements, but does not include
      disclosures required by generally accepted accounting principles. These
      statements should be read in conjunction with the Company's most recent
      Form 10-K as of March 31, 2001.

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make certain
      estimates and assumptions that affect the reported amount of assets and
      liabilities and disclosure of contingent assets and liabilities at the
      date of the financial statements and the reported amounts of revenues and
      expenses during the reported period. Significant estimates in these
      financial statements include allowances for accounts receivable, net
      realizable value of inventories, purchased


                                       6

<PAGE>

      incomplete technology, warranty accruals and tax valuation reserves.
      Actual results could differ from those estimates.

D.    NEW PRONOUNCEMENTS

      In July 2001, the Financial Accounting Standards Board issued Statement of
      Financial Accounting Standards No. 141, "Business Combinations" ("FAS
      141") and No. 142, "Goodwill and Other Intangible Assets" ("FAS 142"). FAS
      No. 141 requires that all business combinations be accounted for under the
      purchase method only and that certain acquired intangible assets in a
      business combination be recognized as assets apart from goodwill. FAS No.
      142 requires that ratable amortization of goodwill be replaced with
      periodic tests of the goodwill's impairment and that intangible assets
      other than goodwill be amortized over their useful lives. FAS No. 141 is
      effective for all business combinations initiated after June 30, 2001 and
      for all business combinations accounted for by the purchase method for
      which the date of acquisition is before June 30, 2001. The provisions of
      FAS No. 142 will be effective for fiscal years beginning after December
      15, 2001; however, the Company elected to early adopt the provisions
      effective April 1, 2001.

      In October 2001, the Financial Accounting Standards Board ("FASB") issued
      Statement of Financial Accounting Standards No. 144, "Accounting for the
      Impairment or Disposal of Long-Lived Assets" ("FAS 144"). FAS 144
      supercedes FASB Statement No. 121, "Accounting for the Impairment of
      Long-Lived Assets and for Long-Lived Assets to be Disposed of". FAS 144
      applies to all long-lived assets (including discontinued operations) and
      consequently amends Accounting Principles Board Opinion No. 30, "Reporting
      Results of Operations- Reporting the Effects of Disposal of a Segment of a
      Business". FAS 144 is effective for financial statements issued for fiscal
      years beginning after December 15, 2001, and will thus be adopted by the
      Company, as required, on April 1, 2002. Management is currently
      determining what effect, if any, FAS 144 will have on its financial
      position and results of operations.

E.    INCOME TAXES

      During the quarter ended September 30, 2001 the Company recorded a
      valuation allowance of approximately $71 million against all of its U.S.
      net deferred tax assets. Statement of Financial Accounting Standards No.
      109 requires a valuation allowance to be recorded against deferred tax
      assets when it is more likely than not that some or all of the deferred
      tax assets will not be realized. As a result of the downturn in the
      telecommunications test equipment sector, the Company has incurred
      significant and previously unanticipated financial accounting and taxable
      losses in the U.S. for the first half of the current fiscal year, and the
      current outlook indicates that significant uncertainty will continue for
      the remainder of this fiscal year and into the next fiscal year. These
      cumulative losses, together with the Company's prior fiscal financial
      accounting and taxable losses in the U.S., resulted in management's
      decision that it is more likely than not that all of its U.S. deferred tax
      assets will not be realized.

      The Company will continue to provide a valuation allowance against
      primarily all of its U.S. net deferred tax assets until it returns to an
      appropriate level of financial accounting and taxable income in the U.S.
      The ultimate realization of these deferred tax assets depends upon the
      Company's ability to generate sufficient future taxable income in the U.S.
      If the Company is successful in generating sufficient future taxable
      income in the U.S., the Company will reduce the valuation allowance
      through a reduction in income tax expense in the future.

      The goodwill adjustments in the communications test reporting unit
      resulted primarily from final adjustments to the purchase price allocation
      for the Wavetek Wandel Goltermann merger (See Note L. Acquisitions) and to
      the deferred tax adjustment in respect to reclassifying certain intangible
      assets as goodwill on adoption of FAS 142. The goodwill adjustment for the
      Itronix reporting unit is related to the disposition of a subsidiary of
      Itronix during the second quarter of fiscal 2002. The goodwill adjustment
      for da Vinci relates to the goodwill impairment as a result of the closure
      of a subsidiary of da Vinci Systems, Inc. during the third quarter of
      fiscal 2002.

      The Company completed its transitional impairment test of goodwill during
      the quarter ended September 30, 2001 for all reporting units required
      under FAS 142 as of March 31, 2001 and determined that goodwill was not
      impaired. The impairment testing was based on discounted cash flow
      analyses of expectations of future earnings for each of the reporting
      units over the remaining estimated lives of the separately identifiable
      intangible assets. The Company's annual impairment test will be performed
      as of March 31, 2002. If the Company's expectations as to future results
      are diminished significantly, goodwill may be impaired and any resulting
      noncash impairment charge may have an adverse effect on results of
      operations.

I.    DISCONTINUED OPERATIONS

      In May 2000, the Board of Directors approved a plan to divest the
      industrial computing and communications segment, which consists of ICS
      Advent and Itronix Corporation subsidiaries. In October 2001, the Company
      divested its ICS Advent subsidiary (see Note M. Sale of ICS Advent and
      Other Subsidiary), but decided to retain Itronix based on current market
      conditions. The decision to retain Itronix required the Company to make
      certain reclassifications to its Statements of Operations and Balance
      Sheets for all periods presented. Management had previously expected that
      proceeds on disposal of both businesses comprising the segment would
      exceed net assets, including operating losses incurred subsequent to May
      2000, and accordingly these operating losses were deferred.

      The net operating losses for ICS Advent and Itronix included in continuing
      operations for the three and nine months ended December 31, 2000 were
      offset by an equal net income amount presented on the discontinued
      operations line within the Statement of Operations. Therefore, the net
      loss in total for the Company as previously reported for these periods did
      not change. The charge reported as discontinued operations for the nine
      months ended December 31, 2001 represents the cumulative net operating
      losses previously deferred from April 1, 2000 to June 30, 2001 for ICS
      Advent and Itronix.

      The Balance Sheets as of December 31, 2001 and March 31, 2001 include the
      assets and liabilities of Itronix. The Balance Sheet at March 31, 2001
      reflects the net assets of ICS Advent classified as net assets held for
      sale. The Statement of Cash Flows was not reclassified as these statements
      were not previously presented on a discontinued basis.

J.    SENIOR SECURED CREDIT AGREEMENT AMENDMENT

      On December 27, 2001, the Company entered into an amendment to the credit
      agreement governing its senior secured credit facility. Under the
      amendment, the lenders under the credit agreement, among other things,
      agreed to waive the minimum interest coverage and maximum leverage
      covenants of the Company under the credit agreement through June 30, 2003
      and consented to the issuance and sale of the 12% Senior Secured
      Convertible Notes Due 2007 (See Note Q. Subsequent Event - Issuance and
      Sale of $75 Million 12% Senior Secured Convertible Notes.). Under the
      amendment, the Company also became subject to certain additional covenants
      and restrictions, including, without limitation, new minimum liquidity and
      EBITDA requirements and additional restrictions on the Company's ability
      to make capital expenditures, incur and guarantee debt, make investments,
      optionally prepay the 9.75% Senior Subordinated Notes Due 2008 and dispose
      of assets. The amendment also, among other things, adds additional
      prepayment requirements for certain transactions, establishes additional
      guarantees and pledges of collateral and increases the interest rates on
      loans under the senior secured credit facility by 0.75%. On June 30, 2003,
      the Company will again become subject to its minimum interest coverage and
      maximum leverage covenants under the credit agreement. The Company can
      make no assurance that it will be in compliance with these covenants upon
      such reversion.

      The Company incurred a $2.9 million fee payable to the lenders under its
      senior secured credit facility in connection with the consummation of the
      amendment and has been capitalized as deferred debt issuance costs that
      will be amortized over the remaining life of the senior secured credit
      agreement.

K.    RESTRUCTURING

      Due to the downturn in the Company's communications test segment and its
      other businesses, the Company announced on August 1, 2001 a comprehensive
      cost reduction program that includes the reduction of (1) approximately
      400 jobs worldwide; (2) outside contractors and consultants; (3) operating
      expenses; and (4) manufacturing costs through procurement programs to
      lower materials costs. As a result of these measures, the Company recorded
      a charge of $8 million during the quarter ended September 30, 2001
      relating primarily to severance and terminated 328 employees and paid
      approximately $1.9 million in severance and other related costs.

      In October 2001, the Company announced an expanded cost reduction plan
      that included (1) a reduction of 500 additional positions excluding the
      employees of the sold ICS Advent subsidiary; (2) consolidating certain of
      its development and marketing offices; (3) instituting a reduced workweek
      at selected manufacturing locations; and (4) reducing capital
      expenditures. In addition, the Company announced the relocation of its
      Burlington, Massachusetts corporate headquarters to Germantown, Maryland.
      The Company incurred a restructuring charge of $9.3 million in connection
      with this plan in the quarter ended December 31, 2001 and terminated 394
      employees under this plan.

      The following table summarizes the restructuring expenses and payments
      incurred during the three and nine months ended December 31, 2001:

M.    SALE OF ICS ADVENT AND OTHER SUBSIDIARY

      On October 31, 2001, the Company sold its ICS Advent subsidiary for $23
      million in cash proceeds. The Company wrote down the net assets of ICS
      Advent at September 30, 2001, to the cash to be received less expenses
      related to the sale, which resulted in an impairment charge of $15 million
      in the Statement of Operations in the quarter ended September 30, 2001.

      In addition, the Company recorded a charge of $2.9 million relating to the
      disposition of a subsidiary of Itronix Corporation during the second
      quarter of fiscal 2002.

N.    EXTRAORDINARY ITEM

      In connection with the WWG Merger in May 2000, the Company recorded an
      extraordinary charge of $10.7 million (net of an income tax benefit of
      $6.6 million), of which $7.3 million (pretax) related to a premium paid by
      the Company to WWG's former bondholders to repurchase WWG's senior
      subordinated debt outstanding prior to the WWG Merger. In addition, the
      Company booked a charge of $10.0 million (pretax) for the unamortized
      deferred debt issuance costs which originated at the time of the
      recapitalization of the Company in May of 1998.

      The Company did not have any common stock equivalents for the three and
      nine month period ended December 31, 2001. For the three and nine months
      ending December 31, 2000, the Company excluded from its diluted weighted
      average shares outstanding the effect of the weighted average common stock
      equivalents of 12.7 million and 14.5 million, respectively, as the Company
      incurred a net loss. The inclusion of the common stock equivalents has
      been excluded from the calculation of diluted weighted average shares
      outstanding as inclusion would have an antidilutive effect on net loss per
      common share.

Q.    SUBSEQUENT EVENT - ISSUANCE AND SALE OF $75 MILLION 12% SENIOR SECURED
      CONVERTIBLE NOTES

      On January 15, 2002, Acterna LLC, a wholly-owned subsidiary of the
      Company, issued and sold at par $75 million aggregate principal amount of
      12% Senior Secured Convertible Notes Due 2007 (the "Notes") to Clayton,
      Dubilier & Rice Fund VI Limited Partnership. The Company used the proceeds
      of the issuance and sale of the Notes (net of fees and expenses) to repay
      a portion of its indebtedness under its revolving credit facility. The
      amounts repaid remain available to be reborrowed by the Company.

      Interest on the Notes is payable semi-annually in arrears on each March
      31st and September 30th, with interest payments commencing on March 31,
      2002. At the option of Acterna LLC, interest is payable in cash or in-kind
      by the issuance of additional Notes. Due to limitations imposed by the
      senior secured credit facility, Acterna LLC expects to pay interest on the
      Notes in-kind by issuing additional Notes. The Notes are secured by a
      second lien on all of the assets of the Company and its subsidiaries that
      secure the senior secured credit facility, and are guaranteed by the
      Company and its domestic subsidiaries.

      Subject to prior approval of the Company's stockholders (as described
      below), at the option of Clayton, Dubilier & Rice Fund VI Limited
      Partnership (or any subsequent holder of Notes), at any time prior to
      December 31, 2007, the maturity date of the Notes, the Notes may be
      converted into newly-issued shares of common stock of the Company at a
      conversion price of $3.00 per share, subject to customary antidilution
      adjustments. On the date of issuance, the conversion price of the Notes
      exceeded the public market price per share of common stock of the Company.
      If in the future any Note is issued with a conversion price that is less
      than the public market price on January 15, 2002 (the date of original
      issuance) as a result of an anti-dilution adjustment of the conversion
      price, then the Company would be required to take a charge to its results
      of operations to reflect the discount of the adjusted conversion price to
      the market price of the common stock on the date of original issuance.

      Acterna LLC may redeem the Notes, in whole or in part, and without penalty
      or premium, at any time prior to the maturity date. In addition, Acterna
      LLC is required to offer to repurchase the Notes upon a change of control
      and upon the disposition of certain assets. If any Note is redeemed,
      repurchased or repaid for any reason prior to the maturity date, the
      holder will be entitled to receive from the Company a warrant to purchase
      a number of newly-issued shares of common stock of the Company equal to
      the number of shares of common stock that such Note was convertible into
      immediately prior to its redemption, repurchase or repayment. The exercise
      price of such warrant will be the conversion price in effect immediately
      prior to such warrant's issuance, subject to customary antidilution
      adjustments. Subject to the approval of the Company's


                                       14

<PAGE>

      stockholders (as described below), warrants will be exerciseable upon
      issuance and will expire on the maturity date of the Notes. The Company is
      required to classify the contingently issuable warrants as liabilities.
      Because the warrants are only issuable upon redemption, repurchase or
      repayment prior to maturity, which requires the consent of the lenders
      under the Company's senior secured credit facility, the Company has valued
      the warrants at zero as of the date of issuance. The fair value of the
      warrants upon issuance will be recorded as a charge to operations.

      In order to comply with the rules of the Nasdaq National Market, where the
      common stock of the Company is listed, the terms of the Notes provide,
      and, if issued, the terms of the warrants will provide, that no Note or
      warrant may be converted or exercised, as the case may be, until the
      stockholders of the Company have approved the issuance of the shares of
      common stock upon such conversion or exercise. The Company expects to
      obtain such approval by obtaining the written consent of its stockholders.
      Without giving effect to the issuance and sale of the Notes, Clayton,
      Dubilier & Rice Fund V Limited Partnership and Clayton, Dubilier & Rice
      Fund VI Limited Partnership collectively own approximately 80% of the
      outstanding common stock of the Company. Each intends to vote its shares
      to approve the issuance of the shares of common stock upon conversion of
      the Notes or exercise of the warrants, thereby assuring that the Company
      will receive the stockholder approval necessary to comply with the Nasdaq
      rules.

      The Company incurred a $2.2 million fee payable to Clayton, Dubilier &
      Rice, Inc. in connection with the issuance and sale of the Notes.

R.    SUPPLEMENTAL CONDENSED CONSOLIDATING STATEMENTS OF ACTERNA CORPORATION AND
      ACTERNA LLC

      In connection with the Company's recapitalization and related
      transactions, Acterna LLC became the primary obligor with respect to
      substantially all of the indebtedness of Acterna Corporation, including
      the 9 3/4% Senior Subordinated Notes due 2008 (the "Senior Subordinated
      Notes").

      Acterna Corporation has fully and unconditionally guaranteed the Senior
      Subordinated Notes. Acterna Corporation, however, is a holding company
      with no independent operations and no significant assets other than its
      membership interest in Acterna LLC. Certain other subsidiaries of the
      Company are not guarantors of the Senior Subordinated Notes. The condensed
      consolidating financial statements presented herein include the statement
      of operations, balance sheets, and statements of cash flows without
      additional disclosure as the Company has determined that the additional
      disclosure is not material to investors.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

This Form 10-Q contains forward-looking statements that involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, product demand and market
acceptance risks, the effect of economic conditions, the effect of competitive
products and pricing, product development, commercialization and technological
difficulties, capacity and supply constraints or difficulties, availability of
capital resources, general business and economic conditions, the effect of the
Company's accounting policies, and other risks detailed in the Company's most
recent Form 10-K as of March 31, 2001 and below.

OVERVIEW

The Company is managed in two business segments: communications test and
industrial computing and communications. The Company also has other subsidiaries
that, in the aggregate, are not reportable as a segment.

The current global economic downturn has further impacted a previously existing
downturn in the Company's communications test segment as well as its other
businesses. As in past downturns, the Company continues to experience diminished
product demand, excess manufacturing capacity and erosion of average selling
prices. In the third quarter of the current fiscal year, the Company's bookings
increased to approximately $223.8 million from approximately $201.7 million in
the second quarter but down significantly from approximately $369.6 million in
the third quarter of last year (excluding bookings related to ICS Advent). At
present, the Company cannot predict the duration or severity of this downturn,
but based on the historical correlation between the Company's bookings and its
revenue, the Company expects fourth quarter revenue in its communications test
segment to be down substantially as compared with the same period last year.

The Company continues to implement cost reduction programs aimed at aligning its
ongoing operating costs with its expected revenues. In the third quarter of
fiscal 2002, the Company's headcount was further reduced to 5,200 (down from
6,380 at the beginning of fiscal 2002), and the corporate headquarters was
relocated from Burlington, Massachusetts to Germantown, Maryland. Given the
severity of current market conditions, however, the Company cannot make any
assurance that these cost reduction programs will actually align the Company's
operating expenses and revenues, be sufficient to avoid operating losses, or
that additional cost reduction programs will not be necessary in the future.

On August 1, 2001 the Company announced a comprehensive cost reduction program
that includes a reduction of: (1) approximately 400 jobs worldwide; (2) outside
contractors and consultants; (3) operating expenses; and (4) manufacturing costs
through procurement programs to lower materials costs. The Company expects these
steps to result in annualized cost savings in excess of $50 million. As a result
of these measures, the Company terminated 328 employees and recorded a charge of
$8 million relating primarily to severance in the second quarter of fiscal 2002.

In October 2001, the Company announced an expanded cost reduction plan which
included (1) a reduction of 500 additional positions excluding the employees of
the sold ICS Advent subsidiary; (2) consolidating certain of its development and


                                       22

<PAGE>

marketing offices; (3) instituting a reduced workweek at selected manufacturing
locations; (4) reducing capital expenditures, and (5) the relocation of its
corporate headquarters. The Company incurred a restructuring charge of $9.3
million for this plan.

During the nine months ended December 31, 2001, the Company paid approximately
$7.5 million in severance and other related costs. At December 31, 2001
approximately $9.8 million was left to be paid for this restructuring; the
Company anticipates that this amount will be paid primarily during the fourth
quarter of fiscal 2002. (See Note K. Restructuring.)

The Company previously reported the industrial computing and communications
segment as discontinued operations. This segment is comprised of two
subsidiaries: ICS Advent and Itronix Corporation. In October 2001, the Company
divested its ICS Advent subsidiary and decided to retain Itronix based on
current market conditions. The decision to retain Itronix required the Company
to make certain reclassifications to its Statements of Operations and Balance
Sheets for all periods presented. The Statements of Operations were reclassified
to include the results of operations of ICS Advent and Itronix. The balance
sheet reflects the assets and liabilities of Itronix, and the net assets of ICS
Advent are classified as net assets held for sale on the March 31, 2001 balance
sheet. On October 31, 2001, the Company sold its ICS Advent subsidiary for $23
million in cash. The Company recorded an impairment charge of $15 million in the
Statement of Operations for this transaction during the quarter ended September
30, 2001.

In July 2001, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards Number 141, ("FAS 141"), "Business Combinations"
and Number 142 ("FAS 142"), "Goodwill and Other Intangible Assets". FAS Number
141 requires that all business combinations be accounted for under the purchase
method only and that certain acquired intangible assets in a business
combination be recognized as assets apart from goodwill. FAS Number 142 requires
that ratable amortization of goodwill be replaced with periodic tests of the
goodwill's impairment and that intangible assets other than goodwill be
amortized over their useful lives. FAS Number 141 is effective for all business
combinations initiated after June 30, 2001 and for all business combinations
accounted for by the purchase method for which the date of acquisition is before
June 30, 2001. The provisions of FAS Number 142 will be effective for fiscal
years beginning after December 15, 2001; however, the Company elected to early
adopt the provisions effective April 1, 2001.

RESULTS OF OPERATIONS

For the Three Months Ended December 31, 2001 as Compared to Three Months Ended
December 31, 2000 on a Consolidated Basis

Net sales. For the three months ended December 31, 2001, consolidated net sales
decreased $121.2 million to $248.8 million as compared to $370 million for the
three months ended December 31, 2000. The decrease is primarily attributable to
reduced demand for the Company's communications tests products partially offset
by an increase in sales at Itronix.

Gross profit. Consolidated gross profit decreased $102.6 million to $116.5
million or 46.8% of consolidated net sales for the three months ended December
31, 2001 as compared to $219.1 million or 59.2% of consolidated net sales for
the three months ended December 31, 2000. The decrease in gross profit is in
part due to a charge of $15 million for inventory adjustments and other reserves
recorded during the third quarter of fiscal 2002 within the communications test
segment in response to the reduced forecasted demand due to the continuing
economic downturn. Excluding


                                       23

<PAGE>

the impact of the $15 million charge, gross profit was $131.5 million or 53% of
consolidated net sales. The reduction in gross profit is also a result of
shipping fewer optical transport products, which carry a higher gross profit
than other communications test products.

Operating expenses. Operating expenses consist of selling, general and
administrative expense; product development expense; goodwill impairment;
restructuring; and amortization of intangibles. Total operating expenses were
$166.6 million or 66.9% of consolidated net sales for the three months ended
December 31, 2001, as compared to $218.4 million or 59.0% of consolidated net
sales for the three months ended December 31, 2000. Excluding the impact of the
$3.9 million goodwill impairment charge and the $9.3 million restructuring
charge within the third quarter of fiscal 2002, total operating expenses were
$153.3 million or 61.6% of consolidated net sales for the three months ended
December 31, 2001. The decrease in operating expenses during the current quarter
is in part a result of restructuring and reduced employee expenses as described
above. The decrease is also attributable to the Company's early adoption of FAS
142 in the first quarter of fiscal 2002, which eliminated the amortization of
goodwill expense of approximately $27.3.

Included in both cost of sales ($0.3 million and $2.2 million) and operating
expenses ($4.6 million and $4.4 million) (for the three months ending December
31, 2001 and 2000, respectively,) is the amortization of unearned compensation
which relates to the issuance of non-qualified stock options to employees and
non-employee directors at a grant price lower than fair market value (defined as
the closing price on the open market at the date of issuance). The Company
discontinued the practice of issuing stock options at grant prices lower than
fair-market value during fiscal 2001. Therefore, the Company has not incurred
any additional charges for unearned compensation during fiscal 2002.

Selling, general and administrative expense was $105.2 million or 42.3% of
consolidated sales for the three months ended December 31, 2001, as compared to
$138.8 million or 37.5% of consolidated net sales for the three months ended
December 31, 2000. The decrease in these expenses is a result of the Company's
restructuring efforts to reduce operating costs of the business as well as a
result of the sale of ICS Advent. The Company has reduced its headcount by 710
employees since the end of the second quarter of fiscal 2002 of which 430 were
due to the restructuring and 280 were due to the sale of ICS Advent. The
increase as a percentage of sales is due to the reduction in sales caused by the
continuing economic downturn.

Product development expense was $38.1 million or 15.3% of consolidated net sales
for the three months ended December 31, 2001 as compared to $44.7 million or
12.1% of consolidated sales for the same period a year ago.

The Company recorded a charge of $3.9 million during the third quarter of fiscal
2002 related to goodwill impairment as a result of the closure of a subsidiary
of da Vinci Systems, Inc.

During the quarter, the Company incurred a charge of $9.3 million related
to the additional restructuring of the business. (See Note K. Restructuring).
This charge is primarily related to severance and other related costs.

Amortization of intangibles was $9.9 million for the three months ended December
31, 2001, as compared to $34.9 million for the amortization of intangibles and
goodwill in the same period a year ago. The decrease was primarily attributable
to the Company's early adoption of FAS 142 in the first quarter of fiscal 2002,
which eliminates the amortization of goodwill.


                                       24

<PAGE>

Interest. Interest expense, net of interest income, was $22.6 million for the
three months ended December 31, 2001 as compared to $27.1 million for the same
period a year ago. The decrease in interest expense was primarily attributable
to lower interest rates on borrowings during the third quarter of fiscal 2002 as
compared to the same period last year.

Taxes. During the third quarter of fiscal 2002 the Company recorded a tax
provision of $425 thousand. This represents a provision for taxes on earnings in
tax jurisdictions where the Company is profitable. The Company did not record a
tax benefit for losses incurred in the tax jurisdictions where the benefit of
the loss may not be realized. (See Note E. Income Taxes.)

Nine Months Ended December 31, 2001 as Compared to Nine Months Ended December
31, 2000 on a Consolidated Basis

Net sales. For the nine months ended December 31, 2001, consolidated net sales
decreased $52.8 million or 5.4% to $920.2 million as compared to $973.0 million
for the nine months ended December 31, 2000. The decrease in net sales is
primarily a result of a reduction in net sales of optical transport products
within the communications test segment. The Company also derived lower revenues
from Airshow and daVinci, but higher revenues at Itronix, as compared to the
same period last year.

Gross profit. Consolidated gross profit decreased $40.0 million to $489.7
million or 53.2% of consolidated net sales for the nine months ended December
31, 2001 as compared to $529.7 million or 54.4% of consolidated net sales for
the nine months ended December 31, 2000. Excluding the $35.8 million included in
cost of sales for the amortization of the inventory step-up from the
acquisitions of WWG and Cheetah during the same period last year, consolidated
gross profit was 58.1% of consolidated net sales. The decrease in gross profit
was primarily attributable to the erosion of gross margins as the Company
experienced pressure from its customers to reduce selling prices and a shift in
product mix toward the Company's lower-margin products.

Operating expenses. Operating expenses consist of selling, general and
administrative expense; product development expense; impairment of assets;
recapitalization and other related costs; restructuring; purchased incomplete
technology; and amortization of intangibles. Total operating expenses were
$547.9 million or 59.5% of consolidated net sales for the nine months ended
December 31, 2001, as compared to $620.1 million or 63.7% of consolidated net
sales for the nine months ended December 31, 2000. Excluding the impact of $21.9
million of asset impairment charges and $17.2 million of restructuring charges
in the first nine months of fiscal 2002, and a $56 million writeoff of purchased
incomplete technology and $9.2 million of recapitalization and other costs
(related to the departure of an executive of the Company during fiscal 2000)
during the first nine months of fiscal 2001, total operating expenses were
$508.8 million or 55.3% of consolidated net sales and $554.9 million or 57.0% of
consolidated net sales for the nine months ended December 31, 2001 and 2000,
respectively.

Included in both cost of sales ($1.1 million and $5.0 million) and operating
expenses ($15.9 million and $10.2 million) (for the nine months ending December
31, 2001 and 2000, respectively), is the amortization of unearned compensation
which relates to the issuance of non-qualified stock options to employees and
non-employee directors at a grant price lower than fair market value (defined as
the closing price on the open market at the date of issuance). The Company
discontinued the practice of issuing stock options at grant prices lower than
fair-market value during fiscal 2001.


                                       25

<PAGE>

Selling, general and administrative expense was $352.3 million or 38.3% of
consolidated net sales for the nine months ended December 31, 2001 as compared
to $351.9 million or 36.2% of consolidated net sales for the nine months ended
December 31, 2000.

Product development expense was $124.4 million or 13.5% of consolidated net
sales for the nine months ended December 31, 2001 as compared to $118.8 million
or 12.2% of consolidated sales for the same period a year ago.

The Company recorded a charge of $3.9 million during the third quarter of fiscal
2002 related to goodwill impairment as a result of the closure of a subsidiary
of da Vinci Systems, Inc.

During the nine months ended December 31, 2001, the Company incurred a charge of
$17.2 million related to the restructuring of the business. (See Note K.
Restructuring). This charge is primarily related to severance and other related
costs.

The Company wrote down the net assets of ICS Advent at September 30, 2001 to the
cash to be received upon the sale of ICS Advent less transaction-related
expenses, which resulted in an impairment charge of $15 million. ICS Advent was
sold on October 31, 2001. In addition, the Company recorded a charge of $2.9
million relating to the disposition of a subsidiary of Itronix Corporation.

Amortization of intangibles was $32.1 million for the nine months ended December
31, 2001, as compared to $84.2 million for the amortization of intangibles and
goodwill in the same period a year ago. The decrease was attributable to the
Company's early adoption of FAS 142 in the first quarter of fiscal 2002, which
eliminates the amortization of goodwill as well as only approximately one month
of goodwill amortization related to the WWG Merger during the first three months
of fiscal 2001.

Interest. Interest expense, net of interest income, was $72.1 million for the
nine months ended December 31, 2001 as compared to $71.2 million for the same
period a year ago.

Taxes. For the nine months ended December 31, 2001, the effective tax rate was
not meaningful due to the provision of a $71 million valuation allowance against
the Company's U.S. net deferred tax assets that was recorded in the second
quarter ended September 30, 2001. (See Note E. Income Taxes.)

Extraordinary item. In connection with the WWG Merger, the Company recorded an
extraordinary charge of approximately $10.7 million (net of an income tax
benefit of $6.6 million), of which $7.3 million (pretax) related to a premium
paid by the Company to WWG's former bondholders for the repurchase of WWG's
senior subordinated debt outstanding prior to the WWG Merger. In addition, the
Company booked a charge of $10.0 million (pretax) for the unamortized deferred
debt issuance costs that originated at the time of the May 1998
Recapitalization.

Segment Disclosure

Three and Nine Months Ended December 31, 2001 Compared to Three and Nine Months
Ended December 31, 2000 - Communications Test Products

Bookings for communications test products decreased to $169.1 million for the
three months ended December 31, 2001 as compared to $309.2 million for the same
period a year ago. For the nine months ended December 31, 2001, bookings for
communications test products decreased to $535.6 million as compared to $781.8
million for the same period a year ago. The decrease is a result of the current
global economic slowdown and capital spending cutbacks in the communications
industry.

Net sales of communications test products were $187.2 million for the three
months ended December 31, 2001 as compared to $296.2 million for the same period
a year ago. For the nine months ended December 31, 2001, net sales of
communications test products were $707.7 million as compared to $754.1 million
for the nine months ended December 31, 2000. The decrease for the third quarter
of fiscal 2002 is within all five areas of the communications test businesses,
with the most significant decline for optical transport products. The decrease
for the nine months ended December 31, 2001 is a result of the reduced bookings
as well as the continued pressure on the Company from its customers to reduce
selling prices.

EBITA for the communications test products decreased to a loss of $24.0 million
for the three months ended December 31, 2001 as compared to income of $41.1
million for the same period a year ago. For the nine months ended December 31,
2001, EBITA decreased to $25.3 million as compared to $100.4 million for the
same period a year ago. The decrease is primarily a result of the factors
described above. In addition, the Company recorded a charge of $15 million for
inventory adjustments and other reserves during the third quarter of fiscal 2002
further reducing EBITA for the periods.

Bookings for industrial computing and communications products decreased $13.6
million to $39.8 million for the three months ended December 31, 2001 as
compared to $53.4 million for the same period a year ago. For the nine months
ended December 31, 2001 bookings for this segment decreased $53.7 million to
$107.9 million from $161.6 million for the same period a year ago. The decrease
is in part a result of the sale of ICS Advent during the quarter as well as a
slight decrease in orders at Itronix, as compared to the same period last year.

Net sales of industrial computing and communications products decreased $4.8
million to $41.1 million for the three months ended December 31, 2001 as
compared to $45.9 million for the same period a year ago. For the nine months
ended December 31, 2001 sales within this segment increased $7.8 million to
$143.3 million as compared to $135.5 million for the same period a year ago. The
increase for the nine months ended December 31, 2001 was primarily due to
increased shipments of Itronix's new rugged laptop PC which was introduced to
the market in December 2000.

EBITA for the industrial computing and communications segment was $1.6 million
for the three months ended December 31, 2001 as compared to a loss of $0.9
million for the same period a year ago. For the nine months ended December 31,
2001 EBITA was a loss of $0.1 million as compared to a loss of $4.5 million for
the same period a year ago.

LIQUIDITY AND CAPITAL RESOURCES

General. The Company's liquidity needs arise primarily from debt service on the
substantial indebtedness incurred in connection with the WWG Merger and from the
funding of working capital and capital expenditures. As of December 31, 2001,
the Company had $1,088.4 million of indebtedness, primarily consisting of $275.0
million principal amount of senior subordinated notes, $787.4 million in
borrowings under the Company's senior secured credit facility and $26.0 million
under other debt obligations.

In addition, on January 15, 2002, Acterna LLC, a wholly-owned subsidiary of the
Company, issued and sold at par $75 million aggregate principal amount of 12%
Senior Secured Convertible Notes Due 2007 (the "Notes") to Clayton, Dubilier &
Rice Fund VI Limited Partnership. The Company used the proceeds of the issuance
and sale of the Notes (net of fees and expenses) to repay a portion of its
indebtedness under its revolving credit facility. The amounts repaid remain
available to be reborrowed by the Company. As a result of the repayment, the
Company currently has $96 million of availability under its revolving credit
facility.

On December 27, 2001, the Company entered into an amendment to the credit
agreement (the "Amendment") governing its senior secured credit facility. Under
the Amendment, the lenders under the credit agreement, among other things,
agreed to waive the minimum interest coverage and maximum leverage covenants of
the Company under the credit agreement through June 30, 2003 and consented to
the issuance and sale of the Notes. Under the Amendment, the Company also became
subject to certain additional covenants and restrictions, including, without
limitation, new minimum liquidity and EBITDA requirements and additional
restrictions on the Company's ability to make capital expenditures, incur and
guarantee debt, make investments, optionally prepay the 9.75% Senior
Subordinated Notes Due 2008 and dispose of assets. The Amendment also, among
other things, adds additional prepayment requirements for certain transactions,
establishes additional guarantees and pledges of collateral and increases the
interest rates on loans under the senior secured credit facility by 0.75%. On
June 30, 2003, the Company will again become subject to its minimum interest
coverage and maximum leverage covenants under the


                                       28

<PAGE>

senior secured credit agreement. The Company can make no assurance that it will
be in compliance with these covenants upon such reversion.

The Company's $40 million short-term credit facility expired on December 31,
2001.

Cash Flows. The Company's cash and cash equivalents decreased $12.1 million
during the nine months ended December 31, 2001.

Working Capital. For the nine months ended December 31, 2001, the Company's
working capital decreased as its operating assets and liabilities provided $40.2
million of cash. Accounts receivable decreased, creating a source of cash of
$92.8 million primarily due to the decrease in sales as well as enhanced efforts
to reduce the number of days sales outstanding. Inventory levels decreased,
creating a source of cash of net $15.5 million primarily due to increased focus
on reducing overall inventory levels. Accounts payable decreased, creating a use
of cash of $50.4 million primarily as a result of the Company paying accounts
payable outstanding at March 31, 2001. Other current liabilities decreased,
creating a use of cash of $28.0 million due in part to management incentive
payments made during the first quarter of fiscal year 2002 relating to bonuses
earned during fiscal 2001 as well as the payment of the semi-annual interest
payment on the senior subordinated notes.

Investing activities. The Company's net investing activities totaled $10.6
million for the nine months ended December 31, 2001 due primarily to capital
expenditures of $28.7 million as a result of the WWG Merger. This was offset by
the sale of ICS Advent and another smaller subsidiary for gross cash proceeds of
$23.8 million.

Financing Activities. The Company's financing activities provided $0.2 million
in net cash during the first nine months of fiscal 2002, primarily due to
additional borrowings of cash under the Company's revolving credit facility and
the proceeds from the sale of common stock offset by $4.0 million in debt
financing fees incurred for the Company's credit agreement amendment and the
short-term credit facility.

Future Financing Sources and Cash Flows. As of December 31, 2001, the Company
had $133.0 million of borrowings and $17.0 million of letters of credit
outstanding under its revolving credit facility and $25 million of additional
availability under the facility.

The Company's cash requirements for debt service and ongoing operations are
substantial. While there can be no assurance that the Company will have
sufficient funds or available funds to meet its cash needs over the next twelve
months, as a result of the amendment of the senior secured credit agreement and
the issuance at par of $75 million of 12% Senior Secured Convertible Notes in
January 2002, the Company believes that funds generated by ongoing operations
and funds available under its senior secured credit facility will be sufficient
to meet its cash needs over the next twelve-month period.

In addition, the Company's future operating performance and ability to
repay, extend or refinance the senior secured credit facility (including the
revolving credit facility) or any new borrowings, and to service and repay or
refinance the 12% Senior Secured Convertible Notes due 2007 and the 9.75% Senior
Subordinated Notes due 2008, will be subject to future economic, financial and
business conditions and other factors, including demand for communications test
equipment, many of which are beyond the Company's control. These and other risks
associated with the Company's business are described in the Company's Securities
and Exchange Commission reports, including the Company's Annual Report on Form
10-K for the fiscal year ended March 31, 2001. From time to time, the Company or
its affiliates may purchase debt of the Company on the open market or otherwise,
subject to the


                                       29

terms of the Company's senior and subordinated debt agreements and depending
upon market conditions.

New Pronouncements

In July 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 141, ("FAS 141"), "Business Combinations" and
No. 142 ("FAS 142"), "Goodwill and Other Intangible Assets." FAS No. 141
requires that all business combinations be accounted for under the purchase
method only and that certain acquired intangible assets in a business
combination be recognized as assets apart from goodwill. FAS No. 142 requires
that ratable amortization of goodwill be replaced with periodic tests of the
goodwill's impairment and that intangible assets other than goodwill be
amortized over their useful lives. FAS No. 141 is effective for all business
combinations initiated after June 30, 2001 and for all business combinations
accounted for by the purchase method for which the date of acquisition is before
June 30, 2001. The provisions of FAS No. 142 will be effective for fiscal years
beginning after December 15, 2001; however, the Company has elected to early
adopt the provisions effective April 1, 2001.

In October 2001, the Financial Accounting Standards Board Statement of Financial
Accounting Board issued Statement of Financial Accounting Standards No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets" ("FAS 144").
FAS 144 supercedes FASB Statement No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of". FAS 144 applies
to all long-lived assets (including discontinued operations) and consequently
amends Accounting Principles Board Opinion No. 30, "Reporting Results of
Operations- Reporting the Effects of Disposal of a Segment of a Business". FAS
144 is effective for financial statements issued for fiscal years beginning
after December 15, 2001, and will thus be adopted by the Company, as required,
on April 1, 2002. Management is currently determining what effect, if any, FAS
144 will have on its financial position and results of operations.

Quantitative and Qualitative Disclosures about Market Risk

The Company operates manufacturing facilities and sales offices in over 80
countries. The Company is subject to business risks inherent in non-U.S.
activities, including political and economic uncertainty, import and export
limitations, and market risk related to changes in interest rates and foreign
currency exchange rates. The Company believes the political and economic risks
related to its foreign operations are mitigated due to the stability of the
countries in which its facilities are located. The Company's principal currency
exposures against the U.S. dollar are in the Euro and in Canadian currency. The
Company does use foreign currency forward exchange contracts to mitigate
fluctuations in currency. The Company's market risk exposure to currency rate
fluctuations is not material. The Company does not hold derivatives for trading
purposes.

The Company uses derivative financial instruments consisting primarily of
interest rate hedge agreements to manage exposures to interest rate changes. The
Company's objective in managing its exposure to changes in interest rates (on
its variable rate debt) is to limit the impact of such changes on earnings and
cash flow and to lower its overall borrowing costs.

At December 31, 2001, the Company had $787.4 million of variable rate debt
outstanding, which represents approximately 72% of the Company's total
outstanding debt. The Company currently has one interest rate swap contract with
notional amounts totaling $130 million which fixed its variable rate debt to a
fixed interest rate for periods of two years in which the Company pays a fixed
interest


                                       30

<PAGE>

rate on a portion of its outstanding debt and receives interest at the
three-month LIBOR rate.

At December 31, 2001, the swap contract currently outstanding and the swap
contract that expired had fixed interest rates higher than the three-month LIBOR
quoted by its financial institutions. The Company therefore recognized an
increase in interest expense (calculated as the difference between the interest
rate in the swap contracts and the three-month LIBOR rate) for the first nine
months of fiscal 2002 of $1.0 million. The Company performed a sensitivity
analysis assuming a hypothetical 10% adverse movement in the floating interest
rate on the interest rate sensitive instruments described above. The Company
believes that such a movement is reasonably possible in the near term. As of
December 31, 2001, the analysis demonstrated that such movement would cause the
Company to recognize additional interest expense of approximately $0.2 million,
and accordingly, would cause a hypothetical loss in cash flows of approximately
$0.2 million on an annual basis.

The Company has significant debt and resulting debt service obligations. A
substantial portion of the debt is subject to variable rate interest expense.
The weighted average interest rate for the nine months ended December 31, 2001
was 8.1%. Interest rates are at historically low rates and an increase in
interest rates in the future could have a material impact on the results of
operations and financial position of the Company. An increase of 100 basis
points in interest rates would increase interest expense by approximately $8.0
million on an annual basis.

PART II. Other Information

Item 1.  Legal Proceedings

The Company is a party to several pending legal proceedings and claims. Although
the outcome of such proceedings and claims cannot be determined with certainty,
the Company believes that the final outcome should not have a material adverse
effect on the Company's operations or financial position.

In 1994, the Company sold its radar detector business to Whistler Communications
of Massachusetts. On June 27, 1996, Cincinnati Microwave, Inc. ("CMI"), filed an
action in the United States District Court for the Southern District of Ohio
against the Company and Whistler Corporation, alleging willful infringement of
CMI's patent for a mute function in radar detectors. On September 26, 2000, the
Federal District Court Judge granted the Company's motion for partial summary
judgment on the affirmative defense of laches, and the case was administratively
terminated. The decision was appealed by CMI, and on December 17, 2001, the
United States Court of Appeals for the Federal Circuit affirmed the ruling in
favor of the Company by the Federal District Court.
