NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

A. MERGER/RECAPITALIZATION

   On May 21, 1998 the Company completed its management-led merger with a
   company formed at the direction of Clayton, Dubilier & Rice, Inc. ("CDR")
   (the "Merger"). The Merger and related transactions were treated as a
   recapitalization (the "Recapitalization") for financial reporting purposes.
   Accordingly, the historical basis of the Company's assets and liabilities was
   not affected by these transactions.

B. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

   In the opinion of management, the unaudited condensed consolidated balance
   sheet at June 30, 1998, and the unaudited consolidated statements of income
   and unaudited consolidated condensed statements of cash flows for the interim
   periods ended June 30, 1998 and 1997 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 condensed or omitted. The March 31, 1998 balance sheet
   data was derived from audited financial statements, but does not include
   disclosures required by generally accepted accounting principles. It is
   suggested that these condensed statements be read in conjunction with the
   Company's most recent Form 10-K as of March 31, 1998.

   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, and
   tax valuation reserves. Actual results could differ from those estimates.

C. NEW PRONOUNCEMENTS

   The Financial Accounting Standards Board issued Statement No. 131 ("SFAS
   131"), "Disclosures about Segments of an Enterprise and Related Information,"
   which establishes standards for the reporting of operating segments in the
   financial statements. The Company is required to adopt SFAS 131 in the fourth
   quarter of fiscal 1999 and its adoption is not expected to have a material
   impact on the Company's disclosures.

   On June 15, 1998, the Financial Accounting Standards Board issued Statement
   of Financial Accounting Standards No. 133 ("SFAS 133"), "Accounting for
   Derivative Instruments and Hedging Activities."  SFAS 133 is effective for
   all fiscal quarters of all fiscal years beginning after June 15, 1999.  SFAS
   133 requires that all derivative instruments be recorded on the balance sheet
   at their fair value.  Changes in the fair value of derivatives are recorded
   each period in current earnings or other comprehensive income, depending on
   whether a derivative is designated as part of a hedge transaction and, if it
   is, the type of hedge transaction.  The Company anticipates that, due to its
   limited use of derivative instruments, the adoption of SFAS 133 will not have
   a significant effect on the Company's results of operations or its financial
   position.

                                       5

D. COMPREHENSIVE INCOME

   In the quarter ended June 30, 1998, the Company adopted Statement of
   Financial Accounting Standards No. 130 ("SFAS 130") "Reporting Comprehensive
   Income."  SFAS 130 establishes standards for the reporting and display of
   comprehensive income and its components.  SFAS 130 requires, among other
   things, foreign currency translation adjustments which, prior to adoption,
   were reported separately in stockholders' equity to be included in other
   comprehensive income.

E. INCOME (LOSS) PER SHARE

   The Company adopted Statement of Financial Accounting Standards No. 128,
   "Earnings per Share," which modifies the calculation of earnings per share
   ("EPS"). The Standard replaces the previous presentation of primary and fully
   diluted EPS to basic and diluted EPS. Basic EPS excludes dilution and is
   computed by dividing income available to common stockholders by the weighted
   average number of common shares outstanding for the period. Diluted EPS
   includes the dilution of common stock equivalents, and is computed similarly
   to fully diluted EPS pursuant to APB Opinion 15. All prior periods presented
   have been restated to reflect this adoption.

(a) As of June 30, 1998, the Company had options outstanding to purchase 19.5
    million shares of common stock that were excluded from the diluted earnings
    per share computation as the effect of their inclusion would have been
    antidilutive.

The loss per share and weighted average common shares outstanding for the
three months ended June 30, 1998 is based on the Company's recapitalized
structure.  The income per share for the three months ended June 30, 1997 is
based on the Company's capital structure at that time (prior to the Merger).

   In connection with the Merger, the Company entered into a senior secured
   credit agreement (the "Senior Secured Credit Agreement") consisting of a $260
   million term loan facility (the "Term Loan Facility") and a $110 million
   revolving credit facility, (the "Revolving Credit Facility") (collectively,
   the "Senior Secured Credit Facilities"). In addition, the Company incurred
   $275 million of debt through the sale of its 9 3/4% Senior Subordinated Notes
   (the "Senior Subordinated Notes"). Principal and interest payments under the
   new Senior Secured Credit Agreement and interest payments on the Senior
   Subordinated Notes represent significant liquidity requirements for the
   Company. With respect to the $260 million borrowed under the Term Loan
   Facility, in which the facility is divided into tranches, of which each
   tranche has a different term and repayment schedule, the Company will be
   required to make scheduled principal payments of $50 million of tranche A
   term loan thereunder of its six year term, with substantial amortization of
   the $70 million of tranche B term loan, $70 million of tranche C term loan
   and $70 million tranche D term loan thereunder occurring after six, seven and
   eight years, respectively. The $275 million of Senior Subordinated Notes will
   mature in 2008, and bear interest at 9 3/4%. Total interest expense is
   expected to be approximately $51 million in fiscal 1999. The Senior Secured
   Credit Facilities are also subject to mandatory prepayment and reduction in
   an amount equal to, subject to certain exceptions, (a) 100% of the net
   proceeds of (i) certain debt offerings by the Company and any of its
   subsidiaries, (ii) certain asset sales by the Company or any of its
   subsidiaries, and (iii) casualty insurance, condemnation awards or other
   recoveries received by the Company or any of its subsidiaries, and (b) 50% of
   the Company's excess cash flow (as defined) for each fiscal year in which the
   Company exceeds a certain leverage ratio. The Senior Subordinated Notes are
   subject to certain mandatory prepayments under certain circumstances. The
   Revolving Credit Facility matures in 2004, with all amounts then outstanding
   becoming due. The Company expects that its working capital needs will require
   it to obtain new revolving credit facilities at the time that the Revolving
   Credit Facility matures, whether by extending, renewing, replacing or
   otherwise refinancing the Revolving Credit Facility. No assurance can be
   given that any such extension, renewal, replacement or refinancing can be
   successfully accomplished. The loans under the Senior Secured Credit
   Agreement bear interest at floating rates based upon the interest rate option
   elected by the Company. However, the Company has entered into interest rate
   swaps which will be effective for three years beginning September 30, 1998 to
   fix the interest rate charged on a portion of the total debt outstanding
   under the Term Loan Facility. After giving effect to these arrangements,
   approximately $195 million of the debt outstanding will be subject to an
   effective average annual fixed interest rate of 5.84% plus an applicable
   margin. As a result of the substantial indebtedness incurred in connection
   with the Merger, it is expected that the Company's interest expense will be
   higher and will have a greater proportionate impact on net income in
   comparison to preceding periods.

   Future financing Sources and Cash Flows.  The amount under the Revolving
   Credit Facility that remained undrawn at June 30, 1998 was $70 million.  The
   undrawn portion of this facility will be available to meet future working
   capital and other business needs of the Company.  The Company believes that
   cash generated from operations, together with amounts available under the
   Revolving Credit Facility and any other available sources of liquidity, will
   be adequate to permit the Company to meet its debt service obligations,
   capital expenditure program requirements, ongoing operating costs and working
   capital needs, although no assurance can be given in this regard.  The
   Company's future operating performance and ability to service or refinance
   the Senior Subordinated Notes and to repay, extend or refinance the Senior
   Secured Credit Facilities (including the Revolving Credit Facility) will be,
   among other things, subject to future economic conditions and to financial,
   business and other factors, many of which are beyond the Company's control.

                                       8

   Covenant Restrictions.  The Senior Secured Credit Agreement imposes
   restrictions on the ability of the Company to make capital expenditures and
   both the Senior Secured Credit Facilities and the indenture governing the
   Senior Subordinated Notes limit the Company's ability to incur additional
   indebtedness. Such restrictions, together with the highly leveraged nature of
   the Company, could limit the Company's ability to respond to market
   conditions, to meet its capital-spending program, to provide for
   unanticipated capital investments, or to take advantage of business
   opportunities.  The covenants contained in the Senior Secured Credit
   Agreement also, among other things, restrict the ability of the Company and
   its subsidiaries to dispose of assets, incur guarantee obligations, prepay
   other indebtedness, make restricted payments, create liens, make equity or
   debt investments, make acquisitions, modify terms of the indenture governing
   the Senior Subordinated Notes, engage in mergers or consolidations, change
   the business conducted by the Company and its subsidiaries taken as a whole
   or engage in certain transactions with affiliates.  In addition, under the
   Senior Secured Credit Agreement, the Company is required to comply with a
   minimum interest expense coverage ratio and a maximum leverage ratio.  These
   financial tests become more restrictive in future years.  The term loans
   under the Senior Secured Credit Facility (other than the $50 million tranche
   A term loan) have negative covenants which are substantially similar to the
   negative covenants contained in the indenture governing the Senior
   Subordinated Notes, which also impose restrictions on the operation of the
   Company's business.

G. OTHER ASSETS

   In connection with the Merger, the Company incurred financing fees which will
   be amortized over the life of the Senior Secured Credit Facilities and Senior
   Subordinated Notes. In addition, a deferred tax asset of $5.5 million was
   generated as a result of modifications to stock options in the
   recapitalization.

   The detail of Other Assets is as follows:

I. RELATED PARTY

   During the quarter ended June 30, 1998, the Company paid a one-time
   transaction fee of $9.2 million and will pay an annual management fee of $500
   thousand to CDR.  In exchange for the transaction fee, CDR provided services
   to arrange the Recapitalization/Merger and the financing for the Merger. In

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

This Form 10-Q contains forward-looking statements which 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 impact 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, 1998.

The Merger.  On May 21, 1998 the Company was merged with and into CDRD Merger
Corporation ("MergerCo"), a nonsubstantive transitory merger vehicle organized
at the direction of Clayton, Dubilier & Rice, Inc. ("CDR"), a private investment
firm, with the Company continuing as the surviving corporation ("the Merger").
In the Merger, (i) each then outstanding share of common stock, par value $0.20
per share, of the Company (the "Common Stock") was converted into the right to
receive $47.75 in cash and 0.5 shares of common stock, no par value, of the
Company (the "Recapitalized Common Stock") and (ii) each then outstanding share
of common stock of MergerCo was converted into one share of Recapitalized Common
Stock.

As a result of the Merger, Clayton, Dubilier & Rice Fund V Limited Partnership,
an investment partnership managed by CDR "(CDR Fund V") holds approximately
92.3% of the Recapitalized Common Stock.  John F. Reno, the Chairman, President
and Chief Executive Officer of the Company together with two family trusts holds
approximately 0.7% of the Recapitalized Common Stock and other stockholders hold
approximately 7.0% of the Recapitalized Common Stock.

The Merger and related transactions were treated as a Recapitalization for 
financial reporting purposes. Accordingly, the historical basis of the Company's
assets and liabilities was not affected by these transactions.

Acquisitions. On June 19, 1998 the Company, through one of its indirect wholly
owned subsidiaries, acquired all of the outstanding capital stock of Pacific
Systems Corporation of Kirkland, Washington ("Pacific") for a total purchase
price of $20 million, including an incentive earnout. The Company generated 
$17.8 million of goodwill related to this acquisition. Pacific designs and
manufactures customer-specified avionics and integrated cabin management
equipment for the corporate and general aviation market.

Sale of Subsidiary. On June 30, 1998 the Company sold the assets of ComCoTec,
Inc. ("ComCoTec") located in Lombard, Illinois to The Potomac Group, Inc. for
$21 million with $1 million remaining in escrow pending any purchase price
adjustments which resulted in a gain of $15.9 million. ComCoTec is a supplier of
pharmacy management software and services and was a subsidiary within the
Company's visual communications products group.

Sales.  Consolidated sales increased $4.8 million or 4.6% to $109.1 million for
the three months ended June 30, 1998 as compared to $104.3 million for the same
period a year ago.

Sales of communications test products decreased $3.2 million to $53.8 million or
5.6% over the same period last year.  This was the result of reduced demand for
hand-held test devices plus a slowdown of orders from the Regional Bell
Operating Companies ("RBOCs") due to the lengthening of the sales cycle during a
period of industry consolidation.

Sales for industrial computing and communication products increased $5.3 million
to $34.0 million or 18.4% over the same period last year. The increase was
primarily attributable to additional sales volume of the Company's ruggedized
laptop computers due to fewer Pentium-based field-service units shipped during
the first quarter of last year while the products continued final testing.

                                       11
<PAGE>
 
Sales of visual communications products increased $2.8 million to $18.9 million
or 15.0% over the same period last year.  Sales for the Company's real-time
flight information passenger video displays continued to be strong. Offsetting
this increase were lower sales in the video compression and graphical user-
interface (GUI) products. 

Gross Profit.  Consolidated gross profit increased $1.3 million to $63.0 million
or 57.7% of consolidated sales for the three months ended June 30, 1998 as
compared to $61.7 million or 59.1% of consolidated sales for the same period a
year ago.  The percentage decrease was attributable to a change in the product
mix of the Company. The Company had increased shipments of ruggedized laptop
computers which sell at a lower gross margin and fewer shipments of
communications test products that have a higher gross margin than the
consolidated family of products.

Operating Expenses.  Operating expenses consist of selling, marketing and
distribution expense; general and administrative expense; product development
expense; recapitalization related costs; and amortization of intangibles.  Total
operating expenses were $93.5 million or 85.7% of consolidated sales for the 
three months ended June 30, 1998 as compared to $46.9 million or 45.0% of
consolidated sales for the same period last year. Included in this quarter's
operating expenses were the expenses related to the Merger for the option
cancellation payments. Excluding these expenses, operating expenses for the
three months ended June 30, 1998 were $50.1 million or 45.9% of consolidated
sales. The increase in percentage was primarily attributable to increased
selling and marketing expense.

Selling, general and administrative expense was $35.2 million or 32.2% of
consolidated sales for the three months ended June 30, 1998, compared to $31.8
million or 30.4% of consolidated sales for the same period a year ago. The
increase in percentage was primarily attributable to increased commission and
compensation expense during the first quarter of fiscal 1999 as well as
additional expenses related to catalog costs for the Company's Industrial
Computer Source-Book.

Product development expense was $13.5 million or 12.4% of consolidated sales for
the three months ended June 30, 1998 as compared to $13.7 million or 13.1% of
consolidated sales for the same period last year. The decrease was primarily
driven by a higher product development expense for the same period last year in
which the Company incurred for the introduction of Pentium-based ruggedized
laptops.

Recapitalization related costs. In connection with the Merger, the Company
incurred $43.4 million for the cancellation payments of employee stock options,
compensation expense due to the acceleration of unvested stock options, and
other merger-related expenses. The Company incurred an additional $41.3 million
in expenses, of which $27.3 million was capitalized and will be amortized over
the life of the Senior Secured Credit Facilities and Senior Subordinated Notes,
and $14.0 million was charged directly to shareholder's equity.

Amortization of intangibles during the first quarter of both fiscal 1999 and
1998 was $1.4 million.

Interest.  Interest expense, net of interest income, was $5.3 million for the
first quarter of fiscal 1999 as compared to net interest income of $0.1 million
for the same period last year.  The increase in net interest expense was
attributable to the debt incurred in connection with the Merger on May 21, 1998.

                                       12
<PAGE>
 
Other income.  Other income for the first quarter was $32 thousand as compared
to $170 thousand for the same period a year ago.

Taxes. The effective tax rate for the first quarter was 40.0%, essentially at 
the same level as the same period a year ago.

Net income (loss).  The Company's net loss was $11.9 million or $(0.19) per
share on a diluted basis for the three months ended June 30, 1998 as compared to
net income  of $9.0 million or $0.52 per share on a diluted basis for the same
period a year ago.  The loss was primarily attributable to both the cancellation
payments of the employee stock options plus the additional interest expense
incurred in connection with the Merger.

Backlog.  Backlog at June 30, 1998 was $88.8 million, an increase of $9.7
million over the backlog at March 31, 1998.

Capital Resources and Liquidity

Cash flows.  The Company's cash and cash equivalents decreased $13 million
during the first three months of fiscal 1999 principally due to the 
Recapitalization of the Company. 

Working Capital.  During the first quarter of fiscal 1999, the Company's working
capital increased as its operating assets and liabilities provided a $4.3
million source of cash excluding the acquisition of Pacific. Inventory levels
increased, creating a use of cash of $400 thousand.  Accounts receivable
decreased from $70.0 million to $58.8 million, or a source of cash of $11.1
million, as a result of improved collection processes at the Company. Other
current assets decreased, creating a source  of cash of $3.0 million due mainly
to the recognition of expenses previously capitalized related to the Merger.
Accounts payable decreased, creating a use of cash of $6.3 million.  Other
current liabilities decreased, creating a use of cash of $3.1 million, relating
primarily to the payment of bonuses previously accrued.

Investing Activities. The Company's investing activities totaled $6.1 million
primarily for the purchase and replacement of property and equipment and the
payment of an earnout incentive related to the fiscal 1998 operating result of
Advent Design, Inc., a subsidiary purchased in March 1997. Also included in this
total are the proceeds received from the sale of ComCoTec, offset by the
purchase of Pacific. The Company's capital expenditures were $2.4 million
compared with $4.0 million for the same period last year. The decrease is
primarily due to the timing of certain capital expenditure purchases. The
Company anticipates capital expenditures to be at the same level in fiscal year
1999 as in fiscal year 1998.

Debt and Equity. The Company's financing activities generated $2.8 million in
cash after $573 M of net proceeds from borrowing and $277 million from issuance
of stock related to the Merger were used to pay $806.5 million for the purchase
of the outstanding stock and $41.3 million for financing fees related to the
Merger.

In connection with the Merger, the Company entered into a senior secured credit
agreement (the "Senior Secured Credit Agreement") consisting of a $260 million
term loan facility (the "Term Loan Facility") and a $110 million revolving
credit facility, (the "Revolving Credit Facility") (collectively, the "Senior
Secured Credit Facilities"). In addition, the Company incurred $275 million of
debt through the sale of its 9 3/4% Senior Subordinated Notes (the "Senior
Subordinated Notes"). Principal and interest payments under the new Senior
Secured Credit Agreement and interest payments on the Senior Subordinated Notes
represent significant liquidity requirements for the Company. With respect to
the $260.0 million borrowed under the Term Loan Facility, in which the facility
is divided into tranches, of which each tranche has a different term and
repayment schedule, the Company will be

                                      13
<PAGE>
 
required to make scheduled principal payments of $50 million of tranche A term
loan thereunder of its six year term, with substantial amortization of the $70
million of tranche B term loan, $70 million of tranche C term loan and $70
million tranche D term loan thereunder occurring after six, seven and eight
years, respectively. The $275 million of Senior Subordinated Notes will mature
in 2008, and bear interest at 9 3/4%. Total interest expense is expected to be
approximately $51 million in fiscal 1999. The Senior Secured Credit Facilities
are also subject to mandatory prepayment and reduction in an amount equal to,
subject to certain exceptions, (a) 100% of the net proceeds of (i) certain debt
offerings by the Company and any of its subsidiaries, (ii) certain asset sales
by the Company or any of its subsidiaries, and (iii) casualty insurance,
condemnation awards or other recoveries received by the Company or any of its
subsidiaries, and (b) 50% of the Company's excess cash flow (as defined) for
each fiscal year in which the Company exceeds a certain leverage ratio. The
Senior Subordinated Notes are subject to certain mandatory prepayments under
certain circumstances. The Revolving Credit Facility matures in 2004, with all
amounts then outstanding becoming due. The Company expects that its working
capital needs will require it to obtain new revolving credit facilities at the
time that the Revolving Credit Facility matures, whether by extending, renewing,
replacing or otherwise refinancing the Revolving Credit Facility. No assurance
can be given that any such extension, renewal, replacement or refinancing can be
successfully accomplished. The loans under the Senior Secured Credit Agreement
bear interest at floating rates based upon the interest rate option elected by
the Company. However, the Company has entered into interest rate swaps which
will be effective for three years beginning September 30, 1998 to fix the
interest rate charged on a portion of the total debt outstanding under the Term
Loan Facility. After giving effect to these arrangements, approximately $195
million of the debt outstanding will be subject to an effective average annual
fixed interest rate of 5.84% plus an applicable margin. As a result of the
substantial indebtedness incurred in connection with the Merger, it is expected
that the Company's interest expense will be higher and will have a greater
proportionate impact on net income in comparison to preceding periods.

Future financing Sources and Cash Flows.  The amount under the Revolving Credit
Facility that remained undrawn at June 30, 1998 was $70 million.  The undrawn
portion of this facility will be available to meet future working capital and
other business needs of the Company.  The Company believes that cash generated
from operations, together with amounts available under the Revolving Credit
Facility and any other available sources of liquidity, will be adequate to
permit the Company to meet its debt service obligations, capital expenditure
program requirements, ongoing operating costs and working capital needs for at
least the next twelve months, although no assurance can be given in this regard.
The Company's future operating performance and ability to service or refinance
the Senior Subordinated Notes and to repay, extend or refinance the Senior
Secured Credit Facilities (including the Revolving Credit Facility) will be,
among other things, subject to future economic conditions and to financial,
business and other factors, many of which are beyond the Company's control.

Covenant Restrictions.  The Senior Secured Credit Agreement imposes restrictions
on the ability of the Company to make capital expenditures and both the Senior
Secured Credit Facilities and the indenture governing the Senior Subordinated
Notes limit the Company's ability to incur additional indebtedness. Such
restrictions, together with the highly leveraged nature of the Company, could
limit the Company's ability to respond to market conditions, to meet its
capital-spending program, to provide for unanticipated capital investments, or
to take advantage of business opportunities.  The covenants contained in the
Senior Secured Credit Agreement also, among other things, restrict the ability
of the Company and its subsidiaries to dispose of assets, incur guarantee
obligations, prepay other indebtedness, make restricted payments, create liens,
make equity or debt investments, make acquisitions, modify terms of the
indenture governing the Senior Subordinated Notes, engage in mergers or
consolidations, change the business conducted by the Company and its
subsidiaries taken as a whole 

                                       14
<PAGE>
 
or engage in certain transactions with affiliates. In addition, under the Senior
Secured Credit Agreement, the Company is required to comply with a minimum
interest expense coverage ratio and a maximum leverage ratio. These financial
tests become more restrictive in future years. The term loans under the Senior
Secured Credit Facility (other than the $50 million tranche A term loan) have
negative covenants which are substantially similar to the negative covenants
contained in the indenture governing the Senior Subordinated Notes, which also
impose restrictions on the operation of the Company's business.

Year 2000

The Company has commenced a review of its computer systems and products in order
to assess its exposure to Year 2000 issues.  The Company is currently in the
process of determining the full scope, related costs and action plan to insure
that the Company's systems continue to meet its internal needs and those of its
customers.  The Company expects to make the necessary modifications or changes
to its computer information systems to enable proper processing of transactions
relating to the Year 2000 and beyond.  However, there can be no assurance that
Year 2000 costs and expenses will not have a material adverse effect on the
Company.  In addition, the Company does not currently have complete information
concerning the Year 2000 compliance status of its suppliers and customers.  In
the event that any of the Company's significant suppliers or customers do not
successfully and timely achieve Year 2000 compliance, the Company's business or
operations could be materially adversely affected.  Finally, there can be no
assurance that the Company's existing or installed base of products are Year
2000 compliant, or that the Company's products will not be integrated by the
Company or its customers with, or otherwise interact with, non-compliant
software or other products.  Any such product non-compliance may expose the
Company to claims from its customers and others, and could impair market
acceptance of the Company's products and services, increase service and warranty
costs, or result in payment of damages, which in turn could materially adversely
affect the Company.

New Pronouncements

In the quarter ended June 30, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130 (SFAS 130) "Reporting Comprehensive Income."  SFAS
130 establishes standards for the reporting and display of comprehensive income
and its components.  SFAS 130 requires, among other things, foreign currency
translation adjustments, which prior to adoption were reported separately in
stockholders' equity to be included in other comprehensive income.

In the quarter ended June 30, 1998, the Company adopted Statement of Position
97-2, "Software Revenue Recognition" ("SOP 97-2").  SOP 97-2 provides guidance
on applying generally accepted accounting principles in recognizing revenue on
software transactions.

The Financial Accounting Standards Board issued Statement No. 131 ("SFAS 131"),
"Disclosures about Segments of an Enterprise and Related Information," which
establishes standards for the reporting of operating segments in the financial
statements.  The Company is required to adopt SFAS 131 in the fourth quarter of
fiscal 1999 and its adoption is not expected to have a material impact on the
Company's disclosures.

On June 15, 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards 133 ("SFAS 133"), "Accounting for

                                       15
<PAGE>
 
Derivative Instruments and Hedging Activities."  SFAS 133 is effective for all
fiscal quarters of all fiscal years beginning after June 15, 1999.  SFAS 133
requires that all derivative instruments be recorded on the balance sheet at
their fair value.  Changes in the fair value of derivatives are recorded each
period in current earnings or other comprehensive income, depending on whether a
derivative is designated as part of a hedge transaction and, if it is, the type
of hedge transaction.  The Company anticipates that, due to its limited use of
derivative instruments, the adoption of SFAS 133 will not have a significant
effect on the Company's results of operations or its financial position.

PART II. Other Information

Item 1. Legal Proceedings

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 of Massachusetts ("Whistler"), alleging willful
infringement of CMI's patent for a mute function in radar detectors. In 1994, 
the Company sold its radar detector business to Whistler. The Company and 
Whistler have asserted in response that they have not infringed, and that the 
patent is invalid and unenforceable. The Company obtained an opinion of counsel 
from Bromberg & Sunstein LLP in connection with the manufacture and sale of the 
Company's Whistler series radar detectors and will be offering the opinion, 
among other things, as evidence that any alleged infringement was not willful. 
On March 24, 1998, CMI, together with its co-plaintiff and patent assignee 
Escort, Inc., moved for summary judgment. The Company and Whistler have opposed 
the motion for summary judgment. The Company intends to defend the lawsuit 
vigorously and does not believe that the outcome of the litigation is likely to 
have a material adverse effect on the Company's financial condition, results of 
operations or liquidity.

Item 2. Changes in Securities and Use of Proceeds

On May 21, 1998, the Company was merged with MergerCo. In the Merger, (i) each
then outstanding share of Common Stock of the Company was converted into the
right to receive $47.75 in cash and 0.5 shares of Recapitalized Common Stock,
which shares were registered on a Registration Statement on Form S-4 and (ii)
the then outstanding 111,590,528 shares of common stock of MergerCo were
converted on a one-for-one basis into an equal number of shares of Recapitalized
Common Stock pursuant to the exemption from registration provided by Section
4(2) of the Securities Act of 1933, as amended.
