Non-cash activity: During the six months ended March 31, 1999, the Company
transferred its wafer fabrication facilities in Colorado Springs, Colorado, (and
the related tax benefit) with a book value of $58 million to Rockwell, as well
as certain other tax benefits of $23 million related to the Celeritas
litigation. In addition, Rockwell transferred $64 million of restricted cash to
Conexant to be used to satisfy the $65 million liability which Conexant recorded
in the year ended September 30, 1998, related to the Celeritas judgment. During
the second fiscal quarter of 1999, the restricted cash balance of $64 million
transferred from Rockwell was used to settle the Celeritas judgment, the
additional $1 million paid directly by Rockwell was recorded as additional
paid-in capital, and the corresponding $65 million liability was eliminated.

                             CONEXANT SYSTEMS, INC.

         NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

On December 31, 1998, Conexant Systems, Inc. (formerly named Rockwell
Semiconductor Systems, Inc.) (the Company or Conexant), became an independent,
separately traded, publicly-held company when Rockwell International Corporation
(Rockwell) spun off its semiconductor systems business (Semiconductor Systems)
by means of the distribution (the Distribution) of all the outstanding shares of
common stock of the Company to the shareholders of Rockwell in a tax-free
spin-off. In the Distribution, each Rockwell shareholder of record on December
11, 1998, received one share of the Company's common stock (including an
associated preferred share purchase right) for every two shares of Rockwell
common stock owned on December 11, 1998.

The unaudited consolidated condensed financial statements of Conexant have been
prepared in accordance with generally accepted accounting principles, which
require management to make estimates and assumptions that affect the amounts
reported in the financial statements. Actual results could differ from those
estimates. In the opinion of the management of Conexant, the unaudited financial
statements contain all adjustments, consisting of adjustments of a normal
recurring nature, as well as the special charges recorded in the first quarter
of 1999 (see Notes 2 and 3), necessary to present fairly the financial position,
results of operations, and cash flows for the periods presented. Certain
reclassification entries have been made to prior periods for consistency
purposes. These statements should be read in conjunction with the Company's
Registration Statement on Form 10, as amended, as filed with the Securities and
Exchange Commission. The results of operations for the second fiscal quarter and
six months ended March 31, 1999, are not necessarily indicative of the results 
that may be expected for the full year.

The accompanying unaudited consolidated condensed financial statements present
the historical financial position, results of operations, and cash flows of
Semiconductor Systems, as it was spun off, and exclude the assets, liabilities,
and results of operations of non-semiconductor businesses retained by Rockwell.
These financial statements are not necessarily indicative of what the financial
position, results of operations, or cash flows would have been had Conexant been
an independent public company during all periods presented. Financial data
included in the accompanying unaudited consolidated condensed financial
statements, for periods subsequent to the Distribution, have been prepared on a
basis that reflects the historical assets, liabilities, and operations of the
business contributed to Conexant by Rockwell.

For presentation purposes, references made to the March 31, 1999, and March 31,
1998, periods relate to the second fiscal quarter-ends, which are actually April
2, 1999, and April 3, 1998, respectively. In addition, references made to the
December 31, 1998, period relate to the first fiscal quarter-end, which is
actually January 1, 1999, as previously reported.

Prior to the Distribution, Rockwell provided certain management services that
were allocated based on sales in proportion to total Rockwell sales. Rockwell
continues to provide certain services to the Company, including payroll and
employee benefits administration, data processing and telecommunications
services, and research and development activities under the terms of a
transition agreement. Costs for these services and programs are billed to
Conexant based on actual usage and are included in Conexant's Unaudited
Consolidated Condensed Statements of Operations. Management believes that the 


                                       6
<PAGE>   7

methods of billing these costs are reasonable and that the costs charged to
Conexant are approximately those which would have been incurred on a stand-alone
basis.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("FAS 133"), "Accounting for Derivative
Instruments and Hedging Activities." FAS 133 is effective for Conexant's fiscal
year beginning October 1, 1999. This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It requires
that the Company recognize all derivative instruments as either assets or
liabilities in the Unaudited Consolidated Condensed Balance Sheets and measure
those instruments at fair value. Management believes the impact of adopting this
standard will not be material to the financial position or results of operations
of the Company.

2. SPECIAL CHARGES - ROCKWELL RETAINED ASSETS

Prior to the Distribution, the Company distributed its wafer fabrication
facilities in Colorado Springs, Colorado, (and the related tax benefit) to
Rockwell. The transition agreement with Rockwell provides for the lease of the
Colorado Springs facilities by Conexant through April 30, 1999, pursuant to a
triple-net lease under which Conexant will pay all costs of the facilities.

In the first fiscal quarter of 1999, Conexant recorded a special charge for an
additional asset impairment of $20 million for the Colorado Springs wafer
fabrication facilities as a result of Rockwell's decision to further write-down
the facilities, which were retained by Rockwell as part of the spin-off. This
non-cash charge was required to be reported in the Company's last fiscal quarter
as a subsidiary of Rockwell.

3. SPECIAL CHARGES - OTHER

In the fourth fiscal quarter of 1998, Conexant restructured its business and
recorded special charges of $147 million. In the first fiscal quarter of 1999,
Conexant recorded additional special charges of $18 million. At March 31, 1999,
$28.7 million of accruals remained for these special charges relating primarily
to contract cancellations, facility lease termination costs and equipment
decommissioning. The restructuring actions are expected to be substantially
completed by the end of fiscal year 1999.

4. INVENTORIES

Inventories are summarized as follows (in thousands):

</TABLE>


5. REPORTING COMPREHENSIVE INCOME

Effective October 1, 1998, the Company adopted Statement of Financial Accounting
Standards No. 130 ("FAS 130"), "Reporting Comprehensive Income." This statement 




                                       7
<PAGE>   8

requires the Company to report in the financial statements, in addition to net
income (loss), comprehensive income (loss) and its components. Comprehensive
income (loss) for the three- and six-month periods ended March 31, 1999, was
$10.1 million and $(47.0) million, respectively. Accumulated other comprehensive
income includes $0.6 million in translation gain and $1.9 million of unrealized
gains on investments at March 31, 1999. Translation gains and losses for periods
prior to the Distribution were reflected as part of Rockwell's net investment
and were not considered material.

6.  CONTINGENT LIABILITIES

Claims have been asserted against Conexant for utilizing the intellectual
property rights of others in certain of the Company's products. The resolution
of these matters may entail the negotiation of a license agreement, a
settlement, or the resolution of such claims through arbitration or litigation.

In September 1995, Celeritas Technologies, Ltd., filed suit against Rockwell, in
U.S. District Court for the Central District of California, for patent
infringement, misappropriation of trade secrets, and breach of contract relating
to cellular telephone data transmission technology utilized in certain modem
products produced by the Company. In July 1997, the Court entered a judgment
awarding damages of $57 million, plus interest. On July 20, 1998, the U.S. Court
of Appeals for the Federal Circuit affirmed the trial court's judgment based on
breach of contract. As of September 30, 1998, $65 million was reserved for this
matter. During the first fiscal quarter of 1999, Rockwell contributed $64
million into an escrow account related to this judgment which was subsequently
paid to Celeritas on February 11, 1999, in final settlement of the judgment. 
The remaining $1 million of this liability was paid directly by Rockwell and 
recorded as additional paid in capital, and the corresponding $65 million 
liability was eliminated.

On October 14, 1997, Brent Townshend filed suit against Rockwell and Conexant in
the Superior Court of California for San Mateo County seeking an injunction to
halt the sale of products containing Conexant's K56Flex(TM) chipsets and
requesting unspecified damages, claiming that Conexant had engaged in unfair
competition, misappropriation of trade secrets, breach of contract and breach of
confidence by using technical information allegedly disclosed in confidence by
Mr. Townshend to accelerate its development of 56 Kbps modem technology. In
January 1999, Townshend dismissed his State Court action and re-filed the same
claims and three new claims for patent infringement in the U.S. District Court
for the Northern District of California. In the Federal action, Townshend
alleges that each of his patents (the "Townshend Patents") covers certain
aspects of the V.90 standard and are infringed by Conexant's 56 Kbps products.
In the Federal action, Townshend seeks injunctive relief, compensatory damages,
restitution and exemplary and punitive damages. Townshend and 3Com Corporation
have publicly announced that 3Com is the exclusive licensee for the Townshend
Patents and acts as Townshend's agent in sublicensing the Townshend Patents to
third parties. Conexant is vigorously defending its position that it
independently developed the 56 Kbps modem technology using entirely its own
skills and public domain information and will vigorously contest the
infringement claims and the validity of the asserted patents.

Various other lawsuits, claims and proceedings have been or may be instituted or
asserted against Rockwell or Conexant or their respective subsidiaries,
including those pertaining to product liability, intellectual property,
environmental, safety and health, and employment matters. 

In connection with the Distribution, Conexant assumed responsibility for all 
contingent liabilities and current and future litigation (including 
environmental and intellectual property proceedings) against Rockwell or its 
subsidiaries in respect of Semiconductor Systems.

The outcome of litigation cannot be predicted with certainty and some lawsuits,
claims or proceedings may be disposed of unfavorably to Conexant. Many
intellectual property disputes have a risk of injunctive relief and there can be
no assurance that a license will be granted. Injunctive relief could have a
material adverse effect on the financial condition or results of operations of
Conexant. Based on its evaluation of matters which are pending or asserted and
taking into account Conexant's reserves for such matters, management of Conexant
believes the disposition of such matters will not have a material adverse effect
on the financial condition or results of operations of Conexant.

7. FINANCING AGREEMENT

On December 21, 1998, Conexant entered into a three-year secured revolving loan
facility (the Credit Facility) with a group of banks. Loans under the Credit
Facility are to be used for working capital needs and other general corporate
purposes. The Credit Facility is guaranteed by substantially all of the




                                       8
<PAGE>   9

Company's domestic subsidiaries. It is also secured by (i) a first-priority
security interest in substantially all domestic assets of the Company and its
domestic subsidiaries, and (ii) a pledge of the stock of the Company's domestic
and foreign subsidiaries, subject to certain exceptions. On January 4, 1999, the
Company borrowed $100 million under the Credit Facility, which amount remained
outstanding during the remainder of the second fiscal quarter.

Loans obtained under the Credit Facility bear interest at a rate per annum
equal, at the election of the Company, to either (i) a base rate (ABR), which is
the higher of Credit Suisse First Boston's prime rate and 0.50 percent over the
federal funds rate or (ii) the London interbank offered rate for offshore dollar
deposits (LIBOR); plus, in either case, a variable margin. For the first six
months following the Distribution, the margin is fixed at 75 basis points for
ABR-based loans and 175 basis points for LIBOR-based loans. After that, the
margin will be based on the Company's total debt to capitalization ratio. The
Company pays a facility fee on the unused amount of the Credit Facility at a per
annum rate that will vary depending on the same criteria used to determine the
interest rate margin. The Company also pays other customary fees.

The Credit Facility contains, among other terms, representations and warranties,
conditions precedent, covenants, mandatory and voluntary prepayment provisions
and events of default customary for facilities of this type. Borrowings under
the Credit Facility are limited to $250 million prior to receipt of Conexant's
1999 second fiscal quarter financial results, at which point the entire $350
million Credit Facility will be available.

8. PRO-FORMA EARNINGS (LOSS) PER SHARE

The number of pro-forma weighted average outstanding shares and common share
equivalents used in the pro-forma earnings (loss) per share calculation set
forth below was based upon the weighted average number of Rockwell shares and
share equivalents outstanding for the applicable periods, adjusted for the
distribution ratio in the Distribution of one share of the Company's common
stock for every two shares of Rockwell common stock. For the six months ended
March 31, 1999, the weighted average common shares was determined based upon the
weighted average of (i) the Rockwell method for the first fiscal quarter, as
previously described, and (ii) the actual Conexant share activity for the second
fiscal quarter, as described further in Note 9.

The pro-forma effect of common share equivalents outstanding for the three 
months ended March 31, 1998, and for the six months ended March 31, 1999, were
not included in the computation of diluted loss per share for those periods 
because the Company incurred a loss and, therefore, the impact was antidilutive.

share data):

These pro-forma results are not indicative of future amounts.

9. STOCK OPTIONS AND EARNINGS PER SHARE

The number of weighted average shares and common share equivalents outstanding
used in the earnings per share calculation for the second quarter of fiscal 1999
was based upon the weighted average number of Conexant shares outstanding and
Conexant common share equivalents for the second quarter of fiscal 1999, which
includes the Distribution of one share of the Company's common stock for every
two shares of Rockwell common stock. The common share equivalent calculation
assumes the dilutive effect of stock options to purchase 1.7 million shares of
common stock and 1.0 million shares of restricted stock which are subject to
vesting requirements.

The total stock options outstanding were 17.4 million as of March 31, 1999,
which include 9.6 million options issued in connection with the Distribution, as
well as 7.8 million options for Conexant common stock issued under the Company's
1999 Long-Term Incentives Plan (the 1999 LTIP). In connection with the
Distribution, outstanding options to purchase Rockwell common stock held by
Conexant employees, as well as certain options held by others, were converted
into options to purchase approximately 10.1 million shares of Conexant common
stock based on formulas designed to preserve the intrinsic value of the options.
The options issued in connection with the Distribution have the same terms and
vesting schedule as the original Rockwell options, and the options issued under
the 1999 LTIP generally vest over four years and expire after ten years.

At March 31, 1999, approximately 0.6 million stock options were excluded from
the calculation of diluted earnings per share, because their exercise price was
greater than the average market price of the common shares during the quarterly
period, and the effect of such inclusion would be antidilutive.

Restricted stock grants under the 1999 LTIP consist of time vesting and
performance accelerated grants. Approximately 1.0 million restricted shares are
outstanding as of March 31, 1999 under the 1999 LTIP. The time vesting
restricted stock generally will be restricted for a two-year period and will
fully vest on the second anniversary of the grant date. For the performance
accelerated restricted stock, 50 percent will vest upon the completion of twenty
consecutive trading days during which the fair market value of the stock on each
such trading day is at least 50 percent higher than the value of the stock on
the grant date, and the remaining 50 percent will vest upon the completion of
twenty consecutive trading days during which the fair market value of the stock
on each such trading day is at least 100 percent higher than the value of the
stock on the grant date, provided that no performance accelerated restricted
stock will vest prior to one year after the date of grant. In any event, the
performance accelerated restricted stock will fully vest on the eighth
anniversary of the grant date.

Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," allows companies to record compensation cost for stock-based
employee compensation plans at fair value or to show the effects in a footnote.
The Company has chosen to account for stock-based compensation using the
intrinsic value method prescribed in Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related Interpretations.
Accordingly, compensation cost of stock options is measured as the excess, if
any, of the quoted market price of the Company's stock at the date of the grant
over the option exercise price, and is charged to operations over the vesting
period. Income tax benefits attributable to stock options exercised will be
credited to capital in excess of par value at the end of the fiscal year. As of
March 31, 1999, all stock options granted to employees were granted at an
exercise price equal to the closing market price of the stock on the date of
grant; therefore, no expense to the Company has been incurred. No compensation
expense has been 


                                       10
<PAGE>   11

recognized for any other stock-based incentive compensation plans, other than
$2.3 million related to the restricted stock awards. The Company expects to
grant additional stock-based compensation awards in future years.


Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

This information should be read in conjunction with the unaudited consolidated
condensed financial statements and the notes thereto included in Part I, Item 1
of this Quarterly Report, and the audited combined financial statements and
notes thereto and Management's Discussion and Analysis of Financial Condition
and Results of Operations contained in the Company's Registration Statement on
Form 10.

The results of operations for the periods prior to January 1, 1999 reflect the
Company's operations as a subsidiary of Rockwell. The results of operations
subsequent to December 31, 1998 reflect the Company's operations as a
stand-alone entity subsequent to the spin-off from Rockwell. The results of
operations while the Company was a subsidiary of Rockwell may not be indicative
of the results of operations of the Company if it had been a stand-alone entity
for the time periods shown herein.

RESULTS OF OPERATIONS


The following table summarizes the net sales of the Company's five product
platforms for the periods presented (dollars are in thousands and percentages
are expressed as a percentage of total net sales):

NET SALES: Net sales of $316.9 million in the second fiscal quarter (Q2) of 1999
were $42.7 million, or 16%, higher than Q2 of 1998 on a 68% increase in unit
shipments. This increase was primarily due to revenue growth in three of the
Company's operating platforms. Net sales for Wireless Communications increased
71% with record shipments of power amplifiers for cellular phones and strong
demand for other products, including cellular base station receivers, wireless
data, and global positioning systems (GPS). Code Division Multiple Access (CDMA)
power amplifier net sales increased 171% from the prior year, generating more
than 63% of Q2 1999 Wireless Communications revenue. Net sales for Network
Access increased 65%, primarily associated with an inventory correction at one
customer in Q2 1998 for K56 central site modems. Network Access had record
sales of all high-speed digital-networking products that include synchronous
optical network (SONET), T1/E1, digital subscriber line (DSL) solutions, and
asynchronous transfer mode (ATM). Net sales for Digital Infotainment increased
17%. This performance was driven by solid growth in both the consumer and
computer market segments, including satellite set-top box tuners and
demodulators, video encoders, and peripheral computer interconnect (PCI)
decoders for PC-TV applications. Net sales were adversely affected by a decline
in average selling prices, which partially offset the increase in unit shipments
for the three expansion platforms just discussed. Personal

Computing revenues declined as a percentage of total sales from 54% in Q2 1998
to 47% in Q2 1999 but remained essentially flat in terms of revenue dollars as
pricing returned to historical patterns. Personal Imaging sales decreased 23%
primarily due to a reduction in facsimile modem shipments to the Asian market.

For the six months ended March 31, 1999, net sales of $611.6 million were 7%
less than net sales of $657.7 million for the six months ended March 31, 1998,
on a 34% increase in unit shipments. Net sales declined in two of the five
product platforms during the six months ended March 31, 1999 compared to the
same period in fiscal 1998. Net sales for Personal Computing decreased 21%.
Personal Computing sales comprised 49% of the Company's net sales compared to
58% for the same period in the previous year. Net sales declined due to a shift
towards lower priced products such as the Host Controllerless (HCF) product line
and a decline in average selling prices. Net sales for Personal Imaging declined
38%. This decrease was primarily related to a reduction in facsimile modem
shipments to the Asian market. The decline in net sales from Personal Computing
and Personal Imaging compared to the first six months of fiscal 1998 were
partially offset by unit shipment and revenue growth in the other three product
platforms. Net sales for Wireless Communications increased from $76.5 million to
$102.3 million, or 34%. This growth was due primarily to the CDMA power
amplifier product line. Net sales for Network Access increased from $62.5
million to $88.7 million, or 42%. Net sales for Digital Infotainment increased
from $77.5 million to $82.1 million, or 6%, and was driven by increased
shipments of encoder/decoder products and set-top box tuners.

GROSS MARGIN: Gross margin increased 7% to $130.3 million in Q2 1999 from $121.6
million in Q2 1998. As a percentage of net sales, gross margin decreased to 41%
from 44% in Q2 1998 due to lower prices for Personal Computing products, which
eroded faster than associated unit production costs. For the six months ended
March 31, 1999, gross margin decreased 31% to $208.2 million, from $301.7
million for the six months ended March 31, 1998. As a percentage of net sales,
gross margin decreased to 34% from 46% in the same period of the prior year,
primarily due to pricing pressure in Personal Computing and unusually high
inventory costs associated with lower manufacturing capacity utilization in the
first fiscal quarter of 1999.

RESEARCH AND DEVELOPMENT: Research and development (R&D) expenses in Q2 1999 of
$68.8 million were $11.8 million, or 14.7%, lower than in Q2 1998. R&D expenses
for the six months ended March 31, 1999 were $ 139.9 million, 14.8% lower than
the $164.2 million in the six months ended March 31, 1998. The decrease in R&D
for the fiscal 1999 periods was driven principally by cost reduction actions
initiated in the fourth quarter of fiscal 1998 to reduce the Company's overall
cost structure. These actions included headcount reductions, design center
closures and project cancellations.

SELLING, GENERAL, AND ADMINISTRATIVE: Selling, general, and administrative
(SG&A) expenses in Q2 1999 of $48.9 million were $19.9 million, or 29%, lower
than in Q2 1998. SG&A expenses for the six months ended March 31, 1999 were
$112.9 million, 12% lower than the $128.4 million for the same period of the
prior year. The decline for both periods was due to reductions in headcount,
advertising and consulting expenses.

AMORTIZATION OF INTANGIBLES: Amortization of intangibles in Q2 1999 of $2.1
million was $0.7 million, or 25.5%, lower than in Q2 1998. Amortization of
intangibles for the six months ended March 31, 1999 was $4.1 million, 27%
lower than the $5.6 million for the same period of the prior year. The decline
for both periods was due to a write-off of goodwill related to the acquisition
of certain technologies that were abandoned in Q4 1998 in conjunction with the
restructuring activities.

SPECIAL CHARGES - ROCKWELL RETAINED ASSETS: In the first fiscal quarter of 1999,
Conexant recorded a special charge for an additional asset impairment of $20
million for the Colorado Springs wafer fabrication facilities as a result of
Rockwell's decision to further write-down the facilities, which were retained by
Rockwell as part of the spin-off. This non-cash charge was required to be
reported in the Company's last fiscal quarter as a subsidiary of Rockwell.

SPECIAL CHARGES - OTHER: Other special charges for the first quarter of fiscal
1999 and the six months ended March 31, 1999 were $17.9 million. These special
charges included approximately $17 million related to a voluntary early
retirement program and $1 million related to equipment decommission and contract
cancellation at the Colorado Springs wafer fabrication facility.

OTHER INCOME, NET: Other income decreased to $0.4 million in Q2 1999 from $1.9
million in Q2 1998 primarily due to $1.7 million of interest on the Company's
$100 million of short-term debt in Q2 1999. Other income for the six month
period ended March 31, 1999 of $0.2 million decreased from $5.7 million in the
first six months of fiscal 1998 primarily due to a $3.3 million cash payment
that was received in the first fiscal quarter (Q1) 1998 in connection with a
contract cancellation as well as the interest expense of $1.7 million recorded
in the six months ended March 31, 1999.

PROVISION (BENEFIT) FOR INCOME TAXES: The income tax provision in the second
quarter of fiscal 1999 was $3.2 million, or 30% of income before income taxes.
In the second fiscal quarter of fiscal 1998, an income tax benefit of $13
million was recorded due to a loss from operations. The income tax provision for
the six months ended March 31, 1999 was a benefit of $36.9 million, or 43% of
loss before income taxes. For the six months ended March 31, 1998, an income tax
provision of $4.1 million, or 46% of income before income taxes, was provided.
The effective tax rate for the remainder of the fiscal year is expected to
remain at 30%, down from earlier quarters, primarily due to the positive impact
of various tax credits available to the Company. The effective tax rate includes
state tax credits and federal research and experimentation tax credits.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities was $133.9 million for the six months
ended March 31, 1999, compared to $8.3 million of cash used by operating
activities in the same period of fiscal 1998. Net operating cash flows were
favorably impacted due to a net decrease in inventories of $54.3 million in the
first six months of fiscal 1999, as compared to a net increase of $86.7 million
in the prior year, reflecting the results of the Company's efforts to reduce
inventory quantities and unit costs. In addition, net receivables were reduced
by $20.4 million during the six months ended March 31, 1999, driven by an
improved rate of collections. Net income in the first six months of fiscal 1999
was reduced by non-cash special charges of $37.9 million and non-cash charges
for depreciation and amortization of $104.2 million. These items were partially
offset by a $21.7 million decrease in trade payables and a $16.8 million
decrease in other current liabilities from September 30, 1998.

Investing activities used $33.4 million in cash during the six months ended
March 31, 1999, compared to $122.5 million in the same period of 1998. Lower
current period investments relate to the timing of capital expenditures for
additional capacity and new process technologies. Capital expenditures for the
entire 1999 fiscal year are expected to be approximately $160 million.

The Company's financing activities provided cash of $44.6 million during the six
months ended March 31, 1999, compared to $130.8 million during the same period
of fiscal 1998. Financing sources of cash for the first six months of fiscal
1999 were $100 million of short-term borrowings under a three-year $350 million
senior secured revolving loan facility (the Credit Facility). These items were
partially offset by the repayment of a loan 


                                       13
<PAGE>   14

at the Company's Japanese subsidiary and net transfers to Rockwell. In fiscal
1998, the financing sources of cash were predominantly transfers of cash from
Rockwell.

In December 1998, the Company and three of its subsidiaries entered into the
Credit Facility with a group of banks. The Credit Facility includes facilities
for revolving loans and swingline loans in multiple currencies and letters of
credit. The Credit Facility is guaranteed by substantially all of the Company's
domestic subsidiaries. It is also secured by (i) a first-priority security
interest in substantially all domestic assets of the Company and its domestic
subsidiaries and (ii) a pledge of the stock of the Company's domestic and
foreign subsidiaries, subject to certain exceptions. See Note 7 of the notes to
unaudited consolidated condensed financial statements for further details on the
Credit Facility.

The Credit Facility contains, among other terms, representations and warranties,
conditions precedent, covenants, mandatory and voluntary prepayment provisions
and events of default customary for facilities of this type. Covenants include
certain restrictions on capital expenditures, consolidations and mergers, sales
of assets, incurrence of indebtedness and creation of liens and encumbrances.
The Credit Facility includes various financial covenants, including a minimum
net worth requirement and required financial ratios in respect of (i) earnings
before interest, taxes, depreciation and amortization (EBITDA) to interest
expense, (ii) debt to EBITDA and (iii) cash, cash equivalents and net accounts
receivable classified as current assets to current liabilities.

On January 4, 1999, the Company borrowed $100 million under the Credit Facility.
The Company invests its excess cash balances in short-term interest bearing
accounts.

The Company believes that its existing sources of liquidity and cash expected to
be generated from future operations are sufficient to fund operations, capital
expenditures and research and development efforts for the foreseeable future.

YEAR 2000 READINESS DISCLOSURE

Conexant is addressing the impact of the Year 2000 on each of five major areas:
the Company's products, business systems (computer systems that handle business
processes), infrastructure (servers, desktop computers, networks, telecom
systems and software), manufacturing systems (computer systems used in the
manufacturing process) and suppliers (critical materials suppliers to the
business). Each of the five areas is undergoing the following process to ensure
readiness for the Year 2000. First, in the inventory phase, all Conexant assets
are inventoried to identify those that have any type of software or hardware
with Year 2000-related issues. Second, in the assessment phase, all inventoried
items are assessed to confirm that a Year 2000-related issue is present and the
extent of remediation required. Third, in the strategy phase, a remediation
strategy is created to ensure that all critical systems are upgraded to be Year
2000 ready by December 31, 1999. Fourth, in the conversion/upgrade phase,
upgrades are performed on all items identified in the assessment and strategy
phases. Finally, in the certification phase, all upgraded items receive final
certification testing to verify Year 2000 readiness. Conexant has completed the
inventory phase for all five areas. In addition, it has completed the assessment
and strategy phases and is currently in the conversion and certification phases
for the products, business systems, infrastructure, and manufacturing systems
areas. The Company has completed the assessment and strategy phase and is now
in the remediation and certification phases for the suppliers area. The Company
has begun auditing those suppliers who did not perform up to standards during
the assessment phase. Conexant is integrating its testing efforts with SEMATECH,
a consortium of semiconductor manufacturing companies, to ensure best practice
testing. The manufacturing systems, hardware systems and software applications
areas are being tested under the SEMATECH guidelines.

                                       14
<PAGE>   15

The Company's greatest area of uncertainty centers primarily in the supplier
area, due to the number of equipment and materials suppliers involved and their
various stages of readiness for Year 2000. In particular, the Company is
dependent on suppliers to upgrade their systems to ensure an uninterrupted
supply of materials. Approximately 85 percent of our manufacturing tools have
achieved certification. A Year 2000-related failure by a significant materials
supplier could result in the temporary slowdown of production by the Company,
the duration of which the Company reasonably estimates would be not more than a
few days. As a result, the Company's contingency plan centers heavily on the
supplier area. For the top five to ten percent of its critical materials and
manufacturing suppliers, the Company is performing on-site audits and intends to
monitor specific Year 2000-based milestones to ensure readiness. The Company has
completed its assessment of all Tier 1 critical suppliers and has begun its
audit process. In the event a supplier does not meet the Company's milestones
for Year 2000 readiness, the Company is identifying specific target dates
(beginning as early as April 1999) for all critical materials suppliers and has
begun implementing a contingency plan that includes alternate sourcing and
stockpiling of materials, which the Company expects will be complete by June 30,
1999.

Part of the Company's initial assessment phase included a detailed Year 2000
questionnaire which was sent to all critical materials and manufacturing
suppliers. This questionnaire included questions on products, services, internal
operating systems, and the supplier's own supply chain. To date, the Company has
received responses from all of those questioned. The Company is following up on
the questionnaires, where necessary, with on-site audits to ensure Year 2000
readiness. The Company has also contacted its major customers with respect to
their Year 2000 readiness efforts and does not believe that customers will have
any Year 2000 readiness problems that would have a material adverse effect on
the Company's business.

In connection with the Company's receipt of transition services pursuant to the
transition agreement with Rockwell, the Company is relying on certain of
Rockwell's computer systems, including its payroll and benefits administration
systems, for a period of up to two years after the Distribution. The Company
believes that the Rockwell systems on which it relies for transition services
will be Year 2000 ready, such that its reliance thereon will not have a material
adverse effect on the Company's financial position or results of operations.

Overall, utilizing both internal and external resources to address the Year 2000
issue, Conexant has achieved a certification level of 80 percent as of March 31,
1999 and plans to be 100 percent complete by June 30, 1999. The current estimate
of total project cost is approximately $6 million, which includes the cost of
purchasing certain hardware and software. Approximately $5 million of this
amount is for capital investments, with the remainder being expenses (primarily
salary costs). As of March 31, 1999, approximately $2.3 million had been spent,
with the majority of the remaining amount to be spent by the end of this fiscal
year. Conexant continues to evaluate the estimated costs associated with these
efforts based on actual experience. Management believes, based on available
information, that the Company will be able to remediate Year 2000-related issues
in the products, business systems, and infrastructure areas without any material
adverse effect on its business operations, products, or financial condition.
However, the Company could be adversely impacted by the Year 2000 issues faced
by major suppliers, distributors, customers, vendors, and financial services
organizations with which the Company interacts. Any disruption in the Company's
operations as a result of the failure of any of these third parties to be Year
2000 ready could have a material adverse effect on Conexant's business
operations, products, and financial condition.

                                       15

The Company has begun initial preparation of a Year 2000 contingency plan for
the entire Company, with an expectation to complete this plan by September 1999.

CAUTIONARY STATEMENT

This Quarterly Report contains statements relating to future results of the
Company (including certain projections and business trends) that are
"forward-looking statements" as defined in the Private Securities Litigation
Reform Act of 1995. Actual results may differ materially from those projected as
a result of certain risks and uncertainties. These risks and uncertainties
include, but are not limited to: global and market conditions, including, but
not limited to, the cyclical nature of the semiconductor industry and the
markets addressed by the Company's and its customers' products; demand for, and
market acceptance of, new and existing products; successful development of new
products; the timing of new product introductions; the availability and extent
of utilization of manufacturing capacity and raw materials; pricing pressures
and other competitive factors; changes in product mix; fluctuations in
manufacturing yields; product obsolescence; the ability to develop and implement
new technologies and to obtain protection of the related intellectual property;
the successful implementation of the Company's diversification strategy and
restructuring plan; labor relations of the Company, its customers and suppliers;
timely completion of Year 2000 modifications by the Company and its key
suppliers and customers; and the uncertainties of litigation, as well as other
risks and uncertainties, including but not limited to those discussed in the
Company's Registration Statement on Form 10 or detailed from time to time in the
Company's Securities and Exchange Commission filings. Reference is made to the
Risk Factors section on pages 12 to 21 of the Information Statement included in
the Company's Registration Statement on Form 10. These forward-looking
statements are made only as of the date hereof, and the Company undertakes no
obligation to update or revise the forward-looking statements, whether as a
result of new information, future events or otherwise.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's financial instruments include cash and short-term debt. At March
31, 1999, the carrying values of the Company's financial instruments
approximated their fair values based on current market prices and rates.

It is the policy of the Company not to enter into derivative financial
instruments for speculative purposes. The Company enters into foreign currency
forward exchange contracts to protect itself from adverse currency rate
fluctuations on foreign currency commitments entered into in the ordinary course
of business. These commitments are generally for terms of less than one year.
The foreign currency forward exchange contracts are executed with creditworthy
banks and are denominated in currencies of major industrial countries. The
notional amount of all the Company's outstanding foreign currency forward
exchange contracts aggregated $14.3 million at March 31, 1999, and $17 million
at September 30, 1998. The gains and losses relating to these foreign currency
forward exchange contracts are deferred and included in the measurement of the
foreign currency transaction subject to the hedge. The Company believes that any
gain or loss incurred on foreign currency forward exchange contracts is offset
by the effects of currency movements on the respective underlying hedged
transactions.

Based on the Company's overall currency rate exposure at March 31, 1999, a 10
percent change in currency rates would not have had a material effect on the
financial position, results of operations or cash flows of the Company.

PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

On September 27, 1995, Celeritas Technologies, Ltd. filed a suit against
Rockwell in the U.S. District Court for the Central District of California for
patent infringement, misappropriation of trade secrets and breach of contract
relating to cellular telephone data transmission technology utilized in certain
modem products produced by Conexant in 1995 and 1996. The court entered judgment
against Rockwell in January 1997 and, in ruling on post-trial motions in July
1997, entered a revised judgment awarding damages of $57 million, plus interest.
On July 20, 1998, the U.S. Court of Appeals for the Federal Circuit reversed the
holding of the trial court based on patent infringement and found Celeritas's
patent invalid but affirmed the trial court holding based on breach of contract.
Conexant's petition for a rehearing (and rehearing en banc) and a motion to
certify the contract issue to the California Supreme Court were denied in
September 1998. Conexant's petition for certiorari with the United States
Supreme Court filed on November 23, 1998 was denied in January 1999. Conexant
has received a satisfaction of judgment from the court for the $65 million,
previously accrued for the ultimate resolution of this matter, used to satisfy
Conexant's obligation with respect to this matter.

Conexant was joined on April 7, 1998 as a defendant in a suit filed by Harris
Corporation against PairGain Technologies, Inc. in the Superior Court of
California for Orange County. Harris alleges that a "teaming agreement" between
it and PairGain to develop a complete ADSL solution constituted a joint venture
and that Conexant's subsequent exclusive agreement with PairGain to develop
digital modem products using PairGain's ADSL technology constituted an
intentional interference with contractual relations, intentional interference
with prospective economic advantage, negligent interference with contractual
relations and an unfair trade practice in violation of the California Business &
Professions Code. As of November 3, 1998, Conexant settled its portion of the
lawsuit.

On October 14, 1997, Brent Townshend filed suit against Rockwell and Conexant in
the Superior Court of California for San Mateo County seeking an injunction to
halt the sale of products containing Conexant's K56Flex(TM) chipsets and
requesting unspecified damages, claiming that Conexant had engaged in unfair
competition, misappropriation of trade secrets, breach of contract and breach of
confidence by using technical information allegedly disclosed in confidence by
Mr. Townshend to accelerate its development of 56 Kbps modem technology. In
January 1999, Townshend dismissed his State Court action and re-filed the same
claims and three new claims for patent infringement in the U.S. District Court
for the Northern District of California. In the Federal action, Townshend
alleges that each of his patents (the "Townshend Patents") covers certain
aspects of the V.90 standard and are infringed by Conexant's 56 Kbps products.
In the Federal action, Townshend seeks injunctive relief, compensatory damages,
restitution and exemplary and punitive damages. Townshend and 3Com Corporation
have publicly announced that 3Com is the exclusive licensee for the Townshend
Patents and acts as Townshend's agent in sublicensing the Townshend Patents to
third parties. Conexant is vigorously defending its position that it
independently developed the 56 Kbps modem technology using entirely its own
skills and public domain information and will vigorously contest the
infringement claims and the validity of the asserted patents.

On July 29, 1991, Shumpei Yamazaki filed suit against a Japanese subsidiary of
Rockwell in the Tokyo District Court, Twenty-ninth Civil Division for patent
infringement relating to Conexant's facsimile modem chipsets seeking 685 million
yen (approximately $5.74 million based on the exchange rate on April 28, 1999)
and court costs. In October 1998, the District Court rendered its decision
dismissing the suit, from which decision Mr. Yamazaki appealed. On April 12,
1999, Mr. Yamazaki presented his position at the first portion of the appellate
hearing. Conexant will present its position to the appellate court on June 16,
1999. Conexant believes it has meritorious defenses to these claims and will
vigorously defend this action.

On May 30, 1997, Klaus Holtz filed suit against Rockwell in the U.S. District
Court for the Northern District of California for patent infringement relating
to Conexant's modem products utilizing the 


                                       17
<PAGE>   18

V.42bis standard for data compression. On September 30, 1998, the Court barred
any alleged damages arising before May 30, 1997. On December 17, 1998, the Court
issued an order construing the claims of the patent. Conexant filed a motion for
Summary Judgment of Non-Infringement on February 22, 1999, and expects a hearing
thereon in June 1999. Conexant believes it has meritorious defenses to these
claims and will vigorously defend this action.

Conexant conducts its business in market sectors where the Lemelson Foundation
broadly asserts certain intellectual property rights against all participants.
The Lemelson Foundation has made explicit demands that virtually all
semiconductor companies must be licensed under those intellectual property
rights and must pay the Foundation a royalty calculated as a percentage of
product sales. The Lemelson Foundation filed a patent infringement suit in the
U.S. District Court in Arizona against approximately 88 defendants from the
semiconductor industry, including Rockwell and Conexant. Rockwell and Conexant
are in the process of negotiating a license under the Lemelson patent portfolio.
It is Conexant's position that a portion of any royalty Conexant would be
obligated to pay under such license should be indemnified by certain vendors to
Conexant.

Various other lawsuits, claims and proceedings have been or may be instituted or
asserted against Rockwell or Conexant or their respective subsidiaries,
including those pertaining to product liability, intellectual property,
environmental, safety and health, and employment matters.

In connection with the Distribution, Conexant assumed responsibility for all
current and future litigation (including environmental and intellectual property
proceedings) against Rockwell or its subsidiaries in respect of Semiconductor
Systems.

The outcome of litigation cannot be predicted with certainty and some lawsuits,
claims or proceedings may be disposed of unfavorably to Conexant  Many
intellectual property disputes have a risk of injunctive relief and there can be
no assurance that a license will be granted. Injunctive relief could have a
material adverse effect on the financial condition or results of operations of
Conexant. Based on its evaluation of matters which are pending or asserted and
taking into account Conexant's reserves for such matters, management of Conexant
believes the disposition of such matters will not have a material adverse effect
on the financial condition or results of operations of Conexant.
