1. COMPANY BACKGROUND

     General Instrument Corporation ("General Instrument" or the "Company"),
formerly NextLevel Systems, Inc., is a leading worldwide provider of integrated
and interactive broadband access solutions and, with its strategic partners and
customers, is advancing the convergence of the Internet, telecommunications and
video entertainment industries. The Company is the world's leading supplier of
digital and analog set-top terminals and systems for wired and wireless cable
television networks, as well as hybrid fiber/coaxial network transmission
systems used by cable television operators, and is a provider of digital
satellite television systems for programmers, direct-to-home ("DTH") satellite
networks and private networks for business communications. Through its limited
partnership interest in Next Level Communications L.P. (the "Partnership") and
its interest in the Partnership's successor, Next Level Communication, Inc.,
(see Notes 10 and 14), the Company provides next-generation broadband access
solutions for local telephone companies with the NLevel3(R) Switched Digital
Access System ("NLevel3").

     The Company was formerly the Communications Business of the former General
Instrument Corporation (the "Distributing Company"). In a transaction that was
consummated on July 28, 1997, the Distributing Company (i) transferred all the
assets and liabilities, at the Distributing Company's historical cost, relating
to the manufacture and sale of broadband communications products used in the
cable television, satellite, and telecommunications industries to the Company
(then a wholly-owned subsidiary of the Distributing Company) and all the assets
and liabilities relating to the manufacture and sale of coaxial, fiber optic and
other electric cable used in the cable television, satellite and other
industries to its wholly-owned subsidiary CommScope, Inc. ("CommScope"), at the
Distributing Company's historical cost, and (ii) distributed all of its
outstanding shares of capital stock of each of the Company and CommScope to its
stockholders on a pro rata basis as a dividend. Approximately 147.3 million
shares of the Company's common stock, par value $.01 per share (the "Common
Stock"), based on a ratio of one for one, were distributed to the Distributing
Company's stockholders of record on July 25, 1997 (the "Communications
Distribution"). On July 28, 1997, approximately 49.1 million shares of CommScope
common stock, based on a ratio of one for three, were distributed to the
Company's stockholders of record on that date (the "CommScope Distribution" and,
together with the Communications Distribution, the "Distribution"). On July 28,
1997, the Company and CommScope began operating as independent entities with
publicly traded common stock, and the Distributing Company retained no ownership
interest in either the Company or CommScope. Additionally, immediately following
the Communications Distribution, the Distributing Company was renamed General
Semiconductor, Inc. ("General Semiconductor") and effected a one for four
reverse stock split.

    In September, 1999, the Company entered into a definitive agreement of
merger with Motorola, Inc. and its wholly-owned subsidiary, Lucerne Acquisition
Corp. Under the merger agreement, which is subject to customary regulatory and
stockholder approvals, each share of the Company would be exchanged for 0.575
shares of Motorola, Inc.

2. BASIS OF PRESENTATION

    The accompanying interim consolidated financial statements reflect the
results of operations, financial position, changes in stockholders' equity and
cash flows of the Company. The consolidated balance sheet as of September 30,
1999, the consolidated statements of operations for the three and nine months
ended September 30, 1999 and 1998, the consolidated statement of stockholders'
equity for the nine months ended September 30, 1999 and the consolidated
statements of cash flows for the nine months ended September 30, 1999 and 1998
of the Company are unaudited and reflect all adjustments of a normal, recurring
nature (except for those charges disclosed in Notes 7, 8 and 10) which are, in
the opinion of management, necessary for a fair presentation of the interim
period financial statements. The results of operations for the interim period

5. COMMITMENTS AND CONTINGENCIES

    A securities class action is presently pending in the United States District
Court for the Northern District of Illinois, Eastern Division, In Re General
Instrument Corporation Securities Litigation. This action, which consolidates
numerous class action complaints filed in various courts between October 10 and
October 27, 1995, is brought by plaintiffs, on their own behalf and as
representatives of a class of purchasers of the Distributing Company's common
stock during the period March 21, 1995 through October 18, 1995. The complaint
alleges that the Distributing Company and certain of its officers and directors,
as well as Forstmann Little & Co. and certain related entities, violated the
federal securities laws, namely, Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), prior to the
Distribution, by allegedly making false and misleading statements and failing to
disclose material facts about the Distributing Company's planned shipments in
1995 of its CFT2200 and Digicipher(R) products. Also pending in the same court,
under the same name, is a derivative action brought on behalf of the
Distributing Company. The derivative action alleges that, prior to the
Distribution, the members of the Distributing Company's Board of Directors,
several of its officers and Forstmann Little & Co. and related entities have
breached their fiduciary duties by reason of the matter complained of in the
class action and certain defendants' alleged use of material non-public
information to sell shares of the Distributing Company's stock for personal
gain. Both actions seek unspecified damages and attorneys' fees and costs. The
court granted the defendants' motion to dismiss the original complaints in both
of these actions, but allowed the plaintiffs in each action an opportunity to
file amended complaints. Amended complaints were filed on November 7, 1997. The
defendants answered the amended consolidated complaint in the class actions,
denying liability, and filed a renewed motion to dismiss the derivative action.
On September 22, 1998, defendants' motion to dismiss the derivative action was
denied. In November 1998, the defendants filed an answer to the derivative
action, denying liability. On January 21, 1999, the plaintiffs in the class
actions filed their motion for class certification, including the defendants'
opposition. No ruling has been made on the class certification issue. The
Company intends to vigorously contest these actions.

    An action entitled BKP Partners, L.P. v. General Instrument Corp. was
brought in February 1996 by certain holders of preferred stock of Next Level
Communications ("NLC"), which merged into a subsidiary of the Distributing
Company in September 1995. The action was originally filed in the Northern
District of California and was subsequently transferred to


                                       8

                     (IN THOUSANDS, UNLESS OTHERWISE NOTED)

the Northern District of Illinois. The plaintiffs allege that the defendants
violated federal securities laws by making misrepresentations and omissions and
breached fiduciary duties to NLC in connection with the acquisition of NLC by
the Distributing Company. Plaintiffs seek, among other things, unspecified
compensatory and punitive damages and attorneys' fees and costs. On September
23, 1997, the district court dismissed the complaint, without prejudice, and the
plaintiffs were given until November 7, 1997 to amend their complaint. On
November 7, 1997, plaintiffs served the defendants with an amended complaint,
which contains allegations substantially similar to those in the original
complaint. The defendants filed a motion to dismiss parts of the amended
complaint and answered the balance of the amended complaint, denying liability.
On September 22, 1998, the district court dismissed with prejudice the portion
of the complaint alleging violations of Section 14(a) of the Exchange Act, and
denied the remainder of the defendants' motion to dismiss. In November, 1998,
the defendants filed an answer to the remaining parts of the amended complaint,
denying liability. The Company intends to vigorously contest this action.

    In connection with the Distribution, the Company has agreed to indemnify
General Semiconductor with respect to its obligations, if any, arising out of or
in connection with the matters discussed in the preceding two paragraphs.

    On February 19, 1998, a consolidated securities class action complaint
entitled In Re Nextlevel Systems, Inc. Securities Litigation was filed in the
United States District Court for the Northern District of Illinois, Eastern
Division, naming the Company and certain former officers and directors as
defendants. The complaint was filed on behalf of stockholders who purchased or
otherwise acquired stock of the Company between July 25, 1997 and October 15,
1997. The complaint alleged that the defendants violated Sections 11 and 15 of
the Securities Act of 1933, as amended (the "Securities Act"), and Sections
10(b) and 20(a) of the Exchange Act and Rule 10b-5 thereunder by making false
and misleading statements about the Company's business, finances and future
prospects. The complaint seeks damages in an unspecified amount. On April 9,
1998, the plaintiffs voluntarily dismissed their Securities Act claims. On May
5, 1998, the defendants moved to dismiss the remaining counts of the complaint.
That motion was denied on March 31, 1999 and defendants' answer was filed on
June 25, 1999. On July 30, 1999, defendants filed a motion seeking
reconsideration of the denial of their motion to dismiss. The Company intends to
vigorously contest this action.

    On March 5, 1998, an action entitled DSC Communications Corporation and DSC
Technologies Corporation v. Next Level Communications L.P., KK Manager, L.L.C.,
General Instrument Corporation and Spencer Trask & Co., Inc. was filed in the
Superior Court of the State of Delaware in and for New Castle County (the
"Delaware Action"). In that action, DSC Communications Corporation and DSC
Technologies Corporation (collectively, "DSC") alleged that in connection with
the formation of the Partnership and the transfer to it of NLC's switched
digital video technology, the Partnership and KK Manager, L.L.C. misappropriated
DSC's trade secrets; that the Company improperly disclosed trade secrets when it
conveyed such technology to the Partnership; and that Spencer Trask & Co., Inc.
conspired to misappropriate DSC's trade secrets. The plaintiffs sought actual
damages for the defendants' purported unjust enrichment, disgorgement of
consideration, exemplary damages and attorney's fees, all in unspecified
amounts. In April 1998, the Company and the other defendants filed an action in
the United States District Court for the Eastern District of Texas, requesting
that the federal court preliminarily and permanently enjoin DSC from prosecuting
the Delaware Action because by pursuing such action, DSC effectively was trying
to circumvent and relitigate the Texas federal court's November 1997 judgment in
a previous lawsuit involving DSC, pursuant to which NLC had paid over $140
million. On May 14, 1998, the Texas court granted a preliminary injunction
preventing DSC from proceeding with the Delaware Action. That injunction order
was appealed to the United States Court of Appeals for the Fifth Circuit. On
June 21, 1999, the Fifth Circuit affirmed the Texas federal court's grant of the
preliminary injunction. On July 15, 1999, the Texas federal court granted the
Delaware defendants' motion for summary judgment and issued its final judgment
permanently enjoining DSC from prosecuting and continuing the Delaware Action.

    In May 1997, StarSight Telecast, Inc. ("StarSight") filed a Demand for
Arbitration against the Company alleging that the Company breached the terms of
a license agreement with StarSight by (a) developing a competing product that
wrongfully incorporates StarSight's technology and inventions claimed within a
certain StarSight patent, (b) failing to promote and market the StarSight
product as required by the license agreement, and (c) wrongfully using
StarSight's technical information, confidential information and StarSight's
graphical user interface in breach of the license agreement. StarSight sought
injunctive relief as well as damages. The first part of a bifurcated arbitration
proceeding, relating to the Company's advanced analog products, began on March
22, 1999 before an arbitration panel of the American Arbitration Association in
San Francisco, California. Oral arguments to the panel by the Company and
StarSight were concluded on May 23, 1999. On October 4, 1999, the arbitration
panel released an interim decision with respect to advanced analog products
only. The arbitration panel found that the Company had breached the license
agreement and had misappropriated certain StarSight trade secrets relating to
electronic program guides. The arbitration panel rejected StarSight's
interpretation of its patents and also


                                       9
<PAGE>   10
                         GENERAL INSTRUMENT CORPORATION
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                     (IN THOUSANDS, UNLESS OTHERWISE NOTED)

found that the Company did not commercialize products that incorporate those
patents. The panel further denied StarSight's request for an injunction. The
arbitration panel found that StarSight is entitled to compensatory and punitive
damages. The amount of such damages will be finally determined by the
arbitrators based on damage calculations submitted by the parties. The Company
estimates that compensatory damages will be in the range of $25 to $36 million.
An additional 50% of such amount will be added as punitive damages, plus
attorneys fees and costs. General Instrument has not determined whether it will
oppose confirmation of the damage award. A separate phase of the arbitration
relating to the use of electronic program guides on digital cable set-top
terminals and satellite receivers is not anticipated to be scheduled until the
second quarter of 2000. Unlike its advanced analog products, the Company does
not sell a Company electronic program guide with its digital cable set-top
terminals. The Company denies StarSight's allegations in the second phase and
will continue to vigorously contest this action.

    On November 30, 1998, an action entitled Gemstar Development Corporation and
Index Systems, Inc. v. General Instrument Corporation was filed in the United
States District Court for the Northern District of California. The complaint
alleges infringement by the Company of two U.S. patents allegedly covering
electronic program guides. The complaint seeks unspecified damages and an
injunction. After filing this action, the plaintiffs sought to consolidate
discovery for this action with other program guide related patent infringement
actions pending against Pioneer Electronics Corp., Scientific-Atlanta, Inc., and
Prevue Networks, Inc. On April 26, 1999, the Judicial Panel on Multidistrict
Litigation ordered the transfer of this action to the Northern District of
Georgia for consolidated pretrial proceedings with the Pioneer Electronics Corp.
and Scientific-Atlanta, Inc. actions. Scheduling and other preliminary discovery
matters are currently awaiting an order from the Court. The Company denies that
it infringes the subject patents and intends to vigorously defend this action.

6. LONG-TERM DEBT

    In July 1997, the Company entered into a bank credit agreement (the "Credit
Agreement") which provides a $600 million unsecured revolving credit facility
and matures on December 31, 2002. The Credit Agreement permits the Company to
choose between two interest rate options: an Adjusted Base Rate (as defined in
the Credit Agreement), which is based on the highest of (i) the rate of interest
publicly announced by The Chase Manhattan Bank as its prime rate, (ii) 1% per
annum above the secondary market rate for three-month certificates of deposit
and (iii) the federal funds effective rate from time to time plus 0.5%, and a
Eurodollar rate (LIBOR) plus a margin which varies based on certain performance
criteria. The Company is also able to set interest rates through a competitive
bid procedure. In addition, the Credit Agreement requires the Company to pay a
facility fee on the total loan commitment. The Credit Agreement contains
financial and operating covenants, including limitations on guarantee
obligations, liens and sale of assets, and requires the maintenance of certain
financial ratios. Significant financial ratios include (i) maintenance of
consolidated net worth above $600 million adjusted for 50% of cumulative
positive quarterly net income subsequent to June 30, 1997; (ii) maintenance of
an interest coverage ratio based on EBITDA in comparison to net interest expense
of greater than 5 to 1; and (iii) maintenance of a leverage ratio comparing
total indebtedness to EBITDA of less than 3 to 1. In addition, under the Credit
Agreement, certain changes in control of the Company, including the merger with
Motorola, Inc., would result in an event of default, and the lenders under the
Credit Agreement could declare all outstanding borrowings under the Credit
Agreement immediately due and payable. None of the restrictions contained in the
Credit Agreement is expected to have a significant effect on the Company's
ability to operate, and as of September 30, 1999, the Company was in compliance
with all financial and operating covenants under the Credit Agreement. At
September 30, 1999, the Company had available credit of $500 million under the
Credit Agreement. The Company had approximately $106 million of letters of
credit outstanding at September 30, 1999, but has entered into an agreement that
would reduce that amount by $75 million.

7. RESTRUCTURINGS

    In the fourth quarter of 1997, with the change in senior management, the
Company undertook an effort to assess the future viability of its satellite
business. As the satellite business had been in a state of decline, management
of the Company made a decision to streamline the cost structure of its San
Diego-based satellite business by reducing this unit's headcount by 225. In
conjunction with the assessment of the satellite business, the Company also made
a strategic decision with respect to its worldwide consolidated manufacturing
operations that resulted in the closure of its Puerto Rico satellite TV
manufacturing facility, which manufactured receivers used in the private
network, commercial and consumer satellite markets for the reception of analog
and digital television signals, and reduced headcount by 1,100. The Company also
decided to close its corporate office and move from Chicago, Illinois to
Horsham, Pennsylvania, which was completed during the first quarter of 1998.
Costs associated with the closure of facilities ("Facility Costs") include
vacated long-term leases which are payable

through the end of the lease terms which extend through the year 2008. As a
result of the above actions, the Company recorded a pre-tax charge of $36
million during the fourth quarter of 1997.

    As part of the restructuring plan, the Company recorded an additional $16
million of pre-tax charges in the first quarter of 1998 which primarily included
$8 million for severance and other employee separation costs, $3 million of
facility exit costs, including the early termination of a leased facility which
the Company decided to close in the quarter ended March 31, 1998, and $5 million
related to the write-down of fixed assets to their estimated fair values. Of
these charges, $9 million were recorded as cost of sales, $6 million as selling,
general and administrative ("SG&A") expense and $1 million as research and
development ("R&D") expense.

    On April 29, 1999, PRIMESTAR, Inc. ("PRIMESTAR") announced that it had
completed the previously announced sale of its direct broadcast satellite
("DBS") medium-power business and assets to Hughes Electronics Corporation
("Hughes"). Sales to PRIMESTAR accounted for 11% of the Company's sales in 1998.
The Company currently expects future PRIMESTAR purchases of medium-power
equipment from the Company to be insignificant. Further, as a result of the
previously announced purchase by Hughes of PRIMESTAR's rights to acquire certain
high-power satellite assets, the Company does not expect to supply any
high-power equipment to PRIMESTAR. In the first quarter of 1999, in connection
with the announcement of the PRIMESTAR developments, the Company evaluated its
overhead structure and took steps to further consolidate its San Diego,
California and Horsham, Pennsylvania operations, including reducing headcount by
approximately 200. The Company recorded a pre-tax charge of approximately $15
million during the first quarter of 1999 which primarily included $6 million for
severance costs, $6 million for the write-down of PRIMESTAR related inventory to
its lower of cost or market, $2 million for the write-down of fixed assets used
to manufacture PRIMESTAR products to their estimated fair values and $1 million
of facility costs. Of these charges, $8 million were recorded as cost of sales
and $7 million were recorded as SG&A expense.

from January 1, 1998 through September 30, 1999:

(1)  These charges represent a direct reduction to the inventory and property,
     plant and equipment balances to reflect the identified impaired assets at
     their lower of cost or market and fair values, respectively. The amounts
     utilized reflect the disposition of such identified impaired assets.

8. OTHER CHARGES AND LITIGATION COSTS

    The Company incurred certain other pre-tax charges during the first quarter
of 1998 primarily related to management's decision to close a satellite
manufacturing facility due to reduced demand for the products manufactured by
that facility. Concurrent with this decision, the Company determined that the
carrying value of the inventory would not be recoverable and, accordingly, the
Company wrote down the inventory to its lower of cost or market. In addition,
the Company incurred moving costs associated with relocating certain fixed
assets to other facilities, shutdown expenses and legal fees. The above charges
totaled $25 million, of which $18 million are included in cost of sales and $7
million are included in SG&A expense. In addition, the Company incurred $8
million of charges, which are included in "other expense-net," related to costs
incurred by the Partnership, which the Company accounts for under the equity
method. Such costs are primarily related to a $5 million litigation settlement
and compensation expense related to key executives of an acquired company.

     plant and equipment balances to reflect these assets at their lower of cost
     or market and fair values, respectively. The amounts utilized reflect the
     disposition of such identified assets.

    During the three months ended September 30, 1999, the Company recorded a $43
million charge related to the American Arbitration Association panel's interim
decision in the breach of contract dispute between the Company and StarSight
Telecast, Inc. The arbitrators found that the Company had breached a license
agreement and misappropriated certain StarSight trade secrets relating to
electronic program guides and that StarSight is entitled to compensatory and
punitive damages. The amount of such damages will be finally determined by the
arbitrators after further submissions are made by the parties. The Company
estimates that compensatory damages will be in the range of $25 to $36 million.
An additional 50% of such amount will be added as punitive damages, plus
attorneys fees and costs. See Note 5.

9.  OTHER INCOME (EXPENSE) - NET

    Other income (expense)-net for the three and nine months ended September 30,
1999 primarily includes $7 million and $19 million, respectively, related to
gains on the sales of short-term investments offset by $6 million and $17
million, respectively, related to the Company's share of the Partnership losses.
Other income (expense)-net for the three and nine months ended September 30,
1998 primarily reflects $5 million and $23 million, respectively, related to the
Company's share of the Partnership losses, including the Company's share of a $5
million litigation settlement and compensation expense related to key executives
of an acquired company for the nine months ended September 30, 1998, offset by
$7 million and $11 million, respectively, related to gains on the sales of
short-term investments and $5 million for the nine months ended September 30,
1998 related to proceeds received from the settlement of an insurance claim.

10. THE NEXT LEVEL COMMUNICATIONS BUSINESS

    In January 1998, the Company transferred at historical cost the net assets,
the underlying NLC technology, and the management and workforce of NLC to a
newly formed limited partnership (the "Partnership") in exchange for
approximately an 89% limited partnership interest (subject to additional
dilution). Such transaction was accounted for at historical cost. The limited
partnership interest is included in "investments and other assets" in the
accompanying consolidated balance sheet at September 30, 1999. The operating
general partner, which was formed by Spencer Trask & Co. ("Spencer Trask"), an
unrelated third party, acquired approximately an 11% interest in the Partnership
and has the potential to acquire up to an additional 11% in the future. The
Company does not have the option to acquire the operating general partner's
interest in the Partnership. Net assets transferred to the Partnership at
formation of $45 million primarily included property, plant and equipment,
inventories and accounts receivable partially offset by accounts payable and
accrued expenses.

    In addition, in January 1998, the Company advanced $75 million to the
Partnership in exchange for an 8% debt instrument (the "Note"), and the Note
contains normal creditor security rights, including a prohibition against
incurring amounts of indebtedness for borrowed money in excess of $10 million.
Since the repayment of the Note was solely dependent upon the results of the
Partnership's research and development activities and the commercial success of
its product

development, the Company recorded a charge to R&D expense during the quarter
ended March 31, 1998 to fully reserve for the Note concurrent with the funding.
The proceeds of the Note are being utilized to fund the R&D activities of the
Partnership to develop the aforementioned telecommunication technology for
widespread commercial deployment. During 1998, the Company agreed to make
additional equity investments in the Partnership, aggregating $50 million,
beginning in November 1998, to fund the Partnership's growth and assist the
Partnership in meeting its forecasted working capital requirements. The Company
completed these equity investments in the second quarter of 1999.

    The Company accounts for its interest in the Partnership as an investment
under the equity method of accounting. Further, the Company's share of the
Partnership's losses related to future R&D activities, up to a maximum of $75
million, are being offset against the $75 million reserve discussed above. For
the three and nine months ended September 30, 1999, the Company's share of the
Partnership's losses was $6 million and $17 million, respectively, (net of the
Company's share of R&D expenses of $11 million and $32 million, respectively).
For the three and nine months ended September 30, 1998, the Company's share of
the Partnership's losses was $5 million and $23 million, respectively, (net of
the Company's share of R&D expenses of $11 million and $31 million,
respectively). The Company has eliminated its interest income from the Note
against its share of the Partnership's related interest expense on the Note. The
Company's net equity investment in the Partnership was $53 million at September
30, 1999.

    The following summarized financial information is provided for the
Partnership for the three and nine months ended September 30, 1999 and 1998:

    In November, 1999, in connection with the initial public offering of Next
Level Communications, Inc., the corporate successor to the Partnership, the
Company contributed the Note and accrued interest thereon, in exchange for
additional ownership interest in Next Level Communications, Inc. See Note 14.

11. RELATED PARTY TRANSACTIONS

    A wholly-owned subsidiary of AT&T is a greater than 10% stockholder of the
Company. AT&T is also a significant customer of the Company. Sales to AT&T
(Tele-Communications, Inc prior to its merger with AT&T) represented 30% and 31%
of total Company sales for the nine months ended September 30, 1999 and the year
ended December 31, 1998, respectively. Management believes the transactions with
AT&T are at arms length and are under terms no less favorable to the Company
than those with other customers. At September 30, 1999 and December 31, 1998
accounts receivable from AT&T totaled $17 million and $81 million, respectively.

    Earnings (Loss) Per Share. The calculation of diluted weighted-average
shares outstanding included the dilutive effects of stock options and warrants
of 4,271 shares and 12,391 shares, respectively, for the three months ended
September 30, 1999 and the dilutive effects of stock options and warrants of
4,124 shares and 11,409 shares, respectively, for the nine months ended
September 30, 1999. The calculation of diluted weighted-average shares
outstanding included the dilutive effects of stock options and warrants of 2,806
shares and 7,330 shares, respectively, for the three months ended September 30,
1998 and the dilutive effects of stock options and warrants of 2,380 shares and
6,105 shares, respectively, for the nine months ended September 30, 1998.

    License Amortization. Intangible assets consist primarily of a license,
which is being amortized over its 20-year term based on the expected revenue
stream. The revenue earned from the license is solely dependent on the Company's
deployment of digital terminals and such deployment is expected to rise
significantly during the 20-year term. The Company believes the expected revenue
stream is a reliable measure of the future benefit of the license both in the
aggregate and in terms of the periods to which such benefit will be realized.
Accordingly, the Company believes this method of amortization is a more
appropriate method than straight-line. At each reporting date, the Company's
method of amortization requires the determination of a fraction, the numerator
of which is the actual revenues for the period and the denominator of which is
the expected revenues from the license during its 20-year term. Under the
Company's method, amortization for the three and nine months ended September 30,
1999 was approximately $0.8 million and $2.5 million, respectively, and
accumulated amortization as of September 30, 1999 was approximately $3.2
million.

    Comprehensive Income (Loss). Total comprehensive income was $64 million and
$180 million for the three and nine months ended September 30, 1999,
respectively. For the three and nine months ended September 30, 1998, total
comprehensive income was $26 million and total comprehensive loss was $7
million, respectively.

    New Accounting Pronouncements Not Yet Adopted. Statement of Financial
Accounting Standards ("SFAS") No. 133 "Accounting for Derivative Instruments and
Hedging Activities" was issued in June 1998 and, as amended by SFAS No. 137
"Accounting for Derivative Instruments and Hedging Activities -- Deferral of the
Effective Date of SFAS Statement No. 133" in June 1999, is effective for fiscal
years beginning after June 15, 2000. SFAS No. 133 requires that all derivative
instruments be measured at fair value and recognized in the balance sheet as
either assets or liabilities. The Company is currently evaluating the impact
this pronouncement will have on its consolidated financial statements.

14. SUBSEQUENT EVENT

    On November 9, 1999, Next Level Communications, Inc. ("NLCI") priced its
initial public offering of 8,500,000 shares of common stock. NLCI is the
corporate successor to the Partnership, of which a General Instrument subsidiary
was the limited partner. In connection with this offering, the Partnership and
the Company's wholly owned subsidiary, the limited partner, were merged into
NLCI and the Company contributed the Note (see Note 10) and accrued interest
thereon to NLCI in exchange for 64,103,724 shares of common stock of NLCI. This
represents approximately 80% of the shares outstanding immediately after the
offering (approximately 64% on a fully diluted basis) after giving effect to the
exercise of the underwriters' over-allotment option. The Company has deposited
all of its shares into a voting trust that limits its voting power to 49% of all
outstanding shares of common stock; accordingly, the Company will continue to
account for its ownership interest as an investment under the equity method of
accounting. It is anticipated that the voting trust will terminate immediately
upon the completion of the pending merger with Motorola, Inc.

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

NET SALES

    Net sales for the three months ended September 30, 1999 were $544 million,
an increase of $26 million, or 5%, over net sales of $518 million for the three
months ended September 30, 1998. Net sales for the nine months ended September
30, 1999 were $1,590 million compared to $1,424 million for the nine months
ended September 30, 1998, an increase of $166 million, or 12%. The increases in
net sales for the three and nine month periods reflect higher sales of digital
cable systems, transmission and high speed data products, partially offset by
lower sales of analog cable and satellite products. Digital and analog products
represented 60% and 40%, respectively, of total sales for the nine months ended
September 30, 1999 and 54% and 46%, respectively, of total sales for the nine
months ended September 30, 1998.

    Worldwide broadband sales (consisting of digital and analog cable and
wireless television systems, transmission network systems and high speed data
products) of $491 million and $1,397 million for the three and nine months ended
September 30, 1999, respectively, increased $77 million, or 19%, and $293
million, or 27%, respectively, from the comparable 1998 periods, primarily as a
result of increased U.S. sales volume of digital cable terminals and headends,
transmission product sales and high speed data product sales, partially offset
by lower sales of analog cable systems. These sales reflect the commitment of
cable television operators to deploy interactive digital systems in order to
offer advanced entertainment, interactive services and Internet access to their
customers. During the three months ended September 30, 1999 and 1998, broadband
sales in the U.S. were 86% and 88%, respectively, combined U.S. and Canadian
sales were 90% and 89%, respectively, and all other international sales were 10%
and 11%, respectively, of total worldwide broadband sales. For the nine months
ended September 30, 1999 and 1998, broadband sales in the U.S. were 85%,
combined U.S. and Canadian sales were 89% and 86%, respectively, and all other
international sales were 11% and 14%, respectively, of total worldwide broadband
sales. The decrease in international sales from 1998 was experienced primarily
in the Latin American and European regions and international sales are not
expected to return to historical levels in the near-term.

    Worldwide satellite sales of $54 million and $193 million for the three and
nine months ended September 30, 1999, respectively, decreased $51 million, or
49%, and $126 million, or 39%, respectively, from the comparable 1998 period,
primarily as a result of lower sales to PRIMESTAR, Inc. ("PRIMESTAR"). On April
29, 1999, PRIMESTAR announced that it had completed the previously announced
sale of its direct broadcast satellite ("DBS") medium-power business and assets
to Hughes Electronics Corporation ("Hughes"). The Company currently expects
future PRIMESTAR purchases of medium-power equipment from the Company to be
insignificant. Further, as a result of the previously announced purchase by
Hughes of PRIMESTAR's rights to acquire certain high-power satellite assets, the
Company does not expect to supply any high-power equipment to PRIMESTAR.

    During the three months ended September 30, 1999 and 1998, satellite sales
in the U.S. were 40% and 84%, respectively, combined U.S. and Canadian sales
were 90% and 99%, respectively, and all other international sales were 10% and
1%, respectively, of total worldwide satellite sales. For the nine months ended
September 30, 1999 and 1998, satellite sales in the U.S. were 61% and 91%,
respectively, combined U.S. and Canadian sales were 89% and 98%, respectively,
and all other international sales were 11% and 2%, respectively, of total
worldwide satellite sales. The increase in international satellite sales during
1999 was experienced primarily in the Latin American region.

    AT&T (TCI prior to its merger with AT&T) accounted for approximately 30% of
the Company's consolidated net sales for the nine months ended September 30,
1999. For the year ended December 31, 1998, TCI and PRIMESTAR represented
approximately 31% and 11%, respectively, of total Company sales.

GROSS PROFIT

    Gross profit was $158 million and $454 million for the three and nine months
ended September 30, 1999, respectively, compared to $153 million and $387
million for the three and nine months ended September 30, 1998, respectively.
Gross profit was 29% of sales for the three and nine months ended September 30,
1999, respectively, compared to 30% and 27% of sales for the comparable 1998
periods. Gross profit for the nine months ended September 30, 1999 included a $6
million gain, recorded in the second quarter of 1999, related to the favorable
resolution of certain duty matters and $8 million of restructuring charges (see
Note 7 and "Restructurings" below) recorded in the first quarter of 1999,
primarily related to the write-down of PRIMESTAR related inventory to its lower
of cost or market and the write-down of fixed assets used to manufacture
PRIMESTAR products to their estimated fair values. Gross profit for the nine
months ended September 30,


                                       16
<PAGE>   17
1998 included $9 million of restructuring charges (see Note 7 and
"Restructurings" below) and $18 million of other charges (see Note 8 and "Other
Charges" below) recorded in the first quarter of 1998, primarily related to
severance and other employee separation costs, costs associated with the closure
of various facilities, the write-down of fixed assets to their estimated fair
values and the write-down of inventories to their lower of cost or market.

SELLING, GENERAL AND ADMINISTRATIVE

    Selling, general & administrative ("SG&A") expense was $41 million and $132
million for the three and nine months ended September 30, 1999, respectively,
compared to $46 million and $148 million for the three and nine months ended
September 30, 1998, respectively. SG&A expense decreased as a percentage of
sales to 8% for the three and nine months ended September 30, 1999,
respectively, from 9% and 10% for the three and nine months ended September 30,
1998, respectively. SG&A for the nine months ended September 30, 1999 included
$7 million of restructuring charges (see Note 7 and "Restructurings" below)
recorded in the first quarter of 1999, primarily related to severance costs
recorded in connection with the announcement of the PRIMESTAR developments.
These restructuring activities have driven the reductions of ongoing SG&A
expense. SG&A for the nine months ended September 30, 1998 included $6 million
of restructuring charges (see Note 7 and "Restructurings" below) and $7 million
of other charges (see Note 8 and "Other Charges" below) recorded in the first
quarter of 1998, primarily related to severance and other employee separation
costs, costs associated with the closure of various facilities, including moving
costs and costs associated with changing the Company's corporate name.

LITIGATION COSTS

    During the three months ended September 30, 1999, the Company recorded a $43
million charge related to the American Arbitration Association panel's interim
decision in the breach of contract dispute between the Company and StarSight
Telecast, Inc. The arbitrators found that the Company had breached a license
agreement and misappropriated certain StarSight trade secrets relating to
electronic program guides and that StarSight is entitled to compensatory and
punitive damages. The amount of such damages will be finally determined by the
arbitrators after further submissions are made by the parties. The Company
estimates that compensatory damages will be in the range of $25 to $36 million.
An additional 50% of such amount will be added as punitive damages, plus
attorneys fees and costs. In the event this award is ultimately confirmed by a
court, the Company would be able to satisfy the judgment without any material
impact on its financial condition or future operations (see Note 5).

RESEARCH AND DEVELOPMENT

    Research and development ("R&D") expense was $42 million and $125 million
for the three and nine months ended September 30, 1999, respectively, compared
to $42 million and $200 million, respectively, for the comparable 1998 periods.
R&D expense for the nine months ended September 30, 1998 included a $75 million
charge to fully reserve the Partnership Note (see Note 10). Proceeds of the
Partnership Note are being utilized by the Partnership to fund research and
development activities to develop, for widespread commercial deployment, the
next-generation telecommunications technology for the delivery of telephony,
video, and data from the telephone company central office to the home. The
Company's R&D spending in 1999 is focused on new product opportunities,
including advanced digital services, high-speed internet and data systems, and
next generation transmission network systems. In addition, the Company is
incurring R&D expense to develop analog and digital products for international
markets, reduce costs and expand the features of its digital cable and satellite
systems.

OTHER INCOME (EXPENSE)--NET

        For the three and nine months ended September 30, 1999, other
income-net was $1 million and other expense-net was $1 million, respectively.
For the three and nine months ended September 30, 1998 other income-net was $1
million and other expense-net was $9 million, respectively. Other expense
decreased in the nine months ended September 30, 1999 from the comparable 1998
period primarily due to a reduction in the Partnership's losses (see Note 10)
and additional gains on the sales of short-term investments. Other income
(expense)-net for the three and nine months ended September 30, 1999 primarily
includes $7 million and $19 million, respectively, related to gains on the
sales of short-term investments offset by $6 million and $17 million,
respectively, related to the Company's share of the Partnership losses. Other
income (expense)-net for the three and nine months ended September 30, 1998
primarily reflects $5 million and $23 million, respectively, related to the
Company's share of the Partnership losses, including the Company's share of a
$5 million litigation settlement and compensation expense related to key
executives of an acquired company for the nine months ended September 30. 1998,
offset by $7 million and $11 million, respectively, related to gains on the
sales of short-term investments and $5 million for the nine months ended
September 30, 1998 related to proceeds received from the settlement of an
insurance claim.

                                       17
<PAGE>   18
INTEREST INCOME--NET

    Net interest income was $4 million and $12 million for the three and nine
months ended September 30, 1999, respectively, compared to $1 million and $0.1
million for the three and nine months ended September 30, 1998, respectively.
The increases in interest income reflect the higher average cash balances and
debt free position during the three and nine months ended September 30, 1999.

INCOME TAXES

    The Company recorded a provision for income taxes of $11 million and $56
million for the three and nine months ended September 30, 1999, respectively,
and a provision for income taxes of $24 million and $10 million, respectively,
for the comparable 1998 periods. Excluding any restructuring and other charges
and litigation costs recorded during these periods, the effective tax rate was
approximately 37% and 38% for the nine months ended September 30, 1999 and 1998,
respectively.

RESTRUCTURINGS

    In the fourth quarter of 1997, with the change in senior management, the
Company undertook an effort to assess the future viability of its satellite
business. As the satellite business had been in a state of decline, management
of the Company made a decision to streamline the cost structure of its San
Diego-based satellite business by reducing this unit's headcount by 225. In
conjunction with the assessment of the satellite business, the Company also made
a strategic decision with respect to its worldwide consolidated manufacturing
operations that resulted in the closure of its Puerto Rico satellite TV
manufacturing facility, which manufactured receivers used in the private
network, commercial and consumer satellite markets for the reception of analog
and digital television signals, and reduced headcount by 1,100. The Company also
decided to close its corporate office and move from Chicago, Illinois to
Horsham, Pennsylvania, which was completed during the first quarter of 1998.
Costs associated with the closure of facilities include vacated long-term leases
which are payable through the end of the lease terms which extend through the
year 2008. As a result of the above actions, the Company recorded a pre-tax
charge of $36 million during the fourth quarter of 1997 (see Note 7). These
restructuring costs provided cost savings in certain satellite production
processes; however, declining demand for certain satellite products has
substantially offset the cost reductions.

    As part of the restructuring plan, the Company recorded an additional $16
million of pre-tax charges in the first quarter of 1998 which primarily included
$8 million for severance and other employee separation costs, $3 million of
facility exit costs, including the early termination of a leased facility which
the Company decided to close in the quarter ended March 31, 1998, and $5 million
related to the write-down of fixed assets to their estimated fair values (see
Note 7). Of these charges, $9 million were recorded as cost of sales, $6 million
as SG&A expense and $1 million as R&D expense.

    In the first quarter of 1999, in connection with the announcement of the
PRIMESTAR developments, the Company evaluated its overhead structure and has
taken steps to further consolidate its San Diego, California and Horsham,
Pennsylvania operations, including reducing headcount by approximately 200. The
Company recorded a pre-tax charge of approximately $15 million during the first
quarter of 1999 which primarily included $6 million for severance costs, $6
million for the write-down of PRIMESTAR related inventory to its lower of cost
or market, $2 million for the write-down of fixed assets used to manufacture
PRIMESTAR products to their estimated fair values and $1 million of facility
costs (see Note 7). Of these charges, $8 million were recorded as cost of sales
and $7 million were recorded as SG&A expense.

OTHER CHARGES

    The Company incurred certain other pre-tax charges during the first quarter
of 1998 primarily related to management's decision to close a satellite
manufacturing facility due to reduced demand for the products manufactured by
that facility. Concurrent with this decision, the Company determined that the
carrying value of the inventory would not be recoverable and, accordingly, the
Company wrote down the inventory to its lower of cost or market. In addition,
the Company incurred moving costs associated with relocating certain fixed
assets to other facilities, shutdown expenses and legal fees. The above charges
totaled $25 million, of which $18 million are included in cost of sales and $7
million are included in SG&A expense. In addition, the Company incurred $8
million of charges, which are included in "other expense-net," related to costs
incurred by the Partnership, which the Company accounts for under the equity
method. Such costs are primarily related to a $5 million litigation settlement
and compensation expense related to key executives of an acquired company (see
Note 8).

                                       18

LIQUIDITY AND CAPITAL RESOURCES

    For the nine months ended September 30, 1999 and 1998, cash provided by
operations was $305 million and $145 million, respectively. Cash provided by
operations primarily reflects net income excluding non-cash charges and improved
working capital levels in both periods.

    At September 30, 1999, working capital (current assets less current
liabilities) was $774 million compared to $437 million at December 31, 1998. The
Company believes that working capital levels are appropriate to support the
growth of the business; however, there can be no assurance that future
industry-specific developments or general economic trends will not alter the
Company's working capital requirements. As part of its overall treasury program,
the Company will, from time to time, sell certain receivable balances to
financial institutions to manage credit risk and/or working capital levels.

    During the nine months ended September 30, 1999 and 1998, the Company
invested $45 million and $59 million, respectively, in equipment and facilities.
The Company expects to continue to expand its capacity to meet increased current
and anticipated future demands for digital products, with capital expenditures
for the year expected to approximate $65 million. The Company's R&D expenditures
were $125 million and $200 million (including the $75 million funding related to
the Partnership's R&D activities) during the nine months ended September 30,
1999 and 1998, respectively. The Company expects total R&D expenditures to
approximate $170 million for the year ending December 31, 1999.

    The Company has a bank credit agreement (the "Credit Agreement") which
provides a $600 million unsecured revolving credit facility and matures on
December 31, 2002. The Credit Agreement permits the Company to choose between
two competitive interest rate options. The Credit Agreement contains financial
and operating covenants, including limitations on guarantee obligations, liens
and the sale of assets, and requires the maintenance of certain financial
ratios. Significant financial ratios include (i) maintenance of consolidated net
worth above $600 million adjusted for 50% of cumulative positive quarterly net
income subsequent to June 30, 1997; (ii) maintenance of an interest coverage
ratio based on EBITDA in comparison to net interest expense of greater than 5 to
1; and (iii) maintenance of a leverage ratio comparing total indebtedness to
EBITDA of less than 3 to 1. None of the restrictions contained in the Credit
Agreement is expected to have a significant effect on the Company's ability to
operate. Under the Credit Agreement, certain changes in the control of the
Company, including the merger with Motorola, Inc., would result in an event of
default, and the lenders under the Credit Agreement could declare all
outstanding borrowings under the Credit Agreement immediately due and payable.
If the Company is unsuccessful in getting the lenders under the Credit Agreement
to waive the event of default upon the completion of the proposed merger with
Motorola, Inc., the Company believes that is has sufficient potential
alternatives, including cash and cash equivalents, working capital and/or credit
facilities provided through Motorola, Inc., to meet its future cash
requirements. As of September 30, 1999, the Company was in compliance with all
financial and operating covenants contained in the Credit Agreement and had
available credit of $500 million.

    The Company's management assesses its liquidity in terms of its overall
ability to obtain cash to support its ongoing business levels and to fund its
growth objectives. The Company's principal sources of liquidity both on a
short-term and long-term basis are cash flows provided by operations together
with other financing arrangements. The Company believes that based upon its
analysis of its consolidated financial position and its expected operating cash
flows from future operations, along with available funding under the Credit
Agreement or other financing alternatives subsequent to the proposed merger with
Motorola, Inc., cash flows will be adequate to fund operations, research and
development and capital expenditures. There can be no assurance, however, that
future industry-specific developments or general economic trends will not
adversely affect the Company's operations or its ability to meet its cash
requirements.

NEW TECHNOLOGIES

    The Company operates in a dynamic and competitive environment, in which its
success will be dependent upon numerous factors, including its ability to
continue to develop appropriate technologies and successfully implement
applications based on those technologies. In this regard, the Company has made
significant investments to develop advanced systems and equipment for the cable
and satellite television, Internet/data delivery and local telephone access
markets. Additionally, the future success of the Company will be dependent on
the ability of the cable and satellite television operators to successfully
market the services provided by the Company's advanced digital terminals to
their customers. Furthermore, as a result of the higher costs of initial
production, digital products presently being shipped carry lower margins than
the Company's mature analog products.

    Management of the Company expects cable television operators in the United
States and abroad to continue to purchase analog products to upgrade their basic
networks and to develop, using U.S. architecture and systems, international
markets


                                       19
<PAGE>   20
where cable penetration is low and demand for entertainment programming is
growing. However, management expects that demand in North America for its analog
cable products will continue to decline.

    As the Company continues to introduce new products and technologies and such
technologies gain market acceptance, there can be no assurance that sales of
products based on new technologies will not affect the Company's product sales
mix and/or will not have an adverse impact on sales of certain of the Company's
other products. For example, sales of analog cable products have been impacted
by a shift to digital deployment in North America.

INTERNATIONAL MARKETS

    Management of the Company believes that additional growth for the Company
will come from international markets, although the Company's international sales
decreased during 1998 and have remained at these levels during 1999. There can
be no assurance that international sales will increase to historical levels in
the near future.

EFFECT OF INFLATION

    The Company continually attempts to minimize any effect of inflation on
earnings by controlling its operating costs and selling prices. During the past
few years, the rate of inflation has been low and has not had a material impact
on the Company's results of operations.

READINESS FOR YEAR 2000

    The Company is preparing for the impact of the arrival of the Year 2000 on
its business, as well as on the businesses of its customers, suppliers and
business partners. The "Year 2000 Issue" is a term used to describe the problems
created by systems that are unable to accurately interpret dates after December
31, 1999. These problems are derived predominantly from the fact that many
software programs have historically categorized the "year" in a two-digit
format. The Year 2000 Issue creates potential risks for the Company, including
potential problems in the Company's products as well as in the Information
Technology ("IT") and non-IT systems that the Company uses in its business
operations. The Company may also be exposed to risks from third parties with
whom the Company interacts who fail to adequately address their own Year 2000
Issues.

The Company's State of Readiness

    While the Company's Year 2000 efforts have been underway for several years,
the Company centralized its focus on addressing the Year 2000 Issue in 1998 by
forming a Year 2000 cross-functional project team of senior managers, chaired by
the Company's Vice President of Information Technology who reports directly to
the Company's Chief Executive Officer on this issue. The Audit Committee of the
Board of Directors is advised periodically on the status of the Company's Year
2000 compliance program.

    The Year 2000 project team has developed a phased approach to identifying
and remediating Year 2000 Issues, with many of these phases overlapping with one
another or conducted simultaneously.

    The first phase was to develop a corporate-wide, uniform strategy for
addressing the Year 2000 Issue and to assess the Company's current state of Year
2000 readiness. This included a review of all IT and non-IT systems, including
Company products and internal operating systems for potential Year 2000 Issues.
The Company completed this phase prior to the end of 1998. In addition, during
this phase the Company developed its Year 2000 Policy Statement which was
released to the Company's customers, suppliers and business partners.

    The second phase of the Company's Year 2000 compliance program (begun
simultaneously with the first phase) was to define a Year 2000 "Compliance"
standard and to develop uniform test plans and test methodologies, building on
work already done by one of the Company's engineering groups. The Company
developed a comprehensive Year 2000 test plan and test methodologies for the
testing of its products, as well as third-party products. The Company has
adopted the following six compliance categories for its products: "Compliant,"
"Compliant with Upgrade," "Compliant with Minor Issues," "Not Compliant or End
of Life Product," "Testing yet to be Completed" and "Testing not Required." The
creation of these six categories has assisted the Company in communicating with
its customers, suppliers and business partners regarding the Year 2000 status of
the Company's products.

                                       20
<PAGE>   21
    To aid in communication with the Company's customers, suppliers and business
partners, the Company developed an Internet web site that identifies the current
Year 2000 status for each of the Company's products in accordance with the
Company's Year 2000 compliance standard. The web site, which is updated
periodically, also identifies available upgrades, as well as the contemplated
completion date of testing and remediation for such products. In addition, the
Company has provided detailed, customer-specific inventory information to major
customers on a product-by-product basis in order to further assist such
customers with their own Year 2000 compliance programs. In furtherance of
providing information about its Year 2000 testing and remediation program, the
Company has disclosed its test plan and methodologies to certain of its
customers, strategic vendors and business partners. The Company is also
participating in industry-wide joint system testing efforts and has participated
in industry-wide forums with the Federal Communications Commission in order to
facilitate awareness in the industry of Year 2000 Issues.

     The Company has also undertaken a review of its internal IT and non-IT
systems to identify potential Year 2000 Issues. In 1996, the Company began the
process of implementing a uniform worldwide business and accounting information
system to improve internal reporting processes. The internal IT systems replaced
include order entry systems, procurement and inventory management systems, and
the Company's general financial systems. Based upon representations from the
manufacturer and the Company's own internal testing, the Company believes that
this uniform information system is Year 2000 compliant. The Company also has
identified, replaced and/or upgraded legacy business systems that were not Year
2000 compliant and were not part of the uniform worldwide business and
accounting information system. In conjunction with the Company's review of
internal IT systems, the Company engaged an outside consulting firm with Year
2000 consulting experience to perform an assessment of the Company's processes
and test methodologies and to benchmark such plans and methodologies against the
practices of other companies. Based on these benchmark comparisons, certain
recommendations were made related to the test plans. The Company is currently
addressing these recommendations. With respect to non-IT systems, the Company is
actively analyzing its in-line manufacturing equipment in order to assess and
remediate any Year 2000 issues. To date, no material problems have been
discovered, and the Company will continue to review, test and remediate (if
necessary) such equipment. The Company has also evaluated its other critical
non-IT facility and internal systems with date sensitive operating controls for
Year 2000 Issues. While the Company believes that most of these systems will
function without substantial Year 2000 compliance problems, the Company will
continue to review, test and remediate (if necessary) such systems.

    The third phase of the Company's Year 2000 compliance program is the actual
testing and remediation (if necessary) of the Company's IT products and systems.
The Company has prioritized its testing and remediation work, focusing on
products which the Company believes are more likely to be impacted by Year 2000
Issues. The Company has completed the testing and remediation (as necessary) of
substantially all of its products in accordance with its adopted test plans and
methodologies (except for end of life products). As of September 30, 1999, the
Company estimates that it has completed approximately 98% of the Year 2000
readiness analysis required for its Advanced Network Systems, Digital Network
Systems and Transmission Network Systems products. As of September 30, 1999, the
Company estimates that it has completed approximately 95% of the Year 2000
readiness analysis for its Satellite and Broadcast Network Systems products. For
certain of the Company's remaining products, testing and remediation (if
necessary) is currently anticipated to be completed during the fourth quarter of
1999. The Company has completed testing and remediation of substantially all of
its IT and non IT internal systems.

    The Company is presently evaluating each of its principal suppliers, service
providers and other business partners to determine each of such party's Year
2000 status. The Company has developed a questionnaire and a Year 2000
certification for use with such third parties, and, as of September 30, 1999,
the Company had contacted approximately 300 vendors about their Year 2000
compliance, including many of the vendors that the Company has identified as
critical vendors. The Company is currently focused on obtaining Year 2000
Certifications or assurances from approximately 50 of these suppliers. The
Company is currently developing appropriate contingency plans regarding these
critical vendors, where formal Year 2000 certification has not been attained.
The Company anticipates that this evaluation, along with the development and
implementation of vendor contingency plans, will be on-going through the
remainder of 1999. To date, no significant problems have been discovered.

    The Company is working jointly with customers, strategic vendors and
business partners to identify and resolve any Year 2000 issues that may impact
the Company. However, there can be no assurance that the companies with which
the Company does business will achieve a Year 2000 conversion in a timely
fashion, or that such failure to convert by another company will not have a
material adverse effect on the Company.

The Costs to Address the Company's Year 2000 Issues

    The total cost associated with the Company's Year 2000 remediation is not
expected to be material to the Company's financial condition or results of
operations. The estimated total cost of the Company's Year 2000 remediation is
not expected to exceed $5 million. Through September 30, 1999, the Company has
spent approximately $3 million in connection with Year 2000 Issues. The cost of
implementing the uniform worldwide business and accounting information system
has not been included in this figure since the replacement of the previous
systems was not accelerated due to Year 2000 Issues. All Year 2000 expenditures
are made from the respective departments' budgets. The percentage of the IT
budget during 1998 used for Year 2000 remediation was less than 3% and is
expected to represent less than 3% of the IT budget for 1999. No IT projects
have been deferred due to Year 2000 efforts.

The Risks of the Company's Year 2000 Issues

    There can be no assurance that the Company will be completely successful in
its efforts to address Year 2000 Issues. If some of the Company's products are
not Year 2000 compliant, the Company could suffer lost sales or other negative
consequences, including, but not limited to, diversion of resources, damage to
the Company's reputation, increased service and warranty costs and litigation,
any of which could materially adversely affect the Company's business operations
or financial statements.

    The Company is also dependent on third parties such as its customers,
suppliers, service providers and other business partners. If these or other
third parties fail to adequately address Year 2000 Issues, the Company could
experience a negative impact on its business operations or financial statements.
For example, the failure of certain of the Company's principal suppliers to have
Year 2000 compliant internal systems could impact the Company's ability to
manufacture and/or ship its products or to maintain adequate inventory levels
for production.

The Company's Contingency Plans

    The Company is evaluating the need for certain contingency plans to address
situations that may result if the Company or any of the third parties upon which
the Company is dependent is unable to achieve Year 2000 readiness. For example,
the Company has developed plans and procedures for its customer service division
to assist customers with the transition through the Year 2000. Part of this plan
includes processes and procedures recently used by the Company in connection
with a program to upgrade a substantial number of analog addressable controllers
to solve a date rollover issue prior to the year 1999. The Company is also
evaluating the need for increasing inventory levels of key components of its
manufactured products. Since the Company's Year 2000 compliance program is
ongoing, its ultimate scope, as well as the consideration of additional
contingency plans, will continue to be evaluated as new information becomes
available.

Year 2000 Forward-Looking Statements

    The foregoing Year 2000 discussion contains "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995. Such
statements, including without limitation, anticipated costs and the dates by
which the Company expects to complete certain actions, are based on management's
best current estimates, which were derived utilizing numerous assumptions about
future events, including the continued availability of certain resources,
representations received from third parties and other factors. However, there
can be no guarantee that these estimates will be achieved, and actual results
could differ materially from those anticipated. Specific factors that might
cause such material differences include, but are not limited to, the ability to
identify and remediate all relevant IT and non-IT systems, results of Year 2000
testing, adequate resolution of Year 2000 Issues by businesses and other third
parties who are service providers, suppliers or customers of the Company,
unanticipated system costs, the adequacy of and ability to develop and implement
contingency plans and similar uncertainties. The "forward-looking statements"
made in the foregoing Year 2000 discussion speak only as of the date on which
such statements are made, and the Company undertakes no obligation to update any
forward-looking statement to reflect events or circumstances after the date on
which such statement is made or to reflect the occurrence of unanticipated
events.

FORWARD-LOOKING INFORMATION

    The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. This Management's Discussion and
Analysis of Financial Condition and Results of Operations and other sections of
this Form 10-Q may include forward-looking statements concerning, among other
things, the Company's prospects, developments and business strategies. These
forward-looking statements are identified by their use of such terms and phrases
as "intends,"

"expected," "project," "projects," "projected," "projections," "plans,"
"anticipates," "anticipated," "should," "designed to," "foreseeable future,"
"believe," "believes," "subject to" and "scheduled." These forward-looking
statements are subject to certain uncertainties and other factors that could
cause actual results to differ materially from such statements. These risks
include, but are not limited to, factors relating to the proposed merger with
Motorola, Inc., uncertainties relating to general political and economic
conditions, uncertainties relating to government and regulatory policies,
uncertainties relating to customer plans and commitments, the Company's
dependence on the cable television industry and cable television capital
spending, Year 2000 readiness, the pricing and availability of equipment,
materials and inventories, technological developments, the competitive
environment in which the Company operates, changes in the financial markets
relating to the Company's capital structure and cost of capital, the
uncertainties inherent in international operations and foreign currency
fluctuations and authoritative generally accepted accounting principles or
policy changes from such standard-setting bodies as the Financial Accounting
Standards Board and the Securities and Exchange Commission. Reference is made to
Exhibit 99 in this Form 10-Q for a further discussion of such factors. Readers
are cautioned not to place undue reliance on these forward-looking statements,
which speak only as of the date the statement was made. The Company undertakes
no obligation to publicly update or revise any forward-looking statements,
whether as a result of new information, future events or otherwise.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    A significant portion of the Company's products are manufactured or
assembled in Taiwan and Mexico. These foreign operations are subject to market
risk changes with respect to currency exchange rate fluctuations, which could
impact the Company's consolidated financial statements. The Company monitors its
underlying exchange rate exposures on an ongoing basis and continues to
implement selective hedging strategies to reduce the market risks from changes
in exchange rates. On a selective basis, the Company enters into contracts to
limit the currency exposure of monetary assets and liabilities, contractual and
other firm commitments denominated in foreign currencies and the currency
exposure of anticipated, but not yet committed, transactions expected to be
denominated in foreign currencies. The use of these derivative financial
instruments allows the Company to reduce its overall exposure to exchange rate
movements since the gains and losses on these contracts substantially offset
losses and gains on the assets, liabilities and transactions being hedged.

    Foreign currency exchange contracts are sensitive to changes in exchange
rates. As of September 30, 1999, a hypothetical 10% fluctuation in the exchange
rate of foreign currencies applicable to the Company, principally the new Taiwan
dollar, would result in a net $3 million gain or loss on the contracts the
Company has outstanding, which would offset the related net loss or gain on the
assets, liabilities and transactions being hedged.

                                     PART II

                                OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

    A securities class action is presently pending in the United States District
Court for the Northern District of Illinois, Eastern Division, In Re General
Instrument Corporation Securities Litigation. This action, which consolidates
numerous class action complaints filed in various courts between October 10 and
October 27, 1995, is brought by plaintiffs, on their own behalf and as
representatives of a class of purchasers of the Distributing Company's common
stock during the period March 21, 1995 through October 18, 1995. The complaint
alleges that the Distributing Company and certain of its officers and directors,
as well as Forstmann Little & Co. and certain related entities, violated the
federal securities laws, namely, Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), prior to the
Distribution, by allegedly making false and misleading statements and failing to
disclose material facts about the Distributing Company's planned shipments in
1995 of its CFT2200 and Digicipher(R) products. Also pending in the same court,
under the same name, is a derivative action brought on behalf of the
Distributing Company. The derivative action alleges that, prior to the
Distribution, the members of the Distributing Company's Board of Directors,
several of its officers and Forstmann Little & Co. and related entities have
breached their fiduciary duties by reason of the matter complained of in the
class action and certain defendants' alleged use of material non-public
information to sell shares of the Distributing Company's stock for personal
gain. Both actions seek unspecified damages and attorneys' fees and costs. The
court granted the defendants' motion to dismiss the original complaints in both
of these actions, but allowed the plaintiffs in each action an opportunity to
file amended complaints. Amended complaints were filed on November 7, 1997. The
defendants answered the amended consolidated complaint in the class actions,
denying liability, and filed a renewed motion to dismiss the derivative action.
On September 22, 1998, defendants' motion to dismiss the derivative action was
denied. In November 1998, the defendants filed an answer to the derivative
action, denying liability. On January 21, 1999, the plaintiffs in the class
actions filed their motion for class certification, including the defendants'
opposition. No ruling has been made on the class certification issue. The
Company intends to vigorously contest these actions.

    An action entitled BKP Partners, L.P. v. General Instrument Corp. was
brought in February 1996 by certain holders of preferred stock of Next Level
Communications ("NLC"), which merged into a subsidiary of the Distributing
Company in September 1995. The action was originally filed in the Northern
District of California and was subsequently transferred to the Northern District
of Illinois. The plaintiffs allege that the defendants violated federal
securities laws by making misrepresentations and omissions and breached
fiduciary duties to NLC in connection with the acquisition of NLC by the
Distributing Company. Plaintiffs seek, among other things, unspecified
compensatory and punitive damages and attorneys' fees and costs. On September
23, 1997, the district court dismissed the complaint, without prejudice, and the
plaintiffs were given until November 7, 1997 to amend their complaint. On
November 7, 1997, plaintiffs served the defendants with an amended complaint,
which contains allegations substantially similar to those in the original
complaint. The defendants filed a motion to dismiss parts of the amended
complaint and answered the balance of the amended complaint, denying liability.
On September 22, 1998, the district court dismissed with prejudice the portion
of the complaint alleging violations of Section 14(a) of the Exchange Act, and
denied the remainder of the defendants' motion to dismiss. In November, 1998,
the defendants filed an answer to the remaining parts of the amended complaint,
denying liability. The Company intends to vigorously contest this action.

    In connection with the Distribution, the Company has agreed to indemnify
General Semiconductor with respect to its obligations, if any, arising out of or
in connection with the matters discussed in the preceding two paragraphs.

    On February 19, 1998, a consolidated securities class action complaint
entitled In Re Nextlevel Systems, Inc. Securities Litigation was filed in the
United States District Court for the Northern District of Illinois, Eastern
Division, naming the Company and certain former officers and directors as
defendants. The complaint was filed on behalf of stockholders who purchased or
otherwise acquired stock of the Company between July 25, 1997 and October 15,
1997. The complaint alleged that the defendants violated Sections 11 and 15 of
the Securities Act of 1933, as amended (the "Securities Act"), and Sections
10(b) and 20(a) of the Exchange Act and Rule 10b-5 thereunder by making false
and misleading statements about the Company's business, finances and future
prospects. The complaint seeks damages in an unspecified amount. On April 9,
1998, the plaintiffs voluntarily dismissed their Securities Act claims. On May
5, 1998, the defendants moved to dismiss the remaining counts of the complaint.
That motion was denied on March 31, 1999 and defendants' answer was filed on
June 25, 1999. On July 30, 1999, defendants filed a motion seeking
reconsideration of the denial of their motion to dismiss. The Company intends to
vigorously contest this action.

    On March 5, 1998, an action entitled DSC Communications Corporation and DSC
Technologies Corporation v. Next Level Communications L.P., KK Manager, L.L.C.,
General Instrument Corporation and Spencer Trask & Co., Inc. was filed in the
Superior Court of the State of Delaware in and for New Castle County (the
"Delaware Action"). In that action, DSC Communications Corporation and DSC
Technologies Corporation (collectively, "DSC") alleged that in connection with
the formation of the Partnership and the transfer to it of NLC's switched
digital video technology, the Partnership and KK Manager, L.L.C. misappropriated
DSC's trade secrets; that the Company improperly disclosed trade secrets when it
conveyed such technology to the Partnership; and that Spencer Trask & Co., Inc.
conspired to misappropriate DSC's trade secrets. The plaintiffs sought actual
damages for the defendants' purported unjust enrichment, disgorgement of
consideration, exemplary damages and attorney's fees, all in unspecified
amounts. In April 1998, the Company and the other defendants filed an action in
the United States District Court for the Eastern District of Texas, requesting
that the federal court preliminarily and permanently enjoin DSC from prosecuting
the Delaware Action because by pursuing such action, DSC effectively was trying
to circumvent and relitigate the Texas federal court's November 1997 judgment in
a previous lawsuit involving DSC, pursuant to which NLC had paid over $140
million. On May 14, 1998, the Texas court granted a preliminary injunction
preventing DSC from proceeding with the Delaware Action. That injunction order
was appealed to the United States Court of Appeals for the Fifth Circuit. On
June 21, 1999, the Fifth Circuit affirmed the Texas federal court's grant of the
preliminary injunction. On July 15, 1999, the Texas federal court granted the
Delaware defendants' motion for summary judgment and issued its final judgment
permanently enjoining DSC from prosecuting and continuing the Delaware Action.

    In May 1997, StarSight Telecast, Inc. ("StarSight") filed a Demand for
Arbitration against the Company alleging that the Company breached the terms of
a license agreement with StarSight by (a) developing a competing product that
wrongfully incorporates StarSight's technology and inventions claimed within a
certain StarSight patent, (b) failing to promote and market the StarSight
product as required by the license agreement, and (c) wrongfully using
StarSight's technical information, confidential information and StarSight's
graphical user interface in breach of the license agreement. StarSight sought
injunctive relief as well as damages. The first part of a bifurcated arbitration
proceeding, relating to the Company's advanced analog products, began on March
22, 1999 before an arbitration panel of the American Arbitration Association in
San Francisco, California. Oral arguments to the panel by the Company and
StarSight were concluded on May 23, 1999. On October 4, 1999, the arbitration
panel released an interim decision with respect to advanced analog products
only. The arbitration panel found that the Company had breached the license
agreement and had misappropriated certain StarSight trade secrets relating to
electronic program guides. The arbitration panel rejected StarSight's
interpretation of its patents and also found that the Company did not
commercialize products that incorporate those patents. The panel further denied
StarSight's request for an injunction. The arbitration panel found that
StarSight is entitled to compensatory and punitive damages. The amount of such
damages will be finally determined by the arbitrators based on damage
calculations submitted by the parties. The Company estimates that compensatory
damages will be in the range of $25 to $36 million. An additional 50% of such
amount will be added as punitive damages, plus attorneys fees and costs. General
Instrument has not determined whether it will oppose confirmation of the damage
award. A separate phase of the arbitration relating to the use of electronic
program guides on digital cable set-top terminals and satellite receivers is not
anticipated to be scheduled until the second quarter of 2000. Unlike its
advanced analog products, the Company does not sell a Company electronic program
guide with its digital cable set-top terminals. The Company denies StarSight's
allegations in the second phase and will continue to vigorously contest this
action.

    On November 30, 1998, an action entitled Gemstar Development Corporation and
Index Systems, Inc. v. General Instrument Corporation was filed in the United
States District Court for the Northern District of California. The complaint
alleges infringement by the Company of two U.S. patents allegedly covering
electronic program guides. The complaint seeks unspecified damages and an
injunction. After filing this action, the plaintiffs sought to consolidate
discovery for this action with other program guide related patent infringement
actions pending against Pioneer Electronics Corp., Scientific-Atlanta, Inc., and
Prevue Networks, Inc. On April 26, 1999, the Judicial Panel on Multidistrict
Litigation ordered the transfer of this action to the Northern District of
Georgia for consolidated pretrial proceedings with the Pioneer Electronics Corp.
and Scientific-Atlanta, Inc. actions. Scheduling and other preliminary discovery
matters are currently awaiting an order from the Court. The Company denies that
it infringes the subject patents and intends to vigorously defend this action.

 ITEM 5.  OTHER INFORMATION

    On November 9, 1999, Next Level Communications, Inc. priced its initial
public offering of 8,500,000 shares of common stock. Next Level Communications,
Inc. is the corporate successor to Next Level Communications L.P., of which a
General Instrument subsidiary was the limited partner. In connection with this
offering, Next Level Communications L.P. and the limited partner were merged
into Next Level Communications, Inc. and General Instrument received 64,103,724
shares of common stock of Next Level Communications, Inc. This represents
approximately 80% of the shares outstanding immediately after the offering
(approximately 64% on a fully diluted basis) after giving effect to the exercise
of the underwriters' over-allotment option.
