                               PROSPECTUS SUMMARY
 
    The following summary information is qualified in its entirety by the
detailed information and consolidated financial statements and notes thereto
appearing elsewhere in this Prospectus or incorporated by reference herein. On
July 25, 1997, the Company was spun off (the "Distribution") from its former
parent company, General Instrument Corporation (the "Distributing Company"),
under the name "NextLevel Systems, Inc.", through a distribution of the
Company's common stock, par value $.01 per share (the "Common Stock"), to the
stockholders of the Distributing Company. Immediately following the
Distribution, the Distributing Company changed its corporate name to "General
Semiconductor, Inc." ("General Semiconductor"). Effective February 2, 1998, the
Company changed its corporate name from "NextLevel Systems, Inc." to "General
Instrument Corporation". Unless the context otherwise requires, references to
the "Company" or "General Instrument" include General Instrument Corporation and
its direct or indirect subsidiaries and the business of the Company as conducted
by the Distributing Company prior to the Distribution.
 
                                  THE COMPANY
 
OVERVIEW
 
    The Company 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 leading 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"), the
Company provides next-generation broadband telephony network solutions with the
Partnership's NLevel(3)-Registered Trademark- Switched Digital Access System
("NLevel(3)").
 
BUSINESS STRATEGY
 
    The Company's strategy is to use its technological leadership in providing
secure broadband systems and equipment to enhance its leading position in its
traditional markets while expanding into new markets. This strategy is based on
the belief that (i) consumers in the United States and international markets
will continue to demonstrate an increasing demand for new information and
entertainment services and (ii) content and service providers will continue to
create new bandwidth-intensive video, voice and data applications. The Company's
management believes that these factors will generate a continuing need for
systems and equipment with greater capacity for all networks and architectures.
 
DEMAND FOR SYSTEMS AND EQUIPMENT SUPPORTING NEW BANDWIDTH INTENSIVE APPLICATIONS
 
    The Company expects the market for systems and equipment supporting new
bandwidth intensive applications to grow significantly as a result of the
availability of new information and entertainment services for consumers.
 
    - CABLE SYSTEM UPGRADES.  Cable operators are upgrading their systems to
provide for two-way capabilities and additional capacity in order to provide
advanced services such as Internet access, video-on-demand ("VOD") and
telephony. The cable infrastructure, with its high capacity access into the
home, is regarded as an attractive network for the delivery of advanced
communication and entertainment services. The Company believes that the
commercialization of advanced broadband systems and equipment, which provide for
greatly expanded channel capacity and programming options, improved quality and

features and
 
                                       5

services, presents a significant opportunity for the Company. Recent
developments in the cable and telecommunications industries, including the
announcement of a proposed merger between AT&T Corporation ("AT&T") and
Tele-Communications, Inc. ("TCI"), Microsoft Corporation's ("Microsoft") $1
billion investment in Comcast Cable Communications, Inc. ("Comcast"), and the
purchase of Marcus Cable and Charter Communications, Inc. ("Charter") by Paul
Allen, a founder of Microsoft, are expected to accelerate cable system operator
spending for these advanced broadband systems to facilitate the offering of
advanced services.
 
    - TELEPHONY DEVELOPMENTS.  At the same time cable operators are upgrading
their systems to offer advanced services, Regional Bell Operating Companies and
other telecommunications companies are also seeking a cost-effective way to
deliver standard telephony and advanced services to the home, including
high-speed data/Internet, distance learning and video services. The Company
believes that this presents a significant opportunity for suppliers, such as the
Partnership, which provide integrated broadband access systems that enable these
services from a single access platform.
 
THE COMPANY'S MARKET LEADERSHIP
 
    The Company has a leading position in providing systems and equipment to the
broadband communications market. Currently, the Company is a leading supplier to
16 of the 20 largest cable television multiple systems operators ("MSOs") in the
United States and believes that it has supplied a majority of the addressable
systems in use by cable television operators in the United States and abroad.
 
    - LEADER OF COMMERCIALIZATION OF DIGITAL BROADBAND SYSTEMS.  The Company is
the leading supplier of interactive digital cable television systems. Through
June 30, 1998, the Company had shipped approximately 600 digital cable
television head-end systems, passing approximately 28 million homes, and over
1.4 million two-way interactive digital cable television set-top terminals to
broadband system operators. The Company has entered into definitive agreements,
with an estimated value of $4.5 billion, to supply approximately 15 million
digital set-top terminals to leading North American cable operators, with a
collective subscriber base of over 46 million, over the next three to five
years.
 
    During the second half of 1998 and during 1999, the Company expects to
introduce new two-way interactive set-top terminal models, including terminals
targeted at European and other international cable operators and a high-end
terminal that incorporates a built-in Data-Over-Cable-Service/Interoperability
Specification ("DOCSIS")-compliant cable modem, Internet protocols ("IP") and a
unique triple tuner architecture that will ultimately enable consumers to watch
television, surf the World Wide Web and talk on the telephone simultaneously.
 
    - THE WORLD LEADER IN ANALOG ADDRESSABILITY.  The Company is the world's
leading provider of addressable analog set-top systems. The Company's latest
two-way interactive advanced analog terminal provides cable operators with
Internet access, interactive programming guides, CD-quality music, near
video-on-demand ("NVOD"), supplemental sports and entertainment information and
local information-on-demand.
 
    - NEXT GENERATION TELEPHONY.  The Partnership, in which the Company has an
89% limited partnership interest, is a leading provider of the next generation
of integrated full service digital loop carrier ("DLC") and fiber-to-the-curb
("FTTC") systems for the delivery of telephony, video and data for local
telephone companies. The Partnership's product, NLevel(3), is designed to permit
the cost effective delivery of a suite of standard telephony and advanced
services, including high-speed data/Internet, distance learning, VOD and video
telephony, to the home from a single access platform. In July 1998, the
Partnership was selected to supply DLC and FTTC systems to U S West
Communications ("U S West") for the delivery of broadband video, high-speed
data/Internet, and basic telephone services. The Company has also contracted to
supply U S West with 450,000 broadband xDSL access lines and to
 
                                       6
<PAGE>
supply Bell Atlantic Corporation ("Bell Atlantic") with 1,000,000 lines of
telephone service. The Partnership is currently deploying its NLevel(3) products
pursuant to these contracts.
 
STRATEGIC PARTNER AND CUSTOMER RELATIONSHIPS
 
    The Company recently entered into several strategic relationships, including
equity investments in the Company by large MSOs, which are expected to provide a
strong foundation for future business development and to reinforce the Company's
position as a leading provider of the next generation of broadband
communications equipment and systems.
 
    - CABLE CUSTOMER EQUITY OWNERSHIP.  The Company has issued warrants to
purchase approximately 29 million shares of Common Stock to leading North
American cable system operators. These warrants were issued in connection with
the definitive agreements to supply approximately 15 million digital set-top
terminals to such operators. Included among the cable operators entitled to
exercise the warrants upon the purchase of set-top terminals from the Company
are TCI, Time Warner Cable ("Time Warner"), MediaOne of Delaware, Inc.
("MediaOne"), Comcast, Cox Communications, Inc. ("Cox"), Adelphia Communication
Corporation ("Adelphia"), Shaw Communications, Inc. ("Shaw"), Jones Intercable,
Inc. ("Jones") and Charter.
 
    - SET-TOP AUTHORIZATION SERVICES.  The Company issued 21,356,000 shares of
its Common Stock to an affiliate of TCI in connection with the Company's
acquisition of the set-top authorization services business that controls the
receipt of cable programming services delivered to subscribers by TCI's Headend
In The Sky-Registered Trademark-. The Company now provides national
authorization services throughout the United States to TCI, its affiliates and
other operators, many with relatively small individual systems that could not
otherwise justify the initial capital investment required to launch a local
digital headend computer control system.
 
    - SONY CORPORATION.  The Company has announced plans to enter into a
strategic alliance with Sony Corporation ("Sony") to jointly develop digital
television technologies for cable television devices and high definition
television ("HDTV") products. In addition, the Company plans to incorporate
Sony's Home Network architecture into its advanced digital set-top terminals.
Sony has also agreed to purchase 7.5 million newly issued shares of Common Stock
at a purchase price of $25.00 per share. These transactions are all subject to
the completion of definitive agreements.
 
    - CISCO SYSTEMS, INC.  In anticipation of mass distribution of standardized
cable modems, the Company has entered into a working relationship with Cisco
Systems, Inc. ("Cisco Systems") to develop an interoperable DOCSIS-compliant
two-way cable modem network using the Company's cable modems.
 
    - STRATEGIC INVESTMENTS.  The Company has made investments in certain
companies that it believes bring strategic value in support of the Company's
business strategy. These investments include an approximately 5% interest in
Broadcom Corporation, a leading developer of highly integrated silicon solutions
that enable broadband transmission of video and high-speed data, and a 7.6%
interest in Wink Communications, Inc., a provider of an enhanced television
broadcasting system that adds interactivity and electronic commerce
opportunities to traditional television programming and advertising.
 
SELLING STOCKHOLDERS
 
    All of the shares of Common Stock being offered are being sold by certain

- ------------------------------
(a) Includes charges of $124 million ($79 million net-of-tax) which consist of
    costs related to the closure of various facilities, including the Company's
    satellite television manufacturing facility in Puerto Rico, severance and
    other employee separation costs, the write-down of certain assets to their
    estimated net realizable values and a $75 million charge to fully reserve
    for an advance made to the Partnership.
 
(b) Includes charges of $24 million ($18 million net-of-tax) reflecting
    restructuring costs related to dividing the Distributing Company's Taiwan
    operations between the Company and General Semiconductor and costs directly
    related to the Distribution.
 
(c) Includes charges of $110 million ($79 million net-of-tax) reflecting
    restructuring and other charges primarily related to the closure of various
    facilities, including the Company's satellite television manufacturing
    facility in Puerto Rico, severance and other employee separation costs, the
    write-down of certain assets to their estimated net realizable values and
    costs related to dividing the Distributing Company's Taiwan operations
    between the Company and General Semiconductor.
 
(d) Includes charges of $226 million ($145 million net-of-tax) reflecting Next
    Level Communications, a California corporation ("NLC"), litigation costs and
    other charges primarily related to the transition to the Company's
    next-generation digital products and the write-down of certain assets to
    their estimated net realizable values.
 
(e) Includes a charge of $140 million ($90 million net-of-tax) for purchased
    in-process technology in connection with the acquisition of NLC.
 
(f)  Includes an income tax benefit of $31 million, as a result of a reduction
    in a valuation allowance related to domestic deferred income tax assets.
 
(g) On a pro forma basis, selling, general and administrative expenses would be
    increased by $4 million for the six months ended June 30, 1997 and the year
    ended December 31, 1997 to eliminate the allocation of corporate expenses to
    CommScope, Inc. ("CommScope") and General Semiconductor, as such costs
    subsequent to the Distribution were no longer allocable.
 
(h) For the periods prior to the Distribution, interest expense -- net includes
    an allocation of interest expense from the Distributing Company which was
    allocated based upon the Company's net assets as a percentage of the total
    net assets of the Distributing Company. On a pro forma basis, interest
    expense would be reduced by $10 million and $11 million for the six months
    ended June 30, 1997 and the year ended December 31, 1997, respectively, to
    eliminate the aforementioned interest allocation and provide for interest
    expense on a net debt level of $100 million as of January 1, 1997.
 
(i)  Prior to the Distribution, the Company did not have its own capital
    structure, and pro forma per share information has been presented only for
    the years ended December 31, 1997 and 1996 and the six months ended June 30,
    1997. The pro forma earnings (loss) per share was calculated by dividing the
    net income (loss) by the pro forma weighted-average number of shares
    outstanding. The pro forma weighted-average number of shares outstanding
    used for the year ended December 31, 1996 and the six months ended June 30,
    1997 equaled the number of common shares issued and common equivalent
    shares, if dilutive, existing on the date of the Distribution, and for the
    year ended December 31, 1997, included the number of common shares issued on
    the date of the Distribution plus the actual share activity during the
    period subsequent to the Distribution.

    In addition to the matters described in the documents incorporated by
reference herein, the following risk factors should be considered by prospective
purchasers of the Common Stock offered hereby:
 
FACTORS RELATING TO THE DISTRIBUTION
 
    In a transaction that was consummated on July 28, 1997, the Distributing
Company (i) transferred all the assets and liabilities relating to the
manufacture and sale of broadband communications products used in the cable
television, satellite, and telecommunications industries to the Company (which
was then named "NextLevel Systems, Inc." and was a wholly-owned subsidiary of
the Distributing Company) and transferred 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 and (ii) then distributed all of the
outstanding shares of capital stock of each of the Company and CommScope to its
stockholders in the Distribution. Immediately following the Distribution, the
Distributing Company changed its corporate name to "General Semiconductor,
Inc.". Effective February 2, 1998, the Company changed its corporate name from
"NextLevel Systems, Inc." to "General Instrument Corporation".
 
    The Distribution Agreement, dated as of June 12, 1997, among the Company,
CommScope and the Distributing Company (the "Distribution Agreement") and
certain other agreements executed in connection with the Distribution
(collectively, the "Ancillary Agreements") allocate among the Company,
CommScope, and General Semiconductor and their respective subsidiaries
responsibility for various indebtedness, liabilities and obligations. It is
possible that a court would disregard this contractual allocation of
indebtedness, liabilities and obligations among the parties and require the
Company or its subsidiaries to assume responsibility for obligations allocated
to another party, particularly if such other party were to refuse or was unable
to pay or perform any of its allocated obligations.
 
    Pursuant to the Distribution Agreement and certain of the Ancillary
Agreements, the Company has agreed to indemnify the other parties (and certain
related persons) from and after consummation of the Distribution with respect to
certain indebtedness, liabilities and obligations, which indemnification
obligations could be significant.
 
    Although the Distributing Company has received a favorable ruling from the
Internal Revenue Service, if the Distribution were not to qualify as a tax free
spin-off (either because of the nature of the Distribution or because of events
occurring after the Distribution) under Section 355 of the Internal Revenue Code
of 1986, as amended, then, in general, a corporate tax would be payable by the
consolidated group of which the Distributing Company was the common parent based
upon the difference between the fair market value of the stock distributed and
the Distributing Company's adjusted basis in such stock. The corporate level tax
would be payable by General Semiconductor and could substantially exceed the net
worth of General Semiconductor. However, under certain circumstances, the
Company and CommScope have agreed to indemnify General Semiconductor for such
tax liability. In addition, under the consolidated return rules, each member of
the consolidated group (including the Company and CommScope) is severally liable
for such tax liability.
 
DEPENDENCE OF THE COMPANY ON THE CABLE TELEVISION INDUSTRY AND CABLE TELEVISION
  CAPITAL SPENDING
 
    The majority of the Company's revenues come from sales of systems and
equipment to the cable television industry. Demand for these products depends
primarily on capital spending by cable television system operators for
constructing, rebuilding or upgrading their systems. The amount of this capital
spending, and therefore the Company's sales and profitability, may be affected
by a variety of factors, including general economic conditions, the continuing
trend of cable system consolidation
 
                                       11
<PAGE>
within the industry, the financial condition of domestic cable television system
operators and their access to financing, competition from DTH, satellite,
wireless television providers and telephone companies offering video
programming, technological developments that impact the deployment of equipment
and new legislation and regulations affecting the equipment used by cable
television system operators and their customers. There can be no assurance that
cable television capital spending will increase from historical levels or that
existing levels of cable television capital spending will be maintained.
 
    Although the domestic cable television industry is comprised of thousands of
cable systems, a small number of MSOs own a majority of cable television systems
and account for a significant portion of the capital expenditures made by cable
television system operators. The loss of business from a significant MSO could
have a material adverse effect on the business of the Company.
 
THE IMPACT OF REGULATION AND GOVERNMENT ACTION
 
    In recent years, cable television capital spending has been affected by new
legislation and regulation, on the federal, state and local level, and many
aspects of such regulation are currently the subject of judicial proceedings and
administrative or legislative proposals. During 1993 and 1994, the Federal
Communications Commission (the "FCC") adopted rules under the Cable Television
Consumer Protection and Competition Act of 1992 (the "1992 Cable Act"),
regulating rates that cable television operators may charge for lower tiers of
service and generally not regulating the rates for higher tiers of service. In
1996, the Telecommunications Act of 1996 (the "Telecom Act") was enacted to
eliminate certain governmental barriers to competition among local and long
distance telephone, cable television, broadcasting and wireless services. The
FCC is continuing its implementation of the Telecom Act which, when fully
implemented, may significantly impact the communications industry and alter
federal, state and local laws and regulations regarding the provision of cable
and telephony services. Among other things, the Telecom Act eliminates
substantially all restrictions on the entry of telephone companies and certain
public utilities into the cable television business. Telephone companies may now
enter the cable television business as traditional cable operators, as common
carrier conduits for programming supplied by others, as operators of wireless
distribution systems, or as hybrid common carrier/cable operator providers of
programming on so-called "open video systems." The economic impact of the 1992
Cable Act, the Telecom Act and the rules thereunder on the cable television
industry and the Company is still uncertain.
 
    On June 24, 1998, the FCC released a Report and Order entitled IN THE MATTER
OF IMPLEMENTATION OF SECTION 304 OF THE TELECOMMUNICATIONS ACT OF 1996 --
COMMERCIAL AVAILABILITY OF NAVIGATION DEVICES (the "Retail Sales Order"), which
promulgates rules providing for the commercial availability of navigation
devices, including set-top devices and other consumer equipment, used to receive
video signals and other services from multichannel video programming
distributors ("MVPDs"), including cable television system operators. The Retail
Sales Order mandates that (i) subscribers have a right to attach any compatible
navigation device to an MVPD system regardless of its source and (ii) service
providers are prohibited from taking actions which would prevent navigation
devices that do not perform conditional access functions from being made
available by retailers, manufacturers, or other affiliated vendors. To
accomplish subscribers' right to attach, the FCC has ordered that (i) MVPDs must
provide technical information concerning interface parameters necessary to
permit navigation devices to operate with their systems; (ii) MVPDs must
separate out security functions from non-security functions by July 1, 2000; and
(iii) after January 1, 2005, MVPDs may not provide new navigation devices for
sale, lease or use that perform both conditional access functions and other
functions in a single integrated device.
 
    Unless modified or overturned, the Retail Sales Order will require set-top
device manufacturers, such as the Company, to develop a separate security module
to be available for sale to other manufacturers who want to build set-top
devices, as well as ultimately prevent the Company from offering set-top devices
in which the security and non-security functions are integrated. In addition,
the
 
                                       12
<PAGE>
Retail Sales Order may require the Company to offer its set-top devices through
retail distribution channels, an area in which the Company has limited
experience. The competitive impact of the Retail Sales Order is still uncertain,
and there can be no assurance that the Company will be able to compete
successfully with other consumer electronics manufacturers interested in
manufacturing set-top devices, many of which have greater resources and retail
sales experience than the Company.
 
    In February 1998, PRIMESTAR, the nation's second largest provider of
satellite television entertainment, entered into agreements with the Company,
pursuant to which the Company will manufacture integrated receiver decoders for
PRIMESTAR's planned high-power retail and wholesale service. Offering a
high-power service would enable PRIMESTAR to provide expanded channel capacity
and smaller receiving dishes to its subscribers. As a result of a pending
Department of Justice proceeding seeking to block PRIMESTAR's acquisition of
high-powered satellites from American Sky Broadcasting LLC ("ASkyB"), there is
uncertainty concerning PRIMESTAR's ability to provide this proposed service.
There can be no assurance that PRIMESTAR will ultimately gain governmental
approval to acquire the ASkyB assets or that it will be able to secure another
high-powered orbital slot, and accordingly, there can be no assurance that the
Company will realize the benefits of its agreement with PRIMESTAR.
 
    There can be no assurance that future legislation, regulations or government
action will not have a material adverse effect on the operations and financial
condition of the Company.
 
TELECOMMUNICATIONS INDUSTRY COMPETITION AND TECHNOLOGICAL CHANGES AFFECTING THE
  COMPANY
 
    The Company will be significantly affected by the competition among cable
television system operators, satellite television providers and telephone
companies to provide video, voice and data/Internet services. In particular,
although cable television operators have historically provided television
services to the majority of U.S. households, DTH satellite television has
attracted a growing number of subscribers and the regional telephone companies
have begun to offer competing cable and wireless cable services. This
competitive environment is characterized by rapid technological changes,
particularly with respect to developments in digital compression and broadband
access technology.
 
    The Company believes that, as a result of its development of new products
based on emerging technologies and the diversity of its product offerings, it is
well positioned to supply each of the cable, satellite and telephony markets.
The future success of the Company, however, will be dependent on its ability to
market and deploy these new products successfully and to continue to develop and
timely exploit new technologies and market opportunities both in the United
States and internationally. There can be no assurance that the Company will be
able to continue to successfully introduce new products and technologies, that
it will be able to deploy them successfully on a large-scale basis or that its
technologies and products will achieve significant market acceptance. The future
success of the Company will also be dependent on the ability of cable and
satellite television operators to successfully market the services provided by
the Company's advanced digital terminals to their customers. Further, there can
be no assurance that the development of products using new technologies or the
increased deployment of new products will not have an adverse impact on sales by
the Company of certain of its other products. In addition, because of the
competitive environment and the nature of the Company's business, there have
been and may continue to be claims by third parties asserting their intellectual
property rights and challenging the Company's ability to deploy new
technologies.
 
COMPETITION
 
    The Company's products and services compete with those of a substantial
number of foreign and domestic companies, some with greater resources, financial
or otherwise, than the Company, and the rapid technological changes occurring in
the Company's markets are expected to lead to the entry of new competitors. The
Company's ability to anticipate technological changes and to introduce enhanced
 
                                       13
<PAGE>
products on a timely basis will be a significant factor in the Company's ability
to expand and remain competitive. Existing competitors' actions and new entrants
may have an adverse impact on the Company's sales and profitability. For a
discussion of competitive factors regarding retail consumer electronic
manufacturers see "--The Impact of Regulation and Government Action". The
Company believes that it enjoys a strong competitive position because of its
large installed cable television equipment base, its strong relationships with
the major MSOs, its technological leadership and new product development
capabilities, and the likely need for compatibility of new technologies with
currently installed systems. There can be no assurance, however, that
competitors will not be able to develop systems compatible with, or that are
alternatives to, the Company's proprietary technology or systems.
 
INTERNATIONAL OPERATIONS; FOREIGN CURRENCY RISKS
 
    U.S. broadband system designs and equipment are being employed in
international markets, where cable television penetration is low. In addition,
the Company is developing new products to address international market
opportunities. However, the impact of the economic crises in Asia and Latin
America has significantly affected the Company's results in these markets. There
can be no assurance that international markets will rebound to historical levels
or that such markets will continue to develop or that the Company will receive
additional contracts to supply systems and equipment in international markets.
 
    International shipments of certain of the Company's products require export
licenses issued by the U.S. Department of Commerce prior to shipment in
accordance with U.S. export control regulations. The Company has made a
voluntary disclosure to the U.S. Department of Commerce with respect to a number
of violations by the Company of these export control regulations. While the
Company does not expect these violations to have a material adverse effect on
the Company's operations or financial condition, there can be no assurance that
these violations will not result in the imposition of sanctions or restrictions
on the Company.
 
    A significant portion of the Company's products are manufactured or
assembled in Taiwan and Mexico. In addition, the Company's operations are
expanding into new international markets. These foreign operations are subject
to the usual risks inherent in situating operations abroad, including risks with
respect to currency exchange rates, economic and political destabilization,
restrictive actions by foreign governments, nationalizations, the laws and
policies of the United States affecting trade, foreign investment and loans, and
foreign tax laws. The Company's cost-competitive status relative to other
competitors could be adversely affected if the New Taiwan dollar or another
relevant currency appreciates relative to the U.S. dollar.
 
CERTAIN RESTRICTIONS UNDER CREDIT FACILITIES
 
    The Credit Agreement dated as of July 23, 1997, as amended (the "Credit
Agreement"), among the Company, certain banks, and The Chase Manhattan Bank, as
Administrative Agent, contains certain restrictive financial and operating
covenants, including, among others, requirements that the Company satisfy
certain financial ratios. The failure of the Company to satisfy such covenants
could cause the Company to be unable to borrow under the Credit Agreement and
would cause the Company to seek alternative sources of working capital financing
and, depending upon the Company's financial condition at such time, could have a
material adverse effect on the operations and financial condition of the
Company.

- ------------------------------
 
(a) Includes charges of $124 million ($79 million net-of-tax) which consist of
    costs related to the closure of various facilities, including the Company's
    satellite television manufacturing facility in Puerto Rico, severance and
    other employee separation costs, the write-down of certain assets to their
    estimated net realizable values and a $75 million charge to fully reserve
    for an advance made to the Partnership.
 
(b) Includes charges of $24 million ($18 million net-of-tax) reflecting
    restructuring costs related to dividing the Distributing Company's Taiwan
    operations between the Company and General Semiconductor and costs directly
    related to the Distribution.
 
(c) Includes charges of $110 million ($79 million net-of-tax) reflecting
    restructuring and other charges primarily related to the closure of various
    facilities, including the Company's satellite television manufacturing
    facility in Puerto Rico, severance and other employee separation costs, the
    write-down of certain assets to their estimated net realizable values and
    costs related to dividing the Distributing Company's Taiwan operations
    between the Company and General Semiconductor.
 
(d) Includes charges of $226 million ($145 million net-of-tax) reflecting NLC's
    litigation costs and other charges primarily related to the transition to
    the Company's next-generation digital products and the write-down of certain
    assets to their estimated net realizable values.
 
(e) Includes a charge of $140 million ($90 million net-of-tax) for purchased
    in-process technology in connection with the acquisition of NLC.
 
(f)  Includes an income tax benefit of $31 million, as a result of a reduction
    in a valuation allowance related to domestic deferred income tax assets.
 
(g) On a pro forma basis, selling, general and administrative expenses would be
    increased by $4 million for the six months ended June 30, 1997 and the year
    ended December 31, 1997 to eliminate the allocation of corporate expenses to
    CommScope and General Semiconductor, as such costs subsequent to the
    Distribution were no longer allocable.
 
(h) For the periods prior to the Distribution, interest expense -- net includes
    an allocation of interest expense from the Distributing Company which was
    allocated based upon the Company's net assets as a percentage of the total
    net assets of the Distributing Company. On a pro forma basis, interest
    expense would be reduced by $10 million and $11 million for the six months
    ended June 30, 1997 and the year ended December 31, 1997, respectively, to
    eliminate the aforementioned interest allocation and provide for interest
    expense on a net debt level of $100 million as of January 1, 1997.
 
(i)  Prior to the Distribution, the Company did not have its own capital
    structure, and pro forma per share information has been presented only for
    the years ended December 31, 1997 and 1996 and the six months ended June 30,
    1997. The pro forma earnings (loss) per share was calculated by dividing the
    net income (loss) by the pro forma weighted-average number of shares
    outstanding. The pro forma weighted-average number of shares outstanding
    used for the year ended December 31, 1996 and the six months ended June 30,
    1997 equaled the number of common shares issued and common equivalent
    shares, if dilutive, existing on the date of the Distribution, and for the
    year ended December 31, 1997, included the number of common shares issued on
    the date of the Distribution plus the actual share activity during the
    period subsequent to the Distribution.
 
(j)  Prior to the Distribution, the Company participated in the Distributing
    Company's cash management program. To the extent the Company generated
    positive cash, such amounts were remitted to the Distributing Company. To
    the extent the Company experienced temporary cash needs for working capital
    purposes or capital expenditures, such funds were historically provided by
    the Distributing Company.  Accordingly, for the dates presented prior to the
    Distribution, no cash or debt balances existed.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION OF THE COMPANY'S FINANCIAL CONDITION AND RESULTS OF
OPERATIONS SHOULD BE READ IN CONJUNCTION WITH THE COMPANY'S CONSOLIDATED
FINANCIAL STATEMENTS INCORPORATED BY REFERENCE IN THIS PROSPECTUS.
 
COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 1998 AND JUNE 30, 1997
 
    NET SALES.  Net sales for the three months ended June 30, 1998 ("Second
Quarter 1998") were $489 million compared to $450 million for the three months
ended June 30, 1997 ("Second Quarter 1997"), an increase of $39 million, or 9%.
Net sales for the six months ended June 30, 1998 were $905 million compared to
$858 million for the six months ended June 30, 1997, an increase of $47 million,
or 5%. The increases in net sales for the three and six month periods reflect
increased sales of digital cable systems, partially offset by lower sales of
analog cable terminals and satellite systems for private and commercial
networks. Analog and digital products each represented approximately 50% of
total sales of the Company for the six months ended June 30, 1998, compared to
approximately 63% and 37%, respectively, for the six months ended June 30, 1997.
 
    Worldwide broadband sales (consisting of digital and analog cable and
wireless television systems and network transmission systems) of $380 million
and $689 million for Second Quarter 1998 and for the six months ended June 30,
1998, respectively, increased $61 million, or 19%, and $71 million, or 11%,
respectively, from the comparable 1997 periods primarily as a result of
increased U.S. sales volume of digital cable terminals and headends, partially
offset by the expected decline in sales of basic analog cable network systems.
These sales reflect the increasing commitment of cable television operators to
deploy state-of-the-art digital and interactive advanced analog systems in order
to offer advanced entertainment, interactive services and Internet access to
their customers. During the Second Quarter 1998 and Second Quarter 1997, net
broadband sales in the U.S. were 83% and 70%, respectively, combined U.S. and
Canadian sales were 84% and 73%, respectively, and all other international sales
were 16% and 27%, respectively, of total worldwide broadband sales. For the six
months ended June 30, 1998 and 1997, net broadband sales in the U.S. were 82%
and 69%, respectively, combined U.S. and Canadian sales were 84% and 73%,
respectively, and all other international sales were 16% and 27%, respectively,
of total worldwide broadband sales.
 
    Worldwide satellite sales of $109 million and $216 million for Second
Quarter 1998 and the six months ended June 30, 1998, respectively, decreased $22
million, or 17%, and $24 million, or 10%, respectively, from the comparable 1997
periods primarily as a result of lower private and commercial network sales.
During the Second Quarter 1998 and Second Quarter 1997, net satellite sales in
the U.S. were 96% and 75%, respectively, combined U.S. and Canadian sales were
96% and 85%, respectively, and all other international sales were 4% and 15%,
respectively, of total worldwide satellite sales. For the six months ended June
30, 1998 and 1997, net satellite sales in the U.S. were 95% and 79%,
respectively, combined U.S. and Canadian sales were 98% and 86%, respectively,
and all other international sales were 2% and 14%, respectively, of total
worldwide satellite sales.
 
    The decrease in broadband and satellite international sales during the 1998
periods was experienced in all international regions. The largest decreases in
sales during the first half of 1998 were experienced in the Asia/Pacific and
Latin American regions and there can be no assurance that international sales
will return to 1997 levels in the near term.
 
    TCI and Time Warner, including affiliates, each represented approximately
14% of the revenues of the Company for the year ended December 31, 1997. For the
six months ended June 30, 1998, TCI, PRIMESTAR and Time Warner accounted for
approximately 24%, 14% and 11% of total Company sales, respectively.
 
                                       19
<PAGE>
    GROSS PROFIT.  Gross profit of $141 million and $234 million for Second
Quarter 1998 and the six months ended June 30, 1998, respectively, increased $23
million, or 20%, and $3 million, or 1%, respectively, from the comparable 1997
periods. Gross profit was 29% and 26% of sales for Second Quarter 1998 and the
six months ended June 30, 1998, respectively, compared to 26% and 27%,
respectively, for the comparable 1997 periods. Gross profit for the six months
ended June 30, 1998 included $27 million of charges recorded in the first
quarter of 1998, primarily related to severance and other employee separation
costs, costs associated with the closure of various facilities and the write-
down of certain assets to their net realizable values. Gross profit for Second
Quarter 1997 and the six months ended June 30, 1997 included $16 million and $18
million, respectively, of charges for employee costs related to dividing the
Distributing Company's Taiwan operations between the Company and General
Semiconductor. Gross profit increases primarily reflect increased sales levels.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
("SG&A") expense was $46 million and $102 million for the Second Quarter 1998
and the six months ended June 30, 1998, respectively, compared to $52 million
and $95 million, respectively, for the comparable 1997 periods. SG&A expense as
a percentage of sales was 9% and 11% for the Second Quarter 1998 and the six
months ended June 30, 1998, respectively, and 12% and 11%, respectively, for the
1997 periods. SG&A spending for the six months ended June 30, 1998 included $13
million of charges 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. SG&A
spending for the Second Quarter 1997 and the six months ended June 30, 1997
included $6 million of charges primarily for legal and other professional fees
directly related to the Distribution. SG&A spending for the 1997 periods also
included SG&A expenses related to NLC.
 
    RESEARCH AND DEVELOPMENT.  Research and development ("R&D") expense was $42
million and $158 million for the Second Quarter 1998 and six months ended June
30, 1998, respectively, compared to $50 million and $101 million, respectively,
for the comparable 1997 periods. R&D expense for the six months ended June 30,
1998 included a $75 million charge to fully reserve the Note (as defined below
under "--Liquidity and Capital Resources"). R&D spending in 1998 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 EXPENSE--NET.  Other expense was $1 million and $10 million for the
Second Quarter 1998 and the six months ended June 30, 1998, respectively,
compared with $1 million and $2 million, respectively, for the comparable 1997
periods. Other expense increased in the first half of 1998 from the comparable
1997 period primarily due to the Company's equity interest in the Partnership's
loss, which includes the BROADBAND TECHNOLOGIES, INC. V. GENERAL INSTRUMENT
CORP. settlement and compensation expense related to key executives of an
acquired company, partially offset by a gain on the sale of a portion of the
Company's investment in Ciena Corporation and settlement of an insurance claim.
 
    INTEREST EXPENSE--NET.  Net interest expense for the three and six months
ended June 30, 1997 represents an allocation of interest expense from the
Distributing Company and was allocated based upon the Company's net assets as a
percentage of the total net assets of the Distributing Company for the period
prior to the date of the Distribution. Net interest expense allocated to the
Company was $6 million and $14 million for the Second Quarter 1997 and for the
six months ended June 30, 1997, respectively. Subsequent to July 25, 1997, the
date of the Distribution, net interest represents actual net interest expense
incurred by the Company.
 
    Pro forma interest expense for the Second Quarter 1997 and the six months
ended June 30, 1997 includes a reduction of interest expense of $5 million and
$10 million, respectively, to reflect an assumed net debt level of $100 million
at January 1, 1997.
 
                                       20
<PAGE>
    INCOME TAXES.  Through the date of the Distribution, income taxes were
determined as if the Company had filed separate tax returns under its existing
structure for the periods presented. Accordingly, future tax rates could vary
from the historical effective tax rates depending on the Company's future tax
elections. The Company recorded a provision for income taxes of $18 million and
a benefit for income taxes of $14 million for the Second Quarter 1998 and the
six months ended June 30, 1998, respectively, and a provision for income taxes
of $4 million and $8 million, respectively, for the comparable 1997 periods
based upon the expected annual effective tax rate.
 
COMPARISON OF THE YEAR ENDED DECEMBER 31, 1997 WITH THE YEAR ENDED DECEMBER 31,
  1996
 
    NET SALES.  Net sales for the year ended December 31, 1997 were $1,764
million compared to $1,756 million for the year ended December 31, 1996. Net
sales in 1997 when compared to 1996 reflect higher sales of digital cable
television systems and interactive advanced analog television systems, offset by
lower sales of basic analog cable television systems, cable transmission network
systems, digital satellite receivers and private/commercial network satellite
systems. Analog and digital products represented 58% and 42%, respectively, of
total sales in 1997 compared to 67% and 33%, respectively, of total sales in
1996.
 
    Worldwide broadband sales (consisting of digital and analog cable and
wireless television systems and transmission network systems) increased $112
million, or 10%, to $1,293 million in 1997 primarily as a result of increased
U.S. sales volumes of digital cable television terminals and headends and CFT
advanced analog cable television terminals, partially offset by lower sales of
basic analog cable and transmission network systems. These sales reflect the
increasing commitment of U.S. cable television operators to deploy
state-of-the-art digital and interactive advanced analog systems in order to
offer advanced entertainment, interactive services and Internet access to their
customers. International broadband sales increased $11 million, or 3%, to $403
million in 1997 and represented 31% of worldwide broadband sales in 1997
compared to 33% in 1996. Worldwide satellite sales of $462 million for the year
ended December 31, 1997 decreased $113 million, or 20%, from 1996 primarily as a
result of lower sales volumes of digital satellite receivers to PRIMESTAR.
International satellite sales increased $41 million, or 59%, to $110 million in
1997, primarily as a result of higher Canadian sales. International satellite
sales represented 24% of worldwide satellite sales in 1997 compared to 12% in
1996. NLC's sales were $9 million in 1997.
 
    GROSS PROFIT.  Gross profit increased $22 million, or 5%, to $428 million in
1997 from $406 million in 1996 and was 24% of sales in 1997 compared to 23% in
1996. Gross profit for the year ended December 31, 1997 was reduced by $84
million of charges primarily related to the closure of the Company's Puerto Rico
satellite manufacturing facility, employee costs related to dividing the
Distributing Company's Taiwan operations between the Company and General
Semiconductor and the write-down of inventories to their estimated net
realizable values. Gross profit for the year ended December 31, 1996 was reduced
by $71 million of charges primarily related to the write-down of inventories to
their estimated net realizable values and the accrual of upgrade and product
warranty liabilities in connection with the transition to the Company's
next-generation digital products. The higher gross profit and gross profit
margin in 1997 resulted from higher production volumes and ongoing cost
reduction programs on digital and advanced analog products.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  SG&A expense was $215 million in 1997
compared to $174 million in 1996 and was 12% of sales in 1997 compared to 10% in
1996. SG&A expense for the year ended December 31, 1997 included $28 million of
charges related to severance and other employee separation costs, costs
associated with the closure of various facilities and legal and other
professional fees incurred in connection with the Distribution, partially offset
by a $5 million credit related to the collection of certain receivables
previously considered to be uncollectible. SG&A expense in 1996 included $14
million of charges primarily related to employee separation costs due to the
Distributing
 
                                       21
<PAGE>
Company's plan to separate into three independent companies, the write-down of
various fixed assets to their estimated net realizable values and the settlement
of a litigation matter. SG&A base spending was also greater in 1997 than in 1996
as a result of increased marketing and field support for NLC's NLevel(3)
telephony system and the Company's digital video broadcasting ("DVB") compliant
digital satellite products and increased sales force, field support and
marketing in international cable and satellite television markets.
 
    RESEARCH AND DEVELOPMENT.  R&D expense increased $10 million, or 5%, to $208
million in 1997 from $198 million in 1996 and was 12% of sales in 1997 compared
to 11% in 1996. R&D expense for the year ended December 31, 1997 included $9
million of charges primarily related to the write-down of certain assets used in
R&D activities to their estimated net realizable values. R&D spending in 1997
reflects: the continued development of next-generation products, including
high-speed data systems for cable and telephone networks, switched-digital
access systems for fiber and twisted-pair networks, as well as the modification
of existing products for international markets; the continued development of
enhanced addressable analog terminals and advanced digital systems for cable and
satellite television distribution; and product development and international
expansion through strategic alliances. In addition, in 1997, the Company
remained focused on reducing costs and enhancing the features of its digital
cable and satellite television systems.
 
    OTHER INCOME (EXPENSE)--NET.  Other income of $6 million for the year ended
December 31, 1997 predominately reflects net investment gains, primarily from
the sale of a portion of the Company's investment in Ciena Corporation.
 
    INTEREST INCOME (EXPENSE)--NET.  Net interest expense represents an
allocation of interest expense from the Distributing Company based upon the
Company's net assets as a percentage of the total net assets of the Distributing
Company through July 25, 1997, the date of the Distribution. Net interest
expense allocated to the Company was $15 million for the year ended December 31,
1997 compared to $26 million in 1996. Subsequent to July 25, 1997, net interest
income primarily represents actual interest earned on the Company's net cash
balance and the net reversal of accrued interest subsequent to receiving a
revised final judgment in the suit brought against NLC and the founders of NLC
by DSC Communications Corporation and DSC Technologies Corporation.
 
    On a pro forma basis, interest income was $6 million in 1997 compared to
interest expense of $8 million in 1996.
 
    INCOME TAXES.  Through the date of the Distribution, income taxes were
determined as if the Company had filed separate tax returns under its then
existing structure for the periods presented. Accordingly, future tax rates
could vary from the historical effective tax rates depending on the Company's
future tax elections. The Company recorded a provision for income taxes of $6
million and a benefit for income taxes of $53 million for the years ended
December 31, 1997 and 1996, respectively. Excluding the restructuring and other
net charges recorded in 1997 and 1996, the effective tax rates were 38% and 36%,
respectively. The higher effective rate in 1997 resulted from a higher provision
for state income taxes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Prior to the Distribution, the Company participated in the Distributing
Company's cash management program. To the extent the Company generated positive
cash, such amounts were remitted to the Distributing Company. To the extent the
Company experienced temporary cash needs for working capital purposes or capital
expenditures, such funds were historically provided by the Distributing Company.
At the date of the Distribution, $125 million of cash was transferred to the
Company.
 
    For the six months ended June 30, 1998 and 1997, cash provided by operations
was $35 million and $66 million, respectively. Cash provided by operations in
the first half of 1998 primarily reflects cash
 
                                       22
<PAGE>
generated from operations, partially offset by the funding provided to the
Partnership related to its R&D activities and payments related to the
restructuring. Cash provided by operations in the first half of 1997 primarily
represents cash generated by the broadband business, partially offset by
increased inventory levels to support business growth.
 
    At June 30, 1998 and December 31, 1997, working capital was $453 million and
$436 million, respectively. The Company believes that working capital levels are
adequate to support the growth of the digital business, however, there can be no
assurance that future industry-specific developments or general economic trends
will not continue to alter the Company's working capital requirements.
 
    During the six months ended June 30, 1998 and 1997, the Company invested $40
million and $37 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 $120 million. The Company's R&D expenditures
were $158 million (including the $75 million funding related to the
Partnership's R&D activities) and $101 million during the first six months of
1998 and the first six months of 1997, respectively. The Company expects total
R&D expenditures to approximate $245 million (including the $75 million funding
related to the Partnership) for the year ending December 31, 1998.
 
    The Company's Credit Agreement 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. None of the restrictions contained in
the Credit Agreement is expected to have a significant effect on the Company's
ability to operate. As of June 30, 1998, the Company was in compliance with all
financial and operating covenants contained in the Credit Agreement and had
available credit of $500 million.
 
    In January 1998, the Company announced that, subject to the completion of
definitive agreements, Sony will purchase 7.5 million new shares of Common Stock
of the Company for $188 million. See "Business--Strategic Partner and Customer
Relationships--Sony Corporation".
 
    In January 1998, the Company transferred the net assets, principally
technology, and the management and workforce of NLC to the Partnership in
exchange for approximately an 89% (subject to additional dilution) limited
partnership interest. Additionally, the Company advanced to the Partnership $75
million, utilizing available operating funds and borrowings under its Credit
Agreement, in exchange for a Partnership note (the "Note"). Since the repayment
of the Note is 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 fully reserve for the Note
concurrent with the funding. The Company has agreed to make an additional $50
million equity investment in the Partnership, expected to occur on or after
November 1, 1998, to fund the Partnership's growth and assist the Partnership in
meeting its forecasted working capital requirements.
 
    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 and
borrowings under the Credit Agreement. 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, 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 ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED
 
    SEGMENT REPORTING--In June 1997, Statement of Financial Accounting Standard
("SFAS") No. 131, "Disclosures about Segments of an Enterprise and Related
Information", was issued and is effective for fiscal periods beginning after
December 15, 1997. SFAS No. 131 establishes standards for the reporting of
information about operating segments, including related disclosures about
products and services, geographic areas and major customers, and requires the
reporting of selected information about operating segments in interim financial
statements. The Company is currently evaluating the disclosure requirements of
this statement and will include the necessary disclosures in the year-end
financial statements as required in the initial year of adoption.
 
    PENSION AND OTHER POSTRETIREMENT DISCLOSURES--In February 1998, the
Financial Accounting Standards Board ("FASB") issued SFAS No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits--an amendment of
FASB Statements No. 87, 88 and 106". This statement, which is effective for
fiscal years beginning after December 15, 1997, requires revised disclosures
about pension and other postretirement benefit plans.
 
    Since the above two statements revise only financial statement disclosures,
their adoption will not have any impact on the Company's consolidated financial
position, results of operations or cash flows.
 
    DERIVATIVE AND HEDGE ACCOUNTING--In June 1998, SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities", was issued and is effective for
fiscal years beginning after June 15, 1999. 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.
 
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 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 where cable penetration is low and demand for entertainment programming
is growing. However, management expects that demand in North America for its
basic 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.
 
FOREIGN EXCHANGE AND 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
 
                                       24
<PAGE>
selective hedging strategies to reduce the market risks from changes in exchange
rates. On a selective basis, the Company enters into contracts to hedge 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 June 30, 1998, a hypothetical 10% fluctuation in the exchange rate
of foreign currencies applicable to the Company, principally the New Taiwan and
Canadian dollars, would result in a net $2 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.
 
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 in the first half of 1998 in comparison to the prior year, and there
can be no assurance that international sales will increase to 1997 levels in the
near future. In order to support the Company's international product and
marketing strategies, it is currently expected that the Company will add
operations in foreign markets in the following areas, among others: customer
service, sales, finance, product warehousing and expansion of manufacturing
capacity at existing facilities. Although no assurance can be given, management
expects that the expansion of international operations will not require
significant increased levels of capital expenditures.
 
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 has identified and evaluated the changes to its computer systems
and products necessary to achieve a year 2000 date conversion, and required
conversion and testing efforts are currently underway and are expected to be
completed by mid 1999. The Company continues to communicate with its suppliers,
customers and others with which it does business to understand the impact of any
year 2000 issues on 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 an adverse effect on the Company. The Company does not
expect the cost of achieving year 2000 compliance will exceed $5 million.
Additionally, based on the current status of these efforts, the Company believes
that it will be able to manage its total year 2000 transition without any
material adverse effect on its business operations, products or financial
prospects.

BUSINESS STRATEGY
 
    The Company's strategy is to use its technological leadership in providing
secure broadband systems and equipment to enhance its leading position in its
traditional markets while expanding into new markets. This strategy is based on
the belief that (i) consumers in the United States and international markets
will continue to demonstrate an increasing demand for new information and
entertainment services and (ii) content and service providers will continue to
create new bandwidth-intensive video, voice and data applications. The Company's
management believes that these factors will generate a continuing need for
systems and equipment with greater capacity for all networks and architectures.
 
DEMAND FOR SYSTEMS AND EQUIPMENT SUPPORTING NEW BANDWIDTH INTENSIVE APPLICATIONS
 
    The Company expects the market for systems and equipment supporting new
bandwidth intensive applications to grow significantly as a result of the
availability of new information and entertainment services for consumers.
 
    - CABLE SYSTEM UPGRADES.  Cable operators are upgrading their systems to
provide for two-way capabilities and additional capacity in order to provide
advanced services such as Internet access, VOD and telephony. The cable
infrastructure, with its high capacity access into the home, is regarded as an
attractive network for the delivery of advanced communication and entertainment
services. The Company believes that the commercialization of advanced broadband
systems and equipment, which provide for greatly expanded channel capacity and
programming options, improved quality and security of signal transmission and
the capability of delivering enhanced features and services, presents a
significant opportunity for the Company. Recent developments in the cable and
telecommunications industries, including the announcement of a proposed merger
between AT&T and TCI, Microsoft's $1 billion investment in Comcast, and the
purchase of Marcus Cable and Charter by Paul Allen, a founder of Microsoft, are
expected to accelerate cable systems operator spending for these advanced
broadband systems to facilitate the offering of advanced services.
 
    - TELEPHONY DEVELOPMENTS.  At the same time as cable operators are upgrading
their systems to offer advanced services, Regional Bell Operating Companies and
other telecommunications companies are also seeking a cost-effective way to
deliver standard telephony and advanced services to the home, including
high-speed data/Internet, distance learning and video services. The Company
believes that this presents a significant opportunity for suppliers, such as the
Partnership, which provide integrated broadband access systems that enable these
services from a single access platform.
 
                                       26

THE COMPANY'S MARKET LEADERSHIP
 
    The Company has a leading position in providing systems and equipment to the
broadband communications market. Currently, the Company is a leading supplier to
16 of the 20 largest MSOs in the United States and believes that it has supplied
a majority of the addressable systems in use by cable television operators in
the United States and abroad.
 
    - LEADER OF COMMERCIALIZATION OF DIGITAL BROADBAND SYSTEMS.  The Company is
the leading supplier of interactive digital cable television systems. Through
June 30, 1998, the Company had shipped approximately 600 digital cable
television head-end systems, passing approximately 28 million homes, and over
1.4 million two-way interactive digital cable television set-top terminals to
broadband system operators. The Company has entered into definitive agreements,
with an estimated value of $4.5 billion, to supply approximately 15 million
digital set-top terminals to leading North American cable operators, with a
collective subscriber base of over 46 million, over the next three to five
years.
 
    During the second half of 1998 and during 1999, the Company expects to
introduce new two-way interactive set-top terminal models, including terminals
targeted at European and other international cable operators and a high-end
terminal that incorporates a built-in DOCSIS-compliant cable modem, IP and a
unique triple tuner architecture that will ultimately enable consumers to watch
television, surf the World Wide Web and talk on the telephone simultaneously.
 
    - THE WORLD LEADER IN ANALOG ADDRESSABILITY.  The Company is the world's
leading provider of addressable analog set-top systems. The Company's latest
two-way interactive advanced analog terminal provides cable operators with
Internet access, interactive programming guides, CD-quality music, NVOD,
supplemental sports and entertainment information and local
information-on-demand.
 
    - NEXT GENERATION TELEPHONY.  The Partnership, in which the Company has an
89% limited partnership interest, is a leading provider of the next generation
of integrated full service DLC and FTTC systems for the delivery of telephony,
video and data for local telephone companies. The Partnership's product,
NLevel(3), is designed to permit the cost effective delivery of a suite of
standard telephony and advanced services, including high-speed data/Internet,
distance learning, VOD and video telephony, to the home from a single access
platform. In July 1998, the Partnership was selected to supply DLC and FTTC
systems to U S West for the delivery of broadband video, high-speed
data/Internet, and basic telephone services. The Company has also contracted to
supply U S West with 450,000 broadband xDSL access lines and to supply Bell
Atlantic with 1,000,000 lines of telephone service. The Partnership is currently
deploying its NLevel(3) products pursuant to these contracts.
 
STRATEGIC PARTNER AND CUSTOMER RELATIONSHIPS
 
    The Company recently entered into several strategic relationships, including
equity investments in the Company by large MSOs, which are expected to provide a
strong foundation for future business development and to reinforce the Company's
position as a leading provider of the next generation of broadband
communications equipment and systems.
 
    - CABLE CUSTOMER EQUITY OWNERSHIP.  The Company has issued warrants to
purchase approximately 29 million shares of Common Stock to leading North
American cable system operators. These warrants were issued in connection with
the definitive agreements to supply approximately 15 million digital set-top
terminals to such operators. Included among the cable operators entitled to
exercise the warrants upon the purchase of set-top terminals from the Company
are TCI, Time Warner, MediaOne, Comcast, Cox, Adelphia, Shaw, Jones and Charter.
 
    - SET-TOP AUTHORIZATION SERVICES.  The Company issued 21,356,000 shares of
its Common Stock to an affiliate of TCI in connection with the Company's
acquisition of the set-top authorization services business that controls the
receipt of cable programming services delivered to subscribers by TCI's Headend
In The Sky. The Company now provides national authorization services throughout
the United
 
                                       27
<PAGE>
States to TCI, its affiliates and other operators, many with relatively small
individual systems that could not otherwise justify the initial capital
investment required to launch a local digital headend computer control system.
 
    - SONY CORPORATION.  The Company has announced plans to enter into a
strategic alliance with Sony to jointly develop digital television technologies
for cable television devices and HDTV products. In addition, the Company plans
to incorporate Sony's Home Network architecture into its advanced digital
set-top terminals. Sony has also agreed to purchase 7.5 million newly issued
shares of Common Stock at a purchase price of $25.00 per share. These
transactions are all subject to the completion of definitive agreements.
 
    - CISCO SYSTEMS, INC.  In anticipation of mass distribution of standardized
cable modems, the Company has entered into a working relationship with Cisco
Systems to develop an interoperable DOCSIS-compliant two-way cable modem network
using the Company's cable modems.
 
    - STRATEGIC INVESTMENTS.  The Company has made investments in certain
companies that it believes bring strategic value in support of the Company's
business strategy. These investments include an approximately 5% interest in
Broadcom Corporation, a leading developer of highly integrated silicon solutions
that enable broadband transmission of video and high-speed data, and a 7.6%
interest in Wink Communications, Inc., a provider of an enhanced television
broadcasting system that adds interactivity and electronic commerce
opportunities to traditional television programming and advertising.
 
BUSINESS UNITS
 
    The Company is presently organized into four strategic business units:
Digital Network Systems, Advanced Network Systems, Transmission Network Systems
and Satellite Data Network Systems.
 
    DIGITAL NETWORK SYSTEMS.  The Company is the world's leading supplier of
secure interactive digital cable television delivery systems. The principal
products of this business unit are: (i) individual network elements, including
consumer set-top terminals and various video, audio and data processing
equipment used in cable operators' headends; (ii) computer equipment, software
and services for securing programming content, downloading software applications
to consumer set-top terminals, authorizing individual subscriber services,
enabling network management and providing interfaces to cable operators' billing
systems; and (iii) system integration services for the custom assembly and test
of Company and third-party hardware and software elements.
 
    North American cable operators began deploying commercial services using the
Company's interactive digital delivery systems in 1996. As of June 30, 1998, the
Company had shipped approximately 600 digital headend systems throughout North
America, passing approximately 28 million homes, and over 1.4 million digital
cable and wireless set-top terminals. In addition, the Company's digital
business is in the early stages of expanding into regions beyond North America
such as Europe, the Middle East, Asia/Pacific and Latin America.
 
    Digital compression technology allows cable operators to provide 6 to 12
times the number of programs per traditional channel slot than is possible using
analog technology. Initial cable operator demand for the Company's digital
products has been the result of the cable operators' ability to offer additional
pay-per-view and other programming choices enabled by such digital compression
technology, the high quality of digital video/audio, electronic program guides
and the potential to offer a wide range of new interactive applications. Several
cable operators are now performing trials of some of these new interactive
applications such as true VOD, Internet access and e-mail. The Company's digital
products are designed with an open architecture so that these new interactive
software applications being developed by a number of third parties can be
downloaded over the cable network to set-top terminals already installed in
consumer homes.
 
                                       28
<PAGE>
    All of the Company's digital cable set-top terminals utilize the digital
transport stream and decode video compliant with the Motion Picture Experts
Group 2 ("MPEG-2") international standard and demodulate
Quadrature-Amplitute-Modulated signals compliant with International
Telecommunications Union international standards. The terminals and delivery
systems also use standards-based interactive communications protocols and the
Company's proprietary access control technology marketed under the
DigiCipher-Registered Trademark- II and MediaCipher-TM- brand names, as well as
decode Dolby Digital-Registered Trademark- audio. As of June 30, 1998, the
Company's digital terminal shipments have consisted of its DCT-1000 and DCT-1200
model cable terminals and DWT-1000 model wireless terminals. All of these
set-top products are two-way terminals capable of real-time, interactive
operation using either a built-in RF return modem or optional telephone return
modem. Additionally, all of these set-top products are compatible with the
existing installed base of the Company's set-top products. Such compatability
enhances security, reduces operating costs and improves bandwidth utilization.
 
    The Company expects to introduce new two-way interactive set-top terminal
models during the second half of 1998 and during 1999. The DVi-2000 model, which
includes DVB-compliant technologies such as Musicam-Registered Trademark- audio
decoding, is targeted at European and other international cable operators. The
DCT-2000 model is an evolution of the DCT-1000 and DCT-1200 product line that
includes a faster microprocessor, enhanced graphics and expanded application
memory. The DCT-5000+ model is a high-end terminal that incorporates a built-in
DOCSIS compliant cable modem, IP and a unique triple tuner architecture that
ultimately will enable consumers to watch television, surf the World Wide Web
and talk on a telephone simultaneously.
 
    The Company has completed definitive agreements with leading North American
cable operators to supply approximately 15 million digital set-top terminals,
consistent with the cable industry's OpenCable initiative, over the next three
to five years, with an estimated value of $4.5 billion. The Company has issued
warrants to purchase approximately 29 million shares of the Company's Common
Stock to these cable operators in connection with such agreements. Included
among the cable operators entitled to purchase set-top terminals from the
Company under these agreements are TCI, Time Warner, MediaOne, Comcast, Cox,
Adelphia, Shaw, Jones, Charter, Suburban Cable Company, Intermedia Cable and
Bresnan Communications Company, with a collective subscriber base of over 46
million.
 
    In July 1998, the Company completed its acquisition from affiliates of TCI
of certain physical assets and a license of associated intellectual property to
enable it to provide the set-top authorization services that control the receipt
of cable programming services delivered to subscribers by TCI's Headend In The
Sky. The Company issued 21,356,000 shares of its Common Stock to an affiliate of
TCI in exchange for this acquisition. The Company now provides national
authorization services throughout the United States to TCI, its affiliates and
other operators, many with relatively small individual systems that could not
otherwise justify the initial capital investment required to launch a local
digital headend computer control system. The Company continues to supply its
internally developed DAC-6000 model controller for local and regional
authorization systems solutions for individual operators with larger individual
subscriber bases.
 
    ADVANCED NETWORK SYSTEMS.  The Company is the world's leading provider of
addressable analog set-top systems which enable cable operator control and
subscriber access to a number of advanced entertainment services and features.
The principal products of this business unit are consumer set-top terminals and
the associated central office headend computer and processing equipment. Use of
these addressable systems enables operators to provide a suite of service
offerings, from pay-per-view and multiple tiers of programming services, through
advanced video, audio and data entertainment services.
 
    Beginning in early 1995, the Company began shipping its latest generation
CFT system, the CFT2200 interactive advanced analog system, adding a new level
of service offering to the prior analog platforms. The CFT2200 two-way
interactive advanced analog terminal provides cable operators with
 
                                       29
<PAGE>
the most complete set of functionality available today over an analog platform,
including Internet access, interactive programming guides, CD-quality music,
NVOD, supplemental sports and entertainment information and local
information-on-demand. The Company shipped approximately 1.6 million CFT
advanced analog terminals for the six months ended June 30, 1998 and
approximately 3.2 million CFT advanced analog terminals for the year ended
December 31, 1997.
 
    The Company provides addressable analog set-top systems throughout the
world, and is the market leader in North and South America, Europe, and Asia
with the CFT advanced platform. Market share in the U.S. analog addressable
market has exceeded 50% for the last several years, both in the traditional and
advanced product segments. While management expects that the Company's advanced
analog cable products will continue to meet cable and wireless operator demands
worldwide for several years, due to the anticipated increased availability and
use of digital cable products, the Company expects that demand in North America
for its traditional analog cable products will continue to decline.
 
    TRANSMISSION NETWORK SYSTEMS.  The Company's transmission products provide
end-to-end solutions that enable the transformation of the traditional cable
television network to a two-way, fiber-rich, high speed voice/video/data
network. Transmission products include headend signal processing equipment,
distribution amplifiers, fiber optic transmission equipment and passive
components for wired television distribution systems.
 
    The Company's management expects cable television operators in the United
States and abroad to continue to upgrade their basic networks and invest in new
system capacity primarily to compete with other television programming sources,
such as DTH, as well as to capitalize on the rapid growth in demand for
high-speed Internet access. Further opportunities exist internationally where
cable penetration is low and demand for both entertainment and high speed
internet access is growing.
 
    SATELLITE DATA NETWORK SYSTEMS.  The Company is a leading provider of
digital satellite television systems for programmers, DTH satellite network
providers and private networks for business communications and distance
learning. It offers a broad product line of digital compression and transmission
systems including MPEG-2, DVB and Advanced Television Systems Committee
compliant solutions. The Company is also a leader in the development of
high-speed data networks.
 
    DIGITAL AND ANALOG SATELLITE PRODUCTS.  The Company designs, manufactures
and sells analog and digital satellite uplink and downlink products for
commercial and consumer use. Using the Company's DigiCipher II digital
technology, commercial customers are able to compress their video, audio and
data transmissions resulting in significant cost savings over traditional analog
transmission. The Company also offers state-of-the-art network management and
access control products and services allowing program packagers to efficiently
and cost-effectively manage customer transactions and securely transmit their
programming to only authorized end-users. The Company is the leading
manufacturer of access control and scrambling and descrambling equipment used by
television programmers for the satellite distribution of proprietary
programming.
 
    The Company is the sole supplier of digital satellite receivers and digital
satellite encoders to DTH provider PRIMESTAR and a leading supplier of digital
satellite encoders for DTH provider DIRECTV-Registered Trademark-. The Company
is also a leading supplier of digital satellite systems to private networks for
such applications as business communications and distance learning.
 
    The analog satellite products of the Company are the exclusive systems for
the distribution of encrypted C-band (large dish) satellite-delivered
programming to cable television operators and large-diameter backyard satellite
dish owners. Sales of analog consumer descramblers have declined, as expected,
to minimal levels over the past two years, and are expected to continue to
decline as a result of the availability of competing digital satellite video
services. The Company introduced its first digital descramblers for the backyard
C-band market in 1997. This product, called 4DTV-Registered Trademark-, allows
C-band dish owners to take advantage of the wealth of digital programming now
being transmitted by satellite. There
 
                                       30

can be no assurance, however, as to the degree of market acceptance of this new
product. To date, significant quantities of 4DTV have not been shipped.
 
    HIGH SPEED DATA NETWORKS.  The Company's management believes that the rapid
growth in personal computer ownership and, in particular, usage of on-line and
Internet access services, has created a demand for increased data transmission
speeds. The Company's high-speed cable modem is capable of delivering
information through the cable television network at speeds significantly faster
than a traditional telephone modem, while delivering instructions and other
information upstream from the consumer over telephone lines. The Company has
become the first company to market cable modems with a major national computer
retailer--CompUSA. In addition, in anticipation of mass distribution of
standardized cable modems, the Company has entered into a working relationship
with Cisco Systems to develop an interoperable DOCSIS-compliant two-way cable
modem network using the Company's cable modems.
 
NEXT LEVEL COMMUNICATIONS, L.P.
 
    The Partnership is a leading provider of next-generation integrated full
service DLC and FTTC systems for the delivery of telephony, video and data for
local telephone companies, including Bell Atlantic and U S West. The
Partnership's product, NLevel(3), is designed to permit the cost effective
delivery of a suite of standard telephony and advanced services, including
high-speed data/Internet, distance learning, VOD and video telephony, to the
home from a single access platform.
 
    In the fourth quarter of 1996, NLC entered into an agreement with a
subsidiary of NYNEX Corporation, now Bell Atlantic, pursuant to which the
Partnership will supply its NLevel(3) system for one million lines of telephone
service in metropolitan New York City and Boston. Initial deployment for the
greater Boston area began in the first quarter of 1997. Bell Atlantic also has
options to extend its deployment of the NLevel(3) system to up to five million
lines. In the third quarter of 1997 NLC entered into an agreement with U S West,
pursuant to which the Partnership will supply its NLevel(3) system for 450,000
lines of broadband xDSL access. In addition, in July 1998, U S West selected the
Partnership to supply DLC and FTTC systems for the delivery of broadband video,
high-speed data/Internet, and basic telephone services.
 
    In January 1998, the Company transferred the business of NLC, including its
net assets, principally technology, and its management and workforce to the
Partnership in exchange for approximately an 89% limited partnership interest
(subject to additional dilution). An entity controlled by Spencer Trask & Co.,
the operating general partner, acquired approximately an 11% interest in the
Partnership and has the potential to acquire up to an additional 11% in the
future. Pursuant to an agreement entered into in July 1998, the Company has
agreed to make an additional $50 million equity investment in the Partnership,
expected to occur on or after November 1, 1998, which will increase its limited
partnership interest to more than 90%. Pursuant to the partnership agreement,
the operating general partner controls the Partnership and is responsible for
developing the business plan and infrastructure necessary to position the
Partnership as a stand-alone company.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    Pursuant to the Restated Certificate of Incorporation of the Company, the
authorized capital stock of the Company consists of (i) 400,000,000 shares of
Common Stock, of which 173,238,021 shares were issued and outstanding as of July
31, 1998 and (ii) 20,000,000 shares of preferred stock, $.01 par value per share
("Preferred Stock"), none of which were issued and outstanding as of such date.
 
COMMON STOCK
 
    Each holder of Common Stock is entitled to one vote for each share owned of
record on all matters submitted to a vote of stockholders. There are no
cumulative voting rights. Accordingly, the holders of a majority of the shares
voting for the election of directors can elect all the directors if they choose
to do so, subject to any voting rights of holders of Preferred Stock to elect
directors. Subject to the preferential rights of any outstanding series of
Preferred Stock, and to any restrictions on payment of dividends imposed by the
Credit Agreement, the holders of Common Stock will be entitled to such dividends
as may be declared from time to time by the Board from funds legally available
therefor, and will be entitled, after payment of all prior claims, to receive
PRO RATA all assets of the Company upon the liquidation, dissolution or winding
up of the Company. Holders of Common Stock have no redemption or conversion
rights or preemptive rights to purchase or subscribe for securities of the
Company. Certain provisions of the Certificate of Incorporation and By-Laws of
the Company have the effect of making more difficult an acquisition of control
of the Company in a transaction not approved by the Board of Directors.
 
PREFERRED STOCK
 
    The authorized capital stock of the Company includes 20,000,000 shares of
Preferred Stock, none of which are currently issued or outstanding. The Board is
authorized to divide the Preferred Stock into series and, with respect to each
series, to determine the preferences and rights and the qualifications,
limitations or restrictions thereof, including the dividend rights, conversion
rights, voting rights, redemption rights and terms, liquidation preferences,
sinking fund provisions, the number of shares constituting the series and the
designation of such series. The Board could, without stockholder approval, issue
Preferred Stock with voting and other rights that could adversely affect the
voting power of the holders of Common Stock and which could have certain
antitakeover effects.
 
    In connection with the Rights Plan (as defined below), the Board has
authorized 400,000 shares of Series A Junior Participating Preferred Stock (the
"Series A Preferred"). No shares of Series A Preferred are outstanding. For a
description of the rights, powers and preferences of the Series A Preferred, see
"--Rights Plan."
 
RIGHTS PLAN
 
    On June 10, 1997, the Board adopted a stockholder rights plan (the "Rights
Plan") pursuant to which one right (collectively, the "Rights") to purchase one
one-thousandth of a share of Series A Preferred would be distributed as a
dividend for each outstanding share of Common Stock at a purchase price of
$85.00 per one one-thousandth of a share of Series A Preferred, subject to
adjustment. The Rights are issuable on the terms and subject to the conditions
set forth in the Rights Plan. The Rights will expire no later than on the tenth
anniversary of the adoption of the Rights Plan in 2007. The Rights will be
exercisable on the earlier to occur of (i) the first date of public announcement
that a person or "group" (other than FLC Entities (as defined below) to the
extent FLC Entities, individually or as a group, beneficially own no more than
20% of the then outstanding Common Stock) has acquired beneficial ownership of
15% or more of the outstanding Common Stock (except pursuant to a Permitted
Offer, as defined in the Rights Plan) (an "Acquiring Person"); and (ii) ten
business days (or such later date as the Board may determine) following the
commencement of, or announcement of an intention to commence,
 
                                       37
<PAGE>
a tender offer or exchange offer the consummation of which would result in a
person or group becoming an Acquiring Person. On December 16, 1997, in
connection with the transactions (the "Transaction") between affiliates of TCI
and the Company, the Rights Plan was amended to provide that, for so long as (i)
TCI and its subsidiaries do not acquire beneficial ownership of any Common Stock
other than pursuant to the Transaction, or (ii) after giving effect to the
acquisition of the beneficial ownership of any Common Stock by TCI or a
subsidiary of TCI other than pursuant to the Transaction, the shares of Common
Stock beneficially owned by TCI and its subsidiaries in the aggregate do not
exceed 35% of the then outstanding shares of Common Stock, TCI and its
subsidiaries shall not constitute an Acquiring Person for purposes of the Rights
Plan. "FLC Entities" means Instrument Partners, MBO-IV, Theodore J. Forstmann,
Nicholas C. Forstmann, Wm. Brian Little, Steven B. Klinsky, Sandra J. Horbach,
Winston W. Hutchins and Thomas H. Lister and their affiliates and associates who
or which are considered as one person and references to the FLC Entities include
any or all such persons.
 
    If any person or group becomes an Acquiring Person or commences a tender
offer upon consummation of which such person or group would become an Acquiring
Person, each Right not owned by such Acquiring Person or certain related parties
would entitle its holder to purchase, at the Right's then current exercise
price, shares of Common Stock, or, in the discretion of the Board, the number of
one one-thousandths of a share of Series A Preferred having a value of twice the
Right's exercise price. In addition, if, after a person or group becomes an
Acquiring Person, the Company is involved in a merger or other business
combination transaction in which the holders of all of the outstanding Common
Stock immediately prior to the consummation of the transaction are not the
holders of the surviving corporation's voting power or more than 50% of the
Company's assets or earning power is sold or transferred, each Right will
entitle its holder to purchase common shares of the acquiring company having a
value equal to two times the Right's then current exercise price.
 
    The purchase price payable, and the shares issuable, upon exercise of the
Rights will be subject to adjustment from time to time as specified in the
Rights Plan. The Company will generally be entitled to redeem the Rights in
whole, but not in part, at $0.01 per Right at any time prior to the earlier to
occur of (i) a person becoming an Acquiring Person or (ii) expiration of the
Rights.
 
    Shares of Series A Preferred purchasable upon exercise of the Rights will
not be redeemable. Each Share of Series A Preferred will be entitled to a
minimum preferential quarterly dividend payment of $10.00 per share but, if
greater, will be entitled to an aggregate dividend per share of 1,000 times the
dividend declared per share of Common Stock. In the event of liquidation of the
Company, the holders of Series A Preferred will be entitled to a minimum
preferential liquidation payment of $100.00, provided that they will be entitled
to an aggregate payment per share of at least 1,000 times the aggregate payment
made per share of Common Stock. Each share of Series A Preferred will have one
thousand votes, voting together with the Common Stock. These rights are
protected by customary antidilution provisions. In the event that the amount of
accrued and unpaid dividends on the Series A Preferred is equivalent to at least
six full quarterly dividends, the holders of the Series A Preferred will have
the right, voting as a class, to elect two directors in addition to the
directors elected by the holders of Common Stock until all dividends in default
on the Series A Preferred have been paid in full and dividends for the current
dividend period declared and funds therefor set apart.

    Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
    The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at such
price less a concession of $         per share. The Underwriters may allow, and
such dealers may reallow, a concession not in excess of $         per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and other selling terms may from time to
time be varied by the representatives.
 
    The Selling Stockholders have granted the Underwriters an option exercisable
for 30 days after the date of this Prospectus to purchase, at the initial public
offering price per share less any underwriting discount as set forth on the
cover page of this Prospectus, up to an aggregate of 2,550,000 additional shares
of Common Stock to cover over-allotments, if any. If the Underwriters exercise
their over-allotment option, the Underwriters have severally agreed, subject to
certain conditions, to purchase approximately the same percentage thereof that
the number of shares to be purchased by each of them, as shown in the foregoing
table, bears to the 17,000,000 shares of Common Stock offered.
 
    The Company and the Selling Stockholders have agreed that, during the period
beginning from the date of this Prospectus and continuing to and including the
date 90 days after the date of the Prospectus, they will not offer, sell,
contract to sell or otherwise dispose of any securities of the Company which are
substantially similar to the shares of Common Stock or which are convertible
into or exchangeable for securities which are substantially similar to the
shares of Common Stock without the prior written consent of the representatives,
except for the shares of Common Stock offered in connection with the Offering,
certain permitted transactions by the Company and certain permitted transfers by
the Selling Stockholders who would agree to abide by the foregoing restrictions.
 
    The Company and the Selling Stockholders have agreed to indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act.
 
    In connection with the Offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the Offering. Stabilizing transactions consist of
certain bids or purchases for the purpose of preventing or retarding a decline
in the market price of the Common Stock; and syndicate short positions involve
the sale by the Underwriters of a greater number of shares of Common Stock than
they are required to purchase from the Selling Stockholders in the Offering. The
Underwriters also may impose a penalty bid, whereby selling
 
                                      U-1
<PAGE>
concessions allowed to syndicate members or other broker-dealers in respect of
the Common Stock sold in the Offering for their account may be reclaimed by the
syndicate if such shares of Common Stock are repurchased by the syndicate in
stabilizing or covering transactions. These activities may stabilize, maintain
or otherwise affect the market price of the Common Stock which may be higher
than the price that might otherwise prevail in the open market, and these
activities, if commenced, may be discontinued at any time. These transactions
may be effected on the NYSE, in the over-the-counter market or otherwise.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the Delaware General Corporation Law (the "DGCL") provides
that a corporation may indemnify directors and officers as well as other
employees and individuals against expenses (including attorneys' fees),
judgments, fines, and amounts paid in settlement in connection with specified
actions, suits, or proceedings whether civil, criminal, administrative, or
investigative, other than action by or in the right of the corporation (a
"derivative action"), if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard is
applicable in the case of derivative actions, except that indemnification only
extends to expenses (including attorneys' fees) incurred in connection with the
defense or settlement of such action, and the statute requires court approval
before there can be any indemnification where the person seeking indemnification
has been found liable to the corporation. The statute provides that it is not
exclusive of other indemnification that may be granted by a corporation's
charter, by-laws, disinterested director vote, stockholder vote, agreement, or
otherwise.
 
    Section 102(b)(7) of the DGCL permits a corporation to provide in its
certificate of incorporation that a director of the corporation shall not be
personally liable to the corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability for (i) any
breach of the director's duty of loyalty to the corporation or its stockholders,
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) payment of unlawful dividends or unlawful
stock purchases or redemptions, or (iv) any transaction from which the director
derived an improper personal benefit.
 
    Article Sixth of the Restated Certificate of Incorporation of the Company
provides that directors of the Company shall not, to the fullest extent
permitted by the DGCL, be liable to the Company or any of its stockholders for
monetary damages for any breach of fiduciary duty as director. The Certificate
of Incorporation of the Company also provides that if the DGCL is amended to
permit further elimination or
 
                                      II-1
<PAGE>
limitation of the personal liability of directors, then the liability of the
directors of the Company shall be eliminated or limited to the fullest extent
permitted by the DGCL as so amended.
 
    The Company has entered into agreements to indemnify its directors and
officers in addition to the indemnification provided for in its Restated
Certificate of Incorporation and Amended and Restated
By-Laws. These agreements, among other things, indemnify the Company's directors
and officers to the fullest extent permitted by Delaware law for certain
expenses (including attorneys' fees), liabilities, judgments, fines and
settlement amounts incurred by such person arising out of or in connection with
such person's service as a director or officer of the Company or an affiliate of
the Company.
 
    The Company will maintain directors' and officers' liability insurance which
will provide for payment, on behalf of the directors and officers thereof and
its subsidiaries, of certain losses of such persons (other than matters
uninsurable under law) arising from claims, including claims arising under the
Securities Act, for acts or omissions by such persons while acting as directors
or officers thereof and/or its subsidiaries, as the case may be.

ITEM 17. UNDERTAKINGS
 
    (a) The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
        (i)  to include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;
 
        (ii)  to reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high and of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement;
 
        (iii)  to include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;
 
provided, however, that the undertakings set forth in paragraphs (1)(i) and (ii)
above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the Commission by the registrant pursuant to Section
13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.
 
    (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
 
                                      II-3
<PAGE>
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.
 
    (c) The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.
 
    (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

         for such Selling Stockholder under the Custody Agreement or (B) the

         of this Agreement and of the various Custody Agreements; and actions
         taken by the Attorney-in-Fact pursuant to the Powers of Attorney shall
         be as valid as if such death, incapacity, termination, dissolution or
         other event had not occurred, regardless of whether or not the
         Custodian, the Attorney-in-Fact, or any of them, shall have received
         notice of such death, incapacity, termination, dissolution or other
         event.

such election shall have been exercised (to be adjusted by you so as to
eliminate fractional shares) determined by multiplying such number of Optional
Shares by a fraction the numerator of which is the maximum number of Optional
Shares which such Underwriter is entitled to purchase as set forth opposite the
name of such Underwriter in Schedule I hereto and the denominator of which is
the maximum number of Optional Shares that all of the Underwriters are entitled
to purchase hereunder.

         The Selling Stockholders, as and to the extent indicated in Schedule II
hereto, hereby grant, severally and not jointly, to the Underwriters the right
to purchase at their election up to _____ Optional Shares, at the purchase price
per share set forth in the paragraph above, for the sole purpose of covering
over-allotments in the sale of the Firm Shares. Any such election to purchase
Optional Shares shall be made in proportion to the number of Optional Shares to
be sold by each Selling Stockholder. Any such election to purchase Optional
Shares may be exercised only by written notice from you to the Attorney-in-Fact,
given within a period of 30 calendar days after the date of this Agreement and
setting forth the aggregate number of Optional Shares to be purchased and the
date on which such Optional Shares are to be delivered, as determined by you but
in no event earlier than the First Time of Delivery (as defined in Section 4
hereof) or, unless you and the Attorney-in-Fact otherwise agree in writing,
earlier than two or later than ten business days after the date of such notice.

         3. Upon the authorization by you of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus.

     (b) The documents to be delivered at each Time of Delivery by or on behalf
of the parties hereto pursuant to Section 7 hereof, including the cross receipt

City time, on the New York Business Day next preceding such Time of Delivery, at
which meeting the final drafts of the documents to be delivered pursuant to the
preceding sentence will be available for review by the parties hereto. For the

         amended Prospectus has been filed and to furnish you with copies
         thereof; to file promptly all reports and any definitive proxy or

         offering or sale of the Shares; to advise you, promptly after it
         receives notice thereof, of the issuance by the Commission of any stop

         reasonably request to qualify the Shares for offering and sale under
         the securities laws of such jurisdictions as you may request and to
         comply with such laws so as to permit the continuance of sales and
         dealings therein in such jurisdictions for as long as may be necessary
         to complete the distribution of the Shares; provided that, in
         connection therewith, the Company shall not be required to qualify as a
         foreign corporation or to file a general consent to service of process
         in any jurisdiction;

            (c) Prior to 10:00 A.M., New York City time, on the New York

         expiration of nine months after the time of issue of the Prospectus in
         connection with the offering or sale of the Shares and if at such time
         any events shall have occurred as a result of which the Prospectus as
         then amended or supplemented would include an untrue statement of a
         material fact or omit to state any material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made when such Prospectus is delivered, not misleading,
         or, if for any other reason it shall be necessary during such period to
         amend or supplement the Prospectus or to file under the Exchange Act

         comply with the Act or the Exchange Act, to notify you and upon your
         request to file such document and to prepare and furnish without charge
         to each Underwriter and to any dealer in securities as many copies as
         you may from time to time reasonably request of an amended Prospectus
         or a supplement to the Prospectus which will correct such statement or
         omission or effect such compliance, and in case any Underwriter is
         required to deliver a prospectus in connection with sales of any of the
         Shares at any time nine months or more after the time of issue of the
         Prospectus, upon your request but at the expense of such Underwriter,
         to prepare and deliver to such Underwriter as many copies as you may
         request of an amended or supplemented Prospectus complying with Section

            (e) During the period beginning from the date hereof and continuing
         to and including the date 90 days after the date of the Prospectus, not
         to offer, sell, contract to sell or otherwise dispose of, except as
         provided hereunder, any securities of the Company that are
         substantially similar to the Shares, including but not limited to any
         securities that are convertible into or exchangeable for, or that
         represent the right to receive, Stock or any such substantially similar

         involving a public offering) which include or relate to
         business-related arrangements, or (iii) employee stock option plans

         the Company and its subsidiaries are consolidated in reports furnished

                   (i) The Company has been duly qualified as a foreign
               corporation for the transaction of business and is in good
               standing under the laws of each jurisdiction in which it owns or
               leases properties, or conducts any business, so as to require
               such qualification, or is subject to no material liability or
               disability by reason of failure to be so qualified in any such
               jurisdiction (such counsel being entitled to rely in respect of
               the opinion in this clause (i) upon opinions of local counsel and

               the Company; provided that such counsel shall state that he
               believes that both you and he are justified in relying upon such
               opinions and certificates);

                   (ii)The Company and its subsidiaries have good and marketable
               title in fee simple to all real property owned by them, in each
               case free and clear of all liens, encumbrances and defects except
               such as are described in the Prospectus or such as do not
               materially affect the value of such property and do not interfere
               in any material respect with the use made and proposed to be made
               of such property by the Company and its subsidiaries; and any
               real property and buildings held under lease by the Company and
               its subsidiaries are held by them under valid, subsisting and
               enforceable leases with such exceptions as are not material and
               do not interfere in any material respect with the use made and
               proposed to be made of such property and buildings by the Company
               and its subsidiaries (in giving the opinion in this clause (ii),
               such counsel may state that no examination of record titles for
               the purpose of such opinion has been made, and that he is relying
               upon a general review of the titles of the Company and its
               subsidiaries, upon opinions of local counsel and abstracts,
               reports and policies of title companies rendered or issued at or
               subsequent to the time of acquisition of such property by the
               Company or its subsidiaries, upon opinions of counsel to the
               lessors of such property and, in respect of matters of fact, upon
               certificates of officers of the Company or its subsidiaries;
               provided that such counsel shall state that he believes that both
               you and he are justified in relying upon such opinions,
               abstracts, reports, policies and certificates);

                    (iii)To the best of such counsel's knowledge and other than
               as set forth or incorporated by reference in the Prospectus,
               there are no legal or governmental proceedings pending to which
               the Company or any of its subsidiaries is a party or of which any
               property of the Company or any of its subsidiaries is the subject
               which, individually or in the aggregate, would have, or may
               reasonably be expected to have, a material adverse effect on the
               current or future consolidated financial position stockholders'
               equity or results of operations of the Company and its
               subsidiaries; and, to the best of such counsel's knowledge, no
               such




                                       11
<PAGE>



               proceedings are threatened or contemplated by governmental
               authorities or threatened by others;

                  (iv) The compliance by the Company with all of the provisions
               of this Agreement and the consummation of the transactions herein
               contemplated will not conflict with or result in a breach or
               violation of any of the terms or provisions of, or constitute a
               default under, any indenture, mortgage, deed of trust, loan
               agreement or other agreement or instrument known to such counsel
               to which the Company or any of its subsidiaries is a party or by
               which the Company or any of its subsidiaries is bound or to which
               any of the property or assets of the Company or any of its
               subsidiaries is subject and which is material to the Company and
               its subsidiaries, nor will such action result in any violation of
               the provisions of the Certificate of Incorporation or By-laws of
               the Company or any statute or any order, rule or regulation known
               to such counsel of any court or governmental agency or body
               having jurisdiction over the Company or any of its subsidiaries
               or any of their properties;

                   (v) No consent, approval, authorization or order of or with
               any court or governmental agency or body of the Commonwealth of
               Pennsylvania or the United States of America is required to be
               obtained by the Company for the sale of the Securities or the
               consummation by the Company of the transactions contemplated by
               the Underwriting Agreement, except such as have been obtained
               under the Act and such as may be required under state securities
               or Blue Sky laws in connection with the purchase and distribution
               of the Securities by the Underwriters;

                  (vi) The documents incorporated by reference in the Prospectus
               or any further amendment or supplement thereto made by the
               Company prior to such Time of Delivery (other than the financial
               statements, related schedules and other financial data included
               or incorporated by reference therein, as to which such counsel
               need express no opinion), when they became effective or were
               filed with the Commission, as the case may be, appeared on their
               face to be responsive as to form in all material respects with
               the requirements of the Act or the Exchange Act, as applicable,
               and the rules and regulations of the Commission thereunder; and
               he has no reason to believe that any of such documents, when such
               documents became effective or were so filed, as the case may be,
               contained, in the case of a registration statement which became
               effective under the Act, an untrue statement of a material fact,
               or omitted to state a material fact required to be stated therein
               or necessary to make the statements therein not misleading, or,
               in the case of other documents which were filed under the
               Exchange Act with the Commission, an untrue statement of a
               material fact or omitted to state a material fact necessary in
               order to make the statements therein, in the light of the
               circumstances under which they were made when such documents were
               so filed, not misleading; and

                   (vii) The Registration Statement and the Prospectus and any
               further amendments and supplements thereto made by the Company

               In rendering such opinions, such counsel may state that he
         expresses no opinion as to the laws of any jurisdiction other than the
         laws of the United States of America and the laws of the Commonwealth
         of Pennsylvania and, to the extent relevant, the General Corporation
         Law of the State of Delaware.

            (d) Fried, Frank, Harris, Shriver & Jacobson, counsel for the
         Company, shall have furnished to you their written opinion (a draft of
         such opinion is attached as Annex I(c) hereto), dated such Time of
         Delivery, in form and substance satisfactory to you, to the effect
         that:

                   (i) The Company has been duly incorporated and is validly
               existing as a corporation in good standing under the laws of the
               State of Delaware, with corporate power and authority to own its
               properties and conduct its business as described in the
               Prospectus;

                   (ii)The Company has an authorized capitalization as set forth
               in the Prospectus, and all of the issued shares of capital stock
               of the Company (including the Shares being sold at such Time of
               Delivery) have been duly and validly authorized and issued and
               are fully paid and non-assessable; and the Shares conform as to
               legal matters to the description of the Stock contained in the
               Prospectus;

                    (iii) This Agreement has been duly authorized, executed and
               delivered by the Company;

                 (iv) The documents incorporated by reference in the Prospectus
               or any further amendment or supplement thereto made by the
               Company prior to such Time of Delivery (other than the financial
               statements, related schedules and other financial data included
               or incorporated by reference therein, as to which such counsel
               need express no opinion), when they became effective or were
               filed with the Commission, as the case may be, appeared on their
               face to be responsive as to form in all material respects with
               the requirements of the Exchange Act and the rules and
               regulations of the Commission thereunder; and

                   (v) The Registration Statement and the Prospectus (other than
               the financial statements, related schedules and other financial
               data included or incorporated by reference therein, as to which
               such counsel need express no opinion) as of their respective
               effective or issue dates, appeared on their face to be responsive
               as to form in all material respects with the requirements of the
               Act and the rules and regulations thereunder; no facts have come
               to their attention that caused them to believe that, as of its
               effective date, the Registration Statement or any further
               amendments thereto made by the Company prior to such Time of
               Delivery contained an untrue statement of a material fact or
               omitted to state a material fact required to be stated therein or
               necessary to make the statements therein not misleading. They
               express no view or belief, however, with respect to financial
               statements and related notes and schedules and other financial
               data included in or incorporated by reference in or omitted from
               the Registration Statement. Also, no facts have come to their
               attention that caused them to believe that the Prospectus, as of
               its date, or any further amendments or




                                       13

               Delivery contained an untrue statement of a material fact or
               omitted to state a material fact necessary to make the statements
               therein, in light of the circumstances in which they were made,
               not misleading, and no facts have come to their attention that
               caused them to believe that the Prospectus, at such Time of
               Delivery, or any further amendments thereto made by the Company
               prior to such Time of Delivery, contains an untrue statement of a
               material fact or omits to state a material fact necessary to make
               the statements therein, in light of the circumstances in which
               they were made, not misleading.

               In rendering such opinion, such counsel may state that they
         express no opinion as to the laws of any jurisdiction other than the
         laws of the State of New York, the Federal laws of the United States
         and the General Corporation Law of the State of Delaware;

         Stockholder (a draft of such opinion is attached as Annex I(d) hereto),
         dated such Time of Delivery, in form and substance satisfactory to you,
         to the effect that:

                   (i) The Power of Attorney and Custody Agreement have been
               duly executed and delivered by MBO-IV and constitute valid and

               insolvency, reorganization, moratorium, fraudulent transfer or
               other similar laws affecting creditors' rights generally and (B)
               general principles of equity (whether considered in a proceeding

               with all of the provisions of this Agreement, the Power of
               Attorney and the Custody Agreement, and the consummation of the
               transactions herein and therein contemplated will not conflict
               with or result in a breach or violation of any terms or
               provisions of, or constitute a default under, any statute of the
               State of New York or the United States of America, any indenture,
               mortgage, deed of trust, loan agreement or other agreement or
               instrument identified to such counsel by the general partner of
               MBO-IV to which MBO-IV is a party or by which MBO-IV is bound or

               the Partnership Agreement of MBO-IV, or any order, rule or
               regulation identified to such counsel by the general partner of
               MBO-IV of any court or governmental agency or body of the State
               of New York or the United States of America having jurisdiction
               over MBO-IV or the property of MBO-IV;

                   (iii) No consent, approval, authorization or order of any

               the transactions contemplated by this Agreement in connection
               with the Shares to be sold by MBO-IV pursuant to this Agreement,
               except such as have been obtained under the Act and such as may
               be required under state securities or Blue Sky laws in connection
               with the purchase and distribution of the Shares by the
               Underwriters; and

                   (iv) Assuming that the Underwriters purchase the Shares to be
               sold by MBO-IV to the Underwriters at such Time of Delivery for
               value and without notice of any "adverse claim" (as defined in
               Section 8-102 of the UCC), upon the crediting of the
               Underwriters' accounts with such Shares in the records of DTC,
               Cede & Co. or such other nominee designated by DTC will acquire
               all rights that MBO-IV had in the Shares and will be a "protected
               purchaser" of such Shares (as defined in Section 8-303 of the
               UCC), the Underwriters will acquire a valid "security

               8-102 of the UCC) may be asserted against the Underwriters with
               respect to such security entitlement;

            (f) Fried, Frank, Harris, Shriver & Jacobson, counsel for each of
         the Selling Stockholders, shall have furnished to you their written
         opinion with respect to each of the Selling Stockholders other than

               Underwriters will acquire a valid "security entitlement" (within
               the meaning of Section 8-501 of the UCC) to such Shares, and no
               action based on an "adverse claim" (as defined in Section 8-102

               Stockholder in accordance with their terms, subject as to
               enforcement to (A) applicable bankruptcy, insolvency,
               reorganization, moratorium, fraudulent transfer or other similar
               laws affecting creditors' rights generally and (B) general
               principles of equity (whether considered in a proceeding at law
               or in equity);

               of Delivery for value and without notice of any "adverse claim"

            (h) On the date of the Prospectus at a time prior to the execution

         position, stockholders' equity or results of operations of the Company
         and its subsidiaries, otherwise than as set forth or contemplated in
         the Prospectus, the effect of which, in any such case described in
         clause (i) or (ii), is in the judgment of the Representatives so

         effect of any such event specified in this clause (iv) in the judgment
         of Goldman, Sachs & Co., as representatives of the various
         Underwriters, makes it impracticable or inadvisable to proceed with the

         Company and the Selling Stockholders of all of their respective
         obligations hereunder to be performed at or prior to such Time of
         Delivery, and as to such other matters as you may reasonably request,
         and the Company shall have furnished or caused to be furnished
         certificates as to the matters set forth in subsections (a) and (i) of
         this Section.

     8. (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through you expressly for use therein; and provided, further, that the Company
shall not be liable to any Underwriter under the indemnity agreement in this
subsection (a) with respect to any Preliminary Prospectus to the extent that any
such loss, claim, damage or liability of such Underwriter results from the fact
that such Underwriter sold Shares to a person as to whom it shall be established
that there was not sent or given, at or prior to the written confirmation of
such sale, a copy of the Prospectus or of the Prospectus as then amended or
supplemented in any case where such delivery is required by the Act if the
Company has previously furnished copies thereof in sufficient quantity to such
Underwriter and the loss, claim, damage or liability of such Underwriter results
from an untrue statement or omission of a material fact contained in the
Preliminary Prospectus which was identified in writing at such time to such
Underwriter and corrected in the Prospectus or in the Prospectus as then amended
or supplemented.

     (b) MBO-IV (the "Indemnifying Stockholder"), in proportion to the number of
Shares to be sold by it hereunder, will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse each Underwriter for
any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that the Indemnifying Stockholder
shall not be liable in any such case to the extent




                                       17
<PAGE>





that any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Prospectus, the Registration Statement or the Prospectus
or any such amendment or supplement in reliance upon or in conformity with
written information furnished to the Company by any Underwriter through you
expressly for use therein; and provided, further, that the Indemnifying
Stockholder shall not be liable to any Underwriter under the indemnity agreement
in this subsection (b) with respect to any Preliminary Prospectus to the extent
that any such loss, claim, damage or liability of such Underwriter results from
the fact that such Underwriter sold Shares to a person as to whom it shall be
established that there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the Prospectus or of the Prospectus as then
amended or supplemented in any case where such delivery is required by the Act
if the Company or the Indemnifying Stockholder have previously furnished copies
thereof in sufficient quantity to such Underwriter and the loss, claim, damage
or liability of such Underwriter results from an untrue statement or omission of
a material fact contained in the Preliminary Prospectus which was identified in
writing at such time to such Underwriter and corrected in the Prospectus or in
the Prospectus as then amended or supplemented. Notwithstanding the provisions
of this subsection (b), the Indemnifying Stockholder shall not be required to
pay an amount in excess of the gross proceeds received by it from the Shares
sold by it hereunder.

     (c) Each of the Selling Stockholders, severally in proportion to the number
of Shares to be sold by such Selling Stockholder hereunder, will indemnify and
hold harmless the Company and each Underwriter against any losses, claims,
damages or liabilities, joint or several, to which such Underwriter may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse each Underwriter for any legal or other expenses reasonably incurred
by such Underwriter in connection with investigating or defending any such
action or claim as such expenses are incurred, in each case to the extent, but
only to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in any Preliminary Prospectus, the
Registration Statement or the Prospectus or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by such Selling Stockholder expressly for use therein; provided,
however, that the Selling Stockholders shall not be liable to any Underwriter
under the indemnity agreement in this subsection (c) with respect to any
Preliminary Prospectus to the extent that any such loss, claim, damage or
liability of such Underwriter results from the fact that such Underwriter sold
Shares to a person as to whom it shall be established that there was not sent or
given, at or prior to the written confirmation of such sale, a copy of the
Prospectus or of the Prospectus as then amended or supplemented in any case
where such delivery is required by the Act if the Company or the Selling
Stockholders have previously furnished copies thereof in sufficient quantity to
such Underwriter and the loss, claim, damage or liability of such Underwriter
results from an untrue statement or omission of a material fact contained in the
Preliminary Prospectus which was identified in writing at such time to such
Underwriter and corrected in the Prospectus or in the Prospectus as then amended
or supplemented. Notwithstanding the provisions of this subsection (c), no
Selling Stockholder shall be required to pay an amount in excess of the gross
proceeds received by such Selling Stockholder from the Shares sold by it
hereunder.

     (d) Each Underwriter will indemnify and hold harmless the Company and each
Selling Stockholder against any losses, claims, damages or liabilities to which
the Company or such Selling Stockholder may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the



                                       18
<PAGE>



omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement or the Prospectus or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through Goldman, Sachs
& Co. expressly for use therein; and will reimburse the Company and each Selling
Stockholder for any legal or other expenses reasonably incurred by the Company
or such Selling Stockholder in connection with investigating or defending any
such action or claim as such expenses are incurred.

     (e) Promptly after receipt by an indemnified party under subsection (a),
(b), (c) or (d) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation.

     (f) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a), (b),
(c) or (d) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Stockholders on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (e) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Stockholders on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Selling Stockholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering of the Shares purchased under this
Agreement (before deducting expenses) received by the Selling Stockholders bear
to the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Selling Stockholders on the one hand or the
Underwriters on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, each of the Selling Stockholders and the Underwriters agree that it
would not be just and equitable if contributions pursuant to this subsection (f)
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (f). The amount paid or payable by an indemnified




                                       19
<PAGE>



party as a result of the losses, claims, damages or liabilities (or actions in
respect thereof) referred to above in this subsection (f) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (f), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission, and no Selling Stockholder shall be
required to contribute, in the aggregate, any amount in excess of the gross
proceeds received by such Selling Stockholder from the Shares sold by it
hereunder. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Underwriters'
obligations in this subsection (f) to contribute are several in proportion to
their respective underwriting obligations and not joint.

     (g) The obligations of the Company, the Indemnifying Stockholder and the
Selling Stockholders under this Section 8 shall be in addition to any liability
which the Company, the Indemnifying Stockholder and the respective Selling
Stockholders may otherwise have and shall extend, upon the same terms and
conditions, to each person, if any, who controls any Underwriter within the
meaning of the Act; and the obligations of the Underwriters under this Section 8
shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company, to each partner of any Selling Stockholder
that is a partnership and to each person, if any, who controls the Company or
any Selling Stockholder within the meaning of the Act.

     9. (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Selling Stockholders shall be entitled to a further period of
thirty-six hours within which to procure another party or other parties
satisfactory to you to purchase such Shares on such terms. In the event that,
within the respective prescribed periods, you notify the Selling Stockholders
that you have so arranged for the purchase of such Shares, or the Selling
Stockholders notify you that they have so arranged for the purchase of such
Shares, you or the Selling Stockholders shall have the right to postpone a Time
of Delivery for a period of not more than seven days, in order to effect
whatever changes may thereby be made necessary in the Registration Statement or
the Prospectus, or in any other documents or arrangements, and the Company
agrees to file promptly any amendments to the Registration Statement or the
Prospectus which in your opinion may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to this Agreement with respect to such Shares.

     (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Selling
Stockholders as provided in subsection (a) above, the aggregate number of such
Shares which remains unpurchased does not exceed one-eleventh of the aggregate
number of all the Shares to be purchased at such Time of Delivery, then the
Selling Stockholders shall have the right to require each non-defaulting
Underwriter to purchase the number of Shares which such Underwriter agreed to
purchase hereunder at such Time of Delivery and, in addition, to require each
non-defaulting Underwriter to purchase its pro rata share (based on the number
of Shares which such Underwriter agreed to purchase hereunder) of the Shares of
such defaulting Underwriter or Underwriters for which such arrangements have not
been made; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

     (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Selling
Stockholders as provided in subsection (a) above, the aggregate number of such
Shares which remains unpurchased exceeds one-eleventh of the




                                       20
<PAGE>



aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Selling Stockholders shall not exercise the right described in
subsection (b) above to require non-defaulting Underwriters to purchase Shares
of a defaulting Underwriter or Underwriters, then this Agreement (or, with
respect to the Second Time of Delivery, the obligations of the Underwriters to
purchase and of the Selling Stockholders to sell the Optional Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company or the Selling Stockholders, except for the expenses
to be borne by the Company, the Selling Stockholders and the Underwriters as
provided in Section 6 hereof and the indemnity and contribution agreements in
Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

     10. The respective indemnities, agreements, representations, warranties and
other statements of the Company, the Selling Stockholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company, or any of the Selling Stockholders, or any officer
or director or controlling person of the Company, or any controlling person of
any Selling Stockholder, or any partner of any Selling Stockholder that is a
partnership, and shall survive delivery of and payment for the Shares.

     11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Selling Stockholders as provided herein, each of the Selling Stockholders pro
rata (based on the number of Shares to be sold by such Selling Stockholder
hereunder) will reimburse the Underwriters through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Underwriters in making preparations for the
purchase, sale and delivery of the Shares not so delivered, but the Company and
the Selling Stockholders shall then be under no further liability to any
Underwriter in respect of the Shares not so delivered except as provided in
Sections 6 and 8 hereof.

     12. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you; and in all dealings with any Selling Stockholder hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Stockholder made or given by the
Attorney-in-Fact for such Selling Stockholder.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives at 32 Old Slip, 9th Floor,
New York, New York 10004, Attention: Registration Department; if to any Selling
Stockholder shall be delivered or sent by mail, telex or facsimile transmission
to such Selling Stockholder's Attorney-in-Fact at its address set forth in
Schedule II hereto; and if to the Company shall be delivered or sent by mail,
telex or facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(e) hereof shall be delivered or sent by
mail, telex or facsimile transmission to such Underwriter at its address set
forth in its Underwriters' Questionnaire or telex constituting such
Questionnaire, which address will be supplied to the Company or the Selling
Stockholders by you on request. Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

     13. This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and the Selling Stockholders and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company, each partner of any Selling Stockholder that is a partnership and each
person who controls the Company, any Selling Stockholder or any Underwriter, and
their respective heirs, executors, administrators, successors and assigns, and
no other person shall acquire or have any


                                       21
<PAGE>



right under or by virtue of this Agreement. No purchaser of any of the Shares
from any Underwriter shall be deemed a successor or assign by reason merely of
such purchase.

     14. Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15. This Agreement shall be governed by and construed in accordance with
the laws of the State of New York.

     16. This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts, each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us five counterparts hereof, and upon the acceptance hereof by you, on
behalf of each of the Underwriters, this letter and such acceptance hereof shall
constitute a binding agreement among each of the Underwriters, the Company and
each of the Selling Stockholders. It is understood that your acceptance of this
letter on behalf of each of the Underwriters is pursuant to the authority set
forth in a form of Agreement among Underwriters, the form of which shall be
submitted to the Company and the Selling Stockholders for examination, upon
request, but without warranty on your part as to the authority of the signers
thereof.

                           ----------------------------------

Ladies and Gentlemen:

                  We have acted as special counsel for General Instrument
Corporation, a Delaware corporation (the "Company"), in connection with the
underwritten public offering (the "Offering") by certain of the Company's
stockholders of shares (the "Shares") of common stock, par value $.01 per share
(the "Common Stock") of the Company, including Shares that may be offered and
sold upon the exercise of an over-allotment option granted to the underwriters.
The Shares are to be offered to the public pursuant to an underwriting agreement
among the Company, the selling stockholders named therein, and Goldman, Sachs &
Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Lazard Freres & Co.
LLC, as representatives of the underwriters (the "Underwriting Agreement").

                  With your permission, all assumptions and statements of
reliance herein have been made without any independent investigation or
verification on our part except to the extent otherwise expressly stated, and we
express no opinion with respect to the subject matter or accuracy of such
assumptions or items relied upon.

                  In connection with this opinion, we have (i) investigated such
questions of law, (ii) examined originals or certified, conformed or
reproduction copies of such agreements, instruments, documents and records of
the Company, such certificates of public officials and such other documents, and
(iii) received such information from officers and representatives of the Company
as we have deemed necessary or appropriate for the purposes of this opinion. In
all examinations, we have assumed the legal capacity of all natural persons
executing documents, the genuineness of all signatures, the authenticity of
original and certified documents and the conformity to original or certified
copies of all copies submitted to us as conformed or reproduction copies. As to
various

                                                            August 26, 1998

questions of fact relevant to the opinions expressed herein, we have relied
upon, and assume the accuracy of, representations and warranties contained in
the documents and certificates and oral or written statements and other
information of or from representatives of the Company and others and assume
compliance on the part of all parties to the documents with their covenants and
agreements contained therein.

                  Based upon the foregoing and subject to the limitations,
qualifications and assumptions set forth herein, we are of the opinion that the
Shares are duly authorized, validly issued, fully paid and non-assessable.

                  The opinion expressed herein is limited to the General
Corporation Law of the State of Delaware, as currently in effect.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the reference to this firm under the
caption "Validity of Common Stock" in the Prospectus forming part of the
Registration Statement. In giving such consent, we do not hereby admit that we
are in the category of such persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended.

                                                   Very truly yours,

Buyout Partnership-IV, a New York limited partnership ("MBO-IV"), and the
individual selling stockholders listed on Schedule A hereto (the "Individual
Selling Stockholders" and, together with MBO-IV, the "Selling Stockholders").

    WHEREAS, the Company has filed a registration statement with the Securities
and Exchange Commission relating to an underwritten public offering (the
"Offering") of shares of the Company's common stock, par value $.01 per share
(the "Common Stock"); and

    WHEREAS, each of MBO-IV and the Individual Selling Stockholders have granted

Shares"); and

    WHEREAS, the Company desires to purchase from the Selling Stockholders, and
the Selling Stockholders desire to sell to the Company, all or a portion of the
Offered Shares.

    NOW, THEREFORE, in consideration of the mutual covenants and undertakings
contained herein, and on the terms and subject to the conditions set forth
herein, the parties hereto, each representing to the others that its execution,
delivery and performance of this Agreement has been fully and duly authorized,

         (a)  The Closing shall take place at the offices of Fried, Frank,

              practicable, and in any event within five Business Days, after the
              earlier of (i) the expiration of the 30-day period during which
              the Underwriters have the right to exercise their over-allotment
              option, without such options having been exercised, and (ii) the
              receipt by the Company of written notice from Goldman, Sachs & Co.
              (on behalf of the Underwriters) that the Underwriters have either
              elected not to exercise their over-allotment option or have
              purchased only a portion (but not all) of the shares subject to
              their over-allotment option. It is understood and agreed that if
              their Underwriters exercise their over-allotment option in full,
              the Company will have no obligation to purchase, and the Selling
              Stockholders will have no obligation to sell, any Offered Shares

              proceeds from the Offering.

                   SECTION 3 - REPRESENTATIONS AND WARRANTIES

    3.1 By the Parties. Each Selling Stockholder represents and warrants as to
itself to the Company, and the Company represents and warrants as to itself to
the Selling Stockholders, as follows:

         (a)  It has all necessary authority for the execution, delivery and
              performance of this Agreement by it; it has duly executed and
              delivered this Agreement; and this Agreement is a valid and
              legally binding agreement, enforceable against it in accordance
              with its terms, assuming the due execution and delivery by the
              other parties; and

         (b)  The performance of this Agreement by it will not violate or

              such party is not required to obtain any governmental approvals or
              third party consents to enter into and perform its obligations
              pursuant to this Agreement. Such execution and performance does
              not and will not constitute a default under any agreement or
              obligation binding on it or result in the forfeiture or loss of
              any rights or assets by it except as specifically provided for in
              this Agreement.

    3.2 By the Selling Stockholders. Each Selling Stockholder represents and
warrants to the Company that it owns the Purchase Shares to be sold hereunder by
such Selling Stockholder to the Company, beneficially and of record, free and
clear of any liens, charges or encumbrances and that upon delivery of its
Purchase Shares, and payment therefore pursuant hereto, good and valid title to
its Purchase Shares will pass to the Company (assuming that the Company is
without notice of any adverse claim, as defined in the Uniform Commercial Code
as adopted in the State of New York (the "Code") and is otherwise a bona fide
purchaser for the purposes of the Code).
